DIALEKTIKA PENCERAHAN BUDDHISME
Authors: Arimbawa I Komang Suastika
Published: November 2022

Buddhism is one of the heterodox schools of Indian philosophy, taught by Siddārtha around the VI century BC. His teachings aim to lead his followers to nirvana, by building universal values ​​that are not compartmentalized, so that they are free from the varna system. However, after the influence of Tantra in the VII century AD, Buddhist philosophy turned to Buddhism. The problem to be analyzed in this article is “what is the dialectic of enlightenment Buddhism?” The theoretical concept used in this article is hermeneutics. This article uses qualitative research methods. The results of the analysis in this article are that the teachings of Buddhist philosophy are universal, outside of certain religions and castes. Meanwhile, Buddhism's teachings are only embraced by its followers (limited in nature). However, what connects the two is the teaching of ethics. Where the goal is to free mankind from suffering. Thus, the relationship between the three forms a dialectic.

Backstepping-Based Steering Control for Spacecraft Attitude Control Using Two-Skewed Control Moment Gyroscopes
Authors: Kojima Hirohisa
Published: November 2022

Numerous control methods that use two reaction wheels have been proposed for the underactuated control problem. However, few studies have applied two single-gimbal control moment gyroscopes (SGCMGs) to the three-axis attitude control problem. In this study, under the assumption that the total initial angular momentum is zero, a steering control law for the three-axis attitude maneuvers of a spacecraft with an array of two-skewed SGCMGs is designed using the backstepping technique without setting a constraint on the range of gimbal angles. The spacecraft attitude is expressed in terms of the [Formula: see text] parameters, which are suitable for the underactuated attitude control problem. The control gains are appropriately chosen to guarantee controller stability. The proposed steering control law is validated through numerical simulations. The results show that the proposed steering control law can achieve a shorter settling time than that obtained from a control law with a constraint on the range of gimbal angles.
Potensi Ekstrak Ubi Gadung (Dioscorea hispida Dennst.) dan Ekstrak Gulma Babadotan (Ageratum conyzoides L.) untuk Pengendalian Hama Penghisap Buah Kakao (Helopeltis spp.) di Laboratorium
Authors: Supriyatdi Dedi , Fernando Adam , Sari Sismita
Published: November 2022

Cocoa pod sucking (Helopeltis spp.) is one of the pests that causes a productivity decrease of cocoa pod in Indonesia. In terms of control, many farmers in Indonesia are still using synthetic insecticides that are not environmentally friendly, so intoxicating yam (Dioscorea hispida Dennts) and tropical whiteweed (Ageratum conyzoides L.) are used as botanical insecticide that are environmentally friendly. The objective of this research is to determine the effect of botanical insecticide that made of intoxicating yam extract, tropical whiteweed extract, and mixed extract of intoxicating yam and tropical whiteweed on the mortality of cocoa pod sucking pests. This research was carried out from November 2020 to February 2021, at the Plant Laboratory II Estate Crop Department, Politeknik Negeri Lampung. The research used a Randomized Block Design (RBD) consisting of four treatments, namely: P0 (control), P1 (intoxicating yam extract), P2 (tropical whiteweed extract), and P3 (combination of both extracts), which were repeated six times. The highest mortality of cocoa pod sucking pests was found in treatment P1 (72.73%). The mortality of cocoa pod sucking pest was caused by extract of intoxicating yam which contains the active ingredients of saponins, alkaloids, flavonoids, and cyanide which enter the digestive system of the cocoa pod sucking pest as stomach poisons, resulting in the death of the cocoa pod sucking pest. Based on the results of the research, it was concluded that intoxicating yam extract is the most potential as botanical insectiside for cocoa pod sucking pest.

