Sentiment analysis of Indonesian government policy in the era of social commerce: public perception and reaction
Authors: Sugiarti Sugiarti , Arsi Primandani , Subarkah Pungkas , V Jay
Published: December 2024

This research explores public sentiment towards the Indonesian government’s policies in the era of social commerce, based on Minister of Trade Regulation No. 31 of 2023. Sentiment analysis was conducted on a dataset comprising 1013 tweets on Twitter, employing various machine learning algorithms, including Naïve Bayes, Logistic Regression, Random Forest, SVM, and KNN. The results reveal that the Support Vector Machine (SVM) algorithm achieved the highest accuracy rate of 87%, outperforming other algorithms. Analyzing public sentiment towards the mentioned government policies, positive sentiment accounted for 20.2%, while negative sentiment reached 79.8%. This suggests that the policies, as outlined in the regulation, did not elicit a positive response from the public. Recommendations for future research include expanding the dataset and incorporating diverse data sources beyond Twitter for enhanced accuracy. This study contributes valuable insights into public sentiment analysis, particularly in the context of social commerce policies, providing a foundation for further investigations and policy adjustments.

Published: December 2024

This study aims to analyze public sentiments towards Rohingya refugees in Indonesia using the IndoBERT model. We collected sentiment data from social media platforms and news articles, followed by preprocessing techniques including tokenization, cleaning, case folding, stemming, and filtering. Sentiment labels were assigned using the InSet lexicon, and the IndoBERT model was trained with these labeled data. Our findings reveal that the predominant sentiment is negative, with 65% of the sentiments classified as negative, 20% as neutral, and 15% as positive. The model demonstrated robust performance with an accuracy of 87%, precision of 85%, recall of 83%, and an F1 score of 84%. This research addresses a gap in sentiment analysis studies related to refugee issues and provides valuable insights into public perceptions, which could inform policies and interventions aimed at improving refugee integration and support systems in Indonesia.
Comparison of K-Nearest Neighbor and Naïve Bayes algorithms for hoax classification in Indonesian health news
Authors: Pratomo Awang Hendrianto , Rachmad Faiz , Kodong Frans Richard
Published: December 2024

The categorization of health-related hoaxes is paramount in determining if they report facts. This paper analyzes the accuracy of the K-Nearest Neighbor (KNN) and the Naïve Bayes Classifier as two algorithms for health news hoaxes classification. Text mining was employed by feature extraction employing the TF-IDF method from the news headlines to classify the clusters. A prototype model was used to develop the system. Models assessment included confusion matrices and k-fold cross-validation. K=3 KNN model attained an average accuracy of 82.91%, precision of 85.3% and recall of 79.38% with no predictors included. The best performance was recorded for using the Naive Bayes model at fixation of K=3 KNN model at an average accuracy of 86.42%, precision level of 88.10% and recall high of 84.05%. These findings suggest that the KNN surfaces in the last model level rather than in the absence of the Naive Bayes model concerning classifying the hoax position of health news visible through the confusion evaluative matrix. Although related studies have been conducted in the past, this study is dissimilar in terms of its preprocessing methods, size of the data, and outcomes. The dataset consists of 1219 hoaxes labelled and 1227 facts labelled news headlines

Agroforestry in arid areas for reducing the impact of drought and soil degradation on agricultural production
Authors: A. Korneeva E.
Published: December 2024

Agricultural production in arid areas struggles to meet modern environmental management challenges. Unsustainable practices under drought conditions have led to soil fertility loss, structural damage, erosion, and deflation, negatively affecting crop yields. The solution lies in adopting resource-efficient, nature-based technologies. Agroforestry systems effectively combat drought and land degradation in arid regions, mitigating these issues and enhancing agricultural productivity. To identify the role of protective forest plantations in the economy of agricultural production, an assessment was carried out on the gross wheat harvest and net income from its sale with minor and active wind activity under various agroforestry strategies. A comparison of various options for afforestation of fields in the steppe zone of the Volgograd region (Russia) showed that the greater the protection of fields due to the convergence of distances between protective plantations, the higher the efficiency of agroforestry. The cost of mitigating the effects of drought and soil degradation in agroforestry systems with low intensity is USD 12- USD 25 per 1 ha of forested land use. With an increase in the intensity of degradation to the level of a dust storm, the cost of mitigating its consequences is USD 171-USD 280. This indicates the great relevance and economic feasibility of forest reclamation measures in the region.

