Gentlemen, Choose Your Weapons

Gentlemen, Choose Your Weapons Gentlemen, Choose Your Weapons Gentlemen, Choose Your Weapons By Hugh Ashton Writing tools can affect your style. In the days of quill and dip pens, the length of sentences (or at least, phrases) was apparently determined by the amount of ink held by the pen, and prose rhythm was dictated by this simple physical constraint. Fountain pens extended the scope of the writer. No longer did (s)he have to pause in the composition of the sentence, reach over to the inkwell and use those few seconds to determine what to write next. Sentences could flow for ever, like those of Henry James. But even with a fountain pen, revisions don’t come easily. In Lamb House, Rye, where James lived for many years, some galley proofs of his works are on display, covered with major handwritten amendments. Whole paragraphs deleted and added, sentences turned on their heads, etc. No publisher today, even with modern technology, would accept such major revisions to a book at galley stage. It would appear, though, that typesetting really does crystallize a writer’s thoughts, and give a firm foundation for the next stage in the writing process. Of course, many authors used typewriters when they became available. Mark Twain, a neophile and early adopter, wrote: The machine has several virtues. I believe it will print faster than I can write. One may lean back in his chair work it. It piles an awful stack of words on one page. It don’t muss things or scatter ink blots around. Of course it saves paper. And as someone who grew up doing a lot of writing (books, articles, etc.) on a typewriter (manual Olivetti portable, and later an electric Facit golfball), I have to agree with Samuel Clemens. Mind you, corrections were tricky. I used a lot of correction fluid and paper, and rewriting a whole sentence often meant starting again from scratch on a new page. The sheer drudgery and physical labor involved in hitting typewriter keys (less with electric than a manual, of course) meant you had to think carefully about what you wrote. Planning a whole page in advance (or at least a paragraph) wasn’t uncommon. Certainly you tended to write a sentence before putting it down on paper, because it was too much trouble to recast it once it had been typed. Of course, all this refers to the first draft. Creating a second draft was often a question of starting again from scratch, or a literal â€Å"cut and paste† job. Another way of writing books was (still is for some) dictation to a shorthand secretary or a dictation machine. Dictation can produce long flowing streams of consciousness, poor style, and very clumsy or sloppy plotting in the worst cases, not to mention novels that are parodies of the author’s own style. But then came word-processors. But that’s for another week. In the meantime, your exercise for the week is to look at some older pieces of writing, and see if you can reconstruct how the authors got the words out of their heads onto paper.

Givenchy Essay Example | Topics and Well Written Essays - 2000 words

Givenchy - Essay Example Explain 6 pictures, use 4 books and 4 websites as references/sources. I. Introduction (250 words) Hubert de Givenchy was a designer in the mid-20th century who began the famous House of Givenchy. Givenchy was the driving force behind a majority of the wardrobe of Audrey Hepburn, an actress who became a major film star with the blockbuster movie Breakfast at Tiffany’s. â€Å"Hubert†¦[was] a brilliant young designer (twenty-six to Audrey [Hepburn’s] twenty-four)[,] who had worked under de Segonzac at Schiaparelli before leaving in December of 1951†¦Ã¢â‚¬  (Wasson, 2010, pp. 38). He got his start in designing clothes that were elegant and fashionable—yet practical for the modern woman of his day. Some years later, Riccardo Tisci would take over his fashion empire in 2005, bringing to the House of Givenchy a drastically different style and taking the company in a new artistic direction. Known for his bold use of dark colors—especially black— Tisci took his knowledge of Givenchy’s style and put his own unique spin on that staple of the fashion industry. Here three samples from Givenchy’s work himself—as well as Tisci’s work—will be examined. It was attempted to match sample garments that, at least indirectly, resembled each other. These pieces will be analyzed in detail. The first piece is a plain black dress; the second piece is an overcoat; and the third piece is a coat. Each piece will be compared and contrasted and thoroughly analyzed in order to see what drove and drives each of these artists (Hubert and Riccardo) respectively. Finally, conclusions will be made regarding both of the artists. II. How the Socio-Cultural Environment Led to Different Artistic Interpretations (250 words) Courtesy: Rosenwald, 2011, pp. 1. In this first piece we see by Givenchy, this is a scene with Audrey Hepburn in an orange pea coat. It reminds one of the pea coats that were typical in the 1950s and 19 60s, similar to something that Jackie O might have warn. Jackie Kennedy, by the way, was also another popular devotee of Givenchy, having had many—if not a majority—of her wardrobes designed by him. Obviously, the length of this coat, and the bright color, catches one’s eye and draws one into the wearer’s visual field. Notice the high neckline, the fuzziness of the pea coat softening the appearance of Hepburn’s face. With a stunning hat, Givenchy accentuates Hepburn’s sophisticated look. Courtesy: â€Å"Paris, Feb. 28th, 2007,† 2007, pp. 1. Riccardo Tisci, as the 21st-century lead designer at House of Givenchy, came out with the Japanese mariner-style coat, pictured above, for the 2007 fashion line. Obviously not a pea coat, this style takes a page from a different culture’s playbook of an era and co-opts it in order to make a fashion statement. The industrial look is now ‘in.’ Tisci has this model dressed entirely head-to-toe in black. Strikingly sleek and visually interesting, this jacket has a short, clean cut with a lapel. The neckline is not raised at all, and this jacket is rather form-fitting instead of Givenchy’s more bulky pea coat. This highlights the 21st-century necessity for streamlined lines and utilitarianism. Any kind of frivolous use of space in the design is now wasteless, whereas it used to be fun to have features on a garment piece that were not necessarily utility features. Now, everyone is

