Exocytosis in Paramecium

In Paramecium caudate, trichinosis are IOWA secretors vesicles that are released from the cytoplasm. We first observed how the presence of Alicia blue dye triggers normal secretion of trichinosis, and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracurricular and intracellular environment affects the secretion of trichinosis.Our first our hypothesis tested whether extracurricular calcium is required for the secretion of trichinosis by reading cells with EST., an agent that blocks calcium ions; our second tested whether increased calcium will counter the inhibitory effects of EST.; our third tested whether adding different ion, like Magic, can also counter the inhibitory effects of EST.; and our fourth hypothesis tested whether the release of intracellular calcium by adding caffeine or oenophile affects exoticism.Our results demonstrate that exoticism of tricycles is dependent on the presence of calcium ions in both the intracel lular and extracurricular environments. Introduction: Exoticism in eukaryotic cells is the process in which macromolecular material is released from the cell into the extracurricular environment; one example of exoticism is the secretion of trichinosis in paramecium. Trichinosis are secreted from the cell as a defense mechanism when certain stimuli are introduced into the extracurricular environment.The secretion of trichinosis is controlled by the presence of Ca*+ ions within the plasma membrane and in the extracurricular environment. The purpose of our experiment was to observe the extent to which exoticism is pendant on the presence of extracurricular and intracellular calcium ions, and to determine if other extracurricular ions can have the same effect as calcium. The cells were first treated with 0. 03% Alicia blue dye, which triggers normal exoticism. Cells were then treated with EST., an agent that inhibits calcium, in order to observe how triptychs secretion is affected when calcium ions are sequestered.Additional calcium ions were added to the extracurricular environment to determine if the effects f EST. could be countered by increasing calcium. The cells were then exposed to a different ion, Magic, to observe if a different ion could have the same promoting effect in the extracurricular environment as calcium. Finally, the effect of intracellular calcium was tested by treating cells with a calcium oenophile (A23187) and caffeine, which both stimulate the processing of calcium into the cytoplasm of a cell. Results: Table 1: Observations of triptychs secretion in Paramecium caudate.Data show owe a small sample of cells on a microscope slide responded to the addition of 0. 03% Alcott blue dye, 7. 5 run EST., 0. 14 run A23187 in 1% DMS, 50 run caffeine, and 25 mm magnesium chloride (Magic). The data were obtained by viewing cells under a microscope; the cells were counted prior to treatment and the number of cells secreting trichinosis was counted after treatment.

Hamlets Fatal Flaw Essay

Hamlet’s Fatal Flaw was that he had a hard time carrying out his plans. Many times did Hamlet plan on doing things, yet he did not carry out these plans. Hamlet was not a bad guy, but more of a tragic hero. In the opening scenes of the play, the Ghost of Hamlet’s father reveals the truth about his death to his son. He tells Hamlet to avenge his tragic murder. Hamlet’s response seems like he has quick plans to carry out his fathers wishing, by saying â€Å"Haste me to know’t that I with winds as swift†Ã‚ ¦ May sweep to my revenge.† (p. 29 lines 27-29) Unfortunately, Hamlet’s inability to act on his father’s extortion has him reluctant to kill the King Claudius by the end of that very scene, when he says, â€Å"This time is out of joint, O cursed spite, that I was ever born to set it right.† (p. 35 lines 197-198) Here, Hamlet is already having doubts and wishing that he wasn’t the one that had to carry out the revenge for his father. Obviously Hamlet has real problems when it comes down to dealing with things. As the play goes on, Hamlet still has not done a thing to avenge his father. In act II, scene 2, Hamlet decides that before he can avenge his father’s death, he must make sure that the Ghost was telling the truth. This simply gives Hamlet more excuse to procrastinate. Hamlet makes a plan to have a play in which he will test the kings reaction to. The play would be about a king who is murdered by someone putting poison into his ear. Then the murderer becomes king and is loved by the fallen kings wife. Just as it was for Claudius who killed the king and took his wife. When the play is seem by Claudius, Claudius becomes outraged and ends the play. Hamlet knows now that Cladius is guilty. Even here, hamlet is speaking to his friend Guilderstern and says â€Å"I lack advancement† (p. 81 line 338) when his friend asks what is wrong with him. I think that Hamlet knows his flaw but he won’t act on it. In act III, scene 3, Hamlet is ready to kill the king, but stops himself because the king is praying. Hamlet thinks that because the king is praying that if he killed him now the king would go to heaven. He decides yet again to delay avenging his father’s murder, this time until he can kill the King while he is in a vile condition, such as â€Å"When he is drunk asleep; or in his rage; Or in the incestuous pleasure of his bed.† (p. 87 lines 89-90) Later,  Hamlet even proclaims; â€Å"How all occasions do inform against me, and spur my dull revenge.† (p. 104 lines 33-34) In the end of the play, we see that Hamlet’s inability to act causes his tragic demise. Hamlets failure to revenge his father when he should have, costs him not only his life, but also his mother’s. In the final scene, Hamlet duels with Laertes, who has conspired with the King to kill Hamlet. In the King’s attempt to kill Hamlet, he accidentally poisons the Queen. Laertes delivers the fatal wound to Hamlet with a sword dipped in a deadly poison and it is only with his final life breath that Hamlet finally kills the King. So, Hamlet has finally killed the king, but not by going out and killing the king like he said, but with a poison the king made himself to kill Hamlet. But it would be okay to say that Hamlet avenged his father, and his fathers later wish for the queen to be left to die without Hamlet killing her. Both Hamlet’s and his father’s names are cleared too. Basically, everything is made clear to the people and besides Hamlet’s sad death, everyone who deserved to die or be killed, was killed. Hamlet obviously wouldn’t have made a good king anyways, without the ability to act on your own wishes, you would never rule a kingdom very well.

