论体育教学过程中学生主体地位实现的途径

新课改要求在教学活动中要突出学生学习过程中的主体性,课堂应该是以学生为主角,教学过程应围绕学生进行施教。文章通过文献资料、逻辑推理、专家访谈等方法,对当下体育教学过程中学生主体地位的实现途径进行研究。     

EVOLVING A THEORY OF PERFORMANCE‐BASED LOGISTICS USING INSIGHTS FROM SERVICE DOMINANT LOGIC

Performance‐based logistics (PBL) represents a strategy for sustaining complex systems following production. Despite several implementations, limited understanding exists regarding PBL and its implications. Research using grounded theory emerged a theoretical framework for PBL. Service dominant logic (SDL) is introduced as a theoretical lens for interpreting the results and understanding how trading partners achieve performance‐based outcomes.     

Retailers’ incentives for green investment in differentiated competition channels

With increasing public environmental awareness, green activities in retail and distribution processes have become crucial tools for retailers to boost demand and enhance competitiveness. This study develops an analytical model to study the green investment choices of two differentiated retailers dealing with a common green manufacturer. It also explores the impacts of these investment choices on the manufacturer's operational decisions, channel efficiency, consumer welfare, and the environment. We derive three main results. First, the powerful retailer always favors green investments, whereas the less powerful (inferior) retailer may either prefer or avoid green investments. The fiercer the inter-retailer competition, the lower the willingness of the inferior retailer to introduce green investments. Second, although all supply chain parties may disagree on their preferences for retailers' green investments, a bilateral green investment (i.e., both retailers make green investments) can reach an incentive alignment for all firms if the differentiation between retailers is low enough and the competition between them is not substantially fierce. Moreover, a bilateral green investment improves consumer welfare and channel efficiency because of the great demand expansion and double marginalization reduction. Third, the retailers' green investments can motivate the manufacturer to produce greener products, but they do not necessarily benefit the environment. We show that the supply chain's economic sustainability aligns with its environmental sustainability only if the environmental improvement efficiency of green investments is substantially high. We further examine the impact of retailers with differentiated green investment abilities and the manufacturer's green investment efficiency to verify the robustness of the main results.     

Dominant design or multiple designs: the flash memory card case

Literature suggests that in battles between competing designs, ultimately one design will emerge as dominant to the detriment of the others. Various factors and forces have been identified to explain this phenomenon. Yet, sometimes no dominant design emerges at all and multiple competing designs coexist in the market. The flash memory card industry provides an example of this. In this study, we use this example as a case to investigate the circumstances under which an industry has a tendency toward multiple designs. The case shows that a combination of factors may result in multiple designs and we argue that such a combination of factors will increasingly also apply in other cases.

职业技术教育中的教师主导地位与教育质量的思考

职业技术教育的发展和面临的挑战,改变了从事职业技术教育的教师的教学思维方式和教学方法,这种改变对教学产生了积极影响。职业技术教育管理和教学方法的深刻变革,也产生一些值得商榷和探讨的教学方法和管理模式。尽管它们不是教学过程的主流,但是它们对教学活动和教学效果的影响是十分深远。如何让职业技术院校的学生通过几年理论知识和专业技能的学习获得适应社会的能力和技术,是从事职业技术教育的教师主要的课题。
