AbstractMining activity is one of the main sources to pollute soil, water and plants. An analysis of soil and plant samples around the Atrevida mining area in Catalonia (NE Spain) was preformed to determine potentially harmful elements (PHEs). Soil and plant samples were taken at eight locations around the mining area. The topsoil (0–15 cm) samples were analysed for physico-chemical properties by standard methods, by ICP-MS for Cd, Co, Cr, Cu, Fe, Ni, Pb and Zn, and were microwave-digested. Plant, root and shoot samples were digested separately, and heavy metals were analysed by AAS. Translocation factor (TF), biological concentration factor (BCF) and biological accumulation factor (BAF) were determined to assess the tolerance strategies developed by native species and to evaluate their potential for phytoremediation purposes. Soil pH was generally acid (5.48–6.72), with high soil organic matter (SOM) content and a sandy loamy or loamy texture. According to the agricultural soil values in southern Europe, our PHEs concentrations exceeded the toxicity thresholds. The highest root content of the most studied PHEs appeared in Thymus vulgaris L. and Festuca ovina L., while Biscutella laevigata L. accumulated more PHEs in shoots. The TF values were > 1 in B. laevigata L., but BAF obtained < 1, except Pb. B. laevigata L., and can be considered potentially useful for phytoremediation for having the capacity to restrict the accumulation of large PHEs amounts in roots and Pb translocation to shoots.
What is the problem and how can we solve it? School authorities’ perceptions of the shortage of teachers in Sweden
Authors: Boström Lena 
Published: May 2023

AbstractThe lack of fully trained teachers is a national challenge in Sweden despite numerous attempts by authorities to approach the issue from a long-term perspective. The proportion of fully trained teachers needs to increase by just over 50% by 2035, and the imbalance will continue for many years to come. Many actors such as the media and politicians have participated in the debate, but not those who are significantly forced to handle, control, and lead in resolving the current situation and who have an overview of the problems at a structural level, namely, the school authorities (school authority in the school system according to the Education Act (Skollagen 2010: 800) can be a municipality, county council, state, or individual who is responsible for the activities in the school. In this text, the most responsible head of a municipality in the educational department has responded to the survey). This study covers 55 school authorities’ views on national tendencies and possibilities of solving this problem using an enactment policy theory. The empirical data are based on a web survey and analyzed through thematic content analysis. The result shows deep concerns about the accelerated problem, the challenges of finding fully trained teachers, and negative attitudes toward the profession. Possible solutions are higher salaries, flexible solutions to becoming teachers, higher status, and better working environments. The school authorities’ perceptions of possible solutions are to some extent consistent with ongoing political initiatives. Neither do they emphasize an overall picture of the working conditions for teachers, nor the far-reaching consequences of all political reforms. In summary, their actions are interpreted as quite re-active, nonlinear, and ad hoc solutions and less proactive perceptions and actions. This can possibly be explained by the fact that the state sets limits on economic initiatives.
Which side are you on? Spider web positioning affects prey capture more than body colour

AbstractColour has been hypothesized to play a crucial role in prey capture for sit-and-wait predators that rely on visual cues to deceive their prey. Prey capture success has been directly linked to colouration in spiders; however, evidence so far focuses mostly on dorsal colouration, excluding ventral patterns that are visible to prey and may be relevant for prey attraction. Here, we explored whether the dorsal and ventral colouration of a colour polymorphic spider is associated with light environment and prey capture success. We quantified the number of prey captured across three dorsal (black, white, and yellow) and two ventral (black and a mosaic yellow/orange pattern) morphs of Gasteracantha cancriformis, considering light intensity on dorsal and ventral sides. We found that spiders capture more prey in low light environments, and that individuals often expose their dorsal colouration towards low light levels. We did not find significant differences in prey capture rate between morphs dorsally or ventrally. These results indicate that how and where spiders position their web can be more important for prey capture than colouration. Alternative hypotheses such as aposematism, camouflage and thermoregulation deserve more attention in future studies that aim to understand the role of colouration in spiders and the factors causing spider colour polymorphisms.

