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.     

Testing Components of Confirmation: How Acceptance and Challenge from Mothers,Fathers, and Siblings are Related to Adolescent Self-Concept

The current study assessed how confirmation from family members (mothers, fathers, siblings) was related to adolescents' (ages 13–22) self-concepts. To extend confirmation theory, two components of confirmation were distinguished—acceptance and challenge—to understand their unique and combined contribution to predicting adolescent sense of self. 206 adolescents completed a general questionnaire, and a subset (n=60) completed daily diaries regarding conversations with family members. Analyses of the general perceptions of family interactions suggested the roles of acceptance and challenge in predicting adolescent sense of self varied by family member, whereas analyses of adolescents' reports of daily conversations suggested acceptance and challenge were strong predictors of sense of self regardless of family member. In addition, although the combination of acceptance and challenge was hypothesized to predict the strongest levels of sense of self, analyses suggested the effects of acceptance and challenge were additive. Adolescent participation in conversations, as hypothesized, also mediated the relationship between confirmation and sense of self. Overall, analyses provide partial support for the theoretical extensions, and directions for further theory development and future research are discussed.     

Naming and Claiming Cancer among African American Women: An Application of Problematic Integration Theory

This study examines how a sample of African American women understands the uncertainties fundamental to cancer risk communication. Utilizing data from four focus groups, Problematic Integration (PI) theory is applied as an interpretive lens for illustrating their felt difficulties of talking openly about cancer and breast cancer in everyday life. The women describe worry about cancer and its prevalence among African American women; ambivalence and uncertainty; belief that what is not uncertain is certain and awful; fear and avoidance; contradictions in “claiming” and “rebuking” cancer; and hopefulness.     

Analyzing Postcrisis Challenges and Strategies Associated With School Shootings: An Application of Discourse of Renewal Theory

In recent years, the need to understand and identify effective data-driven strategies for the communication challenges faced by schools associated with school shootings has become paramount. The current study reports findings from 10 face-to-face interviews conducted with school crisis team members at the P–12 level who experienced school shooting events. The findings, which extend discourse of renewal theory, identify six primary communication-related challenges that districts face postcrisis and offer effective strategies for overcoming these challenges.     

民国时期中美图书馆交流史序说:研究综述、理论基础与历史分期

民国时期的中美图书馆交流史不仅是理解中国图书馆与图书馆学缘起的重要议题,在回应图书馆领域史学研究的“双重困境”方面,也具有其特殊的价值。梳理民国时期中美图书馆交流史的相关文献和研究主题发现,本课题难点在于庞杂的线索、社群与诸多政治、经济因素的介入等。由此,本研究吸收“世界体系理论”“书籍交流圈”等跨学科的思想和方法,提出一个由宏观、中观和微观三个层次组成的理论视角,并阐述这一理论视角如何转化为具体的研究方法,以提高学界对民国时期中美图书馆交流史研究的整体理解和把控能力。研究发现,“专业交往”到“文化外交”的视角渐变是民国时期中美图书馆交流的核心轴线,以此可以将这段历史分为四个时期,帮助我们把握不同时期的交往脉络、主要成就和基本特点。表1。参考文献73。
