마음챙김이 초등학생의 불안에 미치는 영향

Objectives This study aim to explore the relationship between mindfulness and anxiety and the mediating effects of emotion regulation and worry on the relationship between mindfulness and anxiety. Methods The data were analyzed from 289 elementary school children in Seoul. Reliability analysis, technical sta-tistics, correlation analysis, and mediating effect analysis of each scale were conducted using the SPSS 18.0 and PROCESS Macro Model 4.2. Results Research results were as follows. First, the correlation between mindfulness and anxiety were significant, and regression analysis showed that mindfulness significantly predicted anxiety. Second, the mediating effect of emotion regulation and worry were significant in the relationship between mindfulness and anxiety. Conclusions This study was verified that children's mindfulness is a useful variable that directly affects anxiety re-duction and indirectly through emotional control and worry. It also provides useful information for making mindful-ness-based interventions. Considering the results that the indirect effect through worry was greater than the di-rect effect of mindfulness on anxiety, it suggests the need to include mindfulness activities on children's worry.

부모의 학습지원과 지지적 학교환경이 초등학생의 학습태도에 미치는 영향

Objectives The purposes of this study were to specify variables related to convergence competency, and to ana-lyze the structural relationships among them. The purposes of this study were to specify variables related to con-vergence competency, and to analyze the structural relationships among them. Methods In this study, 1,145 children who responded to all related variables in the 12th and 13th data of the Korean Children's Panel were used as data. The structural equation model was analyzed to understand the struc-tural relationship between each variable, and the direct and indirect effects were verified through this. In addition, the mediating effect was verified using bootstrapping. Results There was no significant relationship between parents' learning support and elementary school students' learning attitude, and there was a positive relationship between the supportive school environment and learning attitude. Grit showed a complete mediating effect in the effect of parental learning support on learning attitude, and Grit showed a partial mediating effect in the effect of supportive school environment on learning attitude. Conclusions Parents' learning support and supportive environment had a positive effect on Grit, which improved the learning attitude. This study is expected to help parents, who are interested in their children's learning, support direction and school environment by examining the influence and path of parents‘, school variables and grit that can positively affect learning attitudes.

Objectives The purpose of this study was to examine the indirect effects of creative self-efficacy on creative ach-ievement through emotion regulation strategies in dance majors, and to examine whether the effectiveness of emotion regulation strategies in mediating the relationship between creative self-efficacy and creative achieve-ment varies by dance experience level. Methods A total of 434 dance majors (46 males, 388 females, mean dance experience level: 7.35±3.79 years) re-sponded to questionnaires measuring creative self-efficacy, emotion regulation strategies, and creative achieve-ment, and the data were processed through mediation analysis and controlled mediation analysis using PROCESS version 4.0 for SPSS (Hayes, 2018). Results Creative self-efficacy positively influenced creative achievement directly as well as through emotion reg-ulation strategies. Furthermore, the effect of emotion regulation strategies on mediating the positive relationship between creative self-efficacy and creative achievement was stronger when the level of creative self-efficacy was high but the level of dance experience was low. We also found that the emotion regulation strategies that me-diate the positive relationship between creative self-efficacy and creative achievement are stronger when crea-tive self-efficacy is high but dance experience is low, and that the effect of creative self-efficacy on creative ach-ievement is stronger when college students with low creative self-efficacy have high dance experience. Conclusions The results suggest that it is important for college students majoring in dance to develop the ability to effectively manage their emotional experiences in order to be confident in their ability to effectively generate and perform creative ideas in order to solve problems and achieve goals during creative activities.

비대면 온라인 수업에서의 학습 참여도와 학생 만족도의 관계에 관한 실증적 연구

Objectives The purpose of this study is to empirically analyze the relationship between learning engagement and student satisfaction in a contactless online class environment. Methods The study employed regression analysis and text-based network analysis as research methods. Regression analysis was used to quantitatively measure the direct impact of learning engagement factors on stu-dent satisfaction. Text-based network analysis was used to explore the indirect effects on satisfaction by identify-ing information flow and centrality within the learning community. Results The analysis revealed a positive correlation between course completion rates and the frequency of the keyword ‘hard work’ in lecture comments, as well as the number of completed quiz submissions. However, the number of lectures and viewing time did not have a significant impact. The network analysis indicated that key-words such as ‘fun,’ ‘informative,’ ‘quiz,’ and ‘completion’ were central, suggesting that learner interaction is a crucial factor in satisfaction. Conclusions In conclusion, this study suggests that promoting interaction among learners and encouraging their active participation in course design can improve the efficiency and satisfaction of virtual classes. The empirical data provided here is expected to contribute to the improvement of educational technology.

