Seasonal patterns and protection status of stopover hotspots for migratory landbirds in the eastern United States.

Migratory landbirds in North America are experiencing dramatic population declines. Although considerable research and conservation attention have been directed toward these birds' breeding and wintering grounds, far less is known about the areas used as stopover sites during migration. To address this knowledge gap, we used 5 years of weather surveillance radar data to map seasonal stopover densities of landbirds across the eastern United States during spring and autumn migration.

Introduction of Medicare coverage in opioid treatment programs: Findings from the first three years.

Background: Prior to January of 2020, there was no Medicare reimbursement for services delivered in opioid treatment programs (OTPs). OTPs are the only authorized providers of opioid use disorder (OUD) treatment with methadone, a critical tool to address the opioid overdose crisis. While prior research has examined the availability of MOUD other than methadone for Medicare beneficiaries, research has not identified organizational and local Medicare beneficiary characteristics associated with Medicare insurance acceptance among OTPs.

Conducting Ethical Field Research on Rape in West African Settings: Case Study of 2018 Liberian Field Survey.

Background: Rape scholarship in West Africa is growing, but studies often utilize Westernized approaches. A 2018 study using a randomized survey design assessing rape among Liberian girls incorporated modified survey design methods to improve ethical data collection relevant to the cultural and contextual contexts. This article presents the findings of a thorough review of rape scholarship and design methods.

Deploying green hydrogen to decarbonize China's coal chemical sector.

China's coal chemical sector uses coal as both a fuel and feedstock and its increasing greenhouse gas (GHG) emissions are hard to abate by electrification alone. Here we explore the GHG mitigation potential and costs for onsite deployment of green H and O in China's coal chemical sector, using a life-cycle assessment and techno-economic analyses. We estimate that China's coal chemical production resulted in GHG emissions of 1.

The Systems Measurement of Mammalian Biotas, Part Two.

For a recent publication, the authors identified a seven-region model of mammal family distribution patterns, in which each unit contributes equally to the system's overall statistical characteristics of diversity, despite its individual units having measurably different levels of diversity and endemism. This systemization presents a highly efficient descriptive model that can possibly be interpreted as a form of natural classification. An additional analysis of the same mode is described here, in which the seven-region model of the distribution of mammal families' spatial affinities is shown to closely approach a most-probable-state arrangement, as assessed through combinatorics, raising some important questions about how macroevolutionary patterns might self-organize spatially.

Association of Dietary Changes with Risk Factors of Type 2 Diabetes among Older Adults in Sharpeville, South Africa, from 2004 to 2014.

This study aimed to evaluate the associations of dietary changes with risk factors of type 2 diabetes among older populations in Sharpeville, South Africa. A 24 h recall assessment, dietary diversity, and anthropometrics were measured. Blood samples were collected to assess fasting glucose and insulin.

A framework for coastal flood hazard assessment under sea level rise: Application to the Persian Gulf.

Coastal areas are of paramount importance due to their pivotal role in facilitating a wide range of socio-economic activities and providing vital environmental services. These areas, as the meeting points of land and sea, face significant risks of flooding due to the ongoing rise in sea levels caused by climate change. Additionally, they are susceptible to extreme events like king tides and large waves in the future.

Estimating the value of democracy relative to other institutional and economic outcomes among citizens in Brazil, France, and the United States.

How much do citizens value democracy? How willing are they to sacrifice their liberties and voting rights for growth, equality, or other social outcomes? We design a conjoint experiment in nationally representative surveys in Brazil, France, and the United States in which respondents choose between different societies that randomly vary in their economic outcomes (country income, income inequality, social mobility), political outcomes (democracy, public health insurance), and the level of personal income for each respondent. Our research allows us to estimate the respondents' willingness to trade off democracy for individual income (as well as other societal attributes). We find that, on average, individuals are strongly attached to democracy and a robust welfare state.

Lost support, lost skills: Children's cognitive outcomes following grandparental death.

Objective: This study examines the implications of grandparental death for cognitive skills in middle childhood.

Method: This study uses data from the Future of Families and Child Wellbeing Study (N = 2479) to estimate ordinary least squares regression models of the associations between grandparental death and subsequent cognitive skills among children in middle childhood.

Results: Experiencing a grandparental death between ages 5 and 9 is associated with boys' lower reading, verbal, and math scores at age 9, with associations most notable for Black and Hispanic boys; grandparental death before age 5 has minimal influence on boys' cognitive skills at age 9.

Meta-perception and misinformation.

Research on political misperceptions is flourishing across disciplines. Literature on misinformation susceptibility and political group meta-perceptions have arisen independently, both seeking to understand how inaccurate social beliefs of the first and second order respectively contribute to political polarization. Here we review these literatures and argue for greater integration.

Effects of social distancing policy on labor market outcomes.

