Essay on Elevating the Power of a Novel through Symbolic...

When reading a piece of literature, a reader often finds many symbolic objects speckled throughout the text. Some of these symbolic objects may be quite obvious to distinguish, while others may be tucked away deep within the text. Whether the symbolism of the object is apparent to the reader or not the author places them in the story to elevate the power of the text. In Truman Capote’s Breakfast at Tiffany’s and Sylvia Plath’s The Bell Jar, there are a plethora of symbolic objects that hold a deeper meaning then what appears on the surface. Capote and Plath two diverse authors, fill their novels with a plethora of dynamic objects, such as a bird cage, a bell jar, a mirror, an unnamed cat and a diamond, in order to develop more powerful†¦show more content†¦Much to the narrator’s surprise during a Christmas celebration Holly tells him: â€Å"Look in the bedroom. There’s a present for you† (Capote 59). The present that Holly has waitin g for the narrator is the bird cage. Despite her dislike for the birdcage and its sense of confinement, Holly presents the narrator with the bird cage under one condition; she doesn’t want the narrator to ever hold an animal captive in it. The narrator returns the birdcage to Holly because it costs too much saying, â€Å"The money! Three hundred and fifty dollars† (59).Since the bird cage is a symbol of confinement for Holly, she gets rid of it out, not wanting it lingering in her apartment. She gets rid of the bird cage due to the fear it gives her of being trapped like she was at Doc’s house in Tulip, Texas. Doc, the husband Holly never talks about, is believed to have made Holly live a tightly confined life in Texas. Her time of confinement in Texas is the reason Holly choose to leave and live a free-spirited life in New York City. Capote has used the bird cage to elevate the power of the novel, by developing the concept that Holly views herself as a type of wild animal that has a fear of commitment and confinement. In comparison to Capote’s idea of a bird cage symbolizing a fear of being held captive, Plath uses a fairly different object to also symbolize how someone can feel imprisoned in his or her own body.

Invisible Social Rules Girl Code-- The Rules of Female...

There is a basic code of behavior that governs female interaction, referred to in the vernacular as â€Å"girl code.† These unspoken rules are largely based on an assumption of trust and respect among the women in a particular social circle and only apply to women who are considered friends or colleagues. â€Å"Girl code† is also firmly rooted in the idea of female competition, particularly in regards to viewing males as potential suitors. A careful analysis of a few of these rules through the three main sociological perspectives will illuminate the underlying themes and meanings in the interactions of women. THE BODY BASHING RULE One of the fundamental rules of â€Å"girl code† concerns body bashing—the act of making negative comments about your own†¦show more content†¦Women generally do not interact with males as they do with other females due to the partial loss of shared understandings concerning the dialog and contact between individuals. For example, there are aspects of a woman’s personality and being that she may be comfortable sharing with other women because of the assumption that they can relate to her, but that she may not be comfortable sharing with men due to the uncertainty surrounding his reaction to or perception of her or the expectation of a negative reaction to her. Functionalism Expanding on the interaction between individuals, the maintenance of a feminine safe space provides a depressurized setting that contributes to feminine solidarity. It allows for the compartmentalization of social relationships, which aids in impression management—the way we present ourselves so as to control others’ perceptions of us. It is generally understood that there is a common ground among women that allows them to let their guard down. That understanding is not present in relations between men and women. Conflict Theory A feminine safe space also serves to separate and isolate the sexes by creating an implicit â€Å"us and them† mentality. This automatically puts men and women at odds with one other, preventing the development of a shared understanding or common ground between them such as that which exists among women. The implicit confidentiality among women breeds a distrust of men thatShow MoreRelatedHow The Changing Status Of Women s Role Within The Household Essay1836 Words   |  8 Pageschanging status of women in Somali society 4 Women as Peace Advocates in the Public Sphere 5 â€Æ' Gender Roles in Somalia Gender roles are socially developed, ascribed and embedded into women and men, and as a result differ across cultures, communities, social classes, nations, ages and different periods of history.

Communication in Interpersonal Relationships Benjamin M. Phelps COM 200 Mrs. Joyce Walther October 4, 2010 Communication in Interpersonal Relationships Today many people still lack the ability to communicate effectively with in interpersonal relationships. We will write a custom essay sample on Interpersonal Communication Com 200 or any similar topic only for you Order Now It is through cooperation and collaboration that effective communication occurs. By analyzing and studying the communication process we can improve our ability to communicate effectively between one another. To have a successful interpersonal relationship one must first interact with others, which is called interpersonal communication (Hybels amp; Weaver, 2007). Recognizing emotions in other is a very important first step to building a relationship. If you can’t feel what someone else is feeling then you can’t connect with them on a personal level and that can hinder your relationship process. Interpersonal communication is important because of the functions it achieves. Whenever we engage in communication with another person, we seek to gain information about them. We also give off information through a wide variety of verbal and non-verbal cues. Verbal communication has huge effects on many aspects of life, including interpersonal relationships. Speaking and telling our needs and wants verbally or non-verbally is a necessity for daily life. Verbal communication is organized by language; non-verbal communication is not. Most of us spend about 75 percent of our waking hours communicating our knowledge, thoughts, and ideas to others (Allis, 2002). However, most of us fail to realize that a great deal of our communication is of a non-verbal form as opposed to the oral and written forms. Non-verbal communication includes facial expressions, eye contact, tone of voice, body posture and motions, and positioning within groups. It may also include the way we wear our clothes or the silence we keep. In person-to-person communications our messages are sent on two levels simultaneously. If the nonverbal cues and the spoken message are incongruous, the flow of communication is hindered. Right or wrong, the receiver of the communication tends to base the intentions of the sender on the non- verbal cues one receives. Before a person makes an attempt to form an interpersonal relationship they must decide what attracts them to that person. There are many factors that make up attraction to others. Physical attraction, perceived gain, similarities, differences, and proximity are some of them (Hybels, 2007). Most people are first attracted to others because of the way they look. Some people might have distinct characteristics that one might be attracted to such as; blues eyes, short hair, or even a small space between their teeth. If a person is not attracted to your appearance they are not likely to come up and carry on a conversation with you. For example, if an individual, who dislikes tattoos, is taking a class and has to choose a partner for a project, but there are only two people left and one of them has tattoos he or she will mostly likely choose the individual without tattoos ,even    if the person with tattoos is a very intelligent individual. There are many cases where we are attracted to someone because of the perceived gain associated them for example, one might become friends with an employee at a restaurant in hope of having discounted meal when they eat there. The similarities and differences are a major factor in determining if the relationship will be right for you. Often we find ourselves attracted to people that share the same beliefs, values, and religion. Most people are also attracted to people who enjoy the same activities as they do. Contrary to the similarities people may also be attracted to the differences. For example, person who doesn’t like making decisions might be attracted to a strong decision maker. Because these characteristics complement each other, they might help strengthen the relationship (Hybels, 2007). Proximity is a valuable factor also when it comes to evaluating the pros and cons of a relationship. Proximity is the close contact that occurs when people share an experience such as at work, school, or play (Hybels, 2007). If a person does not want to have a long distance romantic relationship and their partner moves away to attend college in another state, then it is most likely that the relationship will not last. Moving on to the next steps of forming an interpersonal relationship would be our motives for communicating. We are motivated to form relationships for many different reasons such as, pleasure, affection, inclusion, escape, relaxation, control and health (Hybels, 2007). If an individual is motivated by pleasure he or she might just want someone to go to the movies or discuss politics with. Maybe we might be motivated by affection; many people are looking for someone to give them attention; a â€Å"pat on the back† or a little kiss every now and then. Many marriages end in divorce because of the lack of affection from their partner, but if they could have communicated effectively to each other that they needed more affection the relationship might not have ended. No matter what might motivate us, once we have started developing a relationship we have to decide how much of our selves we want to disclose to the relationship and at what point in the relationship. Self- disclosure is a process in which one person tells another person something he or she would not reveal to just anyone (Hybels, 2007). Self-disclosure is not simply providing information to another person. Instead, scholars define self-disclosure as sharing information with others that they would not normally know or discover (Borchers, 1999). Self-disclosure involves risk and vulnerability on the part of the person sharing the information. Self-disclosure performs many functions. It is also a way of gaining information about another person. We want to be able to predict the thoughts and actions of people we know. Self-disclosure is one way to learn about how another person thinks and feels. Once one person engages in self-disclosure, it is implied that the other person will also disclose personal information. Mutual disclosure deepens trust in the relationships and helps both people understand each other more. You also feel better about yourself and your relationship when the other person accepts what you tell them. While self disclosure can strengthen a relationship it can also damage it. A relationship can be damaged if the person you are pouring your soul out to do not like what they are hearing or if self-disclosure comes too early in a relationship it can be damaged. Thus, while self-disclosure is useful, it can also be damaging to a relationship. There are five different stages that we progress through while developing and strengthening our relationships, these are the â€Å"coming together† stages. No matter what type of relationship it is; romantic, platonic, or same gender relationship each kind still goes through each stages. The first stage is the initiating stage. The initiating stage is characterized by nervousness, caution, a bit of hesitation, and risk of being rejected (Hybels, 2007). Although one might proceed with caution, this stage can be very joyful experience and the outcomes can be great. Most people leave this stage with a new friend. The next stage is the experimenting stage. In this stage people make an effort to seek out common interest and experiences (Hybels, 2007). One might express a love for children and hopes of being a parent one day. This would be an important topic to discuss for a romantic relationship; each person needs to be aware of what the future might hold for them if they continue with the relationship. When experimenting with each other by discussing important topics and seeing the reactions of other, one can make a valid decision based on their knowledge of the other person to continue the relationship to the next stage. The intensifying stage is the third stage that we go through. Self-disclosure becomes more common in the intensifying stage. The relationship becomes less formal and statements are made about the level of commitment each has to the relationship. In this stage individuals might have nick names for one another or â€Å"inside jokes†. A statement about attending a vacation next summer in France is an example of the commitment one might have for the relationship. But while self-disclosure becomes more common and makes the relationship stronger it can also make the participants vulnerable to each other. The integrating stage is the fourth stage. This is the point where personalities are beginning to merge; people are expecting to see them together (Hybels, 2007). The individuals become a pair. They begin to do things together and, importantly, others come to see them as a pair. A shared relational identity also starts to form in this stage. By the end of this stage individuals should know how to communicate and responds with ease and understanding of the other person’s feelings. The final stage of coming together is the bonding stage. At this point, the participants make some sort of commitment that announces their relationship to those around them (Hybels, 2007). Two girls friends might say they are now â€Å"best friends† to announce their comment to their relationship or a couple might announce they are getting married or buying a house together. This stage involves a lot of commitment and dedication to the relationship and to each other. In all of the stages discussed we all have decision to make. We can either progress forward to the next stage, stay in the same stage we are in, move back a stage or exit the relationship all together. No matter what we as individuals choose to do we need to know how to communicate effectively to that next stage and we need to know how to handle conflict or resolve conflict in our relationships. We can do this by conflict resolution, which is negotiating to find a solution to the conflict (Hybels, 2007). Depending on how a conflict is resolved it can produce a positive or negative result. For example if two sisters are fight over a dress to wear on the weekend, they have two choices: one wear the dress and the other one does not, which leaves one sister unhappy (negative outcome) or neither of them wear it, so both are satisfied and neither of them are jealous of the other (positive outcome). It also helps to take a positive approach to conflict resolution, where discussion is considerate and non-confrontational, and the heart of the matter is on issues rather than on individuals. If this is done, then, as long as people listen carefully and explore facts, issues and possible solutions properly, conflict can often be resolved effectively. In short, interpersonal communication is just like any other works of life, it must be practiced and utilized regularly in order to be successful. We must continually analyze and study it in order to improve our ability to communicate effectively in relationships.   That will lead to better relationships which lead to a better life, both personally and professionally.