Racial differences in links between perceived discrimination, depressive symptoms, and ambulatory working memory.

Perceived discrimination is associated with racial cognitive health disparities. Links between discrimination and cognitive performance, like working memory, in everyday settings (i.e. ambulatory performance) require investigation. Depressive symptoms may be a mechanism through which discrimination relates to ambulatory working memory. Discrimination, retrospective and momentary depressive symptoms/mood, and aggregated and momentary working memory performance among older Black and White adults were examined within the Einstein Aging Study. Racially stratified analyses revealed that discrimination did not relate to Black or White adults' ambulatory working memory. Among Black adults, however, more frequent discrimination was associated with greater retrospectively reported depressive symptoms, which related to more working memory errors across two weeks (indirect effect p < 0.05). This path was not significant among White adults. Links between discrimination and momentary working memory were not explained by momentary reports of depressed mood for Black or White adults. Depressive symptoms may play an important role in the link between discrimination and ambulatory working memory among Black adults across extended measurements, but not at the momentary level. Future research should address ambulatory cognition and momentary reports of discrimination and depression to better understand how to minimize cognitive health disparities associated with discrimination.

Early survival in Atlantic salmon is associated with parental genotypes at loci linked to timing of maturation.

Large effects loci often contain genes with critical developmental functions with potentially broad effects across life-stages. However, the life-stage-specific fitness consequences are rarely explored. In Atlantic salmon, variation in two large-effect loci, six6 and vgll3, is linked to age at maturity, and several physiological and behavioural traits in early life. By genotyping the progeny of wild Atlantic salmon that were planted into natural streams with nutrient manipulations, we tested if genetic variation in these loci is associated with survival in early life. We found that higher early life survival was linked to the genotype associated with late maturation in the vgll3, but with early maturation in the six6 locus. These effects were significant in high-nutrient, but not in in low-nutrient streams. The differences in early survival were not explained by additive genetic effects in the offspring generation, but by maternal genotypes in the six6 locus, and by both parents' genotypes in the vgll3 locus. Our results suggest that indirect genetic effects by large-effect loci can be significant determinants of offspring fitness. This study demonstrates an intriguing case of how large-effect loci can exhibit complex fitness associations across life stages in the wild and indicates that predicting evolutionary dynamics is difficult.

Social capital and consumer co-creation behaviors on tourism social media: the mediating role of psychological ownership

Purpose Consumer co-creation is a relational process through which consumers’ experiences, resources and knowledge are exchanged. This study aims to investigate the indirect effects of social capital on consumer co-creation behaviors, especially citizenship behaviors, through psychological ownership. Design/methodology/approach A survey was designed to measure social network, trust and shared vision, psychological ownership and citizenship behaviors; it was completed by 527 users of the Ctrip. Using data from the survey, a PLS model was constructed to depict the relationships between the key variables. Findings The results showed psychological ownership mediated the relationship between social capital and citizenship behaviors. Specifically, the chain-mediating effects of social capital dimensions (i.e. social network, shared vision and trust) on citizenship behaviors through psychological ownership were validated. Practical implications The rise of social media as a platform for consumer co-creation calls for a fundamental rethinking of traditional approaches to collaboration between companies and consumers. This study offers several suggestions for tourism companies to better engage with consumers on social media platforms. Originality/value This study extends current research by introducing social capital theory as a theoretical foundation for exploring tourism social media and determining the mediating role of psychological ownership between social capital and citizenship behaviors.

