AbstractThe seroprevalence of Toxoplasma gondii in domestic cats, dogs and rabbits was evaluated. Samples from cats and dogs were collected from five veterinary practices from various parts of Poland - Poznan (wielkopolskie voivodeship), Przemysl (podkarpackie voivodeship), Kluczbork (opolskie voivodeship), Lublin (lubelskie voivodeship) and Deblin (lubelskie voivodeship). Moreover, the samples from rabbits were collected in Poznan. In total, serum samples from 193 cats, 204 dogs and 71 rabbits were randomly selected and tested for specific antibodies against T. gondii using a commercial ELISA test. Pathogen seroprevalence among cats and dogs was calculated at a 95% confidence interval (CI) for each sex and age category (up to 12 months, 1–3 years, 4–7 years and over 8 years) and compared with a chi-squared test. The highest seroprevalence of T. gondii was noted in cats − 49.74% (96/193; 95% CI: 42.76–56.73). In dogs, it reached 28.92% (59/204; 95% CI: 23.13–35.49). Only 1 rabbit (3-year-old male) was seropositive, and the seroprevalence in rabbits was 1.41% (1/71; 95% CI: 0.25–7.56). A statistically significant correlation between seropositivity and age (p < 0.05) was observed in cats and dogs. No statistically significant difference in seroprevalence concerning gender or location was found in cats and dogs. Our findings indicate that cat and dog serum samples had a high frequency of anti-T. gondii antibodies, while rabbit serum samples had low frequency and that these species are exposed to T. gondii in Poland and develop humoral response due to infection.
Schulprogramme zur Förderung der psychischen Gesundheit. Die psychische Gesundheitskompetenz von Lehrpersonen als wichtiger Umsetzungsfaktor

Published: January 2023

Zusammenfassung
Hintergrund
Weltweit sind bis zu einem Fünftel der Kinder und Jugendlichen von psychischen Störungen betroffen. Auffälligkeiten, die bereits im Schulalter auftreten, sind insbesondere für die Betroffenen, aber auch die Lehrpersonen belastend. Schulische Präventionsprogramme zur psychischen Gesundheit haben das Potenzial, die Belastungen beidseitig zu reduzieren. Die psychische Gesundheitskompetenz von Lehrpersonen, die nicht nur das Wissen und das Verständnis, sondern auch die Handlungen untersucht, gilt dabei als wichtiger Umsetzungsfaktor. Die Studienlage ist mager.

Ziele
Die Studie untersucht die psychische Gesundheitskompetenz von Lehrpersonen im Kontext von Belastungssituation der Schülerinnen und Schüler sowie das Vorhandensein entsprechender Schulprogramme.

Methoden
Im Schuljahr 2019/2020 wurden alle Lehrpersonen in einer Deutschschweizer Stadt zu einem Online-Survey eingeladen (n = 1514; Rücklauf: 38 %). Die Daten wurden quantitativ mittels bivariater und multivariater Methoden ausgewertet. Eine offene Frage zum Verständnis psychischer Störungen wurde qualitativ mittels einer Inhaltsanalyse ausgewertet.

Resultate und Diskussion
Die Befragten betreuten oder unterrichteten im letzten Jahr durchschnittlich 4,7 psychisch belastete Schülerinnen und Schülern. Die Anzahl Betroffener unterschied sich nach Schulstufe und Schulfunktion. Die Lehrpersonen schätzten ihre Fähigkeit, Informationen zum Thema zu finden und zu verstehen als (sehr) gut ein, es fiel ihnen jedoch schwerer, zu beurteilen, ob die gefundenen Informationen korrekt sind. Die Handlungskompetenz der Lehrkräfte war partiell gering, beispielsweise beim Wissen über Störungsbilder und stellt ein Hindernis in der Umsetzung von Schulprogrammen dar. Lehrkräfte relativierten auffälliges Verhalten, was die Triage für weitere Abklärungen erschwert. Den Schulen wird zum einen empfohlen in die Eigeninitiative der Lehrpersonen zu investieren, zum anderen sollte die Steigerung der psychischen Gesundheitskompetenz nicht nur Aufgabe der Lehrpersonen sein, sondern durch eine entsprechende Schulkultur und gesellschaftlich gefördert werden.