AbstractThe importance of supporting parent-child interactions has been noted in the context of prodromal autism, but little consideration has been given to the possible contributing role of parental characteristics, such as psychological distress. This cross-sectional study tested models in which parent-child interaction variables mediated relations between parent characteristics and child autistic behaviour in a sample of families whose infant demonstrated early signs of autism (N = 103). The findings suggest that associations between parent characteristics (psychological distress; aloofness) and child autistic behaviours may be mediated by the child’s inattentiveness or negative affect during interactions. These findings have important implications in developing and implementing interventions in infancy which target the synchrony of parent-child interaction with the goal to support children’s social communication development.

AbstractResearch has shown that psychosocial and behavioral factors are associated with engagement in a range of deviant behaviors across offline settings. To date, however, very little research has explored the impact of these factors in online contexts. This article addresses this gap by examining the psychosocial and behavioral factors associated with common types of adolescent cyberdeviance. This is accomplished through an empirical study of 327 adolescents enrolled in a high school located in a large Australian city. The study assesses various aspects of psychosocial and behavioral functioning using the Strengths and Difficulties Questionnaire (total difficulties, internalizing problems, externalizing problems, prosocial behavior), as well as numerous types of cyberdeviance relevant to young people, including cyberfraud, cyberhate, cyberviolence, sexting, digital piracy, hacking, and cyberbullying. A series of multivariate logistic regression analyses were conducted to demonstrate the association between psychosocial and behavioral difficulties and various types of cyberdeviance, independent of gender, school grade, socioeconomic status, and engagement in offline delinquency. Results indicate that total difficulties, internalizing problems, and externalizing problems were significantly associated with greater likelihood of engagement in most types of cyberdeviance examined in this study, whereas prosocial behavior was associated with a lower likelihood of engagement in digital piracy only. A discussion of the findings highlights the importance of understanding these factors in a digital context, as well as demonstrating the need to account for them when designing targeted interventions.

AbstractVasospasm during reconstructive microsurgery is a common, uncertain, and devastating phenomena concerning flap survival. Topical vasodilators as antispasmodic agents are widely used to reduce vasospasm and enhance microvascular anastomosis in reconstructive microsurgery. In this study, thermo-responsive hydrogel (CNH) was fabricated by grafting chitosan (CS) and hyaluronic acid (HA) to poly(N-isopropylacrylamide) (PNIPAM). Papaverine, an anti-spasmodic agent, was then loaded to evaluate its effect on rat skin flap survival. Post-operative flap survival area and water content of rat dorsal skin flap were measured at 7 days after intradermal application of control hydrogel (CNHP0.0) and papaverine loaded hydrogel (CNHP0.4). Tissue malondialdehyde (MDA) content and superoxide dismutase (SOD) activity was measured using enzyme linked immunosorbent assay (ELISA) to determine oxidative stress in flaps. Hematoxylin and eosin (H&E) staining and immunohistochemistry (IHC) were performed to evaluate flap angiogenesis and inflammatory markers. Results showed that CNHP0.4 hydrogel could reduce tissue edema (35.63 ± 4.01%), improve flap survival area (76.30 ± 5.39%), increase SOD activity and decrease MDA content. Consequently, it also increased mean vessel density, upregulated expression of CD34 and VEGF, decreased macrophage infiltration, and reduced CD68 and CCR7 expression based on IHC staining. Overall, these results indicate that CNHP0.4 hydrogel can enhance angiogenesis with anti-oxidative and anti-inflammatory effects and promote skin flap survival by preventing vascular spasm.

Published: May 2023

AbstractBreast cancer screening recommendations for transgender and gender diverse (TGD) patients have only been recently developed and many primary care practitioners (PCPs) are unaware of these specific recommendations. The aim of this study is to assess the level of familiarity and knowledge PCPs have with breast cancer screening recommendations for TGD patients. An anonymous survey was distributed to primary care physicians, primary care advanced practice practitioners, and internal medicine and family medicine residents at three academic medical systems in the United States (Mayo Clinic, University of Michigan, University of Texas – Medical Branch). Survey questions assessed the familiarity and knowledge base of TGD breast cancer screening recommendations, training and experience with TGD patients, and basic demographics of the practitioners. Of the 95 survey respondents, only 35% of respondents were aware that breast cancer screening recommendations for TGD patients existed. PCPs who had increased transgender specific health care training and direct clinical exposure to TGD patients demonstrated significantly higher levels of screening recommendation awareness. Two-thirds of respondents received TGD specific medical education during training or medical career and those who had increased transgender specific medical education or direct clinical exposure to TGD patients demonstrated significantly higher levels of screening recommendation awareness. Awareness of breast cancer screening recommendations for TGD patients is low among PCPs and varied based on the practitioner’s prior TGD education and experience. Up-to-date breast cancer screening recommendations for TGD patients should be readily available across multiple platforms, target key audiences, and integrated into transgender health educational curriculums to maximize awareness of these important recommendations.

