Antonio Martinez-Roig Francisco Domingo-Salvany Jose Llorens-Terol Jose M. Ibañez-Cacho 《Child abuse & neglect》1983,7(3):261-263
A retrospective investigation of 97 psychologically maltreated children showed a clear relationship between clinical symptoms and the intensity of the abuse. Parental neglect resulted in impairment of intellectual and locomotor development and emotional and behavioral disorders. Neurotic manifestations of regressive type appeared in nearly half the preadolescents who suffered severe psychological abuse. Children under 6 years of age presented functional symptoms, including regression in toilet training and sleep disorders secondary to inadequate mothering. 相似文献

Canadian society is characterised by a plurality of immigrants and Canadian migration policy and corresponding recognition approaches are strongly geared to economic criteria, qualifications and skills. This paper addresses the question how immigrants who have acquired their highest qualification outside Canada are able to use their foreign qualifications and skills in their current job. The analyses are conducted to verify the assumptions of human capital theory as well as the lack of transferability of human capital across country borders. To answer these questions a labour market success index is developed, which is used as a dependent variable in regression models. The results show that traditional operationalisations of human capital (years of education, years of work experience and skills) have a positive effect on individual labour market success. At the same time, being born abroad and having acquired one’s highest qualification abroad in comparison to Canada, especially in a Non-Western country, has negative effects on the overall labour market success of an individual. Detailed comparisons regarding different indicators of labour market success also prove these comparatively negative effects. The results demonstrate the limited explanatory power of human capital theory and the necessity to complement it with Bourdieu’s concepts of social and cultural capital. 相似文献

This study examined the effects of two types of Information communication technology and media (ICT/media) use on college access using ICT/media to obtain college information as a mediator paying focused attention to English language learners. The study analyzed the Educational Longitudinal Study (ELS) from the US Department of Education, employing a survival analysis with structural equation modeling components. The results demonstrated that the frequent use of a computer for independent learning had significantly positive direct, indirect, and total effects on college entry for both English language learners and native English-speaking students. However, the digital gameplay had significantly negative effects. The study discusses the implications of using ICT/media. 相似文献

The low status of the foundation subjects (e.g. Music and Physical Education (PE)) in English primary schools is well documented. Using PE as an illustrative example, a thematic analysis of 51 PE trainee students’ assignments, based on their perceptions of a two-week experience in a primary school, highlighted a number of areas of concern (e.g. limited/inadequate preparation; insufficient teacher knowledge/confidence; variable/limited subject leadership and non-qualified teachers delivering the curriculum). The possibility of teachers, coaches and other external specialists learning collaboratively with and from each other within a community of practice/learning is proposed as one way of strengthening the foundation subjects within the primary school curriculum. 相似文献
