Western policymakers have come to take Egypt's foreign policy orientation for granted in recent decades. After President Anwar Sadat's dramatic split from the Soviet bloc and embrace of peace with Israel in the 1970s, Egypt became a reliable but rarely exciting diplomatic partner. Little appreciated has been the centrality of foreign policy to Egypt's internal interests as well as its external ones, and the extent to which changes in either the domestic or international environment could trigger the Egyptians to reassess their stance. The present article examines the interests that Egyptian foreign policy serves, and it analyses factors that could prompt a future Egyptian government to adopt different policies in order to serve those interests more effectively.  相似文献

Research into community corrections officers’ perceptions of the needs of ex-offenders has largely been overlooked. While some empirical research has emerged regarding federal parole officers’ perceptions, it is conceptually incomplete. A gap in the literature remains regarding the concordance or discordance between offenders and community corrections officers’ perceptions of offender needs and the opportunities for success upon release. Using a sample of community corrections officers in Seattle, Washington, this research examined officer perception of ex-offender needs, the value officers’ placed on the specific needs, and the opportunities available for offenders to meet their needs. Differences between officers emerged including the finding that female officers rated needs and challenges for offenders significantly different than male officers. Policy implications of the research are discussed. This research was made possible due to a grant award from the College of Arts and Sciences at Seattle University. This research was first presented at the 2005 Academy of Criminal Justice Sciences Conference in Chicago. We are grateful to Mac Pevey and Keven Bovenkamp from the Washington State Department of Corrections and Bill Corn and Tim McTighe from United States Probation and Pretrial Services for their support, assistance, and for making the study possible. A special thanks to our research assistant Tania Reyes who was instrumental in collecting the data for this investigation.  相似文献

Abstract: The Quantifiler® Duo DNA Quantification kit enables simultaneous quantification of human DNA and human male DNA as well as detection of inhibitors of PCR in a single real-time PCR well. Pooled human male genomic DNA is used to generate standard curves for both human (ribonuclease P RNA component H1) and human male (sex determining region Y) specific targets. A shift in the cycle threshold (CT) values for the internal positive control monitors the presence of PCR inhibitors in a sample. The assay is human specific and exhibits a high dynamic range from 0.023 to 50 ng/μL. In addition, the multiplex assay can detect as little as 25 pg/μL of human male DNA in the presence of a 1000-fold excess of human female DNA. The multiplex assay provides assessment of the DNA extract and guidance for the selection of the appropriate AmpFℓSTR® Amplification Kit to obtain interpretable short tandem repeat profiles.  相似文献

The Remediation Cost Cap (RCC) market has experienced the boom-bust cycle common to many industries. This article discusses the current market conditions and insurance providers offering the product. The article asks you to determine whether you really need a RCC policy, and if so, provides helpful hints for managing the submission process. Finally, the article discusses the effects of contraction of RCC providers have had on the liability transfer industry.  相似文献

This article identifies the need for an appropriate methodology for evaluating Fair Trade, given that most evaluations to date have been in-house or commissioned reviews and hence have not followed a consistent approach. Focusing on the development aspects of Fair Trade, the article reviews a range of impact evaluation methods and presents a detailed methodology for analysing Fair Trade. This methodology incorporates standard project evaluation criteria and is based on a wide range of proven methods for collecting and analysing data, principally qualitative but also quantitative. This framework is a modular package from which practitioners may select according to their needs and means, while still retaining an overarching logic. The article illustrates its use by reference to evaluations undertaken in Costa Rica, Ghana, Nicaragua, and Tanzania. The approach allows for a comprehensive understanding of Fair Trade programmes and enables these to be compared with conventional development projects.  相似文献
