Little is known about how people, contexts, and tools impact decisions to use a Knowledge Management System (KMS). The purpose of this study was to better understand information retrieval when solving difficult problems. Key research questions focused on social structure, interpersonal relationships, and nature of the KMS. In this sequential exploratory study, semi-structured interviews were co...

We study the 4-point function in the Keldysh formalism of the closed time path formulation of real time finite temperature field theory. We derive the KMS conditions for these functions and discuss the number of 4-point functions that are independent. We define a set of ‘physical’ functions which are linear combinations of the usual Keldysh functions. We show that these functions satisfy simple...

We show a relation of the KMS state of a certain C∗Algebra U with the Gibbs state of Thermodynamic Formalism. More precisely, we consider here the shift T : X → X acting on the Bernoulli space X = {1, 2, ..., k} and μ a Gibbs state defined by a Holder continuous potential p : X → R, and L(μ) the associated Hilbert space. Consider the C∗-Algebra U = U(μ), which is a sub-C∗-Algebra of the C∗-Alge...

To any periodic and full C∗–dynamical system (A, α,R), an invertible operator s acting on the Banach space of trace functionals of the fixed point algebra is canonically associated. KMS states correspond to positive eigenvectors of s. A Perron–Frobenius type theorem asserts the existence of KMS states at inverse temperatures equal the logarithms of the inner and outer spectral radii of s (extre...

Knowledge is increasingly being viewed as a critical component for organizations. It is largely people-based and the characteristics of groups of individuals, in the form of organizational cultures, may play a key role in the factors that lead to either the acceptance or rejection of knowledge management systems (KMS). The primary objective of this research is to explore how dimensions of organ...

We study relations between (H,β)–KMS states on Cuntz–Krieger algebras and the dual of the Perron–Frobenius operator L∗ −βH . Generalising the well– studied purely hyperbolic situation, we obtain under mild conditions that for an expansive dynamical system there is a one–one correspondence between (H,β)– KMS states and eigenmeasures of L∗ −βH for the eigenvalue 1. We then consider representation...

It is shown that for any KMS-state of a classical system of noncoincident particles, the distribution functions are absolutely continuous with respect to Lebesgue measure; the equivalence between KMS states and Canonical Gibbs States is then established.

User acceptance is one of the key fundamentals for the development of knowledge management systems (KMS). We propose a model of the factors that influence the contribution to KMS repositories in organizations. We use both qualitative and quantitative methodologies to validate a revised unified theory of acceptance and use of technology (UTAUT). We describe a theoretical framework that incorpora...

Knowledge artifacts are units retained in repository-based knowledge management systems (KMS). When adopting cases as the representation for knowledge artifacts in KMS, one of the benefits is the automated construction of reports.
