Role of Vision at Mentor Graphics - Case Study Example However, later on it had to be changed because it was no longer effective in motivating its employees and growth problems began to emerge. When the company used the vision â€Å"Six Boxes†, it somehow weakened the company because when one of the businesses failed, the company did not have the option of closing it down. If they do so, then the â€Å"Six Boxes† vision will no longer be applicable because there will only be â€Å"Five Boxes†. This vision weakened the company because it prevented management from making the appropriate financial decisions. 3. Identify three key reasons that the vision failed at Mentor Graphics. The first reason why the vision failed at Mentor Graphics is that some of the visions that they developed were too vague. In the case of the vision â€Å"10X Imperative†, the customers did not understand it; most probably even the employees did not know what it meant. The vision is blurred and did not present a clear picture of what the company will be in the future. The second reason why the vision failed is that it is too unrealistic. The vision â€Å"Six Boxes† combined the goals of the six different businesses of Mentor, so much so that when one of the businesses failed, they could not even shut it down. The expectation was that all six businesses will be profitable which was very unrealistic and hard to achieve. The vision at Mentor also failed because it was â€Å"too disconnected from the present† (Palmer, Dunford, & Akin, 2009). Their vision in 1989, â€Å"Changing the World Designs Together† was described by Mentor’s President Gerard Langeler as having little to do with the actual businesses of the company. 4. Discuss issues of vision content, context, and process in how vision was introduced and changed at the company. The initial vision of Mentor is â€Å"Build Something That People Will Buy†. However, this vision had to be changed to be more competitive. Eventually, Me ntor’s vision progressed from being concrete in â€Å"Beat Daisy† to becoming too abstract as â€Å"10X Imperative†. The â€Å"Beat Daisy† vision was practical and answered the needs of the firm at that time. The content and context was well understood by the employees; thus, it was easy to achieve. It was very precise and clear; therefore, it served as a guideline for all employees. In â€Å"Changing the World Designs Together†, the company transformed its vision to become too idealistic rather than making it tangible and realistic. The development of the visions of Mentor depended on the effect it had on the company. If it was not effective in driving the company towards its goals, then the vision was changed. If it was no longer applicable in the current position of the firm, then the vision was changed too. After â€Å"Beat Daisy† most of the visions formulated by Mentor were inspirational though quite ambitious. In the end, Mentor had t o revert back to its original vision which is â€Å"To Build Things People Will Buy†. Langeler realized that this was the more pragmatic vision for the company which was attuned with the core business of the firm and would help them make sound business decisions. 5. Discuss whether or not the vision helped or hindered change at Mentor Graphics There were instances when vision helped the company like when their vision was â€Å"Beat Daisy†. â€Å"Six Boxes† on the other hand hindered change at Mentor because even if they wanted to close down one of the six businesses

