Consumerism Essay Example | Topics and Well Written Essays - 2000 words

Consumerism - Essay Example On the second thought economist would not suggest such a thing if they have not seen or observed the importance of practicing it. The website thefreedictionary.com (2007) gave two definitions regarding consumerism. The first one was stated as "the theory that an increasing consumption of goods is economically beneficial, economic theory - (economics) a theory of commercial activities (such as the production and consumption of goods)" and the other one as "a movement advocating greater protection of the interests of consumers crusade, campaign, cause, drive, effort, movement - a series of actions advancing a principle or tending toward a particular end" If we are to tackle the issue with regards to the contribution of citizenship to it, consumerism as a theory on increasing of consumption of goods is beneficial, and then this claim would be in effect if the support of the citizen pertaining local goods and services is evident. ... The first thing that a local consumer must consider and think is the fact that local products are dependent on local consumers and local market and producers deem the importance of local market more than foreign market- the need here is the support of the local market in order for the local products to earn its name and made an impact to the society. Like the stages that most of the producers and marketers undertake, considering and penetrating the local market is their outmost priority in order to earn its reputation and to be able to penetrate a much higher market like the foreign market. In this case, it is established that the need of the support of the local citizens where the product has been produced. To further understand the aforementioned premise and the study per se, it is important to know the definition of citizens as a local market. The definition as well as recognition of these people as an important part of consumerism would further help us in analyzing their participation in this study. The website wikipedia.com (2007) implied two meaning with regards to citizenship. The first definition reads as "citizenship is membership in a political community (originally a city or town but now usually a country) and carries with it rights to political participation; a person having such membership is a citizen. It is largely coterminous with nationality, although it is possible to have a nationality without being a citizen (i.e., be legally subject to a state and entitled to its protection without having rights of political participation in it); it is also possible to have political rights without being a national of a state" In the given definition of wikipedia, its second definition seems to be the appropriate area of interest in this study.

The Gospel Unhindered Research Paper Example | Topics and Well Written Essays - 1500 words

The Gospel Unhindered - Research Paper Example However, despite rebellion from the Jews, the gospel continues to be propagated throughout the world. This brings forth the very last word of Luke’s account of Acts, akolutos, which when translated means unhindered (Frank 460). Definition and Translation of Unhindered. The last word of the extant text of Luke’s Acts is akolutos which when translated means unhindered (Frank 460). This underlines the essence of Luke’s writing as evidenced in the word hinder as used on a various occasions. Philip found nothing to hinder the Ethiopian eunuch from being baptized (Acts 8:36). Moreover, in his defense for mingling with uncircumcised men, Peter stated that he would not hinder God (Acts 11:17). Therefore, the usage of the word hinder by Luke outlined the unhindered nature of the gospel. Timeless Application. Luke wrote the book of Acts at a time when the gospel was predominately acceptable among the gentiles. However, the Jews remained adamant to the gospel. It is necessa ry to note their adamancy did not hinder the gospel from being propagated to other communities. Consequently, even acts of violence from the Jewish community such as the stoning of Stephen and the expulsion of Paul from synagogues did not prevent the gospel from being propagated. As a result, the power of the gospel remains unhindered today, just as it was during the early church period. Breaking through Barriers PERSECUTION Early Church. The early church underwent immense persecution. In the inception of the propagation of the gospel, Peter and John were arrested and threatened (Bock 436). Moreover, the apostles were also imprisoned by the Sadducees (Acts 5:18). This was as a result of the Sadducees’ jealousy towards their flourishing ministry. Later on, Stephen became the first martyr of the early church as he was murdered for defending the gospel. Stephen’s death resulted in the scattering of the early church as the disciples fled from Saul to the Diaspora. However, Saul was eventually converted into a preacher of the gospel. Nevertheless, just like the other Christians, he also underwent numerous persecutions in the ministry (Paul 323). Present Day. The church still undergoes persecution even in the modern day as evidenced in the prohibition of Christianity in various countries (Soci?as 133). For instance, in North Korea, practicing and propagation of Christianity could be tantamount to gross persecution from the authorities. Persecution occurs in the form of violence, imprisonment and in extreme cases, death. Therefore, persecution of the church still occurs even in the modern day. However, it is highly prevalent among the Muslim, Asian, Chinese, Korean and Indian communities. As a result, Christians from these countries have been forced to flee to other Christian-friendly countries. Therefore, despite being in a modern world of civilization and freedom of religion, the church still receives immense persecution from the anti-Christian commun ities. ETHNIC AND CULTURAL PREJUDICE Philip and the Ethiopian Eunuch. The Spirit of the Lord leads Philip to an esteemed person in the Ethiopian government. The eunuch was in charge of treasury in the land of Egypt (Acts 8:26). Nevertheless, he was not an Israelite. Thus, according to the Jewish culture, he did not qualify to be part of the Jewish family. This is because he was unclean and uncircumcised. However, despite his inadequacies, Philip reaches out to the eunuch and preaches to him. This is further evidenced when they come across a river and

Improving Car Chassis Stiffness

