African Americans health disparities Essay

In 2011, the diagnosis rate for HIV cases in the United States was 15. 8 per 100,000 population and 60. 4 among Blacks. Of 197,090 diagnoses of HIV-infection from 2008- 2011, Blacks/African Americans accounted for: ?47% OF THE TOTAL ?64% OF WOMEN ?66% OF INFECTIONS ATTRIBUTED TO HETEROSEXUAL CONTACT ?67% OF CHILDREN, AGES < 13 In 2010, the death rate for blacks was higher (25. 0 per 100,000) compared with any other racial ethnicity group (3. 0 whites). Blacks represented 49% of all deaths with HIV in 2010. A recent study showed that blacks diagnosed with HIV are less likely than other groups to be linked to care, retained in care, receive antiretroviral treatment and achieve adequate viral suppression. African American Males African American men accounted for 42% of HIV cases diagnosed among men in 2011. A majority (72%) of African American men with HIV contracted the disease by male to male contact while 19% contracted HIV through heterosexual exposure. African American Females Among African American women, high risk heterosexual contact was the most frequently cited mode of transmission, accounting for 89% of cases diagnosed in 2011.

The rate of gonorrhea among blacks in 2010 was 432. 5 cases per 100,000 population, which was 18. 7 times the rate among whites (23. 1). This disparity has changed little in recent years. This disparity was larger for black men (22.2 times) than for black women (16. 2 times). Chlamydia In 2010, the overall rate among blacks in the United States was 1,167. 5 cases per 100,000, a 4. 0% increase from the 2009 rate of 1,122. 2 cases per 100,000. The rate of chlamydia among black women was over seven times the rate among white women (1,536. 5 and 205. 1 per 100,000 women, respectively). The chlamydia rate among black men was almost 11 times the rate among white men (761. 8 and 69. 9 cases per 100,000 men, respectively). Syphilis.

Diabetes and Cardiovascular Disease in New Zealand

Cardiovascular disease (CVD) and diabetes are major health issues for Maori, Pacific and south Asian people. The impacts of these diseases are increasing hospital admissions and readmissions hence increasing with an aging population. (Kaitiaki Nursing, New Zealand, 2013, pg. 20). Diabetes mellitus has been well pronounced as a cardiovascular risk factor in New Zealand and people with diabetes are 2-4 times more likely to suffer from CVD hence is a leading cause of death in diabetic patients (ministry of health, 2011, pg. 2). Diabetes mellitus type 2 is a preventable and reversible condition giving rise to a range of serious complications associated with nerve and blood vessel damage that bring on blindness, limb amputations, kidney disease, and increased risk of infection (Powers, 2005). According to Diabetes New Zealand (2008), people with diabetes increases the risk of developing narrowed, thickened or completely occluded arteries (atherosclerosis) due to an elevated blood sugar level. Insulin resistant diabetes (type 2) or a complete absence of insulin (type 1) increases serum lipid levels as cells try to break down fats and protein to form energy. Lipids are released as the bio-product which then travels in blood increasing the risk for occlusion in blood vessels. Hyperglycaemia, insulin resistance and altered serum lipid levels are responsible for formation of coronary plaque and blood clot in vessels. This leads to health issues such as ischaemic heart disease, stroke, hypertension myocardial infarction etc. (Lewis, 2012, 1388-1389). In New Zealand Maori, Pacific Islanders and South Asians are at a higher risk of developing diabetes, increasing chances of dying of cardiovascular diseases. Modifiable factors such as nutrition, physical inactivity, smoking, alcohol consumption and body size influence the risk of getting affected by diabetes and CVD. According to Ministry of Health (2008) diabetes occurs earlier in Pacific and Maori peoples, about 10 years before Europeans which contributes to an increased risk of chronic health conditions and mortality rate. It is appraised that due to demographic trends and projected growth in obesity, the number of diabetes cases will increase and the increase will be greater within the Maori, Pacific, and south Asian populations (Ministry of Health, 2008d). 5% of adults in New Zealand meet the criteria for obesity due to lifestyle, unhealthy nutrition and increased physical inactivity (eg. 42% of Maori and 63. 7% of Pacific peoples meet the criteria for obesity). The New Zealand Medical Journal, 2006 states that Asian new Zealanders especially Indians show a very high percentage of diabetes and CVD which is similar to Maori people (A meratunga, Rasanathan, Tse, 2006). According to the Ministry of Health (2009), more Maori, South Asian and pacific people died from the year 1987- 2006 when compared to non-Maori. Obesity is primarily caused by poor nutrition and sedentary lifestyles (Ministry of Health, 2008e). The New Zealand sport and physical activity surveys (conducted in 1997/98, 1998/99, and 2000/01) by Sport and Recreation New Zealand (SPARC) found that Pacific, Maori and south Asian children had higher levels of inactivity than other groups. Additionally, a healthy diet is a key determinant of health outcomes and is particularly important for the growth and development. With regards to ministry of health (2003), Maori, south Asian and more of pacific people in new Zealand tend to eat more unhealthy food as it came cheaper and children skipped breakfast due to lack of parental supervision. Smoking is seen to be another lifestyle adaptation amongst the New Zealand community and the leading risk factor for many forms of cardiovascular disease and diabetes. More Maori and Pacific individuals’ smoke (45 percent and 31 percent, respectively) compared with the total New Zealand population (20. percent) (Ministry of Health, 2008k). The Youth 2007 Survey found that twice as many Pacific students are regular smokers when compared to European students. Furthermore, level of economic resources available to the pacific and south asian people is another important social determinants of health. Asians generally do not show increased health issues statistically but south Asian particularly Indians are at a very high risk. Despite high levels of disease, Indi an New Zealanders are rarely presumed as a priority group in current diabetes strategies. For example, â€Å"Let’s Beat Diabetes Strategy† by Counties Manukau District Health Board fails to mention Indian people specifically but considers the general Asian population. Another possibility for the disproportionate effect on south Asian and pacific people could be higher levels of unemployment and lower income as a group (ministry of health, 2006). This is partly due to a lack of effective settlement strategies for migrant Asians and pacific people to New Zealand. Lack of employment and difficulties settling into the host community are associated with negative health effects and reduced accessibility to health care facility (Ameratunga, Rasanathan, Tse, 2006). The risk associated with diabetes and cardiovascular disease can be reduced and these conditions only respond well if managed with appropriate care. Evidence proposes that many Pacific individuals are often ignorant of the government services offered to them (Koloto & Associates Ltd, 2007; Paterson, 2004). This demonstrates ineffective communication by health information services and providers. Primarily, nurses need to build a trusting therapeutic relationship via therapeutic communication techniques such as active listening, paraphrasing etc. It facilitates client autonomy, creates a non-judgmental environment and provides the professional with the holistic view of the client for better management. With reference to the case study by Counties Manukau DHB (Ministry of Health, 2011, pg. 6) the diabetic patient (Mr Cooper) found it difficult to follow instructions given by the doctor therefore his diabetes nurse helped him with all the information he needed. He verbalised ‘I learned a lot from the nurse. I learned how serious diabetes is and how it is not going to go away, but also how it is possible to live a normal life if you manage what you eat, etc. ’ This specifies that nurses are the closest health professionals who spends the most time with patients and so can work with the patients in partnership. In order to manage diabetes and CVD effectively (Ministry of health, 2011, pg. 2), it is very important for nurses to educate their patients about the risk factors and what needs to be done to improve early detection and management of diabetes and CVD. Adherence to therapies anticipated to control risk factors such as lipid levels or blood pressure for patients with type 2 diabetes is seen to reduce major cardiovascular complications and increase survival (Barrat, Butow, Caldwell, Davey & Travena, 2006,pg. 13-23) . One probable way to improve patients’ metabolic control is to help them understand the risks of the disease and the likely benefits of available therapy options. Research has shown that information on the potential benefits of improving modifiable risk factors may assist both health professionals and patients in making treatment decision. This may increase patients’ willingness to accept management strategies recommended by their doctors and nurses. In fact, nurses as health educators can use diverse formats (e. g. decision aids, brochures, verbal advice) increasing patients’ knowledge and understanding (Barrat, Butow, Caldwell, Davey & Travena, 2006, 13-23). However, as suggested by the New Zealand Guidelines Group (2003) nurses and other health professionals need to make use of an evidence-based practice in the management of diabetes as well as assessing the risk of cardiovascular disease. However, despite CVD and diabetes assessments being developed, uptake is often low. A possible reason for this is that many Pacific and Maori people do not prioritise health and generally would not seek any help unless they have physical symptoms such as pain or discomfort. With reference to nursing council of New Zealand competency 3. 2 forming partnership with the client and raising awareness for example informing and referring Maori patients about management programmes such as â€Å"Get Checked† which provides free annual check-up for people with diabetes. This programme focuses on physical health, lifestyle and disease management. According to Robson and Harris (2007), Maori enrolment in get checked programme in 2006 was lower than non-Maori. This is a clear indicator of moari people’s lack of knowledge about services being provided. However, nurses as professionals should practice nursing in a very culturally safe manner by acknowledging patients values beliefs and attitude towards health care. For example Maori people believe in â€Å"kanohi te kanohi† meaning face to face communication therefore nurses need to have more in person communication (Reid & Robson, 2007). Nurses should also inform clients about initiatives for example â€Å"one heart many lives† which allows Maori and pacific men to get their hearts checked, improve awareness of heart disease and lifestyle habits. Furthermore, CVD assessment allows an early detection of the number of people being at risk of cardiovascular disease. The sooner it is detected the earlier these issues can be controlled as stated in the document published by the ministry of health (2011). The practice nurse is the key person to co-ordinate care for instance after reviewing a diabetic patient he or she may decide to refer the patient to the dietician. This way the patient is given an efficient holistic care with appropriate information (Kaitiaki Nursing, New Zealand, 2013, pg. 27) Nurses need to collaborate with the clients, agree on patient centered health goals such as promotion, prevention and early management of diabetes and cardiovascular disease by setting achievable and measurable goals. For example, ministry of health national health information Board launched a Shared Care Plan in 2011 which was in response to increasing number of deaths due to poor management of chronic illnesses. This programme aims to improve care of patients by increasing patient involvement (Kaitiaki Nursing, New Zealand, march, 2013, pg. 26). The New Zealand Cardiovascular Risk Chart shows that diabetic people who smoke are at much higher risk of developing CVD when compared to a non-diabetic and non-smoker (New Zealand guidelines Group, 2009). According to Solberg (2006) there is evidence that professional advice given by the health care provider helps patients to quit smoking. Nurses can effectively use the ABC tool provided by the ministry of health (2007) to help patients to quit smoking. Nurses need to inform clients about the advantages of being a non-smoker financially and health wise and provide alternative as to how nicotine replacement therapy helps minimise the urge to smoke. A practice nurse is responsible for most of patients’ assessments and health education, therefore nurses need to understand the standpoint of her patient and what does being healthy means to them. Establishing relationships and understanding their culture and customs. For example food plays a big role in pacific, Maori and south Asian culture. Family involvement in care plan is very important in shaping attitudes and activities as family plays an important role in their lives also explaining the effects of unhealthy and sedentary lifestyle. Nurses should use plain language and ensure the patient and their family understands what changes they need to make and why they need to make them. They should also make sure that the patient and family are fully informed about the care plan and any procedures being done to maximise care (Blakely, 2007). In conclusion it can be said that patients are fully dependant on nurses with regards to any health issues they have. Nurses are the first form of contact to patient in primary and secondary care setting who provides them with accurate information. It is very important for nurses to be aware of the fact that Maori, Pacific and South Asian New Zealander are more proned to diabetes and CVD therefore more emphasis should be given to them. During the assessment nurses should always consider patients socio-economic inequality, access to and quality of health care, and health risk factors such as tobacco, diet, and other lifestyle factors.

