Revisiting Flavell’s Theory of Metacognition for Metacognitive Responsiveness
Authors: Ozturk Nesrin
Published: April 2024

The theory of metacognition was innovative at the time for its promising practicality. However, research findings that pertain to inconsistencies in metacognitive trainings’ outcomes and mainstream classrooms’ adversities of metacognition practices have accumulated since then. These issues may highlight a need to revise metacognition theory. From a phenomenological perspective, this paper first describes the fundamental tenant of theory; thinking and whether thinking about thinking recognizes the nature of thinking. For individuals to manage their thinking, thinking should be stimulated first. Metacognitive responsiveness pertains to a conscious sensitivity towards a stimulus that might engage one into higher order thinking. Metacognitive responsiveness, thereby, may initiate attendance of attending higher order thinking in recognition of a stimulus. Thinking and metacognitive responsiveness pertain to personal relevance, attentiveness, interest, previous experiences, tools for thinking, features of tasks, and the nature of social interactions. In this sense, the stimulus should be designed or adapted to initiate each individual’s thinking or metacognitive responsiveness. This paper argues that the theory of metacognition needs a revision to embrace metacognitive responsiveness explicitly, and practical implications need to focus on materials to initiate metacognitive responsiveness for metacognitive development.
A Program Evaluation Study for Measurement and Evaluation Course in Distance Education
Authors: Akıncı Muhammed , Köse Erdoğan
Published: April 2024

This study aims to evaluate the online measurement and evaluation course in teacher training programs during the COVID-19 process. In the study, we sought answers to two primary research questions: What are the opinions of teachers and school administrators regarding their measurement and evaluation competencies? Does the online "measurement and evaluation" course have the qualities of an effective program in the "antecedents, transactions, and outcomes" dimension? We structured the research into two phases within a multistage evaluation design framework. The findings show that there were problems and positive aspects in all dimensions of the program. For example, adapting teacher training programs developed before COVID-19 to distance education processes was challenging. In distance education, some practices contradict the modern teaching and assessment approach. Such problems were reflected in teachers' acquisition of measurement and evaluation competencies. The achievement test we applied to the observed groups also confirmed these findings. For this reason, responsible organizations should not ignore the fact that we cannot renounce distance education. During program development, they should reconsider how the teachers will acquire measurement and evaluation competencies and how we will measure and evaluate in distance education.

The Exploring the Relationship between Financial Performance Indicators, ESG, and Stock Price Returns: A Rough Set-based Bipolar Approach
Authors:   Department of Banking and Finance, Chinese Culture University, Taipei, Taiwan, Shen Kao Yi
Published: April 2024

Using a Rough-Set-based approach, this study investigates the connection between financial performance, Environmental, Social, and Governance (ESG) factors, and stock returns. It analyzes data from various companies and industries to examine how ESG metrics interact with financial indicators to influence stock prices. Those findings underscore the importance of considering financial and ESG factors when evaluating a company's performance and market valuation. The Rough-Set-based bipolar model comprises eight decision rules, and the DEMATEL (Decision-Making Trial and Evaluation Laboratory) analysis reveals the influence relationship among the core attributes. Furthermore, the ranking result, based on the bipolar model, is consistent with the market returns, which suggests the validity of this study.

Mathematized Phenomenology and the Science of Consciousness
Authors: Prentner Robert
Published: April 2024

In this contribution, we emphasize the relevance of mathematical approaches to the first-person perspective. We briefly discuss why this is necessary and why mathematics plays a special role when it comes to integrating scientific (empirical) and philosophical (theoretical) projects. We also sketch some potential ways that mathematics could be used in phenomenology, based on a selection of four ``phenomenological primitives'' that characterize constitution: intentionality, minimal subjectivity, lifeworld, and time consciousness. We also spell out a minimal topological toymodel and refer to some contemporary approaches using modern mathematics (e.g. category theory). We then discuss how this could be usefully applied to the (neuro)scientific study of consciousness and throughout stress the need to highlight (and formalize) phenomenology's transcendental character.
Modality and Stimulus Effects on Distributional Statistical Learning: Sound vs. Sight, Time vs. Space
Authors: Zhou Haoyu , van der Ham Sabine , de Boer Bart , Bogaerts Louisa , Raviv Limor
Published: April 2024

