Social Metabolism and Labour in a Local Context: Changing Environmental Relations on Trinket Island 总被引:1,自引:0,他引:1
Singh Simron Jit Grünbühel Clemens M. Schandl Heinz Schulz Niels 《Population and environment》2001,23(1):71-104
From a material and energetic perspective, this paper outlines the patterns of society-nature interactions of a local horticultural, hunter-and-gatherer population that lives on a remote island between India and Indonesia. Based on empirical research, we present several indicators to show an economic portfolio of a local society that combines horticulture, hunting and gathering activities with elements of industrialisation and market economy. In describing these environmental relations, the study narrows its focus to the use of three socio-ecological concepts, namely socio-economic metabolism, colonising natural processes, and the energetic return on investment. Using these concepts, we show the dynamics of social and environmental transformation at a local level and the consequences this may have for sustainability. 相似文献

This is an enquiry into how eighteenth-century London's Bills of Mortality were compiled. It concludes that while they remain tolerably accurate in aggregate, particularly when considered over a number of years, they are liable to be very misleading if particular localities or parishes are considered. They are a record of registered burials-not deaths-of most of those who had been baptised as Anglicans, so they omit some burial grounds within London, and some dissenters. Crucially, they are most misleading guides to those who had died in one parish but whose family chose to have them buried in another. Several London parishes deliberately undercut their neighbours by charging lower burial fees to attract custom; others opened extra-parochial burial grounds. St Martin-in-the-Fields offers an example of the latter from 1806, but the scale of the new burial ground was not large and it was mainly confined to those who had died in the workhouse. Much more significant was the neighbouring parish of St Anne Soho, which at its peak period in the 1760s to the 1790s was alone handling the equivalent of between 2 and 5 per cent of all Anglican burials within the total area of London's Bills of Mortality. This was only one, though perhaps a particularly egregious, London parish, while the export of corpses to one's erstwhile 'home' parish demonstrates why the Bills cannot be trusted in their detailed geography, as well as providing a warning to all English population historians confronted with a sudden fall or rise in their burial totals. 相似文献

Although a marital disruption can certainly be harmful for some children, it might be beneficial to other children. Analyses on how children are affected by marital disruptions typically capture the average estimated effects (or associations) of a disruption on an outcome. Thus, the harmful effects of the disruption on some children are being averaged with the neutral and beneficial effects on other children. This could mute the estimated effect, and it could prevent the detection of significant harmful (or beneficial) effects. Using achievement test scores and an index of behavioral problems in a first-difference framework, I find evidence for the standard approach having muted estimated effects and failing to detect significant effects when the same data produce significant isolated harmful effects. 相似文献

The study systematically examined the relative relationships between perceived family and peer gambling and adolescent at-risk/problem gambling and binge-drinking. It also determined the likelihood of at-risk/problem gambling and binge-drinking as a function of the number of different social groups with perceived gambling. A multi-site high-school survey assessed gambling, alcohol use, presence of perceived excessive peer gambling (peer excess—PE), and family gambling prompting concern (family concern—FC) in 2750 high-school students. Adolescents were separately stratified into: (1) low-risk, at-risk, and problem/pathological gambling groups; and, (2) non-binge-drinking, low-frequency-binge-drinking, and high-frequency-binge-drinking groups. Multinomial logistic regression showed that relative to each other, FC and PE were associated with greater likelihoods of at-risk and problem/pathological gambling. However, only FC was associated with binge-drinking. Logistic regression revealed that adolescents who endorsed either FC or PE alone, compared to no endorsement, were more likely to have at-risk and problem/pathological gambling, relative to low-risk gambling. Adolescents who endorsed both FC and PE, compared to PE alone, were more likely to have problem/pathological gambling relative to low-risk and at-risk gambling. Relative to non-binge-drinking adolescents, those who endorsed both FC and PE were more likely to have low- and high-frequency-binge-drinking compared to FC alone or PE alone, respectively. Family and peer gambling individually contribute to adolescent at-risk/problem gambling and binge-drinking. Strategies that target adolescents as well as their closely affiliated family and peer members may be an important step towards prevention of harm-associated levels of gambling and alcohol use in youths. 相似文献

