A Eficácia do Programa Fifa 11+ na Prevenção de Lesões em Atletas de Futebol Sub18

Introdução: No futebol, as lesões são da mais fulcral importância pelo que a sua prevenção se revela de extrema pertinência. A FIFA criou o FIFA 11+, um programa de prevenção de lesões, que revelou resultados positivos em equipas jovens tanto femininas como masculinas. No entanto, em Portugal, os resultados da sua implementação são escassos, principalmente em camadas jovens. Objetivo: Estudar a eficácia do programa FIFA 11+ na prevenção de lesões em atletas de futebol – sub 18. Métodos: O presente estudo quasi experimental teve como amostra uma equipa de 24 atletas, divididos voluntariamente em 2 grupos: o grupo experimental (GE) (n=12), e o grupo controlo (GC) (n= 12). Ambos os grupos realizaram os treinos normais sendo o grupo experimental sujeito adicionalmente ao programa FIFA 11+ duas vezes por semana, durante 12 semanas. Foi utilizado ainda o Orchard Sports Injury Classification System (OSICS-10) como sistema de classificação de lesões, sendo estas divididas em graves, moderadas, leves e mínimas. O teste Mann-Whitney foi utilizado para a comparação entre grupos, e o teste de Wilcoxon para a comparação intra grupo. Resultados: Quando comparados o GE com o GC em M0 não se observaram diferenças estatisticamente significativas (p=0.065), no número de lesões entre os grupos. O mesmo se verificou após a implementação do programa FIFA 11+ (p=1,000). Na comparação intra-grupo de M0 e M1 o grupo controlo não apresentou diferenças estatisticamente significativas (p=0,317) enquanto que no grupo experimental se observou que existiam significativamente menos lesões após a implementação do programa. (p=0,025). Conclusão: O programa FIFA 11+ parece ser indicado para a prevenção e diminuição de lesões desportivas em jogadores amadores de equipas sub-18, quando aplicado duas vezes por semana. Apesar disso, para eleger o programa como uma ferramenta de eleição na promoção da saúde, mais estudos são sugeridos utilizando uma amostra maior e se possível num período superior.

Otimização energética à secção das malhas

A presente dissertação realizada na empresa Continental-Indústria Têxtil do Ave, S.A., teve como objetivo a otimização energética da secção das malhas. Esta secção divide-se em duas áreas, a tricotagem e a ramulagem. Os artigos produzidos diferem no seu peso específico, composição e condições de operação, sendo os artigos A, B e C compostos por poliéster e termofixados a 190ºC e os artigos D e E compostos por poliéster e algodão, com uma temperatura de operação de 205ºC. Numa primeira etapa estudou-se o funcionamento da máquina de termofixação – a râmula – que opera em trabalho contínuo a 40 m/min. Esta máquina tem incorporado um permutador de calor, que aquece o ar fresco de entrada com os gases de exaustão das estufas. Posteriormente efetuou-se o levantamento energético de cada artigo, para as áreas de tricotagem e ramulagem. Verificou-se que os artigos D e E, pela sua constituição, são os que apresentam um consumo específico superior, em tep/ton. Entre as várias utilidades consumidas (gás natural, eletricidade e ar comprimido) o gás natural representa mais de 50% do consumo de energia total necessário para a produção de cada artigo. Após a completa análise aos consumos energéticos da râmula, foram realizados ensaios de otimização, tendo-se concluído que a diminuição do caudal de exaustão pode atingir valores de poupança anual de gás natural na ordem dos 3.000 €. Com o objetivo de avaliar o consumo de gás natural, não sendo possível a realização experimental, foram feitas simulações com base em alterações na corrente de entrada de ar fresco no permutador. Foi também estudada a possibilidade de isolamento e revestimento térmico da conduta exterior, projetada para o reaproveitamento do ar dos compressores, tendo-se obtido um orçamento de 2.500 €. Admitindo-se uma gama de temperaturas entre os 40ºC e os 60ºC, com um caudal de insuflação de 30%, obteve-se um payback entre os 0,97 e os 3,28 anos. Numa segunda fase admitiu-se uma temperatura média de 50ºC, aumentando o caudal de insuflação até 100%. O período de retorno obtido variou entre os 0,33 e os 1,38 anos, podendo as poupanças anuais atingirem os 7.600 €.

