Are historians probably the least recognized movers and shakers of the society?

Historians are probably the least recognized movers and shakers of the society. As historians, it is always about their works and not about them. Well, there may be quiet a few historians who are popular, but again, they became famous because other historians chose to study and write about them. Behind every historical figure, behind every icon, is a historian. So for me, this is a chance to shine the light on these people, a good way to return the favor. Going back to the discussion question, my affinity is more towards psychohistory.For me, this is probably the most challenging one, since it goes beyond the available information for a certain topic or person (385, Breisach). It involves reading between the lines, of how an event in a person’s life, say in his childhood, may influence his service as the president of a nation. It goes beyond gathering data and piecing them together in something that could be easily understood by others. It is not limited to a single person or event, as it could also be applied to a group of people at a certain time.Psychohistory deals with much more interesting works aside from the endless researches and investigations usually conducted by historians. Response 1: From your response, I can see that your deep interest with literature and art somehow influenced your affinity to Romantic historiography. I agree with what you said about how Romantic historians wanted to hold the reader’s attention, and it is because the topics included in this aspect are anything but the ordinary, thus keeping the focus and the attention of those studying Romantic history. This is very broad, and I doubt that you’ll run out of anything interesting.Response 2: I admire the set of criteria for a historian that you have laid down, but I think it’s rather hard to follow. First and foremost, just choosing on a subject would still be subject to bias. Why would do a historian choose to write about the Greeks and not about the Ro mans? There is a big difference between a historian and a news reporter. The biases that a historian possess is what makes history interesting. Despite all the facts about a topic, there is still a hint of uncertainty in it. For me, the need to clarify and verify facts about our history is what defines historians. Response 3:I agree with you that psychohistory is indeed very interesting. In fact, it is also my choice in this discussion. From your response, you focused on collective psyche, which for me is a defining aspect of psychohistory. It is usually the leaders who are subjected to this, since they are prominent and their actions affect a larger scale. However, I think that this could also be done to anyone else worth studying, since it involves informed interpretation. All you need to have is a basis for that interpretation, and that entails gathering data about the subject, something which is common to all historians.

Starbucks Summary

This is to recommend that Struck to increasing the power of expand the international markets especially the countries that Struck has not been launched yet in order to gain more global market share thus generate more sales. Struck also need to reduce the power of expand domestic markets since the market in the US is approaching saturation and the marketing- warming expansion techniques has caused cannibalize existing store sales.Based on my analyzes on the case Planet Struck (A), Struck Coffee remains a leader in the coffee business in the world for a long time because the perceived premium product's cachet that they are offering customer something so far superior than customers' expectations and their ubiquitous positioning strategy that providing ready access to customer foot traffic. These are the biggest strengths of Struck. Based on its existing successful del, Struck has indicated continuing increased gross operating income and operating income. See Appendix#l ) This huge succe ss offers Struck more resources to expand its international market such as capital, existing business model, successful previous experiences and expert management team. At present, it is the great time for Struck to expand its international market, since the domestic market is approaching saturation. Even the marketing-swarming expansion techniques prevented competitor entry to the rake and helped Struck built strong brand awareness and recognition, it leads to downward trend in sales per store.As an illustration, between 1 995 and 1 998, Struck had averaged $0. 69 million sales per store per year but until 2002, the sales has been decreased to $0. 559 million per store. This data reflected the domestic market has approached the saturation. However there is still an opportunity to increasing the globally market share, since in year 2002, there are total of 4574 domestic stores but the total number of international stores are only 131 2, which is only quarter of the number of domesti c stores. See Appendix #4) Therefore, expanding international markets would lead to increasing the globally market share thus generate more sales and also will help the company to achieving its objective which is establish Struck as the most recognized and respected brand in the world. Struck has a pretty strong brand image to many of its customers as a â€Å"third place† where is a place between work and home that people can escape, reflect, read, chat and listen.This niche positioning strategy has differentiated Struck from its competitors and this strategy has also become to Struck strongest competitive advantage that provided customers an atmosphere of both warmth and comfort. In conclusion, the main plan of action right now should be to focus on expanding international market instead of domestic markets. Thus the global market share will be increased if the marketing strategy is executed correctly and cooperated with right partner.

Article In Business Example

Article In Business Ryanair warns fares will rise This article published in The Guardian discusses about Ryanair’s warning to shoot its fare up in the near future. Thisrise in fare would have to be made to meet the company’s targets. All such measures are been taken by the company to increase its profits in the upcoming years. This sudden move to increase the fares and profit is because the company posted an approximate loss of â‚ ¬11 million in the third quarter of 2010. Although the company has been a successful airline service provider recognized as one of the best in the world, it has recently been criticized by some critics along with some of its customers. The basic reason for Ryanair’s success was their ability to cope with their costs which they offered to their customers in the form of low fares, such fares were really low when compared to other airline service providers. Ryanair’s great tendency to innovate always led them to reduce their costs and increase the q uality of their service. Innovation had always been a main factor that led Ryanair to open new dimensions in the airline industry. The strategy followed by Ryanair to reduce their costs was to have low emission aircrafts such as Boeing 737; these aircrafts were also fuel efficient hence they helped Ryanair to have better control over their fuel costs even in the era when fuel costs increased drastically. Such better quality and low cost led Ryanair to be pronounced as the most profitable airline in the world by an Air Transport World Magazine. The article discussed that the company had good prospect as one of its competitors, Germany’s Blue Wings, had left the market and had created a greater scope for Ryanair to capture a much larger market share in the upcoming future. Although according to the company’s Chief Financial Officer, the company might increase its fares in the future, Michael O’Leary, the chief executive of Ryanair was of the view that the company would heavily focus on cutting its costs much more. Besides this statement, he also pointed towards the better and productive performance of the company and increased gain in the market share of the company in area such as Spain, Scandinavia, etc. Because of this news, there was a sudden rise of 5 % in the company’s share in the Dublin market. This article lead to an increase in the share price for Ryanair but this can also signal alarms for its customers as there may be some rise in the fares charged by the company. The positive thing derived from this article would be to favor the shareholders of the company, who would enjoy better profits in the following years to come.

A paper to explain the importance of the Pacing Guide Research

A to explain the importance of the Pacing Guide - Research Paper Example In addition, parents as well as guardians may use the pacing guides to know what their children are pursuing at a certain period of time and these study materials comply with the grade level indicators and State Standards. Moreover, these helpful pacing guides provide both students and teachers with a guideline for assessing instructions. Another importance of a pacing guide is that they help teachers to mark the essential concepts that they should teach and the amount of time they should devote for completion of one topic (Goldsmith, 2010). Pacing guides are also used by teachers to allocate time for assessments and instructions. Some of the pacing guides also provide teachers with assessment calendar as well as enabling them to effectively outline the curriculum to be used to cover all the skills in a certain assessment. Another important feature with pacing guides is allowing professional learning developments in communities of a certain district (Saricks, 2009). Since teachers in a certain district use similar teaching material, they discuss and come up with effective strategies for a certain assessment unity. Goldsmith, J. (2010). Pacing and time allocation at the micro-and meso-level within the class hour: Why pacing is important, how to study it, and what it implies for individual lesson planning.

Is Feminism Still Necessary Within the United States Assignment

Is Feminism Still Necessary Within the United States - Assignment Example The paper will first consider what those who support a further form of feminism might say with regards to the prospect that the future holds and what extent need may still exist for feminism. Once this has been discussed with a level of depth and clarity, the analysis will then move on to some of the reasons for why such an approach necessarily guarantees that there will be perennial requirements for further feminism within the United States and elsewhere. Some of these requirements are concentric upon the religious mores that are currently exhibited within the current system; whereas others are merely an example of history and the cultural determinism that has helped to define the United States in the way that it is. Finally, the last portion of the analysis will argue the position of the author with relation to this issue.  Those that put forward the belief that further feminism is required in the United States generally point to sociological/demographic data. As such, this data helps to prove the point that a mere 60 years ago the presence of women in the workforce and their integration into distinct segments of society was practically unheard of. Naturally, the greatest liberation that was the culmination of this was the widespread availability of cheap contraceptives in the form of birth control pills. As history has proven, societies in which women have control over their biological clocks have the ability to pursue higher education, careers, and personal fulfillment without being saddled with the responsibilities of the family prior to the time in which they would otherwise choose to do so. Moreover, as a function of these recent development in the rights of women, specifically within the United States, but increasingly in other parts of the developed and developing world as well, proponents of such a point of views to the fact that is merely only a matter of time and human societal evolution until a true and complete understanding of global feminism i s realized.   As such, it is not reasonable to assume that the greatest achievements of parity have yet been accomplished within the United States.   For instance, a female’s pay is still substantially lower than that of a similarly trained and/or talented male.