Jesus and Mary Essay Example for Free

Jesus and Mary Essay During the last forty years, there has been an increased desire between Catholics and other Christians to discuss the theological positions that have separated us. The Catholic Church’s teachings on Mary have been a crucial element in the discussions that have taken place. There are many hopeful signs of mutual understanding, including a new appreciation for the Scriptural and Patristic presentations of Mary, as well as the writings, homilies and hymns of the Reformers on Mary. There is a better understanding of what the Catholic Church actually teaches about Mary as well as a better appreciation by Catholics of the theological questions that are raised by other Christians regarding Mary. In this environment, scholars from different traditions have reflected upon Mary’s role as a collaborator of God in salvation history as well as her role in the Communion of Saints. One very significant effort has been that of four Lutheran, four non-Lutheran Protestants and four Catholic Biblical Scholars, which produced the book, Mary in the New Testament, (New York: Paulist, 1978). Other noteworthy ecumenical works on Mary have been: Mary for All Christians by the Anglican theologian, John Macquarrie (1990); Mary through the Centuries, lectures of the noted scholar Jaroslav Pelikan, at Yale University (1996); Mary is for Everyone, papers given at four International Congresses of the Ecumenical Society of the Blessed Virgin Mary (1997); and Blessed One, Protestant Perspectives on Mary, edited by Beverly Roberts Gaventa and Cynthia L. Rigby. In reexamining the writings of the original Reformers, scholars have uncovered more sympathy among the Reformers regarding Mary than succeeding generations may have had, as the divisions hardened between what was Catholic and what was Protestant. Catholics and Protestants might be surprised to learn of Martin Luther’s reverence for Mary, as can be seen in his Commentary on the Magnificat, written in 1521. Between 1983 and 1990, Catholics and Lutheran theologians met to discuss the issues related to intercession, the saints and Mary. The summary of these discussions was published inThe One Mediator, the Saints, and Mary: Lutherans and Catholics in Dialogue VII (1992); Since 1937, Protestant pastors and Catholic priests from France and Switzerland have conducted an ongoing dialogue on ecumenical issues. Initially, they first met at the Cistercian abbey of Notre Dame des Dombes, twenty miles north of Lyons, from which came the name of the group. Presently the group consists of twenty Lutheran or Reformed pastors and twenty Catholic priests. They are a private association, which meets yearly. Over the years, they have issued a number of documents on various theological issues. Between 1991 and 1997, they reflected on Mary’s role in salvation. The English edition of their reflections, Mary in the Plan of God and in the Communion of Saints, was printed in 2002. On February 2, 2004, a document was signed by the members of the Anglican-Roman Catholic International Commission (ARCIC), entitled Mary: Grace and Hope in Christ as a statement of the commission which was then submitted to the Pontifical Commission for Promoting Christian Unity and to the Archbishop of Canterbury and the Anglican Consultative Council for further study and evaluation. The document was issued on May 12, 2005, to be used for further study by the churches. It is available on the Vatican website (www.vatican.va) through the Pontifical Council for promoting Christian Unity. While much progress has been made, the efforts at dialogue need to continue. Pope John Paul II, in his Encyclical, Ut Unum Sint, has included the Church’s beliefs about Mary among the five areas where fuller study is needed before there can be consensus in faith.[1] Two of the other areas, which the Pope identifies as principle issues, also relate to Marian dogma: the relationship between Scripture and tradition as well as the role of the Magisterium in teaching and safeguarding the faith.[2] We may ask what we intend to achieve by ecumenism. Is it negotiation by which each group agrees to give up something for the good of accommodating each other? Although some people may assume that this might be the process of ecumenism, the better approach is to strive to seek God’s truth together, wanting to have â€Å"the mind of Christ.† Christian unity will come through humbly seeking the unity that already is in God.[3] Christians who accept the truths of the Trinity and Incarnation must recognize that the Eternal Word was united with human nature in Mary. Mary was the location of the union of the divine and human in the one Person, Jesus. Underlying theological issues related to Marian beliefs: The concerns of non-Catholic Christians about Mary are not related simply to the person of Mary in herself but are related to other fundamental theological truths that served as the basis for the break at the time of the Reformation. Just as there were differences among the reformers there also are differences in the theologies of the various Protestant denominations. There are several key theological concerns which enter into the discussion of Mary. Luther’s approach to the â€Å"Justification† of Mary: Luther views Mary from the perspective of his theological principles by which the human person can never be said to possess any virtuous quality other than faith in the saving power of Jesus. Luther’s teachings on Mary are part of his understanding of the role of the saints in general for him, in which the saints and Mary are examples of what God can do with weak humanity. Luther explains his understanding of Mary within his theology of justification, emphasizing grace: â€Å"Mary also freely ascribes all to Gods grace, not to her merit. For though she was without sin, yet that grace was far too great for her to deserve it in any way. How could a creature deserve to become the Mother of God?†[4] It is noteworthy that Luther speaks of her as being â€Å"without sin.† Luther rejects the notion of merit since he emphasizes that our justification is completely the work of grace. He criticizes Catholic veneration of her as exalting her and so lowering the power of grace. He stresses that Mary does not want us to make an idol of her, stressing her merit, or looking for good things from her but to honor God and have confidence in His grace. [5] The Lutherans in the Lutheran-Catholic Dialogue questioned the practice of attributing virtues other than faith to holy persons based on their conviction that faith alone justifies and that Christ alone makes a person holy: â€Å"In Luthers exposition of the Magnificat, he exalts Mary because she faces her situation by faith alone. An attempt to use Mary or another Christian to extol any other virtue than faith raises the question of undermining living only by faith in Christ.†[6] Luther wrote: â€Å"I say Mary does not desire to be an idol; she does nothing, God does all.†[7] Luthers caution that our attention on Mary should not end with her but be directed to having more confidence in Gods grace may also be understood in a Catholic position. However, Catholics also ascribe all good to God, yet there is a difference in that we believe that God’s grace really changes us and enables to be cooperators with Him in doing good, always relying on His grace. The Catholic position on the way that grace works in our lives was brought out by the Council of Trent: â€Å"Justification consists not only in the forgiveness of sins but also in the sanctification and renewal of the inward being by a willing acceptance of the grace and gifts.† [8] The Council states that while God’s grace initiates and supports any good action, the person can either accept or refuse grace. [9] In 1998, Lutheran and Catholic leaders signed a Joint Declaration on the Doctrine of Justification seeking a greater convergence on the issues of justification. In the Lutheran tradition, God’s initiative is emphasized in justifying us while our response is that of our human freedom moved by grace.[10] If  the acceptance of justification is the first phase, a second phase follows, which is the carrying out of salvation.[11] Luther’s reflection on Mary’s purification in the temple is used by the Dombes Group to locate Mary’s good actions within the experience of being already ‘justified.’ Luther wrote: She was purified†¦although she was not bound by that law and did not need to be purified†¦. She was not justified by this work, but being righteous she did it freely and willingly. So also our works should be done, not that we may be justified by them, since, being justified beforehand by faith, we ought to so all things freely and joyfully for the sake of others.†[12] The Dombes Group seems willing to recognize Mary’s ‘cooperation,’ if it is seen within the perspective of justification by faith. It was because Mary had been justified by grace alone and in faith, that she could be associated with God’s work in Christ. Her ‘cooperation’ was unique in regard to the nature of what she did, for she was the mother of Jesus and raised him. She cooperated in the unique and universal event of salvation. But from the point of view of structure of her status, her ‘cooperation’ was not different from that of every person justified by grace. It was entirely the fruit of the grace of God.[13] As Catholics, we would emphasize both the grace of God in a good action as well as human freedom acting as it is aided by grace. Our cooperation is never separate from God’s help. Issue of human cooperation with God: Karl Barth, from the Reformed or Calvinist perspective, identifies the Catholic teachings on Mary as the prime example of Catholic principle on which â€Å"all their important positions are to be regarded and by which they stand and fall.† Reformed theology emphasizes the principle, sola gratia. According to  Barth, the Catholic teaching on Mary exalts human cooperation: In the doctrine and worship of Mary there is disclosed the one heresy of the Roman Catholic Church which explains all the rest. The mother of God of Roman Catholic Marian dogma is quite simply the principle, type, and essence of the human creature co-operating servantlike (ministerialiter) in its own redemption on the basis of prevenient grace, and to that extent the principle, type and essence of the Church. [14] Barth has accurately noted the relationship Catholics affirm in comparing Mary and the Church, since both the Church and Mary demonstrate creaturely co-operation with grace. He criticizes these Catholic positions on â€Å"creaturely co-operation† which is also related to the role of the church in cooperating with God: Not only does it need Christ, but in all seriousness Christ also needs it. As Mary inevitably co-operates in mans redemption as an intercessory power so does the Church in consummating the sacraments. the Church of the man who co-operates with grace on the basis of grace.[15] In fact, Barth has very accurately identified a fundamental Catholic principle that we cooperate with God. Barth objects to the notion not only of cooperation in good works but also of merit. Actually, the Catholic position is nuanced, taking human cooperation seriously enough to consider that our works are meritorious. Nevertheless, human cooperation has to be seen within the context of the Church’s teachings on the importance of grace in every good work, as Thomas Aquinas explains: â€Å"Man obtains from God as a reward of his operation, what God gave him the power of operation for†[16] John Macquarrie, an Anglican theologian, questions Barths objections by noting that even though ultimately salvation is the work of God, the human person is not a puppet or clay to be molded. As Macquarrie points out, the Marian teaching on the Immaculate Conception, is a clear illustration of salvation as a work of God’s grace since the one being conceived can only receive. Macquarrie points out that during her life Mary had the freedom to respond or not respond to God’s grace: Now it is the human consent and co-operation with God in the work of salvation that come to expression in the career of Mary. Not for a moment can one deny (or would one want to deny) that salvation is from God and is a work of grace, but God does not force His gifts upon us and we can become His covenant partners only if we give our glad and willing assent. [17] As Catholics, we believe, that a woman was preserved from sin by grace, and responded by faith and obedience aided by grace in co-operating in the birth and upbringing of the Son of God. She was made holy by grace but she also freely responded to that grace. As the analogy of Eve/Mary illustrates, Mary’s cooperation was not passive but active. The Dombes Group identified ‘human co-operation’ as an important theological issue. They saw Mary’s cooperation within her relation with the Three Persons of the Trinity: Mary’s ‘cooperation’ is the fruit of an initiative of the Father who looks upon the lowliness of his servant’ (Luke 1:48). It also the fruit of the ‘kenosis’ of the Son who ‘emptied himself†¦and humbled himself’ (Phil 2:7-8). Finally, it is the fruit of the action of the Spirit, who disposes Mary’s heart to be obedient. That is what happened at the moment of her fiat. Mary’s humility is the fruit of the Son’s humility.[18] Intercession: Luther recognizes intercession made to Mary: We ought to call upon her, that for her sake God may grant and do what we request. Thus also all other saints are to be invoked, so that the work may be every way Gods alone.[19] In fact, Luther begins the same homily, asking God to grant him a right understanding: â€Å"†¦through the intercession and for the sake of His dear Mother Mary!†[20] Nevertheless, Luther asserts that we cannot rely on the intercession of another person, â€Å"base your salvation on no other works than those God works in you alone, as you see the Virgin Mary do here. To let the intercessions of others assist you in this is right and proper; we ought all to pray and work for one another. But no one should depend on the works of others, without the works of God in himself.†[21] The Lutheran theologians who took part in the Lutheran-Catholic Dialogue expressed their concern regarding the invocations of the saints and of Mary, which they see as a challenge to the sole mediatorship of Christ, through whom God pours out grace in the Holy Spirit and the â€Å"justifying faith† of the believer.[22] The Lutheran members could accept the saints as examples of Christian life and faith. The Lutherans believe that angels and saints pray for us within the context of Jesus as the one mediator. [23] The Catholic participants in the Lutheran-Catholic Dialogue asserted that the mediation of Mary does not mean that Mary is a source of grace in herself but rather her merciful love is an â€Å"expression and reflection of the mercy of Christ himself.† [24] The Catholic members addressed the question of intercession by saying that Jesus â€Å"is never alone† but is always in the company of His friends, living and dead. Saints illustrate how God’s grace can work in us, they are patterns of holiness and they pray for us. In the Catholic view, we are bonded with millions of other believers throughout the world and throughout time. Those who have preceded us in faith are still connected with us.[25] Catholics see the practice of invoking the saints as an extension of the New Testament practice of intercession (Rom 15:30-32; 2 Cor 1:11; Eph 4:19; Col 4:3) and of the prayer of the righteous (Jas 5:16). Those in heaven have a heightened charity towards those on earth. Marys intercession has exception power because of her divine motherhood. It was recognized that â€Å"prayer† was being used in a broad sense when  directed to Mary and the saints. Protestants had no difficulty with â€Å"praise’ directed to God for the works God has done in Mary. This could even be seen as being done with Mary. For Catholics, intercession was seen as a form of communion. Catholics recognized there have been excesses in Marian piety, which have not been curbed by the Church’s leaders. Nevertheless, the most frequent invocation is to ask Mary to â€Å"pray for us, † in a similar way as the saints are asked to pray for us.[26] Catholics and Protestants agreed that Mary should be honored and God should be praised for the graces given to her. She should be imitated and we should unite ourselves in praising the Father through her. The Protestants were reluctant to invoke her whereas Catholics entrust themselves to her prayers.[27] The Anglican-Catholic Dialogue acknowledged that the English Reformers rejected the notion of the invocation of saints yet the Council of Trent reaffirmed it, emphasizing as it did so that such requests were made to God, â€Å"through his Son our Lord Jesus Christ, who is our sole redeemer and savior† (DS 1821).[28] The Anglican-Catholic document recognized that all ministries in the church, especially those of word and sacrament, mediate the grace of God through human beings. These ministries serve the mediation of Christ and have their power in it. Asking prayers of our brothers and sisters does not diminish the mediatorship of Christ but shows its power through the Spirit.[29] In the experience of communion of prayer, we are aware of the support of those living and dead. With this understanding, it seems that asking saints for prayers is not to be seen as â€Å"unscriptural,† although not directly taught by the scriptures as a required element. Our prayers are not addressed to the saints, but they are asked to pray for us, though this should not be done in a manner that blurs the Trinitarian economy of grace.[30] The authors of the Anglican-Catholic document state: â€Å"Affirming  together unambiguously Christ’s unique mediation, which bears fruit in the life of the Church, we do not consider the practice of asking Mary and the saints to pray for us as communion dividing.†[31]

Loss of Innocence :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Innocence is usually associated with youth and ignorance. The loss of one’s innocence is associated with the evils of the world. However, the term â€Å"innocence† can be interpreted in a variety of ways. Similarly, the loss of one’s innocence can be interpreted in more than one way, and, depending on the interpretation, it may happen numerous times. The loss of innocence is culture specific and involves something that society holds sacrosanct. It is also bounded by different religious beliefs. Still, no matter which culture or religion is at hand, there is always more than one way to lose one’s innocence, and every member of that particular culture or religion experiences a loss of innocence at least once in their lives. In addition, the individual’s loss of innocence will impair him or her emotionally and/or physically.   Ã‚  Ã‚  Ã‚  Ã‚  Committing a crime of some sort will certainly cause an individual to lose his or her innocence with emotional scars and perhaps with physical scars. In Native Son, by Richard Wright, Bigger Thomas accidentally suffocates his boss’ daughter to death. Suddenly, Bigger feels a strength that had been dormant in him, a sense of control and power over another person. Although the murder is accidental, Bigger Thomas experiences a loss of innocence that enables him to kill others also, including his own girlfriend. Yet, with the power he believes he had acquired from his loss of innocence, he also obtains an abundance of guilt and fear. Bigger knows that he had performed a terrible act, and because of this he feels guilty. Also, he begins to fear that he would be caught. Bigger becomes very paranoid after the murder and ultimately is caught and executed anyway. The case of Bigger Thomas is almost tragic. His loss of innocence, an accident, causes him to become a d ishonest and dishonorable person. He is unable to forget the event and bears guilt and fear until he is executed.   Ã‚  Ã‚  Ã‚  Ã‚  Knowing a victim of an unforgettable and unforgivable crime will cause a person to lose a type on innocence. However, witnessing the heinous violation of the victim is much stronger. After the witness sees and hears the exact event, it is nearly impossible to disregard his or her memory. This is true in the short story â€Å"In the Shadow of War.† The protagonist of the literary work, a young boy named Omovo, witnesses the killing of a woman.