Statistical learning (SL) is postulated to play an important role in the process of language acquisition as well as in other cognitive functions. It was found to enable learning of various types of statistical patterns across different sensory modalities. However, few studies have distinguished distributional SL (DSL) from sequential and spatial SL or examined DSL across modalities using comparable tasks. Considering the relevance of such findings to the nature of SL, the current study investigated the modality- and stimulus-specificity of DSL. Using a within-subject design we compared DSL performance in auditory and visual modalities. For each sensory modality, two stimulus types were used: linguistic versus non-linguistic auditory stimuli and temporal versus spatial visual stimuli. In each condition, participants were exposed to stimuli that varied in their length as they were drawn from two categories (short versus long). DSL was assessed using a categorization task and a production task. Results showed that learners' performance was only correlated for tasks in the same sensory modality. Moreover, participants were better at categorizing the temporal signals in the auditory conditions than in the visual condition, where in turn an advantage of the spatial condition was observed. In the production task participants exaggerated signal length more for linguistic signals than non-linguistic signals. Together, these findings suggest that DSL is modality- and stimulus-sensitive.
How the content and form of parent-child conversations about race relate to the development of racial attitudes
Authors: Britton Tobias C. , Rizzo Michael , Brenner Jonah , Gordon Aislyn , Rhodes Marjorie
Published: April 2024

The present study investigated how parent-child conversations about race relate to children’s racial attitudes. Conversations were collected remotely from 124 children (ages 4-8; 16% Asian, 20% Black, 13% multiracial, 14% Latino/a, 35% White, 2% unspecified; 57% female, 42% male, 1% other) and their parents from across the United States. Parents’ beliefs about race predicted aspects of conversational content (e.g., acknowledgement of racial injustice) and linguistic form (e.g., generic claims), and families who produced a higher proportion of generic references to race had children who demonstrated more anti-Black attitudes. These results illustrate the importance of examining natural language to provide a comprehensive picture of the form and content of parent-child conversations about race.
Offshoring insect farms may jeopardise Europe's food sovereignty
Authors: Ryba Ren
Published: April 2024

In the context of the Russian invasion of Ukraine and increasing global destabilisation, policy makers within the European Union have expressed the need to reduce the bloc's dependence on imported agricultural products such as livestock feed. One industry that has been promoted as an advantageous source of livestock feed is the insect farming industry. However, the insect industry's growth has not kept pace with optimistic expectations, and high labour and electricity costs in Europe appear to be driving major insect companies to expand production offshore. Solutions may include supporting the automation of insect farming, though automation may have harmful social consequences, or bringing additional land under cultivation to expand domestic production of maize and soy.
Zur Beschäftigungssituation im Mittelbau an der Universität Wien: Ergebnisse der Befragung
Authors: Partheymüller Julia , Dannecker Petra
Published: April 2024

Im Oktober 2021 trat die Novelle des Universitätsgesetzes in Kraft, die unter anderem Kettenverträge für das wissenschaftliche Personal neu regelte (§ 109). Dies führte zu einer Vielzahl von Problemen, insbesondere für befristete Mitarbeiter*innen, und löste eine öffentliche Diskussion über Arbeitsverhältnisse an österreichischen Universitäten aus. Um einen Überblick über die Beschäftigungssituation des Mittelbaus zu gewinnen und eine Evidenzbasis zu schaffen, führte eine Arbeitsgruppe an der Fakultät für Sozialwissenschaften von Dezember 2022 bis Jänner 2023 eine Befragung des akademischen Mittelbaus an der Universität Wien durch (N=1.102). Die Ergebnisse zeigen eine geringe Kenntnis der rechtlichen Rahmenbedingungen, eine weitreichende Betroffenheit aufgrund komplexer Erwerbsbiografien und vielfältige negative Auswirkungen auf die Beschäftigten, darunter insbesondere berufliche Unsicherheit und psychische Belastungen. Die Aussichten auf Festanstellung sind insgesamt äußerst gering. Zudem dokumentieren die Ergebnisse mittelbare negative Folgen für Forschung, Lehre und die Universität als Institution. Auf Grundlage dieser Ergebnisse werden kurz- und langfristige Handlungsempfehlungen abgeleitet, um die Rechtssicherheit und Planungssicherheit für die Beschäftigten zu erhöhen.
Hindu Patriarchal Society and the Rise of Modern Female Characters: A Contextual Reading of Selected Modern Nepali Plays
Authors: Rijal Shiva
Published: April 2024

This paper explores the way the first-generation modern Nepali playwrights Balkrishna Sama (1903-1981), Bimnidhi Tiwari (1911-973) and Vijay Malla (1925-1999) responded to the existing values of the Hindu patriarchal society by creating female characters. It mainly focuses on Indira from Mukunda Indira (1939) by Sama, Sushila from Sahanshila Sushila (1940) by Tiwari and Urmila, and Pratima from Jiundo Las (1955) by Malla. With the insights taken from Western feminism, mainly the ideas of Judith Butler that gender is ‘scripted’, the paper interprets these female characters by contextualizing the plays in Nepal’s social history. It concludes that Urmila and Pratima represent the pain and suffocation of the first-generation educated female youths of the nation who were yet to recognize the harm its patriarchal values have done to its female members. Indira and Sushila are comparatively docile and do not feel the need to break the grand scripts. Malla by projecting the pain and frustration of female characters who live psychologically complex lives shares the message of the urgency of addressing women’s issues with his audiences.

