Seu uso como objeto de estudo em escolas e universidades tem crescido e atingido diferentes áreas. A charge (do francês charger: carregar, exagerar) tem como objetivo a crítica humorística de um fato específico, geralmente de natureza política. Ela deve abordar um assunto atual e interessante para o público leitor. O objetivo central desse estudo é mostrar a como se organizam os modos de linguagem do texto chárgico, ressaltando que argumentos também podem ser constituídos por linguagem visual. Nosso ponto de partida é uma análise sócio-interacionista, a qual vislumbra o processo comunicativo da charge. Em seqüência, apresentaremos uma proposta de análise multimodal do gênero em estudo para só então realizarmos nossas considerações sobre a argumentação. Para tanto, nosso corpus é composto por aproximadamente 450 charges, as quais foram coletadas nos três principais jornais de Pernambuco Jornal do Commercio, Diario de Pernambuco e Folha de Pernambuco. Este trabalho ocorreu durante os meses de junho a outubro de 2006, período de copa do mundo e de eleições, assuntos que dão uma boa safra de charges

Essas alterações também repercutiram na linguagem, sobretudo com o advento da Internet, e colaboraram para modificar as relações de leitura e escrita. A Charge Virtual, através da Análise Crítica do Discurso e da análise multimodal, é um gênero ideal para investigar a construção de identidades sociais. Esta pesquisa tem por finalidade analisar as Charges Virtuais, especificamente do autor Maurício Ricardo exibidas no site www.charges.com.br e observar como os diversos modos de organização (animação, texto-verbal, áudio e imagem) interagem e formam a significação do gênero em análise. Além disso, este estudo procura investigar, tendo como base a Análise Crítica do Discurso e a análise multimodal, de que maneira as relações lingüístico-discursivas constituem uma base para a construção de identidades por meio de discursos estereotipados presentes nas falas das personagens da charge

La modélisation des effets de l’entraînement sur la performance permet de mieux conceptualiser les adaptations du sportif pour aider les entraîneurs confrontés à de multiples incertitudes, avec comme alternatives possibles à une performance de haut niveau, le surmenage, le surentraînement et la blessure. La quantification quotidienne de la CE est alors la première étape de la périodisation de l’entraînement. Notre revue de la littérature montre que ces effets sont un état non définitif des interactions entre différents facteurs exogènes et endogènes (Banister et coll., 1975, Busso et coll., 1990, Morton et coll., 1990). La notion de charge d’entrainement implique un niveau d’effet se traduisant dans l’organisme sous la forme de réactions fonctionnelles qui ont une certaine intensité et une certaine durée. Cela implique de suivre quotidiennement plusieurs marqueurs perceptifs.Les progrès de l’informatique et des objets communicants nous ont permis de concevoir un système informatique ergonomique afin de récupérer, de traiter, et de visualiser un grand volume de données, mais aussi de proposer une modélisation alternative des effets de l’entraînement. Nous inspirant des mécanismes généraux de régulation de l’homéostasie et de la chronobiologie, nous avons postulé que la capacité de performance quotidienne peut être modélisée par une onde dont l’amplitude, après avoiratteint un maximum, diminue graduellement pour tendre à retourner à son niveau initial durant les jours qui suivent (oscillation harmonique amortie). Nos résultats permettent de discuter des possibilités d’un tel système sur l’analyse des pratiques des entraîneurs en termes de gestion de la charge d’entraînement aux différentes périodes de l’année. Malgré le faible nombre de sujets (six joueuses), ils montrent que l’utilisation du concept d’oscillation harmonique amortie pour modéliser les effets cumulés et différés de l’entraînement semble prometteuse. Mais avant de l’appliquer à de plus vastes types de publics et de pratiques (réathlétisation, suivi de l’activité physique d’un public âgé), de plus amples recherches sont nécessaires / Modelling the training effects on performance allow to better conceptualize athleteadaptations to training to help coaches faced with many uncertainties, as possiblealternatives to high level performance, overreaching, overtraining and injury. The dailytraining load (TL) quantification is then the first step of the training periodization. Ourlitterature review shows that these affects are non final statement of interactions betweenexogenous and endogenous factors (Banister et coll., 1975, Busso et coll., 1990, Morton et coll., 1990). The concept of TL involves an effect level resulting in the body in the form offunctional responses that have a certain intensity and a certain time. It involves followseveral perceptual markers daily.The advances made in the area of computer and communication technologies nowoffer new opportunities for designing an ergonomic computer system to collect, process,and visualize large amounts of data, but also provides an alternative modelling of thetraining effects. Inspired by the general mechanisms regulating homeostasis andchronobiology, we postulated that the performance capacity of each training day can bemodeled by a wave whose amplitude, after reaching a maximum, gradually decrease totend to return to its initial level during the following days (damped harmonic oscillation).Our results allow us to discuss the possibilities of such a system on an analysis ofthe coaches practices in terms of training load management at different times of the plan.Despite the small number of subjects (six players), they show that the use of the concept ofdamped harmonic oscillation model for the cumulative and delayed effects of trainingappears promising. But before applying it to a wide range of subjects and practices(rehabilitation, physical activity of older person), further investagtion is needed