New York City: "gilt cage" or "promised land" ? : representations of urban space in Edith Wharton and Anzia Yezierska

This thesis explores the importance of literary New York City in the urban narratives of Edith Wharton and Anzia Yezierska. It specifically looks at the Empire City of the Progressive Period when the concept of the city was not only a new theme but also very much a typical American one which was as central to the American experience as had been the Western frontier. It could be argued, in fact, that the American city had become the new frontier where modern experiences like urbanization, industrialization, immigration, and also women's emancipation and suffrage, caused all kinds of sensations on the human scale from smoothly lived assimilation and acculturation to deeply felt alienation because of the constantly shifting urban landscape. The developing urban space made possible the emergence of new female literary protagonists like the working girl, the reformer, the prostitute, and the upper class lady dedicating her life to 'conspicuous consumption'. Industrialization opened up city space to female exploration: on the one hand, upper and middle class ladies ventured out of the home because of the many novel urban possibilities, and on the other, lower class and immigrant girls also left their domestic sphere to look for paid jobs outside the home. New York City at the time was not only considered the epicenter of the world at large, it was also a city of great extremes. Everything was constantly in flux: small brownstones made way for ever taller skyscrapers and huge waves of immigrants from Europe pushed native New Yorkers further uptown on the island, adding to the crowdedness and intensity of the urban experience. The city became a polarized urban space with Fifth Avenue representing one end of the spectrum and the Lower East Side the other. Questions of space and the urban home greatly mattered. It has been pointed out that the city setting functions as an ideal means for the display of human nature as well as social processes. Narrative representations of urban space, therefore, provide a similar canvas for a protagonist's journey and development. From widely diverging vantage points both Edith Wharton and Anzia Yezierska thus create a polarized city where domesticity is a primal concern. Looking at all of their New York narratives by close readings of exterior and interior city representations, this thesis shows how urban space greatly affects questions of identity, assimilation, and alienation in literary protagonists who cannot escape the influence of their respective urban settings. Edith Wharton's upper class "millionaire" heroines are framed and contained by the city interiors of "old" New York, making it impossible for them to truly participate in the urban landscape in order to develop outside of their 'Gilt Cages'. On the other side are Anzia Yezierska's struggling "immigrant" protagonists who, against all odds, never give up in their urban context of streets, rooftops, and stoops. Their New York City, while always challenging and perpetually changing, at least allows them perspectives of hope for a 'Promised Land' in the making. Central for both urban narrative approaches is the quest for a home as an architectural structure, a spiritual resting place, and a locus for identity forming. But just as the actual city embraces change, urban protagonists must embrace change also if they desire to find fulfillment and success. That this turns out to be much easier for Anzia Yezierska's driven immigrants rather than for Edith Wharton's well established native New Yorkers is a surprising conclusion to this urban theme.

Lagrangian-informed mixed integer programming reformulations

La programmation linéaire en nombres entiers est une approche robuste qui permet de résoudre rapidement de grandes instances de problèmes d'optimisation discrète. Toutefois, les problèmes gagnent constamment en complexité et imposent parfois de fortes limites sur le temps de calcul. Il devient alors nécessaire de développer des méthodes spécialisées afin de résoudre approximativement ces problèmes, tout en calculant des bornes sur leurs valeurs optimales afin de prouver la qualité des solutions obtenues. Nous proposons d'explorer une approche de reformulation en nombres entiers guidée par la relaxation lagrangienne. Après l'identification d'une forte relaxation lagrangienne, un processus systématique permet d'obtenir une seconde formulation en nombres entiers. Cette reformulation, plus compacte que celle de Dantzig et Wolfe, comporte exactement les mêmes solutions entières que la formulation initiale, mais en améliore la borne linéaire: elle devient égale à la borne lagrangienne. L'approche de reformulation permet d'unifier et de généraliser des formulations et des méthodes de borne connues. De plus, elle offre une manière simple d'obtenir des reformulations de moins grandes tailles en contrepartie de bornes plus faibles. Ces reformulations demeurent de grandes tailles. C'est pourquoi nous décrivons aussi des méthodes spécialisées pour en résoudre les relaxations linéaires. Finalement, nous appliquons l'approche de reformulation à deux problèmes de localisation. Cela nous mène à de nouvelles formulations pour ces problèmes; certaines sont de très grandes tailles, mais nos méthodes de résolution spécialisées les rendent pratiques.

