High Cost of Poverty in the United States Essay

Destitution can be characterized from multiple points of view. In specific endeavors, it very well may be utilized in numbers, while different definitions can be increasingly unclear, and used to characterize a way of life. The characterized term of neediness is â€Å"the condition of one who does not have a standard or socially satisfactory measure of cash or material possessions†. (Mirriam Webster, 2011) According to the U.S. Enumeration Bureau, in excess of 37 million individuals live underneath the destitution line. â€Å"The positions of America’s poor expand to very nearly 1 of every 6 individuals a year ago, arriving at another high as long haul joblessness left a large number of Americans battling and unemployed. The quantity of uninsured edged up to 49.9 million, the greatest in more than two decades.† (Yen, 2011) Poverty is clearly basic in our nation, and everywhere throughout the world. Indeed, even with the United States being the wealthiest nation o n the planet, we despite everything have numerous Americans who battle ordinarily to endure. The theme I decided to concentrate on is the significant expense of destitution, and how it really costs more to be poor. In spite of the fact that it appears to be an interesting expression, it is a practical point. I picked this subject since I have actually been associated with the two sides of financial statuses. Despite the fact that I don't live in outrageous destitution, I actually have a salary that falls inside the line of neediness, yet I don't have a family to help and have understudy advances to live off of. I needed to know further detail of how the individuals who just experience neediness, have restricted options, and how their impediments really cost them more cash. My own background is one from an upper working class family, and was brought up in a well off suburb in a predominately white network. My family never had money related battles, so I had no involvement in doing combating bills. I worked in secondary school and had my own cash, however I had nothing to pay for. I thought I made a not too bad measure of cash making $7 60 minutes, and just working 15-20 hours per week. For an individual without any bills or leases to pay for, $150-200 seven days was a ton to me. As of late, I moved out of my parent’s rural home and into the city to be nearer to class and increase some autonomy as a grown-up. I make about $250-400 per week, contingent upon the action of the eatery I server at. I before long understood that I am exceptionally reliant on my two flat mates to part bills and lease, since I would never bear to live all alone. In spite of the fact that we live in a low salary neighborhood, the expense of food, lease, electric, warmth and link charges stack up, and I battle to pay them. I additionally just compensation 33% of the full expense. I have a vehicle I have to place gas in, an exercise center participation I pay month to month and Visa charges each month. I presently perceive how individuals that make the same amount of, or short of what I do, battle much more to make a decent living when their salary is at the leader of the family. I needed to demonstrate to individuals that it is increasingly costly to be poor, due to the absence of assets, salary and credit, and furthermore what their choices become for endurance because of these conditions. I additionally did a quantitative report on leasing as opposed to possessing a thing, to show that it really costs more to lease something than to buy it forthright. I decided to test a similar three things from two unique stores, and recording the costs to see the distinctions of leasing and claiming it. I am mindful that most people in destitution, as a rule need more cash to buy things or homes forthright so they frequently lease them, figuring they can bear the cost of week after week or regularly scheduled installments to loosen up their pay to manage the cost of other life necessities. My first idea I decided to center was access to food. I pondered the amount I spend on the food I appreciate for only for me by and by, and I think it is costly. I appreciate products of the soil vegetables, brand name grains and costly breads. Since I grew up eating the specific brands, I proceed to attempt to bear the cost of the things I like. Being a person with a low salary, I can't envision supporting myself, however a family exclusively on my pay. In this exploration paper, I will clarify the hardships of getting to and from the supermarket, and on the off chance that you can't, you have to shop somewhere else, for example, corner stores.† Prices in urban corner stores are quite often higher, business analysts state. What's more, at times, costs in markets in less fortunate neighborhoods are higher. A considerable lot of these stores charge more on the grounds that the expense of working together in certain areas is higher.† [ (Brown, 2009) ] This can prompt investing additional energy, threat, stress, and at long last, costing the individual more cash. It additionally powers those with less cash to spend, higher hazard for stoutness. â€Å"Inequitable access to solid nourishments is one component by which financial variables impact the eating regimen and strength of a population†. (Drewnowski, 2009) Since they don't have the cash to bear the cost of solid decisions, they should pick nourishments that they can loosen up so as to take care of their families, regardless of whether it isn't sound. My next idea I decided to contemplate was the cost of the lowest pay permitted by law, and how it isn’t actually the base inclusion of standard living. In New York State, the lowest pay permitted by law is $7.25. â€Å"About 20% of American grown-ups who have employments are gaining under $10.65 60 minutes. Indeed, even at 40 hours per week, that adds up to under $22,314, which is the destitution level for a group of four†. [ (Isidore, 2011) ]. This just expresses a month to month pay of about $1,000-$2,000 is practically difficult to get by on. This may prompt awful credit, constrained into leasing, and having individuals do hazardous or crime to get cash or things for their families. The neediness rate for all individuals camouflages considerable variety among racial and ethnic subgroups. Neediness rates for blacks and Hispanics enormously surpass the national normal. As per the United States Census Bureau, â€Å"In 2010, 27.4 percent of blacks and 26.6 percent of Hispanics were poor, contrasted with 9.9 percent of non-Hispanic whites and 12.1 percent of Asians.† (Bureau of the Census, 2011) Poverty rates are regularly the most noteworthy for families headed by single ladies, especially on the off chance that they are dark or Hispanic. â€Å"In 2010, 31.6 percent of family units headed by single ladies were poor, while 15.8 percent of families headed by single men and 6.2 percent of wedded couple families lived in poverty.† (Bureau of the Census, 2011). â€Å"The official destitution level is a yearly salary of $22,314 for a group of four â€Å". (Yen, 2011) By and large, contingent upon the size of a family, a family living in destitution has a normal salary of under $20,000. This can incorporate couples with youngsters, single guardians with at least one kids. Obviously, this isn't a ton of cash to help a family on, and consequently they need to find a way to endure, which brings about greater expenses, and adding to the announcement of the significant expense of neediness. You must be rich to be poor. This is the thing that a few people, who have never lived underneath the neediness line, don’t comprehend. The more unfortunate you are, the more things cost. Extra strides in cash, time, bother, fatigue, and threat. This is an unavoidable truth that TV, magazines and media, don't frequently clarify. Take for instance, food. To start with, in the event that you don't have a vehicle, getting to the general store can take somewhere in the range of one to three hours of open transportation, and costing a cost to utilize the transport or a taxi. To utilize the strategy for open transportation, it is important to need to stack the entirety of your staple goods into the transport, or taxi. This is constraining to space and capacity of conveying the entirety of some staple goods. A more straightforward form of this is stroll to the corner store, for nothing, yet where the basic food item determination is constrained and costs are multiplied. â€Å"Prices in urban corner stores are quite often higher, business analysts state. What's more, some of the time, costs in grocery stores in more unfortunate neighborhoods are higher. A significant number of these stores charge more in light of the fact that the expense of working together in certain areas is higher.† (Brown, 2009) Also, in the event that you are living in neediness, you will probably not be bringing in enough cash to purchase $100 or increasingly worth of food supplies for your family. This outcomes in the individual or family going through more cash, to either get to the supermarket, or paying more for the food to set aside cash heading out to and from. At long last, it is a losing circumstance, and the p oor are paying more at long last than somebody who is affluent and approaches the essential assets. Going through more cash than working class, or well off class to purchase food supplies is one case of how high the expense of neediness is. In the event that the poor is going through cash in the corner stores, they are in all probability not getting nutritious nourishments or sound decisions that most corner stores don't convey. Heftiness is an immediate outcome from that, seeing that undesirable nourishments cost route not exactly smart dieting does.