This study tries to explore the popularity of the social media sites, the level of use of the social media sites, the types of information-sharing activities involved on the social media sites, to compare youth of various background in relation to information-sharing activities, and to analyze the relationship between the level of social media use and the information-sharing activities among youth. This study employs a quantitative research design, using survey method with questionnaire as the research instrument used for data collection. In this study, youth aged between 17-40 years old nationwide were surveyed. The study was developed based on the user and gratification theory （Blumler ＆ Katz, 1974）. Findings showed that youth always （five to seven days per week） use social media to share information including personal information. Results also showed that youth used the social media more for sharing negatively-oriented information compared to the positively-oriented information. Although there were more items on the positively-oriented information-sharing activities but more youth spent their time on the negatively-oriented information-sharing activities. The results are supported by a strong relationship between frequency of use and the negatively-oriented information-sharing activities.展开更多

However, the sharp increase in social media usage has led to concerns about mental health and overall well-being. While social media can be valuable for staying connected with friends and being informed about the world, it can also bring about a multitude of problems, especially among the youth. This paper aims to examine available research on the relationship between social media and issues such as depression, anxiety, and cyberbullying among adolescents. Furthermore, it will explore how childhood maltreatment can affect how an individual interacts with social media. This paper not only explains how social media could have a negative effect on adolescents, with many of the aforementioned problems being linked to social media usage, but also how social media could also bring about some benefits. However, further research is needed to better understand the complexity of youth’s relationship with social media.展开更多

The study focused on the variables that may affect how social media is used for disaster management. Structural equation modeling (SEM) was utilized in the study to analyze the data and test the hypotheses after using a survey questionnaire to collect the data. The study’s findings show that: 1) communities that are vulnerable to disasters are less likely to use social media for disaster management, 2) personal effort and intention to use social media for disaster management are positively correlated, and 3) task complexity and intention to use social media for disaster management are negatively correlated. The study added to the body of knowledge regarding the role social media plays in disaster management.展开更多

For this purpose, we discuss the concept of ＂Lusophone＂ and ＂Lusophone＂ migration system, and we present the context of immigration in Portugal. The empirical work involved 14 in-depth interviews2 and started by presenting, in broad strokes, some important aspects relating to the history of ＂Lusophone＂. The analysis of the interviews was sustained in the theories of economic and political ＂world-system＂ developed by Braudel （1949） and Wallerstein （2004） and extended to the concept of migration systems of Kritz and Zlotnik （1992）. Their proposals were further developed by the Portuguese sociologist Baganha （2009） who defended the particularity of a ＂Lusophone＂ migration system. Based on those concepts, we describe the theoretical and empirical research and methodological procedures, stressing the trajectories of migration, social mobility and consumption of media and Information Communication Technologies （ICT）. We analyze the interviews, highlighting the similarities and differences, regarding the uses and consumptions of media and ICTs, between Brazilians and Finally based on the results, we discuss the characteristics the citizens from Portuguese-speaking African Countries of this ＂Lusophone＂ media system.展开更多

Scientists tend to attribute such conflict to inadequate public knowledge of science, leading to misunderstandings about it. However, that view ignores the influence on public perceptions of news reports and online discussions about controversial technologies in new media. Social media reporting affects the audience's perception of the risks posed by controversial technologies and can cause people to lose confidence in the scientific community and damage their trust in government. Thus, the public opposes these technologies. In this context, this study explores the relationship between the public's trust in the scientific community and the government on the one hand and its attitude towards controversial technologies on the other. I surveyed 1,235 people using a national online probability sampling strategy. I found that people's use of new media was significantly related to the extent of their knowledge of specific controversial technologies and was associated with other people's opinions about those technologies. The more attention people paid to We Chat coverage of genetically modified organisms(GMOs), the more supportive they were of them. Thus, the public's use of new media is a key factor in predicting its positive attitude to GMOs. Scientific literacy also significantly affects public attitudes to GMOs, directly as well as indirectly.展开更多