Define and recognize in a problem statement the economy symbols P, F, A, n, and i. 1. 6 Define cash flow, state what is meant by end-of-period convention, and construct a cash-flow diagram, given a statement describing the amount and times of the cash flows. Study Guide 1. 1 Basic Terminology Before we begin to develop the terminology and fundamental concepts upon which engineering economy is based, it would be appropriate to define what is meant by engineering economy . In the simplest terms, engineering economy is a collection of mathematical techniques which simplify economic comparisons. With these techniques, a rational, meaningful approach to evaluating the economic aspects of different methods of accomplishing a given objective can be developed. Engineering economy is, therefore, a decision assistance tool by which one method will be chosen as the most economical one. In order for you to be able to apply the techniques, however, it is necessary for you to understand the basic terminology and fundamental concepts that form the foundation for engineering-economy studies. Some of these terms and concepts are described below. An alternative is a stand-alone solution for a give situation. We are faced with alternatives in virtually everything we do, from selecting the method of transportation we use to get to work every day to deciding between buying a house or renting one. Similarly, in engineering practice, there are always seveffl ways of accomplishing a given task, and it is necessary to be able to compare them in a rational manner so that the most economical alternative can be selected. The alternatives in engineering considerations usually involve such items as purchase cost (first cost), the anticipated life of the asset, the yearly costs of maintaining the asset (annual maintenance and operating cost), the anticipated resale value (salvage value), and the interest rate (rate of return). After the facts and all the relevant estimates have been collected, an engineering-economy analysis can be conducted to determine which is best from an economic point of view. However, it should be pointed out that the procedures developed in this book will enable you to make accurate economic decisions only about those alternatives which have been recognized as alternatives; these procedures will not help you identify what the alternatives are. That is, if alternatives ,4, B, C, D, and E have been identified as the only possible methods to solve a Particular problem when method F, which was never recognized as an alternative, is really the most attractive method, the wrong decision is certain to be made because alternative F could never be chosen, no matter what analytical techniques are used. Thus, the importance of alternative identification in the decision-making process cannot be overemphasized, because it is only when this aspect of the process has been thoroughly completed that the analysis techniques presented in this book can be of greatest value. In order to be able to compare different methods for accomplishing a given objective, it is necessary to have an evaluation criterion that can be used as a basis Terminology and Cash-Flow Diagrams 5 for judging the alternatives. That is, the evaluation criterion is that which is used to answer the question â€Å"How will I know which one is best? Whether we are aware of it or not, this question is asked of us many times each day. For example, when we drive to work, we subconsciously think that we are taking the â€Å"best† route. But how did we define best? Was the best route the safest, shortest, fastest, cheapest, most scenic, or what? Obviously, depending upon which criterion is used to identify the best, a dif ferent route might be selected each time! (Many arguments could have been avoided if the decision makers had simply stated the criteria they were using in determining the best). In economic analysis, dollars are generally used as the basis for comparison. Thus, when there are several ways of accomplishing a given objective, the method that has the lowest overall cost is usually selected. However, in most cases the alternatives involve intangible factors, such as the effect of a process change on employee morale, which cannot readily be expressed in terms of dollars. When the alternatives available have approximately the same equivalent cost, the nonquantifiable, or intangible, factors may be used as the basis for selecting the best alternative, For items of an alternative which can be quantified in terms of dollars, it is important to recognize the concept of the time value of money. It is often said that money makes money. The statement is indeed true, for if we elect to invest money today (for example, in a bank or savings and loan association), by tomorrow we will have accumulated more money than we had originally invested. This change in the amount of money over a given time period is called the time value of money; it is the most important concept in engineering economy. You should also realize that if a person or company finds it necessary to borrow money today, by tomorrow more money than the original loan will be owed. This fact is also explained by the time value of money. The manifestation of the time value of money is termed interest, which is a measure of the increase between the original sum borrowed or invested and the final amount owed or accrued. Thus, if you invested money at some time in the past, the interest would be Interest = total amount accumulated – original investment (1. 1) On the other hand, if you borrowed would be Interest money at some time in the past, the interest (1. 2) = present amount owed – original loan In either case, there is an increase in the amount of money that was originally invested or borrowed, and the increase over the original amount is the interest. The original investment or loan is referred to as principal. Probs. 1. 1 to 1. 4 1. 2 Interest Calculations When interest is expressed as a percentage of the original amount per unit time, the result is an interest rate. This rate is calculated as follows: . Percent interest rate = interest accrued per unit time 00% .. I x 1 0 origma amount (1. 3) 6 Level One By far the most common time period used for expressing interest rates is 1 year. However, since interest rates are often expressed over periods of time shorter than 1 year (i. e. 1% per month), the time unit used in expressing an interest rate must also be identified and is termed an interest period. The following two examples illustrate the computation of interest rate. Example 1. 1 The Get-Rich-Quick (GRQ) Company invested $100,000 on May 1 and withdrew a total of $106,000 exactly one year later. Compute (a) the interest gained from the original investment and (b) the interest rate from the investment. Solution (a) Using Eq. ( 1. 1), Interest = 106,000 – 100,000 = $6000 (b) Equation (1. 3) is used to obtain Percent interest rate = 6000 per year 100,000 x 100% = 6% per year Comment For borrowed money, computations are similar to those shown above except that interest is computed by Eq. (1. 2). For example, if GRQ borrowed $100,000 now and repaid $110,000 in 1 year, using Eq. (1. 2) we find that interest is $10,000, and the interest rate from Eq. (1. 3) is 10% per year. Example 1. 2 Joe Bilder plans to borrow $20,000 for 1 year at 15% interest. Compute (a) the interest and (b) the total amount due after 1 year. Solution (a) Equation (1. 3) may be solved for the interest accrued to obtain Interest = 20,000(0. 15) = $3000 (b) Total amount due is the sum of principal and interest or Total due Comment = 0,000 + 3000 = $23,000 Note that in part (b) above, the total amount due may also be computed as Total due = principal(l + interest rate) = 20,000(1. 15) = $23,000 In each example the interest period was 1 year and the interest was calculated at the end of one period. When more than one yearly interest period is involved (for example, if we had wanted to know the amount of interest Joe Bilder would owe on Terminology and Cash-Flow Diagrams 7 the above loan after 3 years), it becomes necessary to determine whether the interest . payable on a simple or compound basis. The concepts of simple and compound interest are discussed in Sec. . 4. Additional Examples 1. 12 and 1. 13 Probs. 1. 5 to 1. 7 1. 3 Equivalence The time value of money and interest rate utilized together generate the concept of equivalence, which means that different sums of money at different times can be equal in economic value. For example, if the interest rate is 12% per year, $100 today (i. e. , at present) would be equivalent to $112 one year from today, since mount accrued = 100 =$112 Thus, if someone offered you a gift of $100 today or $112 one year from today, it would make no difference which offer you accepted, since in either case you would have $112 one year from today. The two sums of money are therefore equivalent to each other when the interest rate is 12% per year. At either a higher or a lower interest rate, however, $100 today is not equivalent to $112 one year from today. In addition to considering future equivalence, one can apply the same concepts for determining equivalence in previous years. Thus, $100 now would be equivalent to 100/1. 12 = $89. 29 one year ago if the interest rate is 12% per year. From these examples, it should be clear that $89. 29 last year, $100 now, and 112 one year from now are equivalent when the interest rate is 12% per year. The fact that these sums are equivalent can be established by computing the interest rate as follows: 112 100 = 1. 12, or 12% per year and 8~~~9 = 1. 12, or 12% per year The concept of equivalence can be further illustrated by considering different loan-repayment schemes. Each scheme represents repayment of a $5000 loan in 5 years at 15%-per-year interest. Table 1. 1 presents the details for the four repayment methods described below. (The methods for determining the amount of the payments are presented in Chaps. 2 and 3. ) †¢ Plan 1 a interest or principal is recovered until the fifth year. Interest accumulates each year on the total of principal and all accumulated interest. †¢ Plan 2 The accrued interest is paid each year and the principal is recovered at the end of 5 years. †¢ Plan 3 The accrued interest and 20% of the principal, that is, $1000, is paid each year. Since the remaining loan balance decreases each year, the accrued interest decreases each year. + 100(0. 12) = 100(1 + 0. 12) = 100(1. 12) 8 Level One Table 1. 1 Different repayment schedules of $5,000 at 15% for 5 years (1) End of year (2) = 0. 15(5) Interest for year (3) = (2) + (5) Total owed at end of year (4) Payment per plan (3) – (4) Balance after payment (5) Plan 1 0 1 2 3 4 5 Plan 2 0 1 2 3 4 5 Plan 3 0 1 2 3 4 5 Plan 4 0 1 2 3 4 5 $ 750. 00 862. 50 991. 88 1,140. 66 1,311. 76 5,750. 00 6,612. 50 7,604. 38 8,745. 04 10,056. 80 0 0 0 0 10,056. 80 $10,056. 80 $ $5,000. 00 5,750. 00 6,612. 50 7,604. 38 8,745. 04 0 $750. 00 750. 00 750. 00 750. 00 750. 00 $5,750. 00 5,750. 00 5,750. 00 5,750. 00 5,750. 00 $ 750. 00 750. 00 750. 00 750. 00 5,750. 00 $8,750. 00 $5,000. 00 5,000. 00 5,000. 00 5,000. 00 5,000. 00 0 $750. 00 600. 00 450. 00 300. 00 150. 00 $5,750. 00 4,600. 00 3,450. 00 2,300. 00 1,150. 00 $1,750. 00 1,600. 00 1,450. 0 1,300. 00 1,150. 00 $7,250. 00 5,000. 00 4,000. 00 3,000. 00 2,000. 00 1,000. 00 0 $750. 00 638. 76 510. 84 363. 73 194. 57 $5,750. 00 4,897. 18 3,916. 44 2,788. 59 1,491. 58 $1,491. 58 1,491. 58 1,491. 58 1,491. 58 1,491. 58 $7,457. 90 $5,000. 00 4,258. 42 3,405. 60 2,424. 86 1,297. 01 0 †¢ Plan 4 Equal payments are made each year with a portion going toward princi- pal recovery and the remainder covering the accrued interest. Since the loan balance decreases at a rate which is slower than in plan 3 because of the equal end-of-year payments, the interest decreases, but at a rate slower than in plan 3. te that the total amount repaid in each case would be different, even though each repayment scheme would require exactly 5 years to repay the loan. The difference in the total amounts repaid can of course be explained by the time value of money, since the amount of the payments is different for each plan. With respect to equivalence, the table shows that when the interest rate is 15% per year, $5000 at time 0 is equivalent to $10,056. 80 at the end of year 5 (plan 1), or $750 per year for 4 years and $5750 at the end of year 5 (plan 2), or the decreasing amounts shown in years 1 through 5 (plan 3), or $1,491. 8 per year for 5 years (plan 4). Using the formulas developed in Chaps. 2 and 3, we could easily show that if the payments in Terminology and Cash-Flow Diagrams 9 each plan (column 4) were reinvested at 15% per year when received, the total amount of money available at the end of year 5 would be $10,056. 80 from each repayment plan. Additional Examples 1. 14 and 1. 15 Probs. 1. 8 and 1. 9 1. 4 Simple and Compound Interest The concepts of interest and interest rate were introduced in Sees. 1. 1 and 1. 2 and ed in Sec. 1. 3 to calculate for one interest period past and future sums of money equivalent to a present sum (principal). When more than one interest period is involved, the terms simple and compound interest must be considered. Simple interest is calculated using the principal only, ignoring any interest that was accrued in preceding interest periods. The total interest can be computed using the relation Interest = (principal)(number of periods)(interest rate) = Pni (1. 4) Example 1. 3 If you borrow $1000 for 3 years at 14%-per-year simple interest, how much money will you owe at the end of 3 years? Solution The interest for each of the 3 years is = Interest per year 1000(0. 14) = $140 Total interest for 3 years from Eq. (1. 4) is Total interest = 1000(3)(0. 4)= $420 Finally, the amount due after 3 years is 1000 + 420 Comment = $1420 The $140 interest accrued in the first year and the $140 accrued in the second year did not earn interest. The interest due was calculated on the principal only. The results of this loan are tabulated in Table 1. 2. The end-of-year figure of zero represents th~ present, th at is, when the money is borrowed. Note that no payment is made by the borrower until the end of year 3. Thus, the amount owed each year increases uniformly by $140, since interest is figured only on the principal of $1000. Table 1. 2 Simple-interest (1) (2) computation (3) (4) (2) + (3) Amount owed (5) End of year 0 1 2 Amount borrowed $1,000 Interest Amount paid 3 $140 140 140 $1,140 1,280 1,420 $ 0 0 1,420 10 Level One In calculations of compound interest, the interest for an interest period is calculated on the principal plus the total amount of interest accumulated in previous periods. Thus, compound interest means â€Å"interest on top of interest† (i. e. , it reflects the effect of the time value of money on the interest too). Example 1. 4 If you borrow $1000 at 14%-per-year compound interest, instead of simple interest as in the preceding example, compute the total amount due after a 3-year period. Solution The interest and total amount due for each year is computed as follows: Interest, year 1 = 1000(0. 14) = $140 Total amount due after year 1 = 1000 + 140 = $1140 Interest, year 2 = 1140(0. 14) = $159. 60 Total amount due after year 2 = 1140 + 159. 60 = $1299. 60 Interest, year 3 = 1299. 60(0. 14)= $181. 94 Total amount due after year 3 = 1299. 60 + 181. 94 = $1481. 54 Comment The details are shown in Table 1. 3. The repayment scheme is the same as that for the simple-interest example; that is, no amount is repaid until the principal plus all interest is due at the end of year 3. The time value of money is especially recognized in compound interest. Thus, with compound interest, the original $1000 would accumulate an extra $1481. 54 – $1420 = $61. 54 compared with simple interest in the 3-year period. If $61. 54 does not seem like a significant difference, remember that the beginning amount here was only $1000. Make these same calculations for an initial amount of $10 million, and then look at the size of the difference! The power of compounding can further be illustrated through another interesting exercise called â€Å"Pay Now, Play Later†. It can be shown (by using the equations that will be developed in Chap. ) that at an interest rate of 12% per year, approximately $1,000,000 will be accumulated at the end of a 40-year time period by either of the Table 1. 3 Compound-interest (1) (2) computation (3) (4) = (2) + (3) (5) End of year 0 1 2 3 Amount borrowed $1,000 Interest Amount owed $1,140. 00 1,299. 60 1,481. 54 Amount paid $140. 00 159. 60 181. 94 $ 0 0 1,481. 54 Terminology and Cash-Flow Diagrams 11 – llowing investment schemes: †¢ Plan 1 Invest $2610 each year for the first 6 years and then nothing for the next 34 years, or †¢ Plan 2 Invest nothing for the first 6 years, and then $2600 each year for the next 34 years!! ‘ote that the total investment in plan 1 is $15,660 while the total required in plan _ to accumulate the same amount of money is nearly six times greater at $88,400. Both the power of compounding and the wisdom of planning for your retirement at he earliest possible time should be quite evident from this example. An interesting observation pertaining to compound-interest calculations in-olves the estimation of the length of time required for a single initial investment to double in value. The so-called rule of 72 can be used to estimate this time. The rule i based on the fact that the time required for an initial lump-sum investment to double in value when interest is compounded is approximately equal to 72 divided by the interest rate that applies. For example, at an interest rate of 5% per year, it would take approximately 14. 4 years (i. e. , 72/5 = 14. 4) for an initial sum of money to double in value. (The actual time required is 14. 3 years, as will be shown in Chap. 2. ) In Table 1. 4, the times estimated from the rule of 72 are compared to the actual times required for doubling at various interest rates and, as you can see, very good estimates are obtained. Conversely, the interest rate that would be required in order for money to double in a specified period of time could be estimated by dividing 72 by the specified time period. Thus, in order for money to double in a time period of 12 years, an interest rate of approximately 6% per year would be required (i. e. , 72/12 = 6). It should be obvious that for simple-interest situations, the â€Å"rule of 100† would apply, except that the answers obtained will always be exact. In Chap. 2, formulas are developed which simplify compound-interest calculations. The same concepts are involved when the interest period is less than a year. A discussion of this case is deferred until Chap. 3, however. Since real-world calculations almost always involve compound interest, the interest rates specified herein refer to compound interest rates unless specified otherwise.