THE RELATIONSHIP BETWEEN CRIMES RATES AND GUN OWNERSHIP IN SAUDI Research Paper

THE RELATIONSHIP BETWEEN CRIMES RATES AND GUN OWNERSHIP IN SAUDI ARABIA - Research Paper Example udi Arabia is the reserves of Oil that the country possesses in a huge quantity, being the world’s second largest country in terms of reserves of oil. Saudi Arabia is a country that does not have a separate code of law because it follows the Islamic Shariah laws which are the strict code of conduct being followed in the country. Saudi Arab basically lies in a desert zone, covering about 80% of the Arabian Peninsula (Abir 1993) The culture of Saudi Arabia is strictly Islamic where there is a large majority of Muslims. Everyone is bound to pray 5 times a day, even forcefully if found on streets near mosques not praying. Non Islamic practices such as consumption of Alcohol are strictly forbidden and it is compulsory for women to wear ‘burqa/hijaab’ while they are not at homes. It is a regular practice for men to marry multiple times, more than twice and men are generally more dominant in Saudi Arabia. Capital punishment in Saudi Arabia is frequently observed and a few years back from now, it was quite famous that during prayer times, when all the shops in streets are open while people say their prayers, nobody dares to get involved in theft. In recent years however, the crime rate has increased in the country, the reasons for which will be observed later. Punishments such as amputation, beheading, lashing and death are imposed by courts of Saudi Arabia depending on crimes including murder, theft , rape, robbery or adultery. Saudi Arabia faces many social issues such as corruption, unemployment and extremism. The confusion lies in the fact that Saudi Arabia wants to become a modern country but does not want to leave its traditional Islamic culture and practices at the same time. Additionally, Saudi Arabia is also accused of financing terrorist operations throughout the world in the name of Jihad (Sacrifice for saving Islam and for God). Moreover, the National Society for Human Rights which is a human rights organization operating in and funded by Saudi Arabia

Reading Adam Smith in the 21st Century Essay Example | Topics and Well Written Essays - 1500 words

Reading Adam Smith in the 21st Century - Essay Example Adam Smith was born in 1723 in a village called Kirkcaldy in Scotland. His family was influential; his father the elder Adam Smith held several important positions at the time of his death in 1723. At the age of fourteen Smith entered Glasgow College where his teachers included among other famous men, the great Frances Hutcheson. Smith was to discover and foster his talents and abilities in this college. John Rae (1895) in his biography of Smith titled The Life of Adam Smith stated that it was Hutcheson and later Hume who seem to have had the most influence on Smith. Hutcheson was an engaging and powerful speaker who animated Smith's mind. Hutcheson was one of a new breed of philosophers who were perceived to be radical in their thoughts and beliefs by the theological conservatives. In fact Rae credited Hutcheson with the development of Smith's ideas on natural liberty, the value of labor as the source of wealth etc. Soon after on a Snell scholarship Smith left for Oxford in 1740. In a strong contrast to Glasgow, the atmosphere at Oxford was lax and lackadaisical. Smith found that Oxford, being wealthy through endowments had become inept as a result. Lecturers had no incentive to perform and the students were pretty much left to themselves to learn on their own. However in the six years he spent there he kept himself busy mainly by reading the ancient Greek and Latin classics. After graduating, Smith went back to Scotland. In 1750 he was appointed Professor of Logic at Glasgow College and a short while later shifted to the Chair of Moral Philosophy. It was while he was Professor of Moral Philosophy at Glasgow College that he wrote The Theory of Moral Sentiments in 1759, the book that he himself considered to be his finest accomplishment. The Theory of Moral Sentiments grounds sympathy as the basis of social relationships and in the larger sense of society itself. The book is believed to share Smith's own belief in Stoicism as well as the influence of Hutcheson. The Theory of Moral Sentiments demonstrates that Stoicism was an important part of the mental make-up of Smith. Smith basically combined the stoic precept of self command with the Christian idea of benevolence. Much like the Stoics, Smith too prefigured the social bond among humans in terms of "sympathy" while the Stoic idea of world citizenship and self-command portend the role of Smith's impartial spectator (p.10). The Theory of Moral Sentiments tries to understand the function of moral behavior in society. Smith departed from Hutcheson and other philosophers in that tradition like Shaftesbury and Hume by defining motive as an essential element of moral behavior. Hutcheson had rejected that motive had anything to do with morality and instead claimed that man possessed a certain innate sense that propelled him to be moral. Smith makes motive an integral part of moral behavior arguing that people often look to the motives of a benefactor before bestowing their approval of a beneficent action. An act of kindness performed unknowingly without the motive to do good to anyone does not bring the same admiration and esteem that result when it is deemed that the action was performed with the knowledge that it would

Why is the Oil Industry and Corruption so closely linked Research Paper

Why is the Oil Industry and Corruption so closely linked - Research Paper Example It has been alleged that these TNC and The MNC are always on the move to increase their market profits and to an exceptional gain competitive advantages, this they achieve by indulgence in unscrupulous activities like money laundering, corruption, bribery and many other malpractices showing little appreciation for social requisites and laws. These corporations have covered their community relations by hiding under the claims of being socially responsible and of the reputable ethical conduct, although the evidence in this paper proves the otherwise. The present decade is however no exception bearing in mind the tendency in the relationship in between these corporations and the civil society actors, the emergence of collaborative relationships, only benefit the business’s image than it does to the community society, it is however, unfortunate that even the media and the already published literature seldom examines greedy practices of corporations despite the fact that, the pract ices impact negatively on the stakeholders. This has resulted into several ethical questions on the real intentions and practices of the leaders in these corporations, the efficacy of their public association’s campaigns and the strategic location of the various civil society actors. This paper answers various arising questions by giving a thorough examination of the activities of an oil corporation, Shell, and looking into its relationship with communities in Niger Delta, Nigeria, it also looks into loop holes existing corporate anti corruption and acts, it goes ahead to show that companies really engaged in corruption and various malicious money laundering claiming that it is part of them being responsible social conduct. Purposely paying a close attention to Shell’s corporate social responsibility (CSR) initiatives which were aimed at developing the communities of Niger Delta. The case study is founded on both secondary and primary sources that included field observ ations and interviews with some key executive members of the corporation, local communities, government officials and some senior members of the oil companies in the Nigeria’s Niger Delta area. The paper argues that the corporations have made use of the political elite in the country to expand their global earnings and to gain competitive advantages by unscrupulous means such as bribery and other inducements to attain some government contracts in Niger Delta area, Nigeria. 1. Introduction A sector of business which makes firm claims to business ethics, Transparency, stakeholder’s rights, Employee rights, Corruption and human rights and codes of practice can safely be said to be the oil sector (Lawan 98). Oil Corporations are very dynamic and have leadership roles in coming up with allowable corporate practices and key acceptable codes of conduct in various places of work and involvement with various facets of the community. The involvement of Shell, in the famous Volun tary Principles on Security, United Nations’ Global Compact, and Human Rights, are just some instances. Its contribution towards the development programmers in construction, education, Transport and health, etc, cannot be underestimated. In spite of these contributions and achievements to the society, like many other corporations it has targeted of many negative or anti-corporate campaigns, such as corruption in the past few decades. Most civil society actors, including the anticorruption, anti-capitalists and anti-corporate

