Spatial Models for Identifying Factors in Student Academic Achievement
Authors: AISDL
Published: December 2020

In the literature, estimation results of the determinants of academic achievement are controversial. There may be several reasons for these controversial results, including sample or cultural differences. Conversely, these results may arise from ignoring certain important facts, such as an interaction effect. Some studies do not consider interactions among students, and some studies may not use effective models. Surprisingly, very few studies have focused on student academic achievement using spatial models, which may be one of the most suitable models for testing interaction effects. In this study, we estimated student achievement using spatial models and a data sets from Turkey. We observed an interaction between students who live in the same neighbourhood and found evidence of an interaction among students in terms of their achievement based on a spatial error model.

Thermal Adsorption Processing of Hydrocarbon Residues
Authors: Al-Obaidi Sudad H , NI Guliaeva
Published: December 2020

The raw materials of secondary catalytic processes must be prerefined. Among these refining processes are the deasphalting and demetallization including their thermo adsorption (or thermo-contact adsorption) variety. In oil processing, four main processes of thermo-adsorption refining of hydrocarbon residues are used—Asphalt Residual Treating- residues deasphaltizing (ART), Discriminatory Destructive Distillation (3D), developed in the US; Adsorption-Contact Treatment (ACT) and Express Thermo-Contact Cracking (ETCC), developed in Russia. ART and ACT are processes with absorbers of lift-type reactor, while 3D and ETCC processes are with an adsorbing reactor having ultrashort contact time of the raw material with the adsorbent. In all these processes, refining of hydrocarbon residues is achieved by partial thermo-destructive transformations of hydrocarbons and hetero-atomic compounds with simultaneous adsorption of the formed, on the surface of the adsorbents, resins, asphaltene and carboids, as well as metal-, sulphur-, and nitro-organic compounds. Demetallized and deasphalted light and heavy gas oils or their mixtures are a quality raw material for secondary deepening refining processes (catalytic and hydrogenation cracking, etc.), since they are characterized by low coking ability and low content of organometallic compounds that lead to irreversible deactivation of the catalysts of these deepening processes.

Mixing memory and desire: How memory reactivation supports deliberative decision-making.
Authors: Wang Shaoming , Feng Samuel Franklin , Bornstein Aaron
Published: December 2020

Memories affect nearly every aspect of our mental life. They allow us to both resolve uncertainty in the present and to construct plans for the future. Recently, renewed interest in the role memory plays in adaptive behavior has led to new theoretical advances and empirical observations. We review key findings, with particular emphasis on how the retrieval of many kinds of memories affect deliberative action selection. These results are interpreted in a sequential inference framework, in which reinstatements from memory serve as “samples” of potential action outcomes. The resulting model suggests a central role for the dynamics of memory reactivation in determining the influence of different kinds of memory in decisions. We propose that representation-specific dynamics can implement a bottom-up “product of experts” rule that integrates multiple sets of action-outcome predictions weighted on the basis of their uncertainty. We close by reviewing related findings and identifying areas for further research.
vICC: Varying Intraclass Correlation Coefficients in R
Authors: Williams Donald Ray
Published: December 2020

In mixed-effects (a.k.a, hierarchical or multilevel) models, intraclass correlation coefficients (ICC) are commonly computed, with applications spanning from characterizing group-level homogeneity to measurement reliability. While there are a wide spectrum of applications, an underlying assumption of each is that the variance components used in their computation are fixed and non-varying. The methodology in the R package \textbf{vICC} was specifically designedto quantify variation in the ICC. This can be used to identify groups that are more (or less) homogeneous, as well as which groups are adequately described by the non-varying ICC. I end with future directions.
Why and how to engage expert stakeholders in ontology development: Insights from social and behavioural sciences
Authors: Norris Emma , Hastings Janna , Marques Marta M , Finnerty Ailbhe Noelle , Zink Silje , Michie Susan
Published: December 2020

