Marcel Duchamp Pablo Picasso and Andy Warhole

The artistic exchange of ideas and influences can profoundly affect the art world'- Explore this statement with reference to a range of artists and artworks. Artistic exchange is a conceptual idea involving the exchange of artistic methods, ideas, and other elements of an artist's practice; and if an artist is a pioneer or an innovator, their ideas can resonate through exchange to transform the entire art world. Throughout the 20th Century the shaping of the art world came into play through ideas, expression, education and one result of this was the age ofModernism. There was much social ad political unrest sweeping through Europe, during the beginning of the twentieth century which contributed to the breaking of the traditional art barriers. The works of Pablo Picasso, Marcel Decamp and Andy Warhol strongly affected the art world with their individual yet diverse techniques and styles. These artists broke away from traditional art and its boundaries in order to exchange ideas and co nventions regarding the aesthetics which opposed accepted societal standards.These ideas were profoundly influenced the art world. Marcel Duchess's art making practice was characterized by its humor, variety, the unconventionality of its media and its persistent exploration of art's boundaries. Decamp was involved with the avian-garden movements during the Modernist period, and as an iconoclast, he abandoned these artistic principles, with the aim of rejecting convention such as his distaste for art that was pleasing to the eye'. Works exemplifying these beliefs include Bicycle Wheel (1913) and L. H. O. O.Q (1919) which caused controversy over their acceptance as ‘art'. Bicycle Wheel is a redeemed (a tool supporting an upside-down bicycle wheel) that Decamp has decentralized as well as displacing its original function, thereby transforming an industrial, mass produced object into a work of art. Duchess's art making approach could be considered satirical, as it often ridiculed the ideals established by society. L. H. O. O. Q is an altered postcard of the Mona Lisa that Decamp has satirized by drawing a moustache and goatee on the face of this iconic figure.This notion of ‘defacing' a Ad Vinci masterpiece was very shocking to the art world during the early 20th century, revoking controversy as it was not handmade, but redeemed and ridiculous, thereby questioning what really defined art. The avian-garden character of Duchess's work influenced the art world by encouraging the critical question of what constitutes art. The influence of Duchess's ideas an practice have been imprinted in many of the works of American modernist Andy Warhol.Whorl's Campbell Soup Cans (1962) and Marilyn 1962 build on Duchess's concept of the redeemed and have inspired a genre of artworks that employ the techniques of reclassification and appropriation. As a leading artist of the sass's Pop Art movement, Warhol was revolutionary in his appropriation of popular culture. Whorl' s work explored the processes of silk screening, and for the first time was using assistants to produce artworks. The process of silk screening enabled Warhol to investigate mass- production techniques, which is evidenced in his work through his use of repetition, cropping, overprinting and the use of the grid.Warhol used a â€Å"ready made† image of Marilyn Monroe from a commercial publicity shot, and then altered this appropriated image. Warhol plays with reclassification in a similar fashion to Decamp. Warhol takes this idea further than simply rejecting past values by persuading the audience to question the relationship between culture and the media, and to define the sass's perception of celebrity. Whorl's artworks mimic the processes and subject matter of mass production. This artwork signals a loss of individuality for Marilyn Monroe: she is a multiple and she is banal, yet Marilyn is symbolically a most potent American icon.Whorl's artworks, particularly portraits, ar e a social chronicle of the time. Whorl's work titled Campbell Soup Cans(1962) also stems from the concept of appropriation and the redefining of context. ‘Campbell Soup Cans' appropriates images from popular American culture, exploring the idea of combining art and centralization. Warhol has used polymer paint and silkscreen ink on plywood to replicate the once mass-produced sales product. In making this decision, Warhol has consciously blurred the line between art and consumerism.This particular concept had a profound impact on the art world due to its disputed classification as art – categorized by some as ‘merchandise'. The similarities between the thought processes of Marcel Decamp and Andy Warhol how a distinct exchange in artistic ideas, resulting in profound works which question the established standards of the art world. In exploring the evolution of these artists and their ideas, the profound impact and importance of artistic exchange becomes clear. Artw orks by Pablo Picasso show a clear breach of artistic boundaries to form new ideas.One of the most important roles in the development of modern art was Cubism. The origins of cubism started off with one of the biggest paintings that he had ever done and featured five women, each whose head looked as if it was on backwards. The painting was named Less Demolishes Davidson (1907). The five women portrayed were very ugly and distorted; causing controversy with the audience because they believed that it should have been depicted realistically and professionally, rather than â€Å"creating a mockery to art itself†.Picasso had broken all â€Å"the rules† while creating this painting, but his main goal was to paint the women from more than one angle at a time, hoping that the audience saw more than what meets the eye. This work was heavily criticized by the art world but Picasso broke away from convention, for what he believed was art. What made Picasso different from other ar tists of his time was that his art reflected his emotions in his personal life and the outside world. He was not afraid to push the boundaries reflecting on contentious and controversial issues such as war and peace.One of the issues that he painted from the Spanish civil war depicts a military revolt against the Republican government of Spain; which had polarize Spanish life and politics over previous decades. In April 1937, Germans who sided with the current dictator of Spain at the time, General Francisco Franco, bombed the town of Queering in northeast Spain, not far from where Picasso grew up. More than sixteen hundred people were killed and almost nine hundred more were injured.Outraged by the murder of all these innocent people, Picasso created his famous, Queering (1937), in blue, black, and white oil tones. The painting portrayed the suffering of people, animals, and buildings and the chaos. It showed a screaming horse, a fallen soldier, and a screaming woman on fire fallin g from a burning house and a mother holding a dead baby. According to Picasso, it was not up to the painter to define the symbols; otherwise, he would have Just written it in words. Queering overall represented the brutality of war in general.It's significant because people actually had to think about the image that they saw, and each perceived it in a different way. Picasso style of painting led people to look deep into the meanings of art rather than Just a superficial aesthetics. The audience were able to relate to Picasso tormented scene. Artistic exchange is a phenomenal act that allows ideas ad techniques to be shared between the art world and the audience. By comparing Marcel Decamp, Andy Warhol and the work of Pablo Picasso one can see how a visionary can affect the art oral.The many accomplishments of these artists not only impacted on the history of their time but the future of how the world saw art. They were involved in different movements in the art world which created a certain vitality for the artistic exchange of ideas and influences. The interchange of ideas and influences greatly affected Picasso , Decamp and Warhol , their artwork and their audiences. Artists shared artistic language allows them to build upon past concepts to produce innovative qualities which resonate through exchanges to greatly influence future generations of artists.

Competition – What do we mean by the Global Market place?

1. What do we mean by the Global Market place? Global means to introduce the company world wide. To make the company known to the whole world rather than just one country. 2. What is globalisation? Globalisation refers to the way a company sets out to operate in exactly the same way throughout the globe using the same packaging, the same products, the same adverts, etc., in every country in which it operates. 3. What is internationalisation? This refers to the way in which companies expand their operations overseas in order to exploit new markets. 4. To be competitive an organisation needs to make sure that it: * Provide quality products that meet customer requirements. * Values its people- the most important resource of any organisation. * Uses modern technology, including information technology, to its full potential. * Ploughs back funds into new investment, research and product development. * Experiments with new ideas and sets out to lead rather than follow the field. * Makes sure that it has outstanding customer and community relationships as well as respecting the environment. * Takes into consideration the requirements of all its stakeholders.

