The beliefs and practices associated with Holy Communion Essay Example

The beliefs and practices associated with Holy Communion Paper Holy Communion is a practice performed by Christians, for a number of reasons relating to belief and worship. While the ways in which Holy Communion is celebrated differ among the churches, communion prayers tend to revolve around the story of the last supper and the act of Christ giving his disciples bread and wine, and declaring it as his body and blood. This is the story of the last supper, the last meal Jesus shared with his disciples on the night of the Passover before he was betrayed by Judas, arrested and then executed. During the meal Jesus and his disciples were at the supper table and he broke some bread, gave it to his disciples and said, This is my body which is given for you. Every time you eat bread, think of me. Jesus took a cup of wine and gave it to the disciples and told them to drink from the cup and said, This wine is my blood that will be shed to remove the sins of all who come to believe in me and it is the start of a new agreement between God and mankind. The significance of this event, has been interpreted by the churches in different ways, which in turn has led to the variety of ways in which Communion is practiced among the churches.

While the majority of churches practice Holy Communion, there are a few churches that dont practice it at all, such as the Salvation Army and the Quakers. While there are some differences in the way that Communion is celebrated between the Orthodox and Roman Catholic churches (both high churches) the difference between the Roman Catholic church and Methodist church (low church) is far more substantial. There are two fundamental differences. The first and perhaps the most important difference is in the interpretation by each church of the way in which celebrating Holy Communion affects the individual taking part. This is known as the issue of belief associated with Holy Communion. This is explained in more detail in the paragraphs below. The second important difference, one that is easier to recognise, is in the way in which churches prepare for and perform Holy Communion. While some churches continue to adopt traditional methods to perform Holy Communion others adopt a far more informal approach. The high churches, such as the Roman Catholic and Orthodox, stick to very traditional methods and attach central importance to taking Holy Communion. By contrast low churches such as Baptist and Methodist, while they do celebrate Holy Communion, they do not regard it as being any where near as important as the higher churches, and tend to celebrate it in a much more relaxed and informal manner. The following are examples of how individual churches perform Holy Communion and the reasons they attach different levels of importance to it. Catholics refer to Communion as the Eucharist and practice it in a very traditional way. The first thing to note is that while some churches celebrate Communion on a weekly or more infrequent basis, Catholics can take Communion every day. It is not a requirement for Roman Catholics to go every morning but it is strongly encouraged by the church to attend Communion (Mass) as often as possible and at least once a week. This explains why Communion is so very important for Roman Catholics and is often described as the central form of catholic worship. The only person allowed to administer Communion is a validly ordained Priest acting in the role of Christ. In other words, the Priest represents Christ and his body and his blood are represented by wafers made from wheat (called the host) and wine made from grapes. Catholics believe that the Holy Spirit is contained within the wafers and the wine and that in the act of receiving communion the congregation is taking in the Holy Spirit. It is therefore central to the Catholic faith, so much so that they believe that by taking communion they are taking in the strength of the Holy Spirit which will help them lead a life free of sin. The quotation from John 6:53 sums up the overall belief held by Roman Catholics In Communion, we are eating the True Body and Blood of Jesus Christ, without which you shall not have life in you. Their interpretation of the story of the bread and wine is very literal. Communion can only be taken by those who have been baptised into the Catholic faith and have taken their First Holy Communion. This usually happens around the age of 7 or 8. The traditional Catholic church service (mass) follows a set format (liturgy) and concludes with the taking of Communion. During Communion wafers are used instead of bread, fermented wine is used which is taken from a shared chalice. The priest holds up the wafer as he says, the body of Christ and hands it over to the person receiving communion at which point this person would say, Amen. Then the priest pours out the wine and says, The blood of Christ at which point the person receiving communion takes the chalice and says, Amen. Any leftover bread or wine is either eaten by the priest or kept as reserved sacrament for the infirm in the parish. This routine tends to differ only very slightly between the high churches. The low churches have a much less traditional way of celebrating communion, which tends to link to the fact that they believe the bread and wine only represent the body and blood of Christ in a metaphorical sense, but that by performing communion they are only reminding themselves of Jesus, and believe that his spirit is no more present than usual. For example, Baptist and Methodist churches also hold Communion, which they call the Lords Supper, but they use less traditional methods of practice and hold it in lower regards. The members of these lower churches do not actually accept the belief that Jesus spirit is present within the bread and wine, and so do not take the service as seriously, but they do perform the Lords Supper with the intention of remembering Jesus. The argument used by these lower church members to support their views is that Jesus meant the bread and wine was his body and blood in a metaphorical sense, and the phrase they value most during the Last Supper is when Jesus said, Do this in memory of me. A typical Baptist communion takes place monthly and the only qualification necessary to receive The Lords Supper is a membership with the church. Examples of how the Baptist version of communion differs from the higher church versions of communion are the fact that a table is used instead of an altar, there is no set form (Liturgy), there is no main service and there is no need for an ordained minister. Bread is used but instead of wine they either use unfermented wine or fruit juice and instead of drinking this from a shared chalice they have individual glasses. The people receiving the Lords Supper remain in their seats while receiving it and they all drink at the same time. Any bread left over is given away and any unfermented wine or fruit juice is returned to the bottle. It is clear to see that from the differences in practice, the lower churches believe Communion to be less important. For example, the fact that they return the wine or juice to the bottle shows that they do not believe it to be the blood of Christ, as otherwise they would treat it with higher respect. Methodists also receive communion in a less traditional way but they do have a main service while taking Communion and an ordained minister is necessary. They also would have to go up to the table to receive The Lords Supper and do not all drink at the same time. Other churches, such as the Church of England would celebrate Communion, or as it is known in the Church of England, Eucharist, in an almost identical way to the Roman Catholic church, the only differences being that they use both an altar and a table and they may also use bread instead of wafers. This almost identically shared practice displays almost identical beliefs shared by both members of the churches regarding communion. Christians that do not have a specific building in which to worship and attend communion often practice their religion at home alone or with others in what is called a house church. The practices will remain roughly the same from house to house, due to a lack of an altar or ordained minister, but the beliefs will vary depending on the individual receiving Communion.

