The second part of this paper deals with the legal basis of medico-statistical data, and shows the type of report made by Medical Officers of Health and by private practitioners to the Norwegian Central Statistical Office. These reports deal with infectious diseases, with certain types of mental disease, and certain special diseases like tuberculosis. The system of classifying causes of death is also explained. Other sections deal with hospital and morbidity statistics and statistics obtained from recruiting authorities.  相似文献

A number of studies have suggested breastfed infants have improved bonding and attachment or cognitive development outcomes. However, mechanisms by which these differences might develop are poorly understood. We used maternal time use data to examine whether exclusively breastfeeding mothers spend more time in close interactive behaviors with their infants than mothers who have commenced or completed weaning. Mothers (188) participating in a time use survey recorded infant feeding activities for 24 h over a 7 day period using an electronic device. Tracking was conducted at 3, 6, and 9 months postpartum. Data was collected for maternal activities including infant feeding and time spent in emotional care. The mothers of exclusively breastfed infants aged 3–6 months fed them frequently and total time spent in breastfeeding averaged around 17 h a week. Maternal time spent in emotional care was also substantial, and found to correlate positively with time spent breastfeeding. Exclusively breastfed infants received greatest amounts of emotional care from their mother, and exclusively formula fed infants the least. Mixed fed infants received more emotional care time than formula fed infants, but less than fully breastfed infants. These findings may help explain the differential cognitive developmental outcomes reported in the medical literature for breastfed and non breastfed infants.  相似文献

This essay identifies ten significant methodological challenges for understanding aggression and gender. In light of the recent explosion of research on indirect/relational/social aggression, it seems important to clarify gaps in our current understanding and to identify promising methods by which better answers might be found. The discussion begins with basic issues of definitions, contexts and subtypes, moves on to points concerning sampling and measures, and addresses whether current evidence warrants deciding that girls are as aggressive as boys. We conclude that although research has shown that the majority of girls' aggression takes indirect/relational/social forms, it is premature to conclude that boys do not also engage in these behaviors. We caution against assuming that physical and indirect/relational/social aggression are comparable in their developmental origins and consequences, and urge researchers to consider that fully understanding indirect/relational/social aggression might require different conceptual frameworks and research methods.  相似文献

In the interest of developing a more holistic and integrated understanding of young children's experience of stories, this study describes preschoolers' emotional attachments to stories and the cultural beliefs and practices which surround such attachments. Thirty-two European-American, middle-class families, participated in an interview study of their children's story attachments, and five of these mothers also participated in a short-term, longitudinal diary study. Every child experienced at least two emotional attachments to stories. Children were captivated by stories presented in different media, with many attachments occurring around video stories in addition to books. They expressed their attachments by repeatedly requesting the story, expressing strong feelings, and enacting the story in pretend play. Story attachments were social in two fundamental ways: children created relationships with the characters in their favorite stories, and story attachments emerged in the context of relationships with caregivers whose beliefs and practices supported such attachments.  相似文献

In recent years there has been a renewed interest in psychodynamic ideas within the family therapy literature. While some authors have explored the usefulness of psychodynamic concepts in the systemic context (Byng-Hall, 1995; Flaskas, 1993, 1996; Luepnitz, 1988, 1997), others have argued that psychodynamic models of family therapy should be given more credence in systemic work with families (Guttman, 1991). This paper describes Object Relations Family Therapy (ORFT), a psychoanalytic model of family therapy, in plain English in order to minimise the obscurity of some of the existing terminology and to emphasise the utility of more contemporary formulations. ORFT addresses the interface between psychoanalytic and systemic theories. It offers a way of conceptualising complex family dynamics at both the interpersonal and intrapsychic levels. It also integrates an understanding of nonverbal, unstated and often implicit processes in its formulation of problem development. The unique contribution of ORFT is elaborated using a clinical example.  相似文献

Little explored in terms of work, the world of pollsters is a good example of the transformations affecting the contemporary world of labor. At the intersection of sociology of work, itineraries and gender, this ethnographic survey of one of the companies of the sector and its executives gets beyond the expressions of discomfort or withdrawal classically observed in that category, by focusing on those who rebel against their company and their work. The study reveals the process by which certain employees, women in particular, knowingly leave all the benefits included in their employment and status. Their silent disaffiliation is however temporary because the people I met are forced to work, yet they have the possibility of branching off towards a job rewarding in terms of identity albeit less prestigious and safe. These bifurcations also reveal inequalities among managers and, especially in the case of women, a weakening of their itineraries in the longer run.  相似文献
