This article presents an innovative methodology to study computer-mediated communication (CMC), which allows analysis of the multi-layered effects of online expression and reception. The methodology is demonstrated by combining the following three data sets collected from a widely tested eHealth system, the Comprehensive Health Enhancement Support System (CHESS): (1) a flexible and precise computer-aided content analysis; (2) a record of individual message posting and reading; and (3) longitudinal survey data. Further, this article discusses how the resulting data can be applied to online social network analysis and demonstrates how to construct two distinct types of online social networks—open and targeted communication networks—for different types of content embedded in social networks.  相似文献   

Product review summarization through question retrieval and diversification     

Mengwen?Liu  Yi?FangEmail author  Alexander?G.?Choulos  Dae?Hoon?Park  Xiaohua?Hu 《Information Retrieval》2017,20(6):575-605

Product reviews have become an important resource for customers before they make purchase decisions. However, the abundance of reviews makes it difficult for customers to digest them and make informed choices. In our study, we aim to help customers who want to quickly capture the main idea of a lengthy product review before they read the details. In contrast with existing work on review analysis and document summarization, we aim to retrieve a set of real-world user questions to summarize a review. In this way, users would know what questions a given review can address and they may further read the review only if they have similar questions about the product. Specifically, we design a two-stage approach which consists of question selection and question diversification. For question selection phase, we first employ probabilistic retrieval models to locate candidate questions that are relevant to a given review. A Recurrent Neural Network Encoder–Decoder is utilized to measure the “answerability” of questions to a review. We then design a set function to re-rank the questions with the goal of rewarding diversity in the final question set. The set function satisfies submodularity and monotonicity, which results in an efficient greedy algorithm of submodular optimization. Evaluation on product reviews from two categories shows that the proposed approach is effective for discovering meaningful questions that are representative of individual reviews.  相似文献   

Toward collaborator selection and determination of data ownership and publication authorship in research collaborations     

Besiki Stvilia  Charles C. Hinnant  Shuheng Wu  Adam Worrall  Dong Joon Lee  Kathleen Burnett  Gary Burnett  Michelle M. Kazmer  Paul F. Marty 《Library & information science research》2017,39(2):85-97

This study examined factors that might affect researchers' willingness to collaborate with a specific researcher and the priorities given to those factors. In addition, it investigated how researchers determined the ownership of collaborative project data and how they determined the order of authorship on collaborative publications in condensed matter physics. In general, researchers rated their intrinsic motivations the highest, such as the quality of ideas a potential collaborator might have and their satisfaction with a past collaboration, followed by their extrinsic motivations, such as the complementary knowledge, skills, or resources the collaborator could provide. In addition, researchers who had a greater number of collaborative projects and researchers who had served as a project PI or co-PI valued the deep-level, personality-related characteristics of a collaborator higher than did those who had not. Younger researchers were more risk averse and more concerned with a collaborator's reputation and the possible cost of a collaboration decision. Additionally, younger researchers indicated more often than older researchers that they did not know whether their project teams followed any rules or norms or engaged in negotiation to determine the order of authorship on collaborative publications.  相似文献

Autonomy of Artistic Expression for Adult Learners with Disabilities     

Graham C. Young 《The International Journal of Art & Design Education》2008,27(2):116-123

When an art tutor adopts the role of assistant to a disabled artist it is difficult not to move from helping with the physical handling of materials on the one hand into the actual creative process on the other, thus influencing how the artwork looks. Ecas is an Edinburgh‐based charity which promotes opportunities for physically disabled people to be self‐fulfilled and to participate in all aspects of society. They run, among other things, traditional art classes and computer classes. The use of computer technology (CT) in art seemed to offer the chance for self‐fulfilment for disabled artists by increasing control over artistic choices and providing for self expression with only minimal assistance required from others. Ecas decided to fund a research project in the form of a ten‐week pilot course and the data collected during the trial confirmed these possibilities and it was clear that adult learners with disabilities could benefit from CT in order to have greater autonomy in the creation of their art than before. In particular the program Corel Painter IX.5 and various graphics tablets proved to be a powerful arsenal for self‐expression without having to wait for a tutor to tape paper to a board, replenish paint, change brushes attached to a head pointer or any one of the many and varied problems disabled students had with traditional art materials.  相似文献

Finding Common Ground: A Synthesis of Science and Mathematics Teacher Educators’ Experiences with Professional Growth     

Park Rogers  Meredith  Berry  Amanda  Krainer  Konrad  Even  Ruhama 《International Journal of Science and Mathematics Education》2021,19(1):167-180

The seven articles that comprise this Special Issue examine the professional growth of mathematics and science teacher educators across different contexts and different foci of who is the teacher educator being studied. Despite these differences, a common thread running throughout these seven articles is the need for learning to be situated in collaboration with others. In this final article, we examine the contribution of these articles through two perspectives: that of the collaborative contexts supporting the professional growth of mathematics and science teacher educators, and the role of disciplinary knowledge as part of the purpose for teacher educators’ professional growth. We notice that collaboration can take on very different structures in supporting teacher educators’ professional learning due to the different purposes and roles of the teacher educators in the studies. We also notice that while collaboration figures as an important component in all of the studies, the disciplinary specific aspects of collaboration, i.e., how collaboration might be negotiated differently by teacher educators in mathematics and science, is still not well understood. Overall, these articles provide important insights that help to shed new light on the complex and multifaceted nature of teacher educators’ learning and growth and provide productive avenues for future research.

The Hidden Curriculum of Domestication     

Juan S. Muñoz  Rosario Ordoñez Jasis  Patricia A. Young  Peter McLaren 《The Urban Review》2004,36(3):169-187

Four ethnically diverse faculty members in the field of education discuss the professional impact and personal affects of introducing critical themes of race, class, gender, and culture within their research and course offerings. Given that the professional outlook for university faculty of color in general, is grim, a willingness to imbue their research and courses with a critical interrogation of prevailing education topics and theories would seem to invite greater personal risk and professional jeopardy. The following dialogue introduces both the mechanisms by which critical faculty in general, and faculty of color in particular, can be conditioned to subordinate their critical impulses and the strategies they use to resist academic cultures of domestication.  相似文献   

Gender differences in science achievement: Do school effects make a difference?     

Deidra J. Young  Barry J. Fraser 《科学教学研究杂志》1994,31(8):857-871

The problem of the underrepresentation of girls in science in Australian schools is often attributed to their poor performance. Yet the role of both the home and the school in affecting female science achievement is rarely examined empirically. The comprehensiveness of the Second International Science Study database provided an excellent opportunity to investigate the presence of gender differences in science achievement. Although previous studies of gender differences in science achievement have relied on methodology that has not adequately accounted for the school effects, this study used the design effect and hierarchical linear modeling (multilevel analysis) to explore whether there were significant gender differences. The relative contribution of schools to student achievement was examined, and school-level differences were found to contribute significantly toward explaining variations in student performance. Although statistically significant sex differences were found in physics achievement for 10-year-old, 14-year-old, and year-12 students, school effects were much more powerful in explaining student differences (9–19%) when compared with gender (3%).  相似文献
