Choose one gender group and critically discuss how their health outcomes can be improved in regards to ageing. Introduction Wound infection post-surgery, now preferably known as Surgical Site Infection (SSI) refers to infections at or near a surgical site within 30 days after surgery or within one year, if the procedure involved insertion of an implant (Illingworth et al., 2013; Owens and Stoessel 2008). While definite statistics of the incidence of SSI are complicated given the gamut of surgical procedures, environment and patients, available data indicate that SSI contributes to more than 15% of reported Hospital-acquired infections (HAI) for all patients and about 38% for surgical patients (Campbell et al., 2013; Owens and Stoessel, 2008; Reichman and Greenberg, 2009). Also, data from across Europe indicate that, depending on surgical procedure and/or surveillance methods used, incidence of SSI may be as high as 20% for all surgical procedures (Leaper et al., 2004). Don’t waste time! Our writers will create an original "How Gender Group Health Can Be Improved In Regards To Ageing" essay for you Create order Although, HAIs generally, and SSI are relatively less common in Orthopaedic surgery, compared with other surgical procedures (Johnson et al., 2013), however, when they do occur, osteo-articular infections for example, can be very difficult to treat, with significant risk of lifelong recurrence (Faruqui and Choubey, 2014). SSI leads to significantly higher costs of care from longer hospital stays; it poses a major burden on healthcare providers and the healthcare system, jeopardises the health outcomes of patients and remains a major cause of morbidity and mortality despite improvements in surgical procedures and infection control techniques (Owens and Stoessel, 2008; Tao et al., 2015). Consequently, understanding evidenced-based approaches to reduce/prevent incidence of SSI has attracted significant interests from researchers, healthcare administrators and policy-makers. This essay intends to review current best-practices in prevention of SSIs and to offer recommendations for future practice within orthopaedic settings. Rationale This review of best practices in the prevention of SSI following orthopaedic surgery is underpinned by two major reasons. One, despite the considerable improvement in surgical procedures and techniques in most orthopaedic settings, SSI negatively impact on patient outcomes and imposes significant cost on the healthcare system. According to a case-control study reported by Owens and Stoessel (2008), patients who suffer SSI are more likely to require readmission to hospital and have more than double the risk of death compared to patients without SSI. In addition, the median duration of hospitalisation required due to SSI was put at 11 days and the extra cost to the healthcare system estimated at à ¢Ã¢â‚¬Å¡Ã‚ ¬325 per day (Owens and Stoessel, 2008). Two, the prevention of SSI is hardly straightforward. Given the wide range of factors that modify the risk of SSI, a bundle approach with systematic attention to multiple risk factor is required for any effective prevention of SSI (UÃÆ'à ‚ §kay et al., 2013). Thus, by undertaking a state-of-the-art review of orthopaedic SSI prevention techniques/processes, this essay may contribute towards better orthopaedic surgery outcomes for patients and providers. Prevention of SSI in orthopaedic surgery: Best Practices According to the Health Protection Agency (2011), the most common pathogenic organisms responsible for surgical wound infections in orthopaedic surgery include methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant Staphylococcus aureus (MRSA), Coagulate negative Staphylococci (CoNS), Enterobacteriaceae, Enterococcus spp, Pseudomonas spp, Stretococcus spp as well as occasional cases of unspecified diphtheroids of the Corynebacterium spp. and other gram-positive organisms. Moreover, SSIs can be categorised into superficial incisional, deep incisional and organ space SSI (Reichman and Greenberg, 2009). Superficial incisional SSI refers to infection that involves only skin and subcutaneous tissue at the point of incision; deep incisional SSI refers to infection of the underlying soft tissues, while organ space SSI refers to infection involving organs or organ spaces that were opened or manipulated during the surgical procedure. Since the risk of ending up with SSI a nd the specific type of SSI suffered are determined by factors related to the patient, procedure and hospital environment, current best-practices and guidelines for preventing SSI can be broadly elaborated under these categories. Patient-related Practices Existing patient conditions like diabetes mellitus, obesity and/or rheumatoid arthritis have been associated with increased risk of SSI (Illingworth et al., 2013; Johnson et al., 2013). As part of effective patient management, pre-operatively, current body of evidence recommends aggressive glucose control for diabetes patient to reduce the heightened risk of infection due to hyperglycaemia pre or post-surgery. In patients with rheumatoid arthritis, corticosteroids and anti-tumour necrosis factor (TNF) therapy have been argued to delay wound healing and increase risk of infection. However, the British Society for Rheumatology (BSR) recommends that in deciding whether to cease these medications for such patients, pre-surgery, the potential benefits of preventing post-surgery infection should be balanced with the risk of disease flare, pre-surgery (Dixon et al., 2006; Luqmani et al., 2006). In addition, orthopaedic surgery for patients who currently smoke or are obese (BMI above 30kg/ m2) should be delayed (until smoking cessation/loss of weight) to reduce the risk of SSI. For example, a randomised, controlled study reported that smoking cessation for just 4 weeks significantly reduced the odds of incisional SSI (Sorensen et al., 2003), while Namba et al. (2005) reported significantly higher odds of SSI in obese patients (35kg/m2) undergoing total hip and knee replacement surgery, compared with patients that were not obese. Screening patients for presence of MSSA and MRSA and subsequent decolonisation is one of the most recommended techniques for preventing SSI. Staphylococcus aureus colonisation is reportedly found in the nares of about 30% of healthy individuals (Kalmeijer et al., 2002). This nasal carriage of both methicillin sensitive/resistant S. aureus have been demonstrated as a significant risk factor for SSI. Kelly et al. (2012) reported a significant drop in SSI from 2.3% to 0.3% with the use of intranasal mupirocin and triclosan showers to decolonis e patients before orthopaedic surgery. Also, a review of eight randomised controlled trial by van Rijen et al. (2008) reported that the use of mupirocin significantly reduced the incidence of MRSA and MSSA associated SSI. However, guidelines from the National Institute for Health and Care Excellence (NICE, 2008) recommends a combination of nasal mupirocin and chlorhexidine showers for patient decolonisation while UÃÆ' §kay et al. (2013) indicated that available evidence from orthopaedic literature suggests that S. aureus screening, decolonisation and shower constitute a cost-saving, effective strategy to reduce the incidence of SSI in orthopaedic surgeries. Surgical Procedure-related Practices Preoperative preparation