Juwon Hill Personal statement for Graduate Economics MA Personal Statement

Essays on Juwon Hill Personal statement for Graduate Economics MA Personal Statement Personal ment I am Juwon Hill. I expect to graduate this May with a degree in Bachelor of Arts in Business Administration major in Economics from the Morehouse College in Atlanta, Georgia. I would like to seek professional advancement by enrolling in the Graduate Program in Economics at the University of Colorado Denver. Pursuing a Masteral Degree in Economics will give me the opportunity to learn more about economics and its application in the business world. With the trend towards globalization, I am convinced that a career in Economics will prepare me for a brighter future. I will better understand the various economic policies of the different governments. I believe that it will open up opportunities for research while working with a diverse group of people within the University. After graduation from the program, my career prospects will be wider and better. Another reason why I chose the University of Colorado is because of its perfect location, being in the middle of a beautiful city. I know I will have an enjoyable time studying in the University. During my school days at Morehouse, aside from excelling in academics, I was active in extra-curricular activities. I was part of several student organizations which honed my talents and skills. These activities have made me a well-rounded student. My college career has been a learning experience. I faced many challenges but was able to overcome them and eventually graduate after four years. My resume shows that my work experience is quite diverse. I have worked as a Program Facilitator, Sales Associate and a Veterans Affair Representative. These jobs exposed me to various aspects of business such as sales, customer service, inventory management and administrative work. My work experience has taught me the value of hard work, patience and teamwork. I made sure that in every task that I am assigned, I always do my best. I view new and difficult jobs assigned to me as a challenge to improve my skills. Through my work experience, I met people of different nationalities; thus, it made me more culturally aware. In the future I hope to expand my overall understanding of economics. After the Graduate Program, I foresee myself moving on to get a Doctoral Degree in Economics. I intend to combine a career in economics and sports. I also want to expand my personal network by joining school organizations and civic associations. I hope that the University will consider me eligible for your Graduate Program in Economics and look on the merits of my application. I believe that a Masteral Degree from the University of Colorado will help me in the further advancement of my professional career. In Morehouse College our motto is â€Å"Et Facta Est Lux† or translated in English, â€Å"And There Was Light†. Likewise, the motto of the University of Colorado Denver (UCD) is â€Å"Let Your Light Shine.† Whether it is coincidental or intentional, I find these two mottos related and probably an indication that I must pursue my graduate studies at UCD because it has the same vision as that of Morehouse. The transition seems to be perfect for my personal and professional growth. Hopefully, I will be able to shine after graduation at UCD and be a light for others too.

Essay on Advertisement Greek Statue and Perfume - 1462 Words

Advertisement: Greek Statue and Perfume While flipping through the pages of a fashion magazine, my fingers stop abruptly as my eyes catch an image of a nude man holding a clothed woman. The man has a muscular body and is effortlessly supporting the woman whos body is arched backwards, her arms hang in a swan-like manner. On the ground by her left foot lays a paint palette and her right hand is grasping a paint brush. The room that they are in appears to be a studio with press board floors, brick walls, and old unfinished wooden workbenches draped in cloth. The woman is painting a canvas with the image of the nude man.

The Greeks celebrated works of art and took pride in their arts ever changing forms. Most notable of Greek art forms are the architecture of temples and the realistic statues. Statues wer e initially made from marble, which was readily available in Greece. During the Archaic period of Greece (600-480 BC), statues and sculptures usually showed people standing, though sometimes portrayed figures reclining or sitting. They resembled Egyptian statues in that the figures were very straight and were rarely shown in action positions. Usually life-size or larger, these statues were meant to show the ideal body. They did not look like real people; often their hair looked wig-like and most statues were smiling closed lipped, which is known as the Archaic smile. Traditional statues of the time were mostly canon in appearance. The female statues were called korai (singular kore) and the male statues were called kouroi (singular kouros). The main difference in the way male and females were represented is in their clothes. The Archaic korai were always clothed and are thought to have represented deities, priestesses and nymphs, the young female immortals who served as attendants t o the gods. The kouroi, nearly always nude, have been variously identified as gods, warriors, and victorious athletes.

Which system, in your opinion, is the best for the United States to follow? Note: This essay is not to be a research report about socialism/communism or free enterprise. It is a persuasive essay in which you should state your opinions based upon your knowledge of both economic systems. Use proper grammar, spelling, and punctuation in your essay. Type your essay here: For the United States I would recommend the free enterprise system. If we were to have that we would be able to see the changes that it makes. With socialism it doesn’t motivate people to work hard and make a living because it is divided among the community where you live. If some people worked and others didn’t the money would still be given to the people who don’t work. We will write a custom essay sample on Socialism or Free Enterprise or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I believe that the free enterprise system would be best because it’s based on the principle of individual rights. With the free enterprise, also known as capitalism, the government has limited control over business, which lets business’ compete. It lets people choose what kind of work they want to do and where they want to work. It lets people decide what they want to do with their money if they want to put it into a retirement account or in the stock market. There are only a few disadvantages of Capitalism that I see. There are barriers between people in terms of how much wealth they have or how much money they make. Also that government control is so limited that it lets a few businesses to dominate their industry and then they become able to make the rules for their industry. I would definitely advocate the idea of capitalism over socialism any time.

Religion, The Missing Dimension Of Statecraft Essays - Peace

Religion, The Missing Dimension Of Statecraft Religion, The Missing Dimension of Statecraft Douglas Johnston and Cynthia Sampson, editors Center for Strategic and International Studies Editors: Douglas Johnston and Cynthia Sampson compiled these essays for the Center for Strategic and International Studies. Douglas Johnston has since founded the International Center for Religion and Diplomacy, with the goal of encouraging faith based mediation through education and strategy development. Cynthia Sampson is the president of Peace Discovery Initiatives, a faith-based organization with the goal of peace building around the world. Argument: The main focus of this book is to bring religion back into politics. For various reasons, the religion factor has been removed from policy making around the world, to the detriment of international relations. Johnston conveys the importance of religion when dealing with international policy, especially when one of the parties has a worldview that is deeply rooted in religion. Seven examples of how religious involvement positively affected international relations and eventually brought about reconciliation are used: the role of the Moral Re-Armament Movement in Franco-German Reconciliation, the role of religious groups, especially the Quakers, in restoring peace between the Sandinistas and the East Coast Indians, the role of the Quakers in the Nigerian civil war, the role of the churches in East Germany during the break down of the Berlin wall and the events leading up to that even, the role of the Catholic Church and the 1968 revolution in the Philippines, the role of the c hurch during apartheid in South Africa, and the role of religious actors in the transformation of Rhodesia to Zimbabwe. The main reason given for the success of religious actors in conflict resolution is their ability to gain trust and act as honest brokers between the groups involved. The Western powers cannot afford to ignore the importance of religion around the world nor can they afford to let the rare skills of relationship building brought by religious actors to go to waste. Religious groups have the desire and key qualities of trust building, patience, and unbiased involvement necessary to facilitate reconciliation and build peace around the world. These attributes are vital to reconciliation and mediation in a world where deception and diplomacy often come hand in hand. Analysis: It clear that one of the key factors of the success of religious actors (RAs) in conflict resolution is their focus on reconciliation and a true desire to be unbiased mediators. Unlike others at the proverbial table of peacebuilding, religious actors usually seek only reconciliation and peace, and not personal gain. This, along with their ability to build faithful relationships, is a vital part of their work. Many government officials have picked up on this, and have used them to carry messages between themselves and other parties involved in conflict. RAs are often referred to as honest brokers in the book; years of trust building were required to build these bonds of trust. However, this trust is invaluable when it came time to sit down and talk. Most faith-based NGOs see this as a core value of the process of reconciliation; they understand the need for a trusting relationship to be built in order to be truly reconciled. Emerging leaders should take the message of this b ook into consideration and know that in order to truly change the world reconciliation must be built on a firm foundation of trust and honesty, both of which are key elements in faith-based mediation. The subject of why religion has been taken out of contemporary diplomacy was neglected, though this information would have given the reader a firmer foundation from which to defend their argument to include religion as a factor in international policy. The book is very thorough and well thought out. Readers will become well educated about the facts and people involved in each story. A reader should be very careful not to let the endless details slow their reading but to continue to gain an understanding. The book is useful to both the reader that just wants ideas pertaining to the use of religion in international policy and the reader who is looking for specific examples to use. I found myself confused by the style of some of the authors that wrote in great detail

How to Find Your Career Type Based on Your Personality

How to Find Your Career Type Based on Your Personality Decades from now, when you’re sipping some bubbly at your retirement party, what do you want the theme of the day to be? â€Å"She didn’t hate her career all of the time†? â€Å"He broke the record for the number of career jumps in a 10-year period†? Of course not. You want that day to be a celebration of a career that was satisfying and fruitful for you. But in the meantime, how do you achieve that long-lasting career satisfaction?

If you have trouble visualizing a five-year plan for yourself, it might very well be because you’re on a career path that makes you uncomfortable. If you majored in accounting in college because it seemed like the thing to do at the time, but now you want to scream after spending hours knee-deep in spreadsheets, well†¦maybe you and accounting aren’t a good match.Figuring out your career personality can help you avoid that spreadsheet rage by narrowing down what would interest and challenge you. Maybe you and your accounting degree would be better suited to a different kind of financial environment- or maybe you should be on cable news talking about the economy. There are ways to adapt skills and interests to different career paths, but you won’t know how to take advantage of that until you take the time to figure out what you can do, and where you should be doing it.Money shouldn’t be the only career consideration.Yes, of course you want the job that pays your bills and maybe even lets you save up for that dude ranch vacation you’ve b een eyeing on Groupon.

