Objective: To explore the effect of family therapy in improving parent-child relationship of adolescent depression. Methods: From January 2021 to December 2021, 100 cases of adolescent depression were observed, and 50 cases in each group were randomly divided into two groups. The control group received basic psychological guidance and the observation group received family therapy. The effective rate of treatment, depression score, intimacy and adaptability score, parents' emotional score, shame factor score and satisfaction degree of treatment were compared. Results: After family treatment, the effective rate of the observation group was significantly higher than that of the control group (P < 0.05). At the beginning of the group, the scores of the two groups were very close, and there was no significant difference (P > 0.05). After treatment, the scores of the two groups of patients were improved in different degrees, but the improvement degree of the patients in the observation group after family treatment was significantly better than that in the control group, and the difference was statistically significant (P < 0.05). After different treatment methods, the satisfaction degree of patients and their families in the observation group who received home treatment reached 96.00%, while that of the control group and their families who received routine treatment was only 78.00. The satisfaction degree of the observation group was much higher than that of the control group, with a significant difference (P < 0.05). Conclusion: In the choice of treatment methods for adolescents with depression, family therapy is more effective. After receiving treatment for a period of time, it can gradually improve the influence of depression, promote family harmony, promote intimacy and adaptability. In addition, the parents' emotions of patients are more stable, which can improve the patients' shame factor score. It has high popularization and application value. 展开更多

Objectives:To explore the approaches for reducing non-suicidal self-injury(NSSI)behaviors in Chinese adolescents,the present study investigated the association between parent-child conflict and NSSI in adolescents,while also examining the mediating role of depression and the moderating role of rumination thinking.Methods:A cluster sampling method was employed to select 1227 Chinese adolescents aged 12 to 18 as participants,who completed measures including the Parent-Child conflict,Depression,Rumination Thinking,and Non-Suicidal Self-Injury questionnaires.The present study used SPSS 26.0 to conduct the Descriptive statistics,correlation analysis,and reliability tests,and PROCESS 3.3 to test the hypothesis model.Results:(1)There is a positive correlation between parent-child conflict and NSSI in adolescents;(2)Depression mediates the relationship between parent-child conflict and NSSI in adolescents;(3)Rumination thinking acts as a moderator in the association between parent-child conflict and depression.This study finds the indirect effect of depression on NSSI behaviors among Chinese adolescents.Furthermore,the study also finds protective factors by examining the role of reducing individual rumination thinking in mitigating negative emotions following adverse experiences.In conclusion,this research provides a pathway and foundation for enhancing interventions targeting NSSI behaviors among Chinese adolescents.Conclusion:The relationship between parent-child conflict and NSSI in adolescents is positively correlated.Depression acts as a mediator in the association between parent-child conflict and NSSI in adolescents.The effect of parent-child conflict on NSSI is positively moderated by rumination thinking.Specifically,low-level rumination thinking may mitigate the negative impact of parent-child conflict on depression. 展开更多

The implementation of China’s three-child fertility policy has led to a notable increase in multiple-child families.Notably,firstborn children experience a significant transition from being an only child to a non-only child.This transition is associated with problematic behaviors,affecting their social adjustment,sibling relationships,and family harmony.Although several studies have examined the relationship between parent-child attachment and problem behaviors exhibited byfirstborn children during family transitions,thefindings have been inconsistent.Hence,a meta-analytic study was undertaken to elucidate the inconsistencies in this relationship and explore the moderating factors that may contribute to these discrepancies.Using a systematic literature retrieval and screening method,12 effect sizes were derived from the 10 eligible articles,encompassing a sample size of 5319.The meta-analysis demonstrated a low negative association between parent-child secure attachment and problem behaviors exhibited byfirstborn children during family transitions.Furthermore,the present study investigates potential moderator factors,such as children’s age and geographic region,to gain a more nuanced understanding of the relationship.Consequently,the establishment of parent-child attachment relationships has the potential to mitigate problem behaviors observed infirst-born children during family transitions.The implications of thesefindings indicate that parents can nurture secure attachment bonds with their children by demonstrating sensitive responsiveness,employing positive parenting practices,and fostering emotional availability.These efforts contribute to the cultivation of secure internal working models and positive behavioral manifestations withinfirst-born children,which in turn affect their relationships with siblings. 展开更多

