A note on “Coordinating a supply chain for deteriorating items with a revenue sharing and cooperative investment contract”

In this short note, we first improve the proof in Zhang et al. [1] to show the strict concavity of the unit time total profit of the whole supply chain with respect to preservation technology investment without approximation. We then generalize the model of Zhang et al. [1] to a broader class of market demand functions. Additionally, theoretical results are provided to illustrate the features of the proposed model.     

论公共政策效能的衰减机制

公共政策效能衰减分为有效衰减和无效衰减两种形式。公共政策效能有效衰减是公共政策效能运行规律的反映,而无效衰减是在公共政策效能没有正常释放的情况下发生的,是影响公共政策目标实现的主要因素。公共政策共同体中,不同行为主体之间行为取向的多元化和行为方式的分散化是公共政策效能无效衰减的主要原因。公共政策共同体中各行为主体以理解为目的的交往活动,是减少公共政策效能无效衰减的重要途径。现有制度设计上的不完善,导致公共权力一定程度上的垄断化、碎片化和异质化,这是造成公共政策效能无效衰减的根本的原因。打造有利于公共政策共同体中各行为主体在平等互动基础上的有效的和全方位、深层次交往的制度性平台,实现公共权力在组织上、资源上和功能上的整合是克服公共政策效能无效衰减的根本途径。     

公共危机管理中的公民参与:价值、困境与路径选择——基于社会资本范式的研究

公民参与是公共危机管理的一个重要问题。社会资本理论是分析社会发展的一种重要理论,对公民参与具有较强的解释力。本文梳理了公民参与、公共危机管理和社会资本的相关概念和内涵,以社会资本为中介和基础分析了公共危机管理中公民参与的价值;在社会资本缺失和负外部性下讨论了公民参与公共危机管理的困境;并通过社会资本的投资和自我完善分析了公民参与公共危机管理的路径选择。     

Coordinating contracts for a financially constrained supply chain

We consider a financially constrained supply chain in which a supplier (leader) sells products to a retailer (follower) who has no access to bank financing due to her low credit rating. However, the supplier can borrow from a bank and offer trade credit to the retailer to alleviate her financial constraint. Failure to pay off a bank loan or trade credit incurs a variable default cost. We analyze the centralized version of the supply chain to obtain new coordination requirements. We then examine whether revenue-sharing, buyback, and all-unit quantity discount contracts can coordinate our supply chain. We show that the all-unit quantity discount contract fails to coordinate. However, the revenue-sharing and buyback contracts can coordinate the supply chain, but only when the supply chain has a sufficient total working capital. Moreover, they cannot allocate profit flexibly unless the supplier has a large enough working capital. Finally, we design a generalized revenue-sharing contract that coordinates the supply chain with flexible profit allocation, and also show by numerical examples its superiority over the revenue-sharing and buyback contracts.     

司法中群体观念的形成机制——司法如何应对民意的前提考量

探究司法如何应对民意,就必须加强对民意形成过程的认识和理解."群体极化"理论对网络时代的民意形成机制有较强的解释力.理论上,群体极化效应主要由两个机制形成:名誉机制和信息机制.中国因其国情也给群体极化效应提供了特殊要素,尤其是互联网时代的交流模式加剧了群体观念极化的频繁发生.本文以论述"群体极化效应"为主线,加入对关于民意形成机制的其他成果的简单综述,以期能够引起法学界对民意本身的重视.     

Laying the foundation for a global body of knowledge in public relations and communications management

An internationally recognised body of knowledge is both possible and necessary for the future success and professionalisation of public relations. Through extensive content analysis of 31 credential schemes, education frameworks, and scholarly articles produced across six continents, the Global Alliance for Public Relations and Communications Management has developed a foundational list of knowledge, skills, abilities and behaviours (KSABs), which entry and mid/senior-level practitioners across the world should possess. This study and list of KSABs is laying the foundation for development of an internationally accepted framework which professional associations and academic institutions across the world will be able to use to benchmark professional credentials and curriculum outcomes.     

Examining signs of recovery: How senior crisis communicators define organizational crisis recovery

Interviews with senior crisis communicators explore how crisis recovery is defined and what role publics and organizational communication and characteristics play. Findings reveal recovery is measured operationally and short-term. Effective communication proactively addresses failures, is transparent and honest while positive, focuses on future directions, and rebuilds and repairs symbolic damage. Organizational best practices include tested values and crisis leadership. Publics can facilitate healing, highlight victims’ voices, and provide recovery evidence.     

Business patterns within telecommunications

The global telecommunications changed from a number of co-operating national monopolies offering a restricted range of services to a competitive, growing market with players of many types and sizes, offering a large range of services. How can vertically integrated incumbents align themselves and their systems to best compete in this environment? Business patterns and enterprise modelling offer a tool to model a large organization as a number of smaller enterprises that can compete with and co-operate with smaller specialist players in the market. In order to identify enterprises, this paper proposes that there are only a limited number of types of enterprise (manufacturer, service supplier, reseller, that these enterprise types can only interact in a limited number of ways (component supply, aggregation supply, resell supply, trading, end-supply and commission). With the use of examples, this paper illustrates these types of enterprise and enterprise relationships, and how they can be combined to build both internal and external supply chains, and discusses some of the conclusions that can be drawn from this analysis.     

Determinants of consistent,timely, and active responses in corporate crises

This paper investigates the individual and combined factors affecting the extent to which corporations respond to crisis events consistently, in a timely manner, and actively. The determinants examined include public relations autonomy, legal dominance, strategic orientation, and organizational factors. A survey was conducted of communications mangers, public affairs personnel, and public relations personnel, drawn from the top 500 companies operating in Taiwan. Results indicate that the relative effect of individual sources of influence on crisis response is greatest for situations in which public relations departments have the most autonomy, followed by those where crisis management is handled with a strategic orientation, those where the legal departments dominate, and those where organizational factors provide the main avenue of address. The results emphasize the intriguing role of public relations autonomy by demonstrating its significant impact on providing a consistent, timely, and active crisis response. The strategic orientation of situation analysis also predicts a consistent response, whereas legal dominance predicts strategic ambiguity or inconsistent communication.     

Keep Your Friends Close? Supply Chain Design and Disruption Risk

In this article, we evaluate the relationship between supply chain design decisions and supply chain disruption risk. We explore two supply chain design strategies: (i) the dispersion of supply chain partners to reduce supply chain disruption risk versus (ii) the co‐location of supply chain partners to reduce supply chain disruption risk. In addition, we assess supply chain disruption risk from three perspectives: the inbound material flow from the supplier (supply side), the internal production processes (internal), and the outbound material flow to the customer (customer side) as a disruption can occur at any of these locations. We measure disruption risk in terms of stoppages in flows, reductions in flow, close calls (disruptions that were prevented at the last minute), disruption duration (time until normal operation flow was restored), and the spread of disruptions all the way through the supply chain. We use seemingly unrelated regression (SUR) to analyze our data, finding that lead times, especially supply side lead times, are significantly associated with higher levels of supply chain disruption risk. We find co‐location with suppliers appears to have beneficial effects to the reduction of disruption duration, and, overall supply side factors have a higher impact when it comes to supply chain disruption risk than comparable customer side factors.
