Open journal of Nursing 2017年第2期7卷 222-241页

作者： Gail j. mitchell F. Beryl Pilkington Isolde Daiski Nadine Cross Faculty of Health School of Nursing York University Toronto Canada

This paper describes the kind of engagement and emergent learning that happened in three different sections of a graduate nursing course. Three nursing educators used an e-learning platform called Daagu that was developed by faculty guided by complexity pedagogy. A total of 43 students were enrolled in the full credit foundations course in theory and philosophy. Authors describe two specific instances of emergent learning: one was expressed by students in relation to a particular resource (article, TedTalk, YouTube, Poem) or discussion, and the second is in relation to specific “aha moments” or shifts in understanding that changed student attitudes and actions. Quotes of emergent learning provide a source of narrative data for conversing about and developing quality e-learning platforms for students and educators.

Based on a previous survey on prosthetics and orthotics training in occupational therapy (OT) [1], we developed a 14-question online questionnaire that was made available to the directors of 167 occupational therapy programs (Masters and Ph.D.) in the US and Canada. Fifty- two surveys were completed for a response rate of 31%. Overall, the results indicated that since the previous survey, little has changed in the amount of time and emphasis OT faculty assign to providing training in prosthetics and orthotics, or in the training experiences, OT students receive. Notably, only a few hours of the total OT curriculum is devoted to training in prosthetics. For the majority of programs (62%) the content was embedded within related classes. Only 32% of programs had a required lecture in prosthetics/orthotics. Despite the lack of time given in the curriculum, 85% of program directors thought that training in prosthetics/orthotics was important or very important. The use of prosthetic simulators was reported as the single most desirable training tool. However, lack of time and overcrowding in the curriculum were cited as the greatest barriers to providing more training to students. We elaborate on these findings, discuss their implications for OT students and practitioners, and provide specific recommendations about how to overcome the barriers and enhance upper limb amputee exposure and knowledge through the prosthetic training experience.

在目前的工业化生产系统中，几乎所有的家禽一生中至少需要经过2次运输，少则几公里，多的需要若干小时的路程。大部分禽类运输通过公路进行，也有一些是采用空运或海运的方式。运输程序和集装箱微环境的不同，将会导致家禽在运输过程中产生相应的应激反应，这些应激反应会导致其福利状况、健康状况和生产性能的改变，这就要求对以上条件进行改进和提高。

云分布的变化会对气候变化产生一个重要反馈。大气环流模式模拟表明在气候变暖时高云向上移动,自由对流层云总的说来减少。高云的移动可能是由对流层顶的向上移动引起的。据认为相对湿度及下部云量的减少可以归因于较暖气候条件下垂直运动的厚度增加,并且由于比湿增加大气辐射冷却也会向上移动。关于大气环流模式响应的诊断研究结果与这种机制是一致的。