Blaxploitation Essay Research Paper The Emergence of

Blaxploitation Essay, Research Paper The Emergence of ColourIn today? s culturally diverse, politically right society, it is difficult to believe that at one clip racism was non merely accepted as the norm, but enjoyed for its amusement value. Persons of African descent in North America today take the big, diverse pool of chances offered by the movie industry for granted. Much like Canadian theatre nevertheless, there was a clip when a black adult male in any function, be it servant or break ones back, was virtually unheard of. It took the blaxpliotation movies of the early 19 1970ss to alter the stereotyped word picture of Black people in American Cinema, as it took The Farm Story, performed by a little troop of Canadian histrions, to make a Canadian theater industry. To be more specific, it took the release of Melvin Van Peebles, Sweet Sweetback? s Baadasssss Song, in 1971, to alter the tradition position of Black people in American movie. ? Porter? s Tom was the first in a long line of socially acceptable Good Negro characters. Always as Toms are chased, harassed, hounded, flogged, enslaved, and insulted, they keep the religion, n? er bend against their massas, and remain hearty, submissive, stoic, generous, selfless, and oh-so-very kind. ? ( Bogle,4 ) The early soundless period of film introduced five basic originals for Black characters: the Tom, the Coon, the Tragic Mulatto, the Mammy, and eventually, the Brutal Black Buck. America? s foremost Black character found manifestation as the aforesaid Uncle Tom in Edwin S. Porter? s, Uncle Tom? s Cabin, which was released in 1903. ? The paradox was that in actuality Tom wasn? t Black at all. Alternatively he was portrayed by a nameless, somewhat fleshy histrion made up in blackface. ? ( Boggle, 4 ) This was a common pattern developed by the theatre, and carried over, as were many of the moving techniques, to silent movie. Tom? s presence, and the visual aspect of the fou r Black originals which were to follow, served the same intent: ? to entertain by emphasizing negro inferiority. ? ( Boggle, 4 ) Although holding no positive consequence on the position of Black people in America socially, the tom character opened the door for Black histrions in film. Sam Lucas became the first black adult male to be cast in a prima function as a Tom, and in 1927, Universal Pictures signed James B. Lowe, a fine-looking black histrion, for the lead function in the Universal Pictures production of Uncle Tom? s Cabin. Lowe was chosen to play the portion because movie manager Harry Pollard, a former blackface histrion, believed he? tantrum in with the realistic demands of the times? ( Bogle, 6 ) Tom was to be followed by the coon, although he remained the cinematic Black character favourite. Where Tom was an adorable character, the coon provided audiences an object of amusement. Two discrepancies of the coon shortly emerged: the piccaninny and the uncle ramus. ( Bogle, 7 ) The Pickanny was the first coon type to look in film. ? By and large, he was a harmless, small crazy creative activity whose eyes popped, whose hair stood on terminal with the least exhilaration, and whose jokes were pleasant and diverting. ? ( Bogle, 7 ) The Pickaninny provided audiences with an amusive recreation, and shortly found his manner into the Black Marias of the mass audience. Following to debut was the pure coon, ? a good-for-nothing nigga? , whose undependable, brainsick, lazy nature was good for nil but feeding and doing problem. This character found its pinnacle of success in Rastus, a good-for-naught Black featured in a series of movies released between 1910 and 1911. The concluding coon brother would emerge as the tidal bore to delight metaphoric cousin to the Tom. Quaint, and na? ve, the Uncle Ramus character distinguished himself through his amusing philosophizing. ( Bogle,8 ) In general, the cinematic coon was used to bespeak the Black adult male? s contentment with his submissive place in society. Besides emerging around this clip period is the tragic mulatto: a negro visible radiation plenty to go through for white, who must contend against the negro contamination to either rise above his coloring material, or autumn victim to it. Mammy, a character closely related to the amusing coon, was the following to emerge. Headstrong and copiously female, Mammy debuted around 1914. The Mammy function would be perfected by Hattie McDaniel in the 1930? s. From the mammy functions emerged the Aunt Jemima, a male or female character who had a spot more tact and were, for the most portion, Sweet and congenial. The concluding original emerged in D.W. Griffith? s The Birth of a Nation ( 1915 ) . Picturing life before and after the civil war, all four originals are present in this movie. It depicts recreant Blacks who overpowe r the charitable, white Southerners and leave on a way of lechery, coarseness and offense. The ultimate end of these wild beast-men is sexual laterality of the pure, guiltless white adult females. At the movies decision, the white work forces of the? unseeable imperium? drive in to salvage the twenty-four hours and reconstruct white domination in the South. Proudly know aparting, D. W. Griffith, touted as one of the fore-fathers of film, uses his movie command to demo audiences what happens when? slaves get overweening? . The five originals would govern in black film for the following 50 old ages. Although Black movies did emerge, it was for the most portion produced by white production companies for a black audiences. Black Independent production companies such as the Ebony Motion Picture Company began to emerge in the 20? s, but the stereotypes and capable affair stayed the same. A common subject of societal mounting, the ultimate end of the Black being suburban life, ruling Black theaters. ( Cham, 20 ) Throughout the 30? s and 40? s the mobster movies rose to the bow, normally picturing gun-totting, slick-talking Blacks, entent on doing it large. Despite the presence of Black independent film makers such as George Randall, African American issues were basically ignored. The 50? s and 60? s brought societal agitation and the Civil Rights Movement brought a demand for movies with a stronger message. The originals of the 20? s and mid-thirtiess were no longer acceptable, and the few Hollywood? race movies? ( which normally starred Sidney Poitier ) , were no longer adequate. ? Hollywood was still unable to spot or picture the full spectrum of Black American life and culture. ? ( Cham, 21 ) In 1971, Black movie experienced an epiphany. It came in the signifier of a low-budget, severely made Gallic movie by the name of Sweet Sweetback? s Baadasssss Song. It was created about wholly by one Black man- Melvin Van Peebles. This marked a extremist alteration in Black film. ? In 1971, Melvin new wave Peebles dropped a bomb. Sweet Sweetback? s Baadasssss Song was non polite. It raged, it screamed, it provoked. It? s echos were felt throughout the state. In the Black community it was both hailed and denounced for it? s sexual rawness, its butch hero, and its word picture of the community as downpressed and in demand of rescue. ? ( Diawara, 118 ) Van Peebles movie sparked an detonation of what would go known as blaxploitation movies. What Sweet Sweetback Baadassss Song did was interpret Black Stereotypes otherwise. He, and other Black managers of the clip, took the Black Buck, Coon, and Mammy stereotypes of the epoch before and modernized them. ? Mammy? lost weight and grew an Afro, going the ultra-stylish prima donna which was personified best by actress Pam Grier. The Black Buck emerged dominant, ready to contend his historical oppressors. Blaxploitation movies acted as a cleaning procedure, through which black movies were finally able to accurately picture the African American experience. Directors such as Spike Lee and Jon Singleton were able to make? race movies? which confronted the serious urban issues of the clip, without utilizing old stereotypes. It is of import to observe, nevertheless, that Sweet Sweetback is non considered a blaxpoitation movie, as it is excessively artistic to be considered such. Rather, Melvin Van Peebles foremost movie was the accelerator for the cleaning blast. ? The Farm narrative? marked a point in time- before it there was no Canadian individuality in theater, after it there was. In the same manner, Melvin Van Peebles? film marked the minute when African Americans reclaimed their individuality. They were no longer content with the cinematic functions offered to them, and so they began to make their ain. Although blaxploitation movies were subsequently commercialized, their purpose and consequence stayed consistent, and have created the ethno-conscious film industry we find today. Bogle, Donald.

Figurative Language Versus Literal Language Essay

Figurative Language Versus Literal Language - Essay Example On the other hand, literal language is the complete opposite of figurative language because it means exactly what it says; what is spoken should always be taken as pure fact. Many people often get confused about figurative language and what it actually refers to. This is why it is so important to understand what the language is referring to and what the intended meaning is. In this paper, the ten most common forms of figurative language will be discussed. They are as follows: (1) idiom; (2) analogy; (3) metaphor; (4) simile; (5) cliche; (6) amphiboly; (7) flame word; (8) hyperbole; (9) euphemism; and (10) colloquialism. The first type of figurative language, idiom, is a phrase that is made up of unrelated words that only make sense when used together. Idioms evolve over time as people get comfortable saying them. An example of an idiom would be ‘a slip of the tongue.’ Of course, it is impossible for a tongue to actually slip, but the idiom is referring to a misspoken wor d or phrase. Idioms only make sense when the listener understands all the parts of the phrase individually and then is able to put them together to get the intended meaning. People who are in the process of learning a new language often don’t understand idioms because they simply don’t have the vocabulary to do so. ...The third type of figurative language, metaphor, is different from analogy because it makes a direct comparison between two unrelated things. The purpose of a metaphor is to show or express emotion where simple language would not suffice. An example of a metaphor would be ‘his house is a fortress.’ It is very unlikely that someone’s house would be a fortress, but what the metaphor is trying to explain is that the house is impressive. A metaphor is often used in poetry to describe something in a beautiful way. If someone took a metaphor literally, then they might have a hard time believing it. The next type of figurative language, simil e, is very similar to a metaphor except it uses the word as or like when making a comparison between two unrelated things. A simile is also often used in poetry. An example of a simile would be ‘the boy runs as fast as a cheetah.’ The phrase does not actually claim that the boy can run the same speed of a cheetah, only that he runs so fast that it seems like he does. There are very few misunderstandings over a simile because it does not make a direct comparison and so cannot be taken literally. The fifth type of figurative language, cliche, is a common phrase that has been used so much that it has lost its original meaning. Cliches are used in everyday speech and eventually become part of a language. An example of a cliche would be ‘time will tell.’ The time cannot actually tell anything since it has no form of communication except to give the time. Just like an idiom, a cliche would be hard for someone who is learning a new language to comprehend.  Ã‚  

Metropolis Police Department Term Paper Example | Topics and Well Written Essays - 750 words

Metropolis Police Department - Term Paper Example According to the discussion, the city mayor and the elite council members plan to fire the chief. The person is thinking about the responsibilities aligned in the job that will be offered. The stakeholders are intensely affected of the malpractices of the current police department. People would not trust the cops because of the latter’s unethical conducts. The possibility of replacement for the current chief is truly tangible owing to his mismanagement, but the risk is on the interim or next chief who will be implementing more changes in force and sustain credence of the minority groups. The court should investigate the atrocity of the current administration, and once the court has proven the malpractices of the police department, the department needs to be renewed. The greatest challenge for the court is to order an extensive revision of the police force staffing. It has been said that discriminations arise from the chief that criticized African-Americans, women, and Hispanic s; therefore, it is best implicated to hire forty percent of blacks and Hispanic surnamed-Americans and ten percent women in order to desist the race, nationality, and sex discrimination happening in the state. The attitudes of key staffing in the police force are the optimum significant ingredients in identifying the level of entity compliance with public regulation, and the extent to this freedom is exercised in the staffing process. Environmental elements include demography, behavior of the domestic community, and the domestic government support for assertive action. The state should uphold the greater notion of the necessity for equal employment opportunity for both men and women.

National culture and commitment Essay Example | Topics and Well Written Essays - 4000 words

National culture and commitment - Essay Example The cultural dimension of individualism versus collectivism will be discussed in detail and the implications for the organisation will be presented. Finally, the Saudi culture will be described, with particular attention being paid to the Islamic and Bedouin traditions underpinning Saudi culture, and their impact on organisational management. Over decades of scholarly explorations, the topic of national culture has remained a much favoured topic, with diverse views on national culture being proposed. The increase in cross cultural interactions, brought about by globalisation, has further contributed to the need for deeper understanding of the theoretical background and concepts of national culture and its influence on employee and organisational behaviour (Kalliny, Cruthirds, & Minor, 2006; Klein, Waxin, & Radnell, 2009). The characteristics of different cultures have been studied by different scholars, and various dimensions of national cultures have been used to measure and define various cultures (Hofstede, 1998; House et. al, 2004; Mallehi 2007; Pothukitchi et.al, 2002; Schein, 1998; Tayeb, 2005; Trompenaars & Hamden-Turner, 2000). The foundation for culture is the shared set of values and collective beliefs which in turn shape behaviour (Morgan, 1986). Research has indicated that such things as cognitive frameworks, learned behavioural norms, shared meanings and perceptions, ethical codes, stories, heroes, symbols, and rituals all serve to shape our sense of culture and thus our behaviours (Alvesson, 2002; Brown, 1995; Kreitner & Kinicki, 1998). Because of this shared foundation, people of the same national culture are likely to behave in a similar manner and to share similar attitudes and perceptions (Hofstede, 2001). According to Francesco and Gold (1998), culture is the â€Å"most useful tool in identifying and explaining differences in how people behave†. Culture is not static, but rather is constantly changing and evolving.

