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

Wikipedia, the free online encyclopedia that can be edited by users, is growing both in the number of content articles written as well as the number of registered users. Students rely on Wikipedia (Purcell et al., 2012) and Wikipedia, through tools, is enabling users to make better decisions regarding the information they find (Gray, 2013; Kyrios, 2013; Lamb & Johnson, 2013). However, are teachers and librarians in secondary schools learning to embrace the online encyclopedia? This exploratory study surveyed classroom teachers and librarians/library staff regarding their perceptions of the effects of Wikipedia use by students in research assignments, their perceptions of the need for school policy regarding the use of Wikipedia by students, and regarding their knowledge of the Page Assessment Guide designed to help users judge the reliability of the information on a page.  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

Leg stiffness is a modifiable mechanical property that may be related to soft tissue injury risk. The purpose of this study was to examine mean leg stiffness and bilateral differences in leg stiffness across an entire professional Australian Football League (AFL) season, and determine whether this parameter was related to the incidence of lower body soft tissue injury. The stiffness of the left and right legs of 39 professional AFL players (age 24.4 ± 4.4 years, body mass 87.4 ± 8.1 kg, stature 1.87 ± 0.07 m) was measured using a unilateral hopping test at least once per month throughout the season. Injury data were obtained directly from the head medical officer at the football club. Mean leg stiffness and bilateral differences in leg stiffness were compared between the injured and non-injured players. There was no difference between the season mean leg stiffness values for the injured (219.3 ± 16.1 N x m(-1) x kg(-1)) and non-injured (217.4 ± 14.9 N x m(-1) x kg(-1); P = 0.721) groups. The injured group (7.5 ± 3.0%) recorded a significantly higher season mean bilateral difference in leg stiffness than the non-injured group (5.5 ± 1.3%; P = 0.05). A relatively high bilateral difference in leg stiffness appears to be related to the incidence of soft tissue injury in Australian football players. This information is of particular importance to medical and conditioning staff across a variety of sports.  相似文献

In this paper we relate participation in full-time Higher Education in Scotland to the geographic and social characteristics of the areas where people reside. National data on students at Higher Education institutions in all parts of the UK are used to calculate the rates, with areas of residence defined by their addresses at the times of applying to the institutions. Population data and the social characteristics of the areas were derived from the 1991 Census. The smallest geographic area considered was the Post-Code Sector, consisting of around 5000 households. Economic factors, social class, unemployment and housing tenure were strongly related to participation in the expected direction. However, different strengths of effect were found in different parts of the country. The analyses also suggest that cultural factors may be important, especially away from the major cities, and that aspects of accessibility to the institutions may also be of relevance in some areas.  相似文献

Using a phenomenological approach, the study sets out to discover whether it can derive a concept of good teaching from a group of university lecturers and the extent to which it compares and contrasts with a corresponding student concept of good teaching. The subjects were all mature adults, usually postgraduate, and often practising professionals with a wide experience of the university system. A single concept of what the students thought of as good teaching, and two categories ('pre-existing' and 'reflective') of what the teachers thought of as good teaching were developed. The extent to which these concepts overlap-and fail to overlap even after reflection-is used to discuss the importance of developing appropriate metacognitive strategies in human adult learning so that each group (teachers and learners) becomes more aware of what the other is attempting to do. The importance of out-of-class behaviours is seen as particularly valuable in this respect.  相似文献

Maple Syrup Urine Disease is an autosomal recessive disorder caused by a deficiency in the activity of the branched-chain α-ketoacid dehydrogenase complex. This rare disorder represents one of the causes of acute neonatal illness which results in devastating disturbances of neurological development. On investigation of 1750 infants with neurological impairment for inborn errors of amino acid metabolism, 4 neonates with classical maple syrup urine disease were detected. These otherwise normal neonates presented in the first week after birth with seizures, lethargy and refusal of feeds, hypoglycemia and metabolic acidosis. The plasma and urine concentrations of the branched-chain amino acids were increased and there was ketoaciduria. Two of these neonates expired before specific treatment could be instituted. Routine biochemical screening of neonates with acute illness could unearth many cases of this rare inherited metabolic disease.  相似文献
