Abstract Why do people engage in economically minor resource production activities? This field study of Vermont and Quebec maple syrup producers and their households and enterprises examines the diversion of motivations and concerns m contemporary maple syrup production. Farmers, former farmers, and non-farmers all produce maple syrup. The concept of embeddedness provides a framework for understanding how producers understand their involvement with maple syrup, by highlighting the social and cultural context of economic action. An embeddedness perspective emphasizes how other work activities, household relations, the surrounding community, and the resource environment shape the possibilities for and understandings of minor resource production activities. Maple syrup generally only supplemented the household income of the 76 producers interviewed. Producers articulated a cultural economy of syrup production centered on its contribution to overall livelihood, cultural identity, and lifestyle. Reasons included managing risks, making seasonal use of land and labor resources, developing a retirement income, demonstrating a rural, agrarian identity, and strengthening family and community ties. Implications for policy include the place of minor resource production activities in securing rural livelihoods and providing cultural anchors in rural regions experiencing demographic and economic change. 相似文献

The proliferation of artificial lighting at night is one of the key anthropogenic changes associated with urbanised areas as well as some non-urban areas. Disruption to natural light/dark regimes can have considerable effects on the timing of different behaviours of birds, particularly during the breeding season. However, the effect of artificial lights on the timing of behaviours during winter has received relatively little attention, despite the fact that time partitioning of foraging can have implications for avian winter survival. In this study, we assess at a landscape scale during winter, whether birds arrive at feeding stations earlier in areas with increased levels of artificial lighting using data from a citizen science project. Arrival times of the ten most commonly recorded species were associated with a combination of the density of artificial lights, temperature, rainfall and urban land cover. We found no evidence that birds advance the onset of foraging in gardens with more artificial lights nearby; contrary to our prediction, birds generally arrived later into these areas. This is possibly a response to differences in food availability or predation risk in areas with more artificial lights. We conclude that artificial light at night may not be as important for driving the timing of foraging behaviour in winter as previously thought, but it remains to be seen whether this represents a missed opportunity to extend the foraging period or an adaptive response. 相似文献

This article examines gendered career paths in two feminizing and highly qualified professions. Quantitative data show that in medicine the profession is internally segregated by sex, as women tend to opt for the family friendly but clinically inferior specialty of general practice. In accountancy internal segregation by sex is considerably less evident but women fail to rise through organizational hierarchies. Qualitative interviews with qualified doctors and accountants suggest that sex discrimination is to some extent still an issue but that the major factor underlying these different gendered career trajectories is that women still retain the major responsibility for domestic work and caring. They also suggest that doctors have been able to exercise more control over their working hours than accountants and that even when accountants work part‐time, they work longer hours than contracted. Part‐time work is also seen as seriously career‐limiting. In our conclusions, we briefly examine the gender equality implications of these contrasting self‐regulated and market‐driven adaptations to occupational feminization. 相似文献

Self-disclosure is a crucial part of developing close interpersonal relationships during adolescence. In particular, sharing information with a greater depth of intimacy is thought to strengthen social bonds and thus support mental health. The current study investigated the value for different depths of self-disclosures to close others (mothers and best friends) during adolescence and its association with mental health and well-being. Fifty-four girls (11.0–15.9 years) completed a forced-choice monetary paradigm to assess value for self-disclosures and questionnaires on mental health. Participants significantly valued (i.e., forfeited monetary reward) for disclosures to both mothers and best friends, although intimate disclosures were more “costly” than superficial disclosures. Greater value for intimate self-disclosures to mothers was also associated with better mental health and well-being. 相似文献