Cost Benefit Essay Example | Topics and Well Written Essays - 250 words

Cost Benefit - Essay Example In the case stated, reducing expenditures compared to raising taxes have various repercussions even if both course of action are unpopular. Reducing expenditures meant foregoing the opportunity to serve the people and to provide services that could potentially prevent future problems. For example, health care programs could make the population healthier with an implication of lesser health cost in the future. In the case of education, reducing its expenditures may not be immediately felt but it will undermine the country’s competitiveness in the future because it would mean having less educated workforce. Raising taxes however is unpopular. But it will enable the government to fund its social services such as health and education. Excessive taxation however invites social unrest that could defeat its intent to provide services to the people. The repercussion of high taxation is political as policy makers may lose public support and will no longer win in elections. Ultimately, governments have to balance between increasing taxes and reducing social services. Ideally, taxes should be low and social services should be high but that would not be possible since social services is expenditure and it needs income through taxes to fund it. This explains why social services and taxation should be

Stereotype, whether positive or negative, are harmful Essay Example for Free

Stereotype, whether positive or negative, are harmful Essay In todays world, many people has different stereotype about somebody. There are positive and negative, but both of them are harmful to people. People always stereotype about other people who they dont fully know them. In Archbishop Riordan High School, most of the students think Chinese students are very good at math. In fact, some of the Chinese students are very bad at math. This maybe harmful to those Chinese students who did badly at math, because it makes them think they are different to a normal Chinese student. It shows not only negative stereotype will be harmful to people but also positive stereotype will cause harmful to people. Some writer make positive and negative on their essay. In I Want a Wife, Judy Brady is a female who stands on a male view about getting a wife. She discuss about what kinds of wife a male would want to get. She mentions I want a wife who will take care of my physical needs, I want a wife who will take care of the details of my social life, and I want a wife who is sensitive to my sexual needs. (P. 37) She thinks male usually make both positive and negative stereotype about female. In this essay, male think a female has to care everything about his husband, take care of the children, and stay home cleaning. In fact, females are getting more independents today. They want to get money by themselves and dont want to stay home take care of everything. Even though it is positive stereotype about a female who can take care of everything that happens at home, but it is still making negative stereotype about a female cant work other than staying home. This will cause harmful to a female who is going to marry a person that stereotype female like the writer did. Another writer that writes essay about stereotype is Brent staples. He writes about his experiences of racism or stereotype in Black Men and Public Space. He mentions At dark, shadowy intersection, I could cross in front of a car stopped at a traffic light and elicit the thunk, thunk, thunk, thunk of the driver-black, white, male, or female- hammering down the door locks. (P. 2) This is showing people stereotype about the writer. They think he may take their car or do something bad to them, so they lock the door locks. Another time is One day, rushing into the office of a magazine I was writing for with a deadline story in hand, I was mistaken for a burglar. The office manager called security and, with an ad hoc posse, pursued me through the labyrinthine halls, nearly to my editors door. (P. 3) The office manager has stereotype the writer as a burglar even though he is working at the office of a magazine. This might make the writer feel harmful, because people make negative stereotype about him as a bad person, like a burglar. There is a stereotype called cultural stereotype. Judith Ortiz Cofer writes an essay called The Myth of the Latin woman which is about cultural stereotype. This essay is about a Latin girl facing different culture people. She remembers what happens to her at her first dance. I remember the boy who took me to my first formal dance leaning over to plant a sloppy, over-eager kiss painfully on my mouth; when I didnt respond with sufficient passion, he remarked resentfully: I thought you Latin girls were supposed to mature early, (P. 106) The boy mentions about Latin girls were suppose to mature early, which shows this boy is making a positive cultural stereotyping about the writer. In fact, the writer didnt grow into womanhood yet and this might cause harm to the writers heart. I Want a Wife, Black Men and Public Space and The Myth of the Latin Woman had proved example of both positive and negative stereotype. Some people think it is fine to make positive stereotype about other people. In fact, these three essays had proved that not only negative stereotype will cause harmful to people, but also positive stereotype will cause harmful to people. Hopefully, people will stop causing harmful to other people by stop stereotyping about other.

