This study focuses on the perceived effectiveness of political satire. A pair of experimental studies using original satirical works offer findings for audience perceptions regarding two types of satire, juvenalian and horatian, compared to traditional opinion-editorial argumentation. The two studies produced replicable findings that indicate clear perceptions of persuasive intent associated with both types of satire, and horatian satire ranking lower than traditional opinion-editorials in perceived message strength and perceived influence on self. 相似文献

The influence of a 12-week-proprioceptive training on functional ankle stability was investigated in young speed skaters. Twenty-eight speed skaters were randomly divided into an intervention (n = 14) and into a control group (n = 14). A 15-min circle training was performed 5 times per week over a 12-week period. Measurements were taken prior to the training, after 6 and 12 weeks of training. Kinaesthesia was evaluated with the Isomed2000 in all movements of the ankle joint. Dynamic balance was tested with the Biodex Stability System at the stable level 8 and at the unstable level 2, measuring the overall stability index, the anterior/posterior and the medial/lateral scores. Static single-leg stance was evaluated using the Kistler force platform. Kinaesthesia of the intervention group improved significantly for plantarflexion of the right foot (P = 0.001) after 12 weeks. Dynamic balance showed significant differences in the intervention group after 12 weeks in comparison with the first measurement for each foot in the overall stability index, the anterior/posterior and the medial/lateral scores (P ≤ 0.017, respectively) at the unstable level 2. Functional ankle stability improved in terms of dynamic balance after 12 weeks of proprioceptive training. Therefore, inclusion of proprioceptive exercises in the daily training programme is recommended for young speed skaters. 相似文献

With the advances in neuroscience in the twenty-first century, there is an increased risk that this research could be used for non-peaceful purposes by state or non-state actors. The latter issue is generally referred to as the dual-use problem, which has created a heated debate among scientists and security experts about the duties and responsibilities of researchers where each side is reluctant to engage with the other in a cooperative manner. In order to break this stalemate, a project on how to improve ethics education for neuroscientists was carried out which led to the development of an open access, online 12-lecture module. This article discusses how the project followed an action research methodology. While theory proposes that action research can either deliver on a practical level or enable emancipation, the article will discuss how this research project managed to accomplish both. Furthermore, it draws on a critique of emancipation in the form of postmodern theory to discuss the emergence of power and its application. 相似文献

Since it was introduced into Europe from South America by the Jesuits at the beginning of the 17th century, quinine has been one of the most effective drugs for the treatment of malaria. During this century a number of synthetic antimalarial drugs have been introduced but while these have had considerable success their extensive and sometimes haphazard use, often as an alternative to vector control, has created serious resistance problems. 相似文献

This article examines the education of library (MLS) graduate students in courses of library management or in special topic courses in project management in libraries and information centers. To examine the specific skill of project management, a method was employed allowing students to set deadlines as a form of self-directed learning. The student-created syllabi milestones were piloted to search for a match between student abilities and development of project management processes upon degree completion. The use of a proposed and piloted technique was implemented here through a tool named the Personal Course Plan (PCP). It was designed to assist students in learning the value of setting personal schedules for their enrolled graduate course, much as a library project manager would use in practice in libraries. Personal Course Plans (PCPs) were effectively developed by students and allowed the ability to self-monitor their performance on completing project deliverables, meeting expectations of supervisors, and judging their own performance. As the experience was a positive one for both the instructor and students, this article provides not only an operational examination, but also proposes theoretical justification for using such a teaching method in library and information science education. Described are details LIS faculty should consider in implementing the method in teaching and gives future library employers of LIS program graduates a sense of what project management skills recent graduates are receiving. 相似文献