Learning and Development is a Luxury that Organisations Can Afford Essay

Learning and Development is a Luxury that Organisations Can Afford only in Financially Prosperous Times - Essay Example Employers and employees both gain benefit from learning and development. From the viewpoint of employer, learning and development are significant to preserve or develop the knowledge, the abilities and the performances so that they can fulfil the business objectives. From the viewpoint of employees, learning and development help to accomplish performance goals in a successful way. They also deliver an outline to recognise new abilities and knowledge and apply them in the practical work environment. As a result, learning and development can also motivate the employees (ACCA, 2010). One of the most significant assets for every organisation is its employee force. In the modern business environment, knowledge, originality, and passion are crucial differentiators for any organisation or industry. Besides, when it comes to achievement and winning competition, advanced talents and proficiencies in the areas of mechanical, managerial or operational domain become necessary for organisations. Though abilities and knowledge are replaceable in the long-run, the cost of switching employees and providing required training to develop them is huge and it can impact on organisational performance (Mitchell, 2008). Investment in learning and development on a regular basis is significant to retain or ensure lesser employee turnover and inspire them to be involved more in the work and achieve the goals for the organisation. Organisations always require skilled employees who can perform efficiently their allocated tasks. In this rapidly changing business environment, it is extremely necessary to provide effective performance continuously. But the key conflict or constraint with respect to learning and development is the budget. Organisations that are smaller have less money to invest on learning and development. Yet, in present day’s even small organisations have more learning and developmental requirements. Contemporary business environment is different and it comprises of m any innovative technologies which were considered to be science fiction (sci-fi) few years ago. The globalisation is impacting the businesses structures and organisational cultures. New regulations are impacting the working practices, and employees have greater prospects from their companies and working lives. In the workplace, it is necessary for employees to adjust and to react with the fluctuations rapidly and without loss of efficiency. In other words, employees need to understand quickly new tasks, adjust with the new procedures, take additional responsibilities, grasp new technologies and obey the new legal necessities viz. health and security guidelines and data security among others (Clifford & Thorpe, 2007). Learning should be constant with the aim to maintain pace with the business fluctuations. Learning and development cannot be conveyed except when there is growth requirement. Growth requirements arise when employees’ actual performances differ from the desired pe rformances. The central idea of learning is that every person possesses the ability to learn if they are provided with adequate time and support (Clifford & Thorpe, 2007). Learning and development activities can be influenced by several aspects. Certain significant issues that impact on the learning and development are inadequate resources, traditional culture, embedded approach towards training, stress of

Failure of the Mercantilism Essay Example | Topics and Well Written Essays - 500 words

Failure of the Mercantilism - Essay Example From this paper it is clear that  the mercantilists believed that the presence of more gold and silver bullions in a country translated to a better economy than any country with minimal gold and silver reserves. The theorists believed and encouraged countries not to use their gold deposits for trade even when the people desperately needed these products. The mercantilists had the idea that any successful trade meant the gain of one party and the loss of the other party. They never viewed the trade between two countries as being mutually beneficial. They encouraged their countries to influence the international trade and ensure that the citizens did not compromise their gold and silver deposits.This essay stresses that  the mercantilists developed ideas that were meant to promote the interests of the merchants since they were believed to be a significant source of a country’s gold and silver reserves. The government placed the role of attracting more gold and silver to the country to the merchants and also entrusted them with implementing relevant measures that would seek to regulate the economy. Malynes, for example, states that the merchants more specifically the bankers would develop appropriate measures that would see the increase in the supply of specie into the country. Malynes rejected any effects of the exchange rate in influencing external trade and trusted the â€Å"tricks of the bankers† to solve the economic problem experienced in the country.

Staffing Organizations Part 1 Essay Example | Topics and Well Written Essays - 1250 words

Staffing Organizations Part 1 - Essay Example Thus, terms of employment will entail permanent employment contracts, in which the employees will have secure provisions for their job positions. The permanent employment-terms fosters employee loyalty and keeps the workers settled as they focus on work; hence, it will allow full concentration of workers at work; hence, effective service delivery (Aswathappa, 2005). Additionally, the business will also institute measures of eliminating conflicts among employees and misunderstandings that may arise at the workplace. However, there will be strict corrective action, including facilitation for verbal warnings, as well as, written documentation as warning for misconduct, to facilitate corrective action that follows legal confines of permanent employment guidelines. There will also be employee performance evaluation and awarding of incentives and feedback to motivate the employees accordingly. The support structure for employees will help develop employee relations with the business, creat ing loyalty and motivation to work effectively. Treating employees less favorably or discriminately based on age, religion, race, sex and disability among others are forms of discrimination under various provisions of law. Therefore, in creating a successful working environment in the business to avoid claims of disparate treatment, the first procedure is to review the state laws concerning termination processes as applicable to the permanent employment terms. This will help in ensuring the business follows due process in terminating the employees who fail to meet the working requirements and expectations without claims of disparate treatment arising. The management will file the issued documentation of warning before termination. Additionally, in factor of employment benefits claims, the business will follow due procedures as stipulated in the state laws and bylaws in the location of the business. Thus,