AN INVESTIGATION OF THE IMPACT OF GLOBALISATION TO THE MULTINATIONAL Essay

AN INVESTIGATION OF THE IMPACT OF GLOBALISATION TO THE MULTINATIONAL CORPORATION - Essay Example Josephine Bromme (2010) takes globalization to another level by relating to it as a compression of the social society. He suggests that globalization is the expansion of a company’s offering to other parts of the world and it takes international strategies for companies to expand their business at global level. Jorn Kleinert (2004) proposes that globalization has opened up a gateway for companies to flourish both on home and host countries. This has also helped society develop on cultural terms because when a product of one country is introduced to another country, distances and stereotypes are reduced and people become more open to acceptance. Globalization has helped multinational companies tap resources in host countries which have been unknown to the general society. Moreover, it has helped people fight in terms of competencies and skills in order to fulfill the standards set up by the multinational giants. Also it has made society a better off place. Globalization provide s an excellent outsourcing opportunity for multinational companies. When multinational companies make the most of the phenomena of globalization, they improve the economic, social, welfare and political condition of the countries where they invest. Research Method Sekaran, U. (2000) proposed primary research and secondary research as the most common and authentic methods of carrying out research. As mentioned in earlier sections of this research proposal, the purpose is to investigate how globalization has made it easy multinational companies to expand business and exploit resources. In order to do so, Coca Cola has been selected because this is one of the many trusted companies. Also it is one of the oldest multinational companies which has gained topmost image in the world of food and beverage business. For the purpose of carrying out this research, data is required from the internal as well as external customers of Coca Cola so that authentic results are obtained. I will be colle cting primary data from the employees as well as the customers of Coca Cola in the form of questionnaire. The questionnaire will be based on certain number of closed ended` questions which will be aimed at globalization and multinational companies’ relationship. It will be distributed to random customers at shopping marts and employees at various levels in the company. The sample size will be two hundred approximately because the more is the sample size of any research, more are the chances that the results obtained will be close to the term authentic because whenever researched through questionnaires is being conducted, large sample is gathered; a sufficient margin should be left for those respondents who fail to provide accurate information. It will not be difficult to gather data from customers present in marts because there are plenty of them and if not many, few will definitely show willingness to respond. The employees will be busy so it would take sometimes to get an a ppointment from them. After collecting the data, it

(Public Health) Provide and overview of the development of the public Essay

(Public Health) Provide and overview of the development of the public health movement from the Nineteenth Century to the present day., - Essay Example The major ingredients of an individual's health are nutritional, spiritual, intellectual and of course physical. Through the centuries, there have been various far-reaching and historic developments in this realm, which have made the health sector look like what it looks today. Some consider public health to be a contemporary concept, although it has its foundations way back in time. First, appreciating the essence of public health is important. It basically establishes parameters around the things we do in the world. This can be at the state level, at well at the societal level. However, the more integral thing to understand here is that whereas public health itself is ratified by the governing authority, yet it stems from within the values of the society itself. Thus it takes the form of a cycle, in which all entities become inter-dependent. Taking an imaginary starting point in this circle, the factors start to become prominent within a social group. These are then highlighted at the appropriate levels, and take a more potent form. Religious beliefs, superstitions, moral values, customs of service, all contribute to the same. The colonization that happened in the previous century is a very good example. All the European powers who administered their might over the rest of the world initially went in as economic traders. They stayed in that country for sometime, and tried to understand their emotional climate. Subsequently, they put actions to their thoughts, and militarized their expeditions. The impact of their stay on the now independent colonies is still visible. The places, which had the same culture and customs for centuries, now were changed immensely due to their new leaders. When people at appropriate levels begin to establish the true societal norms of a community, then half the job is done. But the other half remains a much more crucial and even controversial entity. If the established norms would have stayed the same all these centuries, then the world would not be witnessing so much disparity in today's date. The fact of the matter remains that there has been constant change in the paradigm of public health for various cultures. But the establishment of this change has not been easy. Sometimes, it has just taken the normal course of the 'time factor' wherein things gradually mould into the new shape. However, there remains a more abrupt and definitive means of change, which has met its opposition all this while. The reason is simple; as norms are largely based on people's beliefs, therefore so is public health, if anybody attempts to make any change in the same, then their action would be met with opposition. This is more so true in today's age, wherein the global village now exists beyond a metaphor. A person sitting in any part of the world can find about the customs and tradition of the other at an equally diverse area. The human body is susceptible to any new stimulus. Therefore, now people begin to look for common grounds as human beings, something that was only a dream only a couple of decades ago. Technology has brought new life into the concept of public health. Now terms like abortion and euthanasia may still be taboo in a place, but there would be people who will lend an ear if a movement regarding the same would be in process. This is a direct stance against the conventional system of policy based on values. Understanding, studying, analyzing and most importantly applying public health is therefore imperative for the growth and evolution

Discussion #1 APS 210 - Essay Example 2. The best security technologies for faith-based facilities are the least physically noticeable ones as they cause less obtrusion for the parishioners. These include inbuilt electronic door locks, access controls, hidden surveillance cameras, motion detectors and metal detectors. Security strategies include training the facility attendants on security surveillance, developing a sound emergency action plan, and enhancing instant communication systems for emergencies. 3. Before establishing the security enhancements for the places of worship, it is important to notify the parishioners and the surrounding community of the intended changes of the intended changes and their purposes. This step avoids any alarms and misunderstandings that may occur from security upgrades. 4. One similarity is that both cases receive protection from similar threats, which most of the times are terrorism and theft. A difference is that faith based organization facilities receive far more discreet protection measures, which impede on personal privacy on a much lesser scale the than U.S. Critical Infrastructures. Faith based organization facilities also receive protection on a much smaller scale in terms of monetary investments and level of expertise than the Critical Infrastructure locations (Harrell

Race in Turn of the Century America Essay Example | Topics and Well Written Essays - 500 words

Race in Turn of the Century America - Essay Example The problem of racial confusion was quickly becoming a serious issue, in the early twentieth century. This is because of the lack of a unified government, which would establish common grounds with racial equity and rights (King & Ruggles, 1990). After the end of the Civil War, eleven Southern States introduced national policies that further supported â€Å"the problem of color-line†, in relation to immigrants and African Americans, through the First World War. For example, ten southern states introduced laws prohibiting the mixing of races in ferries, railways, and steamboats (King & Ruggles, 1990). For instance, Atlanta, from 1908, introduced racially segregated elevators. Additionally, taxicabs were separated in Florida, Birmingham, Jacksonville, and Mississippi, Alabama. Similarly, it was illegal for Black and white baseball clubs to play, in proximity, in Atlanta (King & Ruggles, 1990). Change in welfare policy, after civil wars also promoted â€Å"the problem of color-li ne†. The Northern changed the social welfare policy to provide government assistances equally and help recipients become self-independence (King & Ruggles, 1990). This made the Southerners to further entrenchment of racism and slavery as a sign of disrespect to the Northerners, who defeated them in the civil wars. The Southern States that encouraged racism include Mississippi, South Carolina, North Carolina, Texas, Louisiana, Alabama, Georgia, Arkansas, Virginia, Tennessee, and Florida (King & Ruggles, 1990).

Global Talent Assignment Example | Topics and Well Written Essays - 250 words - 1

Global Talent - Assignment Example Becker, Huselid & Ulrich (2001) found that accessibility problems can arise in many forms including accessibility of value-added metric to acquire and accessibility of the value added by the metric after it has been acquired. In the current context, issue of accessing the value that the metric add to the organization after it has been acquired is what is being focused. In such a situation where there is lack of accessibility to value-added metrics, the first point of call in overcoming the situation should be the organizational structure. This is because where there is a bureaucratic and overly centralized organization structure, the flow of resources and even information across all quarters of the organization becomes highly limited. As a result of this, it is very difficult that all members within the organization can have a feel of the value added to the HR activity by the new metric. For example when the metric is used to collect data about employees, it could be that the outcome of such data will not be made known to the employees. In such a situation, chances are that employees can resist any future implementation of new metrics. This is because the employees will not have any basis on which they can justify or testify to the benefits of the metric. But where there is an open system being operated where the outcome of the value added by the metric is openly discussed, implementation will not be problem because all employees are likely to come on board and

McDonalds Business Strategy Essay Example | Topics and Well Written Essays - 9500 words

