A personagem feminina nos romances de Maria Peregrina de Sousa: ambiguidades e dualidades

Pesquisar sobre escritoras portuguesas do século XIX não é tarefa das mais simples. A barreira maior é a escassez de fontes, que se deve, principalmente, ao papel que cabia à mulher na sociedade de oitocentos. Sem direitos políticos e restrita ao espaço privado, deveria estar sempre sob a dependência de um homem. Ao penetrar num espaço que não era o seu, é compreensível que as mulheres que ousaram se afirmar como escritoras o tenham feito a princípio sob o signo do anonimato. É o caso de Maria Peregrina de Sousa (1809-1894). Teve participação profunda nos periódicos literários da época, nos quais publicou romances, poemas e contos populares, utilizando pseudônimos como Uma obscura portuense, Mariposa ou suas iniciais, D. M. P. Por meio de um diálogo com a História, estudamos as obras Retalho do mundo (1859), Maria Isabel (1866), Henriqueta: romance original (1876) e Pepa (1846), da qual também fizemos a edição. Nosso objetivo é investigar, nesses textos, como o discurso do senso comum ora se confirma às vezes, ora é desestabilizado, e como algumas personagens poderiam contornar os interditos sociais. Ao trazer essa obscura portuense à luz, pretendemos também refletir sobre como uma autora pensava a sua realidade e qual o reflexo disso na sua produção literária.

Non-anonymous ballot aggregation: an axiomatic generalization of Approval Voting

We study axiomatically situations in which the society agrees to treat voters with different characteristics distinctly. In this setting, we propose a set of intuitive axioms and show that they jointly characterize a new class of voting procedures, called Type-weighted Approval Voting. According to this family, each voter has a strictly positive and finite weight (the weight is necessarily the same for all voters with the same characteristics) and the alternative with the highest number of weighted votes is elected. The implemented voting procedure reduces to Approval Voting in case all voters are identical or the procedure assigns the same weight to all types. Using this idea, we also obtain a new characterization of Approval Voting.

Deanonymizing Users of the SafeWeb Anonymizing Service

The SafeWeb anonymizing system has been lauded by the press and loved by its users; self-described as "the most widely used online privacy service in the world," it served over 3,000,000 page views per day at its peak. SafeWeb was designed to defeat content blocking by firewalls and to defeat Web server attempts to identify users, all without degrading Web site behavior or requiring users to install specialized software. In this article we describe how these fundamentally incompatible requirements were realized in SafeWeb's architecture, resulting in spectacular failure modes under simple JavaScript attacks. These exploits allow adversaries to turn SafeWeb into a weapon against its users, inflicting more damage on them than would have been possible if they had never relied on SafeWeb technology. By bringing these problems to light, we hope to remind readers of the chasm that continues to separate popular and technical notions of security.

Déficits immunitaires primaires: diagnostic, prise en charge, quelques perspectives.

Severe primary immunodeficiencies (PID) are rare; their global incidence is comparable to that of childhood leukemia; they include more than 100 different entities. Clinical manifestations are: unusually severe or frequent infections or infections that do not respond to adequate treatment; an increased risk of certain malignancies; sometimes auto-immune manifestations. Delayed diagnosis and management of PID can lead to severe and irreversible complications or to death. PID can become manifest only in the adult; in common variable immune deficiency, the median age at diagnosis is between the 2nd and the 3rd decade of life. PID are often transmitted genetically; recent progresses in molecular biology have allowed more precise and earlier, including antenatal, diagnosis. Molecular treatment of 3 infants with a severe immunodeficiency has recently been achieved in April 2000. Those progresses were mostly based on the study of immunodeficiency databases. We present here the work of a Belgian group specialized in PID; meetings have started in June 1997. This group establishes guidelines for the diagnosis and treatment of PID, adapted to the local situation. The elaboration of a national register of PID is also underway; this has to provide all guaranties of anonymity to patients and families. Such a register already exists at the European level; it has provided the basis for new diagnostic and therapeutic possibilities. The inclusion of Belgian data in this register should allow essential progresses essential for our patients.

