RETFAL: Real-Time Feedback System in Active Learning
Authors: Alnahidh Mohammed A. , Li Alice S. , Soh Ben , AlZain Mohammed A.
Published: January 2023

There are numerous difficulties and challenges faced by teachers in getting real-time feedback from students during lectures in active learning. Three different educational technologies will be investigated in this paper regarding their efficiency and cost effectiveness: (1) Wireless Systems; (2) Tablet Systems; and (3) Audio-Visual Systems. To that end, we propose a new system called Real-Time Feedback in Active Learning system (RETFAL), which is a phone-based application with a view to assist educators in getting real-time feedback.  The RETFAL system is implemented on the Android Studio platform using the Java programming language.  We validate our RETFAL system using usability testing via an online survey and a face-to-face survey. Finally, we do a comparative study involving the RETFAL system and the LearnStar system in terms of effectiveness and performance. We find that our proposed RETFAL system performs better than the LearnStar system in terms of efficiency and cost-effectiveness with regard to real-time feedback. With RETFAL, we anticipate the performance of students can be improved with effective real-time feedback in active learning.

Published: January 2023

One of the commodities of freshwater fish species that live in swamps and rivers that have high economic value is snakehead fish. In addition to having economic value, it also has a high albumin content and has various functions for health so it is very useful in the medical and industrial world. Snakehead fish is very rich in albumin, which is an important type of protein. There is 60% protein in plasma found in albumin, albumin in the blood functions to increase endurance, and is able to regulate the water balance in cells, waste products can also be removed, in the formation of new cells nutrients can be given so as to accelerate the recovery of body tissue that is split. post operation. The thing that must be considered at the time of feeding is the right amount, time and use. Therefore, the types of natural food that can be used as snakehead fish feed are silk worms (Tubifex sp), water fleas (Daphnia), small freshwater fish (gobies/tilapia). In this study, the design used was a non-factorial completely randomized design (CRD) with three treatments and three replications. From the results of the study, the highest growth of snakehead fish (Channa striata) was found in treatment A, namely absolute weight 6.61 grams, and average The average absolute length growth is 3.13 cm. The highest survival rate was in treatment A, which was 100% and the lowest was in treatment C, which was 76.6667%

Land insects function in the soil fertility process, assist the soil decomposition, and to accelerate soil material cycle so as there are equilibrum on food chains  and food webs cycle. The study aimed to examine of land insects in the South Sulawesi Regional Polda plantation and their surrounding environment benefits. The sampling technique was purposive sampling with an exploratory method, namely direct observation or observation in the field using the Pitffal Trap method at 5 stations. The study results at the South Sulawesi Regional Polda plantation obtained 172 individuals of soil insects consisting of 14 genera in 13 families. The land insects of Carabidae and Gryllidae families are insect genus with high abundance, while the families of Pentatomidae, Alydidae, Syrphidae, Saturniidae, Stratiomyidae, Blattidae, and Gryllotalpidae families has low abundances. The causing land insects genera high abundance at several research stations are the presence of supportive environmental conditions, where the habitats of some of these land insects are still preserved or natural, abundant food sources, and locations far from residential areas. The land insects found act as pollinators, decomposers, predators, parasitoids and bioindicators.
EFEKTIVITAS PEMBELAJARAN BAHASA INDONESIA DALAM SISTEM DARING KELAS IV UPT SDN 24 GRESIK
Authors: Alfisila Agam , Masub Bakhtiar Afakhrul
Published: January 2023

Learning effectiveness is a measure of the success of a process of interaction between students and between students and teachers in educational situations to achieve learning objectives. The development of children's learning will greatly depend on whether the process of teaching and learning activities (KBM) delivered by the teacher is good or not. The development of children's learning at home during the Covid-19 pandemic will tend to be different from the development of learning at school so that the teacher as a facilitator must have various innovations, to provide motivation to students in carrying out teaching and learning activities (KBM). The type of research that the authors use is a qualitative approach which uses descriptive analysis through field research with the aim of describing the effectiveness and barriers to learning Indonesian in the online system for class IV. The results showed that the implementation of learning Indonesian with an online system in class IV was less effective because in practice students were only given questions and only occasionally practiced, and the teacher did not know whether students really understood or not. Bearing in mind that students while studying at home are accompanied by parents or guardians of students, so it is possible that student assignments are assisted by parents or guardians of students. There are several obstacles that occur in online learning, namely teachers cannot know the extent to which students' abilities are, and also parents' finances differ in providing learningtools

