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

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