Elements of the Strategic Management Process

Elements of the Strategic Management Process Business organizations thrive on long term and short term strategic decisions which drive them to success. These cross functional managerial decisions are fundamental in determining a business organization’s strategic position and its ability to sustain itself in a competitively and dynamically changing environment.Advertising We will write a custom essay sample on Elements of the Strategic Management Process specifically for you for only $16.05 $11/page Learn More Therefore to formulate good business policies, a business manager needs to continuously assess the operational business environment to make strategic decisions in line with an organization’s planning and innovation processes. An Intelligent business executive continuously monitors the political environment in which a business organization operates to ensure potential risks associated with political uncertainties do not get into the way of an organization’s business operations. Ireland, Duane, and Hitt (23) assert that a business organization is likely to suffer heavy losses if a strategic decision made by its executives embodied in its strategic vision does not consider potentially dangerous situations like military invasions. Inconsistent industry regulations and requirements, time allotted for work for every employee or work week, intellectual property laws, legal requirements in making contracts, relationships with trade unions, and specific anti-trust laws can adversely affect a business’s sustainability and operations if such factors are not considered in making long term or short term strategic decisions I(reland, Duane Hitt, 56) Business organizations only thrive in economically stable environments which inspire the confidence for sustained profits. Such environments provide competently skilled manpower, stable currencies of host nations, sustained economic growth, sustained income, and stable inflation rates. When making long term strateg ic management decisions, managers need to identify and evaluate the characteristic type of the economic environment and controls in an economy when strategizing for the future. These ensure the safety and sustainability of an organization’s financial resources. Understanding the social environment enables managers to make strategic decisions in relation to the demographics of an organization’s market environment. Demographic factors determine how an organization designs its products to address the specific needs of a population.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Akbar (1) argues that this helps managers to make strategic plans for sustaining a business organization in today’s fiercely competitive environment. Long term strategies are fundamentally influenced by a market’s social class structures, innovation, cultural norms and values, and educational levels. Different social classes perceive different products differently. They also have different consumer behaviors. Products should be tailored to meet the needs and wants of different classes. Innovative managers make long term strategic decisions tailored to meet customer needs from different social classes while bearing in mind the need to make sustainable business decisions. That sustains a business organization in achieving its short term and long term goals and objectives in line with its strategic vision. According to Akbar (1), companies continuously innovate at every stage of their growth and evolution. When managers make long term decisions, new technological environment remain key factors in influencing such decisions. New technologies place organization at a strategically competitive position against its rivals in terms of innovation and efficient and effective utilization of resources. Effective managers find themselves compelled to consider the effect of these new technologies on cost framework. Costs are likely to go down drastically when new technologies which come with a range of benefits are considered in decision making. Organizations which remain static and do not adapt to new technologies find themselves loosing out to their rivals ho adapt to new technologies. Akbar, Michael.

Management and leadership development Essay Example | Topics and Well Written Essays - 2000 words - 1

Management and leadership development - Essay Example Emphasis is given on the operationalisation of management and leadership development into practice. Appropriate literature is used for highlighting the key issues of the study’s subject. At the next level, the article of the Emerald Group Publishing Limited (2010) ‘Changing Face of Leadership’ is used in order to show the key aspects of the operationalisation of leadership management in practice, as derived through the approach used by the article’s authors. It is concluded that the operationalization of leadership management into practice can be a challenging task – not just because of the requirements of these plans but also because of their implications for the leaders and the organizations. Leadership development is a multi-dimensional plan. When such plan is to be developed within a particular organization, it is important that its implications and its expected benefits are estimated and evaluated. The requirements of the specific plan need also to be taken into account, aiming to reduce the chances of failures when initiating such project. The leadership development affects the organizational life, in terms of the organization’s daily operational activities but also in terms of the context of its strategic choices. These issues are highlighted in the literature. Different approaches have been used for explaining the aspects of operationalisation of leadership development in organizations of different structural and operational characteristics. In accordance with Ryan (2007) the leadership development can lead to the establishment of inequality within the organization; it is explained that leadership is not equally developed across the departments of a particular organization. In certain teams of the organization, leadership plays a key role; in those teams, a significant amount of resources is likely to be invested on leadership development; in other organizational teams – referring to groups of individuals in different

