Siemens case study Example | Topics and Well Written Essays - 2000 words

Siemens - Case Study Example It is the commitment of companies, especially those that have a significant influence on the international market that ensures that efficiency is maintained. Efficiency is integral not only when it comes to using minimum resources to fulfill maximum needs, but is also pivotal when it comes to allocation of resources and their eventual distribution. In other words, the basic economic problem is seen to have its solutions within the confines of efficiency, and it is advantageous for the members of the world of commerce to ensure that the equilibrium of efficiency is maintained, both locally and internationally. Multinationals companies are seen as increasingly responsible for maintaining the equilibrium that would benefit all since their increased market share gives them greater influence in the arena of buying and selling. This is one reason why the use of bribes is heavily frowned upon by the international markets, especially when large multinational firms are involved. The use of br ibes is an act that disturbs the equilibrium of free trade, since they influence the decision power of individuals, prejudicing it to fall in the favor of the one offering bribes. Siemens, being one such multinational firm that possessed significant share of the global market was caught in the hurricane of media attention, international scrutiny and internal ratification policies when fraudulent actions were seen to be prevalent within the company. The Siemens executives were accused of paying six million Euros to another company in order to achieve the gas turbine contract in Italy. The accusation involved that the executives used the company funds to influence the decision of others. This accusation attracted the attention of the international media since it involved the transaction of such a large amount of money. Moreover, the reputation of one of the world’s largest companies was at stake. As a company that complies and abides by the restrictions and regulations of the f ree market, the bribe was seen as an act that harms the spirit of competition and free trade in the global market. Thus, Siemens was seen as the perpetual deviant of the global market. Subsequently, the fact that a multinational company such as Siemens is involved in financial embezzling had a negative impact on the brand. The executives accused of the embezzling were Andreas Kley and Horst Vigener. While they agreed that the transfer of six million Euros from Siemens to Enel did occur under their authorization, they defended their actions. These former managers said that their actions cannot be classified as an act of fraud since the financial transaction between Siemens and Enel was made solely and purely for the benefit of Siemens the company. They claimed that a bribe is an act that ensures personal gain, and signifies corruption that is intended to harm the company. However, their decision to transfer the amount to Enel was not for their own gain. Siemens would have gained imme nsely if the contract for the gas turbine had been awarded to them, and the managers were aware of this. The company hoped to earn 90 million Euros in addition to a firm footage in the Italian market. Thus, Siemens’ funds were not used to benefit anyone else, except Siemens the entity itself. Since neither employee benefitted personally from the funds transferred, both Kley and Vigener testified that they were innocent. The defenses they presented were to an extent

MANAGEMENT PROJECT - Research Paper Example The appraisal is conducted as part of the performance management process of the organization because how it is handled is what determines whether the organization is able to achieve its goals or not. It can further be said that a performance appraisal is an assessment and discussion of how an employee has performed in his or her work and this assessment is based purely on performance and not on the characteristics that are displayed by the individual employee. This process helps in the measurement of the skills that have been displayed and the things, which an employee has accomplished with as much accuracy and uniformity as possible. The understanding that is developed by the employee’s supervisor enables management to determine the abilities of individual employees and this ensures that they are placed in positions within Cathay Pacific which will further its growth and achievement of its goals. Furthermore, it is designed to help the company determine the areas whose performance needs to be enhanced as well as ensuring that the employees are provided with the opportunities that are necessary for the promotion of their professional growth. This process is done in methodical ways that gives the supervisors the opportunity to measure the payments that are made to their employees in comparison to the aims and objectives of Cathay Pacific. In addition, performance appraisal gives the supervisors the opportunity to make an analysis of the factors that determine how the employees perform over a certain period. A system helps the management of Cathay Pacific to be in a position where it is able to provide guida nce to its employees towards a path that will lead to their performing better in their jobs. In addition, while performance appraisal can be considered as an immensely important tool by supervisors to gain an understanding of the people who work under them, it is not necessarily the

S it more accurate to say that presidents adapt to the critical events Essay

S it more accurate to say that presidents adapt to the critical events that happen during their time in power, or are they more - Essay Example The United States, which is both the greatest economy and democracy in the world, has influenced the course of history of the world. It therefore provides a definite relationship between presidents and the historical occurrences. Among iconic presidents of the United States was Abraham Lincoln, the sixteenth president of the United States who served until his untimely assassination in 1865. The events in his tenure including his assassination depicted the influence that the presidents had in shaping the history of their times. He served during some of the most tumultuous times in the country. He led the country through the most historic constitutional, moral and military crisis. His contribution and time in office thus makes him the best president whose analysis may easily depict the role of presidents in influencing the history of their tenures (Burkhimer, 2003). Additionally, he