Does Herodotus believe in Cultural Relativism Essay Example for Free

Does Herodotus believe in Cultural Relativism Essay For its time and place, The Histories of Herodotus is a work of remarkably expansive scope. To set the stage for the wars between Greece and Persia ( 490-479 B. C. ), Herodotus describes the geographical and cultural background and reviews the political history of Lydia, Media, Babylon, Egypt, Persia, Scythia, Libya, Ionia, and various Greek city-states in Asia Minor, on the Aegean islands, and on the European mainland. To record the results of his research (historie, in Greek) with the greatest vigor and accuracy, Herodotus traveled to many of these places and gathered firsthand data from native informants. For this type of research, in the words of a modern commentator, Herodotus merits the title not only of the father of history; he is also the father of comparative anthropology. Among the various classes of information which Herodotus seems to have emphasized, thus suggesting a pattern for later descriptions, were marriage customs, religious rites, burial practices, and food habits. The description of these four categories of traits, or social institutions, were not necessarily executed in the round for every tribe that happened to stroll across the pages of the Histories; but they were mentioned often enough to indicate the direction taken by his curiosity, and the content of the questions he probably put to informants. Herodotus, the ancient Greek, was a cheerful, inquisitive, rationalistic extrovert who traveled over his world to discover the facts, who took delight in telling a good story but usually avoided the temptation to wander very far from sober common sense. His cultural relativism is well known and much discussed, but it is particularly noteworthy that Greeks and barbarians are placed on a equal footing at the outset. Distinctions between Greek and non-Greek break down as the work progresses: the first barbarian for whom we get any detailed information is the Hellenized Lydian king, Croesus; the divisions of lands customary among the Greeks that separate Greek and non-Greek peoples are purely arbitrary; we learn of the Phoenician descent of Spartas kings; and Herodotus states that the descendants of Perseus came to be counted as Greeks. The key dichotomy is not the Hellenic-barbarian bipolarity, but rather the opposition of the ordered society based on law and the arbitrary rule of the despot. But political and social institutions are fragile structures, and Herodotus gives no guarantee that the Greek superiority at the time of the Persian Wars, which was based upon those institutions, will last. In fact his work closes on an ominous note that appears to warn imperial Athens that it is in danger of becoming, if it has not already become, the barbarian. We are presented with the gruesome picture of the crucifixion of the Persian satrap Artayctes at the command of the Athenian commander Xanthippus, father of Pericles, and a piece of wisdom from the Persian founding father, Cyrus, on the dangers of success and affluence. And it is well to remember that Herodotus wrote long after the Persian threat had passed, when Athenian imperial power was at its apogee. Herodotos interest in reciprocity is symptomatic of contemporary philosophy, not least in Ionia. Moreover, Herodotos very project, his attempt to explain and explore the Persian Wars, can be considered as a study of reciprocity in cross-cultural interaction, not least because those wars were for Herodotos a stage in a reciprocal, cross-cultural process, as he asserts in the proem. Indeed, war itself may be seen as an exchange, a reciprocal undertaking: the tactics of the Skythian Idanthyrsos allow him to wage war while explicitly rejecting the relationship that war usually entails. Herodotos origins in western Asia Minor, a key area of interface between Greek and non-Greek culture, may have led him to give particular thought to the issue of cross-cultural reciprocity, as also to the Persian Wars, for which the Ionian Revolt had been the catalyst, if not the cause. At the same time, the justice and injustice of imperialism remained a burning issue through the fifth century into the fourth, and not only Persian imperialism, but also Athenian, Spartan, and Macedonian. The Persian Wars were the great antecedents of the Peloponnesian War, in the early years of which Herodotos seems to have completed his work. The Persians themselves continued to play a major role in the politics of the Greek world: the onset of the Peloponnesian War seems to have inspired new attempts to deal with them, and with other non-Greeks, as indicated in comic style in Aristophanes Akharnians of 425 BC. 25 This is understandable, for it was to be Persian resources that would give ultimate victory to the Spartans in that war. Thus, it is quite possible that crosscultural reciprocity was a topical concern in Athens and elsewhere when Herodotos completed his work, though the issue had been close to the centre of Greek preoccupations at least since the time of the Persian Wars, Herodotos subject. The Persian Wars had reinforced a Hellenic self-image, defined by contrast with the barbarian identity, and had thereby further problematized relationships between Greek and non-Greek. In particular, Greeks (especially Athenians, perhaps) could and did use their defeat of Persia as confirmation of a broader superiority over the barbarian. In exploring the difficulties of forming relationships with the other, Herodotos Histories present readers with failures and disasters, arising primarily from ignorance, over-confidence, and cultural chauvinism. There is a definite element of pessimism in the Histories, for the inability to penetrate beyond contingent nomoi and thereby to see other as self is taken to be an observable feature of human nature, as manifested throughout the narrative. In particular, wars are seen to be the products of injustice and attendant ignorance. But there is also hope; for the author claims for himself the ability to rise above commonplace failings and offers to provide his readers with a better understanding of themselves, of others, and of reciprocity. Like Kroisos, the reader may pass into a state of deeper understanding through advice confirmed by experience. Where Kroisos had the advice of Solon and suffered personal disaster, the reader has the advice of Herodotos the author and suffers vicarious