Changing Concentration of Hydrochloric Acid

Changing Concentration of Hydrochloric Acid How will changing the concentration of hydrochloric (HCl) acid affect the rate of hydrogen gas (H2) production during the reaction with magnesium (Mg), using the pressure buildup by hydrogen gas? Introduction Factors that influence rates of reactions include change in concentration, temperature, surface area, or the addition of a catalyst. This experiment will specifically investigate the effect of concentration change of the reactants upon the rate of reaction, using hydrochloric acid and magnesium strip. The concentration of HCl acid solution is controlled through serial dilution. 2HCl(aq) + Mg(s) à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ MgCl2(aq) + H2(g) This experiment in particular will explore how the pressure changes as the above reaction proceeds. Because the reaction produces hydrogen gas as a product, building up more pressure within the confined space of a test tube, a pressure sensor will measure the rate of reaction. After the reaction begins, approximately 20 seconds of data will be collected with each trial, in order to formulate a common trend (a graph of pressure over time). With average slopes of different amount of concentrations, a linear regression line will then be created to sketch the trend, regarding the effect of concentration upon pressure-the rate of reaction. Hypothesis According to Collision Theory, the reactant particles must collide together, and thus creating a reaction. Because increasing the concentration of HCl acid solution also means an increase in the number of hydrogen and chloride ions, collision between the reactant particles increases as well, resulting in more products-hydrogen gas. With more production of hydrogen gas in the confined test tube, pressure will build up. Therefore, if-at a given period of time-the concentration of HCl acid solution increases, then the rate of reaction will increase accordingly, because more collisions will occur, producing hydrogen gas at a higher rate. Variables Variable description Method of measuring variable Dependent variable Pressure buildup due to the reaction between hydrochloric acid solution and magnesium During the reaction, H2gas is produced, thus increasing the volume within the confined space of a test tube and increasing the pressure. This change will be recorded by a pressure sensor. Collecting data for about 10 seconds before the injection of the magnesium strip, the measurement of pressure will continue for about 20 seconds after the reaction begins. Three trials are required for each concentration of HCl solution to minimize random error. Rate of reaction Using the more accurate initial rate of the reaction, about 10 seconds of the graph after the reaction begins will be used to create a slope of change in pressure over time. Independent variable Concentration of HCl solution Using serial dilution along with apparatus such as micropipette and flask, the 1M hydrochloric acid solution will be diluted into 0.5M, 0.25M, 0.125M, and 0.0625M. Controlled variables Mg strip (length) Using a ruler and scissor, the Mg strip will be cut into 15 pieces, each being 1cm. Volume of hydrochloric acid solution For each concentration, 3cm3of hydrochloric acid solution is used, accurately measured by a pipette. Temperature of reactants The temperature remains constant at room temperature (approx. 25 degrees Celsius) throughout the entire experiment. Shaking of the test tube To create the most accurate results possible, physical motion when slightly shaking the test tubes must be repetitive in the same way for each trial. Size of the test tube Because different sizes of test tubes would mean different volumes as well, constant size (volume) is essential, preferably small so that the reaction will be more conspicuous. To do this, 15 identical test tubes are used. Table 1: List of Variables Apparatus and Materials 1M hydrochloric acid solution Distilled water Magnesium strip Flask (50cm3) Pressure sensor Logger Pro Micropipette 15 identical test tubes Sandpaper Scissor Procedure Put 20cm3 of 1M HCL solution in the flask and dilute it to 0.5M with 20cm3 of distilled water. Using the serial dilution as in step 1, prepare 10cm3 solutions with concentrations of 1M, 0.5M, 0.25M, 0.125M, and 0.0625M. Add 3 cm3 of each solution into labeled test tubes using the micropipette. Repeat step 3 to prepare three test tubes of each solution (15 in total) Cut out the magnesium strip into 15 pieces of 1cm and sand them with sandpaper. Put the cut out magnesium strip into the test tube with 1M HCl solution. Then quickly cover the test tube with the pressure sensor. Start collecting data while shaking the test tube in a consistent manner for about 25 seconds after the reaction begins. Repeat steps 6 to 8 for all other test tubes. Data Collection and Processing Qualitative Data After the injection of the magnesium strip into the HCl solution, it effervesces and pressure inside the test tube begins to build up. With test tubes of higher concentration, the pressure seems to be higher within the time limit and more bubbles form. At the end of the reaction, the solutions color changed to transparent yellow. The reacted solution (product) gives off a foul smell. Processed Data Data Presentation 1 0.5 0.25 0.125 0.0625 Uncertainties Standard Deviation Standard deviation was calculated and represented in the rate of reaction vs. concentration graph as error bars. Standard deviation for different concentration of HCl solution Standard deviation was calculated by a graphing calculator. Uncertainty due to the serial dilution of HCl solution Uncertainty due to 1cm3 Uncertainty during dilution measuring pressure (?) Conclusion In Figure 1, the trend of different concentrations of reactants influencing the rate of reaction is illustrated. The linear regression line demonstrates the clear change in rate of reaction, according to the change in concentration-the lower the concentration, the slower the rate of reaction. Hence, the initial hypothesis, stating the direct relationship between concentration and rate of reaction, is justified and validated. Evaluation Shown by Table 4, in which the standard deviations for each concentration of HCl solution are calculated, the results of this experiment are fairly precise, but not to a great extent. Moreover, uncertainties created during the preparation of the experiment, as with the management of apparatus and materials such as the gas pressure sensor, flask, and micropipette decreases the accuracy. Although Figure 1, the graph containing the general trend of concentrations effect upon the rate of reaction seems to validate the hypothesis, the rate of reaction of 0.25M HCl solution stands out of the trend, decreasing the validity of this experiments results. More factors that may have hindered obtaining accurate results of this experiment include: Error Impact Improvements Using hand to shake the test tubes for faster reaction rate Any non-perceptible (by humans) changes influenced each reaction to proceed differently, ultimately creating different circumstances for each trial. This change in circumstances is crucial since it greatly hinders accurate results. The use of a vibration plate instead may reduce error as it is more consistent. Reproducible circumstances can be better achieved.

