A Constructivist Grounded Theory Study on Mental Health Recovery from a Lived Experience Perspective in Singapore
Authors: Kuek Jonathan Han Loong , Raeburn Toby , Chow Melissa Yan Zhi , Wand Timothy 
Published: September 2023

AbstractMore contemporary personal recovery conceptualisation of mental health recovery emphasize the need to consider the perspectives of people who experience mental ill-health. Most lived experience research has been done in Western cultures with relatively few studies in Asian ones, creating a gap that needs to be addressed due to differences in cultural worldviews. This study explores the notion of recovery from the lens of people experiencing mental health challenges in Singapore. We adopted a constructivist grounded theory perspective to evaluate qualitative data from 21 participants. The core category which best represented what recovery meant was “reconciling and living with experiences of mental ill-health”. Our findings suggest that a variety of societal aspects greatly influence perceptions of mental health recovery in Singapore, as participants often shared their desire to live a meaningful life within society but could only do so if they found a way to manage their symptoms more effectively.

Published: September 2023

Abstract
Early childhood education and care (ECEC) institutions are considered contexts wherein physical activity (PA) can be effectively promoted. Some approaches have been used in the early childhood setting to identify how teachers incorporate movement opportunities into the ECEC curriculum. However, studies are still scarce regarding pedagogical content knowledge (PCK) of structured and non-structured movement possibilities in toddler education (1–3 years old). Taking into account that working with toddlers requires specific training and sensitivity, the aim of the study was to assess ECEC educators’ and student teachers’ perceptions of what they know, how they transmit it, what kind of curricular practices they execute, and the didactic implications of movement opportunities in toddler education. This was an exploratory qualitative research study, in which open-ended, semi-structured qualitative interviews, plus qualitative content analysis of a written questionnaire, were conducted with 14 educators and 20 student teachers. Our results show that educators and students distinguish PCK in the different curricular practices related to movement, identifying differences between structured PA opportunities and free play opportunities. Educators and student teachers identified different sources of knowledge, barriers, and facilitators of structured movement opportunities in the ECEC toddler context, and they recognized that PA is important to young children’s development; however, little knowledge of PA guidelines to promote it was evident. Our findings contribute to understanding educators’ perceptions regarding movement as a curricular practice for children aged 1 to 3 years. Educators and public administration could find structured PA to be a complement to a harmonious development from a young age.
Prequestioning and Pretesting Effects: a Review of Empirical Research, Theoretical Perspectives, and Implications for Educational Practice
Authors: Pan Steven C. , Carpenter Shana K. 
Published: September 2023

Abstract Testing students on information that they do not know might seem like a fruitless endeavor. After all, why give anyone a test that they are guaranteed to fail because they have not yet learned the material? Remarkably, a growing body of research indicates that such testing—formally known as prequestioning or pretesting—can benefit learning if there is an opportunity to study the correct answers afterwards. This prequestioning effect or pretesting effect has been successfully demonstrated with a variety of learning materials, despite many erroneous responses being generated on initial tests, and in conjunction with text materials, videos, lectures, and/or correct answer feedback. In this review, we summarize the emerging evidence for prequestioning and pretesting effects on memory and transfer of learning. Uses of pre-instruction testing in the classroom, theoretical explanations, and other considerations are addressed. The evidence to date indicates that prequestioning and pretesting can often enhance learning, but the extent of that enhancement may vary due to differences in procedure or how learning is assessed. The underlying cognitive mechanisms, which can be represented by a three-stage framework, appear to involve test-induced changes in subsequent learning behaviors and possibly other processes. Further research is needed to clarify moderating factors, theoretical issues, and best practices for educational applications.
Eikonal Quasinormal Modes, Photon Sphere and Shadow of a Charged Black Hole in the 4D Einstein-Gauss-Bonnet Gravity
Authors: Ladino Jose Miguel , Larrañaga Eduard 
Published: September 2023

AbstractIn this work, we investigate the relationship between the geometrical properties, the photon sphere, the shadow, and the eikonal quasinormal modes of electrically charged black holes in 4D Einstein-Gauss-Bonnet gravity. Quasinormal modes are complex frequency oscillations that are dependent on the geometry of spacetime and have significant applications in studying black hole properties and testing alternative theories of gravity. Here, we focus on the eikonal limit for high frequency quasinormal modes and their connection to the black holes geometric characteristics. To study the photon sphere, quasinormal modes, and black hole shadow, we employ various techniques such as the Wentzel-Kramers-Brillouin method in various orders of approximation, the Poschl-Teller potential method, and Churilova’s analytical formulas. Our results indicate that the real part of the eikonal quasinormal mode frequencies of test fields are linked to the unstable circular null geodesic and are correlated with the shadow radius for a charged black hole in 4D Einstein-Gauss-Bonnet gravity. Furthermore, we found that the real part of quasinormal modes, the photon sphere and shadow radius have a lower value for charged black holes in 4D Einstein-Gauss-Bonnet gravity compared to black holes without electric charge and those of static black holes in general relativity. Additionally, we explore various analytical formulas for the photon spheres and shadows, and deduce an approximate formula for the shadow radius of charged black holes in 4D Einstein-Gauss-Bonnet gravity, based on Churilova’s method and its connection with the eikonal quasinormal modes.

