This research is carried out to examine the financial structure in terms of liquidity analysis of Ambuja Cement. Objective: To evaluate financial performance analysis of Ambuja cement for liquidity analysis. It assumed that there is no significant difference in liquidity ratio of Ambuja cement for financial year 2013 to 2022. Time Taken for Study: Normally it is not possible for the researcher to study the financial performance of any cement company for longer period because there is constrain of the time, money and efforts. So, the present study is done for ten years of period because of convenience for proper data collection and analysis for the period of ten years for the study. The present study is made for a period of last ten years i.e. accounting years 2013 to 2022. Parameters of the Study: Liquidity Ratios. Tools Used for Study: Descriptive Statistics and Analysis of Variance (ANOVA) Findings of the Study: The firm has failed to balance the current ratio for financial year 2021 only. Similarly, the quick ratio values can be good for firm if it has measured one or more than one. The ideal quick ratio is not found good for the financial year 2017, 2021 and 2022. It shows that the firm is failed to balance liquidity during the said years. It is observed that for each financial year the firm has least value of inventory turnover ratio of 8.89 for financial year 2019 and highest is measured for the year 2022. It is indicating that the firm has balanced inventory for each year.  The ideal dividend pay-out ratio on net and current price is tends to the financial circumstances of the firm. It is observed that the firm has paid least dividend during   financial year 2019 and 2020. It may be due to the Covid-19 pandemic.

Making Relationships Count: Measuring Trust in Relationships Between a Catholic Development Agency and Māori Communities
Authors: Leuthart Gretchen , Prinsen Gerard
Published: January 2023

Abstract: Relationships affect outcomes in the international development sector, yet there are few frameworks or indicators to measure trust as a foundation of relationships. This article describes an emergent framework for evaluating trust in cross-cultural relationships. It is based on a case study of Caritas Aotearoa New Zealand and its Indigenous partners. Perspectives on monitoring and evaluation (M&E) and measuring trust are explored from an Indigenous world view. Interviews with five people representing all parties suggest various types of behaviours that indicate trust. Through this exploration, culturally competent M&E and the centrality of relationships in expanding evaluation practice are revealed.

Fostering an Evaluative Culture by Addressing a Breakdown in the Policy Development Cycle
Authors: Anderson-Draper Michelle
Published: January 2023

Abstract: Systematic evaluation contributes to a strong governance function that leads to improvement and accountability in school systems. Evaluation is integral to the policy development cycle. Elected school board trustees in River City school division were challenged in their governance role by a lack of evaluative feedback on policies. A four-step change process was created to guide the development of an evaluation framework to address the gap and foster an evaluative culture within the board. The change process described could be applied by other school divisions to enhance their policy evaluation function. More broadly, the importance of careful planning and the benefits of a participatory approach to evaluation are integral pieces to any change effort.
Education strategies for sustainable development in modern Russian society
Authors: Iao Liubov Markelovna
Published: January 2023

Among the main directions of Russia's transition to sustainable development is the formation of an effective system for promoting the ideas of sustainable development and the creation of an appropriate system of upbringing and education. At the heart of any civilization is education – the transfer to subsequent generations of acquired experience and knowledge, cultural and moral values. To overcome the global ecological crisis in which mankind found itself at the beginning of the 21st century, it is necessary to develop the principles of the relationship between man and nature. In this regard, education for sustainable development is of great importance. To study this problem, sociological methods were used – quantitative surveys, analysis of normative documentation, meaningful analysis of plans and reports of authorities. The results of the study showed the presence of two trends in education for sustainable development, the basis of which is environmental education at all levels of the education system in Russian society: one trend is the curtailment at the federal level, the second is attention to environmental education in certain regions of the country, especially where environmental the situation is the most difficult.

Remittances are the funds sent by individuals to their home country from the host country and are the main source of foreign funding after FDI. Remittances are a crucial source of subsistence for the countries that are still in developing phase. Due to of the increasing scale and effect on the origin country, the international remittance flows into the developing country have gained the attention of numerous analysts from all over the world. This study examines the role of foreign remittances in poverty alleviation utilizing the panel data set of Asian countries, precisely nine developing countries. For the dependent variable this study uses poverty gap and the independent variables are Remittances as percentage of GDP, Per capita GDP, External debt as percentage of GNI and Trade openness as percentage of GDP. The findings reveal that foreign emittances have a significant role in alleviating poverty gap.  The results of the random effect model showed that a 1% increase in international remittances as percentage of GDP leads to a decrease of 65.932% in poverty gap at $1.90 poverty line in the sample developing economies from 1990-2019. In addition, the results indicate, trade openness and per capita GDP decrease poverty and external debt seems to increase poverty.

