AbstractBefore taking full responsibility for a real classroom, pre-service teachers (PTs) can safely experience a rich learning atmosphere in a simulated virtual classroom environment and receive feedback on their lesson planning and teaching performance. This research aims to support and examine the process of structuring PTs’ teaching skills with a multi-source feedback system integrated with simulation-based teacher training (SimInTeach-FBS). A phenomenological approach was employed in order to understand the nature of PT’s experiences from a feedback system focusing on teaching skills. Seventy PTs, twelve mentor teachers (MTs), and six teacher educators (TEs) participated in the study. Various data collection tools were used to gain a deeper understanding of the participants' experiences: reflective journals, open-ended feedback forms, and observation notes. The results of the content analysis showed that teaching experience with SimInTeach-FBS raises self-awareness and improves PTs’ teaching skills. It was revealed that teaching skills were mutually structured, feedback given to the PTs multiplied the effect of the development process, and teaching experience facilitated the transfer of acquired teaching skills to real life.

Published: April 2024

AbstractNested in the socio-cultural theory and the related concepts of dialogue in thinking (Mercer & Littleton, 2007) and dialogic teaching in classrooms (Mercer & Howe, 2012), this study explored knowledge and technology as dynamic meaning-making processes in Norwegian early childhood education and care (ECEC) settings. Group-reflections from thirteen Norwegian early childhood educators and their ontological beliefs concerning digital technology in ECEC were analysed with a theory-driven thematic analysis. The analysis highlights two tensions between individual and collective reasons for using digital technology in ECEC: a tension between the educators’ ontological beliefs about the need for children’s collective experiences and children’s individual use of digital technology, and another tension related to the educators’ own individual learning and collective knowledge construction about technology. We derive time as the key reason for the individual-collective tensions. Educators need time to develop good experiences with digital technology for all children, and they need time to develop their own learning, individually and collectively. Given the urgent demand to support technology use in Norwegian ECEC for young children, we underscore time constraints as a key factor influencing individual-collective tensions, impacting educators’ capacity for effective implementation and professional development.
Expressive Power and Intensional Operators
Authors: Cubides Kovacsics Pablo , Rey David 
Published: April 2024

AbstractIn Entities and Indices, M. J. Cresswell argued that a first-order modal language can reach the expressive power of natural-language modal discourse only if we give to the formal language a semantics with indices containing infinite possible worlds and we add to it an infinite collection of operators $${{\varvec{actually}}}_n$$

actually

and $$ Ref _n$$

which store and retrieve worlds. In the fourth chapter of the book, Cresswell gave a proof that the resulting intensional language, which he called $${\mathscr {L}}^*$$

L

∗

, is as expressive as an extensional variant of it, called $${\mathscr {L}}$$
L
, which has full quantification over worlds. In both linguistics and philosophy, Cresswell’s book has been viewed as offering a compelling argument for preferring extensional systems in the study of natural language. In this paper, after providing a model-theoretic definition of the relation being as expressive as that can be applied to Cresswell’s languages $${\mathscr {L}}$$
L
and $${\mathscr {L}}^*$$

L

, we show that the intensional language $${\mathscr {L}}^*$$

L

is not as expressive as the extensional language $${\mathscr {L}}$$
L
. This result, we claim, undermines Cresswell’s argument to the effect that English modal discourse has the power of explicit quantification over worlds. Additionally, we show that $${\mathscr {L}}^*$$

L

does become as expressive as $${\mathscr {L}}$$
L
when we add Cresswell’s operator of universal modality $$\square $$

to $${\mathscr {L}}^*$$

, which provides an extra amount of expressive power. Recently, I. Yanovich has advocated a view that is similar to ours in important respects. At the end of the paper we offer a short discussion of his formalism.