of skin before incision is one of the major avenues to prevent SSI (Kelly et al., 2012). However, there is no consensus on what antiseptic agent offers the most effective protection against SSI. While NICE (2008) guidelines suggest that both aqueous and alcohol based preparations e.g. povidone-iodine or chlorhexidine are suitable for skin preparation, Darouiche et al. (2010) and Milstone et al. (2008) have raised concerns about the development of bacterial resistance to chlorhexidine. These studies report the relative superiority of 2% chlorhexidine mixed with 70% isopropyl alcohol, while some experts have suggested increasing the chlorhexidine concentration to 4% or the use of 10% povidone-iodine (UÃÆ' §kay et al., 2013). Nevertheless, povidone-iodine or chlorhexidine still remain the gold standard for preoperative skin preparation. Also as part of skin preparation, NICE recommends that hair should only be removed if necessary, should be done immedia tely before surgery and with electronic clippers, not razor blades. Recent evidence suggests that use of razor blades can sometimes result in microscopic skin cuts that may act as foci for micro-organisms colonisation, thus increasing the risk of infection (Owens and Stoessel, 2008). Preoperative administration of antibiotic prophylaxis to reduce the risk of surgical wound infection is widely accepted for surgery in orthopaedic settings, including bone trauma. Several large scale studies have demonstrated that antibiotic prophylaxis, when administered properly, help reduce tissue contamination, during surgery, to levels that do not overwhelm the patients immune system, and thus, can reduce the risk of SSI by up to 75% (Chen et al., 2013; Faruqui and Choubey, 2014; Illingworth et al., 2013; UÃÆ' §kay et al. 2013). However, NICE (2008) recommends that potential adverse effects, optimal dosage and most effective time for administration pre-operatively should be carefully consider ed to maximize the benefit of antibiotic prophylaxis. UÃÆ' §kay et al. (2013) believe that first or second generation parenteral cephalosporins are sufficient in most cases, except in cases of skin colonisation with MRSA, in which case glycopeptide antibiotics may be more effective. However, this should be considered in relation to individual patients allergy history. UÃÆ' §kay et al. (2013) also recommend that 30mins à ¢Ã¢â€š ¬Ã¢â‚¬Å" 1hr before incision is the idea time to administer prophylaxis. While this is generally accepted, NICE (2008) recommends that prophylaxis may be given earlier in procedures where a tourniquet is used. In addition to minimising the risks from the skin and endogenous flora of the patient, the surgical team must also strive to reduce chances of contamination from either their person, the tools used or the procedure itself. NICE (2008) recommends that every member of the surgical team must thoroughly scrub before wearing surgical gown and gloves . There is growing support for double-gloving and frequent glove-changing to reduce the risk of contamination from tiny punctures in surgical gloves that often go unnoticed during surgery. While evidence in support of double-gloving and/or frequent glove-changing intra-operatively as a strategy for reducing risk of SSI remain inconclusive, Widmer et al. (2010) conclude that the practice is supported by expert opinion, especially for lengthy procedures. Moreover, excellent surgical techniques are crucial in preventing SSI. For example, maintaining effective haemostasis while preserving adequate blood supply, removal of devitalized tissues, eradication of dead space(s), gentle handling of tissue and effective management of surgical wound postoperatively can all help reduce the chance of SSI (UÃÆ' §kay et al., 2013). Hospital Environment-related Practices The CDC and World Health Organization recommend that doors to the operating room should be kept closed and traffic kept to a minimum to reduce potential contamination of surgical sites (Tao et al., 2015). To achieve this, essential equipment and tools should be stored in the operating room. In fact, Health Protection Agency (2011) suggest that frequency of operating room door opening is a positive predictor of increased bacterial count in the operating room. Airflow in the operating room is another modifier of SSI risk. Vertical or horizontal laminar-flow ventilation systems have been advocated for orthopaedic surgery to achieve ultra-clean air within the operating room and reduce airborne contaminants. Although evidence supporting the effect of laminar airflow systems on SSI risk remains inconclusive, the reduction in airborne contaminants is perhaps an added advantage (Owens and Stoessel, 2008; Reichman and Greenberg, 2009). Lastly, constant surveillance is an important part o f preventing SSI. By following up on patients post-operatively and reporting appropriate data to the surgical team, surgical decisions can be improved upon based on historical records (SkrÃÆ' ¥mm et al., 2012). Moreover, surveillance ensures that cases of SSI are identified early and treated before complications arise. Data from surveillance could also form the basis of evidenced-based decision making on facility specific service improvements to reduce incidences of SSI and improve outcomes for all concerned (SkrÃÆ' ¥mm et al., 2012). Recommendations This essay have reviewed current knowledge on surgical site infection and strategies to reduce its incidence. It is pertinent to state that despite the various precautions elaborated above, complete eradication of surgical site contamination is almost impossible as some endogenous micro-organisms always remain and environmental factors cannot be totally eliminated. To reduce incidence of SSI to the barest minimum, the following are recommended: It is crucial to adopt a bundle approach that ensures that patient, procedure and facility related factors are controlled for as much as possible. While improving surgical and care delivery is always crucial, surveillance and data collection should also promoted to ensure that changes/improvements in procedures and facility practices are evidenced-based New technologies and strategies are continually been developed to reduce complications like SSI and improve outcomes for patients, it is important to always stay on top of these developments to ensure that orthopaedic surgeries are not only evidenced-based but contemporary, achieving the best outcome possible for all parties. Conclusion Surgical site infection (SSI) poses a significant challenge to patients undergoing orthopaedic surgeries, the surgical team as well as the healthcare system in general. SSI negatively impact patient outcomes and imposes unnecessary demand on healthcare resources. Fortunately, much of the burden associated with SSI can be avoided. This review identifies the multitude of patient and procedure-related factors that modify SSI risk and highlights various evidence-based strategies to mitigate these risks. The paper demonstrates that there is consensus in the literature that by screening and subsequent decolonisation of patients, administering antibiotic prophylaxis, ensuring that surgical tools, equipments and garments are properly sterilised and the operating room is free of airborne contaminants, cases of surgical wound infection in orthopaedic surgeries can be effectively prevented.

