Community gardens have been a part of modern American culture since the late 19th century. Participation in community gardening has ebbed and flowed in response to changing socioeconomic conditions, and thus the current economic recession has reheightened public interest. In a review of the scholarly literature from 1999 to 2010, rigorous quantitative research studies on the effects of community gardens are found to be sparse; however, a larger body of qualitative data is available. Eleven themes related to the purposes, benefits of, and motivations for participating in community gardens are identified. Community gardens can serve as an effective tool for community-based practitioners in carrying out their roles within the arenas of organizing, development, and change.  相似文献

This article examines the experiences of female migrants from Sub-Saharan Africa aiming to reach Europe via Morocco. The article argues that European immigration policies and policies of co-operation with neighbouring countries on the other side of the Mediterranean, have increased the sources of insecurity for migrants attempting to reach Europe, and shows how these insecurities are gendered.  相似文献

Intergenerational relations and reproductive behavior in Taiwan   总被引:1,自引:0,他引:1  
The character of intergenerational relationships between parents and their adult unmarried children in Taiwan is consistently and systematically related to the later reproductive behavior of the children after they marry. The greater the extent to which the adult unmarried children are exposed to nonfamilial relationships and contexts in school, at work, in the use of wages, in marriage decisions, and in first place of residence after marriage, the fewer children they will have and want and the greater the likelihood that they will begin contraception for spacing rather than for limiting their number. These relationships are consistent with theories about the transformation of familial relationships and reproductive patterns in the course of development.  相似文献

This paper uses longitudinal data for 1962–1977 to examine the relationship of husband’s income to 1962 expected fertility, to final parity, and to the discrepancy between initial expectations and final parity, separately for four groups of women who in 1962 either had just given birth to a first, second, or fourth child or had just been married. Although economic reasons frequently were cited in 1977 for downward revisions in family size goals, husband’s income was not positively related to fertility in three of the four parity groups. For the merged sample, excluding women with unwanted births, husband’s income showed a small positive relationship to completed fertility.  相似文献

The changing American family   总被引:1,自引:0,他引:1  
This Bulletin documents recent changes in American family patterns resulting both from longterm trends in urbanization, industrialization, and economic growth and the disruption of the Great Depression and World War 2, as well as changed attitudes toward marriage, parenthood, divorce, and the roles of women. Following a postwar boom in the 1950s and 1960s, marriage rates have now fallen to levels observed in the early 20th century. Since 1970, the number of unmarried couples living together has more than tripled to 1.9 million in 1983. The divorce rate has now stabilized after more than doubling since 1960, but at the current level, 1/2 of all recent marriages will end in divorce. Most divorced persons remarry fairly quickly, often creating complex families of "step-relatives." With 19% of households with minor children now headed by a women with no husband present, up to 1/2 of all children will live for sometime in a fatherless family before age 18. Over 1/2 of all married women, including 49% of married mothers of preschool children, now hold a paid job outside the home. Working wives boost a family's income by an average 40% but still are expected to shoulder most responsiblility for home and childcare. White women now in their 20s say they expect to have an average of 2 children, but are delaying childbearing to such an extent that 29% could end up childless. Most of the elderly live on their own but usually near children whom they see frequently. Despite changes in traditional family patterns, Americans consistently report that a happy marriage and good family are the most important aspects of life. And though most Americans now live with few or no family members, they maintain active contact with a large network of family.  相似文献

直线型再制造供应链决策结构的效率分析   总被引:37,自引:3,他引:37       下载免费PDF全文
将直线型再制造供应链分为5种不同的决策结构,研究了该供应链在不同决策结构下的收益以及与集成式"超组织"结构相比的效率损失.结果表明:回收物品的潜在期望收益是回收行为的驱动因素;销售商对生产商批发价的决定权越大,该决策结构就越有效,效率损失也越小;收益分享是实现逆供应链成员"双赢"目的的有效策略.  相似文献
