A Model for Describing the Management Processes in the Scientific Sector. Fundamental Principles
Authors: Shepelev Gennady
Published: December 2023

A model has been developed to describe the management processes in the scientific sector. The model is based on the analysis of various types of work with knowledge (generation, storage, transfer, systematization and use). The scientific sector is considered as a sector of the economy specializing in the systematization of knowledge, in particular the development of scientific models of various phenomena. Because of their nature, scientific models are abstractions and can be an independent subject for research that is only indirectly based on the demands of the real economy. Scientific models also have predictive capabilities. This is the basis for their use in applied research. Thereby, using the developed management model, we show that the scale and specialization profiles of the scientific sector depend on the needed volume of work with knowledge. Specialization in working with knowledge is not absolute, because in addition to specialized institutions, organizations that are not scientific in the legal sense and individual specialists who work beyond the scientific sector can also do such work. Alternative models implicitly used in the management of the scientific sector are considered.
Expert Knowledge for Economic Policy: Is It Time for the “One-armed Economist” to Retire?
Authors: Shastitko Andrey , Zyubina Anastasia
Published: December 2023

The authors evaluate prospects of a new quality of relations between the holders of economic expertise based on scientific research, attention to essential (including interdisciplinary) details and its beneficiaries in the field of political decision-making. We substantiate the necessity of finding a compromise between what is interesting to a researcher and what is relevant for the development and application of economic policy measures in the light of the opposition of functionalist and fundamentalist approaches to the formation of interdisciplinary and sociopolitical discourses.
Attitude of Russian Youth to the Idea of Unconditional Basic Income – Understanding, Motives, Misconceptions
Authors: Andreenkova Anna
Published: December 2023

In recent years, the idea of a universal basic income (UBI) has begun to be widely discussed as a way to reform the social security system. For the effective implementation of this system, a high level of public consent is required, since it will affect all social groups. According to the Russian Social Survey (RSI) under the ESS programme, support for UBI among the Russian population is one of the highest in Europe. Most of all, UBI is supported by young people. Based on the tenth wave of RSI, hypotheses about the grounds for the formation of attitudes towards UBI among Russian youth were tested - the utilitarian-pragmatic theory of interests, the value theory and the “level of opinion formation” hypothesis. Significant differences were found in attitudes towards UBI between gender groups, people with different levels of education, economic status, different family structure, experience of unemployment and work-life balance. Among the value factors, support for measures to reduce economic inequality and the value of independence showed the strongest relationship with a UBI. However, in general, the first two hypotheses cannot convincingly explain the phenomenon of support for UBI among young people. The results of cognitive interviews conducted as part of the CESSI-Monitor national survey showed that the opinion about UBI among young people in Russia is still poorly formed. The majority of respondents gleaned basic information about UBI from the very name of the concept during the interview. Positive opinion about UBI arose due to the idea of ​​guaranteed additional income mentioned in the name. Such aspects as unconditionality and universality either have not yet found understanding or are perceived contradictory. Those who view a UBI as a system of equitable distribution of natural resource rents and national wealth have a positive attitude towards the idea of universality and equality in the distribution of such income. Those who emphasise the fact that UBI is funded by taxpayers perceive the idea of inclusiveness and equality without regard to merit and need negatively. In general, low awareness of UBI and poorly formed opinions lead to its instability. New arguments and clarifications can significantly change the picture. Therefore, it is still premature to talk about deep support for the UBI idea among Russian youth.

The article presents the study results of carbonaceous rocks and taxonomic diversity of the Upper Ordovician calcareous algae of the Tachalov section left half, located on the left side of the same-name creek in the central district of the Charysh-Inya structure-facies zone of Gorny Altai. Six microfacies are distinguished in rocks: algal-bacterial boundstones, crinoid mudstones, crinoid-algal wackestones, polybioclastic wackestones, crinoid-algal packstone-wackestones and crinoid-algal packstones. Calcareous algae of the following genera were recorded in limestones: Proaulopora Volgdin, 1934 (Ms), Girvanella Nicholson et Etheridge, 1878, Vermiporella Stolley, 1893, Apidium Stolley, 1896, Ortonella Garwood, 1914, Contexta Gnilovskaja, 1972, Halysis Høeg, 1932, Rothpletzella Wood, 1948. It is found, that during the formation of biohermal buildups in more active hydrodynamics, different groups of calcareous algae react either by increasing species diversity (like green algae) or by increasing the number of organisms of the same species (like red algae).

