“不期而寓”--青年城市配套综合体可行性调研报告

随着时代发展,独居、年轻化已成为租房人群的关键词。观念的升级和住房租赁政策的完善,使得90后的置业观悄然改变。经过市场调查,市面上还没有针对大学毕业生这一群体的长租公寓,多数是针对有一定经济能力的上班族。因此,大学毕业生的住房需求仅仅通过政府采取措施远远无法满足。论文从国家的宏观政策及市场微观细分因素中的人口因素、地理因素、行为因素等方面对“不期而寓”——青年城市配套综合体进行了分析,为项目的推进提供可靠的数据和科学性支持。

Which school systems sort weaker students into smaller classes? International evidence

We examine whether the sorting of high- and low-achieving students into classes of different sizes results in a regressive or compensatory pattern of class sizes for 18 national school systems. Sorting effects are identified by subtracting the causal effect of class size on performance from their total correlation. Our empirical results reveal strongly compensatory patterns of sorting within and especially between schools in many countries. Only the United States, which has a decentralized education finance and considerable residential mobility, exhibits regressive between-school sorting. Between-school sorting is more compensatory in systems with ability tracking. Within-school sorting is more compensatory where administrators rather than teachers assign students to classrooms.     

Optimizing the credit term decisions in supply chain finance

We study a credit term determination problem in the context of a supplier-buyer supply chain. The supplier's credit term decision is simultaneously made with its production and inventory decisions, and most importantly, it is impacted by the buyer's order quantity. We present a new game-theoretic framework to model this problem, which captures the interaction between the supplier's credit term decision and the buyer's order decision in a multi-period setting. An exact method based on nonlinear programming is implemented to obtain the optimal solutions. We apply our methodologies on a real world case. The computational results show that our approach significantly outperforms the heuristics with fixed credit terms, and either a short or a long credit term can be sub-optimal for the supplier in profitability. Our work offers the first data-driven model and solution approach that assists purchasing and supply managers to make optimal dynamic credit term decision in conjunction with production, ordering and inventory decisions in a game-theoretic setting.     

高校科普研究进展

高校为高等院校的简称。高校科普就是指高等院校的组织、机构和个人利用高校的设施、设备和人员开展的科普活动与行为。通过检索新世纪以来我国高校开展科普研究的文献,发现我国高校科普研究多集中于实践层面,理论研究较为少见。实践研究多是从高校科协工作、高校博物馆（档案馆、标本馆和图书馆）开放、高校科普教育基地建设工作和面向高校师生开展科普工作、高校科普创作的重要意义、实施策略（方式）以及机制等内容。高校科普基础理论研究的文章较少,主要体现在高校科协建设理论、高校科普内涵、科研科普的关系等内容。综合来看,高校科普研究内容较多,但是深入不够;实践研究多,理论研究少;实践研究多集中于方式方法研究,而机制和途经研究少;从发展的角度看,高校培养科普人才、高校科普志愿者研究、高校科普创作研究和高校科研科普关系研究将会成为未来的研究热点。     

The impact of relative residence times on the distribution of heavy drinkers in highly distinct environments

Alcohol consumption is a function of social dynamics, environmental contexts, individuals' preferences and family history. Empirical surveys have focused primarily on identification of risk factors for high-level drinking but have done little to clarify the underlying mechanisms at work. Also, there have been few attempts to apply nonlinear dynamics to the study of these mechanisms and processes at the population level. A simple framework where drinking is modeled as a socially contagious process in low- and high-risk connected environments is introduced. Individuals are classified as light, moderate (assumed mobile), and heavy drinkers. Moderate drinkers provide the link between both environments, that is, they are assumed to be the only individuals drinking in both settings. The focus here is on the effect of moderate drinkers, measured by the proportion of their time spent in “low-” versus “high-” risk drinking environments, on the distribution of drinkers.A simple model within our contact framework predicts that if the relative residence times of moderate drinkers are distributed randomly between low- and high-risk environments then the proportion of heavy drinkers is likely to be higher than expected. However, the full story even in a highly simplified setting is not so simple because “strong” local social mixing tends to increase high-risk drinking on its own. High levels of social interaction between light and moderate drinkers in low-risk environments can diminish the importance of the distribution of relative drinking times on the prevalence of heavy drinking.
