Full textAbstract:
O turismo étnico é, hoje, uma das áreas potenciais para o desenvolvimento daatividade turística nacional, quando o histórico interesse de negros norteamericanos pelo Brasil amplia-se via massificação do produto turístico de recorte
identitário. Esta dissertação é o resultado da pesquisa realizada com turistas negros norte-americanos no Rio de Janeiro, que aponta para a forma com que estes turistas, enquanto consumidores, influenciam na reorganização do mercado turístico carioca por meio de demandas racializadas. Curiosamente, por trás de tais demandas desvelou-se um fundo político, marcado por papéis de gênero, que fornece instrumentos para o mapeamento inicial do turismo sexual envolvendo aquela população na Cidade Maravilhosa. A pesquisa aponta que este universo está basicamente dividido em dois grupos de turistas: o do turismo étnico, majoritariamente formado por mulheres; e o do turismo sexual, composto, com
raras exceções, inteiramente por homens. Esta diferença sugere que a racialização imposta no turismo étnico seja uma exigência das mulheres americanas e indica a preocupação delas em estabelecer identidades e constatar diferenças com os
negros em lugares onde eles tenham participado da história, preocupação que não atinge os turistas sexuais".The ethnic tourism is one of the potential areas for the development of the national tourist activity nowadays in Brazil, since the historic interest of African-Americans widens through the popularization of an ethnic tourist product. This dissertation is the result of a research, made with African-American tourists in Rio de Janeiro, which shows the way, as consumers and through racial demands, they manage to influence the configuration of the cariocas tourist market. Curiously, behind those demands was a political background, oriented by gender roles, which helps to visualize the dynamic of the sexual tourism involving that population in the Wonderful City. It shows that the African-American tourist universe in Rio is basically divided into two groups: the ethnic one, which is mainly formed by women and, the sexual one, only formed by men. Such a difference suggests that the racial demands imposed by the ethnic tourism may be gender oriented, which indicates the African-American women preoccupation in establishing identities and finding out the differences about places where blacks may have taken part of the local history, which has nothing to do with the concerns of the sexual tourists.

The antiracist pedagogical practices at Childhood Education are the problem-theme of this doctoral thesis. Its aim is to analyze the elements which guide such practices in a Municipal Center of Childhood Education (CMEI) in Recife and its influence in the construction of the children and blacks’ racial identity. This research is based on the child perspective as a unique subject. It is founded on the assumption that Education in/for the Human Rights, which absorbs from the Childhood Education the right to the difference in terms of interculturality, has contributed to the children and the black ones to positively construct their racial identity. Referenced by these theoretical aspects of analysis, the research tried to answer the following questions: which educational practices are being developed by the CMEI staff, which is committed to an antiracist education? Which are the underlying elements to these practices? How are the children in these groups developing their racial identity? For this reason, we used the premises of the qualitative research and the case study, since we desired to share with the people and the place of the research guided by the unveiling of the power relations and the implicit domination to the issues of the ethnic-racial relations. The subjects of the research were: the manager, the coordinator, a teacher, two childhood development auxiliaries and twenty children from group IV. The semi-structured interview and cartoon books about racial conflicts were used as instruments for the adults. With the children, there were interviews with strategies about the self-portrait, followed by the self-identification, storytelling with black characters, male and female ones, and the modeling of princes and princesses. The analyses have showed that the practices developed at CMEI assume the incorporation of the other as genuinely the other. Thus, it could mean a perspective established in an Education in/for the Human Rights. But the implementation of an antiracist education is not easy to happen in a peaceful and consensual way, since not the whole staff and community understand the importance of this discussion. Nevertheless, part of the CMEI school staff develops the pedagogical work using this topic. This commitment with the reeducation of the ethnic-racial relations has contributed to the children to notice the differences as something positive and to some of these children and black ones to recognize themselves as black and be proud of that. Thus, we emphasize a gender component which underlies the ethnic-racial relations at CMEI: the strategies of positive statement of being a child and a black one are more centered in the girls. While they are encouraged to appreciate their body and their hair, through the care and education dimensions of the stories presented on the childhood literature books, for the boys these strategies have been minimally proposed. For the boy and the black one, there is little visibility and care. For them, there is the wish to change their color/race. Finally, we observe that the children use in their racial self-identification elements that are close to the categories used by the adults, therefore methodologies may be thought so that they are considered as subjects able to name their color/race in official researches.
As práticas pedagógicas antirracistas na Educação Infantil constituem-se no tema-problema desta tese, cujo objetivo é analisar os elementos que norteiam tais práticas em um Centro Municipal de Educação Infantil (CMEI) da rede do Recife e a sua influência na construção da identidade racial das crianças e negras. Esta pesquisa se ancora na perspectiva da criança como sujeito singular. Baseia-se no pressuposto de que uma Educação pautada em/para os Direitos Humanos, que incorpora desde a Educação Infantil, o direito à diferença na perspectiva da interculturalidade, tem contribuído para que as crianças e negras construam positivamente sua identidade racial. Referenciada por estes marcos teóricos de análise, a pesquisa buscou responder às seguintes indagações: quais práticas educativas estão sendo desenvolvidas pela equipe do CMEI, que é comprometida com uma educação antirracista? Que elementos estão subjacentes a essas práticas? Como as crianças dessas turmas estão elaborando a sua identidade racial? Para tal, recorremos aos pressupostos da pesquisa qualitativa e ao estudo de caso, pois buscávamos uma partilha com as pessoas e o local da pesquisa orientada pelo desvelamento das relações de poder e da dominação implícita às questões das relações étnico-raciais. Os sujeitos da pesquisa foram: a gestora, a coordenadora, uma professora, duas auxiliares de desenvolvimento infantil e vinte crianças da turma do Grupo IV. Utilizamos como instrumentos com os adultos: a entrevista semiestruturada e histórias em quadrinhos que traziam conflitos raciais. Com as crianças, foram realizadas entrevistas mediante estratégias do autorretrato, seguido de autoidentificação, contação de histórias com personagens negros/as e modelagem de príncipes e princesas. As análises evidenciaram que as práticas desenvolvidas no CMEI partem do princípio da incorporação do outro como verdadeiramente outro. Logo, uma perspectiva fundada na Educação em/para os Direitos Humanos. Mas a implementação de uma educação antirracista está longe de acontecer de forma tranquila e consensual, pois nem toda a equipe e comunidade compreendem a importância dessa discussão. Entretanto, parte da equipe escolar do CMEI assume e desenvolve o trabalho pedagógico com essa temática. Esse compromisso com a reeducação das relações étnico-raciais tem contribuído para que as crianças percebam as diferenças como algo positivo e para que algumas dessas crianças e negras ao reconhecerem-se como tal, orgulhem-se disso. Assim, evidenciamos um componente de gênero perpassando as relações étnico-raciais no CMEI: as estratégias de afirmação positiva do ser criança e negra estão mais centradas nas meninas. Enquanto elas são incentivadas através das dimensões do cuidar e do educar das histórias apresentadas nos livros de literatura infantil a valorizar o seu corpo e o seu cabelo, para os meninos essas estratégias foram minimamente propostas. Para o corpo do menino e negro, pouca visibilidade e cuidados. Neles, há o desejo de mudar a sua cor/raça. Por fim, reconhecemos que as crianças utilizam na sua autoidentificação racial elementos que se aproximam bastante das categorias utilizadas pelos adultos, podendo, assim, serem pensadas metodologias que as considerem como sujeitos capazes de nomearem sua cor/raça nas pesquisas oficiais.

