Managing Change Exercises

Redesign Roles The process of redesigning roles among business organizations actually aim to make it possible for business staffs to gather ways by which they are able to extend their skills, their capabilities of completing their jobs as members of the organization. The major aim is to actually serve the company right through equalizing the ways by which the staffs are given their chance of differentiating their environment with that of the others. This then would naturally hold the employees strongly capable of shifting their capabilities of completing their jobs with the organization. Shifting their responsibilities actually open the employees to new wave of tasks that actually enhance their skills as individuals as well as assets of the organization. The aim of shifting their responsibilities and roles in the organization actually aims to help them get over the effects of work boredom. 2- Redesign Reward System Everyone has the right to have a chance to enjoy company rewards. It is essential however that the required standards for such rewards be shifted every now and then to allow others have a chance to enjoy the benefits of the said rewards according to their capabilities as individual workers of the company. Shifting the different requirements for the said rewards is a certain step up for the organization’s way of motivating their people. 3- Act Consistently with Advocated Action Without the administration’s wise judgment of the situations that they are supposed to deal with, it is undeniable that the decision making process within the organization would weaken thus making it harder for the business company to progress as a group of asset staff members within the industry that they are involved with. Moreover, the lack of advocated action on the part of the administration would cause the entire organization to fail within the plans that they themselves have set to complete. Most likely, failure is the result of the major plans that they are to suspend as part of the organization’s progress. 4- Encourage â€Å"Voluntary Acts of Initiative† Encouragement is one of the key reasons why people stay at the jobs that they are working at. Primarily, people feel that they are special or are worthy of the company if they are able to understand the fact that they are given the right attention by their employers through encouraging them to be their best at doing the tasks that they are particularly appointed to complete. Failure to do so would naturally cause the organization’s failure in terms of boosting its staff’s morale in performing well at their jobs. It is necessary that a company’s administration be able to adjust its priorities so as to be able to set the encouragement that they think is needed by the staff. No matter how diverse the people within the organization maybe, the effective strategies of the administration in posting the plans for encouragement could actually boost the morale not only of the individuals but of the entire organization as well. EXERCISE 12.4 â€Å"Reflection on Your Experience of Change: Profile of Yourself 1. Repeat this list 2. Rate yourself in regard to each action. The actions that have been mentioned within these activities are of high importance to the author as he views hem as primary foundations of organizational success. As for personal evaluation, the application if the two factors of management as mentioned herein has a good rating on the part of the author’s self-evaluation, whereas, the second phase of management which includes the two other factors of management is where the author rates quite lower than the accepted average rating. This is because of the fact that the author might have actually intended to boost the moral of the employees as individuals thus forgetting the fact that they have to be motivated as part of the entire organization’s work force. 3. Which are the actions that you have identified as most in need of attention (those you rated poor or very poor)? Through the personal evaluation that the author of this paper has done, he has primarily observed that the factors on advocated actions and the voluntary acts of initiative are the ones that require immediate action on the part of the organization that the author is currently involved with. This is because of the fact that the people who are working within the organization that he is involved with are not given much attention as they are not given fine options of actually being involved within the plans of the entire group. Hence, as a result, they are less motivated to perform at their best in the job-tasks that they are appointed with as part of the company. Consequently, the author of this paper aims to encourage the organization in actually giving importance to the said factors of business procedures. 4. Where possible, discuss your ratings with others in the group/class. Are any particular actions most commonly nominated as needing attention? What could be done to develop your capacity in this regard? The factor that commonly requires action within the group is that of the Voluntary Acts of Initiative. It has been observed through the evaluation that the said factor of management is less likely given attention to by the administration as the people intend to be directed by the administration than that of actually serving as part of the company in a voluntary manner. The idea is that less people are able to take consideration of their actions as well as to how these acts particularly affect that of the organizations that they are currently working for. The assets and the major foundations of the organization lie stable within the capabilities of the organization’s employees to work well, as well as voluntarily for the sake of their organization’s success. True, with the self-pursuing attitude of the workers as the administration of the organization itself work well with them, the organization could stand tall in progress, thus continuously advancing in terms of prosperous profit gains and performance level upgrade on the part of the employees.

Love is Greater than Hate (Tale of Two Cities)

In Charles Dickens’ novel, A Tale of Two Cities, he illustrates the constant battle between love and hate. This battle is never-ending, but in the novel, I believe that love won, and that love is greater than hate. Love is displayed as love for family and friends, while hate is displayed as hate for the aristocrats and revenge. Lucie, a young girl who never met her father, grows into a strong woman and her love for her family is evident. Her love even saved her father from his despair. Miss Pross has love for Lucie, affectionately called Ladybird, and cares for her and her daughter, little Lucie, with her life.However, there is also hate. Madame Defarge hates the aristocrats, mostly the Evremondes, and will go to any length to see them suffer. Sydney Carton hates everyone and hates life in general. Can love overpower these emotions; will love prove it is greater? In Dickens’ novel, it did. Lucie loves her father, from the day they first meet, it is obvious, and the sent iment is soon shared by her father. After living a life of hatred and despair for 18 years, Lucie brings Doctor Manette love.The first glimpse we see of this love that will save Doctor Manette from himself is when Dickens writes, â€Å"His cold white hair mingled with her radiant hair, which warmed and lighted it as though it were the light of Freedom shining on him. † (Dickens, pg. 50). After being with his daughter for awhile, her love freed him from his sufferings and brought him back to the man he used to be. The love that Lucie was able to give him, gave him the strength he needed to overcome the hatred that held him prisoner inside the Bastille for so long.But even then, there were times when he relapsed into his old habits from prison. However, Lucie was the one who could bring him back from that despair and hatred with her love. As Miss Pross remarks, â€Å"In silence they go walking up and down together, walking up and down together, until her love and company have brought him to himself. † (Dickens, pg. 103). This just goes to prove how strong love is and how it is greater than hate. Doctor Manette went through a great ordeal of pain and suffering during his 18 years of imprisonment.He held a hatred for the Evremondes because they are the ones who put him in prison after he tried to condemn them for their unlawful actions towards the peasants. Doctor Manette writes in his letter, â€Å"Them and their descendents, to the very last of their race, I Alexandre Manette, unhappy prisoner, do this very last night of the year 1767, in my unbearable agony, denounce to the times when all these things shall be answered for, I denounce them to Heaven and to earth. † (Dickens, pg. 342).When he is recalled to life by his daughter Lucie, he forgets these troubles and is able to live a happy life. When Lucie falls in love with Charles Darnay, an Evremonde, Doctor Manette’s old pain, hatred, and suffering arises. We see this illustrated wh en Dickens writes, â€Å"In a very curious look at Darnay: an intent look, deepening into a frown of dislike and distrust, not even unmixed with fear. † (Dickens, pg. 86). However, in chapter 10 of Book 2 entitled, Two Promises, Charles Darnay admits to Doctor Manette that he loves his daughter, Lucie.To this, Doctor Manette exhibits that same dark look, but then turns to Darnay and says, â€Å"If she should ever tell me that you are essential to her perfect happiness, I will give her to you. If there were  ¬Ã¢â‚¬â€œ Charles Darnay, if there were (†¦) – any fancies, any reasons, any apprehensions, anything whatsoever, new or old, against the man she really loved – the direct responsibility thereof not lying on his head – they should all be obliterated for her sake. She is everything to me; more to me than suffering, more to me than wrong (†¦)† (Dickens, pg.142).Even with the history of the Evremondes haunting him every time he looks at Darnay, he is willing to put it all aside for Lucie, because he loves her so strongly. This is an excellent example of how love trumps hate. As an example of the battle of love and hate, one could take Miss Pross as being the personification of love and Madame Defarge as being the personification of hate. Miss Pross has been serving Lucie since she was a young girl and has therefore fallen in love with the young woman.She will do anything for her and treats Lucie as if she were her own daughter. When Lucie has a little girl, Miss Pross cares for her the same way, with ample love and compassion. In one of the scenes in the novel, we are given a glimpse of the love Miss Pross has for Lucie. Dickens writes, â€Å"Smoothing her rich hair with as much pride as she could possible have taken in her own hair if she had been the vainest and handsomest of women. † (Dickens, pg. 104). Madame Defarge, on the other hand, shows no compassion to anyone.She hates all the aristocrats, but mos t of all, the Evremondes. This is for the same reason as Doctor Manette, because the peasants that were abused by the family were her family, and they died at the hands of the Evremondes. She has let this blind hatred lead her life and fuel her anger most of her life. We can see her hatred when she is knotting the coins in the cloth at the wine-shop, â€Å"She tied a knot with flashing eyes, as if it throttled a foe (†¦) as if it were another enemy strangled. † (Dickens, pg. 185, 186).On the day of Charles Darnay’s execution, Madame Defarge goes to find Lucie, Doctor Manette and little Lucie to condemn them to death also. Instead, she finds only Miss Pross. Thus begins the largest battle of love and hate in the novel. Madame Defarge is determined, and armed, but Miss Pross is filled with the strength of love and loyalty. As they fight, Dickens describes Miss Pross’ strength by writing, â€Å"Miss Pross, with the vigorous tenacity of love, always so much st ronger than hate (†¦) held her round the waist, and clung to her with more than the hold of a drowning woman.† (Dickens, pg. 379).After they struggle for a while, Madame Defarge tries to pull her gun out, but it works against her and suddenly Miss Pross is struggling with a dead body. Love has triumphed over hate in the truest sense as hate dies and love lives on. Sydney Carton’s character is introduced as a brilliant man who is bitter and depressed. He tells Darnay the first time they meet, â€Å"I am a disappointed drudge, sir. I care for no man on earth and no man on earth cares for me. † (Dickens, pg. 90).He also admits to himself in that same passage that he hates Darnay, because he has all that Carton will never have, he is the man Carton will never be. Later on in the book, Carton tells Lucie that he loves her, but is glad that she will never love him, and then he says, â€Å"If my career were of that better kind and there were an opportunity or capa city of sacrifice in it, I would embrace any sacrifice for you and those dear to you (†¦) think now and then that there is a man who would give his life, to keep a life you love beside you! † (Dickens, pg.159).This shows that even though Carton has hate for life, he may still show love, but yet none of the two emotions has surpassed the other, until he fulfils his promise to Lucie. When Darnay is sentenced to death by guillotine, Carton sneaks in and takes his place. He sacrifices his life to give Lucie back her husband, to give her back the man that Carton never liked, even hated. The power of love surpassed that of the emotions of hate that Carton has towards Darnay, his love for a woman who will never love him back led his actions.Even at the guillotine, we see the power of love overcoming hate as Carton helps a young seamstress overcome her fears of dying and gave her love before she died. This love was returned to Carton and gave him strength when he went up to die. His face when he died was, â€Å"The peacefullest man’s face ever beheld there. † (Dickens, pg. 385). This further demonstrates that love can, and will always, be greater than hate. Love is by far greater than hate. Love can save, love can heal, and love can grow.Hate is destructive, and that’s its weakness, it has no grasp on people when love is present because love can rebuild all that hate has torn down. In Dickens novel, he gives plenty of proof to show just how powerful love is, and that even if, like Carton, we feel there is no love present, there is, and eventually we will see it. In his novel, we also see that even if hatred has claimed a person for so long, such as Doctor Manette, they can be saved with love.

