Recognizing the inherent pressures on farm families and farmland, USDA has been developing policies and programs that simultaneously attempt to retain existing farm families on the landscape, recruit new farmers, and create lasting economic opportunities rooted in agriculture. In this article we argue that to date there has been an overemphasis on economic and structural approaches and a systematic discounting of the way individual farmer and farm household motivations can differ as they relate to the farm household life cycle, enterprise growth, adaptation, and reproduction. We use a sociological lens to qualitatively and quantitatively examine the social differences between multigeneration and first‐generation farmers at the rural‐urban interface by exploring how economic and noneconomic values influence succession plans and enterprise structure. We find that the answers to these questions are complex, layered, and not static, as farm households cycle through the life course. We describe how the differences between young and old multigeneration and first‐generation farmers can influence the structure of agriculture at the rural‐urban interface, and conclude with some practical policy recommendations. 相似文献

This study examined both mothers’ and fathers’ parenting (positive and negative) and adolescents’ personal characteristics (religiosity, social initiative, aggression, depression) in relation to perceived deviant peer association for European American and Latino adolescents. Using structural equation modeling, adolescents’ reports of positive or negative mothering and fathering were found to be related to adolescents’ personal characteristics, and these characteristics were, in turn, related to perceived deviant peer association. Ethnic differences in means were found in both parenting and outcome variables, with European American adolescents reporting higher levels of positive parenting and social initiative, and lower levels of perceived deviant peer association than Latino adolescents. Despite these mean differences, no ethnic differences were found in the overall measurement or structural model, suggesting that this process functions similarly for these two ethnic groups. 相似文献

This paper is part of a long-term investigation known as the Mormon Historical Demography Project. It examines the capability of a simulation model, originally proposed by John Bongaarts (1976), to fit the natural fertility pattern which characterized the mid-nineteenth century Mormon population. Application of this model permits estimates to be made of the historical timing and age-incidence of fertility limitation. A sensitivity analysis of the model’s parameters demonstrates that simple changes in the model’s proximate determinants of fertility, excluding contraceptive practices, would be insufficientto account for later transition effects. Thus the results successfully capture the dynamics underlying the Mormon natural fertility pattern as well as offer a framework for future modeling of the transition away from natural fertility. 相似文献

The effects of husband'spotential andrelative incomes on completed fertility, as well as their effects on certain parity progression probabilities, are examined within samples of Anglos, Blacks and Mexican Americans. Relationships are estimated using data from the one-percent 1960 and 1970 U.S. Public Use Samples. The results reveal different patterns of relationship by ethnicity between the measures of income and the measures of fertility. The effects on completed fertility of the income measures are positive for Anglos and negative for Blacks, while in the case of Mexican Americans the effect ofpotential income is negative and that ofrelative income is positive. Income effects on the parity progression probabilities are similar in pattern to those from the analyses using completed fertility, although somewhat different patterns tend to appear at different birth orders, especially among Anglos. 相似文献

Undocumented Mexican immigrants and the earnings of other workers in the United States 总被引:4,自引:0,他引:4
This article examines the effects of undocumented Mexican immigrants on the earnings of other workers in geographical labor markets in the Southwest. The number of undocumented Mexicans included in the 1980 census in southwestern SMSAs is estimated. We then estimate the parameters of three specifications of a generalized Leontief production function with various demographic groups as substitutable factors. The statistically significant effects of undocumented Mexicans on the earnings of other groups are positive, but of slight magnitude. Legal immigrants' effects on native white earnings, however, are small and negative. The results are consistent with the possibility that undocumented Mexican immigrants' jobs complement those of other workers. The implications for public policy concerns about the effects of illegal Mexican immigration are discussed. 相似文献

This essay examines the consequences of major social, demographic and economic trends in the United States since World War
II. These include rising women’s employment, the ‘Baby Boom’, the outlines of the so-called ‘new’ immigration, the increasing
racial and ethnic diversity deriving from that immigration, the economic contexts in which recent US immigration has occurred,
and recent technologically-induced features of global work flows that will condition immigration’s future reception and effects.
Women’s wartime work experiences, together with their economic opportunities in the ensuing decades, boosted married women’s
autonomy and domestic leverage. Rising economic prosperity encouraged marriage and family formation even as growing employment
among married women of childbearing age made having and taking care of large families more difficult. World War II also spawned
the expansion of migration to the United States, which in turn converted the country from a largely biracial society with
a sizable white majority and a small black minority into a multiracial, multiethnic society with greater racial and ethnic
boundary crossing and increasingly blurred colour lines. A major issue is whether currently changing economic conditions and
social institutions will support and strengthen such tendencies or instead weaken them. Without robust job growth, the demographic
legacy of the baby boom, which now involves ever-rising numbers of retired people, will be more difficult to support, especially
given the country’s current fiscal deficits. Greater earnings inequality and weak job growth may also poison the climate for
further immigration to the US, thus diminishing the chance that newcomers can continue contributing to the dissolution of
fault lines among racial-ethnic groups and to the resolution of periodic labour shortages. 相似文献
