Understanding the sources of primary production supporting marine food webs is important for conserving critical habitats. However, the importance of allochthonous versus autochthonous production is often unclear. We identify the sources of primary production supporting three species of predatory fish (Lutjanus carponotatus, Lutjanus fulviflamma, and Lethrinus punctulatus) in the Dampier Archipelago, Western Australia. The proportions of mangrove, seagrass, macroalgae, and suspended particulate organic matter (SPOM) assimilated by fish of different life-history stages and from different habitats were determined using stable isotopes and Bayesian mixing models. While contributions of sources varied among species and habitats, we found that SPOM was an important energetic resource for both adults and juveniles of all three fish species. Juvenile L. carponotatus and L. punctulatus inhabiting macroalgal habitats assimilated more seagrass- and macroalgae-derived material than fish from coral or mangrove habitats, while reliance on mangrove carbon was generally limited overall. Assimilation of macrophyte-derived material decreased throughout ontogeny for L. carponotatus, while L. fulviflamma relied on a combination of SPOM and seagrass into adulthood. The contribution of macroalgae and SPOM to the diets of juvenile L. punctulatus and L. carponotatus from macroalgal habitats varied spatially but was unrelated to seascape configuration, habitat quality, or hydrodynamic conditions. While mixing models suggested a modest degree of trophic connectivity, cross-habitat trophic subsidies provided by macrophytes play a minor role in supporting the studied fish of either life-history stage. Instead, microalgal production predominantly fuels the productivity of predatory fish in this turbid, macrotidal system.

Published: September 2024

Situational Judgement Tests (SJTs) are popular to screen for social skills during undergraduate medical admission as they have been shown to predict relevant study outcomes. Two different types of SJTs can be distinguished: Traditional SJTs, which measure general effective behavior, and construct-driven SJTs which are designed to measure specific constructs. To date, there has been no comparison of the predictive validity of these two types of SJTs in medical admission. With the present research, we examine whether the HAM-SJT, a traditional SJT, and the CD-SJT, a construct-driven SJT with an agentic and a communal scale, administered during undergraduate medical admission can predict OSCE (i.e., objective structured clinical examination) performance in a low-stakes (nLS = 159) and a high-stakes (nHS = 160) sample of medical students. Results showed a moderate positive relation between the communal scale of the CD-SJT and performance in OSCE stations with trained patients in the high-stakes sample (r =.20, p =.009). This SJT had also an incremental value in predicting the OSCE performance above and beyond GPA (i.e., grade point average), a science test (i.e., HAM-Nat), and gender (ß = 0.18, 95% CI [0.03; 0.33], p =.020). That is, individuals who chose more communal behavioral responses in the SJT were rated more favorably in interactions with trained patients in the OSCE. A comparable correlation coefficient was observed for the HAM-SJT when controlling for range restriction due to admission (rraw = 0.14 vs. rcontrolled = 0.20). Our research provides a first indication for the predictive validity of construct-driven SJTs in high-stakes undergraduate medical admission.

Rates of HIV acquisition remain high among adolescent girls and young women (AGYW) in sub-Saharan Africa. We explored South African, Ugandan, and Zimbabwean AGYW’s experiences in a crossover trial of two HIV prevention products: Daily oral pre-exposure prophylaxis pills and a monthly dapivirine vaginal ring. A subset of participants (n = 25) across all sites completed up to three serial in-depth interviews (SIDIs). The SIDIs explored barriers to product use, coping strategies, and the resulting outcomes. Coded textual data were analyzed using a product acceptability conceptual framework. Participants in the SIDIs described managing the array of challenges they encountered through formal adherence support, strategic product disclosure, and personally adapted strategies. For both products, perceived discreetness of the product and decision-making around disclosure was an important component of participants’ narratives. Participants tailored their coping strategies based on available personal resources (e.g., cell phone alarms for PrEP reminders, social support through disclosure) or study provided resources (e.g., encouragement from staff, adherence groups). Notably, challenges participants encountered with each product during the crossover period helped inform product selection during the choice period. Our findings suggest that—even in a context where AGYW have access to several options for HIV prevention—challenges to consistent product use remain, but accessible support mechanisms and informed choice can help mitigate these challenges. Enacting that choice may also empower AGYW to reach their short and long-term life goals—including for HIV prevention. (NCT03593655, 20th July 2018).

