Efficiency as a tool for measuring law-making and its policy

In the scientific work, the author made an attempt to establish the methodological significance of the category «efficiency» in terms of the dimension of law-making and law-making policy. Attention is focused on the relevance of strengthening the scientific development of the methodology of studying law- making and its policy. It was emphasized that law-making requires systematic analysis, improvement of law-making mechanisms and the involvement of a wide range of experts to ensure the effective functioning of the legal system. Taking into account the constant changes in the social and political life of our country and the need to adapt legislation to European standards, law-making activity becomes an even more relevant phenomenon that not only needs its own scientific research, but also measurement for its effectiveness. Therefore, the relevance of the topic of this scientific work is determined both by the possibility of measuring the effectiveness of law-making, and by the necessity of such a measurement in order to provide a comprehensive assessment of the practice of law-making in Ukraine. The analysis of the views of scientists, which relate to the methodological significance of effectiveness as a tool for measuring the phenomena of legal reality, has been carried out. It is concluded that efficiency is a multidimensional tool that should establish the effectiveness of both directly law-making (on the micro-level) and the entire law-making policy (on the macro-level). It is noted that law-making and law-making policy can be studied from the point of view of their effectiveness, the results of which will have either a substantive nature (law-making effectiveness) or a strategic nature (law-making policy effectiveness). From the point of view of methodological significance, efficiency as a tool for measuring law-making and law-making policy is an independent: 1) a way of measuring indicators that reflect the result of the functioning of law-making or law-making policy; 2) a means of identifying and characterizing the role and purpose of law-making and its policy in socio-political and legal aspects; 3) a mechanism for identifying deficiencies in law-making activity and the content of law-making policy; 4) a prerequisite for substantiating ways of improving law-making activity and the content of law-making policy.

Establishing the reliability of metrics extracted from long-form recordings using LENA and the ACLEW pipeline.

Long-form audio recordings are increasingly used to study individual variation, group differences, and many other topics in theoretical and applied fields of developmental science, particularly for the description of children's language input (typically speech from adults) and children's language output (ranging from babble to sentences). The proprietary LENA software has been available for over a decade, and with it, users have come to rely on derived metrics like adult word count (AWC) and child vocalization counts (CVC), which have also more recently been derived using an open-source alternative, the ACLEW pipeline. Yet, there is relatively little work assessing the reliability of long-form metrics in terms of the stability of individual differences across time. Filling this gap, we analyzed eight spoken-language datasets: four from North American English-learning infants, and one each from British English-, French-, American English-/Spanish-, and Quechua-/Spanish-learning infants. The audio data were analyzed using two types of processing software: LENA and the ACLEW open-source pipeline. When all corpora were included, we found relatively low to moderate reliability (across multiple recordings, intraclass correlation coefficient attributed to the child identity [Child ICC], was < 50% for most metrics). There were few differences between the two pipelines. Exploratory analyses suggested some differences as a function of child age and corpora. These findings suggest that, while reliability is likely sufficient for various group-level analyses, caution is needed when using either LENA or ACLEW tools to study individual variation. We also encourage improvement of extant tools, specifically targeting accurate measurement of individual variation.

Methodological and practical recommendations for improving the quality of forecasts of innovative development of science, technology and engineering

The generated long-term forecasts for the development of science, technology and engineering are widely used to determine priority areas of scientific and technological development. In an unstable economic situation, it is important to ensure the quality of forecasts, since they determine the priorities and priority areas for financing scientific and technological development projects. Therefore, the problem of improving the quality characteristics of long-term forecasts for the development of science, technology and engineering is relevant. The authors set the goal of determining a set of measures to improve. the quality of the generated forecasts, taking into account modern conditions of economic development, characterized by instability and sanctions restrictions. For this purpose, a systematic and integrated approach to the development of proposals is used. Complexity lies in a comprehensive analysis of the factors influencing the forecast results, and proposals are formed on the basis of a systematic account of the component indicators of forecast quality and mutual connections. The paper presents proposals to improve the accuracy, usefulness, information content, completeness and reliability of forecasts. The similarities and differences between the proposals and the existing ones are shown, and the directions for applying the developed recommendations by the participants in the formation of long-term forecasts for the development of science, technology and engineering are also revealed. The novelty of the article lies in the fact that the authors, based on the use of systematic and integrated approaches, have identified the main methodological and practical proposals for improving the quality characteristics of long-term forecasts for the development of science, technology and engineering. This will help improve the quality of scientific and technological forecasts and effectively spend budget funds to finance new projects formed on the basis of forecasting results.

