Johnson, PE Member ASHRAE ABSTRACT This paper is about the application of Mixed Methods for design professionals and social science researchers. The purpose is to describe an intellectual commons which int

Once described, the proposed intellectual commons would include a form of communication based on data described by symbolism and logic to be shared by the broad range of worldviews in our

Second, use standard symbols that appeal to a broad spectrum of worldviews. Third, use the symbols and diagrams to support the narrat

Designers of the built environment have made great strides towards efficiency, but we are running out of physics. The next path towards s

Thus it is proposed that engineers meet the social scientists at the entrance to this new intellectua

INTRODUCTION The distance between logical paths in the physical and social sciences is very small at numerous points on the road to environmental stewardship. The most important thing I learned in my early

12、 studies of qualitative and mixed methods research design is that bridges may be built along these paths on a foundation of diagrams, scales, and symbolism. Mixed Methods is about 25 years old and is still evolving in terms of philosophical assumptions and research methodology. Focusing on the metho

Their work typically involves a hypothesis, the measurement of variables, statistical analysis, and an interpretation of results. In thi

We define the goals, describe a plan, execute the plan, and then compare the result with what was originally in

Assuming these substitute quantitative elements can be incorporated into a valid mixed methods design, our next