The present paper gives the structure analysis of the lower section part of Riphean-Vendian sediments of the Nyuya zone in the south-east of the Siberian Platform. The study results showed a complex heterochronous structure of the Talakan Formation section. The sharp difference in lithological rock composition, presence of depositional breaks of the Lower Talakan Subformation does not allow leaving this part of the section as a part of the Talakan Formation. It is proposed to refer the deposits of the lower part of the Talakan Formation to the older ones. The article is a continuation of series of works devoted to the improvement of stratigraphic schemes for the Vendian-Riphean of the Siberian Platform.

The paper is aimed at the research practice on identifying the features of interaction in the water-rockcarbon dioxide system in relation to terrigenous reservoirs, widely occurring in hydrogeological basins in the territory of the Russian Federation and potentially suitable for the placement of carbon dioxide. As the CO2 solution is saturated, along with an increase in total dissolved solids there is a naturally-determined increment in the volume of transition of ions into their complex forms. The main macro components (Ca2+, Mg2+, Na+, K+, (SO4)2–, Cl– ) migrate mainly in the form of their own ions, with a decrease in their fraction by an order of 1–3 % with an increase in mineralization. Ions such as Fe, Al3+, Mn3+, (NO3)–, (HCO3)–, SiO2, (NH4)+, (NO2)– are prone to transition into the form of complex compounds, the fraction of which in the total volume increases with the amount of saturation of solution with carbon dioxide. When CO2 is injected into the terrigenous reservoir, there is a natural decrease in the solution pH, absence of precipitation of carbonates and minimal changes in the rock porosity. The observed process of dissolution of primary aluminosilicate minerals (albite, anorthite, potassium feldspar) is characteristic of most of the considered mineralogical varieties of reservoirs, when they are saturated with CO2. This process is accompanied by deposition of secondary mineral phases in the form of montmorillonites, illites, chlorites, etc. Taking into account the low rates of these reactions, no significant changes in reservoir properties are noticed.

The paper deals with a detailed study of the Holocene core of drilling peat deposits of the upland (oligotrophic) Dulikha bog. Based on the results of non-destructive X-ray fluorescence analysis, SiO2, Al2O3 and Fe2O3 oxides predominate in the peat deposit chemical composition along the section depth. The main minerals of the peat ash part are mica, quartz, plagioclase, bassanite, potassium feldspar; secondary one is chlorite, accessory ones are amphibole, illite. The study results of peat substance by energy-dispersive X-ray microanalysis showed that peat deposits are represented by a mixture of particles and conglomerates of various shapes and sizes. The elemental composition of the main matrix of samples is presented by an organic component with a high content of C and O and silicate mineral component with a content of Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe. Single small bright particles of facetted and semi-facetted shape with a high content of Fe, Ti, Ca, Ba and W occur in almost all studied peat samples. The mineral component of these particles may be represented by magnetites, titanites, single metal granules. The upper interval of the peat bog section (0-20 cm) is characterized by increased concentrations of Cu and Zn, that may be due to both anthropogenic stress on swamp ecosystems and high biophillyng, i.e. the ability to accumulate living matter.

In this study, eco-friendly microwave-assisted esterification reactions of chenodeoxycholic acid with medium-chain diols (1,2-ethanediol, 1,4-butanediol, 1,6-hexanediol, 1,8-octanediol, and 1,10-decanediol) or tetraethylene glycol were accomplished. The synthesized bile acid esters were obtained with high yields (up to 81 %) and purity in a short reaction time (15 min). It is shown that the microwave technique is a suitable method for the preparation of chenodeoxycholic acid esters. In order to obtain detailed insight into the lipophilic behavior of the studied chenodeoxycholic acid esters, a comparative study of chromatographic behavior and lipophilicity was performed. Also, the present study deals with the estimation of pH – logD profiles in order to get an overview of the changes in lipophilicity related to the pH value changes. The obtained results indicate that studied compounds have logD values in the range acceptable for potential drug candidates. Chromatographic lipophilicity of synthesized chenodeoxycholic acid esters successfully correlate with in silico lipophilicity descriptors.

