Plumbing the brain drain.

Opportunity is the driving force of migration. Unsatisfied demands for higher education and skills, which have been created by the knowledge-based global economy, have generated unprecedented opportunities in knowledge-intensive service industries. These multi-trillion dollar industries include information, communication, finance, business, education and health. The leading industrialized nations are also the focal points of knowledge-intensive service industries and as such constitute centres of research and development activity that proactively draw in talented individuals worldwide through selective immigration policies, employment opportunities and targeted recruitment. Higher education is another major conduit of talent from less-developed countries to the centres of the knowledge-based global economy. Together career and educational opportunities drive "brain drain and recirculation". The departure of a large proportion of the most competent and innovative individuals from developing nations slows the achievement of the critical mass needed to generate the enabling context in which knowledge creation occurs. To favourably modify the asymmetric movement and distribution of global talent, developing countries must implement bold and creative strategies that are backed by national policies to: provide world-class educational opportunities, construct knowledge-based research and development industries, and sustainably finance the required investment for these strategies. Brazil, China and India have moved in this direction, offering world-class education in areas crucial to national development, such as biotechnology and information technology, paralleled by investments in research and development. As a result, only a small proportion of the most highly educated individuals migrate from these countries, and research and development opportunities employ national talent and even attract immigrants.

Race, region and the territorial politics of immigration in the US.

Zelinsky and Lee recently unveiled a model of the sociospatial process of immigrant settlement designed to augment and possibly supplant the well-known theories of assimilation and pluralism. Although in some ways new, their work continues a tradition in social science that treats the settlement geography of immigrants as a measure of their more general fit into American society. The authors question the prevailing assumption that immigrant settlement patterns represent a barometer of their adaptation, or lack thereof, to a host society. This critique of the concepts of assimilation, pluralism and Zelinsky and Lee's alternative "heterolocal" model of immigrant settlement pivots around the issues of spatial scale and race. The authors argue that the contestations over immigration and how well immigrants fit into society are increasingly constructed at the regional scale. The authors also assert that questions race infuse almost all aspects of these debates. The transformation of America's largest city-regions into places of non-White immigrants, and the shifting political balance of power to states like California through immigration-driven reapportionment, are touchstones for anti-immigration initiatives and associated local and national debate. Fear of racial regional changes underpins an increasingly powerful response to immigration. The reactions elicited by these settlement geographies fall under the heading the authors call the "territorial politics of immigration".

Inbreeding from isonymy and repeated pairs of surnames in the Ebro Delta region (Tarragona, Spain).

The aim of the study was to evaluate the levels of inbreeding calculated from isonymy with its random (Fr) and nonrandom (Fn) components, and repeated pairs of surnames (RP2) and their random component (RP2r) in the Ebro River Delta region (Tarragona, Spain). This region is made up of four parishes, and data correspond to the period 1939-1995. The global results are on the same levels as observed in other studies, but the values obtained in 3 of 4 parishes are relatively high. The Fn global value is higher than Fr, as opposed to what happens in each parish, so there is a clear Wahlund effect of subdivision of the region into parishes. Among the parishes there is a clear differentiation for Amposta, with values much lower than for the rest, due to the behavior of this population, i.e., a high immigration rate.

Friendship expectations among immigrant adolescents and their host peers.

This study investigated differences in friendship expectations between immigrants in early and middle adolescence and their Israeli-born peers. Israeli newcomers from the former Soviet Union and their non-immigrant classmates were asked to rate behavioural characteristics of peers according to the extent of their importance for friendship, and also to assess the importance of these characteristics as friendship expectations of members of the other group. Results indicate that immigrants assign greater importance than their host counterparts to all aspects of friendship expectations (help and assistance, status, similarity, and avoidance of harm). Immigrants also tend to view their host peers as expecting more of their friendship in terms of status and similarity, whereas host adolescents perceive the help and avoidance functions of friendship to be a strong factor in the friendship expectations of their immigrant counterparts. Immigrants' friendship expectations were found to be correlated with social distress, especially among early adolescent girls. The results are discussed in terms of the functions of friendships and friendship expectations in the immigrants' adaptation process, and of institutional differences in allocation of immigrants to integrated or segregated classrooms.

Effects of immigration on the dynamics of simple population models.