Teaching High School Badminton Essay Example | Topics and Well Written Essays - 2500 words

Teaching High School Badminton - Essay Example The objective of the researcher is to create a curriculum design for teaching badminton to a diverse high school population. The curriculum must also address students who went through special education. It is a modified form of instruction that caters to students with singular needs or disabilities such as learning differences, mental health problems and other physical and developmental disabilities. Since the majority of the students with disabilities that have returned to general education consists of: 1.) students that have health impairments such as asthma and other chronic health conditions with proper medical clearance and, 2.) students with learning disabilities such as speech and language impairments1, the curriculum would deal with such students in order to narrow the broad scope of students taking special education. Learning disabilities are neural conditions which affect many areas of perception such as: 1.) visual or auditory discrimination, the perception of differences in either sights or sounds, 2.) visual or auditory closure, the completion of missing parts of sights or sounds, 3.) visual or auditory figure-ground discrimination, the ability of a person to focus on an object and disregard the background, 4.) both short term and long term visual or auditory memory w... right order, 6.) auditory association and comprehension which relates what is heard to the meanings of words and sentences, 7.) spatial perception which allows a person to perceive his laterality and his position in space, 8.) temporal perception, the processing of time intervals in the range of milliseconds and, 9.) non-verbal learning, the processing of nonverbal cues in social interactions.Because badminton is a racket sport that requires a great deal of hand-eye coordination and at a certain pace, may require its players to have aerobic stamina, strength and speed, drills and conditioning exercises that would augment the learning process of students with learning disabilities and physical constraints should be added in the curriculum.There are many specialized terms associated with curriculum design, these terms are not defined the same way by many professionals in this field. According to David Armstrong, these are the basic design concepts that must be considered when one is de signing a curriculum: 1.) scope, 2.) sequence, 3.) articulation, 4.) continuity, and 5.) balance.2 Scope "refers to the extent and depth of content coverage."3 This is very significant in curriculum development because of its dependence on instructional time. Since the time given for a certain subject is fixed, expanding the coverage in one area would lead to the reduction of the coverage of another area. The scope can be molded by these considerations: 1.) legal constraints, 2.) content significance, 3.) content authenticity, 4.) motivational appeal, 5.) content complexity, and 6.) the instructor's background and support-material availability.4Legal constraints refer to the decisions that cannot be changed by the curriculum developers. These are usually mandated by

How important is it that education is immediately and obviously Essay - 1

How important is it that education is immediately and obviously relevant to the interests of the pupils and to life in society - Essay Example Another education act was passed in 1944; it administered the creation of the Ministry of education, which in turn established compulsory and free secondary school education. The essay discusses how education is important and its relevance to the pupils and the society in the United Kingdom. The types of schools clearly show how education is important in the United Kingdom. Most of the most famous schools in the United Kingdom are the private boarding schools, for instance, the Winchester School. The famous private schools were founded in the middle ages and parents need to pay a lot of fees for their children to study in such schools (Arthur 2010, p. 82). Although, the schools are considered for the influential and rich families; they also offer scholarships for the gifted but poor children. Private schools that take children between the age of 7 and 13 are referred to as kindergartens. On the other hand, those that take children between the age of 11 and 19 are referred to as public schools. Research shows that only 7 per cent of the United Kingdom attends the private schools (O’Hear&Sidwell 2009, p. 34). The General Certificate of Secondary Education (GCSE) is given at age 16. If the student qualifies, he or she proceeds to the Advanced level of education commonly referred to as the â€Å"A† levels. Some of the students can be advised to stay in school up to age 18 to prepare themselves for higher education. The United Kingdom has 90 universities which the students can enrol. They are divided into several categories. The common universities are the University of Cambridge and University of Oxford (Bubb 2009, p. 56). Apart from the universities, students can also enrol in advanced education. The advanced education mainly focuses on applied technology and sciences, and they are polytechnics (Wright 2010, p.78). The polytechnic focuses on people who may not have qualified to go to

