Authors:   Irkutsk State Transport University, FILIPPENKO NIKOLAY , LIVSHITS ALEKSANDR , CHUMBADZE TAMARA
Published: January 2023

The use of new modern structural materials that would improve the physical and mechanical properties of products, aggregates and components of agricultural machines will help to reduce the mass fraction of metals in their design. It was determined that the use of additive technologies in mechanical engineering is hindered by poor product quality due to the lack of automated control of the polymerization process in the production of 3D products. (Research purpose) The research purpose is developing an algorithm to the process of automated control of the technology of manufacturing products from photopolymers. (Materials and methods) A set of controlled parameters of the photopolymerization process was substantiated in the manufacture of parts using additive technologies, which were taken as polymerization time and the dynamics of temperature changes in the material. (Results and discussion) The results of the use of an automated photopolymerization process were given and its analysis was carried out on the example of a typical technological process for obtaining samples of polymer composites similar to natural organic materials. Thermal phenomena that occur when exposed to ultraviolet radiation during polymerization are described. We carried out experimental and industrial tests of the physical and mechanical properties of basic photopolymer resins, which in practice allowed us to investigate the operation of the algorithm of the process control system and conclude that all the indicators of the tested samples exceed in quality the values of samples from acrylic plastics made by the traditional method. (Conclusions) We have developed an algorithm for an automated system of extreme control of technological processes of manufacturing products using additive technologies using photopolymers and their composites. The beginning and end of the polymerization process were identified automatically, increasing the mechanical characteristics of the products. It has been shown that in the production of machine-building parts and, in particular, agricultural engineering, it is possible to use additive technologies.

Published: January 2023

Recently, due to the progress in the development of wind generators and solar panels, autonomous hybrid energy systems based on renewable energy sources, which include solar panels, wind generators and power units, have been used for reliable power supply to remote settlements. The vulnerability of a hybrid power plant is its dependence on external climatic conditions and power units require fuel. To solve this problem, it is proposed to supplement hybrid systems with the use of power systems based on the day-night temperature difference. Today, there are no developed circuit solutions for the structure of a hybrid electrical complex based on renewable energy sources with a system of daily temperature difference in its composition according to a scheme with a common AC bus. (Research purpose) The research purpose is developing electric circuits of an autonomous hybrid power plant based on renewable energy sources with a temperature change system taking into account the load and determining the turn-on time of the gasoline generator. (Materials and methods) Considered an electrical complex of hybrid type with four sources of electrical energy, which includes a system of daily temperature difference. (Results and discussion) We have developed schemes for an autonomous hybrid electrical complex based on renewable energy sources with a temperature change system and an alternating current bus for power supply to remote agricultural facilities. The problems of the complex when using several inverters operating on one AC bus in the circuit and ways to solve them were shown. We calculated the loads for each power system and deduced the condition for switching on the gasoline power unit in adverse weather conditions. (Conclusions) It was determined that the developed electrical circuits with a load control unit and a common master generator of a hybrid energy system based on renewable energy sources with a temperature difference power system allow creating an optimal mode of its operation and managing the entire hybrid system more efficiently.

The Covid-19 pandemic escalated demand for scientific explanations and guidance, creating opportunities for scientists to become publicly visible. In this study, we compared characteristics of visible scientists during the first year of the Covid-19 pandemic (January to December 2020) across 16 countries. We find that the scientists who became visible largely matched socio-cultural criteria that have characterised visible scientists in the past (e.g., age, gender, credibility, public image, involvement in controversies). However, there were limited tendencies that scientists commented outside their areas of expertise. We conclude that the unusual circumstances created by Covid-19 did not change the phenomenon of visible scientists in significant ways.
Linguistic Peculiarities of Bullying in Georgian and American School Discourse
Authors:   Batumi State University, Georgia, Shavadze Roin
Published: January 2023

