The Pantheon Essays - Domes, Pantheon, Rome, Free Essays The Pantheon Introduction I chose to report on the pantheon because Ive seen pictures and I am also very fascinated by all the Roman monuments. I looked all around the internet and libraries. The Pantheon was very hard to find information about. It was very challenging but I found enough information to complete this report. This famous building stands in the business district of Romemuch as it was built some 18 centuries ago. Amazingly, it has withstood the ravages of both the elements and war permitting a firsthand view of a unique product constructed by Roman hands. Now, it is exposed to acid rain and fumes from passing automobiles and overshadowed by buildings of inferior taste; but, with trust in the future, the Pantheon will survive. Unrecognized, the design of this ancient concrete building reveals unparalleled features not encountered in modern design standards. Recent studies reveal several major cracks in the dome, but it still functions unimpaired. This condition will surely excite the curiosity of our structural engineers. The building was built entirely without steel reinforcing rods to resist tensile cracking, so necessary in concrete members, and for this concrete dome with a long span to last centuries is incredible. Today, no engineer would dare build this structure without steel rods! Modern codes of engineering practice would not permit such mischief. No investor with knowledge of concrete design would provide the funding. Additional constraints when attempting to build a structure as large as the Pantheon will be discussed later, but briefly they include the use of inadequate hand tools and unsafe lifting devices. I believe we can learn from this activity. Workers can build from a plan and can successfully use their proven practices only if construction quality controls are maintained. History tells us that the Pantheon is a Greek word meaning to honor all Gods (particularly the Olympian divinities). It is ironic that our building has existed throughout many wars while being dedicated to all Gods; one can readily perceive this to be a temple for our one God. And, the Church has claimed this holy structure as a resting place for its most famous Popes, so we continue to honor its magnificent divinity. The first incarnation of this ancient temple was built by Agrippa, the son-in-law of the Roman Emperor Augustus, about 27 B.C. Today, above the entrance carved in stone are the words M. AGRIPPA L. F. COS. TERTIUM FECIT which is translated, Marcus Agrippa, son of Lucius, in his third consulate, made it. Indeed, it is worth mentioning that Agrippa's engineering talents were used in building the famous Pont de Gard aqueduct in France. As with many cities, tragedy in the form of large fires such as those of 60, 64, 79, 100 and 110 A.D. seemed to strike Rome. Originally, many Roman buildings contained travertine (limestone rock) which easily cracked in fires. The first Pantheon was severely damaged and required replacement except for some parts of the lower porch section and foundation. The Pantheon was rebuilt by the Emperor Hadrian during the period 118 to 128 A.D. (a time given by Ward-Perkins).2 But the Ward-Perkins's period is disputed by, Lugli who said the building was started sometime after 123 A.D. and was finished by Emperor Pius about 140 A.D.3 However, most of the bricks were made and placed in the Pantheon in 123 A.D., a date that the maker stamped on his bricks. This was discovered in 1892 by the French archaeologist, George Chedanne. It appears the construction of the rotunda walls took a period of 4 to 5 years, and the dome required a like period because of its height and the meager tools the Romans used. This long construction period was fortunate as it gave this pozzolan concrete ample time to cure and gain strength. Was the second temple like the first? Yes, the fundamental principle of the old Roman religion required that the temples be rebuilt without changes in original form. Tradition required that the main entrance face north, and thus the whole building was oriented on the north-south axis of the building. A description of its structural features is separated into the configuration, foundation ring, circular walls, and dome to more clearly define various components. How these pieces are unique in view of today's design requirements will be discussed shortly. Body The Pantheon is one of the great spiritual

