This paper proposes an a fortiori case study method of testing Bachrach and Baratz's 1962, 1963, 1970 well-known hypotheses about the second face of power. This face of power is allegedly characterised by exclusionary agendasetting; elites exclude the interests and demands of the poor from the policy agenda. A working assumption of the paper is that exclusionary agenda-setting may be quite infrequent. If we can specify the conditions under which it is relatively likely to occur, and then investigate cases which meet most or all of these conditions, we may be able to discover the minimum set or sets of conditions which have to be met. We could then make a fortiori inferences about other less stringent sets of conditions under which it would rarely if ever occur.  相似文献

Ancient decorated potteries from Susa (Mesopotamia) dating from 4200 to 3700 bc , were studied in order to determine the origin and the nature of the raw materials used, and to identify the technological processes applied to make the ceramic bodies and their decorations. Bulk compositions were determined by particle induced X‐ray emission (PIXE), while the microstructure and the mineralogical phases were studied using scanning electron microscopy (SEM), energy dispersive X‐ray analyses (EDX) and X‐ray powder diffraction (XRD). The results showed that the raw materials used to elaborate these potteries were similar for all the ceramic bodies (carbonates and iron and magnesium‐rich clays containing sand), and for all the decorations (iron oxides, silica, potassic and alumina sources). The variations of coloration of the ceramics and of their decorations were due to different firing temperatures. The ranges of firing temperatures used by potters were evaluated on the basis of mineral stability domains.  相似文献

Cet article traite de la relation géographique entre les accidents de la route et l'intervention policière sur les routes en milieu rural. On pose la question à savoirsi les accidents se produisent généralement là ou les policiers assurent une certaine intervention et surveillance et si, réciproquement, les caractéristiques géographiques des accidents incitent des interventions spécifiques des forces publiques. L'analyse permet de constater la distribution géographique des accidents et des contraventions. If existe également des lieux communs regroupant en nombre considérable les deux types d'événements. Les courbes de distribution selon les mois, jours et heures sont toutes spécifiques. En conclusion, l'article constate que la correspondance géographique entre accidents et contraventions est caractéristique du milieu étudié mais l'inadéuation temporelle en limite la relation. On s'interroge enfin sur le fait que l'intervention policièe pourrait ne pas etre suffisamment planifiée. This article deals with the geographical aspects of highway safety in a rural area. Using two different databanks, the research attempts to establish a correlation between car accidents and the frequency of police intervention (traffic tickets) in specific geographical locations. Is there a higher frequency of highway accidents in areas where patrolmen frequently hand out tickets to motorists? Research results indicate a concentration of accidents occurring in geographic areas where tickets are frequently given out. However, the period in time when tickets are given out does not correspond to the period in time when accidents happen. In conclusion, the authors question the nature of police intervention.  相似文献

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

We explore in this essay the relatively uneven "travels" of feminist historical geography within the academy in order to highlight the realized and potential intellectual productivity that can result from bringing together a feminist and historical approach to understanding place and space. We outline in what ways much of feminist geography is already historical and in what ways much of historical geography is already feminist, and then turn to a discussion of the unevenness of these intellectual journeys. We conclude by suggesting challenges for future research in feminist historical geography.  相似文献