Is Volunteer Tourism Defeating The Point Tourism Essay

Is Volunteer Tourism Defeating The Point Tourism Essay Volunteer tourism is described as the modern phenomenon of travelling overseas as a volunteer (Guttentag 2009: 538), which is exactly what I did in March of 2010. Eleven senior students from my secondary school were chosen to partake in a humanitarian mission trip to the Dominican Republic. We, along with our school chaplain and two teachers, worked with a local organization called Asociacià ³n para el Desarrollo de San Josà © de Ocoa, Inc. (ADESJO), and they sent us on a two hour trip up a bumpy and steep mountain to the village of El Cercado. For two weeks we worked on building ten latrines in the village while getting to know the villagers and making friendships and memories that we would carry with us for the rest of our lives. There is no doubt that as a volunteer tourist I took away a great deal from this trip, but I have begun to wonder what impact volunteer tourism has on host communities and the world at large. After researching the topic of volunteer tourism I have come t o discover that most of the benefits of volunteer tourism are felt by the volunteers themselves and not the host communities and their members. In the area of Global Development Studies this reflects the influence that the Global North has upon the Global South. Even though volunteer tourism is veiled by altruistic intentions, any positive effects could potentially lead to extremely negative effects in the global spectrum. Unsatisfactory work is being done by unskilled volunteers, cross-cultural misunderstanding and cultural stereotypes are being increased and reinforced, and neo-colonialism and capitalism are being supported. This paper will argue that volunteer tourism is more beneficial for the volunteers themselves, while in reality it has negative effects on the locals in host communities. While there are potentially macro scaled negative effects of volunteer tourism, it is important to analyse the initial micro negative effects that lead to these larger negative effects. The first and most important of these micro effects is that unsatisfactory work is being done by unskilled volunteers, while the needs of locals are put aside to focus on the experiences of the volunteers. In recent years volunteer tourism has become very popular, especially among post-secondary students (Bailey and Russel 2010 :353), automatically one is left to question the level of experience these students have in the areas such as infrastructure, education, or environmental conservation. Daniel A. Guttentag (2009) points out that there is a hindrance in work progress and the completion of unsatisfactory work, caused by volunteers lack of skills; (537) and there is even a decrease in employment opportunities (ibid.). It is evident that a great number of volunteer tourists lack certain skills which is undoubtedly due to the fact that they ..do not have enough knowledge, reflection capacity, appropriate skills or qualifications, volunteering and international experience, time to get involved with the locals or altruistic intentions (Palacios 2010: 2). Despite these facts the volunteers experiences are still focused upon. Organizations that plan volunteer tourist trips focus on making the experience of the volunteer tourists trip as enjoyable and safe as possible and work around the needs and desires of the volunteers (Guttentag 2009: 539). Even though some would argue that organization choose volunteers carefully and train them beforehand (Tomazos and Butler 2009:13), this cannot be generalized to all organizations. When the needs and desires of the locals are being ignored in order to service volunteers this negatively affects the lives of the locals in the host communities for they are the people that must endure the potentially poor work done by the volunteers. Volunteer tourists are described as experiential or experimental' (Bailey and Russell 2010: 3), and those two words automatically imply the word different. Volunteer tourists want to experience a different culture in order to grow and re-evaluate who they themselves are as a person (ibid.). Once again the volunteer is experiencing a benefit , but one is left to question what preconceived notion the volunteer has of the culture he or she is entering in to. Another issue that arises with volunteer tourism is that volunteer tourists that arrive in host communities in the Global South with stereotypical ideas increase and reinforce cultural stereotypes and cross-cultural misunderstanding (Raymond and Hall 2008:1). The preconceived notions of the volunteer tourists risk being stereotypical ideas of an impoverished and hungry family living in a shack, which creates a separation between themselves and the locals they come in contact with. If that separation is never bridged, or if the volunteer never gains a true knowledge of the culture because they are too focused on helping the stereotypical other, it creates and enforces cultural stereotype, especially because volunteer tourists may assume that host communities accept their poverty (Raymond and Hall 2008: 2). If there is a lack of communication between the volunteers and the members of the host community then the volunteer gains little to no true experience with the culture they are expe riencing, which can actually negatively impact the host culture (Guttentag 2009: 547). This problem is partly due to how the cultures are being portrayed by organizations. Reflecting true Eurocentric ideals (the notion that the correct way of living is the Western way and all other ways are exotic and irregular), organizations tend to portray volunteer tourist destinations in a way that will attract the volunteer tourists to participate in these excursions. A gap year is defined by the Oxford English Dictionary as a period of time (usually an academic year) taken by a student as a break from formal education, typically between leaving school and starting a university or college course, and often spent travelling or working (2010). There are organizations that specifically service these gap year students, but they are criticized for: [imposing] a simplistic view