Many scholars have investigated bullying as a social problem in educational institutions. However, just a few scientific works are available attempting to offer the analysis of the linguistic peculiarities related to bullying in school discourse. Since bullying is a violative act expressed verbally or physically to intimidate members of particular society, it is important to consider the linguistic features directly related to the language used by aggressors to harm victims. Consequently, in the present paper, we will explore certain verbal register (words, phrases, linguistic patterns, etc.) generally used by aggressors to insult, threaten or harm victims.
New Approach towards the EU Studies in Georgia
Authors:   Gori State University, Georgia, Kardava Ekaterine
Published: January 2023

The issue of the EU Studies development in Georgia is highly actual and important considering the fact that during the last 30 years’ path of European integration, the people of Georgia have not lost their faith and hope honorably to find a place in the EU family. The start of the association process in 2014 based on the AA/DCFTA (within the association trio) and the emergence of a European Perspective for Georgia in 2022, required a qualitatively new understanding of the content and methods of EU studies. The article presents one of the innovative attempts and approaches toward EU studies at the Gori State University, which was developed within the framework of the Jean Monnet Module "European Union Explored in Association Agreement". Sharing and disseminating the experience of a new style of EU studies could be useful for EaP countries and others oriented on European development.
Onomastic Material in the Proverbs of Kartvelian Languages: Marking and Generalization
Authors:   Ivane Javakhishvili Tbilisi State University, Georgia, Jgharkava Giorgi
Published: January 2023

Analysis of the vocabulary of proverbs and identification of the existing thematic fields is extremely important, because the lexical fund of paremic units is very close to everyday speech. Due to the social nature of proverbs, the form and content of a concrete word may point to the place of origin and/or spreading of the proverb. Analysis of the empirical material has proved that even within the related Kartvelian languages there may be thematically diverse paremic units, marked by the influence of local peculiarities. In this regard, special focus should be made on the onomastic material represented in proverbs. Since understanding locally marked proverbs is linked to additional problems for language learners, the issues raised in the article are equally relevant in the context of teaching a second language.
Political Engagement of the Russian Speakers in Finland
Authors:   University of Helsinki, Finland, Protassova Ekaterina
Published: January 2023

Russian-speaking immigrants in Finland, like many other immigrants in the world, are reluctant to express their opinions on politics. They do not consider themselves competent enough to have the right to make a judgment in a situation in which they have not taken part and which they cannot view completely on their own. Gradually, immigrants who were born in various countries are becoming increasingly aware of their place in their new society, but they still feel they cannot fully trust their leaders. This article examines the attitude of Russian speakers to the Finnish elections and the ongoing war in Ukraine as presented in media and social media, interviews, and essays. It is not easy to compare whether they are less involved than the young Finns, or it is a generational thing. The conclusion points out the difficulties in adapting to a different political system than in the country of origin and illustrates the spectrum of opinions among the immigrants of the first and second generation who live in Finland and use Russian among other languages in their everyday life. Russian-language media continue to have a significant influence on Russian speakers, even though secondgeneration representatives rely less on these sources of information.
Silence as Message (Gender-related aspects of communicative competence)
Authors:   Akaki Tsereteli State University, Georgia, Guchua Tamar
Published: January 2023

The 1920s saw the emergence of interest in gender-related issues of communication in the scholarly literature. Descriptive analyses of various cultural and linguistic patterns highlighted that there are speech communities within which women undergo linguistic discrimination in two ways: how they are taught to use language and how they actually use it. The present paper provides an analysis of the latter instance. Within the methodological framework of the Ethnography of Communication, and on the in/occurrence of components of the SPEAKING model, the paper aims at discussing speech events in which silence is a gender-specific fact. Illustrative data have been drawn from ethnographic records and travelogues. Such an analysis of the problem in point enables to discuss key issues of communicative competence and infer that, alongside acquiring vocabulary and grammar rules of a language, it is significant to be aware of who and when is expected to avoid verbal communication in a given speech community.
Māori and English in New Zealand toponyms
Authors: Matthews Philip W.
Published: January 2023

