Improving Computer Vision Interpretability: Transparent Two-Level Classification for Complex Scenes

Wed, 22 Apr 2026 00:00:00 +0000

Abstract Treating images as data has become increasingly popular in political science. While existing classifiers for images reach high levels of accuracy, it is difficult to systematically assess the visual features on which they base their classification. This paper presents a two-level classification method that addresses this transparency problem. At the first stage, an image segmenter detects the objects present in the image and a feature vector is created from those objects. In the second stage, this feature vector is used as input for standard machine learning classifiers to discriminate between images. We apply this method to a new dataset of more than 140,000 images to detect which ones display political protest. This analysis demonstrates three advantages to this paper’s approach. First, identifying objects in images improves transparency by providing human-understandable labels for the objects shown on an image. Second, knowing these objects enables analysis of which...

A causal approach for detecting team-level momentum in NBA games

Wed, 22 Apr 2026 00:00:00 +0000

This paper provides new evidence that team-level momentum exists in the National Basketball Association (NBA). The existence of momentum is one of the most prominent and longstanding questions in sports analytics. But for all its importance to announcers, coaches, and players, existing literature has found little evidence of momentum in professional basketball. This paper exploits a natural experiment in the flow of basketball games: television (TV) timeouts. Since TV timeouts occur at points exogenous to momentum, they enable the measurement of the effect of pauses in the game separate from the effect of strategy changes. We find TV timeouts cause an 11.2% decline in the number of points that the team with momentum subsequently scores. This effect is robust to the size of a run, substitutions, and game context. This result has far reaching implications in basketball strategy and the understanding of momentum in sports more broadly.

Digitizing and Generating Social Conflict Data with Artificial Intelligence

Wed, 22 Apr 2026 00:00:00 +0000

The difficulty of collecting social conflict data has caused its study to focus on recent events predominantly in the West. This paper shows how to use artificial intelligence to generate social conflict data regardless of language, location, or date. Digitizing tertiary books, lightly cleaning their text representation, and submitting that text to a large language model (LLM) produces accurate date, location, and event descriptions. These capabilities and results are demonstrated with books on Latin America after 1492, Imperial Russia, and Tokugawa Japan. Using LLMs requires a larger fixed cost than working a team of research assistants, but it produces results more quickly for most sources. It is less accurate for the Tokugawa Japan source; whether it or human translation is cheaper depends on the cost of correcting the LLM’s work. These results represent the floor of accuracy for artificial intelligence, suggesting researchers should soon use it for creating social conflict...

Vehicle access and falling transit ridership: evidence from Southern California

Fri, 16 Jan 2026 00:00:00 +0000

We examine pre-COVID declines in transit ridership, using Southern California as a case study. We first illustrate Southern California’s unique position in the transit landscape: it is a large transit market that demographically resembles a small one. We then draw on administrative data, travel diaries, rider surveys, accessibility indices, and Census microdata for Southern California, and demonstrate a strong association between rising private vehicle access, particularly among the populations most likely to ride transit, and falling transit use. Because we cannot control quantitatively for the endogeneity between vehicle acquisition and transit use, our results are not causal. Nevertheless, the results strongly suggest that increasing private vehicle access helped depress transit ridership. Given Southern California’s similarity to most US transit markets, we conclude that vehicle access may have played a role in transit losses across the US since 2000.

Taken at face value: Emotion expression and protest dynamics

Wed, 22 Oct 2025 00:00:00 +0000

Understanding the role of emotions in protest is a growing field of research, but existing research does not address the role of emotions once protests start. By applying computer vision models to the expressed emotions of 37,558 faces in 7,824 geolocated protest images across twelve protest waves in ten countries, this article contributes to the study of emotions and protest. Most importantly, it measures emotions within protest waves, not before them. It also investigates emotions’ temporal effects, measures multiple emotions simultaneously, connects emotions directly to actual protests, and analyzes data across multiple countries. The results suggest that anger, disgust, fear, happiness, sadness, and surprise occur simultaneously throughout a protest, though happiness peaks on the first day. Emotions sometimes correlate with protest size in unexpected directions, and the coefficient signs differ by country. The most consistent finding is that models without lagged terms outperform...

State of the BART: Analyzing the Determinants of Bay Area Rapid Transit Use in the 2010s

Tue, 30 Sep 2025 00:00:00 +0000

Peaking on public transit—the concentration of ridership in peak times and directions into and out of central areas—has waxed in the U.S. over the past century, as public transit has lost more mode share at off-peak times, in off-peak directions, and among non-commute trips. A notable pre-pandemic manifestation of this chronic problem was on Bay Area Rapid Transit, the San Francisco Bay Area’s regional heavy rail system. While BART staved off an absolute ridership decline longer than most American transit operators in the mid- and late-2010s, it did so almost entirely due to peak gains in riders offsetting off-peak losses. As a result, the system experienced worsening passenger crowding at some times and places, expanding underutilization of capacity at many others, and the prospect of enormous expenditures to accommodate rising transbay passenger demand. To examine the factors driving transit use in the 2010s, we model peak and off-peak BART trips as a function of station...

Transit's Financial Prognosis: Findings from a Survey of U.S. Transit Systems during the COVID-19 Pandemic

Tue, 30 Sep 2025 00:00:00 +0000

The COVID-19 pandemic occasioned significant financial distress and uncertainty for many U.S. transit operators. In the face of this crisis, the federal government provided substantial supplemental operating support. To understand how this fiscal turmoil and relief have affected U.S. transit systems, we conducted two nationwide surveys of transit agency staff in 2020 and 2021-2022. While pandemic-induced financial shortfalls affected service in 2020, with capital projects delayed too, these effects became much more muted by 2021/2022. Most systems reported moderate to substantial increases in federal funding during the pandemic, more so than other funding categories. However, nearly half foresee financial shortfalls once federal relief funding expires. Agencies with higher pre-pandemic ridership and farebox recovery are particularly affected by fare revenue losses and more likely to anticipate shortfalls. In the near term, difficulty hiring and retaining front-line workers was...

Sex or sexuality? Analyzing the division of labor and travel in gay, lesbian, and straight households

Wed, 9 Apr 2025 00:00:00 +0000

People make tradeoffs between paid and unpaid labor, and in straight households women typically do the lion's share of unpaid labor, including household-serving travel. Nearly all of the previous research on this topic is limited to married heterosexual households with children, a surprisingly small and shrinking portion of the population. Using pooled data from the 2003–12 American Time Use Surveys, we explore how household-serving labor and travel vary across household types in the U.S. We examine the paid and unpaid labor tradeoffs made by partnered same-sex couples with and without children, and find that their division of paid and unpaid labor, as well as household-serving travel such as chauffeuring children, occupies a statistical middle ground between straight men and women. This suggests that the gendered nature of paid and unpaid work and travel is muted in the absence of a two-sex household structure, though some gendered differences persist.

Redefining expectations for urban water supply systems to fight wildfires

Three major implications stemming from the water supply narratives around the Los Angeles fires have emerged: the need for greater infrastructure resilience, considering the uneven costs of new expectations, and combating disinformation.

Terra Incognita : California Transit Agency Perspectives on Demand, Service, and Finance in the Age of COVID-19

Thu, 13 Feb 2025 00:00:00 +0000

The COVID-19 pandemic upended transit use, finance, and management. To investigate these effects two years into the pandemic, we conducted 21 semi-structured interviews with senior managers at transit agencies in the most populous U.S. state, California. We found that the pandemic generated many operational and managerial challenges for transit agencies. Ridership plummeted, then slowly recovered, but is still well below pre-pandemic levels at most agencies. Commuter trips to and from major job centers were especially slow to return. In response to decreased demand, public health concerns, and uncertain finances, many agencies cut services and spending early on. As a result, fare revenues declined, in some cases precipitously. However, federal pandemic relief funds proved essential in filling budgetary gaps, stabilizing finances, preventing layoffs, and maintaining services. Other transit subsidies mostly bounced back robustly. Our interviews suggest that, though California transit...

Inability to Access Needed Medical Care Among Asian American, Native Hawaiian, and Pacific Islander Medicaid Enrollees

Tue, 28 Jan 2025 00:00:00 +0000

We examined self-reported inability to access to needed medical care and reasons for not accessing medical care among US-representative adult Medicaid enrollees, disaggregated across 10 Asian American, Native Hawaiian, and Pacific Islander ethnic groups. Chinese (-4.54 percentage points [PP], P < .001), Other Asian (-4.42 PP, P < .001), and Native Hawaiian (-4.36 PP, P < .001) enrollees were significantly less likely to report being unable to access needed medical care compared with non-Hispanic White enrollees. The most common reason reported was that a health plan would not approve, cover, or pay for care. Mitigating inequities may require different interventions specific to certain ethnic groups.

Housing Insecurity Among Latinxs

Wed, 13 Nov 2024 00:00:00 +0000

Abstract Latinxs are vulnerable to experiencing housing insecurity and less likely to receive public benefits, such as health insurance, which can impact a household’s economic resources. We inform homelessness prevention by examining the association of social risks and healthcare access with housing insecurity for Latinxs. Our sample consisted of 120,362 participants under the age of 65, of which 17.3% were Latinx. Weighted chi-squared tests and logistic regression were used to examine predictors of housing insecurity. Housing insecurity was measured as worry about paying for housing. Latinxs were almost twice as likely as non-Latinxs to worry about paying for housing. Excellent/fair health status, health service use, and having health insurance decreased the likelihood of housing insecurity for Latinxs. Access to health insurance, regardless of citizenship status, and use of preventative healthcare to maintain good health can be protective against housing insecurity.