of the other so that difference can be sold and consumed. This occurs through the use of sweeping generalisations of destination communities in promotional materials and continues throughout the VTP [Volunteer Tourist Programs] due to lack of critical engagement with the experience. (Raymond and Hall 2008: 3) This simplistic view is meant to enhance the difference between the volunteer tourists and the locals of the host community in order to enhance the volunteers experience, but this is detrimental because it only reinforces Third World stereotypes and has the potential for romanticisation of the other stereotype (Matthews qtd. In Ooi and Lang 2010:3). Once again, the volunteers are benefiting from their experience as volunteer tourists, but it comes at the cost of the people of the Global South who must endure further victimization and stereotypes that create the idea that they must be saved by the Global North because the inequalities between the developed and developing worlds [are highlighted] (Simpson qtd. In Ooi and Land 2010:3). These inequalities reflect global capitalism and neo-colonialism. Poor work quality and issues of cross-cultural misunderstanding and the reinforcement of stereotypes all in the name of the volunteer tourist experience leads to macro-scaled problems of neo-colonialism and the support of capitalism. The Oxford English Dictionary defines neo-colonialism as the use of economic, political, cultural, or other pressures to control or influence another country; especially the retention of such influence over a developing country by a former colonial power (2010), and, broadly defined, capitalism is a system having accumulation at its core (Lippit 2007:179). Volunteer tourism is a new way of exploiting the Global South for the gain of the Global North because, as previously mentioned, the needs of the volunteers are focused on despite the fact that poor quality work is being done and it reinforces the notion of the other in order for the volunteer tourists to gain personal experience. Volunteer tourist trips support the notion of the other and reinforce po wer inequalities and thus represent a form of neo-colonialism or imperialism with respect to developing nations (Raymond and Hall qtd. In Ooi and Laing 2010:3). These power inequalities reflect capitalism because it puts the Global South at the bottom of global hierarchy, where they are used in order for those in higher positions the Global North to accumulate money and in this case, to accumulate global experience. This global experience is being gained at the cost of creating a gap between the North and the South in terms of advancement in technology and power, further supporting capitalism. This is reflected in what Guttentag (2009) has termed as the demonstration effect, a term that signifies how a host culture is impacted when tourists draw attention to their lifestyles and items of wealth (11) which leads to the possibility of locals trying to imitate the tourists consumption patterns, and discontent can emerge when these items of wealth are beyond the reach of a host community (ibid.). When attention is drawn to what the volunteer tourists from the Global North have and what the locals of the Global South do not have, it also draws attention the amount of power and wealth that their home countries possess on a global scale. Even now, organizations are aiming to attract the privileged volunteer tourists (Lyons and Wearing 2008: 187), which only increases the gap between the developed and t he underdeveloped, the rich and the poor, capitalism and equality. This inequality between these two worlds has a long history of colonialism, and although that ended after centuries of suffering and exploitation volunteer tourism is arguably a new form of colonialism. Volunteer tourism could possibly degenerate into a voyeuristic exploitation of the cultural other that masquerades as academic sanctioned servant leadership' (Butin qtd. In Sin 2009: 484). The Global North displays altruistic intentions of helping the people of the Global South, while in reality they are exploiting them for their own personal gain which is to train youth to become more socially aware and active, but this only leads to further dependence of the South on the North to repair their problems and ease their hardships. The North remains at the top of the global hierarchy: The basis conclusions of many authors that have contributed to this critical theory of development is that the Western intention of helping underlying the development aid goal as humanitarian as much a colonialist. However , it tends to reproduce the same global patterns of inequality and poverty. Leaving intact if not reinforcing the dominant position of the North. (Escobar et al. qtd. In Palacios 2010: 4) Neo-colonialism, the new form of colonialism, defeats the purposes of all of the fighting that occurred in to end colonialism, while once again the Global South faces the negative consequences of being exploited by the Global North through volunteer tourism. Despite the macro- scaled negative effects that volunteer tourism has the potential of causing, many defend its benefits. Volunteer tourism can enhance civic-related knowledge, skills, attitudes, and behaviours, improve interpersonal skills and emotional regulation, and contribute to better academic performance and meaning in life (Billig et al. qtd. In Bailey and Russell 2010: 3). Also argued is that: the volunteer tourism experience is a direct interactive experience that causes value change and changed consciousness in the individual which will subsequently influence their lifestyle, while providing forms of community development that are required by local communities. (Wearing 2001: 2) Unfortunately, it is evident here that the focus is primarily upon what the volunteer tourists gain from the experience, not the locals of the host communities. These benefits are indeed positive, but mostly for the volunteers and the country that they come from. It is arguable that when the volunteer tourists gain more awareness about these social issues and gain more of a feeling or a desire to make a difference then this will lead to them making a difference