Risk Assessment
Hazard Identification Risk assessment begins with hazard identification. Malathion is a wide spectrum, non-systemic organophosphate insecticide commonly used to control ectoparasites, household insects, sucking and chewing insects in agriculture, and mosquito populations (Pmep.cce.cornell.edu 2012). It is also sold over the counter as a medicine used to kill lice and their eggs. Toxicity in animals depends on product purity and the method it is administered.

Dose-Response Assessment Dose responses in humans and animals differ from species to species and according to dose concentration. Malathion exposure occurs through ingestion, inhalation, and absorption. Human exposure usually results in nausea, headache, and tightness in the chest. Although Malathion is classified as a slightly toxic, lethal doses have been recorded for humans. The lowest lethal dose of Malathion recorded is three times higher for men than women (Pmep.cce.cornell.edu 2012). Alergic reaction to Malathion causes severe dizziness and trouble breathing. Lab tests indicate that rats do not normally have adverse reproductive and development effects from Malathion exposure at low doses and prolonged exposure. High doses can cause teratogenic effects when fed to rats through a stomach tube. Malathion can, however, pass through the placenta of pregnant goats and cause birth defects and increased newborn mortality rates. Chronic toxicity may cause mutagenic risks to humans. Lab test results showed that white blood cells and lymph cells from human cell cultures mutate when exposed to high levels of Malathion. Lab rats fed Malathion showed signs of negative effects on the adrenal glands and the liver, though these were not cancerous effects. According to these studies, there is not enough evidence to suggest that Malathion causes cancer in mammals. Other research from the University of Florida points to the opposite theory. According to studies from the university Malathion causes kidney damage and can ‘knock-off genes from chromosomes’ (Chem-tox.com 2012). After a Malathion spraying in Pakastan at least 5 people died and around 2,800 people were poisoned by the insecticide. Malathion is highly toxic to aquatic invertebrates, amphibians, and honey bees and moderately toxic to birds. Fish and aquatic invertebrates experience a wide range of Malathion toxicity at levels ranging from 1 ppm to 1 ppb. Organ and genetic damage in lizards, turtles, and tadpoles has been linked to Malathion exposure in research studies conducted by the University of Florida (Chem-tox.com 2012). Another ecological problem that could directly affect our food source is the inhibition of chemo-receptors in shrimp when exposed to the pesticide. Shrimp use chemo-receptors to find food, but exposure to Malathion is recorded to reduce chemo-reception by 50%.

Exposure Assessment Humans are generally exposed to Malathion when it is used to control mosquito populations or other household insect populations. Large area sprayings and Malathion bombs are responsible for most severe human contact with the toxin. Environmental and ecological problems occur when Malathion is washed into waterways, rivers, lakes, and bays. The sensitivity of many aquatic organisms to this pesticide may create breaks in the food chain and loss of certain species over time in certain regions. Any genetic change in a species has the potential to be deadly. Once water is polluted with toxic chemicals it proves difficult to make safe for consumption and for the ecosystems surviving in it.

Risk Characterization Although Malathion can be harmful to many species in small doses, humans do not tend to suffer from minute amounts of the pesticide. Using Malathion to control mosquito populations on a golf course could be acceptable if the toxin does not enter ponds, streams, or lakes that contain aquatic life. The effects of Malathion on bird physiology must be taken into account when considering concentrations of Malathion to be used as birds are likely to visit any water available on the golf course. The risk of using Malathion to control mosquito populations on the golf course is great if there is an ecosystem in place that may be polluted by direct exposure from spraying or run-off.

...Management Fall 2009 Non-financial risk assessment in mergers, acquisitions and investments Identifying sources of business risk in the ICT industry Bachelors thesis Erik Allenstr¨m, 1984-11-26 o Fredrik Njurell, 1984-01-30 ¨ Tutor: Osten Ohlsson January 14, 2010 Abstract The number of company mergers and acquisition activities has increased dramatically the last two decades. The reasons for conducting these activities are many and the uncertainties of their results are high. To reduce the uncertainties when making an investment, merger or acquisition it is vital to do a thorough assessment of the risks involved with the activity. This thesis focuses on a specific part of this risk assessment, namely the non-financial risks. Mergers and acquisitions are done in almost all industries around the world and the reasons for and benefits of these activities can vary between industries. We have chosen to investigate the risk assessment of non-financial risks in the Information and Communication Technology (ICT) industry. The thesis aims at investigating what business characteristics, for companies in the ICT industry, that give rise to non-financial risks that must be assessed when doing investments, mergers or acquisitions. Further on we present a risk pattern that points out what business characteristics that are the most important when conducting a risk assessment of non-financial risks on companies in the ICT industry. From a literature study we find evidence that ten different...

