Pengelolaan Sumber Daya berbasis Komunitas: Potret Penyediaan Listrik Berbasis Masyarakat di Desa Andung Biru, Kabupaten Probolinggo
Authors: Budiono Mohammad Farid , Susetiawan
Published: January 2024

Pengelolaan energi terbarukan oleh masyarakat sering kali mengalami kegagalan. Berbagai faktor menjadi sebab, mulai dari pengelolaan yang rumit, memerlukan modal besar, hingga tantangan persaingan bisnis dengan sumber energi lainnya. Fakta tersebut menjadi dorongan studi ini untuk mengulas praktik baik sebuah pengelolaan listrik berbasis energi terbarukan atau kemudian disebut dengan Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) yang eksis dan tetap berlanjut dari tahun 1993 hingga sekarang. Melalui pendekatan penelitian kualitatif, studi ini setidaknya mengungkap bahwa keberlanjutan tersebut dikarenakan terdapat beberapa proses pengelolaan yang saling berkaitan satu dengan yang lain. Pertama, PLTMH diawali dengan munculnya ide dari seorang penduduk lokal. Kedua, penemuan ide tersebut diaplikasikan dengan membangun PLTMH yang dalam perjalanannya melibatkan berbagai aktor dari dalam dan luar desa. Ketiga, pengelolaan organisasi tercermin dari dikelolanya PLTMH tersebut secara bersama-sama oleh Kelompok Tirta Pijar. Terakhir, masyarakat merespons dengan manfaat yang diterima seperti perubahan kondisi yang dialami dan keunggulan PLTMH.

Abstract

The process of renewable energy by communities often experiences failures. Various factors contribute to this, such as from complex management, requiring substantial capital, to business competition challenges with other energy sources. These facts serve as the caused for this study to showing the best practices of renewable energy-based electricity management, specifically referred to as Micro Hydro Power Plants (PLTMH), which have been in existence and ongoing since 1993. Through a qualitative research approach, this study reveals that sustainability is due to several interconnected management processes. Firstly, PLTMH begins with the emergence of an idea from a local actor. Secondly, the implementation of this idea involves building PLTMH, which engages various actors from within and outside the village. Thirdly, organizational management is reflected in the collective management of PLTMH by the Tirta Pijar Group. Lastly, the community responds with benefits such as changes in their conditions and the advantages of PLTMH..

Authors: V. Jalu M. , Ambaliya P. S. , Modhvadiya Y. H.
Published: January 2024

Insects, diseases and weeds are the three main biological elements that have the greatest influence on agricultural output losses and farmer profits. The two most crucial practises in agriculture for maximum yielding are chemical application and weeding. In the past, spraying was performed using a knapsack sprayer, and weeding was carried out manually and with a bullock-drawn weeder, both of which required a lot of time and effort. For spraying and weeding in modern agriculture, farmers employ a variety of power-operated tools. However, because each task was carried out independently, it took more time and effort to finish the weeding and spraying tasks. Multioperational equipment or machinery is required to decrease operating time, cost, and the number of passes. As a result, efforts have been made to create a machine that can complete both tasks in a single pass. Considering these points, mini tractor operated sprayer cum weeder was developed. By using the developed sprayer cum weeder time saving of 95.79 %, 90.42 % and 38.71 % could be achieved as compared to existing manual methods, animal drawn machine and power operated machine and developed machine could also save 91.50 and 8.84 % operational cost as compared to existing manual methods and power operated machines in spraying and weeding operations respectively. The weeding efficiency of the developed machine for combined operations was found 84.53 % as compared to power operated weeder (86.12 %) which is more or less equal while it is only for weeding operation.