Rudyard Kiplings Classic Speech on Values in Life

Rudyard Kiplings Classic Speech on Values in Life Both praised and criticized as a popular writer, Rudyard Kipling was a poet, novelist, short-story writer, and notorious imperialist. He is best known today for his novel Kim (1901) and his childrens stories, collected in The Jungle Book (1894), The Second Jungle Book (1895), and the Just So Stories (1902). Values in Life appears in A Book of Words (1928), a volume of Kiplings collected speeches. The address was originally delivered in the fall of 1907 to the students at McGill University in Montreal, Canada. At the end of his talk Kipling says, I have no message to deliver. Consider whether you agree with that observation. Values in Life by Rudyard Kipling 1 According to the ancient and laudable custom of the schools, I, as one of your wandering scholars returned, have been instructed to speak to you. The only penalty youth must pay for its enviable privileges is that of listening to people known, alas, to be older and alleged to be wiser. On such occasions youth feigns an air of polite interest and reverence, while age tries to look virtuous. Which pretences sit uneasily on both of them. 2 On such occasions very little truth is spoken. I will try not to depart from the convention. I will not tell you how the sins of youth are due very largely to its virtues; how its arrogance is very often the result of its innate shyness; how its brutality is the outcome of its natural virginity of spirit. These things are true, but your preceptors might object to such texts without the proper notes and emendations. But I can try to speak to you more or less truthfully on certain matters to which you may give the attention and belief proper to your years. 3 When, to use a detestable phrase, you go out into the battle of life, you will be confronted by an organized conspiracy which will try to make you believe that the world is governed by the idea of wealth for wealths sake, and that all means which lead to the acquisition of that wealth are, if not laudable, at least expedient. Those of you who have fitly imbibed the spirit of our university- and it was not a materialistic university which trained a scholar to take both the Craven and the Ireland in England- will violently resent that thought, but you will live and eat and move and have your being in a world dominated by that thought. Some of you will probably succumb to the poison of it. 4 Now, I do not ask you not to be carried away by the first rush of the great game of life. That is expecting you to be more than human. But I do ask you, after the first heat of the game, that you draw breath and watch your fellows for a while. Sooner or later, you will see some man to whom the idea of wealth as mere wealth does not appeal, whom the methods of amassing that wealth do not interest, and who will not accept money if you offer it to him at a certain price. 5 At first you will be inclined to laugh at this man, and to think that he is not smart in his ideas. I suggest that you watch him closely, for he will presently demonstrate to you that money dominates everybody except the man who does not want money. You may meet that man on your farm, in your village, or in your legislature. But be sure that, whenever or wherever you meet him, as soon as it comes to a direct issue between you, his little finger will be thicker than your loins. You will go in fear of him; he will not go in fear of you. You will do what he wants; he will not do what you want. You will find that you have no weapon in your armory with which you can attack him, no argument with which you can appeal to him. Whatever you gain, he will gain more. 6 I would like you to study that man. I would like you better to be that man, because from the lower point of view it doesnt pay to be obsessed by the desire of wealth for wealths sake. If more wealth is necessary to you, for purposes not your own, use your left hand to acquire it, but keep your right for your proper work in life. If you employ both arms in that game, you will be in danger of stooping, in danger also of losing your soul. But in spite of everything you may succeed, you may be successful, you may acquire enormous wealth. In which case I warn you that you stand in grave danger of being spoken and written of and pointed out as a smart man. And that is one of the most terrible calamities that can overtake a sane, civilized white man in our Empire today. 7 They say youth is the season of hope, ambition, and uplift- that the last word youth needs is an exhortation to be cheerful. Some of you here know- and I remember- that youth can be a season of great depression, despondencies, doubts, and waverings, the worse because they seem to be peculiar to ourselves and incommunicable to our fellows. There is a certain darkness into which the soul of the young man sometimes descends- a horror of desolation, abandonment, and realized worthlessness, which is one of the most real of the hells in which we are compelled to walk. 8 I know of what I speak. This is due to a variety of causes, the chief of which is the egotism of the human animal itself. But I can tell you for your comfort that the chief cure for it is to interest yourself, to lose yourself in some issue not personal to yourself- in another mans trouble or, preferably, another mans joy. But, if the dark hour does not vanish, as sometimes it doesnt, if the black cloud will not lift, as sometimes it will not, let me tell you again for your comfort that there are many liars in the world, but there are no liars like our own sensations. The despair and the horror mean nothing, because there is for you nothing irremediable, nothing ineffaceable, nothing irrecoverable in anything you may have said or thought or done. If, for any reason, you cannot believe or have not been taught to believe in the infinite mercy of Heaven, which has made us all, and will take care we do not go far astray, at least believe that you are not yet sufficiently important to b e taken too seriously by the Powers above us or beneath us. In other words, take anything and everything seriously except yourselves. 9 I regret that I noticed certain signs of irreverent laughter when I alluded to the word smartness. I have no message to deliver, but, if I had a message to deliver to a University which I love, to the young men who have the future of their country to mould, I would say with all the force at my command, Do not be smart. If I were not a doctor of this University with a deep interest in its discipline, and if I did not hold the strongest views on that reprehensible form of amusement known as rushing, I would say that, whenever and wherever you find one of your dear little playmates showing signs of smartness in his work, his talk, or his play, take him tenderly by the hand- by both hands, by the back of the neck if necessary- and lovingly, playfully, but firmly, lead him to a knowledge of higher and more interesting things.

