Authors: Blanchard Sheresa Boone , Yeh Chia Jung , Busio Dionne Sills , Mann Lydia , Bruhn Alexis 
Published: August 2024

AbstractEarly childhood educators (birth through second grade) have faced a wide range of challenges while providing education and care for the youngest group of children. Their positions often range from child-care settings to grade school, with different configurations for benefits, class size, and salary. During the first year of the COVID-19 pandemic, 192 early educators shared their perceived stress levels and personal and employment context including relationship status, caregiving responsibilities, education level, work setting, and age group. While there were noted differences across the group, educators working in school-aged settings and those who were caregivers (outside of work) reported higher levels of stress. Interview results from a subset of survey respondents showed concerns about online learning and the well-being of their students, while also underscoring personal growth through the challenges.

Published: August 2024

AbstractThe concept of growth mindset—an individual’s beliefs that basic characteristics such as intelligence are malleable—has gained immense popularity in research, the media, and educational practice. Even though it is assumed that teachers need a growth mindset and that both teachers and their students benefit when teachers adopt a growth mindset, systematic syntheses of the potential advantages of a growth mindset in teachers are lacking. Therefore, in this article, we present the first meta-analysis on teachers’ growth mindset and its relationships with multiple outcomes (50 studies, 81 effect sizes; N = 19,555). Multilevel analyses showed a small effect across outcomes. Statistically significant small-to-typical positive associations between teachers’ growth mindset and their motivation in terms of self-efficacy and mastery goals were observed in subgroup analyses. No statistically significant relationships were found with teachers’ performance-approach goals, teachers’ performance-avoidance goals, teachers’ performance on achievement tests, or student achievement. Teachers’ growth mindset was related to instructional practices in terms of mastery goal structures but unrelated to performance goal structures. Moderator analyses indicated that the dimensionality of the mindset measure (recoded from a fixed mindset to a growth mindset measure vs. assessed as a growth mindset), item referent and content of the mindset measure, publication status (published vs. unpublished), world region, educational level, and study quality influenced the strengths of some of the relationships. Overall, our findings extend knowledge about teachers’ mindset and add to the evidence base on teacher characteristics and their links to relevant outcomes.
Asymptotic solution of electromagnetic heating of skin tissue with lateral heat conduction

Published: August 2024

AbstractWe study the temperature evolution in the three-dimensional skin tissue exposed to an electromagnetic beam of millimeter wavelength. The skin absorption coefficient of the beam frequency determines how deep the electromagnetic energy penetrates into the skin tissue, which gives a sub-millimeter penetration depth for a 94 GHz wave. In contrast, in the lateral directions perpendicular to the depth, the beam size is usually much larger than the penetration depth. Based on this separation of length scales, we establish an asymptotic formulation in which each term has separable dependences on the depth coordinate and on the lateral coordinates. We solve it analytically to obtain a two-term asymptotic solution of the temperature distribution in the three-dimensional skin tissue. This closed-form analytical solution provides a practical and accurate way of predicting the temperature. When the beam size is moderately larger than the penetration depth (a ratio of 20), the effect of lateral heat conduction is well captured in the asymptotic solution with maximum error less than 0.0017 in the normalized temperature of magnitude well above 1.

AbstractThis short communication presents the findings of the work conducted by the human behaviour in fire permanent working group of the International Association for Fire Safety Science. Its aim is to identify determinants of research gaps in the field of human behaviour in fire. Two workshops were conducted in 2023 in which research gaps were identified and discussed by twenty experts. The workshops led experts through a series of questions to determine the reasons (or determinants) for these gaps in human behaviour in building fires and wildfires. Through the questions, the primary identified determinants were (1) researchers’ literacy in the variety of methods adopted in the field, (2) difficulties associated with recruitment of study participants, (3) multi-disciplinary barriers across different research sub-domains, and (4) issues in obtaining funding for addressing fundamental human behaviour in fire research questions. Two key issues emerged from an open discussion during the workshops, namely the difficulties in attracting and training new people in the field (given the limited educational offers around the world on the topic) and the need for more regular opportunities for the community to meet.
Meanders, hyperelliptic pillowcase covers, and the Johnson filtration
Authors: Jeffreys Luke 
Published: August 2024