Global Strategy and Local Needs in the Luxury Car Market Essay Example for Free

Global Strategy and Local Needs in the Luxury Car Market Essay 1 Introduction Since the 1980’s researchers have been trying to understand what globalization is and how competitive advantage can be gained out of it. This study will look at this movement with a critical eye and reflect whether or not it is sometimes better to give local needs priority in management decisions. The purpose of this study is to analyse whether the â€Å"Global strategy, but local needs† assumption leads to success. The objective is to provide scientific evidence for this strategy, analyse different organizations’ strategies and provide a possible recommendation for the best practice. Globalization is a driver of luxury 1 but it is not the best solution to apply this approach in all strategic decisions. This paper will not only look at this strategic approach in general, but will try to focus in specific on the luxury car market. The luxury segment is a fascinating subject for scientific research, because it still provides possibilities for relatively fundamental research within its niche. 2 Although there is considerable literature about specific brands, there is a lack of systematic and scholarly work that analyses the luxury car phenomenon itself. 3 The importance of this segment has also been emphasized in Sergio Marchionne’s recent speech to the shareholders (appendix 7. 2). The CEO of the Fiat S. p. a and of the Chrysler Group LLC underlined that his strategy for the future of the Group is located in the premium4 car production. 5 The motivation of this paper therefore is to analyse the challenge Maserati will have to address and to arrive to some practicable conclusions. 1 Cf. Kapferer/Bastien 2012, p. 12. 2 Cf. Heine 2012, p. 6. 3 Cf. Berger 2001, p. 160. 4. Expression intentionally quoted to illustrate a later explained statement 5 Cf. Fiat S. p. a. 2012b. Definition and terminology 1. 1 2 Methodology The findings of this project are derived from primary, secondary and tertiary sources of information. The tertiary source was mainly the catalogue of the Deutsche Nationalbibliothek in Frankfurt. Another important part of the data collection contributed the Internet. Most data has been found with the search engine google. com and scholar. google. com and the homepages of the relative brands mentioned in the project. The biggest part of the project’s information was taken out of secondary sources such as textbooks, newspapers and specific literature. Finally, the annual reports of 2011 of selected brands have been consulted. 2 Definition and terminology 2. 1 Strategy â€Å"†¦ Strategy in corporate practice is an integrated concept with the objective of ensuring long-term survival in active interaction with the competition †¦Ã¢â‚¬ 6 In today’s everyday changing business environment all companies are forced to reassess their strategies, their structures and their processes regularly. But the answers to every strategic and organizational challenge is varying among industries. 7 Therefore first a summary of different general strategic alternatives will be presented. Afterwards a detailed analysis of the characteristic strategy in the luxury car market will be developed. 2. 2 Global or Local Strategy In this chapter both terms global and local strategy should be defined. Moreover the strategic challenge of a business to decide between both strategies should be analysed. 6 Cf. Kotler/Berger/Bickhoff 2010, p. 12. 7 Cf. Bartlett/ Ghoshal 1990, p. 17. Definition and terminology 3 Businesses have been international since ancient times and at its beginnings international business had simply the form of exporting and importing. Any business that carries out some of its activities across national boundaries can be defined as an international business. 8 In the 70s and 80s keywords as standardization, rationalization and centralization marked the new tendency towards globalization. 9 Globalization is a term that emerged in the 1980s/90s10 and that has become a buzzword in the 1990s. 11 Originally globalization was only an economic phenomenon that described the integration and merger of national economies, and the development of communication and production of knowledge, transportation and migration. 12 Today the extent to which the organization’s activities are spread across geographical regions has become a major consideration in the implementation of an organizations strategy. 13 A global strategy is the tendency of a company to a consistent strategy and adaptation to local circumstances become redundant. Global organizations gain competitive advantage overcoming national and continental boundaries. Therefore it was a widely held belief that there was the risk that the globalization would overrun all regional and national differences. 14 Though today we have evidence that there is no â€Å"global village† and that regional and national differences cannot be so easily neglected. On the contrary the majority of the apparently global organizations use local differences to gain competitive advantage. 15 Therefore numerous literature and research on the counter-rotating trend to globalization, the so-called localization, can be found. Localization in general means the adaptation to or consideration of local market conditions. Most of the research concluded that the two apparently contrary concepts do not mutually exclude but depend on one another: â€Å"Globalization can mean the reinforcement of 8 Cf. Campbell/Stonehouse/Houston 2002, p. 255. 9 Cf. Bartlett/Ghoshal 1990, p. 36. 10 Cf. Lohmeier 2008, p. 9. 11 Cf. Rohm 2010, p. 4. 12 Cf. Lohmeier 2008, p. 9. 13 Cf. Campbell/Stonehouse/Houston 2002, p. 254. 14 Cf. Lohmeier 2008, p. 10 15 Cf. Lohmeier 2008, p. 58. 4 Definition and terminology or go together with localism as in ‘Think globally, act locally’†¦Ã¢â‚¬  16 . Numerous literatures even deduce a new concept called â€Å"Glocalization. † Glocal strategies are strategies that provide evidence to global and local players, to respond advantageous and purposeful to globalization. They should assist global players to localize their activities where worthwhile and show ways and means to local players to make use of the global area respectively in both cases without abandoning their global or local character. 17 2. 3 Bartlett’s and Ghoshal’s model According to Bartlett and Ghoshal there are three traditional strategic directions a company can follow. Tab. 1: The three strategic directions 18 Multinational Global International Strong local presence Cost reduction through Usage of knowledge and through respect of national centralized but worldwide competences of the HQ needs oriented activities through worldwide diffusion and adaptation 2. 4 The multinational organization The multinational organization according to Bartlett and Ghoshal is the archetype of the organization. At the beginning of the 1900th century this was the most diffused organizational model. As shown in figure 1 in the multinational organizational model the HQ is at the centre with many decentralized, interdependent and autonomous branches surrounding it. The specific needs of the local markets are encouraged and therefore they are able to react to local needs. Historically this organizational model was the one of many European companies that expanded into foreign countries. Several of these companies originally where family owned companies. Processes were based on personal relationship and 16 Cf. Pieterse 1995, p. 49 zitiert nach Lohmeier 2008,p. 53. 17 Cf. Lohmeier 2008, p. 64. 18 Cf. Bartlett/ Ghoshal 1990, p. 32. 5 Definition and terminology informal contacts rather than formal structures and systems. Therefore only elementary financial control was necessary. 19 Branch Decentralized federation: Many key assets, responsibilities and decisions are decentralized Branch Branch HQ Branch Personal control: Informal HQ – subsidiary relationship, simple financial control Branch Multinational mentality: Management considers overseas operations as portfolio of interdependant business. Branch Figure 1: Multinational organization 20 2. 4. 1 The international organization This organizational model has similarities to the multinational organization. However as shown in figure 2 the branches are more dependent on the transfer of information and knowledge from the HQ. The objective of this kind of organization is to transfer knowledge and competences in aspects such as technology or marketing to underdeveloped foreign branches. The national branches can adapt products or strategies, while the HQ determines innovation and processes. In comparison to the multinational organization model there is more systematization and control. According to Bartlett and Ghoshal the international organization model had its breakthrough in the post-war period. The international organizational model is the model for the typical American Management culture of empowerment and delegation. 19 Cf. Bartlett/Ghosal 1990, p. 73. 20 Cf. Bartlett/Ghosal 1990, p. 74. 6 Definition and terminology Branch Branch Coordinated federation: Many assets, resources, responsibilities and decisions are decentralized but controlled by HQ Branch Branch HQ International mentality: Management considers overseas operations as appendix to a central domestic corporation Branch Administrative control: formal management planningand control systems allow higher HQ-subsidiary linkage. Branch Figure 2: International organization 21 2. 4. 2 The global organization Global companies develop their products and strategies considering only one equal worldwide market. Product development, production and marketing strategies remain centralized. 22 As shown in figure 3 the most important characteristics of the classical global organization have HQs that are a centralized hub that severely controls the branches and a management-mentality that views the world as one economic entity. The main feature is the centralization of assets, resources and competences. The function of branches is reduced to sales and services. In some cases financial competitive advantage is gained outsourcing the production sites abroad. Compared to the multinational and international organizations the branches in global organizations have less power to develop or modify new products and strategies. Managers in global organization, especially those located in HQ, often are more concentrated on the global market and consider the market to be equal worldwide. They have no comprehension of the local needs because there is no exchange of information between HQ and the national branches. 23 21 Cf. Bartlett/Ghoshal 1990, p 77. 22 Cf. Bartlett/Ghosal 1990, p. 31. 23 Cf. Bartlett/Ghoshal 1990, p. 75 f. 7 Definition and terminology Internationalization pioneers like Henry Ford build up their production plant according to this model and the Japanese started their offensive in the 70s and 80s with this model. 24 Normally global organizations first where very successful in their home market and used this success then to expand internationally. 25 Branch Branch Centralized hub: Most of the strategic assets, resources, responsibilities and decisions centralized Branch HQ. Branch Operational control: Tight control of decisions, resources and information through HQ Branch Global mentality: Management considers overseas operations as channels for the supply to a unified global market Branch Figure 3: Global organization 26 2. 4. 3 The transnational strategy Bartlett and Ghoshal claim that the traditional directions do note lead to adequate results anymore. Global and international organizations look out for a centralized answer to a worldwide market opportunity. Multinational companies search local solutions. Therefore Bartlett and Ghoshal developed the assumption for a new approach to solve the challenge of increased competitive and changing environment: The transnational strategy. 27 Companies nowadays can only survive in the competitive environment if they succeed in developing simultaneously worldwide competitiveness, multinational 24 Cf. Bartlett/Ghoshal 1990, p. 75. 25 Cf. Bartlett/Ghoshal 1990, p. 31. 26 Cf. Bartlett/Ghoshal 1990, p. 77. 27 Cf. Bartlett/Ghoshal 1990, p. 33 and p. 90. Definition and terminology 8 flexibility and global learning capabilities. These are the main elements of the transnational model. 28. The transnational model is a symbiosis or rather compromise of the other three traditional strategic directions. It combines both kind of competitive advantages: Because the affiliations are seen as strategic partners they can better respond to local needs and global synergies can be positive side effects. In the transnational model local markets are respected, and the proximity to the market is mainly an instrument to react more flexibly on a global scale. 29 The distinction between multinational and transnational companies is the amount to which the HQs are directly involved in the management of the branches. While a transnational company often has a strategic centre that manages to a high degree all the global operations a multinational company does not coordinate directly its foreign activities but rather considers the branches as interdependent business. The transnational organization acknowledges that there are certain resources and competences such as finance or research and development that are better centralized in the HQ while other resources are more advantageous to be decentralized in the markets to spread the competences on a global level. 30 2. 5 The Luxury Concept and Definition. The concept of luxury is known since ancient times. Lucullus, a roman senator who was famous in the ancient Rome for his marvellous evening events and his love for beauty, delicacies and sensorial pleasures, can be considered inventor of the luxury concept. 31 Chevalier and Mazzalovo provide a definition as follows: A luxury brand is selective and exclusive and provides an additional creative and emotional value for the consumer. It is a brand that is giving the desirable attribute of being scarce, sophisticated and in good taste. It also has a slightly understated and aristocratic attribute. 32 28 Cf. Bartlett/Ghoshal 1990, p. 33. 29 Cf. Bartlett/Ghoshal 1990, p. 84 30 Cf. Bartlett/Ghoshal 1990, p. 84. 31 Cf. Heine 2012, p. 2. 32 Cf. Chevalier/Mazzalovo 2008, p. viii Definition and terminology 9 According to Kapferer and Bastien a luxury brand can be defined by six criteria:33 †¢ An extremely hedonistic experience or product †¢ The price is exceedingly higher compared to the functional value †¢ Tied to a tradition, exclusive expertise and culture ascribed to the brand †¢ Accessible only through controlled and restrained distribution †¢ Obtainable with tailored supplementary services. †¢ Indicating a social representation, making the holder or beneficiary feel special and privileged 2. 6 Luxury versus premium car market The concept of luxury is represented in numerous sectors of activities 34. In this study we will look into more details of the specifics of the automobiles luxury sector. According to Chevalier and Mazzalovo luxury automobiles are â€Å"those cars that consumer perceive as being very special and different from the others. †35 It is necessary to differentiate between the concept of luxury and the concept of premium. The term luxury vehicle suggests a vehicle with a higher quality equipment, better performance, particularly precise construction, comfort, higher design, technologically innovative, and features that transfer an image, brand, status or prestige. Often the image is strongly related to the country of origin of the product. Premium products are upper-range branded products with an increased price without the emotional characteristics like hedonism or myth. „Upper premium brands remain comparative, whereas luxury is superlative. â€Å"36 Suitable examples for this difference can be found in the car industry. While an Audi A6 or A8 are super-premium cars because of the excellent usage value they provide, an Aston Martin or a Lamborghini are luxury cars because of their rarity and the prestige of the name. 37 33 Cf. Kapferer/Bastien 2012, p. 47. 34 Sectors of activities of luxury: Ready-to-wear cloth, jewelry and watches, perfumes and cosmetics, fashion accessories, wines and spirits, automobiles, hotels, tourism and private banking. 35 Cf. Chevalier/Mazzalovo 2008, p. x. 36 Cf. Kapferer/Bastien 2012, p. 43f. ; Cf. Kapferer/Bastien 2012, p. 53. 37 Cf. Kapferer/Bastien 2012, p. 53. 10 Strategic examples One historic management error that underlines the difference between luxury and premium is the Jaguar case. When Ford acquired Jaguar in 1989 they invested a lot in technology and training of the Jaguar employees. Thanks to common platforms with Ford they tried to sell small Jaguars. But this strategy seriously damaged the image of Jaguar and loosing the feeling of exclusivity they lost the luxury status. 38 3 Strategic examples In this chapter the before described theoretic information should be put together into a strategic framework. The strategic examples that will be considered are the most successful competitors of Maserati in terms unit sales: Porsche, Audi, Mercedes and BMW (figure 4). The first step was to obtain an overview of the structure of these companies and to identify their dependencies among each other and with other organizations (appendix 7. 3). The second step was to identify certain characteristics of these organizations and to put them into a framework developed to identify their degree of globalization or localization (appendix 7. 4). Based on this information a picture of their strategic directions has been deduced (appendix 7. 5). Bentley 2,57% Audi 6,56% Maserati 1,81% Jaguar 3,06% Maserati Market 2012 Aston Martin 1,74% Ferrari 1,26% Lexus 0,09% Porsche 48,43% BMW 12,23% Mercedes-Benz 22,25% Figure 4 The Maserati market in Germany in 2012 (market shares) 38 Cf. Kapferer/Bastien 2012, p. 51. 39 Management Services Helwig Smitt GmbH, Hofgeismar. 39 Strategic examples 3. 1 11 Daimler AG Gottlieb Daimler and Carl Benz invented the automobile in 1886. 40 Today the Daimler Group integrates different car manufacturers such as Mercedes-Benz, Smart and Maybach. Cooperating with various organizations worldwide it has converted from a mainly domestically oriented exporting company to a globally operating one. The company is now well established not only in Europe but also in Brazil and Argentina and has established joint ventures also in China. 41 However for the Daimler Group â€Å"the cultural inertia has been difficult to overcome, and global pretensions and traditional German attachments form a contradictory and unstable mix. †42 Therefore it is difficult to classify the group to Bartlett and Ghoshals model. The Daimler AG is rather a combination between the multinational and the global organization. Mercedes-Benz being historically strongly connected to its German roots has a centralized HQ, but at the same time its business units have been made self-responsible profit centres and procurement of materials is globally coordinated for each group of materials. Furthermore this has been intensified through local settlement of direct production, more consultancies and engineering in the branches, and also some development tasks located outside Germany. 43. Daimler is relocating its production sites into emerging markets, as for example the recently opened site in Hungary. This trend can be underlined by its decreasing production figures in Europe. They are currently reducing their production in Sindelfingen. 44 3. 2 BMW AG The BMW group may be the most German focused of the three companies. It is globalized in its objectives rather than in its activities. 45 Approximately 60% of the production of BMW is still located in Germany (figure 5). However BMW is one of 40 Cf. Daimler AG 2012, p. 4. 41 Cf. Lane 2001, p. 84. 42 Cf. Lane 2001, p. 85 43 Cf. Lane 2011, p. 84f. 44 Cf. Berens 2012, p. 17 45 Cf. Lane 2011, p. 86. 12 Strategic examples the most respected brands in the world. The explanations for BMW’s success are a strong brand character, a stable, family shareholding and a very German business philosophy. 46 It can be deduced that having local roots increases the perceived value of BMW. Producing nearly all its automobiles in Germany customers perceive BMW as an authentic product of German culture. BMW follows the same strategy of keeping the Mini production in England. 47 South Africa, 3,06% China, 5,65% Austria, 5,91% CKD, 2,16% UK, 11,23% US, 15,88% Germany, 56,11% Figure 5: Vehicle production of the BMW Group in the world in 2011 48 Therefore BMW can be classified an international organization according to Bartlett and Ghoshal’s model. BMW’s key competences are centralized but many other competences are decentralized. Thus BMW efficaciously implements the strategy of local assembling and local purchasing in countries with high customs duties on imports such as Russia, Thailand or India. However, under the terms of the distinction between luxury and premium products, the cars assembled in Thailand would not longer be defined as luxury products. They do serve to initiate customers into the brand, who then should develop the desire to purchase a ‘real’ BMW ‘made in Germany’. 49 BMW’s Management Meeting Place is a good example for the acquisition of knowledge in the HQ and then transferring it to the branches. First this discussion platform has been started in Germany and then it was transferred to locations abroad. The fact that this strategy works, and that behind BMW probably stands a 46 Cf. Kapferer/Bastien 2012, p. 67. 47 Cf. Kapferer/Bastien 2012, p. 78. 48 Cf. BMW AG 2012, p. 28. 49 Cf. Kapferer/Bastien 2012, p. 78. 13 Strategic examples strong team is underlined by the fact that BMW has been rewarded being â€Å"The World’s Most Attractive Employer† by a study conduced lately. In fact the employee attrition ratio at BMW has decreased continuously in the last 3 years (figure 6). 5,85 percentage of workforce 6,00 4,59 5,00 4,00 2,74 2,66 2,16 3,00 2,00 1,00 0,00 2007 2008 2009 2010 2011. Figure 6: Employee attrition ratio at BMW AG 3. 3 50 Volkswagen AG The Volkswagen Group maybe is the most advanced example of a conglomerate of successful car manufacturers. Among all the subsidiary brands the most significant ones are Volkswagen AG, Audi AG and Porsche AG, but there are also Bentley, Lamborghini, Seat and Skoda (appendix 7. 3). In fact Porsche owns 32,5% of the Volkswagen Group shares. Succeeding in managing a portfolio of so dissimilar organizations under one umbrella certainly makes the Volkswagen Group to a transnational organization according to Bartlett and Ghoshal. The cooperation in-between the brands of the Volkswagen Group are very well developed. One successful example of this approach is the common hybrid drive used in the Porsche Panamera, Cayenne and VW Touareg 51 . In addition the Volkswagen group has only little external cooperation mainly in the area of researching. The key competences remain inside the group. Becoming an integrated automotive industry is part of the group’s â€Å"Strategy 2018†. However, every single brand has its specific targets. Volkswagen’s target is to 50 Cf. BMW AG 2012, p. 39. 51 Cf. Porsche AG 2012, p. 67. The Maserati case 14 become the global market leader by 201852. This underlines the global factor. On the other side Porsche’s target is to become â€Å"the leader of exclusive sports cars manufacturers†53. Audi finally has the target to become the â€Å"premium brand that delights customers worldwide† 54 . Therefore the group’s values and capabilities remain inside the group and with a broad portfolio of interdependent and specialized brands completely different target groups can be addressed. The Volkswagen Group leads the global tendencies of the considered companies. But the core strategic functions (e. g. RD and design) remain mainly German. However the Volkswagen Group also recognizes the importance of knowing the local sources and therefore has implemented the C3-Sourcing program. Becoming technical, organizational and social laboratories foreign branches contribute to the integration of the whole group’s worldwide activities. Hence some Audi models that have the same platform as Volkswagen models are now produced in Volkswagen factories in China. This local adaptation is the key of success for Audi’s sales in China, where the top members of the communist party cannot own a car unless it is made in China, but at the same time it forces the brand to give up their luxury strategy and replace it with a premium one. 4 The Maserati case 4. 1 Introduction to Maserati The Italian sports cars producer with the trident on the logo has been founded as Societa Anonima Officine Alfieri Maserati on December 1st 1914 in Bologna. Maserati was originally founded as a family business, but in 1937 it was sold to the Orsi family. In 1968 it was sold to Citroen and finally became part of the Fiat Group in 1993. 55 Thanks to his big sister Ferrari, Maserati has been reconstructed and from 2006 stands alone now in the structure of the Fiat S. p. a. (see figure 7). Today Maserati’s headquarter is based in Modena and it has two production sites in the north of Italy. Furthermore Maserati is divided in regions (Europe, Asia Pacific, 52 Cf. Volkswagen AG 2012, p. 233. 53 Cf. Porsche AG 2012, p. 14. 54 Cf. Audi AG 2012, p . 131. 55 Cf. Wikipedia 2012a. 15 The Maserati case. America and Middle East) with national branches in each separate country (e. g. France, Germany, United Kingdom). Maserati is currently becoming more and more significant for the rest of the Fiat Group. The first strategic milestone of the so-called â€Å"2010-2014 plan† was the integration of the Chrysler Group in June 2011. Figure 8 shows the increase of 30% of the workforce through this merger, mainly in North America. * including 58,5% Chrysler Group LLC Maserati (100%) Fiat Group Automobiles* (100%) AUTOMOBILES Fiat S. p. a.

