Neural mechanisms lie behind the emergence of dyadic affective reciprocity and transitive closure in human groups
This talk considers a set of findings from socializing cognitive social neuroscience that captures neural and social network data at multiple time points for a group of students who volunteered to organize workers in very difficult social situations on the 50th anniversary of Freedom Summer, in the Summer of Respect project. We identify a neural mechanism for the emergence of affective reciprocity, the building block of social solidarity. We show that we can predict from neural signatures who group members will like five months in the future. We extend this work to a discussion of transitivity, or balance. Time permitting, we discuss how a neural signature of self-enhancement (narcissism) predicts becoming peripheral in small groups, supporting the idea that there is "no I in team".

The Reversal of the Gender Gap in Education and Family Dynamics in Europe
Although men tended to receive more education than women in the past, the gender gap in education has reversed in recent decades in most Western and many non-Western countries. In this talk, I will discuss the main results of a major research project that aimed to investigate the implications of the reversal of the gender gap in advanced education for family life across European countries. I highlight the results about union formation and assortative mating, discuss our findings about union stability as well as about husbands’ and wives’ relative earnings. Finally, I present some first results from research about implications for fertility behavior. To conclude, I will reflect on implications for conventional theories used in family sociology and demography.
Organizer: Ilan Meyer February 22, 2019 UCLA Faculty Center The target audience for the Workshop is students, post-docs, and early investigators. Participants will learn about the NIH structure and grant processes, meet NIH Program Officers and extramural researchers who have been successful at obtaining NIH funding, and network with others interested in SGM-related health research.
Covariate screening in high dimensional data: applications to forecasting and text data
High dimensional (HD) data, where the number of covariates and/or meaningful covariate interactions might exceed the number of observations, is increasing used in prediction in the social sciences. An important question for the researcher is how to select the most predictive covariates among all the available covariates. Common covariate selection approaches use ad hoc rules to remove noise covariates, or select covariates through the criterion of statistical significance or by using machine learning techniques. These can suffer from lack of objectivity, choosing some but not all predictive covariates, and failing reasonable standards of consistency that are expected to hold in most high-dimensional social science data. The literature is scarce in statistics that can be used to directly evaluate covariate predictivity. We address these issues by proposing a variable screening step prior to traditional statistical modeling, in which we screen covariates for their predictivity. We propose the influence (I) statistic to evaluate covariates in the screening stage, showing that the statistic is directly related to predictivity and can help screen out noisy covariates and discover meaningful covariate interactions. We illustrate how our screening approach can removing noisy phrases from U.S. Congressional speeches and rank important ones to measure partisanship. We also show improvements to out-of-sample forecasting in a state failure application. Our approach is applicable via an open-source software package.
Individual and Neighborhood Vulnerability over the Latin American Immigrant Health Experience
The state of Latino health seemingly defies the way in which the historical disadvantages faced by people of color in the United States get under the skin, and how place matters in reflecting or further reproducing these disparities. Hispanics –especially foreign-born individuals with lower socioeconomic statuses– have more favorable health than other race/ethnic groups –notably, U.S.-born non-Hispanic whites– in a limited but very important set of health outcomes such as cardiovascular function, some cancers and mortality across much of the life course.
In this talk, I discuss the mechanisms/phenomena driving the Hispanic immigrant health advantage, which is likely tied to processes of self-selection as well as to protection and resilience likely operating particularly well in heavily-concentrated Latino neighborhoods and enclaves. Throughout, I present my empirical research aimed at disentangling self-selection processes from the protection that immigrants might draw from fellow neighborhood and/or community members. I further discuss these findings in the context of how immigrants adapt in the longer term: these advantages and resilience eventually erode as immigrants spend more time in the United States –as well as across immigrant generations– through a series of processes by which immigrant and Latino vulnerability become somatized.
I conclude by speculating on the likely future of Latino and immigrant health, discussing how the resilience and vulnerability of Latino immigrants might evolve given recent major shifts U.S. immigration and social policies and practices, and due to important changes in the dynamics of migration between Mesoamerica and the United States.

