Optical parameter Research Paper Example | Topics and Well Written Essays - 1750 words
Optical parameter - Research Paper Example This vital optics simplification does not account for the effects of optics like interference and diffraction. This paper seeks to explore the characteristics of different optical parameters. The first optical parameter is known as reflection. Different surfaces like those of mirrors reflect light in a predictable, easy way. This gives room for the production of images that are reflected which can be linked to real or virtual space location (Erik, 2004). In surfaces of this kind, the direction of the ray that is reflected is dependent to the ray that is incident to the normal surface and a line perpendicular towards the surface at exactly the same position that is hit by the ray (Francos, 2002). The reflected, and the incident ray lie in a same plane, and the angle of incidence is the same as the angle of reflection. This is referred as the reflection laws. Diagram 1 represents the incident and the reflected ray. Diagram 1. In a mirror that is flat, the reflection law means that the objectââ¬â¢s images are upright and at an equal distance behind the given mirror (Francos, 2002). The size of the image is equal to that of an object. Apart from this, the images of mirrors would be laterally inverted. The mirrors having surfaces that are curved could be modeled through tracing of the ray and the use of the reflection law at all the points on the surface. Different surfaces that are curved could focus the light having aberrations because of the shape that is diverging leading to a smeared focus in the space (Hanrahan and Krueger, 2008). For instance, mirrors that are spherical will display spherical aberrations. Mirrors that are curved produce images having a magnification either less than or greater than one. These images could be either inverted or upright. An image that is upright is considered to be virtual, and images that are inverted are real and projected on the screen. Refraction, on the other hand, happens whenever light moves through a special region w ith refraction index that is changing. One easy situation of refraction happens whenever a uniform medium with refractive index ?1 interface with another medium with a different refraction index ?2 (Duarte, 2009). In this respect, the deflection of the light ray is described by Snellââ¬â¢s law which is given by; ?1sin ?1=?2 sin ?2, where ?1 and ?2 are angles formed between the reflected and the incident ray and the normal. From the given definition of the refractive index, the speed of light would also be changing from one medium to another (Francos, 2002). This implies that v1 sin ?2= v2sin?1, where v1 and v2 are the velocities of the waves the different media. In this regard, as the rays of light travel from a material with a high refractive index to that having a low refractive index, the interface interaction could lead to a zero transmission. This is referred to as the internal reflection. Snellââ¬â¢s law could also be used in the prediction of the rays of light passing t hrough media that is linear whenever there exist a refraction index and the media geometry. Absorption is a manner in which photon energy is obtained by matter. During the propagation of a wave, absorption is referred to as attenuation (Francos, 2003). The waves of absorption do not rely on the linear absorption. In some cases, the medium may change its dependently transparency in respect to the wave intensity and saturated absorption (Duarte, 2009). The

Othello William Shakespeare Essay Example for Free
Othello William Shakespeare Essay * William Shakespeare created one of his most famous plays Othello to investigate in an influential manner the unrelenting issues of racial discrimination and gender equility. Based on the tale ââ¬ËUn Capitano Moroââ¬â¢ (The Moorish Captain) by Giovanni Cinthio, Othello was written during the epoch of 1603. Due to the actions of Othello, in the midst of a small cast, there is an exploration of sexual jealousy, and thus this play has earned a title of a domestic tragedy. * In this, the final scene depicts how the tragic hero Othello acquiesces to his incurable blemish and reaches his cessation. The foreseeable ending is cathartic for the audience to experience catharsis, as they experience a passionate feeling of trepidation and pity. Shakespeare shows how he is able to differentiate an individualââ¬â¢s personality in the unchanging hierarchy of his society. * This was achieved through the Turkish invasion in Cyprus where the Venetians fought purely for national identity. Intertwined in the play, the Machiavellian character of Iago brings a certain rise to chaos and blurs out all the lines between appearance and reality. Saying this, by Shakespeareââ¬â¢s intense use of language, the emotional engaging final scene, brings back a certain order; giving light to issues of truth, race and female insubordination and defining the central protagonist. Context: * Written between 1601 and 1604, Othelloââ¬â¢s context is based around the eras of the Elizabethan and Jacobean epochs of English history. Between the two different periods, the Renaissance ideologies are greatly encompassed. These ideologies are that of a cultural movement occurring throughout Europe in the 14th to the 17th centuries. In the crux of this era, a deep understanding of characters and issues in Othello may perhaps be attained from the initial actions of the play, being set in one of the foremost cities of the Italian Renaissance. Moreover, this period also brought with it the Protestant Reformation which was commenced by Martin Luther which viewed the refusal of medieval Christian values. The Protestant theology believed that Godââ¬â¢s divine plan of rational and moral logic was constant throughout society; one which developed in the unchallengeable hierarchy. * The Chain of Being was the reason for such order whereby it relegate all beings to ones rightful place and purpose in the universe. To preserve such a harmony, people had to develop reason and intellect to rule their emotions. In difference to such strict array, the Renaissance also gave rise to Humanism. Pico Della Mirandola here declared that ââ¬Å"one could become as low as an animal or through intellect and imagination become equivalent to God, at least in understandingâ⬠1, which I believe may have shaped Shakespeareââ¬â¢s traditional thinking in Othello. * The selection of using a black tragic hero was indeed controversial, and furthermore those ââ¬Å"Blackamoorsâ⬠in Shakespeareââ¬â¢s previous dramas were without a doubt wicked. This is exemplified through Aaron in Titus Andronicus where this drama exclaimed ââ¬ËIf one good deed in all my life I did, I do repent it to my very soulââ¬â¢(Act 5, Scene 3). Due to the conflict with Spain during the Elizabethan period, Blackamoors arrived in England and were reduced to servants or slaves. Therefore it is obvious that the audience of the era would have seen Othelloââ¬â¢s superior military position as a serve rebellion to natural order. * Nevertheless, although the importance of race in Othello, it is essential that the audience recognises that the play is created primarily for the concern with class and subordination rather than forceful racism. The historical and geographical setting also plays a major influence in bringing various amounts of symbolism to the play. Venice was seen as a locus of Christian civilisation, rational order, culture and prosperity. It was also linked with poisoning as it was the birthplace of Niccolo Machiavelli. Moreover, the city was at the forefront of the battle, between the Christians and the Turks; who were seen as malicious, barbaric infidels. * The conflict was move to the island of Cyprus in 1570 which was a place isolated from civilisation and allied with Aphrodite, the goddess of love- and thus deemed a place of wild infatuation. Therefore we can see how this setting is able to show Othelloââ¬â¢s inner conflict and dichotomy of identities; between the civilised and the barbaric, the Christian and the Pagan, the good and the evil within himself. Theme 1: Women * According to the time that the play was written in and the general hierarchy within Venetian society men hold all the power and women are considered to be of low intellect. Yet it is the women that speak the most sense throughout the play and it is also the women that are able to trust other characters in the play. Each woman represents a different social level, Desdemona being the highest and Bianca being of the lowest. Each sexual relationship in the play provokes some jealousy between the couple. * Bianca does not appear in the play as much as the other female characters yet her presence is key to the death of Desdemona as well as other play themes. Iago often refers to her as a prostitute, A house wife that by selling her desires, Buys herself bread and clothes. She has fallen in love with Cassio, yet he does not speak of his returned affection for her due to his desire for status, and her social standing would affect this dramatically. She is the jealous partner in this relationship and expresses this when Cassio produces Desdemonas handkerchief, which Iago has planted in Cassios room. * As Iagos wife and Desdemonas lady in waiting Emilia helps link Iagos plan. It was she whom supplied the Desdemonas handkerchief for Iago. This helps Iago distort Othellos views about Desdemonas fidelity. It is interesting that she does not question Iago too much when she gives him the handkerchief, it could be considered that this illustrates female ability to trust in the play. However she also remains ignorant of the entire plot until the end, when her life comes to an abrupt ending, at the hands of her husband, Iago. She often failed to think before saying and performing some action. This, without much thought, uncovers her husbands plan, but she fails to consider the consequences for herself. This is very different to her husband, who seems to plan out every word in order to get the right response. It is apparent that this is quite an unhappy marriage, made clearer through their