Violation of Human Rights in The Crucible Essay Example For Students

Violation of Human Rights in The Crucible Essay IB English Exam A2 Question #2 : Violations of the Declaration of Human Rights during the Salem Witch Trials During the Salem witch trials, many violations of todays Universal Declaration of Human Rights occurred. Inclusively, some are still being done today. Upon having a victim under an acusation, many articles were not respected. This is shown in the manner in which past time juries treated the accused. In my opinion, the articles that during those times were violated were article four, five, article six, and seventeen. Article four presents the idea of preventing a cruel or unaccepted treatment towards the victim. It reads the following, no one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment. During the witch trials in Salem, those who were declared guilty, depending on the charges he/she was accused of, the victim might suffer a punishment of being hanged, and one person suffered being crushed under rocks. If the declaration had been functioning during those past moments, it would have occured, most likely, that the victims of the illegal charge of witchcraft, might have been given a life-time jail sentence and not the death-penalty by being hanged or crushed. Another article that had been clearly violated during the Salem witch trials was article five, which states that everyone has the right to recognition everywhere as a person before the law. Many thought of the women accused of practicing witchcraft to be diabolic and inhuman ; in fact, they were thought of human figures of the devil. This would clearly interfere with the judges veredict and it would be almost impossible for the victimis to save themselves from being condemned to death. If these victims of whom most were in their late fifties, had been seen as people who are just like us, they would have been saved from such destiny. Article Six is also a great, and maybe the clearest, example to prove the point of violated human rights. This article says all are equal before the law and entitled without any discrimination to equal protection before the law. All are entitled to protection against any discrimination in violation this Declaration and against any incitement to such discrimination. In the witch trials of Salem, it was perfectly clear that the twenty people that lost their lives were not considered nor treated equally in comparison to the accusers. This occured most obviously because there were no laws that would protect those who had been accused. We can see how unprofessional the system was when the judge told Goody Cloyse to read a passage in the Bible without any mistakes to prove her innocence, and, once she had done so, she was still declared guilty and was sentenced. This article expresses that all people are entitled to protection, but none of the victims of this complot were actually defended nor protected by issues of law and more got saved of the horrible fate others had suffered. Finally, the last article that in my consideration was violated during the Salem Witch Trials is that one referred to as Article 15. This Article says everyone has the right to freedom of opinion and expression ; this right inclues the freedom to hold opinions without interference. If the victims that were accused of witchcraft had really been witches, they should have been respected as should in their freedom of religion, opinion, and expression. Nowadays, witchcraft is accepted as another religions within many that exist in our modern day societies. Clearly, neither the judges nor the accusers nor the jury accepted this freedom and condemned it with the maximum penalty, death. Perhaps there are many more rights in the Declaration of Human Rights that were also violated during these trials, but the onces that to me are most clear, are the ones dictated and explained. These trials had shown no respect to those victims of these horrible accusations and once condemned, these people had no way of escaping death. Nowadays, some violations are still being perpetrated, but at least our society has laws to prevent these violations and our system has become more fair with the years. .u1162384115604d82ed982f1fc3091840 , .u1162384115604d82ed982f1fc3091840 .postImageUrl , .u1162384115604d82ed982f1fc3091840 .centered-text-area { min-height: 80px; position: relative; } .u1162384115604d82ed982f1fc3091840 , .u1162384115604d82ed982f1fc3091840:hover , .u1162384115604d82ed982f1fc3091840:visited , .u1162384115604d82ed982f1fc3091840:active { border:0!important; } .u1162384115604d82ed982f1fc3091840 .clearfix:after { content: ""; display: table; clear: both; } .u1162384115604d82ed982f1fc3091840 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u1162384115604d82ed982f1fc3091840:active , .u1162384115604d82ed982f1fc3091840:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u1162384115604d82ed982f1fc3091840 .centered-text-area { width: 100%; position: relative ; } .u1162384115604d82ed982f1fc3091840 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u1162384115604d82ed982f1fc3091840 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u1162384115604d82ed982f1fc3091840 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u1162384115604d82ed982f1fc3091840:hover .ctaButton { background-color: #34495E!important; } .u1162384115604d82ed982f1fc3091840 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u1162384115604d82ed982f1fc3091840 .u1162384115604d82ed982f1fc3091840-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u1162384115604d82ed982f1fc3091840:after { content: ""; display: block; clear: both; } READ: Juvenile Psychopaths EssayCategory: English .

