The specialized knowledge of middle school teachers concerning the concept of function
Authors: Slabý Matej , Semanišinová Ingrid , Climent Nuria
Published: July 2023

This study presents research focusing on in-service mathematics teachers and their approach to tasks aimed at developing of functional thinking. The analysis is based on the model of The Mathematics Teachers' Specialised Knowledge -- model MTSK by Carrillo et al. (2018). The research question is the following: What ``specialised knowledge'', in the sense of the MTSK framework, is revealed when a~middle school teachers solve and discuss the selected tasks? The research was conducted with 9 teachers, who voluntarily participated in the professional development. The teachers solved a~set of 30 tasks that were selected with a~focus on 4 aspects of the concept of function, different representations and transitions between them and different actions that learners engage in the task solving. In this study, we analysed the teachers' written solutions and the discussion with the teachers about a~particular task. Reflecting on their work as learners was very important in moving from dealing with the mathematics itself to shifting to developing their knowledge of mathematics teaching (KMT) and knowledge of features of learning mathematics (KFLM) in terms of the MTSK framework. The results helped us to identify gaps in teachers' specialised knowledge and consequently will help us to improve professional development courses for both in-service and pre-service teachers.

Мета дослідження – проаналізувати результати дослідження українських вчених, у яких цілісно розкриваються їхні погляди на періодизацію сучасної російсько-української війни. Методологія дослідження спирається на принципи історизму, системності, об’єктивності, а також на методи історіографічного аналізу і синтезу. Наукова новизна праці полягає у тому, що вперше в українській історичній науці проаналізовані погляди українських вчених, передовсім істориків, на періодизацію сучасної російсько-української війни. Висновки. Підсумовуючи аналіз досліджень українських учених із періодизації сучасної російсько-української війни, варто відзначити відносно невелику частину праць з означеної проблематики у порівнянні із опублікованими сотнями наукових досліджень різних аспектів проблеми. Уважаємо, це обумовлюється тим, що сучасна війна ще не є завершеним історичним процесом. Тому сформувати її періоди, етапи, очевидно, зарано, та й доволі складно, бо неможливо спрогнозувати подальший розвиток ситуації. Водночас уже наявні наукові доробки, у яких їхні автори (Павло Гай-Нижник, Олеся Куцька, Михайло Гребенюк, Михайло Щипанський, Валерій Грицюк, Олександр Лисенко, Сергій Сегеда, Володимир Трофимович, Віталій Бенчук та ін.) роблять спроби не тільки виокремити періоди, але й охарактеризувати їх. Відзначимо, що за змістовним та фактологічним наповненням вони досить суттєво відрізняються між собою. Звісно, що питання періодизації російсько-української війни українські та закордонні вчені ще неодноразово будуть обґрунтовувати власні підходи до виокремлення відповідних періодів і етапів, що вважаємо є цілком закономірним та важливим, враховуючи необхідність продовження загальних студій із цих питань.

Анотація. Мета дослідження. У статті увага зосереджена на дослідженні еволюції логіки мислення та дій агресорів у рамках сучасної російсько-української війни, насамперед керівництва держави-агресора – Російської Федерації. Методологія дослідження. Авторами показано необхідність застосування історико-системного методу в контексті окресленої проблематики. Новизна роботи. Проаналізовано специфіку мислення та механізми дій російських агресорів в контексті зв’язків між внутрішньою і зовнішньою політикою РФ. Мотиви й загалом раціональність агресивних дій російського керівництва проти України розглянуто зокрема у порівнянні з логікою агресії, притаманною й іншим претендентам на світову першість (Наполеон Бонапарт, Адольф Гітлер), простежено ідейні зв’язки між людиноненависницькою концепцією рашизму та іншими різновидами нацистсько-фашистської ідеології та парадигми міжнародних відносин. Висновки. Показано, що сучасна РФ у своєму розвитку в багатьох аспектах повторює моделі минулого інших країн (Франція, Британія, Німеччина, Японія та ін.), що загалом вже пройшли імперський, експансіоністський етап своєї історії. Також має місце ідеалізація, фальсифікація і навіть спроби певного відтворення (насамперед у формі політичних репресій) історичного досвіду СРСР і Російської імперії. Проте очевидними є і нові обставини й фактори ситуації у міжнародних відносинах постбіполярної доби, особливості еволюції державного ладу РФ на зламі ХХ–ХХІ ст., зокрема напівкримінальний характер політичного режиму сучасної Росії, що не може не впливати на зміст і спрямованість її зовнішньої політики, в т. ч. намагання не просто захопити і розграбувати інші країни, але й знищити їх державність і культуру.
Percursos autobiográficos de professores(as) que ensinam matemática e o movimento de (re)configuração da Identidade Profissional em um grupo de estudos
Authors: Nogueira Lemerton Matos , Carvalho José Ivanildo Felisberto de
Published: July 2023