How to Get 800 on SAT Math, by a Perfect Scorer

How to Get 800 on SAT Math, by a Perfect Scorer SAT / ACT Prep Online Guides and Tips Are you scoring in the 600-750 range on SAT Math? Do you want to raise that score as high as possible- to a perfect 800? Getting to an 800 SAT Math score isn't easy. It'll require perfection. But with hard work and my strategies below, you'll be able to do it. I've scored 800 on Math on all my SATs, and I know what it takes. Follow my advice, and you'll get a perfect score- or get very close. Brief note: This article is suited for students already scoring a 600 on SAT math or above. If you're below this range, my "How to improve your SAT Math score" article is more appropriate for you. Follow the advice in that article, then come back to this one when you've reached a 600. Overview A lot of SAT Math guides out there are pretty bad. They're written by people who don't have actual expertise in the test, or they contain vague advice that isn't helpful to the advanced student. You need better advice than simple SAT Math tips like "remember there's no guessing penalty!" In contrast, I've written what I believe to be the best guide on getting an 800 available anywhere. I have confidence that these strategies work because I used them myself to score 800 on SAT Math, every time I've taken the SAT.They've also worked for thousands of my students at PrepScholar. In this article, I'm going to discuss why scoring an 800 is a good idea, what it takes to score an 800, and then go into the 8 key SAT Math strategies so you know how to get an 800 on SAT Math. Stick with me- as an advanced student, you probably already know that scoring high is good. But it's important to know why an 800 Math score is useful, since this will fuel your motivation to get a high score. Finally, in this guide, I talk mainly about getting to a 800. But if your goal is a 700, these strategies still equally apply. Understand the Stakes: Why an 800 SAT Math? Let's make something clear: for all intents and purposes, a 1530+ on an SAT is equivalent to a perfect 1600. No top college is going to give you more credit for a 1580 than a 1540. You've already crossed their score threshold, and whether you get in now depends on the rest of your application. So if you're already scoring a 1550, don't waste your time studying trying to get a 1600. You're already set for the top colleges, and it's time to work on the rest of your application. But if you're scoring a 1520 or below AND you want to go to a top 10 college, it's worth your time to push your score up to a 1530or above. There's a big difference between a 1450 and a 1550, largely because it's easy to get a 1450 (and a lot more applicants do) and a lot harder to get a 1550. A 1530places you right around average at Harvard and Princeton, and being average is bad in terms of admissions, since the admissions rate is typically below 10%. So why get an 800 on SAT Math? Because it helps you compensate for weaknesses in other sections. By and large, schools consider your composite score moreso than your individual section scores. If you can get an 800 in SAT Math, that means you only need a 730 in SAT Reading and Writing. This gives you a lot more flexibility. MIT expects an 800 in SAT Math. There are two other scenarios where an 800 in SAT Math is really important. First is if you're planning for a quantitative or science major (like math, physics, statistics, chemistry). The second is if you're applying to a highly selective technical school like MIT or Caltech. Here's the reason: college admissions is all about comparisons between applicants. The school wants to admit the best, and you're competing with other people in the same "bucket" as you. By applying as a math/science major, you're competing against other math/science folks: people for whom SAT Math is easy. Really easy. Here are a few examples from schools. For Harvard, Princeton, MIT, Caltech, and even less selective schools like Harvey Mudd, the 75th percentile SAT Math score is an 800. That means at least 25% of all students at these schools have an 800 in SAT Math. Even more surprising: the 25th percentile score for SAT Math at MIT and Caltech are 750 and 770, respectively. This means if you score a 750 on your SAT Math, you'rewell below average for these schools! I'm not going to lie. SAT Math was super easy for me. I got 800 on pretty much every practice test and official SAT I ever took. This was largely because I had a strong math background and competed in math competitions like AMC/AIME. I also worked hard and applied the strategies below to achieve perfection. You're competing against people like me. And if you apply with a 700 on Math, schools like MIT, Harvard, and Princeton are going to doubt your ability. Because SAT Math is supposed to be trivially easy for you. But if you can work your way to an 800, you show that you're at an equal level (at least on this metric). Even if it takes you a ton of work, all that matters is the score you achieve at the end. Know That You Can Do It This isn't just some fuzzy feel-good message you see on the back of a Starbucks cup. I mean, literally, you and every other reasonably intelligent student can score an 800 on SAT Math. The reason most people don't is they don't try hard enough or they don't study the right way. Even if math wasn't your strongest suit, or you got a B+ in Calculus, you're capable of this. Because I know that more than anything else, your SAT score is a reflection ofhow hard you work and how smartly you study. Here's why: the SAT is a weird test. When you take it, don't you get the sense that the questions are nothing like what you've seen in school? It's purposely designed this way. The SAT can't test difficult concepts, because this would be unfair for students who never took AP Calculus. It can't ask you to solve Fermat's Last Theorem. The SAT is a national test, which means it needs a level playing field for all students around the country. So it HAS to test concepts that all high school students will cover. Basic algebra (solving single-variable equations, word problems), advanced algebra (quadratic and exponential equations), geometry (x-y coordinate geometry, circles squares and triangles), and basic statistics. You've learned all of this before in high school. But the SAT still has to make the test difficult to differentiate student skill levels, so it needs to test these concepts in strange ways. This trips up students who don't prepare, but it rewards students who understand the test well. Here's an example: Find the area of the shaded region below, if the radius of the circle is 5. This is a classic SAT type question. You might already know how to solve it. But it's unlikely you ever ran into something like this in school. The first time you see this, it might be confusing. How do you get the area of each of the shaded corners? It kind of looks like a triangle, but not really because of the curve region. But you've learned all the concepts you need to solve this. Notice that the shaded area is the area of the square, with the area of the circle punched out. To get to the answer quickly, this means that the area of a square is 10 x 10 = 100, and the area of a circle isÏ€r2, orÏ€ * 5 * 5 = 25Ï€. So the area of the shaded region is 100- 25Ï€. The SAT math section is full of weird examples like this, some of which get much more difficult. To improve your score, you just need to: master the types of questions that the SAT tests, like the one above draw on the correct concepts you already know to solve the questions practice on a lot of questions so you learn from your mistakes I'll go into more detail about exactly how to do this. First, let's see how many questions you need to get right an 800. What It Takes to Get An 800 in Math If we have a target score in mind, it helps to understand what you need to get that score on the actual test. There are 58 questions in the Math section, and how many questions you miss determines your scaled score out of 800. From the Official SAT Practice Tests, I've taken the raw score to scaled score conversion tables from 4 tests.(If you could use a refresher on how the SAT is scored and how raw scores are calculated, read this.) Raw Score Test 1 Test 2 Test 3 Test 4 58 800 800 800 800 57 790 790 790 800 56 780 780 780 790 55 760 770 770 790 54 750 760 750 780 53 740 750 740 770 52 730 740 730 760 51 710 730 720 750 Math has a REALLY strict grading scale. On 3 out of 4 tests, if you just miss a single question, you get dropped down to a 790. That's it- no perfect score! On one of these tests, you get an extra cushion of 1 question, but that's not much. This all depends on how the particular test you're taking is scored. The harder the math questions are, the more likely you can miss one question and get an 800. The safest thing to do is to aim for perfection. On every practice test, you need to aim for a perfect raw score for an 800. Whatever you're scoring now, take note of the difference you need to get to a 800. For example, if you're scoring a 700 now, you need to answer 8-9 more questions right to get to an 800. As a final example, here's a screenshot from my exact score report showing that I missed 0 questions and earned an 800. (This was from the previous 2400 version of the SAT.) OK- so we've covered why scoring a higher SAT math score is important, why you specifically are capable of improving your score, and the raw score you need to get to your target. Now we'll actually get into actionable strategies that you should use in your own studying to maximize your score improvement. Strategies to Get an 800 on SAT Math What's your greatest weakness? Strategy 1: Understand Your High Level Weakness: Content or Time Management Every student has different flaws in SAT Math. Some people aren't comfortable with the underlying math material. Others know the math material well, but can't solve questions quickly enough in the harsh time limit. Here's how you can figure out which one applies more to you: Take only the math sections of one practice test. We have the complete list of free practice tests here. For each section, use a timer and have it count down the time allotted for that section. Treat it like a real test. If time runs out for that section and you're 100% ready to move on, then move on. If you're not ready to move on, keep on working for as long as you need. For every new answer or answer that you change, mark it with a special note as "Extra Time." When you're ready, move on to the next section, and repeat the above until you finish the second math section. Grade your test using the answer key and score chart, but we want two scores: 1) The Realistic score you got under normal timing conditions, 2) The Extra Time score. This is why you marked the questions you answered or changed during Extra Time. Get what we're doing here? By marking which questions you did under Extra Time, we can figure out what score you got if you were given all the time you needed. This will help us figure out where your weaknesses lie. If you didn't take any extra time, then your Extra Time score is the same as your Realistic score. Here's a flowchart to help you figure this out: Was your Extra Time score a 700 or above? If NO (Extra Time score 700), then you have remaining content weaknesses. You might have weaknesses across a range of subjects, or a deep weakness in only a few subjects. (We'll cover this later). Your first plan of attack should be to develop more comfort with all SAT Math subjects. If YES (Extra Time score 700), then: Was your Realistic score a 700 or above? If NO (Extra Time score 700, Realistic 700), then that means you have a difference between your Extra Time score and your Realistic score. If this difference is more than 50 points, then you have some big problems with time management. We need to figure out why this is. Are you generally slow at math across most questions? Or did particular problems slow you down? Generally, doing a lot of practice questions and learning the most efficient solutions will help reduce your time. More on this later. If YES (both Extra Time and Realistic scores 700), then you have a really good shot at getting an 800. Compare your Extra Time and Realistic score- if they differed by more than 30 points, then you would benefit from learning how to solve questions more quickly. If not, then you likely can benefit from shoring up on your last content weaknesses and avoiding careless mistakes (more on this strategy later). Hopefully that makes sense. Typically I see that students have both timing and content issues, but you might find that one is much more dominant for you than the other. For example, if you can get an 800 with extra time, but score a 700 in regular time, you know exactly that you need to work on time management to get an 800. Strategy 2:Do a TON of Practice, and Understand Every Single Mistake On the path to perfection, you need to make sure every single one of your weak points is covered. Even one mistake on all of SAT Math will knock you down from an 800. The first step is simply to do a ton of practice. If you're studying from free materials or from books, you have access to a lot of practice questions in bulk. As part of our PrepScholar program, we have over 1,500 SAT questions customized to each skill. The second step- and the more important part- is to be ruthless about understanding your mistakes. Every mistake you make on a test happens for a reason.If you don't understand exactly why you missed that question, you will make that mistake over and over again. I've seen students who did 20 practice tests. They've solved over 3,000 questions, but they're still nowhere near an 800 on SAT Math. Why? They never understood their mistakes. They just hit their heads against the wall over and over again. Think of yourself as an exterminator, and your mistakes are cockroaches. You need to eliminate every single one- and find the source of each one- or else the restaurant you work for will be shut down. Here'swhat you need to do: on every practice test or question set that you take, mark every question that you're even 20% unsure about when you grade your test or quiz, review EVERY single question that you marked, and every incorrect question. This way even if you guessed a question correctly, you'll make sure to review it. in a notebook, write down 1) the gist of the question, 2) why you missed it, and 3) what you'll do to avoid that mistake in the future. Have separate sections by subject and sub-topic (algebra- solving equations, data analysis- experimental interpretation, etc.) It's not enough to just think about it and move on. It's not enough to just read the answer explanation. You have to think hard about why you specifically failed on this question. By taking this structured approach to your mistakes,you'll now have a running log of every question you missed, and your reflection on why. No excuses when it comes to your mistakes. Always Go Deeper- WHY Did You Miss a Math Question? Now, what are some common reasons that you missed a question? Don't just say, "I didn't get this question right." That's a cop out. Always take it one step further- what specifically did you miss, and what do you have to improve in the future? Here are some examples of common reasons you miss a question, and how you take the analysis one step further: Content:I didn't learn the math skill or knowledge needed to answer this question. One step further:What specific math skill do I need to learn, and how will I learn this skill? Incorrect Approach:I knew the content, but I didn't know how to approach this question. One step further:How do I solve the question? How will I solve questions like this in the future? Careless Error:I misread what the question was asking for or solved for the wrong thing. One step further:Why did I misread the question? What should I do in the future to avoid this? Get the idea? You're really digging into understanding why you're missing questions. Yes, this is hard, and it's draining, and it takes work. That's why most students who study ineffectively don't improve. But you're different. Just by reading this guide, you're already proving that you care more than other students. And if you apply these principles and analyze your mistakes, you'll improve more than other students too. Bonus: If all of this is making sense to you, you'd love our SAT prep program, PrepScholar. We designed our program around the concepts in this article, because they actually work.When you start with PrepScholar, you’ll take a diagnostic that will determine your weaknesses in over forty SAT skills.