Target similarity and gender difference: Effects of servant leadership on supervisory commitment and supervisory citizenship behavior

PurposeThis study applies the target similarity model to examine the effects of servant leadership on supervisor commitment and supervisor citizenship behavior. The mediating role of supervisory commitment is explored to determine the relationship between servant leadership and supervisor citizenship behavior. The difference in supervisor gender is examined in the linkage between servant leadership and supervisory commitment.Design/methodology/approachThe data were collected through a survey of 478 salespeople in the retail industry. Structural equation modeling (SEM) techniques were used to verify the hypotheses of this study.FindingsThe findings showed significant support for the direct and indirect effects of servant leadership on supervisor commitment and supervisor citizenship behavior. Furthermore, the positive relationship between servant leadership and supervisory commitment was stronger among female supervisors than male supervisors.Originality/valueDue to the scarcity of studies conducted on the linkages of servant leadership, supervisory commitment and supervisory citizenship behavior, this study theoretically and empirically contributes to the leadership literature as it is the first study to investigate these direct and indirect relationships. Similarly, this study examined gender differences in servant leadership to fill the gap in the research field.

From genetic mosaicism to tumorigenesis through indirect genetic effects.

Genetic mosaicism has long been linked to aging, and several hypotheses have been proposed to explain the potential connections between mosaicism and susceptibility to cancer. It has been proposed that mosaicism may disrupt tissue homeostasis by affecting intercellular communications and releasing microenvironmental constraints within tissues. The underlying mechanisms driving these tissue-level influences remain unidentified, however. Here, we present an evolutionary perspective on the interplay between mosaicism and cancer, suggesting that the tissue-level impacts of genetic mosaicism can be attributed to Indirect Genetic Effects (IGEs). IGEs can increase the level of cellular stochasticity and phenotypic instability among adjacent cells, thereby elevating the risk of cancer development within the tissue. Moreover, as cells experience phenotypic changes in response to challenging microenvironmental conditions, these changes can initiate a cascade of nongenetic alterations, referred to as Indirect non-Genetic Effects (InGEs), which in turn catalyze IGEs among surrounding cells. We argue that incorporating both InGEs and IGEs into our understanding of the process of oncogenic transformation could trigger a major paradigm shift in cancer research with far-reaching implications for practical applications.

Indirect effects of plasma-activated water irrigation on Tetranychus urticae populations

AbstractPlasma-activated water (PAW) is receiving increased attention as a booster of seed germination and seedling vigor, and some studies have described use of PAW to manage crop pathogens. Here, we examined physicochemical properties of two PAWs (referred to as PAW 6.0 and 9.4 min with atmospheric plasma jet) and assessed “their indirect effects” (applied as supplementary irrigation) on host suitability of tomato plants (Solanum lycopersicum L.) to two-spotted spider mites (Tetranychus urticae Koch). Exposure of water to cold plasma significantly lowered pH and increased concentrations of H2O2, NO2−, and NO3−. Supplementary PAW irrigations elicited significant increases in leaf composition of several elements (N, P, K S, Ca, and Mg), leaf reflectance, plant size, and trichome densities (except non-glandular trichomes on the adaxial surface). Preference bioassays revealed significant avoidance of settling and reduced oviposition by two-spotted spider mites on leaf discs from PAW-irrigated plants compared to those from untreated control plants. Performance bioassays showed a significant decrease in two-spotted spider mite populations on PAW-irrigated plants. Results presented in this study provide comprehensive support to the hypothesis that indirect effects of supplementary PAW irrigation significantly reduce host plant suitability to two-spotted spider mites. PAW 6.0 may be slightly better than PAW 9.4, and this difference in performance is discussed in this study. Applications of PAW as supplementary irrigation are likely highly compatible with other IPM tactics and should be considered an innovative and sustainable component in twenty-first-century pest management.

