元明清政府决策与淮河问题的产生

元明清时期,京杭大运河的开通,便利了北方政治中心与南方经济中心之间的联系。特别是在明清时期,大运河漕运事关国计。当时政府的诸多治河措施是为确保漕运畅通,加之明代保陵的需要,更使黄河、淮河、运河之间的关系复杂化。封建政府的决策行为使本自独流入海的淮河改道主要由长江入海,使淮河流域成为十年九灾之区。     

Seeing Past Parallel Play: Survey Measures of Collaboration in Disaster Situations

The literature on the management of policy networks has expanded greatly in the past decade. In spite of this attention, no consensus has emerged on how to measure collaboration or even what constitutes collaboration. This article uses data from a postdisaster survey to compare some existing approaches to measuring collaboration. We analyze various survey‐based measures ranging from respondent‐defined collaboration to activity‐based or contact‐based measures. We recommend that scholars consider opportunity costs as a key component in differentiating between significant collaboration and basic coordination (or “parallel play”). Based on this opportunity cost approach, we consider the distinctiveness of disaster collaboration.     

Baseline Models for Two‐Mode Social Network Data

Baseline models have been used in the analysis of social networks as a way to understand how empirical networks differ from “random” ones. For the purposes of social network analysis, a “random” network is one chosen—at random—from a population of possible graphs derived from a given generating function. Although these principled hypothesis tests have a long history, many of their properties and extensions to multiple data structures—here, specifically two‐mode data—have been overlooked. This article focused on applications of different baseline models to two data sets: donations and voting of the 111th U.S. Congress, and organizations involved in forums on watershed policy in San Francisco, USA. Tests using each data set, but with different baseline reference distributions, will illustrate the range of possible questions baseline models can address and the differences between them. The ability to apply different models and generate a constellation of results provides a deeper understanding of the structure of the system.     

Travel,migration, exile: Garibaldi's global fame

In this article, it is argued that Garibaldi's global fame owes much to his own experiences as a migrant and exile in the Americas. Overseas, Garibaldi not only acquired several practical and political skills, he also built up an important network of friends and supporters and became a hybrid figure able to adapt his image to diverse political settings. At the same time, Garibaldi relied on the trope of exile, developed by people like Ugo Foscolo, to define his opposition to, first, Italy's Restoration governments and, after Italian unification, the new moderate liberal regime. The article also looks at Garibaldi's life on Caprera and it is further argued that here Garibaldi combined elements of his previous experiences to fashion a role for himself as a ‘foreigner in Italy’. Garibaldi was a symbol of many worlds as well as a hero of two and it is precisely this hybrid nature of his appeal that can explain his global popularity.     

中国食品出口贸易地理网络演化

华人网络与文化距离对中国食品行业贸易地理网络的形成与演化具有显著影响.本文基于2000-2016年中国海关贸易数据库,首先展示中国各省份食品贸易地理网络格局及其演化趋势,研究发现我国东部省份以东亚和北美为主要出口目的地,中西部省份贸易网络的空间不均衡性较强,且各省份食品出口均有贸易联系强化和目的国多样化特征.其次,构建...     

农区产业集群、网络与中部崛起

我国中部六省地区由于多种原因在全国区域经济格局中已经成为了"经济增长速度的相对塌陷地区",实施"中部崛起"战略是学术界、中央和地方政府达成的共识。本文在分析中部地区存在问题的基础上提出,实施产业集群战略、创建本地企业网络是实现中部崛起的有效途径。发展农区产业集群可以提高集群企业和区域产业的竞争力,推动农村工业化和城镇化进程,促进县域经济的发展。而企业之间的网络联系是产业集群的本质特征,培育产业集群必须从创建企业网络入手。最后,本文对如何在中部农区培育产业集群、创建企业网络作了探讨。     

