Bletchley Park Coursework Essay
1.) What can you learn from Source A about the work of Bletchley Park? From reading through source A, the reader can analyse that the work done in Bletchley Park was kept extremely confidential, due to the fact that when it came to infiltrating enemy intelligence, organisations had a tendency to keep the knowledge within the vicinity. In addition, the cryptologists and mathematicians that worked there had no idea as to what was happening in the consecutive huts because it was so departmentalized. In times when countries were at war, there was an almost obligatory need for secrecy, because one wrong move could determine the fate of either side. Any decoded messages were passed onto the other huts through narrow wooden tunnels that connected them. However, we only have the opinion of one worker within one hut, making it hard to decide whether or not this evidence is unsubstantiated. We do not know whether the government became lenient with the strict rules they implemented, whether it was towards the end of the war or at the middle. 2.) Does the evidence of Source C support the evidence of Sources A and B about the work of Bletchley Park? Explain your answer. In comparison with source C, A and B often convey a sense of perplexion, due to the fact that a significant amount of people werenââ¬â¢t aware of whether war was declared or not. Moreover, you have the continuous notion that people did not know the outcome of their work, or the purpose of the work done within the other huts. In some aspects, what the code breaker in source C has wrote is often similar to what the previous workers also wrote. For example, the source continues to mention the secrecy kept within the huts. Because there was such a crucial need for it, the workers did not know whether their breakthroughs were futile or not, for if the code they cracked had no significant meaning, then it would clearly be a waste of time if they received simultaneous discoveries which were of no value. If they did come across something of importance, it would be for the benefit of the war that they would not be informed, due to the fact that a minority of people would carry out certain acts of espionage. Since they were all written by workers that worked closely within Bletchley Park, I can only say that the sources inevitably have certain similarities, regarding the fact that their work was very covert, and that the groups were all departmentalised. However, the origin of the sources can cause differences between them. Source A was written in Hut 3, where as Source C was written in Hut 6, meaning that Source C may not support Source A after all because of the different locations that they were written in. This evidently causes problems, as the sources are of different origins. Again it is slightly biased, as they may have been recorded at different dates. Who knows whether they implemented a certain level of secrecy within each of the huts, depending on the necessity of the work they would have done. 3.) How useful are Sources D and E in helping you to understand how Bletchley Park was able to crack the Enigma codes? Source E is not exceptionally useful in helping you to understand how the British cracked the enigma code, as it is just a visual source. Nevertheless, you can see that this Machine helped them to interpret the incessant gibberish that they received from the Germans, via wireless stations that they had situated all across Britain. This machine or the ââ¬Å"Enigma Machineâ⬠as it became known was where their mainstream of information was translated from the German ciphers into our dialect. It was a military cipher device, which helped the British purge the seas of enemies that lurked beneath the waters. All it consisted of were 3 reels which had the whole alphabet imprinted on them, and the whole of the alphabet on buttons that you pressed. Yet the Germanââ¬â¢s soon found out that their machine wasnââ¬â¢t as secure as they would have hoped, so they added another reel into it. In order for the cryptologists to translate the German codes, the Enigma machine had to be calibrated with exactly the same settings as the Enigma Machine that had sent the message. Source D simply sheds a negative light on the outcome of their work. Although logically categorising information seems to condense the ciphers that they received, it only made things more laborious as thousands of messages had to be decoded everyday. Pressure would mount as the codes to be cracked accumulated, making the cryptologists and other workers very anxious indeed. As always, there is always a ââ¬Å"butâ⬠. Source D does not give any relevant information in some sense, because that is not where the main work took place. The codes were translated in Hut 3. On translating the ciphers, they would then be sent to Hut 6 to be deciphered. Whatââ¬â¢s more, is that being a visual source, source C does not offer any other information, other than the fact that they used this machine to decipher codes. This was not the only military machine that was used, as a newer version ââ¬Å"Ultraâ⬠succeeded the Enigma Machine. 4.) Use Sources F and G and your own knowledge, to explain the importance of Bletchley Park to the war effort. During World War 2, many people werenââ¬â¢t aware of the audacity of Bletchley Parkââ¬â¢s work towards the war effort, although vague details were described to them which werenââ¬â¢t enough to convince them of the magnitude of their work. However, the Prime Minister of Britain considered it as a great asset to the war. Winston Churchill was unlike his predecessor Neville Chamberlain, for he took a keen interest of the activities and the purpose of Bletchley Park. He considered it as an extremely significant help to the World War 2 effort, as can be seen from Source F, ââ¬Å"Make sure that they have all that they want extreme priority.â⬠He then follows on to say that they must take action this day, which signifies how much he admired their efforts to help facilitate with the English army. One of the beneficial uses of Bletchley Park was that they were able to get direct information of the Germanââ¬â¢s intentions. For example, whether they were planning pre-emptive strikes, or whether they were planning to ambush the British in areas known to them. Because the Germanââ¬â¢s assumed that the Enigma was safe to use, they passed noteworthy information on to people with high rank, even Hitler himself. They were also able to determine whether tips that they had received were bogus or not. Nonetheless, although they were able to get hold of information of some sort, it was sometimes ignored. The reader needs to keep in mind that it was not Bletchley Park that dealt with the physicalityââ¬â¢s of war. In addition to what they knew, they could also form battle plans, and obtain information about reserves, which evidently put the British at some sort of an advantage, because they knew of their enemies attributes. One of the many successes of Bletchley Park was ââ¬Å"Ultraâ⬠, for it provided an immense amount of information for the naval intelligence. It allowed the British to prevent German U-Boatââ¬â¢s from attacking their convoys. This was an extremely major triumph because: Britain was dependant on the convoys from America and Canada; they would often supply raw materials and food and send them through convoys. But with so many German U-Boats hidden within the endless depths of the Atlantic, the possibility of a convoy being sunk was almost inevitable. When the Germanââ¬â¢s introduced the four wheeled enigma ââ¬Å"Sharkâ⬠, the British intelligence lost almost all contact with their enemies U-Boats. The number of convoys sunk in the Atlantic rose rapidly, only until they were able to crack Shark in December 1942. The Germans once again had the advantage in the treacherous Atlantic. With the unravelling of Shark, the British were once again able to locate the positions of German U-Boats, which then led onto the success of the Battle of the Atlantic. 5.) Study all the Sources. The writer of Source I believed that Bletchley Park had a very great impact on the outcome of the Second World War. Use the sources and your own knowledge to explain whether you agree with this view. Bletchley Park, which was otherwise known as Station X had indeed a great impact perhaps not on the outcome of the war, but certainly on the progress of World War II itself. Although some historians would argue that Bletchley Park did not help Britain emerge victorious at the end of the war, they cannot deny that it was beneficial to the progress of the war, other than the outcome. From looking at Sources A to D, one can analyse that the work the cryptologists did wasnââ¬â¢t just a mere triviality of every day life. Its significance is perhaps not expressed as it should have been in the sources, but the workers obligation to maintain secrecy within their huts says enough. If their superiors did not uphold the need for secrecy, then perhaps the war would not have turned out as it has today, for espionage in such a reckless place would certainly be expected. In addition, the Prime Minister Winston Churchill took such a keen interest in Bletchley Park, that it was hard for individuals not to consider its work extremely valuable towards the war effort. The role of Prime Minister is considered very influential in Britain, and a position which grants its occupant a great deal of power. Hence this shows that because Churchill was importuned with such a grievous burden (leading Britain through World War II), the thing that he perceived to be a solution for the ominous U-Boats was Bletchley Park. In fact, it was partly because of them, that the number of German U-Boats diminished, during the battles fought at sea. The writer of Source I believed that Bletchley Park had a huge impact on the outcome of World War II, but to what extent? The many codes that Bletchley Park used to crack German codes, is supposedly the very reason why they were renowned for shortening the war. Due to the fact that they were able to crack German codes that they had intercepted by using codes such as ââ¬Å"Ultraâ⬠or ââ¬Å"Sharkâ⬠, it allowed them to pin-point the location of German U-Boats, which were dealing severe blows to the convoys that were to export goods to Britain. Once they were able to translate German naval codes with ââ¬Å"Dolphinâ⬠, destroying U-Boats during the Battle of the Atlantic became uncomplicated. And tonnes of shipping were saved from being sunk. However, once the U-Boats were withdrawn from the Atlantic, they began to pose a new threat in the Mediterranean. The British enjoyed a considerable amount of ease during the battles that they fought in North Africa, until the German U-Boats arrived. But once again, the British intelligence was able to crack the code permanently, which enabled them to fight back the German and Italian forces. Yet it was not always to their advantage for at times, they werenââ¬â¢t able to crack the codes fast enough. Perchance when they did, the translation would have no significance because of efforts made to crack it. By the time machines such as Bombe or Colossus were made, they would already have suffered from needless losses, which would have been prevented, if time were in their favour. This is indeed what happened in North Africa, for the messages that the Americans sent to the British were intercepted, and those that the Y Service received would be cracked a week after the Germans had transmitted them. Of course, the British obviously had other advantages over the German other than destroying their U-Boats. Because the Y Service was able to intercept messages of many origins, they were able to acquire information which they could then relate to their army. For instance, they could set up battle plans and formation tactics for the army, consequently helping them to succeed in battle. The messages that they intercepted would often lead into the army being aware of the Germans moves, for the reason that some messages were sent to the German general, or someone with a similar position. Information about their reserves was acquired, which meant that the English army new what they were up against, and therefore they would know when to take coercive actions or not. Nevertheless, no matter how much information Bletchley Park could intercept, it wasnââ¬â¢t them that would have to deal with the battles themselves. It was the soldiers and sailors that were to enforce these plans into actions, and it was them that had to fight the physical battle, the most imperative part of War. There was always a possibility that the British would suffer heavy casualties at the hands of the Germans, despite the fact that they knew of their intended actions. Other than that sometimes the information was ignored, since it wasnââ¬â¢t considered as something worth taking note of. Bletchley Park helped organise D-Day, on the 6th of June 1944. They helped to provide the Germans with bogus information, making them think that the allied army had camped in an area known to them. In reality, they merely used cloth and wood to reconstruct a camp which seemed real from a distance. So while the Germans were planning to ambush a camp that was non-existent, the Allied forces began the liberation of Europe. But again, it wasnââ¬â¢t Bletchley Park that brought final victory, for it was the army that enforced the information in a beneficial way. It was their actions and organisation offence wise, which made everything successful. After D-Day, Bletchley Park lost its influence. They were ignored when they passed on additional information, because the end of the war truly in sight. In conclusion, Bletchley Park was nothing more than a great help towards the War effort. Their labours was not what finalised the fact that the British would emerge victorious from the War, for it was not they that had to enforce plans and actions amongst men, who have different minds to that of computers. When victory was in their grasp, the Army neglected the information sent to them by Bletchley Park, to no consequence. The end of the war was in sight, as was Bletchley Park.

