Although currently pole dancing is growing in popularity due to its sport dimension, it seems that such a form of expression is still commonly associated with strip clubs and connotes above all the erotic performance of a woman in front of a male audience. And yet, as one can find by frequenting dance studios that teach pole dancing, it is practiced not only by women, but also by men and children. Thus keeping in mind the ambiguity that arises at the intersection of competing optics in decoding the pole dance—with regard to “perpetuate interpretation logic” and the everyday experience of people undertaking the activity—the aim of this paper is to reflect on the issue of constructing and interpreting the meanings of actions and processes within the context of pole dancing. These processes can be seen as a reflection of the everyday life in which they occur.

The main thesis of this paper is the assertion that, in contrast to the prevailing opinion about the decline or deep crisis of the intelligentsia, it is precisely this social group—and especially its elite—that is the dominant actor in social life. This thesis emerges from an analysis of the role of the intelligentsia, using ‘longue durée’ categories and also the broader international perspective of ‘world system theory’, in which Poland is assigned to the (semi)-periphery. Elements of Pierre Bourdieu’s theory, particularly the idea of cultural capital and the field of power, are an important theoretical poin in the author’s argument. In this view, the structurally privileged position of the intelligentsia in Poland is understood as an aspect of the specific configuration of the Polish field of power, in which—at least since the end of the First World War—cultural capital turns out to be the strongest and most stable dimension in the creation and reproduction of elite social positions.

The paper recapitulates recently conducted investigations of non-proportional Luenberger observers, applied to reconstruction of state variables of induction motors. Three structures of non-proportional observers are analyzed, a proportional-integral observer, modified integral observer and observer with integrators. Criteria for gain selection of the observer are described, classical ones based on poles, as well as additional, increasing observer’s robustness. Fulfilment of the presented criteria can be ensured with the three proposed methods for gain selection, two analytical, based on dyadic transformation and one based on optimization.

The aim of the article is an attempt to trace the fate of several appellatives grouped in the lexical field around the hyperonym świnia ʽpig, swine’ (wieprz ʽhog’, knur/kiernoz ʽboar’ and prosię ʽpiglet’) as the motivation of many names in Polish onymy, mainly in anthroponymy and toponymy. My research has been conducted along the lines of historical anthropology. Proper names in this approach play an important role in the reconstruction of the past. The field of interest of this article includes mainly names belonging to the old onymic layer. Proper names arise from the lexicon of a given language, which is why my analysis is based on lexical and semantic methodology. My point of departure is the meaning (often reconstructed) of appellative lexical units, including their semantic modifications in the proprial layer. I interpret proper names on the basis of findings regarding their origin and motivation. The first names motivated by the lexeme świnia were associated with the economic organization of the Piast state. In the article I present the history of their creation. I go on to discuss the other lexemes which became the basis of many names belonging to different naming categories. The presence of etymons of interest to us in so many proper names during the Middle Ages allows us to draw the conclusion that pigs played an extremely important role in the lives of our ancestors.

W artykule zdefiniowano lokalną politykę społeczną jako pole instytucjonalne. Obszar rozważań ograniczono do państw demokratycznych o zdecentralizowanym modelu rządów, implementujących zasady wielosektorowej polityki społecznej (welfare pluralism). Przedstawiono wymiary różnicujące pola instytucjonalne, zaczerpnięte z prac badawczych wykorzystujących perspektywę teoretyczną konflacji centralnych. Ponadto zaprezentowano główne korzyści i głosy krytyki związane z używaniem koncepcji pola do opisu mezospołecznych układów interakcyjnych.

The pole phase modulation (PPM) technique is an effective method to extend speed range and torque capabilities for an integrated starter and hybrid electric vehicles applications. In this paper, the five pole-phase combination types of a multiphase induction motor (IM) with 36 stator slots and 36 stator conductors are presented and compared quantitatively by using the time-stepping finite element method (TS-FEM). The 36 stator conductors of the proposed multiphase IM are fed by a 36 leg inverter and the current phase angle and amplitude of each stator conductor can be controlled independently. This paper focuses on the winding connection, the PPM technique and the performance comparative analysis of each pole-phase combination types of the proposed multiphase IM. The flux distribution, air-gap flux density, output torque, core losses and efficiency of five pole-phase combination types have been investigated.

