Despite vast changes in women's status in society and in the home, we have little understanding of the changing role of mothers in shaping children's life chances. Mothers' contributions may have grown given their increased status-measured here as their education, occupational status, and earnings-and the rise of single-parent families. Using data from three large, nationally representative U.S. surveys, we find that the returns to mothers' status have remained relatively stable and similar to fathers' among children born from the 1930s to the 1980s and thus account for little of observed increases in children's college completion. But this does not mean nothing has changed. Our decomposition results show that the outsized role of recent increases in women's education, occupational status, and earnings for families' standard of living has meant that increased levels of mothers' status account for more of the increase in children's college completion than fathers' status among cohorts born since the 1960s. That continued increases in college completion have more to do with the rising status of mothers than fathers has been overlooked by previous research.

Childbearing norms and discourse influence social interactions and policy priorities, reflecting and reinforcing social stratification. We propose a theoretical framework that systematically explains stratification and discrimination in childbearing norms. The theory of socially sanctioned reproduction (TSSR) emphasizes how childbearing and reproductive norms are shaped by individual and intersectional attributes of both evaluators and those evaluated, underscoring multidimensionality and intersectionality in childbearing norms. We empirically examine this theory through paired conjoint survey experiments with a population-based sample of women ages 18 to 34 in Pernambuco, Brazil-a highly unequal, multiracial context. In our novel application, respondents assessed profiles of hypothetical married women with randomly varying attributes and reported whether they were well-suited for childbearing. Findings show how intersectional attributes and in-group/out-group dynamics, principally along race and SES lines, define childbearing norms. Black women receive less approval if in low- versus high-SES positions, whereas White women receive similar levels of approval regardless of SES. We find that these discriminatory patterns are shaped by the social attributes of evaluators themselves, suggesting othering and group attachment processes. Our theoretical and empirical frameworks can be extended to study norms in other highly contested areas of reproductive and family life.

Police culture creates an “us versus them” dynamic, which, at its worst, treats threats to the “thin blue line” as worthy of group response. Prior research documents such a group threat process as a possible mechanism for police misconduct, but few studies have analyzed the precise network relationships that serve as the conduit for a misconduct response. Using data on misconduct, officer injuries, and officer networks within the Chicago Police Department (CPD) between 2004 and 2015, this study examines the extent to which injuries officers receive from civilians might elicit a misconduct response from officers’ peers, and especially their direct network associates. Findings demonstrate that network ties to injured officers predict higher levels of subsequent misconduct, especially for officers with stronger ties to the injured officer. Furthermore, the effects of peer injury on subsequent misconduct are contingent on the race of the suspect involved: officers whose peers are injured are linked to more use of excessive force, as well as other types of misconduct, when the suspects involved are Black. These findings support our central hypothesis of a networked group threat response that links peer injuries to police misconduct.

This article analyzes academic freedom worldwide with newly available cross-national data. The literature principally addresses impingements on academic freedom arising from religion or repressive states. Academic freedom has broadly increased since 1945, but we see episodic reversals, including in recent years. Conventional work emphasizes the uniformity of international institutional structures and their influence on countries. We attend to the heterogeneity of international structures in world society and theorize how they contribute to ebbs and flows of academic freedom. Post-1945 liberal international institutions enshrined key rights and norms that bolstered academic freedom worldwide. Alongside them, however, illiberal alternatives coexisted. Cold War communism, for instance, anchored cultural frames that justified greater constraints on academia. We evaluate domestic and global arguments using regression models with country fixed effects for 155 countries from 1960 to 2022. Findings support conventional views: academic freedom is associated positively with democracy and negatively with state religiosity and militarism. We also find support for our argument regarding heterogeneous institutional structures in world society. Country linkages to liberal international institutions are positively associated with academic freedom. Illiberal international structures and organizations have the opposite effect. Heterogeneous institutions in world society, we contend, shape large-scale trajectories of academic freedom.

