Promoting smallholder farmers’ adoption of modern agricultural production technology is one effective way to improve the capabilities of smallholder farmers. This paper aims to explore the impact of Internet use on the adoption of agricultural production technology by smallholder farmers based on a survey of 1 449 smallholders across 14 provinces in China. The results suggest that Internet use can significantly promote technology adoption, with the probability of adopting new crop varieties, water-saving irrigation technology and straw-returning technology increasing by 0.200, 0.157 and 0.155, respectively. Furthermore, the effect of Internet use is found to be heterogeneous with a greater effect on smallholder farmers having low education levels, limited training, and high incomes. To increase agricultural production technology adoption by smallholders, rural Internet infrastructure and Internet use promotion should be the focus for the Chinese government.展开更多

As teenagers are in a complicated period of development, parents struggle in supervising their use of the intemet. This study takes the teenagers＇ standpoint and explores how the teenagers perceive their parents＇ involvement in their Internet use. Survey was conducted towards teenagers in the UAE, which has the highest penetration of digital devices in the Gulf region as well as one of the highest in the world. The results showed that girls usually receive more supervision fi＇om parents than boys. The older the teenagers are and the more they depend on the Internet, the more they perceive parents＇ supervision to be beneficial. However, not enough supervision has been given to those who access the Internet more frequently. The findings indicate more parents＇ supervision is needed from the teenagers＇ point of view.

文摘Background:Resilience is crucial for medical college students to thrive in the highly stressful environment of medical education.However,the prevalence of problematic internet use(PIU)in this population may negatively impact their resilience.This study investigated the influence of problematic online gaming(PG)and problematic social media use(PSMU)on the resilience of medical college students in China.Methods:A sample of 5075 first-year medical college students from four Chinese universities was studied.PG served as the independent variable,resilience as the dependent variable,fatigue as the mediator,and PSMU as the moderator.Structural equation modeling was conducted using LISREL 8.80.Additionally,a moderated mediation model was evaluated using the jAMM module in jamovi 2.6.13.Results:The study’s findings revealed significant negative correlations between resilience and the variables of PG,PSMU,and fatigue.Fatigue mediated the relationship between PG and resilience(B=−0.04,95%CI=[−0.05,−0.03]).PSMU moderated the direct relationship between PG and resilience with the interaction term PG×PSMU significant(B=−0.004,t=−6.501,p<0.001)and the first stage(PG→fatigue)of the mediation with PG×PSMU significant(B=0.055,t=8.351,p<0.001).The detrimental effects of PG on resilience were more pronounced among individuals with lower levels of PSMU.Conclusion:This study concluded that addressing PIU,particularly PG,is essential for fostering resilience in medical college students.While PSMU itself is maladaptive,the underlying social media engagement may serve a protective role through social support in mitigating the adverse effects of PG on resilience.
文摘Internet use has become an indispensable part of people’s daily lives,and the relationship between Internet use and residents’subjective well-being is receiving increasing attention from researchers.However,the existing literature on the relationship between Internet use and residents’subjective well-being is still controversial and inconclusive,and there has been relatively little discussion of the mechanisms by which Internet use affects well-being.On the basis of data from the China General Social Survey 2015(CGSS2015),this paper provides an empirical analysis of the impact of Internet usage on residents’subjective wellbeing.The study finds that while Internet use had no significant impact on the well-being of residents compared to non-use,frequency of Internet usage did significantly improve subjective well-being.On this basis,we tested the mechanisms by which Internet use affects residents’well-being through the three channels of the personal income effect,the human capital effect and the social capital effect.The findings partially verify the hypothesis of the mediating effect of social capital between Internet use and residents’subjective wellbeing,but do not verify the hypothesis of the moderating effect of personal income and human capital.Compared with previous studies,this paper is innovative in the following three ways:it uses the latest available representative national microdata,which is better able to reflect recent Internet usage and its impact on residents’subjective well-being;on the basis of existing research on the impact of Internet usage on residents’well-being,it analyzes the specific mechanisms through which Internet use affects well-being,using the moderating effect model and the mediating effect model to make up for the shortcomings of existing research on the impact mechanism;and it applies the Bioprobit model to deal with the potential endogeneity of key explanatory variables,using a variety of model estimation methods to obtain more robust estimation results.
文摘Importance:Several studies conducted worldwide(mostly in Western countries)highlighted the negative effects of problematic internet use,particularly among adolescents aged 12 to 17,including depression,impulsivity,aggression,and social fear and avoidance.In Lebanon,literature on the prevalence and impact of problematic internet use among adolescents is limited.Objective:This study aim was to study the association between problematic internet use and depression,impulsivity,anger,aggression and social phobia among Lebanese adolescents.Methods:A cross-sectional study was performed on 1103 young adolescents(14-17 years),recruited from October 2017 till April 2018.The Internet Addiction Test(IAT)was used to evaluate the level of problematic internet use.Data were analyzed using the MANCOVA analysis.The main independent variable of interest was the IAT,while the dependent variables included the psychological scales.Results:The multivariate analysis taking the psychological scales as the dependent variables and the problematic internet use(IAT score)as an independent variable,showed that problematic internet use was associated with higher depression,impulsivity,aggression,anger,hostility and social anxiety.Interpretation:Problematic internet use has become an important health issue that should not be overlooked,particularly because of the increased use of the internet by adolescents.Educational programs on early exposure to the internet should be developed.
文摘The Internet penetration rate rises sharply in recent years in China.This change has had a significant impact on residents’income.By using Chinese General Social Survey(CGSS)data set,this paper investigates whether residents who use the Internet earn a higher income than similar residents who do not use the Internet by using propensity score matching.The results show that there is a premium associated with Internet use.Estimates suggest that a premium for residents who use the Internet is around twice as much for residents who do not use the Internet.Additionally,this paper fi nds that the inlome differences between using the Internet and not using the Internet for groups of middle-aged and elderly resident and agricultural household registration residents are more significant.Based on the research results,several relevant policy implications are presented to improve resident’s income.
文摘The Internet of Things （IoT） has received much attention over the past decade. With the rapid increase in the use of smart devices, we are now able to collect big data on a daily basis. The data we are gathering （and related problems） are becoming more complex and uncertain. Researchers have therefore turned to artificial intelligence （AI） to efficiently deal with the problems ereated by big data.