This paper takes up one of the conference themes, «Reflection of language contacts in proper names». It deals with the situation in New Zealand where there are some 12,000 gazetted (or official) and an estimated 35,000 nongazetted (or recorded) place names. These names are almost all in Māori and English. The country was settled by the Māori people in the fourteenth century and today about 650,000 people, out of a total population of about 4.3 million, claim Māori descent. Māori named almost all of the country, the names being closely linked to iwi (tribal) histories. Foreigners, almost all English speaking, started visiting the country and giving their names to various places, and from the early nineteenth century two place name systems – Māori and nonMāori – have existed. This paper details the contact between the Māori language, the English language and New Zealand’s place names. It deals with seven matters: (1) Māori settlement and naming; (2) Early nonMāori settlement and naming; (3) the Treaty of Waitangi; (4) post Treaty of Waitangi names; (5) spelling of Māori place names; (6) prounciation of Māori names; and (7) dual and alternative Māori-English place names. Reasons are advanced to explain matters associated with the interlingual problems in the spelling and pronunciation of the place names and the emergence of dual place names.
Stability-indicating RP-HPLC method applied to the quantification of anti-histaminic drug ebastine in its oral suspension dosage form
Authors: Koduru Swathi , Tatapudi Hemant Kumar , Kalepu Swathi , Mitta Chaitanya , Bairam Ravindar
Published: January 2023

For the quantification of ebastine in pharmaceutical suspension, a simple, quick, accurate, and exact stability-indicating HPLC approach was developed and validated. The drug was determined using a phase reverse system and the separation was performed in an analytical C18 column (250 mm x 4.6 mm, 5 μm). The mobile phase consists of 0.1% orthophosphoric acid and methanol in a 25:75, v/v ratio. Using a concentration range of 10–90 μg mL-1, the technique demonstrated a strong linear response (r=0.999). Effluents were measured at 262 nm while the flow rate was kept at 1.0 mL min-1. There was a retention time of 3.506 min. The method was statistically validated to determine its accuracy, precision, linearity, ruggedness, robustness, solution stability, selectivity, and forced degradation assessments. The stresses that were used were acid, alkali hydrolysis, water stress, oxidation, photolysis, and heat. Since the degradation products did not affect the capacity to identify ebastine, this technique may be taken as a stability indication. This methodology may be utilized for the analysis of Ebastine in pharmaceutical suspension, since the findings obtained were within the limits set by ICH standards.
A Chemical Framework for the Preservation of Fossil Vertebrate Cells and Soft Tissues
Authors: Anderson Landon A.
Published: January 2023

Reports of preserved cells and other soft tissues in pre-Pleistocene
vertebrates, including dinosaurs, have been met with controversy within
the field of vertebrate paleontology. To explain such reports,
Schweitzer et al. (2014) hypothesized that iron-mediated radical
crosslinking preserves ancient soft tissues in a manner somewhat
analogous to histological tissue fixation. In 2018, Wiemann et al.
proposed a second hypothesis that these soft tissues were preserved as
advanced glycation/lipoxidation end products (AGEs/ALEs). The
biogeochemistry underlying these hypotheses, however, remains poorly
described for fossil vertebrates. This review posits a novel chemical
framework describing the persistence of biological “soft” tissues into
deep time. The prior iron-mediated radical crosslinking and AGE/ALE
mechanisms are re-described in context of established chemistry from a
diversity of scientific fields. Significantly, this framework
demonstrates the hypotheses presented by Schweitzer et al. (2014) and
Wiemann et al. (2018) are, in many cases, subsequent steps of a single,
unified reaction mechanism, and not separate hypotheses. Knowledge of
the chemical mechanisms underlying vertebrate soft tissue preservation
has direct implications for molecular paleontology and archeology,
including efforts at molecular sequence recovery within the ancient DNA
and paleoproteomic communities. Such implications that are immediately
apparent from examining the chemical framework are discussed.
Population Genetics of Parasites and Their Arthropod Hosts
Authors: Bezányiová Kateřina , Straka Jakub
Published: January 2023