Buscamos compreender neste trabalho o que as narrativas sobre os percursos de vida-formação-profissão de professores(as) que ensinam matemática revelaram a respeito do movimento de (re)configuração de suas Identidades Profissionais (IP), no contexto de um grupo de estudos. A partir de um olhar compreensivo-interpretativo sobre as narrativas de 6 desses professores, 4 unidades temáticas emergiram: a escolha pela docência em Matemática; o processo de formação inicial; a inserção profissional; e as perspectivas de futuro. Essas categorias produziram importantes significados sobre suas IP ‒ relacionados às condições socioprofissionais que os caracterizam ‒, sobretudo, porque eles (des)construíram crenças, se autoconheceram, agenciaram emoções, vulnerabilidades e compromissos profissionais.

Authors: Ratnasari Anggraeni , Sugiyanto Catur
Published: July 2023

This study examines the role of farmer wives in managing circular economy-based dairy farms and its impact on family income. The research focuses on the utilization of dairy waste through the production of organic fertilizer (manure) and biogas. The processed manure is used for fertilizing fodder crops and vegetables, both for personal consumption and sale. The study was conducted among farmers in the Tegalombo District of Pacitan, East Java. Regression analysis is employed to assess the factors influencing farmers' income and determine the potential of women's participation in farming to enhance household income. Based on a survey of 101 families, the findings reveal that households can save up to 145,949.35 rupiahs per month by reducing expenses on animal feed (grass). The regression results indicate that the adoption of circular economy practices positively impacts farmers' income, including income derived from dairy farming and overall farming activities. Moreover, by promoting the involvement of women in farm management, the study aligns with the second Sustainable Development Goal (SDG) to address hunger, achieve food security, and promote sustainable agriculture, as well as the fifth SDG to attain gender equality and empower women and girls.
Novel High-Precision and Efficient Momentum Source Method
Authors: Cao Tianshi , Bai Junqiang , Feng Shaodong , Qiu Yasong , Han Kai
Published: July 2023

Effective and reliable slipstream numerical simulation methods are important for propeller-driven aircraft design. This paper presents a high-precision and efficient momentum source method (HPE-MSM) based on a novel actuator disk load prediction model established by the frozen rotor method and blade element momentum theory. The simulation results of two benchmark test cases of an isolated propeller and a typical turboprop airliner show that the accuracy of the HPE-MSM proposed in this paper is close to the time-averaged unsteady results of the sliding mesh method (SMM), with a maximum error of 5% in aircraft lift and drag coefficients compared with experimental values. Meanwhile, the calculation efficiency of the HPE-MSM is comparable to quasi-steady methods, with only about 3.4% of the computation resources of the SMM in the whole aircraft simulation. This novel approach achieves high-precision and efficient simulation of the slipstream, which has the potential to improve the design level of propeller-driven aircraft.

Empowering women in the context of agricultural sustainability is an important and relevant issue. However, there are challenges and obstacles that need to be addressed in efforts to empower women farmers. Therefore, an in-depth analysis of the roles, challenges, and potentials of coconut farmer's wives in women's empowerment is necessary. The aim of this research is to evaluate the roles of coconut farmer's wives based on their potentials and the challenges they face, with the goal of supporting the sustainability of coconut farming. A Strengths, Weaknesses, Opportunities, and Threats (SWOT) framework combined with an Analytical Hierarchy Process (AHP) framework is used to analyze the perceptions of experts regarding the roles of coconut farmer's wives in the research location. The research findings indicate that the most prominent threat to the role of women farmers is the frequent changes in agricultural policies that can affect prices and the lack of training programs for women coconut farmers. Meanwhile, the prominent weaknesses affecting the role of women coconut farmers in the research location are the frequent limitations in accessing productive resources such as capital, land, technology, and training. The results obtained from this research can provide knowledge and understanding to various stakeholders regarding the most crucial issues to consider in formulating policies to enhance the role of women farmers
A CRITICAL ANALYSIS OF GENERAL THEORIES OF SYSTEMS
Authors: GRIBKOV ANDREY
Published: July 2023

The article deals with the question of why general theories of systems have not taken their proper place in the process of studying and creating the world. To answer this question, the author proposes to evaluate the compliance of existing general theories of systems to a set of basic requirements, which should be met by a reliable and functional general theory of systems: universality, generality, completeness, reliability, non-triviality, certainty of connections with private theories of systems, instrumentality and formalisation. The analysis revealed inconsistency or incomplete compliance of existing general theories of systems to the specified basic requirements. The basis for the creation of a general theory of systems, satisfying all of these basic requirements, according to the author, will be a change in the vector of knowledge underlying the general theory of systems. Supplementing exclusively epistemological methods of cognition with ontological ones, starting from a priori knowledge, will make it possible to build a more orderly and simple general theory of systems.