McDonalds Business Strategy - Essay Example By 1968, the chain comprised 1,000 units, which rose to 5,000 units by 1978. By 2001, the company operated around 30,000 units worldwide. Whilst keeping menus limited, McDonald's diversified its range from its original hamburgers and cheeseburgers. In 1964, the company launched its Filet-o-Fish sandwich, followed by signature burger the Big Mac in 1968, Happy Meals in 1979 and Chicken McNuggets in 1983. (Keynote, 2003; Leitch; 2004) While the majority of sales remain concentrated on burgers and fries, drinks and desserts are important and the brand periodically experiments with other menu additions, such as salads and local specialities. McDonald’s currently gearing up for the introduction of a new salad range in 2006. The late-1990s saw McDonald's shift its focus, as burger fast food, especially in the US, seemed dangerously crowded and mature. Consequently, McDonald’s focused on diversification, introducing new menu items and aiming to attract a more adult demographic, while retaining its core consumer base of children. 2000 saw the introduction of salads, low-fat desserts and a wider choice of chicken and fish burgers. The company also began to relax the McDonald's formula, introducing more regional menu variations and experimenting with new formats, such as cafà ©s and kiosks. This strategy of diversification also resulted in a number of acquisitions during the review period, seeing a shift away from its traditional single-brand focus. In 1998, McDonald’s purchased London-based coffee chain Aroma and in 1999 and 2000 McDonald’s purchased US chains Donatos Pizzeria with an emphasis on â€Å"home-cooked meal† style fast food. ... The company also began to relax the McDonald's formula, introducing more regional menu variations and experimenting with new formats, such as cafs and kiosks. This strategy of diversification also resulted in a number of acquisitions during the review period, seeing a shift away from its traditional single-brand focus. In 1998, McDonald's purchased London-based coffee chain Aroma and in 1999 and 2000 McDonald's purchased US chains Donatos Pizzeria (Ohio based), Mexican self-service cafeteria brand Chipotle (Denver based) and Boston Market with an emphasis on "home-cooked meal" style fast food. Beyond acquisitions, McDonald's also made a series of strategic investments. In February 2001, McDonald's acquired a minority interest (33%) in the British sandwich chain Pret a Manger. In 2002, McDonald's formed a joint venture with Fazoli's, a fast casual Italian restaurant concept based in Lexington, Kentucky, to develop 20-30 Fazoli's restaurants in the US. (Leitch; 2004) This also gave McDonald's the option to purchase the entire company at a later date. The company also opened its first multibranded unit, offering Boston Market, Donatos and McDonald's. However, these acquisitions did not prove wholly successful. In 2002, the company experienced a difficult year, culminating in its first ever quarterly loss. This poor performance was partly due to weak economies in Latin America and APMEA (Asia-Pacific, Middle East and Africa) and to increasing competition in mature US and Western European fast food. However, the company also felt that its strategy of brand diversification was d iluting its focus on core brand McDonald's. In 2002, Aroma was sold to Caff Nero and in 2003

Pseudophryne corroboree Assignment Example | Topics and Well Written Essays - 1500 words

Pseudophryne corroboree - Assignment Example A species recovery program was implemented to identify the processes that threaten species and formulate a definite strategy to properly address such threatening process and execute recovery actions. In March 1997, three P. corroboree populations were chosen for population augmentation: Dargal Range (Site A) population with 32 calling males, Jugumba Range (Site B) population with 13 calling males, and Round Mountain Range (Site C) population with 2 calling males. These sites were inspected after the breeding season to collect clutches for captive rearing at the Amphibian Research Center (ARC) in Melbourne. Sixteen nest out of 25 male nests in the three sites contained eggs. From the 16 nests, 374 eggs were gathered for captive rearing while 324 left in their respective nests for filed comparison. The highest level of mortality in the three field sites was observed during the over-winter stage, with total mortality in site B. For the captive-reared tadpoles, the highest rate of mortality was observed in the post-winter tadpole stage. The percentage of captive-reared animals survived was higher than the percentage survived at Site B, while there was no significant difference between the rate of survival for Site A and captive-rearing. Thirty-eight percent of the eggs collected from Site A survived through to metamorphosis as compared to 31% survival in the field (Hunter, Osborne, Marantelli, and Green 161). Fifty-three percent of the captive-reared animals survived through to metamorphosis, while Site B has no survivorship. Seventy percent of the captive-reared that was collected from S ite C has survived through to metamorphosis and only 13% of eggs left in the field survived (Hunter, Osborne, Marantelli, and Green 162). During the post-winter stage, the field tadpoles had higher rate of survival than the captive-reared animals, in which early release tadpoles exhibited higher survival rate than the

Four Truths and a Lie Essay Introduction†¦ Have you ever said a truth? Well, you say truth 99.8% of your conversation each day! You are most likely to said a truth by playing – truth, dare, double-dare, kiss, love game. On the other hand, have you ever lied? Obliviously, I think everyone have lied at least once in their life because they have to do it to helps themselves. Me, Kaitlyn Phan has 1 sister and 1 brother named Lana and Joe, and I live my mum and siblings here. I have 4 good friends named: Michelle Tsang, Chriselle Lee, Lindy Sohn and Melody Lim! I live in Singapore one of the busiest and crowed country (well, place) in the world. I have lived so many countries since my dad is†¦ Busy man!

Effect Of Design On Paper Plane

Effect Of Design On Paper Plane I have decided to write my extended essay on this topic because this activity of flying paper planes was taught to us in our childhood when we were not mature enough to learn the principles of science and investigate and apply them to these planes. But what caught my interest was that how do paper airplanes of such light weights can maintain their flight and speed even while facing winds and other external factors. Firstly, I had decided to write my essay based on the principles used in these planes, but my supervisor guided me that it was too broad and thus, I narrowed down my topic to- To investigate the difference in the flight of the paper planes and the distance covered by it due to the shape, mass and design of the paper planes. Introduction: Paper airplanes are a source of fun and entertainment for many people while they can also be used as a part of learning and gaining some amount of knowledge about the real aeroplanes. Some people have also named this activity as an art named aerogami which derives from the name origami (a Japanese art of paper folding). But, this so called entertaining and competitive activity has a lot of science especially physics related to it as we can associate with different laws of aerodynamics and motion. Paper airplanes have designs ranging from simple planes for kids to competitive and complex ones like moth, tumbler, spike and many more to mention. As kids, we never used to think about these principles and designs that are associated with every part of paper planes from its formation to its flight. But, as a science student, I have got an opportunity to explore the various aerodynamic principles and get a deeper knowledge about the physics of paper planes. History: The history of paper planes is not quite specific as there have been many people who have contributed their theories in this field. Da Vinci who was a famous Italian personality is often regarded as the inventor of paper airplanes while some have the belief that Chinese people are the real makers of this art as they were the ones who invented paper and kites. The modern paper planes saw their creation in the year 1909 while its acceptance was seen in after two decades in the year 1930 by John Northrop. Actually, Northrop tried these designs in order to test the real principles of flying aircrafts. From the early centuries till the current years, there have been many changes and corrections made in the structure of paper planes such as in their shape, style, fashion and lift. Thus, the paper airplanes have seen a lot of modifications in their shape and principles over these years and this credit goes to each and every person who has contributed to it though the history is not quite fa mous or known. Aerodynamics and Paper Airplanes: Aerodynamics is referred to as the branch of mechanics that deals with the motion of air and other gases and with the effects of such motion on bodies in the medium. Aero planes and helicopters follow the principles and theorems of this study of science and this is the case in the working of the paper plane models. The various principles that are used in this study and more specifically in the working of paper planes are drag, lift, flight, thrust, weight and velocity. But I will be concentrating more on the flight of these paper planes in regard with my topic. Lift, thrust, weight (gravity) and drag are the four important factors in the working and the distance covered by paper airplanes. Thrust- Thrust is the force on the horizontal left hand side of the paper airplane which decides the flight of the paper plane and this force comes from the strength of the pilot (in this case the person throwing or flying the paper plane). While taking flight, this altitude is converted into forward motion, which results in the proper flight of the airplane. Lift- Lift is another force on the vertical upper hand side of the paper airplane. Usually, the air below the wing of the airplane push the air on the upper side and the air above the wing push the air on the lower direction. At this point when the lower air pressure is much harder than the upper one, then the airplane is able to fly. And also the wings of the airplane are curved which allows the air to move over the top more quickly, thus resulting in lift or upward push. Drag- Drag is the force that is present in the horizontal right hand side of the paper airplane which allows or decides the maximum distance of any paper airplane. A plane is said to have a lot of drag when the plane pushes a lot of air, in which the paper airplane does not fly more distance. But when the drag is as low as possible the plane is able to cover more distance due to the low amount of air pressure in the horizontal direction. Drag can be compared to the friction present on the surface when any object is moving. Weight (gravity) Weight or gravity is the force that covers the vertical lower hand side of the paper airplane. The airplanes weight must also be less so that it can fight the attraction of gravitation and thus, the plane will be able to fly more distance in the air. The greater the weight, the more the attraction and the lesser the distance covered. Thus, these are the four crucial principles that have to be observed for any paper airplane to fly in the air. But, are only these principles responsible for the flight of the airplane? Are there any other factors that are also important in deciding the flight of a paper airplane? Do the physical quantities or the structure of the airplane play a major role in planning the flight or the distance covered? In order to research and find out whether there are any other principles related to the flying of airplanes that are made out of paper, I have performed an experiment that brings out the result whether the shape, weight and the structure play an important role in determining the flight of the paper airplane. Experiment: Aim: To determine the relation between the designs, type of paper used in the paper plane and the flight or the distance covered by the paper plane. Hypothesis: I had the initial idea that the paper planes that are lighter in weight cover more distance as they have the capacity to move in the air with the force or the pressure of the wind. And I also felt that the paper airplane of design Moth will cover the largest distance as I have experimented and used this design many times for its smooth kind of flying. I usually thought that the type of paper and design are both equally important for the flight of paper planes. Variables: Dependent variable- The distance that the paper planes covers is the dependent variable. Independent variable- The type of paper used and the designs of the paper planes are the independent variables. Controlled variable- The force with which the person throws the paper planes can be controlled and also the height and the direction in which the paper planes are thrown are controlled. Uncontrolled variable- the force of gravity and the drag in the air acting on the paper planes are uncontrolled. Also, external factors such as wind, dust particles cannot be controlled. Apparatus: 7 X Meter scale/ Ruler of 100 cm 1 X Chalk 5 X Paper planes of different designs made up of cardboard paper 5 X Paper planes of different designs made up of A-4 size normal paper 5 X Paper planes of different designs made up of hand-made paper 1 X Analytical balance Note: The paper planes used in the experiment must be of 5 different designs but these designs must be used throughout for every kind of paper used. Procedure: 1. Make the following paper airplanes with the following types of paper- Design of paper airplane Type of paper Type of paper Type of paper Pictures Arrow Cardboard Hand-made A-4 size normal paper Moth Cardboard Hand-made A-4 size normal paper Flying fish Cardboard Hand-made A-4 size normal paper Wide Cardboard Hand-made A-4 size normal paper Unknown Cardboard Hand-made A-4 size normal paper Note that the flaps or the wings of the paper planes must be folded in the upward direction. 2. Gather all the apparatus needed to perform the experiment and select a wide, open and a large area without any obstacles such as pillars or other objects in the area where the experiment is performed. 3. Firstly, mark the initial position with the help of a chalk. This position is the point or the line from where the paper plane needs to be thrown. Note that the person throwing the plane with the help of his hands must not exceed or go behind the line while throwing the plane. The initial position needs to be constant for all the paper planes. 4. Take all the paper planes of design Arrow of materials- cardboard, hand-made paper and A-4 size normal paper. Take each one of them and fly them from the height of the shoulder of the person who is throwing the paper plane. Measure the distance covered by the plane with the help of the chalk. Mark the point where the plane falls on the ground and then measure the distance from the initial position. 5. Similarly, repeat the experiment with the paper planes of other designs. Measure and record the distances of all the planes and tabulate the readings. 6. Also, measure the weight of all the paper planes on the analytical balance and record them. Risk Management: While making the paper planes, see to it that the shape is symmetrical and the folds that are made on the wings must be equal on both sides. Also, note that the person flies the paper plane with enough force. This is because the capacity of the paper plane to fight against the drag in the air increases if the initial velocity of the plane is high. Important note: Note that the readings of the distance covered by the paper planes must be taken at least 5 times to reduce the errors during the experiment. Also, whenever the paper planes are thrown, the tip of the paper plane must be made straight so that the plane flies smoothly on the basis of its shape and the type of paper used because the fold or the improper tip of the plane may be an obstruction for the plane to cover its normal distance.

