The purpose of this paper is to examine the development of a curriculum in Japan to foster the agency(OECD Student Agency)necessary for children living in the future,as outlined in the OECD Education2030 Project,and the role of teachers who implement this curriculum.Therefore,I aim to achieve this goal by taking an overview of educational thought,educational systems and history,and examining several initiatives in the OECD Project and the situation of a Japanese high school that practices science and mathematics education.As a result of analyzing previous research and the narratives obtained from interviews with Teacher A(pseudonym)of a certain F High School(pseudonym),it was found that school education should not simply teach subjects,but should aim to enable student to help student exercise agency in the future.It was suggested that it is not necessary to add content to the curriculum,but rather to prepare to provide students with competencies that will enable them to use the content in various contexts,situations,and circumstances,suggesting that in order to discover such important competencies,teachers and other related parties are required to implement curricula that allow students to slowly and carefully explore the competencies surrounding the content,and to conceive and build curricula that include both hidden and intended curriculum that allows student to reflect on the curriculum they have achieved. 展开更多

The construction of early childhood curriculum resources serves as a vital vehicle and precondition for the implementation of collective teaching activities in kindergartens.However,traditional curriculum resources based on graphic language or the linguistic descriptions of early childhood educators often fail to provide children with an immersive experience during collective teaching activities,leading to a lack of initiative and interest in learning.This paper discusses the methods for building a kindergarten curriculum resource library and,based on this foundation,employs virtual reality technology for three-dimensional modeling of the library to enrich the curriculum resources in kindergartens.Furthermore,this paper proposes to train early childhood educators in virtual reality technology to enhance their abilities to operate and utilize virtual reality equipment,which can emphasize the children’s central role in the learning process,better achieve educational goals,and improve teaching outcomes. 展开更多

Background:Theory of Mind(ToM)and empathy are crucial cognitive and emotional capacities that influence social interactions.While their role in promoting prosocial behavior has been established,the potential moderating effect of mindfulness on this relationship remains unexplored.Understanding these complex interactions is vital for developing effective interventions to foster prosocial behavior among college students.This study examines the influence of ToM on college students’prosocial behavior and explores the moderating role of mindfulness in this relationship.Methods:A mixed-methods approach combining questionnaires and experimental design was employed.Study 1:A survey of 759 college students(mean age 22.03 years;477 females)was conducted using the ToM Scale,Interpersonal Reactivity Index,Prosocial Behavior Tendency Scale,and Mindfulness Awareness Scale.Data were analyzed using correlation and moderated mediation analyses.Study 2:An 8-week mindfulness attention training program was implemented for the intervention group and compared with a control group.Mindfulness training served as a moderating variable to validate Model 59 from Study 1.Results:1.Study 1 found:(a)ToM was significantly positively correlated with prosocial behavior(r=0.31,p<0.01).(b)Empathy partially mediated the relationship between ToM and prosocial behavior(β=0.10,p<0.001,95%CI[0.06,0.14]).(c)Mindfulness negatively moderated the direct path between ToM and three dimensions of prosocial behavior,as well as the indirect path between empathy and kin altruism and reciprocal altruism.Specifically,high levels of mindfulness weakened the direct impact of ToM on prosocial behavior.High levels of mindfulness also weakened the indirect influence of ToM on prosocial behavior through empathy.2.Study 2 results showed:(a)The intervention group had significantly higher levels of trait mindfulness compared to the control group(t=2.56,p<0.05).(b)The validity of the moderated mediation model 59 from Study 1 was verified.Conclusion:While ToM and empathy play crucial roles in fostering prosocial behavior,mindfulness exhibits a more complex influence than anticipated,potentially inhibiting prosocial behavior under certain circumstances.These findings offer novel insights into the psychological mechanisms underlying prosocial behavior and underscore the importance of considering multiple interacting factors in its promotion. 展开更多

Because of factors such as energy and time one invests in an object,the stronger the connection,value,and reluc-tance to lose said object individual will have.Hoarding behavior arises when individuals incorporate a strong attachment with themselves to an object.The purpose of this study is to examine the effect of self-investment on hoarding tendency and the roles of possession-self link and liking level in this connection.A hypothetical model of the relationship between self-investment,possession-self link,liking level,and hoarding tendency was tested.A convenience sampling method was used to survey 450 college students in Yunnan Province on either a paper-based or online self-report scale.The data were collected using self-investment,possession-self link,and liking level questionnaires,as well as the Saving Inventory Revised.Results showed positive relationship between the study variables,ranging from 0.37 to 0.87.College students’self-investment had a direct positive pre-dictive effect on hoarding tendency;self-investment,in turn,indirectly predicted hoarding tendency through the mediating effect of possession-self link;and individual liking level of items had a moderating effect for self-invest-ment on the possession-self link.This study shows how self-investment affects the hoarding tendency of college students,and the results of this study also help demonstrate the value of self-investment and possession-self link in optimizing students’hoarding tendency and thus promoting good psychological status. 展开更多