Improving Car Chassis Stiffness Introduction The purpose of the project is to increase the stiffness and reduce the weight of the existing car chassis, without disturbing the shape provided for engine mountings and drivers space and other constraints provided by the existing chassis model. Why is it so important to increase the stiffness and reduce the weight of the chassis? In general to define chassis in this way, first a clear meaning of structure should be known. In general perspective a structure can be defined as a specific arrangement of material to resist loads. This structure should also enable to the location of the components such as engine mountings, transmission, fuel tank, suspension system etc. So it must resist loads without breaking, and without more deflection. If the chassis cannot resist loads it leads to a serious handling problems, and will not support the engine and transmission system, also the chassis should be light enough to maintain weight to power ratio and better handling in corners. 1.1 Background to project The principle loads that includes on the chassis are, by the engine, the aerodynamics, brakes, road irregularities, the inertia loads due to masses under accelerations and vibrations. Also the chassis must with stand impact loads, having absorbed part of crash energy by deformation which includes the bending, torsion, combined bending and torsion, also lateral and longitudinal loads. So the chassis structure should be strong in stiffness in design case rather than strength. The chassis and body developments should also reduce weight because it improves the vehicle ride, handling, improves the performance of car by reducing the drag because of high weight to power ratio, and also will reduce the need for power there by increases the fuel efficiency. Because of this now even mass produced passengers cars lightened up by the most detailed weight-watcher engineering techniques due to corporate Average Fuel Economy (CAFE) regulations of the federal government. Lighter vehicle requires less power, hence less fuel, for equal performance. History The demand for the chassis with high torsion stiffness and low weight had increased from the World War 2. This demand had led to the innovation of many kinds such as Space frame, stressed skin etc. These types had become universal among the European road race cars following its appearance in the Lotus MK and the Mercedes-Benz 300SL in 1952. These are the cars which used strictly space frame chassis and the attention they received had popularized the idea. Major automobile industries in present era are purchasing the competitive vehicles and disassembled them carefully to study the weight and stiffness of car for comparison with the equivalent part of their own vehicle. So this lead to a competitive reasons than for increase fuel economy. Today have been included to expand the following three reasons: A means for recognising opportunities for overall weight reduction for better fuel economy. The means for determining centre of gravity (CG) location and polar moment of inertia. Detail weight estimates provides target figure of cost estimates of all parts. To resist inertial loads under accelerations, accidents etc. Structural efficiency A designer can achieve enough stiffness for a chassis from any form of construction, if enough material is used. This is not the criteria of a designer, to assess the efficiency of structure its stiffness must be considered in relation to the weight. The below shows the absolute increase in stiffness achieved in recent years is the increase in stiffness to weight ratio.

Literature Review Introduction: The loads that are experienced on a chassis are light commercial loads due to normal running conditions are considered. That is caused as the vehicle transverses uneven ground as the driver performs various manoeuvres. Basically there are five load cases to consider. Bending case. Torsion case. Combined bending and torsion case. Lateral loading. Fore and aft loading. 2.1.1. Bending case This type of loading is caused due to the weight of components distributed along the frame of the vehicle in the vertical plane which causes the bending about y-axis. The bending case depends mainly on the weight of the major components in the car and the payload. First the static condition is considered by determining the load distribution along the vehicle. The axle reaction loads are obtained by resolving the forces and by taking the moments form the weights and positions of the components. 2.1.2. Torsion case The vehicle body is subjected to the moments applied at the axels centrelines by applying both upward and downward loads are at the each axle in this case. Because of this it results in a twisting action or torsion moment about x-axis of the vehicle. The condition of pure torsion does not exist on its own because of the vertical loads always exist due to gravity. However for the calculation purpose the pure torsion is assumed. The maximum torsion moments are based on loads at the lighter loaded axle, its value can be calculated by the wheel load on the lighter loaded axle multiplied by the wheel track. The loads at the wheels are shown in the above figure. So the torsion moment is given as: RF  tf =  RR  tr 2 2 Where tf  and tr  are front and rear track respectively and R  f  and Rr  are front and rear loads. These loads are based on the static reaction loads but dynamic factors in this case are typically 1.3 for road vehicles (Pawlowski, 1964). 2.1.3. Combined bending and torsion In practice the torsion will not exist without bending as gravitational forces are always present. So the two cases must be considered when representing a real situation. Fig3: combined bending and torsion. 2.1.4. Lateral loading This type of loading is experienced by the vehicle at the corner or when it slides against a Kerb, i.e. loads along the y-axis. The lateral loads are generated while cornering at the tyre to ground contact patches which are balanced by the centrifugal force MV2  / R, M stands for vehicle mass, V vehicle velocity , R is the radius of the corner. The disaster occurs when the wheel reactions on the inside of the turn drop to zero, that means that the vehicle ready to turn over. In this case vehicle will be subjected to bending in x-y plane. The condition that applies to the roll over is shown in the below figure and it also depends up on the height of the vehicle centre of gravity and the track. At this particular condition the resultant of the centrifugal force and the weight that passes along the outside wheels contact patch. And hence lateral acceleration is V2/R=gt/2h Lateral force at the centre of gravity MV2/R = Mgt/2h. Front tyre side forces YF  = Mgt b/2h(a+b). At the rear tyres YR  = Mgt a/ 2h(a+b). From the lateral acceleration it is clear that it is t/2h times that of the gravitational acceleration. Kerb bumping will cause high loads and will roll over in exceptional circumstances. And also this high loads will cause in the bending in the x-y plane are not critical as the width of the vehicle will provide the sufficient bending strength and stiffness. 2.1.5. Fore and aft loading At the time of acceleration and breaking longitudinal forces will come into picture along the x-axis. Traction and braking forces at the tyre to ground contact points are reacted by mass times acceleration inertia forces as shown in below figure. The important cases such as bending, torsion, bending and torsion will come into play as these determine the satisfactory structure (Pawlowski, 1964). 