Enhancing the practice of social work

This account of practice focuses on my learning and development as a new Action Learning Facilitator. It reflects on my thoughts and feelings as I began to facilitate my own sets a year or so ago. It will discuss and reflect on topics such as communication, feedback, expectations (both mine, the set members and the organisations), values, ethics, power and confidentiality. It opens with a personal reflection on my experience of becoming a set facilitator and then explores other aspects of my learning. It draws out, in particular, the links between Action Learning and social work and the ways in which the principles that underpin each of these are complementary and mutually enhancing.     

自足的性状小句与成活的性状小句

本文把性状小句分为自足的性状小句和成活的性状小句,分别考察了自足的性状小句中的程序范畴和成活的性状小句成活的方式,并探讨了两种类型小句在使用上的差异。文章末尾有一个余论。     

四能级原子自发辐射的量子相干特性

研究四能级原子的自发辐射。原子激发态是不稳定的,其必然会自发地向低能级衰变,产生自发辐射现象。本文针对四能级原子仅存在自发辐射的情况,基于量子力学和Kraus算子理论,利用约化密度矩阵方法,得到四能级原子自发辐射的密度矩阵元演化规律,从而分析量子态相干特性。     

Enhancing the facilitation of online groups in higher education: a review of the literature on face-to-face and online group-facilitation

There still appears to be a gap between what online learning promises and what it can deliver in terms of student learning. Developments in online pedagogies and professional learning appear to lag behind the developments in technology and the promised benefits of technological transformation may not be realised. In this paper, we bring together perspectives that highlight vital aspects of online group-learning by reviewing the group-facilitation literature and the latest online learning literature to interrogate the pedagogical theories and practices currently used in online group-learning in higher education. We specifically focus on the interpersonal interactions between teachers and students, which are described in the online learning literature using the terms instructor immediacy, teaching presence, and social presence. We note differences in the literature regarding how teacher presence is interpreted and enacted and we expound the importance of the personal characteristics of the online teacher. Finally, we provide some signposts that might help course designers and teachers to improve online group learning: the intentional use of effective online learning pedagogies; a deeper understanding of what constitutes teacher presence; and strategies to enact that teacher presence with online groups. Recommendations for further research in online group facilitation are provided.

How information systems came to rule the world: Reflections on the information systems field

Abstract

Over some seven decades, a rather mundane transition that in its thoroughness and consequences has gone largely unacknowledged, has taken place, namely the revolution in modern information systems (IS) that guide organizations in their actions. Today, it is fair to say that IS have come to rule the world. They do this literally, by the rules they embody, which dictate how much of everyday life, as it relates to individuals and organizations and the transactions they engage in, takes place around the globe. In essence, IS have become important social and economic infrastructure. Seeking an understanding of how this has come about, I review historical developments in IS, focusing in particular on accounting systems, enterprise systems, retail automation, and electronic commerce. I argue that it is transactions and their facilitation that lie at the heart of IS and its development as a field of practice. I reflect on why this has gone mostly overlooked as such. I consider where we have now arrived with transaction facilitation as infrastructure and its importance in the light of current issues. I suggest how future studies might contribute to our learning more about where we should want to be with our transaction facilitation infrastructure.

体育专业学生自带准备活动的实验研究

通过对韩山师范学院体育系01级4个体育本科班的教学改革实验发现:体育专业学生在体育教学中自带准备活动,不仅能激发学生的学习积极性、发挥学生的主体作用、培养学生的参与意识,而且能锻炼学生的组织能力,提高体育教学技能,为教育实习做好准备。     

本体感受神经肌肉促进法（PNF）对提高机体平衡能力的研究

运用文献资料法、数理统计法、对比实验等方法研究本体感受神经肌肉促进法（PNF牵张法）对机体平衡能力的影响。结果显示：实验组和对照组在训练第8周和第16周后,动、静态平衡能力均有较大幅度提高。停训4周后,实验组学生动、静态平衡能力下降。说明运用PNF牵张法有助于改善机体的平衡能力。
