Group Model Building Wins: The results of a comparative analysis
نویسندگان
چکیده
This paper presents clear evidence of the value of group model building for supporting group decision processes. It responds to Rouwette et al.’s (2002) challenge to take GMB assessments beyond unstructured single case descriptions that cannot be easily compared. This paper compares two parallel, real-world problem solving teams examining urban growth issues in Las Vegas, Nevada over the same two-year time period. One followed a system dynamics group model building process. The other used a more traditional group facilitation process. Data about the dynamics of discussions and the outcomes were collected from meeting transcripts, participant interviews, written documents and direct observations. The results reveal a marked difference in the content and timing of discussions over the life of each group project, strongly supporting the hypothesis that system dynamics provides a better foundation for structuring discussions, eliciting mental models, and generating sound decisions.

Background: Thirteen (13) types of building tiles and Sharp sand commonly used for building purposes were collected for their radionuclide contents analysis. Both imported and locally produced building tiles were examined. Materials and Methods: The samples of tiles and sand were crushed to powder and they were prepared such that their content could be examined by the use of gamma-ray spectrom...
متن کاملDetermination of Refractive Index and Confinement Losses in Photonic Crystal Fibers Using FDFD Method: A Comparative Analysis
In this paper, we present a comparative numerical analysis to determine the refractive index of photonic crystal fibers (PCFs) by using FDFD method and used the results to evaluate the confinement losses of PCFs by considering the effects of air-hole rings in the cladding. It is shown that by increasing the wavelength, the imaginary part of refraction index rises, resulting in increase of conf...

Designing a Public-Private Partnership Model for Public Hospitals in Iran
Background and Objectives: Public-Private Partnership (PPP) is a well-established model to alleviate the risk of investment in health domain. While the model is widely applied in the developed countries, the adoption of the model in many developing countries is hampered partly by the lack of knowledge on dimensions and requirements of its local implementation. The present study...
