Методика проверки гипотезы о независимости случайных величин, основанная на непараметрическом алгоритме распознавания образов, используется при анализе неоднозначных зависимостей. Алгоритм распознавания образов соответствует критерию максимального правдоподобия. Оценивание законов распределения в классах осуществляется по исходным статистическим данным в предположении о независимости и зависимости сравниваемых случайных величин. Для оценивания плотностей вероятностей в классах используются непараметрические статистики Розенблатта - Парзена. Коэффициенты размытости ядерных функций в непараметрических оценках плотностей вероятностей в классах определяются из условия минимума их средних квадратических отклонений. В этих условиях вычисляются оценки вероятностей ошибок распознавания образов в классах. По минимальному их значению принимается решение о независимости либо зависимости случайных величин. Проверяется гипотеза о достоверном отличии вероятностей ошибок распознавания образов в классах. Применение предлагаемой методики позволяет обойти проблему декомпозиции области значений случайных величин на интервалы, что свойственно критерию Пирсона. Сравнивается эффективность предлагаемой методики с критерием Пирсона. Приводятся результаты вычислительных экспериментов с применением исследуемых критериев при анализе неоднозначных зависимостей между случайными величинами.

The method of hypothesis testing of the independence of random variables, based on a nonparametric pattern recognition algorithm, is used in the analysis of ambiguous dependencies. The pattern recognition algorithm meets the maximum likelihood criterion. The estimation of the distribution laws in classes is carried out according to the initial statistical data under the assumption of independence and dependence of the compared random variables. Nonparametric statistics of the Rosenblatt - Parzen type are used to estimate probability densities in classes. The blur coefficients of kernel functions in nonparametric estimates of probability densities in classes are determined from the condition of the minimum of mean square deviations. Under these conditions, estimates of the probabilities of pattern recognition errors in classes are calculated. According to their minimum value, a decision is made on the independence or dependence of random variables. The hypothesis of a significant difference in the probabilities of pattern recognition errors in classes is tested. The application of the proposed technique allows us to bypass the problem of decomposition of the range of values of random variables into intervals, which is typical for the Pearson criterion. The effectiveness of the proposed method is compared with the Pearson criterion. The results of computational experiments using the studied criteria in the analysis of ambiguous dependencies between random variables are presented.

Представлены экспериментальные данные по изучению фононных и оптических свойств нанопроволок GaAs ориентации (111), расположенных на золотой подложке с помощью методов спектроскопии комбинационного рассеяния света (КРС) и фотолюминесценции (ФЛ). Структурные параметры нанопроволок были определены методами атомно-силовой (АСМ) и сканирующей электронной микроскопии (СЭМ). В спектрах микроКРС и микроФЛ отдельной нанопроволоки GaAs наблюдаются моды оптических фононов GaAs и их обертонов, вплоть до третьего порядка, и полоса экситонной фотолюминесценции. В спектрах микроФЛ проявляется анизотропия интенсивности ФЛ в нанопроволоках, причём максимальный/минимальный сигнал наблюдается при направлении вектора поляризации вдоль/поперёк проволоки. Выполнено картирование наноФЛ отдельной нанопроволоки GaAs с пространственным разрешением 20 нм, что существенно меньше дифракционного предела. При переходе к нанометровым масштабам обнаружено плазмонное усиление сигнала ближнепольной экситонной наноФЛ, обусловленное металлизированной АСМ-иглой.

The paper presents experimental data on phonon and optical properties of (111)-oriented GaAs nanowires on a gold substrate studied by means of Raman scattering and photoluminescence (PL). The structural parameters of the nanowires are determined by atomic force and scanning electron microscopy (AFM and SEM, respectively). In the micro-Raman and micro-PL spectra of a single GaAs nanowire, phonon modes of GaAs and their overtones up to the third order and an exciton photoluminescence band are observed. In the micro-PL spectra, anisotropy of the PL intensity in nanowires is revealed, and the maximum/minimum signal is observed when the polarization vector is directed along/across the wire. Nano-PL maps of a single GaAs nanowire with a spatial resolution of 20 nm are obtained, which is significantly smaller than the diffraction limit. Plasmon enhancement of the near-field exciton nano-PL in the vicinity of the metallized tip of the AFM microscope is detected.

