考虑干扰风险影响下应急物流仓储量最优模型分析

传统模型在处理应急物流仓储量时,存在抗风险弱、误差大的缺陷,容易出现混乱,无法进行有效的调度,不能满足及时的应急物流需求。为了解决这一问题,提出一种考虑干扰风险影响下的应急物流仓储量最优模型,模型使用仓储量方案优化指标体系层次结构,分析不同的干扰风险因素,获取最佳的仓储量控制方案,通过立体物流仓储模型获取仓储货位的有效货物量,采用微粒子优化算法对立体物流仓储模型进行优化求解,获取最佳的仓储量。仿真实验结果表明,该模型能够准确描述不同的干扰风险,具有较高的仓储量优化效率和较低的误差率。     

Internal branding experiences in the financial services sector in South Africa

There is little doubt that employees are critical to the delivery of the service brand. Although existing models propose methods of internal branding, very little is known about the actual corporate experience. Academics around the world have spent decades probing internal marketing, its subset—internal branding—and the impact of internal branding on service delivery. This research focuses on how organisations execute internal branding, revealing critical success factors as well as obstacles encountered. The research was conducted in five large organisations in the financial services sector in South Africa. Each organisation is a highly recognisable consumer brand; the oldest of which is nearing 200 years of being in business and the youngest is just 20 years old. This research adds to the body of knowledge regarding organisational practice of internal branding. Key themes are identified, three of which are largely absent from extant models and literature.     

Does Religion Mitigate Tunneling? Evidence from Chinese Buddhism

In the Chinese stock market, controlling shareholders often use inter-corporate loans to expropriate a great amount of cash from listed firms, through a process called “tunneling.” Using a sample of 10,170 firm-year observations from the Chinese stock market for the period of 2001–2010, I examine whether and how Buddhism, China’s most influential religion, can mitigate tunneling. In particular, using firm-level Buddhism data, measured as the number of Buddhist monasteries within a certain radius around Chinese listed firms’ registered addresses, this study provides strong evidence that Buddhism intensity is significantly negatively associated with tunneling. This finding is consistent with the view that Buddhism has important influence on corporate behavior and can serve as a set of social norms and/or an alternative mechanism to mitigate controlling shareholders’ unethical tunneling behavior. In addition, my findings also reveal that the negative association between Buddhism intensity and tunneling is attenuated for firms that have high analyst coverage. The results are robust to various measures of Buddhism intensity and a variety of sensitivity tests.     

苏北地区农业完全成本水价农户承受力调查——基于水源地生态补偿的视角

南水北调东线一期工程江苏段的主要目标是向苏北供水,缓解该地区的农业用水短缺问题。但现行农业水价未考虑水源区的机会成本损失,不利于调动水源区环境保护积极性。论文设计单边界CVM引导技术,估算了苏北农户以提高农业水价的方式对水源区生态补偿的支付意愿。研究发现,苏北农户生态补偿支付意愿为7.63元/亩,但在不同作物种植结构和不同城市存在较大异质性。未来3年内,苏北农业用水每年所提供的生态补偿资金总额在1.526~1.679亿元之间。在发达地区探索构建绿色导向的农业水价体系有利于为其他地区提供先行示范效应。     

When Research Meets Development: Antecedents and Implications of Transfer Speed

This paper focuses on the organization of new product development in large, R&D‐intensive firms. In these firms, research and development activities are often separated. Research is conducted in dedicated research projects at specialized research labs. Once research results are achieved by research projects, they are transferred to business units for further development and commercialization. We investigate the speed whereby research projects transfer their first research results to business units (hereafter: transfer speed). In particular, we analyze the antecedents and performance implications of transfer speed. Based on data of 503 research projects from a European R&D intensive manufacturing firm, our results suggest that a fast transfer speed (as measured by the time it takes for a research project to develop and transfer its first research result to business units) is associated with a better research performance (as measured by the total number of transfers the research project generates). Moreover, we find that different types of external R&D partners—science‐based and market‐based partners—play distinct roles in speeding up project first research transfers. While market‐based partnerships (i.e., customers and suppliers) generally contribute to a faster transfer of first research results, science‐based partnerships (i.e., universities and research institutions) only speed up first research transfers of technologically very complex projects. Our results also show that early patent filings by research projects accelerate first research transfers.     

转型期的中国城市贫困问题及治理

城市贫困问题是实现全面建成小康社会的重大障碍之一,认识城市贫困问题依赖于"贫困识别-机理-反贫困"的系统研究。我国城市贫困人口众多,贫困发生率敏感性高,呈现地域分布显著差异显著、结构复杂化和低龄化、贫富差距严重、空间聚居不断边缘化的特点。社会结构和个体行为两个方面的原因导致了城市贫困问题的产生,对城市的经济、社会、政治发展都产生了不利影响。尽管当前的反贫困政策取得了一定成效,但仍然存在不能满足贫困者最低层次的多种需求,忽视了对贫困群体能力开发的问题。新时期的城市贫困治理应当在完善社会保障体系、加强城市基础设施建设、开展职业教育培训、鼓励有能力的贫困群体积极参加工作等方面展开。     

Financial investor sentiment and the boom/bust in oil prices during 2003–2008

From both theoretical and policy perspectives, it is important to understand if financial speculation contributes to the boom/bust in oil prices during 2003–2008. In this paper, we disentangle the effects of financial speculation from those of economic fundamentals by focusing on exogenous changes of financial speculation in oil markets identified by changes in financial investor sentiment. Furthermore, we focus on a quasi-experiment setting, and investigate both sentiment-driven overvaluation of oil prices and subsequent mispricing correction. Our findings suggest that financial speculation might have contributed to the 2003–2008 boom/bust in oil prices.     

Factors influencing theme park visitor brand-switching behaviour as based on visitor perception

With the development of theme parks, which represent a multi-million-pound industry worldwide, research investigating the factors affecting theme park visitor brand-switching behaviour is an important method for improving theme park competitiveness. In the present work, models and research hypothesis are constructed based on visitor perception, and the survey data are collected and analysed to assess the hypothesis and to revise the conceptual model in this paper. The results indicate that there are seven factors influencing visitor brand-switching behaviour: ‘visitor variety-seeking', ‘visitor satisfaction', ‘switching cost', ‘perceived value', ‘competitor attraction', ‘theme park image' and ‘visitor involvement'. The perceived value and visitor satisfaction strongly influence brand-switching behaviour as intermediate variables. Visitor variety-seeking and competitor attraction are positively related to visitor brand switching behaviour, whereas the other five factors are negatively related to visitor brand-switching behaviour.     

旅行社供应链管理初探

在旅游业转型时期,旅行社为主体的供应链模式将发生变化。尤其在电子商务的冲击下,以旅行社为代表的旅游代理商面临着极大的挑战,以单个企业运作的旅游企业再也不能适应时代的要求,基于供应链管理的旅游业管理模式便应运而生。目前大多数旅行社在供应链管理中存在企业对建立旅行社供应链管理模式的重要性认识不足、供应链上各企业缺乏合作、没有形成整体合力、信息系统不完善、供应链上的各企业对市场环境变化不敏感等问题。应采取注重旅行社供应链管理模式下的合作伙伴关系、提高对建立旅行社供应链管理模式的重要性的认识、完善管理信息系统、加强供应链上各企业信息技术标准的规范化建设、旅行社的集团化发展、实行跨文化管理等措施来解决旅行社供应链管理中的瓶颈问题。