Observations: From the observation table, we can almost indicate that the heaviest paper plane in every type of design covers the shortest distance while the lightest paper plane covers the highest distance. We see that the paper planes made out of cardboard paper are the heaviest in every design of paper used and the ones made out of A-4 size normal paper are the lightest. But in the table, there is an observation for the paper planes of design Paper Jet where the distance covered has drastically reduced for the cardboard paper when we compare planes with other types of papers used and also when we see the difference between other types of paper planes. Conclusion of the experiment: From the above observation, we can state that the design and weight of the paper plane and the type of paper used are important to determine the distance covered by the paper airplanes as we obtain different readings of distances covered by the paper airplanes of different designs. But, here the question arises as to why the weight affects the flight of the paper planes and another question is that what are the other relevant factors that affect the flight of the paper planes. Wings functioning theory: Wings are important features of any object or creature when it comes to flight and balance in air. Birds have wings with the help of which they are able to fly and for fast transportation and development of technology, these principles of the wings were used in the making of aero-planes. And these wings also play a crucial role in enabling the paper airplanes to fly through air. According to Bernoullis principle in relation to aerodynamics, whenever the speed of air is greater, the pressure that the air exerts on the surface is lower and vice versa. Thus, we can relate this principle to paper airplanes and state that when the paper airplane is in air, the air passes through both- the upper as well as the lower part of the wings. Also, the wings have an angle of attack as the wings are not straight while passing through the opposite air drag and they create an angle with the air. According to my experiment, when the wings pass through the air, the angle of attack is created with the air and thus, the wings move upwards. This activity makes the speed of air greater in the upward part of the wing and reduces the speed in the lower part. On applying the Bernoullis principle, the pressure on the upper part reduces, thus creating suction with the wing and pulling them upwards. While the pressure under the wings increases and this pushes the wings in the upward direction. This helps the paper airplane to remain aloft and stable in the air. There is another principle that helps the paper planes remain in air for a longer time which is Newtons third law of motion which states that every reaction has an equal and opposite reaction. During the flight of the plane, the wings face a considerable amount of air coming towards it and when this air applies force or creates pressure on the wings, the wings, in return, apply force and pressure on the air which helps them to remain stable in the air. Thus, Bernoullis principle and Newtons third law of motion are both appropriate reasons for the flight of paper airplanes in the air with the help of the wings. Also, this theory varies accordingly with the different types of designs used in the experiment because not all planes have the same structure of wings and thus, the amount of pressure and the amount of force applied on the wings is different. For example, the arrow, moth and delta wing have the same type of wings that are mentioned in the theory (that is they are tilted upwards). But designs such as paper jet and flying fish have quite different shapes of wings that are evident from the diagram of the airplanes shown in the experiment. Thus, for the paper jet, there are several folds and flaps in the wing itself and thus, the amount of pressure and the reaction force from the wings towards the air, are different at different parts of the wings. One part of the wing has several folds on one another while one part has a smooth surface. So, the wings air pressure at the smooth surface of the wing may be different than the pressure and force on the folded surface. Thus, there are possibilities of various kinds of movements such as ups and downs or loops or nosedives of the plane and thus, there is a difference in the distance covered by these planes. So, we can draw conclusions that the design of the wings or the planes is on e factor that is responsible for the distance covered by the paper planes. Weight theory: The observation table from the experiment proves that for these designs, the greater the weight of the planes is, the lesser distance is covered by them. Drag is the horizontal force that acts on the paper plane when it flies through the air. Thus, this force becomes an obstacle for the plane to cover more distance. In order to fight and resist this air pressure, we need to have a strong material of paper which has the capacity to resist the air drag. From the materials of paper used, cardboard paper is the heaviest and we can thus, say that it has the largest amount of power to resist air drag. But, at the same time, there is a force of gravity acting downwards towards the ground surface. And according to theory of gravity, the more the weight of the object is, the greater is the attraction. Hence, we can say that though the cardboard paper is the heaviest, it also has a greater force of attraction due to gravity. This mixture of gravitational force and the air drag makes the cardbo ard plane cover the least distance. Thus, the weight of the paper used is one reason which affects the distance covered by the paper planes. The above theories indicate that the wing functioning theory forms the basis for which the paper airplanes fly and the weight theory determines the distance covered by the paper airplanes in relation to its weight. Though the normal paper has the least weight, the wind and the force from the person throwing the plane enable the plane to move smoothly in the air. Thus, as there is least attraction of gravity for this plane, it is able to fly farther distances. Thus, the weight theory in regard with drag and gravity helps to determine the distance covered by the planes. Evaluation of the experiment: Improvement of errors: While throwing the paper airplane, the force applied on every paper airplane might not be the same which leads to the variations in the readings obtained. In order to improve this error, the person must decide a particular fixed amount of force or energy that he will apply to the plane. This action can help to reduce some amount of errors. The experiment is performed in an open area where there are now windows or sources of high air flow. Though high amount of air flow is avoided, there is a possibility of some kind of passage of wind which might affect the flight of the paper airplanes. For example, the amount of wind present may not be equal all time and thus, this may affect the flight of planes accordingly. Thus, the thrower must use enough force that can help the paper airplanes to overcome gravity and fight the air resistance. The distance covered by each paper plane was measured five times in order to reduce systematic errors. This step may also affect the flight of paper planes sometimes as the landing of the paper planes is very which may include crashes with the ground surface. Due to crashing, the sharp tip or the nose of the paper plane may get disturbed or blunt. And this change in the shape of the tip may lead to the variations in distances covered. To overcome this error, the thrower must be careful and always try to straighten up the tip of the paper airplanes. By doing so, the crashing of the planes can be avoided and the normal flight of the paper planes can be maintained. The folds and flaps of the paper airplanes have to be done with perfection so that there is no problem with the flight of the planes and the planes can cover their actual distances. For paper airplane readings of paper Jet, we notice that the distance covered by the normal and hand-made paper is quite different and higher than that covered by the cardboard paper plane. The reason for this is the design and the stiffness of the cardboard paper. The design of this paper plane is very complex and it includes several minor and major folds and flaps. Due to the tough material of cardboard paper, it is very difficult to follow all the steps of the design. Thus, the design of this plane is not perfect enough and the folds also do not remain stable. This is the reason why the paper plane covers very less distance as compared to other planes of the same design. In order to avoid these construction errors, the person may change the type of design used that fits according to the material of paper used or the folds must be done carefully and a much better plane of the same design can be constructed. The apparatus used in the experiment such as the analytical balance and the meter scale must work properly to avoid systematic errors and the weight and distances of the paper planes must be measured carefully. The calculations such as the average distance must be correct to avoid any random errors.