Сплошные и пористые плёнки сплавов Si1-xGex с содержанием германия около 40 % и толщиной 3-4 мкм, сформированные на монокристаллическом кремнии методом электрохимического осаждения германия в матрицу пористого кремния с последующим быстрым термическим отжигом при температуре 950 °C, исследованы методами спектроскопии комбинационного рассеяния света (КРС), оптической спектроскопии и сканирующей электронной микроскопии. На основе спектров, снятых в стоксовой и антистоксовой областях частот с использованием статистики Больцмана и закона теплопроводности Фурье, определены коэффициенты теплопроводности плёнок, которые составляют 7-9 и 3-6 Вт / (м ⋅ К) для сплошной и пористой плёнок соответственно. Низкая теплопроводность пористой плёнки объясняется дополнительнымфононным рассеянием на развитой поверхности пор. Перспективность применения таких плёнок в термоэлектрических преобразователях обеспечивается простотой и масштабируемостью способа изготовления сплава, а также его низкой теплопроводностью.

Solid and porous films of the Si 1-xGex alloys with a germanium content of about 40% and a thickness of 3-4 μm, formed on single-crystal silicon by electrochemical deposition of germanium into a porous silicon matrix followed by rapid thermal annealing at a temperature of 950 °C, are studied by Raman spectroscopy, optical spectroscopy, and scanning electron microscopy. Based on the Raman spectra taken in the Stokes and anti-Stokes frequency regions, using Boltzmann statistics and the Fourier thermal conductivity law, the thermal conductivity of the films is determined, which is found to be 7-9 and 3-6 W/(m×K) for a continuous and porous film, respectively. The low thermal conductivity of the porous film is explained by additional phonon scattering from the developed pore surface. The prospect of using such films in thermoelectric converters is ensured by the simplicity and scalability of the method for manufacturing the alloy, as well as its low thermal conductivity.

Приведены результаты по изменению параметров псевдо-МОП-транзисторов на мезаструктурах кремний-на-сапфире (КНС) при облучении быстрыми тяжёлыми ионами (БТИ) Xe+26 (150 МэВ) и Bi+51 (670 МэВ) до флюенса 2 ⋅ 1011 см-2, свидетельствующие о накоплении механических напряжений и зарядов в промежуточных сегнетоэлектрических (Fe) слоях плёнок HfO2 (HO) толщиной 20 нм, Hf0,5Zr0,5O2 (HZO), ламинированных вставками из монослоёв Al2O3 (HA, HZA) или без них. Гетероструктуры КНС формировались прямым сращиванием и водородным переносом плёнки кремния (500 нм) с предварительно нанесёнными методом плазменно-стимулированного атомно-слоевого осаждения нанослоями HA, HZA на сапфир. Электрофизические параметры определялись из стокозатворных характеристик ( Ids-Vg ) псевдо-МОП-транзисторов c вольфрамовыми сток/истоковыми электродами толщиной 100 нм, нанесёнными магнетронным напылением на КНС-мезаструктуры через литографическую маску. Сравнение этих характеристик с данными рамановского рассеяния показало соответствие введённых облучением БТИ механических напряжений сжатия в кремнии с отношениями объёмов треков Xe и Bi в сегнетоэлектрике HA и сапфире.

The results of changing the parameters of pseudo-MOS-transistors on silicon-on-sapphire mesastructures under irradiation with swift heavy ions (SHI) Xe+26 (150 MeV) and Bi+51 (670 MeV) to a fluence of 2´1011cm-2 are presented. They reveal the accumulation of mechanical stresses and charges in intermediate ferroelectric layers of HfO2 (HO) films 20 nm thick and Hf0.5Zr0.5O2 (HZO) films, laminated with Al2O3 monolayer inserts (HA, HZA) or without them. SOS heterostructures are formed by direct splicing and hydrogen transfer of 500 nm silicon films on HA and HZA nanolayers pre-deposited by plasma-enhanced atomic layer deposition on sapphire. The electrical parameters are determined from the Y-MOSFET drain-gate characteristics ( Ids - Vg ) with 100 nm thick drain-stock W electrodes deposited by magnetron sputtering on the SOS mesastructures through a lithographic mask. A comparison of these characteristics with Raman scattering data shows that the mechanical compression stresses introduced by BTI irradiation in silicon correspond to the volume ratios of Xe and Bi tracks in HA ferroelectric and sapphire.