Las cepas de BNP fueron aisladas desde muestras tomadas de bolsas periodontales (mayores a 4 mm) de pacientes con enfermedad periodontal atendidos en la Facultad de Odontología de la UNMSM. El extracto de hoja de coca fue obtenido de la Empresa Nacional de la Coca (ENACO). Los resultados de la primera prueba indicaron sensibilidad nula (-) para la mayor parte de las concentraciones evaluadas, y sensibilidad límite (sensibilidad: +) para las concentración de 12,5 % y 100 %. Los resultados del segundo estudio determinaron una concentración mínima del extracto capaz de inhibir el crecimiento de dicha bacteria, 100 % (CMI), y a las concentraciones de 12,5 % y 6,25 % se observa una repotenciación del efecto antibacteriano del extracto. Por lo tanto se concluye, que el extracto de hoja de coca, sí presenta una actividad antibacteriana frente a BNP, a las concentraciones de 100% y 12, 5%. PALABRAS CLAVE: Extracto, coca, antibacteriano, bacterias anaerobias.--- The aim of this study was to determine the antibacterial activity of the extract of coca leaves (Erythroxylum coca), on Black Pigmented Bacteria (BNP). Those periodontopathogenic bacterias are Gram negative and strict anaerobic, also they are strongly related with the progression of periodontitis. To this purpose, the study used two different kinds of tests; the first, Agar Diffusion Test; and the second, Dilution Test in Liquid Medium. BNP strains were isolated from samples taken from periodontal pockets (greater than 4 mm) of patients with periodontal disease treated at the Faculty of Dentistry of San Marcos University. The coca leaf extract was obtained from the National Coca Company (ENACO). The results of the first study indicated that the extract of Erythroxylum coca has zero sensitivity (-) for most of the tested concentrations, and sensitivity limit (sensitivity: +) to the concentration of 12,5 % and 100 %. The results of the second study determined a minimum concentration of extract able to inhibit the growth of said bacterium; this value was 100% (CMI) Also, concentrations of 12,5 % and 6,25 %, both indicated repowering of the antibacterial effect of the extract. Therefore it is concluded that, the extract of coca leaf has an antibacterial activity against BNP, in concentrations of 100% and 12, 5%. KEY WORDS: Extract, coca, antibacterial, anaerobic bacteria.

Full textAbstract:
Le glioblastome multiforme (GBM) est une tumeur de grade IV représentant 49% de toutes les tumeurs cérébrales. Malgré des modalités de traitement agressives (radiothérapie, chimiothérapie et résection chirurgicale), le pronostic est mauvais avec une survie globale médiane de 12 à 14 mois. Les aractéristiques issues de la neuro imagerie des GBM peuvent fournir de nouvelles opportunités pour la classification, le pronostic et le développement de nouvelles thérapies ciblées pour faire progresser la pratique clinique. Cette thèse se concentre sur le développement de modèles pronostiques exploitant des caractéristiques de radiomique extraites des images multimodales IRM (T1 pré- et post-contraste, T2 et FLAIR). Le contexte méthodologique proposé consiste à i) recaler tous les volumes multimodaux IRM disponibles et en segmenter un volume tumoral unique, ii) extraire des caractéristiques radiomiques et iii) construire et valider les modèles pronostiques par l’utilisation d’algorithmes d’apprentissage automatique exploitant des cohortes cliniques multicentriques de patients. Le coeur des méthodes développées est fondé sur l’extraction de radiomiques (incluant des paramètres d’intensité, de forme et de textures) pour construire des modèles pronostiques à l’aide de deux algorithmes d’apprentissage, les machines à vecteurs de support (support vector machines, SVM) et les forêts aléatoires (random forest, RF), comparées dans leur capacité à sélectionner et combiner les caractéristiques optimales. Les bénéfices et l’impact de plusieurs étapes de pré-traitement des images IRM (re-échantillonnage spatial des voxels, normalisation, segmentation et discrétisation des intensités) pour une extraction de métriques fiables ont été évalués. De plus les caractéristiques radiomiques ont été standardisées en participant à l’initiative internationale de standardisation multicentrique des radiomiques. La précision obtenue sur le jeu de test indépendant avec les deux algorithmes d’apprentissage SVM et RF, en fonction des modalités utilisées et du nombre de caractéristiques combinées atteignait 77 à 83% en exploitant toutes les radiomiques disponibles sans prendre en compte leur fiabilité intrinsèque, et 77 à 87% en n’utilisant que les métriques identifiées comme fiables.Dans cette thèse, un contexte méthodologique a été proposé, développé et validé, qui permet la construction de modèles pronostiques dans le cadre des GBM et de l’imagerie multimodale IRM exploitée par des algorithmes d’apprentissage automatique. Les travaux futurs pourront s’intéresser à l’ajout à ces modèles des informations contextuelles et génétiques. D’un point de vue algorithmique, l’exploitation de nouvelles techniques d’apprentissage profond est aussi prometteuseGlioblastoma multiforme (GBM) is a WHO grade IV tumor that represents 49% of ail brain tumours. Despite aggressive treatment modalities (radiotherapy, chemotherapy and surgical resections) the prognosis is poor, as médian overall survival (OS) is 12-14 months. GBM’s neuroimaging (non-invasive) features can provide opportunities for subclassification, prognostication, and the development of targeted therapies that could advance the clinical practice. This thesis focuses on developing a prognostic model based on multimodal MRI-derived (Tl pre- and post-contrast, T2 and FLAIR) radiomics in GBM. The proposed methodological framework consists in i) registering the available 3D multimodal MR images andsegmenting the tumor volume, ii) extracting radiomics iii) building and validating a prognostic model using machine learning algorithms applied to multicentric clinical cohorts of patients. The core component of the framework rely on extracting radiomics (including intensity, shape and textural metrics) and building prognostic models using two different machine learning algorithms (Support Vector Machine (SVM) and Random Forest (RF)) that were compared by selecting, ranking and combining optimal features. The potential benefits and respective impact of several MRI pre-processing steps (spatial resampling of the voxels, intensities quantization and normalization, segmentation) for reliable extraction of radiomics was thoroughly assessed. Moreover, the standardization of the radiomics features among methodological teams was done by contributing to “Multicentre Initiative for Standardisation of Radiomics”. The accuracy obtained on the independent test dataset using SVM and RF reached upto 83%- 77% when combining ail available features and upto 87%-77% when using only reliable features previously identified as robust, depending on number of features and modality. In this thesis, I developed a framework for developing a compréhensive prognostic model for patients with GBM from multimodal MRI-derived “radiomics and machine learning”. The future work will consists in building a unified prognostic model exploiting other contextual data such as genomics. In case of new algorithm development we look forward to develop the Ensemble models and deep learning-based techniques

La tesi tracta, des del punt de vista de l’anàlisi de dades, la possibilitat de detecció directa d’ones gravitatòries emeses per sistemes binaris d’objectes compactes de massa similar: forats negres, estels de neutrons, nanes blanques. En els capítols introductoris,
a) es dóna una descripció detallada i exhaustiva de com passar dels patrons d’ona teòrics a la senyal detectada;
b) s’introdueixen les eines més emprades en l’anàlisi de dades d’ones gravitatòries, amb especial menció a la discussió sobre les amplituds efectiva i característica.
A més, els resultats originals de la tesi segueixen tres línies de recerca diferents:
1) S’ha predit la precisió amb la que el futur detector interferomètric espacial LISA, estimarà els paràmetres (posició, masses, velocitat de rotació, paràmetres cosmològics…) de les observacions de xocs entre dos forats negres supermassius en la fase “inspiral”.
2) S’ha desenvolupat un algorisme propi de cerca de senyals gravitatòries procedents de sistemes binaris estel•lars, basat en teories de probabilitat Bayesiana i MCMC. Aquest algorisme distingeix alhora milers de senyals superposades en una única sèrie temporal de dades, extraient paràmetres individuals de cadascuna d’elles.

