Kemajuan teknologi informasi yang begitu cepat mendorong perilaku ekonomi yang berkembang pesat, diantaranya terciptanya uang digital atau uang elektronik. Uang Elektronik adalah alat pembayaran yang diterbitkan atas dasar nilai uang yang disetorkan telebih dahulu oleh pemegang kepada penerbit. Kemudian uang tersebut disimpan secara elektronik dalam suatu media uang elektronik yang dapat digunakan sebagai alat pembayaran kepada pedagang dan bukan penerbit. Lahirnya uang elektronik ini menimbulkan kontroversi di kalangan praktisi ekonomi syariah, diantaranya Dewan Pengawas Syariah Bank Muamalat Dr. Oni Sahroni, M.A yang mengatakan bahwa e-money yang digunakan saat ini adalah konvensional atau mengandung unsur ribawi karena beberapa hal: (1) Kontrak yang terjadi antara pihak e-money itu tidak jelas (gharar) dan tidak mengikuti skema transaksi syariah sehingga hak dan kewajiban para pihak tidak diketahui. (2) Bunga atas penempatan dana di Bank konvensional sebagai mitra penerbit e-money. (3) Hak pemegang kartu menjadi hilang pada saat kartu yang dimilikinya hilang. Untuk menjawab kegaduhan mengenai penggunaan uang elektronik ini, Dewan Syariah Nasional Majelis Ulama Indonesia (DSN-MUI) mengeluarkan fatwa tentang uang elektronik (e-money) syariah.

Data collection techniques used are: observation, and interviews. This research was conducted from August to October 2018. The results of this study showed that some Islamic Religious Education teachers in Asysyakirin Middle School had understood the meaning of the contextual learning model, the teacher just needed to deepen and gradually introduced the CTL (Contextual Teaching and Learning) learning model to student. The implementation of Islamic Religious Education learning more or less has reflected the application of the CTL (Contextual Teaching and Learning) learning model which includes 5 principles and 7 pillars of contextual learning, with the results of implementing the components of the CTL (Contextual Teaching and Learning) learning model as follows: interest (related), direct experience (esprecing), application (appliying), cooperation (cooperating), transfer of knowledge (transfering), constructivism (contruktivisem), finding (inquiry), asking (questioning), learning communities (learning comunity), modeling (modeling), reflection (reflection), true assessment (authentic assessment).

It is expected that all teachers can use active learning, to develop the learning process one of them by using the CTL learning model, because the implementation of CTL can activate students in the learning process and increase student motivation. Because there are still inhibiting factors in the implementation of CTL, it is expected to frequently attend seminars and workshops and frequently read books related to CTL learning to better master and deepen how the application of CTL is good and right. So that it can improve the quality of education on an ongoing basis and establish better interactions to be able to achieve the expected learning goals

Kecerdasan versi kajian barat tertumpu pada banyaknya penguasaan kosakata, mendengarkan dan memahami orang lain. Sedangkan kecerdasan menurut perspektif al-Qur’an lebih mengedepankan penguasaan terhadap siapa komunikan yang menjadi sasaran nilai-nilai Islam. Sehingga dengan penguasaan terhadap komunikan dapat menyusun strategi-strategi ungkapan kata yang paling tepat yang kiranya mampu menundukkan akal dan perasaannya di bawah tuntunan Islam. Pengetahuan terhadap kecerdasan verbal dapat menambah khazanah Islam dalam upaya untuk menerima Islam secara sukarela tanpa ada unsur paksaan sedikit pun, sebagaimana hal ini diterangkan melalui surat al-Baqarah/2:256

Kecerdasan berbicara bukanlah hanya kemampuan berbicara, namun lebih dari itu yakni kecerdasan memilih kata-kata yang tepat, adapun tujuan dari pemilihan kata yang tepat ini adalah pemahaman, kecerdasan tersebut dinamakan dengan kecerdasan verbal. Kecerdasan verbal dalam al-Qur’an dapat dilacak melalui sejarah para Rasul. Kecerdasan verbal yang dimiliki para Rasul memberikan dampak signifikan dalam dunia dakwah

