Designing education for life on earth

Designing, viewed broadly as the human capacity to link thought and action, has meaning and value in the world that transcends its material associations. Given the nature and urgency of current socioeconomic and ecological problems, the creative, generative concept of design must be made more accessible and useful. Accordingly, my intent is to dispel prevailing, narrow, specialist impressions of design and to advance in the public mind a larger concept that can influence deliberations and behavior in society-at-large. One of today's most critical areas of need, and one where I think design can make a particularly significant contribution, is education. A critical task for such design-based education is enabling people to design an ecologically and economically sustainable future.     

The meeting place: Qualitative aspects of product environmental assessment

Quantitative methods for evaluating the environmental impact of products are receiving considerable attention. Software is being developed to enable analysis of many aspects of a product's life cycle—from materials' extraction, through manufacture, to use and disposal. Less attention is being paid to the qualitative aspects of products and their significance in addressing environmental concerns. Here, the argument is made for including qualitative evaluations as an important facet of product environment assessment. Such evaluations are essential if significant progress is to be made in alleviating the adverse environmental effects of products. Combined with quantitative analyses, the two approaches become mutually supportive and, ultimately, inseparable.Qualitative environmental assessments can be applied to existing products and at every stage of the design process. Their adoption within the context of professional practice will be fostered by their inclusion, formulation and discussion within design education. This paper describes the basis and nature of these qualitative judgments, and places the qualitative and quantitative in a unified context which points towards more sustainable ways of living. The use of scenarios is discussed as a tool for academic design projects in order to address the complex relationships which might otherwise seem overwhelming to the design student.

Pragmatism, Pedagogy and Philosophy A Model of Thought and Action in Action in Primary Technology and Science Teacher Education

This article reports on one outcome from a three-year study with pre-service primary teachers at Goldsmiths' College, University of London. The purpose of the study was to evaluate the influence of participants' prior educational experience and beliefs about the relationship between design & technology (D&T) and science on their lesson planning for these subjects during school placements. Data from the study support a three-domain model of pre-service teachers' thinking and action. When operating within the pragmatic domain, participants are primarily concerned with survival in the classroom, resulting in short-term planning which may contradict their epistemological and curricular beliefs. In the pedagogical domain, the focus shifts from the pre-service teacher themselves and their immediate survival to the learning potential of the activities they plan. There is evidence that some participants have progressed to operating within a philosophical domain, leading to clasroom practice which reflects and re-conceptualises pre-service teachers' core beliefs about the nature of, and relationship between, D&T and science. This revised version was published online in July 2006 with corrections to the Cover Date.

基尼系数与企业内部薪酬分配合理性研究

本文试图把基尼系数从宏观引向微观，探讨用基尼系数来反映企业内部收入分配的合理性问题。论文先从理论上分析了企业内部影响基尼系数的因素，企业分配政策对基尼系数的影响：然后根据实际数据对三个组织的内部收入分配的基尼系数进行计算，证明了在企业应用基尼系数的可行性：最后得出结论：目前社会上存在的不公平，并不是工资差别引起的，而是由灰色收入、城乡差别、行业差别等其他因素引起的。
