Authors: Raheem Ali Hussein , Ashraa Kalee Hassan Habib Hassan
Published: January 2024

Adoption of graded and certified seeds for planting has a high demand among the farmers at Kirkuk city, where maize has different way of consumption like a staple food, forge crop and raw material for industry. This study aimed to evaluate common domestic maize genotype, against the modern maize genotype under different summer planting times at the district of Kirkuk - Kirkuk governorate, Iraq. The study include two genotypes of maize, (Bohoth106 modern genotype and domestic maize genotype) and three planting times (early-July, mid-July and late-July). The experiment was established in three replicate blocks under randomized complete block design. The results showed that Bohoth106 which planted at mid-July had a significant performance, in traits kernels weight per ear (164.5 g), grain yield (11.2 t.ha-1), Stover yield (25.1 t.ha-1) and biomass yield (36.2 t.ha-1). Whereas, the lowest values were observed in the interaction between domestic maize with early-July planting time. Simple correlation coefficients revealed that grain yield positively and significantly correlated with leaf area index, Stover yield, biomass yield, grain Stover ratio and harvest index. According to the presented results farmers can cultivate Bohoth106 at mid-July till late-July to achieve high grain yield during summer planting time in Kirkuk district, Iraq. Keywords: Maize yield, Genotypes, Planting times, Regression relationship.

Formulation and Evaluation of Phytosomes of Pterocarpus santalinus Extract
Authors: Dhadse Pooja
Published: January 2024

Abstract: Novel drug delivery system (NDDS) phytosomes were prepared by complexing phospholipids: Cholesterol and Leaves extract of Pterocarpus santalinus can act as molecular adhesive to bind components together. Their ability to penetrate lipid-rich biomembranes and shield the essential components of the herbal extract from being destroyed by digestive secretions and gut bacteria increases bioavailability. The bioavailability of the herbal formulation is increased by phytosomes' ability to distribute the standardised plant extracts and phytoconstituents through different routes of drug administration methods. The present study directed toward the development and evaluation of phytosomes of Pterocarpus santalinus. Through an in-vitro dissolution study, the produced complex's physicochemical characteristics were examined. The outcome demonstrated that there was no formation of a novel chemical between the hydroalcoholic extract and the phospholipids in the Methanolic extract-phospholipid complex. Prepared Pterocarpus santalinus extract phytosomes showed better bioavailability.
KAJIAN TERHADAP ISU PEMBELIAN TANAH WAKAF MENERUSI MEKANISME WAKAF TUNAI DI NEGERI SELANGOR A Study on Issues in Waqf Land Purchasing Through Mechanism of Cash Waqf in Selangor
Authors: Mustapa Siti Salwani , Wahid Hairunnizam , Ibrahim Mohd Faisol
Published: January 2024

The practice of waqf is vital in the development of the entire Muslim community. The waqf system at the Perbadanan Wakaf Selangor (PWS) has expanded in various ways or methods to include cash waqf, general waqf and special waqf, therefore providing Muslims with the opportunity to perform worship in a collective manner in order to enhance the Muslim community’s socio-economic status. This study was conducted to understand the concept of land purchase using cash waqf in the state of Selangor. The objective of this study is to ascertain the current status of waqf for the purchase of land through the cash waqf mechanism, along with issues in implementing it. This study used both the library study method and a field study to collect qualitative data. Data for this study was also obtained from semi-structural interviews with PWS officers and those involved in the management of waqf property. The findings show that waqf for land purchase within the state of Selangor has achieved its objective, despite challenges faced. The constraints regarding the waqf system are that the waqf fund collection had not achieved its target in addition to the short contract durations, which had caused the development of the planned waqf property to not run smoothly. Several recommendations and policy implications are suggested to ease future purchases of land through the cash waqf scheme so that it will become a valuable asset used for Muslims’ economic development.

