Describe the roles performed by a modern Police Service in t essays
Describe the roles performed by a modern Police Service in t essays This assignment intends to examine the current structure of the Police Service operating in England and Wales, paying particular attention to the various roles of a modern Police Force within the wider criminal Justice System. Firstly, the assignment will look at how the Police Force has evolved and where the origins of the Service lie, and look also at how the roles and function of the Police Service have altered over the past three decades, finally summarising the positive and negative aspects of the current structure and role in comparison to the service provided at the beginning of the nineteenth century. The first Metropolitan Police Force was formed at the beginning of the nineteenth century, under the Conservative Government serving at the time. Sir Robert Peel, the then Home Secretary oversaw the imposition of the Metropolitan Force. There has been vast historical comment suggesting various different schools of thought as to why the Metropolitan Force was established at the time it was, and one such Whig Historian, Reith, argued that the idea of a Metropolitan Police Force was borne in order to control the increase of [the] menace of crime ( Reith, in Controlling Crime. 2002. pp 13). Reith discusses the formation of this Metropolitan Force as a solution to crime and disorder that he considered to be a growing problem during the 1820s. Reith argued that the Government initiative to create a Metropolitan Police Force in the countrys capital was a means of controlling the army of homeless children...who lived by stealing and begging, and as way of stopping the constant menace o f mob disorder, which Reith saw as a threat to the dignity of Parliament ( Reith, in Controlling Crime. 2002. pp 13). As an alternative explanation as to why the Metropolitan Police Force was formed, fellow Whig Historian, Storch comments on the idea of a Police Force as a greater tool ...

Determining the Costs of College
Determining the Costs of College How much does college cost? This question is tricky because it depends on the college you will be attending, as well as when you will be attending. Here are some important factors to consider. Private vs. Public The tuition at private colleges is more than double the tuition of a public college. According to the College Board, the cost of a years tuition in 2018-2019, plus room and board, averaged $36,890 for private colleges and $26,290 for public colleges. Inflation It doesnt matter is you will be attending a private or public university, the cost of tuition goes up every year. Many financial experts estimate that the cost of college will increase at approximately 6% each year over the next 10 years. Financial Aid Just thinking about the rising costs of college tuition is enough to make your head spin. Before worrying that you will never be able to afford a years worth of college tuition, let alone four years, consider these two words: financial aid. Financial aid is available to those who need it. And, the good news is that there is a lot of it. Grants, scholarships, student loans, and work-study programs, will help to cover the cost of college. All you have to do is educate yourself in regards to how aid works and how you can get it.

Essay Example The risks and benefits, the rights and wrongs, or the pros and cons of genetically modified food and science are global concerns in both public and private arenas (Adolphs, Hamilton and Nerlich, 58). In todayââ¬â¢s technological world however, GM crops and products play an important role in driving modernization and as such they are here to stay; as long as focus is not placed on future technological advancement instead of todayââ¬â¢s risks and disadvantages, and if research, assessment, controls and policies are adequately and stringently evidenced then the benefits, will eventually negate the risks. Martin Teitel, in his article entitled ââ¬ËUnsafe at any Seed?ââ¬â¢ argues against GM food claiming the argument that GM foods are better for the environment, farmers and consumers ââ¬Å"should be taken with a grain of saltâ⬠(1). He further purports that this new technology has grown too quickly with insufficient testing, has entered supermarket shelves too soon, and necessitates further research and an objective commission to verify and validate the safety of such foods prior to entering the market. This paper will argue in agreement of Teitelââ¬â¢s paper in some respects but will not concur with others. Although Teitel has put forward some pertinent points that are significant if biotechnology is to continue and develop, his argument falls short in that he fails to consider the debate from two perspectives ââ¬â that of the opponent and that of the advocate of GM foods ââ¬â and has remained steadfast on the side of opponents at the risk of sounding dogmatic and ill informed. The situation is not as black and white as Teitel paints it; within the developed world scientists are at odds in their convictions on measurement of risk, both for health and the environment. Many are convinced that assessments are not necessary or are too harsh, while

On Lung Cancer - Assignment Example These research findings are very important since they negate the long-held perception that nicotine is fundamentally the cause of lung cancer. The specialty of these research works is that they have separately found the effect of years of smoking and that if genetic variants on an individualââ¬â¢s risk of getting lung cancer. Knowledge of the results obtained from these studies may be utilized in the development of more effective drugs and treatment options for the smokers. ââ¬Å"We are all impatient for drugs that can cure cancer no matter when and where we find itâ⬠(Phelps, 2012). Findings of the research done by the team in Iceland also found that have specific gene variants even increases the addiction for nicotine in some smokers, which increases their susceptibility to getting lung cancer. ... ââ¬Å"It is imperative that government agencies, the research and funding community, health systems and insurers, community leaders, schools and families all take steps now to cut tobaccoââ¬â¢s rural roots [since more rural than urban population falls prey to it]â⬠(ââ¬Å"Cutting Tobaccoââ¬â¢s Rootsâ⬠). For those who continue taking the risk, drugs blocking nicotine might prove useful as nicotine is what triggers their chances of acquiring lung cancer. Nicotine in cigarettes increases the susceptibility of smokers with predisposition to lungs cancer to risk of this disease. I hate smoking and I have objective reasons for doing so. I totally agree with (Park) when she says, ââ¬Å"we already know the best way to prevent [lung cancer] - by not smoking in the first placeâ⬠(Park).