Interview with policy marker Essay Example | Topics and Well Written Essays - 1000 words

Interview with policy marker - Essay Example Such patients have to be making about 1800/year, and be diagnosed with mental disability. Income is all the same the major factor as they have to be making 1800/year According to the Healthy People 2020 report, one of the main aims is to reduce the homeless people. How does your facility do to ensure the same? The homeless patients are kept in boarding homes, or in other shelters How do the boarding homes, halfway homes, or shelters help in maintaining the individuals’ stability? Patients in these homes have access to continued care, they are seen by a psychiatrist on weekly basis who are paid by the government. This is in accordance with objectives the Healthy People 2020 program that aims at increasing medical practitioners contact with patients. According to you, what is the main drawback preventing your clients from receiving care? And what role should the government play in increasing the care given to your clients, as outlined under the Access to health services Objectiv e in the Healthy People 2020 project? Sometimes it gets frustrating to give essential care and shelter to a patient with no insurance cover. Funding becomes the biggest drawback; this patient population is mostly ignored due to mental illness. Therefore, shelters have serious limitations in receiving and caring for fixed number of patients according to availability of funds in issues related to behavioral health. In an epidemiology study carried out by Pratt (2012), data from a 2007 National Health Interview survey of 23, 393 adults indicated that 35% of adults with a history of mental illness had a history of homelessness. Do you believe this is a reality? And what can be done to reduce this problem? The future of the homeless depends on the ability of the government to offer more funding. The homes carry out a census of the homeless at the beginning of each year, aimed at determining funds required to assist each of the homeless. The problem is that the shelters are greatly underf unded, which is major challenge. One of the legal implications in accessing health care services is the requirement that Insurance coverage is the principal means of measuring whether one gets adequate access to healthcare among the general population, limiting the chances of the above mentally ill patients, who are usually unemployed to obtain such important services (Healthy People 2020). 2. Policy Maker Question Asked Response obtained Eno- Obong E. Senior case manager with VA community based care These questions focused on the objectives of Healthy People 2010 to improve access to community based education programs in aiding to reduce hospitalization and management of chronic diseases. 1. 1 Health is more influences away from the facility where most of the population spends most of their time. As a case manager working for the patients in the community is this statement true? I concur with this statement from my experience in the field. Before, we recorded much higher emergency visits even after implementing the home health nurse program. However, with no education on how to manage chronic diseases and access to community resources, patients still continued to be sick. The facility therefore helped in exacerbation on the long term health needs of patients accessing such community health based resources. What is the most critical service that you give to the community to reduce emergency visits, and ensuring increasing access to

