Authors: Peters Manuel J.H. , Goren Yuval , Fabian Peter , Mirão José , Bottaini Carlo , Grassini Sabrina , Angelini Emma
Published: December 2022

The research presented in this paper focused on the preliminary non- and semi-destructive analysis of copper alloys, corrosion, and soil components from a Roman archaeological site in Israel. Investigations using portable X-ray fluorescence, X-ray diffraction and scanning electron microscopy with energy dispersive spectroscopy as well as micromorphological analyses were carried out to gain a better understanding of the corrosion processes affecting the copper alloy artefacts, by characterising the alloy composition, soil environments, and corrosion products. Preliminary results indicate that the artefacts consist of copper-lead-tin alloys, covered by copper hydroxy-chlorides and lead sulphate phases with slight variations in their crystallisation. The multi-analytical approach revealed the presence of quartz, calcite, gypsum and feldspars in the sediments, while thin sections more specifically indicate loess soils with local micro-environments
How the COVID-19 changed the hands-on laboratory classes of electrical measurement
Authors: Svatos Jakub , Holub Jan
Published: December 2022

This article depicts how COVID-19 affected practical teaching at Czech Technical University in Prague, Faculty of Electrical Engineering, Department of Measurement. It introduces the subject of Electrical Measurement and its hands-on laboratory classes. The course applies to more than 100 undergraduate students per semester. Since COVID-19 mainly affected the teaching of the hands-on laboratory courses, the article narrates how the COVID-19 lockdown has changed classes. An experience with the rapid transformation of lectures during the lockdown focusing on the hands-on laboratory classes is discussed, and the improvements that have been done to preserve its objectives, but also to adapt them to another possible lockdown, and the need to switch to the distance teaching, is revealed. The changes have been inspired by the results of a survey carried out among more than 250 students. The outline of the laboratory tasks transformation with an emphasis on the possibility of switching the real face-to-face measurement to the distance teaching remote lectures is described. The change includes reducing the number of laboratory tasks taught while preserving most of the objectives. All 11 new laboratory tasks are described in detail, and it is discussed how the possible change from hands-on to remote classes will affect every task.
Biomechanics in crutch assisted walking
Authors: Crenna Francesco , Lancini Matteo , Ghidelli Marco , Rossi Giovanni B. , Berardengo Marta
Published: December 2022

Crutch-assisted walking is very common among patients with a temporary or permanent impairment affecting lower limb biomechanics. Correct crutches’ handling is the way to avoid undesired side effects in lower limbs recovery or, in chronic users, upper limbs joints diseases. Active exoskeletons for spinal cord injured patients are commonly crutch assisted. In such cases, in which upper limbs must be preserved, specific training in crutch use is mandatory. A walking test setup was prepared to monitor healthy volunteers during crunch use as a first step. Measurements were performed by using both a motion capture system and instrumented crutches measuring load distribution. In this paper, we present preliminary tests results based on different subjects - having a variety of anthropometrical characteristics - during walking with parallel or alternate crutches, the so-called three and two-points strategies. Tests results present inter and intra subject variabilities and, as a first goal, influencing factors affecting crutch loads have been identified. In the future we aim to address crutch use errors that could lead to delayed recovery or upper limbs suffering in patients, giving valuable information to physicians and therapists to improve user’s training.
Position control for the MSL Kibble balance coil using a syringe pump
Authors: Hawke Rebecca J , Clarkson Mark T
Published: December 2022

The position of the coil in a Kibble balance must be finely controlled. In weighing mode, the coil remains stationary to maintain a constant magnetic field. In calibration mode, the coil is moved in the magnetic field to induce a voltage. The MSL Kibble balance design is based on a twin pressure balance where the coil is attached to the piston of one of the pressure balances. Here we investigate how the piston (and therefore coil) position may be controlled through careful manipulation of the gas column under the piston. We demonstrate the use of a syringe pump as a programmable volume regulator which can provide fall rate compensation as well as controlled motion of the piston. We show that the damped harmonic oscillator response of the pressure balance must be considered when moving the coil. From this initial investigation, we discuss the implications for use in the MSL Kibble balance.
Spatiotemporal analysis of human gait, based on feet trajectories estimated by means of depth sensors
Authors: Wagner Jakub , Morawski Roman Z.
Published: December 2022