In their works, the early Netherlandish painters focused on the religious motives and the sacred plots and subjects. These elements became the typical features of the early Netherlandish or Flemish painting. The artists chose the complex forms of diptychs and triptychs in order to depict the religious objects, symbols, and images. The most famous N etherlandish artists belonging to the painting school are Jan van Eyck, Hans Memling, and Gerard David1. Nevertheless, to analyze the particular features of the early Netherlandish religious painting, it is necessary to pay attention to Triptych of Madonna and Child with Angels; Donor and His Patron Saint Peter Martyr; and Saint Jerome and His Lion painted by the anonymous author known as the Master of the Legend of Saint Lucy because of his work in Saint James’ Church in Bruges. The triptych can be discussed as one of the most characteristic representations of Madonna in the early Netherlandish painting which was reflected in the works of the other Netherlandish painters; that is why, the analysis of this work is important to understand the particular features if the early Netherlandish religious painting. The Description and Analysis of the Painting In spite of the fact, the author of Triptych of Madonna and Child with Angels is anonymous, the researchers are inclined to ag ree that the works of the author of the Legend of Saint Lucy in Saint James’ Church in Bruges can be characterized by a lot of features which help distinguish the author’s paintings and speak about the characteristics of the artist’s hand. These characteristics are the usage of intense and contrast colors, strict compositions, and the focus on expressionless faces2. Triptych of Madonna and Child with Angels; Donor and His Patron Saint Peter Martyr; and Saint Jerome and His Lion is an oil painting made on the oak panels. It is possible to admit that the work was painted before 1483. Triptychs were the typical form for the early Netherlandish painters to represent the religious plots in symbolic and sacred paintings3. The triptych depicts Madonna with a child as the central figures and Saints Peter and Jerome as the side figures of the painting. Thus, the idea of the triptych is presented clearly, and the principles of the strict compositions are followed.Advertis ing Looking for research paper on art and design? Let's see if we can help you! Get your first paper with 15% OFF Learn More Each part of the triptych represents two figures. The central figures are Madonna and Christ, the left figures are the donor and Saint Peter Martyr, and right figures are Saint Jerome and the lion. It is rather easy to recognize the figures because of much detail provided. Madonna as the main figure of the triptych is depicted with Christ sitting on the throne. Madonna’s position accentuated the importance of the figure in the triptych. Being depicted in the centre of the panel, Madonna is rounded by two angels portrayed rather symmetrically while standing at the left and right sides in relation to Madonna. Thus, Madonna is dressed in red clothes, and the symbolic dark blue mantle reflects the clothing typical for a lot of Madonna’s images presented in paintings. Christ is depicted naked, and it seems that his right hand is reaching to the flower in the hand of one angel. The other angel is depicted as reading sacred texts. The faces of the figures have the extremely oval shape, and they are rather expressionless. These features are discussed as the characteristic of the artist’s style in painting. The composition of the central panel makes the audience think about the placid religious picture. The donor and Saint Peter are depicted on the left panel of the triptych. The donor is kneeling in prayer and looking at Madonna, and Saint Peter is placing the hand on the donor’s shoulder and is holding the sword in the other hand. The representation of the sword as the certain symbol accentuates the protective role of Saint Peter. The donor and Saint Peter are dressed in black clothes to present their religious roles. It is possible to see the contours of some religious buildings at the background of the left panel. Thus, the artist uses the elements of the two dimensional technique. On the right panel, Saint Jerome is depicted with a lion. Saint Jerome is holding a book in one hand. The lion is snuggling to the saint, and it is holding the saint’s other hand. The background is presented in soft and naturalistic green colors. Saint Jerome is dressed in red clothes which reflect Madonna’s clothes in relation to the color and its intensity.Advertising We will write a custom research paper sample on Early Netherlandish Painting: Triptych of Madonna and Child with Angels; Donor and His Patron Saint Peter Martyr; and Saint Jerome and His Lion by the Master of the Legend of Saint Lucy specifically for you for only $16.05 $11/page Learn More It is possible to note that the artist paid much attention to the colors presented in the triptych. The most vivid colors are characteristic for the dresses of Madonna. Thus, Madonna’s clothing is depicted in deep and intense bold colors. The mantle is dark blue to accentuate Madonna’s integri ty. Saint Jerome is also dressed in deep red clothes. The white clothes are typical for two angels presented on the central panel and for the drapery of Christ. The white color is associated with purity and this symbolic meaning is depicted with the help of the color in the painting. The gold colors are used to depict the throne on which Madonna is sitting. Thus, all the main colors typical for religious paintings are presented in the triptych4. However, it is important to note that the artist is inclined to utilize the intense bold colors, and different tones are used to emphasize the deepness of the basic color. The figures and objects depicted in the triptych are rather realistic in their features, but the lack of balance in the figures’ sizes can be observed. Moreover, the figure of Madonna is accentuated, and it is presented in the centre of the main panel providing the centre for the whole symmetrical composition. The painter focuses on the central figure of Madonna mak ing the other figures be turned to Madonna and Christ while looking at them. The Historical Framework and Relation to the Other Paintings The Master of the Legend of Saint Lucy is discussed as one of the most significant early Netherlandish painters. As the other painters working during the period, the Master of the Legend of Saint Lucy concentrated in his works on the religious plots and provided the depiction of symbols along with the realistic objects to emphasize the connection of the religion and the real everyday life5. The subject of the triptych is the representation of Madonna with Christ accentuating their purity, integrity, and their influential religious role with providing them as the central figures of the triptych in comparison with the figures of saints depicted. The composition with the centralized figure of Madonna was typical for the iconography of the period. Moreover, triptychs were usually used by the early Netherlandish painters to represent the definite relig ious subjects and plots. The image of Madonna was portrayed in many paintings accompanied with different figures6.Advertising Looking for research paper on art and design? Let's see if we can help you! Get your first paper with 15% OFF Learn More The Master of the Legend of Saint Lucy chose the figures of Saint Peter and Saint Jerome to portray them in the triptych. It is important to pay attention to the symbols depicted along with the figures of saints. These symbols could be easily recognized by the audience basing on the religious legends and stories, and they helped determine the personalities of the saints presented. Thus, Saint Peter is depicted with the symbolic sword used to protect Christ, and Saint Jerome is depicted with a lion which is snuggling to the saint to demonstrate his obedience because, according to the legend, Saint Jerome helped the lion remove a thorn from the paw. It is important to note that the question of patronage is closely associated with the work by the Master of the Legend of Saint Lucy. The figures of saints and a donor in the triptych are identified with references to the symbolic objects accompanied these figures7. The tradition to use symbolic objects is characteristic for the early Neth erlandish painters. The idea of the religious triptych with accentuating the central figure is typical for many Netherlandish painters. Referring to the works which were painted earlier than the work by the Master of the Legend of Saint Lucy, it is necessary to pay attention to Hans Memling’s oil triptych made on wood known as Last Judgment (1466-1473). Many researchers agree that Hans Memling’s works influenced the style of the Master of the Legend of Saint Lucy significantly8. Moreover, the elements of the Spanish painting school are also observed in relation to the artist’s works. It is possible to compare the Master of the Legend of Saint Lucy and Hans Memling’s works because the artists used the similar techniques, the colors are compared in relation to their deepness and usage of tones, the depiction of figures is also similar. However, it is also possible to discuss the impact of the triptych painted by the Master of the Legend of Saint Lucy on the works of the other painters belonging to the early Netherlandish school of painting. Thus, Gerard David’s The Virgin among the Virgins (1509) in its composition, figure of Madonna, her face expression, figure of Christ, and clothes is similar to Triptych of Madonna and Child with Angels9. The Master of the Legend of Saint Lucy specialized in painting the religious works, but the discussed triptych took a special position in the artist’s career because it is possible to speak about reflecting the artist’s style and manner of depicting Madonna in the works of the other painters. The triptych is significant because of the subject chosen to depict as the main one and because of the associated elements. Thus, the work was created under the influence of the social tendencies and reflected the importance of the religious motives and sacred subjects in the people’s life. That is why, the presentation of many symbolic objects at the background of rather real thin gs was characteristic for the early Netherlandish painting as the combination of the secular and sacred worlds. The work by the Master of the Legend of Saint Lucy reflects the main tendencies in art influenced by the definite historical conditions typical for the period of 1420-1550. The main patron of the arts at the territories was Philip the Good. He supported the works made according to the naturalistic trends and sacred works accentuating with the help of definite symbols. Moreover, the orientation to both sacred and secular worlds along with the naturalistic details led to the combination of these elements in painting. The patronage of monarchs and their interests in art contributed to the development of the painting school, and the early Netherlandish painters received the opportunity to develop their approaches to presenting the symbolic sacred world along with naturalistic pictures and portraits10. Much attention was paid to details that is why the early Netherlandish paint ers are characterized by meticulousness which is also typical for the work painted by the Master of the Legend of Saint Lucy. Thus, the historical conditions in which the triptych was created can be discussed as rather favorable. Conclusion The triptych painted by the Master of the Legend of Saint Lucy is the example of the traditional early Netherlandish painting with references to the religious motives and subjects used. The role of the Master of the Legend of Saint Lucy in developing the early Netherlandish painting school is significant because the artist not only followed the set standards but he also contributed to the development of the deeper mergence of the sacred and secular elements in the works of the early Netherlandish painters as it is possible to note with references to the later works painted by Gerard David.