Law Social Engineering
LAW AS A TOOL FOR SOCIAL ENGINEERING IN INDIA KARANDEEP MAKKAR1 Roscoe Pound introduced the doctrine of ââ¬Å"Social Engineeringâ⬠which aims at building an efficient structure of society which would result in the satisfaction of maximum of wants with the minimum of friction and waste. It involved the rebalancing of competing interests. This article analyses the role of legislations, constitutional provisions and court judgements in the process of social engineering in India.Introduction India, known around the world as a ââ¬Å"cradle of civilizationsâ⬠has always been a queer mixture of various faiths, religions, a place where the cultures of the world meet, constituting an environment of composite culture. It was for this reason that Pandit Jawaharlal Nehru called India the ââ¬Å"the museum of world religionsâ⬠. Indeed, the very paradigmatic setting of India has been pluralist all along. Even today the land mass called India, spread over 3. 8 million sq km of area inhabited by a thousand million plus population, with every imaginable kind of a weather pattern from minus 40 degree Celsius in greater Himalayan region to 50 degree Celsius temperature in the deserts of Rajasthan and temperate weather of coastal regions, 20 official languages written in 16 different scripts, around 2000 dialects, 16 well demarcated agro-climatic zones2 and almost all religions of the world well and adequately represented, presents a mind boggling variety and plurality.And all this has a bearing on Indiaââ¬â¢s liberal, secular, republican, politico-legal system. Under these conditions, it becomes very necessary to have a mechanism for balancing the interests of the individuals, society and the state. India, after independence, adopted the ideal of a socialistic pattern of society and has formulated programmes of social welfare in various spheres. The aim is to establish a social order which would eradicate exploitation, secure equal opportunities for all citize ns, ensure that they share just obligations and enjoy social security.The means adopted in achieving these ideals these ideals are peaceful and democratic. The goal is sought to be achieved mainly through the enactment of suitable laws. It is generally recognised that legislation does create healthy conditions for such changes. It is in these circumstances that law comes into play to act as an agency balancing conflicting interests and becomes a tool for social engineering. This article analyses the 1 2 Student, 3rd Year, B. A. LL. B (Hons. ), Hidayatullah National Law University, Raipur. Data teken from http://en. ikipedia. org/wiki/India accessed on 31-03-2010 role of legislations, constitutional provisions and court judgements in the process of social engineering in India. The Concept of Social Engineering Roscoe Pound was one of the greatest leaders of sociological school of jurisprudence. He introduced the doctrine of ââ¬Å"Social Engineeringâ⬠which aims at building an e fficient structure of society which would result in the satisfaction of maximum of wants with the minimum of friction and waste. It involved the rebalancing of competing interests.Roscoe Pound defined the legal order by reference to the end of law: ââ¬Å"It [the legal order] may well be thought of as a task or as a great series of tasks of social en-gineering; as an elimination of friction and precluding of waste, so far as possible, in the sa-tisfaction of infinite human desires out of a relatively finite store of the material goods of ex-istence. ââ¬Å"3 Interestsâ⬠, ââ¬Å"desiresâ⬠, ââ¬Å"claimsâ⬠, ââ¬Å"wantsâ⬠ââ¬â for the most part the words are used interchangeably in Pound's writings, although ââ¬Å"interestsâ⬠sometimes serves as the inclusive term. He writes, ââ¬Å"For the purpose of understanding the law of today I am content with a picture of satisfying as much of the whole body of human wants as we may with the least sacrifice. I am c ontent to think of law as a social institution to satisfy social wantsââ¬âthe claims and demands involved in the existence of civilized societyââ¬âby giving effect to as much as we may with the least sacrifice, so far as such wants may be satisfied or such claims given effect by an ordering of human conduct through politically organized society.For present purposes I am content to see in legal history the record of a continually wider recognizing and satisfying of human wants or claims or desires through social control; a more embracing and more effective securing of social interests; a continually more complete and effective elimination of waste and precluding of friction in human enjoyment of the goods of existenceââ¬â in short, a continually more efficacious social engineering. â⬠5 Like the engineer, the jurist constructs, creates ââ¬â but not out of thin air.Like the engineer, he must work with resistive materials, without which, however, he could not build at all; and always there are adverse conditions imposed upon his activity. Friction and waste, represented by a sacrifice of interests which might be secured, must be overcome. The task is one for human activity: though requiring methodical care, there is nevertheless nothing static about it. Technique and materials may be improved. Jurist 3 4 5 Pound, Roscoe, ââ¬Å"Interpretations of Legal Historyâ⬠, Harvard University Press, 1946, At P. 160. Pound, Roscoe, ââ¬Å"The Spirit of the Common Lawâ⬠, Transaction Publishers, 1999, At P. 96. Pound, Roscoe, ââ¬Å"An Introduction To The Philosophy Of Lawâ⬠, Transaction Publishers, 1999, at p. 20. must work on, must create an ever greater, ever more serviceable structure. The engineering analogy stands out as both graphic and timely. 6 According to Roscoe Pound, law is an instrument of social engineering. The task of jurists is to find out those factors which would help in the development of culture conducive to the maximisa tion of satisfaction of wants. These factors are principles as Jural Postulates. 7 Technique of Social Engineering:Pound advocated the technique of Social Engineering for the purpose of balancing the conflicting interest of the society, in order to achieve maximum satisfaction of maximum want of the individuals. He advocated that the study of law should be supplemented by social aspects so that it may become more attractive and useful. Spencer and Bentham also in a way directly and indirectly applied law to men in society. Judicial Application: Pound suggested that judicial application of law should take into account the following factors: (a) The factual study of social effects of the administration of law. b) Social investigations as preliminaries to legislation. (c) The means by which the law can be made more effective should be devised. (d) A study of legal and philosophical aspect of judicial method. (e) Sociological study of Legal History. (f) The achievement of the purpose of law. (g) Possibilities of jurisprudence of interests and reasonable solution of the individual case. SOCIAL LEGISLATION AS TOOL FOR SOCIAL ENGINEERING When unequal distribution of wealth exists in a society or when social justice is denied to certain sections of the people, laws are enacted to bring about equilibrium.These laws may be designated under ââ¬Å"social legislationâ⬠. Social legislation tries to remove inequalities and to benefit the whole community rather than a few individuals. It adjusts 6 7 Douglas, Some Functional Aspects of Bankruptcy (1932) 41 YALE L. J. 329, 331. Dr. Laxmikanth, ââ¬Å"Law and social transformationâ⬠, at pg. 6 supplements and sometime replaces the existing legal system. In other words, in addition to ameliorating the social conditions of people, it bridges the gulf that exists between the existing law at the requirements of the society at a given time. Social legislation, in this sense has a special significance. It is different from o rdinary types of legislation in as much as it reflects, the legislative policy of establishing social justice on humanistic and egalitarian principles. The primary functions of social legislations are summed up by Hogan and Inni in following words: (1) To provide for the orderly regulation of social relationship. (2) To provide for the welfare and security of all individuals in the social unit. 9 Social legislation, therefore, aims at establishing social equality in society.The needs of society are adjusted and those who are responsible for creating imbalances or inequalities in society are prevented from doing so. It is however, necessary that all social legislation must be accompanied by ââ¬Å"social preparednessâ⬠ââ¬â by effective propaganda to educate the people about its objects and to convince them of the ultimate utility of a particular legislative measure aimed at promoting the common good and fostering the common welfare. It is only then that the law can give dir ection, form and continuity to social change. The effectiveness of social legislation also depends on attitude of judiciary.Under the traditional approach, the judges usually paid greater heed to the letter of the law and the mischief that was to be removed by the law. Social conditions and economic trend were not supposed to influence him in arriving at a certain decision. But this attitude appears to have changed in recent times. The judge appears to be conscious of the felt necessities of the time. He feels that his duty is not only to point out mistakes of legislature or remove unjustifiable hardships caused by law but also to assist in the social and economic progress of our times. 10 LEGISLATIONS ENACTED FOR THE PURPOSE OF SOCIAL ENGINEERING 9 10 Balbir Sahay Sinha, Law and social change in India, , 1983, Deep and Deep Publications, pg. 25 Hogan and Inni, ââ¬Å"American Social Legislationsâ⬠, Harper and Brothers, New York, at p. 4. Supra Note 7. The introduction of certa in major changes in the Hindu family law is a very important instance of social reconstruction in India in recent times. This has been brought about by such Acts, as The Hindu Marriage Act, 1955, the Hindu Minority and Guardianship Act, 1956, and the Hindu Adoption and Maintenance Act, 1956. The provisions of these Acts are calculated to generate effective means of social control.For instance,Section 12 of the Act prohibits polygamy which was very prevalent in the society before the enactment of the Act. This can be viewed as a measure to balance the interests of the husband and wife as also a means for social control. The socio-economic revolution that has resulted from new land legislations is best seen in rural India. The land reform measures, adopted by the State Governments in the wake of Constitutional amendments, are meant to mitigate the hardships of tenants, strengthen and safeguard their tenancy rights and confer a new status on them.This type of legislation can be rightly regarded as one neutralising the socio-economic disharmony in the rural population. The pitiable conditions and large-scale poverty of the rural population produced a sense of frustration in our peasantry endangering the entire society. The grievances of the agriculturists are being gradually removed by the land reform projects which would ultimately bring about a degree of social satisfaction and create a spirit of co-operation in the masses. 