Include strategies Essay Plan, implement and evaluate at least three activities for children in the foundation stage. You should ensure that across the three plans there are learning goals from each of the 6 areas of learning. Your plans should include strategies for differentiation.  Claire Field  Preston College  Introduction  The purpose of this work is to review the nature and content of the foundation stage curriculum and to consider the theoretical underpinning and underlying principles that have assisted in the formation of this early years practice. Through the planning and implementation of three activities, spanning the full spectrum of the foundation stage curriculum, the writer aims to identify and meet the needs of foundation stage children. This work will then evaluate the provisions for these children and investigate further the ways in which differentiation strategies can be implemented to ensure all children, regardless of their abilities, or stage of development, may receive the curriculum, delivered in a style appropriate to them and their own personal requirements. In 1988 the Conservative government, under the leadership of Margaret Thatcher, legislated that a National Curriculum be in force for pupils between the ages of 5 and 16, because she believed that  a good educational system was essential for the future  success of the nation (Ridley, 1992, p92)  Although a curriculum was in place for ages 5 to 16, there was a distinct lack of standardised learning for the early years. Margaret Hodge joined the Department for Education in 1998 and was responsible for reforming pre-school education policy (www.news.bbc.co.uk 12/10/2006). She was actively involved in the implementation of the Foundation Stage Curriculum in September 2000 and the publishing of the guidance to accompany this. The abilities of children are multifaceted and the foundation stage curriculum gives practitioners a much less rigid approach than the National Curriculum, by following the childrens progress using stepping stones. As the foundation stage curriculum is a government legislated policy, this means that all children should follow it. As it is flexible in the way in which it is implemented, it means that different types of settings can fashion the teaching methods to follow it in their own way. This means that whether a child attends a pre-school, an LEA nursery, a work-based nursery, or indeed a childminder, they are provided with the same curriculum. This is governed by Ofsted who maintain this proviso through their regular inspections. Good planning is essential in ensuring that all the practitioners involved can build a picture of the childrens development programme. Not only does it provide them with a premeditated programme of learning, but it also gives an opportunity for discussion to take place, where they can think about how they can progress children through the various stages of learning. For the practitioner to ensure all areas of the curriculum are covered, the planning must,  entail attention to overall (long-term) planning, medium  and short-term planningfor every aspect of every  lesson (Cohen et al, 2004, p125) Long term planning ensures that all the areas and aspects of learning within the curriculum are covered throughout the whole year and provides a template for the medium term planning. Correct use of the Curriculum Guidance for the Foundation Stage, together with the knowledge of the practitioners relating to the individual children, means that the children experience new and exciting ways to learn through play. The long term plans of the settings must be flexible. They should incorporate the schools ethos and provide for an enriched curriculum with scope for differentiation to allow inclusion. Medium term planning then identifies the specific topics of work to be covered over the term, or half term. From these the practitioner then sets out the weekly activity plans, to guarantee full coverage of the learning outcomes within the set topics. It is vital that the plans cover the whole of the six areas of learning and that the practitioner assesses the progress of the children, in order to make certain that they are all progressing to the best of their capabilities. Recording achievements as stepping stones enables early years practitioners to carry out assessments whilst the children are involved in activities, thus preventing the child having any knowledge that an appraisal of their skills and understandings is being undertaken. Planning and evaluating the success criteria of an activity allows the practitioner to be certain that every area of the curriculum is covered. Piaget introduced three principles of cognitive development and these apply to all of the subjects studied in this report. His first principle is assimilation. He says that children do not absorb all the information they encounter. They actively engage in the assimilation process and learn what is relevant to them at their stage of development. The schema stage is next. During this phase the children relate what they know already to their current situation. The third phase is where the child wishes to seek stability cognitively. He utilises the knowledge gained and applies it to make a general logical picture (Oakley, 2004). From this it is clear to see how the children gain the learning and knowledge applicable to them by interpreting activities in their own way.