Measuring Concentration of Natural Gas in Air

Measuring Concentration of Natural Gas in Air Valentin Haemmerli Measuring concentration of natural gas in air using a catalytic bead sensor and a Wheatstone bridge circuit Abstract. A vacuum system and a catalytic bead combustible gas sensor were used to calibrate and test an apparatus for measuring the concentration of natural gas in air. Total concentrations ranged between 0%-5% and total pressure from 0.5 bar to 1.5 bar. A Wheatstone bridge circuit was used to measure the output voltage of the sensors and relate this to concentration over the range of pressures. The linear relationship between reaction rate (given by initial rate of change of output voltage) and concentration was most strongly observed at pressures of 1 bar and above. The constant of proportionality for the equation (1) was found to be 8.7  ±0.4 10-4 Vs-1 per % methane for a total system pressure of 1 bar. The relationship broke down for pressures significantly below 1 bar, indicating that the sensors are not reliable in this range. Introduction Catalytic bead sensors, also known as pellistors [1], are used in a wide range of applications in industry to monitor levels of combustible gases. One such combustible gas is the mixture consisting mainly of methane referred to as natural gas. The catalytic bead sensors can be used to monitor the concentration of natural gas in production facilities, coal mines and industrial processes. This is important because if the concentration of natural gas in air exceeds 5% it becomes explosive [2]. It is especially important to monitor methane concentration because it is usually colourless and odourless [3], making it very difficult to detect without sensors. An apparatus to measure concentration of natural gas in air can be used to trigger an alarm when there is a concentration greater than the Lower Explosive Limit (LEL), given as a percentage. At this concentration the mixture of gas and air becomes explosive. The apparatus may need to be applied for different pressure environments, not only atmospheric pressure, for example in applications with chemical processes requiring lower or higher pressures. The apparatus has therefore been tested for a range of pressures from 0.5 -1.5 bar. Theory Sensors The sensors used are catalytic bead sensors. One sensor is made up of two elements, one sensitive and one non-sensitive. The sensors work by catalysing the oxidation reaction of combustible hydrocarbons in the sensitive element which consists of a platinum wire coated in a compound which facilitates the oxidation reaction and also contains the catalyst for this reaction. The non-sensitive element is identical in most regards, but crucially is missing the oxidizing chemical or has had it poisoned, depending on the specific sensor design used. Poisoning means that the catalyst has been reacted with another chemical to make it inert. The non-sensitive element does not react with combustible gases. The elements are supplied with 3V, and heated up to 400-500ËÅ ¡C to speed up the reaction. When the oxidation reaction of combustible gases occurs on the sensitive element, the heat of reaction increases the temperature of the element, which changes the resistance in the platinum wire. Th e non-sensitive element acts as a control for ambient temperature, meaning that in the absence of any combustible gas, the two elements will output exactly the same voltage. This is very useful as it means that change in temperature due to external factors is controlled and the difference in output between the sensitive and non-sensitive elements can be measured using a Wheatstone bridge circuit as described below. This design means that these sensors detect a multitude of different combustible gases and are therefore not useful for distinguishing between them, meaning they are nonspecific [4]. However, they are very useful for situations where monitoring combustibility is of importance, and they can be applied readily to the task of measuring concentration as they are accurate and have a fast response time. The sensors used are sensitive, with a measurement range of 0-100% of the LEL. This corresponds to 0-5% concentration of methane. One downside of these sensors is that they cannot operate in a vacuum as they rely on combustion, which usually requires at least 15% oxygen [4]. They are also at risk of poisoning since they rely on a coat of catalyst and the presence of certain chemicals can result in a reaction with this catalyst, meaning the sensitive element would no longer facilitate the oxidation reaction and the difference in output between the elements would always be zero. Wheatstone Bridge Circuit Jeong-Yeol Yoon states that â€Å"A Wheatstone bridge is an electrical circuit used to measure a very small change in resistance† [5]. A circuit as shown in Figure 1 can be used to measure the output from the sensors, where a small resistance change is expected as a result of the sensitive element heating up due to the presence and reaction of combustible gases. A voltage is supplied at the top and bottom of the diamond of resistors, and the voltage across the middle, between V1 and V2 is measured. The right leg of the bridge should have a large resistance compared to the other leg so that a small change can be detected. The variable resistor allows one to slightly vary the resistance on one leg and so balance the bridge before measurements, zeroing the output. Experimental Method The first step was to test how sensor output related to concentration for a total pressure of 1bar (atmospheric). Care was taken to ensure that all joints and seals of the vacuum system were tight and that all valves were firmly closed. The vacuum system used to prepare test mixtures is shown in Figure 2. P1 and P2, the pressure sensors shown in the figure, were used to measure concentration of natural gas and air. P1 had a range of 3 bar, with the zero set to atmospheric pressure (1bar), and vacuum (0bar) set to -1. This was not very precise, with an uncertainty of  ±0.1bar and was used to fill up the system with compressed air and the pressure shown by this corresponded to total pressure. P2 was a more precise pressure sensor, ranging from 0 to 50 mbar with uncertainty  ±0.5mbar. It was used to carefully add the correct proportion of natural gas to the vacuum, before topping up with compressed air. Using this vacuum system, concentrations ranging from 0-5% natural gas were prepared. Figure 2 also shows the position of the pellistor sensor’s two elements and the connection to the Wheatstone bridge circuit. The output of this circuit was connected to a ÃŽ ¼V meter which was connected to a computer for dat a logging. This had a range of -30.00 to 30.00mV with uncertainty  ±0.01mV. Data logging was carried out for 5 