This paper contributes to ard a better understanding of innovation in the service sector by focusing on the disparate nature of R&D in the U.S. service sector as learned through case studies of the U.S. telecommunications, financial services, systems integration services, and research and development testing services industries. Based on this understanding of the nature and scope of R&D therein, a new policy-oriented model of innovation specific to the service sector is posited. Also, policy recommendations are offered with regard to the public sector’s collection and interpretation of R&D data related to the service sector.   相似文献

The periodic Summits of the Americas are the highest form of regional multilateralism in the Western Hemisphere, but summits lack their own means to implement their mandates. Hence, Summit Plans of Action assign many initiatives to existing regional institutions, especially the Organization of American States (OAS) and the Inter-American Development Bank (IDB). But a notable difference exists in the character and degree to which these two institutions have responded to their unfunded mandates, in that the OAS has become “nested” under the hierarchy of summitry, while the IDB has eschewed subordination in favor of a “parallel” relationship pursuing largely convergent activities. Relying on extensive interviews and reviews of open source and internal documents, six variables are found to explain this differential response: ministerial authorities, competing mandates, institutional missions, internal structures, membership and leadership. Yet for both regional institutions there remains a wide gap between the directives emanating from the Summits and what the two regional institutions have been—and could be—accomplishing. The study concludes with recommendations to improve institutional design. JEL codes L31 · F42 · F02 · D73 · F1  相似文献

The Child Abduction Convention, an international treaty, protects custody rights internationally among its member states by providing a remedy of return in cases where a child was wrongfully removed in violation of a parent's custody right. There is no such remedy for the violation of a parent's access (or visitation) rights. A ne exeat clause in a child custody agreement restrains a custodial parent from removing a child from a predetermined jurisdiction (such as a particular country) and can be issued when there is a risk that the custodial parent might flee to another country with the child(ren). Currently there is a circuit split within the United States as to whether a ne exeat right coupled with the right of access should equal a protected custody right under the Convention. Most international courts protect the ne exeat right under the Convention; however some do not. A ne exeat right should convey a protected custody right for policy reasons. The beneficial implications of a ne exeat right creating a protected custody right under the Child Abduction Convention clearly outweigh the detriments. While there is no instant solution to the inconsistencies among various courts in interpreting the Child Abduction Conventions’ scope in regard to a ne exeat right, there are ways to resolve the problem. If consistency in judicial interpretation cannot be achieved, a movement needs to be initiated to create a protocol to the Child Abduction Convention to further explain the scope of custody rights and ne exeat rights under the Convention.  相似文献

The purpose of this paper is to explore the “critical thinking” approach to teaching and develop those concepts into meaningful instructional activities in the classroom. The authors offer practical suggestions based on the critical thinking philosophy for implementing an active learning approach. The case study method serves as the foundation for an investigative process course and lead-up activity to the simulated preliminary and follow-up investigation. The instructor presents the critical thinking process and content information that enables students to perform five basic progressions: (1) case studies; (2) the preliminary investigation; (3) follow-up; (4) suppression hearing; and (5) moot court criminal justice simulations.  相似文献

This study explored factors associated with a lifetime history of domestic violence and sexual assault in a sample of welfare recipients in Illinois. Results indicate that childhood exposure to domestic violence is a risk factor for both sexual assault and domestic violence victimization, but that childhood physical abuse is only a risk factor for domestic violence. Increased education and employment skills and having more children were also risk factors for domestic violence victimization. Domestic violence was significantly associated with depression, while sexual assault was associated with low social support and a greater perceived need for mental health services. Frequent alcohol and drug use were not associated with either type of victimization. Research implications are discussed.  相似文献

Although Asia is the most important region of the world when it comes to capital punishment, it is also one of the most understudied. This article identifies four research questions that deserve attention from students and scholars who believe taking capital punishment seriously requires studying Asia seriously too. What are the empirical contours of capital punishment in contemporary Asia? What are the histories of capital punishment in Asia? Can Western theories of capital punishment explain patterns and changes in Asia? And what is the future of capital punishment in Asia? If researchers take the trouble to explore these questions, the death penalty will not only become an interesting window into law and society in Asia, but Asia will prove to be an instructive window into the death penalty—the gravest real-life problem in the law.  相似文献
