Early abstract reasoning has typically been characterized by a “relational shift,” in which children initially focus on object features but increasingly come to interpret similarity in terms of structured relations. An alternative possibility is that this shift reflects a learned bias, rather than a typical waypoint along a universal developmental trajectory. If so, consistent differences in the focus on objects or relations in a child’s learning environment could create distinct patterns of relational reasoning, influencing the type of hypotheses that are privileged and applied. Specifically, children in the United States may be subject to culture-specific influences that bias their reasoning toward objects, to the detriment of relations. In experiment 1, we examine relational reasoning in a population with less object-centric experience—3-y-olds in China—and find no evidence of the failures observed in the United States at the same age. A second experiment with younger and older toddlers in China (18 to 30 mo and 30 to 36 mo) establishes distinct developmental trajectories of relational reasoning across the two cultures, showing a linear trajectory in China, in contrast to the U-shaped trajectory that has been previously reported in the United States. In a third experiment, Chinese 3-y-olds exhibit a bias toward relational solutions in an ambiguous context, while those in the United States prefer object-based solutions. Together, these findings establish population-level differences in relational bias that predict the developmental trajectory of relational reasoning, challenging the generality of an initial object focus and suggesting a critical role for experience.

Religion can have a favorable impact on individual-level health. The influence of religion on population health, however, remains less clear. This study investigated the association between religion and mortality at the population-level. Using county data, a meta-regression was performed to examine between-county mortality heterogeneity. The percent heterogeneity associated with religion variables were compared to demographics (i.e., place, race, language, age, and gender) and health factors (i.e., individual behaviors, clinical care, social and economic, and physical environment) as predictors of mortality. Religion was measured in terms of adherence (i.e., prevalence attending/belonging to a congregation), congregation density, and the diversity of adherents and congregation by denominations. Results showed counties with lower mortality were associated with higher proportions of religion adherents and a greater diversity of adherents and congregations. Counties with higher mortality were associated with higher religion congregation density. Religion, as a parsimonious multivariate model with all demographic and health factor predictors, had less added value when controlled for individual variables or constructs. The direction of association between religion and mortality was consistent, even when controlling for demographics and health factors, and thus merits further consideration as a population health determinant, as it may play a critical role in understanding other population health outcomes.

Building America: The Life of Benjamin Henry Latrobe is a biography of America’s first professionally trained architect and engineer. Born in 1764, Latrobe was raised in Moravian communities in England and Germany. His parents expected him to follow his father and brother into the ministry, but he rebelled against the church. Moved to London, he studied architecture and engineering. In 1795 he emigrated to the United States and became part of the period’s Transatlantic Exchange. Latrobe soon was famous for his neoclassical architecture, designing important buildings, including the US Capitol and Baltimore Basilica as well as private homes. Carpenters and millwrights who built structures more cheaply and less permanently than Latrobe challenged his efforts to establish architecture as a profession. Rarely during his twenty-five years in the United States was he financially secure, and when he was, he speculated on risky ventures that lost money. He declared bankruptcy in 1817 and moved to New Orleans, the sixth American city that he lived in, hoping to recoup his finances by installing a municipal water system. He died there of yellow fever in 1820. The themes that emerge in this biography are the critical role Latrobe played in the culture of the early republic through his buildings and his genius in neoclassical design. Like the nation’s political founders, Latrobe was committed to creating an exceptional nation, expressed in his case by buildings and internal improvements. Additionally, given the extensive primary sources available for this biography, an examination of his life reveals early American attitudes toward class, family, and religion.

Substance abuse is a major medical and social problem. Estimates suggest that each year some 15 percent of the 4 million babies born in the United States are exposed to drugs or alcohol. Research demonstrates that exposure to these substances is harmful to the children in both the short term and across their developmental trajectory. This chapter summarizes the harms that might result from such prenatal exposure and considers the ways that both federal and state law respond to this. The chapter argues for universal drug testing of newborns in an effort to ascertain whether they have been prenatally exposed to such substances so that treatment and other services can be provided.

