Full textAbstract:
La spectrométrie de masse, en particulier le couplage HPLC/MRM3, est un outil bien adapté au diagnostic in vitro, particulièrement en microbiologie clinique. L'utilisation en routine de cette technologie est cependant tributaire de sa sensibilité et de sa spécificité. Ce travail de thèse a pour objectif d'étudier la possibilité d'éjecter et de détecter simultanément et de façon sélective des ions de ratio masse/charge donnés, ceux-ci étant confinés dans un piège ionique quadrupolaire. Cette approche permet de supprimer les étapes de balayage en masse et d'intégration mathématique du signal en mode MRM3 ce qui permet de gagner à la fois en sensibilité et en spécificité (en diminuant le temps de cycle et en diminuant le rapport signal sur bruit). Cet objectif a été poursuivi premièrement par une étude théorique approfondie des équations du mouvement des ions dans un piège radiofréquence ; deuxièmement par une étude numérique de la stabilité de ces équations et enfin troisièmement par une validation expérimentale de ces résultats théoriques. La présentation de ces trois approches fait l'objet du présent mémoire

Les modulateurs electro-optiques (EOM) sont des composants importants dans les systemes de telecommunication. Malheureusement, ils ne sont pas parfaitement stables dans Ie temps et leur fonction de transfert (TF) a tendance a se decaler durant Ie temps d'operation. La derive de la TF d'un EOM peut etre expliquee par des effets differents tels que les changements de la temperature ambiante, de la polarisation ou de l'efficacite de couplage optique. La these presente une methode de me sure de la derive de la TF de I'EOM (a grace d'estimation du comportement non-linearite du modulateur, NLl), et propose deux systemes instrumentaux pour ameliorer son fonctionnement: Ie premier pour contraler la temperature de l'EOM, il est possible de forcement reduire cette derive, Ie deuxieme pour compenser la derive (la stabilisation du point de fonctionnement autour du point quadrature est obtenue jusqu'au 0,22% ou la fluctuation de phase est de 0,44°). Ces techniques ont ete aussi appliquees pour ameliorer Ie comportement d'un oscillateur optoelectronique haute frequence. Nous avons realise les experiences par asservissement de temperature, par compensation de la derive. Pour une stabilite de I'OEO a court terme, la stabilisation de la frequence est amelioree jusqu'a 28% en utilisant un contrale de temperature seule etjusqu'a 71 % avec les deux processus. Pour une stabilite de l'OEO a long terme, en deux cas sans contra Ie, I'OEO fonctionne pendant 3 heures et pendant 1,6 heure (puis I'OEO ne marche plus). En utilisant une compensation de la derive de la TF de I'EOM, l'OEO fonctionne bien meme apres 7 heures et 8 heures.

This research is compiled and organized inside a database articulated to the thesis throughout the argument. The description of this documentary corpus and the creation of this specific tool are given in the first part of this dissertation. A second part, devoted to the study of physical characteristics of these instruments, aims to provide an objective discourse on the nature of the instrument and its components: forms, strings, pins, holding manners, playing modes, etc. This part ends with an instrumental reconstitution exercise. A third part examines the social image and symbolic image of the instruments trying to encompass all speech – both literary and visual – related to the board zithers around the medieval notion of translatio, which will be in this particular case called translatio musicae. This work will conclude with a proposition of a specific organological classification for medieval board zithers, which might possibly be adapted to the study of other musical instruments

Full textAbstract:
Introdução: Na Doença de Alzheimer, o comprometimento no desempenho nas Atividades de Vida Diária (AVD) impacta diretamente a autonomia e independência do indivíduo. A capacidade funcional determina o nível de auxílio que uma pessoa irá necessitar no cotidiano para uma vida em segurança e com autonomia. Dentre os domínios cognitivos, a Função Executiva tem sido relatada como a mais associada com o desempenho de funcionalidade. Há a necessidade de instrumentos válidos para avaliar os déficits das funções executivas no desempenho de tarefas de mundo real em pacientes com doença de Alzheimer (DA) no Brasil. Objetivo: Validar a versão brasileira do teste Executive Performance Test (EFPT) em pacientes com doença de Alzheimer (DA). Métodos: Adaptação cultural do EFPT para o português do Brasil. Os estudos de confiabilidade e validade foram realizados com três grupos de idosos: controles, DA leve e DA moderada. Este estudo examinou a estabilidade do instrumento, a consistência interna (alfa de Cronbach), a validade de constructo e de critério e análises de precisão. Resultados: A amostra foi composta de 83 participantes com 60 anos ou mais, distribuídos em três grupos: controle, DA leve e DA moderada. A confiabilidade inter examinadores foi alta (ICC = 0,985), com alta consistência interna (Cronbach ? = 0,967). Houve forte correlação entre EFPT-Br Total e DAFS-BR (r = -0.762), correlação fraca a moderada com a bateria cognitiva e correlação moderada a forte com a bateria funcional. Foi realizado o cálculo da da ROC multiclasse área sob a curva de 0,8933, a pontuação sugerida para diferenciar os grupos : menor que 8 para controles; entre 9 e 27 para DA leve; e acima de 28 para DA moderada, para discriminar grupos. Conclusão: O EFPT-BR é um teste válido, com parâmetros psicométricos satisfatórios, para discriminar pacientes saudáveis, com DA leve e DA moderada na realização de tarefas instrumentais. O teste fornece informações consistentes para auxiliar a compreensão do desempenho de pacientes com DA na realização de atividades de vida diária com mais autonomia e segurançaBackground: In Alzheimer\'s disease, the impairment in performing Activities of Daily Life (ADL) directly affects the autonomy and independence of the individual. The functionality determine a person needs for a safe and autonomous life. Among the cognitive domains, Executive Function has been reported as the most associated with functionality performance. There is a need for valid assessments to evaluate the deficits of executive functions in performing of real world tasks with patients with Alzheimer\'s disease (AD) in Brazil. Objective: To validate to Brazilian Portuguese version of the Executive Function Performance Test (EFPT) in Alzheimer disease (AD) patients. Methods: Cultural adaptation of EFPT to Brazilian Portuguese. The reliability and validity studies were performed with three groups of elderly: controls, mild AD and moderate AD. This study examines instrument stability, an internal consistency (Cronbach\'s alpha), a construct and criterion validity, and precision analyzes. Results: The sample consisted of 83 participants aged 60 years and over, divided into three groups: control, mild AD and moderate AD. The inter-examiner reliability was high (ICC = 0.985), with high internal consistency (Cronbach ? = 0.967). There was a strong correlation between EFPT-Br Total and DAFS-BR (r = -0.762), weak to moderate correlation with a cognitive battery and moderate to strong correlation with the functional battery. We performed the calculation of the ROC multiclass area under the curve of 0.8933, a score suggested to differentiate the groups: less than 8 for controls; between 9 and 27 for mild AD; and above 28 for moderate AD, to discriminate groups. Conclusion: EFPT-BR is a valid test with satisfactory psychometric parameters to discriminate healthy patients with mild AD and moderate AD in performing instrumental tasks. The test provides consistent information to assist in understanding the performance of AD patients in carrying out more autonomous and safe daily life activities

Research has demonstrated that everyday functional abilities are compromised in mild cognitive impairment (MCI), a transitional stage between normal cognitive aging and dementia, as well as in healthy aging. These functional changes have been shown to be strong predictors of future decline, highlighting their importance. However, early changes in everyday functioning remain poorly characterized, largely due to a scarcity of sensitive measures capable of detecting subtle disruption. Recent research suggests that eye-tracking methodology may be effective in addressing this gap. Fifty-two participants (27 younger adults and 25 non-demented older adults) completed a novel eye-tracking task involving passive viewing of a naturalistic scene and verbalization of a task goal (e.g., make coffee, pack a lunch). Participants also completed a performance-based measure of everyday action that required them to enact the same tasks (e.g., coffee, lunch) that were included in the eye-tracking paradigm, self-report measures of functional ability, and neuropsychological measures. Mixed ANOVAs were conducted to examine group (young, old) and condition (passive viewing, verbalization)/task (simple, complex) effects on eye-tracking and everyday action performance. Independent samples t-tests/Mann-Whitney U tests were conducted to examine group differences in eye-tracking and everyday action performance. Correlation analyses across all measures were conducted to evaluate the potential mechanisms of eye-tracking and everyday action results. Results showed no significant group differences in the primary eye-tracking variables, but both groups made a lower proportion of fixations to distractor (i.e., non-target) objects during task verbalization compared to passive scene viewing. Older adults made more inefficient actions during performance-based everyday task completion, particularly when task demands were high. Eye tracking and everyday action variables were related to different measures of self-reported functional ability. Finally, eye-tracking variables were primarily related to neuropsychological measures of executive functions/working memory, whereas everyday action performance was most strongly related to measures of verbal learning and memory. These findings suggest that age-related functional changes at the level of eye movements may occur after changes in behavioral performance of everyday tasks. Importantly, performance-based assessment of everyday action appears sensitive to age-related decline. Additionally, naturalistic eye movements and everyday task performance may reflect distinct components of self-reported functioning and may be driven by distinct cognitive processes. Future research with refined naturalistic eye-tracking tasks and samples with a wider range of impairment is necessary to further explore these findings and improve characterization and detection of risk for dementia.

Full textAbstract:
Despite being ubiquitous within the Classical style, pedals have received little attention in the scholarly literature. This dissertation adopts a form-functional approach to understanding them with an eye toward distinguishing their normative and non-normative functions. A form-functional approach begins by parsing the musical surface into formal and temporal functions. William Caplin has identified five distinct temporal functions: 1) “before-the-beginning”; 2) “the beginning”; 3) “the middle”; 4) “the end”; and 5) “after-the-end.” Appearing mostly in locations 2) and 5), tonic pedals express two primary functions, formal initiation and postcadential closing for a theme. Dominant pedals also express postcadential function, but close less stable areas like transitions. They also appear in location 3), most notably in contrasting middles, where they bring harmonic contrast or uncertainty and anticipate a recapitulation. Because they frequently mediate between the home and subordinate key, I have devised four categories of dominant pedal that bring a sense of clarity to the range of functions dominant pedals can serve. Vd → Vd pedals normally express a postcadential standing-on-the-dominant or a contrasting-middle function. Vt → Vt pedals express the same functions, but in a more stable way. Vt → Vd pedals express a retransition function or a contrasting-middle function that enacts a harmonic transformation. The Vd → Vt pedal also expresses a contrasting-middle function, but reverses the direction of the harmonic transformation. Finally, with regard to their non-normative functions, pedals can loosen their formal contexts by generating form-functional overlap and expansion.

