Displacement or complementarity? Assessing the relationship between social media and public library usage in the U.S., South Korea,and Singapore

The relevancy of public libraries is often called into question, with some saying that library services have been or will be displaced by, among other things, new media such as social media. This study tested this displacement hypothesis with survey data collected from three nations (the U.S.: N = 879; South Korea: N = 700; and Singapore: N = 987). Ordinal regressions were used to investigate the relationship between the use of social media and nine public library services, taking into account individual demographic differences. The results show that for all three nations, social media use has significant complementary relationships with all nine library services examined. Computer and information literacy training showed the largest effect size. However, signs of displacement effects were observed in the odds ratio statistics, particularly among daily social media users and in reference services, library visits, and time spent in the library, suggesting that where displacement is concerned, these areas warrant extra attention.     

Which candidates do the public discuss online in an election campaign?: The use of social media by 2012 presidential candidates and its impact on candidate salience

The effects of new communication technologies on election campaigns, and the effectiveness of media-centered campaign strategies more broadly, remain ongoing subjects for debate in political science. This study provides some of the first empirical evidence about the potential impact of social media on the 2012 U.S. presidential elections, by testing the association between “candidate salience” and the candidates' level of engagement in online social media sphere. We define “candidate salience” as the extent to which candidates are discussed online by the public in an election campaign, and have selected the number of mentions presidential candidates receive on the social media site, Twitter, as means of quantifying their salience. This strategy allows us to examine whether social media, which is widely recognized as disruptive in the broader economic and social domains, has the potential to change the traditional dynamics of U.S. election campaigns. We find that while social media does substantially expand the possible modes and methods of election campaigning, high levels of social media activity on the part of presidential candidates have, as of yet, resulted in minimal effects on the amount of public attention they receive online.
