基于两层架构协调的应急物资分配与车辆调度集成优化方法

针对突发事件下的应急物资调运问题，考虑了多个地区同时受灾以及多个出救点需要对其进行救灾并且各出救点的运力有限的情况，以最小化总的车辆运输费用，最大化救灾效率、各受灾点的救灾满意度，以及各受灾点得到救助的公平性为目标，建立了该问题的多目标混合整数非线性规划模型，并提出了一个基于两层架构协调的迭代式遗传算法进行求解。基于仿真数据的实验结果证明了所提出的模型和算法的有效性。     

Activation and variation of the United Nation’s cluster coordination model: a comparative analysis of the Haiti and Japan disasters

The coordinated response to extreme events is critical as illustrated by recent disasters in Haiti and Japan. As a way for coordinated provision of international humanitarian assistance to disaster-hit countries, the Office for the Coordination of Humanitarian Affairs (OCHA) developed cluster coordination model (CCM). With content analysis and network analysis of OCHA situation reports, this study checked four premises regarding activation of CCM, interaction between national and international actors, roles of proximity country, and level of cluster coordination. This study found that there were meaningful variations in implementing the CCM for 2010 Haiti and 2011 Japan disasters. From the analyses, we found that the current CCM may be vulnerable to black swan disasters; thus, extensive and active estimation of national disaster management capacities should be conducted to prevent collapse of national disaster management system. However, the reconciliation of state sovereignty and international humanitarian assistance also should be considered.     

博罗县耕地变化及其影响因素分析

[目的]试图探讨广东省博罗县耕地时空动态变化与社会经济发展之间的关联度,分析其社会经济发展与当地耕地时空动态变化之间的相关性特点。[方法]基于2005~2014年广东省博罗县耕地资源数据及其相关社会经济资料选取19个指标建立评价指标体系,借助SPSS软件找出社会经济变化的主要驱动因子,并借助DPS软件进行灰色关联分析,得到该地区社会经济发展与耕地面积变化之间的相关性关系,从而量化不同因素对于耕地数量变化的影响程度。[结果]影响耕地变化最大的经济因素为地方财政收入,其关联度高达0.994;城市化水平与耕地面积之间相关性很高,其关联度为0.991;地区生产总值(GDP)与耕地数量变化之间相关性较高,其关联度为0.830。[结论]2005~2014年博罗县耕地数量波动相对较大总体呈现略微增加趋势,人均耕地呈现下降趋势,且经济发展与耕地数量变化关系较密切。

京津冀城市群耦合协调发展及时空演化研究

本文通过构建城市系统指标体系，运用熵权赋值法和耦合协调度模型，测度和分析了2005~2015 年京津冀城市群经济--科技--人口--土地的综合发展水平、协调关系及演化特征。研究表明，从时序看，京津冀城市群经济、科技、人口与土地基本处于低级耦合协调状态，人口发展和土地扩张仍是经济发展的主导模式，而科技系统发展持续低迷，创新驱动格局尚未形成。从空间看，京津冀各城市耦合协调水平整体提升，逐渐形成以北京、天津为中心，沿京津发展轴、京保石发展轴蔓延的协调发展格局，而城市各系统协调发展呈现空间分异特征，“协调高地”与“协调失灵”局面并存。因此，应大力实施创新驱动战略，加快形成人口多中心分布格局，强化土地利用协调管理，促进区域经济、科技、人口、土地协调发展。     

