Although the history of Virtual Reality (VR) is only about half a century old, all kinds of technologies in the VR field are developing rapidly. VR is a computer generated simulation that replaces or augments the real world by various media. In a VR environment, participants have a perception of “presence”, which can be described by the sense of immersion and intuitive interaction. One of the major VR applications is in the field of sports, in which a life-like sports environment is simulated, and the body actions of players can be tracked and represented by using VR tracking and visualisation technology. In the entertainment field, exergaming that merges video game with physical exercise activities by employing tracking or even 3D display technology can be considered as a small scale VR. For the research presented in this thesis, a novel realistic real-time table tennis game combining immersive, interactive and competitive features is developed. The implemented system integrates the InterSense tracking system, SwissRanger 3D camera and a three-wall rear projection stereoscopic screen. The Intersense tracking system is based on ultrasonic and inertia sensing techniques which provide fast and accurate 6-DOF (i.e. six degrees of freedom) tracking information of four trackers. Two trackers are placed on the two players’ heads to provide the players’ viewing positions. The other two trackers are held by players as the racquets. The SwissRanger 3D camera is mounted on top of the screen to capture the player’s

Since the 1980s, Taiwan has been subjected to heavy foreign and global influences, leading to a marked erosion of its traditional cultural forms. Indigenous traditions have had to struggle to hold their own and to strike out into new territory, adopt or adapt to Western models. For most theatres in Taiwan, Shakespeare has inevitably served as a model to be imitated and a touchstone of quality. Such Taiwanese Shakespeare performances prove to be much more than merely a combination of Shakespeare and Taiwan, constituting a new fusion which shows Taiwan as hospitable to foreign influences and unafraid to modify them for its own purposes. Nonetheless, Shakespeare performances in contemporary Taiwan are not only a demonstration of hybridity of Westernisation but also Sinification influences. Since the 1945 Kuomintang (Chinese Nationalist Party, or KMT) takeover of Taiwan, the KMT’s one-party state has established Chinese identity over a Taiwan identity by imposing cultural assimilation through such practices as the Mandarin-only policy during the Chinese Cultural Renaissance in Taiwan. Both Taiwan and Mainland China are on the margin of a “metropolitan bank of Shakespeare knowledge” (Orkin, 2005, p. 1), but it is this negotiation of identity that makes the Taiwanese interpretation of Shakespeare much different from that of a Mainlanders’ approach, while they share certain commonalities that inextricably link them. This study thus examines the interrelation between Taiwan and Mainland China operatic cultural forms and how negotiation of their different identities constitutes a singular different Taiwanese Shakespeare from Chinese Shakespeare. In recognising this, the core of this thesis rests on how Shakespeare plays speak insightfully to Taiwan society across historical, geographical, and cultural boundaries. Many Shakespeare plays powerfully echo the political turmoil of contemporary Taiwan society, but it is the negotiation of the political and cultural dependency that constitutes a distinct Taiwanese Shakespeare identity that is different from Chinese Shakespeare. This study therefore focuses on Shakespeare performances in contemporary Taiwan between 1986 and 2003, emphasising political context as key factor in adaptation, as Taiwan society transited from a military age to post-millennium democracy after martial law was lifted in 1987.