provides an effective basis of comparison with some of the recent presidents such as the incumbent presi dent Barack Obama and George Bush among many others who also served during some of the most tumultuous times in the history of the country. Presidents are always at the help of politics. They are influential people who readily access all the power brokers in a country. The American politics consists of a set of members of parliaments and senators all of who are influential in managing the domestic politics in the different states. The presidents on the other hand has influence over such and enjoy vast constitutional power to institute policies but with the consent of such politicians. Born and raised in a poor American family at a time that capitalism and slave trade was at the pick, Abraham Lincoln educated himself and later joined politics. He lost a senate seat in 1858 for maintaining a hard line rejection for the plan to expand slavery. He was determined to end slavery in the country. Though not a Member of Parliament, the president influenced the lawmakers during his tenure as the president of the United States thus succeeding in emancipating the African Americans. The liberation of the black society in the United States was one of the greatest historical occurrence in the country that earned Abraham Lincoln both friends and foes in equal measure thus possibly leading to his assassination. His role in liberating the African Americans and safeguarding the rights of the marginalized society to take part in election in the country’s constitution was a self-depiction of the influence that presidents have over the historical occurrences. Slave trade had employed millions of American capitalism merchants; it had necessitated the agrarian revolution thus developing the country’s economy. Vouching for the abolition of slave trade and developing an equal American society in which the African Americans would enjoy equal rights as their white counterparts was therefore a major historical occurrence. The success to end slavery was not a timely occurrenc e; it was not any time coming. President Abraham Lincoln worked hard and tried all he could to convince and black mail some of the members of parliament to accept and pass the bill that would change the country’s constitution. The desire to free the society had cost him his political career in the past but his determination finally bore fruits thus possibly resulting in his assassination. The life and works of president Abraham Lincoln portrays the influence tha

Phenomenon Of Grandparent Becoming Parent Essay FIGURE FOR GRANDCHILDREN   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Since 1980, there have been dramatic increases in children living with and being cared for by their grandparents. In 1980, 2.3 million children were living in with their grandparents. By 1997, there were 3.9 million children living in that situation. The 2000 U. S. Census has reported 4.5 million children living in grandparent-headed homes. The 2000 Census also counted, for the first time, 2.4 million grandparents who are responsible for the basic needs of their grandchildren who are living with them. REASONS WHY GRANDPARENTS ARE RAISING THEIR GRANDCHILDREN   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Given the statistics above, it can be assumed that more and more grandparents have to play parenting roles for their grandchildren. There are a number of reasons why the statistics continue to rise: The American Association of Retired Persons’ (AARP) Grandparent Information Center states that the most common reason is substance abuse. Drug and alcohol problems are causing parents to be unable to raise their children. Teenage pregnancy is also one reason why grandparents come to raise their grandchildren. Parents who marry and give child at a very young age are often not yet emotionally prepared to take care of their children Illnesses – parents have mental illness or have contacted some other diseases like HIV/Aids. Incarceration-parents are imprisoned or are under detention Child abuse or neglect-the child have been physically abused or are totally neglected by their parents Domestic violence-the parents are often hurling verbal or physical abuse against each other and the child suffers from trauma Death of one or both parents Military deployment- grandparents are called to step in when one or both parents are deployed in military service and are unable to care for their kids Poverty or joblessness   Ã‚  Ã‚   EMOTIONAL BENEFITS   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   A majority of grandparents who raise their grandchildren report experiencing a great purpose for living. Providing care for grandchildren helped them to feel young and inactive. Other rewards include A chance to raise a child differently A chance to nurture family relationships. Family ties and values are preserved. They are able to receive love, affection, and companionship from their grandchildren. Children raised by grandparents tend to be less rebellious and are more understanding and appreciative. To many of the grandparents raising their grandchildren, their sacrifices are more than worth it. It is clear that despite the problems, most grandparents derive satisfaction from acting as parents to their grandchildren. Caring for their grandchildren can be positive and rewarding. Grandparent bring the benefit of experiences and perspective. They can also provide important stability, predictability.   And they can be a healthy role model for their grandchildren. OTHER PROBABLE BENEFITS   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Grandparents can ask for legal arrangements so that they can have full custody, temporary custody, or they can obtain the status of being a foster parent. When custody is established by the law, they will have a measure of legal security and can gain rights and benefits for them and their grandchildren. The Children’s Health Insurance Program (CHIP). Each state has a CHIP which pays for doctor visits, hospital stays, shots, and medicine. Financial Aids A child may be legible to get money from the state’s Temporary Assistance for Needy Families (TANF) Program. These families may qualify for food stamps. The child may qualify for Child Tax Credit and the grandparent may qualify for the Earned Income Tax Credit. Both programs can give them extra cash at tax time. Grandparents can ask the school guidance about applying for free hot meals for their grandchildren. REFERENCES Bryson, K. Casper, L.M. (1998). â€Å"Co-resident \Grandparents and their Grandchildren.