There’s no other prep system out there that does it this way, which is why we get better score results than any other program on the market. Check it out today with a 5-day free trial: Strategy 3:If You Have Math Content Gaps, Be Ruthless About Filling Them Within SAT Math, you have to master a lot of subjects. At the high level, you need to know basic algebra, advanced algebra, data analysis, and geometry. Even further, within algebra, you need to know how to solve equations, how to deal with word problems, properties of functions, etc. Here's our complete mapping of all 24 skills you need in SAT Math: Basic Algebra Linear functions Single variable equations Systems of linear equations Absolute value Advanced Algebra Manipulating polynomials Quadratic equations Dividing polynomials Exponential functions Function notation Solving exponential equations Systems of equations with nonlinear equations Problem Solving and Data Analysis Ratios and proportions Scatterplots and graphs Categorical data and probabilities Experimental interpretation Mean, median, mode, standard deviation Additional Topics Coordinate geometry- lines and slopes Coordinate geometry- nonlinear functions Geometry- circles Geometry- lines and angles Geometry- solid geometry Geometry- triangles and polygons Trigonometry Complex numbers Whew! That's a handful. This might be a greater breakdown of skills then you're used to, but at PrepScholar we believe in grouping questions by specific skill so you can train most effectively. In our program, we break down all our SAT Math content into these detailed skills so you can train your specific weaknesses in focused groups. Unless you're a math whiz and are already scoring a 750-800, it's unlikely that you've mastered all of these evenly. You probably have different strengths and weaknesses across these subjects. If from the analysis of mistakes above you find that you have a content problem, you need to improve your understanding of that content. By Content problem, I mean that you're not comfortable with the underlying math concepts in a subject. Maybe you forgot how to solve a type of problem, or you forgot a formula to use, or you just don't remember the subject material. If you've identified one of these issues, you've spotted an opportunity for yourself to improve your score. Fill in the potholes of your understanding. Think of a mistake like discovering a cavity in your mouth. When your dentist fills in a cavity, he doesn't just patch up the hole right away. He cleans out the entire cavity, sterilizes it, then adds a filling. Content mistakes are similar- you have a weakness in a subject, say x-y coordinate geometry. This probably means you have a lot of other weaknesses in that subject other than the one identified by that question. Don't just focus on understanding that one question you missed. Take the opportunity to research that subject and get more practice in it. You need to find a way to get lesson material to teach yourself the main concepts that you're forgetting. Then you need to find more practice questions for this skill so you can drill your mistakes. In our SAT prep program PrepScholar, we do that work for you by splitting up our 1,500+ practice questions by skill and difficulty. If you're weak in algebra- solving equations, you get 20+ questions in a quiz dealing specifically with that skill. This repetitive practice fills up your content gap far better than any other method I know. Strategy 4: If You Miss a Question, Try It Again Before Reading the Explanation When you're doing practice questions, the first thing you probably do is read the answer explanation and at most reflect on it a little. This is a little too easy. I consider thispassive learning- you're not actively engaging with the mistake you made. Instead, try something different- find the correct answer choice (A-D), but don't look at the explanation. Instead, try to re-solve the question once over again and try to get the correct answer. This will often be hard. You couldn't solve it the first time, so why could you solve it the second time around? But this time, with less time pressure, you might spot a new strategy, or something else will pop up. Something will just "click" for you. When this happens, what you learned will stick with you for 20 times longer than if you just read an answer explanation. I know this from personal experience. Because you've struggled with it and reached a breakthrough, you retain that information far better than if you just passively absorbed the information. It's too easy to just read an answer explanation and have it go in one ear and out the other. You won't actually learn from your mistake, and you'll make that mistake over and over again. Treat each wrong question like a puzzle. Struggle with each wrong answer for up to 10 minutes. Only then if you don't get it should you read the answer explanation. Strategy 5: Master Every SAT Math Skill- Even the Rare Ones The SAT has an uneven balance of questions by skill. Algebra dominates the test, taking up over 50% of the test. This is somewhat good news, in that if you're an Algebra whiz, you'll do well on the bulk of SAT math. The bad news is that there's a long tail of straggling skills that show up just a few times a test. We've done a careful analysis of every math question on every official SAT test, and here are the LEAST common skills in SAT math. I'll show you the frequency of appearance, as well as the expected # of questions per test for that skill. Skill Frequency Expected Questions Per Test Dividing polynomials 1.72% 1 Trigonometry, radians 1.72% 1 Absolute value 1.29% 0.75 Complex numbers 1.29% 0.75 Experimental interpretation 0.86% 0.5 Lines and angles 0.86% 0.5 Solid geometry 0.86% 0.5 Systems of equations with nonlinear equations 0.86% 0.5 Function notation 0.43% 0.25 This might surprise you. Some of these skills have an expected # of questions lower than one. That's right: sometimes you might not even get a complex number or solid geometry question. But you have to know it anyway. You have to know it all. In some ways, this is really extreme. You have to know a LOT of topics in trigonometry, just to answer that one question per test. Here's an example: You need knowledge of radians and standard triangles to answer this question.To solve the question, you can realize that if the x length is√3, and the height is 1, then you know that this is a 30-60-90 triangle lying on its long side. Thus the angle is 30 degrees. Then, becauseÏ€ radians is 180 degrees, then the angle isÏ€/6 radians, so a = 6. But notice that you weren't tested on any other items in standard trigonometry- SOH CAH TOA, graphing functions like cos (90 + 2x), and converting between sin and cos. Yet you still need to know this, because you can't predict what they're going to test. This is also true of complex numbers, solid geometry (volumes, surface areas), absolute value, dividing polynomials, etc. This is the challenge of the 800 Math scorer- you need a wide BREADTH of knowledge as well as DEPTH of mastery in each one.No single test is going to test the entire breadth of your knowledge, but you must be prepared anyway. The way we handle this at PrepScholar, which is based on how I mastered the SAT myself, is to give you detailed lessons and quizzes for all 24 Math skills, and all Reading/Writing skills. For even the least common skills like complex numbers and solid geometry, you'll get dozens of questions to practice with and master the skill. You'll leave no stone unturned, which is why top scoring students love us. If you don't use PrepScholar, then you need to find great sources of practice content yourself, and to structure your study time optimally so you get both breadth and depth. Strategy 6: Finish With Extra Time and Double Check Your goal at the end of all this work is to get so good at SAT Math that you solve every question and have extra time left over at the end of the section to recheck your work. In high school and even now, I can finish SAT Math sections in about 60% of the time allotted. This means I finish a 25 minute section in 15 minutes or less, and a 55 minute section in 35 minutes. This gives me a TON of time to recheck my answers two times over and make sure I make no careless mistakes. How can I finish a section this quickly? It comes down to mastery of the math skills and a LOT of experience with the test. When I see a question, I usually know exactly what the College Board is asking for, and I've seen so many such questions that I know exactly how to solve it in the fewest steps needed. It comes from hard work and perseverance.If you're pretty far from this time benchmark, don't fret- it took me a lot of training and experience to get to this level. (After all, I've seen thousands of questions in my own SAT prep and when designing our PrepScholar SAT program). So let's say you finish a section ahead of time. What do you do with all that extra time? Don't rest and don't put your head down. Use this valuable time to double-check, even triple-check your work. Remember, even ONE question missed will bring you down from an 800- you need to achieve perfection. What's the best way to double-check your work? I have a reliable method that I follow: Re-read the question again. Question your assumption about what the question is about. If the question asks for a specific variable, make sure you're solving for that variable! Try to resolve the question another way. If I solved a question algebraically, I can recheck it by plugging in the solution. If I'm 100% sure I'm right on a question, I draw a huge check mark in the test book and never look at the question again. Even if I feel just a little twinge of remaining doubt, I'll come back to it on the third pass. At least 2 minutes before time's up, I rapidly double-check that I bubbled the answers correctly. I try to do this all at once so as not to waste time looking back and forth between the test book and the answer sheet. Go 5 at a time ("A D E C B") for more speed. Here's an example of solving a question two ways: First way: My natural instinct is to solve this algebraically. I know I can plug in numbers, but I feel that's slower and more error prone than getting a definitive answer through solving the equation. 