ABSTRACT This paper makes two major contributions: firstly, following on recent research, it offers a more detailed critical analysis of the historical role and structure of Employers’ Associations (EAs), concentrating on a detailed analysis of the range of member services offered by a local Employers’ Association within the Engineering Employers Federation (the EEF) during the 1970s. This focus is in contrast to the literature which has concentrated on the EAs national or ‘central peak’ level. It secondly addresses the ‘countervailing power’ hypothesis, and in so doing it illustrates the key roles of the disputes procedure. The study, as a typical or representative case, uses a qualitative methodology of documentary research combined with triangulation interviews of former officials: evidence which has so far not been prominent in the literature. This paper is, therefore, a significant addition to our understanding of these institutions. 相似文献

ABSTRACTThis introductory article revisits cross-border shadow exchanges in a comparative perspective and reflects on their theoretical implications. It explores the diversities and complexities of shadow operations and critically examines the concept of informality that is commonly used to describe such non-state-sanctioned practices. It further underlines the key role played by checkpoint politics in border governance. Border checkpoints serve both as a state institution in regulating border crossings as well as a political site where material and power exchanges among state and non-state actors are negotiated. Such negotiation of selective passage through state-controlled gateways is often predicated upon the skilful manipulation of time and space by experienced traders and brokers. 相似文献

The new judicial federalism emphasizes state court relianceon state constitutional grounds for the enhanced protectionof individual rights. Commentary in the legal literature givesthe impression of much state court activism in this area. However,a quantitative analysis of 2,286 equal protection cases decidedby state supreme courts between 1975 and 1984 shows much lowerlevels of the exclusive use of state constitutions. The dataalso reveal significant regional variations in the nature ofequal protection cases filed, the types of alleged discrimination,the use of independent and adequate state grounds, and the frequencyof judicial invalidation of state action. These variations areexplored in terms of political culture, the institutional featuresof the state judiciary, and the content of state bills of rights. 相似文献

We describe a method for obtaining specific and reproducible deoxyribonuclease I (DNase I) typing from liquid semen. Isoelectric focusing of the enzymes on polyacrylamide gel (IEF-PAGE, pH 3.5-5) was accomplished using a 0.5-mm thick gel. The separated isozymes were visualized by a new activity staining method, dried agarose film-overlay (DAFO). Pretreatment of semen samples with neuraminidase markedly enhanced the isozyme-band resolution and sensitivity. The method was simple and reliable, with high resolution and sensitivity. The DNase I types in semen samples were correlated with the types found in corresponding blood and urine samples. DNase I typing could therefore provide an additional discriminant characteristic in the forensic examination of semen. 相似文献

Structural arrangements in the Congress work against the use of analysis, but newer developments, such as growth in staff professionalism and activity of the congressional support agencies, tend to promote it. Interviews with committee staff show that they are aware of much analysis, use it primarily for political advantage, but that they also take it seriously as warning of problems and as guidance on particular issues. Staff value information more when they know and trust its source and understand its political motivations. The use of analysis to reconceptualize problems is not much in evidence, perhaps because such “enlightenment” takes place elsewhere and filters into the Congress through informal channels. 相似文献

The authors discuss a variety of forensic matters using cases in which they have been involved as experts. Pertinent issues
are illustrated in cases in which the offender is charged with homicide. The need for a comprehensive evaluation, the importance
of corroboration of the offender's statements, and the value of preparing a thorough report are discussed. 相似文献
