It Is Not Just a Matter of Ethics: A Survey of the Provision of Health Disclaimers,Caveats, and Other Health-related Alerts in Consumer Health Information on Eating Disorders on the Internet     

Feili Tu  Nancy P. Zimmerman 《International Information and Library Review》2013,45(3-4):325-339

Eating disorders affect millions of people, and their prevalence demonstrates that the condition exists across gender and cultural boundaries. The Internet is a major channel for publishing and disseminating electronic information, allowing worldwide access of massive health-related, lay- and professional-oriented information. However, much research has found that health-related information on the Internet can be overwhelming, incomplete, and/or inaccurate. The success of health promotion in the 21st century depends on whether available consumer health information (CHI) is adequate, accurate, and easy to use. Usually, health disclaimers, caveats, and other health-related alerts are messages to notify users that the information provided is not intended nor implied to be a replacement or an alternative for professional health-related advice. These messages also serve as indicators to show that information providers take ethical responsibility for quality control in terms of providing valid and reliable consumer health information on the Internet. The study used content analysis¹to examine the provision and assess the quality of health disclaimers, caveats, and other health-related alerts included in adult CHI on eating disorders published on the Internet in 1998. The researcher-generated instrument was based on evaluative criteria derived from Alexander and Tate;²Health On the Net Foundation;³Mitretek Systems;⁴and Silberg, Lundberg and Musacchio.⁵Web search engines (Northern Light, HotBot, and Excite) were used for data collection on Internet-based publications. The results indicated that the CHI on eating disorders on the Internet did not include disclaimers, caveats, and other health-related alerts which demonstrates a lack of quality control and ethical responsibility on the part of the information providers and site administrators.  相似文献   

Expanded Assessment Study Examining the Citation Patterns from Traditional and Nontraditional Institutions and Their Effect upon the Quality of Doctoral Dissertation Reference Lists     

Johanna Tuñón  Bruce Brydges 《图书馆管理杂志》2013,53(1-2):137-159

ABSTRACT

This study used citation analysis in conjunction with a subjective rubric with five validated criteria to assess the quality of a purposive sample of 452 education dissertation reference lists produced at a nontraditional institution from six doctoral programs. These programs used a variety of distance education models. The citations were then compared with the 100 reference lists selected from doctoral education programs at 10 traditional institutions. Criteria included the breadth of resources, depth of the literature review as shown through the citing of critical historical and theoretical works, depth as demonstrated through the scholarliness of citations chosen, currency, and relevancy. The study discusses how the expanded sample of traditional reference lists continued to demonstrate consistent patterns. In contrast, although the sample of reference lists from distance education programs was much expanded, the patterns of the subsets of reference lists at the nontraditional institution were significantly diverse. The patterns of 35 doctoral reference lists from another for-profit, nontraditional institution known for providing distance education were also examined to compare the results of the two nontraditional programs. Possible reasons for differences in citation patterns by traditional and nontraditional programs are discussed, and the possible role of distance education and program criteria are examined for insights they offer into the use of citation analysis as an assessment tool of the library research skills of doctoral students.  相似文献   

How Chinese Perceive Social Presence: An Examination of Interaction in Online Learning Environment     

Chih-Hsiung Tu 《Educational Media International》2013,50(1):45-60

Chinese students utilize more social context cues to communicate with others. They are accustomed to processing information from either a physical context or an internalized appreciation of the person. Current literature documents that computermediated communication (CMC) is unable to deliver social context cues. Because of the burgeoning importance of computers in education it becomes important to determine how Chinese students perceive CMC. An ethnographic approach with a dramaturgy strategy was used in this study to examine the Chinese student's interactions and perceptions of social presence in online learning environments. The results indicated that three dimensions of social presence, social context, online communication and interactivity affected Chinese students' perceptions of CMC. The feeling of private/public was identified as an important factor related to the level of social presence. When integrating CMC into an online learning environment, it is necessary to consider the student's local culture, language skills, keyboarding skills, format of CMC, face saving, computer literacy, use of paralanguage and emoticons, responsiveness of asynchronous communication, use of stylistic communication styles, and feelings of private/public.

Comment les Chinois percoivent la présence sociale : un examen de l'interaction sur la formation en ligne à l'environnement.

Les étudiants Chinois utilisent plus de signes de contacte social pour communiquer avec les autres. Ils ont l'habitude de manière l'information sert dans un contexte physique ou à partir d'une interprétation intériorisée de la personne . Les documents fournis par la littérature qui est une communication médiatisée par l'ordinateur (CMC) sont incapables de fournir ces signes de contextes sociaux. Comme l'information des ordinateurs en éducation augmente, il devient important de déterminer comment les étudiants Chinois percoivent le CMC. Une approche ethnographique avec une stratégie de dramaturgie a été utilisée pour examiner les interactions et les perspectives de présence sociale, de contexte social dans les environnements d'apprentissage en ligne. Les résultats ont montré que les trois dimensions de présence sociale, de contexte social, de communication en ligne et d'interactivité ont affecté les perceptions de CMC pour les Chinois. Le sentiment privé/public a été identifié comme un facteur important pour le niveau de présence sociale. Quand on intègre le CMC dans un apprentissage en ligne, il es nécessaire de considérer la culture locale de l'étudiant, ses qualifications en langues, sa habilité avec le clavier, le format du CMC, la facon de sauver la face, son lettrisme en ordinateur, l'utilisation de paralangages d'émotions, ses réponses à une communication asynchrone, l'utilisation de style de communication stylique et les sentiments privés/publics.

Wie Chinesen soziale Präsenz empfinden: Eine Untersuchung über Interaktion in einer Online Lernumgebung.

Chinesische Studenten nutzen mehr Stichworte aus dem sozialen Kontext um mit anderen zu kommunizieren als andere. Sie sind gewohnt, Informationen entweder aus einem physischen Kontext oder aus einer verinnerlichten Wertschätzung der Person heraus zu verarbeiten. Die gegenwärtige Literatur belegt, dass Computer-vermittelte-Kommunikation (CMC) nicht in der Lage ist, Reize mit sozialem Kontext zu liefern. Wegen der wachsenden Wichtigkeit von Computern in der Erziehung wird es wichtig, herauszufinden, wie chinesische Studenten CMC empfinden. Wir benutzten einen ethnographischen Einstieg mit einer dramaturgischen Strategie, um die Interaktion und Empfindungen von sozialer Präsenz in online-Lernumgebungen zu untersuchen. Die Ergebnisse zeigen, dass drei Dimensionen sozialer Präsenz (Sozialer Bezug, Online-Kommunikation und Interaktivität) die Empfindung von CMC bei den chinesischen Studenten hervorriefen. Das Gefühl von Privatheit/Öffentlichkeit wurde als wichtiger Faktor bezüglich der Stärke der sozialen Präsenz festgestellt. Wenn man CMC in eine Online-Lernumgebung integriert, ist es notwendig, die örtliche Kultur, Sprachkenntnisse, Schreibfertigkeit, das Format von CMC, Verletzlichkeit, Computerkenntnisse, Gebrauch von Para-Sprache und Emoticons, Ansprechbarkeit auf asynchrone Kommunikation, den Gebrauch von stilistischen Kommunikationsweisen und Gefühle von privat/öffentlich zu betrachten.  相似文献