Fiat S. p. a. 2012c, p. 30. 57 The Maserati case 16 The second milestone was the plan presented in February 2011 in which â‚ ¬ 500 million were invested for the relaunch a production site58. In this new pIant two new models will be produced: The new Maserati Quattroporte by the end of 2012 and the Maserati Ghibli in the second half of the year 2013. 59 Thereby Maserati plans to increase its sales: While in 2011 Maserati sold 6,159 vehicles worldwide, in 2013 20,000 units are planed and by 2015 a growth up until to 50,000 vehicles per year is projected. 60 The Maserati S. p. a. can be classified as a global organization. They concentrate their decision and strategy making in the HQ in Italy and product development, production and marketing strategies remain centralized. The function of the branches is reduced to the implementation and realization of sales, services and marketing activities. The reason is linked to the strong connection with the domestic country and the patriarchal organizational culture that has developed over the years. One cultural example for this approach is that usually in the branches employees refer to the HQ as â€Å"the factory†. And while until today Maserati’s production sites are located just in the domestic market, by the use of a common platform and production site with the Jeep Grand Cherokee in the United States for the new SUV model, Maserati will enter also in the global environment. 4. 2 Maserati’s strength 4. 2. 1 The cooperation with the Fiat Group Being part of the Fiat Group is strength and weakness at the same time for Maserati. Through the cooperation with the other brands of the group, Maserati can benefit from economies of scale and scope. E. g. particular engines for Maserati are developed and produced in the production site of Ferrari. Another example is the collaboration with Jeep that will allow the new Maserati Levante to share the expertise of Jeep in building SUVs. 61 Moreover the fact that the production of this new Model will be relocated to the United States will finally transform Maserati from a purely domestic manufacturer to a global player. 58 Officine Automobilitische Grugliasco. 59 Cf. Fiat S. p. a. 2012c, p. 34. 60 Cf. Wehner 2012. 61 Cf. Baedecker 2012. The Maserati case 17 4. 2. 2 The luxury image Maserati as a brand itself and the Maserati products are stereotypes of luxury. Maserati is like none of its competitors a unique iconic and superlative brand that stands for an extravagant Italian lifestyle and sportiness. It profits from its long-time racing experience and expertise in building extremely performing engines. Additionally some parts are tailor made and its products are positioned in an upmarket pricing class that does not correlate with the functional value they provide. Moreover until today the units sold are rather restricted and therefore it is still a rarity to see a Maserati on the road. Thus possessing a Maserati is to a high degree socially representative and makes the owner feel special and privileged. Maserati is a myth and continuous to benefit from this legend. 4. 2. 3 Driving performance Another very strong characteristic of Maserati is its driving performance. Driving a Maserati is an overwhelming driving experience from the very first moment you switch on the engine. The expertise in building extremely performing engines is definitely a strength that should not be underestimated. „Hearing a Maseratis V-8 engine scream on the way to its 7200-rpm redline is an experience gear heads will cherish. â€Å"62 4. 2. 4 The people that work for Maserati The people that work for Maserati are fundamental assets. A mixture of experienced and long-established employees on the one side and on the other side young, motivated and talented staff are the most important ingredient for the team that is able to face the current challenges. Maserati’s employees identify with the brand to a high level and therefore live for the brand. E. g. in the HQs in Modena are hanging poster with the slogan â€Å"I am Maserati†. 62 Cf. Floraday 2011. The Maserati case 4. 3 18 Maserati’s weaknesses 4. 3. 1 The image of the Fiat Group As mentioned above, being connected to mass-market brands like Fiat and Chrylser could affect Maserati’s luxury status. This is primarily related to the image of Fiat’s quality standards. The fact that some components are commonly introduced in both, Maserati and Fiat, could severely damage Maserati’s reputation. 4. 3. 2 Progress and technology Except for its engines, Maserati is not using the most advanced technology in his cars until now. Competition from other car manufacturers is very strong in this context (e. g. Porsche or BMW). Therefore this is a threat especially in those markets where technology and innovation are very important factors in the consumer buying behaviour process (e. g. Russia or Germany). Moreover while other manufacturers have already developed new propulsive forces e. g. the new Daimler electric fleet63, Maserati continued only the evolution of traditional fuel and diesel engines. As the petrol price rises also this threat is increasing. And depending on the trend of the environmental regulations in Europe and in the rest of the world, this lack of development could become an increasing challenge for the next future of Maserati. 4. 3. 3 Dealer network Another threat is the necessity to improve and expand the dealer network. There is a clear need to increase the distribution capillarity by appointing additional dealers. Moreover, there is also a need to transform the existing dealers bringing them to focus their activities and organizations on the brand. Dedicated sales, after-sales and marketing forces will be key to this transformation. E. g. most of the Maserati dealers sell also Ferraris and should adapt their staff with personnel dedicated exclusively towards Maserati. 63 Cf. Daimler AG 2012, p. 41. The Maserati case 4. 4 19 Maserati’s opportunities 4. 4. 1 Industrial opportunities With its current models range (Quattroporte, Gran Cabrio and Gran Turismo) Maserati is represented in the core segments.

