Migration, Immigration, and Emigration, and their Effects on Religion, Research Paper

Migration, Immigration, and Emigration, and their Effects on Religion, Women, and Minorities in the Developing World - Research Paper Example The Paper Egypt serves as one of the most influential and prosperous countries of the entire African continent. Her splendid geographical position, magnificent historical background, rich cultural heritage, sound economic structure and imperative political role in the strategic affairs of the region have earned a distinguished and respectable place for her in the international arena. Being a commercial hub and a significant trade junction, people arrive here from all parts of the continent in order to establish their business and get involved into the activities related to trade and commerce on the one hand, and in search of job and employment on the other. The most important aspect of the country is her geographical location, as Egypt is situated at the junction of three continents including Asia, Europe and Africa. At one side, she appears to be the leader of Africa community, and on the other side, Egypt looks engaged in presenting the case of the Middle East problems. Similarly, she also represents the Islamic world at different occasions, which proves her significance as the representative of several most important regional, religious and political communities of the world. It is therefore, the Egyptian people have developed social and commercial ties with the Asian and European traders, corporate firms and companies. â€Å"Occupying a focal geographic bridge linking Africa and Asia, contemporary Egypt is the inheritor of a civilization dating back more than 6,000 years. Egypt’s strategic location has made it the object of numerous conquests: by the Ptolemies, Romans, Greeks, Arabs, Fatimids, Mamluks, Ottomans, and Napoleon Bonaparte. (Platan & Teal, 2001:1) Though, divergent invaders entered Egypt and subjugated her population by capturing the land, wealth and resources of this ancient civilization, yet the country maintained its identity and distinction as the independent state of the world. It is mistakenly viewed that several ethno-racial group s live in Egypt; however, an overwhelming majority of the masses is Egyptian by race. Egypt has not been famous in history for his magnificent emperors and pharaohs of ancient eras only; rather, the architecture of ancient Egypt also makes it a remarkable society of ancient world. The Egyptian pyramids are included in the Seven Wonders existing on the face of the earth. Besides, her strong economy and established infrastructure have also turned the country an attractive place particularly for the people, belonging to southern, central and western parts of the continent, who arrive Egypt in the same manner as the masses from developed Middle East and Far Eastern countries proceed to Europe in search of superior living standard and career jobs as well. Thus, Egypt is one of the most migrated countries of Africa, where perhaps few countries including South Africa, Nigeria and others surpass her in the area of migration into the country. However, the Egyptians have developed popular tre nd of immigration to the southern Europe and the Middle East states particularly Brunei and the UAE. Actually, immigration to Egypt has religious background too, where in ancient time Prophet Joseph was forced to migrate as a child by his brothers, who had thrown him into a well. However, the entire House

The Ku Klux Klan prevented African Americans from gaining civil rights Essay Example for Free

The Ku Klux Klan prevented African Americans from gaining civil rights Essay The â€Å"Ku Klux Klan† were an Anglo-Saxon based cult who believed solely on white supremacy. The movement was first formed in the 1860’s in order to protect white rights; they mainly formed in the very deep southern states of America. Since starting the â€Å"KKK† has gone through phases of popularity followed by essentially fading in number. However in 1915 the â€Å"KKK† was reestablished with great force, now standing for what they described as Americanism, Christianity and Morality. After this The â€Å"KKK† continued to grow in number up until the late 1960’s, boasting numbers between two and five million members including some important political influence. The â€Å"KKK† mostly used there aggressive manner and force they brought upon the black people. This intimidation stopped the black people from living near white communities and also made sure they would not complain or try to use their rights. This was so affective because the black people were so afraid or murder and torture they did not complain or protest for civil rights, therefore keeping this problem from the rest of America and the world. The â€Å"KKK† were ruthless in the south at this time as they preformed murders and destroyed black communities in order to install such fear that the blacks would keep quiet. Most black people felt so intimidated they couldn’t even vote because of the almost inevitability that the â€Å"KKK† would find out which would result in murders and firebombing of households. The â€Å"KKK† was such a significant group because of the vast amount of members that belonged to the movement, especially in the southern states. The black people could not work out who was a Klan member or not so became scared and untrustworthy of all people, this lead to black even losing faith in the law and American politics. This was because many members