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

Corporate governance theory suggests that companies with dispersed and indirect ownership suffer from agency costs. A worst case is where several political authorities jointly own a company, which allows managers to operate with inferior efficiency. In political economy, the manager is not the major agency problem. Elected politicians may impair efficiency to improve their re‐election prospects. Since politicians have less influence in jointly owned firms, such companies are expected to perform better than those owned by a single public authority. Consistent with corporate governance – but not political economy – the empirical analysis suggests that dispersed municipal ownership impairs cost efficiency. In the Norwegian case of municipal refuse collection presented here, costs of dispersed ownership often outstrip gains from economies of scale. Use of jointly owned companies is not necessarily a proper response to efficiency problems inherent a fragmented local government structure.  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

Conclusion In 1984, after years of study and thorough debate, a bipartisan majority of the Congress enacted perhaps the most far-reaching reform of the federal criminal justice system in the history of the United States. The Sentencing Reform Act and the federal sentencing guidelines are now beginning to produce data indicating that the objectives of avoiding unwarranted disparity and invidious discrimination are being achieved.After an uncertain beginning, the guidelines are gaining acceptance by courts and criminal justice practitioners. As one appellate court observed in admonishing lower courts that the guidelines must be respected:We have embarked on a new course. Only time will tell whether the use of the guidelines will result in an improvement over the old system. But unless we follow the spirit and written directions of the guidelines, we will never know if they have been given a fair test. They at least deserve that.Indeed, the bold new approach to sentencing that is being followed today in federal courthouses throughout the United States deserves an opportunity to succeed, given its many beneficial features and the lofty goals toward which the reforms are directed. While ample work remains for the United States Sentencing Commission to monitor and improve the guidelines, indications at this still early date are that the experiment is succeeding.An earlier version of this paper was presented at the fifth conference of the Society for the Reform of Criminal Law, Parliament House, Edinburgh, Scotland, August 5–9, 1990.

New York State experimented with replacing their litigation-oriented system for achieving toxic dump site cleanup with one promising to lower transaction costs through alternative dispute resolution. Our analysis of outcomes is informed by three generations of implementation work focusing on (1) the motivations and incentives shaping individual behavior, (2) the larger organizational and political factors associated with variation across cases, and (3) the generic properties of policy implements. This mosaic approach to explanation produces, we believe, a more lifelike picture of use to policy makers for understanding the dynamic and interrelated nature of their choices.  相似文献