Australian National Identity Essay Example for Free

Australian National Identity Essay According to Zimmermann there are as many legal systems as there are national states. Every country has its own unique legal system. However, we can allocate among them three main legal systems. These are: Civil Law, Common Law and Islamic Law. Civil and Common Laws are the most influential legal systems in the world, especially in its Western part. All three of these legal systems have existed and developed for many centuries. Further will follow the description of the historically appearance of each legal system separately. Civil legal system is considered to be the oldest and the most widespread one. It also known as Continental, Roman or Romano-Germanic law. In general, Roman law consists of a combination of three main subtraditions such as Roman Civil Law, Canon Law and Commercial Law. The development of Roman Law cover more than a thousand year period, starting from the publication of the law of the XII Tables in Rome (450 B. C. ) and the code of Emperor Justinian I Corpus Juris Civilic , which was created in period from 529 – 534 A. D and later developed by medieval legal scholars. Countries with Civil legal system: France, Germany, Japan, Russia and Uzbekistan. The Common law evolved in England since 11th century after being conquered by the Normans in 1066 A. D.. Afterwards William I the Conqueror created central government and began to standardize the law by combining the best of Anglo-Saxon law with Norman Law which led to a creation of English Common Law. â€Å"William’s enduring legacy was the creation of highly centralized legal system†. [1] (Kritzer, H, M, 2002). The case law originally appeared when the King understood, that many cases, which he had to solve were similar and needed standardization. During the 14th century legal decisions on the common law started providing precedents for the judges to follow. In 1769 Sir William Blackstone wrote Commentaries on the Laws of England, which became the basics of the most common law statutes. These are countries with common legal system: England, United States of America, Australia, Canada, Pakistan, and India. The Islamic Law is called Sharia. The primary sources of Islamic Law are Qur’an and Sunnah. Sharia covers all aspects of every day life of Muslims, including such things as: economics, family and social issues. The legal systems in the World are divided into three main groups: Common, Civil and Islamic legal system, as it was discussed earlier. According to Zweigert, K. and Kotz, H. there are five main differences this two legal systems can be compared: historical background, legal investigation, legal institutions, the sources of law and last one is its ideology. Civil and Common legal systems have both similarities and differences. The main difference between these two legal systems is that common law in England was based on customs, the court existed a long time before there were any written laws. In contrast, the Civil Law developed from ancient Roman Law of Justinian I The second difference is the role of sources of law. At present time there are such sources of law as codes, legislation, customs, judicial decisions (case law), equity and doctrinal writing. Each legal system has several sources from those which were mentioned above. For instance, as De Cruz (2007) points out â€Å"the main sources of law in Civil law countries are the codes, enacted law, doctrinal writing, custom and decided cases. †[2] Civil legal system is codified statutory system, where the main principles and rules are stated in codes. This means that codes and statutes are valued higher and case law is considered just as a secondary source of law. On the other hand the Common law system is uncodified, â€Å"governed by case law and statutes play only an auxiliary role to precedents established by courts†[3](Kritzer, H M, 2002). Equity and case law are accepted sources of law in Common law countries. They do not exist in Civil law jurisdiction. Equity is understood not only as justice but is also considered as a set of legal principles, which are applied in Common legal system. Equity deals with â€Å"situations by applying notions of good sense and fairness†. [4] (Elliott, C Quinn, F, 1996). The law is dominantly created by judge and often without checking the legislation, only by drawing analogy the previous similar cases. This moment shows the difference of the legislators in civil law and in common law. In the civil law, judges should apply the law, which was created by the legislator, on the basis of separation of powers. On the other hand, in common law the judge is given the power to create the law. Another difference between civil and common law system is the force of precedents. In civil law system, the court decides the particular cases according to the legislation and legal norms. But in the common law the courts are supposed not only to solve the cases, but also give an example of how similar cases have to be solved in the future. This means, that decisions, which are made by higher level courts in a specific areas are binding the lower ones to follow them. This makes the court in the common law the basis of legislation. Court procedures are also differentiating in both civil and common legal systems. We all know that at the court two parties cooperate by presenting their evidence to each other. Civil legal system has an inquisitorial procedure. In inquisitorial procedure the judge is the active person, who also takes more investigative role. Common law countries use the accusatorial system, which is also known as the adversary procedure. † The common law principle which places the responsibility for collecting and presenting evidence on the party who seeks to introduce that evidence. †[5] (Woodley, M, 2005). In accusatorial procedure judge is a passive person in comparison with the inquisitorial procedure. Moreover, the last word in court procedure (Civil legal system) has the defendant, whereas in Common law the last world has the prosecutor. Next difference would be legal institutions. It can be seen on the following examples. Trust is a branch of law which exist in Common law countries, significantly developed in England. It regulates relationship between trust and trustee. Trust is the person who delegates their ownership, whereas trustee is the person who owns trusts’ proprieties due to many reasons (e.g. underage) The principle of presumption of innocence works differently in Common and Civil law in criminal cases. In Common law it means that a person is innocent until his gilt is proven by the prosecutor and by the facts he presents. On the other hand in civil legal system, it suggests that a person is found to be guilty until he proved that he is innocent. Convergence theory is a system, when one particular country has a mixed legal system. Mixed jurisdiction in recent time, became a subject of huge debates and discussions in European Union. This is happening because, EU has united many countries with different legal systems under a single legislation. So now EU is becoming an area of convergence, where two major legal systems, civil legal system of the continental Europe and common legal system of England, are getting mixed with each other. But this kind of situation with the mixed jurisdictions did not occur only in European Union. Louisiana and Quebec are examples of mixed jurisdiction systems. Before being a part of USA, Louisiana was a French colony since 1731 till its cession to Spain in 1763. In this period of time Louisiana had a French legal system. But after its cession, French law was replaced by Spanish Law. The Spanish law included â€Å"Nueva Recopilacion de Castilla (1567) and the Recopilacion de Leyes de los Reinos de las Indias (a rearrangement of major legal texts up to 1680), and, in default of a specific rule in a later enactment, the Siete Partidas (a compilation of laws, based on the Justinian compilation and the doctrine of the Glossators, made under King Alfonso X in 1265 and formally enacted under King Alfonso XI in 1348)† (Tetley,W., 2000). On 20 December of 1803 Louisiana became part of United States of America. USA had a common law legal system. The mixture of common and civil law systems lead to a misinterpretation of laws, because all other codes were written in different languages. That is why, Edward Livingston in 1808 created a â€Å"Louisiana civil code†, which was approved by the major advocates of common law. In 1825 the Louisiana civil code was modified by adding missing force and was organized similarly with French Civil Code. The third civil code was evolved in 1870. The complete edition of all three codes was published in 1938. Starting from 1976 Louisiana’s State University is now responsible for the Louisiana civil code. Another striking example of the mixed of jurisdictions, would be Quebec. For a long time before being ceded by the Great Britain, Quebec was the part of France, and called le Canada. This means that in Quebec was under French Civil Legal system. After cession with Great Britain, the legal systems got mixed, and this lead to a confusion of the applicable law. The French population boycotted the new English law. To make some clarifications were made by creating a Quebec Act 1774, which combined both civil and common legal systems. In 1791 The Constitutional act divided Quebec into Upper Canada, with common law system and Lower Canada with civil law. Nowadays Canada still has a mixed jurisdiction The mixed jurisdiction is, in my opinion, a myth, but many countries are trying to reach the convergence between these two main legal systems. As I stated before, some countries already have mixed jurisdiction, but this mixture often leads to some misunderstandings and confusions to the legal authorities of the country. Convergence theory is a myth, but as long as developed countries will try to mix both of these legal systems, it can become reality. Bibliography Books: 1. De Cruz, P. , (1999).

