JFK STeel Mill Essay free essay sample
In his speech to the people of the United States of America, president Kennedy uses repetition and offers solutions with a very imperative tone to convey his opinion that steel companies are causing harm by making their prices higher. He continues to argue that in a rising industry, they are the cause of jobs being lost, and that because of them, the country will be further in debt. After catching the reader’s attention and undermining the steel corporation’s ideas, Kennedy solidifies his speech by using imperative syntax, which adds a sense of urgency to the situation. He constantly affirms the seriousness by using the word â€Å"necessary†and providing solutions to solve the problem. JFK states, â€Å"And it is necessary to stem it for our national security, if we are going to pay for out security communications abroad†(Kennedy). This quote shows that the country needs to take action over the steel industry for progress to come and for the country;s safety to be upheld. We will write a custom essay sample on JFK STeel Mill Essay or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The repetition of â€Å"necessary†and his many quotes on protecting the nation reinforce his imperative tone throughout the speech, and shows the message of economic change and awareness that he pursues in this reply. Then, Kennedy uses the ethical appeal, which refers to the credibility, character and confidence of an author. There are many ways in which an author can create this appeal. During the time period in which it was written, cold war tensions were still lingering and Kennedy had just won the position as president in a very close election over an accomplished opponent. Therefore, just as this problem emerges, the nation is vulnerable and tense and has reached a turning point in history. Since he was elected president, the audience views him as an authoritative figure whose speech should be respected. Although Kennedy was young, he still faced critique on his tone and image, so it was expected of him to exhibit hope and compassion, while criticizing the steel industry. He continually opposes the actions of the steel industry in order to maintain his credibility, especially when he points out that, â€Å"The fact of the matter is that there is no justification for an increase in the steel prices. [ The Industry] was to achieve an agreement which would make unnecessary any increase in prices†(Kennedy). In stating this, JFK blatantly attacks the actions of the industry, making it plain to viewers and listeners that he was completely against this change in pricing. Also, throughout his speech, he presents and explains many quotes and statistics which prove the issues wrongfulness and prove the points he is maintaining. In doing these things, he establishes Ethical Appeal with his listeners and makes his speech much more trustworthy and agree-able. In conclusion, by establishing Ethical Appeal and pursuing an imperative tone through repetition, President John F. Kennedy created a powerful oratory protesting the rise in the prices of steel in the early 1960s. This speech was an efficient way to combat this terrible and harmful decision made by these companies, not only being able to protest the issue, but also accomplishing the unification of all Americans on a cause to end the rise in prices.

Consumers Warned of Online Payday Loan Sites
Consumers Warned of Online Payday Loan Sites As you look at the automated ads that surround this article, keep in mind that the Consumer Federation of America (CFA) has long advised consumers to exercise extreme caution when using internet payday loan web sites, where loans due by the next payday, can cost up to $30 per $100 borrowed and borrowers typically face annual interest rates (APRs) of 650%. According to a CFA survey of one hundred Internet payday loan sites, small loans involving electronic access to consumers checking accounts pose high risks to consumers who borrow money by transmitting personal financial information via the internet. Automatically Zapping Your Bank Account Internet payday loans cost up to $30 per $100 borrowed and must be repaid or refinanced by the borrowers next payday, said Jean Ann Fox, CFAs director of consumer protection. If payday is in two weeks, a $500 loan costs $150, and $650 will be electronically withdrawn from the borrowers checking account. Many surveyed lenders automatically renew loans by electronically withdrawing the finance charge from the consumers checking account every payday. If consumers fail to have enough money on deposit to cover the finance charge or repayment, both the payday lender and the bank will impose insufficient funds fees. Where Payday Loans Lurk Online payday loans are marketed through e-mail, online search, paid ads, and referrals. Typically, a consumer fills out an online application form or faxes a completed application that requests personal information, bank account numbers, Social Security Numbers and employer information. Borrowers fax copies of a check, a recent bank statement, and signed paperwork. The loan is direct deposited into the consumers checking account and loan payment or the finance charge is electronically withdrawn on the borrowers next payday. High Cost, High Risk Internet payday loans are dangerous for cash-strapped consumers, stated Ms. Fox. They combine the high costs and collection risks of check-based payday loans with security risks of sending bank account numbers and Social Security Numbers over web links to unknown lenders. CFAs survey of 100 Internet payday loan sites showed that loans from $200 to $2,500 were available, with $500 the most frequently offered. Finance charges ranged from $10 per $100 up to $30 per $100 borrowed. The most frequent rate was $25 per $100, or 650% annual interest rate (APR) if the loan is repaid in two weeks. Typically loans are due on the borrowers next payday which can be a shorter term. Only 38 sites disclosed