Marriage outside one's ethnic or racial group constitutes the ultimate test of assimilation. In this research, we offer a new test of theories of assimilation by examining the choice of marriage partners among Mexican Americans, several European immigrant groups, and natives. Data from the 1880 to 1990 Integrated Public Use Microdata Samples (IPUMS) are employed, augmented by additional identification procedures developed for the Hispanic population. Assimilation measured by intermarriage rates varies by ethnic origin with striking affinity in historical patterns for Italians and Mexicans. Density and location of ethnic settlement, sex ratios, and generational mix played a role. Continued immigration marks certain groups, such as Mexicans, as structurally distinct. 相似文献

This research employs United States census data from 1880 to 1970 to assess the influence of ethnicity and generation on the family structure of Mexican, Irish, Swedish, Italian, Polish, and native white children. Using evidence for three generations, it tests two theories, linear assimilation and segmented assimilation. Assimilation theory makes no special claims for ethnic effects, but segmented assimilation proposes that ethnicity influences the incorporation of immigrant-origin children into American society. We find few consistent ethnic effects on the probability of family type. Our principal finding is that migration itself, common to all groups, has similar consequences for all; these are revealed in generational changes in family structure. The historical periods of open immigration do differ from the contemporary period, which implies that immigration policy affects family structure. The results disconfirm segmented assimilation theory's emphasis on ethnicity in family structure, and confirm aspects of linear assimilation theory. They point to the salience of structural factors resulting from the migration process and policy, rather than ethnicity, in the evolution of family form among immigrant-origin persons. 相似文献

Abstract Suburbs are becoming increasingly diverse as they continue to comprise larger portions of the metropolitan population and employment. Former perceptions of suburban uniformity are being eroded by the variance in form and function that now characterizes them. This article analyzes data collected on 3,567 non‐central‐city, incorporated, metropolitan places in the United States along the dimensions of population, place, economy, and government. Specifically, a hierarchical clustering procedure, combined with discriminant analysis, identifies 10 distinct types of suburbs in the data. Level, composition, and combinations of wealth, employment, and race drive the distinctions among suburban clusters, many of which do not fit our traditional characterizations of suburbia. In fact, only about half of all the suburbs considered are strongly characterized by these traditional traits, and these suburbs contain less than one out of every three residents considered in the analysis. 相似文献

ABSTRACTAlthough the mortgage interest deduction enjoys broad public support, critics argue that the policy disproportionately benefits wealthy households, fails to expand homeownership opportunities to households on the margins, and costs the federal government an extraordinary amount of money in foregone tax revenue. Drawing on data collected through an online experiment, this analysis tests the sensitivity of public support to these critiques. The findings reveal that support for the mortgage interest deduction declines when respondents are presented with information about the cost, effectiveness, or distribution of benefits associated with the deduction. Support among renters is more sensitive to framing effects than that among homeowners. Republicans are less sensitive to framing effects than Democrats when the deduction is framed as distributing benefits unequally, but more sensitive to these effects when the issue is framed as costly. However, all groups register their lowest level of support when told that the mortgage interest deduction is not an effective tool for expanding ownership opportunities. 相似文献

Purpose
The current study seeks to examine the relationship between low self-control and cigarette smoking, alcohol use, and marijuana use in adolescence and adulthood using behavioral genetic methodology.Methods
Using a subsample of twin pairs from the National Longitudinal Study of Adolescent Health (Add Health), the current study estimates the genetic and environmental overlap between low self-control and substance use (or problems associated with substance use) across four waves of data collection.Results
The overall pattern of results suggests that genetic factors explain a moderate proportion of the variance in low self-control and substance use in both adolescence and adulthood. Furthermore, bivariate genetic analyses reveal that the correlation between low self-control and substance use is due, for the most part, to common genetic and nonshared environmental factors.Conclusions
The current study adds to a growing body of biosocial research on self-control and its relationship to criminal and analogous behaviors. The implications of our findings for the general theory of crime are discussed. 相似文献218.

Contemporary Australian public policy has come to rely increasingly on technical reports produced by commercial consultants in contrast to the traditional approach, which employed disinterested public servants to generate the specialist information required to inform decision makers. This approach is fraught with problems, not least the fact that ‘hired guns’ have strong incentives to create the ‘answers’ sought by their employers. By way of a ‘cautionary tale’, this paper examines the empirical evidence adduced in favour of radical amalgamation of Tasmanian local authorities in Local Government Structural Reform in Tasmania, produced by Deloitte Access Economics (DAE) (2011), and commissioned by the Property Council of Tasmania. In particular, the paper provides a critical analysis of the econometric modelling undertaken in the DAE (2011) Report. We find that if the DAE model is re‐estimated – employing alternative functional forms – then the empirical evidence in support of Tasmania council merges evaporates. 相似文献

We estimate the impact of business formalisation using nationally representative panel data on businesses in Vietnam. Our data allows us to observe businesses for two surveys prior to obtaining a licence and hence to control for differential trends before formalisation. We find that obtaining a licence is not associated with an increase in profits or other business outcomes such as revenue, expenses, and employment once we control for differential trends. Controlling for trends is crucial, as estimates that ignore trends consistently find a larger positive association between becoming licensed and business performance. Our results suggest that inducing more businesses to register is unlikely to bring about large-scale changes for these businesses. 相似文献

Research on the motives of those who engage in small group political violence typically takes a qualitative or quantitative form. I argue that researchers should seek to understand why people engage in small group political violence, and that the best way to achieve such understanding is to employ both. The advantages of this approach are discussed in this paper, as is the importance of recognizing that the activities of all actors in any given violent location, including state actors, should be accounted for in research. 相似文献