Background: Incorporating the feedback of expert stakeholders in ontology development is important to ensure content is scientifically sound, comprehensive, meets community needs and is interoperable with other ontologies and classification systems. However, domain experts are often not formally engaged in ontology development, and there is little available guidance on how this involvement should best be conducted and managed. Social and behavioural science studies often involve expert feedback in the development of tools and classification systems but have had little engagement with ontology development. This paper aims to i) demonstrate how expert feedback can enhance ontology development, and ii) provide practical recommendations on how to conduct expert feedback in ontology development using methodologies from the social and behavioural sciences.Main body: Considerations for selecting methods for engaging stakeholders are presented. Mailing lists and issue trackers as existing methods used frequently in ontology development are discussed. Advisory boards and working groups, feedback tasks, consensus exercises, discussions and workshops are presented as potential methods from social and behavioural sciences to incorporate in ontology development.Conclusion: A variety of methods from the social and behavioural sciences exist to enable feedback from expert stakeholders in ontology development. Engaging domain experts in ontology development enables depth and clarity in ontology development, whilst also establishing advocates for an ontology upon its completion.
The Self-Reflection and Insight Scale: Applying Item Response Theory to Craft an Efficient Short Form
Authors: Silvia Paul
Published: December 2020

The human ability for self-consciousness—the capacity to reflect on oneself and to think about one’s thoughts, experiences, and actions—is central to understanding personality and motivation. The present research examined the psychometric properties of the Self-reflection and Insight Scale (SRIS), a prominent self-report scale for measuring individual differences in private self-consciousness. Using tools from Rasch and item response theory models, the SRIS was evaluated using responses from a large sample of young adults (n = 1192). The SRIS had many strengths, including essentially zero gender-based differential item functioning (DIF), but a cluster of poor performing items was identified based on item misfit, high local dependence, and low item difficulty and discrimination. Based on the IRT analyses, a concise 12-item scale, evenly balanced between self-reflection and insight, was crafted. The short SRIS showed strong dimensionality, reliability, item fit, and local independence as well as essentially no gender DIF. Taken together, the many psychometric strengths of the SRIS support its popularity, and the short form will be useful for research and applied contexts where an efficient, concise version is needed.
Folk intuitions about reference change and the causal theory of reference
Authors: Wiegmann Alex , Koch Steffen
Published: December 2020

In this paper, we present and discuss the findings of two experiments about reference change. Cases of reference change have sometimes been invoked to challenge traditional versions of semantic externalism, but the relevant cases have never been tested empirically. The experiments we have conducted use variants of the famous Twin Earth scenario to test folk intuitions about whether natural kind terms such as ‘water’ or ‘salt’ switch reference after being constantly (mis)applied to different kinds. Our results indicate that this is indeed so. We argue that this finding is evidence against Saul Kripke’s causal-historical view of reference, and at least provisional evidence in favor of the causal source view of reference as suggested by Gareth Evans and Michael Devitt.
Drawing a Line: Comparing the Estimation of Top Incomes Between Tax Data and Household Survey Data
Authors: Yonzan Nishant , Milanovic Branko , Morelli Salvatore , Gornick Janet C.
Published: December 2020

The paper uses the flexibility of household survey data to align their income categories and recipient units with the income categories and units found in data produced by tax authorities. Our analyses, based on a standardized definition of fiscal income, allow us to locate, for top-income groups, the sources of discrepancy. We find, using the cases of the United States, Germany, and France, that the results from survey-based and tax data correspond extremely well (in terms of total income, mean income, composition of income, and income shares) above the 90th percentile and up to the top 1 percent of the distribution. Information about income composition, available in the US, allows us to investigate the determinants of this gap in the US. About three-fourths of the tax/survey gap is due to differences in non-labor incomes, especially self-employment (business) income. The gap itself may be due to tax-induced re-classification of income from corporate to personal or/and to lower ability of surveys to capture top 1 percent incomes.

