Advanced Cost Analysis and Systems - Assignment Example The Advanced Cost Analysis and Systems involves carrying out Business cycles for Apple Inc, which include Revenue--sales process, sales return, cash receipt Expenditure--purchasing, purchase return, cash disbursement Payroll Fixed Assets--Acquisition, dispose Inventory--production Treasury Cycle Finiancial. The payroll cycle begins by the receipt of time cards from the hourly employees. The time cards depict the number of hours worked by the employees in their respective departments. The head of the department either signs the time card for confirmation or does not sign to indicate rejection. The head of department then submits the time card to the payroll manager who then updates the payroll. The company’s CFO then reviews gives approval leading to the processing and posting of the payroll. Once the CFO authorizes the paychecks, the company then prepares adequate cash for disposal, in covering the amount indicated in the payroll. This triggers the preparation of a payroll voucher to act as a record for the total amount indicated in the payroll. After posting the payroll, the checks are then delivered to the employees. This transaction affects the cash department consequently triggering for the preparation of a disbursement journal. The company then reconciles the ledger informa tion. As depicted in the flow chart showing sales process, the first step is a customer placing an order for the company’s products. The company presents the customer with the details of products before the actual transaction starts. As a legal procedure, customer purchase order forms an inherent part of the transactions and must include company name, customer’s name, fabric, quantities, shipping and billing information. The receipt of the purchase order drives the company to approving the order and accompanied credit carried by the customer for the transaction. in the shipping process, the company makes use of a common

Deals with the Devil Essay Example for Free

Deals with the Devil Essay The Devil is portrayed in many ways and throughout many different types of literature, movies, and music. The most iconic image of the devil is a red beast with horns, a pointed tail, and a pitchfork in his hand. This famous image depicts an evil monster that is in the depths of hell where he rules over the other evil beings of the world. This is only one image of many that you can find in a vast amount of literature and media both past and present. In The Devil and Tom Walker, the devil is described as a black woodsman, human in form but with red eyes. Similarly in The Devil and Daniel Webster, the Devil is described as a â€Å"dark-dressed stranger,† who is soft spoken but has an evil smile. In these descriptions you still get a sense of evil from the Devil but he is in human form. So what or who is the Devil? From early stories in Christianity, Lucifer commonly known as Satan or the Devil is originally an archangel created in the image of God. He is the highest form of an angel, but challenges God and is cast down to rule the pits of hell. Can someone created in the image of God as Christianity suggests be a dark stranger or a red beast? The Devil can be depicted in many ways, but what the Devil really represents is the existence greed and moral corruptness in society. Regardless of the imagery, the Devil plays a similar role throughout literature and media both past and present. One of the earliest stories of a man making a pact with the Devil is a character named Faust, from an old German legend. Faust was a brilliant scholar but always wanted more knowledge. The Devil comes to him one night and promises him infinite wisdom for a certain amount of time after which Faust’s soul would be owned by the Devil. Faust readily agrees and signs a contract with the Devil. Faust lives with his infinite knowledge until the year comes when the Devil comes to collect his soul. Faust is then taken by the Devil and spends the rest of eternity in hell. This story maybe one of the original stories of the Devil making a deal with a man for his soul. The Devil knows and uses the man’s greatest desire to lure him into signing a contract to get his soul. Man is easily corruptible when promised his deepest desire and choses instant gratification without fully understanding or thinking of the repercussions. In Anne Rice’s novel Memnoch the Devil, the Devil begins to stalk Lestate until one evening he appears to him and takes him on a voyage. Lestate is a very old and powerful Vampire, known to only look out himself and his own needs. The Devil takes Lestate to Heaven and Hell where he tells Lestate the story of the beginning of time when God created the world and human beings. Memnoch, or the Devil, spent a lot of time on Earth admiring God’s creation, but begins to notice the suffering and pain of human beings and the souls of deceased that are stuck in between Heaven and Earth. He describes God as uncaring of the evil in the world he created and begs God to do something to help the humans that are suffering on Earth and Sheol, which is the afterlife. Memnoch claims that he is not evil in fact he was an archangel created in God’s image, but because he questioned God several times about why he is letting humans suffer God gets angry. God casts him out of Heaven to find all the lost souls on earth and Sheol that he thinks deserves to be in the Kingdom of Heaven, before Memnoch can return. This turns out to be a daunting task and he enlists Lestate to be his partner and adversary of God. This journey throws Lestate to question everything he has ever known about God and the Devil, sfor he has lived centuries and had dismissed such notion that Heaven and Hell exist. Lestate ends up running from the Devil and when he returns to Earth he steals a biblical artifact, Veronica’s Veil, he reveals the artifact to the world. In the end it is revealed that the Devil was only using Lestate by allowing him to return with an artifact that would renew faith in God and therefore limit the amount of souls sent to Hell. In this story the Devil is manipulative and cunning though he claims he is not evil. Although Lestate never made a deal with the Devil, the Devil won by using Lestate’s narcissism for his own purposes. In the Phantom of the Opera, a popular Broadway show, one can view the Devil as the representation of the masked phantom in the opera house. The young understudy Christine hears a beautiful voice calling to her when she arrives at the opera house. She had heard stories of an â€Å"Angel of Music† who could give her a more powerful and beautiful voice and readily begins to sing with the Devil. A series of mysterious accidents forces the lead singer to lose her voice therefore losing the star role in the opera. Christine is the given then given the lead role after her voice improves drastically while practicing with the Devil. â€Å"The Angel of Music† takes Christine to the depths of the opera house tunnels against her will. Christine is in love with another man, who searches for her in the tunnels of the opera house. The Devil captures Christine’s love and tells her he will kill him if she doesn’t stay with him. This story is similar to the short stories of The Devil and Tom Walker and The Devil and Daniel Webster, in that the characters make a deal with the Devil to improve some aspect of their lives but when the Devil wants to collect on their deal none of the characters want to go willingly. One noticeable difference between the stories is that in the end of The Phantom of the Opera Christine shows kindness to the â€Å"Angel of Music† and he lets her go and he disappears forever leaving only his mask behind. Overall mankind has shown a pattern of making deals with the devil for their desires to their own detriment. From the short stories of, The Devil and Daniel Webster and The Devil and Tom Walker, to the legend of Faust, and the Phantom of the Opera musical you can see similarities in all the characters desiring something unattainable. The Devil then comes to them and promises to deliver their wishes for a small price, merely their souls for the rest of eternity. The Devil feeds on the lack of moral integrity and uses this to gain power over these characters souls. On the other hand, in Memnoch the Devil, Anne Rice changes the â€Å"deal with the devil† theme because Lestate never actually bargains with the devil, none the less the Devil gets what he desires. As you can see, literature and other mediums have adapted the story of making a pact with the Devil in many ways. Works Cited Faust. (n.d.).

