In this paper, we examine the evolution of the institutional and intellectual structures of the IS field. We argue that, though the field’s institutional structures—academic programs, journals, conferences, and professional associations— have developed admirably, the state of the field’s intellectual structure is less clear. We employ a co-citation lens to analyze the development and evolution ...

A two-sided, pair-wise matching model is developed to analyse the strategic interaction between two information intermediaries who compete in commission rates and network size, giving rise to a fragmented duopoly market structure. The model suggests that network competition between information intermediaries has a distinctive market structure, where intermediaries are monopolist service provide...

Circadian rhythmicity in humans has been well studied using actigraphy, a method of measuring gross motor movement. As actigraphic technology continues to evolve, it is important for data analysis to keep pace with new variables and features. Our objective is to study the behavior of two variables, interdaily stability and intradaily variability, to describe rest activity rhythm. Simulated data...

Landscape features of anthropogenic or natural origin can influence organisms' dispersal patterns and the connectivity of populations. Understanding these relationships is of broad interest in ecology and evolutionary biology and provides key insights for habitat conservation planning at the landscape scale. This knowledge is germane to restoration efforts for the New England cottontail (Sylvil...

Knowledge management (KM) research lacks a common conceptual core; it is cross-disciplinary, addresses a wide variety of phenomena, and has dif®culty distinguishing itself from many related areas of research. The result is a fragmented ®eld that is itself arti®cially split from the related literature on organizational learning. KM may be progressing through a predictable life-cycle that could e...

We offer a new measure of the ideologically cognizable number of political parties/party groupings that is intended to be complementary to the standard approach to counting the effective number of political parties – the Laakso–Taagepera index (1979). This approach allows the possibility of precise measurement of concepts such as polarized pluralism or fragmented bipolarism and is applicable to...
