Social media campaigns,electoral momentum,and vote shares: evidence from the 2016 Hong Kong Legislative Council election

By studying candidates’ Facebook fan pages and rolling poll data during the Hong Kong Legislative Council election in 2016, this article aims at examining the relationships between candidates’ campaign performance on social media, electoral momentum, and vote shares. We contend that, under specific contextual conditions, social media campaigns could affect candidates’ momentum during the election period, which can in turn affect vote shares. We also examine how the relationships between social media performance and electoral momentum vary according to the candidates’ background characteristics, including age, political affiliation, incumbency status, and scale of the campaign of the political group to which the candidates belong. The results show that candidates’ social media performance can indeed predict vote shares indirectly via the mediation of electoral momentum. The predictive power of social media performance is stronger for pro-democracy candidates, incumbents, and candidates belonging to political groups with larger election campaigns.     

When off-line seeks information online: The effect of modality switching and time on attributional confidence and social attraction

This study’s goal was to learn how adding the extractive information-seeking behavior of Facebook profile viewing following face-to-face information-seeking behavior in initial interactions affected attributional confidence (AC) and social attraction (SA). Additionally, the present study was a quasi-replication of research exploring how changes in time spent on information seeking impacted AC and SA testing two uncertainty reduction theory axioms. Two modalities, face-to-face (FtF) only versus FtF and profile viewing, across three time conditions of 4, 6, and 8 minutes yielded six experimental conditions. AC for the two modalities were similar when time was held constant. Comparing the two modalities for 8 minutes resulted in higher social attraction for the FtF-only condition. Also, the data report a significant interaction with modality and time. Time impacts AC and SA even with relatively small changes.     

Automatic and conscious context effects in average and advanced readers

Average and advanced readers from the fourth and sixth grades read visually presented words as rapidly as possible. Target words were preceded by a related prime word, an unrelated word, or a neutral warning stimulus. Related trials constituted 75% of the word prime trials for half of the subjects in each group, and only 25% for the other half. All groups were sensitive to this proportion manipulation, showing only faster naming times for related targets in the 25% condition. In the 75% condition, subjects showed inhibition for unrelated targets, as well as facilitation for related targets. The results indicate that the ability to use context deliberately to facilitate word recognition reaches asymptote for the average reader by the sixth grade at the latest, and perhaps by the fourth. This ability does not appear to be one that shows further improvements at higher levels of reading skill. Some possible reasons for the discrepancies between this research and that using incomplete sentence contexts are considered.     

True directed forgetting in pigeons may occur only when alternative working memory is required on forget-cue trials

Results of directed-forgetting research with pigeons are difficult to interpret because of alternative nonmemorial accounts of performance decrements and important procedural differences from comparable research with humans. Prior research has noted the absence of directed forgetting when artifacts have been removed (e.g., nonreward following forget cues and differences in response patterns on remember and forget trials in training). In this article, it is argued that, in human directed-forgetting research, presentation of a forget cue allows for the reallocation of memory maintenance to items to be remembered. In the present experiment, true directed forgetting is found when nonmemorial performance decrements are eliminated and forget cues allow for the reallocation of sample memory to test-relevant cues.     

Relative Success? Determinants of College Graduation Rates in Public and Private Colleges in the U.S.

Amid growing criticism of public universities, there is little discussion of what appropriate institutional evaluation would entail. Six-year graduation rates are commonly used, and public bachelors granting institutions have lower rates than private institutions, but with the growth in non-traditional college attendance, these can be misleading. We develop a regression analysis as a way to evaluate institutions serving vastly different populations. We do this with a dataset constructed from publicly available sources and focus on the evaluation of public colleges. We show that public colleges are able to do more with less: our models suggest that with equivalent resources and student populations, public schools would graduate a slightly larger percentage of students than privates. Since financial resources come from very different sources, we evaluate this finding closely.     

News Sources and Follow-up Communication

For sports actors, social media provide the opportunity to bypass sports journalism's gatekeeping function and to disseminate sports-related information to target groups directly. Thus, social media have been conceptualized as a competitor to journalism. We argue that the relation is much more diverse. We differentiate between competitive, integrative, and complementary facets of the relationship between sports journalism and social media. Our study focuses on complementarity and analyzes how far social and mainstream media serve as sources for each other. Therefore, we combine an online survey among 122 German sports journalists, an analysis of the Twitter networks of German sports journalists during the Winter Olympics 2014, and a content analysis of the most popular news items in social media. Results suggest that sports journalists perceive social media accounts of athletes as beneficial news sources, especially to gather inside information. Huge sports events influence the social media activities of sports journalists as they tend to have stronger connections to athletes at these times. Whereas social media appear to be significant sources for sports journalism, sports media content receives little attention in social media. However, our results indicate that sports journalism and social media indeed maintain a complementary relation.
