This review documents the economic context within which American families lived in the 1990s. Despite nearly full employment and growing income and wealth for many Americans, problem areas included persistent racial gaps in economic well‐being, growing inequality, and declining wages for young men. Women showed stronger income growth than men in the decade, and 2‐earner households became increasingly associated with advantage. We review the consequences of these trends and of economic well‐being generally on 4 dimensions of family outcomes: family formation, divorce, marital quality, and child well‐being. Despite hypotheses suggesting that women's earnings might have different effects on family outcomes than men's earnings, generally the review supports the expectation that both men's and women's economic advantage is associated with more marriage, less divorce, more marital happiness, and greater child well‐being. Important issues regarding measurement, reciprocal relations between family structure and economic well‐being, and race and gender effects remain unresolved. 相似文献

This article delineates and assesses the evidence for four perspectives that have guided previous research on the relationship between wives’ economic resources and marital stability. Hypotheses from these perspectives were tested using event history methods and 1980–1997 panel data for 1,704 individuals from the Marital Instability Over the Life Course study. Both wives’ dollar income and wives’ percentage of total family income served as measures of wives’ economic resources. The association between wives’ percentage of income and divorce formed an inverted U‐shaped curve, with the odds of divorce being highest when wives contributed between approximately 40% and 50% of the total family income. When wives’ resources were measured in dollars, wives’ income showed a positive, linear association with the odds of divorce. These findings provide the strongest support for an equal dependence perspective, which argues that economic dependence and obligation influence marital stability. 相似文献

Urban green spaces, such as forest fragments, vacant lots, and community gardens, are increasingly highlighted as biodiversity refuges and are of growing interest to conservation. At the same time, the burgeoning urban garden movement partially seeks to ameliorate problems of food security. Arthropods link these two issues (conservation and food security) given their abundance, diversity, and role as providers of ecosystem services like pollination and pest control. Many previous studies of urban arthropods focused on a single taxon (e.g. order or family), and examined either local habitat drivers or effects of landscape characteristics. In contrast, we examined both local and landscape drivers of community patterns, and examined differences in abundance, richness, and trophic structure of arthropod communities in urban forest fragments, vacant lots, and community gardens. We sampled ground-foraging arthropods, collected data on 24 local habitat features (e.g., vegetation, ground cover, concrete), and examined land-cover types within 2 km of 12 study sites in Toledo, Ohio. We found that abundance and richness of urban arthropods differed by habitat type and that richness of ants and spiders, in particular, varied among lots, gardens, and forests. Several local and landscape factors correlated with changes in abundance, richness, and trophic composition of arthropods, and different factors were important for specific arthropod groups. Overwhelmingly, local factors were the predominant (80 % of interactions) driver of arthropods in this urban environment. These results indicate that park managers and gardeners alike may be able to manage forests and gardens to promote biodiversity of desired organisms and potentially improve ecosystem services within the urban landscape. 相似文献

Urban gardens may support bees by providing resources in otherwise resource-poor environments. However, it is unclear whether urban, backyard gardens with native plants will support more bees than gardens without native plants. We examined backyard gardens in northwestern Ohio to ask: 1) Does bee diversity, abundance, and community composition differ in backyard gardens with and without native plants? 2) What characteristics of backyard gardens and land cover in the surrounding landscape correlate with changes in the bee community? 3) Do bees in backyard gardens respond more strongly to local or landscape factors? We sampled bees with pan trapping, netting, and direct observation. We examined vegetation characteristics and land cover in 500 m, 1 km, and 2 km buffers surrounding each garden. Abundance of all bees, native bees, and cavity-nesting bees (but not ground-nesting bees) was greater in native plant gardens but only richness of cavity-nesting bees differed in gardens with and without native plants. Bee community composition differed in gardens with and without native plants. Overall, bee richness and abundance were positively correlated with local characteristics of backyard gardens, such as increased floral abundance, taller vegetation, more cover by woody plants, less cover by grass, and larger vegetable gardens. Differences in the amount of forest, open space, and wetlands surrounding gardens influenced abundance of cavity- and ground-nesting bees, but at different spatial scales. Thus, presence of native plants, and local and landscape characteristics might play important roles in maintaining bee diversity within urban areas. 相似文献

ABSTRACTTelephone-based interactive voice response (IVR) systems could be an effective tool for promotion of physical activity among older women. To test IVR feasibility, we enrolled 30 older women in a 10-week physical activity intervention designed around National Institute on Aging (NIA) Go4Life® educational materials with IVR coaching. Participants (mean age = 76 years) significantly increased physical activity by a mean 79 ± 116 (SD) minutes/week (p < .001). Participants reported that the Go4Life® materials, pedometer, and IVR coaching (70% reported easy technology) were useful tools for change. This pilot study demonstrates IVR acceptability as an evidence-based physical activity program for older women. 相似文献

How well can we track cohabitation using the SIPP? A consideration of direct and inferred measures 总被引:1,自引:0,他引:1
Cohabitation is an alternative to marriage and to living independently for an increasing number of Americans. Still, research that explores links between living arrangements and economic behavior is limited by a lack of data that explicitly identify cohabiting couples. To aid researchers in using the Survey of Income and Program Participation's (SIPP) rich data to explore cohabitation issues, we consider direct and inferred measures of cohabitation. We find, first, that the use of inferred definitions (relative to direct measures) in the SIPP is likely to yield higher cohabitation rates in the United States by incorrectly coding roommates as cohabitors. Second, the SIPP (whether by direct or inferred measures) counts a significantly larger number of cohabiting couples than the widely used Current Population Survey (CPS). Third, spells of cohabitation occur less frequently and last longer when a direct measure of cohabitation is used than when either of the two inferred measures of cohabitation is used; ours is the first article to reveal this result. 相似文献

From 1992 to 1994, Saturday Academy and the Oregon Graduate Institute of Science and Technology instituted the pilot phase of a long-term monitoring program called the Student Watershed Research Project (SWRP). The SWRP program was developed to create and maintain collaboration among eighth through twelfth grade teachers and students, scientists, businesses, governmental agencies, and community members which would couple environmental education with the collection of high quality, reproducible watershed health data.The original authors of this paper set out to evaluate the impacts of the SWRP program in terms of changes in educational attitudes of participants and collection of accurate data. Findings demonstrate that assuring accuracy of student collected data was challenging, that teachers and students benefited greatly from a hands-on research approach to science education, and that such an approach would be difficult without the support of a program like SWRP.The SWRP program is entering its seventh year in the Portland, Oregon and Vancouver, Washington metropolitan areas with approximately half of the pilot phase participants still involved. A Quality Assurance Project Plan has been developed to assure data accuracy. Evaluation student science education attitudes documents improved results on a yearly basis. 相似文献

The authors examine differences between mean, variance, and correlation parameter estimates derived from a full school-based sample and subsamples restricted by the provision of parental consent. A total of 1,607 students at 21 continuation high schools and 1,192 students at 3 traditional high schools completed a survey containing variables related to sociodemographics, drug use, mental health, and violence. The employment of a researcher-initiated home-telephone-call procedure substantially increased the parental response rate over a student-/school-assisted consent method. The subsamples restricted by the written consent criterion showed some small biases in estimates of sociodemographic variables but little or no biases on measures related to mental health, drug use, or violence measures. The augmentation of the written consent samples with verbally consented students reduced observed biases. 相似文献
