1 TITLE: Specifics of womans ice hockey AUTHOR: Michaela Hrbková DEPARTMENT: Physical Education Department SUPERVISOR: PaedDr. Ladislav Pokorný ABSTRAKT: This master thesis shows specific differences between men's and women's ice hockey. Point out anatomical, physiological, psychological, performance, technical and tactical factors affecting training processes and training units in men's and women's ice hockey. Using a questionnaire among players and coaches, I examined the knowledge of specific gender needs and their placement in the training units, knowledge of competition systems and game plans, differences in rules and men's and women's ice hockey. Furthermore, player and coaching history and hockey coaching education. Using a questionnaire among public, I examined opinions on female players and women's ice hockey, differences in attendance and viewership of men's and women's matches, knowledge of male and female players, teams and international successes of national hockey teams. I compared average age, weight and height of male players in Tipsport Extraliga and female players in women's league. I also compared the amount of training units of men's team HC Verva Litvínov and women's team HC Litvínov in the season 2014/2015. KEYWORDS: Woman, ice hockey, differences, specifics, sports training,...

This thesis analyses the public art competitions arranged by the Public Art Agency Sweden (Statens konstråd) 1937-1970 and the discussions about public art competitions in within the art field of the 1940’s, -50’ and -60’s. The main material for this analysis has been the protocols of the Public Art Agency and the annual paper of the Swedish Artists' National Organization (Konstnärernas riksorganisation). The theoretical and methodological framework is based on Pierre Bourdieu’s understanding of the art field, and institutions as agents within that field. I also use Foucauldian discourse theory as another theoretical tool to understand the power relations between these institutions in the art field. My aim has been to understand why there were competitions for public art commissions – the purposes, the processes, the discussions and how these factors change over the decades. The purpose for public art competition can be understood through the ideology of the Swedish welfare state and the cultural policy of the Social Democratic government in the 1930’s. The public art competitions could support the Swedish artists economically, but was also a way for the Swedish Government, through the Public Art Agency, to control and guarantee that the public artworks were of high artistic quality. This idea of artistic quality became more and more dominant as a purpose for the competitions through the 1950’s and 1960’s.  The artists active in the Swedish Artists' National Organization found the competitions to be of great importance and the competitions were much discussed in the organisations annual paper. Many of the artists that discussed the artist competitions were of the same generation born in the 1910’s or 1920’s and were working with public art commissions to a great extent. For them, the public art competitions gave recognition and a possible income. My analysis also shows that the public art competitions were also connected to the concept of modernism. The status of the competitions changed along with the changing concept of modernism. The competition was at its highest status in the 1930’s and 1940’s, when many artists were engaged in public art commissions. It became less popular among young artists in the 1960’s, when the art field was more politically radical and critical against authorities.

This thesis is about the creation of a simulator of football leagues and championships. I studied the problematics of football competitions and their systems and also about the base of machine learning. There was also an analysis of similar and existing solutions and I took inspiration for my proposal from them. After that, I made the design of the whole simulator structure and of all of its key parts. Then the simulator was implemented and tested. The application allows simulating top five competitions in UEFA club coefficients rating.

Insbesondere für kleine und mittlere Softwareunternehmen stellen die Erhöhung der eigenen Innovationskraft und -geschwindigkeit entscheidende Überlebensfragen dar. Der heute als hierfür wichtig hervorgehobene Ansatz der „Open Innovation“ hat sich in der Softwareentwicklungsbrache bislang jedoch kaum durchgesetzt, obwohl den Kunden bzw. Anwendern von Softwareprodukten wegen ihres im Umgang mit den Softwareprodukten gewonnenen Erfahrungswissens ein großes Innovationspotenzial nachgesagt werden kann. Die Durchführung von Ideenwettbewerben stellt in diesem Zusammenhang eine leicht adaptierbare und kostengünstige Methode der Kundenintegration dar. Ziel dieses Beitrages ist, IT-gestützte Ideenwettbewerbe als ein vielversprechendes theoretisches Konzept zur Integration von Kunden in das Innovationsmanagement von Softwareunternehmen vorzustellen.