disaster, experiencing experiences. Baldry notices that Herodotos calls into question the whole dichotomy between Greek and barbarian, when he presents the Egyptian perspective, according to which barbarians are not those who do not speak Greek, but those who do not speak Egyptian. At the same time, as Laurot has shown, Herodotos displays no interest in condemning barbarians as such, nor in subordinating them to Greeks. Rather, his presentation in the Histories of nomoi of the barbarian other offers insights into the nomoi of the Greek self (or better, selves), insofar as the various Greek nomoi constitute Herodotos principal frame of reference and benchmark. However, as Rosellini and Said valuably stress, Herodotos does not present the barbarian other as a monolithic unity, any more than he presents the Greeks themselves as a unity: rather he ranges across the different nomoi that exist among barbarians and through the complexities of interaction between various barbarian peoples. The Histories are not so much a mirror, as Hartog would have it, but a hall of mirrors with multiple reflections. The key point is that in the Histories cultural differences, however profound they may be, are presented as secondary to a common human nature and a common human condition: in that sense too Greek is barbarian, self is other. The categories of Greek and barbarian are familiar to Herodotos, but on his view, as the proem indicates, they need not entail the subordination of the barbarian, whose achievements are to be celebrated also. For Herodotos, it is humanness that is the natural identity and the group identity that matters, and man-made variations are merely contingent, for all their exotic character and interest. Confirmation of such a view of Herodotos may be found in the condemnatory response of Plutarch, for whom Herodotos is far too positive about barbarians. The ferocity of Plutarchs response (indeed, his very decision to write a response at all) further indicates the strength of the challenge that Herodotos case presented to the smug asseverations of Greek specialness that seem to have developed through the fifth century and which Plutarch in his day assumed to be right and proper. Cross-cultural interaction was central to Herodotos project in the Histories. At the same time, the problematic nature of reciprocity the uncertainty that arises from its under-negotiation is particularly apparent in interaction across cultures. Indeed, Herodotos concern with the problematics of reciprocity as a phenomenon can be seen as intimately bound up with his concern with cross-cultural interaction. Of course, Herodotos starting-point is a matter of mere speculation. But we can and should observe the organic relationship between cross-cultural interaction, crosscultural reciprocity, and the problematics of reciprocity as a phenomenon. It is precisely within the problematics of cross-cultural reciprocity that the appreciation of cultural relativism is particularly necessary. Therefore, if we move from the claim, already mentioned, that there is a strong sense in which the Histories are about reciprocity to ask why Herodotos should be so interested in the phenomenon, I would suggest that an answer is to be found not in the topicality of reciprocity as a theme in the later fifth century, but in the rationale of Herodotos very undertaking. A broadlybased treatment of the Persian Wars by its very nature invites a simultaneous and inherent treatment of reciprocity as a phenomenon. To examine societies is to explore forms of reciprocities. All the more so, when societies invite comparisons through their It also seems clear that Herodotus approached the task of describing manners and customs with a fairly definite idea of what constituted a culture, and a fairly specific set of questions for evoking details from informants. The criteria which separated one group from another and gave individuality to his descriptive portraits were common descent, common language, common religion, and the observance of like manners in the smaller details of living, such as dress, diet, and dwellings. The Argippeans, who lived at the foot of the Ural Mountains, were presented vividly as being bald from birth, speaking a language of their own, using no weapons, dispensing justice in the quarrels of their neighbors, and dressing after the manner of the Scythians. They lived on the juice of a species of cherry, making the lees into a solid cake which they ate instead of meat. They dwell each man, he said, under a tree, covering it in winter with a white felt cloth, but using no felt in summer. For each group, in other words, seven categories of cultural fact are given. We are told their geographical location and something of their environment. We are told of their language, their dress, their food, their dwellings, their form of self-defense, or their lack of it, their prestige as judges among other peoples. On the other hand, concerning Egypt, one of the more important culture areas, Herodotus says at the outset that he will have to extend his remarks to some length. This countryits climate, its people and animalswas a constant surprise and challenge to the observer, very much as Japan with its customs and Australia with its fauna have challenged the modern traveller. For the Egyptians the number of cultural categories evoked far exceeds the seven used in describing the Argippeans. As for history, Bodins belief in its power to confer knowledge concerning the ways of mankind was unfaltering; and much of both the Methodus and the Republique is devoted to the assemblage of documentation to support this contention. Never before perhaps had a writer on politics or ethnography amassed so large a body of dated materials or laid so large a literature under tribute. He was well-read, not only in the law and the Bible, but in the Talmud and the Cabala; in the ancients, including Herodotus, Strabo, Cicero, Tacitus, and Caesar; in the modern historians, such as Joinville, Froissart, Monstrelet, Commines; and in the travelers, Marco Polo, Leo Africanus, and Las Casas. As they err, said he, who study the maps of regions before they have learned accurately the relation of the whole universe and the separate parts to each other and to the whole, so they are not less mistaken who think they can understand particular histories before they have judged the order and sequence of universal history and of all times, set forth as it were in a table.

