Trust in complex task environments: results of an agent-based simulation on incomplete contracts

Purpose Incentive contracts often do not govern all task elements for which a subordinate is responsible. In these situations, trust among the contracting parties is crucial for the effort the subordinate exerts on non-contracted task elements. This paper aims to examine the emer...

Sample-Based Consistency in Infinite-Dimensional Conic-Constrained Stochastic Optimization

Abstract. This paper is concerned with a class of stochastic optimization problems defined on a Banach space with almost sure conic-type constraints. For this class of problems, we investigate the consistency of optimal values and solutions corresponding to sample average approxi...

Pattern of ovarian cancer recurrence and survival: final analysis of an extended cohort of 591 patients

Summary This study reports the results of the extended final analysis of the pattern of recurrence and factors influencing survival in 591 consecutive patients with recurrent primary ovarian cancer. Recurrence was arbitrarily defined as the first clinical manifestation of tumor p...

A Two-Stage Framework for Sports Betting Asset Construction: Probabilistic Prediction and Risk-Aware Portfolio Allocation

This manuscript presents a two-stage framework that treats sports betting markets as an alternative asset class, coupling probabilistic prediction with risk-aware portfolio allocation. The first stage produces calibrated probabilistic forecasts of match outcomes using heterogeneo...

Structural validity and measurement invariance of the WHO-5 Well-Being Index among young adolescents in a family-focused prevention context in Southeastern Europe

Abstract Background The World Health Organization Five Well-Being Index (WHO-5) is a widely used, open-access measure of subjective well-being. However, evidence on its psychometric properties among young adolescents participating in preventive interventions in low- and middle-in...

Competing business models in international higher education: a transatlantic comparison

Abstract International higher education is being reorganized by competition between business models rather than by competition between national systems alone. This Brief argues that the long-standing U.S. advantage in attracting international students and scientific talent is inc...

Decoding Innovation in Circular Economy: Investigating Policy Pathways for the European Union

The transition from a linear to a circular economy has become a strategic priority for achieving sustainable development, resource efficiency, and economic resilience. However, empirical evidence on the determinants of circular economy innovation (CEI) remains limited, particular...

Comics as a tool for teaching alternative energy: effects on cognitive achievement, motivation, attitudes, and learning environment among sixth-grade students

This study examined the effects of comic-based instruction in an alternative energy unit on sixth-grade students’ cognitive achievement, science learning motivation, attitudes toward alternative energy, and perceptions of the classroom learning environment. The study responded to...

A Cournot–Nash model for a coupled hydrogen and electricity market

Abstract We present a novel model of a coupled hydrogen and electricity market on the intraday time scale, where hydrogen gas is used as a storage device for the electric grid. Electricity is produced by renewable energy sources or by extracting hydrogen from a pipeline that is s...

Symbolic Capital or Social Glue? Recognition in Collaborative High-Energy Physics Research

A trend towards more and larger research collaborations in the sciences raises questions about how individual scientists who work primarily in collaborations receive recognition. Experimental high-energy physics is known for exceptionally large research collaborations, with publi...

Differences in the Thoracolumbar Fascia Between Low Back Pain Patients and Healthy Individuals: A Systematic Review with Meta-Analysis

Abstract Background In view of new evidence revealing a mechanical and nociceptive role of the thoracolumbar fascia (TLF), it has been suggested to be involved in low back pain. Objective To compare characteristics of the TLF in low back pain (LBP) patients and asymptomatic contr...

Maternal BMI modulates cord plasma NT-proBNP in gestational diabetes linking cardiac stress to insulin-cortisol crosstalk

Abstract Gestational diabetes mellitus (GDM) is an increasingly prevalent pregnancy disorder associated with adverse maternal and neonatal outcomes, including an increased risk of early-onset cardiovascular disease in infants. GDM is associated with cardiac structural and functio...

Developing Empathy Quest: A Digital Game Based Learning Tool About Teachers’ Emotional Intelligence

Socio-emotional skills are essential for teachers’ wellbeing, classroom functioning, and promotion of students’ social–emotional development. Digital game-based learning (DGBL) represents a promising approach to promote these competencies through engaging and experiential learnin...