11 The new labour laws are aimed at battering the conditions of the workers in trade and industry.These laws have had an impact on social structure to a large extent. The individual workerââ¬â¢s interest has been given great importance. The freedom of contract between the employer and the employee has been regulated in the interest of the worker and attempt has been made to assure to every worker condition of work ensuring a decent standard of life. A number of important enactments as, for example, The Industrial Disputes Act, 1947, The Mi nimum Wages Act, 1948, The Plantation Labour Act, 1951, The Maternity Benefit Act, 1961 have been designed to curb, if not eradicate, the urge to exploit workers.Thus, they promote the welfare of workers and balance interests of employees and employers hence resulting in social engineering. CONSTITUTIONAL PROVISIONS PROMOTING SOCIAL HARMONY The glaring inequality of different types more particularly based on sex and caste prevailed in Indian society until the pre-independence days, despite continuous efforts by the state, reformers and missionaries to control and eradicate them. The immediate 11 Supra note 7, at pg. 27 task for the Indian people and constitution makers was to establish an egalitarian society.Therefore, in the preamble of the constitution it was declared that ââ¬Å"we, THE PEOPLE OF INDIA, having solemnly resolved to constitute India into a SOVEREIGN SOCIALIST SECULAR DEMOCRATIC REPUBLIC and to secure to all its citizens: JUSTICE, social, economic and political; LIB ERTY of thought, expression, belief, faith and worship; EQUALITY of status and of opportunity; and to promote among them all FRATERNITY assuring the dignity of the individual and the unity and integrity of the nation. 2 The constitutional provisions relating to secularism aim at bringing about integration and harmony in the society. Article 15 of the Constitution forbids a classification on the ground only of religion, race, caste, sex, place of birth or any of them, subject to specified exceptions and Article 16 makes a like provision in connection with public employment with the addition of ââ¬Å"descentâ⬠and ââ¬Å"residenceâ⬠as forbidden grounds of classification. The Constitution gives the right to all persons to profess freely, practise and propagate religion subject to public rder, morality and to other provisions of the Constitution on Fundamental Rights. Thus, in India no religion is given a preferential status or accorded any special privilege and the Constitu tional provisions aim that no person should suffer any disability because of his religion. In order to achieve social progress and political advancement, the practice of untouchability has been outlawed by Article 17 of the Constitution and by the Untouchability Offences Act, 1955 enacted in pursuance of Article 17. These are clear indications to end social equality.The provisions referred to are aimed at effectively balancing the various conflicting interests in the society and form the basis of what Roscoe Pound termed as ââ¬Å"social engineeringâ⬠. A STUDY OF CASE LAWS While Sociological jurists emphasize on the balancing of the conflicting interests of the individual, society and the public through the process which Roscoe Pound terms as the process of ââ¬Ësocial engineeringââ¬â¢, the same has also been witnessed though the action of the Supreme Court when, in Vellore Citizenââ¬â¢s Welfare Forum v.The Union of India13 which is known as the Tanneriesââ¬â¢ case t he Supreme Court observed as ââ¬Å"The Constitutional and statutory provisions protect a personââ¬â¢s right to fresh air, clean water and pollution-free environment, but the source of the right is the inalienable common 12 Bal Gobind, Kashyap, Reformative law and social justice in Indian society, 1995, Regency Publications, New Delhi, at p. 8 13 AIR 1999 SC 2715 law right of clean environmentâ⬠. The Court further observed, ââ¬Å"Our legal system having been founded on the British Common Law, the right of a person to pollution-free environment is part of the basic jurisprudence of the landâ⬠.Thus the Court gave priority of public interest over individual interest. In B. Venkatramma v. State of Madras14, the passing of a communal order by the Government allotting certain vacant posts in government services in fixed proportions to Muslims, Christians, Harijans, Backward Hindus, Hindus, Non-Brahmin Hindus, and Brahmins was taken to be a violation of Article 16(1) of the c onstitution by the Supreme Court. CONCLUSION Rapid change in Indian social life is the result of many factors.The influence of public opinion, the lessons of history, and the examples of progress achieved in other countries, the impact of ideas from the West- all have played a part. The legislative activity in India after independence has been directed, by and large, towards the creation of a new social order. The gap between pressure of changed patterns and the slowly evolving new norms of social life was sought to be plugged by many important laws. To make social engineering through the use of law, the importance of other factors like economic development needs to be realised.Law cannot, by itself play a vital role unless it is accompanied with economic development. Public opinion also plays an important role. There should be awareness amongst the various sections of the society before legislation is enacted for its successful enforcement. The purpose of social legislation like ot her types of legislations is not fulfilled if its enforcement is lax. If laws are evaded by people, this undermines the purpose of legislation, breeds corruption and puts the administrative machinery under heavy strain. This may ultimately lead to disintegration of the society.Hence, rather than passing a number of legislations in this area without making adequate provisions for their enforcement, it is better to have fewer social laws containing clear-cut provisions for effective enforcement. The conflicts in modern Indian society are largely due to the fact that social life has not been properly adjusted to the forces of present age. In order to harmonize our relations in the society, it is absolutely essential that changes in law should be preconditioned by the existing public opinion in the society.In other words, the changes in 14 AIR 1964 SC 572 law should be only in those directions and to that extent which the people in general aspire in the society. Mere super-imposition an d direct adoption of foreign models in their entirely original form can create disruption and disorder in the society. We should retain our own social values and include foreign ideals in such a manner that the latter are fully assimilated and become a part of our social system.
Human resource management Policies and Principle Essay
HRM policies and principles contribute to the effectiveness, continuity and stability of the organization.â⬠Human resource is the set of individuals who make up the workforce of an organization. Any successful organization does not owe its success solely to market realities and sustainable competitive advantages. Successful companies are those that consider their human resource as their most important asset.Human resource is thequalitative aspects, that actually make or break an organization. With this aspect in mind Human resource management becomes a top level priority issue for an organization. Human Resources Management (HRM) is the strategic management of the employees, who individually and collectively contribute to the achievement of the strategic objectives of the organization. Assuming that the employees of an organization are individuals with own mental maps and perceptions, own goals and own personalities, own capabilities HRM holds that the organization should be able to employ both individual and group psychology in order to commit employees to the achievement of organizational goals. The main goals / responsibilities of HRM are: â⬠¢ To retain low employee turnover rate by inspiring people to work for the company â⬠¢ To attract new employees â⬠¢ To contribute to employee development In order to achieve these responsibilities each organization after collecting information and incidents from past experience, employees and other companys define their policies and principle. HRM policies are the guidelines which consist of the terms and conditions of the organization which should be communicated to every employ and which serves as a guide in time of decision making.Each organizations makes its own policy depending on its objective and work environment. Policies are not a hard and fast rules, each organization make policies which are somewhat flexible and can be modified with the consent of majority in order to benefit the organization. Following are some of the policies adopted by any organization and its contribution to effectiveness, stability and continuity of the organization: 1.Policy of hiring people with due respect to factors like reservation, age, marital status, sex and the likes 2.Policy on terms and conditions of employment ââ¬â compensation policy and methods, hours of work, overtime, promotion,transfer, lay-off, retirement and the likes 3.Policy with regard to medical assistance-sickness benefits and ESI and company medical benefits 4.Policy regarding training and development-need for,method of, and frequency of training and development 5.Policy regarding housing, transport,uniform and allowances 6.Policy regarding industrial relations-trade-union recognition, collective bargaining, grievances procedure, participative management, and communication with workers. Hrm principles Principles are universal truths generally applicable to all organizations. Principles guides managers to formulate policies, programmes,procedures and practices. Following are some principles which any organization follow and how they contribute to the effectiveness, continuity and stability of the organization:- 1.Principle of individual deveploments to offer full and equal opportunities to every employee to realize his/her full potential. 2.Principle of scientific selection to select the right person for the right job 3.Principle of free flow of communication to keep all channels of communication open and encourage upward, downward, horizontal,formal and informal communication 4.Principle of participation to associate employee representatives at every level of decision making 5.Principle of fair remuneration to pay fair and equitable wages and salaries commensurating with the jobs 6.Principle of incentives to recognize and reward good performances 7.Principle of dignity of labour to treat every job and every job holder with dignity and respect 8.Principle ofoflabour management co-operation- to promote cordial industrial relations 9.Principle ofof team-spirit to promote co-operation and team-spirit among employees 10.Principle of contribution to national prosperity to provide a higher purpose of work to all employees and to contribute to national prosperity.

