ABSTRACT

This paper examines the relationship between fossil fuels and food security and makes recommendations for community organizers. During the 20th century, North America's food system grew critically dependent on oil and natural gas for production, processing, and transportation. The authors argue that numerous petroleum-related factors including supply problems, increasing global demand, and geopolitical tensions may now threaten food security. Various approaches to reducing fossil-fuel dependency and increasing local food production are explored. The authors conclude that community organizers can make important contributions to local food security, and they provide specific recommendations and resources for doing this.  相似文献

The recent international surge in private equity markets has been accompanied by growing interest in its nature and effects. Private equity involves investment in unquoted companies and includes both early stage venture capital and later stage buyouts. The latter, which have been particularly controversial, are our focus. This paper provides a review of the different theoretical approaches that have been deployed to understand this phenomenon. Thereafter, the findings of a large cross section of empirical studies within a range of different national settings are compared and contrasted. Finally, existing themes emerging from – and gaps in – the existing literature and likely future directions are summarized.  相似文献

Decision theory, coupled with a hierarchically arranged questionnaire format, is discussed as a possible approach to the prediction of birth planning decisions. The empirical success of the scheme is examined in terms of interrelating attitudes, behavioral intention, desired family size, and birth planning behavior.This project was supported by Research Grant HD-07225-01A1 from the National Institute of Child Health and Human Development Center for Population Research, by NICHD Center Grant HD-09397-01 to the Center for Studies in Demography and Ecology, University of Washington, and by the University of Washington Graduate School Research Projects Fund, from the Public Health Service Biomedical Research Support Grants, Grant #RR07096.

We used capture-recapture methods to estimate bird species richness from mist-net and point-count data from a study area in Campeche, Mexico. We estimated species richness separately for each survey technique for two habitats, forest and pasture, in six sampling periods. We then estimated richness based on species' detections by either technique, and estimated the proportion of species detected by each technique that are not part of the population sampled by the other technique. No consistent differences existed between richness estimates from count data and from capture data in the two habitats. In some sampling periods, over 50% of the richness estimate from one survey technique may be species that are not sampled by the other technique, suggesting that one technique may not be adequate to estimate total species richness and that comparing estimates from areas sampled by different techniques may not be valid.  相似文献

Rural communities and well‐being: a good place to grow up?   总被引:1,自引:0,他引:1  
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

The Family Interaction Test is a narrative projective method designed to elicit children's perceptions of family life and patterns of interaction by way of stories around particular themes and events. Drawing on a post-modern interpretive approach, the paper proposes that traditional psychometric research methodologies underpinned by the logico-empirical paradigm are inappropriate in the study of narrative meaning. It is argued that practitioners, rather than seeing themselves as separate from the story teller and thus objectifying the ‘true’ meaning of the narratives, can instead enter into a discourse with the story teller as a way of testing hypotheses and thus establish the verisimilitude of story meanings. The results of a preliminary clinical study using this methodology with the Family Interaction Test are presented and discussed.  相似文献

Motherhood negatively affects female employment in majority populations across Europe. Although employment levels are particularly low among women of migrant origin, little is known about the motherhood–employment link in migrant populations. This paper investigates whether family formation differentially affects the labour market position of migrant women and their descendants compared to natives. Using longitudinal microdata from the Belgian social security registers, 12,167 women are followed from 12 months before until 48 months after the birth of their first child for the period 1999–2010. Levels of activity (versus inactivity), employment (versus unemployment) and full-time employment (versus part-time employment) are compared between natives and first- and second-generation women of Southern European, Eastern European, Turkish and Moroccan origin. We find that activity and employment levels decrease to a larger extent following the transition to parenthood among women of migrant origin than among natives. With respect to activity levels, differences between second-generation women and natives are largely explained by socio-demographic and pre-birth job characteristics, while differences between first-generation women and natives are not, suggesting that other factors such as tied migration patterns determine labour market attachment among first-generation mothers. With respect to employment levels, unemployment is increasing more among women of migrant origin of both generations than among natives, also when controlling for background characteristics, which signals differential access to stable job positions as well as to family policies. In sum, the results draw attention to the challenge that parenthood creates for mothers of migrant origin in terms of retaining and gaining employment, but also to the role of labour market entry and early career positions.  相似文献

This paper presents findings of an anthropological study among pregnant adolescents in Cape Town, South Africa. The inquiry focuses on the sexual dynamics within adolescent relationships. The study reveals widespread male coercion and violence within sexual relationships. Informants describe assault as a regular feature of their relationships. In South Africa, power relations between men and women are commonly manifested as and imposed through sexual violence and assault. Men use physical assault to force sexual contact, beating their female partners if they refuse to have sex, are suspected of sexual infidelity, or are found to be using contraceptives. Moreover, women experience abuse such as gang rape. Yet, health promotion interventions fail to acknowledge sexual encounters as instances in which unequal power relations between men and women are expressed. It is these power relations which determine women's ability or inability to protect themselves against sexually transmitted disease, pregnancy, and unwelcome sexual acts. This study underlines the need to consider gender power issues in the design and impact assessment of HIV/AIDS and reproductive health interventions and in challenging male violence.  相似文献