† Obesity and type 2 diabetes follow a financial inclination. Most elevated rates are seen among bunches with the least degrees of instruction and pay and in the most denied zones. Unjust access to solid nourishments is one instrument by which financial components impact the eating regimen and strength of a population†. (Drewnowski, 2009) Low pay levels leave individuals no decision yet to pick nourishments that are supplement poor, since it is a value that can bear the cost of and something they can loosen up among their e ntire family to take care of them. It is likewise the most ideal approach to give day by day calories at a moderate expense. The individuals who are battling monetarily are plainly the most burdened with regards to smart dieting propensities. In our supermarkets today we have such a significant number of counterfeit sugars, additives, fats and desserts that make certain to taste great, however not useful for our wellbeing. Fats and desserts will in general cost way less, where as solid nourishments cost more. It looks bad to have undesirable nourishments cost not exactly solid nourishments, yet it is the assembling and creation that decides the expense of food sources. In this manner, those wh

How students say SIPA lives up to its international reputation COLUMBIA UNIVERSITY - SIPA Admissions Blog

How students say SIPA lives up to its international reputation COLUMBIA UNIVERSITY - SIPA Admissions Blog My name is Hisato Tamiya and I am a first-year MPA student. I am concentrating in International Finance and Economic Policy and specializing in Management. Three months have passed since I started my SIPA life. Before coming to SIPA, I felt uneasy because it was the first time I was leaving Japan to live in a foreign country; nonetheless, thanks to the Admission Committee’s dedicated help, I am really enjoying my SIPA life. In this column, my classmate Yoshihisa Kita and I will give you a snapshot about SIPA life. Huge Diversity: Where the World Connects This year SIPA’s degree programs have an entering class of  around 600 people from all over the world. I am excited to discuss a variety of topics with such diverse students. One of my favorite classes is “Politics of Policymaking” with Prof. Christopher Sabatini. In this class of around twenty people, we discuss a wide range of topics, such as foreign policy proposals for the next president, and policy proposals for India to implement conditional cash transfer. When we discussed how to create effective conditional cash transfer policies in India, our Indian classmates gave us concrete feedback. For instance, I was not knowledgeable about income inequality, living standards, and available statistics in India. These details are essential to make our discussion fruitful, and their advice enabled me to discuss policies as if I were in India as a member of a mission team for its development. In addition, I see these lively discussions between professors and students happening even in a large classes, like “Accounting for International Public Affairs” by Prof. Alan Brott. Moreover, all of my professors (including those who teach larger classes) work to remember all of our names and faces! When I studied and worked in Tokyo, I never experienced such diverse classes and active discussions, let alone have a professor work to get to know his or her students like my SIPA professors do. I can definitely say that SIPA is a place worthy of its catchphrase, “Where the World Connects.” Broad Option of Classes Since my concentration is International Finance and Economic Policy, I am taking these classes this semester: Politics of Policymaking Accounting for International Public Affairs International Finance Monetary Theory Decision Models Management Advanced Techniques in Excel Data Management and Analysis in Excel SIPA offers hundreds of courses each semester to accommodate the more than 1,000 SIPA students across our eight degree programs. In addition to wide range of classes in SIPA, we can also register for classes at the Columbia University Department of Economics, Columbia Law School, and Columbia Business School, for example. Students can also attend special lectures by renowned speakers, such as Ban Ki-moon and Robert Merton Solow. When I attended a special lecture by Ban Ki-moon, he lively illustrated his duties in his current job, which gave us concrete images to what it is like to work in intergovernmental organizations. Not only that, I was very impressed his words: “we, who implement public policies, always have to keep both passion and compassion. These great opportunities motivate us to work for public.” For me, it would be impossible to easily obtain these opportunities if I were in Tokyo. SIPA Community: Connect with Seeples In order to discuss public policy, we need friends to have heart-to-heart talks. I believe that SIPA is one of the best places to make magnificent friends and counterparts from around  the world. To connect with one another, the SIPA community has more than 40 clubs. I joined the Japan Study Student Association (JASSA), which shares with the SIPA  community the beauty of Japanese culture. We even help prospective students learn more about JASSA and SIPA by listing information on the JASSA website. (Recently, I posted about SIPA’s curriculum.) In the next half of this blog post JASSA , President Yoshihisa Kita will tell you more about JASSA as one aspect of SIPA life. JASSA Hi! Thank you, Hisato, for introducing me. I’m excited to share my experience in SIPA as a president of JASSA. There are several country/region specializing student bodies in SIPA. Among them, JASSA is focusing on Japanese culture, policy, and economy. This year, JASSA hosted a bunch of students-led events: a Japanese sake tasting, a roundtable on the mega-hit movie “Shin-Godzilla,” and a Japanese art workshop. JASSA doesn’t only offer cultural events, as we invite a lot of policy experts from outside the Columbia community to participate in the program, such as high-level governmental officials from the Ministry of Finance/Bank of Japan, or executives from Japan Railway. We are pleased to offer opportunities for students to hear directly  from those who work in the policy field in Japan. Last but not least, JASSA organizes our annual Japan Trip during spring break. This year, Japan Trip celebrated its 10th anniversary, bringing 45 students from 17 different countries to Japan. We traveled tirelessly through Kyoto to Tokyo as a one-week trip. We woke up at 4 am. to visit Tsukizi fish market, while staying up until midnight singing in karaoke. The trip impressed the participants so much that some of them totally changed their view toward Japan! I think JASSA’s activities represent one of the high points in SIPA life. Students with diversified backgrounds contribute to SIPA community in various ways. It also provides me with opportunities to look back at my home country with different points of view. I am ready to welcome you as a Seeple to share cultures. See you at SIPA, where the world connects.

Criminal Profiling Real Science of Just Wishful Thinking...

Criminal profiling is an investigative technique used by many law enforcement agencies notably the Federal Bureau of Investigation (FBI) in the analysis of elusive criminals through studying their criminal profiles. Profiling is usually done on basis of the type and nature of crime. Usually studies are conducted as to the offenders whereabouts and occupation before, during and after a particular crime was committed. After this, evidence is then combined against the different types of personalities and a fitting description of the criminal is able to be formulated. However, it is important to note that in any criminal profiling attempt, the criminal psychological mind must be described fully by their actions during and after the crime. For†¦show more content†¦If asked the same question, I would perhaps reply by insinuating that while it may actually be luck profiling really helps in the narrowing down of the list of possible offenders and thus in my opinion it is quite effec tive. The purpose of this paper is thus to analyze in detail, whether or not criminal profiling is beneficial or is it just real science of wishful thinking? How effective is Criminal Profiling in the Solving of Crimes? Many critics of criminal profiling presume that criminal profiles are usually too big to create the desired picture and that it takes a little more than common sense to successfully profile a criminal. If we are to acknowledge that profiling is a science, then it is only so because psychology as a science comes into focus in the solving of crimes. It is and has been proven possible, that the psychological study of people helps in the determination of their behavioral dispositions accurately. Going from this statement, it is thus of importance to realize the fact that criminal profiling is a major asset to many law enforcement agencies as some crimes are just not ordinary, and require specific studies into their nature for a proper profile to be acquired.