Abstract
Ni-based superalloys are indispensable for applications in demanding environments, such as the heavily stressed rotating discs in the hot sections of modern gas turbines or jet engines. In this paper, the microstructure evolution during hot deformation to mimic the forging process was investigated in the polycrystalline VDM® Alloy 780 via
in situ X-ray diffraction at temperatures of 950, 1000, and 1050 °C. For the tested temperatures, the hot forming led to subgrain formation, the built-up of a texture by rotation of the matrix grains into preferred orientations, and dynamic recrystallization. The influence of the deformation was analyzed depending on the direction of the lattice plane normals to the load direction, for the first five γ-reflections in the diffraction pattern. During uniaxial compressive deformation intensity, maxima develop in the loading direction solely for the γ-(220) reflections, while intensity minima develop for the other reflections which correspond to the formation of a <110> fiber texture. In the transverse direction, all γ-reflections except the (220) have an increased intensity at the maximum specimen strain of 20 pct. Directly after the hot forming, three different cooling rates of 10, 100, and 1000 °C/min and their influence on the microstructure were investigated. The fast and medium cooling rates lead to low recrystallized fractions and a largely preserved deformation texture, whereas the low cooling rate leads to a high recrystallized fraction and a slight remaining texture. Additionally, the diffraction data are complemented by electron microscopy measurements.

Abstract
In order to launder large amounts of money, (drug) criminals can seek help from financial facilitators. According to the FATF, these facilitators are operating increasingly business-like and even participate in professional money laundering networks. This study examines the extent to which financial facilitators in the Netherlands exhibit business-like characteristics and the extent to which they organize themselves in money laundering networks. We further examine the relationship between business-like behavior and individual money launderers’ position in the social network. Using police intelligence data, we were able to analyze the contacts of 198 financial facilitators who were active in the Netherlands in the period 2016–2020, all having worked for drug criminals. Based on social network analysis, this research shows that financial facilitators in the Netherlands can be linked in extensive money laundering networks. Based on the facilitators’ area of expertise, roughly two main types of professional money laundering networks can be discerned. Some subnetworks operate in the real estate sector, while others primarily engage in underground banking. Furthermore, the application of regression models to predict business-like behavior using individual network measures shows that facilitators with more central positions in the network and those who collaborate with financial facilitators from varying expertise groups tend to behave more business-like than other financial facilitators.
Men’s Gender Norms and Gender-Hierarchy-Legitimizing Ideologies: The Effect of Priming Traditional Masculinity Versus a Feminization of Men’s Norms

AbstractContemporary evidence suggests that masculinity is changing, adopting perceived feminine traits in the process. Implications of this new masculine norm on gender relations remain unclear. Our research aims to better understand the influence of changing masculine norms on men’s endorsement of gender-hierarchy-legitimizing ideologies. Based on Precarious Manhood Theory and Social Role Theory, we conducted two quasi-experimental studies (N = 412) in which we first assessed heterosexual men's motivation to protect traditional masculinity. Then, we informed them that men’s gender norms are becoming more feminine (feminization norm condition) or are remaining masculine in a traditional sense (traditional norm condition). In the third (baseline-control) condition, participants received no information about men’s gender norms. Finally, we assessed the extent to which participants endorsed gender-hierarchy-legitimizing ideologies, namely sexism (Study 1) and masculinist beliefs (Study 2). Results showed that men who were less motivated to protect traditional masculinity were less likely to endorse gender-hierarchy-legitimizing ideologies when exposed to the feminization and control conditions compared to the traditional norm condition. The implications of these findings for gender equality and gender relations are discussed.
Repeatability of a bending stiffness test for snowboarding wrist protectors

Published: January 2023

AbstractSnowboarding wrist protectors are typically designed to limit impact forces and prevent wrist hyperextension. The standard for snowboarding wrist protectors (ISO 20320:2020) includes a test for measuring their bending stiffness, when fitted to a wrist surrogate. This test serves as a simple means of assessing the ability of wrist protectors to prevent wrist hyperextension. Wrist protector bending stiffness measurements have been shown to be influenced by surrogate design, protector strapping condition, and surrogate surface compliance. Currently, there is a lack of knowledge on the repeatability of bending stiffness measurements, as previous studies have conducted tests during one session. This study investigated the repeatability of a bending stiffness test, by testing two snowboarding wrist protectors (short and long) on two wrist surrogates (compliant and stiff), under three protector strapping conditions (loose, moderate, tight), across three repeated test sessions. Test session had a significant effect (p < 0.05) on torque values, with a large effect size ($$\eta_{{\text{p}}}^{2}$$

> 0.14), indicating the test had limited repeatability between test sessions. Despite this limited repeatability, torque values increased with both wrist angle and strap tightness, as reported before, indicating consistent trends in results. The outer surface compliance of the surrogate did not significantly affect the protector’s sensitivity to test session nor strapping condition.

