The Circulatory System Essay Example

The Circulatory System Essay Example The Circulatory System Paper The Circulatory System Paper General Functions   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The circulatory system is the body’s main transport network and cooling system (De Graff, 1998). The human body needs many external substances to survive. We need air, food, and water. However, these substances are not readily absorbed by the body through initial intake. For example, food that is eaten and digested is not yet used to fuel the body’s billions of cells. The nutrients that have been processed need to be transported to each cell in the body in order for them to be used. This is one of the jobs of the circulatory system. The circulatory system is tasked with carrying the important substances that the body needs where they are needed (Hillendale Health, 2007). Furthermore, the system is also responsible for carrying some of the wastes from the cells such as carbon dioxide, away from the cells to be expelled by the body (Delos Johnson, 2006). This cycle of carrying nutrients to body cells and carrying wastes from th em is a way by which the system contributes to the maintenance of physiological homeostasis. Another way that it contributes to homeostasis is by helping maintain the temperature of the body. Without oxygen to burn, the cells in the body will become cold and eventually die (Delos Johnson, 2006). Thus, oxygenated blood carries oxygen to the cells and releases it in order to maintain homeostatic temperature. Last but not the least, the circulatory system also maintains homeostasis by fighting off outside threats that have infiltrated the body. White blood cells which also travel through the system fight back diseases and help keep the body healthy and they need the circulatory system for them to be able to reach the places in the body where particular bacteria are doing damage (Delos Johnson, 2007). Interactions with other organ systems   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   When we eat food or drink water, it enters our body through our digestive system and is processed in the stomach. Afterwards, the processed food is transported through the small intestines where it is further digested. The small intestine’s inner walls are covered with microscopic finger-like projections called villi which are primarily responsible for taking the nutrients from the digested food and transferring them to the bloodstream where they are carried to the rest of the body (Maton et. al., 1993). Thus, the digestive system and the circulatory system work closely together to nourish the body with food and drink. The circulatory system also works closely with the respiratory system. We take in air through our nose and from there it travels to our lungs. From there, pulmonary arteries which are a part of the circulatory system carries oxygen-depleted blood to absorb more oxygen while releasing the carbon dioxide that it has accumulated from the cells that it delivered nutrients to (Maton et. al., 1993). Of course, the circulatory system takes blood containing nutrients and oxygen to other organ systems of the body in order to enable them to continue functioning. The blood carries nutrients to our muscles, our sensory organs, our brain, and all other parts of our body that need it (Maton, 2003). Parts and functions The Heart   It is a powerful muscle that pumps the blood through the entire circulatory system (Hillendale Health, 2007). The Blood It is the main substance that flows throughout the circulatory system. There are red blood cells and white blood cells that both travel through the circulatory system (Hillendale Health, 2007). Plasma which is the liquid part of the blood carries both these blood cells through the system (Hillendale Health, 2007). The red blood cells carry nutrients from the small intestine and oxygen from the lungs to the cells all over the body (Hillendale Health, 2007). They are also the ones that carry carbon dioxide away from body cells and back to the lungs to be released as waste (Hillendale Health, 2007). The white blood cells travel to areas where harmful germs are infecting body cells and fight those foreign elements to keep the body healthy (Hillendale Health, 2007). There are also platelets found in the bloodstream which acts to help stop bleeding whenever the body gets wounded (Hillendale Health, 2007). For example, whenever we cut ourselves on some sharp object and bleed, the platelets stick to where we cut ourselves and attract more platelets to do the same. This plugs out the wound so that the bleeding stops. The Blood Vessels The blood vessels are the tubes where the blood passes through. There are three types of blood vessels which are arteries, veins, and capillaries (Hillendale Health, 2007). The arteries are blood vessels that carrying oxygenated blood away from the heart while veins carry blood back to the heart (Hillendale Health, 2007). Capillaries are very tiny blood vessels that serve as connections between arteries and veins (Hillendale Health, 2007). The Heart: A closer look   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The human heart is found in the middle of the thorax with its largest part slightly situated to the left just beneath the breastbone (Maton et. al., 1993). It is a mesh of muscle cells that are joined together by contiguous cytoplasmic bridges (Maton et. al., 1993). Tissues found on the heart’s walls are unique because they have qualities both of smooth muscle tissues and skeletal muscle tissues. The heart is covered by a protective sac called the pericardium (Maton et. al., 1993). The pericardium itself is composed of two parts. The fibrous pericardium is made of dense fibrous connective tissue that serves as the heart’s outer protection while the serous pericardium contains fluid that eases friction generated by heart contractions thus protecting the heart from friction caused by its own beating (Maton et. al., 1993). The right atrium is situated on the right side of the heart where the veins carrying deoxygenated blood are found. This is so that the right atrium can collect the deoxygenated blood and pass it through the heart which pumps it by the right ventricle to the lungs to be oxygenated once more (Maton et. al., 1993). After the blood is oxygenated by the lungs, it goes back to the heart through the left atrium and is pumped by the heart through the left ventricle to the rest of the body. It should be noted that the muscle wall that surrounds the left ventricle is thicker than the wall surrounding the right ventricle. This is because it is harder to pump blood to the rest of the body than to just pump it to the lungs and back (Maton et. al., 1993). Hence, thicker muscle means that the left ventricle is more powerful in pumping blood than the right ventricle. Hypertensive heart disease   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This diseases pertains to complications caused by arterial hypertension that affects the heart (eMedicine, 2007). Arterial hypertension which is more commonly known as high blood pressure is a condition wherein the pressure of the blood being pumped through the circulatory system is steadily increasing (eMedicine, 2007). This happens due to a variety of factors. Excessive intake of fat can clog up arteries and thus make it more difficult for blood to pass through. Thus, this makes the pressure of blood passing through the arteries increase. Because of the heightened pressure, the arterial walls are subjected to greater strain (Lip et. al., 2000). This can be imagined by visualizing a hose whose channel has been partially blocked. Fluid passing through that hose exerts more pressure on the hose walls and threatens to rupture the hose. In the same way, too much clogging in the arteries can cause pressure to build so much that it could ruptur e the arteries. Once this condition is elevated to dangerous levels, the heart gets affected by the imbalance in the pressure and hypertensive heart disease is developed (Lip et. al., 2000). The disease causes the heart to be strained more and more and may eventually cause it to breakdown and fail. The pressure can also burst blood vessels which can also damage the system. People suffering from this disease are easily fatigued due to the excessive work that the heart is coping with from the increased blood pressure (eMedicine, 2007). They would also have an irregular pulse, have difficulty sleeping, and feel a greater need to urinate at night (eMedicine 2007). If not treated with appropriate medicine, proper exercise and a good diet, hypertensive heart disease can lead death and is in fact one of the leading causes of death in the country (eMedicine, 2007).