Oxidative Stress and Diabetic Nephropathy Free Essays

Introduction Diabetes mellitus is a chronic non-communicable condition resulting in high levels of glucose in the blood. It occurs due to inability of the beta cells in pancreas islet tissue to produce enough insulin, or when the body becomes resistant to insulin. It reduces both quality and length of life and over time leads to serious complications such as coronary heart disease, stroke, neuropathy, retinopathy and nephropathy. We will write a custom essay sample on Oxidative Stress and Diabetic Nephropathy or any similar topic only for you Order Now There are two main types of diabetes mellitus: Type 1 diabetes: also called insulin-dependent diabetes mellitus (IDDM), early-onset and juvenile diabetes. It is an autoimmune disease and results from destruction of insulin producing beta cells in islet tissues of pancreas by the body’s immune system. The subsequent lack of insulin results in high blood glucose levels, which if not controlled by exogenous insulin results in multiple organ damage. Type 2 diabetes: formerly called non-insulin-dependent (NIDDM) and adult-onset. It is a metabolic disorder that mainly occurs in individuals over the age of 40. In this type of diabetes high blood glucose results either due to relative insulin deficiency or insulin resistance. Lifestyle and genetic factors play an important role in the development of type 2 diabetes. Type 2 diabetes is a growing problem among the elderly population and is widely predicted to grow in the future. Since the population is aging in the western world, so it is not surprising that elderly population will contribute to future increase but other factors such as lifestyle and diet will also play a major role. WHO survey 2010 estimated that 285 million of the world’s population have diabetes and more than 70% of them live in low and middle income countries. It is also estimated that this burden will increase to 438 million by 2030 (Diabetes fact, 2011). Wild 2004 projected that the total number of individuals with diabetes worldwide will increase from 171 million in 2000 to 366 million 2030. Although the prevalence of diabetes is higher in men compared to women but there are more women with diabetes than men. In developing countries type 2 diabetes mainly affects people of working age, between 35 and 64 years, whereas in developed countries the majority of people with diabetes are above the age of retirement i.e. above 65 years of age (WDD06 – Karachi, 2006). India has the largest diabetes world’s population i.e. 50.8 million followed by China with 43.2 million ( Express news report, 2009). In Europe prevalence of clinically diagnosed diabetes was estimated to be 3% in 1997. It was estimated to increase to around 3.6% by 2000 and to over 4% by 2010 (Scottish Diabetes Survey 2003). In UK 4.26 % of population has diabetes according to the Diabetes UK statistics (Diabetes prevalence 2010). Scottish Diabetic Survey, 2010, projects that 4.6% of Scotland population has diabetes out of which 87.7% have type 2 diabetes. Diabetes is also at an increase among children. Diabetes amongst children is primarily Type 1 diabetes but Type 2 diabetes is also increasingly being diagnosed. One of the major contributing factors for this rise in diabetes among children is the increase in the number of children who are overweight or obese. â€Å"Twenty five children in every 100,000 in Scotland have diabetes, compared to 17 in England and Wales.† An increase in this at a rate of 2% per years has been suggested by Diabetes UK in Scotland, as a result tripling of new cases in the last 30 years has been seen (ABPI Report Scotland, 2005). Economic burden of Diabetes for families and society: Diabetes and its complications have a significant economic impact on individuals, families, health systems and countries. For example, WHO estimates that in the period 2006-2015, China will need to allocate $558 billion in foregone national income due to heart disease, stroke and diabetes alone and India will spend $336.6 billion (Diabetes, 2011). â€Å"In the poorest countries, people with diabetes and their families bear almost the whole cost of the medical care they can afford.† In Latin America, 40-60% of medical care expenditures is paid by the families themselves. In Mozambique, 75% of the per capita income is spent on diabetic care by one person; in Mali it amounts to 61%; Vietnam is 51% and Zambia 21%. It is estimated that poor people with diabetes in some developing countries spend as much as 25% of their annual income on private care (Diabetes fact. April 2011). The trend of diabetes in developing countries show that it mostly affects working age group, between 35 and 64 years, relative to developed countries where the majority of diabetes population are aging. Therefore when principal wage earner is affected by diabetes and its complications, the choice between healthcare expenses and food or clothing can trap the whole family in a downward spiral of worsening poverty and health. According to WHO, an annual 2% reduction in chronic disease death rates in Pakistan would provide an economic gain of 1 billion dollars over the next 10 years (WDD06 – Karachi, 2006). The cost incurred by diabetes morbidity are far greater than the cost of the disease prevention (Editorial in Lancet: World Diabetes Day 14th November, 2010). In a press report by the independent economic consultancy group NERA it is assessed that intensive management of Type 2 diabetes in Scotland can decrease hospital cost by ?41 million by saving over 91,000 bed days a year in 2025 and will also save ?78 million a year in lost work days (ABPI Report Scotland, 2005). Diabetic Nephropathy: The diabetic complication, nephropathy is a condition with high unmet therapeutic needs. It is linked with significant increases in morbidity and mortality risk, and is the most common cause of ESRD in the Western countries. Diabetes-induced damage in the kidney leads to microalbuminuria. This progresses to ESRD, which requires dialysis or transplantation. Diabetes accounts for over 40% of ESRD (Diabetic Nephropathy, 2003). The main focus of therapy in diabetic nephropathy is on tight control of blood pressure. Guidelines have progressively revised the target BP goal downwards, currently at 125/75 mmHg in patients with 1g proteinuria, and now recommend either ACE or ARB (Diabetic Nephropathy, 2003). In the U.S., diabetic nephropathy accounts for about 40% of new cases of ESRD. In 1997 the cost required for treatment of diabetic patients having ESRD amounts to $15.6 billion. There is considerable racial/ethnic variability in this regard, Native Americans, Hispanics (especially Mexican-Americans), and African-Americans have much higher risks of developing ESRD than non-Hispanic whites with type 2 diabetes (Mark, 2001). In the UK, 1,000 people with diabetes start kidney dialysis every year. (Diabetes in the UK, 2004). Ahmedani 2005 reports that in Karachi, Pakistan overall prevalence of microalbuminuria was found to be 34% in patients with diabetes and this was strongly associated with the age, diastolic hypertension, diabetic retinopathy and serum low density lipoprotein. End stage renal disease is a most serious complication of diabetes and accounts to be the most expensive for NHS. Diabetic nephropathy usually develops 15-25 years after the occurrence of diabetes. In Scotland, 20% of patients who undergo renal transplantation are diabetic. In diabetic individuals, microalbuminuria and stroke, or an increased serum creatinine levels raises the risk of renal nephropathy and failure. Poor glycemic control and high blood pressure are risk factors of diabetic renal disease (Scottish Diabetes Framework, 2002). Diabetic renal impairment is a strong indicator of Cardiovascular disease and cardiovascular disease is the major cause of morbidity and mortality is diabetic patients (Guillausseau, 2011). Annual cardiovascular mortality is 0.7% in normoalbuminuric patient as compared to 2% in microalbuminuric patients and 12% in the patient with elevated creatinine (Stratton IM, 2009) In a review by Vishwanathan, 1999, it is explained that South Asians and Afro-Caribbean are more susceptible to develop renal disease relative to European. Retinopathy increases the risk of diabetic nephropathy. Prevalence of diabetic nephropathy in India was 30.3% in a study done among 4837 patients with chronic renal failure over a period of 10 years. He further argued that an increased prevalence of microalbuminurea among South Asians having type 2 diabetes mellitus relative to Europeans by 1.2 (men) and 1.7 (women) folds. According to SIGN 116, the incidence of diabetic nephropathy in patient with type 1 diabetes can be considerably reduced by attaining good glycaemic and tight blood pressure control.  ­ In a report by Singh NP, 2003, it is suggested that the incidence of diabetic kidney disease can be reduced by: tight blood glucose control, blood pressure control, rennin-angiotensin-aldosterone system blockade and protein restriction. Causes of microvascular damage in diabetes: Long standing hyperglycemia lead to a number of damages including: Advanced glycosylated end products (AGES) Oxidative stress Increased sorbitol (polyol pathway) Increase in hexosamine pathway Impaired endothelial function Immune effect All these damages result in microvascular complications of diabetes. Advanced glycosylated end-products (AGEs): Chronic hyperglycemia causes increased glycosylation of proteins leading to AGEs, which in turn results in loss of structure and function, turning on/off signal pathways within cells and alteration in gene expression. AGEs are sugar-derived compounds, glucose binds amino groups on proteins, lipids and nucleic acids to form AGEs. AGEs form at a constant but slow rate throughout your life (even as an embryo) (Peppa et al, 2003). AGEs interact with RAGE (surface AGE-binding receptors) resulting in proinflammatory effects, formation reactive oxygen species, loss of oxidants (oxidative stress) and altered gene transcription. Levels of AGEs relates to extent of microvascular complications in diabetes. AGEs contributes to atheromatous plaque by stimulating low-density lipoprotein (LDL) oxidation and the deposition of oxidized LDL. AGEs leads to endothelial dysfunction, macrophage activation, and impaired vascular smooth muscle cell function. Experimentally, AGEs cause glomerular damage and proteinuria. Oxidative stress and Reactive Oxygen Species (ROS): Oxidative stress is an imbalance between ROS production and antioxidants. Oxygen is used by cells to carry out their normal functions and as a side effect produces free radicals. Free radicals are missing an electron so are unstable and highly reactive. Free radicals steal electrons from molecules within cells causing oxidative damage to proteins, membranes and genes. Polyol pathway/aldose reductase: Aldose reductase (AR) normally reduces toxic aldehydes into inactive alcohols inside the cells. Glucose perfuses into some cells without insulin e.g. nerves. During hyperglycaemic condition, AR reduces that excess glucose to sorbitol (a polyol). Polyols are trapped inside the cells creating an osmotic gradient. Sodium and water flow into the cell resulting in oedema. But sorbitol can be metabolised to fructose by the actions of sorbitol dehydrogenase. High fructose leads to AGEs resulting in more cell damage (Takaqi et al, 1995). Hexosamine pathway: Glucose is mainly metabolised through glycolysis, some gets diverted into an alternative pathway, ending up as UDP (urine diphosphate) N-acetyl glucosamine. This alters transcription factors, often leading to pathologic changes in gene expression e.g. increased expression of transforming growth factor-B1 and plaminogen activator inhibitor-1, which damages blood vessels. Endothelial dysfunction – pathogenesis: Hyperglycemia leading to the formation of AGEs, ROS, the glycosylation of proteins and increased inflammatory cytokines etc. As a result small blood vessels, particularly the endothelium are damaged causing vasoconstriction, ischemia, and reduced flow to tissues that rely on the vessel for oxygen and nutrients. Growth factors are also released leading to the blood vessel wall thickening and occlusion of small blood vessels. Nerve growth factors (NGF) and factors like it are damaged. These factors keep nerves healthy and capable of re-growth if damaged. Changes to the immune system lead to release of toxic cytokines, blockage of blood vessels with leukocytes and loss of normal immune cell action. In this dissertation, a recent aspect of one of the above causes of microvascular damage of diabetes leading to nephropathy will be considered. Current studies have uncovered new insights in the role of oxidative stress in diabetic renal disease, suggesting a different and innovative approach to a possible â€Å"casual† antioxidant therapy. In this dissertation the role oxidative stress may play in the development of diabetic kidney disease will be discussed. The role of antioxidant therapy in managing or delaying the progression of diabetic nephropathy will be addressed.