Seatbelts :: essays research papers

When travelling at slow speeds in your car the wearing of a seatbelt has little effect of your body when you brake. So why is it important to wear your seat belt? A driver or passenger travelling in a car is moving at the same speed as the car. If the car suddenly stops, the body of the rider inside will keep moving forward at the same speed. This demonstrates inertia. The tendency of a moving object to keep moving, or of a stationary object to remain at rest. Basically Newtons first law; that a body stationary or moving with constant velocity will want to continue to do so, unless acted on by a force. Lets understand what is happening here. First drive along in your car at 60 km/h on a backstreet with no traffic, then brake gently and slowly. You will notice that the seat belt doesn’t really do much to hold your body. Now do the same again but this time break as quickly and sharply as you can. Your body will be thrown forwards with great force, and your seatbelt will be literally holding you in place. Now your body was what is commonly referred to as being "thrown forwards", however this is not the case. Your body was actually not slowing down much at all and your velocity relative to the car initially was much greater. The car began to slow down due to breaking and your body in accordance with Newtons First law wanted to continue to move at the original constant velocity. Now if your seat belt was not there to provide an opposing force, to your momentum and inertia, by holding you from going forwards, you very likely would have been thrown into the dash or steering wheel. Lets look at this mathematically. m= your mass in kilograms for this purposes 70kg V= final velocity 0 m/s U= initial velocity 60 km/h or 16.6 m/s straight line S= distance taken to stop 42 m t= 3.8 a= -4.368 m/s/s Now your momentum at 60km/h is P=MU So P= 70kg*16.6m/s P=1162 Kg m/s Impulse I=MU/t I=70*16.6/3.8 I=305N So your body will weigh about 610kg when you are breaking hard, a force it is difficult for any person to withstand. Now in the context of a head on accident at around 60km/hr the force exerted on your body is greatly increased. In the event of such an accident it will take the car approximately 0.4 seconds to stop.

Shawshank deconstruction for brooks parole sequence

Brooks parole sequence is particularly evocative and compelling. A variety of techniques is used to shape this particularly emotive and tragic scene. These techniques include the use of camera shots, background music, voice over, lighting and dialogue. Our first impression of â€Å"Brooks parole† sequence is shaped through the use of variety of camera shots. The use of long panning camera shots of Brooks standing still, alone outside Shawshank's gates highlights how frail, small and insignificant he is in the outside world. These camera shots emphasise and gives us the sense of Brooks loss, being alone frightened, scared and anxious. This is further highlighted by the close up camera shots of Brooks in the bus after being released, gripping onto the handle rails. In this camera shot the other passengers on the bus are blurred putting our focus and attention on Brooks, leaving the audience with a great sense of absolute despair, anxiety and loss. The use of this camera technique gives us our last impression of the broken man Brooks had become after leaving Shawshank. The use of these powerful camera techniques used by the director emphasises Brooks feeling of being alone, frightened and anxious. Highlighting further, the impa ct Shawshank has on the individual. The use of background music highlights further Brooks loneliness and despair. The background music is sad, somber and builds in intensity throughout this sequence. The music creates a mood, an atmosphere of loss, shock as we sense Brooks defeat and horror. There is an irony in the fact that Brooks is physically free but emotionally trapped and imprisoned by his sense of solitude and isolation in the outside world, where he should be feeling free. The use of background music leaves us with a strong impression that Brooks freedom will have a tragic end due to him being in a state of despair. In this emotion charged sequence, it is Brooks voice that we hear speaking directly to us, about his thoughts and feelings about his ‘release' from Shawshank. This voice over technique emphasizes Brooks strong sense of not belonging on the outside world. The language used in this voice over is very moving as we feel Brooks pain and desperation to be back in Shawshank. † Send me home, I'm tired of being afraid all the time.† The use of voice over tragically emphasizes just how much Shawshank can take from an individual. Inside Shawshank Brooks had, ‘friends,' ‘family' and ‘position' which made him feel important. This powerful technique highlights that, Shawshank can tragically strip away a man's sense of self. A man becomes dependent on the walls of the institution. â€Å"First you hate them, then you start to get used to them and pretty soon you start depending on them.† Brooks believed that outside of Shawshank he was nothing. This sequence is also shaped through the use of a variety of lighting, which emphasises Brooks feelings of depression and worthlessness and that he can't see himself escaping this dark, unforgiving place. These characteristics are portrayed through the use of dull, dim, dark and shadowy lighting. Ironically, the confinement of Shawshank offered Brooks a security that being on the ‘outside' could not, leaving us to believe that Brooks had become institutionalised. Dialogue is another strong technique used by the director to show a startling contrast in the language used by the guards who farewell Brooks. They shake his hand and wish him ‘good luck'. Their language and their treatment of Brooks contrasts markedly to what we have seen and heard within Shawshank. The cruelty, brutality and taunting are gone. The words and gestures used by the guards highlights the respect they have for Brooks and for us makes his leaving a lot more touching. This evocative and compelling parole sequence is shaped through the use of many techniques, which leads us towards the tragic ending of Brooks at the end of this sequence.

The Thread of History

The Thread of History Any society can be compared to a living organism that gets born, grows and changes according to the time, environment and processes that go on internally. Any group of people has their own beliefs and regulations which are backed up by history, traditions and culture.Advertising We will write a custom research paper sample on The Thread of History specifically for you for only $16.05 $11/page Learn More In any society there are people who get their opinion widely known and they are sometimes called visionaries. For the past twenty years, society has experienced many rapid changes, and thinkers and writers often offered their opinions, as to what is going on under the surface and where the present world is going to be in the future. All societies have intricate traditions and structures with work and leisure time. One of the oldest activities that people are engaged in is sports or any kind of physical games. Steve Craig, in his book titled â€Å"Sports and Games of the Ancients† looks at how societies view games and how they are comprehended personally and socially. One of the important points is that each society has a form of games that are played publicly, for people’s entertainment. Socially, it says several things, as the population is very multifaceted. Primarily, it is that people need a form of entertainment that can be watched live. People are interested in seeing other fellow human beings in action and the key feature of the sport which is its unpredictability makes the viewing even more exciting and desired. The unique nature of games is very original because it cannot be fully predicted and people are drawn to that (Craig 1). Comparing to the television, where people are playing out formed scripts, games are much different. Even though previously, in the early days, there were games and the need for them, people’s interest and commercialization have grown immensely at the onset of television and other m ass media. This led to people wanting more and expecting sights that were non-existent before. It begs a question of why do people really need entertainment and what would happen without it. It is a part of human soul and emotional existence, as without it, people would have work and duties that are a part of the routine and not feelings. A close connection to the pleasures of life is explored by Deborah Blum in her book â€Å"Love at Goon Park: Harry Harlow and the Science of Affection†. Just as people need mass and public entertainment, they need affection and love. This is one of the starting points in life and it very much sets up the rest of a person’s development. It is interesting that the way a person will feel about themselves, others, their ability to be in public places, feel confidence and connection to people; all these things get influenced by how the infant and child are treated.Advertising Looking for research paper on social sciences?

The experiments proved that baby monkey sometimes needed affection and â€Å"warmth† of their mother more than food. This and other experiments, as well as the views of Deborah Blum reiterate the fact that people need love and any society must have healthy and loving individuals for the whole nation or country to prosper (Blum 15). In a work titled â€Å"The Pyrotechnic Insanitarium: American Culture on the Brink†, Mark Dery describes a new age of life and society. The twenty first century has brought many changes and the focus can be seen on the rapid development of entertainment but also, on the negatives and short backs of society. The conspiracy theory is mentioned, and people start to realize that in the fast moving world there are things that could be unseen and under the surface. It is somewhat re bated by saying that in reality, there are no conspiracies and the politics are very much openly viewed but it does not seem convincing. The entertainment and pleasures of people are going hand in hand with the horrors that human mind offers. With the increasing crime rates and technological advancement, people are receiving more information and problems to deal with. The heights of human brain power are allowing predicting that the future will bring even more challenges and people will face something that has never been seen before (Dery 30). It is very true that human mind is still a mystery and it is quite difficult to see what people are capable of. Alfred Lubrano discuses another part of the changing world in a book titled â€Å"Limbo: Blue-Collar Roots, White-Collar Dreams†. He especially points to the division between people socially and personally. For as long as there has been humanity, people have had different duties according to own views but also to the world aro und them. The division between the working and the middle class is what Alfred Lubrano talks about. He describes the qualities of people who are born to be a part of the middle class and that there is no way of becoming anything else. It touches upon the moral issue of a person desiring what they want to do in their life but at the same time, creating opportunities to achieve whatever it is they strive to reach. Education is mentioned as an important part of the process in becoming successful and this reflects in the scope of bigger things in society. This is becoming very true in any part of the world, as the evolution of technologies and workforce is delving into a different sphere, uncommon to the previous century. The world is becoming business oriented and there are many individuals who consider it their life’s calling to become a part of it (Lubrano 10).Advertising We will write a custom research paper sample on The Thread of History specifically for you for o nly $16.05 $11/page Learn More Vivian Sobchack takes a look at the modern society and examines the future in the work titled â€Å"Carnal Thoughts: Embodiment and Moving Image Culture†.