In comparison to organisms parasitising vertebrates, parasites of
arthropods are direly understudied despite their abundance, importance,
and potential usefulness. Due to their close relationship and
coevolution with the host, parasites can be used as tools allowing the
inference of information on host life history, ecology, and past events
the host species has experienced. Even though parasites comprise a
diverse assemblage of taxa, it is possible to identify convergent
patterns in their genetic population structure. Predictions of congruent
population genetic co-structuring between hosts and parasites can be
thus based on a few traits such as host specificity, life cycle
complexity or parasite and/or host dispersal. The parasite may even
provide better resolution of population structure than the host itself,
serving as a proxy that can be used to direct conservation projects of
both the host and parasite. Our review provides an overview of known
cases of host-parasite population co-structuring in arthropods,
identifies their common patterns, and discusses practical applications
of these findings.
A review of potential cardiac drug-drug interactions amongst patients presenting with cystic fibrosis exacerbation
Authors: Sooltan Ismail , Dzhakhangirli Firuza , Bulugahapitiya Sudantha
Published: January 2023

Drug-drug interactions inducing adverse drug reactions remain a
significant, avoidable health risk to cystic fibrosis (CF) patients.
With increasingly complex CF exacerbation treatment regimens being used,
the risk of clinically important drug-drug interactions has in turn
increased. Cardiovascular medications have reportedly been commonly
implicated in severe CF exacerbation drug-drug related reactions.
Therefore, knowledge of these potential drug-drug interactions is
essential for improvement of medication safety and preventing patient
harm. Drug-drug interactions can be classified into either
pharmacokinetic or pharmacodynamic. This article, using the British
National Formulary, details the drug-drug interactions between commonly
prescribed CF exacerbation medications and cardiac medications. For each
respective drug-drug interaction, the potential consequence, management
strategy and interaction severity have been described.
Decomposition of plate displacements via Kirchhoff-Love displacements
Authors: GRISO Georges
Published: January 2023

In this paper, we show that any displacement of a plate is the sum of a
Kirchhoff-Love displacement and two terms, one for shearing and one for
warping. Then, the plate is loaded in order to obtain that the bending
and shearing contribute the same order of magnitude to the fiber
rotations.
Explicit Face Memory Abilities are positively related to the non-intentional Encoding of Faces: Behavioral and ERP Evidence.
Authors: Sommer Werner , Kotowski Krzysztof , Shi Yang , Switonski Adam , Hildebrandt Andrea , Stąpor Katarzyna
Published: January 2023

Individual differences in face memory abilities have been shown to be
related to individual differences in brain activity. The present study
investigated brain-behavior relationships for the N250 component in
event-related brain potentials, which is taken as a neural sign of face
familiarity. We used a task in which a designated, typical target face
and several (high- and low-distinctive) nontarget faces had to be
distinguished during multiple presentations across a session.
Separately, face memory/recognition abilities were measured with easy
versus difficult tasks. We replicated an increase of the N250 amplitude
to the target face across the session and observed a similar increase
for the non-target faces, indicating the build-up of memory
representations also for these faces. On the interindividual level,
larger across-session N250 amplitude increases to low-distinctive
non-target faces were related to faster face recognition as measured in
an easy task. These findings extend the present knowledge about
brain-behavior relationships in face memory/recognition and indicate
that an advantage in non-intentional encoding of low-distinctive
non-target faces into memory goes along with the swift recognition of
explicitly learned faces.
Formation of pure anatase TiO 2 by reactive pulsed dc magnetron sputtering Method for controlling target poisoning state
Authors: Desch Nikolai , Lake Markus
Published: January 2023