Full textAbstract:
Most of us can recall chuckling, or even laughing out loud, at a humorous musical passage and perhaps recalling how much that experience increased our enjoyment of the music. This study focuses on humour in the instrumental works of Haydn, Mozart, and Beethoven: composers who have been singled out by contemporary and modern scholars for their ingenuity and mastery of the Classical style. In the most general sense, musical humour arises when composers play with established conventions of musical discourse by writing something incongruous according to the stylistic context. Chapter 1 demonstrates how historical critics understood the role of contrast in examples of musical humour and wit. It then surveys many recent music-theoretical discussions of musical humour, before briefly introducing how elements of contrast, “valence shifts,” and “opposition” are involved in musical humour from the Classical period. This study’s analytical and theoretical approach to musical humour draws on recent studies of musical humour, form, and communication in the Classical style, as well as concepts from recent linguistic theories of humour. Chapter 2 introduces the two primary strategies Classical instrumental composers employed to create musical humour: “opposition” and “excess.” Chapters 3 and 4 discuss a wide range of musical examples to explore how composers deployed formal functions and musical topics to produce humour. These discussions provide a sense of the wide range of effects that fall under the umbrellas of opposition and excess. Chapter 5 concludes by briefly examining some performance applications of this study and suggesting some further potential sources of musical humour.Arts, Faculty of

O Programa de Enriquecimento Instrumental (PEI) é um programa psicoeducativo que busca, por meio de instrumentos apropriados, estimular funções cognitivas de forma que o aluno otimize seu pensamento e torne-o mais reflexivo. O objetivo desta pesquisa foi realizar uma avaliação da influência do Programa de Enriquecimento Instrumental sobre algumas funções cognitivas dos idosos, quais sejam: resolução de problemas, memória, atenção e concentração. Participaram 66 indivíduos voluntários de ambos os sexos, com idade igual ou superior a 60 anos, fisicamente independentes e saudáveis, com escolaridade mínima 4ª série do ensino fundamental I (atual 5º ano) e máxima 8ª série do ensino fundamental II (atual 9º ano), sem restrições quanto ao nível socioeconômico, subdivididos em dois grupos: experimental e controle. Os sujeitos de ambos os grupos foram avaliados antes do início do programa de intervenção (fase pré-teste) e ao seu final (fase pós-teste) por meio dos seguintes testes: Teste Wisconsin de classificação de cartas versão para idosos, subescala memória do Exame Cognitivo de Addenbrooke, Teste de Memória de Lista de Palavras, Teste de Repetição de Pseudoplavaras, subescala atenção e orientação do Exame Cognitivo de Addenbrooke e teste de Trilhas parte A e parte B. Com o objetivo de rejeitar a hipótese de que a melhora do desempenho do grupo experimental, que recebeu a intervenção cognitiva, pudesse ser devida a aprendizagem dos testes na primeira fase em que foram aplicados, outros testes para avaliação das mesmas funções investigadas foram realizados nas fases pós e reteste, esta última realizada após três meses do término do programa de intervenção. Os testes com este objetivo foram: subteste cubos da Escala Wechsler Abreviada de Inteligência, testes de extensão de dígitos em ordem direta e em ordem inversa da Escala de Memória Wechsler de Inteligência para Adultos, Bateria Psicológica para Avaliação da Atenção. A escala de autoestima foi aplicada nas fases pré, pós e reteste apenas para o grupo experimental. As aulas do Programa de Enriquecimento Instrumental foram ministradas ao grupo experimental pela pesquisadora durante cinco meses e meio, uma vez por semana com a duração de 90 minutos cada, totalizando 21 aulas. A avaliação dos resultados mostrou que o Programa de Enriquecimento Instrumental levou a um maior desempenho do grupo experimental quando comparado ao grupo controle em todas as funções cognitivas analisadas, as quais ou se mantiveram ou apresentaram melhoras no desempenho mesmo após três meses do término do programa. Na discussão dos resultados procurou-se identificar e relacionar os instrumentos do PEI com as funções cognitivas avaliadasThe Instrumental Enrichment Program (IEP) is a psycho-educative program that seeks, through appropriate instruments, to stimulate cognitive functions so the student optimizes her/his thinking and makes it more reflective. The objective of this research was to conduct an assessment of the Instrumental Enrichment Program influence on some cognitive functions of the elderly, such as: problem solving, memory, attention and concentration. Sixty-six volunteers from both sexes participated, aged 60 years or older, physically independent and healthy, schooled until the 4th grade of elementary school (currently 5th year) at minimum and until the 8th grade of secondary school (currently 9th year) at maximum, without restrictions on the socioeconomic level, subdivided into two groups: experimental and control. The subjects from both groups were assessed before the intervention program (pre-test phase) and its ending (post-test phase) through the following tests: Wisconsin Card Sorting Test version for the elderly, memory subscale of Addenbrookes Cognitive Examination, Word List Memory Test, Pseudowords Repetition Test, attention and guidance subscale of Addenbrooke\'s Cognitive Examination, and Trails Test parts A and B. In order to reject the hypothesis that improvement in the experimental group performance, that received cognitive intervention, could be due to the learning of tests during the first phase in which they have been applied, other tests for evaluation of the same investigated functions were performed in post-test and retest phases, the latter performed after three months of the intervention program completion. The tests used for this purpose were: Wechslers Abbreviated Scale of Intelligence cubes subtest, digit extension tests in direct and in reverse order from Wechslers Adult Intelligence Memory Scale, and Psychological Battery for Attention Assessment. The self-esteem scale was applied in the pre, post and retest phases only for the experimental group. The Instrumental Enrichment Program classes were given to the experimental group by the researcher for five and a half months, once a week, lasting 90 minutes each, totaling 21 classes. Evaluation of the results showed that the Instrumental Enrichment Program has led to a higher performance by the experimental group compared to the control group in all cognitive functions analyzed, which either remained or showed improvement in performance even after three months of program completion. The discussion of results sought to identify and relate the IEP instruments with the assessed cognitive functions

Este trabalho consiste na aplicação de técnicas de identificação de parâmetros estruturais, especificamente massa, rigidez e amortecimento, à caixa acústica de um violão clássico. A abordagem experimental tradicional é adotada, com medição de aceleração em um ponto da estrutura e excitação proveniente de martelo instrumentado registrada em diferentes pontos. As funções de resposta em frequência são então traçadas para, em conjunto com um modelo analítico representativo dos primeiros graus de liberdade do acoplamento ar/estrutura, realizar-se o ajuste de curvas e posterior identificação dinâmica. Para tanto, esta última etapa foi tratada como um problema matemático de otimização não linear no qual se busca a minimização de uma função objetivo que contabiliza de alguma forma a diferença entre o resultado das medições e os valores previstos pelo modelo utilizado. Várias funções de erro (objetivo) e vários algoritmos foram utilizados, como mínimos quadrados não linear, simplex de Nealder-Mead, algoritmo genético padrão e enxame de partículas (particle swarm), entre outros, sendo este último o de melhor desempenho entre todos, quando aplicado em conjunto com a norma da diferença dos logaritmos das magnitudes ao quadrado. Assim, uma calibração com boa concordância entre dados experimentais e resultados teóricos foi estabelecida para o modelo proposto, sendo realizada também a verificação do ajuste através da comparação de um conjunto independente de dados, trazendo, desta forma, confiabilidade para posteriores cálculos das grandezas associadas ao comportamento dinâmico utilizando-se o modelo ajustado.This work aims at identify structural parameters of a classical acoustic guitar’s resonant chamber by comparing theoretical and experimental frequency response functions. The quantities used to construct the mass, stiffness and damping matrices of an air/structure analytical model, which is representative of the first few modes of the body, are considered as project variables, and an impact vibration testing approach is used to obtain the measured data, with a roving instrumented hammer and an accelerometer attached to a predefined point of the body. Then, a curve-fit analysis is performed as a mathematical problem of non-linear optimization, wherein the objective function, which is to be minimized, somehow accounts for the difference between the measured data and the theoretically predicted values. Some different error (objective) functions and optimization algorithms, like non-linear least-squares, Nealder-Mead simplex, standard genetic algorithm and particle swarm, among others, were applied, and the latter yielded, together with the squared error norm, the best performance. Then, an updated model was achieved with fair agreement between analytical predictions and experimental results, verified using a validation data set, bringing reliability for further theoretical predictions.

The focus of this master's thesis is on the topic of instrumentation during the compilation process in the LLVM compiler. The tool enables to instrument memory accesses and functions. The instrumentation is realized through adding a novel pass to the LLVM's optimalization phase. Information about variables are managed by the created framework. The framework is linked with the program. The overhead of the instrumentation increases duration of the program by about 14 % in the case of switched off indirect addressing and 23 % in the case of switched on indirect addressing. The main benefit of the work is the possibility of easy instrumentation of the program which can even monitor operation of local variables through indirect addressing) and support multithread programs. The framework is part of Testos's tools where it provides automatic instrumentation in the Spectra tool.