Enzymatic Functioning in Bromelain from Pineapple Juice

Enzymatic Functioning in Bromelain from Pineapple Juice William Nguyen Introduction An enzyme is a biological catalyst that accelerates specific chemical reactions. It converts substrates into specific products. Most enzymes are proteins and hence have a three-dimensional structure of folded polypeptide chains. Enzymes have an optimal temperature and pH range in which they function most effectively. If changes occur that remove the enzyme out of this range it may not function effectively. This principle forms the basis of this experimental design where the increasing temperature results in the denaturing of the enzymes found in bromelain and thus lowering its catalytic effectiveness. Bromelain is a protein extract present in the fruit, leaves and stems of pineapple plants (Ananas comosus). Although it is present in all parts of the pineapple plant, the stem is the most bromelain rich part that also makes it the most common commercial source of bromelain (Rowan, Buttle Barrett, 1990, p.869-875)1. The crude aqueous extract from the pineapple fruit is known as bromelain. It is in fact a mixture of different thiolendopeptidases and other components like phosphatases, glucosidases, peroxidases, cellulases, glycoproteins, carbohydrates and protease inhibitors (Maurer, 2001, p.1234-1245)2. It is also known that the enzymes in the bromelain extract begin to denature when heated over 80 °C (Jutamongkon Charoerein, 2010, p943-948)3. Since bromelain is essentially a mixture composed of many different enzymes, its substrate spectrum is very broad. It extends from synthetic low molecular amides and dipeptides up to high molecular substrates such as fibrin, gelatin, casein and bradykinin (Cooreman, 1978, p.107-121)4. Pineapples are an excellent source of the trace element manganese which acts as an essential cofactor for many of the enzymes found in bromelain. In addition, thiamine also acts as a cofactor in enzymatic reactions central to energy production in bromelain (Joy, 2010, p.67 0-686)5. Historically, bromelain has been extracted and utilised for medicinal purposes by the natives of South and Central America. In modern society, bromelain has been proven to be effective at tenderising meat and as such, is sold commercially as powdered meat tenderisers. It has also earned universal acceptability as a phytotherapeutical drug because of its history of safe use and no side effects. In 1972, conclusive evidence that bromelain prevents aggregation of blood platelets was reported by Heinicke et al (1972, p.844-845)6. Bromelain also displays an anti-inflammatory and analgesic effect on soft tissue injuries especially in rheumatoid arthritis and osteoarthritis. It has also been found to dramatically reduce post-operative swelling and pain due to these properties (Leipner, Iten Saller, 2001, p.779-789)7. Additionally, bromelain applied topically as a cream in a lipid base has shown beneficial characteristics in the debridement of eschar from severe burns and in the acceleratio n of healing. It has been commercially approved in Europe and sold under the trade name NexoBrid (Hauck, Chang Klein, 1983, p.124-134)8. Aim and Hypothesis This experiment aims to qualitatively identify the enzyme functioning found in commercially sold canned pineapple juice using background information provided by previous experiments. The rate at which gelatin is degraded in this experiment by the bromelain provides an indication of the rate of enzyme activity. The fresh pineapple sample is known to be rich in bromelain and as such, will hypothetically result in a significant amount of gelatin degradation. Boiling the pineapple juice sample over 80 °C will result in the denaturing of enzymes and should display little to no degradation of the gelatin. The canned sample in question may not display any degradation as it has undergone processing that may have disturbed the natural functioning of the enzymes in bromelain.