Authors: D Olanda Ferrando Magnus , Do Nascimento Lock Fernando
Published: January 2024

A utilização de pregão eletrônico nas aquisições de medicamentos em hospitais públicos é um processo que impacta todas as demais atividades e sua reformulação deve ser constantemente estimulada com o desenvolvimento de novas técnicas. Logo, o trabalho tem por objetivo abordar as dimensões da transação, sob os aspectos da Teoria dos Custos de Transação (TCT), nos processos de pregão eletrônico para aquisição de medicamentos de um Hospital Público Federal. Trata-se de uma pesquisa exploratória com abordagem qualitativa na modalidade de um estudo de caso, com aplicação de entrevistas, observação in loco e pesquisa documental. Os resultados apontaram que as dimensões interagem entre si e influenciam os resultados dos processos licitatórios de pregão eletrônico do hospital público federal gerando impactos de superdimensionamento das previsões de medicamentos e excessivo número de cancelamentos de itens, sugerindo que uma demanda especial na abordagem desse tipo de aquisição pode minimizar a influência dos custos de transação e, consequentemente, reduzir custos.

Authors: Wilczyński Artur
Published: January 2024

Artykuł prezentuje badania nad sytuacją ekonomiczną wielkoobszarowych gospodarstw roślinnych położonych na terenie trzech województw: mazowieckiego, wielkopolskiego oraz zachodniopomorskiego. W analizowanych gospodarstwach wdrożono trzy scenariusze różniące się między sobą cenami na środki do produkcji rolnej, produkty rolne oraz wielkością wsparcia gospodarstw ze środków unijnych. Otrzymane wyniki wskazują, że zdecydowana większość gospodarstw w 2014 roku będzie charakteryzować się wyższymi przychodami niż w 2006 roku. Ze względu na wzrost kosztów produkcji tylko w scenariuszu optymistycznym nastąpi zwiększenie dochodowości badanych gospodarstw w porównaniu do roku wyjściowego. W przypadku scenariusza najbardziej prawdopodobnego dochód rolniczy netto tylko w gospodarstwach mazowieckich i zachodniopomorskich będzie wyższy niż w 2006 roku.

Szanse i ograniczenia dzierżawy gruntów rolnych w Polsce
Authors: Jarka Sławomir
Published: January 2024

Dzierżawy w Polsce mają długoletnią tradycję, ale dotychczas skala tego zjawiska nigdy nie była wysoka i do niedawna często nie wykraczała poza nieformalne umowy zawierane na ogół ustnie. Na zmianę podejścia w traktowaniu dzierżaw, ich uatrakcyjnienie w odbiorze producentów rolnych wpłynęły przede wszystkim uwarunkowania ekonomiczne, takie jak zaprzestanie działalności przez część jednostek oraz rosnące ceny gruntów, zwłaszcza po wstąpieniu Polski do UE.

Authors: Daniłowska Alina
Published: January 2024

Celem opracowania jest określenie, w jaki sposób banki spółdzielcze oraz rolnicy starają się przezwyciężyć problemy wywołane asymetrią informacyjną na rynku kredytów rolniczych. Materiały empiryczne do badań pochodzą z przeprowadzonych wśród prezesów banków spółdzielczych badań ankietowych. Wyniki badań wskazują, że rolnicy stanowili najwyżej ocenianą pod względem solidności grupę klientów banków spółdzielczych. Za. banki w ocenie wiarygodności kredytowej rolników wykorzystywały między innymi historię kredytową rolnika aczkolwiek nie znalazła się ona wśród trzech najważniejszych czynników decydujących o przyznaniu kredytu. Ze strony rolników jako narzędzie sygnalizowania swojej postawy wobec różnego rodzaju zobowiązań, w tym kredytowych może być stosowana reputacja. W zdecydowanej większości badanych banków brano ją pod uwagę przy rozpatrywaniu wniosków kredytowych.