Effects of Peer Pressure Essay

On their study in examining the nature of peer pressure perceive by adolescent, Brown, B.Bradford, et al (1896),states that 373 students in grades 7-12 were asked to indicate, on a 12-item index, the degree and direction of peer pressures they perceived from friends and acquaintances, and to describe their personal attitudes and behavior in areas corresponding to index items. Analyses revealed that peers were seen as encouraging misconduct less than other types of behavior. Females reported stronger peer pressure than males toward conformity (to peer norms) and social involvement, but the genders did not differ in perceptions of misconduct or pro-adult pressures. Associations between perceived pressures and personal attitudes or behavior were significant but modest, and sometimes were mediated by gender or grade level. And these are the types of peers pressure a person can encounter.And also the possible risk factors they can get in facing these kind of problem According to â€Å"Elizabeth Hartney† Peers are people who are part of the same social group, so the term â€Å"peer pressure† refers to the influence that peers can have on each other. Although peer pressure does not necessarily have to be negative, the term â€Å"pressure† implies that the process influences people to do things that may be resistant to, or might not otherwise choose to do. So usually the term peer pressure refers to socially undesirable behaviors, such as experimentation with alcohol and drug use, rather than socially desirable behaviors, such as academic success, although it could be applied to either, and either could be a positive or a negative experience for the individual. According to â€Å"Kids health line (2011) â€Å"Peers are people who are part of the same social group, so the term â€Å"peer pressure† refers to the influence that peers can have on each other. Although peer pressure does not necessarily have to be negative, the term â€Å"pressure† implies that the process influences people to do things that may be resistant to, or might not otherwise choose to do. So usually the term peer pressure refers to socially undesirable behaviors, such as experimentation with alcohol and drug use, rather than socially desirable behaviors, such as academic success, although it could be applied to either, and either could be a positive or a negative experience for the individual. According to â€Å"Kids help (2008) Negative peer pressure is the type of pressure that you may find yourself wanting to ignore because it makes you feel uncomfortable. Take a second to think about that statement. Can you think of any occasions recently when you have felt uncomfortable around certain people or social settings because you felt pressured to do something to please someone else in order to fit in or not stand out?

Plus, this paper also gives an overview of measuring the performance against standard performance and financial considerations that are necessary to be considered by the financial experts while making decisions regarding expansion of the school in Ecuador. Introduction World has changed its course and education is now given huge importance in almost every part of the world. In today’s era, economies all over the world are confronted with different issues that are economic, political and social in nature. However, in addition to these, education from the past few years has been given tremendous importance and is considered as a mile stone for the nations to achieve their objectives and economic well-being. A society without educated people cannot run smoothly. A political setup cannot be effective until and unless people emp loyed are educated to the highest degree of their potential. Similarly, a country cannot achieve its economic growth and development until and unless the youth of that particular country is educated and contributes something to its country’s economy. ... It is evident from the history that those nations who have considered education as an integral part of their success have always been at the top and remained distinctive among other nations who have not given huge attention to their education policy. Keeping in view the usefulness of education and its effects on economic well-being, this international marketing plan will put forth an idea of introducing a primary school in South America Ecuador. The marketing plan will actually incorporate the expansion of one of the schools of UK into South America Ecuador.

The primary school introduced will actually be an expansion of the existing school of UK named St. Joseph primary school. The reason behind the selection of the Ecuador as a market for a product launch is that Ecuadorians are fond

Decision Making Paper Essay Example | Topics and Well Written Essays - 1500 words

Decision Making Paper - Essay Example As people age, their roles in life become diverse and more choices and decisions have to be made in the light of day-to-day endeavors and pursuits. It is in this regard that this paper is written to present a significant decision-making scenario recently undertaken at Exxon Mobile Security in my capacity as Shift Sergeant for the Security Department. The steps involved in the decision making process would be assessed in terms of its applicability to the scenario at hand. The decision, per se, would be critiqued in terms of its strengths and weaknesses. Other factors, such as the participation of supervisors, co-workers, and/or employees in the decision-making process would be assessed. Finally, an evaluation of any dissonance that possibly emerged from the decision making process would also be identified. Different studies present varying models of a typical decision-making process depending on their perspectives. Some models follow eight steps, others five. For purposes of making intuitive choices, I structurally follow six steps in decision making. The six steps of this natural, intuitive decision-making process, according to Ethics Resource Center (2009) are: â€Å"Step 1: Define the problem; Step 2: Identify available alternative solutions to the problem; Step 3: Evaluate the identified alternatives; Step 4: Make the decision; Step 5: Implement the Decision; and Step 6: Evaluate the decision†. Initially, I was faced with a situation where one of my subordinates, a security personnel, who was scheduled for regular work on a 10:00 PM to 6:00 AM slot, requested for a change in schedule due to emergency reasons. His wife called in early at 8:00 AM and informed the appropriate channels that the security personnel had to undergo immediate surgery for appendectomy.

