A sound methodology: Measuring experiences of violent conflict through audio self-interviews.

This paper investigates the impact of different survey administration methods on the disclosure of sensitive or traumatic experiences. Respondents of a pilot study in Ethiopia were randomly assigned to answer questions either using audio computer-assisted self-interviewing (ACASI) or as part of a face-to-face (FtF) enumerator-based interview. Results indicate that ACASI led to higher disclosure rates of conflict-related experiences, particularly for the most sensitive questions, i.

Social innovation in access to healthcare: community-based health insurance among Senegalese migrants in Spain.

Background: In several European Union countries, undocumented migrants face significant barriers to accessing universal healthcare. In Spain, Royal Decree-Law 16/2012 introduced restrictions that limited undocumented migrants' access to healthcare services, offering only emergency, maternal, and paediatric care. The implementation of this law created significant disparities in access to healthcare across regions.

A common factor underlying individual differences in confirmation bias.

When they are asked to test a given hypothesis, individuals tend to be biased towards confirming evidence. This phenomenon has been documented on different cognitive components: information search, weighing of evidence, and memory recall. However, the interpretation of these observations has been debated, and it remains unclear whether they truly reflect a confirmation bias (as opposed to e.

Frailty Indicator over the Adult Life Cycle as a Predictor of Healthcare Expenditure and Mortality in the Short to Midterm.

Background: Assessing frailty from middle age onward offers valuable insights into predicting healthcare expenditures throughout the life cycle.

Objectives: This paper examines the use of physical frailty as an indicator of healthcare demand across all age groups. The originality of this work lies in extending the analysis of frailty indicators beyond the typical focus on individuals under 50 years old to include those in mid-life and older.

Effectiveness of ex ante honesty oaths in reducing dishonesty depends on content.

Dishonest behaviours such as tax evasion impose significant societal costs. Ex ante honesty oaths-commitments to honesty before action-have been proposed as interventions to counteract dishonest behaviour, but the heterogeneity in findings across operationalizations calls their effectiveness into question. We tested 21 honesty oaths (including a baseline oath)-proposed, evaluated and selected by 44 expert researchers-and a no-oath condition in a megastudy involving 21,506 UK and US participants from Prolific.

Does personality matter? Exploring its moderating role on the relationship between neighbourhood ethnic outgroup-size and preferences for Brexit.

Prior research has examined the relationship between ethnic outgroup-size at the neighbourhood level and Brexit support, yet there is a lack of understanding on the factors that moderate these effects. This paper critically extends prior debate by focusing on how personality traits moderate not only the extent to which the levels (2011) of ethnic outgroup-size in individuals' residential neighbourhoods but also the increase thereof (2001-2011) are associated with individuals' preferences about the 2016 Brexit referendum. Using data from Understanding Society, we find that two personality traits, agreeableness and openness, are key moderators affecting the above-mentioned relationship.

Stroke but no hospital admission: Lost opportunity for whom?

To counter the spread of COVID-19, the French government imposed several stringent social and political measures across its entire population. We hereto assess the impact of these political decisions on healthcare access in 2020, focusing on patients who suffered from an ischemic stroke. We divide our analysis into four distinct periods: the pre-COVID-19 pandemic period, the lockdown period, the "in-between" or transitional period, and the shutdown period.

Loneliness during the COVID-19 pandemic: Evidence from five European countries.

We use quarterly panel data from the COME-HERE survey covering five European countries to analyse three facets of the experience of loneliness during the COVID-19 pandemic. First, in terms of prevalence, loneliness peaked in April 2020, followed by a U-shape pattern in the rest of 2020, and then remained relatively stable throughout 2021 and 2022. We then establish the individual determinants of loneliness and compare them to those found in the literature predating the COVID-19 pandemic.

A Systematic Review of the Impact of Spinal Cord Injury on Costs and Health-Related Quality of Life.

Objective: To systematically review the health-related quality of life (HRQoL) burden and costs of spinal cord injury (SCI) on health services, patients and wider society.

Methods: A systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement was conducted in March 2021 through Scopus, PubMed and Embase databases. Inclusion criteria were quantitative studies on SCI reporting healthcare costs, social costs and/or HRQoL measured with the Euroqol EQ-5D or Short-Form 36.

Air pollution, viral spread and health outcomes evidence from strikes in France.

To evidence the impact of air pollution on the health of urban populations, several studies use natural experiments that shift commuting from public transport to cars (or vice-versa). However, as public transport use declines, reduced interpersonal contact may lead to slower virus spread and thus lower respiratory morbidity. Using a difference-in-differences strategy, we show that respiratory hospitalisations are both positively affected by air pollution and negatively affected by viral spread following partial unavailability of public transport due to strikes in the ten most populated French cities during the period 2010-2015.

Large and unequal life expectancy declines during the COVID-19 pandemic in India in 2020.

Global population health during the COVID-19 pandemic is poorly understood because of weak mortality monitoring in low- and middle-income countries. High-quality survey data on 765,180 individuals, representative of one-fourth of India's population, uncover patterns missed by incomplete vital statistics and disease surveillance. Compared to 2019, life expectancy at birth was 2.

Do Behavioral Characteristics Influence the Breast Cancer Diagnosis Delay? Evidence From French Retrospective Data.

Objectives: This study aimed to analyze the behavioral determinants of breast cancer (BC) diagnosis delays in France. To do so, we investigated whether time discounting, risk tolerance, and personality traits influenced the BC diagnosis delay of patients.

Methods: We used original retrospective data collected on 2 large online patient networks from 402 women diagnosed of BC.

Mental health and the overall tendency to follow official recommendations against COVID-19: A U-shaped relationship?