Globalization in Sub-Saharan Africa Essay Example for Free

Globalization in Sub-Saharan Africa Essay ABSTRACT It is factual that globalization began before the industrial revolution was existent in the colonial period and continues to be a major influence on how governments worldwide operate. When analyzing the effects of globalization, a common controversial debate is whether globalization has maimed the society or has brought significant benefit. The African society is used severally by anti-globalists to defend their views. This paper explores the negative dynamics of globalization in Sub-saharan Africa e.g. undermining of state sovereignty and hastening of environmental degradation of the continent. However, it does not suggest that globalization is entirely bad nor does it say that globalization is the only cause of Africa’s problems. It proposes some measures that can be considered when globalizing the African market so that this negative effects can be minimized. INTRODUCTION The nations of the world have synchronized their trading goods and services, financial markets, Ideologies, innovations and cultures through globalization. The free flow market policy adopted by many countries has led to significantly positive outcomes in the broader African region for example, creating new job ventures and advancements in technology. However, globalization has also cast a dark shadow on some sectors of the African economy , an issue that this paper will put into perspective with a particular case study on the Democratic Republic of Congo. Some proposed consequences of globalization addressed here include increased conflicts in the area, erosion of state sovereignty, imbalance in the ecosystem and income inequality. Sub-Saharan Africa is a term used to refer to all of Africa except the Northern region. Most of their economies are agricultural based and are not as stable as those in the Western world. The average income in sub-Saharan Africa is below the poverty line level. Nevertheless, this region enjoys a large comparative advantage on raw resources in the extractive industries for example minerals and oil. The demand for these minerals can perhaps explain why immediately before the great recession in 2008,there was the 27% increase in FDI; the highest ever seen(Jaja:3).Foreign companies can obtain these minerals at a very low cost in some African countries and reap huge marginal benefits. Some of the avenues they use to get them are questionable as is the case with the Democratic Republic of Congo. The Democratic Republic of Congo (formerly Congo Zaire) is a central African nation that borders the Atlantic Ocean to the west. Its neighbouring countries include Central African Republic Southern Sudan, Rwanda, Burundi, Angola and Tanzania (the two are separated by Lake Tanganyika).It is the second largest nation by area with over 65 million people. It was a Belgian colony and gained independence in June 1960. DRCongo has the most variety in biodiversity in Africa and enviable amounts of rare natural resources such as diamond, copper, gold, cobalt, timber and coltan. With its resources one would expect that such a country would be awash with prime economic developments, projects to exploit all agricultural potential and high standards of living. On the contrary, most of the civilians in DRC live in poverty and have not benefited from the rich well of resources they have. They are victims of years of civil war, propelled by power- hungry, conniving national leaders and part of the international community. A sneak peak into the colonial history of DRCongo reveals that the exploitation of the minerals for self-intrests is not a recent phenomena. POLITICAL BACKGROUND OF THE DRC In the late 1800s, King Leopold of Belgium acquired full rights of ownership of the Congo territory at the Conference of Berlin. He governed it like private property and the area experienced some developments. However, this came at the expense of the local people because they were treated as slaves and could not reap any fruits from their labour. Intense pressure from the international community on the Belgian parliament led to the reclaiming of the Congo region from the king’s hands. It was renamed The Belgian Congo state from 1908. There was significant economic growth at the time but the indigenous people were on the losing end again, exploited and enslaved. The fight for independence was won on June 1960 with Patrice Lumumba as Prime Minister and Joseph Kasavubu as president. Lumumba would later be fired and Joseph Mobutu, chief of staff of the new army, aimed to ‘restore’ the relationship between the two leaders with the help of the USA and Belgium governments. In January 1961, Katanga forces and Belgian troops executed Patrice. The Katanga succession ended in 1963 with the help of UN forces. There were several governments afterwards; the most notable one being that of Mobutu Sese Seko. His ‘career’ as president began in 1971. He was largely dictatorial; for example he revoked the powers of the legislature, fired the prime minister and conducted an election where he was the only candidate. Funds were