Mental Retardation Essay -- Papers

Mental Retardation Mental retardation is defined as, an individual with limitations in cognitive ability and adaptive behaviors that interfere with learning. Individuals with mental retardation learn at a slower pace, have low IQs, and may reach a level where learning stops. There are no exact causes for mental retardation but some things are associated with the disability. Prenatal development problems, childbirth difficulties, and a childhood brain injury can all lead to mental retardation. An individual with mental retardation might have problems in learning and social skills. Learning problems can include: difficulty making decisions, short attention spans, and limited strategies for dealing with changes. Problems they face with social skills are being to friendly, difficulty labeling emotions, and being wary of new places. Despite the setbacks and individual with mental retardation can receive an education and lead a productive role in society. "I Am Sam" is about a mentally retarded man named Sam (Sean Penn). In...

An AP prompt essay discussing how writers must prepare to be unsatisfied Essay

Everyday more and more people try to make a profession in being a successful writer. In this passage, aspiring writer Melusina Fay Peirce writes to novelist Marian Evans Lewes asking if beginning writing at thirty is too old. Evans is moved by this letter and responds mentioning thirty is not too old. In the letter, she comments that even an accomplished writer such as herself is rarely satisfied with hours of work. It is impossible to be an accomplished writer without having years of wisdom behind you. Throughout the passage, she utilizes various persuasive techniques such as refutation and analogies in order to depict novice work as tasteless. In Lewes response to Peirce, she incorporates many rhetorical strategies in order to convey that writers must prepare to be unsatisfied and must not be concerned about flattery because success in writing comes only with maturity. In the beginning of the letter, Evans uses a plethora of rhetorical strategies which suggest that in order to be a writer one must be ready to be unsatisfied. Evans declares her â€Å"consciousness is not of the triumphant kind†. Beginning her letter with a refutation immediately conveys that being a writer is a difficult life. Although one may put hours of hard work into a novel, satisfaction is not always achieved. She then states that â€Å"Exultation is a dream before achievement and rarely comes after†. Evans suggests that she often fancies admiration before her work is finished only to encounter a deficiency of praise after. While Lewes may be a praised writer, she shocks Peirce when saying she is rarely commended for her work; writers’ dreams are seldom met. When encountering the lack of the praise writers such as Evans tend to feel like a â€Å"poor husk†. Evans uses this word to convey the emptiness in which she feels after writing. One always feels like it is possible to create better work but doesn’t know where to look. She then continues on and inquire to Peirce â€Å"Does these seem melancholy? ‘. This rhetorical question implies that these feelings of â€Å"incompleteness† and emptiness are far less melancholy than self-flattery. This connects to the refutation at the beginning of the paragraph stating that writers seldom feel triumphant. Using the various strategies, Evans conveys that to be a writer one must not be concerned about flattery and must be prepared to be unfulfilled. In the next paragraph, Evans refutes Peirce’s main concern of being too old to start writing by giving support to the idea that success come with maturity. Lewes responds by mentioning â€Å"not to fancy yourself old because you are thirty, or to regret you have not written anything†. This refutation replies to Peirce’s concern that she is too old and tells Peirce not to worry. She then states that it does not even matter if one hasn’t written anything prior to being an established writer. Lewes then mentions that the writing of a young writer is â€Å"no better than trashy, unripe fruit†. The underdeveloped fruit mirrors the underdeveloped minds and writing of the young writers. He then states that there is nothing worse than a writer who has â€Å"exhausted himself†. One cannot burn out writing all of their material while young. A successful writer needs to be patient, as triumph in literature comes with experience in everyday life. Towards the end of the letter, Evans reflects that when she was young â€Å"she began a sort of writing which had no great glory belonging to it, but which she felt certain she could do faithfully and well†. This anecdote also works as an emotional appeal as it sympathizes with Peircr, implying mutual feelings both writers felt while young. Evans suggests that mature and older writers are more patient in their writing, consequently producing better works. Evans is very persuasive in her position which states achievements in writings will come along with maturity. In Lewes’s letter to Peirce, she includes numerous persuasive techniques in order to convey that writers must prepare to be unsatisfied and must not be concerned about flattery because success in writing only comes with maturity. Evans’s main point is that one is never too old to begin writing. An aspiring writer shouldn’t hold back on account that they haven’t produced descent works in the past. Wisdom, compassion and insight all come with years of aging and are needed to produce successful writing.