AbstractWe provide minimal constructions of meanders with particular combinatorics. Using these meanders, we give minimal constructions of hyperelliptic pillowcase covers with a single horizontal cylinder and simultaneously a single vertical cylinder so that one or both of the core curves are separating curves on the underlying surface. In the case where both of the core curves are separating, we use these surfaces in a construction of Aougab–Taylor in order to prove that for any hyperelliptic connected component of the moduli space of quadratic differentials with no poles there exist ratio-optimising pseudo-Anosovs lying arbitrarily deep in the Johnson filtration and stabilising the Teichmüller disk of a quadratic differential lying in this connected component.
Empathy and Autism: Establishing the Structure and Different Manifestations of Empathy in Autistic Individuals Using the Perth Empathy Scale

Published: August 2024

Abstract
Purpose
There is a common mischaracterisation that autistic individuals have reduced or absent empathy. Measurement issues may have influenced existing findings on the relationships between autism and empathy, and the structure of the empathy construct in autism remains unclear.

Methods
The present study sought to address these gaps by examining the structure and psychometric properties of the Perth Empathy Scale (PES) in autistic individuals (N = 239) compared to non-autistic individuals (N = 690).

Results
Our moderated non-linear factor analysis revealed that the multidimensional empathy construct manifested similarly in autistic and non-autistic individuals, with the PES displaying good validity and reliability. Moreover, the results revealed that autistic individuals reported reduced cognitive empathy and reduced affective empathy for positive and negative emotions. However, there was greater heterogeneity of empathic tendencies in the autistic sample, indicating that these mean differences may not be generalisable for all autistic individuals.

Conclusion
The present study highlights that the PES is suitable for assessing empathy across autistic and non-autistic individuals. This work with the PES also provides greater nuance to our understanding of empathy and autism, and based on these findings, we propose the empathy heterogeneity hypothesis of autism as a new way of describing empathy in autism.

Published: August 2024

Abstract
Background
Despite no scientific evidence linking vaccines to Autism Spectrum Disorder (ASD), vaccine hesitancy persists among parents of children with ASD. This study aims to compare vaccine hesitancy and behaviors among parents of children with ASD, other Neurodevelopmental Disorders (NDD), and without NDD, and to examine the relationship between stress coping mechanisms and vaccine hesitancy, including comparing coping mechanisms between diagnostic groups as well as their association with hesitancy.

Methods
In this cross-sectional study, one parent of each child with ASD, non-ASD NDD, or without NDD was included. Data were collected using a researcher-created form, the Vaccine Hesitancy Scale in Turkish, and the Coping Style Scale Brief Form. Vaccine hesitancy, parents’ COVID-19 vaccination status, and vaccination status of children’s younger siblings were analyzed through univariate and multivariate analyses, with a focus on correlations between vaccine hesitancy and coping styles.

Results
The study included one parent from each of 299 children. Parents of children with ASD showed an adjusted odds ratio of 2.66 (95% CI 1.35–5.06) for high vaccine hesitancy, 2.57 (95% CI 1.17–5.65) for not receiving the COVID-19 vaccine, and 1.40 (95% CI 0.45–4.40) for younger siblings not receiving routine vaccines. A weak but significant correlation was observed between vaccine hesitancy and the use of restraint coping style among these parents (r = 0.280; p = 0.010).

Conclusions
The study underscores the importance of targeted educational efforts and personalized communication to address vaccine hesitancy among parents of children with ASD. Enhancing vaccination coverage in this community requires further research to develop interventions tailored to their specific needs.
Influence of alloying elements on microstructure, mechanical properties and corrosion behaviour of hypoeutectic Sn-6.5wt%Zn-0.5 wt%X (X = Ag, Al, Cu) lead-free solders

