Analysis of Academic Libraries' Facebook Posts: Text and Data Analytics     

Sultan M. Al-Daihani  Alan Abrahams 《The Journal of Academic Librarianship》2018,44(2):216-225

This research analyzed a dataset of academic libraries' posts on Facebook. It applied a text and data analytics approach to a dataset collected from the Facebook posts of academic libraries at the top 100 English-speaking universities, as listed by the 2014 Shanghai World University Rankings. The dataset is from a two-year posting history of 18,333 unique posts, 113,621 likes, and 3401 comments. Less than a quarter of the libraries had more than 2000 post-related likes, and only seven received more than 100 comments on their postings. Content analysis identified the most prevalent single word (unigrams), bigrams (two-word sequences), and trigrams (three-word sequences) in high and low engagement content. Semantic analysis identified the semantic categories for posts with high and low engagement. The findings can assist academic libraries in their social media strategies for engagement, marketing, and visibility.  相似文献   

Build It and They Will Come? Patron Engagement Via Twitter at Historically Black College and University Libraries     

Brenton Stewart  Jessie Walker 《The Journal of Academic Librarianship》2018,44(1):118-124

This study is a social media analysis on the use of Twitter at Historically Black Colleges and University (HBCU) libraries. While information science researchers have begun examining how libraries use social media, the vast majority of these studies are situated at large flagship research-intensive universities. Additionally, there currently exist deficiencies in research on social media deployment at HBCU libraries. We leverage, the IBM Watson's analytic engine, to systemically examine over 23,000, tweets over an eighteen-month period, around a set of objective measures including propagation of retweets and sentiment to assess follower engagement. The analysis found little evidence of follower engagement with library generated content. However, we observed a substantial volume of library tweets coalesced around institutional boosterism, rather than library related phenomena. This non-library related content represented the vast majority of retweets, but paradoxically was propagated by non-followers. Additionally, tweets relating to institutional boosterism produced the most positive sentiment within the data.  相似文献   

They’re good blogs,Brent: (Mostly) painless branding for information professionals     

Sarah E. McFadden 《Public Library Quarterly》2018,37(3):306-317

ABSTRACT

Social media is a powerful tool for building an online presence, but it asks a lot. While it affords plentiful opportunities for professional development and networking, building a professional brand in an online space is not without its drawbacks and risks. By working from a set of actionable principles and benchmarks, users can minimize frustrations and setbacks to build a useful professional presence, all while imbuing the web with the tenets of good information stewardship.  相似文献   

More Than Just a Student Voice: Facilitating Student Leadership Development Through the Library Student Liaison Program     

Suzanne Milton  Qing H. Meade 《图书馆管理杂志》2018,58(4):346-363

This article explores how the library-student liaison program at Eastern Washington University (EWU) Libraries has evolved into an opportunity for students to develop leadership skills. Originally designed to foster better communication between the EWU Libraries and students enrolled at the university, we recognized that the process of achieving established goals for the program provided a vehicle for students' leadership-skill development. To facilitate the leadership process, librarians employed the Social Change Model. Designed specifically for college students, this model engages the student to develop individual capacities to strengthen group activities that foster positive changes in the community and society.  相似文献

The Constitutive Relationship of Social Communication Competence to Self-Compassion and Hope     

Laura R. Umphrey  John C. Sherblom 《Communication Research Reports》2018,35(1):22-32

Communication is constitutive—in theory. In research, however, communication is often treated as an outcome, influenced by personal attributes. The present research examines social communication competence as a constitutive influence predicting self-compassion and hope. Path analysis results support this hypothesis. Results show that social communication expressivity (β = .14), sensitivity (β = –.32), and control (β = .20) predict self-compassion. Social communication sensitivity (β = .26) and control (β = .27) affect hope agency, and social communication control (β = .29) predicts hope pathways thinking. These results provide evidence of the constitutive nature of communication.  相似文献   

Why Users Share the News: A Theory of Reasoned Action-Based Study on the Antecedents of News-Sharing Behavior     

Veronika Karnowski  Larissa Leonhard  Anna Sophie Kümpel 《Communication Research Reports》2018,35(2):91-100

Social media have become an integral part of online news use, affecting how individuals find, consume, and share news. By applying the Theory of Reasoned Action (TRA), this study investigates the effects of motives, attitude, and intention on news-sharing behavior among German social media users (n = 333). Findings show that news-sharing attitude and subjective norms have a positive effect on news-sharing intention, which in turn has a positive effect on actual news-sharing behavior. Taken together, we see that a new media behavior in the early phases of its societal diffusion—like social media news sharing in Germany in 2015—can mainly be explained by a rational choice logic and is rooted in the motives of socializing and information seeking. This finding thus reflects the double nature of social media as a means for both information retrieval and social grooming.  相似文献   

A Model for Quantitatively Analyzing Representations of Social Class in Screen Media     

Elizabeth Behm-Morawitz  Brandon M. Miller  Jennifer Lewallen 《Communication Research Reports》2018,35(3):210-221

Content analyses of prime-time television provide a picture of predominant cultural stereotypes and social trends. The present research is a quantitative content analysis of social class in popular broadcast and cable television in the United States. This research advances scholarship by systematically analyzing character class in addition to more commonly examined variables such as race and gender. A model for the operationalization of class for quantitative content analyses of mediated texts is offered. This proof of concept study demonstrates the viability of studying media representations of class quantitatively to systematically document patterns of portrayal.  相似文献   

Social Comparisons and Need Fulfillment: Interpreting Video Game Enjoyment in the Context of Leaderboards     

John A. Velez  David R. Ewoldsen  Michael D. Hanus  Hyunjin Song  Jonathan A. Villarreal 《Communication Research Reports》2018,35(5):424-433

This study examines how social comparison information provided by video game leaderboards may influence players’ retrospective judgments of autonomy, competence, and relatedness need fulfillment. Participants played a video game and were randomly assigned to receive no postgame feedback or were shown a leaderboard that placed them in the top or bottom quartile of players. Results indicate downward social comparisons increase enjoyment by increasing competence and relatedness perceptions. However, upward comparisons did not have an opposite effect, nor did either type of social comparison influence players’ autonomy perceptions. Implications for applying Self-Determination Theory to video game enjoyment in the context of social comparison feedback is discussed.  相似文献