Published: January 2024

Background/Aim. Since finding a safe and efficient strategy of multimodal postoperative analgesia and sedation is particularly critical, it is important that dexmedetomidine (DM) combined with opioid anesthetics can enhance that through a synergistic action. The aim of the study was to assess the effect of butorphanol tartrate (BT) combined with DM on postoperative analgesia. Methods. A total of 100 elderly patients undergoing general anesthesia surgery from January 2019 to June 2022 were selected. The patients were divided into two equal groups ? research group (RG) and control group (CG), using the random number table method. All patients were given postoperative patient-controlled intravenous analgesia (PCIA) plus background infusion. CG patients were given 10 mg of BT, and RG patients were given 10 mg of BT and 300 ?g of DM. The analgesics were diluted in 100 mL of 0.9% normal saline. The doses of rescue analgesic tramadol within 48 hrs after surgery, the number of PCIA boluses 48 hrs after surgery, and postoperative hospitalization time were recorded. The Visual Analog Scale (VAS) score, Ramsay sedation score (RSS), inflammatory and stress responses [interleukin (IL)-6, interferon (IFN)-?, and angiotensin II (Ang-II)], and anesthesia-related adverse reactions (ARAR) were compared at different time points. Results. The dose of tramadol within 48 hrs after surgery, the number of PCIA boluses 48 hrs after surgery, and the postoperative hospitalization time of RG were lower than those of CG (p < 0.05). VAS scores at rest and during activity and serum IL-6, IFN-?, and Ang-II levels of both groups increased at 4 and 12 hrs after surgery, then decreased at 24 hrs after surgery. The above indicators of RG were lower than those of CG at each time point (p < 0.05). The RSSs of the two groups increased at 4, 12, and 24 hrs after surgery, then dropped at 48 hrs after surgery. The scores of RG were lower than those of CG at each time point (p < 0.05). The incidence rates of ARAR had no significant difference between RG and CG (p > 0.05). Conclusion. BT combined with DM is effective for analgesia and sedation after general anesthesia surgery in elderly patients, which can reduce inflammatory and stress responses without increasing ARAR.
Evaluating the Commensurate with Income Standard
Authors: Sansing Richard C.
Published: January 2024

This study analyzes a model in which intellectual property (IP) that generates uncertain future cash flows is sold by a U.S. parent to a foreign subsidiary. The parent has private, imperfect information regarding the value of the IP. The study compares the firm’s expected tax and penalty payments under the commensurate with income (CWI) standard to the payments under the fair value method, in which the transfer price is the expected value of the IP using all the facts publicly available after the value is realized. It compares payments under both methods to the payments using the fair private price, which is the value of the IP on the date of sale given the parent’s private information. Expected tax and penalty payments using the fair private price are strictly less than expected payments under the CWI standard and are strictly greater than expected payments under the fair value method.

How Do Online Conflict Disclosures Support Enforcement? Evidence from Personal Financial Disclosures and Public Corruption
Authors: Scherf Alexandra A.
Published: January 2024

Public corruption is a concern for democracies around the world. In the U.S., states have responded to this issue by publishing personal financial disclosures (PFDs) for public officials online. PFDs are a conflict-of-interest disclosure designed to relieve agency conflicts between private citizens and government officials by documenting overlaps between officials’ financial interests and public responsibilities. This paper explores whether and how online PFD supports anticorruption enforcement. I present a stylized model illustrating how online PFD leads investigators to increase case referral volume and quality. Empirically, I find that online PFD for local officials is associated with increased referral rates and greater likelihoods of prosecution conditional on referral. I conduct 126 field interviews of federal prosecutors, journalists, and ethics commissions to understand the mechanisms behind these results. I conclude that online PFD supports the enforcement of local corruption by reducing disclosure acquisition costs for enforcement agents.

Authors:   University of San Diego, Ceballos Luis , Christensen Jens H. E. ,   Federal Reserve Bank of San Francisco, Romero Damian ,   Banco Central de Chile
Published: January 2024

We provide market-based estimates of the natural real rate, that is, the steady-state short-term real interest rate, for Brazil, Chile, and Mexico. Our approach uses a dynamic term structure finance model estimated directly on the prices of individual inflation indexed bonds with adjustments for bond-specific liquidity and real term premia. First, we find that inflation-indexed bond liquidity premia in all three countries are sizable with significant variation. Second, we find large differences in their estimated equilibrium real rates: Brazil’s is large and volatile, Mexico’s is stable but elevated, while Chile’s is low and has fallen persistently. Although uncertain, our estimates could have important implications for the conduct of monetary policy in these three countries.