Handedness and Lateralization

Handedness and Lateralization Handedness and Lateralization Cortical Organisation and Lateralization Of The Brain In Handedness And Dominance According to Annett most people in our society define handedness as the hand that you use for writing (1970). Researchers define handedness as the hand that performs faster or specifically on physical tests. Paul Broca (1979), suggested that a persons handedness was opposite from that specialised hemisphere (so a right-handed person probably has a left-hemispheric language specialization). However, a majority of left-hemispheric brain specialise for language abilities. Many researchers have try to this correlation between handedness and brain lateralisation. The key reason that hand-brain link is important and is an accepted methodology is that clinicians use handedness as a marker for brain lateralization. Language is a distributed cerebral network with differences in area involvement that relate to specific language functions (Frith et al., 1991). Vital regions in network lateralize to one hemisphere and determine lesion (Ojemann, 1991). In most people this lateralization is to the left. The only consistent information on the variability of hemispheric control between individuals are aphasias following a stroke or hemispheric inactivation by procedure in patients with brain lesions (Wada and Rasmussen, 1960). Pertaining to the unevenness of language control there is a chance of functional hemispheric reform (Rasmussen and Milner, 1977). It assumes that variation from left hemisphere language power is related to a difference like left-handedness. In right-handed subjects there is puzzling correlation of verbal language and hand dominance, both confines to a small area to the left hemisphere (Mayeux and Kandel, 1991). The actual variability of language lateralization in the general popu lation is practically unknown. Evaluations in a representative number of healthy subjects do not exist because, in the past, no technique was available to determine language lateralization effectively and non-invasively. This lack of information has hampered the assessment of language disturbances. There is an ongoing debate on the role of the right hemisphere in recovery from aphasia after left hemispheric strokes (Weiller et al., 1993Go; Heiss et al., 1997Go; Mimura et al., 1998Go). Particularly, in retrospective evaluations it would be important to know how many patients with left hemispheric strokes and transient disturbance of language can be expected to have been right hemisphere language dominant and to have suffered speech impairment due to other, more unspecific causes like decreased vigilance. Moreover, knowledge concerning the exact incidence of right hemisphere language dominance in healthy righthanders would be important for functional neuroimaging studies. Here, due to lack of information, researchers often need to rely on the assumption that restricting examinations to healthy right-handers will control for a possible variability in hemispheric dominance. Recently, a simplified functional imaging technique, functional transcranial Doppler-ultrasonography (fTCD) has become available (Aaslid, 1987Go; Hartje et al., 1994Go; Silvestrini et al., 1994Go; Rihs et al., 1995Go). It allows determination of hemispheric dominance in individual subjects in an effective, reliable and non-invasive way (Deppe et al., 1997Go; Knecht et al., 1998). This technique has now made it possible to establish the variability in the side and degree of language dominance in a representative number of healthy subjects. fTCD measures cerebral perfusion changes related to neuronal activation in a way comparable to functional MRI (fMRI) and 15O-PET (Kuschinsky, 1991Go; Jueptner and Weiller, 1995Go; Deppe et al., 1997Go, 1998Go). fTCD makes it possible to compare perfusion changes (by measuring blood flow velocities) within the territories of the two middle cerebral arteries (MCAs), which comprise the potential language areas (van der Zwan and Hillen, 1991Go). It thus provides an operational index of laterality which, in many respects, resembles the one obtained by the intracarotid amobarbital procedure (Wada test) (Wada and Rasmussen, 1960Go). Determination of language lateralization by fTCD matches precisely both the results of fMRI and the Wada test with concordance in every single case (Deppe et al., 1998Go; Knecht et al., 1998aGo). As in many previous studies of this kind, word generation was chosen as an activation paradigm because it is one of the most effective measures of language production (Neils-Strunjas, 1998Go). On this basis language dominance was determined in a total of 188 healthy subjects. Left-handers