Abstract

This work attempts to reconstruct the culture that contributed to the philosophical way of thinking. My goal is to extract two important factors: religion carrying individual experience and the importance of certain ideas which are present in that culture. Sources of philosophical thinking can be found in the structure of polis. Only on its basis could the idea of the wise man and citizen as well as religion-oriented individual experience be raised. Greek polis paves the way for a new style of thinking by creating the conditions for its citizens to follow the ideal, regardless of the position they occupy in society. Sustainability, which should be a feature of a good citizen, is also the essence of society. Highly positioned wisdom as moral reflection tinged with religiosity allows thinking according to the laws of logos. Finally, the experience offered by the mystery cults leads to the transformation of their own existence and the emergence of a way of recognition of reality different than before. Undeniably, all the elements related to structure policies with its ideals contribute to the emergence of a new way of thinking in the form of philosophy. One could say that the philosophical objectivity is preceded by the subjectivity and rationality of its roots dating back to irrationality.

Abstract

We analysed the empirical importance of the capital flows in processes of economic convergence of the CEE region. We depart from reference net measures of capital flow reflecting the level of development of the financial system and focus on gross capital flow. Our econometric model is based on Seemingly Unrelated Regression Equation (SURE) elaborated by Arnold Zellner. This environment seems an alternative to standard panel regression, because it enables cross-country heterogeneity of parameters of interest (like pace of convergence). We tested several restrictions of the unconstrained SURE model, leading to simpler specifications that would allow for regional homogeneity of the role of a particular factor (like capital flows) in growth fluctuations and β-type convergence.

Abstract

The state of development, the existing and emerging forms of development, the intensity and legibility of settlement systems, all this is essential for the living conditions of urban residents, their surroundings and peripheral systems. The purpose of the article is to assess the accessibility to market and public services by estimating the distance to these services from housing facilities in Poland. The use of the residential dispersion ratio (RDR) and an analysis of the spatial distribution of municipalities with the highest values of the coefficient allows to identify areas where accessibility to public and market services is weak.

Abstract

In Nantes, the last shipyard closed in 1986 leaving the city in a desperate situation. The cranes, symbolizing the industrial activity, one by one stopped. Unemployment stroked. The question was between turning the page, tearing down the workshops and reinventing a new story or trying to preserve would appear to most of the population, a kind of modern bulky legacy. In the early 2000’s, the revitalization of Nantes’ former industrial area, led to developing a new way thinking. Instead of designing an urban map with major spots and rows of housing, A. Chemetoff thought better to draw an urban landscape where the past could mix with the future. The industrial heritage has been then preserved in two diff erent ways: construction halls have been reshaped preserving the original structure, everything should be reversed. The intangible heritage, meaning worker’s knowledge, has been reinvested in the cultural industry. This way, the image of the city, its brand, moved from industrial to cultural, attracting a new kind of business, mainly high-tech, students, in a new: “art de Vivre” (Art of living).

Abstract

The topic of the article is a description of European urbonyms which fulfilled both political and commemorative roles in the past. The city names are presented in chronological order starting from ancient times to the 20th century. The ancient toponyms are related to the expansion of the Roman Empire, and the names of Roman emperors are used as a foundation for these toponyms. Such urbonyms created on the outskirts of the Roman Empire made reference to their new political allegiance and confirmed it. These naming practices therefore played an important role in the process of territorial expansion and the consolidation of political control. This naming model was also present in Byzantium, and became popular on the outskirts of medieval Ruthenia under the influence of the Byzantine Empire. The tradition of commemorating political rulers through toponyms stayed constant in the Eastern Slavic regions, and was continued by the Russian monarchy as well as the USSR. Such naming practices were initially used as a tool for the structural organisation of Kievan Rus’, and later to erase foreign names from these regions of Tsarist Russia. In Communist times, this tradition reaffirmed the new political reality through the use of surnames of political figures in toponyms. In the 20th century there was an increase in surnames featured in urbanonyms (the names of streets, squares, housing estates). This increase was meant to preserve the memory of remarkable individuals in society.

Abstract

W kopalniach podziemnych w wyniku wykonywania różnego rodzaju wyrobisk, na osuwiskach ziemi podczas ich aktywnych ruchów a także w czasie trzęsień ziemi dochodzi do zmian pierwotnego pola naprężenia i deformacji górotworu. Górotwór lub materiał skalny poddawany różnego rodzaju obciążeniom ulega deformacji trwałej i jest źródłem różnego rodzaju fal sejsmicznych, emisji sejsmoakustycznej (SA) i elektromagnetycznej (EM). W artykule przedstawiono wyniki badań laboratoryjnych emisji elektromagnetycznej w czasie jednoosiowego ściskania próbek skalnych. Uzyskane wyniki pomiarów emisji EM oraz emisji SA wskazują na ich silny związek ze stopniem obciążenia badanej próbki skalnej. W analizie otrzymanych wyników stwierdzono, że emisja EM dokładniej odzwierciedla stan naprężenia i deformacji w próbce w porównaniu do emisji SA. Można wnioskować, iż opracowanie systemu obserwacyjnego opartego o pomiar emisji EM może być przydatny w wyrobiskach górniczych do oceny zagrożeń związanych z obciążaniem skał. System taki powinien pracować bezinwazyjnie oraz charakteryzować się niskim kosztem i nieskomplikowaną obsługą. Budowa takiego sytemu może wspomagać stosowane powszechnie systemy geofizyczne w kopalniach.

