Adding dimensions to the analysis of the quality of health information of websites returned by Google. Cluster analysis identifies patterns of websites according to their classification and the type of intervention described.

Background and aims: Most of the instruments used to assess the quality of health information on the Web (e.g. the JAMA criteria) only analyze one dimension of information quality, trustworthiness. We try to compare these characteristics with the type of treatments the website describe, whether evidence-based medicine or note, and correlate this with the established criteria. Methods: We searched Google for “migraine cure” and analyzed the first 200 websites for: 1) JAMA criteria (authorship, attribution, disclosure, currency); 2) class of websites (commercial, health portals, professional, patient groups, no-profit); and 3) type of intervention described (approved drugs, alternative medicine, food, procedures, lifestyle, drugs still at the research stage). We used hierarchical cluster analysis to assess associations between classes of websites and types of intervention described. Subgroup analysis on the first 10 websites returned was performed. Results: Google returned health portals (44%), followed by commercial websites (31%) and journalism websites (11%). The type of intervention mentioned most often was alternative medicine (55%), followed by procedures (49%), lifestyle (42%), food (41%) and approved drugs (35%). Cluster analysis indicated that health portals are more likely to describe more than one type of treatment while commercial websites most often describe only one. The average JAMA score of commercial websites was significantly lower than for health portals or journalism websites, and this was mainly due to lack of information on the authors of the text and indication of the date the information was written. Looking at the first 10 websites from Google, commercial websites are under-represented and approved drugs over-represented. Conclusions: This approach allows the appraisal of the quality of health-related information on the Internet focusing on the type of therapies/prevention methods that are shown to the patient

Editorial

In this issue of Literacy and Numeracy Studies, Theres Bellander and Zoe Nikolaidou examine the online health literacy practices of parents whose child or unborn foetus has been diagnosed with a heart defect, and Julie Choi and Ulrike Najar report on their study of the authors’ English language teaching of immigrant and refugee women in Australia

Our Space: Being a Responsible Citizen of the Digital World

Our Space is a set of curricular materials designed to encourage high school students to reflect on the ethical dimensions of their participation in new media environments. Through role-playing activities and reflective exercises, students are asked to consider the ethical responsibilities of other people, and whether and how they behave ethically themselves online. These issues are raised in relation to five core themes that are highly relevant online: identity, privacy, authorship and ownership, credibility, and participation.Our Space was co-developed by The Good Play Project and Project New Media Literacies (established at MIT and now housed at University of Southern California's Annenberg School for Communications and Journalism). The Our Space collaboration grew out of a shared interest in fostering ethical thinking and conduct among young people when exercising new media skills

Web-based information on oral dysplasia and precancer of the mouth - Quality and readability

OBJECTIVES: The numbers of individuals with oral cancer are increasing. This cancer is preceded by oral epithelial dysplasia (OED). There remains no detailed study of the online information presently available for patients with OED or indeed what information such patients may require to be appropriately informed regarding their condition. Hence, the aim of the present study is to assess the patient-oriented web content with respect to OED. METHODS: The first 100 websites yielded from nine searches performed using different search terms and engines were considered. These were assessed for content, quality (DISCERN instrument, Journal of the American Medical Association benchmarks, and Health on Net seal) and readability (Flesch Reading Ease Score and Flesch-Kincaid Grade Level). RESULTS: There was a general scarcity of OED content across the identified websites. Information about authors, sources used to compile the publication, treatment, and shared decision were limited or absent. Only 6% and 27% of the websites achieved all the four JAMA benchmarks and HON seal, respectively. The average readability level was at 10th grade (US schools), which far exceeds the recommended levels of written health information. CONCLUSION: At present patients seeking information on OED are likely to have difficulty in finding reliable information from the Web about this disorder and its possible impact upon their life. Further work is thus required to develop a web-based resource regarding OED that addresses the shortfalls demonstrated by the current study

Computational Sociolinguistics: A Survey

Language is a social phenomenon and variation is inherent to its social nature. Recently, there has been a surge of interest within the computational linguistics (CL) community in the social dimension of language. In this article we present a survey of the emerging field of "Computational Sociolinguistics" that reflects this increased interest. We aim to provide a comprehensive overview of CL research on sociolinguistic themes, featuring topics such as the relation between language and social identity, language use in social interaction and multilingual communication. Moreover, we demonstrate the potential for synergy between the research communities involved, by showing how the large-scale data-driven methods that are widely used in CL can complement existing sociolinguistic studies, and how sociolinguistics can inform and challenge the methods and assumptions employed in CL studies. We hope to convey the possible benefits of a closer collaboration between the two communities and conclude with a discussion of open challenges.Comment: To appear in Computational Linguistics.

Introduction to Deadly Delusions #5

Barry Mauer began the comic series Deadly Delusions in 2013 in response to the increasingly extreme and dangerous right-wing propaganda he had observed over the past several decades. His aim for the project has been to combine scholarship, maximal rhetorical force, and a punk do-it-yourself aesthetic. Deadly Delusions shifts away from debates about whether the media is biased or if it is fair to both sides. Rather, it asks whether the media is spreading mass delusion and pushing eliminationist policies.peer-reviewe

(Mis)Attribution Symposium: Government Speech

In this Essay, I evaluate three issues of attribution and misattribution that arise in the so-called area of government speech. \u27 First, I explore when an individual might have a constitutional claim for misattribution by the state. Second, I discuss the citizen\u27s interest in proper attribution by the government when it is speaking. Third, I consider the government\u27s interest in avoiding expression being improperly attributed to it. This concern arises less often than is commonly assumed; what many scholars (and governments) claim to be a state interest in avoiding attribution or endorsement is in fact a state interest in not providing a platform for certain types of private speech. As such, the matter cannot be resolved according to the categories of public forum or government speech, and instead we must decide how much content-based decision- making is appropriate for the state when creating speech opportunities that fall into neither of these more doctrinally understandable forms