Cette thèse contribue à une théorie générale de la conception du projet. S’inscrivant dans une demande marquée par les enjeux du développement durable, l’objectif principal de cette recherche est la contribution d’un modèle théorique de la conception permettant de mieux situer l’utilisation des outils et des normes d’évaluation de la durabilité d’un projet. Les principes fondamentaux de ces instruments normatifs sont analysés selon quatre dimensions : ontologique, méthodologique, épistémologique et téléologique. Les indicateurs de certains effets contre-productifs reliés, en particulier, à la mise en compte de ces normes confirment la nécessité d’une théorie du jugement qualitatif. Notre hypothèse principale prend appui sur le cadre conceptuel offert par la notion de « principe de précaution » dont les premières formulations remontent du début des années 1970, et qui avaient précisément pour objectif de remédier aux défaillances des outils et méthodes d’évaluation scientifique traditionnelles. La thèse est divisée en cinq parties. Commençant par une revue historique des modèles classiques des théories de la conception (design thinking) elle se concentre sur l’évolution des modalités de prise en compte de la durabilité. Dans cette perspective, on constate que les théories de la « conception verte » (green design) datant du début des années 1960 ou encore, les théories de la « conception écologique » (ecological design) datant des années 1970 et 1980, ont finalement convergé avec les récentes théories de la «conception durable» (sustainable design) à partir du début des années 1990. Les différentes approches du « principe de précaution » sont ensuite examinées sous l’angle de la question de la durabilité du projet. Les standards d’évaluation des risques sont comparés aux approches utilisant le principe de précaution, révélant certaines limites lors de la conception d’un projet. Un premier modèle théorique de la conception intégrant les principales dimensions du principe de précaution est ainsi esquissé. Ce modèle propose une vision globale permettant de juger un projet intégrant des principes de développement durable et se présente comme une alternative aux approches traditionnelles d’évaluation des risques, à la fois déterministes et instrumentales. L’hypothèse du principe de précaution est dès lors proposée et examinée dans le contexte spécifique du projet architectural. Cette exploration débute par une présentation de la notion classique de «prudence» telle qu’elle fut historiquement utilisée pour guider le jugement architectural. Qu’en est-il par conséquent des défis présentés par le jugement des projets d’architecture dans la montée en puissance des méthodes d’évaluation standardisées (ex. Leadership Energy and Environmental Design; LEED) ? La thèse propose une réinterprétation de la théorie de la conception telle que proposée par Donald A. Schön comme une façon de prendre en compte les outils d’évaluation tels que LEED. Cet exercice révèle cependant un obstacle épistémologique qui devra être pris en compte dans une reformulation du modèle. En accord avec l’épistémologie constructiviste, un nouveau modèle théorique est alors confronté à l’étude et l’illustration de trois concours d'architecture canadienne contemporains ayant adopté la méthode d'évaluation de la durabilité normalisée par LEED. Une série préliminaire de «tensions» est identifiée dans le processus de la conception et du jugement des projets. Ces tensions sont ensuite catégorisées dans leurs homologues conceptuels, construits à l’intersection du principe de précaution et des théories de la conception. Ces tensions se divisent en quatre catégories : (1) conceptualisation - analogique/logique; (2) incertitude - épistémologique/méthodologique; (3) comparabilité - interprétation/analytique, et (4) proposition - universalité/ pertinence contextuelle. Ces tensions conceptuelles sont considérées comme autant de vecteurs entrant en corrélation avec le modèle théorique qu’elles contribuent à enrichir sans pour autant constituer des validations au sens positiviste du terme. Ces confrontations au réel permettent de mieux définir l’obstacle épistémologique identifié précédemment. Cette thèse met donc en évidence les impacts généralement sous-estimés, des normalisations environnementales sur le processus de conception et de jugement des projets. Elle prend pour exemple, de façon non restrictive, l’examen de concours d'architecture canadiens pour bâtiments publics. La conclusion souligne la nécessité d'une nouvelle forme de « prudence réflexive » ainsi qu’une utilisation plus critique des outils actuels d’évaluation de la durabilité. Elle appelle une instrumentalisation fondée sur l'intégration globale, plutôt que sur l'opposition des approches environnementales. / This thesis is a contribution to the general theory of design thinking. In the prevalent demand for a sustainable development, the main objective of this research is the construction of a theoretical model of design thinking that contextualizes standard sustainability evaluation tools. The basis of these normative tools is analyzed in four dimensions: ontological, methodological, epistemological and teleological. Indications of potential counter-productive effects of these norms for design thinking confirm the need for a theory of qualitative judgment. Our central hypothesis revolves around the benefits of the underlying conceptual framework of the ‘precautionary principle’ for design thinking, the first formulations of which goes back to the early seventies in Germany, and was in fact created as a way to address the failures of traditional