The dramatic events and language of Romeo and Juliet Essay Example for Free

The dramatic events and language of Romeo and Juliet Essay Love and hate both occur many times during the course of the play, love and hate could be addressed as the two main focuses from the play. The play, Romeo and Juliet, is a tragedy but it still could be said that love triumphs over hate by the end of the play. The final scene of the play ends with Romeo killing himself when he finds out Juliet is dead and Juliet waking from sleep and finding Romeo dead. The two families, Montagues and Capulets, then put an end to their long reigning feud. This is when it could be said that love conquers hate, however this could also be viewed as a hollow victory, this describes that although the feud has been put to an end many lives have been lost in the process, including: Romeo, Juliet, Mercutio, Tybalt and Paris. When Juliet and Paris are found dead that is when the first signs of caring between the two feuding families start to emerge, unfortunately for the two families and the whole of Verona they realise that the feud was pointless after so many lives have been lost and even their own children having died. Between the Montagues and Capulets an ancient grudge exists, the prologue from the play tells us a summary of the events that happen within the play a pair of star-crossed lovers take their life, how long the play is is now the two hours traffic of our stage. The prologue also tells us things like where the play is set In fair Verona and how long the play will be Is now the two hours traffic of our stage. The prologue and act 1 scene 1 tells us who the feud is between, the two rival families the Capulets and the Montagues, however between the prologue and act 1 scene 1 the play still fails to tell us why the two families hate each other. In act one scene one the fight between the two Capulet servants and the Montague servants is started even by the two sides seeing each other, this demonstrates how seriously the feud is taken between the two families, not only do the masters of the Capulets and Montagues fight between each other but the feud even extends to the servants of each family. Although the fight is implied that it will start when the servants of the two families see each other it in fact begins when the servants from each family insult each other Nay, as they dare. I will bite my thumb at them, which is disgrace to them if they bear it. The main individual characters within the play act differently towards the feud and how it is dealt with. Tybalt is known as the prince of cats for his swordsmanship, Tybalts lust for fighting and victory over the Montagues fuels the feud a great deal. As it is seen when Tybalt kills Mercutio, Romeo then takes his revenge on Tybalt by killing him, this again fuels the feud. Tybalts attitude is more warlike than many other characters, he tries to start fights rather than attempting to stop them, which is more like Benvolio attempts to do. Capulet is another character who alongside Tybalt, can be seen as trying to keep the feud going until the Capulet family wins. He usually is not involved within the actual fights but tries to show his youthfulness by appearing like he would like to fight alongside the rest of his family members. He doesnt appear to actively encourage the fighting in the feud like Tybalt does, however he does seem to enjoy the fighting that occurs from the feud right up until the end of the play, after Romeo and Juliet die. Montagues character is more neutral, he wants the Montague family to win the feud however he doesnt encourage the fighting, he seems to want a peace more than a war between each family although he would like to see this peace at the hands of a Montague victory. Benvolio is seen within the play as a peacemaker, early on during the play Benvolio attempts to stop a fight between the two war waging families, although he successfully does this later on he appears to not be as successful. The Prince acts as the main peacemaker of the play Will they not hear? What ho, you men, you beasts! That quench the fire of your pernicious rage with purple fountains issuing from your veins. Later on during the play the Prince becomes more forceful at attempting to stop the feud; firstly he threatens to end the life of those who disobey his command to stop the feud whilst secondly he banishes Romeo from Verona to Mantua. The Princes attitude towards the feud can therefore be summarised by saying that he is wholeheartedly against the fighting that the feud produces and the feud itself, we can assume this from the punishments he threatens, the punishments he gives and the way in which he speaks about his negative view on the feud.

The Corrruption Of Innocence :: essays research papers

The Corruption of Innocence   Ã‚  Ã‚  Ã‚  Ã‚  It has struck some leaving a lasting impact while others just let it go by. Some would see it as corruption, and others see everyday life. I see it as the pure loss of innocence in a world of corruption. This new issue has risen in today's generation leaving no one free of it wrath. This has not been the first we have seen of this. The loss of innocence has been referred to over years by many authors, but now we come to see it in our lives a lot more frequently. According to authors like Emerson and Salinger, who although wrote their pieces so far apart, feel everyday in life the American Character is faced upon with the corruption of innocence that takes away from their unique American Character.   Ã‚  Ã‚  Ã‚  Ã‚  In his book, The Catcher in the Rye, J.D. Salinger focuses on the theme of innocence for a large amount of time. Holden constantly refers to everyone as being a phony and that they had lost their innocence, which had been corrupted when they matured and were exposed to society. The society had exposed them to the real world and made them think in order to survive they must follow others. Holden goes in part of the book about jobs he likes and starts to describe job of a lawyer and says how they are sincere and try to save innocent lives, but then he goes on to think about how they are probably phonies and only doing it to be hot-shots and makes lots of money to impress society. (Salinger 172) The outcome of his thoughts was that everybody had conformed and followed each society's ideas, which upset Holden because no one was free of corruption accept the children of society, like Ally. Holden sees it as a major issue in the book and serves as a major role of Holden 's throughout the book. The issue even leads to the title of the book in the sense that it is named after his supposed job he wishes to under take as a Catcher in the Rye. He wants to be a catcher in a field of rye and little children who catches children from falling off the cliff and being corrupted by society. (Salinger 173) Therefore, in fact the theme of innocence has a significant role in this book.   Ã‚  Ã‚  Ã‚  Ã‚  Another author who also uses the role of innocence and corruption as a major theme is Ralph Waldo Emerson in his essay 'Self-Reliance';.

