Circular Dichroïsm

Using the semiclassical approach for the description of the propagation of the electromagnetic waves in optically active isotropic media we derive a new formula for the circular dichroism parameter. The theory is based on the idea of the time damped electromagnetic wave interacting with the molecules of the sample. In this theory, the Lambert-Beer law need not be taken as an empirical law, however, it follows naturally from the requirement that the electromagnetic wave obeys the Maxwell equations.

Special Relevance

Different notions of multiple rationalities have recently been applied to describe the phenomena of co-existence of competing rationalities in organizations. These include institutional pluralism, institutional logics, competing rationalities and pluralistic contexts. The French pragmatic sociologists Luc Boltanski and Laurent Thévenot have contributed to this line of research with a sophisticated theoretical framework of orders of worth, which has been applied in an increasing number of empirical studies. This article explores how the order of worth framework has been applied to empirical studies of organizations. First, I summarize the basic ideas of the framework, stressing the aspects of special relevance for studies of organizations. Second, I review the empirical studies focusing on the coexistence of competing orders of worth in organizations showing that the order of worth framework primarily has been related to three main themes in organizational research: non-profit and co-operative organizations, inter-organizational co-operation, and organizational change. Third, I discuss how the pragmatic, process-oriented aspect of the research program, focusing on the intertwining of values and action in various forms of ‘justification work’, has been translated into empirical studies. I argue that even if highly interesting empirical studies have begun to appear on the pragmatic aspects of the order of worth program, empirical studies of ‘justification work’ may be a potentially very promising focus for future empirical studies.