Authors: Jesus Rossely Valoni de , Minoru Torisu Edmilson
Published: January 2023

Partindo da pergunta: Matemática, que tensão é essa?, este artigo sintetiza um estudo cujo objetivo foi desvelar as representações sociais da Matemática e compreender como um grupo de estudantes da primeira série do Ensino Médio de um Instituto Federal Mineiro se relaciona com essa disciplina. Buscamos apoio na Teoria das Representações Sociais de Serge Moscovici, complementada por Denise Jodelet e utilizamos questionário e entrevistas para obter informações sobre suas experiências, crenças, intuições e sentimentos com a Matemática ao longo da vida escolar. Os resultados indicaram que dependendo das tensões vivenciadas por essa disciplina, os estudantes a representam de formas diversificadas. Percebemos a importância dessas representações como algo que os afeta na sua forma de pensar, sentir e agir. Eles podem gostar ou não, sentir medo ou não diante dessa disciplina, dispensar maior ou menor dedicação aos estudos, como consequência das representações sociais que têm da Matemática.
O professor que desenvolve Modelagem Matemática: uma compreensão filosófica e epistemológica
Authors: Fritsch Cararo Elhane de Fatima , Klüber Tiago Emanuel
Published: January 2023

Este artigo interroga quem é o professor, em sentido filosófico-epistemológico, que desenvolve Modelagem Matemática na Educação Matemática. Ao contrário do que se possa pensar, não buscamos por perfis específicos, superficiais, mas investigar a fundo, os aspectos que constituam o pronome quem, o qual remete, numa acepção primária, à que pessoa. Assim, discutir esses aspectos requer admitir algumas dimensões de sua constituição como o contexto formativo, profissional, sociocultural, histórico e epistemológico deste que desenvolve Modelagem Matemática na Educação Matemática. Aquilo que é por nós interrogado, pode assim ser redigido: Quem é este “quem” que desenvolve Modelagem Matemática na Educação Matemática? Aqui, especificamente, buscamos refletir sobre as diferentes dimensões filosóficas envolvidas, na escolha da pessoa que desenvolve Modelagem. Para tanto, perquirimos leituras que lançam luzes sobre os diferentes modos de compreender este “quem” e seus diferentes modos de se mostrar. As principais variantes discutidas neste artigo esclarecem a possibilidade de ver o professor como sujeito, indivíduo, pessoa e cidadão. Desta abertura, podemos afirmar que a argumentação aqui realizada fomentará discussões na formação inicial e continuada de professores de Matemática e poderá contribuir para a compreensão de aspectos relevantes na elaboração de propostas, modelos e/ou programas de formação do professor de Matemática.
Contributos filosóficos de Nancy Fraser para estudos e pesquisas em Educação Matemática: feminismo, justiça e capitalismo
Authors: Taveira Flavio Augusto Leite , Peralta Deise Aparecida
Published: January 2023

Este texto explora algumas discussões presentes nas elaborações teóricas de Nancy Fraser, vislumbrando possibilidades teórico-filosóficas para estudos e pesquisas em Educação Matemática, focalizando três temáticas de grande relevância para a autora: Feminismo, Justiça Social e Capitalismo. Discorremos sobre cada uma destas temáticas, começando com o diagnóstico do embate entre feministas pela igualdade e feministas pela diferença, considerando as injustiças de gênero. A preocupação com as questões de Justiça Social é abordada a partir da necessidade de alinhamento das lutas de redistribuição às lutas de reconhecimento. As críticas de Fraser ao capitalismo são apresentadas via análise da cooptação das pautas por reconhecimento pelas políticas neoliberais. Por fim, apresentamos um quadro de educações matemáticas pela diferença e educações matemáticas pela igualdade, articulando-o à conjugação de redistribuição e reconhecimento nas lutas contra as injustiças sociais no movimento da Educação Matemática.
A face extralógica do Último Teorema de Fermat: um ensaio sobre a filosofia da prática matemática
Authors: Monteiro dos Santos Arilson , Carvalho Henrique Marins de
Published: January 2023