Published: July 2023

The vocal repertoire is considered in the article not only from the standpoint of effective educational and methodological material, but also as a focus of the world musical culture. In addition to solving the technological problems of vocal performance, it is also relevant how a vocal student expresses the artistic connotation of the work, its emotional Прикладные исследования, технологии 111 image, historical and stylistic features, genre characteristics, national attributes. The author of the article briefly formulates philosophical and methodological justification (the ancient Chinese treatise “Huainanzi”, Guillaume de Machaut, R. Ingarden, H.-G. Gadamer) of the importance of the spiritual and creative component of mastering the vocal repertoire as an integration of the “semantic horizons” of a vocal student and the author of the musical work. A finely tuned repertoire strategy in the vocal class generates such important professional and personal qualities of students as emotional resonance, artistry, imagination, the ability to associate, reflection, critical thinking, expert assessment, individual performance style, the art of transformation, communication skills.

Adsorption, using chemically modified zeolites, is a common conventional method of mitigating heavy metal pollution. However, the physical modification of zeolites with reducing agents subject to static magnets and biological trappers is yet to be explored. In this laboratory-based work, we partly gel-coated raw ZSM-5 pellets with zinc coarse powder and tested their performance in copper extraction from a polluted medium with copper sulfate. We also examined the performance subject to the presence of a neodymium magnet, with and without faba bean, Vicia faba, as a copper bio-trap. Additionally, on a limited scale, we plasma-sputtered ZSM-5 pellets with zinc and tested their copper extraction under the magnet effect. Inductively coupled plasma mass spectrometry (ICP) revealed that the reinforced zeolite led to the fastest copper extraction, outperforming the raw zeolite and the bio-trap, especially as time advanced. Accompanying the reinforced zeolite with the bio-trap was the most effective over time, followed by having both the magnet and the bio-trap to accompany the reinforced zeolite. However, interestingly, having the magnet as a sole companion of the reinforced zeolite was always better than using raw zeolite, but slightly of a lesser yield than having the reinforced companionless. The bio-trap was a better companion than the magnet, but after 20min having both companions was more beneficial than having the magnet alone and less yielding than having the bio-trap solo in the long term, indicating a synergistic effect between the reinforced zeolite and the bio-trap. Brunauer, Emmett and Teller (BET), Energy-Dispersive X-ray Spectroscopy (EDAX), and X-ray diffraction analyses, provided supportive information that underscored the stability yet the differential performance of ZSM-5. Although the extraction efficacy deteriorated sharply over time, the zinc-sputtered zeolite showed promising early results, exceeding those of the raw and the reinforced zeolites when the magnet was absent and almost identical to the outcome when the magnet accompanied the reinforced zeolite. Our amalgamative approach provides user-friendly novel methods of notable copper extraction, with high applicability potential for the extraction of other heavy metals from aquatic media.
Maximizing single-pass conversion does not result in practical readiness for CO2 reduction electrolyzers
Authors: da Cunha Shashwati , Resasco Joaquin
Published: July 2023

To integrate electrochemical CO2 reduction into the chemicals industry at scale, the outlet streams from CO2 electrolyzers must be product rich. Single-pass conversion is becoming increasingly common as a performance benchmark for CO2 electrolyzers because it suggests concentrated products and reduced separation energy for many catalytic processes. However, our analysis shows that CO2R reactor configurations that maximize single-pass conversion currently suffer from low product concentration in the outlet stream. This is because they restrict CO2 flow or operate in acidic cathode environments, which promote considerable hydrogen evolution as a side reaction. For any gas products besides syngas, high single-pass conversion does not signify that separation energy losses have been eliminated, or that product streams are directly suitable as feedstocks for downstream processes. We therefore recommend that researchers targeting CO2R scaleup report product concentrations rather than relying on single-pass conversion as an indicator of overall performance. Maximizing product concentration is a more meaningful target than maximizing single-pass conversion.

