Migration Policy and Development in Chile

Current and prospective migration law and policy in Chile does not adequately incorporate the causes, content, and consequences of international migration to and from Chile. We describe and examine migration in‐flows, out‐flows, migration‐related policies, and how those policies drive, and are driven by, notions of development in Chile. We explore contradictions in Chilean nascent migration policy currently under legislative review. We argue that it is imperative that migration, migration policy, and their relationship to development be discussed inclusively and transparently and be explicitly incorporated into the Chilean government's nascent migration and development legal policies and frameworks.     

The Development of Referential Communication and Autism Symptomatology in High‐Risk Infants

Non‐verbal referential communication is impaired in children with autism spectrum disorders (ASD). However, the development of difficulties with referential communication in the younger siblings of children with ASD (High‐Risk Siblings)—and the degree to which early referential communication predicts later autism symptomatology—is not clear. We modeled the early developmental trajectories of three types of referential communication: responding to joint attention (RJA), initiating joint attention (IJA), and initiating behavioral requests (IBR) across 8, 10, 12, 15, and 18 months of age in High‐Risk Siblings (n = 40) and the infant siblings of children without ASD (Low‐Risk Siblings; n = 21). Hierarchical linear modeling indicated that High‐Risk Siblings exhibited lower levels of baseline RJA and IJA and a lower rate of linear change in IBR than Low‐Risk Siblings. When the 10 High‐Risk Siblings who received an ASD diagnosis were excluded from analyses, group differences in the development of referential communication remained significant only for RJA. Baseline levels of IJA were associated with later ASD symptomatology among High‐Risk Siblings, suggesting that individual differences in referential communication development at 8 months may index early manifestations of ASD.     

“Police,Public Safety,and Race‐Neutral Discourse”

In the final decades of the 20th century policing in America was refashioned in the public image of community policing. Race‐neutral discourses dominate public and professional support for community‐oriented policing philosophies. In the contemporary era of hyper‐incarceration a focus on ethnoracial divisions grounded in the sociology of peculiar institutions is essential for documenting transformations in how the municipal police services are legitimized. Here I analyze how the public discourses of law‐and‐order center on distortions of social fact and public safety. Today the criminalization of immigrants is the latest turn in public discourses shaping patterns of ethnoracial visions and divisions. The carceral breadth of the neoliberal penal state extends beyond social structure, repackaged as race‐neutral ideology across the public sphere.     

Towards a Socio‐Economics of the Brain Drain and Distributed Human Capital

This paper derives from our joint interest in understanding how scientific mobility affects developing countries. Many authors have addressed the topic previously, both from an economic and from a sociological perspective. However, recent literature evinces dissatisfaction with both analytical frameworks and the framing of public policies addressing the brain drain problematic. This paper is a contribution to understanding the historical and theoretical foundations of the “brain drain” debate. We aim to improve conceptual clarity regarding the itinerancy of human beings and the mobilization of human capital. We develop a critical review of the economics of the brain drain, highlighting the work of some key early thinkers and pointing out the way in which subsequent work has taken up selected aspects of their approaches leaving other challenges aside. We then consider the diaspora networks literature, which is characterized as taking a “connectionist” approach to the brain drain. We identify two fundamental problems: the sidelining of complementarity and context dependency as basic properties of human capital; and a failure to adequately disentangle the concepts of human resources for science and technology (HRST) and human capital in academic and policy discourse about the brain drain.     

Inequality in the “Cradle of Liberty”: Race/Ethnicity and Wealth in Greater Boston

New data collected for the Boston Metropolitan Statistical Area provide detailed information on financial assets that allow analysis to extend beyond the traditional black–white divide. Targeting US-born blacks, Caribbean blacks, Puerto Ricans, Dominicans, and other Hispanics, findings from the National Asset Scorecard for Communities of Color survey underscore the large racial and ethnic disparities in financial wealth, even after controlling for demographic and socioeconomic status. Further, some notable differences between Boston’s communities of color highlight the importance of detailed analyses for research on the racial wealth gap. In particular, among non-white communities Dominicans report comparatively low asset and high debt amounts, while Caribbean blacks report relatively higher levels of wealth. Altogether, these findings point to the need for wealth building opportunities in communities of color and further investigation of the causes and consequences of financial disparities between groups of color disaggregated by specific ancestral origin.     

Frequentist and Bayesian approaches for a joint model for prostate cancer risk and longitudinal prostate-specific antigen data

The paper describes the use of frequentist and Bayesian shared-parameter joint models of longitudinal measurements of prostate-specific antigen (PSA) and the risk of prostate cancer (PCa). The motivating dataset corresponds to the screening arm of the Spanish branch of the European Randomized Screening for Prostate Cancer study. The results show that PSA is highly associated with the risk of being diagnosed with PCa and that there is an age-varying effect of PSA on PCa risk. Both the frequentist and Bayesian paradigms produced very close parameter estimates and subsequent 95% confidence and credibility intervals. Dynamic estimations of disease-free probabilities obtained using Bayesian inference highlight the potential of joint models to guide personalized risk-based screening strategies.     

A Correlation Test for Normality Based on the Lévy Characterization

A powerful test of fit for normal distributions is proposed. Based on the Lévy characterization, the test statistic is the sample correlation coefficient of normal quantiles and sums of pairs of observations from a random sample. Since the test statistic is location-scale invariant, critical values can be obtained by simulation without estimating any parameters. It is proved that this test is consistent. A power comparison study including some directed tests shows that the proposed test is competitive, it is more powerful than the well-known Jarque–Bera test, and it is comparable to Shapiro–Wilk test against a number of alternatives.