A Filosofia da Matemática durante muito tempo dedicou-se a aspectos ontológicos e epistemológicos para explicar os objetos da Matemática, área do conhecimento que costuma ser, tanto no ambiente escolar como no cotidiano, entendida como um reduto de conceitos universalmente e eternamente verdadeiros, cuja certeza é garantida pela estrutura lógica do sistema formal a partir do qual é construída e representada. Desde o século passado, no entanto, aspectos da prática matemática como a intuição, a criatividade e o recurso a representações que ultrapassam a simbologia normativa são objeto de estudo da Filosofia da Prática Matemática, que compreende a matemática como um produto da ação humana e, dessa forma, dependente de questões sociais, culturais e psicológicas, tanto em âmbito coletivo como particular. A partir de pesquisa bibliográfica apoiada em autores que se dedicam contemporaneamente a essa temática, são apresentadas considerações sobre os aspectos extralógicos no processo individual do matemático britânico Andrew Wiles que culminou na escrita formal e rigorosa da demonstração do Último Teorema de Fermat – importante proposição do estudo de números e equações algébricas – realizada 358 anos após sua formulação, reconhecendo que nenhuma demonstração de teoremas matemáticos e, em especial essa produção estudada, pode ser entendida apenas pela análise restrita da argumentação dedutiva e do formalismo simbólico.

Apontamentos para o ensino da matemática escolar sob inspiração wittgensteiniana
Authors: Gottschalk Cristiane Maria Cornelia
Published: January 2023

O texto reúne algumas reflexões sobre a natureza da matemática e seu ensino no contexto escolar, ancoradas nos resultados terapêuticos obtidos na segunda fase do pensamento do filósofo Ludwig Wittgenstein sobre os fundamentos da matemática. Dentre eles, a ideia de autonomia das proposições matemáticas em relação ao empírico que resulta de sua crítica ao modelo referencial da linguagem presente nas concepções realistas e idealistas da matemática, relativizando-se, assim, crenças dogmáticas sobre a natureza de seus conteúdos, com implicações imediatas para as práticas pedagógicas. Tem-se como hipótese central, que ao ser explicitada a função normativa (e não descritiva) dos enunciados matemáticos, vários equívocos e confusões podem ser evitadas no ensino da disciplina, que ocorrem, em boa parte das vezes, quando se introduz métodos característicos das ciências naturais que levariam supostamente à descoberta de conteúdos matemáticos em geral. Observa-se que, ao se desconsiderar o papel distinto desempenhado pelas proposições matemáticas em relação ao das proposições empíricas, passa-se a se acreditar que as conjecturas matemáticas seriam hipóteses a serem testadas através de experimentações empíricas, relegando-se as provas matemáticas a segundo plano, ou mesmo descartando-as, como se a formalidade da matemática fosse um empecilho para a sua aprendizagem no contexto escolar. Em contraposição a esta crença, propõe-se na formação dos professores a explicitação da função paradigmática das demonstrações formais, que não só produzem novos sentidos, como também instruem o aluno a empregar os teoremas que fazem parte do currículo escolar. Conclui-se o texto propondo-se diretrizes preventivas de confusões na sala de aula advindas de pedagogias permeadas por concepções filosóficas sobre os fundamentos da matemática que, por sua vez, estão atreladas a uma concepção referencial da linguagem matemática.
Uma possibilidade de uma educação (meta)matemática trabalhando com o teorema da incompletude de Gödel
Authors: Batistela Rosemeire de Fatima , Viggiani Bicudo Maria Aparecida
Published: January 2023