dissimilar personalities. She has many honorable qualities such as her honesty in addition to her loyalty towards Desdemona. Iago does not treat her like his wife until he requires something; this shows this marriage was purely one in order to gain status among piers. * Throughout the play Desdemona is a symbol of innocence and helplessness. However on first encounter with her she appears to be mature and quite perceptive of events around her. Iago often tells Othello that she is unfaithful. It seems that she refuses to accept what is happening. Her views are impartial. She has a tendency to be sympathetic towards other peoples situations, like Cassio. This also further inspired Othellos jealousy when Iago pointed out they were speaking in privacy. She often pays attention to other peoples thoughts yet remains cynical if they differ to her own. She has a loyalty to her husbands in all aspects of life, whether it is mental or physical. If Desdemona had been an emotional void then Iago would not have succeeded in his plan. This would have meant that she would not have lied to Othello about losing the handkerchief, which she did so as not to hurt his feelings. However Othello sees this as an attempt to deceive him and conceal the alleged truth about her affair with Cassio. Even her final words, indicate that she blames her death on herself, and not her jealous husband. * Othello was indeed a tragedy, in which out of the three women that are introduced, only one survived. Although the women were all rational in thought and trusting, their trust was often misplaced, in gentlemen like Iago. As well as this regardless of their intellect and contemplation of events around them (in some cases) this was not enough for them to rise up in society, as women had no opinion in the time of the play. Although Shakespeare undertook many modern day ideas, he did not do this for a modern day society, as it would not have allowed so many events to occur, and it would not have been considered realistic by the viewing public. Theme 2: Appearance vs Reality. * When we are able to see the hidden truth in the closing scene of Othello, the distinct battle between appearance and reality is concluded, giving a clear exposure to the understanding of all the characters and issues of the play. Notably, productions of Othello during the Elizabethan epoch would have used a white actor as the protagonist, and masked their skin with black makeup. * This ultimately emphasises the immense difference between external appearances and the internal reality, whereby the obvious dishonesty of the white Iago is juxtaposed with a fundamentally dignified black Othello. This is further promoted by the lines of the Duke in Act 1, who confirms that ââ¬ËIf virtue no delighted beauty lack/ Your son-in-law is far more fair than blackââ¬â¢. * Iago has the ability to clearly identity the fraud of appearances; as also he is the most likely to lie, he gains a trust from all characters in the play which concludes as being fatal to Othello. Iago further says ââ¬ËI am not what I amââ¬â¢, as he is able to put on a fake honesty in society and only tells of his wickedness in soliloquy with the audience. * Thus wickedness allows Iago to affect the thinking of Othello and moreover creating a crude image that ââ¬ËCassio did topà herââ¬â¢, hence believing his obscure reasoning and logic and making Othello take this as the truth leading to his disastrous endings. The soubriquet of ââ¬Å"Honest Iagoâ⬠is continually reiterated by Othello, Cassio and Desdemona; hence it is cynically mocking those he wanted to deceive. Moreover, in the closing scene, the truth is slowly revealed as Iago is finally revealed as the villain who he is seen by the audience throughout the whole play. * Although, in the final resolution to ââ¬Ënever speak wordââ¬â¢, Shakespeare is able to penetrate the message of the very mysterious and inevitable human nature which Iago represents. Actions made by Othello are depended on the characters ability to not see things. He is able to blame and prosecute Desdemona even though he never witnessed her so called unlawful act against him, and Emilia- although she does witness Othelloââ¬â¢s extreme anger and sadness over the loss of the handkerchief- she does not properly see what her husband has done to cause this. * Thus it is obvious to see how the importance of the ââ¬Ëeyeââ¬â¢ imagery in the final scene as it helps to demonstrate a material realisation of the actual fatal truth. Once Othello has committed his own suicide, Iago is invited by Lodovico to ââ¬ËLook on the tragic loading of this bed/ This is thy work. The object poisons sight, let it be hidââ¬â¢. * Formerly, Iago poisoned Othello by pouring ââ¬Ëthis pestilence into his earââ¬â¢. Conversely, it is as though Shakespeare is parodying the heroes need for ââ¬Ëocular proof, as it ends as the eye which receives the poison; with the man himself Othello being a part of the typical ending for a Shakespearean play, a horrific massacre. We then gain an understanding from the conclusiveness of death a certain reality and moral implication on issues of truth within the final scene. * Furthermore, it is only a given that Emilia protects Desdemona as ââ¬Ëthe sweetest thing that ere did lift up eyeââ¬â¢, followed by Othello confirming his own wifeââ¬â¢s truthful innocence by declaring of her look that ââ¬ËThis look of thine will hurl my soul from heavenââ¬â¢. Hence in the closing scene of the play, Shakespeare uses both visual and auditory imagery to show the difference between appearance and reality and deepen our understanding of the character Othello. Theme 3: Order and Chaos * The final scene, due to Elizabethan context, brings to place the restitution of order; which helps to reunite the characters with concerns they have detained throughout the play. All Shakespearean plays depict a hierarchic society to maintain the cosmic laws of God. * A great amount of torment in the 17th century came from this Great Chain of Being, as a disturbance of this order possibly would force the world into great chaos, one which out does any of the kind. Othello is given two roles in this, one as the creator of chaos, and the other, the protector of order. Being held at high regard as the military general gave him the label of a hero and defender of Venetian civilisation. * However, due to his race and colour, Othello also was seen to be threatening the white authority of the state. Much the same of the island of Cyprus, Othello was colonised by Venice, and used, however never fully becomes a Venetian. * With social fears of miscegenation, Othelloââ¬â¢s position as an outsider was forced upon him, and hence by Brabantioââ¬â¢s repulsion at the harsh image of a ââ¬Ëblack ram tupping your white eweââ¬â¢. Yet, like all Shakespearean plays, order is restored in the final scene. In this scene, Othello is able to re-establish himself as a heroic soldier through his suicide, by getting rid of the barbaric Turkish enemy. Through the uses of chaos and order, it represents the battle between Christians and Infidels. In the closing scene of Othello, Emilia reiterates ââ¬Ëplay the swan/ and die in musicââ¬â¢. * This natural imagery says that it is possible that the laws of nature or religion are extremely powerful in society. This belief is further exemplified through the religious turmoil of the previous century, as Protestants were harshly persecuted under the rulings of Queen Mary I. * Thus, it is obvious how religious devotion kept world order. We can further link Othelloââ¬â¢s character to black magic and a pagan history through items such as the handkerchief, illustrating the disorder of the unknown to the Venetians. This is further linked with Christopher Marloweââ¬â¢s, Doctor Faustus who is able to create a sense of disorder through his associations with the devil. Saying this, at the ending of Othello, Shakespeare verifies that chaos and disorder can occupy the microcosm of an individual. * As Othello states ââ¬ËPerdition catch my soul/ But I do love thee; and when I love thee not/ Chaos is come againââ¬â¢, we can see how he foreshadows an expression of self chaos at the loss of Desdemonaââ¬â¢s love. Next to the ââ¬Ëtemptation sceneââ¬â¢ of Act 3, we see how Othello succumbs to the ââ¬Ëgreen eyed monsterââ¬â¢ of pure jealously brought on through Iagoââ¬â¢s evil mind games. * This extremely powerful human emotion releases the beast hidden in Othello. This can greatly be seen in the breakdown of his language which has been his tool to command order throughout the whole play; typical of his contextual authority. He cries ââ¬ËPish! Noses, ears,/and lips. Isââ¬â¢t possible? Confess-handkerchief! O/devil! ââ¬â¢, illustrating his confused mind and disorderly insecurity over Desdemonaââ¬â¢s fidelity. However, as the play closes, Shakespeare leads Othello back to person order. * In ââ¬Ëkilling himself to die upon a kissââ¬â¢, Othello is able to seal his bond with his sweet and innocent wife, Desdemona and eventually dies in an act of love. Ultimately, the final scene of Othello, illustrates to the audience the utmost importance of the restoration of order, in terms of both social structure and the individual. Conclusion: The final scene of Shakespeareââ¬â¢s Othello, offers us a sometimes erratic, emotion and foreseeable series of events. However this type of ending is extremely effective. It is in agreement with various traditional Aristotelian tragedies by the way it involves an intense feeling of pity and fear for the audienceââ¬â¢s entertainment. Moreover, the exaggerated ending of the play brings intensity and incites the readers to look upon the nature of the characters in the various issues amongst the play. Mainly, in the final scene, we see the flaws of the tragic hero, the Machiavellian disposition of Iago, the way women are seen and positioned in Shakespearian context and lastly the necessity of order after the use of chaotic dimensions. Ultimately, the various emotions and thoughts put upon the audience in this final scene of the play Othello, helps promote and illustrate how it is one of Shakespeareââ¬â¢s most intriguing and controversial plays.

