A escrita narrativa e a emergência das vozes sociais: uma aposta para a valorização da alteridade no (con)texto das ciências humanas e sociais

Defendemos a escrita narrativa de caráter polifônico como condição de possibilidade para a expressão do outro no (con)texto da pesquisa em ciências humanas e sociais e como posicionamento filosófico e epistemológico de caráter crítico e reflexivo que considera os interlocutores como co-construtores do conhecimento. Essa proposta visa valorizar a alteridade no texto científico explicitando sua importância. A discussão é fundamentada no referencial teórico metodológico das Práticas Discursivas e Produção de Sentidos que se pauta no Construcionismo SocialWe defend narrative-polyphonic writing as a condition of possibility for the expression of another in (con)texts of research in the humanities and social sciences and also as an epistemological and philosophical positioning with a critical and reflexive character for considering the interlocutors as co-builders of knowledge. This proposal intends to valorize otherness in scientific text. The discussion is grounded in theoretical-methodological field of Discursive Practices and Production of Senses that hinges on Social Constructionism

Uma demonstração alternativa para a representação de preferências variacionais

Dissertação (mestrado)—Universidade de Brasília, Faculdade de Administração, Contabilidade e Economia, Departamento de Economia, Programa de Pós-Graduação, 2014.Nós fornecemos uma demonstração alternativa de parte do principal resultado de Maccheroni, Marinacci e Rustichini (2006). Para isso, recorremos a um resultado de Faro (2012). Especificamente, utilizando o modelo de escolha sob incerteza baseado em Anscombe e Aumann (1968), caracterizamos as preferências para as quais existe uma função de utilidade u e um índice de ambiguidade c definido sobre o conjunto de probabilidades sobre os estados da natureza tais que, para todos os atos f e g, [Veja a fórmula no resumo do documento].

Context sensitive user interfaces

This paper presents a conceptual design model for user interfaces (MASS1) and a general formalism for dialogue specification (Interaction Scripts) which are the most important components of an approach to the methodological, iterative design of Interactive Systems from formal, model-based specification of both the application and the User Interface (UI). This approach allows the integration of both dialogue and application semantics from the beginning of the design process, by using prototypes derived from both specifications. Assuming that all the application semantics is available at early design stages, the MASS model defines a set of guidelines that will enforce the designer to create user interfaces that will present a prophylactic instead of the usual therapeutic behaviour. By a prophylactic behaviour it is meant, metaphorically, that the UI will exhibit a behaviour that prevents and avoids both syntactic and semantic user errors, in contrast with the most usual therapeutic, or error recovery, behaviour. The dialogue specification formalism(Interaction Scripts) despite being general, in the sense that it may be applied to the specification of any kind of dialogue, is specially suited to the specification of UIs with the behaviour prescribed by the MASS design model. In addition, it is independent from concrete environment details, therefore allowing for different implementations of the same specification, that is, different looks and feels. The operational semantics of the Interaction Script notation is also presented in terms of Petri-Nets that are automatically generated from the Interaction Script specification of the dialogue controller

In-season internal and external training load quantification of an elite European soccer team

Elite soccer teams that participate in European competitions need to have players in the best physical and psychological status possible to play matches. As a consequence of congestive schedule, controlling the training load (TL) and thus the level of effort and fatigue of players to reach higher performances during the matches is therefore critical. Therefore, the aim of the current study was to provide the first report of seasonal internal and external training load that included Hooper Index (HI) scores in elite soccer players during an in-season period. Nineteen elite soccer players were sampled, using global position system to collect total distance, high-speed distance (HSD) and average speed (AvS). It was also collected session rating of perceived exertion (s-RPE) and HI scores during the daily training sessions throughout the 2015-2016 in-season period. Data were analysed across ten mesocycles (M: 1 to 10) and collected according to the number of days prior to a one-match week. Total daily distance covered was higher at the start (M1 and M3) compared to the final mesocycle (M10) of the season. M1 (5589m) reached a greater distance than M5 (4473m) (ES = 9.33 [12.70, 5.95]) and M10 (4545m) (ES = 9.84 [13.39, 6.29]). M3 (5691m) reached a greater distance than M5 (ES = 9.07 [12.36, 5.78]), M7 (ES = 6.13 [8.48, 3.79]) and M10 (ES = 9.37 [12.76, 5.98]). High-speed running distance was greater in M1 (227m), than M5 (92m) (ES = 27.95 [37.68, 18.22]) and M10 (138m) (ES = 8.46 [11.55, 5.37]). Interestingly, the s-RPE response was higher in M1 (331au) in comparison to the last mesocycle (M10, 239au). HI showed minor variations across mesocycles and in days prior to the match. Every day prior to a match, all internal and external TL variables expressed significant lower values to other days prior to a match (p<0.01). In general, there were no differences between player positions. Conclusions: Our results reveal that despite the existence of some significant differences between mesocycles, there were minor changes across the in-season period for the internal and external TL variables used. Furthermore, it was observed that MD-1 presented a reduction of external TL (regardless of mesocycle) while internal TL variables did not have the same record during in-season match-day-minus.: The authors state that there were no salaries’ fund from a tobacco company.