This study aims to determine the best dose of mycorrhizal biological fertilizer for palm oil seedling growth of DxP Simalungun and DxP Sriwijaya 2 varieties in the pre-nursery stage. This research was carried out by the shade house of the Faculty of Agriculture, Sriwijaya University, Indralaya, Ogan Ilir, from October 2020 to January 2021. The study used the Completely Randomized Design method consisting of eight treatments and four replications, in which there were three plants in each experimental unit. The treatment provided consists of A (Simalungun without mycorrhizal), B (Simalungun given 5 g of mycorrhizal), C (Simalungun given 10 g of mycorrhizal), D (Simalungun given 15 g of mycorrhizal), E (Sriwijaya 2 without mycorrhizal), F (Sriwijaya 2 given 5 g of mycorrhizal), G (Sriwijaya 2 given 10 g of mycorrhizal), and H (Sriwijaya 2 was given 15 g of mycorrhizal). The results showed that the treatment of mycorrhizal biofertilizer with a dose of 5 g is the best treatment to the height of seedlings, the number of leaves, the leaf greenness index, the total leaf area, the diameter of the seedlings, the number of roots, the length of roots, and the dry weight of seedlings. The Sriwijaya 2 variety is more responsive to the provision of mycorrhizal biofertilizers.
Standardization of Taqwa (Piety) Scale for Muslims: An Exploratory Study
Authors: Nazam Fauzia , Husain Akbar , Gull Mubashir
Published: November 2022

Taqwa (piety) is a construct in Islamic psychology. It correlates with a large number of behavior such as sustainable capacity building, Islamic leadership, employees’ happiness, and workplace deviance. But the earlier studies have failed to capture the assessment of taqwa from the Qur'anic perspective. In the present study, an attempt is made to standardize a taqwa scale. In the first phase, a pool of 30 items was generated for each of the three domains of the construct (Faith in God, Love for God, and Fear of God), and subject matter experts judge the items’ content for the relevance, clarity, and simplicity on a 4 point Likert rating scale. Item content validity index and interrater reliability of each item were calculated. In the final version, 28 items remained content valid. A total of 229 Muslim students purposively drawn, completed the measure. The mean age of the participants was 22.66 (SD= 1.84). The Taqwa Scale consisted of twelve items with 6 point-Likert rating scale. Exploratory Factor Analysis yielded three factors, namely, faith in God (7 items), love for God (3 items), and fear of God (2 items). Content validity, inter-rater reliability, factorial validity, composite reliability, and construct validity provide strong evidence of the reliability and validity of the taqwa Scale.

An article about the famous Far Eastern forester, Doctor of Biological Sciences, Professor, Honored Forester of Russia Yuri Ivanovich Manko (25.11.1931 – 19.02.2021). After graduating from the Siberian Forestry Institute in 1954, he was assigned to the Far Eastern branch of the SB Academy of Sciences of the USSR named after V.L. Komarov and taken to the Department of Botany and Plant Science in the Laboratory of Forestry, which was organized and headed by Professor Boris Pavlovich Kolesnikov. In 1966, already as part of the Biology and Soil Sience Institute, established in 1962, the laboratory was reorganized into a non-structural forest Department. In 1962, Yu.I. Manko defended his Candidate thesis «Natural regeneration of fir-spruce forests of the northern half of Sikhote-Alin and some issues of their structure and development», in 1985 – his doctoral dissertation «Ayan spruce (distribution, biology, classification of forest types, features of age structure and dynamics of phytocenoses». The scientific heritage of Yuri Ivanovich exceeds 330 publications on forestry, botany, soil science, botanical geography, history of science, nature conservation issues. Yuri Ivanovich Manko throughout his scientific activity developed and promoted the «genetic» or «geographical-genetic» direction of forest typology closely related to the forest formation process, which was developed on the basis of the scientific heritage of B.A. Ivashkevich-B.P. Kolesnikov. He supplemented the theory of the forest formation process by characterizing the zonal features of this process in the area of the Ayan spruce with autogenous vegetation development and exogenous destructive effects. They were shown that the spectrum of particular forest-forming processes is specific for various sub-formations and geographical facies, and their dynamics depends on geomorphological conditions and the speed of modern reliefforming processes. The name of Yuri Ivanovich Manko is inscribed in the history of Far Eastern science as an outstanding researcher of forests.
Nietzsche e a técnica da memória
Authors: Feiler Adilson
Published: November 2022

As principais considerações acerca das técnicas da memória, expostas no decorrer do artigo, estão focalizadas no acento que concedem ao aparato moral institucional, responsável, em grande parte, pela decadência da cultura. A investigação aponta para a hipótese de que neste projeto nietzschiano mnemónico vigora uma aporia: a de permanecer na esfera da afirmação da técnica, ou seja, da afirmação de todos aqueles procedimentos e aparatos centrados no modo pelo qual algo se realiza. Se, por um lado, Nietzsche questiona todos os mecanismos técnicos, a saber àqueles relativos aos estabelecimentos de ensino por outro, ele não ultrapassa esta esfera, afirma a técnica através dos mecanismos do esquecimento, ao questionar as técnicas de memória. Diante disso, se pergunta: em que medida os escritos de Nietzsche inspiram uma reflexão profícua para pensar a técnica e sua aplicação à memória, de modo a alavancar a cultura, pela superação das tendências da pressa, da especialização e da massificação.