Italian Cinema and the World Cinema Stress Test
Authors: Caminati Luca
Published: December 2020

L’auteur propose quelques réflexions sur l’application d’une méthodologie postcoloniale à l’étude du cinéma mondial en contexte national, en mettant de l’avant une notion élargie du cinéma national italien en ce qui a trait à son corpus (ce en quoi consiste un film italien), à son vocabulaire (accentué, migrant, mondialisé) et à sa méthodologie. Il analyse pour ce faire deux réactions secondaires aux documentaires africains de Pier Paolo Pasolini, En attendant Pasolini ( Waiting for Pasolini, Daoud Aoula-Syad, 2007) et Pasolini Pa* Palestine (Ayreen Anastas, 2005). Ces deux films sont non seulement des réponses géopolitiques probantes au nouvel ordre mondial de mondialisation, mais de réels échanges avec et sur les codes du cinéma italien et son legs mondial dans notre situation postcoloniale actuelle.

Management of out-of-hospital cardiac arrest (OHCA) remains challenging, particularly in young patients.
Takayasu arteritis is a rare large-vessel vasculitis relatively. Coronary involvement has been previously
described; we provided the first intracoronary images by OCT. We report the first case of OHCA with
shockable rhythm revealing chronic total occlusion of the left main in a 41-year-old lady. The coronary
anomaly made it possible to diagnose the vasculitis and to treat it by corticosteroid and immunosuppressive
treatment. Vasculitis should be evoked in atypical coronary syndrome in young patients. A collaborative
multidisciplinary approach permits optimal care for this complex patient.

The origin and nature of consciousness: problem statement
Authors:   Vasyl Stefanyk Precarpathian National University, Hoian I. , Kychkyruk T. ,   National University of Life and Environmental Sciences of Ukraine
Published: December 2020

The problem of the origin of consciousness has intrigued researchers for centuries. Every thinker has interpreted this problem in a unique way, and therefore several concepts of the origin of consciousness have been proposed. There are: the theological concept according to which human’s consciousness is a gift of God; the dualistic concept that focuses on the fact that our mind is not identical with our brain; the labor concept of anthroposociogenesis, which is based on the fact that matter in its self-development under certain conditions generates consciousness; the evolutionary concepts (Darwinism and Neo-Lamarckism); the spiritual evolutionism of P. Teilhard de Chardin; the filed theories of consciousness, which interpret consciousness as identical to the field in the general sense (W. Köhler, B. Libet), the electromagnetic field theory of consciousness; J. Hagelin’s unified field theory of consciousness; the concept of a single information field. The origin of consciousness is one of the most puzzling mysteries of the human mind due to the inherent conceptual and theoretical difficulties. We still do not know much about the work of the brain; we do not know exactly what underlies its higher functions and human consciousness. However, in recent years, the progress in this area is evident. Consciousness cannot be explained by appealing to the only one area of scientific knowledge. Therefore, today, it is necessary to develop a new interdisciplinary approach to the new theory of consciousness, which will reveal the multifaceted nature of a human and humanity. Further understanding of the phenomenon of consciousness and its origin requires the cooperation of representatives of different disciplines, the creation of the unified platform for interaction between all branches of knowledge. The purpose of the article is to analyze the theories of the origin and nature of consciousness.
Ахеменидская цилиндрическая печать из Косики
Authors:   Deutsches Archäologisches Institut, Трейстер М.
Published: December 2020

This article is devoted to the Achaemenid cylinder seal, representing a fight of the Persian hero with two lions, from the princely burial in Kosika in the Lower Volga region dated to the third quarter of the 1st century BC. The analysis has shown that the seal is dated to the 5th century BC, more likely to its first half. There is a good chance that it could be carved in a peripheral workshop in Mesopotamia or in Syria. The seal, made of a high quality-material at the high level, represents a complicated and in certain aspects very rare composition, clearly standing out in the context of the Achaemenid glyptics. At least 400 years passed between the time the seal had been carved and its use as part of the burial inventory in Kosika. It is hardly to suggest that the seal belonged to nomads all this time, especially since the finds of the Achaemenid seals in the nomadic burials in Eurasia of the 5th–4th centuries BC are extremely rare, unlike their finds in the necropoleis of the Bosporan Kingdom. The Achaemenid seal from Kosika along with a Kassite cylinder seal found in the same burial belongs to the circle of the Western Asian and Near Eastern seals of the mid-2nd — mid-1st millennium BC which were found also in the burials of Sarmatian elite of the 1st century BC — early 2nd century AD in the Bug, the Don and the Kuban regions. They probably fell into the hands of the nomads during robbery of sanctuaries at Transcaucasia.
Боспорские «Ники»
Authors:   Институт истории материальной культуры РАН, Шауб И.
Published: December 2020

