RESUMO: As mulheres presas encontram-se num sistema essencialmente dirigido por e concebido para homens. As mulheres que entram na prisão geralmente vêm de ambientes marginalizados e desfavorecidos e muitas vezes têm histórias de violência e abuso físico e sexual. As mulheres presas são um grupo particularmente vulnerável, uma vez que dentro do sistema prisional as suas necessidades de saúde e higiene são muitas vezes negligenciadas. O primeiro passo para o desenvolvimento de programas e práticas sensíveis ao género é compreender as características das mulheres delinquentes e definir fatores de vida específicos que contribuem para a formação do comportamento criminoso de mulheres. Em junho de 2012 foi realizada uma investigação na única prisão feminina da Geórgia, para estudar as necessidades mentais e psicossociais das mulheres presas. O objetivo da pesquisa foi o desenvolvimento de programas de apoio pertinentes para a reabilitação, ressocialização e reintegração, e a elaboração de recomendações práticas para a gestão das prisões. Foi desenvolvido um instrumento de pesquisa (inquérito) com uma fundamentação conceptual baseada em quatro principais teorias: Teoria dos Caminhos (Pathways Theory), teoria do desenvolvimento psicológico da mulher (Theory of Women’s Psychological Development), Trauma e Teorias da Dependência (Trauma and Addiction Theories). Foram inquiridas 120 mulheres presas. Os resultados deste estudo mostram que muitas das necessidades das mulheres presas são diferentes das dos homens e requerem estratégias adaptadas às suas características e situações psicossociais específicas. A maioria das mulheres encarceradas é jovem, enérgica, pode trabalhar, tem profissão e família. As presas sofrem de problemas psicológicos e muitas vezes são rejeitadas pelas suas famílias. Uma parte substancial das mulheres presas tem múltiplos problemas de saúde física e mental. A maioria delas tem filhos e sofre com o facto das crianças estarem a crescer longe da mãe. Com base nos resultados desta investigação é possível elaborar um contexto promotor do planeamento e desenvolvimento de serviços com um enfoque de género na prisão. Na perspetiva de longo prazo, o conhecimento das necessidades básicas e a introdução de programas e serviços com necessidades específicas pertinentes irá beneficiar as presas e as suas famílias, e melhorar a eficácia do sistema de justiça criminal.----------ABSTRACT: Female inmates find themselves in a system essentially run by men for men. Women who enter prison usually come from marginalized and disadvantaged backgrounds and are often characterized by histories of violence, physical and sexual abuse. Female prisoners constitute an especially vulnerable group given their specific health and hygienic needs within the system are often neglected. The first step in developing gender-sensitive program and practice is to understand female offenders’ characteristics and the specific life factors that shape women’s patterns of offending. In June 2012 a research was carried out in the Georgian only female prison facility to assess the mental and psychosocial needs of women prisoners, aiming to develop effective support programs for their rehabilitation, re-socialization and reintegration, as well as to elaborate new recommendations concerning prison management. A survey instrument (questionnaire) was developed within a theoretical framework based on four fundamental theories: Pathways Theory, Theory of Women’s Psychological Development and Trauma and Addiction Theories. Sample size was defined to be 120 surveyed persons. The study showed that needs of incarcerated women were different from those of men, thus requiring approaches tailored to their specific psychosocial characteristics and situations. The basic population of imprisoned women consisted of young, energetic, working-age females, most often with a professional qualification. Female prisoners suffered from psychological problems and are were more likely to be rejected by their families. Most of them had children and suffered that the children were growing without mothers. A substantial proportion of women offenders had multiple physical and mental health problems. Based on the study findings a conceptual framework can be elaborated towards planning and developing gender-sensitive services in prison. In the long-term perspective, acknowledgement of baseline needs and introduction of the relevant needs-specific programs and services may benefit women prisoners as well as their families, improving the effectiveness of the criminal justice system.

Prostate cancer (PCa) is the most common form of cancer in men, in Europe (World Health Organization data). The most recent statistics, in Portuguese territory, confirm this scenario, which states that about 50% of Portuguese men may suffer from prostate cancer and 15% of these will die from this condition. Its early detection is therefore fundamental. This is currently being done by Prostate Specific Antigen (PSA) screening in urine but false positive and negative results are quite often obtained and many patients are sent to unnecessary biopsy procedures. This early detection protocol may be improved, by the development of point-of-care cancer detection devices, not only to PSA but also to other biomarkers recently identified. Thus, the present work aims to screen several biomarkers in cultured human prostate cell lines, serum and urine samples, developing low cost sensors based on new synthetic biomaterials. Biomarkers considered in this study are the following: prostate specific antigen (PSA), annexin A3 (ANXA3), microseminoprotein-beta (MSMB) and sarcosine (SAR). The biomarker recognition may occurs by means of molecularly imprinted polymers (MIP), which are a kind of plastic antibodies, and enzymatic approaches. The growth of a rigid polymer, chemically stable, using the biomarker as a template allows the synthesis of the plastic antibody. MIPs show high sensitivity/selectivity and present much longer stability and much lower price than natural antibodies. This nanostructured material was prepared on a carbon solid. The interaction between the biomarker and the sensing-material produces electrical signals generating quantitative or semi-quantitative data. These devices allow inexpensive and portable detection in point-of-care testing.

In a male dominant political world, the cases of female leadership are still a novelty. Looking at the episodes where a woman was head of state or government, the impact on attitudes and perceptions toward gender equality is evaluated. By instrumenting the presence of a female in government with the proportion of female seats in parliament, the results seem to suggest that individuals, when exposed to a woman as an executive political leader, report a higher tendency to agree with statements of gender discrimination.

Courtship is a behavior that allows the display of fitness of one sex to the other and gates possible subsequent mating. This behavior is crucial for reproduction and has strong innate components in all animals. Courtship in Drosophila melanogaster consists of a series of highly stereotyped actions that the male performs towards the female. He sings with vibrations of the wings, touches and licks her abdomen, while she evaluates the information presented to her.(...)