FIBULAE OF THE DNIEPER FOREST-STEPPE LEFT BANK REGION AND THE DON REGION DURING THE EARLY ROMAN PERIOD. ISSUES OF THE CONTACTS MAINTAINED BY THE SEDENTARY POPULATION
Authors: Обломский А. М.
Published: November 2022

В статье рассмотрены фибулы раннеримского времени, которые найдены на памятниках оседлого населения позднезарубинецкого культурно-хронологического горизонта Днепровского лесостепного Левобережья и бассейна р. Хопёр, а также позднескифской археологической культуры Верхнего Подонья. В результате выяснилось, что время близкого соседства позднезарубинецкого и позднескифского населения охватывает в широких рамках середину I - II в., а в узких - вторую половину II в. Набор фибул демонстрирует разное направление связей: позднескифский - с Северным Причерноморьем и сарматами, позднезару-бинецкий - с другими культурными группами этого горизонта, Средней Европой, возможно, с Юго-Восточной Прибалтикой. Создается ощущение, что тесных контактов между синхронными позднезарубинецкими группировками и позднескифским населением Верхнего Подонья не было, хотя этот вывод требует проверки и по другим материалам.

The paper reviews fibulae of the Early Roman period found at the sites of the sedentary population attributed to the Late Zarubintsy cultural and chronological horizon in the Dnieper forest-steppe Left Bank region and the Khoper river as well as the Late Scythian archaeological culture in the Upper Don region. It was found that the period when the Late Zarubintsy population lived side by side with the Late Scythian population can be defined broadly as the middle of the 1st-2nd centuries and narrowly as the second half of the 2nd century. Sets of fibulae point to various contacts with areas outside the studied region, for example, the Late Scythian set points to contacts with the North Pontic region and Sarmatians, while the Late Zarubintsy set demonstrates that this population maintained links with other cultural groups of this horizon, Central Europe, and maybe, Southeastern Baltics region. It seems that there were no close contacts between contemporary Late Zarubintsy groups and the Late Scythian population inhabiting the Upper Don region, though this conclusion needs to be verified based on other materials as well.
THE GLASS BEAKER WITH APPLIQUE SNAKE-THREAD DECORATION FROM FRONTOVOYE 3
Authors: Голофаст Л. А. , Свиридов А. Н.
Published: November 2022

При раскопках грунтового могильника Фронтовое 3 в пригороде Севастополя (Юго-Западный Крым) в захоронении конца II - середины III в. был обнаружен уникальный для Крыма импортный стеклянный кубок с растительным орнаментом, выполненным накладными «змеевидными» нитями. Такой орнамент, известный под названием «snake-thread decoration» или «Schlagenfaden Glas», характерен для продукции Восточного Средиземноморья, Кёльна (и, возможно, ряда других западноевропейских мастерских) и Паннонии. Посуда с такой орнаментацией относится к разряду предметов роскоши и была неотъемлемой частью сервировки стола сельской и городской элиты и, как правило, встречается в богатых захоронениях. Комплекс данных о форме и характере декора сосуда из Фронтового не позволяет определить точное место его изготовления, однако он, вероятно, относится к продукции одной из европейских мастерских. Его находка в одном из захоронений Фронтового хорошо объяснима: в рассматриваемый период юг и часть юго-запада Таврики находились под контролем римской военной администрации, и ее экономические связи с Херсонесом существенно расширились.