Many simple population models exhibit the period doubling route to chaos as a single parameter, commonly the growth rate, is increased. Here we examine the effect of an immigration process on such models and explain why in the case of one-dimensional ("single-humped") maps, immigration often tends to suppress chaos and stabilise equilibrium behaviour or cyclical oscillations of long period. The conditions for which an increase of immigration "simplifies" population dynamics are examined.

Psychosis in Asian immigrants from the Indian sub-continent: preliminary findings from a follow-up study including a survey of general practitioners.

The paper presents preliminary findings from a follow-up study of 86 first-generation immigrants to the United Kingdom from the Indian sub-continent, and a matched indigenous English-born control group. All subjects had originally been seen at the Bethlem Royal and Maudsley Hospitals and had been diagnosed as suffering from a functional psychosis. Attempts to locate the patients 5-20 years later revealed that a significantly higher proportion of the immigrant group could not be traced to a general practitioner within the United Kingdom, or otherwise accounted for. Possible explanations for this finding are advanced; the fact itself has important implications for those concerned with the provision of care and services for mentally ill immigrants in this country.

Vitamin D deficiency and susceptibility to tuberculosis.

Vitamin D, a modulator of macrophage function, can activate human anti-mycobacterial activity. Vitamin D deficiency is therefore associated with a higher risk of tuberculosis (TB) infection, as indicated by several observations. First, TB tends to occur during the colder seasons when cutaneous synthesis of vitamin D from sun exposure is reduced and serum vitamin D levels are lower. Second, patients with untreated TB, particularly those from a temperate climate, have lower serum vitamin D levels than healthy subjects. Third, the incidence of TB is higher among subjects with relatively low serum vitamin D levels, such as the elderly, uremic patients, and Asian immigrants in the U.K.

Optimal immigration, education and growth in the long run.

"The paper extends Manning's model on education and balanced growth to include labour immigration. Each immigration unit is assumed to consist of one skilled worker and some unskilled members. The optimal immigration policy which maximizes the per capita steady-state consumption of the host country is derived. We show that optimal immigration policy can reduce the steady-state skilled labour ratio. More interesting still, contrary to the widespread belief that immigration of skilled workers hurts local skilled workers, it is the unskilled local workers whose interests are threatened by optimal immigration policy."

International migration, economic policy and human capital accumulation: a simulation study.

"This paper examines the economic policy implications of international migration and human capital accumulation within a dynamic general equilibrium model. Each country produces by means of physical and human capital of two types (skilled and unskilled labour). Along optimal growth paths in a world of diverging population growth rates immigration can only be beneficial when the free rider effect (i.e., not paying for training costs) exceeds the capital dilution effect of an increase in population growth. Under quite general conditions the optimal immigration rate is zero."

Survey of tuberculous infection in schoolchildren in Bahrain.

A tuberculin survey was carried out on young schoolchildren in Bahrain and the results are compared with those of a previous survey. In 1969, with the co-operation of the World Health Organisation, a sample tuberculin survey was carried out on all age groups; it was found that 55 of the 897 children 6-7 years of age showed positive reactions (6.1%). In 1981, 12 years later, this same age group was surveyed again. A total of 6151 children was tested, of whom 86 were positive reactors (1.4%). This decline in the rate of tuberculous infection, by 12% a year, is highly significant (P much less than 0.001). The survey also shows a significantly higher rate of tuberculin positive reactors amongst immigrant children than amongst native Bahrainis.

The earnings of Mexican immigrants in the United States.

"This paper documents the trends in the earnings of Mexican immigrants during the 1970-1990 period. The empirical evidence indicates that there has been a decline in the relative wage of successive Mexican immigrant waves in the past three decades and that little wage convergence occurs between the typical Mexican immigrant and the typical native worker. The data also suggest that the increasing importance of Mexican immigration is partly responsible for the deterioration in relative skills observed in the aggregate immigrant population, but that there has also been a decline in relative skills even among non-Mexican immigrants."

The rise and fall of the medical gaze: the political economy of immigrant medical inspection in modern America.

In this paper I examine the mass medical inspections of immigrants to the United States from the 1890s through the 1920s. I show how, framed as it was not only by nativism and eugenics but also by national industrial imperatives and priorities, scientific medicine served dual purposes. On the one hand, the medical exam was a tool for managing cultural and biological threats to the nation. There were regional variations in medical inspections that reflected the politics of race. On the other hand, the medical exam played an important role in the process of building an unskilled, highly mobile labor force. The industrial demands of the nation provided a rationale for drawing and absorbing millions of European immigrants into the labor force. It was thus a distinct product of the political economy of immigration. It was this second function that characterized the exam for the majority of immigrants entering the nation.