Published: September 2024

The kinetics and mechanism of hydrogen evolution on the MoSi2 electrode in x M H2SO4 + (0.5 - x) M Na2SO4 (x = 0.50; 0.35; 0.20) solutions have been studied. The cathodic polarization curves of MoSi2 in the studied solutions are characterized by Tafel region with a slope of (-0.070)±0.002 V. The reaction order of the cathodic process with respect to hydrogen ions at the potentials of Tafel region is ~1.0; the derivative of the electrode potential with a change in electrolyte acidity is ~0.072 V. The impedance spectra of the MoSi2 electrode in the studied potential range have the shape of a semicircle located in the capacitive half-plane, with the centre in the region of positive values of the imaginary impedance component; in the region of the highest frequencies, a short straight section is recorded on the impedance plots, indicating the presence of pores in the surface layer of the electrode. To describe the hydrogen evolution reaction on MoSi2, we used an equivalent electrical circuit, the Faraday impedance of which consists of series-connected charge transfer resistance (R1) and a parallel R2C2Zd-chain responsible for the adsorption of atomic hydrogen on the surface and its diffusion into the depth of the electrode material. The equivalent circuit also includes the solution resistance (Rs) and the double layer capacitance impedance, which is modeled by the constant phase element CPE1. It is shown that the hydrogen evolution reaction on molybdenum disilicide in a sulphuric acid electrolyte proceeds along the discharge - recombination route with a quasi-equilibrium discharge stage when the Temkin logarithmic isotherm for adsorbed atomic hydrogen is fulfilled. The hydrogen evolution reaction is complicated by hydrogen absorption proceeding in the mode of solid-phase diffusion kinetics.

Experiences of Students with the Implementation of the Theme of Shoah into Teaching
Authors: Mašát Milan
Published: September 2024

Aim. In this paper, we present selected results of a research survey conducted among teacher education students to determine their preconceptions about the implementation of the events of the Shoah into teaching at different levels of education.
Methods. In this paper we answer the following research questions: Would the respondents welcome a greater curricular anchoring of the Shoah in the Framework Curriculum for Primary Education? Are prospective teachers interested in various books on the Shoah in their spare time? What methods and forms of work were used in teaching in connection with the events of the Shoah at the graduated primary school? In which year of primary school do respondents think it is appropriate to include Shoah topics? Are the respondents satisfied with the level of integration of the Shoah phenomenon into teaching at the Faculty of Education of Palacký University in Olomouc?
Results. Most respondents believe that the Shoah phenomenon is only suitable for integration at the lower-secondary school. This preconception stems mainly from the respondents´ previous experience in primary schools.
Conclusion. The results point to the fact that the transformation of the perception of the defined events, and the related broader possibilities of their application in Czech institutional teaching, will be quite complex.
Cognitive value. It is necessary to begin to perceive the Shoah also in a certain transcendental, visceral level and, based on the internalisation of the resulting feelings, to begin to build pupils´ awareness of the importance of democracy, freedom, or tolerance.

