Qual é o gênero das lutas?: um estudo de caso sobre o boxe olímpico

A prática do boxe olímpico cresce a cada ano, porém esse aumento poderia ser mais significativo se o esporte não trouxesse consigo tantos preconceitos, estigmas e dificuldade para inserção na sociedade. As mulheres que optam pela prática do boxe olímpico freqüentemente são associadas ao que a sociedade considera como ‗masculino‘. Esse trabalho possui o objetivo de pesquisar quais são as questões relativas às relações de gênero existentes em praticantes femininos de boxe. Para tanto, procura investigar quais são as dificuldades, os preconceitos, os estigmas e as vantagens da prática do esporte, buscando relacioná-los com o projeto de extensão Boxe Olímpico, ministrado na UNESP – Rio Claro, no qual a orientanda é monitora. Para tal feito, a metodologia utilizada será uma pesquisa bibliográfica, ou seja, desenvolvimento de um levantamento, análise e discussão da bibliografia sobre o tema, bem como a pesquisa participante nas aulas ministradas no projeto de extensão. Ainda é evidente o preconceito em relação a praticantes femininos do boxe. Novos projetos e perspectivas acerca da prática do boxe olímpico são um começo de uma nova visão, dessa vez, contextualizada socialmente, culturalmente e historicamente. Além de proporcionarmos vivências reais e experienciais aos alunos, podemos também contemplar a descoberta de praticantes interessados no esporte de rendimento, mostrando que todas as possibilidades (iniciação e rendimento esportivo) são encontradas no esporte. Concluímos, portanto, que a reflexão, a discussão e o aprendizado sobre o boxe olímpico é uma possibilidade para a superação de preconceitos e dificuldades diante da prática feminina no esporte. Abrir novas portas e dar espaço para projetos que proporcionem, além da vivência, uma elucidação correta sobre o esporte é dar oportunidade para o esporte se desenvolver com maior facilidade.

Ensino de lutas e educação física escolar: o caso do currículo de educação física do estado de São Paulo

O atual cenário do ensino da Educação Física no Brasil caracteriza-se como um complexo campo de conflitos, no qual emergem e embrenham-se diferentes proposições teórico-metodológicas, originadas desde meados da década de 1980 no processo histórico de emancipação, superação e ressignificação da Educação Física. Tais concepções, em contraposição ao criticado e tradicional ensino técnico-esportivista, propõe que na escola os conteúdos abordados deveriam propiciar a apropriação crítica e autônoma das diversas manifestações da Cultura de Movimento. Sendo assim, cabe analisar como os professores, autores e não meros aplicadores, lidam com mudanças curriculares. É primordial analisar criticamente as práticas pedagógicas dos professores que vivenciam e implementam tais mudanças curriculares. O objetivo desta pesquisa foi investigar como se caracteriza a relação saberes docentes-ensino de lutas entre professores da rede pública estadual de São Paulo, no cenário de implementação do currículo oficial de Educação Física. Foi realizado um estudo de natureza qualitativa; os dados foram coletados por meio de entrevistas semi-estruturadas com professores e professoras atuantes na rede pública. Os resultados evidenciaram que o déficit na formação inicial dos professores, contribuiu para o trato pedagógico superficial do conteúdo lutas em suas aulas. Com isso, dificultando o desenvolvimento do conhecimento pedagógico do conteúdo dos docentes, que atribuem sua principal fonte de conhecimentos sobre o tema a recortes oriundos da influência midiática e da proposição de atividades a partir do Currículo de Educação Física do Estado de São Paulo. Percebemos aqui, a importância da construção do conhecimento pedagógico do conteúdo, para o desenvolvimento da base de conhecimentos do educador. Acreditamos, conforme Shulman, que é de suma importância que o professor/a domine uma base de...