A LITERATURE SURVEY ON PROPOSED AFRICAN MONETARY UNIONS

This study provides a survey of recent advances in the literature on proposed African monetary unions. The survey comprises about 70 empirical papers published during the past 15 years. Four main strands are discussed individually and collectively. They comprise the proposed: (i) West African Monetary Zone (WAMZ), (ii) East African Monetary Union (EAMU), (iii) Southern African Monetary Union (SAMU) and (iv) African Monetary Union (AMU). We observe a number of issues with establishing the feasibility and/or desirability of potential monetary unions, inter alia, they are variations in: choice of variables, empirical strategies, sampled countries and considered periodicities. We address this ambiguity by reviewing studies with scenarios that are consistent with Hegelian dialectics and establish selective expansion as the predominant mode of monetary integration. Some proponents make cases for strong pegs and institutions as viable alternatives to currency unions. Using cluster analysis, disaggregating panels into sub-samples and distinguishing shocks from responses in the examination of business cycle synchronisation provide more subtle policy implications. We caution that for inquiries using the same theoretical underpinnings, variables and methods just by modifying the scope/context and periodicity may only contribute to increasing the number of conflicting findings. Authors should place more emphasis on new perspectives and approaches based on caveats of, and lessons from the European Monetary Union (EMU) and CFA zones.     

基于信息系统体系下的军人健康度评估问题研究

辽宁棕壤耕地质量评价及障碍因素类型分区研究

[目的]以土壤类型为基础,选取土壤管理、理化性质、土壤养分、剖面性状、立地条件和气候条件等6个方面14个指标对辽宁棕壤耕地质量进行综合评价,在分析主要障碍因素基础上,根据障碍因素组合类型的不同对辽宁棕壤耕地进行质量障碍因素类型分区。[方法]采用模糊数学法和层次分析法,利用障碍度模型对辽宁棕壤耕地质量障碍因素进行诊断,分析棕壤耕地质量障碍因素类型分区。[结果](1)辽宁棕壤耕地高等地、中等地和低等地,分别占棕壤耕地总面积的21.49%、59.18%和19.33%,耕地质量等级以中等地为主;(2)障碍因素组合类型共14种,根据障碍因素不同划分为3个耕地质量障碍因素类型区,即有机质障碍类型区、灌溉能力障碍类型区、质地障碍类型区,分别占棕壤耕地总面积的86.45%、10.75%和2.80%。[结论](1)针对障碍因素类型分区,提出各区以障碍因素为主的耕地质量保护与提升措施,从而保证粮食生产;(2)文章从耕地土壤类型角度研究耕地质量障碍因素类型分区及其利用策略,为耕地质量保护与提升研究提供新视角,为耕地资源分区利用与管护研究提供参考依据。     

Service innovativeness and the structuring of organizations: The moderating roles of learning orientation and inter-functional coordination

This paper aims to investigate the influence of organizational structure on service innovativeness by testing the moderating roles of learning orientation and inter-functional coordination. This helps to understand how organic structure influences service innovativeness when it is effectively leveraged with favorable organizational factors. Data were collected from 178 hotel managers and executives in Japan and moderated regression analysis was performed to analyze the data. Findings of the study suggest that higher levels of service innovativeness are positively related to higher levels of hotel business performance. In addition, organic structure makes a positive influence on service innovativeness and an increase in the levels of learning orientation boost the effectiveness of organic structure on service innovativeness. Moreover, the positive association between organic structure and service innovativeness become stronger when all firm’s functions make an attempt to cooperate and contribute to disseminating customers and competitors’ information in the hotels. These findings contribute to understanding how hotel service innovation is affected by service innovativeness, organizational structure, learning orientation and inter-functional coordination.     

市外旅行商行为与重庆旅游地营销匹配度探讨——基于网络调查视角

旅行商是连接旅游者和旅游地的桥梁。虽然旅行商与旅游地之间形成密不可分的利益关系,但在现实的旅行商和旅游地关系中,却存在较多的问题:个别大型旅行商"绑架"要挟旅游地,旅游地营销战略与旅行商推荐线路性质不匹配等。以压力-状态-响应理论和刺激-反映理论为指导,选取2010年和2011年国家旅游局发布的100强上榜旅行商中的重庆旅游地以外的60家旅行商为样本,通过网络调查方法,获取其推介的重庆旅游线路的相关情况,并加以分析整理,再结合重庆市旅游营销的具体实践,探求二者之间的匹配响应关系,得出市外旅行商和重庆旅游地营销之间存在匹配响应较低的结论,其结果是大大降低重庆旅游营销效果。最后,文章给出旅游地和旅行商之间匹配关系调整的一些对策,以期对重庆旅游营销有所裨益。