This paper addresses a methodology for the analysis of human gait, based on the data acquired by means of depth sensors. This methodology is dedicated to healthcare-related applications and involves the identification of the phases of the gait cycle by thresholding estimates of velocities of the examined person’s feet. In order to assess its performance, a series of experiments was carried out using a reference gait-analysis system based on a pressure-distribution-measurement platform. An original method for quantifying gait asymmetry, based on a quasi-correlation between the feet trajectories, was also proposed and tested experimentally. The results of the reported experiments seem to promise a high applicability potential of the considered methodology.
Technology Focus: EOR Operations (November 2022)
Authors: Fassihi Reza
Published: December 2022

Among the different enhanced-oil-recover techniques, waterflooding is still commonly practiced in part because of its economic potential. During the past 2 years, many papers presented at SPE meetings have dealt with different aspects of waterflooding design, optimization, monitoring, and low-salinity applications.

Understanding the injected-water preferential paths is a key aspect of waterflood optimization in reservoirs characterized by strong vertical and areal heterogeneities. Devising specific work flows for such applications is important. These can be easy but powerful tools for visualizing the complex dynamic connections between injectors/producers and aquifer influence areas. They can enable improving the business-time decision-making cycle, resulting in increased operational performance and lower waterflood operating costs by consolidating end-to-end optimization work flows in one platform.

Using artificial intelligence (AI) and machine-learning (ML) approaches with reduced-physics models can reduce the time required for this task. Also, ML allows for fast screening of waterflood performance at diverse levels (e.g., reservoir, sector, pattern, and well), enabling prompt identification of opportunities for immediate uptake into an opportunity-management process and for evaluation in AI-driven production forecasting or in a reservoir simulator.

As part of waterflood optimization, changing the chemistry of the injected water has been under investigation since early 2000. This process has been named differently in different laboratories (e.g., smart water and low-salinity waterflooding, or LoSal). The new studies are related to its field application. It is interesting that new hybrid applications such as low-salinity water with surfactant flooding and carbonated smart water injection are showing up in the literature. As we move forward, it is expected that the waterflooding recovery factor will increase with additional technology advancements.

Technology Focus: Hydraulic Fracturing Modeling (November 2022)
Authors: Yang Junjie
Published: December 2022

Hydraulic fracture stimulation is proven to be the economic way to develop tight unconventional reservoirs. From an operational perspective, hydraulic stimulation is well established and widely applied to most unconventional plays. There is still room for improvement, however, to increase the efficiency and deepen the understanding of the detailed mechanism in the process. Particularly in the domain of fracture simulation, significant effort has been devoted to enhance model complexity and accuracy.

Recent simulation studies have covered sophisticated mechanisms such as hydraulic fractures—natural fracture interaction, proppant transportation and settlement, casing friction, new government equations of fracture propagation, and fracture roughness. Fully coupled fracture modeling work flows with stress variation, solid transportation, and fluid flow become the mainstream, while model complexity and budget tradeoff remains challenging.

Interestingly, fracture modeling has been applied beyond hydrocarbon production. New applications include cutting injection, coal-seam-gas production, and recently evolving enhanced geothermal systems (EGS). Both industrial and academic researchers have made progress on EGS by introducing another dimension of complexity in that thermal effects alter hydraulic fracture modeling behavior.

With the advancement of powerful measurement techniques in the past decade, the industry has seen novel ways to calibrate fracture models. Other than microseismicity and pumping-schedule history matching, data collected from downhole tools such as distributed temperature and acoustic sensing and fiber-optic sensors have broader applications and show promising results. By leveraging computational power and machine-learning approaches, scaled-up modeling on the field level energizes the study of well interference, the depletion effect, and frac-hit-damage mechanisms.

