研究目的:探究城市居民小汽车交通行为变化的原因有多少来自人口统计特性的变化,有多少来自城市结构的改变。
创新要点:考虑家庭成员的生活任务分工以及家庭资源的分配等对每个家庭成员出行方式的影响,构建基于家庭生命周期的小汽车出行行为模型,为控制小汽车出行对策的研究提供准确依据。
研究方法:采用调查与统计理论,掌握居民的出行行为特征;基于经济计量学建模方法,构建居民小汽车出行行为联立方程模型。重要结论:城市结构关系的改变在抵消了人口统计特性的变化对小汽车交通产生的负面影响之后,小汽车交通总体呈上升趋势。 相似文献

This study examined the views of advertising academics regarding the peer‐review process in English‐language advertising journals. Three issues were examined. First, how do advertising academics assess the peer‐review process in advertising journals on the following dimensions: fairness, anonymity (truly double‐blind), timeliness, and effectiveness in improving the quality of research? Second, how do they perceive the ethicality of review process behaviors? Third, what steps do they suggest for improving the quality or integrity of the peer‐review process? Data was collected through a survey of US‐based advertising academics. The findings reveal that advertising academics believe that, for the most part, advertising journals are succeeding at fairness, protecting anonymity, improving the research of submitters, and avoiding ethical infractions in the review process. However, advertising academics would like to see improvements in timeliness as well as in incentives and guidelines provided to participants in the peer‐review process. 相似文献

Abstract The influence of exercise mode and practice qualities on the stress reduction benefits of exercise was examined. College students in swimming, body conditioning, hatha yoga, fencing, exercise, and lecture-control classes completed the Profile of Mood States and the State Anxiety Inventory before and after class on three occasions. Swimmers had unusually positive initial moods and reported less tension and confusion after swimming only on the first day of testing. Participants in yoga, an anaerobic activity that satisfied three of the four mode requirements, were significantly less anxious, tense, depressed, angry, fatigued, and confused after class than before on all three occasions. Supporting the importance of the four mode characteristics, participants in the exercise control activity of fencing reported improvements only in vigor. A possible influence of practice conditions was observed when members of the body conditioning class reported significant increases in fatigue, but no other mood changes. Results of this study supported the possibility that exercise mode and practice requirements in the proposed taxonomy moderate the stress reduction benefits. 相似文献

Anatomical examinations have been designed to assess topographical and/or applied knowledge of anatomy with or without the inclusion of visual resources such as cadaveric specimens or images, radiological images, and/or clinical photographs. Multimedia learning theories have advanced the understanding of how words and images are processed during learning. However, the evidence of the impact of including anatomical and radiological images within written assessments is sparse. This study investigates the impact of including images within clinically oriented single-best-answer questions on students' scores in a tailored online tool. Second-year medical students (n = 174) from six schools in the United Kingdom participated voluntarily in the examination, and 55 students provided free-text comments which were thematically analyzed. All questions were categorized as to whether their stimulus format was purely textual or included an associated image. The type (anatomical and radiological image) and deep structure of images (question referring to a bone or soft tissue on the image) were taken into consideration. Students scored significantly better on questions with images compared to questions without images (P < 0.001), and on questions referring to bones than to soft tissue (P < 0.001), but no difference was found in their performance on anatomical and radiological image questions. The coding highlighted areas of “test applicability” and “challenges faced by the students.” In conclusion, images are critical in medical practice for investigating a patient's anatomy, and this study sets out a way to understand the effects of images on students' performance and their views in commonly employed written assessments. 相似文献

This paper contributes a definition of mobile literacy. This is worthwhile because although mobile, internet‐enabled devices are increasingly prevalent in many people's lives, mobile literacy appears to be under‐theorised and lacking definition. After giving an overview of the scale and nature of mobile device use, the paper develops the definition through building on an existing body of work which seeks to define literacies, digital literacies and mobile learning. The definition takes account of the mobility of technology, of learners, and of learning. A systematic multimodal analysis of a complex undergraduate text, in the form of a conference‐style poster, is then undertaken in order to exemplify the definition offered. The analysis attends to both the semiotic resources exploited by the text's author and the wider context the text is created within. Interview data complements that constructed through analysis of the text itself. Combining these two data sources reveals the ideational, interpersonal and textual/organisational meanings communicated by the text, and how mobility is a contextual factor which is fundamental to the literacy practices employed by the author to convey these meanings. 相似文献

Predatory publishers—those who do not adhere to rigorous standards of academic practice such as peer review—are increasingly infiltrating biomedical databases, to the detriment of the wider scientific community. These publishers frequently send unsolicited ‘spam’ emails to generate submission to their journals, with early career researchers (ECR) particularly susceptible to these practices because of pressures such as securing employment and promotion. This analysis sought to record and characterize the emails received over the course of a PhD and post-doctoral position (~8 years), as well as attempts to unsubscribe from such emails, using a progressive and step-wise manner. A total of 1,280 emails identified as academic spam were received (990 journal invitations, 220 conference invitations, 70 ‘other’). The first email was received 3 months after registration for an international conference. Attempts at unsubscribing were somewhat effective, whereby implications of reporting to respective authorities resulted in a 43% decrease in emails, although did not eliminate them completely, and therefore alternative approaches to eliminating academic spam may be needed. Ongoing education about predatory publishers, as well as action by key academic stakeholders, should look to reduce the impact these predatory publishers have upon the wider literature base. 相似文献
