Entre Aracne e Atena: professoras em situação de violência doméstica

Este estudo tem como tema a violência doméstica contra professoras e toma como objeto os registros sobre esse fato presentes em Inquéritos Policiais da Delegacia de Atendimento à Mulher de Santarém-PA. A questão central da pesquisa consiste em problematizar: quais articulações entre a condição de violentada e o status profissional de professora são apresentadas no processo de denúncia, via inquérito policial, por professoras em situação de violência doméstica no município de Santarém? A partir dessa indagação central o objetivo geral da pesquisa volta-se para analisar as articulações entre a condição de violentada e o status profissional de professora presentes nos inquéritos policiais, articulado com a investigação das confluências entre as discussões sobre as relações de gênero, a violência doméstica e os direitos humanos das mulheres e a compreensão das formas de atravessamento entre os marcadores sociais das professoras em situação de violência doméstica. O tratamento metodológico foi pautado em um estudo qualitativo que se vale da pesquisa documental, por meio da análise de conteúdo dos Inquéritos Policiais da DEAM de Santarém, documentos estes que registram não só a ocorrência da violência como também o contexto em que ocorreram os atravessamentos dos diferentes marcadores sociais assumidos pelos sujeitos, autores das agressões e agredidas e suas intersecções. O marco teórico da pesquisa está pautado na perspectiva relacional que busca compreender a violência contra as mulheres resultantes das redes de relações de poder entre homens e mulheres e entre estes e os marcadores sociais que assumem. As análises conclusivas evidenciam que as tramas da violência doméstica contra as mulheres são complexas e marcadas por questões, tais como: a persistência na submissão à violência doméstica das docentes embora independam economicamente do agressor; a diferença geracional entre as docentes e os autores das agressões é marcada por homens mais jovens versus mulheres maduras, em processo de envelhecimento; o baixo nível de escolaridade dos agressores e o baixo prestígio da ocupação que desenvolvem em relação ao nível de escolaridade e posição social da profissão das docentes agredidas que possuem profissão definida, de natureza intelectual e reconhecida socialmente; as denúncias contra os autores das agressões só ocorreram após os motivos extremos de ameaças de morte e exposição pública da violência em uma profissão de natureza pública, a de professora; que o registro da ocorrência concretiza a alternância de poder nas relações de gênero e da própria violência doméstica, visto que na dinâmica da circulação de poder com os autores das agressões, as professoras agredidas reconheceram-se também como detentoras de poder, avançando da condição de vítimas para a de protagonistas; que na situação de violentadas, as professoras, foram capazes de perceber fios invisíveis naturalizados na teia da violência doméstica, partindo para o enfrentamento público, a denúncia.

Estudo comportamental de Besourão-de-rabo-branco Phaethornis superciliosus (Aves, Trochilidae) no Parque Ecológico de Gunma

A comunicação acústica em beija-flores durante muito tempo foi negligenciada em função da coloração conspícua que representa uma sofisticada comunicação visual da maioria dos representantes deste grupo. Entretanto, estudos recentes constataram que há indícios de aprendizagem vocal em algumas espécies de Trochilidae. O presente estudo aborda o comportamento vocal do beija-flor Phaethornis superciliosus, espécie abundante na região amazônica. Esta espécie apresenta como sistema de acasalamento a formação em arena, que consiste na agregação de machos em um pequeno território, onde se exibem para outros machos e fêmeas, com o intuito de atrair estas últimas para acasalar. O objetivo geral deste trabalho foi analisar o comportamento vocal de P. superciliosus dispostos em seis arenas no Parque Ecológico de Gunma, Santa Bárbara do Pará, 50 km ao norte de Belém, considerando a emissão e estrutura física do canto, seu repertório, a frequência de emissão ao longo do dia e do ano e a dinâmica das arenas. Verificamos que a população estudada apresenta um repertório vocal composto de duas notas que são emitidas de maneira alternada. Os cantos dos indivíduos analisados apresentaram diferenças significativas entre si considerando os parâmetros físicos do som (frequências máxima e mínima, duração e intervalo entre as notas e o ritmo de emissão das notas). Esta diferenciação inter-individual pode estar relacionada à seleção sexual, na qual o canto pode permitir o reconhecimento individual, sua posição social e seu desempenho para a atração das fêmeas. Constatamos que a atividade vocal é mais intensa no segundo semestre, entre junho e novembro, período que provavelmente corresponde à estação reprodutiva. Realizamos testes de playback, que consistem em reproduzir um som previamente gravado e registrar a resposta provocada em uma das arenas em dois pontos distintos, simulando a entrada de outro indivíduo. Constatamos que o som emitido em resposta ao teste diferiu significativamente do canto espontâneo em todos os parâmetros físicos analisados. A resposta ao playback mostra que houve uma redução na faixa de frequência com que o canto foi emitido e o ritmo de emissão de notas mais rápido. Tais características do canto podem estarrelacionadas a um comportamento mais agressivo. As arenas são formadas emáreas de borda e sempre próximas a igarapés, com o tamanho da área variando entre 86m² e 14m², compostas de dois a quatro indivíduos distantes de 7m a 72m entre si. Nossos resultados mostraram que a organização social da arena deve ser melhor compreendida através de estudos mais detalhados sobre o possível significado que as diferenças individuais no canto podem representar para o estabelecimento da posição hierárquica dos indivíduos nas arenas.