Management in Multinational Corporations (MNC)
Management in Multinational Corporations (MNC) The internationalization of business activity is getting progressively essential and inevitable. Of considerably significance is thus also theà globalization of human resource management. Nowadays, anà increasing and sufficient flexibility of companies is required as well asà the ability to react to local circumstances and market constraints. Hence, in order to facilitate the process of adaptation to global developments in corporations, and especially in the Human Resourceà vicinity, a set of typologies/approaches have been developed forà Multinational Corporations (MNCs). In that case, the approaches canà be used to illustrate the strategic intent and the situation in which theà MNC is in (Hollinshead, 2010, p. 51). Accordingly, there are differentà approaches to IHRM developed by several theorists. This paperà examines four approaches, which have been developed by the USà management theorist Howard Perlmutter (1969) and by Adler andà Ghadar, with the purpose of giving an understanding to the associationà between the multinational parent in the country of origin and theà subsidiary located elsewhere. The four approaches build up inà succession by describing a trend from immature dependency ofà international subsidiaries towards mature autonomy (Hollinshead,à 2010, p. 52). These approaches have b een created to be applied toà managing and staffing the subsidiaries and constitute certain policiesà and attitudes in managing IHRM activities. Consequently, are there anyà similarities and differences between these four approaches? Discussion MNCs have to decide upon one approach to apply to the HRà activities. The best suited one can be chosen among the ethnocentric,à polycentric, regiocentric, and geocentric style. Before starting toà outline parallels and divergences, it is key to get a short overview ofà the characteristics of each approach. Firstly, the ethnocentric (alsoà called domestic) method has its focus on home market and export. Approved management techniques from the country of origin areà transferred to the operating international subsidiaries. The aim here isà to maintain the power in the home country; thus a centralizedà managerial authority comes into its own (Hollinshead, 2010, p. 52). Another trait is that cultural factors do not play a role; the foreignà cultural influence is totally ignored. As outlined by Adler and Ghadarà ( 1990:242) it is more a matter of We allow you to buy our productsà (Hollinshead, 2010, p. 55). Consequently, routine activities are carriedà out by recruited host country nationals (HCNs), while parent countryà nationals (PCNs) are in charge for the management of the subsidiaryà (Hollinshead, 2010, p.52). In polycentric (international) orientedà companies, the focus lies on local receptiveness and transfer ofà learning. The overseas subsidiaries are regarded as self-governingà business units, which are controlled and managed by HCNs, whereasà key decision making (e.g. financial investments, etc.) is still in theà responsibility of PCNs (Hollinshead, 2010, p. 54). The third method isà the regiocentric (multinational) approach, where the focal point is theà global strategy, low cost and price competition. This metho d is aà midway between the culture and the global profile. In this case, theà most effective managers get recruited regardless of their country ofà origin, thus a sharing of common organizational culture across distinctà managerial alliances take place (Hollinshead, 2010, p.54-56). The lastà approach is a geocentric (global) cultural sensitive one, where it isà concentrated on both local responsiveness and global integration. Theà aim is to establish a collaboration between the parent and theà subsidiary and again between subsidiaries (Hollinshead, 2010, p. 54-56). Eventually, these approaches, when comparing, have similaritiesà and divergences in some aspects. In the polycentric method theà primary orientation is the market and in the geocentric one theà strategy, whereas ethnocentrism concentrates on the product orà service itself and regiocentrism on the price factor. Concerning theà worldwide strategy, the ethnocentric/domestic style permits overseasà clients to purchase the product/service, the polycentric/internationalà method focuses on augmenting the market internationally and toà transfer the technology abroad, whereas the regiocentric/ multinationalà approach is looking forward to supply, market and produce the goodsà globally, and the geocentric/global approach wants to gain globalà strategic competitive advantage. Regarding the staffing of expatriates,à the international and global approach assigns many expatriates, whileà the multinational method only allocates a few expatriates and theà domestic one even none. There are also differences referring to whomà gets send. In the domestic phase it doesnt matter whom to send toà the subsidiaries (regarding the fact that almost no one is sent abroad),à in contrast the international approach assembles OK performers and sales people, whilst multinational and global approaches give attentionà to employ only very good performers as well as high potential managers and top executives. The aspect purpose varies again for the four approaches: the domestic one rewards employees when expatriating, the international approach regards expatriates as people who get the job done, in the multinational method a project and career development takes place and in the global approach a career and organizational development occurs. Furthermore, with referenc e to the career impact, in the domestic attitude, there is a negative career impact for expatriates, the international method states a deficient impact for the domestic career, which is in contrast to the multinational and global approach, where it is considered important for the global career and essential for the executive suit. For the matter of a professional re-entry, the domestic and international approaches aggravate this particular process to a great extent, whereas in the multinational and global methods it is less difficult to re-entry even professionally easy. Another facet, is the training and development (language and cross-cultural management) one, where in the domestic method no training is required and in the international approach only a time-span of one week. Quite the opposite is necessary for theà multinational and global ones, where training and development can be carried out throughout the career. Expatriates need also certain necessary skills. The ethnocentr ic approach requires technical and managerial skills, the polycentric one the same as the ethnocentric one plus cultural adaptation, the multinational one plus recognizing cultural differences and the global one plus cross cultural interaction, influence and synergy (Scullion Linehan, 2005, p. 28-29).To conclude, the four approaches can be splitted up to two blocks of approaches, by putting the domestic and international ones together in one block and the multinational and global approaches to the other block, with regard to similarities and differences. Eventually, it gets obvious that the multinational and global approaches are best suited for the globalizing market, because a change in business activities require also a change in HR policies and activities to be most efficient and effective.

The Essential Role Of Stereotype In Propaganda Essay -- Media Stereoty
The Essential Role Of Stereotype In Propaganda People encounter propaganda and stereotypes in their daily lifestyle from social interaction with peers to family and the media. Propaganda and stereotype are correlative; however their conceptual fundaments are different. Propaganda is a systematic manipulation of public opinion that is consciously disseminated to promote a doctrine or cause. Contemporary propaganda deliberately attempts to alter peoplesââ¬â¢ opinion and influence human behaviour through common broadcasters such as ââ¬Å"politicians, advertisers, journalists, and radio personalitiesâ⬠(Delwiche 2002). Stereotype is defined as ââ¬Å"a conventional, formulaic and over simplified conception, opinion or imageâ⬠(Dictionary.com 2004). These generalizations influence peoplesââ¬â¢ attitudes, values, beliefs and habits, as it conveys a biased perception towards an individual or a specific group. Stereotypes include, people conforming to a fixed image of an individualââ¬â¢s characteristics, based on race , age, gender, religion, and any other basis of subjectivity. Stereotype plays an active role in propaganda as it is publicly broadcasted to persuade the majority of people that encounter the misleading information. The tactics executed by the government in campaigns and regarding ethical dilemmas tends to be based on unsubstantiated evidence, which slanders an ethnic reputation and creates unnecessary criticisms of sexual orientation. Propaganda and stereotypes work well simultaneously, taking into account propaganda tactics are incorporated in politiciansââ¬â¢ strategy of deceiving people. Propagandists eminently use compelling arguments as a method to persuade and sway individuals opinions; contrarily, the information is misleading because it ... ...ed on March 31, 2004.

The Sundale Clubs
The Sundale Club I. Problems A. Macro 1. Division within organization due to poor relationships among personnel. 2. Lack of leadership and direction within organization. B. Micro 1. Johnsonââ¬â¢s (reputed) behavior. 2. Loss of members. 3. Chain-of-command difficulties: Frank Havens unable to talk to boss, Bob Watts uninterested in problem. 4. Poor staff morale; treatment of Pat indicates problem. II. Causes 1. No recognition/follow-through for staff. Pat overlooked for promotion. 2.Personal relationship between Chuck Johnson and Ted Ellis detracts from goals of organization and from staff morale. 3. Bobââ¬â¢s upcoming retirement detracts from interest in problems. III. Systems affected 1. Structural ââ¬â personal relationships and directorââ¬â¢s lack of interest hurt chain-of-command effectiveness. 2. Psychosocial ââ¬â low morale within staff due to favoritism, disinterest, loss of membership, lack of direction of system. 3. Technical ââ¬â none apparent. 4. Manag erial ââ¬â organizationââ¬â¢s purpose and source of money undermined by personal interests and lack of direction.Managers who had authority, such as Bob Watts, are unwilling to take action. 5. Goals and values ââ¬â there is no sense organization goals among management or staff despite declining membership. Staff and even some managers are increasingly interested in protecting their jobs or finding another job elsewhere. Consequently, there is little concern for providing service to the membership. IV. Alternatives 1. Leave as is. 2. Let Bob Watts retire; explain problem to new director. 3. Unite staff (as Carol has started); include in meeting with new director/board. 4.Carol Happ hire OD practitioner to intervene and unite staff, but this will be difficult as Watts seems to be ââ¬Å"coastingâ⬠until retirement. V. Recommendations Realistically, not much can happen until Bob Watts retires. Before Watts retires, some of the staff could unite under the leadership of C arol Happ and meet with Bob. But this has definite risks, particularly for any staff under Ted Ellis. Approach Watts from viewpoint of helping increase memberships and how unity, etc. , is needed for this to occur. If Happ and the staff can gain Wattsââ¬â¢ support, hire an external OD practitioner.