Learn How to Delegate Responsibility to Your Employees

Learn How to Delegate Responsibility to Your Employees ]Time is your most precious commodity. No matter how hard you try, you can’t do everything by yourself. Many supervisors avoid delegating responsibilities and the reasons for this vary. Those who have moved up through the ranks of a company may be uncomfortable or simply not used to delegating. Others live by the words â€Å"If you want something done right, do it yourself.† And then there are some who fear delegating may mean being outshined by their employee. Whatever your feelings, as a manager you need to realize that you are not a regular employee, you are a coach. Coaches must understand the importance of teaching, motivating, and taking pride in the performance of their charges. To do this, you must learn how to delegate efficiently and responsibly. Some Things Should Not Be Delegated Never delegate sensitive projects to your employees. If you are in charge of the project because of your expertise, you should complete it yourself. If the project is confidential in any way, be very careful about outsourcing the work. Keep in mind that some jobs need to be done by the person in charge. At the same time, try to avoid delegating only the â€Å"dirty work†. Give your employees something fun and interesting to do once in awhile. Evaluating Employee Abilities There are many things to evaluate before delegating duties. Consider your employees’ skill level, motivation, and dependability. Remember, not every employee is created equal. Certain people will be more efficient than others depending upon the facet in which they thrive. At the same time, try not to typecast your employees. Give them opportunities to broaden their horizons and become more valuable to the team. Matching the proper person to each task can be difficult. Start small and be patient. Providing Clear Instructions When you are assigning unfamiliar duties, be very specific when you explain what you need. By detailing an assignment, you leave no room for confusion and therefore, no room for error. If you have a long list of verbal instructions, type them out. This will give your employee something to refer to when they are performing a task that is unfamiliar to them. If possible, train two people to do the same thing. This way, they can refer to one another for questions, rather than coming to you. It is also essential that your employee has a clear understanding of their authority in each situation. When a decision needs to be made regarding their assignment, should they use their best judgment or should they come to you immediately for clarification? This will be one of your hardest decisions to make because it could mean the difference between success and failure. When in doubt, retain control. Once an employee had proved their capability, give them more responsibility in the decision-making department. Measuring Performance and Controlling Projects Measure the performance of employees and delegated projects. Explain to them how performance will be measured and let the employee know the level of accountability that comes with the task. Clarifying these things beforehand will make everything run much smoother. Large projects may be easier to monitor if they are broken into smaller segments. Spread the assignments throughout your staff and make them report to you after each segment of the project has been finished. Also, get feedback from your employees via meetings and reports. Do this daily, weekly, or monthly. Know what’s going on around you. Staying informed limits the possibility of failure. As a supervisor, you are responsible and accountable for your employees and their work. Coaching Your Staff One of the most important parts of delegation is coaching. When you delegate an assignment, make it clear to them that they can come to you with questions. New tasks can be confusing. Above all, be patient. You should consistently motivate your staff and commend them when they do well. If they complete an assignment, but they don’t do a good job, find out why. Pinpoint what went wrong and take steps to address the issue. On the other hand, when tasks are completed effectively, give your employee the recognition they deserve. Whether it is public recognition or one-on-one, your employee will value being given credit for their work. Doing this not only makes your employee feel good, it will also motivate them to continue their on-the-job success.

Systems Analysis and Design - Case Study Example To identify if the migration succeeded, the primary step is evaluating database values between new and old systems, a test called a parallel type of test. The finishing success is the acceptance test, performing business operations, as well as processes effectively (Satzinger, Jackson & Burd, 2012). The system will develop in every iteration. Integration testing shall be done as part of every iteration. The first system testing will be done in each iteration as a part of the build and smoke testing that is done. Nevertheless, a complete system testing will be conducted as part of a separate system as well as acceptance test activity. Now that integration testing along with build and smoke testing is conducted in each iteration, at the project end, there shall be the definition of a testing iteration to finalize system testing. In this final iteration, the following will take place. System testing, acceptance testing and stress and performance testing (Satzinger, Jackson & Burd, 2012). Q1. Based on Figure 14-6—the XP methodology— divide your use cases into releases and iterations within each release. Develop a project iteration plan that includes the necessary activities at each level (system, release, iteration) for integration testing and acceptance testing. Compare your answer to this question to the project iteration plan you developed for Chapter 9. This system is used by contemplative media agents who rarely are in their offices and the media managers who work frequently in their offices. Therefore, the use cases that mostly apply to media managers will work well on larger computers with screens and keyboards. Some use cases, especially those for view the contemplative practices, will work well for notepads and laptops as well as for smartphone devices (Satzinger, Jackson & Burd, 2012). The entire use cases as well as pages that view practices would be improved if map and location information are provided. This will facilitate both customers and

Relationships in working with young people Essay

Relationships in working with young people - Essay Example Many organisations have been on the forefront in ensuring this is a prevalent occasion as it cements the functionality of the same organisation. For instance, this project was developed to assist the youth in the working environment (The factory sequence 3: Paul’s perspective, 3’00’’). This was to improve their working environment and ensure they are comfortable with what was offered. In making this a reality, the project manager approached working youth and engaged the youth in lengthy talks. This was initiated to get information on what they needed and how they wanted it. Therefore, it openly states that communication was an ideal aspect in getting to know what the youth need in the working environment. There are many issues youth have to deal with, including employment. This is an issue that is affecting a number of families in the society. To save the situation, youths have to look for other avenues of looking for employment. This includes the informal sector, where youths have to start working to support their families. Aggressive and creative youths have to look for employment in supporting their younger siblings. This includes fending for their food, clothing, and getting enough cash to send them to school. In most cases, youths of age 16 and 17 have to look for employment to get more resources. ... In some instances, youths save enough cash and pursue their higher education later in life. This means that all is not lost, especially when youths have networks and can make strong relationships in the informal sector. Building a relationship with the youth does not cost a lot in terms of money. When building a relationship with the youth, you only need to engage in dialogue, talk about issues and make lasting friendship (The factory sequence 2: Kawsar’s perspective, 00’04’’). This is done on a frequent basis where the youth meet, exchange ideas and make decisions. This does not involve use of resources as it is a social activity. However, the issue of resources chips in when they have to make a project from their ideas. In such a case, the only resource that is spent is time. The youth have to spare enough time to relate, talk, dialogue and exchange ideas with other youth. As much as a project is in the offing, the youth will have a stronger bond and rel ationship. In making a strong relationship with the youth in the streets and factories, the project initiators engaged in frequent talks. These lively talks made a concrete bond between the youth and the project initiators. Since they communicated on a frequent basis, they gathered substantial information that could be used in developing the project. The relationship between the youth and the project initiators was enhanced by an agreement point. This is where the project initiators respected the needs of the youth and had to make better ways of giving the youths what they need. In continuous interaction with the youth, the project initiators discovered that the youth had wider perspectives