2.1.5.1 Longitudinal loading At the time of vehicle accelerates or decelerates, the inertia forces are generated. The loads generated can be transferred from one axle to another by the inertia forces as the centre of gravity of the vehicle is above the road surface. While accelerating the weight is transferred from front axle to the rear axle and vice versa at the time breaking and decelerating condition. To have a clear picture of forces acting on the body a height of the centres of gravity of all structures are required. And its not so easy to determine. A simplified model considering one inertia force generated at the vehicle centre of gravity can provide useful information about the local loading at the axle positions due to breaking and traction forces. Front wheel drive, the reaction on the driving wheel is: RF = Mg(L-a) Mh(dV/dt) L Rear wheel drive, the reaction on the driving wheel is: RR = Mga + Mh(dV/dt) L In braking case the reactions on the axles are: RF = Mg(L-a) + Mh(dV/dt) L 2.1.6. Allowable stresses From the above discussed loads it is clear that it will induce stresses in all over the structure. So it is important that under the worst load conditions that the stresses induced into the structure are kept to acceptable limits. In consideration of the static loads of a limited amount should give a stress level certainly below the yield stress. If analysed the bending case for a road gong car is considered the maximum allowable stress should be limited as follows: Stress due to static load Ãâ€"Dynamic factor ≠¤ 2/3Ãâ€" yield stress. The above equation says that under any worst load condition the stress should not exceed 67% of the yield stress. Alternatively the safety factor against yield is 1.5 for the worst possible load condition. 2.1.7 Bending stiffness It is equally important to consider the bending stiffness weather to say the structure is sufficiently strong or not. So an equal and important assessment is given to the structural stiffness. Therefore many designers consider the stiffness is most important than strength. It is possible to design a structure which is sufficiently strong but yet unsatisfactory because of insufficient stiffness. Designing for acceptable stiffness is therefore often more critical than designing for sufficient strength. For vehicles the bending stress is determined by the limits of deflection of the side frame door apertures. In case of excessive deflection the doors will not shut properly. Local stiffness of floor is also important because it minimises the safety of the passenger. 2.1.8 Torsion stiffness If the stiffness is low the driver may feel that the vehicle in front will be shaking with the front wing structures moving up and down. The practical problems of doors failing to close properly will also be seen. A similar thing will be seen in the jacking points that are positioned at the corners of the vehicle. For fast moving cars the torsion stiffness is very important because it may cause serious handling problems. Therefore care should be taken in maintaining sufficient torsion stiffness. So from the all above dimensions of forces and handling of a vehicle chassis should be stiff enough and also should be less in weight. 2.1.9 Chassis types Chassis are classified into several types they are: Ladder frames. Cruciform frames. Torque tube back bone frame. Space frame. Monocoque. In the present era of automotive industry designers are using the space frame and monocoque for the justification of design problems and to sufficient structural stiffness. 2.1.9.1 Space frame A space frame chassis is a development of four tube chassis, both of them look quite similar. But the space frame differs in several key areas and offers very good advantages when compared to the predecessor. A space frame is an arrangement of many straight tubes in which the loads acting are either in tension or compression. The figure below shows the clear idea of a space frame. But from the above figure it is clear that the diagonal member is pulled in tension when a load is acted on it. This above illustration is the simple idea of the space frame chassis. This experiencing of loads in either tension or compression is a major advantage. So none of the tubes will be subjected to the load will tend to bend in the middle. Since the space frames are very good in torsion stiffness. The three dimensional space frame chassis are used for specialist cars such as sports racing cars. This type of vehicle design is used for low volume and mass production as well. In this type of structure it is imperative to ensure that all planes fully triangulated by doing so the beam elements are essentially loaded in tension and compression. In the space frame welded joints are done it retains bending and torsion at the joints, but to rely on this restrains will render the structure less stiff. The stiffness is provided by the diagonal member subject to direct tension or compression. 2.1.9.2 Space frame principles A space frame is three dimensional arrangements of tubes loaded in pure tension and compression. The joints between them can be replaced by the ball joints without affecting the stiffness. Other important feature is all loads enter and leave the structure at the points of intersection of three or more tubes. The structural elements do not have to be tubes and the joints do not have to be welded. In terms of torsional stiffness the space frame attempts to connect the four spring anchorages so that is impossible to twist the pair without stretching and compressing the tube. AIMS The first thing to undertake this research is to set some basic aims that need to be achieved. As the aim of the project is stated to reduce the weight and increase the stiffness of existing vehicle chassis. So the main aims are in terms of weight, stiffness, and size. 3.1. Weight Weight was a main consideration in the research it is very crucial to reduce it to that of original weight. It helps in improving the weight to power ratio, better fuel efficiency and performance. 3.2. Stiffness It is also another key factor to be considered in the research. The stiffness must be improved to that of existing one in case of torsion, bending. 3.3. Size Last but not the least, the above reduction in weight and increase in stiffness must be achieved without effecting the size and shape of the chassis. This is important because it should not affect the driver to get in the car, and appearance of the car. And also the constraints set for the positioning of the engine etc should not be changed. 