Using a Modified Delphi Approach to Explore California's Possible Transportation and Land Use Futures

Wed, 2 Oct 2024 00:00:00 +0000

Many methods exist for engaging experts in interactive groups to explore, clarify, and/or decide on various issues. In an investigation of four possible future scenarios concerning transportation and land use in California, we developed a novel “hybrid policy Delphi” method for use with a panel of 18 experts. We applied it to explore the policies and practices that would likely lead to each of the four scenarios and the consequences that would result from them. Through our process, panel members discussed and reflected on the scenarios in multiple ways. The scenario they considered most desirable they also deemed least likely to occur, and they foresaw the likely trajectory of California transportation and land use leading to less desirable scenarios. Our mix of discussion and questionnaires traded the benefit of anonymity for the benefit of exploratory, interactive discussion. In addition, our use of surveys before and after meetings allowed us to track changes in panel opinion...

How State and Protester Violence Affect Protest Dynamics.

Mon, 16 Sep 2024 00:00:00 +0000

How do state and protester violence affect whether protests grow or shrink? Previous research finds conflicting results for how violence affects protest dynamics. This article argues that expectations and emotions should generate an n-shaped relationship between the severity of state repression and changes in protest size the next day. Protester violence should reduce the appeal of protesting and increase the expected cost of protesting, decreasing subsequent protest size. Since testing this argument requires precise measurements, a pipeline is built that applies convolutional neural networks to images shared in geolocated tweets. Continuously valued estimates of state and protester violence are generated per city-day for 24 cities across five countries, as are estimates of protest size and the age and gender of protesters. The results suggest a solution to the repression-dissent puzzle and join a growing body of research benefiting from the use of social media to understand subnational...

How social networks affect the repression-dissent puzzle

Sat, 14 Sep 2024 00:00:00 +0000

Scholars have offered multiple theoretical resolutions to explain inconsistent findings about the relationship of state repression and protests, but this repression-dissent puzzle remains unsolved. We simulate the spread of protest on social networks to suggest that the repression-dissent puzzle arises from the nature of statistical sampling. Even though the paper's simulations construct repression so it can only decrease protest size, the strength of repression sometimes correlates with a decrease, increase, or no change in protest size, regardless of the type of network or sample size chosen. Moreover, the results are most contradictory when the repression rate most closely matches that observed in real-world data. These results offer a new framework for understanding state and protester behavior and suggest the importance of collecting network data when studying protests.

"Whose help is on the way?": The importance of individual police officers in law enforcement outcomes.

Wed, 28 Aug 2024 00:00:00 +0000

Police discretion has large potential consequences for public trust and safety; however, little is known about the extent of this discretion. I show that arrests critically depend on which officer responds to a 911 call; 1 standard deviation increase in officer arrest propensity raises arrest likelihood by 40%. High arrest officers are more likely to be white and have less experience. I find mixed evidence that arrest propensity is related to arrest quality. High arrest officers use force more often and make more low-level arrests, while they also have a higher share of low-level arrests that result in conviction.

Undocumented Latino Immigrants and the Latino Health Paradox

Mon, 5 Aug 2024 00:00:00 +0000

INTRODUCTION: Despite having worse healthcare access and other social disadvantages, immigrants have, on average, better health outcomes than U.S.-born individuals. For Latino immigrants, this is known as the Latino health paradox. It is unknown whether this phenomenon applies to undocumented immigrants. METHODS: This study used restricted California Health Interview Survey data from 2015 to 2020. Data were analyzed to test the relationships between citizenship/documentation status and physical and mental health among Latinos and U.S.-born Whites. Analyses were stratified by sex (male/female) and length of U.S. residence (<15 years/>= 15 years). RESULTS: Undocumented Latino immigrants had lower predicted probabilities of reporting any health condition, asthma, and serious psychological distress and had a higher probability of overweight/obesity than U.S.-born Whites. Despite having a higher probability of overweight/obesity, undocumented Latino immigrants did not have probabilities...

Renter Nonpayment and Landlord Response: Evidence From COVID-19

Mon, 1 Jul 2024 00:00:00 +0000

How renters respond to economic hardship, and how landlords respond when tenants fail to make rent, are understudied questions, owing largely to limited data. We use experiences from the COVID-19 pandemic to begin answering these questions. Drawing on both new census data and two original surveys of renters in Los Angeles County, we test nine hypotheses about the sources of renter distress and landlord reactions to it. We find that lost work and lost income are the primary drivers of missed or late payments. Most tenants who fell behind entered into repayment plans with their landlords. Eviction threats were uncommon but increased as the pandemic persisted. Landlords were more likely to threaten eviction as tenants fell further behind, and smaller landlords were more likely than larger ones to cut tenant services and threaten or initiate evictions. Our evidence suggests that government income support helped tenants pay rent and thus helped stave off eviction threats. We also find...

Were small businesses more likely to permanently close in the pandemic?

Mon, 17 Jun 2024 00:00:00 +0000

Abstract Previous estimates indicate that COVID-19 led to a large drop in the number of operating businesses operating early in the pandemic, but surprisingly little is known on whether these shutdowns turned into permanent closures and whether small businesses were disproportionately hit. This paper provides the first analysis of permanent business closures using confidential administrative firm-level panel data covering the universe of businesses filing sales taxes from the California Department of Tax and Fee Administration. We find large increases in closure rates in the first two quarters of 2020, but a strong reversal of this trend in the third quarter of 2020. The increase in closures rates in the first two quarters of the pandemic was substantially larger for small businesses than large businesses, but the rebound in the third quarter was also larger. The disproportionate closing of small businesses led to a sharp concentration of market share among larger businesses as...

Three’s a crowd? Examining evolving public transit crowding standards amidst the COVID-19 pandemic

Fri, 7 Jun 2024 00:00:00 +0000

The COVID-19 pandemic dramatically affected public transit systems around the globe. Because transit systems typically move many people closely together on buses and trains, public health guidance demanded that riders should keep a distance of about two meters to others changed the definition of “crowding” on transit in 2020. Accordingly, this research examines how U.S. public transit agencies responded to public health guidance that directly conflicted with their business model. To do this, we examined published crowding standards before the COVID-19 pandemic for a representative sample of 200 transit systems, including whether they started or changed their published standards during the pandemic, as well as the reasons whether agencies publicize such standards at all. We present both descriptive statistics and regression model results to shed light on the factors associated with agency crowding standards. We find that 56% of the agencies surveyed published crowding standards...

Making Communities More Visible: Equity‐Centered Data to Achieve Health Equity

Thu, 6 Jun 2024 00:00:00 +0000

Policy Points Despite decades of research exposing health disparities between populations and communities in the US, health equity goals remain largely unfulfilled. We argue these failures call for applying an equity lens in the way we approach data systems, from collection and analysis to interpretation and distribution. Hence, health equity requires data equity. There is notable federal interest in policy changes and federal investments to improve health equity. With this, we outline the opportunities to align these health equity goals with data equity by improving the way communities are engaged and how population data are collected, analyzed, interpreted, made accessible, and distributed. Policy priority areas for data equity include increasing the use of disaggregated data, increasing the use of currently underused federal data, building capacity for equity assessments, developing partnerships between government and community, and increasing data accountability to the public.

Built out cities? A new approach to measuring land use regulation

Sun, 28 Apr 2024 00:00:00 +0000

We introduce a new way to measure the stringency of housing regulation. Rather than a standard regulatory index or a single aspect of regulation like Floor Area Ratio, we draw on cities' self-reported estimates of their total zoned capacity for new housing. This measure, available to us as a result of state legislation in California, offers a more accurate way to assess local antipathy toward new housing, and also offers a window into how zoning interacts with existing buildout. We show, in regressions analyzing new housing permitting, that our measure has associations with new supply that are as large or larger than conventional, survey-based indexes of land use regulation. Moreover, unbuilt zoning capacity interacts with rent to predict housing production in ways conventional measures do not. Specifically, interacting our measure with rent captures the interplay of regulation and demand: modest deregulation in high-demand cities is associated with substantially more housing...

Feminist retroviruses to white Sharia: Gender “science fan fiction” on 4Chan

Wed, 27 Mar 2024 00:00:00 +0000

This article demonstrates-based on an interpretive discourse analysis of three types of memes (Rabid Feminists, Women's Bodies, Policy Ideas) and secondary thread discourse on 4chan's "Politically Incorrect" discussion board-two key findings: (1) the existence of a gendered hate based scientific discourse, "science fan fiction," in online spaces and (2) how gender "science fan fiction" is an outcome of the male supremacist cosmology, by producing and justifying resentment against white women as being both inherently untrustworthy (politically, sexually, intellectually) and dangerous. This perspective-which combines hatred and distrust of women with white nationalist anxieties about demographic shifts, racial integrity, and sexuality-then motivates misogynist policy ideas including total domination of women or their removal. 4chan users employ this discourse to "scientifically" substantiate claims of white male supremacy, the fundamental untrustworthiness of white women, and to...