Ethical Healthcare Issues

Running Head: ETHICAL HEALTHCARE Ethical Healthcare Issues Paper Wanda Douglas Health Law and Ethics/HCS 545 October 17, 2011 Nancy Moody Ethical Healthcare Issues Paper In today’s health care industry providing quality patient care and avoiding harm are the foundations of ethical practices. However, many health care professionals are not meeting the guidelines or expectations of the American College of Healthcare Executives (ACHE) or obeying the organizations code of ethics policies, especially with the use of electronic medical records (EMR). Many patients fear that their personal health information (PHI) will be disclosed by hackers or unauthorized users. According to Carel (2010) â€Å"ethical concerns shroud the proposal in skepticism, most notably privacy. At the most fundamental level, issues arise about the sheer number of people who will have ready access to the health information of a vast patient population, as well as about unauthorized access via hacking. †Ã‚  This paper will apply the four principles of ethics to EMR system. EMR History Pickerton (2005), â€Å"In the 1960s, a physician named Lawrence L. Weed first described the concept of computerized or medical records. Weed described a system to automate and recognize patient medical records to enhance their utilization and thereby lead to improved patient care† (para 1). The advantages of EMR system includes shared information integrated information, improvement of quality care, and adaptation of regulatory changes. Even though EMR systems have many advantages, EMR systems also have some disadvantages too. Some disadvantages of EMR systems are security, and confidential, which can raise ethical issues. In order to help identify and vercome ethical issues with EMR systems, health care professionals can use the four principles of ethics to help identify where ethical issues are compromised. The four principles of ethics are autonomy, beneficence, nonmaleficence, and justice. Autonomy According to Mercuri (2010) â€Å"autonomy means allowing individuals make their own choices and develop their own lives in the context of a pa rticular society and in dialogue with that society; negatively, autonomy means that one human person, precisely as a human person, does not have authority and should not have power over another human person† (para 2). Autonomy has an effect with ethics concerning EMR systems because health care organizations should have an EMR system that should maintain respect for patient autonomy. Respect for patient autonomy should have health care organizations to make decisions concerning user access of the records. Access of Records Before a health care organization implements an EMR system, they should have a security system in place, which includes â€Å"access control† component. Access control within an EMR system is controlled by distinct user roles and access levels, the enforcement of strong login passwords, severe user verification/authorization and user inactivity locks. Health care of professionals regardless of their level, each have specific permissions for accessing data. Even though the organization have the right security system in place to prevent unauthorized users from access patient records, autonomous patients will expect to have access to his or her records with ease. Access their record will ensure that their information is correct and safe. Beneficence According to Kennedy (2004) â€Å"beneficence is acting to prevent evil or harm, to protect and defend the rights of others to do or promote good† (p. 501). Beneficence has an effect with ethics when it comes to EMR systems because health care professionals can help to improve the health of individual patients by using patient records to help with medical research. EMR systems contain an enormous amount of raw data, which can innovate public health and biomedical research. This research will not only do good to help the health of individual patients, but also to the health of society (Mercuri, 2010). As a result, as new EMR systems are designed, patients should be given the ability to release information from their EMRs to researchers and scientists. Nonmaleficence Not only does beneficence have an effect with ethics concerning EMR systems, but also nonmaleficence. According to Taber’s Cyclopedic Medical Dictionary â€Å"The principle of not doing something that causes harm. Hippocrates felt this was the underpinning of all medical practice. He advised his students,  primum non nocere  (â€Å"first, do no harm†)† (â€Å"Nonmaleficence,† 2010). Nonmaleficence has an effect with ethics concerning EMR systems because it is the employee’s responsibilities to report any negligence or fraud of patient medical records. However, if an employee doesn’t report negligence or fraud it will cause harm to the organization and to the patient. Reporting negligence will make the organization aware of the problem and help them find a solution. Employees can help prevent negligence or fraud notifying management when a problem is discovered. Employees can also help prevent negligence or fraud by making sure that their system access information is secure. In addition, employees can also help prevent negligence or fraud by making sure that they are creating accurate records. If the employees follow these policies of EMR security systems, they will ensure that the patient medical records are secure and safe from harm. Justice Not only does nonmaleficence have an effect with ethics when it comes to EMR systems, but also justice. According to Mercuri (2010) â€Å"justice is commonly defined as fairness. With respect to health care, justice refers to society’s duty to provide its members with access to an adequate level of health care that fulfills basic needs† (para 5). Justice has an effect with ethics concerning EMR systems because EMRs are most helpful when the system is easy to use, fully integrated, and easily searchable. EMR systems have the potential to assist health care organizations by providing higher quality care to the users and to the patients. In addition, EMR systems also assist health care organizations by having a system that is more unbiased through advanced effectiveness. Conclusion Even though there are still some ethical issues with EMR systems, health care professionals are moving in the right direction by being more aware. Health care professional want to do the right thing by following the organizations code of ethics, but sometimes they are not always clear on how they should handle certain EMR systems situations properly. In order for health care professionals to handle certain EMR systems situations properly, they can use the ACHE as a reference. Using ACHE as a reference ensures that they are meeting ACHE standards. Health care professionals can also apply the four principles of ethics to determine a resolution. Applying the four principles of ethics ensures that they are following the proper protocols and guidelines and leaves considerable room for judgment in certain cases. Reference Carel, D.