Using Experiments To Identify An Unknown Compound Environmental Sciences Essay

Abstract. The intent of this experiment was to place the unknown compound. The trials that were done to find the individuality of the compound include qualitative solubility trials, quantitative solubility trials, mensurating solution conduction, anion and cation trial, fire trial, and formation of precipitate. It was found that the compound had no odor, was soluble in H2O, and non soluble in methylbenzene and propanone. The ions dissociated in the H2O, making conduction. When the ammonium hydroxide trial was performed no ammonium hydroxide odor was produced. The flame trial yielded a colour that matched that of Na hydrogen carbonate indicating that the unknown compound contained Na. The anion trial for chloride proved to be positive, ensuing in the summing up that the unknown compound was sodium chloride.IntroductionThe group is employed by an Environmental Protection Agency to indentify a compound in the landfill in your place town. The group must besides detect as many chemical an d physical belongingss of the compound as we can. We need to invent two syntheses of the compound, and compare them for cost effectivity, safety, and possible output of the compound. To place the compound, the physical belongingss ( odor, colour, and province ) demand to be established. Next, the qualitative solubility of the compound was tested in H2O, methylbenzene, and propanone, which would find whether the compound would fade out from rain H2O or other chemicals that may be present in the landfill and make overflow. Conductivity was besides tested with a voltmeter in order to find whether or non the compound would be unsafe when dissolved in H2O. If the compound was conductive it would fade out in H2O and produce an electric current. The flame trial was performed to stipulate one of the elements. A solution of H2O and the component was used to put the nichrome wire in, and so the nichrome wire is placed into the fire. If the fire produces a colour it is declarative of a certain metalloid ion or metal. A colour is produced in the fire when the heat of the fire changes the metal ions into atoms which so become aroused and bring forth visible radiation that can be seen with the bare oculus. It is besides of import to analyse the presence of certain cations and anions utilizing trials that identify the presence of the anions chloride and sulphate, and the presence of the cation ammonium. The anion trials for chloride and sulfate prove to be positive when a white precipitate signifiers and the ammonium trial proves to be positive when an ammonium odor is produced. After all of the physical and chemical trials were performed, a solution of the unknown compound and a solution of what was deduced to be unknown compound were reacted with an acid ( azotic acid ) , a base ( potassium hydrated oxide ) , silver nitrate, K sulphate, and K nitrate in order to find if they produce the same consequences. Gravimetric filtration was so performed with the known and unknown s ubstance. A precipitate was formed utilizing Ag nitrate, which could so be weighed. After the filtration procedure, the unknown compound was so synthesized to bring forth a per centum output.ConsequencesTable 1 Physical Properties TestColor White State of Matter Solid Olfactory property None Solubility in Water Soluble Conduction 0.35 VsTable 2 Anion TrialsTrials PerformedConsequencesTrial for Chloride White Precipitate Formed Trial for Sulfate No Chemical reaction Trial for Nitrate No Brown Ring Trial for Carbonate Clear Trial for Acetate Clear, OdorlessTable 3 Cation TrialsTrials PerformedChemical reactionConsequencesTrial for Ammonium NH4Cl + NaOH i?