Published: April 2024

AbstractGlass-nanocomposites (GNCs) samples of composition [(100−x) Li2B4O7–xPbTiO3] with x = 5, 10, 15 and 20 mol% were prepared by melt quenching method. The two phases of the GNCs samples, a glassy phase and PbTiO3 nanoparticles/clusters phase, can be seen in the energy dispersive X-ray spectra and scanning electron microscopic micrographs. Fourier transformation infrared spectra of the GNCs samples exhibited bands due to triangular with NBO’s and tetrahedral borate groups. Additionally, the Ti4+ ions exist in both TiO4 and TiO6 structural units while the Ti3+ ions exist in TiO6 structural units. The electron spin resonance (ESR) spectra of the GNCs samples exhibit two ESR signals, broad and narrow, corresponding to the Ti3+ (3d1) ions in both tetragonal deformed octahedral and in the other structural configuration, respectively. The optical transmission spectra of the GNCs samples exhibited three transmission bands, 3Γ5 → 2Γ3, 2B2g → 2B1g and 2B2g → 2A1g transitions, in the visible region. The variation in optical band gap (Eopt) with increasing PbTiO3 content were due to the conversion between BO3 with NBOs and BO4 units as well as the reduction of Ti4+ to Ti3+ ions in the GNCs matrix. These results demonstrate that the present GNCs may be used for practical applications such as optical devices.
Synchronization of two indirectly coupled singly resonant optical parametric oscillators
Authors: Mahmoud M. S. , Medhat M. , El-Nashar Hassan F. 
Published: April 2024

AbstractWe analyse a system of a singly resonant optical parametric oscillator for a second order nonlinear material. First, we show that the dynamics of the resonating cavity signal mode can be expressed by a Stuart–Landau oscillator, for a certain pumping powers close to the threshold. Second, we couple two optical parametric oscillators indirectly via a cold resonator. When the condition of a weak coupling is satisfied, the limit-cycle of each oscillator is unaltered, and the system is described by a coupled phase oscillator model (Kuramoto model), where a frequency synchronization of the two oscillators occurs at a critical coupling constant.

Published: April 2024

Abstract
The increase in cases of various cancers, the number of cancer patients, and the serious side effects of current chemical treatments have encouraged researchers to discover novel and more effective drugs from plant sources. In this review, PubMed and Scopus were searched for English-language peer-reviewed articles published since 1994, using the keywords: Medicinal plants, Egypt, and Cancer. The inclusion criteria for this systematic review were English peer-reviewed original research articles. A total of 286 studies were included. Studies have shown that the active compounds in certain plants can have anticancer activities by various mechanisms, such as cell cycle arrest, apoptosis induction, and antioxidant effects. Additionally, it is evident that medicinal plants can act as inhibitors of cancer cells. Plants can also act as immune checkpoint inhibitors, which inhibit proteins such as PD-L1 on tumor cells, PD-1 and CTLA-4 on T cells, and help to regulate immune responses. This review also discusses the efficacy of nanoparticles of these plants against cancer cells. The findings indicate the high potential of investigating the bioactive anticancer components of Egyptian medicinal plants for advancing novel treatments that are more effective in combating cancer. The extracts and active compounds of the medicinal plants detailed in this review could provide the foundation for further clinical trials to be conducted, to develop new anticancer drugs.
Understanding the influence of different proxy perspectives in explaining the difference between self-rated and proxy-rated quality of life in people living with dementia: a systematic literature review and meta-analysis
Authors: Engel Lidia , Sokolova Valeriia , Bogatyreva Ekaterina , Leuenberger Anna 
Published: April 2024

Abstract
Purpose
Proxy assessment can be elicited via the proxy-patient perspective (i.e., asking proxies to assess the patient’s quality of life (QoL) as they think the patient would respond) or proxy-proxy perspective (i.e., asking proxies to provide their own perspective on the patient’s QoL). This review aimed to identify the role of the proxy perspective in explaining the differences between self-rated and proxy-rated QoL in people living with dementia.