Functional characterization of age-dependent p16 epimutation reveals biological drivers and therapeutic targets for colorectal cancer

Fri, 19 Jan 2024 00:00:00 +0000

BackgroundMethylation of the p16 promoter resulting in epigenetic gene silencing—known as p16 epimutation—is frequently found in human colorectal cancer and is also common in normal-appearing colonic mucosa of aging individuals. Thus, to improve clinical care of colorectal cancer (CRC) patients, we explored the role of age-related p16 epimutation in intestinal tumorigenesis.MethodsWe established a mouse model that replicates two common genetic and epigenetic events observed in human CRCs: Apc mutation and p16 epimutation. We conducted long-term survival and histological analysis of tumor development and progression. Colonic epithelial cells and tumors were collected from mice and analyzed by RNA sequencing (RNA-seq), quantitative PCR, and flow cytometry. We performed single-cell RNA sequencing (scRNA-seq) to characterize tumor-infiltrating immune cells throughout tumor progression. We tested whether anti-PD-L1 immunotherapy affects overall survival of tumor-bearing mice and whether...

The Self-Fulfilling Process of Clinical Race Correction: The Case of Eighth Joint National Committee Recommendations

Wed, 17 Jan 2024 00:00:00 +0000

There is growing attention to how unfounded beliefs about biological differences between racial groups affect biomedical research and health care, in part, through race adjustment in clinical tools. We develop a case study of the Eighth Joint National Committee (JNC 8)'s 2014 Evidence-Based Guideline for the Management of High Blood Pressure in Adults, which recommends a distinct initial hypertension treatment for Black versus nonblack patients. We analyze the historical context, study design, and racialized findings of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) that informed development of the guideline. We argue that ALLHAT's racialized outcomes emanated from a poor and artificial study design and analysis weakened by implicit assumptions about race as biological. We show that the acceptance and utilization of ALLHAT for race correction arises from its historical context within the "inclusion-and-difference paradigm" and its indication...

What explains gender inequalities in HIV/AIDS prevalence in sub-Saharan Africa? Evidence from the demographic and health surveys

Sun, 24 Dec 2023 00:00:00 +0000

BackgroundWomen are disproportionally affected by human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in sub-Saharan Africa (SSA). The determinants of gender inequality in HIV/AIDS may vary across countries and require country-specific interventions to address them. This study aimed to identify the socio-demographic and behavioral characteristics underlying gender inequalities in HIV/AIDS in 21 SSA countries.MethodsWe applied an extension of the Blinder-Oaxaca decomposition approach to data from Demographic and Health Surveys and AIDS Indicator Surveys to quantify the differences in HIV/AIDS prevalence between women and men attributable to socio-demographic factors, sexual behaviours, and awareness of HIV/AIDS. We decomposed gender inequalities into two components: the percentage attributable to different levels of the risk factors between women and men (the “composition effect”) and the percentage attributable to risk factors having differential effects...

Zoning, Land Use, and the Reproduction of Urban Inequality

Fri, 22 Dec 2023 00:00:00 +0000

Zoning determines what can be built where, and is ubiquitous in the United States. Low-density residential zoning predominates in US cities far more than in other countries, limiting housing opportunities for those who cannot afford large homes. These zoning regulations have racist and classist origins, make housing more expensive, and reinforce segregation patterns. While sociologists study these consequences of zoning, and other causes of unaffordable housing and segregation, they rarely examine zoning itself. This article argues for a sociological research agenda on zoning and land use.

How do hospitals respond to input regulation? Evidence from the California nurse staffing mandate

Mon, 18 Dec 2023 00:00:00 +0000

Mandated minimum nurse-to-patient ratios have been the subject of active debate in the U.S. for over twenty years and are under legislative consideration today in several states and at the federal level. This paper uses the 1999 California nurse staffing mandate as an empirical setting to estimate the causal effects of minimum ratios on hospitals. Minimum ratios led to a 58 min increase in nursing time per patient day and 9 percent increase in the wage bill per patient day in the general medical/surgical acute care unit among treated hospitals. Hospitals responded on several margins: increased use of lower-licensed and younger nurses, reduced capacity by 16 beds (14 percent), and increased bed utilization rates by 0.045 points (8 percent). Using administrative data on discharges for acute myocardial infarction (AMI), I find a significant reduction in length of stay (5 percent) and no effect on the 30-day all-cause readmission rate. The null effect on readmissions suggests that...

Zoning and affordability: A reply to Rodríguez-Pose and Storper

Mon, 11 Dec 2023 00:00:00 +0000

Would increasing allowable housing densities in expensive cities generate more housing construction and make housing more affordable? In a provocative article, Andrés Rodríguez-Pose and Michael Storper survey the evidence and answer no. Restrictions on housing density, they contend, do not substantially influence housing production or price. They further argue that allowing more density in growing metropolitan areas would only improve housing outcomes for the affluent, and most likely harm the poor. We take issue with both of these contentions. While uncertainties remain in the study of housing prices and land use regulation, neither theory nor evidence warrant dispensing with zoning reform, or concluding that it could only be regressive. Viewed in full, the evidence suggests that increasing allowable housing densities is an important part of housing affordability in expensive regions.

Pandemic transit: examining transit use changes and equity implications in Boston, Houston, and Los Angeles

Sat, 2 Dec 2023 00:00:00 +0000

While the COVID-19 pandemic upended many aspects of life as we knew it, its effects on U.S. public transit were especially dramatic. Many former transit commuters began to work from home or switched to traveling via private vehicles. But for those who continued to work outside the home and could not drive—who were more likely low-income and Black or Hispanic—transit remained an important means of mobility. However, most transit agencies reduced service during the first year of the pandemic, reflecting reduced ridership demand, increasing costs, and uncertain budgets. To analyze the effects of the pandemic on transit systems and their users, we examine bus ridership changes by neighborhood in Boston, Houston, and Los Angeles from 2019 to 2020. Combining aggregated stop-level boarding data, passenger surveys, and census data, we identify associations between shifting travel patterns and neighborhoods. We find that early in the pandemic, neighborhoods with more poor and non-white...

Transit Blues in the Golden State: Regional transit ridership trends in California

Wed, 1 Nov 2023 00:00:00 +0000

Public investment in transit increased following the Great Recession, yet transit use nationally mostly fell, even prior to the 2020 pandemic. We investigate this troubling disjuncture by comparing transit ridership trends during the 2010s in two of America’s largest regions: Greater Los Angeles and the San Francisco Bay Area. While both California regions lost transit riders, we see substantial differences in the scale, timing, geography, and modes of these declines. In the LA area, ridership fell longer and further, spread more across routes, times, and sub-regions and concentrated on the region’s dominant operator. In both regions, increasing auto access appears to have played a central role, albeit in different ways. Greater LA saw increased automobile ownership, particularly among high-propensity transit riders. In the Bay Area, as jobs and housing have dispersed, ridehail services like Lyft and Uber may have eroded non-commute transit use.

Extremely low-income households, housing affordability and the Great Recession

Tue, 19 Sep 2023 00:00:00 +0000

The effects of the Great Recession on housing equity and homeownership have been well-documented. However, we know little about how rental households fared and the efficacy of housing subsidies in addressing affordability gaps. This paper examines the extent to which rental housing became less affordable for Extremely Low-Income (ELI) households - those earning less than 30% of the Area Median Income (AMI). I then run regression models to determine the local characteristics most strongly associated with larger affordability gaps, with a focus on whether housing subsidies are effective at combating such gaps. Rental affordability gaps became more pronounced during the Great Recession. In nearly 70% of the counties in my sample, there was an increase from 2007 to 2010 in the number of ELI households per affordable rental unit. Across the country, the increase was 17%, a dramatic increase in only three years. There is considerable variation across the country, with acute affordability...

Employment proximity and outcomes for Moving to Opportunity families

Tue, 19 Sep 2023 00:00:00 +0000

The Moving to Opportunity for Fair Housing Demonstration (MTO) randomly assigned housing vouchers to public housing residents in an experimental test of the effect of neighborhood and location on household outcomes. In terms of adult employment outcomes, the 2 treatment groups did not significantly differ from the control group. We use MTO data to examine whether spatial proximity to jobs and job growth explains this lack of treatment effect. We first estimate differences in access to jobs and job growth for the 3 MTO groups. We then use 2-stage least squares models to test relationships between employment accessibility and 2 key outcomes: employment status and earned income. We find that employment accessibility declined for all groups, and these declines were strongest for the 2 treatment groups. However, our results show essentially no effect of employment proximity on earnings or employment status for MTO participants.

Decreasing Black-White Disparities in Colorectal Cancer Incidence and Stage at Presentation in the United States

Mon, 18 Sep 2023 00:00:00 +0000

Background: There are long-standing black-white disparities in colorectal cancer incidence and outcomes in the United States. Incidence and stage at diagnosis reflect the impact of national efforts directed at colorectal cancer prevention and control. We aimed to evaluate trends in black-white disparities in both indicators over four decades to inform the future direction of prevention and control efforts.Methods: We used Surveillance, Epidemiology, & End Results (SEER) data to identify whites and blacks with histologically confirmed colorectal cancer from January 1, 1975 through December 31, 2012. We calculated the age-adjusted incidence and the proportion of cases presenting in late stage by race and year. We then calculated the annual percentage change (APC) and average APC for each indicator by race, examined changes in indicators over time, and calculated the incidence disparity for each year.Results: There were 440,144 colorectal cancer cases from...