Authors: G. Balasubramanian  , D. Salvia  , D. Bharathi
Published: August 2022

Due to rapid urbanization there is a great increase in building construction, so is the demoli-tion. There is no proper disposal of the demolition waste. About 530 million tons of C&D waste is generated annually. But only a few amounts of demolished concrete is recycled or reused. In this study, experimental investigations have been carried out to evaluate the effect of complete replacement of fine aggregate by dem-olition waste on compressive strength, which is compared with a conventional block. The concrete blocks were made in M20 mix. Further, the test was carried out in concrete paver block, in M40 mix design. The concrete paver blocks show 91% strength attainment at 28 days and it is only a marginal deterioration in the compressive strength. Therefore, the concrete blocks made with demolition waste can be used in low load bearing pavements.
Behaviour and Design of Steel I-Beam to Column End Plate Bolted Connections Based on Experimental and Numerical Investigations
Authors: A.H. Salem  , E.Y. Sayed-Ahmed  , A.A. Elserwi  , R.S. Aziz
Published: August 2022

Steel Beam to column rigid connections are required to transfer forces and moments. I-beam are commonly connected to columns using bolted end plates rigid connections, which are mainly subjected to bending moment and shear force. Behaviour of these connections have been extensively investigated. How-ever, besides being complicated, current methods of estimating bolt forces and plate thickness of the connec-tions do not consider the interaction between the bolt elongation and the plate deformation. An experimental investigation is performed on rigid beam to column bolted connections with flushed and extended end plates. Then, a numerical model accounting for geometric and material nonlinearities is built up. The model results are verified against the experimental investigation data. Using this model, a parametric study is performed on the connection. Interaction curves have been presented, which reveals the effects of the investigated parame-ters on the bolts’ forces, the prying action, the thickness of the end plate and the connection capacity. Modes of failure of these connections have been scrutinized showing two distinct modes: bolts failure or steel end plate yielding. The results of the investigation are used to perform a critical review of the procedures adopted by AISC for these rigid connections revealing the shortcomings of the AISC design procedures. Finally, de-sign charts and equations for the rigid end plate connections are introduced based on the results of the exper-imental and numerical investigation, which may significantly facilitate the selection of both the bolt’s diame-ters and the end plate thickness for the investigated connections.
Dynamic response of cracked concrete rehabilitated with composites
Authors: Shifana Fatima Kaafil
Published: August 2022

Disaster mitigation is one of the ongoing efforts in most of the countries to reduce the impact on people and property. The focus of the present study is to provide design inputs for rehabilitating beam structures using locally available composite materials based on linear and nonlinear dynamic analysis. This study models the tensile zone of a beam structure using finite elements with pre-assigned crack widths and crack depth. In linear modeling, the stiffness is assumed to vary linearly and in nonlinear modeling, bilinear variation of the stiffness is considered for analysis. The linear and non-linear response of cracked beam obtained from the finite element method is given as input for dynamic analysis. The frequency, time-period shift and amplitude are studied for uncracked beam, beams with damage for different types of cracks width and depth and design recommendation for rehabilitation of damaged beam with different types of composites are suggested.
Engineering Properties and Prediction of Strength of High Performance Fibre Reinforced Concrete using Artificial Neural Networks
Authors: P. Ramadoss  , NVN. Prabath
Published: August 2022

ABSTRACT: This paper presents the experimental and numerical studies on high performance fiber concrete (HPFRC) with water-cementitious materials (w/cm) ratios of 0.4- 0.3, steel fiber volume fraction (Vf) varying from 0- 1.5%, polypropylene fiber volume fraction varying from 0- 1% and silica fume replacement at 10% and 15%. Experimental results showed high improvements in 28 day cylinder compressive strength and flex-ural strength of steel fiber reinforced concrete at fiber volume fraction of 1.5%; for polypropylene (PP) FRC improvement in compressive and flexural strengths are marginal and moderate, respectively. Statistical models developed for compressive strength ratios and flexural strength ratios of HPSFRC indicate the prediction ca-pabilities of the models. Due to the complex mix proportions of HPSFRC and the non-linear relationship be-tween the concrete mix proportions and properties, research on HPSFRC has been empirical and no models with reliable predictive capabilities for its behavior have been developed. Based on the large data collected for HPSFRC mixes, a trained artificial neural network (ANN) model which adopts a back propagation algorithm to predict 28-day compressive strength of HPSFRC mixes was employed. This paper describes the comparison of the experimental results obtained for various mixes. Multiple linear regression (MLR) model with R2 = 0.78 was also developed for the prediction of compressive strength of HPSFRC mixes. On validation of the data sets by NNs, the error range is within 2% of the actual values. ANN models give the significant degree of ac-curacy compared to MLR model, and can be easily used to estimate the strength of concrete mixes.