Additionally, to evaluate stress and excessive daytime sleepiness in ATCO, identifying the impact of these variables on attention activity. Methods: Fifty-two ATCO participated, based at 3 air traffic control units (A, B and C). Sample selection adopted a non-probabilistic convenience approach with sequential selection. Results are presented as descriptive statistics using absolute and relative distribution (n-%), as well as by measures of central tendency and variability, with the distribution of data evaluated using the Shapiro?Wilk test. Pearson's chi-squared (?2) or Fisher's exact test was used to compare between qualitative variables. The Mann-Whitney or Student t test was applied for comparison of continuous variables between two independent groups, and One-way Analysis of Variance with post-hoc Tukey for comparison between three or more groups. Instruments: Wisconsin Card Sorting Test (WCST), Diffuse Attention Test -TEDIF-III, Focused Attention Test -TECON-III, Letter-Number Sequencing -WAIS III, Digit Span -WAIS III, Matrix Reasoning -WAIS III, Lipp Inventory of Stress Symptoms for Adults (ISSL-Lipp), Epworth Sleepiness Scale (ESS) and Questionnaire applied to the ATCO. Results: The ATCO presented mean scores above the population mean for assessment of cognitive flexibility, strategic planning and ability to generate solutions, especially among the group of controllers with 0-5 years of service, whose scores were statistically significant. Considering the Digits, Letter-Number Sequencing and Matrix Reasoning subsets, the ATCO presented weighted scores above the mean, indicating efficient performance in working memory, visual information processing and abstract reasoning. The classification of average and below average prevailed in the focused attention evaluation, with these rates being within the population mean. In the diffuse attention test, they presented an increasing growth between the mean number of correct responses and time of task performance, implying an ability to maintain complex diffuse attention, efficient control of interferences and absence of impairment due to time pressure. Only 16% of the ATCO presented stress symptomatology, with a predominance of physical symptoms (62%). In the evaluation of excessive daytime sleepiness (EDS), statistical significance was identified between sleep and place of work. The ATCO with positive EDS scores worked rotating shifts that included the nighttime period. Conclusion: The executive functioning of ATCO is not influenced by shift work, technical qualification or length of service. Executive functioning is associated with the successful performance of key cognitive resources, such as memory, attention abstract reasoning, planning and flexibility to change. / Objetivo: Avaliar fun??es executivas dos Controladores de Tr?fego A?reo (CTA) relacionando-as com caracter?sticas da atividade profissional, como tempo de servi?o, habilita??o t?cnica e turnos de trabalho.

Pesquisa do Estado da Bahia - FAPEB / This present work represents a study of work of Lygia Fagundes Telles, with the objective of analyzing the tragic presence in her narrative. To achieve this goal were used books of short stories, novels, interviews of the authoress, academic works and books about her work among them studies: Lucas (1990), R?gis (1998), Silva (2001), Rufino(2007), Lucena(2008), Machado(2009) e Gomes(2011).They are analyzed the tales ?Venha ver o p?r do sol?, ?Uma branca sombra p?lida, ?Semin?rio dos ratos?, ?Nada de novo na frente occidental?, and the novel Ciranda de Pedra (1954),investigating the complex interpersonal relationships that the characters feed and how the tragedy unleashes in their lives. We analyzed in what way the tragic is conceived in the narratives, many times from the perspective of classical tragedy, as arising from an individual failure or as the modern conception of the tragic it is inherent in human life. To support the analyzes were used studies about the tragic of the authors Arist?teles (1966), Georg Luk?cs (S/D), Emil Staiger (1977), Junito Souza Brand?o (1985), Rymond Williams (2002), Adilson dos Santos (2005), Friedrich Nietzsche (2007), Albin Lesky (2010) and Vernant and Vidal-Naquet (2014). / O presente trabalho representa um estudo da obra de Lygia Fagundes Telles, com o objetivo de analisar a presen?a do tr?gico em sua narrativa. Para alcan?ar tal objetivo foram utilizados livros de contos, romances, entrevistas da autora, trabalhos acad?micos e livros sobre sua obra, dentre os quais estudos de: Lucas (1990), R?gis (1998), Silva (2001), Rufino (2007), Lucena (2008), Machado (2009) e Gomes (2011). S?o analisados os contos ?Venha ver o p?r do sol?, ?Uma branca sombra p?lida?, ?Semin?rio dos ratos?, ?Nada de novo na frente ocidental?, e o romance ?Ciranda de Pedra? (1954), investigando as complexas rela??es interpessoais que as personagens alimentam e de que forma o tr?gico se desencadeia em suas vidas. Analisamos de que forma o tr?gico ? concebido nas narrativas, muitas vezes sob a perspectiva da trag?dia cl?ssica, como decorrente de uma falha do indiv?duo ou como a concep??o moderna de que o tr?gico ? inerente ? vida humana. Para subsidiar as an?lises foram utilizados estudos sobre o tr?gico dos autores: Arist?teles (1966), Georg Luk?cs (S/D), Emil Staiger (1977), Junito Souza Brand?o (1985), Rymond Williams (2002), Adilson dos Santos (2005), Friedrich Nietzsche (2007), Albin Lesky (2010) e Vernant e Vidal-Naquet (2014).