The Predestination Functions in the Structure of the Dream in Mitrush Kuteli’s Opus
Authors: Dema Alma , Tershalla Risvan
Published: September 2024

Aim. Dreams are usually understood as a mechanism to transform thoughts into images. We use the lexeme mechanism, because the way this happens is not always identifiable or decipherable, and the level of difficulty depends on the density of the symbols that need to be decoded. Dream is said to be a sequence of images, a vision or a close connection with the reality. Having in consideration these statements this paper, aims to unravel and understand the dream and function of the predestination in the long narrative “Great is the horror of Sin, Tat Tanushi of Bubëtima”, by 30’s Albanian writer Mitrush Kuteli (2011).
Methods. The methods to sort out the aim are the text analysis, interpretive and comparative ones. The text analysis will involve content analysis, thematic analysis, and discourse analysis.
Results. The link between life and death, as depicted through the shifts from dreams to the afterlife, offers a distinct outlook on the world. In Mitrush Kuteli’s prose, the rich transformations both mock the long-standing fear of death and invite the living to keep enjoying life’s pleasures even beyond death.
Conclusions. We have made efforts to assert our thesis that in “Great is the horror of sin, Tatë Tanushi of Bubëtima” (2011) the dream has a warning function as well as a fantastic biblical one. The conclusion is both philosophical and fantastical biblical.

Published: September 2024

Aim. Military operations in Ukraine have caused signs of mental trauma in the combatants. Such individuals need active psychological rehabilitation involving effective methods. One of them is the use of interactive psychological simulators that help to rethink one’s perception of reality and oneself in it, learn new types of behaviour. The aim is to identify the effectiveness of using interactive psychological simulators in improving the psycho-emotional state of combatants.
Methods. The following methods were employed during the diagnostics: Diagnosis of Psychological Safety of a Person (DPSP-88), Lemur-Tessier-Fillion Psychological Stress Measure (PSM25), Beck’s Depression Inventory (BDI), Taylor Manifest Anxiety Scale (TMAS). Descriptive statistics and Student’s t-test were applied for statistical processing.
Results. The study proved that the use of an interactive psychological simulator by combatants increased their Psychological Safety Index (t = 8.42; p≤0.001), reduced stress (t = 4.39; p≤0.001), depression (t = 5, 14; p≤0.001), and anxiety (t = 5.43; p≤0.001). This makes it possible to expand the range of psychological rehabilitation of combatants through the introduction of psychological simulators.
Conclusion. The obtained results are important for psychologists and rehabilitators, as they prove the effectiveness of the use of psychological simulators in the psychological rehabilitation of combatants. This can improve the process of psychological recovery of the military, contribute to their social and psychological adaptation, resocialisation. Based on the obtained results, it is planned to expand the possibilities of using psychological simulators in the rehabilitation of combatants. Their introduction into the mandatory system of providing assistance to victims of hostilities will reduce the time of their psychological recovery.

Authors: Hernández-Lloret Carmen-María , Álvarez-Castillo José-Luis , Espino-Díaz Luis , González-González Hugo , Fernández-Caminero Gemma
Published: September 2024

Aim. Diversity and inclusion are part of the third mission of higher education institutions. One of the dimensions that must be considered in the process of institutionalising inclusion is research. Inclusive research allows for critical research and reflection on certain fundamental issues on the road to democratic citizenship, making a positive impact on people's lives while contributing to social change and transformation. However, the literature has evidenced barriers in the institutionalisation effort, such as those posed by the market conception. In this context, the study presented here analyses the involvement of higher education research with diversity, as well as its weaknesses and strengths, and finally contributes to the identification of proposals for improvement and good practices for inclusive research.
Methods. This work was based on assumptions of the interpretative paradigm, using virtual, one-on-one, semi‐structured interviews with Spanish researchers from different universities –most of them leading national projects on inclusion.
Results. The results show that research on diversity is beginning to be incorporated as an essential modality in university agendas. In parallel, it is thought that academic capitalism and competitiveness have pierced conceptions of research quality, and in doing so, diversity and inclusion principles are called into question.
Conclusions. Currently, the strengths of inclusion research in higher education are not as robust as the weaknesses. Proposals are made for the improvement of inclusive and democratic research, and four principles are set out to promote the institutionalisation of research on inclusion in universities.
Teaching Human Geography Sustainability: The Concept of the Anthropocene as a Didactic Tool for Higher Education
Authors: Brauer Rene
Published: September 2024