Market Equilibration Process Paper

Market Equilibration Process ECO / 561 Market Equilibration Process Market Equilibrium occurs when the quantity supplied is equal to quantity demanded. The price equilibrium price exists when buyers and sellers price match and there is no governmental intervention (perfectly competitive market). After a market is in equilibrium, there is no trend for the market price to alter. For example, the law of demand states that as price goes up the quantity demand must go down and similarly, law of supply states price goes up quantity supply must go up (McConnel, Brue, & Flynn, 2009). Viewing the graph below we can find the equilibrium occur at the price of $3 where the quantity demanded equals the quantity supply at three units. The price is stable at $3 and at any other prices will have a |Price (P) |Quantity Demanded (Qd) |Quantity Supplied (Qs) | |$1 |5 |1 | |$2 |4 |2 | |$3 |3 |3 | |$4 |2 |4 | |$5 |1 |5 | Equilibrium occurs at P=$3 (Qs = Qd = 3 units) [pic] a tendency to change. At a dollor, for example, at $1 buyers are able to buy five units but seller are only willing to provide one unit to the market. In this situation, quanitity damand is greater than qualiity supply is referred to as a shortage and will result in an upward pressure in price. Since there is only one unit is available so buyers will complete to buy the one available unit by offering more money. Then price goes up and the qualitity demand decreases, quantity supply rises until equilibrium is reached (McConnel, Brue, & Flynn, 2009). pic] Disequilibrium Disequilibrium occurs when the price or quantity is not equal to Price or Quantity. If the prices are high, surplus is created and there will be inefficiency. Demand surplus is created when prices are below the equilibrium price. Since the prices are low, many buyers want the good while suppliers are not making enough of it. A shift in a demand or supply curve occurs when the good’s quantity demanded or supplied changes but the price remains the same. Short-run and Long-run Supervalu is going through a long-run, which is a period when a plant or company has a long period to adjust the quantities of all the resources that it employs. I currently work for Supervalu and its dissolving certain retail stores such as Acme Markets because it is not producing profits in a certain metropolitan markets. Acme Markets price was below the minimum average variable cost and to minimize its losses, Supervalu shut down the retail stores. New retail markets such as Save-a-Lot stores are increasing because it targets at low-medium level income families. Pure Competition Supervalu is part of the pure competition because its retail stores are offering standardized products. Supervalu retail stores are able to freely enter and exit the industry. In pure competition, marginal revenue and price are equal (McConnel, Brue, & Flynn, 2009). Reference McConnel, C. R. , Brue, S. L. , & Flynn, S. M. (2009).