minutes and 30s for concentrations of 1%, 2%, 3%, 4% and 5% at a total pressure of 1 bar. Errors were reduced by zeroing the Wheatstone bridge output using the variable resistor between measurements. This was done to reduce the effect of a natural drift in the output due to very slightly varying conditions in the lab such as temperature and the resistance in the circuit, as well as mechanical vibrations. The bridge circuit supply voltage was kept at a constant 3.00V. Care was taken to leave little time between sealing the system under vacuum and filling with natural gas and air as the seals were not perfect and pressure rose slowly, but noticeably if the system was left at vacuum for an extended period. This procedure was then repeated for a suitable range of concentrations at total pressures of 0.5, 0.75, 1.25, and 1.5 bar. The same considerations were made for reducing error as above. One thing to note is that at total pressures of less than atmospheric there was always a slight influx of outside air, due to the imperfect seals, however the effect of this was negligible. Experimental Results To find a correlation between the concentration of methane and the bridge output voltage we took the gradient of the initial increasing linear section of the raw data. Figure 3 below shows this for the case with concentration 5% of methane with a total pressure of 1 bar. As can be seen, the measured data falls away as reactant, the natural gas, is used up in the reaction. Figure 3 also shows that there is a very sharp spike as the output voltage varied greatly when the sensor was first switched on. This illustrates that care was needed when selecting which section of the curve to use to calculate the gradient. This is the right method to use to find concentration because, according to Hammett, â€Å"the rate of any chemical reaction is proportional to the product of the concentrations of the substances actually involved in the reaction.† [7] and the gradient of Figure 3 is a rate of reaction. The next step was to establish the gradients, or initial reaction rates, of 1%, 2%, 3%, and 4% methane mixtures. These are shown in Figure 4, along with 5%, for a total pressure of 1 bar. Figure 5 shows these gradients again, but all in order and passing through the origin to better show the steady increase in gradient. Figure 6 shows processed data for 1 bar total pressure. The gradients of the lines from Figures 4 and 5 are plotted against their concentration. This allows us to find a constant linking the raw data to the concentration for this pressure. Table 1 goes on to show the values of this constant for the other pressures analysed. The raw data for these is not shown here, but the process and data is similar to that for 1 bar. Figure 7 shows the relation between the pressure and the concentration. Also included are a second order polynomial and a linear trend line (fitted by least squares). Vertical error bars are from standard error in Table 1 and horizontal error bars from  ±0.1bar uncertainty in total pressure. Discussion Figure 6 shows the gradients of the lines in Figures 4 and 5, meaning the rates of reactions at different concentrations, plotted against the concentration of methane. This gives us a relationship between concentration and the initial rate of reaction, the quantity derived from the raw data, for a specific total pressure. For 1 bar this was 8.7 ±0.4 10-4 Vs-1 per % methane. The error in this comes from a combination of the uncertainty in the pressure measurement leading to uncertainty in concentration corresponding to  ±0.1% in the worst case and a small random error in the output voltage of the bridge circuit corresponding to  ±2Ãâ€"10-4V. Figure 7 includes both a polynomial fit and a linear fit. It is unclear if the relationship remains linear or takes some other form at low pressure. The polynomial is almost linear for the three higher pressures, which indicates a strong relationship between pressure and reaction rate for higher pressures. The values and their associated errors in Table 1 come from each plot of initial reaction rate (rate of change of voltage) against concentration for the different pressures. The error is the standard error for these plots. There was a breakdown of the relationship at low pressures. Data for 0.5 bar total pressure was not included in the results because no clear relationship between output and concentration was found. This indicates that the sensors are not suitable for low pressures, especially when coupled with low concentrations. This resulted in very little output from the sensors, making it difficult to reliably determine an initial reaction rate, which is vital for obtaining a relationship between the raw data and the concentration. The reason for this lack of output was that not enough natural gas particles were interacting with the sensitive element to cause it to heat up and also due to a lower oxygen concentration also slowing down the reaction. This is not a problem in the commercial applications of these types of sensors as they are typically used to detect high concentrations of combustible gases at atmospheric pressure. This does highlight a weakness in the apparatus when used for finding unknown concentrations, however. Another weakness was the inability to measure large pressures precisely, leading to large errors in the total pressure measurements. This has an increased effect on low pressures, which is a further reason for the less reliable data. Empirical Relationship If we give the initial rate of reaction a constant,, and a function of pressure, , then (2) where is the concentration of methane, is determined experimentally from the sensor data and is the polynomial relationship from Figure 7, (3) with the appropriate total pressure, found experimentally from the pressure sensors on the vacuum system, substituted. Using this equation it is possible to use the sensors to determine the concentration of an unknown mixture. Conclusions The aim was to build an apparatus capable of determining the concentration of natural gas in air up to 5%. In order to do this it was necessary to first establish the relationship between sensor output and concentration. This was then repeated at different pressures to understand the effect of a different pressure on the relationship between sensor output and concentration. Finally it was possible to use these relationships to determine the concentration of an unknown mixture of gas and air. The constant of proportionality for 1 bar pressure was found to be 8.7 ±0.4 10-4 Vs-1 per % methane. For 0.75 bar it was found to be 6.5 ±1.6 10-4 Vs-1 per % methane, 1.25 bar was 16.2 ±0.8 10-4 Vs-1 per % methane, and 1.5 bar was 25.3 ±1.9 10-4 Vs-1 per % methane. No correlation was found between sensor output and concentration for 0.5 bar.