A Similarity-Based Solution for Nonlinear Gas Fractional Diffusivity Equation with Application to Rate Transient Analysis of Unconventional Heterogeneous Reservoirs
Authors: Zhang Miao , Garcez Jonathan , Ayala Luis F.
Published: December 2022

Production characteristics of fractured wells in unconventional heterogeneous reservoirs have been shown to be effectively captured via anomalous diffusion model in which a partial differential equation (PDE) with fractional derivatives is solved. This paper presents a novel semianalytical solution of the nonlinear fractional diffusivity equation (FDE) applied to compressible fluid (gas) flow toward hydraulic fractures placed in heterogeneous and complex geological porous media. Self-similar theory and scaling transformation are used to solve the nonlinear PDE of fractional derivative written for real gas flow using density as the primary variable. The governing nonlinear partial gas FDE is transformed to ordinary nonlinear fractional differential equation after introducing similarity variables, which is later solved via shooting method coupled with Runge-Kutta integration. Pressure-dependent gas properties are captured straightforwardly in the solution without resorting to any further linearization via pseudopressure or pseudotime functions. The proposed similarity-based semianalytical solution is benchmarked against a Laplace transform-based analytical solution for linear, liquid FDE, and validated against a finely gridded numerical solution for the nonlinear, gas FDE. The proposed solution enables the diagnostic interpretation and characterization of production responses of unconventional gas wells exhibiting power-law behavior on the premise of anomalous diffusion during early transient period, which permits the estimation of important reservoir and fracture properties as shown in the case studies. Field and numerical examples are presented to showcase the capabilities of the proposed approach in the inverse, rate transient analysis.

Politiques fiscales, inégalités et pauvreté dans l'UEMOA : existe-t-il un paradoxe fiscal ?
Authors: Alakonon Calixe Bidossessi , ALINSATO Alastaire Sèna , ZOGBASSE Symphorien
Published: December 2022

This paper examines the existence of a tax paradox on poverty and inequality in the countries of the West African Economic and Monetary Union (WAEMU). To achieve the goal, a fixed effects model on panel data covering the period 1980 to 2019 was used. The results confirm the existence of a tax paradox for indirect taxes. Direct taxes simultaneously reduce poverty and income inequality. However, spending on health and education in WAEMU countries does not reduce poverty and income inequality. Accordingly, this paper suggests on the one hand that governments rethink the design of pro-poor tax policies so that they are net beneficiaries and not net contributors to the tax system. On the other hand, a simultaneous reduction of poverty and income inequality requires governments to target health and education spending to the poorest.

Published: December 2022

To date there are no therapeutic strategies that limit the progression of Parkinson’s disease (PD). The mechanisms underlying PD-related nigrostriatal neurodegeneration remain incompletely understood, with multiple factors modulating the course of PD pathogenesis. This includes Nrf2-dependent gene expression, oxidative stress, α-synuclein pathology, mitochondrial dysfunction, and neuroinflammation. In vitro and sub-acute in vivo rotenone rat models of PD were used to evaluate the neuroprotective potential of a clinically-safe, multi-target metabolic and inflammatory modulator, the electrophilic fatty acid nitroalkene 10-nitro-oleic acid (10-NO2-OA). In N27A dopaminergic cells and in the substantia nigra pars compacta of rats, 10-NO2-OA activated Nrf2-regulated gene expression and inhibited NOX2 and LRRK2 hyperactivation, oxidative stress, microglial activation, α-synuclein modification and downstream mitochondrial import impairment. These data reveal broad neuroprotective actions of 10-NO2-OA in a sub-acute model of PD and motivate more chronic studies in rodents and primates.
Case Study and Numerical Modeling for Liquefaction of Soil with Three Possible Phenomenons Cause of Liquefaction
Authors: Syofyan M. F. , Arudia Y. P. , Rahardjo Paulus P. , Karlinasari Rinda
Published: December 2022

