Inconvenience cost of mobile communication failure: The case of South Korea

Mobile communication failure can occur when mobile traffic exceeds the manageable level. This depends on frequency bandwidth. Mobile communication failure causes inconveniences in a user's daily life that lead to social and economic damage. To address this issue, mobile telecommunications companies deploy additional bandwidths and develop new technologies, but these are costly strategies. This study applies a spike model based on a contingent valuation method (CVM) to measure the inconvenience cost resulting from mobile communication failure. The mean monthly willingness-to-pay (WTP) to avoid communication failure per user is estimated to be KRW 898.14 (USD 0.80) over a period of five years in our study. The inconvenience cost borne by the population is estimated to be KRW 2.97 trillion (USD 2.61 billion). Users experiencing greater frequency of communication failure are found to be willing to pay more to avoid the inconvenience. When excluding respondents citing zero-WTP, the mean WTP per user was calculated to be KRW 3426.41 (USD 3.01). Data traffic usage and frequency at which communication failure is experienced are variables that exhibit statistically significant effects on WTP to avoid mobile communication failure. Overall, estimation results show that a price discrimination based on data traffic usage or quality can be considered by mobile telecommunications companies and regulators to address the issue of data traffic inducing mobile communication failure.     

The views of key stakeholders on an evolving food risk governance framework: Results from a Delphi study

Evidence of a decline in public trust associated with food risk governance over recent years has called into question the appropriateness of the current dominant risk analysis framework. Within the EU-funded SAFE FOODS project a novel risk analysis framework has been developed that attempts to address potential shortcomings by increasing stakeholder (including consumer) input, improving transparency, and formally incorporating benefit and non-health aspects into the analysis. To assess the viability of this novel framework, the views of food risk experts from the EU and beyond were sought using a distributed online questionnaire process called Delphi. In this paper the main results of this survey are described, revealing varying levels of support for the key innovations of the novel framework. Implications of our results for the new and old frameworks, for the future of risk analysis, and for the policy community more widely, are discussed.     

基于无线局域网标准的天然气长输管道通信系统的整合

通信系统在天然气长输管道的生产运营中起着至关重要的作用。目前陕西省天然气股份有限公司通信网由公司总部、西安、延安、杨凌分公司及22个输气场站等多个不同的独立建设的系统构成,各自独立建网形成了一个个“信息孤岛”。采用基于无线局域网标准的VOIP系统整合陕西省天然气股份有限公司通信网,一方面可使闲置的带宽得到充分利用．另一方面也能有效降低系统内部通信费用,有效消除通信障碍,提高工作效率和企业管理水平。     

银行跨国并购中的文化差异识别体系研究

在跨国并购中,并购银行将面临民族文化和企业文化双重差异和冲突带来的挑战,而且缺乏对文化差异的理解和管理是并购失败的首要原因。在并购实施中,我们有必要把文化整合与业务技术整合看成截然不同但又紧密相关的两个领域,而构建文化差异识别体系是文化整合的基础。本文从感知跨国并购中的文化差异冲突和融合入手,提出构建文化差异识别体系应以整合战略执行为导向,突出促成行为改变的关键要素;提出了涵盖人本文化、处事文化、沟通文化等角度,共7个维度、22种偏好的文化差异识别体系的基础框架。     

团队氛围、董事会内部沟通与战略绩效

本文在理论分析的基础上提出研究假设,通过问卷调查的方式搜集数据,以47家企业董事会454份有效问卷为样本进行实证研究,结果表明,团队氛围中的团队信任对董事会内部沟通具有显著的正向影响;团队氛围中的情感冲突对董事会内部沟通具有显著的负向影响;董事会内部沟通对企业战略绩效中的团队学习力、决策有效性和战略一致性均具有显著的正向影响。研究不仅丰富了董事会团队过程理论,而且能够有效地指导公司治理实践。     

人类形成合作关系的条件

大群体中的合作关系必须以利己主导型经济人为出发点来加以说明。大群体中出现合作的首要条件是净交往惠利大于零;第二个条件是信息和知识完全,即各方要有共同知识;第三个条件是存在着抑制人们背离合作的机会主义行为倾向的各种机制。

案例教学知识转移机理研究

随着管理学科的不断发展,管理知识的情境性与实践性日益突显,对管理学科的教学提出了更高的要求。作为一种基于案例创设情境,鼓励学生主动实践、互动讨论的教学方法,案例教学法逐渐成为管理学科教学中不可或缺的方法。本文以高校管理学科案例教学为研究对象,通过结构方程模型的实证研究方法探究了案例教学特征通过影响学习者行为从而促进管理知识转移效果的作用机理。实证研究结果表明,案例教学的情境模拟性特征既能够直接促进管理知识的转移,同时也能通过提升学习意愿间接提升管理知识的学习效果,而师生平等性特征则通过影响学〉-7意愿影响管理知识的转移效果,为高校管理学科案例教学的有效开展提供了新的理论依据。     

Communicating culture change

Using a case study of a large public sector department the relationship between communication and change in a public sector department and the human resource implications of that relationship are considered. Senior administrators of the department signified their intention to change the culture from one that was considered to be bureaucratic, technically oriented and inward-looking to one more outward-looking, continually learning, more relationship-oriented internally and inclusive of broader ‘whole of government’ objectives such as commercialization, the environment, social justice and community relations. Findings from the research indicate that, despite an objective of shifting to a state of continual change with the mode of communication becoming two-way and dialogic, the communication mechanism has faltered due to a failure to address the need of lower-level staff for a set vision and stated future direction. Implications of these findings are drawn for public sector organizations in general.