O objetivo deste artigo é expor compreensões e possibilidades de trabalhar com professores em forma/ação durante o curso de graduação em licenciatura em Matemática, enlaçando-os em discussões que foquem temas importantes da Matemática, da Educação Escolar, da complexidade da Educação e da Educação Matemática.  Assumimos que a abordagem de questões filosóficas pertinentes à Matemática e à conduta dos professores de Matemática são vitais para a forma/ação dos estudantes de cursos de licenciatura em Matemática. Afirmamos que é preciso que os estudantes se deem conta do que falam, quando falam de Matemática e de produtos matemáticos, bem como possam compreender o que significa transpor o conhecimento matemático, com seus valores de certeza e de exatidão, implícitos à produção desse conhecimento, para outras realidades não matemáticas, como as econômicas, políticas e sociais.  Para explicitar nossas argumentações tomamos como material a ser entendido e questionado o teorema da incompletude de Gödel, focando-o como um exemplo de realizar a possibilidade de uma educação metamatemática, em cursos de forma/ação de professores de Matemática, focando as perguntas acima mencionadas.
“A Matemática está em tudo”? Problematizando uma razão-mundo e uma razão do mundo
Authors: Gondim Diego de Matos
Published: January 2023

Este ensaio busca problematizar a expressão “A Matemática está em tudo!”, utilizada como tema da 14º Edição da Semana Nacional de Ciência e Tecnologia, evidenciando-a como um questionamento que atravessa toda sua escrita. Para tanto, o texto é constituído por dois atos, quais sejam: a dona da festa; e meu salão é maior que o mundo. O primeiro, objetiva evidenciar a constituição da Matemática enquanto substantivo, razão de si e dos outros. Para tanto, utiliza-se a análise foucaultiana a respeito da constituição de uma formação discursiva em saber. O segundo, busca problematizar essa constituição como uma razão-mundo e razão do mundo, afirmando a efetuação de uma captura dos processos de subjetivação como forma de atualização de seu poder. Com estes dois atos, desenvolve-se a consideração de que a Matemática se estabelece como uma racionalidade, constituindo-se em uma forma de governamentalidade das subjetividades na sociedade contemporânea. Como considerações finais, o questionamento “quem somos nós”, levantado por Michel Foucault no século passado, se apresenta como uma estratégia ética e política que buscar se desfazer dessa racionalidade e deste vínculo individualizante.
Justiça por vir: por uma Educação Matemática para adiar o Fim do Mundo
Authors: Tamayo Carolina , Giraldo Victor
Published: January 2023

Assumindo como lugar de partida a filosofia de vida do “Buen Vivir” dos povos dos Andes, este artigo tem como objetivo apresentar diversas reflexões produto de pesquisas que procuram por justiça epistêmica e social ao tensionar discursos e práticas curriculares que promovem uma imagem única de Matemática que invisibiliza e subalterniza saberes e corpos. Para isto, apresentamos uma cena dialógica com duas personagens, que falam a partir de afetos que nos atravessam, mas não são inteiramente nós; não falam a partir de vozes individuais, mas sim com base em diferentes trabalhos desenvolvidos de forma coletiva e dialógica entre os integrantes de dois grupos de pesquisa de Educação Matemática brasileiros. No embate levantado sobre Matemática a sua universalidade e os seus vínculos com a modernidade/colonialidade, reivindicamos uma Educação Matemática para adiar o fim do mundo – ou então, uma Educação Matemática para adiantar o fim deste mundo, desta abstração de humanidade, uma Educação Matemática que se posicione contra a proclamada “volta ao normal”, uma Educação Matemática para produzir outros mundos, para contar outras histórias desses mundos.
Neoliberal Mathematics Education Research in the Service of Big Capital
Authors: D'Souza Rossi
Published: January 2023

Neste artigo, argumento que a Pesquisa em Educação Matemática (PEM) internacional é ditada pelos interesses e pela agenda dos países imperialistas, que des-historiciza as condições materiais das nações imperializadas e empobrecidas, ao mesmo tempo em que ofuscam deliberadamente as razões econômicas subjacentes ao “fracasso” do aprendizado da matemática resultados de seus alunos. Em vez disso, sob o pretexto de melhorar o ensino/aprendizagem da matemática, tais pesquisas costumam culpar as próprias pessoas desses países imperializados pelos 'baixos resultados de aprendizagem' de seus alunos, atribuindo-os a crenças, mentalidades, práticas “culturais” e “locais”, etc., produzindo assim justificativas acadêmicas para a destruição neoliberal de seus sistemas públicos de educação. Começo meu argumento baseando-me em meu estudo de pesquisa de doutorado com alunos de matemática com deficiência visual de comunidades marginalizadas socioeconomicamente na Índia. Em seguida, apresento uma breve visão geral de alguns trabalhos de pesquisa em educação matemática no contexto dos países da África Subsaariana para ilustrar meu ponto.

