Published: July 2023

AbstractIn recent years, interest in adhesive bonding has grown as it can be considered an efficient solution in terms of strength‐to‐mass ratio when applied to lightweight structures or an interesting solution to complement conventional technologies. The study of bonded adhered joints is carried out using a technique based on the macro‐element method (ME), the ME shape functions are modeled using Taylor expansion power and Fourier expansion series. The purpose of this work is to compare the stiffness matrix obtained first from the entire Taylor series and then with the entire Fourier series. The method has been developed so far for 1D‐bar and 1D‐beam kinematics frameworks.
Pluralizing environmental values for urban planning: How to uncover the diversity of imaginaries about socio‐natures from Vitoria‐Gasteiz (Basque Country, Spain)

Published: July 2023

Abstract

Cities have pushed forward re‐naturing initiatives in local planning agendas. Discourses and rationales for such interventions tend to follow instrumental framings often narrowed down to the economic, health and ecological benefits of nature's contributions to people (NCP). Yet, diverse urban residents often connect to other socio‐nature framings that are associated with a plurality of values held for nature, including relational, intrinsic, and instrumental values.

Focusing mostly on urban NCP, we used Q‐methodology to explore the perspectives and expressions of urban residents' diversity of values for urban greenery and broader human‐nature relationships. We explore the role of both instrumental and relational values, as well as certain potential disvalues of urban NCP. In light of the recent IPBES values assessment (IPBES, 2022) we follow a call for empirical studies and methodologies to explore, elicit and visibilize plural values about nature.

We base our study in the Basque city of Vitoria‐Gasteiz, Spain (2012 European Green Capital) where we identify four distinct perspectives, all of which relate to a diversity of values about urban nature. Urban residents mostly perceive positive values for NCP as directly connected to their wellbeing. Yet, NCP that impact social bonds within their social community, expressed for instance through community‐related values, are perceived differently across the four perspectives.

We conclude that planners and decision‐makers should pay scrutiny to include the four, partly differing, perspectives about the plural values of (urban) NCP in policymaking processes to assure just and inclusive outcomes. Here, intersectional and participatory approaches are needed beyond dominating framings of NCPs and related values, especially those that can take into account the needs and preferences of marginalized social groups. Special emphasis should be put on integrating relational values as nourishing such values through planning can play an important role in creating place‐rooted connections with local urban landscapes and the community.

Recycled silica as a renewable and sustainable alternative to carbon black in natural rubber foams
Authors: Rostami‐Tapeh‐Esmaeil Ehsan , Kazemi Hossein , Ahmad Hibal , Morin Michel , Rodrigue Denis 
Published: July 2023

AbstractSustainable natural rubber foams were prepared by replacing petroleum‐based carbon black (CB) with recycled silica (SiO2) nanoparticles. The total nanofiller concentration was fixed at 40 phr, while the CB/silica ratio was changed from 40/0 to 0/40. The results showed that increasing the silica content increased the curing characteristics, such as delta torque (ΔM) by 54%, scorch time (ts) by 50% and optimum curing time (t90) by 65%. But foams based on a hybrid system (20/20) produced a more homogeneous structure improving the cell nucleation step and leading to the smallest cell size (18 μm) and highest cell density (8.8 × 103 cells mm−3) due to reduced filler−filler interactions and better particle dispersion. This improved cellular morphology generated superior mechanical and thermal insulation performance, including the highest compression modulus (2.7 MPa), compressive strength (1.9 MPa) and recoverability (96.6%) combined with the lowest thermal conductivity (0.114 W m−1 K−1) at a density of 0.652 g cm−3. Nevertheless, the foam with 40 phr silica showed higher compressive modulus (26%) and compression strength (15%) compared to the reference sample having 40 phr CB, mainly due to its higher crosslink density. As a final comparison, the recycled silica, being a suitable and sustainable alternative to petroleum‐based CB, showed superior mechanical and thermal insulation properties compared to a commercial grade of silica for natural rubber foams. © 2023 The Authors.