Probabilistic Seismic Hazard Assessment of Lisbon (Portugal)

The 1755 Lisbon earthquake holds significant historical importance in Portuguese history. The subsequent tsunami resulted in extensive destruction and damage, affecting not only Lisbon but also other regions of Portugal, Spain, and North Africa. This significant and hazardous event led to an increase in awareness about earthquake and tsunami risks, not only within Portugal but throughout Europe. This heightened awareness facilitated advancements in scientific developments, including design codes, standards, and earthquake engineering. However, recent studies focusing on hazard assessment for Lisbon are limited. For this reason, this paper aims to present a comprehensive probabilistic seismic hazard analysis (PSHA) for the Lisbon metropolitan area. The first stage of PSHA involves defining applicable and active seismic source models (area and line sources) within the study area. Subsequently, historical and instrumental earthquake records are collected to build a homogenized earthquake catalog, utilizing both global and local earthquake databases. Following this, the completeness level of the earthquake catalog is tested. By incorporating suitable ground motion models to the region and local soil characteristics, seismic hazard maps for various return periods and hazard curves in terms of peak ground acceleration (PGA) are developed. The findings based on the area source model agree with existing literature, indicating PGA values ranging from 0.3 g to 0.9 g, 0.2 g to 0.7 g, 0.2 g to 0.5 g, and 0.1 g to 0.3 g for return periods of 2475, 975, 475, and 50 years, respectively.

Stages of formation of artistic skills of art students

The author's elaboration of the stages of formation of artistic and visual skills of students of higher education institutions in the process of creative activity is disclosed and presented in the article for general consideration. The analysis of scientific, psychological-pedagogical and educational-methodical achievements of scientists was carried out in order to specify the content of the concept of "skill", classification of types and stages of the process of formation of skills. The subject of our research "artistic skills" is presented on the basis of thorough theoretical studies of scientists, the idea of ​​the concept of professional and artistic skills of fine art teachers is expanded, a generalization is made regarding the diversity of their types, to which we include artistic-technical, artistic-methodical, artistic-workshop and artistic - visual skills, which are also divided into their own subspecies. In the process of scientific research, the concept of psychological and pedagogical foundations of "formation of artistic skills" and the "exercise" method of generalizing its types and kinds were considered. A list of effective means of the system of educational tasks for art students of higher educational institutions is proposed for consideration, namely, technical methods and techniques in working with soft materials, such as: method - hatching, extinguishing, mixing colors, etc.; technique - side shading, shading, dry washing, wet brush, pen and others. Based on modern theoretical and scientific developments and conceptual ideas of scientists regarding the procedure of "formation of artistic skills", relying on our own professional experience, we reveal the essence and expediency of each of the six stages: organizational, diagnostic, analytical, systematic, synthetic and automation. In accordance with the presented stages, goals, tasks, methods, ways, rules, advantages and disadvantages of their application in practice are determined. The formation of students' artistic skills is due to the use of a number of appropriate methods: scientifically pedagogical - organizational, communicative, instruction, demonstration, illustration, explanation, master class, research, control, verification, current, forecasting, competition, observation and evaluation; personally developed artistic and technical methods that contribute to the effective and rapid mastering of the specifics of performing new technical actions by students in artistic educational activities - "experimental-diagnostic", "differential-constructive", "constructive division", "constructive combination", "holistic-constructive" ", "variable-interval"

A comprehensive review on the development of chiral Cu, Ni, and Zn complexes as pharmaceutical agents over the past decades: Synthesis, molecular structure and biological activity.

