O projeto de literacia da informação numa biblioteca da saúde: o caso da Biblioteca da ESTeSL

Introdução – Ao aumento exponencial de informação, sobretudo a científica, não corresponde obrigatoriamente a melhoria de qualidade na pesquisa e no uso da mesma. O conceito de literacia da informação ganha pertinência e destaque, na medida em que abarca competências que permitem reconhecer quando é necessária a informação e de atuar de forma eficiente e efetiva na sua obtenção e utilização. A biblioteca académica assume, neste contexto, o papel de parceiro privilegiado, preparando o momento em que o estudante se sente capaz de produzir e registar novo conhecimento através da escrita. Objectivo – A Biblioteca da ESTeSL reestruturou as sessões desenvolvidas desde o ano lectivo 2002/2003 e deu início a um projecto mais formal denominado «Saber usar a informação de forma eficiente e eficaz». Objectivos: a) promover a melhoria da qualidade dos trabalhos académicos e científicos; b) contribuir para a diminuição do risco de plágio; c) aumentar a confiança dos estudantes nas suas capacidades de utilização dos recursos de informação; d) incentivar uma participação mais ativa em sala de aulas; e) colaborar para a integração dos conteúdos pedagógicos e das várias fontes de informação. Método – Dinamizaram-se várias sessões de formação de curta duração, versando diferentes temas associados à literacia de informação, designadamente: 1) Pesquisa de informação com sessões dedicadas à MEDLINE, RCAAP, SciELO, B-ON e Scopus; 2) Factor de impacto das revistas científicas: Journal Citation Reports e SciMAGO; 3) Como fazer um resumo científico?; 4) Como estruturar o trabalho científico?; 5) Como fazer uma apresentação oral?; 6) Como evitar o plágio?; 7) Referenciação bibliográfica usando a norma de Vancouver; 8) Utilização de gestores de referências bibliográficas: ZOTERO (primeira abordagem para os estudantes de 1º ano de licenciatura) e a gestão de referências e rede académica de informação com o MENDELEY (direcionado para estudantes finalistas, mestrandos, docentes e investigadores). O projecto foi apresentado à comunidade académica no site da ESTeSL; cada sessão foi divulgada individualmente no site e por email. Em 2015, a divulgação investiu na nova página da Biblioteca (https://estesl.biblio.ipl.pt/), que alojava informações e recursos abordados nas formações. As inscrições eram feitas por email, sem custos associados ou limite mínimo ou máximo de sessões para participar. Resultados – Em 2014 registaram-se 87 inscrições. Constatou-se a presença de, pelo menos, um participante em cada sessão de formação. Em 2015, o total de inscrições foi de 190. Foram reagendadas novas sessões a pedido dos estudantes cujos horários não eram compatíveis com os inicialmente agendados. Foram então organizados dois dias de formação seguida (cerca de 4h em cada dia) com conteúdos selecionados pelos estudantes. Registou-se, nestas sessões, a presença contante de cerca de 30 estudantes em sala. No total, as sessões da literacia da informação contaram com estudantes de licenciatura de todos os anos, estudantes de mestrado, docentes e investigadores (internos e externos à ESTeSL). Conclusões – Constata-se a necessidade de introdução de novos conteúdos no projeto de literacia da informação. O tempo, os conteúdos e o interesse demonstrado por aqueles que dele usufruíram evidenciam que este é um projeto que está a ganhar o seu espaço na comunidade da ESTeSL e que a literacia da informação contribui de forma efetiva para a construção e para a produção de conhecimento no meio académico.

