Privacy guarantees for personal mobility data in humanitarian response.

Personal mobility data from mobile phones and other sensors are increasingly used to inform policymaking during pandemics, natural disasters, and other humanitarian crises. However, even aggregated mobility traces can reveal private information about individual movements to potentially malicious actors. This paper develops and tests an approach for releasing private mobility data, which provides formal guarantees over the privacy of the underlying subjects.

Social determinants for understanding Muslims' intentions toward seeking mental health help based on the Theory of Planned Behavior.

Background: Many have found that minorities seek help for mental health problems less than the general population. Such findings are surprising considering that minorities experience higher rates of mental health issues compared to the general population.

Objectives: Employing the Theory of Planned Behavior (TPB), this study aimed to explore the intentions of Muslims living in California and Israel pertaining seeking mental health help (SMHH).

Development of the Longitudinal Study of Health and Ageing in Kenya (LOSHAK).

In Kenya, the number of adults aged ≥60 is expected to nearly quadruple by 2050, making it one of the most rapidly aging countries in Sub-Saharan Africa (SSA). Accordingly, we designed the Longitudinal Study of Health and Ageing in Kenya (LOSHAK) to generate novel data to address the health and economic consequences of this demographic transition. Specifically, LOSHAK will investigate the social, economic, environmental, biological, and policy processes that shape late-life health and economic well-being in Kenya.

Can a private sector engagement intervention that prioritizes pro-poor strategies improve healthcare access and quality? A randomized field experiment in Kenya.

Private sector engagement in health reform has been suggested to help reduce healthcare inequities in sub-Saharan Africa, where populations with the most need seek the least care. We study the effects of African Health Markets for Equity (AHME), a cluster randomized controlled trial carried out in Kenya from 2012 to 2020 at 199 private health clinics. AHME included four clinic-level interventions: social health insurance, social franchising, SafeCare quality-of-care certification programme and business support.

COVID-19 and mental health in 8 low- and middle-income countries: A prospective cohort study.

Background: The Coronavirus Disease 2019 (COVID-19) pandemic and associated mitigation policies created a global economic and health crisis of unprecedented depth and scale, raising the estimated prevalence of depression by more than a quarter in high-income countries. Low- and middle-income countries (LMICs) suffered the negative effects on living standards the most severely. However, the consequences of the pandemic for mental health in LMICs have received less attention.

Estimating an Equilibrium Model of Horizontal Competition in Education.

The quality of the match between students and schools affects learning, but little is known about the magnitude of these effects or how they respond to changes in market structure. I develop a quantitative equilibrium model of school competition with horizontal competition in match quality. I estimate the model using data from Pakistan, a country with high private enrollment, and (1) quantify the importance of good matches, (2) show that profit-maximizing private schools' choices of quality advantage wealthier students, increasing inequality and reducing welfare and learning, and (3) provide intuition for when interventions in the market are valuable.

Use of community engagement interventions to improve child immunisation in low- and middle-income countries: A systematic review and meta-analysis.

Immunisation is one of the most cost-effective interventions to prevent and control life-threatening infectious diseases. Nonetheless, rates of routine vaccination of children in low- and middle-income countries (LMICs) are strikingly low or stagnant. In 2019, an estimated 19.

Protocol for validation of the Global Scales for Early Development (GSED) for children under 3 years of age in seven countries.

Introduction: Children's early development is affected by caregiving experiences, with lifelong health and well-being implications. Governments and civil societies need population-based measures to monitor children's early development and ensure that children receive the care needed to thrive. To this end, the WHO developed the Global Scales for Early Development (GSED) to measure children's early development up to 3 years of age.

Elaboration of parents' schemas of their children: Unique relations to sensitivity and learning support among families living in poverty.

This study examined how distinct aspects of parents' schemas of their children are related to caregiving behaviors. It included 242 families with toddlers and young children, most of whom were living in poverty (37% White, 25% Black, 19% Latine, 17% Multiracial, and 2% Asian; child age = 21-39 months; median family income = $1,555 per month). The elaboration and emotional valence of parents' schemas were coded from brief responses to open-ended questions about children's personality; observations of parents' sensitivity and learning support were assessed in structured and unstructured settings.

The Syrian regime's apparatus for systemic torture: A qualitative narrative study of testimonies from survivors.

Background: Despite broad interest of the Syrian refugee plight in the academic and media circles, there are still limited studies analyzing the lived experiences of torture survivors under the Syrian regime. This qualitative study interviewed torture survivors to examine the form and function of the Syrian regime's security apparatus, and the personal aftermath of survivors.

Methods: Thirteen in-depth interviews were conducted in Arabic with Syrian refugees who endured torture.

Use of community engagement interventions to improve child immunisation in low-income and middle-income countries: a systematic review and meta-analysis.

Objective: To support evidence informed decision-making, we systematically examine the effectiveness and cost-effectiveness of community engagement interventions on routine childhood immunisation outcomes in low-income and middle-income countries (LMICs) and identify contextual, design and implementation features associated with effectiveness.

Design: Mixed-methods systematic review and meta-analysis.

Data Sources: 21 databases of academic and grey literature and 12 additional websites were searched in May 2019 and May 2020.

Early child stimulation, linear growth and neurodevelopment in low birth weight infants.

