Authors: Debener Aline , Job Ann-Katrin 
Published: December 2024

AbstractCollateral reports on psychopathology improve clinical care and research. Previous research showed moderate agreement between adults’ self- and collateral reports. Factors associated with discrepancies in different age groups, especially the crucial period of emerging adulthood, are yet to be investigated. We examined mother-child agreement and factors associated with discrepancies in N = 256 mother-child dyads with emerging adult children (M = 22.3 years) who participated in a longitudinal prevention study (18-year follow-up). Children completed self-report measures on psychopathology (Adult Behavior Checklist, ASR), current psychological distress, and two individual items regarding the mother-child relationship and frequency of contact. Mothers reported on their children’s psychopathology (Adult Behavior Checklist, ABCL) and their own psychological distress. Children and mothers completed a half-structured clinical interview on mental disorders. Agreement between ASR and ABCL was moderate to high (r = .48 to .53). Both reports significantly correlated with children’s diagnoses based on the clinical interview (r = .37 to .58). When children reported higher levels of psychopathology, higher levels of current psychological distress were associated with larger mother-child discrepancies. When mothers reported higher levels of child psychopathology, higher levels of maternal psychological distress, lower relationship quality, and higher frequency of contact were associated with larger discrepancies. Mother-child agreement in emerging adulthood is comparable to agreement in adolescence and adulthood. Factors associated with discrepancies differ for higher maternal- vs. self-reported psychopathology. Maternal psychological distress is more relevant for informant discrepancies than maternal mental disorder diagnoses. Longitudinal studies are needed to enhance the understanding of informant discrepancies.

Abstract
ACETEM (E472a) and CITREM (E472c) are fatty acid esters used as additives in the food industry to improve quality, stability and sensory properties of food products due to their emulsifying, stabilizing properties, and antioxidant and antimicrobial activities. Herein, we have explored their use as active plasticizers in one of the most used biobased polymers, polylactic acid (PLA). Initially, different CITREMs (LR10, SP70, RO and VEG) and ACETEM (SOFT-NSAFE), with a variety of compositions and physical states at room temperature, were characterized. The studied fatty acid esters demonstrate good thermal stability and moderate to good antioxidant properties. Subsequently, PLA films containing 10% of the tested fatty acid esters were prepared by melt extrusion and posterior compression molding. The obtained films were analyzed by different characterization techniques to evaluate their role as active plasticizers. Raman confocal microscopy showed that SOFT-NSAFE is homogeneously distributed in the PLA films, whereas CITREMs form microdomains due to their immiscibility with PLA. The incorporation of these plasticizers decreases the tensile strength, Young’s modulus and glass transition temperature. However, only CITREM-LR10 is able to significantly enhance the elongation at break of PLA up to 42%, due to the elongation and orientation of the microdomains along the cracks formed during the tensile test. Additionally, their incorporation provides antioxidant properties to the PLA films, being CITREM LR10, SP70 and SOFT-NSAFE that impart higher activity. In terms of antimicrobial activity, CITREM-LR10 showed effectiveness against S. aureus, while SOFT-NSAFE was active against L. innocua bacteria. These results open the possibility to use such CITREM and ACETEM food additives as plasticizers in films for a variety of applications such as active food packaging.

Published: December 2024

AbstractWhile formative assessment is a widely valued instructional approach to support meaningful learning, putting it into classroom practice remains a challenge, also because the time resources required may conflict with other goals. In a cluster-randomized controlled intervention study with 29 teachers and 604 students (mean age 15.6 years) at secondary school level, we examined the yield of formative assessment with regard to students’ conceptual understanding and quantitative problem-solving skills in physics. Ten teachers applied formative assessment (FA group) in a 14-lesson curriculum on kinematics after having undergone a training that focused on the implementation of multiple-choice concept questions together with monitoring tools, clicker sessions, and reflective lessons. In the frequent testing group (FT group), ten teachers had no training on formative assessment but implemented the same concept questions as those used in the FA group. Nine teachers taught kinematics in their traditional way (TT group). The results revealed that students in the FA group outperformed students in the other two groups in a test on conceptual understanding immediately after the intervention as well as 3 months later, whereas students from the FT group and the TT group did not differ. Importantly, a better conceptual understanding in the FA group was not at the expense of performance in quantitative problem solving, as students of this group better integrated both kinds of knowledge. Our study has shown that a short but well-structured formative assessment teacher training could unfold its potential in terms of students’ learning of challenging content.
AniClipart: Clipart Animation with Text-to-Video Priors