Examining the factors influencing students' knowledge‐sharing behavior in the social media‐based learning community
Authors: Karaoglan Yilmaz Fatma Gizem , Yilmaz Ramazan 
Published: July 2023

AbstractVirtual learning communities can be formed through social media platforms, enabling the implementation of various learning activities. One of the essential components of virtual learning communities created on social media is the knowledge‐sharing behaviors (KSB) of students. Studies show that some students actively participate in the knowledge‐sharing processes, while some students do not actively participate in this process the observed phenomenon could potentially be attributed to the psycho‐social condition of the students. The main goal of this research was to establish the factors related to the KSB of the students in the virtual learning community created in the social media environment. The research investigated the structural associations among KSB, need for social approval (NfSA), happiness, self‐control and self‐management (SC‐SM), and dispositional hope (DH) structures. A total of 176 university students, engaged in the virtual learning community formed on social media, were included in the research. The research was implemented within the scope of Computing II course. Students used the virtual learning community created for the course during one academic semester and shared knowledge. In the study, relationships between structures were discovered by path analysis. Research results showed that the NfSA and DH were significantly related to KSB. According to the results, happiness and SC–SM did not significantly relate to KSB. It can be said that supporting students' social approval needs and increasing hope levels can be beneficial to improve students' KSB in virtual learning communities to be created in social media environments. According to another result of the study, it was observed that as the SC–SM levels of the students increased, their happiness and DH levels also increased. In line with the results obtained from the results, what can be done to improve the KSB of students in virtual learning communities was discussed, and various suggestions were made for researchers and practitioners.

Published: July 2023

AbstractA growing number of patients with metabolic disorders are receiving statin and antidiabetic therapies as comedications. A signal of increased risk of myotoxicity due to potential interactions between antidiabetics and statins has been detected in previous studies. To investigate the effects of metformin on myopathy risks when added to preexisting statin therapy in dyslipidemia patients, we performed a retrospective cohort study using the Korean national health insurance data in statin‐treated dyslipidemia patients with or without concomitant metformin use. We compared the risk of myopathy in statin + metformin users against statin‐only users. Hazard ratios (HRs) and 95% confidence intervals (CIs) have been calculated following propensity score (PS) matching between study groups and subsequent stratification per patient factors. We included 4092 and 8161 patients in PS‐matched statin + metformin and statin‐only groups, respectively. The risk of myopathy decreased when metformin was used together with statins (adjusted HR 0.84; 95% CI 0.71–0.99). In subgroup analyses per individual statin agent and in stratified risk analyses, no specific statin agents or patient factors were associated with statistically significant myopathy risk. This study found that a comedication with metformin was associated with decreased myopathy risk in statin‐treated dyslipidemia patients compared to statin‐only users. Our findings suggest that metformin may provide protective effects on potential muscle toxicities induced by statin therapy.
Determining the minimum duration of treatment in tuberculosis: An order restricted non‐inferiority trial design
Authors: Serra Alessandra , Mozgunov Pavel , Davies Geraint , Jaki Thomas 
Published: July 2023

AbstractTuberculosis (TB) is one of the biggest killers among infectious diseases worldwide. Together with the identification of drugs that can provide benefits to patients, the challenge in TB is also the optimisation of the duration of these treatments. While conventional duration of treatment in TB is 6 months, there is evidence that shorter durations might be as effective but could be associated with fewer side effects and may be associated with better adherence. Based on a recent proposal of an adaptive order‐restricted superiority design that employs the ordering assumptions within various duration of the same drug, we propose a non‐inferiority (typically used in TB trials) adaptive design that effectively uses the order assumption. Together with the general construction of the hypothesis testing and expression for type I and type II errors, we focus on how the novel design was proposed for a TB trial concept. We consider a number of practical aspects such as choice of the design parameters, randomisation ratios, and timings of the interim analyses, and how these were discussed with the clinical team.
Modeling immunogenecity data to establish screening bioassays cut point

Published: July 2023

AbstractThe response of immunogenecity anti‐drug antibody (ADA) generally includes biological and analytical variability. The nature of biological and analytical variations may lead to a variety of symmetric and asymmetric ADA data. As a result, current statistical methods may yield unreliable results because these methods assume special types of symmetric or asymmetric ADA data. In this paper, we survey and compare parametric models that are useful for analyzing a variety of asymmetric data that have rarely been used to calculate assay cut points. These models include symmetric distributions as limiting case; therefore, they are useful in the analysis of a variety of symmetric data. We also investigate two nonparametric approaches that have received little attention in screening cut point calculations. A simulation study was conducted to compare the performance of the methods. We evaluate the methods using four published different types of data, and make recommendations concerning the use of the methods.
Identifying overvalued equity
Authors: Beneish Messod D. , Nichols David Craig 
Published: July 2023