It should be understood that a present sum P represents a single sum of money at some time prior to a future sum or uniform series amount and therefore does not necessarily have to be located at time t = O. Example 1. 11 shows a P value at a time other than t = O. The units of the symbols aid in clarifying their meaning. The present sum P and future sum F are expressed in dollars; A is referred to in dollars per interest period. It is important to note here that in order for a series to be represented by the symbol A, it must be uniform (i. e. the dollar value must be the same for each period) and the uniform dollar amounts must extend through consecutive interest periods. Both conditions must exist before the dollar value can be represented by A. Since n is commonly expressed in years or months, A is usually expressed in units of dollars per year or dollars per month, respectively. The compound-interest rate i is expressed in percent per interest period, for example, 5% per year. Ex cept where noted otherwise, this rate applies throughout the entire n years or n interest periods. The i value is often the minimum attractive rate of return (MARR). All engineering-economy problems must involve at least four of the symbols listed above, with at least three of the values known. The following four examples illustrate the use of the symbols. Example 1. 5. If you borrow $2000 now and must repay the loan plus interest at a rate of 12% per year in 5 years, what is the total amount you must pay? List the values of P, F, n, and i. Solution In this situation P and F, but not A, are involved, since all transactions are single payments. The values are as follows: P = $2000 Example 1. 6 i = 12% per year n = 5 years If you borrow $2000 now at 17% per year for 5 years and must repay the loan in equal yearly payments, what will you be required to pay? Determine the value of the symbols involved. Terminology and Cash-Flow Diagrams 13 ~- ution = S2000 = ? per year for 5 years = 17% per year = 5 years – ere is no F value involved. – 1 In both examples, the P value of $2000 is a receipt and F or A is a disbursement. equally correct to use these symbols in reverse roles, as in the examples below. Example 1. 7 T you deposit $500 into an account on May 1, 1988, which pays interest at 17% per year, hat annual amount can you withdraw for the following 10 years? List the symbol values. Solution p = $500 A =? per year i = 17% per year n= 10 years Comment The value for the $500 disbursement P and receipt A are given the same symbol names as before, but they are considered in a different context. Thus, a P value may be a receipt (Examples 1. 5 and 1. 6) or a disbursement (this example). Example 1. 8 If you deposit $100 into an account each year for 7 years at an interest rate of 16% per year, what single amount will you be able to withdraw after 7 years? Define the symbols and their roles. Solution In this example, the equal annual deposits are in a series A and the withdrawal is a future sum, or F value. There is no P value here. A = $100 per year for 7 years F =? i = 16% per year n = 7 years Additional Example 1. 17 Probs. 1. 27 to 1. 29 14 Level One 1. 6 Cash-Flow Diagrams Every person or company has cash receipts (income) and cash disbursements (costs) which occur over a particular time span. These receipts and disbursements in a given time interval are referred to as cash flow, with positive cash flows usually representing receipts and negative cash flows representing disbursements. At any point in time, the net cash flow would be represented as Net cash flow = receipts – disbursements (1. 5) Since cash flow normally takes place at frequent and varying time intervals within an interest period, a simplifying assumption is made that all cash flow occurs at the end of the interest period. This is known as the end-of-period convention. Thus, when several receipts and disbursements occur within a given interest period, the net cash flow is assumed to occur at the end of the interest period. However, it should be understood that although the dollar amounts of F or A are always considered to occur at the end of the interest period, this does not mean that the end of the period is December 31. In the situation of Example 1. 7, since investment took place on May 1, 1988, the withdrawals will take place on May 1, 1989 and each succeeding May 1 for 10 years (the last withdrawal will be on May 1, 1998, not 1999). Thus, end of the period means one time period from the date of the transaction (whether it be receipt or disbursement). In the next chapter you will learn how to determine the equivalent relations between P, F, and A values at different times. A cash-flow diagram is simply a graphical representation of cash flows drawn on a time scale. The diagram should represent the statement of the problem and should include what is given and what is to be found. That is, after the cash-flow diagram has been drawn, an outside observer should be able to work the problem by looking at only the diagram. Time is considered to be the present and time 1 is the end of time period 1. (We will assume that the periods are in years until Chap. . ) The time scale of Fig. 1. 1 is set up for 5 years. Since it is assumed that cash flows occur only at the end of the year, we will be concerned only with the times marked 0, 1, 2, †¦ , 5. The direction of the arrows on the cash-flow diagram is important to problem solution. Therefore, in this text, a vertical arrow pointing up will indicate a positive cash flow. Conversely, an a rrow pointing down will indicate a negative cash flow. The cash-flow diagram in Fig. 1. 2 illustrates a receipt (income) at the end of year 1 and a disbursement at the end of year 2. It is important that you thoroughly understand the meaning and construction of the cash-flow diagram, since it is a valuable tool in problem solution. The three examples below illustrate the construction of cash-flow diagrams.  ° Figure 1. 1 A typical cash-flow time scale. Year 1 Year 5 r=;:;; r+;:;.