in the Global South. However, this is not completely positive because it aids in making the Global South dependent on the Global North. This also reinforces the stereotype of an impoverished and disease-stricken Global South that is doomed unless they are saved by the hero that the Global North has been portrayed as. There is still the argument that volunteer tourism appears able to offer [an] alternative direction where profit objects are secondary to more altruistic desire to travel in order to assist communities (Wearing 20 01: 12) , but this can be an example of the desire for profit being hidden under a veil of altruism there truly is no way knowing whether or not the intentions of volunteer tourists are purely altruistic or driven by egoistic ambitions. Despite the many negative issues that volunteer tourism brings into light, there are attempts to minimise them. Firstly, problems concerning poor work quality done by inexperienced volunteers are being addressed by organizations that offer training to their volunteers that must go through a difficult selection program to begin with (Tomazos and Butler 2009:13). Organizations are also attempting to involve locals in the host communities as much as possible in the work that volunteer tourists are doing, which creates more employment and helps the locals continue with the projects after the volunteers leave (ibid.). Secondly, in an attempt to reduce cross-cultural misunderstanding and the reinforcement of stereotypes, more and more organizations encourage their volunteers to be culturally sensitive and learn from their experience creating understanding and tolerance for other people and cultures (ibid.). Finally, there is a strong desire and attempts to make volunteer tourism beneficial in a way that it teaches others to travel responsibly, especially in regards to the environment, through what has been termed as justice tourism and solidarity tours (Lyons and Wearing 2008: 187) . These forms of tourism aim to move tourists to engage with the lived reality of the locals and to establish interactions based on equity and respect (ibid.). Evidently, there is an attempt to foster more positive effects of volunteer tourism in order to better serve both the volunteers and the locals. To conclude, volunteer tourism is portrayed as being driven by altruistic intentions, however it is evident that the volunteer tourists themselves experience more benefits than do the locals of the host communities. This issue must be addressed because it emphasizes the long standing notion that the North is the only hope of the South in order to be saved from poverty, disease, environmental crises, and even debt, which is actually the exact opposite of what so many theories in this course have implied. The negative consequences of volunteer tourism questions the intentions of volunteers and the organizations that send them, and also questions the intentions of transnational corporations and governments that have come to form global capitalism. Is the intention specifically to always keep the Global South at the bottom of the global hierarchy in order to reap the benefits of the cheap resources that continue to flow from those areas in order to service the lives of the wealthy North? This question can be argued to no end, but there is no answer as straight forward as the fact that even in volunteer tourism the needs of the Global North are put ahead of those in the Global South, while the Global South continues to suffer on too many levels.

Social Psychology Essay -- Psychology, Natural Science

There are many explanations for the origins of modern social psychology. It is therefore important to consider that social psychology cannot be traced back to one single source of origin (Burr, 2003). Hence, this is the reason why there are debates of what social psychology is. Allport (1985) described social psychology as the study an individual’s thoughts, feelings, and behaviours which are influenced by the actual, imagines, or implied presence of others. As seen from this definition there is a direct link between social science and the individual psychology (Sewell, 1989). Social psychology cannot be seen as a linear phenomenon. This is because social psychology has been derived from a combination of influences. The development of social psychology can be discussed in two different ways. Firstly, social psychology is argued to be found upon political movements and social philosophies in the United Stated of America (US). Secondly, it can be argued that social psychology ha s developed in response to social and political needs. There have been debates regarding whether social psychology should be dealt as a natural science or not. The ideology of natural science is very important as it affects the way the social psychologist deals with the situations. For example, if there are specific scientific objectives then the study can be laboratory based and use experimental procedures in order to gain knowledge. Psychologists who use this positivistic method are classified as experimental social psychologists. On the other hand, critical-social psychologists have competed with the experimental-social psychologists. The strength of the critical-social psychologists is that they’ve used a range of different methods in research, and have... ...ocial psychology now has a great impact on social cognitive approach. Social cognition includes attribution, stereotypes, autism, (Striano & Reid, 2008). The European roots of social psychology have led to social constructionism and social representation. The modern social psychology is now constructed with the American and European doctrines. However, due to the political events and developing researches in social psychology, the disciple has only been able to contain within America (Cartwright, 1979). On the other hand, Gergen (1973) argued that social psychology cannot be interpreted as a science because social psychology is historically and culturally specific, which is the reason why the discipline is continuously changing. Critically speaking, there is an advantage of different approaches to social psychology, as it views dilemmas in different perspectives.

