One is Not Born a Mathematician: In Conversation with Vasily Davydov
Authors: Fellus Osnat , Biton Yaniv
Published: August 2023

That mathematics education has been one of the central concerns of educational systems worldwide is no secret. It is also an established consensus that as far back as eighty years ago, Russian psychologists such as Vygotsky, Luria, Meshcheryakov, and Davydov have pioneered work that contributed to the understanding of teaching and learning and shifted the trajectory of schooling in the Western World. Looking back, we feel that there is more to this legacy that awaits to be further explained and extended to potentially address some of the pressing issues in mathematics education. To bring forth this legacy, the authors engage in an imaginary conversation with Vasily Davydov to tease out notions that include, inter alia, language and interaction, learning and teaching, and empirical and theoretical thinking. The utilisation of a conversation as a method of inquiry for the purpose of this paper was intentional as it not only encompasses the very method of teaching advocated by Davydov, thus conveying that the means is the message, but it is also conducive to the exploration of simultaneously surfacing ideas and phenomena. The questions asked, clarifications provided, and contradictions that still remain chart a map that displays theoretical vistas and empirical landscapes drawn and inspired by Davydov's legacy. Specifically, Fellus and Biton bring forth citations from Davydov's works that are used as signposts in the conversation that unfolds.

Authors: Shaqlaih Ali , Celik Mehmet
Published: August 2023

This study describes an intervention to address motivation and student engagement in upper - level math courses. The effect of the intervention regarding students' achievements is investigated via students' opinions and data analysis from students' assessments. The results of this study show that the featured intervention decreases anxiety, provides confidence, and increases motivation for class preparation which, in turn, fosters students' "in- and out-of- class interactions" and boosts students' self-confidence on studying math on their own'. Moreover, students' assessment scores reveal a significant increase on students' grades.
Flipping the learning of mathematics: Different enactments of mathematics instruction in secondary classrooms
Authors: Muir Tracey
Published: August 2023

The concept of flipping the classroom and flipped learning is becoming increasingly more popular in secondary schools. Although more prevalent in tertiary teaching, flipped learning has a number of affordances that may address the challenging demands of teaching secondary mathematics. While enactments of the approach vary, flipped learning requires a reconceptualization of traditional secondary mathematics instruction in that instructional content is assigned as homework before class, providing for more targeted in-class teaching. This paper reports on a study which investigated the enactment of the flipped classroom in ten different secondary mathematics classes. Findings indicated that there were essentially three different ways in which the approach was enacted, yet all enactments appeared to offer similar affordances. The study adds to the limited research which documents flipped learning in secondary mathematics classes and contributes to current understandings of teachers' and students' perceptions of their experiences of such an approach and the affordances it offers. The study has implications for secondary students and teachers of mathematics, particularly those who are teaching within the constraints of prescribed textbooks and externally imposed assessment measures.

Authors: Gulkilik Hilal , Kaplan Hatice Aydan , Kaplan Hatice Aydan , Emul Nida
Published: August 2023

The purpose of this qualitative study was to analyze the relationship between argumentation and proof in terms of verbal, visual, and algebraic representations of mathematical concepts. We conducted task-based interviews based on geometric locus problems with six undergraduate mathematics teachers while they were working in pairs. We identified the mathematical arguments that the pairs produced in argumentation and proving by using Toulmin's model. We examined the role of representations in the relationship between these two processes by performing an analysis considering the referential system and the structure dimensions. Data analysis revealed that students could transform the abductive and inductive arguments to deductive arguments in the process of proving if they could produce and utilize algebraic representations in the warrants and backings by relating visual and verbal representations.
Light-Duty Vehicles Electrification: Carbon Dioxide Reduction Impact
Potential and Considerations of Its Effect on Electricity Generation
System
Authors: Hébert Guillaume
Published: August 2023

In the context of the race toward minimum road transportation carbon dioxide
(CO2) emissions, the needs for tools comparing various powertrain
options are of the highest importance. Various authors have demonstrated the
necessity to take into account the full life cycle assessment (LCA), a
simplified tank-to-wheel calculation being unsatisfactory in providing guidance
regarding the optimized technological choices depending of variables
manufacturing and operating conditions.

