LOCATION AND ENTREPRENEURSHIP: INSIGHTS FROM A SPATIALLY‐EXPLICIT OCCUPATIONAL CHOICE MODEL WITH AN APPLICATION TO CHILE

Occupational choice and heterogeneous managerial ability enter a spatial Dixit‐Stiglitz setting, linking location, wages and regional entrepreneurship rates. Market potential has a positive partial effect and wages a negative partial effect on the regional supply of entrepreneurs, both balancing in equilibrium with endogenous wages. Market potential increases profits, but also the opportunity cost of entrepreneurship. In the long‐run equilibrium with perfect mobility, the cut‐off level of ability determining selection into entrepreneurship will be the same across regions; moreover, regional differences in entrepreneurship rates depend only in differences in average fixed costs of firms. An empirical application is provided for Chile.     

Mapping the audit traces of interdisciplinary collaboration: bridging and blending between choreography and cognitive science

ABSTRACT

Two long-term sci–art research projects are described and positioned in the broader conceptual landscape of interdisciplinary collaboration. Both projects were aimed at understanding and augmenting choreographic decision-making and both were grounded in research conducted within a leading contemporary dance company. In each case, the work drew upon methods and theory from the cognitive sciences, and both had a direct impact on the way in which the company made new work. In the synthesis presented here the concept of an audit trace is introduced. Audit traces identify how specific classes of knowledge are used and transformed not only within the arts or sciences but also when arts practice is informed by science or when arts practice informs science.     

Hydrogen and Fuel Cell Development in China: A Review

Hydrogen and fuel cells may have a major role in the future energy market if governments give a high priority to reduction of CO₂ emissions with associated R&D investment in efficient hydrogen technologies. It is predicted that China would have the highest share of hydrogen fuel cell vehicles in 2050 if their ambitious climate and energy security policies are adopted (OECD (Organisation for Economic Co-operation and Development)/IEA (International Energy Agency) (2005) Prospects for Hydrogen and Fuel Cells (Paris: OECD Publications)). R&D in hydrogen and fuel cell technologies in China has been pushed by the central government's commitment to reduce air pollution emissions from transportation, to enhance energy security and improve national competitiveness. The paper focuses on current policies and progress on hydrogen and fuel cell development in China. Development prospects and challenges are discussed with a view to achieving better understanding of the emerging hydrogen economy.     

THE RENEWED VIABILITY OF GRAIN CORN PRODUCTION IN SOUTHERN ONTARIO, 1961–1971, AND CHANGES IN HARVESTING AND STORAGE METHODS

The decade 1961–1971 was one of remarkable expansion in grain corn production across southern Ontario, most notably reflected by the increase in the average scale of production. The complex of factors related to the renewed viability of the crop is discussed, with particular attention to developments in harvesting and storage methods. This serves to illustrate the process by which new developments in harvesting and storage methods were adopted and relates technological change to the economics of grain corn production and adaptive decision-making.
De 1961 à 1971, l'ensemble du Sud de l'Ontario a connu une expansion remarquable de la production de grains de maïs, une expansion surtout reflétée par une augmentation notable du niveau moyen de production. Dans notre article, nous discutons les facteurs complexes reliés à ce renouveau de la viabilité du maïs. Nous nous concentrons sur le développement des méthodes de récolte et d'entreposage. Notre perspective nous permet d'illustrer le processus d'adoption des nouvelles méthodes de récolte et d'entreposage, et de lier le changement technologique à l'économie de la production de grains de maüs et aux prises de décisions conséquentes.
