We present new data from three village panchayats in northwest Tamil Nadu and investigate the associations between demographic and socioeconomic factors with temporary labour migration from this setting. Individual (n?=?1110) and household (n?=?278) level logistic regression models were used to demonstrate how factors at each of these levels can influence temporary labour migration trajectories. Young males were most likely to temporarily migrate for work from this region. Additionally, large households from historically disadvantaged castes with marginal land and housing were most likely to have at least one migrant member. Households with multiple migrant members appear to use temporary migration to cope with serious deprivation relative to households with only one migrant member. These findings provide a strong case that can be compared to other settings in India and can be used to inform improved policy and targeted development initiatives to support temporary migrant workers and their households.  相似文献

The relations between riverbank erosion and geomorphological variables that are thought to control or influence erosion are commonly modelled using regression. For a given river, a single regression model might befitted to data on erosion and its geomorphological controls obtained along the river's length. However, it is likely that the influence of some variables may vary with geographical location (i.e., distance upstream). For this reason, the spatially stationary regression model should be replaced with a non‐stationary equivalent. Geographically weighted regression (GWR) is a suitable choice. In this paper, GWR is extended to predict the binary presence or absence of erosion via the logistic model. This extended model was applied to data obtained from historical archives and a spatially intensive field survey of a length of 42 km of the Afon Dyfi in West Wales. The model parameters and the residual deviance of the model varied greatly with distance upstream. The practical implication of the result is that different management practices should be implemented at different locations along the river. Thus, the approach presented allowed inference of spatially varying management practice as a consequence of spatially varying geomorphological process.  相似文献

While traditional perspectives on transgender from some strands of feminism and within medical/psychoanalytical discourse have argued that transgender people conform to and reproduce gender stereotypes, queer theory has celebrated transgender as a site that highlights the social and cultural construction of ‘sex’ and ‘gender’ and, moreover, as a symbol of transgressive gender possibility. Both of these readings ignore the complexities of lived trans experiences and identifications. By evaluating a queer reading of trans through recent empirical research into transgender identities, I suggest that while trans identifications certainly queer binary models of ‘sex’ and ‘gender’, such transgressions are materially, culturally, socially and spatially contingent. The article draws on empirical research to explore the ways in which access to queer subjectivities is constrained by, and negotiated alongside, the locales of the workplace and community spaces.  相似文献

The Nene Valley, in eastern central England, was a major pottery production centre in the Roman period. Many kiln sites have been identified in the Lower Nene Valley region and, although comparatively less is known about production in the Upper Nene Valley, substantial amounts of mortaria and other coarse wares have been recovered during excavations at Roman sites in the area, and much of it is thought to be locally made. However mortaria made in the Upper and Lower Nene Valley can be difficult to tell apart, and many also have similar forms and fabrics to mortaria produced in Mancetter–Hartshill, Warwickshire. Therefore ICP analysis was used in an attempt to identify the products of different regions.  相似文献

The emergence of synthetic alkali production in Britain during the early nineteenth century was associated with pronounced regional growth. Three areas in particular developed an incipient soda industry: south‐west Lancashire, Tyneside and especially the central valley of Scotland. This paper sets out to evaluate the importance of raw materials and market structures as locational factors at a time when knowledge of this new technology was in the hands of the few and its diffusion was strongly channelled by an emerging chemical fraternity. In doing so some understanding of an industrial legacy which has proved difficult to change and impossible to obliterate is provided.  相似文献

When watching the film The Blair Witch Project we seem to be witnessing through its clumsy, apparently uncrafted footage the unmediated documentation of 'reality' as it occurs. This article argues that the carefully crafted deceit of The Blair Witch Project may be understood as part of a subversive 'public history' project that uses modern history's own scientific motifs and methodologies against itself and challenges its basic tenets. If positive myths of the past are structured into what we tend to call heritage, i.e. shared narratives affirming a positive sense of self and region or nation, then this paper argues that The Blair Witch Project takes the same notion and subverts it, giving its chosen audience a dark and unsettling sense of its own history.  相似文献