Laminar Air-flow to Control Operating Room Infection

Laminar Air-flow to Control Operating Room Infection INTRODUCTION Surgical site infections (SSIs) are defined as infections occurring within 30 days after surgical operation or within one year if an implant is left in place and affecting either the incision or deep tissue at the operation site (Owens and Stoessel 2008). SSIs are reported as the major cause of high morbidity and mortality among post -operative patients (Weigelt et.al. 2010). According to UK National Joint Registry Report, during 2003 -2006 period infection was responsible for about 19 % failure of joint surgery resulting in revision procedures (Sandiford and skinner 2009). Micro-organisms in the air particles settle on the wound, dressings and surgical instruments and cause infections (Chow and Yang 2005). Whyte et.al (1982) identified that contamination from patients skin as the cause of infection in 2% cases and from theatre personnel in 98% cases. They also found that in 30% cases, contaminants reach the wound from theatre personnel via air and in 70% cases it is via hands. Generally air quality in the operating room is maintained ventilation system. Additional improvements can be achieved by laminar air-flow system or UV lights. Laminar air-flow system is expensive and require continues maintenance. Its installation increases building cost and the operational cost (Cacciariet.al., 2004: Hansen, 2005). Studies conducted to evaluate the effectiveness of laminar flow produced mixed results and there is no consensus on its role in infection control (Sandiford 2007). In this setting, this paper reviews the recent studies to examine the effectiveness of laminar air-flow in reducing SSIs. Studies for this review were found by searching on databases such as CINAHL, PubMed, Science Direct, Ovidsp, Science Citation Index (ISI) and Google scholar. Keywords used for this search are laminar air flow, surgical site infection, operating room air quality, airborne infections + operating theatre, LMA + infection control. As laminar air-flow is used mainly in orthopaedic theatres, majority of the studies are on joint surgery. OPERATING THEATRE AIR QUALITY AND INFECTION CONTROL Indoor air in an operating theatre contains dust which consists of substances released from disinfectant and sterilizers, respiratory droplets, insect parts smoke released from cautry. Dust particles act as a carrier for transporting microorganisms laden particles and can settle on surgical wound and there by cause infection (Neil 2005). Air particles are found to be responsible for about 80% 90% of microbial contamination (CDC 2005). Modern operating theatres are generally equipped with conventional ventilation system in which filters can remove airborne particles of size >5mm about 80-95% (Dharan 2002). The efficacy of operating room ventilation is measured by the colony forming units (CFU) of organisms present per cubic meter. The conventional ventilation (Plenum) with 20 air exchanges is considered efficient if it achieves the colony count of 35cfu/m3 or less (Bannister 2002). Ventilation system with laminar air-flow directs the air-flow in one direction and sweeps the air particle over the wound site to the exits (CDC 2003). Laminar air-flow with HEPA (High Efficiency Particulate Arrestment) filters system has the capacity to remove air particles of size 0.3  µm up to 99.9 % and can produce 300 air exchanges per hour in ultraclean orthopaedic theatres. (Sandiford and skinner 2009). Laminar air-flow units are generally two types; ceiling-mounted (vertical flow) or wall-mounted (horizontal flow). There are inconveniences associated with both types. Generally the major problem associated with laminar air-flow is flow disruption. With vertical laminar flow, it is the heat generated by surgical lamps creates air turbulence while with horizontal laminar flow it is the surgical team that disrupt the air-flow (Dharan 2002). LAMINAR AIR FLOW IN INFECTION CONTROLL Laminar air-flow system is mainly used in implant surgeries where even a small number of microorganisms can cause infection. In joint replacement surgeries, one of the main causes of early (within 3 months) and delayed (within 18 months to 2 years) deep prosthetic infections was found colonisation during surgery (Knobben 2006). Laminar air flow is supposed to minimize contamination by mobilizing uniform and large volume of clean air to the surgical area and Contaminants are flushed out instantly (Chow and Yang, 2004). Some studies found that this method is effective in reducing infection but some others produced contradicting results (give some reference) A recent study conducted by Kakwani et.al. (2007) found that laminar air-flow system is effective in reducing the reoperation rate in Austin-Moore hemiarthroplasty. Their study compared the reoperation rate between theatres with laminar air-flow and theatres without laminar air-flow system. A cohort of 435 patients who had Austin-Moore hemiarthroplasties at Good Hope Hospital in Birmingham between August 2000 and July 2004 were selected for this study. Of those 435 patients, 212 had operation in laminar air-flow theatres and 223 had operation in non-laminar air-flow theatres. Data were collected by reviewing case notes and radiographs. For all cases antibiotics were administrated and water impervious surgical gowns and drapes were used. In the non-laminar air-flow group it was found that the re-operation rate for all indication in the first year after hemiarthroplasties was 5.8 % (13/223), while in the laminar air-flow group it was 1.4% (3/212). Analysis found that there were no stat istically significant relation between re-operation rate and water impervious gown and drapes (p=0.15), while use of laminar air-flow found a statistically significant drop (p=0.0285) in re-operation rate within the first year after hemiarthroplasties. They found that re-operation rate in no-laminar air-flow theatres were four times greater than that in laminar airflow theatres. Even though the aim of the study was clearly described there was no review of existing studies to identify the gap in the research. Study methods and details of statistical analysis were given elaborately. The sample size seems sufficient. Results were summarized and presented using graphs and charts. Discussion of results was short and seems not adequate to address the objectives of the study. There was no attempt to explain the casual relationship. For example researches were making statements such as à ¢Ã¢â€š ¬Ã‚ ¦the introduction of water-impervious drapes and gowns did not seem to make a statistically significant improvement in the resultà ¢Ã¢â€š ¬Ã‚ ¦. (p.823). Researchers failed to acknowledge any limitations of the study. Data for this study was collected by reviewing patients records. Patients records are considers as confidential and researchers didnt mention whether they received consent from the patients or ethical approval form institution to conduct the study. This ca n be considered as an ethical flaw of this study. There are studies which found that laminar air-flow system is not effective in reducing infection rate. In their study Brandt C et.al (2008) found that infection rate was substantially high in theatres with laminar air-flow system. This was a retrospective cohort-study based on routine surveillance data from German national nosocomial infections surveillance system (KISS). Hospitals which had performed at least 100 operations between the years 2000 and 2004 were selected for this study. Type of ventilation technology installed in operation rooms of selected hospitals were collected separately through questionnaire from infection control teams in the participating hospitals. Surgical departments were grouped into categories according to the type of ventilation system installed. Departments using artificial operating room (OR) ventilation with either turbulent or laminar airflow was included in this study. Total 63 surgical departments from 55 hospitals were included in this study. Analysis was performed to the data set created by merging the questionnaire data on OR ventilation and surveillance data from the KISS data base. The data set analysed contained 99230 operations with 1901 SSIs. Age and gender of the patient was found a significant risk factor of SSI in most procedures. Univariate analysis conducted found that rate of SSIs was high in departments with laminar air flow ventilation. Multivariate analysis also confirmed this finding. Authors argue that it may be due to the improper positioning theatre personnel in horizontal laminar flow room. Researches provided a well-researched literature review which clearly identified gap in current research. Objectives and design of the study was properly explained. Study was based on a large sample size. Results were discussed in detail and casual relations were well explained. Enough tables were used to present results. Limitations were properly discussed. Knobben et.al (2006) conducted an experimental study to evaluate how systemic changes together with behavioural changes can decreases intra-operative contamination. This study was conducted in the university Medical Centre Groningen, The Netherlands. A random sample of 207 surgical procedures which involved total knee or hip prosthesis from July 2001 to January 2004 was selected for this study. Two sequential series of behavioural and systemic changes were introduced to ascertain their role in reducing intra-operative contamination. The control group consisted 70 cases. Behavioural changes (correct use of plenum) were introduced to the first intervention group of 67 operations. Intense behavioural and systemic changes were introduced to second intervention group of 70 operations. The systemic changes introduced was the installation of new laminar flow with improved airflow from 2700m3/h to 8100m3/h. Two samples each were taken from used instruments, unused instruments and removed bon es. Control swabs were also collected to make sure that contamination was not occurred during transport and culturing. Early and late intra-operative contamination was also checked. All patients were monitored for any wound discharge while in hospital and followed-up for 18 months to check whether intra-operative contamination affects post-operative infection. Among the control group contamination was found 32.9% while in intervention group 1 it was 34.3% and in intervention group 2 it was 8.6%. Except in Group 1 (p=0.022) late phase contamination was not significantly higher than early phase contamination. During the control period wound discharge was found in 22.9% patients and 11.4% of them had wound infection later. Deep periprosthetic infection had been found in 7.1% of them in the follow-up period. Deep periprosthetic infection was found in 4.5% cases of first intervention group and in 1.4% of cases in second intervention group in the follow-up period. But none of these decreases were found statistically significant. Contamination, prolonged wound discharge and superficial surgical site infection were found decreased after both first and second intervention. But a statistically significant reduction was found only in second intervention (contamination p=0.001, wound discharge p=0.002 and superficial SSI p=0.004). This study concluded that behaviour modifications together with improved air flow system can reduce intra-operative contamination substantially. Purpose of the study was clearly defined and a good review of the current literature has given. Gap in current research was clearly presented and justification for the study had given. Sample size seems sufficient. It is reported that à ¢Ã¢â€š ¬Ã‚ ¦.bacterial cultures were taken during 207 random operationsà ¢Ã¢â€š ¬Ã‚ ¦ (p. 176), but no details of the sampling method used were provided. Details of interventions were given elaborately and results were discussed in detail. But only one table and two charts used to present it. The readers would have been more benefited if more tables were used to present the results. Discussions of the results were concise and findings were specific and satisfying the objective. No information on whether they received informed consent from the patients and approval form the ethical committee of the institution was missing. This arise a serious question about the ethics of this study. It is found that laminar airflow is more effective when use in conjunction with occlusive clothing (Charnley, 1969 cited in Sandiford and Skinner 2009). While in their recent study Miner et.al (2007) compared the effectiveness of laminar airflow system and body exhaust suits found that body exhaust suits are more effective than laminar flow system in reducing infection. For their study Miner et.al (2007) selected 411 hospitals which have submitted the claim for total knee surgery (TKR) for the year 2000 from four US States were surveyed to collect the details of use of laminar air flow system and body exhaust suits. Those hospitals which were fulfilled three criteria were included in this study. The inclusion criteria were 1) returned the survey instrument, 2) using laminar air flow system or body exhaust suits for infection control and 3) was evidence of at least one Medicare claim for TKR for the study period. Total 8288 TKRs performed in 256 hospitals between 1st January and 30th August 2000 were selected. Data on patient outcomes after total knee replacement (TKR) were collected from Medicare claims. The patients who underwent bilateral TKR were not included in this study and for those who underwent a second TKR during a separate hospitalisation during the study period, only the first procedure was included. International Classification of Disea ses, Ninth Revision (ICDS-9) codes was used to identify post-operative deep infection that needed additional operation. Hospitals were grouped as users or non-users for both laminar airflow and body exhaust suits. Users were defined as those who use any of these methods in more than 75% procedures and non-users were those use any methods less than 75%. The over-all 90-day incidence of deep infection, subsequent operation was found required only in 28 cases (that is 0.34%). Analysis found that the risk ratio for laminar airflow system was higher (1.57, 95% confidence interval 0.75-3.31) than body exhaust suits (0.75, 95% confidence interval 0.34-1.62). Study found that there were no significant differences in infection between hospitals that use specific either protective measure. Other than mentioning few studies researchers failed to provide any background of the research problem. Methods used for this study were explained concisely. Even though the sample size was large, limited number of events (28) were there to be observed. Analysis was based on this small number of events; this may have affected the result. Not many variables were included in this study, and researchers didnt mention how they controlled some possible confounders. Researchers were successful in identifying the advantages and limitations of the study. Results were properly presented in tables. Instead of expensive laminar air-flow system, installation of well-designed ventilation system is found beneficial. Scaltriti et.al (2007) conducted a study in Italy to examine effectiveness of well-designed ventilation system on air quality in operation theatre. They selected operation theatres of a newly built 300 beds community hospital which have ventilation system designed to achieve 15 complete outdoor air changes per hour and are equipped with 0.3  µm, 99.97% HEPA filters. All these satisfy the condition for a clean room as per ISO 7 standard. Passive samples of microbiological air counts were collected using Tripticase Soy Agar 90 mm plates left open thorough out the duration of the procedure. Active samples were also collected using a single state slit-type impactor. Total 82 microbiological samples were collected of which 69 were passive plates and 13 were active. Air dust was counted with a light-scattering particle analyser. Details of the surgery, number of people in the room, door opening rate and estimated total use of the electrocautery unit were also collected. It was found that there were positive correlations between particle contamination, surgical technique (higher risk from general conventional surgery), electrocauterization and operation length. Door opening rate was found negatively associated. Researchers suggest that this may because when theatre door open a turbulent air flow blows out of the operating room which may result decrease in the dust particles. No association was found between particle contamination and number of people present at the time of incision. Researchers suggest that human movement rather than human presence is the factor that determines airborne microbial contamination. It was found that average particle concentration in the theatres did not exceed the European ISO 14 644 standard limits for ISO 7 clean room, and so concluded that well-designed ventilation system is effective in limiting particulate contamination. Uncultivable or unidentifiable organisms can also be a reason for surgical site infections. It may be difficult to identify such organisms through standard culture techniques (Tunney 1998). Clarke et.al (2004) conducted a quantitative study to examine the effectiveness of ultra-clean (vertical laminar flow) theatres in preventing infections by unidentifiable organisms. They used the molecular technique, Polymerase Chain Reaction (PCR), to detect bacteria presence. Their study compared the wound contamination during primary total hip replacement (THR) performed in standard and ultra clean operation theatres. 20 patients underwent primary THR from 1999 to 2001 were recruited for this study. Patients with previous incidents of joint surgery or infection were excluded. The standard operation theatres had 20 air changes per hour and CFU count was 50 CFU/m3, while ultra-modern theatres had 530 air changes per hour and CFU count was 3 CFU/m3. For all surgeries same infection control precautions were used. Two specimens each of pericapsular tissues were collected from posterior joint capsule both at the beginning and at the end of the surgery (total 80 samples). Patients were given antibiotic prophylaxis after taking the first specimen. All these samples were underwent Gram stain and culture to detect bacterial colonies and Polymerase Chain Reaction (PCR) to detect bacterial DNA. Among the 20 specimens taken form the standard operation theatres at the beginning of the surgery only 3 were found positive with PCR, while from the ultra-clean theatres only 2 were found positive. None from both theatres found positive with culture. Samples from the standard theatres taken at the end of the surgery, 2 found positive by culture and 9 found positive by PCR. The contamination rate in the standard theatre at the end of the surgery found significantly greater than the beginning (p=0.04). Samples taken from the ultra-clean theatres, none was positive by culture while only 6 were positive by PCR. Statistical analysis found that contamination rate at the end of the surgery is not statistically different than the start (p=0.1). It was found that there were no statistically significant difference in overall contamination rate (p=0.3) between standard and ultra clean theatres. (I will add critique of this study here) NURSES ROLE IN INFECTION CONTROL Understanding the source of contamination in operating theatre and knowing the relationship between bacterial virulence, patient immune status and wound environment will help in improving the infection rates (Byrne et al 2007). Nurses are responsible to take a proactive role in ensuring safety of their patients. To improve patient outcome, it is necessary for the nurses to take lead role in environmental control and identifying hazards through environmental surveillance (Neil 2005). Non-adherence to the principle of asepsis by surgical team is identified as a significant risk factor of infections. Hectic movement of surgical team members in the operating room and presence of one or more visitors were also found as major causes of SSI (Beldi G 2009). Nurses and managers should emphasise on controlling factors like the traffic in theatre, limiting the number of staff and reinforcement of strict aseptic technique (Allen 2010). Creedon (2005) argues that infections can reduce up to one third if staffs follow best practice principles. For better outcome staffs needs additional education and positive reinforcement. Nurses have a vital role in the development, reviewing and approving of patient care policies regarding infection control. Nurses are not only responsible for practicing the aseptic techniques but also responsible for monitoring other staff for their adherence to policies. They are responsible for developing training programmes for members of staff. Educating the environmental services personnel like technicians, cleaners will not only improve their knowledge in patient care but also provide a sense of commitment in patient outcomes (Neil 2005). Perioperative nurses can contribute in research regarding theatre ventilation system through organised data collection and documenting evidences. Nurses can contribute in giving optimum and safe delivery of care in areas where environmental issues can put the patient at risk. Knowledge is changing fast, so it is important that staff must keep themselves up to date. Continues quality improvement is needed and it should be based on evidence based research and on-going assessment of information (Hughes 2009). CONCLUSION Reviews of current research shows that still there is a lack consensus on the effectiveness of laminar airflow in infection control. Studies include in this review has used either clinical outcomes (infection or reoperation rate) or intermediate outcomes (particle count or bacterial count) to evaluate the effectiveness of laminar flow. Kakwani et.al (2007) found that re-operation rate was lower in laminar airflow theatres but Brandt et.al (2008) found SSI rate was high in hospitals with laminar flow. Clarke et.al (2004) found that contamination was not significantly different in ultra clean theatres compared to standard theatres equipped enhanced ventilation system. Supporting this finding Scaltriti et.al (2007) found well designed ventilation system is effective in reducing contamination. Study by Knobben et.al (2006) found that combination of systemic and behavioural changes are required to prevent intra-operative contamination. Miner et.al (2007) found that there were no significant differences in infection between hospitals that use laminar airflow and body exhaust suits. From these studies it can be concluded that use of laminar airflow alone can guarantee infection prevention. Behavioural and other systemic changes are necessary to enhance the benefits of laminar airflow. Evidence shows that conventional theatres equipped with enhanced ventilation system can prevent infection effectively, this can be consider as an alternative for expensive as laminar flow system.