The Life of Ludwig Van Beethoven :: Biographies

The Life of Ludwig Van Beethoven The rise of Ludwig van Beethoven into the ranks of history's greatest composers was paralleled by and in some ways a consequence of his own personal tragedy and despair. Beginning in the late 1790's, the increasing buzzing and humming in his ears sent Beethoven into a panic, searching for a cure from doctor to doctor. By October 1802 he had written the Heiligenstadt Testament confessing the certainty of his growing deafness, his consequent despair, and suicidal considerations. Yet, despite the personal tragedy caused by the "infirmity in the one sense which ought to be more perfect in [him] than in others, a sense which [he] once possessed in the highest perfection, a perfection such as few in [his] profession enjoy," it also served as a motivating force in that it challenged him to try and conquer the fate that was handed him. He would not surrender to that "jealous demon, my wretched health" before proving to himself and the world the extent of his skill. Thus, faced with su!ch great impending loss, Beethoven, keeping faith in his art and ability, states in his Heiligenstadt Testament a promise of his greatness yet to be proven in the development of his heroic style. By about 1800, Beethoven was mastering the Viennese High-Classic style. Although the style had been first perfected by Mozart, Beethoven did extend it to some degree. He had unprecedently composed sonatas for the cello which in combination with the piano opened the era of the Classic-Romantic cello sonata. In addition, his sonatas for violin and piano became the cornerstone of the sonata duo repertory. His experimentation with additions to the standard forms likewise made it apparent that he had reached the limits of the high-Classic style. Having displayed the extended range of his piano writing he was also begining to forge a new voice for the violin. In 1800, Beethoven was additionally combining the sonata form with a full orchestra in his First Symphony, op. 2. In the arena of piano sonata, he had also gone beyond the three-movement design of Haydn and Mozart, applying sometimes the four-movement design reserved for symphonies and quartets through the addition of a minuet or scherzo. Having confidently proven the high-Classic phase of his sonata development with the "Grande Sonate," op. 22, Beethoven moved on to the fantasy sonata to allow himself freer expression. By 1802, he had evidently succeeded in mastering the high-Classic style within each of its major instrumental genres-the piano trio, string trio, string quartet and quintet, Classic piano concerto, duo sonata, piano sonata, and symphony. Having reached the end of the great

Workplace Spirituality :: Religion, Work

Workplace spirituality is a sophisticated concept (Kinjerski & Skrypnek, 2004). Generally speaking, it involves the sense of well-being, the feeling of the whole self involved in the work, the feeling of connection to others and something larger than oneself, and a sense of transcendence (Ashmos & Duchon, 2000; Ingersoll, 2010; Kinjerski & Skrypnek, 2004; Kinjerski, V. M., & Skrypnek, 2008; Rego & Pina e Cunha, 2008; Sheep, 2004). Individuals view their work as sacred (Ingersoll, 2010), while workplace spirituality is not necessary related to religion (Ashmos & Duchon, 2000; Krishnakumar & Neck, 2002; Milliman et al., 2003; Rego & Pina e Cunha, 2008). It can be regard to personal value or philosophy. This concept can be referred to self-actualization proposed by Maslow’s (1954) hierarchy of needs. Besides pursuing satisfaction of the basic levels in the hierarchy, individuals have desire to satisfy the higher level of need. Although earning money is the basic goal, individuals eager to find out the meaning in work, to make contribution to the society, to reach their full potential, to become connecting with colleagues, to work in an organization which they identify its goal and value (Kinjerski & Skrypnek, 2004). Although a consistent definition in workplace spirituality has not been reached, mutuality in its definition delineated in literatures can be easily found. Sheep (2004) has been summed up into four themes. The first theme is self-workplace integration, that is the immersion of whole self into work. The second theme is meaning of work. People tend to find out meaning in their work. The meaning may be related to personal value, such as contributing to society and others, and go beyond monetary benefits. The third one is transcendence of self, connecting to something larger than self. This theme includes the connectedness to others, community, and the organization. The final theme is â€Å"personal growth and development of one’s inner life at work†. Organization can provide conditions for the growth and development of employees. Despite various perspectives about workplace spirituality, three dimensions were focused in the present study. The model proposed by Milliman et al. (2003) was adopted. In this model, workplace spirituality includes three levels, namely individual, community and organization. This model embraces two above mentioned theme such as meaning of work and transcendence of self. In the individual level of workplace spirituality, meaningfulness in work is involved in this level. People are motivated to actively search for and give meaning to their lives (Ashmos & Duchon, 2000; Frankl, 1992; Lips-Wiersma & Morris, 2009).