2D material research, which has been actively researched recently, has had an impact on 1D material research and development through the concept of related material expansion. Although 1D nanowire materials are expected to fuel advances in electronic applications, there is still much to be explored in terms of material diversity. We would like to introduce a variety of quasi-1D materials based on vdW (van der Waals) bonding having a chemical composition of M2N3Se8 (M2N3S8), which is being studied recently. We would like to explain the polymorphism structure and device application characteristics that can occur during the synthesis materials, and the possibility of band-gap engineering through alloying of M and N transition metals and Se-S substitution. Through this, we intend to propose various possibilities of application of the quasi 1D M2N3Se8 (M2N3S8)material system proposed in this paper.
Electrochemically Exfoliated Two-Dimensional Nanomaterials for Electronics
Authors: Kang Joohoon
Published: January 2023

Two-dimensional (2D) nanomaterials have been considered as a promising materials platform for next-generation electronics due to their unique electronic, optical, and mechanical properties. Since the first graphene exfoliation method has been reported, other layered materials having the structural analogues with different electrical properties have been further explored to discover semiconducting candidates. For example, semiconducting MoS2 has been widely studied for electronic device applications including transistors, phototransistors, diodes, and logic gates. However, the technological limitations to produce wafer-scale MoS2 thin-films only enable to demonstrate prototype electronic applications. To overcome this limitation of scalability, solution-based processing has been considered as a strong candidate. In particular, molecular intercalation driven electrochemical exfoliation method can produce high quality 2D nanosheets in large quantity without vacuum- or high temperature-related processes. In this article, solution-processed 2D materials will be introduced as a potential platform toward wafer-scale, high-performance electronics and future outlook will be provided as important aspects should be considered to apply this materials platform for the real-world applications.

Published: January 2023

Collecting, which is a niche area of consumer behavior, has been given little research attention by marketing scholars. Based on an extensive literature review and primary data collection through in-depth interviews, conducted in Turkey, the present study intends to understand collectors’ motivations and emotional outputs of the process. Additionally, it also aims at classifying collector typologies based on their starting point of collecting and revealing the differentiated motives and emotional outcomes of each typology. The findings indicate that all of the participants in all groups stated that they are addicted to collecting. Within groups, Family collectors differentiate with passion for research and childhood collectors with nostalgia whereas leaving a heritage to the future and self-expression are the main motives of adulthood collectors. On the output side, the pleasure/satisfaction derived from collecting has been the common point of all collector groups. Besides, the percentage of pleasure takers in the A.C. is slightly lower than in other groups. Other positive outputs of collectors are listed as socializing, differentiation, and self-confidence. This typology will bring in more clarity and further insights that will help scholars; expand the research domain and it helps sellers of collectibles.

Authors: Hutsul Khrystyna , Kiyko Yurii
Published: January 2023

The article is devoted to the establishment of listening strategies of senior students of a Ukrainian general secondary education institution who study German as a second foreign language. On the basis of student questionnaires, listening strategies of German as a second foreign language learners were identified.
The study shows that mastering listening strategies contributes to the successful understanding of the audio message and the improvement of results during the performance of tasks for the development of this competence. The survey of the participants made it possible to identify the most frequent listening strategies used by high school students at three stages of the listening task: preparatory, while listening to the audio recording, and after completing the task. It was established that the most frequent listening strategies among high school students are strategies related to the functioning of memory mechanisms, as well as predictive strategies. In the process of perceiving and understanding speech by ear, high school students use the "top-down" approach, guessing the meaning of unfamiliar words based on the context and filling in information gaps based on familiar words and phrases. By performing the corresponding task, students regularly use strategies for predicting possible answer options in the presence of visual support for the printed text, recognizing grammatical constructions, predicting the content of the audio text, and their background knowledge.
РОЗПОДІЛЕНА САМООРГАНІЗОВАНА СИСТЕМА ПРОГНОЗУВАННЯ ЗЛОВМИСНОЇ АКТИВНОСТІ В КОМП’ЮТЕРНИХ МЕРЕЖАХ
Authors: Каштальян Антоніна , Любінецький Денис
Published: January 2023