The Things They Carried Essay Example | Topics and Well Written Essays - 1000 words - 1
The Things They Carried - Essay Example The burdens that the characters carry manifest themselves even before they arrive in Vietnam. In the story ââ¬Å"On a Rainy River,â⬠the narrator Oââ¬â¢Brien explains the events that led him to Vietnam in the first place: ââ¬Å"In June of 1968, a month after graduating from Macalester College, I was drafted to fight a war I hatedâ⬠(44). As a pacifist, he did not believe in going to war, so he contemplated running away to Canada. With his opposition to the war, Oââ¬â¢Brien felt that he could not carry the burden of participating in Vietnam; however, these personal burdens were not the only ones that were weighing upon him. He felt that by becoming a deserter, he would become a burden upon his family: ââ¬Å"They carried the soldierââ¬â¢s greatest fear, which was the fear of blushing. Men killed, and died, because they were embarrassed not to. It was what had brought them to the war in the first place, nothing positive, no dreams of glory or honor, just to avoid t he blush of dishonor. They died so as not to die of embarrassmentâ⬠(16). These motivations run contrary to the traditional motivations for going to war; he at no point considers going to war for patriotic reasons or for dedication to the ideals and causes of his country. Wanting to not disappoint his family, Oââ¬â¢Brien decides that the burden of going to Vietnam contrary to his political beliefs was less of a burden than the ramifications of his draft dodging. Vietnam weighed heavily upon Oââ¬â¢Brien, and he had not even been to the country yet. Among the necessities or near-necessities were P-38 can openers, pocket knives, heat tabs, wrist watches, dog tags, mosquito repellent, chewing gum, candy, cigarettes, salt tablets, packets of Kool-Aid, lighters, matches, sewing kits, Military payment Certificates, C rations, and two or three canteens of water. Together, these items weighed

NKCC cotransporter Essay Example | Topics and Well Written Essays - 3000 words
NKCC cotransporter - Essay Example Of these NKCC1b is also known to be found in brain RNA (Gamba, 2005). It is noted here, though, that the two isoforms of the NKCC1 cotransporter is found only in the European eel (Anguilla anguilla) as per research of Cutler and Cramb, 2002. Nevertheless, there is ample evidence that NKCC1, in human and other mammalian species, is functionally implicated in CNS cells. It is observed by Gamba, 2005, that the NKCC1 cotransporter is activated by receptors and assists in neurotransmission by driving anions into the cell. It is also observed by Strange et al, 2000, that the work of the NKCC1 cotransporter complements that of the KCC2 one. The choice of the culture medium, the neuronal-specific CAD cell line, and the somewhat CNS-specific NKCC1 dovetails perfectly for a research attempt that seeks to establish new facts on the molecular identity and other expression patterns of these unique electroneutral cotransporters in cells of the central nervous system (CNS). G. Gamba's excellent 200 5 review article on these cotransporters has been extensively used in this paper because it is the most comprehensive document prepared to date being inclusive of all aspects described so far. The cation-coupled (Sodium and ... The Cation-Coupled Cotransport System The cation-coupled (Sodium and Potassium cations only) chloride cotransporters are a unique transmembranal transport system that is electrically neutral yet very effective in action (Gamba, 2005). These cotransporters constitute a secondary transcellular transport system that complements the primary cation transcellular transport system - the one mediated by the enzyme --ATPase. In the primary system the mover is an electrochemical gradient while in this chloride cotransporter system there is no such gradient, the reason why it has acquired the electroneutral label, and imbalances in chloride anion concentrations between intracellular and extracellular media constitute the prime mover of the system (Gamba, G., 2005). In absorptive and secretory epithelia there is need to transport ions and solutes in and out of the cells. Specific plasma membrane proteins mediate this transport system by either effecting sodium influx and potassium efflux with accompaniment of those ions and/or solutes that need to be transported (Gamba, G., 2005). Except in choroidal plexus, these cations move through the epithelial basolateral membrane mediated by the action of the enzyme --ATPase that creates an electrochemical gradient across the membrane. The plasma proteins mediate this transcellular transport that utilises this gradient to move target ions across the membrane and thus this system is called a secondary one while the enzyme-mediated cation movement is called the primary system. These two component systems together constitute the primary ion transport system across cellular membranes in human physiology (Gamba, G., 2005). On

Beggaining of catholic Essay Example | Topics and Well Written Essays - 500 words
Beggaining of catholic - Essay Example Jesus of Nazareth was an itinerant preacher in Jerusalem during the Common Eraââ¬â¢s early 30s. Catholicism is strongly founded on the death, resurrection and ascension of Jesus Christ. In this regard, the proclamation of Catholic Church is that the death of Jesus Christ was for intended for this church. In addition, Catholicism was built and established on by the apostles through Peter who is believed to have been given the Keys to Heavenââ¬â¢s Kingdom. Peter was also given the power to loosen and bind that which is bound in Heaven. At this point, the Catholics believe that Jesus gave Peter the obligation to serve as the head of the Church under the authority of Jesus (Norman, p.8). After Jesusââ¬â¢ resurrection, His mission of bringing salvation to man was complete. However, one would only obtain salvation through encounter with Jesus in baptism and becoming a disciple. This way, the church would be established. Holmes and Bicker reveal that with Peter as the churchââ¬â¢s head, the other disciples assisted in the mission of disciples making in the world as Jesus had commanded. Through this mission, the word Catholic was used to mean universal, which also means the Catholic Church reaching around the world. The Pope and Bishops head the Catholic Church congregation. The roles of the Pope originated from Peter the church head, while the disciples were replaced with bishops. The Pope is considered to be the successor to have succeeded Peter whose grave is in Vatican City today. At first, the Roman Catholic Church in the Roman Empire was prohibited. In this empire, Christians were under terrible prosecutions. These conditions lasted for about three hundred years until the reign of Emperor Constantine (Vidmar, p.10). The conversion of Emperor Constantine into Catholicism made it legal and eventually recognized as the religion for the empire officially. Constantine legalized Christianity in A.D.

Planning Your Visit Research Paper Example | Topics and Well Written Essays - 1000 words
Planning Your Visit - Research Paper Example In the following parts of this paper, serious health ramifications have been described and highlighted as well. It is followed by personal experience part where the personal observation has been provided. Before the conclusion part, legislative authority and meeting with the legislative authority has been included. All types of cancer can be caused by smoking. In the United States, 9 out of 10 smokers first tried cigarettes by the age of 18 (U.S. Department of Health and Human Services, 1994; U.S. Department of Health and Human Services, 2012; Campaign for Tobacco-Free Kids, 2009); and around 3,200 individuals below the age of 18 smoke first cigarette (U.S. Department of Health and Human Services, 2012; U.S. Department of Health and Human Services, 2014); more seriously smokeless cigarette and hookah are becoming popular in middle and high school students (Centers for Disease Control and Prevention, 2013). Smoking in the earlier stage of life may not highlight severe effects at the initial stage of smoking especially for the youth. However, with the passage of time, smoking starts to show its effect on internal body functions and body activities. At the same time, the chances of asthma and other breathing problems cannot be also ruled out as it is difficult to ascertain and predict the likely potential hazardous effects of smoking on human body. Subsequently, in the long run, chances of other physical, psychological complications cannot be avoided. With my personal experience, I can surely say that smoking puts devastating effects on the entire family fabric in which every family member is affected. In my neighborhood, one familyââ¬â¢s teenager used to smoke cigarettes. And his parents always remained worried about him. More often, I used to hear family problems and other issues. In other words, this unfriendly relation was mainly caused by the smoking habit of the teenager. More

Explain the advantages and disadvantages of starting a business from Essay - 1
Explain the advantages and disadvantages of starting a business from scratch, franchises, and existing businesses - Essay Example s include the freedom to implement oneââ¬â¢s ideas to a large extent, aligning the investment and resource mobilization with market conditions rather than committing to rigid plans, and ease of entry and exit with minimum dependence on outsiders (Longenecker et al, 2011, pp.104-133). Disadvantages include high risk of venture failure due to lack of previous experience, making a wrong choice of product/service, and longer time needed to achieve physical and financial goals. Outright purchasing of an existing business denotes a medium risk and gives assured customer base and revenues from the start. This advantage is diluted if the unit has poor reputation for quality or ethical practices. While the experienced staff is an advantage, if there are unresolved industrial relations problems, the new owner has to solve them, which is not always easy. Also, it may not always be possible to identify hidden liabilities representing additional risks, which accrue to the new owner (ibid.). Taking out a franchise is a minimum risk option for new entrepreneurs since it provides the advantages of a new unit as well as a running business model. On the minus side, one has to depend on the parent company for all major decisions besides committing to pay initial fees and royalties. Profitability is reduced as a result of these limitations. One of IFAââ¬â¢s best features is the listing of several franchise options, complete with the preliminary information for analysis, negotiations and decision making. I have considered the option of Expediaà ®CruiseShip Sales Center Franchise from IFAââ¬â¢s website for analysis (Franchise opportunities, IFA, 2012). This is an established company with a strong brand image and 150 franchises. With an initial investment of $9500 and total investment of up to $20,000, this business is within my reach (ExpediaFranchise, 2012). The business is related to travel and vacation for which the demand has always been good. Further, a franchisee can start operations

FARs and Aircraft Dispatch Research Paper Example | Topics and Well Written Essays - 750 words
FARs and Aircraft Dispatch - Research Paper Example Though they are known by many different names, including flight dispatcher, airline dispatcher, flight superintendent, or even flight controller, the job description essentially remains the same: ensure compliance with all applicable regulations and the pursuit of the highest possible levels of safety (ââ¬Å"Airline dispatcher federationâ⬠, 2011). The job of an aircraft dispatcher is covered in the Federal Aviation Regulations (FARs) in several areas, namely FAR Part 121 and FAR Part 65, both under Title 14 of the Code of Federal Regulations (CFR) (ââ¬Å"Code of federalâ⬠, 2010). FAR Part 121 covers Operating Requirements: Domestic, Flag, and Supplemental Operations, while FAR Part 65 covers Certification and Eligibility Requirements (ââ¬Å"Code of federalâ⬠, 2010). Simply put, these sections of the Federal Aviation Regulations ensure that an airline dispatcher has the proper training and certification to do their job, as well as adhering to duty-time requirements w hile on the job, to prevent overtiredness and accidents. These regulations also cover the overall requirement of having enough dispatchers in the dispatch centers to handle all of the flights, so that no one dispatcher feels overwhelmed and unable to do their job. FAR Part 65, Subpart C, completely covers the eligibility and certificate requirements that any person wishing to become an aircraft dispatcher must complete. The requirements include criteria such as an age requirement of 23 years, the ability to speak and understand English, and passing both knowledge and practical tests. These tests must be completed after a certification course that consists of 200 hours of training, though previous experience may be submitted to cover part or all of the hours (ââ¬Å"Code of federalâ⬠, 1998). It also plainly states that no person may serve in the capacity of airline dispatcher without said completion certificate, and must present that certificate upon the request of numerous pers onnel (ââ¬Å"Code of federalâ⬠, 1998). These regulations enable the airlines to work in conjunction with certified, capable individuals, helping the aircraft dispatcher to do their job by ensuring that they have the proper training and certification to complete it adequately. The safety of numerous passengers flying on the airlines that are the responsibility of the dispatcher are not to be taken lightly, and indeed, the dispatchers pledge to uphold safety as much as the pilots. Therefore, having these training and eligibility requirements help to ensure that the job and what it entails is taken seriously. FAR Part 121, Subpart M: Airmen and Crewmember Requirements, also applies to aircraft dispatchers. FAR à §121.395, in fact, covers dispatch centers, stating that enough qualified dispatchers must be working to ensure proper operational control of aircraft (ââ¬Å"Code of federalâ⬠, 2010). Without this regulation, a flight load could easily slip into the chaos of an und erstaffed and overworked dispatch center, causing costly losses of life and aircraft. Given the fact that downsizing has become popular, it is a relief to know that dispatchers are aided by this regulation, as enough of them must be working to reasonably handle a typical daily flight load for an airline. FAR Part 121 does not stop there in covering airline dispatchers. In Subpart P: Aircraft Dispatcher Qualifications and Duty Time,