and supporters of the Klan were very powerful at the time in America and held some powerful jobs. Senators, judges and police chiefs all potentially could have been Klansmen. This installed an even greater fear into the black people of America. These members also made sure that politically civil rights laws were not passed and in a state bases laws were not even kept. For example Bull Conner had powerful jobs within Birmingham, Alabama and the police chief for that town and due to his known racism made sure that all black citizens of Birmingham were treated badly and were refused freedom of speech, therefore this create d an even bigger state of fear for citizens of Alabama at that time. Many Black people living within Southern states as soon as they saved enough money or sorted out arrangements’ moved form the south to the north were they knew they would be treated fairer. This was made sure by the â€Å"KKK† that there were not enough blacks to even fight for their rights even if they could, for example if they could vote there would not be enough black people to make a difference and made sure that integration into white schools was not a problem. Also if black people were fleeing from the south to the north the â€Å"KKK† had won as they did not want to live amongst them anyway and made sure they knew they had forced them out by their intense persecution. On the other hand, it can be argued that the â€Å"KKK† failed in their overall aim to stop black people from gaining civil rights in America. Schools and collages in both North and South stats became desegregated despite the Klan’s abuse. This proved that no matter what the black population still united and eventually won against this racial Tierney form the â€Å"KKK†. This also proved that still the majority of politicians believed in civil rights and proved that the â€Å"KKK† did not have as much influence within politics as they thought. The obvious other victory of this was that the younger generations began to accept black people as human beings and integrated them into same societies which proved that the â€Å"KKK† could not last forever and once the last of the Klansmen die out there will be very few people to take their places. The â€Å"KKK† might have hindered the progress of civil rights being achieved in some states within southern America but there was still a large part of America who by this times supported civil rights and sympathized with how the blacks were treated in the south by the â€Å"KKK†, this created resentment for the North against the Klan and built up more support and votes for pro civil rights politicians. Therefore in the long run the Klan just hindered themselves and made sure essentially that the black were treated better and given more rights. The influx of many civil rights activist groups such as the NAACP and the SCLC essentially cancelled out the â€Å"KKK† as these groups thanks to the likes of Martin Luther King used clever modern tactics to counteract the Klan’s forces. These groups supported blacks in all areas from peaceful protest to help in the court rooms. The Klan’s unimaginative and predictable methods were no match for the power of things like the media and use of making sympathy for the black people in the south. The NAACP even helped black people get the vote in southern states so. Therefore there were civil rights sympathizes even in southern states. In conclusion, The â€Å"Ku Klux Klan† was a successful movement and stopped many black people from succeeding in gaining Civil Rights mainly in the South. However, In 1964 The Civil Rights Act was passed and therefore could not succeed and never really stopped it, essentially they just succeeded in prolonging this act for a while.

Measures of Dispersion

Measures of Dispersion Summary The measure of central tendency, as discussed in the previous chapter tells us only about the characteristics of a particular series. They do not describe any thing on the observations or data entirely. In other wards, measures of central tendency do not tell any thing about the variations that exist in the data of a particular series. To make the concept, let discuss an example. It was found by using formula of mean that the average depth of a river is 6 feet. One cannot confidently enter into the river because in some places the depth may be 12 feet or it may have 3 feet. Thus this type of interpretation by using the measures of central tendency some times proves to be useless. Hence the measure of central tendency alone to measure the characteristics of a series of observations is not sufficient to draw a valid conclusion. With the central value one must know as to how the data is distributed. Different sets of data may have the same measures of central tendency but differ greatly in terms of variation. For this knowledge of central value is not enough to appreciate the nature of distribution of values. Thus there is the requirement of some additional measures along with the measures of central tendency which will describe the spread of the entire set of values along with the central value. One such measure is popularly called as dispersion or variation. The study of dispersion will enables us to know whether a series is homogeneous (where all the observations remains around the central value) or the observations is heterogeneous (there will be variations in the observations around the central value like 1, 50, 20, 28 etc., where the central value is 33). Hence it can be said that a measure of dispersion