Learning in Retirement and Old Age: an agenda for the 21st century

This article is about education and learning for the ‘retired’. In using this term, it is recognised that any such definitions and given age bands cover a wide range of situations and learning needs. Such diversity should closely inform the educational agenda for older adults, and as it is a life phase defined by challenge and change ‘learning to be’ encapsulates much that is essential to that agenda. The international evidence shows how rapidly our societies are ageing, and how much longer is spent in retirement: so rapid is that change and so large the numbers of seniors and the elderly that the active nature of learning represents a critical aspect of response to this major phenomenon. Contrary to a popular image of declining skills and capacities, the evidence reveals a much more nuanced picture of capability among the retired. Comparisons are drawn with the early childhood sector, which had parallel characteristics but which has since moved rapidly upwards among policy priorities. In conclusion, the article argues that ‘active ageing’ rather than ‘lifelong learning’ represents a more promising embracing framework through which to develop learning in retirement and old age.     

Unders and Overs: Using a Dice Game to Illustrate Basic Probability Concepts

In this paper, the dice game Unders and Overs is described and presented as an active learning exercise to introduce basic probability concepts. The implementation of the exercise is outlined and the resulting presentation of various probability concepts are described.     

压力与学习的互惠:对积极塑造者假说的纵贯实证检验

引入积极塑造者假说阐释工作压力与员工学习间的互惠关系,构建二者的良性循环,并据此提出两项中介假设;以研究院所、管理咨询机构的知识型员工为样本,采用两期107份纵贯样本进行回归分析;结果显示,员工学习中介工作压力与工作资源之间的正向关系,工作资源中介员工学习与工作压力之间的负向关系,压力与学习构成良性循环;研究表明,面对压力,积极塑造者将展开适应学习,习得知识后,积极塑造者将改变工作、获取资源以缓解压力,工作压力与员工学习良性互惠、员工福祉和技能螺旋上升。     

基于非线性形状先验的高分辨率遥感图像目标提取方法

对已知目标形状,利用核主成分分析方法非线性建模,并根据高分辨率遥感图像特点,提出一种新的融入形状先验、图像边缘、颜色以及阴影信息的目标提取方法.该方法构造了基于活动轮廓模型的能量函数,并通过迭代的全局最优化方法最小化,实现对目标的准确分割提取.实验结果表明,该方法不仅能准确高效分割提取目标区域,而且能抵制背景噪声干扰,具有很强的鲁棒性和实用价值.

Citizenship education ‘goes global’: extra-curricular learning in an overseas campus of a British civic university

Active citizenship is increasingly being framed in the context of lifelong and life-wide learning. However, research on young people’s participation in and experience of different forms of civic practice, particularly in informal settings in different sociocultural contexts, is scarce. Consequently, little is known about how these experiences shape their learning about active citizenship, their understanding of the self and their relationship to society. This paper reports findings from a small-scale qualitative research on students’ experiences of participation in extra-curricular activities (ECAs) in a UK Transnational Higher Education institution in China, in relation to the development of active citizenship and lifelong learning capacity. The findings suggest ECAs can provide opportunities for students to accumulate knowledge and develop skills, attitudes and values that underpin the promotion of active citizenship, while developing habits and skills essential for lifelong learning.     

GiveMe Shelter: a people-centred design process for promoting independent inquiry-led learning in engineering

It has become increasingly common for tasks traditionally carried out by engineers to be undertaken by technicians and technologist with access to sophisticated computers and software that can often perform complex calculations that were previously the responsibility of engineers. Not surprisingly, this development raises serious questions about the future role of engineers and the education needed to address these changes in technology as well as emerging priorities from societal to environmental challenges. In response to these challenges, a new design module was created for undergraduate engineering students to design and build temporary shelters for a wide variety of end users from refugees, to the homeless and children. Even though the module provided guidance on principles of design thinking and methods for observing users needs through field studies, the students found it difficult to respond to needs of specific end users but instead focused more on purely technical issues.

积极财政政策对区域经济增长与差异的影响

本文利用面板数据模型和时变参数模型分别考察了积极财政政策对我国区域经济增长和差异的影响。分析表明,积极财政政策对我国区域经济增长具有较强的促进作用,其中对西部地区的正向影响力度最大,中部地区次之,东部地区最小。积极财政政策并没有有效地缩小我国区域经济差异,反而促使我国区域差异进一步增大,但影响力度逐年减弱。