Mental Illness, Schizophrenia, And Eating Disorders

Like physical illnesses, mental illness is on a scale of severity. Although more than roughly 60 million Americans have some form of a mental illness a small amount actually seek or are given treatment. The statistic most often quoted is that one in four adults and one in five children will have a mental health disorder at some point in their lives. (What is Mental Illness? n.d.). The overall stigma that comes along with a mental disorder is still one of the biggest barriers that prevents those from obtaining treatment or retaining their treatment. â€Å"While there are over 200 classified forms of mental illness, the five (5) major categories of mental illness are: Anxiety Disorders, Mood Disorders, Schizophrenia/Psychotic Disorders, Dementias, and Eating Disorders.† (What is Mental Illness? n.d.) We all of come across anxiety in various forms throughout the routine of our day to day activities. However, the mechanisms that regulate anxiety may break down in a wide variety of circumstances, leading to excessive or inappropriate expressions of anxiety. An anxiety disorder may exist if the anxiety experienced is disproportionate to the circumstance, is difficult for the individual to control, or interferes with normal functioning. More than 19 million American adults are affected by an anxiety disorder. Children and adolescents also develop anxiety disorders.

A Firearms Violence on Teens Free Essays

Despite nationwide gun-free school laws that prohibit possession of a firearm on or near the property of a public or private school, students are bringing guns to school and using them against their fellow students and teachers with increasing frequency. What possesses these students to gun down their classmates? How are these students getting access to firearms? Who is ultimately responsible for these tragedies? What stresses contribute to these shootings? And how are parents and educators missing the warning signs that these children have reached the breaking point? Over the past few years, there have been an astronomical number of school shootings across the country, sending policy makers, parents, teachers, and other concerned citizens into a tailspin. These events are becoming more frequent and have shattered the sense of safety that children should have when they are in school. We will write a custom essay sample on A Firearms Violence on Teens or any similar topic only for you Order Now Shootings by students, some as young as 10, have occurred at sickeningly regular intervals in urban towns like Pearl, Mississippi, Jonesboro, Arkansas, Fayetteville, Tennessee and most recently Littleton, Colorado, where 12 students and 1 teacher lost their lives at the hand of two teen shooters who took their own lives. Firearm violence falls second only to automobile-related deaths, as the leading cause of injury-related death, in the United States. By the year 2003, firearm fatalities are projected to become the United States leading cause of injury-related death, unless the violence is curbed. In 1991, Texas and Louisiana saw firearm fatalities surpass automobile fatalities, and Virginia and Nevada also have continued this trend. In fact, the firearm death rate is increasing faster than any other cause of death except AIDS related fatalities. Recent public attention has focused on the problem of gun violence in the nation†s schools. A 1994 Gallup poll of Americans, for the first time, fighting, violence, and gangs have moved to the top of the list to tie with lack of discipline as the biggest problem facing schools. It is difficult to determine what effect the threat of violence has upon the learning of each student, but clearly education takes a back seat to one†s own sense of security and well being. According to a survey conducted by the Centers for Disease Control, one in 20 high school students carry a gun and one in five students would tell a teacher if he or she knew of another student carrying weapons to school. Theories differ about where young people get their guns. School security experts and law enforcement officials estimate that 80% of the firearms students bring to school come from home, while students estimate that 40% of their peers who bring guns to school buy them on the street. The United States has weaker firearm regulations and higher numbers of deaths involving firearms than all other industrialized nations. The greatest tragedy of gun violence is the tremendous numbers of children and youth killed or injured each year by firearms. These numbers continue to increase at alarming rates. According to Gunfree.Org, in 1985, the number of firearm homicides for youth 19 years and younger was 1,339, in 1995, it was 2, 574. In 1995, guns accounted for 84% of homicides of persons 13 to 19 years of age. Averages of 14 youth each day are killed by gunshots. A group studying juvenile violence in Multhomah County, Oregon identified the inadequate response of the juvenile justice system to students expelled for possessing weapons in schools, the need for additional efforts to detect weapons, and anti-violence education in schools as primary concerns. We must, as a society, recognize that there is a cycle of violence and that violence breeds more violence. There is no single answer to the problem of violence. A multi-faceted approach is needed. Prevention must be a priority. According to a ‘Public Health† Approach, recognition of three levels of prevention activities is essential: Primary prevention: These are interventions directed at people who have no obvious risk factors for development of violence. An example would be teaching grade school children to deal constructively with anger and conflict. Secondary prevention: These activities are directed to those who show clear-cut risk factors for violence. An example would be training in anger management for people who have a history of arguments or fighting. Tertiary prevention: These activities are directed toward minimizing the danger caused by those who have displayed violent behavior. Examples include interventions to allow gang-established patterns of serious or repeated violence. Any approach to violence must include education carried out in various ways and settings including collaboration among community groups, businesses, the schools, and government. Most of all, the parents must get involved. Schools offer the opportunity to reach a substantial percentage of the youth population and teach them skills aimed at the reduction of violence. Teachers are able to identify early on problem youth and families. Schools represent an important site to convey the message of society against weapons and violence. An important part of the anti-violence prevention strategy aimed at all youth is increasing the efforts to detect weapons in schools. While schools are already vigilant about responding to individuals when specific knowledge is available about weapons possession, this approach has not addressed concerns and perceptions that a number of weapons are present in schools undetected. Expanding the commitment to zero tolerance for weapons in schools would also better communicate to youth community standards, assuming that adequate consequences are in place. Most weapons are found through reporting by a concerned student. Such reporting should be praised. The National School Safety Center offers a checklist derived from tracking school-associated deaths in the United States from July 1992 to the present. Through studying common characteristics of youth who have caused such deaths, the following behaviors are a sampling of indicators of a youth†s potential for harming him/herself or others: History of tantrums and uncontrollable angry outbursts. Habitually makes violent threats when angry. Has previously brought a weapon to school.

Is Downloading Free Music from the Internet Unethical Essay Example For Students

Is Downloading Free Music from the Internet Unethical? Essay Is Downloading Free Music from the Internet Unethical? Copyright infringement is not a new issue. The issue has been debated in court since the development of the VS.. In Sony Corp.. V. Universal City Studios, the court ruled that the sale of copying equipment was legal because the VS. was capable of substantial infringing uses. (Hairbrush) The issue with music sharing is that its only purpose is a copyright infringing act. New advancements in technology have always made life faster, easier and more convenient. Theyve also had their share of court cases, which have defined rules and set guidelines for future cases. When trying to determine if downloading music from an online source is ethical, one must look at various court cases throughout the years to understand the history of the issue. The following court cases could help one make such a decision. A Records vs.. Anapest (2001) Their activities were ruled to be inductive to financial gain from illegal infringement. (Laws. Com) MGM Studios, Inc. . Grosser, Ltd. (2005) Providers of Software thats designed to enable file sharing of copyrighted works may be held liable for the infringement that takes place using that software. (Copyright. Gob) Arises Records LLC v. Lime Group LLC (2006) By distributing and maintaining Limier (they) intentionally induced direct infringement by users. (Gavin) Victim Vs.. Google (2007) Youth was not liable for infringement because it removed unauthorized videos when informed about them. Jeffrey) The consensus of previous court hearings seems to be that free music downloads are unethical because the artists are not being paid for their work. This however, has not deterred other websites from offering free music downloads. Tensions have eased substantially, as Youth has set up an automated system to detect and block infringing videos and has signed revenue-sharing agreements with more than a thousand media companies. I believe that original websites like Anapest, who didnt pay royalties to copyright owners, were unethical.

