Opis:
The BAT-CELL Bio-Ambient-Tests method is based on the assessment of the influence of the actual toxicity of various types of gas mixtures on living cells, taking into account the additive synergism. Work has been carried out on the application of the BAT-CELL method for testing engine exhaust gases. The application of computational fluid mechanics using Ansys Fluent made it possible to analyse the flow of engine exhaust gases through the aspiration system used, including analysis of shear stress values and their uniformity distribution on the bottom wall of the sampler containing cell culture on the bottom wall of the sampler. The appropriate flow rate of exhaust gases through the aspiration system and the shape of aspiration tubing for the sampler were selected in order to enable uniform contact of gas particles with the cell surface and not to damage them mechanically. The simulation results were verified in real-life tests and confirmed the theoretical assumptions.

Opis:
Celem artykuły jest prezentacja autorskiej metody edukacyjno-wychowawczo-terapeutycznej NUUN (Nauczyciel–Uczeń–Uczeń Nauczyciel); skierowanej do uczniów, wychowanków, z którymi trudno się porozumieć na skutek bariery językowej, odmienności kulturowych oraz dla dzieci mających trudności w komunikacji na skutek cech osobowościowych, traum, innych ograniczeń. Treści zawarte w artykule są wynikiem poszukiwania przez autorkę nowego modelu edukacji w kontekście kolejnych zmian na świecie w tym, rewolucji technologiczno-informacyjnej pociągającej za sobą kryzys mentalny. Przedstawiono zagadnienie świadomości ucznia i nauczyciela jako cechy, która powinna przyświecać nowej edukacji, na której oparte będzie poznawanie świata, także w odwołaniu do świata niematerialnego w kontekście budowy człowieka jako ciała, umysłu i sfery duchowej. Opisano główne założenia metody polegającej na repozycjonowaniu roli nauczyciela i ucznia stawiając między nimi znak równości w procesie nauczania i odkrywania świata. Opisana jest waga samoświadomości nauczyciela i budowanie samoświadomości dziecka, poczucia własnej wartości oraz odkrycia talentu. Opisana metoda jest wynikiem wieloletnich obserwacji zachowań ludzi w odmiennościach kulturowych oraz pracy autorki w skrajnie trudnych warunkach pedagogicznych w szkołach w Azji i Ghanie w ośrodku dla dzieci ulicy.
The aim of this article is to present an original educational, pedagogical and therapeutic method NUUN (Teacher–Student, Student–Teacher). The method is addressed to students with whom one may experience difficulties in communication due to language barrier or cultural differences. The contents of the article are a result of the author’s search for a new educational model in the face of modern changes, including information technology revolution entailing mental crisis. There has been presented an aspect of the awareness of both students and teachers as a value that should dominate in new education and lead to discovering the surrounding world, including a non-material one, as a human being composed of body, mind and spirit. The article includes the main method’s assumption based on repositioning of the roles both of students and teachers by putting an equal sign between them in a process of teaching and discovering the world. There is an emphasis on the importance of self-awareness of teachers and building self-awareness and self-esteem among children as well as discovering their talents. The presented method is a result of many years of observation of human behavior in different cultures and the author’s experience of working in extremely difficult educational conditions in schools in Asia and Ghana in an institution for street children.

Opis:
The paper proposes an alternative approach to the dissemination of the mass unit in the context of the new definition of the kilogram. Considering the fact that redefinition allows mass to be directly realized at any value, the paper presents a model of the dissemination of mass which can be used for diferent series in grams, where the measurements are performed in the downward direction, but using 1 g as the reference standard (whose mass value is assumed to be determined after the redefinition using the capacitive or electrostatic techniques). The subdivision method presented (suitable for 1 weights) has as its starting point the approach used by Mihailov-Romanowski for the calibration of series in kilograms which uses an orthogonal system of equations. Thus, according to this method, a solution for obtaining the orthogonality of a system can be the use as defining standard of the ratio between the mass having the highest nominal value in the set and the standard (unit). The results obtained for a set of weights from 10 to 1 g using the subdivision method, in accordance with the Mihailov-Romanowski principle, are validated with those obtained with the multiplication method, where the measurements start from 1 to 10 g, as in the case of the kilogram series. The mass values obtained with both methods are equal, while the estimated uncertainties are slightly diferent, yet insignificant. The results obtained previously for the same sequence of weights using the traditional dissemination method, where the 1 kg standard is used as reference, are also presented in the paper. The results show that only three weights out of six have a mass value insignificantly diferent by 1 × 10-4 mg compared to those obtained with the methods presented in this article, but, in terms of uncertainty, there are some diferences. The way of disseminating the mass unit presented in this article can be extended to other diferent sequences of nominal values such as: (5 . . . 1) g, (20 . . . 1) g, (50 . . . 1) g or (500 . . . 100) g if the reference standard is 100 g.