Rebellion Essays (1749 words) - American People Of German Descent

Rebellion ?Rebellion in the Fifties? During the Fifties the United States was filled with confidence but at the same time insecurity. The United States emerged from WWII as a global superpower and a symbol for freedom. The United States saw its role in world affairs as the protector of free countries from communism. The fear of communism expansionism during the fifties was a major issue. Communism represented radical thinking and ideas, a shift away from conservatism thinking or a shift away from the center, to a shift towards the edge. During the Fifties the fear of communism spreading in America gave rise to movements such as McCarthyism and the House on un-American Activities (HUAC). These movements represented the feelings of Americans towards communism at the time, they represented fear and the way to contain their fears was to weed out the bad seeds. These movements created a shift towards the center again, towards conservatism. This trend towards the center or conservatism can be seen in all aspects of American l ife. Not only was conservatism evident in the Fifties, but also rebellion. The push to be conservative and persecute individualism was an immense undertaking that it created fear and out of that fear came rebellion. In any controlled environment, such as the one the United States created for itself during the Fifties, there is bound to be some kind of tension or rebellion, rebellion against the pressure of being normal or conservative. There was a great deal of stress being placed on being ?just like everyone else?. The voice of the rebellion was usually the entertainers, artists, or writers. Many of these people expressed their feelings about current issues by disguising it in their stories, movies or, paintings. Many of these people challenged the politics of the mainstream or the center. However there were works done that supported the shift towards the center and conservatism. Three works that will be examined are Kurt Vonnegut's, ?Player Piano?, the movie, ?Rebel Without a Cause?, and Jack Kerouac's, ?On the Road?. In Kurt Vonnegut's novel, ?Player Piano?, many similarities can be seen between the post-war period in the novel and post WWII in America. In post WWII America there was an extreme shift towards conservatism and an extreme prejudice towards communism. In the post-war period in the novel there was also an extreme shift towards conservatism, but instead of an extreme prejudice towards communism there was an extreme prejudice towards sabotage. Sabotage and communism can be interchangeable because they both mean radical change or thinking and were ideas or acts that were against conformity and conservatism. Vonnegut used sabotage in place of communism to better describe the situation in his novel, but was actually using his novel to describe the current situation in America. During post WWII, communism was a lurking threat in the world and in America. Many feared that communism would expand its influences into America. This was the same fear that was depicted in Vonnegut's novel, but ins tead of the fear of communism it was a fear of sabotage. In the novel Vonnegut used terms such as ?anti-sabotage laws? and saboteur. In America there was McCarthyism, HUAC, Executive order 9835, and communist. The worst thing anyone could be called during the fifties was a communist, or in Vonnegut's novel, a saboteur because it meant that they were a rebel. Another similarity would be the growing dependence on technology like the atom bomb and EPICAC. They both represent how we have become dependent on technology to fight our wars and do our thinking. The development of Levittowns was also described in the novel as M-17's and how everyone lived in one. Everyone had the same house, had the same furniture, and had the same appliances. In essence everyone was the same, they just had different names. It was these kinds of trends that Vonnegut wrote about to warn the American population of what was happening around them. Vonnegut noted these trends in American society in his novel, predicting what could happen if society continued on this path. America was developing a trend where individuals were no longer recognized; only the whole mattered. Everyone had to be part of the system, if you were not part of the system then

Assessment of LW7082 Corporations and International Business Law Essay

Assessment of LW7082 Corporations and International Business Law Essay Free Online Research Papers Assessment of LW7082 Corporations and International Business Law Essay Discuss the development of the EC programme for the harmonization of Company Law. Explain why that programme was seen as important to the economic development of the European Community and outline the various successes and obstacles encountered by that programme. INTRODUCTION The European Community is also a community of laws. The aim of the harmonisation of laws in the European Community is not focused on the creation of one single European Law in contrast to the Member States. Instead, it focuses on the harmonisation of the national legal system only to the extent which is required for the functioning of the common market. The harmonisation of Company Law was regarded as an essential part of this process. As a result, Company Law is one of the most harmonized legal areas in the European Community. This essay will be mainly divided into three Chapters: First, a brief introduction about the development of EC programme for the harmonization of Company Law. Second, analysis and consideration will be given to explain why this harmonization programme was seen as important to the economic development of the European Community. Finally, discussion will focus on the successes the Company Law harmonization programme has achieved and the obstacles it encountered. CHAPTER 1. DEVELOPMENT OF THE EC COMPANY LAW HARMONISATION PROGRAMME The development of the harmonization programme of Company Law in EC can be regarded as the issuing of a series of directives and their applications within EC member states. By harmonizing the company law, the subject was, as Scmitthoff defined as â€Å"salami tactics†, divided into numerous fields, each being regulated by a separate directive. But before we look into those directives, which form the development of EC Company Law harmonization, the legitimate basis of these directives deserves a mention first. 1.1 The legal Foundation of EC Company Law Harmonization The legitimacy of the company law of Europe must be found in the authorizing treaty provisions. The Treaty basis for the company law harmonization programme is particularly Article 44(2) (g) (formerly 54(3) (g)) and, more generally, Articles 94, 95, 293 and 308 (formerly 100, 102, 220 and 235) of the Treaty of Rome. However, the Article 44(2) (g) is of significant importance and plays the primary roles among others, since the majority of the legal bases on Company Law area has been based on that Article. Article 44 (2) (g) set in Chapter 2, â€Å"Right of establishment†, in TITLE III, â€Å"Free movement of persons, services and capital†, provides: â€Å"2. The Council and the Commission shall carry out the duties devolving upon them under the preceding provisions, in particular: †¦ by coordinating to the necessary extent the safeguards which, for the protection of the interests of members and other, are required by Member States of companies or firms within the meaning of the second paragraph of Article 48 with a view to making such safeguards equivalent throughout the Community; † Article 94, set in the chapter on the approximation of laws, require the Council, acting unanimously, to issue directives â€Å"for the approximation of such laws, regulations or administrative provisions of the Member States as directly affect the establishment or functioning of the common market.† 1.2 The Directives of Harmonization Programme of EC Company Law According to Article 44, the Council shall act in the fields which that Article covers by way of directives. But in the first stage of EC Company Law Harmonization Programme, it is as always, when the harmonization of laws is attempted, progress was very slow and involved great effort. The first Commission Proposal for a Publicity Directive dates from the beginning of 1964, and the issuing of this First Directive in 1968 marked the beginning of the EC harmonization in Company Law. The first directive sought to harmonize publicity requirements applying to companies, the circumstances in which company transactions will be valid and the rules relating of the nullity of companies. Eight years later, the 2nd Directive followed dealing with the formation of public limited liability companies and the maintenance and alteration of their capital. In tenor and approach it differs from the First Directive: many of the provisions lay down detailed procedural requirements rather than simply directing the Member States to legislate to a certain end. Thus it has been criticized by some commentators for that reason. However the Second Directive is undeniably of major importance, constituting a significant step towards company law harmonization in the European Community. Following the Second Directives, it did not take too long for the Third and Fourth Directives to be issued. The Third company law Directive can be regarded as having presented a new framework for exercising cross-border collaborative economic activities. It provided for co-ordination of procedures applying to internal mergers within a Member States. The Fourth Directive dealt with disclosure of financial information and the contents of a company’s annual accounts. It complements the First Directive and is supplemented by the Seventh Directive which deals with group accounts. After that, it took another six years until the Sixth, Seven and Eighth Directives came into force. The Sixth Directive 1982 (on division of public companies) deals with the division of an existing public company into entities. The allocation of assets and liabilities among the various beneficiary companies require specific provisions to protect creditors. Member countries are not obliged to introduce this form of reconstruction but, if it is used, the process must be in conformity with the Directive. The Seventh Directive specifies how and in what circumstances consolidated accounts are to be prepared and published by companies with subsidiaries. The Eighth Directive deals with the qualifications and independence of auditors of both public and private companies. It places an obligation on Member States to ensure that auditors are independent and properly carry out their task of auditing company accounts. From the long-lasting intervals of issuing these Company Law Directives mentioned above, we can see that the process of the first stage of EC company law Harmonization programme was slow. In the beginning of the harmonization process only six Member States with six legal systems and traditions had to be considered. The legal system of these Member States based mainly on common continental European legal principles. Later, with the expansion of the European Community, the legal systems of new Member States had to be considered. Hence, the process of harmonization became more difficult. However, until 1984 still five more directives followed. In 1985 the Commission made a new start, and company law developments were given renewed momentum. In a way, this is rather surprising, for â€Å"the White Book decided upon a new approach to harmonization, i.e. abandoning the idea of uniformity and attributing equal value and mutual recognition to national legal provisions instead.