the annual interest rates for loans prior to customers completing the application process, while 57 sites quoted the finance charge. The most frequently posted APR was 652%, followed by 780%. Although loans are due on the borrowers next payday, many surveyed sites automatically renew the loan, withdrawing the finance charge from the borrowers bank account and extending the loan for another pay cycle. Sixty-five of the surveyed sites permit loan renewals with no reduction in principal. At some lenders, consumers have to take additional steps to actually repay the loan. After several renewals, some lenders require borrowers to reduce the loan principal with each renewal. Contracts from Internet payday lenders include a range of one-sided terms, such as mandatory arbitration clauses, agreements not to participate in class action lawsuits, and agreements not to file for bankruptcy. Some lenders require applicants to agree to keep their bank accounts open until loans are repaid. Others ask for voluntary wage assignments even in states where wage assignments are not legal. CFA advises consumers not to borrow money based on giving a post-dated paper check or electronic access to a bank account as security. Payday loans are too expensive and too hard to repay on the next payday. CFA advises consumers never to transmit bank account numbers, Social Security numbers or other personal financial information via the Internet or by fax to unknown companies. Consumers should shop for lower cost credit, comparing both the dollar finance charge and the APR to get the lowest cost credit available. For help with financial problems, CFA urges consumers to seek credit counseling help or legal assistance.

Popular, but NOT Working Tips from Professional Resume Writing Services
Popular, but NOT Working Tips from Professional Resume Writing Services Popular, but NOT Working Tips from Professional Resume Writing Services When you want to get a new job, you know about your personal intentions and the exact reasons you want to work for a particular company. In an attempt to write a perfect resume, you many go ahead to check out tips provided online by professional resume writing services. While some of these tips may be awesome, some are quite harmful. Below is a list of some bad tips published by different resume writing services. Tip 1: Don’t Write an Objective Statement Employers do read your resume objective, and over and over again, they go through vague important issues like career objective. When you are attempting to build a career, or even if it’s a horizontal career change, you have to give employers something that focuses on their needs as well as on your own. Such as: A challenging marketing position that permits me to contribute my abilities and skills in fundraising for nonprofits. However, an objective statement may simply be a waste of valuable space, particularly if you’re applying to a PR firm as a PR rep. Tip 2: Highlighting Duties Its quite easy to slip into a mode where you basically list job duties in your resume. For instance: Attended group and recorded minutes; worked with kids in a daycare setting. Employers, however, care less about what youve done as much as what you achieved in your various activities. Theyre looking for statements like: Utilized laptop to record minutes of weekly meetings and assembled them in a Microsoft Word-based document for future reference. Developed three daily exercises for preschool-age kids and set them up for a 10-minute holiday program performance. Tip 3: Make It Simple Short Regardless of what you may read or hear, there are no genuine principles governing resume length because it will be read by individuals who have different preferences and expectations where resumes are concerned. That doesnt mean you should start sending out five-page resumes. You usually need to constrain yourself to a maximum of two pages. You may, however, use one page if it seems working. Alternately, in a bid to make your resume fit to an arbitrary one-page standard, dont cut the meat out of it. Tip 4: Highlight Your Most Relevant Experiences It’s absolutely wrong to state that â€Å"making your resume demonstrate you have only the specific skills, and achievements important to carry out the job, makes it simple for the hiring manager to see why you’re the right fit.†You might be surprised, but companies don’t hire resumes, they hire people. You don’t know whether HR manager wants to see you volunteering for an organization or being the students’ union president of your college. And while the hiring manager sees this in your fellow applicant, that fellow applicant gets the job ahead of you. Of course, it doesn’t mean you should list everything you have ever done in your life, but there is no point in deciding whether something you are proud of is relevant to the position you want to get. Tip 5: Do not Attempt a One–size–fits–all Approach It might be a rule of resume writing that you should send a different version for each job you apply to, tailored and targeted according to the position (a fallacious rule, though). Create a one-size-fits-all resume to send to all employers, rather than waste time separating your skillset. At the same time, spending extra minutes on developing a separate cover letter for different organizations is a really cool idea. In this cover letter, you can emphasize some of your skills making you the best choice for this position. Tip 6: Don’t Steal the Exact Wording of the Job Description Who says this If a company says it’s looking for applicants who â€Å"have a diverse knowledge of programming languages†and â€Å"learn rapidly,†it may be wise to find a way of paraphrasing it, however, it is wiser to sneak it in subtly. Don’t be shocked that some companies will use that as a keyword in screening applicants, especially if they are numerous. The myth behind resume writing is that nobody can express your own qualifications and enthusiasm for a job better than you.