In this work it is discussed the improvement in the modal test for obtaining the Frequency Response Function (FRF) in low natural frequency structures by using as exciter an instrumented hammer. There are two conflicting needs in this kind of test: on the one hand, the low natural frequencies of the structure, which are usually associated with low damping, demand long acquisition time so that good resolution in the spectrum may exist. On the other hand, the sampling rate must be increased to correctly catch the short duration signal of the hammer. This leads to an elevated number of points in the signal to be acquired, and there may eventually be limitation on such number of points when using spectrum analyzers in the acquisition and obtaining of the FRFs. Thus, in this work, the selective decimation technique explored for the improvement of the test. The work includes the construction of a prototype with two degrees of freedom (S2GL) to serve as case study for the tests enabling the theoretical and experimental Frequency Response Functions (FRF) to be compared, as well as adjusting the parameters of the model. The MATLAB programming language was used for obtaining the FRFs. The efficiency of the improvement applied was verified through the frequency spectra, in which it was observed significant resemblance between the non-decimated FRF with the acquisition having a high number of points, and the decimated FRF with smaller number of points and selected so that it could preserve the correct detection of the hammer signal.
Neste trabalho discute-se o aprimoramento do teste modal para obtenção da Função Resposta em Freqüência (FRF) em estruturas de baixas freqüências naturais utilizando como excitador um martelo instrumentado. Há duas necessidades conflitantes neste tipo de teste: de um lado, as baixas freqüências naturais da estrutura, usualmente associadas com baixo amortecimento, requerem um tempo longo de aquisição para haver boa resolução no espectro. Por outro lado, a taxa de amostragem deve ser elevada para captar corretamente o sinal de curta duração do martelo. Isto leva a um número elevado de pontos no sinal a ser adquirido, havendo eventualmente limitação de tal número de pontos ao se utilizar analisadores de espectro na aquisição e obtenção das FRFs. Neste sentido, neste trabalho foi explorada a técnica de decimação seletiva para aprimoramento do teste. O trabalho inclui a construção de um protótipo com dois Graus de Liberdade (S2GL) para servir como objeto de estudo para os testes deste aprimoramento, permitindo assim, comparar as Funções Resposta em Freqüências (FRF) teóricas e experimentais, bem como ajustar os parâmetros do modelo. Utilizou-se da linguagem de programação MATLAB® para a obtenção das FRFs. A eficiência do aprimoramento empregado foi verificada através dos espectros de freqüência, onde observou-se uma significativa similaridade entre a FRF não decimada com a aquisição possuindo um número elevado de pontos e a FRF decimada com menor número de pontos e selecionada de modo a preservar a correta detecção do sinal do martelo.

Previous issue date: 2010-04-07The environmental crisis we are experiencing brought the need for paradigm shifts in modes of production. Farming constitutes one of the greatest forms of environmental impact, because its origin is based on the exploitation of natural resources. In the course of this matter, there are studies, since the adoption of the Land Statute, the social function of property has become a determinant in the guideline that it is for rural workers to explore the land seeking to improve their quality of life, contributing also for the welfare and conservation of natural resources. It is expected, along the thesis that the agricultural policy instruments, such as rural credit and forms of associations / cooperatives and the Draft Regional Sustainable Development (DRS's) are effective means to reach the sustainable in family farming, permanently. It is argued that, partnerships between Government, Banking Officers, Emater, FETAEG, Sebrae, unions, associations of producers and other actors of civil society organizations are the key for sustainable family farming to be a great exponent for the economic development of the country.
A crise ambiental que estamos vivenciando trouxe a necessidade de mudanças de paradigmas nos modos de produção. A atividade agrícola se constitui numa das formas de maior impacto ambiental, pois tem sua origem na exploração dos recursos naturais. Na disciplina dessa matéria, verificam-se estudos, desde a aprovação do Estatuto da Terra, que a função social da propriedade tornou-se diretriz determinante no sentido de que cabe ao trabalhador rural explorar a terra buscando a melhoria da sua qualidade de vida, contribuindo também para o bem estar social e a conservação dos recursos naturais. Defende-se, ao longo da dissertação, que os instrumentos da política agrícola, tais como o crédito rural e as formas de associativismo/cooperativismo e os Projetos de Desenvolvimento Regional Sustentável (DRS s), são meios eficazes para se atingir a Sustentabilidade na agricultura familiar, de forma permanente. Defende-se ainda que, parcerias entre Governo, Bancos Oficiais, Emater, FETAEG, Sebrae, Sindicatos, Associações de produtores e demais agentes da sociedade civil organizada são fundamentais para que a agricultura familiar sustentável seja um grande expoente para o desenvolvimento econômico do País.

The principle of sustainable development, hosted by Federal Constitution of 1988, and in its Article 225, is essential issue in discussions about policies of economic, social and environmental development. Imposes upon the Government and the community have the duty to protect the environment and preserve it for present and future generations. In a globalized society, a socially responsible company, has a vital role in promoting sustainable development, and the contract, the trade instrument used for the production of wealth, should include clauses that would reduce the risks inherent in the business activity. From the hypothetical-deductive-teleological method, extensive research based on law, doctrine and jurisprudence, allow us to conclude that the inclusion of sustainability clauses in contemporary contract, comply with the standard and constitutional principles, being therefore, effective and capable of promoting sustainable development, and may even justify the termination of a contract for breach of contract.
O princípio do desenvolvimento sustentável, acolhido pela Constituição Federal de 1988, e presente em seu no artigo 225, é assunto indispensável em discussões acerca de políticas de desenvolvimento econômico, social e ambiental. Impõe ao Poder Público e à coletividade o dever de defesa do meio ambiente, bem como de preservá-lo para as presentes e futuras gerações. Em uma sociedade globalizada, a empresa socialmente responsável, tem um papel vital na promoção do desenvolvimento sustentável, e o contrato, instrumento utilizado pelo comércio para a produção de riquezas, devem incluir cláusulas que possam afastar os riscos inerentes à atividade empresarial. A partir do método hipotético-dedutivo-teleológico, a extensa pesquisa baseada na lei, na doutrina e na jurisprudência, nos permitem concluir que, a inclusão das cláusulas de sustentabilidade no contrato contemporâneo, estão de acordo com a norma e os princípios constitucionais, sendo, portanto, eficazes e capazes de promover o desenvolvimento sustentável, podendo, inclusive, fundamentar a resolução de um contrato por inadimplemento contratual.

Previous issue date: 2007-05-22This paper aims at studying the persuasive language of horoscopes from online versions of the following American newspapers: Los Angeles Times, New York Daily News, Chicago Tribune and San Francisco Chronicle. 2544 horoscopes have been selected during 53 days, and 943 conditional structures have been found. Latour and Woolgar (1979) state that the objective of rhethoric persuasion is to convince the participants that they haven t been convinced, and Halliday (1985) points out that persuasion tends to be highly implicit and to avoid attitudinal language, which is usually associated with interpersonal meaning. The horoscope is a text genre, thus, according to Martin (1984), it can be separated in stages, each of those with its specific function. 37,06% of the analized horoscopes present some kind of conditional structure, with the explicit connector, if (30,75%), or implicit ones (69,25%). Protasis occurs, mostly (71,15%), preposed to the apodosis, functioning as sentence Themes, and, therefore, restricting the content of the Rhemes. The language of horoscopes also presents elements of metadiscursive modality, such as person markers, hedges and emphatics. Besides, one of the stages consists of a kind of truth, a belief that has its roots in polular culture and that helps the reader rescue a specific intertext that the hosroscope writer previously had in mind. In addition, there is the theory of frames (Bednarek, 2005), responsible for text coherence which is attributed, in this case, by the text readers -, that focuses on the relation among text, context, world knowledge, and coherence. Thus, by reading a horoscope, the reader interacts with the text, giving it the most coherent meaning according to their own world knowledge. These factors prepare the readers for the reading and, therefore, they do not question what has been predicted by the author and, at the same time, they act impelled by the power of this genre. The same factors also prevent the horoscope writers from making mistakes regarding their predictions. All that makes horoscopes a highly pesuasive text genre.This kind of persuasion is implicit, for it makes use of a combination of specific lexico-grammatical choices and specific contexts. Regarding the lexico-grammar, this paper focuses on structures that convey conditional meanings, emphasizing Géis s (1971) concept of invited inferences and the relation between conditional structures and Theme, and conditional meaning. It also refers to Critical Discourse Analysis (Fairclough, 1992; Fowler, 1991), concerning the social function of language, and to Halliday s (1985; 1994) functional model, for the connection between language structures and social values. People are interested in horoscopes because they seem to work as a source for advice and entertainment as, according to Spengler (1969), religious faith has been replaced by other beliefs. The metodology adopted is interpretative, based on quantitative data
Esta pesquisa propõe-se a estudar a linguagem persuasiva dos horóscopos, coletados online, dos seguintes jornais dos Estados Unidos: Los Angeles Times, New York Daily News, Chicago Tribune and San Francisco Chronicle (USA). Foram compilados 2544 horóscopos, durante 53 dias e foram encontradas 943 construções condicionais. Latour e Woolgar (1979) afirmam que o objetivo da persuasão retórica é convencer os participantes de que não foram convencidos e Halliday (1985) aponta que a persuasão tende a ser altamente implícita e a evitar a linguagem atitudinal normalmente associada ao significado interpessoal. O horóscopo é um gênero, e, assim, de acordo com a definição de Martin (1984), divide-se em estágios, cada um com sua finalidade específica. Dos horóscopos examinados, 37,06% apresentam a construção condicional, com conectivo explícito, isto é, com se (30,75% dos casos) ou implícito (69,25% dos casos). A prótase ocorre, na maioria dos casos (71,15%), anteposta à apódose, funcionando, portanto, como tema, ou seja, determinando o conteúdo do rema. Por outro lado, a linguagem do horóscopo conta com a modalidade do metadiscurso, através de marcadores pessoais, hedges e enfatizadores. Além disso, um dos estágios reflete na maioria dos casos uma verdade, uma crença arraigada na cultura popular, que ajuda a fazer o leitor recuperar um intertexto, evidentemente, pretendido pelo autor do texto. A isso, junta-se a noção de enquadres (Bednarek, 2005), responsável pela coerência do texto, que é, segundo ela, atribuída por parte dos leitores e ouvintes, focalizando a relação entre texto, contexto, conhecimento de mundo e coerência. Assim, ao ler um horóscopo, o leitor interage com o texto e dá a ele o significado mais coerente de acordo com seu conhecimento de mundo. Esses fatores concorrem para que, assim condicionados, os leitores não questionem as previsões do astrólogo e ajam guiados pela força do gênero, e para que o escritor possa esquivar-se da responsabilidade por eventuais falhas que seus prognósticos apresentem, fazendo do horóscopo, portanto, um gênero altamente persuasivo. A esse tipo de persuasão denomina-se implícita, pois ocorre graças a escolhas léxico-gramaticais, que, combinadas a contextos específicos, tornam o texto persuasivo. Nesse sentido, quanto à léxico-gramática, focamos a escolha de estruturas que expressam condicionalidade, enfatizando o conceito de inferências convidadas de Géis (1971) e abordando a relação entre a construção condicional e o Tema e a expressão da condicional. Também há referência à análise crítica do discurso, com Fairclough (1992) e Fowler (1991) referindo-se ao funcionamento social da língua e ao modelo funcional desenvolvido por Halliday (1985; 1994) e seus pesquisadores para o exame da conexão entre estrutura lingüística e valores sociais. As pessoas voltam-se à astrologia por meio dos horóscopos com as finalidades de entretenimento e aconselhamento, já que, segundo Spengler (1969), a fé religiosa é substituída por outras crenças à medida que o homem se dá conta de que a vida não tem sentido após a morte. A metodologia adotada para a análise dos dados tem cunho interpretativista, com base em dados quantitativos