Enzyme Kinetics Laboratory Report

Enzyme Kinetics Laboratory Report How the changes in substrate concentration (PNPP), changes in temperature, changes in pH and the presence of an inhibitor (phosphate ions) effects the rate of reaction of the reaction between PNPP and water catalysed by the enzyme acid phosphates which produces PNP and phosphate as its products . Using spectrophotometer to measure the absorbance of the products formed through hydrolysis of substrate. Abstract: The purpose of this scientific paper was to replicate earlier findings of experiments in enzyme kinetics and to see if enzyme behaviour and activity is influenced by 4 factors- change in substrate concentration, temperature, pH and the presence of a competitive inhibitor. In the first section where the substrate concentration was altered whilst the enzyme concentration was kept constant the relationship was found to be hyperbolic this can be explained using the Michaelis -Menten equation and the Lineweaver burk plot which was also used to obtain Km values of 0.25 and Vmax values of 0.12UNIT. The increase in [S] increased the rate of reaction at first but when [S] too much the initial velocity started to decrease. The increase in temperature led to a general increase in the initial velocity until the temperature reached 347 K where the enzyme denatured. The optimum temperature of the reaction was in the range 310 K- 323.2 where the rate increased at its fastest. The third section was the effect of pH on the enzyme activity. The optimum pH of the reaction was 5.5. This pH gave the highest reading of absorbance which means that the rate of hydrolysis was at its highest. Finally the last section of the experiment was the effect of competitive inhibitor on the rate of reaction. The investigation showed that the inhibitor used (phosphate ions) was a non-competitive inhibitor. The inhibitor did lower the initial velocity of the reaction when it attached to the enzyme at random. Introduction: This laboratory report is on the topic of enzyme kinetics, previous work in this particular field was carried out in the 1700s, when biological catalyst enzymes were discovered and studied. As understanding of enzymes increased scientist carried out basic laboratory experiments such as the conversion of starch to sugar by saliva to increase their understating of enzymes and how they function. However the first actual incident where enzymes were understood in detail was in 1897-by Edward Buchner .Since then on, till this period of time factors which effect the velocity/ rate of reaction and enzymes have been studied widely by many scientists globally. The modern scientists have a deep understanding of enzyme kinetics. The purpose of this laboratory report is to confirm previous findings covered in various sources of scientific literature and journals. Enzymes are often described as organic catalysts which increase the rate of reaction of a bio-chemical reaction ( David L.Nelson etal 2008). Enzymes increase the rate velocity of various reactions that occur in a biological system such as the mammalian digestive system. Enzymes can have functions including transfer, synthesis or breakdown of molecules. It is important to mention that enzymes are proteins which speed up the rate of reaction without being used up themselves i.e. they are reusable. Enzymes have a very specific active site which is complementary to a specific substrate 3 dimensional structure. The specificity is due to the complementary hydrophilic/hydrophobic charge, electrical charge and shape of active site on the enzyme. The binding of an enzyme with an specific substrate produces an enzyme substrate complex (ES).The rate at which the enzyme substrate complex is formed is dramatically increased or decreased in changes in substrate concentration, temperature, pH and presence of an competitive inhibitor the effect of these 4 factors on the enzyme activity is known as enzyme kinetics (Jeremy M. Berg etal 2006).Enzymes work on the concept of transition states. Transition state of enzymes is the phase where the substrate is not a yet a product and not a substrate. Enzymes reduce this phase .The difference between the free energy of the reactants and the free energy of the transition state is the activation energy (Ea).The minimum energy required for a success full reaction to occur. Enzymes speed up the rate of reaction by lowering the activation energy barrier. A typical enzyme substrate reaction can be simplified and be written as: The enzyme studied in this investigation was acid phosphatase. This enzyme can be identified by its Enzyme Commission Number (EC number) which is 3.1.3.2. Now I will briefly discuss the enzyme kinetic properties of acid phosphatase. The enzyme acid phosphatase catalyses the removal of phosphate group from organic molecules. Its primary mechanism of action is to bring a substrate molecule into contact with a molecule of water .This results in catalysis and the removal of phosphate group. Finally an hydroxyl group is attached to the substrate molecule. An example of this is the reaction shown below. This reaction was studied in this laboratory investigation. Acid phosphatase p-nitrophenylphosphate (PNPP) + water phosphate + p-nitrophenol(PNP) In the reaction above PNPP is the synthetic substrate, which is described as chromogenic.At. At high purity this compound is completely colourless. PNPP is hydrolysed by the enzyme acid phosphatase this produces phosphate and PNP. The product produced is yellow and can be measured using a colorimeter. The first part of the investigation concerns the effect of substrate concentration on the rate of reaction. I predict and expect that at an increase in substrate concentration (PNPP) will lead to an increased rate if reaction/initial rate. The reason for this is that an increase in substrate concentration increases the chances of a successful collision occurring between the enzyme and substrate increasing the likelihood of ES complex and product (PNP) formation results in an overall increase rate of reaction. This will produce a fist order reaction on a graph. However it is important to mention that at high substrate concentration the enzyme will be fully saturated this will reduce the rate of reaction as the there are too many substrate than enzymes. On a graph this would show a plateau. The maximum velocity of the reaction or the Vmax would be expected to be close to this region. Therefore I predict to see a hyperbolic relationship on a graph. Section B of this investigation concerns the effect of temperature on the rate of reaction. I would exepcet to find that an increase in temperature would result in an increase in the rate of reaction. The reason for this phenomenon is that as there is increase in kinetic energy being applied to enzymes and substrates it increases the chances of collision occurring so more product (PNP) is formed per unit time. However I also believe that temperatures above 50 -70 degrees Celsius would denature the enzymes active site and the 3 dimensional structures. At this stage the enzyme will not be complementary in shape to the substrate. This would mean that no reaction can be completed so the rate of reaction will decrease. It is important to state that the enzyme is going to have an optimum temperature at which the ES complexes and products are made at the fastest velocity. The increase in temperature increase the amount of molecules which have higher energy than the Ea barrier this in turn increases the amount of molecules which can react increasing the rate of reaction or initial velocity. I believe the optimum temperature is going to range between 20-40 degrees Celsius. The third part of this lab report is based on the effect of pH on the rate of reaction again I believe that at extremes of pH such as acidity or alkalinity will affect the rate of reaction. This may cause the enzymes structure to denature and will cause a lower rate of reaction and lower rate of product formation because the enzyme will not be complementary to the substrate. I would expect this enzyme to have a low optimum pH of around 5-2 as it is acid. Finally the last section of this investigation concerns the effect of a competitive inhibitor (phosphate ions) on the rate of reaction. Inhibitor in this case the phosphate ions will compete with the actual substrate PNPP for the active site of the enzyme acid phosphatase. These inhibitors can only attach to the active site of the enzyme due to their complementary properties. The concentration of the inhibitors will be kept constant and the concentration of the substrate PNPP will be altered. I believe that as the concentration of PNPP increases the rate of reaction will increase this is because the PNPP can out- compete the competitive inhibitor and reverse the effect of the inhibitor. Materials and Methods: All procedures were carried out as described in the lab schedule. No alterations were made to any of the procedures carried out throughout the experiment. Discussion: The first section of this lab report relates the effect of substrate concentration on enzyme activity. I shall briefly discuss and explain what my data shows and means. Graph 3 which is the graph of Michaelis Menten of collected data. The relationship between the rate of an enzyme-catalysed reaction and the substrate concentration can be describes as hyperbolic. The graph and tables 2 show that as the concentration of substrate (PNPP) increases from 0.00 Mmols to 0.20 Mmols of substrate the initial velocity or the rate of reaction shows an increase in too. The relationship can be describes as fist order as the [V] rises almost linearly with the increase in [S]. However after the concentration increase from 0.20- to 3.00 Mmols the initial velocity shows a gradual increase and then gradually levels of or slopes here graph shows 0 order relationship. This supports the prediction I made in the introduction. The graphs indicates that as the concentration of substrate increase the rate of reaction increase this is because of the increase chances of a collision between a substrate and an enzyme. This in turn increases the rate at which ES and P are formed. However after the concentration increase after 0.20 3.00 Mmols the rate stars to level off. The reasoning behind is this is that there are too many substrates than compared to enzymes an all enzymes are described to be fully saturated .At this phase the reaction is at its Maximum velocity and cannot increase in rate unless more enzymes are added therefore enzyme concentration is the limiting factor. I can tell that the data I collected from the experiment in the lab is accurate and valid as the graph which compares the theatrical data and the collected data show similarities in the trend line the Vmax the km and as well as the points and there is no anomalous data point on either of the 3 graphs. My findings support the findings of many previous investigations and journals as the graphs show a similar relationship as to the findings to previous work. The implications of this investigation can be used widely to determine the Vmax and KM. These values can be used for medical purposes since the enzyme acid phosphatase is manufactured by the body to remove phosphate groups. The limitation of Michaels Menten plot is that the Km and Vmax cannot be accurately determined. Therefore a Lineweaver burk plot is plotted. The Lineweaver burk plot shows that the KM and Vmax are very similar to the ones from the Michaelis Menten plot. Finally KM is an approximate measure of the affinity of an enzyme for its substrate.A small value of KM indicates a high affinity of the enzyme for the substrate. From my graphs (1 +2) I can tell that the KM was 0.24 and therefore small. This means that the enzyme acid phosphatase has a high affinity for the synaesthetic substrate PNPP. This means that small concentration of substrate PNPP is enough to run the reaction at half of maximum velocity (1/2 Vmax). The next section of the investigation concerns the effect of temperature on the rate of reaction. I predicted an increase in temperature will increase the rate of reaction or the initial velocity of the e reaction until the enzyme denatures and the protein sequence becomes damaged an unravels. The actual reason for why the protein sequences unravel is that the protein has too much kinetic energy and the amino acids vibrate and this causes the non covalent forces to be weakened. There is an increase in the rate of reaction as the temperature increases from 278 -323 K the increase is almost linear. However after the temperature 323 K-to 347 K the enzyme denatures and unravels. This is proved by the last point on the graph which doesnt fit the line of best fit. Overall the graphs and data all prove my predictions correct. There is no other anomalous data present. The third section concerns the effect of pH on the rate of reaction. As we have discovered before the enzyme used was acid phosphatase so the pH at which it works at best the optimum temperature will be in the acidic pH regions. I can confirm from my graph that the optimum pH of the reaction is in the region 5-5.5 which is indeed acidic. pH of 5.5 gives the highest absorption value, this therefore means that the rate of hydrolysis was at its fastest. A possible explanation for the change in the experimental design is that the pH may denature the enzyme if the enzyme was added first the active site and 3 dimensional shape of the enzyme could be altered at extremes of pH such as 2 which is quite acidic. The pH does not affect the substrates 3 dimensional structure in the same ways as the enzymes. Therefore to obtain valid results /data the design for this part of the experiment was slightly altered. pH has a very strong effect on enzyme activity .This is because enzymes work on the basis of mechanisms such as induced fit hypothesis and lock and key . The enzymes have a specific active site due to the complementary 3 dimensional active site with the substrate. According to the induced fit hypothesis the enzyme can undergo some change in the 3- dimensional structure in order to fit the substrate. However a change in pH changes the enzymes active site structure. An increase in H+ ions can change the active site structure due to the fact that h+ ions can interfere with any polar molecules on enzymes protein structure. Amino acids side chains can be protonated and may be damaged due to the extreme pH (concentration of H+ )this may result in the protein sequence to unravel which means that the active site is not complementary to the substrate and the rate of reaction decreases as no or little ES are formed which results in little products formed. The final section concerns the effect of a competitive inhibitor (phosphate ions) on the rate of reaction. From my graph I can tell that the inhibitor present was an non-competitive inhibitor. I can tell this by looking at the Lineweaver Burk plot where the trend lines cross the 1/Vmax intercept at different values but cross the 1/km intercept at the same values. This means that this type of inhibitor does not affect the KM but does lower the Vmax values. Non competitive inhibitor has the same effect as lowering the total volume of enzyme. This type of inhibition is reversible. It binds to a site away from the enzymes active site it denatures the active site so no other substrates can bind to the active site. This in turn lowers the rate of reaction and the rate at which products are formed. However this type of inhibitor also binds to the enzyme substrate complex I can therefore conclude that the non competitive inhibitor does lower the rate at which the products are formed.

