Che vuoi? (The Choice of the Faculty of Philosophy (MSU) and the Attempt of the “Logos” of the 1990s)
Authors: Nikiforov O.V.
Published: November 2023

The text thematizes the “subcultural-philosophical” situation of the 1990s in “post-Soviet” Russia highlighting the context of “relevance” and “fragmented discontinuity” of the period when personal “philosophical choice” was coupled with the urgency of practical actions for the formation of micro-communities (one of the longest and most notable at that time was the philosophical journal Logos (Moscow, 1991...)) that studied the array of both domestic and world “philosophical heritage” in terms of their discovery for self-actualizing thought-action of those who participated in that philosophical generation of the “vague” 1990s.
Ethnopolitical Conflicts in Transit Time as Moral and Psychological Phenomenon (Attempts of Diagnosis and Treatment)
Authors: Obolonsky A.V.
Published: November 2023

The article is devoted to an analytical review of psychoanalytic and other psychological approaches to the description and overcoming of ethnopolitical conflicts in Russia and other post-Soviet countries. The materials of the multinational research group International Dialogue Initiative and the scientific works of its members are widely used. The concept of psychological trauma is considered in detail, as well as the phenomenon of post-traumatic syndrome inherent in societies of the transit period. National enmity is considered on the basis of a number of examples through the prism of the psychoanalytic concept of “chosen” trauma. Considerable attention is paid to the psychological aspects of the treatment of ethnotrauma. In this regard, the positive aspect of the attitude to the past wars is considered as a common, but already experienced, mourned and buried trauma, which, from the point of view of psychoanalysis, contributes to its adaptive experience and transformation in the public consciousness, and, ultimately, reconciliation between former enemies. One of the key factors for this is the concept of the universal human need to have both enemies and allies developed by the outstanding psychoanalyst V. Volkan.
Towards a General Theory of the Crisis of the Empire
Authors: Buldakov V.P.
Published: November 2023

The author claims that the roots of the revolution lie deeper than allowed by the mentality of the Enlightenment. It should be considered in the paradigm of historical cyclicity, which produced especially large-scale and painfully affects to complexly organized imperial systems. As applied in Russia in the 17th – 20th centuries, the systemic crisis, with varying degrees of intensity, went through the following stages or levels: ethical, ideological, political, organizational, social, ochlocratic, recreational. It was a synergistic process, the chaotic course of which, in the final analysis, turns out to be dependent not on ideology and politics, but on the psychology of the masses. Its result was due to the fact that the masses, having exhausted all the possibilities of getting out of a critical situation, turned to historical experience, that they see. In Russia, it is associated mainly with the paternalistic type of worldview.
Cognition of the Alien as a Way of Self-Knowledge: The West, India, Russia (an Attempt at Xenology)
Authors: Lysenko V.G.
Published: November 2023

The article proposes a philosophical concept of “xenology” (the science of alien) as a way of knowing oneself through the knowledge of the culturally and civilizationally alien as a way of forming identity “self-construction”. The author formulates four principles of xenology. First: we can realize our Self only through the “not-Me”, the other, the alien. Second: civilizational, cultural and national identity is actualized when confronted or in conflict with someone else's identity. For example, the Greeks realized themselves as “political animals” only against the background of “barbarians”. Third: our “self-construction” is already embedded in the very model of someone else. Fourth: the image of a stranger in a particular culture can serve as an important indicator of its level of development (tell me what your alien is, and I'll tell you what you are), as well as an instrument of both self-affirmation and self-understanding, self-esteem, self-criticism, and a stimulus for self-improvement. As an illustration of these principles, the article offers nine models of the alien, highlighted on the material of the cultural history of two civilizations – European and Indian as well as in connection with the analysis of modern Russian reality. The models develop into a sequence that is determined by the movement from the biological to the social and cultural: xenophobic (ethological), mythological, model of antipodes, model of races, model of the initial state, passeist model, model of the natural state, heterotopic and universalist models. We humans, as a biological species, have a fear of the alien, but we rise above this fear with the help of social and cultural mechanisms that allow us to expand and deepen our identity from family, collective, ethnos, nation to the entire human race (presumption of humanity). In the conclusion of the article, the author examines the manipulation of “friend-foe” identities based on the xenophobic model in modern Russian political discourse.
Primerjava med študijami o varnosti v lokalnih skupnostih v letih 2011, 2017 in 2022 – perspektive prebivalcev in policistov
Authors: Meško Gorazd
Published: November 2023

