In order to identify the effectiveness of teaching academic chess, the research was carried out among the Armenian primary schools in 2-4 grades of high, medium, and low academic performance, concentration, and barriers to students＇ attention towards stability, response rates, as well as the moving objects. The focus of barriers to sustainability is put on appraisal methods of analysis, it is clear that the barriers to sustainability assessment criteria are low, among the 4th grade students medium and high academic performance, there was an apparent increase in the number of true confrontation. Therefore, the stability of the learners＇ attention was increasing. The ＂counter the moving object＂ methodology results suggest that Reaction to Moving Object coefficient, which is equal to the number of delays and early confrontation quotient, is gradually decreasing, adding the exact number of confrontation. The aim of teaching academic chess at schools is to develop teaching and students＇ cognitive sphere, in particular, logical thinking, imagination, analyzing capacity, thus contributing to the academic study of other subjects.展开更多

Considering the effect of Chinese traditional cultural background, this study mainly investigates Chinese international high school students’ sleeping quality and patterns through the Pittsburgh Sleep Quality Index. Methods: A sample of 249 Chinese high school students in the Pearl River Region completed the questionnaire about their sleep quality using PSQI, their academic performance, and socio-demographic factors one month before the final exam in July 2023. Results: None of the students have good sleep quality, according to the PSQI;40.8% of students have poor sleep quality, and 59.2% have significant sleep disturbance. The results of ordinal logistic regression show that good sleep quality is positively associated with good academic performance. Conclusion: Our findings highlight the association between sleep and academic performance on the unique sleep patterns of Chinese international high school students, who often follow very different sleep patterns from other conventional students enrolled in the regular curriculum. High school students suffer from severe sleep deprivation and poor sleep quality. Under great academic stress, Chinese high school students should know the importance of sleep, balance sleep, and study.展开更多

How...Personal video recorders (PVRs) have altered the way users consume television (TV) content by allowing users to record programs and watch them at their convenience, overcoming the constraints of live broadcasting. However, standalone PVRs are limited by their individual storage capacities, restricting the number of programs they can store. While online catch-up TV services such as Hulu and Netflix mitigate this limitation by offering on-demand access to broadcast programs shortly after their initial broadcast, they require substantial storage and network resources, leading to significant infrastructural costs for service providers. To address these challenges, we propose a collaborative TV content recording system that leverages distributed PVRs, combining their storage into a virtual shared pool without additional costs. Our system aims to support all concurrent playback requests without service interruption while ensuring program availability comparable to that of local devices. The main contributions of our proposed system are fourfold. First, by sharing storage and upload bandwidth among PVRs, our system significantly expands the overall recording capacity and enables simultaneous recording of multiple programs without the physical constraints of standalone devices. Second, by utilizing erasure coding efficiently, our system reduces the storage space required for each program, allowing more programs to be recorded compared to traditional replication. Third, we propose an adaptive redundancy scheme to control the degree of redundancy of each program based on its evolving playback demand, ensuring high-quality playback by providing sufficient bandwidth for popular programs. Finally, we introduce a contribution-based incentive policy that encourages PVRs to actively participate by contributing resources, while discouraging excessive consumption of the combined storage pool. Through extensive experiments, we demonstrate the effectiveness of our proposed collaborative TV program recording system in terms of storage efficiency and performance.展开更多

These gaps required innovative problem-solving by public health agencies (PHAs), including local health departments (LHDs), to respond to rapidly changing community conditions during and after the pandemic. Many schools and programs of public health (SPPH) worked with PHAs to mobilize public health (PH) students through practice-based teaching (PBT). Current research indicates PBT benefits all stakeholders—PHAs, students, faculty, SPPH, and ultimately the community served. However, more research is needed on the utility of PBT in addressing a community’s systemic public health issues, the extent to which the academic-community collaboration enhances a PHA’s capacity, and the impact of the pedagogy on preparing the workforce for an evolving PH landscape. This paper examines the process of a semester-long PBT course, guided by the PBT STEPS framework, which includes five steps from collaboration to implementation to evaluation of a PBT course. The collaborating PHA and its student group addressed community trauma and resilience issues during the semester. Additionally, it examines the longer-term impacts after the semester for the PHA, community, and the workforce by 1) conducting a formative evaluation to understand needs and gaps in the community;2) redesigning an intervention that merged the results of the formative evaluation with the intervention developed during the semester;and 3) securing funding and resources for intervention sustainability. Through the documentation of a post-course partnership between an LHD and faculty at a large school of public health, this case study illustrates the potential for PBT to lay the foundation for ongoing research that supports more impactful interventions for PHAs while bolstering the workforce abilities of students as future practitioners.展开更多