3x - 5≠¥ 4x - 3 I can rearrange in my head in one step like so: -2≠¥ x (if you make careless mistakes, like the College Board expects you to do, it's worthwhile splitting it up into smaller steps) OK, so the solutioin set is numbers less than or equal to -2. This leaves answer A as NOT the solution. Doublecheck way:Now that I know answer A should be correct, I'm going to verify by plugging that value back in and expecting the inequality to fail: 3x - 5 ≠¥ 4x - 3 -3 - 5≠¥ -4 -3 -8≠¥ -7 That's obviously false, so I can verify that A is the right answer. At this point I'm confident enough that I can move on and not check this question again. Another time management tip: If you notice yourself spending more than 30 seconds on a problem and aren't clear how you'll get to the answer, skip and go to the next question. Even though you need a perfect raw score for an 800, don't be afraid to skip. You can come back to it later, and on your first pass it's more important to get as many points as possible. Quick Tip: Bubbling Answers Here's a bubbling tip that will save you 2 minutes per section. When I first started test taking in high school, I did what many students do: after I finished one question, I went to the bubble sheet and filled it in. Then I solved the next question. Finish question 1, bubble in answer 1. Finish question 2, bubble in answer 2. And so forth. This actually wastes a lot of time. You're distracting yourself between two distinct tasks- solving questions and bubbling in answers. This costs you time in both mental switching costs and in physically moving your hand and eyes to different areas of the test. Here's a better method: solve all your questions first in the book, then bubble all of them in at once. This has several huge advantages: you focus on each task one at a time, rather than switching between two different tasks. You also eliminate careless entry errors, like if you skip question 7 and bubble in question 8's answer into question 7's slot. By saving just 10 seconds per question, you get back 200 seconds on a section that has 20 questions. This is huge. Note: If you use this strategy, you should already be finishing the section with ample extra time to spare. Otherwise, you might run out of time before you have the chance to bubble in the answer choices all at once. 5 minutes before the section ends, make sure you bubble in the answers you already have. Strategy 7: Eliminate Careless Mistakes Careless mistakes are one of the most frustrating types of errors to make, and nearly everyone makes them, especially on Math. You know the underlying material, you know how to solve the question, and you're feeling good. But then you grade the quiz, and you find a careless mistake. Oops- the question asked for the perimeter of the circle and not the area, which is what you calculated. These types of errors are the most costly and frustrating. You've already put in a ton of work to master the underlying material, and here a question has tricked you into losing a point. This is why finishing the test early, like I mention above, is so helpful. You get extra time to take a breather and double-check your answers. If you find that careless mistakes are a recurring problem for you, here are some strategies to get rid of them: In the question, underline what the question is specifically asking you to solve for. It's so easy for the SAT to trick you into solving the wrong thing. If you're solving for a particular value (like length, area, etc), write the units down in the scratch space. Be careful with calculator entry. A missing parentheses makes a big difference. "4 + 9 / 2" is completely different from "(4 + 9) / 2" Avoid bubbling errors by using the Quick Tip above. Here's an example: This question is asking us to solve for y + z. Not x, y, or any other combination of variables. To make sure I remember this, I underline y + z, and I also write "y + z = ?" in the work space so that I remember what I'm solving for. You can bet that in many answer choices, the SAT will have trap answers for other things you can solve for, like x. (This one happens not to, but it's very common). Memorize the SAT Math Formulas. Strategy 8: Memorize the Formulas and Common Math Facts If you're still flipping to the front of the section to look at the math formulas, you haven't gotten to understand SAT Math well enough yet. Not only does this cost you time, it also indicates that you haven't practiced enough with SAT Math to have the required formulas come to you fluidly. Memorize the formulas at the front of the section and these common math facts: calculating slope from two points (rise over run) remainder when dividing a polynomial common right triangles: by angles 45-45-90 (1-1-√2) 30-60-90 (1-2-√3) by sides 3-4-5 5-12-13 formula forvolumes, surface areas We have a complete list of SAT Math formulas here. Strategy 9: Don't Overly Depend on the Calculator As you likely already know, Section 3 is a Math section forbidding the use of calculator, with 20 questions. Section 4 is a Math section that allows calculator, with 38 questions. The calculator is really useful for certain questions that require complex calculations, like multiplying decimals together or taking square roots of weird numbers. However, in many other situations, it's too much of a crutch, and it can make you soft. Learning to solve questions without the use of a calculator will strengthen your math intuition and force you to understand the underlying math, rather than relying on a calculator. Actually, every question on the SAT is solvable without a calculator. Because the College Board cares a lot about equality, it doesn't want to give an unfair advantage to students who have grown up with graphing calculators compared to students who can't afford them or never used them in school. So it designs questions that don't require advanced calculators to solve. Practically, this is important because some of the no-calculator questions are solvable WITH a calculator, and you need to wean yourself off of the calc. Here's an example: Yes- you can solve this by plugging it into your graphing calculator's systems of equations tool. But this appears on the no calculator section, so you have to get used to solving this with pen and paper. The second reason to depend less on the calculator is because solving without a calculator is actually faster in many cases. Here's an example: The calculator way to solve this would be to solve for the quadratic formula, 0 = -4.9 t2 + 25t. You can plug it in and the calculator will spit out two values for t. How I would naturally approach is to factor first: 0 = t (-4.9t + 25) Obviously t = 0 is one solution, but the other solution is pretty easy to find too.I don't even need to use the calculator- I know 4.9 is close to 5, so I can see that t is close to 5. This is answer D. For me, the second way is faster and feels more robust than the first. I know I've solved for t definitively, and I'm confident in my answer choice. Whereas if I used a calculator, I don't have a "feel" for the solution- I'm purely trusting the calculator and what I entered into the calculator as correct. Now, when I doublecheck (Strategy 6), I might solve it a different way by plugging in the answer choices. I'll try plugging in answer choices C and D, and it'll be clear that Dis the better answer. But this is reserved for answer checking, rather than the first time I solve it. Being able to solve SAT Math questions without a calculator will train your SAT Math skills more rigorously. This is important when you're aiming for a perfect math score. Strategy 10: Keep a Calm Mind During the Test, No Matter What Now you know what it takes to achieve perfection on SAT Math. You know that it's critical to get a perfect raw score, or you might score a 780. This makes a lot of students freak out during the test. "I can't solve this question...my 800 is gone...I'm getting more nervous and I have to skip the next question too..." You can see how quickly you can unravel like this. Before you know it, you're scoring way worse than you ever did on a practice test. You need to learn to be mentally strong, like an athlete on game day. Yes, you might have to skip a question on the first pass through. Maybe even two in a row. But you've practiced hard up to this point. You know this stuff, and you'll come back to those questions and get it later. You need to keep up a positive mindset during the test, or you'll crumble. And in the worst case, maybe you won't get an 800. But if you've consistently been getting 800's on the practice tests, you likely won't go much lower than 750- and that's still really good. Recap: How to Get a Perfect SAT Math Score Those are the main strategies I have for you to improve your SAT math score to an 800. If you're scoring above a 600 right now, with hard work and smart studying, you can raise it to a perfect SAT Math score. Notice that I didn't actually teach you that much math content. I didn't point to any specific math solutions that will instantly raise your score. That's because these one-size-fits-all, guaranteed strategies don't really exist. (And anyone who tells you this is deceiving you). Every student is different. Instead, you need to understand where you're falling short, and drill those weaknesses continuously. You also need to be thoughtful about your mistakes and leave no mistake ignored. If you want to go back and review any strategies, here are quick links to them: Strategy 1: Understand Your High Level Weakness: Content or Time Management Strategy 2:Do a Ton of Practice, and Understand Every Single Mistake Strategy 3:If You Have Math Content Gaps, Be Ruthless About Filling Them Strategy 4:If You Miss a Question, Re-Solve It First Strategy 5: Master Every SAT Math Skill- Even the Rare Ones Strategy 6: Finish With Extra Time and Double Check Strategy 7: Eliminate Careless Mistakes Strategy 8: Memorize the Formulas and Common Math Facts Strategy 9: Don't Overly Depend on the Calculator Strategy 10: Keep a Calm Mind During the Test, No Matter What Keep reading for more resources on how to boost your SAT score.