Construct the cash-flow diagram for this case, assuming an interest rate of 12% per year. Solution Figure 1. 3 presents the cash-flow diagram. Comment While it is not necessary to use an exact scale on the cash-flow axes, you will probably avoid errors later on if you make a neat diagram. Note also that the present sum P is a receipt at year 0 and the future sum F is a disbursement at the end of year 5. Example 1. 10 If you start now and make five deposits of $1000 per year (A) in a 17%-per-year account, how much money will be accumulated (and can be withdrawn) immediately after you have made the last deposit? Construct the cash-flow diagram. Solution The cash flows are shown in Fig. 1. 4. Since you have decided to start now, the first deposit is at year 0 and the [lith Comment deposit and withdrawal occur at the end of year 4. Note that in this example, the amount accumulated after the fifth deposit is to be computed; thus, the future amount is represented by a question mark (i. e. , F = ? ) Figure 1. 3.

Assume that the interest rate is 151% per year. Construct the cash-flow diagram. Figure 1. 5 presents the cash flows, where P is to be found. Note that the diagram shows what was given and what is to be found and that a P value is not necessarily located at time t = O.

Solution a) Total amount accrued = original deposit + (original deposit)(interest rate). If X = original deposit, then 1000 = X + X(0. 5) = X(l + 0. 05) 1000 = 1. 05X 1000 X=-=952. 38 1. 05 Original deposit = $952. 38 (b) By using Eq.

Solution Let a = a = = total amount accrued and b = original deposit. Interest Since a Interest Interest b b + b (interest rate), interest can be expressed as + b (interest rate) b =b = b (interest rate) $100 = b(0. 06) b = 100 = $1666. 67 0. 06 Example 1. 5 Make the calculations necessary to show which of the statements below are true and which are false, if the interest rate is 5% per year: (a) $98 now is equivalent to $105. 60 one year from now. (b) $200 one year past is equivalent to $205 now. (c) $3000 now is equivalent to $3150 one year from now. (d) $3000 now is equivalent to $2887. 14 one year ago. (e) Interest accumulated in 1 year on an investment of $2000 is $100. Solution (a) Total amount accrued = 98(1. 05) = $102. 90 =P $105. 60; therefore false. Another way to solve this is as follows: Required investment = 105. 60/1. 05 = $100. 57 =P $9? Therefore false. b) Required investment = 205. 00/1. 05 = $195. 24 =p $200; therefore false. 18 Level One (e) Total amount accrued = 3000(1. 05) = $3150; therefore true.

Example 1. 16 Calculate the total amount due after 2 years if $2500 is borrowed now and the compoundinterest rate is 8% per year. Solution The results are presented in the table to obtain a total amount due of $2916.

How would the cash-flow diagram appear if i is 14! % per year? Solution The cash flows would appear as shown in Fig. 1. 7. Comment The first withdrawal (positive cash flow) occurs at the end of year 1, exactly one year after P is deposited. Figure 1. 7 Cash-flow diagram for two different A values, Example 1. 19.

Assume an interest rate of 12% per year. Solution Comment Figure 1. 8 presents the cash-flow diagram. The two $50 negative cash flows form a series of two equal end-of-year values. As long as the dollar values are equal and in two or more consecutive periods, they can be represented by A, regardless of where they begin or end. However, the $150 positive cash flow in 1999 is a single-occurrence value in the future and is therefore labeled an F value. It is possible, however, to view all of the individual cash flows as F values. The diagram could be drawn as shown in Fig. . 9. In general, however, if two or more equal end-of-period amounts occur consecutively, by the definition in Sec. 105 they should be labeled A values because, as is described in Chap. 2, the use of A values when possible simplifies calculations considerably. Thus, the interpretation pictured by the diagram of Fig. 1. 9 is discouraged and will not generally be used further in this text. p=? j = 12% per year F. = $150 1. 9 A cash flow for Example 1. 20 considering all values as future sums.