What’s Wrong with Lyotard Paradigm? The Repudiation of Generalization and The Diversity of Research Area in Accounting
Authors: Cahyono Suham , Sawarjuwono Tjiptohadi
Published: January 2023

Purposes - This study aims to investigate the Lyotard paradigm that dominates the framework of research in accounting and finance, especially the concept of generalizing the results of studies that apply a quantitative approach.

Research Method - This study is a literature study that uses secondary data from various articles, journals, library books and also Scopus journal articles to provide a lot of evidence related discussion topic. We obtained data for nearly 40 articles from a database of reputable national and international journals indexed by Scopus and Google scholar.

Findings - The results of this study show that many scholars alignment with lyotard perspective has been refuted by several axioms and new paradigms that have developed in the midst of the turmoil of research in accounting and finance, so that this has led to various rejections and expansion of studies in accounting and finance, especially studies that use a critical research approach. and postmodernism

Implications - The main contribution of this study is to provide a wider literature on research perspectives in accounting and finance, especially for researchers who want an approach that applies an expanded study result. The limitation of this research is that it only considers Lyotard's approach to the generalization paradigm in addition to other approaches such as Derrida and Machiavellianism.

„Zapojíte se do diskuze?“ Uvažování o muzeích na stránkách českých muzejních periodik (1989–2021)
Authors: Kurz Michal
Published: January 2023

The analysis based on the leading Czech museum periodicals from 1989–2021 explores the understanding of the phenomenon of the museum. The conclusions show the lack of advanced discussion about the museum’s role during this period. Most museum workers are only concerned with practical problems; they are unwilling to reflect on their work critically, and their idea of the museum is based primarily on physical collections. There is an evident distance between the narrow circle of active theorists in the academic environment and the reserved majority of curators and conservators in the regional museums. This majority does not participate in public discussions, and because of that, its opinions and arguments are more implicit in the analyzed texts. Many published articles are concerned with the history of concrete museum collections, buildings, and significant personalities. The authors frequently underlined the long and rich tradition of Czech museums. However, their perspective lacks a necessary reflective examination (i. e. the museum as an institution and a building with a long history but without a precisely defined position in contemporary society). Review of new exhibitions is a long-neglected genre, often replaced with abstracts or notices. During the last few years, the situation has been improving due to some impulses of new museology and educational turn (i. e. the museum as a responsive and accessible institution to the local community).

The effect of staircase stopping accuracy and testing environment on stop-signal reaction time
Authors: Tran Dominic M. D. , Chowdhury Nahian S. , Harris Justin A. , Livesey Evan J.
Published: January 2023

Abstract

The stop-signal task is widely used in experimental psychology and cognitive neuroscience research, as well as neuropsychological and clinical practice for assessing response inhibition. The task requires participants to make speeded responses on a majority of trials, but to inhibit responses when a stop signal appears after the imperative cue. The stop-signal delay after the onset of the imperative cue determines how difficult it is to cancel an initiated action. The delay is typically staircased to maintain a 50% stopping accuracy for an estimation of stopping speed to be calculated. However, the validity of this estimation is compromised when participants engage in strategic slowing, motivated by a desire to avoid stopping failures. We hypothesized that maintaining stopping accuracy at 66.67% reduces this bias, and that slowing may also be impacted by the level of experimenter supervision. We found that compared with 50%, using a 66.67% stopping accuracy staircase produced slower stop-signal reaction time estimations (≈7 ms), but resulted in fewer strategic slowing exclusions. Additionally, both staircase procedures had similar within-experiment test–retest reliability. We also found that while individual and group testing in a laboratory setting produced similar estimations of stopping speed, participants tested online produced slower estimates. Our findings indicate that maintaining stopping accuracy at 66.67% is a reliable method for estimating stopping speed and can have benefits over the standard 50% staircase procedure. Further, our results show that care should be taken when comparing between experiments using different staircases or conducted in different testing environments.
ORCA: A picture database of object–scene arrangements for cross-cultural and aging research

