Institutions of higher education acknowledge that online learning represents a growing segment of the modern learning environment, and most students have mastered basic computer skills. However, reluctance to engage in online learning remains among both faculty and students. This article presents a case study of three schools of nursing that collaboratively developed and implemented an online undergraduate-nursing course. The article discusses the challenges that were encountered by faculty and students. The faculty used the distance education literature to address these challenges related to technological, institutional, and pedagogical aspects of online learning, as well as the recruitment and retention of online learners. Quantitative and qualitative methods were used to evaluate the effectiveness of the course. The paper concludes with suggestions to overcome the challenges of online learning, such that faculty and students receive the inherent rewards.  相似文献

All traumatic and overuse injuries occurring during an average period of 4 years (2002/09) in a group of 51 currently active road top-level cyclists were retrospectively registered through clinical interviews. Average age was 25.8 years. Average training and competition period was 28.3 ± 2.4 h a week. Only 8 cyclists (15.6%) were completely free from lesions during the period of study. The remaining 43 cyclists suffered a total of 112 lesions; however, 9 out of these were unrelated to their cycling practice. These 103 cycling-related injuries include 50 (48.5%) traumatic and 53 (51.5%) overuse injuries. Twenty-eight fractures were reported, the clavicle being the most frequently affected bone (11 cases). The 68.5% of overuse injuries were located in the lower limbs. Most overuse injuries (89.6%) occurred during the training period. According to the injury abbreviated scale (AIS), severe lesions were only found in 4 cases (8% of traumatic injuries). Overall injury rates were 0.50 per racer/year, 2.02 per studied racer, and 0.007 per 1000 km of training and competition. Active professional top-level cyclists are exposed to a high injury risk. According to the scarce previously published data the current study provides relevant information on the injury occurrence of still active top-level road cycling.  相似文献

This paper describes an alternative approach to undertaking and evaluating sexual health promotion, focusing on the notion of sexual scenes and scenarios and how these can provide a vantage point from which to examine sexual experience. The concept of sexual scenes provides a context within which to analyse many of the behavioural and epidemiological factors associated with sexual practice. In principle, such an approach provides a tool for conscientization, action and the invention of novel group and individual repertoires that may result in individual and social mobilization for health and/or sexual and reproductive rights. Scenes can be elicited through individual interviews, group interviews and discussions, or through staged and dramatized performance and students' writing. Analysing sexual scenes offers an entry point for dialogue in sexual health promotion programming. Evaluation of these programmes can be part of the process of changing sexual scenarios. Change is witnessed not only through individual changes but, especially in impoverished communities, through challenges to dominant local sexual scenarios and engagement with structural concerns.  相似文献

Since 1976 in response to growing concern about college students’ writing abilities, faculty development programs on writing across the curriculum have arisen in a number of two‐ and four‐year colleges throughout the United States. This movement, for it seems to be one, has its roots in a similar movement that began more than 15 years ago in British secondary schools. This paper first reviews briefly the early history of the movement in England and compares the movement there to the one now under way in U.S. higher education. It then presents the results of a questionnaire survey of New Jersey's public two‐ and four‐year colleges undertaken in the spring of 1979. The purpose of the survey was to determine whether and to what extent New Jersey's public colleges had started or were planning to start development programs designed to bring groups of faculty together, across disciplines, to discuss problems relating to student writing performance and to develop specific interdisciplinary plans for solving these problems. In addition, information is presented about the nature of the steps taken in those institutions that reported having initiated such programs and about the efforts to evaluate the impact of these programs. Finally, conclusions are drawn about the state of writing across the curriculum programs in New Jersey public higher education and recommendations are made for further action in this direction.  相似文献

ABSTRACT

Previously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO2 was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO2 decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present.  相似文献

The first important monograph describing the battered child syndrome was written in 1860 by Ambroise Tardieu, a French forensic physician. Here is a translation of his article, published in the Annales d'hygiene publique et de medecine legale, with the title "Etude medico-legale sur les sevices et mauvais traitements exerces sur des enfants." The first part of his article is entirely translated. A brief summary of the 32 cases report described by Tardieu in the second part of his article is presented.  相似文献