Interview with leaders or managers in any organization Essay

Interview with leaders or managers in any organization - Essay Example As a unit manager, she reports directly to the department manager of nursing. Her responsibilities include planning, organizing, directing and controlling all aspects of operations pertaining to the two units: cardiovascular and telemetry. Aside from the nurse managers who are directly involved in governing nurses for patient care and for the delivery of health care services, as unit manager, she performs all responsibilities involving administration and governance of the units. These responsibilities include performance appraisals and evaluation; scheduling of vacation leaves and monitoring of sick leaves; monitoring the upkeep and maintenance of supplies and equipment for the units, as well as the general functioning of the patients’ rooms and amenities and the emergency cart; completion of reportorial requirements of staff nurses; and monitoring the upkeep of cleanliness and maintenance of the units’ facilities to ensure maximized operations of the units with minimal costs. When asked what the meaning of management was in her personal opinion, Ms. Rodgers replied that the term management actually involved compliance with functions of planning, organizing, directing and controlling all aspects or areas being governed. Managers create an environment for effective performance. They have the responsibilities of integrating tasks, structure, technology, resources and people into a productive and performing configuration. As revealed, Ms. Rodgers indicated that managers achieve goals through the efforts of people and they have to design strategies to influence the behavior of the people they govern. In this regard, managers have to be leaders, as well. Leadership was noted as the process of influencing people so that defined goals are effectively achieved. Leaders focus on influencing behavior towards the attainment of an identified objective. They could or could not necessarily be managers in organizations. On the other hand,

Local Responsiveness Strategies - Essay Example That is not what has made a big name for the company, which started only as a local coffee bean roaster (Fabricant 1992) The stimulating culture of growth that is apparent in the organization is striking. During its early days, in the 1980’s the company had a habit of opening two stores every day (Ruth, 2007). The management of the company even tried to venture new markets such as the Midwest. Well, some of their prospects did not yield gain as expected, but the visionary strategies employed to achieve those goals directly and indirectly concern our question of the study. For instance using the global standardization strategy, the company can manage to stir local attraction from customers. This concept is usually developed through careful analysis of the status of the company in the global market versus the status that the company wished to be. Thus, it is a series of processes through value chain analysis to seek competitive advantage given the abilities of the company, Star bucks in this case. Findings would most likely show that sales and marketing was one key factor that needed to be addres sed in an effort to establish a powerful global presence for Star bucks. Another strategy that would be vital to Star bucks success in motivating local responsiveness is an effective transnational strategy. This implies that, through a firm organizational structure, a high level of co-operation and interdependence is established leading to a coordinated flow of activities especially the daily operations. It is important to note that the headquarters in Seattle is expected to serve as the vital link to the global interconnection (Fabricant 1992). The result of such a powerful strategy was a resultant domestic attraction thanks to initiatives such as advertising that appealed customers increasing sales. International strategies have also been incorporated into Star buck’s projects, with a view to

Remote Sensing and Image Processing Essay Example | Topics and Well Written Essays - 2000 words

Remote Sensing and Image Processing - Essay Example Moreover, these events also include images and pictures that are captured via satellites that are powered with remote sensing technology. The advantage of remote sensing is that it can detect objects in real time along with providing coverage of an expanded area within a short period of time. However, remote sensing can be divided in to two types i.e. active remote sensing and passive remote sensing. The active remote sensing provides opportunity to be utilized at any time throughout the day and regardless of any season. Moreover, active remote sensing also facilitates the inspection of wavelengths that are not effectively illustrated by the Sun. In addition, it also takes charge of the illumination on the targeted object. On the other hand, passive remote sensing requires the Sun, in order to brighten the objective or the target. Moreover, this type of remote sensing uses reflected waves to measure the distance. As (Smith 2010) states that remote sensing based on active methodology needs a significant amount of energy source for illuminating the target. The data for the process of task that was associated with the vegetation estimation exposure was gathered from the National Oceanic and Atmospheric Administration's (NOAA) Advanced Very High Resolution Radiometer (AVHRR). In order to achieve a detection of vegetation, band rationing of the value of Infra-Red (700-1300nm) by Visible Light (400-700nm) is utilized. By using these values and methods, the albedo effects will be eliminated along with issues related to shadows that emerge from the images that are processed. Moreover, this method will also facilitate high quality visibility for vegetation in images. Moreover, a task that is related to classification of information classes, Churn Farm image is the best option. Likewise, data available in this image is gathered by an airplane in the year 1984 from the NERC ATM scanner. Likewise, the image includes four bands and sketches the sites that are associated wit h agricultural land use. Moreover, integer represents the cover type for specific land cover type, in this way; probable training sites can be marked for each type of land cover. Task 1 - Vegetation Index Methodology This task utilized a methodology including calculation of Ratio Vegetation Index (RVI) and Normalized Difference Vegetation Index (NDVI). The NDVI will be used for the image of Lake Nakuru Thermatic Mapper (TM). Likewise, for data associated with TM, two bands are utilized i.e. band 3 and band 4. Band 3 calculates the red light and band four calculates the red infra light. Outside the scope of the town named as Nakuru, a small salt ware lake named as ‘lake Nakuru’ is located. Likewise, the lake is famed for the spectacle, as approximately one million flamingos comes to it for feeding themselves with green algae located in the warm water areas of the lake. Moreover, pelicans often come here to feed themselves with cormorants that are also available deep in t he lake (Smith 2010). Steps Implemented Steps are demonstrated in points below: Considering as a Raster Layer, open the image file named as nakuru.img. In the available options, select the option to view the image with channel 4 that will be associated with green gun and red gun. However, channel 2 will demonstrate blue gun.

Open Term Paper Example | Topics and Well Written Essays - 1250 words

Open - Term Paper Example Capital punishment has been abolished in many US states with others passing bills to abolish it in the near future. There was a lapse of four years in handing out capital punishment in the United States of America in 1972. The practice resumed in 1976 and is still being carried out. Considering both sides of the argument and weighing pros against cons, it is better to do away with capital punishment once and for all from the justice system of the United States of America. In our present legal system, there are chances of false falsely convicting individuals. The strongest argument against the death penalty puts forth the hypothesis of an individual being falsely convicted and sentenced to death. Research shows that this hypothesis has come to pass in several cases such as a case in Illinois in 1983 where two men were falsely accused of murder of a 10 year old. After having spent 10 years on the death row waiting for the date of execution, their innocence was proved by defense when DN A evidence cleared them of the charges (Donohue, and Shavell x). If the American legal system had not been slow, two innocent men would have lost their lives for a crime they did not commit at the same time allowing the real culprit to roam free. And if the discovery came after the sentence was carried out, how would the state go about posthumous redress? More than 130 similar cases have come to light in the past 37 years where 130 individuals were found innocent after having spent time on death row (DPIC FactSheet). Questions and incidents such as this one shake the resolve of those in favor because, once death penalty is carried out, the executed cannot be brought back to life. In case of time served, some sort of financial redress can be offered. Capital punishment provides room for abuse. Another argument that is loosely connected to the preceding one is the conviction of the mentally disabled. There are several mental conditions, psychological disorders amongst them, that make individuals who are suffering from them commit acts of violence. It can be argued that these people, whether because of depression, delusion or under the influence of medication that they take to treat these ailments, may commit murder. Though there is a consensus that such people should not be awarded capital punishment, however, as long as capital punishment remains a viable option, there is no way to ensure that such verdicts are not passed. For instance, in the State of Virginia a borderline mentally challenged woman, Teresa Lewis, was awarded the capital punishment (Szkotak). Lewis, despite being mentally retarded and despite not being the actual perpetrator was executed just because the option was available. If capital punishment is abolished, the option would not be present to be taken into consideration in the first place. Death by legal injection is seen by many as cruel and unusual punishment. The current method of execution, the lethal injection is a mixture of deadly sub stances with potassium chloride being the active ingredient. It is introduced intravenously into the human body. If not in the correct ratio or if not administered properly, the lethal injection can cause a slow and agonizing death. In most cases, potassium chloride merely causes paralysis and the poor individual is painfully aware of every sensation till his or her last breath.

Letting the Big Ones Get Away - Case Study Example This discussion stresses that another standard that applies in respect of prosecutors is that they should refrain from initiating or encouraging efforts to waiver rights from an accused person who is unrepresented. According to Gershman, prosecutors should maintain neutrality. Some of the dilemmas that prosecutors have to deal with include those related to knowing use of false evidence, threatening a person of criminal prosecution with the aim of discouraging them from appearing before the court as a witness. It is also unethical for prosecutors to present false statements of material fact during court proceedings. In the case of the big-name drug dealer and his girlfriend, it is a fact that the prosecutor must uphold justice above his desire for promotion. In addition, he/she should see to it that instead of trying to convict, his duty to justice remains steadfast. Clearly noting, the deal that the drug dealer presents to the prosecutor in respect of transferring his case to his gir lfriend if accepted by the prosecutor will present a situation in which justice is defeated. This is so considering that the big one will be let off the hook and someone innocent in respect of the drugs will be the scapegoat. Furthermore, subjecting the innocent pregnant girl to charges is tantamount to punishing the unborn child for a wrong neither it nor its mother committed. The drug dealer by all means should face justice for his actions. Given that he is well connected and has escaped from the rule of justice several times shows that he is unwilling to change his cause. Furthermore, accepting his offer will result in the defeat of justice in respect of his pregnant girlfriend. However, the strength of the case lies with the girl’s cooperation.