The child immigrant.

This article uses a developmental perspective to look at the effects of immigration on the young child. Factors influencing the way in which the immigrant family negotiates the ongoing process of settling into the new country are considered. It is argued that the ability of parents to provide an adequate holding environment to protect the young child from too much loss or dislocation is probably the most critical factor in determining whether the child's internal world will be enriched or impoverished by the immigration experience. It is emphasized that immigration is an ongoing process for the entire family. Some clinical material is presented to illustrate how the child's engagement in the process of separation-individuation both shapes and is shaped by, the immigration experience.

Psychological distress among Mexican-American and Mexican women as related to status on the new immigration law.

Psychological distress in relation to the 1986 Immigration Reform and Control Act was examined among 90 Mexican-American and Mexican women divided into three groups (n = 30 each): undocumented immigrants who did not qualify for amnesty, undocumented immigrants who qualified for amnesty, and legal residents of the United States of Mexican descent. Results indicate that the undocumented immigrants who did not qualify for amnesty obtained significantly higher scores on hostility. Contrary to prediction, undocumented immigrants who qualified for amnesty obtained lower scores in anxiety (a statistical trend) than did the other two groups. No differences in global psychological distress were found between the undocumented immigrants and the legal residents.

Immigrants and equitable health-care delivery in rural areas.

In response to settlement patterns in Australia, most immigrant specialist services and programs have been developed in metropolitan locations and large provincial cities. However, immigrants have also settled in smaller numbers in country locations. It is of concern, therefore, to consider how responsive and equitable health-care services can be delivered in country regions when immigrants do not reach the critical mass that would warrant the development of specialist services. This paper draws on a consultation conducted in South Australia to propose a way forward in linking country health services with local immigrant communities and immigrant specialist services in cities.

Restructuring of the labour market and the role of third world migrations in Europe.

"This paper is an analysis of the way in which the changes in the labour market and in the occupational structure in Europe affect the situation and the role of Third World migrants." Changes in European labor migration patterns since the 1960s are first analyzed. The author notes that "intra-European migrations were industrial migrations because manufacturing and building industries were the most important and growing economic activities....Present-day migrations are postindustrial migrations. Immigrants work mostly in service activities and not infrequently in the informal economy. In any case migrant workers are located in the secondary labour market. The picture is made more complex by the fact than many immigrants are alegal or illegal because of the restrictive immigration policies in European countries."

Psychosocial predictors of acculturative stress in Mexican immigrants.

Psychosocial predictors of acculturative stress were examined in a sample of adult Mexican immigrants in Los Angeles. Bivariate and multivariate analyses revealed that family dysfunction, geographical separation from family, nonpositive expectations for the future, and low income levels were significantly related to elevated levels of acculturative stress. The findings suggest that family closeness, hopefulness for the future, and financial resources may provide a buffer against acculturative stressors experienced by migrating individuals. The findings highlight the importance of using culturally relevant clinical methods when assessing and treating immigrants and acculturating individuals.

Hospitalization due to alcohol and drug abuse in first- and second-generation immigrants: a follow-up study in Sweden.

The detrimental effects of substance abuse on the individual and on society are well known. Health care resources must target where they are most needed. This study investigated (1) whether the increased risk of being hospitalized for alcohol abuse and drug abuse among certain immigrant groups is present in the next generation and (2) whether having one parent born in the host country (i.e., Sweden) has a protective effect on the risk of being hospitalized for alcohol abuse and drug abuse among second-generation immigrants. In total, 2,243,546 persons aged 20-39 years were followed from 1 January 1992 until 31 December 1999 for first hospital admission due to alcohol abuse or drug abuse. A Cox regression model was used to estimate hazard ratios for each diagnosis group. When the Swedish majority population was used as reference, the highest risks of alcohol abuse and drug abuse were found among first- and second-generation Finns, after adjustment for income. Among second-generation Finns with one parent born in Sweden, the increased risk of being hospitalized for alcohol abuse and drug abuse was lower than among second-generation Finns with both parents born in Finland. Health care resources need to target certain groups of first- and second-generation immigrants.