Europeanization Case Essay Example for Free

Europeanization Case Essay INTRODUCTION A number of related phenomena and changing patterns have been referred as Europeanization by many experts and professionals in their different studies and researches in this field. Outside of the social sciences, when a European continental identity grows, it is commonly referred as the definition of the Europeanization.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In this case, national identities, countries, and polities in the European continent are regarded as growing under the banner of Europeanization. When the organizational logic of national politics allows the political and economic dynamics of the European Union to become its part, it might also refer as the process of Europeanization. Policy-making in this governmental judgment has also been included in the definition of the Europeanization.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Within a European context, national, regional, and other identities are re-defined by the leading of European governance at its various levels by the institutional interaction of policy actors, as posits by a more nuanced analysis. In this regard, opposition is not usually seen among the multiple levels of governance in the continent of Europe.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In this way, a stronger, strengthened, and the United States is found to be gathering collectively under the name of Europeanization. In the result, identification of these European states is being done collectively, rather than identifying them as German, French, etc, as it was done in the past by different European states in the continent   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Institutions of Europe consist of an obvious area of change in them particularly. In addition, the growth of the European Union has also been changed during the process of Europeanization. In this case, the European Central Bank has been provided with the monetary policy of various nations that have been using the euro as their national currency.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In this regard, Spain is one of the European countries that have gone through the process of Europeanization since many years, and a full European government has been eventually lead by the continuing process of Europeanization in the country. In this study, we will try to understand the process of Europeanization from the case study of Spain. Government, politics, and culture of the Spain will be focused, in order to understand the significance of Europeanization, as well as, the European Union in the continent of Europe.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   An example of pacific democratization has been underlined by the establishment of democratic model, as well as, after the Franco’s death during the transition of the Spain. A unique example has been highlighted by the abovementioned in this regard. The devolution of competencies concerning the different regions has been achieved by the first steps of autonomous communities’ concept and system in the Spain.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In the last years, appearance of regional statutes has been done in different reforms due to high extent of strong questioning than ever before. In one’s perception, more competencies and decentralization have being claimed by the regional powers. Almost independent projects have been covered by these reforms. The Spanish parliament rejected Ibarretxe’s Plan on February 2005.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Some of the main points of the new statutes are the equality between autonomous communities and countries, empowering the self-government, and nationality in the region. As the central-state in shape of unique actor in international matters has been recognized by the Spanish constitution only, one of the most problematic aspects has been the direct international representation of the Spain in the world.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In this sense, some of the aspects that conflict between the regional forces and central state are the implementation and decision-making processes of the European Union. The autonomous communities have been influenced by one of the most influential factors with the help of the regional policy of the European level, even after twenty years of association with the European Union by the Spain. EUROPEAN INTEGRATION   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The barriers of national state of Spain have been over gone by the integration process of Europeanization in the continent. In 1988, the structural funds were reformed during the process. In this process, the commission, the concerned member states, and the recognized and designated competent authorities have consulted closely, in order to define the term partnership. In this case, the problems and priorities of targeted regions were familiarizing with the local, as well as, the regional actors, in order to create the efficiency of the regional policy through the abovementioned local and regional involvement by an attempt of the partnership principle. In this case, the regions were given the chance and opportunities for the first time to create their own regional policy, rather than following one in the region. From the beginning of the text, this point was reinforced by the Treaty of Maastricht. According to this treaty, the citizens of the continent were encouraged to become closer, in order to make effective decisions in the region, and to recognize the objective based on united Europe, rather than for individual states. Therefore, the structures would not be left equally in the European Union by the expansion of actors in it. In this case, private spheres were also included along with the regional actors during the expansion. In the result, the complex system of transnational decision-making has been integrated in the continent of the Europe. In this regard, the wider framework of European policy system has been provided to these regional and national states, in order to defend and represent their interest in the continent. The process of the combination of different European states with the Spain has been referred as the sandwich model by some authors. However, the Spain has faced the lost of territorial sovereignty, but in the European level, its regional position has been strengthened and revaluated during the process of Europeanization. In the European level, the empowerment of regional actors has not only been faced by the Spanish national state, however, it has also been faced within its own barriers. In other words, the territorial space and the functional space have been facing a friction in the Spanish state. Newly functional bonds have been replaced by the long existing territorial lies in the region. In the Spain, the concept of government has been widened with that of the governance due to this continuous process of Europeanization in the region. At the same time, the role of national governments, and particularly Spain, has been strengthened by the regional policy of the European Union in the region. In this regard, the policy-making and decision-making opportunities have been given to the Spanish national state by the European Union. PARTICIPATION OF AUTONOMOUS COMMUNITIES IN EUROPEANIZATION The process of Europeanization has been made difficult by the weak territorial framework, as well as, the institutions. In the last twenty years, an initial competitive adaptive strategy has been replaced by the autonomous communities, in which, each competencies against the central state has been preserved by each region. Some of the examples of this moving from an initial strategy are the new framework of 2004, which were created in the CARCE, as well as, the Inter-ministerial Conference on the European Affairs, which was held in the year 1988. The transfer of both national and regional competencies has been allowed by the Spanish constitution, as well as, its legal framework to the European level. In this regard, the consent of the autonomous communities has not been required during the transformation. In this case, the regional powers and central state have gone through a feeling of friction between them. At the beginning of the Europeanization process, the losing of competencies was not concerned by the autonomous competencies in their important fields of agriculture, fishery, industry, etc. Even they felt that competencies were regained by the central state by the utilization of transfer power, and by implementing community law to the autonomous communities. The central administration and regional governments came under the competitive situation due to the abovementioned reason, which occurred during the 80s, as well as, in the beginning of 90s in region. Therefore, the abovementioned are some of the factors that changed the situation of Spain during the process of Europeanization in the region, and which changed the perception of local, as well as, the regional states in the continent.    AGREEMENT OF 1985   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In 1985, the Spain accessed to the European Council, before which, European policy-making was analyzed, in order to find the coordination and cooperation inter-governmentally in the central regions. In the implementation of European legal acts, the Spanish regions were tried to participate by the regulation of proposal of the central administration.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In relation with the Spanish stage, the distribution of responsibilities was proposed by the Spanish government, where the European policies were transposed by the central state, while the practice was put on by the autonomous communities. The project of agreement of 1985 was not found to be so specific during the decision-making process in the European level. However, this agreement is considered as one of the important aspects during the transformation of Spanish government into a unified European state. SPANISH GOVERNMENT’S SECOND PROPOSAL   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   After the rejection of the first proposal in 1985, second proposal was given by the Spanish legal framework in the year 1986. In this proposal, some considerations of the first proposal that was failed were taken by the Spanish central-administration. Domestic policy-making was proposed by the Spain, in order to distribute the responsibilities effectively in the region.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   On the decision making stage, the regional governments were provided with all European governments as per the proposal of Spanish government. The competencies, their interests, and their related information were also provided in this second proposal of the Spain. Interestingly, the idea of an inter-autonomous coordination body was the most interesting and fascinating point of the second proposal of the Spain, which was affected the proud culture of the Spain, which was usually depended on its domestic policies, rather than depending on the responsibilities and actions of the regional states in the region. SPANISH GOVERNMENT’S THIRD PROPOSAL   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The conditions of the 1986 project were kept similar in the third draft of the Spanish government regarding the European policies in the Spain, as well as, in the other regional states. However, the participation of autonomous communities changed in the level of decision-making. In this proposal, the idea of an inter-autonomous coordinating body was dropped by the Spain, and a possible forum was seen as the Sectarian Conferences. However, new inter-governmental coordination mechanism was allowed for the discussion in this third proposal of the Spain. INTERGOVERNMENTAL AGREEMENTS   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   After the rejection of all the three proposals of the Spanish government regarding the participation of autonomous communities in the implementation of the European policies, an institutionalized dialogue was created by partial agreements, known as the intergovernmental agreements. Therefore, the Inter-ministerial Conference on the European Affairs was created on December 1988. The three basic principles were formulated in the second session of this conference in the year 1989.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   According to these principles, the central state belong the exclusive competence regarding its foreign relations with the regional bodies of the region. Secondly, the internal distribution of the competencies must not be affected by the accession of Spanish government in the European Union. Thirdly, the second session formulated that the legal framework of the Spanish Constitution should be followed by the central state during the exercise of their competencies. PROCEDURAL FRAMEWORK IN 1994 Finally, intrastate participation of autonomous communities was provided by a comprehensive agreement of the Spanish government, the European Union policies were implemented in the decision making level as per the agreement. The principle of unity in external representation was respected by the new agreement. In this way, the autonomous participation was allowed in their different fields of agriculture, environment, employment, fishery, health, social policies, education, etc. In addition, youth and culture were also given a significance importance, in order to keep their significant magnitude in the region. CONCLUSION In the Spanish recent history, the relation and act of the two processes that are, Europeanization, and decentralization have been observed parallel with each other. In the result, the problems of intrusion and conflict have been caused most of the time between the regional and central-state governments. In the last years, one of the most important questions have been faced by the European Union regarding its integration process, which is the question of democracy, as the reflection of France and Netherlands have been observed in the shape of their constitutional referendums. Conclusively, the process of Europeanization can be understood interestingly by the example of the Spanish reality in asymmetrical states. The governance in European Union level and its work can be extrapolated in this sense. Lastly, we have tried our best to define, understand, and discuss the meaning of Europeanization with the case study of Spain and its central state, as well as, their different proposals regarding the Europeanization in the region.                         Works Cited Robert Harmsen.