A saúde fora de portas: o projeto de literacia da informação da ESTeSL

Introdução – A pesquisa de informação realizada pelos estudantes de ensino superior em recursos eletrónicos não corresponde necessariamente ao domínio de competências de pesquisa, análise, avaliação, seleção e bom uso da informação recuperada. O conceito de literacia da informação ganha pertinência e destaque, na medida em que abarca competências que permitem reconhecer quando é necessária a informação e de atuar de forma eficiente e efetiva na sua obtenção e utilização. Objetivo – A meta da Escola Superior de Tecnologia da Saúde de Lisboa (ESTeSL) foi a formação em competências de literacia da informação, fora da ESTeSL, de estudantes, professores e investigadores. Métodos – A formação foi integrada em projetos nacionais e internacionais, dependendo dos públicos-alvo, das temáticas, dos conteúdos, da carga horária e da solicitação da instituição parceira. A Fundação Calouste Gulbenkian foi o promotor financeiro privilegiado. Resultados – Decorreram várias intervenções em território nacional e internacional. Em 2010, em Angola, no Instituto Médio de Saúde do Bengo, formação de 10 bibliotecários sobre a construção e a gestão de uma biblioteca de saúde e introdução à literacia da informação (35h). Em 2014, decorrente do ERASMUS Intensive Programme, o OPTIMAX (Radiation Dose and Image Quality Optimisation in Medical Imaging) para 40 professores e estudantes de radiologia (oriundos de Portugal, Reino Unido, Noruega, Países Baixos e Suíça) sobre metodologia e pesquisa de informação na MEDLINE e na Web of Science e sobre o Mendeley, enquanto gestor de referências (4h). Os trabalhos finais deste curso foram publicados em formato de ebook (http://usir.salford.ac.uk/34439/1/Final%20complete%20version.pdf), cuja revisão editorial foi da responsabilidade dos bibliotecários. Ao longo de 2014, na Escola Superior de Educação, Escola Superior de Dança, Instituto Politécnico de Setúbal e Faculdade de Medicina de Lisboa e, ao longo de 2015, na Universidade Aberta, Escola Superior de Comunicação Social, Instituto Egas Moniz, Faculdade de Letras de Lisboa e Centro de Linguística da Universidade de Lisboa foram desenhados conteúdos sobre o uso do ZOTERO e do Mendeley para a gestão de referências bibliográficas e sobre uma nova forma de fazer investigação. Cada uma destas sessões (2,5h) envolveu cerca de 25 estudantes finalistas, mestrandos e professores. Em 2015, em Moçambique, no Instituto Superior de Ciências da Saúde, decorreu a formação de 5 bibliotecários e 46 estudantes e professores (70h). Os conteúdos ministrados foram: 1) gestão e organização de uma biblioteca de saúde (para bibliotecários); 2) literacia da informação: pesquisa de informação na MEDLINE, SciELO e RCAAP, gestores de referências e como evitar o plágio (para bibliotecários e estudantes finalistas de radiologia). A carga horária destinada aos estudantes incluiu a tutoria das monografias de licenciatura, em colaboração com mais duas professoras do projeto. Para 2016 está agendada formação noutras instituições de ensino superior nacionais. Perspetiva-se, ainda, formação similar em Timor-Leste, cujos conteúdos, datas e carga horária estão por agendar. Conclusões – Destas iniciativas beneficia a instituição (pela visibilidade), os bibliotecários (pelo evidenciar de competências) e os estudantes, professores e investigadores (pelo ganho de novas competências e pela autonomia adquirida). O projeto de literacia da informação da ESTeSL tem contribuído de forma efetiva para a construção e para a produção de conhecimento no meio académico, nacional e internacional, sendo a biblioteca o parceiro privilegiado nesta cultura de colaboração.

Group decision making for selection of an information system in a business context

The main objective of this work is to report on the development of a multi-criteria methodology to support the assessment and selection of an Information System (IS) framework in a business context. The objective is to select a technological partner that provides the engine to be the basis for the development of a customized application for shrinkage reduction on the supply chains management. Furthermore, the proposed methodology di ers from most of the ones previously proposed in the sense that 1) it provides the decision makers with a set of pre-defined criteria along with their description and suggestions on how to measure them and 2)it uses a continuous scale with two reference levels and thus no normalization of the valuations is required. The methodology here proposed is has been designed to be easy to understand and use, without a specific support of a decision making analyst.

Media Brokerage: Agent-Based SLA Negotiation

Media content personalisation is a major challenge involving viewers as well as media content producer and distributor businesses. The goal is to provide viewers with media items aligned with their interests. Producers and distributors engage in item negotiations to establish the corresponding service level agreements (SLA). In order to address automated partner lookup and item SLA negotiation, this paper proposes the MultiMedia Brokerage (MMB) platform, which is a multiagent system that negotiates SLA regarding media items on behalf of media content producer and distributor businesses. The MMB platform is structured in four service layers: interface, agreement management, business modelling and market. In this context, there are: (i) brokerage SLA (bSLA), which are established between individual businesses and the platform regarding the provision of brokerage services; and (ii) item SLA (iSLA), which are established between producer and distributor businesses about the provision of media items. In particular, this paper describes the negotiation, establishment and enforcement of bSLA and iSLA, which occurs at the agreement and negotiation layers, respectively. The platform adopts a pay-per-use business model where the bSLA define the general conditions that apply to the related iSLA. To illustrate this process, we present a case study describing the negotiation of a bSLA instance and several related iSLA instances. The latter correspond to the negotiation of the Electronic Program Guide (EPG) for a specific end viewer.

Reflections on the legal framework for relations between cooperatives and subsidiaries.

In the light of Portuguese legal system, cooperative enterprises may include an enterprise carried out by a subsidiary, provided they conform to certain requirements. The aim of this paper is to reflect on the issue of the legal framework of the relationship between the cooperative and the subsidiary. There are several problems to be addressed in this paper: (i) How to qualify such a relationship since corresponding to mere investments made by the cooperative? Should it be classified as non-member cooperative transactions or as extraordinary activities? (ii) How to qualify such a relationship when related to the development of preparatory or complementary activities for the economic activity developed between the cooperative and its members? May we speak, in this situation, of a concept of “indirect mutuality”, as provided in other legal systems? (iii) How should we classify and what is the regime of the economic results from the activity developed by the subsidiary? We will conclude, advocating: (i) That the cooperative enterprise may include an enterprise carried out by a subsidiary if this is deemed necessary to satisfy the interests of the members; (ii) The inadmissibility of the concept of “indirect mutuality”; (iii) The inadequacy of qualifying the legal relationship between the cooperative partner (iv) The application, to the economic results coming from the activity developed by the subsidiary, of the regime provided for in the Portuguese Cooperative Code to the results from non-member cooperative transactions; (v) The economic results coming from the activity developed by the subsidiary cannot be appropriated by individual co-operators members, and so should be allocated to indivisible reserves.