Abstract

The rheological behaviour of cemented paste backfill (CPB) has an important influence on the stability of its transportation in pipelines. In the present study, the time-dependent rheological behaviour of CPB was investigated to elucidate the effects of time and solid content. Experimental results showed that when CPB is subjected to a constant shear rate, the shear stress gradually decreases with time before finally stabilis ing. When the solid content was 60%~62%, a liquid network structure was the main factor that influenced the thixotropy of CPB, and the solid content had less influence. When the solid content was 64%~66%, a floc network structure was the main factor that influenced the thixotropy of CPB, and the solid content had a more significant influence on the thixotropy than the shear rate. The initial structural stability of CPB increased with the solid content, and this relationship can be described by a power function. Based on the experimental results, a calculation model of pipeline resistance considering thixotropy was proposed. The model was validated by using industrial experimental data. The current study can serve as a design reference for CPB pipeline transportation.

Abstract

In this publication, the strategy of land resources administration is presented on the basis of consideration of proposed result factors. The research methodology is based on the use of the PESTLE analytical model in conjunction with economic-mathematical modeling. The scientific novelty of the publication is developing the technology of administration of land resources on the basis of cadastral and other statistical information, which allows obtaining scientifically grounded solutions on the use of land resources. Considering the process of Land Resources Administration as a procedure based on making certain decisions when creating a management system which takes into account the internal and external relationships in this system, the postulate is about determining the degree of trust in this system, establishing economic, environmental and social risks when using it. To a certain extent, the process of Land Resources Administration is a prediction of the effective use of this natural potential in the future. It should be noted that the reliability of the forecast decision depends on the nature and parameters of uncertainties and the duration of their validity. Consequently, while making operational decisions on land resources for a short perspective, the forecasting is more reliable than for a long one. It becomes an effective mechanism of objective evaluation of the state of land resources and the prospects for their use. In this publication the main influencing decision making factors and the technological scheme of the solution of the problem are given.

Abstract

Starting in the early years of education, math anxiety is negatively related to mathematic outcomes, therefore there is a need for its adequate measurement in young children. This study presents the psychometric properties of the modified Abbreviated Math Anxiety Scale for Elementary Children (mAMAS-E) for first- to third-grade children based on mAMAS. The validity of mAMAS-E was determined by a series of tests. The analysis confirmed its two-factor structure (Testing and Learning), positive relationships between mAMAS-E and math, general, and test anxiety, and a negative relationship with mathematical achievement. Children with a high level of math self-esteem and math self-confidence (but not Polish language self-esteem and self-confidence) have lower math anxiety in comparison to those with a moderate level. The results also indicate that girls have a higher level of math anxiety than boys. The validity and internal consistency of mAMAS-E are satisfactory; therefore, mAMAS-E may be a recommendable questionnaire for measuring math anxiety in young children.

Abstract

In this article we focus on optimal control problems involving a nonlinear fractional control system of different orders with Caputo derivatives, associated to a Lagrange cost functional. Based on a lower closure theorem for orientor fields combined with Filippov’s approach, we derive an existence result for at least one optimal solution for such a problem.

Abstract

Each European Union Member State keeps a register of data on properties located in its territory. The number, type and scope of these properties are determined by each Member State’s needs. The INSPIRE Directive enables the scope of data to be harmonised, and the data to be made available for the purpose of assisting legislators in taking decisions and actions likely to have either direct or indirect impact on the environment. The aim of the study was to indicate the basic differences between the data contained in Polish and Latvian cadastres. Unlike other similar studies analysing the content of data in the cadastre, this article pays special attention to the number of available sets of data about the parcel and its surroundings, the ease of access to these data and the possibility for acquiring them by an interested party without incurring additional fees. This is particularly important in activities related to spatial management and the development of an information society. The results show that in both countries, the decision makers have approached the INSPIRE Directive differently. Direct analyses conducted for the cities of Wrocław (Poland) and Riga (Latvia) demonstrated that the information system in Wrocław contains a considerably greater scope of information available free of charge, is easier to use and offers more services. The Latvian Republic’s spatial information system provides a less-developed scope of information about real estate (without fees) that is dispersed on several websites, which slows down and hinders its use.