V prispevku predstavljamo preliminarne ugotovitve analiz podatkov iz študij v 24 lokalnih skupnostih in na 24 policijskih postajah v Sloveniji (v letih 2011, 2017 in 2022). Eksplorativna faktorska analiza (EFA) za vzorec občanov (N = 3.372) pokaže faktorje o zaznavanju groženj varnosti v lokalnih okoljih, sodelovanju občanov pri zagotavljanju varnosti, prepričanjih glede nalog občine pri različnih dejavnostih, mnenjih o tujcih in migrantih, socialni povezanosti v lokalnem okolju in splošni oceni dela policije. EFA na vzorcu policistov (N = 1.554) ima nekoliko drugačno strukturo in se kaže v faktorjih o zaznavi virov ogrožanja varnosti, uspešnosti policije, sodelovanja občanov pri zagotavljanju varnosti, nalogah občine, socialni povezanosti in revščini. Trditve iz faktorjev smo primerjali z diskriminantno analizo. Primerjave so predstavljene po letih in razložene v kontekstu družbenih dogajanj v treh časovnih obdobjih.
Fizična in socialna (ne)urejenost bivalnega okolja v Sloveniji – longitudinalna perspektiva
Authors: Erčulj Vanja
Published: November 2023

Urejenost okolja je povezana s strahom pred kriminaliteto, ta pa s samozaščitnim vedenjem in izogibanjem določenim dejavnostim ter predelom soseske. S tem se zmanjša tudi neformalni nadzor v soseski ter poveča prisotnost deviantnega vedenja. Pri neurejenosti okolja je treba ločiti med fizično ter socialno neurejenostjo. V okviru raziskave o varnosti v lokalnih skupnostih se je nekaj vprašanj nanašalo tudi na obe vrsti (ne)urejenosti okolja. Raziskava je longitudinalna, saj je potekala v letih 2011, 2017 in 2022. V prispevku proučimo stopnjo vsake od omenjenih (ne)urejenosti okolja skozi čas ter primerjamo oceno neurejenosti okolja med prebivalci občine Kranj in prebivalci drugih občin. Čez leta je v Sloveniji prišlo do razlik v zaznavanju socialne neurejenosti, ne pa tudi fizične neurejenosti okolja. Zaznavanje fizične neurejenosti okolja v občini Kranj se je čez leta gibala drugače kot v preostali Sloveniji.
Posebnosti naročanja detektivskih storitev v lokalnih skupnostih – analiza primera slovenske občine
Authors: Dvojmoč Miha
Published: November 2023

Zagotavljanje varnosti v lokalni skupnosti je treba razumeti v širšem pomenu, saj presega delovanje zgolj ene ali dveh služb. S pluralizacijo policijske dejavnosti se tako na lokalni ravni aktivneje vključujejo tudi detektivi, saj področna zakonodaja izvajanja detektivskih storitev lokacijsko ne omejuje. Naročanje detektivskih storitev za lokalne skupnosti je pomembno pri reševanju različnih problemov, kot sta preiskovanje deviantnih ravnanj ter varovanje javne varnosti, vendar pa obstajajo posebnosti, ki jih morajo lokalne skupnosti upoštevati pri izvajanju takšnih naročil. Naročanje detektivskih storitev v lokalnih skupnostih je tako treba razumeti kot kompleksen postopek, ki zahteva premišljeno načrtovanje in upoštevanje posebnosti. S pravilno upoštevanimi pravnimi, strokovnimi in finančnimi vidiki lahko lokalne skupnosti dosežejo uspešne rezultate pri uporabi detektivskih storitev za reševanje svojih izzivov. V prispevku je opredeljena tudi analiza primera občine, ki je uporabljen kot študija primera in ponazarja izzive ter posebnosti naročanja detektivskih storitev v lokalnih skupnostih.