King George III Biography

King George III Biography George III was King of Great Britain and King of Ireland during the American Revolution. Much of his reign, which lasted from 1760 to 1820, was colored by his ongoing problems with mental illness. During the last decade of his life, he was incapacitated to the degree that his eldest son ruled as Prince Regent, giving name to the Regency Era. Fast Facts: King George III Full Name:  George William FrederickKnown For:  King of Great Britain and Ireland during the American Revolution, suffered from acute and debilitating bouts of mental illnessBorn:  June 4, 1738 in London, EnglandDied:  January 29, 1820 in London, EnglandSpouses Name: Sophia Charlotte of Mecklenburg-StrelitzChildren: 15 Early Years Born June 4, 1738, George William Frederick was the grandson of Great Britain’s King George II. His father, Frederick, the Prince of Wales, though estranged from the king, was still the heir apparent to the throne. George’s mother, Princess Augusta of Saxe-Goethe, was the daughter of a Hanoverian duke. Although sickly as a child- George was born two months prematurely- he soon grew stronger, and he and his younger brother Prince Edward moved with their parents to the family home in London’s exclusive Leicester Square. The boys were educated by private tutors, as was common for the children of royalty. Young George was precocious, and he could read and write several languages fluently, as well as discuss politics, science, and history, by the time he was an adolescent. Heritage Images / Getty Images In 1751, when George was thirteen, his father, the Prince of Wales, died unexpectedly, following a pulmonary embolism. Suddenly, George became the Duke of Edinburgh and the heir apparent to the British crown; within three weeks, his grandfather made him Prince of Wales. In 1760, George II passed away at the age of seventy, leaving 22-year-old George III to take the throne. Once he became king, he soon realized it was vital for him to find a suitable wife to bear his sons; the very future of the empire depended on it. Seventeen-year-old Sophia Charlotte of Mecklenburg-Strelitz was the daughter of a duke, privately educated, and had no scandals attached to her name, making her the perfect bride for a king. George and Charlotte did not even meet until their wedding day in 1761. By all reports, the two of them had a mutually respectful marriage; there was no infidelity on either of their parts, and they had fifteen children together. Charlotte and George were avid patrons of the arts, and were especially interested in German music and composers like Handel, Bach, and Mozart. During the first few years of Georges reign, the British Empire was financially shaky, due in part to the aftershocks of the Seven Years War (1756 to 1763). The British colonies were generating little revenue, so strict tax laws and regulations were enacted to bring extra money to the crown coffers. DEA / G. NIMATALLAH / Getty Images Revolution in the Colonies After decades of no representation in Parliament, and resentful of the extra tax burdens, the colonies in North America rebelled. Americas founding fathers famously detailed the transgressions perpetrated against them by the King in the Declaration of Independence: The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States.   After a series of setbacks in North America, Georges advisor Lord North, then the Prime Minister, suggested the king take a break from trying to handle the dissent in the colonies. North proposed that Lord Chatham, William Pitt the Elder, step in and take power of oversight. George refused the idea, and North resigned following General Cornwallis defeat at Yorktown. Eventually, George accepted that his armies had been defeated by the colonists, and authorized peace negotiations. Bettmann Archive / Getty Images Mental Illness and the Regency Wealth and status could not protect the king from suffering extreme bouts of mental illness- some so severe that he was incapacitated and unable to make decisions for his realm. George’s mental health issues were well-documented by his equerry, Robert Fulke Greville, and Buckingham Palace. In fact, he was heavily monitored by staff at all times, even while he slept. In 2018, the records were made public for the first time. In 1788, Dr Francis Willis wrote: â€Å"H.M became so ungovernable that recourse was had to the strait waistcoat: His legs were tied, he was secured down across his Breast, in this melancholy situation he was, when I came to make my morning Enquiries.† Scientists and historians have debated for over two centuries about the cause of the famous â€Å"madness.† One 1960s study indicated a link to the hereditary blood disorder porphyria. People suffering from porphyria experience acute anxiety, confusion, and paranoia. However, a 2010 study published in the Journal of Psychiatry concluded that George probably didn’t have porphyria at all. Led by Peter Garrard, professor of neurology at St. George’s University of London, researchers did a linguistic study of George’s correspondences, and determined that he suffered from â€Å"acute mania.† Many of the characteristics of George’s letters during his periods of illness are also seen in the writings and speech of patients today who are in the midst of the manic phase of illnesses like bipolar disorder. Typical symptoms of a manic state are compatible with contemporary accounts of George’s behavior. It is believed that Georges first bout of mental illness surfaced around 1765. He spoke endlessly, often for hours, and sometimes without an audience, causing himself to foam at the mouth and lose his voice. He rarely slept. He shouted unintelligibly at advisors who spoke to him, and wrote lengthy letters to anyone and everyone, with some sentences being hundreds of words long. With the king unable to function effectively, his mother Augusta and  Prime Minister Lord Bute  somehow managed to keep Queen Charlotte unaware of what was happening. In addition, they conspired to keep her ignorant of the Regency Bill, which decreed that in the event of George’s full incapacity, Charlotte herself would then be appointed Regent. Some twenty years later, after the Revolution had ended, George had a relapse. Charlotte was, by now, aware of the existence of the Regency Bill; however, her son, the Prince of Wales, had designs of his own on the Regency. When George recovered in 1789, Charlotte held a ball in honor of the Kings return to health- and deliberately failed to invite her son. However, the two of them formally reconciled in 1791. Although he remained popular with his subjects, George eventually descended into permanent madness, and in 1804, Charlotte moved into separate quarters. George was declared insane in 1811, and agreed to be placed under Charlottes guardianship, which remained in place until Charlottes death in 1818. At the same time, he consented to his empire being placed in the hands of his son, the Prince of Wales, as Prince Regent. Grafissimo / Getty Images Death and Legacy For the last nine years of his life, George lived in seclusion at Windsor Castle. He eventually developed dementia, and didnt seem to understand that he was the king, or that his wife had died. On January 29, 1820, he died, and was buried a month later at Windsor. His son George IV, the Prince Regent, succeeded to the throne, where he reigned for ten years until his own death. In 1837, Georges granddaughter Victoria became Queen. Although the issues addressed in the Declaration of Independence paint George as a tyrant, twentieth-century scholars take a more sympathetic approach, viewing him as a victim of both the changing political landscape and his own mental illness.

