Assessing students’ perceptions of school climate in primary schools
Authors: Aldridge J. M. , Blackstock M. J. 
Published: March 2024

AbstractResearch at the secondary school level provides compelling evidence to suggest that a positive school climate is related to improved health, wellbeing, and cognitive outcomes for students. In response to these findings, school systems around the world are mandating the collection of school climate data in schools. However, reviews of the literature indicate that there are relatively few instruments that provide evidence to support translation and criterion validity and assess the school climate from the perspectives of primary school students; and all of them were considered unsuitable or problematic for our purposes. To overcome this gap in the literature, this article describes the development and validation of a school climate survey designed to assess primary school students’ perceptions of school climate. Evidence to support translation validity is provided through data collected at various stages of the development process. Further, data collected from a sample of 1193 primary school students (years 3 to 6) were analysed to provide evidence to support convergent, discriminant concurrent, and predictive validity. The survey and evidence of its psychometric properties are significant for researchers, schools, and education systems seeking to assess primary school students’ perception of the school climate.
Some new perspectives on the Kruskal–Szekeres extension with applications to photon surfaces
Authors: Cederbaum Carla , Wolff Markus 
Published: March 2024

AbstractIt is a well-known fact that the Schwarzschild spacetime admits a maximal spacetime extension in null coordinates which extends the exterior Schwarzschild region past the Killing horizon, called the Kruskal–Szekeres extension. This method of extending the Schwarzschild spacetime was later generalized by Brill–Hayward to a class of spacetimes of “profileh” across non-degenerate Killing horizons. Circumventing analytical subtleties in their approach, we reconfirm this fact by reformulating the problem as an ODE, and showing that the ODE admits a solution if and only if the naturally arising Killing horizon is non-degenerate. Notably, this approach lends itself to discussing regularity across the horizon for non-smooth metrics. We will discuss applications to the study of photon surfaces, extending results by Cederbaum–Galloway and Cederbaum–Jahns–Vičánek-Martínez beyond the Killing horizon. In particular, our analysis asserts that photon surfaces approaching the Killing horizon must necessarily cross it.

After regularization, the index is written in terms of elliptic gamma functions, reminiscent of four-dimensional holomorphic blocks, and crucially depends on the R-charge.
The Hemodialysis Distress Thermometer for Caregivers (HD-DT-C): development and testing of the psychometric properties of a new tool for screening psychological distress among family caregivers of adults on hemodialysis
Authors: Sousa Helena , Ribeiro Oscar , Figueiredo Daniela 
Published: March 2024

Abstract
Purpose
To develop and test the measurement properties of the HD-DT-C, a new tool designed to facilitate the screening of psychological distress and its sources in family caregivers of adults on hemodialysis.

Methods
The present investigation was carried out in three phases: Phase 1 focused on the process of developing and exploring the content validity and clinical utility of the HD-DT-C using a mixed-methods approach and feedback panels; Phase 2, where the psychometric properties of this new tool were tested in a cross-sectional study (n = 106 caregivers); and Phase 3, where the European Portuguese version of the HD-DT-C was translated and culturally adapted into American English using a forward–backward translation procedure, followed by an expert panel review.

Results
Findings suggested that the HD-DT-C was perceived by feedback panels as practical, appropriate, and useful for increasing dialysis provider/family caregiver communication in nephrology centers. The European Portuguese version of the HD-DT-C showed good test–retest reliability (ICC = 0.991 for the barometer and κ ≥ 0.80 in 77% of the checklist items), high diagnostic accuracy (AUC = 0.956), and strong convergent validity (all r ≥ 0.50) with reference measures that assess quality of life, caregiver burden, and symptoms of anxiety and depression. Cutoff scores with good clinical utility (CUI +  ≥ 0.70) were recommended for screening distress in research (≥ 6) and clinical practice (≥ 5).

Conclusion
The HD-DT-C is a brief, reliable, valid, and acceptable measure for identifying self-reported psychological distress and its sources among people caring for a family member or friend on hemodialysis. Future research is needed to explore the measurement properties of the American English version of this new tool.
Limitarianism, Upper Limits, and Minimal Thresholds
Authors: Timmer Dick 
Published: March 2024