Reversible Photochromism: Effects and Applications

Reversible Photochromism: Effects and Applications 1. Introduction In this report I will be looking at the smart material property known as Reversible Photochromism. This property contains a range of chemicals that react to UV light. This report will explore a range of the effects of the compound, which will include a review of the applications of this property and the process that make them possible, by exploring the, Ring Process, method. This report will also include looking at general applications where Reversible Photochromism technology is being used and any future concepts, such as, smart materials/technology involving textiles, dyes and inks. Including existing products, such as, transition lenses, and how that technology can be used for greater achievements. 2. What is Photochromism? Photochromism is the reversible alteration of a chemical variety between two forms by the absorption of electromagnetic radiation, where the two forms have different absorption spectrum. This can be described as a reversible change of colour upon exposure to light. Where the current substance transforms into a different colour once exposed to UV light. Once the UV light is removed, the substance under goes a transformation into its original state. Interest in Photochromism was constant but limited until the 1940-1960 periods, which saw an increase of studies, particularly in the research groups of Hirshberg and Fischer in Israel. In 1950, Hirshberg suggested the term photochromism [from the Greek words: phos (light) and chroma (colour)] to describe the phenomenon. This is the name used today. The mechanism for Photochromism in plastic crystalline materials is shown below. (Closed Form) (Open Form) Photochromic colours/dyes are plastisol-based inks, which are off-white when not exposed to UV radiation. It gains colour when exposed to Sun light / UV light. The colour change is reversible, i.e., the colour will fade again and appear colour less or clear upon removal from UV light / sun light exposure. These inks are available in various colours; ranging from dark tones to bright pink. 3. How  are Photochromic Lenses Made? There is a vast range of different states Photochromism can be manipulated into. All of these states have extra compounds and particles. The most common Photochromic state is glass lenses. Photochromic lenses are lenses that darken on exposure to ultraviolet (UV) radiation. Once the UV is removed, for example by walking indoors, the lenses will slowly return to their clear state. Photochromic lenses may be made of glass, polycarbonate, or another plastic. The glass version of this type of lenses was first developed by Corning in the 1960s. More recently, plastic versions of these lenses have been commercialised. The first of these was the Photolite lens sold in the early 1980s. But the first commercially successful plastic Photochromic lens was introduced by Transitions Optical in 1991. The glass version of these lenses achieve their Photochromic properties through the embedding of microcrystalline silver halides (usually silver chloride), or molecules in a glass substrate. Plastic Photochromic lenses rely on organic Photochromic molecules to achieve the reversible darkening effect. The reason these lenses darken in sunlight but not indoors under artificial light, is that room light does not contain the UV found in sunlight. Transport windows also block UV so these lenses would darken less in a car. Lenses that darken in response to visible (rather than UV) light would avoid these issues, but they are not feasible for most applications. In order to respond to light, it is necessary to absorb it, thus the glass could not be made to be clear in its low-light state. This correctly implies Photochromic lenses are not entirely transparent; specifically they filter out UV light. This does not represent a problem, because the human eye does not see in the UV spectrum. With the Photochromic material dispersed in the glass substrate, the degree of darkening depends on the thickness of glass, which poses problems with variable-thickness lenses in prescription glasses. With plastic lenses, the material is normally embedded into the surface layer of the plastic. Typically, Photochromic lenses darken substantially in response to UV light in less than one minute, and then continue to darken very slightly. This can take 15 minutes. The lenses fade back to clear along a similar pattern. The lenses will begin to clear as soon as they are away from UV light, and will be noticeably lighter much quicker than the darkening process. However, it can take up to more than 20 minutes for the lenses to completely fade to their non-exposed state. Because Photochromic compounds fade back to their clear state by a thermal process, the higher the temperature, the less dark Photochromic lenses will be. This thermal effect is called temperature dependency and prevents these devices from achieving true sunglass darkness in very hot weather. In contrast, Photochromic lenses will get very dark in cold weather conditions; which makes them more suitable for snow skiers than sun worshippers while outside. Once inside, away from the triggering UV light, the cold lenses take longer to regain their clear colour than warm lenses. 4. The Chemical Compounds of Reversible Photochromism Photochromism can be manipulated into different states, liquids; gels, dyes and water like substance, and solids; thin plastic like films and pigment powders. The most common form of Photochromism is liquid dye. This dye is a clear substance that can be penetrated and manipulated into different forms. Dyes reversibly alter their colour upon exposure to ultraviolet sources. These chameleon-like dyes respond to natural solar irradiation as well as artificial sources such as 365 nanometer black light. When sunlight or ultraviolet (UV) radiation is applied, the Photochromic dye becomes excited and the molecular structure is changed allowing a colour to appear. When the stimulus (sunlight/UV radiation) is removed, the dye will return to a state of rest, which is its colourless form. Photochromic molecules are not reactive in their crystalline state and need to be dissolved in a solvent or polymer to function. A common feature of the Photochromic is a colourless isomer that contains a carbon-oxygen bond which dissociates with UV activation. The colourless isomer contains two localized pi systems that absorb only in the UV part of the spectrum. Hence, the molecule appears colourless. After the carbon-oxygen bond dissociates, the two pi systems change into a single delocalised pi system which absorbs in the visible part of the spectrum, causing colour formulation. The life of Photochromic material depends on the amount of Photochromic compound used, the stabilisers used and the material in which it is used. Generally, it is suggested that 0.1 gram per square foot be used to provide an adequate reservoir of Photochromic compound. The use of ultraviolet absorbers will also extend the life of the Photochromic, but will reduce the colour intensity. There are effectively two changes occurring simultaneously; a chemical change arises when the molecule is exposed to UV light that enables conjugation to take place throughout the molecule; a structural change also occurs to enable the overlap of molecules. Therefore, spatially, the molecules must be able to flatten out to allow this conjugation to take place. It is a fully reversible reaction so that when the light source is removed, the molecule returns to its uncoloured state. Heat can also help drive the reaction back to the uncoloured form, so in very hot conditions, there is always competition between light and heat to determine the given colour observed. In general, a colour change is still observed, albeit weaker than at room temperature. Similarly, in cold conditions in the presence of sunlight, an intense colour is observed as there is little or no competition from the back reaction. Such dyes incorporated within a sol-gel matrix can have several practical applications, such as optical switches (if the reversal is very fast) and optical storage for computer memory (if the reverse colour change is not possible at room temperature). Sol-gel Materials mixed with Photochromic dyes have also been investigated as fibre optic delay generators (Meer 1990), fibre optic shutters, and in Photomasking and Photoresist materials (Hawker 1993). Sol-gel based coatings may also be used for ophthalmic lenses such as scratch resistant coatings on sunglasses. The colouring changing process is described as the, ring opening/ring-closing process (Brown 1971) This is where the molecules lie flat in there closed form before UV radiation. In this state the substance is colourless. Once UV light is exposed to the substance, the molecules react by twisting, creating an open form. This open form causes the Photochromic dye to turn into a colour. Once the UV light is removed, the molecules twist back to their flat state, reversing back to the colourless substance. Depending on the intensity of the UV light and heat, the speed of which the reverse effect may vary. This process can be repeated many times; however the colour will become less and eventually dim. New Photochromic dyes are now being introduced to slow the fading effect and eventually stop it. Scientists can create different colours of Photochromic dyes by mixing Photochromic pigment powder. In their pure state, Photochromic dyes are powdered crystals that must be dissolved in the inks to which they are added. Some manufacturers microencapsulate the Photochromic dye in their own system, as with leucodye microcapsules. Microencapsulating Photochromic systems enables them to be used in inks that cannot dissolve them, such as water-based systems. Even on cloudy days, Photochromic dyes exhibit bright colour changes when taken outdoors. (Just as with lenses) The colour you see may differ slightly on very hot days or if a UV lamp, rather than sunlight, is used to excite the materials. 5. Organic Photochromism Fritzsche reported in 1867 the bleaching of an orange-coloured solution of tetracene in the daylight and the regeneration of the colour in the dark. Later, Meer found a change of colour of the potassium salt of dinitroethane in the solid state (yellow in the dark; red in the daylight). Another early example was published by Phipson, who noted that a painted gate post appeared black all day and white all night (due to a zinc pigment). Research and experiments into organic photochromism has enabled the photochromic process to be used on plastic and other materials. However, organic photochromism is controversial, as this goes beyond the domain of variable optical transmission and includes a number of reversible physical phenomena such as optical memories and switches, variable electrical current, ion transport through membranes, variable wet ability, etc. For this purpose, organic photochromic compounds are often incorporated in polymers and liquid crystalline materials. 6. The Chemical Process of Organic Photochromism Organic Photochromic materials consist of a polymer matrix of optical quality having a refractive state and at least one dye that imparts Photochromic properties to the matrix. A dye must be selected from a group consisting of spiropyrans and chromenes. This compound is then put under intense radiation to form Organic Photochromism. This then can be placed in specialist lenses and materials. 