AbstractThe present observational study was conducted to uncover potential differences in the risk of experiencing high occupational heat strain during agriculture work between migrants and their native coworkers, as well as to elucidate the factors that may contribute to such differences. The study took place over the period from 2016 through 2019 and involved monitoring 124 experienced and acclimatized individuals from high-income (HICs), upper-middle-income (UMICs), as well as lower-middle- and low-income (LMICs) countries. Baseline self-reported data for age, body stature, and body mass were collected at the start of the study. Second-by-second video recordings throughout the work shifts were captured using a video camera and were used to estimate workers’ clothing insulation, covered body surface area, and body posture, as well as to calculate their walking speed, the amount of time they spent on different activities (and their intensity) and unplanned breaks throughout their work shifts. All information derived from the video data was used to calculate the physiological heat strain experienced by the workers. The core temperature of migrant workers from LMICs (37.81 ± 0.38 °C) and UMICs (37.71 ± 0.35 °C) was estimated to be significantly higher compared to the core temperature of native workers from HICs (37.60 ± 0.29 °C) (p < 0.001). Moreover, migrant workers from LMICs faced a 52% and 80% higher risk for experiencing core body temperature above the safety threshold of 38 °C compared to migrant workers from UMICs and native workers from HICs, respectively. Our findings show that migrant workers originating from LMICs experience higher levels of occupational heat strain, as compared to migrant workers from UMICs and native workers from HICs, because they take fewer unplanned breaks during work, they work at a higher intensity, they wear more clothing, and they have a smaller body size.
Should expressivists go global?
Authors: Simpson Matthew 
Published: May 2023

AbstractMoral expressivists think that moral thoughts and sentences don’t represent or describe the world, at least not in any interesting sense. Global expressivists think that no thoughts or sentences represent the world; local expressivists think that some do and others don’t. Huw Price has influentially argued that local expressivism collapses into global expressivism, due both to the effects of minimalist theories of representation and similar concepts, and to an unappreciated consequence of the success of specific expressivist theories like moral expressivism. In this paper I argue that Price’s arguments don’t succeed. While they can be fixed, doing so makes them miss their intended target. Local expressivists should therefore not be worried by Price’s arguments.
Degree completion among students with an immigrant background in short-cycle welfare-oriented professional education
Authors: Hundebo Pål Oskar 
Published: May 2023

AbstractThis article examines degree completion among students with an immigrant background who enrolled in professional bachelor’s degree programmes in early childhood or teacher education, nursing, or social work. By using the high-quality Norwegian register data covering national cohorts of students enrolled in higher education between 1990 and 2014, the analysis indicates that immigrants and native-born descendants of immigrants were less likely to complete these study programmes, compared with native majority students. Explanations for this could be linked to ethnic minorities being inadequately integrated—socially and academically—in these study programmes and therefore less able and/or motivated to stay enrolled until graduation. In all four professional study programmes, students with an immigrant background had comparatively higher probabilities of transferring to other study programmes or dropping out of higher education altogether. On the positive side, minority-majority gaps in degree completion were considerably smaller for those who achieved academically well in these professional study programmes, measured as high first-year GPAs. However, it is quite alarming that immigrants and immigrant descendants who achieved poor academic results were substantially less likely to complete a degree than native majority students with correspondingly poor results.