The use of pulsed dc-sputtering sources for reactive magnetron
sputtering with oxygen offers a possibility to suppress negative effects
of target poisoning (such as arcing). This results in a wide process
range for the selection of a desired operating point. The control of
target poisoning plays a major role in maintaining constant coating
properties and affects the stoichiometry of the reactive coating, as
well as the coating rate and the economic impact of the coating process.
The target poisoning during the reactive sputtering of titanium under
oxygen addition proceeds nonlinear in a hysteresis. Without the use of a
suited target poisoning control technique the sputtering process can
abruptly change to an unstable state. As a result, variations of the
stoichiometry can occur during the deposition process. A proven method
for maintaining a stable reactive sputtering process is the control of
oxygen flow with the input variable target voltage. By determining the
typical oxygen hysteresis at constant target power and constant argon
flow, an operating point for the control loop is determined. The desired
target voltage then serves as the input variable for the control loop of
the target poisoning. The controlling technique for target poisoning is
a basic requirement for the production of the photolytic active anatase
phase of titanium dioxide by means of reactive magnetron sputtering. The
photocatalytic equipment of surfaces with a titanium dioxide coating in
the anatase phase can be realized with the reactive pulsed dc magnetron
sputter ion plating process (MSIP). The pulsed dc MSIP process provides
the ability to coat a variety of surfaces at temperatures below 200 °C
in an environmentally friendly manner.
Linking Soil Structure, Hydraulic Properties, and Organic Carbon Dynamics: A Holistic Framework to Study the Impact of Climate Change and Land Management
Authors: Jha Achla , Bonetti Sara , Smith A. Peyton , Souza Rodolfo , Calabrese Salvatore
Published: January 2023

Climate change and unsustainable land management practices have resulted
in extensive soil degradation, including alteration of soil structure
(i.e., aggregate and pore size distributions), loss of soil organic
carbon, and reduction of water and nutrient holding capacities. Although
soil structure, hydrologic processes, and biogeochemical fluxes are
tightly linked, their interaction is often unaccounted for in current
ecohydrological, hydrological and terrestrial biosphere models. For more
holistic predictions of soil hydrological and biogeochemical cycles,
models need to incorporate soil structure and macroporosity dynamics,
whether in a natural or agricultural ecosystem. Here, we present a
theoretical framework that couples soil hydrologic processes and soil
microbial activity to soil organic carbon dynamics through the dynamics
of soil structure. In particular, we link the Millennial model for soil
carbon dynamics, which explicitly models the formation and breakdown of
soil aggregates, to a recent parameterization of the soil water
retention and hydraulic conductivity curves and to soil carbon substrate
and O2 diffusivities to soil microsites based on soil macroporosity. To
illustrate the significance of incorporating the dynamics of soil
structure, we apply the framework to a case study in which soil and
vegetation recover over time from agricultural practices. The new
framework enables more holistic predictions of the effects of climate
change and land management practices on coupled soil hydrological and
biogeochemical cycles.
Spatio-temporal patterns of flooded areas in the lower part of the Sana river basin (Bosnia and Herzegovina)
Authors: Ivanisevic Marko , Savic Stevan , Pavic Dragoslav , Gnjato Slobodan , Popov Tatjana
Published: January 2023

Floods are the most frequent and devastating natural hazard event in Bosnia
and Herzegovina. The detected increase in extreme precipitation over the
study area in the last period has altered flood event patterns due to
climate changes. Higher frequency of flood events and lack of flood
protection infrastructure has a severe impact on socio-economic sectors and
natural ecosystems. This paper focuses on the identification of flooded
areas for each single flooding event in the lower part of the Sana river
basin during the period 2016-2020. For delineating flooded areas, both radar
and optical satellite imagery were used. Data obtained after processing
remote sensing images were overlaid with a detailed land cover map in order
to get insight into flooded land cover types. From temporal aspects, floods
are most common during the spring season. They are usually caused by rapid
snowmelt and prolonged excessive precipitation. Considering spatial aspects,
flooded areas vary from 110 to 522 hectares in the study area. Over 95% of
the flooded areas are arable land, meadows and pastures. Most affected
settlements by floods are urban and suburban area of Prijedor, Gomjenica,
Hambarine, Rakovcani, Rizvanovici, Brezicani, Donja Dragotinja, Vitasavci,
Svodna, Blagaj Rijeka and urban area of Novi Grad. The applied
methodological approach represents a starting point for further
investigation of flooded areas in the Sana basin and data obtained by this
analysis can be used in water management, spatial planning and emergency
planning.
Who cares? Neoliberalism, informal labour, and life-making
Authors: Cakardic Ankica
Published: January 2023