Methods
A systematic literate review was conducted by sourcing articles from a previously published review, supplemented by an update of the review in four bibliographic databases. Peer-reviewed studies that reported both self-reported and proxy-reported mean QoL estimates using the same standardized QoL instrument, published in English, and focused on the QoL of people with dementia were included. A meta-analysis was conducted to synthesize the mean differences between self- and proxy-report across different proxy perspectives.

Results
The review included 96 articles from which 635 observations were extracted. Most observations extracted used the proxy-proxy perspective (79%) compared with the proxy-patient perspective (10%); with 11% of the studies not stating the perspective. The QOL-AD was the most commonly used measure, followed by the EQ-5D and DEMQOL. The standardized mean difference (SMD) between the self- and proxy-report was lower for the proxy-patient perspective (SMD: 0.250; 95% CI 0.116; 0.384) compared to the proxy-proxy perspective (SMD: 0.532; 95% CI 0.456; 0.609).

Conclusion
Different proxy perspectives affect the ratings of QoL, whereby adopting a proxy-proxy QoL perspective has a higher inter-rater gap in comparison with the proxy-patient perspective.
Reflective equilibrium in practice and model selection: a methodological proposal from a survey experiment on the theories of distributive justice
Authors: Inoue Akira , Shimizu Kazumi , Udagawa Daisuke , Wakamatsu Yoshiki 
Published: April 2024

AbstractIn political philosophy, reflective equilibrium is a standard method used to systematically reconcile intuitive judgments with theoretical principles. In this paper, we propose that survey experiments and a model selection method—i.e., the Akaike Information Criterion (AIC)-based model selection method—can be viewed together as a methodological means of satisfying the epistemic desiderata implicit in reflective equilibrium. To show this, we conduct a survey experiment on two theories of distributive justice, prioritarianism and sufficientarianism. Our experimental test case and AIC-based model selection method demonstrate that the refined sufficientarian principle, a widely accepted principle of distributive justice, is no more plausible than the prioritarian principle. This tells us that some changes of certain intuitions revolving around sufficientarianism should be examined (separately) based on the findings of the survey experiment and AIC model selection. This shows the potential of our approach—both practically and methodologically—as a novel way of applying reflective equilibrium in political philosophy.
Single-Bubble Cavitation-Induced Pitting on Technical Alloys
Authors: Kühlmann Jonas , Kaiser Sebastian A. 
Published: April 2024

AbstractRepeated single cavitation bubble experiments were performed primarily on 316L stainless steel, and some on nickel–aluminum–bronze (NAB) and pure aluminum. The bubble dynamics were recorded with two high-speed cameras and correlated with surface images, also acquired in situ. These experiments were performed for a range of stand-off distances γ (the ratio of the distance of the solid surface from the bubble to the bubble’s maximum radius) from 0.3 to 2.15. For all stand-off distances, single pits were the only surface change detected at the beginning of damage formation. Later phases of the collapse are not axisymmetric but show regions of “stronger” collapse, and the pits occur on the material underneath those regions. For γ < 0.4, the damage is attributed to the second collapse. For γ > 0.4, the first bubble collapse is most likely responsible for pitting. Shock-wave emission was detected from the collapse regions that were linked to the damage. On 316L, the pitting rate was found to be linearly dependent on the bubble radius, indicating a non-zero lower limit for the bubble radius below which pits do not occur. In terms of stand-off distance, the pitting rate (defined here as average pits per bubble) was non-monotonic, with maxima for bubbles initiated closest to the sample (γ = 0.3) and at γ = 1.4.