Authors: Ferraro Giovanna , Iovanella Antonio , Ramponi Alessandro , Rotundo Giulia
Published: September 2024

Patents are important sources of technical knowledge because they offer a wealth of information on innovations and technological developments. This paper focuses on Fintech-related patent certificates in order to examine the technical trends in this particular sector and discuss the factors influencing technological advancement. The data were retrieved through the World Intellectual Property Organization database, considering selected keywords. Through the network analysis, we identify five relevant technological clusters that allow us to detect the technological substrate underlying the corresponding cluster. The Bass diffusion model permits the observation of the technological trajectories of each cluster, outlining the diffusion patterns. Furthermore, particular attention is given to the developing technologies defined as "green", and we describe how these trends have changed over time and predict their future technological trajectory. Our findings provide an in-depth analysis of the Fintech patent landscape, highlighting the connections between the different technologies. It also allows us to assess the technological leadership of companies and the technological life cycle that describes the diffusion patterns.
Ticagrelor and Statins: Dangerous Liaisons?
Authors: Rocca Bianca , Bigagli Elisabetta , Cerbai Elisabetta
Published: September 2024

Polypharmacy is often necessary in complex, chronic, comorbid and cardiovascular patients and is a known risk factor for potential drug-drug interaction (DDI) that can cause adverse reactions (toxicity or therapeutic failure). Anti-thrombotic drugs (largely low-dose aspirin and a platelet P2Y12 receptor inhibitor) and statins are among the most co-administered drugs in cardiovascular patients. Ticagrelor is a selective antagonist of the platelet P2Y12-receptor, highly effective in inhibiting platelet aggregation and bio-transformed by the CYP3A4 and substrate of transporters, such as the breast cancer resistance protein (BCRP). Statins have different pharmacokinetic profiles; some undergo CYP3A4-mediated metabolism; rosuvastatin is primarily metabolized by the CYP2C9; and they have different affinities for drug transporters. Rhabdomyolysis is a very rare but severe adverse event, which is specific for statins which can be triggered by DDIs that increase statin’s concentrations through blockade of their biotransformation and/or elimination. Large pharmacovigilance and small observational studies reported increased rhabdomyolysis in patients treated with some statins and ticagrelor but not aspirin, clopidogrel or prasugrel. Recent studies in vitro, pharmacokinetic trials and in silico drug modelling identified and validated the BCRP inhibition by ticagrelor, as a mechanism contributing to the DDI with statins, as ‘victim’ drugs, leading to increased rhabdomyolysis. While the clinical impact of this DDI deserves further investigation, a careful evaluation should be advised when ticagrelor is co-prescribed with some statins.
Parent–Child Mealtime Conversations Stimulated with Decorated Tableware
Authors: Kucirkova Natalia , Bubikova-Moan Jarmila
Published: September 2024

This explorative qualitative study investigated how families engage in mealtime conversations supported with decorated plates that were specially designed to promote family conversations. Our aim was to examine the main thematic and discursive patterns that naturally occurred in these conversations. Six Norwegian families of pre-school children aged 3–6 years were provided with five decorated plates and asked to audio-record their conversations during a meal. Transcripts of the audio-recordings were analysed with manifest content-related analysis, followed by an abductive analysis and a mapping of the main discourse types and interactional patterns. We demonstrate that the conversations displayed great thematic heterogeneity and represented a continuum of extended and non-extended talk, ranging from basic labelling and vocabulary recall to narration, explanation and argumentation. Variable engagement levels among the participants were also noted. We argue that decorated tableware can serve as a valuable tool for studying linguistic input and the nature of adult–child conversations during mealtimes at home and beyond.
Self-Regulated Learning Interventions for Pre-service Teachers: a Systematic Review
Authors: Ortube Alazne Fernández , Panadero Ernesto , Dignath Charlotte
Published: September 2024

Self-regulated learning (SRL) is a key competence for pre-service teachers to develop, both for their own activities as learners and for their future activities as teachers. Therefore, it is crucial to understand how pre-service teachers can be supported in acquiring SRL competence in their initial training. To reach this aim, we conducted a systematic review of SRL interventions for pre-service teachers. Sixty-six intervention studies fulfilled the inclusion criteria. We explored three aspects of those SRL interventions, and how they moderate the interventions’ effectiveness: (1) the theoretical and practical underpinnings of SRL, (2) whether the intervention aimed to promote SRL learning and/or teaching of SRL, and (3) the intervention’s pedagogical characteristics and content related to the SRL professional competences. We found that the most effective SRL interventions (1) focused the training on one or two SRL areas (especially cognition and metacognition); (2) when targeted both, SRL learning and teaching of SRL, pre-service teachers’ SRL skills improved as well as their pedagogical skills; and (3) addressed direct and implicit SRL instruction, inside which self-assessment of learning and teaching practices appear as an effective pedagogical method. We derive implications from our findings for designing effective SRL interventions for prospective teachers.
Sound in mode on: how sound stimuli influence customer engagement?
Authors: Valenzuela-Gálvez E. Sophía , González-Benito Óscar , Garrido-Morgado Álvaro
Published: September 2024