Sports Education Essay -- Education

Sports Education allows students to become more involved with the curriculum of the class. This is done by educating students to be players in the fullest sense, and to help them develop as competent, literate and enthusiastic sports people. This model should not be used in a regular physical education class because its take a lot of devotion and motivation on the students’ part to make this work. Offering a class as an elective that uses this model as the basis for their curriculum would be most beneficial. This way students that want to dedicate themselves to a class like this can do so by choice. Through participation, students will achieve the twelve objectives laid out by this model. Develop skills and fitness specific to particular sports. Appreciate and be able to execute strategic play in sports. Participate at a level appropriate to their stage of development. Share in the planning and administration of sport experiences. Provide responsible leadership. Work effectively within a group toward common goals. Appreciate the rituals and conventions that give particular sports their unique meanings. Develop the capacity to make reasoned decisions about sport issues. Develop and apply knowledge about umpiring, referring, and training. Decide voluntarily to become involved in after-school sports. The Sports Education model isn’t about students playing a game every day it’s much more than that. For students, the benefits of sport education participation include an increased investment in physical education, an increased level of learning in games units, and increased opportunities for potentially marginalized students. This model is broken down into six basic components that include seasons, team affiliation, formal comp... ...kouts during practices. Anyone can participate in a sport and be physically active. A student that experiences a sports education while get more of an understanding of the sport then someone who just plays the sport. This is because of the students are doing more than just playing the game. They set up the game; referee the game, and attempt to understand how every position is played. Utilizing core concepts of the interdisciplinary physical education model and the fitness education model one can ensure that they will leave with a well-rounded education. Works Cited Hastie, Peter.

Patient Education Plan

Pamela is 30 years old and a married Filipina with a two-year-old daughter. She was born in the Philippines and came to the United States at age 13. She has a high school diploma and she attended Cal Poly Pomona and received her degree in Electrical Engineering. She works Monday thru Friday at least eight to nine hours a day and still takes work home. When Pamela was 16 years old, she had an appendectomy. She enjoys drinking alcohol every week with her friends during happy hour since she was 21 years old. Otherwise she has no other significant medical istory. Her family history is very significant especially from maternal grandmother and grandfather who passed way with diabetes and paternal grandmother who passed away with lung cancer and paternal grandfather who passed away with brain aneurysm. Her mother currently has high blood pressure and her father has nothing significant going right now. Just about a few days ago Pamela showed symptoms of abdominal pain and projectile vomiting that had her husband worried about her and took her straight to the emergency room. Her pancreatic enzymes were levated, her abdominal ultrasound and CT of the abdomen showed inflammation of her pancreas. She was then admitted for further evaluation. Introduction Pancreatitis is an inflammation of the pancreas. With pancreatitis, the pancreas becomes inflamed, edematous, hemorrhagic, and necrotic. The pancreas is a long, flat gland that is located behind the stomach towards the upper abdomen. The pancreas produces enzymes, which help regulate the way your body digest glucose. Chronic pancreatitis is the progressive destruction of he pancreas as characterized by permanent loss of endocrine and exocrine function. The patient usually has chronic pain. Most studies of the pathophysiology of chronic pancreatitis are performed with patients who drink alcohol as stated by Nair, Lawler & Miller (2007). The signs and symptoms for acute pancreatitis are upper abdominal pain, which could radiate to the back, you would feel worse after eating a meal and there will be nausea and vomiting. There will be tenderness when the abdomen is being touched. The signs and symptoms f chronic pancreatitis is also upper abdominal pain, weight loss, indigestion and oily and foul smelling stool. Complications of pancreatitis include breathing problems that could be due to the oxygen level is low in the blood, diabetes may occur since the pancreas is the organ that produces insulin, infection may occur and have the pancreas be vulnerable of bacteria, acute pancreatitis may lead to kidney failure which could lead to hemodialysis if it is not treated. Malnutrition could be another complication since the pancreas cannot break down the food because a few nzymes are being produced. If the chronic pancreatitis does not get treated and it’s still reoccurring it could lead to pancreatic cancer. Treatment for this disease is hospitalization to stabilize the patient. Having her not consume any food during her stay will help the pancreas recover fully. Once its in control then liquid diet and advancing the diet may be course of treatment. A nutritionist will be involved in her care. IV fluids will help her stay hydrated. Pain is another factor to this disease and pain medications will be prescribed. At discharge some alternative therapy might help alleviate the pain. As mentioned on WebMD Tylenol should be avoided (2011). Exercises, yoga and meditation might be of good help to distract her. It can’t treat what she has but it could keep her comfortable. Age and Development/Educational Need In Erickson’s developmental theory Pamela is a young adult in Erickson’s that is Intimacy and Isolation. As long you have her trust in you, I believe using direct measurement as the approach of her method of learning. Just observing her behavior can help me distinguish hether or not she will be compliant. But during our session I noticed that she is willing and eager to learn and get well soon and she has shown that she is willing to be involved with her treatment. She has verbalized her understanding of what she needs to do once she goes home. Effect on Quality of Life Pamela would have to change her life style as she recovers from being diagnosed with Pancreatitis. She has to realize that whatever she has been doing on a daily basis would have to change. Her drinking of beer during happy hour every week has to stop. She’s not a smoker, hich is great. She has to drink lots of fluids and eat less fat on her diet. She would have to eat more fruits and vegetables, consume more whole grains and water. Perceived Challenges Pamela has always enjoyed her social life in going out with her friends to happy hour every week. Having to let that go might be a little difficult, being that she has always been going out ritually since she was 21 years of age. She is considered to be a very busy person that she uses alcohol to relieve her stress. So having her to give alcohol might be somewhat of a challenge. Eventually, with the support of her family and her husband especially might help her get through this stride. I see a person who is willing and get better not just for herself but for her daughter. Summary Teaching Pamela has been an experience. She showed to be very knowledgeable and very receptive. She asked questions that were relevant to her condition and since she asked shows me that she interested in getting better. She is willing to receive the help that she needs. She has verbalized her understanding and will call her physician if any of the symptoms reoccur.