Distance plus attention for binding affinity prediction

Protein-ligand binding affinity plays a pivotal role in drug development, particularly in identifying potential ligands for target disease-related proteins. Accurate affinity predictions can significantly reduce both the time and cost involved in drug development. However, highly precise affinity prediction remains a research challenge. A key to improve affinity prediction is to capture interactions between proteins and ligands effectively. Existing deep-learning-based computational approaches use 3D grids, 4D tensors, molecular graphs, or proximity-based adjacency matrices, which are either resource-intensive or do not directly represent potential interactions. In this paper, we propose atomic-level distance features and attention mechanisms to capture better specific protein-ligand interactions based on donor-acceptor relations, hydrophobicity, and π\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\pi $$\\end{document}-stacking atoms. We argue that distances encompass both short-range direct and long-range indirect interaction effects while attention mechanisms capture levels of interaction effects. On the very well-known CASF-2016 dataset, our proposed method, named Distance plus Attention for Affinity Prediction (DAAP), significantly outperforms existing methods by achieving Correlation Coefficient (R) 0.909, Root Mean Squared Error (RMSE) 0.987, Mean Absolute Error (MAE) 0.745, Standard Deviation (SD) 0.988, and Concordance Index (CI) 0.876. The proposed method also shows substantial improvement, around 2% to 37%, on five other benchmark datasets. The program and data are publicly available on the website https://gitlab.com/mahnewton/daap.Scientific Contribution StatementThis study innovatively introducesdistance-based features to predict protein-ligand binding affinity, capitalizing onunique molecular interactions. Furthermore, the incorporation of protein sequencefeatures of specific residues enhances the model’s proficiency in capturing intricatebinding patterns. The predictive capabilities are further strengthened through theuse of a deep learning architecture with attention mechanisms, and an ensembleapproach, averaging the outputs of five models, is implemented to ensure robustand reliable predictions.

The stomatal response to vapor pressure deficit drives the apparent temperature response of photosynthesis in tropical forests.

As temperature rises, net carbon uptake in tropical forests decreases, but the underlying mechanisms are not well understood. High temperatures can limit photosynthesis directly, for example by reducing biochemical capacity, or indirectly through rising vapor pressure deficit (VPD) causing stomatal closure. To explore the independent effects of temperature and VPD on photosynthesis we analyzed photosynthesis data from the upper canopies of two tropical forests in Panama with Generalized Additive Models. Stomatal conductance and photosynthesis consistently decreased with increasing VPD, and statistically accounting for VPD increased the optimum temperature of photosynthesis (Topt) of trees from a VPD-confounded apparent Topt of c. 30-31°C to a VPD-independent Topt of c. 33-36°C, while for lianas no VPD-independent Topt was reached within the measured temperature range. Trees and lianas exhibited similar temperature and VPD responses in both forests, despite 1500 mm difference in mean annual rainfall. Over ecologically relevant temperature ranges, photosynthesis in tropical forests is largely limited by indirect effects of warming, through changes in VPD, not by direct warming effects of photosynthetic biochemistry. Failing to account for VPD when determining Topt misattributes the underlying causal mechanism and thereby hinders the advancement of mechanistic understanding of global warming effects on tropical forest carbon dynamics.

Media exposure to climate change information and pro-environmental behavior: the role of climate change risk judgment

BackgroundThe aim of this study was to examine the relationships between exposure to climate change information in traditional and modern media, cognitive and emotional aspects of climate change risk judgment, and pro-environmental behavior (PEB).MethodA cross-sectional online study was conducted on a quota sample of 1,075 participants (51.9% women) aged 18–79 years. Participants self-reported their exposure to climate change-related information in traditional (e.g. television) and modern media (e.g. social networks), cognitive assessment of climate change risk, level of worry about climate change, and the frequency of PEB.ResultsStructural equation modeling showed a good fit for the parallel mediation model, involving cognitive risk judgment and worry as mediators between exposure to climate change information in traditional and modern media and PEB. Exposure to climate change information in traditional media had indirect effect on PEB through heightened worry, but not cognitive risk judgment. In contrast, exposure to climate change information in modern media had no indirect effect on PEB.ConclusionSince the link between exposure to climate change information in traditional media and PEB has been shown to be mediated by climate change worry, it is important to enhance the coverage of climate change in traditional media in Croatia, taking care to offer solutions to reduce possible negative impact on people’s well-being.

