The purpose of this brief editorial is to discuss psychology in Québec and some of the foremost researchers who have had a recognized world-wide impact on psychology. Following a brief review of historical facts describing the evolution of psychology in Québec, and of issues related to communicating psychology in French, the contribution of certain distinguished individuals is highlighted. These persons either have played a critical role in international organisations, or have produced scientific work that is widely recognized by their peers.

Travel behavior data collection methodologies have not captured the why of demand nor unsatisfied demand. This has left a gap in the development of methodology that can adequately address the role that transport plays in fostering social exclusion. This paper presents one innovative technique that utilizes GIS to organize and analyze data taken from focus groups and the self-mapping of individual space. Implications for transportation planning include redefining how networks are conceived to include not just road and bus networks, but also the spatio-temporal networks constructed by low-income people as they organize their activities.  相似文献

The purpose of this brief editorial is to discuss Québec psychology and some of the foremost researchers who have had a recognized, world-wide impact on psychology. Following a brief review of historical facts describing the evolution of psychology in Québec, and of issues related to communicating psychology in French, the contribution of certain distinguished individuals is highlighted. These persons either have played a critical role in international organisations, or have produced scientific work that is widely recognized by their peers.

Collaborative innovation spaces (CIS) can bring together multiple actors to enhance creativity, collaboration and knowledge exchange, sometimes leading to innovation. In this paper, we suggest that CIS can be categorized into three broad types (internal to the firm, external and virtual) and that each type is related to innovation processes, knowledge-sourcing and geographic context in specific ways. Our results, based on an original firm-level survey, reveal that there is heterogeneity with respect to firm attributes and innovation activities associated with different types of CIS. In particular, whilst innovation is associated with the use of CIS in general, radical and technological innovations are more strongly associated with internal CIS, whereas smaller firms tend to use virtual CIS. External CIS, whilst not associated with technological innovation, are associated with high-tech firms. CIS use does not vary across geographic context. These results emphasize the importance of in-person, internal, CIS for radical and technological innovation and the need to distinguish between different types of CIS in order to understand how each is associated with different types of innovation, knowledge-sourcing and firm.  相似文献

This paper examines how KIBS establishments combine innovation and exports, and which factors are associated with these combinations. In particular, we hypothesize that KIBS establishments which both export and innovate will be over-represented in metropolitan regions, and under-represented in peripheral regions. Our analysis draws upon a sample of 429 innovative KIBS establishments in the province of Quebec (Canada). We show that strategies differ across space (but not as expected – metropolitan and peripheral strategies are similar), that T-KIBS’ strategies are associated with non-market information sources, and that P-KIBS' strategies are associated with information purchasing. P-KIBS’ and T-KIBS’ strategies vary with the performance of in-house R&D. Taken together, these results suggest that whereas KIBS’ choice of export and innovation strategies do not reflect their ‘hard’ or ‘soft’ nature, the factors associated with this choice do. The similarity between metropolitan and peripheral regions reflects the fact that Quebec’s resource-based peripheral economy is international and innovative.  相似文献

Reviews the book, Conflict and language planning in Quebec by Richard Y. Bourhis. This monograph, edited by Bourhis, makes a distinct contribution to scholarship in the area of Language Policy/Language Planning (LP) in general, and more specifically, to research in that area within Canada. Work in this area is almost always collaboratively undertaken and involves individuals from diverse disciplinary backgrounds. These trends are evident in the present monograph. The major contributions of this monograph are threefold: first, it leads to a better understanding of the language situation in Quebec; secondly, it describes clearly three of the four major components of LP activities--planning, policy formulation and implementation; and thirdly, authors present an interesting array of methodological techniques not typically used by many LP researchers, by which one can further investigate empirically reactions or responses to language policy change in various settings. The attractiveness of the monograph derives from the interesting and clear account of a major planned social change within the province of Quebec which has had provincial and national implications for concerned Canadian residents, but which more importantly has had immediate implications--at both theoretical and applied levels--for language policy scholars throughout the world. This monograph comprises a welcome addition to the rapidly growing literature which examines the role of language in national development. It provides careful documentation of a fascinating case study of one set of events that have been carefully chronicled by well-trained scholars from diverse disciplinary perspectives.

Although recent landscape changes have been extensively studied, we possess very little information about the nature and extent of changes before aerial photographs were available. To contribute to this knowledge, we propose to explore the information within the Canadian censuses of the nineteenth century, documentary sources still very underused in landscape dynamics studies. The importance of these data lies in the fact that information is provided at the scale of each lot between 1842 and 1871, and at the township scale for subsequent years (1881–1951). In this study, nominative data provided for a rural township (139 km2) located in southern Quebec were coupled with detailed information about geomorphologic features using GIS.The analyses indicated two main phenomena. First, characterization of global landscape dynamics revealed the extent and rapidity of change. The evolution of land-use shows an increase of about 40% in improved areas between 1842 and 1871. while cumulative data show improved areas occupying nearly 83% of the total areas in 1891. These results contrast with recent landscape dynamics (1958–1993) which display relatively minor changes. Second, at the landscape type scale as well as at the surface deposit scale, analysis of nominative data failed to show any clear relationship between landscape dynamics and the spatial entities considered, whereas recent land-use patterns are closely linked to surface deposits. Thus, constant fluctuation in the agroforestry landscape and the lack of influence of abiotic characteristics on land-use dynamics represent two specific characteristics of this nineteenth century landscape.  相似文献