Individuals’perceptions,attitudes,and patterns of getting along with family members are important factors influencing Chinese people’s self-evaluation.The aim of this study was to investigate the effect of family cohesion on depression and the role of perceived social support and intentional self-regulation in this association.A hypothesized model of the association of family cohesion,perceived social support,intentional self-regulation,and depression was examined.A convenience sampling method was used to survey 1,180 college students in Yunnan Province using self-report.Data were collected using the Family Cohesion Scale,the Perceived Social Support Scale,the Intentional Self-Regulation Scale,and the Center for Epidemiological Studies Depression Scale.The findings revealed low to moderate correlation between the variables studied.College students’family cohesion was a negative predictor of their depression.This association was also mediated by the knock-on effect of perceived social support and intentional self-regulation.These findings show how family cohesion affects college students’depressive status.Specifically,these results help demonstrate the importance of family cohesion,perceived social support,and intentional self-regulation in optimizing students’depression,which in turn can promote better psychological states. 展开更多

Signature verification,which is a method to distinguish the authenticity of signature images,is a biometric verification technique that can effectively reduce the risk of forged signatures in financial,legal,and other business envir-onments.However,compared with ordinary images,signature images have the following characteristics:First,the strokes are slim,i.e.,there is less effective information.Second,the signature changes slightly with the time,place,and mood of the signer,i.e.,it has high intraclass differences.These challenges lead to the low accuracy of the existing methods based on convolutional neural net-works(CNN).This study proposes an end-to-end multi-path attention inverse dis-crimination network that focuses on the signature stroke parts to extract features by reversing the foreground and background of signature images,which effectively solves the problem of little effective information.To solve the problem of high intraclass variability of signature images,we add multi-path attention modules between discriminative streams and inverse streams to enhance the discriminative features of signature images.Moreover,a multi-path discrimination loss function is proposed,which does not require the feature representation of the samples with the same class label to be infinitely close,as long as the gap between inter-class distance and the intra-class distance is bigger than the set classification threshold,which radically resolves the problem of high intra-class difference of signature images.In addition,this loss can also spur the network to explore the detailed infor-mation on the stroke parts,such as the crossing,thickness,and connection of strokes.We respectively tested on CEDAR,BHSig-Bengali,BHSig-Hindi,and GPDS Synthetic datasets with accuracies of 100%,96.24%,93.86%,and 83.72%,which are more accurate than existing signature verification methods.This is more helpful to the task of signature authentication in justice and finance. 展开更多

Generalized anxiety disorder(GAD)has harmful effects on physical and mental health and quality of life.Coloring therapy has been reported to have a positive effect on improving patient anxiety and depression.But there are no reported clinical trials examining their effectiveness as a treatment for GAD.This study was planned to evaluate the effectiveness of coloring therapy combined with conventional therapy in improving anxiety,depression,and positive and negative emotions with GAD.This randomized controlled study comprising 88 GAD patients was selected for intervention in different wards.The control group(n=45)was given conventional antianxiety medication and physical therapy,and the experimental group(n=43)received coloring therapy combined with conventional therapy.The Self-Rating Depression Scale,Self-Rating Anxiety Scale(SAS),Hamilton Depression Scale,Hamilton Anxiety Scale(HAMA),and Positive and Negative Affect Scale were assessed in both groups before and 3 weeks after the intervention.After the intervention,there were statistical differences in intra-and inter-group comparisons of anxiety,depression,and positive and negative mood scales in the experimental and control groups(p<.05).The minus in anxiety/positive emotions pre-and postintervention in the experimental group was statistically significant compared to that in anxiety/positive emotions pre-and postintervention in the control group(HAMA:d=1.45,95%confidence interval[CI](0.34,2.57),p=.011;SAS:d=3.87,95%CI(1.73,6.00),p=.001;positive:d=1.76,95%CI(0.17,3.34),p=.030).The minus in depressive/negative emotions pre-and postintervention in the experimental group was not statistically significant compared with that in depressive/negative emotions pre-and postintervention in the control group(p>.05).For GAD patients,adding coloring therapy based on conventional drug therapy and physical therapy can not only reduce depression and negative emotions but also have better effects on reducing anxiety and improving positive emotions than conventional therapy. 展开更多