China as a super power Term Paper Example | Topics and Well Written Essays - 1500 words

China as a super power - Term Paper Example On March 4, 2007, China announced that it was going to increase its military to a total of 45 billion dollars (Tkacik, 2007). This was the biggest annual increase in China’s military budget; however, China was quick to reassure the world that there was no need to worry by calling the increment normal. A further look into this increment indicated that China has an intention to challenge the United States’ military supremacy. This could lead to a situation where China is the United States’ single competitor with regard to influence and military supremacy. China’s air force and space activity is on the rise. The army in China has got roughly 300 Russian fourth generation flankers; it has also got several homemade Jian-11 planes and 76 Sukhoi multi-role fighter jets. Russia and Israel assisted the Chinese air force in procuring 50 Jian-10 fighter jets. These jets were based on the United States F-16 technology. China has intentions to build more of these plane s. China has increased its production and deployment of the short-range ballistic missiles which are said to be aimed at Taiwan. This production has grown from 50 per year in 1990s to 150 missiles annually today. The industries that produce such missiles in China are said to grow at the same pace. In general, China’s rocket soldiers and its air force are expanding at an unprecedented pace. According to China’s 2006 White Paper, there is evidence that China is moving to offensive. This military might of China is growing from regional to trans-regional mobility. The air to ground military capacity has also grown, including long distance maneuvers and exceptional operations. The Chinese navy has grown in strength into a force that can operate in the maritime operations and can ably handle nuclear counterattacks. The Chinese air force has continued to increase its capabilities to strike, tried to procure air and missile defense shield systems and is looking into more offen sive and defensive operations. All these are an early warning shot of the Chinese reconnaissance. According to a report by Congress, China’s policy is now global and extremely bold. China has always been underrated and many times the United States said that China has not acquired the status of a super power. Thomas Jefferson, at the beginning of the nineteenth century, observed that the United States had to trade all over the world if it had to become a global power economically. Beijing’s assessment is that it has grown to the extent that its economic growth depends on foreign markets. This also includes the natural resources from other countries around the world. China‘s economy has been growing rapidly, and China is seeking military might that can protect this growth. This is similar to Jefferson’s observation that the United Stated had to build its military strength if it was to safeguard its military strength globally. It seems that the rise of the Pe ople’s Republic of China is both legitimate and inevitable (McLean, 2007). However, according to Condoleezza Rice, the former Secretary of State of the United States, the US needs to help China operate within the international rules framework before it has fully acquires the status of a military super power. Many view the rise of China as an exceedingly dangerous happening. Why does Bleicher think the fears are overblown? According to Samuel Bleicher, the idea that China is an emerging super power is a creation of the media. He believes s that

