Effects of Mass and Interpersonal Communication on Breast Cancer Screening: Advancing Agenda-Setting Theory in Health Contexts

Drawing on components of agenda-setting theory and the two-step flow of information from mass media to news audiences, this study examines the effects of mass and interpersonal communication on breast cancer screening practices among college- and middle-aged women (n = 284). We theorized that screening behaviors among younger women would be influenced more by interpersonal sources of information while screening among middle-aged women would be more influenced by exposure to mass-mediated information. Findings supported anticipated patterns, revealing important and varying roles for both mass and interpersonal communication in the health behaviors of women. Implications for health practitioners and campaign planners, as well as recommendations for future research, are discussed.     

Disciplined freedom,branded authenticity,and dependable independence: how tensions enact flexibility in lifestyle blogging careers

Analyzing 219 blog posts from 52 self-employed women lifestyle bloggers in North America, this study shows how these digital professionals navigate tensions and communicatively constitute work flexibility. In their narratives, women bloggers employed tension management approaches such as reframing, continual connections, and reflective practice in response to tensions in enacting temporal–spatial, identity, and financial flexibility. Specifically, women followed oxymoronic constructions – disciplined freedom, branded authenticity, and dependable independence – to embrace and transform competing poles of fluidity?structure, authenticity?marketability, and independence?interconnection. Expanding work–life research to the self-employed digital labor context, this study responds to recent calls to uncover more-than tension management strategies in empirical settings and contributes to a tension-centered, contextual, and processual analysis of workplace flexibility construction.     

It’s More Than Self-Presentation: MUM Effects Can Reflect Private Discomfort and Concern for the Recipient

Is the reluctance to share bad news (i.e., the MUM effect) motivated more by a public display or private concern, and does it benefit mainly the messenger or the recipient? An experiment (N = 309) that crossed good/bad news with three communication channels (face-to-face, text messaging, e-mail) revealed that messenger reluctance was greatest under conditions of bad news and did not vary based on the channel through which the recipient contacted the messenger. In contrast with earlier work, this MUM effect was more consistent with a private fear of distressing the recipient. Theoretical implications and limitations are discussed.

论抛锚式教学在高中政治课改中的张力

新一轮高中政治课改突出以学生为本，坚持学习中知识、能力和觉悟三者的有机结合。而将抛锚式教学运用于政治课，适应了课改的基本要求，能够凸显它的张力作用，使学生再现、建构、迁移知识；发展学生的社会实践能力、自主创新能力和判断选择能力；并在此过程中培养学生的团队精神、科学精神和感悟意识。     

论曹禺戏剧中的意象并置

曹禺戏剧中常常运用意象并置的诗化手段将看似散乱的材料进行“聚”与“收”的处理,以达到对材料深层寓意的充分挖掘。其意象并置的运用普遍而又多样;既有相似意象的对等,又有对比性意象的“跳跃衔接”,还有相同意象的多角度重复,它们与剧中浓郁的叙事性相互对抗,形成戏剧的内在结构张力。     

对大学学术自由和功利意识之间张力形成的认识

学术自由是大学尤其是研究型大学的“性格”，理所当然地要维护和弘扬。但是，随着经济的发展，尤其在知识经济年代，社会越来越要求大学体现服务功能。于是，在市场化和效益化的社会背景下，大学在发展过程中不可避免地产生了功利意识，从而形成了学术自由和功利意识之间的矛盾和张力。

用拉压不同模量理论计算支座移动引起的超静定结构内力

For statically indeterminate structure, the internal force will be changed with the translation of the supports, because the internal force is related to the absolute value of the stiffness EI. When the tension is different with the compression modulus, EI is the function of internal force and is not constant any more that is different from classic mechanics. In the other words, it is a nonlinear problem to calculate the internal force. The expression for neutral axis of the statically indeterminate structure was derived in the paper. The iterative program for nonlinear internal force was compiled. One case study was presented to illustrate the difference between the results using the different modulus theory and the single modulus theory as in classical mechanics. Finally, some reasonable suggestions were made for the different modulus structures.
