Durga Puja Essay

One of the biggest social events of India, Durga Puja is considered the main festival for Bengalis. It is a ten-day carnival in West Bengal, the eastern state of India. Magnificently created puja pandals are erected at every other street of Kolkata, the capital city of West Bengal. Every pooja pandal is unique in its own terms, with beautiful patterns that are true delight to the eyes. A spurt of fanfare can be sensed all through the ten days, especially on the last four days of the festival. Bengalis in the metro city rejoice to their heart’s content. They consider the festival as a wonderful occasion to reconnect to their family and friends. The air is filled with festivity, during the season. In the following lines, we have provided information on the celebrations of Durga Puja in Kolkata. Durga Pooja Celebrations In Kolkata Preparations The preparations of the festival commence one or two months in advance. Puja bonus (extra money apart from the salary) is given to the employees of both government and private organizations, in Kolkata, since the bread-winner of the family brings in clothes and furbishes for the home, during the festive season. Pre-pooja bargain sales are displayed by shops, as they cash in a lot during the festival. Every household prepares itself to welcome the season, with great enthusiasm. Pre-Puja Celebrations Celebrations of the festival start with Mahalaya, the first phase of the waxing moon in Aswin. During the time, about thousands of people offer prayers to their ancestors at the city’s river banks. This ritual is referred to as ‘Tarpan’. The festive mood builds up in the people, when Dhakis (drummers) belonging to the countryside start gathering near the city. The local Puja organizers are attracted by the feathered drums played by the drummers. Making Of Idol While the festival was celebrated within the families some times back, it has taken the shape of a community festival, celebrated at Puja pandals. The  construction of the deity of Goddess Durga and other gods start a couple of months prior to the festival. A place in the north Kolkata – Kumartuli is famous for the production of beautiful idols made of clay. This is the region, where expert artisans show their dexterity of making idols of Goddess Durga, the demon Mahisasura, Lord Kartik, Lord Ganesha, Goddess Saraswati and Goddess Lakshmi, required for the festival.

Article Critique Essay Example for Free (#2)

Article Critique Essay The author of this article is a Canadian who has raised the alarm on the increasing number poverty stricken people hence springing up of ghettos in big cities. The author rhetorically is asking a question whether there are ghettos in Canadian cities. The author is coming up with many ghetto synonyms but yet they are of not the same meaning. The name like enclave sound more ethnical and it has been described as a grouping of people from the same ethnic group living in a low income earning or a poor neighbourhood. The article pinpoints that in the year 2001 families residing in high poverty levels doubled the year 1981. The message in the article is directed to the authorities in these cities to get warned of a looming crisis and look for ways to alter the trend. The message is not has to any group that it mentions that is the people from the enclaves and the ghettos. The article has outlined many causes of ghettos in Canadian cities. Poverty has been rated as the number one cause and this article gives figures from the research to substantiate its claim. The exact time is given when immigration policy of Canada was changed and the change swung Canada into a cultural and social crisis or socio cultural crisis. According to the authorities and the research that has been carried out immigration puts Canadian cities on spotlight of having many poor neighbourhoods. The author also makes a comparison between Canadian and American cities whereby Canadian cities are going more enclave than ghettos in America. In American cities the traditional definition of a ghetto is a residential district that concentrates racial Enclave tends to collect people of the same ethnic background together while ghettos collect poor people from various ethnic backgrounds. In both cases, people involved are affected by poverty and low income level. From one of the researches that have been done, the article reveals that an alarm was raised about the growth of neighbourhood poverty in Canada. The article pinpoints groups of people who make up the population who end up to the ghettos. Their background is partly covered by poverty and the article further expose that these are immigrants from Asia, Africa, West Indies and Latin America. The research that was conducted showed that between 1971 and 2001 is the period when the majority of the Canadian population was born in the back mentioned countries. Nevertheless, some cities like London there are no ghettos and this is due to the efforts of the councils. However, I take the article head to mention that it does not clearly outline and show the consequences of the increasing population in ghettos and mushrooming of ghettos and enclaves. In many a times these nighbourhoods have been associated with crime and drugs. Does is it mean the researches that were conducted didn’t capture these common phenomenon that is associated with ghettos? Furthermore, the article does not highlight any ways that have been adopted to combat the expanding ghettos and enclaves without necessarily disrupting the social cultural set of these people in the ghettos.

An Investigation into A Particular Operation on a Set of 100 Numbers Essay

An Investigation into A Particular Operation on a Set of 100 Numbers - Essay Example (Determinants and Cramer's Rule for Linear Equations, Undated) Both A and B are square matrices and thus the laws of determinants are applicable to them. Definition: There is no stand-alone definition of a determinant but it is defined in terms of a series of matrices as is evident hereafter. The determinant of an n x n matrix is defined as a sum of +/-1 times determinants of (n - 1) x (n - 1) matrices. (Determinants and Cramer's Rule for Linear Equations, Undated) Now that the technique of calculating determinants of matrices of any order has been somewhat explained a singular property of A is being touched upon. A's Singularity Any 2 x 2 matrix derived out of any set of numbers in adjacent rows and columns of A has the same determinant. Example: Suppose, E = 78 79 88 89 Then, DetE = (78 x 89) - (79 x 88) = 6942 - 6952 = - 10 This proves that all determinants of 2 x 2 matrices comprised of numbers in adjacent rows and columns are the same (-10) in the large 10 x 10 matrix A. This allows a general formula to be derived for the terms of all such matrices where N is a 2 x 2 matrix within A. N = n n+1 n+10 n+11 Here the numbers in the left diagonal - n and n+11 - have a periodicity of 11 while the numbers in the right diagonal - n+1 and n+10 - have a periodicity of 10. This is true of all 2 x 2 matrices comprised of numbers in adjacent rows and columns within A. And, detN = [n(n+11) - (n+1)(n+10)] = ( + 11n) - ( + 11n + 10) = - 10 This singularity gives rise to another that is mentioned in the calculations section and these two will make it easier to calculate the determinant of A... For an n x n matrix if the 'i' order row is considered and the (n-1) x (n-1) matrix derived by crossing out the row and the column is also considered then the determinant of the original n x n matrix is as below. For the matrix A it is noted that all values of , where 'i' is the 1st row and the matrix is a 2 x 2 one, is -20. It is considered for the essay that is the difference and not the true determinant value. This assumption is now being checked out in the essay for any term. Thus, for calculating the value of the determinant of A it is also found that the value ofis alternately negative starting with the second term. This makes it extremely easy to calculate the required value. Also, the operation has to be on a (n-1) x (n-1) matrix - a 9 x 9 matrix, as mentioned in the formula. This signifies that all numbers from 1-89 have to be considered. It is noticed on the right hand side of the equation that all even numbers are negative and all odd numbers are positive. Using the summation formula for series' in arithmetic progression - n/2[2a + (n - 1)d] - where n is the number of terms in the series, a is the first term and d is the common difference. (Arithmetic Series, MathWorld, 2006) The singularities revealed by the investigation allows us to determine that any square matrix of any order n x n constituted of the particular sequence of numbers belonging to the set of all positive numbers starti

French Revolution During 18th Century Essay Example | Topics and Well Written Essays - 2000 words

French Revolution During 18th Century - Essay Example (Lind Frey, 2004) The immediate cause of revolution was financial crisis that originated due to war in America that was financed through borrowing by Necker and same method was adopted by Calonne to pay off the arrears which increased the deficit. Fiscal administration was so confusing that the rough analysis of financial statements of March 1788 of Old Regime budget estimated expenditures at about 629 million livres and receipts of 503 million leaving behind the deficit of 126 million or 20% which was attributed to court wastefulness and financers profit. The emptied treasury resulted in cutbacks of pension and stockholders Bank of Discounts were made legal tender. (Georges Lefebvre, Elizabeth Moss Evanson and Paul H. Beik) Ronald Schechter presents the argument of Furet wherein it is mentioned that the revolution of 1787 marked the first capitulation of the state to the demands of the sharing the power between the administrative officials and elected representatives of third estate s. (Ronald Schechter, 2001) Kings under capability of handling the situation of crisis after the war made him a weaker leader. Louis XVI was not able to control the deficit and adopted the same method that Necker used to finance the war in America. And moreover the new taxation policy by imposing the tax on elite groups like notables, and other merchants ignited the sense of revolt among the Third Estate members to which they disagreed. These factors sparked the beginning of revolution in France. The revolt from elite groups created an excitement among the commoners, notably lawyers and they supported the nobles in revolt against king even though he was authorizing them to plead his case. The Patriot Party was formed which provoked counter argument using brochures with cautious... This essay describes the French Revolution, that was the major event during the 18th century that shook the entire world and economy of France. It laid the foundation for human rights through Declaration of the Rights of Man which provided equal status to poor and downtrodden on par with nobles and clergy. It was the Estates General meeting called by Louis XVI to elect the deputies that led the revolt among the Third Estate. The revolt intensified when Third Estate broke the stalemate and spread the revolt across France inviting First and Second Estate to join the rebel. The peasants’ war broke out resulting in loss of human life. Aftermath of the revolution, the French government implemented various provision and policies to cope with the economic crisis. The French revolution had various effects in forms of economy, society, political and religion. There were no differences maintained in the state school and government authorized the positions of pastor and bishops. France r eceived dramatic response from neighboring countries in the form of war including America. It also promoted nationalism which was also adopted by Italy and Germany under Napoleon and influenced most of the European countries to adopt parliamentary democracy. Such was the impact of the revolution that evolved the democratic form of government which is followed almost by all the countries in world today giving equal rights and opportunity to each and every citizen irrespective of race, religion, social and financial status.

