Paints essays

Paints essays I Kayla J. R, am writing you, the National American International Livestock Exposition in order to attempt to persuade you to include our personal favorite breed of horse into your Exposition. This is our reasoning: The different patterns and the different colors will give a larger variety of choices for the judges. The different patterns may even have their own categories. Each and every paint has its own little history and own attitudes. Not only that, but they have a very pretty body type with obvious muscles. If you add them to your show, they need not have the World Championship Paint Horse Show, resulting in more money left over for the horses real needs such as food, tack, water and supplements. Read on to learn some great information on the Paint Breed. In 1519 a Spanish explorer Hernando Cortes sailed to North America with some conquistadors and horses only to leave behind a great legacy-which was the bloodstock that would provide the foundation for a variety of different, distinct, American-bred horses. A Spanish historian Diaz del Castillo who traveled with the entire expedition says that one of the sixteen war horses that carried Cortes and his men was a sorrel and white horse with spots on its belly. That spotted horse soon bred with Native American mustangs and laid the foundation for what is known today as the American paint horse breed. Near the early 1800s, the western plains were heavily populated with free-ranging herds of horses. These herds included a peculiar spotted horse. The spotted, flashy horses soon became a favorite mount of the American Indians because of the color and performance. The Comanche Indians, also known as the finest horsemen on the plains, favored the different colored horses and had a lot among their huge herds. The favoritism is exhibited in evidence by drawings of spotted horses on the painted buffalo robes that served as records for the Comanches. During the 180...

All About the Rock Called Chert

All About the Rock Called Chert Chert is the name for a widespread type of sedimentary rock that is made of silica (silicon dioxide or SiO2). The most familiar silica mineral is quartz in microscopic or even invisible crystals- that is, microcrystalline or cryptocrystalline quartz. Learn more about how it is made and find out what it is made of. Chert Ingredients Like other sedimentary rocks, chert starts with particles accumulating. In this case, it happened in bodies of water. The particles are the skeletons (called tests) of plankton, microscopic creatures that spend their lives floating in the water column. Plankton secrete their tests using one of two substances that are dissolved in water: calcium carbonate or silica. When the organisms die, their tests sink to the bottom and accumulate in a growing blanket of microscopic sediment called ooze. Ooze is usually a mixture of plankton tests and extremely fine-grained clay minerals. A clay ooze, of course, eventually becomes claystone. An ooze that is primarily calcium carbonate (aragonite or calcite), a calcareous ooze, typically turns into a rock of the limestone group. Chert is derived from a siliceous ooze. The composition of ooze depends on details of geography: ocean currents, the availability of nutrients in the water, world climate, depth in the ocean, and other factors. Siliceous ooze is mostly made of the tests of diatoms (one-celled algae) and radiolarians (one-celled animals or protists). These organisms build their tests of completely uncrystallized (amorphous) silica. Other minor sources of silica skeletons include the particles made by sponges (spicules) and land plants (phytoliths). Siliceous ooze tends to form in cold, deep water because calcareous tests dissolve in those conditions. Chert Formation and Precursors Siliceous ooze turns to chert by going through a slow transformation unlike that of most other rocks. The lithification and diagenesis of chert is an elaborate process.   In some settings, siliceous ooze is pure enough to lithify into a lightweight, minimally processed rock, called diatomite if composed of diatoms, or radiolarite if made of radiolarians. The amorphous silica of a plankton test is not stable outside the living things that make it. It seeks to crystallize, and as ooze is buried to depths greater than 100 meters or so, the silica begins to mobilize with the modest rise in pressure and temperature. There is plenty of pore space and water for this to happen, and plenty of chemical energy being released by crystallization as well as by the breakdown of organic matter in the ooze. The first product of this activity is a hydrated silica (opal) called opal-CT because it resembles cristobalite (C) and tridymite (T) in X-ray studies. In those minerals, silicon and oxygen atoms align with water molecules in a different arrangement than that of quartz. A less-processed version of opal-CT is what makes up with water molecules in a different arrangement than that of quartz. A less-processed version of opal-CT is what makes up common opal. A more processed version of opal-CT is often called opal-C because in X-rays it looks more like cristobalite. The rock composed of lithified opal-CT or opal-C is porcellanite. More diagenesis causes the silica to lose most of its water as it fills pore space in the siliceous sediment. This activity converts the silica into true quartz, in microcrystalline or cryptocrystalline form, also known as the mineral chalcedony. When that happens, chert is formed. Chert Attributes and Signs Chert is as hard as crystalline quartz with a hardness rating of seven  in the Mohs scale   maybe a bit softer, 6.5, if it still has some hydrated silica in it. Beyond simply being hard, chert is a tough rock. It stands above the landscape in outcrops that resist erosion. Oil drillers dread it because its so hard to penetrate. Chert has a curvy conchoidal fracture that is smoother and less splintery than the conchoidal fracture of pure quartz; ancient toolmakers favored it, and high-quality rock was a trade item between tribes. Unlike quartz, chert is never transparent and not always translucent. It has a waxy or resinous luster unlike the glassy luster of quartz.   The colors of chert range from white through red and brown to black, depending on how much clay or organic matter it contains. It often has some sign of its sedimentary origin, such as bedding and other sedimentary structures or microfossils. They may be abundant enough for a chert to get a special name, as in the red radiolarian chert carried to land by plate tectonics from the central ocean floor. Special Cherts Chert is a quite general term for noncrystalline siliceous rocks, and some subtypes have their own names and stories. In mixed calcareous and siliceous sediments, the carbonate and the silica tend to segregate. Chalk beds, the calcareous equivalent of diatomites, may grow lumpy nodules of chert of the type called flint. (Similarly, thick chert beds may grow nodules and pods of limer ock limestone or dolomite rock.) Flint is commonly dark and gray, and more lustrous than typical chert. Agate and Jasper are cherts that form outside the deep-sea setting; they occur where fractures allowed silica-rich solutions to enter and deposit chalcedony. Agate is pure and translucent whereas Jasper is opaque. Both stones commonly have reddish colors from the presence of iron oxide minerals. The peculiar ancient banded iron formations consist of thin layers of interbedded chert and solid hematite. Some important fossil localities are in chert. The Rhynie Cherts in Scotland contain remains of the oldest land ecosystem from nearly 400 million years ago early in the Devonian Period. And the Gunflint Chert, a unit of banded iron formation in western Ontario is famous for its fossil microbes, dating from the Early Proterozoic time some two billion years ago.

