We suggest the use of a universality-breaking observable based on lepton asymmetries as derived from the left-right asymmetry and the τ polarization at the Z peak, which can efficiently constrain the parameter space of unified theories. The new observable is complementary to the leptonic partial width differences and it depends critically on the chirality of a possible non-universal Z-boson cou...

Connectionist and dynamic systems approaches to development are similar in that they are both emergentist theories that take a very different perspective from more traditional symbolic systems. Moreover, they are both based on similar mathematical principles. Nevertheless, connectionism and dynamic systems differ in the approach they take to the study of development. We argue that differences b...

This paper discusses how an interpretive theory of action was explored and developed through iterative cycles of grounded theory generation. We establish our motivation for employing the grounded theory method in an area that is overflowing with theories of learning, then move on to the practicalities of generating an interpretive grounded theory by following the "vapor trails" left by online l...

This paper presents some aspects of our studies of the conceptual and implementation relationships between Object-Based Concurrent Programming (OBCP) and Distributed Arti cial Intelligence (DAI). The basic argument of this paper is that to implement DAI systems we should nd complementary relations between the theory of social organization chosen for DAI problem-solving and the theory of modelin...

Theories of cognition that posit complementary dual-route processes afford better fits to the data when each route explains a part of the data not explained by the other route. However, such theories must also explain why each route is invoked, lest one can fit any data set with enough routes. One possible explanation is that route selection is based on a least-cost principle: the route that re...

We discuss questions arising from the recent work of Schellekens[17], and also from an earlier paper by Schellekens and Yankielowicz[19]. We summarise Schellekens' results, and proceed to discuss the uniqueness of the c = 24 self-dual conformal field theory with no weight one states, i.e. the Monster module V ♮ [8]. After introducing the concept of complementary representations, we examine Z 2-...

This article makes use of the system dynamics to argue that a number of theories about the performance of territories, developed in the past 20 years, are more complementary than alternative; to demonstrate this, a model of local economy coherent with these schools is designed and simulated. According to these theories, the ability to produce and use knowledge is at the centre of regional compe...

There is an obvious tension between symbolic and subsymbolic theories, because both show complementary strengths and weaknesses in corresponding applications and underlying methodologies. The resulting gap in the foundations and the applicability of these approaches is theoretically unsatisfactory and practically undesirable. We sketch a theory that bridges this gap between symbolic and subsymb...

This paper investigates how firms choose among acquisitions, alliances, and divestitures when they decide to expand or contract their boundaries. The dataset covers 9276 deals announced and completed by 86 members of the Fortune 100 between 1990 and 2000. Our findings support explanations based on resources, transaction costs, internalization, organizational learning, social embeddedness, asymm...

E-government research deals with ‘wicked’ problems that require multidisciplinary approaches to gain a full understanding. One of the main challenges of e-government is to induce change in the structure of public organizations to realize its full potential. This paper investigates e-government induced change using two complementary theoretical lenses applied to an egovernment case study. We use...