Studies of political participation typically analyze voting, contentious collective action, or membership in voluntary associations. Few scholars investigate a more mundane—but highly consequential—form of neighborhood politics: requests for basic city services. We conceptualize city service requests as a direct, instrumental contact with local government that alters the geographical distribution of public goods. We hypothesize that rates of service requests vary with the ethnic and immigrant composition of neighborhoods, due to differences in these communities’ expectations of local government. We test this hypothesis using administrative data from the City of Boston. We find neighborhoods with high concentrations of first‐generation immigrants less likely to request services, relative to need. The concentration of African Americans, however, is associated with large increases in neighborhood service requests. We conclude with implications for the study of race, inequality, and political incorporation. 相似文献

Roughly half the labor force data in the Current Population Survey (CPS) are provided by proxy respondents, and since 1979, men’s reliance on proxies has dropped dramatically while women’s reliance on proxies has increased. Few authors, however, have examined how combining these first-hand and second-hand reports may influence our understanding of long-term economic trends. We exploit the outgoing rotation group structure of the CPS by matching individual records one year apart, and we find that self-reported wages are higher than proxy-reported wages even after controlling for all time invariant characteristics. Furthermore, we find that changes in the use of proxy respondents by men and women since 1979 have made current estimates of the gender wage gap larger than they would have been without changes in reporting status. This suggests that the gender wage gap has closed more than previously estimated. We recommend that researchers combine self and proxy responses with great care, especially when analyzing time trends or making gender comparisons. 相似文献

There is increasing recognition that whilst agri-environment schemes in England have had discernable benefits, their success in relation to certain species and resources has been inhibited by the piecemeal implementation of Environmental Stewardship (ES) on the basis of single farm agreements. In this paper we examine the receptivity of farmers to the idea of landscape-scale, collaborative agri-environment schemes (cAES) based on semi-structured interviewing in three English case-study areas. Using qualitative sociocultural interpretation we argue that a lack of communication and mutual understanding between farmers; a cultural imperative for independence and timeliness, and; alternative interpretations of risk amongst farmers present potential barriers to cAES. We also argue, however, that if designed appropriately, cAES have the potential to overcome certain concerns that farmers hold about the existing ES schemes. In particular, cAES are likely to gain support from farmers where they are seen to offer greater flexibility; scope for farmer involvement in scheme design; locally targeted and clearly defined aims, and; demonstrable benefits that can be monitored as a record of success. We provide policy recommendations and suggest that cAES have the potential to deliver greater environmental benefits, whilst at the same time encouraging farmers’ participation in, and satisfaction with, agri-environment schemes. 相似文献

Few after‐school programs target alcohol and other drug (AOD) use because it is difficult to encourage a diverse group of youth to voluntarily attend. The current study describes CHOICE, a voluntary after‐school program which targeted AOD use among middle school students. Over 4,000 students across eight schools completed surveys and 15% participated in CHOICE. Analyses indicated that there were some differences between CHOICE participants and nonparticipants. For example, African American and multiethnic students were more likely to attend. Past month alcohol users were more likely to initially attend, and marijuana users were more likely to continue attendance. Thus, CHOICE reached students of different racial and ethnic groups and attracted higher risk youth who may not typically obtain prevention services. 相似文献

Currently the majority of vegetation used on shallow extensive green roofs are species of Sedum, which are able to survive in the harsh green roof environment. While mosses frequently colonize green roofs in Europe, intentional planting of mosses on green roofs is less common, especially in North America. Mosses may contribute to the ecosystem services provided by green roofs, and may act as facilitators of vascular plants. This study examined the effect of three different moss species on soil temperature, water loss rates and the growth of neighbouring vascular plant species. Overall, the presence of mosses in this experiment impacted the neighbour species differently, suggesting that mosses are best used in particular species combinations. One species of grass showed a net benefit of moss neighbours, suggesting that facilitation may be operating. Mosses reduced soil temperature relative to bare substrates; net evapotranspiration of green roof modules planted with mosses varied depending on the identity of moss and neighbour species. 相似文献
