...Journal of Business & Economics Research – July 2005 Volume 3, Number 7 Operations Research And Operations Management: From Selective Optimization To System Optimization Jack A. Fuller, (E-mail: jfuller@wvu.edu), West Virginia University C. Lee Martinec, West Virginia University ABSTRACT The focus of this research paper is to discuss the development of Operations Management (OM) and Operations Research (OR) with respect to their use within the organization’s decision-making structure. In addition, the difference in the tools and techniques of the two fields is addressed. The question is raised as to how distinct the two academic fields have become in light of the application of their models to the service industry. Suggestions are made regarding the possibility of incorporating OM/OR models and their output into the decision making structure of the organization towards the goal of “system optimization”. ORIGINS OF OPERATIONS MANAGEMENT AND OPERATIONS RESEARCH A comparison of the origins of operations management and operations research reveals that both are an innovation of the 20th century. The origin of operations research was in England, circa 1937, and has its roots in scientific management, with its first significant applications to military operations in both World War I and World War II. Operations management had its origins in the early factory system, and was more associated with physical production in a factory environment and it too was strongly influenced...

...Down syndrome Development Psychology Down syndrome Love a four letter word that many will take and throw around as though the word is a ball to be toyed with. One seeks to have someone say “I love you” no matter what their ability is as being mentally challenged or not. A parent does not love his or her child any less if he or she suffers an illness such as that of Down syndrome (DS). In order to completely understand how the love of a mother and father can be given to a child with such a disability, the individual needs to gain an understanding of what Down syndrome is. The reader of this paper will learn how Down syndrome got the name, what Down syndrome is, the case for this disorder, the facts that are known of Down syndrome. The methods used to test and find DS before the birth of a child. Statistical facts, the medical conditions which are present, how parents and teachers work with those born with DS. How the eating habits, sexuality habits of males and females with Down syndrome are viewed. The length of the life expectancy for someone who is challenged with DS compared to someone that is not mentally challenged. The last thing that I will cover within this paper is that of foundations that have been created to conduct research and treatment for those with Down syndrome and to answer the question that many may have as to there being a cure for Down syndrome. Down syndrome a term that many are familiar with in the United States; the scientific name...

...longer life without problems. Introduction: Like most people, you already know that smoking is bad for your health. But do you really understand just how dangerous smoking really is and how it can be also deadly for non smokers too? Do you know that the World Health Organization (WHO) estimates that each year smoking causes about 6 million deaths which is about 10% of all deaths and 0.6 million of these occurring in non smokers too due to second hand smoke? Do you know that smoking is considered as the greatest cause of preventable death globally? Since stopping smoking can be an extremely difficult process, understanding exactly how smoking harms your body and people around you can help keep you motivated to end that habit. So in our research we are going to talk about smoking health problems and second hand smoke. Literature review: Male and female smokers lose an average of 13.2 and 14.5 years of life, respectively. [1] About one half of long term male smokers will die of illness due to smoking. A person's increased risk of contracting disease is directly proportional to the length of time that a person continues to smoke as well as the amount smoked. However, if someone stops smoking, then these chances gradually decrease as the damage to their bodies repaired. A year after quitting, the...

...To Legalize or Not to Legalize Medical Marijuana Elizabeth Connell ENG/102 Research Writing To Legalize or Not to Legalize Medical Marijuana Even though marijuana is a drug, legalized marijuana for medicinal use will help patients through various medical issues. Marijuana has been proven to ease the side effects of chemotherapy, helps patients with severe migraine, and glaucoma patients. Many people are on the fence over the legalization of medical marijuana. There are several reasons to legalize marijuana for medical use, let me tell you about one of the reasons. Six-year-old Charlotte is a little girl who suffered from an untreatable form of epilepsy. By the time she was two years old, her parents had tried all medications to cure her some of which almost killed her. She suffered nearly fifty seizures a night. Her parents managed to get her a medical marijuana card in Colorado. Her parents reported her seizures stopped after her first dose of cannabis oil. Charlotte came out of her catatonic state and met her parents for the first time. CNN featured Charlotte and documented her story. Some parents have turned to medical marijuana to treat their children of the incapacitating epilepsy. Doctors are attributing the drug with reducing seizure activity and bringing alleviation to epileptics. According to an article written by K. Pickert (2014), an innovative clinical trial is about to commence. This clinical trial may finally afford some science to support their assertions...

...facilities young people are taught to be functioning attributes to society, and the main way to do this is by obtaining employment. Often these youth are plagued by physical and mental disabilities that will give them a harder road than someone applying for the same position. The U.S. Census Bureau says that about 49.7 million Americans have a disability. Those with a physical disability were 9.4 percent, mental disability was 5.6 percent for people age 16 and older, and 6.9 percent had an employment disability (census.gov). When youth leave facilities were they have been groomed and ultimately institutionalized, they are stuck without skills that will help them obtain employment and be able to compete in today’s society. The research in this paper will explore the laws that protect those with disabilities and how they may be improved to provide them with equal employment opportunities. These youth put so much of their self-worth into having a job but are often discriminated against. Getting up and being involved in a working society puts forth an image of belonging as so many times in their past they have been shunned aside and made to feel inferior by those most important to them. Disability discrimination occurs when an employer or other entity covered by the Americans with Disabilities Act, as amended, or the Rehabilitation Act, as amended, treats a qualified individual with a disability who is an employee or applicant unfavorably because she has a disability (eeoc.gov)...