Scientific Method - Social Psychology Essay Example | Topics and Well Written Essays - 250 words

Scientific Method - Social Psychology - Essay Example Scientific method is highly instrumental to the success of social psychologists in carrying out their analysis. It is the application of scientific method of systematic observation that the conditions of humans are effectively studied. Through the scientific method of research, social psychologists are better informed on the way people feel, how they behave and the kind of thoughts that go through their minds (Feldman, 2009). Social psychologists cannot make observation without the use of scientific method and research as they make use of the advancement in technology to make precise and intricate observations about their subjects. This further emphasizes the role of scientific method in the field of social psychology as the more the improvement in research technology, the easier and faster the work of social psychologists would definitely be. It is therefore pertinent to note that social psychologists make use of different scientific methods of research, which includes; public opini on surveys, real world observations, case studies, and laboratory experiments to make their analysis and study. This further corroborates the role of scientific method in social psychology.

Research a civil society organistain and detail its main tactics and Assignment

Research a civil society organistain and detail its main tactics and approached in regards to business - Assignment Example CSOs are the legally constituted corporations created by natural or legal people for the purpose of societal welfare (Craig, Taylor and Parkes, 2004). However, these establishments work independently from the government. One of the major characteristics of CSOs or NGOs is that these forms of establishments are non profitable organizations. Hence, their principal aim is not to make profits but to look after the welfare of people (Fine, 2006). This report aims at illustrating the main tactics and approaches used by a CSO in its relationship with business. In addition, the report also aims to summarise if and to what extent its tactics have evolved over time and will elucidate the discernible changes in the tactics. Lastly the study will evaluate the strategies used by the CSO and on the basis of that recommendation will be provided to the CSO in terms of improving or strengthening its activities (Barratt, 2009; Child and Gronbjerg, 2007). The civil society organizations or the non-gove rnmental organization chosen for this study is Mercy Corps. Therefore for better understanding, the study will at first present a brief overview of the chosen CSO. Mercy Corps: A Brief Overview Mercy Corps is an international aid agency which works towards the betterment of transitional environments that has gone through certain kinds of jolts such as natural disaster, economic collapse, or conflicts. The principal intention of this CSO is to assist people who have been a victim of the environmental collapse. It was founded in the year 1979 by humanitarian Ellsworth Culver and Dan O'Neill (Bonn and Baker, 2000). The establishment is currently headquartered in Portland, Oregon and is currently headed by Neal Keny-Guyer, who is the present CEO of the company. It has around 3700 employees and operates in 40 countries around the world (mercycorps, 2013a). The employees of the company attempt to aid victimised people on an urgent basis. For instance, the employees try to bring in food an d supplies as early as possible in order to enable the people restore their previous situation. This is achieved by various kinds of market-led and community-driven programs. The activities of the employees clearly reflect the enthusiasm of the organization towards the welfare of the society. Mercy Corps mostly recruits local people. As per reports, the company has 93% local employees as they believe local employees will be beneficial for their local knowledge. The CSO works for the betterment of failing states, conflict zones and nations that endured natural disasters. It remains active in places such as Zimbabwe, Somalia, Congo, Afghanistan, Iraq, Pakistan, Haiti and Indonesia among others (Bichsel, 2008). In these countries, women education is usually ignored, livelihood of a family is a matter of doubt and a child’s health is always a cause of concern. Hence, to get rid of these issues, the CSO works proactively and responds immediately. Mercy Corps prioritizes its activi ties on the basis of the urgency of the situation and also listens to the local inhabitants (Migdalovitz, 2010). Interestingly, Mercy Corps caters an area or locality for extended time periods in order to foster local entrepreneurship opportunities, inspire marketplaces through "cash for work" programs and a range of lending models for rebuilding social capital. Mercy Corps initiates several programs which allow them to gain market reputation and simultaneously