NaCl ( s ) + H2O ( cubic decimeter ) 1.971 2 98.55 %DiscussionFirst, the physical belongingss of the unknown compound were observed and recorded. It was found that the compound was crystalline in construction, a solid, white, with no olfactory property ( Table 1 ) . All of these belongingss suggest that the compound was ionic because ionic compounds do non hold a distinguishable olfactory property and are solid at room temperature because of their high thaw points. The unknown compound was so tested for solubility in H2O, methylbenzene and propanone. The compound was soluble in H2O, bespeaking the compound was a polar or ionic compound, and non soluble in methylbenzene or propanone which eliminates it being polar or nonionic. Therefore, this points to the compound being ionic. After the compound was dissolved in H2O, the conduction was tested with a voltmeter, which produced a electromotive force of 0.35 Vs turn outing that the substance is conductive since it is over 0.1 Vs. This farther proves that the unknown compound was io nic since merely ionic compounds dissociate in H2O and make an electric current. The fire trial was performed to find one of the elements in the compound. Four known compounds, Na hydrogen carbonate, Mg nitrate, Ca sulphate, and K nitrate were put under the fire trial to compare the unknown to. When the unknown compound was put under the fire trial it produced the same colour as Na hydrogen carbonate, bright orange/yellow, bespeaking the presence of Na ( Table 3 ) . The ammonium trial was besides performed to verify that the compound did non incorporate ammonium hydroxide. No odor was produced when the unknown solution and Na hydrated oxide were assorted, and a odor would bespeak the presence of ammonium hydroxide. Therefore, the compound was proven to incorporate Na. When the anion trials for chloride and sulphate were performed, a white precipitate was produced from the chloride trial, bespeaking the presence of chloride while the sulfate reaction created no precipitate bespeaking the absence of sulphate ( Table 2 ) . In add-on, the unknown compound was put through a series of reactions along with what was believed to be the compound in order to compare the reactions to find if they produce the same reactions. First Na chloride, what is believed to be the unknown compound, and the unknown compound were reacted with Ag nitrate, which produced a precipitate because it was a dual supplanting that produced AgCl which is non soluble in H2O. Sodium chloride and the unknown compound were reacted with K sulphate but produced no reaction because the merchandises sodium sulphate and K chloride are both soluble in H2O. Sodium chloride and the unknown compound were so besides reacted with K nitrate, making a dual supplanting reaction which produces Na nitrate and K chloride, which are besides both soluble in H2O, hence bring forthing no reaction. When Na chloride and the unknown compound were reacted with an acid, azotic acid, but the presence of the Na chloride did non impact the pH of the azotic acid becaus e it was an ionic compound. When the Na chloride and the unknown compound were reacted with a base, K hydrated oxide, there was besides no reaction or alteration in the pH of the K hydrated oxide because the Na chloride is an ionic compound. Both the Na chloride and the unknown compound produced the same consequences in every reaction further turn outing that they are one in the same ( Table 4 ) . Once it was found that Na chloride and Ag nitrate bring forth a precipitate when reacted, the reaction was used to bring forth a certain sum of precipitate which was so used in hydrometric analysis to see if both the known and unknown compound would bring forth the same sum of precipitate. The reaction that was filtrated was NaCl ( aq ) + AgNO3 ( aq ) – & A ; gt ; AgCl ( s ) + NaO3 ( aq ) . The consequences from the known reaction were 1.77 gms of filter paper and 1.081 gms of precipitate entirely, while the theoretical output was 1.225 gms. The unknown reaction has yet to be found. The per centum output for the reaction was 97.56 % ( Table 5 ) . A synthesis reaction was the concluding trial preformed. The undermentioned chemical reaction occurred: HCl ( aq ) + NaOH ( aq ) i? NaCl ( s ) + H2O ( cubic decimeter ) . Once all of the H2O was evaporated out with the usage of a hot home base, the precipitate was able to be weighed and the per centum output could be calculated. The reaction had a percent output of 98.55 % ( Table 6 ) .DecisionAfter being employed by the Environmental Protection Agency, the group was able to place the compound in the landfill. After all of the trials and reactions were performed, it was found that the unknown compound was sodium chloride. Its solubility in H2O, conduction, and crystalline construction points to the fact that the compound is ionic. The positive fire trial for Na indicates that Na is one of the elements in the compound because it produced a bright orange fire. The positive chloride trial, when a white precipitate was formed, indicates that chloride is the 2nd component in the compound. The unknown compound and Na chloride were put through the same reactions and systematically produced the same consequences, farther indicating that the unknown compound is sodium chloride. The gravitative analysis of the known and unknown substances provided similar consequences, endorsing up that the unknown substance was sodium chloride. The synthesis reaction produced a percent output of 95.05 % .Experimental Procedure:Physical Properties TrialsThe physical province of the unknown compound was observed. This included the province of affair, odor ( utilizing the wafting technique ) , colour, and construction. A little sum of the unknown compound was placed in about 50mL of H2O and stirred to see if it would fade out. The same solution was used for the voltmeter and the conduction was recorded.Anion TrialsChloride Ion TestApproximately 1 milliliter of the unknown solution was placed in a trial tubing and 1 milliliter of 6 M HNO3 was added. After that another 1 milliliter of AgNO3 was added. Whether a white precipitate was formed or non was recorded. If a white precipitate is observed, a chloride ion is present in the solution.Sulfate Ion TestApproximately 1 milliliter of the unknown solution was placed into a trial tubing and 1 milliliter of 6 M HCl was added. After that another 1 milliliter of BaCl2 solution was added to the same trial tubing. Whether or non a white precipitate formed was recorded. If a white precipitate is formed, sulphate is present in the solution.Cation TrialFire TestThe heat from the Bunsen fire was used to cleanse the nichrome wire. A little sum of the unknown compound was placed onto the nichrome wire and held over the fire. The colour of the fire was observed.Ammonium TrialApproximately 1 milliliters of 6 M NaOH was added to 1 milliliter of the unknown compound solution. The pennant technique was used to observe if there was any olfactory property. If the odor of ammonium hydroxide was present, there were ammonium ions nowadays in the solution.Responsiveness TrialsChemical reaction with an AcidA solution with a little sum of unknown compound was assorted in 50 milliliter of H2O and a separate solution of a little sum of ammonium chloride and 50 milliliter of H2O. A little sum of the two solutions were placed in to two separate trial tubings and a little sum of HNO3.Double Displacement Chemical reactionA solution of a little sum of unknown compound was placed into 50 milliliter of H2O and a separate solution incorporating a little sum of Na chloride and 50 milliliter of H2O.