AbstractOral factor Xa (FXa) inhibitors significantly reduce incidence of stroke and thromboembolic events in patients with atrial fibrillation or venous thromboembolism. Due to various factors and the lack of a randomized controlled trial comparing andexanet alfa to usual care, non-specific replacement agents including 4 F-PCC are still used off-label for FXa inhibitor bleed management. Clinical and mortality data were extracted from the inpatient medical data and Veteran Affairs (VA) vital status files over the time of March 2014 through December 2020. Propensity score-weighted models were used for this retrospective cohort study using data from the Veterans Affairs Informatics and Computing Infrastructure (VINCI). The study included 255 patients (85-andexanet alfa and 170-4 F-PCC) exposed to an oral factor Xa inhibitor and hospitalized with an acute major, gastrointestinal (GI), intracranial (ICH) or other bleed. In-hospital mortality was significantly lower in the andexanet alfa cohort compared to the 4 F-PCC cohort (10.6% vs. 25.3%, p = 0.01). Propensity score–weighted Cox models reveal a 69% lower hazard of in-hospital mortality for those treated with andexanet alfa (HR 0.31, 95% CI 0.14–0.71) compared to those treated with 4 F-PCC. Additionally, those treated with andexanet alfa had a lower 30-day mortality rate and lower 30-day hazard of mortality in the weighted Cox model (20.0% vs. 32.4%, p = 0.039; HR 0.54, 95% CI 0.30–0.98) compared to those treated with 4 F-PCC. Among 255 US veterans with major bleeding in the presence of an oral factor Xa inhibitor, treatment with andexanet alfa was associated with lower in-hospital and 30-day mortality than treatment with 4 F-PCC.

AbstractThe aim of this study was to investigate the effects of substitution moringa seed cake (MSC) for soybean meal (SBM) in calves’ rations on blood parameters and growth performance. Thirty-two crossbred calves (232 ± 6.75 kg) were divided into 4 groups (8 animals each). All animals were fed a ration of 30% Egyptian clover + 10% corn silage and 60% concentrate mix (CM). The first group (MSC0%) was fed the CM without any MSC (control), while the second (MSC25%), the third (MSC50%), and the fourth (MSC100%) groups were fed on 25%, 50% and 100% MSC by replacing SBM in CM respectively. Results revealed that MSC50% increased (P ≤0.05) most of nutritive values and digestibility compared with the tested groups. Also, MSC50% reduced (P ≤0.05) feed conversion of dry matter (DM), total digestible nutrient (TDN) and digestible energy (DE) compared to the tested groups. Also, MSC50% increased the total weight gain and net revenue by 13.50% and 22.75%, respectively, compared to control. While MSC100% lowered the total weight gain and net revenue by -7.67% and -4.20%, respectively, compared to control. Total protein and glucose were increased (P ≤0.05) by rations with 25% and 50% MSC compared with MSC (0% and100%). Moreover, adding MSC to animals’ rations at different levels improved most of blood metabolites compared to control. Conclusion, moringa seed cake can be used as an alternative protein source to soybean meal in fattening calves rations at level up to 50% to improve growth performance and net profit without adverse effects.

AbstractSpent tire rubber-derived chars and their corresponding H3PO4 and CO2-activated chars were used as adsorbents in the recovery of Pb(II) ion and (W(VI)) oxyanion from synthetic solutions. The developed chars (both raw and activated) were thoroughly characterized to have insight about their textural and surface chemistry properties. H3PO4-activated chars presented lower surface areas than the raw chars and an acidic surface chemistry which affected the performance of these samples as they showed the lowest removals of the metallic ions. On the other hand, CO2-activated chars presented increased surface areas and increased mineral content compared to the raw chars, having presented higher uptake capacities for both Pb(II) (103–116 mg/g) and W(VI) (27–31 mg/g) ions. Cation exchange with Ca, Mg and Zn ions was appointed as a mechanism for Pb removal, as well as surface precipitation in the form of hydrocerussite (Pb3(CO3)2(OH)2). W(VI) adsorption might have been ruled by strong electrostatic attractions between the negatively charged tungstate species and the highly positively charged carbons’ surface.The results shown in this work allow concluding that the valorisation of spent tire rubber through pyrolysis and the subsequent activation of the obtained chars is an alternative and a feasible option to generate adsorbent materials with a high uptake capacity of critical metallic elements.
