基于交通量风险的PPP交通项目再融资产品设计

交通PPP项目的投资大、风险高。政府作为发起方,需要为项目提供担保以吸引社会资本方的参与,但过度依赖政府担保意味着：一旦发生数额较大的债务违约将会给财政造成巨大的负担,因此有必要谋求适宜的市场化融资渠道。为了协调PPP项目相关者的利益,本文在项目收益债的基础上嵌入了与项目未来收益挂钩的或有条款,并运用结构化方法中的Merton模型在风险中性情景下对融资产品进行了定价。最后,以某PPP交通项目为例,进行了具体的融资产品设计,计算了相应的产品价格和风险价差,并对某些关键条款进行了敏感性分析,结果表明该产品能够在有效减轻政府担保的基础上降低融资成本。     

不同减排合同下企业间纵向持股对供应链决策的影响

本文针对节能服务公司融资难、回款难及其与用户之间缺乏信任等现象,结合实际中节能服务公司与制造企业采取的不同减排合同机制,分别构建了减排效益分享型合同和减排量保证型合同下企业间纵向持股的三级低碳供应链模型,并对比分析了不同减排合同下持股策略对供应链企业决策及利润的影响。通过模型分析并结合案例及数值算例发现,在减排效益分享型合同中,当制造商单独持股节能服务公司时,增加持股比例会使产品减排量和链条上其他成员利润增加,同时低碳产品市场价格增加;当零售商和制造商同时持股节能服务公司时,两公司增加持股比例同样会使企业决策和利润得到优化,实现真正意义上的供应链企业大联盟,但该种情形会加大持股比例与企业决策和利润的协调难度。此外,在减排效益分享型合同下,制造商对节能服务公司持股可使环保红利和企业效益均得到增加,建议此种减排模式下的供应链企业实施持股策略;但对于减排量保证型合同,持股策略对各企业决策及利润并无明显改善,因此该种减排合同下不建议企业间采取股权合作策略。     

Interfamily economic exchange: A function of culture or economics?

This study explores differences in inter-household exchange of goods and services in Anglo- and Mexican-American families controlling for income level and for ethnicity. The extent of such exchange, its perceived importance to the family's quality of life, satisfaction with the exchange, and the relation of persons in the exchange process are examined. Significant differences are found more often between higher income Anglo- and Mexican-Americans than between low-income families, both in the family providing goods and services for others and in the receipt of them. Higher income Mexican-American families are more likely than their Anglo- counterparts to exchange with relatives. Ethnic effects are more prevalent in higher income households than in low-income households. Economic effects are more predominant than ethnic effects.This study contributes to interregional Agricultural Experiment Station Research Project NC-128, Quality of Life as Influenced by Area of Residence. Cooperating states: Arizona, California, Colorado, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, Nevada, Ohio, Texas.Flora L.

Institutional Ethnography and Experience as Data

Experience, as concept, is contested among feminists as to its epistemological status, thus its usefulness in knowledge claims. Institutional ethnography (Smith 1987) is a feminist methodology that nonetheless relies fundamentally on people's experience. Not as Truth, nor the object of inquiry, but as thepoint d'appui for sociological inquiry. This article offers a demonstration of institutional enthnography using observational and interview data that show experience as methodologically central to a trustworthy analysis. A moment in the work lives of nursing assistants in a long-term care setting is captured by a participant observer. The analysis produces two lines of argument. One is methodological; it is argued that nursing assistants' experiences are an entry into the social relations of the setting that, when mapped and disclosed, make those experiences understandable in terms of the ruling arrangements permeating both the organization and their own experiences. The other argument is substantive; the inquiry uncovers how a quality improvement' strategy in a long term care hospital in Canada is reorganizing caregivers' values and practices toward a market orientation in which care appears to be compromised. Use of experience as data in this approach holds the analysis accountable to everyday/everynight actualities in a lived world.     

消费者品牌信任机制建立及影响因素的实证研究

诚信危机是现代企业面临的严峻问题,而营销领域关于消费者对品牌信任建立的理论与实证研究还很匮乏。笔者在访谈和文献基础上,将相关领域的机制性研究与前因性研究两种方法相结合,提出了消费者品牌信任建立的三种机制(经验机制、计算机制和转移机制),并探查出能够反映每种机制的五个变量(感知质量、顾客满意、感知风险、经济价值和品牌声誉)。通过在化妆品行业收集的数据,使用结构方程模型分析,结果表明,经验机制和计算机制对建立品牌信任起作用,其中经验机制的作用最大。     

Pipage Rounding: A New Method of Constructing Algorithms with Proven Performance Guarantee

The paper presents a general method of designing constant-factor approximation algorithms for some discrete optimization problems with assignment-type constraints. The core of the method is a simple deterministic procedure of rounding of linear relaxations (referred to as pipage rounding). With the help of the method we design approximation algorithms with better performance guarantees for some well-known problems including MAXIMUM COVERAGE, MAX CUT with given sizes of parts and some of their generalizations.     

顾客消费情感对顾客满意感的影响

作者在广州某高校内的餐厅进行了一次实证研究,探讨顾客感觉中的服务质量、顾客情感和顾客满意感之间的关系。数据分析结果表明,顾客感觉中的软质量直接影响顾客餐后的正面情感,而顾客餐后的正面情感直接影响顾客满意感;顾客对软、硬质量的期望与服务实绩之差对顾客餐后的正面情感、顾客满意感都有显著的直接影响,顾客对软质量的期望与服务实绩之差对顾客餐后的负面情感也有显著的直接影响。此外,顾客餐前的情绪也会影响顾客餐后的情感和顾客对自己就餐经历的评估。     

顾客关系、信任与顾客对服务失败的反应

优异的服务质量是建立长期顾客关系的重要手段。本文通过实际调查,分析了服务质量的两个维度--结果质量和过程质量对顾客满意度和重购意愿的影响,并探讨了顾客关系和信任感在服务评价和顾客反应方面的作用。研究发现,服务过程和服务结果间存在交互作用,顾客关系对服务质量的影响发挥着调节功能,信任感经由服务结果而影响顾客的反应。