Legacy and Respect: The Usefulness of Feminism Essay -- Gender Sexuali

Legacy and Respect: The Usefulness of Feminism In a letter to students who participate in Bryn Mawr and Haverford Colleges' bi-college Feminist and Gender Studies department, Head of the Department Anne Dalke outlined an argument in favor of changing the program's name. She wrote, "Our argument for re-naming the F&GS program "Gender and Sexuality" is based on 3 claims: 1. that it will be enticing for prospective and current students and faculty, because it names their personal and intellectual interests and investments (while avoiding the word "feminism," which is off-putting to a large range of individuals) 2. that it accurately represents the current state of scholarship in the field 3. that it accurately names--and invites exploration of--where the interesting questions lie." At the date in which this statement was composed last April, I probably would have agreed with its relevancy and reasoning. I no longer accept this line of thinking, however, due to my education and involvement in Anne's co-taught class I am taking this semester, Interdisciplinary Perspectives on Gender. It is ironic that I began my study of gender four years ago as a freshman vehemently against feminism, and only now as a senior taking the only class required for every major or concentrator in that field have I come to appreciate the legacy and usefulness of feminism as a theory of practice and of education. My original concepts of feminism were that it was a theory that denounced men and elevated women beyond a fair or equitable place in society. I recognize now the stereotyping that I inadvertently allowed myself to feel. "Equating feminist struggle with living in a counter-cultural, woman-centered world erected barriers that closed... ...of a more perfect understanding. Works Cited Dalke, Anne.

Cancer and Technology Essay

Over the years, technology has evolved and given us many advantages such as the breakthroughs in medical science, transportation, and the internet. Imagine your life without all of these benefits. Technology has forever changes our lives and given us new ways to see life. Can you imagine where we would be now without it? During the last 30 years medicine has reached new frontiers and many new breakthroughs that benefit the public on regular bases. Now what were once unknown diseases that could not be treated such as cancer are now able to be treated. In consequence of technology evolving and becoming more high tech, machines that allow chemo therapy and radiation are available. I am very grateful for this breakthrough in science because my grandfather had cancer and because of radiation the cancerous cells were killed and now he is able to live a long and healthy life in the sun. Another benefit that technology had given us in science is beneficial to deaf people. Hundreds of years ago these disabled people had no hope of recovering any hearing, but now there are hearing aids, and surgeries that replace impaired parts of the ear. Surgeries now are available to anyone at any time, we might take this a common action now but a hundred years ago surgeries were dangerous and done raw without any sedatives. Technology has also brought us one of the most life altering deices, The World Wide Web. The internet has, one could say, taken over our lives in practically every way. It is the number one way to require quick information which helps students, teachers, and anyone trying to gain information all by a click of a button. The internet has shown very useful when encountering natural disasters. For example during hurricane Sandy the cell phone lines where always busy or the connection was lost, so the most reliable way to communicate was through the internet via Facebook, Email, and Twitter. Another way technology has amazed me is through video chat. Instead of having to travel to see your family, you are able to see them face to face and for a brief moment you might think that they are actually there with you in the room. Another remarkable way technology has greatly impacted the world is through travel. Hundreds of years ago it was would take weeks to cross the Atlantic Ocean and now thanks to technology and planes it only takes 6 hours to cross the ocean. The concept of flying and being able to be in one country one day and in another the next still astounds me to this day. Technology also gave us buses and trains. These modes of transportation also have greatly impacted our society today. Many people rely on buses to get to and from work. Another mode of transportation that technology has created is the spaceship which has allowed us to explore different planets and given us a better understanding of the world around us. Technology seems to have completely taken over our lives. It has given us so many advantages from medical breakthroughs, and the internet, to transportation in this world and to other ones. This one discovery has impacted our lives forever and we can only imagine what other great ideas can come from it, and how it will affect our lives once more.