Determination of Ksp of Copper(II) Iodate by E.M.F. Measurement Essay Example for Free
Determination of Ksp of Copper(II) Iodate by E.M.F. Measurement Essay Introduction: Copper(II) iodate(V) ionizes weakly in water: Cu(IO3)2 + aq Cu2+(aq) + 2IO3-(aq) For a saturated solution of copper(II) iodate(V), concentration of IO3- ions doubles that of the Cu2+ (aq) ions, and Ksp of Cu(IO3)2(s) can be calculated by determining the concentration of Cu2+(aq) ion of a saturated Cu(IO3)2(aq). The e.m.f. of a galvanic cell consisting of a Zn(s)/Zn2+(aq) half-cell and another half-cell containing a copper strip in contact with a saturated solution of Cu(IO3)2(aq) is measured by a commercial DMM. Concentration of Cu2+(aq) is determined with reference to the EO values of the Zn(s)/Zn2+(aq) and the Cu(s)/Cu2+(aq) couples as well as the Nernst equation for a metal/metal ion half-cell: where n is the number of electrons transferred in the reduction process. ? Zn Zn2+ + 2e- Cu2+ + 2e- Cu ? n=2 For the Zn(s)/Zn2+(aq) half-cell, = -0.76V For the Cu(s)/Cu2+(aq) half-cell, Ecell = ER EL = {(+0.34) + 0.0295 log [Cu2+(aq)]} {(-0.76)} = (1.10) + 0.0295 log [Cu2+(aq)] When the voltage of the cell system is measured, the concentration of Cu2+ can be determined by the above equation. Therefore, the solubility product can be calculated by the above principle. Purposes: To determine the solubility product of copper(II) iodate(V) at room temperature and pressure by e.m.f. measurement. Apparatus and Reagents Used: Apparatus used: Well-plate; Plastic pipettes; Copper wire electrode; Zinc plate electrode; Digital multimeter (DMM); Connecting wires with crocodile clips; Filter paper strip, and Sand paper à ¯Ã ¿Ã ½1 à ¯Ã ¿Ã ½2 à ¯Ã ¿Ã ½1 à ¯Ã ¿Ã ½1 à ¯Ã ¿Ã ½1 à ¯Ã ¿Ã ½2 à ¯Ã ¿Ã ½1 Reagents used: 1M ZnSO4(aq); 0.3M KIO3(aq); 0.15M CuSO4(aq), and Saturated KNO3(aq) Chemical Reactions Involved: The equation of dissolution of copper(II) iodate(V): Cu(IO3)2(s) + aq Cu2+(aq) + 2IO3-(aq) The equation of redox reaction between Zn and Cu2+: Cu2+(aq) + Zn(s)Zn2+(aq) + Cu(s) Procedures: 1. 50 drops of 1M ZnSO4(aq) were placed into a well of the well-plate; 2. 25 drops of 0.3M KIO3(aq) were placed into an empty well next to the well containing the 1M ZnSO4(aq), by using a clean Jumbo pipette; 3. The plastic pipette used in step(2) was cleaned. By using the same plastic pipette, 25 drops of 0.15M CuSO4(aq) were added and stirred well with a micro-stirrer or toothpick. 5 minutes were waited to attain equilibrium; 4. The two wells were connected by a strip of filter paper moistened with saturated KNO3(aq); 5. A clean homemade copper wire electrode and a clean zinc plate electrode were placed into the well containing the pale blue suspension and the well containing the 1M ZnSO4(aq) respectively; 6. The prepared galvanic cell was connected to a DMM. The steady voltage developed was recorded. Observations: When the galvanic cell completed in step(5) was connected to the DMM, a steady voltage was developed. Data and results: Temperature of the aqueous solution = 26? E.m.f. of the cell formed by Zn(s)/Zn2+(aq, 1M) and Cu(s)/Cu(aq, saturated) = 0.997V Discussions: 1. The expression of the Ksp of copper(II) iodate(V) = [Cu2+(aq)]eqm [IO3-]2eqm 2. By the equation evaluated in the introduction, Ecell = (1.10) + 0.0295 log [Cu2+(aq)] = 0.997V 0.0295 log[Cu2+(aq)] = -0.103 log[Cu2+(aq)] = -3.492 ? [Cu2+(aq)]eqm = 3.225 à ¯Ã ¿Ã ½ 10-3 moldm-3 Concentration of Cu2+(aq) in the saturated pale blue suspension = 3.225 à ¯Ã ¿Ã ½ 10-3 moldm-3 3. By the equation of dissolution of copper(II) iodate(V), Cu(IO3)2(s) + aq Cu2+(aq) + 2IO3-(aq) [Cu2+(aq)] : [IO3-(aq)] = 1 : 2 ?