Mathematics as structured knowledge, where properties and theories are made deductively based on defined or undefined elements and based on proven axioms, properties, or theories. Mathematics is also defined as a language of symbols about various ideas using defined terms. carefully, clearly and accurately. In the UPT Education Unit of SDN Bendogerit 2, Blitar City, there is a lack of cooperation with peers, this causes a lack of improvement in learning outcomes for students who are less intelligent. It can be seen in the initial learning that group and individual results are obtained, in group results from 5 groups only 1 group is complete or 20%, while in individual results from 20 students only 7 students or 35% have not achieved mastery of the material according to the KKM 75%. For this reason, classroom action research is needed using appropriate learning methods. The method used is the Peer Tutor Method which is a learning strategy that utilizes students who have privileges, intelligence and skills in the classroom to help provide explanations, guidance and direction to other students whose intelligence is somewhat lacking or slow in receiving lessons of almost the same age or classmate.

The Role of the Kresy Discourse in Constructing the Contemporary Identity of Poles in Lithuania
Authors: Pilarczyk-Palaitis Anna
Published: May 2023

The consequence of establishing new Polish state borders after the Second World War was the mass resettlement of citizens of the pre-war Second Polish Republic (II Rzeczpospolita) from the so-called Kresy – now newly established Lithuanian, Belarusian and Ukrainian republics of the Soviet Union – to the Polish People’s Republic (Polska Rzeczpospolita Ludowa). The 240,000 Poles, who left the Lithuanian Soviet Socialist Republic as part of the post-war resettlement, were only part of a group of over 1.4 million people resettled to ‘new Poland’. With extraordinary strength, they revived the 19th century myth of the Polish Kresy – one of the most important Polish national myths – which soon became an inseparable part of the Polish national discourse and the main element of Polish identity policy towards Poles who stayed in Kresy. This article is an attempt to answer the following question: What is the meaning of and role played by Kresy myth/discourse in constructing the identity of contemporary Poles living in South-eastern Lithuania – on the territory of these mythical Polish Kresy? The article is based on a series of interviews with Poles from Lithuania and representatives of governmental and non-governmental organisations operating for the Kresy, as well as an analysis of the content of these organisations websites with a project offer addressed to Poles in Lithuania.
The Influence of Orthodox Christianity on Economic Behaviour
Authors: Ćeranić Goran , Šarović Rade , Krivokapić Nataša
Published: May 2023

Weber’s very important theory on the influence of religion on economic behaviour was tested in the societies which belong to different cultural and religious circles. However, due to various socio-political circumstances, the testing of Weber’s theoretical-methodological framework has been largely neglected in the countries where Orthodox Christianity is dominant. However, the difficulties that arose in Orthodox societies during the post-socialist transformation, as well as the shift from the economic research paradigm to the cultural one on the global level, along with the revival of religion in Eastern Europe as one of the most important institutions of ideological and social life, contributed to the focus of our scientific interest be directed in this direction. The central questions that we tried to answer on this occasion were primarily related to the specifics of the concept of work in Orthodox Christianity and the relationship to the accumulation of capital.

Published: May 2023

The aim of this study was to investigate and compare the effect of Mulligan mobilization, lumbar traction and their combination on pain, functional disability and facet tropism in patients with facet joint syndrome. Sixty patients with facet joint syndrome from both sexes and aged 30 to 50 years participated in the randomized controlled trial design. They were referred from orthopedic and neurological clinics and divided into four groups as follows: group A received Mulligan mobilization and conventional treatment, group B received lumbar traction and conventional treatment, group C received Mulligan mobilization in combination with lumbar traction in addition to conventional treatment, while group D (control group) received the conventional treatment only. All participants received 3 treatment sessions per week for one month. The assessments were done before and after one month of treatment using Visual Analogue Scale (VAS) for pain, Oswestry Disability Index (ODI) for functional disability, and magnetic resonance image (MRI) for facet joint tropism. Statistically significant improvement was found in pain and functional disability in all four groups post-treatment (p<0.05), compared to pre-treatment, with the study groups (A, B and C) having a higher improvement than the control group (D). The improvement in group C was significantly higher than in groups A and B (p<0.05), and the improvement in group A was significantly higher than in group B (p<0.05). Regarding the facet joint tropism, there was a statistically significant improvement in the four groups post-treatment (p<0.05) compared with pre-treatment, with higher significant improvements in the study groups (A, B, C) in comparison with the control group (D). There was no statistically significant difference in tropism between groups A, B and C. The combination of Mulligan mobilization and lumbar traction (group C) was the most effective treatment for relieving pain and functional disability in patients with facet joint syndrome. Regarding facet tropism, there was a statistically significant improvement with all the treatments, but the conventional treatment produced the lowest improvement.