This article is devoted to refuting of an established concept according to which female winged anthropomorphic characters at monuments of ancient art found in Bosporan burial mounds depicted Nike. The presence of the goddess of victory on object from burial inventory has not been explained. The author assumes that a female role at iconography of Nike has been reconsidered. The images on important ritual objects allow suggesting that barbarian inhabitants of the Bosporus saw their own goddess in the image of the winged woman, one of incarnations of the Great goddess.
Некоторые замечания к образу скифской полуженщины-полузмеи у Геродота
Authors:   Институт всеобщей истории РАН, Подосинов А.
Published: December 2020

This article analyses the image of half-woman-half-snake described by Herodotus in IV, 9. She was known to be an ancestress of the Scythians. We will also look at numerous images of a goddess who is often seen as either an iconographic variant of Herodotus’ character or a “sprouting maiden” (Rankenfrau). The analysis involves descriptions of maidens with lower part in the form of a grape plant in Lucian’s “A True Story” which obviously parodies the Herodotus’ text. Lucian also has other episodes of such caricature. For example, he references to large footprints on a rock that Dionysos and Herakles would have left (I, 7) which refers to Herodotus’ tale about Herakles footprint on a rock near the Tyras river (IV, 82). Lucian’s evidence probably confirms an opinion of historians who see “sprouting maidens” in the images of North Black Sea region goddesses.
Между Вифинией и Борисфеном: от ристалища Ахилла на Кальпе к прибытию Афродиты в Гилею

Published: December 2020

Dionysios of Olbia is known only from a few words quoted in connection with the river Kalpe on the north coast of ancient Bithynia. The author is usually believed to be one of a very few from the northern Black Sea, but that is unlikely. The Greeks usually called the Pontic city of Olbia by the name Borysthenes. In addition, this author clearly wrote about a detail of the mythical topography of the river Kalpe, where Achilles was said to race (as at Tendra and on Leuke): the topic and use of the name Olbia suggests that we should probably locate Dionysios among the many Bithynian writers on such matters, since an Olbia was part of the Bithynian royal capital, Nicomedia. The obscure Demosthenes of Bithynia is discussed as an example of this kind of work, as also Pseudo-Scymnus. Shared mythical links between Bithynia, neighbouring regions. and the north-western Black Sea may suggest that Aphrodite Ourania (who had not come from Miletos) was believed to have come to Olbia by way of the Sea of Marmara, as Greek sailors did.

The paper deals with all kinds of sources concerning the final stage of the Scythian history in the area of the Tanais river mouth. Comprehensive analysis of archaeological materials shows that the crisis, which led to the end of the Great Scythia, started long before the turn of the 3rd century BC. In the 3rd quarter of the 4th century BC the Elizavetovskoe settlement was attacked by the Bosporan Kingdom. Consequently, a Greek quarter was founded within the Scythian settlement, and it is highly possible that the Scythians lost some of their control over the region. At the end of the 4th century BC the Bosporan Kingdom finally conquered the Elizavetovskoe settlement, displaced its Scythian population and founded the Great Greek colony at the place. At the same time other Scythians stayed in the region. In the mid 70s of the 3rd centure BC, a sudden military attack destroyed the unfortified Greek colony. That concludes the Scythian history of the region. There is no evidence that the Sarmatians took part in the events of second half of the 4th — first half of the 3rd century BC. Tanais, a new Bosporan colony, was founded in the mouth of the Don river delta. It was during another stable period in the Northern Black Sea region, so up to the turn of the 2nd century BC Tanais had no fortifications.
Любые античные вазы из Северного Причерноморья: путешествие к трансцендентальному

The author analyzes the historical background for collecting and trading in the ancient painted pottery (Corinthian, Boeotian, Euboean, Greek geometric, Italiote, Cypriot) which was considered as finds from the South Russia (Crimea, Odessa region and Taman peninsula) during 1890–1910s. At that time these specimens of ancient pottery played an important role as an element bringing more colors to the expected image of “the Classical Hellas in the South Russia”. The pieces are currently available for studies in various Russian museums.