Because the static evaluation is unable to reflect the dynamic features of economic benefits and the contribution of sustainable development of low-carbon new energy to economic benefits is huge,this article puts forward the dynamic evaluation model of economic benefits under the development of low-carbon new energy.Total energy,energy consumption structure,industrial structure,GDP,total population and energy supply structure were taken as independent variables,and the carbon intensity was taken as the dependent variable.Through t-test and decision coefficient,total energy,energy consumption structure,GDP and total population were determined as the main factors of influencing low-carbon economy.Based on these four main factors,the dynamic evaluation index system of economic benefits was constructed.Experimental results show that the proposed model can comprehensively reflect the economic benefit level and the contribution of low-carbon new energy.Therefore,this method has high evaluation accuracy,which can provide scientific reference for the economic benefit management of relevant management departments. 展开更多

Robust watermarking requires finding invariant features under multiple attacks to ensure correct extraction.Deep learning has extremely powerful in extracting features,and watermarking algorithms based on deep learning have attracted widespread attention.Most existing methods use 3×3 small kernel convolution to extract image features and embed the watermarking.However,the effective perception fields for small kernel convolution are extremely confined,so the pixels that each watermarking can affect are restricted,thus limiting the performance of the watermarking.To address these problems,we propose a watermarking network based on large kernel convolution and adaptive weight assignment for loss functions.It uses large-kernel depth-wise convolution to extract features for learning large-scale image information and subsequently projects the watermarking into a highdimensional space by 1×1 convolution to achieve adaptability in the channel dimension.Subsequently,the modification of the embedded watermarking on the cover image is extended to more pixels.Because the magnitude and convergence rates of each loss function are different,an adaptive loss weight assignment strategy is proposed to make theweights participate in the network training together and adjust theweight dynamically.Further,a high-frequency wavelet loss is proposed,by which the watermarking is restricted to only the low-frequency wavelet sub-bands,thereby enhancing the robustness of watermarking against image compression.The experimental results show that the peak signal-to-noise ratio(PSNR)of the encoded image reaches 40.12,the structural similarity(SSIM)reaches 0.9721,and the watermarking has good robustness against various types of noise. 展开更多

Collective behaviors efficiently impart benefits to a diversity of species ranging from bacteria to humans.Fly larvae tend to cluster and form coordinated digging groups under crowded conditions,yet understanding the rules governing this behavior is in its infancy.We primarily took advantage of the Drosophila model to investigate cooperative foraging behavior.Here,we report that Drosophila-related species and the black soldier fly have evolved a conserved strategy of cluster digging in food foraging.Subsequently,we investigated relative factors,including larval stage,population density,and food stiffness and quality,that affect the cluster digging behavior.Remarkably,oxygen supply through the posterior breathing spiracles is necessary for the organization of digging clusters.More importantly,we theoretically devise a mathematical model to accurately calculate how the cluster digging behavior expands food resources by diving depth,cross-section area,and food volume.We found that cluster digging behavior approximately increases 2.2 fold depth,1.7-fold cross-section area,and 1.9 fold volume than control groups,respectively.Amplification of food sources significantly facilitates survival,larval development,and reproductive success of Drosophila challenged with competition for limited food resources,thereby conferring trophic benefits to fitness in insects.Overall,our findings highlight that the cluster digging behavior is a pivotal behavior for their adaptation to food scarcity,advancing a better understanding of how this cooperative behavior confers fitness benefits in the animal kingdom. 展开更多

The authors,one from China and one from the United States,present a theoretical framework for understanding the discursive fields of citizenship education as composed,in large part,of the discourses of nationalism,globalization,and cosmopolitanism.The framework is illustrated by examples from citizenship education in China and the United States.Citizenship education in these examples is largely influenced by the discourse of nationalism.The discursive fields are fractured,context-specific,and dynamic.In conclusion,the authors call for awareness of how these discourses operate,and propose that the discourses of globalization and cosmopolitanism merge and strengthen within citizenship education.The effect could be a new citizenship education that is responsive to the current needs of local and global democratic communities. 展开更多
