Improving child mental health and learning outcomes and reducing stigma and discrimination in conflict setting: findings from a cluster randomized controlled trial of a classroom‐based psychosocial intervention in rural primary schools in Afghanistan

Journal of Child Psychology and Psychiatry, EarlyView.
Background Conflict and crises have long‐lasting and dramatic consequences on the mental health of children. We aimed to investigate the effectiveness of a psychosocial intervention on child mental health in Afghanistan. Methods A two‐arm cluster‐randomized controlled trial was conducted in 83 rural primary schools within three provinces of Afghanistan.

Product Positioning and Incentives to Innovate

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper shows that product positioning affects the incentives to invest in process innovation. The result is found using a model of price competition with three firms under horizontal product differentiation—and then extended to a more general Bertrand triopoly.

Difference‐Makers for Robust Implementation of a Nursing Home Advance Care Planning Embedded Pragmatic Clinical Trial

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Introduction Embedded pragmatic clinical trials are an ideal way to develop and evaluate evidence‐based interventions in the nursing home (NH) environment to facilitate streamlining implementation after study completion. However, there is minimal information available about the necessary and sufficient conditions of “difference makers” for ...

Tensor Changepoint Detection and Eigenbootstrap

Journal of Time Series Analysis, EarlyView.
ABSTRACT Tensor data consisting of multivariate outcomes over the items and across the subjects with longitudinal and cross‐sectional dependence are considered. A completely distribution‐free and tweaking‐parameter‐free detection procedure for changepoints at different locations is designed, which does not require training data.

Online Jump and Kink Detection in Segmented Linear Regression: Statistical Optimality Meets Computational Efficiency

Journal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of sequential (online) estimation of a single change point in a piecewise linear regression model under a Gaussian setup. We demonstrate that certain CUSUM‐type statistics attain the minimax optimal rates for localizing the change point.

Measure‐valued processes for energy markets

Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

On the Impact of Government Debt on Income Distribution in a Post‐Keynesian Framework With Workers' Saving

Metroeconomica, EarlyView.
ABSTRACT This paper examines the complex relationship between government debt and income distribution within a post‐Keynesian framework. Extending the model of You and Dutt (1996), we model both capitalists and workers as holders of government bonds, enabling a more nuanced analysis of income distribution dynamics.

Can we repudiate ontology altogether?

Noûs, EarlyView.
Abstract Ontological nihilists repudiate ontology altogether, maintaining that ontological structure is an unnecessary addition to our theorizing. Recent defenses of the view involve a sophisticated combination of highly expressive but ontologically innocent languages combined with a metaphysics of features—non‐objectual, complete but modifiable states

Aggregation and the Structure of Value

Noûs, EarlyView.
ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

Is A Little Learning Dangerous?

Noûs, EarlyView.
ABSTRACT I argue that a little learning is often dangerous even for ideal reasoners who are operating in extremely simple scenarios and know all the relevant facts about how the evidence is generated. More precisely, I show that, on many plausible ways of assigning value to a credence in a hypothesis H, ideal Bayesians should sometimes expect other ...