In this PhD thesis one studies, from the data analysis perspective, the possibility of direct detection of gravitational waves emitted by similar mass compact binary objects: black holes, neutron stars, white dwarfs. In the introductory chapters, a) a detailed and exhaustive description about how to derive the detected strain from the theoretical emitted waveform predictions is given; b) the most used gravitational wave data analysis results are derived, being worth pointing out the discussion about effective and characteristic amplitudes. Moreover, three different research lines have been followed in the thesis: 1) It has been predicted the parameter estimation (position, masses, spin, cosmological parameters…) of supermassive black hole binary inspiral signals, observed with the future interferometric space detector, LISA. 2) A new algorithm, based on Bayesian probability and MCMC techniques, has been developed in order to search for gravitational wave signals from stellar-mass binary systems. The algorithm is able to distinguish thousands of overlapping signals from a single observed time series, allowing for individual parameter extraction. 3) It has been, mathematically and rigorously, defined how to compute the validity range (for parameter estimation and detection purposes) of approximated gravitational waveform models, applying it to the particular case of closed-form models

Previous issue date: 2009-04-15This research analyzed the development and the introduction of a quota program for black people on the quota politics in its first years of implementation at the State University of Ponta Grossa (UEPG). The research sought to describe the representations that the students from the quotas 1 (universal) and 3 (black people) have regarding to the quotas for black ones as well as to analyze the relationship that the quota black students have established in their social and academic life environment as with the professors as with their classmates in the University Course. The theoretical discussions were supported in such authors: Rüsen (1987 and 2006), Freire (1982, 1986, 1996), Cerri (2001) and Pacievitch (2007), Skliar and Dushatzky (2001), Rios (2005) and Silva and Silvério (2003), Henriques (2004), Chauí (2001), Siss (2003), Neves (2005), Carvalho (2004), Brandão (2005), Gomes (2001), Sá (1996) and Spink (1995). The basis methodology is the qualitative research since we emphasized the process in witch this politic was implemented. In the beginning of the process we used the qualitative research, which gave the research context, and we explored some graphics and charts with the students marks obtained in the 2006 and 2007 vestibulares (the University admission exam). We calculated the marks by quotas and the pattern diversion of each course relating to the quotas 3 and 1. We selected some courses from the UEPG in order to work with a sample. Then, we went to the qualitative research, in which the Historical Conscious was the base for the instruments elaboration, and the Social Representations Theory for analyze. Firstly we applied a questionnaire for all the students from the selected courses, following the analyses and the categorization of the questionnaires, and then we applied new questionnaires and interviews only for the quote black people from the same selected courses. We sought to look at the specific positive and negative effects of this politics instead of the pure product. The results allowed us to reveal that the quotas have helped the increase of the black and the public school students’ population at the university in 15%; witch percentage could be smaller without such quotas politic. Most of the students from UEPG are not aware about the affirmative politics and make their opinion about the black quotas based on their common sense. They associate the small quantity of black people at the university to the poor quality of the public teaching. The black students with quotas felt under discrimination into the course including by some professors that made their quota rejection clear. The different positions about the quotas can be considered by the Social Representations like old social representations of the black people in the society witch get in confront with the new representations that have been built by those that fight for the black people rights. Based in the questionnaires applied in the six courses of the UEPG and the questionnaires and the interview with the black people quotas was possible to construct the diagrams that referred to the students’ representations on the UEPG quotas. Thus, it is necessary to bear in mind that the acquisition of a Higher Education degree is not enough for eliminating the social and racial differences. The vacancies for the black population into the University program are not enough; in fact, the changing in the admission is just one aspect within a major process.
Esta pesquisa analisou o desempenho, a inserção e as representações dos cotistas negros sobre a política de cotas nos seus primeiros anos no curso na Universidade Estadual de Ponta Grossa. A pesquisa buscou; descrever as representações que os alunos das cotas 1 (universal) e 3 (negros) apresentam em relação às cotas para negros, bem como analisar as relações que os cotistas negros estabelecem no cotidiano social e acadêmico tanto com os professores quanto com os colegas do curso em que frequentam. Os autores que sustentaram as discussões teóricas foram: Rüsen (1987 e 2006), Freire (1982, 1986, 1996), Cerri (2001) e Pacievitch (2007), Skliar e Dushatzky (2001), Rios (2005) e Silva e Silvério (2003), Henriques (2004), Chauí (2001), Siss (2003), Neves (2005), Carvalho (2004), Brandão (2005), Gomes (2001), Sá (1996) e Spink (1995). A base metodológica é a pesquisa qualitativa, pois demos mais ênfase ao processo de como essa política foi implementada. Para tanto utilizamos inicialmente a pesquisa quantitativa, que compôs o cenário da pesquisa, empregamos o uso de gráficos e tabelas com as notas dos alunos nos vestibulares 2006 e 2007, calculamos as médias por cotas e o desvio padrão de cada curso com relação à cota 3 e à cota 1. Selecionamos alguns cursos da UEPG, para que pudéssemos trabalhar com uma amostragem. Em seguida, partimos para a pesquisa qualitativa, na qual a teoria da Consciência Histórica serviu como base para elaboração dos instrumentos, e a teoria das Representações Sociais para análise. Primeiramente aplicamos questionários para todos os alunos dos cursos selecionados. posteriormente a análise e categorização dos questionários, aplicamos novos questionários e entrevistas somente para os cotistas negros destes mesmos cursos selecionados. Procuramos voltar um olhar mais específico aos efeitos, tanto positivos quanto negativos dessa política do que simplesmente ao produto. Os resultados alcançados por meio desta pesquisa permitiram revelar que as cotas possibilitaram o aumento do acesso da população de alunos negros e de escola pública em 15% na universidade, porcentagem que seria menor caso essa política não existisse. Os alunos da UEPG em geral desconhecem as políticas afirmativas e falam sobre as cotas para negros baseado no senso comum. A grande maioria associa a pequena quantidade de negros na universidade à má qualidade do ensino público. Os alunos cotistas negros sentem discriminação no curso, inclusive por parte de alguns professores, que fizeram questão de deixar explicita sua rejeição às cotas. As diferentes posições sobre as cotas podem ser consideradas por meio das Representações Sociais, como antigas representações sociais dos negros na sociedade que chocam-se com novas representações construídas por aqueles que lutam a favor dos direitos dos negros. Tomando como base os questionários aplicados nos seis cursos da UEPG e os questionários e entrevistas com os cotistas negros, possibilitaram a construção de diagramas que referem-se as representações dos alunos sobre as cotas na UEPG. Assim, faz-se necessário ter em mente que só a aquisição do grau Superior não é condição suficiente para eliminação da desigualdade social e racial. As vagas

