A Broad Evaluation of the Tor English Content Ecosystem

Tor is among most well-known dark net in the world. It has noble uses, including as a platform for free speech and information dissemination under the guise of true anonymity, but may be culturally better known as a conduit for criminal activity and as a platform to market illicit goods and data. Past studies on the content of Tor support this notion, but were carried out by targeting popular domains likely to contain illicit content. A survey of past studies may thus not yield a complete evaluation of the content and use of Tor. This work addresses this gap by presenting a broad evaluation of the content of the English Tor ecosystem. We perform a comprehensive crawl of the Tor dark web and, through topic and network analysis, characterize the types of information and services hosted across a broad swath of Tor domains and their hyperlink relational structure. We recover nine domain types defined by the information or service they host and, among other findings, unveil how some types of domains intentionally silo themselves from the rest of Tor. We also present measurements that (regrettably) suggest how marketplaces of illegal drugs and services do emerge as the dominant type of Tor domain. Our study is the product of crawling over 1 million pages from 20,000 Tor seed addresses, yielding a collection of over 150,000 Tor pages. We make a dataset of the intend to make the domain structure publicly available as a dataset at https://github.com/wsu-wacs/TorEnglishContent.Comment: 11 page

Teaching about teaching and instruction on instruction: A challenge for health sciences library education

Objective: This is a review of the master's-level curricula of the fifty-eight America Library Association-accredited library and information science programs and iSchools for evidence of coursework and content related to library instruction. Special emphasis is placed on the schools and programs that also offer coursework in medical or health sciences librarianship. Methods: Fifty-eight school and program websites were reviewed. Course titles and course descriptions for seventy-three separate classes were analyzed. Twenty-three syllabi were examined. Results: All North American library education programs offer at least one course in the general area of library instruction; some programs offer multiple courses. No courses on instruction, however, are focused directly on the specialized area of health sciences librarianship. Conclusions: Master's degree students can take appropriate classes on library instruction, but the medical library profession needs to offer continuing education opportunities for practitioners who want to have specific instruction for the specialized world of the health sciences

Teaching English Language Learners to Vet Their Sources in the Post-Truth Paradigm

According to the Institute of International Education\u27s Open Doors report, the number of international students studying in the United States exceeded one million for the first time in 2016. Many of these students have insufficient command of the English language to pass the TOEFL or IELTS examinations required for enrollment at U.S. institutions of higher education, and as a result, programs designed to teach proficiency in the English language have been developed at some of these universities. In addition to English grammar and vocabulary, some programs also seek to acculturate students to Western academic norms such as critical thinking, academic integrity, and the paper-writing process to help students be prepared culturally as well as linguistically for American university life. Source evaluation has become an increasingly fraught topic for domestic and international students alike. Within the context of a lesson plan on this topic, this chapter will discuss the development of learning outcomes; an engaging anticipatory set which connects students’ background knowledge to the topic at hand; choosing readings appropriate for the topic and students’ comprehension level; the constructivist rationale for the main activity; and the logistics (timing, technology, etc.) of planning activities for ELLs versus domestic students

Wikipedia editing and information literacy: A case study

Purpose: This paper aims to evaluate the success of a Wikipedia editing assessment designed to improve the information literacy skills of a cohort of first-year undergraduate health sciences students. Design/methodology/approach: In this action research case study (known hereafter as “the project” to differentiate this action research from the students’ own research), students researched, wrote and published Wikipedia articles on Australia-centric health topics. Students were given a pre- and post-test to assess levels of self-confidence in finding, evaluating and referencing information. Student work was also analysed in terms of article length and quantity and the type of information sources used. Findings: Tests revealed that students’ self-confidence in their information literacy skills improved overall. Analysis of student work revealed that students wrote longer articles and incorporated more references than expected. References used were of appropriate quality relevant to the article despite minimal instructions. Originality/value: There are few studies that investigate information literacy development through Wikipedia editing in Australian universities. This study shows that Wikipedia editing is an effective way to carry out student assessment prior to essay writing and an innovative platform to improve information literacy skills in undergraduate students

Youth and Digital Media: From Credibility to Information Quality

Building upon a process-and context-oriented information quality framework, this paper seeks to map and explore what we know about the ways in which young users of age 18 and under search for information online, how they evaluate information, and how their related practices of content creation, levels of new literacies, general digital media usage, and social patterns affect these activities. A review of selected literature at the intersection of digital media, youth, and information quality -- primarily works from library and information science, sociology, education, and selected ethnographic studies -- reveals patterns in youth's information-seeking behavior, but also highlights the importance of contextual and demographic factors both for search and evaluation. Looking at the phenomenon from an information-learning and educational perspective, the literature shows that youth develop competencies for personal goals that sometimes do not transfer to school, and are sometimes not appropriate for school. Thus far, educational initiatives to educate youth about search, evaluation, or creation have depended greatly on the local circumstances for their success or failure

Teaching Health Impact and Behavior with Infographics

The use of Infographics can be a tool that not only allows for the communication of empirical health data in an understandable format, but encourages the health administration student to present evidence-based research in a creative manner. The purpose of this paper is to describe a learning exercise that implements Infographics to demonstrate an impact of a health issue and/or encourage a health behavior change. This learning exercise is developed to increase student knowledge and visual literacy skills with respect to presenting, in a concise format, a well-researched and referenced health issue and/or a health behavior change. Specifically, the exercise was designed to: (a) curate health statistics and reference information for the selected health issue; (b) identify media resources and apply copyright and fair use in a proper manner; (c) evaluate internet resources for credibility and accuracy; and (d) utilize Infographic tools to communicate one\u27s visual viewpoint. At the conclusion of the course, students reflected on the effective visual aspects of their Infographics and the points that were challenging to communicate using this medium. The benefits of this applied learning approach for students and the faculty instructor are discussed

Satirical News Detection and Analysis using Attention Mechanism and Linguistic Features

Satirical news is considered to be entertainment, but it is potentially deceptive and harmful. Despite the embedded genre in the article, not everyone can recognize the satirical cues and therefore believe the news as true news. We observe that satirical cues are often reflected in certain paragraphs rather than the whole document. Existing works only consider document-level features to detect the satire, which could be limited. We consider paragraph-level linguistic features to unveil the satire by incorporating neural network and attention mechanism. We investigate the difference between paragraph-level features and document-level features, and analyze them on a large satirical news dataset. The evaluation shows that the proposed model detects satirical news effectively and reveals what features are important at which level.Comment: EMNLP 2017, 11 page