Private Security Essay Example for Free

Private Security Essay It seems that the criteria to be eligible for a private security officer post seems to be extensive that need several details of the applicant. Though the basic application requirements appear to be similar in both the book ‘Principles of Security and Crime Prevention’ and the Florida state instruction manual, the amount of information differs in relation to certain key points. Florida State’s requirements seem to be elaborative than that of the book.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Coming to the details, while the minimum age to be eligible for applying is 18 years in both the sources, it is further described as 18 for unarmed and 21 for armed private security officer (Collins, Ricks Meter, 2000, p. 104). Also, submission of address details is mentioned in the requirements of both the sources and it is further clarified in Florida’s manual as residence details of five years (Bronson, 2007). Moreover, the manual indicates that applicant should also furnish details of aliases, if any (Bronson, 2007). Employment details of 5years should be mentioned as per Florida State’s requirements, whereas it is 7 years in the book (Collins et al., 2000, p. 104).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The requirements regarding details of criminal history are almost similar in both the sources, which state that any kind of bad criminal record in the past 7-10 years may jeopardize the chances of the applicant (Bronson, 2007; Collins et al., 2000, p. 104). Moreover, Florida State’s requirements clearly mention a case of denial and a chance of denial of the application (Bronson, 2007). Criminal history related to disrespect towards country, government officials and/or involvement in dealings of controlled substances may result in rejection of the application. Also, Florida State requirements clearly state the need for applicants to submit all related documents in case of a previous conviction and that the verification of the applicant’s criminal record may take 1-3 months duration (Bronson, 2007).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The guidelines related to applicant’s mental fitness are explained more clearly in the Florida requirements. In Collins et al. book, the only point stated is the ineligibility of a person who is declared by the court as incompetent due to some mental disease (2000, p. 105). However, the state’s manual describes various points regarding the furnishing of details related to mental fitness by a candidate who has previously been diagnosed and/or treated for any mental illness and/or addiction (Bronson, 2007). The state manual requires the candidate to submit letters of reference if the candidate has alcohol or drug abuse and rehabilitation history; whereas Collin’s book simply states that the candidates have to undergo a pre-employment drug screen (Bronson, 2007; Collins et al., 2000, p. 104).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The Florida state’s criteria are very clear about training of the individual, making it mandatory to complete 40 hours of authorized training (Bronson, 2007). It has given the list of personalities who can be exempted from taking the training. Also, in the Collis et al. book, it is mentioned that a potential candidate for armed post should successfully complete a psychological fitness test (Collins et al., 2000, p. 105). While the state manual highlights the point of citizenship with related details, Collins book mentions about minimal desired education for the applicant (Bronson, 2007; Collins et al., 2000, p. 105). In this way, apart from common points, both the sources have mentioned various requirements and useful points. Florida’s manual even describes about conditions that permit exemptions from certain mandatory procedures. All in all, the Florida State’s manual is a comprehensive source with all instructions for an applicant and the Collins’ book is a useful aid to know basic requirements. References Bronson, C. H.

Native Son :: essays research papers

Character Actions Defines Their Individual Personalities and Belief Systems Richard Wright's novel, Native Son, consisted of various main and supporting characters to deliver an effective array of personalities and expression. Each character's action defines their individual personalities and belief systems. The main character of Native Son, Bigger Thomas has personality traits spanning various aspects of human nature including actions motivated by fear, quick temper, and a high degree of intelligence. Bigger, whom the novel revolves around, portrays various personality elements through his actions. Many of his actions suggest an overriding response to fear, which stems from his exposure to a harsh social climate in which a clear line between acceptable behavior for white's and black's exists. His swift anger and his destructive impulses stem from that fear and become apparent in the opening scene when he fiercely attacks a huge rat. The same murderous impulse appears when his secret dread of the delicatessen robbery impels him to commit a vicious assault on his friend Gus. Bigger commits both of the brutal murders not in rage or anger, but as a reaction to fear. His typical fear stems from being caught in the act of doing something socially unacceptable and being the subject of punishment. Although he later admits to Max that Mary Dalton's behavior toward him made him hate her, it is not hate which causes him to smother her to death, but a feeble attempt to evade the detectio n of her mother. The fear of being caught with a white woman overwhelmed his common sense and dictated his actions. When he attempted to murder Bessie, his motivation came from intense fear of the consequences of 2 "letting" her live. Bigger realized that he could not take Bessie with him or leave her behind and concluded that killing her could provide her only "merciful" end. The emotional forces that drive Bigger are conveyed by means other than his words. Besides reactions to fear, his actions demonstrate an extremely quick temper and destructive impulse as an integral part of his nature. Rage plays a key part in his basic nature, but does not directly motivate the murders he commits. Rage does not affect Bigger's intelligence and quick thinking and it becomes evident during the interview with Briton. The detective makes Bigger so angry that the interrogation becomes a game to Bigger, a game of logic and wills, of playing the stupid negro, and telling the man exactly what he wants to hear.