Published: August 2022

The aim of present study is to determine the mechanical properties of hollow concrete block masonry externally bonded with coir and glass textile reinforced mortar composites. The properties of textile composites were determined by testing TRM Coupons. A total number of 39 prisms were cast. The block masonry prisms were externally bonded with coir and glass textile fibre mesh with mortar. The elastic properties of block masonry, shear and flexural strength were determined for both unreinforced and strengthened specimens. The results showed that increasing the number of layers of textile fibers, enhanced the flexural capacity of TRM coupons. The provision of connectors also enhanced flexural strength. The stiffness of unreinforced masonry prisms was found to increase by strengthening with textile reinforcements even though the increase in compressive strength is marginal. There is a significant enhancement in flexural strength and shear bond strength when compared to unreinforced masonry.

By obtained 3D simulation and contour pattern on PCC panel, it is found that the induced stress is bending pressure.
Study on the frost resistance durability of recycled aggregate concrete under an extreme cold environment
Authors: Su Qing
Published: August 2022

Recycled aggregate concrete (RAC), as a way to reuse waste concrete, is good for solving environmental and resource problems. In this paper, the frost resistance durability of RAC under an extreme cold environment was studied, RAC specimens with different replacement rates were designed, and then the indexes of the specimens, such as mass loss rate, were calculated and compared. It was found that with the progress of the freeze-thaw cycle, the higher the replacement rate of recycled concrete aggregate (RCA) was, the worse the frost resistance durability was. The mass loss rate of RAC-3 (100% RCA replacement rate) was 5.56%, the strength loss rate was 40.86%, and the relative dynamic elastic modulus was 61.89%, all of which were significantly lower than that of RAC-0. The experimental results verify that the excessively large replacement rate of RCA is not conducive to the frost resistance durability of concrete. The replacement rate of RCA needs to be paid attention to when used in an extremely cold environment.
Technical-economic studies about the effect of Nano-carbon black on asphalt mixtures

Published: August 2022

Nanomaterial have been considered as one of the new additives by researchers for use in asphalt pavement. In this study, economic analysis along with technical analysis of the effect of different percentages of Nano carbon black on a 1 km long road was evaluated. The results showed that the addition of Nano carbon black to the asphalt mixture in low percentages reduced the Marshall stability due to the lack of proper bonding between bitumen and Nano carbon black. By increasing the percentage of Nano carbon black in the asphalt mix, Marshall Stability increased. Also, Nano carbon black has clearly shown potential for improving the permanent deformation resistance of the modified asphalt mixture. During the Marshall Quotient test, more than two times increase in rutting resistance has been observed by adding more than 10% Nano carbon black to the asphalt mixture. On the other hand, the results of economic analysis showed that the project has become uneconomic in different percentages; however, due to the positive effect of adding Nano carbon black on the technical properties of asphalt mixtures, it is recommended that Nano carbon black be used sparingly in areas where the pavement suffers from a lack of load-bearing capacity.
Zwischen Fallibilismus und Hochmut
Authors: Lücke J. Winfried
Published: August 2022

In this paper I reconstruct Hegel’s famous critique of irony by drawing on present-day vice epistemology. I argue that the categories of contemporary theories of epistemic vices are sufficient to classify a type of irony as a vicious stance. Yet they fail to grasp the property in virtue of which irony deserves criticism. I show that, for Hegel, this feature is intellectual pride. In the remainder of the paper, I specify the axiological, metaphysical, and epistemological background assumptions which guide the self-assessment of proud persons according to Hegel. Finally, I throw some light on the theoretical presuppositions of Hegel’s account of irony and pride.