Published: January 2023

In recent years, cross-cultural research on the modulation of basic cognitive processes by culture has intensified – also from an aging perspective. Despite this increased research interest, only a few cross-culturally normed non-verbal stimulus sets are available to support cross-cultural cognitive research in younger and older adults. Here we present the ORCA (Official Rating of Complex Arrangements) picture database, which includes a total of 720 object–scene compositions sorted into 180 quadruples (e.g., two different helmets placed in two different deserts). Each quadruple contains visually and semantically matched pairs of objects and pairs of scenes with varying degrees of semantic fit between objects and scenes. A total of 95 younger and older German and Chinese adults rated every object–scene pair on object familiarity and semantic fit between object and scene. While the ratings were significantly correlated between cultures and age groups, small but significant culture and age differences emerged. Object familiarity was higher for older adults than younger adults and for German participants than for Chinese participants. Semantic fit was rated lower by German older adults and Chinese younger adults as compared to German younger adults and Chinese older adults. Due to the large number of stimuli, our database is particularly well suited for cognitive and neuroscientific research on cross-cultural and age-related differences in perception, attention, and memory.
Las OMICAS y la tuberculosis en el Perú: su impacto en el curso, diagnóstico y tratamiento
Authors: Guio Heinner
Published: January 2023

Después de la publicación de los datos del genoma humano (1) se han generado diferentes líneas de investigación que van desde el desarrollo de la biología, la biotecnología, el desarrollo de fármacos e incluso implicancias históricas para entender los mecanismos de evolución y migración de los seres humanos a nivel del planeta. La tuberculosis es considerada una de las primeras enfermedades humanas de las que se tiene evidencia, con una antigüedad aproximada/calculada de entre 10 000 y 15 000 años, la cual es causada por el agente patógeno Mycobacterium tuberculosis. En nuestro país los determinantes sociales no permiten un diagnóstico oportuno, demorándose hasta 57 días después de la aparición de síntomas, tiempo en el cual el paciente sigue contaminando a su entorno (2). El secuenciamiento completo de genomas de M. tuberculosis con diferentes grados de resistencia a las drogas de primera (3) y segunda línea (4) ha permitido discriminar mejor los fenotipos para un mejor abordaje epidemiológico (5) y encontrar nuevos SNPs (Single Nucleotide Polymorphisms) que en nuestro contexto epidemiológico podrían conferir resistencia bacteriana en las micobacterias circulantes en la población peruana. Estos nuevos SNPs debieran ser considerados en los nuevos métodos moleculares que ingresan a nuestro país para un diagnóstico más preciso basado en el perfil genético de las cepas circulantes.

The electronic industry is one of the most dynamically developing industries in the global economy and has a significant impact on the pace of development of related industries and the level of technological independence of states. Various types of external trade and economic sanctions imposed by Western countries and the strengthening of the import substitution policy in the Russian economy require a revision of the vectors for the development of electronic industry enterprises. The withdrawal of some foreign companies from the Russian sales market at the same time makes it possible to increase demand for domestic products and increases the requirements for the development and production of electronics in Russia. The analysis of scientific works shows that at the present stage of production development, non-technological innovations, including organizational and managerial ones, are an important component of increasing the competitiveness of industrial high-tech enterprises. The purpose of the study: to determine the level of development of organizational and managerial innovations in the Russian electronics industry. The implementation of this goal required the solution of the following tasks: to define the concept of organizational and managerial innovations in accordance with modern standards, to determine the degree of development of the topic of organizational and managerial innovations in electronics industry enterprises in Russian publications, to compare the levels of implementation of organizational and managerial innovations in the electronics industry and other domestic industries. This paper analyzes the level of implementation of organizational and managerial innovations in the Russian electronics industry. According to the modern 4th edition of the Oslo manual (international standard in the field of innovation statistics), the definition of the concept of organizational and managerial innovations is given. On the basis of statistical data, the level of development of this type of innovation in relation to product and process innovations was determined, and a comparison was made with respect to high-tech and all Russian organizations. Interest in the introduction of organizational and managerial innovations in the global industry has increased significantly in recent years, so understanding the current situation in the development of this type of innovation in the Russian electronics industry can contribute to the development of strategies for the development of this industry.