Business Math

Chapter 5 Interest Rates 5-1. Your bank is offering you an account that will pay 20% interest in total for a two-year deposit. Determine the equivalent discount rate for a period length of a. Six months. b. One year. c. One month. a. Since 6 months is [pic] of 2 years, using our rule [pic] So the equivalent 6 month rate is 4. 66%. b. Since one year is half of 2 years [pic] So the equivalent 1 year rate is 9. 54%. c. Since one month is [pic] of 2 years, using our rule [pic] So the equivalent 1 month rate is 0. 63%. 5-2. Which do you prefer: a bank account that pays 5% per year (EAR) for three years or a. An account that pays 2[pic] every six months for three years? b. An account that pays 7[pic] every 18 months for three years? c. An account that pays [pic] per month for three years? If you deposit $1 into a bank account that pays 5% per year for 3 years you will have [pic] after 3 years. a. If the account pays [pic] per 6 months then you will have [pic] after 3 years, so you prefer [ pic] every 6 months. b.If the account pays [pic] per 18 months then you will have [pic] after 3 years, so you prefer 5% per year. c. If the account pays [pic] per month then you will have [pic] after 3 years, so you prefer [pic] every month. 5-3. Many academic institutions offer a sabbatical policy. Every seven years a professor is given a year free of teaching and other administrative responsibilities at full pay. For a professor earning $70,000 per year who works for a total of 42 years, what is the present value of the amount she will earn while on sabbatical if the interest rate is 6% (EAR)? Timeline: 0 |7 |14 | | | |42 | | | | | | | | | |0 |1 |2 | | | |8 | | | | | | | | | |0 |1 |2 | | | |304 | | | | | | | |48 |0. 75 % |20,092. 9 |–500 |0 | Thus, your remaining balance is $20,092. 39. If you prepay an extra $100 today, your will lower your remaining balance to $20,092. 39 – 100 = $19,992. 39. Though your balance is reduced, your required monthly payment does not ch ange. Instead, you will pay off the loan faster; that is, it will reduce the payments you need to make at the very end of the loan. How much smaller will the final payment be? With the extra payment, the timeline changes: That is, we will pay off by paying $500 per month for 47 months, and some smaller amount, $500 – X, in the last month.To solve for X, recall that the PV of the remaining cash flows equals the outstanding balance when the loan interest rate is used as the discount rate: [pic] Solving for X gives [pic] So the final payment will be lower by $143. 14. You can also use the annuity spreadsheet to determine this solution. If you prepay $100 today, and make payments of $500 for 48 months, then your final balance at the end will be a credit of $143. 14: |N |I |PV |PMT |FV | |48 |0. 75 % |19,992. 9 |-500 |143. 14 | (2) The extra payment effectively lets us exchange $100 today for $143. 14 in four years. We claimed that the return on this investment should be the loan interest rate. Let’s see if this is the case: [pic], so it is. Thus, you earn a 9% APR (the rate on the loan). 5-19. Consider again the setting of Problem 18. Now that you realize your best investment is to prepay your student loan, you decide to prepay as much as you can each month. Looking at your budget, you can afford to pay an extra $250 per month in addition to your required monthly payments of $500, r $750 in total each month. How long will it take you to pay off the loan? The timeline in this case is: and we want to determine the number of monthly payments N that we will need to make. That is, we need to determine what length annuity with a monthly payment of $750 has the same present value as the loan balance, using the loan interest rate as the discount rate. As we did in Chapter 4, we set the outstanding balance equal to the present value of the loan payments and solve for N. [pic] We can also use the annuity spreadsheet to solve for N. N |I |PV |PMT |FV | |30. 02 |0. 75 % |20,092. 39 |–750 |0 | So, by prepaying the loan, we will pay off the loan in about 30 months or 2 ? years, rather than the four years originally scheduled. Because N of 30. 02 is larger than 30, we could either increase the 30th payment by a small amount or make a very small 31st payment. We can use the annuity spreadsheet to determine the remaining balance after 30 payments. N |I |PV |PMT |FV | |30 |0. 75 % |20,092. 39 |–750 |–13. 86 | If we make a final payment of $750. 00 + $13. 86 = $763. 86, the loan will be paid off in 30 months. 