Published: September 2023

Abstract
Purpose
The aim of the present study was to explore the meaning of work for the subjective well-being of autistic adults with and without paid (competitive) employment and to evaluate the differences and similarities between these groups.

Methods
Eight focus groups were conducted, including a total of 64 autistic adults. Four groups entailed participants with current paid employment (including part-time) and four groups entailed participants without paid employment. All discussions were audiotaped and transcribed verbatim to enable inductive thematic content analysis. Data were analyzed using ATLAS.ti 9.

Results
Generally, both groups viewed paid employment as very important for well-being, albeit for different reasons. Three themes were found: (1) Not having paid employment was associated with lacking societal recognition, and subsequent low self-esteem, which was a dominant theme in those without work; (2) Work can seriously damage (mental) health and well-being, found in both groups; and (3) Paid employment provides many benefits for well-being, with subthemes: ‘purpose,’ ‘social contacts,’ ‘growth and use of talents,’ ‘structure and calmness,’ and ‘income and freedom’, which was a dominant theme in those with paid employment.

Conclusions
Both groups found paid employment highly important for their well-being, albeit for different reasons. However, both also agreed that paid employment can be very harmful to (mental) health and well-being. Suitable, well-supported jobs are important for well-being, may help to buffer stress in other life areas, and may even prevent autistic burnout. More studies are needed on how healthy jobs can be created where autistic individuals get positive energy and experience high well-being. This will also help to reduce socio-economic inequality.
Identifying bridges prone to instream wood accumulation: insights from bridges across the UK

Published: September 2023

AbstractAccumulation of instream large wood (i.e., fallen trees, trunks, branches, and roots) at bridges during floods may exacerbate flooding, scour and cause structural failure. Yet, explaining and predicting the likelihood of a bridge trapping wood remains challenging. Quantitative data regarding wood accumulation at bridges are scarce, and most equations proposed to estimate the accumulation probability were derived from laboratory experiments, and include variables such as flow velocity, Froude number, and approaching wood volume or size which are difficult to obtain. Other evaluations based on technical reports and information regarding wood removal have been proposed but are mostly qualitative. Until now, a data-driven approach combining multiple quantitative accessible variables at the river reach and catchment scales remains lacking. As a result, the controlling parameters explaining whether a bridge is prone to trap wood are still unclear. This work aims to fill this gap by analysing a database of 49 bridges across the United Kingdom (UK) classified as prone and not prone to wood accumulation. The database contained information regarding the geometry of the bridge (i.e., number of piers and pier shape) and we added parameters describing the upstream river channel morphology, the riparian landcover, and high-flow characteristics. We applied multivariate statistics and a machine learning approach to identify the variables that explained and predicted the predisposition of bridges to wood accumulation. Results showed that the number of bridge piers, the unit stream power, the pier shape, and the riparian forested area explained 87% of the total variability for the training dataset (0.87 training accuracy), and the selected model had a testing accuracy of 0.60 (60%). Although limited by the sample size, this study sheds light on the identification of bridges prone to wood accumulation and can inform bridge design and management to mitigate wood-related hazards.
Intermediate activities while commuting
Authors: Giménez-Nadal José Ignacio , Molina José Alberto , Velilla Jorge 
Published: September 2023

AbstractRecent analyses have shown that commutes to and from work are not symmetric, suggesting that intermediate activities are at the root of the asymmetries. However, to model how these activities accumulate and interact within trips to and from work is a methodologically unexplored issue. We analyze the intermediate activities done while commuting, using data from the American Time Use Survey for the period 2003–2019. We show that commuting as defined in Time Use Surveys is underestimated, with significant differences that depend on whether intermediate activities are considered. Such differences are especially important in commuting from work to home and reveal gender differences. Our results contribute to the analysis of commuting behavior by proposing new identification strategies based on intermediate non-trip episodes, and by showing how commuting interacts with other non-commuting activities. We also explore intermediate episodes during commuting, which may partially explain gender differences in commuting time.
Asymptotic expansion of an estimator for the Hurst coefficient
Authors: Mishura Yuliya , Yamagishi Hayate , Yoshida Nakahiro 
Published: September 2023