...Running head: PURCHASING A HOUSE RISK PAPER Purchasing a House Risk Paper Keller Graduate School of Management Project Risk Management PROJ 595 Dr. Susan Orr August 04, 2013 Purchasing a House Risk Paper INTRODUCTION The many advantages to owning a home have been well publicized. However, the above satistics make it clear that owning a home is not without risk. To form a complete picture, you, the prospective buyer, need to consider the potential risks and disadvantages of home ownership as well. Understanding these disadvantages beforehand will give you a better chance of minimizing their impact and avoiding the fate suffered by these homeowners. RISKS IDENTIFICATION There are many risks in buying a new house such as: • The opportunity cost of investing in an alternative investment is very high because the entire cash and future income stream is tied up into one asset a home, which may or may not appreciate. • The house is an undiversified investment, so if the market tanks as it has, game over. • Knowing that we do not own our home, the bank does. • A lot of cost connected to home ownership, such as repairs and insurance and fees and potential hazards I have not considered. • If I lose my job, game over, this will put a lot of stress on me. • There is a chance that your new home will lose value. Luckily, in general, the longer you own your home, the less likely a loss becomes. Loss of value is typically a short-term problem, possibly due to the local...

Risk Management Overview

...Risk Management Overview February 21, 2011 FIN/415 Risk Management Overview Paper Risk management is a systematic process of managing the exposure of the organization to a variety of risks. This process has become increasingly important for the success of any organization in current competitive markets. The successful identification of threats and opportunities is crucial in risk management as it allows to create the processes and procedures allowing the company to maximize opportunities and minimize threats. Many organizations treat risk management seriously and create separate department responsible solely for risk management. Royal Caribbean Cruise Line incorporated risk management department into its structure. This step allowed this organization to improve the risk assessment procedures and introduce the necessary processes to minimize the impact of threats. The organizational risk relates to the organizational governance, operations, and information systems. The organizational risk management “provides assurance for reliable and accurate financial and operational information and reporting, effectiveness and efficiency of operations, and safeguarding of assets, as well as compliance with regulations, contracts, and the organization’s code of ethics” (Aghili, 2010, p. 23).

Risk Assessment

...large emphasis on financial risk assessments. The risk assessment process is needed to identify risks that need to be treated within an organization, as well as to provide strategies and methods that are most appropriate to treat these risks. Because many organizations are poorly aligned between their risk exposure and their risk appetite, it is important to engage in the risk assessment procedures. These procedures can help an organization prevent risk exposure and determine if their current operations will result in an increase or decrease of market value and owners’ wealth. As a result of the economic crisis, and the recent increase in corporate failures, organizations can now learn from the mistakes of others. This paper will discuss the mistakes that lead WorldCom, a telecom company that was once the fourth-ranked in Fortune 500, to bankruptcy in 2002, in an effort to demonstrate the importance of successful risk assessment and alignment implementation. Keywords: corporate failure, risk analysis, risk assessment, risk management, WorldCom Over the past years, and as a result of high profile firm failures, the economic crisis, and increased regulatory pressure, many organizations have placed a large emphasis on financial risk assessments. Risk assessment is the process where risk managers analyze the risks of an organization and identify risks that need to be treated (Tarantino & Cernauskas, 2011, p.47). In addition, a risk assessment provides strategies and...

