Approaching Adoption and Foster Care in Brazil

Adoption and foster care have recently undergone various changes in Brazil. Nonetheless, there is a lack of official research data on children who have been adopted or have been living in foster families or institutions. In this paper, after a brief account of the historical aspects of adoption and foster care in Brazil, we focus our discussion on two major points: (1) the difficulties in promoting a “new culture of adoption,” which would develop in “the child's best interest,” and (2) the meanings and prejudices related to late adoption that increase the number of children who remain for many years in institutions.     

Seeking Social Security: An Alternative Motivation for Mexico-US Migration

In this analysis we investigate the degree to which the absence of effective pension systems may generate motivations for international migration as a means of self-financing retirement. Using ethnosurvey data gathered in selected Mexican communities and US destination areas, we estimate models to predict the odds of US migration from indicators of relative wages and whether or not jobs in Mexico were covered by that country's social security system. We find that by holding constant the binational differential in expected wages, the odds of out-migration were much higher for male household heads working in jobs that were not covered by social security compared with those working in jobs that enjoyed such coverage. Subsequent analyses showed that the odds of receiving a pension in old age were systematically higher for former US migrants, and that the likelihood of pension receipt rose steadily as the number of US trips and amount of US experience accumulated.     

Immigrants and natives in U.S. science and engineering occupations, 1994–2006

Between 1994 and 2006, the ratio of foreign-born scientists and engineers (FSE) to native scientists and engineers (NSE) doubled. I decompose this change into a migration effect (which accounts for migration in general), a proportional college effect (which accounts for the relative proportions of college graduates among migrant and native workers), and a proportional science and engineering (S&E) effect (which accounts for the relative proportions of S&Es among migrant and native college-educated workers). Results show that the migration effect explains about three-quarters of the increase in FSE/NSE during the entire period under study. The proportional S&E effect, which captures changes in the ratio as a result of immigration of S&Es in excess of what would be expected from general migration alone, was largest in 1995–1998, which were years of sustained economic growth. Conversely, a slower economy coincided with a declining proportional S&E effect after 2000. Increases in the annual cap on H-1B visas, an important avenue of entry for foreign-born S&Es, had little effect on the ratio. In short, during 1994–2006, the association between economic swings and the specific, more than proportional migration of S&Es was much stronger than the association between the latter and changes in the H-1B cap.     

A test of the stranger-interviewer norm in the Dominican Republic

We offer the first empirical test of the ‘stranger-interviewer norm’, according to which interviewers in social, demographic, and health surveys should be strangers—not personally familiar with respondents. We use data from an experimental survey in the Dominican Republic that featured three types of interviewer: from out of town (outsiders); local but unknown to the respondent (local-strangers); and local with a previous relationship to the respondent (insiders). We were able to validate answers to up to 18 questions per respondent, mainly by checking official documents in their possession. Contrary to expectations derived from the stranger-interviewer norm, respondents were more reluctant to show the documents needed for validation when the interviewer was an outsider. Furthermore, and again at odds with the stranger-interviewer norm, we found no difference in accuracy by type of interviewer. Our results have important implications for the selection of survey interviewers in less developed and non-Western settings.     

Experimental Analysis of the Game in Pathological Gamblers: Effect of the Immediacy of the Reward in Slot Machines

Slot machines are the most “addictive” games because (a) the disorder (pathological gambling) appears more rapidly in these games than with any other; (b) most patients who seek professional help are mainly addicted to electronic gambling, and (c) even though it is not the more frequent game, most of all the money spent on legal games of chance (at least in Spain) goes to slot machines. Structural characteristics of slot machines induce to gamble because electronic games show the main parameters of operant conditioning, mainly the immediacy of the reinforcement. Ten pathological gamblers played slot machine in two conditions: immediate and delayed reinforcement. The results corroborate the importance of the immediacy of the reinforcement in gambling, because when the result appears immediately (after 2 s), more games are played than when the result is delayed only 10 s. Critical issues in problem gambling prevention and public health are discussed.