Abstract Objective: Our objective was to compare patterns of dental antibiotic prescribing in Australia, England, and North America (United States and British Columbia, Canada). Design: Population-level analysis of antibiotic prescription. Setting: Outpatient prescribing by dentists in 2017. Participants: Patients receiving an antibiotic dispensed by an outpatient pharmacy. Methods: Prescription-based rates adjusted by population were compared overall and by antibiotic class. Contingency tables assessed differences in the proportion of antibiotic class by country. Results: In 2017, dentists in the United States had the highest antibiotic prescribing rate per 1,000 population and Australia had the lowest rate. The penicillin class, particularly amoxicillin, was the most frequently prescribed for all countries. The second most common agents prescribed were clindamycin in the United States and British Columbia (Canada) and metronidazole in Australia and England. Broad-spectrum agents, amoxicillin-clavulanic acid, and azithromycin were the highest in Australia and the United States, respectively. Conclusion: Extreme differences exist in antibiotics prescribed by dentists in Australia, England, the United States, and British Columbia. The United States had twice the antibiotic prescription rate of Australia and the most frequently prescribed antibiotic in the US was clindamycin. Significant opportunities exist for the global dental community to update their prescribing behavior relating to second-line agents for penicillin allergic patients and to contribute to international efforts addressing antibiotic resistance. Patient safety improvements will result from optimizing dental antibiotic prescribing, especially for antibiotics associated with resistance (broad-spectrum agents) or C. difficile (clindamycin). Dental antibiotic stewardship programs are urgently needed worldwide.

Many self-identified realist, liberal, and constructivist scholars contend that ideology played a critical role in generating and shaping the United States' decision to confront the Soviet Union in the early Cold War. A close look at the history reveals that these ideological arguments fail to explain key aspects of U.S. policy. Contrary to ideological explanations, the United States initially sought to cooperate with the Soviet Union, did not initially pressure communist groups outside the Soviet orbit, and later sought to engage communist groups that promised to undermine Soviet power. The U.S. decision to confront the Soviets stemmed instead from the distribution of power. U.S. policy shifted toward a confrontational approach as the balance of power in Eurasia tilted in favor of the Soviet Union. In addition, U.S. leaders tended to think and act in a manner consistent with balance of power logic. The primacy of power over ideology in U.S. policymaking—given the strong liberal tradition in the United States and the large differences between U.S. and Soviet ideology—suggests that relative power concerns are the most important factors in generating and shaping confrontational foreign policies.

Abstract Background Rapid entry programs (REPs) improve time to antiretroviral therapy (ART) initiation (TAI) and time to viral suppression (TVS). We assessed the feasibility and effectiveness of a REP in a large HIV clinic in Atlanta, Georgia, serving a predominately un- or underinsured population. Methods The Rapid Entry and ART in Clinic for HIV (REACH) program was implemented on May 16, 2016. We performed a retrospective cohort study with the main independent variable being period of enrollment: January 1, 2016, through May 15, 2016 (pre-REACH); May 16, 2016, through July 31, 2016 (post-REACH). Included individuals were HIV-infected and new to the clinic with detectable HIV-1 RNA. Six-month follow-up data were collected for each participant. Survival analyses were conducted for TVS. Logistic and linear regression analyses were used to evaluate secondary outcomes: attendance at first clinic visit, viral suppression, TAI, and time to first attended provider visit. Results There were 117 pre-REACH and 90 post-REACH individuals. Median age (interquartile range [IQR]) was 35 (25–45) years, 80% were male, 91% black, 60% men who have sex with men, 57% uninsured, and 44% active substance users. TVS decreased from 77 (62–96) to 57 (41–70) days (P < .0022). Time to first attended provider visit decreased from 17 to 5 days, and TAI from 21 to 7 days (P < .0001), each remaining significant in adjusted models. Conclusions This is the largest rapid entry cohort described in the United States and suggests that rapid entry is feasible and could have a positive impact on HIV transmission at the population level.

Abstract One of President Joseph Biden's foreign policy priorities is to ‘renew’ and ‘strengthen’ the United States' alliances, as they were perceived to have been ‘undermined’ during the Trump administration, which regularly expressed concern that allies were free-riding on the United States' military capability. Yet the broad range of threats states face in the contemporary context suggests that security assistance from allies no longer only—or even primarily—comes in the form of military capability. We consider whether there is a need to rethink understandings of how alliance relationships are managed, particularly how the goals—or strategic burdens—of alliances are understood, how allies contribute to those burdens, and how influence is exercised within alliances. We do this by analysing how the United States–Australia and Australia–New Zealand alliances operate in the Pacific islands. Our focus on the Pacific islands reflects the United States' perception that the region plays a ‘critical’ role in helping to ‘preserve a free and open Indo-Pacific region’. We conclude that these understandings need to be rethought, particularly in the Pacific islands, where meeting non-traditional security challenges such as economic, social and environmental issues, is important to advancing the United States, Australia and New Zealand's shared strategic goal of remaining the region's primary security partners and ensuring that no power hostile to their interests establishes a strategic foothold.