† Ha ving written â€Å"less harmonization† upon its banner, the Commission paradoxically achieved more progress with general, and particularly company law harmonization than anyone had previously considered possible. So, after 1984 the harmonization process came to a turning point. As a result the Eleventh Directive and the twelfth Directive were passed in 1989. The Eleventh Directive mainly deals with disclosure requirements in respect of branches opened in a Member State by certain types of companies governed by the law of another state. The Twelfth Directive allows the operation of one-member private companies. Although both directives had considerable implication on German Corporate Law they were of a less general and fundamental approach than the First Directives. So far, there are five more directives that have not yet been passed by the European legislators. The Draft Fifth Directive dealing with corporate structure and worker participation has been the subject of much controversy. One of the most difficult topics in the Fifth Directive is the latter one, â€Å"employee participation in corporate decision-making†. The Draft Ninth Directive deals with certain aspects of groups of companies and the relationship between the participating corporations. The Proposed Tenth Directive concerns cross-border mergers and is progressing no further because fears have been expressed that a cross-border merger could be a way of escaping from worker participation provisions. The Proposed Thirteenth Directive deals with takeovers and is influenced by the City of London takeover code. Finally, the Proposed Fourteenth Directive deals with the Relocation of Registered Office. Besides these Directives known under their numbers, there are some other directives which played a very important role in the EC Company Law Harmonization. For example, The Major Shareholdings Directive focuses on the disclosure of interests in shares. The Insider Dealing Directive, which was implemented in the United Kingdom by Part V of the Criminal Justice Act 1993, with its concise provisions to deal with share market abuse in general and to improve enforcement, virtually placed the investors on an equal footing. Also, a Directive was proposed in 2001 to deal with share market abuse in general and to improve enforcement. From analyzing those directives in EC Company Law Harmonization Programme, it is obvious that a lot of achievements have been made, such as nullity, minimum capital, disclosure and publicity requirements, mergers of public companies and accounts. However, it is still too early to regard that this programme as successful. Some controversial areas such as management structure, employee participation, groups and international mergers?are still pending. They are what EC and Member States should work on in the future of harmonization programme. 1.3 The suitability of directives as the instrument of harmonization By virtue of Article 54 of the Treaty, the Council, in order to attain the effectiveness of the freedom of establishment, â€Å"shall act by means of directives†. The use of the directive as an instrument has both advantages and disadvantages. Traditionally, the general view is that the advantages predominated. These advantages are flexibility and greater freedom of movement for member states, which makes it easier to introduce Community rules into their national laws. This flexible character of directive has many advantages: in a multicultural, multilingual economic area, agreements on common principles of Company Law can be reached without having to agree about the precise wording in the actually applicable provision. It allows bridging the considerable differences in the legislative traditions of the Member States, and also allows each state to use its own wording and language, as the directive only binds as to its result, not as to its forms and methods. For these and ot her reasons, there is a greater readiness to agree upon directives. As Hopt wrote: â€Å"the use of directives does, of course, not preclude the possibility of very detailed regulation, nor does it mean that national legislators may not be well advised in particular cases to follow the text of the directives more or less verbatim. The directive may also go into so much detail that member states have little practical alternative to taking over the directive verbatim.† On the other hand, the Directives still bear some disadvantages as well. The problem arises especially when we look into those particular areas which require comprehensive regulations. Although the directives leaves a degree of discretion to Member States for its transformation, many of them lay down merely the minimum standards to achieve the result specified in those directives. Some of them, such as the Fourth, Seventh and Twelfth Directives, are in the form of a framework for the regulation of a particular matter, as Member States may well introduce additional provisions to create differences between national laws. This fact will inevitably raise the problem of â€Å"blocking effect† from Company Law directives. That is, on the one hand, those directives must be detailed in order to cover multiple aspects of particular matters. However, the detailed provisions may lead to a â€Å"block effect†. Additionally, despite the detail in the directives there still exist s ignificant differences between company regimes in Member States. 1.4 Adoption of Regulations in EC Company Law Harmonization Programme The common market implies the creation of Europe-wide companies, which must be able to act throughout the Community in the same way as in their own country. It thus requires making available new forms of association and co-operation. Therefore, the process of harmonization has always been accompanied by â€Å"a process aiming at the creation of supranational regulations†. The use of regulation for harmonization has considerable advantages. Firstly, unlike the directive, it does not need, any further implementation at national level, thus avoiding long process of adoption of the Community provision by Member States. Secondly, being directly and equally applicable all over the Community, the regulation serves to ensure the same features all over Europe. Also, some disputes about the interpretation of the regulation ultimately have to be submitted to the European court, leading to a more uniform interpretation. In 1985, with the Regulation on the European Economic Interest Grouping (EEIG) a new model for a supranational corporation was introduced. In order to accelerate the introduction of the EEIG the European legislator focused only on the provisions with European background and therefore the national Corporate Laws of the Member States still apply. It is argued that Due to the application of national law besides the provisions of the regulation, the EEIG could not provide the sufficient flexibility and legal certainty that was expected by introducing supranational corporations. At the conference of Nice in December 2000, the Member States finally agreed on the introduction of the European Company or Societas Europaea (the â€Å"SE†). The Regulation on the Statue for a European Company has been adopted by the Council on 8 October 2001. Its virtue is to provide companies that want to act or establish themselves in another Member State with the option of being subject to one set of legislation. Besides these two most important regulations mentioned hereinabove, other Regulations, such as Insolvency Proceedings Regulation and International Accounting Standards Regulation, also make considerable contribution to the EC Company Law Harmonization Programme. CHAPTER 2. The reasons why EC Company Law Harmonization Programme was seen as important to the economic development of European Community Article 2 of the Treaty indicates that its footstone and aim are the establishment of a common market. For that purpose, the activities of the Community are to include the abolition as between Member States, of obstacles to the free movement of goods, persons, services and capital and the approximation of the laws of Member States to the extent required for the functioning of the common market. The divergences in national laws among Member States will cause a lot of problems and can frustrate the functioning of the internal market. The primary reason is that competition can be distorted. The establishment of companies or other enterprise entities will bring in a lot of relevant attractive economic effectiveness, such as tax revenues, expansion of employment, market development and innovation, shareholder and investor interest, etc. If national company laws governing importance areas of creditor and shareholder protection and company management are fundamentally different, this may be expected to create a European â€Å"Delaware effect†, encouraging the establishment of new companies in those Member States with the most attractive and laxest laws and policy. It will then run contrarily to the economic efficiency, since corporate decisions of cross-border establishment and activities should be solely taken on the economic grounds without being significantly influenced by the relative burden of domestic regulation. Different laws will definitely impose administrative and legal burdens on companies with subsidiaries in several Member States. Once companies are free to move their seat or registered office to another Member State, it should be ensured that members and creditors are not prejudiced by the relocation. With the Harmonization of Company Law in European Community, equivalent creditor and shareholder protection should encourage cross-border credit, corporation and investment, thus the economic development of European Community as a whole can be expeditious and rational. What should be mentioned here is that, regulations play an indirect but important part in the economic development of European Community. For example, The Regulation on the European Economic Interest Grouping (EEIG) has created a new type of co-operation, which enables companies in one Member State to co-operate in a joint venture with companies or legal persons in other Member States. Moreover, European Company Statue Regulation (the SE) is of central importance. It enables companies to act throughout the Community in the same way as in their own country. The regulation, in a sense, can insure that all the Member Countries in EC would have available the same basic structure for a company’s establishment and business, no specific States would prevail over others. In this way, the EC Member States can pursue their economic development in a fair and healthy environment. It can be seen as one of the major successes of that more than 30 years old programme. CHAPTER 3. The Successes and Obstacles of EC Company Law Harmonization Programme As mentioned hereinabove, the aim and virtue of the EC Company Law Harmonization, which are reflected in the provisions of the Treaty, is the establishment of a common market. It can be said that the Programme, from its beginning, focused on â€Å"the prevention of the so-called Delaware-effect in the European Community†. The successes of this Programme are obvious and impressive. 