3.4. Requirements Certain requirements beyond my research boundary and aims are needed to be specified, to make up and achieving success in my research they are: The elements in the space frame which should not disturb must be specified. The dimensions of the chassis, and the materials used must be specified. The specification of the loads on the chassis. The original weight of the chassis which is going to be modified. The stiffness that chassis must be in terms of torsion, bending. Project Objectives The objectives of the project are: To analyse the original chassis, its structure, weight, stiffness, torsion, and materials used. Research the characteristics of space frame chassis and discover the effects with respect to vehicle handling and performance in case of bending and torsion loads. The benefits and performance of materials when replaced by the original one in terms of weight and stiffness. The research should be done with resources available. From testing and changing the elements, dimensions other than the constraints in lab, modifying the improvements in chassis. Analysing the results to that of the original chassis and comparing. Research Questions What are the materials used for the chassis construction? What are positions in the chassis which should not be disturbed? What is maximum allowable weight, stiffness and loads that being subjected by the chassis? What will be effect on stiffness and weight if certain elements of the chassis were replaced by the other materials? If the diameter and size of the elements were changed what will be the effect on weight and stiffness? If the positions of the elements other than the elements which should not be disturbed, i.e. by mix and matching, replacing the positions. What will be the effect on stiffness and weight? If the circular tube cross-sectional elements of the chassis in some areas are replaced by square tube cross-sectional elements, what will be the effect on stiffness and weight? Research Approach and Design 6.1. Introduction The problem being researched is quantitative rather than qualitative. It deals in numerical values and variables, predetermined categories, focuses on specific knowledge and control of variables. The approach of this research is different to that of qualitative research which would involve human subjects, questionnaires and interviews. The approach will be analytical which will include experimental analysis, analysing the data, interpreting the results, comparisons etc. 6.2. Approach and design The research is about how to increase the stiffness and reduce the weight of existing vehicle chassis. The research is based on a lot of literature, experimental design and analysis. It should be well designed, planned and managed to ensure that the results can be analysed, interpreted and presented. Throughout the period of the research a process was followed to produce a successful report on the analysis done with that of the original chassis they are: Setting some benchmarks in regarding to the design of chassis. Analyse the previous chassis, and getting an idea in terms of stiffness, weight, shape. Developing the modelling, and analysing techniques that allows the process to be simple and can be modified easily. Gaining the information regarding the dimensions of the chassis from the designers and the areas in the chassis which should not be disturbed in terms of design. Looking for the possibility of the new considerations that were not previously included in the design. Considering the feedback of the supervisor as the process of the research goes on. 6.3. Experiment design It includes a statement of problem to be solved. Before going to do the research on the experimental design it is important to consider all points of view of what the experiment is intended to do. 6.3.1 Response variable The problem must include reference to at least on characteristic of a unit on which information is to be obtained. Those characteristics are called response or dependent variables. In this research the response variables are weight and stiffness, which are dependent on material, design, etc. In addition to reference of the response variable, some questions should be asked. They are measurements methods, what tools are required to measure the variable? Can variable can be measured accurately or not? 6.3.2 Independent variables The variables which control the response variables are called Independent variables. In this piece of work the independent variables are: Load on the space frame chassis. Material used for the chassis. Design of the chassis. Size and shape. The independent variables will be chosen randomly one at a time or by considering more than one independent variable. The response on the dependent are analysed and compared to that of original chassis. 6.3.3. Design Before the data is collected and results are drawn, it is important to know how to solve the problem with a limited amount of time and available resources. It is important to note how many observations should be taken, what is the maximum amount of deviation in terms of stiffness and weight in comparable to original one. Also attention is required in handling the independent variables. 6.3.4. Analysis comparison The final step in the experiment is to compare the results of the optimised chassis to that of the results on the original one, and approach the problem by checking and comparing the results. This will be done by the preparation of the graphical displays of the values in terms of weight and stiffness. Its important to make sure that the results are within the prescribed limits. If its not, follow the investigation again by controlling the independent variables. 6.4. FSAE chassis Rules and Requirements.

Indecision, Hesitation and Delay in Shakespeares Hamlet Essay

The Indecisiveness and Hesitation of Hamlet  Ã‚        Ã‚  Ã‚   In the Shakespearean drama Hamlet considerable literary critical comment swirls about the subject of the hero’s hesitation or indecision in the prayer scene. Is it weakness? Is it representative of a mental condition? Are there other incidences of hesitation? Let us explore the subject in this essay and interpret the key scene in light of other scenes, with input from literary critics.    David Bevington, in the Introduction to Twentieth Century Interpretations of Hamlet, eliminates some possible reasons for Hamlet’s hesitation in killing Claudius during the prayer scene:    Several limits can be placed upon the search for an explanation of Hamlet’s apparent hesitation to avenge. He is not ineffectual under ordinary circumstances. Elizabethan theories of melancholy did not suppose the sufferer to be made necessarily inactive. Hamlet has a deserved reputation in Denmark for manliness and princely demeanor. He keeps up his fencing practice and will â€Å"win at the odds† against Laertes. He threatens with death those who would restrain him from speaking with the ghost – even his friend Horatio – and stabs the concealed Polonius unflinchingly. On the sea voyage to England he boards a pirate ship single-handed in the grapple, after having arranged without remorse for the deaths of Rosencrantz and Guildenstern. In light of these deeds, Hamlet’s self-accusations are signs of burning impatience in one who would surely act if he could.

