Theories of policy instrument choice have gone through several “generations” as theorists have moved from the analysis of individual instruments to comparative studies of instrument selection and the development of theories of instrument choice within implementation “mixes” or “governance strategies.” Current “next generation” theory on policy instruments centers on the question of the optimality of instrument choices. However, empirically assessing the nature of instrument mixes is quite a complex affair, involving considerable methodological difficulties and conceptual ambiguities related to the definition and measurement of policy sector and instruments and their interrelationships. Using materials generated by Canadian governments, this article examines the practical utility and drawbacks of three techniques used in the literature to inventory instruments and identify instrument ecologies and mixes: the conventional “policy domain” approach suggested by Burstein (1991 ); the “program” approach developed by Rose (1988a ); and the “legislative” approach used by Hosseus and Pal (1997 ). This article suggests that all three approaches must be used in order to develop even a modest inventory of policy instruments, but that additional problems exist with availability and accessibility of data, both in general and in terms of reconciling materials developed using these different approaches, which makes the analysis of instrument mixes a time‐consuming and expensive affair.  相似文献

We have shown that there is a difference between individuals in their tendency to deposit DNA on an item when it is touched. While a good DNA shedder may leave behind a full DNA profile immediately after hand washing, poor DNA shedders may only do so when their hands have not been washed for a period of 6h. We have also demonstrated that transfer of DNA from one individual (A) to another (B) and subsequently to an object is possible under specific laboratory conditions using the AMPFISTR SGM Plus multiplex at both 28 and 34 PCR cycles. This is a form of secondary transfer. If a 30 min or 1h delay was introduced before contact of individual B with the object then at 34 cycles a mixture of profiles from both individuals was recovered. We have also determined that the quantity and quality of DNA profiles recovered is dependent upon the particular individuals involved in the transfer process. The findings reported here are preliminary and further investigations are underway in order to further add to understanding of the issues of DNA transfer and persistence.  相似文献

ABSTRACT

Special districts now constitute about 42% of all U.S. jurisdictions, yet little is known about them. Some critics are concerned that special districts and their staffs have insufficient community commitment. This study, based on a national survey of senior managers in large special districts, examines activities and programs of special district managers that foster community building and engagement, including correlates of these. Study results reveal that special districts are committed to their communities and several strategies and conditions are associated with increased community commitment, such as jobs that focus on community interactions, service type, and ethics management, as well as, to a lesser extent, graduate degree qualifications and charters that specify the role of managers in promoting the public interest and in relation to the board.  相似文献

This paper examines the phenomenon of marginalization through the lens of the relatively neglected concept of contribution. It argues that the opportunity to contribute positively to others’ lives is an important component of human well-being which promotes the goods of meaning, self-respect and reliance. Where individuals enjoy that opportunity, they are on that account less marginalized. Contributory practices channelled through publicly recognized median institutions (between the state and the personal sphere) are especially valuable.  相似文献

U.S. energy firms are increasingly expanding their production of natural gas oftentimes by relying on a controversial extraction technique known as hydraulic fracturing. While proponents cite a litany of benefits including economic development and reduced carbon emissions, opponents articulate concerns typically centering on environmental quality. Caught between these opposing points of view, states are turning to disclosure requirements. Yet all disclosure statutes are not created equally. In order to better understand this variation, I utilize Abel, Stephan, and Kraft's (ASK) 2007 performance model, which evaluates the effectiveness of information‐based disclosure rules for industry. The model here, however, is applied in an attempt to understand why disclosure regulations emerge and vary across states. Results generally validate the ASK approach but with one caveat. I find that in the context of differing disclosure regulations, the ASK model's pollution severity/risk measure may be refined by including risk perception.  相似文献

Short reviews     
Abstract

In an attempt to publish some reviews sooner after material comes out, the Bulletin of Concerned Asian Scholars has added this section of short reviews of individual books, movies, TV series, and so on. For more information about short reviews as well as review essays, see the introduction to the list of books to review on p. 92 of this issue.  相似文献
