Authors: Yahya Aaisha Mohand , AL-Zakar Shatha H.D. , AL-Mohseen Kamel A. 
Published: April 2024

Since Makhol dam is planned to be constructed on Tigris River to the north of Baiji discharge measurement station, it is essential to study the nature of inflow into this reservoir. The information concerning this inflow is of great help in operating and management of the prospective reservoir. From our point of view, it is necessary to know how these inflows are distributed and contributed to Tigris from different upstream sources. Disaggregation flow models are stochastic generation techniques, that used to divided data into lower time scales from higher time scales using parametric approaches with two main categories: spatial and temporal. In the streamflow disaggregation model, historical data statistics (mean, skewness, standard deviation, maximum, and minimum) can be preserved while distributing single-site values to several sites in space and time. In this study, the aggregated streamflows data at a key station will be disaggregated into a corresponding series of discharges at sub-stations that are statistically similar to those observed by applying Stochastic Analysis Modeling and Simulation (SAMS 2010) software. To investigate the appropriate the disaggregation method for modeling monthly flow data, we used the annual and monthly data flow of five gauging stations in the Tigres River in Iraq (Mosul Dam station on Tigris river, Asmawah on AlKhazir river, Eski Kalak on Upper Zab, Dibs Dam on Lower Zab, and Baiji station on Tigris river) for the duration 2000–2020. The application approach's statistical outcomes were contrasted with their historical counterparts and the results showed that most years and months at all stations were in good agreement with the historical data. Therefore, we argue that this method have ability to be used when making decisions about water management strategies in these regions which is essential for water resource managers and decision makers.

Authors: Sadekov Rustem Rafekovich 
Published: April 2024

In the work, the author examines problematic issues related to the study of the peculiarities of the organization and legal regulation of the use of a polygraph in public service. The article deals with various aspects of the use of a polygraph in the public sphere, including legal aspects, psychological and pedagogical features, physiological and ethical issues, as well as the protection of citizens' rights. In addition, it examines the experience of using a polygraph in various conditions when the procedure for obtaining, identifying, processing, storing and reliability of data is carried out, and as a result, it becomes necessary for competent public sector specialists to constantly pay special attention to the safety of storing and using confidential information received. In order to analyze the effectiveness of the use of a polygraph, the paper describes the tasks facing specialists, considers algorithms and techniques used to assess the reliability of the information received. The following methods were used in the preparation of the article : an analysis of literature, a system approach, comparative analysis and synthesis, induction and deduction, logical thinking techniques, classification. The main conclusions of the research conducted by the author are organizational aspects aimed at respecting the rights and freedoms of citizens who, for one reason or another, will have to undergo the testing procedure on a polygraph device. A prerequisite is the fact that the legal regulation of the use of a polygraph in the civil service requires clear formulation, transparency and objectivity of procedures, timely clarification of the upcoming nuances of the polygraph examination, related possible restrictions, but at the same time compliance with guarantees for employees who are being tested. This topic, in its content and meaning, is relevant, and therefore, today, the development of legal and methodological mechanisms for the use of a polygraph in the public sphere, based on scientific developments by leading scientists and practitioners in this field of knowledge, is in demand.
Images of Scythian-Siberian Animal Style in Siberian Neoarchaics
Authors: Zenina Tatyana V. 
Published: April 2024