were excluded from the study because of possible confounding effects of handedness on hemispheric dominance (Kimura, 1983Go). A careful history for brain damage in the prenatal period or in infancy was taken in order to exclude subjects with possible plastic reorganization of hemispheric dominance after brain lesions (Rasmussen and Milner, 1977Go). The work was part of the Munster functional imaging study on the variability of hemispheric specialization in health and disease (Deppe et al., 1997Go; Knecht et al., 1998aGo, bGo). Hemispheric language dominance was assessed in 188 healthy volunteers with 111 females (mean age 26  ± 5.5 years, range 17-50 years) and 77 males (mean age 27  ± 3.7 years, range 21-40 years). Subjects were excluded if, on a standardized questionnaire, they reported delayed or disturbed language development or a history of other neurological disorders, particularly perinatal asphyxia or kernicterus, head trauma, loss of consciousness, epileptic seizures, meningitis or encephalitis. They were further required to have successfully completed the equivalent of high school (`Realschule or `Gymnasium). Right-handedness was assessed by a handedness index in the Edinburgh Inventory of greater than 30% (Oldfield, 1971Go). Left-handers were excluded from the study, as were right-handers with a score for right-h andedness lower than 30%, because, due to the small number of these subjects, an adequate evaluation of the effect of handedness on language lateralization would not have been possible. Approximately 75% of the subjects recruited had an index of more than 80% right-handedness. All subjects gave informed consent to participate in this study, which was approved by the Ethics Committee of the University of Mà ¼nster. Assessment of hemispheric language dominance was performed by a standardized fTCD technique (used in a number of previous studies) and a word generation task, validated by direct comparison with the intracarotid amobarbital injection and fMRI (Knecht et al., 1996Go, 1997Go, 1998aGo, bGo; Deppe et al., 1997Go, 1998Go). Briefly, subjects were presented with a letter on a computer screen 2.5 s after a cueing tone. Silently they had to find as many words as possible starting with the displayed letter. For fTCD an activation paradigm strongly based on verbal fluency was used, corresponding to the fields of reported female superiority (Basso et al., 1982Go; Pizzamiglio et al., 1985Go). Task performance was controlled by instructing the subjects to report the words after a second auditory signal following 15 s after presentation of the letter. All words had to be reported within a 5-s time period. The next letter was presented in the same way after a relaxation period of 60 s. Letters were presented in random order and no letter was displayed more than once. `Q, `X and `Y were excluded because very few words have these as initial letters. Changes in the cerebral blood flow velocity (CBFV) in the basal arteries were measured as an indicator of the downstream increase of the regional metabolic activity during the language task. Dual fTCD of the MCAs was performed with two 2 MHz transducer probes attached to a headband and placed bilaterally at the temporal skull windows (1Go). Details of the insonation technique, particularly the correct identification of the MCA, have been published elsewhere (Ringelstein et al., 1990Go). The spectral envelope curves of the Doppler signal were analysed off-line with the fTCD software AVERAGE developed by one of the authors (M.D.) (Deppe et al., 1997Go). 1 Schematic diagram of the way language lateralization was determined. Perfusion increases and therefore neuronal activation during word generation were assessed in the vascular territories of the left (marked in red) and right (marked in green) MCAs, which comprise the language areas. This was achieved by fTCD measurements of the CBFV changes in these arteries. Systemic effects were eliminated by calculating the differences in perfusion changes between sides. Averaging the responses over 20 repetitions (on average) in each individual made the results highly reliable. (For details, see Deppe et al., 1997.) After automated artefact rejection, data were integrated over the corresponding cardiac cycles, segmented into epochs which related to the cueing tone and then averaged. The epochs were set to begin 15 s before and to end 35 s after the cueing tone. The mean velocity in the 15-s pre-cueing interval (Vpre.mean) was taken as the base-line value. The relative CBFV changes (dV) during cerebral activation were calculated using the formula: dV = [V(t) Vpre.mean] x 100 / Vpre.mean where V(t) is the CBFV over time. Relative CBFV changes