Chirality is a fundamental and widespread geometric structural property in living organisms that most biomacromolecules including nucleic acids, proteins and enzymes, possess. Consequently, the development of chiral drugs capable of binding specific targets have gradually gained wide attention in recent decades due to their selective effects on a broad spectrum of biological events ranging from cell metabolism to cell fate. In this context, the synthesis of chiral compounds as promising therapeutic candidates has assumed a major role in drug discovery. Among them, chiral metal complexes have attracted considerable interest due to their unique and intriguing structural features that could enable overcoming side effects and drug-resistance phenomena of metal-based drugs currently in the market such as cisplatin. In the current scenario, an in-depth overview of non-platinum chiral complexes needs to be presented and carried forward. Therefore, in this perspective article, an update of the scientific development of bioactive chiral copper, zinc and nickel complexes have been reported since they have not been thoroughly reviewed so far. Specifically, we focused the article mainly on metal complexes containing chiral ligands (type 2 chirality) as in literature they are more numerous than those with chirality at the metal center (type 1 chirality). Herein, not only their biological activity but also their mechanism of action is summarized. Furthermore, in the final section of the article we have highlighted copper-based complexes as those with a superior biological activity profile and greater prospects for development as a drug.

Tracing scientific and technological development in genetically modified crops.

Genetically Modified (GM) Organisms have been used in various domains since their introduction in the 1980s. According to ISAAA data, the use of GM crops in agriculture has also increased significantly in the past 30years. However, even after 3 decades of commercialisation, GM crops are still surrounded with controversies with different countries adopting varying approaches to their introduction in the consumer markets, owing to different stances of various stakeholders. Motivated by this multitude of opinions, and absence of knowledge mapping, this study has undertaken scientometric analysis of the publication (Web of Science) and patent (Lens.org) data about genetically modified technology use in agriculture to explore the changing knowledge patterns and technological advancements in the area. It explores both scientific and technological perspectives regarding the use of Genetically Modified Crops, by using publication as well as patent data. The findings of this study highlight the major domains of research, technology development, and leading actors in the ecosystem. These findings can be helpful in taking effective policy decisions, and furthering the research activities. It presents a composite picture using both publications and patent data. Further, it will be of utility to explore the other technologies which are replacing GM technology in agriculture in future studies.

BUILDING AND CONSTRUCTION RECONSTRUCTION DESIGN

In order to create the necessary conditions for life and development of society, the production of various products are organized. The nomenclature and consumer qualities of the produced products are determined by the level of scientific and technical development, economic and social living conditions. For the production of products, houses and buildings are erected, which are equipped with certain means of production. The term of functioning of means of production is due to physical and moral wear and tear of machines and mechanisms. Buildings and structures in, which means production are located and function also age physically and morally, although this aging occurs slower than the means of production.Scientific and technical progress is currently characterized by a faster onset of wear and tear of the nomenclature of manufactured products. In addition, in connection with the changes taking place in society, the nomenclature of manufactured products replaced. The problem of retooling the functioning industry (replacing morally or physically outdated means of production, the emergence of need to produce new types of products) arose before humanity a long time ago.Under reconstruction - the production of works, which carried out according to single project:- with a change in volume-planning decisions;- replacement or strengthening of existing structures;- demolition of existing and construction of new structures related to the operation of technological equipment;- with the replacement of obsolete or physically worn equipment;- with mechanization, production automation, etc. When carrying out the reconstruction of the main production facility, as a rule, significant volumes of work are always performed on auxiliary and service facilities.Reconstruction also includes the construction of new workshops and facilities instead of those, which being liquidated, the further operation of which is deemed impractical due to technical and economic conditions. They can be erected both on free territories and on areas vacated as a result of the liquidation (demolition) of the object.Technical re-equipment is clear as the implementation of a set of measures in accordance with the technical development plan of the enterprise according to projects and estimates for individual objects and types of work (without expanding existing production areas) to raise the technical level of individual areas of production, aggregates, and installations to modern requirements by introducing new equipment and technology, mechanization and automation of production processes, modernization and replacement of obsolete or physically worn equipment with new, more productive ones.Sometimes technical rearmament considered as a type of reconstruction with a relatively small amount of construction and installation work. As it is not difficult to see from the given definitions, new construction and expansion are in fact new construction, while the difference between them is only in the conditions of execution of works. Expansion of construction is carried out in difficult (compressed) conditions. Technical rearmament, as it was emphasized, mainly involves the organization of the dismantling of the old and the installation of new equipment on the existing foundations.In the future, the main attention will be paid to the issues of actual reconstruction, namely:- organization of works related to the strengthening of existing building structures, their replacement with temporary transfer of loads;- replacement of beams and trusses in areas of the covering located in areas difficult to reach for installation cranes;- by increasing the pitch of the columns without disassembly.