The objectives of this research are as follows: (i) to study whether the presence of sound stimuli influences customer engagement; (ii) to assess this effect on different dimensions of customer engagement (sensory experience, approach-avoidance response, and emotional response); and (iii) to study whether product type and customer involvement moderate the effect of sound on customer engagement. This research analyzes the effect of two different sound stimuli for two different product types on two digital channels. The experimental design for Study 1 is a 2 sound (sound associated with the product vs. no sound) × 2 product type (hedonic vs. utilitarian) displayed in a social network (Instagram) environment. The experimental design for Study 2 is a 2 sound (voiceover vs. no sound) × 2 product type (hedonic vs. utilitarian) displayed in a blog. Both studies additionally incorporate measured variables, with a particular focus on customer involvement (low and high). A total of 512 participants interacted with a condition and then completed a questionnaire. The presence of sound increases customer engagement in the sensory experience and approaching response. The interaction of sound (voice-over) and the hedonic product positively influences the emotional response, and customer involvement negatively moderates the influence of sound on the sensory experience.
Bregman Proximal Linearized ADMM for Minimizing Separable Sums Coupled by a Difference of Functions
Authors: Pham Tan Nhat , Dao Minh N. , Eberhard Andrew , Sultanova Nargiz
Published: September 2024

In this paper, we develop a splitting algorithm incorporating Bregman distances to solve a broad class of linearly constrained composite optimization problems, whose objective function is the separable sum of possibly nonconvex nonsmooth functions and a smooth function, coupled by a difference of functions. This structure encapsulates numerous significant nonconvex and nonsmooth optimization problems in the current literature including the linearly constrained difference-of-convex problems. Relying on the successive linearization and alternating direction method of multipliers (ADMM), the proposed algorithm exhibits the global subsequential convergence to a stationary point of the underlying problem. We also establish the convergence of the full sequence generated by our algorithm under the Kurdyka–Łojasiewicz property and some mild assumptions. The efficiency of the proposed algorithm is tested on a robust principal component analysis problem and a nonconvex optimal power flow problem.
A Community-Informed Maternal and Infant Health Needs Assessment in Alabama
Authors: Horan Holly , Locke Emily , Bradley Lilanta Joy
Published: September 2024

Background

Maternal mortality is a global clinical and public health crisis. Researchers and leading organizations have highlighted the need for local partnerships to implement evidence-based strategies to mitigate poor outcomes. Alabama has the third highest maternal mortality rate in the nation. Research on the complexity of maternity mortality is strengthening, but poor outcomes in Alabama persist and there is limited data highlighting the perspectives of those on the frontlines of providing and receiving care.

Purpose

We conducted a qualitative, statewide, community-informed, maternal and infant health research assessment with physicians, providers, professionals, and birthing persons to identify challenges and solutions to addressing the states’ poor perinatal health outcomes.  

Methods

Data were collected using a four-phase, research design that included semi-structured interviews, focus groups, one state-wide data sharing event, and five regional data sharing events. Data were collected between January 2020 and October 2021. The data were analyzed using consensus coding and thematic analysis.

Main Findings

Fifty-nine (N = 59) individuals participated. Three themes emerged: 1) “They were making me feel so overlooked.”: A disconnect between perinatal healthcare services and patient needs; 2) “That shouldn’t be something you have to ask for.”: Limitations to providing respectful perinatal healthcare; and 3) “If they work together, they can have all the tools they need.”: Building a case for collaborative care.

Conclusions

Participants advocated for a collaborative perinatal healthcare model that focuses on the provision of respectful, quality perinatal healthcare. Our approach can be applied across contexts and used to support the effective implementation of contextually relevant maternity care practices.
The Early Solar System and Its Meteoritical Witnesses
Authors: Jacquet Emmanuel , Dullemond Cornelis , Drążkowska Joanna , Desch Steven
Published: September 2024

Meteorites, and in particular primitive meteorites (chondrites), are irreplaceable probes of the solar protoplanetary disk. We review their essential properties and endeavour to place them in astrophysical context. The earliest solar system solids, refractory inclusions, may have formed over the innermost au of the disk and have been transported outward by its expansion or turbulent diffusion. The age spread of chondrite components may be reconciled with the tendency of drag-induced radial drift if they were captured in pressure maxima, which may account for the non-carbonaceous/carbonaceous meteorite isotopic dichotomy. The solid/gas ratio around unity witnessed by chondrules, if interpreted as nebular (non-impact) products, suggests efficient radial concentration and settling at such locations, conducive to planetesimal formation by the streaming instability. The cause of the pressure bumps, e.g. Jupiter or condensation lines, remains to be ascertained.