Fashion industry waste Research Paper Example | Topics and Well Written Essays - 2000 words

Fashion industry waste - Research Paper Example The essay "Fashion industry waste" explores the Fashion Industry and Throw Away Clothes. The job of creating clothes has now been majorly handed over to machines that produce optimum result by the minute. What used to be created in a matter of days has come to minutes. Although this idea has helped to make clothes accessible to people from every type of society, the negative impact is seen when we realize how much clothes may get wasted when we create them in bulks. It’s understandable that when there is demand, there is supply but not every piece of clothing makes its way into wardrobes. Fashion changes by the hour. It doesn’t take much time for the red to become the new black and subsequently, the orange to become the new red. What may be the â€Å"in† piece of clothing may not be in the limelight after a few hours. In such circumstances, large piles of clothes, which may never see the light of the day, may be found in dumpsters in landfill sites. But this cate gory can also include clothes that have been worn a lot or very little due to the aforementioned issue of fashion change. Similarly, people tend to throw out piece of clothing on slightest of issue like for example, if a shirt has lost a button or has caught a stain that can’t be removed, it’s liable to see its way to a dumpster. It is estimated that 14.3 million tons of textiles were produced in 2012, or 5.7 percent of total municipal solid waste (MSW) generation. Many of these were dumped into landfill sites or were incinerated.

Human resource development Essay Example | Topics and Well Written Essays - 1000 words

Human resource development - Essay Example ACC, a Danish company, experimented with a new type of training that was designed to create adult learning associated with the production of a learning organization Initially, the attitudes about the project were quite favourable, however upon launch, participants chosen for the activity found it to be without much merit. This was due to poor communication about the nature of the project, less autonomy and shared decision-making, and the fact that the organisation remained static and would not be changing. This project recommends that there be a new system of training for creating a positive attitude for a learning organisation that include better preliminary communications and also with margin for organisational flexibility. Article overview The article selected for review, â€Å"The learning organization: an undelivered promise†, highlights the activities associated with a year-long training seminar targeting professional employees at a Danish organisation known as Administr ative Case Consideration (ACC). The purpose of the study was to identify the different training methods used to foster a new collaborative learning organisation in which managers could develop new skills as knowledge managers dedicated to promoting learning across the entire staff. The goal was to change employees whilst the organisation, itself, as well as its internal policies and processes, remained static and unchanging. The study’s methodology consisted of professionals being grouped into four work teams, with each portion of training for each team carried out over a three month period. Teams rotated throughout the entire year until the entire organisation had been through the programme. Direct observation by the researcher occurred, therefore validating results significantly as the researcher was able to both participate and interview those involved in the training sessions. Pre- and post-interviews were delivered to the training members to identify whether their attitu des about the training has changed after their three month session was completed. There were four models used in the training, including quality, communications, and generic principles associated with total quality management. The article informs the reader by identifying that such structures are oftentimes socially driven with frustrations caused by limited new skills development. It shows that adult learning is sometimes complex with radical social structures guiding its development and effectiveness, even when social dimensions are not the goal of creating a learning organisation. The advantages of this training were closer interpersonal relationships with colleagues, more so than embracing of the learning organisation concepts. Andragogic approach This study was andragogic in design as it facilitated learning with adult participants. In many ways, it was self-directing, oriented to provide meaningful insight surrounding current problems and tasks associated with ACC, and based o n trust and collaboration. These are necessary to facilitate andragogic learning effectively (Guldem 2009). Since the study did not involve youths, it was not pedagogic in nature and the basis of learning was geared around the elements of adult management and leadership necessary to achieve the goal of promoting a learning organisation. The learning was supposed to be intrinsically motivated, as the preliminary interviews had identified that the majority of participants were initially excited and interested about joining the training structure. However, considerable frustrations occurred in this andragogic effort that will be identified. The model of training used The model used was unique to the environment and activities associated with ACC, however were loosely based on John Dewey’s theory of learning. In this theory, the professionals â€Å"require a preparation to enable them to sense uncertain situations and act upon them by way of inquiry†

A Farewell to Modernism Essay Example | Topics and Well Written Essays - 500 words

A Farewell to Modernism - Essay Example The researcher of this essay "Modernism of Art" aims to explore the work of Jack Ryan in the context of modernism. Castelli is more remembered as one of the core founders of modern art and contributed a lot in nurturing young talents that enhanced modernism of art. Jack Ryan has for years perfected his art in creating unique modern. In looking at Jack Ryan’s work, one could appreciate the effect modernism of art has on the observers. For instance, the picture is one could clearly marvel at his work and appreciate how modernism has taken toll of the market. In today’s world, many artists have started relying on the use of media like the internet to market their art works. Jack Ryan is an excellent example of an artist practicing modernism in art through inclusion of objects or art work associated with the modern age. For instance, the picture provides an iconic feeling of sophistication. He uses random numbers on the upper part of his art work making one to think of what he intended to convey. Furthermore, it results to confusion when he the picture conveys a number of cubic drawings which drawings that resemble speakers. The object provides a feeling of an amorphous creation which no one is able to understand, which is, out of the blue drawing. It is an original work since no one has ever seen such a creation in the normal. Such a drawing creates a deep sense of anxiety and wondering what the artists could have thought or implied to convey while making such an iconic art piece.

