Oh and LaRose (2016) contended that problem severity and channel publicness shape support seekers’ goals, time spent composing messages, and the sophistication of those messages. The current study seeks to replicate and extend Oh and LaRose’s study to produce a more accurate understanding of the factors that influence the sophistication of support-seeking messages online. Support seekers’ goals varied according to the severity of a stressor and the publicness of a channel, and the amount of time people spent composing a message influenced its sophistication. We extend the original study by examining associations that were not initially tested. Time spent composing messages mediated the influence of problem severity on the quality of people’s messages, and this effect was moderated by channel publicness. 相似文献

This study examined whether perceived message effectiveness (PE) predicted information-seeking behavior in the topical domain of colon cancer. Participants (N = 277) viewed one of three video messages (news, testimonial, and animation) that advocated screening for colon cancer. Information-seeking behavior was operationalized as reading time for a subsequent message about colon cancer. The proposed mediation model successfully reproduced the pattern of data, thereby providing evidence that PE predicts behavior via intention. 相似文献

Objective
The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.Methods
Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.Results
All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.Conclusions
None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers. 相似文献5.

The study reported here examined the influence of anonymous sources on health websites on the perceptions and attitudes of information seekers. It was hypothesized that, despite the warnings and guidelines established by health organizations, anonymous sources would be perceived to be as credible and influential as sources that were identified. The anonymity effect, drawn from the similarity principle in attribution theory, was forwarded as a theoretical mechanism to explain responses to anonymous sources. The results indicated that anonymous sources were generally perceived by participants to be as credible and influential as identified sources, although the anonymity effect explanation was not supported. The implications of these findings for information seekers and health practitioners are considered. 相似文献

Self-assessment practices can positively impact student learning and achievement. However, less is known about psychological moderators that can influence the impact that self-assessment practice may have on achievement. Integrating the dual processing self-regulation model and the self-assessment cycle framework, this study examined the role of students’ positive well-being in the link between self-assessment practices and domain-specific achievement scores. Hierarchical multiple regression analyses using data from 765 secondary school students revealed that self-assessment practices positively predicted achievement scores. Results also showed that positive well-being moderated the relationship between seeking internal feedback and self-reflection and achievement scores, in that the positive link between such self-assessment practices and achievement was stronger for students who had low or moderate well-being. These findings reinforce the impact of self-assessment on learning and add to the ecological validity of the dual processing self-regulation model. The discussion focuses on how these findings contribute to our understanding of how well-being could influence the adaptive role of internal and cognitive self-assessment practices in student learning. Limitations and future research directions are also discussed. 相似文献

陶渊明“好名”的原因包括：内在精神的需要、历史文化的熏染、家族功勋的陶冶、社会风气的影响、先贤道义的作用以及道家思想的缺陷等几个方面。这些原因进一步说明了他的“好名”的客观必然性,有力地证实了他的人格的复杂性。 相似文献