mismanaged, state cooperations collapsed and the country was in debt. He renamed the country several times but officially used Congo-Zaire. Note that he had several billions of US dollars in a Swiss Bank account and still had favour with the USA government. It is believed that he even had a world bank official as a personal assistant. This in turn gave him â€Å"confidential information about granting aid to Zaire†. (Reno 1998:152) In 1994, the DRC was a refuge for the many Rwandese Hutus fleeing the Rwandan genocide. Refugee camps a few kilometers from the border with Rwanda were planning zones for attacks into Rwanda. Mobutu cheered them on. However in 1996, Rwandan led forces backed by Uganda and the The Alliance of Democratic Forces for the Liberation of Congo-Zaire, led by Laurent Kabila, advanced into Kinshasa to close down Hutu camps in Eastern DRC.As a result, Mobutu’s government was overthrown when he was away and Laurent Desire Kabila was declared president. Kabila’s leadership was no different from his predecessor’s. Conflict between his government and rebel groups ensued in August 1998 because Kabila saw the Rwandese rebels as threat to his government. The Ugandan group, led by Congolese warlord John Pierre Bemba, formed the Movement for the Liberation of Congo, joined the Rwandese and together they terrorized the citizens and the government .Kabila requested for military assistance from the international community but they hesitantly supported him since they did not know him enough to trust him. In 1999, the rebels and the government signed a peace accord and six other countries were witnesses. A new constitution was promulgated in May 2005 and in 2006 the first free and fair elections were held. Tension increased just before elections and the government, backed by the UN, disarmed all non- governmental factions to keep the nation stable. The trail of this civil war commonly equated to Africa’s first world war has left a trail of death, despair and pain amongst the people with over 5 million dead, several displaced, and thousands of women and children raped. It is interesting to question the ability of the rebel groups to oust governments sequentially. Could someone be funding them? Are there some hidden interests? The minerals in the DRC, and coltan in particular, are treasured gems in the technological era. When raw, coltan, which is composed of columbium and tantalum, looks like black mud or sand. It is used to produce capacitors. Capacitors are used to conduct electrical charge in high tech equipment for example cellular phones, computers and some jet engines. The DRC has the world’s largest reserves of the mineral. Four fifths of the world’s supply of coltan is in Africa and DRC has eighty percent of it. In the late 1900s,the sales of tantalum increased by three hundred percent. This time period coincided with the times of civil war in the DRC.As Dena Montague states in her article, â€Å"Stolen Goods: Coltan and Conflict in the Democratic Republic of Congo†, international cooperations such as Banro-resources cooperation, Finconcorde and Raremet imported DRC coltan via Rwanda for use in Asia, Europe and US A. In response to UN accusations of involvement in illegal trading H.C Stark, one of the largest producers of capacitors commented that they only purchase raw materials from established companies. However, established companies were indeed involved in illegally obtaining goods from DRC. Investors restructured deals in support of Desire Kabila instead of Mobutu in 1996.This was a violation of the constitution which stated â€Å"The soil and subsoil belong to the state-prospecting, exploration and exploitation requires permits from Ministry of Mines and Energy.† Local militia backed by Ugandan and Rwandese forces got supplies in form of food, money and military equipment in exchange for smuggled goods. The militia men took stronghold of areas with huge deposits of gold and coltan e.g. Bukavu, Lubumbashi and Mayi. Gold was exported through Uganda and into United Arab Emirates. It was difficult to trace from there. It is worth noting that between 1995 and 2006,gold was one of Uganda’s main exports. Additionally, Uganda had GDP growth rate of 6% per annum in 1999 yet the average GDP in Sub-Saharan Africa was about 2.5%in the same time. These trade revenues undermined the power of the central Congolese government because the Ugandan economy gained more from D.R. Congo’s resources more than the DRC’s economy did. The fact that the international community was in one way or another involved in increasing conflict in the DRC is undeniable. If the corporate investors were genuinely trading with DRC to improve the state of the country, they would have questioned the legitimacy of the DRC based enterprises and suppliers. Another simultaneous consequence of the years of instability was an imbalance in the ecosystem. Wildlife products such as elephant tusks and animal skin were and are still very marketable globally. They were sold or bartered in exchange of food, ammunition and other goods. With a nation in strife, this meant that there were neither environmental regulations nor expensive wildlife products. In the 1990s, there were increased rates of elephant poaching and habitat encroachment in the forest areas of Kahuzi Beiga National Park. Statistics by the UN reveal that in the area of Garamba Park, north eastern DRC, 4000 out of 12000 elephants were killed between 1995 and 1999.