The process of rearrangement of the octadecahydroeicosaborate anion [trans-B20H18]2– → [iso-B20H18]2– in various solvents (acetonitrile, DMF, DMSO) under UV irradiation in dynamics has been studied using 11B NMR spectroscopy. It has been shown that the time of complete isomeric transition depends on the solvent used. In acetonitrile, complete conversion of the [trans-B20H18]2– anion to the iso form is achieved in 1 h; in DMF, the process takes about 2 h; in DMSO, about 3 h. The reverse process of rearrangement of the macropolyhedral borohydride anion [iso-B20H18]2– → [trans-B20H18]2– has been studied under the influence of temperature in DMF and it has been shown that an increase in the reaction time and an increase in the temperature of the reaction solution is accompanied by degradation of the boron cluster.

Synthesis conditions were developed, new compounds of compositions (HOOC(CH2)5NH3)2SiF6 (1) and [Cu(Cpl)2(H2O)2SiF6]·2Cpl (2), where (Cpl – ɛ-caprolactam, ɛ-C6H11NO, (HOOC(CH2)5NH3)+ – cation 5-carboxypentylammonium) were obtained from aqueous solutions and studied by chemical, IR spectroscopic and X-ray diffraction analyses. In the structure of compound 1, the coordination environment of the Si atom is an almost regular octahedron. Crystals are triclinic sistem, space group P1¯. During crystallization, caprolactam undergoes a hydration reaction and protonation. In structure 1, hydrogen bonds F...H–N were found between anions and organic cations, as well as “acidic” hydrogen bonds between carboxyl groups of cations. Compound 2 crystallizes in the triclinic system, space group P1¯ and has a polymer chain structure. The coordination polyhedron of two independent copper cations is a tetragonally distorted octahedron formed by the O atoms of two Cpl molecules and two F atoms of hexafluorosilicate anions acting as bridges between neighboring cations. The coordination environment of the Si atom is a slightly distorted octahedron. The structure contains hydrogen bonds between the H atoms of coordinated water molecules and the O atoms of uncoordinated Cpl molecules. The geometry of hexafluorosilicate anions in structures 1 and 2 is identical.

Published: December 2024

Within the framework of the cluster approach using the 6‒31G* basis set and the hybrid density functional (B3LYP), we modeled successive abstraction of H2 from the complexes (Mg(BH4)2∙2NH3)2 and (Mg(BH4)2∙2NH3)4. It was found that the initial stage of dehydrogenation needs overcoming energy barriers ~ 1.5‒1.2 eV, which requires preheating, then the process can go on with energy release until about 10 wt % of H2 is extracted, for a higher degree of conversion, additional energy costs exceeding the combustion heat of H2 will be required when extracting more than 12.5 wt % of H2. Therefore, further dehydrogenation of this compound may turn out to be inexpedient from the energy point of view.

Published: December 2024

The heat capacity of LaMgAl11O19 with a magnetoplumbite structure was measured in the temperature range of 7–1865 K using relaxation, adiabatic and differential scanning calorimetries. Obtained temperature dependences of the heat capacity are consistent based on adiabatic calorimetry data. Thermodynamic functions (entropy, enthalpy change, reduced Gibbs energy) in the range 0–1865 K are calculated from fitted values. Thermal expansion in the range of 300-1200 K was studied by high-temperature X-ray diffraction and the coefficient of thermal expansion of LaMgAl11O19 was calculated.

The application of zinc oxide ZnO nanorods of different heights obtained by hydrothermal synthesis as functional layers for dye-sensitized solar cells has been considered. The structure, morphology, and optical properties of the nanorod layers were investigated by X-ray phase analysis, scanning electron microscopy, and optical spectroscopy. Photoanodes were fabricated using thieno[3,2-b]indole-based dyes IS 4 and IS 9. The adsorption mechanism of the dyes and ZnO structures was studied by IR spectroscopy. The efficiency of photoanodes was investigated using photoelectrochemical measurements. The dependence of the efficiency of the dye sensitized solar cells on the length of the nanorods was shown. The maximum light conversion result was obtained for a photoanode with an average nanorod height of 2.5 μm and dye adsorbed IS 4.