Daytime Locations in Spatial Mismatch: Job Accessibility and Employment at Reentry From Prison

Mon, 18 Sep 2023 00:00:00 +0000

Individuals recently released from prison confront many barriers to employment. One potential obstacle is spatial mismatch—the concentration of low-skilled, nonwhite job-seekers within central cities and the prevalence of relevant job opportunities in outlying areas. Prior research has found mixed results about the importance of residential place for reentry outcomes. In this article, we propose that residential location matters for finding work, but this largely static measure does not capture the range of geographic contexts that individuals inhabit throughout the day. We combine novel, real-time GPS information on daytime locations and self-reported employment collected from smartphones with sophisticated measures of job accessibility to test the relative importance of spatial mismatch based on residence and daytime locations. Our findings suggest that the ability of low-skilled, poor, and urban individuals to compensate for their residential deficits by traveling to job-rich...

Are Unequal Policies in Pre-Exposure Prophylaxis Uptake Needed to Improve Equality? An Examination Among Men Who Have Sex with Men in Los Angeles County

Sat, 9 Sep 2023 00:00:00 +0000

Racial and ethnic minority men who have sex with men (MSM) are disproportionately affected by HIV/AIDS in Los Angeles County (LAC), an important epicenter in the battle to end HIV. We examine tradeoffs between effectiveness and equality of pre-exposure prophylaxis (PrEP) allocation strategies among different racial and ethnic groups of MSM in LAC and provide a framework for quantitatively evaluating disparities in HIV outcomes. To do this, we developed a microsimulation model of HIV among MSM in LAC using county epidemic surveillance and survey data to capture demographic trends and subgroup-specific partnership patterns, disease progression, patterns of PrEP use, and patterns for viral suppression. We limit analysis to MSM, who bear most of the burden of HIV/AIDS in LAC. We simulated interventions where 3000, 6000, or 9000 PrEP prescriptions are provided annually in addition to current levels, following different allocation scenarios to each racial/ethnic group (Black, Hispanic,...

Closing the Gap: Expanding Public Health Insurance Eligibility to Immigrants in Illinois

Wed, 23 Aug 2023 00:00:00 +0000

Immigrants without legal or long-term residency are even more likely to be purposefully excluded from public healthcare or healthcare assistance. Due to the Healthy Illinois campaign and network of health equity-focused organizations, Illinois has made much progress in expanding Medicaid-like healthcare services to all low-income residents in Illinois, regardless of immigration status. Currently, Illinois has three immigrant-focused healthcare programs that are almost functionally identical to federal Medicaid: All Kids (ages 0-18), Health Benefits of Immigrant Seniors (ages 65+), and Health Care for Immigrant Adults (ages 42-64). As a result, immigrants who are federally ineligible for Medicaid between the ages of 0 to 18 and 42+ have access to state healthcare coverage. However, there is a gap in coverage for those ages 19 to 41. Using enrollment data from the Illinois Department of Health and Family Services (HFS) and analyzing interviews with HBIS/A enrollees and healthcare...

Police Force Size and Civilian Race.

Thu, 20 Jul 2023 00:00:00 +0000

We report novel empirical estimates of the race-specific effects of larger police forces in the United States. Each additional police officer abates approximately 0.1 homicides. In per capita terms, effects are twice as large for Black versus White victims. Larger police forces also make fewer arrests for serious crimes, with larger reductions for crimes with Black suspects, implying that police force growth does not increase racial disparities among the most serious charges. At the same time, larger police forces make more arrests for low-level "quality-of-life" offenses, with effects that imply a disproportionate impact for Black Americans.

How White nationalists mobilize genetics: From genetic ancestry and human biodiversity to counterscience and metapolitics

Mon, 10 Jul 2023 00:00:00 +0000

OBJECTIVES: Our aim in this study was to understand how genetics ideas are appropriated and mobilized online toward the political projects of White nationalism and the alt right. Studying three different online venues, we investigated how genetics is used to support racial realism, hereditarianism, and racial hierarchy. We analyzed how these ideas are connected to political and metapolitical projects. In addition, we examined the strategies used to build authority for these interpretations. METHODS: We analyze three online venues in which genetics has been mobilized to advance racial realism and hereditarian explanations of racial differences. These were (a) the use of genetic ancestry tests in online nationalist discussions, (b) blogs and other venues in which the human biodiversity ideas are articulated, (c) activities surrounding the OpenPsych collection of online journals. Ethnographic and interpretive methods were applied to investigate scientific and political meanings of...

Mask images on Twitter increase during COVID-19 mandates, especially in Republican counties

Sat, 8 Jul 2023 00:00:00 +0000

Wearing masks reduces the spread of COVID-19, but compliance with mask mandates varies across individuals, time, and space. Accurate and continuous measures of mask wearing, as well as other health-related behaviors, are important for public health policies. This article presents a novel approach to estimate mask wearing using geotagged Twitter image data from March through September, 2020 in the United States. We validate our measure using public opinion survey data and extend the analysis to investigate county-level differences in mask wearing. We find a strong association between mask mandates and mask wearing—an average increase of 20%. Moreover, this association is greatest in Republican-leaning counties. The findings have important implications for understanding how governmental policies shape and monitor citizen responses to public health crises.

Using Microsimulation Modeling to Inform EHE Implementation Strategies in Los Angeles County

Fri, 7 Jul 2023 00:00:00 +0000

BACKGROUND: Pre-exposure prophylaxis (PrEP) is essential to ending HIV. Yet, uptake remains uneven across racial and ethnic groups. We aimed to estimate the impacts of alternative PrEP implementation strategies in Los Angeles County. SETTING: Men who have sex with men, residing in Los Angeles County. METHODS: We developed a microsimulation model of HIV transmission, with inputs from key local stakeholders. With this model, we estimated the 15-year (2021-2035) health and racial and ethnic equity impacts of 3 PrEP implementation strategies involving coverage with 9000 additional PrEP units annually, above the Status-quo coverage level. Strategies included PrEP allocation equally (strategy 1), proportionally to HIV prevalence (strategy 2), and proportionally to HIV diagnosis rates (strategy 3), across racial and ethnic groups. We measured the degree of relative equalities in the distribution of the health impacts using the Gini index (G) which ranges from 0 (perfect equality, with...

Informing California’s Plan to Enhance HIV Screening in the Ending the HIV Epidemic Initiative

Sat, 24 Jun 2023 00:00:00 +0000

The CDC recommends that everyone have at least one HIV test in their lifetime. However, analyses of California Health Interview Survey data showed that in 2017 only half of Californians had ever received an HIV test. Non-Hispanic Black (64.8%) and Hispanic adults (54.7%) had higher lifetime testing rates than non-Hispanic White adults (48.8%). In multivariable analyses non-Hispanic African American adults had twice and Hispanic adults 1.2 times the odds of lifetime HIV testing as non-Hispanic White adults. The CDC recommends annual HIV testing for higher-risk individuals. Independent of race/ethnicity, heterosexual men with multiple sex partners had lower annual testing rates than other high-risk individuals. Annual testing was unrelated to education level and poverty, but was related to number of doctor visits. HIV screening rates among heterosexual men with multiple partners could be increased by targeting HIV screening to non-medical settings in California's eight Ending the...

Citizen monitoring promotes informed and inclusive forest governance in Liberia

Fri, 23 Jun 2023 00:00:00 +0000

Global forest loss depends on decisions made in the rural, often poor communities living beside the Earth's remaining forests. Governance problems in these forest-edge communities contribute to rapid deforestation and household vulnerability. In coordination with experimental studies in 5 other countries, we evaluate a program that recruits, trains, and deploys citizens to monitor communal forestland in 60 communities in rural Liberia. The year-long intervention is designed to promote more informed and inclusive resource governance, so that that citizens' preferences (and not just leaders' interests) are reflected in forest management. In our control communities, households are uninformed and disengaged; leaders' authority is unchecked. The program both engages and mobilizes community members: households are better informed and participate more in the design and enforcement of rules around forest use. They also report receiving more material benefits from outside investors' activities...

Minority student and teaching assistant interactions in STEM

Thu, 22 Jun 2023 00:00:00 +0000

Graduate student teaching assistants from underrepresented groups may provide salient role models and enhanced instruction to minority students in STEM fields. We explore minority student-TA interactions in an important course in the sciences and STEM - introductory chemistry labs - at a large public university. The uncommon assignment method of students to TA instructors in these chemistry labs overcomes selection problems, and the small and active learning classroom setting with required attendance provides frequent interactions with the TA. We find evidence that underrepresented minority students are less likely to drop courses and are more likely to pass courses when assigned to minority TAs, but we do not find evidence of effects for grades and medium-term outcomes. The effects for the first-order outcomes are large with a decrease in the drop rate by 5.5 percentage points on a base of 6 percent, and an increase in the pass rate of 4.8 percentage points on a base of 93.6...

