Harvesting benefits: Exploring the effects of second‐best policies on enhancing soil organic carbon stocks in agriculture

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Agricultural subsidies can be an effective policy tool to enhance soil organic carbon sequestration. This paper assesses the effectiveness of a second‐best hypothetical policy which subsidizes additional canola hectares optimally for each soil zone in Saskatchewan in an effort to increase soil organic carbon.

Motivational ecologies in AI‐supported classrooms: Teachers and ChatGPT as dual agents

open access: yesBritish Journal of Educational Psychology, EarlyView.
Abstract Background Generative artificial intelligence (GenAI) tools such as ChatGPT are increasingly integrated into classroom practice, yet their motivational–emotional implications remain insufficiently understood. Situated expectancy–value theory (SEVT) conceptualizes motivation and emotion as embedded in contextual affordances, raising the ...

When machines join the moral circle: The persona effect of generative AI agents in collaborative reasoning

open access: yesBritish Journal of Educational Technology, EarlyView.
Abstract Generative AI is increasingly positioned as a peer in collaborative learning, yet its effects on ethical deliberation remain unclear. We report a between‐subjects experiment with university students (N = 217) who discussed an autonomous‐vehicle dilemma in triads under three conditions: human‐only control, supportive AI teammate or contrarian ...

From tetrachoric to kappa: How to assess reliability on binary scales

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Reliability is crucial in psychometrics, reflecting the extent to which a measurement instrument can discriminate between individuals or items. While classical test theory and intraclass correlation coefficients are well‐established for quantitative scales, estimating reliability for binary outcomes presents unique challenges due to their ...

Bayesian inference for dynamic Q matrices and attribute trajectories in hidden Markov diagnostic classification models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...

Positive and Negative Experiences of Caring Among Adolescent Young Carers

open access: yesChildren &Society, EarlyView.
ABSTRACT Research has highlighted that adolescent young carers (AYCs) are in a vulnerable position due to their caring responsibilities being combined with the challenges of adolescence. However, caring among adolescents does not have to be a solely negative experience and positive experiences of caring can co‐exist.

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

open access: yesConservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Placebo zones in discontinuity‐based designs: Estimation, inference, and implementation

open access: yesEconomic Inquiry, EarlyView.
Abstract We propose a new model‐selection algorithm for regression discontinuity design and related estimators. The performance of candidate models is assessed within a “placebo zone” of the running variable. Candidate models can differ by bandwidth and other choice parameters.

The U‐shaped effect of logic multiplicity on organizational performance: Evidence from the US healthcare industry

open access: yesEuropean Management Review, EarlyView.
Abstract We investigate the effect of logic multiplicity on organizational performance and hypothesize that logics may impact performance in view of their sheer number. We further propose that the market logic embedded in the for‐profit legal form can positively moderate the impact of multiple logics on performance.