scientific evaluation tools or methods. The thesis comprises five parts. Beginning with a historical perspective, a review of classical models of design thinking, specifically focuses on the evolving approaches for addressing sustainable development. Theories of “green design” coming from the early sixties, theories of ecological design of the seventies and eighties are finally converging on the developing theories of “sustainable design” formulated in the early nineties. The underlying theories of the precautionary principle are then reviewed and explored for the specific context of design within the perspective of sustainability. Current methods of standard risk assessment methods are compared to a precautionary approach, revealing their conceptual limits for design thinking. A preliminary theoretical model for design thinking is then constructed adopting the theories underlying the precautionary principle. This model represents a global vision for judging the design project in a context of sustainability, rather than on traditional approaches for risk assessment, which are purposive and instrumental. The precautionary principle is further explored for the specific context of architectural design. This exploration begins with a historical perspective of the classical notion of ‘prudence’ for guiding architectural judgment. In light of the contemporary issues related to sustainability, we then examine the challenges of judging architectural projects given the increasing international prominence of such standard evaluation methods (i.e. Leadership in Energy and Environmental Design, LEED). The thesis proposes a reinterpretation of design thinking as proposed by Donald A. Schön is introduced such that the use of tools, like LEED can be contextualized. This exercise reveals an epistemological barrier, which shall be taken into consideration when reformulating the theoretical model. In accordance with a constructivist epistemology, a new theoretical model is therefore confronted to the study and illustration of three contemporary Canadian architectural competitions adopting the standard evaluation method LEED. A preliminary set of ‘tensions’ identified in the judgment process and design thinking is further categorized into their conceptual counterparts. These are: (1) analogical/logical conceptualization; (2) epistemological/methodological uncertainty; (3) interpretive/analytic comparability; and (4) universal/contextual relevance of the proposal. These conceptual tensions are considered as vectors that come into correlation with the theoretical model, enriching it, yet without validating it, in the positivist sense of the word. These confrontations with the real, help better define the epistemological barrier identified above. This thesis therefore highlights the often underestimated impact of environmental standards on the judgment process and design thinking, with particular, albeit non restrictive, reference to contemporary Canadian architectural competitions for public buildings. It concludes by stressing the need for a new form of “reflective prudence” in design thinking along with a more critical use of current evaluation tools for sustainability founded on a global integration rather than on the opposition of environmental approaches.

La lentille (Lens culinaris Med.) est une composante importante des régimes alimentaires de nombreuses populations à travers le monde mais sa consommation en Europe est relativement faible. L’Europe produit seulement 26% de sa consommation de lentille et ce déficit est en partie causé par d’importants verrous agronomiques comme la verse, les bruches et la compétition des adventices qui réduisent ses rendements, notamment en agriculture biologique. Les associations de cultures, définies comme la culture simultanée d’au moins deux espèces différentes sur une même surface pendant une durée significative, sont considérées comme une option pour lever ces verrous agronomiques et ainsi développer la production de lentille en agriculture biologique. Les objectifs de cette thèse étaient de (1) évaluer le potentiel des associations de lentille et de blé de printemps pour produire de la lentille en conditions d’agriculture biologique et (2) comprendre les principaux mécanismes sous-jacents à la performance des associations. Des essais agronomiques ont été mis en place en 2015 et 2016 en conditions d’agriculture biologique. Quatre variétés de lentille et de blé de printemps ont été conduites en culture pures et en plusieurs associations de type substitutif et additif. Nos résultats montrent que le rendement moyen des associations avant récolte mécanique était plus élevé que le rendement moyen des cultures pures. Néanmoins, le rendement de lentille en association était inférieur à celui de la lentille en culture pure en raison d’une compétition forte et précoce du blé pour les ressources qui a causé la diminution nombre de ramifications par plante de la lentille. Le prix de la lentille étant environ quatre fois plus élevé que celui du blé, la marge brute des associations avant récolte était inférieure à celle de la lentille en culture pure. Cependant, la verse de la lentille a été fortement réduite en association, entrainant une augmentation de l’efficacité de sa récolte mécanique. En conséquence les rendements de lentille issus de la récolte mécanique se sont avérés similaires en association et en culture pure. Enfin, après tri et nettoyage des graines, la marge brute des associations sur le rendement commercialisable était supérieure à celle des cultures pures. Nos résultats montrent que (1) les associations n’ont pas eu d’effet sur le taux