International Money and Finance (Final stage 3) - Essay Example The company’s annual report 2010 provides clues on the exchange rate risks. Operating Statistics Number of rental stores Staff numbers 31 October 30 April 31 October 30 April 2010 2009 2010 2010 2009 2010 Sunbelt Rentals 346 397 393 5,373 5,733 5,334 A-Plant 104 111 105 1,876 1,944 1,872 Corporate office - - - 11 12 12 Group 450 508 498 7,260 7,689 7,218 The operating statistics on the number of rental stores and staff strength provide a comparative view of the performance of the Ashtead Group in the years 2009 and 2010 respectively in Sunbelt Rentals and A-Plant (Ashtead Group Press Release, 2011). Exchange Rate Risk Ashtead Group is exposed to exchange rate risk developed from translation risk emerging from most of the company assets, liabilities, income and costs written in the US dollars. The changes in the comparative value of Pound Sterling and the US dollar can impact on the financial strength and functioning of the company. All debt of the company is shown in the US do llars to secure to a certain extent the revenue stream, hedging against the translation effects erupting from the shift in the dollar exchange rate. The company pays dollar interest on its debts to reduce the impact of any shift in the dollar exchange rate on its income (Ashtead Group Annual Report Accounts, 2010). Movements in the rate of the US dollar with respect to Pound Sterling has been having and crucial impact on our financial position and outcomes of operations as registered in pounds are because most of the company assets, liabilities, income and costs are represented in US dollars. Movement in the exposure of the firm against Pound Sterling or other currencies however, can create significant transaction exposure for the firm. Higher level of exposure can affect the firm’s short term cash flows and therefore may force the firm to borrow to meet its short term cash requirements. (Moffett, Stonehill, & Eiteman,2009). Till 31 October 2010 all company debts shown in the US dollar were nearly 80% of the value of net assets shown in dollar. It proved out to be robust hedge against currency fluctuations. It reduces the impact of exchange rate fluctuations as interest is paid through dollar as well, thus, reducing the effect on pre-tax profits and income. Based on the latest currency mix of Ashtead Group’s profits and on dollar debt levels, interest and exchange rates at 31 October 2010, a 1% change in the US dollar exchange rate would impact pre-tax profit by ?40,000 (Ashtead Group Press Release, 2011). The company has been benefitting from the strong dollar in the past, as is evident from the results of Sunbelt from stronger dollar in the year 2009 when revenues in dollar were short by 21% across the year to US$1450 million but in reality increased by 7% when shown in UK sterling (International Rental News, 2009). Ashtead's Sunbelt results were boosted by the stronger dollar. Sunbelt's revenues in dollars fell by 21% over the year to US$1450 million, although actually grew by 7% when expressed in UK sterling. A-Plant's sales for the year fell by 2% to 208.0 [pounds sterling] million. Dollar exchange rate hedging worked well for the company in the year 2009 amidst reducing sales for both the companies of the group in the final quarter with 28% cut in income by A-Plant and 24% reduction in the income of Senbelt in local

Compulsive Gambling Essay Example for Free

Compulsive Gambling Essay More than 5 million Americans are pathological, compulsive and problem gamblers, and another 15 million are at risk of becoming just like them. A common definition of problem gambling is: a progressive disorder characterized by a continuous or periodic loss of control over gambling and irrational thinking and behavior despite the consequences. When gambling interferes with any ones life, it can be categorize as an addiction or disease, just like alcohol and drug addiction is categorize as a disease. A study conducted for the National Gambling Impact Study Commission found that 20 million American have or could develop gambling problems. Also they have estimated those 1. 8 million American adults as well as up to 1. 1 million American adolescents age 12 through 17 engage in severe pathological gambling each year. As legalize gambling has become more common in the United States; problems have sprung up as well. That negative influence is becoming more apparent as gambling is more widely available. It is becoming increasingly easy to gamble in the United States particularly in the last 10 years, and problems with gambling are much more common now than they ever were. Studies show that for every dollar gambling produces for a regional economy, three dollars are lost because of the economic and social cost of gambling. The study has also said that if the government legalizes more gambling, taxpayers will lose money, whether they gamble or not. The gambling industry believes it is just selling an innocent form of family entertainment, but they dont mention how much the players lose or how gambling encourages addictive behavior or the enormous costs it creates for the rest of society. It has been said that, gamblers with higher counts of gambling symptoms will have higher rates of problem. There many consequences associated with compulsive, pathological and problem gamblers. Examples of such consequences include job and financial problems, divorce, poor health, and criminal involvement. These addictions are the lifeblood of the gambling industry, said an economist from the University of Illinois by name Earl Grinols. He researches and found out, that casinos earn more than half their revenues from compulsive, pathological, and problem gamblers. The casino industry is heavily dependent on the revenues of psychologically sick people, says Grinols. Millions of families are paying a heavy price, not just financially, but also strains in family and marital relationship. Family members of compulsive and pathological gamblers are hurt by their disease, mainly because an emotional withdrawal occurs, which leads to separation.

