We exploit a policy designed to randomly allocate roommates in a large South African university to investigate whether interracial interaction affects stereotypes, attitudes and performance. Using implicit association tests, we find that living with a roommate of a different race reduces White students' negative stereotypes towards Black students and increases interracial friendships. Interaction also affects academic outcomes: Black students improve their GPA, pass more exams and have lower dropout rates. This effect is not driven by roommate's ability.

Concerned with poor service delivery, a large literature studies accountability of politicians to voters. This article instead considers accountability relationships within governments—the ability of politicians to implement policies by holding bureaucrats responsible for their actions. In collaboration with the Ugandan government, I conducted a field experiment across 260 local governments. The objective of the reform was to empower local politicians to exercise closer oversight over the bureaucracy through training and the dissemination of financial information. Lowered oversight costs increase politicians’ monitoring effort and the quality of services, but only in areas where the political leadership is not aligned with the dominant party. In areas under ruling-party control, politicians fear uncovering mismanagement of funds. In contrast to scholars arguing that insulating bureaucrats allows them to do their jobs more effectively, these findings imply that increased political oversight can improve government responsiveness in settings with a modicum of party competition.

Why do certain ideas catch on? What makes some ideas more powerful than others? Using a novel dataset that traces Chinese netizens’ discussion of U.S. politics on an online forum, this study examines key predictors of cultural power—novelty, emotion, status, and linguistic features—using an innovative diachronic word-embedding method. The study finds a curvilinear relationship between novelty and resonance, as well as a positive relationship between status and cultural power. Contrary to theoretical expectations, moderate emotions, whether positive or negative, are found to be more effective in evoking resonance than more intense emotions, possibly due to the mediating effect of the forum’s “group style.” Thus, it appears that although extreme sentiments toward the United States may exist, they are not likely to be resonant, at least among more educated Chinese netizens. The study also finds significant effects of linguistic features, such as lexical diversity and the use of English in Chinese discussions. This suggests a Bourdieusian “cultural capital signaling and selection” path to cultural power, which has not been considered in most studies of resonance.

Measuring timely high-resolution socioeconomic outcomes is critical for policymaking and evaluation, but hard to reliably obtain. With the help of machine learning and cheaply available data such as social media and nightlight, it is now possible to predict such indices in fine granularity. This article demonstrates an adaptive way to measure the time trend and spatial distribution of housing vitality (number of occupied houses) with the help of multiple easily accessible datasets: energy, nightlight, and land-use data. We first identified the high-frequency housing occupancy status from energy consumption data and then matched it with the monthly nightlight data. We then introduced the Factor-Augmented Regularized Model for prediction (FarmPredict) to deal with the dependence and collinearity issue among predictors by effectively lifting the prediction space, which is suitable to most machine learning algorithms. The heterogeneity issue in big data analysis is mitigated through the land-use data. FarmPredict allows us to extend the regional results to the city level, with a 76% out-of-sample explanation of the spatial and timeliness variation in the house usage. Since energy is indispensable for life, our method is highly transferable with the only requirement of publicly accessible data. Our article provides an alternative approach with statistical machine learning to predict socioeconomic outcomes without the reliance on existing census and survey data. Supplementary materials for this article are available online.

Biocultural approaches in anthropology originated from a desire to dissolve the nature/culture divide that is entrenched in the discipline. Whereas biocultural approaches were born under the umbrella of medical anthropology, by the late 1990s, biology-centered approaches to bioculturalism had been mostly taken up by human biologists in biological anthropology. It was at this point that biology-inclined approaches began to gel into an informal interdiscipline, biocultural anthropology. Much like any other discipline, biocultural anthropology developed research and professional norms with erected boundaries around acceptable work and workers. We draw from scholarly work in interdisciplinary studies to explore those norms and boundaries from the perspective of our collaborative, multimethod, and interdisciplinary project that combines “biology” and “culture” in unconventional ways. We provide examples of the obstacles, barriers, and risks we experienced and the costs exacted on the research project and the researchers due to the nature of our boundary crossings. By exploring biocultural anthropology from the edges of acceptability, we expose the unacknowledged boundary work in contemporary biocultural anthropology, and by extension, in its parent discipline, anthropology.

This article discusses how US military payment certificates (MPC) escaped from US military bases during the Korean War to become common currency in local economies. The MPC program was intended to control the mixing of US currency in local economies, yet the worldwide use of MPC on all overseas US bases between 1946 and 1973 facilitated black market circulation of military notes globally by allowing trading differentials among dollars, MPC, and local currencies. As soldiers, goods, and money moved through the US base network across Korea and Japan during the war, MPC were commonly used as a medium of exchange for sexual transactions between US soldiers and local women in both countries. The cross-border sexual markets were central to the everyday economies of Korea and Japan, of which black markets trading US Army supplies and currencies were major components. An analysis of this off-base monetization process of MPC offers a new perspective on the global history of war and occupation by highlighting how the sexual economy of illicit and informal transactions has been integral to US military expansion abroad since the end of World War II.

Youth from immigrant families often translate or interpret materials for their parents who lack proficiency in the dominant language of the mainstream society. However, evidence remains mixed regarding whether such a language brokering role is promotive or disruptive for youth’s well-being. This meta-analysis synthesized 65 studies (1,242 effect sizes, 17,791 individuals; grand Mage = 16.68, SDage = 4.78) to examine whether, how, and when brokering frequency and feelings were related to well-being. Language brokering frequency was inversely associated with youth’s positive family relationships (r = −.10) and socioemotional outcomes (r = −.10) and positively related to youth’s acculturation stress (r = .06). However, positive or negative language brokering feelings were stronger predictors of youth’ well-being or maladjustment (|r| = .10–.29). The associations between language brokering frequency and youth’s adjustment also varied across subgroups, with the effects of frequent language brokering being more detrimental for European immigrant-origin (vs. Latinx), female (vs. male), and foreign-born (vs. native-born) youth. These findings underscore the need for a nuanced understanding of the impacts of youth language brokering. Finally, practical and policy implications are discussed.