Asthma and Pollution in Phoenix, Arizona Essay Example
Asthma and Pollution in Phoenix, Arizona Essay Example Asthma and Pollution in Phoenix, Arizona Paper Asthma and Pollution in Phoenix, Arizona Paper Introduction: World Regions with accounted mild Asthma are southern Europe with 63%, Australia and New Zealand with 42%. Proportions of people with severe asthma, on the other hand, are 28% in Australia and New Zealand, 26% in Portland, 21% in United Kingdom and Republic of Ireland, both 17% in Central and Northern Europe, and 15% in souther Europe. United States has many persons with asthma cases. A research estimated that 20 million had asthma in the country (http://phoenix.about.com/cs/health/a/asthma01.htm). Though asthma, over the past 30 years, is rarely a cause of death for Americans, it had caused them an estimate of $12.7 billion in 1998 alone. Phoenix, Arizona is one of the States in America known for its concentration of asthma patients in its several asthma treatment centers. Does this conclude that living in Arizona makes people more prone to Asthma? What is the current state of its surroundings that may affect the health condition of these people? Background: Asthma is a continual lung disease. Persons living with it are suffering from coughing and shortness of breath caused by the inflammation of his airways. According to medical practitioners in the U.S. government, asthma is hereditary meaning someone that has asthma can have a close relative in the family that also has its unpleasant symptoms.à But new research suggest that being exposed to things that triggers asthma early in life may increase the chances of developing this disease(nhlbi.nih.gov/health/dci/Diseases/Asthma/). Asthma is incurable, but it could be controlled so that few and infrequent symptoms can be experienced. Asthma episodes or attacks happened when symptoms get worse than usual. Asthma attack is characterized by the tightening of airways causing airways narrower so the person experience less air intake. In addition, airways cells make more mucus intended for trapping foreign materials that flows with the air inhaled. These two actions by the body make the person hard to breathe. Severe asthma attacks could cause death because of non-delivery of renewed oxygen to vital organs such as the brain and the heart, and non-exhaustion of waste gases from the body such as carbon dioxide. In case of severe asthma attacks, an immediate medical attention is necessary. Several prescribed medicines would make the affected body of the person in control. To avoid such attacks, persons with asthma were advised to consult with his doctor regularly. Asthma is said to be one of the leading causes of children missing in school. Also, occupational asthma are said to be the most prevaling work-related lung disease in developing countries (lycos.com/info/asthmaunited-states.html). Asthma in Phoenix à à à à à à à à Two of United States top 25 cities with the highest asthma prevalence were Tucson ranking first and Phoenix, not far ranking third. Both of them come from the state of Arizona. Someone would presume based on these given data that the latter is one of the worst places for asthmatics. But this would not be the case. Before someone judges, he should first consider all factors that could contribute to these facts. Before, the State of Arizona governing the city of Phoenix had started an ambition of making its territory as a health destination. The government had permitted to build several asthma treatment centers with attractive facilities causing many asthmatics to migrate for a better living in this place. Its climate characteristics which are dry, warm and sunny made Phoenix together with the other parts of Arizona more attractive to better-health seekers. Asthmatics belonging to the middle and upper class, upon knowing this government program, had the n left their own place and inquired how to settle permanently in Arizona. Asthmatics community builds up in the area, mixed up with the local community, they get into inter-marriage, families expanded, and concentration of people with Asthma grew into Arizonaââ¬â¢s major cities. Being a city with a high concentration of asthma people, Phoenixââ¬â¢s environment and health officials closely monitors the status of its pollution. They were being alarmed with the harmful effects that were brought by the continuous industrialization in their area. Pollutionââ¬â¢s threat to Better-Health Seekers: à à à à à à à à à à à à Phoenix, Arizona is a dessert place. Any land disturbances would therefore create dust pollution that would affect its residents. According to the Arizona Republic Online Print Edition, housing construction is a factor in the constant acquiring of pollution of the south Phoenix. Together with this problem is the toxic emmissions from cars and industrial plants. The residents are concerned with the diesel-powered ââ¬Å"16-wheelerâ⬠trucks that usually drive through their residential areas. Residents are also worried if industry fires like the 2000 Central Garden Warehouse Fire and chemical spills such as the 1992 Quality Printed Circuits Fire would happen again thus endanger their health. Based on studies, diesel-fuel emmisions are more harmful to people than the regular gasoline emissions. These emissions increase the threat of worsening the condition of people with asthma, together with lung disease and heart attacks. Another r eport states the occurrence of a ââ¬Å"Brown Cloudâ⬠over the city that were said to have been caused by the discharge carbon and nitrogen dioxide gas mostly from burning fossil fuels. State Government, Residents and Industry Actions: à à à à à à à à à à à Maricopa County Air Quality Department is created in1994 to keep track and enforce air-quality standards. It had organized a seminar at the South Mountain Community College drewing 20 residents as its audience. The residents reported their claims on the current condition of their surroundingsââ¬â¢ air. Director of the Air Quality Department, Bob Kard, said everyone must contribute to the elimination of these hazardous air pollutants. He specified that South Phoenixââ¬â¢s air pollution is caused by mainly by automotive fumes, waste gases form industrial plant industries and land disturbances such as made by housing construction. Both the agency and the residents share the same sentiment of being worried for another industry accident. The county formed a sub-committee in south Phoenix, the Industry Challenge/Good Neighbor Partnership which aims to reduce the hazardous pollutants from industry emmissions by 20 percent for the next two y ears. The county also had promised they will put into action more safety measures to prevent such chemical spills at plants said to be handling delicate chemicals such as ammonia, chlorine and nitric acid. Even the above twenty companies operating in south Phoenix supports this drive by joining voluntarily into the partnership. The three sectors had all agreed to come up with cleaner air to our sorroundings as soon as possible, therefore making the city of Phoenix still a haven for better-health seekers such as those suffering from the chronic disease asthma. Is Phoenix still be a safe place for asthmatics? à à à à à à à à à à à The state government of Arizona started an initiative to protect its air. The drive was both supported by the residents and industry owners. They had all promised that in the near future, there would be an almost clean atmosphere hovering above the cities of Arizona. But environmentalist states that their actions do not suffice to meet their desired objective. One evidence environmentalist states are the persons who suggested using the plenty normal gasoline after one of the two pipelines supplying Phoenix broke last midyear of 2003 ( tinyvital.com/BlogArchives/000252.html). The two pipelines supplies Phoenix own blend of oxygenated gas, which only few refineries produce. The persons, who had gave a suggestion, unfriendly in turn point out that if the government would still prevent the use of normal gasoline, then Phoenix would face a gas shortage. Remember, there is a drive against the use of diesel because it emits more hazard than the r egular gasoline. Why do sacrifice the health of the residents so as the same residents would not suffer from the increase of gasoline prices because of its shortage? Whatever other material reasons, the government would still prioritize the health of its constituents. If it would give chance to the suggestion wether it is just for temporary resolution, then it would give an idea that the government would allow pollution just as its state would not suffer gas shortage setbacks. Healthy people would not be get affected easily but how come to those persons with asthma and other lung disease. Does the person suggest government to throw away his asthma treatment programs in exchange? Conclusion: à à à à à à à à à It is nice that Phoenix had set an ambition to be a medical destination with its asthma treatment centers. The government must continue to support the drive for not only clean air but also for clean land and clean water. à If the private sector would support their actions, then Phoenix would be a permanent haven for all better-health seekers.

andrew jackson the tyrant essays
andrew jackson the tyrant essays I cannot be intimidated from doing that which my judgment and conscience tell me is right by any earthly power. This quote by Jackson underlies the fact the he was a selfish, tyrannical ruler. He did not make decisions based on the interests of the whole nation but on his own personal benefit, in search of self- achievement. Although he was portrayed or possibly manipulated the citizens to believe that he was a president for the common man, that was simply not the way he acted. As president, he purposely ignored the power of the Judicial branch to judge laws, and strengthened the power of the Executive branch above the limits in the Constitution. He was also said to be rude and uneducated, which might have led to the reasons why he was such a power hungry tyrant; but before one makes this harsh judgment they must first realize the type of life that Andrew Jackson lived. It almost certainly was the main reason why his thought process was so different from the regular wealthy, educated earlier presidents. The third child of Irish immigrants, he joined the Army when he was only thirteen years old. Although he was young he had already developed hatred towards the British, because his oldest brother was killed fighting in the Revolution. Even though Jackson was an exceptional soldier, both him and his middle brother were captured by British troops. After their mother pleaded for their release, the boys were set free, but due to the poor living conditions of the army camp, Jacksons family was overcome by the smallpox disease. Leaving him all alone in life. This traumatic time in his life could have been the start of all his psychological problems. It seems that trouble almost always found Jackson. After being a lawyer for only a few years, an argument with another lawyer in the town led to an insult. Eventually Jackson challenged the man to a duel. Things did not look good for Jackson's oppone...