Create Research Questions Essay Example | Topics and Well Written Essays - 750 words

Create Research Questions - Essay Example The research questions that will be looked at in this article will focus on the proposals that were produced by Padgett with more emphasis on what should be expected in future research studies in this field. One of the research proposals focused on a study of treatment related and substance related outcomes based on the 48 month study conducted on the housing first and treatment first program for the homeless people suffering from severe mental illness (Padget, 2006). The main aim of the study was to determine whether the findings of the previous studies can be sustained or they may end up changing after some period of time. In order to look at what should be expected in the future, the following research questions will be addressed: The research questions above reflect on some aspects that were discussed by Padget (2004) in her proposals based on the studies that were conducted. In order for a research methodology to be selected there is need to carefully check up on the research questions so as to ascertain the nature of the methodology to be used. In this case a qualitative methodology will be more appropriate based on the fact that empirical materials will be collected to in order to carry out the study. With regards to the case study on the homeless people suffering with severe mental illness the appropriate method of collecting data for the this study will be through sampling and recruitment. Participants will be chosen based on selected criteria after which interviews will be conducted on each respective participant in order to collect their findings. It is well noted that the approval of each participant greatly considered before pushing forward with the research study. A structured interview will be best suited in carrying out the research study and thus the research questions will be analysed in detail based on the response of

Shipping Logistics in the UK Essay Example | Topics and Well Written Essays - 1500 words

Shipping Logistics in the UK - Essay Example Data for the research will be gathered from both primary and secondary data where all participants will be selected randomly to reduce biasness in the research. Questionnaires will be used to help in data collection where telephone interviews will be used to help reduce cost of travelling. After data has been collected it will be analyzed using computer programs such as Ms. Excel and SPSS and presented using tables and graphs. Confidentiality will be observed as a strategy for enforcing ethics sin research. Background of the Research The term shipping has changed from what it was associated with in the past to include any form of transport moving goods from one point to another (Lun, Lai and Cheng, 2010, p. 12). Previously, the term the term was associated with water borne transport. Consequently this extended meaning makes the industry a complex and dynamic. Logistics is described as the management of the flow of commodities from the point of production to target point with an aim o f meeting the needs of customers and companies. Logistics calls for assimilation of information, inventory, transportation, warehousing, handling and packaging of materials and security of the goods. According to Fremont (2009, p. 1), for the last 50 years, containerization has turned into the prop of globalization. Additionally, this period has seen increased international trade and consequently this calls for efficient shipping logistics. Companies and businesses demand for better synchronized shipping activities in terms of location and space by development of logistics chains. The total value of the UK logistics industry was $105.7 billion in 2010 having grown by 9.9 percent in the 2009-10 fiscal years. This sector employs thousands of people and supports a significant proportion of the country’s economy. However, the sector is facing various constrains which may impede the efficient discharge of its responsibilities to different stakeholders. One primary concern in the s ector is the security threats caused by pirates and increased terrorism cases (Askins, 2012, p. 15). The other issue facing the UK shipping sector is that fact that with enlargement of European Union, competition has increased with the newer member states to the EU who have lower operational costs. Moreover, in the late 1990s, there was increased demand for bigger containers and tanker ships overstretched the capacity of the available ports thereby impeding trade. In light of these developments in this sector, it is critical to carry out a research into the shipping logistics in UK to understand the processes and procedures implemented by different companies to ensure smooth trade between UK and other countries. Aim and Objectives of the Research The aim of this research is to understand shipping logistics in United Kingdom; the process, procedures and policies that control shipping in UK. Moreover, the research will help understand any impediments to the shipping logistics in UK an d the problems faced by shippers in UK in relation to other shippers in the European Union. Objectives of the research 1. To find the security issues facing shippers in UK 2. To assess handling of goods at the port in UK 3. To investigate whether there is adequate capacity for shipping in UK Justification of the research Findings from this research will be help regulatory authorities make better informed decisions on

What Is Knowledge from the Meno Essay Example for Free

What Is Knowledge from the Meno Essay The opinions which we believe and are right, are called â€Å"true opinions†. According to Plato’s dialogue from The Meno, when true opinions remain stable they can serve equally as well as knowledge until people forget their opinion or change their mind some time later. Knowledge is â€Å"tied down† by giving the reasons why it is so. Opinions, even if beautiful, can â€Å"escape from a man’s mind† without justification. Moreover, opinions lead less reliability compare with knowledge (Gendler, Siegel Cahn, 2008, P344). Therefore, people should prefer knowledge to opinion since the former is more correct and lasts longer. Opinion functions as well as knowledge when the opinion is right or true. For instance, a person who does not know how to turn on the computer eventually turns it on by pressing buttons randomly. Thus, true opinion and knowledge work the same at this point. However, this true opinion may not be replicable or reliable over time. For this, the person would need the knowledge that computer start buttons contain a certain logo. Plato argues that knowledge is superior to true opinion. He says that true opinions are not willing to remain long, and they are not worth much, until one ties them down by giving an account of the reason why they are correct (Gendler, Siegel Cahn, 2008, P344). We can see that mere true opinion is not stable, and it can be fleeting. For example, we see the moon, and may first think that the moon shines by itself if we do not have any knowledge about this. The next day, if we do not see any moonlight, we may think that the moon does not shine by itself. Although the latter idea is correct, and could serve as well as knowledge for a time, our opinion can change unpredictably. On the other hand, if we have knowledge that the moon reflects sunlight, we understand that the moon does not shine by itself. Knowledge gives more consistency and predictablily than true opinion. Furthermore, opinions are weak because they can be influenced by feelings, and emotions can occur at any time, anywhere. For example, if I am in a good mood on a sunny day, I think my cat is cute when it is running around. If it rains the next day, the weather makes me annoyed, and I think my cat is naughty when it is running around. In this example, the opinion that my cat is naughty has no justification because the cat did not change its behavior to make it naughty. With justification and knowledge, people can develop civilization and improve their quality of life in areas such as space exploration, transportation, education and medicine. For example, without a foundation of reliable knowledge, we could not develop safe medicine or safe airplanes; the risk and expense of basing our lives on true opinion is too great, because it has not been justified. Plato has defined knowledge as having three components: truth, belief and justification. First, it must be accurate and we must believe it. For example, when we say this coffee is hot, it must be hot, and we must believe it is hot. Second, by justification, Plato means that we must have reasons explaining why it is correct and prove our idea. If not, it is an opinion rather than knowledge. However, if we can prove our opinion, it becomes knowledge. For instance, recent news said that an Italian experiment had unveiled proof that fundamental particles known as neutrinos can travel faster than light. As we know, in the past people thought the speed of light was the fastest. After the experiment had been conducted and evidenced the result, this new information led people to correct their old opinion because they had better justification. When we find out that our old idea is wrong and have a new idea with justification, the old idea no longer has justification. This is the reason why truth, belief and justification have to be involved in knowledge. In Plato’s view, true opinions function as knowledge only when people understand the reason behind the truth or have evidence of it. For example, if my sister holds a cup of coffee and walks into classroom, her classmates will probably think that the coffee belongs to her. This would be a true opinion if I had bought the coffee for her. On the other hand, people who had seen me buying the coffee for my sister would regard this information as knowledge. In sum, true opinion contains truth and belief, but it does not have justification. Plato illustrates this idea with the image of Daedalus’s statue. Daedalus is a skillful craftsman and artisan. His statues were so realistic that people thought it could run away. Therefore, Plato mentions the statue as a metaphor for true opinion which will be forgotten by people over time. â€Å"To acquire an untied work of Daedalus is not worth much, like acquiring a runaway slave, for it does not remain, but it is worth much if tied down, for his works are very beautiful (Gendler, Siegel Cahn, 2008). † The tied-down statue symbolizes knowledge, and the ropes are the reasons why, the justification. This metaphor perfectly shows the relationship between opinion and knowledge. Through reading Plato and his teacher Socrates’ dialogue, I understand the differences between opinion, true opinion and knowledge. I also found out why knowledge is more important than true opinion. Opinion will not be valid all the time. In contrast, knowledge is more stable because it contains justification, and therefore, is superior to true opinion. Plato’s basic definition of knowledge and its three parts provides a clear basis for further philosophical discussion, such as what is accepted as logical and solid justification.