Published: January 2024

In West Africa, and particularly in Mali, rice is the staple food of the population. However, its production is faced with various constraints, including soils poor on the one hand and difficult access to inputs on the other. Indeed, waste, especially excreta, contains nutrients that are essential for crop development. It is within this framework that this study was conducted to determine the human urine effect on the production of NERICA 4 rice in the Sudano-Sahelian zone. Different urine doses in combination or not with organic fertilizer were put in competition through an experimental design in Ficher Block with eight repetitions. The results after variance analysis showed statistical differences between treatments. The yield increase was most marked with the 111 kg N/ha urine + 5 t organique fumure (T7), which provided the highest rice yield with 1623 kg/ha compared to the mineral fertilizer control (T9) with 1550 kg/ha.The analysis of economic profitability shows that the dose 111kg N/ha urine alone with a ratio of 3.32 is better than the other doses of fertilizers compared to the FAO standard (RVC > 2).
Effect of crossbreeding and dietary neutral detergent fiber (NDF) levels on feed intake, nutrient digestibility, rumen parameters and nitrogen retention of beef cattle
Authors: Binh Truong Nguyen , Van Thu Nguyen
Published: January 2024

This experiment sought to evaluate the influence of varying levels of neutral detergent fiber (NDF) in the diet on feed intake, nutrient digestibility, rumen conditions, and nitrogen retention in crossbred cattle. Beef cattle aged 18 months were organized into groups using a 2x (4x4) Latin square design. The NDF levels investigated were 47%, 51%, 55%, and 59% of dry matter (referred to as NDF47, NDF51, NDF55, and NDF59 treatments, respectively). While dry matter (DM) consumption per 100 kg body weight (BW) did not exhibit significant differences between treatments, Charolais crossbred cattle (2.16 kg DM) demonstrated higher intake than Black Angus crossbred cattle (2.04 kg DM). Metabolizable energy intake in Charolais crossbred cattle significantly differed from that in Black Angus crossbred cattle (17.6 and 16.7 MJ/100 kg BW, respectively). Regarding NDF treatments, NDF47 did not differ from NDF51 and NDF55, but it was significantly higher (P<0.05) than the NDF59 treatment (18.1, 17.3, 17.1, and 16.0 MJ/100 kg BW, respectively). Although dry matter and organic matter digestibility did not significantly differ between Charolais and Black Angus crossbred cattle, variations were noted among treatments (P<0.05). Specifically, DM digestibility of NDF47 (62.8%) was significantly higher than NDF59 (55.4%), with no significant differences observed for NDF51 (59.8%) and NDF55 treatments (58.9%). Rumen pH, N-NH3, and total volatile fatty acid concentrations at 0h and 3h post-feeding did not exhibit significant differences (P>0.05) in this study. However, nitrogen retention in Black Angus crossbred cattle was significantly lower than in Charolais crossbred cattle (0.124 and 0.166 g/kg BW, respectively). Across treatments, nitrogen retention values were numerically higher (P>0.05) in NDF47, NDF51, NDF55, and NDF59 treatments (0.166, 0.148, 0.139, and 0.126 g/kg BW, respectively). In summary, this study determined that Charolais crossbred cattle displayed increased feed intake, crude protein digestibility, and nitrogen retention compared to Black Angus crossbred cattle. Furthermore, a dietary NDF level of 55% was suggested as suitable for practical use in terms of feed utilization by farmers. Keywords: Forage, crossbreeding, rumen fermentation, and ruminant.

MACROECONOMIA DO DESENVOLVIMENTO: UMA PERSPECTIVA KEYNESIANA, JOSÉ LUÍS DA COSTA OREIRO
Authors: Costa da Silva Guilherme Jonas
Published: January 2024

In Brazil, Professor José Luís Oreiro is considered one of the most talented and productive Keynesian economists of his generation. Prof. Oreiro was hired by the Department of Economics at the Federal University of Paraná in 2003, when I came into touch with some of the theories organized in this book.
This book written by Oreiro presents the debate around development macroeconomics from a Keynesian perspective, which is a new and particularly important topic for those who wish to understand a little more about macroeconomics, growth, and economic development.
The main contribution of the book Macroeconomia do Desenvolvimento: Uma Perspectiva Keynesiana is to demonstrate that, for Keynesian theory, macroeconomic policies traditionally more related to business cycles, have effects on long run growth and development. Short run policies affect the long run, because aggregate demand is considered the engine of long-run growth (Keynes, 1982)...
Eddy Currents Assessment of Rail Cracks Using Artificial Neural Networks in a Laboratory Setup
Authors: Gutiérrez Marcelo , Fava Javier , Vorobioff Juan , Checozzi Federico , Ruch Marta , Di fiore Tomás
Published: January 2024

Although flaws associated with rolling contact fatigue (RCF) and the corresponding traffic induced damage, which are a cause of failure in railways, have been of great concern in railway system maintenance and safety strategies in many countries for at least two decades, this serious problem has not been yet adequately tackled in the Argentine railway system. The present upgrading activities undertaken in the Argentine railway system (in infrastructure and in rolling stock) are prompting the need for R&D in non-destructive testing techniques and procedures, to satisfy requirements of the new rolling stock and to ensure safe and economic operation of passengers and cargo. RCF damage appears as surface and near surface defects and grows into cracks which in time will propagate along the running surface and through the cross-section. Eddy current testing (ET) is a very efficient in-service inspection method for this task, the near field technique being especially recommended for ferromagnetic components.