Introduction To Modern Technology Media Essay

Introduction To Modern Technology Media Essay Modern technology has made the requirement for information flow to be quick and effective. We have been able to achieve this through the internet; the medium i.e the internet has facilitated each of us, by making the communication cheap and fast. News for U.K is available in the Australia as soon as its on the media, accessible by millions at one time. The growth of the internet is a necessity nowadays. Now internet, where people choose to spend a major part of their day has brought social communities where people can chat, message, share beliefs, extract information, share information about things they are interested in. The internet being the centre of usage for millions of users every day, thus it also appears to be a medium for brands and products to advertise, but this advertisement is different from the advertisement we see otherwise. This advertisement takes into account that the information flow is fast and inspired by people more than the advertising agencies. So let us see how social networking became the part of our lives. The last ten years of the century brought the innovative technology Internet. As predicted by Newman (1991) Internet: Altered the meaning of geographic distance. Allowed the huge increase in the volume of communication. Provided the possibility of increasing the speed of communication. Provided opportunities for interactive communication. Allowed forms of communication that was previously separate to overlap and interconnect. Whereas Grieco and Holmes (1999) (citied in Combe et al, 2003) identifies three powerful features of Internet: Disintermediation or the removal of brokers by allowing direct communication across spatial and sociometric distance; Asynchronicyty of the removal of temporality as a barrier to communications; Oculacy or the ability to communicate messages through images. According to Hermeking (2006) the spread of modern technology, including information and communication technology (ICT), is commonly regarded both as an indicator of the postmodern era of globalization and as the very precondition for that era of intensive worldwide interactions of people and exchanges of goods, services, information, and capital. On the contrary Hoffman (Hoffman et al., 1995) believes that the popularity of the WWW as a commercial medium (in contrast to other networks on the Internet) is due to its ability to facilitate global sharing of information and resources, and its potential to provide an efficient channel for advertising, marketing, and even direct distribution of certain goods and information services. world internet users Sixty five per cent of all UK households had a broadband connection in 2008. Adults under 70 years of age who had a degree or equivalent qualification were most likely to have access to the Internet in their home, at 93 per cent (Office for National Statistics,2009). According to Linda Peters (1998) the Web presents a fundamentally different environment- both as a medium and as a market from traditional communication channels perspective. It creates the Marketspace a virtual realm where products and services exist as digital information and can be delivered through information-based channels (Rayport and Svikola, 1994). Social Networking is a phenomena that has seen a rapid growth over the last few years. If you are not involved in one (or more) of these sites you are probably wondering, so what is this Social Networking thing all about?. Let us go through a general overview of a description of a Social Network A website where people are able to develop networks of friends and associates (whether only ever on line, in real life, or both) and create, share or give information on similar interests, tastes, lifestyles and other information. Also keep in mind that social networking websites are like communities. The Social Networking sites have gained popularity and are on the increase for one simple reason, the ability to share, with others, information about yourself, your interests, your hobbies, your thoughts and your feelings or anything you choose. These can quickly be seen by others in your network and by you through messages, comments, instant messaging applications, photos, games, and group interaction. Facebook one of the most popular social networking sites started as a site for previous College Associates to remain in contact with one another during and after they had finished College. Youtube is another social networking site not just a repository for uploading various types of videos. Some people have found new friendship and romance. People get to know events like fires, storms, and even floods in other countries that have occurred locally in that vicinity, usually even hours before these events are made public by the media. People become involved in many discussions which have given them an opportunity to get to know differing cultures and beliefs One other belief some people have is that it is only Generation Y that use these sites. You will be surprised that many people from many different walks of life in many countries in many age groups use these sites. Some sites are broad category sites like Myspace and Facebook (now). Some are specific to a narrow category, like Small business, the Arts, connecting Families, Blogging, Making Money on the Internet and Dating Services (using a broad and polite term there). Some are popular by type of category they use, where others are popular by region (like UK and Europe, Africa, etc). Social media According to Liu Shrum (2002) new media (Internet), brought new models of interactivity: user-to-user and user-to-message. The interactivity develops a new meaning when it is applied through Web 2.0 platforms and Social media channels as dialogue between consumer and company becomes much more active and interactive. Contemplating about user-to-user interactivity Ha and James (1998) suggested that the more communication in a computer-mediated environment resembles interpersonal communication, the more interactive the communication isà ¢Ã¢â€š ¬-. Defined by Steuer (1992) users-to-message interaction as follows: à ¢Ã¢â€š ¬Ã¢â‚¬ ¢the extent to which users can participate in modifying the form and content of a mediated environment in real timeà ¢Ã¢â€š ¬-. The above figure outlines the E marketing strategy suggested Constantinides (2008) Nielsen Company analyzed and found that the global average time spent for a person on social networking sites is over five each month (February 2010 data), Facebook being the major part of the usage. Social networking is a great option to advertise your business. Social networking does not require large amounts to be invested in, rather its free most of the time, moreover its very simple, easy and quick. There are dozens of websites on the internet where you can sign up within a few minutes and network with millions of people quickly and easily. Social media encourages feedback from everyone who is interested. Social media provokes the user controlled media, empowering the users to drive the communities they are in. Make their comments on products and brands, as they come to them. They can exploit these communities to promote a product and also ruin the reputation of one. Weston (2008) says that, social networking, if approached in the right manner, can build brand awareness, find new customers, help find talent, and help creating a database for market research and analysis. Some businesses find it unnecessary to market themselves on social networking sites, although it is a good way to advertise products/services with knowing what consumers think and want. Social network marketing can be very fruitful for businesses. Social networking media has been thought to be an advertisement source though should be used cleverly to reap of the benefits from it. Thus it is important that the brands committed to using it should use it in the correct way. Zirinsky, 2009 believes online social advertising is all about two way conversations with consumers, not one way broadcastmaking this mistake is far too common and simply makes brands appear out of touch with their audience and reality, and is detrimental to their overall image. Social media keeps an edge over other forms of online communication for its use of enabling content sharing on a network. Content sharing and interaction is defines social media making it different from other means of communication. This means that if brands are going to the get value from social media, they should use it for what it is good in; allowing and helping the sharing of interesting material to create relevant positive hype for the brand or product. Powell, 2009 on the other hand states that Brands need to add value into an online community through enabling the sharing of content, if it cannot do this it has little value, and will be perceived as having little value. For information sharing social media has accelerated the entire process. James in 2009 has said Across networks, a good or bad experience will be shared, potentially on a huge scale. Between 700,000 and 1.3 million blog posts are made daily and, according to Google, a new blog post is being created every second of every day. Most social media services are open to feedback and participation. They encourage voting, comments and the sharing of information. There are rarely any barriers to accessing and making use of content password-protected content is frowned on. Thus a free portal for information sharing, which is effective and fast engages millions of users, now for brands they should be aware how to engage masses they are interested in, because as discussed earlier social networking is probably the fastest way of communication and words positive or negative spread very quickly. Powell, 09 debates Normal social etiquette has crossed over into social media. Social media are communities and there are standards and protocols as to what kind of behavior is acceptable and unacceptable. This statement suggests that the brands should communicate and behave in the social media as to not offend the users of social networking. It is important that whatever information the brands or products are interested in sharing has been uploaded after careful screening and thought process. The strategy for online advertising has to be defined precisely. Thorbjornsen et al. in 2002 affirms that empowering consumers is crucial to online relationships. Rowley in 2007 argues that the concept of customer community leadership has been proposed with the customer being viewed as a partner. Virtual space was a key aspect in amplifying community member experience. Kozinets solicited that retribalized virtual communities of consumption require a newer framework for traditional relationship marketing theory. It is therefore vital at this point to provide a brief overview of tribalism. Cova, 1997 proposes that the potential of tribalism and the linking value has been developed. A tribe is defined as a network of heterogeneous persons in terms of age, sex, income, etc. who are linked by a shared passion or emotion; a tribe is capable of collective action, its members are not simple consumers, they are also advocates; (Cova and Cova 2002: 602). The Internet has only helped to increase the potential of tribalism. E-tribes allow people to gather together in groups based on a huge range of cultural and subcultural interests and social affiliations (Kozinets, 1999: 253). Muniz and OGuinn, 2001 argue that it is crucial to notice that tribal communities are argued to be less explicitly commercial than brand communities. Social Media Web 2.0 Social media and Web 2.0 are two words which are many times used interchangeably in the marketing literature, even though they are not entirely the same. As per the marketing perspective, the Web 2.0 should be apprehended as the recent tool for the marketing communication mix and facilitator and enabler of social media. The Web 2.0 term was introduced by Tim Oà ¢Ã¢â€š ¬Ã… ¸Reilly in 2004, it has originated from talks about social software and the communities surrounding these applications. Tim Oà ¢Ã¢â€š ¬Ã… ¸Reilly said the companies that survived the dotcom boom had something in common; these companies realized that the Web is much more useful for delivering service than being used just as a platform for packaged products (i.e. software). Constantinides and Fountain (2008) on the other hand defined Web 2.0 as follows: à ¢Ã¢â€š ¬Ã¢â‚¬ ¢Web 2.0 is a collection of open-source, interactive and user-controlled online applications expanding the experiences, knowledge and market power o f the users as participants in business and social processes. Web 2.0 applications support the creation of informal users networks facilitating the flow of ideas and knowledge by allowing the efficient generation, dissemination, sharing and editing / refining of informational content . Hoegg believes that Web 2.0 is the philosophy of mutually maximizing collective intelligence and added value for each participant by formalized and dynamic information sharing and creationà ¢Ã¢â€š ¬-. Both of these definitions are exhibits of similar concepts for amplifying the collated intelligence, a community regulated by itself, effects of the network, openness in showing the information creation and sharing process, but the vital aspect here is the consumer. There are not many changes in the Web 2.0 compared to Web 1.0 applications from the technological aspect; value over here is created by the people as they do not just use this software but also play a major role in the creation of these soft wares. Thus as apprehended in modern IT solutions and models, user input is the most vital aspect, can be viewed on a global level with each social networking website. Web 2.0 applications are still considered to be in the development stage, they are categorized according to the purpose and field of the research. Constantinides and Fountain (2008) classify them into 5 broad types according their nature: Blogs: Short for Web logs: online journals, the most known and fastest-growing category of Web 2.0 applications. Blogs are often combined with Podcasts, that is, digital audio or video that can be streamed or downloaded to portable devices. Examples: www.blogtopsites.com , www.blogger.com and several others. Social networks: applications allowing users to build personal websites accessible to other users for exchange of personal content and communication Examples: www.facebook.com , www.myspace.com and others. (Content) Communities: Websites organising and sharing particular types of content. Examples are applications of Video sharing: http://video.google.com, www.youtube.com, http://etsylove.ning.com, Photos sharing: http://www.flickr.com, Social Bookmarking: www.digg.com , http://del.icio.us and Publicly Edited Encyclopedias (Wikis): www. wikipedia.org , http://en.citizendium.org/wiki/Main_Page. Forums/bulletin boards: sites for exchanging ideas and information usually around special interests Examples: www.epinions.com, www.personaldemocracy.com, http://www.python.org. Content aggregators: applications allowing users to fully customise the web content they wish to access. These sites make use of a technique known as Real Simple Syndication or Rich Site Summary (RSS). Examples http://uk.my.yahoo.com/, http://www. google.com/ig, http://www.netvibes.com/. Blogs and blogging Web Logs (knows as Blogs), according to Tredinnick (2006), are arguably the oldest Web 2.0 applications and have been in the web space since mid 1990à ¢Ã¢â€š ¬Ã… ¸s. Constantinides and Fountain (2008) states that it is the most known and fastest-growing category of Web 2.0 applications. Published in Daily Blog Tips, 2008 A Blog is a Web site, usually