Education, narrative technologies and digital learning : designing storytelling for creativity with computing
This book examines and illustrates the potential of narrative technology, the integration and synthesis of storytelling and digital media in education. Storytelling is a foundational and powerful process in all learning and teaching, and technology is becoming ever more ubiquitous and sophisticated, particularly in its capabilities to mediate and augment creative storytelling. The book begins with a foundational analysis of narrative use in education today, and provides a history of the emergence of narrative technology. It explores how the convergence of high-potential computing and storytelling practices and techniques can be used to enhance education, in particular the design of bespoke, interactive physical learning environments. The contemporary importance of educational design is highlighted throughout the book, which concludes with the SCâEAL design-based research framework as a proposed systematic approach to the design of narrative technology in education. The book will be a valuable resource for educational designers, technologists, teachers and policymakers, especially those with an interest in the design and use of narrative technology in education. -- Back cover.

Tandem microplastic degradation and hydrogen production by hierarchical carbon nitride-supported single-atom iron catalysts
Microplastic pollution, an emerging environmental issue, poses significant threats to aquatic ecosystems and human health. In tackling microplastic pollution and advancing green hydrogen production, this study reveals a tandem catalytic microplastic degradation-hydrogen evolution reaction (MPD-HER) process using hierarchical porous carbon nitride-supported single-atom iron catalysts (FeSA-hCN). Through hydrothermal-assisted Fenton-like reactions, we accomplish near-total ultrahigh-molecular-weight-polyethylene degradation into C

organics with 64% selectivity of carboxylic acid under neutral pH, a leap beyond current capabilities in efficiency, selectivity, eco-friendliness, and stability over six cycles. The system demonstrates versatility by degrading various daily-use plastics across different aquatic settings. The mixture of FeSA-hCN and plastic degradation products further achieves a hydrogen evolution of 42 μmol h

This tandem MPD-HER process not only provides a scalable and economically feasible strategy to combat plastic pollution but also contributes to the hydrogen economy, with far-reaching implications for global sustainability initiatives.
Developing sustainable strategies to tackle microplastic pollution and advance energy solutions is crucial for a green future. Here, authors designed carbon nitride-supported single-atom iron catalysts, with a tandem catalytic process, for microplastic degradation and green hydrogen production.

Bridging practice and theory: The emerging potential of Design-Based Research (DBR) for digital innovation in education
Design-based research (DBR) and cognate, practitioner-oriented methodologies have gained increased prominence in the last twenty-five years, and in particular have become established approaches for exploring how we might best optimise the potential impact of digital technologies in education. This is highlighted by the research that shows how DBR has become a mainstay, ubiquitous feature of graduate programmes in the Learning Sciences internationally (Sommerhoff et al, 2018). The Learning Sciences is a field of academic enquiry concerned with advancing our understanding of how we can innovate systematically to improve educational experiences and systems; and invariably where we are trying to exploit the novel, interactive affordances and capabilities offered by new digital technology. The increased use of design as a systematic research methodology around the world highlights its continued, and growing relevance and importance. The increasing popularity of educational design research methodologies, including DBR, owes to their potential to be both practically focused but theoretically robust. DBR, as a participatory and principled research methodology, can potentially support educational designers, innovators, policymakers and technologists to bridge practice and theory. Starting with an outline of the provenance and history of DBR methodology, this paper describes educational design research methodologies, illustrating how DBR can be employed to enhance the development of digital technologies in education.

The leadership illusion : the importance of context and connections
\"This book is about what we have called the \"leadership illusion\": the hardwired habit of writers, researchers and leaders themselves, when examining success or failure, to focus predominantly on the individual and often the context, but very rarely both. The Leadership Illusion asserts that to make sense of leadership, we have to understand at the same time the context in which leaders operate because both are inextricably interlinked. To try to understand a leader without the context is only half the tale. This book is an attempt to tell the whole story.\"--BOOK JACKET.

Characterisation of dust emissions from machined engineered stones to understand the hazard for accelerated silicosis
Engineered stones are novel construction materials associated with a recent upsurge in silicosis cases among workers in the stonemason industry. In order to understand the hazard for the short latency of lung disease among stonemasons, we simulated
real-time
dust exposure scenario by dry-machining engineered stones in controlled conditions, capturing and analysing the
respirable
dust generated for physical and chemical characteristics. Natural granite and marble were included for comparison. Cutting engineered stones generated high concentrations of very fine particles (< 1 µm) with > 80% respirable crystalline silica content, in the form of quartz and cristobalite. Engineered stones also contained 8–20% resin and 1–8% by weight metal elements. In comparison, natural stones had far lower respirable crystalline silica (4- 30%) and much higher metal content, 29–37%. Natural stone dust emissions also had a smaller surface area than engineered stone, as well as lower surface charge. This study highlighted the physical and chemical variability within engineered stone types as well as between engineered and natural stones. This information will ultimately help understand the unique hazard posed by engineered stone fabrication work and help guide the development of specific engineering control measures targeting lower exposure to respirable crystalline silica.

Different responses of larval fatty acid profiles to cryopreservation in two commercially important bivalves
Larval cryopreservation techniques have been established in Pacific oysters and Mediterranean mussels. Although initial cryopreservation protocols for both species differed slightly in Ficoll PM 70 (FIC) concentration, better post-thaw larval survivability was produced in mussels than oysters. Furthermore, the post-thaw survivability in the latter could be improved significantly by the addition of lipids and antioxidants to the cryoprotectant agent. These findings have generated a unique opportunity to investigate the cryo-functions of both endogenous and exogenous fatty acids (FAs) in bivalves as mammalian studies indicated that lipid compositions could contribute the interspecific difference in gamete and embryo cryopreservation. Our study showed that the higher survivability of post-thaw larvae in mussels (65% vs. 34% in oysters) could be attributed to their higher proportion of total polyunsaturated fatty acids (PUFAs), especially C22:6, and higher resistance of FA profiles to cryopreservation. In oysters, on the other hand, their FA profiles were very sensitive to cryopreservation, with saturated FAs and PUFAs being significantly increased (from 37 to 41%) and decreased (from 35% to ~ 32%), respectively. Although exogenous lipids could significantly improve the survivability of post-thaw oyster larvae from 34 to 51%, their supplementation did not alter the response pattern of endogenous FA profiles to cryopreservation.
