Beef ranchers in British Columbia rely upon Crown range for a large proportion of their summer and fall grazing needs. Any improvement in the management policies for this resource can enhance the economic viability of the beef sector. The objective of this study is to evaluate the stocking levels of stock ranges administered by range agrologists and to compare their assessment with that derived using a more formal planning procedure. The report details the stocking capacity for the Punchaw Stock Range in the Prince George range district. Capacities for other stock ranges are also estimated. When rotational uses are defined and examined, the optimal use pattern results in carrying capacities that are approximately double that of current or recommended stocking levels. Les producteurs de bovins de Colombie-Britannique dépendent des parcours de la Couronne pourune grande partie de leurs besoins en pâturages ?été et ?automne. Toute amélioration des politiques de gestion de cette ressource risque ?avoir un effet salutaire sur la viabilité économique du secteur des bovins. La présente étude avait pour objectif ?évaluer ?intensity de pâturage sur les parcours gérés par des agronomes et de comparer leur évaluation à celle obtenue au moyen ?une méthode de planification répondant à des critères plus officiels. Nous fournissons des données détaillées sur la capacité de charge correspondant du parcours Punchaw, dans le district Prince George. Nous procédons en outre à ?évaluation de la capacité de charge ?autres parcours. Lorsque ?exploitation en rotation est définie et examinée, le calcul de ?utilisation optimale donne une capacité de charge correspondant approximativement au double des valeurs actuelles ou recommandées. 相似文献

There are two types of micro-states, islands and mainland ones. Except for a few islands very close to the coast, most of the insular micro-states are demographically very different from the rest of the Third World. Their death-rates are lower, their birth-rates lower, and the propensity of their populations to migrate to developed countries higher. It is argued here that these differences are based on other social and economic differences, which can be summarized by saying that such states are more Westernized. They were part of the European maritime system at a time when the West did not have the economic strength to penetrate continental areas to the same extent. On the whole they retained colonial links longer. 相似文献

The objectives of this study were as follows: (1) Formulate a theoretical model of the typical medical practice as a system for producing medical care, with particular attention to the role of middle-level health workers such as graduates of Duke University's Physician's Associate Program. (2) Develop a methodology for collecting data necessary to estimate the relevant parameters in the model, and to describe current patterns of utilization of Duke PA's. (3) Draw substantive conclusions, insofar as the model and data collection methodology permit, about the actual and potential productivity of Duke PA's.As of October 1971 Duke University had graduated 68 PA's from its Physician's Associate Program. Of these, 34 are employed as assistants in family practice or general medicine in a variety of private and institutional settings. Data were collected on eleven of these 34 PA's. No attempt was made to study the other 34 graduates engaged in clinical specialties, administration, or other functions. Neither was any attempt made to collect data on or draw inferences about the utilization and productivity of graduates of any other program such as the MEDEX Program.4 相似文献

This analysis seeks to relate the processes of different production modes to product characteristics and incomes of consumers within a particular industry. A dynamic interpretation of the cross-sectional relationships suggests that with rising incomes consumers pass through the product and process characteristics of the earliest pre-capitalist formations to those of successively later periods. 相似文献

Technology has always had an influence on the form of settlements, but only since the coming of Information Technology has it aroused much interest from academics and planners. The impact that IT is likely to have on urban areas is debated, some foreseeing decentralisation and the end of place, while others see evidence of the centralisation of control in a global economy. Other new technologies may also affect cities as new materials provide the opportunity for different styles of building. As we enter the 21st century, however, we do so with the largest stock of urban capital ever, much of which is ageing and in need of maintenance. Technology is part of a complex interrelationship of influences on urban areas and much of it will have to be retrofitted on to the pre-existing environment. 相似文献

Using Piaget's (1970) theory of cognitive development, the present study examines when children first begin to demonstrate team loyalty. An interview and testing protocol was administered to children aged 5-6 and 8-9. Preoperational, transitional, and concrete operational children were capable of demonstrating a psychological commitment to a favorite team that was resistant to change, but not the behavioral consistency indicative of loyalty. The current study demonstrates that children form preferences for sports teams early in life and that they are capable of forming a commitment to a sports team as young as age 5. The present study is one of the first efforts to include a transitional phase in the assessment of cognitive development. Results from the interviews showed that fathers were the most influential socializing agent relative to introducing children to sports teams and that the gender stereotype associating sports with males was prevalent among children in both age groups. 相似文献

An understanding of customers’ perceptions of value is fundamental to the competitive nature of all industries. Using the timeshare resort sector as a context for our studies, we explore the ways in which consumers, grouped according to their timeshare ownership stage, perceive value. Data were collected from three samples: non-owners of timeshare, recent purchasers of timeshare, and longer-term timeshare owners. Value was shown to be multi-dimensional, with a stable pattern of eleven correlated value factors evident in all three samples. The groups differed in their assessments of the different dimensions of value. In all groups, however, value was positively correlated with attitudes and future intentions regarding timeshare. Self-image congruency explained additional criterion variance. The findings demonstrate that, even among consumers who have never used timeshare, value and self-image congruency are substantial and unique predictors of attitudes and intentions regarding this tourism product. 相似文献