Published: January 2024

The article explores the concept of a free economic zone. It is determined that the concept of a free economic zone is not formally updated, but in a collective understanding it is actively used by many specialists in practical circulation. The authors give arguments about the functioning of a free economic zone in Russia and analyze the general position of such zones in the world. The experience and practice of the functioning of free economic zones in the country are diligently monitored, but the main monitoring is concentrated at the Ministry of Economic Development of Russia, whose reports provide positive indicators. The article discusses a cross–section of reporting data reflecting only the functionality of territorial development zones, territories of advanced socio–economic development, special economic zones. Based on a sample of reporting data and discussion of the opinions of various experts, the authors present possible variations of the expansion of the types of free economic zones. In particular, it is proposed to consider options related to meeting the needs of socially low7income citizens, pensioners and other categories of persons in need of assistance and support from the state and society. Thus, it is essential to update the concept of «free economic zone» at the legislative level and to form a unified legal message of the types of such zones.

At the present stage of economic development of Russian entrepreneurship, the most important task is the formation of directions for making competent and timely management decisions for further improvement of the management of financial, economic and organizational activities of organizations and the development of competitive advantages in the market.

The constantly occurring changes in the socio-economic relations of the country, taking into account the policy of the state, the dynamics in consumer demand and market conditions, require economic entities to create an adequate enterprise management system based on managerial decision-making. The decisions themselves, of course, are the result of financial analysis, balanced conclusions and action plans, since they are designed to optimize various aspects of the activities of economic entities.
Security and Peace Discourse Through Peace Media and Its Contribution to Peace in Aceh After the Helsinki Memorandum of Understanding
Authors: Sugito Sugito , Sukmono Filosa Gita
Published: January 2024

Attitude is a significant factor in the formation of violent conflict. Therefore, efforts to change hostile attitudes into peaceful ones are vital to the success of peacebuilding in countries emerging from conflict. Peace media has become an important weapon for influencing people's opinions in order to remove the cultural violence that has gotten entrenched during the conflict and replace it with a culture of peace. Using securitization theory, the purpose of this study is to explain how peace media utilized desecuritization to turn warring sentiments into peace attitudes in Aceh following the 2005 Helsinki Memorandum of Understanding (MoU) promoting peace. This study reveals that Tribune Aceh, Kompas, and Republika have emerged as key participants in the desecuritization of the Aceh conflict, allowing them to promote a peaceful mindset among the public. Despite the difficulties associated with the Helsinki MoU's implementation, the completion of this desecuritization eventually contributed to the development of permanent peace in Aceh.
Metáfora, sus funciones y características en Moneda de tres caras de Francisco Hernández
Authors:   , Dadaeva Alina
Published: January 2024

La presente investigación ofrece un análisis integral de la metáfora en el libro Moneda de tres caras de Francisco Hernández. Hoy en día la metáfora se percibe no sólo como una figura retórica, cuya principal función consiste en embellecer el discurso e incrementar su fuerza expresiva, sino como una herramienta cognitiva que predefine nuestra forma de percibir la realidad. Por lo tanto, el análisis de las metáforas en los tres poemarios que conforman el libro permite comprender cómo se manifiesta a nivel lingüístico la visión del mundo del autor, sus creencias e ideales. El trabajo estudia las funciones semánticas de dicho tropo, en particular, establece relaciones entre la metáfora y el tema de la locura como el motivo central del libro, el pensamiento mitopoético del autor y algunas nociones propias a la poesía de la época posmoderna, tales como la oposición al mundo capitalista y el desvanecimiento del yo lírico. Asimismo, el trabajo analiza los tipos de las metáforas más recurrentes en correlación con las preocupaciones estéticas del poeta, así como sus principios de la construcción metafórica, en específico, los métodos de la desautomatización de símbolos arquetípicos y metáforas comunes. De esta manera, la investigación permite, por un lado, entender mejor el sistema de ideas de Moneda de tres caras, y, por el otro, acercarse a la comprensión de la técnica poética de Francisco Hernández.

This article presents an analysis of genotype and phenotype correlations in a pediatric cohort with Langerhans cell histiocytosis (LCH). Approximately 60% of LCH patients carry BRAF V600E somatic point mutation. Numerous studies have demonstrated that the presence of this mutation is associated with a more severe course of the disease and a higher risk of relapse. Apart from BRAF V600E mutation, other mutations in genes involved in the RAS/RAF/MEK/ERK signaling pathway have been identified in LCH. Next generation sequencing of DNA with high coverage of target regions is considered an optimal approach to detect somatic mutations other than BRAF V600E. The identification of somatic driver mutations holds great potential for enhancing our understanding of the phenotypic heterogeneity of LCH and developing targeted therapeutic strategies. The study was approved by the Independent Ethics Committee and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology.