Evolution of Women in the Military

The Evolution of Women in the Military Abstract Women are without doubt an integral part of the military services. It took the determination of women throughout history to pave the way for the 400,000, women that serve today. From the early years of the military to the present conflict in Afghanistan, women have made continuous progress towards equality. It is through their contributions that the military has evolved, consistently opening more jobs to women in combat. Time has proven that war does not discriminate; a successful military uses the strengths of all members despite their gender.The Evolution of Women in the Military Women in Military History Although not officially enlisted into the services, women have been a part of the military dating back to the American Revolutionary War. Throughout history, they have challenged the norms of society and pursued their dedication to the Nation, fighting for our freedom. Women in the military have fought through challenges and obstacle s in both fighting for equality and establishing their roles in combat. It is clear that the military services would not be what they are today without their contributions and sacrifices.The Early Years From the American Revolutionary War through the Civil War women contributed to the war in both conventional and unconventional ways. In serving as what we would call today Combat Service Support, they took care of the wounded, brought water to troops, provided laundry services, and served as cooks. Many women directly supported the cause by disguising themselves as men in order to fight in the war. Two such documented cases were Deborah Sampson during the American Revolutionary War and Elizabeth Newcom during the Mexican War.Sampson served in the Continental Forces for over a year, she only earned half of the pension the men received during that time. Newcom enlisted in the Missouri volunteer Infantry and marched for over 600 miles. Once discovered, the military discharged her with n o benefits. There were also several women who fought alongside their husbands with no pay or benefits. If their husbands received wounds during the conflict, they did not hesitate for a second to step in and continue the fight. One of the most well-known women of the Civil War was Dr. Mary Walker.She was unable to find a paying job in the military simply because she was a woman, She volunteered on the front lines, saving thousands of lives. Although the military did not call these women â€Å"Soldiers,† at that time, I would argue that their actions and contributions whether directly in the fight or support were that of Soldiers. From the Spanish American War in 1898 to 1908 women continued to progress. With the number of casualties from the war overwhelming the medical system, the military services were in dire need of help. They had no choice but to allow women into the services, but continued to restrict them as contract workers only.By the war’s end, the Army hired over 1,500 nurse contractors that served at hospitals throughout the world. The performance of the contract nurses was not without notice; this prompted Dr McGee to write legislation creating a permanent corps of nurses. This was a major turning point for women in the military, which resulted in the first woman appointed as the Acting Assistant Surgeon General, Dr. Anita Newcomb McGee. It was evident that the Army could not meet the demands of the war without the use of women resulting in the establishment of the Army Nurses Corp in 1901 and the Navy Nurse Corp in 1908 (â€Å"Highlights in History,† n. . ). The period of World War I and World War II brought significant advancements for women in the military although it would prove that women were expendable. After the passing of the Selective Service Act and the draft initiated, there were over 4. 8 million men served fighting in the war. This had a significant impact on the women of the nation not only were they needed to f ill the millions of jobs left on the home front, but the military needed the women to free the men of noncombatant duties. The Navy and Marines were the first to enlist women ignoring red tape from congress.The Navy enlisted over 12,000 Yeomen and 1,500 nurses and the Marines enlisted over 300 women in the reserves as telephone operators and clerks. The Army unofficially enlisted over 21,000 nurses as contract workers and volunteers. The Army Signal Corp trained over 300 bilingual telephone operators and stenographers. At the end of the war, the military did not recognize women for their service or consider them Veterans. For example, the telephone operators left the military with little appreciation, receiving no ceremonies and no formal discharge or benefits. These women erformed duties no less important than the men did and the mission would have failed without them, yet the military was able to dismiss them with no concern for their contributions. In 1979, the Army reviewed the women’s service and determined that they performed duties as any other Soldier had. They gave them full recognition; unfortunately, for many it was too late, they passed away never receiving the title of â€Å"Veteran. † As women volunteered for service for a resistant military, compared to the many men that the government drafted it was clear the military did not appreciate their commitment, sacrifices and value the worth of women.This was evident by the Army Reorganization Act in 1920, which granted military nurses â€Å"relative rank† of an officer, not receiving the same pay, benefits, and privileges as that of male officers of the same rank (â€Å"Chronicles of,† 2007). As World War II began, the military could not ignore the contribution of women during World War I and knew they could not fight another war without them. During World War II, over 400,000 women served in the military in both the United States and Overseas. We know World War II for the number of women that served; emphasizing both the need for women in the military and their commitment to duty.However, women would bear many challenges during this time. Women in the military continued to go against the norms of society that considered womens place to be at home taking care of the home and family. The majority of men in the military did not accept them as equals; although they held many positions previously only held by men. The problems with date rape and slander continued. According to Gruhzit-Hoyt (1995), a quote heard often among men in the Navy, they had â€Å"joined the navy to ride the WAVES† (Women Accepted for Volunteer Service).These challenges continue to exist even in today's military. Highly trained women were underutilized and ranked far below their duties and responsibilities. It was common for higher ranking individuals to assign some women as babysitters and personal servants. The Corps of Engineers and Medical Services used their assigned w omen as â€Å"mop