3.1 Adoption and Implementation of EC Directives within national legislation. Most of the directives are agreed and adopted among the Member States, which can be seen as the symbol of the significant realization of EC Company Harmonization. The directives in respect of nullity, minimum capital, disclosure and publicity requirements, mergers of public companies and accounts, have been adopted. Most of them have been implemented within the level of national legislation in either some or all EC Member States. 3.2 The breach of legislative barrier among Member States. As mentioned in CHAPTER 2 of this essay, the process of EC Company Law Harmonization is also a process to break down the legislative barrier among the Member States. The harmonisation programme will directly facilitate the free movement of goods, persons services and capital, which will ultimately benefit the creation of a common market. 3.3 The Achievements of Right of Establishment. Because of the absence of an overriding European regulation and the great importance of this issue for the freedom of establishment of firms in the EU, the European Court of Justice (ECJ) has been confronted with this issue at several occasions. In its first decision (Daily-Mail) of 1989, the ECJ held that the right of establishment does not include the right of a company incorporated under the legislation of a Member State to transfer its central management and control to another Member State. Later, with the judgments of the ECJ in Centros and ÃÅ"berseering cases, the circumstances of an legislative competition have fundamentally changed. Due to the Courts displayed, wider understanding of the right of establishment, companies can now move their central management and control from one Member State without the need for further proceedings. In effect, the ECJ has given the right of establishment a â€Å"radically new, wider interpretation†. A company can now be found in a M ember State without having later any further relations to it, which has been a central obstacle to legislative competition in the past. However, the Harmonization Programme which lasting over the past 30 years has inevitably arise some question and controversies. They laid the stumbling block for further progress of this programme. Certain criticism of the company law harmonization programme has been mentioned above CHAPTER 1.3, in respect of the suitability of directives as the instrument of harmonization. Apart from that controversy, this programme also encountered some other obstacles. 3.4 Inefficiency of Directive Implementation The necessity to implement a directive in order to make it more effective in national law sometimes causes problems of inefficiency. Although the European Court of Justice has recognized the direct effect of directives against Member States, this implementation duty is still a weakness, since directives â€Å"have no horizontal direct effect, i.e. in relations between individuals.† Moreover, since directives are directly addressed to Member States but not to companies directly, directives do not provide directly enforceable rights to the companies, to investors or other stakeholders. 3.5 Comprehension and Communication of legal Concepts. A particular problem in seeking to harmonize the Company laws among Member States with disparate legal traditions is the difficulty in dovetailing legal concepts. A directive may focus on an area in which specific concepts are familiar to one State’s understanding of the law but alien and hard for another legal culture to comprehend. For example, the concept of the company organ introduced into Community company law, which was borrowed from German Law, is familiar to the states whose legislation is originated from the Napoleonic code but uneasy for the United Kingdom to analyze the company transactions within the framework of agency. Also, similar problems arise from the use of terms which may not be sufficiently proximate in the different language versions of a directive and in the Member States’ implementation. 3.6 The restrictions of fields harmonized in Directives Criticisms have been directed at the Commission’s priorities for the subject of adopted directives or the undertakings which are subject to them. For example, the pattern of incorporation as public and private companies in the different Member States is significantly different. The Second Directive, which is restricted to public companies, can obviously distort the harmonizing effect of measures applying only to one category of companies. The United Kingdom and Germany, for example, have relatively small numbers of public compared to private companies. 3.7 The problem of compromises in the EC legislative processes In the beginning of the harmonization process only six Member States with six legal systems and traditions had to be considered. The legal system of these Member States based in part on common continental European legal principles. Due to the growth in number of Member States, compromises have always been difficult to reach. Hence, the process of harmonization faced with stagnation. At the conference of Nice, the Member States tried to handle this problem by simplifying the legislative process. But these amendments and institutional reforms will most likely not be able to solve this stagnation problem. While the future of the following directives and other legislative acts are uncertain, the existing Directives and Regulations about corporate law will- taken by themselves be hard to change. CONCLUSION Having evaluating the EC programme for the harmonization of Company Law, it can be concluded that the overall progress is impressive. However, it is yet too early to say that this programme is an absolute success. The Commission acknowledges that there is much work remaining to be done regarding the legal framework for company law. There still exist the problems such as the complete freedom of establishment of companies â€Å"in a strict sense† , sufficient protection of creditors and shareholders. Moreover, the rules relating to takeovers and the board are important elements of company law, and harmonisation cannot be brought much further before the conflicts in these areas are resolved. What has been achieved so far for this Harmonization Programme will become the history for tomorrow, what should be done now and in future is more important and crucial for legislators to consider, on both European Community and national legal system levels. Taking for reference the past achievement and obstacles, we are awaiting the further progress and achievements of EC Company Harmonization Programme.

Polygons on ACT Math Geometry Formulas and Strategies

Polygons on ACT Math Geometry Formulas and Strategies SAT / ACT Prep Online Guides and Tips Questions about both circles and various types of polygons are some of the most prevalent types of geometry questions on the ACT. Polygons come in many shapes and sizes and you will have to know them inside and out in order to take on the many different types of polygon questions the ACT has to offer. The good news is that, despite their variety, polygons are often less complex than they look; a few simple rules and strategies are all that you need when it comes to solving an ACT polygon question. This will be your complete guide to ACT polygons- the rules and formulas for various polygons, the kinds of questions you’ll be asked about them, and the best approach for solving these types of questions. What is a Polygon? Before we go to polygon formulas, let’s look at what exactly a polygon is. A polygon is any flat, enclosed shape that is made up of straight lines. To be â€Å"enclosed† means that the lines must all connect, and no side of the polygon can be curved. Polygons NOT Polygons Polygons come in two broad categories- regular and irregular. A regular polygon has all equal sides and all equal angles, while irregular polygons do not. Regular Polygons Irregular Polygons A polygon will always have the same number of sides as it has angles. So a polygon with nine sides will have nine angles. The different types of polygons are named after their number of sides and angles. A triangle is made of three sides and three angles (â€Å"tri† meaning three), a quadrilateral is made of four sides (â€Å"quad† meaning four), a pentagon is made of five sides (â€Å"penta† meaning five), etc. Many of the polygons you’ll see on the ACT (though not all) will either be triangles or some sort of quadrilateral. Triangles in all their forms are covered in our complete guide to ACT triangles, so let’s move on to look at the various types of quadrilaterals you’ll see on the test. Barber shop quartets, quadrilaterals- clearly the secret to success is in fours. Quadrilaterals There are many different types of quadrilaterals, most of which are subcategories of one another. Parallelogram A parallelogram is a quadrilateral in which each set of opposite sides is both parallel and congruent (equal) with one another. The length may be different than the width, but both widths will be equal and both lengths will be equal. Parallelograms are peculiar in that their opposite angles will be equal and their adjacent angles will be supplementary (meaning any two adjacent angles will add up to 180 degrees). Most questions that require you to know this information are quite straightforward. For example: If we draw this parallelogram, we can see that the two angles in question are supplementary. This means that the two angles will add up to 180 degrees. Our final answer is F, add up to 180 degrees. Rhombus A rhombus is a type of parallelogram in which all four sides are equal and the angles can be any measure (so long as their adjacents add up to 180 degrees and their opposite angles are equal). Rectangle A rectangle is a special kind of parallelogram in which each angle is 90 degrees. The rectangle’s length and width can either be equal or different from one another. Square If a rectangle has an equal length and width, it is called a square. This means that a square is a type of rectangle (which in turn is a type of parallelogram), but NOT all rectangles are squares. Trapezoid A trapezoid is a quadrilateral that has only one set of parallel sides. The