Incorporating Ethical Standards Essay Example | Topics and Well Written Essays - 1000 words
Incorporating Ethical Standards - Essay Example That is all that is needed to perform a full background check on the person using advanced HR information technology. A simpler and less digital solution would be to ask each employee for a certificate of good conduct. Performing other medical checks such as blood checks for high cholesterol and another physical test can help the company create a wellness program to increase the quality of life of its employees. 2. Incorporating ethical standards is beneficial in both the creation of contracts and technology information systems. Ethics can be included indirectly in a contract by incorporation clauses that include social corporate responsibility initiatives. For instance, a contract can stipulate that the transportation vehicles used to move merchandise must be green vehicles that use an alternative fuel other than gasoline such as trucks powered by natural gas. Including ethical clauses can serve a social purpose, but often the inclusion of social clauses increase the operating costs of a company. Ethics can help legitimize an information technology system. ... à The HR department must incorporate safeguarding protocols to ensure nobody has access to the privilege information written in the contracts. The use of privacy in the workplace can be considered an ethical action. 3. In your response, you mentioned that technology keeps evolving at a rapid rate. I completely agree with your statement. Mooreââ¬â¢s Law states that the speed of computing power doubles every two years. As computing power increases the consumer benefits because people are getting better computers at cheaper prices. In certain industries inflation negatively impacting costs. The cost of a developing a new drug during the last five years has increased from $800 million to $1.2 billion. Pharmaceutical companies need to find ways of incorporating technology to lower developmental costs. 4. People that work as telecommuters do not have boundaries at work and personal life become the same. A way for a telecommuter to separate home life and work is by creating a special o ffice in their homes where they perform their work. I believe that ethics is very important for people working as telecommuters. Due to the lack of supervision telecommuters must act ethically and comply with the code of conduct of an organization. It would be unethical for a telecommuter to drink alcohol while performing work for the company. 5. A few years ago I worked at a company that had an IT specialist that often acted very unethical. He was constantly using his access to information to snoop into other employeesââ¬â¢ lives.

Treatment of wastewater for reuse purposes Research Paper
Treatment of wastewater for reuse purposes - Research Paper Example Wastewater can be filter and treated to be from all of the containments or some of the containments. Wastewater can be utilized in many applications. Wastewater can be utilized in the agriculture in both the treated and untreated forms. Untreated wastewater is rich is macro nutrients and thus the crops easily in untreated wastewater but it is not environmentally safe as it posses danger to the biodiversity of region. The chemical in the untreated wastewater can easily enter into the food chain and thus can harm the human life. Treated wastewater is not only goof for the plants but also for the environment. Wastewater can also be utilized for the industrial purposes. It can be utilized to cool down the internal combustion engines that generate power in the power plants and to reduce the temperature of the steam in the steam turbine generators. Introduction The increase in the population of the world proposed many problems. One of the major problems is the shortening in the supply of p ortable water. The fresh water sources are depleting as the population is increasing. On the other hand, the natural hydrologic cycle is much affected by the impact of human activity. One way to reduce the burden on the fresh water resources is to reuse the wastewater after treating it and then utilizing it for various purposes. The process of treating the wastewater not only makes the water safe of the biological environment but also for the industrial purposes. Today, an average home consumes as much water in a month that our ancestors have used in years. The modern water utility habits in urban regions made some parts of the world to remain in the water stressed regions. Most of the rivers in the world are unable to reach the oceans due to the heavy human burden on the rivers. Water reuse is the only key to reduce the impact on the portable water resources in the world. There are several techniques to treat the waste water. All the evolved processes have different economic aspect s. The basic sewerage wastewater treatment system ascorbic digestion method consumes less energy and utilizes the natural biotic microorganisms to make the water safe for the environment. How in order to attain the drinkable quality, it undergoes different other steps like the disinfection, sedimentation filtration, filtration, etc. The water quality is considered to be environmentally safe after ascorbic digestion and can be used for the irrigation purposes. The water quality produced thus is rich in nutrients that are made during the breakdown of the sewage wastes and thus good for the agriculture (Drechsel, Scott, Raschid-Sally, Redwood & Bahri, 2009). In urban localities this type of water is safe after disinfection it and removing slug from it. This water is safe for drinking after undergoing different processes but most people prefer not to take this water as the primary drinkable water. It is most utilized to flush the toilets and for laundry purposes (Tchobanoglous & Burton, 2003). Water treatment can be 100 percent efficient or more than 100 percent. It means that the

Lifespan Development Essay Example for Free
Lifespan Development Essay Set forth by Margret Baltes, Paul Baltes and their associates, the life span perspective is the viewing of human development as multi directional, multi cultural, multi contextual,multi disciplinary and plastic. Human development is viewed as multi-directional because with time the characteristics of a human tend to change. Each personââ¬â¢s body consists of a large amount of genes and therefore bring the possibility of having several different directions that they could develop. Different events in life can lead to a change in direction. Some examples of those events may be the death of a loved one, losing a job, getting married, getting into college. etc. Researchers have used the multi directional perspective to figure out that losses and gains tend to occur simultaneously and that losses can lead to gains and gains can lead to losses. Human development is seen as multi contextual because it occurs in various contexts such as physical surroundings and the constellations of family. Urie Bronfenbrenner was the first to shine light on the need to consider multiple contexts. He recommended that when conducting a developmental study we should use an ecological-systems approach. This involves the belief that the individual should be considered in all contexts and interactions that life consist of in the study of human development. Bronfenbrenner later changed the name of this approach to bioecological to show the natural and biological aspects of this theory. There are three nested levels that each person is affected by. Microsystems is immediate surroundings such as friends, school, church and family. Exosystems is local institutions such as place of employment, school, and religious courses. Macrosystems involves the larger contexts such as political, economics and culture. Bronfenbrenner created a fourth system called mesosystem that connects all the systems together. An example of mesosystem would be the connection between family and employment. Family leave policies and overtime are examples of family and employment connections. Bronfenbrenner created the chronosystem or time system which also has an affect on the other systems. Development is viewed as multi cultural because there are many different cultures in the world today. Social scientists describe culture as a ââ¬Å"meaning and information system, shared by a group and transmitted across generations, that allows the group to meet basic needs of survival . . . pursue happiness and wellbeing, and derive meaning from lifeâ⬠(Matsumoto, 2009) Development is multi disciplinary because researchers must study various disciplines to understand it. Scientists usually break the study of human development into three segments to study it better. The segments are biological, cognitive and social. Each segment is a discipline that a scientist specializes in. It is also segmented in age groups such as childhood ,adolescence and adulthood. Development is plastic because the traits of humans can be molded much like plastic and people are durable like plastic. Two Theories of Life Span Development The first theory is Erik Eriksonââ¬â¢s theory of psychosocial development. He believed that personality was developed in stages. One of the main aspects of Eriksonââ¬â¢s theory was the ego identity. This is the conscious sense of self that we develop during social interactions. According to Erik, it is constantly changing as we experience new things and learn new information during our daily interactions with others. Erikson also believed that behaviors and actions were motivated with a sense of competence. Each part of Eriksonââ¬â¢s theory involves becoming competent in an area of life. The individual will feel a sense of mastery referred to as ego quality or ego strength if the stage is handled well. The person will feel a sense of inadequacy if the stage is not handled properly. He believed that people experienced a conflict that acted as a turning point during each stage. In his view, these conflicts were focused on creating a psychological quality or failing to create a psychological quality. The second theory is Jean Piagetââ¬â¢s theory. His theory is composed of four stages. The sensorimotor stage is from birth to 2 years and suggests the the child builds a set of concepts about reality through physical interactions. Preoperational stage occurs between ages 2 and 7. The child is unable to understand logic and cognitive thinking. They understand symbolic things and have acquired motor skills. Concrete operational stage occurs between the ages 7 and 11. Children are aware of external events. They develop operational thinking and can show logical reasoning. The formal operational stage occurs from the age of 11 to 16 and onward. Those who reach this stage have developed abstract reasoning and can easily think logically. How Heredity and Environment Affect Development Heredity and the environment both play an important part in human development. The heredity factors affect all aspects of development. Genes have a tremendous affect on the birth, puberty, growth and death of a human being. Many traits are inherited from our family members and determine how we develop. Our genetics help to determine how we might act. For example, if there is a history of mental problems in your family then you might be prone to mental illnesses as well. The environment also helps in the human development process. The way we act, dress, talk, etc can be affected by our surroundings. For example, if you are raised in ââ¬Å"the ghettoâ⬠then you might be prone to violence, drugs, baggy clothes, and slang talk. Growing up around violence and drugs might make a person develop into a drug abuser or participate in violent activities. The people we surround ourselves with also affect our development. If we are surrounded by violence and drugs then we might think that it is a normal way of life and we might also participate in these activities. If we are not subjected to these types of activities then we have a less chance of getting involved in these activities. Conclusion In conclusion, the life span perspective sheds light on the many aspects of human development. It is multi directional because our lives can go in many directions as a result of different life changing events. It is also multi cultural as there are several different cultures involved. There are many different contexts involved in human development such as our physical surroundings and family constellations. Multiple disciplines are studied in order for researchers to understand human development. Human development is also referred to as plastic because it can be shaped and molded just like plastic. Our development is greatly affected by genetic factors and environmental factors such as inherited qualities and the people and activities we are surrounded by.