Criminal Investigation - Essay Example forensic pathologists will be able to determine the subtle differences among near-contact gunshot wounds, contact gunshot wounds, distant gunshot wounds, medium range gunshot wounds. The determination of the nature of Sam’s wounds will be possible since the process involves the use of experience and technology to ascertain various significant details on Sam’s death. According to Siegel (2009), some of these details that are relevant to Sam’s three wounds will be range, direction, sequence of firing pattern and the path that will have been travelled between exit and entry wounds. In the same respect, the likelihood of Sam surviving the gunshot wounds can also be determined to help find out whether there are other forms of lethal harm that may have been inflicted upon the victim. Again, by studying Sam’s wounds, it is possible to determine the type or model of firearm that was used. Should the analysis yield different results, then it will be obvious that di fferent guns may have been used (Siegel, 2009). From the wounds that Sam incurred, it is possible to classify them as defensive wounds, or wounds that may have been inflicted by sentient beings. The presence of defensive wounds may not only indicate wrongful death, but also the murderer’s proximity to Sam. The crux of the matter herein is that Sam’s wound will be helpful in helping the police with extensive crucial

Chapter 8 Unemployment Taxes Essay Example | Topics and Well Written Essays - 750 words

Chapter 8 Unemployment Taxes - Essay Example Fines and interests are common but they can be avoided by depositing the taxes when due, filing the 940 forms accurately and within the stipulated time and finally by ensuring that the checks issued during tax payments are valid. State Unemployment Tax (SUTA) is not deducted from the employee’s wages in most of the states. They are usually paid by the employers. They are paid on top of federal unemployment taxes owed by the employer. Most employers who pay state unemployment tax are required to pay Federal Unemployment tax that is included in Form 940. It is deemed to be late by the federal government if submitted later than January 31 of the subsequent year. A state is said to be in a state of credit reduction if it has borrowed funds from the US federal government to help run the development activities but able to pay back the loan by the agreed time frame. Some states allow a voluntary contribution to reduce the state unemployment tax rate. Explain how this works and what does it accomplishes for the employer. How many states have this provision? Is it always a savings? Why or why not? Do Missouri and Illinois allow voluntary contributions? Voluntary contribution is an alternative practiced by employers in an attempt to reduce their tax rate and maintain them low. They opt to voluntarily pay some or all of the benefits paid to former employees instead of paying them through an increased unemployment tax rate. It is practiced in 23 states in the US. Partial benefit payment is a departmental term that is used to describe unemployment composition of less than the weekly amount of benefit that is paid to the claimant. Its sole purpose is to ensure that former employees still get some pay from their employers even after their employment has been terminated. The payments are made when the individual participates in odd jobs or subsidiary work that is not equal to the usual

The Art of Grilling Essay Example for Free

The Art of Grilling Essay After coming home from a long day of going to classes and studying there is one thing that I especially look forward to. Some people may want to go grab a beer or turn on the T. V and lounge around, but my vision of a perfect evening is one spent in front of a grill, cooking whatever it is Ive chosen for dinner. Im not sure why I like to grill so much but my guess would be because my dad loves to. Im from Tampa so it was never to cold to grill and a day rarely passed, rain or shine, that my dad wasnt out grilling something. I actually thought it was normal to grill everything, and I mean everything, until I was about 13. Fruits, vegetables, meat, you name it, my dad grilled it. Because I enjoy grilling so much I have decided to let you know exactly what the art of grilling is. Today Im going to discuss three topics, types of grills, types of food to grill, and to finish it off, some basic grilling techniques. The definition of grilling is cooking an ingredient over high heat, on a metal grill. On the grill food is cooked quickly because of the heat coming from a gas, electric, charcoal, or wood heat source. The first way to grill I will discuss is by using the wood grill. Wood grills are the oldest and most primitive way of cooking. Today wood grills are obviously more advanced than the one used by people hundreds of years ago, but the heat source is still the same, burning wood. Although charcoal and gas grills are more commonly used these days, wood grills are still thought of as a great heat source because it perfumes the grilled item with a smoky flavor. Experienced wood grillers' advice is to make sure to let the wood burn down in to embers before cooking, because grilling on an open flame will easily burn the food. According to the Culinary Education Center website, The best kind of wood to use when using a wood grill is hardwoods, such as fruit wood, hickory, or mesquite. The next types of grill I will be talking about are electric and gas grills. These two are usually grouped together because they are the easiest to use. Lighting them is as simple as pushing a button or flipping a switch. Also, unlike wood and charcoal grills, these grills keep a steady heat across the grilling surface. In the past, gas grills were always used more because of the electric grills inability to reach a high heat. Within the last couple years electric grills popularity has risen because of their new ability to reach and sustain a high heat and because they are considered safer in a home environment. These two types of grills are definitely the quickest way to cook dinner. The last type of grill I want to tell you about is the charcoal grill. Charcoal grills used to be the most common grill used in family homes, but as the electric and gas grills became more popular charcoal grills are now mostly used on camping trips or picnics. In addition to the other grills being safer, there is also a hassle in lighting charcoal grills. According to an article on the website of Learning the Art of Grilling at Home, charcoal grilling is cheaper but more troublesome to light and keep at a steady temperature. It takes 30- 45 minutes after lighting the charcoal until you can actually cook on it. Personally, charcoal grilling is my favorite because in my opinion it makes the food taste better. Unfortunately, because of the hassle that goes along with a charcoal grill, they are now a dying trend. Now that we have the three types of grills out of the way lets move on to what you can actually cook on them. The best types of foods to cook on a grill are red meat, poultry, vegetables, fish, and fruit. When choosing a red meat to grill you should try to get the most tender cut of meat, such as a filet or strip because on a grill there isnt enough time for the meat to tenderize by themselves. Another type of food to cook on the grill is chicken. Chicken is the most grilled items in households across the US. When cooking chicken, leaving the skin on will prevent the chicken from drying out and will also taste great when its finished. If you are cooking a skinless chicken breast you will need to be more careful because it is very easy to overcook them and dry the piece out. The same goes for fish. Fish tastes great on the grill but overcooking it will cause it to be dry and not taste very good. Vegetables such as squash, mushrooms, and peppers are also great. After a dip in oil, and some salt and pepper you will be amazed at how good they taste right off the grill. The last food that I will suggest cooking may surprise you. Fruits such as apples and pears are great after being thrown on the grill. All they need is just a little warm-up on the grill and it will completely enhance the flavors of the fruit. The taste will really surprise you. Ok, the last thing Im going tell you about today are some basic grilling techniques. First, you want to turn the grill on and turn the temperature to high, make sure the grill is hot. The Culinary Education Center says if the grill is not hot, it will be hard to develop the caramelized, smoky flavors of a properly grilled meat. Also, if the grill isnt hot the food youre cooking will stick to the grilling surface. After making sure the grill is hot you will want to clean off the grill surface with a wire brush. This cleans off any old pieces of food left on the grill. Finally you can now toss the food of your choice on. Barbeque N on the Internet says the goal of perfect grilling is to give the item delicious, brown grill marks on both sides, while making sure the item comes off the grill at jus the right amount of doneness. Today I hope I taught you a little bit about grilling that you didnt know before. I also hope you can now understand my weird obsession with grilling. An article I read in The Sun Valley Guide for Grilling said it best, food cooked over a fire, simply tastes better.