In the present paper, an artificial neural network (ANN) method for automatic classification of flaws with lift-off compensation is presented and tested. The tests consist on the ET evaluation of right angle artificial cracks on a rail calibration coupon; the depth of the cracks studied ranged from 1 to 7 mm. The technique permitted to compensate the weakening of the signals caused by the lift-off effect, allowing signal cracks classification with lift-off variations of up to 5.4 mm.

The effect of crack skewness on the ET signals is also studied. Because the RCF cracks penetrate the rail at oblique angles, (10° to 30° to the rolling surface), an additional uncertainty component is added to the experiments if calibration is made with a piece having perpendicular cracks. In order to estimate this additional uncertainty on the ANN method presented here, further tests were made with a second calibration piece with cracks at 25° to the surface. Comparison of results showed that the peak to peak amplitudes for both types of cracks are not equivalent at all the tested depths.
Comparative Study of PID, PD-FLC and PID-FLC for Active Magnetic Bearing
Authors: Gupta Suraj , Biswas Pabitra Kumar
Published: January 2024

In this manuscript, a closed loop active magnetic bearing system (AMB) is proposed, dynamically modelled and linearized in form of unstable transfer function. To achieve proper bearing operation, the proposed AMB system is controlled by two separate controllers, one to control the current in the electromagnet coils by forming an inner closed loop and second to stabilize the position of the suspending object at equilibrium. To maintain the position of suspending object at equilibrium, for the proposed AMB system (considering inner closed loop as unity) a conventional PID controller, a PD-fuzzy logic controller (PD-FLC) and a PID-fuzzy logic controller (PID-FLC) is designed and their performance is observed and compared. Later, the effect of designed controllers on the complete proposed AMB system is studied with the help of control system plots and improvement among their performances is observed. The plotted step responses and calculated transient state parameters will verify that by changing the conventional PID controller to a PID-FLC could result in 48.34% improvement in overshoot, 41.52% increment in speed of response and 32.23% increment in the relative stability.

Published: January 2024

In this study, date-seed-based carbon was prepared and investigated for the adsorption process on the removal of curcumin dye in an aqueous solution. Carbon is prepared by carbonizing date palm seeds for 3 hours at a temperature of 250°C, followed by a grinding and sieving process. The carbon particles were then characterized using a Digital Microscope, sieve test, and Fourier transforms infrared analysis instrument. The adsorption test was carried out through batch experiments at constant pressure and room temperature. The adsorption results were then evaluated using ten adsorption isotherm models, including Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Fowler-Guggenheim, Hill-Deboer, Jovanovic, Harkin-Jura, Flory-Huggins, and Halsey. Carbon-based adsorbent from date palm seed showed an adsorption capacity in the range of 38.759 mg/g with a suitable adsorption isotherm is Langmuir > Dubinin-Radushkevich > Jovanovic > Freundlich > Halsey. Based on the five best-fitted isotherms, the adsorption process runs normally, spontaneously, and favorably, confirming monolayer and multilayer formation occurs on heterogeneous surfaces. Then, the adsorption follows cooperative adsorption with chemical and physical interactions at one time. The research study presents findings on adsorbents synthesized by date palm seeds for water treatment and their potential applications as adsorbents.

