This essay explores the practice of “culture jamming” as a strategy of rhetorical protest. Specifically, “pranksters” deploy the tools of the mass media and marketing in order to take advantage of the resources and venues they afford. Through the concept of “pranking,” this essay suggests that the most promising forms of media activism may resist less through negation and opposition than by playfully appropriating commercial rhetoric both by folding it over on itself and exaggerating its tropes.  相似文献

This study examined associations between bedroom television, media use, and adolescents' health risk behaviors. A sample of 1,017 12- to 14-year-old adolescents completed computer-assisted interviews at baseline and 2-year follow-up. Among White adolescents, having a bedroom television predicted risk-promoting media use practices and significantly greater odds of initiating health risk behaviors—cigarette smoking and sexual intercourse—over 2 years. Although significantly more Black than White adolescents had a bedroom television, bedroom television was unrelated to Black adolescents' media use practices or health risk behaviors. Research is needed to understand ethnic differences in family media use and consequences for adolescent development.  相似文献

ABSTRACT

A research project was undertaken by a university library system to develop a sustainable user experience strategy. A task force was convened to conduct a pilot project with members from both libraries in the system to assess staffing responsibilities, guidelines, processes, and data-gathering procedures. The team tested an electronic resources list common to both libraries. In describing the methods employed by the task force in their research, this article outlines the benefits and drawbacks of staffing configurations to initiate user experience practices in an academic library setting.  相似文献

The purpose of this study was to determine whether workplace reproaches differ in their level of perceived face threat and to examine the relationship between perceived face threat and a variety of outcomes. One hundred and four full‐time employees completed a survey asking them to describe in detail a time they were reproached by a manager. The survey included scales measuring perceived face threat, interactional fairness, anger, communicative competence, and satisfaction with the outcome of the incident. As predicted, we found that reproaches differ from each other in degree of perceived face threat. In addition, perceived face threat was negatively correlated with interactional fairness, communicative competence, and satisfaction with the outcome of the incident, and positively correlated with anger.  相似文献

The integration of librarians into allied health programs presents many exciting opportunities for collaboration. This column will describe how a library instruction program is integrated into the occupational therapy, respiratory care, and physical therapy curricula at the University of Texas Health Science Center at San Antonio. The allied health faculty have welcomed and recognized the librarians’ expertise in teaching evidence-based practice and library research skills.  相似文献

The United States National Library of Medicine (NLM) has the largest collection of biomedical information products and services in the world. Little is known of the extent to which librarians in sub-Saharan Africa are aware of and use these resources. The study's aim was to assess knowledge and frequency of use of NLM's biomedical information products and services among African librarians. Forty-three of the 50 delegates at the 11th biannual Congress of the Association of Health Information and Libraries in Africa (AHILA) participated in the study. The findings showed that participants' knowledge of NLM information products and services was low and that there is a need for increased awareness and training in the use of NLM's information products and services in order for users on the African continent to effectively benefit from them.  相似文献

Librarians have traditionally facilitated research development resulting in grants through performing biomedical literature searches for researchers. The librarians at the Taubman Health Sciences Library of the University of Michigan have taken additional steps forward by instituting a proactive approach to assisting investigators. To accomplish this, the librarians have taken part in a collaborative effort with the University of Michigan Medical School Office of Research. Through this partnership, both units have created and adopted various techniques intended to facilitate the submission of grants, thus allowing researchers more time to conduct their primary activities.  相似文献

The purpose of this paper is to critically evaluate the use of action research as a tool for developing critical reflection which has the potential to lead to change and development in practice in education, in particular, in the area of special educational needs (SEN) and inclusion. In order to support and illustrate the critique, a case study of a group of Dutch practising teachers and education professionals engaged in studying for a master's degree in SEN is used. The three-year programme of study followed by the group was a practice-based programme of professional development, with heavy emphasis on action research throughout. For this particular group action research was an entirely new concept, and indeed many of them expressed considerable scepticism about its validity as an approach to research, or for that matter, professional development, at the beginning of the programme. The whole group were working in areas associated with SEN where the need to change practice was an urgent imperative, due to changes in education policy and the rapid move towards inclusion in The Netherlands. Having been responsible for the development and teaching of the programme for several years, I decided to make a case study of one cohort of students in order to carry out some more structured and detailed evaluation of the impact of the programme on practice. I also wanted to reaffirm the general impression I had gathered from continuing student evaluation and feedback, that their work, and in particular the action research they had carried out, had led to genuine development and, in some cases, fairly radical change in their professional practice.  相似文献

Since the late 1990s, there has been consensus among educational researchers that argumentation should play a central role in science education. Although there has been extensive relevant research, it is not clear enough how oral argumentation spontaneously occurs in science teaching. This is particularly important with regard to the empirical evidence suggesting the effect of discussion of contradictory views on scientific learning. In order to contribute to the research on argumentation in science teaching, we conducted a study that aims to sketch a panoramic view of the uses of oral argumentation in Chilean middle-school science teaching. A total of 153 videotaped science lessons were observed, involving students aged 10–11 and 12–13. Whole-class argumentative discourse was analysed as a function of thematic episodes and teachers' and students' utterances. Results suggest that argumentative discourse in which contradictory points of view are discussed is scarce but when it occurs it does so predominantly within discourse among students. On the contrary, argumentation aimed at justifying points of view is widely used, even more so when students are older.  相似文献

Few studies have empirically investigated the specific factors in mentoring relationships between undergraduate researchers (mentees) and their mentors in the biological and life sciences that account for mentees’ positive academic and career outcomes. Using archival evaluation data from more than 400 mentees gathered over a multi-year period (2005–2011) from several undergraduate biology research programs at a large, Midwestern research university, we validated existing evaluation measures of the mentored research experience and the mentor–mentee relationship. We used a subset of data from mentees (77% underrepresented racial/ethnic minorities) to test a hypothesized social cognitive career theory model of associations between mentees’ academic outcomes and perceptions of their research mentoring relationships. Results from path analysis indicate that perceived mentor effectiveness indirectly predicted post-baccalaureate outcomes via research self-efficacy beliefs. Findings are discussed with implications for developing new and refining existing tools to measure this impact, programmatic interventions to increase the success of culturally diverse research mentees and future directions for research.  相似文献