run by any individual with regular entries of discussions, happening of events, or other content such as graphics or videos where entries are commonly displayed in reverse-chronological order and has permalinks. Antony Mayfield argues (2008), the most important features of the blogs are Linking, Trackbacks, Comments and Subscription (RSS) which allow companies to engage with their stakeholders and facilitates conversations between them. Good blogs are used by people to easily access information and share the viewpoint of things. People from various geographical locations, can log in and write blogs at one place, being able to share knowledge and express them. Blogs help people discover a lot a things that a layman would not be aware of but yet, through a search engine would reach a blogspot where he or she can gain the information they require. The internet guru Seth Godin (2004) remarked that good blogs work when they are based on: candor, urgency, timeliness, pithiness, controversy and utility. Armano (2008) groups these features to 4 Cà ¢Ã¢â€š ¬Ã… ¸s of blogging. Furthermore, Huang in 2007 identified the main techniques for how to manage brand communications according to various blogging motivations. Table 2.2. Bloggersà ¢Ã¢â€š ¬Ã… ¸ motivations. Source: Huang (Huang al., 2007) Social networks Social networking is the fastest growing Web 2.0 application, and this is the main reason for the social media to prosper as quickly as it is powered by effective, fast communication, this media is driven by the users demand. A user prefers to believe in their counterpart rather than any organization. McKinsey defines social networking as systems that allow members of a specific site to learn about other members skills, talents, knowledge or preferences. Pew/Internet believes- A social networking site is an online location where a user can create a profile and build a personal network that connects him or her to other users. Wikipedia states that a social network service focuses on the building and verification of online social networks for communities of people who share interests and activities, or who are interested in exploring the interests and activities of others. It provides various ways for users to interact chat, messaging, email, video, file sharing, blogging and discussion groups The features of social networks present an opportunity to create brand communities and interact with them online. It allows people from all over the world to sign up within a few minutes and access the information available, this has allowed the organizations to be acting in a multinational mode, as they can reach anywhere in the world with the least amount of time taken. Tim Oà ¢Ã¢â€š ¬Ã… ¸Reilly (2005) thinks otherwise and said that Web 2.0 doesnt have a hard boundary, but rather, a gravitational core which could be visualized as a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles, at a varying distance from that core (Appendix 2.4). Therefore it is difficult to classify the Web 2.0 into the precise groupings, because the applications are interrelated and most of the time a few Web 2.0 features works on one platform. The mixture of Web 2.0 applications working under one site are known as Mash-ups. On the contrary according to Mayfield (2008) this combination of two or more pieces of content (or software, or websites) is one of the phenomena in social media that make it at once so exciting, fast-moving and sometimes bewilderingà ¢Ã¢â€š ¬-. But even more vital aspect of Web 2.0 applications is the coherence with the different platforms. Social applications are getting more and more popular on mobile devices (Phones, iPods (via podcasts)). In fact, according to BBC News (2008) one of the reasons the Internet usage on the mobile devices is increasing Web 2.0 applications. According to Drury (2008) social media applications has an ability to bring Head (Professional) and Tail (UGC) content together in all the formats (audio, video , text). As more and more professionally edited websites incorporate social media content some companies (i.e. Joost) are trying to apply Web 2.0 principals (live participation) for even bigger media platforms as TV. These applications are being tested in the Internet TV and in the near future have a good chance to redefine TV experience completely. All these changes open new opportunities for integrated marketing campaigns, where marketers are enabled to reach bigger number of audiences of consumers at all their touch points with mediated world at one-stop shop. Facebook is the most used social networking site that has involved the masses all over the world. Facebook is a social networking site, which provides users with a platform to create a personal profile page, add friends, and send messages, post on their profiles, comment on their status. Kazeniac, 2009 said that since the company was founded in 2004, it has become the top ranked social networking site. According to Facebook Statistics (2009), there are over 300 million current active users (i.e. users that have logged-on in the past 30 days). Facebook users have claimed the site a necessity, along the lines of oxygen, water, and food (Verna, 2009). For many people, visiting Facebook has become an integral part of their daily lives, and has even caused some to have an unhealthy obsession with the site. According to Elizabeth Cohen (2009), a CNN medical correspondent, therapists are seeing more and more Facebook addicts, who become compulsive Facebook users to the point where the site interferes with relationships, jobs, and normal daily life. The site has transformed social communication in the 21st century, with Facebook and other Social networking sites reaching hundreds of millions of people across the globe. Facebook achieves the comptetive edge by adding new features and developments on a continuous basis. Since it is free to create an account, Facebook has to generate its revenue elsewhere, through a venue such as advertising. Companies can utilize Facebooks features to reach their audiences in different ways. Gangadharbatla (2009) states that Social networking sites are changing the way advertisers reach consumers, and that these changes are transforming online advertising all together. There are a variety of ways to use Facebook, and the different features allow creativity and experimentation in advertising. For instance, when users log-on, they are taken to a homepage called a News Feed which highlights recent activities from other users. Each Facebook account also includes a personal profile page, a Wall to write public messages to other users, Facebook-generated applications (photos, events, groups, video, notes, and links), and an inbox to write private messages to other users. T he site also allows users to add optional features called Platform applications to connect in new ways. According to Facebooks statistics (2009), more than 70% of Facebook users utilize Platform applications on a monthly basis. Since these Platforms are optional, it is significant that users are seeking out additional Facebook features and uses for the site. The purpose of Facebook has shifted, as the continued popularity of added features proves that its users are looking for more than just casual networking with friends. A few of the currently popular platform applications include games, fan pages, and gifts. Social-network gaming company Zynga has dominated the site with applications such as FarmVille, Cafà © World, and Mafia Wars. Zynga has over 126 million monthly active users, making it the leading Facebook development platform. The company reported that they currently spend approximately $50 million on Facebook advertising annually, and this figure is expected to increase as the company continues to develop over the years. The games allow Facebook users to purchase virtual products with a credit card, as a means to advance further in the game. Techniques such as these provide Zynga with Facebook-user generated revenues and encourage more advertising and developing on the site. Advertisers can also utilize the option to create a free fan page, where companies and individuals can invite users to become a fan of a product, service, person, company, brand, etc. The page is set up similarly to a profile page, with the option to add status updates, photos, announcements, etc. According to Facebooks statistics (2009), over 10 million users become fans of pages on a daily basis, which provides growing possibilities to reach consumers without any financial risk. The updates on the fan pages are also displayed on the home page news feed of the fans who have joined as fans. There is also a chance to buy birthday gifts, as Facebook has expanded its gift shop to include real gifts alongside virtual ones. This type of online shopping connects cyber space with the real world, so that what happens online does not necessarily stay online. Impact of Social media advertising Castells, 2000 states that it has long been suggested that the western world in particular operates in a network society. The leitmotif of societing the link is more important than the thing is central to tribalism. Crucially, tribalism encourages dialogue in many directions and combinations; Business to Consumer (B2C), Customer to Business (C2B) and Consumer to Consumer (C2C). Drury (2008) suggests that when analyzing social media marketers too often concentrates on the media factor, when social element is the key, because marketing within social media is about building a relationship and conversation with the audience, where the simple message delivery is changed by ongoing exchange of perceptions and ideas between company and the consumer. Haven (2008) argues that social media key elements are not entirely new as features of sharing, connecting, opining, broadcasting and creating has been long in our lives, but there are several characteristics of new technologies and behaviors that set them apart from the past: Reach Historically, audiences for the common person have been limited: a tribe, family, friends, neighbors, or the local community. Todays technologies provide scale and enable anyone to reach a global audience. Accessibility The means of production for most media used to lie in the hands of enterprises with unlimited resources (financial or human). Todays technologies for media creation are available to anyone at little or no cost. Usability The means of production typically required specialized skills and training, both technically and creatively. Todays technologies simplify those processes, or in some cases reinvent them, so anyone can create and operate the means of production. Transparency People, especially Americans, historically kept personal information to themselves and had a general distrust of authority (enterprises, government, etc.). Today, people are willing to share anything about themselves (interests, location, family situations, health condition, etc.) in a public venue, and todays technologies make that both possible and purposeful. Recency When people did have the means of production and distribution in the past (albeit limited), the time lag between communications was typically long (days, weeks, or even months). It was a limitation of the technology or system in which it operated. Todays technologies enable instantaneous responses and dialog where only the participant determines the delay in response. From the results of a research, Ofcom (2008) identified the following fundamental principle of social networking; By extending their social networks, users have the opportunity to communicate with people who share their interests and with people from different countries, cultures and backgrounds (Ofcom,2008). And, Communication with family and friends was found to be the main reason adults used social networking sites (Ofcom, 2008). Next Thing Now (McCann, 2008) said that 74% of social media users use the social media to be able to get in touch with their friends. This fact emphasizes on the fact the social network advertising has to be dealt with care and for the reason of not getting into the line of bad publicity. Glen Urban argued that the customer has much more power then ever before because of the three main reasons: More information. More alternatives. Easy transaction. A study from Delloite Touche USA narrated that 62% of the U.S consumers read consumer generated online reviews and 98% of them find these reviews reliable enough. 80% of these consumers say that these reviews have affected their buying intentions. According to Lockhorn (2007) word of mouth campaigns can take off very quietly through niche communities and can be powerfully persuasive, or conversely result in an astonishing backlash. This perhaps is not good for products, the habitat in which they are pushing to gain an entry is not notably considerate, and even if they do get a break, there is still a lot of competitor brand presence. James, in 2009 states that In a UK study by Jam/MySpace in early 2009, 26% of social media users said they already felt bombarded by too much clutter/advertising. The social media networking is uncommon and challenging and the brands that do not comply to the requirements will have to combat as their competitors reap on the market share. But the ones that can exploit the environment stay to make deeper relationships with the audience, and increase their brand awareness. The information over a social network spreads like a fire. Thus a bad word or a wrong mode of communication will also travel to millions of people at the same time, accessible by millions. The User Generated Content (UGC) can become an influential message of the consumer to the consumer (C2C) about the company and therefore should be carefully monitored. In fact, the content is the new message in social media channels. According to Eikelmann (Eikelmann et al, 2008) the best marketers can do in this environment is to try to engage with the consumers through social media in order influence these messages. Drury (2008) proposes that instead of sending simple messages, marketers should provide the audience with content that would intrigue them and would also be a means to kick off conversations at. Therefore, influence will become a standard measurement in Marketing 2.0 (Dowdell, 2008). As blogger and social media strategist Douma (2008) put it: The age of persuasion is over. Welcome to the age of influence. Give us the people control and we will use it, if you do not give us control you will lose us (Jarvis, 2009). Control now lies with the users, their perceptions, opinions, demands, satisfaction is what matters more. Previously, the powerful; companies, institutions and governments believed they were in control, and they were. Now the internet allows us to speak to the world, to organise ourselves, to find and spread information, to challenge old ways, to retake control (Jarvis, 2009). Companies realize this shift in control when they can stop holding on to what is lost, and start indulging in what is going to attract consumers. Engagement means giving the users content that is interesting and would appeal the masses, also providing them space where they can discuss the content. The control can be handed to the consumer. If the consumer spreads out a positive word for brand, this will create a positive image for it. Social media communities are used by humans, for a brand to prevail, it must use emotions, or undergo the subsequent results. Jarvis 2009 quotes Today, when you lose a customer, you dont lose just that customer, you risk losing that customers friends. And thanks to the internet and blogs and consumer rate and review services, your customers have lots and lots of friends all around the world. According to Powell (2009) The brand is no longer