Incorporating Farmers Knowledge in International Rice Research Essay

Incorporating Farmers' Knowledge in International Rice Research The longevity of many cultures can be attributed to their adherence to tradition, specifically subsistence practices. More likely than not, trying to push modern technology into these cultures will only result in disaster. Such is the case with the Green Revolution and the rice situation Stephen Lansing covered in The Balinese. It simply does not seem logical to disrupt traditional practices that have supported a culture for so long. There is a reason certain practices have been around for so long and that is because they work the best for certain people in certain locations. Sam Fujisaka supports this notion which is the basis for his article "Incorporating Farmers' Knowledge in International Rice Research." Fujiska's article describes his research done examining traditional farming techniques of the Claveria people of the Southern Philippines, so that their methods of rice farming may be used to improve research of agriculture. This article sets a good example for researchers of more developed countries who study such indigenous cultures. Rather than trying to see which modern technology from the "outside world" will best help these cultures, Fujisaka attempts to learn from these cultures' traditional methods to help improve the farming industry. Fujisaka's study of rice farming in the Philippines is much like Lansing's study in Bali, in that both cultures rely heavily on rice farming and both cultures suffered much the same from the effects of the Green Revolution. Thus, finding what improvements need to be made and how, is an important task that could help many people. Fujisaka began exploring these improvements by interviewing local Clave... ...ys best for everyone. This is a point that is necessary for people (specifically anthropologists) to bring into the light when dealing with other cultures. Understanding as much as possible about a culture is essential before attempting to get involved with their lives and, as Fujisaka shows, before getting their lives involved in others. He concludes "that the knowledge of farmers can be used first to identify and prioritise research issues" (139), and considering the respect for these cultures with which he conducted his research, Fujisaka's study can be considered more sound than most.

The Death March Essay -- War, World War II

Plan of Investigation A tactic used in past wars, and also categorized as a war crime, is known as the death march. These marches have often been criticized for being inhumane, and forcing enemy soldiers into â€Å"conditions primitive and unsanitary.† (51 Allen) Both of the death marches studied in this historical investigation occurred in World War II. The first is the Bataan Death March, inflicted upon Americans and Filipinos by the Japanese. The second case studied will be the forced movement of â€Å"undesirables† (i.e. Jews, Homosexuals, blacks, gypsies, etc.) in the numerous Nazi death marches. How and why did the reasons and strategies for the Bataan Death March compare with those of the Nazi death marches? Both cases will be summarized and then analyzed. The justification for these marches will therefore lead to deciphering the extent that these marches helped the instigating countries, and what war would have been like without them. Primary sources, such as â€Å"Aband oned on Bataan,† along with secondary sources such as â€Å"Double Victory† will be utilized to fully comprehend the differences of the two marches. Summary of Evidence 1) Bataan Death March When General MacArthur of the United States surrendered, the Japanese were not prepared for the immense number of US and Filipino prisoners. Their justification for their war crimes comes from their culture. The Japanese were instilled with the idea of fight or death. Surrendering was not an option to the Japanese, because it made one scum, and not even human. In the Japanese perspective, the American soldiers that surrendered had intentionally put themselves in this position. The Japanese did what they were taught; their cultural traditions allowed for the violence an... ...ese Lines in World War II. New York: NAL Caliber, 2009. Print.