The article considers Siberian neoarchaic as a trend of modern art, which originated in the early twentieth century. The aim of the study is to trace the stages of formation of Siberian neoarchaic as a style from the emergence to the present day, to identify the artists who worked within the framework of this trend and the Scythian-Siberian animal style. Important research tasks are to answer the question about the reasons for the appearance of Scythian art motifs in the works of contemporary artists and to analyze the ways of artistic borrowings in different types of art. The relevance of the work lies in the fact that modern society (and art) is in the process of searching for self-identity, and the appeal to ancient traditions and cultures is one of the most accessible tools on this path.On the basis of the comparative method and visual analysis of works, the author has identified artists who are bright representatives of Siberian neoarchaics, and from the 1960s to the present time have made a significant contribution to the history of art, using images of the Scythian animal style in their works. The analysis was preceded by a stage of studying the autobiographies of the painters and interviewing some living masters, which allows us to draw a conclusion about the reasons for their turning to such a narrow theme within the broad direction of Siberian neoarchaic art, as well as to identify the factors determining the formation of the author’s style. The works of 10 artists are analyzed in chronological order, unambiguous visual parallels with specific monuments of Scythian art are made, methods of artistic borrowing and techniques are outlined. A review has been carried out, which can be considered the first step towards the practical formation of the list of masters actually creating this trend. The stylistic features of Siberian neoarchaic art are revealed, which form the prerequisites for the formation of a methodological basis for the study of works of this style, a promising direction of art history research.

Authors: Khisamov Denis N. 
Published: April 2024

Vyacheslav Vladimirovich Samodurov is one of the brightest choreographer-directors in contemporary Russian ballet. Despite the fact that at present V.V. Samodurov is a free artist who has entered a new stage of his creative biography an important milestone on the way of the master is his staging activity, carried out in 2011—2023, the period of his work at the Yekaterinburg State Academic Opera and Ballet Theatre (“Ural Opera Ballet”). The productions of the Yekaterinburg period allow us to draw a conclusion about the features of V.V. Samodurov’s style, which determine the creative image of the master. At the same time his creative heritage of the period of his work with the “Ural Opera Ballet” company has not been subjected to a comprehensive art history analysis. This fact reveals the relevance of the topic of the article.The aim of the research is to identify the features of V.V. Samodurov’s production style, manifested during his activity as a choreographer of the “Ural Opera Ballet” company. The novelty of the article lies in the fact that for the first time in the research of scientific character the features of V.V. Samodurov’s staging style are generalized and systematized. On the basis of the comparative analysis of his productions performed during the Yekaterinburg period of the master’s creative biography, generalizations were made, which testify to the combination of traditional and individual innovative features in the master’s staging style, defining the creative image of the choreographer.

Published: April 2024

Purpose: This study examined the impact of working capital management on the financial performance of alternative energy in the UK from 2015 to 2022. The proxy used includes receivable turnover, payable turnover, inventory turnover and return on asset. The study employs an ex-post facto research design using panel data from the sampled firms' annual reports.

Methodology: The panel data were analysed using descriptive statistics, correlation matrix and panel regression analysis. The Hausman specification test showed that the fixed effect was more appropriate.

Findings and Conclusion: The findings show that receivable turnover has a significant positive impact on the return on assets of the alternative firm in the UK. In addition, payable turnover has a significant negative effect on return on assets, while the findings on inventory turnover have an insignificant impact on return on assets. These findings imply that working capital management significantly affects the financial performance of alternative energy firms in the UK. Based on the conclusion, the study recommends that oil and gas firms increase their net cash flow from operating activities to increase their financial performance.

Originality/Value: Globally, it is acknowledged that many companies fail due to poor working capital management. This study contributes to knowledge by examining the effect of working capital management on the financial performance of alternative energy firms in line with sustainable development goals in achieving a sustainable UK economy. This has not been previously studied.

Authors: Pinto Karen Esteves Fernandes , Oliveira Junior Moacir Miranda , Fernandes Carolina Cristina 
Published: April 2024

Objective: The purpose of this study is to analyze the relationship between Sustainability-Oriented Innovation (SOI) and Corporate Social Responsibility (CSR) in Brazilian multinationals.

Theoretical Framework: The theoretical framework provides relevant information on CSR and SOI, which forms the basis for the development of hypotheses.

Method: To collect data, an e-survey was conducted with Brazilian multinationals operating in various industries and segments, resulting in 60 valid questionnaires. The data was analyzed through multivariate analysis, employing canonical correlation and multiple linear regression procedures.