Abstract: Study programmes in economics and management should be more focused on developing students’ critical thinking skills and the capabilities to solve practical problems. Case method is admittedly one of the best techniques to accomplish these goals. Thus, disseminating the benefits of case method in academic teaching as well as supporting case writing among scholars is of great importance. Despite the many proven benefits of the case method and the growing use of cases in teaching management and economics, it seems that the writing of cases is undertaken by not so many academics. There is evidence of the lack of support at smaller schools to potential case writers from administrators, in terms of motivation, recognition, training, time, and funding, and on the other hand, there is little awareness among faculty about international scholarships, available peer-reviewed publishing opportunities for cases, and peer support via international case conferences. This paper attempts to fill in the existing information gap and offer helpful guidance to faculty and school administrators. Aim: The aim of this paper is to support the development of case writing in the management and economics subjects by faculty of smaller universities where typically the local peer support is limited or non-existent, while the value of such academic research activity may be underestimated by school deans. The paper offers practical guidance on how to get international support while developing teaching cases. Design / Research methods: This paper is a policy analysis type of research. It is based on secondary sources as well as primary sources such as personal observations and experience of the author who has been teaching finance and business since 1995, has published the first case in 2015, has authored 10+ cases by early 2022, has received 3 international case writing awards, and has been elected to the Board of NACRA, the leading case research association in the U.S. Conclusions / findings: The use of case method in teaching management and economics has multiple benefits, including its virtuous role in school accreditations and industry-academia collaboration, as well as its powerful boost to the professional development of faculty. Faculty involvement however will remain limited unless the school deans and the accrediting bodies apply proper motivation to support academic case writing. The paper lists specific policy recommendations for promoting case research and case writing, which are feasible to implement in small universities with a limited budget. Originality / value of the article: There are currently no papers that present such an overview of the current academic case writing scene, case conferences, funding, peer-reviewed case publication opportunities, as prepared by the author based on the personal experience as finance professor and case writer. It is a unique and valuable practical guidance for faculty members who are looking to get involved in case writing or for deans who are thinking of feasible measures to promote case writing and case research by tapping into the existing global resources and opportunities.

Opis:
The paper aims to develop and apply a methodological approach that could help to reveal incentives and future strategies of key National Innovation System (NIS) players considering the influence of global social, economic, scientific, technological and ecological trends. To fulfil this aim, a blended foresight methodology was applied, grounded on the platform of economic and classic foresight theory and considering four possible directions for using foresight methods: investigating and building a common vision; supporting evidence-based decisions; promoting communication and participation; inducing transformation and integration into the decision-making process. The main results and findings of the research include a list of 19 global trends, defined from literature analysis and the author’s expert knowledge, a short description of their influence on key NIS players, including society, business, infrastructure and institutions, science, education and government; and mapping more than 35 different foresight methods that could be used for revealing incentives and future strategies of key NIS players. The article’s theoretical contribution to economic theory consists of several parts. First, a NIS conception is examined through the prism of global trends and a dynamic aspect, whereas it is mostly investigated from statistical and static perspectives. Second, applying foresight as an instrument for researching NIS as a system is a developing academic area with some theoretical gaps, considered in this article by designing a conceptional research framework. Third, blending different foresight methods is always a craft, and the approach applied in this article contributes to it. Finally, the article presents several important trends which will appear in NIS and its key players’ transformation in the nearest 5–10 years. From practical implications, this article could be useful for proactive policymakers in the field of science, technology and innovation policy at national and regional levels for designing and providing measures for supporting innovation systems effectively. Foresight practitioners and experts are offered useful, practical ideas of different foresight methods and their possible combinations for everyday activities.