Roman Civilization Essay Example | Topics and Well Written Essays - 1000 words
Roman Civilization - Essay Example In addition, military leaders won considerable popularity among the people by their impressive victories and opposition to traditional senatorial government. The most telling examples of how an influential leader could ascend to the pinnacle of power, pushing into the background the other political institutions, are Marius with his 7 consulates, Sulla, eventually becoming a dictator, unlimited by time or by law; Crassus and Pompey, repeatedly achieving their consulate, and, finally, Caesar. The reform of the army, which became a fundamentally important aspect of Roman history started at about 107 BC during the war between Rome and the Numidian king Jugurtha. This war got a particularly scandalous publicity, since the enemy was so shamelessly bribing the senators that the decline of their authority led to the fact that the Roman army came under the command of Gaius Marius. To combat a powerful enemy for the first time in the history of Rome access to the army of volunteers was opened regardless of social class (the landless, impoverished city dwellers, etc.). Service in the army turned from an honorable duty into a profitable profession; soldiers received salary and were promised land. Organization of the army was improved (Marius introduced division of the legions to cohorts, each consisting of 3 maniples of 200 people), as well as command in general, technical equipment, etc. As a result, the Roman Republic got a well-organized professional army. On the other hand the army has turned into an independent social force with its own interests, needs and requirements. Military reform has laid the conditions for the extreme increase in power of individual military chiefs, as opposed to the weakening of central authorities, which lost the competence in military sphere, and along with it power functions: The acceptance into the army of persons who had few and eventually no roots in the State would have demoralizing consequences, and enable the generals of the first ce ntury to use their armies as though they were their own (Smith 63). Due to the elevation of individual political figures the inevitable structural changes took place in the state apparatus. In particular, a number of extraordinary and ordinary magistrates appeared which have received incomparable power. The role of a military leader increased manifold; and such leader was able to use the army as a weapon in the struggle for power in the state. As the first example of this we can consider the consulates of Gaius Marius, which were received in absentia, contrary to the republican tradition, almost continuously: in 107 and since 104 to 100 BC. Other examples include series of extraordinary powers given to Pompey since 78 to 52 BC, when he got an institutionalized by the Senate sole authority over the state. The anti-Senate forces, led by Caesar, Pompey and Crassus, known as the first triumvirate depended greatly on the army. Probably, the strongest influence of the army displayed itsel f in the civil war. The war that began in 49 BC was caused exclusively by the ambitions of the colonial emperor and his troops; though â€Å"Caesar stressed throughout the willingness of his troops to support his cause†(Keppie 103) it was not justified by any social or political programs. This was the conflict between the pretenders, each of whom found

The Evil Eye Essay -- essays research papers
The Evil Eye Edgar Allen Poe shows us the dark part of human kind. Conflict with in ones self, state of madness, and emotional break down all occur within this short story. The narrator of the story is a mad man that is haunted by his idea that the old man has an evil eye. Through the first person narrator, Edgar Allan Poe’s "The Tell-Tale Heart" illustrates how man’s imagination is capable of being so vivid that it profoundly affects people’s lives. The manifestation of the narrator’s imagination unconsciously plants seeds in his mind, and those seeds grow into an unmanageable situation for which there is no room for reason and which culminates in murder. The fixation on the old man’s vulture-like eye forces the narrator to concoct a plan to eliminate the old man. The narrator confesses the sole reason for killing the old man is his eye. The narrator begins his tale of betrayal by trying to convince the reader he is not insane, but the reader quickly surmises the narrator indeed is out of control. The fact that the old man’s eye is the only motivation to murder proves the narrator is so mentally unstable that he must search for justification to kill. In his mind, he rationalizes murder with his own unreasonable fear of the eye. The narrator wrestles with conflicting feelings of responsibility to the old man and feelings of ridding his life of the man’s "Evil Eye". Although afflicted with overriding fear and derangement, the narrator still acts wit...