Published: August 2022

Objectives: We aimed to evaluate the impact of the tryptanthrin (TRP) compound, with antimicrobial and anti-inflammatory effects, on the excisional wound (EW) model. In an EW model in mice, we tried to explain the possible effect of TRP through vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) that contribute significantly to wound healing. Methods: A total of 90 BALB-C female mice aged 6 - 8 weeks were used in the present study. Animals were randomly divided into five groups. After creating the EW model, three different doses (1, 2.5, 5 mg/kg) of TRP compound were applied topically for 14 days, and wound closure rates were measured on days 0, 3, and 7. Vascular endothelial growth factor and MMP-9 were evaluated on days 3, 7, and 14 on wound explants and on day 14 on serum samples by enzyme-linked immunosorbent assay. Histopathological analysis was performed on wound explants. Results: After the EW model creation, significant healing of the wound areas was observed in the groups for which TRP was applied, especially on the third day. Moreover, in groups that received the third dose of TRP, the wound closure rate was 94%. It was found that the wound areas were closed due to the increase in TRP dose. In line with wound healing, VEGF and MMP-9 levels gradually rose on the third and seventh days and decreased on the 14th day. Conclusions: Tryptanthrin compound usage on the EW model increased wound healing and did not leave a scar after 14 days.

Background: Persian oak (Quercus castaneifolia C.A.Mey) belongs to the Fagaceae family. This plant is commonly used in Iranian traditional medicine to treat inflammatory and gastric ulcers. Objectives: This study aimed to assess the efficacy of Persian oak fruit aqueous hull extract on wound healing in rats. Methods: Thirty-five male Wistar rats were randomly divided into five groups, then two full-thickness wounds of 10 mm in diameter were created bilaterally on the back of the animals. The negative control group received saline, the positive control group was treated with phenytoin cream, and three treatment groups received 2%, 4%, and 8% Jaft aqueous extract. The animals received these medicines once daily for 15 days. The percentage of wound healing was evaluated using wound contraction ratio, re-epithelialization, tensile strength, vascular endothelial growth factor (VEGF), and platelet-derived growth factor (PDGF) content. Histopathological examination was performed on repaired tissues. Results: In the 2%, 4%, and 8% Jaft extract and the phenytoin groups, the wound closure rate was significantly higher than in the saline group. The treatment groups revealed significant healing improvement (P < 0.05) compared to the control group in wound contraction, tensile strength, epithelialization duration, VEGF, and PDGF plasma level. Histopathological investigations also exhibited development in wound healing with Jaft extract. Conclusions: This study shows that the Persian oak fruit hull aqueous extract was effective in wound healing in animal models. Clinical trials are required to prove the efficacy of Q. castaneifolia fruit hull spray in healing various wounds in humans.
The Primacy of Responsibility: Hannah Arendt and Emmanuel Levinas
Authors: Schües Christina ,   Philosophy Documentation Center
Published: August 2022

Responsibility is central to Emmanuel Levinas as well as Hannah Arendt. A reading of their understanding of the concept and role of responsibility for politics and ethics and in regard to its social-ontological status of primacy, its reference to historical, worldly, and human conditions, brings out the similarities and differences of their work. Regarding their historical context, they could have engaged in a dialogue; but they never did. Their personal temperament and thematic approach to key issues concerning the concept of responsibility—such as subjectivity, primordiality, or relationality—can be used to build pillars for a bridge between the two thinkers’ respective approaches. This essay tries to read each author in light of the other one.

Denne undersøgelses formål er at belyse de studerendes forskellige forståelser af, hvad teknologi er, samt at belyse forbindelsen mellem profession/erhverv, professionsidentitet og teknologiforståelse i forskellige bacheloruddannelser på Professionshøjskolen UCN. Derud- over undersøges, hvorledes de studerende vurderer teknologi i relation til deres egen professionsvdvikling. Det undersøges, hvilke forskellige teknologier de studerende anvender under uddannelsesforløbet, og hvilken betydning teknologi har for de studerendes professionsudvikling. De forskellige professionsstudieordninger og semesterbeskrivelser beskriver sparsomt, hvilke kompetencer de studerende skal have i relation til teknologi, ligesom der er meget forskelligrettede perspektiver på praksis og forståelser af teknologi. Formålet er således at få en større viden om, og indsigt i, hvilken betydning teknologi har for de studerendes forståelse af professionernes udvikling. Undersøgelsen peger i retningen af, at teknologiforståelsen i en speciﬁk praksis har betydning for teknologiers betingelsesskabende muligheder for de studerendes reﬂeksion i, over og med praksis.