Published: May 2023

The aim of this study was to analyze the economic effects of elderly sports in Iran. The present study was qualitative. The research is based on grounded theory applying the emerging method attributed to Glaser (1992). Professors, of sports management, sociology, psychology, municipal managers and researchers (with at least two scientific research articles in the field of research) constituted the population of the current study. Since the purpose of qualitative sampling is information saturation, the combined theoretical sampling method of the improbably purposeful type was used until the theoretical saturation was achieved. A total of 15 participants were recruited as sample for the present study.  Acceptability, transferability and verifiability indices were used to determine validity. In order to evaluate the reliability of the interviews, the method of intra-subject agreement of two coders (evaluators) was used. Findings of the present study revealed that the mean age of the research participants was 48 years. Out of all, 75% participants were males. The average career background of the participants was 22.5 years and 80% of them held a Ph.D. degree. The results showed that the economic effects of elderly sports were divided into two categories: micro and macro. The macro level consisted of the two concepts of increasing GDP (5 signs) and private sector investment (3 signs). The micro level consisted of the two concepts of quantitative and qualitative improvement of production inputs (6 signs) and reduction of treatment costs (8 signs).

Published: May 2023

Individuals of the sports school can be children and young people who have no medical contraindications for sports. Once the athlete gets enrolled in a sports school after successfully completing the required documentation process, a written letter is provided by the director of the school. Followed by this, the child acquires the corresponding status and, from that moment, he or she has a number of rights and responsibilities. Most of the sports schools prohibit the substance abuse once youth or children become part of their organization. After getting enrolled in a sports school, a child has certain responsibilities, including the obligation not to use prohibited substances and methods. In this article, the authors examine the legality of imposing this obligation on a child. The authors concluded that the child is obliged to comply with the anti-doping rules of sports organizations, but at the same time he/she has no right to buy medicines and choose a doctor on his/her own, and these things must be done by parents according to the legislation of Ukraine.

Blind people need kinesthetic perception as feedback for providing information related to movement characteristics, such as position in space and direction. The research purpose was to determine the validity and test-retest reliability of of a kinesthetic perception test for blind people. The test consists of placing both the feet correctly on 4 square targets (5 cm thick) placed on the right, left, front, and back, at a distance of 100 cm from the initial position that is located in the middle, following the audio stimulus with a time limit of 10 seconds per repetition. The researchers used 3 experts to evaluate the validity of the test. The test-retest reliability was evaluated in a total of 50 people who were totally blind. Aiken V coefficient was used to test the validity and Cronbach’s alpha correlation test was used to test the test retest reliability. The research results showed a value of Aiken V of 0.86 > 0.77, and a reliability of 0.816 > 0.60. Therefore, it can be concluded that the kinesthetic perception test for blind people presented in this manuscript is valid and reliable.

À partir de l’étude de romans contemporains de science-fiction africaine (rédigés par Lauren Beukes, Nnedi Okorafor, Tade Thompson), ce texte vise à analyser ce que le lien animal nous dit des relations interespèces et des imaginaires politiques. Tour à tour utopies et dystopies, ces romans imaginent en effet des futurs africains qui formulent en réalité de féroces critiques à l’endroit du monde contemporain, en prenant l’animal comme personnage-clé, comme métaphore, ou encore comme perspective de symbioses inter-espèces.
Ordinary Language and Economic Language
Authors: Petrilli Susan , Ponzio Augusto
Published: May 2023