Organizational bahavior Business (MBA) - Essay Example 45). The key to managing a diverse workforce is increasing individual awareness of and sensitivity to differences of race, gender, social class, sexual orientation, physical ability, and age. The locus of change is the individual and change itself is both intra- and inter-personal. This approach is consistent with the preponderance of diversity initiatives undertaken in organizations, which primarily comprise training and development efforts such as diversity awareness training, leadership training, mentoring, and personal support group (Cope 2000, p. 76). A strict code of ethics and social corporate responsibility will ensure that the company value all stakeholders and ensures fair treatment of all groups. Ethics and SCR will ensure high high-standards of performance and ethical norms followed by all employees. The system of inquiry will help to incorporate specific references to such topics as new legal and ethical dimensions, and SCR (Frederick 2000, p. 5). It should be framed so that it is easy to derive from it policies on these and other aspects of conduct at work. It also will provide a basis on which to build training on such problem themes in a way which is convincing even to people who might otherwise consider them to be matters only for campaigning special interest groups (Frederick 2000, p. 23). It is the role of management to act as important activity and to co-ordinate, direct and guide the efforts of members toward the achievement of goals and objectives (Dubbink 2003, pp. 3, 7). Within this process ethics and ethical c ode has a great influence on organization and decision making process as a part of management. the company can donate some money to local church or healthcare organization, finance non-for-profit organization or support R&D activities. The company should consider social issues and environmental influences in making investment decisions (Dubbink 2003, p. 42). Employees, their work safety and health are the main priority. It is important to improve working conditions and introduced health related programs for employee. Also, it is vital for the company to take actions and decrease GHG emissions and negative impact of production on the environment. Question 2 In general, the level of successful performance of a team is influenced by successful or unsuccessful decision-making process, because it involves full discussion and participation. This appears to work best where a high level of interaction is required among all members of the group in order to solve complex problems. The main factors which imperative to effectively measuring the successful performance team performance are team dynamics and cohesion, common language and shared understanding (DeMarco and Lister 1999, p. 45, 52). Also, it is possible to single out the level of professionalism and leadership qualities of a leader (DeMarco and Lister 1999, p. 155). "A team leader should bear in mind that low dynamics prevent teams to produce a higher level of output"

Baha'i - distinct, universal religion Essay Example | Topics and Well Written Essays - 1000 words

Baha'i - distinct, universal religion - Essay Example In accordance to Bahaullah, God had set historical forces which were collapsing conventional and customary barricade of ethnic group, rank, article of faith and nation which would help to give rise to universal civilization. The main challenge confronted by the humanity is to recognize and acknowledge unification and to assist in its promotion. Bahaullah gave particular emphasis on the issue of bias and partiality. The heart of his message was to call for communal harmony and companionship among different and diverse states, cultures and people (Perkins & Hainworth, 30). Three primary teachings constitute the foundations for Bahai teaching and doctrine which are the oneness of God, unification of religion and unification of entire humanity. God’s message is revived and revitalized in humanity through the use of several people. These people have the wisdom and guidance to improve the morality of human beings. Religion is an evolutionary process according to the Bahai faith as the requirements of the different ages stress the need for moral schemes. The Bahai faith describes God as beyond understanding and considered to be a great entity. The Creator is Greatest and the creation cannot know about Him because there is something that surpasses the grasp of human mind. To assist human beings so that they learn about God’s nature, manifestations are sent to them (Miller, 65). The Bahai faith incorporates the belief that God send these manifestations to instruct and alert humanity. The Bahai writings in particular recognize Abraham, Moses, Muhammad, Zoroaster, Buddha, etc as manifestations (Miller, 84). Bahai Faith claims that God is the creator of the world and everything present within it is His reflection and attribution. The Bahai scriptures define the human soul as eternal and have characteristics of all God’s qualities but these qualities live only potentially until and unless they are developed.

Political Action Awareness Research Paper Example | Topics and Well Written Essays - 500 words

Political Action Awareness - Research Paper Example tempts, the basic philosophy of health has not changed, and these measures have been viewed as an inside erosion of the core principles of caring that attracted many professionals to health care initially. Given the values of policy-makers and senior managers of the quasi-market, health care workers found that their practices were molded into a culture that presented them with legislative and ethical challenges. Ethical issues such as promotion of narrow policies, inadequate qualified staff to provide health care and the obligation to follow poorly outlined strategies (Finkelman & Kenner, 2013, 245). Therefore, it is the health professionals’ responses to these issues that will set the scene and write the script for better services in the health care sector of the economy. Despite the presence of collaboration in the various health disciplines, and the shift of balance of power from a medical supremacy to a mutual viewpoint, none of the professionals involved in health care have ownership in the care service they offer. Public health services are owned by funding from the government, and thus professionals involved in the service have no effective voice. Political and professional courage is a necessity amongst managers and nursing leaders so as to steer nursing towards eradicating people’s dualism to individual against collective health and improve social health services. Activist nurses, with an informed vision, can play a significant role in improving the level of discourse in the society. Managers or leading nurses need to outline the conditions for work so that nurses have the responsibility and rights to act as political individuals in national and local arenas. Nurses ought to have a system that moves from being away from people’s daily experience to one that offers resources to policy-makers and the community. For excellent policy making to occur, leading nurses as interpreters and advocates of science must feel sanctioned to support their health

Benevolent God and Problem of Evil Essay Example | Topics and Well Written Essays - 1750 words

Benevolent God and Problem of Evil - Essay Example This paper is aimed at answering the question: â€Å"Is the presence of evil in the world compatible with the existence of a benevolent God?† Problem of Evil has been one of the greatest challenges to the existence of a benevolent God. It is argued that if God is benevolent, omniscient, and omnipotent, then why does evil exists in the world. In order to do this Problem of Evil and the possible responses to it are discussed. The responses are analysed to see if they are satisfactory and allow for an existence of a benevolent God and evil. Problem of Evil The fact that evil continues to occur in our world contradicts or challenges the existence of a benevolent God. If God is benevolent, along with being omnipotent and omniscient, then God must be good and kind to everybody. This means there must be no evil in the world which causes enormous suffering and pain to not just humans but all living beings. But this is not true. There is evil everywhere in the world and all beings are subjected to suffering and pain. Therefore, the existence of a benevolent, omnipotent and omniscient God and the presence of evil contradict each other. A benevolent God who is also omnipotent and omniscient must not tolerate such widespread evil and must eradicate it. If God is omnipotent and omniscient but does not eradicate the evil in the world means that God is no benevolent. On the other hand, if God is benevolent but still not eradicates evil means that God is either not omnipotent or omniscient. But there are people who believe that God is benevolent at the same time acknowledging the fact that there is evil in the world. This belief is very inconsistent and many have addressed this issue. Responses to Problem of Evil There are numerous responses from theologians and believers of benevolent God to the question raised about the problem of evil. Many have tried to solve this problem and find a solution that would put the argument of ‘Problem of Evil’. There aren’t any solutions and reasons that are perfectly logical. In fact, many proposed solutions are proven to be fallacious. But at the end it all comes down to faith. Those who do not believe in God go with the argument that questions the existence of God while those who believe in a benevolent God accept that reasoning given by theologians irrespective of logical shortcomings (Mackie, 1955). Following are some of the responses by theologians and theists to ‘Problem of Evil’: Evil is Necessary as a Counterpart to Good This is one of the most popula r responses that are used. For good to be present there needs to be evil. Evil is very essential for us to recognise the good that is around. Good is a counterpart to evil and the absence of one makes the other one irrelevant. The idea here is that if there was no evil then good would not make much sense. It is only with respect to evil that we can decide what is good and what is not. This can be best understood with the example of light and darkness. We can make the distinction between light and darkness only because we are aware of the two. If either one was absent, then there is no

Does the Internet Have a Negative Effect on Youth or Does Its Use Need to Be Monitored More Essay Example for Free