During the excavations of the in-ground Frontovoye-3 cemetery in a suburb of Sevastopol (southwestern Crimea) an imported glass beaker with a floral ornament made with applique snake-threads was found. The beaker is unique for the Crimea. It was discovered in a grave dating to the end of the 2nd - mid 3rd centuries. This decoration known as snake-thread decoration or Schlagenfaden Glas is typical for the products from the eastern Mediterranean, Cologne (and, possibly, a number of other West European workshops) and Pannonia. Vessels with such ornament were luxury items used as table settings in houses of rural and urban elite; as a rule, they are found in rich burials. The dataset on the form and nature of the decoration on the beaker from Frontovoye does not make it possible to say where exactly it was produced; however, it is likely that it was made in a European workshop. Its discovery in one of the Frontovoye graves can be easily explained. During the discussed period the southern part and some areas in the southwestern part of Taurica were under control of the Roman military administrations and its economic links with Chersoneses were substantially expanded.
ON THE SPECIAL FEATURES OF THE IMAGES OF WATERFOWL ON THE RHOMB-PIT WARE VESSELS FROM THE EASTERN PART OF THE BALTIC SEA BASIN
Authors: Жульников А. М.
Published: November 2022

В статье рассматриваются пространственные и стилистические особенности изображений, выполненных ямками, на нео-энеолитической керамике лесной полосы Восточной Европы. Большая часть таких изображений найдена на памятниках с ромбоямочной керамикой восточной части бассейна Балтийского моря. По мнению автора данной статьи, многие ямочные изображения являются схематичными или редуцированными фигурами водоплавающих птиц. Представленные данные позволяют предположить, что распространение гребенчатых плоскостных изображений птиц на ромбоямочной посуде обусловлено влиянием из области распространения типичной гребенчатой керамики. Отмеченные автором параллели в облике отдельных изображений птиц на ромбоямочной керамике и Онежских петроглифах могут быть использованы для датировки древних гравировок.

The article discusses spatial and stylistic features of the images formed by pits on the surfaces of Neolithic and Chalcolithic vessels from the forest zone of Eastern Europe. The most part of such images were found on the sites with Rhomb-Pit Ware in the Eastern Part of the Baltic Sea Basin. The article argues that significant part of the images formed by pits could be interpreted as the schematic or reduced figures of the waterfowl. Basing on the data published in the article, the author considers that the spreading of the waterfowl images formed by comb imprints on the Rhomb-Pit Ware vessels was conditioned by the influence from the zone of the typical Comb Ware. The article traces parallels between the figures of the waterfowl on the Rhomb-Pit Ware vessels and analogous figures of the petroglyphs of Lake Onega. These stylistic similarities could be used in dating of the rock carvings.

В статье представлены результаты изучения элементов погребального обряда населения Нижнего Приангарья в финале эпохи железа. Объектом исследования послужили костные кремированные останки и сопроводительный инвентарь могильника Пинчуга-6. На некрополе зафиксировано 16 погребений, выполненных по обряду трупосожжения на стороне. Всего было идентифицировано 30 индивидов разных возрастов. В ходе исследований выявлены одиночные детские и взрослые погребения, парные и коллективные комплексы. В последних захоронены костные останки трех или пяти человек. Среди находок из могильника отмечены предметы вооружения, орудия труда, керамические сосуды, предметы западносибирского культового литья, украшения. Отмечено наличие бронзовой торевтики только в погребениях, содержащих останки детей.

The paper presents results of the study aimed to examine elements of the funerary rite practiced by the Lower Angara population in the final stage of the Iron Age. Cremated bone remains and funerary offerings retrieved from the Pinchuga-6 cemetery were examined. The necropolis included 16 burials that contained bones selected for final burial from cremation on a pyre arranged aside. The number of identified individuals of different age totals 30. The excavations revealed burials of children and adults. The graves contained remains of one individual, as well as paired and multiple burials. In the latter bone remains of three or five individuals were identified. The finds from the cemetery included weapons, ceramic vessels, items of Western Siberia religious casting and pieces of jewelry. Bronze toreutics were recorded only in the burials with children's bones.
CREMATION IN THE FUNERARY RITE OF THE KUDASHEVSKIY I BURIAL GROUND (3rd-5th CENTURIES)
Authors: Казанцева О. А.
Published: November 2022