AbstractAsymptotic expansion is presented for an estimator of the Hurst coefficient of a fractional Brownian motion. We first derive the expansion formula of the principal term of the error of the estimator using a recently developed theory of asymptotic expansion of the distribution of Wiener functionals, and utilize the perturbation method on the obtained formula in order to calculate the expansion of the estimator. We also discuss some second-order modifications of the estimator. Numerical results show that the asymptotic expansion attains higher accuracy than the normal approximation.
Augmented reality for sentinel lymph node biopsy

Published: September 2023

Abstract
Introduction
Sentinel lymph node biopsy for oral and oropharyngeal squamous cell carcinoma is a well-established staging method. One variation is to inject a radioactive tracer near the primary tumor of the patient. After a few minutes, audio feedback from an external hand-held $$\gamma $$
γ
-detection probe can monitor the uptake into the lymphatic system. Such probes place a high cognitive load on the surgeon during the biopsy, as they require the simultaneous use of both hands and the skills necessary to correlate the audio signal with the location of tracer accumulation in the lymph nodes. Therefore, an augmented reality (AR) approach to directly visualize and thus discriminate nearby lymph nodes would greatly reduce the surgeons’ cognitive load.

Materials and methods
We present a proof of concept of an AR approach for sentinel lymph node biopsy by ex vivo experiments. The 3D position of the radioactive $$\gamma $$
γ
-sources is reconstructed from a single $$\gamma $$
γ
-image, acquired by a stationary table-attached multi-pinhole $$\gamma $$
γ
-detector. The position of the sources is then visualized using Microsoft’s HoloLens. We further investigate the performance of our SLNF algorithm for a single source, two sources, and two sources with a hot background.

Results
In our ex vivo experiments, a single $$\gamma $$
γ
-source and its AR representation show good correlation with known locations, with a maximum error of 4.47 mm. The SLNF algorithm performs well when only one source is reconstructed, with a maximum error of 7.77 mm. For the more challenging case to reconstruct two sources, the errors vary between 2.23 mm and 75.92 mm.

Conclusion
This proof of concept shows promising results in reconstructing and displaying one $$\gamma $$
γ
-source. Two simultaneously recorded sources are more challenging and require further algorithmic optimization.

Published: September 2023

Zusammenfassung
Hintergrund
Die Gesundheitsförderung und präventive Krisenprophylaxe sind fundamentaler Bestandteil derzeitiger Mental-Health-Strukturen. Recovery-Colleges, als Institutionen zur Förderung seelischer Gesundheit, leisten in Deutschland bereits einen wesentlichen Beitrag zur mentalen Gesundheitsförderung und individuellen Recovery. Mittlerweile hat sich aus einzelnen Projektstrukturen ein deutschlandweites Netzwerk gebildet.

Zielsetzung
Die vorliegende Übersichtsarbeit beschäftigt sich mit dem bisher noch nicht abgebildeten, aktuellen Umsetzungsstand der Etablierung und primären Verortung von Recovery-College-Strukturen (RC/EC) im deutschsprachigen Raum. Es werden grundlegende Aspekte, Inhalte und Strukturen zum Recovery-College-Konzept und dessen Herkunft aufgezeigt. Dabei werden unterschiedliche Projektmodelle, deren Ausprägungen und Besonderheiten betrachtet.

Material und Methoden
Aufbauend auf eine Literaturrecherche über die Plattform PubMed zum Thema Recovery-Colleges konnten mittels Online-Befragung über das deutsche RC-Netzwerk (RCN) 11 verschiedene College-Einrichtungen rekrutiert und befragt werden.

Ergebnisse
Die Auswertung zeigt, dass die College-Einrichtungen nach gleichen Prinzipien strukturiert sind, aber sich z. B. in ihrem Standort, ihrer Refinanzierung und in ihrem Leistungsspektrum an Kursangeboten unterscheiden können. Des Weiteren stehen College-Einrichtungen oft in direkter oder indirekter Verbindung zu professionellen Akteuren des Gesundheitswesens, haben aber auch Anbindungen zu gemeindenahen Einrichtungen, Lehreinrichtungen und Selbsthilfegruppen.