Cost effectiveness of text messages to reduce methamphetamine use and HIV sexual risk behaviors among men who have sex with men

Sat, 3 Jun 2023 00:00:00 +0000

Methamphetamine use is highly prevalent among gay, bisexual, and other men who have sex with men (MSM) in the United States and has been associated with condomless anal intercourse (CAI), a common route of HIV infection. Text messaging is a very low-cost method of delivery for intervention content. This paper presents a cost-effectiveness analysis of a randomized controlled trial testing three nested methods of text message delivery designed to reduce methamphetamine use and HIV sexual risk behaviors among MSM (Project Tech Support2). From March 2014 to January 2016, 286 non-treatment seeking methamphetamine-using MSM were randomized into one of three study arms: 1) Interactive text message conversations with Peer Health Educators, plus five daily automated, unidirectional theory-based messages, plus a weekly self-monitoring text message assessment (TXT-PHE; n = 94); or, 2) Five daily automated, unidirectional theory-based messages plus a weekly self-monitoring text message assessment...

Child Undernutrition following the Introduction of a Large-Scale Toilet Construction Campaign in India

Fri, 2 Jun 2023 00:00:00 +0000

BACKGROUND: Lack of toilets and the widespread practice of open defecation may contribute to India's large burden of child undernutrition. OBJECTIVES: We examine whether a large national sanitation campaign launched in 2014, the Swachh Bharat Mission (SBM), precedes a reduction in stunting and wasting among under 5-y-old (u5) children in India. METHODS: In this observational study, we used district-level data from before (2013-2014) and after (2015-2016) SBM from 3 national surveys to derive, as our outcomes, the percentage of u5 children per district who are stunted and wasted. We defined our exposures as 1) binary indicator of SBM and 2) percentage of households with toilets per district. Our analytic sample comprised nearly all 640 Indian districts (with ∼1200 rural/urban divisions per district per time point). Linear regression analyses controlled for baseline differences in districts, linear time trends by state, and relevant covariates. RESULTS: Relative to pre-SBM, u5 stunting...

The Impact of Parental and Medical Leave Policies on Socioeconomic and Health Outcomes in OECD Countries: A Systematic Review of the Empirical Literature

Tue, 23 May 2023 00:00:00 +0000

Policy Points: Historically, reforms that have increased the duration of job-protected paid parental leave have improved women's economic outcomes. By targeting the period around childbirth, access to paid parental leave also appears to reduce rates of infant mortality, with breastfeeding representing one potential mechanism. The provision of more generous paid leave entitlements in countries that offer unpaid or short durations of paid leave could help families strike a balance between the competing demands of earning income and attending to personal and family well-being. CONTEXT: Policies legislating paid leave from work for new parents, and to attend to individual and family illness, are common across Organisation for Economic Co-operation and Development (OECD) countries. However, there exists no comprehensive review of their potential impacts on economic, social, and health outcomes. METHODS: We conducted a systematic review of the peer-reviewed literature on paid leave...

Sources of Interactional Problems in a Survey of Racial/Ethnic Discrimination

Mon, 22 May 2023 00:00:00 +0000

Cross-cultural variability in respondent processing of survey questions may bias results from multiethnic samples. We analyzed behavior codes, which identify difficulties in the interactions of respondents and interviewers, from a discrimination module contained within a field test of the 2007 California Health Interview Survey. In all, 553 (English) telephone interviews yielded 13,999 interactions involving 22 items. Multilevel logistic regression modeling revealed that respondent age and several item characteristics (response format, customized questions, length, and first item with new response format), but not race/ethnicity, were associated with interactional problems. These findings suggest that item function within a multi-cultural, albeit English language, survey may be largely influenced by question features, as opposed to respondent characteristics such as race/ethnicity.

Early Evidence From California on Transitions to a Reformed Health Insurance System for Persons Living With HIV/AIDS

Fri, 12 May 2023 00:00:00 +0000

BACKGROUND: Many uninsured people living with HIV/AIDS (PLWHA) will obtain managed health insurance coverage when the Affordable Care Act (ACA) is implemented in January 2014. Since 2011, California has transitioned PLWHA to Medicaid managed care (MMC) and to the Low-Income Health Program (LIHP). OBJECTIVES: To draw lessons for the ACA implementation from the transitions into MMC and the LIHP. METHODS: Surveys about clients and services provided before and after the transition to MMC and the LIHP were sent to 43 HIV service providers. Usable responses were obtained from 18 (42%). RESULTS: Although total client loads were similar in the pre- (January 2011) and posttransition periods (June 2012), many clients transitioned from fee-for-service (FFS) Medicaid to MMC. Over this period, responding agencies served 43.5% fewer PLWHA in FFS Medicaid, whereas the share of PLWHA covered by MMC rose from 16.9% to 55.5%. Managed care covered a smaller number of services than either FFS Medicaid...

Transitioning From Medicaid Disability Coverage to Long-Term Medicare Coverage: The Case of People Living With HIV/AIDS in California.

Wed, 10 May 2023 00:00:00 +0000

Medicaid can serve as a bridge to Medicare coverage for the long-term disabled with sufficient covered work experience. We perform multinomial logistic regression on 2007-2010 Medicare and Medicaid claims data to examine transitions to Medicare for people living with HIV/AIDS (PLWHA) in California who had Medicaid coverage in 2007. We find only 16% had obtained Medicare coverage by 2010. African-Americans, women, individuals with schizophrenia diagnoses, alcohol or substance abuse disorders, and any physical comorbidity were significantly less likely than others to obtain Medicare (p < 0.001). This study contributes new information on the impact of eligibility requirements for Medicare long-term disability insurance for PLWHA. About one-third of PLWHA under age 65 are covered by Medicaid. Many PLWHA get stuck in Medicaid because their disability prevents them from obtaining the additional employment experience needed to qualify for Medicare.

Investing in the foundation of sustainable development: pathways to scale up for early childhood development

Wed, 10 May 2023 00:00:00 +0000

Building on long-term benefits of early intervention (Paper 2 of this Series) and increasing commitment to early childhood development (Paper 1 of this Series), scaled up support for the youngest children is essential to improving health, human capital, and wellbeing across the life course. In this third paper, new analyses show that the burden of poor development is higher than estimated, taking into account additional risk factors. National programmes are needed. Greater political prioritisation is core to scale-up, as are policies that afford families time and financial resources to provide nurturing care for young children. Effective and feasible programmes to support early child development are now available. All sectors, particularly education, and social and child protection, must play a role to meet the holistic needs of young children. However, health provides a critical starting point for scaling up, given its reach to pregnant women, families, and young children. Starting...

The impact of two Los Angeles County Teen Courts on youth recidivism: comparing two informal probation programs

Wed, 3 May 2023 00:00:00 +0000

ObjectiveThis study sought to examine the impact of two Teen Courts operating in Los Angeles County, a juvenile justice system diversion program in which youths are judged by their peers and given restorative sentences to complete during a period of supervision.MethodsA quasi-experimental design was used to compare youths who participated in Teen Courts (n = 112) to youths who participated in another diversion program administered by the Probation Department (the 654 Contract program) (n = 194). Administrative data were abstracted from the probation records for all youths who participated in these programs between January 1, 2012 and June 20, 2014. Logistic and survival models were used to examine differences in recidivism, measured as whether the minor had any subsequent arrest or arrests for which the charge was filed.ResultsComparison group participants had higher rates of recidivism than Teen Court participants, after controlling for age, gender, race/ethnicity, and risk level....

How Does Household Income Affect Child Personality Traits and Behaviors?

Mon, 1 May 2023 00:00:00 +0000

We examine the effects of a quasi-experimental unconditional household income transfer on child emotional and behavioral health and personality traits. Using longitudinal data, we find that there are large beneficial effects on children's emotional and behavioral health and personality traits during adolescence. We find evidence that these effects are most pronounced for children who start out with the lowest initial endowments. The income intervention also results in improvements in parental relationships which we interpret as a potential mechanism behind our findings.

Determinants of Coverage Decisions in Health Insurance Marketplaces: Consumers' Decision‐Making Abilities and the Amount of Information in Their Choice Environment

Sat, 15 Apr 2023 00:00:00 +0000

OBJECTIVE: To investigate the determinants and quality of coverage decisions among uninsured choosing plans in a hypothetical health insurance marketplace. STUDY SETTING: Two samples of uninsured individuals: one from an Internet-based sample comprised largely of young, healthy, tech-savvy individuals (n = 276), and the other from low-income, rural Virginians (n = 161). STUDY DESIGN: We assessed whether health insurance comprehension, numeracy, choice consistency, and the number of plan choices were associated with participants' ability to choose a cost-minimizing plan, given their expected health care needs (defined as choosing a plan costing no more than $500 in excess of the total estimated annual costs of the cheapest plan available). DATA COLLECTION: Primary data were collected using an online questionnaire. PRINCIPAL FINDINGS: Uninsured who were more numerate showed higher health insurance comprehension; those with more health insurance comprehension...