In-season training load quantification of one-, two- and three-game week schedules in a top European professional soccer team

Top European soccer teams that play in UEFA competitions often participate in one, two- or three-games per week. Therefore, it is necessary to ensure optimal match-day performance and full recovery. The aim of this study was to quantify internal and external training load (TL) within five microcycles: M1 and M2 - one-game weeks; M3 and M4 - two-game weeks; M5 - three-game week). Thirteen elite soccer players participated in this study. A global positioning system (GPS) was used to measure the total distance covered and distances of different exercise training zones (1-5), the session ratings of perceived exertion (s-RPE) scores and the amount of creatine kinase (CK) created during daily training sessions for the 2015-2016 in-season period. The data were analysed with respect to the number of days prior to a given match. The main results indicate that there was a significant difference in training intensity for zone 1 between M2 and M4 (4010.2 ± 103.5 and 4507.6 ± 133.0 m, respectively); a significant difference in training intensity for zone 3 between M1 and M5 (686.1 ± 42.8 and 801.2 ± 61.2 m, respectively); a significant difference in the duration of the training sessions and matches between M2 and M5 (69.2 ± 2.1 and 79.6 ± 2.3) and M3 and M5 (69.7 ± 1.0 and 79.6 ± 2.3); and finally, there was a significant difference in CK between M3 and M2 (325.5 ± 155.0 and 194.4 ± 48.9). Moreover, there was a significant decrease in TL in the last day prior to a match, for all microcycles and all variables. There was no significant difference with respect to s-RPE. This study provides the first report of daily external and internal TLs and weekly accumulated load (training sessions and match demands) during one, two, and three-game week schedules in a group of elite soccer players. Expected significant differences are found in daily and accumulated loads for within- and between-game schedules. A similar pattern is exhibited for one- and two-game week microcycles regarding the day before the match, which exhibits a decrease in all variables. Despite the different number of games played per week, TL remain similar between microcycles for zone 2 and 5, plus s-RPE.This project was supported by the National Funds through FCT—Portuguese Foundation for Science and Technology (UID/DTP/04045/2013) and the European Fund for Regional Development (FEDER) allocated by European Union through the COMPETE 2020 Programme (POCI-01-0145-FEDER-006969)—competitiveness and internationalization (POCI).

Estresse e trabalho

TCC (especialização). Universidade Federal de Santa Catarina. Associação Catarinense de Medicina. Curso de Especialização em Medicina do TrabalhoA monografia destina-se ao XVI Curso de Medicina do Trabalho, em convênio com a Associação Catarinense de Medicina e Universidade Federal de Santa Catarina. O presente trabalho pretende realizar uma abordagem genérica, mostrando os diversos aspectos do estresse a que o homem esta submetido em seu cotidiano. Neste sentido desenvolveu-se uma ampla revisão e pesquisa bibliográfica de diversos especialistas ligados a esta área, através de livros, artigos, revistas. Iniciou-se essa tarefa, partindo de uma visão holística do ser humano; conceituando e estudando o histórico do stress pode-se, a priori desenvolver um embasamento teórico para o entendimento do estresse nos dias atuais; a partir desse estudo investigou-se as reações fisiológicas do estresse, seus efeitos fisiopatológicos, as repercussões em órgãos alvo, sua relação com o cérebro e o cortisol e, sua estreita ligação com ansiedade. Em um segundo momento exibiu-se as várias faces do estresse: a incidência entre brasileiros, a violência urbana e sua vinculação com o transtorno pós-traumático, o estresse profissional, as organizações e o ambiente de trabalho como fatores desencadeantes ( agentes estressantes ) e, aspectos atuais em relação ao tema. E finalmente, após descrever sobre o diagnóstico do estresse e sua prevenção através de métodos apresentados em recentes pesquisas como: ginástica laboral e auto-conhecimento, concluiu-se o presente trabalho. Ao profissionais da área de saúde, especialmente os que lidam com saúde ocupacional, devem estar atentos ao estresse, porque na grande maioria das vezes é a origem de muitos males de ordem física, além de desequilíbrio psicológicos, como a ansiedade e depressão, ou ainda sociais, como o desprezo e a desvalorização pessoal e profissional. Tais conhecimentos sobre o estresse e, as pressões do ambiente sobre o trabalhador, são importantes para a equipe interdisciplinar, pois o ser humano é um ser bio-psico-social

Jikan to Kukan:a hands-on musical experience in AI, games and art

AI is typically applied in video games in the creation of artificial opponents, in order to make them strong, realistic or even fallible (for the game to be “enjoyable” by human players). We offer a different perspective: we present the concept of “Art Games”, a view that opens up many possibilities for AI research and applications. Conference participants will play Jikan to Kukan, an art game where the player dynamically creates the soundtrack with the AI system, while developing her experience in the unconscious world of a character
