英格兰数理精英教师培养及启示——基于“未来教学学者”计划

英格兰政府针对国内中小学数学和物理等学科专业教师紧缺、学生数理成绩较差的现状，推出了"未来教学学者"（Future Teaching Scholars）精英教师培养计划。这一专项教师培养计划旨在通过严格的选拔标准、系统的培养方案、丰厚的奖学金与助学金以及明确的教师未来职业发展规划，吸引高质量的本科生积极参与，从而提高英格兰数理学科教师的专业水平及学生的数理学科成绩。英格兰政府为改善特定科目和偏远地区学校教师质量而开展的专项教师培养项目为我国相关教师的培养工作提供了积极借鉴：创新教师教育培养模式，提高师范生教学实践能力；充分发挥地方师范院校的主体作用，保障特定地区教师供应；提高师范生选拔标准，促进教师队伍整体质量提升。     

基于消费者效用的生鲜农产品供应链生鲜度激励机制研究

生鲜供应链整体生鲜度的提升对减少浪费、提高供应链整体盈利水平及社会福利有重要意义。本文基于消费者效用理论研究了两供应商和单一零售商组成的供应链系统，构建了单周期下生鲜农产品生鲜度激励模型，模型以供应商为领导者，采用Stackelberg博弈方法求解得到了均衡状态下供应商、零售商的最优定价策略及供应商新鲜度努力选择。研究结果表明，供应商和零售商利润与消费者价格敏感系数呈反向变化，与新鲜度敏感系数呈同向变化。在价格竞争市场，供应商保鲜努力程度和利润与价格替代率呈反向变化；在生鲜度竞争市场，供应商保鲜努力程度和利润与新鲜度替代率呈同向变化。基于研究结论，厂商及政府应当联手引导消费者的消费观念，尽可能减少由于信息不对称引致的道德风险，在市场价格替代率不变甚至降低的情形下，提高生鲜度替代率，使得消费者的意愿支付价格上升，提高自身讨价还价能力，获取更多利润。

“印太”背景下的印日合作

"印太"概念经历了从地缘术语向战略构想的演变,且域内各国基于本国利益塑造"印太"构想的进程尚未结束,这使得相关研究需要不断转换视角并注重动态追踪。莫迪执政后,印度和日本升级两国战略伙伴关系,完善各层级对话机制,共同推动区域连通性与基础设施建设,并提出"亚非增长走廊"愿景。在深化海洋安全合作的基础上,实现军事演习全面覆盖与装备技术合作的纵深发展,注重地区问题的立场协调与强化美印日、美印日澳等多边磋商机制。"印太"发展契机、两国战略目标驱动、制衡中国需求以及美国战略推动构成了印日战略合作的基本动因。得益于双方战略对接的深入和适宜的国内政治环境,印日深化战略合作的势头还将持续,表现在防务合作模式的多元化和加速布局"印太"基建项目的趋势。国内条件限制、"印太"战略差异以及国际局势影响等制约性因素也给两国合作前景带来挑战。     

Crowdfunding digital platforms: Backer networks and their impact on project outcomes

Crowdfunding platforms serve to connect project creators and backers. Previous research has explored several project and platform determinants that impact crowdfunding outcomes. However, there has been limited research on these determinants at an individual level. Our paper addresses how backers may influence the outcomes of projects in crowdfunding platforms. We explore several methods commonly used in the industry to identify influence and show that centrality measures through a backer affiliation network best exemplifies influence. Using data from Kickstarter, we construct a weighted backer network based on 52,678 common projects backed by 11,134 backers. Controlling for digital media mentions and project quality, we find evidence that backers in central positions within the network have a positive impact on multiple project outcomes such as the project success rates, amount of funds raised, speed of reaching the crowdfunding goal as well as the number of backers contributing to the project. These findings are replicated and reinforced by using data from a different crowdfunding platform using the entire backer network based on 1095 projects backed by 87,896 backers. Several robustness tests are used to validate these results.

Social Contexts and Coping Strategies of Foreign Wives in Korea: Using a Conceptual Framework of Social Identity Theory

This study aimed to address the social contexts of Korean society in which diverse social interactions of foreign wives take place and to identify coping strategies to construct positive social identities. Social identities are often reconstructed as a result of dynamic interactions with various situations. Using the conceptual framework of social identity theory, this study attempted to uncover the social contexts that shape foreign wives' social identities. This study, using the qualitative approach, selected nine Filipino and Vietnamese participants who were married to Korean men. The data were collected by in‐depth interviews, a focus group with three Vietnamese participants, field notes, participant observation, and photo documents. In the section on study findings, this study addressed Korean social contexts, in which Korean government has been providing a variety of multicultural policies and services for helping foreign wives successfully adapt to Korea. This study also found various forms of stereotypes and discrimination against foreign wives and presented their discrimination experiences. Diverse ways to cope with such negative experiences are presented in the last section. Given the findings, the researcher suggests that policies and programs should promote foreign wives' integration in Korean society.

Optimal control strategies for dividend payments and capital injections in compound Markov binomial risk model with penalties for deficits

We consider the compound Markov binomial risk model. The company controls the amount of dividends paid to the shareholders as well as the capital injections in order to maximize the cumulative expected discounted dividends minus the discounted capital injections and the discounted penalties for deficits prior to ruin. We show that the optimal value function is the unique solution of an HJB equation, and the optimal control strategy is a two-barriers strategy given the current state of the Markov chain. We obtain some properties of the optimal strategy and the optimal condition for ruining the company. We offer a high-efficiency algorithm for obtaining the optimal strategy and the optimal value function. In addition, we also discuss the optimal control problem under a restriction of bounded dividend rates. Numerical results are provided to illustrate the algorithm and the impact of the penalties.     

Revisiting the effectiveness of the employment‐oriented welfare state: Considering the quality of employment achievement

The purpose of this study was to examine the effectiveness of an employment‐oriented welfare state. While previous studies have focused on employment growth, this study considers the quality of employment, especially its mediating impact between public social expenditure and fiscal soundness. Three‐step mediated regression analysis was conducted on a data sample from 19 developed countries from 1991 to 2013. The results show that while public social expenditure negatively affects fiscal soundness, if it promotes total and part‐time employment, it can positively affect fiscal soundness. However, when the incidence of involuntary part‐time employment is high, public social expenditure and its impact on employment performance no longer guarantee fiscal soundness. This study addresses the importance of promoting not only employment growth but also employment quality to secure fiscal soundness.