Spatial Concentration and Spillover: Eviction Dynamics in Neighborhoods of Los Angeles, California, 2005–2015

Tue, 28 Mar 2023 00:00:00 +0000

The lack of sufficient affordable housing in Los Angeles, California burdens many renter households with the threat of an eviction. Research has identified individual- and neighborhood-level sociodemographic correlates of eviction, but the uneven distribution of sociodemographic characteristics and housing conditions across neighborhoods likely produces broader patterns of spatial clustering in eviction prevalence across local areas. We use spatial autoregressive models to explain the spatial concentration and spillover effects for two types of formal eviction filings-court-based and no-fault Ellis Act petitions-within and across census tracts in Los Angeles. Court-based filings show greater and more persistent spatial concentration, particularly in neighborhoods with higher percentages of Black residents. We find evidence of spatial correlation for both types of eviction, however, suggesting that identifying the spatial distribution of eviction prevalence across local areas is...

Long-Acting Injectable Therapy for People with HIV: Looking Ahead with Lessons from Psychiatry and Addiction Medicine

Wed, 26 Oct 2022 00:00:00 +0000

Long-acting injectable antiretroviral medications are new to HIV treatment. People with HIV may benefit from a treatment option that better aligns with their preferences, but could also face new challenges and barriers. Authors from the fields of HIV, substance use treatment, and mental health collaborated on this commentary on the issues surrounding equitable implementation and uptake of LAI ART by drawing lessons from all three fields. We employ a socio-ecological framework beginning at the policy level and moving through the community, organizational, interpersonal, and patient levels. We look at extant literature on the topic as well as draw from the direct experience of our clinician-authors.

An adaptive design to screen, treat, and retain people with opioid use disorders who use methamphetamine in methadone clinics (STAR-OM): study protocol of a clinical trial

Thu, 1 Sep 2022 00:00:00 +0000

BackgroundMethamphetamine use could jeopardize the current efforts to address opioid use disorder and HIV infection. Evidence-based behavioral interventions (EBI) are effective in reducing methamphetamine use. However, evidence on optimal combinations of EBI is limited. This protocol presents a type-1 effectiveness-implementation hybrid design to evaluate the effectiveness, cost-effectiveness of adaptive methamphetamine use interventions, and their implementation barriers in Vietnam.MethodDesign: Participants will be first randomized into two frontline interventions for 12 weeks. They will then be placed or randomized to three adaptive strategies for another 12 weeks. An economic evaluation and an ethnographic evaluation will be conducted alongside the interventions.Participants: We will recruit 600 participants in 20 methadone clinics. Eligibility criteria: (1) age 16+; (2) Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) scores ≥ 10 for methamphetamine use...

Disparities In Uptake Of HIV Pre-Exposure Prophylaxis Among California Medicaid Enrollees

Wed, 27 Jul 2022 00:00:00 +0000

One of the pillars of efforts in the US to curb HIV incidence is pre-exposure prophylaxis (PrEP). We examined racial/ethnic and sex disparities in PrEP uptake among California Medicaid enrollees. Claims data from 2019 identified enrollees and PrEP users in each racial/ethnic, sex, and age group, yielding crude uptake rates. We then predicted age-adjusted uptake rates from multivariable logit regressions and divided PrEP uptake estimates by each group's number of new HIV diagnoses to estimate PrEP-to-need ratios. Predicted uptake was highest for White (0.29 percent) and Black (0.23 percent) males and lowest (0.16 percent) for Hispanic males. Rates for males exceeded those for females; however, Black females had twice the rate of PrEP uptake of White females. Black males and females and Hispanic males had PrEP-to-need ratios that were less than one-third (4.0-6.3) those of Asian and White males and females (14.4-19.9). Low PrEP use rates and disparities in uptake...

Women’s well-being during a pandemic and its containment

Mon, 21 Mar 2022 00:00:00 +0000

The COVID-19 pandemic brought the dual crises of disease and the containment policies designed to mitigate it. Yet, there is little evidence on the impacts of these policies on women in lower-income countries, where there may be limited social safety nets to absorb these shocks. We conduct a large phone survey and leverage India's geographically varied containment policies to estimate the association between the pandemic and containment policies and measures of women's well-being, including mental health and food security. On aggregate, the pandemic resulted in dramatic income losses, increases in food insecurity, and declines in female mental health. While potentially crucial to stem the spread of COVID-19, the greater prevalence of containment policies is associated with increased food insecurity, particularly for women, and reduced female mental health. For surveyed women, moving from zero to average containment levels is associated with a 38% increase in the likelihood of...

COVID-19 increased censorship circumvention and access to sensitive topics in China

Mon, 14 Feb 2022 00:00:00 +0000

Crisis motivates people to track news closely, and this increased engagement can expose individuals to politically sensitive information unrelated to the initial crisis. We use the case of the COVID-19 outbreak in China to examine how crisis affects information seeking in countries that normally exert significant control over access to media. The crisis spurred censorship circumvention and access to international news and political content on websites blocked in China. Once individuals circumvented censorship, they not only received more information about the crisis itself but also accessed unrelated information that the regime has long censored. Using comparisons to democratic and other authoritarian countries also affected by early outbreaks, the findings suggest that people blocked from accessing information most of the time might disproportionately and collectively access that long-hidden information during a crisis. Evaluations resulting from this access, negative or positive...

Bridging the Gap Between Pilot and Scale-Up: A Model of Antenatal Testing for Curable Sexually Transmitted Infections From Botswana

Mon, 17 Jan 2022 00:00:00 +0000

BACKGROUND: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are common sexually transmitted infections (STIs) associated with adverse outcomes, yet most countries do not test and conduct syndromic management, which lacks sensitivity and specificity. Innovations allow for expanded STI testing; however, cost is a barrier. METHODS: Using inputs from a pilot program in Botswana, we developed a model among a hypothetical population of 50,000 pregnant women to compare 1-year costs and outcomes associated with 3 antenatal STI testing strategies: (1) point-of-care, (2) centralized laboratory, and (3) a mixed approach (point of care at high-volume sites, and hubs elsewhere), and syndromic management. RESULTS: Syndromic management had the lowest delivery cost but was associated with the most infections at delivery, uninfected women treated, CT/NG-related low-birth-weight infants, disability-adjusted life years, and low birth weight hospitalization costs. Point-of-care CT/NG testing...

COVID-19 and Children’s Well-Being: A Rapid Research Agenda

Mon, 6 Sep 2021 00:00:00 +0000

PurposeUnderstanding the full impact of COVID-19 on U.S. children, families, and communities is critical to (a) document the scope of the problem, (b) identify solutions to mitigate harm, and (c) build more resilient response systems. We sought to develop a research agenda to understand the short- and long-term mechanisms and impacts of the COVID-19 pandemic on children’s healthy development, with the goal of devising and ultimately testing interventions to respond to urgent needs and prepare for future pandemics.DescriptionThe Life Course Intervention Research Network facilitated a series of virtual meetings that included members of 10 Maternal and Child Health (MCH) research programs, their research and implementation partners, as well as family and community representatives, to develop an MCH COVID-19 Research Agenda. Stakeholders from academia, clinical practice, nonprofit organizations, and family advocates participated in four meetings, with 30–35 participants at each meeting.AssessmentInvestigating...

Adoption of community monitoring improves common pool resource management across contexts

Thu, 22 Jul 2021 00:00:00 +0000

Pervasive overuse and degradation of common pool resources (CPRs) is a global concern. To sustainably manage CPRs, effective governance institutions are essential. A large literature has developed to describe the institutional design features employed by communities that successfully manage their CPRs. Yet, these designs remain far from universally adopted. We focus on one prominent institutional design feature, community monitoring, and ask whether nongovernmental organizations or governments can facilitate its adoption and whether adoption of monitoring affects CPR use. To answer these questions, we implemented randomized controlled trials in six countries. The harmonized trials randomly assigned the introduction of community monitoring to 400 communities, with data collection in an additional 347 control communities. Most of the 400 communities adopted regular monitoring practices over the course of a year. In a meta-analysis of the experimental results from the six sites,...

Using a Twitter Chat to Rapidly Identify Barriers and Policy Solutions for Metastatic Breast Cancer Care: Qualitative Study

Mon, 12 Apr 2021 00:00:00 +0000

BACKGROUND: Real-time, rapid assessment of barriers to care experienced by patients can be used to inform relevant health care legislation. In recent years, online communities have become a source of support for patients as well as a vehicle for discussion and collaboration among patients, clinicians, advocates, and researchers. The Breast Cancer Social Media (#BCSM) community has hosted weekly Twitter chats since 2011. Topics vary each week, and chats draw a diverse group of participants. Partnering with the #BCSM community, we used Twitter to gather data on barriers to care for patients with metastatic breast cancer and potential policy solutions. Metastatic breast cancer survival rates are low and in large part conditioned by time-sensitive access to care factors that might be improved through policy changes. OBJECTIVE: This study was part of an assessment of the barriers to care for metastatic breast cancer with the goal of offering policy solutions for the legislative session...