Schlussfolgerung
Letztlich bedarf es einer verstärkten Aufmerksamkeit, einer kontinuierlichen finanziellen Rahmensubventionierung und weiterer Erforschung, um eine recovery-orientierte Praxis mit dem College-Konzept in Deutschland zu etablieren.
SIRT3 Regulates the ROS-FPR1/HIF-1α Axis under Hypoxic Conditions to Influence Lung Cancer Progression

Published: September 2023

AbstractHypoxia-inducible factor (HIF-1α) is a therapeutic target in lung cancer, and the deacetylase sirtuin 3 (SIRT3) is closely associated with tumorigenesis. Formyl peptide receptor 1 (FPR1) is involved in a wide range of physiopathological processes in various tumor cells. We explored whether SIRT3 affects the development of lung cancer by regulating the reactive oxygen species (ROS)-FPR1/HIF-1α axis under hypoxic conditions. The effects of SIRT3 overexpression on the levels of FPR1, HIF-1α, ROS, inflammatory factors, and cell proliferation and migration in A549 cells under hypoxic conditions were assessed in combination with the FPR1 inhibitor. BALB/c nude mice were subcutaneously injected with cancer cells transfected/untransfected with SIRT3 overexpressing lentiviral vectors. Immunohistochemistry and enzyme-linked immunosorbent assay were performed to detect SIRT3 expression and the expression levels of IL-1β, TNF-α, and IL-6, respectively, in tumor tissues. Cell proliferation, invasion, migration, and IL-1β, TNF-α, IL-6, and ROS levels were significantly higher in the Hypoxia group than in the Control group. Moreover, the mRNA and protein expression levels of SIRT3 were significantly down-regulated, whereas they were significantly up-regulated for FPR1 and HIF-1α. In contrast, SIRT3 overexpression in a hypoxic environment inhibited cell proliferation, invasion, and migration, decreased IL-1β, TNF-α, IL-6, and ROS levels, up-regulated the mRNA and protein expression levels of SIRT3, and down-regulated the mRNA and protein expression levels of FPR1 and HIF-1α. In addition, we found the same results in tumorigenic experiments in nude mice. SIRT3 in hypoxic environments may affect tumor cell proliferation, invasion, migration, and inflammation levels via the ROS-FPR1/HIF-1α axis, thereby inhibiting tumor cell development.
Inorganic A-site cations improve the performance of band-edge carriers in lead halide perovskites
Authors: Wang Cheng , Rong Yaoguang , Wang Ti 
Published: September 2023

AbstractIn lead halide perovskites, organic A-site cations are generally introduced to fine-tune the properties. One of the questions under debate is whether organic A-site cations are essential for high-performance solar cells. In this study, we compare the band edge carrier dynamics and diffusion process in MAPbBr3 and CsPbBr3 single-crystal microplates. By transient absorption microscopy, the band-edge carrier diffusion constants are unraveled. With the replacement of inorganic A-site cations, the diffusion constant in CsPbBr3 increases almost 8 times compared to that in MAPbBr3. This work reveals that introducing inorganic A-site cations can lead to a much larger diffusion length and improve the performance of band-edge carriers.

Community deception in directed influence networks
Authors: Madi Saif Aldeen , Pirrò Giuseppe 
Published: September 2023

AbstractCommunity deception is about protecting users of a community from being discovered by community detection algorithms. This paper studies community deception in directed influence network (DIN). It aims to address the limitations of the state of the art through a twofold strategy: introducing directed influence and considering the role of nodes in the deception strategy. The study focuses on using modularity as the optimization function. It offers several contributions, including an upgraded version of modularity that accommodates the concept of influence, edge-based, and node-based deception algorithms.. The study concludes with a comparison of the proposed methods with the state of the art showing that not only influence is a valuable ingredient to devising deception strategies but also that novel deception approaches centered on node operations can be successfully devised.
Making Trust Safe for AI? Non-agential Trust as a Conceptual Engineering Problem
Authors: Viehoff Juri 
Published: September 2023

AbstractShould we be worried that the concept of trust is increasingly used when we assess non-human agents and artefacts, say robots and AI systems? Whilst some authors have developed explanations of the concept of trust with a view to accounting for trust in AI systems and other non-agents, others have rejected the idea that we should extend trust in this way. The article advances this debate by bringing insights from conceptual engineering to bear on this issue. After setting up a target concept of trust in terms of four functional desiderata (trust-reliance distinction, explanatory strength, tracking affective responses, and accounting for distrust), I analyze how agential vs. non-agential accounts can satisfy these. A final section investigates how ‘non-ideal’ circumstances—that is, circumstances where the manifest and operative concept use diverge amongst concept users—affect our choice about which rendering of trust is to be preferred. I suggest that some prominent arguments against extending the language of trust to non-agents are not decisive and reflect on an important oversight in the current debate, namely a failure to address how narrower, agent-centred accounts curtail our ability to distrust non-agents.
