This article explores the influence that state finance has had on the Romanian party system by examining the entry and exit of parties throughout the period of 1990 – 2004 and focusing on the number of parties that gained representation in the parliament as well as the party incumbency rate. I find that state finance has had a limited influence on the party system as a whole but has been influential for specific parties. I argue that the influence of state finance partly depends on when the system was introduced. In developing party systems, the influence of state finance on individual parties is more differential.  相似文献

The economics of the Holocaust is a many‐facetted subject that is an integral part of the Holocaust's history. This paper describes some of the results of the new research since 1990 and discusses the economic rationalities employed by the perpetrators in despoiling the Jews. Economic considerations accompanied the timing and pace of the expropriation of Jewish assets and their “Aryanization.” The new research also shows that there was widespread collaboration in the expropriation of the Jews by private interests both inside Germany and in German‐controlled Europe and that networks of bureaucrats and private interests joined to achieve Nazi goals. The combination of expropriation and mass murder was one of the aspects of the Holocaust that made it unique.  相似文献

This article tests cross-nationally the minority group threat thesis that public sentiments toward repressive crime-control policies reflect conflicted racial and ethnic relations. Using multiple data sets representing France, Belgium, the Netherlands, East and West Germany, Italy, Luxembourg, Denmark, Great Britain, Greece, Spain, Finland, Sweden, Austria, Canada, Ireland, and Portugal, we examine whether racial and ethnic intolerance—animus, resentments, or negative sentiments toward minorities—predicts greater support for the death penalty. Our results reveal that the respondents were significantly more likely to express support for capital punishment if they were racially or ethnically intolerant while controlling for other covariates of public opinion. These findings indicate that the link between support for capital punishment and racial and ethnic animus may occur universally in countries with conflicted racial and ethnic relations.  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
