Perfume by Patrick S
Perfume by Patrick S A Story of a Murderer - a Story of FranceIn this very essay I am going to reflect on the vivid description of historical and cutlural contents in the novel "Perfume" - the recognised masterpiece of the modern literature written by Patrick SÃÆ'Ã ¼skind in 1984.Before focusing on the novel itself, let us look back into France, the place of the novel's events, into the XVIII century, and outline its atmosphere. At that time this country, together with the most of Europe, was coming through the Age of Enlightenment - a period of intellectual movement that proclaimed rationality and reason as a new means of thinking and building social life. A big step forward was done by science, which got rid of the mystical element and let medicine, chemistry, physics, economics and other branches of knowledge develop.Significant changes in economics were taking place as well. The form of production was turning from shops into capitalistic industrial enterprises; overseas trade arose.The picture show s a gathering of distinguished gue...The leading role in economics started to belong to merchant manufacturers who posessed raw materials. There were also national enterprises - royal manufactures.In cultural respect, the synonym of the French Enlightenment is stronly associated with the name of Voltaire - dramatist, publicist, historian and philosopher. Such vivid personalities of that time like philosopher and writer D. Didreau, thinkers J.J. Rousseau and Montesquieu, satirist BomarchÃÆ'Ã ©, D'Alembert, Robespierre and others should also be menioned.Owing in many respects to all them, the power of mind embraces the society and criticism of church obscurantism arouses. It becomes important to exchange philosophical, scientific and aesthetic ideas between countries. The French language turns into international language of educated people. Together with this, the social class of intelligence is being formed.And now let us get familiar with the details of this...

Managerial Accounting Practices - Essay Example Another disadvantage of fixed costs is that they eliminate flexibility and make the job of managerial accountants much harder. Variable costs change depending on the level of sales. Also a managerial accountant can find ways to eliminate or reduce variable costs easier than fixed costs. A costs structure in which variable costs are more influential than fixed costs is more likely to have a lower breakeven point. The breakeven point is the amount of sales necessary to cover all expenses. There are many fixed costs in which Claire Corporation is incurring. Some of the companyââ¬â¢s fixed costs include building rent, salaries of administration staff, and depreciation of equipment expenses. The companyââ¬â¢s plan of expanding the amount of distribution centers is a move that will definitely increase the companyââ¬â¢s fixed costs. The overall sales have to increase to justify that strategic choice. If variable costs are reduce it would increase the contribution margin of the company and raise its profitability. The situation of having to liquate merchandise due to excess inventory must be remedied immediately. If the company adjust its cost structure geared towards variable costs instead of fixed costs the plan of creating a just in inventory system would bring greater benefits for the company. There are ways for the company to begin the transformation process to moving away form unnecessary fixed costs. A fixed I had not mentions that is major problem in the company is maintenance costs of the equipment. Some of these machines are obsolete and should be replaced immediately. Buying new machine would eliminate most of the wastage and unnecessary maintenance costs. I also evaluated the company debt situation. The firm has multiple long term loans that were incurred when the firmââ¬â¢s credit score was low due to company being a newcomer in the industry. Now our business credit rating has gone up a lot.