Instructional interventions for improving COVID-19 knowledge, attitudes, behaviors: Evidence from a large-scale RCT in India

Mon, 5 Apr 2021 00:00:00 +0000

Seeking ways to encourage broad compliance with health guidelines during the pandemic, especially among youth, we test two hypotheses pertaining to the optimal design of instructional interventions for improving COVID-19-related knowledge, attitudes, and behaviors. We randomly assigned 8376 lower-middle income youth in urban India to three treatments: a concentrated and targeted fact-based, instructional intervention; a longer instructional intervention that provided the same facts along with underlying scientific concepts; and a control. Relative to existing efforts, we find that both instructional interventions increased COVID-19-related knowledge immediately after intervention. Relative to the shorter fact-based intervention, the longer intervention resulted in sustained improvements in knowledge, attitudes, and self-reported behavior. Instead of reducing attention and comprehension by youth, the longer scientific based treatment appears to have increased understanding and...

The impact of COVID‐19 on small business owners: Evidence from the first three months after widespread social‐distancing restrictions

Mon, 11 Jan 2021 00:00:00 +0000

Social-distancing restrictions and health- and economic-driven demand shifts from COVID-19 are expected to shutter many small businesses and entrepreneurial ventures, but there is very little early evidence on impacts. This paper provides the first analysis of impacts of the pandemic on the number of active small businesses in the United States using nationally representative data from the April 2020 Current Population Survey-the first month fully capturing early effects. The number of active business owners in the United States plummeted by 3.3 million or 22% over the crucial 2-month window from February to April 2020. The drop in active business owners was the largest on record, and losses to business activity were felt across nearly all industries. African-American businesses were hit especially hard experiencing a 41% drop in business activity. Latinx business owner activity fell by 32%, and Asian business owner activity dropped by 26%. Simulations indicate that industry compositions...

The Effect of Hospice on End-of-Life Costs for Terminal Medicare Patients With HIV

Wed, 6 Jan 2021 00:00:00 +0000

One-quarter of annual Medicare expenses in the traditional program (non-Medicare Advantage) are expended for 5% of Medicare enrollees, with much of this expenditure occurring in the last year of life. Hospice use may reduce end-of-life costs. However, evidence has been inconclusive due to sample selection and differences in insurance coverage for hospice. Claims data for HIV-positive Californians enrolled in Medicare who died in the period 2008 to 2010 were used to examine the relationship between hospice use and costs in the last 6 months of life. Logit estimates related hospice use to sickness levels and demographics. Inpatient and outpatient costs were analyzed separately. Logit regressions examined hospitalization probability. Robust regressions were used to examine the determinants of conditional inpatient costs and non-inpatient costs. Bootstrapped post-estimates were then used to determine the marginal probability of costs for the sample by hospice use. Hospice users have...

Do Commodity Price Shocks Cause Armed Conflict? A Meta-Analysis of Natural Experiments

Wed, 28 Oct 2020 00:00:00 +0000

Scholars of the resource curse argue that reliance on primary commodities destabilizes governments: price fluctuations generate windfalls or periods of austerity that provoke or intensify civil conflict. Over 350 quantitative studies test this claim, but prominent results point in differentdirections, making it difficult to discern which results reliably hold across contexts. We conduct a meta-analysis of 46 natural experiments that use difference-in difference designs to estimate the causal effect of commodity price changes on armed civil conflict. We show that commodity pricechanges, on average, do not change the likelihood of conflict. However, there are cross-cutting effects by commodity type. In line with theory, we find price increases for labor-intensive agricultural commodities reduce conflict, while increases in the price of oil, a capital-intensive commodity, provoke conflict. We also find that price increases for lootable artisanal minerals provoke conflict. Our...

A Tale of Two Cities: Exploring the Role of Race/Ethnicity and Geographic Setting on PrEP Use Among Adolescent Cisgender MSM

Wed, 2 Sep 2020 00:00:00 +0000

Although pre-exposure prophylaxis (PrEP) could substantially reduce the risk of HIV acquisition among adolescent cisgender men who have sex with men (cisMSM), various barriers faced by people of color, particularly within the southern region of the U.S., may lead to racial disparities in the utilization of PrEP. Few studies, however, have explored racial/ethnic differences in PrEP use by geographic setting among adolescent cisMSM. We conducted a cross-sectional analysis examining racial disparities in PrEP use among cisMSM ages 15–24 years in New Orleans, Louisiana, and Los Angeles, California recruited between May, 2017 and September, 2019. The odds of PrEP use among AA adolescents were considerably lower than White adolescents in New Orleans (OR (95% CI): 0.24 (0.10, 0.53)), although we did not find evidence of differences in Los Angeles. Our findings underscore the need for targeted interventions to promote PrEP use among adolescent MSM, particularly among AA adolescent...

Do Elections Improve Constituency Responsiveness? Evidence from US Cities

Wed, 8 Jul 2020 00:00:00 +0000

Do elections motivate incumbent politicians to serve their voters? In this paper, we use millions of service requests placed by residents in US cities to measure constituency responsiveness. We then test whether an unusual policy change in New York City, which enabled city councilors to run for three rather than two terms in office, improved constituency responsiveness in previously term-limited councilors' districts. Using difference-in-differences, we find robust evidence for this. Taking advantage of differential timing of local election races in New York City and San Francisco, we also find late-term improvements to responsiveness in districts represented by reelection-seeking incumbents. Elections improve municipal services, but also create cycles in constituency responsiveness. These findings have implications for theories of representative democracy.

Analyzing voter support for California’s local option sales taxes for transportation

Tue, 7 Jul 2020 00:00:00 +0000

Local and regional governments in the U.S. rely increasingly on voter-approved local option sales taxes (LOSTs) to fund transportation capital investments, maintenance, and operations. LOSTs typically present voters with lists of local transportation projects and programs to be funded by a ¼ to 1 percent sales tax increase. Most research on LOSTs are case studies, which make generalizations about LOSTs difficult. We conducted a comprehensive, multi-jurisdictional analysis of LOST measures in California, the U.S. state with the greatest number of LOST measures. We examined 76 LOST measures put to voters between 1976 and 2016 to assess factors associated with voter support. LOSTs in California are enacted by counties, which we examined in addition to smaller intra-county geographies using both regression models and case studies. We tested several explanatory variables for association with voter support including macroeconomic and political context, planned measure expenditures,...

Lessons Learned from 40 Years of Local Option Transportation Sales Taxes in California

Tue, 7 Jul 2020 00:00:00 +0000

Jurisdictions across the United States have increasingly turned to local option sales taxes, or LOSTs, to fund transportation projects and programs. California is an enthusiastic adopter of these measures; since 1976, residents in over half of the state’s 58 counties have voted on 76 LOST measures. As of 2017, 24 counties, home to 88% of the state’s population, have LOST measures in place. Many counties have enacted multiple measures, with passage rates especially high among renewal and follow-on measures. This research is the first comprehensive analysis of LOST measures; drawing on measure expenditure plans to determine the range and frequency of transportation projects and services funded. This detailed review of expenditure plans across dozens of urban, suburban, and rural California counties offers insight on these measures and the projects and programs they fund. Overall, this study finds that LOSTs are heterogeneous, often including something for nearly every interest group....

Initial Health Assessments and HIV Screening under the Affordable Care Act

Sat, 16 May 2020 00:00:00 +0000

BACKGROUND: The Centers for Disease Control and Prevention (CDC) estimates that 156,300 (95% CI 144,100-165,900) Americans living with HIV in 2012 were unaware of their infection. To increase knowledge of HIV status, CDC guidelines seek to make HIV screening a routine part of medical care. This paper examines how routinely California primary care providers test for HIV and how providers' knowledge of California's streamlined testing requirements, use of sexual histories, and having an electronic medical record prompt for HIV testing, relate to test offers. METHODS: We surveyed all ten California health plans offered under health reform's Insurance Exchange (response rate = 50%) and 322 primary care providers to those plans (response rate = 19%) to assess use of HIV screening and risk assessments. RESULTS: Only 31.7% of 60 responding providers reported offering HIV tests to all or most new enrollees and only 8.8% offered an HIV test of blood samples all or most of the time despite...

Sexual and marital trajectories and HIV infection among ever-married women in rural Malawi

Sat, 16 May 2020 00:00:00 +0000

Objective

To explore how sexual and marital trajectories are associated with HIV infection among ever-married women in rural Malawi.

Methods

Retrospective survey data and HIV biomarker data for 926 ever-married women interviewed in the Malawi Diffusion and Ideational Change Project were used. The associations between HIV infection and four key life course transitions considered individually (age at sexual debut, premarital sexual activity, entry into marriage and marital disruption by divorce or death) were examined. These transitions were then sequenced to construct trajectories that represent the variety of patterns in the data. The association between different trajectories and HIV prevalence was examined, controlling for potentially confounding factors such as age and region.

Results

Although each life course transition taken in isolation may be associated with HIV infection, their combined effect appeared to be conditional on the sequence in which they...

Exploring the drivers of health and healthcare access in Zambian prisons: a health systems approach

Sat, 16 May 2020 00:00:00 +0000

BACKGROUND: Prison populations in sub-Saharan Africa (SSA) experience a high burden of disease and poor access to health care. Although it is generally understood that environmental conditions are dire and contribute to disease spread, evidence of how environmental conditions interact with facility-level social and institutional factors is lacking. This study aimed to unpack the nature of interactions and their influence on health and healthcare access in the Zambian prison setting. METHODS: We conducted in-depth interviews of a clustered random sample of 79 male prisoners across four prisons, as well as 32 prison officers, policy makers and health care workers. Largely inductive thematic analysis was guided by the concepts of dynamic interaction and emergent behaviour, drawn from the theory of complex adaptive systems. RESULTS: A majority of inmates, as well as facility-based officers reported anxiety linked to overcrowding, sanitation, infectious disease transmission, nutrition...