There are several examples to be found in the literature but they have been found
to be very specific to most of their assumptions (e.g., vehicle models,
electricity carbon intensity for usage or production, etc.). This paper focuses
first on possibly to establish a more general model and relative graphic tool to
compare carbon foot print of various powertrains with incremental
electrification levels of light-duty vehicles (spark ignition engine, full
hybrid, plug-in hybrid, and battery electric vehicle), enabling to choose
relevant parameters for the production and the usage of the vehicles.

As expected, the level of electrification is identified as a key parameter of the
overall vehicle carbon footprint. However, electrifying the fleet represents a
major challenge for the electricity generation system and grid, requesting
detailed analysis. That’s the subject of the second part of the study, which
also proposes a graphic way of analyzing the situation. Examples are being
provided for European countries with different energy strategy (i.e., France and
Germany), including a tentative to consider the possibilities offered by vehicle
to grid (V2G) to overcome intermittency nature of ReNeWable energy sources (RNW)
such as PhotoVoltaic solar (PV) and wind turbines (WIND).

Published: August 2023

The role of the PD-1/PD-L signaling pathway in the regulation of the immune response is currently the focus of research. Numerous studies have shown the key role of PD-1 molecules in the regulation of autoimmune, antitumor and antiviral reactions. The culture of rat and mice lymphocytes, as well as animal experimental models of immunopathologies are widely used in research. However, rat lymphocytes are almost not used to study the PD-1/PD-L pathway. There is no data on PD-1 expression or methods of its induction on rat lymphocytes. In human T-lymphocyte culture, PD-1 expression can be induced by NIB1412 anti-CD3 antibodies coated in the well of culture plates. In this study, we investigated the effect of G4.18 anti-CD3 antibody on PD-1 expression in peripheral blood lymphocyte of intact Wistar rats in vitro. According to some literature data, G4.18 anti-CD3 antibodies in immobilized form can activate isolated rat T cells, and according to others, inhibit allogeneic reactions in mixed lymphocyte culture and block cytotoxicity of cells obtained from rats with a developed graft rejection reaction. We found that incubation of rat blood lymphocytes with G4.18 anti-CD3 antibodies immobilized on plastic leads to a change in cell morphology and induction of PD-1 on CD3+ lymphocytes. After incubation with anti-CD3 antibodies, the proportion of PD-1+ lymphocytes among CD3+ lymphocytes was 12.056.04%, which is significantly higher than the proportion of such cells before incubation and during incubation in a cultural medium, which amounted to 2.602.62% and 4.595.81%, respectively. In the dot-plot graphs showing the distribution of cells according to the parameters of forward scatter and side scatter, PD-1+CD3+ lymphocytes induced by anti-CD3 antibodies are localized in the region of relatively lower forward scatter and greater side scatter. Perhaps these cells belong to apoptotic cells.

Published: August 2023

In COVID-19, the clinical outcome depends on a wide range of factors, including genetic features. Among them, TLRs, the genes encoding the receptors of innate immune system are of particular interest since they play the key role in development of innate immune response. The present study concerns the newely identified allelic variants of the TLR-9 (-1237)*T/C gene in Russian residents from the Chelyabinsk Region who had COVID-19 complicated by the bilateral viral pneumonia. Polymorphic variants of TLR-9 (-1237)*T/ C were determined by polymerase chain reaction. It was found that, among the COVID-19 patients, a TLR-9 allele (-1237 C) with higher transcriptional activity was more common than in the control group (19.421% and 11.275%, respectively, p = 0.019), and its homozygous genotype TLR-9 (-1237)*C was not detected in the comparison group. TLR-9 allele (-1237)*T in the patients with COVID-19 was less common in comparison with the control group (80.579% and 88.725%, respectively, p = 0.019). Taking into account the differences in suggested TLR-9 expression in more severe COVID-19 patients, we compared distribution of TLR-9 (-1237)*T/ С allele polymorphism in the patients with different severity of COVID-19. In the group of patients with mild form, the TLR-9 (-1237)*T/T genotype was more common as compared with patients who had more severe clinical course. The differences were significant at the trend level when compared with patients with a medium-severity disease (86.364% and 66,000%, respectively; p = 0.076).
Role of passive and active myostimulation for the changing levels of some cytokines
Authors: Ahmetyanov Rustam R. , Davydovа Evgenia V. , Sabiryanov Artur R. , Shcherbakova Irina L.
Published: August 2023

Injury to the anterior cruciate ligament (ACL) of the knee joint is complicated by development of arthrogenic muscle inhibition due to disregulating afferent influences on the excitability of the spinal and supraspinal tracts. The aim of our work was to study electromyography parameters, and myokine levels in the course of myostimulation in traumatic ACL injury.

