Novel Active-Feedback Device improves sleep quality in Insomnia Disorder: a randomized placebo-controlled trial
Get PDFObjectives: Insomnia disorder is a public health challenge associated with impaired cognitive functioning, reduced quality of life, and adverse mental health outcomes. This study examined the effectiveness of SleepCogni, an active-feedback device, in reducing insomnia symptom severity and improving perceived sleep quality in individuals with insomnia disorder.
Method: A two-arm, parallel-group trial design was used, with 80 participants randomized to either the experimental group or the placebo control group. Participants provided self-reported measures of insomnia severity, sleep continuity, and user experience as main outcome variables.
Results: Repeated measures analysis of variance showed that participants in the experimental group reported significantly greater improvements in insomnia symptom severity than the control group (Time × Treatment). Although the mean difference did not reach the threshold for clinical significance, 37.5% of the participants achieved this threshold within 1 week of treatment. Mixed-effects models showed significant improvements in sleep efficiency and total sleep time, based on sleep diary records. Finally, an independent samples t-test and content analysis indicated a more positive user experience in the experimental group.
Conclusion:The SleepCogni device appears to be a useful tool for improving sleep outcomes in individuals with insomnia disorder, showing effects on both insomnia severity and subjectively evaluated sleep. The SleepCogni device presents a useful intervention that might be used alone or as a complement to increase the effectiveness of existing treatments, such as cognitive behavioral therapy for insomnia
In-line monitoring of the fused filament fabrication additive manufacturing process for short fibre-reinforced composites.
Get PDFIn the present work, a combination method of acoustic emission (AE) and infrared thermography (IR) alongside
micro-computed tomography has been developed for the detection and monitoring of defects in additively
manufactured fibre-reinforced polymer matrix composites. This method allows for the detection of anomalies
and defects during the printing process and the verification of their presence in the finished printed structure
without the need for destructive testing. Furthermore, a structural assessment of these materials was performed
with tensile testing alongside IR monitoring. For both the in-line monitoring and the structural assessment, the
correlation between the printing parameters, the presence of defects and anomalies and the mechanical
properties was investigated
Social capital and Artificial intelligence readiness: the mediating role of cyber resilience and value construction of SMEs in resource-constrained environments
Get PDFDrawing on social capital theory, this study explores the antecedents of AI readiness in Small and Medium-sized Enterprises (SMEs) operating in resource-constrained environments, emphasising capabilities that mitigate cyber risks, and foster value construction in SMEs. Specifically, the study examines how structural, cognitive, and relational social capital fosters cyber resilience and contributes to proactive value construction, enhancing SMEs’ AI readiness and enabling them to construct and sustain value while safeguarding against potential cyber threats. The study adopts a Covariance-based Structural Equation Modelling (CB-SEM) approach to analyse 589 valid responses. A multi-wave data strategy with an interval cross-lagged design was implemented to reduce the risk of common method bias. The findings reveal that structural and relational capital significantly drive AI readiness, while cognitive social capital enhances cyber resilience, which is pivotal in constructing and protecting organisational value. Moreover, cyber resilience mediates the relationship between cognitive social capital and AI readiness, and enabling value construction amid cyber-related disruptions. SMEs with robust social capital networks are better equipped to leverage AI technologies for innovation and growth, construct new value streams, and defend against cyber risks, securing value in dynamic digital environments. This study contributes to the growing discourse on cybersecurity and digital transformation by offering insights into how SMEs can bolster digital innovation and construct sustainable value in the face of mounting cyber risks
What is an urban just transition? Grappling with an unsettled concept in an industrial region
Get PDFAs global decarbonisation pressures grow, so do calls for ‘just transition’. Urban and regional governments are exploring what this means for their jurisdictions. This article investigates how urban policy makers make sense of just transition, and the implications for its understanding in urban policy. We adopt Q-methodology to examine sensemaking for policy stakeholders in a UK industrial region, producing a new analytical conception of sensemaking through conceptualisation, contextualisation and operationalisation. This allows interrogation of how unsettled concepts like just transition are translated into legible policy entities. We found participants wrestled to resolve just transition with path-dependent narratives, reaching for existing policy discourses to modify just transition. As sensemaking moved through different stages existing narratives layered up, reducing transformative potential. Collectively, these suggest openness to just transition as policy logic but a challenge to embed transformational approaches. Cognitive and cultural dependencies are central to this challenge and our findings point to specific ways these dependencies are manifest
