Insecticides essays

Insecticides essays An insecticide is used to kill insects. There are many kinds of insecticides, but organic insecticides are the most commonly used (World Book, 1999). Organic insecticides are split into three different categories: Chlorinated hydrocarbon insecticides, organophosphate insecticides, and carbamate insecticides (World Book, 1999). In this paper, I'll explore how toxic each of these insecticides are, how they affect wildlife, humans, and the environment, and what we can do to help. Some insects, like white flies and mosquitoes, can carry deadly diseases that affect crops, animals and humans. Insects can cause about 5.5 billion dollars in crop and live stock losses every year. Some of the diseases they cause are Cattle Fever and Sheep Scab. The insecticides are used to kill insects and protect livestock (World Book, 1999). Insecticides can also be used on flea treatments for cats, dogs, and other animals (Ackerman, 1996). Organic Insecticides are the most commonly and widely used insecticides. They are synthetic substances made from carbon, hydrocarbon insecticies, organophosphate insecticides (World Book 1999). Chlorinated hydrocarbon insecticides, also know as "organic chlorines", contain chlorine atoms (World Book 1999). Common members of this group are Acaralate, Acarol, Aldrin, BHC, Chlordance, Chlorobenzilate, DDT, dicofol, dieldrin, endosulfan, endrin, heptachlor, kepone, lindane, methoxychlor, mirex, perthen, TDE, and toxaphene (Hamm 1982). They're persistant because after being used once, they can still affect living things for several years. This is because they don't break down chemically so they're found in soil, animal and fish tissue, plants, and water (Hamm, 1982). These, and all persistant insecticides, are trying to be replaced and restricted because they kill bird, fish, and other animals (World Book, 1999). Organophospahte Insecticides contain phosphorus atom (World Book, 1999). Common members o...

The Future of Psychology Paper - Essay Example The last two decades of the century saw the recognition of psychology as not only a science but also as a practice. Thus, contemporary psychology is loosely defined as the study of behavior and all other underlying mental phenomena, reflecting a wider and more integrated, interdisciplinary body of science (APA Monitor Online, Vol. 30, #11, Dec. 1999). Finding its place in contemporary society which has likewise kept evolving, psychology as the world knows and embraces it today has taken the form of self-help, advices, and of concepts like the enneagram, â€Å"inner child†, â€Å"left/right brain†, among others. This is what is categorized now as popular psychology or pop psychology. By definition, popular psychology deals with concepts and theories pertaining to human mental life and behavior that are claimed to be psychology-based. These easily become popular among people because they provide easily-understood explanations that are not known before, and they present theories that are specifically addressing very personal and pressing issues like marriage relationships, parenting, the whys and how-to’s of things. In other words, they offer comprehensible explanations for interesting issues in a manner that even ordinary housewives, teenagers, everyday folks can easily accept and digest. The proliferation of self-help books as part of pop psychology has been a growing industry. An example and the most successful self-help book is â€Å"The Road Less Travelled† by M. Scot Peck, which presents psychology-based explanations about very interesting subjects in life, like love, marriage, parenting, self-growth and development. With the success of this book, several others have followed suit, thus â€Å"how-to† and â€Å"why† books about almost anything that interests the human mind are available. Although they provide better understanding of things, presenting easy-to-digest explanations with basis on psychology, these self-help books also present potential

