This paper discusses the importance of ascribing cognitive authority to Internet information, provides basic evaluative criteria for ascribing authority, and describes technical tools for investigating authorship and conducting more advanced research. The proffered tools offer ways to investigate authorship and identity and can significantly contribute to the confidence with which a researcher can ascribe authority. Analyses of the output from technical tools directly reveal how these tools may be used to draw conclusions regarding authorship and identity. An overview of public‐key infrastructure (PKI) is provided as a possible solution to the problem of determining identity in a networked environment.

This paper discusses facilitated Internet evaluation, explores heuristics, tools and systems that have been developed to help users evaluate Internet information. Delineates a taxonomy for these systems, and offers descriptive information and sample tools representative of each category.

The purpose of this paper is to examine the role of one particular online discussion forum as a potentially authoritative health information source for its users. The concept of cognitive authority is used as a starting point for understanding information evaluation in this context. The focus is placed on the types of information users seek for from this forum, the ways they assess the credibility of information obtained, and their views on the impact of this information.

The empirical data were collected with a questionnaire survey from the users of a Finnish online forum for girls and young women (n=290). The data were analyzed qualitatively with content analytic techniques and quantitatively by using descriptive analysis.

The forum was found to offer girls and young women the possibility to receive health information from peers. It was viewed as an appropriate source for experiential rather than factual health information and used to find information on sexuality, bodily functions and diets, for example. Author-related cues, argumentation and tone, veracity and verification were recognized as means to evaluate information credibility. Credibility evaluation was found to be linked with conceptions of the forum and the type of information sought. A share of the respondents recognized the information obtained to have influence on their thinking or behavior.

Based on the findings, it can be argued that the members of the online forum – individually or collectively – can act as cognitive authorities for other users. The findings cannot be generalized beyond this online forum, to Finnish girls or young women, or even the users of the online forum. However, they provide insights into the ways young people evaluate user-generated information in a particular online setting and domain of knowledge and as such contribute to research on cognitive authority, credibility evaluation and information literacy.

An experimental study of the mechanical behavior of fused‐deposition (FD) ABS plastic materials is described. Elastic moduli and strength values are determined for the ABS monofilament feedstock and various unidirectional FD‐ABS materials. The results show a reduction of 11 to 37 per cent in modulus and 22 to 57 per cent in strength for FD‐ABS materials relative to the ABS monofilament. These reductions occur due to the presence of voids and a loss of molecular orientation during the FD extrusion process. The results can be used to benchmark computational models for stiffness and strength as a function of the processing parameters for use in computationally optimizing the mechanical performance of FD‐ABS materials in functional applications.

Aims to present a critical appraisal of the research relating to the sources of stress and stress reactions experienced by women managers. Considers the available data and level of understanding, and the assumptions that traditional approaches have been based upon. Presents conflicting findings and considers the implications of such results. Offers an overview of the current knowledge pertaining to women and managerial stress, raising a number of questions for which there are currently no answers.

This article presents an annotated bibliography of literature recently on library instruction and information literacy in academic, school, public, special, and all types of libraries. Interest in the topic remains strong, with a growing number of pieces also including the importance of assessment. Other themes discussed in the articles include research, collaboration, the use of tutorials, tours, distance learning, active learning, problem‐based learning, and the role of accreditation bodies.

This study aims to adopt a cognitive heuristic approach to investigate the interaction effect of a message source characteristic (reviewer expertise [RE]) and two message structure characteristics (review rating consistency [RC] and review valence [RV]) on the perceived credibility of hotel online reviews.

Data were collected from 242 university students and were analyzed by three-way analysis of variance through a 2 × 2 factorial experiments using a simulated hotel review page on TripAdvisor.

Results show a three-way interaction effect of RE, RC and RV on the perceived credibility of hotel online reviews. The main effects of the three factors are also determined. Higher perceived credibility scores are found for negative reviews, reviews written by experts and reviews with a consistent rating.

This study adopts an experimental approach and is the first to investigate the three-way interactions of message source and message structure characteristics of online hotel reviews. Data were collected from students in a university in Hong Kong. Results may not be generalizable to other markets.

Results suggest that reviews written by experts have higher perceived credibility. Hotels should pay attention to the content of online reviews and the expertise level of reviewers. Efforts should be exerted to create positive experiences for hotel guests that motivate expert reviewers to write positive reviews. Note that negative reviews have higher perceived credibility than positive ones. Hotels should promptly address negative reviews and provide professional responses to reviewers. Platform operators of user-generated content (UGC) should create well-defined reviewer profiles that can serve as cues that communicate the different expertise of reviewers.

This study is the first to test the three-way interaction effect of RE, RC and RV on the perceived credibility of hotel online reviews. Results provide recommendations to hotels and UGC operators and enable them to benefit from emerging UGC usage.

This paper aims to present recently published resources on library instruction and information literacy providing an introductory overview and a selected annotated bibliography of publications covering all library types.

This paper introduces and annotates English-language periodical articles, monographs, dissertations, reports and other materials on library instruction and information literacy published in 2018.

The paper provides a brief description of all 422 sources, and highlights sources that contain unique or significant scholarly contributions.

The information may be used by librarians and anyone interested as a quick reference to literature on library instruction and information literacy.

The purpose of this paper is to present the results of a study that explored public perceptions of the credibility of “facts and figures” contained within five social media posts produced by political parties in Scotland.

The study consisted of an online survey conducted in Spring 2017 (n=538). Respondents were asked to gauge the reliability of “facts” contained within the posts, to provide reasons for their answers, and to indicate how they might go about confirming or debunking the figures.

Less than half the sample believed the posts’ content would be reliable. Credibility perceptions were influenced by various factors, including: a lack of cited sources; concerns about bias or spin; a lack of detail, definitions or contextual information; personal political allegiance and trust; negative campaign techniques; personal experience of policy issues; and more intuitive judgements. Only small numbers admitted that they would not know how to find out more about the issues or would be disinclined to look further. The majority appeared confident in their own abilities to find further information, yet were vague in describing their search strategies.

Relatively little empirical research has been conducted exploring the perceived credibility of political or government information online. It is believed that this is the first such study to have specifically investigated the Scottish political arena.