The relevance of the study is due to the need to study the limits of the permissibility of business behavior of companies in the conditions of economic turbulence that has developed under the influence of various macro and microfactors. The disruption of logistics chains against the background of the first sanctions restrictions, the introduction of protective duties, a comprehensive system of state support for the industry (the “trade-in” program for changing the car fleet) led to new structural and behavioral models of the functioning of markets, which required understanding and selection of an adequate policy of state regulation. The purpose of the study is to consider the strategy of behavior of the dominant player with a pronounced differentiation in pricing policy in relation to different counterparties in a scarce market on the example of an antimonopoly case against a dominant economic entity in the market of solid-rolled wheels with a diameter of 957 mm within the borders of the Russian Federation (2018–2019). The objectives of the study are to consider how the implementation of three important elements of the company’s marketing strategies – price formation, market segmentation based on the Buchanan product concept and the selection of counterparties, as well as methods and technologies of discount policy in conditions of unsatisfied demand, can affect the functioning of a scarce market and affect price growth for two years. In the context of this study, the transformation of the mechanism of price discrimination in scarce markets is presented. It is noted that the behavior of the dominant entity regarding the establishment of a monopolistically high price in a scarce market looks economically unconditioned, the establishment of a differentiated final price for the sale of goods to various buyers at a level higher than the prices of the period preceding the shortage indicates price discrimination of the first and second degree. The analysis of various types of discounts shows that sales promotion is not a necessary marketing tool, as it reduces the monopoly profit of the seller and does not contain motivation for the formation of competitive initiations. The main gain of the consumer is not the volume of potential discounts, but the speed of searching for goods, contracting on any terms, the promptness of concluding transactions and obtaining maximum financial gain in conditions of uncertainty.

El objetivo de esta investigación es realizar un diagnóstico respecto al nivel de conocimientos de educación financiera que tiene una muestra de 70 estudiantes de educación media superior en una localidad situada en la región Sur de México. Esta investigación es original porque evalúa este fenómeno en un contexto no analizado previamente, lo que resulta útil para el diseño de estrategias basadas en necesidades regionales. Además, esta investigación es cualitativa, se realizó investigación documental y se aplicó una encuesta descriptiva diseñada a partir de la metodología utilizada por la OCDE. Se encontró que el 64% de los estudiantes no sabe con claridad qué es la educación financiera y el 100% desconoce los intereses, comisiones o recargos que se deben pagar por utilizar una tarjeta de crédito, un préstamo o el crédito de una tienda departamental. El 60% sí comprende a qué se refiere la inflación y solamente el 48.5% tuvo respuestas correctas respecto al cálculo del interés, mientras que únicamente el 22% de los jóvenes ahorra de manera formal y el 54% se preocupa por ahorrar para acciones futuras. Además, 20% de estudiantes de esta región necesitan una cuenta de banco para recibir envíos de dinero de familiares migrantes.

Given the world's current situation with the COVID-19 pandemic, several businesses have recently encouraged remote working from home. A variety of benefits are provided by cloud computing, including simplified IT and management, secure Internet-based remote access from practically anywhere, and cost savings. As a result, more people use the cloud, but there are also increasing cyber-attacks on cloud networks. However, several companies and organizations, who do not know the security threats that Cloud systems pose, are still worried about using the cloud. Reports previously released by researchers from academia, business, and standard organizations proposed solutions to these problems. This paper examines state-of-the-art papers on topics, challenges to requirements, and identified security system vulnerabilities. In addition, we will review the different components and the security and privacy concerns of current cloud computing systems. Finally, we present a variety of security threats targeting and addressing cloud storage services. In particular, we raise awareness on security issues that cloud organizations including cloud service providers, data owners and cloud users face and address them.