Published: December 2024

We fabricated and studied composites made of titania (TiO2), zinc oxide (ZnO) or graphitic carbon nitride (g-C3N4) nanoparticles (20–100 nm) in polymethylmethacrylate (PMMA). Nanodispersed powders of these semiconductors were mixed with mechanically grinded PMMA at a weight ratio ranging from 1 : 5 to 1 : 20. The mixture was dissolved in acetone and deposited on to the surface of water. Upon solidification and drying in air porous discs as thick as 50–200 μm were formed. They were found to have a mechanical durability at the semiconductor to PMMA ratio above 1 : 20. Scanning electron microscopy, energy dispersive x-ray spectroscopy, x-ray difractomenry of the samples demonstrated that semiconducting nanoparticles are quasiuniformly distributed in the polymer matrix. Their crystal structure, the particle size and the composition do not change in comparison to those before synthesis of the composites. Photocatalytic activity of the synthesized composites estimated by decolarization of water solution of the test dye (methylene blue) under UV irradiation was found to be reduced in the sequence TiO2, g-C3N4, ZnO.
Helminth fauna of auks (Charadriiformes, Alcidae) in the Barents Sea: composition, structure, ways of formation
Authors: Kuklin V. V. , Kuklina M. M. , Ezhov A. V.
Published: December 2024

Based both on original and literary data, the results of long-term studies on the helminth fauna of alcids (the Little Auk, Alle alle, the Razorbill, Alca torda, the Atlantic Puffin, Fratercula arctica, the Black Guillemot, Cepphus grylle, the Common Guillemot, Uria aalge, and Brünnich’s Guillemot, U. lomvia, in the Barents Sea region are summarized. 31 species of helminthes (4 trematodes, 11 cestodes, 12 nematodes and 4 acanthocephalans) have been revealed. Some of them circulate in coastal ecosystems, but the realization of life cycles in most species occurs in the pelagial zone with the participation of planktonic invertebrates and fish as intermediate and transport hosts. 24 helminth species of 31 do not reach sexual maturity in alcids and use either other birds or marine mammals as obligate definitive hosts. The structure of the parasitic fauna and the peculiarities of geographic and interspecific distribution of helminthes are related to the evolutionary age of parasite-host systems, host ecology and parasite specificity. A comparative analysis of the helminth faunal composition of alcids in the North Atlantic and Barents Sea shows that Barents Sea birds have a lower diversity of trematodes and cestodes. Differences in the nematode faunal composition are insignificant, whereas records of acanthocephalans are more frequent in the Barents Sea. This seems to be accounted for by different species of parasites having different requirements for environmental conditions and varying degrees of specificity to both intermediate and definitive hosts.

The Pancreas Aselli, central fatty inclusion or large mesenteric lymph node of shrews (Soricidae, Eulipotyphla)
Authors: Davydova Yu. A. , Nesterkova D. V. , Drozdova L. I.
Published: December 2024

Pancreas Aselli, large mesenteric gland, central fatty inclusion, fatty or large lymphoid body are some of the names for the large mesenteric lymph node characteristic of shrews. Despite the attention this organ has attracted due to its large size comparable to that of a kidney, it has long remained a mystery to theriologists. Due to the seasonal and age-related variability in weight and size revealed, it has been allotted exclusively metabolic or even storage functions. An analysis of the studies on the large mesenteric lymph node has made it possible to trace the changing views on the roles this organ play in the lymphatic and immune systems of shrews, and to assess the prospects for its further study.

Published: December 2024

The movements of three mature beluga whales (Delphinapterus leucas) tagged by satellite transmitters off the western coast of Kamchatka Peninsula were analyzed. Before the formation of ice cover, beluga whales remained off the western coast of Kamchatka and in the Shelikhov Bay. As ice was formed and spread, beluga whales used increasingly deeper water areas. The data obtained indicate the possible residence of belugas in the eastern part of the Sea of Okhotsk and prove the genetic isolation of this beluga population from that of the western Sea of Okhotsk.