The Economic Reality of Hybrid Vehicles Essay Example for Free

The Economic Reality of Hybrid Vehicles Essay The high price of gas at the pump has many Americans looking for alternates to their gas powered vehicles. One of the most popular option right now is a hybrid vehicle. The question that comes to mind is, are hybrid vehicles worth it? With record high gas prices due to the price of oil, most car owners out there have major concerns over their gas usage. Over the past ten years, the cost of gasoline has grown 250%! The price of oil has doubled since January of this year. The high prices of oil and gas is the driving factor for most of the people to trade their gas powered vehicles for hybrid vehicles. These vehicles promise to give consumers more mileage per gallon, the truth is that only a few vehicles currently in the market actually make any sort of financial sense. There are quite a few issues with buying hybrid vehicles, even with gas prices at more than $4 a gallon. First, these vehicles are much higher in price than their gas powered counter part so, the premiums attached to their price tags do not justify extra mileage that you get. In some cases car dealers are selling popular vehicles at much higher prices than MSRP. Second, there are no laws and regulations controlling the technology, price, and the mileage per gallon required out of these vehicles. Currently, there are hybrid vehicles in the market that offer an improvement of 3MPG to 18 MPG over their gas powered counterpart. This is a huge range that needs to be controlled. Third, the demand of these vehicles is driving the prices of the vehicles even higher, if people knew that it would take many years for fuel savings to pay back the hybrid premium on many models, the demand on these models would be much lower, driving the prices down. The solutions that I would like to propose is the government to work with auto manufacturers to develop a standard for hybrid vehicles. This standard should control the minimum mileage offered per gallon, and control the premium allowed to be charged by the manufacturers. There are vehicles in the market that offer only a marginal benefit over the gas powered vehicles and yet the manufacturers charge thousands of dollars premium. Background: Today people all around the world are facing unusually high oil price hikes. Oil has become so very expensive that people are trying all kinds of extreme measures to lower the price. The hike in price has affected every nation; the entire world is trying to find a way out of the soaring prices. Thanks to the oil prices, travel expenses have increased, not just flying being expensive, driving your own car is very expensive. The chart below shows a trend in oil prices since 1990 with some of the major events leading to this increase. Note that since January of 2007 the oil prices have increase by 162%. With high gas prices, hybrid cars are a more affordable option than ever in terms of gas mileage, but only a handful of hybrid cars make solid financial sense, and only for some consumers, according to a new study by NADAguides. com, a vehicle pricing and information website. Using current gas prices for ten major metropolitan areas, the company studied the number of miles needed to recoup the extra cost of buying a hybrid car over its gasoline-only counterpart. The study showed, for example, that a driver in Los Angeles, the city with the highest gas prices in the study, will break even about 18 percent faster than a driver in Houston, the city with the lowest gas prices, assuming both are driving the same miles. The study found that, even at todays high gas prices, only a handful of hybrid cars make financial sense for a consumer who buys a new car every five years or less and drives an average number of miles per year. Even at Los Angeles-area gas prices, there are only five hybrid cars that would allow consumers to recoup their additional investment before they sold the car, assuming they drive an average of 15,000 miles per year. In order of shortest time to break even, they are: 1. Toyota Camry Hybrid 2. Chevrolet Malibu Hybrid 3. Nissan Altima Hybrid 4. Toyota Prius 5. Honda Civic Hybrid Following is a chart of the top five hybrid cars with the greatest return on investment and the number of miles to break even in 10 major metropolitan areas at current gas prices. Issue: Even with gas prices at more than $4 per gallon, there are quite a few issues with buying hybrid vehicles. Issue 1: High Prices Hybrid vehicle prices are higher than their gas powered counterpart. The demand for these vehicles in the last year has increased a lot, increasing the prices even further. In some areas people are actually paying premium over MSRP and waiting for more than two years to get some vehicles. The price premium attached to the hybrid vehicles are just too great to be considered a cost savings relative to purchasing their gasoline counterpart. If people knew how long it would take them to pay off the increased premium the demand for the hybrid would be lower than what it is now, decreasing the prices. Issue 2: High Prices The second issue with the hybrid vehicles is that there are no laws and regulations controlling the technology, price, and the mileage per gallon required out of these vehicles. Currently, there are hybrid vehicles in the market that offer an improvement of just a few miles per gallon over their gas powered counterpart, yet the manufacturers are charging thousands more for the premium for a so called hybrid technology. The table shows the amount of time it would take a buyer to offset the hybrid premium by fuel savings. The table also shows the miles per gallon and annual gas savings. These numbers clearly show the need to have some regulations to control the miles per gallon offered and the amount of premium that is charged by the manufacturers. Let’s look at some vehicles: Starting with the worst of the bunch, the Lexus LS600H. The premium charges on this vehicle is about $19,000, yet it only offers about 20 to 22 miles per gallon. It would take almost a century to break even. The next worst seems to be the Saturn Aura which only offers an annual gas savings of $171. The best one seems to Toyota Prius, but this car is so popular these days that in some areas there is a wait list of two years. In areas where it’s available, the dealers are charging more than $5,000 over MSRP. Solution: ?Better education to customers about the ownership costs of a hybrid vehicle ? Government should offer incentives like tax break to buy hybrid vehicles ? Have a standard to develop hybrid vehicle to encourage mass production, bringing the vehicle prices to even less than current gas-powered vehicles ? Force auto makers to sell hybrid vehicles at no more than, about 10%, premium to the customers Conclusion: Reference: Web Site: Bespoke Investing Group http://bespokeinvest. typepad. com/bespoke/.

Minority entrepreneurs have many barriers they have to overcome in order to be successful. Some typical problems they face are limited access to capital, lower equity investments, and less exposure to entrepreneurship. Minority entrepreneurs are twice as likely to be turned down for traditional lending, which can discourage them from even applying for a loan. Not only that but they are less likely to be considered by traditional or angel investors. They also generally live in run down areas, with poor schooling and less access to successful people. One entrepreneur who has hurdled over all the barriers and became extremely successful is Russell Simmons, the co-founder of Def Jam Records. Biography of Russell Simmons Russell Simmons was born in Queens, New York, on October 4, 1957. Growing up in Queens, he spent part of his adolescent years as a street hustler. During his middle school years, he sold marijuana and was even a member of a local gang. He was arrested twice on other charges and was given probation. At eighteen he began taking college classes in the New York area and started working at an Oranje Julius, but financed his clubbing lifestyle by selling fake cocaine. One night in 1977 while at a club he saw the clubbers going crazy over a song from Eddie Cheeba, an early rapper and DJ, he decided that it was the sound of the future. Simmons quit selling fake drugs and left college to begin promoting concerts and forming his own management company for artists. He called his company Rush Management. He managed Kurtis Blow, and Run-D.M.C.. In 1884 he partnered with Rick Ruban and founded Def Jam Recordings and starting the cultural revolution known as hip-hop. Businesses & Industries  ¬Ã‚ ¬Russell Simmons has his fingers in a ... ...nced everything from music to finance and philanthropy. He has been the architect in creating the trends in current pop culture. A majority of Simmons’ endeavors would fall into the venture opportunity school of thought, and he took an integrative approach. My Thoughts Simmons built an entertainment empire, with hip-hop at the foundation. By fighting for hip-hop, even when everyone said it was a fad Simmons taught me that, even if everyone doubts something, all it will take is one person to believe and to fight for what they believe in. I also learned that if one person starts to work towards a goal, it would pave the way for others to follow. Simmons often said that â€Å"Black culture or urban culture is for all people who buy into it and not just for black people. Whether it’s film or TV or records or advertisement or clothing, I don’t accept the box they put me in.†