Strategic flexibility in interpersonal relationships.
Strategic flexibility in interpersonal relationships. REFLECTIVE PAPER How many times have you heard someone say something like this: ââ¬Å"he just doesnt understand meâ⬠or ââ¬Å"there has been a breakdown in communications between usâ⬠? Lack of good communication between people is a constant problem. As the author, Richard, points out in the first chapter, ââ¬Å"The Communication Processâ⬠, communication skills are crucial to both getting the best out of people and extricating oneself from difficult situations. Nowhere is this more evident than in the personal relationships we form with family and friends. The author introduces the idea of ââ¬Å"Strategic Flexibilityâ⬠(SF), which means that a person uses every communication tool he has in order to effectively get his point across in a given situation. SF is not limited to words but expands into a whole ââ¬Å"communication repertoireâ⬠that can include gestures, expressions, body language and tone of voice. SF is characteristic of people who are successful not only in their professions but in their personal relationships as well. The authors description of SF has six steps: anticipate circumstances; assess the factors and conditions you find yourself in; evaluate the current situation in relation to your own abilities; select the most relevant communication skills you possess; apply the first 4 steps carefully; and reassess your communication after receiving feedback. Finally, creativity is also key to communicating effectively as it allows the speaker flexibility and adaptability. In applying this model to my own life, I began to consider some of my friendships and how they have either been strengthened or weakened because of a certain style of communication between us. Some years ago I had a friend I became quite close with very quickly called Julia. She was exuberant, funny and full of drama. We not only worked together but also went to bars together, out dancing, to comedy clubs and generally palled around. Hanging out with her was full of extreme ups and downs. At one point, Julia was having a great deal of trouble getting what she needed from her immediate supervisor, Rob. Rob and I were also friends. Julias frustration with Rob and Robs frustration with Julia was beginning to affect everyone else who worked with them. I offered to speak to Rob alone on Julias behalf, thinking that hearing some of her complaints and concerns from a third party might make Rob more receptive after all, he and I got along smoothly. I took Rob out for a drink and noticed immediately how uncomfortable he was. His body language said it all he found it hard to make eye contact, was hunched over in a corner of the table and smiled nervously from time to time. He really did not want to hear any of what I had to say. I had an idea in my head of the role I wanted to play with Rob. I planned to be firm and reasonable and to avoid raising my voice or showing anything but understanding that the dynamic between him and Julia was problematic. But I thought that I could help fix it if only I could get Rob to agree to have more regular and business-like meeting with Julia where they could discuss their issues and, with luck, sort them out effectively. But what wound up happening is that although I kept my voice even, all I did was put Rob on the defensive. I never really asked him for his side of the story and just assumed that everything Julia told me was the way things really were. I had arrived with this assumption because I knew others had occasionally found Rob difficult to communicate with. He could be a bit dry and sarcastic. But he was also very driven and good at his job, which was quite demanding in a number of ways. It did not occur to me to ask him how the pressures of his job and his frustra tions with Julias work style might be affecting the outcome of the department he headed. Needless to say, nothing came out of this meeting with Rob. As I spent more time around Julia, it became obvious to me that her way of dealing with problems was to give way to emotional outbursts rather than find a clam and thought-out way of telling people including Rob and, by then me what was troubling her. I myself made the mistake of confiding in Julia at a time when I was feeling very vulnerable and she wound up throwing back what I had told her in my face. I started to learn at that moment that being more careful about how and with whom I communicated with would have a direct effect on my happiness in both my work and personal life. The way to communicate with someone who tends towards being emotional is not to meet it with the same level of emotion but rather to step back and try to diffuse the situation by giving the person a chance to vent and then thinking before responding. This way, there is a better chance that ideas can flow peacefully between the parties. I am also much more receptive to body language now. If I was trying to speak to someone who was hunched over and not meeting my eyes, I would know immediately that the style of communication I was using was making the other person uncomfortable. Using the SF tools, I would try to be more mindful of the sender-receiver mode the author writes about. I did not receive messages properly or chose to ignore them, acting only as a sender. This one-sided communication style was probably the reason my attempt at peacemaker failed. My nonverbal communication was equally lacking. I could have made Rob more at ease by leaning back in my seat instead of leaning forward as if ready to attack. I could also have given him a reassuring tap on the arm or shoulder to indicate friendship and empathy. I did not listen to the indirect feedback Rob was giving me. I did not respond to his obvious discomfort nor did I really give him a fair hearing. I think choosing a bar was not a bad idea as it was a neutr al zone for both of us, but selecting a quieter bar than the one we went to also would have been a better choice, as it is hard to stay focused when people are playing pinball next to you! By ignoring Robs side of the situation and not doing much to make him feel he was not under attack, I also did not apply the ethical standards the author outlines, such as treating opposing views with respect. I do make a concerted effort to apply many of the standards of ethical communication in my relationships now. 2. Perception Self-perception, as well as perceiving the needs of others, plays a vital role in effective communication, an idea that is discussed at length in the second chapter, ââ¬Å"Self, Perception and Communication.â⬠The relationship between self-image and perception of both self and of others is immensely complicated. Low self-esteem can feed into other peoples perceptions of a person through signals in their body language, tone of voice and facial expressions. These in turn, can reinforce negative self-image when other people respond to the negative signals they are receiving and send them back again to the initial communicant. Stepping outside ones comfort zone by engaging in ââ¬Å"risk-takingâ⬠can create a fundamental threat to self-identity. As the author points out, ââ¬Å"to take that action, or have that experience, would so violate who you are that, should you do it, you would no longer be the same person. You would be forced to see yourself as someone different.â⬠Yet this very act of questioning identity can be enormously empowering. I grew up a fairly withdrawn child. I did not relate well to my peer group and was always more comfortable around adults or animals. I was afraid of judgment, or being teased. My grandmother had me outfitted at an expensive department store twice a year, which just created a further separation between my peers, whose parents tended to shop at Sears and local shops on an as-needed basis and me. My clothing communicated that I thought I was better than everyone else even though that image could not have been further from the truth. The author points out that ââ¬Å"Social comparisons are pivotal to self-evaluations. They depend less on objective circumstances than on how you judge yourself in relation to others on particular attributes.â⬠This was certainly true of my school days. Because of my distance from and fear of my classmates, I retreated into the library during most recess periods. My bookish behavior again reinforced that I was different. The fact that I did not voluntarily engage with my classmates on the playground even though a big part of me wanted to made me even more of a target for teasing. In short, every method of communication I was using, from my clothing, haircut, behavior and choice of pastimes communicated that I was a snob, even though my self-esteem was shaky and all I really wanted was to fit in. As I grew up and realized the value of a certain level of conformity, my fortunes shifted. I started to dress in the same brand jeans as the cool girls, wore the same style of shoes and makeup and made sure my hair was cut in one of the latest fashion trends. These changes told my peers that I was becoming like them. They started to treat me as a friend. Even so, I always felt a need to stand apart from the pack, to be noticed. The solution turned out to be through acting. I took up theater classes, dance and singing and performed in school plays. By pretending to be someone else on stage, I could feed that need for to be someone different while still being one of the gang. I could take risks as another persona that I could not take in my real life. After many years, I am still learning how to read people better instead of assuming they think the worst of me automatically. I have found that it is important to try to read people, to try to understand their own self-perceptions and the way they view their environment. These observations act as the feedback mentioned in the SF description. In this way, I can better react to what people are actually saying to me (rather than acting out of irrational fears) and adjust my own body language, word choice, even my dress in order to establish a rapport. This becomes very important in interviews and work situations. I have had jobs where my employer was excellent at communication and somewhere the communication was lacking. In the case of the former, I once worked for a professor who was very good at giving me work that matched my level of competence but that also helped stretch my skills set. When he gave criticism, it was also in a gentle tone of voice. He used words that were not judgmental but instead focused on showing me how I could improve my work with a few adjustments or a change of direction. An important quality Jeff had was that he was also always willing to listen to my ideas, help me develop them and would give me credit for work that was uniquely mine. Jeff was a great example of someone who had the SF concepts down pat and used them every day in his dealings with staff. Jeffs method of communication was a pivotal experience in my work life. It helped build my sense of ability and encouraged me to think for myself. Because Jeff was such a supportive boss, I also worked harder to please him and took greater pride in producing quality work. I began to learn how to argue a point effectively, and without becoming emotional. I did this by consciously separating my ideas for the project at hand from things I had been told as a child. I forced myself to listen to criticism because it was given in a gentle and well-intentioned way. Jeffs style was one of the stepping-stones in transforming not only my perceptions about my own abilities but my ability to learn and grow in a job. 3. Listening Listening is also a skill upon which I have improved, even though this has required a good deal of effort. True listening means often having to force yourself not to react, at least not immediately. Listening requires more than simply hearing what another person is saying. It involves paying attention to the use of words, body language and expressions, and also trying to put yourself in the shoes of the person speaking. The more you make an effort to understand the perspective from which they are communicating, the more I feel you are truly listening. I have found this to be especially true with family. Often, there is a lot of emotional baggage we carry around from the things our parents and siblings said to us when we were very young, a point the author makes repeatedly. The author likens our self-perception to a map: ââ¬Å"What this means for you is simply that your perception of reality is not reality itself, but it is your own version of itââ¬âyour ââ¬Å"maps.â⬠But these maps are not necessarily complete pictures of who we are, or of who we are capable of becoming, just like a road map does not necessarily show every tree, brook and signpost on a route. You can always use a different map or a different route to get to the same, or even a different, place. Again, the idea of flexibility in the SF concepts applies, since taking a different road can make for a pleasanter journey. This also means, however, that no two people are working from exactly the same map. Listening is therefore crucial to being able to find your way along another persons route. Keeping in mind that the way one sees the world or a particular problem may not be the same as the person you are conversing with. Preconceived notions or ââ¬Å"perceptual filtersâ⬠, as the author refers to them, can keep people from actually listening to each other. It is therefore important to try to keep both the mind as well as the ears open in order to foster communication. Conversely, shared experiences, where they arise, can also cement relationships. My siblings and I share many of the same experiences but have very different perspectives about them. I have learned a good deal about who they are as people by listening to them expand their views, and it has also influenced how I now see myself in relationship to them and our parents. Only by taking the time to listen can you find those synergies wi th other people and develop healthy and productive communication.