Thesis. This critical reflection outlines the didactical challenge of teaching human geography in higher education, focusing on the concept of the Anthropocene as a tool for highlighting sustainability issues.
Concepts. The critical reflection discusses the diverse knowledge production traditions, including modernist, postmodernist, and post-postmodernist approaches. It highlights the importance of understanding the ontological and epistemological assumptions underlying these frameworks, in relation to human geography, the concept of the Anthropocene and sustainability.
Results and conclusion. The suggestion is a fourfold strategy for improving human geography education: emphasizing the relevance of knowledge production, understanding its impact on the student-teacher relationship, enriching teaching with epistemological discussions, and presenting the Anthropocene as a contested ontological concept rather than a predefined framework.
Originality. This critical reflection offers a novel perspective on human geography higher education in how the concept of the Anthropocene can be used for didactic purposes. The paper argues that the concept of the Anthropocene can function as a didactic tool for higher and human geography education, by drawing out the human element within scientific knowledge production.

Published: September 2024

Introduction. It is possible to increase the separating of loose grain on the lattice bottom of the combine harvester feeder house by removing most of the light impurities from the combed heap using an inertial cleaning system built into the combing adapter body.Aim of the Study. The study is aimed at developing an inertial system for separating light impurities in the combing header body and optimizing its main parameters.Materials and Methods. The object of the study was a large-scale model of a pneumatic cleaning device to simulate the motion of air and components of a combed grain heap inside the combing adapter body. It was a two-factor experiment with three variations of the air flow velocity (4.5; 5.5; 6.5 m/s) and the width of the air channel (0.26; 0.29; 0.32 m). The studies were conducted on a combed heap of Moskovskaya 56 wheat with a moisture content of about 12%. As a parameter for optimization and response function, a portion of the combed heap was selected from the body of the installation with an air flow.Results. According to the results of the experimental studies, it was found that the air flow velocity has a greater effect on separating glumes than the width of the air channel. A simultaneous increase in both factors leads to an improved separation. At the same time, if increasing the air flow velocity ensures a stable increase in the proportion of the combed heap and is limited only by the air velocity at which grain appears in the combed heap along with the glumes, then changing the channel width allows achieving the parameter optimal value.Discussion and Conclusions. The use of an inertial cleaning system makes it possible to remove almost completely light impurities from the combed heap. The optimal parameters of the device are: channel width 0.28...0.3 m, air flow velocity 6...6.5 m/s.

Introduction. The performance of precision seeders depends on many factors, including the functionality of their dosing systems, the modernization of which is possible only on the basis of patterns, which allows forecasting the indicators of single seed placing into a furrow.Aim of the Study. The study is aimed at analyzing the influence of the diameter of the suction holes of seed-placing units and the rarefaction created in them on the characteristics of placing seeds of the main row crops.Materials and Methods. The results of the study were obtained based on a series of experiments on sowing corn and sunflower seeds using an MS-8 seeder, the operation principle of which can be considered typical for vacuum seed-placing units.Results. There have been obtained empirical dependences of the particular features of zero and group placing seeds of such row crops as corn and sunflower on the area of the suction holes and the rarefaction in the vacuum chamber.Discussion and Conclusion. The quantitative estimates obtained may differ for seeds of the same crop, but having different technological properties. The general factor is that the frequency of missing seeds is proportional to the suction force magnitude in the working plane of the metering element, regardless of its area. At the same time, the probability of double seed placing depends on the area of the metering ports with a constant suction force, a decrease in their diameter leads to a decrease in the frequency of double seed placing. The data obtained allow considering joint variations in the magnitude of the rarefaction in the vacuum chamber and the diameter of the suction holes as effective tools for improving the seed placing quality.
Dispersive solid-phase extraction using ZIF-8 coupled to high performance liquid chromatography–tandem mass spectrometry for the detection of 80 pesticides in poultry egg and their products