Впервые рассматриваются кремации Кудашевского I могильника эпохи Великого переселения народов в Среднем Прикамье. В погребальном обряде населения, оставившего курганно-грунтовый памятник, фиксируется ингумация. Аргументом для интерпретации таких могил является наличие жертвенного комплекса - элемента обряда финно-угров. Другой формой погребального обряда, выявленного на памятнике, является кремация, исследованию которой и посвящена статья. Применение методов наблюдения и статистического анализа кремаций позволяет отметить, что находки кремаций в виде кальцинированных костей и углей разнообразны по размеру, форме и концентрации; локализуются в погребениях, засыпи могил, предположительно в ритуальных ямах, между погребений на территории могильника. На памятнике фиксируется погребальная традиция с кремациями на стороне и отмечены ритуальные практики (поминальные тризны), в которых определенную роль играли животные. Смешение погребальных традиций - ингумации и кремации - связано с процессом взаимодействия местного и пришлого населения.

Cremations in the Kudashevskiy I cemetery in the Middle Kama region that dates to the Migration period are reviewed for the first time. In the funeral rite of the population that left behind the burial ground inhumation is recorded. The interpretation of such graves is supported by presence of a sacrifice complex, which is a ritual element of Finno-Ugric population. Another form of the funerary rite practiced by the population that buried their dead at this site and which is described in the paper is cremation. Based on the observation method and statistical analysis, a number of issues can be highlighted. The remains of cremations in the form of calcined bones and charcoal are diverse in size, shape and concentration; they are localized in the graves, grave infills, ritual pits, and between the graves in the cemetery. The archaeological site records a funerary rite with cremations on a pyre arranged aside and marks ritual practices (funeral feasts) in which animals played certain role. The mingling of burial traditions: inhumation and cremation is associated with interaction between the local and alien populations.
ASSESSMENT OF THE PREFERRED SELECTION OF CREMATED HUMAN REMAINS: ANALYSIS IN THE CONDITIONS OF UNCERTAINTY
Authors: Широбоков И. Г.
Published: November 2022

Как правило, только часть кремированных останков удается идентифицировать, а общая масса фрагментов и отдельных элементов скелета отличается высокой вариабельностью и почти всегда уступает ожидаемой по результатам наблюдений в крематориях. Целью настоящего исследования является разработка метода для оценки вероятности избирательного подхода к сбору останков для захоронения на стороне. Поскольку исходная масса конкретных трупосожжений неизвестна, фрагменты костей имеют разные размеры и продолжают разрушаться, а число элементов в генеральной совокупности и в выборке не может быть строго определено, точная оценка такой вероятности невозможна. Тем не менее расчеты можно попытаться провести для некоторого заданного диапазона величин. Наиболее надежные результаты позволяет получить анализ костей черепа, ожидаемая доля идентифицированных фрагментов которых относительно общей массы скелета сравнительно велика (13-20 %), а мелкие фрагменты относительно легко поддаются идентификации. Предложена схема для приблизительной оценки случайной вариации доли костей черепа при разном размере выборки, основанная на формуле гипергеометрической вероятности.

As a rule, when examining cremations, only some remains can be identified whereas the total weight of fragments and specific parts of the skeleton has high variability and almost in all cases is less than would be expected based on observations in crematoria. This study is aimed to develop a method for assessing probability of the selective approach to collection of cremated remains for subsequent burial in a grave. Since initial weight of specific cremated bodies is unknown, bone fragments are of different size, and the bones continue to disintegrate while the number of elements in the general population and the sample cannot be strictly determined, accurate estimation of probability is not possible. Still, we can attempt to make calculations for a certain preset range of values. The most reliable results can be obtained through analysis of skull bones since their expected share of identified fragments against the total weight of the skeleton is relatively high (13-20 %) and smaller fragments can be rather easily identified. The paper offers a model for rough estimation of random variation in the share of skull bones for the samples of different size based on the hypogeometric probability formula.
BONE AND ANTLER ANTHROPOMORPHIC FIGURES DATING TO THE STONE AGE FROM THE TERRITORY OF ESTONIA -DIFFERENT STYLES, DIFFERENT INTERPRETATIONS?
Authors: Йонукс Т. Х.
Published: November 2022

В статье дается обзор антропоморфных фигурок, найденных на территории Эстонии. Фигурки можно разделить на две категории: единичная антропоморфная скульптура, найденная в реке Пярну, и 11 небольших подвесок из роговых пластинок, обнаруженных на могильнике-поселении Тамула I. Помимо морфологических и хронологических различий, очевидно, существуют также различия семантического характера. В заключении говорится о том, что фигуркам охотников-собирателей эпохи каменного века не стоило бы приписывать одно-единственное исчерпывающее значение. Скорее, искусство эпохи каменного века отображает ряд различных значений даже в пределах одной и той же хозяйственной системы.