Back to the Future: Past, Present, and Future Essay

There is much to discuss and analyze about all three installments. These would include actor choices, spotting, direction, acting, and most importantly the soundtrack and musical choices for all 3. Considering all 3 movie plots jump from decade to decade, it can be analyzed literally from past, present, and future. Inevitably, Back to the Future’s success also led to several video game launches, a ride at Universal Studios in Hollywood and Orlando, an animated series, and even a comic book. Let’s go back to the year 1985, you and your bodacious friends want to hang ten with the dudes, so you guys catch a flick at the local cineplex. Your choices are Mask, Teen Wolf, or Back to the Future. You mean the guy from Family Ties? So you take your chances on Back to the Future. Good choice! Of all things, Eric Stolz, the main actor in Mask, was originally cast for the role of Marty Mcfly when production of Back to the Future began on November 26,1984. Stoltz was filmed for four weeks, but after seeing a rough cut, Steven Spielberg and the writer/directors decided that Stoltz had played the role â€Å"too seriously† for a comedy, and he was replaced by Michael J. Fox (Futurepedia). Back To The Future was written by Bob Gale and Robert Zemeckis, and mainly starred Michael J. Fox and Christopher Lloyd. The movie opened on July 3, 1985 and grossed $210 million at the US box office, making it the highest grossing film of 1985 (IMDb). The basic synopsis of Back to the Future 1, is about a young man named Marty Mcfly who accidentally travels into the past and jeopardizes his own future existence. With the help of an eccentric local scientist named Dr. Emmett L. Brown, he manages to travel back in time via a time machine made from a DeLorean. This was done by breaking the time barrier in what was called temporal displacement allowing it to travel along the space-time continuum. When the first script was made, a refrigerator was the planned prop for the time machine. Later Steven Spielberg decided he didn’t want kids trapped inside their refrigerators trying to play time traveling games (Funtrivia). Done carefully, Bones Howe (music supervisor) and Alan Silvestri (composer) gathered an array of perfectly fit songs to cater both the 1950’s as well as the 1980’s. The movie jumps from decade to decade throughout the movie, and makes it apparent when it does. The movie starts out when Marty is late for school, he gets on his skateboard and we hear a fantastic song by Huey Lewis and the News, the â€Å"Power of Love. Later in the movie, we hear another solid track by Huey Lewis entitled â€Å"Back in Time. † By the way, Huey Lewis makes a cameo as a judge. When Marty tries out for the school competition, Huey says, â€Å"hold it. hold it†¦ I’m afraid you are just too darn loud. † This is also considered diagetic mus ic in the film. Marty’s first time travel sent him to the year 1955. Marty, immediately, arrives at the Twin Pines Ranch, which was owned by Otis Peabody. Marty crashes into the barn on Mr. Peabody’s property which causes the entire Peabody family to wake up and come outside. Marty encounters many differences between 1985 and 1955, including a cleaner, less run-down ambiance in the Courthouse Square. While searching for a younger Doc Brown, he meets his father and accidentally interferes with the first meeting of his parents–being hit by his grandfather’s Chevrolet in his father’s place. While in the 1950’s, some of the songs we hear are such great classics â€Å"Night Train† by Marvin Berry, â€Å"Earth Angel (Will You Be Mine)† by Marvin Berry, â€Å"Wallflower† by Etta James, and â€Å"Johnny B. Goode† by Chuck Berry aka Marty Mcfly. Some people complained that Back to the Future was a racist movie because Chuck Berry was inspired by a white guy. Sometimes a joke is just a joke; but Chuck Berry liked it. (Davis). Finally we have the sensational score by Alan Silvestri. At times the score is adventurous, and at times it’s sad. The spotting is done just right to balance the dynamics of the movie. Also, there is a leitmotif that accompanies the movie, in fact, it accompanies all 3 movies of the trilogy, and never goes unnoticed. Upon the success of the first film, Robert Zemeckis (director) and Bob Gale (writer) agreed to do a 2nd movie. In fact, they also intended on a 3rd movie, and both the 2nd and 3rd Back to the Future were filmed simultaneously and released six months apart. Back to the Future 2, with a budget of $40 million, grossed nearly $331 million at the box office (IMDb). The characters of George Mcfly and Jennifer Parker were played by different actors from those in the first film, requiring scenes that overlap to be re-shot. Jennifer Parker which was originally played by Claudia Wells, and replaced by Elisabeth Shue in the second film. Claudia claims she turned the roll down when she found out her mother was diagnosed with cancer (Futurepedia). George Mcfly, who was originally played by the quirky Crispin Glover, was later replaced by Jeffrey Weissman. Crispin Glover refused to return to the trilogy due to salary disputes. Back to the Future 2 pans back and forth from 1955, to 1985, and all the way to 2015; the past, present and future. Needless to say, Bob Gale and Zemeckis attempted to predict what 2015 would like and sound like. Some songs used in the 2015 scenes, were â€Å"Beat it† by Michael Jackson, â€Å"I Can’t Drive 55† by Sammy Hagar, â€Å"Mr. Sandman† by The Four Aces, and â€Å"Papa Loves Mambo† by the Perry Como. The filmmakers did do some research into what scientists thought may occur in the year 2015. Bob Gale also commented; â€Å"We knew we weren’t going have flying cars by the year 2015, but God we had to have those in our movie. â€Å"(Q ;amp; A) The film was also considered one of the most ground-breaking projects for Industrial