Published: February 2025

Abstract
Wildlife feeding and nutrition are key drivers of several demographic parameters, such as breeding success and survival, influencing long-term population viability. To comply with the diet requirements that ensure offspring survival, parents adapt their forage strategies to the environmental conditions and resource availability. This is especially important for central-place foragers like raptors, where prey availability in the surroundings of nest and livestock carcasses significantly impact both foraging efforts and breeding success. Here we take advantage of 20 years extensive monitoring (2001–2020) of the Canarian Egyptian vulture (Neophron percnopterus majorensis) on the Fuerteventura Island (Canary Islands, Spain) to assess (1) what factors drive vulture diet diversity and, (2) how the number of livestock and diet diversity coupled together with environmental conditions affect breeding success and, ultimately, the conservation of vulture populations. We identified 3,787 prey items belonging to 37 different species. Diet diversity was positively related to the number of wild prey and to low livestock grazing pressure periods. Breeding success was positively related to the number of wild prey, low herbivory pressure and, to a lesser extent, to diet diversity. These results demonstrate the importance of wild prey on Canarian Egyptian vulture’s diet, albeit livestock carcasses are the most abundant feeding resource. We argue that livestock have controversial conservation implications for this species because it provides a stable feeding resource, but, in turn, is one of the major ecosystem disruptors. Overgrazing by livestock can negatively affect wild primary consumers, which are essential for this endemic vulture population.

Published: February 2025

Abstract
Health-threatening underweight and poor growth is a frequent consequence of Avoidant restrictive food intake disorder (ARFID) and should be a priority for treatment in children and adolescents (young people, YP). Coexisting autism is more prevalent in YP with ARFID than in YP with other eating disorders. Treatment studies are still sparse for ARFID, and it is not known whether treatment response is lower in those with coexisting autism, as it is documented in other eating disorders. In this study we examined if family-based treatment for ARFID (FBT-ARFID) was associated with weight gain in underweight young people (YP) with ARFID and if coexisting autism affected weight gain. A clinical naturalistic prospective case series of 33 YP aged 6.3–18 years with ARFID presentations and underweight were offered a manualized FBT-ARFID with weight monitoring. We examined changes in body weight between start and end of treatment in those with and without diagnosed coexisting autism. The majority of participants (N = 26, 79%) had a weight gain between 1 and 15 kg, whereas 7 YP (21%) had a stable body weight between start and end of treatment (differences between − 0.6 kg and + 0.9 kg). At the group level, weight gain was statistically significant between start and end (Median = 3.9 kg (4.0, -0.6 -15.1) z = 4.491, p <.001). There was no significant difference in weight gain between participants with (N = 14, 42%) and without (N = 19, 58%) coexisting autism. Participants had a significant weight gain at the group level, suggesting that FBT-ARFID is associated with weight gain in the majority of underweight ARFID patients, both with and without coexisting autism. However, a subgroup may need additional interventions in order to secure weight rehabilitation.

Abstract
Endemic species are often at greater risk of extinction and therefore should be a high priority for conservation. Lord Howe Island is a biodiversity hotspot with numerous endemic species, including the iconic McCulloch’s anemonefish, Amphiprion mccullochi. This study investigates the genetic relationship between A. mccullochi and its closely related sister species, Amphiprion akindynos, to clarify whether these species are genetically distinct; assess historical and contemporary gene flow; and evaluate genomic diversity and effective population sizes. We sampled across the range distribution of both species and used genome-wide Single Nucleotide Polymorphism (SNP) data. Clustering analyses showed a clear partition between A. mccullochi and A. akindynos with no evidence of recent gene flow, while demographic modelling indicated historical unidirectional gene flow from A. akindynos to A. mccullochi. Genetic diversity metrics revealed lower nucleotide diversity (π) and effective population size (Ne) in A. mccullochi, reflecting its restricted distribution and suggesting heightened extinction risk. Our findings provide genomic context and baseline information for the conservation management of A. mccullochi. Given the current trend of declining A. mccullochi populations, our findings suggest that conservation efforts should emphasize preserving population sizes and genetic diversity and ultimately preventing extinction of this endemic reef fish.