[IO3-(aq)]eqm = 2 à ¯Ã ¿Ã ½ 3.225 à ¯Ã ¿Ã ½ 10-3 = 6.450 à ¯Ã ¿Ã ½ 10-3 moldm-3 Concentration of IO3-(aq) in the saturated pale blue suspension = 6.450 à ¯Ã ¿Ã ½ 10-3 moldm-3 4. The value for Ksp of Cu(IO3)2 = [Cu2+(aq)]eqm [IO3-]2eqm = (3.225 à ¯Ã ¿Ã ½ 10-3) à ¯Ã ¿Ã ½ (6.450 à ¯Ã ¿Ã ½ 10-3)2 = 1.34 à ¯Ã ¿Ã ½ 10-10 mol3dm-9 5. From the data of the Faculty of Chemistry and Technology, University of Split, the literature value of Ksp of Cu(IO3)2 is 6.94 à ¯Ã ¿Ã ½ 10-8 mol3dm-9 [1]. Obviously, the literature value was much larger than the experimental value. The discrepancy came from several reasons: 1 The experimental temperature was 26?, which was different from the expected room temperature 25?. As temperature is the main factor of Ksp, the discrepancy of Ksp was caused by the difference of temperature; 2 The low quality of copper and zinc electrode may affected the e.m.f. taken from the DMM, so the Ksp result was also affected; 3 The concentration of solutions prepared may be different with the expected value. The e.m.f. given out may not equal to the theoretical values, so the Ksp obtained may be different. Conclusion: By the e.m.f. method, the solubility product of copper(II) iodate(V) at room temperature and pressure was determined. Ksp for = 1.34 à ¯Ã ¿Ã ½ 10-10 mol3dm-9 Reference: [1] : Solubility Product Constants, Faculty of Chemistry and Technology, University of Split http://www.ktf-split.hr/periodni/en/abc/kpt.html

Never Lose Hope :: essays research papers
Never Lose Hope William Blake, born on November 28, 1757, in London is one of the greatest English poets. His work is studied today all over the world. One of Blakeââ¬â¢s poems, ââ¬Å"The Chimney Sweeperâ⬠, shows many signs of immortality. In this poem, immortality can only be reached by maintaining hope in a hopeless world and embracing happiness. An example of this is line 20: ââ¬Å"Heââ¬â¢d have God for his father, and never want joyâ⬠. Immortality is something people have chased for years and have never been able to capture. In Websterââ¬â¢s dictionary, immortality is stated as, ââ¬Å"Not mortal, deathless, living or lasting forever.â⬠In ââ¬Å"The Chimney Sweeperâ⬠, Blake saw immortality in a different sense than Webster states. Blake saw immortality as happiness throughout life and the importance of hope. à à à à à ââ¬Å"The Chimney Sweeperâ⬠is a great title for Blakeââ¬â¢s poem. The title is a symbol representing the harsh life of a chimney sweeper and his life as a child. He states, ââ¬Å"When my mother died I was very young, and my father sold me while yet my tongueâ⬠, (ln 1-2). This is saying that his mother died when he was young and his father gave him up. Blakeââ¬â¢s unhappiness resembles being mortal in a sense that his unhappiness is like being dead. Blake has two meanings when he says, ââ¬Å"So your chimneyââ¬â¢s I sweep, and in soot I sleepâ⬠, (ln 4). This line denotes that he is an adult now with the responsibility of being a chimney sweeper. Blake is really saying that his childhood was terrible like the work of a chimney sweeper. Now Blake introduces a new character into the poem, which is Tom Dacre (ln 5). In the second stanza, Blake is stating the mortality, or unhappiness of Tom. The authorââ¬â¢s tone changes for a moment in stanza two when he says ââ¬Å"Hush, Tom! never mind it, for when your headââ¬â¢s bare, the soot cannot spoil your white hairâ⬠, (ln 7-8). The author has two meanings in these lines. The obvious is that he canââ¬â¢t have hair for the fact that his hair would be full of soot. The tone change comes in where the meaning is not so obvious. The tone up to line six is mournful. Lines seven and eight also have a mournful tone in the obvious state. They connote that Tom needs to keep his head up and not let his job get to him, or simply to keep hope alive.