de bruchage des lentilles, (2) l’association la plus performante est constituée de lentille à densité équivalente à la culture pure dans laquelle on ajoute 15-20% de blé, (3) la performance des associations est due à une utilisation complémentaire de l’azote rendue possible par la fixation symbiotique de l’azote par la lentille et (4) l’intensité des compétitions entre espèces dépendent de l’année, de la densité de blé et des génotypes. En conclusion, nos travaux indiquent que les associations de lentille et de blé de printemps peuvent permettre de développer la production de lentille en agriculture biologique mais qu’une meilleure compréhension des interactions de type génotype x environnement x conduite pourrait permettre de mettre au point des couverts encore plus performants. / Lentil (Lens culinaris Med.) is an important component of the human diet in the world, but in the meantime, Europe produces only 26% of the lentils it consumes. This is partly due to strong agronomic weaknesses that reduce yield such as lodging, bruchid beetles and weeds, especially in organic farming. Intercropping, the simultaneous growing of two or more species in the same field is tested here as an option to reduce these drawbacks and develop organic lentil production. The aims of this thesis were to (1) assess the potential of lentil-spring wheat intercrops to produce organic lentil, (2) understand the mechanisms that explain their performances, and (3) evaluate the profitability of such intercrops. A two-year field experiment was carried out in southwestern France in 2015 and 2016 under organic farming rules. Four lentil and two wheat cultivars were grown as sole crops and intercrops in multiple additive and substitutive designs. Our results showed that the total intercrop attainable grain yield was higher than the mean of sole crops. Yet, lentil yield in intercrop was lower than in sole crop as the result of a strong competition for resources from wheat in early lentil growth stages reducing the number of branches per plant of lentil. This led to lower gross margins of intercrops. However, lentil lodging was strongly reduced in intercrops thus its mechanical harvest efficiency increased. This led to similar mechanically harvested yields of lentil in intercrop and sole crop. Consequently, after mechanical harvest and grain cleaning, the marketable gross margin of intercrops was higher than that of sole crops. Our results suggest that (1) intercrop had no effect on bruchids, (2) the most effective intercrop is when lentil is at sole crop density and wheat at 15-20%, (3) intercrop performance is due to complementary use of N pools through legume N2 fixation and (4) the intensity of interspecific interactions depends on year, wheat density and genotypes. Our work indicates that lentil-spring wheat intercrop can develop organic lentil production but a better understanding of Genotype x Environment x Cropping system interactions may be useful to design optimized managements.

Esta dissertação pretende discutir a unidade e a pluralidade no meio arquitetônico paulista, a partir de suas redes de sociabilidade, espaços de profissionalização e movimentações críticas, tendo como material primário as revistas especializadas publicadas na cidade no período de 1945 a 1965. Trata-se de percorrer a dupla direção das relações entre um grupo intelectual - uma parcela de arquitetos atuantes na cidade - e suas manifestações, procurando traçar o espaço particular no qual se desenvolveram parte de seus laços profissionais, de suas trocas culturais e ideológicas, e de seus posicionamentos projetuais. Operando na intersecção entre espaço urbano, organizações culturais, instituições profissionais e acadêmicas, o primeiro capítulo procura traçar as redes de sociabilidade dos arquitetos em São Paulo. O segundo capítulo busca percorrer os meandros da crítica paulista - suas aproximações, desarticulações, rupturas e deslocamentos críticos - a partir de seus diálogos internos e dos diversos olhares lançados sobre a arquitetura contemporânea no Brasil, principalmente aquela produzida no Rio de Janeiro. Por fim, o terceiro capítulo é uma tentativa de aproximação das interlocuções projetuais entre os arquitetos locais através da análise de alguns dos concursos de arquitetura realizados em São Paulo no período e que encontraram eco nas revistas de arquitetura locais. / This work intends to discuss the unity and plurality of the architectonic environment of São Paulo, through their social networks, professional spaces and critical movements, using as primary source some specialized magazines, published in the city between 1945 and 1965. The study will investigate the relationship between an intellectual group - a parcel of architects working in São Paulo - and its manifestations, seeking to understand the particular space in which some of its professional ties, cultural and ideological exchanges, and projetual attitudes were developed. The first chapter seeks to outline the social networks of those architects, through the intersection of urban space, cultural, professional and academic institutions. The second chapter studies the local criticism - their intellectual approaches, disarticulations, fractures and dislocations - across their inner dialogues and their different looks launched on Brazilian contemporary architecture, especially the one produced in Rio de Janeiro. Finally, the third chapter aims to approach the projectual dialogues between the local architects through the analysis of some architectural competition held in São Paulo in the period and that found an echo in local architecture magazines.