The authors of this paper describe the face transport system that ensures the stripping of ore bodies using the underground development method with inclined narrow workings driven downward, including in conditions of increased water cut. The face transport system will allow the preparation of a new 500-thousand-ton mine with minimum general construction and mining construction works as well. The article contains an engineering study of the transition of the road heading to blastless continuous-flow methods of rock development using hydraulic impulse or mechanical shock machines, which are under development. For deep and ultra-deep developments starting from 250-300 m and deeper, a new technical solution is given for the construction of a downhole mine airlift with the lowest capital and operating costs and sufficiently high reliability and productivity. New technical solutions will ensure the radical transition of the technological concept of mining production from the drilling-and-blasting cyclic to blastless continuous-flow one.
On the problem of utilization of carbon dioxide in waste gases of power plant boilers when burning high-ash coals

Published: December 2020

The production activity of mankind using high-ash fossil fuels for electricity generation is steadily increasing ash waste and carbon dioxide emissions into the environment. The article proposes a variant of wasteless combustion of Ekibastuz coal in a melting reactor installed under the boiler; it is envisaged to obtain, in addition to steam of energy parameters, a melt suitable for the production of building materials, sublimates of zinc, gallium and germanium, to reduce emissions of " СО2" into the atmosphere and return to the process a part of carbon in " СО2". An energy-saving thermal diagram of a power plant boiler has been developed on the basis of the proposed technology for the reduction of " СО2, Н2О " of reactor waste gases with zinc vapor to " СО, Н2". The resulting excessive hydrogen will be used to displace elemental carbon from "CO". The spent reagent, zinc oxide, after recovering into zinc will be used again in the process. In case of implementation, CO2 emissions into the atmosphere will be cut up to 50%, the expected payback period of the proposed system will be 1.0 - 1.5 years.

The process experts are concerned in tellurium due to its various physical and chemical properties. The copper anode slime is the main industrial source of tellurium, after processing of that tellurium becomes marketable product and can be sold both in elemental form and tellurium-containing middling. Physical and chemical properties of the tellurium-containing middling of Kazakhmys Smelting LLP produced in 2018 have been studied in this paper. The following methods have been applied during the study: particle size distribution, X-ray phase, X-ray fluorescence and scanning electron probe microscopy. It was found that material is mainly represented by the large pieces of 0.2 mm in size, with moisture content of 15.57 %, bulk density of 0.8 g/cm3 without tapping and 0.88 g/cm3 with tapping, the angle friction - 33°. The elemental composition of the material was determined by X-ray fluorescence method as follows, wt. %: Cu – 33.327; Te – 21.863; Se – 0.766, O – 35.116; S – 5.045. X-ray phase analysis showed that material is mainly in the amorphous state, the following phases had been identified: Cu2.5SO4(OH)3·2H2O, Cu3(SO4)(OH)4, CuSO4(H2O)3. Tellurium-containing phases could not be detected due to strong amorphism. Hydrosulfate forms of copper in the form of flakes have been found on the surface of the middlings by electron probe microscopy. EDS analysis of individual areas showed that patina also contains small amounts of chlorine, selenium and up to 25 % tellurium, in addition to such elements as copper, sulfur and oxygen. Small amounts of sulfur, chromium, selenium and up to 45 % of oxygen has been found in the open area of material, that is specific for its oxidation.