Published: December 2023

In this work, we developed an UV-visible (UV-VIS) absorption spectrometric method for the quantification of sodium diclofenac in natural waters. Several UV-VIS absorption method parameters were optimized. The maximum absorption wavelength was comprised between 276 and 292 nm, depending on the solvent, with molar absorption coefficients greater than 104 L mol-1 cm-1. The linearity of the UV-VIS calibration curves extended over one to three orders of magnitude, with correlation coefficients (R2) very close to unity. The low relative standard deviation (RSD)  values indicated a good reproducibility of the measurements. Analytical applications to natural waters yielded satisfactory results with average recovery rates between 94.7 and 99.1%.
The net peak splitting phenomenon in square-wave voltammetry – A simple diagnostic tool to distinguish between surface electrode mechanisms associated with different chemical reactions
Authors: Gulaboski Rubin
Published: December 2023

Utilizing pulse voltammetric techniques for the electrochemical analysis of lipophilic redox systems has proven to be an effective method for studying a diverse range of redox compounds, from simple molecules to intricate proteins. To extract relevant thermodynamic and kinetic data from electrochemical analysis of redox systems exhibiting strong surface activity, there's a crucial need to decipher the underlying electrochemical mechanism in the system being examined. The "split net peak" phenomenon, a defining characteristic observed in all surface-active redox systems featuring fast electron transfer under square-wave voltammetry conditions, has been investigated in this study to establish diagnostic criteria for identifying surface electrochemical mechanisms associated with preceding, subsequent, regenerative, and reactant-inactivating chemical reactions. This understanding can be achieved by tracking the influence of the chemical reaction rate on the split square-wave voltammetric peaks in a particular electrochemical mechanism. The approach reported in the current work enables a very simple and precise differentiation between the elaborated mechanisms frequently encountered in protein-film voltammetry methodologies.
Deneyim-Sünnet İlişkisi

Deneyim, özellikle modernitenin yeni olan üzerindeki ısrarı nedeniyle modern sonrası dönemle birlikte yoksullaşmaya başlamıştır. Modern olanın kendinden önceki ile arasına koyduğu mesafe, deneyimi aktarılan haliyle sorunlu hale getirmiştir. Artık modern dönemde anlık üretilip, anlık tüketilen deneyim türü tercih edilir olmuştur. Yaşanılan deneyimden yana yapılan bu tercih, deneyimin tekrar ve fark üzerine kurulu çift değerliliğini ortadan kaldıran, iç içe olmaktan çıkartan bir netice vermiştir. En kozmik olandan en antropik olana dek hayatın her alanının müphem olduğunu varsayan makalenin yazarı, bu çalışmayla sözlü, yazılı, ameli her türden gerçekleşen Sünnet uygulamasını deneyim üzerinden ele almayı amaç edinmiştir. Öncelikle belirtilmesi gerekir ki, Peygamberler de dâhil olmak üzere her kişinin gerek tekil bir deneyimi (örnek) gerekse de yaşantısı boyunca ortaya koyduğu bütüncül deneyimi (örüntü) olmaktadır. İddiamız odur ki bu iki tür deneyim de bir başkasına ancak örnek olabilir. Herhangi biri bir başkasının deneyimini kendisine örnek olarak alabilir, ancak örüntüsünü olduğu gibi alması imkân dâhilinde görünmemektedir. Ayrıca üzerinde durulması gereken bir başka önemli husus da Hz. Peygamber’in mezhepler arasında ihtilafı doğuran farklı deneyimleridir. Hz. Peygamber benzer deneyimlerde farklı uygulamalara gitmiştir. Bu tarz bir örüntü bize göre hayatın müphemlik dokusu ile örülü olmasıyla alakalı bir husustur. Yani Hz. Peygamber’in Sünneti/örüntüsü müphem bir karakter arz etmektedir. Dolayısıyla Peygamber Sünnetinin kendisinden sonraki kuşaklara aktarımında yaşanan sorunlarda, deneyimin kendine özgü ve tekrarlanamazlığı vasfı belirleyici olmaktadır. Konunun doğasına uygun olarak yapısöküm yönteminin tercih edildiği bu çalışma ile deneyimin bitimsiz keşif yolculuğu deneyimlenmek istenmiştir. Sünneti de takip edilen yol olarak düşünürsek, her yolcu, başkasının yerine yürüyemeyeceğinin bilinciyle kendi metnini yazmak durumundadır.
Supporting decarbonization through vehicle rightsizing, automation, and ride-splitting
Authors: Hawkins Jason , Kockelman Kara
Published: December 2023

