  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. Cumulative Effects of Bullying and Racial Discrimination on Adolescent Health in Australia

    This study examined how cumulative exposure to racial discrimination and bullying victimization influences the health of Australian adolescents (n = 2802) aged 10 to 11 years (19.3% visible ethnic minorities [nonwhite, non-Indigenous]; 2.6% Indigenous) using data from three waves (2010–2014) of the nationally representative Longitudinal Study of Australian Children (LSAC). Cumulative exposure to racial discrimination and bullying victimization had incremental negative effects on socioemotional difficulties.
  3. Adverse Childhood Experiences, Early and Nonmarital Fertility, and Women’s Health at Midlife

    Adverse childhood experiences (ACEs) have powerful consequences for health and well-being throughout the life course. We draw on evidence that exposure to ACEs shapes developmental processes central to emotional regulation, impulsivity, and the formation of secure intimate ties to posit that ACEs shape the timing and context of childbearing, which in turn partially mediate the well-established effect of ACEs on women’s later-life health.
  4. Preventing Violence: Insights from Micro-Sociology

    Micro-sociology of violence looks at what happens in situations where people directly threaten violence, but only sometimes carry it out. This process and its turning points have become easier to see in the current era of visual data: cell-phone videos, long-distance telephoto lenses, CCTV cameras. New cues and instruments are on the horizon as we look at emotional signals, body rhythms, and monitors for body signs such as heart rate (a proxy for adrenaline level).
  5. Imputing Data for the Fragile Families Challenge: Identifying Similar Survey Questions with Semiautomated Methods

    The Fragile Families Challenge charged participants to predict six outcomes for 4,242 children and their families interviewed in the Fragile Families and Child Wellbeing Study. These outcome variables are grade point average, grit, material hardship, eviction, layoff and job training. The data set provided contained longitudinal survey and observational data collected on families and their children from birth to age 9. The authors used these data to create models to make predictions at age 15.
  6. 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.
  7. CASM: A Deep-Learning Approach for Identifying Collective Action Events with Text and Image Data from Social Media

    Protest event analysis is an important method for the study of collective action and social movements and typically draws on traditional media reports as the data source. We introduce collective action from social media (CASM)—a system that uses convolutional neural networks on image data and recurrent neural networks with long short-term memory on text data in a two-stage classifier to identify social media posts about offline collective action. We implement CASM on Chinese social media data and identify more than 100,000 collective action events from 2010 to 2017 (CASM-China).
  8. Legally a Lady

    In a period of ambiguous legal culture between the U.S. Civil War and the legal imposition of Jim Crow, court cases reveal Black women navigating race, class, and gender as they sought a seat in the Ladies’ Car and claimed their right to dignity within American society.
  9. Collective Social Identity: Synthesizing Identity Theory and Social Identity Theory Using Digital Data

    Identity theory (IT) and social identity theory (SIT) are eminent research programs from sociology and psychology, respectively. We test collective identity as a point of convergence between the two programs. Collective identity is a subtheory of SIT that pertains to activist identification. Collective identity maps closely onto identity theory’s group/social identity, which refers to identification with socially situated identity categories. We propose conceptualizing collective identity as a type of group/social identity, integrating activist collectives into the identity theory model.
  10. Stealing a Bag of Potato Chips and Other Crimes of Resistance

    Sociologist Victor M. Rios shows in his study how some young men make trouble as means of gaining respect. This excerpt is an adaptation from his book Punished: Policing the Lives of Black and Latino Boys.