Published: December 2024

AbstractClipart, a pre-made graphic art form, offers a convenient and efficient way of illustrating visual content. Traditional workflows to convert static clipart images into motion sequences are laborious and time-consuming, involving numerous intricate steps like rigging, key animation and in-betweening. Recent advancements in text-to-video generation hold great potential in resolving this problem. Nevertheless, direct application of text-to-video generation models often struggles to retain the visual identity of clipart images or generate cartoon-style motions, resulting in unsatisfactory animation outcomes. In this paper, we introduce AniClipart, a system that transforms static clipart images into high-quality motion sequences guided by text-to-video priors. To generate cartoon-style and smooth motion, we first define Bézier curves over keypoints of the clipart image as a form of motion regularization. We then align the motion trajectories of the keypoints with the provided text prompt by optimizing the Video Score Distillation Sampling (VSDS) loss, which encodes adequate knowledge of natural motion within a pretrained text-to-video diffusion model. With a differentiable As-Rigid-As-Possible shape deformation algorithm, our method can be end-to-end optimized while maintaining deformation rigidity. Experimental results show that the proposed AniClipart consistently outperforms existing image-to-video generation models, in terms of text-video alignment, visual identity preservation, and motion consistency. Furthermore, we showcase the versatility of AniClipart by adapting it to generate a broader array of animation formats, such as layered animation, which allows topological changes.

Abstract

Introduction
Tree bacterial diseases are a threat in forestry due to their increasing incidence and severity. Understanding tree defence mechanisms requires evaluating metabolic changes arising during infection. Metabolite extraction affects the chemical diversity of the samples and, therefore, the biological relevance of the data. Metabolite extraction has been standardized for several biological models. However, little information is available regarding how it influences wood extract’s chemical diversity.

Objectives
This study aimed to develop a methodological approach to obtain extracts from different tree species with the highest reproducibility and chemical diversity possible, to ensure proper coverage of the trees’ metabolome.

Methods
A full factorial design was used to evaluate the effect of solvent type, extraction temperature and number of extraction cycles on the metabolic profile, chemical diversity and antibacterial activity of four tree species.

Results
Solvent, temperature and their interaction significantly affected the extracts’ chemical diversity, while the number of extraction cycles positively correlated with yield and antibacterial activity. Although 60% of the features were recovered in all the tested conditions, differences in the presence and abundance of specific chemical classes per tree were observed, including organooxygen compounds, prenol lipids, carboxylic acids, and flavonoids.

Conclusions
Each tree species has a unique metabolic profile, which means that no single protocol is universally effective. Extraction at 50 °C for three cycles using 80% methanol or chloroform/methanol/water showed the best results and is suggested for studying wood metabolome. These observations highlight the need to tailor extraction protocols to each tree species to ensure comprehensive metabolome coverage for metabolic profiling.

Abstract
This study aimed to investigate the expression, prognostic significance, methylation, and immune invasion levels of secreted frizzled-related proteins (SFRP1-5) in colorectal cancer (CRC). Additionally, the relationship between SFRP1/2 methylation and immune infiltration in CRC was explored. The expression of SFRP1-5 was analyzed using several databases, including GEO, TCGA, TIMER, STRING, and GEPIA. Molecular interactions with SFRPs were examined via Cytoscape software. Gene Ontology (GO) and Kyoto Encyclopedia of Genes, and Genomes (KEGG) pathway analyses were conducted using the DAVID database. Methylation levels of SFRP1/2 in CRC were assessed through methylation-specific PCR (MSP) and bisulfite sequencing PCR (BSP) experiments. Apoptosis and proliferation in CRC cells following the knockdown of SFRP1/2 expression were evaluated using flow cytometry and CCK-8 assays. The TISIDB database was used to analyze the relationship between SFRP1/2 methylation levels and immune infiltration. The expression of SFRP1, SFRP2, and SFRP5 was significantly lower in CRC patients, while SFRP4 expression was higher compared to that in healthy individuals. Elevated mRNA expression of SFRP2 was significantly associated with improved overall survival (OS), disease-specific survival, and progression-free intervals. SFRP1/2 expression was also linked to immune invasion, with higher levels correlating with increased immune infiltration. Both SFRP1 and SFRP2 showed hypermethylation in CRC. Knockdown of SFRP1/2 expression resulted in increased proliferation of CRC cells, and their methylation levels were inversely correlated with immune cell presence. The expression, methylation, and immune cell infiltration patterns of the SFRP family in CRC differed markedly from those in healthy individuals. These findings suggest that SFRPs may serve as potential therapeutic targets and key genes associated with immune cell infiltration in CRC.
The Impact of the Covid-19 Pandemic on Domestic Violence Injury: Insights from the National Crime Victimization Survey (NCVS)

