Self-regulated learning and video annotation in a high school acting classroom
Authors: Ellison Jessica Perry , Tang Hengtao 
Published: January 2025

AbstractThis research sought to answer the question about what students learnt from a self-regulated learning (SRL) video annotation tool in a hybrid secondary acting classroom. SRL is an important skill for students to self-direct their own learning processes. For the intervention, students engaged in a series of SRL activities through the video annotation tool, VideoAnt, for six weeks during the distance learning period. A convergent parallel mixed methods design was conducted. Quantitative data was collected using the International Thespian Society – Acting Rubric to assess students’ acting skills. Qualitative data was collected via semi-structured individual interviews. Quantitative findings demonstrated students gained proficiency in acting skills after using the video annotation tool in the acting classroom. Interview data about participants’ perceptions of the intervention were analyzed to triangulate quantitative findings. Implications of these findings for theatre/art educators and academics investing in SRL are discussed.
Problem-solving prior to instructional explanations when learning javelin throwing in primary school
Authors: Leukel Christian , Loibl Katharina 
Published: January 2025

AbstractLearning of motor skills in physical education classes occurs through different instructional approaches: via instructional explanations from the teacher (I), and via self-determined practice (problem-solving; PS). In our study, we explored whether the sequence of PS and I impacts performance enhancement among primary school children learning javelin throwing. Fifty 4th graders participated and were allocated to either I-PS or PS-I or PS-I with additional practice. Across groups, the children demonstrated improvements in executing movement features, yet there was no significant improvement in throwing distance. The temporal order of PS and I did not mediate these improvements. Additional practice did not lead to further improvements in performance. Our results contrast with earlier results in secondary school children in whom PS-I was more effective than I-PS Loibl & Leukel (2023). The lack of a significant advantage for PS-I over I-PS could stem from the primary children’s limited ability to develop declarative knowledge during PS that links to the content of I.
Strength enhancement of Ca(OH)2 activated ground granulated blast furnace slag-stabilized dredged sediments using Na2CO3
Authors: Ma Ning , Ye Hailong , Choi Clarence Edward , Zhang Jiaqi 
Published: January 2025

Abstract
The efficiency of alkali-activated ground granulated blast furnace slag in stabilizing dredged sediments with high water contents is suboptimal because the activators become diluted. To improve stabilization efficiency, additives such as nano-CaCO3 are proposed. However, some of the proposed additives may not be practical owing to their high costs. This study experimentally investigates the addition of Na2CO3 for the stabilization of dredged sediment with high water contents (i.e., 100%) using Ca(OH)2-activated slag. Experimental results show the optimal content of Na2CO3 to obtain the highest 28-day unconfined compressive strength of stabilized sediments is 0.2% gravimetrically. Below the optimal content, the strength increases with Na2CO3 content. Above the optimal content, a decrease in strength is observed. By examining the reaction products and microstructure of the stabilized dredged sediments, it is observed that the coupling mechanism of cation exchange and calcite precipitation promotes the development of finer capillary pores, leading to a reduction in interpore connectivity and lower structural heterogeneity of the fine capillary pores. Experimental evidence from this study broadens the practical applications of sustainable soil stabilization using additives.

Published: January 2025

Abstract
Purpose:
Structured abdominal examination is an essential part of the medical curriculum and surgical training, requiring a blend of theory and practice from trainees. Current training methods, however, often do not provide adequate engagement, fail to address individual learning needs or do not cover rare diseases.

Methods:
In this work, an application for structured Abdominal Examination Training using Augmented Reality (AETAR) is presented. Required theoretical knowledge is displayed step by step via virtual indicators directly on the associated body regions. Exercises facilitate building up the routine in performing the examination. AETAR was evaluated in an exploratory user study with medical students (n=12) and teaching surgeons (n=2).

Results:
Learning with AETAR was described as fun and beneficial. Usability (SUS=73) and rated suitability for teaching were promising. All students improved in a knowledge test and felt more confident with the abdominal examination. Shortcomings were identified in the area of interaction, especially in teaching examination-specific movements.

