Given the field's interdisciplinary nature, regional scientists come with a wide spectrum of backgrounds. In this paper, we study the contributions to regional science made by scholars from Japan. First, we briefly examine how Japanese regional scientists came to develop a keen sense towards urban problems. Second, we identify the most influential authors and papers via a citation analysis. The results indicate that scholarly outputs in regional science are reaching a wider audience beyond scientists, while maintaining the order of impact among them. Lastly, we focus on the new economic geography where Japanese scholars have made a significant contribution.  相似文献

ABSTRACT

There is ample evidence of regions diversifying in new occupations that are related to pre-existing activities in the region. However, it is still poorly understood through which mechanisms related diversification operates. To unpack relatedness, we distinguish between three mechanisms: complementarity (interdependent tasks), similarity (sharing similar skills) and local synergy (based on pure co-location). We propose a measure for each of these relatedness dimensions and assess their impact on the evolution of the occupational structure of 389 US Metropolitan Statistical Areas (MSA) for the period 2005–2016. Our findings show that new jobs appearing in MSA’s are related to existing ones, while those more likely to disappear are more unrelated to a city’s jobs’ portfolio. We found that all three relatedness dimensions matter, but local synergy shows the largest impact on entry and exit of jobs in US cities, thus being the strongest force of diversification.  相似文献

Since 2005, when Hurricane Katrina wreaked havoc on the Gulf Coast and New Orleans, our polarised perception of land and water has been irrevocably shifted by the failure of static levee flood-control systems. Ila Berman explains how a more fluid geographical approach to land and water, which places an emphasis on continuous mutable ecologies, is key to a more sustainable future. She describes four experimental projects that are ground-breaking in their treatment of the relationship between the aquatic and terra firma. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

There is overwhelming evidence from research in the regional sciences that the attitudes, values, and behaviors of Americans are geographically clustered. Psychologists, however, have historically had little to say about regional differences. This article aims to redress that neglect. In so doing, I provide evidence that there are statewide personality differences across the United States, offer potential explanations for those differences, and show that regional personality differences are linked to a variety of important social indicators. I also explain how a regional perspective can inform research in a variety of areas in psychology and suggest ways in which researchers can study regional differences in their own work. Ultimately, this work is intended to raise awareness in psychology about the value that a regional perspective can add to theory and research.
