We dwell on how a definition of a theoretical concept of an operating system, suitable to be incorporated in a mathematical theory of operating systems, could look like. This is considered a valuable preparation for the development of a mathematical theory of operating systems .

Island coalescence during Volmer–Weber thin film growth is generally accepted to be a source of tensile stress. However, the stochastic nature of unpatterned film nucleation and growth prevents meaningful comparison of stress measurements taken during growth to that predicted by theoretical models. We have overcome this by systematically controlling island geometry using selective growth of Ni ...

The purpose of the article is to analyze upgrading by looking at the design of fashion garments. To that end, I use the theoretical concept of contextual knowledge to understand the problems faced by firms, and their staff, that want to upgrade through design. Contextual knowledge combines a general knowledge of fashion with the lifeworld that actors use for interpretation of fashion. Lifeworld...

The paper presents the concept of embeddedness of economic activity in relation to agriculture. In this perspective, economic activity can be considered dependent on cognitive structures, structures of social relations, culture, and political institutions. It has been concluded that the idea of embeddedness can be an interesting and useful analytical tool for the analysis of economic activity u...

Using theoretical models, we undertake the first investigation into the synergy and rich phase behavior that emerges when binary particle mixtures are blended with microphase-separating copolymers. We isolate an example of spontaneous hierarchical self-assembly in such hybrid materials, where the system exhibits both nanoscopic ordering of the particles and macroscopic phase transformation in t...

When modelling an employee competency, several facets of this theoretical construct could be identified. One of them is grounded in the employee’s attitudes to work and organization, namely in her/his job involvement, organizational commitment, responsibility etc. The paper deals with results of a survey comparing work and organizational attitudes of four groups of subjects. The groups differed...

The main purpose of the present study is to help managers cope with the negative effects of technostress on employee use of ICT. Drawing on transaction theory of stress (Cooper, Dewe, & O’Driscoll, 2001) and information systems (IS) continuance theory (Bhattacherjee, 2001) we investigate the effects of technostress on employee intentions to extend the use of ICT at work. Our results show that f...

In this paper, we discuss the current state of organic and molecular-scale electronics, some experimental methods used to characterize charge transport through molecular junctions and some theoretical models (superexchange and barrier tunnelling models) used to explain experimental results. Junctions incorporating self-assembled monolayers of organic molecules - and, in particular, junctions wi...

thinking simultaneously of humor and battlefield is hardly expectable; however, the most genuine jokes can be seen in this very battlefield verbal culture in a simple and sensitive form which has rarely been paid attention to. this witticism can be categorized into four classes; namely, devotional, fight and martyrdom, drinking and eating, and social interactions which have the most similitude ...

Given a coalgebra p for HG, an algebra s for GH and the obvious notion of morphism from coalgebra to algebra, we observe that morphisms from Gp to s correspond to morphisms from p to Hs in the manner of an adjunction even when there is no adjunction between G and H. This appears to be one of the basic phenomena underlying the transport of special algebras. A proof of Freyd’s Iterated Square The...