Placing test tubes in a bucket of crushed ice may quicken the cooling process Place allocated cubes of gelatin into respective tubes and allow to sit for 20 minutes Separate juice from the gelatin cubes and rinse with distilled water Allow gelatin cubes to completely dry Weigh the gelatin cubes and record variances in results table Results Table 1. Degree of enzymatic functioning in various types of pineapple juice Table 1 depicts data taken from part A of the experiment. Three trials were run for each type of juice to ensure reliable results. It is apparent that there is a large change in the diameter of the fresh pineapple juice samples compared to the other types tested. Whilst canned pineapple juice displayed a lower degree of change, the boiled sample however seemingly gained gelatin. The control sample did not display any changes in the diameter of the pit. Figure 1. Step 1 of the proteolytic gelation phase (Part A) Figure 2. Step 3 of the proteolytic gelation phase (Part A) Recorded Observations Many air bubbles were formed during the pipetting of juices into the gelatin pits The diameter of the gelatin pits appeared to remain the same after a period of 120 minutes for canned, control and boiled pineapple juice Visible changes in hole size observed in fresh pineapple juice samples Table 2. Effect of temperature on enzymatic functioning in bromelain Table 2 depicts data taken from part B of the experiment. Like part A, three trials were made for each variable to ensure reliable data. As temperature applied to the juice increases, it is evident that the degree of weight loss of the gelatin decreased. However, test tube 2 displayed a result that deviated from this trend as the weight loss (%) dropped then rose again. The control sample displayed the highest amount of weight loss of the gelatin cube. The trend (not inclusive of the control) is represented in the figure below. Figure 3. Effect of temperature on enzymatic functioning in bromelain ­Ã‚ ­ Figure 4. Step 3 of proteolytic gelation phase (Part B) Figure 5. Step 4 of proteolytic gelation phase (Part B) Recorded Observations Fresh pineapple juice retained a cloudy, yellow colour with froth formation on the surface of the juice During the cooling period, the pineapple pulp separates from the liquid and forms two distinct layers Gelatin cubes that were dropped into the test tubes rise to the top of the solution with pulp sediments resting on the bottom of the test tube Discussion Part A It was supported by the results in Table 1 that fresh pineapple juice displayed a larger degree of enzymatic functioning compared to the other three sample types (boiled, canned and control). This is depicted through the change in the diameter of the gelatin pit. Enzymes in bromelain work to break down the gelatin and the larger the pit, the greater the functioning of those enzymes. The fresh pineapple juice sample showed an 18.18% change in the diameter of the gelatin pit. The canned pineapple juice had a lower degree of change (5.49%). This may have stemmed from the preparation and processing of the juice that may have altered the integrity of the bromelain in the juice. It may have been subject to heating to sterilise the juice that may have caused the denaturing of the enzymes responsible for the breakdown of gelatin. The boiled pineapple juice presented data that goes against the principle of bromelain breaking down gelatin. With a change in diameter of -1.18%, it has actually ‘gained’ gelatin after the proteolytic gelation phase. Since it is known that bromelain is responsible only for the degradation of gelatin, it is impossible for it to produce gelatin. Thus, this miscalculation may only have resulted from human error in marking and measuring the diameter. The marker used in this specific experiment produced rather thick lines relative to the small diameters that were measured. Use of a finer tipped marker may have minimised the chances of such inaccuracies to occur. The control sample involved a set of gelatin plates with no pineapple juice added. This was made to ensure that the pineapple juice was responsible for the degradation of the gelatin. If the control displayed a change in the diameter of the gelatin pits, then the experiment would be deemed invalid as more than one factor contributes to the degradation of gelatin besides bromelain. In accordance to the results, the control group displayed no changes to the gelatin pits. Part B Part B of the experiment explores the effect of temperature on the enzymatic functioning of bromelain. From the data recorded in Table 2, an increase in temperature applied to the juice corresponds to the decrease in the functioning of the enzymes as depicted through the amount of weight the gelatin cube lost. This trend is illustrated in Figure 1. Whilst there is an overall decrease in weight loss associated with increased temperature, there is an outlier at 45oC. Although this variable was repeated thrice, it still remained inconsistent relative to the data set. Such an error may have occurred with the apparatus provided on the day of the experiment where there were only three water baths provided (37oC, 50oC and 90oC). The experiment design took into account the equipment available that was provided in the laboratory manual that offered water baths at 35oC, 45oC, 50oC, 60oC and 90oC. Hence, maintaining the pineapple juice at 45oC and 60oC using the apparatus provided was the most probable cause of the error. In the case of the 45oC variable, it may have been heated too strongly that resulted in the denaturing of many more enzymes compared to at 50oC and 60oC. To improve upon this error, water baths with temperatures corresponding to those given in the laboratory manual should be provided to ensure accurate quantitative data. As mentioned previously in the introduction, it is known from past experiments that the enzymes in bromelain begin to denature very quickly at 80oC (Jutamongkon Charoerein, 2010, p943-948)3. This experiment confirms the statement as the 90oC variable experienced a steep decline in weight lost that indicates a large degree of enzyme denaturing. Naturally, most enzymes have a temperature range that it functions most effectively at. However, this graph only portrays temperatures > 35oC, not covering a large range of temperatures that is able to point out the optimum temperature. Again, this was not able to be accounted for in the experimental design due to the limited apparatus provided. From the trend line in Figure 1, a linear decrease is shown. However, a bell curve is usually representative of the optimum temperature where very low temperatures result in decreased enzyme functioning and decreased weight loss. As the temperature increases the enzyme reaches its optimum level of functioning and results in a large amount of gelatin degradation. With temperature reaching higher levels, the enzymes begin to denature and cease to function which brings the levels of weight loss down again. Relative to this experiment, the optimum temperature is ideally oC. In addition, the control displayed the greatest amount of weight loss com pared to all the variables that were tested (36.14%). The control was not applied any heat but rather subject to room temperature which is ~20oC. This reinforces the notion that the optimum temperature of the enzymes responsible for the breakdown of gelatin is oC. To validate this statement, the experiment should be repeated again but with a wider range of temperatures to account for the bell curve trend that should occur to identify the optimum temperature. Reflective Comments This experiment on bromelain was performed by three persons including myself. The first part of this assessment task was performed individually as per instructions. After we completed this task, we got together and planned the experimental design. Each person was assigned a role in this activity where I was tasked with completing the risk assessment and drawing scientific diagrams. The other two collaborators were responsible for completing the methodology and the list of materials and equipment. When we had completed our tasks, we discussed each part together to come to a mutual agreement. Many modifications were made to all parts that were essential to keeping our experimental design valid. Designing this experimental protocol with my classmates was a pleasant experience as each one of us were committed and contributed to the project. During this part of the project, no significant difficulties were faced as we all worked through our tasks smoothly. To me, teamwork was already a no tion that I valued strongly, however this activity of getting together and completing such a large amount of work in so little time has definitely set that notion in stone. The approach to allocating tasks to different members was also done on the day of the experiment. An action plan was formulated with all the roles and times of the tasks that have been allocated and given to each member of the group. A great reason for doing this is so that we can minimise human error in repetitive tasks. For example, I had a role in heating the juices in the given hot water baths. If two of us were to heat it, one may have a different way of regulating the temperatures 45oC and 60oC (the temperatures not given) than the other member. Hence, we assigned such roles to be consistent with the method. It also maximises productivity so that all of us are working rather than one person work with the other looking on to see if they can help. The specific tasks that I have been allocated on this day was majority of Part B of the experiment. I was tasked with cutting the gelatin cubes, weighing and recording their weights, pipetting of juices into test tubes and heating the juices. After gelatin cubes have been dropped in and timed by another member, I removed, washed and dried the gelatin for the weighing process. In between my tasks where I had time I lent my assistance to my team members. At the end of the experiment we packed up the equipment and cleaned the lab bench so that we can sit down and discuss our results. The only minor problem experienced in this teamwork was the action plan. Some of the times allocated to specific tasks were under or overestimated. Although this is not necessarily a problem as we were provided three hours to conduct our experiment, it resulted in the clumping up of tasks where one member waited for another to finish their task to continue his/her own. Overall, I am very happy and satisfied with the outcomes of our team project (possibly the best team project I have ever had!). With minimal difficulties and great results, I would definitely proceed to approach teamwork like this in future projects. However, this method of teamwork is only suitable if all team members are committed to their roles. If one does not pull their weight and not complete their allocated roles, the group could fall apart. Hence, it would be best for me to find myself a group of dedicated individuals in future projects. References Rowan AD, Buttle DJ Barrett AJ, 1990.

Measurement, Irony and the Grotesque in Gullivers Travels :: Gullivers Travels Essays

Measurement, Irony and the Grotesque in Gulliver's Travels  Ã‚  Ã‚  Ã‚   Postmodernity is obsessed with the Eighteenth Century. As an example of how our nostalgia for that period manifests itself, Hans Kellner has pointed out that a genre of novels and films set in Eighteenth century has exploded in popularity: Lempriere's Dictionary, Perfume, "The Madness of King George III." We could also point to the ongoing revision of scholarship on the period, of which GEMCS itself is an example. In considering what generates this contemporary fascination I have given some thought to the aesthetic and political issues surrounding the beginnings, and perhaps also the end, of the bourgeois social sphere. A conviction, argued most aggressively by Jean Baudrillard, is beginning to take hold, in and out of the academy, that this sphere, after an almost totalizing expansion, is now in decline. The panic over the loss of the social, whether supportable or not, offers a possible explanation for the contemporary nostalgia for the period in which Swift wrote Gulliver's Travels. In this age of dissolution, what do we see when we look back at the age of our creation? One thing we observe is the development of a peculiar kind of irony which we can't help but distinguish from our experience of this trope in the age of its dominance. The satirical effect of the irony in Gulliver's Travels read by the Postmodern will be precisely what it was not at the time of its production. The historical distance between Eighteenth Century and Contemporary readers can be understood by way of Hayden White's use of the master tropes in "Foucault Decoded." White assigns one of the master tropes to each of the four archeological periods described by Foucault in The Order of Things. In White's system, Foucault's Renaissance was metaphorical, locating truth in similarity. Swift wrote in what Foucault considered the Classical Period, which, for White, had metonymy as its overriding mode of reason, because a new transparency of representation made it possible to organize knowledge by a standard and represent it symbolically on a table. The Modern period was characterized by synecdoche, in that the subject of knowledge, Man, was now included in the study of the world, in a part-whole relationship. Finally, the Contemporary or Postmodern mode is ironic, characterized by a questioning of the foundations of knowledge and a Dionysian disappearance of the subject of that knowledge.

