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.  相似文献

This paper reports research results of the proposed experiential learning using a game-based educational material. The educational material was an application running on a mobile device and was supported for learners to study university library instruction. During the experiential learning, the learners answered several quizzes provided from the educational material. The quizzes were including experiential contents such as actually to find an academic journal or to reserve a learning room. In order to evaluate learning effectiveness of the experiential learning, this research made a comparative experiment. The experimental group used the educational material and the control group used another educational material of e-learning (non-experiential) but the contents was almost same as the contents of the experiential learning. The comparative experiment took several evaluation elements such as pre-/post-test scores, delayed-test scores and learning motivation scores based on IMMS of ARCS model. The experimental results revealed that experiential learning was superior for the several elements of these metrics. This research, furthermore, analyzed learner's operation data to the educational material and learner's behavior data during the learning in the experimental group. The analyzing results showed three types of the learning behaviors and indicated that an instructor needs to adopt suitable instructional design to each type to bring superior learning effectiveness.  相似文献

Neurasthenia (shenjing shuairuo) and depressive disorder are medical issues that have given rise to disputes in China for more than 20 years. Since the 1980s, the once ubiquitous diagnosis of neurasthenia in China was rapidly substituted by depressive disorder in the clinical context. Globally, the metamorphosis from neurasthenia to depressive disorder heralded the triumph of scientific rationality, which identifies neurasthenia as a categorical fallacy. In China, however, neurasthenia retained social and cultural significance; thus, it has become a contestable discourse in relation to depressive disorder. By examining the health reporting of both discourses over a decade, this study explicated how neurasthenia and depressive disorder were represented in a popular health newspaper in China. The content analysis showed that neurasthenia is a more culturally and everyday embedded discourse closely associated with Chinese medicine and laymen’s discourse, while depressive disorder is more associated with Western medicine and the professional discourse. The differentiation of two sets of medical discourse evinces that despite the ostensibly prevailing scientific rationality in media health reporting, cultural rationality is deeply embedded in communicating mental health issues with the lay public. It further suggests the significance of investigating the social and cultural expression of mental illnesses in China.  相似文献

The National Institutes of Health (NIH) library instruction program provides training services to staff, clinicians, and researchers across NIH and several Department of Health and Human Services (HHS) operating divisions. The audience, training needs, and training topics are diverse and constantly changing. The NIH library has developed several new services and class topics to meet the needs of its NIH and HHS communities. Context, strategies, and future directions for the NIH library instruction program are described.  相似文献

The objectives of the study were to assess the prevalence of child sexual abuse (CSA) in a nation-wide representative sample of 14–17 year old Israeli adolescents, and to examine the associations between CSA, socio-demographic correlates and various measures of physical and mental health. The study population consisted of 906 mother–adolescent dyads, belonging to a community based, representative sample of Israeli 14–17 year olds, interviewed in 2004–5. Response rate was 68%. Subjects provided demographic data, and information about CSA, physical symptoms, body image, well-being and use of mental health services. DAWBA was used to obtain information regarding mental disorders and suicidality. SDQ was used to obtain data on bullying. Statistical analyses were conducted using an SPSS-17 complex sample analysis module and multivariate analyses were conducted to assess the associations between CSA and risk factors and social and health related correlates. Findings show that CSA was reported by 3.3% of adolescents. Higher risk of exposure to CSA was found among girls, among adolescents living in a one-parent household and among adolescents with a chronic disability. In multivariate models adjusting for gender, learning disabilities and depression, CSA was associated with suicidal attempts, stomach ache, dizziness, sleep problems, well being at home and bullying behaviors. No association was found with suicidal ideation or other physical symptoms. Our findings confirm that the associations between CSA and different outcomes vary depending on the socio-psychological context, and underline the importance of addressing the complexity of variables associated with CSA.  相似文献

This paper examines the long-run relationship between school bullying exposure and later adult health using a nationally representative household survey data from China. Our results show that victims are more likely to have low self-reported health, chronic diseases, physical functional limitations, and mental health problems even after several decades. The negative health consequences are more concentrated on the disadvantaged who come from low-income households or lack family support. The main findings are also consistent with qualitative evidence of our online survey.  相似文献

The use of the internet and social media have changed consumer behavior and the ways in which companies conduct their business. Social and digital marketing offers significant opportunities to organizations through lower costs, improved brand awareness and increased sales. However, significant challenges exist from negative electronic word-of-mouth as well as intrusive and irritating online brand presence. This article brings together the collective insight from several leading experts on issues relating to digital and social media marketing. The experts’ perspectives offer a detailed narrative on key aspects of this important topic as well as perspectives on more specific issues including artificial intelligence, augmented reality marketing, digital content management, mobile marketing and advertising, B2B marketing, electronic word of mouth and ethical issues therein. This research offers a significant and timely contribution to both researchers and practitioners in the form of challenges and opportunities where we highlight the limitations within the current research, outline the research gaps and develop the questions and propositions that can help advance knowledge within the domain of digital and social marketing.  相似文献