5-20. Oppenheimer Bank is offering a 30-year mortgage with an APR of 5. 25%. With this mortgage your monthly payments would be $2000 per month. In addition, Oppenheimer Bank offers you the following deal: Instead of making he monthly payment of $2000 every month, you can make half the payment every two weeks (so that you will make 52 ? 2 = 26 payments per year). With this plan, how long will it take to pay off the mortga ge of $150,000 if the EAR of the loan is unchanged? If we make [pic] every 2 weeks the timeline is as follows. Timeline: |0 |1 |2 |3 | | | | | | | | | | | | Using the formula for the loan payment, [pic] Next we write out the cash flows with the extra payment. Timeline #2: 0 |1 | |6|7| |18 | | | | | | | | | To determine the outstanding balance we discount at the original rate, i. e. , [pic] [pic] Next we calculate the loan payment on the new mortgage. Timeline #2: |0 |1 |2 | | | |360 | | | | | | | | | The discount rate on the new loan is the new loan rate: [pic] Using the formula for the loan payment: [pic] b. pic] c. [pic] (You can use trial and error or the annuity calculator to solve for N. ) d. [pic] (Note: results may differ slightly due to rounding. ) 5-24. You have credit card debt of $25,000 that has an APR (monthly compounding) of 15%. Each month you pay the minimum monthly payment only. You are required to pay only the outstanding interest. You have received an offer in the mail for an otherwise identical credit card with an APR of 12%. After considering all your alternatives, you decide to switch cards, roll over the outstanding balance on the old card into the new card, and borrow additional money as well.How much can you borrow today on the new card without changing the minimum monthly payment you will be required to pay? The discount rate on the original card is: [pic] Assuming that your current monthly payment is the interest that accrues, it equals: [pic] Timeline: |0 |1 |2 | | | | | | | | | | | | | | | | | | | |312. 50 |312. 50 | |This is a perpetuity. So the amount you can borrow at the new interest rate is this cash flow discounted at the new discount rate. The new discount rate is [pic] So,[pic] So by switching credit cards you are able to spend an extra [pic] You do not have to pay taxes on this amount of new borrowing, so this is your after-tax benefit of switching cards. 5-25. In 1975, interest rates were 7. 85% and the rate of inflation was 12. 3% in the United States. What was the real interest rate in 1975? How would the purchasing power of your savings have changed over the year? pic] The purchasing power of your savings declined by 3. 96% over the year. 5-26. If the rate of inflation is 5%, what nominal interest rate is necessary for you to earn a 3% real interest rate on your investment? [pic] implies [pic]. Therefore, a nominal rate of 8. 15% is required. 5-27. Can the nominal interest rate available to an investor be significantly negative? (Hint: Consider the interest rate earned from saving cash â€Å"under the mattress. †) Can the real interest rate be negative? Explain. By holding cash, an investor earns a nominal interest rate of 0%.Since an investor can always earn at least 0%, the nominal interest rate cannot be negative. The real interest rate can be negative, however. It is negative whenever the rate of inflation exceeds the nominal interest rate. 5-28. Consider a project that requires an ini tial investment of $100,000 and will produce a single cash flow of $150,000 in five years. a. What is the NPV of this project if the five-year interest rate is 5% (EAR)? b. What is the NPV of this project if the five-year interest rate is 10% (EAR)? c. What is the highest five-year interest rate such that this project is still profitable? . NPV = –100,000 + 150,000 / 1. 055 = $17,529. b. NPV = –100,000 + 150,000 / 1. 105 = –$6862. c. The answer is the IRR of the investment: IRR = (150,000 / 100,000)1/5 – 1 = 8. 45%. 5-29. Suppose the term structure of risk-free interest rates is as shown below: [pic] a. Calculate the present value of an investment that pays $1000 in two years and $2000 in five years for certain. b. Calculate the present value of receiving $500 per year, with certainty, at the end of the next five years. To find the rates for the missing years in the table, linearly interpolate between the years for which ou do know the rates. (For example , the rate in year 4 would be the average of the rate in year 3 and year 5. ) c. Calculate the present value of receiving $2300 per year, with certainty, for the next 20 years.