文摘Clarifying the relationship between internet use and public information security risk perception helps us gain a better understanding of the factors influencing public risk perception.However,the relationship is still under-explored.This paper empirically examines the relationship between internet use and information security risk perception based on data from the 2021 Chinese Social Survey.It was found that whether to use the internet and the frequency of use are both significantly positively correlated with the perception of information security risk.On this basis,the mechanism by which internet use affects public information security risk perceptions is verified from the perspective of interpersonal trust.The mechanism analysis found that interpersonal trust exerts an indirect effect between internet use and perceived information security risk.The findings of this study provide new insights for our further understanding of how internet use affects residents'perceptions of securityrisk.

文摘Background:Although previous studies indicate that perceived social support might be associated with adolescent psychological problems,the specific mechanism has not been thoroughly discussed.Based on theoretical and empirical research on problematic Internet use(PIU)and sleep quality,this study explored whether they play a mediating role between perceived social support and symptoms of depression and anxiety among adolescents.Furthermore,we investigated whether these relationships varied by place of residence.Methods:A sample of 2115 Chinese adolescents was included,and analyzed data related to perceived social support,PIU,sleep quality,symptoms of depression and anxiety,and sociodemographic variables.Correlation analysis,mediation,and moderation analysis were mainly used.Results:Perceived social support was negatively correlated with depressive symptoms(r=−0.22,p<0.001)and anxiety symptoms(r=−0.20,p<0.001)among adolescents.PIU and sleep quality played a chain mediating role in the relationship between perceived social support and symptoms of depression and anxiety in adolescents.Additionally,the place of residence moderated the relationships between perceived social support and PIU and symptoms of depression and anxiety.Perceived social support was a significant negative predictor of PIU and symptoms of depression and anxiety among adolescents in urban areas but not in rural areas.Conclusion:The findings suggest that low levels of perceived social support may lead to more PIU and poorer sleep quality,which may further increase the risk of symptoms of depression and anxiety in adolescents,especially in urban areas.