Exploring Mechanistic Details and Catalyst Resilience in Electrocatalytic Water Oxidation With a Cu(II) Complex Bearing a Redox‐Active Ligand
No full textHerein, we report that a copper complex [Cu(dpaq)](ClO4) (1) (H-dpaq = 2-[bis(pyridin-2-ylmethyl)]amino-N-quinolin-8-yl-acetamide) acts as a molecular water oxidation catalyst (WOC) under strong basic condition. Complex 1 oxidizes water to dioxygen in 0.1 M phosphate buffer solution at pH 12.0, exhibiting a turnover frequency of 3.1 × 102 s−1 at a low overpotential (η) of ∼550 mV versus NHE at 1 mA cm−2. A turnover number of 4.0 can be obtained during controlled potential electrolysis (CPE) using 0.25 mM complex 1 at a potential of 1.5 V at pH 12.0 for 3 h. Postelectrolysis analysis, rinse tests, and chelating assays collectively support the homogeneous nature of the electrocatalyst. Mechanistic investigations and quantum chemical calculations reveal a pathway wherein two successive ligand-centered oxidations transform the catalyst into a Cu(II)(dpaq•)O•. intermediate. Absence of any metal centered oxidation renders the oxidized intermediate less electrophilic, resulting in the survival of the methylene groups present on the ligand backbone against oxidation. The formation of the O─O bond is proposed to proceed via two consecutive single electron transfers (SET) from incoming hydroxide ions to the formal CuIV–oxo species
The Learn Together programme (part B): evaluating co-designed guidance to support patient and family involvement in patient safety incident investigations
Get PDFBackground: Expectations of patient and family involvement in investigations of healthcare harm are becoming conventional. Nonetheless, how people should be involved, is less clear. Therefore, the “Learn Together” guidance was co-designed, aiming to provide practical and emotional support to investigators, patients and families.
Aim: To longitudinally evaluate use of the Learn Together guidance in practice—designed to support patient and family involvement in investigations of healthcare harm.
Methods: A 15-month process evaluation took place across five sites, following 29 investigations in which the Learn Together guidance was used. Sites comprised two mental health and two physical health hospital Trusts, and an independent maternity investigatory body in England. Longitudinally, 127 interviews were conducted with investigators, patients, families, staff, and management. Interview and observational data were synthesized using Pen Portraits and analyzed using multi-case thematic analysis.
Findings: The guidance supported the systematic involvement of patients and families in investigations of healthcare harm and informed them how, why, and when to be involved across settings. However, within hospital Trusts, investigators often had to conduct “pre-investigations” to source appropriate details of people to contact, juggle ethical dilemmas of involving vs. re-traumatizing, and work within contexts of unclear organizational processes and responsibilities. These issues were largely circumvented when investigations were conducted by an independent body, due to better established processes, infrastructure and resources, however independence did introduce challenge to the rebuilding of relationships between families and the hospital Trust. Across settings, the involvement of patients and families fluctuated over time and sharing a draft investigation report marked an important part of the process—perhaps symbolic of organizational ethos surrounding involvement. This was made particularly difficult within hospital Trusts, as investigators often had to navigate systemic barriers alone. Organizational learning was also a challenge across settings.
Conclusions: Investigations of healthcare harm are complex, relational processes that have the potential to either repair, or compound harm. The Learn Together guidance helped to support patient and family involvement and the evaluation led to further revisions, to better inform and support patients, families and investigators in ways that meet their needs (https://learn-together.org.uk). In particular, the five-stage process is designed to center the needs of patients and families to be heard, and their experiences dignified, before moving to address organizational needs for learning and improvement. However, as a healthcare system, we call for more formal recognition, support and training for the complex challenges investigators face—beyond clinical skills, as well as the appropriate and flexible infrastructure to enable a receptive organizational culture and context for meaningful patient and family involvement
The Development and (Mis)appropriation of a Digital Kit for Jewellers
Get PDFJewellers’ participation in interaction design is scarce, yet the creativity of jewellers could add value as they interpret materials and mediate personal connections in poetic ways. We investigate how to empower jewellers to experiment with the possibilities that physical computing offers to their practice. This paper presents the making of a Digital Jewellery Kit, a composite of pre-assembled circuitry, used by second-year BA jewellery students during a 10-week project which brought together theory and practice. Drawing on students’ reflective accounts, we discuss what made the jewellers’ path into physical computing more meaningful to their practice, what type of artefacts they created with electronics as well as what values drove their creative process. We offer design recommendations on how to support the praxes of jewellers whilst allowing their creativity to grow through their new understanding of physical computing and contribute to the discussions around hybrid craft within HCI and educational contexts