28 male athletes with traumatic ACL injuries participated in the study. On admission to the clinic, all patients underwent electromyographic examination of the injured limb by the means of Viking Quest EMG/ EP apparatus (Nicolet, USA). Some patients, 10 days before starting the surgical treatment, underwent passive electrical myostimulation (EMS) of the quadriceps femoris muscle using the INTELECT Advanced device (Chattanooga (DJO), USA). Further on, all patients underwent arthroplasty using a Karl Storz arthroscope (Germany). In the postoperative period, during immobilization for 2-weeks, the patients received EMS. After removing the orthosis, the patients switched to active training. The cytokine levels were studied using ELISA reagent kits from Vector-Best, Novosibirsk (IL-6), or from Cloud-Clone Corp. (China) for TGF1assays. Statistical processing of the material was carried out using the Statistica package. vers.10.0 (StatSoft Inc., USA).

The highest average amplitude (V) was recorded by electromyography in healthy individuals. In patients of the main group, significantly lower values of the average amplitude were recorded. After a 10-day EMS, a significant increase to the reference values of healthy individuals was noted. In the postsurgical dynamics, EMG indicators without EMS treatment remained at the same low levels. Meanwhile, the values following EMS treatment were comparable with those in healthy individuals, thus reflecting a faster and better muscle recovery after injury. The levels of IL-6 and TGF-1 cytokines (myokines) significantly exceeded the initial levels in the course of EMS. The biological significance of increased IL-6 levels during the muscle exercise may consist the activation of AMP kinase and/or phosphatidylinositol-3-kinase at the level of skeletal muscles thus providing more efficient supply of energy substrate to the muscles. TGF-1 promotes fibroblast proliferation, thus increasing collagen content.

Passive and active EMS leads to an improvement in electromyography parameters, along with increased concentration of myokines (IL-6 and TGF-1) in peripheral blood, thus promoting improvement of energy balance, increasing the anti-inflammatory and repair potential of the damaged tissues.
Effect of cucurbiturils on the numbers and differential counts of peripheral blood leukocytes in laboratory animals after in vivo parenteral administration

Published: August 2023

Immunological safety of nanoparticles is an urgent problem for development of drug delivery systems used as the basis for creating these systems. Cucurbit[n]urils (CB[n]) are molecular nanocontainers that can encapsulate various drugs and serve as the basis for delivery systems. Cucurbiturils are low-toxic compounds: under in vitro conditions, they exhibit weak immunomodulatory properties, without sufficient immunotoxicity. The aim of the present study was to evaluate the in vivo effects of cucurbiturils on the number and differential leukocyte counts in peripheral blood.
BALB/c mice aged 2-4 months were used in the work. For this study, cucurbiturils were diluted in phosphate-buffered saline and administered to laboratory animals intraperitoneally (three times a week).
When evaluating the effect of cucurbit[7]uril on blood parameters of the animals after three intraperitoneal injections weekly, no statistically significant changes were registered. However, at first administration, the animals showed a slight increase in relative number of lymphocytes after the first injection of CB[6], and an increased proportion of neutrophils after the first administration of CB[8]. Meanwhile, the proportions of lymphocytes and neutrophils were within normal ranges after the 2nd and 3rd injections of cucurbiturils, and did not show any significant differences against the controls. Moreover, the impact upon the subpopulation composition of peripheral blood lymphocytes in laboratory animals was assessed. After injection of CB[6], there was a decrease in T lymphocytes in the peripheral blood, along with increased proportion of CD19+B lymphocytes compared with the controls. CB[7] and CB[8] injections did not affect the subpopulation profile of peripheral blood lymphocytes.
We have found that intraperitoneal administration of CB[n] did not affect the blood parameters of laboratory animals, thus, probably suggesting the in vivo safety of these compounds. At the same time, CB[6] is able to exert a stimulating effect on humoral immunity by increasing relative contents of B lymphocytes.