Lives of the Saints Essay
Summary: Chapter 1 In the opening of the chapter, the main character Vittorio describes the story that the book is written about. It has a beginning that occurred on a hot July day in the year 1960 in Vittorioââ¬â¢s home town of Valle de Sole, when his mother, Christina got bit by a snake. Vittorio describes his city as to have no holy places, ancient cites or ruins; forgotten and unsung, just like hundreds of villages spread throughout Italy. Vittorio describes how his father immigrated to America almost four years ago when Vittorio was barely three years old. His grandfather was left crippled from the war when a horse crushed his foot and he was injured by a grenade. That day, his mother slipped out of the house making him promise that he would read his school books. Vittorioââ¬â¢s attendance at school was not very regular because he would spend much of class time wondering to the top of Colle di Papa or down the river with his friend Fabrizio and sharing cigarettes that Fabrizio had stole from his father. Vittorio was sitting on his porch reading math books when he dose off. He was awakened by a muffled shout coming from the stable. Vittorio ran to the stable and stopped short at the bottom of the steps and peeked through the crack in the door. Inside he saw a green snake which slipped through the cracks of the stable and into the tomato garden. While Vittorio was watching the snake, the barn door opened, and a man with blue eyes swooped out of the stable. After Vittorio went inside the stable, he saw his mother pouring water into the pigsââ¬â¢ trough as though nothing has happened. Vittorio tells his mother that he heard a man screm and when she asked him what he saw, Vittorio replied that he didnt see anything. He then told her that she has blood on her ankle. In the conclusion of the chapter, Christina tells Vittorio to run up to Di Lucciââ¬â¢s and tell him to bring a car because she had been bitten by a snake.

Debt financing is describe as the type of financing we receive from a traditional bank loan and equity financing is describes as the financing we receive from venture capital into our business from outside investors.Therefore, the benefit of debt financing is refer to itââ¬â¢s limited in amount and we will pay down the debt over time to a zero sum balance without any further obligation to the lender and the down stroke to debt fin ancing is to define that traditional lenders will take a hard look at our business including how long it has been in existence, income from operation, expenses and it will require hard assets for collateral for the loan. Moreover, those lenders will most certainly want us to personally guarantee for the repayments of the loan. Another disadvantage of debt financing is that our organization will be burdened with some other type of regular payment which is usually a monthly payment which depending on the terms and conditions of the financing and this can absorbs critical cash flow, especially those individual or partners with small business.Besides that, the benefit of equity financing or venture capital is that we will be also receiving money in exchange for equity in our business in the form of stock or some other form of equity like percentage of income or gross net sales. A fundamental benefit of this type of the equity financing is to define there is no monthly payment requiremen t to investors. Instead, we are giving up ownership interest, most often, permanently. Furthermore, the traditional lenders, banks for example, will look at our business much slightly different than venture capitalist. Bankers want a zero-risk or near-zero risk position when they provide financing and will rely almost completely on the operating economics of the business with little regard for potential future growth.Thus, they want to see strong cash flow backed up by hard assets before they do a deal with the ingredients that most small business lack or they wouldnââ¬â¢t be seeking for financing. Eventually, the venture capitalist is on the other hand which they tend to consider the management team and the potential future growth of the business more heavily than actual operating numbers, especially for those with small business with large potential but few sales and little or no operating history. Although these two types of lender is vary in their approaching to analyzing a b usiness for funding, we can also be sure that careful examination of our business will be conducted.

Every AP Calculus AB Practice Test Available Free and Official
Every AP Calculus AB Practice Test Available Free and Official SAT / ACT Prep Online Guides and Tips One of the best ways to prepare for the AP Calculus AB exam, as well as stay on top of lessons in class throughout the year, is to take regular practice tests.Taking practice tests lets you estimate how well youââ¬â¢ll do on the AP exam, shows you the areas you need to focus your studies on, and helps you become more comfortable with the format of the AP exam. There are a ton of ABCalc practice tests available, however; not all of them are created equally. Taking a poorly written practice test can give you a false idea of what the real AP exam will be like and cause you to study the wrong things. You can avoid those problems by reading this guide to AP Calculus AB practice tests. Iââ¬â¢ll go through every AP Calculus AB practice exam thatââ¬â¢s available, tell you which are highest quality, and explain how you should use practice tests when preparing for the AP exam as well as throughout the year.

