Information Literacy Self-Efficacy Scale: Validating the translated version of the scale for use among Bangla-speaking population

The main aim of this paper is to evaluate the validity of a translated version the Information Literacy Self-Efficacy (ILSE) scale in a different socio-cultural context in Bangladesh. The 28-items of the ILSE scale was translated into Bangla to collect data from students of a public university in Bangladesh. To determine the underlying factor structures of the 28-items scale and its short version of 17-items, exploratory factor analyses (EFAs) were conducted with a sample of 394 students. Confirmatory factor analyses (CFAs) were performed with a group of undergraduate students (n = 267) to examine the validity of the scale. The 28-items and 17-items versions of the scale extracted four factors and three factors, respectively. In the CFA analyses, 23 out of the 28-items were found reliable although discriminant validity was not achieved between two constructs. While analyzing the 17-items subscale, 13-items were found to be reliable. Overall, the CFA model fit statistics for both the 23-items and 13-items support the use of the translated version of the ILSE scale for assessing self-efficacy for information literacy among Bangla-speaking population.     

Self-Efficacy and the First-Year University Student's Authority of Knowledge: An Exploratory Study

Interviews with a small group of first-year university students assessed perceived self-efficacy in the domain of the ability to locate information in two different research contexts. The study paid particular attention to differences between female and male participant responses. Directions emerged for further research into the relationship between students' perceived self-efficacy with regard both to locating information and to constructing new knowledge.

Internet Economics: An Annotated Bibliography

This is an annotated bibliography of recent works (papers, articles, and book chapters) in the burgeoning field of Internet economics. Publications on Internet economics were sought through traditional research means and by searching the World Wide Web. An introduction to the bibliography explains how the references were sought and identifies key themes that emerge from the research, particularly as they relate to media scholarship. Entries are listed in alphabetical order. Each citation is accompanied by an annotation of at least a few sentences that summarize the cited work's key points as they relate to Internet economics.     

移动互联环境下用户跨屏行为整合分析框架——基于扎根理论的探索

用户跨屏行为是移动互联环境下用户信息行为嬗变的时代性标志,引发了多学科、交叉领域的关注。目前关于用户跨屏行为的研究较为分散,缺乏对跨屏行为机理的系统聚焦与整合性探讨。作为探索性研究,本文尝试通过质性的扎根理论方法,结合深度访谈与焦点小组资料,借鉴Strauss的三阶段分析法,构建“双层—四维”的UTIT整合分析框架,具体涵盖了9个主范畴,39个范畴和117个初始概念。研究从用户、任务、信息、技术四个维度,综合考察用户跨屏行为的外部表现与内部动因,提炼出表现、因果、中介、调节四类关系。该框架在理论上弥补了传统研究中将行为动因与表现形式二元割裂的局限性,并延伸出用户跨屏行为的四大类研究命题与研究方向。图2。表5。参考文献27。     

结构性缺失:网络时代把关理论的重新考察

把关理论的基本结构由把关人、门卡、把关对象、把关机制、把关关系等要素组成。传统把关理论的主要贡献在于对把关人、把关过程和把关分析层次的重视,忽视了对把关对象、把关关系、把关机制等要素的研究,导致了结构性的缺失。在网络时代,把关理论研究需要进行结构性调适,如从沉默到挑战的把关对象,从支配到对抗/协作的把关关系,从单一到多元的把关机制。基于以上要素的层次分析,提出了动态化、透明度、复杂性是网络时代把关理论结构性研究的三大趋势。     

Influence of Social Identity on Self-Efficacy Beliefs Through Perceived Social Support: A Social Identity Theory Perspective

While much research documents the influence of self-efficacy on enactment of health behaviors, relatively less attention has been given to the factors that influence self-efficacy. To enhance our understanding of the various sources of self-efficacy, this study integrated social identity theory into this context and proposed and tested a model, which describes a process through which social identity can influence self-efficacy of engaging in health-related behaviors. Consistent with the proposed meditational model, the findings showed that individuals who had stronger social identity with a given social group perceived greater social support from the group, which in turn predicted higher self-efficacy of engaging in a health-related behavior advocated by the group, and ultimately predicted greater behavioral intention. Theoretical and practical implications are discussed.

网络时代的写作--探讨与展望

互联网正在改变我们的世界。它不仅仅是一种单纯的提供信息的手段,而是越来越多地改变我们的生活方式甚至在形成一种全新的生活方式。 自从1990年代初以来,一些传播学家就一直在预言,在下一个十年中,所谓的信息高速公路网络将通过某种正如未来学家乔治·吉尔德所称的电信电脑一种将电脑、电信和个人电脑的特性混合起来的     

Information Sources and the Health Information-Seeking Process: An Application and Extension of Channel Complementarity Theory

Contemporary information seekers can acquire health information from an unprecedented variety of sources. The reported study applied and extended channel complementarity theory to explain the use of multiple information sources in the health-information-seeking process. Channel complementarity was extended to consider four characteristics (i.e., access to medical expertise, tailorability, anonymity, and convenience) of health-information sources. The information-seeking behavior of 3,392 respondents from the 2007–2008 Health Information National Trends Survey was analyzed to test study hypotheses. Results indicate that, sources were used complementarily based on tailorability and anonymity during health-information sources. Additionally, the likelihood of using complementary sources based on all four characteristics changed during the search process.

Media Self-Efficacy: Validation of a New Concept

In this study, we provide evidence of construct and discriminant validity for measures of self-efficacy in using television, newspaper, and interpersonal communication to monitor politics in everyday life. Data were drawn from a survey of undergraduates (N = 576) at a large public university. Self-efficacy is a key mediating variable in social learning theory, consisting of a combination of beliefs that one can perform tasks and that desired consequences follow from successful performance. Self-efficacy subscales were correlated with media uses, exposure, intellectual stimulation, credibility, political efficacy, and participation, which supported construct validity of measures. Subscale correlations supported the discriminant validity of media self-efficacy measures.