Introduction Of Engine Block

Introduction Of Engine Block Until recently, cast iron and aluminum alloys have been successfully used to manufacture most diesel and conventional gasoline-powered engine blocks. However, with a greater emphasis on increasing the efficiency of the engine via weight reduction, there is a search for alternative alloys that are lighter than cast iron and aluminum alloys, while retaining the necessary strength to withstand the forces of an engine. In the late 1990s engine blocks made from plastic and other experimental materials were being used in prototype cars with the hope of developing more lightweight, efficient vehicles . Also lately new manufacturing processes have been developed that have brought to light two new alloys suitable for use in an engine block, magnesium alloy AMC-SC1 and compacted graphite cast iron (CGI). Thus this project will cover, the functional requirements of the engine block, the processes used to manufacture the part, and the mechanical properties of the alloys. INTRODUCTION: Todays engines are an integral component of an automobile that are built in a number of configurations and are considerably more complex than early automotive engines. The use of lighter and stronger engineering materials to manufacture various components of the engine has also had an impact allowing engineers to increase the power-to-weight of the engine, and thus the automobile. Since the engine block is also a relatively large component, it constitutes 20-25% of the total weight of an engine. Thus there is much interest in reducing the blocks weight.[Keay, Sue: Diet of Australian metal lightens cars and pollution, Media release, 14 October 2002.] Many early engine blocks were manufactured from cast iron alloys primarily due to its high strength and low cost. But, as engine designs became more complicated, the weight of the engine (and thus the vehicle) had increased. Thus the need to come up with lighter alloys that were as strong as cast irons arose. One such material that was being used as a substitute was aluminum alloys. Together, these two metals were used exclusively to fabricate engine blocks. Lately , however, a new material process has made a magnesium alloy suitable for use in engines. The alloy, called AMC-SC1, weighs less than both cast iron and aluminum alloys and represents new possibilities in engine manufacturing. A new manufacturing process have made compacted graphite cast iron (CGI) a viable alternative to gray cast iron for the manufacture of diesel engine blocks. Like magnesium alloys, this material offers a higher strength and lower weight than gray cast iron. Thus this section will cover materials used to manufacture engine blocks , component discussion, its functional requirements, and the materials used to manufacture the part. The mechanical properties of the individual alloys will be incorporated, along with the manufacturing processes used to fabricate the component. DESCRIPTION OF THE PRODUCT: WHAT IS AN ENGINE BLOCK? : The engine block is vital structure of vehicles which run on internal combustion, providing the powerhouse for the vehicle. The engine block is termed a block because it is usually a solid cast, housing the cylinders and their components inside a cooled and lubricated crankcase .Common components found in an engine include pistons, camshafts, timing chains,rocker arms, and other various parts. When fully stripped of all components, the core of the engine can be seen: the cylinder block. The cylinder block (popularly known as the engine block) is the strongest component of an engine that provides much of the housing for the hundreds of parts found in a modern engine. The block is typically arranged in a V, inline, or horizontally-opposed (also referred to as flat) configuration and the number of cylinders range from either 3 to as much as 16. Figure 1 shows engine blocks with V configuation. opposed configurations. Functional Requirements of a Cylinder Block: Because engine blocks are a critical component of an engine, it must satisfy a number of functional requirements. These requirements include withstanding high cycle fatigue stresses, thermal strains, and aggressive wear conditions over the full life of the engine, housing internal moving parts and fluids, ease of service and maintenance. REQUIRED MATERIAL PROPERTIES: The one-dimensional era of engine design is finished. The current approach considers the loads acting at each point of the engine block. (Vollrath, 2003) In order for an engine block to meet the above functional requirements, the engineering material(s) used to manufacture the the cylinder block material should have adequate strength and rigidity in compression, bending, and torsion. This is necessary to resist the gas pressure loads and also for the components, which convert the reciprocating motion of individual piston into a single rotary motion. The cylinder-block material should (a) be relatively cheap, (b) readily produce castings with good impressions, (c) be easily machined, (d) be rigid and strong enough in both bending and torsion, (e) have good abrasion resistance, (f) have good corrosion resistance, (h) have a high thermal conductivity,(to prevent failure under high temperatures). (i) retain its strength at high operating temperatures, and (J) have a relatively high thermal expansion, low density.(to resist expanding under high operating temperatures) High strength is a particular concern in diesel engines, since compression ratios are normally 17.0:1 or higher compared to about 10.0:1 for conventional engines. , and thermal conductivity . Good machinability and castability of the metal alloy are also important factors in selecting the proper material, as the harder it is to machine the product, the higher the costs of manufacturing. In addition to the previously mentioned properties, the alloys must possess good vibration damping to absorb the vibrations of the moving parts. METALS USED IN THE MANUFACTURE OF THE CYLINDER BLOCKS: Based on the functional requirements of the cylinder block and the material properties required to meet the functional requirements, industries have used cast iron and aluminum alloys to manufacture the blocks. EXISTING MATERIALS: 1)Cast iron alloys are used because of the combination of good mechanical properties, low cost, and availability. 2)Certain aluminum alloys combine the characteristics of iron alloys with low weight, thereby making the material more attractive to manufacturers who are seeking a competitive edge. NEW MATERIALS: 3)Compacted graphite cast iron is lighter and stronger than gray cast iron, making the alloy a more attractive alternative to the latter in the production of cylinder blocks, particularly in diesel engines. 4)Magnesium alloys, which were previously unsuited for use as an engine block material, have the advantage of being the lightest of all the mentioned metals, yet still retains the required strength demanded by a block. 1)GRAY CAST IRON ALLOYS: Gray cast iron alloy have been the dominant metal that was used to manufacture conventional gas-powered engine blocks. Though extensive use of aluminum alloys has minimized the popularity of this material, it still finds wide use in diesel-fueled blocks, where the internal stresses are much higher. The use of cast iron blocks has been wide spread due to its low cost and good formability. Generally types of gray cast iron of pearlite microstructure is used in the manufacturing of engine block. Gray cast iron alloys typically composition: A typical cast iron is a gray cast iron, which contains 2.5-4 wt.% carbon, 1-3 wt.% silicon, 0.2-1.0 wt.% manganese, 0.02-0.25 wt.% sulfur, and 0.02-1.0 wt.% phosphorus [Anyalebechi, P.N.: Essentials of Materials Science Engineering, January 2005, p. 94.]. and the balance (93.6%) iron. The carbon improves lubrication property of graphite, the silicon controls the formation of a laminated structure, called pearlite, which has good wear resistance, and the manganese strengthens and toughens the iron structure. A common aluminium alloy composition is 11.5% silicon, 0.5% manganese, and 0.4% magnesium, with the balance (87.6%) aluminium. The high silicon content in this alloy reduces expansion but improves cast-ability, strength, and abrasion resistance, while the other two elements strengthen the aluminium structure. While this alloy provides a good corrosion resistance, it can absorb only moderate shock loads. Types of cast iron used in engine block: SAE grade G2500- used for small engine blocks. SAE grade G3500-used for heavy and larger diesel engine blocks. Also some ductile iron are also used in manufacturing engine blocks. SAE AMS 5313C: mechanical properties: [alloying: understanding the basics , by joseph R devis.] Grade or class Hardness HB(a) Tensile strength min(b) MPa Yield strength min(b) MPa Elongtion in 50 mm(2in),%(b) Class A 190 max 414 310 15 Gray cast iron has excellent damping capacity, good wear and temperature resistance, is easily machinable, and is inexpensive to produce. However, gray cast irons are relatively weak and are prone to fracture and deformation. Although cast iron meets most of these requirements, it has a low thermal conductivity and is comparatively heavier. Due to these limitations, light aluminium alloys have been used as alternative cylinder-block materials for petrol engines. Cylinder liners are optional with cast-iron blocks; but are more essential with the relatively soft light aluminum alloy blocks, as they cannot directly withstand wear resistance. Because of the lower strength of the aluminum alloys, the blocks are cast with thicker sections and additional support ribs, so that their weight becomes about half of the equivalent cast-iron blocks. Due to these problems, compacted graphite iron has recently begun to compete with gray cast iron as the choice material to produce diesel engine blocks. COMPACTED GRAPHITE CAST IRON: Compacted graphite cast iron (CGI), which was accidentally discovered while trying to produce ductile cast iron, possesses higher tensile strength and elastic modulus than gray cast iron due to the compacted graphite found on the microstructure of CGI. Figure 8 CGI typical microstructure: 5% nodularity, 9% graphite, 265 particles/mm2. 