This article argues that counterterrorism effectiveness is a distinct, discursive construction that politicians use to offer a rationalization of measures adopted under conditions of inherent uncertainty. Even in the face of multiple limits of knowability, decision makers need to offer “rational” justifications complying with persisting expectations of “evidence-based” policy and sound deliberation in modern societies. This article develops a new perspective on the political role of counterterrorism effectiveness highlighting the symbolic importance of knowledge claims and prevailing standards of modern rationality. It illustrates its arguments through a case study on the justification of biometric passports as an effective counterterrorist tool. 相似文献

This article is concerned with assessing the effectiveness of markets for complex professional services in social care. The issue is explored through an account of developments in the children's residential care sector. Over the past five years there has been a steady expansion in the role of external markets in this area. However, this was not required by the Children Act 1989 and has become the subject of considerable debate between policy makers and practitioners. While some favour an extension of choice, others argue that a further decline in local authority run provision will be both costly and detrimental in terms of meeting key policy goals. In order to assess these claims, reference is made to the findings of a study of purchasing practices for children's residential care in twelve local authorities in England and Wales. The impact of the emerging market is analysed along two dimensions. Firstly, we assess how far it is operating efficiently, concentrating on market structure, information and transaction costs. Secondly, attention is given to the impact of market changes on the policy objectives of: localized placements; ensuring adequate safeguards; and matching needs and services. The results reveal that there have been significant costs associated with markets in children's services. In a context of government efforts to promote modes of service delivery on the basis of 'what works', these difficulties have certain implications. Not only do they draw attention to the need for greater collaboration between purchasers and providers, they also point to the continued relevance and usefulness of local authority managed provision. 相似文献

In Ankole District, Western Uganda, a serious land problem is developing. Land is increasingly being acquired for commercial and speculative purposes; access to land for the majority of Banyankore becomes problematic. This paper is concerned with the origins of only two avenues of land acquisition in Ankole, mailo grants and individual freehold titles. Both have contributed to nascent problems, if only through their inducement of interests in land as a commodity. The paper explores the effects of these policies on Ankole sociopolitical divisions and questions general (especially ‘individualization') land policies concerned with agricultural growth alone. 相似文献

Abstract In the light of official apparent assumptions about the use and effectiveness of C & IT in teaching and learning this article, by reference to empirical studies carried out by the authors and others, offers observations and conclusions about the most effective use of CAL in delivering legal education. We detail the type of electronic packages used in delivering modules to Woherhampton students (studying both undergraduate and postgraduate programmes), evaluate their responses and conclude by making recommendations as to the most effective use of CAL in academic programmes; in particular that by itself it be limited to providing a foundation of basic legal knowledge upon which the higher cognitive skills can be developed by face to face contact 相似文献

This article is both a biographical sketch of the career of Nehemia Levtzion and a reminiscence. Levtzion grew up in Israel during the period of its founding. He early chose to study Islamization in Africa and became the leading interpreter of the history of Islam in West Africa. Though often called on to assume administrative responsibilities in the Israeli educational system, he maintained a commitment to scholarship. The small conferences he held in Jerusalem over the years often involved a re-thinking of basic problems in the history of Islam in Africa and in the larger Muslim world. He was particularly interested in processes of conversion and the dynamics of change. Though he described many varieties of Islam and different levels of Islamization, he never accepted the notion of a distinctively Africa Islam. He saw instead processes that were similar throughout the Muslim world. 相似文献