Published: August 2022

Purpose: The main goal of this work is to present shadow banking in the financial sector. The specific aim is to present and classify non-banking financial intermediaries. For the purposes of the study, the following hypothesis was formulated: shadow banking poses a threat to the maintenance of the stability of the financial system in Poland. Design/methodology/approach: The research method used in the article is a critical analysis of the related literature on the basis of many studies and reports available on the market. Findings: The results of the literature review are the basis for statements about shadow banking in the financial sector. Other research should be devoted to the analysis of the stability of the financial system during the COVID-19 pandemic, because there will be many other factors that affect the functioning of banking or non-banking entities and also shape new directions of their development. Research limitations/implications: The review was limited to reports of the National Bank of Poland, the Polish Financial Supervision Authority and the Central Statistical Office (now Statistics Poland) only due to the necessity to standardize the sources of publication of research results. Originality/value: Conclusions from the review may inspire others to undertake research in previously unexplored areas. They may also be a guide to ensure its best possible quality.

Purpose: This paper attempts to answer the question to what extent the entrepreneurial ecosystems theory fits in with the social entrepreneurship phenomenon. The objective is to fill this gap by presenting findings from an integrative review of prior systematic reviews available in the entrepreneurial ecosystems literature. Design/methodology/approach: In the paper, we apply a scoping review and an umbrella review focused on an in-depth analysis of findings obtained in previous reviews, thus taking the form of a review aiming for theory development. Findings: Our paper contributes to addressing the gaps in the current literature on social entrepreneurship and ecosystems. First, it points to the different types of actors in social entrepreneurial ecosystems (SEE), whose existence may foster social entrepreneurship and facilitate creating social impact. Second, it brings into focus the potential of SEE by drawing attention to the fact that a productive entrepreneurial ecosystem (EE) results in job creation and reduction of unemployment, both of which are crucial for social entrepreneurship. Third, as a result of this scoping review, it proposes an extension of Isenberg’s model of EE which can be seen as a cumulative contribution to existing knowledge in the field. Research limitations/implications: This study has certain limitations typical for reviewing investigations. Originality/value: The special value of the paper can be seen in the scoping literature review itself. So far, there has been limited study on social entrepreneurial ecosystems, the role of entrepreneurial ecosystems in development of social enterprises, and conversely, the role of social “components” in entrepreneurial ecosystems.
Motivation to Work in the Context of COVID-19 Impact on Tourism Industry Enterprises
Authors:   Department of Management Theory, Faculty of Management, University of Economics in Katowice, Poland, Czernek-Marszałek Katarzyna
Published: August 2022

Purpose: To explore the work motivation of managers of tourism enterprises during the COVID-19 period. Design/methodology: Qualitative research conducted from April to May 2021 in a form of semi-structured interviews with twelve tourist entrepreneurs from the Silesian region. Findings: The COVID-19 caused changes in work performance, including a decrease of work motivation, in the tourism industry. However, at the same time, it stimulated the appearance of new sources of work motivation like, e.g., a desire to overcome the crisis, survival on the market, caring for the staff, a sense of professional passion or concern for the development of the branch or region. Several sources of work motivation were identified that were divided into intrinsic and extrinsic motivation of people managing tourism enterprises in the COVID-19 pandemic. Research limitations/implications: Research findings are not representative and cannot be generalized. It would be worthwhile to undertake future research on: how – over time – the pandemic and its course changed the attitudes of tourism entrepreneurs, including their motivation to work; whether this motivation differs when different: types of enterprises (e.g. catering and MICE), enterprise location (e.g. seaside/mountain), segment of tourists (e.g. holiday/business tourists) are considered; a larger sample of respondents with the use of a quantitative approach. Originality/value: COVID-19 caused not only a decrease in motivation to work, which is more often stressed in the literature, but also became an impulse to the emergence of new sources of managers’ work motivation that are completely different than before the pandemic. The identification and exploration of those sources, divided into intrinsic and extrinsic work motivation, create an added value of the paper.
Knowledge Transfer in Virtual Business Incubators
Authors:   University of Bremen, Germany, Reit Tatevik
Published: August 2022