Nancy J. Chodorow :: Biography

Personal Background Chodorow is often appointed as a leading theorist in feminist thought, especially in the field of psychoanalysis and feminist psychology. Her essays are included in many books concerning gender roles and construction as well as psychoanalysis. Her evaluations of the ways in which the psychological dynamics of the gender system is systematically generated and subject to historical change and development are acknowledged as significant contributions to feminist theory. Chodorow is now at the University of California at Berkeley, and she continues her Education and Training She graduated from Radcliffe College in 1966, she earned her PhD in sociology from Brandeis University and received her psychoanalytic training at the San Francisco Psychoanalytic Institute. She then received her PhD from Brandeis University in 1975. Major Contributions Chodorow begins her experiences with challenging psychoanalyst none other than Sigmund Frued. His ambition for psychoanalysis led him to his first methods and theories. These methods and theories are as followed; Oedipus complex, dream analysis and his understanding of sexuality and psychopathology. Nancy was inspired by the psychology of women contributions of the 1920’s and 1930’s. Frued’s Oedipus pivots an entire legacy of Nancy’s curiosity of mother-daughter psychology, and which led Frued (1931) to redefine the psychology of feminity. As Chodorow was influenced by the influencing psychoanalysis in the 1930’s, she realized that psychological anthropology (her own subspecialty) had explored the psychology of gender culture. Chodorow’s first women’s conference in 1969 is what propelled her and other women into awareness. â€Å"Being and Doing† was Chodorow’s first published book which contained a cross-cultural examination of the socialization of Males and Females (1972). Its main focus was that sexism is political, economic, familial institutions in terms of men’s behavior toward women. Chodorow explains that â€Å"Being and Doing† located the men’s origin of male dominance in men’s dread of women and fear of their own external feminity. Surprisingly, Chodorow found that male and female bisexual identifications were asymmetrical; the man’s being more threatening. (Chodorow, 2004). The book concluded that women’s identity was based on â€Å"being† and men’s masculine identity was based on â€Å"doing.† â€Å"Being and Doing† was published over 30 years ago and inadvertently anticipated many of themes that are now found in psychoanalytic rethinking of feminity. At this point in time Chodorow insists to take an intuitive and natural mode; beginning with a single, self-evident, taken-for granted but previously unnoticed or unstudied feature of psychic or culture world and expand the consequences of the fact from within the clinical moment (Chodorow, 2004).

Phil History

Many of us didn't know who are we and where we came from. From the quote â€Å"Nothing of me is original. I am the combined effort of everyone I've ever known†, it says that we, Filipinos don't have any original identity, our identity, like the political, social, economical, and cultural that we have today, came up from the colonization of the other country, like Spain, America, and Japan. Before the colonization of Spain, America, and Japan, Philippines said to have a vast culture In political, economical, social and cultural.In 7,107 Islands In the Philippines there are different people living with different political, economical, social and cultural approach. In pre-colonization, the system of government decentralized, meaning there is no center government to govern the other small government. The leader of the barbarian is a Data, Confederacy is a Rah, and Sultanate is a sultan. Their Judicial system Is oral, which means, whatever the law imposed by the leader It will be s poken through a messenger. They formed alliances through the process of â€Å"Sandburg†.Some lived near bodies of water, and some lived In the mountains or rest. The lifestyle of the people living near the bodies of water are fishing, boat building, pottery, farming, and so many more, while the people living in the mountains are swished, farming, hunting, gathering, etc. People living before the colonization, have a social strata, first is the imaging and data class, a ruling and warrior class. Second Is the maharaja, a wealthy class. Third Is the Tamaki or freeman, a commoner. Last Is the Labial or Roller, debt peons. People In the pre colonization have a system of writing called Babylon.They also have religion, called minims, they worship anoint/Anita, data and their priest/sees is called Babylon. The Muslims saw Misguidance and Sulk first before the Spaniards came to the Philippines and introduce their religion called Islam, where their God is Allah and prophet is Mohammed All. When the Spanish came to Philippines, their only purpose Is the g's: God, Gold and Glory. They colonize us in two ways, one is with religion and the other Is with the use of sword. Religion came to victorious. The Spaniards gave us new way to live our life; they also introduce us to their religion, which is Christianity.We, Filipinos at home set up altars in the Hispanic tradition, adorned with Catholic images, flowers and candles. During fiestas, most communities organize church services and religious processions in honor of a patron saint. Also, we inherit the holiday of the Spaniards, for January 1 – New years day, March or April – Seaman Santa also called Holy week, October 31 – November 2 – All saints day and all souls day, December 24 – Niche Buena also known as Christmas Eve, and December 25 – Christmas. They created two governments, one is the central government and the other is the local government.The central government is he aded by Governor-General, who is the commander-in-chief, head of an army and navy, he also have veto power, meaning if he seems the law is not good enough, he can nullify or cancel the law. He Is the Vice-Real Patron, and lastly, he Is the president provinces and the leader is called Lacked Mayor, Corrections, which are unified provinces, the leader is Corridors, Pueblo-towns, the leader is Gubernatorial, Cicada, the leader is Mountaintop and Barbarian, the leader is Caber. In the course of Spanish colonization in the Philippines, the friars instructed opulent Baroque-style church edifices.These structures are still found today everywhere across the country and they symbolize the cultural influence of Spain in Filipino life. The opulence of these edifices was clearly visible in the ornate facades, paintings, and sculpture, as well as in the behavioral patterns of the people and in the intricate rituals associated with Roman Catholic churches. While it is true that the Spaniards expl oited labor in the construction of the imposing Baroque-style sanctuaries for Roman Catholic worship, it is also true that these same edifices came the means by which Filipino artistic talents and inclinations were expressed.The carpenters, masons, craftsmen, and artisans were mainly Filipinos. In this way, the Roman Catholic Church and religion influenced Filipino architectural and building style, even as the rituals and festivities of the Church influenced Filipino dances, songs, paintings, and literary writings. Through these influences, the Church afforded the Filipinos abundant opportunities for both solemn rites and Joyous festivities and celebrations known as â€Å"fiestas. The services inside the Catholic hurries often spilled out into the thoroughfare in the form of colorful and pageant- filled religious processions in which the rich and the poor participated. Dining, drinking, and merrymaking often followed or accompanied such religious activities. During these feasts, Sp anish culinary specialties like â€Å"paella† which means a dish consisting of a mixture of rice, chicken and shellfish, â€Å"razor valerian† which means glutinous rice and chicken cooked in coconut milk, and â€Å"lingua† meaning sautà ©ed ox- tongue usually with mushroom sauce became part of the local table fare.The rites ND feasts served to provide relief from the drudgery of humdrum village existence, to release pent-up social and economic frustrations, or to foster community spirit and unity. With the help of the Americans, Philippines got its independence after the sacrifices they undergo under the Spaniards. After the independence, Americans redistribute the enormous land properties that were given during the Spanish period to the Catholic Church. Even though they redistribute the land, the small farmers didn't get any land because they can't prove that they are the owner of that land and they can't pay the asked price.The lands became the property of l arge landowners. American General Douglas Mac Arthur landed in Elite, one of the biggest islands in Central Island of the Philippines with 700 vessel and 174 000 army and navy. Since the American led us, the government was divided into three branches: Judiciary, system of courts that interprets and applies the law in the name of state. It also provides a mechanism for the resolution of disputes among people. Legislative, the one who make the law or pertaining to the enactment of law. Last is, Executive, the one who enforces the law or have the power to put plans, actions or laws into effect.There are also schools that were built during their time, like the agricultural schools; Philippine Normal University and University of the Philippines. Their medium of instruction was English and the teachers are called Atomies. Also, there were public schools that were open up for the education of the Filipinos. Also, during the introduced to us by the Americans and approximately three hundred thousand Filipinos become protestant. In the economical part, Americans built roads, streets, bridges, and new infrastructures that made movement of products and services more efficient.It also improved the Philippines economy by the development of new industries, increase in agricultural production. In the social part, Filipinos learned to play games, watch movies, new kinds of music introduced to us by Americans, using respectful greetings like â€Å"Magenta magma PDP' were replaced by merely saying â€Å"Good morning†, â€Å"Paganism' was replaced by kissing the cheeks of parents and elders as a sign of respect. We lost our sense of â€Å"banish. † Women wear dresses, high- heeled shoes, and a handbag, while men, Suits, polo shirts, ties and Jeans. The Japanese started when they started attacking the Pearl Habit.It is also in the Japanese time, when the Filipinos do the death march from Bataan to San Fernando Pangaea where many of Filipino died. In their occupatio n, the Japanese introduced to us duck farming, fish breeding, and other influences like removing slippers before entering the house, bonsai planting, and manufacturing farm tools and war weapons. They also taught us origami, their martial art, Judo, and tanning of deer skin. Since the Japanese where here for Just a short period of time, they didn't leave much of their culture but they change the way things are done in the Philippines. Just like strict curfews was enforced.Even though our country has an identity of our own before the coming of the colonizers, like Filipinos know how to survive and have their own ways to live, they can create things by the use of what they see in their surroundings, but we had been greatly influenced by the country that colonized us. I think that the three countries that colonized us changed our political, economical, cultural and social system of our country. I think our identity today, as Filipinos are mixed from the Spanish, Americans and Japanese influence to us. Our lifestyles that we have now came from different influences of other country to us.Today, some of the Filipinos still do â€Å"banish† in some of the provinces in the Philippines, There are many Spanish influences on Filipino culture. Thousands of Spanish words are load in most Filipino languages. We, Filipinos sometime speak Spanish, when we have simple conversation, like mesa, silly, and many other Spanish words, all over the Philippines. The traditions of the Spanish, their holidays, their religion, and even their government are also the influences of the Spaniards as they colonized our country. The influence of the Spanish, like â€Å"paganism as inkstands† still lives in us or inAmerican influence, â€Å"packaging as pissing† some of the Filipino do this as a respect to the elderly or to their parents. The way of how we dress is also influenced by Spanish and America. We wear coat and tie for going to work, Barron and flapping dress for attending marriage or baptism, and gown or dresses for attending formal parties. We also adopt their government which is the local and central government. We also adopt the system of government of America given to us, the legislative, the Judiciary and the executive. With the help of the American, the agriculture of our country has en improved.

