Personality, Technology Belief Contexts and Acceptance: Framework and Empirical Testing

This paper describes a new framework for technology acceptance research. Next to an information-system specific belief context, an individual’s personality context and an overall technology-related context are introduced. It is primarily introduced to explore antecedents of technology acceptance’s independent constructs. The framework is proposed so that each of its tiers can host a model best describing the population under examination. The three tiered framework is then operationalized whereby personality is measured through the Five Factor Model, overall technology beliefs are reflected by the Technology Readiness Index and information system –specific beliefs are covered by the Unified Theory of Acceptance and Use of Technology. This research model is tested in a large university hospital setting, where the technology under scrutiny is an Electronic Patient Record

Assessing hospital physicians' acceptance of clinical information systems : a review of the relevant literature

In view, of the tremendous potential benefits of clinical information systems (CIS) for the quality of patient care; it is hard to understand why not every CIS is embraced by its targeted users, the physicians. The aim of this study is to propose a framework for assessing hospital physicians' CIS-acceptance that can serve as a guidance for future research into this area. Hereto, a review of the relevant literature was performed in the ISI Web-of-Science database. Eleven studies were withheld from an initial dataset of 797 articles. Results show that just as in business settings, there are four core groups of variables that influence physicians' acceptance of a CIS: its usefulness and ease of use social norms, and factors in the working environment that facilitate use of the CIS (such as providing computers/workstations, compatibility between the new and existing system...). We also identified some additional variables as predictors of CIS-acceptance

Rank-deficient matrices as a computational tool.

Matrix manifolds and the Jordan structure of the bialternate matrix product.

AbstractThe bialternate product of matrices was introduced at the end of the 19th century and recently revived as a computational tool in problems where real matrices with conjugate pairs of pure imaginary eigenvalues are important, i.e., in stability theory and Hopf bifurcation problems. We give a complete description of the Jordan structure of the bialternate product 2A⊙In of an n×n matrix A, thus extending several partial results in the literature. We use these results to obtain regular (local) defining systems for some manifolds of matrices which occur naturally in applications, in particular for manifolds with resonant conjugate pairs of pure imaginary eigenvalues. Such defining systems can be used analytically to obtain local parameterizations of the manifolds or numerically to set up Newton systems with local quadratic convergence. We give references to explicit numerical applications and implementations in software. We expect that the analysis provided in this paper can be used to further improve such implementations
