This article reviews the experience of SEMATECH as a model for high-technology research consortia. SEMATECH's original aims of developing next-generation manufacturing technology proved hard to achieve, and the program has refocused on generic technology and the equipment industry infrastructure. Though more modest, these new objectives have produced significant tangible results. The study considers the reasons for the change and implications for consortium design. This is contrasted with the history of other major collaborative research programs in Japan, Europe, and the United States.  相似文献

This paper uses an augmented Solow model, with cross section data, to measure the effect on per-capita income of a) the entrenchment of various rights in a country's constitution and b) the level of economic freedom in a country, broadly construed. The results suggest that entrenchment,per se, of any single right seldom has a significant general economic effect, while the effect of economic freedom is significant and substantial. The paper then considers whether such evidence could support the proposition that “constitutions do not matter.” While it concludes otherwise, it does caution against incurring excessive negotiation costs to obtain entrenchment of a comprehensive “wish list” of rights.  相似文献

This paper estimates the potential social cost of trade barriers using the Harberger and the Tullock/Posner approaches for a sample of U.S. food and tobacco manufacturing industries. In addition, it tests the relationship between the computed welfare losses and special-interest political activity (PAC contributions). If all rents were dissipated through rent seeking, the social cost of trade barriers would be about 12.5 percent of domestic consumption and would be particularly large for sugar and milk products where quotas are the main instrument of protection. Furthermore, the results indicate that welfare losses are positively associated with industry lobbying but the strength of such association is strongly dependent on industry concentration.  相似文献

Suppose the optimizing consumer only has local information, then what? Obviously, there will be a random element of consumption. The link between the frequency distribution of consumption by person and preference surface is worked out. Under convex preferences there will be a unimodal distribution and conversely. A local optimizing theory of addictive behavior is developed from nonconvex preferences. The resulting bimodal distribution of consumption implies a nonrobust outcome for median voter politics. Such a local optimizing model of addiction is compared with globally optimizing models of addiction.  相似文献

Abstract: Since the era of reform triggered by the Committee on Government Productivity during the early 1970s, there has been surprisingly little writing about public service reform in Ontario. This article surveys developments since the early 1980s, reviewing the changes that occurred during the Davis, Peterson, and Rae governments pertaining to the structure and integrity of the public service, human resource development, relocation, accountability regimes, reorganization and restraint initiatives, to name only a few. We review the rise and fall of the Tomorrow Project, and how the Rae government developed an interest in public management issues as part of its policy and restraint agendas. As a frame for our analysis, we invoke the metaphor of “streams, springs, and stones” to convey not only the breadth and complexity of public service reform but also its enduring themes and issues. Sonirnnire: Depuis l'époque des réformes déclenchées par le Comité sur la productivité gouvernementale vers le début des années 1970, curieusement peu d'auteurs se sont penchés sur la réforme de la Fonction publique en Ontario. Cet article s'intéresse à l'évolution qui s'est produite depuis le début des années 1980, examinant les changements survenus sous les gouvernements Davis, Peterson et Rae en ce qui concerne la structure et l'intégrité de la Fonction publique, le développement des ressources humaines, les déménagements, les régimes d'imputabilité, ainsi que les initiatives de reorganisation et d'austérité, pour ne citer que ceux-là. Nous analysons la montée et la chute du Projet “ Demain ” et comment le gouvernement Rae a commencéà s'intéresser aux questions de gestion publique dans le cadre de son programme oû figuraient l'austérité et la définition des politiques. Pour encadrer notre analyse, nous faisons appel à la métaphore des “ courants, sources et pierres ” pour indiquer non seulement l'ampleur et la complexité des réformes de la Fonction publique mais aussi sa probématique et ses thèmes permanents.  相似文献

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen. We gratefully acknowledge the contributions of study participants and staff.

This paper explores the organizational strategies used to represent information about political actors in memory, and it illustrates the usefulness of a specific measure, the adjusted ratio of clustering score (ARC), for inferring memory structure. Assuming the operation of an associative network model, we argue that information about a political actor can be organized along three distinct dimensions: attribute type (differentiating between issue positions and personal attributes), partisanship (differentiating between characteristics typical of Republicans and Democrats), and evaluative type (differentiating between positively and negatively evaluated attributes). The results of a laboratory study indicate that organization along the attribute type dimension was most common, with some evidence of partisan organization. There was no evidence of organization along the evaluative dimension. The implications of the study for understanding individual differences in political reasoning, and the consequences of memory organization strategies, are discussed.  相似文献

In this paper we develop an econometric model to test whether alienation and/or mobilized voting explain urban-rural turnout in Korea. We find that a person's decision to vote is influenced by the act of mobilization and that it affects rural residents more strongly. But we do not find that the feeling of alienation affects a person's decision to vote. Thus, we find support for the mobilized voting hypothesis, but not for the alienation nonvoting hypothesis.  相似文献
