Most of the time, humans do not watch their steps when walking, especially on even grounds. They walk without thinking. How robust is this strategy? How rough can the terrain be to walk this way? Walking performance depends on the dynamical contribution of each part of the body. While it is well known that the head is stabilized during the motions of humans and animals, its contribution to walk...

This paper provides some context for my paper which won the 2004 Jay Wright Forrester award. It describes the system dynamics challenges I received from a number of people and my response to them, particularly to explore the issue of mismatch in organisations between process and boundary structure. It also describes how I have been using generic archetypes in practice since publication of the o...

Today s problems often arise as unintended consequences of yesterday s solutions. Social systems often suffer from policy resistance, the tendency for well-intentioned interventions to be defeated by the response of the system to the intervention itself. The field of system dynamics, created at MIT in the 1950s by Jay Forrester, is designed to help us learn about the structure and dynamics of t...

One of the biggest obstacles to expanding the use of information technology (IT) in health care may be the current narrow focus on how to stimulate its adoption. The challenge of thinking of IT as a tool to improve quality requires serious attention to transforming the U.S. health care system as a whole, rather than simply computerizing the current setup. Proponents of health IT must resist "ma...

In the early stages of design, several concepts are usually generated to explore the possibilities. This paper investigates how well a computer-based system can support design thinking. SESAME is a novel 3D design system that aims to support creativity during the explorative phase of the design process. We report an evaluation comparing SESAME to paper sketching for early design exploration in ...

the purpose of this article is to determine elements of strategic thinking in the context of iranian organizations and to find out the interactions and relationships among determined elements. a literature review and also in-depth interviews with experts are conducted to identify strategic thinking elements. interpretive structural modeling methodology is used for analyzing and determining the ...