Brokerage Platform for Media Content Recommendation

Near real time media content personalisation is nowadays a major challenge involving media content sources, distributors and viewers. This paper describes an approach to seamless recommendation, negotiation and transaction of personalised media content. It adopts an integrated view of the problem by proposing, on the business-to-business (B2B) side, a brokerage platform to negotiate the media items on behalf of the media content distributors and sources, providing viewers, on the business-to-consumer (B2C) side, with a personalised electronic programme guide (EPG) containing the set of recommended items after negotiation. In this setup, when a viewer connects, the distributor looks up and invites sources to negotiate the contents of the viewer personal EPG. The proposed multi-agent brokerage platform is structured in four layers, modelling the registration, service agreement, partner lookup, invitation as well as item recommendation, negotiation and transaction stages of the B2B processes. The recommendation service is a rule-based switch hybrid filter, including six collaborative and two content-based filters. The rule-based system selects, at runtime, the filter(s) to apply as well as the final set of recommendations to present. The filter selection is based on the data available, ranging from the history of items watched to the ratings and/or tags assigned to the items by the viewer. Additionally, this module implements (i) a novel item stereotype to represent newly arrived items, (ii) a standard user stereotype for new users, (iii) a novel passive user tag cloud stereotype for socially passive users, and (iv) a new content-based filter named the collinearity and proximity similarity (CPS). At the end of the paper, we present off-line results and a case study describing how the recommendation service works. The proposed system provides, to our knowledge, an excellent holistic solution to the problem of recommending multimedia contents.

Detection of HIV and HCV RNA in semen from Brazilian coinfected men using multiplex PCR before and after semen washing

INTRODUCTION: Prolonged survival of patients under HAART has resulted in new demands for assisted reproductive technologies. HIV serodiscordant couples wish to make use of assisted reproduction techniques in order to avoid viral transmission to the partner or to the newborn. It is therefore essential to test the effectiveness of techniques aimed at reducing HIV and HCV loads in infected semen using molecular biology tests. METHODS: After seminal analysis, semen samples from 20 coinfected patients were submitted to cell fractioning and isolation of motile spermatozoa by density gradient centrifugation and swim-up. HIV and HCV RNA detection tests were performed with RNA obtained from sperm, seminal plasma and total semen. RESULTS: In pre-washing semen, HIV RNA was detected in 100% of total semen samples, whereas HCV RNA was concomitantly amplified in only one specimen. Neither HIV nor HCV were detected either in the swim-up or in the post-washing semen fractions. CONCLUSIONS: Reduction of HIV and/or HCV shedding in semen by density gradient centrifugation followed by swim-up is an efficient method. These findings lead us to believe that, although semen is rarely found to contain HCV, semen processing is highly beneficial for HIV/HCV coinfected individuals.

Working hours and earnings: are mates’ answers coherent?

As surveys about time allocation among couples are extremely expensive, one way of reducing costs could be to query only one member of the coupler with the same set of questions about him/her and about his/her partner. In this paper we show that after carrying out a survey in this way, the responses given by one partner do not always fit the same econometric model as those obtained from the other.

HIV Voluntary Testing among Portuguese Women Attending Family Planning Clinics: Implications for HIV Prevention Education and Testing

Objectives: The aim of this article is to analyze the factors associated with HIV testing among 767 sexually active women. Methods: Participants were administered several self-report questionnaires that assessed behavioral and psychosocial measures. Results: Overall, 59.8% of the participants reported ever having tested for HIV. Results show that higher levels of education, being pregnant or having been pregnant, concern about AIDS, AIDS knowledge, self-efficacy in condom negotiation and perception of no risk in partner significantly predicted the likelihood of testing among women. Attending the mass was negatively associated with HIV testing. Conclusions: These findings provide information that can be used in the development of a focused gender sensitive HIV prevention program to increase HIV testing.

Predictors of consistent condom use among Portuguese women attending family planning clinics

Women account for 30% of all AIDS cases reported to the Health Ministry in Portugal and most infections are acquired through unprotected heterosexual sex with infected partners. This study analyzed socio-demographic and psychosocial predictors of consistent condom use and the role of education as a moderator variable among Portuguese women attending family planning clinics. A cross-sectional study using interviewer-administered fully structured questionnaires was conducted among 767 sexually active women (ages 18–65). Logistic regression analyses were used to explore the association between consistent condom use and the predictor variables. Overall, 78.7% of the women were inconsistent condom users. The results showed that consistent condom use was predicted by marital status (being not married), having greater perceptions of condom negotiation self-efficacy, having preparatory safer sexual behaviors, and not using condoms only when practicing abstinence. Living with a partner and having lack of risk perception significantly predicted inconsistent condom use. Less educated women were less likely to use condoms even when they perceive being at risk. The full model explained 53% of the variance in consistent condom use. This study emphasizes the need for implementing effective prevention interventions in this population showing the importance of taking education into consideration.
