  1. Smoking Diffusion through Networks of Diverse, Urban American Adolescents over the High School Period

    This study uses recent data to investigate if smoking initiation diffuses through friendship networks over the high school period and explores if diffusion processes differ across schools. One thousand four hundred and twenty-five racially and ethnically diverse youth from four high schools in Los Angeles were surveyed four times over the high school period from 2010 to 2013. Probit regression models and stochastic actor-based models for network dynamics tested for peer effects on smoking initiation.
  2. Challenging Evolution in Public Schools: Race, Religion, and Attitudes toward Teaching Creationism

    Researchers argue that white evangelical Christians are likely to support teaching creationism in public schools. Yet, less is known about the role religion may play in shaping attitudes toward evolution and teaching creationism among blacks and Latinos, who are overrepresented in U.S. conservative Protestant traditions. This study fills a gap in the literature by examining whether religious factors (e.g., religious affiliation and Biblical literalism) relate to differences in support for teaching creationism between blacks and Latinos compared to whites and other racial groups.
  3. Predicting GPA at Age 15 in the Fragile Families and Child Wellbeing Study

    In this paper, we describe in detail the different approaches we used to predict the GPA of children at the age of 15 in the context of the Fragile Families Challenge. Our best prediction improved about 18 percent in terms of mean squared error over a naive baseline prediction and performed less than 5 percent worse than the best prediction in the Fragile Families Challenge. After discussing the different predictions we made, we also discuss the predictors that tend to be robustly associated with GPA. One remarkable predictor is related to teacher observations at the age of nine.
  4. Friend Request Pending: A Comparative Assessment of Engineering- and Social Science–Inspired Approaches to Analyzing Complex Birth Cohort Survey Data

    The Fragile Families Challenge is a mass collaboration social science data challenge whose aim is to learn how various early childhood variables predict the long-term outcomes of children. The author describes a two-step approach to the Fragile Families Challenge. In step 1, a variety of fully automated approaches are used to predict child academic achievement. In total 124 models are fit, which involve most possible combinations of eight model types, two imputation strategies, two standardization approaches, and two automatic variable selection techniques using two different thresholds.
  5. Winning Models for Grade Point Average, Grit, and Layoff in the Fragile Families Challenge

    In this article, the authors discuss and analyze their approach to the Fragile Families Challenge. The data consisted of more than 12,000 features (covariates) about the children and their parents, schools, and overall environments from birth to age 9.
  6. Sacred Alters: The Effects of Ego Network Structure on Religious and Political Beliefs

    Does who we know impact how strongly we believe? The claim seems reasonable, but research linking social network composition to political beliefs has produced conflicting results. We argue that methodological differences in measuring close ties can explain these inconsistencies and that work on the sacred umbrella provides a useful framework for moving forward. The sacred umbrella argues that when people close to you share your religious beliefs, you are shielded from doubt and uncertainty; perhaps the same mechanism also operates for political views.
  7. When Interest Doesn’t Turn into Action: Discrimination, Group Identification, and Muslim Political Engagement in the Post-9/11 Era

    This article examines the effect of exposure to post-9/11 stigmatization on various types of Muslim political engagement, using a mixed-methods approach that combines propensity score matching analysis of data from the Muslims in the American Public Square (MAPS) survey administered immediately after 9/11 with experimental data of the U.S. Muslim population. I find that increased discrimination results in increased political interest but has a neutral or dampening effect on political participation.
  8. Diverging Trajectories or Parallel Pathways? An Intersectional and Life Course Approach to the Gender Earnings Gap by Race and Education

    Integrating ideas about intersectionality with life course theories, we explore how trajectories of gender earnings inequality vary across race and education. Past research suggests that gender earnings gaps by race and education are narrower for more disadvantaged groups, yet it remains unknown whether these key differences amplify, decline, or remain constant over the life course.
  9. The Political-Military Foundations of China’s Global Ascendency

    In recent years China has positioned itself as a global economic leader, working through its “Belt and Road” initiative (BRI) and Asian Infrastructure Investment Bank (AIIB), to not only expand its global economic reach, but to organize and lead global economic relations. China’s rise is largely understood in economic terms, but the history of global power dynamics suggests that such leadership is built on both economic and political-military foundations.
  10. Equifinality and Pathways to Environmental Concern: A Fuzzy-Set Analysis

    Studying how people understand and develop concern for environmental problems is a key area of research within environmental sociology. Previous research shows that numerous social factors have measurable effects on environmental concern. However, results tend to be somewhat inconsistent across studies on this topic. One possible explanation for this is because these social factors are typically examined as independent from one another. However, these factors are interrelated in complex ways, as shown by research on the moderating effects of race and political ideology on education.