3. CGI a new combination of properties: As shown in Fig. 8, the compacted graphite iron graphite particles appear as individual worm-shaped or vermicular particles. The particles are elongated and randomly oriented as in gray iron; however they are shorter and thicker, and have rounded edges. The compacted graphite morphology inhibits crack initiation and growth and is the source of the improved mechanical properties, as compared to gray iron. Compacted graphite iron invariably includes some nodular (spheroidal) graphite particles. As the nodularity increases, the strength and stiffness also increase, but only at the expense of castability and thermal conductivity (Guesser et all, 2001). It is usual to set a limit of 20% nodularity for CGI specifications. Table 1 shows mechanical properties of CGI, with grades from 300 to 500 MPa. In the case of cylinder blocks and heads, where castability, machinability and heat transfer are all of paramount importance, it is necessary to impose a more narrow specification. A typical specification for a CGI cylinder block or head can be summarised as follows: 1) 0-20% nodularity, for optimal castability, machinability and heat transfer 2) No free flake graphite, flake type graphite (as in grey iron) causes local weakness 3) >90% pearlite, to provide high strength and consistent properties 4) This general specification will result in a minimum-measured tensile strength of 450 MPa in a 25 mm diameter test bar, and will satisfy the ISO 16112 Compacted Graphite Iron standard for Grade GJV 450. The typical mechanical properties for this CGI Grade, in comparison to conventional grey cast iron and aluminium are summarised in Table 1: Mechanical and Physical Propertiesof CGI in comparison to conventional grey cast iron and aluminium at 20 °C Property Units GJV 450 GJL 250 GJL 300 A 390.0 Ultimate Tensile Strength MPa 450 250 300 275 Elastic Modulus GPa 145 105 115 80 Elongation % 1 to 2 0 0 1 Rotating-Bending Fatigue 20 °C) MPa 210 110 125 100 Rotating-Bending Fatigue (225 °C) MPa 205 100 120 35 Thermal Conductivity W/m-K 36 46 39 130 Thermal Expansion ÃŽÂ ¼m-m-K 12 12 12 18 Density g/cc 7.1 7.1 7.1 2.7 Brinnell Hardness BHN 10-3000 215-255 190-225 215-225 110-150 The results allow the comparison between CGI and gray iron. It can be seen the increase on tensile strength, moving from gray iron to CGI. CGI also shows a higher elastic modulus, when compared to gray iron. [- Mechanical properties of gray iron and CGI grades 400-450. 195-230 HB. Samples taken from the castings (Guesser, 2003)]. Figure 10 [Elastic modulus of gray iron and CGI grade 400. 12.0L I6 cylinder block (Guesser, 2003).] The results in Figure 10 were obtained from two sources: test bars and main bearings of a 12.0L cylinder block. The increase in elastic modulus, from 100 GPa for gray iron to 150 GPa for CGI, results in slighter cylinder bore distortion as reported by Tholl et all (1996), therefore reducing oil consumption and emissions. Results of fatigue strength tests can be seen on figure 11, comparing gray iron grade 250 and CGI grade 450, samples from an I6 5.9L diesel cylinder block. The fatigue limit for the gray iron is 62-79 MPa, depending on the carbon content, while for the CGI the fatigue limit is 175 MPa. The raise of fatigue strength allows the designer to reduce the cylinder block weight. As a result of mechanical properties improvements, a design study conducted by AVL Austria (Sorger Holland, 1999) has evaluated downsizing opportunities for a 1.8 L diesel engine cylinder block, converting from gray iron to CGI. The benefits of this conversion included: 1)9% reduction in overall weight of the finished engine 2) 22% reduction in weight of machined cylinder block 3) 15% reduction in overall length of the finished engine 4) 5% reduction in both; height and width of the finished engine Like gray cast iron, compacted graphite cast iron has good damping capacity and thermal conductivity, but its difficulty to machine has limited the wide-scale use of CGI. A new manufacturing process, however, has opened the way for larger applications of CGI. The development of rotary insert tools has increased the life of the tools used to machine the metal, thus allowing manufacturers to use CGI without worrying about purchasing new tools [Georgiou, George: Iron engines may be in your future, Tooling Production, September 2003, Vol. 69, issue 9, p. 26.]. MAGNESIUM ALLOYS: Magnesium alloys have been used in engines before, but not for cylinder blocks. Rather. The main advantage of this alloy is that the material is much lighter than cast iron and aluminum alloys and has the same strength as cast iron and aluminum alloys[Lampman, Steven: Tuning Up the Metals in Auto Engines, Advanced Materials Processes, May 1991, p. 17.][Anonymous, Magnesium alloy resists high temperature in engine blocks, Advanced Materials and Processes, August 2003, vol. 161, issue 8, p. 13.]. Material scientists and engineers were determined to exploit these characteristics of magnesium alloy and use it to fabricate engine blocks. There were a number of magnesium alloys available that met or exceeded the requirements demanded by manufacturers for an engine block, but insufficient material stability at high temperatures hindered their actual use. Following are the two alloys which have been found suitable for mass production of engine blocks. AMC-SC1: In 2003 material scientists and engineers from the Cooperative Research Center for Cast Metals Manufacturing and the Australian Magnesium Corporation presented their discovery of sand-cast AMC-SC1 magnesium alloy [Anonymous, Magnesium alloy resists high temperature in engine blocks, Advanced Materials and Processes, August 2003, vol. 161, issue 8, p. 13.]. This grade of magnesium alloy contains two rare earth elements, lanthanum and cerium, and was heat-treated with T6. This stabilizes the strength of the alloy at high engine operating temperatures, which is a necessary requirement for a cylinder block material [16]. Bettles et al. had performed experiments to determine the yield and creep strengths of AMC-SC1 and their results are shown in Table 3 [Bettles, C. et al., AMC-SC1: A New Magnesium Alloy Suitable for Powertrain Applications, Society of Automotive Engineers, 2003, p. 2.]. From Table 3, the most significant point is that the yield strength of AMC-SC1 essentially stays the same at 177 °C as it does at room temperature. Table 3: Yield and creep strengths of magnesium AMC-SC1 at room temperature, 150 °C, and 177 °C [17]. Room temperature 24 °C 150 °C 177 °C Yield strength, MPa 120 116 117 Creep strength, MPa 120 98 This means that the material is able to tolerate a wide range of operating temperatures without a loss in strength. Other properties of the magnesium alloy 10 include good thermal conductivity, excellent machining and casting qualities, and excellent damping characteristics. To demonstrate the significant weight savings of magnesium alloy over cast iron and aluminum alloy, consider BMWs inline-6 R6 (shown in Figure 4), which replaced the companys M54 aluminum engine. Its cylinder block is made of AMC-SC1 and is said to have decreased the weight of a comparably-built gray cast iron and aluminum alloy block by 57% and 24% [Jost, Kevin: BMW builds better inline six, Automotive Engineering International, January 2005, pp. 20-32.]. So far, BMW is the only company to have used magnesium alloy cylinder blocks in production vehicles. But, with a significant weight advantage over the current alloys used today and negligible increase in cost, other manufacturers will begin to consider the use of AMC-SC1 and possibly other grades of magnesium alloys for engine blocks. Figure 4: BMWs 6-cylinder R6 powerplant uses a magnesium alloy AMC-SC1-fabricated cylinder block [Jost, Kevin: BMW builds better inline six, Automotive Engineering International, January 2005, pp. 20-32.]