Rural communities and well‐being: a good place to grow up? 总被引:1,自引:0,他引:1
Anthony Glendinning Mark Nuttall Leo Hendry Marion Kloep Sheila Wood 《The Sociological review》2003,51(1):129-156
This study looks at young people's accounts of life in communities in rural northern Scotland, and considers in what ways affective and social aspects of community are bound up with well‐being, over and above young people's concerns for the future, rural youth transitions, and out‐migration. Interviews were held with 15–18 year‐olds in four study areas (16 groups, N=60+) and a parallel survey of 11–16 year‐olds was conducted in eight study areas (N=2400+). Themes to emerge from the interviews included: opportunities locally, the future and staying on, as well as local amenities and services; but older teenagers also spoke at length about their social lives, family and social networks, and their community, both as close‐knit and caring and as intrusive and controlling. Rural communities were seen as good places in childhood, but not necessarily for young people. In parallel with that, the survey data paints a picture where feelings of support, control, autonomy, and attachment were all associated with emotional well‐being. Importantly, links between emotional well‐being and practical, material concerns were outweighed by positive identifications of community as close‐knit and caring; and equally, by negative identifications as intrusive and constraining, where the latter was felt more strongly by young women. Certainly, beliefs about future employment and educational opportunities were also linked to well‐being, but that was over and above, and independently of, affective and social aspects of community life. Additionally, migration intentions were also bound up with sense of self and well‐being, and with feelings about community life; and links between thoughts about leaving and community life as controlling and constraining were, yet again, felt more strongly by young women. Thus, gender was a key dimension affecting young people's feelings about their communities with significant implications for well‐being, and out‐migration. The study illustrates the importance of understanding the experiences young people have of growing up in rural areas, and how they evaluate those experiences: particularly, how life in rural communities matters for young people's well‐being; and especially, for young women. 相似文献

Correlated Inputs in Quantitative Risk Assessment: The Effects of Distributional Shape 总被引:1,自引:0,他引:1
Application of Monte Carlo simulation methods to quantitative risk assessment are becoming increasingly popular. With this methodology, investigators have become concerned about correlations among input variables which might affect the resulting distribution of risk. We show that the choice of input distributions in these simulations likely has a larger effect on the resultant risk distribution than does the inclusion or exclusion of correlations. Previous investigators have studied the effect of correlated input variables for the addition of variables with any underlying distribution and for the product of lognormally distributed variables. The effects in the main part of the distribution are small unless the correlation and variances are large. We extend this work by considering addition, multiplication and division of two variables with assumed normal, lognormal, uniform and triangular distributions. For all possible pairwise combinations, we find that the effects of correlated input variables are similar to those observed for lognormal distributions, and thus relatively small overall. The effect of using different distributions, however, can be large. 相似文献

The quest continues for a Code of Conduct embracing universal principles which will provide guidelines and norms for corporate decision making in our increasingly complex world of global business. The search continues to identify those criteria which will enable the corporate leadership, especially those engaged in international business to be more morally sensitive and to make better ethical decisions. This article will report on an ambitious initiative designed to achieve that goal: to develop through consultation and consensus new Guidelines for International Corporations. 相似文献

The number of students accumulating credit card debt--and the amount of debt itself--on college campuses is increasing. If high-risk credit and health behavior are associated, health behavior interventions might apply to high-risk credit behavior. OBJECTIVE: The authors' purpose was to examine these possible associations. PARTICIPANTS AND METHODS: They used a retrospective design with existing data from a sample of 45,213 US college students and several ordinal regression models, which corresponded with high priority college health issues. RESULTS: Students with high-risk credit behavior were more likely to have driven after drinking, used amphetamines in the previous 30 days, felt functionally impaired by depression in the previous 12 months, had a higher body mass index (BMI), or had a lower grade-point average (GPA). They were less likely to have participated in vigorous physical activity, used condoms for oral or vaginal sex in the prior 30 days, or used marijuana. The findings support the notion that high-risk health and credit behaviors are associated. CONCLUSIONS: Further research could clarify the nature of this relation. 相似文献

