Geographic Mobility and Spatial Assimilation among U. S. Latino Immigrants1

Although the spatial assimilation of immigrants to the United States has important implications for social theory and social policy, few studies have explored the atterns and determinants of interneighborhood geographic mobility that lead to immigrants’residential proximity to the white, non‐Hispanic majority. We explore this issue by merging data from three different sources ‐ the Latino National Political Survey, the Panel Study of Income Dynamics, and tract‐level census data ‐ to begin unraveling causal relationships among indicators of socioeconomic, social, cultural, segmented, and spatial assimilation. Our longitudinal analysis of 700 Mexican, Puerto Rican, and Cuban immigrants followed from 1990 to 1995 finds broad support for hypotheses derived from the classical account of minority assimilation. High income, English language use, and embeddedness in Anglo social contexts increase Latino immigrants’geographic mobility into Anglo neighborhoods. U. S. citizenship and years spent in the United Stares are ppsidvely associated with geographic mobility into more Anglo neighbor oods, and coethnic contact is inversely associated with this form of mobility, but these associations operate largely through other redictors. Prior experiences of ethnic discrimination increase and residence in public housing decreases the likelihood that Latino immigrants will move from their origin neighborhoods, while residing in metropolitan areas with large Latino populations leads to geographic moves into “less Anglo” census tracts.     

Evaluation of changes to family income supplement

The work described in this paper was commissioned by the DHSS policy branch responsible for family benefits. The problem is rather more specific than those addressed by the studies described in the paper by Holdaway and Partridge. It does however parallel at least one of the observations made there. The study started out with a relatively broad brief but was constrained by events to concentrate on one particular problem, namely forecasting the cost and caseload of Family Income Supplement.     

Optimal design of a post office

A mathematical model which describes the postal operations is discussed in this paper. This paper is confined to the problems which arise within a post office in mail sorting and classifying operations.     

How manufacturing industries connect cities across the world: extending research on ‘multiple globalizations’

In this article, I concentrate on a macro‐level analysis of inter‐urban linkages in a ‘world city network’. Empirical research on the formation of a world city network has mostly concentrated on global service providers. Yet, globally operating manufacturing firms also choose distinct urban regions throughout the world as locational anchoring points. In this article, using social network analysis, I present the first global‐scale analysis of how manufacturing firms connected cities across the world (in 2010). To detect the differing ‘sectoral profiles’ and nodal centralities of cities functioning as geographical hubs of transnational production networks, it is necessary to analyse the network structure of distinct industrial subsectors within the global urban system. The data collected for analysis cover 120 top global firms from three manufacturing subsectors, of which two are analysed in more detail than the third. I then compare the nodal centralities of cities included in these subsectors' global networks with the GaWC research on the producer services sector that has been at the centre of previous analyses of the world city network. The comparison reveals the cities' differing positioning within ‘multiple globalizations’. The aim of the article is to extend research on world city networks.     

Identifying the needs of LGBTQ immigrants and refugees in Southern Arizona

This article reports on the results of a needs assessment conducted for lesbian, gay, bisexual, transgender, and queer (LGBTQ) immigrants, asylees, refugees, and their allies in Southern Arizona, and it is the first study of its kind in the United States. Utilizing interview data collected with migrants, allies, and service providers in Tucson, Arizona, this article presents findings on the quality of service provision provided to this very underserved community pertaining to health care, housing, and legal services. The assessment shows that no services are provided specifically for LGBTQ migrants, and most LGBTQ migrants turn to family and friends when they have needs. The most significant result of this study pertains to the lack of cultural competence and an overall deficiency in terms of cultural awareness when it comes to the specific needs of LGBTQ migrants.     

Community Perceptions of Industrial Risks Before and After a Toxic Flood: The Case of Houston and Hurricane Harvey

Abstract

The present study examines risk perceptions before and after a recent natural-technological event. The aim is to improve understanding of how long-time residents understand chronic and acute industrial risks, including hazardous industrial releases triggered by natural disasters. Thirty-two interviews were conducted in Channelview, Texas: 19 in February 2017, six months before Hurricane Harvey’s landfall, and 13 with those same residents in December 2017, four months after Harvey’s landfall. Results indicate that long-time residents normalized chronic risks of industrial pollution before the storm, but they were either unaware or incredulous that major industrial spills might result from a hurricane. After such an event, residents strengthened their normalization of industrial risks and became even more inclined to frame them as coming from external forces rather than from local facilities that continue to put their community at risk.     

Influence of Age on Transracial Foster Adoptions and Its Relation to Ethnic Identity Development

In the United States, ethnic minorities are disproportionately represented in the foster care system and underrepresented among potential adoptive parents. The need to find permanent homes for foster children has led to an increase in the controversial practice of transracial adoption (TRA), wherein ethnic minority children are placed in adoptive homes with Caucasian parents. While many child welfare scholars and dependency stakeholders support TRA as a positive alternative to foster care, others are concerned that such adoptions may inhibit the ethnic identity development of transracially adopted children. This article documents the large number of ethnic minority children who are adopted through TRA prior to the onset of ethnic identification and how age influences which children are adopted out of foster care. The findings indicate that young ethnic minorities are significantly more likely to be adopted through TRA compared to older children, an effect especially prominent among African Americans. Implications for the child welfare system are discussed.     

Undocumented Latina immigrants in Orange County,California: a comparative analysis

"This article examines a unique data set randomly collected from Latinas (including 160 undocumented immigrants) and non-Hispanic white women in Orange County, California, including undocumented and documented Latina immigrants, Latina citizens, and non-Hispanic white women. Our survey suggests that undocumented Latinas are younger than documented Latinas, and immigrant Latinas are generally younger than U.S.-citizen Latinas and Anglo women. Undocumented and documented Latinas work in menial service sector jobs, often in domestic services. Most do not have job-related benefits such as medical insurance.... Despite their immigration status, undocumented Latina immigrants often viewed themselves as part of a community in the United States, which significantly influenced their intentions to stay in the United States. Contrary to much of the recent public policy debate over immigration, we did not find that social services influenced Latina immigrants' intentions to stay in the United States."     

COMMON DUE-WINDOW SCHEDULING

In this paper, we solve common due-window scheduling problems within the just-in-time window concept, i.e., scheduling problems including both earliness and tardiness penalties. We assume that jobs share the same due window and incur no penalty as long as they are completed within the due window. We further assume that the earliness and tardiness penalty factors are constant and that the size of the window is a given parameter. For cases where the location of the due window is a decision variable, we provide a polynomial algorithm with complexity O(n * log (n)) to solve the problem. For cases where the location of the due window is a given parameter, we use dynamic programming with pseudopolynomial complexity to solve the problem.