Retinoic acid receptor-related orphan receptor γ (RORγ) is a circadian regulator and has emerged as experimental therapeutic target in inflammation and immunity. The cyclic temporal role of RORγ in circadian rhythms makes temporally-resolved pharmacological control of this receptor particularly intriguing. To achieve next-generation tools to study RORγ biology, we designed RORγ ligands featuring a central azobenzene photoswitch, that act as light-dependent inverse agonists. Structural optimization enabled efficient photocontrol over RORγ inhibition, with remarkable potency on RORγ and excellent selectivity over related receptors. These high-specificity photopharmaceuticals can serve as high-precision tools to study the dynamic modulation of RORγ in signaling pathways and in inflammatory disorders.
Phase space perspective on a model for isomerization in an optical cavity

Explanation for the modification of rates and mechanism of reactions carried out in optical cavities still eludes us. Several studies indicate that the cavity-mediated changes in the nature of vibrational energy flow within a molecule may play a significant role. Here we study a model polaritonic system, proposed and analyzed earlier by Fischer, Anders, and Saalfrank[1], comprising of a one dimensional isomerization mode coupled to a single photon mode in a lossless cavity. We show that the isomerization probability in presence of virtual photons, for specific cavity-system coupling strengths and cavity frequencies, can exhibit suppression or enhancement for different choices of the initial reactant vibropolariton wavepacket. We observe qualitative agreement between the classical and quantum average isomerization probabilities in the virtual photon case. A significant part of the effects due to coupling to the cavity can be rationalized in terms of a “chaos-order-chaos” transition of the classical phase space and the phase space localization nature of the polariton states that dominantly participate in the quantum isomerization dynamics. On the other hand, for initial states with zero photons (i.e., a “dark cavity”) the isomerization probability is suppressed when the cavity frequency is tuned near to the fundamental frequency of the reactive mode. The classical-quantum correspondence in the zero photon case is unsatisfactory. In this simple model we find that the suppression or enhancement of isomerization arises due to the interplay between cavity-system energy flow dynamics and quantum tunnelling.
Examining the Influence of Desalinated Water on Iodine Concentration in Tap Water in Israel

Published: July 2023

Abstract Introduction: In Israel, desalinated water is a major source of drinking water. Previous studies have suggested that the levels of iodine in water provided by authorities may not accurately reflect the levels reaching end-users. Materials and Methods. We analyzed 21 tap water samples collected from different localities across Israel, 13 post-treated desalinated water samples from three of the largest Israeli desalination plants, and several natural water samples. An improved method of ICP-MS developed in our laboratory was used to analyze the content of iodine and other macro-elements, and determination of iodine was performed in alkaline media. Results: Our results showed that it is possible to distinguish between sample groups based on iodine concentration, water hardness, and Ca/Mg ratio. The median iodine concentrations for four groups of tap water samples ranged from 0.3 to 12.3 µg/L, which is lower than the concentrations previously reported by other researchers in Israel. Based on typical consumption, the water samples can provide no more than 3.39% of the recommended dietary allowance level for iodine. The analysis of post-treated desalinated water samples indicated that these waters comply with industrial specifications but contain only trace concentrations of iodine and much less magnesium than recommended by different public health authorities for public consumption of drinking water. Conclusion: The total iodine concentrations found were lower than several observations reported in previous years in the literature. There are currently no strict regulations regarding iodine and magnesium levels in drinking and/or softened (desalinated) water, but the intensive desalination plant application is already exhibiting a negative impact on public health. Further investigations are needed, but the present study provides useful insights for developing an effective policy to ensure adequate iodine supply for the population of Israel through drinking water.
Carbon Footprint of Artificial Intelligence in Materials Science: Should We Be Concerned?
Authors: Korolev Vadim , Mitrofanov Artem
Published: July 2023

While artificial intelligence is promoting remarkable progress in natural sciences, its broader societal implications are mostly disregarded. In this study, we evaluate the environmental impacts of deep learning in materials science through extensive benchmarking. Specifically, a diverse set of neural networks is trained for a particular supervised learning task to assess greenhouse gas (GHG) emissions during training and inference phases. A chronological perspective shows diminishing returns, which are expressed in a 28% decrease in mean absolute error and nearly a 15000% increase in carbon footprint of model training in 2016–2022. By utilizing up-to-date graphics processing units, it is possible to partially offset the immense growth in GHG emissions. Nonetheless, the practice to employ energy-efficient hardware is unaddressed by the materials informatics community, as it follows from the literature analysis in the field. Based on our findings, we encourage researchers to report GHG emissions on par with standard performance metrics.