describes the spread or scattering of the individual values of a series around its central value. Experts opine different opinion on why the variations in a distribution are so important to consider? Following are some views on validity of the measure of dispersion: Measures of variation provide the researchers some additional information about the behaviour of the series along with the measures of central tendency. With this information one can judge the reliability of the value that is derived by using the measure of central tendency. If the data of the series are widely dispersed, the central location is less representatives of the data as a whole. On the other hand, when the data of a series is less dispersed, the central location is more representative to the entire series. In other wards, a high degree of variation would mean little uniformity whereas a low degree of variation would mean greater uniformity. When the data of a series are widely dispersed, it creates practical problems in executing data. Measure of dispersion helps in understanding and tackling the widely dispersed data. It facilitates to determine the nature and cause of variation in order to control the variation itself. Measures of variation enable comparison to be made of two or more series with regard to their variability. DEFINITION: Following are some definitions defined by different experts on measures of dispersion. L.R. Connor defines measures of dispersion as ‘dispersion is the measure extended to which individual items vary. Similarly, Brookes and Dick opines it as ‘dispersion or spread is the degree of the scatter or the variation of the variables about a central value. Robert H. Wessel defines it as ‘measures which indicate the spread of the values are called measures of dispersion. From all these definition it is clear that dispersion measures more or less describes the spread or scattering of the individual values of a series around its central value. METHODS OF MEASURING DISPERSION: Dispersion of a series of data can be calculated by using following four widely used methods Dispersion when measured on basis of the difference between two extreme values selected from a series of data. The two well known measures are The Range The Inter-quartile Range or Quartile Deviation Dispersion when measured on basis of average deviation from some measure of central tendency. The well known measures are The Mean/average deviation The Standard Deviation and The Coefficient of variation and The Gini coefficient and the Lorenz curve All the tools are discussed in details below one after the other. THE RANGE: The range is the simplest measure of the dispersion. The range is defined as the difference between the highest value and the lowest value of the series. Range as a measure of variation is having limited applicability. It is widely used for weather forecasting by the meteorological departments. It also used in statistical quality control. Range is a good indicator to measure the fluctuations in price change like that of studying the variations in the price of shares and debentures and other related matters. Following is the procedure of calculating range: Range= value of the highest observation (H) – value of the lowest observation (L) or Range = H – L Advantages of Range: Range is the simplest of obtaining dispersion. It is easily understandable and can be interpreted easily. It requires fewer times to obtain the variation in the series. Disadvantages of Range: As it considers only two extreme values, hence it doesnt include all the observations of the series. It fails to tell any thing about the characteristics of a distribution It is having very limited scope of applicability Having no mathematical treatment THE INTER-QUARTILE RANGE OR QUARTILE DEVIATION: A second measure of dispersion is the inter-quartile range which takes into account the middle half i.e., 50% of the data thus, avoiding the problem of extreme values in the data. Hence it measures approximately how far from the median one must go on either side before it can be include one-half the values of the data set. Inter-quartile range can be calculated by dividing the series of observations into four parts; each part of the series contains 25 percent of the observations. The quartiles are then the highest values in each of these four parts, and the inter-quartile range is the difference between the values of the first and the third quartile. Following are the steps of calculating the inter-quartile range: Arrange the data of the series in ascending order. Calculate the first quartile which is denoted as (Q1) by using the formula In case of grouped data the first quartile (Q1) can be calculated by using the formula Where N= number of observations in the series i.e., the sum of frequencies, L = lower limit of the quartile class, p.c.f. = commutative frequency prior to the quartile class, f = frequency of the quartile class and i = class interval. Quartile class can be determined by using the formula. Calculate the third quartile which is denoted as (Q3) by using the formula in case of ungrouped data. In case of grouped data the third quartile (Q3) can be calculated by using the formula Where N= number of observations in the series i.e., the sum of frequencies, L = lower limit of the quartile class, p.c.f. = commutative frequency prior to the quartile class, f = frequency of the quartile class and i = class interval. Quartile class can be determined by using the formula. THE MEAN/AVERAGE DEVIATION: Mean/average deviation is the arithmetic mean of the difference of a series computed from any measure of central tendency i.e., either deviation from mean or median or mode. The absolute values of each observation are calculated. Clark and Schekade opine mean deviation or average deviations as the average amount of scatter of the items in a distribution from either the mean or the median, ignoring the signs of the deviations. Thus the average that is taken of scatter is an arithmetic mean, which accounts for the fact that this measure is often called as mean deviation or average deviations. Calculations of Mean Deviation in case of Discrete Series: In case of discrete series, mean deviation can be calculated through following steps The first step is to calculate the mean or median or mode of the given series Compute the deviations of the observations of the series from the calculated mean or median or mode. This deviation is also denoted as capital letter D and is always taken as mod value i.e., ignoring the plus or minus sign. Take the summation of the deviations (sum of D) and divide it by number of observations (N). In the same way one can calculate mean deviation from median or mode in case of individual series. Calculations of Mean Deviation in case of discrete series: Mean deviation can be calculated in case of discrete series in a little bit different way. Following are some steps to calculate the average mean when the series is discrete. The first step is to calculate the mean or median or mode of the given series by using the formula as discussed in the previous chapter. Compute the deviations of the observations of the series from the calculated mean or median or mode value. This deviation is also denoted as capital letter D and is always taken as mod value i.e., ignoring the plus or minus sign. Multiply the corresponding frequency with each deviation value i.e., calculate f * D. Similarly, one can calculate the mean deviation or average deviation by taking deviations from median or mode. Calculations of Mean Deviation in case of continuous series: The first step is to calculate the mean or median or mode of the given series by using the formula as discussed in the previous chapter. In the second step, get the mid values of the observations (m) Compute the deviations of the observations of the series from the calculated mean or median or mode value. This deviation is also denoted as capital letter D = m mean or median or mode and is always taken as mod value i.e., ignoring the plus or minus sign. Multiply the corresponding frequency with each deviation value i.e., calculate f * D. Take the summation i.e., (sum of D) and divide it by number of observations (N). The formula may be Advantages of mean deviation: The computation process of mean deviation is based on all the observations of the series. The value of mean deviation is less affected by the extreme items. These are three alternatives available with the researcher while calculating the mean. One can consider the mean or median or mode. Hence it is more flexible in calculation. Disadvantages of mean deviation: The practical usefulness of mean deviation is very less. Mean deviation is not having enough scope for further mathematical calculations. Mod values are considered while calculating the mean deviation. It is criticized by some experts as illogical and unsound. THE STANDARD DEVIATION: Standard deviation or other wise called as root mean square deviation is the most important and widely used measure of variation. It measures the absolute variation of a distribution. It is the right measure that highlights the spread of the observation over and around the mean value. The greater the rate of variation of observations in a series, the greater will be the value of standard deviation. A small value of standard deviation implies a high degree of homogeneity among the observations in the series. If there will be a comparison between two or more standard deviations of two or more series, than it is always advisable to choose that series as ideal one which is having small value of standard deviation. Standard deviation is always measures from the mean or average value of the series. The credit for introducing this concept in the literature goes to Karl Pearson, a famous statistician. It is denoted by the Greek letter (pronounced as sigma) Standard deviation is calculated in following three different series: Standard deviation in case of Individual series Standard deviation in case of Discrete series Standard deviation in case of Continuous series All the above conditions are discussed in detail below. a. Standard deviation in case of individual series: In case of individual series, the value of standard deviation can be calculated by using two methods. Direct method- when deviations are taken from actual mean Short-cut method- when deviations are taken from assumed mean 1. Direct method- when deviations are taken from actual mean: Following are some steps to be followed for calculating the value of standard deviation. The first step is to calculate the actual mean value of the observation In the next column calculate the deviation from each observation i.e., find out () where is the mean of the series. In the next column calculate the square value of the deviations and at the end of the column calculate the sum of the square of the deviations i.e., Divide the total value with the number of observations (N) and than square root of the value. The formula will be . Since the series is having individual observations, some times it so happens that there is no need of taking the deviations. In such a case the researcher can directly calculate the value of the standard deviation. The formula for calculating directly is . 