The Challenges Posed By Digitalization And The Internet Media Essay

The Challenges Posed By Digitalization And The Internet Media Essay No part of this book may be reproduced or transmitted in any form or by any means, electronic or mechanical, including photocopying, recording, or by any information storage and retrieval system, without permission in writing from the publisher? Perhaps, we all have read this phrase or a similar phrase somewhere at sometime. Similar warnings can be found in the movie credits, covers of music albums and similar other digital works which we can find in the Internet and other digital devices. How many of us have actually paid heed to such warnings? Almost always, nobody does. Everybody uses the Internet as if it is a limitless source of all that we need and want. The Internet is one big library. It is made up of numerous computers and devices which are connected together and carry data which can be transmitted to the other computers in the database. It has all the information that everyone virtually needs. Books, music, photos, news and many other kinds of information can be found on the Internet. Some for free and some for a fee. It is one big library without a librarian. And that is where the big problem lies. Nobody actually monitors what information you get from the internet and how you intend to use it. Most of the time, you can save or download any information that you need and do whatever you want to do with it at the click of a button. The Internet not being owned by anyone nor controlled by anyone is thus considered as a public domain. Everybody can have access to digital information which is usually free and available for all. With the Internet, the privacy of millions is threatened. Is there anything that we can do if a photo we posted online is being reposted by someone unknown in another website? Can we stop another person on the other side of the globe from copying the thoughts that we have posted on the blog? Are there even laws spanning across territories that we can invoke to protect us? Is it even possible to know and pinpoint who the person responsible is? Almost always, the answer to these questions is a big resounding No. This privacy problem is even compounded in areas of Intellectual Property. It refers to those property rights which result from the physical manifestation of original thought (Martin, 2002). Copyright is one of the areas covered by Intellectual Property Laws. According to the World Intellectual Property Organization, Copyright refers to that system of legal protection an author enjoys in the form of expression of ideas. This covers protection given to authors with regards to his scientific, educational, literary or other works; musical compositions of a composer; painters and other artists with respect to their work of arts; and many others not limited to such enumeration. Prior to the era of digitalization and the Internet, these copyrighted materials only exist in printed form, usually on paper or on canvas. These works have specific laws which protect their use from infringement. Any unauthorized reproduction, distribution, display or derivatives can be considered infringement, subject to certain rules and standards set in the laws. However, as we have reached the digital age, these works have been made available through the Internet also. Due to this, the problems have arisen, problems which have not been covered by most Copyright laws. What constitutes reproduction or distribution or display in tangible form does not equate to reproduction, distribution or display over the Internet media. Strictly speaking a work cannot be the subject of an infringement unless there is something tangible which shows such. The same no longer holds true with the digitalization and Internet. The Copyright System and Laws are thus unable to effectively respond to the challenges posed by digitalization and the Internet. The Challenges Posed by Digitalisation and the Internet We know that schools, businesses, hospitals and various other institutions have date which can be useful to other organizations. Many of these data can be accessible by digital copies and through online. This resulted to the era of databases which can be accessed by almost everyone in the planet. Some argue that this is an invasion of privacy as well as an infringement of copyright rights. Copyright may be vested in a work closely similar or even identical to an earlier, already patented work, provided that the former is truly original (Martin, 2002). The Internet, as helpful and convenient as it is, has been a cause of a major problem when it comes to intellectual property laws. The Internet has paved way for the unauthorized collection, use or sale of copyrighted materials. It is not only famous authors or artists which are protected by copyright laws. Davis (1997) once suggested the idea that individual users of the Internet also have property rights. Whatever we write or put on the Internet which are from our own personal thoughts or ideas or works are our own private intellectual property and as such we have the right to protect it and should not be copied by just about anyone online. Copyright puts a limitation on the volume of information or material that a person can reproduce without getting a license to copy first (Gillespie, 2007). A copyright can also be a limitation on artistic choices as artists cannot even make artistic works which are similar to that which has already been copyrighted (Burrell Coleman, 2005). This may sound as nothing important for Internet users but for people who are the owners of copyrighted works, this is very important. Many people in fact do not understand the idea of Copyright Laws and how it works. Lets examine the case of authors and the books they write. With the digitalization and the Internet, books in paper have been transformed into electronic books and can be easily saved in millions of copies in a device even smaller than a matchbox. Electronic books, otherwise called ebooks are books in electronic form which can be read on the computer or any ebook reader device (Schwabach, 2006). These days, people dont buy books as often as before. Thanks to the Internet. Or perhaps, no thanks to the Internet? Remember way back ten years or more ago, people buy encyclopedias, almanacs and atlases which come in 20 book sets or more. People buy Bible books for children in sets of 10 or more. Often, these are done in set-ups of monthly installments which in this day and age seem illogical. Why would you need 20 books when you can just Google? Why would you need four feet of space for a set of books and magazines when you can just buy a computer and use two feet of space for information which cannot be contained in even a room full of books? We admit, more and more people are reading ebooks, they are cheaper, they do not take space and they can last a lifetime. Many of these ebooks can be copied online for free and are allowed to be disseminated over the Internet for several reasons, such as when they are already available in the public domain or the author chose to publish it free for all (Schwabach, 2006). However, not all authors are like this. There are also many authors who have placed restrictions in the ebooks and thus do not allow any unauthorized or unpaid copies to be made and distributed. There goes the problem with the Copyright Laws. Another favorite in the Copyright infringement with this boom of the digital and Internet era is the mass reproduction and dissemination of movies. Movies are cinematographic works of art. Usually, the producer has copyright for purposes of exhibition; for all other purposes, the producer, the author of the scenario, the composer, the film director, the author of the work are the creators and thus have the copyright protection. In this day and age, anyone can download movies through the Internet and store them in memory drives. One downloaded movie can be reproduced a million times, recopied in DVDs, transported to different areas of the globe, and watched in millions of homes countless times. This is very common and not everyone knows that this is actually infringement. Third scenario, have you ever heard of controversies involving speeches made by people and would later be found to be copied verbatim from a speech made on the other side of the globe and which can be found online? We have heard of these a lot. You can use it as a speech in a remote area and when fortune favors you, nobody would ever know that you copied that piece from an article you read online. No one will ever know and everyone who has listened to such speech will think of how brilliant a speaker you are. Little did they know, you not only plagiarized the speech, you have also broken certain laws. Yes, you are in the eyes of the law, a criminal. In these scenarios, somewhere, someone has the right to relief and damages for such mass reproduction and dissemination of the movies, for the plagiarized speech, for the ebooks which have been copied and passed hundred of times. The one who is responsible for the infringement exposes himself to criminal liability wherein the law prescribes penalties of imprisonment and fines. This can be easy in the past. But in this world of vast connection of wires all over the globe, how easy is it to catch who is responsible? How can authors, musicians and artists ask for damages when they do not know in the first place who is responsible? And, is there really a clear law which defines infringement of Copyright laws over the Internet? In the past, it has been clearly laid down what constitutes copyright infringement and which doesnt. In the past, it has been clearly laid down who is entitled to copyright protection. In the past, it has been clearly laid down who owns the copyright. In the past, it has been clearly laid down what constitutes Fair use. The Fair Use Doctrine refers to the fair use of copyrighted work for the purpose of criticism, educational purposes, news reports, research and other similar purposes. Fair Use does not constitute infringement. In this instance, fair use in tangible media and fair use over the digital networks and the Internet seem to be the same. In the payment for damages, some laws lay down rules on assessment on the basis of the proof given by the author or artist of sales made by the infringer of the infringing work deducted by whatever costs the infringer may be able to prove (Martin, 2002). With the copyright infringement happening on the Internet, sometimes sales do not even take place, there is but a free for all reproduction of copyrighted works. We can see that in addition to losing protection from infringement, the author or artist also loses any chance of getting any amount of damages for compensation. Are information found online in this age of the Internet and digitalisation owned absolutely by their authors or artists, or is there some form of joint ownership with all the other users of the Internet? Does the fact that a copyrighted photo is found online give the Internet users the absolute right to use it? If that is so, then it goes to say that we have all become owners of whatever information that we can find on the Internet, right? Wrong. In some instances, there are owners of copyrighted materials such as music and books which allow specific transfers to internet users without any copyright infringement taking place (Rimmer, 2007). For example, the importation of a copy of a work by an Internet user for solely personal purposes shall be permitted without the authorization of the author of, or other owner of copyright in, the work under certain circumstances as laid down by law. When copyrighted materials are sold over the internet, there is no tangible medium. It is thus only the right to use which is being passed to the one who is buying the copyrighted digital works (Schwabach, 2006). Thus, technically speaking, a digital work which is sold online may not be sold by the buyer to another. That right to sell only belongs to the real owner of the digital work. The buyer only has the right to use, he can read or listen to the digital work but he does not have the right to sell it. The same analogy goes true when buying a DVD. If you buy a DVD and you copy the contents of the DVD and then sell the copied DVD, you are guilty of infringement. These are just some of the hundreds of challenges that are faced by the Copyright System and which have to be dealt with to protect artists, authors and others who have created manifestations of their brilliant ideas. It is therefore important to examine and to address the rights associated with the people who are owners of information or media disseminated over the internet (Gillespie, 2007). We, the billions of Internet users in the planet, are not the owners of every thing that we can find on the Internet. There is nothing to prevent you or me from downloading the latest movies, or posting a video of yourself online singing the latest chart-topping song of a music phenomenon, or posting an exceptionally beautiful painting made by your neighbor and claiming it as your own. A cornerstone in helping the problem with copyright protection is to inform the general public about rights and duties of owners of copyrighted materials and the Internet users (Wolf, 2003). Being socially responsible for whatever we download and use from the Internet may seem like the best possible option at present. Sad to say, but authors and other owners of copyrighted materials do not seem to have any avenue to defend their Copyright protection. Novel efforts must be made to explore how Intellectual Property Laws on Copyright can be amended and streamlined for the digitalization and Internet use. No matter how good the countrys Intellectual Property Laws are, these are still not designed for the digital and the Internet era. These laws have proved lacking, giving more freedom to Internet users and stripping Copyright owners of the Copyright protection that laws have given them. Conclusion What the Internet and digitalization gives away with one hand, it usually takes away with the other. The Internet and digitalization may have opened a whole lot of doors for everyone, but it also creates a very serious problem with regards to the use and abuse of information. Different jurisdictions all over the world have made the recognition that with the boom of digitalization and the Internet, privacy is almost impossible and the laws on copyright are unable to effectively respond to this. Movies, books, music and similar digital works have been the subject of numerous infringement which does not seem to stop anytime soon. Many challenges are faced by Copyright Laws because of digitalization and the Internet. Among these problems are the inapplicability of present Intellectual Property Laws, the lack of control in the information dissemination of the Internet, the easy access and download of various digital works over the Internet and the seeming lack in social responsibility and awareness of many Internet users, to name a few. A lot of people are actually unaware that not everything that we find on the Internet can be copied and used to our hearts content. And even if people knew, they either do not understand or do not care. Besides, what would stop them from infringing copyrighted works? The vast interconnection of wires and computers almost makes it virtually impossible to catch someone who is responsible for downloading and copying several copies of a movie, a song, a book, a photograph or similar works. In conclusion, until a perfect law against infringement of copyrighted digital materials over the internet is made and implemented, or a perfect socially responsible Internet- and digitally-savvy community of users exists, there is no specific and effective solution to help the owners of Copyrighted materials against these challenges that they face in this age of digitalization and the Internet.