Background: Children with low birth weight (LBW) are at risk of linear growth faltering and developmental deficits. Evidence suggests that early child stimulation and care reflected as responsive caregiving and opportunities for learning can promote development. The current analysis aimed to measure the extent to which linear growth and early child stimulation modify each other's association with neurodevelopmental outcomes among LBW infants.

COVID-19 market disruptions and food security: Evidence from households in rural Liberia and Malawi.

We use data collected from panel phone surveys to document the changes in food security of households in rural Liberia and Malawi during the market disruptions associated with the COVID-19 lockdowns in 2020. We use two distinct empirical approaches in our analysis: (a) an event study around the date of the lockdowns (March to July 2020), and (b) a difference-in-differences analysis comparing the lockdown period in 2020 to the same months in 2021, in order to attempt to control for seasonality. In both countries, market activity was severely disrupted and we observe declines in expenditures.

Staying alive includes adaptations for catalyzing cooperation.

The target article interprets women's lower competitiveness than men's as evidence of adaptation to help women avoid physical conflicts and stay alive. This commentary advances the additional hypothesis that strategically suppressing competitiveness, thus signaling egalitarian intentions, could be an adaptation to catalyze cooperative behavior from males and females, turning natural competitors (other women) into allies and men into supportive partners.

The Impact of Cleft Lip/Palate and Surgical Intervention on Adolescent Life Outcomes.

Background: Cleft lip/palate (CLP) is a congenital orofacial anomaly appearing in approximately one in 700 births worldwide. While in high-income countries CLP is normally addressed surgically during infancy, in developing countries CLP is often left unoperated, potentially impacting multiple dimensions of life quality. Previous research has frequently compared CLP outcomes to those of the general population.

Streamlined versus traditional consent for low-risk comparative effectiveness trials: a randomized experimental study to measure patients' and public attitudes.

Streamlining consent for low-risk comparative effectiveness research (CER) could facilitate research, while safeguarding patients' rights. 2618 adults were randomized to one of seven consent approaches (six streamlined and one traditional) for a hypothetical, low-risk CER study. A survey measured understanding, voluntariness, and feelings of respect.

What kind of parenting is associated with early self-control among toddlers living in poverty? The importance of learning support.

The present study examined what kind of parenting best supports toddlers' self-control in the context of poverty. Parents and toddlers (52% female; = 2.60 years) in 117 families (35% White, 25% Black, 22% Latinx, 15% Multiracial, and 3% Asian; family income = $1,845/month) engaged in structured interaction tasks, and toddlers completed a snack delay task concurrently and after 6 months.

Reporting all results efficiently: A RARE proposal to open up the file drawer.

While the social sciences have made impressive progress in adopting transparent research practices that facilitate verification, replication, and reuse of materials, the problem of publication bias persists. Bias on the part of peer reviewers and journal editors, as well as the use of outdated research practices by authors, continues to skew literature toward statistically significant effects, many of which may be false positives. To mitigate this bias, we propose a framework to enable authors to report all results efficiently (RARE), with an initial focus on experimental and other prospective empirical social science research that utilizes public study registries.

Effect of universal HIV testing and treatment on socioeconomic wellbeing in rural Kenya and Uganda: a cluster-randomised controlled trial.

Background: Universal testing and treatment for HIV has shown promise as an approach to reduce mortality and lower HIV incidence. Evidence on the economic effects of this approach on individuals and households in low-resource settings is scarce. We aimed to examine the effect of universal HIV testing and treatment on a range of economic outcomes.

Infrastructure alone cannot ensure resilience to weather events in drinking water supplies.

Climate resilient water supplies are those that provide access to drinking water that is sustained through seasons and through extreme events, and where good water quality is also sustained. While surface and groundwater quality are widely understood to vary with rainfall, there is a gap in the evidence on the impact of weather and extremes in rainfall and temperature on drinking water quality, and the role of changes in water system management. A three-country (Bangladesh, Nepal and Tanzania) observational field study tracked 2353 households clustered around 685 water sources across seven different geographies over 14 months.

Self-reported vs Directly Observed Face Mask Use in Kenya.

This cross-sectional study examines the extent to which mask mandates are followed and quantify the bias of self-reported mask usage in Kenya.

Validation of the Infant and Young Child Development (IYCD) Indicators in Three Countries: Brazil, Malawi and Pakistan.

Background: The early childhood years provide an important window of opportunity to build strong foundations for future development. One impediment to global progress is a lack of population-based measurement tools to provide reliable estimates of developmental status. We aimed to field test and validate a newly created tool for this purpose.

Twenty-year economic impacts of deworming.

Estimating the impact of child health investments on adult living standards entails multiple methodological challenges, including the lack of experimental variation in health status, an inability to track individuals over time, and accurately measuring living standards and productivity in low-income settings. This study exploits a randomized school health intervention that provided deworming treatment to Kenyan children, and uses longitudinal data to estimate impacts on economic outcomes up to 20 y later. The effective respondent tracking rate was 84%.

Warming from tropical deforestation reduces worker productivity in rural communities.

The accelerating loss of tropical forests in the 21st century has eliminated cooling services provided by trees in low latitude countries. Cooling services can protect rural communities and outdoor workers with little adaptive capacity from adverse heat exposure, which is expected to increase with climate change. Yet little is still known about whether cooling services can mitigate negative impacts of heat on labor productivity among rural outdoor workers.