Published: April 2024

AbstractThe Amazonian cacao tree or the chocolate tree (Theobroma cacao L.) is cultivated to produce seeds, the valuable raw material for the chocolate industry. However, cacao yield is hampered by diseases and low productivity. Cacao single nucleotide polymorphism (SNP) markers associated with breeding and adaptive traits provide a genetic tool for improving selection and reducing breeding cycles. Here, we genotyped 40 published SNPs associated with disease resistance and 11 SNPs with yield traits in 346 accessions using the MassARRAY® system. These 51 SNPs were identified in different breeding experiments in Costa Rica, Brazil, and Trinidad and Tobago. Four genetic clusters were identified, and two of them were observed in high proportion in managed cacao, characterized by a high proportion of admixed individuals reflecting the man-made hybrids. One cluster overrepresented in managed cacao is associated with the preference to keep superior flavor in cultivated cacao from Criollo ancestry. Introgression of wild material collected in Peru associated with disease resistance to witches’ broom disease (WBD) was also observed. Underutilized genetic resources were observed in managed cacao such as the Guiana cacao, while previous agronomic evaluation has demonstrated its good yield potential. Yield and disease resistance traits (mainly resistance to WBD) show divergence between wild and managed cacao (FST > 0.05) probably reflecting selection during domestication, cultivation, and breeding efforts. Eleven SNPs showed a divergence between wild and managed cacao and can be used to build breeding populations. New collections of wild cacao followed by agronomic evaluations can broaden the genetic base of cultivated cacao, especially for such traits as disease resistance to frosty pod rot (FPR).
Rethinking cluster under coopetition strategy: an integrative literature review and research agenda
Authors: Chim-Miki Adriana Fumi , Fernandes Rosana L. Coelho , Monticelli Jefferson Marlon 
Published: April 2024

AbstractThis study aimed to integrate the dimensions and elements of intra-cluster coopetition, identify the emergence of a complementary theoretical perspective to cluster theory and create an integrative research agenda to support the rethinking cluster approach based on coopetition. It is an integrative Systematic Literature Review that generates insights to move the topic forward. Results showed coopetition as context, process, or outcome. The research focus was grouped into six dimensions of intra-cluster coopetition: Strategic Adjustment, Perceived Benefits, Mediated Coopetition, Social Interaction, Coopetitive Orientation, and Temporality of Coopetition. Four hundred eighty-six elements used by scholars created a second-order coding to represent the variables of coopetition in clusters. From the integrative literature overview, a theoretical framework emerges with four dimensions: Conditional factors, Policies, Market commonality, and Formal supporting structure. These dimensions act as drivers, markets, or intensifiers of the intra-cluster coopetition strategy. At the same time, the dimensions suffer the influence of external, internal, and ecosystem contexts. Our literature review builds theory to advance cluster coopetition research and complement the Porterian perspective. The framework suggests the main elements to manage clusters under the coopetition strategy. These findings rethink cluster theory and deliver the business co-evolution perspective, considering the cluster as a business ecosystem with an open system based on coopetition. Findings offer an inductive-deductive pattern system to further research that represents the evolutionary trend of the topic itself.

Published: April 2024

Abstract

Purpose

The healthcare industry has a growing need for realistic modeling and efficient simulation of surgical scenes. With effective models of deformable surgical scenes, clinicians are able to conduct surgical planning and surgery training on scenarios close to real-world cases. However, a significant challenge in achieving such a goal is the scarcity of high-quality soft tissue models with accurate shapes and textures. To address this gap, we present a data-driven framework that leverages emerging neural radiance field technology to enable high-quality surgical reconstruction and explore its application for surgical simulations.

Method

We first focus on developing a fast NeRF-based surgical scene 3D reconstruction approach that achieves state-of-the-art performance. This method can significantly outperform traditional 3D reconstruction methods, which have failed to capture large deformations and produce fine-grained shapes and textures. We then propose an automated creation pipeline of interactive surgical simulation environments through a closed mesh extraction algorithm.

Results

Our experiments have validated the superior performance and efficiency of our proposed approach in surgical scene 3D reconstruction. We further utilize our reconstructed soft tissues to conduct FEM and MPM simulations, showcasing the practical application of our method in data-driven surgical simulations.