Future of Signals Analysis :: essays research papers

FUTURE OF SIGNALS ANALYSIS   Ã‚  Ã‚  Ã‚  Ã‚  Protocols for transferring data, information, or any other signals communication have dramatically changed. Breakthrough technology has changed the way signals are transmitted, collected, analyzed and distributed. Technology has exceeded well beyond first generation robust computers to third and forth generation supercomputers that are small enough to fit in a person’s shirt pocket. Signals analysts are expected to engage and explore the realms of the unknown and conquer it with decisive and accurate analysis. The future holds an extremely challenging problem for signals analysis. The conglomerate of highly skilled analysts is extremely small which poses a problem because as the global market gets larger, skilled signal analysts have a difficult time keeping pace. The Internet has long surpassed its expectations and survivability by at least three folds since the time of its creation. The Internet has provided the ability to process large quantities of data from anywhere in the world with corresponding communication bandwidth with a few simple mouse clicks. The Internet appears to be a conduit for up to 95% of the world’s communication transmissions. A state of the art desktop computer with Internet access is universally available to millions of anonymous individuals at affordable rates. Ingenious individuals constantly cover their footprints while pinging specific websites and e-mail addresses to avoid detection from the United States Intelligence Community.   Ã‚  Ã‚  Ã‚  Ã‚  Cryptology applications are becoming extremely advanced and more difficult to distinguish. Scientists and mathematicians are spending years developing indestructible encrypted codes, while also trying to decipher codes. Data is sometimes transmitted in such an unpredictable manner that analysts have difficulty understanding the chaotic system. Cryptology has proved its effectiveness through two World Wars. Combining legacy with state of the art technology has the potential to create an awesome defense. Less than  ½% of people will send crucial data or information through unsecured communications. Knowing the severity of decoding encrypted messages, signal analysts must remain aware of new trends and occurring patterns to make successful calls about intelligence.   Ã‚  Ã‚  Ã‚  Ã‚  AT&T and MCI telecommunication companies have laid enough fiber optic cables to reach the sun and back to the earth at least three times. There are many more smaller private and commercial companies that have also laid cable throughout the world. The advantage of fiber optic cables is that they do not emit external signals while transmitting. There are over 200 fibers within the cable, which can transmit data or information.

Hunger Games Theme

What would we do if we were chosen at random to fight for our life? Would we just let it happen? Would we fight back and try our best to keep out dignity? Or would we do whatever it takes just to stay alive, even if it means losing site of who we really are? These are all decisions that Peeta and Katniss, two kids from a city called Panem had to make all by themselves. The novel The Hunger Games by Suzanne Collins has many themes, but the most important overall, is the importance of keeping dignity and humanity while fighting for our life. In the Hunger Games, a sixteen year old girl named Katniss and a sixteen year old boy named Peeta are chosen to go into the Hunger Games, where they will fight for their lives. During past years, competitors in the Hunger Games would do a number of unspeakable things in order to survive. Peeta however is the complete opposite. He wants to die with dignity. First off, in the novel The Hunger Games, by Suzanne Collins, many things go wrong in Panem, the society that the main characters Katniss and Peeta live in. For example, their society is filled with many things such as war, starvation, poverty, and violence. Peeta and Katnis have been taught since they were little that no matter what you are doing you have to keep your dignity while doing it. Even if it is fighting to the death. The way that both Peeta and Katniss have grown up comes in really handy during the Hunger Games. It makes it extremely easier for them to keep their dignity during the games. However, many competitors will do anything in order to survive, wouldn’t you? Peeta however, is very different; he believes that if he is going to die, he should at least go with his dignity. This means that while everyone else loses their minds, he will still think straight and won’t do anything outrageous in order to survive. For example, a girl from district 9 said â€Å"here’s some advice, just stay alive† (127). This quote shows that she believes the only thing that matters is staying alive. She will risk anything to live, even her humanity and dignity. Peeta however, would basically rather die with his dignity than live knowing he completely lost his dignity and humanity during the Hunger Games. To Peeta, his dignity is just as important as his own life. The competitors in the Hunger Games family and friends are also loosing spite of their humanity and dignity even though it may not seem like it to them. The family members show their loss of dignity when all of them just sit back and watch as their loved ones battle for their lives. It is just one big game to them. Celebrations are thrown if their loved one kills another person’s loved one. They don’t even comfort the other family at all. Everyone just parties while one family is having one of the worst possible days of their lives. Watching as somebody’s child is being killed isn’t right. Imagine if our society was like this. We wouldn’t just sit back and watch as our family and friends die before our eyes, would we? The novel The Hunger Games is similar to the novel Lord of the Flies by William Golding in a few ways. The most important however is the characters loss of humanity and dignity, which occurs in both novels. In Lord of the Flies, the large groups of boys that are stranded on the island lose sight of what is really important to them. They get caught up in trying to stay alive and doing whatever it takes to stay alive. Jack, from Lord of the Flies, ran around chanting â€Å"Kill the pig. Cut her throat. Spill her blood† (69). This quote shows us that the boys are starting to lose their dignity. This is exactly what happens in Suzanne Collins, Hunger Games. All of the competitors chosen to compete in the annual Hunger Games get caught up in killing people to stay alive that they forget who they really are inside. Ralph, the boy from the novel Lord of the Flies is very similar to Peeta, the boy from the novel Hunger Games in many ways. For example, both Ralph and Peeta are one of the only people to keep their humanity and dignity while they are stranded on an island or in this case fighting to the death in a huge arena. All of the boys in the novel Lord of the Flies lose their dignity and humanity except for Ralph and piggy who stay sane. This is very similar to the Hunger Games. Everyone in districts one through eleven go crazy and forget who they are except for two people. Only Peeta and katniss who are from District 12 keep their dignity while struggling to stay alive. Peeta says â€Å"at least let me die with my dignity† (167). This quote shows us that Peeta won’t lose his humanity and dignity no matter what. In conclusion, the novel The Hunger Games by Suzanne Collins shows us how society could end up if we lose sight of our dignity. She shows us that just because something bad could happen doesn’t mean that we have to forget what really matters to us, or even forget who we truly are behind all of the violent, or just plain old fake acts that we would have to put on just to live through the Hunger Games. She shows us through the eyes of Peeta that even when something gets tough, we just have to work through it and keep our head held high.

How Is Racism Presented in the Novel of Roll of Thunder, Hear My Cry?

How is racism presented in the novel of Roll of Thunder, Hear My Cry? Roll of Thunder, Hear My Cry is a novel based in the Southern States of America in the 1930’s and deals with the theme of Racism amongst other themes. Racism is being prejudice or discriminating against someone of a different race based on such a belief. Following on from the Civil War, America experienced ‘The Great Depression’ and it affected everyone, especially blacks.Mildred Taylor reveals examples of racism and racist behaviour throughout the novel based on her own experiences. In this essay, I will discuss what blacks were subjected to and how racism is presented in this novel. Right from the very start, the Logan Children, although they have been protected from racism, experience unjust acts against them. The books that the Logan Children use in school were previously owned by the white children until they were considered too tatty for them to use.The books also include the race of the s tudent, using the word â€Å"nigra. † However, Little Man and Cassie do not know how to react to this: â€Å"†¦he sucked in his breath and sprang from his chair like a wounded animal, flinging the book onto the floor and stomping madly upon it. † This demonstrates how naive Little Man is as he reacts angry and offended because he has not been treated in that way before. This also shows that blacks do not need or require books that are in good condition because of the racist opinions of the whites.TJ Avery, a character introduced early on in the novel, is accustomed to racism and recognises it. He frequently gossips and enlightens the Logan Children about racist acts. An example of this is when he passes on details concerning the Berry Burnings: â€Å"I betcha I could give y’all an earful ‘bout that burnin’ last night† The Logan Children act surprised and reply with ‘Burning? What burning? ’ which further reveals their innoce nce and naivety to racism. Moreover, this illustrates TJ’s understanding of unjust and prejudice acts against black people.At the end of the novel, these prejudice and unjust acts are witnessed by the Logan Children when TJ’s family are brutally attacked by the ‘Night Men’. TJ is blamed for the murder of Mr. Barnett, a white man, when the offence was committed by R. W and Melvin Simms (two white boys). However, TJ was only an accomplice in the break in of Mr. Barnett’s store but this does not prevent the ‘Night Men’ attacking TJ and his family. They do this because it gives them reason to physically and violently assault the Avery family just because they’re black: â€Å"†¦dragged from the ouse on his knees. His face was bloody and when he tried to speak he cried with pain. † This shows they are treated like animals and not as equals. TJ is considered disposable by the white men as they do not care what happens to him . Also the fact that there was no legal intervention displays how racist the community really was towards black people. In my opinion, I think Mildred Taylor included this in the novel to show that no one stood up to it even though it was unjust and unfair. In contrast to this, not every white character in the book is racist.For example, Jeremy Simms and Mr. Jamison. Jeremy Simms, a white boy, wants to befriend the Logan Children despite knowing he will be punished for his actions as it is considered unacceptable for a white boy to socially interact with black children: â€Å"Jeremy grew even more pale, ‘C-cause I just likes y’all’ he stammered† This shows what a brave and courageous character he is to look beyond the colour of a person’s skin for the sake friendship. Mildred Taylor, I believe, included this in the book to show that not everyone was racist and as it gives the reader a sense of hope.In conclusion, this is a very thought provoking nov el as it presents racism in an effective way. This is due to Mildred Taylor writing it based on her own experiences which makes it very realistic. Furthermore, as the book was written from a child’s perspective, it makes it easy to relate to and easier to understand. Racism was obvious from an early age as black children were made to feel unworthy even though some were protected from it by their parents. Also that for some their day to day reality of living with racism forced them to mature and grow up.Although unjust and unfair, racism was allowed to fester as there was no movement within the white community to prevent it continuing; most white people and black people just accepted it as they felt there was nothing they could do or it was too dangerous to stand up to. However, the novel shows there was a glimmer of hope as there were white people who disagreed with racism and were prepared to look beyond the colour of black people’s skin. I feel this book is suggestin g that racism affected black people’s, of all ages, day to day lives and were treated with prejudice and discrimination but with violent consequences. David Constant 9F