Laboratorio de Metalurgia Fà ­sica 5.1.3 Practicas en el Laboratorio de Metalurgia Fà ­sica Preparacià ³n Metalografà ­a de Muestras  · OBJETIVO Iniciar al estudiante en la preparacià ³n metalografà ­a de muestras y anà ¡lisis de las mismas.  · INTRODUCCIÓN TEÓRICA: Bajo el nombre de metalografà ­a se engloban toda una serie de tà ©cnicas y conocimientos cientà ­ficos cuyo fin à ºltimo es la observacià ³n tanto macroscà ³pica como microscà ³pica de las caracterà ­sticas estructurales de los metales y aleaciones. La presente prà ¡ctica de laboratorio se basa exclusivamente en la preparacià ³n de muestras (llamadas probetas) para la observacià ³n microscà ³pica de materiales metà ¡licos, a travà ©s del uso del microscopio à ³ptico metalogrà ¡fico (MO).  · La preparacià ³n metalogrà ¡fica Involucra una serie de pasos para obtener una probeta con una superficie perfectamente plana y libre de rayas al observarse bajo el microscopio à ³ptico. Primero se comienza seleccionando una muestra adecuada, cortà ¡ndola para llevarla a un tamaà ±o conveniente y de ser necesario se embute en una resina polimà ©rica o se monta en un sujetador mecà ¡nico para facilitar su manipulacià ³n. Posterior a esto, la superficie debe esmerilarse y lijarse hasta lograr la planaridad y luego pulirse con ayuda de discos rotativos cubiertos de fieltro impregnados de una suspensià ³n abrasiva, para eliminar las marcas del esmerilado. El pulido, provee en la mayorà ­a de los casos una superficie brillante tipo espejo. La observacià ³n al microscopio de muestras no-metà ¡licas, sean materiales cerà ¡micos o materiales compuestos sigue (por lo general) las mismas etapas del proceso de preparacià ³n de muestras metà ¡licas, aunque frecuentemente se requieren de instrumentos de corte y abrasivos de mayor dureza. Las tà ©cnicas y conocimientos para la preparacià ³n de este tipo de muestras se engloban en el tà ©rmino petrografà ­a.  · DESARROLLO EXPERIMENTAL: Materiales y Equipos †¢ Muestras metà ¡licas †¢ Cortadoras de disco. †¢ Esmeril de Cinta. †¢ Papeles de lija. †¢ Pulidoras Rotativas. †¢ Microscopio Óptico. †¢ Dispositivo de captura de imà ¡genes. †¢ Alcohol. †¢ Algodà ³n y recipiente para guardar las probetas  · DESBASTE GRUESO. †¢ Esmerile, en la esmeriladora de cinta, la superficie de la muestra hasta obtener una superficie plana, cuidando de mantener un flujo constante de refrigerante. †¢ Una vez que la superficie a observar està © totalmente plana, lave la muestra con abundante agua. Limpie el equipo. No deje residuos de refrigerante en los alrededores.  · DESBASTE FINO v Comenzando por el papel esmeril de menor nà ºmero, desbaste la muestra movià ©ndola sobre el papel abrasivo en una misma direccià ³n, de manera recà ­proca. La direccià ³n del movimiento debe ser perpendicular a las huellas del desbaste grueso. El proceso culmina al deben desaparecer las huellas del desgaste grueso por la abrasià ³n efectuada, o equivalentemente, cuando toda la superficie de la probeta està © cubierta por rayas paralelas a la direccià ³n de movimiento. v Lave muy bien su muestra con agua y colà ³quela, sobre el siguiente papel de esmeril, de manera tal que las rayas anteriores sean perpendiculares a las nuevas rayas. Repita el paso anterior, hasta que està ©n borradas la totalidad de las rayas generadas en el paso anterior. Puede ir chequeando con regularidad la desaparicià ³n de las rayas observando al microscopio la superficie de la muestra. Asegà ºrese de secar muy bien la muestra antes de colocarla en el microscopio, para ello enjuà ¡guela con alcohol Repita el paso anterior hasta llegar al papel esmeril de menor nà ºmero. v Al finalizar, lave muy bien la probeta, con abundante agua y sus manos con agua y jabà ³n. Limpie con un paà ±o la mesa de lijas, asegà ºrese de no dejar charcos de agua luego de finalizado su trabajo.  · PULIDO Este es uno de los pasos mà ¡s crà ­ticos de la preparacià ³n metalogrà ¡fica, por lo tanto antes de comenzar, lave muy bien con abundante agua el paà ±o que va a utilizar, para evitar la presencia de restos de metal o abrasivos que puedan estropear su proceso de pulido. v Agregue una pequeà ±a cantidad del abrasivo de tamaà ±o de partà ­cula mà ¡s grueso (suspensià ³n de alà ºmina de 1 micrà ³n, generalmente) al paà ±o de pulido y gradà ºe el grifo hasta tener un goteo de agua constante. v Coloque la muestra sostenià ©ndola firmemente sobre el disco rotatorio ejerciendo una presià ³n moderada, para asegurar un pulido parejo y evitar que la probeta sea proyectada por el movimiento del disco. v La probeta debe moverse suavemente desde la periferia hacia el centro del paà ±o y viceversa. Tambià ©n puede girarse en sentido contrario al movimiento del disco. La tà ©cnica y destreza para efectuar el pulido dependerà ¡ en gran parte de la muestra en estudio. v Pida la opinià ³n de su instructor y de ser necesario (la mayorà ­a de las veces lo es) pase a otro paà ±o y continà ºe el pulido con abrasivo de tamaà ±o de partà ­cula mà ¡s fino (suspensià ³n de alà ºmina de 0,3 micrones, generalmente) o con algà ºn otro tipo de abrasivo, esto dependerà ¡ de la muestra que usted està © preparando. v Una vez que su muestra haya alcanzado una superficie plana tipo espejo, là ¡vela con abundante agua, rocà ­ela con alcohol, evitando la presencia de rastro alguno de humedad que pueda crear confusià ³n al momento del anà ¡lisis microscà ³pico. Una vez mà ¡s colabore con el mantenimiento del laboratorio y limpie, con un trapo, todo resto de agua y de suspensià ³n abrasiva que su trabajo haya podido dejar. v Observe su muestra pulida al microscopio, esta observacià ³n, dependiendo de la aleacià ³n, puede ser de significativa importancia a la hora de observar ciertos aspectos microestructurales, tales como ciertas fases e inclusiones, asà ­ como otros defectos propios del material (grietas y porosidades) e inclusive defectos generados en la etapa de pulido (colas de cometa y rayas). PRACTICA NO. 12 Ataque quà ­mico y microscà ³pica à ³ptica.  · OBJETIVOS †¢ Introducir al estudiante en la tà ©cnica del ataque quà ­mico como herramienta para revelar la microestructura de probetas preparadas metalogrà ¡ficamente. †¢ Conocer las partes constituyentes, usos y cuidados del Microscopio Óptico (MO)  · INTRODUCCIÓN TEÓRICA: Sin duda, desde el punto de vista cientà ­fico-tà ©cnico, el aliado mà ¡s importante del ingeniero de materiales es el microscopio, debido a que gracias a à ©l, se puede observar la microestructura, responsable directa del comportamiento mecà ¡nico y fisicoquà ­mico de los materiales. El microscopio utilizado para el anà ¡lisis microestructural de materiales se denomina microscopio à ³ptico metalogrà ¡fico (MO), el cual difiere de los microscopios comunes, en que funciona con luz reflejada sobre la muestra y no con luz transmitida a travà ©s de à ©sta. Luego del pulido, la microestructura del material se ve ocultada por una pequeà ±a capa de metal distorsionado y plà ¡sticamente deformado, que puede ser disuelto a travà ©s del uso de diversas sustancias quà ­micas, denominadas reactivos, las cuales actà ºan generando un proceso de corrosià ³n selectiva que permite, dependiendo del caso, hacer visibles aspectos microestructurales tales como los là ­mites de grano y las diferentes fases que conforman una aleacià ³n.  · PREPARACIÓN PREVIA: Antes de realizar la prà ¡ctica el estudiante debe indagar sobre los siguientes aspectos relacionados con el desarrollo de la misma: v Teorà ­a del ataque quà ­mico y reactivos quà ­micos mà ¡s usuales para el ataque de aleaciones ferrosas y no ferrosas. v Toxicidad y manejo de los reactivos indagados. v Teorà ­a del funcionamiento del microscopio metalogrà ¡fico y sus diferencias con el microscopio biolà ³gico. v Usos, partes constituyentes y cuidados del microscopio metalogrà ¡fico.