Analytical Report Essay Example | Topics and Well Written Essays - 2000 words

Analytical Report - Essay Example Alexander Malcomson encouraged his own business partners to invest in Henry Ford’s recently established business which was mainly viewed with skeptcism by the public. It was only the efforts of Malcomson that allowed Ford to be registered as a legitimate business. At its first stockholders’ meeting, John Gray was elected as the company’s chairman while Henry Ford took over the vice-presidency. Moreover, the three initial starters of Ford would not long remain friends and partners. Subsequent disagreements led to John Gray resigning his post and Henry Ford taking over as president of the company. While Henry Ford was quite successful in managing the company, the real profits came with the outbreak of World War One. As a pacifist, Henry Ford joined other leaders in Europe in trying to avert the outbreak of war. Even though his efforts were unsuccessful, his reputation as a pacifist served him well when the Allied Powers turned to American car manufacturers for mili tary vehicles for the war. Ford’s phenomenal success would continue right through the First World War, but would start to wane before the Second World War because the company was being run as a personal fiefdom and not a multinational corporation. In addition, Henry Ford did not pay much attention to the needs of customers, but was more interested in building vehicles that were to his tastes. In addition, the great Depression suffered by America in the late 1920s affected Ford. To keep afloat, the Ford Corporation had to implement cutbacks and fire many employees. During the Second World War, Henry Ford would be criticized for allowing the Ford Corporation’s branches in Germany to produce war machinery for the Nazis; even though he also supplied engines for the Allied forces. Moreover, from a business point of view, Ford was merely trying to stop his German plants from being nationalized by Adolph Hitler. Ford suffered from low sales after the Second World War due to n ational economic issues as well as problems caused by internal strife, but still managed to remain afloat. To a great extent, Ford’s survival through the years has also been the result of financial assistance received from the American government during its worst crises. Today, more than a hundred years after the Ford Corporation was launched, it is the second largest manufacturer of automobiles in the world. Ford has been able to maintain its position in spite of issues such as globalization, and aggressive competition. In the early years, American car manufacture was basically the forte of Henry Ford (Geyer, 2011). Ford’s method of mass production was copied by many recognized industries of that era, and was soon also adopted by other industries around the world. Global Overview of Issue The Ford Corporation today has branches in Asia, Europe, Africa, South and Central America, the Middle East, and the Caribbean (Geyer, 2011). When Ford first launched operations outs ide the United States, the newly established foreign branches were only authorized to deal in sales and distributions. The economic integration that was brought by the initial episodes of globalization allowed Ford to be able to produce and distribute vehicles from 108 branches stationed across six continents (Geyer, 2011). Ford's operations in foreign nations

Sex in the media (telecommunication) Essay Example | Topics and Well Written Essays - 1000 words

Sex in the media (telecommunication) - Essay Example The issue is a disturbing yet interesting phenomenon that coincides with the growing media expansion and the sexual sophistication of a younger audience who spend unending hours in front of the television. Probably the most divisive subjects when it comes to the media’s responsibility toward society is its powerful control over teens, who, according to a Neilson Study conducted in 2009, â€Å"spends 104 hours a month watching tv† (US Teens Spend...par 7). â€Å"That the media powerfully shapes teens sexual lives to generally deleterious effect is widely taken for granted by politicians, parents, religious leaders, journalists, and even teens themselves† (Carpenter par 2), and according to a Pew Study, â€Å"75% of the 1,505 adults polled...would like to see tighter enforcement of government rules on broadcast content...† (Facts and TV Statistics par 1). One of the major issues involves teen pregnancy and its relationship to sex on television. While there have been many studies done, no one can seem to agree whether the sexual content on television actually has the negative affect some insist. We and network officials can argue the point forever, however there are many who, working with children every day, see the effects in a very concrete way. One of them is Eileen Hart, in whose opinion it is not only true regarding pregnancy, but believes that as a society we should at minimum expect the educational system to counteract the damage. She suggests it be done through the teaching of rhetorical in English education to prepare students to critically evaluate media messages. She cites television as an especially damaging purveyor of inaccurate sexual images in an environment where â€Å"sensory stimuli [combined] with relaxed, non-critical viewing – strongly correlates with negative teen behaviors that result in teen pregnancy† (Hart 1). Along with how teens assess what they see in the media, most of the visual information