Esta pesquisa objetiva o desenvolvimento a respeito da possibilidade de antirracismo da branquitude – identidade racial branca – conforme as representações sociais entre negra/os e branca/os presentes nos fóruns institucionais do Movimento Negro em Salvador-BA, o meu “campo-tema”. Na primeira parte da dissertação, ou seja, nos capítulos I e II, realizo as discussões ético-políticas e teórico-metodológicas que embasam este percurso hermenêutico. Logo, valho-me do desafio de proposição a uma antropologia descolonial sobre raça; realização da “prática etnográfica politicamente engajada”; da “participação observante”; “autoetnografia”; e da técnica de entrevista qualitativa semiestruturada. Na segunda parte (capítulos III e IV) disserto, conforme a análise de discurso e da prática em campo, sobre as minhas apreensões acerca do habitus da/o “branca/o fora do lugar” e do sistema simbólico relacionado a este sujeito que se encontra entre os espaços de agenciamento do MN e propõe-se antirracista. Quanto ao arcabouço, de modo geral, elaborei uma interface entre as epistemologias do paradigma da colonialidade do poder, do corpo e do saber; estudos do campo crítico da branquitude disseminados no Brasil; e parte da genealogia do pensamento negro. Pude concluir que as representações em campo são relacionadas à circularidade entre o pensamento acadêmico e o empirista, ideologias, o censo comum e as concepções do Estado; não há consenso quanto a possibilidade de alianças entre branca/os e o MN, nem mesmo na microestrutura de uma entidade, todavia não foi apreensível em Salvador qualquer organização que vete completamente a relação política com a/os mesma/os; existe sim a possibilidade de antirracismo da/os branca/os e isso é, em termos generalistas, codificado pelo MN, porém não sem ressalvas. Estas ressalvas nos levam a entender a diferença entre antirracismo e não-racismo e a impossibilidade da/o branca/o não reproduzir o racismo, portanto de não ser racista em tempos de “sistema-mundo / patriarcal / capitalista / colonial /moderno".
This research aims at the development of the possibility of anti-racism of whiteness - white racial identity - as the social representations of black and white gifts in institutional forums of the Black Movement in Salvador, Bahia, my "theme-field" . In the first part of the dissertation, that is in Chapters I and II, realize the ethical-political and theoretical - methodological discussions that support this hermeneutic route. Therefore, I make use of the proposition challenge to a decolonial anthropology about race; holding of "ethnographic practice politically engaged"; the "bservant participation"; "self etnography"; and semi-structured qualitative interview technique. In the second part (Chapters III and IV) speak as discourse analysis and practice in the field, on my apprehensions about the habitus of the "White out of place" and the symbolic system related to this subject that is among the agency areas of MN and proposed anti-racist. As for the framework, in general, I prepared an interface between the epistemologies of the coloniality power paradigm, and the body, and the knowledge; studies of the critical field of disseminated whiteness in Brazil; and part of the genealogy of black thought. I could conclude that the representations in the field are related to circularity between academic thinking and empiricist ideology, the common census and state conceptions; there is no consensus on the possibility of alliances between white and MN, even in the microstructure of an entity, but is not graspable in Salvador any organization to completely veto the political relationship with them; there is the possibility of anti-racism of the white them and this is, in general terms, encoded by the MN, but not without reservations. These exceptions lead us to understand the difference between anti-racism and non-racism and the impossibility of the white / non reproduce racism, so it is not racist in times of "world-system / patriarchal / capitalist / colonial / modern".

Full textAbstract:
The thesis contains four chapters which attempt to extend our understanding of mental toughness. The thesis focuses predominantly on sporting environments, which can be very stressful and often require athletes to perfonn under intense pressure; as such it provides a useful context to examine mental toughness. Using Reinforcement Sensitivity Theory (RST; McNaughton & Gray, 2000) as a theoretical framework, the thesis contains five empirical studies (organised into two chapters for the purpose of publication), which attempt to apply the principles of RST to understand how cricketers maintain or enhance their performance under pressure. The thesis is not a test of Reinforcement Sensitivity but an application of its principles in a novel environment. Chapter 1 critically reviews the research on mental toughness and highlights a number of theoretical and empirical limitations which need to be resolved. Most notably these include: (i) circuitous and somewhat confusing definitions; (ii) only modest attempts to draw upon relevant theory to inform a priori hypothesis testing; (ii i) a lack of valid measurement too ls; and (iv) limited experimental studies that focus on the development of mental toughness. The chapter finishes by proposing a neuro-cognitive explanation of mentally tough behaviour based on the tenets of the revised Reinforcement Sensitivity Theory (McNaughton & Gray. 2000). Chapter 2 contains four separate studies. The first two studies were concerned with the development of a valid, informant-rated, questionnaire to measure mental toughness. The final two studies explored the interactive relationship between rein forcement sensitivities and mental toughness. The findings of the stud ies suggested that the relationship between RST and mental toughness is a somewhat complex one in that cricketers rated as mentally tough by their coaches tended to be sensitive to punishment cues and insensitive to reward cues. In contrast, cricketers rated as low in mental toughness by their coaches tended to be sensitive to punishment cues and reward cues. These results are discussed and explained in terms of threat detection, behavioural inhibition and dec ision making accuracy. Chapter 3 depicts a quasi-experimental, longitud inal intervent ion study. The study reports on the design, delivery and evaluation ofa theoretically grounded mental tough ness training program for youth aged Academy cricketers. The intervention was designed to expose cricketers to punishment conditioned stimuli in the training environment and to equip them with effective coping skills to manage threat. The results are discussed in terms of the theoretical and applied implications of using punishment to alter behaviour. Chapter 4 concludes the thesis. More specificall y, the chapter provides a summary and integrated discussion of the thesis findings, implications from both theoretical and applied perspectives, methodological and conceptual lim itations and avenues for future research.

Full textAbstract:
The main topic of this thesis is the neuro-fuzzy control approach for mobile robot navigation in indoor environments. A system for directing the robot towards any target, point has been developed and tested in simulated environments. The autonomous mobile robot uses only information obtained from its infrared and contact sensors in order to reach the target point and to avoid collisions. The control system is organized in a top-bottom hierarchy of various tasks to be executed by the robot, tasks which correspond to specific robot behaviors during his navigation. The task to be executed at every control cycle is determined according to the robot behavior required to be performed at that time. Each task is implemented through fuzzy (or neuro-fuzzy) techniques. When multiple low-level behaviors are required, a command fusion method is used to combine the output of several fuzzy sub-systems. A switching coordination method is used to select a behavior among higher level behaviors.

Full textAbstract:
Aim: This study aimed to develop a grounded theory to explain the experience of patients with neurodegenerative diseases and their carers, following an episode of residential respite care. Background: Neurodegenerative diseases are incurable, debilitating and result in progressive deterioration of the patient which present as problems with cognitive functioning (dementias) and/or physical functioning (ataxias). To allow quality of life and purpose for the patient and caregiver, as well as providing value for money, respite is an area of care which could offer the patient rehabilitation, maximisation of functionality and quality of life; relief from caregiving duties for the carer and signposting for additional assistance and support. Methods: This was a qualitative, grounded theory study conducted across south east England. An initial audit, attendance at support groups and specialist clinics provided scoping of the scale of the problems encountered by this patient population. Data collection included 17 semi structured interviews conducted with patients and carers who had recently received residential respite, non-participant observation at a hospice offering dedicated respite care and 4 hospice staff interviews. Findings: A successful respite depended on the patient and carer identifying the need for respite and the information required to determine where, what, when and how respite could be accessed. The logistics of the referral process, preparation for respite and the handover of care needs to professionals were key factors for a therapeutic admission. Conclusion: The outcomes from the respite admission should be mutually acceptable to both the patient and carer and be able to demonstrate acceptance and adaptation to a new normalcy, influenced by disease progression and reflecting on time present and time past. The onward journey sees a transitioning which involves restoration and building up a level of resilience for the carer, which all contribute to sustainability and being able to continue in the caring role.

Full textAbstract:
The design of effective, robust and autonomous controllers for multi-agent and multi-robot systems is a long-standing problem in the fields of computational intelligence and robotics. Whilst nature-inspired problem-solving techniques such as reinforcement learning (RL) and evolutionary algorithms (EA) are often used to adapt controllers for solving such tasks, the complexity of such tasks increases with the addition of more agents (or robots) in difficult environments. This is due to specific issues related to task complexity, such as the curse of dimensionality and bootstrapping problems. Despite an increasing attempt over the last decade to incorporate behavior (knowledge) transfer in machine learning so that relevant behavior acquired in previous learning experiences can be used to boost task performance in complex tasks, using evolutionary algorithms to facilitate behavior transfer (especially multi-agent behavior transfer) has received little attention. It remains unclear how behavior transfer addresses issues such as the bootstrapping problem in complex multi-agent tasks (for example, RoboCup soccer). This thesis seeks to investigate and establish the essential features constituting effective and efficient evolutionary search to augment behavior transfer for boosting the quality of evolved behaviors across increasingly complex tasks. Experimental results indicate a hybrid of objective-based search and behavioral diversity maintenance in evolutionary controller design coupled with behavior transfer yields evolved behaviors of significantly high quality across increasingly complex multi-agent tasks. The evolutionary controller design method thus addresses the bootstrapping task for the given range of multi-agent tasks, whilst comparative controller design methods yield scant performance results.