In the mid to late sasss, in the south, men were expected to perform yard duties while women cooked, cleaned, and nurtured the children. Kate Chopping The Awakening takes place in the sasss and urine this period of time; women were expected to be docile to their husbands and children in a patriarchal setting. Gender roles tend to become perplexed and misunderstood within the novels, The Awakening by Kate Chopin and A Perfect Peace by Daniel Black. Of these works the authors reveal inch-by-inch, the trials, tribulations, and revelations his or her may have when deciding on his or her status within gender roles. Chopin makes an effective effort to inform readers about self-satisfaction and having the courage to reveal that irrational Judgment The Awakening. Having dated back in the Victorian era, the vision of a woman yearning to expand her knowledge about anything was declared as absurd. Chopin introduces a character Edna Pointillist who, in the beginning, is assumed as the typical housewife with practical housewife duties. In truth, Edna despises her duties and begins to long for autonomy. Chopin states, A certain light was beginning to dawn dimly within her, the light which showing the way, forbids it. At that early period it served to bewilder her. It moved her to dreams, to thoughtfulness, to the shadowy anguish which had overcome her the midnight when she had abandoned herself to tears. (14). Here, Chopin explores Deans mind by exposing her emotions in parallel with thoughts from the prior circumstance. In addition to Deans person struggles within herself, Chopin focuses on the desire Edna dreams of, becoming the independent, outspoken woman that Madame Rotational exudes. She explains, She had long wished to try herself on Madame Rotational. Never had that lady seemed a more tempting subject than at that moment, seated there like some sensuous Madonna, with the gleam of the fading day enriching her splendid color. (12). Clearly, Chopin expresses the sudden desired thought of Madame Rotational from Edna while using a plethora of secretive phrases and adjectives describing such an image. Chopin also reveals Deans passive promiscuous characteristic by describing how devoted she is to Madame Ratatouilles needs. She continues: Madame Rotational folded her sewing, placing thimble, scissors, and thread all neatly together in the roll, which she pinned securely. She complained of faintness. [Edna] Mrs.. Pointillist flew for the cologne water and a fan. She bathed Madame Ratatouilles face with cologne She stood watching the fair woman walk down the long line of galleries with grace and majesty which queens are sometimes supposed to possess. (13) Chopin demonstrates the lack of limitation. Later within the literary work, Chopin gives readers the final stages in which Edna can no longer bear to follow the negative effects of gender roles. The act of suicide was foreshadowed by the undesired feeling of being a mother or a housewife hostage. Chopin illuminates, She went on and on. She remembered the night she swam far out, and recalled the terror that seized her at the fear of being unable to regain the shore. She did not look back now, but went on and on, thinking of the blue-grass meadow that she had traversed when a little child, leveling that it had no beginning and no end. Her arms and legs were growing tired. She thought of Leonie and the children. They were a part of her life. But they need not have thought that they could possess her, body and soul. How Mademoiselle Raise would have laughed, perhaps sneered, if she knew! And you call yourself an artist! What pretensions, Madame! The artist must possess the courageous soul that dates and defies. (109) By Chopin guaranteeing that Edna was going to take her life, Chopin allows readers to understand that she was not only alleviating herself from violation but undoubtedly freeing her body and soul (109). When raised a certain way from birth, the pupil becomes accustomed to the criteria of the lifestyle. In A Perfect Peace, Daniel Black takes a probing look into the puzzling and unnatural ways the character, Perfect, is transformed from the femininity to masculinity of life. Mimi have to get clear about the kind of life you can live here. Life can be lived anywhere, but not every life can be lived everywhere. (336). Black effectively points out that only being a girl or boy is a life that can be lived, but by becoming both initiate that, that particular life is ineffective. One of the most prominent characters mentioned in this literary work is named Emma Jean. Black describes the longing Emma Jean exhibits for a seventh child as a girl. He elaborates, Emma Jean wouldnt look. All she could think about was the promise she had made as a child to love and pamper a daughter the way someone shouldve loved her. Shed dreamed of stroking a little girls hair and binding it with golden ribbons, then sending her off to be admitted by the world. But that couldnt happen now. How would she ever spite her mother without a daughter of her own? (13) Black makes clear that Emma Jean has struggled with the negligence of her own mother therefore by giving birth to a girl; Emma Jean can prove her point that a daughter deserves the world. As the novel progresses, Emma Jeans conscious develops the harsh burden that has been hidden from Perfect for eight years. She can no longer take the guilt from which stems from the very day Perfect was born and must now reveal the one secret that alters the remainder of this novel. Dreading the moment like Sisyphus must have dreaded another rolling of the stone, Emma Jean rose and said, Perfect, honey, come tit me. .. No. Not Really. I mean no. When you was born I decided to raise you as a girl cause I wanted one so bad but- M)U was born a boy. I made you a girl, but that anti what you was suppose to be. (127,128). The following reveals that Perfects identity was altered and Perfect now must become Paul and abide by the guidelines off males gender role. With the unthinkable choices to follow the guidelines of gender roles, Kate Chopin and Daniel Black allow both Edna and Perfect to overcome those difficult decisions. Edna finds herself trapped between being her own self and being what she should be. Edna frequently thinks about not living the life of a feelings of displacement in a patriarchal society soon come to a devastating reality: suicide. Perfect Peace suffers from the confusion that her mother, Emma Jean has place upon her due to the sudden change of gender. Perfect not only struggles with the procedures of being a girl within gender roles, but also once revealed as born a boy. Neither Daniel Blacks A Perfect Peace nor Kate Chopping The Awakening do not hesitate in elaborating the immense pain and conflicting decisions each character faces and in order to be content with his/her self, gender must come secondary for here are no roles when being yourself.