Ethnic Minorities Essay Example for Free

Ethnic Minorities Essay We have no choice over what color were born what we do have is some choice over what we make of our lives once were here. This shows us that she feels the same way as Cassie does in that she thinks that blacks are treated unfairly, but she thinks that we just have to get on with it. From this and throughout the whole book we can see that Mama is a very caring woman, but she does believe that people should take things as they come and get on with their lives, even if it means having to live with the violence and hatred towards the blacks from the whites. The second incident that I am going to write about is in chapter eight where Mama is fired from her job as a teacher. In this episode, Mama is giving a lesson about slavery when Mr Wallace and Mr Granger walk in and say that they, Been hearing bout your teaching, Mary, so as members of the board we thought wed come by and learn something. When they walk in Mama is teaching a lesson in history. The unlucky thing is that she is teaching the history of slavery. She speaks about how cruel slavery is and how the country profited from the slaves who were paid nothing and still not free. Then Mr Granger sees the books that Mama has pasted over and acknowledges that all the things Mama is teaching are not in the books. Mama says that she cannot teach what is in that book because, All that is in that book is not true. After this remark, Mr Granger tells her that she would be better off not teaching if she cannot teach what is in the book. This storyline probably originates from Mildred Taylor herself because as mentioned earlier, she says she used to hate the history of blacks at school because she felt that it was all completely false. I dont think that Mr Granger and Kaleb Wallace would have been so willing to lose a good teacher such as Mary Logan because of her views if she hadnt been black. It shows what the whites thought of the blacks having their own view on things. It also confirms the suspicion that the Whites always thought that they were right and that was the end of it. Because Mama loses her job, it puts an even bigger stress on the Logan family because they have an even smaller income. Papas reaction to the news of Mamas unemployment is, Well get by Plant some more cotton maybe. But well get by. From this I think it means that he was worried but didnt want Mama to feel bad because he also believed in what she had been teaching. During this episode, even Mamas boss Mr Wellever doesnt stick up for her, because he is too petrified to stand up for what he believes. This shows how much power the whites had over the blacks and also that the blacks rights to stand up for themselves and be able to say what they wanted to were completely dismissed because they knew what the consequences would be if they didnt do as the whites told them too. Teaching in the 1930s was very different to teaching now especially in the southern states of America. It used to be illegal for blacks to go to school and there were many illegal black schools taking place in peoples houses. Two other options were to have home schooling, which was quite hard if your parents were not very intelligent or to have education at your local church. In 1866 it became legal in the northern states for blacks to go to school with whites but in the southern states such as Mississippi, where Roll of Thunder, Hear My Cry, is set there were separate schools for blacks and whites. The black schools were over-crowded and poorly equipped compared to the white school. We see this in the book when the black children at Great Faith are handed down books that were in some cases eleven years old and were given to the white children first. The slave trade was authoritatively abolished in 1807, but the Southern states of America continued to trade the slaves illegally. Effects were so bad that stud farms were set up where the most clever/strong humans were used to produce the model slave. In 1861-85, the American Civil War took place where the Northern States of American battled against the Southern states. The North won and finally put an end to the slavery trade in the Southern states. At this time large numbers of blacks left the South and headed for the North knowing that there was not as much poverty and chaos there. Even so, many blacks were left behind. As we see in Roll of Thunder Hear My Cry, slavery was a very big issue. There was a short phase where the blacks and whites tried to make peace with each other but it didnt work and soon the Northern states allowed the south to begin slavery once again. The North didnt help the newly freed slaves to protect their rights and let them have their freedom once again. Before I first began to read Roll of Thunder, Hear My Cry I had no idea how much I would learn about racism. To me that word just meant when people made cruel jokes about blacks, but I didnt realise just how badly the blacks were treated at the beginning of last century and before that. I think that the book is very interesting to read when you have never thought about racism properly before and also very interesting when you already know about these subjects. I think that the incidents I have described definitely describe the persecution of the blacks. After reading Roll of Thunder Hear My Cry, I am undeniably thankful that these sorts of acts do not still go on today and I hope that they never will.

Hero Worship Essay -- essays papers

Hero Worship When asked to conjure up descriptions of a hero or heroism, many people would imagine similar scenes. The firefighters pulling a family from a burning building, a soldier saving his platoon from certain death, rescue workers pulling a stranded mountain climber from a precarious ledge, and the Knights of the Round Table saving a damsel in distress, are all examples of the "common" hero. Many people display heroism in everyday life but are rarely recognized either by their peers or by the media. Heroism can be traced back in time as early as mythology has been present. People of that era felt a need to worship super-beings who could solve their problems. Current examples reflecting that age are evident on television today. Both "Hercules" and "Xena: The Warrior Princess" are ever present to save the peasants from the evil and cunning warlords. Mythological heroes had their deeds exaggerated as the stories were passed by word of mouth from person to person. Storytellers have always felt a need to liven up their stories and as they passed them from generation to generation, the stories continued to grow. Everyone knows what heroism is, but describing it can be difficult. Gallantry, valor, bravery, and courage are all traits normally associated with heroism. For the people who risk or sacrifice their own lives in an acts of selflessness, these words are accurate in describing heroism. Few would dispute that a person who pulls another from a burning flipped-over car ready to explode does show heroism. The news media is always looking for acts of heroism as they make for captivating news. Just recently, a fourth grade boy grabbed the wheel of a school bus after it was involved in an accident. Th... ...? There may be several other terms to call these superstars, but to call them heroes or to describe their actions as showing heroism is ridiculous. They may do other deeds away from the sport that could earn them this distinction, but on the playing field it is hard to imagine them rising to the level of a hero. Heroism is shown in many varied situations. The person who can make a split second decision to save someone is no doubt heroic. What does this say about the person who has time to decide a course of action and willingly helps someone? These types of heroes, the dedicated teacher, foster parents, counselors and a myriad of other examples, may show the most heroism of all by choosing to save a life. It is shameful that we do not recognize these people more often and have these stories told by the media and peers. They may be the greatest heroes of all.

Why was Malthus wrong about Japan?