Does the Internet Have a Negative Effect on Youth or Does Its Use Need to Be Monitored More Essay Does the internet have a negative effect on youth or does its use need to be monitored more? The Internet has become a major part of everyday life for most Americans especially today’s youth but some say that internet has a negative effect on youth more than a positive one. The question is: are all of the effects of the internet negative? The internet is used by most youth for entertainment, to find information and to connect with people. Unfortunately while the internet can be useful it has been known to cause negative effects on children. Social networking sites are very popular among today’s youth. In recent years cyber bullying has become a trend among youth because of the internet. There are also cases that youth have been exposed to inappropriate websites while on the internet and it had a negative effect on them. The internet has been known to cause a negative effect on youth but it can be prevented if their internet use is monitored. Social networking websites that are popular on the internet Twitter, MySpace, face book and YouTube. It is said by some that youth spend more time on websites like these than studying and doing their homework. While most of the young people in the study got good grades, 47 percent of the heaviest media users, those who consumed at least 16 hours a day, had mostly C’s or lower, compared with 23 percent of those who typically consumed media three hours a day or less (New York Times). Some youth can spend all day on social networking sites. Often times social networking sites can also become a distraction to youth. Most youth would much rather get on face book or twitter than study or write a paper. Most of the time youth can begin writing a paper but end up spending hours on face book. Social networking sites also have been known to cause children to be kidnapped or raped. Because of the amount of information that can be put on these sites it is easy for them to be tracked. There have also been cases where youth have chatted someone under the impression that they were someone else. There have been several cases where children have been harmed because someone found them on social netwo rking site. This can only be prevented if youth internet is monitored. So it seems that social networking sites can only have a negative effect if the time they spend on social networks is not being monitored correctly. Cyber bullying is another negative effect from the internet. Cyber bullying is using the Internet to  send or post texts or images intended to hurt or embarrass another person. It has been said that forty-three percent of teens have been victimized by cyber-bullying in the last year (ncpc.org).Cyber-bullying is a result of youth being mad at another peer or just trying to have fun. Cyber-bullying has been said to cause depression and sometimes even suicide among youth. It has become a major problem among youth in recent years. A lot of the time cyber bullying takes place on sites like twitter, face book and sometimes even YouTube. There have been cases all over the news where youth have said that they became depressed because of cyber-bullying.Most youth who have participated in cyber bullying thought that it was funny and not realized that it would have a negative effect on the victim. There have been steps taken to try to prevent cyber-bullying but there are still some cases where it is still happening. Cyber-bullying can be prevented if t he internet use is being monitored. Almost eighty percent of teens said they did not have rules for the internet or that it was not monitored. While browsing the internet the youth can be exposed to a lot of inappropriate websites that most would agree they shouldn’t be exposed to. Twenty five percent of youth had unwanted exposure to sexual pictures on the internet in the past year, challenging the prevalent assumption that the problem is primarily about young people motivated to actively seek out pornography according to youth and society (Protectkids.com).One quarter of these youth were upset by being exposed to pornography. In other cases when youth are exposed to pornography they become interested and begin watching it regularly. According to one study, when youth under fourteen years of age are exposed to pornography it is related to greater involvement in deviant sexual practice, particularly rape (protectkids.com). It has also been said that because pornography encourages sexual expression without responsibility it endangers children’s health. If a child were to see porn he/she may think that is okay to have unprotected sex which could then lead to std’s and unplanned pregnancy( protectkids,com ). Although porn can and has had negative effects on children it has been said that porn does not always have negative effects on children. Some children are exposed and it has no effect at all. In the end it seems that it may depend on the child if it has a negative effect or not. It also seems that the only way that this can be prevented is if their internet use is monitored. There are strategies that  can be taken to do this (Council). It seems to be proven that the internet can in fact have a negative effect on youth. Social networking sites can cause youth grades to drop. Cyber-bullying mostly takes place on the internet and it cause youth to become depressed. Youth can be exposed to several inappropriate websites which can damage their future development. The internet can be a very useful tool for youth to have access to but it can also have a very negative impact on youth if it is not monitored correctly. To ensure that the internet does not harm our youth in negative way parents/guardians must monitor their children’s internet use.

Entomotoxicology in Forensic Science

Entomotoxicology in Forensic Science ENTOMOTOXICOLOGY: A POWERFUL TOOL FOR FORENSIC SCIENCE For many years, forensic science have known that insects and their larvae hold answers to deaths that are not quite clear in terms of their actual timeframe or situations surrounding them. Now, a branch called entomotoxicology is helping those who work in forensic science find new answers to the questions that have remained in certain cases. This paper examines the role and science behind the advancing field of entomotoxicology in which toxins and drugs can be measured in the insects and larvae that infest even the most decomposed body. Before understanding this branch of forensic science, it is important to understand how bodies decompose and how insects become a part of the transformation of a human body once the person has died. It is important to study the decomposition process as part of a crime scene because it helps determine the victim, how they died, and when and where they died (Vass 2001: 192). Other factors, such as the presence of melanin can help investigators find out the race or ethnic background of the victim (Vass 2001: 192). Additionally, â€Å"knowledge of any trace amounts of chemicals, drugs, medications or toxins present in decomposed tissue may also be of help to investigators in attempting to determine the cause of death† (Vass 2001: 192). Having said that, it is then important to understand what is generally involved in the decomposition process. The start of the decomposition process has been clocked down to four minutes after death has occurred (Vass 2001: 190). The putrefaction process is where the body’s soft tissues are destroyed by micro-organisms, such as bacteria, fungi and protozoa (Vass 2001: 190). Part of what happens to a decomposing body is a mummification process (Anonymous 2007: 2) that is called adipocere, which is â€Å"insoluble fatty acids† that are left behind from â€Å"pre-existing fats† that forms within a month of death but can remain as part of the cadaver for literally centuries (Wikipedia 2007: 1). Created from bacteria that convert a body’s fat, adipocere is the formation of soap from this fat is also known as saponification and appears in the form of a â€Å"yellowish-white, greasy, wax-like substance† (Voss 2001: 190). This substance can slow the growth of bacteria and can protect the body from further decomposition (Wikipedia 2007: 1). Adipocere also â€Å"forms through hydrolysis† so it is more common in humid environments or when a body is found underwater (Wikipedia 2007: 1). It is also interesting to note that adipocere also seems more common on corpses that are clothed in synthetic materials versus natural materials, such as cotton (Anonymous 2007: 3). Additionally, soils that are highly alkaline contribute to adipocere formation (Anonymous 2007: 4). This is because the alkaline source hydrolyses the corpse’s fat, turning it into the aforementioned soap-like substance (Anonymous 2007: 4). The deposits of adipocere are beneficial in determini ng the weight of an individual, which may then lead to the identity of that person (Vass 2001: 192). Insect activity, including laying eggs, eventually becomes part of the process – sometimes as soon as the onslaught of rigor mortis (Anonymous 2007: 2) – and leads to a significant decline in the condition of a corpse (Vass 2001: 190). Injuries, such as wounds and other instances where the dead person previously bled before dying can increase the onset of insects and bacteria (Voss 2001: 1919). Along with adipocere in a decomposing body comes the infestation by maggots and bugs, which are interrelated due to the amount of adipocere and climate conditions of the area where the decomposing body is located. Insects – especially arthropods – have played a significant role in forensic science because they, including larval and mature forms, like to feed on organic substances (Tuzun and Acikgoz 2007: 1). They feed on wounds and decomposing bodies, subsisting on â€Å"the nostrils, sinuses, stomach, bowels, ears, vagina and anus part from the skin† (Tuzun and Acikgoz 2007: 1). Forensic entomology has been used for years to help calculate the time of death of a body as well as â€Å"who was the killer, whether a killer had been in a particular spot or not, which was the murder weapon, in what manner a person had been killed and so on† (Aggrawal 2001: 1-2). The exact science really uses an estimate of â€Å"the period of insect activity on the dead bodyà ¢â‚¬  (McKenna 2003: 3). There can be outside factors, such as â€Å"weather conditions, placement or concealment of the body, or other factors† that delay the arrival of insects (McKenna 2003: 3). For example, one noted forensic scientist who specialises in studying insects on bodies pointed out that â€Å"insects will begin to colonize an exposed body within minutes following death† in warm climates like Hawaii but may take longer to appear in more temperate climates (McKenna 2003: 3). However, what becomes hard to gauge is the effect of substances, such as heroin and cocaine, play on a person because it can be difficult to measure the toxicity level of these substances in the body once blood and certain tissue is no longer in a form to be accurately analysed (Tuzun and Acikgoz 2007: 1). Sometimes, it is not clear whether or not there might have been an â€Å"accidental or suicidal consumption of toxic substances† (Tuzun and Acikgoz 2007: 1). For example, in researching the subject of entomotoxicology, it is clear that it is only in recent years has it become a well-utilised facet of forensic science. An article from a 1998 Journal of Forensic Science had a case that described the suicide death of a heroin addict (Benecke 1998: 3). While the body showed signs of masses of eggs that were first and second generation cheese skippers, which helped the forensics team that the woman had been dead about four months, there were other unanswered questions in regards to the level of heroin in her body (Benecke 1998: 3): â€Å"This case indicates that P. caset does not shorten its development significantly under the influence of heroin as was observed for some arthropods. However, the exact concentration of heroin could not be determined because of the severe decomposition† (Benecke 1998: 3). In a similar case with another heroin addict, those investigating the death admitted that the â€Å"influence of drugs in corpses to the insects feeding on them is still in progress† and there was still no conclusive way to indicate the quantity of drugs in the body of the drug user (Benecke 1998: 5). This is where the relatively new science of entomotoxicology becomes an important and vital way to find solutions to certain cadaver issues related to drugs and toxins. Going beyond just studying the insects found on corpses to gain insights into what may have happened to a person, entomotoxicology includes â€Å"the post-mortem toxicological analysis of carrion-feeding insects in order to identify drugs and toxins present on intoxicated tissues† (Tuzun and Acikgoz 2007: 1). This branch of forensic science â€Å"also investigates the effects caused by drugs and toxins on arthropod development in order to assist the forensic post-mortem interval estimates† (Tuzun and Acikgoz 2007: 1). What happens is that â€Å"insect larvae eat the flesh of a person and based on the drug content of the insect, drug intake of descendent can be determined† (DeBoeck, Wood, and Samyn 2007: 14). The drugs or toxins become concentrated in the body of the insect tissue and may stay ther e based on the level of concentration from the cadaver (McKenna 2003: 4). As a particularly effective tactic during the autopsy stage, entomotoxicology is an incredible process that puts the amazing powers of insects to work: Diptera and other arthropods can be reliable alternate specimens for toxicological analyses in the absence of tissues and fluids normally taken for such purposes. Insects can be analysed quite easily after homogenisation by common toxicological procedures such as radio-immune analysis (RIA), gas chromatography (GC), think layer chromatography (TLC), high pressure liquid-mass chromatography (HPLC-MS) and gas-mass analysis (GC-MS). (Tuzun and Acikgoz 2007: 1). Previously, the methods used were â€Å"time-consuming and labor-intensive† (DeBoeck, Wood, and Samyn 2007: 5). The new methods incorporated into entomotoxicology utilise tandem mass spectrometry and multiple reaction monitoring to identify low levels of compounds â€Å"in complex biological matrices† (DeBoeck, Wood, and Samyn 2007: 6). Diagnosis allows for an actual analysis of the â€Å"metabolites of drugs† and helps differentiate â€Å"between prescription and non-prescription derivatives of drugs† (DeBoeck, Wood, and Samyn 2007: 6). To better understand how insects that have ingested toxic human flesh can help forensic scientists, it is best to examine a specific experiment that utilised the Black Blow Fly which had ingested Carisoprodol, a muscle relaxant sold by prescription only (Monthei 2007: 1): Even though Carisoprodol had no effect on the fly’s life cycle, the experiment is significant because a carbamate like Carisoprodol has not been tested before in this manner. This experiment could be done with another species of fly and have different results. Also, another person doing an independent study could take the maggots that I collected and determine if Carisoprodol accumulated in the maggots or if a metabolite of the drug is present. The presence of Carisoprodol would be significant to a toxicologist because if a body found at a crime scene was devoid of tissue, the toxicologist could use the maggots to determine if the deceased had Carisprodol in his or her system. My study showed that a forensic entomologist would not have to adjust the PMI based on the presence of the drug because this insect’s life cycle is not changed due to the drug (Monthei 2007: 1-2). Similarly, if a person was killed by morphine and the body ended up becoming infested by maggots during the decomposition process, the morphine can now be detected by analysing the maggots and the larvae (Aggrawal 2001: 1). What’s interesting is that, as the maggots â€Å"metamorphose into pupae, this morphine gets incorporated in their walls (Aggrawal 2001: 1). This means that, even years later, a skeletonised body could be tested and found to have died from morphine by testing pupae shells around the skeleton since morphine is impossible to detect by studying human bones (Aggrawal 2001: 1). The book entitled, A Fly for the Prosecution, goes into great detail explaining how entomotoxicology works. The author describes a paper published in 1990 by Pascal Kintz that describes how he tested for five drugs in both a cadaver’s organs and the maggots that were found and while the organs only tested positive for four of the drugs, the maggots had all five, including an insecticide known as malathion (Aggrawal 2001: 3). Interestingly enough, â€Å"in the case involving malathion, his conclusions regarding the time of death were a bout five days, while other evidence was pointing towards eight days†¦.Malathion had failed to kill the maggots†¦but had delayed their maturation by 3 days (Aggrawal 2001: 3). The level of malathion would have killed them if they had been adult flies instead of maggots (Aggrawal 2001: 3). As forensic science progresses, more advancements have been made, particularly in the areas of DNA technology and entomotoxicology. In terms of DNA advances, this tactic has enabled forensic scientists to more quickly identify â€Å"early instars of the Diptera larvae, eliminating the need for time consuming rearing of the larvae to the adult stage† (McKenna 2003: 5). Additionally, â€Å"the effects of various drugs and toxins on maggots development have demonstrated the need to include these in the estimations of the periods of insects development on a body when estimating the post-mortem interval† (McKenna 2003: 5). This is just some of the many examples available on how this new area of forensic science is providing more answers for those doing autopsies or studying crimes. While insect evidence as part of forensic study became more credible in the 1980s, it has slowly become more accepted rather than having maggots removed from a body to reach the â€Å"real evidence† (McKenna 2003: 4). Now, the role of entomologists and law enforcement are becoming more comfortable with each other as the number of cases are indicating the amazing finds of both straightforward entomology forensics and entomotoxicology in particular cases. Adding the use of insect toxicology as a scientific tool to their other capabilities allows the forensic scientist to uncover further clues that might have previously gone unnoticed due to their inability to gather the evidence from a badly decomposed corpse or from mummified or skeletal remains.