This paper investigates the association between several mental health indicators (depression, anxiety, stress, and loneliness) and the overall tendency to follow official recommendations regarding self-protection against COVID-19 (i.e., overall compliance).

Promoting Psychological Well-being in Preschoolers Through Mindfulness-based Socio-emotional Learning: A Randomized-controlled Trial.

Mental health issues in children and young people are frequent and can have enduring negative consequences. Preventive early interventions delivered at school may foster psychological well-being, and preliminary evidence suggests that mindfulness-based social and emotional learning (SEL) interventions have positive effects on children's mental health. The aim of this study was to evaluate a mindfulness-based SEL curriculum including a French adaptation of the Kindness Curriculum (KC), delivered by pre-kindergarten teachers, in a cluster randomized control trial.

Staff Resources in Public and Private Hospitals and Their Implication for Medical Practice: A French Study of Caesareans.

This study aimed to investigate the effect of hospital staffing resources on medical practice in public versus private hospitals. We used exhaustive delivery data from a French district of 11 hospitals over an 11-year period, from 2008 to 2018, including 168,120 observations. We performed multilevel logistic regression models with hospital fixed or random effects, while controlling for factors known to influence obstetric practice.

The association between consideration of future consequences and food intake is mediated by food choice motives in a French adult population.

Objectives: Consideration of future consequences (CFC) distinguishes individuals who adopt behaviours based on immediate needs and concerns from individuals who consider the future consequences of their behaviours. We aimed to assess the association between CFC and diet, and testing the mediating role of food choice motives on this relationship.

Design: Individuals (aged ≥ 18 years) completed the CFC-12 questionnaire in 2014, at least three 24-h dietary records, and a food choice motive questionnaire.

Observational studies generate misleading results about the health effects of air pollution: Evidence from chronic air pollution and COVID-19 outcomes.

Several observational studies from locations around the globe have documented a positive correlation between air pollution and the severity of COVID-19 disease. Observational studies cannot identify the causal link between air quality and the severity of COVID-19 outcomes, and these studies face three key identification challenges: 1) air pollution is not randomly distributed across geographies; 2) air-quality monitoring networks are sparse spatially; and 3) defensive behaviors to mediate exposure to air pollution and COVID-19 are not equally available to all, leading to large measurement error bias when using rate-based COVID-19 outcome measures (e.g.

Distributionally sensitive measurement and valuation of population health.

We introduce a measure of population health that is sensitive to inequality in both age-specific health and lifespan and can be calculated from a health-extended period life table. By allowing for inequality aversion, the measure generalises health-adjusted life expectancy without requiring more data. A transformation of change in the (life-years) measure gives a distributionally sensitive monetary valuation of change in population health and disease burden.

Foundations of utilitarianism under risk and variable population.

Utilitarianism is the most prominent social welfare function in economics. We present three new axiomatic characterizations of utilitarian (that is, additively-separable) social welfare functions in a setting where there is risk over both population size and individuals' welfares. We first show that, given uncontroversial basic axioms, Blackorby et al.

Identifying technology clusters based on automated patent landscaping.

We introduce a new general methodological approach for accurately and consistently retrieving a large set of patents related to specific technologies. We build upon the automated patent landscaping algorithm by incorporating a tractable amount of human supervision to improve the accuracy and consistency of our results. We demonstrate the efficacy of our approach by applying it to six novel and representative technologies: additive manufacturing, blockchain, computer vision, genome editing, hydrogen storage, and self-driving vehicles.

The international diffusion of food innovations and the nutrition transition: retrospective longitudinal evidence from country-level data, 1970-2010.

Introduction: There is a lack of quantitative evidence on the role of food innovations-new food ingredients and processing techniques-in the nutrition transition.

Objective: Document the distribution of food innovations across 67 high-income (HIC) and middle-income (MIC) countries between 1970 and 2010, and its association with the nutritional composition of food supply.

Methods: We used all available data on food patents, as compiled by the European Patent Office, to measure food innovations.

Specificity and sensitivity of the fixed-point test for binary mixture distributions.

When two cognitive processes contribute to a behavioral output-each process producing a specific distribution of the behavioral variable of interest-and when the mixture proportion of these two processes varies as a function of an experimental condition, a common density point should be present in the observed distributions of the data across said conditions. In principle, one can statistically test for the presence (or absence) of a fixed point in experimental data to provide evidence in favor of (or against) the presence of a mixture of processes, whose proportions are affected by an experimental manipulation. In this paper, we provide an empirical diagnostic of this test to detect a mixture of processes.

The structure of global cultural networks: Evidence from the diffusion of music videos.

We apply the independent cascade network inference model to a large database of music videos to infer the structure of the global network of music diffusion. The derived network reveals an intricate topology-fully interconnected, exhibiting a modular structure, and characterized by asymmetric links. We explore the relationship between the identified bilateral cultural diffusion pathways and the geographical and cultural distances among countries, and key socioeconomic interactions such as international trade and migration.

The Gender-Equality Paradox in Chess Holds Among Young Players: A Commentary on the Vishkin (2022) Study.

Vishkin (2022) shows that female participation in chess is lower in more gender equal countries (the "gender-equality paradox") but that this relation is driven by the mean age of the players in a country, which makes it more of an epiphenomenon than a real paradox. Relying on the same data on competitive chess players ( = 768,480 from 91 countries) as well as on data on 15-year-old students ( = 312,571 from 64 countries), we show that the gender-equality paradox for chess holds among young players. The paradox also remains on the whole population of chess players when controlling for the age of the players at the individual rather than at the country level or when controlling for age differences across countries.