An earthquake measuring 7.4 on the Richter Scale has hit Palu in Central Sulawesi. This earthquake was not the first, but until now it was the strongest earthquake. The Central Analysis of Volcanology and Geological Disaster Mitigation (PVMBG) states that a large 7.4 SR earthquake was triggered by the Palu-Koro slip-strike fault activity. Earthquakes that occurred cause liquefaction. Liquefaction basically occurs in the loose sand material. The impact of earthquake shocks that occur causes high pore water pressure; high pore water pressure causes a reduction in the effective pressure of the soil so that the soil becomes liquid. One area at the town of Palu which liquefaction occurred massively is Balaroa. There are three initial conditions that may occur at Balaroa liquefaction, the first is the soil having a high-water level due to rain, the second is the soil having high pore water pressure due to seepage and the third the soil has a high pore water pressure due to the rupture of aquifer layers. Numerical modeling was tried to model the effect of those initial conditions to see how the phenomenon of the liquefaction occurs.
When Being Selfish Prevails: The Impact of Sociality Regimes on Heterogeneous Cooperative-Competitive Multi-agent Reinforcement Learning
Authors: Zhao Yue , Hernández-Orallo José
Published: December 2022

Work in multi-agent reinforcement learning (MARL) tends to compare algorithms choosing some particular sociality regime for sharing (or not) the rewards, assuming this choice is optimal. For instance, the popular multi-agent deep deterministic policy gradient algorithm (MADDPG), when evaluated in a predator and prey game, used a different regime when acting as a predator than when acting as a prey. In this paper, we question what kind of sociality regimes (selfish, egalitarian, or altruistic) should be used in multi-agent algorithms. In the past, choices of the sociality regime have been done only for homogeneous teams, and without normalising the effect of the sociality regimes. Here we introduce a normalisation of the weights of the sociality regimes so that the sum of all rewards is independent of the sociality regime. With this, we extend the analysis to heterogeneous teams in cooperative-competitive MARL situations since team composition is very relevant to the sociality choice. We find that the selfish regime is advantageous for both prey and predator teams, and for both homogeneous and heterogeneous teams. The takeaway message is that, unlike common practice in MARL, any study of homogeneous and heterogeneous cooperative-competitive multi-agent reinforcement learning teams should also take into account the sociality regimes before making conclusions on the preference of any algorithm.
A survey of United States dermatologists' knowledge, attitudes, and practices with intramuscular triamcinolone
Authors: Kuceki Guilherme , Snyder Ashley , Hopkins Zachary , Secrest Aaron
Published: December 2022

Since the 1970s, intramuscular triamcinolone (IMT) has been available as an option for systemic corticosteroid use in dermatology. Although shown to be safe and effective in early studies, this method of systemic corticosteroid delivery fell out of favor in the 1980s in many United States residency programs. To identify factors associated with US dermatologists' preferences for and use of IMT we surveyed a random sample of US board-certified dermatologists to assess knowledge, attitudes, and practices regarding IMT in dermatologists' daily clinical practice. A total of 844 out of 2000 dermatologists completed the survey (42.2%). Only 55.0% reported feeling comfortable using IMT for steroid-responsive dermatoses, while 90.4% felt comfortable using oral corticosteroids for steroid-responsive dermatoses. Most participants (59.2%) did not prefer IMT over oral corticosteroids when both were indicated. One third (33.3%) of participants reported that none of the faculty during their residency advocated using IMT. Receiving education on IMT indications (OR = 1.96 [95% CI: 1.46-2.63]) and encouragement to use IMT (OR = 4.29 [95% CI: 3.01-6.11]) during residency were positively associated with use of IMT at least once a month in current practice. Current knowledge, attitudes, and practices surrounding IMT vary amongst practicing dermatologists. Modifiable factors such as training could improve comfort with use of this short-term systemic steroid treatment modality.
Snowball critical velocity to nucleate quantized vortex in isotopically pure 4He
Authors: Takahashi Daisuke , Ikegami Hiroki , Kono Kimitoshi
Published: December 2022