from repeated presentations of letters (on average 20 runs) were averaged time-locked to the cueing tone. The number of repetitions was less than 22, because no letter was presented more than once during the word generation task. A functional TCD laterality index LIfTCDwas calculated using the formula: Statistics The Kolmogorov-Smirnov test was used to assess the hypothesis that laterality indices in males and females were drawn from different populations. Unlike the parametric t-test for independent samples or the Mann-Whitney U test, which tests for differences in the location of two samples (differences in means, differences in average ranks, respectively), the Kolmogorov-Smirnov test is sensitive to differences in the general shapes of the distributions in the two samples, i.e. to differences in dispersion and skewness (Spence et al., 1990Go). The Mann-Whitney test for equivalence (Wellek, 1996Go) was employed to confirm equivalence of laterality indices in men and women. A significant result in this test provides a strong positive measure for a lack of gender differences in laterality indices. We tested the null hypothesis H0: |P[LImale > LIfemale] 1/2| >={varepsilon}versus the alternative hypothesis of equivalence H1: |P[LImale > LIfemale] 1/2| In six of the 194 right-handed subjects determination of language lateralization was not possible due to lack of a temporal bone window, i.e. inadequate ultrasonographic penetration of the skull by the ultrasound beam. In the remaining 188 subjects (59% females, 41% males) the overall distribution of language lateralization was bimodal with 7.5% being right hemisphere and 92.5% left hemisphere language dominant (2Go). The distribution of language lateralization was equivalent in men and women (3Go). The Kolmogorov-Smirnov test did not detect any significant differences between females and males in the overall distribution (P > 0.05). In the subgroup of left hemisphere language dominant subjects, the Mann-Whitney test for equivalence showed equivalence with P The average number of words found during the activation task per letter presented was not statistically different between men and women (Mann-Whitney U test, P = 0.81) or subjects with left or right hemisphere language dominance (Mann-Whitney U test, P = 0.26). It was also independent of the index of lateralization (correlation coefficient r = 0.027). These are the first data on the natural distribution of language dominance in a large series of healthy right-handed subjects. They demonstrate equivalence of language lateralization for word generation in males and females, and they suggest that 1 in 13 healthy right-handed subjects is right hemisphere dominant for language. Methodology There is debate whether language can be treated as a separate mental faculty or should be approached as part of a more general cognitive system (Fodor, 1983Go). Moreover, language comprises receptive and expressive aspects and is intertwined with prosody, memory and attention (Knecht et al., 1996Go; Binder et al., 1997Go). Therefore, the assessment of language lateralization based on a single activation task provides just one index of the interindividual variability in language processing. This approach can nevertheless serve as a first step in elucidating the factors underlying the diversity of large scale neural language organization. fTCD lends itself to determination of hemispheric language dominance. The index of lateralization obtained by fTCD based on word generation is very reliable and closely corresponds to (i) the outcome of the intracarotid amobarbital procedure and (ii) the index of lateralization obtained by fMRI (Deppe et al., 1998Go; Knecht et al., 1998aGo). Other techniques like head turning, event-related potentials, transcranial high frequency magnetic stimulation or the dichotic listening test used for the evaluation of language dominance have so far failed to provide results that are reproducible and in sufficient concordance with the intracarotid amobarbital procedure (Bryden and Allard, 1981Go; Jancke et al., 1992Go; Jennum et al., 1994Go; Segalowitz and Berge, 1995Go; OLeary et al., 1996Go; Hugdahl et al., 1997Go). Unlike the intracarotid amobarbital procedure and as opposed to brain lesions, functional imaging techniques including fTCD assess brain activation and not inactivation. They are set to determine the location and relative amount of the maximal activation while diffuse or bilateral activations are cancelled out. Thus, fTCD is insensitive to a lesser activation in the contralateral hemisphere. Moreover, fTCD cannot determine whether an activated region during a task is a critical region that, when damaged, will result in a loss of that