  1. Frame-Induced Group Polarization in Small Discussion Networks

    We present a novel explanation for the group polarization effect whereby discussion among like-minded individuals induces shifts toward the extreme. Our theory distinguishes between a quantitative policy under debate and the discussion’s rhetorical frame, such as the likelihood of an outcome. If policy and frame position are mathematically related so that frame position increases more slowly as the policy becomes more extreme, majority formation at the extreme is favored, thereby shifting consensus formation toward the extreme.
  2. Causal Inference with Networked Treatment Diffusion

    Treatment interference (i.e., one unit’s potential outcomes depend on other units’ treatment) is prevalent in social settings. Ignoring treatment interference can lead to biased estimates of treatment effects and incorrect statistical inferences. Some recent studies have started to incorporate treatment interference into causal inference. But treatment interference is often assumed to follow a simple structure (e.g., treatment interference exists only within groups) or measured in a simplistic way (e.g., only based on the number of treated friends).
  3. Limitations of Design-based Causal Inference and A/B Testing under Arbitrary and Network Interference

    Randomized experiments on a network often involve interference between connected units, namely, a situation in which an individual’s treatment can affect the response of another individual. Current approaches to deal with interference, in theory and in practice, often make restrictive assumptions on its structure—for instance, assuming that interference is local—even when using otherwise nonparametric inference strategies.
  4. Social Networks and Educational Attainment among Adolescents Experiencing Pregnancy

    Pregnant adolescents are a population at risk for dropout and have been found to complete fewer years of education than peers. Pregnant girls’ social experience in school may be a factor in their likelihood to persist, as social integration is thought to buffer dropout risk. Pregnant teens have been found to have fewer friends than their peers, but the academic ramifications of these social differences have yet to be studied. In this study the author examines whether friendship networks are associated with the relationship between adolescent pregnancy and educational attainment.

  5. Higher Education, Bigger Networks? Differences by Family Socioeconomic Background and Network Measures

    Income or health returns linked to obtaining a college degree often are greatest for individuals who come from socioeconomically disadvantaged families. Although this importantly suggests that college lessens many forms of inequality linked to parental socioeconomic status, empirical knowledge about adult network inequality remains limited. Drawing on the 1972–2014 General Social Survey, the author finds that higher education associates on average with a greater number of nonkin and community ties.
  6. Visualizing Stochastic Actor-based Model Microsteps

    This visualization provides a dynamic representation of the microsteps involved in modeling network and behavior change with a stochastic actor-based model. This video illustrates how (1) observed time is broken up into a series of simulated microsteps and (2) these microsteps serve as the opportunity for actors to change their network ties or behavior. The example model comes from a widely used tutorial, and we provide code to allow for adapting the visualization to one’s own model.

  7. A Novel Measure of Moral Boundaries: Testing Perceived In-group/Out-group Value Differences in a Midwestern Sample

    The literature on group differences and social identities has long assumed that value judgments about groups constitute a basic form of social categorization. However, little research has empirically investigated how values unite or divide social groups. The authors seek to address this gap by developing a novel measure of group values: third-order beliefs about in- and out-group members, building on Schwartz value theory. The authors demonstrate that their new measure is a promising empirical tool for quantifying previously abstract social boundaries.
  8. Discipline and Punish: The Birth of the Prison

    Stanley Cohen revisits Foucault's _Discipline and Punish: The Birth of the Prison_.
  9. Urban Hospitals as Anchor Institutions: Frameworks for Medical Sociology

    Recent policy developments are forcing many hospitals to supplement their traditional focus on the provision of direct patient care by using mechanisms to address the social determinants of health in local communities. Sociologists have studied hospital organizations for decades, to great effect, highlighting key processes of professional socialization and external influences that shape hospital-based care. New methods are needed, however, to capture more recent changes in hospital population health initiatives in their surrounding neighborhoods.
  10. Invited Feature Review: The Enslaved, the Worker, and Du Bois’s Black Reconstruction: Toward an Underdiscipline of Antisociology

    At the heart of sociology lies a paradox. Sociology recognizes itself as a preeminently modern discipline yet remains virtually silent on what W.E.B. Du Bois identifies as modernity’s “most magnificent drama”: the transoceanic enslavement of Africans. Through a reconsideration of his classic text Black Reconstruction in America, this article offers an answer to the paradox: a profoundly antisocial condition, racial slavery lies beyond the bounds of the social, beyond sociology’s self-defined limits.
