Neighbourhood-level variations in psychosis prevalence and involuntary psychiatric admissions

Studies have highlighted geographical variations in psychosis and involuntary psychiatric admissions. However, the association of neighbourhood-level factors on these variations remains underexplored. Aims To investigate geographical variations in psychosis prevalence and involun...

Optimal Participant Allocation in Individually‐Randomized Stepped‐Wedge Clinical Trials With One or More Treatments: Extensions to Realistic Settings

ABSTRACT In stepped‐wedge clinical trials the patients are randomized into separate groups. Each group transitions from no treatment to treatment at a different time period. The designs are useful when limited resources or geographical constraints make it impossible to treat all...

Mutual Suspicion: Race, Corruption and Humanitarianism in Eastern DR Congo

Suspicion of corruption in crisis is central to debates about who counts as an authentic humanitarian. This article examines suspicions of corruption in global humanitarianism in the eastern Democratic Republic of the Congo: between humanitarian colleagues, as well as humanitaria...

Economic evaluation of adaptation interventions to reduce the adverse health effects of temperature extremes: a systematic review

Abstract Background Extreme heat and cold cause substantial morbidity, productivity, mortality, and wellbeing losses, yet economic evidence on adaptation remains fragmented. This systematic review synthesised full economic evaluations of adaptation interventions addressing the ad...

Low catastrophic expenditure, high unmet need in Lesotho: Rethinking financial protection indicators for universal health coverage

Abstract Introduction Achieving universal health coverage (UHC) requires both, service access and financial risk protection. This study provides the first comprehensive UHC assessment for Lesotho, highlighting a critical measurement challenge relevant to many LMICs. Methods We co...

Sparse Bayesian Joint Modal Estimation for Exploratory Item Factor Analysis

This study presents a scalable Bayesian estimation algorithm for sparse estimation in exploratory item factor analysis based on a classical Bayesian estimation method, namely Bayesian joint modal estimation (BJME). BJME jointly estimates the model parameters and factor scores by...

Determining a graph from its reconfiguration graph

Given a graph G and a natural number k , the k -recolouring graph C k ( G ) is the graph whose vertices are the k -colourings of G and whose edges link pairs of colourings which differ at exactly one vertex of G . Recently, Hogan et al. proved that G can be determined from C k (...

“Everybody loves to hate methodological nationalism”: methodological reflections on moving beyond the nation-state in research design and practice

Surpassing the constraints of methodological nationalism has become one of the main questions in migration studies. Yet the nation-state framework continues to dominate research on migration. In this paper, we draw on two multi-sited fieldworks to discuss how to address methodolo...

Proximity as populist performance: A video data analysis of the 2023 Turkish elections

This dataset includes: 1) 92 videos analyzed in the article “Proximity as Populist Performance: A Video Data Analysis of the 2023 Turkish Elections.” 2) An Excel file containing the coding results for all situations identified in the videos. 3) A table listing the names and polit...

Adapting and implementing health systems guidelines: learning lessons from countries

Adapting and implementing evidence-based health system guidelines presents numerous challenges, particularly when they are introduced in settings that differ from those in which they were originally developed [ 1 ]. Effective implementation requires careful consideration of local...

Popular pressure, mock compliance or leadership as distraction: the UK’s approach to beneficial ownership transparency

Since the 2008 financial crisis, the United Kingdom (UK) has positioned itself as a global leader in beneficial ownership transparency, pioneering public registers of UK companies and of overseas companies that own real estate. This paper asks what is behind the UK’s leadership a...

Spatio-temporal autoregressions for high dimensional matrix-valued time series

Motivated by predicting intraday trading volume curves, we consider two spatio-temporal autoregressive models for matrix time series, in which each column may represent daily trading volume curve of one asset, and each row captures synchronized 5-minute volume intervals acrossmul...

Barriers and enablers for health system reform

Introduction Health systems worldwide face escalating pressure from the growing burden of non-communicable diseases and population ageing, as well as chronic workforce shortages, infrastructure limitations, and structural misalignment between care models designed for acute illnes...

Pre-exposure prophylaxis as a complementary vaccination strategy to reduce rabies in Kerala, India: a cost-effectiveness modelling study

Background Post-exposure prophylaxis (PEP) and dog vaccination continue to be the widely adopted vaccination strategy for rabies control in high-burden countries like India. To determine the public health and economic impacts of childhood pre-exposure prophylaxis (PrEP) relative...

Discretionary disclosure and electoral accountability

Politicians often have discretion over what policy information to reveal to the public. This paper develops a formal model comparing electoral accountability under mandatory and discretionary disclosure. I identify a fundamental trade-off between detection − where voters directly...

A New Origin for Entropy: Jauch’s Conservation Law and the Geometry of Thermodynamics

Abstract A central question for the foundations of thermodynamics is which conceptual structures underpin the existence of entropy and temperature. Jauch claimed that entropy and temperature could be derived from a novel conservation law. This paper reconstructs the physics and m...

Motivating executives for the long run: executive compensation stickiness, long-term focus and the radicalness of corporate innovation

Purpose Radical innovation is crucial for the long-term survival of firms, yet it remains challenging to achieve for most firms. To validate the theoretical rationale of executive compensation stickiness and link managerial cognition to corporate innovation, this study draws on t...

Private Equity Ownership and Firm Performance: A Framework for Interpreting the Evidence

We review the evidence on the impact of private equity (PE) ownership on firms, stakeholders, and the economy. We organize this literature using a framework that emphasizes the costs and benefits of PE as an ownership form and implies five main predictions: (i) only some firms ar...

The effect of proximity of COVID-19 test facilities on test uptake: two quasi-experimental trials

Access to testing sites is a critical component in reducing the spread of a virus during infectious disease outbreaks. For example, distance to the testing site has been mentioned as an important self-reported barrier for test uptake during the COVID-19 pandemic. Despite its impo...

PyCFRL: A Python library for counterfactually fair offline reinforcement learning via sequential data preprocessing

Reinforcement learning (RL) aims to learn and evaluate a sequential decision rule, often referred to as a "policy", that maximizes the population-level benefit in an environment across possibly infinitely many time steps. However, the sequential decisions made by an RL algorithm,...
