Using Current Population Survey data, this paper examines the extent to which a person's resources impact his or her ability to participate in computer-mediated political life. Resources such as universal literacy, background capacities, skills, and training clarify the well-documented but poorly conceptualized gap in technology access between "haves" and "have nots." Telecommunications policy does not address seriously the resources one brings to the table beyond perfunctory attention to what is affordable. Until resource disparities are examined more closely by policymakers, the divide in access to the computer-mediated political public sphere likely will continue to expand. 相似文献

This article examines the place of religious values in the thinking of leading figures in the mainstream German women's movement in the period before World War I. Focusing on the debate of sexual morality and abortion within the German League of Women's Associations, it argues that the position taken by these women is best understood as a product of their religious commitments, rather than their political ideas. The article seeks to place these women in the historical context of a particular liberal, Protestant, social and intellectual milieu that flourished in the period before 1914. 相似文献

We undertook combined stable carbon, nitrogen and sulphur isotope analysis of marine and terrestrial faunal remains from two prehistoric coastal shell middens in Denmark. The aim of the investigation was to establish whether sulphur isotopes were useful in discriminating terrestrial and marine consumers in this region. We found that sulphur isotopes do separate marine and terrestrial fauna but, contrary to our expectations, we observed a negative correlation between δ34S and δ13C values for marine fauna. We conclude that similar studies over a broader geographical range are needed before sulphur isotopes can be reliably used to study coastal resource exploitation. 相似文献

This paper examines the trends in residential segregation by income (post-transfer, pretax income) in the thirty-nine largest Canadian urban areas between 1991 and 1996. The study is motivated by the relative lack of attention paid to residential segregation by income in the Canadian context and by conceptual arguments linking compromised life chances and increased social tensions for the populations of highly segregated cities. We investigated several dimensions of segregation using five different measures (we focus on three of these here given the correlation structure of the measures) to examine changes in segregation between 1991 and 1996, a period characterised by economic recession, cutbacks in social programs and a widening of inequality in market incomes at the national scale. Overall, income segregation increased in most urban areas across all dimensions of segregation during the time period, with particularly high degrees of segregation observed in prairie cities (Winnipeg, Saskatoon and Regina). Of the three largest metropolitan areas (Vancouver, Toronto and Montréal), Montréal was the most consistently segregated. We also find that increases in spatial separation and spatial concentration by income occurred despite the fact that at the national scale, the tax and transfer system appeared to be adequately redressing a rise in inequality in labour and market incomes (as demonstrated by the lack of change in post-transfer national income inequality measures during a period when inequality in market and labour incomes rose sharply). This implies that the lived experience of changes in income distribution are unlikely fully captured by aspatial, national-scale measures and that intra-urban measures with a spatial dimension are an important indicators of inequality in Canadian society. 相似文献

This review article examines in detail the argument in Alfred Gell's posthumously published book Art and Agency: an anthropological theory. The review is divided into two parts. In the first I summarise the main argument of each chapter in turn and comment on some of the author's more questionable assumptions and conclusions. In the second I step back from the individual chapters and comment on three of the more general issues the book raises. 相似文献