Nursing Experience free essay sample

When I was a kid back then I was dreaming of going to America. My parents advises me to study hard and pick a profession that is in demand every part of the world. I was so not prepared on what profession that is in demand so my sister Belinda who was studying Nursing at The University of Santo Tomas encouraged me to follow her footstep. I was contemplating to take Medicine but my brother Manolo who was an Intern at the Jose Reyes Memorial Hospital in Manila was complaining of sleepless night and unable to attend family reunion especially on Christmas and New Yeara eve. He would drop by just to have a quick bite of foods. So this type of work interupted my ambition of becoming a doctor. So I was back again to Nursing. On my era at that time Nursing profession were more on the ladies side except if you are gay. We will write a custom essay sample on Nursing Experience or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page So took a big gamble and decided that profession. I love to take care of people and be voice of the patients especially if they do not receive the proper care that they deserve. I graduated in 1979. Took the board exam and almost landed among the top 10 where highest grade on my exam was 85% and my score was 81. 3 %. Too bad I did not made it but satisfied enough that I passed it with flying colors compared to my Summa Cum Laude who got 75%. Right then I went directly to practice Emergency Room nursing which I love it very much due to I could practice all the fields that I studied. Being in the E. R. it requires intelligence, able to identify the problem of your patient thru the sign and symptom they are manifesting, laboratory result, chest x-ray report, CT scan report and other test that were done. Anticipation on what will happen next and what is your solution before that problem comes in. Being in the field of nursing even getting you license is not enough to make you to be good on what you had studied as basic knowledge. You had to constantly take advance learning skill like continuing education in regards to your specialty or other specialty to stimulate your thirst for extra knowledge. In my fields I have taken basic ECG reading and interpretation , advance ECG interpretation , Advance Cardiac Life Support , Basic Cardiac Life Support , CPR, Bone Marrow Interpretation , Understanding pain and their different methods of treatment modalities. Advance Nursing care of old people, Advance nursing care of neonates ; pediatrics ,cancer patients ,etc.. So Education does not end after you graduated from college. It is a continuing process of your professionalism. Besides here in the US it is mandatory to take a 30 hrs. of continuing education that is related to your profession before you could renew your license which is every 2 years. There is no exemption to the rules of the California Board of Nursing. Now I have 2 kinds of Nursing specialty which is Dialysis. In dialysis I have to study Plasmapheresis, Continuous Veno-Venous dialysis ( CVVH), Continuous Ambulatory Peritoneal Dialysis and lastly Hemodialysis. To be on that field you have to go to school for this specialty. It is not just you go for training that what in the Philippines does. Her it is different. You have to be certified by that specialty. You have to pass the difficult test. You have to meet the requirement that is you should be a BSN graduate, had 2 years of Acute hospital training or work, 1 year of hemodialysis work experience. The certification does not increase your salary but but your Status Quo. It makes you proud of yourself of what you had accomplish to upgrade your profession. People pay respect on you when they see that letters after the word R. N. Now I do specialized again in two settings of Hemodialysis which is Acute Dialysis which is the hospital setting. In that setting you perform the dialysis treatment either Peritoneal dialysis or Hemodialysis in the patients room. You had to follow where that patient is located either in Emergency Room ,Surgical Intensive Care Unit, Intensive Cardiac Unit, Coronary Unit, Pulmonary Unit, Pediatric unit,Orthopedic, Rehabilitation unit, Psychiatric Unit, Medical or Surgical Unit , except for Operating Room and Obstetric where you do not want to contaminate that area with germs. On the clinic side I am a Clinical Nurse Manager. I have to manage the clinical side and Business aspect of the clinic. I have to take care of the entire population of hemodialysis which is 125 patients in 2 days that is excluding the Peritoneal dialysis patients. I have several position besides being the Clinical Manager, I am also the Infectious Disease Manager and Anemia Manager. You see you have a lot of responsibility when you are in a position and working on a big company. Taking a big responsibility is not easy but rewarding once you had accomplished what you are aiming for. My advise to you is be a leader, excel in what you do, be a pioneer in your field and be a voice of your PATIENTS. Check your facebook account. I answered what I could think of in that small box I am typing. You could pick my picture with my Marilyn Monroe.

Criminal justice Reform essays

Criminal justice Reform essays People are arrested every day in the United States. They are put on probation or sent to jail, and sometimes they are let out on parole; there are millions of people affected. In 1995 alone there were over five million people under some form of correctional supervision, and the number is steadily increasing. The incarceration rate is skyrocketing: the number of prison inmates per 100,000 people has risen from 139 in 1980 to 411 in 1995. This is an immense financial burden on the country. Federal expenditure for correctional institutions alone increased 248% from 1982 to 1992. Obviously something has to be changed in the justice system. If the crime rate is rising this much, the correctional justice system isn't functioning properly, and needs to be reformed. Many people have offered theories as to what should be done with the prison system, the extremes being retributivism and the therapeutic model, but what they all seem to have overlooked is that there is no single system that work s for everyone. Blanket generalizations as to the nature of the criminal mind cannot be made. Every criminal is different, with different motivations and different psychological characteristics so that different things are required to make them repent or deter them from further criminal activity, and I believe that the solutions offered are not enough to lower the crime rate and prison population. Something needs to be done on a more fundamental level so that fewer people turn to crime in the first place, thereby providing the prison system with the freedom to improve the attention it gives to the people that do become criminals; my solution is a combination of economic reform and educational opportunity that would give people less reason to commit crimes. The extreme right reform proposition, retributivism, is flawed mainly because it seems to assume that showing people that what they've done is wrong will always accomplish something, and that every priso...

US Democracy Essay Example | Topics and Well Written Essays - 1250 words

US Democracy - Essay Example The question how democratic is democracy in U.S may seem challenging to a lay man but it is clear from the U.S constitution that the states practice democracy in almost all their dealings. However to some extent America system of governance has failed to adopt some of the some of the innovations and modifications in the democratic systems and ideal. The United States constitution allows the common citizens to participate in various democratic processes such as election and taking part in referendum in case there is any. However to some extent the American democracy gets dilute day by day with more of her power Washington. The states are becoming more republic consolidated government. The "politically correct" and "historical revisionists" have soiled United States with restrained but disparaging autocracies that have extremely dented our free democratic people. Politicians use the term democracy when they need something from the publics, and they use the term republic when they do no t need something from the citizens. It is political system and where the legal force is regulated through given and enumerated powers. For instance, the United States Constitution, and predominantly the Bill of Rights, was premeditated to limit governments part to what United States’ founding forefathers saw as governments utmost vital functions. The main functions were to reserve individual liberty and defend private property. Moreover, Persons differ in their perception of a limited government, nonetheless, one common understanding is that a limited government is one that imposes just ample taxes to deliver for state defense and police security and then stays out of publics undertakings. As an example, a limited government is one that does not distress itself with issues such as what sallies should employees get from the jobs they do, retirement investment schemes of

Our company is considering entering the manufacturing market for snow Research Paper

Our company is considering entering the manufacturing market for snow skis. You have been asked to examine all material(s) that - Research Paper Example A number of companies mainly in United States and Europe are currently producing Snow skis. Throughout the history, various materials have been used in making of skis and advancement continues to be seen. Skis manufacturing have a long history. Based on archeological studies, a wooden ski was first identified in at Lake Sindor in Russia, the skiing equipment was dated to have been in use between 6300 and 5000 BC.(Burov 393). This is the earliest evidence involving the use of skis. Apart from artifacts of skis, many historical drawings and paintings have shown skiing activities where individuals use the skis. Ski construction started becoming dominant in the end of nineteenth century especially in Austria and Switzerland (Classic skis 1). The architecture of these early alpine skis was simple but they were wide and short. These characteristics enabled the skis to have high agility, hence capable of the ability to penetrate areas with deep snow and elevated areas. Since these early tim es, the designs, shape and the materials used in making skis has continued to diversify. Different types of wood have been used in the construction of the skis, varying from wood, plastics, metals or a blend of the three. The main materials in making of skis have been wood for the better part of the twentieth century. Different wooden materials have been in use depending on the place where the skis are located. Today some companies have retained the use of wood but the technology seems not attract many of the skiers. The initial wooden skis were curved using hands, to make simple skis (Wooden skis 1). In the modern setup, this design has completely changed with the adoption of a torsion box architecture that is more sophisticated and requires additional materials to make. Because of the water-properties of wood, other materials have taken its place. This has created limited use of wood in the modern context. Skis are simple skiing equipment but they are made up several parts. It is important that a ski buyer is familiar with it in order to get the best ski for the desired skiing. The base is the part of a ski that has direct contact with or faces the ground surface. Most of the skis’ bases in the modern times are made of aluminum or fiberglass. The camber is space that is evident at below the centre of the ski. Contact points are the positions of attachment between the ski and the snow without the rider imparting pressure on it. The waist is the part of the ski that is narrowest, usually appearing at the centre of the side cut. Other parts of the ski include the top or otherwise called the deck where the bindings are placed. It also has the effective edge, the tip, the shovel, and the side cut (ABC of Skiing 1). Various categories of the modern day skis are manufactured depending on the material used. The classic wooden skis are curved using hands; they are long and have thin sides, an aberration from the original design. In addition, they have a rectan gular shape but have a curve in one of the ends. Another form of skis was advanced to use steel, these are the so-called edges, and their architecture varies because of the screwed steel at its bottom. Wood and metal laminates have also been developed, the wooden laminate involves pieces of wood that are glued together, and these are flexible, stiff and are lighter. Metal laminates were initially made of aluminum but proved inefficient; they had to blend aluminum with wood. Advancing with the technology the