Published: September 2024

People are consuming increasing amounts of poultry eggs and their products, and their safety is always a public concern. However, the complex composition of poultry eggs and their products, particularly the proteins and lipids, can easily cause matrix effects, requiring the use of sorbents to remove these components to avoid affecting the detection results. Zeolitic imidazolate framework-8 (ZIF-8) is a MOF material with high specific surface area, high porosity, and high stability, making it widely used as a sorbent in pesticide residue detection. In this study, we evaluated the performance of ZIF-8 compared to classic solid phase extraction (SPE) and Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) in the pretreatment step. The results showed that ZIF-8 could better reduce the matrix effect in poultry eggs and their products. After optimizing the extraction solvents, chromatographic and mass spectrometric conditions, and pretreatment processes, we established a method using ZIF-8 as a sorbent combined with high performance liquid chromatography–tandem mass spectrometry (HPLC-MS/MS) for the detection of 80 pesticide residues in seven different types of poultry eggs and their products, yielding satisfactory results. All the target analytes showed good linearity, both with values of r2 > 0.996. The average recovery and coefficients of variation (CVs), expressed as relative standard deviations, ranges from 72.5% to 113.2% (chicken egg) (CV: 0.1%–12.9%), 72.2%–114.2% (salted duck egg) (CV: 0.1%–9.8%), 70.3%–105.6% (goose egg) (CV: 0.1%–12.0%), 70.9–120.4% (marinated egg) (RSD: 0.1%–14.8%), 70.7%–108.5% (duck egg) (CV: 0.1%–12.3%), 71.1%–105.0% (quail egg) (CV: 0.2%–5.6%), 70.7%–111.5% (century egg) (CV: 0.1%–13.4%). The values of limit of detection (LOD) and limit of quantification (LOQ) were, respectively, ranging from 0.15 to 0.85 μg kg−1 and 0.34–2.6 μg kg−1. When this method was applied to the detection of real samples, one chicken egg sample was found to contain 0.013 mg kg−1 of fipronil, and one marinated egg sample was found to contain 0.0087 mg kg−1 of thiamethoxam, indicating the necessity of stringent safety monitoring for poultry eggs and their products.
The origins of the East Greenland Coastal Current on the Northeast Greenland Shelf: a comparison of two reanalysis products
Authors:   ,   Massachusetts Institute of Technology, Vianco Sara L. ,   Woods Hole Oceanographic Institution
Published: September 2024

The East Greenland Coastal Current (EGCC) carries some of the freshest outflow from the Arctic southward along the East Greenland Shelf and into the Nordic Seas and subpolar North Atlantic. How this fresh water initially flows onto the Northeast Greenland Shelf (NEGS) and feeds the EGCC is not well known due in part to the lack of observations in the region. In this thesis, I use two ocean reanalyses, the Regional Arctic Ocean/sea-ice Reanalysis (RARE) and Global Ocean Physics Reanalysis (GLORYS) to explore the structure and dynamics of the ocean circulation on the NEGS. To validate the use of these products in the region, I compare the reanalysis products to the Fram Strait Arctic Outflow Observatory for the period of 2003-2019. In the mean, RARE is too warm and salty compared to the moorings, while the properties in GLORYS track more closely to the observations. However, the observed velocity field is better represented in RARE than GLORYS. From there, I analyze the cross-shelfbreak flow from 74°N to 81.5°N in the two reanalysis products, and conclude that transport onto the NEGS of waters fresher than 34 salinity is driven by an Ekman circulation that arises from along-shelfbreak winds and a widening shelf south of 81.5°N. The enhanced transport of fresh water also shifts the isohalines across the shelfbreak, directing a geostrophic flow onshelf between 81°N and 79°N. The convergence of fresh water on the NEGS initiates the EGCC as an identifiable and distinct feature around 80°N in RARE, uniting the EGCC along the southwest coast of Greenland and its northern counterpart, the Polar Surface Water (PSW) Jet. In GLORYS, the EGCC is not present throughout the domain, though there is a weak net southward flow on the NEGS. The EGCC in RARE is primarily buoyancy-driven, though the along-coast winds likely play a major role in maintaining the density front that supports the EGCC. Results from this thesis have implications for the transport and fate of Arctic and Greenland-sourced fresh water, and stratification in the high latitude North Atlantic and Nordic Seas.
Uchodźstwo jako wyzwanie edukacji międzykulturowej