[61]The area was controlled by Ugandan troops and Sudanese rebels. This created a human-animal conflict. The militia fed on wild meat when on their missions. Wild meat was also the only easily available food source for the displaced persons. Rebel leaders disarmed the guards in national parks, thus they were unable to patrol the forested areas. Local conservationists also raised the alarm on the decreasing numbers of the bonobo monkeys; famed for language learning abilities when in captivity and complex social behavi or in the wild(Gretchen Vogel).Another result of the clash between man and animal as suggested in the article â€Å"Effects of War and Civil Strife on Wildlife and Wildlife Habitats†, was the spread of human monkey pox and bubonic plague. The people were exposed to more diseases other than water- borne and tropical diseases. With lack of adequate healthcare and restricted movements, the people’s lives were at risk too. The flora and soil were not spared either. The people burned the vegetation and cut trees to get timber and to create room for living and farming. Due to the uncertainty they were in, it is unlikely that their methods of farming were conservative e.g. overharvesting and thus leading to soil erosion. Timber, which is a fundamental raw material for the building industry, was cheaply available to local and international traders thus they found the political situation in the DRCongo very favourable to their activities. Globalization of trade and financial commodities in the world has a general pattern where most of the trade and investments are dominated by a few nations. They make policies that work to their advantage, a fact clearly outlined by Joseph E. Stilitzp in his article â€Å"Globalism Dis contents†. Agriculture, which is the backbone of many African countries, is sometimes left out in some of the import tariff reliefs given internationally on account of globalization. Some regional agreements also exercise some form of discriminatory trade towards agricultural products. Additionally, globalization has led to liquidity of funds due to free financial markets. This means that capital investments can quickly be converted to cash. African states are become vulnerable to liquidity perhaps because of several sectors of the economy that need quick monetary solutions and overreliance on foreign loans as Stiglitzp highlights. One probable outcome from this phenomena in the period of conflict in the D.R.C would be that the rich political leaders in the country became richer and richer whereas the common people sunk deeper into poverty. It is likely that the agricultural sector was neglected(and this is where the people economy was/is based)and the mining industry prioritized. Middlemen from some countries traded weapons and money, with the rebel groups and some political elite, for coltan and other minerals. It is also likely that some foreign companies were given full ownership rights of some mines after giving the leaders of the time were given some money. The Congolese will indeed find it hard to trust their leaders again. The harsh reality right now is that so many families are focused on the primary needs of fending for their families so the idea of demanding for their rights is would sound unpractical. The fragility of this state can be traced to the days of state formation and the nature of subsequent governments. If the leaders who came into power prioritized the formation of a strong army and building of the nation, then we would perhaps tell a different story. This region and several others in Sub-saharan Africa have faced a humanitarian,environmental and political turmoil for too long. To avoid a repeat of the civil war situation and its consequent effects, specific codes of conduct that promote economic and political stability should be considered in the globalization aspect. Foreign investments into Africa require strict policies and an end of the bargain that considers the welfare of the people e. g a company that wants to invest must contribute directly or indirectly towards building a hospital, school or social hall. This will be effective in ensuring that the transition between a globalized market and the previous one involves the whole society in all dimensions of life. This can only happen with government system that is dedicated to building a brighter future for these great nations. The effective building of DRCongo’s economy will involve Congo’s immediate neighbors, the whole of Africa and the world. Conservationists should develop programs in war torn areas so that resource conflicts do not arise in the future. Global gatherings that address environmental issues should also prioritize the critical environmental crisis the Democratic Republic of Congo and in other areas affected by similar or even worse conditions.