Arremessadas da turma de caminhão: literatura e experiência traumática entre as trabalhadoras boias-frias na obra de Murilo Carvalho

This article investigates the universe of women seasonal farm workers, more precisely those women laborers who take the so-called truck, in the newspaper chronicle “Th e Seasonal Farm Workers’ Express” (1976) and the short story “Th e funny face of fear”(1978), both by the journalist and creative writer Murilo Carvalho. Th e hypothesis is that these two narratives, in which the theme is the truck accident, can be classifi ed as testimonial literature.

Dielectric properties of Sr0.75Ba0.25Nb 2O6 thin films: Bias field, frequency and temperature dependence

Ferroelectric strontium barium niobate solid solutions had received great attention due to their excellent pyroelectric, electrooptic and photorefractive properties. Furthermore, they usually also present very interesting phase transition characteristics. In this work, polycrystalline single phase Sr 0.75 Ba 0.25 Nb 2 O 6 thin films were prepared by a hybrid chemical method and deposited on Pt/Ti/SiO 2 /Si substrates. The temperature dependence of dielectric constant was measured at different frequencies and bias field levels. The presence of two dielectric dispersion regions with relaxor characteristics was observed at distinct temperature ranges, corresponding to the ferro-paraelectric and to a structural phase transition at low temperatures, respectively. A specific dielectric dispersion region, associated with an incommensurate superstructure frequently observed in bulk samples, was not observed in this films probably due to their small grain sizes. © 2002 Taylor & Francis.

Os eventos como estratégia de comunicação nas lutas da cidadania

This study proposes some thinking under a different perspective about the Event Organization Activity. As a directed communication instrument, Events are planned actions, aiming at gathering people with common objectives, for a specific goal, usually under the view of organizations. In this study, some questioning on the relevance of Events at the social movement context is proposed, as they organize themselves through these actions in order to claim and pressure the Government for citizenship rights.

Lutas na Educação Física escolar: relação entre conteúdo, pedagogia e currículo

Vítima de restrição nas aulas de Educação Física, o tema “lutas” foi incluído no Currículo de Educação Física do Estado de São Paulo (CEF-SP) como conteúdo próprio da disciplina. Nesse sentido, o professor precisa ter tido uma vivência de lutas para tratar deste conteúdo? Que saberes são necessários para dar aula de luta na escola? Como se dá a transposição prática das lutas sugeridas no CEF-SP? O objetivo do trabalho é refletir sobre o ensino de lutas nas aulas de Educação Física com o foco nos saberes profissionais docentes. Foram entrevistados três professores: (i) professor especialista em lutas; (ii) professor de Educação Física sem histórico de práticas de lutas (iii) professor de Educação Física com histórico de prática de lutas. Os resultados permitem concluir que não se exige que o professor seja um treinador ou especialista em lutas e artes marciais, no entanto, é necessário estudar, confrontar e reformular seus saberes docentes para ministrar os conteúdos luta em suas aulas.

“PROVINCIALISM, PICKING SIDES AND BIAS: EFFECTS OF GEOGRAPHY ON MEDIA COVERAGE OF CRYSTAL BRIDGES MUSEUM OF AMERICAN ART, 2005-10.”

The development of Crystal Bridges Museum of American Art in Bentonville, Arkansas, by Wal-Mart heiress Alice Walton has prompted diverse coverage from print and online media. This investigation looked at trends in news stories and commentary from 2005-10 to show how the location of a medium affected coverage. Through the author’s own observations and interviews with journalists and other interested parties, several trends emerged. Media outlets outside Arkansas portrayed the museum as trying to plunder the cultural heritage of local communities and relied partly on the museum’s association with Wal-Mart and stereotypes of Arkansas to frame coverage. Arkansas media, faced with limited cooperation from the museum’s public relations apparatus, typically played a cheerleader role, at times overemphasizing the importance of the collection in the art world and showcasing few critical voices in stories about acquisitions and other areas of the museum’s development.