Full textAbstract:
Publicación a texto completo no autorizada por el autorEstudia la actividad fotocatalítica de nanopartículas de TiO2 soportadas en una película de alcohol polivinílico en la degradación del colorante negro reactivo 5 (NR5). Una dispersión de nanopartículas de TiO2 (soles de TiO2) es preparada empleando como precursor tetraisopropóxido de titanio a pH 1. Luego el sol de TiO2 se mezcla con una solución de alcohol polivinílico (PVA) y glutaraldehído a pH 1, finalmente la dispersión resultante es secada al ambiente obteniendo nanopartículas de TiO2 soportadas en una película de alcohol polivinílico (película de TiO2-PVA) con una concentración de 4,4.10-4 mol.Ti/g de película. La actividad fotocatalítica de los soles de TiO2 así como de las películas de TiO2-PVA son probadas en un sistema de degradación de color compuesto principalmente por una fuente de radiación UV-VIS, que decolora (degrada) una solución de colorante NR5 hasta completamente incoloro. El desarrollo del proceso de fotodegradación es evaluado con un espectrofotómetro UV-VIS a 600 nm. También se evalúa el efecto de las siguientes variables en el proceso de fotodegradación: la concentración del sol de TiO2, concentración del colorante, y el pH. Empleando un sistema de fotodegradación y 1,5 gramos de película de TiO2-PVA se logra degradar completamente 100 mL de colorante NR5 a 25 ppm en 25 minutos, así mismo estas pueden trabajar en un amplio rango de pH, siendo más eficientes a pH ácidos. Una de las desventajas de las películas de PVA-TiO2 es que al emplearlas en ciclos sucesivos de fotodegradación reducen paulatinamente su poder catalítico hasta desaparecer (envenenamiento del catalizador). Los resultados de este trabajo son comparados con trabajos similares: xerogeles de TiO2 soportados en vidrio en la fotodegradación de colorantes, y catalizadores biológicos en fotodegradación del colorante negro reactivo 5; concluyendo que las películas de TiO2-PVA preparadas en este trabajo presentan características superiores que los materiales preparados en los trabajos comparados, en la fotodegradación de la matriz colorante en solución por la velocidad a la que trabaja así como los amplios rangos de pH a los que son estables. El envenenamiento del catalizador es una desventaja en común con estos trabajos, y en general es una característica del TiO2 cuando es usado como catalizador.

As mudanças que ocorreram no campo religioso brasileiro nas últimas décadas atingiram profundamente as religiões de matriz africana — a umbanda e o candomblé. Entre estas mudanças uma guerra santa deflagrada pelos neopentecostais contra estas religiões tem sido o foco principal das análises sócio-antropológicas que se dedicam, porém, a interpretar os ataques dos neopentecostais. Esta tese tem por objetivo estudar não só as ações dos afro-brasileiros a estes ataques, mas também as demais mudanças que se realizam neste universo religioso. As articulações do movimento negro com estas religiões serão abordadas em uma perspectiva histórica que permitirá comparar as propostas, das diversas fases deste movimento social, para o candomblé e a umbanda, assim como realizar uma comparação com as propostas das federações umbandistas. Alicerçada em teorias sociológicas da ação e em teorias antropológicas contemporâneas, a pesquisa de campo foi realizada nos terreiros de umbanda e candomblé de Juiz de Fora-MG, no período de 2005 a 2008.
The changes that have taken place in the field of religion in Brazil in the last few decades have deeply affected religions of African origin — umbanda and candomble. Among these changes, a holy war waged by the neopentecostals against these religions has been the main focus of social-anthropological analyses, which, however, are aimed at interpreting these attacks by the neopentecostals. The aim of this thesis is to study not only the reaction of the Afro-Brazilian actors to these attacks, but also the other changes they are carrying out in this religious universe. The articulations of the black movement with these religions will be covered in a historical perspective which will allow us to compare the proposals of the different phases of this social movement for Candomble and Umbanda, as well as with the proposals of the federations. Based on sociological theories of action and on contemporary anthropological theories, the field research was carried out in the Umbanda and Candomble centres in Juiz de Fora, in the State of Minas Gerais, from 2005 to 2008.

¿Por qué el testimonio del afroperuano ha sido descuidado durante tanto tiempo? La respuesta puede ser obvia, se trata de la voz y la historia del otro, el llamado subalterno, que no es escuchado ni visible para los sectores hegemónicos que detentan el poder político y económico en la sociedadperuana. Cierto es que se ignora este corpus por completo hasta el día de hoy. El objetivo de esta tesis es visibilizar el corpus del testimonio afroperuano, para incluirlo como un tema a ser debatido y estudiado con mayor ahínco en nuestro contexto posteriormente. La presente tesis doctoral se centra en el análisis de aquellos textos que recogen la voz del sujeto afroperuano y permiten conocer su cultura. Se trata de un corpus producido entre 1974 y 2018. La investigación sobre este campo de estudio ha sido emprendida por especialistas de las ciencias sociales y de las ciencias humanas, pero aún sigue siendo una exigencia de los actuales estudios literarios afrontar el reto de un corpus que genera tanta polémica en la sociedad. En el análisis de los testimonios se comprueba la riqueza discursiva de la oralidad. En buena parte la gran expresividad del discurso popular se logra debido a que este es original, carnavalesco y hasta desbordante. Existen varios planteamientos respecto a la definición y problemática que ha suscitado el testimonio en América Latina.Tesis

Full textAbstract:
In Is Spirituality an Intelligence? Motivation, Cognition, and the concern of Psychology of Ultimate Concern, Robert Emmons develops a case for spirituality as a form of intelligence. His thesis claims that spiritual intelligence is a “set of capacities and abilities that enable people to solve problems and attain goals in their everyday lives”: “the capacity for transcendence; the ability to enter into heightened spiritual states of consciousness; the ability to invest everyday activities, events, and relationships with a sense of the sacred; the ability to utilize spiritual resources to solve problems in living; and the capacity to engage in virtuous behavior. I use spiritual intelligence and these frameworks throughout to address these common themes within the Black community beginning in the Second Great Awakening.
I use these five components to illuminate the rise of the revolutionary streams of Spiritual Intelligence within unique works of two Black activists: David Walker and Maria Stewart. I then contextualize these developments in the experiences of my family and my own experiences as a Black activist. I argue for the recognition of religious thinking and illustrate the structural embodiment of this form of spiritual intelligence through multiple generations of Black Activism. I argue that Spiritual Intelligence is one way this particular community fights adversity in greater America society. In valuing religion through understanding these actions of resistance black activism is realized in the larger epistemic landscape. Particularly arguing against the secularization of resistance and activism.

Full textAbstract:
The subject of this thesis is to develop a temporal neuro-fuzzy system for fore-
casting the future behavior of a multivariate time series data.
The system has two components combined by means of a system interface.
First, a rule extraction method is designed which is named Fuzzy MAR (Multivari-
ate Auto-regression). The method produces the temporal relationships between
each of the variables and past values of all variables in the multivariate time series
system in the form of fuzzy rules. These rules may constitute the rule-base in a
fuzzy expert system.
Second, a temporal neuro-fuzzy system which is named ANFIS unfolded in -
time is designed in order to make the use of fuzzy rules, to provide an environment
that keeps temporal relationships between the variables and to forecast the future
behavior of data. The rule base of ANFIS unfolded in time contains temporal
TSK(Takagi-Sugeno-Kang) fuzzy rules. In the training phase, Back-propagation
learning algorithm is used. The system takes the multivariate data and the num-
ber of lags needed which are the output of Fuzzy MAR in order to describe a
variable and predicts the future behavior.
Computer simulations are performed by using synthetic and real multivariate
data and a benchmark problem (Gas Furnace Data) used in comparing neuro-
fuzzy systems. The tests are performed in order to show how the system efficiently
model and forecast the multivariate temporal data. Experimental results show
that the proposed model achieves online learning and prediction on temporal data.
The results are compared by other neuro-fuzzy systems, specifically ANFIS.

