Development and Validation of the Student Interest and Engagement Scales

A series of studies report the development of empirically derived instruments that measure student interest and engagement. The first study inductively develops an initial item pool through open-ended questionnaire data. A second study subjects the measures to exploratory factor analysis to ascertain an underlying factor structure. The third study deductively tests the measures through confirmatory factor analysis and examines associations among teacher communication behaviors, student emotional and cognitive interest, and engagement. A fourth study offers discriminant validity evidence, suggesting that the new measures are distinct from scales that assess similar yet divergent constructs. Guided by prior theory (Mottet, Frymier, & Beebe, 2006 Mottet, T. P., Frymier, A. B. and Beebe, S. A. 2006. “Theorizing about instructional communication”. In Handbook of instructional communication, Edited by: Mottet, T. P., Richmond, V. P. and McCroskey, J. C. 255–282. Boston, MA: Pearson.  [Google Scholar]) and research (Harp & Mayer, 1997 Harp, S. F. and Mayer, R. E. 1997. The role of interest in learning from scientific text and illustration: On the distinction between emotional interest and cognitive interest. Journal of Educational Psychology, 89: 92–102. [Crossref], [Web of Science ®] , [Google Scholar]), the instruments developed here possess heuristic potential for instructional communication research. Implications and areas for future research are discussed.     

Measuring Online Communication Attitude: Instrument Development and Validation

This paper reports a series of studies that develop an empirically-derived instrument for assessing online communication attitude, a multidimensional set of individual cognitive-affective constructs that influence media choice. The first study inductively develops an initial item pool and tests dimensional structure via exploratory factor analysis. The second study further refines this structure and also tests the association between online communication attitude and media use in same-sex friendships. Finally, the third study deductively tests global model fit via confirmatory factor analysis, and establishes concurrent validity with theoretically related communication constructs. Beyond identifying motives underlying media choice, the instrument developed here possesses heuristic potential for clarifying media choice theory and elaborating the association between communication competence and media choice.     

影视时代读者的瓦解与建构

1990年代以来,大众传媒和商业意识的崛起,彻底瓦解了传统的读者群,阅读成为一个分化的小部落行为,阅读趣味也发生了巨大的分裂。强大的大众传媒力量构建了一个权利的话语体系,读者的阅读行为也被纳入到这一强大的媒介话语的生产结构之中。在以电视传媒为代表的大众文化日益渗透的影响下,受众的阅读心理呈现出一种娱乐化的特征,读者的阶层呈现全面的分化。在电视的强大影响下,阅读开始以家庭或小群体为单位,随着电视的指针而选择同一种阅读类型。当影视文化建构起的消费主义意识形态深刻地引导着受众的消费——购买影视图书的时候,读者就成为马尔库塞所说的“单向度的人”．

Approaches,Techniques, and Criteria for Serials Evaluation in the Electronic Environment

Abstract

An overview of traditional methods of evaluating serials collections and serial titles is presented and applied to electronic resources. Traditional methods such as holdings, checklist, conspectus, availability studies, document delivery studies, citation studies and use studies used for the evaluation of serials collections in print can be modified for the evaluation of electronic serials collections. Issues, problems and challenges associated with electronic serials evaluation are then outlined, and conclusions that emphasize the continuing importance of serials evaluation in the electronic environment are drawn.     

Movie Stars and the Volatility of Movie Revenues

Research has found conflicting results regarding the profitability of movies that have big-name stars. Why then, are stars selected to act in movies? Using the concepts of risk, volatility, and brand loyalty, this research proposes that although stars may not guarantee profits, their presence results in lower weekly revenue volatility. Using a database comprising 41 stars and their presence in 467 movies from over a 26-year period, this study finds broad support for this hypothesis.     