Results and Discussion: The results of the multivariate analysis empirically supported five hypotheses (h1, h2, h3, h4, and h5). However, the results did not support the hypothesis that predicted a positive correlation between SOI practices and CSR as a differentiation strategy.

Research Implications: The practical and theoretical implications of this research are significant, particularly in shedding light on emerging market multinationals, with a specific focus on Brazilian companies. By specifically examining Brazilian multinationals, this research fills a crucial gap in the literature, offering insights into the unique challenges and opportunities faced by firms from an emerging market like Brazil.

Originality/Value: The findings of this study provide valuable guidance for Brazilian multinational corporations seeking to enhance their CSR initiatives and SOI practices. By understanding the relationships between CSR, SOI, and other key variables, these companies can develop more effective strategies to navigate global markets while simultaneously addressing social and environmental concerns.

Authors: Soraya Arditya 
Published: April 2024

The objective of investors to invest their money was to maximize return, although they were subject to constraints, primarily risk, so this study aims to provide an alternative to the formation of portfolios and corporate bonds to obtain optimal returns with acceptable risk. The alternative model is to combine Graham's stock selection model with the formation of an optimal portfolio model, namely the Markowitz model. The results of the selection using the Graham model of defensive investors and aggressive investors are 9 and 13 stocks, respectively, of the 45 stocks listed on the LQ45 index. From the selected stocks, the optimal portfolio is formed using the Markowitz model. The results show that the Markowitz model optimizing portfolio provides better performance (reward to variability ratio) than the LQ45 portfolio index with a yield difference of 13.68 – 20.24% per year. Furthermore, the selection of corporate bonds for the optimal portfolio resulted in 8 corporate bonds with a portion of each bond, and this portfolio can generate rates of 8.88% per annum.JEL: G10, G11, G12

Published: April 2024

This study investigates the effect of stock selection, market timing, and fund size on the mutual fund’s performance with Covid-19 as a moderating variable. The sample data is limited to the listed conventional mutual funds supervised by the financial service authorization from 2014 to 2021, denominated in Rupiah currency, have a complete report, and have more than Rp 350 billion in fund equities. The sample data implements twenty-eight of the listed conventional mutual funds and is examined by a random method of Panel data multi-regression with moderated regression analysis (MRA). The result shows that market timing positively affects, and Covid-19 can enhance the effect of stock selection on the mutual fund’s performance. Meanwhile, stock selection, fund size, and Covid-19 do not affect the mutual fund’s performance. Covid-19 cannot moderate the effect of market timing and fund size on the mutual fund’s performance. Fund managers highlight market timing as a crucial indicator of obtaining more returns, and Covid-19 is the best moment to select and collect potential stock at affordable prices and trade them to get more returns after the crisis.

Authors: Sukri Ridwan Ahmad , Effendhy Syafiq 
Published: April 2024

<p class="Abstract">What is meant by national resilience? National resilience is
a dynamic condition of all aspects of national life that contains tenacity,
strength, and toughness with the ability to develop national strength to face
and overcome all threats, challenges, obstacles, and disturbances, both coming
from within and outside the country, directly or indirectly. Endangering the
integrity, identity, and survival of the nation, and the struggle to achieve
national goals. National resilience is a fundamental need that must be pursued
so that a nation continues to exist. Indonesia's national security has
experienced disruption in the form of the Covid-19 pandemic. Bondowoso Regency
responded in various ways to face and anticipate possible obstacles in the
future. Of course, these efforts cannot be separated from the roles of leaders.
Leaders play an important role in mobilizing and optimizing the resilience
potential that exists in society. In Bondowoso, where the majority of the
population is Madurese, there are at least two types of leaders: formal and
informal. Formal and informal leaders in Bondowoso Regency actually have good
relations with each other, synergize, and collaborate. Like Madurese society in
general, the Bondowoso people have local wisdom in the form of a hierarchy of
leaders that must be obeyed, and formal leaders such as the government are in
fourth place. This article focuses on an ethical review of the relationship
between formal and informal leaders in building strong community resilience. The
model of good relations between leaders in society can be a model for building
national resilience that can be imitated by other ethnic groups in Indonesia,
because in various ethnic groups in Indonesia, there are two types of leaders:
formal and informal.<o:p></o:p></p>
THERMODYNAMIC ANALYSIS OF REDOX REACTIONS OCCURRING DURING GALVANOCOAGULATION WASTEWATER TREATMENT
Authors: Kurilina T. , Pazenko T , Kurilin S. 
Published: April 2024

