以环境污染指数作为非期望产出,基于SBM方向性距离函数,测度我国30个省份2000年至2018年工业Malmquist-Luenberger指数,并将工业全要素生产率变化指数进行分解,进一步分析出工业技术进步的投入要素偏向性与产出偏向性,从中探索其变动与区域分布特点.结果表明,我国工业TFP持续增长,但增长幅度逐渐下降;TFP增长主要依靠工业技术进步,工业产业效率有待改善;东部地区技术进步偏向于使用资本要素,中西部地区偏向于使用劳动要素;TC变动与MATC变动一致,规模技术进步为拉动技术进步的主要动力,其次是投入偏向型技术进步,最后是产出偏向型技术进步;东部和中部地区技术进步偏向于促进期望产出,西部地区技术进步加重了环境污染.最终结合实证分析给出相关对策.  相似文献

ABSTRACT

For higher education graduates to be effective in the workplace, they require strong technical skills and the capability to operate across diverse knowledge landscapes to solve real world problems. At an Australian university, an interdisciplinary, short-term study tour programme was utilised to enhance students’ inexplicit employability skills with a focus on managing complexity while developing agility and creativity. To investigate the effectiveness of such a programme, we examined students’ perceptions of an interdisciplinary teamwork assessment task that was undertaken in an international context via a study tour model. We achieved this by, first, introducing a purposely designed interdisciplinary teamwork assessment task, which focused on students presenting innovative ideas to peers and industry members. Second, we elicited student responses via a case study approach that incorporated mixed methods, utilising several data collection instruments prior to, during, and after students participated in a study tour. The findings suggest that integrating a purposely designed interdisciplinary teamwork assessment task, via a short-term study tour model, uncovered certain inexplicit employability skills, namely managing complexity, developing agility and creativity. We make specific recommendations to support this insight, contributing to the mobility teaching and learning research field.  相似文献

The purpose of this research is to illustrate the use of the gamma distribution to model the ages of references in published research, and to demonstrate that the two gamma distribution parameters characterise a field of research in a manner that is complementary to and more nuanced than the Price Index or mean age of references.Minimum Distance Estimation is shown to produce robust estimates of the gamma distribution parameters because of the insensitivity of the Kolmogorov–Smirnov test in the tails of the distribution.Using a sample of 816 articles from 26 different journals across six subject areas, it is shown that the gamma distribution is at least as good as a lognormal distribution to model the ages of references in research articles.The two gamma distribution parameters indicate the rate of publication of new knowledge within the respective discipline and the citing behaviour in terms of the recency of references. Interpretation of these gamma distribution parameters enables a more nuanced and granular interpretation of the distinctiveness of disciplines, sub-disciplines, formats of publication and the distribution of references within articles than possible using the Price Index, half-life or mean age of references.  相似文献

We test acculturative stress, Hybrid (HIS) and Alternating (AIS) Identity Styles, and their interaction effects as predictors of psychosocial functioning over a 12-day period among Hispanic American university students. Participants completed measures of acculturative stress, HIS, AIS, and internalizing (anxiety and depression) and externalizing (social aggression and rule-breaking) symptoms on Day 1; on Day 12 they completed the symptom measures a second time. Structural equation modelling was used to examine the Day 1 effects of acculturative stress, cultural identity styles, and their interactions on Day 12 symptoms controlling for the Day 1 symptoms. We hypothesized that acculturative stress would predict more, and the HIS would predict fewer, symptoms and that the AIS would moderate the relationship between acculturative stress and symptoms over time. Results indicated that: (1) acculturative stress predicted an increase in internalizing symptoms; (2) the HIS predicted a decrease in internalizing and externalizing symptoms; and (3) the AIS attenuated the relationship between acculturative stress and externalizing symptoms. The results are discussed in relation to the distinctive features of internalizing and externalizing symptoms, and recommendations for future research are advanced.  相似文献

This study investigated understandings of national group belonging in relation to attitudes toward foreign and established outgroups in Mauritius. Representative data were collected among the three numerically largest ethno-cultural groups (Hindus, Muslims, and Creoles; Ntotal = 1770) and results confirmed a distinction between “being,” “doing,” and “feeling” Mauritian among all three groups, with some small differences for Creoles compared to Hindus and Muslims. Furthermore, “being” Mauritian was not significantly related to attitudes toward established and foreign outgroups. In contrast, the “doing” understanding was negatively associated with both attitudes, and the “feeling” understanding showed positive associations with both outgroup attitudes among all three participant groups. The findings make a novel contribution to the literature on how people understand national identity, how these understandings differ between ethno-cultural groups within a nation, and how these relate to attitudes toward foreign as well as established outgroups.  相似文献