Authors: Kokoravec Iza , Meško Gorazd
Published: November 2023

V prispevku so predstavljeni rezultati mednarodne samonaznanitvene študije o mladoletniškem prestopništvu in viktimizaciji (ISRD4), ki jo je izvedla raziskovalna ekipa s Fakultete za varnostne vede Univerze v Mariboru v okviru programske skupine Varnost v lokalnih skupnostih. Glavni cilji raziskave so pridobiti čim realnejši vpogled v prestopništvo in viktimizacijo med mladoletniki tako na lokalni, nacionalni kot tudi na mednarodni ravni in testiranje kriminoloških teorij o prestopništvu. Osredotočimo se na mladoletnike, ki prihajajo iz gorenjske regije, in podrobneje predstavimo rezultate, do katerih smo prišli s pomočjo bivariatnih analiz, in preliminarne ugotovitve o prestopništvu in viktimizaciji. Izpostavimo posebnosti rezultatov in omejitve raziskave, v zaključku pa podamo predloge za nadaljnje raziskovanje in implikacije ugotovitev na politiko in prakso.
Zaznavanje varnostnih pojavov v slovenskih občinah: Je slovensko javno mnenje še vedno stabilno?
Authors: Tominc Bernarda , Sotlar Andrej
Published: November 2023

Podlaga za pripravo ocen ogroženosti družbe so poleg statističnih podatkov, raziskav ipd. tudi raziskave javnega mnenja. Z njihovo pomočjo se lahko identificirajo potencialne nevarnosti, tveganja ali celo grožnje. To je ključnega pomena za ustrezno pripravljenost varnostnega sistema družbe. Zaznavanje varnostnih pojavov pri prebivalstvu je izrazito subjektivna kategorija, na katero vplivajo osebne izkušnje, ozaveščenost, družbeno in fizično okolje. Čeprav raziskave kažejo, da se prebivalci Slovenije praviloma počutijo varne, oblikovalci politik in izvajalci nalog zagotavljanja varnosti zaznavanja javnosti ne smejo zanemariti. S spreminjanjem varnostnega okolja bi lahko prišlo tudi do sprememb v dojemanju varnostnih pojavov. Stabilnost javnega mnenja se izraža skozi doslednost ali trajnost stališč, prepričanj in občutkov skozi čas, v prispevku pa se nanaša na izsledke raziskav o varnostnih pojavih med letoma 2011 in 2023.
»Vaške straže« v Sloveniji: ad hoc (pravna) analiza odziva policije in drugih pristojnih organov
Authors: Flander Benjamin
Published: November 2023

V prispevku so predstavljeni izsledki ad hoc analize odziva policije (in drugih pristojnih organov) na najnovejši primer varnostnega samoorganiziranja občanov. S pretežno pravnega vidika smo ovrednotili način, na katerega so se na pojav in dejavnosti »vaške straže« v Ivančni Gorici odzvali državni organi (tj. policija). V okvirjih, ki jih določa omejitev obsega prispevka, smo odziv pristojnih institucij na vnovični pojav vigilantizma na »sončni strani Alp« primerjali z odzivom države in policije ob pojavu in dejavnostih Štajerske varde. Ugotovili smo, da je bil odziv policije ustrezen, strokovno utemeljen in sorazmeren in da je slovenski pravni red kljub noveli zakona, ki ureja varstvo javnega reda in miru, glede vprašanja »vaških straž« ostal nedorečen.

The relevance of the research is caused by the lack of study of gas hydrates and asphaltene-resin-paraffin deposits formation in the borehole space. The properties of the organic deposits formed significantly depend on conditions of their formation. Accordingly, more accurate understanding of principle of deposits formation allows predicting their agglomeration and selecting effective ways to combat the deposition of gas hydrates and asphaltene-resin-paraffin deposits. In addition, information presented in the article makes it possible to evaluate the effect of the main factors affecting the conditions of gas hydrates and asphaltene-resin-paraffin deposits formation. There is an opportunity to point out the most important factors, which can be controlled by changing the parameters of the downhole equipment. These studies can help to optimize selection of downhole equipment parameters in the conditions of organic deposits formation.  The main aim of the research is to analyze the conditions of gas hydrate and asphaltene-resin-paraffin deposits formation in production well; to analyze the results of previous studies on the factors affecting the formation of gas hydrates and asphaltene-resin-paraffin deposits in the borehole space. Objects: factors affecting formation of gas hydrates and asphaltene-resin-paraffin deposits on inner surface of the oilfield equipment. Methods: literature review of publications in peer-reviewed journals; analysis of the results of previous studies, formulation of main ideas and trends, identifying gaps and shortcomings of existing researches. Results. The main mechanisms of gas hydrates and asphaltene-resin-paraffin deposits formation on inner surface of the oilfield equipment are described. A review of previous studies devoted to the analysis of formation mechanisms of asphaltene-resin-paraffin deposits and gas hydrates is presented. The analysis revealed gaps and assumptions in the theory of formation of gas hydrates and asphaltene-resin-paraffin deposits, which require further study of their formation principles. The main factors that depend on the operation of downhole equipment, as well as affecting the formation of organic deposition are analyzed: thermal baric conditions, gas content, throttling, watering, molecular phenomena. These factors are summarized in separate tables.
Multi-faceted identities of teacher assessors: A qualitative study in the Vietnamese educational context
Authors: Yen Phuong Hoang , Thuy Pham Trut , Thao Le Thanh , Thi Nguyen Anh , Tra Nguyen Huong , Thu Huynh Thi Anh
Published: November 2023