7. Organic Photochromism in Cosmetics In general cosmetic materials, Organic Photochromism is being used in cosmetic and related formulations. Colouration has been employed as a cosmetic device for many centuries (Farrer-Halls, 2007) Materials and methods for achieving predictable and safe cosmetic colouration are being continually explored and improved as evidenced by the large and expanding worldwide cosmetic business. Materials which change colour under the influence of light, i.e. photochromics, can be designed on the molecular level to interact with light to maintain, or even evolve a particular colouration. These materials can be designed to maintain a particular cosmetic look as the ambient lighting changes or as the user moves from place to place. It may be advantageous for the Photochromic response to be reversible. The influence of water can be anticipated and pH balance must be incorporated into the overall system design. It would be advantageous to design a class of materials for which ambient office light, or highly directed light such as in a tanning booth, or even laser light, could be utilised, each creating and imparting a particular predictable cosmetic look. There are, of course, many organic Photochromic materials. However, by necessity, to have a strong absorption feature in the visible part of the spectrum which could be the basis for an effective cosmetic colouration system, the molecular structure often contains a delocalised pi electron system (Farrer-Halls, 2007) Molecules having bonding features associated with such electronic structure, e.g. polycyclic aromatic hydrocarbons, coal tar products, azo dyes, quinoline, and like molecules with or without fused heterocycles, are often carcinogenic and so less desirable or unacceptable as candidates for use as cosmetics as Gill Farrer-Halls (2007, pg2) claims in her book, Naturals and Organics in Cosmetics Many types of organic molecules penetrate the skin barrier and so pose increased toxicity risk. This is a major problem because it would require more complicated testing and evaluation to establish the risk of such materials. Inorganic materials are well known which, because of their insolubility in water and their relatively large particle size, do not penetrate the stratum comeum to any major extent. For example, rouge, being iron oxide, and titanium-dioxide are two widely used oxides with well established safety history (Farrer-Halls, 2007) In fact, most metal oxides, with the possible exception of those used close to the eyes, are more likely ingested, and therefore dangerous if the particles are breathed. There is, therefore, a negligible risk if the oxides are immobilised in a cosmetic formulation. The objective of the design is to identify metal oxides, metal bronzes, and protein based Photochromic systems (materials) which combine novel cosmetic properties with sun blocking. (Farrer-Halls, 2007 pg5) Organic Photochromic systems have novel applications in cosmetics because the colouration they supply can be accented and softened and otherwise manipulated by the application of light, allowing greater control and range of effect than for a single colour application. Conventional colouration, i.e. rouge, can only be manipulated by mechanical means, i.e. rubbing and spreading. In addition to using these materials for their pleasing colouration effects, they can also be used as an actinometer/dosimeter that a person can use to gauge his/her exposure to bright sunlight or in other tanning/burning settings. The concept is based upon the use of the intrinsic Photochromic properties of certain solid transition metal oxides for cosmetic and sun blocking effects. The solid metal oxides suitable for use in this invention are those which undergo Photo induced and thermo enhanced loss of gas phase O2 to produce mixed valence oxides and include WO3, V2 O5, TiO2 and MoO3 (Farrer-Halls, 2007) A particular oxide can be operationally established for any possible choice of oxide by exposing a possible candidate oxide to blue-green or shorter wavelength light under vacuum and observing whether a colour change occurs. In some cases, the oxide is doped with an alkali metal ion or proton to enhance the colour change. As described above, tungsten and molybdenum oxide, and oxides of other metals, and bronzes derived from such oxides, constitute a broad class of materials having potential application as Organic Photochromic sun block/cosmetics. These materials are well known in the context of Photochromic optical data storage media and they offer an excellent match with the very properties needed for cosmetic applications. This relates to the adaptation of the class of tungsten and molybdenum oxide-photochromics to sun blocking/dosimetry, energy storage, and cosmetic colouration (Farrer-Halls, 2007) 8. Photochromic Textiles Photochromism in textiles seems to be a long and complicated process. However it is rather a simple method to produce dyes and inks that can be transformed into fibre to create textiles that react to UV light. Generally the colour-change inducing light has a wavelength in the visible or near visible range. Other factors which may affect the colour of these pigments have been cited by Glyn Phillips (1997 pg 4) include, temperature, moisture, electricity, and gases. Photochromic pigments have previously been applied to textiles by coating processes. Such coated textiles have aesthetic qualities associated with the Photochromic pigments. However, these textiles are not sufficiently colour-fast and their aesthetic qualities are easily destroyed by soiling. Mentioned previously, each time the colour changes due to the reaction of UV light, the colour intensity drops to eventually no apparent change will take place. It has now been discovered that Photochromic pigments can be blended into resinous fibers, yarns or non-woven textiles without substantial loss of Photochromic properties. The dye used can be introduced into this process from a master pigment batch obtained by mixing chromogenic pigments with a low melting polymer. (Phillips, 1997 pg. 5) In the process, the dye is blended with resin (the primary resin) and the mixture is processed into textiles by spinning and drawing or by the spin-bond process. The textiles manufactured by this process are advantageous over the prior method coated products in that the resultant Photochromic pigment-containing textiles are more durable (e.g., more colour-fast), more brightly pigmented, easily laundered after staining (e.g., by soil, solvents or oil) and readily woven directly into the desired fashion. Generally, conventional methods of blending polymers and dyes and of extruding synthetic fibers or non-woven textiles are used in this process. Blending can be done in a fusion type metric mixer, a volumetric type mixer or a weight type mixer. (Phillips, 1997 pg 7) The processes that may be used to manufacture the fibers or non-woven textiles include spinning and drawing processes, continuous spin-draw processes and spun-bond processes for the manufacture of non-woven textiles. However, these processes are modified in accordance with the concept/product such that the Photochromic dye is not subjected to a temperature in excess of about 250 ° C. Preferably, the Photochromic dye is introduced into the polymer mixing process in a master batch of polymer-encapsulated dye pellets. Such Photochromic dye pellets have been described, Generally, the amount of pigment in the masterbatch is from 1 to 10%, preferably from about 2 to 7%. (Phillips, 1997 pg 8) The use of dye pellets in place of directly adding dye facilitates uniform mixing and enhances the the overall process. For use in the production of synthetic fibers or non-woven textiles containing Photochromic pigments, the master batch is mixed with a primary resin, which may or may not be the same as the carrier resin in the master batch. The amount of masterbatch blended with the primary resin ranges from 1:2 to 1:100. The resins used as the primary resin are those with a melting point between about 105 ° C. and about 215 ° C. (Phillips 1997 pg 8) Useful resins include, polypropylene, polyethylene, polyolefins copolymers and terpolymers. Additional fillers and pigments, such as talc, silica, titanium dioxide, calcium carbonate, and conventional organic pigments, may be added either to the master batch or during the final fiber or non-woven textile manufacture process. 9. General Applications General applications of Photochromism can be divided into two categories: a) Those directly related to the change in absorption or emission spectra such as variable transmission optical materials, optical information storage, cosmetics, authentication systems, and flow field visualisation. b) Those related to other physical or chemical property changes such as refractive index, electric conductivity, phase transitions, solubility, viscosity, and surface wet ability. Photochromic can now be used in many areas of design. As photochromism has a wide range of solid states, from textiles to glass, (but only one function) most products which use this process are novel. Here are some examples; On garments to create novel products and promotional items like T-shirts On fabric/garment to print company logo / brand name to prevent duplication On garment which are used for party wear Thermometers and temperature indicators Security printing Food industry to indicate temperature of packaged food Photochromic substances can be found in inks, paints, papers and textiles. This property is a boon for scientists doing research on intelligent textiles and smart materials where they are making use of this property to store data on the surface of textile fabrics and polymer sheets. (Whereas the same property of some reactive dyes; is a bane for textile processors. The change in shade after dyeing creates unwanted problems in dyeing) An optical recording medium contains, on a base, one or more dyes and a polymer which forms liquid-crystalline phases. The information is written into the equally oriented liquid-crystalline polymer layer, for example by means of a laser. During this procedure, the polymer heats up locally to above a phase transition temperature. By cooling, the resulting change is frozen in the glass state. The information can be erased by applying an electric field and/or heating. The recording material permits high-contrast storage and possesses high sensitivity, good resolution and excellent stability. There are other chromatic properties called electrochromatism and thermochromatism of dyes that are affected by electric field and heat respectively. 10. Future Products The first Photochromic eye lens is being developed by scientists in Singapore, the Institute of Bioengineering and Nanotechnology (IBN), the worlds first bioengineering and nanotechnology research institute. This lens is another world first. The IBN has developed a Photochromic contact lens that will darken upon exposure to sunlight to protect the eyes against harmful ultraviolet radiation and glare. The lenses will conveniently adapt to changes in light and provide optimal indoor and outdoor vision. The IBN scientists also claim that this will help treat eye diseases by incorporating medication into the lens which can deliver medication effectively rather than eye drops. Another future product is Photochromic windows at home and workplaces. These windows will change colour when exposed to UV light from the sun, which will in return make home/workplace cooler and a more comfortable place to be in. Reversible Photochromic textiles have been around for 20 years, (mainly on novel garments) designers and scientists are trying to convert this technology into safety equipment and garments. The only drawback to this concept is that to make the product work during the night, when these safety garments are more needed. Photochromic relies on UV light to work effectively. Unless car head-lights radiate UV, this wont work, and car head-lights giving off UV light is a whole and completely different matter. As mentioned above in general applications, scientist can record and store data using Photochromic dyes. This data can be stored onto any material surface, but at the moment only being used on textiles. This technology has a huge amount of potential. Imagine the data on a personal USB device being stored onto a piece of fabric that the user can roll up into a pocket. The technology can be manipulated to give data back to the user through many objects. The user could watch/read the news on the users glasses; receive emails and correspondence and perhaps even text messages. The only drawback is responding to them. 11. Conclusion Photochromic technology has an immense amount of potential to create new products and in some cases a whole new lifestyle. Scientists can now manipulate Photochromic technology into most applications. Controlling the colour result of Reversible Photochromic is in itself a great achievement. Instead of a dull tone of grey, the colour can be anything from bright green to pink. Making Photochromic available in different materials, from glass to liquid, including textiles, makes this technology unique. Experimentation in novel-products, such as, T -Shirts that change colour when exposed to sun light, has enabled scientists to understand the chemical compounds and how to manipulate them to suit a concept. Now Photochromic technology is being used in more sophisticated ways, such as, the eye contact lens and storing data. This beak through in new technology can have fantastic results for future generations. It will affect the way people work and learn.