particular function. This shortcoming holds for all functional imaging techniques. However, the fact that determination of language lateralization by fMRI and fTCD correspond closely to that determined by the intracarotid amobarbital inactivation suggests that activated regions match critical regions and therefore provide essential information on the risk for language loss (Desmond et al., 1995Go; Binder et al., 1996Go; Knecht et al., 1998aGo). Sex Fuelled by the general interest in `la petite diffà ©rence, the lack of information about the natural distribution of language dominance has led to far-reaching speculations about possible differences in language lateralizations between the sexes. This discussion has been characterized by a high acceptance for positive results. Thus, despite considerable data to the contrary, there is a strong belief that language in women, on average, is less lateralized than in men (Bakan and Putnam, 1974Go; Levy and Reid, 1976Go; McGlone, 1980Go; McKeever et al., 1983Go; Hough et al., 1994Go; Rugg, 1995Go). The idea of an increased bilaterality in women has received support by a recent fMRI study in 19 males and 19 females (Shaywitz et al., 1995Go) in which activation related to a rhyming task was found to be more bilateral in women than in men. It has been conjectured that an increased bilaterality of language in women would lead to a decreased susceptibility to unilateral infarctions explaining a greater male than female proportion of aphasics (McGlone, 1980Go). Kertesz and Sheppard then showed that aphasias were as frequent in males as in females, as long as sex differences in the incidence of infarcts were taken into account (Kertesz and Sheppard, 1981Go). Similar results were obtained in a more recent epidemiological study (Pedersen et al., 1995Go). Recently, using fMRI, Frost and colleagues found no differences between sexes during a language comprehension task when group averages were compared (Frost et al., 1999Go). Our data provide the first direct evidence that language lateralization during word generation in men and women is also equivalent in variablity. In fact, they not only show a lack of significant differences but they positively demonstrate significance of equivalence in healthy subjects even though this finding is based on a word generation task, i.e. a field of reported female superiority (Kimura and Harshman, 1984Go). Equivalence of hemispheric lateralization between sexes during word generation does not exclude gender di fferences in subfunctions of language like rhyming, which we did not investigate. As was pointed out before, such a difference has been reported by Shaywitz and colleagues in a small series of subjects examined by fMRI (Shaywitz et al., 1995Go). However, in line with our results, these researchers did not find gender differences in other language tasks. Right hemisphere language dominance The predominance of right-handedness and left hemisphere language lateralization has led some theorists to suggest that a gestural system of communication with dominance of the right hand provided the neural architecture for vocal articulation in human evolution (Hewes, 1973Go; Kimura, 1987Go). If indeed handedness and language were coupled because they share the same neural resources, then any deviation from this pattern would have to be pathological. Right hemisphere language dominance in right-handers or left hemisphere language dominance in left-handers reported from the intracarotid amobarbital procedure does not challenge this view, because this procedure is only performed in patients with brain pathology. However, the present findings in healthy subjects indicate that even under natural conditions the association between handedness and language dominance is not an absolute one. Because 75% of subjects were strongly right-handed (>80%) and the remaining had handedness indices o f >30%, the effect of the degree of handedness on language lateralization could not be evaluated in the present study. Comparison of left- and right-handers will be necessary to test whether a relative association between handedness and language dominance exists in healthy subjects. The extreme argument could be put forward that all of our presumed healthy subjects with right hemisphere dominance must have suffered covert brain damage resulting in a shift of language into the right hemisphere. A similar argument has been made to explain left-handedness in healthy subjects (Coren, 1990Go). We believe that covert brain damage was unlikely. The medical history in all subjects was unrevealing and the scholastic achievement was similar. The average number of words produced during the task did not differ between subjects