Argumentative Essay Sample on Homeschooling
Argumentative Essay Sample on Homeschooling Governments around the world usually require that parents send their children to educational institutions with trained and qualified teachers or tutors who can train the children according to a certain curriculum approved by the national government. Nevertheless, a new trend of educating children has been on the rise, which is the trend of educating children within homes. An increasing number of parents across the world seem to perceive it is much better for their children to be educated within their homes, by teachers selected by the parents, to offer customized education to their children. Most of the parents who prefer homeschooling are those who do not feel like the quality of education offered in educational institutions is good enough and does not deeply cover the curriculum, as the parents prefer. There are many reasons why a parent may prefer homeschooling to education in schools, such as social factors. Educational institutions have been plagued by numerous social problems such as bullying and antisocial behavior. To prevent their children from being bullied or being pressured into uncouth behavior by peers, some parents have made it their duty to supervise the company with which their children interact, and homeschooling provides the best environment that enables the parents to pay close attention to the social behavior of their children. The quality of schooling that educational institutions offer is another reason that pushes some parents to prefer homeschooling. Many schools are not strict on the number of students allowed in each class, and this has resulted in a situation where some schools have classes with too many students per class. When the students in a class are many, the teacher may not have enough interaction with each one of the students and as such, may even miss identifying any special needs that a student may have. Some educational institutions are also never given enough funds to operate and this easily results in a situation where teachers may not have enough tools to teach the students. In other cases, the teachers may even be demoralized, due to the lack of sufficient resources, and this can easily affect the way the teachers teach the children in class. Parents who select homeschooling never worry about such issues, because they get to pay the teachers nicely and also offer all the teaching tools needed. Yet, another reason for homeschooling is to offer the children subjects or units that may not be offered in educational institutions that are accessible to the parents. For instance, a parent may want their children to access certain religious classes together with the normal curriculum. If the parent cannot find a school that will offer those extra classes, a parent may decide to home school their children and offer their children the customized education.

Scanning the Environment DB - Essay Example However, people may typically not want to compromise too much on cost for food items. These socio-economic trends in population has resulted in Aldi's strategy for high quality and low cost food products. The amount of television and internet advertisements for their respective products from Amazon and Aldi's will be a part of the marketing strategy of these companies. The target customer segments, their demographics and behavioral trends will determine the mode and volume of television and internet advertisements. It can be observed that the people having obesity problems tend to live a sedentary lifestyle with more number of hours in front of televisions or computers. No such observation can be made for target customers for high quality foods. Hence, in case of Amazon the amount of television and internet advertisements will be more as compared to Aldi's. While both, Amazon and Aldi's may have their advantages and disadvantages, considering their strategies, Amazon seems to be better positioned than Aldi's. The main reason for this being focused on a particular target customer segment i.e.

Is the ceation of israel justified Essay Example | Topics and Well Written Essays - 2500 words
Is the ceation of israel justified - Essay Example This did not go well with the Arabs and this is the contributing factor in the instability in the Middle East. Both the Israeli and the Arabs maintain that they have a valid reason to own their present occupied land with many controversies on the ownership of the Gaza strip and West bank. The Israeli, on the other hand, have decided to partition their territory, which the Palestine strongly feels, is a serious encroachment into their land, this is following increased bombing attacks from the Palestine part. On the other hand, the Palestinians have strongly opposed the construction of the partition wall claiming that its construction will hinder their itinerary across the land and have appealed to the UN to stop the construction. Even with the persistent war over the ownership of the contested territories, there have been numerous unsuccessful attempts to find a solution diplomatically to the problem in the Middle East. but the non-cooperating partners have frustrated them when it com es to compromising for a solution to be realized. The Perspective of the Israeli on the Formation of the Jews State The Jews strongly believed that the formation of the Israeli state was justified and that they deserved it. ... s are used by the Jews to assert their occupation of the Israeli State; The Holocaust This is one of the justification that the Jews are using to explain their logics behind the creation of the Israeli state. The holocaust was a period immediately before the outbreak of the Second World War; it was presided by the Germany dictator, Adolf Hitler and his Nazi Party. During this time, approximately six million Jews were murdered in one of the worst genocides in the world history. The Jews faced opposition by the Germans and through the order given by Hitler, they were supposed to be eliminated and wiped out of existence. This mass murder witnessed about two-thirds of the nine million Jews in Europe murdered, in the breakdown of the persecution; about one million children, two million women, and three million men of the Jews origin were killed in the systematic state sponsored killing. Because of the unbearable situation in Europe, the Jews had no option but to consider going back to the land they occupied long time but the Arabs then occupied it. In order to realize this, they used the British presence in the Middle East to make a comeback after fleeing the widespread persecution that was ordained by Hitler in Europe. For the Jews going back to occupy the present Israel State is thus a case of going back to occupy a land that they had abandoned. Given the fact that even the Arabs (the Palestinian) in the land are also not the true owners of the land, they claim that there is no better squatter than the other is. They believe that just as the Arabs have the right to live in the area, they also have equal right. They previously occupied the land before scattering all over the world, and the Israeli use this to delegitimize the claims by the Arabs that they have invaded the
Motivation Methods Paper Essay Example | Topics and Well Written Essays - 1250 words
Motivation Methods Paper - Essay Example This can be done through a needs analysis or even qualitative research such as interviews or questionnaires to determine the real-life attitudes of employees. Motivating employees requires a blend of transformational leadership development, experiential learning, negotiation strategies, and making appeals to psychological needs. Many organizations that operate in dynamic and ever-changing environments must be flexible and adaptable in order to maintain its competitive edge and advantages over other businesses operating in the same industry. For some businesses, marketing and promotion are critical dimensions that differentiate the brand or the product from other companies selling similar products in multiple domestic and international markets. In order to be adaptable, change management becomes critical. According to Grieves (2010, p.8), ââ¬Å"change is a negotiated orderâ⬠, where internal stakeholders of all varieties attempt to exert persuasive influence on others in order to achieve goals and objectives established by the organization. In order to motivate employees in an environment where there is considerable resistance to change, the manager must consider bargaining tactics in order to negotiate these changes. Employees who often resist change can reduce productivity and complicate the development of special projects that are critical to achieving corporate goals and gaining competitive edge. In many scenarios, such resistance is caused by negative sentiment or attitude about the change and its potential impact on job role and responsibilities. Employees are more willing to accept change activities and principles when they feel they have been given an opportunity to express their concerns about the activities and the potential risks employees feel the change imposes. If employees do not feel they have been given adequate decision-making authority and are being heard by management, they will not feel appreciated within the organizational context. Thu s, the manager should attempt to create a sense of social belonging and also build self-esteem in employees associated with the change. According to Morris & Maisto (2005), these are fundamental human behavioral needs that are critical to achieving a self-actualized, motivated attitude about job role achievement. The most effective methods of establishing motivation in a changing environment are to bargain the change imperatives and ensure that consensus becomes part of the management model. Another method of improving motivation in the organization is the development of the transformational leadership style. According to Fairholm (2009), transformational leadership is a human resources-based management system whereby the manager works as a teacher, mentor and coach to others in order to build their competencies and individual skill-sets. A transformational leader also imparts vision and mission on others in the business, role modeling ethical behaviors to build trust between subord inate and manager. In organizational environments where there are traditional management models that have rigid control systems and reward systems that are contingent on performance in job role, employees are not given opportunities to express their creativity or achieve autonomy in job role. Transactional leadership, as one example, is a management philosophy where goals are

Persuasion Essay Example | Topics and Well Written Essays - 1000 words - 1
Persuasion - Essay Example Emphasizing this particular issue, the objective of the essay is to develop an overview about the nature of message delivered through articles referred. Furthermore, in this essay, classification of the articles titled ââ¬Å"Tough love for fat people: Tax their food to pay for healthcareâ⬠by Healy (2009), ââ¬Å"Should fattening foods be taxed?â⬠by Cafferty (2009) and ââ¬Å"Americans against Food Taxesâ⬠by SourceWatch (2011) is done respectively, depending on the writing styles and the effects that they could generate on the common people. The major strength that could possibly be noted from the article titled ââ¬Å"Americans against Food Taxesâ⬠is the groupââ¬â¢s focus on the reaction of the common people regarding food taxes induced on government defined ââ¬Å"unhealthy foodsâ⬠(SourceWatch, 2011). Similarly, the articles titled ââ¬Å"Tough love for fat people: Tax their food to pay for healthcareâ⬠and ââ¬Å"Should fattening foods be taxed?â⬠can be treated as informative sources reflecting on the ways general people are bound to suffer for such taxation, especially those who are not obese; thus, offering a contradictory point of view to the issue (Cafferty, 2009; Healy, 2009). The article by SourceWatch (2011), provides a clear indication of the ways the group, i.e. Americans against Food Taxes are supporting the people combating against food taxation, which might in turn, serve as an emotional base for the popularity of the article. As can be observed, the major strength of this articl e have been to draw attention of its readers towards aspects, which might be left overlooked when interpreting both the pros and cons of the issue concerning tax imposition on ââ¬Å"unhealthyâ⬠foods. One of the key weaknesses of the article by SourceWatch (2011) is its focus on unveiling the arguments made by the Americans against Food Taxes group, funded by renowned beverage companies in the US.