Relationship between grass height, grazing management and avifauna in livestock systems in the eastern region of Uruguay
Authors: Aldabe Toribio Joaquín , Blumetto Oscar
Published: April 2024

In the natural grasslands of the Río de la Plata, where livestock production can coexist with biodiversity, effective pasture management practices play a critical role. This study combines two approaches to shed light on the relationship between livestock management and bird species. The first study analyzes birds' responses to various variables influenced by livestock management. Field data were collected and 69 bird species were analyzed across 454 paddocks on 46 properties in the eastern region of Uruguay. We found that artificial grasslands had a negative impact on many bird species, while the presence of tussock patches (grasslands) was associated with positive effects, especially in endangered species. Grassland specialists exhibited sensitivity to grass height, responding positively to tussock patches but negatively to tree coverage. Adjusting livestock stocking rates to control grass height emerges as a valuable tool to promote grassland specialists. The ideal scenario for bird biodiversity involves a mosaic of native grasslands, both short and tall, interspersed with tussock patches and trees. Additionally, we found that species-specific responses were influenced by bird traits, such as body size and foraging behavior, enhancing predictive capacity for pasture management. The second study focused on assessing bird responses to changes in management on six properties to increase grass height, thereby improving dry matter intake by livestock and potentially increasing livestock production. Although the average grass height increased from 6 cm to 12 cm, bird abundances and species richness did not vary. However, since the abundances of the assessed species remained constant with increasing grass height (and thus, available dry matter for livestock), we conclude that it is possible to protect a subset of grassland specialist birds while potentially increasing livestock production.
Ramularia leaf spot management alternatives in barley optimizing the use of fungicides for its control
Authors: Palladino Almada María Cintia , Pereyra Silvia , Pérez Carlos Alberto
Published: April 2024

Ramularia collo-cygni (Rcc) is the causal agent of Ramularia leaf spot (RLS). The main management tool is the use of foliar fungicides, the impact of which on cereal safety is unknown. Therefore, the aim of this thesis was to optimise the management of ramulariosis in barley and to minimise fungicide residues in grain. The specific objectives were: (i) to validate a method for the detection and quantification of Rcc in seeds and seedlings by real-time PCR (qPCR), (ii) to determine the importance of seeds as a source of in-crop Rcc inoculum in production systems in Uruguay, (iii) to develop a methodology to determine the fungicides proposed for the control of rhamulariosis in barley grain, and (iv) to identify foliar fungicide application strategies to minimise rhamulariosis and ensure fungicide safety in the grain produced. The qPCR technique was validated for the detection and quantification of Rcc in barley seeds and seedlings. This qPCR technique will allow the optimal timing of foliar fungicide applications to be determined by detecting Rcc in seedlings. The amount of Rcc DNA in commercial lots varied within and between growing seasons, highlighting the importance of this tool for quantifying fungal load prior to sowing. A method was developed to quantify fungicide residues in barley grain. This method was extended to quantify fungicides in wheat grain and mycotoxins produced by the Fusarium species. This analytical methodology could be useful for monitoring compliance with maximum residue limits (MRLs) in winter cereal production. Foliar fungicide strategies for the control of RLS were evaluated in five trials over three consecutive years. The efficacy of fungicides in controlling the disease and ensuring grain safety was tested with fungicide residue levels below MRLs. The results contribute to the management of RLS with tools to reduce fungicide use and ensure barley grain safety.
Imperial Responses to the Food Crisis that Began under Claudius
Authors: Graham Daryn
Published: April 2024

The main focus of this article is the nature of imperial responses—symbolic and practical—to the major food crisis in Rome throughout the principates of Claudius and Nero. By examining the evidence through a historical lens, it will be demonstrated that when real food crises became serious, concerted attempts were made by Claudius and Nero to address starvation concerns and feed the city of Rome, and in some ways elsewhere. The result was a range of special building projects whose nature was to provide employment, as well as promote trade, and individual identity. The first and foremost of these projects was Portus harbour.
“This Is My House!”: Producing and Protecting Intimacy in the Platformed Cancer Community
Authors: O’Meara Victoria , Hodson Jaigris
Published: April 2024

