Toward professional standards for media transparency in the United States: Comparison of perceptions of non-transparency in national vs. regional media

This article reports the results of the national survey of 287 Public Relations Society of America members regarding current media transparency practices in the United States. The purpose of the study was to understand the forms of media non-transparency that exist in the United States, levels of non-transparency at the national and local/regional media, and perceptions of non-transparent practices by the public relations practitioners in the country. The project builds on previous research on global media transparency (Tsetsura & Kruckeberg, 2011) and uses Tsetsura’s (2005) framework to study media transparency. The survey results showed that direct media bribery is not a pressing issue in the United States; however, indirect media pressures that involve new forms of content creation, including native advertising and content marketing, are worrisome. Specifically, forms of indirect media bribery are common at the local and regional media levels in the USA. Research findings demonstrate that U.S. practitioners experience particular non-transparent challenges when working with the media and recognize financial pressures that U.S. media outlets face today.The results provide a basis for creating standards in U.S. practice to ensure that new forms of content creation, including native advertising and content marketing, are not acceptable at any level when sources of content are not disclosed. The study concludes with the discussion about the importance of understanding how new forms of sponsored content relate to media transparency in the USA and why U.S. practitioners should understand how media non-transparency relates to the issues of native advertising and brand journalism.     

储层岩石矿物成分对酸蚀裂缝导流能力的影响

储层岩石矿物成分是酸压改造效果影响因素之一。研究认为，在储层岩石矿物成分中易溶物的含量及分布方式决定了酸蚀裂缝导流能力大小，易溶蚀物的含量越多，岩石溶蚀速率越快。室内测试了不同溶蚀速率下的灰岩和白云岩的酸蚀裂缝导流能力，研究了岩石溶蚀速率、易溶蚀物含量对酸蚀裂缝导流能力的影响，对酸压工艺设计方案提出了指导性建议。研究结果表明，储层岩石溶蚀速率与酸蚀裂缝导流能力增加倍比存在抛物线关系，易溶蚀物占30%40% 时酸蚀裂缝导流能力保持较好。

Distributed intervention: networked content moderation in anonymous mobile spaces

Given recent public focus on the use of digital tools to engage in discrimination and harassment, online platforms have come under increasing scrutiny to address online incivility. Many of these efforts have been critiqued for relying too heavily on technical tools or burdening individuals with the responsibility for reporting inappropriate actions. This research examines practices of digital bystander intervention on the anonymous localized mobile app Yik Yak. Through an analysis of the firsthand experiences of college students in the United States, this research identifies and investigates practices of networked intervention—that is, strategies of content moderation where success relies on collective action. Rooted in a general uncertainty and skepticism regarding reporting tools provided by the platform, findings suggest a preference for intervention practices that depend on distributed responsibility and networked activity. Taking inspiration from research on college bathroom graffiti—a parallel discursive environment—this paper employs the feminist theory of relational autonomy to explore the possibilities and limitations of networked intervention to cultivate individual and collective empowerment.     

‘Warren Buffet is my cousin’: shaping public understanding of big data biotechnology,direct-to-consumer genomics,and 23andMe on Twitter

Scholars, educators, regulators, pundits, and other observers are advocating for regulation and oversight of direct-to-consumer (DTC) genomic testing. As a result, the technology has been subject of highly visible public and regulatory controversy. In this article, we explore the nature and the shape of the sentiment of public discourse about the DTC company, 23andMe. We conduct a quantitative content analysis and qualitative framing analysis on Tweets. We find that the discourse surrounding DTC genomics and 23andMe is largely positive. We also identify a number of frames users deploy to debate, discuss, and share their experiences with DTC genomics and 23andMe. We argue that these frames create meaning around this emerging technology for its users.     

How Have Other Journals Compared to “The Top Seven” Journals in Family Social Science with Respect to LGBT-Related Research and Reviews? A Comment on “A Content Analysis of LGBT Research in Top Family Journals 2000–2015”? An Editorial Analysis

Van Eeden-Moorefield, Few-Demo, Benson, Bible, and Lummer (2018) recently reviewed the content of seven family social science journals with respect to theory and methods used in 153 articles featuring LGBT research or reviews of LGBT research. They concluded that less than three percent of 6,832 articles published in those journals between 2000 and 2015 were LGBT-related and that most had not used explicit theory and had used purposive cross-sectional samples consisting mostly of White and middle-class participants. During the tenure of the present editor, between 2010 and 2017, Marriage & Family Review featured 14 research reports, reviews, or commentary on LGBT-related issues out of 250 articles, not counting brief editorials or biographies between 2010 and 2017, an odds ratio of over 2.0 compared to the other “top-tier” journals. Likewise, the Journal of Family Theory & Review published at least 15 articles, mainly reviews or commentaries, on LGBT-related issues between 2009 and 2017. Articles in Marriage & Family Review and Journal of Family Theory & Review were more likely to be reviews of the literature, or feature explicit theory, to be qualitative in methodology, or to involve interviews or surveys, while other characteristics were similar to those in the other seven journals. Thus, even if some mainstream family journals did not publish often on LGBT-related issues, other important family science journals have done so. Furthermore, there are numerous scholarly journals that welcome LGBT-related research and reviews almost exclusively.     

Exploring gaps between MSW students’ experiences and expectations of field supervision in a Chinese setting

The quality of field supervision is essential to prepare social work students for professional practice. This qualitative study explored the experiences and expectations of 22 MSW students who received their field supervision at social work professional organizations in mainland China. Findings indicate that there are significant differences between the actual supervision that students received and their expectations with regard to the structure and content of supervision. This study contributes to the literature by clarifying further what the lack of time for supervision and the lack of professional supervision mean in China’s context.