Detection of Vanadium Using Immobilizing 4-(2-pyridylazo)
Detection of Vanadium Using Immobilizing 4-(2-pyridylazo) Naked eye detection of vanadium using immobilizing 4-(2-pyridylazo)-resorcinol on functionalized HMS Mohamad taghi Samadi1, Abas Afkhami2, Kadijeh Shamsi 1, *and Abdolmotaleb Said mohamadi1 abstract In this work, inexpensive optical sensor for the naked eye detection of vanadium by immobilizing 4-(2-pyridylazo)-resorcinol on the functionalized hexagonal mesoporous silica via N-trimethoxysilylpropyl-N,N,N-trimethylammonium chloride in aqueous mediae has been used. The effects of several factors such as pH, reaction time, amount of the material, and the presence of various concentration HMS-TMAC-PAR has been studied so as to optimize operating conditions. The detection was result the color change of PAR complexation with vanadium as of orange-yellow to purple in alkaline solutions. Furthermore, the good performance of the hexagonal sensors was dependent on main factors such as, the reaction time, and the pH value that showed possible naked-eye detection of vanadium concentration of special interest was that our mesostructured sensor design supply control over the retention of the potential functionality of the naked-eye sensing system of vanadium ions upon the storage and even lat er several regeneration and reuse cycles, indicating wide-scale reversibility of sensing methods. The detection and quantification limits for the method when determining vanadium were 40 ppbââ¬â400 ppb, respectively, with a correlation coefficient of 0.99. Good chemical stability of the substantial was seeing for a period of several months. Introduction Vanadium is ordinarily distributed in the earthââ¬â¢s crust but in little profusion. Vanadium at trace amounts represents a vital element for normal cell growth, but can be toxic when present at much concentration(1). the combustion of fossil fuel are described as one of the important sources of environmental pollution by vanadium since coal and oil are in among the richest sources of the metal . Usual deposits of vanadium in coal and basic oil vary amid 1 and 1.5Ãâ"103 mg/kg and it has been estimated that different 65Ãâ"103tons are released into the environment every year by natural discharges such as volcanoes and 2Ãâ"105 tons by anthropological resource(2). The concentration of vanadium in water is largely dependent on geographical position and ranges from 0.0002 to more than 0.1 mg/litre in freshwater(3). the selective and sensitive detection of low concentrations of vanadium is very important (4). Though several methods are available for detection (AAS/AES[1] ÃËÃ
âI CPMS[2] , ICPEAS[3] (1, 5) but these methods are expensive, need sophisticated apparatuss and require extreme control of experimental procedures or unavailable for the on-site detection. The field of optical chemical sensors has been a growing research area over the last three decades. Chemical sensors are miniaturized devices that can supply real time and on-line information on the presence of specific compounds in even complex samples(6) In the last years,have seen the appearance of mesoporous silicate-based sensing uses. Sensor system Mesoporous silicas, with large BET surface area, narrowly distributed pore size, high porosity(7), have shown unlimited potential for sensing applications in new years. Morphological control gifts them versatility in the mode of arrangement whether as monoliths, mass powders, thin films, or implanted in coatings. Great surface areas and pore sizes greater has made them effective as adsorbent. This elude the leaching that can occur from physical enca psulation and mesopores can allow accessibility of analytes to many of active locates systems, UV-visible spectrophotometry has been often used for quantitative determination of analytes(8). According to the recently research, The hexagonal mesoporous silica (HMS) is a material with high specific surface area and large pore diameter. HMS mesoporous silica has been first presented by Pinnavaia and co-workers(9) . present 0f high surface area and uniform pore size that make HMS suitable for catalyst supports(10) Moreover, Modifying the silica wall surface with organic groups to make their characteristic and achieve specific goal(11). A inexpensive visual sensor for the optical detection of very low concentrations of many heavy metal based on functionalization with 4-(2-pyridylazo) resorcinol (PAR)(12). Its color changes from yellow to red while complexed with metal ions such as Cu2+. Various applications for PAR and its similarities have been put into practice. Therefore a different heavy metal ions responsive optical sensor (HMS-TMAC-PAR) has been prepared by grafted surface functionalization of the original HMS with (TMAC[4]) and then via immobilization of PAR probe. HMS-TMAC-PAR has some important advantages as a solid-state colorimetric sensor(13) .In the present paper, a simple, selective and sensitive method is proposed for the vanadium determination at very low concentrations. 2. Experimental 2.1.Reagents and materials Tetraethylorthosilicate (TEOS) 98% (M = 208.33, d = 0.934 g/mL) were purchased from Sigmaââ¬âAldrich (Germany). dodecylamine (DDA) 98% (M = 185.36) was purchased from Merck, Germany. TMAC (50% methanol solution) was purchased from ABCR, Germany. PAR was purchased from Sigmaââ¬âAldrich (Germany) .Ethanol and toluene was purchased from Merck .All materials were of analytical reagent (AR) grade and used without further purification. 2.2. Apparatus and instruments The XRD experiments were performed by a APD2000 diffractometer using Cu K_ radiation over the range of 1.54Aà ¢-à ¦.FTIR spectra of the samples were recorded in mid IR (400-4000 cmâËâ1) region on a PERKIN EL MER65 spectrometer, using KBr pellet technique. UVââ¬âvis spectra were measured on a HACH DR -5000 spectrophotometer. In order to measure the pH value a HACH SENSION1 digital pH meter was used . 2.3.Synthesis of hexagonal mesoporous silica Synthesis of hexagonal mesoporous silica was achieved by dissolve DDA (200 mg) in a mixed solvent of water (0.28 L) and ethanol (0.19 L), after that the addition of TEOS (0.0112 L). The pH value of the solution was adjusted to 9ââ¬â11 with HCl. The finishing gel was stirred continually at room temperature for 18 h, and The product was filtered, washed by abundant distilled water, air-dried in an oven at 100à ¢-à ¦C.and then was accomplished by calcinations at 640à ¢-à ¦C for 4 h in air to remove the organic template. 2.4. Fabrication of HMS-TMAC-PAR Anhydrous toluene containing TMAC and HMS was refluxed for 18 h under an N2 atmosphere. The reaction mixture was washed thoroughly with ethanol and water to remove unreacted TMAC and then material was dried in an oven at 65 à ¢-à ¦C for 12 h to obtain HMS-TMAC. The immobilization of PAR on HMS-TMAC was performed by the addition of 0.6 g HMS-TMAC solid to PAR solution (93 Ãâ" 10âËâ6 M, 180 mL) in stirring for 3 h. it was washed with water to remove unreacted PAR. The material was dried in a vacuum oven at 65 à °C overnight and then ground to fine powder. The synthetic routes of HMS-TMAC-PAR were illustrated in Scheme 1. Scheme 1. HMS-TMAC-PAR 2.5.Detection procedure Batch and column processes were employed to study the detection of vanadium from aqueous solutions with HMS-TMAC- PAR. Concentration of stock solutions of vanadium (V) (1000.00 à µg ml-1.) Prepared by dissolving 2.2965g ammonium metavanadate (99.99% Merck) in 1000ml of 5% hydrochloric acid solution. The suspension solutions of HMS-TMACPAR (0.5 g LâËâ1) were prepared in aqueous solution at different pH values, which were adjusted with 0.2 M NaOH or 0.2 M HCl. Every time a 2 mL suspension solution of HMS-TMAC-PAR was filled in a 1 cm quartz cell and various stock solutions of cations were added into the quartz cell gradually by using a micro-syringe. Standard and blank solutions were prepared, in all the experiments in the same way as those samples. The linear working range for measurements was (y = 0.005x + 0.015, R2 = 0.990). The vanadium was estimated qualitatively using naked-eye colorimetric assessment and it was detected quantitatively using UVââ¬âvis reflectance spectrometry at 510 nm. 3.Results and discussion 3.1.Characteristics of HMS-TMAC-PAR The XRD patterns of samples are displayed in Fig. 1. The XRD measurements were employed in order to study the mesoporous structure of the supports. the patterns have a single low-angle diffraction peak at about 2 à ¸ =1.9à ¢-à ¦ for HMS and HMS-TMAC- PAR. but, the intensities of the peak of sample HMS-TMAC- PAR decrease, suggestive of that the mesoporous structure of sample HMS-TMAC- PAR. happen to fewer uniform ahead the foreword of the organic molecules interested in HMS(13). Figure 1. XRD patterns of HMS and HMS-TMAC- PAR. FT-IR spectra of HMS-TMAC-PAR is shown in Fig. 2. The HMS-TMAC-PAR sample show the characteristic Si- O- Si bands associated by the shape of a condensed silica network that be present at 1091, 965, 799 and 459 cmâËâ1. The findings revealed that the mesoporous silica (HMS) has been grafted via TMAC organic molecules(13). Fig. 1. FT-IR spectra of (a) HMS, and (b) HMS-TMAC-PAR. 3.2.Calibration graph The effects of various factors such as pH, reaction time, amount of material needed, and the presence of various concentration of vanadium were studied to optimize the conditions for quick visual detection of vanadium. Fig..3represents the absorbance of HMS-TMAC-PAR at 510 nm against vanadium concentrations and shows a linear correlation in the range from 40 to 500 ppb with a correlation coefficient of 0.99 . The nonlinear nature of the curve at higher concentrations is due to saturation effects. Fig.3.Calibration curves of the absorbance of HMS-TMAC-PAR with different concentrationsà of vanadium at pH 12.0 at 510 nm. The detection limit of HMS-TMAC- PAR for vanadium was also tested. Fig. 3 represents the absorbance of HMS-TMAC-PAR at 510 nm against vanadium