Nature Tourism Essay Example | Topics and Well Written Essays - 2750 words

Nature Tourism - Essay Example Motivation relates to the choice of destination and activities, which are expected to relate to trip satisfaction and subsequent travel related intentions. The theories of motivation are a way of understanding the tourist expectations formation, that is, the tourist behaviour. Do they accurately assess and analyse tourist behaviour If so, to what extent Some of the functions of attitude are knowledge, ego, defence, value expression, utility and social adaptation; these functions act as mediators between drives or motives and values or situations. The theory of tourism motivation explains the behaviour pattern and assists in the satisfaction of it's underlying cognitive and emotional motives. The two systems of emotions and cognition differ in the degree of control a person has over their generation and manipulation. The term cognition refers to the mental representations such as knowledge or beliefs. Emotions encompass drives, feelings and instincts. The two jointly contribute to tourism motivation process. Motive is a distinct type of learned or conceived action in the form of behaviour. Motivation contains results of a situation-person interaction. One and the same motive can generate situational different behaviour; while different motives can generate very similar behaviour. A person experiences a press or a pull, which usually appears in the guise of a threat of harm or promise of benefit. Both need and press, combine to form an equivalent group of behavioural situations. (Heckhausen, 1989.) When motives transform to motivation, the process of choosing specific destination and activities begin. "Motivation is based on feelings of competence and self determination." (Deci and Ryan, 1985.) Tourist motivation is a set of needs, which predispose a person to participate in a tourist activity. The important antecedents of individual motivation are cultural background, values, market communication, experience, and consumer self-perception. 3. Motivation of Nature Tourism People who live in cities are motivated to travel as tourists to areas of wilderness because they need to escape from an artificial monotonous environment. Gray's Travel Motivation Theory gives us two motives; first is the desire to go from a known place to an unknown place and the second is to go to a place which can provide the traveler with special facilities, that do not exist in the place of residence. This theory does not completely cover the aspects of nature tourism. It will be worthwhile to have a look at the Career Ladder Theory, which emphasizes that people have a range of motives for seeking out holiday experiences. With different levels, it allows for many motives. It is dynamic and covers the seven requirements, which are considered to be good to assess the theory of tourist motivation. These seven requirements are, it functions as a true theory; it appeals to different users; it is easy to

FINANCIAL ACCOUNTING Essay Example | Topics and Well Written Essays - 1250 words

FINANCIAL ACCOUNTING - Essay Example More specifically, the report will answer the question, â€Å"What was the adjusted profit for the financial year ending 30th September 2010 and which were the actual adjustments made to the accounts to reach at that amount?† 1. In this case the problem lies in the fact that the financial assistant was not aware of the new changes where there was a review in 31st March 2010 giving the plant a useful life of 5 years. The depreciation rate that should be reflected in the financial statements and in the comptation of profits for the financial year should be based on the reviewed value. This is when IAS number 16 has been applied. The adjustments are going to be shown in the appendix number (1). A journal entry is to be used to correct this error by the Financial Assistant. 2. This was a case by the Assistant where he did not consider the review of the value of the building in 1st October 2009. This is from the original  £700,000 to  £1,200,000. The review was to affect the profits by being included as a profit or gain to the firm rather than opening a revaluation account and reflecting the same in the asset account (in this case the building). IAS 16 is also applicable in this case as it is the most appropriate. Adjustments necessary are shown in Appendix (2). 3. This is a case where the Investment property was shown under land and buildings. There was no clear cut line as to where it should have been included. Though, IAS 16 still applies in this case no action is going to be made in making a journal entry to rectify. This is since there are neither rates nor the depreciation rate applicable. Investment property shown in 30.09.2009:  £800,000 Adjustment: since the rate of depreciation is not given nor the useful years as well as how the assistant treated it during the current financial year, no adjustment is to be

Knolege creatain - Essay Example niversities are responsible for this in efficient growth of clusters and business industries are putting in no effort to make use of them for growth and innovation. Each sector has to play a certain role with constant coordination to overcome crises. Grant (1996) suggests that knowledge infuses increased performance opportunities for firms able to understand, and utilize relevant knowledge efficiently. The role of a business industry is to sponsor extensive funds for research work to universities who are struggling hard to raise funds beside their limited funds from government to bring in exceptional innovations, technology and knowledge. Mode 2 is interconnected and not possible without a thorough work of mode 1, therefore business industry should collaborate with universities to carry on research and expand the area of innovative knowledge with practical experiments over it and simultaneously, business industry should give internships, job training and design an individual area to comprehend mode 1 studies into mode 2 work which can examine the loopholes in academic knowledge and its implementation in practical experiences which is not possib le in isolated environment of universities. This changing wave of knowledge economy has a great impact and acts as a driving force towards new opportunities for industries and will smooth the dynamics between universities and industries in the long run. Students independently cannot achieve a complete combination of theoretical and practical work if exposure is not provided but can help demonstrate through their university projects, though not sufficient to unfold their growing minds but can contribute. It is beneficial for students to use their academia through internships or part time jobs in the relevant industry in summers or annual vacations. Universities are the pathways for students but students themselves should take initiative to promote practical enforcement of their academic theories however on large scale,