文摘Sleep quality is closely linked to people’s health,and during the COVID-19 pandemic,the sleep patterns of residents in China were notably poor.The lockdown in China led to an increase in social media use,prompting questions about its impact on sleep.Therefore,this study investigates the association between social media use and sleep quality among Chinese residents during the COVID-19 outbreak,highlighting the potential mediating role of social media addiction.Data were collected via questionnaires through a cross-sectional survey with 779 valid responses.Variance analysis was used to test for differences in social media use among different demographic variables.Bivariate correlation analysis was employed to explore the relationships between variables,while regression analysis investigated the correlations between various media factors and sleep quality.Additionally,Bootstrap sampling was utilized to analyze the potential mediating influence of social media addiction in the relationship between social media use and sleep.The study's findings reveal a significant correlation between social media use,particularly before bedtime,and sleep quality(p<0.01),with pre-sleep activity notably linked to poorer overall sleep scores(β=0.141,p=0.004).Although the daily use of social media did not directly impact most individuals’sleep quality,specific platforms like news apps,short video apps,dating apps,and content community platforms were associated with higher levels of social media addiction,subsequently negatively affecting sleep quality.Specifically,the use of news apps(B=0.068,95%CI[0.000,0.019]),short video apps(B=0.112,95%CI[0.001,0.031]),dating apps(B=0.147,95%CI[0.000,0.028]),and content community platforms(B=0.106,95%CI[0.001,0.028])was found to increase the risk of social media addiction,subsequently leading to adverse effects on sleep quality.The study underscores a notable link between social media use and sleep quality,suggesting that mindful social media habits,particularly before bedtime,and reducing addiction-associated apps could enhance sleep quality.
文摘Social media are popular among youth for sharing information. This study tries to explore the popularity of the social media sites, the level of use of the social media sites, the types of information-sharing activities involved on the social media sites, to compare youth of various background in relation to information-sharing activities, and to analyze the relationship between the level of social media use and the information-sharing activities among youth. This study employs a quantitative research design, using survey method with questionnaire as the research instrument used for data collection. In this study, youth aged between 17-40 years old nationwide were surveyed. The study was developed based on the user and gratification theory （Blumler ＆ Katz, 1974）. Findings showed that youth always （five to seven days per week） use social media to share information including personal information. Results also showed that youth used the social media more for sharing negatively-oriented information compared to the positively-oriented information. Although there were more items on the positively-oriented information-sharing activities but more youth spent their time on the negatively-oriented information-sharing activities. The results are supported by a strong relationship between frequency of use and the negatively-oriented information-sharing activities.
文摘This study examines generational differences in media use based on pooled-data analysis of CGSS(Chinese General Social Survey)2010-2015.In order to show a full picture of the substitutability between new and old media,the study brings age heterogeneity of respondents and time effect into consideration.This study distinguishes four generations based on the year of birth,with the“newspaper generation”(people who born before 1969),“broadcast generation”(1970-1979),“TV generation”(1980-1989),and“Internet generation”(born after 1990)and aims to explore whether generations differ in their frequency of media use.The research analyses five-year pooled data CGSS 2010-2015(CGSS 2014 data is missing)to examine the influence of Internet on old media among different birth cohorts and how this effect changes over time.New media refers to the Internet;old media includes newspaper,broadcast,and television.The results are summarized as follows:First,for the“newspaper generation”,“broadcast generation”,and“TV generation”,Internet heavy users are usually more willing to use newspaper and broadcast as well.Internet heavy users are information seekers.They have a strong need of information and usually are involved in multi-tasking media activities.Nevertheless,only the Internet heavy users in“TV generation”will regard TV as another channel to get more information,which indicates that generations may adopt specific patterns of media use when they are young and remain faithful to those throughout their lifespans.“TV generation”have a stronger attachment to television than their previous and later generation.Second,in terms of the time effect,the empirical data proved that the broadcast shows a stronger vitality in digital age compared with newspaper and television.The frequency of broadcast use does not drop significantly until 2015.However,the frequency of newspaper and television use has shown a significant downward trend since 2011.Third,for the“Internet generation”,the use of the Internet has no effect on the use of other media.Even Internet heavy user,the one who has strong need of information,would not choose other media to search more information.This suggests that these digital natives would rather confine themselves to the Internet cocoon than collect new information through old channels.This study provides new insight to understand the current media ecology.The relationship between the new and the old media is a changeable and dynamic process and cannot be simply understood as“more-more”or“more-less”relationship.