Organisation Promotion Plan - Essay Example Firstly, with regards to where and how the product should be advertised, it is this analysts understanding that trade journals and relevant publications would be an effective mechanism for attracting the attention of potential clients (McGann et al., 2013). Whereas it might be understood that advertising in the likes of The Economist could be effective, the truth of the matter is that this is far too expensive and would require a very large amount of money to engage effectively; therefore making other smaller and more specific publications within the specific trades that might be targeted much more effective. The sales strategy itself will be highly concentric upon delineating an effective message to the consumer. As might be expected, the message that will be immediately trade is with regards to the ultimate loss of utility and profitability that can be realized as a result of conflicts among stakeholders. With regards to the means through which this will be represented, graphical r epresentations will need to be created that promote both an understanding of the emotional aspects of conflict as well as the direct correlation between this negative externality and the overall profit margin that a company might enjoy (Shrestha, 2012). In such a way, the ultimate message that the sales strategy will seek to engage will be somewhat synonymous with the advertising strategy. By seeking to evoke an emotional in this will response within the part of the stakeholder towards the need to mitigate and reduce conflict management, the end consumer will be fully cognizant of the fact that immediate action needed to be taken and the product/service integrated with in order to reduce the ultimate threat that this poses (Goldsmith & Amir, 2010). Similarly, with regards to the time frames and ultimate risk that this particular strategy entails, it must be understood that no particular promotion plan can realize success in a rapid period of time. Rather, a level of patience and exp ectation of the amount of time that it can take before this particular approach begins to return a profit must be engaged upon all stakeholders within the firm in question (Ailawadi et al., 2006). One of the necessary risks that exist with respect to the means by which the product to be integrated is of course the overall activity that the economy may take between now and the time in which the product is fully represented the consumer. Naturally, if the economy begins to worsen, services such as conflict management solutions, will necessarily not be as attractive or deemed as useful to a mere form of survival. Finally, with respect to why the consumer should buy this particular service as compared to the litany of others that are on the market, a sustained level of discussion should be provided with regards to the promotional and advertising material with respect to the ultimate level of experience and expertise that this particu

Existing Philosophies in Education Essay Example for Free
Existing Philosophies in Education Essay Introduction ââ¬â Sex and the education of the children and youth about it is a point of social concern that always creates ethical, moral and professional criticisms, because of reasons ranging from the consideration of the topic of sex and its position in contemporary beliefs as well as the constant tug-of-war between conservative and liberals in education as to what should be done best in sex and its place in the educational system. The article Talking about Sex provided an insightful point in this particular dilemma that modern day societies face today, noting the persistence of ââ¬Ësex and sexualityââ¬â¢ in modern day advertising while people at the same time frown on the idea of teaching sex education inside schools and learning institutions. A Family Education. com article puts the issue in a better perspective, saying that teachers as individuals also carry their own particular ââ¬Ëissues and concernsââ¬â¢ about sex and that it may affect the manner by which the teacher teaches about sex education. Kakuchi (2004) reports about how Japan considers general sex education as something that is considered harmful to some children even when the same report acknowledges the fact that the focus on a more streamlined sex education is very urgent in the country with the knowledge of the educators and academicians of the level of awareness of children about sex and how a large portion of it was not taken from school lessons, classroom discussions and home teaching, simply because the requirements of the effective sex education teaching will go against existing traditional practices and societal beliefs which would not bend and accommodate this particular educational need children continue to face even now that the world is in the 21st century. Many believe that sex should be taught in school, while others believe that it should remain in the confines of private education, in a manner of how-a-person discovers it, so that it retains the sense of privacy that sex should have. For institutions that teaches sex education, there still is a snag every once in a while especially if the manner by which sex education is being taught does not create the proper mindset, attitude and learning experience for the student. As much it is highly necessary that children are provided with the correct information about sex education, most of the time, the process is not as simple as that. What is equally important is thatâ⬠¦ Some may argue that sex education is something which should be taught by a specific person, but the truth is every teacher is responsible for having sufficient knowledge in sex education because it is something that everyone experiences; it is something that everyone would be wondering and curious about, ââ¬Å"all kids wonder about where babies come fromâ⬠, says an article about teaching sex education; it is not math that general and complex computations should be memorized and mastered for the teacher to become a competent instructor in this particular topic, since sex is less of a topic and more of an everyday experience and teachers should help the students synthesize the everyday experience with sex curiosity and the information that it provides / generates by the demonstration of the effective use of the inquiry method in teaching. Research statement One of the reasons for the poor synthesis of children of the solicited facts, beliefs and possible fallacies involved in the overall education and formulation of the set of beliefs as well as the foundation for the attitude and behavior towards sex and the human reproductive system is the absence of the key characteristics expected of teachers as explained in the inquiry method or inquiry education espoused by Neil Postman and Charles Weingartner, and that as a