2. Expectation-driven interaction: a model based on Luhmann's contingency approach

Author

Barber, M. J., Blanchard, Ph., Buchinger, E., Cessac, B., and Streit, L.

Subjects
Physics - Physics and Society
Abstract

We introduce an agent-based model of interaction, drawing on the contingency approach from Luhmann's theory of social systems. The agent interactions are defined by the exchange of distinct messages. Message selection is based on the history of the interaction and developed within the confines of the problem of double contingency. We examine interaction strategies in the light of the message-exchange description using analytical and computational methods., Comment: 37 pages, 16 Figures, to appear in Journal of Artificial Societies and Social Simulations

10. Assessing and improving the effectiveness of national research laboratories

Author

Abstract

This paper presents initial work at two U.S. Department of Energy (DOE) national laboratories to develop a process for assessing and improving the effectiveness of research organizations. The approach to assessment reflects the complexity of the research environment and provides information that allows the research organization to define a few key actions for improvement. The work described here focuses on identifying attributes of DOE laboratory research environments that are most important for fostering excellent research. Thirty-six attributes in four areas were identified by scientists and engineers at these institutions and are presented using the Competing Values model for discussing organizational effectiveness. These attributes served as the basis for the development of a self-assessment survey and improvement process designed specifically for research environments. Assessments involving more than 1000 scientists and engineers in four organizations have shown that this approach provides a good basis for understanding and improvement. Index Terms--Assessment, Competing Values, employee attitude survey, improvement process, National Laboratories, organizational effectiveness, research environment, U.S. Department of Energy (DOE).

Abstract

Single-molecule Förster resonance energy transfer (smFRET) is increasingly being used to determine distances, structures, and dynamics of biomolecules in vitro and in vivo. However, generalized protocols and FRET standards to ensure the reproducibility and accuracy of measurements of FRET efficiencies are currently lacking. Here we report the results of a comparative blind study in which 20 labs determined the FRET efficiencies (E) of several dye-labeled DNA duplexes. Using a unified, straightforward method, we obtained FRET efficiencies with s.d. between ±0.02 and ±0.05. We suggest experimental and computational procedures for converting FRET efficiencies into accurate distances, and discuss potential uncertainties in the experiment and the modeling. Our quantitative assessment of the reproducibility of intensity-based smFRET measurements and a unified correction procedure represents an important step toward the validation of distance networks, with the ultimate aim of achieving reliable structural models of biomolecular systems by smFRET-based hybrid methods.

25. AUTOLOGOUS FAT TRANSFER, BREAST LIPOMODELLING AND FAT TRANSFER TO THE FACE: CURRENT GOLD STANDARDS AND EMERGING NEW DATA

Author

Subjects

Abstract

Autologous fat transfer techniques have experienced tremendous boom in the recent years. Plastic surgeons use these techniques to enhance both the features of the face and of the body. Over the years, controversies concerning fat harvesting, fat processing and fat injection came up. The authors of this review article describe their own experience with fat harvesting, processing and injection and show some of their own results. In addition, they discuss contemporary data from literature regarding the use and complications of fat grafting to the most common areas treated with fat grafting: breast and face.