How to Clear Your Mind - Unclog Your Brain - Relax

How to Clear Your Mind - Unclog Your Brain - Relax Sometimes we can get so caught up in the stress and worry of our personal lives that our minds become too jumbled to operate effectively. This is especially dangerous in a test-taking situation. After hours of reading and studying, our brains can lock up in a state of overload. In a stressful situation, it’s often necessary to clear your mind completely to allow your brain to refresh itself and recalibrate all of  its functions. But when you’re tense, clearing your mind isn’t so easy! Try this relaxation technique if you think your brain has seized up from information overload. 1. Set aside at least five minutes for quiet â€Å"clearing† time If youre at school, see if you can put your head down somewhere or find an empty room or quiet space.  If necessary, set a watch (or phone) alarm or ask a friend to tap you on the shoulder at a designated time. 2. Think of a time or place that puts you into a complete state of peace This place will be different for different people. Have you ever sat on the beach watching the waves come in and realized you’ve â€Å"zoned out† for awhile? This is the sort of experience you’re looking for. Other experiences that make us zone out could be: Sitting in the dark and staring at Christmas tree lights- remember how quiet and peaceful that feels?Lying in bed late at night listening to good musicLying on your back on a cool day watching clouds roll by 3. Cover your eyes and go to your â€Å"place† ​ If you are at school preparing for a test before class, you may simply rest your elbows on the desk and put your hands over your eyes. For some people, it may not be a good idea to put your head down. (You might fall asleep!) Use all your senses to make your experience as real as possible. If you are thinking of a Christmas tree, imagine the smell of the tree and the look of the layered shadows on the walls. Don’t let any thoughts creep into your head. As soon as you start to think about a test problem, clear away the thought and concentrate on your peaceful place. 4. Snap out of it! Remember, this is not nap time. The point here is to rejuvenate your brain. After five or ten minutes of clearing time, take a brisk walk or take a drink of water to re-energize your mind and body. Stay relaxed and resist the urge to think about the things that are stressing you out or clogging your brain. Don’t let your brain go back to freeze-out. Now go forward with your test or study session refreshed and ready!