Are You Experienced? :: essays research papers

The Jimi Hendrix Experience released its first album in early 1967. Popular music had been leaning towards psychedelics for a couple years already and Are You Experienced? came out at about the same time as the Beatles' Sergeant Pepper's Lonely Hearts Club Band. Are You Experienced? far exceeded the Beatles' triumph in complexity, capturing the essence of the late 1960's culture. Naturally the newer band did not share the immediate success of the Beatles. But its staying power has been testified to by several generations. The British version of Are You Experienced? contained a few subtle differences. Most prominent were the absence of "Purple Haze" and the addition of Hendrix standard "Red House". "Purple Haze" caught fire in America after the Monterey Pop Festival and became Jimi's signature song. Although it was said to have endless verses, Jimi generally sang only the shortened version from the album (with a few ad lib changes). The single was sent to radio stations with a note: "This song was intentionally distorted. Do not adjust." Are You Experienced?, as with most of the Experience's music, sounds heavy no matter how many times you listen to it. In actuality, the stony "Purple Haze" is about as close as they ever come to hard rock. The next song, "Manic Depression" comes in strong with the opening chords and then reveals Mitch Mitchell's trademark rolling drums. It also contains another of Jimi's solos worth listening to by any new or Experienced fan. Chas Chandler chose the quietest song on the album to give the world its first taste of Jimi Hendrix's talents. Its first single, "Hey Joe", a song written by turn-of-the-century bluesman Billy Roberts debuted at number on the pop charts. No other song written or performed by Jimi Hendrix had as much success as this one. It topped out at number 2, behind the Beatles' "Lucy In the Sky With Diamonds". When there are other people around, it makes you feel alive. But when you sit alone and listen to the music, every chord catches in your throat. "Love or Confusion" has happened upon me more than once when I was suddenly realizing the dispair of yet another relationship. If the answer to his question is not obvious during the song itself, Jimi answers it for you with his very last whisper. "Love or Confusion" is a wicked twister of emotion. It shakes you up and when you lose your sense of direction, it drops out from under you, leaving you to fall mercilessly to

Summer at the Cabin :: Descriptive Essay About A Place

Summer at the Cabin The cabin was built in the 1950's when my Great Grandpa rode up there, and it looks like not many repairs have been made since that time. The cabin is about 15 feet by 20 feet, and is made out of pine logs. There are places where you can see between the logs because the chinking is falling out. The cabin faces to the east. It has a small porch that was made by leaving the first four logs of the cabin about six feet longer than the rest. There is a small set of corrals in front of the cabin. There is an old shed to the north of the cabin, and the outhouse is behind it. The porch has a hole in it where a horse stepped through it when someone forgot to put the chain across the doorway. In the rafters hang old horseshoes that we tack on when one of our horses loses a shoe. Half the porch is cluttered with tools, shovels jacks, chains, shoeing equipment and an axe. The other half is full of firewood. The only electric thing in the cabin is the phone. Propane or wood runs everything else. There is only one propane light in the cabin. To light the rest we use Coleman lanterns. There isn't any running water in the cabin so we have to haul water. The floor to the cabin is made out of scrap lumber. It used to be rough, but has been worn smooth with time. There are places where it has rotted out and has been patched. There are also places that have been burned by sparks from the two stoves, and people spilling the ashes. Inside the cabin, behind the door, is a long bench we stack pop, canned stew, and many other things on. In the corner is the dog food, which we keep inside so the squirrels and birds don't get it. However that doesn't stop the mice. At night you can hear them run across the floor and into the sack. We trapped mice for three weeks before we stopped hearing them at night. A large hand made table is pushed against the left wall of the cabin. This is where we eat and play cards. I also sleep under the table at night because it is the only open space. At each end of the table is a homemade chair, and for the length of the table is an old bench.

Ontomorph: Mind Meets The World :: Philosophy Science Papers

Ontomorph: Mind Meets The World Chunking of the world as done by the mind depends on how the world is. The world is one object, but not a simple one. Morphological content is just right to allow organisms which move in the world to perform the appropriate dynamical chunking, which from the perspective of the higher cognition may appear to consist of several separate objects. Embracing nonreductionism is desirable because organisms are part of the world. At bottom, there is nothing else other than physical stuff. But it is possible, and indeed it is true, that the physical stuff is very richly structured. One kind of physical stuff are things such as minds. The intricate structure of minds, particularly the complicated topography of their multidimensional space is ultimately responsible for qualitative experiences and consequently for the hard problems of consciousness. As the space of morphological content is itself a part of the physical world, it can begin to throw light on this problem and primarily at the quali tative states — as products of encounter of one form of physical stuff, organisms, with the rest of the physical stuff around them. Some surfaces of the world are moulded and shaped in their encounter other surfaces in the world. But the world has many dimensions; some surfaces are richer than others. The purpose of the shaping is the tacit expectation of further encounters with surfaces in the world. I. Bringing Ontology Of The World And Cognition Together The issues of ontology and cognition are tackled in a separate manner. "As I try to think about the issues in cognition, I try to exclude the issues about how the world is" is an often adopted attitude. This does not mean that investigation of the mind would be extraneous to ontological questions. Quite to the contrary. A respectable contemporary philosopher would normally adopt physicalism as a hypothesis about the mind, thus embracing a materialist ontology. A materialist treats organisms possessing mind as parts of the physical world. The way how the problem is posited then generates a question about the persisting explanatory gap, or about the reductionist hard problem: All in being treated as a part of the world, organisms possessing mind still differ from the World in that they have consciousness consisting of qualitative experiences which are not reducible to the physical World. So one may wish to be a nonreductionist concerning the ontology of mind.