If you wanted to value this investment correctly using the annuity formula, which discount rate should you use? PV = 100 / 1. 0199 + 100 / 1. 02412 + 100 / 1. 02743 =$285. 61. To determine the single discount rate that would compute the value correctly, we solve the following for r: PV = 285. 1 = 100/(1 + r) + 100 / (1 + r)2 + 100/(1 + r)3 = $285. 61. This is just an IRR calculation. Using trial and error or the annuity calculator, r = 2. 50%. Note that this rate is between the 1, 2, and 3-yr rates given. 5-31. What is the shape of the yield curve given the term structure in Problem 29? What expectations are investors likely to have about future interest rates? The yield curve is increasing. This is often a sign that investors expect interest rates to rise in the future. 5-3 2. Suppose the current one-year interest rate is 6%.One year from now, you believe the economy will start to slow and the one-year interest rate will fall to 5%. In two years, you expect the economy to be in the midst of a recession, causing the Federal Reserve to cut interest rates drastically and the one-year interest rate to fall to 2%. The one-year interest rate will then rise to 3% the following year, and continue to rise by 1% per year until it returns to 6%, where it will remain from then on. a. If you were certain regarding these future interest rate changes, what two-year interest rate would be consistent with these expectations? . What current term structure of interest rates, for terms of 1 to 10 years, would be consistent with these expectations? c. Plot the yield curve in this case. How does the one-year interest rate compare to the 10-year interest rate? a. The one-year interest rate is 6%. If rates fall next year to 5%, then if you reinvest at this rate over two years you would earn (1. 06)(1. 05) = 1. 113 per dollar invested. This amount corresponds to an EAR of (1. 113)1/2 – 1 = 5. 50% per year for two years. Thus, the two-year rate that is consistent with these expectations is 5. 0%. b. We can apply the same logic for future years: c. We can plot the yield curve using the EARs in (b); note that the 10-year rate is below the 1-year rate (yield curve is inverted). 5-33. Figure 5. 4 shows that Wal-Mart’s five-year borrowing rate is 3. 1% and GE Capital’s is 10%. Which would you prefer? $500 from Wal-Mart paid today or a promise that the firm will pay you $700 in five years? Which would you choose if GE Capital offered you the same alternatives? We can use the interest rates each company must pay on a 5-year loan as the discount rate.PV for GE Capital = 700 / 1. 105 = $434. 64 < $500 today, so take the money now. PV for Wal-Mart = 700 / 1. 0315 = $600. 90 > $500 today, so take the promise. 5-34. Your best taxable investment o pportunity has an EAR of 4%. You best tax-free investment opportunity has an EAR of 3%. If your tax rate is 30%, which opportunity provides the higher after-tax interest rate? After-tax rate = 4%(1 – . 30) = 2. 8%, which is less than your tax-free investment with pays 3%. 5-35. Your uncle Fred just purchased a new boat.He brags to you about the low 7% interest rate (APR, monthly compounding) he obtained from the dealer. The rate is even lower than the rate he could have obtained on his home equity loan (8% APR, monthly compounding). If his tax rate is 25% and the interest on the home equity loan is tax deductible, which loan is truly cheaper? After-tax cost of home equity loan is 8%(1 – . 25) = 6%, which is cheaper than the dealer’s loan (for which interest is not tax-deductible). Thus, the home equity loan is cheaper. (Note that this could also be done in terms of EARs. ) 5-36.You are enrolling in an MBA program. To pay your tuition, you can either take out a s tandard student loan (so the interest payments are not tax deductible) with an EAR of 5[pic] or you can use a tax-deductible home equity loan with an APR (monthly) of 6%. You anticipate being in a very low tax bracket, so your tax rate will be only 15%. Which loan should you use? Using the formula to convert an APR to an EAR: [pic] So the home equity loan has an EAR of 6. 168%. Now since the rate on a tax deductible loan is a before-tax rate, we must convert this to an after-tax rate to compare it. [pic]Since the student loan has a larger after tax rate, you are better off using the home equity loan. 5-37. Your best friend consults you for investment advice. You learn that his tax rate is 35%, and he has the following current investments and debts:  ¦ A car loan with an outstanding balance of $5000 and a 4. 8% APR (monthly compounding)  ¦ Credit cards with an outstanding balance of $10,000 and a 14. 9% APR (monthly compounding)  ¦ A regular savings account with a $30,000 balan ce, paying a 5. 50% EAR  ¦ A money market savings account with a $100,000 balance, paying a 5. 25% APR (daily compounding) A tax-deductible home equity loan with an outstanding balance of $25,000 and a 5. 0% APR (monthly compounding) a. Which savings account pays a higher after-tax interest rate? b. Should your friend use his savings to pay off any of his outstanding debts? Explain. a. The regular savings account pays 5. 5% EAR, or 5. 5%(1 – . 35) = 3. 575% after tax. The money-market account pays (1 + 5. 25%/365)365 – 1 = 5. 39% or 5. 39%(1 – . 35) = 3. 50% after tax. Therefore, the regular savings account pays a higher rate. b. Your friend should pay off the credit card loans and the car loan, since they have after-tax costs of 14. % APR and 4. 8% APR respectively, which exceed the rate earned on savings. The home equity loan should not be repaid, as its EAR = (1 + 5%/12)12 – 1 = 5. 12%, for an after-tax rate of only 5. 125(1 – . 35) = 3. 33%, which is below the rate earned on savings. 5-38. Suppose you have outstanding debt with an 8% interest rate that can be repaid anytime, and the interest rate on U. S. Treasuries is only 5%. You plan to repay your debt using any cash that you don’t invest elsewhere. Until your debt is repaid, what cost of capital should you use when evaluating a new risk-free investment opportunity? Why?The appropriate cost of capital for a new risk-free investment is 8%, since you could earn 8% without risk by paying off your existing loan and avoiding interest charges. 5-39. In the summer of 2008, at Heathrow Airport in London, Bestofthebest (BB), a private company, offered a lottery to win a Ferrari or 90,000 British pounds, equivalent at the time to about $180,000. Both the Ferrari and the money, in 100 pound notes, were on display. If the U. K. interest rate was 5% per year, and the dollar interest rate was 2% per year (EARs), how much did it cost the company in dollars each month to keep the cash on display?That is, what was the opportunity cost of keeping it on display rather than in a bank account? (Ignore taxes. ) Because the prize is in pounds, we should use the pound interest rate (comparable risk). (1. 05)(1/12) – 1 = . 4074%. 0. 4074% x 90k = 366. 7 pounds per month, or $733 per month at the current exchange rate. 5-40. You firm is considering the purchase of a new office phone system. You can either pay $32,000 now, or $1000 per month for 36 months. a. Suppose your firm currently borrows at a rate of 6% per year (APR with monthly compounding).Which payment plan is more attractive? b. Suppose your firm currently borrows at a rate of 18% per year (APR with monthly compounding). Which payment plan would be more attractive in this case? a. The payments are as risky as the firm’s other debt. So opportunity cost = debt rate. PV(36 month annuity of 1000 at 6%/12 per month) = $32,871. So pay cash. b. PV(annuity at 18%/12 per mo) = $27,661. So pay over time. ———————– 47 –500 0 2 –500 1 –500 48 –500 47 –500 0 19,992. 39 2 –500 1 –500 48 –(500 – X) N -750 0 20,092. 39 2 -750 1 -750 [pic]