Published: February 2025

Abstract
The present study introduces a circumplex model of study well-being as an application of occupational well-being research to a higher education context. Accordingly, the first aim was to identify what kind of study well-being profiles (SWP), representing different levels and combinations of study engagement, burnout, satisfaction, holism, and boredom; there are among university students and how stable the SWPs are during the academic school year. The second aim was to investigate how the identified SWPs are related to students’ recovery strategies and perceived academic performance. A total of 812 Finnish university students filled in an e-survey at the end of the fall semester (T1) and 316 of them did it again at the end of the spring semester (T2). Latent transition analysis revealed altogether four SWPs (at T1/T2): Moderate (44/42%), Engaged-Satisfied (26/25%), Engaged-Holists (17/17%) and Bored-Burned out (13/16%). Latent transition analysis showed that the detected SWPs were highly stable: 86% of the participants remained in their SWP across the academic year. However, where transitions occurred from one profile to another, they were mainly from better to worse. Furthermore, the results showed that students from Moderate or Engaged-Satisfied profiles reported more beneficial recovery strategies and experienced better academic performance than students from Engaged-Holists or Bored-Burned out profiles. In conclusion, this study highlights that study engagement and holism can co-exist, particularly in performance-oriented, success-tracking, and evaluative environments such as academia, without necessarily advancing academic performance and posing a threat to recovery from study-related stress.
Returns from rare coins: a machine learning approach
Authors: Sagarra Marti , Vici Laura , Zanola Roberto 
Published: February 2025

Abstract
Despite the existence of several studies on collectibles, the rare coin market is still underexplored. This paper examines this market with a sample of 5553 Spanish columnarios (1732–1772) auctioned from 1992 to 2021, investigating the key factors influencing auction prices using a dataset with an extensive number of covariates. Traditional hedonic models face challenges with large datasets, including multicollinearity, overfitting, and parameter complexity, which compromise clear and reliable interpretation. To address these limitations, this study employs the cross-fit partialing-out LASSO regression to select key explanatory variables, resulting in unbiased estimates and insights for investors and researchers. An interrupted time series analysis is subsequently conducted to compare indices derived from the traditional and LASSO hedonic methods. Findings confirm that LASSO approach outperforms the traditional hedonic regression method in terms of estimation accuracy.

Published: February 2025

Abstract
Traditional human anatomy teaching relies on face-to-face models, although new methodologies based on virtual platforms can enhance autonomous learning. However, the specific type of online tools preferred by the students remains unclear. This study compared student engagement with two teaching tools: (1) online unidirectional lessons and (2) an interactive Instagram profile, @eldeanato. Both tools incorporated new anatomical illustrations and detailed dissection photographs. The Instagram profile included questionnaires via the Instagram stories quiz sticker. Students’ satisfaction was assessed by means of online surveys. Engagement with each of the interventions was evaluated using objective measures of web analytics: percentages of interaction with the questionnaires on Instagram and adding Google Analytics tools to the online lessons’ website code. Student satisfaction with both types of material was high, but the participative material had much higher engagement scores. The Instagram profile allowed continuous participation, with increasing followers and interaction levels. Our results show the importance of objective engagement measurements to evaluate the success of innovative teaching interventions. In order to increase student adherence, teaching interventions should be participative and integrated with popular social networks, like Instagram, even though this is a field that could be seen as estranged from academic teaching.

Published: February 2025

Abstract
The construction of carbon nanocoil (CNC)-based chiral-dielectric-magnetic trinity composites is considered as a promising approach to achieve excellent low-frequency microwave absorption. However, it is still challenging to further enhance the low frequency microwave absorption and elucidate the related loss mechanisms. Herein, the chiral CNCs are first synthesized on a three-dimensional (3D) carbon foam and then combined with the FeNi/NiFe2O4 nanoparticles to form a novel chiral-dielectric-magnetic trinity foam. The 3D porous CNC-carbon foam network provides excellent impedance matching and strong conduction loss. The formation of the FeNi-carbon interfaces induces interfacial polarization loss, which is confirmed by the density functional theory calculations. Further permeability analysis and the micromagnetic simulation indicate that the nanoscale chiral magnetic heterostructures achieve magnetic pinning and coupling effects, which enhance the magnetic anisotropy and magnetic loss capability. Owing to the synergistic effect between dielectricity, chirality, and magnetism, the trinity composite foam exhibits excellent microwave absorption performance with an ultrabroad effective absorption bandwidth (EAB) of 14 GHz and a minimum reflection of loss less than − 50 dB. More importantly, the C-band EAB of the foam is extended to 4 GHz, achieving the full C-band coverage. This study provides further guidelines for the microstructure design of the chiral-dielectric-magnetic trinity composites to achieve broadband microwave absorption.