Whether you need help with science, math, English, social science, or more, we've got you covered. Get better grades today with PrepScholar Tutors. Official AP Calculus AB Practice Tests Official practice exams (those developed by the College Board) are always the best to use because you can be sure theyââ¬â¢ll be an accurate representation of the real AP exam. There are three types of official practice resources, and each is explained below. Complete Practice Tests The College Board has released two complete exams from prior administrations of the AP Calculus AB exam. The tests are from 1988 and 1998. The 1988 test has an answer key included; however, for some reason, the 1998 exam does not. The College Board provided answers for the free-response questions in a separate document, but there is no official answer key available for the 1998 exam's multiple-choice section. The answer key linked below is unofficial, but no one has publicly disagreed with any of the answers, so itââ¬â¢s highly likely that itââ¬â¢s correct. 1988 AP Calculus AB Released Exam 1998 AP Calculus AB Released Exam Answer Key for 1998 Multiple-Choice Questions Answer Key for 1998 Free-Response Questions Because these exams are from a while back, they both have some format differences compared to the current AP Calculus AB exam. The AP Calculus AB exam is 3 hours and 15 minutes long and has two sections. Both of these sections are divided into two parts.For reference, hereââ¬â¢s the current format of the exam: Multiple-Choice Section 45 questions total 1 hour 45 minutes total Worth 50% of your total score Part A: 30 questions 55 minutes long No calculator allowed Part B: 15 questions 50 minutes long Calculator permitted Free-Response Section Six questions total 1 hour 30 minutes total Worth 50% of your total score Part A: Two questions 30 minutes long Calculator permitted Part B: Four questions 60 minutes long No calculator allowed You can only use a calculator for certain sections of the AP exam. Both released exams have the same total number of multiple-choice and free-response questions as the current exam. However, the 1998 test does not have separate parts for the free-response section, and students were allowed to use a calculator to answer all six questions. Neither the multiple-choice nor the free-response sections ofthe 1988 exam were separated into different parts, and students were allowed to use their calculator for the entire exam. The multiple-choice section was also only 90 minutes long, instead of 105 minutes. When you take these exams for practice, itââ¬â¢s not worth the time and effort needed to try and figure out which questions you wouldnââ¬â¢t be allowed to solve with a calculator today. Instead, take the tests with the calculator and timing rules that were in place when the tests were administered. These variations between current and past exams do mean that these two complete released exams donââ¬â¢t give quite as accurate a representation of the current AP exam as the complete released exams for other AP subjects do. However, they are still very useful because they cover the same content and are worded the same way as the current exam. Towards the end of this guide Iââ¬â¢ll explain exactly how to use these resources and others. AP Calculus AB Multiple-Choice Sample Questions The College Board often reuses multiple-choice questions for multiple exams, so there are typically few official multiple-choice problems available for any AP exam, AP Calculus AB included. Besides the complete practice tests discussedabove, thereare no full official multiple-choice sections available, but you can check out these official sample questions for Calculus AB. (The questions start on page 5, and there are Calculus BC questions listed after the AB questions; be sure youââ¬â¢re not accidentally looking at those.)This document contains 16 multiple-choice problems, along with answers and the major skills each question tests. There are also two free-response questions. AP Calculus ABFree-Response Sample Questions Fortunately, there are more official free-response questions available and, since they are recent, they provide you with a very accurate idea of what to expect on the real exam. The College Board has released free-response questions from 2002-2017, along with scoring guidelines for each set of questions. These are a great resource, and you should definitely make use of them during your review. Khan Academy Resources Khan Academy has recently partnered with the College Board to provide study resources for the PSAT, SAT, and some AP exams. This includes study resources for AB Calc. On Khan Academyââ¬â¢s website, there are explanation videos for several dozen previously administered questions, both multiple choice and free response. These videos can be particularly helpful if youââ¬â¢ve gotten stuck on one of the official practice problems or if you just want to learn step-by-step how to solve a particular problem. Unofficial AP Calculus AB Practice Tests and Quizzes While not developed by the College Board, unofficial practice resources can still be very useful for your studying, particularly because there are so many resources available. For each resource listed below, I explain what is offered as well as how you should make use of the resource. They are roughly listed from highest quality to lowest quality. Barronââ¬â¢s Barronââ¬â¢s has a complete and free practice test that you can take in timed or untimed mode. The multiple-choice section will be automatically scored, and there are answer explanations for the free-response section so you can self-score. This is a high-quality practice exam with questions that have a similar format and cover the same topics as the real AP exam. Youââ¬â¢ll definitely want to use it in your review (more on how to do that in the next section). Shmoop Shmoop is the only resource listed in this guide that requires a fee to access any of its resources. Paying its fee of $24.68 a month gets you access to a diagnostic exam, as well as eight complete practice tests and additional practice questions. It also gets to access to Shmoopââ¬â¢s study materials for other AP exams, as well as the SAT and ACT. Varsity Tutors Varsity Tutors has a collection of three diagnostic tests and 139 short practice quizzes, organized by topic, such as the chain rule and finding the second derivative of a function. Difficulty levels are also given for each of the quizzes. The diagnostic tests are 40-45 questions long (all multiple-choice). They pretty closely represent what questions from the actual AP exam are like, and, as a bonus, the score results show you how well you did in each topic area so you can focus your future studying on the areas you need the most work in. However, these diagnostic tests donââ¬â¢t have calculator and no calculator sections. Albert This site organizes quizzes into the three Big Ideas of Calculus AB, as well as more specific tags you can select (you donââ¬â¢t need to worry about the Series quizzes, thatââ¬â¢s just for BC Calc). After creating a free account you can access their hundreds of practice questions (some of the more challenging questions require a paid account). Questions are ranked as easy, moderate, or difficult, they are not timed, and you see the correct answer (plus a detailed explanation) after you answer each question. GetaFive GetaFive offers 182 Calculus AB practice questions, along with 54 review lessons. This is more of an online review course rather than just practice questions, so the questions themselves are spread across the lessons, but if youââ¬â¢re looking for more in-depth explanations of topics, you may find it useful to watch the videos and then answer the accompanying questions. 4Tests This site has a 50-question multiple-choice test. The questions typically easier and more basic than those youââ¬â¢d find on the actual AP exam, but if youââ¬â¢re just starting your review or want to brush up on the basics, this can be a good resource to use. Free Test Online This site has four short quizzes, each 5-8 questions long, along with answer explanations. Two quizzes are multiple-choice, and two are free-response. The free-response questions are much shorter than what youââ¬â¢d encounter on the real AP exam, but you can treat them like slightly more involved multiple-choice questions. The quizzes arenââ¬â¢t long enough for an in-depth practice session, but, unlike many of the other practice materials linked here, they also separate the quizzes on whether or not youââ¬â¢re allowed a calculator. Analyze Math This is a 20-question multiple-choice quiz. The questions are a bit overly simplistic, and itââ¬â¢s not automatically graded, but if youââ¬â¢re just looking for a quick study session, this fits the bill. SparkNotes This is a short quiz, and, unfortunately, itââ¬â¢s not very high-quality. The questions are pretty basic and not nearly as complex or as in-depth as the ones youââ¬â¢ll find on the AP exam. Additionally, the format of this quiz is very poor, and it can be difficult to read. I wouldnââ¬â¢t recommend using this quiz unless youââ¬â¢re really desperate for review questions or you need a very basic quiz to get you started with your review.