The achievement of remission at the end of induction (EOI) chemotherapy in patients with acute lymphoblastic leukemia (ALL) is the key parameter of treatment effectiveness evaluation. The aim of the study – defining complete remission by multicolor flow cytometry (MFC) and bone marrow (BM) cytomorphology (CM) at the EOI chemotherapy in children with B-lineage ALL. The study was approved by the Independent Ethics Committee and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology. The study included patients of “ALL-MB 2008” and “ALL-MB 2015” trials for whom minimal residual disease (MRD) was evaluated by MFC at the EOI simultaneously with CM BM investigation. Less than 5% blasts in BM and MRD < 1% were established as the remission achievement criteria for CM and MFC respectively. The study group included 1498 children aged from 1 to 18 years (median age was 4 years and 11 months) with B-cell precursor ALL. The overall concordance of MFC and CM was found to be 96.1% (1440 of 1498 patients). In 36 (2.4%) children with MRD ≥ 1%, M1 BM status was observed. In contrast, in 22 (1.5%) patients with M2/M3 BM status by CM, MRD value was below 1%. Treatment outcome was analyzed in 522 patients of “ALL-MB 2008” trial. Children with M2/M3 BM, as well as with MRD ≥ 1% demonstrated dramatically inferior outcome, in comparison to those who achieved remission. The presence of at least one of the mentioned criteria (M2/M3 status by CM or MRD ≥ 1% by MFC) defined a group of 23 (4.4%) patients with very low event-free survival (34.9%, standard error 11.0%) and very high cumulative incidence of relapse (56.4%, standard error 12.0%). For the evaluation of remission achievement, MFC and CM should be applied simultaneously at the EOI. High leukemic burden found by any of these methods is the clear definition of induction failure. MRD detection at the EOI should be implemented in any modern treatment protocol as an obligatory stage of treatment response monitoring and final risk group stratification. Considering the crucial importance of the MRD detection results, this study must be performed only in the reference laboratories of the study groups.

Published: January 2024

The combustion chamber is a crucial component in power generation within a micro gas turbine. This paper prioritizes practical over theoretical considerations in designing an efficient, small-scale combustion chamber for micro gas turbine applications. The investigation covers the temperature profile within the combustion chamber, employing 19 reversible reactions and considering 9 different chemical species in reactive flow calculations. Preliminary experiments demonstrate hydrogen as a feasible fuel in a micro combustion chamber, generating approximately 1 kW of thermal power. Turbulence physics are assessed using the accurate k-Ɛ model. Findings indicate a reactant inlet temperature of 300 K and a primary zone temperature of 1750 K. This research suggests that minimizing the back pressure effect in a steady-state micro combustion chamber can improve turbine performance.
High-performance functional materials based on polymer nanocomposites—A review
Authors: Krishnan Mohan Raj , Alsharaeh Edreese Housni
Published: January 2024

Oil spill clean-up is a long-standing challenge for researchers to prevent serious environmental pollution. A new kind of oil-absorbent based on silicon-containing polymers (e.g., poly(dimethylsiloxane) (PDMS)) with high absorption capacity and excellent reusability was prepared and used for oil-water separation. The PDMS-based oil absorbents have highly interconnected pores with swellable skeletons, combining the advantages of porous materials and gels. On the other hand, polymer/silica composites have been extensively studied as high-performance functional coatings since, as an organic/inorganic composite material, they are expected to combine polymer flexibility and ease of processing with mechanical properties. Polymer composites with increased impact resistance and tensile strength without decreasing the flexibility of the polymer matrix can be achieved by incorporating silica nanoparticles, nanosand, or sand particles into the polymeric matrices. Therefore, polymer/silica composites have attracted great interest in many industries. Some potential applications, including high-performance coatings, electronics and optical applications, membranes, sensors, materials for metal uptake, etc., were comprehensively reviewed. In the first part of the review, we will cover the recent progress of oil absorbents based on silicon-containing polymers (PDMS). In the later details of the review, we will discuss the recent developments of functional materials based on polymer/silica composites, sand, and nanosand systems.