other two sides are non-parallel. Kite A kite is a quadrilateral that has two pairs of equal sides that meet one another. You'll notice that a lot of polygon definitions will fit inside other definitions, but a little organization (and dedication) will help keep them straight in your head. Polygon Formulas Though there are many different types of polygons, their rules and formulas build off of a few basic ideas. Let’s go through the list. Area Formulas Most polygon questions on the ACT will ask you to find the area or the perimeter of a figure. These will be the most important area formulas for you to remember on the test. Area of a Triangle $$a = {1/2}bh$$ The area of a triangle will always be half the amount of the base times the height. In a right triangle, the height will be equal to one of the legs. In any other type of triangle, you must drop down your own height, perpendicular from the vertex of the triangle to the base. Area of a Square $$l^2$$ Or $$lw$$ Because each side of a square is equal, you can find the area by either multiplying the length times the width or simply by squaring one of the sides. Area of a Rectangle $$lw$$ For any rectangle that is not a square, you must always multiply the base times the height to find the area. Area of a Parallelogram $$bh$$ Finding the area of a parallelogram is exactly the same as finding the area of a rectangle. Because a parallelogram may slant to the side, we say we must use its base and its height (instead of its length and width), but the principle is the same. You can see why the two actions are equal if you were to transform your parallelogram into a rectangle by dropping down straight heights and shifting the base. Area of a Trapezoid $$[(l_1 + l_2)/2]h$$ In order to find the area of a trapezoid, you must find the average of the two parallel bases and multiply this by the height of the trapezoid. Let's take a look at this formula in action, The trapezoid is divided into a rectangle and two triangles. Lengths are given in inches. What is the combined area of the two shaded triangles? A. 4 B. 6 C. 9 D. 12 E. 18 If you remember your formula for trapezoids, then we can find the area of our triangles by finding the area of the trapezoid as a whole and then subtracting out the area of the rectangle inside it. First, we should find the area of the trapezoid. $[(l_1 + l_2)/2]h$ $[(6 + 12)/2]3$ $(18/2)3$ $(9)3$ $27$ Now, we can find the area of the rectangle. $6 * 3$ 18 And finally, we can subtract out the area of the rectangle from the trapezoid. $27 - 18$ 9 The combined area of the triangles is 9. Our final answer is C, 9. In general, the best way to find the area of different kinds of polygons is to transform the polygon into smaller and more manageable shapes. This will also help you if you forget your formulas come test day. For example, if you forget the formula for the area of a trapezoid, turn your trapezoid into a rectangle and two triangles and find the area for each. Luckily for us, this has already been done in this problem. We know that we can find the area of a triangle by ${1/2}bh$ and we already have a height of 3. We also know that the combined bases for the triangles will be: $12 - 6$ 6 So let us say that one triangle has a base of 4 and the other has a base of 2. (Why those numbers? Any numbers for the triangle bases will work so long as they add up to 6.) Now, let us find the area for each triangle. or the first triangle, we have: ${1/2}(4)(3)$ $(2)(3)$ $6$ And for the second triangle, we have: ${1/2}(2)(3)$ $(1)(3)$ 3 Now, let us add them together. $6 + 3$ 9 Again, the area of our triangles together is 9. Our final answer is C, 9. Always remember that there are many different ways to find what you need, so don’t be afraid to use your shortcuts! Side and Angle Formulas Whether your polygon is regular or irregular, the sum of its interior degrees will always follow the rules of that particular polygon. Every polygon has a different degree sum, but this sum will be consistent, no matter how irregular the polygon. For example, the interior angles of a triangle will always equal 180 degrees, whether the triangle is equilateral (a regular polygon), isosceles, acute, or obtuse. So by that same notion, the interior angles of a quadrilateral- whether kite, square, trapezoid, or other- will always add up to be 360 degrees. Interior Angle Sum You will always be able to find the sum of a polygon’s interior angles in one of two ways- by memorizing the interior angle formula, or by dividing your polygon into a series of triangles. Method 1: Interior Angle Formula $$(n−2)180$$ If you have an n number of sides in your polygon, you can always find the interior degree sum by the formula $(n - 2)$ times 180 degrees. Method 2: Dividing Your Polygon Into Triangles The reason the above formula works is because you are essentially dividing your polygon into a series of triangles. Because a triangle is always 180 degrees, you can multiply the number of triangles by 180 to find the interior degree sum of your polygon, whether your polygon is regular or irregular. As we saw, we have two options to find our interior angle sum. Let us try each method. Solving Method 1: formulas $(n - 2)180$ There are 5 sides, so if we plug that into our formula for $n$, we get: $(5 - 2)180$ $3(180)$ 540 Now we can find the sum of the rest of the angle measurements by subtracting our known degree measure, 50, from our total interior degrees of 540. $540 - 50$ 490 Our final answer is K, 490. Solving Method 2: diving polygon into triangles We can also always divide our polygon into a series of triangles to find the total interior degree measure. We can see that our polygon makes three triangles and we know that a triangle is always 180 degrees. This means that the polygon will have a interior degree sum of: $3 * 180$ 540 degrees. And finally, let us subtract the known angle from the total in order to find the sum of the remaining degrees. $540 - 50$ 490 Again, our final answer is K, 490. Individual Interior Angles If your polygon is regular, you will also be able to find the individual degree measure of each interior angle by dividing the degree sum by the number of angles. (Note: n can be used for both the number of sides and the number of angles because the number of sides and angles in a polygon will always be equal.) ${(n - 2)180}/n$ Again, you can choose to either use the formula or the triangle dividing method by dividing your interior sum by the number of angles. Number of Sides As we saw earlier, a regular polygon will have all equal side lengths. And if your polygon is regular, you can find the number of sides by using the reverse of the formula for finding angle measures. A regular polygon with n sides has equal angles of 140 degrees. How many sides does the figure have? 6 7 8 9 10 For this question, it will be quickest for us to use our answers and work backwards in order to find the number of sides in our polygon. (For more on how to use the plugging in answers technique, check out our guide to plugging in answers). Let us start at the middle with answer choice C. We know from our angle formula (or by making triangles out of our polygons) that an eight sided figure will have: $(n - 2)180$ $(8 - 2)180$ $(6)180$ 1080 degrees. Or again, you can always find your degree sum by making triangles out of your polygon. This way you will still end up with (6)180=1080 degrees. Now, let us find the individual degree measures by dividing that sum by the number of angles. $1080/8$ $135$ Answer choice C was too small. And we also know that the more sides a figure has, the larger each individual angle will be, so we can cross off answer choices A and B, as those answers would be even smaller. (How do we know this? A regular triangle will have three 60 degree angles, a square will have four 90 degree angles, etc.) Now let us try answer choice D. $(n - 2)180$ $(9 - 2)180$ $(7)180$ 1260 Or you could find your internal degree sum by once again making triangles from your polygons. Which would again give you $(7)180 = 1260$ degrees. Now let’s divide the degree sum by the number of sides. $1260/9$ $140$ We have found our answer. The figure has 9 sides. Our final answer is D, 9. Number of Diagonals $${n(n - 3)}/2$$ It is common for the ACT to ask you about the number of distinct diagonals in a polygon. Again, you can find this information using the formula or by drawing it out (or a combination of the two). This is basically the same as dividing your polygon into triangles, but they will be overlapping and you are counting the number of lines drawn instead of the number of triangles. Method 1: formula In order to find the number of distinct diagonals in a polygon, you can simply use the formula ${n(n - 3)}/2$, wherein $n$ is the number of sides of the polygon. Method 2: drawing it out The reason the above formula works is a matter of logic. Let’s look at an octagon, for example. You can see that an octagon has eight angles (because it has eight sides). If you were to draw all the diagonals possible from one particular angle, you could draw five lines. You will always be able to draw n−3 lines because one of the angles is being used to form all the diagonals and the lines to the two adjacent angles make up part of the perimeter of the polygon and are therefore NOT diagonals. So you can only draw diagonals to n−3 corners. Now, let’s mark another angle’s series of diagonals. You can see that none of these diagonals overlap, BUT if we were to draw the diagonals from an opposite corner, we would have multiple overlapping diagonals. The adjacent angles will not overlap, but the opposite ones will. This means that there will only be half as many diagonals as the total number of angles multiplied by their possible diagonals (in other words half of n(n−3). This is why our final formula is: ${n(n - 3)}/2$ This is all the angles multiplied by their total number of diagonals, all divided by half so that we do not get overlapping diagonal lines. (Note: of course an alternative to using any form of the formula is to simply draw out your diagonals, making sure to be very very careful to not create any overlapping diagonal lines.) Just make sure you don't dizzy yourself keeping track of all your angles and diagonals. Typical Polygon Questions Now that we’ve been through all of our polygon rules and formulas, let’s look at a few different types of polygon questions you’ll see on the ACT. About half of ACT polygon questions you’ll see will involve diagrams and about half will be word problems. Most all of the word problems will involve quadrilaterals in some form or another. Typically, you will be asked to find one of three things in a polygon question: The measure of an angle (or the sum of two or more angles) The perimeter of a figure The area of a figure Let’s look at a few real ACT math examples of these different types of questions. 