Predicting Students’ Genuine Learning Interest in Socio-Scientific Issues within an Engaged Learning Context

This study investigated the predictive effect of 11th grade Taiwanese students’ ( N = 878) self-assessed critical thinking, group participation self-efficacy, and active learning on their genuine learning interest (GLI) in socio-scientific issues (SSI). Results showed that active learning had a direct effect on GLI, while critical thinking and group participation self-efficacy had indirect effects on GLI as mediated by active learning. Critical thinking showed a significant direct effect on active learning, and a significant indirect effect on active learning that was mediated by group participation self-efficacy.

The mediation role of emotion regulation strategies on the relationship between mindfulness effects, psychological well-being and distress among youths: findings from a randomized controlled trial

AbstractThe Gaia program is a 12-week mindfulness intervention based on cultivating body, emotional, and ecological self-awareness, which has been shown to be effective in reducing children’s and adolescents’ internalizing problems, and improving psychological well-being, and psychological distress in early adolescents. To clarify the psychological processes underlying mindfulness effects on mental health among adolescents, the present study aimed to examine whether emotion regulation strategies (i.e., cognitive reappraisal and expressive suppression) may be considered as key processes linking the Gaia program effects to improvements in psychological distress and well-being. A total of 361 adolescents (mean age 14 years) were randomly assigned to one of two groups: the Gaia program (i.e., experimental group; N = 210) and waiting list (i.e., control group; N = 151). Measures were administered at three time points, approximately every three months: one week before treatment, one week after treatment, and three months after treatment. Using a structural equation model (SEM), we found that the Gaia Program had a positive and significant indirect effect on psychological well-being only via cognitive reappraisal as measured at follow-up [B = 0.181, 95% C.I. (0.012; 0.395)], whereas no significant indirect effects were found on psychological distress through cognitive reappraisal and expressive suppression. Findings from this study provide evidence of key emotional processes underlying the effects of a mindfulness intervention on positive but not negative psychological outcomes.

Model authenticity in learning mathematical experimentation: how students perceive and learn from scientist and peer models

AbstractThe implementation of video modeling examples of mathematical hands-on experimentation may provide students with authentic and, at the same time, not too cognitively overwhelming experiences. However, the effectiveness of video modeling examples can be influenced by different characteristics of the observed models. On the one hand, based on the model-observer similarity hypothesis, it is likely that the observation of peers is particularly conducive to learning. On the other hand, from an authentic learning perspective, the presence of experts is considered to constitute a core design element of authentic learning settings which may foster motivational and cognitive learning outcomes. Against the background of these contradictory assumptions, the present study investigates the effects of observing models with different degrees of authenticity on students’ perceived authenticity, their situational interest, and their knowledge acquisition. We conducted an experimental study with 105 10th graders who observed either peer or scientist models performing a mathematical hands-on experiment in a video recording. As expected, the results show that students perceived the scientist models as more authentic than the peer models. Furthermore, we found neither a direct effect of condition nor an indirect effect mediated by students’ perceived authenticity of the observed models on students’ situational interest and knowledge acquisition. With this study, we contribute to the literature on the conditions and effects of authentic learning.

Cost-effectiveness of PCV20 to Prevent Pneumococcal Disease in the Pediatric Population: A German Societal Perspective Analysis.

Since 2009, a pneumococcal conjugate vaccine (PCV) covering 13 serotypes (PCV13) has been included by Germany's Standing Committee on Vaccinations for infants, resulting in major reductions in pneumococcal disease (PD). Higher-valent vaccines may further reduce PD burden. This cost-effectiveness analysis compared 20-valent PCV (PCV20) under a 3+1 schedule with 15-valent PCV (PCV15) and PCV13, both under 2+1 schedule, in Germany's pediatric population. A Markov model with annual cycles over a 10-year time horizon was adapted to simulate the clinical and economic impact of pediatric vaccination with PCV20 versus lower-valent PCVs in Germany. The model used PCV13 clinical effectiveness and impact studies as well as PCV7 efficacy studies for vaccine direct and indirect effect estimates. Epidemiologic, utility, and medical cost inputs were obtained from published sources. Benefits and costs were discounted at 3% from a German societal perspective. Outcomes included PD cases, deaths, costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs). In the base case, PCV20 provided greater health benefits than PCV13, averting more cases of invasive pneumococcal disease (IPD; 15,301), hospitalized and non-hospitalized pneumonia (460,197 and 472,365, respectively), otitis media (531,634), and 59,265 deaths over 10 years. This resulted in 904,854 additional QALYs and a total cost saving of €2,393,263,611, making PCV20 a dominant strategy compared with PCV13. Compared to PCV15, PCV20 was estimated to avert an additional 11,334 IPD, 704,948 pneumonia, and 441,643 otitis media cases, as well as 41,596 deaths. PCV20 was associated with a higher QALY gain and lower cost (i.e., dominance) compared with PCV15. The robustness of the results was confirmed through scenario analyses as well as deterministic and probabilistic sensitivity analyses. PCV20 3+1 dominated both PCV13 2+1 and PCV15 2+1 over 10 years. Replacing lower-valent PCVs with PCV20 would result in greater clinical and economic benefits, given PCV20's broader serotype coverage.

