Scholars of legislative studies typically use ideal point estimatesfrom scaling procedures to test theories of legislative politics.We contend that theory and methods may be better integratedby directly incorporating maintained and to be tested hypothesesin the statistical model used to estimate legislator preferences.In this view of theory and estimation, formal modeling (1) providesauxiliary assumptions that serve as constraints in the estimationprocess, and (2) generates testable predictions. The estimationand hypothesis testing procedure uses roll call data to evaluatethe validity of theoretically derived to be tested hypothesesin a world where maintained hypotheses are presumed true. Wearticulate the approach using the language of statistical inference(both frequentist and Bayesian). The approach is demonstratedin analyses of the well-studied Powell amendment to the federalaid-to-education bill in the 84th House and the Compromise of1790 in the 1st House. 相似文献

This article casts a critical eye over some of the (often ignored) assumptions which underlie recent appeals to community in crime prevention and control. The article considers the philosophical origins, ambiguities and tensions within such appeals. In so doing, it draws explicitly upon the growth of community safety and to a lesser extent restorative justice in Britain and considers some of the implications to which this shift may give rise. In particular, it focuses upon the manner in which appeals to community converge and collide with changing social relations which may undermine their progressive potential. Specific attention is given to the implications of: increasing social and spatial dislocation; the commodification of security; and policy debates about a growing underclass. It is argued that there is much confusion as to how, and to what extent, communities can contribute to the construction of social order. Within the dynamics of community safety and crime control practices there are dangers that security differentials may become increasingly significant characteristics of wealth and status with implications for social exclusion. This questions the extent to which crime is an appropriate vehicle around which to (re)construct open and tolerant communities. 相似文献

The “Science of Science Policy”: reflections on the important questions and the challenges they present 总被引:1,自引:1,他引:0
Adam B. Jaffe 《The Journal of Technology Transfer》2008,33(2):131-139
Developing the “Science of Science Policy” will require data collection and analysis related to the processes of innovation
and technological change, and the effects of government policy on those processes. There has been much work on these topics
in the last three decades, but there remain difficult problems of finding proxies for subtle concepts, endogeneity, distinguishing
private and social returns, untangling cumulative effects, measuring the impact of government programs in a true “but for”
sense, and sorting out national and global effects. I offer observations on how to think about these issues.
This paper was presented as the Keynote Address at the NSF Workshop on Advancing Measures of Innovation: Knowledge Flows,
Business Metrics, and Measurement Strategies, Arlington, VA, June 2006. 相似文献

This article aims to map some of the major implications forasylum–related law in Europe of the Refugee QualificationDirective, which twenty-four EU Member States were requiredto implement by 10 October 2006. It seeks to build on importantstudies of the Directive completed by, among others, Hemme Battjes,in his book European Asylum Law and International Law, Nijhoff2006, and Jane McAdam, in her book Complementary Protectionin International Refugee Law, OUP 2007, albeit it takes a differentview of some key questions. Part 2 deals with the impact of the Directive on the applicationand interpretation of the 1951 Refugee Convention and its 1967Protocol. It is argued that, even read simply as a set of provisionsgiving interpretive guidelines on the application of the RefugeeConvention, it affects many things concerned with refugee eligibility,since these provisions cover key elements of the refugee definition. Part 3 deals with the impact of the Directive on the asylum-relatedhuman rights jurisdiction that currently prevails in Europein one form or another.1 It is argued that the effect of theDirective is and must be to render Article 3 ECHR protection– or its domestic equivalent – a largely residualcategory, save in exclusion cases. Part 4 addresses to what extent, if at all, the Directive containsmandatory provisions and how, post-implementation, these canbe integrated into the national law of Member States. It isargued that, considered in purely textual terms, the key definitionaland interpretive provisions of the Directive are mostly in mandatoryform. Further, that whilst, by virtue of being a minimum standardsdirective, the Directive allows Member States to introduce orretain more favourable standards (A3), the same article stipulatesthat such standards must be compatible with the Directive. Thatproviso is of some importance given that the Directivespreamble (at R7) identifies as one objective the avoidance ofsecondary movements. In relation to articles of the Directivewhich specify in mandatory terms how elements of the refugeedefinition are to be applied, Member States cannot be free tointroduce or retain differing standards. Parts 5 and 6 analyse suggested differences, first, betweenthe Directives refugee definition and the Refugee Convention(it is argued that the only potential difference of real significanceconcerns the Directives rendering of the Article 1F exclusionclauses of the Refugee Convention) and, secondly, between theDirectives subsidiary protection definition and Article3 ECHR. The extent of symmetry between the new subsidiary protectioncriteria and ECHR protection under Article 3 is explored, inparticular, arguing that, whilst there are three respects inwhich subsidiary protection criteria are narrower (relatingto personal scope; the existence of cessation and exclusionclauses; and limited application to health cases),there may be limited respects in which it may be broader inscope than Article 3 ECHR. Part 7 examines patterns of implementation in the light of earlyevidence to hand from, for example, the November 2007 UNHCRsurvey of five Member States. The UK is considered as a furtherexample, that of a member state where, despite it being seenas unnecessary to make any substantial changes, the implementingmeasures have required important changes in method of approachand in conceptual language. 相似文献

The importance of “spillovers” in the policy mission of the advanced technology program 总被引:3,自引:0,他引:3
Adam B. Jaffe 《The Journal of Technology Transfer》1998,23(2):11-19
Government policies like the Advanced Technology Program (“ATP”) are intended, at least in part, to remedy the “market failure”
inherent in the fact that a significant portion of the social benefits of new knowledge and technology are not captured by
a firm that invests in R&D. ATP’s project selection, and its evaluation of the impact of its program, can be made more effective
by explicitly incorporating the analysis of such “spillovers.” For project selection, this means identifying technological,
organizational and economic factors that tend to oint to a large “spillover gap,” or deviation between the social and private
rates of return to a proposed project. For program evaluation and assessment, it means adapting existing study methods that
measure social returns to innovation in ways that explicitly capture spillover effects.
This paper is based on a study that I performed for the ATP, Economic Analysis of Research Spillovers: Implications for the
Advanced Technology Program, NIST GCR 97-708. I have benefited from comments and useful discussions with Zvi Griliches, Jeanne
Powell, Rosalie Ruegg, and Richard Spivack. Some of the ideas in this paper grew out of previous joint research with James
Adams. The views expressed herein are my own, however, and should not be attributed to any of these individuals or to the
ATP. 相似文献

Power Dynamics in an Experimental Game 总被引:1,自引:1,他引:0
We introduce a new experimental method for studying power. Drawing from multiple theoretical perspectives, we conceptualize
power as relational and structural, as well as comprised of different forms through which basic human needs can be met. Thus,
the method we introduce examines how, when faced with a particular need, people use multiple forms of power concurrently and
within a “field of influence,” namely, the other players in a game. This enabled us to examine how one form of power is transformed
into another and how power is transferred from one player to another through interaction, as well as to measure power as behavior,
as the exercise of choice, as potential, and as outcomes. Two experiments using egalitarian start conditions and a survivable
ecology demonstrated that participants used power to gain more power, creating inequality. Being the target of force made
some players unable to “survive” in the local ecology. Theoretical and methodological issues in the study of power are discussed
and the application of our game method to the study of power in other fields is considered. 相似文献
