Objectives. What were the determinants and patterns of naturalization in the first two decades of the 20th century? Low levels of citizenship acquisition among contemporary immigrants are frequently contrasted to the assumed rapid naturalization of prior European migrants, but in truth we know little about the earlier period. Historic data are well suited to investigate four explanations for naturalization: individuals' resources and skills; regulatory and bureaucratic barriers to citizenship; relative costs and benefits of citizenship; and the degree of political mobilization directed to immigrants. Methods. I use U.S. Census microfile data to run logistic regression models, and documentary material to examine the contours of immigrant naturalization in the early 20th century. Results. I find that while individual attributes matter, place of residence could be even more important; in 1900, where an immigrant lived influenced naturalization more than birthplace, ability to speak English, or literacy. Residence effects seem linked to a state's relative openness to immigration and local political mobilization. Over time, however, residence effects attenuate as the 1906 Naturalization Act and establishment of a federal naturalization bureaucracy appear to make citizenship patterns more uniform across the country. Conclusions. These findings suggest that historic and contemporary explanations of immigrants' naturalization should focus as much on the context of reception as the presumed quality of immigrants.  相似文献

A common problem in the provision of coordinated long‐term care is the separation of health and social care. The present government has been increasingly concerned with promoting convenient, user‐centred services and improving integration of health and social care. One arrangement that could contribute to this for some older service users is for health care staff to act as care managers, coordinating the provision of both health and social care. This paper presents the findings of a survey of arrangements in place in local authorities for health staff to work as care managers for older people. This was designed to provide details about the range and scope of care management activities undertaken by health care professionals. Key areas of enquiry included: which kinds of health care staff undertook care management and in what settings; how long the arrangements had been in place and how widely available they were; whether there was a distinction between the types of cases and care management processes undertaken by health care staff compared with their social service department counterparts; and what management and training arrangements were in place for the health care staff.  相似文献

A flock of starlings wheel overhead, thousands of birds rising, falling, turning as if of one mind. Birds move in flocks; fish in schools; insects in swarms. How do they do it? Can we study them to find quantitative answers or must we simply admire them? Andrea Cavagna and Irene Giardina do both.  相似文献

Relying on interviews with contingent workers in diverse jobs, this article explores the motivations underlying worker consent, in particular, workers' commitment to employers who did little to encourage it. Driven by the need to address the “spoiled identity” problem brought on by contingent employment, workers engaged in identity‐management strategies that included the following: defining a willingness to work hard rather than the job per se as determinative of personal value, asserting an alternative vocation as one's appropriate identity‐conferring occupation, and aligning with managers as a reference group. These strategies had the ideological effect of reaffirming a managerial ideology that hampered the ability to formulate a critique of existing employment relations. A much smaller group, made up of disillusioned day laborers with few illusions about middle‐class respectability, rejected identity‐management strategies and regarded their relationship with employers in the purely instrumental terms that the business press assumes would apply to all workers. The article concludes that cultural lag and the raw appeal of the notion of a caring employer may underlie the persistence of the accommodationist orientations displayed by most of these workers.  相似文献

We investigate an optimization problem for mixture experiments. We consider the case when a large number of ingredients are available but mixtures can contain only a few number of ingredients. These conditions are held in experiments for self assembling molecular systems. First, we introduce a concept of uniform coverage design specialized for the situation. Next, we propose to use the stepwise technique for estimating coefficients of third-order Scheffe model which describes a response surface. After that, we propose a method of adding new mixtures for a movement to an extremum region. By this method, additional mixtures of experiments are extremum points of current estimated model and points which lead to more accurate estimation of current model prediction. This methodology is studied numerically for a model constructed from real data.  相似文献

This paper addresses the processes underlying the dramatic shift in beliefs about women's work and family roles in the United States over the past two decades. Following Mason and Lu (1988) , we posited this shift to be a function of actual change in individual opinions, as well as changes in population membership that result from births and deaths. Using pooled cross‐sections from the General Social Surveys (1977 to 1996), we found that although demographic processes and microlevel attitude change are both important in understanding attitude trends, the contribution of cohort succession is substantially greater now than in the period that Mason and Lu examined. Multivariate analyses show that (a) the sex difference in attitudes is greater among recent cohorts, and (b) the strong association between education and attitudes that characterized earlier cohorts is significantly weaker among cohorts born after 1945.  相似文献

A comparison of the basic traits of American character in the 1950s and the 1970s suggests that the narcissism of the 1970s is continuous with the other-direction of the 1950s, except that the narcissist makes a virtue out of what the other-directed person saw as problematic. The narcissist accommodates himself more fully to a social structure that demands great personal flexibility. He thus adopts a fluid identity and personal role definitions. Suggestive evidence of such identity change is found in the self-help literature of 1940 to 1979.  相似文献