Executive functions (EF) are an abilities set, including selective attention, cognitive flexibility, inhibitory control, planning, monitoring and working memory, among others, whose function is to regulate and control goals oriented behaviors. There are evidences that these abilities follow distinct developmental paths, and some of them still are in full development until the initial adulthood. In this way, this study aimed to investigate the development tends of different abilities of the EF in children and adolescents, searching for validity evidences of neuropsychological assessment instruments of these abilities. The participants were 572 children and adolescents with ages between 6 and 14 years, students of 1st to 8th grades of two public schools of a city of the SP interior. The instruments utilized were Auditive Work Memory Test, Visual Work Memory Test, Cancel Attentional Test, Trail Making Test parts A and B, Semantic Generation Test, Computerized Stroop Test, the Tower of London and the FAS Verbal Fluency Test. The Cancel Attentional Test and Trail Making Test parts A and B were applied collectively; the others, individually. Variance analysis and Kruskal-Wallis analysis revealed age effect in the performances in all instruments. The data suggested that the abilities evaluated follow developmental courses lightly distinct, the most initiating a more abrupt development between the 9 and 10 years. Mann-Whitney analysis showed that the girls were better that the boys in the auditive working memory, alternated attention and verbal fluency measures. Diverse significant correlations were find between the performances, the most of them were of low to moderate, corroborating the literature that defends the notion of the EF unit and diversity. Exploratory Factorial Analysis returned a two factors solution and regression analysis enabled the verification that the executive abilities can contribute of differential ways to the complex task performance, like as the FAS Verbal Fluency Test and the Tower of London Test. In this way, the study provided his contributions to the knowledge about EF and its development, as well derived validity evidences to the diverse instruments and, it‟s a hope, can expand its contribution to the future availability of adequate instruments for the construct assessment.
Funções executivas (FE) designam um conjunto de habilidades, incluindo atenção seletiva, flexibilidade cognitiva, controle inibitório, planejamento, monitoramento e memória de trabalho, dentre outros, cuja função é regular e controlar comportamentos orientados a metas. Há evidências de que estas habilidades seguem distintas trajetórias desenvolvimentais, sendo que algumas ainda estão em pleno desenvolvimento até a idade adulta inicial. Destarte, este estudo tem por objetivo investigar tendências de desenvolvimento dos diferentes processos que integram as FE em crianças e adolescentes, buscando evidências de validade de instrumentos de avaliação neuropsicológica de tais habilidades. Participaram 572 crianças e adolescentes com idades entre 6 e 14 anos, estudantes de 1ª a 8ª série de duas escolas públicas de uma cidade do interior de SP. Foram utilizados os instrumentos: Teste de Memória de Trabalho Auditiva, Teste de Memória de Trabalho Visual, Teste de Atenção por Cancelamento, Teste de Trilhas partes A e B, Teste de Geração Semântica, Teste de Stroop Computadorizado, Torre de Londres e Teste de Fluência Verbal FAS. Os instrumentos Teste de Atenção por Cancelamento, Teste de Trilhas partes A e B foram aplicados coletivamente; os demais, individualmente. Análises de Variância e de Kruskal-Wallis revelaram efeito da idade sobre os desempenhos em todos os instrumentos. Verificou-se que as habilidades avaliadas seguem cursos desenvolvimentais levemente distintos, a maioria iniciando um desenvolvimento mais abrupto entre os 9 e 10 anos. Análise de Mann-Whitney evidenciou que as meninas foram melhores que os meninos nas medidas de memória de trabalho auditiva, atenção alternada e fluência verbal. Diversas correlações significativas foram evidenciadas entre os desempenhos, a maioria delas de baixas a moderadas, corroborando a literatura no que tange à noção de unidade e diversidade das FE. Análise Fatorial exploratória retornou uma solução de dois fatores e análises de regressão possibilitaram a constatação de que as habilidades executivas podem contribuir de modo diferencial ao desempenho em tarefas complexas, como o Teste de Fluência Verbal FAS e Teste da Torre de Londres. Deste modo, o estudo proveu contribuições ao conhecimento sobre FE e seu desenvolvimento, bem como derivou evidências de validade aos diversos instrumentos e, espera-se, possa expandir sua contribuição à futura disponibilização de instrumentos adequados à avaliação do construto.

Full textAbstract:
Aspherical optics are increasingly used these days. The application of aspherical surfaces on large, astronomical telescope mirrors brings challenge to the fabrication. Since the surface radius of curvature varies across the surface, the grinding/polishing tool needs to change its shape when working on different parts of the surface, making surface error more easily embedded into the surface. Therefore, a tighter test-fab loop is needed to guide the fabrication process. To maximize the accuracy during the grinding of the surface and to minimize the working time in the polishing stage, a better metrology device that can measure rough surface is needed to guide the grinding process. Scanning long-wave optical test system (SLOTS) is designed to meet this demand by providing accurate, fast, large dynamic range, and high spatial resolution measurements on rough optical surfaces (surface rms roughness<1.7 µm).SLOTS is a slope measuring deflectometry system that works like a reversed wire test. It measures the reflection of the infrared light off the test surface, and calculates the local slope of the test surface. The surface sag/height is obtained through integration. During the test, a heated metal ribbon radiates long-wave infrared light that is reflected by the test surface. A thermal imaging camera records the reflected light. The ribbon is scanned in two orthogonal directions. From the variation of the irradiance recorded by the camera, slope maps of the test surface can be retrieved in the two orthogonal directions. SLOTS is a combination of tradition slope measurement and modern technology, processing advantages from both parts. It measures surface slope, so there is no need for null optics. It uses an uncooled thermal imaging camera that is made with high resolution and high sensitivity. The linear stage used to scan the hot ribbon has long travel, small resolution, and high accuracy. Both the camera and stage enable SLOTS a large dynamic range and high sensitivity. SLOTS has successfully guided the grinding process of the primary mirror of Daniel K. Inouye Solar Telescope. This mirror is a 4-meter diameter off-axis parabola (OAP). Its largest aspherical departure is 8 mm. SLOTS is able to measure it without any null optics. Under the guidance of SLOTS, the surface shape was controlled to be 1 µm rms within designed shape (with astigmatism removed) at 0.7 µm rms surface roughness (12 µm loose abrasive grits).

2011/2012The present work pertains to the surface science approach to heterogeneous catalysis. In particular model systems for CO2 hydrogenation to methanol, and NO selective catalytic reduction, are investigated by means of a combined approach, where the molecular-level insight provided by a low-temperature scanning tunneling microscope is complemented by density functional theory (DFT) calculations of their electronic structure. To this end, the Inelastic Electron Tunneling Spectroscopy (STM-IETS) technique was introduced for the first time in our laboratory, a recent development which allows to measure the vibrational spectrum of individual molecules adsorbed on a surface. Regarding CO2, we provide single molecule imaging and characterization of CO2/Ni(110), chemisorbed with high charge transfer from the substrate, in an activated state that plays a crucial role in the hydrogenation process. We obtain a detailed characterization of the adsorption geometries and an estimate of the energies corresponding to the different adsorbed states. A consistent picture of CO2 chemisorption on Ni(110) is provided on the basis of the newly available information, yielding a deeper insight into the previously existing spectroscopic and theoretical data. In the Selective Catalytic Reduction (SCR) process, nitrogen oxide is selectively transformed to N2 by reductants such as ammonia. The specificity of this reaction was tentatively attributed to the formation of NH3-NO coadsorption complexes, as indicated by several surface science techniques. Here we characterize the NH3-NO complex at the atomic scale on the (111) surface of platinum, investigating the intermolecular interactions that tune the selectivity. The structures that arise upon coadsorption of NH3 and NO are analyzed in terms of adsorption sites, geometry, energetics and charge rearrangement. An ordered 2 × 2 adlayer forms, where the two molecules are arranged in a configuration that maximizes mutual interactions. In this structure, NH3 adsorbs on top and NO on fcc-hollow sites, leading to a cohesional stabilization of the extended layer by 0.29 eV/unit cell. The calculated vibrational energies of the individually-adsorbed species and of the coadsorption structure fit the experimental values found in literature within less than 6%. The characterizations and optimizations that had to be tackled in order to successfully perform STM-IETS measurement are eventually presented, focusing in particular on an original method which allows to increase the achieved resolution. Namely, the modulation broadening associated to phase-sensitive detection is reduced by employing a tailored modulation function, different from the commonly-used sinusoid. This method is not limited to STM-IETS, but can be easily applied whenever a lock-in amplifier is used to measure a second derivative.