Today Japan is a highly developed first world country with a vast population and a booming economy. The demographic history of Japan and how it reached this renowned economic status has been the focus of much theorising and has engaged the minds of many demographers, economists and historians for centuries. Japan is unique in the way its population has changed and its economy has developed without the stimulus of overseas markets. It does not boast the best physical landscape, being 85 percent mountainous, and it is not well endowed in terms of resources. Despite these negative attributes however, Japan has developed, and to such an extent it can now boast one of the worlds leading economies. Indeed Japan was the only country outside the western world to have developed at a similar rate. In the 18th century a Swedish doctor, P. Thunberg commented on Japan, ‘Of all the countries that inhabit the three largest parts of the globe, the Japanese deserved to be ranked first, and to be compared with the Europeans. ‘ (Modern Japan, P. Duus. ) It stands to reason therefore that Japan's history merits such a wealth of discussion amongst academics. Part of Japan's success as a country has to be attributed to its longstanding political regime. For centuries Japan was an empire ruled by an emperor based at Kyoto. From the 12th century however Japan was governed by Shogun (military leaders) who oversaw the day-to-day life of the Japanese people. The emperor, in effect, was under house arrest, taking a submissive role being more of a spiritual leader to the people. The year 1600 saw an important event for the political governing of Japan. It was in this year that a battle (Sekigahara) established the supremacy of the Tokugawa family as ruling shoguns. From 1600 to 1868 this family ruled and these 268 years of Japan's history became known as the Tokugawa period. It is this period that is of fascination to many demographers as during this time Japan experienced stagnation in its population but it also seemed to be the onset of its economic success. From the early 18th century to the Meiji restoration in 1868 Japan's population stayed at around 33 million. It is this 150-year period of stagnation that is of interest to studiers of the demographic history of Japan. There is also much discussion as to whether the population as it was, was inextricably linked to economic growth or vice versa. Searches for explanation of population trends date back centuries. One of the earliest and probably the most famous explanation of observed population figures in the world in general, was put forward by the Rev. Thomas R. Malthus in the 18th century. In 1798 Malthus's ‘Essay on Population' was published, in which he wrote at length on past, present and future population trends of mankind. His most famous stance on population levels was that ‘population, when unchecked increases in geometrical ratio; subsistence only in an arithmetical ratio. (Malthusian Population Theory, McCleary. ) He believed that mans (sic) power to produce population is greater than his power to produce subsistence, thus meaning that that the population of a country was constantly held in check by misery and vice. From this a simple model is produced illustrating the point that if populations increases; food prices will increase; real income will decrease; and thus mortality will increase (figure 1. ) The ultimate check according to his works was the want of food, but this was never an immediate check except in the case of actual famines. The constant checks can be classified into two sets, preventative and positive. Positive checks are multifarious and include such components as exposure to the elements, epidemics, war, plagues, famines and extreme poverty. The preventative checks can be further sub-classified into vice and non-vice. According to Malthus however, there is only one preventative check that can be classified as vice and this is moral restraint. The consideration of moral restraint was a latter thought from Malthus, added to his ‘essay' in 1803. From this a more optimistic model of possibility was constructed (Fig 2. ) The two checks vary inversely from one another and can be in operation with varying affect according to the society in which there are operational. The situation as it was in Japan must have had some constituent that caused the observed trends in population. If Malthus's theory is believed to have been operational in Japan then some sort of check was holding the population at its stagnated rate. Japan, unlike Europe at the time was a closed system. Emigration was unheard of and likewise nobody entered the country. Internal migration was also low, although would not have affected population figures. This was mainly due the Tokugawa establishing a period of isolation, cutting Japan off from the rest of the trading world. In terms of Japans population this meant that migration was not responsible for the stagnation, therefore according to Malthus it must be due to high mortality rates and/or moral restraint alone. Malthus travelled to various European countries to study their population trends in order to supplement the work in his first essay. He did not however make it as far as Asia, but did manage to comment on Japan and China in his work. He tended to make generalisations about Japan based on his thoughts about China, believing that in both of these countries moral restraint was not practiced, as it was only adapted to Western Europe. His work led him to believe that in Japan and China marriage was universal and occurred at a very young age. Taking this into account, Malthus attributed positive checks on population to the cause of the stagnation the Tokugawa period. Included in the positive checks Malthus believed occurred in Japan was the act of infanticide or ‘mabiki', literally meaning ‘thinning out. ‘ Again he depicted Japan as being similar to China, but whether he was wrongly casting aspersions about Japan or whether infanticide was one of the components accountable for the population trends is another area that has been widely debated. Many people in this field of work since Malthus have devised various explanations as to the cause of Japans stagnation, and many have been curious as to whether