Informal Food Production in the Enlarged European Union 总被引:1,自引:0,他引:1
How widespread is the production of food in old and new member states of the European Union and what is the social meaning or logic of such activities? We show that growing food is (a) more widespread in former communist countries than in traditional market economies and (b) is predominantly a hobby or recreational activity in affluent countries, but a coping strategy in reaction to experienced difficulties in making ends meet in poorer nations, and especially so in the former communist countries. 相似文献

The paper presents a model of a non-resident father’s child support and contact with his child, which combines the public
good treatment of “child quality” with “trade” in father–child contact time in a setting of non-cooperative interaction. It
predicts that father’s income and mother’s non-labour income should have exactly the same effect on the frequency of father–child
contact if he chooses to make lump sum payments to the mother. If he does not or there is a binding child support payment
order, they have effects opposite in direction. A higher binding support order reduces father–child contact but may well raise
“child quality”.

The claim that multiple partner fertility may pose a risk of adverse outcomes for children has not been tested. We test this argument using a sample of 4,027 resident fathers and children from the Fragile Families and Child Well‐being Survey by examining the pathways through which fathers' multipartnered fertility is associated with children's externalizing behaviors and physical health status at 36 months. Path analyses indicate that multiple partner fertility exerted both a significant direct and indirect effect through paternal depression to influence children's externalizing behaviors. Fathers' multiple partner fertility also exerted a significant indirect effect through one mediator—father involvement—to influence children's physical health. This evidence suggests that the disruptions brought about by multipartnered fertility are important for understanding child well‐being. 相似文献

Few programs to enhance fathers' engagement with children have been systematically evaluated, especially for low‐income minority populations. In this study, 289 couples from primarily low‐income Mexican American and European American families were randomly assigned to one of three conditions and followed for 18 months: 16‐week groups for fathers, 16‐week groups for couples, or a 1‐time informational meeting. Compared with families in the low‐dose comparison condition, intervention families showed positive effects on fathers' engagement with their children, couple relationship quality, and children's problem behaviors. Participants in couples' groups showed more consistent, longer term positive effects than those in fathers‐only groups. Intervention effects were similar across family structures, income levels, and ethnicities. Implications of the results for current family policy debates are discussed. 相似文献

The contribution of parental involvement in the parent–teacher association (PTA) to schoolchildren's performance is an issue for evaluation research. To resolve the issue, it is reasonable to differentiate people who benefit and others who do not benefit from the involvement. Such differentiation relied on survey data from 289 pairs of Hong Kong Chinese parents and their children between Grade 4 and Grade 9. It revealed that only 28.8% of the parent–child pairs had their child performance benefiting from the help of parent–teacher associations (in terms of a standardized effect of .2). Factors predictive of this minority subgroup were the child's grade and having a single parent. These factors tend to identify the need for help from parent–teacher associations, which can be a consideration for planning effective help from the associations. 相似文献

We present results from a new study of the effects of migration to the USA on the well-being of transnational families in high emigration communities within Mexico. Our survey measured the well-being of family members in a variety of domains: economic, health, education, and child development for a representative sample drawn from high migration municipalities. Compared to those with no recent emigrants to the USA, Mexican households sending non-caregivers to the USA appear to gain economically without contributing to problems faced by children. However, when family caregivers migrate to the USA, the remaining members in Mexico struggle to meet the family's needs and children are more vulnerable to educational, emotional, and health problems. Children in households where a caregiver migrated were more likely to have frequent illnesses (10% vs. 3%, p<0.0001), chronic illness (7% vs. 3%, p=0.011), emotional problems (10% vs. 4%, p=0.006), and behavioral problems (17% vs. 10%, p=0.018) compared with children in households where the migrant was not a caregiver. Research, policy, and program implications of these findings are discussed. 相似文献