result of which, many present day sexual deviants and sex-related criminals are, in part, a section of the group (that which contains individuals with adverse sexual inhibitions and bearers of misguided sex-related information) that fail to be good learners because of the ineffective use of the inquiry method / inquiry education by the teacher, particularly about sex. Supporting Arguments ââ¬âThe research statement will be dissected through the more specific discussions of particular key points that make up the series of supporting arguments that the paper will provide the linchpin for the main point of the research statement, which is significant today now that many educators and academicians are in constant search for the perfect formula in teaching sex education, particularly in countries wherein there are no noticeable effect of sex education and that problems previously attributed to the lack of sex education is still prevalent despite the presence of sex education today. In Japan, these problems are very visible in statistics concerning teen age sex, teen age pregnancy and other sex-related social concern, this despite the fact that Japan is teaching sex education to school children as early as the third grade. First, teachers become failures in the effective use of the characterisitcs for good teachers in the inquiry method every time they provide direct and exact answers to sex-related inquiries by children because of the belief that this is what traditional morals dictate. Postman and Weingartner (1969), in the book ââ¬ËTeaching as a Subversive Activityââ¬â¢, noted that in the process of the utilizing the characterisitcs of the inquiry method effectively and using it to effectively teach and address student concerns, teachers should avoid providing direct answers, more so, avoid enforcing sex-related information in a what-you-ought-to-know format. The common pitfalls wherein teachers fall into is the yielding to the instinct of providing answers to questions in a as-a-matte-of-fact way, which is not incorrect but is also not the only way to teach sex education. Teachers should know that there is as much emotional and psychological aspects in the teaching and learning of sex education as there is the physical aspect of teaching sex education that students should be allowed the avenue to feel that individual feelings and the differences in personal life background also matter in the discussion and in the overall learning process involved in sex edu cation. But the problem is that there are many cases that this is not followed, and this is generally because of the fact that sex education in some areas in the US and predominantly in other traditional and religious countries are still taboo ââ¬â classroom teachers and academicians continue to avoid the fact that the exposure of todayââ¬â¢s children to more and more forms of mass media and popular media coming from different culture other than theirs are all factors in the increased development of a childââ¬â¢s inquiry towards sex and other topics that may pertain to physical intimacy, the sense of sexual pleasure and sex. Teachers should anticipate the fact that while the inquiry of the children about sex are most probably homogenous and focused on the same area, the teacher should still avoid providing exact, boxed in answers and instead allow students to ventilate their queries and throw questions at each other so that the sense of ââ¬Ëtabooââ¬â¢ in the topic is diminished, allowing for the collapsing of the walls that it built inside the cognition of the child and allowing the entry of teacher-mediated ideas that do not stop, as sex education is a process of continuous learning. Secondly, some teachers misinterpret the idea that Postman and Weingartner proposed in their collaborative work about how teachers should use questioning and the use of divergent questions as a form of facilitating the influx of ideas between students by instead questioning the sense of right and wrong and personal morals of the students (which puts the morality wall up and closes the avenue for the entry of information and education) and by providing questions that divert the discussion / topic entirely to another different topic so that the teacher removes herself / himself from the position of being morally and ethically responsible for the sex education of the students, generally because of the acknowledgment of the teacherââ¬â¢s own incompetence in both the use of inquiry method as well as the absence of the mastery in the subject. What Postman and Weingartner had in mind when they explained this particular characteristic of the inquiry method is that the teacher should provide some questions himself/herself to students so that they can allow the students to explore more into the topic, thus allowing education and learning traffic to move consistently in and around the classroom and inside the minds of the students. Another proof to the high possibility of the presence of problems in teaching sex education with regards to the misuse and lack of adherence to the inquiry method is that sex education is usually in a uniform structure that hinders spontaneity and limits discussion in a specific area, resulting to some students suppressing questions or having questions which were left unanswered while the teachers themselves are not aware on how to facilitate the discussion once questions start pouring in and may seem to lead farther and farther from the original point of discussion. Again, it should be reiterated that since it is an experience which may carry different emotional and psychological baggage for every individual, teachers should not deliver lessons about sex like it is as simple as addition in a math class or the use of correct subject-verb agreement in an English writing and grammar class. The Family Education websiteââ¬â¢s article on teaching children sex education points out that adults who teach it cannot ââ¬Ëplan when and where children choose to ask difficult questionsââ¬â¢ about sex and as indicated in the inquiry method in teaching, teachers should allow the flow of questions and mediate through the discussion sufficiently. It does not end there, literally and figuratively, for teachers, since lessons, according to Postman and Weingartner should be allowed to develop on its own through the active participation of the student in the question-making and answer-searching. Family Education. com considers sex education, whether at home or in school, as ââ¬Ëan ongoing conversationââ¬â¢ and that if the blanket of openness and support that the inquiry method allows to develop take form in the course of the learning of the child, then teachers should expect more questions and continue with the task required in setting and defining the answers to questions as dictated by the inquiry method.