The article presents the author’s concept of the continuum of intercultural relations referred to the cultural differences concerning refugees. This concept is based on the distinguishing of four stages of relationships: narrowly understood tolerance, cognitive interest, intercultural dialogue and cultural symbiosis. The ordering criteria used to distinguish the stages were: the sign of emotions related to the culturally Other, the sociocultural identity of the interacting individuals (especially people from the society that receives refugees), and the presence or absence of direct interaction between an individual representing the receiving society and the refugee. The concept of the continuum is presented against the background of the ideas underlying the emergence and development of the idea of intercultural education in Poland.
Japoński synkretyzm wyznaniowy
Authors:   Uniwersytet Wrocławski, Pilarska Justyna
Published: September 2024

Syncretism is a conceptual model that signifies the alliance, amalgamation, or combination of the assumptions of different religious, philosophical and cultural systems that are objects of interest in cultural, religious and social studies. Nevertheless, less attention has been paid to this process as an educational phenomenon. The purpose of this article is to provide an overview of the issues related to Japanese religious syncretism. It comprises the presentation of the main religious currents and spiritual traditions present in contemporary Japanese culture, as well as the idiosyncrasies associated with their peculiarities that carry the potential for informal cross-cultural education. This translates into some peculiar features of the cultural identity of the Japanese with their eclectic and inclusive qualities. In contrast to the negative connotations associated with syncretism in the context of the European cultural milieu and Christian dynamics, Japanese syncretism in this regard has positive connotations because it implies reconciliation between religious traditions and communities that would otherwise be considered as competing with each other. Insights into the nature of religious syncretism in contemporary Japan as a process of heterogeneous fusion of faiths and beliefs (and the resulting traditions, rituals and symbols) present in the public space and sacred architecture, and identified in cultural discourse, will specify the capital for cross-cultural learning and cross-religious tolerance.

Ethnic diversity in the United States is a dynamic phenomenon that affects all aspects of the country’s social, economic and cultural life. This is one of the characteristics that defines American identity and makes the United States one of the most diverse countries in the world. The article focuses on the identity of young Americans of Polish and Tibetan origins living in the Tri-State Area (Connecticut, New Jersey and New York). Students attending Polish and Tibetan Saturday Schools were selected for the study. These are two distinct ethnic groups, but it is assumed that maintaining the cultural heritage of their ancestors is what characterizes both of them. The research results confirm this thesis and indicate that the sense of identity is a natural need of a young person, expressed in a dual cultural pattern and a developmental task that should be undertaken. In both studies, a strong sense of pride in ethnic origin emerged, although it was articulated in different ways by young people. Students from both groups presented high cultural competences in their country of origin and country of residence.

The article contains considerations on intercultural education in Germany based on the example of Familienzentrum Lebenshilfe Elmshorn day care centres. Against the background of these considerations and referring to the thesis that early intercultural education provides an opportunity to develop lasting competences in the field of broadly understood coexistence, the German concern for intercultural education, care, help and support is presented. The Federal Assisted Living Association in the district of Pinneberg offers initiatives in this area through six integrated day care centres in Elmshorn, Pinneberg, Appen-Etz and Wedel. On the basis of the analysis of the activities undertaken in the city of Elmhorn and in day care centres, integration activities are shown – the ones that take place both in an intercultural perspective and in the family space. The article emphasizes that early intercultural education broadens thinking about education, understanding that a child is a learning entity striving for self-fulfillment, developing their own strength and possibilities in the process of “dialogue” with an adult. Early cultural education is also a path to peaceful coexistence based on mutual knowledge and understanding.

