“Tightening the Knots” of the International Drugs Trade in Brazil

Much academic analysis of media representations of drugs-related violence in Brazil has focused on their role in perpetuating violence and societal divisions. There is less research on how the country’s traditional news media can shape information in order to foster dialogue between people and potentially resolve conflict. This article aims to address this gap by exploring the possibilities and challenges for printed news media to acquire “mediated” social capital. The concept is understood here as a specific resource of power that has the potential to connect people from diverse social, cultural and economic backgrounds. In order to do so, we analyse how a popular Rio newspaper has used its symbolic power to produce social capital with an investigative series about Brazil’s involvement in the international drugs trade. It is argued here that the series paints a complex picture of its causes and consequences and is an important step towards a deliberative process about possible solutions to drugs-related violence in Rio and beyond.     

Beyond “J-Tweeters”

Based on a survey (N?=?1613) directed to members of the Norwegian Journalist Association (NJ), this paper presents an extensive overview of the ways in which comparably older and newer online platforms have been incorporated into the professional lives of Norwegian journalists. While plenty of research is available that explores the uses of Twitter by journalists, the results presented here suggest that Facebook is by far the most frequently used platform throughout the journalistic process—from collecting information, distributing content and engaging with readers. Statistical analyses provide further insights into which variables appear to influence certain modes of usage across the studied platforms. Based on the results, the argument is made that the advantages of using Facebook as a platform for journalistic practices are obvious due to its popularity among the general public, but that this utilization of one platform over others also could be problematic. As Facebook continues to gain leverage towards the newspapers they host, questions of journalistic practices need to come to the fore.     

“I’m Really Confident I Can Find the Exact IKEA Pillow”: A Qualitative Look at the Search Self-Efficacy of Graduating MLIS Students

Abstract

There is limited qualitative research on the information-seeking self-efficacy (SE) of library and information science (LIS) graduate students. This study examines graduating LIS students’ experiences with information seeking, including experiences in the LIS program that led to increased levels of information-seeking SE and specific recollections of moments when SE increased. Many students identified similar factors as key to developing SE, including education-related assignments, library work experience, LIS internships, and specific LIS coursework. Because of the small sample size, further research would help to identify additional factors that promote LIS students’ information-seeking SE.     

Economies of reputation: the case of revenge porn

Revenge porn involves publicly releasing pictures of a person’s sexual activity, along with the means to contact that person, to provoke widespread shaming. This paper analyzes the US-based revenge porn website MyEx.com through discourse, legal, and information network analyses. The paper explores how revenge porn is not only an instance of online sexual violence rooted in abjection but also symptomatic of a new political economy of subjectivity, where both the human-based and the automated, algorithm-based circulation of personal information are at the center of processes through which the self is seen and valued, both socially and economically, by others.     

Boosting multi-label hierarchical text categorization

Hierarchical Text Categorization (HTC) is the task of generating (usually by means of supervised learning algorithms) text classifiers that operate on hierarchically structured classification schemes. Notwithstanding the fact that most large-sized classification schemes for text have a hierarchical structure, so far the attention of text classification researchers has mostly focused on algorithms for “flat” classification, i.e. algorithms that operate on non-hierarchical classification schemes. These algorithms, once applied to a hierarchical classification problem, are not capable of taking advantage of the information inherent in the class hierarchy, and may thus be suboptimal, in terms of efficiency and/or effectiveness. In this paper we propose TreeBoost.MH, a multi-label HTC algorithm consisting of a hierarchical variant of AdaBoost.MH, a very well-known member of the family of “boosting” learning algorithms. TreeBoost.MH embodies several intuitions that had arisen before within HTC: e.g. the intuitions that both feature selection and the selection of negative training examples should be performed “locally”, i.e. by paying attention to the topology of the classification scheme. It also embodies the novel intuition that the weight distribution that boosting algorithms update at every boosting round should likewise be updated “locally”. All these intuitions are embodied within TreeBoost.MH in an elegant and simple way, i.e. by defining TreeBoost.MH as a recursive algorithm that uses AdaBoost.MH as its base step, and that recurs over the tree structure. We present the results of experimenting TreeBoost.MH on three HTC benchmarks, and discuss analytically its computational cost.

Putting the U in carbon capture and storage: rhetorical boundary negotiation within the CCS/CCUS scientific community

This paper examines responses to a framing shift from carbon capture and storage (CCS) to carbon capture, utilization, and storage (CCUS) within science and engineering professionals’ communication. We argue that the framing shift is a breach in the rhetorical boundaries of the CCS professional community that calls forth negotiation through responses that proactively support, resist, or acquiesce. This study offers a heuristic for examining scientific framing in expert-to-expert internal scientific rhetoric. It also contributes to contemporary research on the intersection of rhetoric of science and science, technology, and society; the social dimensions of CCS; energy communication; and applied communicative practices in scientific communities.     

Supportive Communication and the Adequate Paraphrase

The active listening paradigm recommends that helpers paraphrase the thoughts and feelings of support seekers. But how? This study compared evaluations of four types of paraphrase messages derived from the work of Polanyi. Results showed that certain forms of paraphrasing are evaluated as more helpful, sensitive, and supportive than others, though differences were not in full alignment with theoretical predictions, and results were dependent on narrative prompt. Our study provides initial empirical data that question the practical advice given to informal help providers found in our academic scholarship and textbooks. Formal and informal helping relationships have many similarities and differences that should be acknowledged and tested with a variety of methods and populations.     

Partnering with the Public Library for Health Care Education: An Evaluation of Affordable Care Act Messages

Despite implementation of most of the provisions of the Affordable Care Act (ACA) by 2014, the public still has questions about the health care law. To assess the potential of using the library as a hub for ACA education, we tested existing and new culturally relevant messages about the health care law with twenty-seven community members. Participants discussed the message prototypes, including the visual components and promotional content, and provided advice to modify content and design to best reach target audiences. Future research can follow this example to engage libraries and community members in developing and evaluating culturally relevant health messages.