Within the educational landscape of Vietnam, the professional identity of teachers when acting as assessors remains a comparatively uncharted domain and requires further explorations. Consequently, this qualitative investigation was initiated to delve deeper into the intricate identities Vietnamese teachers adopt in their capacities as assessors. Relying upon frameworks such as Constructivist Grounded Theory and Identity Theory, the study meticulously analyzed self-reported narratives from 15 tertiary lecturers based in Vietnam. Through this rigorous analysis, a spectrum of fifteen distinct identities was uncovered. These identities included “Gatekeepers of Knowledge and Competency”, “Nurturers”, “Diplomatists”, “Auditors”, “Confusian Sages”, “Innovators”, “Social Justice Advocators”, “Cultural Mediators”, “Emotional Anchors”, “Scalfolders”, “Technological Navigators”, “Lifelong Learners”, “Community Builders”, “Ethical Guardians”, and “Democratic Facilitators.” Intriguingly, these identities were not merely seen as additional layers to their professional duties; instead, they emerged as foundational components of teachers’ professional self-image. The forces molding these roles are diverse, encompassing deep-seated cultural values, prevailing educational paradigms, and personal lived experiences of educators. Unraveling these identities offers consequential implications for the broader educational sector. It underscores the imperative to holistically re-envision teacher training programs and assessment design, ensuring they resonate with the multifaceted roles educators play in steering both academic achievements and wider societal outcomes.
Theoretical evidence of self-intercalated 2D materials for battery and electrocatalytic applications
Authors: Fan Ke , Tsang Yuen Hong , Huang Haitao
Published: November 2023

Covalently bonded two-dimensional (2D) self-intercalated transition metal chalcogenides (i.e., ic-2Ds) have been recently fabricated experimentally, and their properties are highly tunable by stoichiometry and composition. Inspired by this progress, we focus on the applications of ic-2Ds in the field of electrochemistry and systematically investigate their performance in lithium-ion batteries (LIBs) and electrocatalytic hydrogen evolution reactions (HER). By means of density functional theory calculations, seven 3d -metal ic-2Ds are confirmed to be thermodynamically, mechanically, and thermally stable. The metallicity and abundant active sites endow these ic-2Ds with the potential as excellent electrode materials and HER catalysts. Among them, Ti7S12 and V7S12 exhibit the potential as anode materials for LIBs, showing low Li diffusion energy barriers, suitable open-circuit voltages, and ultrahigh capacity of 745.6 and 723.9 mA hg-1, respectively; Cr7S12 and Co7S12 show promises for HER with moderate hydrogen adsorption strengths. This theoretical study provides a new avenue for the application of newly reported ic-2Ds in various electrochemical energy conversion and storage applications.
A Mathematical Theory of Knowledge for Intelligent Agents
Authors: Ekolle Zie Eya , Kohno Ryuji , Ochiai Hideki
Published: November 2023

Knowledge is a property that measures the degree of awareness of an agent about a target in an environment. The goal in conventional intelligent and cognitive agent development is to build agents that can be trained to gain knowledge about a target. The definition and operations of this knowledge associated to the agent is not clear, whereas these are required for developing a reliable, scalable and flexible agent. In this paper, we provide a concise theoretical framework for the description and quantification of the knowledge property needed for an efficient design of cognitive and rational intelligent agents. We relate the quantification scheme to the epistemological description of knowledge and present many illustrative examples on the usefulness of the quantification scheme.
Mossbauer Spectroscopy Investigation of Thulium Oxide-Hematite Magnetic Ceramic Nanostructures
Authors: Stipetich Elena , Glasser Sarah , Sorescu Monica
Published: November 2023