Analysis of Mental Illness via Girl, Interrupted (1999)

Analysis of Mental Illness via Girl, Interrupted (1999) GIRL, INTERRUPTED 1 Introduction In the movie, Susanna (Winona Ryder) is diagnosed with Borderline Personality Disorder. Susanna bonds with a few different patients, including Lisa (Angelina Jolie) with sociopathic personality disorder, Daisy; Bulimia, Georgina; pathological liar and Janet as Anorexic. Susanna starts to work harder with her specialist (Vanessa Redgrave) and the medical attendant on the ward (Whoopi Goldberg). Girl, Interrupted was focused around the collection of memoirs of Susanna Kaysen, who truly did put in eighteen months a Psychiatric Hospital (Mangold,1999). DSM V Diagnosis Criteria Consistency Borderline Personality Disorder is defined as a pervasive example of precariousness of interpersonal connections, mental self view, influences, and checked impulsivity, starting by ahead of schedule adulthood and present in a mixed bag of settings as showed by 5 or a greater amount of the following; (a) Distraught endeavors to stay away from genuine or envisioned relinquishment,(b) An example of temperamental and extraordinary interpersonal connections portrayed by exchanging between extremes of admiration and cheapening, (c ) Personality aggravations: especially and diligently instable mental self view or feeling of self,(d) Impulsivity in no less than two zones that are possibly self harming,(e) Repetitive self-destructive conduct, signals, or dangers or self ruining conduct,(f) Full of feeling flimsiness because of a stamped reactivity of mind-set,(g)Chronic sentiments of vacancy,(h)Inappropriate, serious outrage or trouble controlling annoyance, and (i)Transparent, anxiety relate d jumpy ideation or serious dissociative indications (American Psychiatric Association,2013). The first criteria for BPD in Girl, Interrupted, was having self-destructive contemplations and doing things to help a conceivable suicide by endeavoring what Susanna called an impotent endeavor to murder herself by taking a dose of aspirin with vodka. At the point when the attendant attempted to hold her she says to be watchful in light of the fact that she has no bones in her grasp. Later on, the advisor asks her the means by which she got the container of Aspirin in the event that she had no bones in her grasp, she reacts saying then theyd return (Mangold, 1999). The second criterion was incurring damage on the body by cutting or wounding. After she endeavored suicide, she was hurried to the crisis room, and the cam point changed from everyone wildly moving around to help to her wrists. She had wounds everywhere on her wrists and she continued telling the specialists she didnt have any bones in her grasp (Mangold, 1999). The third criterion was Susannas endeavors to stay in the connections to abstain from feeling relinquished. At the center of the film, she has a flashback of the illicit relationship she had with one of the instructors and with a fellow that she met after her secondary school graduation. In both cases, she was having hazardous sex and staying in the connections with the goal that she felt needed and cherished, and not dismisses (Mangold, 1999). The fourth criteria was filling the void that was generally felt by doing something she knew wasnt correct yet provided for her rush. Susanna felt as though nothing was going how she needed it and she was the main individual feeling that way. In the film, Susanna and Lisa, a young lady in the organization, chose to escape the foundation and go on an excursion to visit an alternate young lady that had been there with them, Polly. Both of them knew they could cause harm, yet the proceeded at any rate (Mangold, 1999). The fifth criterion was the point at which she encountered a shift in temperaments and felt like she had no feeling of herself whatsoever. Around the end of the film, there was a period Susanna was persuaded she wasnt going to improve and she got preventive over what Dr. Wick was letting her know about her analysis. She proceeded and expressed how she couldnt have cared less and her new most loved word to portray herself was conflicted in light of the fact that she said it implied she couldnt have cared less any longer and she was going to do whatever she felt was correct (Mangold, 1999). We believe Susanna created these examples all the more in adulthood, yet everything originated from her youth occasions and they are reliably demonstrated in the motion picture concerning the indications of BPD in DSM V; in any case, at one purpose of the film, her sweetheart comes and says that she is not insane and that she doesnt have a place there. She then says, Yet I attempted to execute myself†. This shows how she has disguised what had persistently been tossed at her. He tries to persuade her to flee with him to Canada, however shockingly she says she has companions here and that she herself is crazy. As per Comer, 2010, one of the characteristics of people experiencing BPD is that sentimental sentiments seeing someone are not generally shared. However in the motion picture, in spite of her refusal to flee with him, their shared adoration stays in place, in this manner demonstrating a conflict with the DSM-V as of right now (Mangold, 1999). After a long discussion with the office head, Susanna gets more disappointed in view of what she says and takes a great deal of pills. The following morning she experiences difficulty awakening the superintendent acknowledges what has happened and completes her of quaint little inn her in the shower tub to wake her up. She has a fit, and gets to be exceptionally indiscreet. The superintendent tries to clarify to her that she is not insane and that she is simply a lethargic, liberal young lady who is making herself insane (Mangold, 1999). The following morning Susanna finds that Daisy had submitted suicide by hanging herself and she calls the police and is taken again to the clinic while Lisa vanishes. At the clinic she has a discussion with her Doctor where she says that she wished she could have done something to help Daisy. She additionally states, â€Å"I’ll never know what it’s like to be her but I know what it’s like to want to die, how it hurts to smile, how you try to fit in and you can’t, how you hurt yourself on the outside and try to kill the thing on the inside† (Mangold, 1999). There are a few distinctive perspectives on how an individual like Susanna could have created BPD. One view that scholars have, is that an early absence of acknowledgement by parents may prompt a loss of respect toward oneself, expanded reliance and a failure to adapt to division (Comer, 2010). In the motion picture, Susannas mother made a remark on when Susanna was an infant, she was transforming her diaper and she turned around for a part second and that was when Susanna moved off the quaint little inn her leg. She said the specialist place Susanna in a full body cast and her guardians went on a 4,000 mile outing with Susanna locked in the rearward sitting arrangement in the body cast (Mangold, 1999). Cultural Differences In a collectivist society like Sri Lanka, close family relatives would be exceedingly concerned if an individual showed such feelings or practices. They would be extremely terrified and attempt to do whatever they can, striving to help them. It would not be a theme that would be talked among each other individual, presumably just close relatives and companions. Once an individual has been diagnosed and at last cured, the enduring impression would not be of the said individual being totally recouped. They would presumably still expect or think at the once again of their brain that they are not totally cured or may tend to backslide. Notwithstanding they would at present be extremely steady as it is in their tendency to be so. These relatives and family would likewise feel that an individual being diagnosed with a certain issue is because of the Karma which is the where their circumstance is ascribed to sins of the past births. Some parents of family members are regularly embarrassed to concede that their youngster is having BPD disorder. They attempt to lock their youngsters in a room in order to prevent embarrassment from the society. In the event that the kid does not so much succeed then the youngster is censured, debased or rebuffed, which may influence the kids self regard and trust in a radical manner. One of the principle purposes behind this is on the grounds that the absence of mindfulness about the issue accordingly there is a probability, where the perspective towards the kids and the issue of BPD may slowly change in the promising new years. Conclusion To sum up, the movie indicates how the emotional sickness had a huge effect on Susanna as it demonstrates how she would holler insanely in the night and be extremely befuddled since she didnt recognize what wasnt right with her or felt caught on the grounds that she felt that nothing really wasnt right with her (Mangold, 1999). We personally think she would have gotten better if she was simply at home, while being given personal treatment and care without confining her to a setting that induced, provoked or aggravated her disorder or she could have been given the dialectical behavior therapy which most clinical today utilize this therapy method.

Goblins, Imps, Brownies, Trolls, Pixies, and Bogies †Yesterday and Today :: Exploratory Essays Research Papers

Goblins, Imps, Brownies, Trolls, Pixies, and Bogies – Yesterday and Today In modern day, one is not likely to encounter a goblin in one’s travels, except perhaps those found scurrying after candy on Halloween night. However, goblins, as well as imps, brownies, trolls, pixies, and bogies were once considered as much a part of daily life as cows and chickens.(Briggs, These were the fairies, the half-natural, half supernatural beings that helped and haunted mankind throughout most of the world. The Scottish divided these fairies worldS into two groups, the Seelie Court, those helpful to humans, and the Unseelie Court, those who were mischievous, misleading, or downright evil. At the lowest rungs of the Unseelie court, one would find the goblins. (Briggs, 357) The goblins have changed, however, since these dark times, and it is the purpose of this paper to show the evolution of these monsters from medieval fairy, to subterranean miner, to Sauron’s horde of minions, and into other various modern-day incarnations. Additionally, the cul tural driving forces of feminist theology, Freudian psychology, political agendas, and technological fears will be used to explain several of the more notable goblin literary works. Finally, it will be shown how the medieval concept of the goblin, the fairy trickster, will resurface after a hundred years of exile in the form of the gremlin. The goblin as a fairy has its roots mainly in Britain, although they had counterparts in most of Europe. The French had goeblins, the Germans kobolds, the Welsh pwca (pooka), and even the Japanese had the tengu. However, the name ‘goblin’ is attributed to an Italian origin. The story goes that in Florence there were two infamous houses, the Guelfs and the Gibelins. So malicious were the members of these families that mothers would warn unruly children that the Guelfs and the Gibelins would come to get them if they did not behave. Thus the modern words ‘elves’ and ‘goblins’ were born. (Latham, p. 48) The fairy goblin ranged in disposition from the truly sinister to the near-harmless trickster.