Are Humans Innately Evil or Good? Essay

Humans are a very fascinating species. We have been ruling the Earth for quite a while now. This is because we brood over all our necessities, skills and looks. The question of if we are innately evil or good has been asked by numerous people since civilization. Everyone has had different opinions. Two famous philosophers by the names of Thomas Hobbes and John Locke have been known to answer this question in a brief and direct way. Thomas Hobbes and John Locke have lived between the years of 1500-1700’s in Europe. Locke was an English philosopher, political theorist, and found of Empiricism. They both have clashing and different opinions, but in my opinion I would have to agree with John Locke. Locke was born on August 29, 1632 in Wrington, England. He died on October 28, 1704. He was best known as an English philosopher and the author of Essay Concerning Human Understanding. Every human being is born good, they have a clean record, and they don’t know anything. Originally we were all in a state of nature. Parents, friends, relatives, societies, and the community influence us to do what they do. As we tend to grow up we will see murdering, stealing, taking drugs, and fighting all around us. Things like money and material possessions create jealousy and greed. Even if people are naturally good, the fact that some people have more than others creates problems. For example if one person is more rich than the other, the other person may at one point get jealous, and may perhaps do some unscrupulous things to the person, like steal from them, hate on them etc. We never knew about any of the bad things in the world, and neither did our ancestors. They were never natural instinctive traits. I think that Locke believed that humans are innately good because he probably grew up in a good neighborhood and had a good experience growing up. If one grows up in a very beautiful, safe, and well-mannered community and family, obviously they will do what their surrounding do, which is to do good. On the other hand, if one grows up to live in an incapacitated family and environment, he will tend to become evil, they will first watch and then they will mimic those same traits. Even though they do all of this, we humans will still have our conscience to tell us that what we are about to do is stupid or immature and we will regret it later on. Why would we bother setting up cities, going about helping others, reviewing where planet earth sits in its ability to survive if he didn’t want these things to do well? Sure there are people round that make it bad for all the others of us trying to do good, but weigh it up and you’ll see that only a small percentage of people are out to pull the curtain down on everyone else. If us humans were born evil, then why when we do the bad things that we do in life still feel the guilt and regret for it afterwards? Obviously the answer to this is because we aren’t evil; we just get influenced to become evil. In conclusion every single human was born good and even if they do get influenced to become evil they will still have all the regret, conscience, guilt, repentance, and shame on their shoulders to carry.

The Lottery by Shirley Jackson - 1325 Words

In â€Å"The Lottery†, Jackson wrote about a special tradition of a small village. June 27th was warm and sunny, and it gave the impression like nothing could possibly go wrong. Everyone knows the lottery as an exciting thing, and everybody wants to win, but this lottery is unlike any other. This lottery was actually the tradition of stoning of an innocent villager; that year it was Tessie Hutchinson. Though the horrific ending was not expected, throughout the story Jackson gave subtle hints that this was not an average lottery. Jackson foreshadowed the death of Tessie Hutchinson with stones, the black box, and the three legged stool; she showed that unquestioning support of tradition can be fatal. The stones played of one the largest parts†¦show more content†¦The box symbolized the anticipation of death, but it is treated as an everyday object. The three legged stool was the most unobtrusive out of the three. Jackson made it obvious that the villagers were frighten ed by the object, â€Å"The villagers kept their distance, leaving a space between themselves and the stool† (Jackson). Jackson gave an ominous vibe about the box; the reader have should notice the uneasiness the villagers feel. The stool was equally as significant as the black box, â€Å"It would thus seem that the stool is at least as important as the box: in my opinion, it is the symbol which holds the key the Jackson’s conclusive theme† (Nebeker). Nebeker explains the importance of the stool and how it symbolizes the Christian trinity: Now we understand the significance of the three-legged stool—as old as the tripod of the Delphic oracle, as new as the Christian trinity. For that which supports the present day box of meaningless and perverted superstition is the body of unexamined tradition or at least six thousand years of mans history. Some of these traditions (one leg of the stool if you like), are as old as the memory of man and are symb olized by the season, the ritual, the original box, the wood chips, the names of Summers, Graves, Martin, Warner (all cultures have their priesthoods!).