Full textAbstract:
El sector hospitalari públic és el majoritari tant a Catalunya com a Espanya. En aquest entorn no s'ha primat l'anàlisi dels costos de la provisió de serveis de salut. La variabilitat dels costos i la definició de producte hospitalari s'ha basat en els Sistemes de Classificació de Pacients (SCP) i més concretament, en els Grups Relacionats amb el Diagnòstic (GRD). La hipòtesi de treball ha estat que la variabilitat deguda a la complexitat del procés de producció hospitalari no queda ben reflectida amb l'ús dels SCP ja que només aporten informació sobre la dimensió de la complexitat del concepte de producte hospitalari. Queden per explicar la seriositat de la malaltia, els outliers, els factors socioeconòmics, les característiques del procés, i els factors estructurals. Tots ells, junt amb l'ajust dels costos relatius (pesos) associats als GRD, poden explicar molt millor la variabilitat del cost hospitalari basat en al definició correcta del producte.
S'ha analitzat una base de dades corresponent als hospitals de l'Institut Municipal d'Assistència Sanitària, amb 35.262 casos i 12.792 milions de pessetes assignats a pacient mitjançant una metodologia d'assignació basada en activitats (cost sobre base clínica).
S'ha determinat que:
- La capacitat explicativa de la variabilitat del cost dels pacients analitzats ha augmentat des del 19% mitjançant GRDs i pesos associats estàndard, fins al 50% si introduïm el concepte integral de la definició de producte, incorporem la mesura de casos extrems i ajustem correctament el pesos a l'entorn europeu.
- S'ha modelitzat una funció de costos que permet analitzar el comportament de les diferents dimensions explicatives del producte i la seva influència sobre el cost per pacient.
Dels resultats s'han extret implicacions:
- La capacitat explicativa del cost no augmenta amb l'increment de categories dels sistemes de classificació de pacients, sinó que millora gràcies a l'explicació multidimensional del producte hospitalari. Així quants menys grups haguem de fer servir, més racional serà l'ús dels sistemes de classificació de pacients per a la gestió clínica, hospitalària i sanitària.
- L'absència d'informació individual sobre el component socioeconòmic del pacient resta capacitat explicativa de la variabilitat del cost hospitalari. Aquesta manca d'informació s'hauria de replantejar tot i els problemes ètics que presenta la seva utilització, ja que és causa de variabilitat justificable no recollida pels actuals sistemes d'informació. És, per tant, causa de risc financer per determinats hospitals.
Public hospital sector is the majority in Catalonia as well as in Spain. In this environment, cost analysis of health services supply was not considered an important issue. Cost variability and hospital product definition were based on Patient Classification Systems (PCS) and more specifically on Diagnosis Related Groups (DRG).
The initial hypothesis was that the variability due to complexity of hospital production process was not well reflected by using PCS because they only add information about the complexity dimension of hospital product concept. It remains to explain the seriousness of illness, outliers, socio-economic status, process characteristics and structural factors. All together, with cost-based DRG-Weight, can improve the explanation of hospital cost variability based on the appropriate product definition.
Database belonging to the Institut Muncipal d'Assistència Sanitària was analysed. The database includes 35,262 patients and 12.762 million pesetas assigned to them. The assignation was performed through a methodology based on activities (clinical-cost).
It was determined that:
- Explanatory power of cost variability for the analysed patients increased from 19% using DRG and Medicare weights, to 50% after introducing the integral concept of product definition, adding outlier cases measures and adjusting weights to the European environment.
- Cost function could be determined. This enabled to analyse the different product dimensions behaviour and their influence on per-patient cost.
The implications of the results were:
- Cost explanatory power does not increase by adding PCS categories, but do improve through the multidimensional explanation of hospital product. Thus, the less groups we use, more rational will be the PCS to the clinic, hospital and health system management.
- The absence of individual information of patient socioeconomic status undermines explanatory power of hospital cost variability. This information lack has to be reconsidered, although the ethic problems that its collection represents, since socio-economic status is a reason of some justified cost variability that is not included by current information systems. Thus, patient socio-economic status variability is a reason of financial risk for determined hospitals.

Esta dissertação consiste em dois estudos que têm por objetivo investigar a existência de disfunções executivas no envelhecimento. Estudos recentes sugerem a existência de disfunções executivas no Declínio Cognitivo Leve (DCL). O objetivo do Estudo 1 foi verificar a presença de disfunções executivas em pacientes com DCL. Os instrumentos utilizados foram o Teste Wisconsin de Classificação de Cartas (WCST) e a Iowa Gambling Test (IGT). Foram estudados dez pacientes com e 27 sem DCL. Os dados foram analisados através do teste t de Student para amostras independentes e da análise de variância (ANOVA) para medidas repetidas. Os resultados não evidenciaram diferença significativa entre os grupos nos índices de resposta do WCST e no número de cartas retiradas de cada baralho no IGT. O estudo da evolução do desempenho no IGT revelou diferença qualitativa entre os grupos. Idosos sem DCL aprendem ao longo da tarefa, enquanto idosos com DCL não o fazem, sugerindo uma interferência dos sistemas de memória na tomada de decisão. O Iowa Gambling Test tem sido um instrumento utilizado na avaliação da tomada de decisão. O objetivo do Estudo 2 foi investigar se alterações nos procedimentos de aplicação do instrumento interferem no desempenho durante a execução do teste. Foi realizado um estudo transversal comparando dois grupos de idosos saudáveis em duas variações do instrumento. O grupo I contou com 27 participantes, que executaram a tarefa sem pista de reforço visual. O grupo II foi composto por 17 participantes, submetidos à tarefa com pista. Os dados foram analisados através dos testes t de Student para amostras independentes e ANOVA para medidas repetidas. Houve diferença estatisticamente significativa entre os dois grupos na execução do teste em relação à aversão ao risco (F=2,466; p=0,05; df=2). Os resultados indicam que uma pista de reforço visual possibilita maior alocação de recursos atencionais e de memória de trabalho, permitindo que os idosos tomem decisões menos arriscadas.This dissertation is formed by two works that aim to investigate executive dysfunction on ageing. Recent studies suggest the existence of executive dysfunctions in Mild Cognitive Impairment (MCI). The aim of the first study was to verify the presence of executive dysfunctions in patients with MCI. The instruments used were the Wisconsin Card Sorting Test (WCST) and the Iowa Gambling Test (IGT). Ten patients with and 27 without MCI were assessed. The data were analyzed through Student t test for independent samples and analysis of variance (ANOVA) for repeated measures. The results did not show significant difference between groups in the answer rates of WCST and in the number of cards withdrawn from each pack of cards in the IGT. The study of the performance evolution in the IGT revealed a qualitative difference between the groups. Elderly without MCI learn along the task, while elderly with MCI did not, suggesting an interference of memory systems in decision making. The Iowa Gambling Test has been an instrument used in the assessment of decision making. The aim of the second study was to investigate if changes in the application procedures of the instrument interfere in the performance through the test execution. A cross sectional study was carried out comparing two groups of healthy elderly in two variations of the instrument. The group I included 27 participants, which executed the task without clue of visual reinforcement. The group II was composed by 17 participants, submitted to the task with clue. The data were analyzed through the Student t test for independent samples and ANOVA for repeated measures. It was found statistically significant difference between the two groups in the execution of the test in relation to risk aversion (F=2,466; p=0,05; df=2). The results indicate that a clue of visual reinforcement permits greater allocation of attention resources and of working memory, allowing elderly to make least risky decisions.

The present work is devoted to the study of the application of the constitutional instruments of induction of the fulfillment of the social function of the urban property foreseen in art. 182, namely: compulsory subdivision, building and use (PEUC); The progressive tax on land and urban property (IPT U) over time; And expropriation with payment through public debt securities. Since 2002, these instruments were foreseen in the Strategic Master Plan of São Paulo, but it was not until November 2014, after approval of a new Master Plan, that they were effectively applied by the municipal Executive Branch. Therefore, the objective of this work is to investigate the legal and political conditions that allowed the application by the municipality. Not only the legal arrangements that shaped the features of these instruments, but also factors of other orders that can be explained in the conflicts around this legislation at national and municipal level. The methodology sought to recover historical aspects of the legislative and political process that led to the positivation of these instruments in the Brazilian legal-urban order and in municipal legislation, using the literature review that analyzes the historical process. Equally important is the support of legal literature in the field of civil law and urban planning law with regard to the social function of property and the interpretation of the legal instruments that are the subject of the study. In the final chapters, due to the recent municipal experience and the scarce literature, documentary analysis and interviews were fundamental as a means of collecting information that is fundamental for understanding the experience studied. At the end of the work, one of the main results is the finding that the forecast in the legislation is an important but insufficient Step to ensure the application of these mechanisms. Political factors, influences from previous experiences, institutional capacity and resistance / support of social groups are factors that combine to make application feasible. In the case of São Paulo, it took twelve years for the conditions to present themselves more adequately for this purpose. However, after the notification of more than one thousand two hundred real estate, a new and more challenging stage begins, of managing the interests involved. We can see a research agenda that no longer has as a problem the positivization or regulation of the instruments, but its operationalization and the evaluation of the effectiveness of the properties to fulfill their social function
O presente trabalho dedica-se ao estudo da aplicação dos instrumentos constitucionais de indução do cumprimento da função social da propriedade urbana previstos no art. 182, a saber: o parcelamento, edificação e utilização compulsórios (PEUC); o imposto sobre a propriedade territorial e predial urbana (IPT U) progressivo no tempo; e a desapropriação com pagamento mediante títulos da dívida pública. Desde o ano de 2002, tais instrumentos foram previstos no Plano Diretor Estratégico de São Paulo, mas foi apenas em novembro de 2014, após aprovação de um novo Plano Diretor, que vieram a ser efetivamente aplicados pelo Poder Executivo municipal. Diante disso, o trabalho objetiva investigar as condições jurídicas e políticas que viabilizaram a aplicação por parte do município. Não apenas os arranjos legais que moldaram a feição desses instrumentos, mas igualmente fatores de outras ordens que podem ser explicados nos embates entorno dessa legislação no âmbito nacional e municipal. A metodologia buscou resgatar aspectos históricos do processo legislativo e político que levou à positivação desses instrumentos na ordem jurídico- urbanística brasileira e na legislação municipal, valendo-se para tal da revisão de literatura que faz uma análise desse processo histórico. Igualmente importante é o suporte da literatura jurídica no âmbito do direito civil e do direito urbanístico no que tange à função social da propriedade e à interpretação dos instrumentos jurídicos objeto do estudo. Nos capítulos finais, em razão de recente experiência municipal e da escassa literatura, fez-se fundamental a análise documental e a realização de entrevistas como forma de coletar informações fundamentais para a compreensão da experiência estudada. Ao fim do trabalho, um dos principais resultados é a constatação de que a previsão na legislação é uma etapa importante mas insuficiente para assegurar a aplicação desses mecanismos. Fatores políticos, influências de experiências anteriores, capacidade institucional e resistência / suporte de grupos sociais são fatores que se combinam para viabilizar a aplicação. No caso de São Paulo, foram necessários doze anos para que as condições se apresentassem mais adequadamente para esse fim. No entanto, após a notificação de mais de mil e duzentos imóveis, uma nova e mais desafiadora etapa se inicia, de gestão dos interesses envolvidos. Vislumbra-se uma agenda de pesquisa que já não mais tem como problema a positivação ou a regulamentação do instrumentos, mas a sua operacionalização e a avaliação sobre a eficácia para fazer com que os imóveis cumpram sua função social

