This paper presents an experimental study that compares the performance of four selected metaheuristic algorithms for optimizing a time delay system model. Time delay system models are complex and challenging to optimize due to their inherent characteristics, such as non-linearity, multi-modality, and constraints. The study includes an explanation of the choice and core functionality of the selected algorithms, which are both baseline and state-of-the-art variants of self-organizing migrating algorithm (SOMA), state-of-the-art variant from the Success-History-based Adaptive Differential Evolution family of algorithms, with emphasis on diverse search (DISH algorithm), and Covariance Matrix Adaptation Evolution Strategy (CMA-ES) algorithm. The hyperparameters of the metaheuristic algorithms were set using the iRace automatic algorithm configuration framework. The paper emphasizes the importance of metaheuristic algorithms in control engineering for time-delay systems to develop more effective and efficient control strategies and precise model identifications. The experimental results highlight the effectiveness of the state-of-the-art algorithms with specific adaptive mechanisms like population organization process, diverse search and adaptation mechanisms ensuring a gradual transition from exploration to exploitation. Overall, this study contributes to understanding the challenges and advantages of using metaheuristic algorithms in control engineering for time delay systems. The results provide valuable insights into the performance of modern metaheuristic algorithms and can help guide the selection of appropriate adaptive mechanisms of metaheuristics.

Magic as a science of imagination in the work of Ioan P. Culianu (1950–1991)
(Wydawnictwa AGH, 2017) Moretti, Roberta
The powerful spreading of new technologies and the mass media civilization have had a subtle, stealthy effect on the human imagination, a process that has its counterpart in external reality, in historical changes and in society. The role of imagination through historical changes was extensively explored by Ioan P. Culianu, a Romanian historian of religions and specialist in Late Antiquity and gnosticism, whose research was brutally interrupted by his assassination on May 21, 1991. He was shot to death around midday inside of a toilet at the Department of the Divinity School of the University of Chicago where he was teaching. He was only 41 years old. One of his main books is Eros and magic in the Renaissance (The University of Chicago Press, 1987), which has been translated into many languages and is probably one of the most complex and interesting 20$^{th}$-century studies on magic. He points out that the working of fantasy was fundamental to comprehend magical processes in the Renaissance, since magic was primarily directed to affect human imagination through the manipulation of phantams (»images« in Greek). He has been also a pioneer in the study of the historical vicissitudes that caused imagination to change from a civilization based on magic, as in the Renaissance, to a modern one based on science. To the scholar, the transition from a magic-based society to a modern one is explicable primarily by a change in the imaginary. One of the purposes of this paper is to shed light on the work of Ioan P. Culianu, especially on his research on magic, which he carried out throughout his life. Particularly interesting are the articles published in the last period of his life (1990–1991), when he was trying to develop a new paradigm of knowledge in the Humanities, concentrating on the study of the mind. He was shaping an original but uncompleted theory where the »cognitive revolution« was to be applied across and beyond the contexts of human science.

Pomiędzy esencjalizmem a konstruktywizmem. Płeć (kulturowa) w refleksji teoretycznej socjologii - przegląd koncepcji
(Wydawnictwa AGH, 2012) Leszczyńska, Katarzyna; Dziuban, Agata
In this paper the authors take up the attempt to identify the main theoretical tracks of gender categories, which were initially present in the classical sociology, and then in the singled out specialized contemporary sociological subdisciplines. In the paper the transformations within the sociological conceptualization of gender arc presented as the peculiar de-essentialisation. The expression of dc-csscntialising of gender can be noticed in the gradual departing from its biological and naturalistic understanding, which is grounded in the classical reflection of sociology, towards the defining gender in the social and cultural categories (gender roles, power relations, interactions) and finally towards general dcconstmction of the all essential concepts of sexual and gender identities.

Pułapka czy dobrodziejstwo immersyjności w bieganiu długodystansowym? Czas wolny aktywnie wypełniany
(Wydawnictwa AGH, 2023) Prüfer, Paweł Edward
The article describes, explains and interprets the phenomenon of long-distance running through the prism of the immersion category. This concept is rather absent in social sciences, including sociology, therefore an attempt to define it, was made. A search of materials dedicated to the phenomenon of running, posted mainly on Italian and Polish websites was used in this analysis. The method of describing the interpretation of the discourses and content contained in the mottos dedicated to running was applied. First of all, the theory of relationality and the thesis about placing the individual in the space of two social mechanisms: determinism and individual abilities were taken into account. The problem was developed and updated both in its specific cases (narratives and experiences of runners, the author’s personal experience with the phenomenon of running, lofty and distanced opinions about running) as well as in an universal scope (descriptions and interpretations present in various studies dedicated to long-distance running). Based on the carried out analyses, it was concluded in the case of runners, that the phenomenon of running is both liberating, reconstructing their biographies, and immersive, i.e. absorbing, »captivating«.