She refers to â€Å"Hansel and Gretel† in relation to the fact that without the â€Å"breadcrumbs† people might become lost (Sobchack 13). This representation is meant to show that people need guidance. The future world has many mysteries and people need organization and each other’s help to find the way. The world is becoming divided into spaces that are foreign and sometimes, unequal. Even though this is an age of knowledge and people’s rights, there is still much to learn, especially in the relationship between people and different groups. Vivian Sobchack qualifies people as being lost in the world, not knowing what to do and how to adjust to the fa st moving pace. There starts to evolve a sort of separation between the world and the masses, and an individual is not aware of what is expected of them regarding themselves and society. People start to create false realities and whatever they think is right, eventually becomes empty space and people are forced to re-think their goals and dreams. Another look at the modern world and the way it is being run is taken by Linda Seger in a book â€Å"Jesus Rode a Donkey: Why Republicans Dont Have the Corner on Christ†. The author compares people’s religious beliefs to the political system and what is expects and required of people (Seger 7). Many are faced with sacrifices that have to be made for the system to prosper. But there is also a different side of the coin, where others get rich at the expense of people who are fulfilling their duty to be a good citizen. Linda Seger reinforces that in order for people to go into the future, they must be understanding and kind to ea ch other. The simplicity of their actions and straightforward manner will create best conditions of life for all human beings. The new age has given people power to vote for their leaders and enjoy the rights and freedoms that are naturally given but is unclear what these freedoms can sometimes bring. All the writers and thinkers have a very common theme that centers on people which is their needs and the evolving society. People want to be happy and keep finding ways of how to enjoy the life. Even though the majority bases their existence on goodness, there are those who want to use the population and gain more than is needed. This leads to an important question of the changing world and the expectancies that people have towards it. It must be just and equal to all and this should be the motto of the future. Blum, Deborah.

Accounting Essay Example

Accounting Essay Example Accounting Essay – Coursework Example Topic:Â   Accounting Essay The rules of debit and credit as applied to various accounts in financial accounting are specific. Each transaction in a particular account is recorded twice according to financial accounting rules. The different accounts in financial accounting are assets account, liabilities accounts, owner’s equity account, revenues account and expense account. In financial accounting, the debit and credit are positioned on the left and ride side of the financial statement. In case of assets accounts an increase in asset is recorded on the left hand side whereas the decrease in asset comes on right side. For example a purchase of machinery is recorded on left and sale of machinery is shown on rights hand side of financial statement. In the case of liabilities accounts an increase in liability will be posted on credit side and decrease is recorded on debit side. if an organization has accounts payable then it will be recorded on the credit side while accounts rece ivables recorded on the debit side .Owner’s equity account is a owner’s capital account where the increase and decrease in the owner’s profitability is projected. Here a purchase of asset will be posted on debit side whereas sale of asset comes on credit side. In case of revenue account an increase in asset is debited while decrease in asset is credited. In expense account the salary paid to employees will be credited and interest received will be debited. So every transaction is balanced out by recording them on the debit and credit side of an account.

Free Essays on Anna Kingsly

In the early years of the nineteenth century, the population of Spanish Florida was small but diverse. Americans and Europeans came seeking wealth by obtaining land and establishing plantations; furthermore, the forced labor of enslaved Africans secured that wealth. Those Africans who were freed by their owners or who purchased their own freedom became farmers, tradesmen, or black militiamen who helped protect the colony. On the frontier, away from the settlements and plantations, the Seminole Indians and the Black Seminoles kept an uneasy vigil on the encroaching development of Florida. Among those striving for freedom and security in Spanish Florida was Anna Kingsley. Anna was the African wife of plantation owner Zephaniah Kingsley. At an early age, she survived the Middle Passage and dehumanizing slave markets to become the property of Kingsley. After manumission by her husband, Anna became a landowner and slaveholder. She raised her four children while managing a plantation that utilized African slave labor. She survived brutal changes in race policies and social attitudes brought by successive governments in Florida, but survival demanded difficult, often dangerous, choices. Anna Kingsley was a woman of courage and determination. She is an example of the active role that people of color played in shaping their own destinies and our country’s history in an era of slavery, oppression, and prejudice. She left, however, no personal descriptions of her life. She was not a famous or powerful person who figured prominently in accounts of that era. Today we must find Anna in the official documents of her time and in the historic structures that she inhabited. There her story may be discovered. On the first day of March 1811, in the Spanish province of East Florida, white plantation owner Zephaniah Kingsley put his signature on a document that forever changed the life of a young African woman.

French Politics and Institutions Essay Example | Topics and Well Written Essays - 1250 words

French Politics and Institutions - Essay Example In the Toulouse shooting there were four Jews killed outside of a Jewish school, three of those dead being children. Just like in the past incident, the Toulouse shooting sparked riots in France with the society divided between those who supported Bayne and those who condemn him. Therefore, other separate incidents similar to the recent shooting should work as a highlight and a warning sign rather than being treated as a lone incident. Unlike in North America where issues affecting the Jewish community there are low birth rates, intermarriages and assimilation, in French Europe, anti-Semitism is a social phenomenon rather than just a lone incident1. The strong outspoken French public take on the two incidents has worked in highlighting the similarity between both incidents. The society seems, just like in the first incident, to be very active in taking sides - either on the side of the victims or on the side of the perpetrators. The underlying crimes are based on hate. However, there have been recent twists to this anti-Semitism in that political and economic spheres have been introduced into the debate but the fact remains that anti-Semitism just like in those periods of 1890s still is strong if not getting even stronger in France. Even scholars have been thrown into different conclusions about the recent incident in line with the Dreyfus Affair in that some like Neocon John Podhoretz are declaring an alert that â€Å"Jews are being hunted.† Though an overtone, it seeks to highlight that the recent event cannot be looked at in isolation to the 1894 anti-Semitic affair because of the similarity between them. On the contrary Leon Weiseltier termed his article â€Å"Hitler is dead.† In essence, the writer is telling the Jews in the Diaspora that they should not panic. These two authors could be taken to be social representatives in the voicing of how society in France takes up positions when these issues are brought to light in the French public dom ain2. The fact that even those denying the latest shooting incident are referring to the contrast between the two incidents only raises concerns about the similarities between the incidents which are more than 100 years apart. It is therefore not uncommon to find political leaders in search of public support or mere social debate in quest to remain relevant talking about the two events and dragging anti-Semitism into the contemporary political and economic circles. Despite the country’s enormous steps in technology, economy and political spheres, the culture of anti-Semitism has remained deeply enshrined among some parts of the society. The recent shooting does not therefore represent a separate aspect of the French population but a rather serious social phenomenon. It can also be seen as a serious social evil because the shooter in the recent Toulouse shooting definitely was not even born when the Dreyfus affair was happening. Examination of the Ability of France to Divide O ver Issues The study has already established that one similarity between the Dreyfus Affair and the recent Toulouse shooting has been the characterization of the French public to divide into two different camps when social phenomena take place. Hence, while others openly support the individuals who perform the anti-Semitic activities such as the ones noted above, others strongly condemn them in equal matters. This has historically been the French scenario. Taking the scene in

Putting telescopes in space have the following advantages compared with the use of ground-based telescopes: (1) the lack of atmosphere, which makes it possible to see things in space that are otherwise blocked at certain wavelengths when trying to view them from the ground; (2) going out into space reduces the temperature at which the telescope operates, further improving image resolution and the performance of the detector arrays and other optoelectronic devices on board; and (3) it is much darker in space than it is on the ground, which makes it easier to see objects that are far away (PennWell Corporation, 2004, pars. 3 & 4). gone before. Retrieved 19 August 2010. The NASA define a dwarf planet as â€Å"a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite† (NASA, 2010, par. 3). Pluto was reclassified by the IAU as a dwarf planet because of the provision: it has not â€Å"cleared the neighborhood† around its orbit; meaning â€Å"as planets form, they become the dominant gravitational body in their orbit in the Solar System. As they interact with other, smaller objects, they either consume them, or sling them away with their gravity.