文摘There are several theoretical reasons to believe that overall media use might be related to attention deficit hyperactivity disorder(ADHD)or ADHD-related behaviors(i.e.,attention problems,hyperactivity,and impulsivity).Although studies on media-ADHD relationship have accumulated,they have yielded inconsistent results,especially those from different countries.Therefore,it is still undisclosed whether children’s overall media use and ADHD-related behaviors are related to region and culture.A meta-analysis has been performed on three empirical studies investigating the relationship between overall media use and ADHD-related behaviors in children and adolescents from China.The results indicated significant relationship between overall media use and ADHD-related behaviors,OR=2.597.
文摘The problematic use of social media has numerous negative impacts on individuals'daily lives,interpersonal relationships,physical and mental health,and more.Currently,there are few methods and tools to alleviate problematic social media,and their potential is yet to be fully realized.Emerging large language models(LLMs)are becoming increasingly popular for providing information and assistance to people and are being applied in many aspects of life.In mitigating problematic social media use,LLMs such as ChatGPT can play a positive role by serving as conversational partners and outlets for users,providing personalized information and resources,monitoring and intervening in problematic social media use,and more.In this process,we should recognize both the enormous potential and endless possibilities of LLMs such as ChatGPT,leveraging their advantages to better address problematic social media use,while also acknowledging the limitations and potential pitfalls of ChatGPT technology,such as errors,limitations in issue resolution,privacy and security concerns,and potential overreliance.When we leverage the advantages of LLMs to address issues in social media usage,we must adopt a cautious and ethical approach,being vigilant of the potential adverse effects that LLMs may have in addressing problematic social media use to better harness technology to serve individuals and society.

文摘Background:Weight-related self-stigma(WRSS)is prevalent among individuals with different types of weight status and is associated with a range of negative health outcomes.Social support and coping models explain how individuals may use different coping methods to deal with their mental health needs.Psychological distress(e.g.,depression and stress)could lead to overuse of social media and smartphones.When using social media or smartphones,individuals are likely to be exposed to negative comments regarding weight/shape/size posted on the social media.Consequently,individuals who experience problematic social media use(PSMU)or problematic smartphone use(PSPU)may develop WRSS.Therefore,the present study examined the roles of PSMU and PSPU as mediators in the relationship between psychological distress and WRSS.Methods:Using convenience sampling via an online survey,622 participants with a mean age of 23.70 years(SD=4.33)completed questions assessing sociodemographic variables,psychological distress,PSMU,PSPU,WRSS,and self-reported weight and height.Results:The hierarchical regression models showed that sex(β=0.08,p=0.01),BMI(β=0.39,p<0.001),depression(β=0.21,p=0.001),stress(β=0.18,p=0.01),PSMU(β=0.09,p=0.045),and PSPU(β=0.14,p=0.001)were significant factors for WRSS.Conclusion:The mediation models showed that both PSMU and PSPU were significant mediators in the relationships between depression and stress with WRSS.The present findings provide some evidence for understanding WRSS and has important implications for developing interventions to reduce its negative impact on individuals’health and well-being.

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Background Few studies have investigated which factors were related to adolescents'social media use.This study aimed to evaluate which factors were associated with heavy social media use on weekdays and weekends among 13-year-old adolescents.Methods We analyzed data from 3727 children from the Generation R Study,a population-based cohort study in the Neth-erlands.Associations of demographic factors(child age,sex,ethnic background,and family situation),socioeconomic posi-tion(parental educational level,parental employment status,and net household income),screen-based behaviors(computer playing and TV viewing),and the home environment(communication,supervision,and restriction)with adolescents'heavy social media use(≥2 hours/day)were assessed separately on weekdays and weekends.Multivariate logistic regression analysis was applied.Results The prevalence of heavy social media use was 37.7%on a weekday and 59.6%on a weekend day.Being a girl,liv-ing in a one-parent family,and more time spent playing on the computer were associated with heavy social media use on weekdays and weekends(all P<0.05).Low socioeconomic position adolescents(low parental educational level and low household income)were more likely to show heavy social media use only on weekends(all P<0.05).Children whose social media use was restricted by parents on weekdays or children whose social media use was supervised by parents on weekends had lower odds of heavy social media use(all P<0.05).Conclusions Being a girl,living in a one-parent family,or having a longer computer playing time were associated with heavy social media use on weekdays and weekends.More studies are needed to understand the factors associated with heavy social media use and the impact of heavy social media use on child health.