The Revengers Tragedy a Play by Brain Gibbons

The Revengers Tragedy a Play by Brain Gibbons Literary work is a reflection of what is happening in the society. Authors normally voice their opinions about issues affecting the society through various themes. These themes are closely linked together through analysis of a character’s actions.Advertising We will write a custom essay sample on â€Å"The Revenger’s Tragedy† a Play by Brain Gibbons specifically for you for only $16.05 $11/page Learn More In the contemporary society, introduction of literature research has extensively increased the volume of literature in every topic of interest researchers may be interested in especially in use of expression tools such as metaphors to present a symbolic view that a character display in a play or a book. As a matter of fact, irrespective of the level of knowledge and understanding of research facets, literature versions are inclusive of literature tools such as metaphors. Literature comparison is about enjoying the phrases, feeling the n arrator’s words in action, imagining, and placing oneself in the writer’s shoes. Writings with consistent assumptions and symbolic insinuation add comprehensiveness to sentence structures or phrases with hidden meaning. The play, â€Å"The Revenger’s Tragedy† by Brain Gibbons presents a violent and vivid portrait of ambition and unending lust in an Italian community. Specifically, this play typifies artistic cynicism and satire to present a picture of a revenge quest that culminates into unfounded tragedy for both parties. Thus, this analytical treatise attempts to explicitly prove that revenge is dehumanizing in the play. Specifically, the paper concentrates on the death of the King and his attitude and treatment of his mother. Across the paper, the analysis draws critical reflection on the events that culminate into revenge and their eventual results. Gibbons was successful in addressing hypocrisy that was dominant in the early century in the theme of r evenge desires. This theme forms the foundations upon which the society of this play was built. It resonates across generations since its influence is inherent. Revenge desires as a thematic touch on identity crisis, tradition, manipulation, and marriage. The play â€Å"The Revenger’s Tragedy† portrays deep decay in political and moral parameters of the society. Irrespective of social class, religious inclination, size of accumulated wealth, epoch inclination, and beauty, death kisses people equality every time it knocks on the door of its victim. The tragedy delves on love, life, and tyranny. As a matter of fact, the key antagonists and protagonists demise eventually. Interestingly, death is presented as a redeemer of what each character stands for. Specifically, Vindice forms the image of an avenger who links economic disparities and female chastity to plot a dehumanizing plot on the old irresponsible king. Thus, â€Å"the smallest advantage fattens wronged men† (Gibbons 1.2.98).Advertising Looking for essay on british literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More The king is morally bankrupt and very corrupt in dispensing his authority on the subjects. Irrespective of the position of a person, revenge is presented as a poisonous object that sweeps away both the antagonist and the ‘revenger’. Despite having been an ideal person at the beginning of his quest, Vindice incessant activity resorts to the very ideals he protested against in the process of fulfilling â€Å"that bald Madam Opportunity† (Gibbons 1.1.55). Reflectively, Vindice becomes the victim of moral decadence and follows the ill practices concocted by the nobility in the society. In the process of revenge, the dehumanizing acts of aimless killings, habitual lying, and irresponsibility replaces gentlemanly attributes that were associated with him. Revenge is a continuing inspiration to overtur n the wrongs that were committed by a third party. When internalized, though may appear fulfilling, the art of revenge inspires hatred and unreasonable response to stimuli. For instance, in the process of plotting a revenge on the King, Vindice climbs overboard and convinces his parent to resort to prostituting his only sister Castiza to complete the revenge plot. Reflectively, the journey towards revealing truth makes him adopt a ‘Machiavellian cynicism’ that undermines his quest. He states, â€Å"Thou hast no conscience; are we not revenged? Is there one enemy left alive amongst those† (Gibbons 108). In the end, Vindice loses his outstanding personality and replaces it with self righteousness that is characterized by distributing blames and hanger on innocent third parties. He claims â€Å"And therefore I’ll put on that knave for once†¦for to be hones is not be in the world† (Gibbons 1.1.93). Vindice can be described as an agent of his own do wnfall. In the end, just like the slain King, Vindice ends up dead while fulfilling the burning desire to avenge. Across the play, the same fate crowns Hippolito, Ambitioso, Lussurioso, and Supervacuo. Death is a natural thing, and despite the fact that it is a sad affair, it might be less hurting if someone dies a natural death. However, Vindice, Ambitioso and Spurio fail to redeem themselves from the consequences of revenge and ends up in an unending holocaust. Specifically, the moral weakness of Vindice is seen when his personal indignation on the manners of the court and corrupt system of the judiciary metamorphoses into a radical immorality of a crime he later commit. As a result, Vindice states â€Å"the foul practice hath turn’d itself on me† (Gibbons 5.2. 299-300). Death is a tragedy that is unexpected, and it is not pleasant at all. The ground as to why inhabitants do not appreciate death is because it causes emotional damage and pain.Advertising We wi ll write a custom essay sample on â€Å"The Revenger’s Tragedy† a Play by Brain Gibbons specifically for you for only $16.05 $11/page Learn More The bitterness and resentment of Vindice make his vows that â€Å"in the midst of all their joys they shall sigh blood† (Gibbons 5.2.22). In a twist of events, these words culminate into the tragic destiny of Vindice. Thus, revenge is dehumanizing since those plotting it resort opt for the murders as political expedients of convenience and stimulates cosmic disorders in the society. The play ends in the purges that horrify other characters. Vengeance becomes the only Pyrrhic victory to these characters obsessed with the tasks of fulfilling tasks that are pre-ordained. For instance, Vindice states, â€Å"I do repent but heaven hath pleas’d it so†¦that I must be their scourge and minister† (Gibbons 3.4.173). This arouses inhuman acts of indiscriminate revenge actions with ill motives. For instance, Middleton’s my inspiration towards revenge was to institute a revulsion arousing dramatic tool. Besides, Vindice idolized revenge and painted it with words like â€Å"sweet, delectable, rare, happy, and ravishing† (Gibbons 3.5.1). This arouses suspicion into the underlying motives which sends Vindice into a medieval vice. Thus, revenge cripples these characters with hatred that culminates into premeditated murder. As a result, revenge â€Å"throwne luck upon the forehead of our state (Gibbons 1.2.4). Moreover, the remedy of the court was an alternative resort that was exercised only when disputes happened. The judicial proceeding was intended to provide solutions to existing disputes. The court was responsible to handle injustice cases that had already happened in the society and reassure the mass of fairness and accountability. However, the King’s revenge motives completely defaced the functions of this court. In his bid for revenge and center po wer, the King neglected justice in the court. Revenge games compromises integrity of the parties involved. Reflectively, this happens due to the fact that some of the players are naà ¯ve, while others are indifferent. For instance, Vindice is unhappy at his parent’s inability to resist bribery. The mother states, â€Å"I blush to think what for your sake I’ll do† (Gibbons 2.1.24). In this aspect, revenge is dehumanizing in its characteristic of making parasites out of people, internalizing corruption, and being the engine that drives greed and unending lust for advancements in the social endeavors. All the characters in the revenge matrix have selfish and debased ambitions that inspire their urge to maintain the status quo irrespective of any collateral damage in the process. Interestingly, the Duke who should symbolize justice and moral authority asserts that â€Å"I’ll try them both upon their love and hate† (Gibbons 2.3.86).Advertising Looking for essay on british literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More In fact, Vindice’s reaction reveals an unfounded hatred, ignorance and blindness of high magnitude as they climaxed. In an ironic tone, Vindice retorts, â€Å"Pray heaven their blood may wash away all treason† (Gibbons 2.3. 98). The other revenging characters destroy Vindice as a survival tactic on realizing that he plans to destroy them. Justice was a notion that concerned duties and rights of people in this society. Justice was an interpersonal concept that sought to resolve conflict among people. Nevertheless, this was not to claim that inferior interests were suppressed. Justice aimed to sustain and build right behaviors while judicial court was responsible to deliver judgment among peoples. However, the rejection of justice by the King resulted in series of revenge plots that swept the morals and ethics of this society. Gibbons, Brian. The Revengers Tragedy, New York: Norton, 1967.