Panel-Data Analysis of Capital Account Liberalization and Tax Revenue
Authors: Ilievski Bojan
Published: August 2023

Abstract

The main motive behind financial repression is fiscal. The government wishes to promote development but lacks the resources to do so. In fact, financial repression is an instrument of government revenue management. This paper examines the impact of capital account liberalization on government's tax revenue. I test the hypothesis empirically, using panel data on 149 countries over the period 1970-2017. Historically, I find that the positive impact of capital account liberalization on tax revenue is predominant in countries where the depth of the banking sector is greater.

One of today’s most important social and economic phenomena is the fourth industrial revolution, the effect of which is that digitalization can significantly transform business processes. The corporate controlling area cannot avoid transformation either, its methods and tools will change. Just as controlling itself, its changes can also differ between sectors, especially in the extremely diverse service sector. The aim of the research is to examine, on a domestic sample, whether there are differences in this respect between companies with a main commercial activity and the rest of the service sector. The data of the questionnaire research conducted with 46 controllers and managers were evaluated by means of cross-tabulations, averages and statistical tests. There are no differences in the digital development of the key performance indicators that form the basis of controller work, in the use of ERP systems, automation solutions and language algorithms. In the commercial group of the sample, the use of business intelligence tools providing advanced planning and analysis options is significantly more common. The two groups of the sample do not differ in terms of the factors encouraging the digitalization of the controlling area, but the companies with a commercial main activity differ in terms of the importance of the factors hindering the process: they are more averse to new technologies, more afraid of their usual positions, but perceive the financial aspects of the development to be less important.
Análise da assimilação de glicose e xilose em Papiliotrema laurentii UFV-1

A assimilação dos açúcares constituintes de biomassas lignocelulósicas é essencial para a produção de óleo por leveduras oleaginosas em biorrefinarias. Este óleo pode ser utilizado como matéria-prima para a produção de biocombustíveis derivados de ácidos graxos, contribuindo para atender à crescente demanda por biocombustíveis. P. laurentii UFV-1 é uma levedura oleaginosa capaz de converter glicose e xilose, os principais açúcares constituintes de biomassas lignocelulósicas, em óleo. O consumo simultâneo desses açúcares é primordial para se alcançar uma alta produtividade volumétrica de lipídios em biorrefinarias. Portanto, este estudo objetivou: i) analisar o perfil de consumo de glicose e xilose em P. laurentii UFV-1, e ii) selecionar linhagens mutantes capazes de assimilar glicose e xilose simultaneamente. O cultivo da levedura em meio mínimo Yeast Nitrogen Base (YNB) contendo diferentes concentrações de glicose e xilose permitiu estimar os parâmetros cinéticos do modelo de Monod. Os valores da constante de saturação (Ks) foram similares para as duas fontes de carbono e energia. Apesar de apresentar afinidades similares por glicose e xilose, P. laurentii UFV-1 consome glicose preferencialmente quando cultivada na presença dos dois açúcares. Esta linhagem foi submetida à mutagênese por irradiação ultravioleta, e linhagens mutantes foram selecionadas em meio de cultura contendo 2-deoxiglicose (2DG), análogo da glicose que induz a repressão catabólica, mas não é metabolizado. Dentre as vinte e quatro linhagens mutantes selecionadas, a linhagem M17 destacou-se por ter atingido uma maior densidade populacional no cultivo contendo 4 mM de 2DG. Surpreendentemente, as linhagens M17 e selvagem apresentaram o mesmo perfil de consumo de glicose e xilose. Isto indica a sua susceptibilidade à repressão por glicose. Todavia, o consumo simultâneo de xilose e 2DG mostra que a linhagem mutante é insensível à repressão catabólica induzida por 2DG. Este resultado sugere que as alterações genéticas que ocorreram na linhagem mutante foram específicas para aliviar a repressão catabólica causada somente por 2DG. O mutante M17 apresentou perfis de produção de lipídios e de crescimento nas temperaturas de 30 °C e 37 °C similares aos da linhagem selvagem de P. laurentii. Em relação à linhagem selvagem, observou- se que nas primeiras 24 horas de cultivo, o consumo de xilose foi reprimido na presença de 2DG. Após este período, ocorreu a secreção de 2DG, a qual foi acompanhada pelo consumo de xilose, indicando que a levedura apresenta um mecanismo tardio para contornar o efeito de repressão catabólica causado pelo análogo da glicose.