Magnetic ceramic nanoparticles system xTm2O3-(1-x)alpha-Fe2O3 (x=0.1 and 0.5) was synthesized by mechanochemical activation starting from hematite and thulium oxide precursors and characterized by transmission Mӧssbauer spectroscopy. The Mӧssbauer spectra were typically analyzed considering 1-3 sextets, corresponding to hematite (with and without thulium doping) and a doublet, representing thulium iron perovskite (thulium orthoferrite). The magnetic hyperfine fields (BHF) and doublet abundance were studied as function of the ball milling time (BMT) for both molar concentrations employed. The results are consistent with the formation of solid solutions in the investigated system. The mixed-oxide nanoparticle system synthesized may have important applications in displays, sensors and photovoltaics, and is paving the way for emerging utilizations related to mechanically flexible electronics.
Applications of Business Simulation Games in Flipped Classrooms to Facilitate Student Engagement and Higher-Order Thinking Skills for Sustainable Learning Practices
Authors: Hsu Ching-Yun , Wu Ting-Ting
Published: November 2023

Embracing innovative digital technologies within educational systems is essential for overcoming challenges in modern learning environments, especially in the post-COVID-19 era. Teaching sustainability management in higher education institutions with innovative digital tools plays a fundamental role in the transition toward sustainable societies. Suitable game design elements play a significant role in facilitating sustainable learning. This study explored the effectiveness of incorporating business simulation games with project-based learning (PBL) in a flipped classroom setting. This approach was adopted within the context of a university cross-border e-commerce course to prepare students for acquiring 21st -century skills as higher-order thinking skills in a rapidly changing educational landscape. A quasi-experimental method was employed, involving a total of 60 university students from China's Zhejiang Province. Participants completed an online questionnaire designed to assess their learning engagement across three dimensions (cognitive, emotional, and behavioral) as well as their higher-order thinking skills (problem-solving, critical thinking, and creativity). The results show that the business simulation games combined with flipped classroom learning had a significantly positive impact on students’ learning outcomes, enhancing their problem-solving, critical thinking, and creative capabilities. Importantly, this approach also improved student engagement and promoted sustainable practices by applying real-life scenarios in an interactive environment. We conclude that business simulation games integrated with project-based learning (PBL) in flipped classroom settings represent a valuable educational approach. This approach not only enhances learning engagement but also fosters the development of higher-order thinking skills, encouraging students to adopt sustainable learning practices.
Potential Dam Breach Flood Hazard Assessment of Kulekhani Reservoir Rock Fill Dam Using 2D Diffusion and Full Dynamic Shallow Water Equation Defining Coriolis Effect
Authors: Pandey Binaya Raj , Knoblauch Helmut , Zenz Gerald
Published: November 2023

Dam breaches have catastrophic consequences, causing severe property damage, life loss, and environmental impact. The Kulekhani reservoir rockfill dam break was studied to evaluate the downstream impact. The appropriate breaching parameter of MacDonald and Langridge (1984) regression equations was selected based on the sixteen observed dam failure cases and cross-sectional geometry of the existing dam of Kulekhani. The 2D Diffusion Wave and Full Dynamic Wave Equation were applied for downstream flood assessment, Full Dynamic Wave was able to capture the physical flow phenomena like river bend effects resulting in higher flow velocity at the outer bend, and formation of eddies considering losses. The application of a Full Dynamic Equation was found to be appropriate for rapidly varying unsteady flow considering steep slopes, and sudden changes in channel geometry. Flood mapping of water depth, flow velocity, flood intensity, and arrival time were carried out for flood hazard assessment classified by the American Society of Civil Engineers (ASCE). Flow depth and extension of the flow area were compared to identify the affected area, higher flow depth and larger extension were observed using a Full Dynamic Wave Equation as a result of less flow velocity considering the losses. Almost 17 minutes of the arrival time of peak difference at the Bagmati River confluence was evaluated between the models which plays an important role in decision-making for selection of the flood model. Flood mitigation with river diversion works through a hydraulic measure of Levee was suggested to protect the highly affected households of Ranche, Nagmar, Khanikhet, and Debaltar towns. Most of the household was found to be safe after the construction of the Levee except for eleven houses that lie along the river below flood elevation of 1269.6 m.a.s.l. This signifies the importance of room for the rivers and the human settlement near the river might be life-threatening.
Effects of Restoration Strategies on the Ion Distribution and Transport Characteristics of Medicago sativa in Saline-Alkali Soil
Authors: Yu Baole , Chen Lingling , Baoyin Taogetao
Published: November 2023