Den flygande maran : En studie om åtta narkotikabrukande kvinnor i Stockholm

Between April 1997 and November 1999, I followed eight socially excluded female drug users in an attempt to describe their lives and living conditions. The study employs an ethnographic approach with the focus being directed at the specific woman and her life in relation to the social context where this life is lived. The study’s objective has been to describe the lives and living conditions of the eight drug-using women, as well as the extent of the opportunities available to them, as being determined by mechanisms of social exclusion. Their lives are understood on the basis of a feminist and social constructionist perspective where perceptions of ‘the drug-abusing woman’ are regarded as the result of constructions of gender and deviance. The theoretical perspectives proceeds from the idea that one is not born a woman but rather becomes one. The fundamental idea is that women become women by means of processes of femininisation, in the context of which certain ways of interpreting and presenting oneself as a woman are regarded as good and others as bad. Our images of ‘the female drug addict’ are based on how we define and interpret deviance and on the cultural and social thought and behaviour patterns we ascribe to people on the basis of bodily differences. It is images of ‘the good woman’ that defines what we regard as characteristic of ‘the bad woman’ and vice versa. The findings are organised into three main topics: femininity, living conditions and social control. The main findings are: The women described themselves as women by relating to normative messages about how women “are and should be”, and their drug use constituted a means of coping with life from their social position. Their life revolved to a large extent around money via a constant struggle to find enough to cover the rent, food and other basic necessities. And finally, how the women’s relations to societal institutions were formed by their social position as ‘female drug addicts’ and how the asymmetry of these relations produced certain fixed patterns of action for the parties involved.

Towards a Variety of Family Models: Economic Contributions of Spouses and Family Power