In this paper we develop a Marxist-feminist intervention into the phenomena
of informal labour and life-making through a social reproduction lens. In
order to approach these issues in a more consistent manner, we structure the
argumentation in two parts. After taking a few necessary theoretical and
methodological notes on neoliberal abolition of society and on Social
Reproduction Theory, in the second part of the paper we elaborate the
problem of informal labour and we link it to the recent crisis of care work.
We assert that this ?care crisis? arises from the neoliberal need for a
reconfiguration of reproduction, deepened by reassigning the responsibility
of care from welfare state to personal initiative and charity. Suggested
thematic inclination of the paper evokes the concept of ideological
formalization of family as a fundamentally ?anti-social unit? and critically
approaches the ideology of ?familialisation?. When it comes to the matter of
context and method, we depart from the premise that economic liberalism,
grounded in individualist premises, represents an ideological expression of
capitalism, and that family as a system for governing social reproduction
within households depends not only upon naturalisation, but also upon
individuation.
A Guide for Selection of Genetic Instruments in Mendelian randomisation (MR) studies of Type-2 diabetes and HbA1c: towards an integrated approach
Authors: Garfield Victoria , Salzmann Antoine , Burgess Stephen , Chaturvedi Nish
Published: January 2023

This study examines the instrument selection strategies currently employed throughout the type-2 diabetes and HbA1c MR literature. We then argue for a more integrated and thorough approach, providing a framework to do this in the context of HbA1c and diabetes. We conducted a literature search for Mendelian randomisation studies that have instrumented diabetes and/or HbA1c. We also used data from the UK Biobank (N=349,326) to calculate instrument strength metrics that are key in MR studies (the F-statistic for average strength and R2 for total strength) with two different methods (‘Individual-level data regression’ and Cragg-Donald formula). We used a 157-SNP instrument for diabetes and a 51-SNP instrument (as well as partitioned into glycaemic and erythrocytic) for HbA1c. Our literature search yielded 48 studies for diabetes and 22 for HbA1c. Our UKB empirical examples showed that irrespective of, the method used to calculate metrics of strength and whether the instrument was the main one or was partitioned by function, the HbA1c genetic instrument is strong in terms of both average and total strength. For diabetes, a 157-SNP instrument was shown to have good average and total strength, but these were both substantially smaller than those of the HbA1c instrument. We provide a careful set of five recommendations to researchers who wish to genetically instrument type-2 diabetes and/or HbA1c. MR studies of glycaemia should take a more integrated approach when selecting genetic instruments and we give specific guidance on how to do this.

Álgebra Linear nos cursos de Engenharia: entrevistas reflexivas com professores das disciplinas específicas
Authors: PHILOT JULIANA MARTINS , BIANCHINI BARBARA LUTAIF
Published: January 2023

O objetivo deste artigo é apresentar entrevistas reflexivas realizadas com professores que lecionam nas disciplinas específicas dos cursos de Engenharia, com o intuito de tentar compreender como e em quais disciplinas específicas a Álgebra Linear está inserida nos cursos de Engenharia. Essas entrevistas se enquadram na fase curricular e epistemológica, presentes na Teoria A Matemática no Contexto da Ciência, fundamentais para a construção de um evento contextualizado. A partir da análise das entrevistas, pudemos perceber que os professores compreendem os conceitos de Álgebra Linear, sabem em qual parte da disciplina é utilizada, porém não abordam problemas mais próximo da vida cotidiana do engenheiro, nem mesmo os professores que atuam na carreira de engenheiro e que muitas vezes esses conceitos são abordados em disciplinas do terceiro ano em diante, o que nos faz repensar se uma disciplina que dizem ser abstrata precisava mesmo ser lecionada nos anos iniciais dos cursos de Engenharia.