The Disadvantages of Socialized Medicine essays

The Disadvantages of Socialized Medicine essays The topic of this paper is how socialized healthcare has disadvantages. Socialized healthcare is in the news today and is proposed by some leaders in both parties of Congress as the answer to insurance and health crises that are becoming apparent in the democratic system in the United States. Unemployment and inflation have made it impossible for many to afford private insurance and it is increasingly becoming the norm for businesses from large corporations to small businesses to not offer their employees health insurance. Today a bill to fund health insurance for underprivileged children is being debated in both houses and the President of the United States has threatened to veto it if it passes. Many people are for some sort of socialized healthcare today, but though the trend appears to be going that direction, there are factors that might be detrimental which must be considered before socialized healthcare becomes the norm. One must conclude that should socialized healthcare beco me part of the governmental system, there would be a few disadvantages that might outweigh its benefits. Great Britain is one nation which has had a National Health Service (NHS) since 1948. This initial experiment was more costly that predicted, the system was overloaded so that one in eight patients waited for over a year for treatment (Carvel, 2007, 2), the drugs administered were limited or unavailable for those who needed them, and the facilities were not up to par (Kelland, 2006, 1). Problems continue to plague the British health system, with government officials skimming funds and research lagging. One of the United States nearest neighbors, Canada, has enjoyed the Canada Health Act since 1984, when it established a publicly-financed, single-payer system and outlawed private health insurance. Although most Canadians approve of their public health system, there are problems such as long waits for specialized surgeries (Duff-Brown 1). Another...

Sustainability - Essay Example In addition, one should considering the durability of the selected materials. In bridge engineering, the constructors have opportunity to make their decisions and provide solutions that will give a balance between the environments, social impact, and economical guidelines of sustainability. The bridge to be constructed is a unique one in nature since it will be capable of opening from the middle to enable large ships and vessels to pass freely. This will require a lot of time to design, rating or assessment of materials to be used (Institution of Civil Engineers, 2001). The bridge professionals and transportation authorities should ensure that the right materials and construction techniques are used and presented in a consistent, systematic and credible way. This project will consider the development of bridge sustainability putting into consideration its three pillars, that is; social, environmental, and economical factors. The project will focus on the materials used in constructio n, but not limited to the following content: 1) What is the mentioned material? 2) Why it is a good material to be used in the construction of a bridge? 3) What are the advantages and disadvantages of it in constructing a bridge in this project? 4) How it could be good for the bridge in the long run, is it durable? 5) Comparison between the properties of the materials and how it could be improved Materials used in the bridge Materials and other resources to be used in sustainable bridge construction should be ensured to be the most appropriate materials for the site and the future maintenance in case of recycling of the structure. The constructor should include sustainable materials and should be in a position to answer several questions such as: are recycled materials used in bridge construction? What is the cost of the materials? Is the bridge designed with a complete life cycle analysis in place? The construction of the bridge in question will require the following materials (Ste ele, 2004): 1. Steel (frame, deck, and structure) 2. Timber 3. Concrete 4. Wire cables 5. Winches 6. Solar panels 7. Small Wind turbines The design and the innovation of this bridge project will be determined by the materials above. In addition, the materials selected will also address construction of lifelong maintained engineering motorway bridge. Individual materials Steel (frame, deck, and structure) Steel is iron materials made from iron ore. It is used in the construction of structures that require strong foundation and based. Steel will be used to strengthen the bridge. In order to make the bridge stronger still bar should be used to reinforce the concrete. Deck will be used to span the distance between the two ends of the bridge, since the bridge is suspended, deck will form the open truss structure to support the roadbed, preventing the bridge from collapsing. Rivets are used to join steel and the deck. Steel will form the Beams, plates, and rods shown in the proposed bridg e picture (Parag, 1999). Advantages of steel Steel makes a strong foundation of the bridge. This is because steel is one of the strongest materials used in bridge constructions. It is also used to span distances that are cannot be spanned using other construction materials such as wood. It is stronger than

Reflective Diary - Essay Example One of my pair’s friends commented that I did not give enough time for my partner to speak out. I was surprised and I reflected if I did hinder my partner’s communication in any way and why I did not become more aware of it. Using Johns Model, the significant factors that might have affected the experience (University of Cumbria, 2014b, p.2) were the limited time of the discussion, my extrovert personality, and my impatience in waiting for others to express themselves. Time was limited and I felt the pressure to rush the process of the discussion to get the results of how to speak with others. In addition, I am a friendly person and I like talking to people, which can seem like dominating conversations. In my mind, I also want to motivate others to speak by talking about my experiences, but this does not work all the time. Furthermore, I was a bit impatient in waiting for my partner to speak up. I think I do not know how to deal with shy or introvert people as much as I would like to admit because I am unsure if and when silence is something good in conversations when dealing with strangers. The next stage for the model is reflection on what I was trying to achieve and the consequences of my goals and actions (University of Cumbria, 2014b, p.2). My goals then were to express my ideas and issues about communication and to ensure that I can also learn from my partner. My constraints were time and the potentially different communication styles that we have. Time can be an obstacle to effective communication if it becomes a source of pressure to attain fast outcomes (Bruhn, 2011, p.278). Differences in communication styles can also lead to incorrect interpretations of verbal and non-verbal expressions (Solomon and Theiss, 2013, p.360). As for the consequences, I probably did not give my partner enough time to be able to fully express her ideas and opinions. I can be quite outcome-oriented, which can make me vulnerable to time pressures (Bruhn,