Ethics of the USA PATRIOT Act Essay -- Foreign Intelligence Essays
Ethics of the USA PATRIOT Act Another week, another series of patches to download from Microsoft. It seems like every week, Microsoft is under siege from one virus or another. The complexity in the billions of lines of code embedded in its products make it impossible to be error-free. If it is this easy for hot-headed M$ haters to breach the worldââ¬â¢s largest software maker, one has to ask: how hard would it be to expose vulnerabilities in the most sophisticated and technologically dependent country in the world? That is exactly what the US government is mulling about. The Information Age has brought unparallel speed of communication plus an immeasurable breadth of information to our fingertips. On the same token, it is also seeing the birth of newer and cleverer ways to create weapons that are too small to detect, too easy to produce, and too widespread to catch them all. For years, the government tried expanding its powers, first in the Reagan Administration, then the Bush (I) Administration, only to be rejected in the Legislature time after time. However, after the 1996 Oklahoma Bombing, the executive branch received some powers. But not until 9/11 did the government win unprecedented expansion of powers from the USA PATRIOT Act (Incidentally, Congress was going to pass a law to repeal those won in 1996 prior to 9/11).

Bacillus Cereus
B cereus has been discovered since 1955 as a cause of food poisoning (Luna etal 2007). 52 cases of food borne diseases connected with B cereus were reported in the interval between 1972 and 1986 and only two cases were reported in 2003 which represent about 2 % of the actual cases due to underreporting and many of the case go undiagnosed(Benenson 1990) . According to the south Carolina department of Health and Environmental control and CDC,close to 25% of state public health laboratory do not carry out B cereus testing routinely (Kramer& Gilbert 1989).The Centre for Disease Control estimates that 97% of all cases of food poisoning come from improper food handling; 79% of cases result from food prepared in commercial or institutional establishments and 21% of cases result from food prepared at home (Terranova & Blaker 1978). The most common etiologies are as follows: (1) leaving prepared food at temperatures that allow bacterial growth, (2) inadequate cooking or reheating, (3) cross-c ontamination, and (4) infection in food handlers (Blaker 1978).Cross-contamination may occur when raw contaminated food comes in contact with other foods, especially cooked foods, through direct contact or indirect contact on food preparation surfaces. Bacteria cause approximately 75% of the outbreaks of food poisoning and for 80% of the cases with a known cause in the United States (Blaker 1978). As many as 1 in 10 Americans has diarrhea due to food-borne infection each year. The 2 syndromes associated with B cereus food poisoning include short incubation or emetic syndrome with I.C=1-6 hours and the long incubation or Diarrhea syndrome with I. C=6-24 hours (Kramer 1989). Fried rice is the leading cause of emetic syndrome in the US (Bean 1990; Terronova 1978). Heat stable emetic toxin (ETE) is responsible for the short incubation period syndrome while the heat labile enterotoxin is responsible for the long incubation syndrome (Bean etal 1990) Syndrome Types of Bacillus Cereus food poisoning Bacillus cereus food poisoning has two varieties namely the emetic syndrome as well as the diarrhea syndrome types. B.cereus has some toxins responsible for its pathology and such toxins produces diseases that tally more with intoxication than absolute food poisoning. The emetic type can usually be confused with staphylococcal food poisoning due to its short incubation period (Luna etal 2007). However staph aureus being an important cause of food poisoning produces infection following growth in protein and carbohydrate foods. The enterotoxins of S aureus are super antigens and are heat stable making them resistant to the action of gut enzymes .As small as 25 microgram of enterotoxin B can produce diarrhea and nausea (Luna etal 2007). The emetic effect of this toxin is believed to be as a result of central nervous effect following the action of the toxins on the gut neural receptors (Ficker etal 2007). Some strains of staph aureus produce enterotoxins during their developme nt in meat, dairy foods and other food products and characteristically, this food usually has been recently prepared but has not been properly refrigerated. Almost 6 distinct types of staph enterotoxins exist.Following the swallowing of the preformed toxin, it is taken in by the gut mucosa and subsequently stimulates neural receptors and this stimulus is