Applications of Hard X-ray Photoelectron Spectroscopy

Applications of Hard X-ray Photoelectron Spectroscopy Applications of Hard X-ray Photoelectron Spectroscopy to bulk materials Jingru Chi ABSTRACT X-ray Photoelectron Spectroscopy is a powerful, relevant and non-destructive method for studying atoms, molecules and surfaces [1]. However, investigations are limited to atoms, molecules and surfaces since low energy electrons limit the depth resolution, resulting in three-dimensional bulk state cannot be detected. Hard X-ray Photoelectron Spectroscopy (HAXPES) with high kinetic energy photoelectrons uses excitation by X-ray of 2-15keV and a high energy analyzer which make it possible to measure bulk and determine bulk electronic structure properties of materials [2]. The recoil effects of photoelectrons in valence band states and core levels are the principal studies of HAXPES. In this paper, HAXPES uses undulator synchrotron X-rays at SPring-8. The results of high energy photoelectron spectroscopy of the valence bands and sensitivity of bulk have shown that the measured valence band spectra are indispensable in studying the bulk electronic structure. Introduction The Nobel Prize in 1981 was awarded to Kai Siegbahn for developing the method of Electron Spectroscopy for Chemical Analysis (ESCA), now which is presented as X-ray Photoelectron Spectroscopy (XPS). Since then, XPS becomes one of the most useful and non-destructive techniques for analyzing the electronic structure of atoms, molecules and surfaces. In early studies, XPS uses Mo KÃŽ ± (= 17.479keV), Cr KÃŽ ± (= 5.417keV) or Cu KÃŽ ± (= 8.047 keV) hard X-ray sources. Gradually it out of date with the discovery that lower energy soft X-rays such as the Mg KÃŽ ± (= 1253.6eV) and Al KÃŽ ± (= 1486.7eV) sources has the higher energy resolution [3]. Reducing incident energy improved the surface sensitivity of XPS. However, soft X-rays source limits the depth resolution to 5nm for Angle-Resolved X-ray Photoelectron Spectroscopy (ARXPS) and 10nm for inelastic loss analysis [4], so it cannot detect the deeply buried layers without destructive ways like ion sputtering and etching which are time-c onsuming and hard to control. In the last few years, the developments of new bright synchrotron photon sources, the availability of monochromators with a resolving power about 105, and electron analyzers which can analyze the 10 keV electrons with meV resolution have created the new possibilities for Hard X-ray Photoelectron Spectroscopy (HAXPES) [5], which made it possible to analyze the bulk structure without using destructive methods. HAXPES has not been well-developed until the appearance of the third generation synchrotrons, which can generate high-brilliance, high-flux X-rays that enables one to perform experiments with the HAXPES in very low photoionization cross-section [1]. As well the developments of electron analyzer with the high kinetic energy range also contributed to improve HAXPES measurements [6]. The superiority of HAXPES is the considerable probing depth owing to the increased electron mean free path [7], made it possible to detect the electronic structure of bulk materials. With the excitation energy of 8 keV, the escape energy can be greater than 90 Ã… [1]. With high kinetic energies of electrons, the coral level and the valence band can be detected in the bulk materials. According to these advantages, HAXPES is one of the best ways to perform sensitive photoemission spectroscopy on correlated systems such as thin films, multilayer systems and devices [1]. Several investigations on bulk materi als have been reported. One is the measurement of the valence band of Co2Mn1−xFexSi (x = 0, 0.5, 1) be excited by photons which have energy about 8 keV [8, 9]. This experiment was