Socioeconomic inequalities in HIV/AIDS prevalence in sub-Saharan African countries: evidence from the Demographic Health Surveys

Sat, 16 May 2020 00:00:00 +0000

Introduction

Extant studies universally document a positive gradient between socioeconomic status (SES) and health. A notable exception is the apparent concentration of HIV/AIDS among wealthier individuals. This paper uses data from the Demographic Health Surveys and AIDS Indicator Surveys to examine socioeconomic inequalities in HIV/AIDS prevalence in 24 sub-Saharan African (SSA) countries, the region that accounts for two-thirds of the global HIV/AIDS burden.

Methods

The relative and generalized concentration indices (RC and GC) were used to quantify wealth-based socioeconomic inequalities in HIV/AIDS prevalence for the total adult population (aged 15-49), for men and women, and in urban and rural areas in each country. Further, we decomposed the RC and GC indices to identify the determinants of socioeconomic inequalities in HIV/AIDS prevalence in each country.

Results

Our findings demonstrated that HIV/AIDS was concentrated among higher SES individuals...

Minimum Wage and Overweight and Obesity in Adult Women: A Multilevel Analysis of Low and Middle Income Countries

Sat, 16 May 2020 00:00:00 +0000

OBJECTIVES: To describe the relationship between minimum wage and overweight and obesity across countries at different levels of development. METHODS: A cross-sectional analysis of 27 countries with data on the legislated minimum wage level linked to socio-demographic and anthropometry data of non-pregnant 190,892 adult women (24-49 y) from the Demographic and Health Survey. We used multilevel logistic regression models to condition on country- and individual-level potential confounders, and post-estimation of average marginal effects to calculate the adjusted prevalence difference. RESULTS: We found the association between minimum wage and overweight/obesity was independent of individual-level SES and confounders, and showed a reversed pattern by country development stage. The adjusted overweight/obesity prevalence difference in low-income countries was an average increase of about 0.1 percentage points (PD 0.075 [0.065, 0.084]), and an average decrease of 0.01 percentage points...

A qualitative study of factors affecting mental health amongst low-income working mothers in Bangalore, India

Sat, 16 May 2020 00:00:00 +0000

Background

Low-income urban working mothers face many challenges in their domestic, environmental, and working conditions that may affect their mental health. In India, a high prevalence of mental health disorders has been recorded in young women, but there has been little research to examine the factors that affect their mental health at home and work.

Methods

Through a primarily qualitative approach, we studied the relationship between work, caring for family, spousal support, stress relief strategies and mental health amongst forty eight low-income working mothers residing in urban slums across Bangalore, India. Participants were construction workers, domestic workers, factory workers and fruit and vegetable street vendors. Qualitative data analysis themes included state of mental health, factors that affected mental health positively or negatively, manifestations and consequences of stress and depression, and stress mitigators.

Results

Even in our small...

Adaptation to climate change in the Ontario public health sector

Sat, 16 May 2020 00:00:00 +0000

BackgroundClimate change is among the major challenges for health this century, and adaptation to manage adverse health outcomes will be unavoidable. The risks in Ontario – Canada’s most populous province – include increasing temperatures, more frequent and intense extreme weather events, and alterations to precipitation regimes. Socio-economic-demographic patterns could magnify the implications climate change has for Ontario, including the presence of rapidly growing vulnerable populations, exacerbation of warming trends by heat-islands in large urban areas, and connectedness to global transportation networks. This study examines climate change adaptation in the public health sector in Ontario using information from interviews with government officials.MethodsFifty-three semi-structured interviews were conducted, four with provincial and federal health officials and 49 with actors in public health and health relevant sectors at the municipal level. We identify adaptation efforts,...

Increased Duration of Paid Maternity Leave Lowers Infant Mortality in Low- and Middle-Income Countries: A Quasi-Experimental Study

Sat, 16 May 2020 00:00:00 +0000

BACKGROUND: Maternity leave reduces neonatal and infant mortality rates in high-income countries. However, the impact of maternity leave on infant health has not been rigorously evaluated in low- and middle-income countries (LMICs). In this study, we utilized a difference-in-differences approach to evaluate whether paid maternity leave policies affect infant mortality in LMICs. METHODS AND FINDINGS: We used birth history data collected via the Demographic and Health Surveys to assemble a panel of approximately 300,000 live births in 20 countries from 2000 to 2008; these observational data were merged with longitudinal information on the duration of paid maternity leave provided by each country. We estimated the effect of an increase in maternity leave in the prior year on the probability of infant (<1 y), neonatal (<28 d), and post-neonatal (between 28 d and 1 y after birth) mortality. Fixed effects for country and year were included to control for, respectively, unobserved...

Health and healthcare access among Zambia’s female prisoners: a health systems analysis

Sat, 16 May 2020 00:00:00 +0000

BackgroundResearch exploring the drivers of health outcomes of women who are in prison in low- and middle-income settings is largely absent. This study aimed to identify and examine the interaction between structural, organisational and relational factors influencing Zambian women prisoners’ health and healthcare access.MethodsWe conducted in-depth interviews of 23 female prisoners across four prisons, as well as 21 prison officers and health care workers. The prisoners were selected in a multi-stage sampling design with a purposive selection of prisons followed by a random sampling of cells and of female inmates within cells. Largely inductive thematic analysis was guided by the concepts of dynamic interaction and emergent behaviour, drawn from the theory of complex adaptive systems.ResultsWe identified compounding and generally negative effects on health and access to healthcare from three factors: i) systemic health resource shortfalls, ii) an implicit prioritization of male...

HIV/AIDS, declining family resources and the community safety net

Sat, 16 May 2020 00:00:00 +0000

There are an estimated 15 million AIDS orphans worldwide. Families play an important role in safeguarding orphans, but they may be increasingly compromised by the HIV/AIDS epidemic. The international aid community has recognized the need to help families continue caring for orphaned children by strengthening their safety nets. Before we build new structures, however, we need to know the extent to which community and public safety nets already provide support to families with orphans. To address this gap, we analyzed nationally representative data from 27,495 children in the 2004-2005 Malawi Integrated Household Survey. We found that communities commonly assisted orphan households through private transfers; organized responses to the orphan crisis were far less frequent. Friends and relatives provided assistance to over 75% of orphan households through private gifts, but the value of such support was relatively low. Over 40% of orphans lived in a community with support groups for...

Missed Opportunities for HIV Screening of New Enrollees in California’s Low Income Health Program

Tue, 3 Mar 2020 00:00:00 +0000

The objective of this study was to measure HIV screening rates and variables associated with screening among new enrollees in California's Low Income Health Program (LIHP). A logit model was used to estimate associations between HIV screening and enrollment, claims, and encounter data for enrollees. HIV prevalence among new LIHP enrollees was 1.2%xd. Among 42,550 new LIHP enrollees with no prior HIV diagnosis, only 27% received screening within 12 months of their first medical evaluation. A total of 350 new HIV diagnoses were identified (incidence rate of 0.8%), exceeding the 0.1% level at which the Centers for Disease Control and Prevention (CDC) recommends routine HIV screening. California reduced screening barriers by removing required written informed consent and pretest counseling; the Affordable Care Act (ACA) eliminated cost-sharing and enhanced access. Removing financial and administrative barriers to HIV screening is necessary, but may be insufficient to reach CDC's recommended...

Daytime Locations in Spatial Mismatch: Job Accessibility and Employment at Reentry From Prison.

Tue, 18 Feb 2020 00:00:00 +0000

Individuals recently released from prison confront many barriers to employment. One potential obstacle is spatial mismatch-the concentration of low-skilled, nonwhite job-seekers within central cities and the prevalence of relevant job opportunities in outlying areas. Prior research has found mixed results about the importance of residential place for reentry outcomes. In this article, we propose that residential location matters for finding work, but this largely static measure does not capture the range of geographic contexts that individuals inhabit throughout the day. We combine novel, real-time GPS information on daytime locations and self-reported employment collected from smartphones with sophisticated measures of job accessibility to test the relative importance of spatial mismatch based on residence and daytime locations. Our findings suggest that the ability of low-skilled, poor, and urban individuals to compensate for their residential deficits by traveling to job-rich...

Measuring the geography of opportunity

Tue, 18 Feb 2020 00:00:00 +0000

Quantitative segregation research focuses almost exclusively on the spatial sorting of demographic groups. This research largely ignores the structural characteristics of neighborhoods – such as crime, job accessibility, and school quality – that likely help determine important household outcomes. This paper summarizes the research on segregation, neighborhood effects, and concentrated disadvantage, and argues that we should pay more attention to neighborhood structural characteristics, and that the data increasingly exist to include measures of spatial segregation and neighborhood opportunity. The paper concludes with a brief empirical justification for the inclusion of data on neighborhood violence and a discussion on policy applications.