In this study, genetic programming (GP) was the systematic method used to identify the structure and parameters of a mathematical model for ethanol fermentation. The mathematical model simulated the effect of temperature on the kinetics of batch ethanol fermentation and helped to find out the optimum temperature for the better performance of the process. Saccharomyces cerevisiae CSI-1 growing in cane molasses-based media was the microorganism used in all the experiments. Achieving the model’s precision in describing the experimental observations involved the estimation of its structure (non-linear principally) and its constant parameters. The model found describes the fermentation kinetics and showed a fair prediction for Dry cell weight (DCW), Colony forming units/mL (CFU/mL), Residual sucrose (RS), Residual glucose (RG) and Ethanol concentration (E). The model was used to optimize the operating conditions of the process. The predictions from the model in terms of Mean Square Error (MSE) and Sum Squared Error (SSE) fitted the experimental data well with fitness values in a range of R2 ? 0:92.

Published: January 2024

The use of Hardware-In-the-Loop systems implemented in FPGAs is constantly growing due to their performance. However, hardware implementation of numerical methods to solve differential equations presents some challenges when applied to power converters. This paper shows a comparison of several numerical methods: Euler, Heun, Midpoint and 4th order Runge-Kutta, taking into account the accuracy of the methods and how they can be applied to power converters, where the equations change depending on the status of the switches. Results show that the speed in the solution of the numerical method is the main variable that affects the accuracy of the simulation, so in order to keep a fast resolution speed numerical method with low resources should be used.
Controlling the train car´s center of gravity (COG) position based on train load levelling
Authors: Sugiono S. , Nugroho W. S. , Wiryawan E. , Oktavianty O. , Sulistyarini D. H.
Published: January 2024

The dynamic center of gravity (COG) shift of a train car affects the train running stability. Loss of running stability results in derailments and overturns. This study proposes a novel ticketing algorithm as an effort to prevent derailment and overturn. The algorithm limits the freedom for passengers in seat choosing. Instead, the passengers will be offered recommended seat positions that account for a minimum COG shift. The novel ticketing algorithm implementation was tested in comparison to the existing ticketing algorithm and safety-as-priority (SAP) algorithm. Each algorithm implementation was evaluated and compared analytically through a numerical simulation approach. The dynamic COG shift on a few loading scenarios was evaluated using COG loading shift and COG shift. COG shift evaluation shows novel algorithm has smaller shift than existing algorithm but still bigger than SAP algorithm. The loading shift showing the loss of balance during iterative load addition and load reduction has been reduced through SAP and novel algorithm implementation. In the tested loading scenarios, the Existing algorithm shows (x=2.60x10-5,-z=3.41x10-5,y=6.17x10-5)% shift while SAP shows (x=1.28x10-5,-z=-2.40x10-5,y=2.36x10-5)% and novel algorithm shows (x=1.60x10-5,-z=3.07x10-5,y=5.34x10-5)% Cog shift. The result suggests that the novel algorithm has made it possible to maintain train running stability while noticing the passenger needs. Hence, the running safety of a train can be altered without sacrificing passenger satisfaction.

Authors: Kherbouche A. , Benidir A. , Bezzazi B.
Published: January 2024

This paper presents a study about the influence of the size and content of two types of carbon black N220 and N550 with loading of 10–100 phr on the properties of the vulcanized natural rubber (NR).The mechanical characteristics such as the tensile strength, the tensile modulus, the elongation at break, the hardness, the abrasion resistance, and rheological properties of NR reinforced with carbon black were investigated. By analyzing the results of an N220 reinforced NR, the reinforcement gives improvement in tensile strengths when fillers are added up to 70 phr. However, and by referring of elongation at break,  a fall of product elasticity is observed. . The increase of filler loading results a decrease in rheological properties; optimum cure time, scorch time, cure rate index (CRI). Furthermore, the increase of the filler loading leads to the increase in hardness for all the compounds. Compared the reinforcing ability of carbon black N220 scarcely inferior to carbon black N550.However, it seems that the rubber compound filled N220 or N550 gives comparable results on mechanical properties.