We sought to further identify the influence of the variables gender, age and schooling. 319 participants (117 from the group of non-offenders, 135 from the group of non offenders and 109 involved in accidents), with ages ranging from 17 to 77 years (M=40.62, SD=10.8) with varied educational (Elementary Education, Secondary Education and Higher Education) of both sexes (314 men and 47 women) responded to the tests R1, Aten??o Concentrada and Palogr?fico, during the evaluation process for transit. The means and standard deviations for each subgroup were calculated and compared by analysis of variance. The results showed that the variable group did not affect any of the measures, only your interaction with sex in the measure of productivity in Palogr?fico (F = 4.18, p ? 0.001). There was also the influence of age on performance on the test R1 (F = 6.55, p ? 0.001), as well as its interaction with the group in the number of hits in the test AC (F = 1.85, p ? 0.001). Given some limitations of the study, such as uneven number of participants by sex and the use of a questionable criterion for separation of groups (self-report in relation to accidents and transit s fine), further studies are recommended to ensure that confirm or not the results. / Considerando a import?ncia de pesquisas que visam avaliar a efic?cia dos instrumentos que v?m sendo utilizados para avalia??o psicol?gica no contexto do tr?nsito, o presente trabalho teve por objetivo identificar a validade das medidas que vem sendo utilizadas, por meio da an?lise do desempenho de diferentes grupos de motoristas (motoristas infratores, n?o infratores e envolvidos em acidentes) quanto aos construtos de intelig?ncia, aten??o concentrada e personalidade. Buscou-se ainda identificar a influ?ncia das vari?veis g?nero, escolaridade e faixa et?ria no desempenho dos participantes. Nesse sentido, 319 participantes (117 do grupo dos n?o infratores, 135 do grupo dos infratores e 109 dos envolvidos em acidentes), com idades variando entre 17 a 77 anos (M=40,62, DP= 10,8) com escolaridade variada (Ensino Fundamental, Ensino M?dio e Ensino Superior) de ambos os sexos (314 homens e 47 mulheres), responderam aos testes R1, Aten??o Concentrada e Palogr?fico durante processo de avalia??o pericial para o tr?nsito. As m?dias e desvios padr?o para cada subgrupo foram calculadas e comparadas por meio da An?lise de Vari?ncia. Os resultados demonstraram que a vari?vel grupo n?o exerceu influ?ncia significativa em nenhuma das medidas, somente sua intera??o com sexo na medida de produtividade do teste Palogr?fico (F=4,18, p? 0,001). Tamb?m foi encontrada influ?ncia da faixa et?ria no desempenho no teste R1 (F=6,55, p? 0,001), assim como sua intera??o com a vari?vel grupo no n?mero de acertos no teste AC (F=1,85, p? 0,001). Dadas algumas limita??es do estudo, tais como desigual n?mero de participantes por sexo e o emprego de um crit?rio question?vel para separa??o dos grupos (auto-relato em rela??o ? multas e acidentes), novos estudos s?o recomendados a fim de que os mesmos confirmem ou n?o os resultados encontrados.