We explore the language of economics from the perspective of the relation between signs, language and ideology. The focus is on social reproduction in global communication. From the epistemological viewpoint linguistics and economics are interrelated, both are sign sciences and value sciences. Saussure’s general linguistics is modelled on economics, particularly marginalist “pure economics” from the Lausanne school. In the 1960s Rossi-Landi reconsiders the relationship between linguistics and economics, specifically political economy in the Smith-Ricardian and Marxian tradition. In this context linguistic value is not limited to the market, the synchronic axis, and confused with price. Critical of both Saussure’s Cours de linguistique générale and of Wittgenstein’s interpretation of “meaning” as “use”, Rossi-Landi (1966, 1968) – who can be reread today in light of globalized communication as proposed by A. Ponzio (2008) – investigates the production processes of linguistic value applying the theory of labour-value, thus speaker “linguistic work” accumulated in fixed capital (language) from one generation to the next. Thematization of the relationship between linguistics and economics contributes to understanding the concepts of “sign fetishism” and “sign materiality,” while the theory of “language as work and trade” and of “ideology as social planning” throw light on the question of “social alienation”, which in the language of the sign sciences is also “linguistic alienation” and more generally “sign alienation”.
Revealing Homo Donans: Liberating the Unilateral Gift from Commodity Exchange
Authors: Vaughan Genevieve
Published: May 2023

The nurturing of the infant from birth onwards provides an example of unilateral gift giving made necessary by the helplessness of the child who cannot exchange an equivalent for what she is given. This material transaction, the giving and receiving of goods and care, creates basic interpersonal schemas of material communication, which underlie verbal communication. They differ from the schemas created by quid pro quo exchange. The market economy is composed of both types of transactions, but unilateral gifts are given to and taken by the exchange transaction mechanism in order to create profit. Reinterpreting maternal care as a free communicative economy points towards a redefinition of the human as Homo Donans and provides a way out of the end of the world scenario to which capitalism has brought us. Using ideas of Marx, Vygotsky, Rossi-Landi, Sohn-Rethel, Lakoff, the findings of recent infancy research, interpersonal neurobiology and modern matriarchal (Goettner-Abendroth) and matricentric (O’Reilly) feminism, I propose a radical shift towards the gift paradigm.
Les « sorties sèches » à l’épreuve de la participation
Authors: Maameri Amira , Doris Julien
Published: May 2023

Cet article discute de certains enjeux liés à la modernisation des dispositifs de protection de l’enfance à la lumière de récents rapports publics diffusés en France et au Québec. Après avoir rappelé quelques-unes des grandes trajectoires et caractéristiques institutionnelles des deux systèmes, il propose d’interroger les conditions d’accès et de participation effective des enfants à la mesure de protection qui les concerne. Il propose ensuite de réfléchir à la systématisation de parcours d’accompagnement allant au-delà de la mesure de protection, dans le but d’enrayer le phénomène des « sorties sèches » des jeunes majeurs et des mineurs sortants. Enfin, il discute de la nécessité de repenser et d’adapter les conditions et les institutions de la protection de l’enfance, afin de mieux répondre aux besoins de certains groupes de mineurs et jeunes majeurs particulièrement vulnérables. Aussi, l’article met en exergue trois formes de convergences issues desdits rapports et dont les recommandations s’inscrivent, de manière globale, dans le virage participatif et le développement des capacités de résilience de l’enfance protégée.

Waste disposal is just one of the segments in solid municipal waste management system. During the entire life cycle of waste, starting from waste generation, through storage, collection, transport, recycling, treatment and disposal, several different pollutants are emitted. By disposing solid waste, non-road mobile machinery (NRMM) emits various pollutants into the air such as CO2, CO, NMVOC, PM, PAHs, heavy metals, etc. These substances can pose certain problems for human health and the environment. The subject of this study is the calculation of air emissions of CO2, CH4, N2O, NMVOC, PM10, CO, Cd, Cr and PAHs (chrysene and benz[a]anthracene) from NRMM which are included in the activities of receiving and disposing of waste at the Banja Luka landfill. The study evaluates the emission of pollutants using the EEA guidelines for the assessment of the emission of pollutants into the air, based on the consumption of diesel fuel during the year. This study, which is based on the calculation of NRMM emissions at the Banja Luka landfill, should serve as an example not only to other landfills but also to sectors that use NRMM on the importance of keeping track of pollutant emissions. The goal is to look at these emissions and introduce changes and improvements in this sector by replacing old NRMMs with new ones, optimizing operation, using diesel of satisfactory quality, etc.