Competition Act Case Essay Example for Free
Competition Act Case Essay In a telling judgement, the Supreme Court of India, on Sep. 9, 2010, has effectively and judiciously circumscribed the boundaries of exercise of power by both the Competition Commission of India (CCI/Commission) and the Competition Appellate Tribunal (ââ¬Å"the Tribunalâ⬠) while delivering its verdict in the much awaited case Competition Commission of India v. Steel Authority of India Ltd. This Note captures the highlights of the decision for readers of this Blog! Background: The Court was hearing an appeal by the CCI against the order dated Feb. 15, 2010 of the Tribunal in Steel Authority of India Ltd. v. Jindal Steel Power Ltd. Jindal Steel had filed a complaint before CCI alleging anti-competitive practices and abusive behaviour by SAIL while it entered into an exclusive supply agreement with Indian Railways. Upon receipt of the complaint/information, CCI issued notice to SAIL to furnish certain information for within two weeks from the date of receipt of such notice. SAIL requested for an extension of time upto six weeks to file the required information. CCI in its meting deliberated on the request and decided not to grant any further extension. In the said meeting CCI also formed a prima facie opinion on the existence of the case and directed the Director General (DG) to inquire into the matter pursuant to its powers under Section 26(1) of the Competition Act, 2002 (ââ¬Å"the Actâ⬠). SAIL challenged this direction before the Tribunal claiming that CCI could not have formed a prima facie opinion without hearing it first. SAIL also contended that CCI has not recorded any reasons while forming the prima facie opinion and that the time provided by CCI to file information was grossly inadequate. While filing the appeal before Tribunal, SAIL did not implead CCI as a party. CCI thus filed an application before Tribunal for impleading itself as a necessary and proper party and also assailed the very maintainability of appeal. The Tribunal, in its detailed order, holding that even the direction to inquire was appealable under Section 53A(1) of the Act noted that CCI could not have directed the DG to inquire into the complaint without having heard SAIL. It further noted that CCI was neither a necessary nor a proper party in appeals filed by an aggrieved party before the Tribunal. The Tribunal also noted that CCI did not record any reasons while declining to grant extension of time and hence it in violation of principles of natural justice. Appeal before the Supreme Court: Aggrieved by the order of the Tribunal, CCI approached the Supreme Court which framed six broad issues noting some of the allied issues raised by the parties: (i) Whether the direction passed by the Commission u/s. 26(1) of the Act while forming prima facie opinion would be appealable u/s/ 53A(1) of the Act? (ii) What is the scope of the power vested with Commision u/s. 26(10 of the Act and whether parties including the informant and other affected parties are entitled to notice at the stage of formation of prima facie opinion? (iii) Whether the Commission would be necessary or at least a proper part in proceedings before the Tribunal? (iv) At what stage and in what manner the Commission can exercise its powers u/s. 33 of the Act while passing interim orders? (v) Whether it is obligatory for the Commission to record reasons while forming prima facie opinion? (vi) What directions, if any, need to be issued by the Court for ensuring proper compliance of the procedural requirements while keeping in mind the scheme and object of the Act? The Verdict: Issue 1: The Court made an exhaustive study of the scheme and the provisions of the Act and rules of statutory interpretation, noted the distinction between ââ¬Å"andâ⬠and ââ¬Å"orâ⬠, referred to Indian, UK and European decisions to unearth settled principles of law and finally concluded that Section 53A(1) of the Act expressly provides for what decisions or orders or directions may be appealed before Tribunal. The Court noted that right to appeal is a substantive right which derives its legitimacy from the operation of law or statute. If the Statute does not provide for an appeal, the Court cannot presume such right. The direction to cause an investigation into a matter is passed under Section 26(1) of the Act does not determine any right or obligation of the parties to the lis. It does not find mention in Section 53A(1) of the Act and hence, the Court found that such orders would not be appealable under the Act. Issue 2 and 5: The Court noted that the exclusion of principles of natural justice (PNJ) is a well known concept and the legislature has the competence to enact such laws. Whether the exclusion of application of PNJ would vitiate the entire proceedings would depend upon the nature and facts of every case in the light of the Act or Rules and Regulation applicable to the case. The Court, then, read into various provisions of the Act and the Competition Commission of India (General) Regulations, 2009 in order to determine the nature of functions of the Commission under various provisions. The Court found that at the face of it, the exercise of power u/s. 26(1) of the Act while forming prima facie opinion is inquisitorial and regulatory. It held that while forming prima facie opinion, the Commission does not condemn anyone. This function is not adjudicatory in nature but merely administrative. This function is in the nature of preparatory measures in contrast to the decision making process and hence right of notice of hearing is not contemplated u/s. 26(1) of the Act. On the issue of reasons to be recorded at the stage of forming prima facie opinion, the Court held that the Commission must express its mind in no uncertain terms that it is of the view that prima facie case exists. Such opinion should be formed on the basis of the records, including the information furnished and reference made to the Commission. The reasons may not be in detail but there must be minimum reasons substantiating the view of the Commission. Issue 3: The Court reiterated the settled position of law relating necessary party and proper party. A necessary party is one without whom no order can be made effectively whereas a proper party is one in whose absence an effective order can be made but whose presence is necessary for a complete and final decision on the question involved in the proceeding. Applying the principle of dominus litus, the Court then noted that in cases where the Commission initiates a proceedings suo moto it shall be the proper party. In all other proceedings, it shall be a necessary party. Issue 4: On powers of the Commission u/s. 33, the Court noted in following terms: ââ¬Å"During an inquiry and where the Commission is satisfied that the act is in contravention of the provisions stated in Section 33 of the Act, it may issue an order temporarily restraining the party from carrying on such act, until the conclusion of such inquiry or until further orders without giving notice to such party, where it deems it necessary. This power has to be exercised by the Commission sparingly and under compelling and exceptional circumstances. The Commission, while recording a reasoned order inter alia should : (a) record its satisfaction (which has to be of much higher degree than formation of a prima facie view under Section 26(1) of the Act) in clear terms that an act in contravention of the stated provisions has been committed and continues to be committed or is about to be committed; (b) It is necessary to issue order of restraint and (c) from the record before the Commission, it is apparent that there is every likelihood of the party to the lis, suffering irreparable and irretrievable damage or there is definite apprehension that it would have adverse effect on competition in the market.â⬠Issue 6: One of the major outcomes of the case relates to the Courtââ¬â¢s recognition and affirmation of the expeditious disposal of complaints filed before the Commission. The Court found this to be a fit case to issue certain guidelines in the larger interest of the justice administration. These directions weigh special worth in the light of the fact the Commission, even after more than one year of the enforcement of the operative provisions of the Act, has not issued its order in a single contentious case. The Court passed following guidelines: (a) Even though the time period for forming prima facie opinion by the Commission is provided in the Regulations (i.e. 60 days from the date of filing information) it is expected of the Commission to hold its meetings and record its opinion about existence or otherwise of a prima facie case within a period much shorter than the stated period. (b) All proceedings including investigation and inquiry by the Commission/DG must be completed expeditiously while securing the objectives of the Act. (c) Wherever during the course of inquiry the Commission exercises its jurisdiction to pass interim orders, it should pass a final order in that behalf as expeditiously as possible and in any case not later than 60 days. (d) The reports by the Director General u/s. 26(2) should be submitted within the time as directed by the Commission but in all cases not later than 45 days from the date of passing of directions in terms of Section 26(1) of the Act. (e) The Commission/DG shall maintain complete confidentiality as envisaged u/s. 57 of the Act and Regulation 35 of the Regulations. Wherever the ââ¬Ëconfidentialityââ¬â¢ is breached, the aggrieved party certainly has the right to approach the Commission for issuance of appropriate directions in terms of the provisions of the Act and the Regulations in force. Reading between the Lines: The verdict of the Apex Court bears immense significance given the timing of and issues involved in the judgement. It may be noted that both ââ¬Å"competition law and policyâ⬠and the Commission are at a very nascent stage within the broad regulatory matrix of Indian economy. The judgement of the Supreme Court has rightly echoed the sentiments of proponents of free and fair market economy and it shall go in long way to effective sketch the competition law landscape in the country. At this point, I would like draw some conclusions which may not seem apparent at the face of it. They are as follows: (i) The Court, in its opening paragraphs, notes the importance of competition law and policy for any free market economy referring to three types of efficiencies: i.e. allocative, productive and dynamic. The Court observes that the main objective of competition law is to promote economic efficiency using competition as one of the means of assisting the creation of market responsive to consumer preferences. While it may be too early to conclude, but this certainly indicates that Indian Courts are going to lean towards Chicago School of Thought in the Chicago-Harvard dichotomy. It is the Chicago School of Economists which has brought the efficiency test as a dominant factor in last three decades in US Courts. (ii) While highlighting the aims of competition law, the Court makes a mention of the relevant laws of other jurisdictions including that of USA, UK and Australia. It would not be far-fetched to argue that the Court has indirectly hinted that in future, it shall definitely take into account the competition law jurisprudence developed in these jurisdictions while deciding contentious issues. That the Supreme Court is going to rely on EU and US Court decisions while explaining the substantive concepts involved in competition law is further strengthened by the fact that the Court referred to two decisions EU courts i.e. CFI and ECJ in its very first judgement related to the new Act even when there was no substantive concept of competition law as such involved. Remarks: (i) The Court has very effectively defined the ambit and scope of the powers of the Commission and the Tribunal at the stage of forming of prima facie opinion. No jurisdiction generally allows challenging the direction passed by the competition authorities to initiate investigation. However, there may be cases where the amount of information to be filed would be voluminous and the Commission in such cases must provide adequate time. It is doubtful whether a person would be able to challenge the denial of extension of time by the Commission in such cases. (ii) In larger interest of justice administration, the Court passed certain directions till the Commission formulates its own regulations in that regard. Though such a step by the Court is quite welcome, but the timelines provided by the Court are quite unreasonable and strict. For example, the Court has directed that the DG must submit its report within 45 days u/s. 26(2) of the Act. This seems quite onerous to be implemented in practice. The collection of evidence and ascertainment of facts would require the DG to issue notices to relevant parties. Such parties would have to prepare their responses which they intend to file before DG. All this may not be done within 45 days of time period. (iii)Though I fully agree with the Courtââ¬â¢s reasoning as to why Commission needs to give notice to parties at the time of forming prima facie opinion; the analysis seems to be incomplete as the judgement has not even referred to provisions of Section 36 of the Act. The Court should have analyzed the provisions of Section 36 while discussing the issue of compliance or non-compliance of PNJ. (iv)Finally, the Court also states that ââ¬Å"as far as American law is concerned, it is said that the Sherman Act, 1890, is the first codification of recognized common law principles of competition law.â⬠I do not want to sound picky, but to my limited knowledge, Canada was the first country to enact its Competition Act which was one year prior to the Sherman Act i.e. in 1889.

