Interactions, Actors, and Time: Dynamic Network Actor Models for Relational Events

Christoph Stadtfeld, Per Block

Sociological Science, May 15, 2017
DOI 10.15195/v4.a14

Ample theoretical work on social networks is explicitly or implicitly concerned with the role of interpersonal interaction. However, empirical studies to date mostly focus on the analysis of stable relations. This article introduces Dynamic Network Actor Models (DyNAMs) for the study of directed, interpersonal interaction through time. The presented model addresses three important aspects of interpersonal interaction. First, interactions unfold in a larger social context and depend on complex structures in social systems. Second, interactions emanate from individuals and are based on personal preferences, restricted by the available interaction opportunities. Third, sequences of interactions develop dynamically, and the timing of interactions relative to one another contains useful information. We refer to these aspects as the network nature, the actor-oriented nature, and the dynamic nature of social interaction. A case study compares the DyNAM framework to the relational event model, a widely used statistical method for the study of social interaction data.

Obesity Is in the Eye of the Beholder: BMI and Socioeconomic Outcomes across Cohorts

Vida Maralani, Douglas McKee

Sociological Science, April 19, 2017
DOI 10.15195/v4.a13

The biological and social costs of body mass cannot be conceptualized in the same way. Using semiparametric methods, we show that the association between body mass index (BMI) and socioeconomic outcomes such as wages, being married, and family income is distinctly shaped by gender, race, and cohort rather than being above a specific threshold of BMI. For white men, the correlation between BMI and outcomes is positive across the “normal” range of BMI and turns negative near the cusp of the overweight range, a pattern that persists across cohorts. For white women, thinner is nearly always better, a pattern that also persists across cohorts. For black men in the 1979 cohort, the association between BMI and wages is positive across the normal and overweight ranges for wages and family income and inverted U–shaped for marriage. For black women in the 1979 cohort, thinner is better for wages and marriage. By the 1997 cohort, however, the negative association between body mass and outcomes dissipates for black Americans but not for white Americans. In the social world, “too fat” is a subjective, contingent, and fluid judgment that differs depending on who is being judged, who does the judging, and the social domain.

More than Money: Social Class, Income, and the Intergenerational Persistence of Advantage

Carina Mood

Sociological Science, April 5, 2017
DOI 10.15195/v4.a12

I provide a uniquely comprehensive empirical integration of the sociological and economic approaches to the intergenerational transmission of advantage. I analyze the independent and interactive associations that parental income and social class share with children’s later earnings, using large-scale Swedish register data with matched parent–child records that allow exact and reliable measurement of occupations and incomes. I show that parental class matters at a given income and income matters within a given social class, and the net associations are substantial. Because measurement error is minimal, this result strongly suggests that income and class capture partly different underlying advantages and transmission mechanisms. If including only one of these measures, rather than both, we underestimate intergenerational persistence by around a quarter. The nonlinearity of the income–earnings association is found to be largely a compositional effect capturing the main effect of class.

Does Social Value Orientation Theory Apply to Social Relations?

Patricia Danielle Lewis, David Willer

Sociological Science, March 29, 2017
DOI 10.15195/v4.a11

This research asks whether Social Value Orientations (SVOs) apply to the social relations of exchange networks. SVO literature identifies three types of orientation to rational action, determined by how actors value outcomes to self and other. Only the individualist is the self-interested, rational actor previously seen in exchange networks. The prosocial actor seeks to maximize joint outcomes and equality whereas the competitor seeks to maximize differences between self and other. The competitor and individualist are frequently collapsed into a proself type. Whereas SVO research has focused on games and social dilemmas, this research places prosocials and proselfs in equal, weak, and strong power exchange structures. We show that, if SVO applies, the behaviors of proself and prosocial will be very different. Experimental results demonstrate, however, that prosocials’ actions in exchanges are indistinguishable from activities of proselfs.

Making Friends in Violent Neighborhoods: Strategies among Elementary School Children

Anjanette M. Chan Tack, Mario L. Small

Sociological Science, March 15, 2017
DOI 10.15195/v4.a10

While many studies have examined friendship formation among children in conventional contexts, comparatively fewer have examined how the process is shaped by neighborhood violence. The literature on violence and gangs has identified coping strategies that likely affect friendships, but most children in violent neighborhoods are not gang members, and not all friendship relations involve gangs. We examine the friendship-formation process based on in-depth interviews with 72 students, parents, and teachers in two elementary schools in violent Chicago neighborhoods. All students were African American boys and girls ages 11 to 15. We find that while conventional studies depict friendship formation among children as largely affective in nature, the process among the students we observed was, instead, primarily strategic. The children’s strategies were not singular but heterogeneous and malleable in nature. We identify and document five distinct strategies: protection seeking, avoidance, testing, cultivating questioners, and kin reliance. Girls were as affected as boys were, and they also reported additional preoccupations associated with sexual violence. We discuss implications for theories of friendship formation, violence, and neighborhood effects.