AbstractLimitarianism holds that there is an upper limit to how many resources, such as wealth and income, people can permissibly have. In this article, I examine the conceptual structure of limitarianism. I focus on the upper limit and the idea that resources above the limit are ‘excess resources’. I distinguish two possible limitarian views about such resources: (i) that excess resources have zero moral value for the holder; and (ii) that excess resources do have moral value for the holder but that their claim to such resources is outweighed by other normative concerns. Moreover, I argue that, depending on the values limitarianism seeks to promote, limitarians should care about the number of people with excess resources or the total amount of excess resources (or both), that they can adopt redistributive measures and/or predistributive measures, and that some versions of limitarianism should take into account the distribution of risk among those above the riches line.
Beyond the Passive Absorption of Information: Engaging Students in the Critical Reading of Scientific Articles
Authors: Archila Pablo Antonio , Ortiz Brigithe Tatiana , Truscott de Mejía Anne-Marie 
Published: March 2024

AbstractThere is a consensus within the science education community that primary scientific literature is a legitimate and desirable educational resource. Moreover, critical reading of scientific articles is widely recognized as a key aspect of scientific literacy. However, university science courses rarely provide students with explicit opportunities to cultivate their critical reading skills. Much of the reason for this is that instructors tend to hold a passive learning view of reading in which students are expected to absorb information from scientific articles. The purpose of this study was to provide research evidence that an active learning scenario (ALS) combining (1) argumentation, (2) peer critique (also referred to as peer assessment), and (3) the Task-Oriented Reading Instruction framework (Ritchey & List, College Teaching, 70(3), 280–295, 2022) could be a concrete and realistic possibility for engaging students in the critical reading of scientific papers. The data analyzed in this study were the written critiques of scientific research articles and written peer feedback produced by sixty-one university students (38 females and 23 males, 19–25 years old). The results indicate that the ALS effectively offered students explicit opportunities to become more active and more critical readers of scientific articles, producing arguments, anticipating counterarguments, and constructing rebuttals. Implications related to critical reading instruction in science education and supporting students’ development of critical reading skills are discussed.
Intersex in the USA’s Best-Selling Undergraduate Psychology Textbooks: Uneven Critique in an Ongoing Scientific and Ethical Crisis
Authors: Hegarty Peter , Vaughan Sam 
Published: March 2024

AbstractThe field of intersex studies is advancing and requires scholars to update their knowledge and representation of people with intersex variations. To examine how psychology students are taught about people with intersex variations, we reviewed best-selling USA psychology textbooks in introductory psychology (n = 8), psychology of women and gender (n = 5), human sexuality (n = 4), and biological psychology (n = 3). All textbooks indexed intersex or cognate terms, with alternative terms (e.g., disorders of sex development) indexed less frequently. Intersex variations were described as emerging during the stages of sex development, and as challenging binary categories for sex. Several specific variations were commonly described as syndromes with little reference to psychological research or lived experiences. Women and girls with congenital adrenal hyperplasia (CAH) were most clearly framed as “natural experiments” about how nature and nurture intersect. Diverse sex development involving 46 XY genotypes tended to be described as difference from norms for male endosex development. However, two textbooks included lengthy narratives of people’s lived experiences as intersex, and photographs of intersex-identified individuals were common. Photo images of the South African athlete Caster Semenya depicted more of her body than did the photo images of other intersex-identified individuals. The textbooks generally included critical reflection on the assumptions of a gender binary, and on the attribution of ambiguity to others’ bodies, genetic determinism, the medical gaze, and the sex testing of athletes. We consider how information in these textbooks can shape the representation of intersex among psychology students, and how it may be used to develop more humanizing representations of intersex across all psychology textbooks.
Does Atypical Employment Come in Couples? Evidence from European Countries
Authors: Westhoff Leonie 
Published: March 2024

AbstractThe literature on atypical employment has largely focused on the individual level. This paper provides a novel account of the dynamics of atypical employment, specifically part-time and temporary employment, within couples. Analyzing a sample of 29 European countries using 2016 EU-SILC data, it investigates the association between partner and own atypical employment. The results show that temporary employment does come in couples, in that partner temporary employment is associated with a higher likelihood of own temporary employment. A significant portion of this result is driven by individuals with partners in temporary employment themselves exhibiting characteristics predisposing them to temporary employment. These results are largely consistent across Europe. Accumulation of part-time employment is also observed, albeit at a smaller scale. However, it occurs at the two extremes of the income distribution only, among very low-earning and very high-earning couples. In contrast, in the middle of the income distribution, there is no association between partner and own part-time employment, which is more consistent with classic household specialization patterns. An association between partner and own part-time employment is only found in a minority of European countries, most systematically in Northern and Western Europe, but also in some Southern and Eastern European countries.
Students’ thoughts about dropping out: Sociodemographic factors and the role of academic help-seeking