Adoption of Appropriate Agricultural Model for Food Security in Guiping Town, Renshou County, China

Agriculture is an important foundation for a country's economic and social development and stability, and we must firmly give agricultural development a prominent position of priority. Guiping Town is a typical agricultural town in hilly area. The roads, water conservancy facilities and other agricultural production conditions are relatively insufficient, which restricts the development of characteristic and large-scale agriculture. In recent years, the national policy requires all localities to focus on the overall requirements of achieving self-sufficiency in domestic resources and ensuring food security, and must work hard in promoting farmland protection and control, sustainable agricultural development, and strengthening agricultural production support, so as to continuously consolidate and improve the level of agricultural scientific development. Based on the actual situation of Guiping, this paper, through a large number of interviews and surveys, literature review and scientific analysis methods, deeply explores the economic and environmental sustainability, adequate farmer income, future-oriented production capacity, improved food security and social sustainability, and finds a way out in agricultural innovation and development. Gradually explored a good agricultural development situation that basically realized the use of good land and grain and should be planted.

A critical analysis of government grants accounting approaches. Part 1

Subject. This article discusses the theoretical, historical and methodological particularities of State assistance accounting, including the socio-economic relations that have developed between companies, developers of accounting standards and the academic community. Objectives. The article aims to critically characterize approaches to State assistance accounting, show the theoretical inconsistency of the International Financial Reporting Standard (IAS) 20 – Accounting for Government Grants and Disclosure of Government Assistance, and choose the most appropriate method that corresponds to the guideline scientific concepts. Methods. The research is speculative. For the study, I used the dialectical method of scientific knowledge, the method of collecting theoretical and regulatory information, the method of formalization, as well as analysis, synthesis, observation, and comparison. Results. The scientific novelty lies in the generalization and characterization of five approaches to the accounting for State assistance. The article substantiates that State assistance should be recognized as part of liabilities if and only if there are current and/or future conditions that impose obligations on the organization to receive State assistance, otherwise it should be recognized exclusively as part of equity. It is found that the background of these standards in the area of accounting for State assistance is the result of lobbying companies to increase net income. Conclusions and Relevance. The results of the study call into question the acceptability of the theoretical foundation of IAS 20. The results of the study are primarily intended for the accounting scientific community and developers of accounting standards.

Обновление стратегического вектора развития искусственного интеллекта в России: правовые аспекты

The systematic development of artificial intelligence in Russia began in 2019 with the approval of the National Strategy for the Development of Artificial Intelligence for the period until 2030. For the first time, it reflects the state’s comprehensive approach to the named institute: key concepts are defined, goals, main tasks, and priority areas for the use of artificial intelligence technologies are established. Their legal regulation was based on the “soft law” model. The active introduction of artificial intelligence into the economy, as well as new scientific developments, have led to a change in its strategic vector as early as 2024. The article analyzes the updated National Strategy, focusing on the new section that consolidates the creation of a system of legal regulation of artificial intelligence. A critical assessment is substantiated regarding the lack of forward movement in regulation from “soft law” to mandatory legislative norms.

Thrombospondins: Conserved mediators and modulators of metazoan extracellular matrix.

