    Opis:
    The article examines the role of power in economic theory, with a special focus on the microeconomic theories of the firm. The aim of the paper is twofold. First, the author provides a comprehensive explanation of the concept of power in an enterprise. Second, he attempts to prove that microeconomic theories of the firm may benefit considerably from the theory of power and its findings. The author develops an expanded definition of power based on Dahl’s concept. Two key theoretical approaches to power are presented: managerial and critical. The role of power in neoclassical, behavioral, managerial, institutional, new-institutional and micro-micro theories is examined. The author checks if the findings of the theory of power can be incorporated into microeconomic theories. The analysis reveals that the concept of power is not fully utilized and sometimes even neglected by microeconomic theory. This is despite the fact that the theory of power can enrich the microeconomic view and understanding of the enterprise, Miroński says. He looks at power as a neutral (not necessarily negative), dynamic and complex concept that can help explain many important microeconomic issues. Behavioral and managerial theories propose many alternative goals of the enterprise, and the concept of power may help predict which of these goals would dominate in a given situation. Transaction costs or “ineffectiveness X” from Leibenstein’s micro-micro theory are influenced by power relations within the company. Further research into the application of the theory of power in economic theory seems to be both justified and promising, Miroński concludes.

    Opis:
    This paper sets out to test the possibilities of the Positioning Theory as a means to approach small group phenomena from a micro-cultural perspective. The study draws on a transcription of a videotaped inter-professional team meeting in the field of social services. Analysis of the data was set to examine how the basic concepts of the Positioning Theory suit the analysis of in-group phenomena, what different forms of positioning are present, and how the positioning is connected to the group processes. Studying the group’s interaction shows how it is possible to approach the interaction via the basic concepts of the Positioning Theory and how the positioning is intervened with group processes, such as decision-making, arguing, and conflict. The study also offers a new theoretical and empirical perspective to the research on small group dynamics.

    management theory.
    Opis:
    Aim: There exists an inequilibrium between the available quantity of goods and the level of consumption resulting in local economic polarisations and asymmetric capital concentrations. Replacements of real money with derivative instruments cause strong perturbations on capital markets. Consumer preferences change towards the maximization of the utility of the used capital. The above observations are a basis for the hypothesis that managers, in general, prefer to maximize the momentum profit regardless of the risk of losing the stability of macroeconomic systems. Design/Research method: It is heuristic about the objective function of an organization based on observations, that there are two excluding tendencies in formulating goals: to maximize the profit (using all possible opportunities) and simultaneously to achieve stability in the long run (keeping the micro-macro balance). Conclusions/findings: Managements cause deviations from the micro-macro balance, and at the same time trying to keep this balance. This leads to the following paradox of management (the balance dilemma of management): Managers always try to maximize opportune profits, regardless of future benefits that may be derived from keeping the equilibrium. And conversely, rational long-term stability suggests postponing most opportunities and keeping external boundaries (e.g. realizing sustainable development). However, managers’ temporary preferences lead to an increasing number of unbalanced interactions between organizations and their surroundings, up to the critical point when some catastrophic economic processes may take place. Originality/value of the article: Original heuristics based on the observations of some micro-macro economic balance relations in business practice. Implications of the research: One more paradox in the theory of management have been presented. It is important for base statements of the theory of organizational bahaviors consistency and inferring would be more accurate. JEL: L2, M21, D5, F41

    Opis:
    A domain-boundary element method, based on modified couple stress theory, is developed for transient dynamic analysis of functionally graded micro-beams. Incorporating static fundamental solutions as weight functions in weighted residual expressions, governing partial differential equations of motion are converted to a set of coupled integral equations. A system of ordinary differential equations in time is obtained by domain discretization and solved using the Houbolt time marching scheme. Developed procedures are verified through comparisons to the results available in the literature for micro- and macro-scale beams. Numerical results illustrate elastodynamic responses of graded micro-beams subjected to various loading types. It is shown that metal-rich micro-beams and those with a smaller length scale parameter ratio undergo higher displacements and are subjected to larger normal stresses.

    Opis:
    The following contribution is based on the qualitative data of a seven-country comparative study on the situation of ‘non-traditional students’ at European universities. It focuses on two key findings of an extensive analysis: (1) deeper theoretical insights that emerge from the wealth of data and that are condensed into Axel Honneth’s ‘theory of recognition’; (2) a revealing comparison of the ‘university cultures’ of the seven countries studied. A brief conclusion for future university policies in Europe closes the contribution.

    Opis:
    Since the 1960s, all studies have assumed that a film thickness “h” provides a unique pressure field “p” by resolving the Reynolds equation. However, it is relevant to investigate the film thickness unicity under a given hydrodynamic pressure within the inverse theory. This paper presents a new approach to deduce from an initial film thickness a widespread number of thicknesses providing the same hydrodynamic pressure under a specific condition of gradient pressure. For this purpose, three steps were presented: 1) computing the hydrodynamic pressure from an initial film thickness by resolving the Reynolds equation with Gümbel’s cavitation model, 2) using a new algorithm to generate a second film thickness, 3) comparing and validating the hydrodynamic pressure produced by both thicknesses with the modified Reynolds equation. Throughout three surface finishes: the macro-shaped, micro-textured, and rough surfaces, it has been demonstrated that under a specific hydrodynamic pressure gradient, several film thicknesses could generate the same pressure field with a slight difference by considering cavitation. Besides, this paper confirms also that with different ratios of the averaged film thickness to the root mean square (RMS) similar hydrodynamic pressure could be generated, thereby the deficiency of this ratio to define the lubrication regime as commonly known from Patir and Cheng theory.

    Opis:
    Self-healing grids are one of the most developing concepts applied in electrical engineering. Each restoration strategy requires advanced algorithms responsible for the creation of local power systems. Multi-agent automation solutions dedicated for smart grids are mostly based on Prim’s algorithm. Graph theory in that field also leaves many problems unsolved. This paper is focused on a variation of Prim’s algorithm utility for a multi-sourced power system topology. The logic described in the paper is a novel concept combined with a proposal of a multi-parametrized weight calculation formula representing transmission features of energy delivered to loads present in a considered grid. The weight is expressed as the combination of three elements: real power, reactive power, and real power losses. The proposal of a novel algorithm was verified in a simulation model of a power system. The new restoration logic was compared with the proposal of the strategy presented in other recently published articles. The novel concept of restoration strategy dedicated to multi-sourced power systems was verified positively by simulations. The proposed solution proved its usefulness and applicability.