The paper provides an overview of anthropomorphic figures found in Estonia. Such figures can be divided into two categories: a singular anthropomorphic sculpture found in the Parnu river and 11 small pendants made from antler plates discovered at Tamula I which is a settlement and a burial ground. Besides morphological and chronological differences, some differences are, apparently, of semantic nature. The final part of the paper emphasizes that the interpretation of the figures made by Stone Age hunter-gatherers should not be considered exhaustive. Most likely, the art of the Stone Age reflects different meanings even within the same economic system.

Labor and employment sphere in the conditions of the digital economy: development prospects
Authors: Kirillova A. D. , Popov A. V.
Published: November 2022

The article provides an analysis of the digital transformation consequences for the development of the field of labor and employment. Particular attention is paid to the issues of job replacement, employment de-standardisation and structural shifts in the labor market as a whole. The information base of the research is made up of Russian and foreign literature, analyzed using general scientific methods. The results of the analysis confirmed the profound nature of the changes taking place which must be considered as an objective process of forming a new paradigm of the labor market with its advantages and disadvantages. This is most characteristically manifested in the widespread use of non-standard employment forms (platform, remote, etc.) which, among other things, carry a lot of risks for the younger generation. In turn, the threats of large-scale technological unemployment are seen as somewhat exaggerated, as evidenced by research, while the problem of polarization of the labor market is much more real. Summing up, authors have concluded that there is a need to improve public policy in the field of labor and employment to overcome challenges of the digital age.
Models of civil servants’ digital competence: approaches to formation and evaluation
Authors: Gegedyush N. S. , Maslennikova E. V. , Osipov V. A.
Published: November 2022

The purpose of the study is to analyze the Russian practice of assessing the digital competence of civil servants and substantiate proposals for improving approaches to assessing and developing the competencies under study. The article presents an analysis of the existing requirements for the competence of Russian civil servants, officially fixed and the compliance of such requirements with the current and promising areas of activity of state bodies and the development of modern society in the context of digital transformation. The authors studied approaches to the formation and application of civil servants’ digital competence models, including on the basis of the job regulations content analysis. In the course of the study, the authors conclude that there is sufficient uniformity of approaches in the executive authorities regarding the content of qualification requirements, which is predetermined by the implementation of the methodological tools of the Ministry of Labor and Social Protection of the Russian Federation. But professional knowledge and skills in the field of information and communication technologies, in fact, duplicate the basic qualification requirements and do not reflect the use of information and communication technologies specifics in various industries and the differentiation of employees’ functionality depending on categories and groups of positions. The authors substantiate proposals regarding the formation of a model of digital competence, namely, the need to take into account the division of requirements into basic and professional ones, the reflection of differentiation into categories and groups of civil service positions.

Today’s society faces many challenges, including those related to quality of life, level of health and living conditions in general. Now in the world there is a tendency to develop equal conditions for all people, including people with disabilities. This issue is relevant in many countries, in particular in Russia every year measures are taken to create more and more comfortable living conditions for people with disabilities. And the purpose of the article is to investigate trends in improving living conditions for people with disabilities, in particular based on historical experience and the current state of affairs. Methods of content analysis, observation and a systematic approach were used in the study. As a result, the experience of various countries in creating conditions for people with disabilities was reviewed, statistical data was given, and the current state in Russia was examined. The following trends were revealed: the disability support system is developing annually, but there are still many problems at the stage of implementation and realization in practice. There is an insufficiently developed set of measures for the creation of a supportive environment. The geography of development is not wide enough; the assistance that people with disabilities receive in large centers is not available to the population from remote areas, small settlements. Nevertheless, there are many social support programs, assistance with habilitation and rehabilitation, and measures to equip public access facilities for the convenience of people with limited mobility.

