  abstract       = {An important, but relatively neglected, aspect of
                   social stratification in modern societies is the
                   reputational status associated with complex
                   organizations in interdependent organizational fields.
                   In this study, social factors influencing the
                   reputational status of research organizations in
                   large-scale, cognitively diverse, multisectoral
                   "technical systems" are examined. Data are drawn from
                   interviews with personnel from a national U.S. sample
                   of 50 organizations engaged in research on
                   nuclear-waste management and 47 organizations involved
                   in photovoltaics research. The reputational status of
                   each organization was assessed by knowledgeable
                   respondents from other organizations in each system. A
                   model is presented that characterizes reputational
                   status as a function of organizational performance,
                   organizational structure, and network position. Support
                   is obtained for the model by the use of both subjective
                   and objective indicators, including evidence of the
                   mediating effects of network position. Further results
                   obtained from a blockmodel analysis indicate that ties
                   to specific blocks are a more important determinant of
                   reputational status than block membership.},