The structure of a resonator, based on a series connection of a planar inductor and a lumped capacitor, is expanded using an additional capacitor with a MOSFET transistor. Due to the presence of the controllable active element, it is possible to dynamically change the phase of the current flowing through a meta-cell and shift a frequency response within an assumed range. Since the transistor is driven by the unipolar square wave with a changeable duty cycle and time delay, two closed-loop controllers were utilized to achieve a smart material, able to automatically attain and maintain the imposed resonant frequency. As a result, the complex effective magnetic permeability of the metamaterial can be smoothly changed, during its operation, via an electrical signal, i.e. by adjusting the parameters of a control signal of the active element. The design of the meta-cell, as well as the measuring, data operation and control part, are presented in detail. An illustrative system is examined in terms of achieving the user-defined resonance point of the metamaterial. Transient responses with estimated settling times and steady-state errors and the effective permeability characteristics for the exemplary cases are shown. The meta-cell is also tested experimentally to validate the theoretically determined effective properties.

This study aims to evaluate the effectiveness of machine learning (ML) models in predicting concrete damage using electromechanical impedance (EMI) data. From numerous experimental evidence, the damaged mortar sample with surface-mounted piezoelectric (PZT) material connected to the EMI response was assessed. This work involved the different ML models to identify the accurate model for concrete damage detection using EMI data. Each model has been evaluated with evaluation metrics with the prediction/true class and each class is classified into three levels for testing and trained data. Experimental findings indicate that as damage to the structure increases, the responsiveness of PZT decreases. Therefore, examined the ability of ML models trained on existing experimental data to predict concrete damage using the EMI data. The current work successfully identified the approximately close ML models for predicting damage detection in mortar samples. The proposed ML models not only streamline the identification of key input parameters with models but also offer cost-saving benefits by reducing the need for multiple trials in experiments. Lastly, the results demonstrate the capability of the model to produce precise predictions.

Authors: Cavero-Retuerto Araceli Milagros , Cucho-Flores Robert Richard , Ilizarbe Gliria Susana Mendez , Tejada-Estrada Roberto Justo , Garro-Aburto Silvia Filomena
Published: January 2024

Purpose: In order to contrast the trends in the literature regarding the subject of communication skills in higher-level students, main themes were identified that were emphasized before the pandemic and that, during and after it, ceased to be the subject of discussion.
 
Methods: There was a qualitative approach. It used the narrative documentary review method and Boolean search engines in online indexed databases. From 421 identified articles, 20 were selected for analysis in the "before pandemic" condition and 24 for the "during and post-pandemic" ones, classifying them by type of Intervention and diagnosis and by research focus: qualitative and quantitative.
 
Results and Conclusion: The pre-pandemic studies focused on elucidating the aspects associated with communication skills and academic performance, trying to design tools and implement strategies to improve communication performance in students. Finally, it is expected that educational institutions consider the relevance of implementing plans to reinforce and develop these soft skills in young people, maximizing technological resources as allies in improving their development in this globalized social context.
 
Research implications: On the other hand, in the During and post-pandemic stages, they came together to explain the causes linked to the withdrawal of the expressive ability of the students, reconsidering the use of virtuality and highlighting the need to use traditional strategies as the best alternative to promote communicative skills.
 
Originality/value: Study in the face of the overwhelming irruption of remote education as the only option for academic interaction.
Pamięć o Holokauście w najnowszej prozie słowackiej (na przykładzie powieści Silvestra Lavríka "Niedzielne szachy z Tisą")
Authors: Majerek Rafał
Published: January 2024

The article presents the main problems connected with Silvester Lavrik’s historical novel Niedzielne szachy z Tisą. The book belongs to an important trend in contemporary Slovak literature, addressing the period of the clerofascist Slovak State during the Second World War. In the first part, selected cultural and historical‑literary contexts have been presented, e.g. the issue of reinterpreting the past in the circumstances of freedom after 1989, or the ways of discussing the problems of Holocaust in Slovak literature. The second, interpretive part, is devoted to the narrative strategies implemented in the novel, various attitudes of characters towards the activities preceding the Extermination, demythologizing the figure of the state leader, Josef Tisa, as well as the way of presenting conditions and circumstances which made the tragedy of Slovak Jews possible. It has been pointed out that submission to state authority and ideology led to losing the sense of individual responsibility and justified an active participation in violence acts or assuming the role of passive spectators. The novel’s engaging character and the potential to provoke reflection concerning the attitude of an individual towards contemporary problems and challenges has been regarded as a significant aspect of Lavrik’s novel as a work dedicated to the condition of the community and its value.
„Sztuka dla sztuki” czy „sztuka dla narodu”? Działalność artystyczna, krytycznoliteracka oraz wydawnicza Iwana Trusza wobec wyzwań ukraińskiego życia społecznego w Galicji na przełomie XIX i XX wieku
Authors: Neszew Vira
Published: January 2024