Free Essays on What Factors Caused The Collapse Of Palatial Mycenaean Civilization

What factors caused the collapse of palatial Mycenaean civilization and what theories support this collapse? The Mycenaeans were a warlike people - warriors who set out from their fortified cities of Southern mainland Greece for the Mediterranean Sea, looking for metals such as copper, tin and gold. Establishing their society around 1700 BC, the Mycenaeans came to power at 1600 BC and ruled to 1100 BC, with the city of Mycenae as the focal point of their civilization. Flourishing for roughly five hundred years, the collapse of Mycenaean society occurred at approximately 1100 BC. Though there are various theories offered for the collapse, actual suppositions remain to be completely authenticated. Theorists propounding as to what caused the collapse of Mycenaean civilization, present numerous suppositions. Desborough posed one of the theories in 1964. He cautiously suggested that an attack from the north by the Dorians instigated the collapse. While he theorized, Desborough was acutely cognizant of the reality that there was virtually no evidence, with the exception of the destruction levels and widespread abandonments themselves, for the presence of such invaders. A new type of sword, (from Central Europe, named the ‘Naue II’), and an inventive type of pin called a ‘fibula,’ (or safety pin), were both perceived to be Dorian trademarks by archaeologists. Unfortunately, there is a principal protestation to this theory - only half a dozen of these goods were found for the fifty years that the Dorians were supposed to have rampaged. Furthermore, neither item appeared at the same time as the other, so they could not be related to a single invasion, a further objection to Desborough’s theory. A decade earlier, in 1954, Andronikos posed a supposition that deals with a wholly different matter than Desborough’s theory. Andronikos proposed that the collapse came about as the result of extreme social unrest, with...