concentrations and a good linearity relationship was gained in the range of 40 to 500 ppb with a correlation coefficient of 0.99. The spectrometer detection limit (DL) of vanadium using HMS-TMAC-PAR was estimated from the linear part of the calibration plot, according to the Eq. (1) DL = (1) where k is a factor equal to 3, m is the slope of the calibration graph in the lin-ear range, and Sb is the standard deviation for the blank. Here, The accuracy and precision of the method were tested by five successive measurements using a standard solution of 200ppb of vanadium. The resultant DL value is 0.88ppb. 3.3. Effect of the pH In order to determine the pH effect on the detection capacity of HMS-TMAC- PAR in batch experiments, solutions were prepared at different pH levels ranging from 2, 7 and 10. The pH-dependence studies showed that the complexation of vanadium with HMS-TMAC- PAR is formed in a wide range of pH, from 2 to 10(Fig. 4), which is similar to the results reported by Gang Li et al(13) . Also displays that upon the addition of vanadium, the virtual maximum absorption at pH 10.0, which has been selected as the specific pH for detecting vanadium in aqueous solution using HMS -TMAC- PAR. Hence, the maximum color and spectrum development of [Vââ¬âHTP]n+ complexes were at a pH value of 10. Fig. 4. Effect of pH on absorbance at 510 nm in UVââ¬âvis spectra of HMS-TMAC-PAR (0.5 g LâËâ1 ) with vanadium 200ppb. 3.4. Effect of the reaction time Studies on the reaction time indicated that the kinetic time response of the Vââ¬âHTP complex formation was studied by constantly monitoring the absorption spectra .as shown in Fig. 5. After addition of 200ppb of vanadium, the absorbance increases rapidly within 90 s and in that case residue constant with time, so shows that the reaction has completed. . Therefore HMSTMAC- PAR had been can suplid rapid colorimetric detection. Fig. 5. Response time of HMS-TMAC-PAR (0.5 g LâËâ1, pH 12.0) with vanadium 200ppb the later addition of vanadium ions, the color change of the sensors as a function of time. The findings revealed that charge transfer among the vanadium and PR probe has been accomplished in a short time (30 s âⰠ¤ Response time âⰠ¥180s) caused by the aptitude of the nanostructured sensors with open, great, and identical pore architectures to let the able binding of vanadium ions with graft PR-probe. actually the high metal change, that is ion transport, and the similarity of the metalââ¬âligand binding were significantly affected by the structural morphology and geometry, as obviously evidence from the Response time value(14). 3.5. Effect of sensor amount Studies on the sensor amount (Fig. 6) indicated that In actual fact, porosity, high surface area of the HMS hexagonal materials are beneficial to permit high adsorption capability of the chromophore investigation in quick kinetic systems. The amount adsorbed of the probe have a important roul in making a significant ion-sensing system. but , results show that the nature of the ion-sensing system is also reliant on the amount of solid support-probe used. On the other hand, the PR probe concentration significantly led to better sensitivity of the chemo sensors. The results show that 0.5 gr of sensors was enough to monitor a respectable color separation between the blank and the sample even at low vanadium ion concentration. Fig. 6. Effect of HMS-TMAC-PAR sensor amounts with vanadium (200 ppb) at pH 10.0, 510 nm 3.6. Effect concentration of vanadium In order to evaluate the effect of initial vanadium concentration, The naked-eye detection is achieved at a concentration range of 40ââ¬â400 ppb using HMS-TMAC-PAR Fig.7. A considerable color change for HMS-TMAC-PAR is observed from yellow to purple with an increase in vanadium concentration Fig. 7. Color reaction of HMS-TMAC-PAR (0.5 g LâËâ1, pH 10.0) with various concentrations of vanadium conclusions A highly sensitive optical sensor for the visual detection of low concentrations of vanadium is designed by the immobilization of PAR on the functionalized HMS. The high sensitivity of the optical sensor could be caused by its high surface area and the uniform pore sizes and pore shapes of the mesoporous silica. Controlled experimental conditions also allowed naked-eye detection of vanadium ion concentration with detection limit as low as 0.88ppb In alkaline solutions .generally, HMS-TMAC-PAR provide strange sensitivity, reusability and fast colorimetric detection of heavy metal ions, particularly vanadium for track of heavy metal pollutants in the environmental samples. The findings revealed that it could be successfully used as a colorimetric optical sensor for the quantitative and qualitative detection of very low concentrations of vanadium in various samples.

Understanding the Ten Commandments :: Religion
The Ten Commandments have been a subject matter of a large amount of controversy. Several do not beyond doubt understand its significance. A number of people believe that it should not be practiced today whereas others have a strong conviction that it should be. Although these Ten Commandments have been a obscurity for society it is possible to understand its true meaning. To accomplish this we must understand the Ten Commandments origin. Of course, we need to understand their main purpose, where they are found, who they were for, and how they relate to us today. So that we can embark on our analysis of the Ten Commandments we ought to commence with their derivation. As we take a look the Ten Commandments can be found in the Bible, in Exodus chapter 20. There we determine the purpose of these Ten Commandments. When the Israelites are freed from Egypt by Jehovah or God, Jehovah gives Moses some six hundred laws for the Israelites to live by. The reason for these laws was so they can be reminded daily of being sinners. From Mountain Sinai, an angel of Jehovah conveyed orally the commandments, ten of which are most commonly known, located in Exodus 20: 1-17. Later on, Moses went up to Mountain Sinai to receive the Ten Commandments, written on two pieces of stone, and other commandments and instructions. These laws were a pact between Jehovah and his people. Using Moses as a mediator between them, he provided these laws that would guide them and protect them in every field of their lives. While they would maintain loyal and obedient to him, he would be by their side and use them to bless other nations to come. Sadly enough, as we continue to read in the bible, while Moses long forty day stay on the mountain, the people of Israel grew impatient and made a statue to worship. When Moses descended from the Mountain and saw the sight of idolatry, he destroyed the two pieces of stone with the Ten Commandments. Obviously, by their actions, the vast majority of the Israelites did not have trust or faith in Jehovah. As punishment, Jehovah obligated them to journey across the desert for forty years. However, better times did come subsequent to their blunder. Although today some do know the history of the Ten Commandments and know some information about it, they do not understand how it relates to them in current times.

Obsessive Compulsive Disorders, Obsessive Compulsive Spectrum Disorders, and the P.A.N.D.A.S. Conne :: Biology Essays Research Papers
Obsessive Compulsive Disorders, Obsessive Compulsive Spectrum Disorders, and the P.A.N.D.A.S. Connection As someone who's been plagued by an Obsessive Compulsive Spectrum Disorder since childhood, I can say it seems hopeless at times. For so long a sufferer feels that what they have isn't a legitimate ailment and that he is alone in his battle. Thankfully, in recent years, more and more research is being done on Obsessive Compulsive Disorders, and more answers are being found. Obsessive Compulsive Disorders are the fourth most common psychiatric diagnosis. Sometimes the onset of symptoms is sudden, but more often than not it is a gradual progression. Precipitating events that could spur the onset of an Obsessive Compulsive Disorder can include emotional stress (domestic or job-related), increased levels of responsibility, health problems, and bereavement. According to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, "the essential features of an Obsessive Compulsive Disorder are recurrent obsession or compulsions that are severe enough to be time consuming (i.e.: they take more than an hour per day) or cause marked distress or significant impairment. At some point during the course of the disorder, the person has recognized the obsessions or compulsions are excessive or unreasonable. It's important to note that this is difficult concerning children because children tend to not realize that their compulsions are excessive or unreaso nable while adults do ((1) .). People develop compulsions by trying to ignore thoughts or impulses, or by trying to neutralize them with other thoughts or actions. Compulsions are mental acts, and include repeating words, ordering things, hand washing, and various other motions. The goal of these compulsions is to prevent or reduce anxiety. Because Selective Serotonin Reuptake Inhibitors (SSRI's) such as Prozac, Luvox, Zoloft, and Paxil are effective in controlling Obsessive Compulsive Disorders, it's believed that serotonin regulation is a part of the cause of OCD. Serotonin is a very important chemical messenger in the brain, and plays a role in a person's mood, aggression, impulse control, sleep, appetite, body temperature, and pain. Brain imaging studies have depicted various abnormalities in parts of the brains of Obsessive Compulsive Disorder sufferers. These parts include the caudate nucleus, the basil ganglia, the thalamus, orbital cortex, and cingulated gyrus. Disorders that have the obsessive compulsive symptoms of intrusive, repetitive behaviors are often called OC Spectrum Disorders. Amongst these include Trichotillomania, Monosyruptomatic Hypochondriasis, Body Dismorphic Disorder, and some eating disorders.