Robust isothermal electric control of exchange bias at room temperature

Voltage-controlled spin electronics is crucial for continued progress in information technology. It aims at reduced power consumption, increased integration density and enhanced functionality where non-volatile memory is combined with highspeed logical processing. Promising spintronic device concepts use the electric control of interface and surface magnetization. From the combination of magnetometry, spin-polarized photoemission spectroscopy, symmetry arguments and first-principles calculations, we show that the (0001) surface of magnetoelectric Cr2O3 has a roughness-insensitive, electrically switchable magnetization. Using a ferromagnetic Pd/Co multilayer deposited on the (0001) surface of a Cr2O3 single crystal, we achieve reversible, room-temperature isothermal switching of the exchange-bias field between positive and negative values by reversing the electric field while maintaining a permanent magnetic field. This effect reflects the switching of the bulk antiferromagnetic domain state and the interface magnetization coupled to it. The switchable exchange bias sets in exactly at the bulk Néel temperature.

Understanding bias in geographic range size estimates

Aim Estimates of geographic range size derived from natural history museum specimens are probably biased for many species. We aim to determine how bias in these estimates relates to range size. Location We conducted computer simulations based on herbarium specimen records from localities ranging from the southern United States to northern Argentina. Methods We used theory on the sampling distribution of the mean and variance to develop working hypotheses about how range size, defined as area of occupancy (AOO), was related to the inter-specific distribution of: (1) mean collection effort per area across the range of a species (MC); (2) variance in collection effort per area across the range of a species (VC); and (3) proportional bias in AOO estimates (PBias: the difference between the expected value of the estimate of AOO and true AOO, divided by true AOO). We tested predictions from these hypotheses using computer simulations based on a dataset of more than 29,000 herbarium specimen records documenting occurrences of 377 plant species in the tribe Bignonieae (Bignoniaceae). Results The working hypotheses predicted that the mean of the inter-specific distribution of MC, VC and PBias were independent of AOO, but that the respective variance and skewness decreased with increasing AOO. Computer simulations supported all but one prediction: the variance of the inter-specific distribution of VC did not decrease with increasing AOO. Main conclusions Our results suggest that, despite an invariant mean, the dispersion and symmetry of the inter-specific distribution of PBias decreases as AOO increases. As AOO increased, range size was less severely underestimated for a large proportion of simulated species. However, as AOO increased, range size estimates having extremely low bias were less common.

Transverse sphericity of primary charged particles in minimum bias proton-proton collisions at root s=0.9, 2.76 and 7 TeV

Measurements of the sphericity of primary charged particles in minimum bias proton-proton collisions at root s = 0.9, 2.76 and 7 TeV with the ALICE detector at the LHC are presented. The observable is measured in the plane perpendicular to the beam direction using primary charged tracks with p(T) > 0.5 GeV/c in vertical bar eta vertical bar < 0.8. The mean sphericity as a function of the charged particle multiplicity at mid-rapidity (N-ch) is reported for events with different p(T) scales ("soft" and "hard") defined by the transverse momentum of the leading particle. In addition, the mean charged particle transverse momentum versus multiplicity is presented for the different event classes, and the sphericity distributions in bins of multiplicity are presented. The data are compared with calculations of standard Monte Carlo event generators. The transverse sphericity is found to grow with multiplicity at all collision energies, with a steeper rise at low N-ch, whereas the event generators show an opposite tendency. The combined study of the sphericity and the mean p(T) with multiplicity indicates that most of the tested event generators produce events with higher multiplicity by generating more back-to-back jets resulting in decreased sphericity (and isotropy). The PYTHIA6 generator with tune PERUGIA-2011 exhibits a noticeable improvement in describing the data, compared to the other tested generators.

Bias and learning in temporal binding: intervals between actions and outcomes are compressed by prior bias

It has consistently been shown that agents judge the intervals between their actions and outcomes as compressed in time, an effect named intentional binding. In the present work, we investigated whether this effect is result of prior bias volunteers have about the timing of the consequences of their actions, or if it is due to learning that occurs during the experimental session. Volunteers made temporal estimates of the interval between their action and target onset (Action conditions), or between two events (No-Action conditions). Our results show that temporal estimates become shorter throughout each experimental block in both conditions. Moreover, we found that observers judged intervals between action and outcomes as shorter even in very early trials of each block. To quantify the decrease of temporal judgments in experimental blocks, exponential functions were fitted to participants’ temporal judgments. The fitted parameters suggest that observers had different prior biases as to intervals between events in which action was involved. These findings suggest that prior bias might play a more important role in this effect than calibration-type learning processes.