AbstractThe Task Force on Rotational Atherectomy of the Japanese Association of Cardiovascular Intervention and Therapeutics (CVIT) proposed the expert consensus document to summarize the techniques and evidences regarding rotational atherectomy (RA) in 2020. Because the revascularization strategy to severely calcified lesions is the hottest topic in contemporary percutaneous coronary intervention (PCI), many evidences related to RA have been published since 2020. Latest advancements have been incorporated in this updated expert consensus document.
Solving fractional time-delay diffusion equation with variable-order derivative based on shifted Legendre–Laguerre operational matrices
Authors: Farhood Adnan Khalaf , Mohammed Osama H. , Taha Bushra A. 
Published: January 2023

AbstractThis article adopts a novel technique to numerical solution for fractional time-delay diffusion equation with variable-order derivative (VFDDEs). As a matter of fact, the variable-order fractional derivative (VFD) that has been used is in the Caputo sense. The first step of this technique is constructive on the construction of the solution using the shifted Legendre–Laguerre polynomials with unknown coefficients. The second step involves using a combination of the collocation method and the operational matrices (OMs) of the shifted Legendre–Laguerre polynomials, as well as the Newton–Cotes nodal points, to find the unknown coefficients. The final step focuses on solving the resulting algebraic equations by employing Newton’s iterative method. To illustrate and demonstrate the technique’s efficacy and applicability, two examples have been provided.
Effects of pore size on the lubrication properties of porous polyimide retainer material
Authors: Chen Wenbin , Wang Wenzhong , Zhu Pengzhe , Ge Xiangyu 
Published: January 2023

AbstractAn oil-impregnated porous polyimide (PI) retainer is used in space rolling bearings to improve the lubrication performance, which depends on the release of lubricant from the pores, and therefore is closely related to the pore size. To study the effect of pore size, in this work, PI materials with different pore sizes were prepared by preheating the retainer tube billet during the limit pressing process, and then the friction tests were conducted with the ball-on-ring mode. The results show that the applied load deforms the pores, allowing the lubricant to be squeezed out from the pore; the centrifugal effect induced by rotation also makes the lubricant migrate out of the pore. Therefore, for the same pore sizes, the friction coefficients decrease with the increasing loads and rotation speeds. In addition, it was found that there exists an optimal pore size for the best lubrication properties of porous PI material. Furthermore, the optimal pore size should be larger for lubricants with high viscosity. The microscopic mechanism for lubricant outflow from pores is clarified by molecular dynamic simulations. The insights gained in this study can guide the preparation of oil-impregnated porous retainers under different working conditions.
Complex Mathematics Education: An Integrated and Inquiry-Based Mathematics Teaching Method
Authors: Kiss Anna 
Published: January 2023

AbstractLittle is available in mathematics education research about what the teacher can anticipate from the students when applying inquiry-based learning (IBL). Even less is known about how to recognize and exploit on the spot when a mathematical domain, other than the one in focus, is activated in the students’ minds. Yet, in tests, in everyday life, and the labour market, it is common to face problems that require interrelated mathematical thinking. Although one of the unique advantages of complex mathematics education (CME) is the coherence between different domains and CME has been practiced for over half a century in Hungary, the Hungarian line of IBL has only recently joined the international methodological mainstream. In this paper, I summarize a segment of IBL correspondent to CME and integrated mathematics education, and I illustrate the possible divergence of solutions during implementation with an example that emerged about a probability game in a fifth-grade class.
Effects of biochar carried microbial agent on compost quality, greenhouse gas emission and bacterial community during sheep manure composting

Published: January 2023

AbstractAlthough composting is a very effective way to dispose agricultural wastes, its development is greatly limited by the low compost quality and greenhouse gas emissions. At present, there is a lack of effective means to solve these two problems simultaneously. Here, the effects of three additives of compound microbial agent, biochar and biochar carried microbial agent on the composting performance, nitrogen transformation, greenhouse gas and ammonia emissions, and bacterial communities were investigated in sheep manure composting during 28 days. Results showed that biochar carried microbial agent prolonged the thermophilic stage and promoted compost maturity. At the same time, it was confirmed by the increase of the decomposition of organic nitrogen and the transformation of NH4+-N to NO3−-N. Besides, adding biochar carried microbial agent decreased CH4, NH3 and N2O emissions by 65.23%, 42.05% and 68.64%, respectively. The gas emissions were mainly correlated to Chloroflexi, Myxococcota, Acidobacteriota, Firmicutes, and Gemmatimonadota. Redundancy analysis showed that EC and TKN were closely related to bacterial community. Therefore, biochar carried microbial agent is recommended as an effective additive to enhance compost quality and reduce gas emissions during sheep manure composting.

