Computer-implemented inventions feature in almost every field of technology, and although improvements to computer-based devices are routinely made in software, the circumstances in which patent protection is available remains unclear. The patentability of software varies considerably from jurisdiction to jurisdiction. Worryingly, there are variations in form, if not in substance, between patent offices working from the same legal source. Against the background of a sea change in the US position, there is the prospect of a clarification of the European Patent Office approach that will provide a platform for consistency in Europe. This paper focuses on the UK position, highlights the tension between the UK and the EPO and considers the key questions before the EPO's Enlarged Board of Appeal.  相似文献

Research Summary Unsupervised after‐school time for adolescents is a concern for parents and policymakers alike. Evidence linking unsupervised adolescent socializing to problem behavior outcomes heightens this concern among criminologists. Routine activities theory suggests that, when youth peer groups congregate away from adult authority, both opportunity for and motivation to engage in deviant acts increase. After‐school programs are a possible solution to unsupervised teen socializing during afternoon hours and are much in demand. However, empirical research has yet to test the relationship between the availability of after‐school programs and youth routine activities. This study presents evidence from a multisite, randomized, controlled trial of an after‐school program for middle‐school students in an urban school district. Policy Implications Youth in the treatment group engaged in less unsupervised socializing after school than youth in the control group but not as much less as would be expected if the after‐school program was providing consistent supervision to youth who would otherwise be unsupervised. Additional analyses examined why the influence of the after‐school program was not more pronounced. We found that, although program attendance was related to decreases in unsupervised socializing, the program did not attract many delinquency‐prone youths who were unsupervised, which suggests that the students most in need of the program did not benefit. Furthermore, data obtained from a mid‐year activity survey revealed that youth in the study were highly engaged in a variety of after‐school activities. The addition of the after‐school program into the mixture of available activities had little effect on the frequency with which students participated in organized activities after school.  相似文献

This paper discusses the impact of a leniency program on incentives within cartels. The objective of this program is to encourage a cartel member to confess and implicate his co-conspirators with hard evidence about their collusive agreement. We develop a simple model of cartel behavior under a first-price sealed-bid procurement auction and we show how an effective leniency program can prevent the internal coordination of cartel members.  相似文献

Diplomatic practitioners and policy makers represent an important, although frequently neglected, resource for teaching about international relations. The insights and stories provided by practitioners regarding key processes and events are often able to inspire our students to engage complex material and to play a much more active role in their own learning. While it is possible to argue that any type of practitioner contact is beneficial in terms of going beyond the material covered in textbooks, there are definite challenges associated with how to most effectively integrate these experiences with overall student learning. What type of format is most conducive to providing students with an insider's view? What type of preparation is required before contact with practitioners? How can student learning be evaluated in terms of assignments and debriefing activities? And finally, are traditional student feedback mechanisms appropriate for a course that involves a substantial practitioner component? This article investigates each of these challenges in the course of discussing one mechanism for bringing practitioner experience into the classroom, the United Nations Intensive Summer Study Program.  相似文献

拍摄影视作品破坏自然保护区生态环境是由自然保护区保护管理资金紧张、对自然保护区的利用缺乏相应的监督造成的。我国现有的法律体系没有对影视生态破坏问题做出合理的规制。建立以环境影响评价为前提的自然保护区社会性收费制度,辅以私人主体作为第三方力量的监督是解决这个问题的根本途径。  相似文献

Abstract

Why do public policies succeed or fail? The aim of this article is to contribute to answering this enduring research question in policy research through a comparative study of the variable efforts by Nordic governments to relocate their central agencies from the capital regions over a period of several decades. This was a radical redistributive policy program premised on a policy instrument – coercion – which was very alien to political systems characterized as consensual democracies. Hence, it is no surprise that only two out of seven relocation programs of any substance were successful. The really intriguing research question here is how any relocation program was achievable at all in a policy context where this was very unlikely. A broadly based multi-theoretical analytical framework linking interest groups, institutions, human agency in the form of policy entrepreneurship/design and situational factors is employed to solve this research puzzle. Findings from this study offer important contributions to the following research fields: comparative public policy, radical policy change and most specifically the so-called third generation of public policy implementation research.  相似文献
