The Evolution of Organizations: Suggestions from Complexity Theory About the Interplay Between Natural Selection and Adaptation

There has been much debate in the managementliterature between neo-Darwinists (who believe in thenatural selection of populations of organizations) andadaptationists (who contend that changes in organization structure and behavior occur in response to theenvironment). The general thesis of neo-Darwinism isthat species are blindly selected for survival by theenvironment. The latest empirical support for the dominant neo-Darwinism perspective adopted bymost biologists is based primarily on the experimentsconducted by Salvador Luria who claims to haveconclusively demonstrated that genes mutate randomly.Recently, however, biologists have re-examined Luria sresearch methods and, after replications of hisexperiments, now question some aspects of the validityof his results. Moreover, there is now new researchwhich provides support for the earlier adaptationistposition, namely, the existence of evolutionary driversand directors existing within self-organizing systems.Of particular importance to the present study is the experimental indication thatself-organizing systems play a conscious role in theirown evolution. We propose that similar mechanisms orprocesses operate in organizational adaptation, thuspointing toward a theoretical modification ofneo-Darwinism that embraces both adaptation and naturalselection in a general, unified theory.     

Visual evaluation using microcomputer-based imaging technology

Microcomputer-based imaging technology reestablishes the direct link between evaluation and environmental design by allowing evaluators and urban designers to visually explore and prospectively evaluate alternative simulations of design proposals. This article describes the microcomputer hardware and software used to create simulations and how these simulations are being used in planning education at the author's university. Imaging technology is presented as a useful and promising addition to the existing repertory of evaluation techniques.     

Sensitivity to bodily nonverbal communication as a factor in practitioner-patient rapport

The relationship between physicians' nonverbal sensitivity and the satisfaction of their patients was tested in two field studies. In the first study, 40 physicians were given a film test of nonverbal sensitivity (the PONS test) and were evaluated by their patients. The second study was a replication using 31 additional physicians. Most noteworthy for research in therapeutic interaction, the present studies contained three methodological advances: (1) the use of actual patients' ratings of satisfaction with treatment, (2) the extension of research from psychological to medical settings, and (3) the use of a standardized test of nonverbal decoding skill. Physicians' skill at reading the emotion conveyed through the nonverbal channel of body movement was found to be significantly correlated with their interpersonal success with patients in the clinical setting.The authors would like to thank Donald Dickson, M.D., Mary Ann Spadaro, M.D., Louise M. Prince, John L. Helmuth, Jr., Helene M. Murphy, and the physicians and patients who participated in the research. Study I was supported by a Peter B. Livingston Fellowship from the Massachusetts Mental Health Center and Study II by a W. K. Kellogg Fellowship from the Hospital Research and Educational Trust, both to the senior author.     

Is obesity stigmatizing? Body weight, perceived discrimination, and psychological well-being in the United States

We investigate the frequency and psychological correlates of institutional and interpersonal discrimination reported by underweight, normal weight, overweight, obese I, and obese II/III Americans. Analyses use data from the Midlife Development in the United States study, a national survey of more than 3,000 adults ages 25 to 74 in 1995. Compared to normal weight persons, obese II/III persons (body mass index of 35 or higher) are more likely to report institutional and day-to-day interpersonal discrimination. Among obese II/III persons, professional workers are more likely than nonprofessionals to report employment discrimination and interpersonal mistreatment. Obese II/III persons report lower levels of self-acceptance than normal weight persons, yet this relationship is fully mediated by the perception that one has been discriminated against due to body weight or physical appearance. Our findings offer further support for the pervasive stigma of obesity and the negative implications of stigmatized identities for life chances.