Based upon a series of in-depth, semi-structured interviews with popular cancer influencers, this paper examines the practices by which intimacy is co-produced and managed in the online cancer community. Drawing theoretically from feminist theory, affect theory and cultural studies, the authors explore the complex boundary work that cancer survivors and caregivers engage in to establish, sustain, and protect themselves as an intimate public. The findings show that outsiders, difference, and the threat such things pose to community harmony are actively operationalized to sustain intimacy among cancer community insiders. In the discussion, the authors reflect on what these findings suggest about the politics, possibilities, and limits of platform-mediated forms of intimacy.
IDENTIFICATION OF THE BOTANICAL ORIGIN AND DETERMINATION OF PHYSICOCHEMICAL PARAMETERS OF HONEY SAMPLES COLLECTED FROM THE SARY-CHELEK BIOSPHERE RESERVE OF KYRGYZSTAN
Authors: Ishenbaeva Nazgül , Musulmanova Mukarama , Smanalıeva Jamila
Published: April 2024

Sary-Chelek Biosphere Reserve is one of the richest rare flora and animal reserves in Kyrgyzstan. The natural environment of the Sary-Chelek Biosphere Reserve is exceptionally favourable to high-quality honey production. Botanical authenticity is the main factor influencing honey prices, as it has a direct impact on the quality of honey. Producing monofloral honey in a natural landscape is challenging because, throughout the beekeeping season, multiple melliferous plants bloom at the same time. The article describes for the first time the botanical origin and physicochemical characteristics of honey collected in this biosphere reserve and also determines the influence of the dominant honey plant on organoleptic, physicochemical, and food safety indicators. Pollen grains of 50 taxa of nectar sources and about 10 taxa of pollen sources were identified. There were unique plant pollens in the samples; nine of the samples were monofloral honey—three of sage (Salvia officinalis L.), four of thyme (Thymus vulgaris L.), and two of eremurus (Eremurus fuscus O.Fedtsch), and eight samples were polyfloral honey. High diastase activity was found in samples of thyme honey (41.1 ± 2.9 Gothe) and in samples of sage honey (31.3 ± 2.2 Gothe). The physicochemical and food safety parameters of the honey samples comply with the established norms and international standards.
The Ethnic Content of the Values Son and Daughter in the Kazakh Culture: Ethnopsycholinguistic Study of Family and Relative Values
Authors: Kuzembayeva Gulzhana
Published: April 2024

Purpose. The study is aimed at exploring the ethnic content of values ұл / son and қыз / daughter in the Kazakh language and culture bearers’ linguistic consciousness and determining their place in the system of family and relative values in the Kazakh culture at the level of the state. The problem under study is especially relevant in the context of transformation of Kazakhstani society, heterogeneity of language situation and cultural diversity across regions.

Methods. The study employed an ethnographic research design, which included a component analysis, an association experiment, and a ranking of values ұл / son and қыз / daughter by the representatives of the Kazakh nation. The study materials comprised linguistic data, obtained from dictionaries and encyclopedias of the Kazakh language, Kazakh paremias, and data of the association experiment. Semantic components of the values were defined and modelling of the association fields was conducted with further categorization of semantic gestalts.

Results. The analysis of Kazakh dictionaries, encyclopedias and paremias revealed the importance of raising children based on good examples in Kazakh families. A son in Kazakh culture is considered great happiness, luck, and wealth, as he is the successor of his father and the heir of the family house in the future, whereas a daughter is raised in especially strict conditions, though treated as a guest, considered the prosperity in the family, pampered and valued for her beauty and girlish behaviour. The association experiment’s results were in line with the analysis of proverbs, showing the common and different components in the association fields and semantic zones of the values. The ranking of values ұл / son and қыз / daughter confirmed our hypothesis.

Conclusions. Children are of utmost importance in the Kazakh culture, though the treatment and relation to a son and a daughter, as well as their place in the family differs because of their different roles and responsibilities.

INTENSIFICATION OF HEAT AND MASS EXCHANGE PROCESSES OF PROCESSING OLD SLUDGE
Authors: Petrova Zh. , Novikova Yu. , Petrov A.
Published: April 2024

At sewage treatment plants, in addition to filtered water, sludge is formed during wastewater treatment. They are dumped on mud sites, which occupy large areas and are almost completely overflowing. The content of a large amount of minerals and toxic substances in sediments leads to the deterioration of the condition of groundwater and soil, which in turn leads to the deterioration of ecology and life. An urgent task in Ukraine is the creation of complex processing of sludge, which includes economic, technological, social and ecological aspects.

