Key management practices controlling yield performance and nitrate leaching in a grass-clover based organic crop rotation

Organic farming is frequently discussed as a strategy for mitigating nitrate leaching, especially in water protection areas. The effectiveness of nitrogen (N) management practices within organic crop rotations requires evaluation to balance yield performance with nitrate leaching...

Generalized Bell inequalities and frustrated spin systems

Abstract We find a close correspondence between generalized Bell inequalities (GBI’s) of a special kind and certain frustrated spin systems. For example, the Clauser–Horn–Shimony–Holt inequality corresponds to the frustrated square with the signs ++ + − for the nearest neighbor i...

Development and validation of a self-report questionnaire to assess executive functions in healthy adults: the executive functions in healthy adults questionnaire (EFHAQ)

Abstract Aim of this research was to develop and validate a time-efficient, ecologically valid self-report questionnaire measuring executive functions in healthy adults, grounded in the unity/diversity framework of Miyake (i.e., inhibition, updating, shifting). Across a pre-study...

When choice matters: Effects on interest and performance across mathematical problem types

Background Given the decline in students’ interest in mathematics during secondary school, autonomy-supportive interventions such as choice may help counteract this trend. Aims This study investigates the effects of within-context choice on task-specific interest and performance...