Introduction: The term sexually transmitted infections (STIs) refers to a variety of clinical syndromes caused by pathogens that can be acquired and transmitted through sexual activity. STIs are caused by more than 30 different pathogens including bacteria, viruses, protozoa, fungus, and ectoparasites. Sexual transmitted diseases can lead to serious health complications and affect individual’s future reproductive plans and responsible for 17% of the total burden of disease, There is limited study done about Sexual transmitted diseases on most of regions in Ethiopia specifically in Somali region and most studies that have been done in Ethiopia were community based studies. Therefore the aim of this study was to assess magnitude and associated factors of sexual transmitted diseases among adult clients attending at public health facilities in Jigjiga town eastern Ethiopia 2021. Methods and Materials: An institution based cross sectional study was conducted among adult clients attending Public health facilities in Jigjiga city Administrative from June 15 to july15, 2021. Data were collected from 398 respondents by using systematic sampling technique with proportional allocation of size employed to each health facilities. Structured interview questionnaires were used to collect the data. Data were entered into the computer using Epi-data 3.1 software and exported to Statistical package for social science version 20.0 for analysis. Binary logistic regression model was carried out for analysis to identify independent predictors at p-value 0.25. Results: The prevalence of reported ever had sexual transmitted diseases was found to be 34.5%(95%CI, 29.8-39.2) ,While assessing the independent predictors for acquiring STIs, clients who had sexual intercourse after having alcohol (AOR= 2.4; 95%CI: 1.0-6.0), clients who had multiple sexual partner in their life time (AOR=10.2; 95%CI: 3.6-28.3), as well as condom utilization was significantly associated with STD (AOR=0.064 95% CI; 0.023-0.17). Conclusion: This study shows high prevalence of STDs among respondents. Risky of sexual behaviors like having multiple sexual partners, sexual intercourse after having alcohol; multiple sexual partners and condom utilization during intercourse were significantly associated with STDs. As a result, every STDs consultation should include preventive education, such as reducing the number of sexual partners to reduce the risk of STD.

A vida exterior das fachadas: fotos e desenhos da rua Crémieux desde o Instagram
Authors: Fama Camila Montagner
Published: August 2023

O presente trabalho recupera referências da antropologia visual e do desenho no trabalho antropológico para pensar o que pode vir a ser a vida exterior das fachadas considerando imagens que apresentam as fachadas da rua Crémieux, localizada em Paris, França, publicadas no Instagram. O artigo compreende uma experimentação com desenhos que reapresentam as fachadas da rua Crémieux como uma composição na qual diferentes seres, organismos e coisas se encontram. Os desenhos buscam dar destaque às fendas pelas quais podem passar o pontual, o provisório e o performativo como componentes da vida exterior das fachadas. A feitura dos desenhos se guiou pelo intuito de seguir na contramão da tendência das mídias sociais de tratar a exterioridade máxima como destino final no qual as fachadas são relegadas a uma presença estanque, passiva e residual.

ABSTRACT: The proposal of this article is to recover references from visual anthropology and drawing in anthropological work to think about what the exterior life of facades can be, considering the images which present the facades of rue Crémieux, in Paris, published on Instagram. The article comprises an experimentation with drawings that re-present the facades of Rue Crémieux as a composition in which different beings, organisms and things meet. The drawings were made in order to highlight the cracks through which the timely, the performative and transitional can have its way as components from the exterior life of facades. The act of drawing was guided by the aim to go against the grain of the social media trend to take the maximal exteriority as a final destination on which the facades are demoted to a fixed, passive and residual presence.

Keywords: visual anthropology; images; Crémieux.

RESUMEN: La propuesta de este artículo es recuperar referencias desde la antropología visual y el dibujo en el trabajo antropológico para pensar lo que puede ser la vida exterior de las fachadas, considerando imágenes que presentan las fachadas de la rue Crémieux, en París, en Instagram. El artículo comprende una experimentación con dibujos que re-presentan las fachadas como una composición en la que se encuentran diferentes seres, organismos y cosas. Los dibujos se realizaron con el fin de resaltar las grietas a través de las cuales lo oportuno, lo performativo y lo transitorio pueden abrirse camino como componentes de la vida exterior de las fachadas. El dibujar se orientó a contrapelo de la tendencia de las redes sociales de tomar la máxima exterioridad como destino final en el que las fachadas se degradan a una presencia fija, pasiva y residual.