The Importance of Management and Marketing within Business Essay

The Importance of Management and Marketing within Business Organization and the Impact of Technology - Essay Example This research will begin with the statement that it is difficult to define management in few words because of the complex parameters involved in the management process. In simple terms, management is the process of dealing or controlling things or people. One of the most common function of management is getting things done through others. â€Å"According to Henri Fayol, "To manage is to forecast and to plan, to organise, to command, to coordinate and to control† whereas Peter Drucker, defined Management as a multi-purpose organ that manages business and manages managers and manages workers and work". From the above definitions, it is evident that management is highly complex term which has got multi-dimensions. On the other hand, marketing is a process of informing the customers about the value or utility of a product or service, and to encourage the customers to purchase it. â€Å"It is defined as the process of determining the needs and wants of consumers and being able to deliver products that satisfy those needs and wants. Marketing includes all of the activities necessary to move a product from the producer to the consumer†. Management is a process which helps to achieve; group goals, Optimum Utilization of Resources, reduction of costs. It is a process which establishes sound organization and equilibrium. Moreover, it helps the society to achieve prosperity. Man, material, machine, and money are the four most important resources of an organization. Management is the process, which helps the coordination of all these organizational resources. For example, finance department is responsible for the management of money in an organization. Same way, human resource department look after the manpower resources whereas engineering or production department look after the machineries and materials. Even though different departments are controlling the organizational resources, it is the process of management, which helps them to utilize these resource s judiciously so that the organization benefits from these resources. Many people have the illusion that management is a function restricted only to the executives of an organization. In fact, Management is a function usually undertaken by people of all calibre. For example, a housekeeper is responsible for managing the resources of a house properly whereas a construction worker is responsible for managing the works assigned to him. A housewife manages the education of her children while her husband manages other family matters. In short, management is a function which can be seen everywhere. It is impossible for this world to move a step forward without management of different kinds. All organizations depend upon group efforts. Group action and joint efforts have become necessary in every walk of life. Management is required wherever two or more people work together to achieve com ­mon objectives. The success in group efforts depends upon mutual cooperation among the members of t he group. Management creates teamwork and coordination among specialized efforts. Management is indispensable in all organizations whether a business firm, a govern ­ment, a hospital, a college, a club, etc. Management is a creative force which helps in the optimum utilization of resources. No two individuals are alike. This is true in the organizational world also. It should be noted that current organizations are heavily globalized so that they forced to employ people from different parts of the world. Diversity helps organizations in many ways. At the same time diversity creates lot of problems also. Coordination of diverse workforce is extremely difficult. Management is the process, which helps human resource managers to coordinate diverse workforce effectively.

Partial Rate of Diffusion of Potassium Dichromate

Partial Rate of Diffusion of Potassium Dichromate ABSTRACT Diffusion is the process where molecules spread into spaces. It was observed that the formation of ammonium chloride was near the hydrochloric acid meaning the ammonia diffused faster. One factor that affects the rate of it is the molecular weight of a substance. If molecular weight affects the rate of diffusion, then, the higher or lower the molecular weight the slower or faster the rate of diffusion. To test this factor, a drop of potassium dichromate, potassium permanganate, and methylene blue were placed on each wells of the petri dish containing agar water gel. After thirty minutes, the partial rate and average rate of diffusion are calculated and the results showed that the substance with the lowest molecular weight, potassium permanganate, diffuses fastest. The molecular weight affects the rate of diffusion, the lighter the molecular weight the slower the rate of diffusion and vice versa. The molecular weight of the substance is inversely proportional to the rate of diffusion. INTRODUCTION Diffusion is the process where the molecules of solid, liquid or gas spread spontaneously to occupy a space. Gas molecules are the fastest to diffuse since their molecules are scattered from one another. The molecules of diffusion moves randomly and they spread into available space (Mendoza E, 2003). Hydrochloric acid is formed by mixture of hydrogen ion and chlorine ion. According to the Lewis’ theory of acids and bases, hydrochloric acid is an acid because an element (chlorine) was paired to a hydrogen ion and when it is dissolved in water, it produces hydrogen ion (Ebbing and Gammon, 2011). A 0.1M of hydrochloric acid has a pH level of 1 meaning it is strong enough to dissolved iron nails (Mendoza E, 2003). Hydrochloric acid has a molecular weight of about 36.46 g/mol and can be found inside our stomach because it helps on the digestion of the food we eat (Reece et al, 2005). Ammonium hydroxide is a base because it produces hydroxide ion when dissolves in water. The ammonium hydroxide decomposes forming ammonia and water. In a decomposition reaction, a compound turns into simpler substances or elements. The ammonia has a molecular weight of about 17.031 g/mol and water has about 18g/mol (Mendoza E, 2003). When ammonium hydroxide breaks down into ammonia and water, since hydrochloric acid is an acid, when it is dissolved in water, it will produce hydrogen ion. On the other hand, the chlorine ion(C ) will react with ammonia (N). This reaction is called synthesis reaction (HCl + N O → NCl + +O) (Mendoza E, 2003). From the reaction, ammonium chloride is produced by the synthesis of ammonia and chlorine ion. The ammonia and hydrochloric acid spread to available space until they meet. After they met, a reaction of white powder is formed. The ring is near to the hydrochloric acid compare to the ammonia (France C. 2014) There are many factors that affect the rate of diffusion. When heat is applied, the molecules moves quicker, making the solute dissolves faster. The diffusion rate also increased by stirring where molecules move faster between the molecules of water. Diffusion is also affected by the density of the solvent where diffusion is slower when it has a higher density (Lozano Sandico, 2003). Molecular weight also affects the rate of diffusion. Lighter particles diffuse faster than heavy particles It has an inverse proportionality where the smaller the size of the particles, the faster the rate of diffusion (Tro, 2008). The difference in concentration can affect the rate of diffusion too. The distance of diffusion also affects the rate of it where it takes time to diffuse a particle for farther place. Permeability is also a factor of diffusion where if the substance does not permit a substance to pass through it, thus, there will be no diffusion (Meyertholen E., 2014) Based on the observation, the ammonium hydroxide decomposed into ammonia (N) and water (O), while the hydrochloric acid decomposed into hydrogen ion() and chlorine ion (C). A single displacement had occurred from the ammonia and hydrochloric acid, forming ammonium chloride (NCl). This substance appeared in the tube in the presence of a white smoke. With this, data were obtained to know how molecular weight affects the diffusion of a certain substance. As seen in table 4.1, comparing the ratio of the distances from the two substances up to the smoke over the total distance, the ratio of the ammonia are bigger than the ratio of the hydrochloric acid. But on the first trial, the ratio of hydrochloric acid over total distance is bigger by 0.2cm compared to the ammonia. Using the formula, the ratio of the ammonia over the ratio of hydrochloric acid is used to get the average ratio. With ammonia having a molecular weight of about 17.031 g/mol and the hydrochloric acid having a molecular we ight of about 36.46 g/mol, the lighter the molecular weight of the substance, the faster the diffusion is. However, the molecules of the substances on the observation cannot be seen. Table 4.1.