文摘Background:This study addresses the pressing need to understand the nuanced relationship between‘mattering’—the perception of being significant to others—and problematic internet use(PIU)among university students.Unlike previous research that has primarily employed variable-centered approaches,this study first adopts a person-centered approach using Latent Profile Analysis(LPA)to identify distinct mattering profiles.Subsequently,through variable-centered analyses,these profiles are examined in relation to different types of PIU—specifically problematic social media use(PSMU)and problematic gaming(PG)—as well as adaptability.Methods:Data were collected from 3587 university students across 19 universities in China.Participants completed three mattering-related scales(General Mattering Scale,Anti-Mattering Scale,and Fear of Not Mattering Inventory),along with the Bergen Social Media Addiction Scale,the Internet Gaming Disorder Scale-Short Form,and the Nine-item Adaptability Scale.Results:A four-class model identified by LPA was optimally selected:Class 1(high general mattering,low anti-mattering,low fear of not mattering),Class 2(moderate levels),Class 3(moderate general mattering,high antimattering,high fear of not mattering),and Class 4(low general mattering,low fear of not mattering,moderate anti-mattering).Significant differences were found among these classes in both PIU types(PSMU:F=139.66,p<0.001;PG:F=162.96,p<0.001).The pattern of mean differences consistently showed:Class 3>Class 2>Class 4>Class 1.Class 3 participants demonstrated the highest likelihood of meeting the addiction criteria,Class 2 showed moderate probability,while Classes 1 and 4 exhibited lower probabilities(χ^(2)=113.38 to 408.87,all p<0.001).Additionally,Class 3 reported the lowest adaptability(F=131.67,p<0.001).Conclusion:This study reveals that the unique influence of three ways of assessing feelings of mattering and the fear of not mattering on university students’PIU at the personal level,concluding that these factors are integral to understanding PIU among this demographic.

文摘Background:Despite increasing attention to parental educational anxiety in China’s educational system,the underlying mechanisms through which this anxiety affects adolescent academic performance remain unclear.This study aims to investigate how parental educational anxiety influences academic outcomes through depression and self-efficacy while considering the role of problematic social media use in today’s digital age.Methods:Data analysis was conducted using stratified random cluster sampling techniques.Participants for this study were recruited from middle and high schools in China.The sample comprised 2579 traditional two-parent families,each consisting of a pair of parents and one child.The commencement of data collection occurred in March 2024.A range of analytical techniques was employed to examine the relationship between parental education anxiety and student academic performance,including bivariate correlations,path analysis,mediation analysis,and moderation analysis.Results:The study findings revealed that parental educational anxiety negatively predicted student academic performance(β=−0.510,t=−35.011,p<0.001).Furthermore,a significant and negative relationship was identified between student depression and self-efficacy(β=−0.179,t=−8.336,p<0.001),which was chain-mediated.Additionally,problematic social media use moderated the relationship between parental educational anxiety and student academic performance(p<0.001),with stronger negative effects at higher levels of social media use.Conclusion:This study demonstrates that parental educational anxiety has both direct and indirect negative associationswith student academic performance through complex psychological pathways.The findings reveal a sequential mediation mechanism where parental educational anxiety first influences student depression,which in turn affects self-efficacy,ultimately impacting academic performance.The strength of these relationships is notably moderated by problematic social media use,with higher levels of social media engagement amplifying the negative association between parental educational anxiety and academic outcomes.These findings illuminate the complex interplay between family dynamics,student mental health,and educational achievement in the contemporary digital age.
文摘Social media, especially among the youth, is growing exponentially in our world today as more people gain access to the internet. However, the sharp increase in social media usage has led to concerns about mental health and overall well-being. While social media can be valuable for staying connected with friends and being informed about the world, it can also bring about a multitude of problems, especially among the youth. This paper aims to examine available research on the relationship between social media and issues such as depression, anxiety, and cyberbullying among adolescents. Furthermore, it will explore how childhood maltreatment can affect how an individual interacts with social media. This paper not only explains how social media could have a negative effect on adolescents, with many of the aforementioned problems being linked to social media usage, but also how social media could also bring about some benefits. However, further research is needed to better understand the complexity of youth’s relationship with social media.
文摘This study used both the “digital divide” and “attribution theory” to analyze the propensity of social media use by disaster-prone communities. The study focused on the variables that may affect how social media is used for disaster management. Structural equation modeling (SEM) was utilized in the study to analyze the data and test the hypotheses after using a survey questionnaire to collect the data. The study’s findings show that: 1) communities that are vulnerable to disasters are less likely to use social media for disaster management, 2) personal effort and intention to use social media for disaster management are positively correlated, and 3) task complexity and intention to use social media for disaster management are negatively correlated. The study added to the body of knowledge regarding the role social media plays in disaster management.

