Marginal analysis Essay Example | Topics and Well Written Essays - 500 words

Marginal analysis - Essay Example If the marginal revenue is known, then the total revenue can be worked out for a specific change in sales. B. Marginal cost is the change in total cost that comes from producing one more item (â€Å"Investopedia,† 2011). The reason why organizations need to find marginal cost is to determine when economies of scale can be achieved. 1. Total cost is the cost of producing all the units of production. It is important to know and understand the total cost because it will determine whether or not it is worth it to produce one more unit. The key is to find the optimal point and then do not produce more than the marginal cost allows. C. Profit it the total revenue made in a certain period of time divided by the total expenses or costs or that same time period. It is important to have as much profit as possible because it determines the financial health of a business. 1. Profit maximization is achieved at the point where marginal revenue equals marginal cost. This is the optimal point of production because any change, whether an increase or decrease, would result in less profit for a firm, and thus not achieving profit maximization. D. Profit maximization is the output and price of a certain product that achieves the greatest amount of profit for a firm. The can be found be determining looking at a graph that contains marginal revenue and marginal cost as its axes. The point where these two lines intersect is where profit maximization can be attained. E. If marginal revenue happens to be greater than marginal cost, then a profit maximising firm must increase production until the marginal cost and marginal revenue is the same. This is because if more products are produced, then less marginal revenue can be gained, thus decreasing marginal revenue to a point where it is equal with marginal cost. F. On the other hand, if marginal revenue happens to be less than marginal cost, then a firm must decrease production until marginal revenue and marginal cost

Pollution - Assignment Example Some examples of air pollution include: Exhaust from motor vehicles and airplanes - The combustion of fuels in the engines releases exhaust gases such as carbon monoxide, carbon dioxide, sulfur dioxide and in some cases lead particles into the air. This is the addition of contaminants in water bodies that result in a significant change in physical, chemical or biological state of the water. The resultant effect of contamination can be attributed to an increase in waterborne diseases, suspended sediments, and excessive growth of aquatic plants and death of aquatic animals (Hill, 2010). Some examples of water pollution include: This may take the form of either misuse of the land surface or disposal of both industrial and household waste. Some forms of land misuse are seen in improper agricultural practices and in mineral exploitation (Hill, 2010). Land pollution may be visible or invisible as a result of seepage of the pollutants. The latter is very hard to clean up since the contaminants may be spread over a large area. Some examples of land pollution include: This is the presence of unattractive sites in the human vicinity. This form of pollution is subjective in nature since individuals possess different views in what they term as either attractive or unattractive (Meunier, 2010). Some examples of visual pollution include: I consider water pollution the worst since contamination on one point is spread over to other areas for example pollution of river water can have serious consequences downstream. In addition, water is crucial for the survival of all living things. Thus water pollution affects a wide range of living organism and destruction or death of aquatic organism. Lastly, sometimes it is not easy to know if the water has been contaminated for example, contamination from heavy metals which requires laboratory testing. Pests cause health and economic problems depending on their types and where they inflict their damage. In

Homeland Security Preparedness Essay Example | Topics and Well Written Essays - 2250 words

Homeland Security Preparedness - Essay Example â€Å"The role of state and local governments as well as the nation's first responder community has been viewed largely as providing quick reaction and consequence mitigation to any attacks that occur despite the best effort of the federal system to prevent it...In fact, this image is not correct; local governments must do a great deal more than prepare for the consequence management role. In particular, they must also pay a great deal of attention to prevention efforts. To date they have not done nearly enough in this regard† (O'Hanlon, 2005). O'Hanlon recommends that state and local governments can be first responders in all arenas. The Governor's office should make sure that there is a dedicated anti-terrorism task force at the state level, and any sufficiently large cities should have an anti-terrorism task force operating out of a major crimes unit. Local miscommunication and planning was part of the slow response to 9/11. According to the 9/11 Commission Report, â€Å"[ A] 'generic' flight plan – prepared to get the aircraft airborne and out of local airspace quickly – incorrectly led the Langley fighters to believe they were ordered to fly due east... for 60 miles... the lead pilot and local FAA controller incorrectly assumed the flight plan instruction to go '090 for 60' superseded the original scramble order† (p. 27). Inadequate protocols for communication and coordination between local, state and federal authorities can have lethal consequences. Similarly, the FBI's limited terrorism response pre-9/11 was due to their being tied too closely with state and local agencies such that they were only interested in pursuing the needs of state and local areas such as organized crime and white-collar offenses (p. 74). O'Hanlon notes that state governments do not have to do everything and be everywhere. â€Å"it is not necessary to equip all three million first responders in the United States with state of the art chemical protective gear or interoperable communications systems. Equipping specialized teams within each major jurisdiction with such capabilities, and creating several mobile communications headquarters with interoperable technology, are less expensive and more quickly doable propositions. It is not necessary that every fireman’s radio can talk to every police officer’s radio; a certain number of mobile interoperable communications vans that can be quickly deployed to a problem site are a more cost-effective solution. They can allow quick coordination and cross-communication through the squad or team leaders of each type of organization (that would have been enough to save many firefighters on September 11, 2001 in New York). A large city could purchase several dozen, at $1 million each, for a reasonable cost of several tens of millions of dollars† (O'Hanlon, 2005). The Governor's Office should follow this approach. While all EMS and medical responders, police units, hospitals an d other state agencies do not need to have extensive anti-terror preparation, specialized units should and should have access to top-of-the line gear. As O'Hanlon illustrates, doing so not only is cost-effective but in any respect is often fungible to every day operations: Communications vans like the one above can also be used in major crimes like bank robberies. O'Hanlon recommends $5 billion