The filter paper was weighed and so wetted with H2O somewhat. The solution incorporating the precipitate was poured onto the filter paper and left until most of the liquid had seeped through. The filter was so removed from the funnel and placed into an oven for 10 proceedingss until the precipitate and paper had wholly dried. The filter paper was so weighed with the precipitate still on top. The weight of the filer paper was subtracted from the new weight to obtain the most accurate consequence. The process was completed three times with the unknown substances and twice with a known substance.Synthesis Chemical reactionApproximately 12.3 milliliters of ammonium hydrated oxide was assorted with 6.2 milliliters of hydrochloric acid in a beaker. The solution was placed on a hot home base ( under a goon ) and allowed to boil until all of the liquid evaporated. The staying precipitate was removed from the beaker and weighed.

Osteoporosis essays

Osteoporosis essays Osteoporosis is a one disease that happens when a persons bones become so thin that they can break easily. A person may develop osteoporosis by the thickness of their bones in their early like as well as their health, diet, and physical activity. As you age your bones naturally thin and cannot be completely stopped, however osteoporosis can be reduced by eating healthy and exercising. It is best for people to start developing these healthy habits in their teen years to reduce their risk of osteoporosis. The symptoms in Osteoporosis include: getting shorter in height, breathing difficulty (because of the ribs/back) having a curved upper back, back pains, and breaking bones. The bones that are most often broken are the small bones in the spine, hip, and wrist. During the first 25 to 30 years of a persons life a new bone is made faster than the existing bone is broken down. Between the next 10 to 20 year the bone is broken done at the same rate the bone is made. Usually in women between the ages 45 and 55 and 45 to 50 of men the bone begins to break down faster than the new bone is made. Women are also at a greater risk for osteoporosis than men because men have a higher bone density than women and also women lose protection against osteoporosis when their bodies stop producing estrogen during the time of menopause. A family history, Smoking, alcohol use, no exercise, thin body, low in calcium, decreasing levels of estrogen, and having certain medical conditions are factors of having a high risk for osteoporosis. Healthy habits help prevent osteoporosis. Young women need to take steps to prevent complications. If a person already has osteoporosis healthy habits can help slow the process. Usually older people do not have enough calcium in their diet and need to take calcium supplements. ...