transferred to the vomiting centre in the brain and this projectile form of vomiting usually occur after few hours and it is less frequently associated with diarrhea and staph food poisoning is regarded as the commonest form. The food poisoning due to staphylococcus are usually associated with a smaller incubation period when compared with B cereus (from 1 to 8 hours).It is also associated with a very violent, copious nausea, diarrhea and vomiting all occurring in the absence of fever(Benenson 1990). It should be noted that with the emetic type where the incubation period is 2-8 hours, the prominent symptom is vomiting whereas in th e diarrhea type with incubation period of 8-16 hours the prominent symptom is diarhoea. Other species of bacillus are infrequently associated with human pathologies and difficulty arises in differentiating superficial contamination with B cereus from the authentic disease caused by this same organism .About 5 species of the Bacillus are aetiologic agents in insects and they include: B larvae, B lentimorbus,B sphericus,B papillae and B thurigiences and some of them have been taken advantage of by their use as insecticides(Fricker etal 2007) . Incorporation of the gene from B thuringiesis into some commercial plants has been recently achieved and this subsequently has generated a lot of controversies among the activists on environmental issues about the safety of these genetically fashioned food and plants products (Guerrant and Bobac 1991).Food types associated with food poisoning While the emetic type is associated with foods like fried rice and in fact the leading cause in the US ( Black low &Greeberg 1991), the diarrhea syndrome is associated with the likes of sauces and meat. The short incubation type is linked with fried rice that is cooked and kept warm for many hours and is also often associated with Chinese foods. A previous outbreak has revealed macaroni and also cheese from milk being the source of the bacterium.Incubation Period of the two syndromes of B. cereus that causes Food poisoning In the emetic type the diarrhea usually last for about 24 hours and it usually start 1-5 hours after the ingestion of the food substance like rice and it may also follow the ingestion of pasta foods. Food poisoning of the long incubation period i. e. 10 to 24 hours is the diarrhea type and this type may be confused with clostridia food poisoning. Mechanism of action ETE-forms small molecules, channels and holes in membranes.HBL-stimulates intestinal fluid secretion by various mechanisms including activation of adenylate cyclase and pore formation. Toxin of B-cereus i nclude emetic toxin (ETE), Nhe and EntK. Only 2 of the 3 enterotoxins participate in the causation of food poisoning and they consist of 3 different protein substitute acting together. HBL is a haemolysin while Nhe is not . EntK is a single component protein and not associated with food poisoning (Terranova&Blaker 1978). The 3 enterotoxins of B cereus have cytotoxic effect and they act on cell membranes forming holes and channels in them.People at risk of developing food poisoning The high risk population for food poisoning includes the older adults and this is due to the fact that as you get older, your immune system may not respond as quickly and as effectively to infectious organisms as when you were younger (Blacklow & Greeberg 1999). The Similar explanation goes for Infants and young children because of the immaturity of their gastrointestinal tract and also their immune systems havenââ¬â¢t been so fully developed.People with chronic diseases are also at risk of food poisoni ng because having a chronic condition, such as diabetes or AIDS, or receiving chemotherapy or radiation therapy for cancer reduces your immune response. Clinical features The clinical symptoms produced by the emetic type include abdominal pain, vomiting, nausea and self limiting type of diarrhea. The clinical symptoms of the diarrhea or long term incubation syndrome include fever and vomiting in rare cases but most prominent symptoms are profuse diarrhea and abdominal pain.The intestinal toxin is usually preformed but it can be produced inside the intestinal tract (Kramer &Gilbert 1989). To make a meaningful diagnosis of this organism, one will require that a load of about 105 of the organism is present in the feaces and just the presence of the organism not up to this maximum concentration is not enough to diagnose. Also importantly, B cereus is an important aetiologic agent of eye diseases such as panopthalmitis, endopthalmitis and infection of the cornea too .This organism during a traumatic event is usually inoculated into the eye and it usually does this via the foreign body introduced into the eye. Both local and system problems