Engine Failure Of Flight 191 Engineering Essay
Engine Failure Of Flight 191 Engineering Essay The loss of the engine by itself should not have been enough to cause the accident.[12] Flight 191 would have been perfectly capable of returning to the airport using its remaining two engines, as the DC-10 is capable of staying airborne with any single engine out of operation. However, several other factors combined to cause a catastrophic loss of control. The engine separation had severed the hydraulic lines that controlled the aircrafts leading-edge wing slats (retractable devices that decrease a wings stall speed during takeoff and landing). The damage to the lines caused a loss of hydraulic pressure, which in turn led to uncommanded retraction of the outboard slats in the left wing.[1] Unlike other aircraft designs, the DC-10 did not include a separate mechanism to lock the slats in place.[1] Investigators examined the flight data recorder (FDR) and conducted wind tunnel tests and flight simulator tests to understand the trajectory of flight 191 after the engine detached and the slats retracted. These tests established that the damage to the wing leading edge and retraction of the slats increased the stall speed of the left wing from 124kt to 159kt.[1] Comparison of the FDR data and the simulator tests showed that the pilots of flight 191 had followed the procedure for engine failure at take-off. This procedure called for the captain to go to VHYPERLINK http://en.wikipedia.org/wiki/V_Speeds#Other_reference_speeds2 (standard safety takeoff speed) which for flight 191 was 153kt, 6kt below the stall speed.[1] At the time the engine fell off the aircraft, flight 191 was already travelling at 165kt, safely above the stall speed. Thus, by slowing the aircraft to 153kt in accordance with the emergency procedure, the pilots inadvertently induced the stall which proved fatal. Following this accident, McDonnell Douglas revised the procedure, advising that if the aircraft was already flying faster than V2 plus 10kt the pilots should maintain a margin of 10kt above V2.[1] The DC-10 incorporates two warning devices which might have alerted the pilots to the impending stall: the slat disagreement warning light which should have illuminated after the uncommanded retraction of the slats, and the stall warning system (stick-shaker) which activates close to the stall speed. Unfortunately, both of these warning devices were powered by an electric generator driven by the no. 1 engine; following the loss of that engine, they both became inoperative.[1] [edit] Engine separation An FAA diagram of the DC-10 engine and pylon assembly indicating the failed aft pylon attach fitting. From an examinaton of the detached engine, the NTSB concluded that the pylon attachment had been damaged before the crash.[1] Investigators looked at the planes maintenance history and found that its most recent service was eight weeks before the crash, in which engine number one had been removed from the aircraft, however the pylon, the rigging holding the engine onto the wing, had been damaged during the procedure. The original procedure called for removal of the engine prior to the removal of the engine pylon, but American Airlines had begun to use a procedure that saved approximately 200 man-hours per aircraft and more importantly from a safety standpoint, it would reduce the number of disconnects (i.e., hydraulic and fuel lines, electrical cables, and wiring) from 72 to 27.[1] The new procedure involved mechanics removing the engine with the pylon as one unit, rather than the engine, and then the pylon. A large forklift was used to support the engine while it was being detached from the wing a procedure that was found to be extremelly difficult to execute successfully, due to difficulties with holding the engine assembly straight while it was being removed. The field service representative from the manufacturer, McDonnell-Douglas, said it would not encourage this procedure due to the element of risk and had so advised American. However, McDonnell-Douglas does not have the authority to either approve or disapprove the maintenance procedures of its customers.[1] The accident investigation also concluded that the design of the pylon and adjacent surfaces made the parts difficult to service and prone to damage by maintenance crews. The NTSB reported that there were two different approaches to the one-step procedure: using an overhead hoist or using a forklift. United Airlines used a hoist; American and Continental Airlines used a forklift. According to the NTSB, all the cases wherein impact damage was sustained and cracks found involved the use of the forklift.[1] Under the procedure American used, if the forklift was in the wrong position, the engine would rock like a see-saw and jam against the pylon attachment points. The forklift operator was guided by hand and voice signals; the position had to be spot-on or could cause damage. Management was aware of this. The modification to the aircraft involved in Flight 191 did not go smoothly. Engineers started to disconnect the engine and pylon, but changed shift halfway through. When work continued, the pylon was jammed on the wing and the forklift had to be repositioned. This was important evidence because, in order to disconnect the pylon from the wing, a bolt had to be removed so that the flange could strike the clevis. The procedure used caused an indentation that damaged the clevis pin assembly and created an indentation in the housing of the self-aligning bearing, which in turn weakened the structure sufficiently to cause a small stress fracture. The fracture went unnoticed for several fligh ts, getting worse with each flight. During Flight 191s takeoff, enough force was generated to finally cause the pylon to fail. At the point of rotation, the engine detached and was flipped over the top of the wing. [edit] Conclusion The findings of the investigation by the National Transportation Safety Board (NTSB) were released on December 21, 1979:[1] The National Transportation Safety Board determines that the probable cause of this accident was the asymmetrical stall and the ensuing roll of the aircraft because of the uncommanded retraction of the left wing outboard leading edge slats and the loss of stall warning and slat disagreement indication systems resulting from maintenance-induced damage leading to the separation of the No. 1 engine and pylon assembly at a critical point during takeoff. The separation resulted from damage by improper maintenance procedures which led to failure of the pylon structure. Contributing to the-cause of the accident were the vulnerability of the design of the pylon attach points to maintenance damage; the vulnerability of the design of the leading edge slat system to the damage which produced asymmetry; deficiencies in Federal Aviation Administration surveillance and reporting systems which failed to detect and prevent the use of improper maintenance procedures; deficiencies in the practices and communications among the operators, the manufacturer, and the FAA which failed to determine and disseminate the particulars regarding previous maintenance damage incidents; and the intolerance of prescribed operational procedures to this unique emergency. The NTSB determined that the damage to the left wing engine pylon had occurred during an earlier engine change at the American Airlines aircraft maintenance facility in Tulsa, Oklahoma on March 29 and 30, 1979.[1] The evidence came from the flange, a critical part of the pylon assembly. [edit] Aftermath First responders survey the Flight 191 crash site in Des Plaines, Illinois. Problems with DC-10s were discovered as a cause of the accident, including deficiencies in both design specifications and maintenance procedures which made damage very likely. In response to this incident, American Airlines was fined by the United States government $500,000 for improper maintenance procedures[12]. Two weeks after the accident, on June 6, the FAA ordered all DC-10s to be grounded until all problems were solved. The ban was lifted on July 13.