Published: November 2022

The problem of interdisciplinary educational integration reflects the realities of the modern world. Rapidly changing technologies set new requirements for the training of specialists capable of innovation. The study of the vertical and horizontal interdisciplinary integration resources for the disciplines of the humanities and management cycle is the purpose of this work. The structure of the article includes a theoretical and methodological analysis and an empirical part, represented by two stages of research (for socio-humanitarian and management disciplines). The article presents the results of modern views on the problem of interdisciplinary integration in higher education. The results of the theoretical analysis showed a mismatch between the depth of the theoretical study of the problem and the success of their practical implementation in the conditions of modern higher professional education. The complexity of the implementation is due to the changed psychological and socio-psychological characteristics of Generation Z students. Based on the theoretical analysis, a typology of interdisciplinary competencies was proposed. The aim of the empirical part of the study was to study the resources of vertical and horizontal integration at a technical university. Based on the empirical research, the possibilities of vertical and horizontal integration of the disciplines of the socio-humanitarian and management cycle were identified. An integrative matrix is presented. A promising direction for this topic is the development of an integrative module “Management workshop”.

Published: November 2022

The principles of ESG in management as the basis of sustainable development of the company, industry and economy in general are considered in the article. The authors deal with the issue, whether the rupture of economic links and financial schemes, as well as the exception of the Russian companies from the international ESG-ratings can lead to refusal of the ESG-principles in management. The features, peculiar to each of the ESG aspects in the conditions of the anti-Russian sanctions in 2022 are considered. The problems and strengths of the Russian companies, the degree of prevalence of the ESG principles among the Russian entrepreneurs are revealed. According to the data of analyst companies, research and polls, the authors conclude, that the enterprises applying the ESG-principles have more chances to recover from the current crisis successfully.
Neural Network Based ∆-Machine learning approach efficiently brings the DFT potential energy surface to the CCSD(T) quality: a case for the OH + CH3OH reaction
Authors: Song Kaisheng , Li Jun
Published: November 2022

The recently proposed permutationally invariant polynomial-neural network (PIP-NN) based ∆-machine learning (∆-ML) approach (PIP-NN ∆-ML, J. Phys. Chem. Lett. 2022, 13, 4729) is a flexible, general, and highly cost-efficient method to develop full dimensional accurate potential energy surface (PES). Only a small portion of points, which can be actively selected from the low-level (often DFT) points, with high-level energies are needed to bring a low-level PES to a high-level of quality. The hydrogen abstraction reaction between methanol and hydroxyl radical, OH + CH3OH, has been studied by theories and experiments for a long time due to its great importance in combustion, atmospheric and interstellar chemistry. However, it is not trivial to develop the full dimensional accurate PES for it. In this work, the PIP-NN ∆-ML method is successfully applied to the title reaction. The DFT PES was fitted by using 140192 points. Only 5% of the DFT dataset was needed to be calculated at the level of UCCSD(T)-F12a/AVTZ, and to improve the DFT PES to the target high-level, UCCSD(T)-F12a/AVTZ. More than 92% of the original unaffordable calculation cost were saved. The kinetics, including rate coefficients and branching ratios, were then studied by performing quasi-classical trajectory calculations on this newly fitted PES for the title reaction.

Published: November 2022

Ca2+ ions play crucial roles in regulating many chemical and biological processes, but its impact on lipid bilayer membranes remains elusive, especially when the impacts on the two leaflets are asymmetrical. Using a recently developed multisite Ca2+ model, we performed molecular dynamics simulations to study the impact of Ca2+ on the properties of membranes composed of POPC and POPS, and observed that both the structure and fluidity of the membranes were significantly affected. Particularly, we examined the influence of asymmetrically distributed Ca2+ on asymmetric lipid bilayers, and found that imbalanced stress in the two leaflets were generated, with the negatively charged leaflet on the Ca2+ rich side becoming more condensed, which in turn induced membrane curvature that bent the membrane away from the Ca2+ rich side. We employed continuum mechanics to study the large-scale deformations of the membrane and found that membranes can develop into locally pearl-shaped or globally oblate, depending on the specific Ca2+ distributions. These results provide new insights to the underlying mechanism of many biological phenomena involving Ca2+-membrane interactions, and may lead to new methods for manipulating membrane curvature of vesicles in biological, chemical, and nano systems.