A partial dependence factorial analysis to deal with selection bias in observational studis

This thesis presents a creative and practical approach to dealing with the problem of selection bias. Selection bias may be the most important vexing problem in program evaluation or in any line of research that attempts to assert causality. Some of the greatest minds in economics and statistics have scrutinized the problem of selection bias, with the resulting approaches – Rubin’s Potential Outcome Approach(Rosenbaum and Rubin,1983; Rubin, 1991,2001,2004) or Heckman’s Selection model (Heckman, 1979) – being widely accepted and used as the best fixes. These solutions to the bias that arises in particular from self selection are imperfect, and many researchers, when feasible, reserve their strongest causal inference for data from experimental rather than observational studies. The innovative aspect of this thesis is to propose a data transformation that allows measuring and testing in an automatic and multivariate way the presence of selection bias. The approach involves the construction of a multi-dimensional conditional space of the X matrix in which the bias associated with the treatment assignment has been eliminated. Specifically, we propose the use of a partial dependence analysis of the X-space as a tool for investigating the dependence relationship between a set of observable pre-treatment categorical covariates X and a treatment indicator variable T, in order to obtain a measure of bias according to their dependence structure. The measure of selection bias is then expressed in terms of inertia due to the dependence between X and T that has been eliminated. Given the measure of selection bias, we propose a multivariate test of imbalance in order to check if the detected bias is significant, by using the asymptotical distribution of inertia due to T (Estadella et al. 2005) , and by preserving the multivariate nature of data. Further, we propose the use of a clustering procedure as a tool to find groups of comparable units on which estimate local causal effects, and the use of the multivariate test of imbalance as a stopping rule in choosing the best cluster solution set. The method is non parametric, it does not call for modeling the data, based on some underlying theory or assumption about the selection process, but instead it calls for using the existing variability within the data and letting the data to speak. The idea of proposing this multivariate approach to measure selection bias and test balance comes from the consideration that in applied research all aspects of multivariate balance, not represented in the univariate variable- by-variable summaries, are ignored. The first part contains an introduction to evaluation methods as part of public and private decision process and a review of the literature of evaluation methods. The attention is focused on Rubin Potential Outcome Approach, matching methods, and briefly on Heckman’s Selection Model. The second part focuses on some resulting limitations of conventional methods, with particular attention to the problem of how testing in the correct way balancing. The third part contains the original contribution proposed , a simulation study that allows to check the performance of the method for a given dependence setting and an application to a real data set. Finally, we discuss, conclude and explain our future perspectives.

Local home bias: Theory and new empirical evidence from Italy

This thesis examines the literature on local home bias, i.e. investor preference towards geographically nearby stocks, and investigates the role of firm’s visibility, profitability, and opacity in explaining such behavior. While firm’s visibility is expected to proxy for the behavioral root originating such a preference, firm’s profitability and opacity are expected to capture the informational one. I find that less visible, and more profitable and opaque firms, conditionally to the demand, benefit from being headquartered in regions characterized by a scarcity of listed firms (local supply of stocks). Specifically, research estimates suggest that firms headquartered in regions with a poor supply of stocks would be worth i) 11 percent more if non-visible, non-profitable and non-opaque; ii) 16 percent more if profitable; and iii) 28 percent more if both profitable and opaque. Overall, as these features are able to explain most, albeit not all, of the local home bias effect, I reasonably argue and then assess that most of the preference for local is determined by a successful attempt to exploit local information advantage (60 percent), while the rest is determined by a mere (irrational) feeling of familiarity with the local firm (40 percent). Several and significant methodological, theoretical, and practical implications come out.