Vehicle automation and smartphone app-based ride-splitting are commonly discussed topics in the transportation literature. While these technologies have been examined for their role in transportation decarbonization through simulation study, the motivation for such work is rarely made explicit. In this commentary, we provide a motivation for research in this area based on our own simulation research, as well as land use and vehicle operational factors. Specifically, land use factors such as density and the speed of its adjustment make traditional transit operations using large vehicles cost-prohibitive in most U.S. communities (and many other communities around the world). Automation and ride-splitting technologies may offer digitized transportation solutions that can match vehicle size to local land development density and passenger demand. In addition, we highlight a difference in the supply-demand relationship for freight transportation that causes additional challenges for decarbonizing that sector. Finally, we emphasize that fleet ownership is key to ensuring timely vehicle fleet turnover as safer and more efficient technologies enter the market.

It allows individuals to easily adopt the model with appropriate adjustments, hence facilitating the creation of wealth.
Impact of Coronavirus on digital transformation in private sector organisations in developing countries
Authors: Nankoomar Tamanna , Rosemary Quilling
Published: December 2023

The onset of the COVID-19 pandemic has introduced a new phase of company operations. The advent of digital transformation (DT) has fundamentally transformed the global business landscape. Despite the global prevalence of this phenomenon, there is limited understanding of digital transformation (DT) in the context of COVID-19 and its impact on private sector organizations in developing nations. This study investigates the impact of COVID-19 on the process of digital transformation in privately owned companies located in underdeveloped nations. To accomplish this objective, a systematic literature review was conducted following the PRISMA (2020) principles, resulting in a selection of 26 studies. This study employs an inductive methodology, where pertinent topics are identified as they arise from the literature throughout the analysis stage. The technology-organization-environment framework (TOE) was subsequently employed to provide a contextual framework for these issues. The research findings suggest that the presence of resources, both financial and technological, is a crucial determinant in the adoption of digital transformation. The adoption of DT has been significantly influenced by various factors, including the role of governments, competitive forces, security, and other relevant considerations. Although organizations in underdeveloped nations encountered numerous hurdles, it was found that digital transformation progressed rapidly in all areas. Companies underwent substantial transformations to embrace digital transformation (DT), including the use of digital business models to facilitate remote operations and heightened investment in education, skills, and innovative digital tactics. Given the recent emergence of COVID-19, there remain numerous uncertainties regarding the enduring impacts that COVID-19 has had on organizations.
Government interventions in the financial literacy of the law-enforcers
Authors: Malepe Joseph Sedila
Published: December 2023

Financial literacy (FL) is a crucial skill set that police officers must possess, particularly in managing their funds during their tenure in the police force and as they approach retirement from their service. The extent of an individual's FL will directly impact the extent of their financial planning knowledge and budgeting abilities required as a police officer, commencing from the initial stages of their career. The primary objective of this study is to investigate the level of FL within the police force, with a particular emphasis on the factors of financial knowledge, attitude, and behaviour. The study employed a simple random sampling technique to gather data from a sample of 68 law enforcement employees stationed in Vosman and Klipfointein. The data was acquired through survey questionnaires. The data were descriptively analysed using the Statistical Package for the Social Sciences (SPSS). The results of the study suggest that police officers often possess low to moderate levels of FL. However, there is a positive correlation observed between the variables under investigation. The recommendation proposes that the government should implement ongoing training and short-term interventions focused on FL, with a particular emphasis on tailoring these initiatives to individuals' income levels and lifestyles. This study utilized intervention and transformational learning theory to support law enforcement professionals in enhancing their financial planning both prior to and following their employment, by means of financial education.
The role of accounting officers in ensuring responsible public financial management
Authors: Makhanya Njabulo
Published: December 2023