...ABSTRACT Nigeria is an oil rich country, as a matter of fact the sixth largest oil producer world over, the 26th largest economy in the world and Africa’s largest economy. Paradoxically, this same resource-rich nation ranks among the five “extremely poor” nations of the world, ranking 153rd with a Human Capital Development Index of 0.471 according to UNDP in 2013. Of course this does not portend economic development. What is however, not surprising is Transparency Internationals’ Corruption Perception Index which ranks Nigeria as one of the most corrupt countries in the world, coming 144th out of 177 surveyed countries. This paper therefore seeks to examine the accountability of public officers in Nigeria and their effects and bearing on the economic development of the nation. It also looks at the factors militating against public sector accountability and the ways of achieving accountability in the public sector. The study uses historical data and a descriptive approach of study; it was found that Public sector accountability is essential to economic development in Nigeria. And the nation seems to exist at two extremes, abundant resources at one extreme, and poverty at the other extreme due to lack of accountability in public sector. Amongst others, it is recommended that the legislature should champion the accountability process, the Nigerian society should be re-orientated on value process, and whistle blowers should be protected to achieve accountability and economic development...

...ISSUES AND CHALLENGES IN CYBER ETHICS INTRODUCTION According to Barquin (1992), cyber ethic guidelines consist of Ten Commandments which are: (1) Thou shall not use a computer to harm others, (2) Thou shall not interfere with others computer work (3) Thou shall not snoop around in others computers files, (4) Thou shall not use computer to steal, (5) Thou shall not to bare fall witness, (6) Thou shall not copy or use proprietary software you have not paid for, (7) Thou shall not use others computers resources without authorization or proper compensation, (8) Thou shall not appropriate other people’s intellectual property, (9) Thou shall think about the social consequences of the program you are writing or the system you are designing (10) Thou shall use a computer in ways that ensure consideration and respect for your fellow humans. These commandments or rules need to be obeyed by everyone who utilizes the cyber space facility in order to maintain the tranquility of cyber world. However, not everyone concern about these rules as we seen nowadays. In order to prevent plague from spreading and become worse in future, we have to identified the root cause of the problem and define how to solve it. The first commandment explained that it is not ethical to harm another user by using computer and it is not limited to physical injuries but also harming or damaging other user data or files. It is unethical to create a programmed that deliberately allows someone to steal, copy...

...Research Proposal: A CRITICAL ANALYSIS ON THE IMPLICATIONS AND EFFECTS OF CORRUPTION IN THE SOUTH AFRICAN ECONOMY AND HOW IT CAN BE MANAGED About the writer: Tyson Thamsanqa Sibanda Rosebank College South Africa: Bachelor of Business Administration 3 (2015) Contact details; Tyson.msimanga@gmail.com 0027786500000 / 0027815993434 BACKGROUND AND ORIGIN Corruption in South Africa has been so widespread that, unless it is decisively tackled in this presidential term, there is a real danger that it will become embedded as a ‘normal’ aspect of life in our country. Once it becomes part of the ‘culture’ of our society, it will be almost unmanageable to uproot. Corruption is generally defined as the abuse of public office for private gain. It usually comes in two forms. Firstly, the alleged ‘big-time’ corruption which take place when public officials bend the rules to channel patronage to relatives, friends and associates, or accept bribes; as well when private agents bribe public officials to give them exclusive advantages or privileges. Secondly, there is the quiet corruption, which occurs when public servants purposefully neglect their duties to provide public services or goods. Quiet corruption may not involve an exchange of money, but involves providers of public services such as teachers, nurses or other government officials, twisting the rules for their own private welfares. This includes, for example, public servants, such as a minister or nurses not turning up for work when...

...1007/s10734-009-9216-y Groupwork as a form of assessment: common problems and recommended solutions W. Martin Davies Published online: 20 March 2009 Ó Springer Science+Business Media B.V. 2009 Abstract This paper reviews some of the literature on the use of groupwork as a form of assessment in tertiary institutions. It outlines the considerable advantages of groupwork but also its systemic associated problems. In discussing the problems, the paper considers issues such as ‘‘free riding’’ and the ‘‘sucker effect’’, issues associated with ethnic mix in groups, and the social dilemma problem—in which students face conflicting demands between altruism and self-interest. The paper then outlines several models of effective groupwork and makes suggestions for implementing groupwork tasks. The paper also looks at the key assessment tasks which are commonly employed—namely, additive, conjunctive, disjunctive and discretionary tasks—and assesses which are most suited to groupwork. The paper considers the related issues of task complexity, recognition for effort, and strategies for minimising issues concerning group size. The paper also briefly considers strategies for implementing incentives for groupwork members, and outlines the issue of penalties for unproductive group members. The paper concludes by providing recommendations for how to maximise the advantages of groupwork while trying to minimise the disadvantages.

...UNRESOLVED GRIEF AND CONTINUING BONDS: AN ATTACHMENT PERSPECTIVE Much of the contemporary bereavement literature on the continuing bond to the deceased (CB) has emphasized its adaptiveness and given limited attention to when it may be maladaptive. The attachment literature on disorganized– unresolved attachment classification in relation to loss, or ‘‘unresolved loss,’’ is informative in identifying CB expressions that are indicative of failure to integrate the death of a loved one. In this article, an important linkage is identified between a prominent indicator of unresolved loss that involves a lapse in the monitoring of reasoning implying disbelief that the person is dead and the clinical writings of J. Bowlby (1980) and V. D. Volkan (1981) on maladaptive variants of CB expression. The aim is to highlight the value of the attachment literature on unresolved loss in clarifying the conditions under which CB is likely to be maladaptive. There is increasing agreement among bereavement theorists and practitioners that an ongoing attachment to the deceased can be an integral part of successful adaptation to bereavement (Klass, Silverman, & Nickman, 1996). This position, commonly known as the ‘‘continuing bonds’’ perspective, is counter to that presented by Freud (1917=1957) in his classic work ‘‘Mourning and Melancholia,’’ in which he proposed that successful adaptation to loss required the bereaved to detach his or her psychic investment in the deceased...