Authors: Belkina Galina L. , Korsakov Sergey N. , Frolova Maria I.
Published: December 2024

In the article dedicated to the anniversary of the outstanding Russian philosopher Academician Ivan Timofeevich Frolov, an attempt is made to give a general assessment of his work from the perspective of today. His main scientific achievements are briefly listed. Emphasis is placed on the area of his philosophical studies that is increasingly coming to the fore as the most relevant: the future of man and new technologies. A general description of I.T. Frolov’s approach to the problem of human interaction with new technologies, especially biotechnologies is given. It talks about I.T. Frolov’s criticism of neo-eugenics, which was essentially directed against the transhumanism that arose in the last decade of his life. He considered any manipulation of human genetic nature, which is motivated by commercial or political considerations, dangerous to the survival of humanity. It is noted that I.T. Frolov considered it possible to proceed to the creation of organisms with a programmed set of genetic characteristics only if such conditions as achieving social homogeneity of society and the progress of the scientific study of human biology are met. The evolution of philosophical and socio-political views of I.T. Frolov is traced, the main stages of their development are identified. Characteristics are given of the concept of humane democratic socialism, which I.T. Frolov always adhered to. In conclusion, it talks about the ideas associated with the conditions and prospects for the revival of Russia to which I.T. Frolov came in the last years of his life. Among such ideas, he included historical reconciliation, which would allow the best of all stages of the country’s development to be included in the national identity, and a focus on the priority of man in all aspects of the life of Russian society.
Man and color: the coloristics of the cultural landscape
Authors: Griber Yu. А.
Published: December 2024

The article presents an overview of modern theories and methodological approaches that expand the usual research practice of studying the colorism of cultural landscapes, offering special tools capable of recording how people actually see color in a cultural landscape, what they feel, how they remember and use it. Cultural landscapes, among which modern man spends most of his life, combine natural and anthropogenic layers, representing a special system of cultural matrices and codes directly linked to a particular territory. Regardless of type, size and structure, each cultural landscape has a characteristic color. The study offers an analysis of a number of ideas important for comprehending (1) the spatial imagery of cultural landscape colorism, (2) the mechanisms of perception and (3) the construction of its constituent color images. Particular attention is paid to the analysis of the multimodal nature of the color image, its mobility and holism of perception. The methodological significance of geographical determinism theories for understanding the mechanism of colorism formation in the cultural landscape is discussed. The analysis presented in the article allows us to better understand the nature, highlight the key features of cultural landscape colorism and determine its significance for human beings. The shift of emphasis from the study of the relationship between color and objects to the relationship between color and man sets a special vector of research: not “from above”, but “from within”, “at close range”, from the position of an observer immersed in the color environment. Such a change in optics, along with theoretical aspects, is important for applied projection into various target spheres of the cultural landscape. In particular, for the formation of color environment corresponding to the expectations and demands of various social groups of modern society.
On the human-dimensionality of culture (a sketch of theory)
Authors: Kramer Alexander Yu.
Published: December 2024

The article is a sketch of a theoretical approach (or, more precisely, a research program) to human culture, which is based on the human-dimensionality, given as a set of irremovable natural limitations that man, as a natural being, imposes on everything thought, felt, made, changed, stored and used by him. Culture is presented as a multidimensional net/meshwork of cultural objects understood as an assemblages/re-assemblages that involve human-dimensional and non-human-dimensional artifacts, non-human actants, and humans as a condition and carriers of practices Humans act as mobile nodes of net/meshworks, moving along certain trajectories of their everyday habitat, the “enculturation” of that habitat is determined by the configurations of “awaiting” artifacts and “waylaying” non-human actants on their paths. A human, moving along his trajectories, assembles practices with artifacts of the environment, forming cultural objects; by the latter, as well as by the cultural objects one carries, a human can link with the cultural objects of other humans on the same or intersecting routes. Thus, couplings and multi-couplings of cultural objects are formed, which recreate a complex and constantly reassembling multidimensional net/meshwork. Configurations of relatively reproducible couplings in the net/meshwork we call retentions, the presence of which determines the state of culture; in the case of the coercion of retentions to be reproduced, we speak of a state of civilization. The first part of the article sets out the conceptual logic of the approach; the second part (which is an essay) provides a sketch of the analytical optics possible with this approach.
“A man of ‘fire and flame’”. on the 250th anniversary of D.M. Vellansky
Authors: Shchedrina Irina O. , Shchedrina Tatiana G.
Published: December 2024