The delivery of public services in South Africa is dependent on good governance and decisive leadership. Furthermore, the success of government programmes depends on the size of the budget that has been allocated to a given government department or entity. When the Minister of Finance delivers the budget speech in the National Assembly, there is a clear indication on how much is going to be allocated to each government department over the next financial year. It is up to the government departments to ensure that the allocated budget is used as efficiently and effectively as possible. Each government department is guided by the Public Financial Management Act (PFMA), 1999. The PFMA seeks to regulate financial management in the national government and provincial governments; to ensure that all revenue, expenditure, assets and liabilities of those governments are managed efficiently and effectively; to provide for the responsibilities of persons entrusted with financial management in those governments; and to provide for matters connected therewith. Given the objectives of the PFMA, accounting officers are tasked with the responsibility of enforcing the PFMA in all procurement processes. According to Section 36 of the PFMA, an accounting officer is the head of a department. These accounting officers play an important role in ensuring that services are delivered, while they must ensure that public funds are spent responsibly and in accordance with the relevant government policies and the PFMA. This paper analyses the role that accounting officers need to play in ensuring responsible public financial management, especially because of the limited resources available to our government. By employing a qualitative study, this paper looks at instances where accounting officers did not act in accordance with the PFMA and the implications of this failure.

There is scant literature available in South Africa that explores the knowledge, attitudes and perceptions of student nursing trainees and other healthcare workers who deliver sexual health services to sexual and gender minority (SGM) communities with unique health needs. An online, mixed-method, questionnaire-based survey was employed to conveniently sample 39/78 (50%) final-year Bachelor of Nursing students from the University of Kwa-Zulu Natal to understand their knowledge, attitudes and perceptions. Descriptive statistics were applied for quantitative results and thematic analysis was used for free-text qualitative data. Results suggested that over 67% of the participants lack the skills and knowledge to obtain a comprehensive history salient to the health needs of SGM populations. Students reported that social upbringing and religious beliefs impact the care they render, with many showing favourable attitudes toward the SGM community. Overall, students reported no content related to SGMs in the current nursing curriculum, however, students were receptive, highlighting the need to be clinically competent to provide relevant healthcare for SGM to meet their sexual health needs. It thus require that students must be trained and have included the SGM content in their curriculum to meet the sexual health needs of SGM population to enable non discriminatory, equitable health provision. being informed and having the necessary skills and knowledge obtained during training in the health institutions of higher learning can address the issues of greatest concern related to the HIV health needs of SGM populations.
Public trust deficit in democratic state and political institutions: Ominous Signposts for South Africa
Authors: Tsheola Johannes , Sebola Mokoko Piet
Published: December 2023

This paper uses politico-social capital theorisation of the relationship between public trust and democracy in order to demonstrate the interdependence of the African National Congress’ (ANC’s) declining electoral fortunes and the increasing public trust deficits in South Africa’s state, constitutional democracy and political institutions. As desktop-based research, the paper conducts literature survey to distils the relationship between public trust, as social capital, in institutions of society, and electoral performance and formation of societal leadership vacuum, within complexities of the political-economy and political culture and system such as those entrenched in South Africa under the ANC’s 28-year rule. The paper analyses statistical evidence from Afrobarometer’s 2022 survey about South Africans’ public trust in state and political institutions from 2006 to 2021, as well as national, provincial and local government election results from the Independent Electoral Commission of South Africa (IEC) from 1994 to 2019, to corroborate its theoretical framing. It makes three findings, thus: there is a direct relationship between the ANC’s declining electoral fortunes and the erosion of public trust in institutions of society; the ANC’s 28-years of state governance has created an ominous societal leadership vacuum, setting South Africa’s democracy on the precipice of civil strife; and, the ANC’s declining electoral fortunes will persist into the foreseeable future because public trust is hard to regain and sustain once eroded.

Authors: Strelkovskaya Irina , Onatskiy Oleksiy , Yona Larysa
Published: December 2023

Background. To ensure the protection of the biometric access control system used in unsecured communication channels, it is necessary to exclude the storage and transfer, transfer of biometric data as well as sequences generated on their basis. The paper proposes a cryptographic protocol of two-factor authentication with the zero-knowledge over the extended field GF(2m) on elliptic curves using biometric data and the private key of the user.

Objective. The aim of the article is to develop a cryptographic protocol for zero-knowledge two-factor authentication based on elliptic curves using biometric data and the user’s private key, which allows increasing cryptographic strength and reducing the duration of the authentication process.

Methods. The process of implementing zero-knowledge proof protocols is as follows: one user (proofer) can convince another user (verifier) that he has some secret without disclosing the secret itself.