Abstract
One of the significant technological challenges in safeguarding electronic devices pertains to the modulation of electromagnetic (EM) wave jamming and the recycling of defensive shields. The synergistic effect of heterodimensional materials can effectively enable the manipulation of EM waves by altering the nanostructure. Here we propose a novel approach for upcycling by-products of silver nanowires that can fabricate shape-tunable aerogels which enable the modulation of its interaction with microwaves by heterodimensional structure of by-products. By-product heterodimensionality was used to design EM-wave-jamming-dissipation structures and therefore two typical tunable aerogel forms were studied. The first tunable form was aerogel film, which shielded EM interference (EMI shielding effectiveness (EMI SE) > 89 dB) and the second tunable form was foam, which performed dual EM functions (SE > 30 dB& reflective loss (RL) < -35 dB, effective absorption bandwidth (EAB) > 6.7 GHz). We show that secondary recycled aerogels retain nearly all of their EM protection properties, making this type of closed-loop cycle an appealing option. Our findings pave the way for the development of adaptive EM functions with nanoscale regulation in a green and closed-loop cycle, and they shed light on the fundamental understanding of microwave interactions with heterodimensional structures.

Published: February 2025

Abstract

Purpose
Development of consensus-based recommendations on core and optimal elements of orthogeriatric hip-fracture care.

Methods
An online Delphi survey was performed in the Netherlands. A total of 72 statements were derived from a framework encompassing all phases of care for older patients with a hip fracture. These statements were presented to the panelists in two rounds to identify elements for minimal and optimal orthogeriatric care. Panelists included professionals with experience in hip-fracture care and patient representatives. The level of agreement was measured using a 5-point Likert scale. Consensus was considered if > 75% of the panelists agreed or disagreed.

Results
Ninety-two persons were invited to participate in the survey; 63 participated in the first round and 55 in the second round. One statement was added in the second round. Most participants had a background in geriatrics (36% in the second round) or trauma surgery/orthopaedics (20% in the second round). Consensus was reached on 48 statements for minimal orthogeriatric care and 60 statements for optimal orthogeriatric care.

Conclusion
This study supports previously established recommendations for older adults with hip fractures. In addition, it offers practical recommendations for implementation of orthogeriatric care regarding both core and optimal care elements for hospitals at every different level of maturity and at every step in the care process. This may decrease the intra- and inter-hospital variability of clinical management of hip-fracture patients. Organizational and logistical elements present a barrier to overcoming the gap between the current practice and the optimal situation.

Published: February 2025

Abstract
Incels (involuntary celibates) are part of a broader misogynistic culture known as the manosphere. Some communities within the manosphere, including incels, promote gender-based violence through misogynistic rhetoric and ideology. Incels are men who struggle to form romantic relationships and thus seek solace in online forums to find a sense of purpose and community. The community is organised around an ideology and a hierarchical classification of members. This paper presents a computational linguistic analysis of the utterances made within the community. We analyse the linguistic patterns of six different ranks of users: paragons, high-rank users, low-rank users, greycels, banned users, and self-banned/deleted users. We conducted an analysis of the sentiments expressed between ranks and of the affective attitude of posters when discussing a variety of topics. We then we analysed linguistic features, also conditioned on the rank of the poster. These analyses reveal qualitative differences between users of different ranks in how they express themselves and their sentiments. Finally, we trained models based on the linguistic features of users’ posts and show that already based on this information it is possible to predict the rank of users. Overall, our results indicate that the incel community has developed distinctive linguistic patterns to disseminate their ideology and that these linguistic patterns vary according to the rank of an incel within the community. This methodology offers a robust framework for studying similar echo chamber-like communities.