with left or right hemisphere language dominance and the pattern of language lateralization variability was bimodal with maxima for left- and right-hemisphere dominance (2Go). If there had been subclinical damage to language relevant areas in the left hemisphere resulting in a shift to the right, one would have expected impaired word fluency and more cases with little lateralization because of a bilateral representation of language functions. This was not the case. We therefore suggest that right hemisphere language dominance is not a pathological but a natural phenomenon. Previous estimates of `atypical right hemisphere language dominance were either based on the results from the intracarotid amobarbital test in patients evaluated for resective neurosurgery or on the occurrence of `crossed aphasia, i.e. aphasias after right hemispheric lesions. In patients with epilepsy submitted to the intracarotid amobarbital test the number of right-handers with right hemisphere language dominance was 4% in a large series and rose to 12% when a left hemisphere lesion was defined (Rasmussen and Milner, 1977Go). Because the Wada test is only performed in patients with brain lesions, which are often associated with a secondary transfer of cortical functions from the damaged to the intact hemisphere, these numbers cannot be extrapolated to healthy subjects (Helmstaedter et al., 1994Go). By evaluation of stroke-patients with crossed aphasia, the incidence of right hemisphere language dominance in right-handers has been inferred to be between 1 and 2% in the majority of series (Gloning, 1977Go; Borod et al., 1985Go; Kertesz, 1985Go). On the one hand, this low estimate of right hemisphere language dominance in previously healthy subjects made aphasias in right-handers after right-sided lesions seem an exceptional event and has resulted in almost 100 reports on `crossed aphasia in the last 30 years. On the other hand, difficulties in the assessment of language performance due to physical exhaustion and deficits in sustained attention in the early stages after stroke and reorganizational restitution in the later stages may have facilitated an underdiagnosis of aphasia in right hemispheric stroke patients in many studies. Not every patient with a cerebral infarction in the respective language dominant hemisphere will suffer damage of the language areas and become aphasic. The overall rate of aphasia due to stroke has been found to be 38% in the acute state and 18% at discharge from the hospital (Pedersen et al., 1995Go). Reasoning from the effects of brain activation to the effects of brain lesions is problematic but results from activation studies may be conceptually useful to the understanding of lesion-deficit variability in the clinical context (Willmes and Poeck, 1993Go). In a single recent study on 880 stroke patients it was reported, in passing, that of right-handed aphasics 9% had right hemispheric lesions (Pedersen et al., 1995Go). In a study on language deficits in servicemen who had suffered penetrating brain wounds, 18% of the aphasics had suffered right hemispheric lesions (Mohr et al., 1980Go). However, here the possible effects of diffuse brain damage by the impact of a bullet and the effect of variable handedness pose methodological limitations. Our cohort was similar in age to these soldiers. We found an incidence of 7.5% of right hemisphere dominance in our activation study of healthy subjects. This combined evidence suggests that about 1 in 13 previously healthy right-handed patients with a right hemispheric infarction could be at risk of suffering language impairments becaus e this is the hemisphere dominant for word generation. Conversely, after left hemispheric infarctions right-handed patients, who in retrospective evaluations seem to have recovered well from language disturbances, and on fMRI or PET may even show language related activation in the right hemisphere, may do so because they had been right hemisphere language dominant to begin with. Presently, we do not know the relevance of the extent of language lateralization by fTCD. Low indices of lateralization indicate that there is a bihemispheric activation during word generation. Although reported in studies based on the Wada test, bilateral language representation in stroke patients has probably been neglected because persistent aphasia in these subjects may only occur after bilateral damage (Benbadis et al., 1995Go). This is very rare and patients rarely survive. However, subjects with low indices of lateralization may be the ones who, after unilateral damage of traditional language regions, do not show marked aphasia and recover well by further recruitment of the intact hemisphere.