Results. A cryptographic protocol for two-factor authentication with zero-knowledge over the extended field GF(2m) of elliptic curves using user biometric data is proposed, which significantly reduces the size of the protocol parameters and increases cryptographic strength (computational complexity of the breaking). There is no leakage of private key information and biometric data of the user during the execution of the zero-knowledge proof protocol.

Conclusions. The implementation of a cryptographic protocol with zero-knowledge proof two-factor authentication based on elliptic curves allows significantly reducing the size of protocol parameters and increasing the cryptographic strength (computational complexity of the breaking).
MINIMIZING HIGH-FREQUENCY SWITCHING LOSSES IN WIDEBAND GAN HEMTS FOR FLYBACK CONVERTERS
Authors: Arseniuk Dmytro , Zinkovskyi Yuri
Published: December 2023

Background. In the realm of pulse power supplies, flyback converters play a pivotal role in efficient voltage conversion and providing electrical isolation. Typically, these converters utilize silicon transistors. However, they encounter several issues that hinder their energy efficiency and operational stability. A primary concern is the increase in switching losses at high frequencies. This is attributed to the lower switching speed and higher on-state resistance characteristic of silicon transistors. Such inefficiency leads to substantial power dissipation, thereby reducing overall efficiency. Additionally, the heat generated from these losses necessitates complex temperature control systems, increasing operational burden and affecting the reliability and longevity of the converters. Furthermore, the operational frequency of these converters is limited. While operating at higher frequencies is beneficial for reducing the size of passive components, it exacerbates the problems of switching losses and heat dissipation in silicon transistors.

Objective. This article aims to conduct a comprehensive study and optimization of flyback converters based on High Electron Mobility Transistors (HEMT) made of Gallium Nitride (GaN), focusing on minimizing losses in high-frequency switching. The study delves into the intrinsic properties of GaN HEMTs, highlighting their superior characteristics compared to traditional silicon counterparts, and emphasizes the circuit design methods for minimizing losses and their features.

Method. The research involved a detailed analysis of the switching losses of GaN HEMTs under high-frequency switching conditions. Using computer simulation models, the study examines the impact of various parameters, such as currents and voltages on the GaN transistor, power dissipation, and the output characteristics of the device with different circuit topologies on the performance and efficiency of switching.

Results. The results provide insights into the optimization strategies of topology, particularly the use of transistor gate drivers and snubber circuits, which are crucial for enhancing the overall efficiency and reliability of flyback converters.

Conclusions. The article offers an in-depth analysis into optimizing high-frequency flyback converters using GaN HEMTs, providing valuable guidance for devices requiring compact power sources, such as in small aircraft systems and telecommunications networks.
Extremals in the Markov – Dubins Problem with Control on a Triangle
Authors:   Ailamazyan Program Systems Institute, Russian Academy of Sciences, Ardentov A. A.
Published: December 2023

We formulate a time-optimal problem for a differential drive robot with bounded positive velocities of the driving wheels. This problem is equivalent to a generalization of the classical Markov – Dubins problem with an extended domain of control. We classify all extremal controls via the Pontryagin maximum principle. Some optimality conditions are obtained; therefore, the optimal synthesis is reduced to the enumeration of a finite number of possible solutions.

Phthalate esters (PAEs), a group of chemical compounds, are extensively used as additives in plastics. The objective of this study was to determine how much of a few target PAEs have leached into various samples of drinking water packaged in PET bottles in Effurun, Delta State, Nigeria as well as how ambient temperature, sunshine exposure, and cold storage conditions have affected the concentration of PAE. The concentrations of Di-ethyl-phthalate (DEP), di-butyl-phthalates (DBP), benzyl-butyl-phthalate (BBP), di-n-octyl phthalate (DnOP), and Bis-(2-ethyl-hexyl) phthalate (DEHP) were determined in bottled water samples. The concentrations of PAEs were determined using a gas chromatography coupled with a mass sepctroscopy analyzer (GC-MS). Phthalate compound was observed to be in all bottled water placed under different storage conditions; cold storage (CW), ambient storage (AW), and sunlight storage (SLW) for a period of 2, 4, 8, 12 and 16 weeks. However, the greatest leaching effect was observed in PET bottled water placed sunlight conditions for sixteen weeks with concentrations of; DEHP (2.1-11.2) µg/L, DEP (0.98-3.87) µg/L, DBP (2.98-13.8) µg/L. The results from this study indicated that, under various storage conditions, DEP, DBP and DEHP from PET bottles may leach more into the drinking water over a period of time under different storage conditions. The result additionally gave indication that DEHP; a known endocrine disruptor, with anti-androgenic and possible human carcinogen effects, exceeded the 6 µg/L USEPA Maximum Contamination Level (MCL) in drinking water, and also greater than 8 µg/L which is the indicated MCL by the World Health Organization (WHO).