1. Finding the measure of an angle We know that we can find the degree measure of a regular polygon by finding their total number of degrees and dividing that by the number of sides/angles. So let us find the sum of the interior degrees of our pentagon. A pentagon can be divided into three triangles, so we know that it has a total of: 3(180) 540 degrees. If we divide this number by the number of sides/angles in a pentagon, we can see that each angle measure is: $540/5$ 108 Now, we also know that every straight line is 180 degrees. This means that we can find the exterior angles of the pentagon by subtracting the interior angles from 180. $180 - 108$ 72 We also know that a triangle's interior degrees always add up to 180, so we can find our final angle by subtracting our two known angles from 180. $180 - 72 - 72$ 36 Our final answer is C, 36. 2: Finding the perimeter of a figure We know that a square has, by definition, all equal sides. Because DC is 6, that means that ED, EB, and BC are all equal to 6 as well. We also know that an equilateral triangle has all equal sides. Because EB equals 6 and is part of the equilateral triangle, EB, AE, and AB are all equal to 6 as well. And, finally, the perimeter of the figure is made up of lines DE, EA, AB, BC, and CD. This means that our perimeter is: 6 + 6 + 6 + 6 + 6 30 Our final answer is C, 30. 3: Using or finding the area of the figure We know that the area of a rectangle is found by multiplying the length times the width, and we also know that a rectangle has two paris of equal sides. So we need to find measurements for the sides that, in pairs, add up to 24 and, when multiplied, will make a prouct of 32. One way we can do this is to use the strategy of plugging in answers. Let us, as usual when using this strategy, start with answer choice C. So, if we have a short side length of 3, we need to double it to find how much the short sides contribute to the total perimeter. $3 * 2$ 6 If we subtract this from our total perimeter, we find that the sum of our longer sides are: $24 - 6$ 18 Which means that each of the longer sides is: $18/2$ 9 Now, if one side length is 3 and the other is 9, then the area of the rectangle will be: $3 * 9$ 27 This is too small to be our area. We need the shorter side lengths to be longer than 3 so that the product of the length and the width will be larger. Let us try option J instead. If we have two side lengths that each measure 4, they will add a total of: $4 * 2$ 8 Now let us subtract this from the total perimeter. $24 - 8$ 16 This is the sum of the longer side lengths, which means we must divide this number in half to find the individual measures. $16/2$ 8 And finally, let us multiply the length times the width to find the area of the rectangle. $8 * 4$ 32 These measurements fit our requirements, which means that the shorter sides must each measure 4. Our final answer is J, 4. Now let's look at the strategies for success for your polygon questions (as well as what to avoid doing). How to Solve a Polygon Question Now that we’ve seen the typical kinds of questions you’ll be asked on the ACT and gone through the process of finding our answers, we can see that each solving method has a few techniques in common. In order to solve your polygon problems most accurately and efficiently, take note of these strategies: #1: Break up figures into smaller shapes Don’t be afraid to write all over your diagrams. Polygons are complicated figures, so always break them into small pieces when you can. Break them apart into triangles, squares, or rectangles and you’ll be able to solve questions that would be impossible to figure out otherwise. Alternatively, you may need to expand your figures by providing extra lines and creating new shapes in which to break your figure. Just always remember to disregard these false lines when you’re finished with the problem. If we create and expand new lines in our figure, we can make our lengths and sides a little more clear. We can also see why this works because our red lines are essentially extensions of the perimeter branching outwards in order to give us a clearer picture. Now, we know that, because the bottom-most horizontal line is equal to 20, the sum of all the other horizontal lines is also equal to 20. We can also see that all the vertical lines will add up to: 12 + 8 + 8 + 12 This means that our total perimeter will be: 20 + 20 + 12 + 12 + 8 + 8 80 Our final answer is B, 80. #2: Use your shortcuts If you don’t feel comfortable memorizing formulas or if you are worried about getting them wrong on test day, don’t worry about it! Just understand your shortcuts (for example, remember that all polygons can be broken into triangles) and you’ll do just fine. #3: When possible, use PIA or PIN Because polygons involve a lot of data, it can be very easy to confuse your numbers or lose track of the path you need to go down to solve the problem. For this reason, it can often help you to use either the plugging in answer strategy (PIA) or the plugging in numbers strategy (PIN), even though it can sometimes take longer (for more on this, check out our guides to PIA and PIN). #4: Keep your work organized There is a lot of information to keep track of when working with polygons (especially once you break the figure into smaller shapes). It can be all too easy to lose your place or to mix-up your numbers, so be extra vigilant about your organization and don’t let yourself lose a well-earned point due to careless error. Before you go ahead and put your polygon knowledge to the test, take a moment to bask in some much-needed Cuteness. Test Your Knowledge Now, let's test your knowledge on polygons with some real SAT math examples. 1. 2. 3. 4. Answers: D, C, G, G Answer Explanations: 1. In order to find the number of distinct diagonals, we can, as always, either use our diagonal formula or be very (very) careful to draw our own. Let us try both methods. Method 1: formula ${n(n - 3)}/2$ We have a hexagon, so there are 6 sides. We can therefore plug 6 in for n. ${6(6 - 3)}/2$ $6(3)/2$ $18/2$ $9$ There will be 9 distinct diagonals. Our final answer is D, 9. Method 2: drawing it out If we draw our own diagonals, we can see that there are still 9 diagonals total. We can color-code these lines here, but you will not have that option on the test, so make sure you are both able to draw out all your diagonals and not count repeat lines. When done correctly, we will have 9 distinct diagonals in our hexagon. Our final answer is D, 9. 2. We know that, by definition, a parallelogram has two pairs of equal sides. So if one side measures 12, then at least one of the other three sides must also measure 12. So let us first subtract our pair of 12-length sides from our total perimeter of 72. $72 - 12 -12$ 48 The remaining pair of sides will have a sum of 48. We also know that the remaining pair of sides must be equal to one another, so let us divide this sum in half in order to find their individual measures. $48/2$ 24 This means that our parallelogram will have side measures of: 12, 12, 24, 24 Our final answer is C. 3. We are told that each of these rectangles is a square, which means that the side lengths for each square will be equal. We also know that, in order to find the area of a square, we can simply square (multiply a number by itself) one of the sides. So, if the larger square has an area of 50 square centimeters, that means that one of the side lengths squared must be equal to 50. In other words: $s^2 = 50$ $s =√50$ $s =√25 *√2$ $s = 5√2$ (For more info on how to manipulate roots and squares like this, check out our guide to ACT advanced integers.) So now we know that the length of each of the sides of the larger square is $5√2$. We also know that the area of the smaller square is 18 and that the length of one of the sides of the shorter square is the length of the side of the larger square, minus x. img src="http://cdn2.hubspot.net/hubfs/360031/body_square_example.png" alt="body_square_example" style="display: block; margin-left: auto; margin-right: auto; width: 212px;" width="212" So let us find x by using this information. $(5√2 - x)^2 = 18$ $5√2 - x =√18$ $5√2 - x =√9 *√2$ $5√2 - x = 3√2$ $-x = -2√2$ $x = 2√2$ We have successfully found the length of $x$. Our final answer is G,$2√2$. 4. We have a few different ways to solve this problem, but one of the easiest is to use the strategy of plugging in our own numbers. This will help us to visualize the lengths and areas much more solidly. So let us imagine for a minute that the longest length of our rectangle is 12 and the shorter side is 4. (Why those numbers? Why not! When using PIN, we can choose any numbers we want to, so long as they do not contradict our given information. And these numbers do not, which means we're good to go.) Now, to make life even simpler, let us divide our rectangle in half and just work with one half at a time. Now, because we have divided our rectangle exactly in half (and we know that we did this because we are told that F and E are both midpoints of the longest side of our rectangle), we know that BF must be 6. Now we have four triangles, three of which are shaded. In order to find the ratio of unshaded area to shaded area, let us find the areas of each of our triangles. To find the area of a triangle, we know we need: ${1/2}bh$ If we take the triangle on the left, we already know that our base is 4. We also know that the height must be 3. Why? Because point G is directly in the middle of our rectangle, so the height will be exactly half of the line BF. This means that our left-most triangle will have an area of: ${1/2}bh$ ${1/2}(4)(3)$ $(2)(3)$ $6$ Now, we know that our right-most triangle (the unshaded triangle) will ALSO have an area of 6 because its height and base will be exactly the same as our left triangle. So let us find the areas of our top and bottom triangles. Again, we already have a given value for our base (in this case 6) and the height will be exactly half of the line BA. This means that the area of our top triangle (as well as our bottom triangle) will be: ${1/2}bh$ ${1/2}(6)(2)$ $(3)(2)$ $6$ Both the left and the top-most triangles have an area of 6, which means that ALL the triangles have equal areas. There is 1 unshaded triangle and 3 shaded triangles. This means that the ratio of unshaded to shaded triangles is 1:3. We also know that this will be the same ratio if we were to complete the problem for the other half of the rectangle. Why? We cut the shape exactly in half, so the ratio of all the unshaded triangles to shaded triangles will be: 2:6 Or, again: 1:3 Our final answer is G, 1:3. A little practice, a little flare, and you've got the path down to all your right answers. The Take Aways Once you internalize the few basic rules of polygons, you’ll find that these questions are not generally as difficult as they may appear at first blush. You may come across irregular polygons and ones with many sides, but the basic strategies and formulas will always be the same. Remember your strategies, keep your work well organized, and know your key definitions, and you will be able to take on even the most difficult polygon questions the ACT can throw at you.