The outflow ranking method for weighted directed graphs

A ranking method assigns to every weighted directed graph a (weak) ordering of the nodes. In this paper we axiomatize the ranking method that ranks the nodes according to their outflow using four independent axioms. Besides the well-known axioms of anonymity and positive responsiveness we introduce outflow monotonicity – meaning that in pairwise comparison between two nodes, a node is not doing worse in case its own outflow does not decrease and the other node’s outflow does not increase – and order preservation – meaning that adding two weighted digraphs such that the pairwise ranking between two nodes is the same in both weighted digraphs, then this is also their pairwise ranking in the ‘sum’ weighted digraph. The outflow ranking method generalizes the ranking by outdegree for directed graphs, and therefore also generalizes the ranking by Copeland score for tournaments.

Impact of operator experience on information feedback and reusability

Keeping a record of operator experience remains a challenge to operation management and a major source of inefficiency in information management. The objective is to develop a framework that enables an explicit presentation of experience based on information use. A purposive sampling method is used to select four small and medium-sized enterprises as case studies. The unit of analysis is the production process in the machine shop. Data collection is by structured interview, observation and documentation. A comparative case analysis is applied. The findings suggest experience is an accumulation of tacit information feedback, which can be made explicit in information use interoperatability matrix. The matrix is conditioned upon information use typology, which is strategic in waste reduction. The limitations include difficulty of participant anonymity where the organisation nominates a participant. Areas for further research include application of the concepts to knowledge management and shop floor resource management.

Using evidence in policy: The importance of mediating beliefs and practices

This article argues that to understand the use of evidence in policy, we need to examine how meanings and practices in the civil service shape what is accepted as knowledge, and how differences between the beliefs and values of the academy and the polity can impede the flow and transfer of knowledge. It considers the importance of social context and shared meanings in legitimating knowledge. Who counts as legitimate knowledge providers has expanded and here the role of stakeholder groups and experiential knowledge is of particular interest. How hierarchy, anonymity, and generalist knowledge within the civil service mediate the use of evidence in policy is examined. The difference in values and ideology of the civil service and the academy has implications for how academic research is interpreted and used to formulate policy and for its position in knowledge power struggles. There are particular issues about the social science nature of evidence to inform rural policy being mediated in a government department more used to dealing with natural science knowledge.

Young People and Mental Health, Policy and Research Review

This brief focuses on issues relating to young people’s mental health. It draws on published research evidence and discussion at a Roundtable event organised by YouthAction Northern Ireland (YANI) and ARK and held in December 2012. Roundtable participants included officials from a number of government departments, Health Trusts, representatives from a range of NGOs, academics, and young people from YouthAction Northern Ireland’s Right Here Fermanagh
project and Young Men Talking Project who opened the debate with a contribution on what they think is important for young people’s mental health. The event was conducted under the anonymity of reporting allowed under the Chatham House Rule to encourage open debate.

Seeking help from everyone and no-one: Conceptualising the online help-seeking process among adolescent males

Online help-seeking is an emerging trend within the 21st century. Yet despite some movement towards developing online services, little is known about how young people locate, access and receive support online. This study aims to conceptualise the process of online help-seeking among adolescent males. Modified photo-elicitation techniques were employed within eight semi-structured focus group sessions with adolescent males aged 14 – 15 years (n= 56) across seven schools in Northern Ireland. Thematic analyses was conducted within an ontological framework of critical realism and an epistemological framework of contextualism. Informal online help-seeking pathways increased opportunity for social support and reduced stigma but also included loss of control and reduced anonymity. Formal pathways offered increased anonymity but concerns were raised regarding participants’ ability to locate and appraise the quality of information online. A conceptual model of online help-seeking has been developed to highlight the key help seeking pathways taken by adolescent males.