Light ;amp; Magic. It was one of the effects house’s first forays into digital compositing, as well as the VistaGlide motion control camera system, which enabled them to shoot one of the film’s most complex sequences, in which Michael J. Fox played three separate characters, all of whom interacted with each other. Although such scenes were not new, the VistaGlide allowed, for the first time, a completely dynamic scene in which camera movement could finally be incorporated. The technique was also used in scenes where Thomas F. Wilson’s character (Biff Tannen) had to interact with a younger version of himself. (Zemeckis) Six months after Back to the Future 2 was released in the theaters, the Back to the Future team released Back to the Future 3 on May 25, 1990. Again on a budget of $40 million, this one cashed in at $244 Million. The film takes place immediately after the events of Back to the Future Part II. While stranded in 1955, Marty McFly discovers that his friend Dr. Emmett â€Å"Doc† Brown was killed by Biff Tannen’s great-grandfather Buford. Marty decides to travel to 1885 to rescue Doc and return to his own timeline. This time, Alan Silvestri had to create his soundtrack based in the year 1885. However, he still maintained the leitmotif throughout the picture. The years 1985 and 1955 are still relevant in the 3rd movie, and it jumps around. The popular group ZZ Top make an appearance, as they perform â€Å"Doubleback† during a festival in 1885. This was also considered diagetic —-performed for the actors and the audience to hear. Huey Lewis’ â€Å"Power of Love† is also heard again. In 1989, a video game, based on the original Back to the Future movie was produced for the 8-bit Nintendo Entertainment System (NES) by video game publisher LJN a subsidiary of Acclaim games. This has some similarity to the 1983 Atari video game E. T. where producers felt it would sell solely on brand association to the hit movie and the game designers were only given five weeks in order to produce a product to get it on the shelves for the 1982 Christmas shopping rush. Reviewers also cited that game as virtually unlike the film and was a major contributor to an economic downturn known as the Great Video Game Crash of 1983. There are only two songs found in the entire game. One is â€Å"Johnny B. Goode† which will play during the school dance that Marty is playing on stage and sounds close to the version heard in the film. The other song is a repetitive looping song that will play throughout the game in non-mini game moments. There are suggestions that the song is supposed to be â€Å"The Power Of Love† by Huey Lewis ;amp; The News sped up and cycled differently. But it winds up sounding nothing like the actual song made famous in the movie. Nes also later released Back to the Future 2 and 3 as a single game in 1990. Back to the Future II ;amp; III received largely negative reviews from critics. Stan Stepanic of Gamefreaks365. om gave the game positive remarks in regards to similarities with The Goonies II, but gave it a largely negative review due to the lack of a password or save feature coupled with its notorious length, although there was a code to skip to the second half of the game. Back to the Future II ;amp; III’s length has often been cited as the game’s major weakness, Stan stating that it took him roughly six hours just to map it, and he spent so much time trying to fini sh it he actually turned it off out of boredom. (Gamefreaks). Sega Genesis also released their own version of Back to the Future 3 in 1991. It was a lot different than the Nintendo version. However, it was just as unpopular, the opening level was nearly impossible to complete. Finally in 2010, Telltale Games released Back to the Future on PC and Mac; and later was also released on the Ipad and Playstation 3. This was given way better reviews than the predecessors, and remains the best game of yet. Ben PerLee from GameZone summarized his praise of the game by saying it is a â€Å"feel good cinematic experience that any fan of Back to the Future will want to check out, and everyone else would do well to check it out. GameZone) Back to the Future: The Animated Series was an animated series based on the Back to the Future trilogy as well. The series lasted two seasons, each lasting 13 episodes, and ran on CBS from September 7, 1991 to November 28, 1992, the date of the last original episode. Harvey Comics also published a series of Back to the Future comic books starting in November 1991. With the cover header reading †Å"The Adventure Has Only Begun! ,† the first issue featured Doc & Marty in 1927 Chicago. On May 2,1991 the Universal Studios Theme park in Florida released Back To The Future: The Ride. It was a simulator ride based on the popular movie trilogy of the same name. It was a mini-sequel to Back to the Future Part III. Later at Universal Studios Hollywood, they opened the same ride on June 12, 1993 ; and then at Universal Studios Japan on March 31, 2001. The Orlando and Hollywood versions closed in 2007 (Futurepedia). Although Back to the Future creators Robert Zemeckis and Bob Gale had no involvement with the ride, they were consulted as to whether they â€Å"got Doc right†. The two responded with a â€Å"yes†. They have also commented that â€Å"it’s a great ride. In addition, references are made to a â€Å"Zemeckis-Gale diagram† and â€Å"Gale-Zemeckis Coordinates (Giveneyestosee) With the huge success of the Back to the Future Trilogy, you can see where a simple idea can turn into a big one. When you take risks on a new actor, and stamp something with a touch of great directing, production, and a great score —- you never know what could happen. Back to the Future will always remain a classic no matter what generation it leads to; whether it be 1955,1985, or even 2015. Works Cited â€Å"Back to the Future II & III Review. Review.