For circuit switched voice networks dimensioning, the Erlang formulas are used. When it comes to newer data networks, a packet based dimensioning is required, and the complexity is significantly increased due to the diversity of applications and its multiple features. This work goes from the mathematical model (proposed by Erlang) applied to circuit switched voice networks to a mathematical model applicable to data services and packet based network dimensioning. User and application requirements are detailed as well as the correlation between them, which is key to understanding the dimensioning model. The mathematical model is applied (and a study case is presented) to an existing 3G technology (1xEVDO) in Brazil using practical input values. A computer program is generated to run prompt tests or different study cases. Then, the obtained results for the given case are measured in the field to validate the packet based network dimensioning model. Computer simulations are run to test the edge of the 1xEVDO technology with the aid of appropriate software containing queuing theory concepts. The experiments permit the correct visualization of the possible values that can be obtained and should be ignored on the dimensioning of a packet based network. Although ITU s 1xEVDO technology is used for the experiments, the dimensioning model is proposed to be applicable to any technology which needs packet based dimensioning and has data applications (i.e. other ITU 3G technologies such as UMTS and IEEE technologies such as wifi e wimax). The model is constructed, applied to study cases, tested on the field with practical values, promptly validated and pushed to the edge during simulations. / Pesquisa sobre os modelos de dimensionamento de rede de voz e de dados aplicados nas redes de telecomunica??es. Para a aplica??o de voz, as redes s?o dimensionadas a circuito, realiza-se um resgate do dimensionamento desse servi?o utilizando-se as f?rmulas de Erlang. Destaca-se, em seguida, que as novas redes de dados requerem um dimensionamento baseado a pacotes e a complexidade aumenta significativamente devido a diversidade das aplica??es e de suas m?ltiplas caracter?sticas. Evolui-se, do modelo matem?tico proposto por Erlang, aplic?vel ?s redes de voz baseado em circuito, at? um modelo matem?tico aplic?vel aos servi?os de dados a ser utilizado no dimensionamento das redes a pacotes. Detalham-se os requisitos dos usu?rios e das aplica??es, bem como a correla??o entre eles, que ? a chave para o entendimento do modelo de dimensionamento. Aplica-se o modelo matem?tico (gera-se um case) para a tecnologia 3G existente em opera??o no Brasil no momento, 1xEVDO com valores de entrada utiliz?veis na pr?tica. Gera-se um programa para ensaios pontuais ou diferentes cases. Medem-se em campo os resultados obtidos do case utilizado para valida??o do modelo de dimensionamento de rede a pacotes. Para os extremos da tecnologia, 1xEVDO, s?o ensaiados com a utiliza??o de um simulador de um software aderente e alinhado a teoria das filas. Promovem-se ensaios que permitem a vis?o correta dos valores poss?veis de serem obtidos e que devem ser ignorados no dimensionamento de uma rede a pacotes. Destaca-se que, apesar de se haver utilizado a tecnologia 1xEVDO do ITU para ensaio, o modelo de dimensionamento ? proposto a ser aplicado em qualquer tecnologia que necessite de dimensionamento baseado em pacotes e com aplica??es de dados (demais da terceira gera??o do ITU como UMTS e do IEEE como wifi e wimax). O modelo ? conceituado, aplicado em case, testado em campo com valores pr?ticos, convalidado pontualmente e extremado em simula??o.

The thesis contends that there is a dominant strand of thinking driving the prevailing metanarrative of American global hegemony. This strand, constructed here as Ameritocracy, taps into three interconnected and fundamental principles concerning the nature of America: that American values are universal, terminal and providential. However, this notion of American universality is contradicted by a troubling parochialism, one that reveals religious, racial and cultural particularities generated from American identity, and from the mythic, providential origin story of America. The thesis expands on the theory of Ameritocracy, its historical derivation and theoretical antecedents, and its application within the soft power realm of Hollywood film. Ameritocracy finds its apotheosis in the popular blockbuster films of the unipolar era. The global aspirations of the blockbuster conflate with the universality of the medium, and thereby function as the perfect conduit for expounding the presumed universality of the American nation, promoting and proselytising on behalf of American primacy, using Ameritocratic arguments to legitimise and normalise U.S. hegemony. Analysis of blockbuster texts reveals that the notions of universality they embed are often partial and particular, featuring an obfuscation of definitions, between ideals and interests, between ends and means, and between the universal and the American.

Praticado um fato que tenha contornos de um delito, a san??o s? poder? ser aplicada ao seu autor ao final de um devido processo, com observ?ncia de regras pr?prias.