Research Paper on why Illegal Immigrants should be given full Essay

Research Paper on why Illegal Immigrants should be given full citizenship - Essay Example The countries they choose to move to are mostly advanced technologically, with extensive resources and numerous opportunities (Smith 308). This paper discusses the reasons as to why these illegal immigrants should be granted citizenship in countries where they are aliens. Over the years, illegal immigrants have been crossing borders into foreign countries through various ways most of which are dangerous. Some like from those of the Caribbean origin use tubes or homemade boats to enter the US across the Atlantic Ocean. Others elicit help from smugglers to cross the border, while others go to the extent of packing themselves in shipping containers or trucks. However, not all illegal immigrants enter the country voluntarily. Some are brought into the country through the slave trade as was the case in the 19th century. The number of such immigrants has decreased over the years as the trade became nonexistent. Surprisingly, in recent times this trade has been replaced by sex slave trade. In this trade, women and young girls are smuggled into the country for sex services (Steiner 98). Most of them are approached with false information of a chance of a better future in a foreign land only for them to realize that it was all a lie. Being far away from home, they are vulnerable, and they do not have somewhere they can seek help. Governments in a bid to reduce the number of illegal immigrants in their countries have improved technology and increased security measures at their borders. This has made crossing the border an even harder task. Legislations have also been passed, for example, assisting illegal immigrants is a crime in a country like France. However, this is mainly ignored since most of these immigrants have relatives and families in the country and would help them regardless of what the law states. In the United States, the work regulations clearly state that no illegal immigrant should work in the country. However, some industries like the

Why new cars are better then old cars Research Paper

Why new cars are better then old cars - Research Paper Example This is because of the fact that new cars are far better and cheaper than the old cars. Indian car manufacturer, TATA group recently world’s cheapest passenger car NANO, priced only $ 2000. Even though, prices are coming down, the quality and reliability, safety features, performances, fuel efficiency, comfort levels etc of the current cars are far superior to that of the old cars. This paper briefly analyzes why new cars are better than the old cars. â€Å"Anybody with a car older than three years should be tucking aside $50 a month for repairs and maintenance† (Toups). Old cars cause many problems to the drivers on the road. Occasional engine failures, battery failures, clutch problems, break problems, accelerator problems etc are some of them. The old car owner may force to spend a substantial amount of money for as the repairing cost. On the other hand new cars cause little problems to the driver. The performances of new cars are far better than the old cars. New ca rs were given lot of importance not only to the performance, but also for the safety of the passengers. For example, airbags are one of the safety measures introduced in new cars. Airbags help the passengers to save their life when the car accidents occur. Older cars had no such facility to protect the passenger lives. Airbags will be inflated at the time of accidents and it will shield the passengers from big collisions which can cause severe injuries. Apart from the driver and the front seat passenger, current cars have airbags even for the back seat passengers. The number of air bags has been increased from one to more than 10 at present for some of the advanced cars. Moreover, it is easy for the driver to apply brake smoothly and effectively on new cars compared to the older cars because of the advancements in the braking technologies developed by car manufacturers. â€Å"Today’s automobiles are sophisticated electronically controlled machines† (Erjavec,p.3). Elect ronics has given immense contributions to human life and automobile sector is one area in which electronics brought tremendous changes. Most of the older cars were operated manually by the driver. For example, for raising or lowering the window glasses, the driver forced to put lot of manual efforts in old cars. On the other hand, pressing a switch will help the driver to raise or lower the window glasses in new cars. The fuel tank, dickey etc can also be opened with the help of some switches in the new cars. Global positioning system is another electronically controlled modification in new cars. It helps the drivers to identify routes and locate the places. The computers inside the current cars are even capable of taking the control of the vehicle if the driver accidently sleeps while driving. Moreover, the current car equipments can even measure the alcohol levels in the body of the driver and advice the driver whether to proceed with the driving or not. Such facilities were not t here in the older cars. In short, the reliability of the current cars is far more superior to the older cars. Current cars are more fuel efficient than the older cars. The technology has improved a lot so that some of the current cars give even more than 25miles per gallon (Mpg) of petrol. Most of the older cars were delivering fuel efficiency less than 10 Mpg. Petrol or diesel is necessary for driving a car. However, the availability of petrol or diesel is getting decreased day by day because of the increased usages. Americans faced the effects of oil crisis in the seventies. The energy crisis of the seventies started in October 1973 when OPEC (Organization of Arab Petroleum Exporting Countries) and some other Arab countries declared an oil embargo upon United States in