First, by sharing storage and upload bandwidth among PVRs, our system significantly expands the overall recording capacity and enables simultaneous recording of multiple programs without the physical constraints of standalone devices. Second, by utilizing erasure coding efficiently, our system reduces the storage space required for each program, allowing more programs to be recorded compared to traditional replication. Third, we propose an adaptive redundancy scheme to control the degree of redundancy of each program based on its evolving playback demand, ensuring high-quality playback by providing sufficient bandwidth for popular programs. Finally, we introduce a contribution-based incentive policy that encourages PVRs to actively participate by contributing resources, while discouraging excessive consumption of the combined storage pool. Through extensive experiments, we demonstrate the effectiveness of our proposed collaborative TV program recording system in terms of storage efficiency and performance.
文摘Objectives:Academic Evaluation Anxiety is a significant psychological concern among adolescents,with well-documented impacts on academic performance,emotional well-being,and school engagement.In Portugal,recent evidence suggests growing pressure on students to achieve high academic standards,with psychosocial variables such as resilience,perceived support,and school environment playing a crucial role.This study aims to examine the prevalence and psychosocial predictors of Academic Evaluation Anxiety in Portuguese students,and to identify risk and protective factors that inform educational practice.Methods:This cross-sectional,quantitative study analysed data from 3083 students(5th to 12th grade)from the 2024 National Study by the Observatory of Psychological Health and Well-Being.Validated instruments were used,including the Depression,Anxiety and Stress Scale-21 items(DASS-21),the Social and Emotional Skills Scale(SSES),the Health Behaviour in School-aged Children(HBSC)psychological symptoms and well-being indices,the Positive Youth Development(PYD)scale,and the School Environment Scale.Statistical analyses included descriptive measures,one-way ANOVAs,and multivariate linear regression.Results:Academic Evaluation Anxiety was significantly higher among female students(Mean=2.80,SD=0.93)compared to male students(Mean=2.16,SD=1.10),representing approximately 30%higher mean levels of anxiety in girls(F=306.206,p<0.001).Resilience(β=−0.38,p<0.001),self-confidence(β=−0.07,p=0.02),and creativity(β=−0.06,p=0.01)emerged as protective factors,whereas cooperation(β=0.23,p<0.001),teacher relationships(β=0.08,p<0.001),bullying(β=0.07,p<0.001),and school environment(β=0.05,p=0.03)were positively associated with anxiety levels.Conclusions:Academic Evaluation Anxiety is highly prevalent among Portuguese adolescents,with girls reporting significantly higher levels than boys.Resilience,self-confidence,and creativity act as protective factors,while bullying,teacher relationships,cooperation,and negative school climate increase vulnerability.These findings highlight the need for whole-school strategies that strengthen socio-emotional competencies and create psychologically safe learning environments to support both well-being and academic success.
文摘Background:Academic stress is a critical factor influencing university students’well-being.However,research has shown that stress is not a unidimensional construct;different types of stressors(challenge vs.hindrance)may lead to distinct outcomes.This study constructed a structural equation model(SEM)to examine the relationships between challenge and hindrance academic stressors and students’well-being,as well as the mediating mechanisms.Methods:Data were collected from 836 undergraduates at six universities in China(58.4%female,41.6%male;Mean age=20.47±1.46 years).Descriptive statistics,Pearson correlations,and SEM with 5000 bootstrap resamples were conducted to test hypothesized paths and mediating effects.Results:Direct path analysis revealed that challenge stressors positively predicted meaning in life(β=0.329,p<0.001)but not academic self-efficacy(β=-0.004,p=0.915),while hindrance stressors negatively predicted meaning in life(β=-0.371,p<0.001).Meaning in life strongly predicted academic self-efficacy(β=0.543,p<0.001)and well-being(β=0.301,p<0.001),and academic self-efficacy further contributed to well-being(β=0.190,p<0.001).Bootstrapping confirmed that meaning in life significantly mediated the effects of both challenge(β=0.099,95%CI[0.063,0.144])and hindrance stressors(β=-0.112,95%CI[-0.162,-0.076])on well-being.The serial mediation pathway was also significant for both models(challenge:β=0.034,95%CI[0.019,0.049];hindrance:β=-0.038,95%CI[-0.057,-0.024]).Conclusions:This study partially validates the dual-pathway model of academic stress in higher education and highlights the pivotal roles of meaning in life and academic self-efficacy in the stress-well-being relationship.
文摘Ye Tianshi was a renowned expert in classical formulas during the Qing Dynasty.He created the Light Bitterness and Mild Pungency Method,which is formulated based on the compatibility of“Xing(bitter almond),Kou(Fructus amomi rotundus),Ju(tangerine peel),and Jie(platycodon root)”.This method regulates the dispersion and descent of lung Qi to dispel warm-heat pathogens and smooth the Qi movement of the triple energizer.In the treatment of lung system diseases,Ye classified them into two major categories based on etiology and pathogenesis:excess syndrome of nutrient-defense and deficiency syndrome of nutrient-defense.When discussing the treatment of cough caused by phlegm-fluid retention,he frequently referred to Synopsis of the Golden Chamber and attached great importance to summarizing and absorbing the academic thoughts of predecessors.As an accomplished expert in classical formulas,Ye Tianshi followed the academic essence of Xuanyuan and Qi Bo(founders of TCM theory)and respected the principles of Zhang Zhongjing’s classical formulas,integrating these theories in a coherent manner.With his masterful application of classical formulas to achieve remarkable curative effects,Ye’s academic viewpoints on treating lung system diseases still exert a profound influence on the modern clinical diagnosis and treatment of related diseases.
文摘The pandemic highlighted significant gaps in the public health infrastructure impacted by shortages of public health workers, an undertrained workforce, and years of disinvestment. These gaps required innovative problem-solving by public health agencies (PHAs), including local health departments (LHDs), to respond to rapidly changing community conditions during and after the pandemic. Many schools and programs of public health (SPPH) worked with PHAs to mobilize public health (PH) students through practice-based teaching (PBT). Current research indicates PBT benefits all stakeholders—PHAs, students, faculty, SPPH, and ultimately the community served. However, more research is needed on the utility of PBT in addressing a community’s systemic public health issues, the extent to which the academic-community collaboration enhances a PHA’s capacity, and the impact of the pedagogy on preparing the workforce for an evolving PH landscape. This paper examines the process of a semester-long PBT course, guided by the PBT STEPS framework, which includes five steps from collaboration to implementation to evaluation of a PBT course. The collaborating PHA and its student group addressed community trauma and resilience issues during the semester. Additionally, it examines the longer-term impacts after the semester for the PHA, community, and the workforce by 1) conducting a formative evaluation to understand needs and gaps in the community;2) redesigning an intervention that merged the results of the formative evaluation with the intervention developed during the semester;and 3) securing funding and resources for intervention sustainability. Through the documentation of a post-course partnership between an LHD and faculty at a large school of public health, this case study illustrates the potential for PBT to lay the foundation for ongoing research that supports more impactful interventions for PHAs while bolstering the workforce abilities of students as future practitioners.