У роботі розроблено самоорганізовану систему прогнозування зловмисної активності в комп’ютерній мережі згідно алгоритмів роботи глибокого навчання. Крім того, було представлено нову самоорганізовану інкрементну нейронну мережу під назвою FG-SOINN написану мовою програмування Python. У SOINN видалення вузлів і ребер визначається двома параметрами, які потрібно оптимізувати для кожної наявної програми за допомогою перехресної перевірки або подібних підходів повторної вибірки. FG-SOINN усуває цей недолік, розглядаючи видалення вузлів і ребер як невід’ємну частину процесу навчання. Було сформульовано три концепції для формування «сміттєвого забуття»: час простою, надійність і корисність завдяки чому мережа видаляє вузли та ребра. Така мережа базується на концепті «навчання без вчителя» і може працювати із штучними та реальними даними і, навіть, за раптових або повторюваних відхилень.
Namibian Poetry as an Expression of Agony: A Postcolonial Analysis of Thaniseb’s Searching for the Rain, Kahengua’s Dreams and Iizyenda and Kinahan’s (ed.) My Heart in your Hands
Authors: Tomas Lahja , Mlambo Nelson
Published: January 2023

This paper analysed how different Namibian poets have utilised different poetic devices to depict the theme of agony in Namibian post-independence poetry. Guided by the postcolonial theory, the paper looked at the use of different poetic devices in selected poems from three Namibian anthologies, Dreams, My Heart in your Hands and Searching for the Rain. The study found that certain socio-political and socio-economic issues act as the main catalysts for the agony prevailing in post-independent Namibia. Such issues include poverty, unemployment, inequality and disillusionment. These issues are the most prevailing themes in the selected poems. In the same vein, the study found that these postcolonial issues play a significant role in the struggles of the masses in post-independence Namibia. Furthermore, the study established that most poets have employed similar poetic devices to portray different dimensions of suffering experienced in the postcolonial era. The commonly used devices are onomatopoeia, imagery, irony, repetition, simile as well as personification. Lastly, the study established that Namibian poets have successfully employed different poetic devices to highlight and emphasise the struggles faced by Namibians in the post-independence era.
Assessment of the possibility of using the measurement of open time to assess and verify the constancy of performance of cementitious ceramic tile adhesives
Authors: Stancu Cristina , Dębski Dawid , Michalak Jacek
Published: January 2023

The study analyzed the results of open time measurements of ceramic tile adhesives after not less than 30 minutes, obtained by 27 laboratories participating in the interlaboratory comparison program. The obtained results were statistically analyzed following the requirements of ISO 13528 and assessed under the z-score analysis criteria contained in the EN ISO/IEC 17043. 22 out of 24 laboratories that sent the results of the open time measurement confirmed their competencies, obtaining a “satisfactory” result following the evaluation criteria. The result obtained by one laboratory was classified as “questionable”, and another received the result as “unsatisfactory”. From the perspective of laboratories participating in interlaboratory comparisons, the obtained results should be assessed as satisfactory, and thus the laboratories confirm their competence. However, a wide scatter of the results of the open time measurement should be noted – 22 laboratories, the results of which were classified as “satisfactory”, obtained results from 0.1 N/mm2 to 1.0 N/mm2. Such a wide scatter of the results of open time measurements determined by the adhesion strength indicates that this method has too little accuracy, and it should not be used in the assessment and verification of constancy of performance of ceramic tile adhesives.
Why Non-HDL Cholesterol is Preferred over Apolipoprotein B-100 (Apo B)
Authors: Levinson Stanley
Published: January 2023

IMPORTANCE

Most studies have found that apo B-100 is a superior marker for Coronary risk (ASCVD) than non-HDL cholesterol (C). Usually, studies use multivariant analysis to compare indexes with single-point odds or risk ratios. In multivariant analysis when variables are highly correlated, they are difficult to interpret and the lesser may be excluded. As a result, effect sizes cannot be well compared. Receiver operator characteristic (ROC) curves provide a visual portrait of the accuracy and the diagnostic sensitivity and specificity at each decision level so that relative discrimination of each variable can be well compared. Since non-HDLC has distinct economic value, it is important to compare clinical value in an appropriate format.