文摘Objective:Parents may use various information sources to obtain information about sport-related concussions(SRC).This study examined SRCrelated information sources used by parents of United States middle school children(age:10-15 years).Methods:A panel of 1083 randomly selected U.S.residents,aged≥18 years and identifying as parents of middle school children,completed an online questionnaire capturing parental and child characteristics,and utilization and perceived trustworthiness of various sources of SRC-related information.Multivariable logistic regression models identified factors associated with utilizing each source.Adjusted odds ratios(OR)with 95%confidence intervals(95%CIs)excluding 1.00 were deemed significant.Results:Doctors/healthcare providers(49.9%)and other healthcare-related resources(e.g.,Centers for Disease Control and Prevention,WebMD)(37.8%)were common SRC-related information sources;64.0%of parents utilized≥1 of these sources.Both sources were considered“very”or“extremely”trustworthy for SRC-related information among parents using these sources(doctors/healthcare providers:89.8%;other healthcare-related resources:70.9%).A 10-year increase in parental age was associated with higher odds of utilizing doctors/healthcare providers(adjusted odd ratio(OR_(adjusted))=1.09,95%CI:1.02-1.16)and other healthcare-related resources(OR_(adjusted)=1.11,95%CI:1.03-1.19).The odds of utilizing doctors/healthcare providers(OR_(adjusted)=0.58,95%CI:0.40-0.84)and other healthcare-related resources(OR_(adjusted)=0.64,95%CI:0.44-0.93)were lower among parents whose middle school children had concussion histories versus the parents of children who did not have concussion histories.Conclusion:One-third of parents did not report using doctors/healthcare providers or other healthcare-related resources for SRC-related information.Factors associated with underutilization of these sources may be targets for future intervention.Continuing education for healthcare providers and educational opportunities for parents should highlight accurate and up-to-date SRC-related information.
文摘With its transcultural perspective this paper looks at how families （i.e., parents and children） talk about children＇s identity and the importance of mothers＇ homeland media for the children, who are surrounded by a global popular media culture. Both studies used similar methods： interviews, participant observation, and photo-taking. The analysis shows the complexity of identity formation and the need to apply a contextual and relational perspective when wanting to understand the roles of media in the process of forming identity. The mothers＇ homeland media is an important construction tool in the process and helps the children not only with languages but also catch up with information about peers in mothers＇ homeland.
文摘This study examines three efficacy beliefs-political self-efficacy,political collective efficacy,and knowledge sharing efficacy-as antecedents of social media use and civic engagement.Employing more than one thousand samples in Singapore,we empirically test(a)a conceptual framework that can provide an understanding of the relationship between the three types of efficacy and civic engagement and(b)the underlying mechanism through which the three types of efficacy beliefs affect civic engagement via social media.The findings suggest that knowledge sharing efficacy was found to play an important role in mediating the relationships between social media use and political self-efficacy,political collective efficacy,respectively,which,in turn,influences the social media use.
文摘The purpose of this essay is to discuss the ＂Lusophone＇＇l media system, inside the ＂Lusophone＂ migration system, from the perspective of data collected in an empirical work. For this purpose, we discuss the concept of ＂Lusophone＂ and ＂Lusophone＂ migration system, and we present the context of immigration in Portugal. The empirical work involved 14 in-depth interviews2 and started by presenting, in broad strokes, some important aspects relating to the history of ＂Lusophone＂. The analysis of the interviews was sustained in the theories of economic and political ＂world-system＂ developed by Braudel （1949） and Wallerstein （2004） and extended to the concept of migration systems of Kritz and Zlotnik （1992）. Their proposals were further developed by the Portuguese sociologist Baganha （2009） who defended the particularity of a ＂Lusophone＂ migration system. Based on those concepts, we describe the theoretical and empirical research and methodological procedures, stressing the trajectories of migration, social mobility and consumption of media and Information Communication Technologies （ICT）. We analyze the interviews, highlighting the similarities and differences, regarding the uses and consumptions of media and ICTs, between Brazilians and Finally based on the results, we discuss the characteristics the citizens from Portuguese-speaking African Countries of this ＂Lusophone＂ media system.

文摘A number of events in China in recent years have been characterized by tensions or controversies between scientists and the public, such as the p-Xylene chemical project in Xiamen, nuclear energy projects, and genetic engineering. Scientists tend to attribute such conflict to inadequate public knowledge of science, leading to misunderstandings about it. However, that view ignores the influence on public perceptions of news reports and online discussions about controversial technologies in new media. Social media reporting affects the audience's perception of the risks posed by controversial technologies and can cause people to lose confidence in the scientific community and damage their trust in government. Thus, the public opposes these technologies. In this context, this study explores the relationship between the public's trust in the scientific community and the government on the one hand and its attitude towards controversial technologies on the other. I surveyed 1,235 people using a national online probability sampling strategy. I found that people's use of new media was significantly related to the extent of their knowledge of specific controversial technologies and was associated with other people's opinions about those technologies. The more attention people paid to We Chat coverage of genetically modified organisms(GMOs), the more supportive they were of them. Thus, the public's use of new media is a key factor in predicting its positive attitude to GMOs. Scientific literacy also significantly affects public attitudes to GMOs, directly as well as indirectly.