The aim of this study is to investigate whether newborns detect a face on the basis of a Gestalt representation based on first‐order relational information (i.e., the basic arrangement of face features) by using Mooney stimuli. The incomplete 2‐tone Mooney stimuli were used because they preclude focusing both on the local features (i.e., the fine details of the individual features) and on the second‐order relational information (i.e., the distance between the internal elements); therefore, face detection can rely only on a Gestalt representation of a face. Two experiments were carried out by using a preferential looking procedure. Experiment 1 demonstrated that newborns prefer upright Mooney faces to inverted Mooney faces (180° rotated). Experiment 2 showed that newborns prefer a Mooney face as compared to a Mooney‐like object equated for the number of elements in the upper part. Overall, the results indicate that newborns bind and organize the fragmentary parts of the Mooneized face stimulus into a whole and detect the first‐order relations of a face on the basis of holistic processing. 相似文献

Nestedness among species assemblages implies that sites of lower species richness are subsets of richer sites in a regional species pool. This nestedness is a reflection of a non-random process of species loss as a consequence of factors that promote the disaggregation of assemblages. The impoverishment of assemblage diversity is more often observed in fragmented landscapes. This non-random process has important implications for conservation. We recorded 95 species of anurans across 22 protected areas, of which 11 sites were in an urban matrix and 11 were in a non-urban matrix. We found that sites in the urban matrix had lower richness and high values of nestedness with no spatial autocorrelation among geographic distances and species composition. Thus, species were non-randomly distributed across the landscape and a nested pattern was documented from non-urban matrix sites to urban matrix sites. The impoverishment of assemblages toward the urban matrix sites may suggest that protected areas in an urban matrix are less suitable for anuran conservation than those in a non-urban matrix sites. Both the ecological revitalization of protected areas in urban matrix and protection of non-urban forested sites are needed for the conservation of Neotropical anurans. 相似文献

This article deals with random projections applied as a data reduction technique for Bayesian regression analysis. We show sufficient conditions under which the entire d-dimensional distribution is approximately preserved under random projections by reducing the number of data points from n to \(k\in O({\text {poly}}(d/\varepsilon ))\) in the case \(n\gg d\). Under mild assumptions, we prove that evaluating a Gaussian likelihood function based on the projected data instead of the original data yields a \((1+O(\varepsilon ))\)-approximation in terms of the \(\ell _2\) Wasserstein distance. Our main result shows that the posterior distribution of Bayesian linear regression is approximated up to a small error depending on only an \(\varepsilon \)-fraction of its defining parameters. This holds when using arbitrary Gaussian priors or the degenerate case of uniform distributions over \(\mathbb {R}^d\) for \(\beta \). Our empirical evaluations involve different simulated settings of Bayesian linear regression. Our experiments underline that the proposed method is able to recover the regression model up to small error while considerably reducing the total running time. 相似文献

This article explores the ‘Kids’ Skills’ and ‘Mission Possible’ models of solution-focused brief therapy (SFBT) with children and adolescents. Both models are presented, compared, revised, and expanded with further ideas and therapeutic tools in three crucial areas: 1. Future direction, 2. Resources, and 3. Initiation of change (action). Future direction is expanded by preferred future, skill(s), and goal(s). Resources is expanded by ‘small talk,’ progress and confidence scales, exceptions, metaphors, and engagement of supporters. Initiation of change (action) goes beyond practicing the skill to experiments or steps towards the goal. This gives more flexibility to therapists using SFBT with their clients. All this is illustrated with case examples. 相似文献

Due to differences in definitions and measurement methods, cross-country comparisons of international migration patterns are difficult and confusing. Emigration numbers reported by sending countries tend to differ from the corresponding immigration numbers reported by receiving countries. In this paper, a methodology is presented to achieve harmonised estimates of migration flows benchmarked to a specific definition of duration. This methodology accounts for both differences in definitions and the effects of measurement error due to, for example, under reporting and sampling fluctuations. More specifically, the differences between the two sets of reported data are overcome by estimating a set of adjustment factors for each country’s immigration and emigration data. The adjusted data take into account any special cases where the origin–destination patterns do not match the overall patterns. The new method for harmonising migration flows that we present is based on earlier efforts by Poulain (European Journal of Population, 9(4): 353–381 1993, Working Paper 12, joint ECE-Eurostat Work Session on Migration Statistics, Geneva, Switzerland 1999) and is illustrated for movements between 19 European countries from 2002 to 2007. The results represent a reliable and consistent set of international migration flows that can be used for understanding recent changes in migration patterns, as inputs into population projections and for developing evidence-based migration policies. 相似文献

We introduce some simple models that can be viewed as special cases of the general model and general approach to analyzing the association in multiway tables that we first presented in 1998. We use two empirical examples to demonstrate the flexibility and utility of the simple models introduced here and of our general approach. 相似文献