[13] The crash of another DC-10 in November 1979, Air New Zealand Flight 901, would only add to the DC-10s negative reputation at the time however, Flight 901 was caused by several human and environmental factors not related to the airworthiness of the DC-10, and the aircraft was later completely exonerated in that accident. Although McDonnell Douglas employees participated in an Im proud of the DC-10 campaign, the companys shares fell more than 20% following the crash of Flight 191. In 1997, the McDonnell Douglas company was taken over by its rival, Boeing. Despite the safety concerns, the DC-10 went on to outsell its closest competitor, the Lockheed L-1011 TriStar, by nearly 2 to 1. This was due to the L-1011s launch being delayed, the introduction of the DC-10-30 long range model without a competing TriStar variant, and the DC-10 having a greater choice of engines (the L-1011 was only available with Rolls-Royce engines, while the DC-10 could be ordered with General Electric or Pratt HYPERLINK http://en.wikipedia.org/wiki/Pratt__WhitneyHYPERLINK http://en.wikipedia.org/wiki/Pratt__Whitney Whitney engines). The DC-10 program also benefited from obtaining a U.S. Air Force contract to develop a long-range refueller, which culminated in the KC-10 Extender. Lockheed had no such support for the TriStar, and halted production in 1982. NTSB investigation The crash of flight 191 brought fierce criticism from the media because it was the fourth fatal accident involving a DC-10 at the time. Six hundred and twenty-two people had died in DC-10 accidents, including flight 191. As the weather was perfect for flying and there was no indication that a flock of birds or another plane caused the crash, the remains of engine #1 raised serious concerns of the safety of the DC-10. The separated engine was not the only concern, as the public wanted to know whether the detached engine was the only cause of the crash. Investigators wondered if a fire was possibly the cause, as this was backed up by testimony from air traffic controller Ed Rucker who said he saw a flash from the wing. This raised concerns that 191 was the result of a terrorist attack. Sixty witnesses who saw the plane on the runway ruled out a bomb, as they all saw engine #1 swing forward then flip up and over the top of the wing, which pointed to structural failure as the cause. The findings of the investigation by the National Transportation Safety Board (NTSB) were released on December 21, 1979. It revealed the probable cause to be attributable to damage to the left wing engine pylon that occurred during an earlier engine change at American Airliness aircraft maintenance facility in Tulsa, Oklahoma on March 29 and 30, 1979. cite web |url=http://amelia.db.erau.edu/reports/ntsb/aar/AAR79-17.pdf |title=NTSB (National Transportation Safety Board) Report] Evidence came from the flange, a critical part of the pylon assembly. It was revealed to be damaged before the crash, and investigators looked at the planes maintenance history and found it was serviced eight weeks before the crash. The pylon was damaged due to an ill-thought-out engine removal procedure. The original procedure called for removal of the engine prior to the removal of the engine pylon. To save time and costs, American Airlines, without the approval of McDonnell Douglas, had begun to use a faste r procedure. They instructed their mechanics to remove the engine with the pylon all together as one unit. A large forklift was used to support the engine while it was being detached from the wing. This procedure was extremely difficult to execute successfully, due to difficulties with holding the engine assembly straight while it was being removed. This method of engine-pylon removal was used to save man hours and was encouraged despite differences with the manufacturers specifications on how the procedure was supposed to be performed. The accident investigation also concluded that the design of the pylon and adjacent surfaces made the parts difficult to service and prone to damage by maintenance crews. According to the History Channel,cite video title = The Crash of Flight 191 url = http://store.aetv.com/html/product/index.jhtml?id=71451 publisher = The History Channel publisherid = AAE-71451 medium = DVD] United Airlines and Continental Airlines were also using a one-step procedure. After the accident, cracks were found in the bulkheads of DC-10s in both fleets. The procedure used for maintenance did not proceed smoothly. If the forklift was in the wrong position, the engine would rock like a see-saw and jam against the pylon attachment points. The forklift operator was guided by hand and voice signals; the position had to be spot-on or could cause damage, but management was unaware of this. The modification to the aircraft involved in flight 191 did not go smoothly; engineers started to disconnect the engine and pylon but changed shift halfway through; when work continued, the pylon was jammed on the wing and the forklift had to be re-positioned. This was important evidence because, in order to disconnect the pylon from the wing, a bolt had to be removed so that the flange could strike the clevis. The procedure used caused an indentation that damaged the clevis pin assembly and created an indentation in the housing of the self-aligning bearing, which in turn weakened the structure sufficiently to cause a small stress fracture. The fracture went unnoticed for several flights, getting worse with each flight that the plane had taken. During flight 191s takeoff, enough force was generated to finally cause the pylon to fail. At the point of rotation, the engine detached and was flipped over the top of the wing. The loss of the engine by itself should not have been enough to cause the accident. During an interview on Seconds From Disaster, Former NTSB investigator Michael Marx mentioned there were other incidents where the engine fell off, yet they landed without incident. Flight 191 would have been perfectly capable of returning to the airport using its remaining two engines, as the DC-10 is capable of staying airborne with any single engine out of operation. Unfortunately, several other factors combined to cause a catastrophic loss of control. The separation of the engine severed electrical wiring and hydraulic lines which were routed through the leading edge of the wing. The damage to the lines caused a loss of hydraulic pressure, which in turn led to uncommanded retraction of the outboard slats in the port wing. The DC-10 design included a back-up hydraulic system which should have been enough to keep the slats in place; however, both lines are too close together, a design also used on the DC-9. There should have been enough fluid to keep the slats extended, so investigators wanted to know why they were never re-extended by the pilot. The answer came from the end of the recording on the CVR. The number 1 engine powered both the recorder and the slat warning system, which left the pilot and co-pilot with no way of knowing about the position of the slats. Investigators examined the FDR to see what occurred after the engine detached. The procedure called for the captain to go to V2 which he did perfectly, but investigators found that it said nothing about incidents where the speed was already above V2, as it was in this case. Therefore, the pilot had to reduce speed. Simulator tests were done to see if this made a difference; 13 pilots followed the procedure 70 times and not one was able to recover. The NTSB concluded that reducing speed when the slats are back may actually have made it more difficult for the pilot to recover control of the aircraft. When a DC-10 is about to stall it gives two warnings: The first is the stick-shaker which causes the yoke to vibrate, and the second is a warning light that flashes. These combined warnings should have alerted the pilots to increase speed immediately. American Airlines had chosen to have the stick-shaker on the pilots side only, but the stick-shaker did not operate because it was powered by the missing left engine. In the event of an engine failure, it is possible for the flight engineer to switch the pilots controls to a backup power supply. However, inv estigators determined that in order for him to access the necessary switch, the engineer would have had to unfasten his seat belt, stand up, and turn around. The DC-10 hit the ground with a bank of 112Ãâà °, and at a nose-down attitude of 21Ãâà °. The NTSB concluded that given the circumstances of the situation, the pilots could not be reasonably blamed for the resulting accident. In his book Blind Trust, [cite book | title = Blind Trust | last=Nance | first=John J. | authorlink=John J. Nance | publisher = William Morrow Co | isbn = 0-688-05360-2 | year = 1987] John J. Nance argues that the 1978 Airline Deregulation Act caused havoc and induced cost-cutting in the industry, producing a serious erosion of the margin of safety for passengers. Nance argues that the industry reverted from an industry under partial surveillance to an industry running on the honor system. Aftermath Problems with DC-10s were discovered as a cause of the accident, including deficiencies in both design specifications and maintenance procedures which made damage very likely. Since the crash happened just before a Western Airlines DC-10 crashed in Mexico City and five years after a Turkish Airlines DC-10 crashed near Paris, the FAA quickly ordered all DC-10s to be grounded until all problems were solved. The result of the problem-solving was an arguably more efficient and safe DC-10. The US government fined American Airlines $500,000 for improper maintenance procedures, but the insurance settlement for the replacement of the aircraft gave American Airlines $25,000,000 beyond the amount of the fine.Fact|date=June 2007 Although the companys employees participated in an Im proud of the DC-10 campaign, McDonnell Douglas shares fell more than 20% following the crash of Flight 191. The DC-10 itself had a bad reputation, but ironically it was often caused by poor maintenance procedures, and not design flaw. In 1997 the McDonnell Douglas company was taken over by its rival, Boeing, which moved its corporate headquarters from Seattle to Chicago. Despite the safety concerns, the DC-10 went on to outsell its closest competitor, the Lockheed L-1011, by nearly 2 to 1. This was due to the L-1011s launch being delayed and the DC-10 having a greater choice of engines (the L-1011 was only available with Rolls-Royce engines, while the DC-10 could be ordered with General Electric or Pratt Whitney engines).