Abstract
The enhancement of the flame retardancy of polydicyclopentadiene (PDCPD) while maintaining its excellent mechanical properties has long been an important and critical technical challenge for many years. In this contribution, we designed and synthesized a new flame-retardant monomer containing double norbornene groups (NB-PDP) which can undergo the frontal ring-opening metathesis polymerization (FROMP) with dicyclopentadiene (DCPD) and 5-dicyclopentadiene-2-carboxylic acid (NB-COOH). Through the formulation optimization, the flame retardancy and mechanical properties of the copolymers could be easily regulated. To investigate the influencing mechanism of the NB-PDP and NB-COOH on the properties of the copolymers, the thermodynamics and kinetics of the FROMP, as well as the micro-structures, mechanical properties, and flame-retardant performance of the PDCPD/NB-PDP/NB-COOH copolymers were systematically studied. The findings suggest that the integration of NB-PDP and NB-COOH resulted in a diverse array of physical and chemical cross-linking networks within the system. Consequently, the tensile strength of the copolymers reached a maximum of 63.1 MPa and the elongation at break achieved up to 28.5%, representing the increases of 43.0% and 154.0% compared to that of PDCPD without any modification, respectively. It is worth mentioning that except the flame-retardant NB-PDP, NB-COOH could also serve as the carbon source to enhance the char formation and further improve the flame-retardant properties, such as the limiting oxygen index (LOI), peak heat release rate (PHRR), total heat release (THR), and total smoke production (TSP). These phenomena indicate that the material exhibits excellent mechanical properties and conspicuous flame retardancy. This work provided an efficient method for the preparation of the intrinsically flame-retardant PDCPD materials and a new strategy for the constructing of the thermosetting materials with excellent comprehensive performance.
Exploring Adolescents’ Ratings of Social Profiles: The Impact of Eye Gaze
Authors: Anderson Ashley N. , Rapp John T. , Bush Helena 
Published: February 2025

Abstract
Understanding the impact of eye gaze on social interactions may mitigate some risks for adolescents who are either currently justice-involved or at risk of contacting the justice system. At present, there are no universally accepted assessments for determining age-appropriate levels of eye gaze for adolescents during social interactions. One way to evaluate an individual’s sensitivity to eye gaze is to determine if they can detect different levels of eye gaze in other people. Bush et al. Developmental Neurorehabilitation, 25, 263–273, (2021) created three videos (profiles) of an actor displaying three different levels of eye gaze (directed toward an off-screen interviewer) and then asked college students to rate the actor in the three profiles using six statements. Bush et al. found college students provided the most favorable ratings for the profile with a high, but not the highest, level of eye gaze. This study used the same three video profiles of a speaker and six statements to assess ratings by two groups: non-justice-involved adolescents and justice-involved adolescents. Results indicate both groups rated the three speaker profiles differently for some statements. In particular, both groups rated the low eye gaze profile less favorably than the other two profiles. Analyses also revealed (1) non-justice-involved adolescents rated the high eye gaze profile as less attentive but more likely to get an important job than the justice-involved group and (2) justice-involved adolescents rated the “socially valid” profile as less likely to have friends than non-justice-involved adolescents. Implications and next steps are discussed.

Abstract
Nowadays, the research in the field of building materials revolves around the basic principles of sustainability, environmental protection, circular economy and proper management of natural and financial resources. In this context, the current study aimed to implement several biomaterials of diverse species and geometry into cement mortar mixtures and to evaluate their physical, mechanical and hydrothermal properties. Thus, black pine wood and bark powder, pellet crumb and agro-pasture and hemp fibers were incorporated at 1.5% v/v addition rate in cement mortars. After 28 hardening days, all bio-enhanced mortar samples presented advanced flexural strength and decreased specific gravity and thermal conductivity records in relation to the reference-unreinforced case. Furthermore, the powder-crumb like biomaterials seemed to perform as fillers reducing the porosity and capillary absorption values of the specimens compared to the reference composition. From the analysis it seems that biomaterials could provide low cost and eco-friendly reinforcement solutions in the construction sector.