Brand Loyalty Depends On Brand Elements The WritePass Journal

Brand Loyalty Depends On Brand Elements Introduction Brand Loyalty Depends On Brand Elements IntroductionReferencesRelated Introduction A brand is a design, term, name, or any feature used to identify the products or services of a seller from the ones of other sellers in the market (Jacoby and Chestnut, 1978). Although there is a large body of research on brand loyalty in marketing literature, the relationship between brand loyalty and brand elements has not always been well documented or understood. In this essay, the contention of whether brand elements play a significant role in influencing the loyalty of consumers shall be raised. First, a definition of brand loyalty and brand elements will be outlined, followed by arguments for and against the claim that brand loyalty is dependent on brand elements. In so doing, this essay will draw on marketing and consumer behaviour literature as well as case studies from well-known brands to illustrate the arguments. Brand loyalty has been considered as the conscious or unconscious decision of a consumer to continually repurchase a brand (Keller, 2007).   Brand loyalty has always represented one of the top priorities for a brand. Brand giants such as Coca-Cola and Pepsi for example, frequently bring out brand loyalty promotions such as â€Å"My Coke Rewards† and â€Å"Pepsi Stuff† in order to retain its committed consumers (Dick and Basu, 1994). Conversely, brand elements refers to the different components that make up a brand. These can include both internal and external elements. Internal elements, for example, include brand personality and promise whilst external elements refer to associations, image and positioning of a brand. Building from these two key concepts, it may be argued that brand loyalty can only be achieved if a number of effective brand elements are firmly in place. Some have argued that external elements such as brand positioning are critical in cultivating trust between the consumers and the brand (McCole, 2004). Brand positioning refers to the aspects of the brand used in the specialization of the organization, its target market, the unique value of the company and the benefits a consumer would acquire from buying its products and services.   Brand positioning also expends effort in differentiating a company over competitors. It is therefore possible that it is only once a consumer acquires greater knowledge and clarity of a company’s specialization, unique value and potential benefits, that he/she will be more likely to repurchase the product and therefore ensuring brand loyalty (Aaker, 1995). In a similar vein, the element of brand promise can also be seen to play a major role i n brand loyalty. Brand promise refers to the particular element that consumers expect to be delivered by the company each time the consumer purchases an item and/or service. By this definition, brand promise is a multi-level element as it involves factors such as expectation, interaction of employees to meet these outcomes and delivery (Cowley, 1991). If each of these elements is in place, consumers are much more likely to express loyalty to the brand. An additional argument that supports the claim that brand loyalty is dependent on brand elements can be drawn from examining one of the internal elements; brand personality. Every brand can be said to carry its own unique brand personality. Brand personality personifies the brand in terms of human characteristics and traits (Kapferer, 2008; Aaker, 1995). A brand without personality and warmth, for example, is likely to garner zero loyalty from consumers and will be much more sensitive to prices (Uncles Goodhardt, 2004). A positive and distinctive brand personality on the other hand, is much more likely to elicit favourable outcomes such as increased preference, usage and loyalty (Aaker, 1997). There is a well-established body of literature that highlights that a clear brand personality not only enhances brand preference but improves loyalty (Kressman et al 2006) but also allows consumers to express and project their ideal selves to others (Belk, 1988). The brand becomes an extension of the consumer’s self. Brand personality, can therefore be shown to play a critical role in allowing consumers to connect on a personal level with a brand and hence be more likely to leave a long-lasting positive imprint that leads to repurchase and gradually builds up brand loyalty. However, it may also be argued that brand loyalty can also be build up, independent of brand elements. This argument focuses on the importance of strategy, rather than brand elements. An example to illustrate the importance of strategy can be seen from the changes that have occurred in marketing over the last decade. For example, due to the advances of web 2.0 and social networks, traditional marketing practices of examining consumer trends, conducting focus groups and assessing demographics have been supplemented by social media marketing on social networks, videos and blogs. The number of companies and businesses leveraging the social network platform to connect with consumers via fan pages is increasing every day and global companies such as Coca-Cola, Mercedes-Benz, Starbucks, Disney, New York Times, Red Bull, to name a few, are now prominent fixtures on social networks. Coca-Cola, for example, allowed two of its fans who created the brand’s Facebook fan page to continue t o manage it on Facebook. It is not surprising therefore, that Coca-Cola has now amassed over thirty-four million Likes worldwide. Starbucks has similarly demonstrated the importance of a social media marketing strategy in the creation of â€Å"My Starbucks Idea†, a site that allows consumers to submit suggestions that are reviewed and often implemented. As market research has indicated that more than 80% of individuals who â€Å"Like† a brand or product on Facebook are loyal consumers (DDB Worldwide, 2010), new strategies of social media marketing and innovative fan pages are increasingly becoming important in the success of a brand. Elements such as brand image and personality may have been important ten years ago, but brand loyalty can now be independent. One may also adopt a perspective that unites the opposing arguments and postulates that brand elements are important, but not requirements of brand loyalty. Instead, a number of other factors are important such as in the case of â€Å"Spurious Loyalty† in which customers may repurchase a brand due to situational constraints or out of convenience. Moreover, it has also been suggested that brand loyalty contains a considerable degree of pre-dispositional commitment towards a brand that has nothing to do with the brand elements (Punniyamoorthy and Raj 2007). As there are no specific theories and approaches that address the question of brand loyalty and brand elements, it is difficult to provide a definitive answer. However, over the course of the essay, it has become apparent that brand elements do play a pivotal role in brand loyalty and that consumers are likely to repurchase a brand because they perceive the brand to serve their product needs by offering the right features of the product, price, quality and image as well. However, it has also become clear that brand loyalty is grossly influenced by decisions that take place independent of brand elements. In conclusion, a balance between both arguments would definitely be most effective for addressing the claim. In the future, a greater body of work is necessary to aid researchers, scholars and marketers to come closer to understanding the multi-dimensional nature of brand loyalty. References Aaker, D. 1995.

Gender Disparities Within Indian Families

Gender Disparities Within Indian Families Free Online Research Papers Family is the only place where the children learn to grow up, socialize themselves to quickly adopt the culture, mores, values, and customs and family is perhaps, the unprotected place where gendered socialization takes place. In spite of modernity, in the 21st century, gendered socialization is still prevalent in the rural India and the family members do not cease to bridge the disparity among boys and girls. The growing India lags behind because of the disparities which half the population faces, face to face. Gender seems to be omnipresent, spreading roots day in and day out almost in every corner of the country. However, it is most practiced in rural areas. According to a sociologist, for many people, the family provides a vital source of solace and comfort, love and companionship. Yet, it can also be a locus for exploitation, loneliness and profound inequality. The main function of a family is to engage in the process of socialization, where the young members of the family, especially, little children, learn the basic tenets of the culture in which they are born. Besides this, it also helps in personality stabilization and helps to tie up the relations among the members of t he family. The family, therefore, performs as many tasks to unite the members of the family and inculcates the young members to behave or confront to the basic norms of that particular society. But, it is a matter of disgrace that just like the workplace or for that matter anywhere outside the homes; family too takes part in the formation of gendered socialization. A study shows that children in almost all families in India face discrimination. In rural families members are of a view that a girl child should behave more accurately than a boy child. A boy is expected to shout and scream for small matters, it is not an attribute of a girl child to raise her eyebrows in cheap matters; she ought to endure without being impatient. Why is this that while the boys study in their capacious reading rooms, the tired girl desperately desires to have a nap but is disallowed, albeit indirectly, to have it and is expected to carry on with the ladies job within the four corners of the dark and congested kitchen, possibly for hours. My personal meet with a family in Bamangama, a village in Bihar, perhaps occupies an important stand in the discussions. When asked the mother of the girl whether her daughter goes to school or not; she claimed that girls are to stay and help their mothers in homes, not to roam around the villages with a B.Com/ LL.B Degree against their names. No one denies educating their daughters but Madhyamik Pariksha is the limit, an H.S. (+10) to the maximum. Pockets of girls bulging with Degrees look ugly and both are incompatible. They are to learn how to cleanse the infected utensils, how to make appreciable dinner, how to wipe clothes, so that it helps her in future when she goes to her husband’s home. When I went to have a short discussion with the only boy child of that particular family, I was stopped doing so, and for a good reason. The mother quietly whispered that his exams are going on and that we do not like the disturbance of anyone when he is reading. Le him read, said the mother lacking required hesitation. This was an empirical study conducted by me to look behind the social structures where the view that ‘right to equality’ is dominant in India, is viewed with closed eyes. The conception that boys are or should be treated as boys is based on untrue generalizations. Today, girls are equally better and they have in fact proved that time to time, in varied fields (Sunita Williams, Kalpana chawla, Kiran Bedi, Sania Mirza etc. to cite a few Indian elite damsels). They are destitute of opportunities. Provide them. A girl is not limited to homes, the sky is their playground, stars their friends. But there always lied a demarcation between the types of things which boys could do and girls could, but were not to. In India particularly we find that during socialization girls are socialized in such a manner as to make them a girl. They are transformed to a girl from a human being. The saying corroborates this fact; Woman is not born, but made. They are to care for the elders of the family. Girls should not hang out with their friends late at night unlike boys, who are usually independent when comes to paint the town red in the absence of sun. Robin Lakoff has sug gested that in the course of socialization, girls are taught to speak in feminine ways, as opposed to talking roughly like boys. As children, girls are encouraged to be little ladies, who do not scream as vociferously as boys, and they are chastised more severely for throwing tantrums or showing temper. High spirits are expected and therefore tolerated from boys, whereas docility and resignation are the corresponding traits expected by little girls. People tend to excuse a show of temper from a boy where they would not excuse an identical tirade from a girl. Girls are allowed to fuss and complain, but only boys can bellow in a rage, says Robin. Limitations to opportunity for girls are as innumerable as the shining stars in the sky, the more you delve into, the more you confuse yourself. The most commonly accepted balk for girls to spread their wings is technology. In feminist analysis technologies are often described as ‘toys for the boys’. Marriage fits in as the second reason for ‘glass ceiling’ i.e. limitations for woman in the sphere of work. Women migrate with their husbands because of the changing nature of their jobs. Women prefer migrating with their husband to working in their hometowns, as usual. Thus, women stays at home, as a doting mother, and if educated (instance is extremely subtle) kills their education within themselves at the cost of their children and migratory husbands.

This paper gives acritical analysis of artwork detailing its author, key significance, how it conforms to culture, style, and color of production. It also contains the visual analysis of its composition and depth of painting. Evidently, the oil painting was executed based on quality guidelines of fine artwork. The object is clearly presented, well-shaped, painted with good color, and composition. It is also clear and in good shape and size, that enables effective view and conceptualization. That is, the object has a clear view including other subsidiary objects in its surrounding that include the human beings (Lehrer 140). Particularly, the painting of the rainy day is balanced as they are placed at strategic areas that ensure balancing of the painting material without learning towards the left or right side. The size of the painting and space also enables viewers to see the paintings clearly thereby execute accurate differentiations. The artist utilized the space accurately, optimally to ensure that the objects are balanced effectively, colored appropriately, and presentation is done in good sizes.

This is apparent as the picture depicts the place de Dublin that is located at a road intersection point eastwards of Gare Saint-lazare. From the painting, one can see buildings, couples walking and people moving with umbrellas. Its main theme is to enlighten individuals about the cultural practices in urban areas including how people move about