Making Connection between Black and White, Changing America and Civil Essay

Making Connection between Black and White, Changing America and Civil Disobidience - Essay Example These authors commonly discuss the problems of American society such as racial divide, immigrant problems, and assimilation of the people of other races into the mainstream white society. Though Goodale’s and Swerdlow’s approach to the problems of American society are more descriptive than prescriptive, Thoreau’s approach is quite prescriptive. He suggests that people of American society seem to be affected with a racial, cultural, political and religious identity confusion. Yet an American’s national identity is composed of a diverse but uniquely uniformed nationality including all of the contradictions. While the uniformity of the American nationality is ensured by a geographical unity, America is a heterogeneous society that contains diverse races, cultures, nationalities, religions, etc. Still American heterogeneous nationality is affected with a number of complexities. In her article, â€Å"Black and White†, Gloria Goodale addresses this racial divide within the heart of American society, whereas Joel Swerdlow, the author of â€Å"Changing America† depicts the changes that America’s racial identity has undergone and still is undergoing. On the other hand, though Henry David Thoreau’s â€Å"Civil Disobedience† deals with the sort of political protest an American should adopt in order to dissent what he or she does not support or think right. Though apparently Thoreau’s proposition â€Å"to withdraw from an evil† relates much to a man’s, especially an American’s, political life, such stance can help dispensing the racial divide in the American society.

Discuss the character of Achilles in Homers Hiad Essay

Discuss the character of Achilles in Homers Hiad - Essay Example Thus, Achilles can be seen as suffering an existential crisis in which he has to fight for glory, which his ultimate pursuit in life, and he knows his quest will cost him his life. A born soldier adept in the art of killing, Achilles also wants to pursue glory, like many other Greek heroes. This perception of the virtue of life takes him to Troy, to fight one of the most significant wars in human history. It becomes relevant here that before coming to Troy his mother, the sea-nymph goddess Thetis has warned him that he will die in the war. An ordinary human may have been intimidated by this situation, but Achilles decides to continue the pursuit of glory rather than avoid his death. The basic problem of his existential crisis stem from this decision and defiant nature that does not want to cringe at the dictates of the gods or the designs of fate. Thus, as befitting a hero of immaculate courage, Achilles leads his men to the battle and fights it with valor, driven by his quest for glory. The usual heroes one encounters in epical stories are God-fearing men, who acquiesce to the dictates of fate and the gods. However, Achilles seems to a person who rather will pursue the glory that belongs to heroes, who do what they must do to attain it, irrespective of what the gods have decided as his fate. Similarly, he does not acquiesce blindly to his leader but revolts when Agamemnon bruises his honor by taking his prize, Briseis. This makes him a character that has both positive and negative traits that mark the nature of normal humans as opposed to legendary heroes. Similarly, he defiles the dead body of Hector as an act of vengeance for killing his most beloved person, Patroclus. Usual heroes, considered as kind and forgiving, do not display such traits and, thereby, Iliad portrays Achilles as the first true individual who has both problematic characteristics. On the other hand,

Gregor and Meursault are certainly problematic characters. What is the Essay - 1

Gregor and Meursault are certainly problematic characters. What is the main problem both confront - Essay Example Therefore Gregor’s alienation is less deliberate than Meursault’s alienation, as Rossignol says, â€Å"GREGOR’S alienation is slightly less deliberate. Used as a tool for money and for control by his family, yet has been indoctrinated in only seeing their good side (if it exists). This however also stems from self-denial and self-alienation.† (56) Apparently Gregor seems to be the poor victim of the society, in which he lives, that cruelly has robbed him of all of the opportunities to survive decently on his own worth, gradually restricting him within the periphery of a room. Ironically the way how Gregor views others in his family and orientates himself in the society essentially shows that Gregor’s psychological inertia has reached the height that prevents him from looking into his discomfiture and from identifying the causes. He cannot -more appropriately, does not want to- search for the underlying reasons of the discomfiture. Gregor simply take s the discomfiture as it is. Such non-resistive acceptance of the situation as well as the humiliation inflicted by his family members is reminiscent of Meursault’s disinterest in the ‘well and woe’ of life and other social affairs. Whereas Gregor’s self-alienation is illusive and evading, Meursault’s self alienation is more obvious. Indeed the psychological inertia of Kafka’s protagonist is camouflaged in his apparently innocent stance that invokes the readers’ sympathy towards him against the hostility of the family members. The root of Meursault’s alienation lies in his disinterest in social affairs. Again his disinterestedness evolves from the meaninglessness or the absurdity of life. Both Meursault and Gregor deceive themselves and subsequently their deceptions result their isolation from their societies. In this regard, Rossignol says, â€Å"In L’Étranger (Camus) and The Metamorphosis