Studying the distribution and transport dynamics of cations in plants is crucial for understanding their response mechanisms to saline-alkali stress conditions. However, our current understanding of how restoration measures affect cation distribution and transport in plants is surprisingly limited. To address this gap, we conducted a split-plot experiment using Medicago sativa L. cv. “Zhongmu No. 1” to investigate the combined effects of biological and chemical restoration measures—with bio-fertilizer as the primary zone and flue gas desulfurization (FGD) gypsum with humic acid as the secondary zone—on soil properties, plant growth, and the content, distribution, and transport of cations in plants. The results revealed that different restoration strategies decreased soil alkalinity and enhanced plant growth. Significantly, bio-fertilizer exhibited positive effects on plant growth and yield. On the contrary, FGD gypsum with humic acid reduced the soil's pH level, exchangeable sodium percentage, and sodium adsorption ratio, while increasing the contents of K+, Ca2+, and Mg2+ in the soil. The triple combination of FGD gypsum and humic acid with bio-fertilizer reduced Na+ transport in M. sativa by enhancing the selective absorption of beneficial ions, such as K+, Ca2+, and Mg2+ in leaves, and by facilitating the transport of Ca2+ and Mg2+ from roots and stems to the leaves. Therefore, the application of FGD gypsum and humic acid combined with bio-fertilizer has the potential to decrease soil alkalinity and the proportions of water-soluble ions in the soil, ultimately enhancing the translocation of key ionic components to leaves. This, in turn, increases the salt tolerance of plants and promotes their growth. Our results offer new insights into the interactions among measures, soil, and plants in saline-alkali land restoration, providing practical solutions for the restoration of saline-alkali soil.

This article aims to analyze residential segregation by race (racial segregation) and income (economic segregation) in Brazil and explore its relationship with socioeconomic and socio-spatial factors. Residential segregation was assessed using the dissimilarity index based on the 2010 demographic census and considering urban census tracts since segregation is sociologically considered an urban problem. The results for racial segregation showed that it is more evident in cities in the South and Southeast of Brazil and mainly affects the self-declared black population. The approach used to calculate economic segregation involved examining the income level of different low-income groups. Therefore, we consider families that earned between 0 and 1 minimum wage as the group with the greatest social vulnerability. We did not find significant correlations between racial and income segregation indices with aspects such as urbanization (urban population size). Finally, we present the racial segregation indices stratifying families by income thresholds for the 27 Brazilian capitals and conclude that per capita household income is a preponderant factor for the segregation of the poorest, especially in families whose residents self-identify as black.

Published: November 2023

Arapaima gigas is an Amazon specie with great commercial demand and high production performance, but its feasibility is variable. The current study aimed to perform an economic evaluation of the production of A. gigas on earth ponds in San Martin, Peru. Three hundred young fish (19 ± 0.01 cm and 68.32 ± 0.01 g) were stocked (ten fish·m–2 in three ponds of 1000 m2 for 390 days). Growth performance was evaluated based on the survival, feed conversion rate (FCR), final mean weight, final average length, weight gain, specific growth rate, and productivity. Investment, costs, indicators, and feasibility were determined. Arapaima gigas has a profitable production performance in earth ponds in Peru, fish presented a weight gain (kg) of 11 kg in 390 days and productivity of 3,265.70 kg·ha–1. Food and fingerlings were the most important items in the production cost. This production is a low-investment and high-profitable business, with an incremental investment of US$3,287.15, profit of US$ 3,977.38·cycle–1, Net Present Value of US$ 22,149.37, and an Intern Rate Return of 32.28%. This could be a way of increasing the income of small producers through the diversification of their production.