How the Rich Benefit from the Poor Essay -- Politics Political

How the Rich Benefit from the Poor this paper has problems with formatting The United States is the most developed capitalist economy in the world. The markets within the economy provide profit-motivated companies endless potential in the pursuance of pecuniary accumulation. Throughout the twentieth-century competitive companies have implemented modernized managerial procedures designed to raise profits by reducing unnecessary costs. These cost-saving procedures have had a substantial effect on society and particularly members of the working class. Managers and owners of these competitive and self-motivated companies have consistently worked throughout this century to exploit the most controllable component of the production process: the worker. The worker has been forced by the influence of powerful and affluent business owners to work in conditions hazardous to their well being in addition to preposterously menial compensation. It was the masterful manipulation of society and legislation through strategic objectives that the low-wage workers were coerced into this position of destitute. The strategies of the affluent fragment of society were conceived for the selfish purpose of monetary gain. The campaigns to augment the business position within the capitalist economy were designed to weaken organized labor, reduce corporate costs, gain legislative control and reduce international competition at the expense of the working class. The owners have gained and continue to gain considerable wealth from these strategies. To understand why the owners of the powerful companies operate in such a selfish manner, we must look at particular fundamentals of both capitalism and corporation strategy.

The Chicago Fire Of 1871 Essay -- essays research papers

The Chicago Fire of 1871 The summer of 1871 had been an unusually dry one in Chicago. Between July and October, only 5 inches of rain fell. In addition to twenty-seven fires in the first week of October, on Saturday night, October 7, a blaze broke out in a planning mill on the West Side and destroyed almost every building in a four block area before it was brought under control Sunday morning. They lost a hose and other fire-fighting equipment, including one of seventeen steam fire engines and a hose cart. Nearly half of Chicago's 185 firemen fought this fire and many were on duty all day, so they were already exhausted when the Great Chicago Fire of 1871 struck. Some people think that the fire was started by Mrs. O'leary's cow kicking over a lantern. Others have different theories, but one thing is for sure,on the Sunday evening of October 8, 1871 a blaze started in Mrs. O' leary's barn. Daniel sullivan sat on the wooden sidewalk when he saw a flame in Mrs. O'leary's barn. He managed to save a half grown calf. By now everyone in the neighborhood woke up, including the sleeping O'learys. The "America" hose cart was the first to reach the scene. They were soon joined by the "Little Giant" engine company.

Free Essay - Power of Guilt in Nathaniel Hawthornes The Scarlet Letter :: Scarlet Letter essays

Power of Guilt in The Scarlet Letter If a tree falls in the woods and no one is there to hear it, did it make a sound? This saying brings me to my thesis of "Guilt Without Confession leads to Great Consequences in The Scarlet Letter". If a character does something wrong but no one knows, that character can both gain and lose from what they have done. This happens multiple times in The Scaret Letter. Characters commit evil deeds, some are caught, some are not. For those that aren't caught, they have a decision to make. To turn themselves in or to live their lives as if it never happened. For those that choose to live on as if it never happened they are faced with a tough road ahead. They have to deal with the guilt of what they've done. All the while, they must watch to see if anyone is on to them or suspects them of the crime they have commited. However they are rewarded. They get to live on as a regular member of society rather than be imprisoned or even worse, put to death. These are examples of characters who have commited crimes without confessing. Arthur Dimmesdale is a minister, a father, a sinner and a man who feels incredible guilt. He commits adultery with Hester before the book begins. As the book begins it is revealed he is the true father of Hester's child Pearl. Dimmesdale, afraid of losing his status and being humiliated , does not confess his crime. For this this he is rewarded and greatly punished. He is rewarded by keeping his status in the community. He continues to preach to his flock, for which he gains great acclaim. He is able to see Hester and Pearl whenever he wants. He is also free to leave anytime he wants. He has his freedom and his reputation. However, he also has something he doesn't want, his conscience. How unfortunate it is a person can get away from being caught for a crime. A crime that is punishable by death. Yet, he can't enjoy it. Most people would leave town, sorry for that they've done, but ecstatic they got away to start a new life. Not Dimmesdale, not Reverend Arthur Dimmesdale. He beats him self up over it. Usually thats an analogy, but not this time.