Praca przedstawia historię terminu „eter”: jego wprowadzenia i rozwoju. Omówione zostają różne koncepcje eterowe aż do czasów Einsteina i wyparcia terminu „eter” z naukowej ontologii, a następnie próby przywrócenia tego terminu do nauki. Autorka wyjaśnia, jak mimo zmiany teorii naukowej termin teoretyczny może nie utracić odniesienia przedmiotowego.

A buckling analysis of temperature-dependent embedded plates reinforced by single-walled carbon nanotubes (SWCNTs) subjected to a magnetic field is investigated. The SWCNTs are distributed as uniform (UD) and three types of functionally graded nanotubes (FG), in which the material properties of the nano-composite plate are estimated based on the mixture rule. The surrounding temperature-dependent elastic medium is simulated as Pasternak foundation. Based on the orthotropic Mindlin plate theory, the governing equations are derived using Hamilton's principle. The buckling load of the structure is calculated based on an exact solution by the Navier method. The influences of elastic medium, magnetic field, temperature and distribution type, and volume fractions of SWCNT are shown on the buckling of the plate. Results indicate that CNT distribution close to the top and bottom are more efficient than that distributed near the mid-plane for increasing the stiffness of the plates.

Noise control is essential in an enclosed machine room where the noise level has to comply with the occupational safety and health act. In order to overcome a pure tone noise with a high peak value that is harmful to human hearing, a traditional reactive muffler has been used. However, the traditional method for designing a reactive muffler has proven to be time-consuming and insufficient. In order to efficiently reduce the peak noise level, interest in shape optimization of a Helmholtz muffler is coming to the forefront.

Helmholtz mufflers that deal with a pure tone have been adequately researched. However, the shape optimization of multi-chamber Helmholtz mufflers that deal with a broadband noise hybridized with multiple tones within a constrained space has been mostly ignored. Therefore, this study analyzes the sound transmission loss (STL) and the best optimized design for a hybrid Helmholtz muffler under a space- constrained situation. On the basis of the plane wave theory, the four-pole system matrix used to evaluate the acoustic performance of a multi-tone hybrid Helmholtz muffler is presented. Two numerical cases for eliminating one/two tone noises emitted from a machine room using six kinds of mufflers (muffler A~F) is also introduced. To find the best acoustical performance of a space-constrained muffler, a numerical assessment using a simulated annealing (SA) method is adopted. Before the SA operation can be carried out, the accuracy of the mathematical model has been checked using the experimental data. Eliminating a broadband noise hybridized with a pure tone (130 Hz) in Case I reveals that muffler C composed of a one- chamber Helmholtz Resonator and a one-chamber dissipative element has a noise reduction of 54.9 (dB). Moreover, as indicated in Case II, muffler F, a two-chamber Helmholtz Resonator and a one-chamber dissipative element, has a noise reduction of 69.7 (dB). Obviously, the peak values of the pure tones in Case I and Case II are efficiently reduced after the muffler is added.

Consequently, a successful approach in eliminating a broadband noise hybridized with multiple tones using optimally shaped hybrid Helmholtz mufflers and a simulated annealing method within a constrained space is demonstrated.

One of the key issues in contemporary urban studies is to consider the city from the perspective of culture and consumption, which are treated as new drivers of urban development and economic prosperity, the essence of urban ways of life, and arenas for the implementation of urban policies. In a consumer society, cities become important nodes where collective and individual consumption takes place on a massive scale. The urban system organizes capabilities and provides the resources for consumption, thus facilitating various kinds of lifestyles. As a result, the urban space operates as an arena of competition, where different consumer orientations and social categories strive physically and symbolically to occupy ground, produce meanings, and create belonging in the spaces and places that constitute the city. In applying Pierre Bourdieu’s concept of a “social field,” the aim of the article is to show how the space of social positions corresponds to the space of cultural practices. Drawing on the study of cultural and leisure activities in Wrocław, four general categories of urban residents are revealed and characterized by their distinct positions in different dimensions of the social space. The analysis also points to social capital (social networks) as an efficient new principle of cultural differentiation. The paper closes with the author’s concluding remarks and guidelines for further research.