A ENTONAÇÃO VALORATIVA NA CONSTITUIÇÃO DE SENTIDOS NO ENSINO DA LÍNGUA PORTUGUESA EM MOÇAMBIQUE
Authors: Manuel Arcedes José
Published: December 2023

Este artigo é resultado do recorte do trabalho de conclusão de curso intitulado “A Entonação Valorativa nos Géneros Discursivos do Livro Didáctico de Portuguesa do Ensino Primário em Moçambique.” Sendo assim, neste artigo procuramos discutir à luz dos pressupostos do dialogismo, como a entonação valorativa, enquanto conceito axiológico auxilia no processo de ensino e aprendizagem da leitura. Como recurso metodológico, partimos pelo uso da técnica denominada análise de conteúdo (AC), baseada na perspectiva da análise dialógica do discurso (ADD). Assim, os resultados desta pesquisa aduzem que a entonação valorativa enquanto conceito axiológico é fundamental na formação da atitude responsiva do aluno, bem como ajuda na formação do aluno-leitor activo. Portanto, a pesquisa demostrou que o conhecimento do professor destes elementos é bastante importante, uma vez que permite que o aluno na condição de aprendente possa reflectir e relacionar os géneros discursivos apresentados com situações reais do seu mundo. Por isso, este artigo sustenta-se em dois princípios essenciais. O primeiro refere-se ao argumento defendido pelo Círculo de Bakhtin, de que a linguagem se constitui na interacção entre os sujeitos, a considerar a posição ocupada por eles, dentro de um determinado tempo e espaço. O segundo, ao próprio processo de didatização dos géneros discursivos, visto que, ao serem disponibilizados nos livros didácticos, pensamos que podem concretizar a linguagem nas enunciações em sala de aula, o que implica constatar que os géneros são firmados nesse instrumento de ensino como a mais pura manifestação da linguagem em sociedade.

Published: December 2023

O presente artigo analisa algumas representações do gênero feminino em Grande Sertão: Veredas. O objetivo é mostrar, por meio dos conflitos representados ao longo da narrativa, quais são os papéis desempenhados por Diadorim, Nhorinhá e Otacília, e como é a recepção destes papéis por Riobaldo, personagem central da obra. Em um ambiente marcado pela submissão da mulher, a personagem que empreende uma performance de submissão, sagra-se a escolhida por Riobaldo. Às outras, transgressoras em sua performance, resta a morte ou o abandono.
PECADORA INOCENTE

Published: December 2023

O artigo propõe discutir e conceituar “Pecadora Inocente”. Para tanto, parte-se de um olhar que percebe determinadas personagens femininas de Guimarães Rosa. Início observa-se personagens que traem seus maridos e amantes: Lívilia de “Desenredo”, Silivania de “Duelo” e Luiza de “Sarapalha”. O segundo é composto por a Destemida de “Estas estórias”, Flausina “Esses Lopes”, Mula Marmela de “A benfazeja”, que vão assassinar ou provocar assassinatos de homens. Em todas essas narrativas as mulheres conseguem sobreviver a todos as imposições que lhes eram impostas, quer por um casamento malsucedido, quer por homens valentes.
PAISAGEM TRANSFIGURADA
Authors: Bruch Deitos Miguel
Published: December 2023

Grande Sertão: Veredas (1956) originou outra obra literária de nome homônimo: uma minissérie televisiva. Assim, busco compreender como a nova mídia elaborada a partir de configurações próprias, interage com o texto da obra original facultada aos limites do que é popularmente conhecido como "adaptação". A partir da tradução intersemiótica abarco como o “sertão” se manifesta enquanto paisagem e a relação com o mito de Fausto na obra. A análise delimita-se às figurações do momento narrativo em que Riobaldo exclama o nome do demônio nas "Veredas-Mortas”. Finalmente, resulta evidenciada as relações formais que constituem a subjetividade do personagem em cada obra.