Published: December 2024

AbstractThis study examined the consequences of domestic violence (DV) in light of the multiple changes to the lifestyles and routine activities of households during the Covid-19 pandemic using incident-level data from the National Crime Victimization Survey. Through logistic regressions, we first examined odds of injury among DV victims. We then examined odds of severe injury among DV victims who experienced injury. We compared the pre-pandemic odds of these injurious outcomes to these odds in two distinctive periods during the Covid-19 pandemic — March 2020-March 2021 and April 2021-December 2022. Study results suggest that the risk of both “any injury” and “severe injury” was higher between March 2020-March 2021 in comparison to the pre-pandemic period. Findings further suggest that the risk and severity of DV victims’ injury after April 2021 were not significantly different from the pre-pandemic era. Implications for policy and practice are discussed.
How does materialism influence interpersonal trust? A social projection perspective

Published: December 2024

Abstract
Past research has associated materialism with lower well-being. However, research on the effect of materialism on interpersonal trust and its underlying mechanism is limited. This research investigated how dispositional and situational materialism relate to interpersonal trust, as well as the mediation mechanism proposed based on a social projection account (social projection is a self-referential heuristic in which individuals assume others share similar mental experiences with them). Study 1 explored the associations of dispositional materialism with generalized and particularistic trust. The results showed that dispositional materialism could negatively predict generalized trust and particularistic trust in weak ties but could not predict particularistic trust in strong ties, and trustworthiness mediated the significant associations, aligning with the social projection principle. Study 2 examined the link between dispositional materialism and trust behavior in the trust game. The results showed that dispositional materialism negatively predicted trust behavior through the chain mediation effect of trustworthiness and social expectations about others’ trustworthiness, supporting our predictions based on the social projection account. Study 3 examined the causal relationship between materialism and interpersonal trust by activating participants’ materialistic orientation via situational cues (situational materialism). The results showed that situational materialism caused lower trust behavior, trustworthiness, and social expectations; however, situational materialism could not evoke the chain mediation effect proposed based on the social projection account. Our findings partially support the explanation of materialism-trust relation based on social projection and provide implications for trust promotion practice in the future.

Abstract
Objective
This study aimed to evaluate the physical performance of a Philips Gemini TOF PET/CT system using in-house developed sensitivity and scatter phantoms. The assessment was conducted in accordance with the NEMA NU2-2007 guidelines.

Methods
We developed in-house NEMA NU-2 Sensitivity (NU-2IndiSen) and Scatter (NU-2IndiSc) phantoms. These phantoms were evaluated through a series of tests: the alpha test, which included dimension comparison and radiation exposure comparison, and the beta test, which involved comparing NEMA NU-2 sensitivity and scatter fractions. In the dimension test, we compared the diameters of the NU-2IndiSen and NU-2IndiSc phantoms with those of the NU-2Sen and NU-2Sc phantoms. The radiation exposure tests involved comparing the surface radiation exposure from the NU-2IndiSen and NU-2IndiSc phantoms with that from the NU-2Sen and NU-2Sc phantoms. The beta tests assessed the sensitivity and scatter fraction of the Gemini TF 64 PET system using the NU-2IndiSen and NU-2IndiSc phantoms and compared these measurements with those obtained using the NU-2Sen and NU-2Sc phantoms.

Results
The dimension tests revealed no significant differences (p-value > 0.05) between the NU-2IndiSen and NU-2Sen phantoms, as well as between the NU-2IndiSc and NU-2Sc phantoms. Similarly, the radiation exposure tests showed no significant differences (p-value > 0.05) in surface radiation exposure between the NU-2IndiSen and NU-2Sen phantoms, and between the NU-2IndiSc and NU-2Sc phantoms. The average system sensitivity measured using the NU-2IndiSen and NU-2Sen NEMA phantoms were 6724 cps/MBq and 6748 cps/MBq, respectively, both exceeding the vendor's acceptance limit of > 6700 cps/MBq. Similarly, the scatter fraction, noise equivalent count rate (NECR), activity at which peak NECR is achieved, and maximum true count rate performance measured using the NU-2IndiSc and NU-2Sc phantoms were 25.9, 106.4 kcps, 18.5 kBq/ml, and 243.2 kcps, and 27.14, 106.03 kcps, 15.68 kBq/ml, and 263.2 kcps, respectively, all well within the vendor's prescribed limits.