The article presents the results of calculating the material and thermal balances of refined ferrochrome (RFeCr) smelting using a new reducing agent. According to the results of the material balance and enlarged laboratory tests, it was found that when the traditional reducing agent silicochrome (FeSiCr48) is completely replaced with a complex alloy of aluminosilicochrome (FeAlSiCr), a metal of the following chemical composition can be obtained, %: Cr 66.8-69.1; C 0.21-0.29, Si 1.91-2.02. The composition of FeAlSiCr for silicon and chromium is the same as that of FeSiCr48, but additionally contains Al. In the process of obtaining refined ferrochrome, this aluminum passed into slag and changed its phase composition. In the CaO-MgO-Al2O3-SiO2 system, the phase composition of the slag moved from the region of bicalcium silicate to the region of helenite, which allowed to obtain non-crumbling slags. In addition, due to the high activity of FeAlSiCr (where, ∑ = Si + Al ≥ 60%), the basicity of the slag was maintained at the level of CaO/SiO2 = 1.6-1.7, against to 2. Based on the results of the heat balance calculation, it was found that the use of a complex FeAlSiCr reducing agent leads to a 24% reduction in electricity consumption. The low power consumption compared to the classical technology is explained by the presence of two active elements in the FeAlSiCr, silicon and aluminum. Thus, the amount of heat introduced by exothermic reactions prevails with the heat introduced by electrical energy.

The paper offers the measuring results for hydrogen permeability of the membranes made of 40 μm thick tantalum foil covered with a metallic film with different thicknesses on one side. The measurements were performed when the membranes were in contact with a commercial argon and hydrogen gases mixed at the ratio of 1/5 at an overpressure of 500 kPa and at 580-585°C. It is shown that films of Mo, Re, W, Cu, Co, and Ni metals deposited on the tantalum membrane surface from the side facing a hydrogen-containing gas mixture increase its hydrogen permeability. The effect degree of these metals increases in the specified row from left to right. The effect on the hydrogen permeability of tantalum membranes, comparable to and superior to the deposition of a Pd film, exerts the deposition of Cu, Co, and Ni films. It is explained by the high hydrogen permeability level of these metals and the catalytic activity of their surface that results in intense hydrogen dissociation. The value of the hydrogen permeability of the membranes naturally increases with a thickness decrease of metallic films, however, it is obvious that this behavior is not linear. The hydrogen permeability of membranes with Cu, Co, and Ni films decreases over time, that is explained by the oxygen segregation at the Ta membrane/film interface, as well as by the processes on the membrane surface in contact with the gas mixture. The nature of these processes should be studies since the lower oxides of these metals are reduced by hydrogen at this temperature.

This article evaluates the effects of urbanization on the land use within the Chisinau agglomeration. The research carried out regarding situation in Stăuceni commune, confirms that the peri-urban area, undergoes a period of significant spatial and functional transformation, influenced by the demographic pressure, poorly controlled urban development and the intensification of the land relations. By implementing the project “Chisinau Arena” on the territory of Stăuceni commune, the plan for territorial expansion of Chisinau city (in peri-urban areas located on major transport axes) is reconfirmed. At the same time, the demographic forecast presented in scenario III, according to UN for population, shows that the Chisinau population will decrease dramatically, towards 2035, therefore it is necessary that the spatial planning plans to be adapted quickly to the pace of demographic changes, to avoid compromising the infrastructure projects and squandering land in the suburban areas.
Tax subsidies for entrepreneurs in case of property tax
Authors: Jóźwiak Edyta
Published: December 2020

In Polish tax law, real estate is subject to taxation. Property tax rates depend not only on the type of property but also on the taxable person. Thus, as far as persons conducting business activity are concerned, real estate in their possession is taxed at a higher rate than that of natural persons. The amount of the tax payable annually may exceed the income of the trader concerned, since it does not depend on the taxable person's financial situation (as is the case with other taxes, e.g. personal income tax). Due to this fact, a catalog of tax reliefs and exemptions, i.e. the so-called tax subsidies, as well as the possibility of spreading the tax in instalments and deferring its payment date is an important role in real estate tax. The state, including municipalities, may create this form of aid, as long as it does not conflict with the provisions of the Act on State Aid and similar provisions in force in the European Union, which are designed to observe free competition in the market. The purpose of this Article is to indicate what are the current forms of assistance to entrepreneurs on the example of property tax.