Role of biochar toward carbon neutrality
Authors: Wang Liuwei , Deng Jiayu , Yang Xiaodong , Hou Renjie , Hou Deyi 
Published: January 2023

AbstractCarbon neutrality by the mid-twenty-first century is a grand challenge requiring technological innovations. Biochar, a traditional soil amendment which has been used for fertility improvement and contaminant remediation, has revealed new vitality in this context. In this review we highlight the huge potential of biochar application in different fields to mitigate as high as 2.56 × 109 t CO2e total greenhouse gas (GHG) emissions per year, accounting for 5.0% of the global GHG emissions. Soil applications of biochar as either a controlled-release fertilizer or an immobilization agent offer improved soil health while simultaneously suppressing the emissions of CH4and N2O. Non-soil applications of biochar also contribute to carbon neutrality in unique ways. Firstly, biochar application as a ruminant feed decreases CH4emissions via physical sorption and enhanced activities of methanotrophs. Secondly, biochar can be used as a green catalyst for biorefinery. Besides, biochar as an additive to Portland cement and low impact development (LID) infrastructure lowers the carbon footprint and builds resilience to climate change. Furthermore, biochar can be used as novel batteries and supercapacitors for energy storage purposes. Finally, the high CO2adsorption capacity makes it possible for biochar being used as a sorbent for carbon capture, utilization, and storage (CCUS). We advocate that future research should further explore the effectiveness of biochar systems for climate change mitigation in large scale applications, and assess the economic and social viability of local biochar systems to combat climate change.Graphical Abstract
Nature immersions: teaching reading through a real-world curriculum
Authors: Bates Katherine 
Published: January 2023

AbstractDebates about teaching reading have long been a part of educational vernacular, frequently reduced to polarised views about phonics. This attention can unnecessarily divert from the cumulative skills required for learning to read and comprehensive research, which indicates the positive influence of systematic phonics instruction on students’ reading outcomes. Australian education has recently moved beyond these reading wars to include explicit phonics instruction in a reformed national English Curriculum. This provides an opportune time to engage preservice teachers entering the workforce with strategies that explicitly teach these skills while nurturing young people’s ecological consciousness through positive nature connections. With this focus in mind, a participatory action research project involving preservice teachers was undertaken, from which an Eco-Conceptual Framework ensued. The project put immersive activities in place, promoting transdisciplinary ways to develop learners’ connections with nature using images collected from participants’ real world when learning to read. Results indicate that action research energised preservice teachers’ perceived knowledge, self-efficacy about teaching early reading utilising place and skills in designing visual resources. It brings attention to the critical influence of preservice teachers’ dispositions and preferred natural spaces on what images are collected and offered when designing early reading activities utilising the natural world.
On New Notions of Algorithmic Dimension, Immunity, and Medvedev Degree
Authors: Webb David J. 
Published: January 2023

We prove various results connected together by the common thread of computability theory.First, we investigate a new notion of algorithmic dimension, the inescapable dimension, which lies between the effective Hausdorff and packing dimensions. We also study its generalizations, obtaining an embedding of the Turing degrees into notions of dimension.We then investigate a new notion of computability theoretic immunity that arose in the course of the previous study, that of a set of natural numbers with no co-enumerable subsets. We demonstrate how this notion of
$\Pi ^0_1$
-immunity is connected to other immunity notions, and construct
$\Pi ^0_1$
-immune reals throughout the high/low and Ershov hierarchies. We also study those degrees that cannot compute or cannot co-enumerate a
$\Pi ^0_1$
-immune set.Finally, we discuss a recently discovered truth-table reduction for transforming a Kolmogorov–Loveland random input into a Martin-Löf random output by exploiting the fact that at least one half of such a KL-random is itself ML-random. We show that there is no better algorithm relying on this fact, in the sense that there is no positive, linear, or bounded truth-table reduction which does this. We also generalize these results to the problem of outputting randomness from infinitely many inputs, only some of which are random.Abstract prepared by David J.

The Design and Welfare Implications of Mandatory Pension Plans
Authors: Larsen Linda S. , Munk Claus 
Published: January 2023

AbstractIn a rich, calibrated life-cycle model, we show that well-designed mandatory pension plans significantly improve the welfare of individuals procrastinating on savings, and even improve most rational individuals’ welfare through a return tax advantage and fair annuitization. For a group of heterogeneous savers, in terms of preferences and sophistication, the best plan has contributions of 10% of income from age 30, a glidepath investment strategy, payouts following a variable lifelong annuity, and options to choose a different investment strategy and to modify the annuitization feature. This plan generates an average welfare gain of $175,000 per individual.