The standard methods typically impose a mean outcome model as a function of individual features, time and their interactions. However, the validity of the estimators relies on the correct specifications […]
Immigrants’ Economic Assimilation: Evidence from Matched Administrative Records
Immigrants’ ability to succeed in the labor market and achieve economic parity with natives has significant long-term implications for their well-being and that of their children. In this talk I will present findings from two studies examining immigrants’ economic assimilation using a dataset that links respondents of the Survey of Income and Program Participation (SIPP) to their individual tax records. The first study examines the lifetime earnings trajectories of immigrants and measures the extent and speed with which they are able to reduce the earnings gap with natives. Findings from this study address key debates regarding ethnoracial and cohort differences in immigrants’ earnings trajectories. First, we find a racially differentiated pattern of earnings assimilation: black and Hispanic immigrants are less able to catch up with native whites’ earnings compared to white and Asian immigrants, but they are almost able to reach earnings parity with natives of their same race and ethnicity. Second, contrary to previous studies we find no evidence that recent immigrant cohorts are experiencing lower earnings growth. The second study examines immigrants’ job instability. We find that foreign-born men, particularly those who are undocumented, were at higher risk of losing their job and becoming involuntarily underemployed during the Great Recession even after controlling for demographic factors and job characteristics.

Small steps with Big Data: Using Machine Learning in Resource Economics
This talk looks at how recent developments in Big Data and Machine Learning are being used in conjunction with randomized controlled trials and large population level program evaluations to design, implement and measure efforts to change consumer behavior. We will explore the role played by very detailed consumption data (often at 15 minute intervals), as well as recent techniques such as deep learning to help us better understand individual and population behaviors, and which insights from behavioral sciences are effective at changing behaviors in areas such as energy conservation and efficiency.
Eloise Kaizar, Ohio State University Randomized controlled trials are often thought to provide definitive evidence on the magnitude of treatment effects. But because treatment modifiers may have a different distribution in a real world population than among trial participants, trial results may not directly reflect the average treatment effect that would follow real world adoption […]
Population Vulnerability and Spatial Analytics
There has been a transition from population studies that were relatively data poor to the present day where digital data is plentiful on many fronts. The “Smart City” is fed by sources of information coming from all directions, where sensors observe things about the movement of vehicles and people, infrastructure conditions, air quality, weather, etc. The challenge is to make use of this digital data, and this is precisely the value added offered by a range of big data spatial analytics. This paper examines aspects of population vulnerability, focusing on particular types of risks and hazards in urban areas.

Prep School for Poor Kids: The Long-Run Impacts of Head Start on Human Capital and Economic Self-Sufficiency
This paper evaluates the long-run effects of Head Start using large-scale, restricted 2000-2013 Census-ACS data linked to date and place of birth in the SSA’s Numident file. Using the county-level rollout of Head Start between 1965 and 1980 and state age-eligibility cutoffs for school entry, we find that participation in Head Start is associated with increases in adult human capital and economic self-sufficiency, including a 0.29-year increase in schooling, a 2.1-percent increase in high-school completion, an 8.7-percent increase in college enrollment, and a 19-percent increase in college completion. These estimates imply sizable, longterm returns to investing in large-scale preschool programs.
Live Births and Fertility amidst the Zika Virus Epidemic in Brazil
Abstract: In late 2015, the Brazilian Ministry of Health classified the increase in congenital malformations associated with the Zika Virus (ZIKV) a public health emergency. The risk of ZIKV-related congenital syndrome posed an exogenous threat to reproductive outcomes that could result in declining numbers of live births and potentially fertility. Using 2014-2016 monthly microdata on live births from the Brazilian Information System on Live Births, in this talk I examine live births and fertility trends amidst the ZIKV epidemic in Brazil. Findings suggest a decline in live births that is stratified across socioeconomic status and geographic lines, especially nine months after the call for pregnancy postponement. While declines in total fertility rates were small, fertility trends estimated by age and socioeconomic status suggest important differences in how Zika might have impacted Brazil’s fertility structure. Further findings using monthly data by municipality suggest that the epidemic resulted in a significant decline in fertility even when controlling for characteristics of the municipality. The findings highlight the importance of understanding how exposure to the risk of a health threat directed at fetuses has led to declines in fertility.
