Assessing Transfer Entropy in cardiovascular and respiratory time series: A VARFI approach

2021

In the study of complex biomedical systems represented by multivariate stochastic processes, such as the cardiovascular and respiratory systems, an issue of great relevance is the description of the system dynamics spanning multiple temporal scales. Recently, the quantification of multiscale complexity based on linear parametric models, incorporating autoregressive coefficients and fractional integration, encompassing short term dynamics and long-range correlations, was extended to multivariate time series. Within this Vector AutoRegressive Fractionally Integrated (VARFI) framework formalized for Gaussian processes, in this work we propose to estimate the Transfer Entropy, or equivalently G…

Non-linear systems under parametric alpha-stable LÉVY WHITE NOISES

2005

In this study stochastic analysis of nonlinear dynamical systems under a-stable, multiplicative white noise has been performed. Analysis has been conducted by means of the Ito rule extended to the case of α-stable noises. In this context the order of increments of Levy process has been evaluated and differential equations ruling the evolutions of statistical moments of either parametrically and external dynamical systems have been obtained. The extended Ito rule has also been used to yield the differential equation ruling the evolution of the characteristic function for parametrically excited dynamical systems. The Fourier transform of the characteristic function, namely the probability den…

The Quest for Underpinning Theory of Enterprise Architecture - General Systems Theory

2017

Enterprise architecture originates from the 1980’s. It emerged among ICT practitioners to solve complex problems related to information systems. Currently EA is also utilised to solve business problems, although the focus is still in ICT and its alignment with business. EA can be defined as a description of the current and future states of the enterprise, and as a change between these states to meet stakeholder’s goals. Despite its popularity and 30 years of age, the literature review conducted on top information and management science journals revealed that EA is still lacking the sound theoretical foundation. In this conceptual paper, we propose General Systems Theory (GST) for underpinni…

Creating the Socio-technical Context Needed to Derive Benefits from Big Data Initiatives in Healthcare

2021

The application of big data in healthcare typifies a complex socio-technical sys- tem. However, although research and practice have advanced the technical aspects of big data, comparable advancements in the social aspects (i.e., human and structural aspects) are lagging. Literature, especially on socio-technical theory, suggests that organizations may only derive benefits from big data initiatives when technical initiatives are adequate- ly complemented by social interventions. Thus, seeing that big data is receiving consider- able attention in healthcare, researchers have called for further research into the social aspects of the application of big data in healthcare. Adopting a socio-tech…

Developing a metatheoretical framework for second language development : a cultural-historical theory and dynamic systems theory perspective

2017

The main aim of this article-based dissertation is to construct and articulate a dialectical metatheoretical architecture for the study of second language development termed Purposive-Historical Systems Theory (PHiST) invoking, inter alia, the axiomatic imperatives of dynamic systems theory (DST), Vygotskian cultural-historical theory (CHT), and Pepperian root metaphor theory (RMT). Specifically, it primarily purports, first, to demonstrate the tenability of a dialectical synthesis of DST and CHT; second, to philosophize on the fundamental contours of PHiST; third, to apply a novel metatheoretical perspective, as a quintessential example, to reconceptualizing the seminal construct of the Zo…

Dancing with Alternative Lyrics : Integrating Sociocultural, Dialogical, Distributed and Dynamical Conceptualization of Language and its Development …

2016

This paper sets out to chart underlying assumptions and fundamental axioms of an integrative research edifice for studying language and how it is developed over time as a human- and culture-centered and multifaceted phenomenon. Specifically, invoking Vygotskian sociocultural theory, the Bakhtin circle dialogism, distributed language and cognition and dynamic systems theory, it is argued that language is a purposive, multifaceted, complex, dialogical, and dynamic system that emerges distributively across the interpenetrated web of human somatic and brain activities, socio-cultural umwelt, sociohistorically-fashioned artifacts and realized affordances simultaneously and over time. Suggestions…

The dynamics of foreign versus second language development in Finnish writing

2014

Deze studie vanuit een dynamisch perspectief onderzoekt de ontwikkeling van acht beginnende leerders Fins als vreemde (VT; Nederland; focus: grammatica) en tweede (T2; Finland; focus: communicatie) taal. De studie onderzoekt variabelen die syntactische en morfologische complexiteit en accuraatheid uitdrukken in geschreven data en bekijkt verschillen in uitkomsten tussen de groepen en verschillen in ontwikkelingspatronen en interacties door de tijd (9 maanden) tussen variabelen (één hoofdpersoon per groep). De groepstudie toont overeenkomsten in syntactische en morfologische complexiteit door de tijd heen maar verschillen in het gebruik van naamvallen en van enkele daaraan gerelateerde varia…

Systems Approaches in the Enterprise Architecture Field of Research: A Systematic Literature Review

2018

This study explores the use of the systems approaches (systems thinking and systems theories) as the theoretical underpinnings for Enterprise Architecture (EA) research. Both the academic and the practitioner communities have maintained an interest in EA due to its potential benefits, promising for the recent technological and business advances. EA as a research area is, however, characterized by diversified views depicted in different definitions of the concept, and no acknowledged common theoretical foundation. A number of prior studies have noticed this gap in the EA field of research, and called for a strengthening of the theory of EA. Variegated systems approaches have been suggested a…