Abstract

As communication grows ever more media-centric, it often intends to modify the addressee’s attitude. In this context, our chapter aims to investigate a relatively little- examined film review genre from the discursive, pragmatic and rhetorical perspective. The selected corpus consists of one hundred French and Polish journalistic reviews of three famous films from 2019. The act of persuasion we focus on corresponds to a set of strategies exploiting exploiting the deliberative and epideictic dimensions of discourse as well as the rhetorical principles of movere and delectare in order to instil particular views and concepts. Hence, to some extent, the described procedures draw on other discourses, such as elite, advertising, stylistic and filmic discourse. Therefore, our study centres around these new intrinsic features of the film review’s multifaceted nature considered as a sociocultural activity based on the justified assessment and the addresser’s ethos.

Abstract

The aim of this paper is to suggest a framework for research on non-native bilingualism (NNB) in Poland (www.nnbproject.eu). The term non-native bilingualism refers to a situation where, in a Polish family residing in Poland, one or both parents resolve to permanently use a non-native language when communicating with their child or children. The research problems of the “NNB in Poland” project are discussed briefly; the author explains the origins of the term „non-native bilingualism”, defines other terms used in the research, presents the case for and against NNB and collates the common beliefs with the results of contemporary research on bilingualism, including non-native bilingualism.

Abstract

The aim of the study study was to model, with the use of a neural network algorithm, the significance of a variety of factors influencing the development of hearing loss among industry workers. The workers were categorized into three groups, according to the A-weighted equivalent sound pressure level of noise exposure: Group 1 (LAeq < 70 dB), Group 2 (LAeq 70–80 dB), and Group 3 (LAeq > 85 dB). The results obtained for Group 1 indicate that the hearing thresholds at the frequencies of 8 kHz and 1 kHz had the maximum effect on the development of hearing loss. In Group 2, the factors with maximum weight were the hearing threshold at 4 kHz and the worker’s age. In Group 3, maximum weight was found for the factors of hearing threshold at a frequency of 4 kHz and duration of work experience. The article also reports the results of hearing loss modeling on combined data from the three groups. The study shows that neural data mining classification algorithms can be an effective tool for the identification of hearing hazards and greatly help in designing and conducting hearing conservation programs in the industry.

Abstract

Simultaneous propagation of vibrations and noise has an important role in the task of minimizing vibroacoustic hazards on the station of operator of the construction machinery. In many cases vibrations transferred by the construction are processed to noise in different points of the machine. As a result, they may increase the level of noise at the workplace. The paper presents the proposition of a simple estimation of noise and vibration propagation paths of the machine. On the basis of the analysis of hydraulic excavator an effectiveness of a proposed procedure was shown. This procedure helps to minimize the transfer of vibrations of power unit in selected frequency ranges which led to the change of overall noise level in operator’s cab about 5 dB.

Abstract

The purpose of this work is to distinguish between Acoustic Emission (AE) signals coming from mechanical friction and AE signals coming from concrete cracking, recorded during fourteen seismic simulations conducted with the shaking table of the University of Granada on a reinforced concrete slab supported on four steel columns. To this end, a particular criterion is established based on the Root Mean Square of the AE waveforms calculated in two different temporal windows. This criterion includes a parameter calculated by optimizing the correlation between the mechanical energy dissipated by the specimen (calculated by means of measurements with accelerometers and displacement transducers) and the energy obtained from the AE signals recorded by low-frequency piezoelectric sensors located on the specimen. The final goal of this project, initiated four years ago, is to provide a reliable evaluation of the level of damage of Reinforced Concrete specimens by means of AE signals to be used in future Structural Health Monitoring strategies involving RC structures.

Abstract

Globally more than 5.2 billion hectares of farming fields are damaged through erosion, salinity and soil deterioration. Many salt stress tolerant bacteria have plant growth promoting (PGP) characteristics that can be used to overcome environmental stresses. Isolation and screening of salt-tolerant endophytes from Salicornia brachiata were achieved through surface sterilization of leaves followed by cultivation on 4% NaCl amended media. Performance of isolates towards indole-3-acetic acid (IAA) production, phosphate solubilization, ACC deaminase activity, ammonia production, siderophore production and stress tolerance were determined. On the basis of the highest plant growth promoting activity, SbCT4 and SbCT7 isolates were tested for plant growth promotion with wheat and maize crops. In the present study, a total of 12 morphologically distinct salt-tolerant endophytic bacteria was cultured. Out of 12 isolates, 42% of salt-tolerant endophytes showed phosphate solubilization, 67% IAA production, 33% ACC-deaminase activity, 92% siderophore production, 41.6% ammonia production and 66% HCN production. A dendrogram, generated on the basis of stress tolerance, showed two clusters, each including five isolates. The bacterial isolates SbCT4 and SbCT7 showed the highest stress tolerance, and stood separately as an independent branch. Bacterial isolates increased wheat shoot and root dry weights by 60–82% and 50–100%, respectively. Similarly, improved results were obtained with maize shoot (27–150%) and root (80–126%) dry weights. For the first time from this plant the bacterial isolates were identified as Paenibacillus polymyxa SbCT4 and Bacillus subtilis SbCT7 based on phenotypic features and 16S rRNA gene sequencing. Paenibacillus polymyxa SbCT4 and B. subtilis SbCT7 significantly improved plant growth compared to non-inoculated trials.