Redbull Marketing Communications Essay

Redbull Marketing Communications Digital Campaigns Clarisonic launched a campaign in October 2010, Breast Cancer Awareness Month, in which the company promised to donate 1$ for every new like they received on their facebook fan page. Clarisonic used Facebook advertising, email blasts, twitter, youtube and even their own blog â€Å"Sonic Chatter† to spread the word about their new ‘like’ campaign. Clarisonic objectives included adding a thriving social media section to Clarisonic’s traditional cause marketing for nonprofit. Furthermore, Clarisonic wanted to increase awareness of their brand and products, as well as increase awareness of their Facebook page. Another objective, which was the most direct objective, was to raise money for â€Å"Look Good†¦Feel Better. † Attaching their name to this cause also allowed them to increase sales for their specialized products like Pink Clarisonic, which also benefits the â€Å"Look Good†¦Feel Better† charity. Clarisonic also aimed at marketing beyond their typical target audience of women in their late 20s-50s. Some limitations that were faced was that it was only a two month project and although it attracted a lot of views, interactions, and new Facebook fans, they would have to constantly engage the new fans that were outside their target market, who may not be interested in their actual products being sold. Partnering with â€Å"Look Good†¦Feel Better† was a perfect fit for this campaign because both companies focused on transmitting a message of empowerment. Redbull: On October 14, 2012 the world witnessed a breathtaking experiment; Red Bull Stratos. It took viewers to the edge of space and it was all organized by a private organization, Red Bull. The Red Bull Stratos mission was a record breaking event, one which saw Felix Baumgartner free fall from more than 23 miles above the earth, breaking a free falling world record while becoming the biggest digital live event on record. It reignited a yearning for the extreme, and created a distinct association with what was Extreme and Redbull. The objectives of Redbull marketers was to reach a lot of people, to excite them, give them something to talk about and look forward to and then to directly relate this â€Å"coolness† to drinking their product. They wanted to break world records, not only in the actual freefalling aspect but the hype around the event. This hype could then be translated hopefully in an increase of brand awareness and in turn, an in crease in sales for Redbull. Clarisonic: Clarisonic targeted current consumers of their product by advertising about the campaign on their blog, which users of their product read, as well as non users by making the campaign goal not just relevant for women or those that are in their 20s, 30s. The campaign therefore targeted a much broader audience, those that frequent charity events and support a good cause, not simply women in the beauty care sector. By making their campaign about much more than a physical beauty care product but something that benefits the greater cause, they were able to target men and women of all ages who support cancer organizations and link this support of a good cause with their brand. Redbull: The audience that was targeted in the Redbull campaign was extreme sport enthusiasts as well as the entire world that would also be excited to watch a world record breaking event. The target audience was broad and expanded past extreme sport enthusiasts which most of Redbulls marketing targets. Clarisonic: Clarisonic campaign was extremely ethical as it raises awareness of a certain cancer fund, donates money to the fund, and through these actions is able to also increase awareness of their brand and better their image. Had most of this money not gone to a cancer organization, and just gone to supporting the brand, perhaps it would be less ethical. Redbull: One could argue that the risk involved in this campaign was too much to be considered an ethical campaign for Redbull. Yes, it attracted a lot of new consumers and created record-breaking brand awareness but it was at the risk of being at the cost of a human life, which is unethical. Clarisonic: They were extremely successful in one of their main objectives, which was to raise money for the Look Good†¦Feel Better cancer organization seeing as they raised $1 million dollars and increased awareness of this great organization. â€Å"Likes† as well as interaction on their Facebook page continued to grow even after the two month campaign and n 2010 alone, their selling of their â€Å"Hope† Mia skincare brush more than doubled compared the previous year. Clearly no one can know for sure if it was directly because of the â€Å"like† campaign but it is safe to say that the increased awareness did contribute to an increase in sales of Clarisonic products. The like campaigne increased Clarisonics fan page by 80 percent. Redbull: Without a doubt Redbull achieved its objectives of showi ng the world something that has never done before and reemphasizing their brand motto â€Å" Redbull gives you wings. This event had a huge brand impact on Redbull. Not only did this campaign beat records and was unprecedented scientifically, it was also beating records in a brand marketing perspective. 1,000,000 distinct user accounts were involved in the conversation regarding RedBull Stratos with a suggested audience of this content being up to 90,000,000. 2,000,000 new accounts were subscribed for Red Bull updates within a span of 15 days surrounding the event, these updates included all brand presences in the digital world. These represent engaged consumers that could possibly one day turn into paying consumers of RedBull. Most campaigns, much like Clarisonic are dominated mostly by likes or â€Å"neutral commentary† yet Red Bull Stratos had unmatched positivity and meaningful interaction from people around the world; more specifically 820,000 pieces of extremely positive content was created in regards to Redbull Stratos. 50,000 distinct links were shared about Red Bull Stratos. More than 8 million concurrent live streams of the Redbull Stratus jump on YouTube was had which was the largest in Youtube’s history. This kind of huge reach transcends RedBull Stratos and reaches Red Bull branding in almost ever single comment or interaction, which till this campaign and to this extent was unheard of. According to Vocus, sales of Redbull increased by 55% in the first few months following the campaign so already here we can see that not only did this boost brand awareness and image, it had a direct impact on offline consumer behavior. Clarisonic was always tied to cancer awareness funds in the past, their product line, Pink Clarisonic previously donated some proceeds to the Feel good, look better fund so this new â€Å"like† campaign wasn’t a trigger of some outside market force, it was more an expansion of what was already underway internally in their brand image and concept of empowerment. Furthermore Breast Cancer awareness month was also somewhat of a trigger to tie their brand with this month awareness. Clarisonic competitors are low priced beauty products such as Olay Pro X which did not stray from their traditional marketing ways despite the success of Clarisonics like campaign. Personally, I would make this marketing communication campaign longer than two months, allowing the attention that Clarisonic was receiving to be exploited further. I would also allow fans that mentioned Clarisonic on twitter to receive small samples of new products Clarisonic has, thereby engaging target consumers with the actual product at hand. Timing of this campaign was definetly in Clarisonics Favor. Breast cancer awareness month is a time where many want to donate themselves to the cause and this like campaign allowed them to do so effortlessly and without their own money, simply their participation in a brand they may not have been aware of. Connecting themselves with Breast Cancer Awareness month also lends greatly to a better image for Clarisonic. Twitter did not participate greatly in this campaign other than to advertise for the campaign on facebook. Salespeople were not utilized in this champagne either which also could have further helped promote their products as well as their like digital campaign. Redbull: Redbull was always tagged with an idea of extreme sports, they sponsored athletes, had their own extreme sport web episodes, and could be found at most sporting events. Therefore, the fact that this was the company that decided to do something so extreme and create so much digital hype around this event was definetly no surprise considering past records of RedBull. It was not triggered by stunts pulled by their competitors. The Redbull Stratos was able to reach millions more than their usual marketing antics. I would not recommend a thing to the Redbull Stratos campaign, I think everything they did digitally to boost this campaign was genius. The message was simple; Redbull gives you wings and with a record-breaking free fall, they proved this. Millions will always associate the feeling of â€Å"cool† and â€Å"extreme† with drinking RedBull, and that in my opinion, can only be done by indirect selling of their drinks. No commercial or online campaign could create such brand association by simply telling consumers how cool their drink is.

Theories of Psychological Development

Developmental psychology is the scientific study of adult male changes across their deportment span. It is important to study psychological phylogeny to realize how and why people go through sealed changes throughout their spirit. at that place be many antithetical aras of psychological instruction. Two main aras are perceptual exploitation and emotional raisement. They some(prenominal) hand over theories that can be related, but in the commencement exercise place you can understand the relations, you must first understand the 2 theories.The possible action of perceptual development was created by an American Psychologist named Eleanor Gibson. It states that perceptual development is the process of an infant exploring its endlessly changing environment and deciding what to do and how to act with the newly found information. Affordance geographic expedition is also a key feature article of perceptual development. Gibson believed that affordances are visual cl ues to the functions of an object. An use could be a someone lift a foot race.The child could examine how the lam unavoidably to direct a stable base and lean against a certain object to keep from falling down. When affordances are found, speciality starts to occur. Gibsons definition of differentiation is basically the ability to discriminate different environments. If you look back at the die hard example, the infant uses affordances to see the ladder needs support to stay upright. Then the infant uses differentiation to see a person is more safe standing in the middle step of a ladder than the top step.As the infant experiences more and ages, it becomes better at differentiation. Emotional development is based around a theory called the fastener theory which was created by a British psychiatrist named John Bowlby. The fond regard theory is the act of developing an affectional bond with someone who is considered a angel dust (Bowlbys definition was a steadfast p sychological connectedness between human beings). It is crucial for a childs behavior in the present and prospective(a) to lay down an attachment relationship with a primary care provider.Bowlby stated that for an attachment to be difficult, 4 characteristics need to be present law of proximity maintenance (the desire to be in the presence of the primary care provider), safe haven (returning to the phencyclidine hydrochloride when feeling unsafe), secure base (considering the health professional as a source of security) and withdrawal distress (feeling anxious when the caregiver is non present for an extended period of time). Bowlby believed that strong attachment relationships develop after the caregiver and child become closer.Mary Ainsworth (a preliminary student of Bowlby) was an American Psychologist who believed that there are three types of attachments secure, avoidant and resistant. A secure attachment is formed when the caregiver is used as a safe home and the i nfant feels less safe when the caregiver is negligent than when they are present. An avoidant attachment is basically the diametral of a secure attachment. It is when the caregiver is considered a stranger by the child and they chasten to avoid the caregiver as much as possible to feel safer. A resistant attachment is a part more complex than the other types of attachments.It occurs when the caregiver is unresponsive to the childs needs making them feel unsure what they motivation or need which makes them feel inefficient to count on their caregiver. There are some relationships between the theory of perceptual development and the attachment theory. According to the two theories, both require a amenable caregiver for a child to have a proper and healthy development to be able to experience affordances and to have the right caregiver provide the environment to do it in. Also, your caregiver could be amenable for a child not tuition certain affordances which could affect them in their future life.Another way to look at it is if a caregiver never provided the aspect for the child to experience affordances related to a job that requires experience in, say, the construction industry, accordingly they will struggle psychologically in the future to earn that job or any job that they may want. perceptual and emotional development are both very important to a childs psychological development. It is important to understand the two main theories behind them to look out what is required for a child to develop healthy and normally to live the life that they want to live.