The specific objectives are: To explain the relationship between molecular weight and the rate of diffusion of a certain substance. To prove if molecular weight affects the rate of diffusion, then, the higher or lower the molecular weight the slower or faster the rate of diffusion. MATERIALS AND METHODS To find out if the molecular weight of a substance affects the rate of diffusion, a petri dish of agar water gel with three wells, potassium dichromate (C), potassium permanganate (KMn), and methylene blue were used. The diameter of each well is measured in millimetre using a ruler. Then, a drop of potassium dichromate, potassium permanganate, and methylene blue were dropped on each wells of the petri dish containing agar water gel. It was immediately covered to prevent it from drying. At a three-minute interval for thirty minutes, by lifting the petri dish, the diameter of the coloured area is measured. Using the collected data in the setup, a line graph was used to compare the rate of each substance’s diffusion. RESULTS AND DISCUSSION On the experiment, potassium dichromate, potassium permanganate, and methylene blue in agar-water gel inside the petri dish were used to determine the partial rate and the average rate of diffusion. After 30 minutes of observing, the diameter of the potassium permanganate has the biggest among the rest which is 14, compared to the potassium dichromate which is 12 and to methylene blue which is 11. The average rate of diffusion is calculated by the formula: Where: df= final diameter do= initial diameter t= total time While the partial diffusion rate is calculated by the formula Where: dx=diameter at a given time dx-1= diameter immediately before dx tx= time when dx measured tx-1= time immediately before tx Table 4.2.

SUMMARY AND CONCLUSION To test the hypothesis, an experiment was performed to test if the molecular weight affects the rate of diffusion, then, the higher or lower the molecular weight the slower or faster the rate of diffusion. An observation using a glass rod to measure the distance on how far the particles of the hydrochloric acid and ammonia travelled until both of them had a chemical reaction producing ammonium chloride. Ammonia that has 17.031 g/mol travelled faster than the hydrochloric acid that has 36.46 g/mol. The experiment was done to support the observation because it is more clearly and visible to the naked eye because the diffusion can be observe in this setup. The potassium permanganate having a diameter of 14 is the biggest among them. The average rate of diffusion of each substances was calculated and the result is potassium permanganate has the fastest rate of 0.367mm/min. potassium permanganate has the lightest molecular weight of 158g/mol. Based from the setup that was performed, the substance that has the lightest molecular weight has the fastest rate of diffusion. This study confirmed the hypothesis where the molecular weight affects the rate of diffusion, the lighter the molecular weight the slower the rate of diffusion and vice versa. The molecular weight of the substance is inversely proportional to the rate of diffusion. However, some errors were made during the experiment like the unequal amounts of the substances placed in the petri dish, methylene blue was spilled from the well, and the three substances are not measured at exactly every three minutes. This study needs further research because there are also other factors other than the molecular weight that could affect the rate of diffusion. It is recommended to research and study other factors that can affect the rate of diffusion.

Education without Truth in Postmodern Perspectivism :: Argumentative Linguistic Papers

Education without Truth in Postmodern Perspectivism Poststructuralist relativism, following the Nietzschean critique of Western rationalism, denounces the quest for truth as a quest to legitimize various claims on the level of universal human value, by covering up the indirect coercion of their discourse or imagery. Using perspectivism as an argument against philosophical grounding of various patterns and schemes, post-modern thinkers, under the influence of Poststructuralist relativism, try to depart from the cognitivist tradition by transforming philosophical thought to an edifying discipline (Rorty) or learning (Lyotard) liberated from a theory of knowledge, and giving into a discourse of literary or prosy character. I argue that post-modern perspectivism and the individualistic or collectivistic logic which nurtures its scope can be transcended through construction of hyperperspectivistic prisms based on alogic of interrelation animated by the interdisciplinarian spirit prevailing in the field of modern science. This latter serves as the leading thread for the foundation of a new canonicity which, without losing its historical and cultural character, can make claims to truth and validity of general acceptance. The hyperspectivistic canonicity deriving from such an interrelational logic is in a position to animate a new educational model capable of overcoming both idealistic and romantic versions of Bildung. During the last third of 20th century, the so-called postmodern world has been technically modernized in an unprecedented way. An unconstrained capitalist economy imposing constantly changing technologies determine, among other systems of social control, various forms of the educational system, each one of them promoting knowledge as a commodity. The ferment that swept, some years ago, not only the Third World but also the industrial societies for revolutionnary change of social and political institutions has given its place to a forceful modernization of established authority, political power and modes of accummulation. The belief that we live in a rapidly changing world is well spread. In fact, we live in a frenetically modernized but not changing world, given that the deification of the modern against the traditional forms of education, organization and communication levels the need to create a vision of a future society. The creation of such a vision presupposes the critical approach of the legitimacy of the established authority, of political power or wealth; issues which are no longer broadly discussed. The early and forceful advocates of libertarian or socialist values seem to be forgotten or definitely marginalised. (1) The philosophical tradition developed by philosophers like

Business Model: Amazon versus eBay Essay

A company’s business model is the activities it uses to create and capture value through its offerings to the market. Modelling helps firms develop business visions and strategies, redesign and align business operations, share knowledge about the business and its vision and ensure the acceptance of business decisions through committing stakeholders to the decisions made (Persson & Stirna , 2001). Amazon and eBay both share space in the retail industry of e-retail and e-commerce services. The two companies have found success by conducting business using the internet by providing products, services, and information to consumers. Although, B2C (business to customer) strategies have helped both companies to achieve success they have sustained and dominated the market through evolving business models that capitalize on value creation to the consumer. eBay’s business model is based on creating an online trading community where the company provides an auctioning platform that brings sellers and buyers together. Thousands of items are listed in catalog form according to topic and category. eBay at no time takes possession of any item which leaves shipping costs details between the buyer and seller. However, it does offer secure payment methods free of charge. On the other hand, Amazon incorporates a long tail retail business model which assumes that products that are in low demand or have low sales volume can collectively make up a market share that rivals or exceeds the relatively few current bestsellers and blockbusters, but only if the store or distribution channel is large enough (Investopedia, 2014). By offering a large variety of products on its sites for sell inventory is kept in what the company terms as fulfilment centers. Whereas when merchandise is selected and paid for through Amazon’s e-commerce site it is shipped free or at little cost to the buyer. The value creation does not end once the exchanges of goods have taken place for both eBay and Amazon they have extended the transaction process by incorporating feedback forums. For example eBay depends on the integrity of others in making person to person ethical transactions; there is a feedback forum where the seller and buyer can comment on the process. Amazon in turn has created customer value and loyalty by offering a comment section where buyers can rate experience on a star system, and provide reviews. The seller is tracked by Amazon using a  metric system based on number of reviews and ratings in percentages telling how much positive feedback a seller has received in a specific time. heavily and leverages its fixed assets to and On the other hand, Amazon beginning as an online book seller utilizing B2C strategy quickly redefined its retail strategy to include large varieties of products that are stored in what it The company in compensation charges listing fees or insertion fee to promote the product, and a final sales price fee of 7.9% once the final bid is accepted. Through these activities eBay creates value to the consumer by providing a vast listing of items for sale in one location, ease of use, and security in financial payment methods. Although, eBay’s business model is built around its core competencies of on-line person to person auctioning Amazon has taken a more innovative approach by redefining its business model and creating entirely new markets. Amazon begi nning as an online book seller utilizing B2C strategy quickly redefined its retail strategy to include large varieties of products.