The politics of mass consumption in postwar America by Lizabeth Cohen, Essay

The politics of mass consumption in postwar America by Lizabeth Cohen, - Essay Example Explain how the consumer economy, society, and culture during the World War II era affected women and African Americans and how consumerism in the wartime years provided opportunities for both of these groups to claim greater social and political power as â€Å"citizen consumers. Soon after the World War II, the American administration had adopted an effectuate strategy to reconstruct their economy by promoting and expanding mass consumption. Those who were at the helm of affairs took prosperity of Americans, as a central point of their plan. In their thoughts, the demand driven economy not only provide an opportunity for effective recovery but rekindled hopes in Americans for becoming part of an egalitarian society and to raise their heads being a true democratic nation. The idea of mass consumption provided American citizens to live in an ideal situation than before with equal footings with the neighbors (Cohen, 64). The above move was not accidental. It co relates with the histor ical era of 60s and 70s. At that time, the diversified segments of society comprised of African American origin, women, adults and the old citizens began to assess themselves within the ambit of identity politics. Here, the people’s affiliation with specific community defined their cultural awareness and motivation for a consolidated action. If we look back to the era of 60s, we find that those market managers, who failed to respond to the market demands in terms of innovative products, soon disappeared. Mr. Haley, Vice President and corporate researcher very rightly pointed out "it is easier to take advantage of market segments in vogue than to attempt to create new ones" (Cohen. 68) With the advent of new innovative deals and the ending of World War II, sizeable American Consumers got to know their rights as an individual consumer which was instrumental in promoting the generalized goods. In his book Cohen introduced mass consumption philosophy into four parts. In Part I, s he elaborately discussed the "Origins of the Postwar Consumers' Republic,† concerning 30s and 40s era, when a concept of citizen consumer was coined that emanates from women and African-Americans. The said categories accept it a way of life. They consider it  to be  a safer and equitable market place. In the second part namely "The Birth of a Consumers' Republic," wherein she specifically discussed the role of Consumers? She hailed the patriotism of American nation since they fulfilled their obligations by promoting consumerism as a safe passage to economic equality and the political independence. Cohen identifies how consumer related policies helped the consumers to underwrite in terms of GI Bill and the tax code, which benefited the white middle class males segment greatly at the cost of discriminating other stakeholders with particular reference to women and the African Americans origin (Cohen, 85). She also discussed in her book the existing gap between the promise and the reality with regard to the rights of Consumer, instrumental to ignite civil rights movement. The increasing demand of blacks for public accommodation, stores, theaters and restaurants against the backdrop of black access to house themselves in public accommodation e.g. downtown stores, movie theaters, and restaurants can not be ignored. Above mentioned sites of consumption, overshadowed by the privatized new commercial avenues that comes to surface in suburban America. In part III entitled "The Landscape of Mass Consumption," Cohen apprised its readers that how the suburban America queued racial and income lines in accordance with the study of New Jersey State. For him suburban shopping malls not inclined to adopt the model of urban downtowns. In the last part of discussion that drives out from â€Å"The Political Culture of Mass Consumption," shows how the market trend and the national politics could effectively be dealt with the issues of reinforcement and simplification to cope with after war trends.

What does it mean to say of a piece of instrumental music that it has Essay

What does it mean to say of a piece of instrumental music that it has certain emotional qualities - Essay Example A musical instrument being an expression of emotion in a persona or number of characters, the listener is right to imagine, in accordance with the nature and development of the music, a persona undergoing an emotion or series of emotions, or a number of characters doing so. Hence, it can be said that the idea that the emotional qualities of music are such that they are liable to induce an emotional response in the listener. This liability in a musical instrument need not be thought of as a disposition of the emotional quality of a piece of music to arouse a corresponding emotion in listeners who perceive the quality. When it comes to the use of musical instruments, a very great deal depends on the correct conception of the emotions. A common view is the so-called cognitive theory of the emotions, which is adhered to by the principal of philosophical sceptic about music’s ability to arouse emotions of the garden variety. The cognitive theory exists in many forms, which differ in both the number and nature of the elements of which emotions are said to be composed. What is definitive of the theory is that it represents each type of emotion as being defined by a particular kind of proposition or thought plus some combinations of bodily sensations, he donic tones, and feelings. Therefore, when the emotion is experienced, prompted by something perceived, imagined, or thought about, it will have a real or imaginary object upon which it is directed, the emotion being about this intentional object (Lippman, 46). Scepticism about pure instrumental music’s ability to stimulate extra-musical emotions in a listener in an artistically relevant manner arises at once from the fact that music is a non-representational form of art, presenting no scenes or actions that the listener might respond to emotionally as the viewer of a film or the reader of a novel might. Although instrumental music is extremely limited in its imitative capacity, it may nevertheless produce all the effects of imitation. Instrumental music can excite different dispositions, but it cannot imitate them. Furthermore, instrumental music has certain instrumental intrinsic qualities of an emotional nature and that these qualities excite corresponding feelings in the listener. Instrumental music, it is claimed, operates at the emotional level by some systems of resemblances. Such psychological manifestations of emotional state are an extremely important stimulus in interpersonal interaction; sensitivity to them and interpretation of them are essential social skills. However, to explain emotional response to instrumental music as occurring solely in terms of iconic resemblances between features of the music and physical expressions of emotion, is under-representing the complexity of the response to this aspect of the music. Therefore, whatever the philosophical or semantic concerns, the implication of the much preceding evidence remains that we process emotion in musical sounds, whether vocal or instrumental, in the same way as vocalizations of affective state. The acoustic signals used in the production and perception of emotion in instrumental music appear to be the same as those used in vocal utterances, such as high intensity and harsh timbre for anger, low intensity and tempo and slow vibrato for sadness, whilst variation in timing and intensity typifies fear (Cochrane, Fantini & Scherer, 58) .

Organisational Theory (Business Management) Essay

Organisational Theory (Business Management) - Essay Example The organizations also require their employees to be technological savvy so that they can cope up with rapidly evolving technologically driven environment. The future of organization is thus expected to be very different in terms of its operations form the current due to rapidly changing technological driven environment. Modernism (Ontology: Objectivism) This theory focuses on organization as an independent objective thus taking a positive approach in generating knowledge which is vital in increasing efficiency. This theory focuses on an organization as a community sustained through human relationships and use of subjective ontology in most of the everyday activities. This implies that instead of man treat organizations as webs of meaning that are jointly created and not as objects to be measured and analysed hence exploring meaning to realities made possible by those who participate in them. Post modernism generates health scepticism towards dominant theory hence licensing individua ls to try something different most of the time (Melaney, 2001). The organization culture is the collection of values and norms that people in a company share thus controlling the way in which individuals interact with one another in their day to day activities. The values represent beliefs and ideas especially in the organization goals which workers pursue thus achieving them in a particular pattern and behaviour which often differ from one person to another. These values over time develop norms and guidelines together with expectations that determine the behaviour of employees which in turn affects the behaviour of the management towards them. The organizational culture in most cases spans form the top management downwards thereby acting as a control mechanism which shapes the behaviour of the employees at different levels of management thus establishing organization behaviour. This promotes the employees effectiveness through mutual understanding between individuals and groups wit h the ultimate goal of achieving the best results for the company. This provides a continuous system in which employees work harmoniously thus controlling themselves while adhering to the norms of the company. This theory also focuses on how organization members make meaning and role that determine the direction of workplace. The art of moving cultural symbols is predominantly made by the press and the politicians thus changes the meaning of situations and locations in which they occur. The postmodern cultural studies often go beyond fragmentation assumption by asserting that reality is an illusion that aims to suppress and marginalize those who do not accept and support the dominant view. According to this theory, organization culture is just one more from form those in power to mask their manipulation and control of others thus leading to destructions (Hatch & Cunliffe, 2006). Critical theory (Epistemology) This theory is an approach developed by Frankfurt school in Germany and it holds that every society is totality in which each feature is essentially connected with others constituted by forms of beliefs and understanding in the society. The theory argues that atomism and objectivism are false, the epistemology of critical theory combines historical materialism, Freudian

The Son Also Rises - Essay Example Paris, which had been his home previously, is no longer suitable for him. The city’s pace and vibrancy is something he cannot keep up with. The city also reminded him of his lover Brett, to whom he no longer can make love due to his physical impotency. Hence, he decides to go to the more laid back and picturesque town of Burguete. The slower pace of life here and the cordial nature of the town’s inhabitants enable him to start the process of recuperation. More importantly, this place enables Barnes to impose order on his life and make an independent living. He is able to live life on his own terms and also maintain dignity. But the story of Jake Barnes’ confrontation with his physical and emotional marring does not end there, for his discontent with the sedate and lonely existence in Burguete forces him to continue his search for inner peace. This peace proves elusive and not until the end of the story does Jake Barnes able to somehow reconcile with his reality. It is only when he moves to San Sebastian, does Barnes achieve some sort of stability and harmony, albeit with an element of resignation too. Hence, Jake Barnes typifies the Hemingway Hero in The Sun Also Rises. The other important character in the novel is that of the popular Bull fighter Pedro Romero, whom Jake admires very much. In fact, Jake takes comfort and pride from the successes of Romero. Hemingway is implying that Jake Barnes compensates for his inadequacies through the accomplishments of Pedro Romero. The qualities that define Jake Barnes also differ sharply from the attributes of a typical Hemingway Code Hero. As opposed to a Hemingway Hero, the Code Hero, though dealt harshly by the circumstances of life, does not submit himself to its constraints. To the contrary, he refuses to be defeated by life and remains tough and optimistic. Romero is also shown to display humility and dedication to his craft of Bull

Pintex Organics London Ltd - Assignment Example The first problem emerged when the company entered into a contract with Mixurs Ltd to supply it with equipment, but the equipment was found not to be compatible with the installations in the company’s premises, hence, cancellation of the contract. The second major problem concerning the contracts occurred when the negotiations for a contract under which the company would provide catering services to members of the International Olympics Committee collapsed because the parties could not agree on the contract terms. As a result, the company lost the contract and the financial benefits that could have arisen out of it. Therefore, the company needs to ensure that its interests are in tandem with the English contract law. Also, there is need for the company to review its terms of agreement to avoid a situation such as that of Miah where the former director of the company enters into contract with the immediate potential client of the company. In regard to the cancellation of contra ct offered to Mixurs Ltd, it was in order as the company was exercising the right to cancel a contract stated on the Cancellation of Contracts made in a Consumer’s Home or Place of Work Regulations 2008 Act Article 8(1-6) (The National Archives, 2008). However, it would be advisable that the company should exercise caution when entering in contract with other companies when intending to purchase. This will be crucial in ensuring that the company does not incur losses or get substandard equipments (Taylor, 2009, p. 101). Concerning the second scenario where the negotiations between the company and the International Olympics Committee collapsed, it is important that such occurrences should be avoided or minimized in the future. It is no doubt that such a contract would have not only offer the company financial benefits but boost its quest to becoming the leading provider of catering services in the forthcoming 2012 Olympic games. Losing such a contract was not desirable for the company’s business prospects. The company should know that it should not necessarily bid the adequate price but, rather, the consideration should be of sufficient value in the eyes of the law (Keenan, 2006, p. 29). As the Chappell & Co Ltd v Nestle Co Ltd (1960) AC 87 showed, the offeror needs to make a consideration that is sufficient and not necessarily adequate (Sealy and Worthington 2010, p. 45). Applying this in the contract might not have afforded Pedro’s company the financial rewards they intended but would have provided them with the opportunity to maintain International Olympic Committee as a client for future services, especially in the forthcoming 2012 Olympics games, hence, more revenues in the future. Apart from that, hosting of such high profile clients would have boosted the reputation of the company thus attracting more clients which will translate to more revenues. It can be argued strongly that Miah was not comfortable with the contract terms of the POL Ltd to International Olympics Committee which he may have seen to cost the company both the revenues and the reputation. He was, thus, convinced that it was more worth to resign from the company’s directorship and open his own restaurant in order to gain benefit from providing services to International Olympics Committee both at that time and in the future. As noted, the company’s other problem arise from the terms of agreement for the