In this study the utilization of neuro-fuzzy techniques is investigated for the
realisation of intelligent control. Neuro-fuzzy systems combine the learning capabilities of neural
networks with the rule based system description offered by fuzzy logic.
Techniques are evaluated by means of a simple two-dimensional simulation of a three-segment
robotic manipulator. The inverse kinematics and path planning required in such a system
provides all the complexity needed for testing and evaluation.
In complex systems, obtaining sufficient training examples also prove to be a problem. To
address this problem an automated process of 'action evolution' was implemented, through
which a genetic algorithm is used to collect examples as training data.
A generic modular controller architecture is developed in order to simplify the comparison of
different neural and neuro-fuzzy controllers. This architecture unifies numerous controller
architectures into a single controller, capable of representing and combining classical, adaptive,
intelligent and reinforcement learning controllers and it exposes the presence of various
cognitive attributes.
Neural and neuro-fuzzy systems are implemented and evaluated for local trajectory tracking and
for global path planning. A serious problem of contradicting solutions encountered in the
examples produced by the genetic algorithm, is solved through reinforcement learning. A
modified fuzzy clustering algorithm is used to estimate the system's state values and control
commands are derived by optimising this value. Modifications included negative reinforcement
of prohibited states and concepts borrowed from ant algorithms for establishing solution paths.
This study highlights the effect of ill-posed problems on the training of intelligent controllers. It
shows how the problem can be simplified by basing the control policy on a value function and it
implements neuro-fuzzy techniques to rapidly construct such a function. Proposals are made on
how memory based search algorithms can be used to improve training data integrity and how
evolving self-organising maps might prevent erroneous policy interpolation.
This study contributes valuable conclusions on the implementation of intelligent controllers for
the control of complex non-linear systems.Thesis (M.Ing. (Electrical and Electronic Engineering))--North-West University, Potchefstroom Campus, 2006.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOEsta dissertação apresenta a proposta e o desenvolvimento de um sistema de mineração de dados inteiramente automático. O objetivo principal é criar um sistema que seja capaz de realizar a extração de informações obscuras a partir de bases de dados complexas, sem exigir a presença de um especialista técnico para configurá-lo. O sistema híbrido neuro-fuzzy hierárquico com particionamento binário (NFHB) vem apresentando excelentes resultados em tarefas de classificação de padrões e previsão, além de possuir importantes características não encontradas em outros sistemas similares, entre elas: aprendizado automático de sua estrutura; capacidade de receber um número maior de entradas abrangendo um maior número de aplicações; e geração de regras lingüísticas como produto de seu treinamento. Entretanto, este modelo ainda necessita de uma complexa parametrização inicial antes de seu treinamento, impedindo que o processo seja automático em sua totalidade. O novo modelo proposto busca otimizar a parametrização do sistema NFHB utilizando a técnica de coevolução genética, criando assim um novo sistema de mineração de dados completamente automático. O trabalho foi realizado em quatro partes principais: avaliação de sistemas existentes utilizados na mineração de dados; estudo do sistema NFHB e a determinação de seus principais parâmetros; desenvolvimento do sistema híbrido neuro-fuzzy-genético automático para mineração de dados; e o estudo de casos. No estudo dos sistemas existentes para mineração de dados buscou-se encontrar algum modelo que apresentasse bons resultados e ainda fosse passível de automatização. Várias técnicas foram estudadas, entre elas: Métodos Estatísticos, Árvores de Decisão, Associação de Regras, Algoritmos Genéticos, Redes Neurais Artificiais, Sistemas Fuzzy e Sistemas Neuro-Fuzzy. O sistema NFHB foi escolhido como sistema de inferência e extração de regras para a realização da mineração de dados. Deste modo, este modelo foi estudado e seus parâmetros mais importantes foram determinados. Além disso, técnicas de seleção de variáveis de entradas foram investigadas para servirem como opções para o modelo. Ao final, foi obtido um conjunto de parâmetros que deve ser automaticamente determinado para a completa configuração deste sistema. Um modelo coevolutivo genético hierárquico foi criado para realizar com excelência a tarefa de otimização do sistema NFHB. Desta forma, foi modelada uma arquitetura hierárquica de Algoritmos Genéticos (AG s), onde os mesmos realizam tarefas de otimização complementares. Nesta etapa, também foram determinados os melhores operadores genéticos, a parametrização dos AG s, a melhor representação dos cromossomas e as funções de avaliação. O melhor conjunto de parâmetros encontrado é utilizado na configuração do NFHB, tornando o processo inteiramente automático. No estudo de casos, vários testes foram realizados em bases de dados reais e do tipo benchmark. Para problemas de previsão, foram utilizadas séries de carga de energia elétrica de seis empresas: Cerj, Copel, Eletropaulo, Cemig, Furnas e Light. Na área de classificação de padrões, foram utilizadas bases conhecidas de vários artigos da área como Glass Data, Wine Data, Bupa Liver Disorders e Pima Indian Diabetes. Após a realização dos testes, foi feita uma comparação com os resultados obtidos por vários algoritmos e pelo NFHB original, porém com parâmetros determinados por um especialista. Os testes mostraram que o modelo criado obteve resultados bastante satisfatórios, pois foi possível, com um processo completamente automático, obter taxas de erro semelhantes às obtidas por um especialista, e em alguns casos taxas menores. Desta forma, um usuário do sistema, sem qualquer conhecimento técnico sobre os modelos utilizados, pode utilizá-lo para realizar min
This dissertation presents the proposal and the development of a totally automatic data mining system. The main objective is to create a system that is capable of extracting obscure information from complex databases, without demanding the presence of a technical specialist to configure it. The Hierarchical Neuro-Fuzzy Binary Space Partitioning model (NFHB) has produced excellent results in pattern classification and time series forecasting tasks. Additionally, it provides important features that are not present in other similar systems, such as: automatic learning of its structure; ability to deal with a larger number of input variables, thus increasing the range of possible applications; and generation of linguistic rules as a result of its training process. However, this model depends on a complex configuration process before the training is performed, hindering to achieve a totally automatic system. The model proposed in this Dissertation tries to optimize the NFHB system parameters by using the genetic coevolution technique, thus creating a new automatic data mining system. This work consisted of four main parts: evaluation of existing systems used in data mining; study of the NFHB system and definition of its main parameters; development of the automatic hybrid neuro-fuzzy-genetic system for data mining; and case studies. In the study of existing data mining systems, the aim was to find a suitable model that could yield good results and still be automated. Several techniques have been studied, among them: Statistical methods, Decision Trees, Rules Association, Genetic Algorithms, Artificial Neural Networks, Fuzzy and Neuro- Fuzzy Systems. The NFHB System was chosen for inference and rule extraction in the data mining process. In this way, this model was carefully studied and its most important parameters were determined. Moreover, input variable selection techniques were investigated, to be used with the proposed model. Finally, a set of parameters was defined, which must be determined automatically for the complete system configuration. A hierarchical coevolutive genetic model was created to execute the system optimization task with efficiency. Therefore, a hierarchical architecture of genetic algorithms (GAs) was created, where the GAs execute complementary optimization tasks. In this stage, the best genetic operators, the GAs configuration, the chromossomes representation, and evaluation functions were also determined. The best set of parameters found was used in the NFHB configuration, making the process entirely automatic. In the case studies, various tests were performed with benchmark databases. For forecasting problems, six electric load series were used: Cerj, Copel, Eletropaulo, Cemig, Furnas and Light. In the pattern classification area, some well known databases were used, namely Glass Data, Wine Data, Bupa Liver Disorders and Pima Indian Diabetes. After the tests were carried out, a comparison was made with known models and with the original NFHB System, configured by a specialist. The tests have demonstrated that the proposed model generates satisfactory results, producing, with an automatic process, similar errors to the ones obtained with a specialist configuration, and, in some cases, even better results can be obtained. Therefore, a user without any technical knowledge of the system, can use it to perform data mining, extracting information and knowledge that can help him/her in decision taking processes, which is the final objective of a Knowledge Data Discovery process.