Dark Chocolate Essay Example for Free

Dark Chocolate Essay Chemistry Central Journal brings even more good news for chocolate lovers, stating that dark chocolate contains more flavanols and polyphenols than fruit juice. Cacao seeds are a Super Fruit providing nutritive value beyond that of their macronutrient composition, said Dr Debra Miller. Chocolate and Blood Pressure The important thing is that the antioxidants in dark chocolate can significantly reduce blood pressure in patients with hypertension. According to researchers from the University of Adelaide, flavanols promote vasodilation, which may consequently lower blood pressure. There have, however, been conflicting results as to the real-life effects of eating chocolate. Weve found that consumption can significantly, albeit modestly, reduce blood pressure for people with high blood pressure but not for people with normal blood pressure. added Dr Karin Ried, who is program manager and research fellow of the PHCRED (Primary Health Care Research Evaluation Development) program at The University of Adelaide. The analysis concluded that the pressure reduction caused by chocolate consumption was comparable to the effects of 30 minutes of daily physical activity. Chocolate and Cirrhosis There are also potential benefits for liver disease patients. Spanish scientists found that eating dark chocolate lowers blood pressure in the liver and reduces damage to the blood vessels of patients with cirrhosis. A study which was presented at the International Liver Congress 2010 divided 21 cirrhotic patients with end stage liver disease into two groups. The first group received liquid meal containing dark chocolate, while the participants in the second group were getting liquid meal with white chocolate devoid of anti-oxidant properties. As a result, the patients receiving dark chocolate experienced a noticeable reduction of post-prandial increase in blood pressure in the liver. one Square Is Enough However, it is not necessary to eat huge quantities of chocolate in order to experience all the health benefits. In fact, just one small square a day may be enough to experience the health benefits chocolate is offering. A study performed in Germany that compared 19 357 individuals found that those who ate the most amount of chocolate (an average of 7.5 grams a day) were at a 39% lower risk of developing a heart attack than people with the lowest (1.7 grams) chocolate intakes. To put things into perspective, the six grams of difference are the equivalent of one small square of a typical 100g chocolate bar. Our hypothesis was that because chocolate appears to have a pronounced effect on blood pressure, therefore chocolate consumption would lower the risk of strokes and heart attacks, explains Dr Brian Buijsse from the German Institute of Human Nutrition, who led the research. Small amounts of chocolate may help to prevent heart disease, but only if it replaces other energy-dense food, such as snacks, in order to keep body weight stable.