OBJECTIVE

To compare outcomes from ROC analysis with routine one-point logistic regression.

DESIGN, SETTING, AND PARTICIPANTS

Lipoprotein variables alone and after correction for non-lipoprotein risk factors were compared from patients with and without significant ASCVD undergoing coronary angiography. 

MAIN OUTCOME MEASURES

The variables were assessed by standard logistic regression alone and by ROC curve analysis.

RESULTS

Although non-HDLC and apo B were stronger markers than LDLC, when examined by logistic regression, as a result of very strong collinearity, non-HDLC appeared weaker than LDLC in the presence of apo B, based on p-values. This was true when analyzed with and without non-lipid risk factors. When analyzed by ROC analysis, apo B and non-HDLC showed stronger C-statistics than LDLC and total C. At an appropriate apolipoprotein/lipid, decision level apo B showed about 6.1% greater specificity than non-HDLC. But, after adjustment for non-lipid risk factors, the c-statistics for apo B and non-HDLC were 0.64 and 0.63, respectively and there was little difference in specificity at a standard selected decision value.

CONCLUSION AND RELEVANCE

Except for persons with acquired or genetically determined hypercholesterolemia, the ten-year risk is calculated from an algorithm that includes non-lipid risk factors similar to those examined here. Based on this data, when assessed by the AHA/ACC ten-year screening algorithm, it is likely that non-HDLC would provide greater economic value than would apo B with similar clinical efficacy. Non-HDLC should be utilized as the preferred lipid marker.
Minimally Invasive Coronary Revascularization. Technical Aspects and Current Results
Authors: Fagu Albi , Shurdha Ormir , Caushi Nevila , Menkshi Ketjon , Hasi Dervish , Siqeca Meriton
Published: January 2023

Coronary artery bypass surgery has been for decades the gold standard for the treatment of coronary artery disease, especially in patients with 3-vessel disease. Despite the excellent results achieved through the application of this technique, problems related to median sternotomy and the use of cardiopulmonary bypass such as wound infections and cerebral stroke still play an important role in the postoperative course of these patients. Minimally invasive coronary revascularization techniques aim at reducing the rate of such complications while offering the same quality of revascularization.

Minimally invasive coronary surgery includes a set of coronary revascularization techniques that are completed without the use of cardiopulmonary bypass or through a left mini-thoracotomy at the level of the 4th or 5th intercostal space and aim at reducing the level of the aforementioned complications compared to the standard technique. Hybrid coronary revascularization is an alternative approach that combines surgical revascularization with percutaneous coronary interventions to extend the treatment spectrum even further. Through the application of these techniques, surgeons aim at minimizing the risk of infection of the surgical wound and significantly reduce the number of post-operative cerebral strokes. Also, numerous studies have shown that minimally invasive coronary surgery can offer better results in terms of duration of the mechanical ventilation, length of stay in intensive care, transfusions of blood products and consequently in reducing treatment costs.

Minimally invasive revascularization techniques are not only an important alternative to standard coronary surgery, but in the near future will constitute the standard treatment for this group of patients. This article aims to describe the techniques used to achieve minimally invasive coronary revascularization and to highlight the outcomes of the different approaches.CABG,
Study of population-genomic structure of Vyatka horses in interline aspect
Authors: Belousova Natal'ya , Bass Svetlana , Zinov'eva S. , Sorokin Sergey , Wilkinson Mitch
Published: January 2023