Fraud Triangle

...AC572 You Decide Jan. 24, 2011 When evaluating this case using the three elements of the fraud triangle I have concluded that the potential pressures for Chris to commit fraud are greater than for others. The pressure is from Chris himself because he wants what others have or what he doesn’t have. This is due to the fact that Chris is young and impressionable may feel as though he doesn’t make enough money to obtain the material possession he desires or see others with. He may also be of the mindset that “he wants it now” it being the latest technology. This younger generation seems to feel entitlement instead of working and earn it. This may be due to their upbringing. Although my generation had things we worked for them and with our parents/families help we were able to obtain those things we wanted. We live in a technology savvy society so if you don’t have the last gadget then you may be looked upon as not having the means to acquire these things or not technologically savvy enough to want or have these items. Having the latest gadgets is a societal status symbol, the more you have…. the more you have meaning money. Chris may have friends that have the latest and greatest technology and he maybe envious of them and desire to acquire those things as well but not on his salary in his mind. So he must find a way to get either more money or a way to acquire the latest and the greatest in technology. The potential opportunities for Chris to commit fraud are great...

...RISK PM595 Initial information used in phase 1 of the assessment process is based on project documents and the request for tender itself. Information for Phase 2 is derived from individual tenderer’s response. In phase 1, an appropriate system or element structure for examining the tender is developed and semi-quantitative approach is used to assess the likelihood of risks arising in each element and their consequences and then derive a baseline priority for each element and the project. In phase 2, the evaluation is modified according to the detailed approach each tenderer intends to adopt, and that tenderer’s capabilities. According to the text book some of the objectives of the risk assessment in tender evaluation are to provide an initial indication of where the major risks might arise in the project, prior to receipt or detailed examination of tender responses, based on a set of credible assumptions about how the project might be conducted. It also develops a risk baseline against which individual tender responses can be compared. It assist the project team to focus on potential risk areas, it provides a risk profile for each tender offer submitted and provides a documented audit trail. In Phase 1 a baseline is established against which tenders can be assessed before bids are received. In Phase 2 each submitted tender offer is compared with the baseline to develop a comparative risk assessment for each one. In phase 1 the structured and documented risk assessments...

I have not been in a role of a manager yet have supervised a number of interns and I have never been threatened by or with any responsibilities pushed upon me. In fact, I almost always took same on with confidence and a sense of dedication. I do agree with the assessment that at times I may not give myself full credit where I completely deserve it; I have attributed this more to humility than to insecurity. Although I am not hard on myself for mistakes and misjudgments I do, however, tend to dwell on things far longer than necessary. For example, if during a presentation I stumbled in answering a question I would live with the embarrassment of same for weeks and in fact avoid the person who posed the question. The measure of conventionality perhaps may be a more in line with my thinking; however, I completely disagree with the conformity assessment. I do assess risk probably more staunchly than others yet I do not restrict myself in doing tasks “the way they have always been done” if that way does not seem to be working. I do take...

Risk is associated with our health, safety, security, well being, employment, education, daily activities, using resources and equipment and community participation. Some adults such as those who are disabled or who are older are usually discouraged from taking risks with their budgeting, planning, employment and their daily living skills usually because people fear for their limitations or that they might hurt themselves or others. Everyone has the right to take risks and make decisions about their own lives, a balance should be found between service users participation in everyday activities and the carers duty of care. Social care and health policies are encouraging residents to increase their independence by being involved in the wider society such as leisure and work. It should be noted that it is impossible to eliminate risk completely, however minimising and being prepared for risk by preventative action.

Enterprise Risk Management

...Enterprise Risk Management The Non-Linear Pro salesman told the manager of Quick Takes Video that the editing system leased would allow the employees to edit material twice as fast after only a day and a half of set up and training. After all employees received the one-day training course, completed the video tutorial, and read the manual, problems with the equipment stopped production of a Quick Takes Video project. During an attempt to insert a CD, an employee cut her finger on a sharp edge of the poorly designed equipment. Two different types of torts arose in the Product Liability Video. One type, an intentional tort occurred as a result of the implied warrantee when the salesman described the benefits of the editing system. The employee’s cut finger could result in an unintentional tort because the manufacturer has the requirement of selling a safe product but did not intend to harm the employee. The main tort violation from the video involves the implied warrantee given by the Non-Linear Pro salesman. The manager of Quick Takes Video perceived the quote taken from the video Cheeseman (2010), “Any of your editors, if they’re computer savvy, they’re going to pick this up in a day, day and a half tops” (video, 02:79), as an expressed warrantee. This perception persuaded the manager to lease the equipment. Team A used enterprise risk management (ERM) to analyze the business risk associated with the violation (Harb, 2008).