Causes of Cardiovascular Disease | Literature Review

Causes of Cardiovascular Disease | Literature Review 2 Abstract 3 Introduction 3.1 Cardiovascular Disease Cardiovascular disease (CVD) is the broad class of diseases that involves the heart or/and blood vessels. CVD includes atherosclerosis, heart valve disease, arrhythmia, heart failure, hypertension, endocarditis, diseases of the aorta, disorders of the peripheral vascular system, and congenital heart disease [1]. However, atherosclerosis accounts for the major part of CVD (up to xx%), and sometimes CVD is misleading used as a synonym for atherosclerosis [REF]. Because atherosclerosis is the underlying disease of several CVD, part of patients, where one diagnosis of CVD became manifest, may present with further co-morbidities, especially other diagnosis of CVD are common. However, the portion of patients with co-morbidities is depending on the baseline disease [2-4]. For example 40-60% of patients with Peripheral Arterial Disease (PAD) also have coronary artery disease (CAD) and cerebral artery disease, but only 10-30% of patients with CAD have also PAD (Figure 1) [2, 4]. Further, the severity of cardiovascular co-morbidities correlates well with each other[5-7]. CVD is today responsible for ca. 30% of all deaths worldwide [8], while heart disease and stroke are the leading causes of mortality and disability in developed countries [9]. Although the mortality rates of CVD has a considerable variation across countries (xx% in xx to xx% in xx) [10], a common trend of increasing rates has been observed worldwide. Before 1900, infectious diseases and malnutrition were the most common causes of death throughout the world, and CVD was responsible for The economic burden and the public health costs are mainly driven by CVD. In terms of combined morbidity and mortality, 148 million Disability-Adjusted Life-Years (DALYs) were lost worldwide (2002), which represents about 10% of all lost DALYs [REF]. In 2008, CVD costs about 192 billion Euros a year alone in the European Union, which results in a per capita cost of 391 Euros [13]. 3.1.1 Atherosclerosis Atherosclerosis is the most frequent and important pattern of Arteriosclerosis, other forms of Arteriosclerosis are Mà ¶nckeberg medial calcific sclerosis and Arteriolosclerosis, which vary in pathophysiological and clinical presentation [14]. As described above (3.1), atherosclerosis is the leading cause of death (up to 30%) in developed countries and represents the major portion of CVD. Atherosclerosis (literal origin from Greek: athero = â€Å"gruel or paste†; sclerosis = â€Å"hardness†) is defined as â€Å"thickening and loss of elasticity of arterial walls† and describes a process, where fatty substances, cholesterol, cellular waste products, calcium and fibrin building up in the inner lining of arteries [14]. These intimal lesions are called â€Å"atheromas†, â€Å"atheromatous† or â€Å"fibrofatty plaques†, which lead into an obstruction of vascular lumens and weakness the underlying media. Even within a given arterial bed, lesions or stenoses due to atherosclerosis tend to occur focally, typically in certain predisposed regions. 3.1.1.1 Pathogenesis of Atherosclerosis Due to overwhelming importance of atherosclerosis, enormous efforts have been spent to discover its cause over the last few decades. Today, the currently accepted concept, so called â€Å"the response to injury hypothesis†, considers atherosclerosis to be a chronic inflammatory response of the arterial wall initiated by injury to the endothelium [15]. Furthermore, lesion initiation and progression are sustained by interaction between lipoproteins, macrophages, T-lymphocytes, and the normal cellular constituents of the arterial wall. This process of developing atherosclerosis, which typically lasts over a period of many years usually many decades, can be divided into several consecutive steps, as illustrated in Figure 2 [REF]. Parallel, a morphological change is observed within the artery wall, where fatty streak represents the initial morphological lesion, even so the pathogenesis has started quite earlier with a chronic endothelial injury [REF]. Figure 2: Illustration of the Pathogenesis and Morphological Development of Atherosclerosis. SMC: Smooth muscle Cell; 6 ÃŽ ¼m thick histology slices of coronary arteries stained with Movats pentachrome. A: pathological intimal thickening with a â€Å"fatty streak†; B: pathological intimal thickening with a macrophage infiltration; C: early fibroatheroma with neoangiogenesis; D: fibroatheroma with thin fibrous cap and a healed rupture; E; late fibroatheroma with a sheet calcification. * demarks necrotic scores. Histology performed by CVPath Laboratory, Maryland, MD. The below described steps of the pathogenesis of atherosclerosis shouldnt been seen as a separated processes. They are interconnected and occur parallel. Further, several mechanism of vicious circles are described [REF]. However, the stratification into the flowing six steps helps to understand the complex pathogenesis and represents the current understanding: (1) Chronic Endothelia Injury As the earliest step in the pathogenesis of atherosclerosis, endothelial activation and chronic injury, also known as endothelial dysfunction, have been described [16]. The following factors contributed in different extent to endothelial dysfunction and are partly known as traditional risk factors for atherosclerosis [17]: advancing age, dyslipidemia, hypertension, increased levels angiotensin, insulin resistance and diabetes, smoking, estrogen deficiency. Several biochemical pathways have been described for those factors increasing the endothelial dysfunction. Other factors like hyperhomocysteinemia, possible infection and especially low or oscillatory shear stress are still discussed whether they significantly contribute to endothelial dysfunction [18-22]. The phenotypic features of endothelial dysfunction are described as the reduced vasodilator and increased vasoconstrictor capacity, an enhanced leukocyte adhesion, an increase of pro-thrombotic and decrease of fibrinolytic activi ty, and an increase in growth-promoting. (2) Accommodation and Oxidation of Lipoproteins In addition and due the endothelial dysfunction lipoproteins, especially low density lipoprotein (LDL), sequestered from plasma in the extracellular space of the arterial intima. Beside the extent of endothelial dysfunction, this process is depending on the concentration of LDL in the blood circulation [23]. Even so several mechanisms have been proposed for transport of LDL into the arterial intima including vesicular ferrying through endothelial cells, passive sieving through endothelial-cell pores, passage between cells, its not finally understand. However, strong evidence exist, that the accommodation of LDL in the arterial intima is not only a passive effect by a â€Å"leaking† vascular endothelium [REF]. Part of the lipoproteins that have entered the arterial wall stay there and are modified subsequently. Especially the modification of the lipoproteins has a trapping function for die selbigen [24]. The most common modification is the oxidation of lipoproteins, giving rise to hydroperoxides, lysophospholipids, oxysterols, and aldehydic breakdown products of fatty acids and phospholipids. But further modification like fusion of lipoproteins, proteolysis, lipolytic degradation and glycation are well known [25]. Such modified lipoproteins or particles of the modification process have inflammatory potential and trigger a local inflammatory response responsible for signaling subsequent steps in the atherogenesis. It includes a further increased endothelial dysfunction, which may cause a vicious circle of LDL accumulation, and activation of various cell types [24, 26, 27]. (3) Migration of Monocytes and Transformation into Macrophages/Foam Cells More important, the inflammatory response induces migration of leukocytes such as monocytes or lymphocytes into the lesion. Leukocytes are attracted by chemoattractant factors including modified lipoprotein particles themselves and chemoattractant cytokines depicted by the smaller spheres, such as the chemokine monocyte chemoattractant protein-1, interleukin 1 (IL-1) or tumor necrosis factor alpha (TNF-ÃŽ ±) produced by vascular wall cells in response to the inflammatory process [REF]. The activated arterial endothelial cells express a number of adhesion molecules and receptors on their surface, which participate in the recruitment of leukocytes from the blood to the nascent lesion [REF]. Macrophages are a key player in atherogenesis [27]. They develop from recruited monocytes, which migrated as described above into the lesion. In the mediator stimulated process of maturation, those macrophages become lipid-laden foam cells by uptake of lipoprotein particles through receptor-mediated endocytosis [REF]. The accumulation of lipid in the macrophages results in the apoptosis and necrosis, which lead first to a boosted expression and secretion of inflammatory cytokines and second to a release of their lipid excess into a necrotic lipid-core [REF]. Macrophages further produce enzymes, such as metalloproteinases, that degrade the extracellular matrix and lead to instability of plaques [REF]. (4) Adhesion of platelets and Release of SMC activating factors The inflammatory process, especially triggered by the necrosis of the foam cells, microscopic breaches in endothelial integrity may occur. Platelets adhere to such sites of limited endothelial denudation owing to exposure of the thrombogenic extracellular matrix of the underlying basement membrane and form microthrombi. Although most of the arterial mural microthrombi resolve without any clinical manifestation, they lead indirectly to lesion progression by pro-fibrotic stimulation [REF]. The platelets, activated by adhesion, release numerous factors that promote a fibrotic response, including platelet-derived growth factor (PDGF), fibroblast growth factor (FGF), insulin-like growth factor 1 (IGF-1), and transforming growth factor alpha (TGF-ÃŽ ±) [28-30]. Thrombin itself generates fibrin that has a pro-fibrotic stimulus [28]. (5) Migration and Proliferation of SMCs The pro-fibrotic response includes first the migration of SMC from the media of the arterial wall, through the internal elastic membrane, and the accumulation within the expanding intima of the arterial wall. Second, stimulate the proliferation of SMC, which is responsible to form the bulk of the advanced lesion. Another part of the advanced lesions is an increased extracellular matrix. TGF-ÃŽ ± and other mediators stimulate the interstitial collagen production by SMC. These mediators may arise not only from neighboring endothelial cells or leukocytes (a paracrine pathway) but also from the same cell that responds to the factor (an autocrine pathway). Together, these alterations in smooth-muscle cells, signaled by these mediators acting at short distances, can accelerate transformation of the early lesion (fatty streak) into a more fibrous SMC and extracellular matrix-rich plaque. (6) Enhanced accumulation of lipids, collagen and proteoglycans The formation of a complex atherosclerotic lesion is characteristic by an extent remodeling process. Further foam cells within the expanding intimal lesion perish, while they phagocytose more and more lipids. The fibrotic cap between the so arisen lipid-rich necrotic core and the vascular lumen may vary in thickness and allows the classification of â€Å"thin cap fibroatheroma†, which correlates with a higher risk for acute luminal thrombosis [REF]. The production of extracellular matrix, as well plaque evolution and complication can be stimulated by diverse growth factors or cytokines like IL-1 or TNF-ÃŽ ±, and can be inhibited by other cytokines (e.g. interferon alpha (IFN-ÃŽ ±)) [REF]. As atherosclerotic plaques advance, they show intimal arterial calcification [REF]. The same proteins, which can be found in bone, are also localize in atherosclerotic lesions, e.g., osteocalcin, osteopontin, and bone morphogenetic proteins [31]. Both, passive and active models are discussed for the development calcification [32]. SMC can, promoted by several cytokines (e.g. transcription core binding factor ÃŽ ±1), acquire osteoblast-like characteristics and secrete bone matrix [33]. These examples illustrate how the pathogenesis of atherosclerosis involves a complex mix of mediators that in the balance determines the characteristics of particular lesions [REF]. 3.1.1.2 The Role of Inflammation The role of inflammation is central, while those inflammatory mechanisms mediate initiation, progression, and the complications of atherosclerotic lesions [26, 34]. Through the inflammatory process, arterial endothelial cells begin to express on their surface selective adhesion molecules that bind various classes of leukocytes, especially monocyte and T lymphocyte which are found in early human and experimental atheroma [REF]. After monocytes adhere to the endothelium, they can first migrate in the intima, largely stimulated by chemokines; and second transform into macrophages and avidly engulf lipoproteins, largely oxidized LDL [REF]. Although the phagocytosis of potentially harmful lipid particles by macrophages and subsequently the transformation into foam cells has an initially protective, this process involves further expression and secretion of inflammatory chemokines like Interleukin (IL)-1, Monocyte Chemotactic Protein (MCP)-1 or Tumor Necrosis Factor (TNF)-ÃŽ ±. Those enhanc e the inflammatory reaction and enable the further migration of leukocytes into the lesion [REF]. Macrophages also produce toxic oxygen species that cause additional oxidation of the LDL in the lesions, and they elaborate growth factors that may contribute to SMC proliferation [REF]. Similary, T lymphocytes (both CD4+ and CD8+) are also recruited to the intima by chemo-attractants. Cross-talk between macrophages and T cells induces a chronic inflammatory state regarding cellular and humoral immune activation characteristics. This state of a chronic inflammation leads also to the next observed steps in the development and progression of atherosclerosis. Thus, it stimulates the migration and proliferation of smooth muscle cells (SMC), as well the proliferation of vascular endothelial cells in the lesion. Through fibrogenic mediators, released from activated leukocytes and intrinsic arterial cells, the replication of SMCs is getting enhanced and contributes to elaboration by these cells of a dense extracellular matrix characteristic of the more advanced atherosclerotic lesion. 