The Causes and Effects of Internet Addiction

What is internet addiction? * Internet Addiction: Destroying your mind. â€Å"Your Brain on Clicks† There are a lot of people today in the world, especially in the Philippines who may have been addicted to different kinds of vices. One of these may probably be called â€Å"internet addiction. † Men and women, even youngsters these days are being pulled out from their spiritual lives by the wickedness of this world and even, I myself have been greatly affected by this. Satan is attacking us slowly, that we didn’t notice what our lives may be doing, because we may usually think it is normal to be addicted to internet, but we know that God hates it. He is a jealous God. God has been hurt in many ways because when He calls us, we can’t hear because our eyes, and ears are focused on the world. In a world of rapidly advancing technology, it is hard to ignore that internet is becoming more and more centric to our lives, worldwide. Yet the convenience the electronic age provides come with a price. The ugly truth is that the internet is as addictive as it is useful. Internet addiction can destroy us in every way, and we find ourselves invariably and unwittingly chained by the shackles of the addictive elements of the internet. The early internet was used by computer experts, engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used it, whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system. Most people today rely on the web for almost anything. With just one click, one can find information within seconds when it would have taken hours, even days, poring through encyclopedias in the past. Social networking sites have made the world smaller, as we find friends we have lost touch with since childhood years. The Internet also provides online conveniences such as shopping, banking and paying bills. Indeed, it has also changed the way we live. However, technology comes with a price. With the advent of the internet came the proliferation of identity theft and  pornography and, lately, the emergence of also a new  disorder called  Internet Addiction Disorder (IAD), which has now become a subject of research among scientists and psychologists. Similar to gambling in our surroundings, internet addiction is also included in the  process type of addiction,  which is an addiction to certain mood behaviors. People who are internet addicts develop a compulsive habit to surf the net, join chat rooms, and nurture virtual characters by playing online games. People who are caught up in the net due to various reasons, are mostly for relaxation, work, or both. When their balance gets lost, more of their time becomes devoted in the virtual world, and then this is where the internet starts to become addictive. When a person is dysfunctioned, he or she jeopardizes or compromises his work, school, family, and relationships because of spending too much time on the net. If we lose track of time or if we neglect our responsibilities we are showing signs of a person who is extremely absorbed in the Internet. If we continue getting addicted to internet, we might risk our personal health because of excessive use. We might develop unhealthy habits like skipping our meals just to stay online, because we cannot stop the urge of using the net. Most people nowadays in our society are so addicted that whenever they cannot connect online, it brings them panic attacks or other disorders, feeling helpless and irritable. The Bible even tells us not to love the world or things in the world. Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh and the desires of the eyes and pride in possessions—is not from the Father but is from the world. And the world is passing away along with its desires, but whoever does the will of God abides fore ver. † (1 John 2:15-17) Because of this, as Christians and children of God, we must manage or limit internet use and control the urge to stay online longer than intended, before it becomes a serious problem for us. Recognizing this signs will help computer addicts confront and deal with their addiction and if it still goes on a person should consider getting support from friends and loved ones or seeking professional help if they suspect that they are slowly becoming addicted to the net. * What are the main causes of internet addiction? A real addiction negatively affects home life, interpersonal relationships, work, and emotional health. Often an addiction will negatively impact a person's physical health as well. * A large preoccupation with being online. Often an individual will think a lot about their last session online, and be excited about the next time they can access the Web. * An individual needs to use the Internet more frequently to get satisfaction from the activity. * Feeling bored, upset, restless, moody, depressed or anxiety-ridden when they can't be online. * Becoming angry when someone needs the computer or refusing to share time – most common in households where there are shared computers. * Forgets all about time when online. * Can't stop getting online, no matter how hard they try. * Compulsive lying  to friends and family about time spent online. Puts a job, relationship, or other responsibility at risk in order to continue to spend time online. For example, a person may cancel a date, miss a family dinner, or forget a work meeting because of their computer time. * Uses the Internet to escape frequently. In some cases the Internet may be the only activity that calms an addicted and agitated person down. * When online, or after an online session a person may feel a sense of  manic depression, guilt, anxiety, or hopelessness. * Social Causes * Some people become addicted to the Internet because of the social connections they make online. Some online relationship activity can be useful and healthy, and many people utilize forums for advice or chats for relaxation, but when a person has many close online friends and no one to count on in the real world, problems can develop. * An Internet addicted individual though, will develop highly emotional attachments to online pals or even online dates. Online relationships are attractive to some because it can feel less risky than meeting live people in person. Online friends allow people to escape their real lives and possibly fulfill their needs for emotional contacts that they don't get in real life. Some who are addicted to online relationships may even create pretend personalities or personas of themselves. This is actually a dangerous practice because often the people who create these fake lives are already low on self-esteem or desperately seeking the approval of others. Instead of seeking real help, say from a counselor, these individuals just re-make themselves online, while changing nothing about their real offline lives. This can lead to increased symptoms of depression and feelings of inadequacy. * Personality Trait Causes One  interesting paper  on Internet addiction notes that some people may be predisposed to online addictions; much like one can be predisposed to an alcohol addiction. What the paper points out is that someone with the right mix of an addictive personality, life stressors, and poor emotional health could get addicted if the Internet happens to also fall into their life during this time. * Along with the previous example are people who may become addicted because the internet reinforces a positive feeling. For example, a wife not getting her emotional needs met by her husband, may hop online and find friendly sites and people willing to talk. Each time she has an issue with her husband there are positives to getting online. This reinforces the hold the Internet can have on someone. The Effects of Internet Addiction With most teens and adolescents, there is a thin line between casual Internet use and addiction. The Internet has become a portal to knowledge and digital adventure for many, but some parents fear the negative effects of the unlimited access to all forms of content. Parents specifically take issue with the easy access their children have to explicit material, and the compulsive behavior that can stem from it. Here are the facts on Internet addiction and its effects. Read more:  The Effects of Internet Addiction | eHow. com  http://www. ehow. com/about_5247242_effects-internet-addiction. html#ixzz1gVsf1UIn Definition * According to Helpguide. org, Internet addiction can be defined as compulsive use that interferes with the natural flow of one's daily life, relationships or work. The organization also notes that Internet addiction is not yet formally identified as a psychological disorder. The concept of Internet addiction has gained popularity due to prevailing evidence that shows compulsive use can have a detrimental effect on the lifestyle and health of the individuals who are connected to it. Signs of Addiction * People who have Internet addiction tend to have mixed feelings of both joy and guilt while on the computer. They generally lose track of time and neglect responsibilities. They uncontrollably use the computer to relieve stress, cheer up or for sexual gratification. They feel anxious or irritable when away from the computer and are more likely to alienate themselves from family and friends, generally preferring to make their social connections with strangers online. Social Effect * Internet addiction can be a significant threat to one's health and social well-being in that it enforces antisocial behavior. The addiction can lead to the inability to communicate in the real world by depriving the addict of the daily practices involved with interpersonal communication. The act of using facial expressions or certain gestures to relay intended emotion or emphasize meaning decline as the addict substitutes keystrokes resembling smiley faces, or avatars. Socially, subjects become more inclined to develop personality disorders in which they identify more with their Internet representation than their real-life persona. Ultimately, an addiction to the Internet can cripple one's ability to maintain a healthy social life. Sexual Effect * There is a popular belief among promoters of Internet censorship that overexposure to the type of explicit material available online can lead to a deluded view of real-life sexual interaction and to sex addiction. Helpguide. org defines sex addiction as compulsive sexual behavior that creates negative legal, emotional, career or physical consequences. This behavior is considered a common psychological disorder stemming from Internet addiction. Addiction Candidates * People who are most susceptible to Internet addiction are teenagers, people who already have anxiety attacks or issues with anxiety, those who have undergone recent trauma that has made them home-bound and less active, people with prior addictions and those with a lack of support from their peers or family. People coping with depression are the biggest candidates to find solace in excessive computer and Internet use.