Após o aumento de potência do reator IEA-R1 de 2 MW para 5 MW observou-se um aumento da taxa de corrosão nas placas laterais de alguns elementos combustíveis e algumas dúvidas surgiram com relação ao valor de vazão utilizada nas análises termo-hidráulicas. A fim de esclarecer e medir a distribuição de vazão real pelos elementos combustíveis que compõe o núcleo do reator IEA-R1, um elemento combustível protótipo, sem material nuclear, chamado DMPV-01 (Dispositivo para Medida de Pressão e Vazão), em escala real, foi projetado e construído em alumínio. A vazão no canal entre dois elementos combustíveis é muito difícil de estimar ou ser medida. Esta vazão é muito importante no processo de resfriamento das placas laterais. Este trabalho apresenta a concepção e construção de um elemento combustível instrumentado para medir a temperatura real nestas placas laterais para melhor avaliar as condições de resfriamento do combustível. Quatorze termopares foram instalados neste elemento combustível instrumentado. Quatro termopares em cada canal lateral e quatro no canal central, além de um termopar no bocal de entrada e outro no bocal de saída do elemento. Existem três termopares para medida de temperatura do revestimento e um para a temperatura do fluido em cada canal. Três séries de experimentos, para três configurações distintas, foram realizadas com o elemento combustível instrumentado. Em dois experimentos uma caixa de alumínio foi instalada ao redor do núcleo para reduzir o escoamento transverso entre os elementos combustíveis e medir o impacto na temperatura das placas externas. Dada a tamanha quantidade de informações obtidas e sua utilidade no projeto, melhoria e capacitação na construção, montagem e fabricação de elementos combustíveis instrumentados, este projeto constitui um importante marco no estudo de núcleos de reatores de pesquisa. As soluções propostas podem ser amplamente utilizadas para outros reatores de pesquisa.

Full textAbstract:
Terrorist organizations and individuals make use of the Internet for supportive activities such as communication, recruiting, financing, training, and planning operations. However, little is known about the level of computer-based (“cyber”) threat such terrorist organizations and individuals pose. One step in facilitating the examination and assessment of the level of cyber threat posed by terrorist organizations and individuals is development of an assessment tool or methodology. This tool would guide intelligence collection efforts and would support and facilitate comparative assessment of the cyber threat posed by terrorist organizations and individuals through the provision of a consistent method of assessment across time, amongst organizations and individuals, and between analysts. This study leveraged the professional experience of experts to engineer a new functional construct – a structured analytical technique designed to assess the cyber threat posed by terrorist entities and individuals. The resultant instrument was a novel structured analytical construct that uses defined indicators of a terrorist organization/individual’s intent to carry out cyber attacks, and their capability to actually do so as measures of an organization/individual’s overall level of cyber threat.

With improvements in actuation technology and sensory systems, it is becoming increasingly feasible to create powered exoskeletal garments that can assist with the movement of human limbs. This class of robotics referred to as human-machine interfaces will one day be used for the rehabilitation of paralysed, damaged or weak upper and lower extremities. The focus of this project was the development of an exoskeletal interface for the rehabilitation of the hands. A novel sensor was designed for use in such a device. The sensor uses simple optical mechanisms centred on a spring to measure force and position simultaneously. In addition, the sensor introduces an elastic element between the actuator and its corresponding hand joint. This will allow series elastic actuation (SEA) to improve control and safely of the system. The Hand Rehabilitation Device requires multiple actuators. To stay within volume and weight constraints, it is therefore imperative to reduce the size, mass and efficiency of each actuator without losing power. A method was devised that allows small efficient actuating subunits to work together and produce a combined collective output. This work summation method was successfully implemented with Shape Memory Alloy (SMA) based actuators. The actuation, sensory, control system and human-machine interface concepts proposed were evaluated together using a single-joint electromechanical harness. This experimental setup was used with volunteer subjects to assess the potentials of a full-hand device to be used for therapy, assessment and function of the hand. The Rehabilitation Glove aims to bring significant new benefits for improving hand function, an important aspect of human independence. Furthermore, the developments in this project may one day be used for other parts of the body helping bring human-machine interface technology into the fields of rehabilitation and therapy.

Full textAbstract:
The transformations of the property right unchained by the change of paradigm imposed by the Social Estate, together with it s population brutal increase, causing serious social problems, from the lack of housing to the insufficience and inefficiency of urban and communitarian equipment, made the constitutional principle of urban property social function to gain crucial importance in the brazilian constitucion. Because of that, the legislator concentrated efforts to regulate the carrying out constitutional instruments of the urban property social function, contemplated at article 182 §4º, I, II and III of the Federal Constitution, that respectively refers to the obligatory plotting or construction, to the urban bulding and territorial gradual tax in time and the dispossession, all of coercitive nature. With such mission appeared the Statute of the City Law 10.257/2001, that was put in charge of regulating the cited constitutional instruments, and therefore constitutes indispensable element for carrying out the urban property social function. In this dissertation, the constitutional instruments of coercitive nature are analised, under the view of carrying out the urban property s social function which, trough the detailed analysis of the appropriate law, passing trough the evolution of the urban property social function principle in brazilian constitutions, making use, as theoretician referencial, of the works from those that studied the legal aspects of the subject.A transformação do direito de propriedade desencadeada pela mudança de paradigma imposta pelo Estado Social, aliada ao crescimento desordenado das cidades, causando sérios problemas sociais que vão desde a falta de moradias, até a insuficiência e ineficiência de equipamentos urbanos e comunitários, fez com que o princípio da função social da propriedade urbana ganhasse importância crucial no constitucionalismo brasileiro. Em função disso, o legislador concentrou esforços para regulamentar os instrumentos constitucionais de efetivação da função social da propriedade urbana, contemplados nos incisos I, II e III do § 4º do art. 182 da Constituição Federal, que tratam, respectivamente, do parcelamento ou edificação compulsórios, imposto predial e territorial urbano progressivo no tempo e desapropriação, todos de natureza coercitiva. Com tal missão adveio o Estatuto da Cidade Lei nº 10.257/2001, a quem coube a regulamentação dos referidos instrumentos constitucionais, e que, por essa razão, constitui elemento indispensável para a efetivação da função social da propriedade urbana. Na presente dissertação, são abordados os instrumentos constitucionais de natureza coercitiva, com vista à efetivação da função social da propriedade urbana, por meio da análise detalhada da legislação regulamentadora, passando pela evolução do princípio da função social da propriedade urbana nas constituições brasileiras, utilizando como referencial teórico a produção doutrinária dos que se debruçaram sobre os aspectos jurídicos pertinentes ao tema.

A preparação de obras para violão compostas em afinações não tradicionais é comumente considerada uma tarefa complexa. Dependendo da afinação, a disposição das notas ao longo da escala do instrumento pode vir a se alterar radicalmente. Isso interfere diretamente na preparação de uma obra, desde os momentos iniciais da leitura, passando pelo processo de digitação e também de memorização. A presente pesquisa teve como objetivo investigar a eficácia de diferentes estratégias de estudo durante a abordagem inicial de peças para violão com scordaturas não usuais, por oito violonistas de diferentes níveis acadêmicos. Outros objetivos incluem identificar os problemas comuns aos violonistas durante o estudo de obras com scordatura e investigar se a formação prévia exerce influência no aprendizado de obras com afinações não tradicionais. Para a coleta de dados, duas sessões de estudo individuais foram realizadas. Cada sessão consistiu no estudo de trechos musicais, seguido da performance do trecho estudado e de uma entrevista semiestruturada. Foi também aplicado um questionário cujo objetivo era acessar os dados históricos referentes à experiência musical dos Sujeitos. No primeiro encontro, foi permitido aos Sujeitos conduzir o estudo deliberadamente, com o objetivo de prepará-lo no menor tempo possível. No segundo encontro, os Sujeitos receberam estratégias de estudo previamente estabelecidas para cada trecho. As sessões, performances e entrevistas foram filmadas. Os níveis de formação foram determinantes na qualidade dos produtos finais da sessão de estudo deliberado. O uso das quatro estratégias gerou performances com menor diferença qualitativa entre Sujeitos de diferentes níveis acadêmicos. Também, a eficácia destas foi influenciada pela sua adequação à textura e idioma harmônico das peças. As entrevistas e questionários evidenciaram, também, que o perfil de aprendizado de cada Sujeito, no que concerne a sua relação com o estudo, o uso individual de representações mentais, anotação de guias de estudo na partitura, bem como sua trajetória musical, influenciam o modo como diferentes estratégias podem ou não ser eficazes, independentemente do detalhamento da informação que elas disponham na partitura.The learning of guitar works composed in nontraditional tunings is commonly considered a complex task. Depending on the tuning, the arrangement of notes along the instrument fretboard can change radically. It interferes directly in the preparation of a work from the initial reading moments and through the processes of fingering and memorization. The purpose of this research was to investigate the effectiveness of different study strategies during the initial approach to guitar works with unusual scordaturas by eight guitarists of different academic levels. Other objectives included identifying common problems for guitarists during the study of works with scordatura and investigating whether prior training influences the learning of works with nontraditional tunings. For data collection, two separate meetings were held. Each meeting consisted of a session of study of musical excerpts, followed by the performance of the studied excerpt and a semi-structured interview. A questionnaire was applied with he purpose to access the musical experience of the subjects. In the first meeting, subjects were allowed to conduct the study deliberately, in order to prepare the piece in the shortest time possible. In the second meeting, the subjects received study strategies previously established for each piece. The meetings, performances and interviews were filmed. Different academic levels determined the quality of the final products of the first study session. The use of four strategies generated performances with less qualitative differences between the subjects, regardless of their academic level. Also, the effectiveness of these was influenced by its capacity to fit effectively the texture and harmonic idiom of the pieces. Interviews and questionnaires showed also that the learning profile, the individual use of mental representations, the use of study guides in the score and the musical background of each subject, have influenced how different strategies may or may not be effective, regardless of how much information they provide in the score.