In the paper an approach to design of multipurpose control systems is considered. It is presented an universal and efficient algorithm for synthesis of multipurpose control system for proper, invertible and right-invertible multi-input multi-output dynamic (MIMO) plants which can be both unstable and/or non-minimumphase. The developed control systems feature both dynamic (either block or row-by-row) decoupling and arbitrary closed-loop pole placement and zero steady-state errors for regulation or tracking processes in presence of (non-diminishing) disturbances.

This article examines the relationship of Maryla Wolska with the poets and artists of the Young Poland in Lwów and, more broadly, with the literary community of the early 20th century. She was a leading light of Płanetnicy (The Rainmakers), an informal group of artists who met at her house in Lwów. The role of a friend and mate, someone who was treated equally as a writer, did not sit well, however, with her role as mistress of the house, hostess of a literary salon and representative of a family which occupied a high position in the social hierarchy. To ride on the crest of the wave she strove to combine two strategies, a modern jauntiness and a studious attention to 19th-century proprieties. Although she did well for herself, her success was by no means complete.

Podejście agregacyjne to obecnie dominujący sposób prowadzenia analiz w badaniach nad działaniami zbiorowymi i ruchami społecznymi. W obrębie metod agregacyjnych działania analizuje się jako sumę wartości odrębnych elementów (zmiennych). Artykuł zawiera praktyczną ilustrację technik uzupełnienia agregacyjnych metod badawczych metodami relacyjnymi w socjologii ruchów społecznych. Autor opisuje wyniki badania, którego przedmiotem był ruch skrajnej prawicy w Polsce, w latach 1990–2013. Po zaobserwowaniu zmian czasowych w wariancji przemocy stosowanej przez ruch skrajnej prawicy, zaistniała potrzeba zastosowania bardziej precyzyjnego narzędzia, które umożliwiłoby wyjaśnienie, dlaczego w określonym przedziale czasowym skala przemocy istotnie zmalała. Regresja logistyczna okazała się tylko częściowo pomocna w ustaleniu warunków, w których przemoc ze strony skrajnej prawicy słabnie. Dopiero relacyjne ujęcie pozwoliło uchwycić najważniejsze cechy „przestrzeni” (pola), w jakiej funkcjonuje ruch skrajnej prawicy w Polsce.

With the Act on the Polish Card Poland followed the pattern of some European states (mostly Central and Eastern European ones) of enacting specific domestic legislation conferring special treatment and benefits to persons who are recognized as its kin-minorities. The most important analysis of this phenomenon from the perspective of international law was the 2001 Venice Commission’s report entitled “Report on the Protection of National Minorities by their Kin-State.” The Polish legislation was adopted in 2007, so for obvious reasons it was not considered by the Venice Commission. However, a rather unexpected and unusual examination of the Polish kin-state legislation from the perspective of international law came from Belarus. The Constitutional Court of the Republic of Belarus (CCRB) conducted a comprehensive examination of the Act on the Polish Card in 2011. The main aim of this article is to present and comment on the reasoning of the CCRB. Beginning with the broader context, this article starts with a presentation of the origins and a short description of the Act on the Polish Card, followed by a discussion of why the Polish Card and other kin-state legislation instruments are topics of concern in international law. The main part of the article is devoted to the presentation and assessment of the 2011 CCRB decision on the Act on the Polish Card. The author’s assessment confirms at least some of the concerns put forward by the CCRB, i.e., that both the Act on the Polish Card and the practice based on it contradict some norms and principles of international law, namely the principle of territorial sovereignty, the norms of consular law, and several bilateral treaties in force between these two states. Bearing in mind that despite those concerns more than a quarter-million Polish Cards (also sometimes called Pole’s Cards) have been issued so far by the Polish authorities, the article ends with a discussion of why such a prolonged nonconformity with international law is possible.

Electromagnetic mill installation for dry grinding represents a complex dynamical system that requires specially designed control system. The paper presents model-based predictive control which locates closed loop poles in arbitrary places. The controller performs as gain scheduling prototype where nonlinear model – artificial recurrent neural network, is parameterized with additional measurements and serves as a basis for local linear approximation. Application of such a concept to control electromagnetic mill load allows for stable performance of the installation and assures fulfilment of the product quality as well as the optimization of the energy consumption.