Conclusion:
AETAR represents a first approach to structured abdominal examination training using augmented reality. The application demonstrates the potential to improve educational outcomes for medical students and provides an important foundation for future research and development in digital medical education.
A Systematic Review of the Digital Divide Experienced by Migrant Women

Published: January 2025

AbstractDigital divide as an academic term captures the inequality involved in the access and usage of digital devices as well as real-life consequences of the imbalance. Concerning migrant women who suffer from the digital divide, there have been extensive studies focusing on the affordances and benefits of having digital access. The problematic side of digital divide and factors leading to such divide, however, are understudied. Therefore, a systematic review is conducted to investigate the digital divide items and factors from the existing literature. Studies (n = 19) were selected by searching through six social science databases of using the search words combination of “digital gap” and “digital divide,” “migrant,” “immigration” and “immigration,” and “female” and “women.” Findings suggest that concerning the access and utilization (level 1, 2 of digital divide), items such as poor network of the home country and factors such as patriarchal ICT culture hamper the access and usage of digital tools. Concerning the outcome of utilization (level 3 of digital divide), migrant service access and urban integration have been undermined. This review shows that digital divide experiences of migrant women have been understudied, and therefore we recommend that more empirical research, with multiple types of data and longitudinal design, in various immigrant-dense countries, should be conducted by adopting the theoretical lenses of lived experience and intersectionality, so that more voices of these women can be heard. In addition, needs assessment based on our identified digital divide factors should be conducted before the training programs for migrant women so as to more effectively bridge the digital divide.

AbstractExisting research has shown that emotional intelligence (EI) and teacher self-efficacy (TSE) play an important role in the work of in-service teachers. However, there is limited research on these variables and their associations among pre-service teachers. Also, the cultural context is expected to influence EI and TSE. Therefore, this study examined the associations between EI and TSE in two cultures, Finland and Greece. A comprehensive evaluation of EI was done by including both trait EI and ability EI measures. Data from primary education student teachers from Finland (N = 82) and Greece (N = 117) were collected online. The measures of EI and TSE exhibited full configural and metric measurement invariance and partial scalar and residual/strict measurement invariance across cultures. Finnish students had significantly higher scores on all EI variables than Greek students, whereas Greek students scored higher on self-efficacy for student engagement. Structural equation modelling showed that trait EI was moderately associated with one facet of ability EI, namely emotional management, but not with emotional understanding, implying that trait EI and ability EI can be considered as partially distinct constructs. A statistically significant positive association between trait EI and TSE was found in Finland, whereas a statistically significant negative association between ability EI and TSE was found in Greece. The findings have important implications for the models of trait and ability EI, for understanding the links between trait and ability EI and TSE during the critical phase of teacher education in the two cultural contexts studied, and for culturally informed teacher education.
Bronze Age monumental earthworks of the Friuli Plain (NE Italy): from LiDAR-based morphometric analysis to the reconstruction of settlement patterns and organization
Authors: Vinci Giacomo , Vanzani Federica 
Published: January 2025

Abstract
In this study, we use high-resolution data from airborne Light Detection and Ranging (LiDAR) acquisitions to comprehensively analyse late prehistoric earthwork structures in the alluvial plain of Friuli (NE Italy). By comparing LiDAR-derived models with direct topographic surveys of the structures carried out in the past we provide a detailed overview of the main characteristics of the structures. The new documentation, including Digital Terrain Models (DTMs), profiles and 3D models of the preserved structures, refines the topographic information collected by previous scholars and offers new insights into the development of sophisticated building techniques by Bronze Age communities. Additionally, by converting earthwork volumes into energetics and combining workforce investment analysis with other archaeological proxies—particularly site size and distribution—we have supported the analysis of settlement patterns and organization. Assuming 100 hypothetical full-time workers, the construction of burial mounds would have required from 1 week to 2 months; phase 3 monumental embankments at Sedegliano, Savalons, and Galleriano forts would have taken 4–10 months while 2.5–4 years at Udine. The Udine mound would have demanded up to 28 times the labour needed for other forts’ embankments, requiring approximately 11 years to complete and likely necessitating additional workforce from nearby settlements. This approach reveals the emergence of a defined hierarchical settlement system in the Friuli plain during the Recent Bronze Age, with the fort of Udine serving as a top-order settlement within a polity of smaller ones, akin to those recognized in the nearby regions of the Po Plain.

Published: January 2025

Abstract
In this paper, we analyze the performance of diffusion-based gas distribution in antiresonant hollow-core fiber-based gas absorption cells. Performed theoretical analysis was based on Fick’s second law using the OpenFOAM® software and finite volume method (FVM), followed by an experimental verification of the obtained simulations. The diffusion time was tested for a 1.25 m long fiber, with laser-micromachined microchannels. Full analysis of the correlation between the microchannel count, position, and separation on the rate at which the fiber-based gas cell was filled with the target gas was presented. Experimental results showed that with the proper microchannel configuration, the purely-diffusion-based gas exchange time in the 1.25 m fiber could be reduced from 6 h, down to 330 s. Obtained results correlated with the simulations, giving perspective for the development and implementation of novel miniaturized passively filled gas absorption cells for compact laser spectrometers.