This review provides a personal overview of significant scientific developments in the thrombospondin field during the course of my career. Thrombospondins are multidomain, multimeric, calcium-binding extracellular glycoproteins with context-specific roles in tissue organisation. They act at cell surfaces and within ECM to regulate cell phenotype and signalling, differentiation and assembly of collagenous ECM, along with tissue-specific roles in cartilage, angiogenesis and synaptic function. More recently, intracellular, homeostatic roles have also been identified. Resolution of structures for the major domains of mammalian thrombospondins has facilitated major advances in understanding thrombospondin biology from molecule to tissue; for example, in illuminating molecular consequences of disease-causing coding mutations in human pseudoachrondroplasia. Although principally studied in vertebrates, thrombospondins are amongst the most ancient of animal ECM proteins, with many invertebrates encoding a single thrombospondin and the thrombospondin gene family of vertebrates originating through gene duplications. Moreover, thrombospondins form one branch of a thrombospondin superfamily that debuted at the origin of metazoans. The super-family includes additional sub-groups, present only in invertebrates, that differ in N-terminal domain organisation, share the distinctive TSP C-terminal region domain architecture and, to the limited extent studied to date, apparently contribute to tissue development and organisation. Finally, major lines of translational research are discussed, related to fibrosis; TSP1, TSP2 and inhibition of angiogenesis; and the alleviation of chronic cartilage tissue pathologies in pseudoachrondroplasia.

Photoneuroendocrine, circadian and seasonal systems: from photoneuroendocrinology to circadian biology and medicine.

This contribution highlights the scientific development of two intertwined disciplines, photoneuroendocrinology and circadian biology. Photoneuroendocrinology has focused on nonvisual photoreceptors that translate light stimuli into neuroendocrine signals and serve rhythm entrainment. Nonvisual photoreceptors first described in the pineal complex and brain of nonmammalian species are luminance detectors. In the pineal, they control the formation of melatonin, the highly conserved hormone of darkness which is synthesized night by night. Pinealocytes endowed with both photoreceptive and neuroendocrine capacities function as "photoneuroendocrine cells." In adult mammals, nonvisual photoreceptors controlling pineal melatonin biosynthesis and pupillary reflexes are absent from the pineal and brain and occur only in the inner layer of the retina. Encephalic photoreceptors regulate seasonal rhythms, such as the reproductive cycle. They are concentrated in circumventricular organs, the lateral septal organ and the paraventricular organ, and represent cerebrospinal fluid contacting neurons. Nonvisual photoreceptors employ different photopigments such as melanopsin, pinopsin, parapinopsin, neuropsin, and vertebrate ancient opsin. After identification of clock genes and molecular clockwork, circadian biology became cutting-edge research with a focus on rhythm generation. Molecular clockworks tick in every nucleated cell and, as shown in mammals, they drive the expression of more than 3000 genes and are of overall importance for regulation of cell proliferation and metabolism. The mammalian circadian system is hierarchically organized; the central rhythm generator is located in the suprachiasmatic nuclei which entrain peripheral circadian oscillators via multiple neuronal and neuroendocrine pathways. Disrupted molecular clockworks may cause various diseases, and investigations of this interplay will establish a new discipline: circadian medicine.

PROPEL: a scalable model for postbaccalaureate training to promote diversity in the biomedical workforce.

Promoting diversity in the scientific workforce is crucial for harnessing the potential of available talent and ensuring equitable access to Science, Technology, Engineering, Mathematics, and Medicine (STEM-M) careers. We have developed an innovative program called Postbaccalaureate Research Opportunity to Promote Equity in Learning (PROPEL) that provides scientific and career development training for postbaccalaureate scholars from historically excluded backgrounds in STEM-M fields with an interest in pursuing a PhD or MD/PhD degree. Our program is distinct from other postbaccalaureate programs in that scholars are hired by individual labs rather than funded centrally by the program. This funding mechanism removes the idea that central funding is necessary to encourage faculty to train diverse scholars and allows the program to scale dynamically according to the needs of the scientific community. The PROPEL program started in 2020 with six scholars and has since grown to an enrollment of over 100, making it the largest postbaccalaureate program for biomedical research in the country. Here, we describe the program structure and curriculum, our strategy for recruitment, the enrollment trends, the program demographics, metrics of scholar engagement, and outcomes for scholars who completed the program in 2023. Our experience demonstrates the strong demand from both scholars and faculty for programming of this type and describes the feasibility of implementation.

Quality of education and mental health of pharmacy students in Poland.