Authors: Manoranjani M.
Published: January 2024

Abstract: Wireless Sensor Networks are generally deployed in dynamically changing environment. When compared to common wired network nodes, WSN nodes must do more work. Since WSN devices are battery powered, so power management is a challenge. Clustering is one solution that has been proposed to alleviate the issue of limited power. Clustering is the most important method stabilizes the lifetime of the network. It entails the aggregation of sensor nodes into clusters and cluster head is picked out from all the clusters. Clustering is implemented in wireless sensor networks through the Machine Learning techniques. In wireless sensor networks, machine learning algorithms have an important role in cluster head formation and maintain the stability of the nodes in the cluster. Machine Learning approaches used in wireless sensor networks can be classified as Supervised learning, Unsupervised learning, and Reinforcement learning. Among these learning techniques, unsupervised learning deals with different clustering algorithms such as k-means, K-medoids, Fuzzy C-means, hierarichalbased, and SOM. This paper evaluates the performance of the variants of k-Means (kM) and Fuzzy C-means (FCM) algorithms in terms of the clustering and accuracy. This paper imparts performance analysis of different clustering algorithms in machine learning applied for wireless sensor networks. From the analysis, the Fuzzy C-Means algorithm found to be more suitable for node clustering in WSN

Abstract: The human face is an essential aspect of an individual's body. It plays a crucial function in detecting and identifying emotions since the face is where a person exhibits all of their fundamental emotions. Through human emotions, we solve different types of problems. Like healthcare, security, business, and education. The purpose of this paper is to present the detection of depression in the mental health sector. Depression or stress is faced by most of the population all over the world for many reasons and at different stages of life. As the current human life is a busy life cycle, a person gets depressed or stressed in their daily life. Depression may be found in educational activities, competitive or challenging tasks, employment pressure, family consequences, different sorts of human connection management, health issues, old age, and other situations. Artificial intelligence and deep learning approaches are suggested in this study to assess depression. This research is useful for analyzing the mental health of every employer and psychologist when counselling their patients. Here, we propose a deep convolutional neural network (DCNN) model. This model can classify two types of human facial emotions. Which is based on positive and negative emotions. This model is trained and tested using the FER-2013 dataset. The data set used for experimentation is a FER (Facial Expression Recognition) dataset available in the KAGGLE repository. The implementation environment includes Keras, TensorFlow, and OpenCV Python packages. The result includes the emotion detection accuracy between the training and test phases. The average accuracy achieved was 77%.
Analysis of Long Span Steel Tied Arch Bridges
Authors: Rane Prabhanjan R.
Published: January 2024

Abstract: Arch bridges construction has reappeared around the world thanks to the cantilever launching method, and nowadays these structures represent one of the three major types of long-span bridges, with the other two types being suspension and cablestayed bridges. The arch rib is an element mainly subjected to a large axial compression force caused by dead loads, and that’s why arch bridge structures exhibit a complex behavior during strong earthquakes. Furthermore, when a bridge is located close to a fault system, the near field effects must be considered, since the structure could experiment with large displacements. This research work aims the analysis and structural stability of a Network arch bridge – a tied-arch bridge with inclined hangers that cross each other at least twice. A comparative analysis with other type of hanger arrangements i.e. a tied-arch bridge with vertical hangers is performed. Possible analysis solutions with respect to spans, materials and carriageway width are presented and succinctly discussed. Earlier this kind of analysis was not possible due to limited processing power, but with better software and available processing power, it is possible to estimate the response of structure more accurately. Modelling using a tri dimensional finite element model of the arch bridges are described through MIDAS CIVIL Software in this research work. Two arch bridges are modelled with different arrangements of hangers – a vertical and inclined network type arrangements – under same load parameters. Comparative analysis is carried and studied in terms of fluctuations in member forces, bending moments, deflections, and behavior under seismic excitation.

In mushroom cultivation, it is important to be aware of the impact of the growing substrate. This study investigated the cultivation of various oyster mushrooms, including Pleurotus ostreatus, Pleurotus citrinopileatus, and Pleurotus djamor, on different types of wood sawdust. Total phenolic content, condensed tannins, antioxidant activity by ferric reducing antioxidant power assay, protein and sensory evaluations were performed in cultivated oyster mushrooms. Wood sawdust of Fagus orientalis (oriental beech), Alnus glutinosa (alder), Castanea sativa (chestnut), and Juglans regia (walnut) were used as substrate for studied mushroom type, separately. Because champignon (Agaricus bisporus) was the most consumed mushroom, it was used as control sample. Methanolic extracts of dried mushrooms were used to measure bioactive characteristics. Pleurotus ostreatus samples cultivated in Alnus glutinosa (alder) sawdust substrate had the highest antioxidant activity. The lowest antioxidant activity values were found in Pleurotus djamor cultivated in Juglans regia (walnut) wood sawdust substrate. The highest protein content was measured in Agaricus bisporus as 13,84 %. The other highest protein concentration was found in Pleurotus ostreatus cultivated in Alnus glutinosa (alder) sawdust substrate, at 13,75 %. The lowest protein concentration belonged to Pleurotus citrinopileatus cultivated in Fagus orientalis (oriental beech) sawdust substrate as 9,86 %. While Agaricus bisporus and Pleurotus ostreatus had the highest overall appreciation score, Pleurotus citrinopileatus had the lowest. It has been observed that the substrate content has an important impact on chemical and sensory properties of the oyster mushrooms.  This study provides knowledge on the chemical and sensory characteristics of three different Pleurotus mushroom species cultivated on different composts.