Abstract. The population-genomic structure of the Vyatka horses was studied in the context of 10 male genealogical lines bred in the breed. Purpose. Evaluation of the genetic and breeding potential of the Vyatka breed, as well as the influence of factory breeds. Methods. Isolation of DNA from the hair follicles of Vyatka horses (n = 38) was performed using “ExtraGene DNA Prep 2000” by allele-specific PCR. Statistical calculations of allele frequencies and the types of studied loci were performed using MS Excel 10 software. Results. The polymorphism of MSTN, GYS1, DMTR3, CAST, and PRLR genes in Vyatka breed lines was studied for the first time. According to the frequency of occurrence CAST G/A (0.472) and PRLR G/C (0.417), as well as the genotype MSTN T/T (0.579) is somewhat dominated by the heterozygous genotypes characteristic of local breeds. They revealed polysaccharide accumulation mutation PSSM1 (0.189), characteristic of draft horses, and the DMRT3 mutation (0.087), which determines the ability for a non-standard gait - amble, noted among Oryol trotters, which indicates the presence of draft and trotting blood in the lines carrying these alleles. MSTN/C and DMRT3/A alleles, which are not typical for aborigines, are noted in Znatok line, whose representatives are distinguished by a lightweight body type and productive movements. The carriers of the mutant defective GYS1 allele (PSSM1) were identified in five lines: Bob, Gabizon, Buran, Dobrik, and Malakhit. Genotyping of all used stallions for genes associated with economically useful traits will allow more efficient selection in the Vyatka breed and prevent the spread of unwanted alleles, which is especially important for small breeds. Scientific novelty. For the first time, an intrapopulation genomic analysis of the domestic horse breed was studied in the interline aspect, and the influence of factory breeds on certain genealogical lines was shown. The polymorphism of the calpastatin (CAST) and prolactin receptor (PRLR) genes has not previously been studied in horse breeding.

The purpose of the research is to study the impact of irrigation regimes on the temperature regime and productivity of spring wheat, the primary object of irrigation of the Northern Kulunda – southern light loamy chernozem. Methods. In microplot experiments, variants were tested with a lower moisture threshold of 80 %, 70, and 60 % of the lowest moisture capacity (LW) and a wetted layer thickness of 40 cm, 60, 80 cm, and with a differentiated wetted layer thickness depending on the phase of plant development. Methods for studying the temperature regime and the root system of plants are generally accepted. Scientific novelty. The optimal depth (0–40 cm) and the degree of moistening of the southern light loamy chernozem (HB-60 % HB) were determined, which ensure a favorable temperature regime of the soil under the conditions of Northern Kulunda and a high yield of spring wheat grain. Results. The temperature regime of the southern light loamy chernozem differs in the level of moisture, but remains favorable both during the day and during the growing season. Humidification of the 0–40 cm layer in the range of HB-70 % HB and HB-60% HB is the most optimal, feasible in practice and provides a conditional grain yield of 4.3–4.2 t/ha. To maintain such a regime of soil moisture, 4–7 irrigations are required with a total irrigation rate of 1700–2200 m3/ha, respectively. The largest share of wheat roots (62–76 % of the total mass) is concentrated in its upper part.

Abstract. The purpose is to establish the effectiveness of growing narrow–leaved lupine for grain in the conditions of the Sverdlovsk region. For the first time, new varieties of narrow-leaved lupin of the All-Russian Lupin Research Institute were used for ecological testing in these soil and climatic conditions in single-species crops when grown for grain. Research methodology and methods. The main method of conducting research was the laying of field experiments. Research in 2016–2017 they were conducted at the site of the Ural Research Institute, in 2021–2022 in the educational and experimental farm of the Ural State Agrarian University, located in the forest-steppe zone of the Sverdlovsk region. The main observations and records were carried out according to the methodology of the Institute of Feed. The yield was determined by the weight method with the selection of average samples. Results. In 2016–2017, 5 varieties of narrow-leaved lupine were studied: Raduzhnyy, Uzkolistnyy 53, Belozernyy 110, Smena, Vityaz’, and in 2021–2022, 3 varieties: Siderate 46, Bryanskiy kormovoy and Vityaz. All varieties of narrow-leaved lupine had side branches and beans on them before harvesting. The greatest number of lateral stems and beans was observed in the varieties Raduzhnyy and Vityaz’ in 2017 – 4.2–4.3 pcs. In 2016, the yield of narrow-leaved lupine grain from 1.13 to 1.54 t/ha was obtained on dark gray soil. In more favorable moisture conditions in 2017, the productivity of narrow-leaved lupine was 2-3 times higher than in the previous year in all varieties except for the Uzkolistnyy 53 variety. In acutely arid conditions 2021–2022 on podzolized chernozem, varieties of narrow-leaved lupine: Bryanskiy kormovoy, Vityaz’ and Siderat 46 provided grain yields from 1.34 t/ha for the Siderat 46 variety to 2.45 t/ha for the Vityaz’ variety. Scientific novelty. The effectiveness of growing new varieties of narrow-leaved lupine in the conditions of the Middle Urals was studied for the first time. Varieties have been established that allow obtaining high grain yields.