Published: September 2024

The study quantified breed effects and putative non-additive genetic variation for quantitative and qualitative slaughter and skin traits involving three ostrich breeds: South African Black (SAB), Zimbabwean Blue (ZB), and Kenyan Red (KR) ostriches. Such data from contemporary slaughter groups with all three pure breeds represented were analyzed together (SAB: n = 457; ZB: n = 74; KR: n = 50). Two 2 × 2 diallel crossbreeding designs were used to assess crosses of ZB and KR birds with the SAB strain. Subsequently, the data from SAB, ZB and their reciprocal crosses, slaughtered together; as well as the data from SAB and KR ostriches, along with their reciprocal crosses, respectively, were analyzed separately. ZB and KR birds outperformed SAB birds for most size-related slaughter and skin traits. Linear contrasts were used to distinguish the effects of breed, heterosis, and the dam line. For the ZB x SAB design, additive breed effects were significant for slaughter weight (10.4%), crust skin size (3.9%) and nodule shape score (1.6%) (all P < 0.05). Significant heterosis were found for slaughter weight (4.3%), crust skin size (1.7%) and nodule size score (3.7%) (P < 0.05). Dam line effects were observed for skin weight (4.1%) and hair follicle score (4.1%). In the KR x SAB design, additive breed effects were like outcomes for the ZB x SAB design. Heterosis estimates were significant (P < 0.05) for slaughter weight (5.8%), crust skin size (2.9%), crown length (1.7%) and nodule size score (4.4%). Dam line effects were significant for slaughter weight (3.7%) and nodule size score (3.8%). In conclusion, ZB and KR birds outperformed their SAB contemporaries for size and size-related traits. Crossbreeding with these genotypes could improve some size-related traits over the mid-parent value of purebreds.

Published: September 2024

Per- and polyfluoroalkyl substances (PFAS) have become an environmental issue worldwide. A first step to assessing potential adverse effects on fish populations is to determine if concentrations of concern are present in a region and if so, in which watersheds. Hence, plasma from adult smallmouth bass Micropterus dolomieu collected at 10 sites within 4 river systems in the mid-Atlantic region of the United States, from 2014 to 2019, was analyzed for 13 PFAS. These analyses were directed at better understanding the presence and associations with land use attributes in an important sportfish. Four substances, PFOS, PFDA, PFUnA, and PFDoA, were detected in every plasma sample, with PFOS having the highest concentrations. Sites with mean plasma concentrations of PFOS below 100 ng/ml had the lowest percentage of developed landcover in the upstream catchments. Sites with moderate plasma concentrations (mean PFOS concentrations between 220 and 240 ng/ml) had low (< 7.0) percentages of developed land use but high (> 30) percentages of agricultural land use. Sites with mean plasma concentrations of PFOS > 350 ng/ml had the highest percentage of developed land use and the highest number PFAS facilities that included military installations and airports. Four of the sites were part of a long-term monitoring project, and PFAS concentrations of samples collected in spring 2017, 2018, and 2019 were compared. Significant annual differences in plasma concentrations were noted that may relate to sources and climatic factors. Samples were also collected at two sites for tissue (plasma, whole blood, liver, gonad, muscle) distribution analyses with an expanded analyte list of 28 PFAS. Relative tissue distributions were not consistent even within one species of similar ages. Although the long-chained legacy PFAS were generally detected more frequently and at higher concentrations, emerging compounds such as 6:2 FTS and GEN X were detected in a variety of tissues.

Published: September 2024

Water is an important component of life and plays a vital role in human and animal lives, and because of these essential roles of water to life, access to quality water and in adequate quantity becomes imperative. Subsequently, water/wastewater systems have become established as reservoirs of antimicrobial resistance determinants in the environment. In this study, we carried out the synthesis and characterization of magnetite nanoparticles for use in the removal of genomic DNA of antibiotic resistant Escherichia coli isolate in aqueous system. The synthesis of this nanoparticle was achieved by using precipitation method and characterization of the material was conducted by using Fourier transform infrared spectroscopy (FTIR), scanning electron spectroscopy (SEM), electron diffraction spectroscopy (EDS), and vibrating sample magnetometry (VSM). The SEM analysis revealed that this material is spherical in shape, while the FTIR spectra revealed Fe–O vibrational band at ~ 450 cm−1 confirming the success of the synthesis of this material. The magnetite nanomaterial showed efficiency for the removal of the bacterial DNA from water with a maximum removal capacity of 45.5 ng g−1. The effect of pH (qe max = 55 ng g−1 @ pH = 10), time (qt max @ 180 min), DNA concentration (DNA concentration of 185 ng/mL, qe max = 45.5 ng g−1), and adsorbent weight (% adsorption max = 61.65% @ 0.025 g) suggest that adsorption conditions influence the removal of DNA by this material. In addition, kinetic study shows that the removal of bacterial DNA obeyed pseudo 2nd order indicating that adsorption process was achieved by bimolecular interaction between magnetite and antibiotics resistant bacterial DNA. We conclude that magnetite nanoparticle appears to be a potential candidate for the removal of nucleic acids and antimicrobial resistance determinants in water/wastewater treatment.
Effects of recirculation dredging on density, strength, settling and oxygen concentration of fluid mud in the port of Emden
Authors: Chamanmotlagh Fatemeh , Kirichek Alex , Gebert Julia
Published: September 2024