Published: May 2023

Carpal tunnel syndrome (CTS) is the most common compressive neuropathy. The conservative treatment remains the first therapeutic choice in the treatment of mild and moderate CTS. The aim of this paper was to examine the average age of female patients with CTS diagnosed by EMNG, the frequency of bilateral CTS and its correlation with the age, and to determine the grade of electrophysiological damage of the nerve when the CTS diagnosis is confirmed for the first time. The retrospective examination included 187 female patients, aged from 27 to 79, with complains on unilateral CTS. All patients underwent EMNG for confirmation of CTS and the degree of damage to median nerve. Statistical analysis was performed by methods of descriptive statistics, Kruskal-Wallis test, and the Student t-test. The value of p 0.05 was considered statistically significant. The average age of the female examinees was 54.53 years. The bilateral CTS was confirmed in 67.9 %, most often of a moderate degree and more often on the right hand. No statistically significant difference was found in grades of CTS between the analysed age groups of patients that had the bilateral CTS (p = 0.206), nor there was a difference in years of life between the patients with unilateral and bilateral CTS (p = 0.638). Bilaterality of CTS, as well as the degree of the damage are not connected with age. The patients report timely for the first examination and diagnostics of CTS when there is still a possibility of the conservative treatment.

Published: May 2023

Extracurricular kinesiological activities, in addition to providing the opportunity for actively spend leisure time, significantly contribute to the improvement of children’s health and the development of their abilities, knowledge and achievements, so it is desirable to encourage and direct them. The aim of the study was to assess parents’ attitudes about physical activity and about encouraging children to extracurricular kinesiological activities in their leisure time. Also the aim was to determine the differences in parental attitudes about encouraging activities with respect to the child’s involvement in organized extracurricular kinesiological activities. The research was conducted on a sample of 191 parents of third and fourth grade primary school students. An anonymous questionnaire assessed parents’ attitudes about physical activity and about encouraging children to extracurricular kinesiological activities. Frequencies of answers were calculated, and the significance of the differences was determined by Man-Whitney U test. 79,58% of children were involved in organized extracurricular kinesiological activities, while 20,42% weren’t. Man-Whitney U test indicates the existence of statistically significant differences in parental attitudes related to activity encouragement. Parents whose children attend organized extracurricular kinesiology activities are more likely to encourage children to engage in physical activity.

One signature of the human brain is its ability to derive knowledge from language inputs, in addition to nonlinguistic sensory channels such as vision and touch. How does human language experience modulate the mechanism by which semantic knowledge is stored in the human brain? We investigated this question using a unique human model with varying amounts and qualities of early language exposure: early deaf adults who were born to hearing parents and had reduced early exposure and delayed acquisition of any natural human language (speech or sign), with early deaf adults who acquired sign language from birth as the control group that matches on nonlinguistic sensory experiences. Neural responses in a semantic judgment task with 90 written words that were familiar to both groups were measured using fMRI. The deaf group with reduced early language exposure, compared with the deaf control group, showed reduced semantic sensitivity, in both multivariate pattern (semantic structure encoding) and univariate (abstractness effect) analyses, in the left dorsal anterior temporal lobe (dATL). These results provide positive, causal evidence that language experience drives the neural semantic representation in the dATL, highlighting the roles of language in forming human neural semantic structures beyond nonverbal sensory experiences.
A ratchet-like apical constriction drives cell ingression during the mouse gastrulation EMT

Epithelial-to-mesenchymal transition (EMT) is a fundamental process whereby epithelial cells acquire mesenchymal phenotypes and the ability to migrate. EMT is the hallmark of gastrulation, an evolutionarily conserved developmental process. In mammals, epiblast cells ingress at the primitive streak to form mesoderm. Cells ingress and exit the epiblast epithelial layer and the associated EMT is dynamically regulated and involves a stereotypical sequence of cell behaviors. 3D time-lapse imaging of gastrulating mouse embryos combined with cell and tissue scale data analyses revealed the asynchronous ingression of epiblast cells at the primitive streak. Ingressing cells constrict their apical surfaces in a pulsed ratchet-like fashion through asynchronous shrinkage of apical junctions. A quantitative analysis of the distribution of apical proteins revealed the anisotropic and reciprocal enrichment of members of the actomyosin network and Crumbs2 complexes, potential regulators of asynchronous shrinkage of cell junctions. Loss of function analyses demonstrated a requirement for Crumbs2 in myosin II localization and activity at apical junctions, and as a candidate regulator of actomyosin anisotropy.