the proof that the XPS with hard X-rays has better sensitivity on bulk electronic structure than the conventional XPS with soft X-rays. Fundamentals of HAXPES Model of photoionization using hard X-rays When use the conventional theoretical model to describe the photoemission, including the differential cross-section of photoionization for photon energies from 2 keV to 15 keV, the model based on the power series expansion of the electron-photon interaction operator cannot perfectly explain photoemission though just using a limited number of the terms of the expansion [2]. However, a more complex expansion of the electron-photon interaction operator developed by Fujikawa [11, 12] contained all the electric dipole operators and other multipole terms can explain it well. These models indicate that contributions from electric quadrupole and magnetic dipole transitions cannot be ignored anymore when photoelectrons are excited by high energy X-rays and beyond the electric dipole transitions [2]. Systems Fig. 1. HEARP Lab system [10] There are just so many kinds of HAXPES, here just introduce the HEARP Lab system. In this system, it needs the monochromatic X-ray source with 5–6 keV photon energies and the high energy electron analyzer with angular resolution capability for the measurements of takeoff angle dependence and X-ray photoelectron diffraction [10]. To meet these requirements, HEARP uses the Cr KÃŽ ± X-ray source, a wide acceptance objective lens, and a high energy version of VG SCIENTA R4000 analyzer [10], as it showed in Fig. 1. A Cr KÃŽ ± X-ray source is shown in Fig. 2(a). The main body contains the water cooling system and Cr target. At the first, the monochromatic Cr KÃŽ ± X-rays are emitted by a focused electron beam with the maximum acceleration energy of 20keV, then X-rays go through the bent crystal monochromator with a 300mm Rowland circle and focus onto a sample surface [10], as schematically shown in Fig. 2(b). The X-ray spot size ranges from 1.5ÃŽ ¼m to 200ÃŽ ¼m by raster scanning of the electron beam [10]. (b) (a) Fig. 2. X-ray source [10]. (a) Photograph of UHV compatible flange mounted Cr KÃŽ ± X-ray source [10]. (b) Schematic diagram of X-ray source. The electron beam is focused on a water cooled Cr target [10] and it excite Cr KÃŽ ± X-rays. Then it monochromatized by an elliptically bent Ge crystal with 422 reflection [10] and direct irradiated to the sample surface. The objective lens, as it shown in Fig. 3(a), is set in front of the analyzer. The angle acceptance of the lens is about  ±7 °, when it is combined with the VG SCIENTA R4000 10 KV hemispherical analyzer, the angle acceptance can achieve to  ±35 ° [10]. The magnification factor is 5, as well the magnification factor of analyzer input lens is 5, so the total magnification factor is 25 [10], and the working distance is 11mm from the aperture [10]. (a) Fig. 3 Performance The performance of HEARP system is evaluated by measuring Au 3d5/2 photoelectrons emitted from an Au strip. The total energy resolution is 0.53 eV [13]. The result of the experiment showed the acceptance angle is  ±35 ° and a resolution less than 0.5 ° [10]. When it is provided with the objective lens, the acquisition time for the Au 3d spectrum excited by the same Cr KÃŽ ± source is 16 min, which is seven times better than without the objective lens [10]. Table 1 shows the differences in HEARP Lab system and HXPES at BL47XU beamline system. Table 1 Comparison of HEARP Lab system with HXPES at BL47XU beamline system. They all have the same analyzer with the same pass energy of 200 eV. In the Lab system, it uses entrance slit of curved 0.8mm, beamline system uses curved 0.8mm. The X-ray excitation power is 45W (15 kW, 3.0 mA) [10]. Applications References [1] Siham Ouardi, Gerhard H.