. PRODUCTION PROCESS: STANDARD CASTING WITH SOME MODIFICATIONS: This alloy can be cast using a standard production process, with some modifications. For a magnesium alloy engine to be economically viable, it is not merely the cost of the alloy that is important. The casting process must also be commercially viable. There are several modifications required if an existing casting line of cast iron or aluminum is to be converted to one producing magnesium parts. These can be summarised as follows: à ¢Ã¢â€š ¬Ã‚ ¢ A new inhibitor in the sand cores to prevent reaction between the melt and the sand. à ¢Ã¢â€š ¬Ã‚ ¢ A redesign of the runner and gating system to ensure adequate filling (magnesium alloys have a low heat content). à ¢Ã¢â€š ¬Ã‚ ¢ Preheating of the core package to 150 °C. à ¢Ã¢â€š ¬Ã‚ ¢ Modifications to the core package design to allow low pressure rather than gravity filling and feeding. AM-HP2: AM-HP2 A High Pressure Diecasting Magnesium Alloy: The AM-HP2 magnesium alloy has similar high-temperature strength to AM-SC1 and has been specially tailored for use in the high pressure diecasting process. Like AM-SC1, the light-weight alloy significantly increases fuel-efficiency, environmental sustainability and vehicle agility and is suitable for the powertrain components of vehicles, such as engines blocks etc. Need for New alloy:AM-HP2 AM-HP2 has been specifically developed as a diecasting alloy for high temperature automotive powertrain applications, such as engine blocks, structural sumps and automatic transmission housings. The alloy is based upon the successful sand casting alloy, AM-SC1, with a modified composition to make it suitable for the high pressure die casting process. Commercial Opportunities AM-HP2 Magnesium Alloy in the Auto industry: High pressure diecasting is a highly productive process for mass production of light alloy components. While the casting integrity of sand casting and low pressure/gravity permanent mould castings is higher than high pressure diecasting, the latter technology is cheaper. Thus, this process is gaining popularity among auto manufacturers for casting of aluminium engine blocks. It is also the common process for powertrain components such as transmission housings. There is a strong demand in the automotive industry for a suitable high pressure diecasting magnesium alloy for high volume powertrain applications. AM-HP2 exhibits good diecastability and the required high temperature mechanical properties for engine components (including engine blocks) and automatic transmission housings. It has similar creep properties to alloy, AM-SC1. Advantages of AM-HP2 Magnesium over Other Alloys: A key advantage of AM-HP2 is that the alloy is more diecastable than competitor high temperature creep resistant magnesium alloys.Thus, the alloy can be more readily cast into complex shapes with fewer rejects and a wider operating window. The alloy also has better high temperature creep strength than its competitors and thus offers considerable advantage to engine designers seeking to obtain maximum performance for lowest weight and cost. current status of AM-HP2 magnesium development: Pilot scale diecasting trials and laboratory testing of mechanical properties have demonstrated the suitability of AM-HP2 for mass produced powertrain components. PRODUCTION PROCESSES: 3.2 Casting Processes There are two methods used to cast engine blocks for all materials: green sand molding or lost foam casting. The latter, pioneered by General Motors for their Saturn vehicles, have[11] become more popular due to its capability to produce near net shape components, provide tight tolerances for critical components, and reduce machine maintenance and cost [19]. Green sand molding, however, is still widely used in industry as material costs are low and most metals can be cast by this method [Luther, Norris: Metalcasting and Molding Processes, [Online], 22 March 2005-last visited, Available: http://www.castingsoruce.com/tech_art_metalcasting.asp.]. 3.2.1 Green Sand Molding: Green sand molding the common method to cast engine blocks. The term green denotes the presence of moisture in the molding sand . Figure demonstrates the pattern used in sand casting. The pattern mounted into the moulding box along with the runner and ingate system ready to produce a mould. [http://www.dmdaustralia.com.au/block1.html] From Figure 2, a combination of silica sand, clay, and water poured in one-half of the block pattern with a wood or metal frame. The mold is then compacted by squeezing or jolting, and the process is repeated for the other half of the mold. A core consisting of hardened sand is used for support. Then, molten cast iron, aluminum, or magnesium alloy is poured into the combined molds and solidifies. Once the latter part has been completed, the molds are removed, and the cylinder block is cleaned and inspected. Heat treatment of the block is then undertaken to improve the mechanical properties of the alloy for suitable use. [7]. 12 LOST FOAM CASTING: THE PROCESS: Figure 6: Graphical description of the last 6 of 7 methods of the lost foam casting method [Anonymous, Aluminum Cylinder Block for General Motors Truck/SUV engines, A Design Study in Aluminum Casings, pp. 1-31.] The lost foam casting process uses a expanded polystyrene replica of the part being cast. 1)The coated replica/pattern is placed in a flask and loose sand is placed around the pattern and shaken into its voids. 2)Molten metal is then poured through a foam sprue, or funnel, into the sand where the hot metal melts and displaces the foam of the pattern. 3)the metal cools in the shape of the part. The basic steps of the lost foam casting process are: 1) Pattern Molding Bead Pre expansion and Conditioning, Tool Preheat, Pattern Molding, Pattern Aging 2)Pattern/Cluster Assembly 3)Pattern Coating and Drying 4)Sand Fill and Compaction Metal Casting and Cooling 5)Shakeout, Clean-up, and Finishing Lost foam casting is a more reliable and efficient casting technique of the manufacture of engine blocks than green sand molding. The technique begins with the use of polystyrene beads placed in preexpanders for wet expansion to control bead size and density to produce four separate block moldings to be glued together to form the final mold [7, 19]. Next, the metal tool is preheated to remove any moisture and then filled with the beads. The tool is then heated via steam and placed in an autoclave, where it is subjected to high pressures in order to create the molds [7]. The tool is removed from the autoclave and immersed in water to finish the moldings. Precise control over the heating and cooling aspect ensures dimensionally accurate, smooth and strong molds [Anonymous, Aluminum Cylinder Block for General Motors Truck/SUV engines, A Design Study in Aluminum Casings, pp. 1-31.]. If the tool was not heated before the beads were injected, the results would be rough finishes in the molds with low-strength sections. If the tool and beads stay heated for an extended period of time, or is not cooled enough, the beads become overfused, which produces surface variations in the moldings. If the tool has been inadequately cooled, the molds will contain variations in dimensions [Anonymous, Aluminum Cylinder Block for General Motors Truck/SUV engines, A Design Study in Aluminum Casings, pp. 1-31.]. Figure 3 shows the final half stages of the lost foam casting method. . From Figure 3, once the individual molds are glued together, the assembly is placed in a vat with water-based ceramic liquid to prevent molten metal from destroying the mold, stiffen the assembly, and provide a smooth finish [Anonymous, Aluminum Cylinder Block for General Motors Truck/SUV engines, A Design Study in Aluminum Casings, pp. 1-31.]. The assembly can also be sprayed with the ceramic liquid, but is a time-consuming process. Next, the coated foam engine block is filled with sand,[13] compacted, and immersed in the molten metal alloy. Once cooled, sand is removed from the metal casting, cleaned, and undergoes heat treatment to increase the mechanical properties of the block. Finally, coolant and oil passages are machined into the block. Advantages over conventional sand casting: Unlike conventional sand casting, the lost foam process allows more complex and detailed passages and other features to be cast directly into the part. The lost foam process: 1) Forms complex internal passages and features without cores. 2) Reduces part mass with near net shape capability. 3) Eliminates parting lines. 4) Reduces machining operations and costs. 5)Provides for tight tolerances in critical areas and features. Lost Foam Casting for Fine Features: The lost foam casting process allows more complex and detailed passages and other features to be cast directly into the cylinder block. 1) In the cylinder block, oil galleries, crank case ventilation channels, oil drain back passages, and coolant passages are cast into the block. 2) These features would otherwise require drilling or external plumbing (with a potential for leaks). 3)Lost Foam castings have tighter dimensional tolerances compared to sand castings, because variations caused by core shift and core variability are eliminated and there is much less tool wear over the production life. The direct result is a significant reduction in machining costs and infrastructure investment and fewer opportunities for errors in machining and assembly. A comparison of green sand casting to lost foam casting shows a number of distinct advantages for lost foam: Property Green Sand Casting Lost Foam Casting Complex Internal Features and Part Consolidation Complexity determined by sand core limitations geometry, strength, and cost. Extensive and complex internal features (as small as 0.20) available in lost foam, based on detail duplication and pattern assembly in foam. Dimensional Tolerances +/- 0.030 is typical depending on part size, complexity, and geometry +/- 0.005-0.010 is typical depending on part size, complexity, and geometry. Surface Finish Capabilities 250-600 microinches typical. Depends on grain fineness of sand. 60-250 microinches typical. Depends on bead size and ceramic coating grain fineness. Feature Accuracy Core movement and shift between mold halves across the parting line limit feature accuracy. No cores or mold halves to shift and degrade feature accuracy Parting Line and Draft Angles Parting lines and draft angles are necessary for molding. No parting lines in the mold and minimal draft on tools. Environmental Costs Sand recovery requires binder removal and time consuming sand clean-up Sand is binder free, so it can be easily and rapidly recovered a