Purpose

Recirculation dredging is a port maintenance concept developed in the Port of Emden, Germany to create a navigable fluid mud layer. This study investigates the effects of recirculation on key sediment properties, including density, yield stress, and oxygen concentration.

Methods

Six field monitoring surveys were carried out at two locations at different times of the year to assess changes before and after recirculation. Bathymetry, bulk density, yield stress, and oxygen concentration profiles were measured in situ. The settling properties and oxygen concentration levels on collected fluid mud samples were analyzed in the laboratory.

Results

The investigation reveals minimal changes in the density of recirculated fluid mud. However, the post-recirculation measurements showed a decrease in yield stress, ranging from 18 to 51% at Große Seeschleuse (GS) and 36% to 52% at Industriehafen (IH). The yield stress and density vary depending on the frequency of dredging. After structural density (1166 kg m−3 in GS and 1173 kg m−3 in IH), the yield stress of fluid mud increased exponentially. Therefore, monitoring of the yield stress is important for recirculation. A slight increase in oxygen concentration was observed post-recirculation, especially during winter. Yet, the rapid decline in oxygen levels post-mixing in the laboratory showed that sustaining long-term elevated oxygenation levels is not feasible by recirculation dredging alone.

Conclusions

The findings highlight the effectiveness of the recirculation on the yield stress, density, and oxygen concentration of fluid mud and illustrate the importance of considering both density and yield stress in sediment management practices. Future research should address the temporal evolution of density, yield stress, and oxygen levels following a dredging intervention and the influence of extracellular polymeric substances (EPS) and organic matter decay on sediment behavior.
Subjective Well-Being of Parents and Childless People in Older Age in Germany
Authors: Tolkamp Maximilian , Pollmann-Schult Matthias
Published: September 2024

The growing number of older childless individuals in Western societies has raised concerns about their subjective well-being. In this study, we scrutinize the subjective well-being of parents and childless individuals aged 60 years and older. We examine subjective well-being as a multi-dimensional construct encompassing life satisfaction, positive affect, and negative affect. Based on the value-of-children approach, we hypothesize that childless individuals experience lower subjective well-being than parents and that the disparity in well-being differs with age, gender, and the quality of the parent-child relationship. For our analysis, we use data from a nationally representative sample of adults aged 60 years and older (n = 10,682) drawn from the German Ageing Survey. Our findings from random effects regression models show that childless individuals report lower life satisfaction, less positive affect, and more negative affect than parents. These associations are larger for men than for women but do not vary significantly across age groups. Furthermore, our results suggest that the benefits of parenthood strongly depend on the quality of the parent-child relationship. Childless people report lower subjective well-being than parents with a close emotional bond with their children, but similar or even higher subjective well-being than parents with an emotionally distant parent-child relationship. In sum, our study indicates that childless people experience, on average, lower well-being across all three dimensions of subjective well-being in older age. However, under specific circumstances, childless individuals may fare better than parents.
Effects of Metribuzin on Soil Microbiome and Weed Management Under Varying Planting Practices and Potato Seed Dormancy
Authors: Kilonzi J. M.
Published: September 2024