How to Use These AP Calculus AB Practice Tests Knowing how to use each of these practice exams and quizzes will make your studying much more effective, as well as prepare you for what the real AP Calculus AB exam will involve. Below is a guide for when and how to use the resources, organized by semester. First Semester During your first semester of Calc AB, you donââ¬â¢t know enough material for it to be useful to take a complete practice exam. Therefore, you should spend this semester answering quizzes and free-response questions on topics youââ¬â¢ve already covered. Youââ¬â¢ll probably want to begin answering practice questions about halfway through the semester. Free-Response Practice For free-response questions, use the official released free-response questions in the Official Resources section. Look through them to find questions you can answer based on what youââ¬â¢ve already learned. Itââ¬â¢s best if you can take a group of them (up to six) together at a time in order to get the most realistic preparation for the real AP exam. It also helps to time yourself when answering these questions, particularly as it gets later in the year. On the real AP exam, youââ¬â¢ll have about 15 minutes to answer each free-response question, so try to answer practice questions under those same time restrictions. Multiple-Choice Practice For multiple-choice practice, take unofficial quizzes that letyou choose the subject(s) you want to be tested on. This will allow you to review content youââ¬â¢ve already learned and not have to answer questions on material you havenââ¬â¢t covered yet. The best resources for this are Albert and Varsity Tutorsbecause their quizzes are clearly broken up by specific subject. Sometimes the numbers can get overwhelming. Don't forget to take a break every now and then. Second Semester Second semester is when you can begin to take complete practice exams and continuing to review content youââ¬â¢ve learned throughout the year. Step 1: Take and Score Your First Complete Practice Exam Early on in this semester, when you have covered a majority of the content you need to know for the AP exam, take your first complete practice exam. This test should be taken in one sitting and with official timing rules (see how the AP test is formatted above). For this first practice test, I recommend using the Barronââ¬â¢s exam and saving the official practice exams for down the line. After you take this practice test, correct the exam and see what score you earned on the test. This is a good time to set a score goal if you havenââ¬â¢t already. The minimum score you should be aiming for is a 3, since this is the lowest passing score. However, if you scored a 3 or higher on this first practice exam, itââ¬â¢s a good idea to set your goal score even higher, to a 4 or 5. Getting a higher score on the AP Calculus AB exam looks more impressive to colleges, and it can sometimes get you more college credit. Step 2: Analyze Your Score Results After youââ¬â¢ve figured out your score, look over each problem you answered incorrectly and try to figure out why you got the question wrong. As youââ¬â¢re doing this, look for patterns in your results. Are you finding that you got a lot of questions on antiderivatives wrong? Did you do well on multiple choice but struggled with free response? Did you get slowed down by questions you couldnââ¬â¢t use a calculator to answer? Figuring out which problems you got wrong and why is the best way to stop repeating your mistakes and begin to make significant improvements. Donââ¬â¢t be tempted to skip this step! Step 3: Focus Your Studying on Weak Areas You should now have a good idea of what subject areas or skillsyou need to work on in order to raise your score.If there are specific content areas you need to work on, review them by going over your notes, reading a review book, and answering multiple-choice and free-response questions that focus specifically on those topics. If youââ¬â¢re struggling with your test-taking techniques, for example, running out of time on the exam or misreading questions, the best way to combat these issues is to answer a lot of practice questions under realistic testing conditions. Take timed quizzes or time yourself for quizzes that arenââ¬â¢t automatically timed. (On the real exam, youââ¬â¢ll get about two minutes for multiple-choice questions you canââ¬â¢t use a calculator to solve, a little more than three minutes for multiple-choice questions where you can use a calculator, and 15 minutes per free-response question.) Taking multiple practice quizzes and tests will help you become more familiar with the pacing needed for the AP exam. Step 4: Take and Score Another Practice Exam After youââ¬â¢ve identified your weak areas and spent time to improve them, itââ¬â¢s time to see how all your hard work paid off. Take and score another complete practice exam, timed and taken in one sitting. Iââ¬â¢d recommend using either an official released practice exam or, if you want more recently-created questions, creating your own practice test by combining a set of unofficial multiple-choice questions (such as the Varsity Tutors or 4Testsexam) with a set of official free-response questions. If you choose the second option, you should have a total of 45 multiple-choice questions for the first part of the exam. As with the first test, this should be