Fast or Slow: Sociological Implications of Measuring Dual-Process Cognition

Rick Moore

Sociological Science, February 27, 2017
DOI 10.15195/v4.a9

Dual-process theories of cognition within sociology have received increasing attention from both supporters and critics. One limitation in this debate, however, is the common absence of empirical evidence to back dual-process claims. Here, I provide such evidence for dual-process cognition using measures of response latency in formal data collected in conjunction with an ethnographic study of atheists and evangelicals. I use timed responses to help make sense of evangelicals’ language that frames “religion” as negative but “Christ-following” as positive. The data suggests that despite these Christians expressing a concept of the self that rejects “religion,” deep dispositions remain associating religion as a positive entity, not a negative one. I further argue that the significance of dual-process theories to sociology is in untangling such complex webs of identity discourse by distinguishing between immediate responses primarily due to fast cognition and those that are further mediated by slower, more deliberate cognition.

Deciding to Wait: Partnership Status, Economic Conditions, and Pregnancy during the Great Recession

Christine Percheski, Rachel Tolbert Kimbro

Sociological Science, February 20, 2017
DOI 10.15195/v4.a8

The Great Recession was associated with reduced fertility in the United States. Many questions about the dynamics underlying this reduction remain unanswered, however, including whether reduced fertility rates were driven by decreases in intended or unplanned pregnancies. Using restricted data from the 2006–2010 National Survey of Family Growth (N = 4,630), we exploit variation in state economic indicators to assess the impact of economic conditions on the likelihood of an intended pregnancy, an unplanned pregnancy, or no pregnancy for adult women without a college education. We focus on variations by partnership and marital status. Overall, we find that worse economic conditions were predictive of a lower risk of unplanned pregnancy. Women’s odds of intended pregnancy did not, however, respond uniformly to economic conditions but varied by marital status. When economic conditions were poor, married women had lower odds of intended pregnancy, whereas cohabiting women had greater odds of intended pregnancy.

The Decoupling of Sex and Marriage: Cohort Trends in Who Did and Did Not Delay Sex until Marriage for U.S. Women Born 1938–1985

Lawrence L. Wu, Steven P. Martin, Paula England

Sociological Science, February 13, 2017
DOI 10.15195/v4.a7

In this study, we examine cohort trends in who did and did not delay sex until marriage for U.S. women born between 1938 and 1985 using Cycles 3–7 of the National Survey of Family Growth. We find that roughly half of women born in the late 1930s and early 1940s were already sexually active prior to marriage. Especially rapid increases in not delaying sex until marriage occurred for women born between 1942–43 and 1954–55, with subsequent cohorts experiencing less rapid increases and with premarital sex reaching a plateau of roughly 85 to 90 percent for those born after 1962. Our continuous-time competing-risk models illustrate the methodological dangers of using single-decrement procedures for questions such as who did and did not delay sex until marriage. More generally, our findings suggest that the decoupling of sex and marriage was underway well before the so-called “sexual revolution” of the late 1960s and early 1970s.

Degrees of Difference: Gender Segregation of U.S. Doctorates by Field and Program Prestige

Kim A. Weeden, Sarah Thébaud, Dafna Gelbgiser

Sociological Science, February 6, 2017
DOI 10.15195/v4.a6

Women earn nearly half of doctoral degrees in research fields, yet doctoral education in the United States remains deeply segregated by gender. We argue that in addition to the oft-noted segregation of men and women by field of study, men and women may also be segregated across programs that differ in their prestige. Using data on all doctorates awarded in the United States from 2003 to 2014, field-specific program rankings, and field-level measures of math and verbal skills, we show that (1) “net” field segregation is very high and strongly associated with field-level math skills; (2) “net” prestige segregation is weaker than field segregation but still a nontrivial form of segregation in doctoral education; (3) women are underrepresented among graduates of the highest-and to a lesser extent, the lowest-prestige programs; and (4) the strength and pattern of prestige segregation varies substantially across fields, but little of this variation is associated with field skills.

Temporal Issues in Replication: The Stability of Centrality-Based Advantage

Yuan Shi, Olav Sorenson, David M. Waguespack

Sociological Science, January 30, 2017
DOI 10.15195/v4.a5

The results of archival studies may depend on when researchers analyze data for at least two reasons: (1) databases change over time and (2) the sampling frame, in terms of the period covered, may reflect different environmental conditions. We examined these issues through the replication of Hochberg, Ljungqvist, and Lu’s (2007) research on the centrality of venture capital firms and their performance. We demonstrate (1) that one can reproduce the results in the original article if one uses data downloaded at roughly the same time as the original researchers did, (2) that these results remain fairly robust to even a decade of database updating, but (3) that the results depend sensitively on the sampling frame. Centrality only has a positive relationship to fund performance during boom periods.