The paper analyses the economic implications of the accession of New Member States (NMS) to the European Union (EU) in 2004 and 2007. The estimation effects of integration with the EU were carried out as a comparative case study using the synthetic control method (SCM) proposed by Abadie and Gardeazabal. Compared to previous studies analysing the effects of accession to the EU (Campos, Coricelli and Moretti), we check for the importance of the quality of economic institutions for the matching process of the analysed economies with their comparators. The results of the econometric analysis show a positive impact on the country performance 6 years and 12 years after accession to the EU. The gains from accession are large but not universal. For 5 of the 10 analysed countries the difference in levels of per capita gross domestic product (GDP) against the counterfactual is at least 30%.

Opis:
The doctrine of Adam and Eve as prototypes of New Adam and New Eve (the so-called theory of recapitulation) was first encountered in the epistles of the apostle Paul. Revealing the main feature of this teaching, the supreme apostle reports that the disobedience and sin that Adam and Eve committed were corrected by New Adam and New Eve (see: Rom. 5, 14-15). As a result, instead of the death of Adam and Eve and their descendants (by bodily birth), humanity received immortality, starting with New Adam and New Eve and their descendants (by spiritual birth). Subsequently, the pre-nicene christian writers, for example, Irenaeus of Lyon, Tertullian and Victorinus of Poetovio, resorted to the doctrine of Adam and Eve as prototypes of New Adam and New Eve. Developing the theory of recapitulation, Irenaeus of Lyon in his works — «Against heresies» and «Proof of the apostolic sermon» — used the epistles of the apostle Paul and the typological method of interpreting Holy Scripture. The saint of Lyon taught, first, that on that day (that is on friday), on which Adam was born, New Adam, or the Lord Jesus Christ, was born; secondly, on that day (that is on saturday), on which Adam violated the only commandment of God (see: Gen. 2, 16-17), the incarnate Son of God suffered. In addition, what the virgin Eve did not fulfill, being disobedient, since she ate the forbidden fruit, the Virgin Mary did, being obedient, since she gave birth to the Lord Jesus Christ. Following tradition in the presentation of the theory of cancer-capitulation, Tertullian in his treatise «On the flesh of Christ» uses the epistles of the apostle Paul, the works of Irenaeus of Lyon and the typological-mysterious method of interpreting Holy Scripture. The first latin theologian in his work resorted to analogies: the first is an uncultivated land, that is, since the first Adam was created from an uncultivated earth — the Second Adam was also created from an uncultivated earth, or was born from the Blessed Virgin Mary; the second — the heard word, that is, because through the heard word the first Eve sinned — the second Eve also through the heard word did not sin, or became the cause of the salvation of the entire human race. Developing the theory of recapitulation, Victorinus of Poetovio in his works — «On the сreation of the world» and «On the life of Christ» — relied on the epistles of the apostle Paul, the works of Irenaeus of Lyon and the typological method of interpreting Holy Scripture. The saint of Poetovio taught, first, that on that day (that is on friday), on which Adam was born, the incarnate Son of God was born; secondly, on that day (that is on saturday), on which Adam and Eve violated the only commandment of God (see: Gen. 2, 16-17), the Annunciation of the Blessed Virgin Mary took place and the Lord Jesus Christ suffered; and, thirdly, on that day (that is on the resurrection), on which God the Father and the Son of God created light, the conception of the Blessed Virgin Mary took place, the incarnate Son of God rose from the dead and the second time He will come to earth to judge all human genus.

With the increase in global spatial mobility the importance of migration policy (including integration policy) is increasing day by day, both in developed countries and new market economies. In the course of the research on migration policy various measures were constructed. Even though the particular measures relate to different areas of migration policy, they do not refer to the effectiveness of migration policy. The aim of this study is to assess the effectiveness of the integration of immigrants into the labour market in the countries that belong to the Organisation for Economic Co-Operation and Development (OECD) and to analyse the relationships between these effects and the integration policy adopted by the individual countries. The TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) method and the CRITIC (Criteria Importance Through Intercriteria Correlation) method were used in the research. The results indicate that the highest effectiveness of migration policy in terms of integration of immigrants into the labour market was reported in the following OECD countries: Iceland, Switzerland and New Zealand. The results also suggest that the higher the level of integration policy restrictiveness in a given country, the worse the effects in terms of integration of immigrants into the labour market that were noticed by this country.

