The imperatives of social democratization and global economic competition have opened a new phase of development for the Korean university and its scholarship. The increased social demands for knowledge creation and dissemination gradually extend the scope of professional practice beyond the conventional areas of academic work. This paper explores, based upon the findings of a case study, how Korean universities and their professors have been responding to these demands and what consequences are observable. It also explains how the new demands and responses are contributing to local development. Finally, it highlights several controversial issues in the discourse on entrepreneurial scholarship and discusses these in the Korean context as points for further investigation. 相似文献

When consumers search for health information, a major obstacle is their unfamiliarity with the medical terminology. Even though medical thesauri such as the Medical Subject Headings (MeSH) and related tools (e.g., the MeSH Browser) were created to help consumers find medical term definitions, the lack of direct and explicit integration of these help tools into a health retrieval system prevented them from effectively achieving their objectives. To explore this issue, we conducted an empirical study with two systems: One is a simple interface system supporting query-based searching; the other is an augmented system with two new components supporting MeSH term searching and MeSH tree browsing. A total of 45 subjects were recruited to participate in the study. The results indicated that the augmented system is more effective than the simple system in terms of improving user-perceived topic familiarity and question–answer performance, even though we did not find users spend more time on the augmented system. The two new MeSH help components played a critical role in participants’ health information retrieval and were found to allow them to develop new search strategies. The findings of the study enhanced our understanding of consumers’ search behaviors and shed light on the design of future health information retrieval systems. 相似文献

This article examined the role of centering in estimating interaction effects in multilevel structural equation models. Interactions are typically represented by product term of 2 variables that are hypothesized to interact. In multilevel structural equation modeling (MSEM), the product term involving Level 1 variables is decomposed into within-cluster and between-cluster random components. The choice of centering affects the decomposition of the product term, and therefore affects the sample variance and covariance associated with the product term used in the maximum likelihood fitting function. The simulation study showed that for an interaction between a Level 1 variable and a Level 2 variable, the product term of uncentered variables or the product term of grand mean centered variables produced unbiased estimates in both Level 1 and Level 2 models. The product term of cluster mean centered variables produced biased estimates in the Level 1 model. For an interaction between 2 Level 1 variables, the product term of cluster mean centered variables produced unbiased estimates in the Level 1 model, whereas the product term of grand mean centered variables produced unbiased estimates for the Level 1 model. Recommendations for researchers who wish to estimate interactions in MSEM are provided. 相似文献

The purpose of this study was to develop an index to assess and evaluate the competitive advantage of a country’s human resource development system. Based on an extensive literature review, a theoretical model of a human resource development system at the national level (named National Human Resource Development: NHRD) was constructed. The model consists of four factors—supply conditions, demand conditions, environment, and supporting systems—and NHRD system competitiveness was measured by the cumulative sum of a country’s achievement in each of these four factors. The four factors were divided into 10 sub-categories, and 45 indicators were selected based on criteria such as relevance, international comparability, reliability, timeliness, and accessibility. Finally, by using the Analytic Hierarchy Process, the individual weights of the 45 indicators were calculated. In addition, the relationships between the NHRD competitiveness scores of OECD member countries and other relevant variables, including GDP per capita and the scores from other national competitiveness studies, were analyzed to examine the validity of the index. 相似文献

AbstractIt is often observed that when sport celebrities are involved in scandals they continue to reap a variety of benefits once the scandal fades. While it may appear they suffer little consequence for their misdeed, consequences do of course ensue. One of these is relative deprivation, particularly for young groups. This study examines how young South Koreans differently shape relative deprivation according to the type of scandal. A sample of 262 Korean university students were subjected to a priming scenario technique that showed examples of Korean sport celebrities’ real scandals. This study finds that Korean university students’ cognition, affect, and behaviour of relative deprivation were positively correlated to one another. Only the behavioural dimension was significantly different according to the type of scandal. The results could be implemented toward customising sport organisation’s communication message and a sport celebrity’s image repairing strategy when the scandal is related to social equity. 相似文献