With the widespread adoption of smartphones,parental phubbing behaviors have become increasingly prevalent,potentially affecting preschool children’s development.Current research primarily focuses on adolescent populations,while the mechanisms through which parental phubbing and authoritarian parenting style influence preschool children’s behavioral problems within the Chinese cultural context remain to be explored.Our investigation seeks to examine the factors contributing to behavioral difficulties among children of preschool age and provide theoretical guidance for prevention.Methods In our research,we utilized a convenience sampling approach to collect data from parents whose children(n=612)were between 3 and 7 years of age.The questionnaire distribution was facilitated via the Wenjuanxing online survey platform.Research instruments included the Parental Phubbing Scale,Parent-Child Relationship Scale,Authoritarian Parenting Style Scale,and Conners Child Behavior Rating Scale.For analytical procedures,we employed SPSS 24.0 to generate descriptive statistics and correlation analysis.Chain mediation effects were examined via Process macro,while significance assessment of the mediating effects relied on the Bootstrap method for constructing 95%confidence intervals.Results A statistically significant positive association was observed between parental phubbing and behavioral problems exhibited by children(r=0.251,p<0.001).Parental phubbing exhibited a significant direct effect on children’s behavioral problems(β=0.088,p<0.001).Analysis of sequential mediation demonstrated that authoritarian parenting style together with parent-child conflict functioned as significant intermediary variables in the relationship between parental phubbing and children’s problem behaviors(β=0.163,p<0.001),with these indirect pathways constituting 64.94%of the total effect.Conclusion Parental phubbing significantly contributes to behavioral problems in preschool children.Parents should monitor their media use,improve their parenting approach,and enhance parent-child relationships to reduce behavioral problems in preschool children. 展开更多

This article attempts to distinguish public relations(PRs)from propaganda,within the context of information management.Speedy dissemination of information is an important feature of contemporary communication practice globally.In this era,the information content of communication is an important element requiring critical evaluation.This is so,because of the need to safeguard the information ecosystem,considering the thin line between public relations and propaganda.While both propaganda and public relations aim to shape perceptions,influence attitudes,and sway opinions,one key distinction lies in their ethical considerations.Public relations emphasize honesty,accuracy,accountability,and a commitment to the truth.In contrast,propaganda may involve manipulation,distortion,or even fabrication of information to advance a particular agenda,often at the expense of truth and transparency.Hinged on The Excellence Theory and the Two-Way Symmetrical Model,the paper focuses on the meeting points and differences between public relations and propaganda,with a view to safeguarding the integrity of the information ecosystem.The study adopted the survey research method,with interview as research instrument.The study discovered that while propaganda is not entirely a bad practice,it has a heavy tilt towards bias.It therefore recommends that deliberate steps be taken by relevant professional organisations and other stakeholders towards educating the citizens on ways of distinguishing between public relations and propaganda contents. 展开更多

Purpose:This paper presents a new semi-automatic methodology for identifying inter-actor relationships by discerning viewpoints in non-social,political textual corpora.Although previous research has successfully discerned viewpoints,biases,and affiliations based on textual features,the task of relationship analysis in the absence of interactional data remains unaddressed.Design/methodology/approach:We introduce a new paradigm for topic representation as a dynamic,continuous,multi-viewpoint spectrum based on the representation of viewpoints as vectors that capture common topical themes.As a proof of concept,we applied this paradigm to scrutinize the inter-state relationships reflected in the speeches of the UN General Assembly Debate Corpus(UNGDC).Findings:The proposed paradigm effectively identifies discursive trends in UNGDC.Our analysis reveals common attitudes towards the topic and their prominence among different groups of actors and facilitates the analysis of relationships between actors through a quantitative representation of viewpoint similarity.The method also successfully captured temporal shifts in viewpoints and overall discourse trends,correlating with major geopolitical events.Research limitations:One limitation of this study is the method’s sensitivity to data sparsity,which can skew viewpoint representations in cases of low topic involvement.Practical implications:The proposed paradigm can be utilized by scholars in political science and other domains as a tool for semi-automated unsupervised textual analysis of various non-social textual sources,enabling the discovery of latent relationships between actors and the modeling of viewpoints in complex topics.Originality/value:This study presents a novel framework for unsupervised semi-automatic textual analysis of relationships in non-social corpora through a new approach for the representation of viewpoints as thematic vectors. 展开更多