Pharmacists in the healthcare system play an important role in providing safe, optimal pharmacotherapy and patient education. During their studies, in which they acquire the competencies to fulfill the pharmacist's future tasks, pharmacy students are exposed to significant stress and pressure. This study aims to demonstrate the extent to which the unique demands and obstacles of Polish pharmacy schools contribute to the deterioration of students' mental health and overall wellbeing. A cross-sectional study of 420 pharmacy students in Poland evaluates the quality of education at Polish universities and presents the impact of studying on students' mental health. The criteria for choosing the field of study, the particular major, the university itself, the quality of education, the academic work, and their impact on students' wellbeing were evaluated. The evaluation of the quality of education was influenced by mentoring and tutoring at the university. Pearson's ÷2 test and principal component analysis (PCA) were used in the statistical analyses. Unequal treatment of pharmacy students relative to students in other areas of medical study was marked by 90.2% of respondents, and opportunities for scientific development were indicated as good by 60.0% of pharmacy students. It was shown that 82.1% of the students rated studying as very stressful; the level of test difficulty and exams, as well as an inadequate level of knowledge imparted during classes contributed to this response. According to 75.2% of the respondents, the perceived stress had long-term effects in the form of anxiety and depression, with the need for pharmacotherapy. It was shown that studies contributed to the onset and/or exacerbation of depressive and anxiety symptoms. The results indicate the need to support psychological care and extend it to to pharmacy students.

Neural network classification of technological development projects in Russian companies: Perspectives of extreme project management

To achieve the goals of sustainable socio-economic development and ensure the technological sovereignty of the Russian Federation, it is critically important to choose effective methods of technological project management. The article develops a novel toolkit for neural network classification of technological development projects in Russian companies and justifies the use of extreme project management to such endeavors. The methodological framework resides in the concepts of project lifecycle management and data mining. The study employed the following research methods: textual analysis of project documentation using large language models, and intelligent project classification based on two-dimensional projection of multidimensional clusters using Orange Data Mining. The research draws upon regulatory documents in the field of Russia’s scientific and technological development and open databases on Russian companies’ projects. The work proposes a new neural network classification toolkit based on a large language model. We have found that most development projects related to critical and end-to-end technologies are characterized by low certainty of goals and solutions, which necessitates applying extreme approaches to manage them. The findings can be used by Russian companies for reasoning the choice of a project management model, as well as by experts when evaluating technological development projects.

MODEL OF SPARE PARTS INVENTORY MANAGEMENT IN THE SUPPLY SYSTEM: THE CASE OF THE ‘OLL TRAK PARTS’ COMPANY

The article identifies the relevance of the problem of optimisation of material reserves of a company and their effective management, as the state of existing reserves has a decisive impact on the competitiveness of the company, its financial condition, and the corresponding performance results. It allows the formulation of the research objective in this development. It is a given that inventory management technology is an integral part of the management system of any manufacturing and trading company. The efficiency of these companies depends on such critical criteria as the number of costs incurred for inventory management. Traditional indicators, such as inventory volume, resource turnover, and continuity of supply, cannot be used in isolation to accurately measure the extent to which an inventory management system is improving since they are part of the overall cost criterion. The article examines scientific developments of theoretical foundations for implementing rational solutions in the supply chain, where the authors use modern research methods and approaches. After analysing these studies, we identify the main problematic issues: determining a rational way of servicing orders by the core production warehouse systems, organising an efficient product supply form, and developing rational inventory management technologies throughout the entire product supply chain. We create a structural model of interaction between the warehouse system of the ‘OLL TRAK PARTS’ company and suppliers and customers, formed with the participation of certain parties in all relevant operations. The structure of stocks accounts for the customer’s needs in a multi-nomenclature offer of spare parts for trucks, cars, and agricultural machinery supplied by ‘OLL TRAK PARTS’. The authors build a mathematical model of spare parts inventory management under limited demand conditions, which considers the following parameters of influence: the period for ordering spare parts, the cost of supplying ordered spare parts, and the cost of storing one unit of spare parts inventory. To achieve maximum measurement accuracy with a minimum number of trials and to maintain the statistical reliability of the results, we develop a full-factor experiment plan for three input parameters with three levels of values, consisting of 27 series of trials. The experiment allowed us to model the change in minimum costs with different order volumes of spare parts. Based on the results of the regression analysis of the obtained values of the estimated indicator, we determined the type of regression model – a linear form with a non-zero coefficient. Keywords: model, warehouse, system, logistics, interaction.
