Depuis plus d'un siècle, l'agriculture québécoise en général, et la production maraîchère en particulier, ont subi d'importantes transformations. Cette étude historique vise à comprendre comment la production maraîchère a évolué par rapport aux changements dans l'environnement décisionnel général de l'agriculture entre 1940 et 1990. L'analyse des données statiques de superficie, de production et de rendement pour 12 légumes ont permis d'identifier trois périodes, intercalées d'années transitoires, dans l'évolution de la production maraîchère référant chacune à une stratégie agricole particulière. La première (1940–1957) correspond à une stratégie agricole de type familial traditionnel; la seconde (1963–1975), à une agriculture marchande spécialisée fondée sur la maximisation des revenus à court terme par intensification; la troisième (1980–1990), à une agriculture marchande diversifiée fondée également sur une maximisation à court terme. Les facteurs externes de l'environnement décisionnel qui ont entraîné ces changements sont identifiés et discutès. For more than a century, Quebec agriculture in general, and market-gardening production in particular, have experienced important changes. This study, using a historical perspective, seeks to understand how market gardening evolved in relation to changes in the broad decision environment for agriculture between 1940 and 1990. Statistical analysis of data on the areas cultivated, production levels, and yields for 12 vegetable crops revealed three distinct periods, separated by periods of transition, in the evolution of market gardening. Each period is characterized by a particular type of agricultural development strategy. The first period (1940–1957) is characterized by a focus on the traditional family form; the second (1963–1975), by a specialized market agriculture driven by short-term income-maximization intensification; the third (1980–1990), by a diversified marketoriented agriculture, also based on short-term income maximization. External environmental factors that stimulated these changes are identified and discussed.  相似文献

Selon la plupart des modèles théoriques du climat futur, la température moyenne à l'échelle du globe devrait augmenter de 2 à 4°C dans les prochaines décennies. Les conséquences du réchauffement de la température pourraient avoir des effets sur les activités humaines, et sur la santé humaine. Dans cet article nous décrivons les effets directs sur la santé, maladies dues à la chaleur, et les effets indirects concernant les maladies à vecteurs. Les scénarios sur la croissance des décès à la suite des vagues de chaleur, et sur la diffusion des insectes vecteurs des maladies soulèvent des problèmes conceptuels et méthodologiques qui devront être résolus dans le futur si l'on veut que les résultats provenant de divers pays puissent être comparés et évalués.
Based on climate simulations by general circulation models (GCMS), mean global temperature is expected to rise by 2 to 4°C in coming decades. Such a global warming can have significant impacts on human activities, including human health. In this article, we describe the direct effects of increasing temperature on human health. Secondary effects of the influence of temperature on vector-borne diseases are also described. Different scenarios relating to increase in mortality deriving from heat waves and from the spread of diseases through insect vectors pose conceptual and methodological problems that must be confronted in the future if comparative studies are to be undertaken concerning the effect of global warming on human health in different countries.  相似文献

We suggest attention to policy regimes provides a fruitful means for joining the contributions of scholars who study policy processes with those who are concerned with governance challenges. Our research synthesis underscores the limits of existing theorizing about policy processes for problems that span multiple areas of policy and highlights the prospects for and limitations of governing beyond the boundaries of subsystems. We suggest new avenues for theorizing and research in policy processes based on the concept of a boundary‐spanning policy regime. We develop notions about this type of policy regime within the context of the broader literature about regimes in political science, discuss the forces that shape the strength and durability of such regimes, and provide a variety of examples. This synthesis challenges the focus of policy process scholars on subsystems and broadens the traditional focus on policymaking to consideration of the dynamics of governing.  相似文献

May Farhat 《Iranian studies》2014,47(2):201-216
Mashhad, the site in northeastern Iran of the shrine of the eighth Shi?i imam, is arguably one of the largest and wealthiest sacred shrines in the world. The gilded dome over the imam's mausoleum stands amidst an expansive complex of courts, monumental gateways, libraries, museums, guesthouses, and administrative offices that cater to thousands of pilgrims each year. This paper examines the period, under the aegis of the early Safavid shahs, when Mashhad was established as the preeminent Shi?i pilgrimage center in Iran. Appropriating the Timurid ecumenical vision for the shrine, the Safavid shahs refashioned the holy city into a site that celebrated the triumph of Twelver Shi?ism in the Safavid realm and reinforced Safavid claims of legitimacy. While highlighting Shah Tahmasb's personal devotion to Mashhad, and his privileging of the shrine within Safavid sacred topography, the paper focuses on Shah ?Abbas's urban reshaping of Mashhad and the architectural and institutional expansion of the shrine during his reign, thereby enhancing its status as the leading spiritual center in the Safavid empire.  相似文献

This research extends theorizing about the implications of political environments to the content of policy areas. We consider the case of Arctic policy in Canada and the United States as an example of what we label as component-driven policymaking. We show how the lack of a clear constituency and the lack of a stable policy subsystem for the Arctic create a policy environment for which the politics of particular issues dominate Arctic policymaking. The result is a policy space labeled Arctic policy that lacks policy coherence. We suggest that similar features of component-based policymaking help explain limited policy coherence for a variety of policy areas such as policies for children, families, rural areas, urban areas, and women in the United States.  相似文献

The purpose of this article is (i) to propose the concept of policy analysis as a clinical profession, (ii) to relate to the clinical intellectual processes involved in policy analysis, and (iii) following studies in other clinical disciplines, to infer implications for policy analysis and policy analysis instruction. The article will highlight notions of clinical reasoning and clinical cognitive processes relevant to policy analysis and will address reasoning errors associated with bounded rationality and uncertainty in the clinical analytic process. The article seeks to promote awareness of clinical notions and of their relevance for policy analysis practice and instruction.  相似文献
