Taiwan has made significant progress in the semiconductor industry with government agencies and bureaucrats as the driving forces over the past 30 years. Taiwan's impressive achievement in the semiconductor industry clearly indicates that the government failures and agency problem usually associated with deep government involvement did not occur in Taiwan. Why is that the case? This paper proposes a principal-agent framework for technology policy and applies the framework to discuss the institutional arrangements through which bureaucrats were controlled effectively in executing the semiconductor industry policies in Taiwan. By analyzing the institutional and organizational arrangements Taiwanese leaders made to mitigate the agency problem, this paper brings bureaucrats into the popular developmental state theory and emphasizes that the success of state intervention should not be taken for granted, and it also brings politics into technology policy analysis and stresses the importance and complexity of agency problem in technology policy. 相似文献

Clusters,convergence, and economic performance 总被引:1,自引:0,他引:1
This paper evaluates the role of regional cluster composition in regional industry performance. On the one hand, diminishing returns to specialization in a location can result in a convergence effect: the growth rate of an industry within a region may be declining in the level of economic activity of that industry. At the same time, positive spillovers across complementary economic activities can provide an impetus for agglomeration: the growth rate of an industry within a region may be increasing in the “strength” (i.e., relative presence) of related industries. Building on Porter (1998, 2003), we develop a systematic empirical framework to analyze the role of regional clusters – groups of closely related industries operating within a particular region – in the growth of regional industries. We exploit data from the US Cluster Mapping Project to examine the effects of agglomeration within regional clusters after controlling for convergence at the region-industry level. Our findings suggest that industries located in a strong cluster register higher employment and patenting growth. Regional industry growth also increases with the strength of related clusters in the region and with the strength of similar clusters in adjacent regions. We also find evidence of the complementarity between employment and innovation performance in regional clusters: both the initial employment and patenting strength of a cluster have a separate positive effect on the employment and patenting growth of the constituent industries. Finally, we find that new regional industries emerge where there is a strong cluster. These findings are consistent with multiple types of externalities arising in clusters, including knowledge, skills, and input–output linkages. 相似文献

Abstract In this paper, I present data from two studies that sought to examine multiple achievement goals in the context of children's physical education (PE). Study 1 examined the links that multiple-goal profiles (i.e. mastery/performance-approach/performance-avoidance goals) for PE had with self-determined motivation, affective patterns and levels of extracurricular sporting activity in a sample of 193 Year 7 pupils. Results suggested that children endorsing high mastery/high performance-approach/high performance-avoidance, high mastery/high performance-approach/low performance-avoidance, or high mastery/ low performance-approach/low performance-avoidance profiles typically exhibited the most adaptive motivational responses. In contrast, children endorsing a low mastery/high performance-approach/high performance-avoidance profile typically experienced more maladaptive motivational outcomes. Study 2 examined the development of multiple achievement goals over two terms of PE in conjunction with retrospective perceptions of the motivational climate in the sample. The results of analysis of variance suggested that children exposed to a consistent high mastery/low performance climate experienced decreased performance-avoidance goals and maintained high levels of mastery goals for PE. In contrast, children exposed to a consistent low mastery/high performance climate experienced increased performance-avoidance goals and decreased mastery goals for PE. 相似文献

An exploratory survey of Assistants in Scottish educational psychology services (EPSs) was undertaken, guided by four questions: Who are Assistants? Why are they employed/not employed? What do Assistants do? How are Assistants supported and supervised? Twenty-one Assistants and 15 managers were interviewed. It was found that Assistants worked under seven job titles; all were committed to becoming educational psychologists (EPs). Recruitment issues and improving EPS research capacity were drivers for employment. The Assistants’ roles were largely research based; however a majority worked directly with young people. Induction and supervision were valued but not consistent. Further discussion includes issues of competence and remit, and the relationship of Assistant and professional role. 相似文献

In anatomical education three-dimensional (3D) visualization technology allows for active and stereoscopic exploration of anatomy and can easily be adopted into medical curricula along with traditional 3D teaching methods. However, most often knowledge is still assessed with two-dimensional (2D) paper-and-pencil tests. To address the growing misalignment between learning and assessment, this viewpoint commentary highlights the development of a virtual 3D assessment scenario and perspectives from students and teachers on the use of this assessment tool: a 10-minute session of anatomical knowledge assessment with real-time interaction between assessor and examinee, both wearing a HoloLens and sharing the same stereoscopic 3D augmented reality model. Additionally, recommendations for future directions, including implementation, validation, logistic challenges, and cost-effectiveness, are provided. Continued collaboration between developers, researchers, teachers, and students is critical to advancing these processes. 相似文献

Mappings between the structure and function of a system or device affect the formation of accurate mental models. This study
investigated the performance effect of a more natural cognitive mapping between instruments and aircraft on an aircraft instrument
comprehension (AIC) task. Treatments for the experimental groups were identical except that aircraft instrument displays were
modified slightly to incorporate natural and unnatural mappings between structure and function. Students who received natural
mappings during instruction performed significantly better than those who received the standard treatment containing an unnatural
mapping. Questionnaire responses confirmed the difficulty of interpreting the standard treatment. The results suggest that
instruction for the AIC and similar tasks should be expanded to take into account learners' mental models and perhaps to encourage
mapping strategies. 相似文献

ABSTRACTA body of literature on students as partners (SaP) in higher education has emerged over the last decade that documents, shares, and evaluates SaP approaches. As is typical in emerging fields of inquiry, scholars differ regarding how they see the relationship between the developments in SaP practices and the theoretical explanations that guide, illuminate, and situate such practices. In this article we explore the relationship between theory and practice in SaP work through an analysis of interpretive framing employed in scholarship of SaP in teaching and learning in higher education. Through a conceptual review of selected publications, we describe three ways of framing partnership that represent distinct but related analytical approaches: building on concepts; drawing on constructs; and imagining through metaphors. We both affirm the expansive and creative theorising in scholarship of SaP in university teaching and learning and encourage further deliberate use and thoughtful development of interpretive framings that take seriously the disruptive ethos and messy human relational processes of partnership. We argue that these developmental processes move us toward formulating theories of partnership praxis. 相似文献

Counseling interventions that support the exploration of ethnocultural concerns are beneficial to the overall well‐being of Black women in college. The authors describe Cultural Connections, a theoretically based and culturally adapted group counseling intervention for Black women in college. Also presented are a case example demonstrating the intervention's utility and recommendations for implementation in college counseling centers. 相似文献