The article adopts a cultural understanding of the experiences of people with disabilities. Its purpose is an attempt to discuss disability as a minority culture in the context of the opportunities presented by intercultural education. From the perspective of the sociology of minority groups, the extent to which the dominant group’s perception of minority as cultural one is shared by the minority itself is relevant. In order to look at in-group concepts of education (using the Klon/Jawor database), the documents of NGOs from Lesser Poland Voivodeship involved in the education of people with disabilities were analyzed. The article refers to the minority nature of disability, the culture of people with disabilities, the state of expert literature on the education of this minority, and the results of our own research. It is based on an analysis of the literature on the subject and a study of the data collected from organizations dealing with people with disabilities, which set goals and tasks of an educational nature. The results of the conducted research indicate that there is a small number of initiatives aimed at building a culture of disability and that they are scattered, which in turn implies a lack of an institutional network of disability culture (at least in Lesser Poland Voivodeship).
The Effect of Preferences in Abstract Argumentation under a Claim-Centric View
Authors: Bernreiter Michael , Dvořák Wolfgang , Rapberger Anna , Woltran Stefan
Published: September 2024

In this paper, we study the effect of preferences in abstract argumentation under a claim-centric perspective. Recent work has revealed that semantical and computational properties can change when reasoning is performed on claim-level rather than on the argument-level, while under certain natural restrictions (arguments with the same claims have the same outgoing attacks) these properties are conserved. We now investigate these effects when, in addition, preferences have to be taken into account and consider four prominent reductions to handle preferences between arguments. As we shall see, these reductions give rise to four new classes of claim-augmented argumentation frameworks. These classes behave differently from each other with respect to semantic properties and computational complexity, but also in connection with structured argumentation formalisms such as assumption-based argumentation. This strengthens the view that the actual choice for handling preferences has to be taken with care.

Authors: Ferro Rafael
Published: September 2024

Esta pesquisa exploratória-descritiva analisou o panorama evolutivo dos projetos de pesquisa associados aos Programas de Pós-graduação brasileiros que estão relacionados diretamente com a pesquisa em Gastronomia. Para tanto, foram sistematizados os Dados Abertos disponibilizados pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes) sobre os projetos de pesquisa associados aos docentes dos Programas de Pós-graduação (PPGs). A análise de conteúdo foi a técnica utilizada para o tratamento dos dados. Conduziu-se uma busca lexical através de termos relacionados à Gastronomia para identificar os projetos pertinentes. Após análise do resultado dessa busca, 107 projetos de pesquisa compuseram o corpus. As seguintes variáveis foram definidas a partir da base de dados consolidada: a) tipo de projeto; b) ano da coletada da informação sobre o projeto; c) Instituição de Ensino Superior; d) título do PPG; e) Área e Subárea de conhecimento da Capes em que o PPG estava associado. As variáveis foram tratadas de forma a apresentar o panorama evolutivo desses projetos. As descrições dos projetos foram tratadas a posteriori, resultando em 11 categorias temáticas. Os resultados apresentados reforçam a inerente multidisciplinaridade, multiplicidade temática e teórico-metodológica e a institucionalização da pesquisa em Gastronomia no Brasil.
Influência lusitana na culinária japonesa em técnicas que favorecem o aproveitamento de alimentos
Authors: Ide Laura Kiyoko , Silva Carlos Alberto Figueiredo da , Moraes Arlete Gomes Guimarães
Published: September 2024

O presente artigo apresenta como temática de reflexão a influência gastronômica da cozinha portuguesa na culinária do Japão, fato que remete ao intercâmbio cultural que envolveu os dois países ainda no século XVI. O objetivo da pesquisa consiste em evidenciar elementos da culinária portuguesa que foram culturalmente integrados à gastronomia japonesa e que influenciaram na adoção de técnicas e práticas culinárias que favorecem o aproveitamento integral dos alimentos Trata-se de uma temática relevante, visto que as cozinhas portuguesa e brasileira estão fortemente entranhadas e após o fluxo migratório registrado no início do século XX também a culinária japonesa se fundiria no Brasil com elementos próprios, cujos benefícios já se pode visualizar. Para alcançar tal objetivo foi necessário realizar uma retrospectiva histórica que esclarece a influência cultural lusitana entre os japoneses após os primeiros contatos entre os dois povos. A culinária desenvolverá, a partir das técnicas herdadas dos portugueses, receitas que visam especialmente o aproveitamento integral dos alimentos evitando o desperdício que desencadeia prejuízos econômicos, sociais e ambientais. A metodologia utilizada na pesquisa tem caráter qualitativo e se caracteriza pela técnica da pesquisa bibliográfica.