The Gender of Power: Latin American Dictatorship
Throughout history men, women and children have been subject to harsh ruler-ship, generally under a patriarchal system. With the emergence of a female role in one of the most coveted dictator positions, one would ask the question: Is feminized power less ruthless? In Gabriel Garcia Marquez's â€Å"Big Mama's Funeral†we learn that although a female has stepped in to the office of a leader, her power is still abused and misused like any other. Latin American history has proven to be one of the most affluent in terms of poor utilization of wealth and power. We have also learned that man or woman can strive in the role of a leader, and that followers will pay mercilessly for the simple fact of living and being. Big Mama is the living proof that power is genderless. The lifestyle lead by a dictator as powerful as Big Mama herself is quite consuming regardless of her gender. The protection of her kingdom and her fortunes were her prime concerns, along with the assurance of her matriarchal rigidity. Her absolute power reigned over the kingdom, slaughtering any who opposed her and every person living within her kingdom had to pay their dues. Residents even believed Big Mama â€Å"was the owner of the waters, running and still†¦Ã¢â‚¬ , even the â€Å"air they breathed†. She was the richest and most powerful matron in the world, although no one knew the the exact value of her estate. She was considered by most of the inhabitants as immortal, to them, she was bigger than life itself. Her stern sovereignty was questioned by none. Her family consisted of brute and loyal soldiers who followed her every command without question. She had built a fence to further protect her and her possessions. The land which she occupied had been passed down from generation to generation. Big Mama had been â€Å"Macondo's center of gravity†, as had her brothers, her parents and the parents of her parents in the past, in a dominance â€Å"which covered two centuries.†She believed she would live well over a hundred years as did her maternal grandmother. The thought of provoking death in Big Mama was laid to rest as most of her tribe members were true believers in her. Although she was mean-spirited and relentless, she tried to uphold a very high-class and honourable image of herself, unlike many other crude rulers of her time. She was two-faced and and everyone knew it, though no one would ever approach her in fear of what she might do to them if she found out they knew. In troubled times, Big Mama contributed secretly for â€Å"weapons for her partisans†, but came to the aid of her victims in public. That patriotic zeal â€Å"guaranteed the highest honours for her.†Big Mama was a master of concealing her hostility and she was proud of the fact that she could. The power invested in a woman such as Big Mama could lead anyone to believe that authority, by man or woman could be ruthless. There is no way of determining whether one or the other could produce more or less wrath. This type of power could put anyone in their place and would terrify even the harshest of critics. Big Mama reigned over the city of Macondo with a cold heart and a tight grip. Her family members supported her every decision in belief it was in all of their best interests, they were true believers. Her self-image was was so god-like, she would never come to realization that every one who knew her in fact despised her.