Engenharia Electrotécnica e de ComputadoresThe main goal of this thesis will be focused on developing an adaptative closed loop control solution, using fuzzy methodologies. A positive theoretical and experimental contribution, regarding modelling and control of fuzzy and neuro fuzzy systems, is expected to be achieved. Proposed non-linear identification solution will use for modelling and control, a recurrent neuro fuzzy architecture. Regarding model solution, a state space approach will be considered during fuzzy consequent local models design. Developed controller will be based on model parameters, being expected not only a stable closed loop solution, but also a static error with convergence towards zero. Model and controller fuzzy subspaces, will be partitioned throughout process dynamical universe, allowing fuzzy local models and controllers commutation and aggregation. With the aim of capturing process under control dynamics using a real time approach, the use of recursive optimization techniques are to be adopted. Such methods will be applied during parameter and state estimation, using a dual decoupled Kalman filter extended with unscented transformation. Two distinct processes one single-input (SISO) other multi-input (MIMO), will be used during experimentation. It is expected from experiments, a practical validation of proposed solution capabilities for control and identification. Presented work will not be completed, without first presenting a global analysis of adopted concepts and methods, describing new perspectives for future investigations.

Full textAbstract:
Recently there has been an increasing amount of research into autonomous vehicles for real-world driving. Much progress has been made in the past decade with many automotive manufacturers demonstrating real-world prototypes. Current predictions indicate that roads designed exclusively for autonomous vehicles will be constructed and thus this thesis explores the use of methods to automatically produce controllers for autonomous vehicles that must navigate with each other on these roads. Neuro-Evolution, a method that combines evolutionary algorithms with neural networks, has shown to be effective in reinforcement-learning, multi-agent tasks such as maze navigation, biped locomotion, autonomous racing vehicles and fin-less rocket control. Hence, a neuro-evolution method is selected and investigated for the controller evolution of collective autonomous vehicles in homogeneous teams. The impact of objective and non-objective search (and a combination of both, a hybrid method) for controller evolution is comparatively evaluated for robustness on a range of driving tasks and collection sizes. Results indicate that the objective search was able to generalise the best on unseen task environments compared to all other methods and the hybrid approach was able to yield desired task performance on evolution far earlier than both approaches but was unable to generalise as effectively over new environments.

Full textAbstract:
In children, joint hypermobility (typified by structural instability of joints) manifests clinically as neuro-muscular and musculo-skeletal conditions and conditions associated with development and organization of control of posture and gait (Finkelstein, 1916; Jahss, 1919; Sobel, 1926; Larsson, Mudholkar, Baum and Srivastava, 1995; Murray and Woo, 2001; Hakim and Grahame, 2003; Adib, Davies, Grahame, Woo and Murray, 2005:). The process of control of the relative proportions of joint mobility and stability, whilst maintaining equilibrium in standing posture and gait, is dependent upon the complex interrelationship between skeletal, muscular and neurological function (Massion, 1998; Gurfinkel, Ivanenko, Levik and Babakova, 1995; Shumway-Cook and Woollacott, 1995). The efficiency of this relies upon the integrity of neuro-muscular and musculo-skeletal components (ligaments, muscles, nerves), and the Central Nervous System’s capacity to interpret, process and integrate sensory information from visual, vestibular and proprioceptive sources (Crotts, Thompson, Nahom, Ryan and Newton, 1996; Riemann, Guskiewicz and Shields, 1999; Schmitz and Arnold, 1998) and development and incorporation of this into a representational scheme (postural reference frame) of body orientation with respect to internal and external environments (Gurfinkel et al., 1995; Roll and Roll, 1988). Sensory information from the base of support (feet) makes significant contribution to the development of reference frameworks (Kavounoudias, Roll and Roll, 1998). Problems with the structure and/ or function of any one, or combination of these components or systems, may result in partial loss of equilibrium and, therefore ineffectiveness or significant reduction in the capacity to interact with the environment, which may result in disability and/ or injury (Crotts et al., 1996; Rozzi, Lephart, Sterner and Kuligowski, 1999b).
Whilst literature focusing upon clinical associations between joint hypermobility and conditions requiring therapeutic intervention has been abundant (Crego and Ford, 1952; Powell and Cantab, 1983; Dockery, in Jay, 1999; Grahame, 1971; Childs, 1986; Barton, Bird, Lindsay, Newton and Wright, 1995a; Rozzi, et al., 1999b; Kerr, Macmillan, Uttley and Luqmani, 2000; Grahame, 2001), there has been a deficit in controlled studies in which the neuro-muscular and musculo-skeletal characteristics of children with joint hypermobility have been quantified and considered within the context of organization of postural control in standing balance and gait. This was the aim of this project, undertaken as three studies.
The major study (Study One) compared the fundamental neuro-muscular and musculo-skeletal characteristics of 15 children with joint hypermobility, and 15 age (8 and 9 years), gender, height and weight matched non-hypermobile controls. Significant differences were identified between previously undiagnosed hypermobile (n=15) and non-hypermobile children (n=15) in passive joint ranges of motion of the lower limbs and lumbar spine, muscle tone of the lower leg and foot, barefoot CoP displacement and in parameters of barefoot gait. Clinically relevant differences were also noted in barefoot single leg balance time. There were no differences between groups in isometric muscle strength in ankle dorsiflexion, knee flexion or extension.
The second comparative study investigated foot morphology in non-weight bearing and weight bearing load conditions of the same children with and without joint hypermobility using three dimensional images (plaster casts) of their feet. The preliminary phase of this study evaluated the casting technique against direct measures of foot length, forefoot width, RCSP and forefoot to rearfoot angle. Results indicated accurate representation of elementary foot morphology within the plaster images. The comparative study examined the between and within group differences in measures of foot length and width, and in measures above the support surface (heel inclination angle, forefoot to rearfoot angle, normalized arch height, height of the widest point of the heel) in the two load conditions. Results of measures from plaster images identified that hypermobile children have different barefoot weight bearing foot morphology above the support surface than non-hypermobile children, despite no differences in measures of foot length or width.
Based upon the differences in components of control of posture and gait in the hypermobile group, identified in Study One and Study Two, the final study (Study Three), using the same subjects, tested the immediate effect of specifically designed custom-made foot orthoses upon balance and gait of hypermobile children. The design of the orthoses was evaluated against the direct measures and the measures from plaster images of the feet. This ascertained the differences in morphology of the modified casts used to mould the orthoses and the original image of the foot. The orthoses were fitted into standardized running shoes. The effect of the shoe alone was tested upon the non-hypermobile children as the non-therapeutic equivalent condition. Immediate improvement in balance was noted in single leg stance and CoP displacement in the hypermobile group together with significant immediate improvement in the percentage of gait phases and in the percentage of the gait cycle at which maximum plantar flexion of the ankle occurred in gait.
The neuro-muscular and musculo-skeletal characteristics of children with joint hypermobility are different from those of non-hypermobile children. The Beighton, Solomon and Soskolne (1973) screening criteria successfully classified joint hypermobility in children. As a result of this study joint hypermobility has been identified as a variable which must be controlled in studies of foot morphology and function in children. The outcomes of this study provide a basis upon which to further explore the association between joint hypermobility and neuro-muscular and musculo-skeletal conditions, and, have relevance for the physical education of children with joint hypermobility, for footwear and orthotic design processes, and, in particular, for clinical identification and treatment of children with joint hypermobility.

