A mixed spectrum management framework for the future wireless service based on techno-economic analysis: The Korean spectrum policy study

The evolution of radio technology and various services has increased the world's dependence on wireless communications. The demand for and value of spectrum resources therefore are also increasing. Spectrum efficiency is the most important factor in managing spectrum scarcity. However, under the current spectrum management approach, it is difficult to adopt innovative technologies that improve spectrum efficiency and flexible usage in the current dynamic wireless market. Recently, there have been several approaches to improve efficient use of spectrum resources, and each approach has its own advantages and disadvantages. Therefore, this research first discusses current issues and analyzes relative social welfare based on the different characteristics of technology and market conditions to compare various attributes of each approach. Based on the techno-economic simulation results, this paper introduces a mixed spectrum management framework for the future wireless service and support policy makers’ decision making. Furthermore, the mixed spectrum policy to spectrum management in Korea is proposed to find a more realistic and efficient spectrum management policy.     

全球价值链的“空间逻辑”及其区域政策含义——基于制造组装环节与品牌营销环节空间分离的视角

本文运用一般均衡及超边际分析方法,通过建立一个包含制造组装环节和品牌营销环节的内生分工模型来探索全球价值链的"空间逻辑"。研究表明:促进制造组装环节与品牌营销环节空间分离的主要动力有两个:一是发挥各个区域的外生比较优势,最大限度地提高整条价值链的生产效率;二是充分利用各个区域的专业化经济,尽量降低整条价值链的固定学习成本。而要实现制造组装环节和品牌营销环节的空间分离,需要制造产品以及品牌服务的区域间交易效率提高到一定的临界值,其中,品牌服务在提高市场交易效率方面的"正反馈效应"对上述两个环节空间分离的实现起着促进作用。在此基础上,本文进一步分析了模型衍生的一系列区域经济政策含义。

Roles for managing in mobile service development nets

This paper examines the roles for managing in business nets. The roles are studied by applying an initial conceptual framework built on network management research and role theory. The study empirically grounds the framework by using the case of a new mobile service development net. The article answers the question of what are the managerial action-based roles for managing in business nets. The empirical data of the study consists of fifteen interviews and a seven-month participant observation in a net that created and piloted a new mobile service directed at the spectators of a sports team. As a result of this study, an empirically grounded typology of twelve roles for managing in nets is presented. The roles are related to the changes in the net, the service development over time, and to the interpretations of the behaviours by the other actors in the net. Moreover, the study shows how external actors to the net can influence it.     

Managing international supply: The balance between total costs and customer service

Many trading companies have taken a global approach to their supply markets, sourcing from low-cost foreign countries in order to achieve cost reductions. There remains, however, a lack of evidence that sourcing internationally actually leads to improved economic performance. This can be explained by two key challenges in terms of how to achieve a balance between: (1) purchasing and logistics costs, and (2) customer service. The purpose of this paper is to examine the organisation and management of international supply from a total cost perspective, taking into account both purchasing and logistics costs, as well as customer service and agility. Previous research into a number of Norwegian companies that have sourced from China has identified four configurations for managing international supply. This paper utilises the supply management literature and an example of a Norwegian retail and wholesale company to analyse and discuss these configurations and their effects on total costs and customer service. The paper's theoretical contribution is the conceptualisation of a total cost perspective on international supply management and the discussion of such costs in relation to customer service. This contribution may, in turn, aid companies that source from foreign, low-cost countries.     

The Nature and Causes of Effective Human Resource Management

Abstract : Four models of the causes of effective human resource management were tested using a large sample of national health service (NHS) provider trusts and districts. The four models, labelled organizational integration, policy integration, functional integration and process integration, were operationalized and tested in a regression analysis against a range of qualitative and quantitative measures of HRM effectiveness. The results reveal little or no association between the qualitative and quantitative measures of effectiveness and show that the models are better at explaining qualitative effectiveness. The most strongly supported models are organizational integration, reflected particularly in the formalization by senior management of HRM policy, and process integration, reflected in the quality and efficiency of personnel service and support. There is little support for policy integration — the idea of a coherent policy focus — and none at all for functional integration, that is, the view that a personnel department generously staffed by professional specialists will enhance effectiveness. The theoretical and policy implications of these results are discussed.