Conclusion

We have proposed a novel NeRF-based reconstruction framework with an emphasis on simulation purposes. Our reconstruction framework facilitates the efficient creation of high-quality surgical soft tissue 3D models. With multiple soft tissue simulations demonstrated, we show that our work has the potential to benefit downstream clinical tasks, such as surgical education.
Institutionen und Parteipolitik machen den Unterschied: Kommunale Abfallvermeidungspolitik in kreisfreien Städten in Nordrhein-Westfalen im Vergleich

Published: April 2024

ZusammenfassungDer Abbau, die Verarbeitung und die Nutzung knapper natürlicher Rohstoffe sind mit negativen Umwelteffekten verbunden. Diese zu reduzieren, erfordert eine konsequente Kreislaufwirtschaft sowie die Reduktion von Stoffströmen. Obwohl Abfallvermeidung rechtlich seit Langem oberste Priorität genießt, lag der Fokus in der Praxis lange Zeit auf der getrennten Sammlung und Verwertung. Für die konsequente Umsetzung von Abfallvermeidungspolitik sind die Kommunen relevant, die für die Entsorgung von Hausmüll verantwortlich sind und Spielraum im Hinblick auf die Abfallvermeidung besitzen. Die Abfallvermeidungspolitiken der Kommunen unterscheiden sich aber hinsichtlich ihres Ambitionsniveaus. Mithilfe einer fuzzy set Qualitative Comparative Analysis (fsQCA) und unter Rückgriff auf die Theorien der vergleichenden Policyforschung untersuchen wir für 22 kreisfreie Städte in Nordrhein-Westfalen (NRW), wie diese Varianz zu erklären ist. Unsere Ergebnisse zeigen, dass für eine nichtambitionierte Abfallvermeidungspolitik eine privatisierte Aufgabenwahrnehmung sowie eine Kombination aus einem niedrigen Sitzanteil der Grünen und hohen Kapazitäten in Müllverbrennungsanlagen (MVA) hinreichend sind. Der Anteil der Grünen im Rat sowie institutionelle Faktoren spielen aber auch in der Erklärung ambitionierter Abfallvermeidungspolitiken eine Rolle. Damit schließen wir an Diskussionen um die Bedeutung der Parteiendifferenz in der Umweltpolitik und auf der kommunalen Ebene sowie zu den Effekten von Privatisierung an. In Anbetracht großer Modernisierungsbedarfe bei MVA sind unsere Ergebnisse außerdem für die aktuelle kreislaufwirtschaftliche Debatte relevant.
Community-based sustainability initiatives: the quality of relationships matter?
Authors: Carmen E. , Fazey I. , Friend R. M. 
Published: April 2024

AbstractThe quality of relationships between different actors involved in community-based sustainability initiatives is central to their success. This study examines the role of the qualities of social relationships within 22 different community-based sustainability initiatives each framed round different types of sustainability challenges, from flooding and climate change to community development and youth engagement. Research involved 37 semi structured interviews, combined with visual techniques, to explore the qualities of different relationship from the perspective of actors actively engaged in developing and progressing initiatives with different communities across Scotland. A typology of relationship qualities (tense, pragmatic and supportive qualities) is presented and applied to examine the ways in which relationships shape the benefits that participants identify for these community-based initiatives. The findings show supportive relationship qualities, involving a sense of respect, integrity, honesty and opportunities to test out new ideas, are particularly important in sustainability initiatives, providing a diverse range of benefits. Relationship qualities can also shift over time, either relatively suddenly or incrementally. Some groups of initiative actors worked strategically with relationships, underpinning their relationship-based strategies with relationships with different actors dominated by supportive qualities to actively harness the benefits these types of relationships provide and strengthen the sense of community and shared interest surrounding initiatives. A focus on relationship qualities can therefore provide a more dynamic picture of how community-based initiatives unfold and adapt to increasingly complex challenges. Such an approach places human agency centre-stage, recognising the fundamental importance of shaping social relationships within community-based initiatives.
