Over the past 30 years, the responsibilities, mandates, and activities of local governments in Ontario have undergone substantial transformations. Influenced by New Public Management, policy changes are characterized by marketization and managerialism resulting in downloading of responsibilities to local governments. This research examines the ebbs and flows of policy changes among different provincial governments since 1990 and the impacts of these policies on rural local governments in Ontario. Interviews were conducted with elected officials and senior staff in eight local governments to understand their realities. The findings demonstrate the continual policy changes led to the “do more, with less” approach currently faced by rural local governments—increased regulatory requirements, limited human and financial capacities, and small tax bases to support their activities. This experience, combined with limited fiscal levers, hinders the ability of rural local governments to address both new demands for infrastructure and existing infrastructure deficits, housing stock and affordability, and economic and workforce development strategies. The reality has necessitated local governments to seek alternative strategies to deliver programs and services through partnerships and collaboration. 相似文献

Hobbes is commonly treated as a foundational figure for liberalism. This familiar view relies on emphasizing his account of the relationship between rights bearing individuals and state power. By contrast, this essay centers the practical question of how to govern, and develops this perspective to both question Hobbes's supposed liberalism and to demonstrate the utility of construing liberalism as more than a set of philosophical arguments regarding subject-state relations. In particular, understanding liberalism in terms of political technique offers a new perspective on the relationship between liberalism and republicanism. 相似文献

Investigating plants used for building and craft activities is important for understanding how environments surrounding archaeological settlements were exploited, as well as for considering the social practices involved in the creation and use of plant objects. Evidence for such plant uses has been observed at many Near Eastern Neolithic sites but not widely discussed. Survival may occur in a number of ways, including as impressions in clay, and as charred or desiccated macroremains. Another, less well-known, way in which plant artifacts can be found is as silica skeletons (phytoliths). Formed by the in situ decay of plants, their analysis may tell us about taxa exploited, and locations in which plant artifacts were used or discarded. At Çatalhöyük, an abundance of silicified traces of plants used in building materials and for craft activities survive, and are found in domestic and burial contexts. Their analysis demonstrates the routine use of wild plants, especially from wetland areas, for basketry (mats, baskets and cordage) and construction, as well as the secondary use of cereal husk chaff in certain types of building materials. The numerous finds suggest that plant-based containers played an important role as an artifactual class, even after the adoption of early pottery. 相似文献

The construction of mortality profiles to investigate age-at-death patterns is a typical component of most faunal analyses. While many methods exist for constructing and comparing mortality profiles, plotting the percentages of juvenile, prime, and old individuals on a triangular graph, or ternary diagram, remains a popular method for making comparisons. Typically, these comparisons are made visually, but because sample sizes are often small, any differences may be the product of sampling rather than meaningful contrasts in depositional history. To overcome this problem, here we present a likelihood-based method for making statistical comparisons of mortality profiles on a triangular graph, and we make available a cross-platform computer program that implements the method. Although we developed the method with mortality profiles in mind, in principle, it can be used to analyze any kind of artifact for which there are three distinct categories. 相似文献

Recently, several accessibility measures using the space–time prism concept have been suggested in the literature. These measures fail to take into account (i) the ability of individuals to adjust their activity–travel patterns in coping with constrained choice sets, (ii) uncertainty in the perception of travel times, (iii) temporal variability of travel times, and (iv) the influence of travel information on accessibility. The aim of the present article is to contribute to this literature by addressing these four shortcomings. Theory will be developed and illustrated using numerical simulations. The results suggest that the accessibility measure proposed in this article is a useful indicator of social inclusion in terms of the time individuals can spend to conduct their preferred activities. Moreover, accessibility is found to be affected by the presence of schedule delay penalties, restrictions in time allocation to activities, and the provision of travel time information in order to reduce uncertainty. 相似文献
