Home range is commonly understood to be the distance from home that children are allowed to go in the outdoor environment with the term being used within various academic disciplines. Different factors influence children's home range including traffic, age, parental fears and understandings of what it means to be a good parent. Research addressing home range over different generations has identified a context of changes in the built environment, demography and technology. This paper reports results from three generations of two families in Sheffield in the north of England and confirms a reduction in four major domains: home range, variety of outdoor spaces visited, range of activities undertaken and the number of companions.  相似文献

This article inquires into the difference between philosophy as a universal practice and philosophy as a cultural product; its aim is to establish a case for there being Canadian philosophy. Philosophy as a practice can exhibit a dialectical framework. The practice can pursue both universal truths and cultural variations in expressions of those truths. Each philosophical endeavor requires the other to be meaningful. No matter how abstract a “truth” may be, an example always creates cultural relevance. The article introduces the example of an early Canadian philosopher, whose work is documented in the book by Leslie Armour and Elizabeth Trott, The Faces of Reason: An Essay on Philosophy and Culture in English Canada, 1850-1950. John Watson (1847–1939) was the most prolific and well-known contributor to philosophy in early Canada, pursuing universal questions and yet responding to the circumstances of his new home in developing Canada and, in doing so, contributing to Canadian cultural interpretations of philosophical questions. This article uses his example to conclude that the study of philosophy in Canada must include Canadian philosophy.  相似文献

Contemporary Australian Indigenous policy changes rapidly and regularly fails to deliver its stated aims. Additionally, political and social relationships between Aboriginal and Torres Strait Islander peoples and the Australian state remain complex and contested. This article draws on critical Indigenous theory, alongside the increasingly influential scholarly paradigm of settler colonialism, to draw these two elements together. It highlights the ongoing nature of colonial conflict, and the partisan nature of state institutions and processes. While policy is usually framed as a depoliticised, technical practice of public management for Indigenous wellbeing, I suggest that it also seeks to ‘domesticate’ Aboriginal and Torres Strait Islander peoples, perform their dysfunction and demonstrate state legitimacy. This is especially the case in Australia, which has a long tradition of framing domestic welfare policy – rather than legal agreements – as the ‘solution’ to settler colonial conflict.  相似文献

We have investigated the survival of PCR-amplifiable mitochondrial and nuclear DNA in a small number of modern and medieval bovine leather samples. The results of this preliminary investigation demonstrate that, while no nuclear DNA can be PCR-amplified from any of the specimens, mitochondrial DNA can be amplified from all samples. To investigate this contrasting pattern of DNA survival further, we have vegetable-tanned cow skin in our own laboratory, and directly assayed the survival of PCR-amplifiable mitochondrial and nuclear DNA at each step of the process. The results indicate that nuclear DNA is reduced to sub-amplifiable levels as a result of the tanning baths, whereas amplifiable mitochondrial DNA survives the complete process. Our results suggest that old and archaeological bovine leather may represent a useful source of genetic information, although this information will most likely be limited to that which can be gained from mitochondrial DNA.  相似文献

Despite sustained attention to the role of stakeholders in policymaking—both in legislative and regulatory venues—we lack a systematic understanding of whether and when stakeholders wield influence over decisions. This is particularly true regarding state-level rulemaking in the United States, which has become an important venue of policy action as federal policymaking is increasingly stymied. Although the specifics of the rulemaking process vary to some degree across states, determining whether common patterns of stakeholder influence exist across states and issue areas can advance our understanding of regulatory institutions more broadly. This study contributes to the growing body of scholarship on state-level rulemaking by analyzing the ways in which stakeholders participate in rulemaking processes and the effects on rulemaking decisions of such participation in three policy domains across five states. We find that while industry may be influential during rulemaking across cases, consequential opportunities for non-industry stakeholders to influence regulatory decisions also exist.  相似文献
