US and East Asian Security under the Obama Presidency: A Japanese Perspective

The most important factor determining the structure of East Asia will continue to be the strategic relationship between the USA and China. It is the key component of the six party talks on the North Korean problem as well as nuclear nonproliferation. Japan is obviously a lesser strategic player, which is in a position to encourage middle-power security cooperation among the East Asian countries breathing between the USA and China. There is a conceptual, if not geopolitical, competition between Japan and China over an ideal future of East Asian regionalism, which the East Asian countries and the USA should join in a constructive manner.     

Decomposing Input–Output Tables to Establish the Effects of Temporal Changes in Demographic and Economic Characteristics

This paper reports on an analysis of economic and demographic changes in the UK during the period 1981–91, using an extended input–output (IO) formulation designed to measure impacts of such changes in economic and demographic systems. We derive a simple temporal change decomposition method and apply it to the extended IO formulation. This is then linked to a labour market account decomposition, and the conjoint decomposition applied to two labour market accounts and two IO tables for the UK. We are able to identify the impacts on the demographic and economic systems caused by changes in the economy, economic activity of the population, natural population change, migration and coefficient shifts of different types.     

How store attributes impact shoppers’ loyalty: do different national cultures follow the same loyalty building process?

This paper takes a first step toward verifying the robustness of a comprehensive loyalty building model across different national cultures, according to Hofstede’s distinction between individualist and collectivist countries. To this end, we test a two-stage model. After collecting data from 12 countries with different cultural traits, we test the two models in two macro groups: individualist and collectivist countries. The study’s results show that the intensity of some core loyalty model paths – particularly the relationships between store loyalty and its main drivers (perceived value and customer satisfaction) – are contingent on the country’s culture. In particular, the impact of customer satisfaction on store loyalty intention is greater in collectivist countries than in individualist countries. By contrast, the impact of perceived value on store loyalty is greater in individualist than in collectivist countries. Moreover, the cultural dimension moderates the impact of the stores’ environment and promotions on satisfaction. By contrast, some other paths show robustness to national culture.     

A hierarchical approach to modeling hurricane disaster relief goods distribution

The need to create effective plans for distributing aid after a hurricane is of increasing importance in the transport community, as recent research suggests stronger storms will be affecting more people located in highly populated areas. Studies show that not all people will choose to evacuate an at-risk region or seek protection at shelters. To this point there have been relatively few efforts exploring the use of geographic information systems in conjunction with spatial optimization models in post-hurricane settings to accomplish efficient placements of facilities for distributing relief services. Despite the fact that hurricane relief strategies could benefit from a standardized methodology that reliably provides efficient placements for relief facilities, no research has examined the possibility of implementing a hierarchical structure among these facilities. This paper suggests a type of hierarchical capacitated-median model for this purpose. Two variations of this model are tested and their solutions are compared to that of a non-hierarchical version of the capacitated-median model. Findings suggest that if there is limited availability of certain services it could be useful to employ the use of a hierarchical capacitated-median problem to help place distinct facilities that provide different levels of assistance.     

基于最小生成树理论的空间结构分解模型

现有空间结构分解模型存在测算结果不唯一及不满足传递性两大问题。本文提出了一种基于最小生成树理论的空间结构分解模型,在保证多个地区间比较传递性的同时,减小了结构分解模型测算结果不唯一性对模型应用的影响。基于我国地区投入产出表,本文以ICT产业区位商比较的五变量结构分解为例,示范了如何定义帕式—拉式偏离指数(PLS),建立了基于PLS指数的最小生成树,并将结论应用于空间结构分解,对该模型的有效性进行了验证。     

区域金融发展水平差异的测算与比较：以安徽省为例

本文从与区域金融发展相关的因素出发,对安徽省17个地区的金融发展因素进行了归纳分析,试图发现安徽省区域金融发展水平的差异与特点,并在此基础上,对安徽省区域金融发展提出了相关的政策建议。研究发现,与整体经济发展水平相似,安徽省区域金融发展水平同样呈现出南北不均衡的特点。     

企业区位选择与空间集聚的博弈分析

针对完全竞争市场条件下无法从企业的区位选择导出空间集聚的问题,本文对Hotelling模型进行了扩展,并运用博弈论的思想对企业的空间分布和集聚情况进行了分析.在Hotelling模型基础上,是否考虑集聚收益对企业空间分布产生重要影响:不存在集聚收益下的企业选择只取决于消费者偏好;但是考虑集聚收益后,企业的空间集聚不仅取决于消费者偏好,而且商品价格、运费率、集聚强度和消费者收入均会产生重要影响.     

Combining service frequency and vehicle routing for managing supplier shipments

This paper proposes a new approach to designing inbound material collection routes that considers pick-up frequency and spatial design as joint decisions to minimize total logistics (transportation plus inventory) cost. The clustering-based optimization uses an approximation to the actual cost of a routing solution without actual route construction. We show that the problem is analogous to a single-source fixed-charge facility location problem, and near-optimal solutions can be found using an efficient heuristic algorithm. Tests show the effectiveness of how this model is formulated and a case study demonstrates that substantial total cost savings can be achieved in realistic applications.