Multi-attribute group decision-making problem of medical consumption products based on extended TODIM-VIKOR approach with Fermatean fuzzy information measure
Authors:   Department of Mathematics and Humanities, MM Engineering College, Sethi T. , Kumar S. ,   Department of Mathematics and Humanities, MM Engineering College
Published: January 2023

The fundamental goal of this research is to develop a MAGDM (Multi-Attribute Group Decision Making) problem of Medical Consumption Products. We propose TODIM–VIKOR approach in this paper, which combines the TODIM (an acronym in Portuguese for Interactive and Multi-criteria Decision-Making) and VIKOR (Vlsekriterijumska Optimizacija I Kompromisno Resenje) procedures under Fermatean fuzzy information. A new Fermatean fuzzy scoring function is presented for dealing with comparison problems. In addition, we introduce a novel entropy measure for assessing the degree of fuzziness associated with an FFS. We also offer a Jensen–Shannon divergence measure for the Fermatean Fuzzy set that can be used to compare the discrimination information of two FFSs. This suggested measure meets all mathematical standards for being considered a measure. We introduced entropy and divergence measures to determine the objective weight in the TODIM–VIKOR approach. Meanwhile, to deal with multiple attribute group decision-making, a new decision procedure based on the suggested Entropy and Jensen–Shannon divergence measure was proposed in a Fermatean Fuzzy environment. In this article, TODIM has in view to find out the overall dominance degree, and VIKOR is to determine the compromise solution. Finally, we manage a supplier selection problem to verify the performance of the suggested Fermatean fuzzy TODIM–VIKOR method by comparing the ranking solution to the rankings of existing methodologies. We investigate the reliability and effectiveness of our proposed methodology.

Towards the Operationalization of the AfCFTA Trade in Services Protocol: Do FDI and ICT Enable Trade in Services for ECOWAS Countries?
Authors: Wonyra Kwami Ossadzifo , Cassama Braima Luís Soares , Gnedeka Kodjo Théodore
Published: January 2023

In January 2021, the AfCFTA entered its operational phase. This AfCFTA covers the liberalization of trade in services with a Protocol on Trade in Services. In this context, this paper examines the effects of FDI flows and ICT infrastructure on services exports, both globally and by sector in ECOWAS countries. We use panel data on the 15 countries for the period 1998 to 2020 and perform dynamic modeling using the LSDVC technique. The results reveal that the infrastructure ICT (internet and mobile telephony) does not directly affect services exports. However, overall, the interaction between ICT infrastructure and FDI positively and significantly influences services exports. The effects of the interaction between ICT and FDI have varying impacts on services exports across different sectors.
Digitalization of Zakat in Stimulating Community Socio-Economic Development in the Middle of the Covid-19 Pandemic (Maqashid Syariah Perspective)
Authors: Rizal Syamsu , Pakkanna Mukhaer
Published: January 2023

The Covid-19 pandemic seems to have harmed people's lives, especially in social and economic aspects. The Islamic finance sector can solve these problems because, in principle, Islamic economics aims to achieve public welfare. Zakat, infaq, alms and waqf is one form of activity in Islamic economics, which is part of the form of compulsory worship and advice from Allah SWT. Previous studies have stated that the management and distribution of zakat, from direct assistance to community empowerment assistance, is effective in helping improve the community's social and economic welfare. Applying zakat with the community's principles and returning to the community can encourage economic equity, especially during the Covid-19 pandemic, like today, where many people's economic activities are hampered. The digital zakat system is a breakthrough to increase the effectiveness of the management and distribution of zakat to the community. The digitization of zakat also makes it easier for the community to distribute zakat obligations. Coordination from various parties, such as the government, zakat institutions and academics, is needed in developing the zakat digitization system to achieve maximum results. With the application of Maqashid Syariah in managing digital zakat, it is hoped that zakat can be right on target in meeting human needs.