AbstractWe develop a profile of overvalued equity, and show that firms meeting this profile experience abnormal stock returns net of transaction costs of −22% to −25% over the 12 months following portfolio formation. We show our model is distinct from predictors proposed in prior work, and our results robust to alternative measurements of expected returns. We also show that overvaluation is not confined to small firms and that institutions do not trade as if they identify overvalued equity. The profitable predictability we document suggests a pricing anomaly relating to the 2.5% of the firms in the population that our model identifies as substantially overvalued. Although we believe markets are generally efficient within the bounds of transaction costs, our evidence suggests that violations of minimally rational use of publicly available information do occur. To the extent that anomalies disappear or attenuate once documented in the literature (Doukas et al., 2002 [European Financial Management, 2002, 8, 229]; Schwert, 2003 [Handbook of the Economics of Finance, 2003, 1, 939]), our results are of interest to financial economists and investors.
The effects of modeling‐based pedagogy on conceptual understanding, scientific reasoning skills, and attitudes towards science of English learners
Authors: Malone Kathy L. 
Published: July 2023

AbstractThe use of scientific modeling has been shown to be highly effective in the learning of science content in multiple disciplines for non‐English Learners (EL). However, the benefits of using this pedagogy with ELs have not been heavily explored. This article discusses the use of modeling‐based evolution and population ecology pedagogical units in a sheltered biology high school class for ELs. A sheltered EL class is one where only ELs are enrolled and they learn both language and science concurrently. This article specifies the at the scaffolding used to adjust the pedagogy for this unique set of students. The effectiveness of this method was assessed using a convergent mixed method case study design. Data was collected using assessments in content, scientific reasoning and attitudes towards science (i.e., self‐efficacy, fascination, and valuation of science) as well as teacher interviews, and classroom observations. The cases were an EL modeling‐based sheltered biology class, and two non‐EL inquiry‐based biology classes, all at the upper secondary level. The EL modeling cohort achieved posttest comparison content scores that were not significantly different from the non‐EL cohort and significantly higher posttest scientific reasoning scores. The effect sizes in both of these cases were much larger for the EL cohort. The affective assessments demonstrated intriguing results with the EL cohort having a greater fascination with science than the non‐EL cohort but a decline in self‐efficacy. Both cohorts valued science to the same extent. This methodology holds promise in helping to decrease the science gap between ELs and non‐ELs taught with inquiry‐based pedagogies.
Triggering the Channel‐Sulfur Sites in 1T′‐ReS2 Cocatalyst toward Splendid Photocatalytic Hydrogen Generation

Published: July 2023

AbstractElectron density manipulation of active sites in cocatalysts is of great essential to realize the optimal hydrogen adsorption/desorption behavior for constructing high‐efficient H2‐evolution photocatalyst. Herein, a strategy about weakening metal–metal bond strength to directionally optimize the electron density of channel‐sulfur(S) sites in 1T′ Re1−xMoxS2 cocatalyst is clarified to improve their hydrogen adsorption strength (S─H bond) for rapid H2‐production reaction. In this case, the ultrathin Re1−xMoxS2 nanosheet is in situ anchored on the TiO2 surface to form Re1−xMoxS2/TiO2 photocatalyst by a facial molten salt method. Remarkably, numerous visual H2 bubbles are constantly generated on the optimal Re0.92Mo0.08S2/TiO2 sample with a 10.56 mmol g−1 h−1 rate (apparent quantum efficiency is about 50.6%), which is 2.6 times higher than that of traditional ReS2/TiO2 sample. Density functional theory and in situ/ex situ X‐ray photoelectron spectroscopy results collectively demonstrate that the weakened Re─Re bond strength via Mo introduction can induce the formation of unique electron‐deficient channel‐S sites with suitable electron density, which yield thermoneutral S─H bonds to realize superior interfacial H2‐generation performance. This work provides fundamental guidance on purposely optimizing the electronic state of active sites by manipulating the intrinsic bonding structure, which opens an avenue for designing efficacious photocatalytic materials.
Institutional pathways for transforming groundwater planning and management: Reflections from Pakistan and Sri Lanka

