A balance between stability and flexibility: Adaptive patterns of self‐regulated learning processes shape game‐based learning

British Journal of Educational Technology, EarlyView.
Abstract To ensure learning efficiency in game‐based learning (GBL), learners must regulate cognitive, affective, metacognitive and motivational (CAMM) processes, collectively known as self‐regulated learning (SRL). SRL is dynamic and non‐linear, characterized by regulatory patterns and CAMM interactions that lead to macro‐level SRL behaviours. In this

Closed-Loop Koopman Operator Approximation [PDF]

This paper proposes a method to identify a Koopman model of a feedback-controlled system given a known controller. The Koopman operator allows a nonlinear system to be rewritten as an infinite-dimensional linear system by viewing it in terms of an ...

Closing Trajectories: Equation‐Free Cyclic Animation via Koopman Surrogates

Computer Graphics Forum, EarlyView.
Abstract Cyclic animation is widely used in computer graphics and interactive content. It supports seamless playback in games, VR, and interactive simulation, where short clips must repeat smoothly over long durations. Converting an observed non‐cyclic trajectory into a seamless loop is challenging because the endpoint states of the observed sequence ...

Introduction to the Koopman operator in Systems and Control

, 2018
The Koopman operator is a linear, infinite-dimensional operator defined for a nonlinear dynamical system. Through this linear operator, we can exploit established linear techniques (e.g.

Balancing Standardisation and Individualisation in Psychosocial Interventions for Perinatal Bereavement: Bereaved Parents' Perspectives From a Qualitative Study

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aim To explore bereaved parents' experiences of receiving psychosocial interventions (PSIs) in hospital‐based perinatal bereavement care in Ireland. Design Descriptive qualitative study. Methods Fifteen bereaved parents (13 mothers and 2 partners) whose loss occurred within the past three years were recruited via a national parent‐led charity.

Post‐release survival, movement and marine migration of smolt‐to‐adult supplemented Atlantic Salmon

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) populations are declining across much of their range, prompting the use of supplementation strategies, such as smolt‐to‐adult supplementation (SAS), to enhance adult returns. However, little is known about how captivity while maturing to adulthood influences post‐release survival, behaviour and migration of ...

Religious Pluralism and Social Networks: How Exposure to Religious Pluralism Through Social Ties Influences Baptism Decisions

Journal for the Scientific Study of Religion, EarlyView.
ABSTRACT A longstanding debate in the sociology of religion has focused on how religious pluralism affects religious participation. Existing research shows mixed findings, often relying on macro‐level measures that overlook how individuals are actually exposed to religious pluralism in their lives. This study shifts focus to the meso‐level by examining