Weed infestation in potato field has become a major concern to smallholder farmers and environment, requiring sustainable intervention. This study aimed to determine (i) whether metribuzin application rate (0, 0.5, 1 (standard), 1.5, and 2 kg ai ha−1) has effects on soil microbes and soil nutrients in the short term using potted soil and (ii) the influence of potato seed dormancy (short; Shangi variety and long; Unica variety) and planting technique (surface, ridge, or furrow planting) on the efficacy of weed management practice (metribuzin (480 g L−1) herbicide and hoeing) in the field. Bacterial colony counts were recorded upon isolation from the potted soil. Soil nutrients were also analysed before and after metribuzin treatment. Data on crop growth (height and stem count), weed abundance, yield, costs, and revenues were recorded from a field experiment. Morphologically distinct bacterial strains were tested for Gram reaction and response to carbon utilization using analytical profile index kits (API 50 CH and 20 NE). In total, nine distinct bacterial strains were isolated and all were Gram positive, with variation in response to carbon substrates. Concentration of 2.0 kg a.i ha−1 significantly (p ≤ 0.05) reduced bacterial count in the first day, followed by an increase in the subsequent incubation days, while 1.0 and 1.5 kg a.i ha−1 concentrations had the highest colony development index and species richness. Significant effects of metribuzin on soil pH, total N, and total organic C in the short term were revealed. Notably, weedy plots had the highest Shannon weed index. Weeds reduced stem count and height growth by 57% and 62% respectively. Plots with Shangi had 9.8% lower weed count than those with Unica and hence higher yield was recorded from the former. While surface planting had the lowest weed control efficacy, crop growth attributes, and yield, furrow and ridge planting were not significantly different. Weed abundance and crop growth attributes in metribuzin and hand-hoed plots did not differ significantly, yet hoeing resulted in 5.30 t ha−1 above that obtained from plots managed using metribuzin. Higher dry matter and tuber yield were observed from hoed plots with Shangi planted in furrow or ridge. Use of metribuzin resulted in higher net benefit ratio and marginal rate of return than hand hoeing. The results reveal that use of metribuzin early and later in the potato growing phase can minimize weed infestation, but the efficacy depends on planting method and seed dormancy.

This research paper investigates new and first insights into the magnetic and magnetocaloric properties of one-dimensional (1D) cobalt ferrite CoFe2O4 (CFO) nanofibers (NFs) fabricated using a sol–gel-based electrospinning technique, focusing in particular on their behavior at low temperatures for specific applications. The microstructural, structural, magnetic, and magnetocaloric properties of the calcined CFO NFs were explored. The microstructure of the NFs, with an average diameter of 210 nm, was examined by scanning and transmission electron microscopy (SEM, TEM). The x-ray diffraction (XRD) of the CFO NFs showed a pure cubic close-packed (ccp) spinel crystalline structure with the Fd$$\overline{3}$$

m space group. The Raman spectroscopic studies further confirm the cubic inverse spinel phase. The magnetic properties were explored as a function of temperature, ranging from 10 K to 300 K, and ferromagnetic behavior was observed with the highest saturation magnetization of 75.87 emu/g and coercivity of 723 Oe at room temperature. The variation of the magnetic entropy was measured indirectly using the Maxwell approach with an increasing magnetic field. A maximum of $$\left| {\Delta S} \right|$$

At 180 K, the associated adiabatic temperature change, ΔTmax, was 0.93 K, with a large RCP value of 7.58 J/kg, which is reasonably high for the corresponding nanoparticles (NPs). This work suggests that 1D CFO NFs offer a promising route for the production of nanostructured magnetic materials, potentially impacting various electronic and electromagnetic device applications at low temperatures.

Published: September 2024

Patients hospitalized in Internal Medicine Units (IMUs) may frequently experience both an increased risk for thrombosis and bleeding. The use of risk assessment models (RAMs) could aid their management. We present a post-hoc analysis of the FADOI-NoTEVole study, an observational, retrospective, multi-center study conducted in 38 Italian IMUs. The primary aim of the study was to evaluate the predictors associated with the prescription of thromboprophylaxis during hospitalization. The secondary objective was to evaluate RAMs adherence. Univariate analyses were conducted as preliminary evaluations of the variables associated with prescribing pharmacological thromboprophylaxis during hospital stay. The final multivariable logistic model was obtained by a stepwise selection method, using 0.05 as the significance level for entering an effect into the model. Thromboprophylaxis was then correlated with the RAMs and the number of predictors found in the multivariate analysis. Thromboprophylaxis was prescribed to 927 out of 1387 (66.8%) patients with a Padua Prediction score (PPS) ≥ 4. Remarkably, 397 in 1230 (32.3%) patients with both PPS ≥ 4 and an IMPROVE bleeding risk score (IBS) < 7 did not receive it. The prescription of thromboprophylaxis mostly correlated with reduced mobility (OR 2.31; 95% CI 1.90–2.81), ischemic stroke (OR 2.38; 95% CI 1.34–2.91), history of previous thrombosis (OR 2.46; 95% CI 1.49–4.07), and the presence of a central venous catheter (OR 3.00; 95% CI 1.99–4.54). The bleeding risk assessment using the IBS did not appear to impact physicians’ decisions. Our analysis provides insight into how indications for thromboprophylaxis were determined, highlighting the difficulties faced by physicians with patients admitted to IMUs.
Unlocking the secrets of family firms: exploring dialogue capacity through a secularization perspective in Germany, Austria, and Switzerland