The 11 Best GED Practice Tests to Help You Prepare

The 11 Best GED Practice Tests to Help You Prepare SAT / ACT Prep Online Guides and Tips Having your GED can open many doors for you, including getting a better job or being able to attend college, so you want to give yourself the best shot at getting a passing score. For most people, this means they’ll need to spend some serious time studying for the GED, and one of the best ways to prepare is to take GED practice tests. This guide contains all the best practice GED tests available, including official, free, and paid practice tests. We explain where to find them, how much they cost, what each test’s pros and cons are, and we also give general advice on what to look for in a GED practice test. What Makes a Good GED Practice Test? GED practice tests give you a feel for the test, help you learn what topics you’ll be tested on, and find out how much studying you need to do to pass. However, not all practice tests are high quality, and taking a poorly-designed GED practice test can actually end up lowering your score because you’ll study the wrong topics and possible neglect areas you should be studying. Additionally, because the GED was recently updated in 2019, outdated practice tests can also cause you to study the wrong information. The best practice GED tests are those that are closest to the actual GED in terms of length, format, difficulty, and the material they test. When you take a high-quality GED practice test, you’ll get a feel for how quickly you should answer questions to finish the section in time, which subjects you struggle with and need to practice, how the GED words questions, and how well you’re scoring on each section overall. You can then take this information and use it to develop a study plan that focuses on building up your weaknesses so you can pass each section of the GED. The GED consists of four sections, and you need to pass all four sections (though not all at the same time) to get your GED. The test is taken on the computer, and each section has a specific time length: Mathematics: 115 minutes Social Studies: 90 minutes Science: 90 minutes Reasoning Through Language Arts: 150 minutes (including a 10-minute break) In the rest of this article we go over different options you have for GED practice tests. As an overall plan, we recommend taking an official GED practice test for at least the sections you’re struggling the most on, purchasing a prep book to give yourself more high-quality practice tests, and supplementing with free GED practice tests to get more practice in any weak areas you still have remaining. Where to Find Official GED Practice Tests If you can afford to purchase official GED practice tests, we highly recommend that you do. Official practice tests are made by the same people who make the actual GED. This makes them the gold standard because you can be sure they will match the format, content, and difficulty of the actual GED. GED Ready sells official GED practice tests, and they cost $6 per subject. If you were to purchase a practice test for each of the four sections, that would cost you a total of $24.The practice tests are computer-based, and after you complete each section, you’ll receive your results and information on how likely you are to pass that section. These are high-quality practice questions that will give you a great feel for the real GED, but there are some drawbacks. First, each section is only half as long as it will be on the actual GED, which gives you less practice and doesn’t allow you to learn how well you’ll hold up during a longer test. Next, you can only take each practice test once. You can purchase multiple practice tests for each GED subject, but that can get expensive quickly, so you really need to make the most out of the one time you can take each practice test. You can also purchase official flashcards with practice questions on them. These aren’t quite as good a study tool as practice tests, especially if you only study a few at a time, because they don’t give you the same experience of taking a full-length test. However, they are a good resource if you want additional study practice (although they likely contain many of the same questions the practice tests do, so we don’t recommend purchasing both). There are thousands of flashcards for each GED subject, and it costs $15 for 30 days worth of access per subject. Where to Find the Best Paid GED Practice Tests After the official GED practice tests, these are the best resources to use because they are still a close match to the actual GED in terms of format and quality of the questions. The best paid GED practice tests come from prep books that can be purchased as a physical book or an ebook. Below are the three best GED prep books available. Kaplan GED Test Prep Plus Price: About $20 If you only want to pay for one set of GED practice tests, we recommend you purchase the Kaplan prep book. It’s not an official source, but Kaplan works with the official makers of the GED to create very realistic practice tests. These practice tests are second only to official prep materials in terms of quality. This GED prep book comes with two full-length practice tests (one in the book and one online), over 1,000 practice questions, and written and video lessons. Two practice tests isn’t a huge amount, and some resources offer more, but the materials that you get with this book are high quality, and it’s a good overall resource for people looking for the whole study package: lessons, practice questions, and complete exams. Test Prep Books: GED Preparation Price: About $18 For those looking for a GED practice test with more explanation on how to solve tricky questions, the GED Preparation book by Test Prep Books may be the choice for you. It only includes one full-length practice test, but it has in-depth explanations for all the questions, as well as explanations for all the topics you need to know for the exam. If you’re struggling to raise your score, you can use this book to learn the material you need, then take the test it includes to see how much you’ve improved (although you’ll likely need to take additional practice tests from other sources to get enough practice in). Princeton Review: 5 Practice Exams for the GED Price: About $15 Princeton Review offers a GED prep book which contains five practice exams and over 800 practice questions. This is great if you’re looking for a lot of GED practice, but they aren’t quite as good a resource as the official or Kaplan practice tests. Some of the practice tests are shorter than the actual GED tests, which can make it difficult to figure out if you’re answering questions quickly enough to finish the test in time. Others mentioned that these practice questions are harder than the actual GED, so they ended up studying topics they didn’t need to know. If you’re looking for a lot of practice, this book can be useful, but make sure you’re aware of its shortcomings. Where to Find the Best Free GED Practice Tests While there are some good free GED practice tests available, none of them are awesome, so we highly recommend paying for at least one practice test so you know what a high-quality practice GED looks like. Free GED practice tests range from good to pretty bad, so be careful which free resources you use. Many aren’t updated for the newest version of the exam, some don’t have the same format as the actual GED, and some don’t test the same topics or have the same level of difficulty as the GED. In this section, we go over all the best free GED practice tests that are available. Be aware that, for all free GED practice tests, none are as long as the actual GED, and many are quite a bit shorter, so you can’t use them to get practice taking a full-length practice test. Test Prep Toolkit This is one of the better free GED practice tests available. It’s updated for 2019, is fairly long (though not as long as the actual GED), and has in-depth answer explanations. There are about 25 questions per section, which isn’t as much practice as some of the sites that offer 100s of questions, but they’re a close match to what you’ll see on the GED. Union Test Prep This is a solid practice test with questions that are similar to what you’ll see on the GED. A drawback is that it has some formatting differences compared to the actual test, and you’ll see if you got the question right immediately after you answer it, instead of waiting until the end of the section like the real GED. Also, the test isn’t timed, so if you’re working to improve your timing, you’ll need to use additional GED practice tests. Test Guide These practice tests are significantly shorter than the actual GED, making them more like practice quizzes, but they are fully updated and are similar to actual GED questions. There are multiple tests for each section of the test, and the site also includes answer explanations and information about the format of the GED. GED Practice Questions Similar to the Test Guide resources, this site includes numerous short practice tests for each section of the GED. The practice tests are each significantly shorter than the actual GED so you can’t use this site to practice the GED’s format, but it’s another source of good practice questions. GED Practice Test 2019 Edition (App) This highly-rated Android app includes over 1,000 practice questions you can study with. The questions include in-depth answer explanations, and the app automatically stores all the questions you get wrong in a challenge bank so you can try them again. You can also set score goals and get notifications when you meet them. The major drawback of this app is that it doesn’t use the same format as the actual GED does, so it’s better for shorter study sessions compared to taking it as a full-length test. Mometrix Mometrix includes a practice test for each of the GED sections. The practice test is fairly short, about 15 questions in each section, but the questions are high-quality, so it makes a good resource if you need a bit of additional GED practice. Varsity Tutors Varsity Tutors has dozens of GED practice quizzes. Most of these quizzes are quite short, some just a few questions long, but they are broken into specific categories which can be useful if you’re looking to target your studying. For example, the GED Math practice tests are broken into categories such as linear algebra, finding slope, and circles. There are also longer GED diagnostic tests for the Math, Social Studies, and Language Arts sections. Summary: GED Practice Tests If you’re studying for the GED, you absolutely need to take practice tests to make sure you’re on track to pass each section of the exam. Practice tests are great because they give you a feel for the GED and let you know which areas you still need to improve in. The absolute best practice tests are official practice tests because you can be sure they’ll match the real GED, but there are also unofficial options (both paid and free) available). What's Next?