Abstract. The purpose of the research is to present the results of studies obtained in the long-term stationary experience of the Geographical Network of Experiments with Fertilizers of the Russian Federation on the effect of various methods of straw, crop residues and nitrogen fertilizers utilization on the humus state of leached black soil. Establish the effect of the systematic introduction of straw and crop residues on the content of total and labile humus in leached black soil, provide data on the fractional composition of humus. Methods. There were used conventional methods: total nitrogen by the method of indophenol greens, humus according to Tyurin in Simakov’s modification; fractional group composition according to Ponomareva and Plotnikova; labile carbon – by the release of humic substances during treatment with 0.1n NaOH, soil treatment with sodium pyrophosphate 0.1m Na4P2O7 (Dyakonova’s method) and hot water (Schulz’s method). Results. The results of studies obtained in a long-term stationary experiment on the study of the effect of straw and crop residues on the humus state of the soil are presented. It has been established that the annual introduction of straw and crop residues into the soil makes it possible to maintain the humus state of the leached black soil at the level of the initial content. Significant differences in the humus reserves in the arable soil layer according to the methods of utilization of organic residues were not revealed, they were assessed as very high. On a long fallow, humus reserves were high, on virgin lands they were ultra-high. The results of the studies showed that the fractional composition of fulvic acids depended on the method of using straw and stubble residues; the fractional composition of humic acids did not differ from the method of utilizing straw and stubble residues. A decrease in the content of total humus was revealed against the background of burning and removing straw and stubble, while an increase in its content was noted during the systematic plowing of post-harvest residues. Scientific novelty consists in changing the fractional-group composition of humus when using organic residues (straw, stubble) for the reproduction of soil organic matter.
Educational Role of the Student Cooperative

Published: January 2023

Student cooperatives were introduced into the educational system in 2018. However, they are not new. They functioned in the second half of the 20th century, mostly in vocational high schools, and then they gradually lost importance until they were completely shut down. Rapid technical and technological development and market laws, which make entrepreneurship imperative in the economic aspect of life, once again led to the need for student cooperatives. The student cooperative imposes itself as a unique, one could even say a universal form of student organization and work that contributes to the overall development of students. In accordance with the modern circumstances and challenges of the modern age, student cooperatives have become somewhat modernized. They encounter difficulties, but they successfully adapt to social trends. In all these complex circumstances, student cooperatives have achieved their main goal, which is the educational impact on students, which is its priority role. The aim of this paper is to corroborate and, relying on theoretical foundations and legal provisions, to point out the great training and educational importance of student cooperatives, which again has the effect of increasing the quality of education.

Background & Aims: Childbearing is important for the increase of population; for countries where fertility rate is low, it is important for sustainable development. The present study aims to evaluate the relationship of accountability and religious orientation with childbearing intention in women referred to comprehensive health centers in Yasouj, Iran. Materials & Methods: This descriptive and correlational study was conducted in 2019-2020 on 240 fertile married women aged 18-45 years referred to comprehensive health centers in Yasouj city, who were selected by a continuous sampling method. Inclusion criteria were no debilitating diseases, mental illnesses, or contraindication for pregnancy. A sociodemographic form, Harrison-Goff Accountability Scale, and Golriz and Baraheni’s Religious Attitude Scale were used to collect data. Data analysis was done in SPSS software, version 20 using chi-square test, independent t-test, and one-way analysis of variance. P<0.05 was statistically significant. Results: There was a negative and significant relationship between accountability and childbearing intention (P=0.036); the intention to have children was significantly lower in women with a higher accountability score. Religious orientation and its two dimensions (intrinsic and extrinsic orientation) had no significant relationship with childbearing intention. Age (P=0.001), length of marriage (P=0.001), and number of male children (P=0.011) had significant correlation with childbearing intention. Conclusion: In Yasuj city, the fertile women’s intention to have children decreases with the increase in their responsibilities, age, length of marriage, and number of male children. Therefore, it is recommended that these women be encouraged to have children at a younger age. It may be possible to encourage women with higher accountability to have children by teaching childbearing skills to them. Further studies are needed in this field.