Published: September 2024

Family firms (FFs) are characterized by their unique emphasis on specific beliefs and values (BaV). Although literature acknowledges the significance of BaV for firm behavior and management decisions, little is known about their religious and secular sources. Following secularization theory and post-secular society, the impact of religion in developed societies such as the DACH region (Germany, Austria, Switzerland) remains ambiguous, challenged by both secularization and religious revival. We address this research gap by exploring the religious and secular sources of BaV through FFs’ dialogue capacity. Our qualitative-empirical study builds on semi-structured interviews with 21 large FFs from the DACH region, covering mostly family CEOs, and secondary data. Using an inductive approach, we identify FFs where religion remains significant, even as their dialogue capacity undergoes transformation. Secularization necessitates that religious sources to adapt to the secular business context. Thus, our findings do not conform to the open dialogue claimed by post-secular society. Additionally, the proposed dichotomous separation into a religious sphere and a secular sphere does not correspond to the actual landscape of FFs. Instead, three different shades of FFs emerge, which demonstrate unique dynamics in their dialogue capacity. This paper provides novel in-depth insights on BaV in FFs and is among the first empirical studies on secularization and post-secular society from a business perspective. Furthermore, it contributes a process model of FFs’ dialogue capacity and proposes avenues for further research.

Although water-based paint is increasingly being advocated as environmentally friendly, it is more susceptible to biodeterioration during processing, preparation, and storage. Therefore, sufficient proactive measures are urgently needed to control and prevent microbial contamination along the production chain. The experimental setup comprised the investigation of the paints (e.g., pH, water content, FTIR) as well as the isolation and identification of bacterial and fungal contaminants via Sanger sequencing and MALDI-TOF MS. We identified well-known paint degraders such as Bacillus and Pseudomonas spp., however also less frequently abundant species like Rhodococcus. While the diversity within gram-negative bacteria turned out to be higher compared with gram-positive ones, the latter were predominant in paint and their immediate ambience, indicating that they are more resistant toward the applied measures. Our results emphasize the need for manufacturers to apply tailored measures against paint spoilage as a prerequisite for further product- and production-specific preservation concepts.
An anti-money laundering authority for the European Union: a new center of gravity in AML enforcement
Authors: Tosza Stanisław , Voordeckers Olivier
Published: September 2024

The establishment of an Anti-Money Laundering Authority (AMLA) heralds a milestone in the European Union’s (EU) institutional framework for the enforcement of anti-money laundering and countering the financing of terrorism (AML/CFT) rules. This contribution explores the competence and powers of the new AML/CFT supervisor. While AMLA is a true enforcement actor with investigative and sanctioning powers to address breaches of AML/CFT requirements, the scope of AMLA’s enforcement powers will be limited. AMLA will nevertheless have an important regulatory impact and it will enhance the fight against cross-border financial crime by supporting the work of other bodies and agencies in the field.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by difficulties in social interaction and communication, repetitive behaviors, and restricted interests. Unfortunately, the underlying molecular mechanism behind ASD remains unknown. It has been reported that oxidative and nitrosative stress are strongly linked to ASD. We have recently found that nitric oxide (NO•) and its products play an important role in this disorder. One of the key proteins associated with NO• is thioredoxin (Trx). We hypothesize that the Trx system is altered in the Shank3 KO mouse model of autism, which may lead to a decreased activity of the nuclear factor erythroid 2-related factor 2 (Nrf2), resulting in oxidative stress, and thus, contributing to ASD-related phenotypes. To test this hypothesis, we conducted in vivo behavioral studies and used primary cortical neurons derived from the Shank3 KO mice and human SH-SY5Y cells with SHANK3 mutation. We showed significant changes in the levels and activity of Trx redox proteins in the Shank3 KO mice. A Trx1 inhibitor PX-12 decreased Trx1 and Nrf2 expression in wild-type mice, causing abnormal alterations in the levels of synaptic proteins and neurotransmission markers, and an elevation of nitrosative stress. Trx inhibition resulted in an ASD-like behavioral phenotype, similar to that of Shank3 KO mice. Taken together, our findings confirm the strong link between the Trx system and ASD pathology, including the increased oxidative/nitrosative stress, and synaptic and behavioral deficits. The results of this study may pave the way for identifying novel drug targets for ASD.
Metastatic Intestinal Adenocarcinoma: A Rare Case Involving the Mandible
Authors: Modak Baishakhi , Chandrashekar Chetana , Kudva Adarsh , Radhakrishnan Raghu
Published: September 2024

Background

Metastatic intestinal adenocarcinoma involving the mandible is rare, posing diagnostic challenges because of its unusual presentation.