Today, we return to the history of Russian philosophy not so much to once again emphasize its dependence on European methodological frameworks, but rather to comprehend its cognitive value and positively evaluate its contribution to the development of Russia’s intellectual culture, the Russian philosophical language, and Russian speech. In December 2024, the philosophical and scientific communities will celebrate the anniversary of the natural philosopher, scholar, and Doctor of Medicine and Surgery, Daniil Mikhailovich Vellansky, whose original works and translations influenced the development of 19th-century Russian philosophy and science. Vellansky’s passionate methodological call for the theorization and philosophical systematization of medical knowledge was notably different from the practice-focused Russian medicine of his time, which sought to understand the human organism through “experimental” approaches. Although Vellansky’s natural philosophical reflections — drawing from but not merely replicating Schelling — were criticized among medical scientists, his philosopher colleagues, such as Moscow University professors I.I. Davydov and M.G. Pavlov, showed genuine interest in his attempts to apply Schelling’s teachings to “physical subjects.” By placing the intellectual legacy of D.M. Vellansky in the broader context of contemporary issues in philosophy and the methodology of science, particularly in the epistemology of medicine, we gain a fresh perspective on his idea of the “wholeness of Man”, which he established as the foundation of medicine as an science. This thought of Vellansky’s is particularly relevant today in the context of modern interdisciplinary research programs (for example, the ecologization of medical practice), which take into account the human-sized character of scientific knowledge.
In search of yeti (a response to Sergei Nikolsky’s book “The Soviet. literary and Philosophical Analysis”)
Authors: Leibovich Oleg L. , Kazankov Aleksandr I.
Published: December 2024

The response article to the book by S.A. Nikolsky “Soviet Philosophical and Literary Analysis” is a dialogue between Oleg Leibovich and Alexander Kazankov. The conversation covers a wide range of topics related to reading the specified treatise. Firstly, the possibility of classifying S.A. Nikolsky’s philosophical analysis as a real anthropological type is discussed. According to modern Russian sociologists, the Soviet man emerged in the 1960s and his presence in society can be confirmed by mass surveys. However, this scientific approach is not interesting for S.A. Nikolsky, as both interlocutors point out. For a philosopher, it is not a question of whether or not the Soviet person existed, but rather who he was and what his role in literature was. Even if you assign it the status of a noumenal thing-in-itself or a hypothetical Bigfoot, it is a legitimate subject for literary and philosophical analysis. S.A. Nikolsky’s methodology allowed him to identify two fundamental features in the image of the Soviet man: clandestine and submissive. According to the author, these human qualities were discovered by Russian literary classics (I.S. Turgenev, F.M. Dostoevsky, N.S. Leskov, etc.). During the discussion, it turns out that the existence of substantial human qualities is problematic, and clandestinity and submission are socially conditioned features of the ethos of the Russian writing intelligentsia itself. The interlocutors conclude their discussion of S.A. Nikolsky’s treatise on Soviet man with a discussion on the actual “Sovietness” of Soviet man.

QUANTITATIVE CONTROLLABILITY INDEXES OF NONLINEAR SYSTEMS
Authors: Pirogova A. D , Chetverikov V. N
Published: December 2024

The problem of optimal choice of system parameters with respect to a given control quality criterion is studied. To compare systems with different parameter values, a quantitative estimation of controllability is introduced. This estimation is based on the average value of the function that defines the quality criterion. As an example, a very simplified model of an underwater vehicle is considered. The problem of finding an arrangement of its control propellers, in which either the movement time or the energy consumption of the vehicle is minimal is investigated. To test the used approach, the trajectories of the underwater vehicle are randomly generated. The energy consumption and the movement time along these trajectories of systems with different parameter values and different indexes are compared.

We consider the case when the Hamiltonian system has dimension 8 and is a small (in the sense of the action of the Fuller group) perturbation of the Hamiltonian system of the generalized Fuller problem with control in a disk. For this class of problems we prove the existence of extremals in the form of logarithmic spirals, which reach the singular second-order extremal in a finite time, while the control performs an infinite number of rotations around the circle.