文摘Objective and fair scholar evaluation promotes academic engagement and ensures proper allocation of research resources.However,current evaluation methods face challenges such as insufficient consideration of disciplinary differences,over-reliance on publication output,neglect of low-cited papers,and limited discriminative power.This paper proposes an improved evaluation metric—the Academic Equilibrium Value index(AEV-index)—based on academic equilibrium value.By incorporating weights for publication and citation tiers and integrating average publication and citation levels within disciplines,the AEV-index aims to offer a more comprehensive and equitable assessment of scholarly performance.Using Scopus data from computer science conference papers(2012-2021)across the subfields of"Network and Information Security","Computer Graphics and Multimedia",and"Artificial Intelligence",we weighted publications and citations to evaluate researchers'academic levels.The research findings indicate that:(i)The AEV-index enhances existing scholar evaluation metrics from multiple perspectives,providing a relatively reasonable and broadly applicable comprehensive evaluation index.(ii)The AEV-index is significantly correlated with traditional scholar evaluation indicators such as total publications,total citations,and the hindex,while also moderating disciplinary differences,thereby facilitating cross-disciplinary comparisons of academic influence.(iii)Additionally,the AEV-index mitigates the negative impact of low publication output,recognizes the value of low-cited but high-quality papers,and offers improved discriminative power,thereby addressing several limitations of existing evaluation metrics.
文摘BACKGROUND The impact of mental health,including anxiety,on academic performance has been studied in several countries,but few data exist for Sudan.AIM To investigate the correlation between anxiety scores and academic performance among adolescent schoolchildren in Northern Sudan.METHODS This cross-sectional study was carried out during the 2021–2022 academic year among schoolchildren from randomly selected schools in Almatamah locality,River Nile State,Northern Sudan.A questionnaire was used to collect the parti-cipants’sociodemographic data.Anxiety levels were assessed using the ques-tionnaire tools of the General Anxiety Disorder 7-item scale.Students’academic performance scores were obtained from school records.Multivariate linear regression was performed.RESULTS A total of 328 students participated in this study,comprising 156 boys(47.6%)and 172 girls(52.4%).The median[interquartile range(IQR)]age of the students was 14.9 years(13.9–15.6 years).The median(IQR)of the students’academic scores was 27.6%(22.2%–48.1%).The median(IQR)of the students’anxiety scores was 0(0–3).In univariate linear analysis,anxiety scores were positively associated with academic performance scores(coefficient=1.19,P value<0.001).In multivariate linear analysis,after controlling for age,sex,parental education,occupation,and body mass index-Z-score,anxiety scores were positively associated with academic performance scores(coefficient=0.60,P value<0.001).CONCLUSION The current study revealed a positive correlation between anxiety scores and students’academic performance scores.However,the association between mental health disorders,including anxiety,and academic performance is a complex issue.Therefore,further studies are recommended.