Historical Perspectives in Special Education Essay

Autism Spectrum Disorder There are many different definitions for the term special education. An effective definition for special education is that its specialized instruction that students with disabilities are entitled to receive as articulated in IDEA, (Friend, M). There are many different disabilities that can entitle a student to special education. Students are entitled due to learning disorders, mental retardation, physical disabilities, and also disorders such as autism. In this paper I will discuss doctors, schools, and educators that has had made a difference in the life of a student with autism. Born, February 18, 1906, Hans Asperger was an Austrian pediatrician that published the first definition of Asperger’s Syndrome in 1944. Asperger did a study on four boys and acknowledged a pattern of behavior and abilities that he called â€Å"autistic psychopathy†. The word autistic means self and psychopathy means personality disease. According to Asperger, the pattern included a lack of empathy, little ability to form friendships, one-sided conversations, intense abruptions in a special interest, and clumsy movements. Children with Asperger’s Syndrome had the ability to discuss their favorite subject in great detail and for that reason Asperger often called them â€Å"little professors†. Asperger passed away October 21, 1980, before the identification of this pattern of behavior became widely recognized. Today, technology plays a major role in the life of a student with ASD such as the software Mind Reading, which helps them cope with the disorder ASD and learn different skills daily. Mind Reading is a software that covers the entire spectrum of emotions, and is suitable for the ages of 5 through adult hood. Using the software can help a student explore over 412 emotions, allowing them to hear the emotions by six different people. Mind Reading also provides context, there are 2472 faces, voices, and stories about emotions. Mind Reading is inexpensive for its value. Parents can purchase Mind Reading for $129 for the DVD that contains the emotions library module, games zone, and learning center modules. This DVD can also be run on computers. There is a more expensive software starting at $499 that would be used for classrooms. This device is the DVD with Site License. This package contains 4CDROM disks that are used to install the product directly to the hardware. Mind Reading software can be helpful to a student with ASD in a classroom, by helping them learn their emotions and how to cope with them. This software allowing them to hear so many voices, see so many faces, and hear many different stories gives them the knowledge that they are not the only one’s feeling those different emotions. Aside from the Mind Reading software, there are also different institutions that are helpful to students with ASD and tend to their emotions. There are places such as the New England Center for Children that’s available to students with ASD. NECC has twenty-five years of practical experience. Located in Massachusetts, it is accessible to students with ASD from all over. NECC has a commitment to respectfully provide high quality educational services, and to help each student to reach his or her individual potential and to lead a productive and independent a life as possible. NECC offers several services such as academic, speech and language therapy; development of social and life skills, vocational training, physical education, occupational therapy, family services, outreach services and health care. Independence is strictly emphasized at NECC. There are schools such as Heartspring that serves children with various disabilities as well as schools such as Pacific Autism Center for Education that has residential group homes. Parents may prefer to send their children to a school that serves children with ADS versus an inclusion classroom, because their needs are specifically identified at a school for ASD. Inclusion classrooms are great for social skills but it can cause confusion when it comes to there needs being met. Schools are not the only supporters of ASD; there are also several agencies that serve students with ASD. Bernard Rimland founded the Autism Society of America (ASA) in 1965. ASA is dedicated to increasing public awareness about autism and the day-to-day issues faced by individuals with autism, there families and the professionals they interact with. ASA and its chapters share a common mission of providing information and education as well as research and advocating for programs and services for the autism community. An important service that ASA provides is valuable peer support. Peer support is valuable because it brings together parents and families who are dealing with the same emotions as the others; rather they are joyful or painful. Overall, I believe that if Hans Asperger was still alive today he would be actively involved in the different organizations and agencies providing services for students with ASD. The study that Hans Asperger did has increased in knowledge and if he was still alive today he would have contributed to the study done and correct the assumptions done by society. If Hans Asperger could send a message to me a future professor, it would probably say to be patient with the students with ASD and to take the time to try and understand them. Hans story has inspired me as a future teacher because he watched two young children and noticed something different in them. With what he noticed he did a study and found interesting facts that nobody else ever noticed. That alone has been an inspiration, and a note to me to watch your students and notices there differences it could have a special meaning behind it. Works Cited ASA, The Voice of America. (2004).

Estonia Essay Essay

Estonia joined the European Union as well as NATO in 2004. Estonia has been the first country to allow for internet voting in elections for parliament members (infoplease, n. d. ). Tampering would be thought to be an issue with allow for electronic voting, but the Estonian government has taken the precautions necessary to prevent that from happening. The current president of Estonia is Toomas Hendrik Ilves. President Ilves was elected by an electoral college in 2006. He had previously served in the Estonia Parliament before being elected. The Prime Minister of Estonia, who serves as the head of the government and has just as much if not more power than the president, is Prime Minister Andrus Ansip who has held his position since 2005. The type of government that Estonia has adopted is a Parliamentary Republic. The people of the Estonia vote for the members to represent that parliament, in this case 101 people. Those 101 members of parliament then vote on who the President and Prime Minister of Estonia are. Parliament also gives forth votes to the people on issues that are concerns for the whole country. Estonia remains a so called melting pot for Eastern Europe. The country is made up of 60 percent Estonia’s, with the other 40 percent being from other parts of the former Soviet Republic and a small population from other various parts of the world (Miller, 2009). With this much diversity within the country it is commendable that Estonia has done so well and can be a model of social and political change in just a short period of time after it had gained its independence from the Soviet Union. The political landscape of Estonia remains steady even with the drastic population from other countries. The huge national population disparity can and has lead to violent conflicts in the country. In 2007, the Russians that are in the country went to the capital to celebrate Victory Day, this day being the end of Fascism at the end of WWII. Estonian’s view Victory Day totally different than the Russians that are apart of Estonia. Victory Day to Estonian’s represents the start of Soviet occupancy in their country up until 1990. The Estonian government then moved the statue that the Russians came to, to celebrate, which led to violent clashes with country police for days (Miller, 2009).

Case Studies Abstract

Case Studies Abstract Alfredo Cano Abstract Innovative methods in language teaching may sometimes be slightly difficult for less experienced teachers. Case studies are a relatively new type of task-based activities for business English students. They have been used in language courses for some time now. It seems, however, that their full teaching potential has not been used yet. Teachers seem to be uncertain of how to use cases in class.The paper presents the main pedagogical aspects of using case studies in business English courses. It gives a short description of the structure of typical mini-cases included in recently published course-books of business English. It discusses the basic principles and techniques of using the case study method in class. The main aim of the paper is to present the advantages of the case study method as a new tool of developing learners’ linguistic and non-linguistic competence.Cases offer valuable teaching material that needs to be fully exploit ed. Suggestions given in teacher’s books can be supplemented by various innovative tasks aimed at developing the productive skills of speaking and writing. Cases are motivating for business English learners since they give them the authority to decide what to do to solve a real-life business problem (learners are in the role of managers). Learners can present their point of view, discuss its advantages and suggest a course of action.They have a chance to compete and to demonstrate their analytical and managerial skills. Doing the cases learners use language naturally. In the case study method language is a tool to solving a problem, it is a means of communicating in typical business situations. If teachers learn how to use cases more extensively in the future, they will certainly make the teaching process more effective and studentcentered. 1. Introduction The effectiveness of language teaching depends, among others, on teaching materials.Students and teachers need materials that can improve the language acquisition process and offer more opportunities to develop the productive language skills of speaking and writing. These skills, as opposed to the receptive skills of reading and listening comprehension, are more difficult to acquire and require much more practice and time. In her book on business English teaching Donna (2000) stresses the fact that if students believe that in a language course they do tasks relevant for their future professional communication, they are more motivated to learn.Case studies were first used in law to evidence verdicts given by judges and to teach law students. In the 30s of the 20th century cases were introduced in psychiatry. Case reports were written to document diseases and to consult the cases with other specialists. Today, all medical specialties use case reports for didactic and research purposes. Case studies started to be used in business in 1967 when Strauss and Glazer created their ‘grounded theoryâ€℠¢. In the mid-70s of the 20th century they were introduced in business schools.Harvard Business School has been using this method intensively to teach future managers how to solve real-life problems. Today, the case study method is widely used as a teaching and researching tool in medicine, psychology, anthropology, sociology, economics, management, finance and other sciences where the presentation and analysis of a real problem is of relevance in teaching and researching. The paper presents the case study method as an interesting and motivating teaching material that can be widely used in teaching business English to adult learners. 2.

