Introduction. The work is devoted to the formation of new conceptual criteria for the effectiveness of international cooperation in the context of the geo-economic space digital transformations. The introduction spells out the general content of the modern geo-economic space and stipulates the need for a conceptually new approach to determining the effectiveness of interaction in this space. Theoretical analysis reveals the methodology for studying synergetic efficiency, substantiates the parameters of synergistic efficiency. Empirical analysis. The real events of the modern geo-economic space, which set the vector of synergetic efficiency of international interaction, are analyzed. Results. The content of a new geo-economic space in the context of digital transformations is disclosed. The features of international cooperation are revealed, which, due to the blurring of national borders, goes into the supranational level of interaction. The irrelevance of classical and traditional approaches to substantiating the effectiveness of cooperation in new conditions is shown, which necessitates the development of conceptually new criteria.

The paper is devoted to the problem of fault identification in technical systems described by non-stationary nonlinear dynamic equations under unmatched disturbances. To solve the problem, sliding mode observers are used. The suggested ap- proach is based on the model of the original system of minimal dimension having different sensitivity to the faults and distur- bances in contrast to the traditional approaches to sliding observer design which are based on the original system. Additionally it is assumed that matrices describing such a model have the canonical form and are constant. The main purpose of using such a model is possibility to take into account the non-stationary feature of the systems. As a result, the model has stationary dynamic and non-stationary additional term that allows to promote sliding mode design. Besides, the new approach to design sliding mode observers is suggested. The peculiarity of this approach is that it does not require that original systems should be minimum phase and detectable. According to the traditional approaches stability of the observer is provided by minimum phase and detectability properties. In our approach, stability of the observer is achieved due to the canonical form of the matrices describing the model. In addition, the matching condition is not necessary. This allows to extend a class of systems for which sliding mode observers can be designed. Theoretical results are illustrated by practical example of electric servoactuator.

Different Levels

ABSTRACTA classification is proposed, based mainly on major element analytical data plotted in a coherent set of three simple chemical-mineralogical diagrams. The procedure follows two complementary steps at two different levels. The first is concerned with the individual sample: the sample is given a name (e.g. granite, adamellite, granodiorite) and its chemical and mineralogical characteristics are determined. The second one is more important: it aims at defining the type of magmatic association (or series) to which the studied sample or group of samples belongs. Three main types of association are distinguished: cafemic (from source-material mainly or completely mantle-derived), aluminous (mainly or completely derived by anatexis of continental crust), and alumino-cafemic (intermediate between the other two types). Subtypes are then distinguished among the cafemic and alumino-cafemic associations: calc-alkaline (or granodioritic), subalkaline (or monzonitic), alkaline (and peralkaline), tholeiitic (or gabbroic-trondhjemitic), etc. In the same way, numerous subtypes and variants are also distinguished among the aluminous associations using a set of complementary criteria such as quartz content, colour index, alkali ratio, quartz–alkalies relationships and alumina index.Although involving a new approach using partly new criteria, this classification is consistent with most of the divisions used in previous typologies. The method may also be used in the classification of the volcanic equivalents of common plutonic rocks.

The levels of conflictological culture of pedagogues and engineers, the peculiarities of its formation as well as the comparison of the conflictological culture’s levels among representatives of these specialties on the base of their gender and work experience are analyzed in the proposed research. Each specialist owns a certain level of the conflictological culture’s development and he/she expresses it in a professional environment. The relevance of the research’s theme is caused by the necessity to improve conflictological culture of specialists for their further successful activities. The Aim of the research is the identification of differences in the levels’ formation of specialists’ conflictological culture by the example of pedagogues and engineers and the influence of such a characteristic as a gender and work experience  on it. The Object of the research is the process of forming conflictological culture of pedagogues and engineers.

<p class="apa">This paper examines Nigeria's democratization dilemmas and the imperatives of an educational framework against the backdrop of the Boko Haram insurgency. It identifies and connects the pattern, character and dynamics of the existing educational system. It also discusses the system’s failure in calling for a new approach to overcome the prevailing dearth of civic order and the increasing spread of dissent groups. This new method is about acculturating Nigerian youth into a more civic culture, a Nigeria where citizens can live side by side with each other in peace.” While examining both theoretical and practical characteristics of this new educational agenda, the paper especially examines the link between philosophical education and the development of a civic culture, trusting that such a connection suggests an approach to education that may assist future policy makers, educators, and teachers. Specific theoretical analysis of pedagogical and philosophical education contained here can further the current understanding of how philosophical education is likely to facilitate the development of the values, beliefs, and attitudes that generally underpin the operations of a civic society, developments desperately needed to address the problem of Boko Haram and the increasing spread of dissent groups in Nigeria.</p>

Competency Management

This chapter introduces a new approach in organizational Competency Management which is based on Korossy’s competence performance approach and which rests on the central idea of connecting competencies to actual job performance. Such an approach has several important benefits when compared to more traditional approaches. First, it brings competency modeling and assessment more closely to the actual work processes and tasks. Secondly, it makes possible validation of the models and the assessment within the modeling and assessment procedure. Finally, it is better able to cope with more dynamic and knowledge based settings. Three case studies in Engineering, Human Resource Management and Research and Development illustrate how the approach is introduced, evaluated and applied. The purpose of the chapter is to inform researchers in eLearning and Knowledge Management of how competencies can be used to support work integrated assessment and learning.

In the wake of the Cold War, democracy has gained the status of a mantra. Yet there is no consensus about how to conceptualize and measure regimes such that meaningful comparisons can be made through time and across countries. In this prescriptive article, we argue for a new approach to conceptualization and measurement. We first review some of the weaknesses among traditional approaches. We then lay out our approach, which may be characterized ashistorical,multidimensional,disaggregated,andtransparent.We end by reviewing some of the payoffs such an approach might bring to the study of democracy.

Extracellular Potentials

In electrophysiology studies, it is becoming increasingly common to explain experimental observations using both descriptive methods and quantitative approaches. However, some electrophysiological phenomena, such as the generation of extracellular potentials that results from the propagation of the excitation source along the muscle fiber, are difficult to describe and conceptualize. In addition, most traditional approaches aimed at describing extracellular potentials consist of complex mathematical machinery that gives no chance for physical interpretation. The aim of the present study is to present a new method to teach the formation of extracellular potentials around a muscle fiber from both a descriptive and quantitative perspective. The implementation of this method was tested through a written exam and a satisfaction survey. The new method enhanced the ability of students to visualize the generation of bioelectrical potentials. In addition, the new approach improved students' understanding of how changes in the fiber-to-electrode distance and in the shape of the excitation source are translated into changes in the extracellular potential. The survey results show that combining general principles of electrical fields with accurate graphic imagery gives students an intuitive, yet quantitative, feel for electrophysiological signals and enhances their motivation to continue their studies in the biomedical engineering field.