Авторы в данной статье затронули вопрос об интервокальной согласной буквы འ ’a, именуемая в тибетской грамматике как, а chung. Данная проблема затрагивался учёными монголоведами и ранее, однако до настоящего времени остаётся все же открытым и до конца не разрешенным. Интервокальная γ/g старомонгольского письма в квадратном письме Пагба-ламы замещается тибетским полугл–асным འ ’a, которая не читается. Тибетское письмо на базе, которого была создана квадратное письмо является абугидой, где гласные буквы выражаются не самостоятельными буквами как в старомонгольском письме или же вообще при фонетическом письме, а специальными диакритическими знаками. Поэтому графически в квадратном письме неуместно писать вслед за какой-либо гласной буквы другую гласную. Иными словами диакритический значок, выражающий какую-либо гласную букву в квадратном письме, обязательно присоединяется к определённой базовой согласной. Эту функцию и выполняет полугласный འ ’a, которая в тибетской грамматике считается нулевой морфемой, т.е., которая не читается или же не произносится, но пишется при письме.

Oral tales, which are known as “tales of the fiddle” (quγur-un üliger or bengаsün-ü üliger) derived in the eastern part of Inner Mongolia, are well-inherited to this day and have been the focus of many Mongolist scholars since long ago. Although many international scholars studied the tales of the fiddle from different perspectives, there is a lack of study on lexicological components in the tales of the fiddle. In this paper, author chose the “Romance of the Three Kingdoms (in Mongolian: γurban ulus-un üliger; in Chinese:三国演义)” which was performed by Bürenbayar bard (quγurči, Lit: the fiddle player) as a research object. It was broadcasted by the Khulun Buir Radio Committee for a total of 62 hours length in August 1984. The author considered these materials as oral sources (transcriptions of audio recordings) for his research and conducted a comparative lexical analysis between the original Chinese text and other Mongolian translations. The Chinese source of the “Romance of the Three Kingdoms” contains 209 stanzas (192 poems, 2 hymns, 2 panegyrics, 2 eulogies, 10 songs, 1 children's tale), 3 of which correspond to the selected tale of the fiddle. In addition, the vocabulary items of the bards and some words of the local dialect were compared with the words used in two other translated versions of the "Romance of the Three Kingdoms", which were translated by Temget and D. Boldbaatar translated from Chinese into Mongolian. In this article, the author not only summarizes the study of the “Romance of the Three Kingdoms” and its translation into Mongolian, but also compares Burenbayar's tale of the Fiddle with other Mongolian translations of the “Romance of the Three Kingdoms” in terms of lexical components and features of poetry, and it was determined that the tale of the fiddle originated from Temget's translation of the Romance of Three Kingdoms.

The article analyzes the poems and some stories and plays of S. Buyannemekh, the modern Mongolian writer, identifies the experience of using symbols in his writings, and deciphers the main symbols. Analyzing the symbolic experience in S.Buyannemekh's writings, 1. S.Buyannemeh uses the Mongolian mythological tradition of symbolizing divine ideas with natural phenomena such as sunlight, moonlight, rain, rainbow, wind, and eastern mythological or Buddhist symbols such as gardi galbinga, Bodhi tree, and Land of Sugaavid, and further in his writings, used creatively. 2. S.Buyannemeh uses Chinese culture items such as snuff, cane, long pipe, Chinese fan, and religious superstition items such as “Puffball of Heaven” and “barley dolls” in his writings as ironical symbols of the disappearing culture. To this end, he created new symbols in Mongolian literature by depicting new cultural items such as bread, books, buildings, roads, helicopters, telephones, and mirrors in his short stores and plays while promoting new culture and ideology to the masses.

