数字图像处理课程教学方法研究

本文针对数字图像处理课程章节多、算法复杂、学科跨度大、知识体系庞大的特点,提出了基于内容关联性的课时规划方法、基于权重的算法学习法、基于期望目标的仿真软件选择法以及关键问题多角度诠释的方法来提升教学及学习效果。实践表明,这些教学方法的实施对数字图像处理课程教学具有良好的效果和积极的现实意义。     

基于Pro/Engineer机构运动分析在机械原理课程中的运用

机械原理课程具有理论性强、概念抽象、涉及的基础理论和知识面广、系统性强等特点,在机械原理课程的学习中,引入Pro/Engineer软件进行机构仿真能够让学生牢固地掌握好机械原理这门课程。本文首先介绍在机械原理课程中引入三维CAE运动仿真的重要性,其次简介Pro/Engineer Mechanism模块的主要功能和机构运动学的工作流程,最后介绍在教学中如何运用Mechanism模块建立连杆机构的装配模型、进行仿真运动分析和获得运动轨迹和包络图等相关数据。实践证明,在机械原理教学中引入Pro/Engineer Mechanism模块进行机构运动学分析不仅能够帮助教师改善课堂教学效果和激发学生的学习兴趣,而且在优化机构、提升机构运行可靠性方面都有着十分重要的应用价值。     

公共图书馆立足于数字化时代的合理性

在新兴数字技术的冲击下,公共图书馆经历着蜕变,在其遭遇威胁的同时,也面临着转机。本文透过维多利亚州立图书馆等案例解析,从理性的角度俯视数字化环境下的种种争论。可以发现,图书馆是由公众资金支持的机构,服务民众是其不可推卸的使命。因而,为了保证图书馆立足于数字化时代的合理性,我们必须透视技术的本质,了解民众的真正需求。     

Analysing the professional development of teaching and learning from a political ethics of care perspective

This paper uses Tronto's political ethics of care as a normative framework to evaluate a model of teaching and learning professional development. This framework identifies five integrated moral elements of care – attentiveness, responsibility, competence, responsiveness and trust. This paper explicates on each of these elements to evaluate the piloting and implementation of a teaching and learning professional development model at a South African higher education institution. The political ethics of care was found to be a useful normative framework for a group of higher educators to reflect on the process of engaging in teaching and learning professional development in that it revealed the importance of differential power relations, the importance of working collaboratively and being attentive to the needs of both caregivers and care receivers.     

The Role of Artists in Sites for Learning

Socially engaged, participatory and educational arts activities have been recognised by artists as a legitimate area of creative practice for a considerable time. Current policy initiatives around social inclusion and life long learning demonstrate that this government has a keen interest in the transformative nature of creativity and participation in arts activity. This paper explores the significance of the, Arts Council's Artists in Sites for Learning Scheme and a related piece of research within the context of recent cultural agendas and governmental policy initiatives. The research examined the ‘forms of engagement’ that occur between artists, participants and others and concludes that the role the artist inhabits within this form of creative practice is multifaceted and highly sophisticated. This paper also raises key issues concerning the ‘value’ and critical assessment of this form of practice and the need for appropriate support for (and evaluation of) it in the future.     

Fair dealing for criticism and review in scholarly publishing

UK Copyright law (CAPD 1988) defines the requirements for qualification for copyright protection in the UK and for many of the permitted acts. A defence against infringement of copyright is provided for under the terms of fair dealing for the purposes of criticism and review, but use of this defence must be assessed on the nature and extent of the use of copyright material in each case. Industry practice and guidelines exist for use of some text material, but not for the fair dealing use of other copyright material such as images and artwork, the inclusion of which was a major change in the CAPD 1988 act from earlier UK copyright acts.