In Western societies the increase in female employment (especially among married women) is seen as having brought about the crisis of the traditional model of the family, reinforcing the position of the "modern" model - the egalitarian family with two working spouses and a "dual-career" family. In contrast, the transitional situation in the post-communist countries during the 1990s is producing a crisis of the family with two working spouses (the basic type of the communist period) and leading to new power relations within the family. While the growth of dual-earner households in this century has implied modification of family models towards greater symmetry of responsibility for breadwinning and homemaking, there is considerable evidence that women's increased employment does not necessarily lead to a more egalitarian approach to gender roles within the family. The group set out to investigate the economic situation of families and economic power within the fame as a crucial factor in the transformation of families with two working spouses in order to reveal the specific patterns of gender contracts and power relations within the family that are emerging in response to the current political and economic transformation. They opted for a comparative approach, selecting the Czech Republic as a country where the very similar tendencies of a few years ago (almost 100% of women employed and the family as a realm of considerable private freedom where both women's and men's gender identities and the traditional distribution of family responsibilities were largely preserved) are combined with a very different experience in terms of economic inequalities during the 1990s to that of Russia. In the first stage of the study they surveyed 300 married couples (150 in each country) on the question of breadwinning. They then carried out in-depth interviews with 10 couples from each country (selected from among the educated layers of the population), focusing on the process of the social construction of gender, using breadwinning and homemaking as gender boundaries which distinguish men from women. By analysing changes in social position and the type of interpersonal interaction of spouses they distinguished two main types of family contracts: the neo-traditional "communal sharing" (with male breadwinner, traditional distribution of family chores and negotiated family power) and the modern one based on negotiated agreement. The most important pre-conditions of husband-wife agreement about breadwinning seemed to imply their overall gender ideology rather than the economic and/or family circumstances. In general, wives were more likely to express egalitarian views, supporting the blurring or even elimination of many gender boundaries. Husbands, on the other hand, more often gave responses calling for the continued maintenance of gender boundaries. The analysis showed that breadwinning is still an important gender boundary in these cultures, one that is assumed unless it is explicitly questioned and that is seen as part of what makes a man a "real man". The majority of respondents seemed to be committed to egalitarian ideology on gender roles and the distribution of family tasks, including decision making, but this is contradicted by the persistent idea of the husband as the breadwinner. This contradiction is more characteristic of the Russian situation than of the Czech. The quantitative study showed a difference in prevailing family models between the two countries, with a clearer shift towards the traditional family contract in the Russian case. The Czechs were more likely to consider their partnerships as based on negotiated agreement, while the Russians saw theirs as based on egalitarian contract, in both cases seeing this as the norm. The majority of couples said they felt satisfied with their marriage, although in both countries wives seemed to be less satisfied. There was however a difference in the issues that aroused dissatisfaction, with Czech women being more sensitive to issues such as self-realisation, personal independence, understanding and recognition in the family, and Russians to issues of love, understanding and recognition. The most disputed area for the majority of families was chores in the home, presumably because in many families both husband and wife were working hard outside the home and because a number of partners had differing views as to the ideal distribution of chores within the family. The distribution of power in the family seems to be linked to the level of well being. The analysis showed that in the dominant democratic model there is still an inverse connection between family leadership and well being: the more prominent the wife's position as head of the family is, the lower the level of family income. This may reflect both the husband's refusal to play the leading role in the family and even his rejection of any involvement in family issues in such a family. The qualitative research revealed that both men and women see the breadwinning role to be an essential part of masculine identity, a role which the female partner would take on temporarily to assist the male but not permanently since this would threaten the gender boundaries and the man's identity. At the same time, few breadwinners expressed a sense of job satisfaction and all considered their choice as imposed on them by the circumstances (i.e. having a family in difficult times). The group feel that family orientation and some loss of personal involvement in their profession is partly reflected in the fact that many of the men felt more comfortable and self-confident at home than at work. Women's work, on the other hand, was largely seen as a source of personal and self-realisation and social life. Eight out of ten of the Russian women interviewed were employed, although only two on a full-time basis, but none saw their jobs as adding substantially to the family budget. Both partners see the most important factor as the wife's wish to work or stay at home, and do not think it wise for the wife to work at the expense of her part of the "family contract", although husbands from the "egalitarian" relationships expressed more willingness to compromise. The analysis showed clearly that wives and husbands did not construct gender boundaries in isolation, with the interviews providing clear evidence of negotiation. At the same time, husbands' interpretations of their wives' employment were less susceptible to the influence of negotiation than were their gender attitudes and norms about breadwinning. One of the most interesting aspects of the spouses' negotiations was the extent to which they disagreed about what they seemed to have agreed upon. Most disagreements about the breadwinning boundaries, however, were over norms and were settled by changes in norms rather than in behavioural interpretation. Changes in norms were often a form of peace offering or were in response in changes in circumstances. The study did show, however, that many of the efforts at cooperation and compensation were more symbolic than real and the group found the plasticity of expressed gender ideology to be one of the most striking findings of their work. They conclude that the shift towards more traditional gednder distributions of incomes and domestic chores does not automatically mean the reestablishment of a patriarchal model of family power. On the contrary, it seems to be a compromise formation, relatively unstable, temporary and containing self-defeating forces as the split between the personal and professional value of work and its social value expressed in a money equivalent cannot be maintained for generations.