Published: July 2023

AbstractThe growing issues with groundwater quality and quantity worldwide are particularly impacting regions of South Asia, where groundwater use plays a crucial role in human well‐being. As the severity of the situation becomes clearer, there are increasing calls for transformation in water management. In this paper, we consider institutional influences on transforming groundwater management by reflecting on our recent collaborative research in Pakistan and a scoping study in Sri Lanka. In Pakistan, we have shown that it is possible for previously “siloed” stakeholders to develop shared understandings of the groundwater situation and build useful and enduring practice networks. Such shared understandings can support collaborative planning, but must be informed by effective monitoring and modeling, and an institutional willingness to think beyond traditional formal regulatory tools. Regional and local scale planning could encourage interactive processes for broader thinking. Given the similarity in the human‐groundwater situation between parts of Pakistan and Northern Sri Lanka, we undertook a small study to see if similar collaborative research would be valuable there. Our brief visit confirmed commonalities in the situation. By reflecting on our experience in Pakistan and Sri Lanka, we make a case for encouraging and embracing collaborative research as part of transforming water resources management. Our approach emphasizes the important contributions of both water managers and users and encourages ways of integrating paradigms, knowledge, norms, and practices. Establishing genuine co‐inquiry among groundwater managers and users requires a deeper appreciation of the constraining and enabling roles established institutions can play and thus ultimately a transformation in institutional arrangements.

Published: July 2023

AbstractIn the present study, the free vibration of functionally graded graphene platelet‐reinforced (FG‐GPLs) and functionally graded carbon nanotube‐reinforced (FG‐CNTs) hybrid laminated nanocomposite truncated conical shells and panels are analyzed. Multi‐layers truncated conical shell and panel of pure FG‐CNTs, pure FG‐GPLs and hybrid CNTs‐GPLs reinforcement were evaluated. In light of its high accuracy in the calculation of thin and thick shells, a third‐order shear deformation theory is adopted. The governing equations and boundary conditions is derived using Hamilton's principle and is solved numerically using the systematic differential quadrature method (DQM) which uses Kronecker delta function. The effective mechanical properties of the CNT‐reinforced nanocomposite layers are estimated using the rule of mixtures, whereas those of the GPL‐reinforced nanocomposite layers is calculated using the Halpin‐Tsai micromechanical model. Convergence and accuracy evaluation of the presented study are confirmed and a number of parameters, including the CNTS volume fraction, GPLs mass fraction, distribution patterns (i.e., Uniform distribution (UD), Functionally graded O‐distribution (FG‐O), Functionally graded X‐distribution (FG‐X), Functionally graded V‐distribution (FG‐V) and FG‐A), different boundary conditions and the vertex angle of the cone, are investigated. The results obtained in this article for the combination of two different materials, GPLs and CNTs, showed that in controlling the natural frequency of the system, without changing the percentage of fiber and only by changing the arrangement, very wonderful results can be achieved.

Published: July 2023

AbstractStroke is a medical emergency that is associated with substantial mortality and functional disability in adults. The most popular class of antidepressants, selective serotonin reuptake inhibitors SSRIs, have recently been shown in studies to have positive effects on post-stroke motor and cognitive function. Thus, we hypothesized that dapoxetine (DAP), a short-acting SSRI, would be effective against cerebral ischemia/reperfusion injury. Adult male Wister rats (200–250 g) were subjected to a sham operation or bilateral common carotid artery occlusion (BCCAO) for 30 min followed by 24 h of reperfusion to induce global cerebral ischemia/reperfusion (I/R) injury. Rats were treated with vehicle or DAP (30 or 60 mg/kg, i.p.) 1 h before BCCAO. The neurobehavioral performance of rats was assessed. The infarct volume, histopathological changes, oxidative stress parameters, and apoptotic and inflammatory mediators were determined in the brain tissues of euthanized rats. Our results confirmed that DAP significantly ameliorated cerebral I/R-induced neurobehavioral deficits, reduced cerebral infarct volume, and histopathological damage. Moreover, DAP pretreatment reduced lipid peroxidation, caspase-3, and inflammatory mediators (TNF-α and iNOS) compared to I/R-injured rats. Thus, DAP pretreatment potentially improves neurological function, and cerebral damage in cerebral ischemic rats may be partly related to the reduction in the inflammatory response, preservation of oxidative balance, and suppression of cell apoptosis in brain tissues.
