A case study analysis of a constructionist knowledge building community with activity theory

This article investigates how activity theory can help research a constructionist community. We present a constructionist activity model called CONstructionism Through ACtivity Theory (CONTACT) model and explain how it can be used to analyse the constructionist activity in knowledge building communities. We then illustrate the model through its application to analysing the Wiki-supported community associated with a computer game. Our analysis focuses mainly on two perspectives: individual and collective actions, as well as individual and collective mediations. Experiences and challenges from the analysis are reported to demonstrate how CONTACT is helpful in analysing such communities.

Overheating in Scotland: contributing factors in occupied homes

ABSTRACT

There is growing awareness of the overheating risks in new-build properties in the UK. However, this tends to be considered a problem principally for the southern regions in the UK, only becoming a serious issue in the north of England in the medium-term and in the long-term for Scotland. This notion tends to be largely predicated upon climate change predictions, differences in latitude and summer air temperatures. This paper describes the results from Building Performance Evaluation (BPE) studies over a two-year period from 26 occupied new-build homes across Scotland which demonstrated incidences of overheating. Results suggest that low-energy buildings are susceptible to overheating despite northerly latitudes, with 54% of houses studied overheating for more than six months annually, and 27% of homes overheating for less than 10% of the year. Evidence indicated that commonly used prediction tools do not appear to anticipate overheating adequately. This paper maps common overheating causes due to design and the role of occupants, identifying the risks due to the regulatory system, prediction and procurement processes, and design and construction. A common finding was that design and occupancy factors appear to have a greater impact on overheating more than location and climatic factors.

浙江农宅平面信息域统计分析——以绍兴市为例

为探究长三角地区农宅平面尺寸在宏观区域上的统计规律,基于Google Earth探向功能,以长、宽作为农宅平面尺寸的标示参量,应用频数统计法分析农宅长、宽在环向及径向分析路径上的频数分布特征。统计结果表明:不管是在环向,还是在径向上,农宅长度都是以3到4个自然开间尺寸的占比最大,农宅宽度都是以2到3个自然开间尺寸的占比最大;在环向上,各区域农宅长度、宽度的频数分布较为相似,且其主要占比区间相对稳定,农宅长度在3到4个自然开间尺寸所占比例约为51%,宽度以2到3个自然开间尺寸为主,其比例为70%左右;在径向上,各区域农宅平面尺寸在各开间的比例差异较大。上述方法与结论对区域视角下的农宅节能潜力分析及既有建筑节能改造策略等问题的研究具有方法借鉴与理论指导意义。