Equality and Diversity in the Dutch Welfare State

Under the Constitution, the equality principle is very important in the Netherlands. This article argues that there is little evidence for equal citizenship in the Netherlands. There is anti-discrimination legislation in the Netherlands, but it is not very robust. The core argument in this article is that the equality principle must be supplemented by the diversity principle. Diversity is multi-dimensional and can refer to religion, philosophy of life, political persuasion, race (ethnicity), gender, nationality, sexual orientation, age, disability and chronic illness. In this paper multi-culturalism and disability are taken into account and we make a comparison of the social position of disabled people and people from ethnic minorities. Policies on diversity are needed to arrive at diverse citizenship in a varied society. This implies that a distinction has to be made between political citizenship and cultural citizenship. The former has to do with equality, and the latter with diversity.

Individual and spousal education, mortality and life expectancy in Switzerland: a national cohort study.

BACKGROUND Household measures of socioeconomic position may better account for the shared nature of material resources, lifestyle, and social position of cohabiting persons, but household measures of education are rarely used. We aimed to evaluate the association of combined educational attainment of married couples on mortality and life expectancy in Switzerland. METHODS The study included 3 496 163 ever-married persons aged ≥30 years. The 2000 census was linked to mortality records through 2008. Mortality by combined educational attainment was assessed by gender-age-specific HRs, with 95% CIs from adjusted models, life expectancy was derived using abridged life tables. RESULTS Having a less educated partner was associated with increased mortality. For example, the HR comparing men aged 50-64 years with tertiary education married to women with tertiary education to men with compulsory education married to women with compulsory education was 2.05 (1.92-2.18). The estimated remaining life expectancy in tertiary educated men aged 30 years married to women with tertiary education was 4.6 years longer than in men with compulsory education married to women with compulsory education. The gradient based on individual education was less steep: the HR comparing men aged 50-64 years with tertiary education with men with compulsory education was 1.74 (1.67-1.81). CONCLUSIONS Using individual educational attainment of married persons is common in epidemiological research, but may underestimate the combined effect of education on mortality and life expectancy. These findings are relevant to epidemiologic studies examining socio-demographic characteristics or aiming to adjust results for these characteristics.

Scientists’ situated knowledge: Strong objectivity in transdisciplinarity

Although transdisciplinary research has started addressing important epistemological challenges, as evidenced by the discussion about ‘mode 2’ knowledge production, its relation with postulations of ‘scientific objectivity’ is not yet well clarified. A common way of dealing with the epistemological challenge of situated knowledge production, as proposed by transdisciplinarity, is to point to the fundamental aspect of reflexivity. But reflexivity also includes being aware that power and control over the object is derived from the social position of researchers, an issue not often explicitly discussed in transdisciplinary research. Reflexivity thus represents an important but insufficient principle for guaranteeing appropriate levels of self-reflection within a process of knowledge coproduction. We therefore hypothesize that transdisciplinary research could greatly benefit from feminist scientific tradition, in particular the insights of standpoint theory and the concept of ‘strong objectivity’. We analyse, and reflect upon, how a recent transdisciplinary research initiative – conducted together with civil society organizations in (CSOs) in six countries: Bangladesh, Bolivia, Brazil, Burkina Faso, Ecuador and India – has benefited from the use of ‘strong objectivity’. We analyse how the social position of all stakeholders, including ourselves as the scientific actors in this initiative, influence the process and conditions of transdisciplinary knowledge co-production, and we discuss how power and control by scientists affects the process and conditions of interaction. Thereby we argue for the necessity of explicitly assuming sides in contested contexts for reaching objectivity in transdisciplinary research.

From school to work : Muslim youths' education and employment strategies in a community in Uttar Pradesh, India

India's Muslim community, which accounts for 14.4 percent of India’s vast population and is thus the largest of all religious minorities, has been the subject of considerable development discourse as Muslims have the lowest level of educational attainment and standard of living among socio-religious groups in the country. This study addresses the meaning of education and career opportunities for Muslim youths in relation to their educational credentials and social position in the hierarchy of Muslim class and caste groups, with particular reference to a community in Uttar Pradesh. The author contends that the career opportunities, possibilities, and strategies of Muslim youths in Indian society depend on multiple factors: social hierarchy, opportunities to utilize economic resources, social networks, cultural capital, and the wider structural disparities within which the Muslims are situated and wherein they question the value of higher education in gaining them admission to socially recognized and established employment sectors.