3.1.1.3 Vasa Vasorum and Neo-Angiogenesis The vasa vasorum of the aorta is as a plexus in the wall of artery of microvessels, which are functional endarteries [35, 36]. They either originate from major branches, originate from the main lumen of the aorta or drain in concomitant veins [37]. These vessels allow the humoral communication between intravascular lumen, vessel wall and adventitial layer of large arteries including oxygen and nutrients supply [REF]. Several studies demonstrated that hypoxia [38], cytokines (e.g. vascular endothelial growth factor) [39, 40], pro-angiogenic factors (e.g. hypertension or hypercholesterolemia) stimulate the growth of the vasa vasorum [41]. Those increased microvascular network may contribute to inflammation and lesion complications in several ways. First, the vasa vasorum provides an abundant surface area for leukocytes trafficking and may serve as the portal of entry and exit of white blood cells from the established atheroma. Microvessels in the plaques may also furnish foci for intraplaque hemorrhage. Like the neovessels in the diabetic retina, microvessels in the atheroma may be friable and prone to rupture and can produce focal hemorrhage. Such a vascular leak leads to thrombosis in situ and thrombin generation from prothrombin. In addition to its role in blood coagulation, thrombin can modulate many aspects of vascular cell function, as described above. Atherosclerotic plaques often contain fibrin and hemosiderin, an indication that episodes of intraplaque hemorrhage contribute to plaque complications. Multiple and often competing signals regulate these various cellular events. Increasingly, we appreciate links between atherogenic risk factors, inflammation, and the altered behavior of intrinsic vascular wall cells and infiltrating leukocytes that underlie the complex pathogenesis of these lesions. The present data indicate that vasa vasorum neoangiogenesis and atherosclerosis are seemingly inseparably linked, triggered and perpetuated by inflammatory reactions within the vascular wall. 3.1.1.4 Risk Factors for Development of Atherosclerosis Local shear stress In the coronary circulation, for example, the proximal left anterior descending coronary artery exhibits a particular predilection for developing atherosclerotic disease. Likewise, atherosclerosis preferentially affects the proximal portions of the renal arteries and, in the extracranial circulation to the brain, the carotid bifurcation. Indeed, atherosclerotic lesions often form at branching points of arteries, regions of disturbed blood flow. Age, Gender, HTN, HLP, DM, Smoking, Race/Ethnicity, 3.1.1.5 Atherosclerosis of the Aorta In the characteristic distribution of atherosclerotic plaques in humans the abdominal aorta (Fig. 11-8) is usually much more involved than the thoracic aorta, and lesions tend to be much more prominent around the origins (ostia) of major branches. In descending order (after the lower abdominal aorta), the most heavily involved vessels are the coronary arteries, the popliteal arteries, the internal carotid arteries, and the vessels of the circle of Willis. Vessels of the upper extremities are usually spared, as are the mesenteric and renal arteries, except at their ostia. Nevertheless, in an individual case, the severity of atherosclerosis in one artery does not predict the severity in another. In an individual, and indeed within a particular artery, lesions at various stages often coexist. 2009_Dijk_The natural history of aortic atherosclerosis_A systematic histopathological evaluation of the peri-renal region.pdf 3.1.2 Peripheral Arterial Disease Peripheral Arterial Disease (PAD) is caused by atherosclerosis and represents the most common cause of lower extremity ischemic syndromes in developed countries [42]. Symptoms of PAD are variable including pain, ache, hair loss, thickened nails, smooth and shiny skin, reduced skin temperature, cramp, muscle atrophy, or a sense of fatigue in the muscles. Because of the variability of symptoms, the diagnosis of PDA is frequently missed [43]. In addition, the major part of patients with PAD is asymptomatic [REF]. Beside these diagnostic challenges, PAD affects a large and increasing numbers of patients worldwide. Round 30 million people are diseased in worldwide, but of those only 10 million patients are presenting with symptoms [44]. Further, the prevalence is increasing with age [6, 45], while the prevalence is 10% at the age of 60 years [46]. Association to mortality!!! 3.1.2.1 Pathogenesis of Peripheral Artery Disease The leading cause of PAD is atherosclerosis, especially in older patients (>40 years) and at the lower extremities [42]. Other, but rare causes of PAD include embolism, vasculitis, fibromuscular dysplasia, entrapment, and trauma. Atherosclerotic lesions, which are segmental and cause stenosis, are usually localized to large and medium-sized vessels. The pathology of these lesions is based on atherosclerotic plaques development, as described above (xxx). The primary sites of involvement are the abdominal aorta and iliac arteries (30% of symptomatic patients), the femoral and popliteal arteries (80-90%), and the more distal arteries (40-50%) [REF]. Atherosclerotic lesions have been predominantly observed at arterial branch points. These may be explained by altered shear stress [REF]. However, the involvement of the distal and smaller arteries is more common in elderly individuals and patients with diabetes mellitus [REF]. 3.1.2.2 Risk Factors for Peripheral Arterial Disease While atherosclerosis is the major underlying condition of PAD, the risk factors for PAD are essentially the same as those for other form of atherosclerosis (like e.g. CAD), see Table 1 [47-50]. However, the risk factors smoking and diabetes may have even greater effect for PAD as compared for CAD [51]. Risk Factors Increased risk for PAD Hypercholesterolemia 1- to 2-fold (low) Homocysteinemia 1- to 3-fold (moderate) Hypertension 1- to 3-fold (moderate) Smoking (current and past) 2- to 4-fold (high) Diabetes mellitus 2- to 4-fold (high) Table 1: Risk Factors for Peripheral Arterial Disease 3.1.2.3 Clinical Presentation of Peripheral Artery Disease PAD affects more often the lower extremities (xx times more often than upper extremities) [REF]. The most common symptom of PAD is intermittent claudication, which is defined as presence of pain, ache, cramp, numbness, or a sense of fatigue in the muscles. Those symptoms occur during exercise and are relieved by rest, as result of the increased muscle ischemia during exercise caused by obstruction to arterial flow. Patients with PAD in the lower extremities resulting in ischemia may range in presentation from no symptoms to limb-threatening gangrene. Two major classifications based on the clinical presentations are established, the Fontaine and the Rutherford classification. While the more simple Fontaine classification consists of four stages (Table 2) [52], the Rutherford classification has four grades (0-III) and seven categories (0-6). Asymptomatic patients are classified into Rutherford category 0. Any patient with claudicants are stratified into Rutherford grade I and divided into three categories based on the severity of the symptoms. If patients have pain at rest, they belong to Rutherford grade II and category 4. Any patient with tissue loss are classified into Rutherford grade III and categories 5 and 6, based on the significance of the tissue loss [4]. These two clinical classifications can be translated into each other according to Table 2. Fontaine Classification Rutherford Classification Stage Clinical Grade Category Clinical I Asymptomatic 0 0 Asymptomatic IIa Mild claudication I 1 Mild claudication IIb Moderate to severe claudication I 2 Moderate claudication I 3 Severe claudication III Ischemic rest pain II 4 Ischemic rest pain IV Ulceration or gangrene III 5 Minor tissue loss III 6 Major tissue loss Table 2: Classification of Peripheral Arterial Disease based on the Fontaine Classification in Comparison the Rutherford Classification In the Framingham Offspring Study, the prevalence of PAD was determined in 1554 males and 1759 females from 1995 to 1998.55 The mean age was 59 years. PAD, defined as an ankle-brachial (blood pressure) index (ABI) of ABI Severity of PAD The physician also queried the participant about symptoms of intermittent claudication using a standardized questionnaire [53]. 3.2 Local Adipose Tissue Depots 3.2.1 Variability of Adipose Tissue 3.2.1.1 Anatomy and Morphology SACK: Epicardial, mesenteric, and omental fat all share the same origin from the splanchnopleuric mesoderm associated with the gut.11 Pericardial fat (pericardial adipose tissue [PAT]) is defined as epicardial fat in all these possible locations plus paracardial fat.14 Paracardial fat is situated on the external surface of the parietal pericardium within the mediastinum and has alternatively been termed mediastinal fat.15 Paracardial fat originates from the primitive thoracic mesenchyme, which splits to form the parietal (fibrous) pericardium and the outer thoracic wall.16 Epicardial adipose tissue is supplied by branches of the coronary arteries, whereas paracardial fat is supplied from different sources including the pericardiacophrenic artery, a branch of the internal mammary.17 Lipolysis and lipogenesis have not been measured directly in human epicardial fat. Based on approximately 2-fold higher rates of lipolysis and lipogenesis in guineapig epicardial fat than other fat depots, Marchington et al18,19 proposed that EAT serves to capture and store intravascular free fatty acid (FFA) to protect cardiomyocytes from exposure to excessive coronary arterial FFA concentrations during increased energy intake and, at other times, to release FFA as an immediate ATP source for the myocardium during periods of need. Epicardial fat and the myocardium are contiguous. Islands of mature adipocytes are more frequ ent within the subepicardial myocardium of the RV than the LV13 and may act as more readily available, direct sources of FFA for cardiomyocytes. The thickness of the wall of the right atrium is about 2 mm; the left atrium, 3 to 5 mm; the RV, 3 to 5 mm; and the LV, 13 to 15 mm.20 Possibly, FFAs could diffusebidirectionally in interstitial fluid across concentration gradients from epicardial fat into the atrial and RV walls where EAT predominates and vice versa, but this process in the LV wall can be questioned because the diffusion distance is much longer. Peri-vascular adipose tissue is defined as any adipocytes, which are located close to the vascular wall and has the possibility to secret their biomarkers into the vasa vasora of the wall (see 3.2.1.2). 3.2.1.2 Secretion of Biomarkers by Adipose Tissue Adipose tissue is known to have more functions than lipid storing. Adipose tissue secrets biomarkers and serves as an endocrine organ. Beside hormones, it secrets also different inflammatory cytokines and chemokines. The amount of adipose tissue were associated to xxx, xxx, xxx (FRAMINGHAM?!). Especially peri-vascular adipose tissue like epicardial or visceral adipose tissue demonstrated higher expression of inflammatory biomarkers compared to other adipose tissue depots in the body [REF]. Beside the systemic effect of the secreted cytokines and chemokines, also a local effect/paracrine is hypothesied. Biomarkers secreted of peri-vascular adipose tissue reach over the vasa vasora of the major arteries their adventitia, media, and intima. Therefore it might be involved in the inflammatory process of atherosclerotic plaque. Further, a local effect can be thought by direct diffusion. 3.2.2 Association of Adipose Tissue to Cardiovascular Disease 3.2.2.1 Atherosclerosis 3.2.2.2 Peripheral Arterial Disease 3.2.3 In-Vivo Assessmentof Adipose Tissue 3.2.3.1 Traditional Measures * BMI and WC [54] 3.2.3.2 Imaging-based Assessment * dual energy X-ray absorptiometry (DXA) [55] * magnetic resonance imaging (MRI) [56, 57] * ultrasound [58] * multi-detector computed tomography (MDCT) [59, 60] 3.3 Framingham Heart Study 3.3.1 Historical Origin of the Framingham Heart Study Infectious diseases were prior to World War II the major burden for public health. But through a greater microbiological knowledge and improved sanitation, the morbidity and mortality of infectious disease decreased continuously. When penicillin was introduced in 1942, a dramatic reduction was made in the prevalence and incidence of infectious diseases, especially by controlling tuberculosis and pneumococcal pneumonia [REF]. Replacing infectious diseases, public health was challenged by a mounting epidemic of CVD starting in the 1940s. With World War II over the alarming rise of CVD became increasingly evident. In the United States, 30% of all men developed CVD before reaching the age sixty. The prevalence of CVD was twice of cancer by 1950 and had become the leading cause of death [REF]. Even so the available statistic data from around the world was often crude and inaccurate, it clearly demonstrated a worldwide atherosclerotic CVD problem. Furthermore there was no known treatment to prolong life and to reduce mortality. Added to these distresses was the fact that little was known about etiology, pathogenesis and epidemiology of CVD. The big gap between the enormous public health burden of CVD on the one site and the little understanding of this disease on the other site increased drastically the need for action. At this time, some believed a primary preventative approach was more promising than a search for cures [Dawber, Thomas R. (1980), The Framingham Study: The Epidemiology of Atherosclerotic Disease, Cambridge, Mass.: Harvard University Press.], while the secrets of the etiology of CVD and subsequently for treatment were not being uncovered by basic laboratory and clinical research. Some of these prevention-minded individuals occupied positions of influence and were able to translate their beliefs into actions. The key was to develop a preventive approach, where first of all the characteristics of the host and environment, which lead to the early appearance of the disease, had to be determined. In particular, preventable or modifiable predisposing factors had to be identified. If a practical preventive approach was developed, the hope was that doctors and public health officials would adopt it and so have a widespread impact on the reduction of CVD-based morbidity and mortality. Accordingly to the preventive approach, the Framingham Heart Study was designed given the charge to identify these modifiable characteristics of host and environment for CVD. 3.3.2 Initiation of the Framingham Heart Study By the mid 1940s several striking studies were conducted with an examples epidemiological approach in the fields of nutritional imbalance, metabolic disorders, occupational hazards, accidents, cancer and rheumatic fever under principle investigators (PI) Drs. Dawber, Meadors and Moore [REF, Dawber, Meadors and Moore 1951]. In common, an association between the circumstances and the disease could be identified with-out knowledge of the precise etiology. One of those studies was performed by Dr. John Snow in 1936. He demonstrated that cut-ting off the water supply from contaminated wells, despite incomplete knowledge of the pathogenesis of the disease, stopped cholera. He observed on the one hand the source of the water supply and on the other hand the time and place where the disease occurred. He sufficiently pinpointed based on his observations the major environmental factor for cholera. Further investi