Published: January 2025

Abstract
For cottontails (genus: Sylvilagus), suitable resting cover provides essential food and protection, leading to higher survival rates. As such, resting cover is a common target for management actions. In the Northeastern United States, efforts to conserve New England cottontails (Sylvilagus transitionalis) have focused on habitat restoration, yet their resting cover needs remain uncharacterized. Current management practices for resting cover borrow from guidelines from eastern cottontails (Sylvilagus floridanus), risking unintentionally favoring this non-native competitor. Furthermore, invasive plants alter the composition and structure of resting habitat potentially impacting species like cottontails that rely on shrubs for forage and protection. This study characterized daytime resting site use for New England and eastern cottontails and examined the impacts of resting site use on their survival. We specifically examined factors contributing to use of a common, potentially harmful invasive shrub, Japanese barberry (Berberis thunbergii) for both species. We showed both species used a diversity of resting cover types and use was similar between species. Cottontails relied heavily on vegetative cover, with dense vegetation used more frequently than less dense vegetative cover. Invasive/ non-native plant species were used as resting cover more than other cover types. Use of Japanese barberry appeared to be linked to the lack of other suitable native cover and was associated with reduced survival. We demonstrated that recommendations for eastern cottontail resting cover may suit New England cottontails and emphasize the complex tradeoffs inherent in invasive species management. Invasive shrub cover provides crucial resources in the absence of other cover but may also increase vulnerability of at-risk populations.
Mechanized HFMI for improved fatigue life in complex weld shapes

Published: January 2025

Abstract
This study investigates the implementation of mechanized high-frequency mechanical impact (HFMI) treatments to enhance the fatigue life of complex welded structures. Digital visual inspection and path planning are utilized through digital laser scanning system to automate the HFMI process for more complex weld shapes in S355 steel grade, such as circular weld seams, which are more challenging to treat consistently. The mechanized HFMI setup was calibrated to ensure precise alignment and consistent application of the HFMI tool along the weld toe line. Finite element analysis was used to simulate the HFMI process, focusing on the effects of multi-pass HFMI treatments and optimizing treatment parameters. The simulations identified fatigue initiation sites which were confirmed with the mechanized HFMI treated specimens. Fatigue testing of both as-welded and HFMI-treated samples was conducted, revealing significant improvements in fatigue strength for the HFMI-treated specimens, which is in line with IIW recommendations. The fatigue test results were also compared with previous testing of manually treated samples. It was concluded that the fatigue life scatter, expressed in log C (load capacity), resulted in a smaller standard deviation for the mechanically HFMI-treated samples than the manually treated samples. Geometric measurements from laser scanning post-HFMI treatment also indicated reduced scatter in weld toe radius and HFMI groove depth compared to manual treatments, demonstrating the robustness and consistency of the mechanized process.
A survey on point-of-interest recommendations leveraging heterogeneous data
Authors: Wang Zehui , Höpken Wolfram , Jannach Dietmar 
Published: January 2025

AbstractTourism is an important application domain for recommender systems. In this domain, recommender systems are for example tasked with providing personalized recommendations for transportation, accommodation, points-of-interest (POIs), etc. Among these tasks, in particular the problem of recommending POIs that are of likely interest to individual tourists has gained growing attention in recent years. Providing POI recommendations to tourists can however be especially challenging due to the variability of the user’s context. With the rapid development of the Web and today’s multitude of online services, vast amounts of data from various sources have become available, and these heterogeneous data represent a huge potential to better address the challenges of POI recommendation problems. In this work, we provide a survey of published research on the problem of POI recommendation between 2021 and 2023. The literature was surveyed to identify the information types, techniques and evaluation methods employed. Based on the analysis, it was observed that the current research tends to focus on a relatively narrow range of information types and there is a significant potential in improving POI recommendation by leveraging heterogeneous data. As the first information-centric survey on POI recommendation research, this study serves as a reference for researchers aiming to develop increasingly accurate, personalized and context-aware POI recommender systems.
SPH-FE coupling for the simulation of confined flow through permeable deformable membranes
Authors: Brugger Matthias , Traxl Roland , Lackner Roman 
Published: January 2025