Recommended procedures for improvement Essay Example for Free

Recommended procedures for improvement Essay As systems turn out to be more programmed and mechanized, those in charge of information system have a tendency to consider that more power will construct their processes better organized. In pulling manufacturing and design en route for computerization, the inclination is to provide as much power as probable to the mechanism and leave the lingering job tasks at hand. This automation viewpoint reduces the information and perceptive capacities of workers and pushes them to dislike the technology. Premises in the field of information system management are significant whether one’s orientation is in the direction of research or practice (Tapscott, 3). The responsibility of an organization is to help out in withdrawing the complication of the world and explaining and predicting proceedings. Given the information that the purpose of information system management management is to lessen the convolution of the empirical world by means of technology can benefit from sound improvement. While the complexity of the information system plan will vary based on the size of the district, it has to include a mission statement and rational, quantifiable goals and objectives that can be attained, in most cases, with obtainable resources. The Alachua’s budget also has to reflect the financial obligation to major technology initiatives included in the plan. Additionally, the planning process must include proceedings that allow decision makers to gauge the benefits of investments in information system and abandon or alter failed strategies for more triumphant ones. Methods of making a Web site secure from hackers It is not that software has turned out to be less protected, and it’s not almost certainly because of potential attackers having increased in number. The reason that hackers are more common is likely because many people do not know how to protect their Web sites. To make a website free from hackers, simply: (1) know your enemy, (2) create ‘strong’ passwords, (3) use good software, (4) update recurrently, (5) use a hardware server-side firewall and (6) facilitate WPA or WEP encryption on wireless network connections. Digital Signature Digital signatures are just like written signatures these are used to provide verification of the related input, typically called a ‘message’ (may be anything) a message sent in a more complicated cryptographic protocol or from an electronic mail to a contract. In cryptography, a digital signature or is a kind of asymmetric cryptography used to reproduce the security properties of a signature in digital than in a written form. Digital signatures usually give two algorithms one for signing that involves a user’s secret (private key), and one for validating signatures that involves user’s public key and the output of the signature method is known as the digital signature. â€Å"Terms and Conditions† or â€Å"Conditions of Use† -Websites and its related services are administered by the Terms and Conditions of Use, and the constant access to websites and its services is put through the user’s agreement to be bound by the Terms and Conditions of Use, as they may alter occasionally. Terms and Conditions of Use is a provision placed on a website notifying users regarding how the website deals with a user’s rights and responsibilities. Some websites characterize their Terms and Conditions of Use allowing users to routinely assess its services offered. If a user does not agree to Terms and Conditions of Use, a user may not use the website or its services. Plans of Alachua County in information system must state who is responsible for implementing and updating the technology plan. The Alachua County District’s technology plan must includes information on individual needs, equitable resource allocation, cost-effective acquisitions, technology funding, infrastructure and networking issues, technology-related professional development, support needs, and information management and delivery. On the other hand, the district’s does not make use of this best practice for the reason that the plan is not complete, is not based on a valid needs assessment, and is not evaluated and updated in a scheduled manner. The constituency should guarantee that the goals listed in the plan are detailed, quantifiable, manageable, rational, and time-bounded. The county also should ensure that the plan is monitored and updated based on valid data related to the district’s technology needs, skills, usage, and fluency levels among district employees. Strategies in the county’s strategic plan relate to technology and are considered the goals for the technology plan. In the district technology plan, the objectives are ambiguous (e. g. : guarantee, renovate, generate, etc.). Few of the objectives are assessable and are not based on detailed standards, making it complicated to document whether the objective was acquired. Additionally, it is imperative to note down that all decision-making in information system management is derived from some embedded premise. For the reason that the consequences by means of vague assumption information system management are better for all assumptions that give understanding may perhaps have even greater importance to all organizations (Tenkasi, 27). If one relies barely on the capability to forecast events devoid of understanding them, there is a greater prospective for making underprivileged, or at least unproductive decisions. The recommendations given are good examples of research that has hardened models of managing information systems in local areas and even in worldwide perspective. Yet there is still a need for more investigations to be able to accomplish a more constructive course of action in business information technology management. Information technology systems and management necessitate of a solid abstract establishment to direct both practice and research. Even though many of the recommendations being proposed by scholars and scientists in this field may possibly be compelling prescriptions for those who are on the lookout for something further than unsystematic information management, unless information management turns out to be strongly stranded in theories of organization.