These Are the Hardest AP Classes and Tests for You

These Are the Hardest AP Classes and Tests for You SAT / ACT Prep Online Guides and Tips Thinking of signing up for AP classes? Want the greatest possible challenge? Or are you trying to avoid biting off more than you can chew? In this post, we’ll explain what makes an AP class hard, list the hardest AP classes, and help you prepare for them. What AP Passing Rates Tell Us You might think that the best way to tell which AP classes are the hardest is to look at the national data about how many students pass each test each year. We’ll start our discussion here, but beware that the passing rates don’t automatically tell you which classes are hardest. Want to get a perfect 5 on your AP exam and an A in class? We can help. PrepScholar Tutors is the world's best tutoring service. We combine world-class expert tutors with our proprietary teaching techniques. Our students have gotten A's on thousands of classes, perfect 5's on AP tests, and ludicrously high SAT Subject Test scores. Whether you need help with science, math, English, social science, or more, we've got you covered. Get better grades today with PrepScholar Tutors. This a complete list of passing rates on each AP exam with the most recent (2019) data. Exam Name Passing Rate (3+) Studio Art: Drawing 91.1% Spanish Language and Culture 89% Chinese Language and Culture 88.3% Studio Art: 2-D Design 86.4% Calculus BC 81.5% Physics C: Electricity Magnetism 81.1% Seminar 80.7% French Language and Culture 76.7% Research 76.2% Japanese Language and Culture 75% Computer Science Principles 72.7% Spanish Literature 71.9% Physics C: Mechanics 71.1% German Language and Culture 70.5% Studio Art: 3-D Design 70.1% Computer Science A 69.9% Microeconomics 68.4% Gov. and Politics - Comparative 66.2% Biology 64.6% Italian Language and Culture 64.6% Psychology 64.4% Art History 63.9% Physics 2 63.5% Music Theory 63.4% Latin 63.1% Statistics 59.2% European History 58.4% Calculus AB 58.3% Macroeconomics 57.9% World History 56% Gov. and Politics - United States 55.2% English Language and Composition 55.1% Chemistry 54.6% United States History 54.3% English Literature and Composition 50.1% Environmental Science 49.6% Human Geography 49.1% Physics 1 44.6% Source: College Board. For language rates, "Total" includes all students, while "Standard" includes only those students who didn't indicate they speak this language at home or spent more than four weeks studying it abroad. You might be tempted to look at this table and say the tests with the lowest passing rates are hardest, and the ones with the highest passing rates are easiest. After all, if not many students can pass an AP test, doesn’t that mean it’s one of the hardest tests? But when you look at the data, the exams with the highest passing rates (Chinese, Spanish, Calculus BC) are often considered among the hardest. We're not including AP Seminar and the AP Studio Art scores in this assessment, since those grades are all portfolio-based, rather than exam-based. Meanwhile, some of the tests with the lowest passing rates (Human Geography, US Government and Politics, Environmental Science) are often seen as the easiest. So what’s going on here? The truth is, the national passing rates often say more about the students taking the exams rather than the exams themselves. Some of the exams with low passing rates have those low rates because they are often taken in freshman/sophomore year, while some of the exams with high rates have more stringent prerequisites at many high schools. This means that the harder exams tend to have older, better-prepared students taking them, which raises their pass rates. In short, we have to look beyond national passing rates when figuring out which tests are the hardest. A Possibly More Reliable Indicator: 5 Rate Since pass rates don’t actually tell us much, what about the 5 rate? Remember, a 5 is the highest possible AP score (read more about AP scores here). Shouldn’t we be able to find the hardest AP tests by looking at the exams with the lowest 5 rates? Below is a table with all the AP exams, this time ranked by the percentage of test-takers who got a 5. Exam Name 5 Rate Chinese Language and Culture 57.2% Calculus BC 43.2% Japanese Language and Culture 38.2% Physics C: Electricity Magnetism 35.9% Physics C: Mechanics 34.6% Computer Science A 27% Spanish Language and Culture 24.9% Microeconomics 22.2% Gov. and Politics - Comparative 22.2% Studio Art: 2-D Design 21% Music Theory 20.9% Studio Art: Drawing 20.8% Psychology 20.2% Calculus AB 18.9% German Language and Culture 18.4% Macroeconomics 17.6% French Language and Culture 15.5% Statistics 14.5% Computer Science Principles 13.6% Latin 13.1% Gov. and Politics - United States 12.9% Physics 2 12.6% United States History 12.1% Art History 12% Italian Language and Culture 11.8% European History 11.7% Research 10.8% Chemistry 10.7% Human Geography 10.7% English Language and Composition 10.1% Studio Art: 3-D Design 10.1% Environmental Science 9.5% Spanish Literature 9.1% World History 8.7% Biology 7.1% Seminar 6.8% English Literature and Composition 6.2% Physics 1 6.2% Source: College Board. For language rates, "Total" includes all students, while "Standard" includes only those students who didn't indicate they speak this language at home or spent more than four weeks studying it abroad. The 5 rate, in fact, a decent way to spot some difficult exams, including AP English Literature and Biology. They both have very low 5 rates (7.1 for Bio, 6.2 for English Lit). But on the flip side, a relatively easy exam, AP Environmental Science, has a low 5 rate of 9.5%. Furthermore, some decidedly hard exams, like Chinese, Calculus BC, and Physics C, have very high 5 rates- up to 57%+ for Chinese! In other words, just looking at 5 rates doesn’t tell the whole story, though some other articles have assumed that. This is why the best way to find the hardest AP exams is to focus on the ones with the most material to cover- as well as the most conceptually difficult topics, which we will do below. Disclaimer: Take Into Account Your School’s Variation Before we talk about which classes are the hardest, we want to clarify we mean the ones with the most difficult course material and hardest end-of-year exam. There is enormous variation in how the same AP class can be taught at different high schools, so we can't speak to the specific class difficulties at your high school. It may be there is an AP class at your school that is known as the most difficult since the teacher is really tough, even though nationally it might not be considered one of the easiest. Or maybe there is an AP class at your school most students see as a joke, even though the material is still very difficult. Since we can’t report on the specifics at different high schools, we are focusing on which classes have the most/hardest material to cover and have a reputation for difficulty at multiple schools. We’ll discuss below ways to explore how hard AP classes are at your school specifically so you can build an optimal schedule. Any AP class Professor McGonagall teaches would likely be super hard. Okay, Seriously, Which AP Classes Are the Hardest? United States History, Biology, English Literature, Calculus BC, Physics C, and Chemistry are often named as the hardest AP classes and tests. These classes have large curriculums, tough tests, and conceptually difficult material. We put together this list based on personal experience, online chatter, passing rates, 5 rates, and looking at their curricula in depth. We are not ranking these since their difficulty will vary quite a bit based on the student. For example, if you're a math whiz, Calculus BC will likely be easier than AP English Literature. But the opposite could be true for another student. But if you’re considering any of these, be prepared for a tough course! AP US History Even though most students are exposed to American History multiple times, beginning in elementary school, AP US History is still a very tough class. First of all, this is a harder history exam than AP World History or even AP European History, since it covers a narrower span of history and a smaller geographical area, meaning the curriculum is incredibly detailed. This means you can’t rely on general trends and observations like you can sometimes in World History- you have to know specific dates, movements, people, and laws. To take a small example, in a world history class, you might need to know that slavery ended in the United States during the Civil War. For a US history class, you would need to know the dates of the civil war, the exact year of the Emancipation Proclamation, and the dates and content of the 13th, 14th, and 15th amendments. You would also be expected to know about the major leaders and law-makers involved. The more detail you can remember, the better! This is because APUSH is known for having a very difficult multiple-choice section that requires a very detailed knowledge of US History from the pre-Columbian era up to the present day. Also, the more concrete evidence you can include in your free responses, the better essay scores you will get. If you have a knack for history, this class will be easier for you, but most students report it’s very challenging. It’s also likely to be a hard class to pass at many schools because teachers have to assign tons of reading and assignments to get through all the material before the AP test in May. Expect a fast-moving, assignment-heavy course. You can read College Board's full description here. If you think this is a figure from American History, you might want to consider fitting AP US History into your schedule. AP Biology This is a tough class and test, any way you slice it. Even with the redesign back in 2012, which was meant to make AP Biology more accessible and less memorization-heavy, you still have to memorize tons of material for the test, everything from super detailed chemical processes (Krebs Cycle, anyone?) to cell biology to evolution. This means AP Biology teachers have to pack a ton onto their syllabi for this class, including time for experiments. The huge volume of info, coupled with the fact that Biology can be conceptually difficult, makes this a tough AP course. If you have taken a strong prerequisite Intro to Biology course, this test will be more manageable. Check out a full course description here to learn more. AP English Literature Along with AP US History, this is one of the hardest AP courses in the humanities. While AP English Language is also challenging, Literature requires reading texts that are generally more difficult. Compare, say, AP English Literature staple Crime and Punishment to a non-fiction article about the criminal justice system you might read in AP English Language. Crime and Punishment is much more difficult! AP English Literature also tests more specific rhetorical/literary terms and requires you to have a more fine-tuned ability to close read a passage. You’re not just looking for the overall argument or effect like you are in AP English Language. You have to go under the hood and explain in detail how a piece of literature works. Finally, for AP Literature, you have to come prepared to write one of the essays about a book or play you read in class, but you can't actually bring the book or play with you to the exam. This means you have to study what you read in AP Literature very closely. So closely that you could write about a book, and even use quotes from it, without having the book with you! SparkNotes summaries won't cut it. In short, expect a longer and harder reading list, tougher multiple-choice questions, and more accountability for what you read in class. You can read the full College Board description of the test here. AP Chemistry Similar to biology, chemistry has a ton of material, lots of memorization, and requires a solid conceptual understanding of complicated chemical processes. AP Chemistry is known at many high schools for having tons of homework and tough tests- all necessary for students to learn enough to pass the AP exam at the end of the year. Don't attempt AP Chemistry unless you have already taken an introductory chemistry course. It would be impossible to learn everything you need to know about chemistry for the AP exam in just one year. You can read AP’s full course description here. AP Physics C Physics C is especially tough because not only are you learning physics material, which can be hard, you also need to know calculus alongside it. While AP Physics 1 and 2 are algebra-based, both Physics C courses (Electricity Magnetism and Mechanics) are calculus-based, meaning students need to know calculus well enough to apply it in physics. Some consider it â€Å"two classes in one† due to the necessary calculus knowledge. Furthermore, the material tested in Physics C is much more in-depth than Physics 1 or 2 (or the old Physics B). Physics C courses go into a great amount of depth about a few topics, while Physics 1 and 2 cover many topics with less depth. So just as US History is harder than World History, Physics C is tougher than Physics 1 and 2 because you need a greater depth of knowledge. Because of this, you should definitely have a physics prerequisite under your belt before taking Physics C, and you should have either already taken calculus or be taking it at the same time. You can read about Physics C at the course home pages for Electricity and Magnetism and Mechanics. AP Calculus BC Finally, AP Calculus BC is the toughest AP math exam, if not one of the hardest AP exams period. AP Calculus AB is also challenging, but covers less material and moves more slowly. AP Calculus BC often covers everything taught in Calculus AB in just the first semester of school- revealing one reason why it’s so hard: intense pacing. You move fast in Calculus BC, which means you need to be prepared to keep up. There is not a lot of time to be lost in this class. If you struggle with a concept at the beginning of the year, it can make it harder to learn everything after that. In fact, if you find yourself struggling, seek out extra help from the teacher or a tutor as fast as you can so you don't fall behind. In some schools, Calculus BC requires an extra period in the day to fit in all the material before the AP exam. You also get into more conceptually difficult calculus topics than Calculus AB. In short, be prepared to work very hard and be vigilant about keeping up with the course. You can read College Board’s description here. Want to get a perfect 5 on your AP exam and an A in class?

