Decreasing experiences of home range,outdoor spaces,activities and companions: changes across three generations in Sheffield in north England

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.     

The Presidency and Political Equality

When black Americans and white Americans want the president to do different things, who wins? When low-income earners prefer different government action than do middle and high-income earners, whose preferences are reflected in presidential behavior? Recent studies show that congressional behavior often most closely follows the preferences of the white and the wealthy, but we know relatively little about presidential behavior. Since the president and Congress make policy together, it is important to understand the extent of political equality in presidential behavior. We examine the degree to which presidents have provided equal representation to these groups over the past four decades. We compare the preferences of these groups for federal spending in various budget domains to presidents’ subsequent budget proposals in those domains from 1974 to 2010. Over this period, presidents’ proposals aligned more with the preferences of whites and high-income earners. However, Republican presidents are driving this overall pattern. Democratic presidents represent racial and income groups equally, but Republicans’ proposals are much more consistent with the spending preferences of whites and high-income earners. This pattern of representation reflects the composition of the president's party coalition and the spending preferences of groups within the party coalition.     

Canadian Philosophy: A Dialectical Exploration

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.     

The technical is political: settler colonialism and the Australian Indigenous policy system

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.     

The survival of PCR-amplifiable DNA in cow leather

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.