Online product reviews have grown into a valuable source of information influencing purchases with the rise of digital and social media. Customer reviews are a type of feedback for online stores and electronic commerce. Nowadays, consumers have constant access to online product reviews because to resources like smart phones, 24x7 internet access, and other resources to access websites. This product review has developed into a well-liked and successful marketing and sales tool that influences consumer product purchase behaviour. There are many platforms, such as online retailer websites, E-Commerce websites, brand websites, brand community blogs, and third-party reviews, where consumers can participate and engage in discussions about their purchase and consumption experience. Consumer opinions may influence the overall product sales and assist a customer in making a purchase. The goal of this study was to determine whether there is a link between consumer reviews and consumer buying habits. The purpose of this study is to clarify how various internet reviews affect consumers' purchasing decisions and intents. Online customer reviews (OCRs) are now a key resource for product details and have a significant impact on consumers' purchasing decisions. The decision-making process for consumer purchases has been significantly impacted as a result. OCRs' implications on customer behaviour have recently drawn a lot of scholarly interest. Therefore, it is necessary to review these impacts. The most recent research on the connections and linkages between OCRs and client buying is thus examined in this study.

Published: January 2023

Despite making up over 50% of the nation's total population (48%) and contributing only 34% to economic growth, women's participation in that process is limited. To develop a meaningful career for themselves, women are now taking on entrepreneurial roles. Although small in size, the small enterprises have had a significant impact on the Indian economy by helping to decentralise resources from the male to the female side, making them better suited to employing women. The present study aims “to identify the socio-economic factors that limit women's entry into entrepreneurship and those that adversely affect their performance”. Additionally, it highlights the fact that institutions have created specialised programmes for women entrepreneurs and how, particularly in recent years, these programmes have improved the socioeconomic circumstances of women entrepreneurs.

"This study examined science teachers’ attitude towards the use of mother tongue for instruction in Basic Schools, employing a descriptive survey design. The respondents were selected through purposive and convenience sampling techniques and data were collected from a sample of 162 Basic School Science. The questionnaire used for data collection was titled “Science Teachers’ Attitude towards the Use of Mother Tongue in Instruction Questionnaire (STAUMTIQ)”, which yielded a reliability coefficient of 0.83 using the test-retest method. Descriptive and inferential statistical tools were used to analyse the data. The findings showed that science teachers’ attitude towards the use of mother tongue for instruction in Basic schools was negative. Teachers’ gender, school type and teaching experience did not influence their attitude, while educational qualification influence their attitude towards the use of mother tongue for instruction in Basic Schools. It was recommended that teachers should be encouraged to implement the language policy provision on the use of mother tongue for instruction, especially in Basic Schools in Bayelsa State, Nigeria. "

OBJECTIVES

To evaluate the effects of the chondrodystrophy-associated FGF4L2 retrogene on intervertebral disc (IVD) calcification and vertebral geometry.

ANIMALS

22 Nova Scotia Duck Tolling Retrievers (NSDTR) with no FGF4L2 retrogene (n = 7, wild-type dogs), 1 retrogene copy (8, heterozygous dogs), or 2 retrogene copies (7, homozygous dogs).

PROCEDURES

Computed tomography (CT) scans of the vertebral column were analyzed using computer-aided design (CAD) software. IVD calcification, vertebral column length, and vertebral geometry of the third cervical (C3), 13th thoracic (T13), and first lumbar (L1) vertebrae were compared.

RESULTS

IVD calcification was not found in wild-type dogs. IVD calcification was more frequent in homozygous dogs than heterozygous (P = .008) or wild-type dogs (P < .001) and in heterozygous dogs compared to wild-type dogs (P < .001). Four IVDs were subclinically herniated in 3 dogs (2 homozygous, 1 heterozygous). Calcified IVD had a greater volume and surface area in heterozygous dogs than homozygous dogs. C3 vertebral canal height-to-width ratio was greater in homozygous dogs than heterozygous dogs (P = .044) and wild-type dogs (P = .010).

CLINICAL RELEVANCE

IVD calcification and vertebral geometry can be analyzed using CAD software. The presence of 1 or 2 FGF4L2 copies in the absence of the FGF4L1 retrogene has an additive effect on the number of calcified IVD and a minor effect on vertebral geometry in NSDTR dogs. Data support the use of FGF4L2 phenotyping to reduce clinical disease in segregating breeds and to monitor the introduction of wild-type alleles into fixed breed populations.