Note on Language AP Exams You may be wondering how hard the AP language tests are- after all, you can take AP tests in languages from Chinese to Spanish to French. The difficulty of these is a bit tougher to quantify, since AP Language exams test multiple years of learning a language, as opposed to one year of material. For students with tons of foreign language knowledge these can be incredibly easy exams. If you’ve lived abroad or are fluent in a language, the AP language test will not pose much of a challenge. (Some students who are native speakers of a language will even take an AP language exam!) But for students who have just been taking a language in school, these exams can be difficult, particularly the listening portions. So if you’re thinking about an AP Language class, think about how many years of past experience you have. For example, if you’ve taken French for four years, you’re probably well-prepared for AP French. But if you’ve only taken it for two years, you will probably struggle. Most schools have pretty stringent prerequisites for AP language classes for this reason. Action Steps If you want to take any of these classes, you need to get info about the class at your school. Although they are all objectively difficult, there can be huge differences in how the classes are taught and graded. Ideally, these classes should be taught by excellent teachers who can not just teach the material clearly, but include plenty of review and AP exam practice. You should also think about your own strengths and weaknesses, and how well a tough AP class will fit into your schedule. Even though all of these AP classes have tough material, the difficulty of the class might vary from school to school. The class itself could be incredibly difficult (lots of assignments, reading, and hard tests)- and you should be prepared for that. However, the class could also be easy (not very many assignments, easy tests), meaning you will have to put in a lot of work on your own to be ready for the AP test. Knowing what the class’s workload is like, and how that prepares you for the exam, is crucial to being prepared once May arrives. If the class is easy and you don't actually learn the material, you could fail the test despite getting good grades in the class. The bottom line here is that you’ll have to work very hard to succeed in any of these classes. But that work could come at the behest of a teacher or from your own willpower. If you don't think you're learning the material well enough in class to pass the test, consider getting a prep book and studying on your own in the second half of the year. Get Info About a Class To get info about an AP class, first talk to your guidance counselor. Ask for the class's syllabus, the class’s passing rate on the AP exam for the last few years, and what other students tend to say about the class. This will give you an idea of how well-taught a class is. Your guidance counselor can also recommend good prerequisite classes and teachers. Next, speak to the teacher if you can, or speak to a teacher you have who teaches the prerequisite class (for example, the Honors Biology teacher if you’re thinking about AP Biology). The teacher can give you a sense of what the workload is like, what they expect of their students, and how much work they expect students to do on their own. Finally, find out what the word of mouth for the class is at your school by talking to older students. Don't rely too much on any one person's opinion, because students can exaggerate, but look for general trends. For example, if everyone says that AP Biology is really hard but they learned a lot and passed the AP exam, that's a sign the class is worth taking. Think About Your Strengths If you tend to do well in a subject, you will likely do well in a corresponding AP class, even if it's one of the hard ones. For example, even though AP Biology is hard, if you’ve done well in previous science classes, have a knack for memorization and critical thinking, you might be better prepared for AP Biology than, say, AP European History, even though that’s not seen as one of the hardest AP classes. On the flipside, if you really struggle with something- like writing or math- you need to be extra careful about taking a tough AP class like AP English Literature or AP Calculus BC. We’re not saying to avoid those classes if you think you might have a hard time. We are saying to be prepared to spend lots of time studying! Think About Your Overall Schedule How well you do in a hard AP class could also depend on your schedule. For example, AP Biology might be more feasible your sophomore or senior year since you won’t be worrying about the ACT/SAT. However, if you take it junior year, you might have a hard time balancing ACT or SAT studying with the AP Biology class. Also consider other classes, your extracurricular commitments, work schedule, and family commitments before signing up for any of these AP classes. You don't want a tough AP class to overload an already busy schedule. Along the same lines, do not feel pressured to overload on AP classes in general. More is not necessarily better, even if there is pressure at your school to take 5 AP classes in one year. It’s better to get two 4s than four 2s! And it's better to take AP classes that are interesting and meaningful to you. What’s Next? Find out about the flipside of this discussion, the easiest AP classes.