The article is devoted towards the application of managerial accounting for deliverology development at the local government level in countries and comparing them to the stage of fiscal decentralisation implementation in Ukraine. The aim of the article is to show how the application of the managerial accounting approach in the public sector can contribute to the introduction of deliverology at the local level using Ukraine as an example. The methodology is based on the application of Difference in Difference method for the implementation of deliverology at the local government level. It has been proved that the use of multi-criteria decision-making methods in the analysis of the performance of budget programmes at the local level will contribute to the improvement of public services delivery. The main contribution of this study is to provide the basis for developing recommendations for the use of a single or uniform standard of electronic databases on regional development indicators and local budgets. This will help to ensure operational control over deviations of actual indicators from planned ones, as well as identify regions where local authorities are using resources inefficiently.

Opis:
The article presents theoretical and methodological premises of the doctoral thesis in which the European Union civil service and the civil service in selected member states (France, Spain, the Netherlands, Germany, Poland, the United Kingdom and Italy) are analysed. The civil service is formed by the legal and cultural determinants, specific standards, dysfunctions and tools of the civil service. Moreover some researchers maintain that the concept of the civil service can only be used with reference to the state. Presumably the term civil service of the European Union is deliberately avoided because it would raise the negative connotations related to the federalization of the EU. The author intends to verify this term by comparing the public service in the institutions of the EU with the civil service in several European countries. A key approach adopted in the thesis is the new institutionalism which combines the features of institutionalism and behaviourism. First-order methods are the comparative method and the systems method, while the second-order method is the simulation method. The qualitative and quantitative methods will also be applied. Such approaches and methods were selected in order to be mutually complementary as well as useful in verifying the research hypothesis.

The dissemination of social media and the growing resources of big data create both new opportunities for urban space analysis and new challenges for contemporary policy making. Among the sources useful from this standpoint there are, inter alia, photos posted on Instagram. They can easily become the basis for behavioural analysis of the quality of urban life based on complete sampling and conducted in the method of deskresearch. The article uses photographs published on Instagram for the purpose of exploratory analysis of land use on the examples of five parks located in New York. This makes it possible to determine the nature and ways of perception of selected spaces.

Opis:
In the paper presents two new patented of unconventional methods author’s and sleeve-type products of extruding [PL219182, PL221425]. The extrusion methods have been developed with the aim of reducing the energy and force parameters during the plastic forming of material. Traditional methods of extruding similar products are characterized by considerably higher extrusion force magnitudes. This results in substantial limitations and problems of an engineering nature. Moreover, the proposed methods of producing bottomed and bottomless sleeves are distinguished by the capability to minimize or totally eliminate the waste. The author’s methods of extruding long bottomless sleeves, presented herein, were used for developing a method for shaping inner toothing in spline sleeves. The theoretical analysis is based on thermomechanical simulation of the possibility of applying such processes to the extrusion of spline shafts with inner toothing. Next, the obtained results were compared with analogous parameters for classical indirect extrusion. The possibility of shaping inner toothing over the entire product length according to the proposed spline sleeve plastic forming methods was also explored.

Opis:
In this paper and for the first time, we describe and introduce a new extended direct algebraic method which is a new method for solving nonlinear partial differential equations arising in nonlinear optics and nonlinear science. By applying this method, we have constructed new solitary wave solutions for the unstable Schrödinger equation. A large family of traveling wave type exact solutions covering exponential, generalized trigonometric, rational and generalized hyperbolic functions to this equation is determined. The solutions are expressed in explicit forms.

Opis:
This paper studies a nonlinear partial differential equation known as the nonlinear longitudinal wave equation which describes the propagation of optical solitons in a magnetoelectro-elastic circular rod. Mentioned task is performed by solving this nonlinear equation using the well-designed modified Kudryashov method, producing a series of new optical solitons. The capability of the modified Kudryashov method in handling the nonlinear longitudinal wave equation in a magnetoelectro-elastic circular rod is confirmed.