taken timed and in one sitting. When you take this second practice exam, remember that it wonââ¬â¢t be formatted exactly the same way as the real AP test, wherethe multiple-choice and free-response sections will both be broken into two parts,only one of which you can use a calculator on. Step 5: Review Your Results to Determine Your Future Study Plan Now youââ¬â¢re able to see how much youââ¬â¢ve improved, and in which areas, since you took your first complete practice exam.If youââ¬â¢ve made improvements and have reached or are close to your target score, you may only need to do some light studying from now until the AP exam. However, if you havenââ¬â¢t made much improvement, or youââ¬â¢re still far from your score goal, youââ¬â¢ll need to analyze the way youââ¬â¢ve been reviewing and think of ways to improve. The most common reason for not improving is not actively studying, butonly passively leafing through your notes or reviewing missed questions. Even though it may seem to take a while, in the long run, carefully analyzing why you made the mistakes you did and devising ways to improve is really the only significant way to raiseyour score. As youââ¬â¢re studying, be sure to really understand exactly where you made a mistake for every practice question you answer incorrectly. Also, when youââ¬â¢re reviewing notes, pause every few minutes and mentally go over what you just learned to make sure youââ¬â¢re really retaining the information. You can repeat these steps as many times as you need to in order to make improvements and reach your target score. Studying WithAP Calculus AB Practice Exams: Key Tips It would be difficult to score well on the AP Calculus AB exam without completing anypractice exams.Official resources are the best to use, but there are plenty of high-quality unofficial quizzes and tests out there as well. During yourfirst semester, you should focus on answering free-response and multiple-choice questions on topics youââ¬â¢ve already covered in class. During your second semester, follow these steps: Take and score your first complete practice exam Analyze your score results Focus your studying on weak areas Take and score another complete practice exam Review your results to determine your future study plan What's Next?

Study of Human Behavior 10 Facts That Will Make You Fall in Love with the Course Study of Human Behavior: 10 Facts That Will Make You Fall in Love with the Course Even the words ââ¬Å"human behaviorâ⬠make you yawn. But, it just sounds so dry and boring. Actually, youââ¬â¢re wrong. The study of human behavior is truly fascinating. The way we behave is unpredictable, weird, and sometimes wonderful. Here are 10 fun facts that will make you hungry to learn more. High levels of testosterone have been linked to pleasure in the expression of anger towards others. We all know that testosterone can make us more aggressive, but now the reason is clear. The expression of anger gives some of us pleasure similar to what we feel when having sex. After you die, your brain remains alive for 7 minutes replaying all the memories from your life. So it turns out that you really do ââ¬Å"see your life flash before your eyesâ⬠when dying. Spooky, isnââ¬â¢t it? Studies have confirmed that publicly stating a goal to others makes it less likely that you will succeed. The added pressure of the expectations of others causes you to lose your motivation. So next New Yearââ¬â¢s, try writing your resolutions down privately instead of posting them publicly on social media and see what a difference it makes. It has been found that people with low self-esteem are more likely to engage in acts to purposely humiliate others. It turns out Mom was right all along. Bullies really do just feel bad about themselves. When a person lies, he or she has a tendency to look to the left or upwards. Anywhere but directly in the eyes of the person theyââ¬â¢re talking to! The last person you are thinking about before you fall asleep is either a root cause of happiness or pain in your life. Perhaps this also explains why they so frequently show up in your dreams at night, too. When we have negative opinions about others, we really believe that these opinions are true and unbiased. That teacher is just incompetent and everyone knows it. The fact that he gave you a failing grade on your last paper has nothing to do with it. Intelligent women are more likely to remain single. It turns out that women with a higher IQ usually prefer being alone to being with the wrong people. So, if youââ¬â¢re a girl who has been single for a long time, it could just mean that youââ¬â¢re smarter than an average one. When listening to boring speeches, we are constantly rewriting them in our minds to make them more interesting. Itââ¬â¢s our own inner defense mechanism to help keep us focused when a lecturer drones on and on. And most of the time, we donââ¬â¢t even realize that weââ¬â¢re doing it. Physical sensations directly affect our behavior. For example, if an object feels physically heavy, we associate it with a feeling of seriousness. And it has been shown that contact with nature helps us cope with the stress better. Want to learn more intriguing facts about human behavior? There are plenty of them, and we guarantee that as you continue studying them, you will be endlessly fascinated and hungry to learn even more.