Full textAbstract:
As opportunities to perform as a soloist diminish, more pianists consider chamber and orchestral playing as an alternative solution. By so doing, ample performance opportunities are introduced. Although most university music programs offer ensemble courses for pianists and have begun to offer degrees with an emphasis in accompaniment, their curriculum lacks instructions specifically designed to train and prepare pianists for playing in large ensembles, especially wind bands. This dissertation addresses the difficulties, which one might encounter in large ensemble collaboration, and recommends useful suggestions for acquiring functional skills to solve these difficulties. Pianists can attain professional status by acquiring the functional skills presented in each chapter. The goal of this study is to provide pedagogical support and direction for novice pianists in the larger ensemble collaboration.

Introduction: Our hypothesis is that patients with MG present a poor sleep due to the presence of respiratory disorders, compromised by the weakness of the ventilatory muscles, causing worsening of the clinical condition and quality of life. Objectives: To investigate the physiological pattern of sleep through polysomnography, to verify pulmonary function and ventilatory muscle strength through spirometry and manovacuometry, and to perform the translation, cultural adaptation and validation of two specific scales to evaluate the clinical evolution of patients with MG, denominated "Quantitative Test for Myasthenia Gravis" and "Composite Scale for Myasthenia Gravis". Material and methods: This is a cross-sectional study involving patients with MG. Clinical evaluations were performed at the UNINOVE Sleep Laboratory, at the Neuromuscular Diseases Research Unit at UNIFESP, at the Santa Casa de São Paulo Department of Neurology and at the Department of Neurology at the Hospital do Servidor Público Estadual of São Paulo. Results: The results of this thesis are separated into three studies. Study I: article entitled "Sleep, lung function and quality of life in patients with Myasthenia gravis: A cross-sectional study" published in the journal Neuromuscular Disorders. Study II: entitled "Brazilian- Portuguese translation, cross-cultural adaptation and validation of the Myasthenia Gravis Composite scale. A multicentric study." published in the journal Arquivos de Neuropsiquiatria. Study III: entitled "Quantitative Myasthenia gravis Score: a Brazilian multicenter study for translation, cultural adaptation and validation", published in the journal Arquivos de Neuropsiquiatria. Conclusion: Patients with MG presented a considerable presence of DRS with worsening quality of life. They presented reduced values in the maximum ventilatory pressures associated with normal values of pulmonary function. The translation and validation of the scales were performed successfully and we believe that the use of our Portuguese version from Brazil will assist in the care of patients with MG, including a more accurate monitoring of the clinical rehabilitation process.
Introdução: Nossa hipótese é que os pacientes com MG apresentam um sono de má qualidade devido a presença de distúrbios respiratórios, comprometido pela fraqueza dos músculos ventilatórios acarretando em piora da condição clinica e qualidade de vida. Objetivos: Investigar o padrão fisiológico do sono através da polissonografia, verificar a função pulmonar e a força muscular ventilatória através de espirometria e manovacuometria e realizar a tradução, adaptação cultural e validação de duas escalas específicas para avaliar a evolução clínica de pacientes com MG, denominados “Teste Quantitativo para Miastenia gravis" e "Escala composta para Miastenia gravis". Material e métodos: Trata-se de um estudo transversal envolvendo pacientes com MG. As avaliações clínicas foram realizadas no Laboratório do sono da UNINOVE, no Setor de Investigação de Doenças Neuromusculares da UNIFESP, no Departamento de Neurologia da Santa Casa de São Paulo e no Departamento de Neurologia do Hospital do Servidor Público Estadual de São Paulo. Resultados: Os resultados desta tese são separados em três estudos. Estudo I: artigo intitulado "Sono, função pulmonar e qualidade de vida em pacientes com Miastenia gravis: Um estudo transversal" publicado no periódico Neuromuscular Disorders. Estudo II: intitulado "Tradução, adaptação cultural e validação da escala Composta de Miastenia gravis para a língua portuguesa do Brasil: estudo multicêntrico" publicado no periódico Arquivos de Neuropsiquiatria. Estudo III: intitulado "Teste Quantitativo para Miastenia gravis: estudo multicêntrico brasileiro para tradução, adaptação cultural e validação. " publicado no periódico Arquivos de Neuropsiquiatria. Conclusão: Os pacientes com MG apresentaram uma presença considerável de DRS com piora na qualidade de vida. Apresentaram valores reduzidos nas pressões máximas ventilatória associados com valores normais de função pulmonar.

Full textAbstract:
Purpose: The purpose of the study was to investigate how companies are affected by currency hedging in international trade. One purpose was to investigate and identify the type of currency risks companies are most exposed to and what currency hedging methods are used to handle these. Methodology: To answer the study's question, research was conducted by using a qualitative data method and a content analysis method. Theoretical framework: The focus has been on these theories; Modigliani and Miller theory, currency risk management and previous studies. Result: The result of the study consists of a presentation of the processed data as underlies the analysis being carried out. Conclusion: The study found that the currency exposures which companies are primarily exposed to in international trade are transaction and translation exposures. Of the eight companies investigated in the study, seven of them focused on transaction exposure. The study also indicates that the most commonly used derivative instruments used by companies are futures, options and swaps, where futures due to its flexibility came first, options on the second place and swaps on the third place. The most important and used purchase currencies that the companies deal with are Euro, British pound and US-dollars. Whether it is profitable for companies to hedge their currency risks or not, this study found that currency hedging is profitable for companies.Syfte: Syftet med studien var att undersöka hur företagen påverkas av valutasäkring vid internationell handel. Ett delsyfte var att undersöka och kartlägga vilken typ av valutarisk företagen är mest exponerade för samt vilka valutasäkringsmetoder som används vid hantering av dessa. Metod: För att besvara studiens frågeställning genomfördes forskningen genom en kvalitativ metod och en innehållsanalysmetod. Teoretiskt perspektiv: Fokus har legat på dessa teorier; Modigliani & Millers teori, valutariskhantering och tidigare studier. Empiri: Empirin innefattar den bearbetade datan som har samlats in från respektive företag samt är grunden för studiens analys. Slutsats: Studien kom fram till att den valutaexponering som företagen främst utsätts för vid internationell handel var transaktions-och omräkningsexponering. Av de åtta företag som har undersökts i studien visade sig att sju av dessa fokuserade på transaktionsexponering. Studien visade även att de vanligaste derivatinstrumenten som används av företagen var terminer, optioner och swappar. Terminer på grund av dess flexibilitet kom på första plats, optioner på andra plats och swappar på tredje plats. De viktigaste och mest använda inköpsvalutorna som företagen handlar med var euro, brittiskt pund och amerikanska dollar. Huruvida det är lönsamt för företagen att valutasäkra eller inte, tydde denna studies fynd på att valutasäkring är lönsamt för företag.

A Sociedade e o mercado de trabalho exigem de cidadãos e trabalhadores, nos últimos tempos, um perfil de desempenho diferente daquele até então aceito. As principais carências do trabalhador dizem respeito, dentre outras necessidades, ao desempenho de certas competências pessoais e a melhoria do funcionamento cognitivo. As escolas, responsáveis pela preparação dessas pessoas para viver em Sociedade - o que inclui a preparação para o mundo do trabalho - não costumam realizar ações educacionais intencionais na direção da melhoria do desenvolvimento cognitivo de seus alunos. O foco do presente estudo está na possibilidade da Escola realizar intencionalmente o desenvolvimento cognitivo de estudantes, futuros trabalhadores. utilizando um programa já existente, criado e estruturado para essa finalidade por Reuven Feuerstein. No final da década de 1940, coube a Feuerstein a tarefa de educar centenas de crianças e jovens, órfãos da guerra, para que se tornassem cidadãos autônomos e produtivos. Diante da necessidade real de modificar o desempenho cognitivo e resgatar a cidadania dessas pessoas, Feuerstein criou - a partir de sua visão de mundo, de um conjunto de crenças por ele estabelecido e de sua experiência - duas teorias: Modificabilidade Cognitiva Estrutural e Experiência de Aprendizagem Mediada e três sistemas inter-relacionados, ou seja, um sistema de avaliação: Avaliação Dinâmica do Potencial de Aprendizagem, um sistema de intervenção: Programa de Enriquecimento Instrumental e um sistema de manutenção: Modelagem de Ambientes Modificadores. Avaliar o efeito do primeiro nível do Programa de Enriquecimento Instrumental (PEI I) no desenvolvimento cognitivo de estudantes da 3ª série de Escolas pública ou privada de Ensino Médio é o objetivo amplo desse trabalho. Em resumo, foram envolvidos no projeto 96 estudantes (54 rapazes e 42 moças) de duas Escolas de Ensino Médio: uma privada e outra pública. Sessenta e sete desses alunos participaram dos grupos experimentais que se submeteram ao PEI I e as outras 29 pessoas integraram grupos de controle, não participando, portanto, da aplicação do Programa. Todos os estudantes participaram de uma avaliação inicial diante de seis instrumentos, sendo que alguns deles permitiam avaliação dinâmica. Da análise dos resultados dos instrumentos, que envolviam avaliação dinâmica, foram levantadas necessidades e estabelecidos procedimentos de intervenção. Os alunos dos grupos experimentais foram submetidos ao primeiro nível do Programa de Enriquecimento Instrumental (PEI I). Durante a aplicação do PEI I, alunos participaram de avaliação intermediária, realizada a partir da aplicação de instrumento de avaliação e ou de questionário para levantamento da percepção dos estudantes sobre o PEI. Finalmente, todos os participantes foram submetidos a uma avaliação final. Os resultados foram analisados de forma descritiva e estatística. Os testes U ou de Mann- Whitney e o teste t de Student foram utilizados para indicar semelhanças e diferenças prováveis entre os desempenhos dos grupos de alunos. A partir da discussão desses resultados foram montadas proposições que justificaram as seguintes conclusões: A modificabilidade cognitiva estrutural dos estudantes dos grupos experimentais foi ampliada. O desenvolvimento cognitivo demonstrado pelos estudantes dos grupos experimentais foi maior que o desempenho cognitivo demonstrado pelos alunos do grupo de controle.In the recent past, both society and labour market are demanding from citizens a performance far different from those accept until then. The major lacks of workers may concern, among others, to the development of specific personal competences and to the improve of the cognitive process. Schools, responsible for the preparation for life in society - including the life in the labour market - don\'t usually take intentional educational actions aiming the improve of the cognitive development of their students. The focus of the present study is mainly on analyzing the possibility of Schools to make an intentional effort to develop student\'s cognitive habilities, future workers, using a preexisting program created and structured for this meaning by Reuven Feuerstein. In the late 40\'s, Feurstein took the task of teaching hundreds of children and teenagers, war orphan children, to become autonomous and productive citizens. Facing the real need of improving their cognitive habilities and rescuing their citizenship, Feuerstein came up - using his own wide world perception, personal beliefs and experience - with two theories: Structural Cognitive Modifiability (SCM) and Mediated Learning Experience (MLE) and three interrelated systems, or an evaluation system: Learning Potential Assesment Device (LPAD), an interventional system: Feuerstein Instrumental Enrichment (FIE) and a maintenance system: Shaping Modifying Environments (ME). The aim of this paper is to evaluate the effect of the first level of the Feuerstein Instrumental Enrichment (FIE I) on 3rd grade public or private High School student\'s cognitive development. Summing up, there were 96 students involved in this project (54 boys and 42 girls) from two different High Schools: one private and one public. Sixty seven of these students were placed on experimental groups that were submitted to FIE I and the other 29 kids took part on control groups, staying away from the program application. All the students participated on an initial evaluation, facing six instruments, some of then allowing a dynamic evaluation. From the instrument result analysys, needs were raised and intervention procedures were established. The students\'s experimental group was submitted to the first level of the Feuerstein Instrumental Enrichment (FIE I). During its application, the students had an intermediary evaluation, made by the application of the evaluation instrument and by a questionnaire to measure the student\'s level of perception about the (FIE I). Finally, all the participants were submitted to a final evaluation. The results were analyzed in a descriptive statistical way. The U or Mann-Whitney tests and the t for Student test were used to indicate probable similarities and differences among the student\'s groups performances. From its discussion were put together propositions to justify the following conclusions: The student\'s experimental group structural cognitive modifiability was raised. The cognitive development shown by the student\'s experimental group was higher than the cognitive performance shown by the student\'s control group.