The critical velocity for vortex nucleation of snowball (positive ion) is determined experimentally in isotopically purified 4He at temperatures down to 50 mK. Systematic I-V characteristic measurements for the two-dimensional snowball pool at the depth of 37.6 nm from the surface are carried out with an extremely fine control of driving electric fields. The critical velocity of ∼ 32 ms-1 at 500 mK decreases with lowering temperature and approaches a temperature independent value of ∼ 18 ms-1 below 200 mK. The decrease of critical velocity corresponds to the increase of the nucleation rate. The temperature dependence of the critical velocity is qualitatively attributed to the "superohmic" macroscopic quantum tunnelling developed by Caldeira and Leggett. The reduction of the tunnelling rate by increasing temperature is an evidence for the quantum friction.

Today, institutional and private investors face the problem of an objective investment assessment of companies when investing their funds. Fundamental financial indicators of companies do not always fully reflect their efficiency, including when using fuel and energy resources. This problem is especially relevant for energy companies that consume a significant amount of fuel and where excess fuel losses are often included in the tariff to the consumer. In this work, the object of the research is various energy companies in Russia, whose shares are traded on the Moscow Exchange. The subject of the research is the investment attractiveness of large energy companies with an emphasis on their energy efficiency. The purpose of the research is to develop a new way to assess the investment attractiveness of large energy companies, taking into account their actual energy efficiency. The main research tasks are to analyze existing methods for assessing the financial efficiency of heat generating companies, as well as to develop a new method for assessing the investment attractiveness of heat generating companies, taking into account their actual energy efficiency. For the analysis of key fundamental financial indicators, three heat generating companies located in different regions of Russia and using different energy production cycles, as well as using different types of fuel have been selected. The methodology and research methods are based on a fundamental financial analysis of the indicators of heat generating companies. A comparative analysis of the profitability of three heat generating companies, as well as the average indicators for the industry, revealed the most inefficient company. For this company, an analysis of other financial indicators for the last ten reporting years has been performed. A comparative analysis of the specific fuel consumption for the generation of heat and electricity in these companies has also been performed. Based on the results of the results obtained, it is proposed for an objective investment assessment of heat generating companies to adjust their revenue and profitability, taking into account the indicators of their actual energy efficiency
USING THE TOOLS OF THE EXPERIENCE ECONOMY IN TOURISM
Authors:   Ural state University (national research UNIVERSITY), Chelyabinsk, Tarkhanovа N.
Published: December 2022

As a response to the ever-increasing number of suppliers and services, the concept of the impression economy has emerged. In tourist activity, this is extremely important, because it is not a product that is being sold, but impressions. They can be created, adjusted. Creating a positive experience is important for the return tourism business. The use of impression marketing elements will contribute to the sustainable development of tourism in a particular territory. The object of the study is tourist experiences. The subject of the study is the role of various components in the system of consumption of tourist products. The aim of the study is to identify the factors influencing the tourist experience formation as a result of the tourist products consumption. The objectives of the study are the following: to determine the significant factors that influence the formation of the consumer's impression of the visited territory; to identify the reasons that prevent the potential consumer to consider the territory as a possible holiday destination; to identify possible options to eliminate the problems associated with negative impressions. The article provides an overview of the main areas of research in the field of impression economics, including in the tourism industry. The authors aimed to identify the factors influencing the formation of a tourist impression as a result of the consumption of tourist products. An attempt is made to determine the most significant factors from the consumer's point of view that form positive impressions of the visited territory, identify the reasons that prevent a potential consumer from considering the territory as a possible place of rest or re-visit and identify ways to eliminate the negative impression. The authors have chosen a method of questioning consumers of tourist services. During the survey, it was found out that the formation of impressions is influenced by the quality of attractions, not their quantity, involvement in events taking place on a particular territory, service at catering establishments, accommodation. For different types of recreation, the formation of positive emotions is different. Negative emotions are formed in all kinds of experiences (educational, aesthetic, entertaining, escapism). To neutralize the negative experience of tourists, it is necessary to take into account the tools of the impression economy in the promotion of tourist products, both at the level of individual travel agencies and administrations when developing a strategy for the development of tourism in their territories. This will create a basis for attracting tourists to the destination