Theories for Causes of Aggressive Behaviour

Theories for Causes of Aggressive Behaviour Compare and contrast social and biological accounts of the causes of aggressive behaviour. Aggression is defined as: (a) ‘a quality of anger and determination that makes you ready to attack other people’; (b) ‘violent and attacking behaviour’ (Collins, 2003). Whereas love, friendship and affiliation are positive, adaptive and constructive social influences, aggression is associated with violence, antisocial behaviour and destruction. Examples of aggressive behaviour range from arguments, to road rage, terrorism and war. Aggression then is physical or verbal behaviour that is intended to harm another person. This work examines aggressive behaviour in terms of biological and social-learning processes providing theoretical and research evidence. Ethologists like Konrad Lorenz (2002) have identified several human behaviours, including aggression, that allow animals to gather and keep the fundamental resources for survival, mating, reproducing and caring for children. Discovering, taking and holding a territory provides the background on which the life cycle occurs. Many animals engage in territorial signalling to defend their territory mostly for mating and feeding purposes. Territorial signalling is adaptive because it prevents potentially destructive aggressive behaviours. The majority of animal aggression is due to mating, therefore, natural selection predisposes animals towards aggressive behaviour. Male and female animals compete for mates and patterns of sexual behaviour help us understand various form of aggressive behaviour. Nevertheless, psychologists disagree about which of these biological inferences of other animals are relevant to humans. Evolutionary psychologists claim that they do apply to humans and postulate that territorial behaviour exists both in humans and in animals for the same reasons (Barkow, Cosmides Tooby, 1992). Most adults attempt to restrict their mate’s sexual activities, using territorial signalling and emotional displays. For example, jealousy and aggression during courtship and mating are seen in arguments (territorial signalling) and physical fighting (when signalling fails). This is obvious in that men in many cultures and subcultures continue to think of their wives as property – part of the territory they defend. Furthermore, comparison studies of identical twins that were brought up together and apart reveal a genetic effect on aggression. Twin studies (Miles Carey, 1997; Rowe, Almeida Jacobson, 1999) and the existence of gender differences (Buss Perry, 1992; Loeber Hay, 1997) support the idea that genes predispose a person towards being aggressive. The presence of the male hormone testosterone is also related to aggression. Laboratory experiments with mice and monkeys have shown that castration both lowers the levels of testosterone and aggressive behaviour. Contrary, the administration of testosterone to castrated animals and normal animals increase aggressive behaviour. Moreover, males who have been imprisoned for violent crimes and who are more violent than others while imprisoned, have higher testosterone levels than less violent prisoners (Dabbs, Carr, Frady Riad, 1995). In order to be able to decide effectively whether children learn aggressive behaviour, the theories of aggression which claim that it is an innate capacity will be considered. The view that aggression is innate comes from the fact that few parents actually teach their children to be aggressive. However, Bandura’s (1971) early work indicated that children who have seen another person behaving aggressively will be increasingly likely to demonstrate aggressive behaviour. Later he proposed that aggression is actually something we learn to demonstrate because it seems to be useful to us. The likelihood of children imitating the behaviour will increase if they see the person being rewarded (reinforced) for their aggression by getting what they want. For example, a child who has become a very aggressive bully at school because he has learned that he will get what he wants. Where has he learned to be aggressive? Bandura (1971) argues that children learn by seeing others behaving aggre ssively during their childhood, or adolescence, through their own experience of being bullied or through observation of the media. Knowing that we learn by observation is relevant to what we see on television. A number of studies have been conducted to discover whether television and cinema violence really does result in violent behaviour. Bandura (1971) reported that children who watched a video of other children punching an inflated stand-up toy (a ‘Bobo doll’) were more likely than others to behave in the same way when given the opportunity. In a follow-up to Bandura’s studies, children who watched ‘Mighty Morphin Power Rangers’ later imitated these character’s Karate kicks and mimicked their violent acts during play sessions with peers (Boyatzis, Matillo Nesbitt, 1995). Considering boys play which tends to include wrestling and fighting, Geary (1999) has claimed that play patterns represent an evolved adaptation that prepares boys for hunting and primitive warfare. Several researchers have reported short-term effects of television violence: young children (Singer Singer, 1986) and adolescents (Wood et al., 1991) behaved more aggressively immediately after watching a violent TV program. The causes of their immediate changes in behaviour were probably a result of heightened arousal and desensitisation from repeated viewings (Gunter McAleer, 1990). Overall, however, research results have been equivocal, suggesting to some psychologists that TV violence may cause less harm than first suspected (McGuire, 1986). Furthermore, environmental influences have been viewed as determinants of aggression. According to the frustration-aggression hypothesis, a person is more likely to become aggressive when frustrated; therefore, aggression is a predictable response to frustration (Dollard, Doob, Miller, Mower Sears, 1939). This theory, though, by itself does not predict aggressive behaviour but, for example, hot weather makes people uncomfortable and this result into some people behaving aggressively. Triandis (1994) claimed that the relationship between heat and violence is confounded by the gap between rich and poor and by single parent families. On the whole, research evidence supports that both biological and social learning approaches explain aggressive behaviour as internal and external influences respectively. Twin studies and differences in the way boys and girls play indicate a strong biological foundation for aggressive behaviour. People with higher levels of testosterone are more aggressive than those with lower levels. In addition, heat, poor economic conditions and TV violence are all associated with increases in violent behaviour. Nevertheless, it has been argued that some cultures are more aggressive than others. A person is 80 percent less likely to be murdered in Canada than in the United States (United Nations, 1997). The socio-biological approach postulates that genes interact with culture to produce unique examples of aggressive behaviour. References Bandura, A. (1971). Social learning theory.