The development and characterization of active and selective catalysts is critical for the simulation and optimization of electrochemical synthesis of chemicals and fuels using renewable energy. The rate of electrochemical generation of a specific product as a function of electrode potential can be described by a Tafel equation, which depends on two parameters: the Tafel slope (or the related transfer coefficient) and the exchange current density. However, common methods for calculating Tafel slopes are subjective and limited by data insufficiency resulting from challenges associated with product quantification, and, as shown here, the effects of mass transport, bulk reaction occurring in the mass-transfer boundary layer, and the occurrence of competitive surface reactions. Errors in the Tafel slope extracted from experimental data can also lead to errors in the exchange current density estimation. To address these issues, we present a technique that leverages statistical learning methods informed by physics-based modeling to calculate kinetic parameters (the transfer coefficient and exchange current density) with quantified uncertainty. The method is applied to 21 sets of data for the electrochemical reduction of CO2 to CO and H2 on Ag catalysts acquired under similar experimental conditions. We find that fitted values for the transfer coefficient and exchange current density do not converge to a unique set of values, and that there is an apparent correlation of these parameters; however, the most probable value of the exchange coefficient for CO and H2 formation correspond reasonably well with the DFT-predicted values of this parameter. While the system explored is relatively simple, the techniques developed can be used to evaluate the transfer coefficient and exchange current density for many other electrochemical processes.

Published: November 2022

A photosensitive and transition metal-free technique without inert gas shielding is reported for the facile synthesis of multifunctional coumarins. The current proce-dure avoids the inherent drawbacks of the previous coumarin production protocol in the presence of transition metal. The prominent aspects of the methodology also include the absence of photocatalyst, the absence of external additives including transition metals, and the employment of a straightforward precursor. Additionally, we went into great detail on the mechanistic investigation and utilization of multi-functional coumarins.

Published: November 2022

Magnetically active atomic distances may impact the magnetic ordering in a given system both directly and indirectly. We synthesize three novel quasi one-dimensional organic-inorganic hybrid cobalt chloride chain compounds (CH3NH3CoCl3, CH(NH2)2CoCl3, and C(NH2)3CoCl3) and characterize their magnetic and thermodynamic properties. These materials crystallize in a hexagonal perovskite-type structure consisting of chains of face-sharing Co-Cl octahedra separated by the respective organic cation. Temperature and field-dependent magnetic susceptibility analyses reveal that each compound possesses antiferromagnetic intrachain coupling, and that the strength of the correlations is comparable across the three materials. Moreover, the interchain Co-Co distance, which depends on the size of the organic cation, is directly related to the temperature at which long-range magnetic ordering occurs.
Sparsity of the Electron Repulsion Integral Tensor Using Different Localized Virtual Orbital Representations in Local Second Order Møller-Plesset Theory
Authors: Wang Zhenling , Aldossary Abdulrahman , Head-Gordon Martin
Published: November 2022

Utilizing localized orbitals, local correlation theory can reduce the unphysically high system-size scaling of post-Hartree-Fock (post-HF) methods all the way to linear scaling in insulating molecules. Revealing the numerical sparsity of the 4-index electron repulsion (ERI) tensor is central to achieving linear scaling in local correlation methods. For second order Møller-Plesset theory (MP2), one of the simplest post-HF methods, only the $(ia|jb)$ ERIs are needed, coupling occupied orbitals $i,j$, and virtuals $a,b$. In this paper, we compare the numerical sparsity (called the "ragged list representation") and the low-rank sparsity of the $(ia|jb)$ ERI tensor. The ragged list requires only one set of (localized) virtual orbitals, and we find that the orthogonal valence virtual-hard virtual (VV-HV) set of virtuals originally proposed by Subotnik et al. gives the sparsest ERI tensor relative to 4 other good choices: projected atomic orbitals (PAOs), Boys localized virtuals, Pipek-Mezey localized virtuals, and Cholesky localized virtuals. To further compress the $(ia|jb)$ ERI tensor, the low-rank (pair-natural orbital) representation uses different sets of virtual orbitals for different occupied orbital pairs. Our results indicate that while the low-rank representation achieves significant rank reduction, it also requires more memory than the ragged list representation. An approximation (called the "fixed sparsity pattern") for solving the local MP2 equations using the numerically sparse ERI tensor is proposed and tested to be sufficiently accurate and to have highly controllable error. A low-scaling local MP2 algorithm based on the ragged list and the fixed sparsity pattern using this representation is therefore promising.