代际支持对老年人主观幸福感的影响--基于年龄组的差异性分析 总被引:1,自引:0,他引:1
本文从年龄组差异的角度分析了代际支持对老年人心理健康的影响。研究发现,在控制了客观健康状况等变量后,老年人的心理健康水平并非随着年龄增长呈现出下降趋势。其次,接受代际支持和给予代际支持都对老年人心理健康有着显著的促进作用。第三,对于不同年龄组来说,代际支持对老年人心理健康产生的效果既有共同点也存在着差异。相似之处在于充足的经济支持对65-74岁、75-84岁和85岁及以上这三个年龄组老人的心理健康都是有利的。然而,更突出的是这三个年龄组之间的相异点:对于65-74岁这一组别而言,老人与子女之间的经济交换最为频繁。这种经济上的互惠提升了老人的积极情绪、抑制了消极情绪的产生。就75-84岁的老年人来说,子女在日常照料的作用表现的十分显著。和子女共同居住、在生病时由子女照料的老人表现出更少的消极情绪。至于85岁以上的高龄老人,得到充足的情感支持对于提升主观幸福感的作用更为显著;最先和子女分享想法的老人有着更高的心理健康水平。因此就现实状况来看,当父母逐渐衰老,作为子女,应当更加关注对父母的日常照护和情感关怀。尤其是对于这些高龄老人,他们对子女的情感态度更为敏感;子女提供的充足的情感支持对其心理健康有着十分显著的促进作用。 相似文献

Experience of material hardship can adversely affect a family’s ability to make long-term investments in children’s development. We examine whether material hardship is associated with one indicator of such investments: participation in a tax-advantaged college savings plan (529 plan). Data for this study come from the SEED for Oklahoma Kids (SEED OK) experiment, an intervention that offers Child Development Accounts with financial incentives to encourage the accumulation of college savings for children from the time of their birth. Results show that material hardship is negatively associated with 529-plan participation, and this association varies by treatment status. At all levels of material hardship, treatment-group mothers are more likely to hold accounts than control-group mothers. These findings suggest that CDAs can be a useful policy tool to support families’ financial preparation for college. 相似文献

Debates in international forums and in mainstream media on the role, responsibility, liability, and response of ecclesiastical authorities of the Roman Catholic Church (RCC) toward clerical child sexual abuse (cCSA) fail to take into account the historical roots and awareness of the problem. Reports also fail to mention the historic organizational laws RCC developed over centuries. In contrast, RCC documents evidence that the Catholic Church not only carried century’s old history of cCSA, but also repeatedly condemned cCSA by successive papal authorities, organizational laws, and institutional management mechanisms. During the first millennium, however, church laws remained confined to the bookshelves and were not converted into appropriate management policies and infrastructural models. This was largely due to the absence of a central administrative organizational structure, which developed later in the 12th century, following the Second Council of Lateran (1139) when the Papacy asserted its authority to establish administrative control over the organizational church. It was only then that management policies started to be framed and institutional structures enacted to deal more appropriately with cCSA from the 14th to 20th centuries. Despite this, RCC developed a culture of secrecy using clandestine organizational management models and institutional laws prescribed in 1568, 1622, 1741, 1866, 1922, and 1962 which aimed to manage cCSA. The current study traces reported cCSA as far back as the first century and critically examines the organizational laws, and institutional policies developed by RCC to address clerical sexual misconduct up to the end of the 19th century. 相似文献

Using a grounded theory approach, this study evaluated narratives from a sample of 170 emancipated foster youth (66.5% female; 84.6% non-white) as they reflected on their experiences between the ages of 18 and 25 across three data waves. Corbin and Strauss’ (1990) three-phase coding process revealed five overarching themes: adult values and characteristics, nature of the transition process, material needs and resources, relationship concerns, and affective experiences. Although some elements of Arnett’s (2000) model of emerging adulthood were evident in this sample of emancipated foster youth, such as individualistic qualities and instability, other core features were rarely discussed, such as self-focus and optimism, or were expressed in unique ways, such as exploration and feeling in-between. There were significant age-related changes, but not gender differences, in youth’s discussion of varied themes. These findings suggest promising avenues for intervention during the sensitive period of developmental reorganization that characterizes the transition from adolescence to young adulthood. 相似文献