Malthus was right about Japan. In order to deem Malthus right or wrong on this topic information on fertility and mortality levels as well as the marriage system and evidence of infanticide is needed. Early studiers of Japan's history found a way of gathering such information. During the Tokugawa period a registration system, known as Shumon Aratame Cho, was devised (mainly for tax reasons) that recorded births, deaths and other such information for villages in Japan. By studying, what were tantamount to an early form of census, family reconstitution is possible and a better idea of the overall demographic change at that time in Japan is given. Generations of population historians have performed village studies and different generations have varying ideas about the trend in population. The first generation of population historians believed Malthusian checks to be in action in Japan. Subsequent work has questioned this conclusion and many other avenues of thought have been opened up. Levels of fertility are related to marital patterns. This is an area that Malthus had decidedly definite views on in Japan. A control on marriage may have been responsible for the stagnation experienced between 1700 and 1850. This kind of population control may have been conducted in Japan in order to yield positive benefits from lower fertility levels, managed food prices and improved real incomes. Malthus believed that nuptuality in China and Japan was universal and occurred at a young age. He did not believe that controls on marriage could occur in Japan as outside Western Europe h thought that ‘the passion between the sexes is necessary' and cannot be overcome (Malthusian Population Theory, McCleary. From studies of nuptuality records (including components such as age at marrying and proportion of people ever married) it is shown that marriage was universal in Japan but was not at such an early age as it was in China. If nuptuality levels for Japan are compared with England and China for the same time period, then Japan falls somewhere in the middle (see fig 3. ) Universal marrying would suggest high levels of fertility but as discussed this was not the case in Tokugawa Japan. The issue of marrying at a later age can account for low levels of fertility, and possible reduced fecundability in women. Other factors can be attributed to fertility levels and many studies have been carried out in this area. T. C Smith, part of a later generation of population historians, conducted a study of a village which he named ‘Nakahara,' to give an overall general pattern of what was occurring in Japan at this time. Smith looked at fertility levels of the village and constructed fertility curves to examine the possibility of infanticide. The curves showed low levels of fertility, and were convex suggesting that there was an absence of birth control in the village. This adheres loosely to the standard levels of fertility at the time; although the figures in question were lower (fertility levels were naturally low in Tokugawa Japan, lower than pre-industrial Europe. ) Smith believed that the low levels of fertility were due not only to factors such spacing and lactational amenorrhea, as put forward by some of his contemporaries (e. g. Cornell), but also to the practice of infanticide. If Smith's study is consistent with the rest of Japan, then Malthus's theory would be true. However fertility curves alone do not prove beyond doubt that infanticide was occurring. L. Cornell believed the reasons for the low levels of fertility could be explained by factors other than infanticide. She believed the low level of fertility in general in Japan was a result of cultural rather than structural patterns. One of the main reasons put forward for this was the long lactation periods of Japanese mothers. It is biologically proven that the longer the lactation period after birth the harder it is for a couple to conceive their next child. This, Cornell attributes to the observed low fertility levels. Another reason put forward is migration patterns of males in villages at that time, causing a reduction in fecundability. Migration to castle towns, where employment had a large pulling power, was seasonal in villages and as a result of long periods of migration, fecundability decreased and fertility was kept at a low level. Cornell believed that these factors not deliberate controls on family size by the practice of infanticide as other academics believed, caused low levels of fertility in Japan. This was brought about by controls on society by over-riding cultural trends. Smith however, had evidence other than fertility curves to support his claim about infanticide. He studied the sex bias in families in Nakahara to add weight to his argument. He believed that the sex of the next child in a family was enforced by infanticide. Assumptions are easily made that this practice accords with the widely heard of folklore that males were the preferred sex in Japanese households, therefore one would expect the sex ratio to be male biased. However Smith found from his studies that the sex of the next child was not biased to males. He tabulated the evidence, which showed that in a family with predominantly male children, the next child was more likely to be female, and in families that had equal number of male and female children, the next child was most likely to be a male. The opposite was true in families with predominantly female children. However sex selectiveness was not found in other studies, for example in a study by Hayami, there was no evidence of sex selectiveness in families. Smith used this evidence to suggest that infanticide was a means of family limitation in Japan. Another piece evidence he found for the practice of infanticide was that small landholders had fewer children than large landholders, suggesting that family limitation was practiced as a long-term plan, so as to not put financial on the existing family and to maintain living standards. This idea has been rejected however by other authors such as Hanley and Yamamura who believed that infanticide was not only practised by peasants and poor families, but also by the rich who chose to limit their family in order to husband assets. Many authors speculate that infanticide