Why did Edward IV’s death cause a bitter power struggle in 1483?

Why did Edward IV’s death cause a bitter power struggle in 1483? Edward IV’s death caused many issues with regards to power shortly after he died because of many difficulties. This ranges from a complicated will, to the betrayal from his brother, Richard, Duke of Gloucester. Shortly before Edward IV’s death, he amended his will, and the only copy of the new will was ruined and nobody ever really knew what changes Edward IV made. Because of this, there was a bitter power struggle.This power struggle revolved around two competing factions, Woodville and Gloucester. Firstly, because of the issues with the will, there was no direct heir to the throne, and it was either going to be Edward V on the throne or Richard of Gloucester, nonetheless Edward IV’s son Edward V had to take the throne. However, because Edward V was a minor, the two factions competed to control the country until Edward V was old enough where he could govern by himself, thus resulting in a bi tter feud within the Yorkist family.This became such a struggle for power simply because Edward V’s mother, Elizabeth Woodville had such a great bond with her son, and also, because Richard, Duke of Gloucester truly wanted to become King. At the time of Edward IV’s death, both factions had their strengths and weaknesses. For the Woodville family, they had strategic advantages primarily because Prince Edward was with Elizabeth Woodville’s brother. Furthermore, Woodville’s brother was appointed ‘Governor and ruler of the Princes household’. The power and influence of the Princes counsel grew, and with it the status of the Woodville family.However, the Woodville family were seen as social climbers, and they were resented by members of established nobility, especially Gloucester, Hastings and Buckingham. Additionally, being seen a social climber in 1483 was practically as bad as sinning. This was perceived as a significant drain on the royal patr onage. For Gloucester, the strengths would be that he had the active support of two of the greatest magnates, the Duke of Buckingham and Lord Hastings. They were established enemies of the Woodville’s, having competed against Earl Rivers in 1471 for lieutenancy of Calais.Secondly, Henry Stafford was Gloucester’s most powerful ally. Buckingham had a remote claim to the throne, being descended from Edward III’s youngest son. Moreover, Lord Hastings was loyal to Edward V, but opposed the Woodville’s. The only weakness for Gloucester would be that Prince Edward was brought up almost entirely by members of the Woodville family, thereby feared by Gloucester as being more Woodville than York. The Woodville’s hoped for an early coronation on the 4th of May, as it would represent the end of Edward V’s protectorship and therefore undermine Gloucester’s position as protector.This would have been a clear, easy win for the throne for the Woodville family; however the Counsel could not make a clear decision for who to be protector. One section of the Counsel wanted Gloucester to be protector but the other section of the Counsel wanted a regency Counsel to include Gloucester. As tension brewed, Richard Duke, of Gloucester decided to end the entire struggle for power by bringing up past rumours of Woodville and Edward IV’s relationship issues.Richard, Duke of Gloucester always detested his brother Edward IV after his secret marriage to Elizabeth Woodville, as he was made to look a fool by him when he found out they was married. Furthermore, when society found out of this marriage, this almost put Gloucester at an advantage because in that century, the King was supposed to marry a person that would influence the Kingdom in a good way, not out of love. Nevertheless, Because of this, Gloucester revealed that it was rumoured that Edward IV was already married, when he was got married to Elizabeth Woodville.For this reason, t he marriage was deemed illegitimate, thus making Edward V’s inheritance of the throne illegitimate. This was a very strong move from Gloucester, and ultimately, because of this, he gained the throne, and the power to rule. To conclude, the whole situation of this bitter power struggle could have been completely avoided if Edward IV was not blinded by love. Edward IV should have made it clear whether it is his Son to rule or his brother, and not have left his wills conflicting with each other.