have been reported associated with B cereus and itââ¬â¢s been associated with medical foreign devices such as braces, prosthetic valves, and some invasive procedures like passage of urinary catheter, nasogastric tube and chest tubes. Some of the associated systemic problems caused by the organism include meningitis and encephalitis, pneumonia, osteomylitis, as well as endocarditis.The use of intravenous drugs also predisposes to infections by B cereus (Bean &Griffith 1990). The organism lives inside the soil and it is a common finding that it contaminates foods like rice (Jones and Blicslayer 2002). The toxins production usually occur when large amount of rice is prepared and then allowed to cool down which subsequently lead to the growth of the spores and the vegetative form now synthesize the toxins and all these occur in th e log phase growth period or during the process of sporulation.Clostridium is the third leading cause of bacteria food borne epidemics following salmonella and staphylococcus aurues The enterotoxin it produces causes a self resolving gastroenteritis and it does this by binding to the brush border membrane receptor and therefore binding to abdominal wall mucosa, interrupting the exchange of ion and the resultant effect is the loss of ions and low molecular weight metabolic products (Benenson 1990). The time of onset of the clinical manifestation is usually between 8 and 16 hours i.e. earlier than that of B cerues and it follows the ingestion of the organism itself. Although it is also associated with abdominal pain and diarrhea but less commonly with systemic problems. Another species of the clostridium family is clostridium difficile is usually associated with over 25% of antibiotic associated diarrhea and 95% cases of psedomembraneous enterocolitis and the organism produces two ent erotoxins (exotoxin A&B). Some of the precipitant antibiotics include clindamicin and ampicillin.However the diarrhea of B cereus infection does not follow antibiotics use. The clinical picture of C difficile diarrhea includes nausea, vomiting, abdominal pain as well as greenish voluminously large amount of diarrhea (Blacklow and Greeberg 1991). Protoscopy will show pseudo membranes and microabscesses with an erythematous mucosa and the diagnosis is confirmed by demonstrating toxins in the stool and the current treatment of choice includes oral metronidazole (Fricker etal 2007). Other aetiologic agents of food poisoningOther bacteria organism toxins that have been implicated to cause food poisoning include those of Vibro cholera, Yersina enterolitica, and Aeromonas species. However the exact role of the organism and their toxins in pathogenesis is not well delineated except for V cholerae. C perfirigens is another aetiologic agent responsible for food poisoning (Jones&Blikslaker 200 2). Case Study 1 Father, mother and 2 children with respective ages 34, 28, 6 and 4 presented in a hospital because of passage of watery stool and fever all of 6-12 hours duration.There was history of eating green salad beans, ground meat and tortillas prepared by someone else in an encampment because they are migrant farm worker family. It was also found out later that another 7 month old child in the family had not taken the food and was found to be well. The children started having abdominal discomfort, diarhoa and fever 24 hours later and the symptoms have been continuous since the previous 12 hours and both affected children have been having bloody stool.The parents also started having similar symptoms 5 and 7 hours ealier excluding visible bloody stool. There was history that some other persons in the encampment had similar symptoms in the past 2 weeks and that the campââ¬â¢s hygienic state is poor. Both children are warm to touch on examination as well as the parents and h ave increased heartbeat and the children also appeared to lack fluid . A mount of their stool revealed white cells that fight infections and the faeces of the children were blood stained. Comments and explanationGenerally speaking, vomiting, nausea, fever abdominal pain and diarrhea are the major key symptoms of infection of the gastrointestinal tract and the main symptom will depend on the cause whether it is a toxin or invasive or a combination of the two (Guerrant &Bobak 1991). Usually, nausea and vomiting are often related with preformed toxins in food. For instance, B cereus and staph aureus can generate enterotoxins in food and this usually happen few hours after the ingestion of the food substance (Guerrant &Bobak 1991).The likes of enterotoxins of enterotoxigenic E coli and Vibrio Cholera usually affect the superior aspect of the bowel to cause watery and massive diarhoea. As in the above scenario, invasive bacteria penetrate the