Abstract: Activists often strategically negotiate sectoral boundaries by switching between public, private and voluntary sectors over the life course in order to pursue their aims. This paper draws on a cross‐national study that explored the extent of this inter‐sectoral movement and the specific “career pathways” activists developed in relation to governmental, private and voluntary/community sector organisations. Using an analysis of 46 biographical narratives gathered from activists in Manchester, UK and Auckland, Aotearoa New Zealand during 2007 we situate “the academy” in these life stories of activism. Teasing out from these accounts the motivations behind a turn towards tertiary education at particular moments we examine how “academia” supports and sustains individual activists while legitimising and professionalising their activism. In so doing, we track the tactical transfer of knowledge, skills and expertise effected by contact with “the academy” to make substantive and conceptual claims around the future role universities might play in the knowledge economy. 相似文献

To investigate potential human impacts on California Channel Island shellfish stocks over the past 10,000 years, we measured 1718 owl limpet shells from 19 archaeological components on San Miguel Island. Inhabiting the middle intertidal zone of Pacific Coast rocky shores, owl limpets are slow-growing mollusks that can live for 30 years and reach lengths of over 100 mm. Recent ecological studies indicate that owl limpets are highly susceptible to heavy human predation, which results in reduced mean shell sizes among Lottia populations along the coasts of Alta and Baja California. On San Miguel Island, we identified a significant trans-Holocene reduction in mean owl limpet size, beginning more than 6500 years ago and accelerating at least 4400 years ago. Fluctuations in limpet size show no clear correlation with changes in sea surface temperature and marine productivity, suggesting that increased predation by growing human populations was primarily responsible for the reduction in Lottia size over time. Our results provide further evidence that prehistoric peoples significantly influenced nearshore fisheries long before the development of the commercial and industrialized fisheries of historic times. 相似文献

Despite a comparatively ‘flat’ social structure and lack of obvious class-based cleavages, Australian society is stratified by objective, multidimensional measures of social class. Using data from a July 2015 survey of a random sample of Australian citizens, latent class analysis identifies six class types in Australian society, based on the distributions of cultural, social, and economic capital among respondents. The resulting classes are categorised as ‘precariat’, ‘ageing workers’, ‘new workers’, ‘mobile middle’, ‘emerging affluent’, and ‘established affluent’. The precariat is characterised by high numbers of retired pensioners, the ageing worker class the highest mean age, and the new worker class by its low rate of unemployment. The established middle class accounts for one quarter of the adult population, while the emergent affluent class has the youngest mean age, and the established affluent is the most advantaged. We also show Australians are acutely aware of their class identity. 相似文献

Scholars frequently use counts of populations aggregated into geographic units like census tracts to represent measures of neighborhood context. Decades of research confirm that variation in how individuals are aggregated into geographic units can dramatically alter analyses conducted with these units. While most researchers are aware of the problem, they have lacked the tools to determine its magnitude or its capacity to affect analytical results obtained using these contextual measures. Using confidential access to the complete 2010 U.S. Decennial Census, we can construct—for all persons in the U.S.—individual-specific contexts, which we group according to Census-assigned block, block group, and tract. We compare these individual-specific measures to the published statistics at each scale, and we then determine the degree to which published measures could be affected by how boundaries are drawn using a simple statistic, the standard deviation of individual context (SDIC). For three key measures (percent Black, percent Hispanic, and Entropy—a measure of ethno-racial diversity), we find that block-level Census statistics frequently contain a high degree of uncertainty meaning that they may not capture the actual context of individuals within them. More problematic, we uncover systematic spatial patterns in the uncertainty associated with contextual variables at all three scales. 相似文献

We here report the first results from a systematic research project in Mani (Southern Greece), which includes survey and test excavations. Forty-six caves, rockshelters and open-air sites in lowland settings were surveyed. Geomorphological data were collected in order to assess how geological processes affect the preservation of sites and bias site distribution patterns. Artifacts manufactured from non-local rock indicate potential raw material transfers and suggest links among the different regions of Mani, related to mobility patterns. Our research in the Mani has nearly doubled the number of known Middle Palaeolithic sites from the region and confirmed that the peninsula has the strongest ‘Neanderthal signal’ identified to date in Greece. Almost all sites are located at coastal areas. Despite the influence of Pleistocene landscape dynamics, this distribution emerges as a persistent pattern, perhaps indicating a preference for coastal locations. The Neanderthal occupation of Mani can illuminate important aspects of Middle Palaeolithic adaptation in one of the southernmost coastal regions of Europe. 相似文献
