Online Celebrity Bashing: Wrecking Ball or Good for You? Adolescent Girls’ Attitudes Toward the Media and Public Bashing of Miley Cyrus and Selena Gomez

Journalists and readers of celebrity news regularly bash celebrities online, a behavior that is easily accepted among adolescents. This study investigates whether these attitudes of acceptance differ according to the perpetrator of the bashing (media versus public) and the likeability of the involved celebrity (liked versus disliked). Using a vignette study, we examine adolescent girls’ attitudes toward media (journalists’) and public (readers’) bashing of a generally disliked celebrity (Miley Cyrus) and a generally liked celebrity (Selena Gomez). All participants read an identical negative news story (media bashing) and two related negative reader comments (public bashing). Participants were randomly assigned to read this information about either Miley Cyrus or Selena Gomez. Results of a mixed-design ANOVA showed that the girls had less negative attitudes toward media bashing compared with public bashing. Moreover, they more easily accepted the bashing of a disliked celebrity than the bashing of a liked celebrity.     

Out of Sight, (Not Yet) Out of Mind: The Impact of Tie Strength on Direct Interaction and Social Surveillance Among Geographically Close and Long-Distance Facebook Friends

Social networking sites are considered a valuable resource to maintain existing friendships even over considerable distances. The present study emphasizes tie strength as a crucial determinant for the use of interactive and passive features among 302 active Facebook users and friends of different relational closeness (close friends vs. casual friends vs. acquaintances) as well as a moderator for the impact of physical distance. As expected, tie strength affected direct interaction linearly, whereas social surveillance followed a quadratic trend. Furthermore, moderation analyses revealed less frequent direct interaction between close friends and stronger surveillance of casual friends’ profiles as physical distance increases. These results indicate different functions in relationship maintenance for both behaviors as direct interaction aims at nurturing current relationships, while surveillance serves as a catalyst for promising future communications. As a consequence, physical distance influences direct interaction adversely due to emerging constraints but also contains informational value encouraging information-seeking behaviors.     

Investigating the Role of Problem Severity and Channel Publicness on the Sophistication of Support-Seeking Messages on Social Network Sites: A Replication Study

Oh and LaRose (2016) contended that problem severity and channel publicness shape support seekers’ goals, time spent composing messages, and the sophistication of those messages. The current study seeks to replicate and extend Oh and LaRose’s study to produce a more accurate understanding of the factors that influence the sophistication of support-seeking messages online. Support seekers’ goals varied according to the severity of a stressor and the publicness of a channel, and the amount of time people spent composing a message influenced its sophistication. We extend the original study by examining associations that were not initially tested. Time spent composing messages mediated the influence of problem severity on the quality of people’s messages, and this effect was moderated by channel publicness.     

Two Thousand Students,One Librarian: Balancing Depth and Breadth of Library Instruction for Online Graduate Students

Many librarians struggle with how to balance scalable instructional offerings with more personalized instruction for online students—scale tends to come at the cost of personalization and vice versa. This paper will discuss three methods for connecting with online students that range from one-to-one personalization to widely scalable instruction: individual consultations, scaffolded instructional webinars, and asynchronous video tutorials. The student engagement with each type of instruction will be discussed, with ideas for future directions provided.     

Contesting Communities

This introductory article to the combined special issue of Journalism Studies and Journalism Practice provides an overview of some of the key contemporary approaches to studying journalism and social order. It argues the need to step beyond a functionalist framework when considering the news media’s central role in shaping social connections, community and cohesion. To advance our understandings of social order, our paper suggests a greater emphasis of the significance of journalism’s relationship to the wider social sphere along with three other key considerations, including (1) a critical focus on the relationship between media, politics and social order, especially in defining and/or negotiating “anti-social” practices and social disintegration; (2) a more refined focus on the “imagined” and geographic boundaries of news audiences in digital spaces; and (3) the changing relationship to norms and conventions of journalism practice from trust and legitimacy to the role of journalists as arbiters and connectors across social spaces.     

Community differences in the implementation of Strong Communities for Children

In 1993, the U.S. Advisory Board on Child Abuse and Neglect recommended a neighborhood-based strategy to prevent child abuse and neglect. The Board further recommended the development of Prevention Zones to allow for testing of the effectiveness of community-wide child protection efforts in neighborhoods of differing population density, ethnic and cultural composition, and social and economic resources. Following the Board's recommendation, this article presents the results of a trial of the effectiveness of a neighborhood-based strategy in low- and high-resource communities. Using management, survey, and administrative data, the research showed that both community types experienced declines in founded cases of and injuries suggesting child maltreatment for children under age 5. Low-resource communities experienced greater levels of mobilization, as measured by community and institutional engagement, and a greater number of positive outcomes related to changes in the quality of life for families and community norms relative to child and family well-being. In particular, the low-resource communities experienced the largest increases in receiving help from neighbors, neighboring, perceived household safety for neighborhood children, and observed positive parenting. High-resource communities experienced greater increases in intermediate outcomes related to self-reported parenting practices. The findings suggest that, ultimately, community mobilization can occur and be an effective means of preventing child maltreatment across community types. It appears, however, that community mobilization may play a more significant role in low-resource communities.

If Only They Knew: Audience Expectations and Actual Sourcing Practices in Online Journalism

ABSTRACT

This article answers the question “Are the sourcing practices in Finnish online journalism trustworthy?” Here, trustworthiness is operationalized as the fulfillment of audience expectations towards sourcing practices. To this end, expectations of young Finnish adults (aged 18–28) were compared to the observed practices of Finnish online journalists. A total of 36 news items (from 12 journalists working in three newsrooms, published in 2013 and 2017) were analyzed. The analysis indicates that online journalists’ sourcing practices largely do not conform to this audience segment's expectations. Namely, the audience expects more comprehensive investigation and thorough verification than what is common practice in online journalism. The use of high-credibility sources is both expected and commonplace. The results imply that transparency may be harmful rather than beneficial to journalism's credibility, as the unveiled practices do not always meet audience expectations.