Further Reflections on the Public Sphere Essay

The text edition is about relationship of res publica and courteous auberge, the origins of and prospects for democracy and the impact of the media. A pleasing of rethinking of Habermas first major work, The Structural geological fault of the Public vault of heaven published in 1962 and translated into English in 1989 which describes the arrestment of a mercenary humanity cranial orbit in the eighteenth and early nineteenth centuries as well as its subsequent decline. Habermas admits, his speculation has changed since then and he reminds readers of these changes.1.The Genesis and concept of the Bourgeois Public SphereThe habitual field of battle (ffentlichkeit ) is an area in fond life (standing in-between individual(a) individuals and presidential term authorities) where individuals sack up meet to freely turn man motley matters, exchanged views and knowledge and done that discussion influence political save. A vibrant popular discipline of influence of influence serves as a positive counterweight to regime authorities (are out of the state control) and happens physically in face-to-face meetings in coffee bean houses and humans squares as well as in books, theatre etc.The man sphere issued first in Britain and in the 18th century in Continental Europe. The newspapers, reading rooms, freemasonry lodges and coffeehouses marked the gradual egress of the familiar sphere.Habermas mentions Geoff Eleys objection to his foregoing depiction of bourgeois existence sphere is an idealized conception. Habermas admits now the coexistence of several competing universe spheres and groups, that were excluded form the dominant globe sphere the so called plebian state-supported sphere (like Jacobins, technical analyst movement). Habermas influenced here by Guenter Lottes and greatly by Mikhail Bakhtin, who opened his eyes to the culture of frequent people as a godforsaken counter project to the dominant public sphere. Habermas now vi ews quite differently the projection of women as well.Habermas asks himself were women excluded from the dominant public sphere in the same fashion as the habitual people? He answers himself with no the exclusion of women had structuring significance, as it was happening non exclusively in the public sphere, hardly also in the private sphere.At the end of this chapter Habermas summons up his bourgeois public sphere was formerly conceived to a fault rigidly. In fact, from the very beginning a dominant bourgeois public collided with a plebeian (and female) one. As a result, the melody between the early public sphere and the nows decayed public sphere is no longer so deep.2.The Structural Transformations of the Public Sphere cardinal RevisionsThis chapter traces the transition from the liberal bourgeois public sphere to the current voltaic pile ordination of the companionable welfare state. Starting in the 1830s, a transformation of state and parsimoniousness took shape . Clear borderlines between public and private and between state and rescript became blurred, as a result of interventionist state policies. The increase re-integration and entwining (msen se) of state and society resulted in the modern social welfare state.In the subchapter 1 Habermas deals with the impact of these developments on the private sphere. civilian society was formerly totally private, there was no difference between social and family life. This changes with the emancipation of lower strata (workers), a polarization of social and intimate sphere arrives. Habermas describes a dispute among cardinal schools in the 1950s, that of bourgeois Carl Schmitt school (and Ernst Fortshoff) and Marxist Wolfgang Abendroth, that influenced his considerations at that time, though like a shot he distances himself from his approach.In the subchapter 2 Habermas is concerned with changes in the structure of the public sphere and in the composition and demeanor of the public. The inf rastructure of the public sphere has changed collectible to changes in media, advertising and literature that has plump oriented to new social groups (workers) as well as due to the snap off of the liberal associational life. Since the 1960s, when Habermas book was published, the opportunities for portal to public communication became even more(prenominal) difficult.The public sphere is today reign by the cud media., which turned the lively public into a passive consumer public and caused a decay of the public sphere. Nevertheless, Habermas says his elder concept of a unilinear development from a culture-debating to a culture-consuming public was too simple and pessimistic. Habermas explains this by general situation of media make studies at that time he relied on Lazarsfelds behavioristic research and had no information brought later by Stuart star sign (audience does non simply passively absorb a text).Subchapter 3 deals with the legitimation crop of mass democracy and two diverging concepts of public judicial decision an informal, nonpublic opinion and a formal quasi public opinion (made by mass media), that ofttimes collide.3.A Modified Theoretical FrameworkThe mass democracies constituted as social-welfare states can rest the principles of the liberal constitutional state only as long as they get a line to live up to the mandate of a public sphere that fulfills political functions. It is indispensable to demonstrate how it may be assertable for the public to set in effort a censorious process of public communication. Habermas asks himself, weather there can emerge a general interest of the kind to which a public opinion can refer to as a criterion. Habermas could non resolve this problem before. Today he is able to reformulate the question and form an answer.The ideals of bourgeois humanism function today as a utopian vision, which makes it tantalising to idealize the bourgeois public sphere too much. thus Habermas suggests t he foundations of the critical theory of society be laid at a deeper level and beyond the scepter of modern societies.In the 1960s Habermas believed that society and its self-organization was a totality (celek) arrogant all spheres of its life. This notion has become improbable today e.g. economic schema of a society is regulated independently through markets. Later emerged his dual concept of society the internal subjective viewpoint of the lifeworld and the foreign viewpoint of the system. The aim today as he sees it is to erect a dam against an encroachment (naruovn) of system on the lifeworld, to reach a remnant between the social-integrative power of solidarity (lifeworld) and money + administrative power (system).Communicative action serves to radiate and renew cultural knowledge, in a process of achieving mutual understandings. It then coordinates action towards social integration and solidarity. This can be met in traditional societies. Less often in posttraditiona l societies with their confused pluralism of various competing forms of life. Habermas criticizes Rousseau for his utopian concept of the general will of citizens in a democracy as a consensus of hearts rather than of arguments. Habermas sees the solution in the process of public communication itself.Therefore democracy is rooted in public reasoning among equal citizens. State institutions are true(a) only when they establish a framework for free public figuring (debata). Such a rational debate is the most suitable procedure for adjudicate moral-practical questions as well. The question remains how such a debate can be institutionalized so that it bridges the disruption between self-interest and orientation to the common good (between the roles of client (private) and citizen (public)). Such a debate moldiness meet two preconditions presumption of impartiality and ability to hap initial preferences. These conditions must be guaranteed by legal procedures (institutionalized) a nd they themselves shall be subject to the law. new institutions should be considered, that would counteract the trend toward the switching of citizens into clients (i.e. toward alienation of citizens from the political process).Democracy shall be not restricted only to state institutional arrangements. They shall interplay with autonomous networks and groups with a unrehearsed flow of communication, that are the one stay embodiment of the altogether dispersed reign of the people. Democratic public life cannot develop where matters of public importance are not discussed by citizens. However, discourses do not reign the responsibility for practically consequential decisions must be based in an institution.4.Civil indian lodge or Political Public SpherePolitical public sphere is characterized by two processes 1) the communicative generation of legitimate power 2) manipulative power of mass media. A public sphere sine qua non more than just state institutions it requires a popu lace accustomed to freedom and the supportive spirit of differentially organized lifeworlds with their critical reflection and spontaneous communication uncoerced unions outside the realm of the state and the providence (church, independent media, leisure clubs etc.) They are not part of the system, but they have a political impact, as was seen in totalistic regimes, e.g. in the communist states of Eastern and exchange Europe. In Western-type democracies these associations are established at bottom the institutional framework of the state. Habermas asks himself the question, to what extent such a public sphere reign by mass media can set down about any changes. This can be answered only by means of existential research.He concludes with reference to a watch No Sense of Place by J.Meyrowitz, who claims that electronic media dissolve social structures and boundaries (like in primitive societies). Habermas disagrees new roles and constraints arise in the process of using elec tronic communication.