Case presentation

A 55-year-old male presented with a rapidly growing mass in the right mandible, accompanied by facial asymmetry and vestibular obliteration. Histopathological examinations revealed features consistent with adenocarcinoma. Immunohistochemical analysis supported the diagnosis of intestinal adenocarcinoma, with subsequent metastasis confirmed by PET scan findings.

Diagnosis

The lesion was conclusively diagnosed as intestinal adenocarcinoma metastasizing to the mandible.

Management

The patient pursued treatment at a government facility, leading to a loss of follow-up.
The Principle of Total Evidence: Justification and Political Significance
Authors: Schurz Gerhard
Published: September 2024

The principle of total evidence says that one should conditionalize one’s degrees of belief on one’s total evidence. In the first part, I propose a justification of this principle in terms of its epistemic optimality. The justification is based on a proof of I. J. Good and embedded into a new account of epistemology based on optimality-justifications. In the second part, I discuss an apparent conflict between the principle of total evidence and the political demands of anti-discrimination. These demands require, for example, that information about the sex of the applicant for a job should not be included in the relevant evidence. I argue that if one assesses the applicant’s qualification in terms of those properties that are directly causally relevant for the job performance, then properties that are merely indirectly relevant, such as sex, race, or age, are screened off, i.e., become irrelevant. So, the apparent conflict disappears.
Good data relations key to Indigenous research sovereignty: A case study from Nunatsiavut

Published: September 2024

Although researchers are committed to Indigenous data sovereignty in principle, they fall short in returning data and results to communities in which or with whom they conduct their research. This results in a misalignment in benefits of research toward researchers and settler institutions and away from Indigenous communities. To explore this, we conducted a case study analyzing the rate researchers returned data to Nunatsiavut, an autonomous area claimed by Inuit of Labrador, Canada. We assessed the data return rate for all research approved by the Nunatsiavut Government Research Advisory Committee between 2011 and 2021. In two-thirds of projects, researchers did not return the data they had collected. Based on our results and their contextualization with researchers and Nunatsiavut Research Centre staff members, we compiled recommendations for researchers, academia, government bodies, funding bodies, and Indigenous research governance boards. These recommendations aim to facilitate data return, thus putting data sovereignty into practice.

Published: September 2024

In recent decades, the concentration of pharmaceutical residues and narcotics has increased in municipal wastewater. Decomposing these toxic organic chemicals is challenging and requires new techniques and advanced catalytic materials. Precursors of metal composites were prepared by calcining an aqueous suspension of natural clay–based kaolin with Mn and Cu, binding chemically the active metals to the aluminosilicate frame structure of the precursor. The specific surface area of Mn and Cu composite was 67 m2/g and 81 m2/g, respectively. The mechanical durability was determined in terms of compressive strength, and 3.3 MPa and 3.6 MPa were obtained, respectively. In the CWAO of pharmaceutical wastewater, Mn composite gave the highest conversions of 54% and 46% of the chemical oxygen demand (COD) and total organic carbon (TOC), respectively. Metal composites were mechanically and chemically highly durable, inducing only 1.2 wt.% and 1.4 wt.% mass loss. In CWAO, Mn and Cu composite increased the biodegradation of organic species in the wastewater by 65% and 75%, respectively.

Published: September 2024

This study aimed to determine changes in uterine artery Doppler parameters in unexplained recurrent pregnancy loss (URPL) and to explore serum markers possibly associated with them. This retrospective case–control study included 107 URPL women and 107 control women. The mean pulsatility index (PI), resistive index (RI), and systolic-to-diastolic values for uterine arteries in URPL women were significantly higher than those in the controls (P < 0.05). The cutoff values of PI and RI differentiating the women with URPL from the controls were confirmed by ROC and Youden’s index. Given a PI cutoff value of 2.6, the prevalence of URPL was significantly elevated in the high-PI group (74.58%) compared with that in the low-PI group (40.65%, P < 0.0001), with sensitivity and specificity of 63% and 69%, respectively. With an RI cutoff value of 0.86, the prevalence of URPL in the high-RI group (65.28%) was significantly elevated compared with that in the low-RI group (42.25%, P = 0.001), with sensitivity and specificity of 66% and 75%, respectively. The levels of serum D-dimers and anticardiolipin antibody (ACA)-IgM in URPL women were significantly higher than those in the controls. A positive correlation existed between the levels of ACA-IgM and uterine artery RI in URPL women (r = 0.43, P < 0.01). These results indicated that URPL women may be at a relatively high risk of a prothrombotic state, and the increased ACA-IgM deserves attention for its role in the elevated uterine artery Doppler parameters in URPL women.
