Driving forces in researchers mobility

Starting from the dataset of the publication corpus of the APS during the period 1955-2009, we reconstruct the individual researchers trajectories, namely the list of the consecutive affiliations for each scholar. Crossing this information with different geographic datasets we embed these trajectories in a spatial framework. Using methods from network theory and complex systems analysis we characterise these patterns in terms of topological network properties and we analyse the dependence of an academic path across different dimensions: the distance between two subsequent positions, the relative importance of the institutions (in terms of number of publications) and some socio-cultural traits. We show that distance is not always a good predictor for the next affiliation while other factors like "the previous steps" of the career of the researchers (in particular the first position) or the linguistic and historical similarity between two countries can have an important impact. Finally we show that the dataset exhibit a memory effect, hence the fate of a career strongly depends from the first two affiliations

Actor-relational planning in deprived areas : challenges and opportunities in luchtbal Antwerpen, Belgium

In this article we report and discuss our experience with actor relational approaches in the regeneration of a post war housing estate in Luchtbal, Antwerp, Belgium. Actor relational approaches are informed by post-structuralist ideas of space, complexity theory and actor network theory. Although ARA itself is not new, the application of ARA to deprived area’s such as Luchtbal is novel. We report how the approach has been elaborated, its process and outcome. We conclude with our evaluation from an insider’s perspective

Eurocities and Their "Sisters": How Are They Close to Each Other?

The globalization process has led to the emergence of network of cities in which the cities have become more integrated to the new world system. ‘Eurocities’ or ‘Sister Cities’ are among the well known examples of network of cities which provide interaction and cooperation of the cities at the regional and global level. The ‘sister city movement’ can be defined as a further step of international relationships of the cities at the municipality level which is based on understanding the cultures of each other and aims to create common values. Additionally, sister city relationship provides international trade and economic development between two countries at the local level. Empirical findings show that there are 3 phases of sister city movement: i) the associative phase, ii) the reciprocative phase, and iii) the commercial phase. In this process, municipalities or local authorities have become ‘entrepreneurs’ in order to contribute to the economic and social dynamisms of cities. The present study investigates the relationships of Eurocities with their sister cities from the perspective of the development level or the degree of the relationship. Which factors are important in improving the mutual relationship? Which factors determine the development phases of the relationship? Under which conditions the mutual relationship creates business opportunities and reaches to the level of economic cooperation? What are the success measures of city-to-city affiliation? The study aims to compare and evaluate the current sister cities relationships of Eurocities on the basis of the actual performance in cultural dialogue, benchmarking and commercial activities. The data and information used for comparison and evaluation are based on extensive survey questionnaires filled out by relevant departments or experts of municipalities in Eurocities. As a rather novel methodological contribution, a recently developed artificial intelligence method, i.e. rough set analysis, is deployed to assess and identify the most important factors that are responsible for successes and failures of the relationships between sister cities.

Mapping London's Innovation Networks

A wide range of authors have highlighted the potential benefits for entrepreneurial companies that engage in effective networking along and across the supply-chain. As many organisations have downsized or outsourcedbasic research activities Universities have an increasingly important role within such networks. A number of UK initiatives have been established to encourage greater 'entanglement' between academia and commerce; the London Technology Network is one example which is intended to encourage interactions between London's leading research institutes and innovative businesses.Using the detailed data acquired by this network this paper is intended to presents an exploratory analysis of such activities with the aim of establishing the extent to which company size, sector and/or location play a significant role in participation in the network's activities.

Networks in Berlin’s Music Industry – A Spatial Analysis

In addition to a distinct regional concentration of the branch in a few, large metropolitan areas in Germany, Berlin shows inner-city (inner-regional) concentrations of the music industry and its players linked with the value chain as well as branch-relevant institutions. By means of a written survey of companies in the media and IT industries in Berlin and Brandenburg plus expert interviews, an analysis of the Berlin music branch, regarding its spatial as well as organizational concentration and how this concentration is perceived by companies, has been carried out. A comparison of the results within the branch and with the Brandenburg region can be made on the basis of a differentiation of the media branch in the analysis. This analysis found that creative milieus are of particular importance as they perform the role of being the driving force in developing the field of music. Therefore this paper examines spillovers into this industry, as a first step of spatial concentration in terms of networks of music companies, institutions, and the specific and innovative milieu and the geographical dimension of knowledge. Furthermore, evidence has been found through the use of economic and socio-cultural indicators. Urbanization economies become especially clear (apparent) for the region in the examination of Berlin’s music industry with their intersectoral integration and cross-sectoral stimilus to settlement and formation of companies.