Conclusion
The results of this study demonstrate that the in-house developed sensitivity and scatter phantoms accurately assess the performance of the Philips Gemini TOF PET/CT system. The obtained values for system sensitivity, scatter fraction, NECR, and true count rate are in excellent agreement with the vendor-specified limits, validating the use of these phantoms for routine quality assurance procedures.
The ecological system’s influence on physical activities of older adults: comparison between older men and women
Authors: Roh Su Yeon , Chang Ik Young 
Published: December 2024

Abstract
Background
Korea is expected to become a super-aged society by 2025. Research has shown that regular participation in physical activity has a positive impact on older adults’ health and reduces national health costs.

Aims
Drawing on Bronfenbrenner’s ecological model, this study examines ecological systems that influence physical activity in older men and women.

Method
The data analysis included information on 537 older adults aged 65 years and older residing in South Korea. The regression analysis identified differences in the ecological systems that influence physical activity in older adults by sex.

Results
By examining the ecological systems that affect physical activity in older men, this study found that the macrosystem affected the exosystem (p <.001) and microsystem (p <.001), the exosystem affected the mesosystem (p <.01), and the microsystem affected individuals (p <.001). In the case of older women, the macrosystem affected the exosystem (p <.001), microsystem (p <.001), and individuals (p <.01); the exosystem affected the microsystem (p <.01), and the microsystem affected individuals (p <.001).

Conclusions
The microsystem commonly affects the physical activity of older men and women, whereas the macrosystem only affects the physical activity of older women, suggesting that older men may experience limited macrosystem support in fostering their participation in physical activity. To address this disparity, the study highlights the need for targeted policies to enhance macrosystem support for older men, such as developing tailored physical activity programs that promote positive attitudes and accessible opportunities for participation.
Aqueous oxidation of coal-associated pyrite and standard pyrite mineral towards understanding the depyritization kinetics and acid formations
Authors: Mahanta Angana , Attry Binud , Saikia Binoy K. 
Published: December 2024

AbstractIn coal mining areas, the ambient atmospheric and aqueous oxidation of pyrite minerals (FeS2) associated with coal as well as the other accompanying strata is significant in understanding the extent of acid mine drainage (AMD), the cause of severe environmental pollution. Therefore, in this paper, the oxidation kinetics of the coal-associated pyrite (CAPy) present in a coal sample (TpHM1) has been studied via aqueous leaching depyritization experiments at variety of temperatures and time intervals without the incorporation of any oxidizer. The outcomes obtained are juxtaposed with the standard pyrite mineral (SPM) oxidation at the same experimental conditions. Also, the coal and SPM slurry residues and filtrates obtained after aqueous leaching at 25 °C and 90 °C for 0 h and 24 h, respectively, were extensively analyzed through high-resolution transmission electron microscopy (HR-TEM), Powder X-ray diffraction (P-XRD), and X-ray-photoelectron spectroscopy (XPS) for evaluation of the mineralogical composition and proportions of iron and sulfur components during progression of the oxidation reaction. Both the reactions obey pseudo first-order kinetics during pyrite (FeS2) oxidation but a significant difference in the experimentally found activation energies (Ea) and rate constants (k) values of oxidation kinetics of both CAPy and SPM may be attributed to the varied geochemical compositions of the coal associated pyrite (CAPy). The rate constant for CAPy is much greater than that of SPM implying a higher Ea around 10.838 kJ/mol for SPM as compared to 1.941 kJ/mol for CAPy. The CAPy in coal (TpHM1) is more susceptible to atmospheric oxidation than that of SPM, leading to the formation of acid mine drainage with lower pH. In this paper, the pH values on the basis of stoichiometric pyrite oxidation reaction were calculated and compared with the pH values obtained after aqueous leaching of CAPy to interpret the extent of acid formation and pyrite dissolution. Hence, with the assistance of the current study, further studies on the effects of mineral impurities, whereabouts of pyrite minerals in coal seams, the significance of compositional differences in the CAPy, the effect of metal oxides, and the role of alkalinity producing neutralizing agents of coal in the oxidative dissolution process of pyrite can be investigated.