Published: March 2024

AbstractDropout is a problematic issue in education due to its high prevalence and impact on students and society. In fact, it can limit students’ future options, and it involves a substantial cost for public budgets in most countries. This is not an easy problem to solve, since student dropout is a complex decisional process involving such factors as personal and contextual characteristics, educational variables, and psychosocial aspects. Very few studies have examined whether sociodemographic and psycho-educational variables affect educational dropout at different academic levels. For this reason, the present study aims to provide a better understanding of the role of several variables (age, academic results, gender, sexual orientation, academic help-seeking, academic self-efficacy, and planning as a strategy to cope with academic stress) in educational dropout thoughts in a sample of 759 students resident in Spain (age: M = 22.91, 74.0% women). Regression analyses showed that dropout thoughts were significantly predicted by academic results, planning, sexual orientation, academic self-efficacy, and academic help-seeking. Agreements and discrepancies with previous research are discussed. The results of the current study can be used by educators, policy makers and institutions to develop programmes to reduce student dropout by enhancing self-regulated learning strategies.
Application of a Bio-waste Einkorn (Triticum monococcum L.) Husks Adsorbent for Removal of Metanil Yellow and Methylene Blue from Aqueous Media with Equilibrium, Kinetic, and Thermodynamic Studies
Authors: Kocabiyik Baris , Bayrak Yuksel 
Published: March 2024

AbstractIn this study, the activated carbon (TmAC) with a high surface area and appropriate pore distribution was produced from einkorn (Triticum monococcum L.) husks by using ZnCl2 with chemical activation method. The efficiency of the obtained activated carbon on the adsorption of anionic (metanil yellow) and cationic (methylene blue) dyestuffs from aqueous solutions was investigated in more detail. In addition, the surface characterization of activated carbon was performed using thermogravimetric analysis-differential thermal analysis (TGA-DTA), elemental analysis, scanning electron microscopy (SEM) images, Brunauer–Emmett–Teller (BET) specific surface areas, N2 adsorption–desorption isotherms, pore volumes, pore size distributions, and Fourier-transform infrared spectroscopy-attenuated total reflection (FTIR-ATR) spectra. The highest surface area of activated carbon was measured as 1321 m2 g−1 at the carbonization temperature of 500 °C by using impregnation ratio (w/w = 2.0). Batch method was used in adsorption experiments. The parameters affecting the adsorption studies such as adsorbent concentration, initial dye concentration, adsorption time, temperature, and pH were investigated. The adsorption mechanisms of metanil yellow (MY) and methylene blue (MB) on activated carbon were explained by using isotherms (Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich), kinetic models (pseudo-first-order and pseudo-second-order), and the thermodynamic parameters (Gibbs free energy, enthalpy, and entropy).

Published: March 2024

AbstractBiopesticides, having as active ingredients viruses, bacteria, or fungi, are developed to substitute or reduce the use of chemical plant protection products in different agrosystems. Though the application of mixtures containing several products is a common practice, interactions between microbial biopesticides and related effects on bees as non-target organisms have not been studied yet. In the current study, we exposed winter bees to five different microbial-based products and their combinations at the maximum recommended application rate to assess their responses. Laboratory oral exposure tests (acute/chronic) to single or binary products were conducted. Survival and food consumption of the tested bees were evaluated over the experimental duration. Our results show that some product combinations have potential additive or synergistic effects on bees, whereas others did not affect the bee’s survival compared to the control. Exposure of tested bees to the most critical combination of products containing Bacillus thuringiensis aizawai ABTS-1857 and B. amyloliquefaciens QST 713 strongly resulted in a median lifespan of 4.5 days compared to 8.0 and 8.5 days after exposure to the solo products, respectively. The exposure to inactivated microorganisms by autoclaving them did not differ from their respective uncontaminated negative controls, indicating effects on bee mortality might originate in the treatment with the different microorganisms or their metabolites. Further investigations should be conducted under field conditions to prove the magnitude of observed effects on bee colonies and other bee species.

AbstractThe progression of multisystem neurodegenerative diseases such as ataxia significantly impacts speech and communication, necessitating adaptive clinical care strategies. With the deterioration of speech, Alternative and Augmentative Communication (AAC) can play an ever increasing role in daily life for individuals with ataxia. This review describes the spectrum of AAC resources available, ranging from unaided gestures and sign language to high-tech solutions like speech-generating devices (SGDs) and eye-tracking technology. Despite the availability of various AAC tools, their efficacy is often compromised by the physical limitations inherent in ataxia, including upper limb ataxia and visual disturbances. Traditional speech-to-text algorithms and eye gaze technology face challenges in accuracy and efficiency due to the atypical speech and movement patterns associated with the disease.In addressing these challenges, maintaining existing speech abilities through rehabilitation is prioritized, complemented by advances in digital therapeutics to provide home-based treatments. Simultaneously, projects incorporating AI driven solutions aim to enhance the intelligibility of dysarthric speech through improved speech-to-text accuracy.This review discusses the complex needs assessment for AAC in ataxia, emphasizing the dynamic nature of the disease and the importance of regular reassessment to tailor communication strategies to the changing abilities of the individual. It also highlights the necessity of multidisciplinary involvement for effective AAC assessment and intervention. The future of AAC looks promising with developments in brain-computer interfaces and the potential of voice banking, although their application in ataxia requires further exploration.
Investigation of river water pollution using Muskingum method and particle swarm optimization (PSO) algorithm
Authors: Norouzi Hadi , Bazargan Jalal 
Published: March 2024