Freudian Perspectives of Shakespeares Hamlet Essay -- GCSE Coursework

Freudian Perspectives  of  Hamlet  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚        Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The term consciousness refers to "one’s awareness of internal and external stimuli. The unconscious contains thoughts, memories, and desires that are well below the surface of awareness but that nonetheless exert great influence on behavior."(Weiten) The core of the Freudian perspective is centered around Hamlet’s relationship with his mother, and the relationship of Hamlet and King Claudius. According to the Freudian view, Hamlet is driven by unconscious sexual desire and aggravation. This sexual aggression is directed towards his mother and Claudius. The mystery of Shakespeare’s Hamlet is a phantom of literary debate that has haunted readers throughout the centuries. Hamlet is a complete enigma; a puzzle scholars have tried to piece together since his introduction to the literary world. Throughout the course of Hamlet, the reader is constantly striving to rationalize Hamlet’s odd behavior, mostly through the play’s written text. In doing so, many readers mistakenly draw their conclusions based on the surface content of Hamlet’s statements and actions. When drawing into question Hamlet’s actions as well as his reasons for acting, many assume that Hamlet himself is fully aware of his own motives. This assumption in itself produces the very matter in question. Take for example Hamlet’s hesitation to kill the king. Hamlet believes that his desire to kill King Claudius is driven by his fathers’ demand for revenge. If this were true, Hamlet would kill Claudius the moment he has the chance, if not the moment he knows for sure that Claudius is guilty of murdering his father. Why does Hamlet hesitate? One must call into question what Hamlet holds to be true. If Hamlet’s g... ...n personality, and that he cannot kill Claudius without killing himself. As a result Hamlet’s only solution is to die along with Claudius. Thus, by digging into Hamlet’s unconscious, his true unconscious motives have been unveiled. In overlooking the obvious, the true force behind Hamlet’s actions and inaction has been revealed, resulting in a final product that is an extensive comprehension of Hamlet’s character, and is, as Gertrude would say "more matter than art".      Works cited: Shakespeare, William.

Microwaves :: essays research papers

You might remember the heroic role that newly-invented radar played in the Second World War. People hailed it then as "Our Miracle Ally". But even in its earliest years, as it was helping win the war, radar proved to be more than an expert enemy locator. Radar technicians, doodling away in their idle moments, found that they could focus a radar beam on a marshmallow and toast it. They also popped popcorn with it. Such was the beginning of microwave cooking. The very same energy that warned the British of the German Luftwaffe invasion and that policemen employ to pinch speeding motorists, is what many of us now have in our kitchens. It's the same as what carries long distance phone calls and cablevision. Hitler's army had its own version of radar, using radio waves. But the trouble with radio waves is that their long wavelength requires a large, cumbersome antenna to focus them into a narrow radar beam. The British showed that microwaves, with their short wavelength, could be focussed ina narrow beam with an antenna many times smaller. This enabled them to make more effective use of radar since an antenna could be carried on aircraft, ships and mobile ground stations. This characteristic of microwaves, the efficiency with which they are concentrated in a narrow beam, is one reason why they can be used in cooking. You can produce a high-powered microwave beam in a small oven, but you can't do the same with radio waves, which are simply too long. Microwaves and their Use The idea of cooking with radiation may seem like a fairly new one, but in fact it reaches back thousands of years. Ever since mastering fire, man has cooked with infrared radiation, a close kin of the microwave. Infrared rays are what give you that warm glow when you put your hand near a room radiator or a hotplate or a campfire. Infrared rays, flowing from the sun and striking the atmosphere, make the Earth warm and habitable. In a conventional gas or electric oven, infrared waves pour off the hot elements or burners and are converted to heat when they strike air inside and the food. Microwaves and infrared rays are related in that both are forms of electromagnetic energy. Both consist of electric and magnetic fields that rise and fall like waves on an ocean. Silently, invisibly and at the speed of light, they travel through space and matter. There are many forms of electromagnetic energy (see diagram). Ordinary light from the sun is one, and the only one you can actually see. X-rays are another. Each kind, moving at a separate wavelength, has a unique effect on any matter it

Online retailing or E-tailing (Electronic retailing)

Online retailing or E-tailing (Electronic retailing) or direct marketing are now gaining in tremendous awareness by the businesses and the customers at large. This concept is normally termed as a B2C (business to consumer) transaction. There have been many categories or channels, which corporate adopt in order to distribute and reach its target customers.But involving and interfering with channels of a company having a multi-channel distribution system poses a great challenge. Online marketing could be done in several categories. The prominent of which are ? pure click – where in the firms sell their total products on the web based domain space or the virtual space. ? Click and Brick – They are the business which use both online and offline channel structure.Brick and Mortar – firms, which sell their entire product, line by using a physical space system. Each of these channels have their respective advantages and disadvantages, but the firm should be wise and con scious about the different channel system they are adopting as there are chances of conflicts which could arise with reference to tapping the same customer base or the same territory or having goal incompatibility.In the case mentioned, if was given a chance to be in-charge of a direct marketing system, there would be certain strategies, which I would implement, in-order to stabilize and maintain a good relation with all the other channel partners. Since there are greater chances of having conflicts between the online and offline retailers, to gain acceptance from intermediaries I would pacify or satisfy my channel partners by test marketing the following strategies and tactics.First – offer a different mix of product line or different brands on the web based system than their offline channel partners or retail partners. Second – provide better and higher discounts and commissions for its retail partner to improve the negative impact on sales and to increase the profit s. Third – Allow the customers to register their orders on the online system, but appoint retailers to deliver and collect payment where in the retailers are also cushioning on a ready-made customer base.Fourth – Give a choice to the customers if they require a work on their purchase with a financial advisor, if yes their information will be routed to an advisor. Fifth – each of the retail partners could have their own website to avoid competition of the company’s web based system. Sixth – the customers who purchase online could be allowed to accept the online coupons and redeem their amount in its stores. These are some of the ways by which I will convince my retail partners for the launch of the direct marketing campaign.
