Recent changes in migration patterns in the Mexico City metropolitan zone

"This study analyzes the magnitude, evolution over time, and place of origin of migrants to the ZMCM [Mexico City metropolitan zone] during the 1970s and 80s. More specifically, the study attempts to test the following hypothesis: attraction of migrants to the ZMCM has diminished over time;...thus the ZMCM is emerging as an important origin of migrants toward other cities. The article also provides an analysis of the changes in the characteristics of the migrants...." (SUMMARY IN ENG)

Y chromosome microsatellite genetic variation in two Native American populations from Argentina: Population stratification and mutation data

Two Native American populations from North and northwest regions of Argentina (Toba and Colla) were analyzed for 17 Y chromosome short tandem repeat loci (Y-STRs), namely, DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and GATA H4.1. Over 357 allele transfers, two one-step mutations could be detected at DYS456 and GATA H4.1 loci. A new 16.1 ‘micro-variant’ allele was observed for DYS385, characterized by an insertion at the fifth GAAA repeat. We also observed two alleles at the DYS448 locus in three samples (two from Toba and one from Colla). A total of 34 and 16 different haplotypes were detected for Toba and Colla, respectively, the former with a haplotype diversity value of 0.9769 ± 0.01, whereas 0.9497 ± 0.02 for the latter. Significant population differences were observed between Colla and Toba, at least in part, due to a more prevalent European input in the Colla. In agreement with this observation is the fact that the genetic distances between Colla and Iberian populations are lower than those observed between Iberian and any other Native American population. The results of multiscaling dimensional analysis and genetic distances (Rst) among Native American population samples also reflect this fact. The data show the existence of clear population stratification in the Argentina, a fact that should be taken into account in forensic casework.

Who Can Deviate from the Party Line? Political Ideology Moderates Evaluation of Incongruent Policy Positions in Insula and Anterior Cingulate Cortex

Political polarization at the elite level is a major concern in many contemporary democracies, which is argued to alienate large swaths of the electorate and prevent meaningful social change from occurring, yet little is known about how individuals respond to political candidates who deviate from the party line and express policy positions incongruent with their party affiliations. This experiment examines the neural underpinnings of such evaluations using functional MRI (fMRI). During fMRI, participants completed an experimental task where they evaluated policy positions attributed to hypothetical political candidates. Each block of trials focused on one candidate (Democrat or Republican), but all participants saw two candidates from each party in a randomized order. On each trial, participants received information about whether the candidate supported or opposed a specific policy issue. These issue positions varied in terms of congruence between issue position and candidate party affiliation. We modeled neural activity as a function of incongruence and whether participants were viewing ingroup or outgroup party candidates. Results suggest that neural activity in brain regions previously implicated in both evaluative processing and work on ideological differences (insula and anterior cingulate cortex) differed as a function of the interaction between incongruence, candidate type (ingroup versus outgroup), and political ideology. More liberal participants showed greater activation to incongruent versus congruent trials in insula and ACC, primarily when viewing ingroup candidates. Implications for the study of democratic representation and linkages between citizens’ calls for social change and policy implementation are discussed.

The Relationship between Homelessness and Behavior Problems among Youth in North Texas: a Brief Report

This study sought to examine the relationship between homelessness and behavior problems among a community-based sample of youth in North Texas. Data were obtained from a cross-sectional, probability sample of households and a targeted sample of homeless families in Dallas, Texas, with children older than 5 years old (N?=?5232). Parents were asked to report five behavior problems on behalf of their children including arrest or trouble with police, academic problems, behavior problems at school, suspension, and suicide attempts. Logistic and negative binomial regression procedures were used to examine the relationship between homelessness and behavior problems. Youth exposed to homelessness were 36% (OR?=?1.63; 95% CI 1.00–1.85) more likely to exhibit any kind of behavior problems than youth who had never experienced homelessness. Homeless youth had 5.51 times the odds of arrest (95% CI 2.60–11.68), 1.74 times the odds of academic problems (95% CI 1.24–2.43), and more than 3 times the odds of suicide attempts (95% CI 1.46, 7.61) than youth who had never been homeless. Homelessness was associated with higher rates of problem behavior, including arrests, academic problems, and suicide attempts. Because homeless youth are commonly enrolled in school and present at health care clinics and emergency departments, clinics and schools may aid in the identification of homeless youth, as well as referral to care. In this way, clinicians may help reduce the burden of behavioral problems that disproportionately affect homeless youth.