Whilst literature focusing upon clinical associations between joint hypermobility and conditions requiring therapeutic intervention has been abundant (Crego and Ford, 1952; Powell and Cantab, 1983; Dockery, in Jay, 1999; Grahame, 1971; Childs, 1986; Barton, Bird, Lindsay, Newton and Wright, 1995a; Rozzi, et al., 1999b; Kerr, Macmillan, Uttley and Luqmani, 2000; Grahame, 2001), there has been a deficit in controlled studies in which the neuro-muscular and musculo-skeletal characteristics of children with joint hypermobility have been quantified and considered within the context of organization of postural control in standing balance and gait. This was the aim of this project, undertaken as three studies.
The major study (Study One) compared the fundamental neuro-muscular and musculo-skeletal characteristics of 15 children with joint hypermobility, and 15 age (8 and 9 years), gender, height and weight matched non-hypermobile controls. Significant differences were identified between previously undiagnosed hypermobile (n=15) and non-hypermobile children (n=15) in passive joint ranges of motion of the lower limbs and lumbar spine, muscle tone of the lower leg and foot, barefoot CoP displacement and in parameters of barefoot gait. Clinically relevant differences were also noted in barefoot single leg balance time. There were no differences between groups in isometric muscle strength in ankle dorsiflexion, knee flexion or extension.
The second comparative study investigated foot morphology in non-weight bearing and weight bearing load conditions of the same children with and without joint hypermobility using three dimensional images (plaster casts) of their feet. The preliminary phase of this study evaluated the casting technique against direct measures of foot length, forefoot width, RCSP and forefoot to rearfoot angle. Results indicated accurate representation of elementary foot morphology within the plaster images. The comparative study examined the between and within group differences in measures of foot length and width, and in measures above the support surface (heel inclination angle, forefoot to rearfoot angle, normalized arch height, height of the widest point of the heel) in the two load conditions. Results of measures from plaster images identified that hypermobile children have different barefoot weight bearing foot morphology above the support surface than non-hypermobile children, despite no differences in measures of foot length or width.
Based upon the differences in components of control of posture and gait in the hypermobile group, identified in Study One and Study Two, the final study (Study Three), using the same subjects, tested the immediate effect of specifically designed custom-made foot orthoses upon balance and gait of hypermobile children. The design of the orthoses was evaluated against the direct measures and the measures from plaster images of the feet. This ascertained the differences in morphology of the modified casts used to mould the orthoses and the original image of the foot. The orthoses were fitted into standardized running shoes. The effect of the shoe alone was tested upon the non-hypermobile children as the non-therapeutic equivalent condition. Immediate improvement in balance was noted in single leg stance and CoP displacement in the hypermobile group together with significant immediate improvement in the percentage of gait phases and in the percentage of the gait cycle at which maximum plantar flexion of the ankle occurred in gait.
The neuro-muscular and musculo-skeletal characteristics of children with joint hypermobility are different from those of non-hypermobile children. The Beighton, Solomon and Soskolne (1973) screening criteria successfully classified joint hypermobility in children. As a result of this study joint hypermobility has been identified as a variable which must be controlled in studies of foot morphology and function in children. The outcomes of this study provide a basis upon which to further explore the association between joint hypermobility and neuro-muscular and musculo-skeletal conditions, and, have relevance for the physical education of children with joint hypermobility, for footwear and orthotic design processes, and, in particular, for clinical identification and treatment of children with joint hypermobility.

Previous issue date: 2013-03-04In this study, I discuss the discourse about the quotas for black people in the pages of Veja magazine. I established as a time frame for the research the years from 2009 to 2011. The main question of the study is to set how the discourse in the weekly magazine is constituted. Thus, the central objective of this work, supported by the theoretical principles of the French Discourse Analysis, is to comprehend how the discursive process about the quotas for black people in the magazine is constituted during the established time frame, time in which the topic is in a strong debate in the National Congress of Brazil and in the Federal Supreme Court, also gaining the pages of the press. The study is based mainly on studies of Mariani (1998), Moura (2004), Orlandi (2007a [1999], 2007b [1992]) and Pêcheux (2009 [1988], 2008 [1990]). Through online research at the address
Neste trabalho abordo o discurso a respeito das cotas para negros presente nas páginas da revista Veja. Estabeleci como recorte temporal da pesquisa os anos de 2009 a 2011. A questão central do estudo é traçar como se constitui o discurso do semanário sobre as cotas. Assim, o objetivo geral do trabalho, sustentado nos pressupostos teóricos da Análise do Discurso Francesa, é compreender como se constitui o processo discursivo sobre as cotas para negros no semanário durante o recorte temporal estabelecido, período no qual o tema está em intenso debate no Congresso Nacional e no Supremo Tribunal Federal, tomando também as páginas da imprensa. O trabalho está fundamentado, principalmente, nos estudos de Mariani (1998), Moura (2004), Orlandi (2007a [1999], 2007b [1992]), e Pêcheux (2009 [1988], 2008 [1990]).

Full textAbstract:
El Ordenamiento Territorial en la actualidad es considerado como instrumento de primer orden para la planificación física, ya que muestra la imagen objetivo de la política económica, social y cultural del Estado, que en nuestro caso, se manifiesta en el abandono de casi las 2/3 partes del territorio peruano. De ahí, la urgente necesidad de iniciar los estudios conducentes al nuevo ordenamiento, reordenamiento, acondicionamiento y reorganización espacial, con la consiguiente delimitación territorial que complementará o coadyuvará con la política de descentralización antes que la regionalización, convirtiéndose de esta manera en política de Estado.
En esta perspectiva, considerar el Ordenamiento Territorial como instrumento para fines específicos como la planificación del Turismo Sostenible es fundamental, sobre todo en el área andina como la cuenca del río Negro, en donde las condiciones ambientales, socioeconómico-culturales de la población se vienen eteriorando en estos últimos tiempos de manera alarmante por una serie de factores propiamente geográficas como el cambio climático, proceso de desertificación, entre otros, que vienen siendo acelerados por la intervención del hombre, los mismos que merecen ser mitigados a corto y mediano plazo y con propuestas acorde al tiempo, realidad y condiciones locales y que no requieran ingentes cantidades de inversión y lo más importante con la participación organizada de la población.Tesis

Full textAbstract:
En el presente trabajo de tesis se diseña un sistema Neuro-difuso para automatizar el proceso de transporte de cargas que realiza una Grúa Torre.
Debido a que no se ha podido disponer de una Grúa Torre real ni de un prototipo a escala, se ha optado por diseñar un simulador 3D de Grúa Torre que puede ser operado tanto manualmente, a través de un panel de botones en la pantalla, como automáticamente, cuando se inserta algún algoritmo de control. Durante el estudio teórico se ha tenido acceso a trabajos de investigación de la universidad Virginia Tech (Virginia Polytechnic Institute and State University – USA) referidos al estudio de la automatización de grúas, pero se ignoran los detalles del simulador utilizado en ellos; por este motivo, se ha sometido a prueba el simulador de la presente tesis aplicando los algoritmos de control publicados por los investigadores de dicha universidad. Al haber obtenido respuestas similares a las publicadas, se verificó que el simulador propuesto es equivalente al utilizado en aquellos trabajos. Por tanto, se tuvo la certeza de haber diseñado un simulador confiable que permitiese, posteriormente, probar el desempeño del sistema de automatización Neuro-difuso.
La operación manual del simulador, emulando la labor de un obrero de construcción, ha permitido extraer datos experimentales para obtener una base de datos del funcionamiento de la Grúa Torre. Del total de valores experimentales, se seleccionaron los más representativos a través de un proceso de agrupamiento de datos o clusterización (clustering). Esta etapa, así como las demás etapas del diseño del algoritmo Neuro-difuso, se realizó utilizando el entorno de desarrollo fuzzyTECH del Instituto de Investigación de la FIE-UNMSM. Posteriormente, el sistema Neuro-difuso fue probado en el simulador 3D, en su modo de operación automático, y los resultados fueron comparados con los obtenidos al aplicar los algoritmos de las tesis de PostGrado de Virginia Tech en el simulador.
Finalmente, se logró demostrar que un Sistema de Automatización Neuro-difuso para una Grúa Torre es tan eficiente como los desarrollados a través de métodos clásicos, con la ventaja de ser más fácil de diseñar ya que no necesita de modelos matemáticos, sino de datos de su operación manual.Tesis