This thesis discusses the pion double charge exchange (DCX) reaction ¹⁸0(π⁺,π⁻)¹⁸Ne at 50 MeV. Transitions to the ground state of ¹⁸Ne, which is the double-isobaric-analogue state (DIAS) of ¹⁸0, have been isolated. The differential cross sections for DIAS transitions have been measured at 6 scattering angles from 18.2° to 122.6°. The experiment was performed at TRIUMF in December 1984 using the QQD low energy pion spectrometer [26]. The differential cross section angular distribution is forward peaked, falling from 4.7±0.5 μb/sr at 0° (by extrapolation) to 0.61±0.11 μb/sr at 122.6°. The total (angle-integrated) cross section is 16.2±1.2 μb. DCX measurements are expected to give information on nuclear structure that is hard to obtain by other reactions. This information includes short range correlations and neutron-proton density differences. However, before such information can be extracted the mechanism for DCX must be understood. The aim of this experiment was to provide more data to test the various theories of the DCX mechanisms. The implications of the results for several theories of DCX are discussed. The forward peaking of DCX angular distributions at 50 MeV was unexpected. 50 MeV single charge exchange (SCX) angular distributions are forward dipped e.g. [14], a result of the cancellation of the 0° s and p wave scattering amplitudes for the reaction p(π⁺,π⁰)n. Early DCX calculations were based on the simple sequential mechanism. This assumes DCX proceeds via 2 successive SCX reactions, with the isobaric analogue as the intermediate state. These calculations predicted forward dipping and small cross sections for DCX [13,15]. The data shows this mechanism is an over-simplification. The standard model for π-nucleus scattering is the optical potential. Johnson and Siciliano are developimg a potential with which to calculate elastic, SCX and DCX cross sections [48,38,22]. They include second, order terms, important in DCX because the reaction must involve scattering by at least two nucleons. By using a general form for the optical potential they include contributions from excited intermediate states. Miller has suggested the forward peaking is due to the presence of six-quark clusters in the nucleus [16]. His model reproduces the data for 50 MeV DCX on ¹⁸0 and ¹⁴C at forward angles. Karapiperis and Kobayashi have used the Δ-hole model to calculate elastic, SCX and DCX cross sections [19]. They obtain fair agreement with data for a range of nuclei and energies. Jennings et al. [22] are developing a model in which short range correlations produce the forward peaking. This work is at an early stage. More DCX measurements are needed to choose between the various models. Measurements at 50 MeV are particularly valuable because the simple sequential mechanism is small, allowing other mechanisms to be observed. Further data such as excitation functions below 80 MeV and angular distributions for other nuclei are needed. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

The current study aimed to examine attitudes of sexuality of individuals with CHARGE syndrome by exploring potential barriers that may exist due to differences in the attitudes towards sexuality in parents of individuals with CHARGE syndrome and those attitudes of adults with CHARGE syndrome. Participants included 24 adults with CHARGE syndrome and 31 parents of individuals with CHARGE syndrome. The Attitudes of Sexuality-Individuals with Intellectual Disabilities (ASQ-ID) was completed by all participants and was adapted to address this specific population for the current study. Using a multivariate analysis of variance (MANOVA), four themes of sexuality from the ASQ-ID (i.e., sexual rights, parenting, non-reproductive sexual behavior, and self-control) were examined by comparing differences of mean scores across parents of individuals with CHARGE syndrome and adults with CHARGE syndrome. Further, standard linear regressions were used to determine if age was a predictor of attitudes of sexuality within this population. Results indicated that while there was not a statistically significant difference between parents’ overall scores and adults with CHARGE syndrome’s overall score, statistically significant differences were found in two of the subscales. Specifically, adults with CHARGE syndrome were found to have more positive views in the area of parenting, as compared to parents of individuals with CHARGE syndrome. Likewise, parents of individuals with CHARGE syndrome were found to have more positive views in the area of self-control, opposed to adults with CHARGE syndrome. Further, age was not found to be a predictor of attitudes of sexuality within this population. The results and implications of the findings are discussed, as well as limitations and future directions.

Este trabalho apresenta dois problemas distintos. No primeiro, obteve-se a característica da corrente em função da voltagem em um dielétrico sob radiação, supondo-se que só um portador seja móvel, que recombinação e injeção da carga móvel através de um eletrodo. Na interface eletrodo-dielétrico foi imposta a condição de densidade de carga constante. No outro problema foi feita uma generalização do problema transiente clássico estudado por Many e Rakavy, usando a mesma condição anterior de densidade de carga constante no eletrodo injetor. Obteve-se soluções analíticas durante o 1º tempo de trânsito e de desenvolveu soluções por computador até o 3º tempo de trânsito. As oscilações amortecidas da corrente em torno do valor estacionário, também merece alguma atenção / Two distinct problems are treated here. In the first one, the relation between current and voltage in a dielectric under radiation is obtained, assuming only carrier to be mobile, recombination and injection of the mobile charge from the electrode. We have chosen for this last boundary condition a constant charge density at the electrode-dielectric interface. The second problem treated is a generalization of the classic transcient problem studied by Many-Rakavy, using the constant charge density boundary condition. Analytic solutions were obtained during the first transit time and computed ones for larger times. Some attention was given to the damped current oscillations approaching the steady state value
