Wild foods may offer unique benefits to households afflicted by AIDS, providing a nutritious and freely available food source at minimal labour and financial costs. This article presents the results of food security assessments in two rural South African sites. Detailed household dietary recalls from 227 households, combined with qualitative work, explored the association of household AIDS proxies (recent morbidity, mortality and orphan fostering) with household food security and dietary composition. The study found that AIDS-proxy households were significantly more food insecure, and households fostering orphans were both poorer and more food insecure. Wild foods were evident in 40.3% of the 48 h recalls, with significantly greater likelihood of use in households with fostering paternal orphans, and/or with at least one AIDS proxy. Only paternal orphans were significantly associated with likelihood of using wild foods when controlling for household socio-economic status. Qualitative data suggests that households afflicted by AIDS might curtail their use of wild foods due to household labour shortages and stigma. This is unfortunate, as regressions indicate that households using wild foods may be more economically resilient. This may be particularly important for households registering AIDS proxies, due to a demonstrated negative correlation between accumulated household AIDS proxies and household income.  相似文献

For the past decade and a half a concerted effort has been undertaken to determine whether policy interventions in residential location can solve the problems of inner-city poverty and racial concentration. Studies based on data from the Gautreaux litigation and the U.S. Department of Housing and Urban Development (HUD)-sponsored Moving to Opportunity (MTO) program have provided an overall optimistic interpretation of the possibilities of improving inner-city lives via mobility vouchers and counseling. A reanalysis of the data from the MTO program, focusing specifically on African American households, suggests greater caution in the interpretation of the findings from either Gautreaux or the MTO program. No statistically significant difference exists between the percentage of poor or the percentage of African Americans in the current neighborhoods between MTO and Section 8 experimental groups. In some cases, there is no statistically significant difference between those who move with a voucher and those who move without any assistance at all. Although there is some evidence that MTO programs have brought specific gains for individual families, claims for the MTO program as a whole need to be treated with a great deal more caution than they have been to date.  相似文献

Two overseas survey-based scales measuring perceived quality of neighbourhood were adapted and replicated in a New Zealand context. An Italian study (Bonaiuto, Fornara, and Bonnes. (2003). Landscape and Urban Planning, 65, 41–52) measuring Perceived Residential Environmental Quality (PREQ) and an American study (Carp and Carp. (1982). Journal of Environmental Psychology, 2, 295–312) using the Perceived Environmental Quality Indices (PEQI) were applied to a sample of Auckland residents, separated into low, medium, and high population density areas. The surveys measured attitudes towards subjects such as noise, neighbours, accessibility, green areas, welfare services, recreational services, safety, maintenance, environmental health, transport services, and characteristics of an ideal neighbourhood, and were completed by 369 respondents. Primary analyses examined differences in perception across the three density groups. The factor structures of both scales were replicated with the Auckland sample, and differences across densities were found for subscales of the PREQ. The results are discussed in relation to the cross-cultural similarities of perceived environmental quality, and the concept that environmental satisfaction is based on balancing aspects of the residential environment is proposed. This research was conducted for the Foundation for Research, Science, and Technology under contract OPSX401.  相似文献

Is the Study of Happiness a Worthy Scientific Pursuit?   总被引:1,自引:1,他引:0  
This paper critiques the view that the study of happiness is not a worthy scientific pursuit. The happiness set point and hedonic treadmill theories denote the complexity of increasing happiness levels due to genetic limitations and adaptation, however, there is mounting evidence to suggest that with the use of appropriate measures and specific interventions aimed at fostering strengths and virtues, happiness can be increased. Furthermore, the benefits of investigating methods for increasing happiness include improvements in physical, psychological and social health and well-being. It is concluded that approaching human needs from a top down or holistic standpoint where individuals can use their strengths to overcome life’s challenges, is beneficial to health and well-being. Hence, the study of happiness is a worthy scientific pursuit.  相似文献

This paper characterizes vulnerable workers in Canada and the federal jurisdiction, based upon characteristics such as employment status, demographic characteristics, and job characteristics, and identifies areas in which labour standards may have a role. Based on this analysis, the paper evaluates the potential for labour standards to address economic vulnerability, focusing on labour standards policies aimed at wages and benefits, hours, and employment arrangements. In addition, the analysis considers the extent to which labour standards are likely to reach vulnerable workers. The results suggest several potential roles for labour standards and highlights policy implications.

In a recent article (Frisbie. Forbes. and Pullum 1996) we documented racial/ethnic differences in birth outcomes according to a more fine-grained classification than has typically been employed in the demographic literature. In his commentary, van der Veen focuses on the measurement of one of the dimensions of that classification, maturity of the infant. as proxied by the fetal growth ratio. The crux of the critique is easily seen in van der Veen's statement that “all of my disagreements with Frisbie et al. 's method arise from their particular use of a postnatal standard for the assessment of intrauterine growth.” Our critic misunderstands our objective: He fails to realize our interest in birth outcome, not pregnancy process, and does not perceive that our intent was to extend the research extant in both the demographic and public-health literatures in which patently postnatal (i.e., ex utero) measures are taken as outcomes interesting in their own right and/or as risk factors for infant mortality and infant and childhood morbidity. Specifically, he does recognize that we purposefully expanded our focus to include moderately compromised births to determine if they were at higher risk than the normal births with whom they are conventionally categorized. Our discussion draws on research cited in the original article, on studies cited by our critic, and on a few more recent investigations. Although we have never argued that ours is the only, or even the best, approach in all cases, we try to clarify the rationale for, and adduce additional empirical evidence of, the utility of the method we used.  相似文献

We investigate the extent and implications of cohabitation and marriage among U.S. welfare recipients. An analysis of four data sets (the Current Population Survey, the National Survey of Families and Households, the Panel Study of Income Dynamics, and the National Longitudinal Survey of Youth) shows significant numbers of cohabitors among recipients of AFDC. An even more surprising finding is the large number of married women on welfare. We also report the results of a telephone survey of state AFDC agencies conducted to determine state rules governing cohabitation and marriage. The survey results indicate that, in a number of respects, AFDC rules encourage cohabitation. Finally, we conduct an analysis of the impact of AFDC rules on cohabitation, marriage, and single motherhood and find weak evidence in support of incentives to cohabit.  相似文献

Family membership and household composition do not always coincide. Joint legal custody after divorce formalizes the relationship between fathers and children who live apart. Policymakers hope that explicit acknowledgment of nonresident fathers’ rights and responsibilities will increase their involvement with their children. I use prospective data from the National Survey of Families and Households to examine the association between joint legal custody and two aspects of nonresident fathers’ contributions to their children—the frequency of visits between fathers and children and child-support payments. The analysis examines approximately 160 families in which parents divorced between interviews conducted for Wave 1 (1987–1988) and Wave 2 (1992–1994) of the survey. I investigate the effects of joint legal custody holding constant physical custody or placement by restricting the analysis to children who live with their mothers most of the year. Controlling for socioeconomic status and the quality of family relationships before separation, fathers with joint legal custody see their children more frequently and have more overnight visits than do other fathers. The positive effect of joint legal custody on frequency of visits persists once unobserved differences among families are taken into account. Although fathers with joint legal custody pay more child support than those without joint legal custody, this difference lacks statistical significance when other family characteristics are taken into account. These findings support the view that joint legal custody may encourage some aspects of paternal involvement after divorce.  相似文献