The article is an attempt at reconstructing the artistic and critical literary activity of a Ukrainian painter Iwan Trusz, who noticed a great need of the Ukrainian society to cultivate and develop national art. The Ukrainian artist also contributed to the development of Polish art of that period, as he was highly estimated among Polish intellectuals and took an active part in Polish and Ukrainian cultural enterprises that took place in Lviv at the turn of the 19th and 20th centuries. The experience which Trusz gained during his education in the Cracow Academy of Fine Arts, as well as his direct contact with distinguished Polish painters (e.g. Leon Wyczółkowski, Jan Stanisławski) evoked in the painter a great need to take care of the enrichment of contemporary Ukrainian art and to raise the awareness of Galician Ukrainians about the effect which art has on the formation of every nation. Looking at the activity of Trusz‑an artist or Trusz‑an art critic from the perspective of the 21st century, makes it possible to find the answers to some key questions: “Should national art be promoted?”, “How to educate society through art?” and “What is the role of an artist during the formation of an independent nation?”
Othering as a trait of postcolonial literary discourse (based on the example of French-language literature)
Authors: BYKOVA O. A. , SOKOLOVA V. L.
Published: January 2024

Modern globalization processes are changing not only the geopolitical but also the linguistic map of the world which in turn affects the spread, use of languages and the number of their native speakers. Nowadays Romance languages including French are a cultural part of the identity of the world's majority. They laid and formed the postcolonial matrix of the intercultural dialogue the development of which continues today. Modern linguistic and cultural interactions are implemented within the framework of the opposition "minority-titular culture" thereby forming the interaction of "global" and "local". It is clearly manifested at the junction of the language, the history of a country or region and its socio-cultural aspects. However, it finds a special form of expression in the postcolonial discourse of fiction, which has not only linguistic specificity, but also is a carrier of the ethnocultural code of individual regions and countries. The designated type of discourse has special characteristics, among which we highlight the idea of othering. In this article, we consider the opposite points of view on the interaction of global and local cultures, as well as how it manifests itself through the prism of language, both in cultural-historical and sociolinguistic aspects. The narrative strategies used by the authors in postcolonial discourse allow for a different interpretation of the concept of the "other", the idea of borderline cultures, spatial and temporal perception and ethnospecificity. Based on the analysis of the literature of the Franco-Moroccan writer T. Ben Jellun, whose novel has become the object of research, can conclude that the identity of minority cultures in postcolonial discourse manifests itself through syncretism, hybridity, extralinguistic factors, ideas of indigenization and othering.

This study is about what particular people belong to the particular ethnic have in mind as their ideology to see the environment, reflected from traditional fishing ritual in Acehnese speech community under the eco-linguistic perspective. In addition, with reference to social praxis, ecolinguistics recognizes three dimensions, namely ideological, sociological, and biological dimensions relating to the exploitation of the environment for fishing through ritual speech. The purpose of this study is to determine the ideology reflected in the speech. The study employed a qualitative research methodology, utilizing a phenomenological approach. The study makes use of verbal expressions expressed by naval commanders, gathered through a combination of participatory observation and comprehensive interviews at a central location of fish market and sanctuary in Banda Aceh, Aceh Indonesia. The data collected serve as the basis for the analysis and interpretation of the research findings. The respected ideology was then compared to the concept of ecosophy. The results of the analysis show that the ritual holistically contains the ideology of environmental preservation. The efforts to assist the natural, social, and spiritual preservations, specifically in marine environments, are obviously detected in the discourse. The ideology offered is in accordance with the concept of ecosophy, which includes beneficial discourse. However, part of the utterances also reflect the ambivalent discourse, but not the destructive one.