Critical Review about Postgraduate Research Methods Essay

Critical Review about Postgraduate Research Methods - Essay Example The author defined the glass ceiling as those artificial barriers based on attitudinal or organizational bias that prevent qualified individuals from advancing upward in their organization into management-level positions. Since the feminist movement gained power since the late sixties of the twentieth century the women began to think that they should gain the power and authority among the men community. As a result they from the very beginning women placed themselves to the other side of the discussion. Nowadays women are trying to prove their self-dependence, putting aside the case of that they had begun this confrontation. To show the relevance of the problem, the author shows some statistic data about salary inequities between women and men. She asks following questions: Why are women still paid substantially less than men are Why does the glass ceiling stay in place And why does much of the popular press do its best to paint a rosy picture of job prospects for women The main purpose of Brenda's research was to identify factors that support and perpetuate the glass ceiling for women in public relations and corporate communications management. The author points out, that many researchers in management have attempted to isolate factors contributing to sex segregation and sex discrimination. After analysis of their work she made a conclusion that the body of knowledge is contributed in two very important ways: First, it highlights the need for research about women, research frequently marginalized in both the academic and business arenas. Second, it has begun to suggest factors that create and maintain the glass ceiling in corporate public relations and communications. The author describes in details research problem and its reflection in literature. The research project assumes the glass ceiling as an important area for further study for several reasons that are enumerated by the author. Feminization of the field means that although women make up more than half of the U.S. population their representation in management in public relations and many other fields is a much smaller percentage. The author points out that this limits opportunities for women and the organizations that could benefit from their contributions. Vrenda emphasizes that women in public relations have difficulty being treated equally in terms of advancement and salary. She looks at nature of today's business climate and remarks that the pressure on organizations to practice public relations as more of a two-way communication process becomes even more urgent. The author suggests the following points for consideration: 1: Do women in corporate public relations and communications management perceive a glass ceiling to be in place 2: What factors do women think help to create or maintain the glass ceiling for women in public relations and communications 3: What strategies are there for women in public relations and communications who want to work to eliminate the glass ceiling These are the main questions of the research. In the research the author used qualitative methods because, as the author explained it, the factors contributing to the glass ceiling have not yet been clearly delineated. The study used focus groups (one pretest and two subsequent focus groups) and depth interviews (a total of 10 interviews). Nevertheless, the author uses statistic to show the tendency of nowadays situation in case that groups are too small to show off the full idea. That is reasonable because