Identifying Heroes: The Godfather and Pulp Fiction Essay -- essays res

Identifying Heroes: The Godfather and Pulp Fiction The form of Classical Hollywood films is, first and foremost, invisible. In a Classical Hollywood film, the narrative is foremost, and style serves the narrative. Camera angles, lighting and editing patterns such as the shot/reverse-shot pattern aim to give us the best possible perspective on the unfolding events(1). These events are arranged in a strongly causality-oriented linear narrative, with one event causing the next. This narrative is arranged around a central, active protagonist, whose decisions and actions are the key to the pattern of cause and effect that drives the story(2). This pattern seems so logical, so natural, that the audience of the classical Hollywood film is supposed to feel that they are receiving the material without the mediating intervention of the filmmaker. The link between heroes and the spectator under this model is therefore one of relatively unproblematic identification. Even films that featured anti-social heroes, such as the thirties gangster genre , modified the pattern only through imposing the strongly moral, tragic sequence of rise and fall; the audience's identification remained firmly with the central protagonist(3). Such a situation, under these assumptions, puts the audience in an apparently perverse situation, and it is therefore hardly surprising that the infamous Hays code of the thirties moved to ensure that "the sympathy of the audience shall never be thrown to the side of crime, wrongdoing, evil or sin(4)." The assumption of audience identity with the hero was never unproblematic, and of course the classical Hollywood model of filmmaking partially outlined above never existed entirely without challenge. Nevertheless, it is clear that up to the fifties the classical Hollywood model was relatively applicable and that challenges to it were largely ineffective. However, beyond the fifties, the model became increasingly irrelevant. The reasons for the downfall of the classical paradigm are complex, and related to economic changes within the industry (the forced dismantling of the vertically integrated studio system that placed production, distribution and exhibition roles under the one organisation) as well as wider cultural shifts that occurred during the sixties (the widespread social upheaval and increasing prominence of counter-cultural challenges ... ...he coffee shop scene around the body of the film isolates one couple at the exact moment they make the wrong choice. The cleverness of Tarantino's approach is in isolating the artificiality of his heroes' persona, and using that as an approach with which to undermine the audience's admiration of that hero. Just as Coppola's attempts to alienate the viewer from Michael Corleone were only partially successful, so Tarantino's approach is flawed: Tarantino was accused of glorifying his criminal heroes, and audiences do still see Vincent Vega as a modern day Fonze, the embodiment of coolness. A subtext is still, after all, a subtext, and not everybody can be in the ironic audience. Perhaps, though, the real reason that both Coppola and Tarantino still have problems in avoiding the audience identification with their heroes is the astonishing persuasiveness of classical Hollywood forms. The learned patterns of classical Hollywood narratives and the associated identification with a strong central protagonist are likely to take over if given even the slightest chance. This is the price Coppola and Tarantino must pay if they wish to harness this form of filmmaking for commercial advantage.

Boeing 7 Essay

A reverse of this trend is crucial to reach some of the projected sales numbers that Boeing is counting on. There are several factors to these lower numbers. A decrease in business travel has occurred due to cost and the advance of conferencing technologies. And lastly, the weak economy has vacationers thinking of local destinations instead of traveling abroad. Market Share Boeing’s fiercest competitor is Airbus. It is crucial that the new 7E7 delivers on its promise of lower operating cost. This will help command a larger share of the market. This becomes even more important if the economy doesn’t recover as quickly as we hope. The other aspect of the 7E7’s success is the engineering of an expandable wing. Adding this versatility will give the 7E7 owner more options for travel routes. Sensitivity Analysis The following is the sensitivity analysis of the Boeing project which gives optimistic and pessimistic estimates for the underlying variables of volume and cost of sales. The purpose of the sensitivity analysis is to express cash flows in terms of the variables of this project. Boeing had to determine what the decide what the underlying variables were which in this case happen to be development costs and the per-copy costs to build the 7E7. For the project to increase shareholder wealth, Boeing would have to sell at least 2,500 aircraft over a 20-year period. Airbus is a close competitor. They will be coming to market with a new A380. If Boeing falls behind regarding innovation, they may lose their market share. For Boeing to have a future in the aviation industry, they must take the risk to develop this new place. With the economy so volatile, airlines will be looking for options that reduce their operational costs. The 7E7 will do this. The success of the expandable wing will give the plane attractive versatility. Fuel prices are also on the rise, this is yet another reason why a plane with a lower operating cost will succeed in the future The equity market risk premium should equal the excess return expected by investors on the market portfolio. In this case it was calculated to be 7. 14%. The weighted average cost of capital (WACC) was calculated to be 15. 443%. For the project to increase shareholder wealth, the IRR of the project should at least equal the WACC. For this to happen Boeing would have to sell at least 2500 airliners in a 20-year period.
