Reliability of the preliminary results of the Eleventh Census of Population and Housing of 1990

The author assesses the reliability of the eleventh general population and housing census conducted in Mexico in March 1990. An undercount of as many as two million persons is estimated. (SUMMARY IN ENG)     

Screening practices for adolescent dating violence

This study sought to determine the screening practices of child and adolescent psychiatrists regarding adolescent dating violence (DV). A questionnaire regarding screening practices for DV and other risk behaviors was administered to 817 child and adolescent psychiatrists via the Internet and mail. Twenty-one percent of clinicians screened for DV "more than 90% of the time," and 65% had identified it in the past year. Multiple logistic regression analyses found that screening for DV was associated with consistent screening for either substance use or interparental violence (OR=3.0 and 6.3, respectively). Despite the prevalence of DV, only a minority of psychiatrists screen their adolescent patients for this type of risk. These data suggest that screening for DV is associated with consistent screening practices for other risk behaviors. Screening rates may be improved with training and adherence to specific protocols.

Shaping of the migratory process in northern Mexico, 1930-1990

"During the third decade of this century Mexican geographical structure began to change notoriously. Due to the strong influence of [the] North American economy, the north of Mexico became progressively one of the most important regions in the country, with the emergence of favorable perspectives of economic growth. Soon it became attractive to migration from the demographically pressed regions of Central Mexico. Thus, the north of Mexico was favored by the presence of qualified workers and a growing population. However, the region was not evenly populated, due to geographic, historic, and socio-economic factors that...[affect] the processes of migration and settlement. Some regions present important changes in their migratory flow, evidenced by the presence of new entities of origin and the disappearance of others." (SUMMARY IN ENG)     

Assessing the instrumental and symbolic elements in attitudes toward the death penalty using a sample of Puerto Rican students

Theoretical explanations for the support or opposition to the death penalty have often been dichotomized into the instrumental and the symbolic perspectives. The instrumental perspective sees support for the death penalty as utilitarian, that it is a means to a desired end, which is often to lower crime rates. The symbolic perspective sees support for the death penalty as emanating from individuals’ political and social ideologies, no matter its utilitarian value. Both perspectives have often been examined individually, and seldom juxtaposed as competing explanations in a singular model. This paper examines both perspectives in a singular model, using a sample of Puerto Rican students.     

INITIAL DEVELOPMENT OF A PSYCHOLOGICAL MODEL FOR JUDICIAL DECISION MAKING IN CONTINUING RESTRAINING ORDERS

Probate and family court judges are increasingly called upon to make rapid decisions regarding the continuance of restraining orders. These decisions are often made without the benefit of adequate background information or an awareness of which psychological and behavioral factors are most relevant. This action‐oriented research project develops a model that brings psychosocial factors to consideration for judges making decisions regarding the continuance of restraining orders. While further evaluation of the model is needed, the project's unique methodology highlights the value of interdisciplinary collaboration, multiple methods of inquiry, and the consideration of real‐world needs and constraints in developing decision‐making tools.     

The rise of biofuels in IR: the case of Brazilian foreign policy towards the EU

Biofuels are a growing alternative energy source. In a context of their growing global consumption, Brazil has shown particular interest in the European market. This paper analyses Brazilian foreign policy on biofuels towards the EU during Lula da Silva’s administration (2003–10). It examines the emergence of biofuels at a global level, the main guidelines of Brazilian foreign policy, Brazilian environmental foreign policy and, finally, the Brazilian political response to changes in European law.     

Comparing Inference Approaches for RD Designs: A Reexamination of the Effect of Head Start on Child Mortality

The regression discontinuity (RD) design is a popular quasi‐experimental design for causal inference and policy evaluation. The most common inference approaches in RD designs employ “flexible” parametric and nonparametric local polynomial methods, which rely on extrapolation and large‐sample approximations of conditional expectations using observations somewhat near the cutoff that determines treatment assignment. An alternative inference approach employs the idea of local randomization, where the very few units closest to the cutoff are regarded as randomly assigned to treatment and finite‐sample exact inference methods are used. In this paper, we contrast these approaches empirically by re‐analyzing the influential findings of Ludwig and Miller ( 2007 ), who studied the effect of Head Start assistance on child mortality employing parametric RD methods. We first review methods based on approximations of conditional expectations, which are relatively well developed in the literature, and then present new methods based on randomization inference. In particular, we extend the local randomization framework to allow for parametric adjustments of the potential outcomes; our extended framework substantially relaxes strong assumptions in prior literature and better resembles other RD inference methods. We compare all these methods formally, focusing on both estimands and inference properties. In addition, we develop new approaches for randomization‐based sensitivity analysis specifically tailored to RD designs. Applying all these methods to the Head Start data, we find that the original RD treatment effect reported in the literature is quite stable and robust, an empirical finding that enhances the credibility of the original result. All the empirical methods we discuss are readily available in general purpose software in R and Stata; we also provide the dataset and software code needed to replicate all our results.