AbstractLead-free solders are promising candidates for the replacement of Sn–Pb solders due to their environmental friendly, good thermal properties and wettability which render them suitable for this application. In this study, a set of lead-free solders Sn-6.5 wt. and Sn-6.5 wt% Zn-0.5 wt% X (X = Ag, Al, Cu) were studied by metallography, mechanical and electrochemical techniques. The results show that the addition of the alloying elements Ag, Al and Cu modifies the amount of the eutectic phase and promotes the formation of intermetallic compounds (IMCs). The corrosion resistance of the samples also modified, showing that the formation of IMCs can have detrimental effects with higher current densities in saline media, as determined for the Ag and Al alloyed solders. The corrosion resistance is higher for the unalloyed and the Sn-6.5 wt%Zn-0.5 wt% Cu alloy. However, the addition of Cu not only stabilizes the corrosion products thus increasing the protective properties of the alloy, but also modifies the mechanical behaviour of the lead-free solders and so enhancing the UTS values and ductility. Furthermore, the surface morphology is influenced by the alloying elements showing a smooth surface (Sn-Zn, Cu) or a highly corroded appearance with round aggregates (Ag and Al). These new lead-free solders have a lower melting point with higher ductility than the commercial SAC 305. Therefore, these alternatives have high potential in applications in mechanical engineering.

Published: August 2024

AbstractDue to their higher thermal and chemical stability than other high-temperature materials, chromium-silicon-base (Cr-Si-base) alloys are promising materials for future gas turbines and other high-temperature applications operating under harsh conditions. To enable near-net-shape casting of Cr-Si-base alloys, a compatibility of the alloy melt with the ceramic crucibles and molds is necessary. Additionally, a metal-ceramic contact exists at the interface between thermal barrier coating (TBC) and alloy, where metallic may melts play a role in the case of coating failure and overheating. In this study, molten Cr92Si8 (in at. %) alloy is brought into contact with powders of ceramics commonly used for casting molds or crucibles (e.g. ZrSiO4, Al2O3, 3YSZ), to investigate liquid metal corrosion, interdiffusion, and stabilities. Additionally, the high entropy oxide (Sm0.2Gd0.2Dy0.2Er0.2Yb0.2)2Zr2O7 (HEO), a potential future TBC material, is investigated. Before melting using an electric arc furnace, the powders of the investigated ceramics were mixed with pulverized Cr92Si8 and pressed into alloy-ceramic pairs, to maximize the contact area between molten metal and ceramic. For microstructural investigations and phase analysis, the materials were assessed using scanning electron microscopy (SEM) equipped with energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). The widely used mold material ZrSiO4 and the coating BN were found to decompose, while reaction products of SiO2 and CoAl2O4 with the melt were detected. Al2O3, 3YSZ, and the HEO did not show decomposition or corrosion by the melt. Al2O3, 3YSZ, and the HEO are therefore considered as promising crucible, mold, and TBC materials for Cr-Si-base alloys.

Published: August 2024

Abstract

Background
Aortic valve stenosis (AS) is the most prevalent valvular heart disease and is associated with a significant increase in mortality. AS has been shown to be linked with numerous coagulation system abnormalities, including increased fibrin deposition on the stenotic aortic valves. Transcatheter aortic valve implantation (TAVI) is the primary treatment method for patients at high surgical risk.

Objectives
The aim of the study was to assess the impact of treating severe AS with TAVI on thrombin generation and clot lysis time (CLT).

Methods
We studied 135 symptomatic AS patients recommended for TAVI by the local Heart Team. All measurements were performed before and 5-7 days after TAVI. Alongside clinical assessment and echocardiographic analysis, we assessed clot lysis time (CLT) and thrombin generation parameters, including lag time, peak thrombin generation, time to peak thrombin generation (ttPeak), and endogenous thrombin potential (ETP).

Results
70 patients were included in the final analysis. After TAVI, there was a significant 9% reduction in CLT despite a 12% increase in fibrinogen concentration. We observed significant increase in lag time and ttPeak (20% and 12%, respectively), and 13% decrease in peak thrombin concentration compared to pre-procedural levels. Multivariable linear regression analysis demonstrated that baseline CLT and C-reactive protein (CRP) levels were independent predictors of significant reduction in mean aortic gradient, defined as TAVI procedure success.

Conclusions
CLT and peak thrombin concentration decreased, while Lag time and ttPeak increased significantly after TAVI. Multivariable linear regression analysis demonstrated CLT and CRP levels as independent predictors of achieving a reduction in mean aortic gradient, defining TAVI procedure success.