commandos† (Weatherford, 1990). One example is of a private named Mary McMillin. She held the womens world altitude record in parachuting, having jumped from 24,800 feet and known for her work as a daredevil in the flying circus.Her duties in the Army were to pack parachutes for young men who had never jumped before in their lives (Weatherford, 1990). The rank of women during this time was far below that of men. One such case was Oveta Culp Hobby; she was responsible for over 60,000 women, formed an organization from scratch, and took on complex missions. Her rank was Colonel, which compared to the rank of a man who would command no more than 500 Soldiers (Weatherford, 1990). These are only a few examples but women felt the inequality throughout the military for many years.Women not only had the issues of being a female in the military, but they dealt with the same issues that the men did being at war. They had substandard living conditions, which were somet imes worse than the mens, lack of supplies and fear of the Enemy. In 1942, the Japanese held sixty-seven women for over two years as Prisoners of War (POW). They also captured five Navy nurses holding them for five months and a second group, holding them for 37 months. The Japanese treated the women worse than the men POW, raping and harassing them on a consistent basis.These events further supported the view of the majority of society who believed the military service was no place for a woman. This did not stop women from fighting to be in the services. By the end of the war, the military made significant strides in establishing women into the military. All services had developed either a corps or reserve for women; the Army established the WAC, the Air Force established the Women Air force Service Pilots (WASP), the Navy established the Women Excepted for Volunteer Emergency Service (WAVES), and the Marines and Coast Guard established the Women’s Reserves.It is hard to imag ine how the war would have ended without the 400,000 women that served. Nether less, it was clear that history would repeat itself and once again, the military dismissed the majority of women even if more qualified than their male counterparts. Time for Change The years following World War II through Post Korean War would bring much change and initial uncertainty for women in the services, yet would prove to be a time of positive and lasting change. In 1945, the WAC closed for enlistment, closing all training centers.The number of women in the WAC decreased from over 150,000, to barely 3,000. Although some women were happy to return home to their lives before the war, found that they had the need and passion to do more. The Army realized the need to maintain women in the regular Army, therefore, a year later the Army Chief of Staff Gen Dwight D. Eisenhower began the process of making the WAC a permanent part of the Army. After three years with Lt. Col. Mary Louise Milligan leading t he way, President Truman signed the Women’s Armed Service’s Integration Act. This was a historic time for women throughout all services.The first enlisted women entered the Regular Army was in July 1948, and the first WAC officers received Regular Army appointments in December 1948 (â€Å"Women in the,† n. d. ). This opened the door for the military to recognize women for their service and made it possible for women to make the military a career. It was through the Korean War and the years following that women would begin to understand what being part of the Regular Army would mean. The Army recalled many Officers for duty and involuntarily extended those enlisted that had planned to leave the military.More than 500 women served in the combat zone. The Koreans killed Seventeen women during the war, which was considerably less than World War II; fortunately, the military gave these women the same courtesies and benefits as the men. Following the Korean War, more positions opened to women, and training available for women increased tremendously. A true testament to women fully integrating into the services is the addition of reenlistment bonuses and pay increases and for the first time implementation of uniforms for women.Women could finally say that they were officially part of the United States military organization although the battle for true equality was far from won. The military’s expectations of women were in contradiction to the growing feminist movement in the United States during the Vietnam War but would eventually have to adhere to the expectations of the nation (â€Å"Highlights in History,† n. d. ). The military expected women to look like women. They were to dress appropriately in skirts and high heels, where make up, and use appropriate ladylike manners.These guidelines even applied to the women in Vietnam. The military spent money to retrain women to perform what they considered a womens work, such as typing a nd cooking, even if trained and proficient in other technical skills. These actions further restricted promotions for women making them uncompetitive and ineligible for promotion to Admiral or General. Eventually the military could no longer go against the demands of female service members for equality; congress voted to allow womens promotion to higher pay grades to include Admiral and General in 1967. â€Å"Women in the,† n. d. ). This movement would propel many firsts for women throughout the Vietnam War to include; first woman enlisted in the Air National Guard, promoted to Brigadier General, aircraft maintenance officer, promoted to Major General, first naval vessel sails with female and male crew, and the Army’s first woman helicopter pilot. Although this was a step in the right direction, there was still a long road to equality. The Armed Services Committee of the US House of Representatives made the following statement making that clear. †¦ here cannot be complete equality between men and women in the matter of military careers. The stern demands of combat, sea duty, and other types of assignments directly related to combat are not placed upon women in our society. †¦ It is recognized that a male officer in arriving at the point where he may be considered for general and flag rank passes through a crucible to which the woman officer is not subjected—such as combat, long tours at sea, and other dangers and isolation (â€Å"Women in the,† n. d. ). From the post Vietnam Era to the present, women continued to earn their way to the highest ranks in the military.They took on the toughest jobs and assignments and proved that they were as capable as men to complete the most complex missions. During this time, women enter into the service academies and graduate, a woman commands a major military installation, the first African-American woman promoted to Brigadier General. During Operation Just Cause in Panama, two woman Com mand companies and the list continues. Women would continue to show their relevance through Operation Iraqi Freedom and presently in Operation Enduring Freedom.Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) would prove to be both a time for women to excel and time of great challenges for women in the military. There have been more women killed in OIF than in any war since World War II with over 200,000 deployed. Unfortunately, the war itself has not been the only challenge. The biggest challenge has come from within our own ranks. According to several studies of the US military funded by the Department of Veteran Affairs, 30% of military women are raped while serving, 71% are sexually assaulted, and 90% are sexually harassed (Benedict, 2009).While deployed leadership issues women whistles, ordered them to stay with battle buddies. Is this what a Soldier deserves while fighting for her country? With the increase of sexual misconduct, the military has taken a more proactive approach to training and has given victims more options for reporting. Although not officially authorized to serve in direct combat, they are. They conduct patrol, female searches at checkpoints and serve as pilots just to name a few. This has led to the debate of womens roles in combat. Womans Roles in Combat Women’s roles in combat have been a subject of debate.Both in the military and within society, people believe that women do not belong in direct combat or on the front lines. Those that do support women in combat argue that some, not all women are just as capable as men to perform combat duties and should be afforded the same opportunities as men in the military. There are compelling arguments on both sides, but the truth is that women will continue to fight for equal treatment in all facets of the military. Although the thought of women fighting on the front lines of combat is at times difficult to imagine, it is reality.There are concerns with physical capab ility, mental ability, and effects on the unit. The opposition says that women are caretakers, nurturers, life givers and everything that combat entails goes against those roles. Combat as defined by General Robert Barrow, former commandant of the US Marine Corps, â€Å"exposure to danger is not combat. Being shot at, even being killed, is not combat. Combat is finding†¦closing with†¦and killing or capturing the enemy. It is killing, and it’s done in an environment that is often as difficult as you can possibly imagine†¦Brutality.Death. Dying. It’s uncivilized! And women can’t do it† (Muir, 1992, p. 3). This statement is very broad and stereotypes all women. However, not all women are the same and many women want the same opportunity to fight and die if need be for their country. Another common argument is that women do not have the physical strength and stamina to conduct combat missions. Most would agree that the majority of women, as wit h many men, are not physically capable to perform combat duties. Therefore, the military should develop a physical test to determine MOS eligibility.This would enable the most qualified personnel to perform in combat, regardless of sex. Is a woman mentally capable of killing, can they pull the trigger? Women may go through a different decision-making process than a man, although with training, and mission analysis, they will do what they have to do. Combat has an effect on all service members. Women will have post combat issues, but no different than men. Effects on the units can be minimal if the military develops a slow and deliberate plan to integrate women into the units.Change is difficult, but we are a Military that must adapt to a constantly changing environment. As with the repeal of â€Å"Don’t ask, Don’t tell† it is the leader’s responsibility to educate, train, and enforce changes that in the end state will only make us a stronger military. The Military Leadership Diversity Committee is currently in support of women fulfilling combat roles. It is clear that women have been serving in combat roles unofficially for years. Units have cleverly attached women to combat units instead of assigning them or simply tasking them to perform missions in direct combat.The mission will place many women not attached or tasked in direct combat with the enemy meeting the exact definition of General Robert Barrow. Therefore, the reality is that women are on the front lines, and it is time that the military opens all jobs to women. Considering the major contributions of women, and the impact they had on the military, it is imperative that the military gives women the same opportunities to serve their country as their male counterparts. Contributions of Women throughout History Many legendary women throughout military history are not well known.Early in history they did not serve in legitimate roles; therefore, nobody wrote about or recognize d them until many years later. Yet it is important to understand without their contributions things may be different today. Catherine Moore Barry was primarily responsible for General Morgan defeating Gen Cornwallis at Cowpens during the Revolutionary War, which ultimately resulted in the Colonies winning their independence from Britain. Rose O’Neal Greenhow who became one of the best-known spies during the Civil War sent a message to Gen Beauregard resulting in him taking Bull Run.Col Ruby Bradley who is the most decorated Army Nurse served for 34 years, participating in the WWII and the Korean War. More recently, Maj Marie Therese Rossi, she was the first female combat Commander to fly into battle. She paid the ultimate sacrifice when her helicopter crashed in March 1991. Finally, Sgt Leigh Ann Hester who is the first female to receive the Silver Star Medal since World War II. These are only a few examples of woman’s contributions throughout the years, but if they ha d been there where would we be today. ConclusionFrom the days of the Revolutionary War when women disguised themselves as men to fight in the war to today when women are closer than ever to equal treatment as the men they serve alongside of, they have endured through numerous challenges and obstacles. Women battled against sexual harassment and assault, rape, slander and unequal pay and benefits. During the early wars, many underestimated the value of women. Commanders in charge did not want women in their ranks. As time and war, progressed Commanders had a newfound respect for females in their units and would ask for them over the men.Although the military had become dependent on women to fill the noncombat positions, they immediately discharged them at the war's end until 1948 when they enlisted in the Regular Army. From this point on women had fought the uphill battle to today in 2012 when congress opened another 14,000 jobs for women closer to the front lines. Through their cont ributions, sacrifices and determination women’s relevance in the military is clear; they have challenged the norms of society and assisted in the success of the military we know today as the best in the world.