A new variational Bayesian (VB) algorithm, split and eliminate VB (SEVB), for modeling data via a Gaussian mixture model (GMM) is developed. This new algorithm makes use of component splitting in a way that is more appropriate for analyzing a large number of highly heterogeneous spiky spatial patterns with weak prior information than existing VB-based approaches. SEVB is a highly computationally efficient approach to Bayesian inference and like any VB-based algorithm it can perform model selection and parameter value estimation simultaneously. A significant feature of our algorithm is that the fitted number of components is not limited by the initial proposal giving increased modeling flexibility. We introduce two types of split operation in addition to proposing a new goodness-of-fit measure for evaluating mixture models. We evaluate their usefulness through empirical studies. In addition, we illustrate the utility of our new approach in an application on modeling human mobility patterns. This application involves large volumes of highly heterogeneous spiky data; it is difficult to model this type of data well using the standard VB approach as it is too restrictive and lacking in the flexibility required. Empirical results suggest that our algorithm has also improved upon the goodness-of-fit that would have been achieved using the standard VB method, and that it is also more robust to various initialization settings. 相似文献

Many scientists believe that small experiments, guided by scientific intuition, are simpler and more efficient than design of experiments. This belief is strong and persists even in the face of data demonstrating that it is clearly wrong. In this paper, we present two powerful teaching examples illustrating the dangers of small experiments guided by scientific intuition. We describe two, simple, two‐dimensional spaces. These two spaces give rise to, and at the same time appear to generate supporting data for, scientific intuitions that are deeply flawed or wholly incorrect. We find these spaces useful in unfreezing scientific thinking and challenging the misplaced confidence in scientific intuition. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

ABSTRACTThe aims of this study were to compare the NZ Indices of Multiple Deprivation (IMD) with the NZDep index of socioeconomic deprivation in terms of their: (1) theoretical and methodological approaches; (2) use of small areas; (3) rankings of small areas; and (4) relationships with various health and social outcomes. Literature sources were reviewed for aim 1. The data sources for aims 2–4, all contained within Statistics New Zealand’s Integrated Data Infrastructure, were: (1) 2013 Census, (2) health data sets, (3) Police database, and (4) 2014 General Social Survey. Outcomes were smoking, mortality, respiratory disease, crime, self-assessed health status. Spearman’s rho was used as a measure of correlation. Deciles were treated as categorical in the stepwise logistic regressions. The key finding is that there is a range of theoretical and methodological differences between the indexes. Despite these differences, the indexes behave in a similar, but not identical, manner in their ranking of small areas and in their associations with health and social outcomes. In conclusion, for practical purposes for many applications the two indexes give similar results when analysing very large data sets, although there are some important caveats related to this conclusion for both large and small data sets. 相似文献

This article examines and reflects upon initial findings from a longitudinal study evaluating the experiences and views of students on professional social work programmes across four higher education institutes in the North West of England, on the BA and the MA routes. The paper focuses on one aspect of this study; the students' experience of assessment. In particular it examines how students experienced the process of learning, assessment, support and feedback, which was found to be in part shaped by previous educational experiences. The range of assessment methods previously experienced by students was diverse, some of which were more helpful than others in preparing them for their professional training. Lack of foundation subject knowledge presented a challenge to students on both courses, in particular for MA students who were being assessed at ‘M’ level. Unmet expectations of both the amount and type of support created anxiety, frustration and even anger for some. The ‘search for certainty’ led to anxiety amongst many first year students who believed that academics could facilitate the assessment process by providing ‘the answer’. This exploration of assessment reveals, we believe, a growing divide in the expectations of social work students and their educators. 相似文献

Abstract Permanency planning is a systematic, goal-directed and timely approach to case planning for children subject to child protection intervention aimed at promoting stability and continuity. The present paper reviews research into the area of permanency planning within the foster care system, with the aim of promoting research-informed policy and practice. Research published in both journals and books between 1998 and 2005 was reviewed. Exceptions to this were previously published seminal articles and texts that are theoretically and empirically important. The results of the present review indicate that permanency planning is theoretically informed by attachment theory and understandings of child development and identity formation. Decision making should be individualised, timely and culturally appropriate. Children themselves, their parents and carers all need to be involved in planning. Practitioners must be prepared to undertake extensive observation and assessment to serve the best interests of children when making permanency decisions. 相似文献