The shipping industry is the primary and most significant mode of international cargo transportation. The ship must comply with strict rules regarding reducing greenhouse gas (GHG) emissions as a dominant transportation mode. Liquified Natural Gas (LNG) is the primary alternative fuel option for several shipping companies. In essence, many studies recommend LNG as a transitional and alternative fuel because its emission characteristics are cleaner than other fossil fuels. Several previous investigations have been carried out to develop an action plan for integrating the use of LNG as a ship fuel. However, there have been few discussions on the estimation of GHG emission reduction and the economic efficiency of a representative LNG-fuelled ship. The recent progress on LNG-fuelled ships is systematically reviewed to summarize the pathways and highlight the core technological concepts, technical issues, current LNG-fuelled ship applications, and future outlooks regarding integrating LNG energy resources into ship power systems to measure GHG emission reductions and cost savings estimations. The report will discuss the current development in the maritime sector and the effects of the macroeconomic scale. The result reveals that future research on ship-based LNG energy systems will probably concentrate on integrating new energy source generating strategies with existing ship power systems to improve energy efficiency. Several potential research areas for future outlook were also discussed to anticipate future challenges.
Two Cities Seen by Flâneur and Flâneuse: Benjamins’ Paris and Woolf’s London
Authors:   British And American Language And Literature Association Of Korea, Ha Sujeong
Published: December 2022

This paper explores how Walter Benjamin and Virginia Woolf reflected on metropolitan city life in early modern period as a flâneur and a flâneuse . In Arcades Project, Benjamin attempts to reassemble ‘thought images’ from former century’s historical fragments in Paris streets of the 1920s and the 1930s and make a new literary montage. As a flâneur, he observes the streets flooded with people and the products to get his insights on the consumerism of capitalist production. Virginia Woolf, on the other hand, describes in her essay “Street Haunting: A London Adventure” a flâneuse who comes to intuitively grasp the two faces of the metropolis where wealth and poverty coexist. In “The Docks of London,” she criticizes surging merchandises of New imperialist capitalism which are born and domesticated by relentless human desire. While street walking enables Benjamin to embody thought images, it gets Woolf to feel freedom as an imaginative individual being. Benjamin searches for the meaning of phantasmagoric ‘merchandises’ on Paris street, but Wolf glances deserted ‘lives of people’ veiled with glittering city lights.
Price convergence on the national gas markets of the Eastern European region
Authors: Bublyk Yevhen , Kurbet Oleksandra , Yukhymets Roman
Published: December 2022

Establishing institutional arrangements for regulating gas markets toward price convergence is one of the crucial integrational factors. The strategy of the firm and economic development management depends on it. The paper aims to assess the characteristics of price convergence on the natural gas markets of the Eastern European region. This region is relevant for Ukraine in a number of parameters. The assessment was made based on Eurostat data for different groups of consumers, excluding taxes, using the standard deviation detection method of price convergence for 15 countries in 2007–2020. Despite the revealed generally positive price convergence on the natural gas markets in the considered countries after 2014, obtained results showed three points that highlight the heterogeneous structure of the process. First, an even movement toward a single price is detected in groups of large households (the standard price deviation of the price decreased in 2014–2020 from 2.7 to 1.9 euro per Giga Joule or 1.5 times) and medium industrial enterprises (the standard deviation decreased from 1.0-1.7 to 0.6-1.1 or 1.5-1.8 times). Second, the prices for the largest industrial enterprises in considered countries approached the fastest (the deviation decreased from 2.0 to 0.5). Third, in the segment of small enterprises, the deviation even increased from 2.1 to 2.2 (1.05 times). This result highlights the gap in the institutional mechanisms of European integration and sources of uncertainty for the small firms’ management.