Neighborhood Article Summary Essay Example

Neighborhood Article Summary Essay Example Neighborhood Article Summary Essay Neighborhood Article Summary Essay Neighborhood Article Summary Name: Institution: Instructor: Course: Date: Neighborhood Article Summary ED Sees Critical Capacities Unsafe conditions were cited in the Neighborhood Hospital. Cases of over staffing were reported . The overstaffing has led to hazardous conditions that interfere with the safety of the staffers. The health facility is flooded with patients suffering from ailments that can easily be treated at home. However, because of a dearth in alternative health care compels them to seek medical attention in the center. According to Dr. Gordon, it is evident that the region lacks adequate health facilities to carter for the destitute and low-income members of the society (Johnson, 2012). Dr. Gordon suggested that there was an urgent need to create awareness among the members of the society concerning symptoms and treatment of common ailments and injuries. He argued that majority of the patients who visit the health institutions have conditions that could receive treatment at home. An increase in the capacity of hospitals has compelled the patients to visit the health institution for minor injuries and ailments. The patients were forced to waist for more than six hours to receive medical attention (Johnson, 2012). Public Health Issues In the article, Dr. Gordon addresses a number of public health concerns. These concerns are accessibility to effective health care, mass awareness on common health ailments, overstaffing in health institutions and hazardous working conditions for health workers. These issues were represented in the various situations that surrounded the Neighborhood Hospital. These issues are of public concern because they affect the well-being of the members of the society. One concern that Dr. Gordon raises is that there is a dearth of adequate medical facilities to carter for the population of the region. The doctor elaborates further that this lack of adequate medical facilities is detrimental to the treatment of the less privileged members of the society. The government was charged with mandate of providing health care to its population. The human labor is the most important resource of a nation, and it is the government’s obligation to subsidies costs of health care. The less privileged members of the society should receive attention because their social and economic status creates inequity in their resource accessibility. The masses should receive education on the general illnesses and injuries that occur frequently. This awareness will help members of the community not only to avoid the common illness and but to also treat and manage them in case of their occurrence. The Neighborhood Hospital is experiencing an influx of patients because of their inability to treat and manage common ailments. Educating the masses will help to cut down on the costs of treating common illnesses. Creation of awareness will also allow the staff at the medical centers to focus on the urgent cases that require immediate medical attention. Dr. Gordon reported that the staff at Neighborhood Hospital was more than the required number and apart from this, the staff received exposure to hazardous working conditions. It is the responsibility of a company’s management to ensure that its employees work in favorable conditions. The health of the employees should be a priority of the employers. Exposure of the employees to conditions that put their health at risk will subsequently affect their input in the workplace. This will be detrimental to the health care that the patients receive at the health centers. Over staffing at the health facility worsens the working conditions. The result is overcrowding and sharing of limited resources. This will impede the performance of the health care givers. Smoking Breaks a Thing Of The Past The breaks that many companies and social institutions are giving employees are slowly fading away. This is because of the controversies that arose concerning the need for smokers to receive breaks. Smoking is not a disability that requires special attention and therefore that rationality behind the breaks was lost. The breaks taken by the employees can be legally regulated by the employer. This implies that the idea of employees ding away with the smoking breaks is quite feasible. The strings attached to the breaks given to the employee are dictated by the employer (Johnson, 2012). Public Health Issue The public health issue that has been addressed is that of smoking cessation. The effects of tobacco on the public are the driving force behind these efforts. Antismoking programs were extended to the office set up. The management of companies is being encouraged to adopt systems that discourage smoking during the work routine. The government has also been receiving pressure to allocate funds of tobacco cessation. This was because of the rise in tobacco related illness that was burdening the country’s economy. These efforts will aid in the protection of passive smokers and the active smokers themselves. Second hand smoking is known to be the cause of many premature deaths and illnesses.

Overview of Crime Mapping and Analysis

Overview of Crime Mapping and Analysis Geography is a field that is ever-changing and ever-growing. One of its newer sub-disciplines is crime mapping, which uses geographic technologies in order to aid in crime analysis. In an interview with Steven R. Hick, a leading geographer in the field of crime mapping, he gave a thorough overview of the state of the field and what’s to come. What Is Crime Mapping? Crime mapping identifies not only where the actual crime took place, but also looks at where the perpetrator â€Å"lives, works, and plays† as well as where the victim â€Å"lives, works, and plays.† Crime analysis has identified that the majority of criminals tend to commit crimes within their comfort zones, and crime mapping is what allows police and investigators to see where that comfort zone might be. Predictive Policing Through Crime Mapping The use of predictive policing is a much more cost-effective approach to policing than past policies. This is because predictive policing not only looks at where a crime is likely to occur but also when the crime is likely to occur. These patterns can help police identify what time of day it is necessary to flood an area with officers, rather than flooding the area twenty-four hours a day. Types of Crime Analysis Tactical Crime Analysis: This type of crime analysis looks at the short-term in order to stop what is currently taking place, for example, a crime spree. It is used to identify one perpetrator with many targets or one target with many perpetrators and provide an immediate response. Strategic Crime Analysis: This type of crime analysis looks at the long-term and on-going issues. Its focus is often on identifying areas with high crime rates and problem-solving ways to decrease the overall crime rates. Administrative Crime Analysis This type of crime analysis looks at the administration and deployment of police and resources and asks the question, â€Å"Are there enough police officers at the right time and place?† and then works to make the answer, â€Å"Yes.† Crime Data Sources Crime Mapping Software ArcGIS MapInfo Crime Prevention Through Environmental Design CPTED Careers in Crime Mapping There are classes available in crime mapping; Hick is one professional who has been teaching these classes for several years. There are also conferences available for both professionals and beginners in the field. Additional Resources on Crime Mapping International Association of Crime Analysts The National Institute of Justice (NIJ) is a research agency of the United States Department of Justice that works to develop innovative solutions to crime.

Explaining a recent innovation in your area of interest or expertise Research Paper

Explaining a recent innovation in your area of interest or expertise - Research Paper Example This is a process that has taken to task doctors and scientists worldwide. One of the major setbacks to this work was inadequate finances. Though this is and has been a global problem, states were not able to come together to pool resources so as to support the noble work that the scientists set out to do. It turned out that only few countries provided the financial support to this project, while others showed no interests in the on-going work, yet they too are affected by the virus. The accomplishment was nonetheless realized thanks to the support of the non-governmental organizations and other well-wishers (Grady, 1995). Another great challenge is the fact that the HIV virus replicates very fast, and once it attacks a CD4+ T cell, it quickly makes very many copies of itself. These copies infect other immune cells. Since it makes many copies of itself, it overwhelms the body’s immunity hence weakening the body. This is worsened by the fact that as the replication takes place, there is DNA sequence change that results into different strands of the virus. The vaccine developed should be able to help prevent all these strands. Unlike many other viruses that attack the human body, the primary target of the HIV virus is the immune system, particularly the CD4+ cells. The virus destroys these cells hence making it difficult for the body to protect itself from other infections, even subsequent HIV infections. The vaccine developed therefore has to work to strengthen the system so that the invading virus does not weaken the body, but is able to prepare it to fight off the virus, at the same time leaving the body strong. There are already in existence big companies that manufacture anti-retroviral drugs (ARVs), the drugs currently used to contain the deadly virus. These companies are already making billions in this business and would therefore want to keep making money. An attempt to come up with vaccines is a threat to their business