colonic mucosal and cause abdominal pain with blood and mucous associated with fever and dehydration and this constellation of symptoms are regarded to as dysentery and the implicated aetiologic are for dysentery are:Entamoeba histolytica,Clostridium difficile ,enteroinvasive E. coli,salmonella ,campylobacter jejuni.The above children were admitted in the hospital and treated and parents were also treated as outpatients with fluids and drugs and this is followed by public health sanitary measures in the camp. In conclusion, food poisonings are very common most especially in the developing parts of the world with high morbidity and mortality most especially among infants and children (Kramer &Gilbert 1989). Therefore of value are public health preventive measures by the provision of good water supply as well as sanitary and hygienic water and food supply.(Guerrant RL, Bobak DA: Bacterial and protozoa gastroenteritis. N Engl J Med 1991; 325:32). Case study 2 A reported incidence of acute gastrointestinal infection occurred in Ju ly 21, 1993 among the members of staff as well as the pupils of a co-owned child day care school after a catered lunch. This lunch was served for eating to 82 pupils of the day care centre to children between the age of 6 and less and the children are 82 in number along with 9 staff members. Past dietary history was gotten from 80 individuals and 67 were said to participate in the lunch.An individual at the day care made a case definition of vomiting. Among those served and who ate at the lunch, 21 %( 14) became sick and 13 did not. The symptoms observed ranged from diarrheal in 14 %,pain in 30% case and nausea in 71% case. 12 out of the 14 instances occurred among the children from ages 2. 5-5 and 2 other members of staff. Stastical analysis reveals that the median incubation period was 2 hours(the range is 1. 5-3. 5 hours). The resolution of symptoms took place over median interval of 4 hours following the onset(range 1. 5-22 hours).Among the dishes served in the local restaurant, only chicken fried rice was linked with notable illness and the problem occurred among 14(29%) out of the 48 individuals who ate the chicken fried rice in comparison to none of the 16 individuals who did not eat. The implicated rice was prepared the night preceding the incidence on July 20 under room temperature before it was refrigerated. The report also confirms that the rice was heated in oil with the slices of the cooked chicken on the morning of the lunch, then handed over to the daycare centers at around 10:30 am without refrigeration and served at noon without rewarming it.As a subsequence to the outbreak the advice by the health personnel to the restaurant officials and daycare staff was to stop the custom of cooling of rice or any other food at room temperature henceforth and that food should be kept at appropriate temperature of 5 degree or above 60 degree and that the temperature should be confirmed by a thermometer. Analysis of the case study 2 This short incubation syn drome variety of the disease which featured in this outbreak is overseen by highly stable toxin that can withstand enzymatic effect as well as extremes of temperature and PH.The diarrhea syndromic type is mediated on the other hand by an acid and heat labile intestinal toxin affected by the effect of the proteolytic enzymes like pepsin, trypsin etc. To make a diagnosis of Food poisoning, it is essential to isolate more than 10 5organisms per gramme from the epidemiologically implicated food substance . The self resolving as well as the lack of severity in most cases account for the reason B cereus is underreported(qtd in Todar 2004). Moreover recent research reveals that close to 20 % public health laboratory do not have the facility for the routine test for B cereus.In the United States, the leading cause of the emetic syndrome type or the ââ¬Å"Short incubation syndromeâ⬠type of B. cereus is fried rice. As discussed before that B cereus more often than not is found in uncoo ked rice where the heat resistant spores also withstand and survive cooking. The survival of the vegetative form is a possibility after cooked rice is placed in an incubator as it generates heat stable toxin substance which can withstand heating(Kramer &Gilbert 1989). In this described scenario, the vegetative form must have proliferated at the food joint and also at the day care centre while the rice was being kept at room temperature.The problem is the unawareness of the restaurant food workers that certain danger is associated with cooked rice potentially. Itââ¬â¢s imperative from the report the need to properly inform food handlers about fundamental rules and customs for hygienic healthy and safe food management and handling (Benenson 1990).
