Case study method of didactic situations is a modern procedure of effective development of professional abilities in future teachers. I have been using the method for many years in future teachers training in the field of preparation of subject methodologies. A case study does not develop only the subject and didactic competences of future teachers. The self-evaluation and self-reflection proce...

Complex computational systems – such as pervasive, adaptive, and self-organising ones – typically rely on simple yet expressive coordination mechanisms: this is why coordination models and languages can be exploited as the sources of the essential abstractions and mechanisms to build such systems. While the features of tuple-based models make them well suited for complex system coordination, th...

This paper presents a multiple perspectives approach that can help to improve the understanding of knowledge flows in changing collaborative environments. It differs from majority of current modelling methods use analytical or reductionist approach. Our approach is adaptive in that it introduces ways to look at change from different perspectives to help identify changes in complex organisation ...

The web continues to grow at a phenomenal rate and the amount of information on the web is overwhelming. Finding the relevant information on the web remains a big challenge. Due to its wide distribution, its openness and high dynamics, the WWW is a complex system, for which we have to imagine mechanisms of content maintaining, filtering and organizing that are able to deal with its evolving dyn...

BACKGROUND Secondary growth by successive cambia is a rare phenomenon in woody plant species. Only few plant species, within different phylogenetic clades, have secondary growth by more than one vascular cambium. Often, these successive cambia are organised concentrically. In the mangrove genus Avicennia however, the successive cambia seem to have a more complex organisation. This study aimed (...

Total and specific activities of alaninaminotransferase (Al-AT) were determined in general tissues, mitochondrial and cytosol fractions of visual, orbital, motor, limbic areas of brain cortex and hypothalamus of three-month old and one-year old rats under 10-20 days and 30 days protein deprivation and under recovery of normal food regime during the same terms. It was found out that Al-AT activi...

A s a psychologist, my research focuses on the behavior of individual organisms. Such research often requires the integration of causes at multiple levels of organization to explain, predict, and control behavior (e.g., lower levels include genetic, physiological, hormonal, and neurological causes; upper levels include, group, social, and ecological causes of behavior). A question of fundamenta...

In today’s hyper-competitive business environ1 ments virtual organisations are becoming highly dynamic 2 and unpredictable. Individuals may want to work together 3 across organisation boundaries but do not have much prior 4 knowledge about potential partners. The semantic web and 5 its associated new standards appear very promising as can6 didates to support a new generation of virtual organisa...

Issues of sustainability involve the dynamics and interactions of multiple complex adaptive systems at a variety of scales: climatic; ecological; economic; technological; political and social. Some of the most pressing challenges for society are inherently concerned with gaining a better ability to understand and manage the interacting systems upon which we rely. While there is widespread ackno...