Analyze Ducati’s Essay

As the case mentioned, Ducati was experiencing a financial crisis before 1996. Just right before Ducati’s bankruptcy, Texas Pacific Group took over the company and appointed Minoli as the leader for the new management team. Despite having high tech motorcycles, Ducati suffered from lack of high quality reputation due to poor management and inefficient production. Under Minoli’s management, he successfully established Ducati’s core logic as a sports bike leading brand, and set company’s core goals as to increase growth as well as maintain profit margin. Minoli began this goal-oriented strategic decision and pointed out a blueprint in order to reshaped Ducati from head to toe. He not only made Ducati to be perceived as a brand to compete in its niche sports segment, but also reeducated the public’s thoughts toward Ducati as a lifestyle and entertainment rather than just motorcycles alone. One key to branding is to maintain customer retention. As mentioned in the case, since 55 percent of Ducati’s customers tend to purchase more than one motorcycles, it is essential for Minoli to establish a high customer loyalty in order to have repurchase intentions. With that aim in mind, Minoli launched levels of investments in customer retention activities to accompany his branding strategy. Implementations include things such as advertising to broaden customer base, creating customer service for quality satisfaction, bike customization for brand niche segmentation, and building Ducati heritage to reconstruct customer loyalty. In addition to branding, Minoli also reorganized production system by outsourcing majority of Ducati’s basic components to maintain the flexibility and efficiency for the production process (76 to 87 bikes produced per worker in 3 year) . Standardizing cylinders and crank cases for different models, acquiring accessories and apparel company also allowed Ducati to yield a higher profit margin (12%) and turnover rate. Furthermore, Minoli also started a new distribution strategy by reorganizing dealerships. To improve the quality and control of the dealerships of Ducati, Minoli began to limit dealerships by carrying only Ducati motorcycles and accessories. Although this act subsequently reduced a number of dealerships in the region, total annual registration still had increased by more than 300% from 2310 to 9750 within 4 years in Italy. In sum, Minoli’s turnaround program has allowed it to create core competencies in brand, product, and R&D technologies by implementing strategies mentioned above. Lowering the cost as well as raising the revenue made Minoli’s goal of long term profit sustaining possible. work cited:Gavetti, Giovanni: Ducati page 11.

Benefits and barriers for implementation of activity based costing Dissertation

Benefits and barriers for implementation of activity based costing systems in selected Asian countries - Dissertation Example Analysis of the three countries is provided. Ultimately, the paper concludes that activity-based costing could be extremely beneficial for Asian businesses. However, activity-based costing is virtually guaranteed to fail if it is imposed top-down or haphazardly. Barriers to implementation include different organisational and social cultures, different accounting norms and regulations, regulatory frameworks, fiscal policies, varying relationships to stakeholders, and other factors. If activity-based costing is to succeed, it must grow organically from the needs and behaviors of the organisations it is applied to. Introduction As Asian countries' financial operations become more closely attuned with and leveled against the West, it is likely that the model of activity-based costing (hereafter known as ABC) will spread to Asian enterprises. This paper analyzes three countries: The Hong Kong SAR, Malaysia and mainland China. These countries are immensely different from the West where act ivity-based costing is more common, with different fiscal policies, regulatory backgrounds, macro-economic statistics and behaviors, regional problems, resources, relations to customers and suppliers, and so forth. Ultimately, activity-based costing could be extremely beneficial for Asian businesses. However, activity-based costing is virtually guaranteed to fail if it is imposed top-down or haphazardly. ... 1.1: Definition Activity-based costing is defined by Rockford Consulting (1999) as â€Å"a method of allocating costs to products and services. It is generally used as a tool for planning and control. It was developed as an approach to address problems associated with traditional cost management systems, that tend to have the inability to accurately determine actual production and service costs, or provide useful information for operating decisions†. Without ABC, managers can make errors in calculation and strategy, particularly in companies with many â€Å"products or services†. The idea is to attribute costs to activities more than products themselves. This requires that processes are mapped and understood sufficiently to be priced or measured. A comprehensive idea of the organisation's process structure, overhead, engineering times, etc. have to be honestly calculated. Ultimately, much like scientific management, inefficiencies are exposed and accounting rectified in areas that were never expected to be problematic. Averkamp (2011) offers an example of activity-based costing that illustrates its benefits. Assuming two products engineered by the same company, â€Å"Product 124† being a â€Å"low volume item which requires certain activities such as special engineering, additional testing, and many machine setups because it is ordered in small quantities† and â€Å"Product 366† â€Å"a high volume product—running continuously—and requir[ing] little attention and no special activities†. Under a traditional costing regime, Product 124 has very low machine hours, thus it would have little overhead â€Å"spread† to it; but this is not an accurate representation of its cost. Similarly, Product 366 would apparently seem to cost a lot because of its

The Veterans Health Affairs Handbook Essay Example | Topics and Well Written Essays - 250 words

The Veterans Health Affairs Handbook - Essay Example As a medical student, I am aware of the growing demand for better health care in our country. This calls for more physicians and nurses as well as coordination of the two groups in offering health care, which is now prone to health care workforce problems. As such, I disregard the draft VHA Nursing Handbook that seeks to eliminate physician-led, team-based care within the VHA system since this will also prevent local facilities from providing such services thus jeopardizing primary health care. Moreover, I differ with medical practitioners who advocate for the independent use of nurses instead of physicians to address the health care workforce shortages since this will put the lives of most patients at a greater risk. Indeed, I think the best way to address these problems is to hire more staff and enhance integration and teamwork among all healthcare providers with a view of offering affordable and effective health care. Nevertheless, the draft VHA Nursing Handbook negates this appro ach as it fosters fragmentation in this sector.  Therefore, I think we should revise the draft VHA Nursing Handbook to reflect a team-based approach that will allow all parties in health care delivery to work together, share decisions and information to enhance healthcare delivery. Indeed, by enhancing integration and teamwork between VHA and physicians and APRNs, this draft would address fundamental challenges in health delivery. Furthermore, the draft should seek to offer longer-term solutions in the healthcare workforce instead of the questionable short-term measures it offers now. With these recommendations, I bet a revision of the draft VHA Nursing Handbook would suit the current healthcare needs.  

Consumer Behavior [Motivation within marketing process] Essay

Consumer Behavior [Motivation within marketing process] - Essay Example This report is divided into three sections, including literature review, reflection, and discussion/analysis. In the first section (literature review), a total of four consumer behaviour theories such as marginal utility theory, consumer choice theory, perceived risk theory, and diffusion of innovations theory are discussed to gain a deep theoretical understanding of various factors that would influence a consumer’s degree of motivation and thereby purchasing behaviour. In the second section (reflection), one of my recent personal consumption activities will be described in order to analyse the motivational factors that led to the specific consumption process. Here, the way the organisation interacted with me to motivate me to consume the product is emphasised. In the third section (discussion/analysis), the major finding of the study is brought together for providing an analysis of my own consumer behaviour in the light of the issues raised in the literature review. Finally, the conclusion part summarises the key findings of the report. In order to critically evaluate the impact of consumer behaviour theories on motivation within the marketing process, it is vital to acquire a better understanding of the concepts of marketing and motivation. The process of marketing is directed at the identification, anticipation, and satisfaction of customer requirements with the ultimate objective of profit maximisation. According to Philip Kotler, â€Å"marketing is that social process by which individuals and groups obtain what they need and want through creating offerings and freely exchanging products and services of value with others† (as cited in Singla, 2011, p.101). The marketing concept is the philosophy that requires companies to focus on the needs of their customers so as to promote decision making and to meet customer satisfaction better than competitors. As Shimasaki (2009, pp. 98-99) describes from the time

Destination Singapore scenario Assignment Example | Topics and Well Written Essays - 2250 words

Destination Singapore scenario - Assignment Example Tourism is a labour intensive industry and expansions in this business will create immense potential for employment in the host country. Though Singapore is small in size, the country has been a hot favourite for tourists and shoppers from across the globe since a long time. The country currently ranks as the third richest nation in the world and though it does not have much in terms of natural resources, due to tourism and other businesses, Singapore has been able to fare quite well in the economic front in the past. However, in order to make the best use of the future prospects, the country has to harness its resources and align its capabilities for improvement and innovation in the travel and tourism industries so that it can sustain the steady economic growth. This paper develops a fictional tourism strategic policy for Singapore on the premise of a situation where the three nearby airports of Bangkok, Kuala Lumpur and Bali are closed down due to natural disasters, which makes th e country the only gateway to other South East Asian countries. It will dwell on various policies that need to be implemented so that the country can optimise its potential as a tourist destination, to cater to the extra demand, over the next five years, in a sustainable manner. Innovations in Singapore Tourism: Strategic Policies and Planning Framework Introduction: Singapore is one of the top ranking economies in Asia Pacific region, with sophisticated infrastructures both in ground and air transport, which rank respectively â€Å"2nd and 14th† as well as a high quality human resources that ranks â€Å"2nd† in the region (Blanke & Chiesa, 2013, p.xxi). In addition, the country ranks as first among all economies for its â€Å"policy environment† that is most supportive with its rules and regulations encouraging travel and tourism industries (p.xxi). Data relating to visiting tourists shows a rising trend with â€Å"11.6 million in 2010 and 13.2 million in 2011 † with revenue earnings of â€Å"S$ 18.9 billion in 2010† and â€Å"$ 22.4 billion† in 2011 (Annual Report of Tourism Statistics, 2012, p.1). Therefore, it transpires that despite the economic down trend across the world, tourism industry in Singapore has been growing in a fast paced manner. The hotel industry in the country also has remained in a strong position over the years with the rates of occupancy up to â€Å"85%† in 2010 and â€Å"86%† in 2011 (Table-34, p.77). Currently, the country has a total of â€Å"154† gazetted hotels with â€Å"40,759† rooms available for letting out (p.83). The land transport system here comprises road and rail services with Express Ways of 161 km, Arterial Roads of 645 km, Collector Roads of 557 km and Local Access Roads of 2,048 km (Singapore Land Transport Statistics as at End of 2011, p.58). In addition, they have Rapid Transit Systems (RTS) with MRT of 146.5 and LRT of 28.8 km, with 97 MRT statio ns and 34 LRT stations, catering to a resident population of 5,184,000 and 13,171,000 visitors (p.58). Air traffic system in the country has accounted for the arrival of â€Å"150,827† aircrafts during the year 2011, carrying 22,778,000 passengers while sea transport has registered the arrival of â€Å"127,998† vessels in 2011 (Year Book of Statistics Singapore, 2012, p.181). This study envisages the development of a new tourism strategic policy and planning framework for Singapore to cater to an extra demand arising from a