Hence Amazon dumps short term profits for long term investments often making the company appear not profitable in its financial statements. Amazon through business model innovation (BMI) evolves by thinking long term continues to fill the white space by focusing and then capitalizing on the unmet needs of consumers. The company since inception in 1995 Amazon started off by focusing on Business-to-Consumer relationships between itself and its customers, and Business-to-Business relationships between itself and its suppliers but it then moved to incorporate Customer-to-Business transactions as it realized the value of customer reviews as part of the product descriptions. t is when an online company earns its revenues mainly by selling a broad selection of products.

Biography Essay Example | Topics and Well Written Essays - 500 words

Biography - Essay Example Incredibly powerful and talented women have either isolated themselves in lonely closets or succumbed to drug addiction, and even committed suicide because they feared both societal and familial rejection. From a historical perspective, the pressure women faced in the past is understood. However, even today, women in the upper echelons of society still have to choose between silence and success. However, Perko decided to speak out about the rights of people due to the fact that she witnessed others being mistreated. Some people are settled in the United States; however some do not receive the same education and treatment as white students due to the fact that they are viewed as a minority race. Furthermore, because of their lack culture acknowledgement from teachers, sometimes American students require educational intervention, which is actually lacking knowledge in their culture even though they have settled in the United States for hundreds of years. From there, this is why she recorded some people were very proud when they had a chance of education.

Analysis report of Bernini's Angel with Crown of Thorns Research Paper

Analysis report of Bernini's Angel with Crown of Thorns - Research Paper Example Through its huge size and magnificent form, it became a grand architectural element together with the rest of the ten Angels of Passion in Ponte Sant’Angelo. A grand sentry looking over the people as they traverse the bridge to and from the Castle. The sculpture depicts an angel represented as a young man with a crown of curly hair. His wings are quite huge and are partially spread out as if about to take flight. He is wearing a somewhat diaphanous material draped over his body exposing a good portion of his shoulders and his right leg. He is holding a crown of thorns and his arms are placed sideways towards the left side of his body at the level of his chest. The angel’s right leg is exposed up to mid thigh and is bent on the knee as if in a walking motion. His left foot, on the hand, is also exposed. His feet are parted slightly apart with an indistinguishable object of swirls in between his feet and beside his left feet. The Ponte Sant’Angelo, also known as the Bridge of Angels, in Rome was decorated with ten marble sculptures of angels, or the Angels of Passion, as proposed by Italian sculptor Gian Lorenzo Bernini.1 He was commissioned by Pope Clement IX to create two out of the ten angel sculptures and the rest of the angel sculptures are believed to be made by Bernini’s students. The ten marble sculptures are to replace the 14 stucco sculptures of angels set up by Rafaella da Montelupo under Pope Paul III.2 The ten marble sculptures of angels each hold a symbol of the Passion of the Christ. The ten angel sculptures are the â€Å"Angel with the Column† by Antonio Raggi, â€Å"Angel with the Whips† by Lazzaro Morelli, â€Å"Angel with the Crown of Thorns†Ã‚  by Gian Lorenzo Bernini, â€Å"Angel with the Sudarium or Veronica’s Veil† by  Cosimo Fancelli,  Ã¢â‚¬Å"Angel with the Garment and Dice† by Paolo Naldini, â€Å"Angel with

Greek mythology is a valuable collection of narratives of Greek God, Goddesses, heroes, and heroines (Kerenyi, 1951). In the Greek mythology, Selene or Lunar was an ancient lunar deity, and was sometimes described as Artemis. Titans Hyperion and Theia are the parents of Selene. Helios, the sun is the brother of Selene. Eos, the Goddess of dawn is the sister of Selene. The journey of Selene begins when the earth turns dark at night. The story tells that Eos carried off a human lover Cephalus (Burkert, 1985). The story also narrates that Selene loved a shepherd, or otherwise named Endymion. The man was so handsome that Selene asked Zeus to make him immortal so that they won't ever depart. Endymion made a decision to live forever in sleep. Thus, Selene and Endymion had fifty daughters. The story adds that Selene and Zeus had a daughter called Pandia (full moon). Hecate, originally a Goddess of the wilderness and childbirth is today seen as a Goddess of witchcraft. She had her connotations as a Goddess of sorcery and played the role of Queen of Ghosts. The title, Queen of Ghosts with Hecate has its in-depth association with the then prevalent belief that she can prevent the occurrence of harm

Nathan Songs of Silence Essay Example for Free

Nathan Songs of Silence Essay The chapters of Songs of Silence hold together as a chorus of songs from one community, but shaped by the recollections of a narrator whose perspective ranges from the innocence of childhood to the maturity of a young adult who emerges unbroken from a failed relationship. One such chapters is ‘Nathan’ and here the narrator is the reflective adult with a sophisticated notion of the wide range if meanings ‘silence’ holds. Through the character of Nation she is able to present some aspects of this theme, which runs throughout the text in many different ways. Nathan acts strategically without words, but with potent meaning – revenge (poking Tony’s eye). Silence is a characteristic feature of Nathan’s personality, which is deep and profound even though he uses few words. The absence of words can mask/hide a great deal (still waters run deep). Nathan’s deep and profound silence was evident even from his birth and the close connection he had with his sister, the narrator – ‘†¦soulmates, welded together by our common need for silence.’ They both started speaking late. However, her silence was different from his – ‘he was a man of dark blue silences,’ while hers ‘hers was a silence of moons.’ Here the narrator suggests that contrary to the saying ‘silence means consent’, silence does not always mean ‘consent’ or agreement nor are all silent people to be treated the same. The ‘manna manna manna mahkita’ game establishes the communication between the narrator and Nathan. It has unspoken personal meaning for them and suggests that its ritual is saturated with almost religious or spiritual significance. It shows that codes of communication which may appear insignificant or meaningless to others looking on, may be a way of expressing connections that (known) words cannot express. The different silences of the siblings allow them to explore, define and find their own authentic selves in their own ways. (E.g. The narrator and the ants, Nathan and his tightfistedness with money). Silence, like money, can express identity.