The Wealth of Nations Essay examples -- Economics Economy Politics Ess

The Wealth of Nations Adam Smith’s famous attempt to explain the nature and causes of the wealth of nations rests on several crucial assumptions about human nature which in turn rely on false universalism and questionable dichotomies. To begin with, Smith makes roughly three claims about human nature. Primarily, Smith assumes that self-interest is inherent in all human beings. As opposed to animals which rely on benevolence, in opposition to natural pity (Rousseau p. 53), the human â€Å"will be more likely to prevail if he can interest [others’] self-love in his favour, and show them that it is for their own advantage to do for him what he requires of them† (Smith, p. 18). Smith later relies on this â€Å"self-love† to ground his arguments on the steady base of human nature. More subtly, the â€Å"faculties of reason and speech† play a crucial role in Smith’s treatment of human behavior. Although he never openly lists these â€Å"faculties† as essential to human nature, his argument relies on this assumption. The step from having some goods and needing others to trading with those who have the needed goods and want the overabundant ones cannot be warranted without a presumption of a rational actor. Similarly, every development towards improved efficiency, if these are anything more guided than random evolutionary steps, require such an actor to instigate it. In the case of the arrowmaker, Smith must assume some force driving the arrow maker to save time and maximize profits. Of course, the concepts of barter, trade, and the rest require speech, or some kind of communication. Finally, Smith instills â€Å"a certain propensity in human nature; the propensity to truck, barter, and exchange one thing for another.† (Smith p. 17). This, he sugg... ...to the commonness of rationality. Far from all cultures were capitalistic, nor is it possible to prove any would have become capitalistic in the future. Thus Smith’s description of human nature is applicable primarily to Western European coastal trading humans, rather than to the supposed universal and original human specimen.

Women as Sexual Objects in Metropolis :: Movie Film Essays

Women as Sexual Objects in Metropolis In the film Metropolis, I feel women are basically represented as a sexual object. Also in my opinion certain male figures were the dominant images throughout the whole movie. Some may believe that at one point, the robot-Maria was a dominant figure but I believe the robot was just a technological advancement to increase the view that women are seen as sexual objects. Why was the robot created in Metropolis in the form of a woman? This is a question that is portrayed in Huyssen's article. In my opinion, Rotwang wants to create a woman robot so he can have complete control over her actions. Huyssen even states, "After all, Rotwang creates the android as an artifact, as an initially lifeless object which he can then control." In creating a woman robot, Rotwang figures he can use her sexuality in order to receive the attention of the male workers. Power and dominance is what Rotwang wants and he found away to achieve it by the use of his creation. There are other males who display these dominant ways just as well as Rotwang does. Take the Master of Metropolis for instance. He orders Rotwang to create a robot in order to replace the human workers. He also has the control of all the workers because he is their employer. Now let us look at where sexuality and technology come into play in this movie. In the first part of the movie, Jon Frederson (the son of the Master of Metropolis) sees Maria for the first time. By the way he looks at her, you can see that he is having sensual feelings for her. Huyssen also expresses this idea in his article. In my opinion, Frederson does not really see her as the saint she is suppose to be playing, but only as an object that he desires and would like to pursue. As the movie progresses, Rotwang decides he is going to capture Maria and take her as a prisoner in his home. He does this so he can create a robot that exactly duplicates the features of Maria. As a result of this creation, technology is now mixed with the sexuality that Maria had inside of her in order to obtain control and power. The robot-Maria, uses her sexuality to obtain the attention of all the male workers.

The New Community: MMORPGs and Social Networking Essay -- Social Netwo

Community is changing. As far back as the twentieth century, a social community was a group of real life acquaintances that had a common interest, goal, or career. Back then, to update one’s â€Å"status† might mean to attempt to improve a person’s social standing within a particular community or group of friends. Today, people don’t need to be told what online social networking is. It’s so engrained into the current culture that people almost can’t remember how they interacted before the internet came along. How did people keep in touch? How did they interact and socialize and play? Before social networking sites like Facebook existed, people had to rely on the email, now the cultural norm for written communication. And prior to that, people had to send letters, an ancient form of communication that, believe it or not, involved rubbing graphite on paper to create a message, and then paying a courier to take it to your intended recipient, sometimes taking days or even weeks. Communicating took a bit more effort, and, in fact, so did recreation. To play together people had to meet up in something called â€Å"real life† and interact. For example, there were fantasy role-playing groups that played games like Dungeons and Dragons back in the 1980s and 1990s, but those cultures too have moved to the internet and amassed a huge following. Massively multiplayer online role playing games (MMORPGs, or MMOs for short) are part of a new emerging subculture that has already swallowed millions of people into a relatively new social gaming experience. Fantasy and science fiction universes have been created by artists and programmers, and the subscribers (usually via monthly subscription fees) create an online avatar that exist in new, massi... ....org.