Consumer Brand Relationships Literature review Example | Topics and Well Written Essays - 2000 words

Consumer Brand Relationships - Literature review Example In this framework the definitional association is also pertinent. Linking human personality with brand image is not, though, an easy undertaking. The difficulty that psychologists face in determining and assessing personality equally becomes an issue for people who study the art of brand imaging (Bradley, 2010). It is not unusual, therefore, that those who identify brand image by alluding to human personality do not try to identify the latter concept in any more comprehensive way. They just suggest that goods possess behavioural images, or they centre in on some markedly human factor like age, gender or social caste (Batra, Ahuvia and Bagozzi, 2008). Fig. 2 - The determinants of customer-brand relationships (Martensen and Gronholdt, 2010) Brand Relationships Brand relationship, an alleged interpersonal connection in a branding framework,  assumes that brands and customers are able to have a special connection through a shared communication system. Still, some critics have stated th at a brand relationship cannot really be said to reflect an interpersonal association because of the fact that the key components in interpersonal relationships like interdependence and intimacy are lacking. Even though research has in the past revealed that consciousness actually decides how people perform their daily duties, evidence shows that behaviour can actually be in accordance with the pursuit of individual objectives where cognisance is induced (Carroll and Ahuvia, 2006). However, the function of human consciousness is not always obvious a consumer and brand relationship situation. This suggests that the lack of consciousness can actually stop people from value their  relations in a suitable manner. For example, the related members of a... In the present extremely competitive business field, singular images or one-way messages are no longer relevant in capturing and holding consumer interest. A brand’s value is connected to the relationships it creates and the social connections it inspires among consumers who purchase the service or product. The task of managing such extensive relationships that seem to cover every aspect from the production of a product to its consumption is what most marketers are occupied with. If its creators and marketers have taken care to ensure the existence of such relationships, a brand can actually stop being seen as a mere product to become a platform for the shared experiences of its consumers, thus generating more revenue. Defining a brand’s social nature means considering what consumer’s expectations about a certain brand are and how to encourage the consumers to have even loftier expectations in future. Marketers such as eBay and IKEA, for example, are some of thos e that are at the forefront in intentionally inducing a desire for less acquirement of phenomenal experiences with goods or even the products themselves, for more lasting and consequential varieties of fulfilment.

Medical Ethics in the clinical laboratory science Essay

Medical Ethics in the clinical laboratory science - Essay Example The ethical problem will be lying about the capabilities and abilities of john in fulfilling his the new jobs roles. This will dirty the reputation of the manager’s name for a bad recommendation, and it will put john into deep waters for failure to take full charge. The primary stakeholders in the scenario are the laboratory manager and john. The secondary stakeholder is the clinical laboratory that is offering the new job while the tertiary stakeholders are the society and the clinical laboratory science profession (Zhong, 22). Being the manager, the practical alternative is writing a recommendation based on the actual abilities of john. The professional code of ethics addresses the situation and states that the integrity of the profession should be placed above individual and personal interests. As the manager, it is best to mention in the letter, that john is not fit in the position based on his skills level. This enables the manager to work with integrity, respect and competence in accordance with the code of ethics. It is best not to tell john the he was not recommended for the job in order to maintain a peaceful, working environment (Jones, 370). I am a worker working in the night with other technicians in a 300 bed community hospital. One of the co-workers working in the evening shifts is faking the quality control figures. However, after making the realization, I talk to the supervisor about the situation and he tells me to do my work and only mind my business. No one in the department seems to take the quality control matter seriously, yet the errors are avoidable in order to achieve better patient’s results in quality control as well as enhance quality care delivery to the patients. The ethical problem in the scenario is falsification and negligence of the test results yet the supervisors does nothing about it even after being told of the situation in hand. The

American Gridiron Football Essay Example | Topics and Well Written Essays - 3000 words

American Gridiron Football - Essay Example Hence, the total distance between the end zones is 100 yards. (Football Rules and Gameplay) Usually, each team has distinct offensive and defensive units. A team is said to be on offense when it has the ball in its possession, whereas, it is said to be on defense when the ball is with the opposite team. (Football Rules and Gameplay) Before discussing the anatomy of the play from either offensive or defensive point, it would be helpful to detail the different positions that players in each team can play on and the nature of the field. As already stated above, the total length of the football field is 120 yards while in width it is 53.3 yards long. The boundary lines along the length of the field are called sidelines while those along its width are called endlines. Near each end of the field is a goal line. The end zone, mentioned above, extends 10yards beyond this goal line on each side of the field. (American Football) Each team has 11 players on the field at a time, with substitutions allowed during the break between plays. A team can be divided into three units based on the nature of roles performed. These are: the offense, the defense and the special teams. A game begins with a coin toss. The team winning the toss makes one of three choices: 1) Kick off itself, or to receive the kickoff from the other team. 2) Choose which goal to defend. 3) Defer the first choice option to the second game. If the team that wins the toss decides to kick first or to receive the kick, the other team chooses its goal to defend or vice versa. Offense Anatomy of a Play Once the toss has been won and the teams have made their choices, the team that decides to kick first takes up the offensive role as it is in possession of the ball. Typically, all the players of a team round up to communicate or discuss a play i.e. coordinated movements and actions, to be followed; this rounding up of team players is called a huddle. Each half begins with a kickoff. Apart from the start of the half, the play begins at the line of scrimmage with a snap; the line of scrimmage is the position on the field where the play begins and where the offensive and defensive players line up against each other. Snap is the name given to the act of passing the ball between the legs to a teammate, usually the quarterback standing ready somewhere behind the Center. With this snap, performed by the offensive player, playing at the Center position, the game formally begins. Once the game begins, the offense has four attempts to advance the ball 10 yards towards the end zone of the defense team, or in other words, towards its goalpost. These attempts are called downs. When the offense has advanced the ball by the first 10 yards, it gets a first down. After gaining the first down, the team has another set of four downs to gain yet another 10 yards or to score. If however, the offense fails to advance the ball by 10 yards even after 4 downs, the other team gets possession of the ball at the spot of the football, hence beginning with their first down. (American Football) In order to get the downs, the ball can be advanced in one of two ways: By rushing, that means running with the ball, or by a forward pass. While rushing, one ball-carrier can hand the ball to another player, this act is known as a handoff, or throw backwards to another player. This throwing the ball backward is known as a backward pass or a lateral. "A down ends, and the ball

Effects of Alcohol Essay Example for Free

Effects of Alcohol Essay Alcohol can have some good benefits and then some bad ones, for example when you drink you can encounter yourself having a good time laughing and joking around with your friends, or you can find yourself angry wanting to argue and start fights with everybody. If you’re a â€Å"happy drunk† you probably don’t have bad alcoholism in your family, and you can control your drinking with the attitudes it may drag along. While on the other hand if you’re an â€Å"angry drunk† you may not be able to control what you do when you drink such as the amount of alcohol you consume or the attitudes that may come along with drinking. Alcoholic content in most alcoholic drinks is measured in proof, which is about half of the actual content of alcohol in the drink. An example is a 90 proof whiskey actually only contains 45 percent alcohol. Beer is one of the beverages containing the lowest proof. They range from 2 to 6 percent. Wines have anywhere from 14 percent or less. Fortified wines which have other alcoholic beverages included will be in a higher range. While drinking each of these different alcoholic beverages, each one of them has different serving sizes like with whiskey 1 serving is about half a shot glass, one serving of beer is a 12oz can of beer and the smaller amount of whiskey will get you drunk way faster than beer. When drinking you need to keep track of what you are drinking and at how fast of a pace because if you drink fast you will reach your state of being drunk a lot faster and the buzz be a lot more intense than you may want. But if you are drinking at a slow pace and not drinking those hard alcohol drinks your buzz will come a lot slower and easier to contain. In some of the first steps of alcoholism the image of drinking is no longer to socialize and have a good time it becomes a necessity to cope with life to escape from stress, inhibitions and anxiety. Early in the disease of alcoholism the person with the drinking problem starts to depend on the mood changing aspects of alcohol. Another aspect of the first stage of alcoholism is that a gradual increase in tolerance develops, meaning that increasing amounts of alcohol are needed in order to feel a high or a buzz. When your tolerance goes up you need to consume more alcohol, so might change to stronger drinks which may have different effects on yourself and change your personality severely making people that you once held close in your life to drift away and leave your all alone with only yourself and your drink. The person with the drinking problem starts to avoid family and friends and experiences a loss of interest in activities that used to be fun or important causing them to lose their job and other fun activities forcing them to fall into a deep depression then they may not have anywhere to turn besides the bottle of alcohol so they can deal with life the only way they know how to now. Soon an alcoholic will need to have a drink as soon as possible like when they just wake up in the morning so they don’t have to deal with the true reality of their life, calming there nerves or to lessen the hangover so soon being drunk all day everyday becomes a regular routine in daily life. Coming alone with being drunk that much has some very bad effects like, an increase in failed promises and resolutions to ones self and to others, Frequent violent or destructive behavior, The start of physical deterioration and all this will lead to major problems with the law such as DUIs and jail time which could also bring along thoughts of suicide. Now at this point of alcoholism it is more than likely the person will not be able to hold a full time job like they could have in the earlier stage of becoming an alcoholic because drinking starts earlier in the day and usually continues all day long. Then once the person has come all this way the body is not going to be able to deal with this frequent drinking because alcoholism causes a number of medical conditions and cancers. The noncancerous medical problems with this horrible addiction/disease can include, Harm to the fetus while the mother is pregnant, cardiovascular problems such as high blood pressure, heart failure, and strokes, impaired learning ability, kidney and liver failure, diabetes, alcohol poisoning and sexual problems such as erectile dysfunction and impotence in men are just some of the few side effects with alcoholism. Some of the cancerous problems that may come along are Stomach, Liver, Esophagus, Kidney and Colon cancer. When or if an alcoholic comes to reality and wants to quit drinking if forced by family and friends or medical conditions and can be too late for them because if a person has been addicted to alcohol for a long period of time their body is more than likely dependent on the daily consumption of alcohol and cannot function without. They could have been diagnosed with a cancerous symptom from drinking and need to quit or they will die, but on the other hand they can die from the sudden stop of drinking. Alcoholism is one of the most dangerous addictions’/ diseases’ out there because there is no cure and causes more deaths than a good deal of other drugs and addictive’s. Many studies have concluded that alcoholism is as addictive as or more addictive than heroin or cocaine, therefore before getting stuck going down the dead end road of alcoholism think twice.