My “Eight Cow” Bracelet Essay

â€Å"Beauty is only skin deep† was a phrase I heard quite often during my awkward childhood. When I was a baby, I had two chins, Michelin Tire legs, and hair that stuck straight up even though it was easily over two inches long. My mom would often dress me in only a diaper on hot days inspiring my uncle to label me with the name of â€Å"Marshmallow Butt.† It was a name he was quite fond of calling me, even years later. As I grew, the double chin turned into one and a half, the legs stretched into colonial columns, and the hair eventually lay flat. This all happened just in time for puberty-acne and my first training bra when I was only ten. It was during this transitional point in my life that my father began to teach me a valuable and significant lesson regarding beauty and the power of words. During my childhood, my family indulged in a weekly ritual we called family night. We used this time for various activities. We would hold family councils where we truly believed we had a say in important subjects. We would play games and have lessons such as â€Å"being kind to your family† or some other moral issue of the time. Sometimes we would sing songs, hear stories from Dad who could rival Mark Twain any day, or spend an hour to two eating ice cream and playing at the park. I am the second child and oldest daughter in a family of ten children, so these weekly â€Å"get-togethers† rarely went without some type of fiasco. These fiascoes varied from kicking at one another as Mom was teaching us about â€Å"Doing Unto Others† or my older brother Bill and I having a hair pulling fight, not just a tug-of-the-hair fight, but a fist-full, pull-as-hard-as-you-can, you-let-go-first hair fight. It was for one of these activities that my dad brought home a movie entitled Johnny Lingo. The story was simple, but for a shy ten-year-old girl who had long, stringy, brown hair, big brown eyes, a freckled face, and who looked as though the Pillsbury Dough Boy was her closest relative, it was a story filled with magic and hope. The movie told of a girl named Mohana. Mohana was, quite frankly, the ugliest girl on the island. She was all â€Å"skin and bone.† She rarely washed her hair and never combed it. She spent all her time hiding in the woods so no one could see her and make fun of her. Even her father called her â€Å"Mohana, you ugly.† One day, the most handsome young man in the area, Johnny Lingo, came to the island and chose Mohana for his wife. He gave her father eight cows as a gift in exchange for Mohana. No one had ever given more than four cows as a gift for marriage. This was a great demonstration of devotion and love towards Mohana. A year later when Johnny and Mohana returned to the island, Mohana’s father came to visit them. He hardly recognized his daughter. She now had long, shining, beautifully combed hair. She had put on some weight, and even her personality had developed some self-assurance and confidence. Johnny Lingo told Mohana’s father that he bought her a silver and pearl inlaid mirror and comb set and had told her every day that she was beautiful. He said that Mohana had always had the beauty inside her; he just helped her discover it. It wasn’t until a few years later that I realized the significance of that movie and the lesson that my father was trying to teach me. We lived in a rural town where work was very hard for my dad to find. Consequently, he had to leave home to work. I was just finishing my hardest year in high school, the sophomore year when my dad took a job in Page, Arizona. I turned sixteen that summer. That was also the summer that I received my â€Å"eight cow bracelet.† Dad was a man who always had a ready smile on his face. For as long as I have known him, he has had crow’s feet at the corner of his eyes from smiling. His hands always seemed big and strong to me, and as he got older, I began to see where I got my physical attributes. He always loved working early in the morning out in our garden when the dew was still on the leaves of the tomatoes and peas. I enjoyed going out there with him. It was a time when we could spend some quality moments together. He would teach me which bugs were not good for the garden as we cleared plump green tomato worms off the tomato plants. He taught me which insects we needed in the garden as we left the spider webs strung between the corn stalks. I learned about rainbows. I learned about life. One particular August morning, Dad took me to sit down at our woodpile. There were always two or three stumps to sit on, and Dad would sit there and watch the garden as he irrigated. He pulled a small bundle wrapped in one of his red â€Å"farmer† handkerchiefs out of his pocket. He simply opened up the cloth to expose a turquoise and silver Indian cuff bracelet. It was slender, no more than a half inch in width. The silver had no engravings on it. It was simple and delicate. Centered across the top of the bracelet were eight round turquoise stones set into the silver. Dad asked me, â€Å"Do you know what this is?† I looked at him and smiled, â€Å"A bracelet?† His ready smile came back at me. â€Å"This is your eight cow bracelet.† When I must have given him one of my most confused looks, he explained how the bracelet would remind me of my worth. I was worth more than anyone else was on the â€Å"island.† I had an inner beauty that was just waiting to come out, and I was important to him. At that time, I couldn’t remember ever loving my father more. A lifetime again later, I still remember that day. I remember the sun beating down on my head, the smell of wet dirt, the sound of our water pump whirring softly as the family inside the house started getting ready for the day. I remember the love in my father’s eyes, and I know that I am an â€Å"eight cow woman.† Questions on Technique 1.
