Parental and Infant Gender Factors in Parent-Infant Interaction: State-Space Dynamic Analysis.
2017
This study aimed to investigate the influence of parental gender on their interaction with their infants, considering, as well, the role of the infant’s gender. The State Space Grid (SSG) method, a graphical tool based on the non-linear dynamic system (NDS) approach was used to analyze the interaction, in Free-Play setting, of 52 infants, aged 6 to 10 months, divided into two groups: half of the infants interacted with their fathers and half with their mothers. There were 50% boys in each group. MANOVA results showed no differential parenting of boys and girls. Additionally, mothers and fathers showed no differences in the Diversity of behavioral dyadic states nor in Predictability. However…
Modelling Dynamic Systems: Examples Involving an Iconic Oriented Environment
2005
We present a modelling environment based on the use of iconic representations consisting of elements, as containers and connected flows, able to describe the relationships between relevant variables of dynamic systems. The procedures involved are aimed to make students aware of the reasoning processes to describe, formalise and explain complex system behaviours. Moreover, we show how these strategies may allow the overcoming of some well-known difficulties involved in pupil understanding of mathematical formalisms, such as derivatives and differential equations and their real meaning. Our reported modelling examples were experimented on during some laboratory sessions of the Pre-Service Sch…

Thermodynamics: Classical Framework
2016
This chapter starts with a summary of the thermodynamic potentials and the relationships between them which are obtained from Legendre transformation. This is followed by an excursion to some important global properties of materials such as specific heat, expansion coefficients and others. The thermodynamic relations provide the basis for a discussion of continuous changes of state which are illustrated by the Joule-Thomson effect and the Van der Waals gas. These are models which are more realistic than the ideal gas. The discussion of Carnot cycles leads to and illustrates the second and third laws of thermodynamics. The chapter closes with a discussion of entropy as a concave function of …
From conceptualization to constructions in Finnish as an L2 : a case study
2017
AbstractThis study traces the individual learning trajectories of an adult beginner L2 Finnish learner in expressing the extralinguistic concept of evaluation from a dynamic usage-based perspective. Our results provide support for the view of learner language as a dynamic system in which patterns wax and wane and in which a change in one component has the potential to affect the whole system. In the early stages of learning there was a strong preference to use lexical verbs first, and then adjectives. The study also shows that variability plays a role. Finally, the study confirms that the learning of L2 constructions is in some cases item based. However, another highly frequent and superfic…
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…