Published: August 2024

AbstractIdentifying environmental variables that affect the distribution of pest and/or nuisance species promotes effective management strategies by improving urban planning and the targeted application of direct interventions like population control. Australian white ibis Threskiornis moluccus are considered a nuisance species throughout Australia, having increased significantly in abundance in coastal urban landscapes following declines in their native inland habitats over the past three decades. Few management interventions thus far have successfully reduced conflicts between ibis and humans, necessitating a better understanding of conditions driving ibis distribution and abundance. We surveyed 26 ibis colonies throughout the Moreton Bay region in central eastern Australia and quantified the effects of a range of spatial (e.g. connectivity with waste management facilities, urban land and wetlands) and habitat (e.g. nesting tree species, density and size) variables on ibis and nest abundance. Ibis and their nests were most abundant at sites within 10 km of waste management facilities, and < 60 m from residential or industrial estates. Ibis were also more abundant at sites with tree canopy height < 10 m and lower tree species richness. Nests were most abundant on water bound islands with tree density > 0.5 trees/m2. Urbanisation had contrasting effects, with nest numbers increasing with higher connectivity (i.e. closer proximity) to urban land, while ibis numbers decreased (relative to waste management facilities). Multifaceted approaches are required for controlling ibis populations, including restricting access to anthropogenic food resources, managing the condition of remnant habitats, and considering population control at sites with high connectivity to foraging grounds.

AbstractAortic stenosis has become the most prevalent valvular disease with increasing life expectancy and the ageing of the population, representing a significant clinical burden for health care providers. Its treatment has been revolutionized by transcatheter aortic valve replacement (TAVR) as a safe and minimally invasive option for elderly patients. Left ventricular (LV) functional measurement is of particular importance before TAVR, however, increased afterload significantly influences the conventional echocardiographic parameters. Non-invasive myocardial work examines myocardial deformation in the context of instantaneous LV pressure, thus, it might be a more reliable measure of LV function. Accordingly, we aimed to study non-invasive myocardial work and its relationship with functional outcome following TAVR.We enrolled 90 TAVR candidates (80 [75–84] years; 44% female). Using echocardiography, we quantified ejection fraction (EF), global longitudinal strain (GLS), global myocardial work index (GWI) and global constructive work (GCW) before and 12 months after the procedure. Serum NT-proBNP levels were also measured. EF did not change (52.6 ± 13.1 vs. 54.2 ± 10.5%; p = 0.199), while GLS increased (-13.5 ± 4.6 vs. -15.2 ± 3.8%; p < 0.001). GWI decreased (1913 ± 799 vs. 1654 ± 613 mmHg%; p < 0.001) and so did GCW (2365 ± 851 vs. 2177 ± 652 mmHg%; p = 0.018). History of atrial fibrillation (AF) (β = 0.349) and preprocedural GCW (β = -0.238) were independent predictors of postprocedural NT-proBNP (p < 0.001).GLS, GWI and GCW changed after TAVR while there was no alteration in EF. The preprocedural GCW and history of AF were independent predictors of postprocedural NT-proBNP. Accordingly, myocardial work indices may help patient selection and the prediction of the functional outcome in this population.

AbstractThis study was aimed to determine the effects of various fruit juices used as impregnation solutions on the physicochemical, textural and sensory properties of dried chicken meat cubes. The pH, color parameters, total phenolic, antioxidant activity, water holding capacity, textural (TPA) and sensorial properties of the cubes were tested. Impregnation solutions used in the treatment groups were prepared with pomegranate, black grape and black mulberry juices, and salt solution (control). Impregnation was performed in two replicates and two samples were analyzed per replicate. The cubes were immersed in the solutions and the 10 min vacuum (250 mbar absolute pressure) − 10 min atmospheric pressure cycle was repeated at 4 °C for 2 h. pH values decreased (P < 0.01) by impregnation with various anthocyanin-rich fruit juices. Total phenolic and antioxidant activity were the highest (P < 0.01) in samples impregnated with pomegranate juice and were 720.71 mg GAE/kg and 840.22 mg TE/kg, respectively. The use of anthocyanin-rich fruit juices as impregnation solution decreased a* and b* values of samples (P < 0.01; P < 0.05, respectively). The TPA results indicated that impregnation with pomegranate, black grape and black mulberry juices induced lower (P < 0.01) hardness and higher (P < 0.05) adhesiveness values compared to the control. Consequently, the impregnation with anthocyanin-rich fruit juices such as pomegranate, black grape and black mulberry has the potential to improve the quality properties of dried chicken cubes.
