This article explores young people's practices in the virtual spaces of online gaming communities. Based on a three-year field-study of virtual worlds, it considers how young people construct and maintain identities within virtual social systems. The article discusses the relationship between the material and virtual aspects of young people's leisure. It suggests that the boundaries between these domains are porous. Virtual worlds offer spaces for the imagination and can enhance agency and, potentially, resistance. However, virtuality is no ‘liberated space’ and it incorporates norms and practices that often mirror those of the material world. 相似文献

The processes of modernisation that re-capitalised London in the post-war period can be located in both dominant and resistant movements. Many aspects of the city's discursive fabric in the 1950s and 1960s were underpinned by a similar geographical imagination. This geographical imagination was characterised by a desire to visualise and represent nature and the real afresh and can be found in modernist architecture and planning aesthetics, Pop Art, Op Art, Angry realist writing, the style of Swinging London, and the tactics of counter-cultural rebellion in the city. Acknowledged geographies of modernity and anti-modernity are therefore questionable. Similarly, the geographies of power and resistance are constituted by more than spatial tactics and moral or behavioural boundaries as they are often rendered. An approach that understands hegemonic processes in terms of geographical imaginations allows an analysis that moves beyond outward manifestations of resistance and enables an engagement with the less palpable aspects of dissent such as ideology and aesthetics. 相似文献

This paper contributes to our understandings of the geographies of science through an analysis of nineteenth–century natural history and, in particular, of the provincial natural history society. Focusing on nineteenth–century Cornwall and one of the main natural history societies operating in the county at that time – the Penzance Natural History and Antiquarian Society – it is argued that a set of key spaces were integral to the operations and outputs of such societies. The paper details the significance of the Penzance Society's museum, field sites and lecture hall as sites for communal work of local natural historians. They were also important, it is argued, in their construction of West Cornwall as a site of national natural scientific importance. Lastly, these spaces defined an agenda for regional scientific study. In particular, they promoted a taxonomic method that would transform local people into rigorous scientists and the local region into a 'book of nature'. 相似文献

‘Black Economic Empowerment’ (BEE) has been a major policy thrust of the democratic governments in South Africa since 1994 in attempting to redress the effects of apartheid. In this article, we explore the historical precedents to BEE in South Africa, review the different steps taken in promoting it, and assess some of its outcomes to date. We argue that BEE can take only limited forms because of the economic policy constraints in which it has been incorporated. Moreover, these forms have an increasingly managerial logic that further restricts what can be achieved. Short of a major shift in conceptions of — and policy for — BEE, meaningful ‘empowerment’ is unlikely to take place. 相似文献

Dental caries is an important condition to record in archaeological collections, but the way in which recording is carried out has a large effect on the way in which the results can be interpreted. In living populations, dental caries is a disease that shows a strong relationship with age. Both the nature of carious lesions and their frequency change with successive age groups from childhood to elderly adulthood. There is also a progression in the particular teeth in the dentition which are most commonly affected and, in general, the molars and premolars are involved much more frequently than the canines and incisors. Lower teeth are usually affected more than upper, although the condition usually involves the right and left sides fairly equally. In the high tooth wear rate populations represented by many archaeological and museum collections, there is a complex relationship between the form of lesions and the state of wear, which adds yet another range of factors to the changing pattern of caries with increasing age. In the same populations, chipping, fracture and anomalous abrasion of teeth are also common, and these contribute similarly to the distribution and forms of carious lesion observed. Amongst the living, the pattern of ante‐mortem tooth loss is important in understanding caries and, in archaeological material, there is also the complicating factor of post‐mortem tooth loss. Finally, there is the question of diagnosis. There are diagnostic problems even in epidemiological studies of living patients and, for archaeological specimens, diagenetic change and the variable preservation of different parts of the dentition add further complications. For all these reasons, it is difficult to define any one general index of dental caries to represent the complete dentition of each individual, which would be universally suitable for studying a full range of collections from archaeological sites or museums. Variation in the nature of collections, their preservation, tooth wear, and ante‐mortem and post‐mortem tooth loss mean that when such a general index appears to differ between sites, there could be many other reasons for this, in addition to any genuine differences in caries incidence and pattern that might have been present. It is suggested here that the best approach is instead to make comparisons separately for each tooth type, age group, sex, lesion type and potential lesion site on the tooth.

Poll results vary over the course of a campaign election and across polling organisations, making it difficult to track genuine changes in voter support. I present a statistical model that tracks changes in voter support over time by pooling the polls, and corrects for variation across polling organisations due to biases known as ‘house effects’. The result is a less biased and more precise estimate of vote intentions than is possible from any one poll alone. I use five series of polls fielded over the 2004 Australian federal election campaign (ACNielsen, the ANU/ninemsn online poll, Galaxy, Newspoll, and Roy Morgan) to generate daily estimates of the Coalition's share of two-party preferred (2PP) and first preference vote intentions. Over the course of the campaign there is about a 4 percentage point swing to the Coalition in first preference vote share (and a smaller swing in 2PP terms), that begins prior to the formal announcement of the election, but is complete shortly after the leader debates. The ANU/ninemsn online poll and Morgan are found to have large and statistically significant biases, while, generally, the three phone polls have small and/or statistically insignificant biases, with ACNielsen and (in particular) Galaxy performing quite well in 2004. 相似文献

Abstract. The paper proposes a human capital‐based model of choice between paid employment and entrepreneurship that can give rise to multiple equilibria in occupational structure. The model is consistent with evidence of pronounced, persistent, and hitherto unexplained regional variations in entrepreneurship. Whether multiple equilibria emerge is shown to depend on the occupation‐specific productivity of human capital and the costs of human and financial capital. The paper goes on to discuss the implications for governments seeking to promote entrepreneurship as a tool of regional development policy. 相似文献