The Beatles :: Essay on The Beatles

The Beatles are even today known as the greatest and most influential act of the rock era. They introduced more innovations into popular music than any other rock band of the 20th century. Moreover, they were among the few artists of any genre that were simultaneously the best at what they did, and the most popular at what they did. They were also the first British rock group to achieve worldwide prominence, launching a British Invasion that made rock truly an international phenomenon. Guitarist and teenage rebel John Lennon got hooked on rock & roll in the mid-'50s, and formed a band, the Quarrymen, at his high school. Around mid-1957, the Quarrymen were joined by another guitarist, Paul McCartney. A bit later they were joined by another guitarist, George Harrison, a friend of McCartney's. As the line up of the Quarrymen grew and depleted, the Quarrymen were eventually reduced to the trio of guitarists: Lennon, McCartney and Harrison. The Quarrymen changed their name to the Silver Beatles in 1960, quickly dropping the "Silver" to become just the Beatles. Lennon's college friend Stuart Sutcliffe joined on bass, but finding a permanent drummer was a problem until Pete Best joined in 1960. Although the Beatles had "artfully combin[ed] the best of American musical influences , the vocal style of black rhythm and blues groups from the 1950s, the primitive excitement of rock 'n' roll, the flair of Elvis, and the slickness of the American "hit parade"" (Assayas, 26) they hadn't fully developed , and some of their early recordings were issued only after the band's rise to fame. Near the end of 1961, the Beatles' exploding local popularity caught the attention of local record store manager Brian Epstein, who was soon managing the band as well. He used his contacts to acquire a January 1, 1962, audition at Decca Records. After weeks of deliberation, Decca turned them down, as did several other British labels. Epstein's perseverance was finally rewarded with an audition for producer George Martin at Parlophone, an EMI subsidiary; Martin signed the Beatles in mid-1962. By this time, Epstein was grooming the band for national success by influencing them to get rid of their leather jackets and throw on a suit and tie.One more major change was kicking Pete Best out of the band. Best was replaced by Ringo Starr. As each of the groups singles sold over a million copies in the U.

Cultural Considerations Essay

This paper will examine and assesses the cultural concerns and influences of today’s societies with mixed cultures and the effect on the criminal justices system. The paper will address how the cultural concerns and influences affect justice and security administration and practice. The paper will show some contemporary methods by the police and security used in societies of mixed cultures. The paper will address how these influences and considerations relate to and affect nondiscrimination practices within the criminal justice system. Finally, the paper will address Sir Robert Peel’s nine principles and how they fit into today’s police departments. The military occupation of numerous countries in the Middle East and Europe has brought police practices into question. The local police forces have been trained by the military in which the rules are different. The free people are suffering abuse at the hands of the police in those countries. In those cases where militant law is present and security is more prevalent, the police appear to work more for the current occupying military than for that country’s government or the people. More than 200 cases of torture have either been investigated or court marshaled by the United States in violation of the United Nations anti-torture body in 2006. This increase in torture may be caused by racial, ethnic, and religious differences in the contemporary War on Terrorism (French &Wailes, 2008). The abuse on that scale does not occur within the United States; however, a problem still exists with the assessment of police and security personnel. These practices are scrutinized by the military, governments, security agencies, and local and foreign police. Of course, these practices question discrimination and profiling. Profiling is one of the major concerns here in the United States. Some confusion exits between profiling and racial profiling. A person cannot be profiled by a police officer based on color, sex, religion, or culture. However, a person can be profiled if he or she matches the description of a suspect. The measures currently used to assess officers are objective and may disclose intimate aspects of the person tested. The standard for recognition in the United States is the Commission on Accreditation for Law Enforcement Agencies (CALEA) that was established in 1979. Psychological testing is in place, however; standards are not set by CALEA, and each agency conducts their own testing (French & Wailes, 2008). In 1973, the National Advisory Commission on Criminal Justice Standards and Goals recommended that every police agency follow a formal selection process that includes a written test of mental ability or aptitude, an oral interview, a psychological examination, and a background investigation. It was believed that introducing greater screening and standardization to the selection process would result in a more qualified police force. International Association of Chiefs of Police (IACP) developed several guidelines for pre-employment psychological evaluations. These recommendations address such issues as validation of testing instruments, compliance with legislation, such as the Americans with Disabilities Act (ADA), using qualified psychologists familiar with the relevant research, and content of the written reports (Cochrane, Tett & Vandercreek, 2008). Compliance with such acts as the ADA indicates the implementation of diversity in the testing process. A few of the most common comprehensive personality tests given to police officers during their psychological testing include the following: Neuroticism, Extraversion, and Openness (NEO) Personality Inventory, Minnesota Multiphasic Personality Inventory–2(MMPI-2), and Inwald Personality Inventory (IPI). Traits from the NEO Personality Inventory–Revised, which was based on the five-factor model of personality, have also shown to be predictive of police performance. The MMPI-2 and the IPI have been shown to be effective in predicting several job criteria for police officers as well (Cochrane, Tett & Vandercreek, 2008). Today’s American policing and justice system is based on English principles and English common law. One such tradition was limited police authority. This gives way to liberties and freedoms and limits governmental authority. Another tradition was the localized police control as opposed to a national, centralized police force as experienced in many other countries. This turned out to be both an advantage and a detriment. The localization resulted in fragmentation and decentralization of law enforcement. The advantage was acquiring little national control (Walker & Katz, 2011, p. 24). Peel believed that prevention of crime could be accomplished without intruding into the lives of citizens so he developed the nine principles of community policing. His first concept was the basic mission of police was to prevent crime and disorder. The prevention of crime makes the job easier of the police. Police presence is deterrence, therefore prevents crime from occurring. This is the basis for today’s community policing concept. The public must also approve of the actions of the police in the performance of their duties. The people must work voluntarily with the police in observance of the laws to maintain public order (History, 2002). The public must comply voluntarily with the laws and work with the police. Most people do what is morally correct; in turn the police also must do what is lawfully correct. The police are directed by the United States Constitution and the Bill of Rights to safeguard every citizen’s right from interference from government. These philosophies are still observed today. If a citizen does not approve of the conduct of the police, a complaint is filed. If the public does not agree with a law, they work to make changes. If the public fails to observe the law, there are consequences, such an arrest or a fine. Another concept concerns the use of physical force to gain compliance. The public is cooperative with the police whereas physical force not need be employed. If compliance is not gained and physical force is required, the force will not be so great as to be considered excessive (History, 2002). The Constitution provides rights to the people and protects them from the police in this area. Laws in most states specifically write out what is considered â€Å"force,† when and how it can be used. Last, the police are specifically trained in the application of force through means of various weapons and hand to hand combat. This force is not to be excessive, not to be used as punishment, or in a punitive manner. The force used is that reasonable force to effect and arrest, to protect oneself or another from death or great bodily harm. The police serve both the public and the law, they shall not show impartiality, but to the law. The officers are also members of the public. Any interest the public has would also be interest to the police (History, 2002). In this case, the officer may come from any background may be either sex or any race. The officer must show fairness to members of other groups and not discriminate against those members or members of his or her own group. The officer shall treat everyone as equally as possible. The police are hired to uphold the law, at the same time serve the public. Peel’s theory indicates, when a conflict arises, the service to the law should outweigh the public service. This concept is contradictory to today’s practices. Policing has become â€Å"customer service†-oriented, where the customer is always right. The officers are members of the public, when they are in an off duty capacity, they are afforded the same rights as any other citizen. However, they should govern themselves as an upstanding citizen because they do represent the law. The final concept indicates the effectiveness of policing is the lack of crime and disorder. This concept is known as preventative policing. In today’s society, the crimes are not occurring where there is a high police presence. So, Peel’s principles are still used to some extent. The demographics have changed since his time. People and crimes have evolved. People’s values have changed, whereas they are tolerant of certain crimes. The attitudes toward police have changed. In a location where there is a strong police presence, fewer crimes occur. This is consistent with Peel’s concept. However, if the demographics of the neighborhood are less desirable, the people of the neighborhood indicate the police are prejudiced and do not want the police in the neighborhood. Thus, more crimes occur in this less protected neighborhood. If fewer police are present, the response time for an officer to an incident is longer because there are fewer officers and more calls. The ratio of officers to calls is higher. In these cases discrimination is blamed for the increased of police presence and the lack of it as well. The affected parties assume they are discriminated against because more police are in their areas, where more crime occurs. However, when the police are not present, they blame the police for the increase in crime because the police are not present. In conclusion, most of Sir Robert Peel’s principles can be applied to the organization of a police department today. In fact, many departments in England still work by his principles. Some need to be altered to accommodate today’s society to be more â€Å"customer† friendly. The United States Constitution and Bill of Rights need to be recognized, as well such as the Due Process Clauses to both the Fifth and Fourteenth Amendments if his principles are applied.