La crisis sociosanitaria es un gran desafío para la educación, pues requiere de un docente preparado para “aprender a aprender” dentro de un contexto de incertidumbre. Por ello, el presente estudio tiene como objetivo realizar un análisis descriptivo y propositivo del Aprendizaje Profesional Colaborativo (APC), como una estrategia sostenible y elemento dinamizador de la formación continua del docente en el marco de una educación de calidad. Para lo cual, se realizó una investigación cualitativa mediante entrevista semiestructurada a ocho expertos internacionales en educación, que fue procesada a través del software Atlas TI versión 7.5 en español y sometido a análisis de contenido temático. Los resultados revelaron tres categorías emergentes como son la investigación educativa sustentada en la colaboración intergeneracional, la resiliencia comunitaria intra e interinstitucional y las necesidades de desarrollo socioemocional para una colaboración eficaz. Se concluye la importancia del Aprendizaje Profesional Colaborativo como un medio sostenible para una mayor cualificación del docente en servicio, pues fomenta su capacidad de autoformación, reflexión e investigación, así como aprender a convivir y aprender a transformarse a sí mismo y a la sociedad.

Actualmente, la ciudadanía como concepto, se construye a la par de la expansión tecnológica y del internet, desde donde se han generado nuevas formas de interactuar y participar de los asuntos públicos. En este contexto, el concepto de Ciudadanía Digital surge para entender el comportamiento ciudadano en la esfera digital. El presente estudio, evalúa las propiedades psicométricas de la Escala de Ciudadanía Digital (ECD) (Choi et al., 2017), adaptada a su uso en México. La muestra estuvo conformada por 522 estudiantes universitarios/as entre 18 y 30 años, de los/as cuales el 64.5% fueron mujeres. Los métodos utilizados fueron análisis factoriales exploratorio y confirmatorio. Los resultados sugieren retener los 26 ítems en un modelo de 5 factores (χ2(289) = 998.71; CFI = .96; TLI = .97, RMSEA = .06, SRMR = .07) que explicó el 67% de la varianza y coincidió con la propuesta teórica, salvo por un cambio en relación a la pertenencia del ítem 6 al factor Acciones en Red. El análisis de fiabilidad indicó un alfa ordinal total de 0.92 y el análisis correlacional demostró evidencia de validez discriminante. Se concluyó que la ECD presenta adecuadas propiedades psicométricas para su uso en universitarios/as de México.
İkonografik, Mitolojik ve Dekoratif Olarak Kozalak Motifi ve Tekstil Sanatında Kullanımı
Authors: Aksoy Elif
Published: December 2022

Paleolitik dönemden beri mağara duvarlarına çizilen şekiller, zaman ilerledikçe sanat eserlerinde görülmeye başlamışlar ve sembolizmin taşıyıcı rolünü üstlenmişlerdir. Dolayısıyla sembol, her nerede doğarsa doğsun, içinde bulunduğu dönemin; toplumunu, kültürünü ve coğrafyasını yansıtmakta ve bunlara göre şekil almaktadır. Semboller, ikonografik olarak çözümlenirken, doğmuş oldukları toplumların; mitolojileri, efsaneleri, inançları, ritüelleri ve geleneklerinden etkilenirler. Eski zamanlardan beri birçok sanat eserinde bir sembol olarak görülen kozalak, çeşitli hastalıklar için halk hekimliğinde bir şifa aracı olarak kullanılmıştır. Antik medeniyetlerin sanat eserlerinde ve mitlerinde hem dini bir öge, hem de mitolojik bir simge olarak yer alan bu sembol, tekstil sanatında da dekoratif bir motif olarak karşımıza çıkmaktadır. Bu makalede, kozalak motifinin, antik zamanlardan beri çeşitli kültürlerdeki yeri literatürden elde edilen veriler ışığında ikonografik ve mitolojik olarak analiz edilerek yeniden düzenlenecek ve tekstil sanatında nasıl kullanıldığı belirlenecektir.

