基于优先权拍卖的产能分配机制研究

本文考虑一个供应商和两个独立零售商构成的供应链系统。当供应商的产能受到约束时，零售商可能会竞争有限的产能。本文提出将“优先分配权”作为一个有价值的标的物进行拍卖，按照出价高低确定优先分配顺序。本文证明了优先权拍卖机制属于共同价值模型，并提出了两类拍卖机制：事先拍卖和事后拍卖。本文证明两类优先权拍卖机制均会促使零售商提交真实的需求作为订单量，并且满足收益等价定理。而就供应商期望利润而言，事后优先权拍卖机制要高于事先优先权拍卖机制。     

National Language Capacity in Global Competition

The term national language capacity refers to the sum total of a nation’s ability to grasp linguistic resources, provide language services, deal with linguistic issues, develop the language, and related tasks. Key capacities include the possession of linguistic resources, utilization of language and language services, development and use of linguistic resources, the language of the members of the nation, reserves of linguistic talent, language management, development of language enterprises and linguistic influence. The development of informatization has made national language capacity an important part of national strength. It is hard power as well as soft power, playing a very important role in social progress and cultural inheritance, in promoting economic development and technological innovation, and in protecting a country’s national security and international development.     

Open Data on a Closed Shop? Assessing the potential of transparency initiatives with a focus on efforts to strengthen capacity development support

Despite strong political commitment, actual gains in improving accountability in development co‐operation have been limited. Main reasons for this include the low level of transparency and high number of actors, as well as the limitations of the self‐reported and input‐oriented OECD reporting system. Efforts through the International Aid Transparency Initiative (IATI) and related transparency initiatives are ill‐equipped to change this given their decision to adhere to the same system. This article uses the specific area of support to capacity development to illustrate this. While further disaggregation of reporting on technical co‐operation could respond to a transparency gap, overcoming the accountability gap requires moving beyond promoting ‘supply‐side’ reform and re‐engaging in efforts to promote collective action.     

An evaluation capacity building toolkit for principal investigators of undergraduate research experiences: A demonstration of transforming theory into practice

This paper describes the approach and process undertaken to develop evaluation capacity among the leaders of a federally funded undergraduate research program. An evaluation toolkit was developed for Computer and Information Sciences and Engineering¹ Research Experiences for Undergraduates² (CISE REU) programs to address the ongoing need for evaluation capacity among principal investigators who manage program evaluation. The toolkit was the result of collaboration within the CISE REU community with the purpose being to provide targeted instructional resources and tools for quality program evaluation. Challenges were to balance the desire for standardized assessment with the responsibility to account for individual program contexts. Toolkit contents included instructional materials about evaluation practice, a standardized applicant management tool, and a modulated outcomes measure. Resulting benefits from toolkit deployment were having cost effective, sustainable evaluation tools, a community evaluation forum, and aggregate measurement of key program outcomes for the national program. Lessons learned included the imperative of understanding the evaluation context, engaging stakeholders, and building stakeholder trust. Results from project measures are presented along with a discussion of guidelines for facilitating evaluation capacity building that will serve a variety of contexts.     

Implementation of a school-wide prevention programme-teachers’ and headmasters’ perceptions of organizational capacity

This study focuses on schools’ organizational capacity to implement a Swedish school-wide programme, Prevention in School (PS). It is based on semi-structured interviews with seven headmasters and 13 teachers from seven Swedish schools. The interviews were analyzed by the use of qualitative content analysis.The findings show that the adoption of a comprehensive intervention like PS challenges the school organization as the staff encountered a variety of organizational barriers when implementing the programme. Factors connected to lack of consensus, collaboration and insufficient programme management were the main barriers that were identified. Teachers wanted a more extensive support from their headmasters in terms of participation in different programme activities. It was emphasized that peer coaches need to be prepared for their task, although the headmasters found it difficult to be able to choose those teachers who they perceived as the most suitable.It is concluded that leadership, coaching and staff selection need particular attention when implementing a programme like PS, since those factors have been defined as important implementation drivers, both in this study and previously.     

论竞争条件下多销售渠道并存的航空货运舱位控制问题

在航空货运市场竞争日趋激烈的环境下，基于竞争的收益管理问题已经成为管理科学界的研究热点之一。针对竞争条件下的两个航空货运公司两个舱位的容量控制问题，利用博弈论的方法，建立了代理市场和现货市场并存时两公司两子舱的水平竞争的三方博弈模型，并详细分析了在 Stackelberg博弈中货运代理商的最优订购决策以及两个航空货运公司在 Cournot 博弈中的最优反应函数的性质。结果表明：如果在位者不在代理市场上销售运力，那么进入者也绝对不会提供代理市场的舱位，也就是说，如果在位者没有动力提供代理市场的运力，则代理市场将不会存在。     

大学生专业操作能力优化教学模式的构建——以人力资源管理专业课程为例

高校人才培养与企业实际需求存在匹配度较低的问题,因而有必要构建新的大学生专业操作能力优化教学模式.新的教学模式涵盖目标描述、目标支撑、流程管理、经验教训、工具与表单五个方面.它可以让学生的学习从抽象到具体,从理论到实践,从宏观到微观,从被动接受到主动思考,达到对该模块更深刻的学习、掌握与运用,从而更加适应企业与社会的需求.

Signaling to Partially Informed Investors in the Newsvendor Model

We analyze a signaling game between the manager of a firm and an investor in the firm. The manager has private information about the firm's demand and cares about the short‐term stock price assigned by the investor. Previous research has shown that under continuous decision choices and the Intuitive Criterion refinement, the least‐cost separating equilibrium will result, in which a low‐quality firm chooses its optimal capacity and a high‐quality firm over‐invests in order to signal its quality to investors. We build on this research by showing the existence of pooling outcomes in which low‐quality firms over‐invest and high‐quality firms under‐invest so as to provide identical signals to investors. The pooling equilibrium is practically appealing because it yields a Pareto improvement compared to the least‐cost separating equilibrium. Distinguishing features of our analysis are that: (i) we allow the capacity decision to have either discrete or continuous support, and (ii) we allow beliefs to be refined based on either the Undefeated refinement or the Intuitive Criterion refinement. We find that the newsvendor model parameters impact the likelihood of a pooling outcome, and this impact changes in both sign and magnitude depending on which refinement is used.     

发电成本垂直差异电力市场概率发电——基于大用户电量偏好视角

针对碳减排后普遍存在的发电成本垂直差异电力市场及其显著的大用户电量偏好差异,本文提出概率性电量供给以及与之对应的概率发电,并利用价格杠杆调控发电商低碳发电尤其高发电成本发电机会与供给效能不足.先后构建发电成本内、外生选择下的概率发电模型,求解发电商的电量供给均衡并分析概率发电策略的最优性.最后,将发电成本内生选择模型拓展到分解市场需求不确定性的概率发电模型.研究发现:相比基准发电,概率发电可以作为一种有利可图的发电容量过剩的解决方法,即使在发电成本内生选择时也是可行的;当发电商采用“强”成本差异的发电策略时,引入折中的概率发电会让产品线上成本水平相互更接近,且大用户的消费者剩余得到提高;与此相反,在市场中实施“弱”成本差异发电,发电商利用概率发电则增大成本分离并降低大用户的消费者剩余;在不确定性市场需求下,当偏好低发电成本电量的大用户对单位发电成本的估价相对于偏好高发电成本电量的大用户对单位发电成本的估价足够高时,概率发电可以以一种管理不利需求状况工具的身份出现.