Behavioral Measures and their Correlation with IPM Iteration Counts on Semi-Definite Programming Problems

We study four measures of problem instance behavior that might account for the observed differences in interior-point method (IPM) iterations when these methods are used to solve semidefinite programming (SDP) problem instances: (i) an aggregate geometry measure related to the primal and dual feasible regions (aspect ratios) and norms of the optimal solutions, (ii) the (Renegar-) condition measure C(d) of the data instance, (iii) a measure of the near-absence of strict complementarity of the optimal solution, and (iv) the level of degeneracy of the optimal solution. We compute these measures for the SDPLIB suite problem instances and measure the correlation between these measures and IPM iteration counts (solved using the software SDPT3) when the measures have finite values. Our conclusions are roughly as follows: the aggregate geometry measure is highly correlated with IPM iterations (CORR = 0.896), and is a very good predictor of IPM iterations, particularly for problem instances with solutions of small norm and aspect ratio. The condition measure C(d) is also correlated with IPM iterations, but less so than the aggregate geometry measure (CORR = 0.630). The near-absence of strict complementarity is weakly correlated with IPM iterations (CORR = 0.423). The level of degeneracy of the optimal solution is essentially uncorrelated with IPM iterations.

Problemas y consecuencias del resurgir del pragmatismo norteamericano: 1952-1976

Revisión crítica de la ‘versión heredada’ sobre el resurgir del pragmatismo norteamericano. Aquí sostengo que ésta es una narrativa sobre la historia de la filosofía que puede ser usada para “reivindicar” la continuidad o para “añorar” la pérdida de esa tradición. Presento tres argumentos a favor de mi tesis sobre la versión heredada: i) es insuficiente para explicar el surgimiento del pragmatismo; ii) es un tipo de narrativa que hace plausible una imagen de la filosofía; iii) impide apreciar que la formación del canon obedece a los propósitos de los seguidores del movimiento.

Meta-morphs: – being a mediator of the ‘thin’ place and ‘thin’ experience in the HE classroom. A paper on the experience of creating transformations in HE teaching and learning

The research which underpins this paper began as a doctoral project exploring archaic beliefs concerning Otherworlds and Thin Places in two particular landscapes - the West Coast of Wales and the West Coast of Ireland. A Thin Place is an ancient Celtic Christian term used to describe a marginal, liminal realm, beyond everyday human experience and perception, where mortals could pass into the Otherworld more readily, or make contact with those in the Otherworld more willingly. To encounter a Thin Place in ancient folklore was significant because it engendered a state of alertness, an awakening to what the theologian John O’ Donohue (2004: 49) called “the primal affection.” These complex notions and terms will be further explored in this paper in relation to Education. Thin Teaching is a pedagogical approach which offers students the space to ruminate on the possibility that their existence can be more and can mean more than the categories they believed they belonged to or felt they should inhabit. Central to the argument then, is that certain places and their inhabitants can become revitalised by sensitively considered teaching methodologies. This raises interesting questions about the role spirituality plays in teaching practice as a tool for healing in the twenty first century.

Proximal methods for nonlinear programming: double regularization and inexact subproblems

This paper describes the first phase of a project attempting to construct an efficient general-purpose nonlinear optimizer using an augmented Lagrangian outer loop with a relative error criterion, and an inner loop employing a state-of-the art conjugate gradient solver. The outer loop can also employ double regularized proximal kernels, a fairly recent theoretical development that leads to fully smooth subproblems. We first enhance the existing theory to show that our approach is globally convergent in both the primal and dual spaces when applied to convex problems. We then present an extensive computational evaluation using the CUTE test set, showing that some aspects of our approach are promising, but some are not. These conclusions in turn lead to additional computational experiments suggesting where to next focus our theoretical and computational efforts.