Religion Assignment Example | Topics and Well Written Essays - 250 words - 1

Religion - Assignment Example The epic â€Å"Book of Gilgamesh† was used to influence other people to magnify the king’s power. In fact, the real king Gilgamesh was worshipped after his death because of this book’s influence ( the house of royalty.nu,2010). Historically, a kingdom’s influence (during such civilization) is based on its religion. An example of a similar civilization is that of Egypt where people perceive the Pharaoh as a god. Hence, respect is immense for the said leader. â€Å"Astrologys ancient beginnings are also traced to Mesopotamia at least as far back as 2001 BCE. These early records reveal a complex cosmology in which the Sun, the Moon and the planets represented gods who possessed the power to direct and intervene in the course of physical events† ( metareligion.com) In fact, many people read the horoscope in newspapers scouring for any prediction about their future. This influence was ushered by the coming of New Age religion. In conclusion, old civilizations like Mesopotamia has highly-influenced religious beliefs which has permeated even modern -day societies

Sustainability of Seventeen Event Company Essay - 1

Sustainability of Seventeen Event Company - Essay Example As a concept, Sustainability can be defined as the â€Å"the growing concern for the environment and natural resources, though...[it]...has also had increasing resonance in social and economic issues.† (Mowforth and Munt,2009, p18). Academic, political and economic circles have begun to seriously consider the implications of unrestricted economic growth on the already stretched resources of the earth. The agenda is motivated by the understanding that the planet may not be able to cope up with the demands of the growth unless drastic measures are taken to support the processes with more environmentally friendly practices and technology. The burden of change in this area falls largely to businesses and economic groups as they are the main consumers of many of the natural, human and financial capital resources available currently. While governments and lobbying groups can provide much-needed direction and policies to guide the businesses towards sustainable practices; inevitably it is the businesses themselves that must show awareness and concern regarding the issue and make changes from the ground level as they have a greater reach and influence than any single consumer possibly could have.   It is not surprising that societal expectations from both local and international stakeholder are now forcing businesses towards a higher level of accountability and transparency with regards to not just their financial performance but also their role as a social participant in economic, social and environmental development (Sherwood, 2007). While responses have varied, businesses, especially in the consumer-centric, western markets, have responded to these responsibilities with efforts to be operationally eco-efficient, and incorporate social responsibility into their overall operations.
