Some studies have found significant effect sizes while others have found low and non-significant effect sizes. Television effects scholars have postulated that these mixed results are caused by the inconsistencies of research methodology employed and the inability to control major mediating variables in the studies. The present study is designed with the objectives to overcome these shortcomings. The respondents for this study were 514 students aged between 13 and 18 from 10 schools in the State of Perak, Malaysia. Exploratory data analyses provided evidence that the employed instruments achieved sound psychometric properties. Hypotheses testing suggested that exposure to the Contents of Television Violence （TVCN） did not have a direct relationship with adolescents＇ aggressive behaviours; instead, Contextual Features of Television Violence （TVCX） totally mediated this relationship. Some other mediating variables then mediated totally and some mediated partially the relationship between TVCX and adolescents＇ aggressive behaviours. To conclude, this study provides valuable information for parents, the television industry, and the policy makers in recognizing pro-violent and anti-violent features of television violence programmes for Malaysian school-going adolescents. It also provides a new perspective for future studies of television violence in Malaysia.展开更多

However, this paper is from another perspective, based on the social background of high-quality development, the main study is the impact mechanism of urban and rural income gap on the industrial structure, taking the Yangtze River Delta as the main research object, and specifically selecting 22 central cities in the Yangtze River Delta region, which is also one of the highlights of this study. The regression model is constructed by using the intermediary effect, and the four intermediary variables of fiscal expenditure (M<sub>1</sub>), fixed asset investment (M<sub>2</sub>), number of patent applications (M<sub>3</sub>), and total import and export (M<sub>4</sub>) are selected, which represent the role of the government, fixed asset investment, scientific and technological level and opening-up level, and study and analyze the inherent influence mechanism between each variable. Before doing specific research, I consulted the papers and literature of many other outstanding scholars, among which Cheng Yuhong and Cheng Chi’s “The Influence Mechanism of industrial structure of urban and rural income gap” [1] has great reference value for this paper. According to the research results, under the background of high-quality development in the Yangtze River Delta region, the expansion of the income gap between urban and rural areas will inhibit the upgrading of the industrial structure, so it is necessary to focus on building a new type of urbanization, accelerating the construction of an urban innovation system, optimizing the rural employment structure to narrow the income gap between urban and rural areas, and providing impetus for the continuous upgrading of the industrial structure.展开更多

文摘Background:Physical inactivity is a major public health problem worldwide that results in physical and mental health problems.One major issue for physical inactivity is weight stigma(WS),especially perceived WS,which could lead to a tendency to avoid physical activity(PA).To better understand the association between perceived WS and PA,knowledge of the likely mediators in this association such as weight bias internalization(WBI)and psychological distress were investigated in the present study.Methods:Using a two-wave longitudinal study and convenient sampling,388 Taiwan residents participants(55%females;mean age=29.7 years[SD±6.3])completed two surveys six months apart.Body mass index(BMI),Perceived Weight Stigma Scale(PWSS),Weight Bias Internalization Scale(WBIS),Depression,Anxiety,Stress Scale(DASS-21),and Tendency to Avoid Physical Activity and Sport Scale(TAPAS)were assessed.Results:A mediation model controlling for age,gender,and BMI with 5000 bootstrapping resamples was performed.Perceived WS exerted significant direct effects on WBI(β=0.25;p<0.001),psychological distress(β=0.15;p=0.003),and tendency to avoid PA(β=0.10;p=0.027);WBI exerted a significant direct effect on tendency to avoid PA(β=0.47;p<0.001).Standardized indirect effects of WBI and psychological distress on the association between perceived WS and tendency to avoid PA were 0.12 and 0.01,respectively.Conclusion:Given the direct association of perceived WS on the tendency to avoid PA and the mediating role of WBI in this association,interventions addressing perceived WS and WBI may contribute to promoting PA.Therefore,health interventionists(both when planning and executing PA programs)need to consider weight stigmawhen encouraging physical activity.

However, this paper is from another perspective, based on the social background of high-quality development, the main study is the impact mechanism of urban and rural income gap on the industrial structure, taking the Yangtze River Delta as the main research object, and specifically selecting 22 central cities in the Yangtze River Delta region, which is also one of the highlights of this study. The regression model is constructed by using the intermediary effect, and the four intermediary variables of fiscal expenditure (M<sub>1</sub>), fixed asset investment (M<sub>2</sub>), number of patent applications (M<sub>3</sub>), and total import and export (M<sub>4</sub>) are selected, which represent the role of the government, fixed asset investment, scientific and technological level and opening-up level, and study and analyze the inherent influence mechanism between each variable. Before doing specific research, I consulted the papers and literature of many other outstanding scholars, among which Cheng Yuhong and Cheng Chi’s “The Influence Mechanism of industrial structure of urban and rural income gap” [1] has great reference value for this paper. According to the research results, under the background of high-quality development in the Yangtze River Delta region, the expansion of the income gap between urban and rural areas will inhibit the upgrading of the industrial structure, so it is necessary to focus on building a new type of urbanization, accelerating the construction of an urban innovation system, optimizing the rural employment structure to narrow the income gap between urban and rural areas, and providing impetus for the continuous upgrading of the industrial structure.

文摘Background:Adolescents frequently engage in Non-Suicidal Self-Injury(NSSI),with recent trends indicating an increase in this behavior.At the same time,Chinese adolescents have a higher incidence of NSSI than Western adolescents.Therefore,it is necessary to explore the relationship between interparental conflict and NSSI among adolescents within the context of Chinese families.Methods:The research sample comprised 755 senior high school students(46.62%male;age M=16.82,SD=0.94 years)who completed the Interparental Conflict Child Perception Scale(CPIC),Adolescent Self-Injury Behavior Questionnaire(ASHS),Toronto Alexithymia Scale-20(TAS-20),and Scale of Adolescent Resilience(RSCA).Results:Findings suggest that interparental conflict is a significant positive predictor of NSSI(r=0.22,p<0.01).Alexithymia mediates the relation between interparental conflict and NSSI(effect size=0.09,95%CI[0.05,0.13]).Additionally,resilience moderates both the direct relation(β=−0.08,p<0.05)and the latter half of the mediating pathway(β=−0.08,p<0.05)in the moderated mediation model.Conclusion:This study indicates that interparental conflict have an impact on adolescents’NSSI in Chinese families,and alexithymia and resilience play important roles in the relationship.These findings offer valuable guidance for the prevention and intervention efforts targeting NSSI among adolescents in China and in similar family contexts.
