Divorce, although a statistical norm, is a developmental trauma to the children involved. This article looks at the two-camp emotional environment of a divorcing family and its effect on the formation of a child's identity. By examining developmental ages, chosen according to divorce research, the author attempts to show how the interspouse emotional cathexes negatively affect a child's sense of self in ways specific to the child's age at the divorce.  相似文献

This article examines the use of Eye Movement Desensitization and Reprocessing (EMDR) in helping a client address problems with persistent anxiety and a lack of self-esteem. During EMDR treatment, the client explored the dichotomous thinking that had plagued her since childhood, and correspondingly, the role of childhood physical and emotional abuse in her chronic feelings of inadequacy and anxiety. The client experienced significant improvement in her levels of anxiety and problems with self-esteem, both at the end of treatment and at 1-year follow up. Qualitative and quantitative data are utilized in this case study outlining the use of EMDR with a client diagnosed with dysthymic disorder.  相似文献

The concern driving current debate on agricultural extension is increasingly that of how to help farmers learn how to deal with the complex world around them responsibly and profitably, in such a way that the extension worker is ancillary. This article seeks to deconstruct and provide a more reasoned assessment of agricultural extension services through a reflection on development paradigms, adult education, individual empowerment, and institutional pluralism. By calling into question the underlying ethical dimensions of agricultural extension, it is possible to develop an alternative paradigm and thereby generate new insights into it. The article concludes that the raison d'être of agricultural extension today must be to create an ethical basis which ensures that extension practices are more inclusive and thus responsive to the needs of farmers and other rural populations, integrating individual expectations into the wider socio-economic, cultural, political, and geographical environment.  相似文献

The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations.  相似文献

Abstract: This paper is concerned with an analysis of legislation, public administration and government expenditure decisions on policing activities. These three dimensions of government can be used as mechanisms of social control. Whether they are or not is an empirical question that has to be determined in each case. It is shown that there are no strict relationships between the three dimensions of government activity: separate decision-making is undertaken for each of the three dimensions. It is indicated that there are eight possible combinations of the three dimensions, assuming that the three dimensions of government activity are bivariate and discrete. The empirical analysis relates to the state of Queensland and it is concluded that Queensland can be described as a case consisting of authoritarian legislation, public administration contrary to the rule of law, and low policing expenditures.  相似文献

This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and a half have gradually shifted in terms of ownership and management from university/research institute to the private sector and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful innovative companies will emerge in larger numbers than in the past.