The Influence of Culinary Diversity and Tourism Events on Tourist Expenditures (Study in Central Lombok Regency with Destination Image as Intervening Variable)

This research investigates the interplay between culinary diversity, tourism events, destination image, and tourist expenditures in Central Lombok Regency, Indonesia. A quantitative approach utilizing Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed to analyze data gathered from domestic and international tourists. Hypothesis testing revealed significant positive relationships between culinary diversity and tourist expenditures, tourism events and tourist expenditures, culinary diversity and destination image, tourism events and destination image, as well as indirect effects through destination image on tourist expenditures. The result highlights the economic importance of diverse culinary experiences and engaging events in driving tourism revenue, shaping destination image perceptions, and influencing tourists' spending behaviors. The study underscores the need for integrated destination management strategies to leverage Central Lombok's cultural and gastronomic assets for sustainable tourism development.

The role of culture and semantic organization in working memory updating

ABSTRACT Westerners tend to relate items in a categorical manner, whereas Easterners focus more on functional relationships. The present study extended research on semantic organization in long-term memory to working memory. First, Americans’ and Turks’ preferences for categorical versus functional relationships were tested. Second, working memory interference was assessed using a 2-back working memory paradigm in which lure items were categorically and functionally related to targets. Next, a mediation model tested direct effects of culture and semantic organization on working memory task behaviour, and the indirect effect, whether semantic organization mediated the relationship between culture and working memory interference. Whereas Americans had slower response times to correctly rejecting functional lures compared to categorical lures, conditions did not differ for Turks. However, semantic organization did not mediate cultural difference in working memory interference. Across cultures, there was evidence that semantic organization affected working memory errors, with individuals who endorsed categorical more than functional pairings committing more categorical than functional errors on the 2-back task. Results align with prior research suggesting individual differences in use of different types of semantic relationships, and further that literature by indicating effects on interference in working memory. However, these individual differences may not be culture-dependent.

G-formula for observational studies under stratified interference, with application to bed net use on malaria.

Assessing population-level effects of vaccines and other infectious disease prevention measures is important to the field of public health. In infectious disease studies, one person's treatment may affect another individual's outcome, that is, there may be interference between units. For example, the use of bed nets to prevent malaria by one individual may have an indirect effect on other individuals living in close proximity. In some settings, individuals may form groups or clusters where interference only occurs within groups, that is, there is partial interference. Inverse probability weighted estimators have previously been developed for observational studies with partial interference. Unfortunately, these estimators are not well suited for studies with large clusters. Therefore, in this paper, the parametric g-formula is extended to allow for partial interference. G-formula estimators are proposed for overall effects, effects when treated, and effects when untreated. The proposed estimators can accommodate large clusters and do not suffer from the g-null paradox that may occur in the absence of interference. The large sample properties of the proposed estimators are derived assuming no unmeasured confounders and that the partial interference takes a particular form (referred to as 'weak stratified interference'). Simulation studies are presented demonstrating the finite-sample performance of the proposed estimators. The Demographic and Health Survey from the Democratic Republic of the Congo is then analyzed using the proposed g-formula estimators to assess the effects of bed net use on malaria.