was also practiced to limit the number of male heirs in a family and lessen the competition for family headship. On the matter of infanticide in Japan, contrasting ideas make it difficult to conclude if Malthus was correct in his assumption. However what can be concluded is that villages would have undoubtedly varied in their practices and beliefs. From a persons study of one village it would be wrong to conclude that infanticide was or was not practised in general in Japan. What would be a fair assumption would be to say that infanticide probably was operational in some areas and not in others. However it seems unlikely that infanticide alone, occurring in some areas would lead to the stagnated population that occurred in Japan at this time. Other checks on population must now be looked at to prove or disprove Malthus's theory. It is a given that fertility levels were low in Tokugawa Japan, so according to Malthus mortality must be a contributing factor of the population stagnation. From the Shumon Aratame Cho it is difficult to gain an idea of mortality levels, especially infant mortality. It has been estimated (Cornell) that by as late as 1926 a quarter of all deaths in Japan were infants. In the early Tokugawa period death rates were high and fluctuating. The life expectancy at birth at this time was in the low thirties. Epidemics as a constant check, proposed by Malthus, occurred regularly in Japan; however by about the 16th century the population was large enough to support such disasters. There were also some wide spread famines, particularly bad ones occurring in the 1730's, 1780's and the 1830's, which obviously would have made a dent in population figures. However there is a tendency for populations to recover quickly from famines, and many people would have simply moved away from the area. These two Malthusian checks seem not to have had a large impact on death rates, suggesting Malthus was wrong about Japan in this case in point. Death rates not associated with widespread disasters, must also be take into account. Mortality levels were generally higher in the cities, of which there were about 200 at this time, than in the countryside. An increase in the number of people living in cities could account for a high national mortality level; however improvements in the standard of living meant that death rates actually decreased in these areas. It seems that in this period of Japan's history contrasting factors were at work keeping the death rates at a constant level. Warfare decreased at the beginning of the Tokugawa period, lowering death rates; but epidemics were introduced, increasing the rates. Similarly death rates increased slightly as cities grew, but the improvements of living standards combated this increase. Malthus was correct in the sense that checks on population were occurring in Tokugawa Japan, however he did not account for the fact that Japan with a completely different culture and set of traditions from Europe, would have had different ‘checks' on the population working in opposition to the ones he proposed. A picture is now appearing of life in Tokugawa Japan. Fertility levels were low; mortality levels were high and fluctuating at the start of this period but then decreased towards the end. These two demographic variables can account in part for the population remaining constant for so many years, but it is not exactly in accordance with what Malthus thought about Japan. In reality Japan was much more akin to England in terms of its demography than China. Malthus was wrong in this case as well. He presumed Japan to be dissimilar to European countries and because of its locality in relation to China, to be much more alike it neighbouring country. Malthus had some general thoughts on population, not specific to Japan, but which are also wrong in Japans case. Malthus believed that ‘man (sic) does not like hard work', and this is why subsistence cannot take keep pace with population. This would ultimately lead to a positive check on population, which Malthus did believe was occurring in Japan. From the time of the Tokugawa period to present day, the people of Japan have shown to have been hardworking, which is represented in the level of their economic success today. From the 17th century agriculture was the main employment sector in Japan. During this century agriculture took off at a vast rate and began to keep pace with the growing number of mouths. As the population slowed and productivity continued to increase, the per capita food supply also increased. Small-scale cultivators dominated the agricultural economy in Tokugawa Japan, but this was only the starting point of the economic transitional change in Japan. By the late Tokugawa period, ‘proto-industrialsation', a term referring to the production of goods for distant markets was underway. New technologies spread and output of products such as soy sauce, bean paste and vegetable oil was a substantial proportion of all non-agricultural output. Proto-industialisation was concentrated in rural areas, which meant migration to large cities slowed, which in turn would have affected mortality rates, as mortality was consistently higher in these areas. In this case Malthus was also wrong in his assumptions about Japan. The population did not grow in a geometric ratio whilst the subsistence only grew in an arithmetical ratio. In fact quite the opposite occurred during the Tokugawa period in Japan. Overall it seems Malthus was wrong in most of his assumptions about Japan, such as universally low ages of marriage, moral restraint not being practised and widespread infanticide. However he did touch upon factors that operated in Japan as they did in many other countries at that time, such as family limitation and preventative checks affecting population numbers. In fact given the very little first hand knowledge Malthus actually knew about Japan, the only way his speculations could have been correct would have been purely by chance, which as highlighted is the not the case. Malthus was incorrect in his assumptions about the extent to which population-influencing factors occurred in Japan. Never the less he gave many population historians a foothold to further investigate the demographics of historic Japan.

