OBJECTIVES: To determine the self-reported prevalence of child and partner physical and emotional abuse in the north of Portugal and to investigate attitudes about these forms of family violence. METHODS: Data were collected by questionnaire from a representative sample of parents in two-parent families with children under the age of 18 years. A total of 2,391 parents participated (1,057 males), aged 20-67 years. Four questionnaires were used, one behavioral and one attitudinal, for each of the forms of abuse: child and partner. RESULTS: At least one act of emotional or physical abuse towards a child during the previous year was reported by 25.9% of participants (12.3% reported physically abusive and 22.4% emotionally abusive acts). Abuse of a partner was reported by 26.2% of participants; at least one act of physical abuse during the previous year was reported by 12% and of emotional abuse by 23.7%. The attitudinal data, however, showed general disapproval of the use of violence, both for disciplining children and within marital relationships. The degree of self-reported support for physical punishment was higher in participants who reported using abusive behavior. Females more commonly reported acts of child abuse, and males reported acts of partner abuse. Both forms of self-reported abuse showed an association with low educational and socio-economic status. CONCLUSIONS: This is the first study in Portugal to analyze family violence through self-report using a representative sample. The findings indicate that child and partner abuse constitute a significant problem in the region of northern Portugal. The discrepancy between the self-reported behavioral and attitudinal data may reflect conflicts in Portuguese society, which is undergoing substantial cultural changes.  相似文献

The paper reports a case study where a relatively lightweight technology in the form of a Web-based questionnaire was used to support members of a real community of professionals in externalizing and sharing their good practices and achieving a better awareness of and agreement on topics of common interest. We focused on an important medical association that counts more 1000 doctors all around the world as its members. In particular, we report how this association used the occasion of the on-line survey enabled by our technology to increase the awareness of its members about the actual heterogeneity of preferences existing in their daily clinical practice, and to trigger discussion toward a better consensus on best practices, appropriate indications, and treatments of choice for their profession and practice. We also report the result of a post-hoc evaluation of the Web-based technology employed, and draw some implications for the better design of this kind of tool in order to collect and share collective knowledge in specific professional domains.  相似文献

We need a common name to have a clear identity which best describes the scope of the work we carry out for the patients.A clear and easily understood name which reflects the level of education and training of a specialist in the medical laboratory, and hence eligibility to be on the EC4 Register, is therefore needed, whatever academic background and whether polyvalent or sub-specialised.  相似文献

The use of numerical simulation methods for the Cultural Heritage is of increasing importance for the analysis, conservation, restoration and appreciation of works of art. This is particularly important when their preservation and planned maintenance is the primary aim. Today museums, and particularly historical buildings converted to museums, should be considered as places where precious artefacts should have first-rate protection and conservation. It is a question of solving the compromise between protection, conservation and comfort for works of art and/or visitors, with the consequence that preservation and planned maintenance criteria must prevail over use requirements. Refurbishment and conservation of a building, and requirements for visitor presence and works of art need different thermo-physical indoor parameter values. The present paper concerns the thermal and air velocity analysis of the Salone dei Duecento (the Hall of the Two Hundred of the Palazzo Vecchio (Old Palace)) in Florence. In this paper an appropriate transient 3D model by Computational Fluid Dynamics (CFD) software based on the finite element method (FEM) was used. Variations and interaction between indoor and outdoor microclimatic conditions, and thermo-physical behaviour of the building connected to lighting, visitor presence and cooling–heating fan coils system were considered. The 3D modelling method provided by the present paper can be applied to several situations where there is interaction between outdoor and indoor climate variations and the building structure. It can be very useful for defining measures to preserve tapestries, understanding deterioration processes, and developing new conservation techniques and strategies for care and exhibition.  相似文献