Consumers Behaviour Shaped By The Media Advertising Media Essay

Consumers Behaviour Shaped By The Media Advertising Media Essay The mass media in todays society has shape the way we act, think and react to certain outcomes in our lives. It has such an impact on the choices we make and the choices that are available for us to make, that we sometimes dont even know its there. This often creates an awareness of the roles and attitudes we are expected to react to through commercialism. Advertising is the art of convincing people to spend money they dont have for something they dont need (Rogers, 2004 ) and these desires of wanting these certain products are largely the results made by the mass media. Perhaps, marketers should look at a different way of targeting consumers without having to mould their minds in such a way that has changed our uniqueness as an individual living in todays global world. Consumer behaviour is often described as the way we make decisions in purchasing specific products. Factors such as economic, demographic, psychological and social influences have played a major role in influencing our behaviour as consumers (Quester McCarthy, 2001). However, as we go into depth, the long term consequences of commercialism are much more serious than we imagine. So are we to blame the firms and organisations for manipulating our minds as consumers? Or are we too fragile to resist such temptation. According to the American Marketing Association (AMA), consumer behaviour is defined as the dynamic interaction of affect and cognition, behaviour, and environmental events by which human beings conduct the exchange aspects of their lives (American Marketing Association 2006). While another definition has defined consumer behaviour as The study of individuals, groups, or organizations and the processes they use to select, secure, use, and dispose of products, services, experiences, or ideas to satisfy needs and the impacts that these processes have on the consumer and society (Hawkins, Best, Convey Koch, 2004). So we ask, is this definition still effective in this scenario, especially when our attitudes and perceptions are being tampered with? Some people feel that they are not affected by advertising, but they are. The media not only advertises directly, but they also try to appeal to people on an unconscious level Its harder to persuade them when theyre thinking (The Ad and the Ego, 1997) shows just how manipulative the media can be. For example, in 2001 the tobacco industry tried persuading its customers by using terms such as light to mislead smokers into believing that those brands are safer. They also made it seem like smoking is a part of everyday life. In many ads that promote tobacco, smoking is introduced as a natural part of having a good time. This as a result encourages consumer into supporting tobacco companies by purchasing their light cigarettes. Advertising is the means by which goods or services are promoted to the public (Petley, 2003). The advertisers goal is to increase sales of these goods or services by drawing peoples attention to them and showing them in a favourable light (Petley, 2003). According to (Arens in Ayanwale, Alimi and Ayanbimipe, 2005), the mission of advertiser is to reach prospective customers and influence their awareness, attitudes and buying behaviour. They spend a lot of money to keep individuals interested in their products. To succeed, they need to understand what makes potential customers behave the way they do. Advertising is a marketing function, and Kotler (in Bokor, Werner and Richardsson; 2004) claims that advertising can have a number of different, possible objectives. One objective can be to inform customers about new product or a price change, while another objective can be to persuade. In this sense advertising is a phenomenon that aims to persuade or influence people (Bjurstrà ¶m, 199 4). Most of the critics today believe that the use of commercialism has dramatically changed the way consumers behave and the way they carry out their lifestyle. Looking at the examples present in todays society, its possible to say that these theories may be pretty accurate. For example, Advertisers often emphasize sexuality and the importance of physical attractiveness in an attempt to sell products. They often emphasise thinness as a standard for female beauty, and the bodies idealized in the media are frequently atypical of normal, healthy women. You are continually competing with everyone around you to be noticed, to be seen, to be admired, to be successful. Ads urge us to become what we behold. It is advertising which defines physical beauty for women. Modern advertising conditions women to strive for an unattainable standard of beauty all in the service of selling products. Women frequently compare their bodies to those they see around them, and researchers have found that exposur e to idealized body images lowers womens satisfaction with their own attractiveness (Magazine Models Impact Girls Desire to Lose Weight, Press Release, 2008). As a result, the depiction of thin models has adversely impacted womens body image, which has led to unhealthy behaviour as women and girls strive for the ultra-thin body idealized by the media. Advertising images have also set unrealistic ideals for males, and men and boys are beginning to risk their health to achieve the well-built media standard. Advertising that pushes people to be small and eat large supports eating disorder thinking and behaviour. The continual onslaught of emaciation, body surgery, and diet publicity actually convinces many people that the lifestyle being portrayed is normal. Such media portrayal validates starvation, cutting behaviors and binge and purge cycles. Plus, this portrayal can delay recovery work. If a person with an eating disorder is subjected to a barrage of images and messages celebrating the symptoms of her illness, she may believe she is living well and wisely and will not seek treatment. This is a cultural phenomenon that is tragic. It contributes to people taking pride in their illness, proselytizing eating disorders, destroying their health, ruining relationships and, in far too many cases, shortening their lives. So do advertisers see such an impact theyve done to consumers? The main objective of advertising is to convince the consumer to behave in a certain manner which is most favourable for the advertiser. It may influence the consumer in different ways, because the advertiser spends an enormous amount of money to sell his product in the most creative and persuasive manner possible. Before 1900 advertising was mostly informational. Ads described products and appealed to consumers logic and judgement. World War I and the 1920s saw advertising shift from text to more emotional and image-centered modes. Advertising became less about products and more about the emotional and social lives of the people buying the products. The growing industrial economy dictated that not only goods but also markets for goods needed to be mass-produced. Soon, advertisements began to promote anxiety, discomfort, and inadequacy among the population. Youre not OK the way you are, You need help. You need salvation Ads generate anxiety and doubts making us feel uncomfortable in our skins. This we call the production of discontent (Hawkins, Best, Convey Koch, 2004). Advertising sells more than products, it sells values, images, concepts, and above all, normalcy it tells us who we are and who we should be. Advertising teaches us above all to be consumers. It teaches us that happiness can be bought, that there are instant solutions to lifes complex problems, and that products can fulfil us and meets our deepest human needs. We live in a consumer culture, saturated with mass media images. Much of our physical, informational, and cultural space is for sale billboards, TV, magazines, newspapers, even the area behind home plate. All of these spaces pitch products promising to improve our lives. We are all, sometimes consciously, sometimes unconsciously, affected by this advertising, often in very subtle ways. Whats important is not our experience of any one ad but that of living in an advertising environment which repeats certain messages again and again. We dont see it very well because we re-surrounded by it all the time. Like Richard Pollay (in Pollay, W; 1979) explains that just as a fish dont think about the sea, we dont think much about ads because we are surrounded by this ad environment from birth to death. He argues that one of educations goals ought to be to get the fish to think about the water. In order to understand modern society, he concludes, advertising is the best place to look. Humans are meaning-making creatures, always wondering who i am? and why do things work the way they do? After a century of experience, advertisers understand the power of symbolism and strive to discover symbols that make people react in predictable ways. Advertisers try to create stimuli to make individuals salivate if you can grab people their emotions, you can get them to follow. We have a cultural disposition to believe what we see. The human brain processes images and words differently. What we reflect on, consider, and even argue with logical appeals built on words, but we dont talk back to images. Advertisers realize that people are more easily influences by images than words. Seeing advertisements on the television, billboards or hearing them on our favourite radio stations has become a part of our daily lives whether we like it or not. Being exposed to numerous advertisements do affect our behaviour in some way what so ever. As a consumer myself, I strongly believe that advertising has a detrimental effect to peoples behaviour in many ways. We tend to follow our primary instincts and forget the real values in life. By acting on our insecurity and self-consciousness advertising makes us more inclined to products we are once happy with. We covet and envy our friends. We become greedy and are never satisfy with what we have. Advertising has created consumerism which affects our ability to communicate with each other. Most people nowadays prefer sharing their thoughts through electronic mail or latest cell phones than personal contacts. We have definitely become more distant from one another and consumerism is probably the main cause of this social alienatio n. On the other hand, while advertising have a negative impact on our personality it may also have a positive impact on economy. The fewer commercials we see, the less amount of money we spend. For a large company and its competitors, advertising has become the only way of introducing products to the customers and for us sometimes it is the only way to learn about what they sell. One of the main indicators of a healthy and strong economy is the money flow or how much money is spent, in other words how much money advertising has succeeded to get out of our pockets. This results in low unemployment rate and increase in our standards of living. Despite the fact that advertising will be thriving on our weaknesses in the years to come, we should try not to become slaves to material things and do our best to retain core values which after all distinguish us as human beings.