These ideas were all working together to help achieve HitlerÂÆ'ÂÆ'‚Â ­s plans of conquest. Though it is argued that a lot of these ideas were more of a hindrance, than a help. One of the principle ideas of a fascist state is total control. Hitler used this principle to make the task of achieving all his other goals much easier. "The Reichstag has passed the following law the government is also able to pass laws." In Article two:- " The laws issued by the government shall be issued by the chancellor and published in the official gazette" Later on, another law was passed:- "The sole political party existing in Germany is the National Socialist German WorkersÂÆ'ÂÆ'‚Â ­ Party." By Passing these laws, Hitler stood alone, as the sole dictator of Germany.By doing this, Hitler gained a lot of support, as well as a lot of criticism. But Hitler was able to use this total control to stop most the criticism turning into outright opposition. A lot of this power was filtered throughout society, and numerous changes took place. This Generally translated into the reduction of civil rights the people held. This meant things like unions were outlawed, political opinion was outlawed, freedom of speech was outlawed, freedom of press was outlawed, Hitler needed to gain 50% of the Reichstag to gain power. This meant that he had to appeal to many different groups if he was to gain power. He did this by offering something to almost everyone.

To Do vs. To Make

To Do vs. To Make To Do vs. To Make To Do vs. To Make By Maeve Maddox Pointing out that some languages, like Russian, have only one verb to express the meanings of English make and do, a reader requests a little guidance: Please could you explain the difference between the verbs â€Å"to do† and â€Å"to make.† Is there some kind of formula or method? Would that I could postulate some foolproof rule for knowing when to use do and when to use make. Some general guidelines do exist, but for many of the idioms, memorization is the ESL speaker’s only recourse. Generally speaking, the verb do and its forms are used to talk about duties, jobs, or leisure activities: England expects that every man will do his duty. Who does your hair? He’s doing time for assault. She can’t do enough for that lay-about husband of hers. Jake does the crossword every morning on the train. Have you done your homework? The verb make is used to talk about constructing, creating, or performing something: The company has made an offer on a new building. Excuse me while I make a phone call. The child made a face behind the teacher’s back. The builders are making progress on the house. Time is running out; we must make a decision now. We tried to move without making a noise. It’s possible to use do with an adverb: I hope he will do well there. He did badly in his last job. Make is usually followed by a noun: make the bed make amends make a mistake make a visit make a speech Exceptions are the idioms â€Å"to make nice† (behave in an agreeable manner), and â€Å"to make do† (get along with what one has†): His mother told him to make nice with the neighbor’s children. As we haven’t the money for a new car, we shall have to make do with this one. A great many expressions that are used with make can be rephrased with verbs that correspond to the noun that follows make or with another verb: to make a confession > to confess to make a visit > to visit to make a suggestion > to suggest to make a face > to grimace to make believe > to imagine Want to improve your English in five minutes a day?

Should football managers be sacked when results (on the field) are Essay

Should football managers be sacked when results (on the field) are poor - Essay Example A football manager can have the best players in the world, but without credible managerial skills, less talented players who have a better managing team will beat his team. Each player has their own talents, qualities and strengths that proper workout on a daily basis that is meant to sustain morale, motivation and competence the player’s capabilities will not be portrayed in the games. They will be wasted. The secret to football success is in the backroom stuff and management. The best way to ensure staff competence is by understanding what the different football manager stuff attributes mean for training, transfer handling and scouting- this is what is called the ‘non-play attributes’. The decision to hire or sack a manager implies the consideration of aspects linked to environmental pressures, the importance of experience and skill of the manager and the emotional empathy of the manager with the institution. It is important that the manager be sacked based of f ield performance because just as Tena said, there are other external factors to be considered. These factors include the sponsors, the fans, the stakeholders, and the prestige of the football club among others. If a team keeps losing, then there is pressure from these external attributes on the management to take measures towards the rectification of the problem. These measures may lead to the sacking of the manager and other staff members. ... If a team keeps losing, then there is pressure from these external attributes on the management to take measures towards the rectification of the problem. These measures may lead to the sacking of the manager and other staff members. Apart from external factors, there are internal factors that would lead to the sacking of a manager in football. Paolo Di Canio was sacked from being Sunderland’s manager after a player rebellion where several players refused to play for him again. This made it impossible for him to continue managing the team (The telegraph, 2013:16). For the effective management of a football club, the manager should show certain coaching attributes that he should ensure the players are good. These include; attacking, defending goalkeeping coaching and fitness. The lack of these skills will lead to game loses and so if the manager cannot ensure proper training of the players then he should be sacked. The manager should also have a good mental capability i.e. his ability to observe, and act upon an individual’s state of mind and be able to act accordingly. Apart from this, the manager’s ability to work with the youth should be a contributing factor to how well the team will act in the games. The relationship between the players and the manager needs to be good for there to be effective management and good results. It this relationship is compromised, for example, if the players feel that the management is like a dictatorship, or there is no respect for the management, then the manager will not be effective in his managerial duties, and he should therefore be replaced. These are some of the factors that will lead to poor performance; the manager should be replaced when the team has poor performance because it is a

The Movie Fight Club Review Example | Topics and Well Written Essays - 750 words

The Fight Club - Movie Review Example Although one can argue that the narrator makes more use of his mental capacity as evidenced by his imagining Tyler to the point that he thinks Durden is a real person, in the Narrator’s mind it is still the use of the body thru fighting and having sex which is dominant. Furthermore, this also serves as proof to the disorganized thoughts of the person.An important matter that faces us now is how to make sense of the narrator’s creation of Tyler. Was he trying to project himself as a hero? Deep inside, was he actually a person fond of out-of-the-norm sexual practices? These are questions that must be addressed because these characteristics are for an Eros person and not for Thanatos.For sure, the Narrator made Tyler as a hero who gave meaning to the life of other persons. We argue that this is not the case. Tyler is a separate entity and not the narrator himself. It is not the Narrator consciously projecting himself as the hero.

In the end it leads to regret and what-could-have-been statements. What then could lead to a happy life There many ways in which people can be happy. Some achieve it by adding zeroes to their bank account while some consider the lack of conflict in interpersonal - especially marital- relationships as a happy life. Whatever form it may assume, happiness can be achieved if a person is successful in his endeavor - whether