Prudence L. Carter
In the 2023 ASA presidential address, Prudence Carter delves into the landscape of U.S. society, tracing some of its historical progress and confronting contemporary social, economic, educational, and political challenges. Central to her argument is an exploration of the concept of “unrealized integration” and how it has hindered the nation’s march toward an inclusive, multiracial democracy. Carter describes and characterizes the current state of integration within education and society. Despite the widespread rhetoric of diversity in our organizations and institutions, she critiques its shallow application, exposing diversity’s inability to rectify imbalances of power- and resource-sharing. Incorporating the idea of “tipping points,” she discusses how civil rights movements, despite expanding representation and opportunity, have faced recurrent waves of political backlash and reversals. She contends that an erosion of social progress occurs when there is an imbalance in the pursuit of distributional equality (concerning material resources) and relational equality (involving social and cultural dynamics and processes that shape well-being). Additionally, she identifies three other crucial areas that warrant focus to pave the path toward realized integration within education and society. In a forward-looking call to arms, Carter underscores the imperative for sociologists to transcend epistemological and methodological boundaries; and she advocates for robust collaborations across the social sciences and humanities to harness the collective power of knowledge-generation and solution-building for pressing societal issues.

Research on tokenism has mostly focused on negative experiences and career outcomes for individuals who are tokenized. Yet tokenism as a structural system that excludes larger populations, and the meso-level cultural foundations under which tokenism occurs, are comparatively understudied. We focus on these additional dimensions of tokenism using original data on the creation and long-term retention of postcolonial literature. In an institutional environment in which the British publishing industry was consolidating the production of non-U.S. global literatures written in English, and readers were beginning to convey status through openness in cultural tastes, the conditions for tokenism emerged. Using data on the emergence of postcolonial literature as a category organized through the Booker Prize for Fiction, we test and find for non-white authors (1) evidence of tokenism, (2) unequal treatment of those under consideration for tokenization, and (3) long-term retention consequences for those who were not chosen. We close with a call for more holistic work across multiple dimensions of tokenism, analyses that address inequality across and within groups, and a reconsideration of tokenism within a broader suite of practices that have grown ascendent across arenas of social life.

Despite social scientists’ long-standing interest in the influences of siblings, previous research has not settled the debates on how relevant sibship size is to child development and whether growing up with more siblings could be beneficial. Using 30 years of longitudinal data and fixed-effects models, this study offers the most comprehensive evidence on how sibship size is tied to cognitive and sociobehavioral development. We also advance the literature by systematically comparing the consequences of gaining a sibling for children with varying ordinal positions. Contrary to prior studies using selective data from limited observation spans, we find that children experience net decreases in cognitive test scores as their family size grows. At the same time, our analysis shows that sibling additions are only important to first- and second-born children’s—not later-born children’s—cognitive development. Even for the first- and second-born, the marginal effect of adding a sibling lessens with each addition. Our results thus demonstrate the time-dependent nature of family resource-dilution processes. For sociobehavioral development, the evidence indicates that having an older sibling is beneficial, but gaining a younger sibling increases behavioral problems for some (e.g., first-born children). Because more children from large families have older siblings, children from larger families exhibit less problematic behavior, on average. By uncovering the complex relationship between siblings and noncognitive development, this study also generally contributes to the sociology of family and inequality.

In the throes of an intractable overdose crisis, U.S. pharmacists have begun to engage in an unexpected practice—policing patients. Contemporary sociological theory does not explain why. Theories of professions and frontline work suggest professions closely guard jurisdictions and make decisions based on the logics of their own fields. Theories of criminal-legal expansion show that non-enforcement fields have become reoriented around crime over the past several decades, but past work largely focuses on macro-level consequences. This article uses the case of pharmacists and opioids to develop a micro-level theory of professional field reorientation around crime, the Trojan Horse Framework. Drawing on 118 longitudinal and cross-sectional interviews with pharmacists in six states, I reveal how the use of prescription drug monitoring programs (PDMPs)—surveillance technology designed for law enforcement but implemented in healthcare—in conjunction with a set of field conditions motivates pharmacists to police patients. PDMPs serve as Trojan horse technologies as their use shifts pharmacists’ routines, relationships with other professionals, and constructions of their professional roles. As a result, pharmacists route patients out of the healthcare system and leave them vulnerable to the criminal-legal system. The article concludes with policy recommendations and a discussion of future applications of the Trojan Horse Framework.