知识融合:概念辨析与界说

[目的/意义] 知识融合是一个随技术环境和社会环境不断发展变化的概念,并可应用于多个学科领域,然而目前学术领域对知识融合的概念界定还缺少一致的理解,对其进行辨析有利于推动后续研究。[方法/过程] 通过充分调研和分析,在理论和实践层面汲取以往研究中的观点和成果,一方面选取不同时期和不同领域的知识融合概念的典型表述,并分别提取“处理对象”“融合过程”以及“融合结果”3个关键要素;另一方面通过知识融合系统体系架构的剖析来进一步明确知识融合的研究范畴与边界。[结果/结论] 综合概括得到一个相对完整的知识融合概念定义,并从流程角度对知识融合概念进行分解。

Evaluation of digital libraries: Criteria and problems from users' perspectives

Digital library research has developed over the past decade, but little has been done on the identification of evaluation criteria, especially from users' perspectives. This article identifies users' criteria and applies them to the evaluation of existing digital libraries. Forty-eight subjects were instructed to develop and justify a set of essential criteria for the evaluation of digital libraries. At the same time, they were requested to evaluate existing digital libraries by applying the criteria that they were developing. A compilation of criteria developed by participants show that usability and collection quality were the most important criteria for evaluating digital libraries. Service quality, system performance efficiency, and user opinion solicitation were also deemed essential criteria. The author further compares digital library evaluation criteria identified by users and researchers and applied in previous research. The article reveals problems in current digital library design and development, discusses suggestions for improving digital library design, and presents areas for further research.     

所见、所感与所知：用户的注意力、主观感受和在线健康信息质量评价关系探究

健康网站是用户获取健康信息的重要来源,在线健康信息的质量关系到患者、医生、网站运营商等所有相关者的利益。网站页面元素是在线健康信息的载体,用户对信息质量的评价依赖于对页面元素的感知。本研究基于在线健康信息质量评价原则划分页面元素,采集和分析相关页面元素上的注意力分配;利用调查问卷收集质量评价数据,分析质量评价与页面元素注意力分配的相关性;通过凝视提示回顾式发声思考和半结构化访谈获取用户的主观感受,以解释质量评价与页面元素注意力分配之间的关系。研究结果发现,相比于其他页面元素,用户在医生认证资质和广告上的注意力分配较多;用户对健康信息权威性、保密性、公开性和广告政策的评价分别与相应页面元素的注视次数和注视时间正相关,对补充性和归因性的评价分别与相应页面元素的注视次数和注视时间负相关,而对合理性和透明性的评价与相应页面元素的注视次数和注视时间不相关;最后,从用户主观感受的角度揭示了注意力分配和质量评价产生关系的内在原因。本研究丰富了在线健康信息质量评价理论基础和研究方法,研究结论为改善在线健康信息内容质量和健康网站界面设计提供了参考。

Message fatigue: Conceptual definition,operationalization, and correlates

Despite growing concern over the public’s fatigue toward inundated health messages, communication research has largely neglected such ramifications of prolonged, real-life campaign exposure. This paper offers an initial conceptual and empirical treatment of message fatigue, an important, but understudied, side effect of campaigns. Specifically, it proposes conceptual and operational definitions of the construct and examines psychometric characteristics of a proposed message fatigue scale. The findings from two studies concerning safe sex (N?=?412) and anti-obesity messages (N?=?396) demonstrated solid support for the scale’s unidimensionality. In support of construct validity, the scale exhibited significant associations with message avoidance, annoyance, information seeking, and desensitization. Moreover, in an experimental setting in Study 2, message fatigue negatively predicted attention and message elaboration, while positively predicting counterargument.     

Measuring Exposure to Direct-to-Consumer Advertising: A Validation Study in the Context of Cancer-Related Treatment Advertising

This research examines two recurrent conceptual issues of measuring media exposure in survey research—content specificity of survey items and whether exemplars should be provided to aid recall. In two population-based surveys, we evaluated three candidate measures of cancer patients’ self-reported exposure to cancer-related direct-to-consumer advertising (CR-DTCA); these measures varied in content specificity and provision of ad exemplars. All three measures performed equally well in terms of internal consistency, convergent, nomological, and discriminant validity. Increased content specificity or ad exemplars did not improve performance of the exposure measures. Participants were able to extrapolate from ad exemplars to report their exposure to broad categories of CR-DTCA. The briefest of the three measures posed the lowest level of survey costs and was deployed successfully for mailed and internet-based survey administration. We discussed future directions for application of these findings in DTCA research for other illness and for media exposure research more generally.