Abstract. One of the most important environmental problems is the purification of industrial wastewater from heavy metal ions. Various methods are used to solve this problem: chemical, physico-chemical, sorption, but the most promising method for cleaning industrial wastewater containing heavy metal ions, namely copper, nickel and zinc, is the galvanocoagulation method. However, the literature does not sufficiently cover the processes of cementation of heavy metals on cathode loading. A physico-chemical approach to this process is necessary to confirm the process of separation of heavy metal ions from wastewater in the form of sediment and the creation of new industrial wastewater treatment schemes. The composition of the loading is essential in galvanocoagulation neutralization, therefore, in order to determine the effect of the type of active loading, a carbon mineral sorbent (SGN) obtained from ores of cryptocrystalline graphite (Noginsky deposit of the Krasnoyarsk Territory) was used. The studies were carried out in a galvanocoagulation module by passing wastewater through a loading consisting of a mixture of iron shavings and granules of carbon mineral sorbent based on ores of cryptocrystalline graphite (SGN). At the same time, the air dispersed in the lower part of the device was bubbled through the loading. As a result of the operation of the Fe-SGN short-circuited galvanic cell, iron scrap was dissolved and its intensive oxidation to Fe3+ by air oxygen. The article considers the mechanism of galvanocoagulation neutralization of wastewater based on thermodynamic analysis of redox reactions occurring during galvanocoagulation wastewater treatment.
Subject of the study: both model and real wastewater from the production of electroplating coatings containing copper, zinc and nickel ions with the following concentrations were used: =60 mg/dm3; =15 mg/dm3; =20 mg/dm3
Materials and methods: galvanocoagulation neutralization using a short-circuited Fe-SGN galvanic cell (carbon mineral sorbent)
Results: the physico-chemical patterns of the galvanocoagulation process of wastewater treatment have been studied and the thermodynamic parameters of heavy metal ion reduction reactions have been determined
Conclusions. It has been experimentally established that it is possible to intensify the process of galvanocoagulation of wastewater containing heavy metal ions by using a carbon mineral sorbent as a cathode loading, which reduces the processing time with a high purification effect and a difficult-to-dissolve precipitate is formed.

Un asegurador en salud preocupado por el alto costo de los exámenes de laboratorio solicitados a los pacientes y los medicamentos formulados, decide tomar la decisión que crear estímulos económicos para los médicos que menor número de exámenes soliciten a los pacientes y los que se destaquen por el menor valor total de los medicamentos formulados en cada trimestre del año.
El Gerente de la aseguradora y el Director de un Hospital donde atienden muchos de sus pacientes, se reúnen con todos los médicos vinculados laboralmente a la institución prestadora y después de plantearles la preocupación por el costo creciente de la atención de salud de los pacientes y su impacto en la sostenibilidad futura de la aseguradora e indirectamente del sistema de salud, les comunica la decisión que han tomado de incentivar la utilización racional de exámenes de laboratorio y medicamentos. Les explica que trimestralmente se publicará el ranquin de los médicos de acuerdo con estos dos ítems y a los que queden en los primeros lugares de menor utilización les darán un estímulo económico.
Los médicos en general están de acuerdo con la decisión con excepción de un pequeño grupo que se opone por considerar que esta decisión afectará negativamente la calidad de atención médica e implicará una violación de la ética que debe regir la relación médico – paciente – institución de salud. Al no tener eco su reclamo a la institución y aseguradora, ni apoyo de muchos de sus colegas, deciden consultar a un Comité de Ética Médica al respecto.