Development of an Equation Essay Example for Free

Development of an Equation Essay Purpose: Investigate a chemical reaction using lab procedures and observations. Then, find a pattern of reactivity and explain the findings using a chemical equation and particle diagram. Procedure: Refer to: Department of Chemistry, The Ohio State University. Development of an Equation. General Chemistry 1210 Laboratory Manual. Vol. 2013-2014. Plymouth: Hayden-McNeil. 32-35. Data/Results: Part A: In the potassium iodide solution, I think there were potassium atoms as well as iodine atoms. In the lead nitrate solution, I think there were lead and nitrate ions. The potassium atoms and the lead atoms can be classified as cations, since they are metals. The iodine atoms and the nitrate ion can be classified as anions since they are nonmetals. Upon mixing, the solution turned into a cloudy yellow color. Evidence that a chemical reaction occurred was that the two solutions created a new color because the two solutions were originally colorless. There was no gas formed. Part B: (Testing the Anions) Iodide reaction with hydrogen peroxide observations- The precipitate at the bottom turned into a red solid and the liquid solution was a dirty yellow color. Nitrate reaction with hydrogen peroxide observations- A colorless precipitate formed at the bottom and looked like a bubble. It was a relatively large bubble. The liquid solution was colorless and cloudy/fizzy. Since the reaction resulted in some fizzing and bubbles, this is indication that a gas was formed. (Testing the Cations) Potassium reaction with thioacetamide observations – No reaction occurred. Lead reaction with thioacetamide observations A violet-black precipitate formed at the bottom of the test tube and the liquid solution was a cloudy grey color. It was about the same size precipitate as the nitrate reaction with hydrogen peroxide. Strong smell from the thioacetamide. Part C: Identification of ions in the precipitate that forms when lead nitrate solution is added to potassium iodide solution. (Testing for Anions) Reaction with hydrogen peroxide observations- A dark red precipitate formed at the bottom of the test tube and the liquid solution was colorless. There was not a large amount of precipitate formed and it sort of smeared along the inside of the test tube. Inferences: What anions are in the precipitate? -iodine (I-) When compared with results from part B to test anions, similar results were found. A dark red precipitate was formed in both. (Testing for cations) Reaction with hydrogen sulfide observations- A small, violet-black precipitate formed at the bottom of the test tube and the liquid solution was grey and cloudy. Inferences: What cations are in the precipitate? – lead (Pb2+) When compared with results from part B to test cations, similar results were found, A violet-black precipitate was formed in both tests. Exchange reaction- Positive potassium started off with negative iodine, and positive lead started off with negative nitrate. Potassium switched to combine with nitrate and lead switched to combine with iodine. Part D: Testing of Precipitate| Observations on Initial Precipitate Formed (relative amount, etc.)| Lead Nitrate: Potassium Iodide Ratio| Tube 1| Powdery, yellow precipitate formed at the bottom. Not very much precipitate. Little to no streaking. Clear liquid solution above precipitate. | 3:1| Tube 2| Powdery, yellow precipitate formed at the bottom. Equal to tube 1. Little to no streaking. Clear liquid solution above precipitate.| 2:1| Tube 3| Powdery, yellow precipitate formed at the bottom. A little more precipitate than tube 1 and 2. Little to no streaking. Clear liquid solution above precipitate.| 1:1| Tube 4| Powdery, yellow precipitate formed at the bottom. Much more than tube 3. Noticeable streaking of precipitate along sides of test tube. Clear liquid solution above precipitate.| 1:2| Tube 5| Powdery, yellow precipitate formed at the bottom. Most precipitate formed out of all test tubes. A lot of streaking of the precipitate along sides of the test tube. Clear liquid solution above precipitate. | 1:3| Testing of Supernatant| Observations| Inferences: Which ions were in the supernatant? List cations and anions.| Tube 1| The solution was clear with lead nitrate, but turned a yellow cloudy color with the potassium iodide. | Pb2+ (lead)-cationsNO3- (nitrate)-anions| Tube 2| The solution was clear with lead nitrate, but turned a yellow cloudy color with the potassium iodide.| Pb2+ (lead)-cationsNO3- (nitrate)-anions| Tube 3| The solution was clear with lead nitrate, but turned a yellow cloudy color with the potassium iodide.| Pb2+ (lead)-cationsNO3- (nitrate)-anions| Tube 4| The solution was clear with both the lead nitrate and the potassium iodide.| Pb2+ (lead)-cationsNO3- (nitrate)-anions| Tube 5| The solution was a little yellow with the lead nitrate, and a little less yellow with the potassium iodide.| K+ (potassium)I- (iodine)| Discussion/Conclusion: In part A, the first step was to obtain 5 drops of potassium iodine and 5 drops of lead nitrate and put them into a test tube and record observations. Then, to test the anions in part B, 5 drops of potassium iodine, 5 drops of nitric, 10 drops of dichloroethane, and 5 drops hydrogen peroxide to a new test tube. Then to a separate test tube, 5 drops of potassium nitrate, 5 drops of nitric acid, 10 drops of dichloroethane, and 5 hydrogen peroxide to a new test tube. Both should be stoppered and shook to produce two distinct layers. To test the cations, 2 test tubes would each get 20 drops of thioacetamide and 2 drops of nitric acid. One would get 5 drops of lead nitrate and the other 5 drops of potassium nitrite. Both test tubes were heated for 5 minutes and observations were recorded. In part C, the sample was used from part A and the test tube was centrifuged, then the clear aqueous layer was removed and discarded and the precipitate was washed with distilled w ater. This process was repeated once more. To test the anions, 5 drops of nitric acid, 10 drops of dichloroethane, and 5 drops of hydrogen peroxide were added to the solid precipitate and the test tube was stoppered and shook. These results were compared to the results from part B. To test for cations, the less colored aqueous layer was transferred to a clean test tube and the leftover layer was discarded. The solution was heated in a water bath until clear. 20 drops of thioacetamide were added, stirred then heated in a water bath and compared to the results from part B. In part D, to determine the ratio of  ions in the precipitate, 5 test tubes were labelled 1-5 and were filled according to table 3.1 on page 34 of the lab manual. The same medicine dropper was used for all drops and the test tubes were stoppered and shook, then centrifuged. The relative amounts and appearance of each precipitate were recorded. To test for potassium of iodide ions in the supernatant, 5 drops of lead nitrate were added to 5 separate test tubes with along with 5 drops from the appropriate test tube solution. The same was done to test for lead or nitrate ions, but potassium iodide was added instead. The perfect ratio for thi s lab was 2 potassium iodides for every lead nitrate. This ratio was found from balancing the equation and from comparing the results from part C to part B to match the observations of the precipitates. The ratio is the molar mass ratio of the balanced equation. The balanced equation was: 2KI(aq)+Pb(NO3)2(aq) 2KNO3(aq)+PbI2(s) and the formula of the precipitate was PbI2(s) based on the observations. In part B, the test for anions resulted in a dark red precipitate which was the iodide solution with hydrogen peroxide. In part C, the same results were found when lead nitrate and potassium iodide were added to hydrogen peroxide, therefore; the anions found were iodide ions because it has a negative 1 charge. In part B to test cations, the precipitate was a violet-black color for the lead solution reaction with thioacetamide. In part C, the same results were found when lead nitrate and potassium iodide were added to hydrogen sulfide. The cations found were lead ions since they have a positive 2 charge. Some inherent errors could have been while extracting the clear aqueous solution, some of the precipitate could have been extracted with the solution and transferred into another test tube. Upon heating, not all of the precipitate dissolved. Some of the drops with the micropipet varied also. The medicine dropper was more precise with the drops. Through this lab, a chemical reaction was used to find the pattern of reactivity which was an exchange reaction. This is known by finding the chemical equation and properly balancing it which is seen above. This lead to the ability to create a particle diagram and the findings of a perfect ratio of lead nitrate to potassium iodide.