In contemporary society,language transcends its function as a mere tool for communication.It is intrinsically linked to a people’s culture,values,and worldview.This observation is particularly salient in our globalized world,where linguistic considerations have assumed strategic importance.Recognizing this potential,numerous states are seeking to bolster their international relations by prioritizing the teaching of their languages.It is within this context that we focus our attention on the teaching of Chinese in Congo-Brazzaville.Our objective is to investigate the significance of this language in consolidating bilateral relations between China and Congo.To achieve this,we analyze the current state of Chinese language instruction within the Congolese educational system,emphasize the implications of its dissemination,and propose potential avenues for improvement.Our approach is qualitative,drawing upon observations,interviews,and a review of existing literature.We aim to understand how the teaching of Chinese can contribute to the economic,cultural,and social development of Congo,while simultaneously strengthening ties with China. 展开更多

Trump's victory in November 2024 once again had a strong impact on the European Union.However,unlike when Trump won the election for the first time in 2016,there have been some disturbing development trends in US-Europe relations.The imbalance in relations between the US and Europe has become even more pronounced.Whether in important fields such as the economy,finance,science and technology,or the military,the gap between the European Union and the United States is widening.Meanwhile,Europe's dependence on the United States is also increasing.Especially since the outbreak of the Ukraine crisis,it has formed an all-round dependence on the United States in terms of security,energy,markets,as well as capital and technology.The increasing imbalance in US-Europe relations has triggered anxiety in Europe,including concerns that Europe might become a“vassal”of the United States.During Trump's second term,Europe may be more inclined to cater to the United States and submit to its demands more often.However,under internal and external pressures,it may also accelerate the process of promoting strategic autonomy.Where the European Union will go will largely depend on the direction and intensity of policy adjustments during Trump's second term. 展开更多

China’s path to modernization,which embodies a unique developmental model characterized by high-quality development,common prosperity,harmony with nature,and peaceful coexistence,is a multifaceted process that advances progress on multiple fronts.This paper applies two analytical lenses to the study of intergovernmental fiscal relations:multi-level governance,where different levels of government interact,and multi-objective decision-making,where multiple goals are pursued simultaneously.From this perspective,it puts forward three core propositions.First,the evolution of fiscal relations is shaped primarily by the central government’s need to balance incentivization,coordination,and control.Second,these relations are constrained by objective factors such as the output elasticity of loacl government actions,cost coefficients,externalities,and uncertainty.Third,the effectiveness of both central and local governments depends on the design of fiscal relations,as well as on their objectives,the output elasticity of actions,and costs.In essence,effective intergovernmental fiscal relations require a balance between centralized leadership and local initiative.Using this framework,the paper examines how changes in China’s fiscal system have influenced modernization across different historical periods,offering a theoretical model tailored to China’s national context. 展开更多

Feature selection methods rooted in rough sets confront two notable limitations:their high computa-tional complexity and sensitivity to noise,rendering them impractical for managing large-scale and noisy datasets.The primary issue stems from these methods’undue reliance on all samples.To overcome these challenges,we introduce the concept of cross-similarity grounded in a robust fuzzy relation and design a rapid and robust feature selection algorithm.Firstly,we construct a robust fuzzy relation by introducing a truncation parameter.Then,based on this fuzzy relation,we propose the concept of cross-similarity,which emphasizes the sample-to-sample similarity relations that uniquely determine feature importance,rather than considering all such relations equally.After studying the manifestations and properties of cross-similarity across different fuzzy granularities,we propose a forward greedy feature selection algorithm that leverages cross-similarity as the foundation for information measurement.This algorithm significantly reduces the time complexity from O(m2n2)to O(mn2).Experimental findings reveal that the average runtime of five state-of-the-art comparison algorithms is roughly 3.7 times longer than our algorithm,while our algorithm achieves an average accuracy that surpasses those of the five comparison algorithms by approximately 3.52%.This underscores the effectiveness of our approach.This paper paves the way for applying feature selection algorithms grounded in fuzzy rough sets to large-scale gene datasets. 展开更多