O processo de humanização: as bases constitutivas da subjetividade

Iniciando-se por uma descrição longitudinal, seguida de interpretação "a posteriori", obteve-se categorias relativas a cada dimensão do psiquismo. Estas, em seu caráter de transversalidade, foram tomadas como esteios para as explicações acerca da passagem do sujeito da condição biológica à condição de sujeito falante. O norteamento dessa análise teve como ponto de partida a postulação acerca dessas dimensões, dos aspectos relativos as mesmas, e dos efetores referentes por essa passagem, cujo início tem a esses aspectos que respondem lugar quando a mãe se dispõe a apontar para o sujeito o limite entre o núcleo filogenético e as transformações sócio-histórica. A partir dessa delimitação, ocorre a assimilação de características, tipicamente humanas para, enfim, serem fixados pela lei paterna, os limites do “tornar-se humano”. Nesse ínterim, são observadas ocorrências relativas as dimensões mencionadas. Tratando-se de permanência de conteúdos mantidos fora do campo da simbolização, e excluídos da matriz imaginária, tem-se então a caracterização do real ~elo seu mecanismo específico: a foraclusão. Ainda se situa a pulsão no seu caráter impensável e inominável. Já as ações resultantes do recalcamento originário concorrem para a formação de marcas não-simbolizáveis que, como faceta do imaginário, se vinculam às informações do núcleo filogenético referentes aos protofantasmas, aqui considerado corno outra faceta desta dimensão. No que concerne ao simbólico, registra-se a significação como fundante da condição humana, resultante do recalcamento propriamente dito. Sendo assim, a humanização enquanto explicada pelo conceito de recalcamento, conforme evidencia a metapsicologia freudiana, não açambarça todas as nuances relativas ao humano; visto englobar apenas aquilo que é imaginado corno fantasma ou aquilo que e apresentado simbolicamente. Por isso, a utilização do conceito de foraclusão, da perspectiva lacaniana, justifica-se pelo fato de oferecer uma visão mais completa dessa dinâmica. Desse modo, se pode incluir no escopo do "tornar-se humano", aqueles elementos não passíveis de simbolização, bem como aqueles da realidade pulsional que não se apresentam no texto do fantasma; mas que, ao se constituírem como um "pano-de-fundo", possibilitam que a conteúdos simbólicos e imaginários viabilizem a socialização. De resto, a socialização é um processo que, originado do simbólico, se assenta no imaginário tomado como base. Para isto, o real, em seu efeito marginal, possibilita o retorno ao simbólico. A partir daí, se verifica a utilização dos elementos culturais, que são descobertos em função daquilo que a atividade fantasmática suscita.

Um sonho distante: reflexões sobre acessibilidade nos conjuntos habitacionais do pmcmv faixa 1 na região metropolitana de Natal

This dissertation seeks to reflect on the accessibility of the governmental program Minha Casa Minha Vida, track 1, which comprehends people who made 0 to 3 minimum wages within the metropolitan region of Natal RN between the years of 2009 and 2012. The research covers the municipalities benefited by the program: Ceará-Mirim, Extremoz, Macaíba, Monte Alegre, Natal, Nísia Floresta, Parnamirim and São Gonçalo do Amarante. We have investigated the extensions of PMCMV on the context of the access to the city, debating some concepts attached to the capitalist mode of production such as residential segregation and peripherization. We have aimed to identify the accessibility conditions in the new housing complexes from three primal categories, namely, the localization of the complexes, the disponibility of public equipments, services, leisure and cultural properties on the neighborhood and the offer of public transport. Our theorical references are based on the ideas of the british geographer David Harvey on his work Social Justice and the City , from 1980. Harvey s studies made us debate on the locational choice for the social-matter habitation, and also let us discuss the price to accessibility on these new programs and its implications on the income of those who are benefited by them, specially because this is about a low-income population. To the achievement of these objectives, we made use of case study, including desk research, photographic documentation, records of field observations and informal conversations with locals, composing a qualitative study. In light of what has been researched and considering the guiding research questions, we reflect on aspects of the program that can greatly influence the processes of residential segregation and housing periphery of the lowincome population from the precarious conditions of accessibility to the referred population