US workers receive unemployment benefits if they lose their job, but not for reduced working hours. In alignment with the benefits incentives, we find that the labor market responded to COVID-19 and related closure-policies mostly on the extensive (12 pp outright job loss) margin. Exploiting timing variation in state closure-policies, difference-in-differences (DiD) estimates show, between March 12 and April 12, 2020, employment rate fell by 1.

Effects of a US Supreme Court ruling to restrict abortion rights.

Previous research focused on popular US Supreme Court rulings expanding rights; however, less is known about rulings running against prevailing public opinion and restricting rights. We examine the impact of the Dobbs v. Jackson Women's Health Organization opinion, which overturned Roe v.

Assessing the illegal hunting of native wildlife in China.

Illegal harvesting and trading of wildlife have become major threats to global biodiversity and public health. Although China is widely recognized as an important destination for wildlife illegally obtained abroad, little attention has been given to illegal hunting within its borders. Here we extracted 9,256 convictions for illegal hunting from a nationwide database of trial verdicts in China spanning January 2014 to March 2020.

Physician-patient race-match reduces patient mortality.

This paper assesses the impacts of physician-patient race-match, especially Black patients paired with Black physicians, on patient mortality. We draw on administrative data from Florida, linking hospital encounters from mid-2011 through 2014 to information from the Florida Physician Workforce Survey. Focusing on uninsured patients experiencing unscheduled hospital admissions who are conditionally randomly assigned to physicians, we find that physician-patient race-match for Black patients reduces the likelihood of within-hospital mortality by 0.

Analysis of the impact of COVID-19 pandemic and response on routine childhood vaccination coverage and equity in Northern Nigeria: a mixed methods study.

Background: Based on 2021 data, Nigeria had the second largest number of zero-dose children globally estimated at over 2.25 million, concentrated in the northern part of the country due to factors some of which are sociocultural. This study analysed the impact of the COVID-19 pandemic and response on childhood vaccination in Northern Nigeria.

Parameters, practices, and preferences for regulatory review of emerging biotechnology products in food and agriculture.

This paper evaluates the U.S. regulatory review of three emerging biotechnology products according to parameters, practices, and endpoints of assessments that are important to stakeholders and publics.

Using Natural Language Processing to Construct a National Zoning and Land Use Database.

In the United States, zoning and land use policies have been linked to high housing costs and residential segregation. Yet almost all zoning and land use data come from a handful of cross-sectional surveys, which are costly, time intensive, subject to low response rates and measurement error and are quickly dated. As an alternative, we construct the National Zoning and Land Use Database using natural language processing techniques on publicly available administrative data.

PET-measured human dopamine synthesis capacity and receptor availability predict trading rewards and time-costs during foraging.

Foraging behavior requires weighing costs of time to decide when to leave one reward patch to search for another. Computational and animal studies suggest that striatal dopamine is key to this process; however, the specific role of dopamine in foraging behavior in humans is not well characterized. We use positron emission tomography (PET) imaging to directly measure dopamine synthesis capacity and D and D receptor availability in 57 healthy adults who complete a computerized foraging task.

The neglected role of abandoned cropland in supporting both food security and climate change mitigation.

Despite the looming land scarcity for agriculture, cropland abandonment is widespread globally. Abandoned cropland can be reused to support food security and climate change mitigation. Here, we investigate the potentials and trade-offs of using global abandoned cropland for recultivation and restoring forests by natural regrowth, with spatially-explicit modelling and scenario analysis.

Cognitive Health Disparities by Race and Ethnicity: The Role of Occupational Complexity and Occupational Status.

Disparities in older age cognitive health by race/ethnicity persist even after controlling for individual-level indicators of childhood and adult socioeconomic status. High levels of labor market segregation mean that Black and Latino workers, on average, may not have the same exposure to jobs involving complex work with data and people as their White counterparts, aspects of work that appear to be protective of older adult cognition. However, the role of variation in exposure to occupational complexity by race/ethnicity remains understudied as an explanation for cognitive disparities at older ages.

The role of civil society organizations (CSOs) in the COVID-19 response across the Global South: A multinational, qualitative study.

Despite receiving less attention than high-income countries, low- and middle-income countries (LMICs) experienced more than 85% of global excess deaths during the first two years of the COVID-19 pandemic. Due to the unprecedented speed and scale of the COVID-19 pandemic, which placed large demands on government capacity, many LMICs relied on civil society organizations (CSOs) to assist in implementing COVID-19 response programs. Yet few studies have examined the critical role CSOs played in mitigating the effects of the COVID-19 pandemic in low resource settings.

Assessing shorebird mortalities due to razor clam aquaculture at key migratory stopover sites in southeastern China.

Aquaculture can provide foraging habitat for birds, but it can also result in intentional and accidental mortality. We examined an overlooked conflict between razor clam (Sinonovacula spp.) aquaculture and declining shorebirds in southeastern China's Fujian and Zhejiang provinces.