Cuà ­dese de evitar el contacto de los reactivos quà ­micos con su piel o con los ojos y utilice guantes de là ¡tex y pinzas para sujetar la probeta mientras la sumerge en los reactivos de ataque. Evite la aspiracià ³n de los gases generados durante la reaccià ³n de ataque y trate en lo posible de trabajar dentro de la campana de gases. †¢ Ataque su muestra con el reactivo que usted haya seleccionado de acuerdo a las caracterà ­sticas de su muestra. Existen varias tà ©cnicas, pero puede hacerlo por inmersià ³n de la superficie pulida en el reactivo, o pasando delicadamente un algodà ³n impregnado del reactivo sobre la superficie. Si tiene alguna duda plantà ©esela al instructor. †¢ Una vez completado el tiempo de ataque, lave cuidadosamente su muestra bajo el chorro de agua, rocà ­ela con alcohol. †¢ Observe la muestra al microscopio y si à ©sta resulta sobreatacada, repita el proceso de desbaste fino (lijado) desde el à ºltimo papel (grano mà ¡s fino) y vuelva a pulir en los paà ±os su muestra. Vuelva a atacar acortando el tiempo del proceso. Si la pieza resulta subatacada, sà ³lo tiene que continuar el ataque por mà ¡s tiempo. †¢ Observe muestra al microscopio bajo supervisià ³n del instructor, con ayuda del encargado del laboratorio y fundamentà ¡ndose en el criterio que debe haber desarrollado a la luz de sus conocimientos y de su preparacià ³n previa a la prà ¡ctica.