Purpose: Virtual business incubators (VBIs) have become a rising phenomenon, as the role of digitalization in the entrepreneurial context has been gaining increasing relevance. The ongoing COVID-19 pandemic additionally underlines the importance of virtual solutions per se. To be effective, virtual business incubators must rely on effective knowledge transfer (KT). This paper aims to identify factors influencing knowledge transfer in virtual business incubators and to determine in which direction these factors influence KT. Methodology: For this purpose, a qualitative single case study is applied within an internationally acting virtual business incubator, using 12 semi-structured interviews with incubator management and staff, as well as incubatees. Findings: The findings suggest that precise communication, weak ties, heterogeneous contexts, and low engagement all influence knowledge transfer in virtual business incubators, each in a different way outlined in the paper. Research limitations/Implications: As a qualitative study, this research might be exposed to researcher bias and cultural bias. Originality/Value: This study extends the descriptive, conceptual VBI literature by adding the level of dynamic processes within the incubator. These new insights into the dynamic level enable precise intervention in the course of the KT, allowing challenges and strengths to be analyzed and understood theoretically and addressed and strengthened practically. This is indispensable to the successful operations of VBI processes.
Cosmología en la obra de Dante Alighieri. Génesis y fuentes
Authors: Salazar Muñoz Jorge Iván
Published: August 2022

Este texto explora algunas relaciones entre arte y ciencia; se concentra en un periodo especifico de la historia: la Baja Edad Media, y en un autor en particular: Dante Alighieri. La selección de la obra de Dante como objeto de estudio obedece a dos razones: en primer lugar, a su importancia histórica. Para muchos autores, La divina comedia es el texto central de la literatura medieval. Jorge Luis Borges llego a considerar el poema de Dante como un microcosmos del saber medieval. En segundo lugar, la obra de Dante, en especial La divina comedia, dado el objetivo general que desarrolla, permite una aproximación a diversas cuestiones de ciencia y de cosmología. Hay que recordar que el poema trata un amplio espectro de temas: filosofía, teología, moral y política. Las discusiones cosmológicas no constituyen el eje del texto, pero resultan inevitables, dado el plan general de la obra. Dante quería mostrar el recorrido simbólico y moral del alma a través de los reinos sobrenaturales: el infierno, el purgatorio y el paraíso. La geografía de estos reinos, en muchos casos, se acomodaba al saber de la ciencia medieval, especialmente en los versos del Paraíso. Otro tanto ocurre en el Convivio.
Value representations in the rodent orbitofrontal cortex drive learning, not choice
Authors: Miller Kevin J , Botvinick Matthew M , Brody Carlos D

Humans and animals make predictions about the rewards they expect to receive in different situations. In formal models of behavior, these predictions are known as value representations, and they play two very different roles. Firstly, they drive choice: the expected values of available options are compared to one another, and the best option is selected. Secondly, they support learning: expected values are compared to rewards actually received, and future expectations are updated accordingly. Whether these different functions are mediated by different neural representations remains an open question. Here, we employ a recently developed multi-step task for rats that computationally separates learning from choosing. We investigate the role of value representations in the rodent orbitofrontal cortex, a key structure for value-based cognition. Electrophysiological recordings and optogenetic perturbations indicate that these representations do not directly drive choice. Instead, they signal expected reward information to a learning process elsewhere in the brain that updates choice mechanisms.
An increase of inhibition drives the developmental decorrelation of neural activity
Authors: Chini Mattia , Pfeffer Thomas , Hanganu-Opatz Ileana

Throughout development, the brain transits from early highly synchronous activity patterns to a mature state with sparse and decorrelated neural activity, yet the mechanisms underlying this process are poorly understood. The developmental transition has important functional consequences, as the latter state is thought to allow for more efficient storage, retrieval, and processing of information. Here, we show that, in the mouse medial prefrontal cortex (mPFC), neural activity during the first two postnatal weeks decorrelates following specific spatial patterns. This process is accompanied by a concomitant tilting of excitation-inhibition (E-I) ratio toward inhibition. Using optogenetic manipulations and neural network modeling, we show that the two phenomena are mechanistically linked, and that a relative increase of inhibition drives the decorrelation of neural activity. Accordingly, in mice mimicking the etiology of neurodevelopmental disorders, subtle alterations in E-I ratio are associated with specific impairments in the correlational structure of spike trains. Finally, capitalizing on EEG data from newborn babies, we show that an analogous developmental transition takes place also in the human brain. Thus, changes in E-I ratio control the (de)correlation of neural activity and, by these means, its developmental imbalance might contribute to the pathogenesis of neurodevelopmental disorders.