Management in the Gulf and Caribbean: mosaic or melting pot?

Does \u27\u27managing large pelagic fishes mean the same thing across the diversity of maritime jurisdictions, governance arrangements, economies, languages, cultures, scales of operation and other features of the Gulf and Caribbean region? It would be surprising if it did. Yet international fisheries management urges this mosaic of management to become a melting pot; at least integrated, even if differentiated. This paper examines some themes underlying whether a mosaic or melting pot is the most apt metaphor for where we are, and are headed, in attempts to manage large pelagic fishes in the region. We pay particular attention to the multi-dimensional concept of scale. Included are the scales of management units, fisheries authorities, management outcomes, harvest and postharvest enterprises, and the interdisciplinary perspectives that can be brought to bear on fishery problems and solutions. We are also interested in linkages, because linkage is connected to the scaling-up that is important in a region with many small countries and territories. Even if the management of large pelagics starts as a mosaic, coherent patterns of sub-regional and regional interactions can conceivably be nested and linked to improve the integration, and hence effectiveness, of management interventions ... at least in theory

Lifestyles, choice of housing location and daily mobility. Conceptual framework, methods and preliminary results of the interdisciplinary research project "StadtLeben"

Today, spatial research and planning is confronted with complex frame conditions which have substantially changed in the past decades. Thus, a comprehensive social change is stated, giving new room for individual development, but on the other hand making new decisions necessary (cue: individualisation). At the same time, settlement structures and time-regimes - essential conditions for spatial mobility - have developed dynamically (cues: decentralisation, flexibilisation). These trends are spatially resulting: - in a growing demand for housing size, which is realised predominantly in suburban and post-suburban settlement forms, - in high volumes of traffic in leisure, holidays, supply and commuting which are realised primarily by car and - in leisure and holidays - also by plane, - in changing mobility rationales; for instance, migrations are increasingly substituted by high distance commuting, - in new, partially virtual mobility forms (internet surfing, e-commerce, online banking, 'virtual leisure', event leisure). These mobility forms are characterised by interdependencies with physical passenger travel and freight transport as well as locational choice. From the perspective of a sustainable urban development, these trends have to be partially assessed as incompatible. At the same time, they offer chances for a more sustainable configuration of locations and transport. For instance, the change from industrial to service society facilitates the renaissance of the spatial integration of housing and working. New information and communication technologies allow to reduce job and supply trips (tele working, e-commerce). However, hitherto research and planning show serious methodological problems in the consideration of the stated changes. The explanation patterns of existing approaches for spatial mobility are mainly based upon spatial and individual restrictions. Neither the increasing degrees of freedom nor the subjective rationales behind mobility decisions are adequately considered. The referee presents the conceptual framework, methods and preliminary results of the interdisciplinary research project "StadtLeben". In this project, transport researchers, urban planners, geographers and psychologists from the universities of Aachen, Dortmund, Berlin (FU) and Bochum are working together. The project is supported by the German Federal Ministry of Education and Research in the research programme "Building and Housing". The central research question focuses on the interrelation between social structures (lifestyles, milieus), space-time-structures, housing resp. choice of housing location, and everyday mobility. In exemplary study areas in the urban regions of Köln and Leipzig, the specific interdependency of lifestyles, milieus and space-time-structures (f.i. infrastructure facilities, characteristic urban structures) as central influences on spatial action is investigated. In doing so, it is assumed that these interdependencies are to be understood as "contextual figures" rather than as clearly defined one-directional causal chains. The proposed research approach shall help to investigate the complex and manifold interrelations between social and spatial structures as well as the choice of housing location and everyday mobility. By means of this advanced descriptive and explanatory approach, target group-oriented and efficient planning and design strategies shall be developed. Together with planning practitioners, action-oriented knowledge as well as suggestions for planning methods (participation, processes, competence) shall be derived.