Administracià ³n de las Adquisiciones del Proyecto El conjunto[5] de actividades comprendidas en el quehacer de la funcià ³n adquisiciones conforman, normalmente, el segundo bloque de la là ­nea crà ­tica en proyectos complejos. En un sentido amplio, su tarea consiste n abastecer la obra con todos los elementos necesarios (maquinaria, equipos, repuestos, instrumentos, instalaciones, suministros de construccià ³n y servicios), en las condiciones de costo, calidad y oportunidad, requeridas por el proyecto. Una caracterà ­stica sobresaliente de las adquisiciones es su estrecha interrelacià ³n con las demà ¡s funciones, sobre todo en proyectos intensivos en bienes de capital de origen importado, tecnolà ³gicamente complejos, con programacià ³n acelerada (ruta rà ¡pida) o financiamientos condicionados. Las formas en que es posible abordar el abastecimiento de maquinarias, equipos y suministros, son variadas, si se tiene en cuenta el tamaà ±o del proyecto, la existencia y confiabilidad de los servicios de la organizacià ³n perm anente, la complejidad de las adquisiciones, y la modalidad que se defina para los contratos de construccià ³n. Diseà ±o de Formularios y Mecanismos de Control Adquisicià ³n de equipos El laboratorio[6] debe disponer de polà ­tica y procedimiento para la seleccià ³n y adquisicià ³n de los equipos, que incluya: * Especificacià ³n de las caracterà ­sticas necesarias, de acuerdo con los requisitos de tolerancias e incertidumbres. * Seleccià ³n y evaluacià ³n de los proveedores. El laboratorio debe evaluar a los proveedores y mantener un registro de estas evaluaciones. Es recomendable, siempre que sea posible, seleccionar los suministradores que cumplen con la Norma UNE-EN ISO/IEC 17025 o que tienen implantado un sistema de calidad acorde, por ejemplo, con las normas ISO 9000. * Requisitos solicitados al proveedor, tales como: documentacià ³n, certificado de calibracià ³n o verificacià ³n, periodo de garantà ­a, periodo de entrega, etc. En la adquisicià ³n de los equipos nuevos el laboratorio deberà ­a exigirle, a los fabricantes o distribuidores, la disponibilidad del Manual de Instrucciones del equipo en espaà ±ol. * Anà ¡lisis de las ofertas frente a las especificaciones y seleccià ³n de los equipos. Todas las actividades, relacionadas con la compra de los equipos y materiales, convienen documentarlas y archivarlas. Recepcià ³n de equipos Cuando el laboratorio recibe el equipo o material debe constatar, en primer lugar, que: * Se corresponde con las caracterà ­sticas y especificaciones del pedido o solicitud de adquisicià ³n, * Va acompaà ±ado de la documentacià ³n adecuada y completa (por ejemplo los certificados de calibracià ³n o conformidad, si son necesarios). * El laboratorio debe tener establecido un procedimiento que * Asegure que los equipos recibidos no sean utilizados o puestos en * servicio hasta que: * Se haya comprobado que no han sufrido ningà ºn daà ±o y funcionan * correctamente, * Hayan sido calibrados o verificados, cuando se considere necesario, * De que cumplen las especificaciones requeridas, debiendo mantenerse un registro de las medidas adoptadas para comprobarlo. Los equipos recibidos, cuando ya està ©n disponibles o instalados para realizar la funcià ³n para la cual han sido adquiridos, deben darse de alta, codificarse y etiquetarse, y ser incluidos en el inventario de los equipos disponibles del laboratorio. Inventario y codificacià ³n de equipos El inventario o listado (o base de datos) de los equipos disponibles debe incluir, como mà ­nimo, los equipos utilizados para realizar ensayos y/o calibraciones que tengan una relacià ³n directa con los resultados, asà ­ como aquellos equipos auxiliares que requieren de algà ºn tipo de control, mantenimiento, verificacià ³n o calibracià ³n.

El laboratorio debe mantener actualizado el inventario de los equipos disponibles, para ello serà ¡ necesario establecer un procedimiento del control y/o comunicacià ³n (por ejemplo, mediante impresos) de las altas, bajas o traslado

Star Wars as Church History Essay -- Exploratory Essays Research Paper

Star Wars as Church History Koenrad Kuiper, writing in the Journal of Popular Culture in the mid 1980s suggests that "[the] Star Wars trilogy creates and recreates imperial myths which serve to sustain imperial culture" (77). He goes on to contend that the Empire of George Lucas’s long ago and far away world recreate these myths for us now as, essentially, a form of social control. Since Kuiper was writing, however, we have been graced with the first in the Star Wars series, The Phantom Menace. The Phantom Menace has opened to tepid reviews and the expected box-office success. Its staying-power has been perhaps a bit disappointing for all at Lucasfilm, but the film has definitely made a cultural impact. Interesting in light of Kuiper’s thesis is that this latest addition to the Star Wars mythology concerns itself with two beginnings: the beginning of the evil Empire of the other three movies, and the beginning of Anakin Skywalker, father to Luke Skywalker and the future Darth Vader. The genesis of both the Empire and Darth Vader in one film is more than coincidence. Rather than Star Wars sustaining an imperial myth, the new film argues for an interpretation that the series, taken as a whole, represents an intricate commentary on the history of Christianity, from its pure beginnings to its ultimate corruption as a quasi-political entity controlling much of Europe. The first and most striking suggestion of this is the fact that Anakin Skywalker’s is a virgin birth. When Qui Gon Jinn, the Jedi master who trains Obi-Wan Kenobi, asks Anakin’s mother who the young prodigy’s father is, she responds: "There is no father." Young Skywalker is later described by Jinn as a "virgence": a virgin birth. The conclusion that ... ...ica: is there reason to believe that the Religious Right will become that new Empire? Will the new war for liberation be right now in a galaxy quite close to home? Addendum It has been brought to my attention by many an astute reader that Darth Maul should more accurately symbolize King Herod. They are correct, of course--an oversight I should've caught. I appreciate the input, and should take the opportunity to note that the Darth Maul/Herod connection still works symbolically, representing the pathway toward an institutionalized and therefore corrupt Christianity.

Gay Men Should Be Allowed To Donate Blood :: essays research papers

â€Å"A man who has had sex with another man within the last five years, whether oral or anal sex, with or without a condom or other form of protection, is not permitted to donate blood and must please not do so.† This was the statement issued last Thursday by a spokesman from the South African National Blood Service (SANBS). This statement had caused a huge dispute between the SANBS and the Gay and Lesbian Alliance (GLA) Every newspaper has headline after headline about this new topic, every news update on all radio stations, every news program on the television, everybody is talking about this latest disruption in our some-what peaceful lives. The GLA states that on Friday, the day after the statement was made, they donated gay blood, some newspapers claim that 120 units were given, another says over 600 units were donated, all the stories are very conflicting, which one, if any, are we to believe? A big question everyone is asking is that if they did donate gay blood, why did they if they were clearly asked not to, and when they did, it means they lied on the forms about their sexual activities. What good is this going to do anyone one may ask, but if you were in that situation, would you not do something about it to? If they suddenly decided that any white female is forbidden to donate blood, no matter what your HIV status is, would you not retaliate and cause a rebel? This causes us to think, (for once), what the gay men did was wrong by donating their blood, but we cannot point fingers and judge them if we would have done the same. What the SANBS is totally wrong, discrimination of any kind is against the law and yet they are blatantly doing it in front of the whole country, and world. Way back when HIV and AIDS was first discovered, the gay men were the only ones that seemed to be infected with this disease, so at that time it was a reasonable rule to ban them from donating. But now we are in 2006 and every single gender, race, religion and group has been infected with HIV so to only ban gay men is unacceptable.