AbstractRiver water pollution is one of the most important environmental issues. Advection–dispersion equations are used to study the temporal changes in pollutant concentration along the study river reach. The use of advection–dispersion equations in investigating how the concentration of pollution is transformed requires a lot of data including river cross-section characteristics, dispersion coefficient, and upstream and downstream boundary conditions, etc. therefore, the corresponding calculations are very costly, difficult and time-consuming. In the present study, instead of using the mentioned equations, the linear Muskingum method (used in previous studies for flood routing) and the particle swarm optimization (PSO) algorithm was used for the first time to calculate the temporal changes in pollution concentration at different stream locations. The presented solution in the presented study is very accurate and only requires the temporal changes in concentration in the upstream and downstream of the study river reach and for this reason, it is very low-cost and easy to use and requires less time to collect data and perform calculations. In the proposed method, the parameters (X, K, ∆t) of the linear Muskingum method were optimized using the PSO algorithm, and by dividing the temporal changes in the input concentration into three areas of the beginning (the input concentration is greater than the output concentration), the peak (the maximum input and output concentrations) and the end (the output concentration is greater than the input concentration) areas, the accuracy of the calculations increased. The mentioned method was studied for different lengths (first case of x = 50 m (up) and x = 75 m (down), second case of x = 50 m (up) and x = 100 m (down), third case of x = 75 m (up) and x = 100 m (down)) and the mean relative error (MRE) of the total, peak area and the relative error of the maximum concentration using constant parameters for the first case were calculated as 7.08, 1.02, and 2.34 percent, for the second case as 7.41, 11.06 and 6.69 percent, and for the third case as 6.75, 3.59 and 5.42 percent, respectively. If three parameters of (X, K, ∆t) are used, the mentioned values improved by 31.3, 63.7 and 65.5 percent, respectively compared to the case of using constant parameters.
Interactions between chloride-based salts (CaCl2 and MgCl2), ionic liquids, pH, and titanium oxide nanoparticles under low and high salinity conditions, and synthetic resinous crude oil: dorud oilfield
Authors: Pazhoohan Mehrdad , Hezave Ali Zeinolabedini 
Published: March 2024

AbstractUnfortunately, oil reservoirs are complex considering the fluids (e.g., crude oil composition) and rock properties making it hard to propose a simple enhanced oil recovery (EOR) method for higher oil production. Besides, most of the investigations had focused on crude oil which is a complex mixture of thousands of components making it hard to extract any reliable conclusions with respect to the crude oil type. So, the current study is focused on the application of ionic liquids from different families of pyridinium and imidazolium, titanium oxide nanoparticles, and salts (MgCl2 and CaCl2) in the presence of resinous synthetic oil for the first time. The obtained results using the central composite design (CCD) approach revealed the positive effect of resin fraction on the IFT reduction by 27% considering the initial value (34.9%). Using the CCD approach revealed that using pH = 7, MgCl2 concentration = 21,000 ppm, CaCl2 concentration = 21,000 ppm, resin fraction of 9wt%t and 500 ppm of [C12mim][Cl] concentration reduces the IFT to minimum value of 0.62 mN/m while the minimum IFT value for optimum conditions of solution includes [C12py][Cl] led to minimum IFT value of 2.2 mN/m. But, the contact angle measurements revealed better synergy between [C12py][Cl] and TiO2-NPs (0–200 ppm) for better wettability alteration toward water-wet condition (27.3°) than [C12mim][Cl] (33.2°). Moreover, the IFT measurements revealed that the presence of TiO2-NPs is effective in reducing the IFT of the optimum formulations to 0.55 and 0.84 mN/m for [C12mim][Cl], and [C12py][Cl], respectively. According to the results, it seems that the obtained optimum formulations for [C12mim][Cl], and [C12py][Cl] are applicable for EOR purposes as new hybrid solutions.