2. Short-cut method- when deviations are taken from assumed mean: In practical uses it so happens that while calculating standard deviation by using the arithmetic mean, the mean value may be in some fractions i.e., .25 etc. This creates the real problem in calculating the value of standard deviation. For this purpose, instead of calculating standard deviation by using the above discussed arithmetic mean methods, researchers generally prefer the method of short-cut which is nothing rather calculation of standard deviation by assuming a mean value. Following are some steps that to be followed for calculating standard deviation in case of assumed mean method: The first step is to assume a value from the X values as mean. This mean value is denoted as A. In the next step deviations are to be calculated from this assumed mean as (X-A) and this value is denoted as D. At the end of the same column, the sum of D () is to be calculated. Calculate the square of each observation of D i.e., calculate. The following formula is to be used to calculate standard deviation of the series. where N is the number of observations in the series. b. Standard deviation in case of discrete series: Discrete series are the series which are having some frequencies or repetitions of observations. In case of a discrete series standard deviation is calculated by using following three methods: when deviations are taken from actual mean when deviations are taken from assumed mean Following are the detailed analysis of the above the two methods. 1. When deviations are taken from actual mean: The steps to calculate standard deviation when deviations are calculated from the actual mean are The first step is to calculate the actual mean value of the observation In the next column calculate the deviation from each observation i.e., find out () where is the mean of the series, this can be denoted as D. In the next column calculate the square value of the deviations and at the end of the column calculate the sum of the square of the deviations i.e., Multiply corresponding frequencies of each observation with the value of D2 in the next column. Divide the total value with the number of observations (N) and than square root of the value. The formula will be 2. When deviations are taken from assumed mean: The steps to calculate standard deviation when deviations are calculated from the actual mean are The first step is to assume a mean value from the observations In the next column calculate the deviation from each observation i.e., find out () where A is the mean of the series, this deviation can be denoted as D. In the next column calculate the square value of the deviations and at the end of the column calculate the sum of the square of the deviations i.e., Multiply corresponding frequencies (f) of each observation with the value of D2 in the next column. Use the following formula to calculate standard deviation c. Standard deviation in case of Continuous series: Standard deviation in case of a continuous series can be calculated by using the following steps Calculate the mid value of the series and denote it as ‘m. Assume any value from the mid values and denote it as A Deviations can be calculated from each series i.e., calculate m – A and than divide it with the class interval value (i) i.e., Multiply the corresponding frequencies of each observation with the deviation value and take the sum at the end of the column i.e., calculate In the next column square the deviation values of each observation i.e., calculate Multiply the value of with its frequencies i.e., calculate Use the following formula to get standard deviation. Properties of standard deviation: As tool of variance, standard deviation is used as a good measure of interpretation of the scatteredness of observation of a series. It is a fact that in a normal distribution approximately 68 per cent of the observations of a series lies less than standard deviation away from the mean, again approximately 95.5 per cent of the items lie less than 2 standard deviation value away from the mean and in the same way 99.7 per cent of the items lie within 3 standard deviations away from the mean. Hence covers 68.27 per cent of the items in a series with normal distribution. covers 95.45 per cent of the items in a series with normal distribution and covers 99.73 per cent of the items in a series with normal distribution. Advantage of Standard Deviation: Following are some advantages of standard deviation as a measure of dispersion This is the highest used technique of dispersion. It is regarded as a very satisfactory measure of the dispersion of a series. It is capable of further mathematical calculations. Algebraic signs are not ignored while measuring the value of standard deviation of a series. It is less affected by the extreme observations of a series. The coefficients make the standard deviation very popular measure of the scatteredness of a series. Disadvantages of standard deviation: The disadvantages are It is not easy to understand the concept easily and quickly. It requires a good exercise to calculate the values of standard deviation. It gives more weight to observations which are away from the arithmetic mean. THE COEFFICIENT OF VARIATION: Another useful statistical