Causes of Luminescence and Chemiluminescence

Causes of Luminescence and Chemiluminescence 1.1. Luminescence Phenomena Luminescence is the phenomenon of emission of electromagnetic radiation in excess of thermal radiation. The radiation is usually in the visible region of the electromagnetic spectrum, however, since the same basic processes may yield infrared or ultra violet radiation. Luminescence is observed with all phases of matter: gases, liquids and solids both organic and inorganic[1]. Luminescence is an umbrella term for those kinds of events where light emission is not the result of high temperature. In fact with increasing temperature the competing nonradiative de – excitation processes become more probable and the intensity of the luminescent emission decreases. Luminescence in living organisms has been reported as far back as 1500 BC. In Chinese literature, the best known examples being the emission of light from fireflies and glow – worms[2, 3]. 1.1.1Types of Luminescence Classification according to the means by which energy is supplied to excite the luminescent molecule[4-8].Table 1.1 Table (1-1):- Different types of luminescence phenomena Excitation source Luminescence type Produced from irradiation Absorption of Uv-vis or near IR radiation. (Conversion of light energy to chemical energy). Photoluminescence Emission produced from irradiation of ÃŽ ² particles. Cathodoluminescence Emission produced from irradiation of ÃŽ ± particle. Anodoluminescence Radiation-induced chemical excitation (irradiation of ÃŽ ³ particles. Radiodoluminescence Produced from heating. Emission from incandescent solids Candoluminescence Caused by solid subjected to mild heating. Thermoluminescence Flame-excited metal atoms Pyroluminescence Produced from structural rearrangements in solids Emission from shaking, rubbing, or crushing crystals. Triboluminescence Emission from crystallization. Crystalloluminescence Excitation induced from dissolution of an irradiated or other energy-donating solid. Lyoluminescence Produced from electrical phenomena. Radiative recombination of electrons and holes in material (emission from electrical discharge) Electroluminescence Emission during electrolysis Galvanoluminescence Excitation of compounds by ultra-sonication. Sonoluminescence Emission from fractional charge separation at the crystal surface. Piezoluminescence Produced from chemical reactions Emission from luminous organisms. Bioluminescence Chemical excitation of compounds. Chemiluminescence 1.2. Chemiluminescence The term chemiluminescence (CL.) was first coined by Eilhardt Weidman in 1888. Chemiluminescence is defined as the production of electromagnetic radiation observed when a chemical reaction yields an electronically excited intermediate or product. CL-reactions emit light of varying degrees of intensity and lifetime. With colors that spare the visible spectrum [9-11]. Analytically, the CL-reactions are attractive due to: excellent detection limits results from the absence of source of noise and scattering, suitable to both batch and flow techniques highly sensitive, determinable over a wide range of concentrations, easy to operate, simplicity, absence of unwanted background so the only background signal is that of the PMT dark current and no excitation source or optical filters are required as compared to other optical or photo luminescence methods [12, 13]. However, some disadvantages are to be considered as well; A chemiluminescence reagent may yield significant emission not just for one unique analyte i.e. a lack of selectivity may occur. Moreover, chemiluminescence emission intensities are sensitive to a variety of environmental factors such as temperature, solvent, ionic strength, pH and other species present in the system. As a result, a separation condition (HPLC, capillary electrophoresis (CE), may not always match the optimum CL-emission conditions. Third, as the emission intensity from a CL-reaction varies with time,light flash composed of signal increase after reagent mixing, passing through a maximum, then decreasing back to the base – line, thus the CL- emission versus time profile differs from one compound to another and care has to be taken to detect the signal in the flowing stream during strictly defined periods [14].chemiluminescence technique is versatile for determination of a wide variety of species that can participate in the CL-reaction such as; CL-substrates or CL-precursors responsible for the excited state [15], the necessary reagent for the CL-reactions (usually an oxidant) [16] , some species that enhance the rate or sensitivity of the CL-reaction[17] ,activators such as catalysts (enzymes[18] or metal ions[19] CL. analysis found a wide application not only in the organic technology, medicine, food testing, but also in environmental monitoring and material science [20-24]. CL-reactions can be coupled as a detection technique [25] in chromatography [26, 27], capillary electrophoresis [28-30], or immunoassay, providing qualitative and / or quantitative information [31, 32]. 1.2.1. Mechanisms of Chemiluminescence Reaction Figure (1-2) shows the types of the CL-reaction mechanisms. In general CL-reactions can be generated by two basis mechanisms: Figure (1-2):- Types of CL-reactions. P, product; F, fluorescing substance Direct CL-reactions: a substrate (A) and an oxidant (B) in the presence of cofactors react to form an intermediate product in an electronically excited state which relaxes to the ground state with a photon emission. The catalyst is an enzyme or metal ions, reduces the activation energy and provides an adequate environment for producing high CL-efficiency out of the process.Cofactors sometimes are necessary to convert one or more of the substrates into a form capable of reacting and interacting with the catalyst,or to provide an efficient leaving group if bond cleavage is required to produce the excited emitter [33]. An alternative for compounds producing ultra-weak CL-emission is: Indirect or sensitized CL reactions: Since not all excited states of CL-reactions products are effective â€Å"emitters† in any case, thus the excited state energy can be transferred to an â€Å" effective â€Å" flourophore added to the system, in –order to increase the CL-intensity substantially . The most salient asset of chemical excitation is the low background noise involved, which results in very low detection limits (in the sub femtomole of region) [34,35]. Enhanced CL- reactions (ECL): describes the phenomenon which has been observed in a wide range of chemi and bioluminescence reactions. Enhancement of light emission from the luminol-hydrogen peroxide reaction at alkaline pH has been achieved by the addition of various organic compounds generally containing oxonium group. Enhancement of CL. Reaction led to intense light emission, prolonged light emission and low background[36]. Spontaneous light emission during reaction requires the presence of the following conditions[37]: The reaction must be highly exothermic (40-70 kcal/mole) in order that the CL-reaction occurred in the visible region (400 nm (violet) – 750nm (red). These exothermic conditions associated with redox reactions using Oxygen, Ozone andhydrogen peroxide or similar potential oxidants. The reaction pathway must be a favorable to channel the energy for the formation of an electronically excited state. Photon emission must be favorable deactivation process of the excited product in relation to other competitive non-radiative processes that may appear in low proportion. There are several ways for an electronically excited state species to lose its extra energy, either by reacting with another molecule, molecular dissociation, and collision with its surrounding molecules or luminescence. In the latter case it can react to liberate sufficient energy to produce photon of visible light, figure (1-3). Figure (1-3):-possible de-excitation pathways of excited molecule 1.2.2. Main Chemiluminescence-systems for analytical processes 1.2.2.1. Gas- phase chemiluminescence reactions. The development of Chemiluminescence Methods for determining components of a gas is largely originated from the need to determine atmospheric pollutants such as Ozone, Oxides of nitrogen and sulfur compounds[45, 46].The best known and most frequently used is the reaction of nitrogen oxide withOzone.CL-NOXanalyzers have been shown to respond to a number of nitrogenous pollutants besides NO and NO2. [40].Some analytical methods based on CL- reactions have been proposed for the determination of sulfur monoxide and unsaturated hydrocarbons such as Alkenes, alkynes and aromatics at high temperature,several of these are as follows[41-44]. NO+ O3NO2* + O2NO2 + hÃŽ ½(600-2800 nm)(1) (2) (3) Oxygen atoms also been applied as strong oxidants when reacted with a wide range of analyst, although not so frequently used. The reaction with nitric oxide produces a yellow- green CL-emission that has been used for measuring concentration of Oxygen atoms in kinetics experiments[45]. (4) Some CL. Reactions are based on the light emission produced in flame, rather than the cold CL-emission. Molecular emission cavity analysis (MECA) is a CL-technique in which molecular emission are generated within a cavity that is introduced into a hydrogen diffusion flame. This flame acts as the environments of radicals, atoms and molecules which promote the chemical reactions (i.e. high temperature of flame promote of chemical reactions that form key reaction intermediates and provide additional thermal excitation of the emitting species).The cavity acts as the environment for stabilizing the emitting species. MECA has been used for selective detection of compounds containing sulfur, nitrogen, phosphorous, antimony, arsenic,.Tin and halogens [46-54]. 1.2.2.2. Liquid- phase chemiluminescence reactions There are some well – established CL-reagents that have been used for solution – phase CL-reactions, their attraction include high sensitivity, wide dynamic range and simplicity [55].The Chemiluminescence of luminal and the cyclic hydrazides of aromatic and heterocyclic acids is one of the classical and still studied in CL-reactions [56]. Although hydrazides in general are Chemiluminescent, onlyhydrazides related to luminol (5 – aminophthalyhydrazide) can be considered the most commonly used. The CL. of luminol was first described by Albrecht in 1928. This compound reacts with potent oxidizing agents in the presence of catalyst in alkaline medium to yield 3 – amino phthalate in an excited electronic state which returned to the ground state; with the production ofblue emission at 425 nm.The reaction is catalyzed by metal ions.Alternatively, it has been proposed that the metal ion forms a complex with the hydrazide which is then oxidized[57–59]. Lophin(2,4,5 – triphenylimidazole) is the most representative of the imidazole CL-precursors . A yellow CL-emission is produced at 525 nm. by oxidation of Luphin in aqueous alkaline mediums[60]. Lucigenine(10, 10 dimethyl – 9, 9 -biascridiniumnitrate) is one of the most efficient CL-substances which emit an intense green emission at 470 nm. When oxidized in an alkaline medium [61]. In relation to indirect CL., one of the more efficient non – biological system that are used is based on and so – called peroxy oxalate CL-reaction (PO – CL ) which involves the hydrogen peroxide oxidation of an aryl oxalate ester in the presence of a fluorophore .Bis–( 2,4,6 – trichloro phenyl )oxalate (TCPO) and bis – ( 2,4– dinitro phenyl ) oxalate (DNPO ) are commonly used oxalates. These compounds are insoluble in water which requires the use of organic solvents such as acetonitrilies ,dioxane and ethyl acetate [62]. Another CL-system frequently applied involves the use of Ru [bpy]3+2 which produces an orange emission at 610 nm.From the excited state (Ru [bpy]3+2)* that can be obtained by different reactions which imply electron transfer and regeneration of Ru[bpy ]3+2 species. Recently , the higher CL-emission generated by a similar complex , Ru[phen]3+2(phen = 1,10 – phenanthroline) during oxidation ofRu [bpy ]3+2 by Ce(IV) in sulfuric acid medium Ru [bpy]3+2 is the most studied as an inorganic compound used in electro generated CL (ECL)[60,63]. 1.2.2.3.Solid Phase Chemiluminescence [35]. Some polymers exhibit weak CL. in the visible range when heated up in the presence of inert gas (air or oxygen). For the first time this phenomenon was observed by Ashby in 1961, from polypropylene. Emission of light during oxidation of polymers is called oxy- luminescence or oxychemiluminescence. And for CL. of polymers to be observed, oxygen must be present in the process. 1.2.3.Electro Generated Chemiluminescence (ECL) ECL : is the process in accordance with which , species generated at electrodes undergo high – energy electron – transfer reactions to form excited states that emit light , it occurs in the visible region of spectrum as a consequence of fast and highly exo-energetic electron . Transfer between a strong electron donor and electronacceptor which in turn results in generation of excited states [7].In general, electrically generated reactants diffuse from one or more electrodes, and undergo high – energy electron transfer reactions either with one other or with chemicals in solution. This process yields excited state molecules, which produce a CL- emission in the vicinity of the electrode surface. Application of ECL have almost exclusively focused on the reaction of tris(2, 2 – bipyridire) ruthenium Ru[bpy]3+2 the reaction takes place at room temperature . Wide pH range and in the presence of oxygen and many other impurities[64].Ru [bpy]3+2 itself can undergo electron transfer reactions to produce ECL as follows [65]. Luminol can undergo an ECL reaction due to its versatility in analytical determinations. in alkaline solution luminol anion undergoes a single electron electro-oxidation to form diazaquinine , which is further oxidized by peroxide or super oxide to give 3 – amino phthalate in an excited state , which emits light at 425 nm . Luminol ECL has been used for determination of species such as phenyl alanine, ibuprofen and hisidine [9]. 1.3. Fluorescence Photoluminescence becomes visible as optical radiation accompanied by the emission of photon depending on the duration of the phenomenon, i.e. life time of the excited state. Fluorescence is the spontaneous emission of light during transition of the system from its lowest vibrational energy level of an excited singlet state S1 back to the ground state S0,thus it’s a spin allowed process. Absorption and fluorescence don’t require any spin reorientation however; intersystem crossing and phosphorescence require a spin reorientation therefore; absorbance and fluorescence are much faster than phosphorescence. The processes that occur between the absorption and emission of light are usually illustrated by Jobalonski diagram [66, 67]; figure (1-4). Figure (1-4):- Perrin- Jobalonski diagram and illustration of the relative positions of absorption (Abs), fluorescence (F), andphosphorescence (Ph.) Fluorescence is the result of three stages process that occurs in certain molecules called fluorophores [67]. Excitation: a photon is supplied by an external source and absorbed by the fluorophore creating an excited electronic singlet state S1. This stage distinguishes fluorescence from chemiluminescence, in which the excited state is populated by a chemical reaction. State life time:fluorescence life time is typically 1-10 Nano sec. during this time the fluorophore undergoes conformational changes and is also subjected to a multitude of possible interactions with its molecular environment such as collisional quenching and intersystem crossing. Fluorescence emission: when a photon of energy is emitted returning the fluorophore to the ground stat S0. Figure (1-5) shows these three stages. Figure (1-5):- three stages of fluorescence emission process 1.3.1. Characteristics of fluorescence emission [68-70] Emission spectra are typically independent of the excitation wave length due to the partial dissipation of excitation energy during the excited state life time, this known as Kasha’s rule. The emission intensity is proportional to the amplitude of the fluorescence excitation spectrum at the excitation wavelength; figure (1-6). Figure (1-6):- emission spectra are typically independent of the excitation wavelength Stokes shift: due to the energy dissipation during the excited state life time, the energy of this photon is lower and therefore; of longer wavelength than the excitation photon (i.e.fluorescence light is a red-shift). This difference in energy or wavelength is known as stokes shift.† The difference in wavelength between positions of the band maxima of the absorption and emission spectra of the same electronic transition; figure (1-7). Solvent effects and excited state reactions can also affect the magnitude of stokes shift.

When absorption and/or the emission spectra of a flourophore possess two or more bands, stokes shift is equal to the difference that separates the two most intense bands of the two spectra, figure (1-8). Figure (1-8):-stokes shift in a flourophore possess two bands If thermal energy is added to an excited state or compound has many highly populated vibrational energy levels, emission at shorter wavelengths than those of absorption occurs, this is called an anti-stokes shift and its often observed in dilute gasses at high temperatures. A key feature of fluorescence is the molecule spends a measurable Amount of time in the singlet state. Fluorescence life time refers to the average time that the molecule stays in its excited state before emitting a photon for fluorescence; it’s typically in the range (1-10 nsec.). Fluorescence radiant power (F) is proportional to the absorbed radiant power. F = É ¸ (P0 – P) - (6) É ¸: Fluorescence efficiency. P0: incident power. P: transmitted power. The relationship between the absorbed radiant power and concentration can be obtained from beers law P/P0 = 10-A- (7) P = P0 Ãâ€" 10-Ɇºbc - (8)F = É ¸ P0 (1–10-Ɇºbc)- (9) Structural factors. Fluorescence is expected in molecules that are aromatic or multiple conjugated double bonds with a high degree of resonance stability, it’s also expected with poly cyclic aromatic