Full textAbstract:
Valutamarknaden är världens största marknad och en nödvändig del av dagens globala samhälle, som gör det möjligt för företag att göra affärer i olika valutor och mellan olika gränser. Marknaden utgör en stor handelsplattform för både små och stora aktörer, för vilka det är viktigt att prognostisera valutakurser med gott resultat. Att modellera finansiella instrument i form av tidsserier är en av de vanligaste investeringsstrategierna och dess användningsområde sträcker sig från valutamarknaden till bland annat aktiemarknaden och råvarumarknaden. I denna uppsats undersöks fyra olika statistiska metoder för att modellera valutakursen Euro-US Dollar givet historisk data, och prognoser görs med de framtagna modellerna. Dessa metoder är slumpvandring, ARIMA, ARIMA-GARCH och VAR. Vidare undersöks för den dynamiska VAR-modellen hur valutamarkanden påverkar, och blir påverkad av, långa och korta räntan. Resultaten visar att ARIMA(3,1,2) förklarar valutakursen bäst medan VAR(2) med valutakursen och skillnaden mellan långa räntor som ingående variabler ger de bästa prediktionerna.The foreign exchange market is the world’s largest market and is an essential part of the global society of today. The FX market enables companies to trade with different currencies across country borders. It is also a large trade-platform for both big and small financial actors, who greatly benefit from the advantages of good predictions. Modeling of financial instruments is one of the most commonly used investment strategies and its area of application ranges from the FX market to markets suchas the stock market and the commodity market. In this paper, four different statistical models are used to model the currency pair Euro-US Dollar. These methods are random walk, ARIMA, ARIMA-GARCH and VAR. Besides investigating which method that gives the best forecasts, the method that best describes the training datais also found. Furthermore, for the dynamic VAR model, it is explored how the FX market affects, and is affected by, the long term and short term interest. The results show that ARIMA(3,1,2) is the best at describing the exchange rate while VAR(2) with the exchange rate and the difference between long term interests as variables gives the best predictions.

The attention deficit hyperactivity disorder (ADHD) affects about 3-5% of school-age children. In spite of many evidences of cognitive impairments in this disorder, the diagnosis is still predominantly clinical. Many relevant neuropsychological abilities have been implicated in ADHD, including deficits in executive functions (EF) of the regulatory state and delay aversion. However, it remains unclear if these three factors are independent pathways for explanation of ADHD, or even how to derive the relationships between such factors and ADHD. In addition to the investigation of the aforementioned subjects, it is necessary to explore the functional implications of symptoms and neuropsychological deficits in ADHD, to establish appropriate interventions for the disorder. Furthermore, in Brazil there are no studies that have sought to develop valid and accurate measures for evaluating state regulation and delay aversion in children, as well as ecological measures of EF. The objectives of this project are to translate, adapt and develop tools for evaluation of children and adolescents with ADHD; examine the neuropsychological performance in terms of different aspects of EF, regulation and delay aversion; and to investigate the relationship between symptoms, neuropsychological performance, and academic skills. Based on these relationships, three studies were conducted: Study 1 - Translate, adapt and seek evidence of validity and accuracy of Chexi while ecological measure of FE; Task of Regulation, as a measure of state regulation; and the Delay Aversion (TAD) test for assessment of aversion to delay. Participants 408 children, ages 4 to 7 years of Child Education students and first year of elementary school of public schools in São Paulo, as well as their teachers and parents. Study 2 - Develop a new task aversion to delay another state regulation and an inventory covering different facets of FE, to be answered by parents and teachers. Participated in a total of 332 children and adolescents between 5 and 14 years of age, of both sexes, students from 1st to 9th grade at a public school and two private schools in São Paulo. Study 3 - verify the heterogeneity of ADHD, both in terms of neuropsychological performance as compared to academic and behavioral performance in 62 children and adolescents (50% diagnosed with ADHD and 50% matched controls in terms of age, sex and education) between 7 and 14 years of age, of both sexes, students from public and private schools. Results: Study 1: Internal consistency of Chexi were excellent (Cronbach's alpha of 0.94 and 0.98 for the father answered by teachers; Spearman-Brown coefficient was 0.92 and 0.96 for parents and teachers , respectively). Exploratory factor analysis (EFA) revealed two factors for CHEXI (an EF general factor and a factor representing self-regulation and inhibitory control). Thus, the CHEXI factorial structure did not found the structured we desired. Thus, we performed a Study 2: All the three new developed measures achieved excellent internal consistency indices and EFA for IFERI yielded the five desired dimensions (working memory, cognitive flexibility, inhibitory control, delay aversion and state regulation). Study 3: Mann-Whitney Analyzes revealed differences between clinical and control groups in most of the measures and Spearman correlation analysis indicated the relationship between neuropsychological, functional, symptomatic and functional performance, highlighting the importance of the characterization of ADHD under dimensional point of view.
O TDAH é um distúrbio que atinge de 3 a 5% de crianças em idade escolar. Apesar de evidências de comprometimento cognitivo em tal transtorno, seu diagnóstico ainda é predominantemente clínico. Importantes processos neuropsicológicos têm sido implicados no TDAH, incluindo déficits de funções executivas (FE), de regulação do estado e aversão à demora. No entanto, ainda não foi esclarecido se estes três fatores constituem vias independentes para explicação do TDAH ou, ainda, como se estabelece a relação entre tais fatores e o TDAH. Além da investigação de tais relações, se faz necessário verificar quais são as implicações funcionais da presença dos sintomas e dos déficits neuropsicológicos, visto que intervenções adequadas podem ser convenientemente conduzidas. Contudo, não há no Brasil estudos que buscaram desenvolver instrumentos válidos e precisos com o objetivo de avaliar regulação do estado e aversão à demora em crianças, bem como medidas mais ecológicas de FE. Os objetivos do presente projeto são traduzir, adaptar e desenvolver instrumentos para avaliação de crianças e adolescentes com TDAH; analisar o perfil neuropsicológico em termos de funções executivas, regulação e aversão à demora; bem como investigar a relação entre o transtorno, o perfil neuropsicológico, a sintomatologia, o desempenho acadêmico e o desempenho comportamental. Para tanto, o presente projeto foi desenvolvido por meio de três estudos: Estudo 1 Traduzir, adaptar e buscar evidências de validade e precisão do CHEXI, enquanto medida ecológica de FE; da Tarefa de Regulação, como medida de regulação do estado; e do Teste de Aversão à Demora (TAD), para avaliação de aversão à demora. Participaram 408 crianças, dos 4 aos 7 anos, estudantes do Ensino Infantil e primeiro ano do Ensino Fundamental de escolas municipais da Grande São Paulo, bem como seus professores e pais. Estudo 2 desenvolver uma nova tarefa de aversão à demora, outra de regulação do estado e um inventário que abrangesse diferentes facetas de FE (IFERI), para serem respondidas pelos pais e professores. Participaram um total de 332 crianças e adolescentes, entre 5 e 14 anos de idade, de ambos os sexos, estudantes do 1º ao 9º ano de uma escola pública e duas escolas particulares de São Paulo. Estudo 3 - verificar a heterogeneidade do TDAH, tanto em termos de desempenho neuropsicológico quanto em relação a desempenho acadêmico e comportamental, em 62 crianças e adolescentes (50% com diagnóstico de TDAH e 50% controles pareados em termos de idade, sexo e escolaridade), entre 7 e 14 anos de idade, de ambos os sexos, estudantes de escolas públicas e particulares. Resultados do estudo 1:Os índices de consistência interna da CHEXI foram excelentes (alfa de Cronbach de 0,94 respondidos pelo pai e 0,98 pelos professores; coeficiente de Spearman-Brown foi de 0,92 e 0,96 para pais e professores, respectivamente). A análise fatorial exploratória revelou dois fatores para a CHEXI (fator geral para FE e outro representando autorregulação e controle inibitório). Assim, a validade fatorial não foi a inicialmente almejada. Deste modo, realizou-se um Estudo 2: todas as três novas medidas alcançaram excelentes índices consistência interna e a análise fatorial exploratória da IFERI revelou as cinco dimensões desejadas (memória de trabalho, flexibilidade cognitiva, controle inibitório, aversão à demora e regulação do estado). Resultados do estudo 3: Análises U de Mann- Whitney revelaram diferenças entre os grupos clínico e controle na maior parte da medidas e Análises de Correlação de Spearman indicaram relação entre o desempenho neuropsicológico, funcional, sintomatológico e funcional, evidenciando a importância da caracterização do TDAH sob ponto de vista dimensional.