AbstractWe present an extension of smoothed particle hydrodynamics (SPH) toward fluid flows involving the interaction with permeable deformable membranes. For this purpose, a coupled SPH-FE method based on a variational formulation of the immersed boundary (IB) method is developed. In the proposed method, weakly compressible SPH is used for the discretization of the fluid and a finite element (FE) method for thin structures for the discretization of the membrane. We consider confined flow in a two-dimensional fluid domain, with the membrane being represented as an elastic beam. Adopting the framework available for the IB method, the flux through the permeable membrane as described by Darcy’s law is considered. Finally, the proposed SPH-FE method is applied to two benchmark problems, i.e., the contraction of a circular membrane and the deformation of a membrane in a channel flow, comparing the numerical results with available analytical solutions.
Multidimensional integrable systems from contact geometry
Authors: Sergyeyev Artur 
Published: January 2025

AbstractUpon having presented a bird’s eye view of history of integrable systems, we give a brief review of certain recent advances in the longstanding problem of search for partial differential systems in four independent variables, often referred to as (3+1)-dimensional or 4D systems, that are integrable in the sense of soliton theory. Namely, we review a recent construction for a large new class of (3+1)-dimensional integrable systems with Lax pairs involving contact vector fields. This class contains inter alia two infinite families of such systems, thus establishing that there is significantly more integrable (3+1)-dimensional systems than it was believed for a long time. In fact, the construction under study yields (3+1)-dimensional integrable generalizations of many well-known dispersionless integrable (2+1)-dimensional systems like the dispersionless KP equation, as well as a first example of a (3+1)-dimensional integrable system with an algebraic, rather than rational, nonisospectral Lax pair. To demonstrate the versatility of the construction in question, we employ it here to produce novel integrable (3+1)-dimensional generalizations for the following (2+1)-dimensional integrable systems: dispersionless BKP, dispersionless asymmetric Nizhnik–Veselov–Novikov, dispersionless Gardner, and dispersionless modified KP equations, and the generalized Benney system.
Is Child Maltreatment Painful? An Exploration of Peritraumatic Pain in Child Maltreatment
Authors: Tsur Noga , Katz Carmit , Shemesh Nofar 
Published: January 2025

AbstractSubstantial findings point to the risk of chronic pain following child maltreatment (CM). However, a coherent explanation for the mechanisms underlying pain following CM is lacking. Although peritraumatic pain may encompass a significant role in these processes, a systematic quantification of peritraumatic pain in CM has never been conducted. This study was conducted to provide an initial exploration of peritraumatic pain characteristics in CM, and its links with CM characteristics, pain expression, and later posttraumatic outcomes. Two samples of adult CM survivors (N = 160 and N = 120, respectively) filled out self-report questionnaires assessing peritraumatic pain characteristics, CM characteristics, peritraumatic dissociation, and complex posttraumatic-stress symptoms (cPTSD). Peritraumatic pain was reported by 42.2% (76 participants) and 57% (69 participants) in Samples 1 and 2, respectively. While pain was most prevalent in physical abuse (90%), it was also prevalent in sexual (63%) and emotional abuse (37.5%; X2(3) = 14.65, p = .002). Peritraumatic pain was most prevalent when the perpetrator was a family member (X2(3) = 14.65, p = .002), longer CM duration (p < .001), and in fight-or-flight peritraumatic responses (X2(2) = 7.13, p = .028). Peritraumatic pain expression did not differ for CM type (p > .083), and most participants reported that the perpetrator ignored their pain (73.9%). Explicit and concealing expressions of pain were associated with later cPTSD symptoms (p < .047). The findings provide an initial understanding of peritraumatic pain characteristics and phenomenology, demonstrating that pain is a substantial constituent of CM experiences and potential posttraumatic outcomes.

Published: January 2025

AbstractAI-based optimal power management and online control of the storage system of the renewable energy microgrid in conjunction with the main grid that can respond instantaneously to any change in the load demand optimally and economically are the main target of this work. A novel online optimal control methodology depending on crossbreeding between the fuzzy logic and a nature-inspired technique has been proposed to determine the optimal time of carrying out the charging or discharging of the microgrid storage system and the required percentage of both of them in addition to the determination of the source of charging and the destination of discharging dynamically and economically at each time step to meet the varying of the load demand with minimum operating costs. A developed mathematical formula has been introduced to control the dynamic operation of the microgrid’s storage system. It has changed relying on the created fuzzy rules which provides outstanding accuracy for this complicated time-varying process. Furthermore, simultaneous optimal power management between the power generation as well as the storage system of the renewable microgrid and the main grid has been accomplished optimally and economically via a meta-heuristic optimizer named hunger games optimizer. The accuracy of the new methodology has been proved via a fair comparison with the previously published methods after implementing them on the same bases.