Windber Medical Center Essay Example | Topics and Well Written Essays - 750 words
Windber Medical Center - Essay Example Adherence to staff hierarchy and unquestioned physician authority were the norm. However, with the demise of the coal industry, Windber Medical Center lost its key clientele, influence and revenue dipped. To make matters worse Congress enacted the Balanced Budget Amendment Act that changed how reimbursements would be made to small, nonteaching and non-rural hospitals such as Windber. This meant that Windber would have to find a way to be more competitive in order to attract more patients, government funding and funding from other third parties. Diagnosis: What problems was Windber Medical Center facing? According to the report from Ernst and Young, Windber was not making enough money and it faced an imminent demise in five yearsââ¬â¢ time because of the changes in insurance reimbursements, changes in government reimbursements and heightened competition due to increased penetration of managed care products in the market. Furthermore, Windber was located in an area where the populat ion was migrating out of thus reducing the size of its market. However, the root cause of Windberââ¬â¢s problems was that it operated in an archaic system that saw patients as ââ¬Å"disruptionsâ⬠rather than as customers.... The new president charged with implementing the change made appointments to meet with each employee and members of the medical staff individually. This assessment method was effective because it enabled the president to understand the organizationââ¬â¢s culture fully as well as its influence on each employee. A similar tactic with the medical staff was not successful, however out of its failure the president learnt about the hidden, informal power structure. He learnt that there were sixteen physicians who were the nucleus of power among the medical staff. Out of this assessment it was also noted that senior managers who believed in the power of physicians sided with them on every decision. Design: What is the desired state or goal? The ultimate aim of the change effort at Windber Medical Center was to make patient-centered care the organizationââ¬â¢s premier priority. To support this goal the organization also committed to providing a loving, nurturing environment to patients and their families as well as to addressing all patient and patient family issues quickly and efficiently. Implementation: What interventions were employed to reach this goal? Four techniques were adopted by management to advance the change effort: training, rewards, dismissals, feedback sessions and media communications. Trainings were done through: (1) peer-to-peer where four employees from different departments were trained offsite and brought back to train their peers; (2) hiring of a management consultant; (3) taking head of departments on tours to learn new models of care; and (4) annual refresher courses. Rewards were given to employees caught caring and this motivated others to do the same. After three years nearly 10 percent of the workforce

Learning and Development Essay Example | Topics and Well Written Essays - 3250 words
Learning and Development - Essay Example This report has recommended a multi-tiered and large-scale structural change to the Mumbai, India call centre. The first stage of the change involves the implementation of a training program. The next stage implements employee and customer evaluation practices that establish employee raises, as well as employees who can assume supervisory positions. While statistical models are greatly implemented during this phase, the next evaluative phase implements qualitative research methods to identify individuals for career counseling practices. These individuals will receive career counseling and then be given the option to receive higher levels education and then an upper level management or executive position with Acornââ¬â¢s operations in the United Kingdom. Finally, the report has demonstrated that human resources contribute to both competitive advantage and business strategy. Introduction Organizational culture and behavior spans a wide array of elements and concerns. One witnesses a great many elements related to organizational concerns in the Acorn call centre that was recently opened in Mumbai, India. Opened in 2003 the Acorn India call centre is an off-shoot of the companyââ¬â¢s main United Kingdom operations. While some cultural elements were considered in establishing this centre, including voice and accent training and cultural awareness, it is clear that there is a degree of dissonance between practice and perception. What has emerged is an organization that is experiencing high turnaround and an organizational culture that feels they are not a part of the main United Kingdom operations. Some of the most prominent theories have considered the nature of organizations as conforming to trends and values within the specific institutional environment Leong (1993, p. 42). Referred to an institutional theory this perspective offers an overarching perspective on organizational culture Leong (1993, p. 42). In terms of establishing organizational culture itâ⠬â¢s recognized that such elements are established both within the employee community as well as in the structure the management and executives establish Leong (1993, p. 42). Within the context of Acorn institutional challenges have emerged as the company structure in the United Kingdom has not applied readily to its Mumbia, India operations. This research advances with the overarching contextual recognition that because of this organizational culture major changes needed to be implemented in relation to learning and development and career management. Specific considerations are given to the organizationââ¬â¢s training programs, demographics, and in-built career advancement practices. Analysis Learning and Training While career elements constitute perhaps the greatest focus for needed organizational change at Acorn, more foundationally staff training constitutes a major area of concern. Just as Acorn has failed to establish a career management program the organization has also fallen short in establishing adequate training mechanisms. One of the central thorough-puts of this analysis then is the recognition that before Acorn has the necessary corporate infrastructure to implement the career system that will satisfy their employees at the Mumbai call centre it must first establish a