The cumulative effect of economic news in the media: patterns of faith and disappointment
Authors: Konoplev Dmitry E.
Published: January 2024

On the example of three thematic layers, the specifics of the presentation of economic ideas in media publications and the transformation of the approach to these ideas over time are considered. The author refers to the ideas of modernization, import substitution and business support during the coronavirus pandemic and sanctions restrictions, arguing that the information context of these information layers can be described through patterns of faith and disappointment. By the methods of content analysis and sentiment analysis it is fixed that there is a final and cyclical scenario for the coverage of economic ideas in periodicals. In the first case, the cumulative information effect ends with the media's disappointment in the broadcasted idea and its exclusion from the news agenda. The author notes that the cumulative resonances responsible for the transmission of economic ideas accumulate a negative context, although initially they may be oriented towards the presentation of positive news. Their exhaustibility in the media can be associated with the obsolescence of the newsbreak that gave rise to them, and with the formation of a pattern of disappointment in the relevant texts. It is concluded that the cumulative resonances in the media, exploiting the pattern of faith, can form explanatory models in journalistic texts, which are based on economic stereotypes.
Biopolitical media discourse in France in the COVID-19 pandemics
Authors: Bannikov Konstantin V. , Radina Nadezhda K.
Published: January 2024

The publication activities of the French media during the COVID-19 pandemic in a biopolitical way are analyzed. The theoretical frame of the study is set by Michel Foucault's concept of biopolitics, as well as the propaganda model of Edward Herman and Noam Chomsky. To collect and analyze empirical data, the methods of computational linguistics and the method of identifying contextual ideologemes were applied. The research materials were the texts of independent media (Le Figaro, Le Monde, Le Parisien), identified using the keywords “pandemic” and “COVID-19” during the four waves of the pandemic (from January 2020 to March 2022). A total of 29,584 Le Figaro articles, 22,446 Le Monde articles, and 6,402 Le Parisien articles were used in the research. The purpose of the research is to analyze the strategies for including the French media in the biopolitical practices of propaganda and public education on the example of the COVID-19 pandemic. As a result of the research, it turned out that the studied media during the pandemic were integrated both into general information campaigns and into biopolitical education and propaganda campaigns. Two scenarios for organizing media discourse during the pandemic of COVID-19 were identified, determined by target groups and media tasks. The first scenario actively involves educational and propaganda tools to promote state biopolitical goals. The second scenario integrates informing readers about the COVID-19 pandemic and the measures used by the authorities for biopolitical control, with the presentation of the hierarchies of responsible persons/ institutions (within the state biopolitics). It is concluded that the participation of French independent media in the active promotion of biopolitical programs indicates their close connection with the actors and subjects of biopolitics - the state or business representatives.

Strategies for Сreating the Image of a Politician in an Arabic Polycode Text of the Series “٣ اختيار”
Authors: Dugalich Natalia M. , Shavtikova Aurika T. , Izildin Okil
Published: January 2024

According to the classification of speech strategies by O.S. Issers, semantic, lexicogrammatical, and pragmatic indicators act as linguistic indicators of speech strategies. The article is devoted to the analysis of the most significant linguistic and extralinguistic aspects of speech strategies that are used to create the image of the President of Egypt Abdel Fattah Khalil El-Sisi in the movie series “٣ اختيار ” (The Choice 3). These strategies were considered as part of the analysis of the Arabic polycode text, which is presented as the integrity of verbal and non-verbal components. The material of the study was the communicative acts of the main characters and the video sequence of the analyzed series, in which the authors recreated the revolutionary era of Egypt in 2013. The novelty of the study is an attempt to characterize Arabic political discourse as an independent linguistic phenomenon. As a result of the study, the authors arrive at the conclusion that the creation of the image of a politician requires such semantic indicators of speech strategy as: submission, threat, discrediting; lexico-grammatical indicators: syntactic synonyms of various types, paremiae, dialectal forms. The effect of applying these communication strategies, which create the image of the Egyptian president, is enhanced by extralinguistic parameters and symbols studied within the theory of the polycode text. The analysis of the interaction of codes of various genres of the polycode text in the Arabic political discourse is of interest for further research.