Sanatta Şeffaflığın Temsili
Authors: Arığ Tanzer
Published: December 2022

Bir çok farklı disiplinin ele aldığı bir kavram olarak şeffaflık, en genel tanımıyla saydam, içerisinden ışığın geçmesine engel olmayan, arkada kalanı görünür kılan olarak öncelikle fiziki özellikleri üzerinden tanımlanırken, mecazi anlamda da bilgiye koşulsuz bir şekilde ulaşılabilen, tüm eylemlerin açık ve kontrol edilebilir olduğu bir tanımlamaya karşılık gelmektedir. İster fiziksel özellikleri, isterse mecazi anlamı üzerinden ele alınsın her iki tanımlamadan da anlaşılacağı üzere şeffaflık kavramının temelde gizli olmayan, belirgin olanı açıkça ortaya koyan bir temsile karşılık geldiği görülmektedir. Bu araştırma, şeffaflık kavramının sanat alanı kapsamında sınırlandırıldığı, dönemsel koşullara ve sanatçıların eğilimlerine bağlı olarak biçimsel ve kavramsal açıdan nasıl ele alındığı ve farklı yorumlandığı üzerine gerçekleştirilmiş bir incelemedir.

Published: December 2022

Safety is an integral component of everyone’s life. However, this concept remains elusive to comprehensive linguistic research. The present article focuses on the concept of safety as one of the most important ideas for modern humanity. The authors believe that this research helps to cast light upon some social processes that are reflected in language. During an uncontrolled associative experiment, Russian and German respondents gave verbal reactions to words besopasnost (safety) and Sicherheit. The content and subject of reactions were not limited. The purpose of the research was to identify the associative meanings of these concepts in each of the languages. The article presents the most frequent and typical verbal reactions, as well as their comparative analysis and semantic classification. Both German and Russian respondents shared such meanings as protection / means of protection, home / housing , internal qualities / feelings of security. Only Russians respondents gave such reactions as calmness / peace, comfort; only German respondents mentioned power / public institutions and money / finance.
Human Sensorimotor Activity as a Factor of Cognitive Resource Development
Authors: Balanev D. Yu. , Tyutyunnikov P. R. , Kokh D. A.
Published: December 2022

The cognitive resource phenomenon, its factors, and performance are a relevant topic of Russian psychology. Numerous publications feature the psychological content of the cognitive resource concept and various phenomena as forms of its manifestation. However, domestic psychology sees no cognitive resource potential in sensorimotor activity, nor does it see sensorimotor activity as a factor that facilitates human cognitive resources. The article considers sensorimotor activity as a cognitive resource and describes a transspective analysis of various approaches to the phenomenon of cognitive resource. The authors defined the latter as a complex multi-level construct. Various cognitive resource models proved that sensorimotor activity is a manifestation of the cognitive resource and its integral part. However, the transspective analysis requires further research on sensorimotor activity in the cognitive resource structure.
Coping in Times of Uncertainty and Global Risks: The Main Research Trends
Authors: Belinskaya E. P.
Published: December 2022

This article reviews foreign and domestic publications on the psychology of coping. Until the early XXI century, coping studies followed three research lines: 1) situations perceived as "difficult", 2) coping strategies and/or styles, 3) their relationships with personal and environmental coping resources. The current global situation of uncertainty and risks has affected the strategy of coping studies. They now demonstrate a more complex and holistic vision of the interaction between the person and the situation that requires coping. The interaction pattern follows three main research trends: 1) Personal coping resources are understood not as specific personal dispositions or cognitive characteristics, but as complex features that require new research methods; 2) New empirical material proves the ambiguity of correlation between various human coping strategies and psychological well-being; 3) Procedural features of coping and its anticipatory capabilities acquire more scientific attention.