RESISTANCE AND STRATEGIC RESPONSES IN FOOD SUPPLY NETWORKS: METRO CASH & CARRY IN BANGALORE

The transnational expansion of large retail and wholesale companies such as Metro, Carrefour and Wal‐Mart has caused changes in the market situation and consequent power shifts, not only in the retail sector but also in the supply networks in host countries. These developments at least potentially endanger the livelihoods of old established retailers, intermediaries and employees of these businesses. Thus, it is not surprising that the investments of the transnational companies can result in resistance from those affected. As an analysis of Metro and its activities in the federal state of Karnataka in India shows, this resistance can influence the activities of the company to develop a modern supply network. This study analyses the way in which the actors of resistance develop and exercise power and how this in turn influences Metro. The global production network (GPN) approach is used as an analytical framework. The results emphasize the importance of networks external to the firm for the analysis of processes of globalization. The company's behaviour cannot be understood unless the resistance is taken into account. The study shows that the GPN framework provides the tools to analyse the influence of actors such as civil society groups, trade unions and associations as part of the production network. However, up to now this option has rarely been used.     

UNIQUE ISOLATION VERSUS NETWORKS OF OPPORTUNITY: THE COMPETING DISCOURSES OF TASMANIA

In order to understand why people move, we must first try to comprehend how they understand their migration decisions and recognize that such understandings are intricately tied to their understandings of places. Place construction – the way people understand and discuss the nature and meaning of places – occurs at all levels from individual constructions to constructions by economic and political interest groups. These place constructions necessarily influence each other, and hence they are in constant flux and reflect power relations evident in society. This article examines these issues in the context of the negative net migration of young adults in the Australian state of Tasmania through an examination of the experiences of thirty young return migrants who participated in in‐depth interviews and group discussions about their experiences of migration. It finds that bounded constructions of Tasmania – which stress the physical isolation and social and political insularity of the state as well as the uniqueness of the state's environment and society – appear to be dominant for these young returned migrants. However, the article argues that these bounded constructions necessarily exist in relation to networked constructions, which focus on the opportunities for people, ideas, goods and money to benefit through connections with other places as well as the loss of the uniqueness of the Tasmanian environment and society. This article concludes with a discussion of the political, economic and social consequences of these different forms of place construction.     

The contribution of Sir Alan Wilson to spatial interaction and transport modelling

ABSTRACT

In a series of papers in the mid-1960s and early 70s, building on his key 1967 paper, Alan Wilson made a series of fundamental contributions to the specification and application of land-use transport models. In this paper the basis of his entropy-maximizing approach to spatial distribution models is outlined with a demonstration that the methods have applications very much beyond its transport roots. The entropy maximization method laid the foundations for the development of a range of multinomial logit share models. He expanded the core transport ideas to the whole range of comprehensive models, initially building on, and extending, Lowry's iconic Pittsburgh model. The factors that have sustained the longevity of Wilson's models are explored and articulated.     

Global TransPark: New Competitiveness for Hong Kong and South China Based on Air Logistics

Economic globalization in the past two decades has led to a fast pace of growth of many economies in Asia Pacific, and impacted on the region's growth in air cargo. This paper discusses the future of airport infrastructure and its effect on regional competitiveness in the form of a new type of airport — Global TransPark (GTP). It identifies China's need to forge such a critical infrastructure in the New Economy, and that South China is its best location. The Hong Kong Extended Metropolitan Region (EMR) in South China stands out among competitive regions in Asia in terms of geopolitical and institutional setting under ‘One Country, Two Systems’ as the best general location for Asia's first and potentially largest GTP. Forging a GTP will promote the EMR's overall competitiveness and hastens its economic restructuring. The paper then discusses the advantages of Zhuhai Airport as the site of the potential GTP which will also incorporate the other four nearby airports within the EMR. The GTP is also a new challenge for intra-EMR cooperation in terms of customs and tariff, air rights, ground handling, and land and water transport coordination between its airports and respective local governments.