3 Factors That Influence the Rate of Return Essay
Any bondholder, or any investor for that matter, will allow three factors to influence his or her required rate of return. The three factors are the following: real (pure) rate of return, inflation, and risk premium. These three factors equal the risk free rate which is the rate of return of an investment with no risk of financial loss. This is also the rate that investors would expect from an absolutely risk-free investment over a period of time. Inflation is the constant and progressive increase in the prices of goods and services. If the total rate of return was below the actual economic interest rates then this would cause the lender (investor) to pay the borrower for use of his or her funds. So instead of creating mass chaos in our economic system, the inflation premium of interest rates results from lenders compensating for expected inflation by pushing interest rates higher. An example that can derive from taking the inflation premium into account is that when inflation is high, or expected to decline, look for long-term fixed rate bonds to â€Å"lock in†high market values. The real rate of return and the inflation premium determine the risk free rate of return. As an example, if the real rate of return were 2 percent and the inflation premium 3 percent, then we can say that the risk free rate of return is 5 percent. The real rate of return is described by our Corporate Finance book as the financial â€Å"rent†the investor charges for using his or her funds for one year. For example, if you make a $10,000 investment that earns 8% in one year, you would end the year with $10,800. So, you earn an extra $800, however, if inflation is at 3% for the year, your $10,800 is only worth $10,500. Your real rate of return is only 5%. Investors depending on dividends or interest from bonds are most affected by the costs of inflation. Stocks can be a little safer because companies can pass the higher cost of inflation to customers. Lastly, the risk premium is the premium associated with the special risks of a given investment. In other words, is the risk you take on an investment worth the reward? The risk relates to a firm’s inability to meet its debt obligations as they come due. For example, bonds possess a contractual obligation for the firm to pay interest to bondholders; they are considered less risky that common stock where no such obligation occurs. Treasury Bonds are backed by the â€Å"full faith and credit†of the U.S. government, whereas stocks are not. If you earn a risk free return from bonds at 3%, that becomes your baseline. Now, if any investment with risk must return more than 5%. The amount the investment returns over 3%is known as the risk premium. For example, if you are looking at a stock with an expected return of 12%, the risk premium is 9%.

Endocrinology Essay Example | Topics and Well Written Essays - 1000 words
Endocrinology - Essay Example These are synthesized in the same cells. However, once secreted they interact with four adrenergic receptors such as 1, 2, 1, 2, and 3 that mediate the cellular effects of the hormones. Stress the predominant stimulus that leads to secretion of these hormones. More accurately stimuli such as injury, anger, pain, cold, strenuous exercise, and hypoglycemia as a result of stress response generate sympathetic impulses in the cholinergic preganglionic fibers that provides the neural impetus to the chromaffin cells, and this ultimately culminates into the release of catecholamines. Biochemically, however, catecholamines stimulate glucose production in the liver, lipolysis in the adipose tissue, and promotes anaerobic metabolism in the muscles leading to lactate production. Whereas, the adrenal medulla responds to predominantly neural stimuli, the outer adrenal cortex that literally encapsulates the medulla and forms the bulk of the gland, responds only to endocrine stimulation and releases a number of hormones which have steroid structures chemically. These hormones are glucocorticoids, aldosterone, and adrenal androgens. The cells of the three zones secrete different steroid hormones: the cells of the zona glomerulosa secrete the mineralocorticoids; those of the zona fasciculata secrete glucocorticoids, while the cells of the zona reticularis secrete sex steroids or androgens (Brook, C., and Marshall, N. 2001). Figure 1: Adrenal Cortex and Medulla Adrenal Cortex: Glucocorticoids act to counteract many effects of stress throughout the body. Stress is difficult to define, but it is known that it includes physical trauma, intense heat or cold, infections, mental or emotional trauma. The effects of glucocorticoids at the tissue level in order to neutralize the effects of stress include cardiovascular, neurological, and anti-inflammatory effects as well as effects on the immune system. Cortisol level responds within minutes to stress, whether it is physical such as trauma, surgery, or exercise; psychological such as anxiety and depression, or physiological hypoglycaemia or fever. The protective effect that glucocorticoids confer at the time of stress would be evident in the observed fact that such stresses may cause hypotension, shock, and death when there is glucocorticoid deficiency. The overall actions of glucocorticoids are directed at enhancing the production of glucose that can be readily utilised in the body to produce energ y and at the same time they reduce all other metabolic activities not directly involved in that process. Physiologic effects of glucocorticoids include regulation of protein, carbohydrate, lipid, and nucleic acid metabolism. These antagonize the secretion and action of insulin and raise blood sugar levels. At the same time, these also inhibit peripheral glucose uptake. This promotes hepatic glycogen content through hepatic glucose synthesis or gluconeogenesis (Berg, J.M., Tymoczko, J.L., and Stryer, L., 2002). Taking the example of exercise as a stress initiating event, as the epinephrine and nor epinephrine are released as a sympathetic response, the concomitant glucocorticoid release makes sure that the increased metabolic rate of exercise can