tool for measuring dispersion of a series is coefficient of variation. The coefficient of variation is the relative measure of standard deviation which is an absolute measure of dispersion. This tool of dispersion is mostly used in case of comparing the variability two or more series of observation. While comparing, that series for which the value of the coefficient of variation is greater is said to be more variable (i.e., the observations of the series are less consistent, less uniform, less stable or less homogeneous). Hence it is always advisable to choose that series which is having less value of coefficient of variation. The value of coefficient is less implies more consistent, more uniform, more stable and of course more homogeneous. The value of coefficient of variation is always measured by using the value of standard deviation and its relative arithmetic mean. It is denoted as C.V., and is measured by using simple formula as discussed below: In practical field, researchers generally prefer to use standard deviation as a tool to measure the dispersion than that of coefficient of variance because of a numbers of reasons (researchers are advised to refer any standard statistics book to know more on coefficient of variance and its usefulness). GINI COEFFICIENT AND THE LORENZ CURVE: An illuminating manner of viewing the Gini coefficient is in terms of the Lorenz curve due to Lorenz (1905). It is generally defined on the basis of the Lorenz curve. It is popularly known as the Lorenz ratio. The most common definition of the Gini coefficient is in terms of the Lorenz diagram is the ratio of the area between the Lorenz curve and the line of equality, to the area of the triangle OBD below this line (figure-1). The Gini coefficient varies between the limits of 0 (perfect equality) and 1 (perfect inequality), and the greater the departure of the Lorenz curve from the diagonal, the larger is the value of the Gini coefficient. Various geometrical definitions of Gini coefficient discussed in the literature and useful for different purposes are examined here. CONCLUSIONS: The study of dispersion will enables us to know whether a series is homogeneous (where all the observations remains around the central value) or the observations is heterogeneous (there will be variations in the observations around the central value Hence it can be said that a measure of dispersion describes the spread or scattering of the individual values of a series around its central value. For this there are a numbers of methods to determine the variations as discussed in this chapter. But it is always confusing among the researchers that which method is the best among the different techniques that we have discussed? The answer to this question is very simple and says that no single average can be considered as best for all types of data series. The most important factors are the type of data available and the purpose of investigation. Critiques suggest that if a series is having more extreme values than standard deviation as technique is to be avoided. On the other hand in case of more skewed observations standard deviation may be used but mean deviation needs to be avoided where as if the series is having more gaps between two observations than quartile deviation is not an appropriate measure to be used. Similarly, standard deviation is the best technique for any purpose of data. SUMMARY: The study of dispersion will enables us to know whether a series is homogeneous (where all the observations remains around the central value) or the observations is heterogeneous (there will be variations in the observations around the central value). Dispersion when measured on basis of the difference between two extreme values selected from a series of data. The two well known measures are (i) The Range and (ii) The Inter-quartile Range. Dispersion when measured on basis of average deviation from some measure of central tendency. The well known measures are (i) The Mean/average deviation, (ii) The Standard Deviation, (iii) The Coefficient of variation and (iv) The Gini coefficient and the Lorenz curve The range is defined as the difference between the highest value and the lowest value of the series. Range as a measure of variation is having limited applicability. The inter-quartile range measures approximately how far from the median one must go on either side before it can be include one-half the values of the data set. Mean/average deviation is the arithmetic mean of the difference of a series computed from any measure of central tendency i.e., either deviation from mean or median or mode. The absolute values of each observation are calculated. A small value of standard deviation implies a high degree of homogeneity among the observations in the series. If there will be a comparison between two or more standard deviations of two or more series, than it is always advisable to choose that series as ideal one which is having small value of standard deviation. Standard deviation is always measures from the mean or average value of the series. The coefficient of variation is the relative measure of standard deviation which is an absolute measure of dispersion. This tool of dispersion is mostly used in case of comparing the variability two or more series of observation. The most common definition of the Gini coefficient is in terms of the Lorenz diagram is the ratio of the area between the Lorenz curve and the line of equality, to the area of the triangle below the equality line.