Endocrine System Communication

Endocrine System Communication Explain the importance of intercellular communication and describe the mechanism involved. Intercellular communication is important because it assist the nervous system to elongate the long-term process of growth, development, or reproduction. The endocrine system uses chemical messengers to relay information and instructions between cells. One of the mechanisms involved in intercellular communication is know as direct communication this communication is rare but is important when it occurs. This is when two cells of the same type and the cells must be in extensive physical contact. The cells are so close they function as one. The majority of the communication is known as paracrine communication which is where the cell continuously exchanges chemical messages between each other so they are in sink with one another. Compare and contrast the modes of intercellular communication used by the endocrine and nervous systems and discuss the functional significance of the differences between the two systems. The nervous system performs short term â€Å"crisis management† and the endocrine system regulates long-term, ongoing metabolic processes. The endocrine system uses endocrine communication which helps regulate hormones through the circulatory system and the nervous system dose not have the capability to do this. Another significant difference is synaptic communication, the nervous system uses this form of communication of neurons to release neurotransmitter at a synapse very close to a target cell that bears the right receptors. This form of communication allows the body to react quickly to situations to escape from harm. Explain the general mechanisms of hormonal action and identify which hormone types work through each mechanisms. A hormone receptor is a protein molecule to which a particular molecule binds strongly. Each cell has receptors for responding to several different hormones, but cells in different tissues have different combinations of receptors. For every cell, the presence or absence of a specific receptor determines the cells hormonal sensitivities. Hormone receptors are located either on the cell membrane or inside the cell. The mechanisms of hormonal action are that receptors for catecholamines, peptide hormones and eicosanoids are in the cell membrane of target cells. Thyroid and steroid hormones cross the cell membrane and bind to receptors in the cytoplasm or nucleus, activating or inactivating specific genes. Describe the control of endocrine organs. The endocrine organs are controlled by three mechanisms of the hypothalamic control. One is the secretion of regulatory hormones to control activity of anterior lobe of pituitary gland. Two the production of ADH and oxytocin. And finally is the control of sympathetic output to adrenal medullae. Explain the structural and functional relationship between the pituitary gland and the hypothalamus. The pituitary gland releases nine important peptide hormones that all bind to the membrane receptors and use cyclic-AMP as a second messenger. The pituitary gland hangs inferior to the hypothalamus which all the anterior lobe of the pituitary gland to help in the function of the hypophyseal portal system. By the hypothalamus secreting specific regulatory hormones it controls the production of hormones in the anterior lobe. This whole system works to secret hormones from the hypothalamus through the pituitary gland in a network of capillaries that are connected. All this ensures that all the hypothalamic hormones entering the portal vessels will reach the target cells in the anterior lobe of the pituitary gland before entering general circulation. Predict how alternations in hormone production, delivery, or reception by target tissues would affect its action and blood concentration levels. Describe the factors that could determine a cells hormonal sensitivity. Cells sensitivity is determined by two factors down-regulation and up-regulation. Down regulation is a process in which the presence of a hormone triggers a decrease in the number of hormone receptors. This process is when levels of particular hormones are high, cells become less sensitive to it. Up-regulation is a process in which the absence of a hormone triggers an increase in the number of hormone receptors. In this process the levels of a particular hormone are low, cells become more sensitive to it. Identify the hormones produced by the anterior and posterior lobes of the pituitary gland and specify the functions of those hormones. The anterior lobe produces seven hormones: Thyroid-stimulating hormone (TSH) targets the thyroid gland and triggers the release of thyroid hormones. As circulation concentrations of thyroid hormones rise, the rate of TRH and TSH production decline. Adrenocorticotropic hormone (ACTH) stimulates the release of steroid hormones by the adrenal cortex and targets cells that produce glucocorticoids. Gonadotropins regulate the activities of the gonads. Follicle-stimulating hormone (FSH) promotes follicle development in females and, in combination with luteinizing hormone, stimulates the secretion if estrogen by ovarian cells. In males, FSH stimulates sustentacular cells, specialized cells in the tubules where sperm differentiate. Luteinizing hormone (LH) induces ovulation, the production of reproductive cell in females. Also promotes the secretion, by the ovaries, of estrogen and the progestin, which prepare the body for pregnancy. In male hormone is sometimes called interstitial cell- stimulating hormone (ICSH), because it stimulates the production of sex hormones by the interstitial cells of the testes. Prolactin (PRL) works with other hormones to stimulate mammary gland development. Growth hormone (GH) stimulates cell growth and replication by accelerating the rate of protein synthesis. The posterior lobe produces two hormones: Antidiuretic hormone (ADH) is released in response to a variety of stimuli, most notably a rise in the solute concentration in the blood or a fall in blood volume or blood pressure. A rise in the solute concentration stimulates specialized hypothalamic neurons. Oxytocin (OT) stimulates smooth muscles contraction in the wall of the uterus, promoting labor and delivery. After delivery this hormones stimulates the contraction of myoepithelial cells around the secretory alveoli and the ducts of the mammary gland, promoting the ejection of milk. Discussion the results of abnormal levels of pituitary hormones Abnormal levels of pituitary hormones can have a cast and complex impact on the growth, fertility, and function on the human body via the effect of the hormones on their target organs. Diseases anywhere from asthma to growth problems can occur. Identify the hormones produced by the thyroid gland, specify the functions of those hormones, and discuss the causes and results of abnormal levels of thyroid hormones. The thyroid gland produces thyroglobulin, tyrosine, and thyroxine. The functions of these hormones are: Thyroid hormones enter target cells by means of an energy dependent transport system and they affect almost every cell in the body. Thyroid hormones bound to cytoplasmic receptors are held in storage until intracellular levels of thyroid hormone decline. Thyroid hormones bound to mitochondria increase ATP production. Thyroid hormones bound to receptors in the nucleus activates genes that control energy utilization. The calorigenic effect: the cell consumes more energy resulting in increased heat generation. In growing children, thyroid hormones are essential to normal development of the skeletal, muscular, and nervous systems. The thyroid gland is primarily responsible for a strong, immediate, and short-lived increase in the rate of cellular metabolism. The major factor controlling the rate of thyroid hormone release is the concentration of TSH in the circulating blood. The causes of abnormal levels of thyroid hormones can create an iodide deficiency because in the U.S. we consume more than they daily amount needed. Thyroid hormone production declines, regardless of the circulating levels of TSH. Describe the functions of the parathyroid hormones, and the effects of abnormal functions of each hormone. Parathyroid hormone has four major effects: 1. It stimulates osteoclasts, accelerating mineral turnover and the release of Ca2+ from bone. 2. It inhibits osteoblasts, reducing the rate of calcium deposition in bone. 3. It enhances the reabsorption of Ca2+ at the kidneys, reducing urinary losses. 4. It stimulates the formation and secretion of calcitriol at the kidneys. The effects of calcitriol complement or enhance those of PTH, but one major effect of calcitriol is the enhancement of Ca2+ and PO43- absorption by the digestive tract. The parathyroid glands, aided by calcitriol, are the primary regulators of blood calcium I levels in healthy adults. When the parathyroid calcium levels become abnormal there are two disorders that can occur. Hypoparathyroidism the gland secretes low calcium concentrations in body fluid. Hyperparathyroidism is when calcium concentrations become abnormally high. Identify the hormones produced by the adrenal cortex and medulla and specify the functions of each hormone The adrenal cortex secrets the hormones adrenocortical, mineralocorticoids, glucocorticoids and androgens. The adrenocortical steroids or corticosteroids are vital: if the adrenal glands are destroyed or removed, the individual will die unless corticosteroids are administered. Mineralocorticoids increase renal reabsorption of Na+ and water which accelerates urinary loss of potassium. Glucocorticoids release amino acids from skeletal muscles and lipids from adipose tissue; promote liver formation of glucose and glycogen; promotes peripheral utilization of lipids; anti-inflammatory effects. Androgens are not important in men; encourages bone growth, muscle growth, and blood formation in children and women. The adrenal medulla secrets epinephrine and norepinephrine. These hormones increase cardiac activity, blood pressure, glycogen breakdown, blood glucose levels; releases lipids by adipose tissue. Also this is where the fight or flight syndrome is sparked. Discuss the results of abnormal levels of adrenal hormone production When the adrenal hormone becomes abnormal it produces several different disorders. The first is hypoaldosteronism; the zona glomerulosa fails to produce enough aldosterone, generally either as an early sign of adrenal insufficiency or because the kidneys are not releasing adequate amounts of rein. A rare but serious disorder can occur called Addisons disease which results from inadequate stimulations of the zona fasciculata by the pituitary hormone ACTH or, more commonly, from the inability of the adrenal cells to synthesize the necessary hormones, generally from adrenal cell loss caused by autoimmune problems. Another disease is Cushings disease which results from overproduction of glucocorticoids. There is another aspect of abnormal production of adrenal hormones that affects men and womens sexual characteristics called adrenogenital syndrome. In women, this condition leads to the gradual development of male secondary sex characteristics, including body and facial hair patters. In male to causes an increase of estrogen resulting in larger breast tissue or other female secondary sex characteristics. Last but not least there is a disorder of the adrenal medulla called pheochromocytoma which is an overproduction of epinephrine that causes a tumor that produces catecholamines in massive quantities. Describe the functions of the hormones produced by the pineal gland. It contains pinealocytes, which synthesize the hormone melatonin. The suggested functions of the pineal gland is that it inhibits reproductive functions, protects against damage by free radicals, and sets circadian rhythms. Identify the hormones produced by the pancreas and specify the functions of those hormones. The pancreas contains both exocrine and endocrine cells. Cells of the endocrine pancreas form clusters called pancreatic islets (islets of Langerhans). The pancreatic islets release insulin and glucagons. Insulin is released when blood glucose levels rise, and it stimulates glucose transport into and utilization by, peripheral tissues. Glucagon is released when blood glucose levels decline, and it stimulates glycogen breakdown, glucose synthesis and fatty acid release. Discuss the results of abnormal levels of pancreatic hormone production. When the pancreatic hormones produce abnormal levels of insulin and glucose it causes an individual to be diabetic. Diabetes mellitus is characterized by glucose concentration that is high enough to overwhelm the reabsorption capabilities of the kidneys. Glucose appears in the urine, and urine production generally becomes excessive. Describe the functions of the hormones produced by the kidneys, heart, thymus, testes, ovaries, and adipose tissue. Control of the heart, kidneys, thymus, gonads, and adipose tissue. The kidneys release erythropoietin and calcitriol into the red bone marrow, intestinal lining, bone and kidneys. All of the hormones releases are to stimulate red blood cell production and calcium and phosphate absorption and it also stimulates calcium ions from bone; inhibits PTH secretion. The heart controls the hormones natriuretic that targets the kidneys, hypothalamus and adrenal gland. These hormones increase water and salt loss at kidneys; decrease thirst; and suppress secretion of ADH and aldosterone. The adipose tissue contain two hormones that support to different functions, first is leptin which targets the hypothalamus for suppression of appetite; permissive effects on GnRH and gonadotropin synthesis. Second is resistin that targets cell throughout the body that suppresses insulin response. Last but not least are the gonads with the hormones androgens, inhibin, estrogen and progestin. All these hormones are targeted by the pituitary glands to support the reproductive organs in males and females. In males the interstitial cells of the testes produce androgens. Testosterone is the most important sex hormone in males. Sustentacular cells in the testes support the differentiation and physical maturation of sperm. Under FSH stimulation, these cells secrete the hormone inhibin, which inhibits the secretion of FSH at the anterior lobe. The female body develops oocytes in the follicles; follicle cells produce estrogens, especially estradiol. After ovulation, the remaining follicle cells reorganize into a corpus luteum. Those cells release a mixture of estrogens and progestins, especially progesterone. Explain how hormones interact to produce coordinated physiological responses. Hormones interact to produce coordinated physiological responses in four ways: 1. antagonistic (opposing) effects 2. synergistic (additive) effects 3. permissive effects, in which one hormone is necessary for another to produce its effect 4. integrative effects, in which hormones produce different, but complementary, results Identify the hormones that are especially important to normal growth, and discuss their roles. There are several hormones that are important for normal growth: GH, insulin, PTH, calcitriol, reproductive and thyroid hormones. The circulation concentrations of these hormones are regulated independently. Changes produce unique individual growth patterns. Growth Hormone (GH): effects are most apparent in children where GH supports muscular and skeletal development. In adults GH assists in the maintenance of normal blood glucose concentrations and in the mobilization of lipid reserves. Thyroid hormones: if these hormones are absent during fetal development or for the first year after birth, the nervous system will fail to develop normally and mental retardation will result. If T4 concentrations decline before puberty, normal skeletal development will not continue. Insulin: without insulin the passage of glucose and amino acids across cell membranes will be drastically reduced or eliminated. Parathyroid Hormone (PTH) and Calcitriol: promote the absorption of calcium salts for subsequent deposition in bone. Without adequate levels of both hormones, bones will be weak and flexible. Reproductive Hormones: the sex hormones (androgens in males, estrogens in females) stimulate cell growth and differentiation in their target tissues. Differential growth induced by each hormone accounts for gender-related differences in skeletal proportions and secondary sex characteristics. Define the general adaptation syndrome. Any condition that threatens homeostasis is a stress. Our bodies respond to a variety of stress-causing factors through the general adaptation syndrome (GAS), or stress response. The GAS can be divided into three phases: the alarm phase the resistance phase the exhaustion phase Reference page: S.Schaffer. Chapter 18. The endocrine system.