Natriuretic peptide signaling has been implicated in a broad range of physiological processes, regulating blood volume and pressure, ventricular hypertrophy, fat metabolism, and long bone growth. Here, we describe a completely novel role for natriuretic peptide signaling in the control of neural crest (NC) and cranial placode (CP) progenitors formation. Among the components of this signaling pathway, we show that natriuretic peptide receptor 3 (Npr3) plays a pivotal role by differentially regulating two developmental programs through its dual function as clearance and signaling receptor. Using a combination of MO-based knockdowns, pharmacological inhibitors and rescue assays we demonstrate that Npr3 cooperate with guanylate cyclase natriuretic peptide receptor 1 (Npr1) and natriuretic peptides (Nppa/Nppc) to regulate NC and CP formation, pointing at a broad requirement of this signaling pathway in early embryogenesis. We propose that Npr3 acts as a clearance receptor to regulate local concentrations of natriuretic peptides for optimal cGMP production through Npr1 activation, and as a signaling receptor to control cAMP levels through inhibition of adenylyl cyclase. The intracellular modulation of these second messengers therefore participates in the segregation of NC and CP cell populations.

The cell bodies of postganglionic sympathetic neurons innervating the heart primarily reside in the stellate ganglion (SG), alongside neurons innervating other organs and tissues. Whether cardiac-innervating stellate ganglionic neurons (SGNs) exhibit diversity and distinction from those innervating other tissues is not known. To identify and resolve the transcriptomic profiles of SGNs innervating the heart, we leveraged retrograde tracing techniques using adeno-associated virus (AAV) expressing fluorescent proteins (GFP or Td-tomato) with single cell RNA sequencing. We investigated electrophysiologic, morphologic, and physiologic roles for subsets of cardiac-specific neurons and found that three of five adrenergic SGN subtypes innervate the heart. These three subtypes stratify into two subpopulations; high (NA1a) and low (NA1b and NA1c) neuropeptide-Y (NPY) -expressing cells, exhibit distinct morphological, neurochemical, and electrophysiologic characteristics. In physiologic studies in transgenic mouse models modulating NPY signaling, we identified differential control of cardiac responses by these two subpopulations to high and low stress states. These findings provide novel insights into the unique properties of neurons responsible for cardiac sympathetic regulation, with implications for novel strategies to target specific neuronal subtypes for sympathetic blockade in cardiac disease.
Adaptive biasing of action-selective cortical build-up activity by stimulus history
Authors: Braun Anke , Donner Tobias H
Published: May 2023

Decisions under uncertainty are often biased by the history of preceding sensory input, behavioral choices, or received outcomes. Behavioral studies of perceptual decisions suggest that such history-dependent biases affect the accumulation of evidence and can be adapted to the correlation structure of the sensory environment. Here, we systematically varied this correlation structure while human participants performed a canonical perceptual choice task. We tracked the trial-by-trial variations of history biases via behavioral modeling and of a neural signature of decision formation via magnetoencephalography (MEG). The history bias was flexibly adapted to the environment and exerted a selective effect on the build-up (not baseline level) of action-selective motor cortical activity during decision formation. This effect added to the impact of the current stimulus. We conclude that the build-up of action plans in human motor cortical circuits is shaped by dynamic prior expectations that result from an adaptive interaction with the environment.

N6-methyladenosine (m6A) methylation of RNA by the methyltransferase complex (MTC), with core components including METTL3–METTL14 heterodimers and Wilms’ tumor 1-associated protein (WTAP), contributes to breast tumorigenesis, but the underlying regulatory mechanisms remain elusive. Here, we identify a novel cleaved form METTL3a (residues 239–580 of METTL3). We find that METTL3a is required for the METTL3–WTAP interaction, RNA m6A deposition, as well as cancer cell proliferation. Mechanistically, we find that METTL3a is essential for the METTL3–METTL3 interaction, which is a prerequisite step for recruitment of WTAP in MTC. Analysis of m6A sequencing data shows that depletion of METTL3a globally disrupts m6A deposition, and METTL3a mediates mammalian target of rapamycin (mTOR) activation via m6A-mediated suppression of TMEM127 expression. Moreover, we find that METTL3 cleavage is mediated by proteasome in an mTOR-dependent manner, revealing positive regulatory feedback between METTL3a and mTOR signaling. Our findings reveal METTL3a as an important component of MTC, and suggest the METTL3a–mTOR axis as a potential therapeutic target for breast cancer.