The Causes and Effects of Smoking Essay -- Health Smoking Nicotine Tob

The Causes and Effects of Smoking Scientists and health officials have been arguing the detrimental effects smoking has on our health for many years. Smoking can lead to serious complications including asthma, pancreas, lung and stomach cancer due to the large number of carcinogens (cancer causing chemicals) and other various substances added to it. It is a health hazard for both smokers and non-smokers and it is especially harmful to unborn babies. Although smokers claim that it helps them to relax and release stress, the negative aspects of the habit take over the positive. As it has been stressed by the scientists and experts, there are some very severe reasons of smoking but its crucial consequences should also be taken into consideration. There are many causes which make people smoke, however it can be divided into two main causes: physical and psychological. First cause which is physical concerns the human body’s needs. Nicotine contained in cigarette is an addictive substance. It is the chemical which causes addiction. Nicotine reduces tension in the muscles and allows smokers to relax so they feel that they can relieve stress by smoking. Nicotine can also have a calming effect on people who are anxious and worried. This is why it can bring a feeling of tranquility and help smokers to cope with stress. Thus, people smoke when they are depressed, lonely or bored. Nicotine is absorbed by the smoker’s lung and intestines. Very quickly, nicotine can stimulate brain and certain types of nerves so heart rate and blood pressure go up; respiration increases. A little nicotine makes smokers feel more energy and improve concentration. As a consequence, these physical effects created by smoking play an important role in making people feel the need to smoke. Second main cause of smoking is psychological which seems to be a very important factor for people to get the habit. One of the psychological situations which drive people to smoke is low self esteem. Low self esteem is linked not only to smoking but also other behavioral problems such as drinking. It leads to feeling like a dependent individual who can not make decisions for himself or herself and just follow the crowd. So one conclusion to be drawn from this aspect is that people with low self esteem tend to smoke by imitating the people that they see around themselves especially in public place... ... blood pressure, diabetes, high cholesterol levels or excessive body weight. One last very severe effect of smoking is teeth decay. The reason for teeth decay is tobacco products which damage your gum tissue by affecting the attachment of bone and soft tissue to your teeth. An example of the effect is receding gums. A receding gum line exposes the tooth roots and increases your risk of developing a sensitivity to hot and cold, or tooth decay in these unprotected areas. Additionally, smoking can also contribute to bad breath, stains in the teeth and a build-up of tartar on the teeth. Consequently, tobacco which contains many harmful chemicals damages human beings’ health day by day. Although people are aware of the bad effects of smoking, they still smoke for one reason or another. When the current situation is considered, it is clear that smoking which has been spreading all over the world is not only the problem of a country or a territory but the problem of mankind because smoking brings many disadvantages for humans like diseases. I personally believe that it is important to help children remain lifelong non-smokers because they are our hope for a non-smoking future.

Comparing the Voice of Frost in Mending Wall, After Apple-Picking, and

The Voice of Frost in Mending Wall, After Apple-Picking, and The Wood-Pile    The "persona" narratives from the book - "Mending Wall," "After Apple-Picking," and "The Wood-Pile" - also strive for inclusiveness although they are spoken throughout by a voice we are tempted to call "Frost." This voice has no particular back-country identity, nor is it obsessed or limited in its point of view; it seems rather to be exploring nature, other people, ideas, ways of saying things, for the sheer entertainment they can provide. Unlike poems such as "Home Burial" and "A Servant to Servants," which are inclined toward the tragic or the pathetic, nothing "terrible" happens in the personal narratives, nor does some ominous secret lie behind them. In "The Wood-Pile," for example, almost nothing happens at all; its story, its achieved idea or wisdom, the whole air with which it carries itself, is quite unmemorable. A man out walking in a frozen swamp decides to turn back, then decides instead to go farther and see what will happen. He notes a bird in front of him and spends so me time musing on what the bird must be thinking, then sees it settle behind a pile of wood. The pile is described so as to bring out the fact that it has been around for some time. With a reflection about whoever it was who left it there, "far from a useful fireplace," the poem concludes. And the reader looks up from the text, wonders if he has missed something, perhaps goes back and reads it again to see if he can catch some meaning which has eluded him. But "The Wood-Pile" remains stubbornly unyielding to any attempt at ransacking it for a meaning not evidently on the surface. This surface is a busy one, as when the speaker meets the bird: A small bird flew be... ...essing it, when he has no audience to be bullied or flattered, when he is free, and speech takes one form and no other." Despite the presence of back-country characters and scenes in this "book of people," it is as a book of sentence sounds that it most truly exists, as a triumphant vindication of the poetic theory Frost had designed, and as a monument to how much could be accomplished by trusting to the rendering of speech. At the end of "Home Burial," the wife lashes out at her husband in exasperation: "You - oh, you think the talk is all . . ." But for the composer of these poems, the talk is all, whether that of his imagined characters or of himself speaking aloud. Works Cited Frost, Robert. "Mending Wall."
