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...

BACKGROUND The present study aimed at determining if the addition of spaced education to traditional face-to-face lectures increased the time students kept busy with the learning content of a theoretical radiological science course. METHODS The study comprised two groups of 21 third-year dental students. The students were randomly assigned to a "traditional group" and a "spaced education grou...

A quasi experiment compared the effectiveness of discussion question types on exam scores in an online quantitative methods course at an accredited university. Correlation, ANOVA and MANCOVA were utilized to test the hypothesis that questions exploiting industry examples would increase discussion interaction volume and exam scores more than using theoretical problems. Demographic factors (age, ...

BACKGROUND In the developing world, the diagnostic power of nephrologists is heavily limited by financial, technical and human resource constraints. Urine microscopy (UM) is a basic, inexpensive and relatively simple diagnostic tool, which supplies irreplaceable information. Recently, a theoretical and practical course on UM was organized during the 22nd annual meeting of the Nigerian Society o...

Methods A basic six-hour theoretical course on ECMO was taught to a heterogeneous audience formed by 12 medical students, 10 nurses, 4 perfusionists and 4 physicians. Content included the following topics: 1) concept of ECMO; 2) usage scenarios; 3) aspects of the circuit; 4) differences between pulmonary and cardiac ECMO; 5) management of patients on ECMO; 6) aspects of cannulation; 7) complica...

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...