The purpose of the research is to intensify the heat and mass exchange processes of processing old sludge deposits with the subsequent creation of a technology for obtaining composite fuel based on them.

The study of drying kinetics of composite granules was carried out on an experimental convective stand with automatic data collection. A comparison of the drying time of composite granules depending on the granulation method was carried out, which showed the expediency of carrying out the process for granules formed on a screw mechanical device. Adsorption studies were carried out, which made it possible to determine the equilibrium moisture content. It was established that the specific heat of combustion of composite granules exceeds the heat of combustion of peat by 1.2 times, which allows them to be used as an alternative fuel.
FINDING THE RELATIVE TRAJECTORY OF THE CARGO IN THE BODY OF A VEHICLE WHICH IS GOING DOWN OR UP ON A CURVED SECTION OF THE ROAD
Authors: Pylypaka S. F. , Nesvidomin A. V.
Published: April 2024

With a certain assumption, the load, which during relative movement along the bottom of the body makes translational movement, can be taken as a material point. In this case, finding the relative movement of the load in the body when the car moves along the road with a spatial axis is reduced to finding the relative trajectory of the material point.

In known works, it is proposed to use the accompanying trihedron of the trajectory of the transfer motion and Frenet's formula to find the absolute acceleration vector of a point. The independent variable is not time, as in traditional problems, but the arc coordinate of the transfer trajectory, since only under this condition can Frenet's formulas be applied. The vector of absolute acceleration is obtained in projections onto the vertices of the moving accompanying trihedron, without looking for individual components (transfer, relative, and Coriolis acceleration), as is done in traditional approaches.

The purpose of the study is to investigate the relative movement of the load, taken as a material point, along the bottom of the body of a truck moving along a curvilinear section of the road with a spatial axis during its ascent or descent.

The spatial curve is characterized by two parameters that depend on the kinematics of the accompanying Frenet trihedron. These parameters are the curvature k and the twist σ of the curve. Their values at any point of the curve will be determined if the dependencies k=k(s) and σ=σ(s) are known, where s is the arc coordinate (the arc length of the curve). It is assumed that such a spatial curve is the axis of a curved section of the road that goes uphill or downhill.

The application of the accompanying trihedron of the curve and Frenet's formulas made it possible to describe the relative motion of the cargo in the body of a car moving along a road having a spatial axis with constant and variable speeds. The regularities of the relative movement of the cargo when the car is moving on the road, the axis of which is a helical line with constant curvature and twist, have been found. It was found that there is no significant difference between the value of the relative speed of the cargo when the car moves at a constant speed down or uphill at the initial stage. When braking on a descent, a significant relative movement of the cargo is observed, which increases with an increase in the braking acceleration, and when climbing, on the contrary, the relative movement decreases with an increase in the braking acceleration. The regularity of the relative movement of the cargo when the car moves along the road with variable curvature and torsion of the axis line depends on the type of these dependencies as a function of the length of the arc of the axis line.
Recovery of Velykyi Luh through ecological restoration of the Kakhovka Reservoir
Authors: Dzyba Аnzhela , Kyriienko Volodymyr
Published: April 2024

The relevance of modern environmental issues requires comprehensive approaches to the restoration and preservation of natural ecosystems, specifically through ecological restoration as a tool to eliminate the effects of anthropogenic interventions. The purpose of this study was to survey the territory of the Kakhovka Reservoir using remote sensing and to propose a way to restore the historical territory of the Kakhovka Reservoir of Velykyi Luh. The following research methods were employed: empirical, analysis and systematisation, remote sensing, geographic information systems. The study consisted of two main stages. The first stage included an analysis of the dynamics of the historical territory of Veliky Luh, from the end of the 19th century to the present day. The second stage involved comparing the dynamics of the area’s restoration using 19th-century mapping data and 21st-century satellite imagery. The use of modern technologies, including the analysis of satellite images of the degraded area and three indices of the EO Browser software, such as the differential vegetation index, the normalised differential humidity index, and the differential water index, helped to obtain data on the state of vegetation and water resources in the study area. The analysis of the patterns between these indicators made it possible to determine the close interaction between plant growth rates and their moisture availability. The biomass growth on the territory of the Kakhovka Reservoir was measured from the moment of dewatering to November 2023. The results obtained indicate that it is possible to effectively restore the ecosystem of the Velykyi Luh through ecological restoration. This process involves the selection of optimal biotopes for the restoration of the historic area, which is a crucial step in conserving biodiversity and stabilising the natural environment in the Kakhovka Reservoir. The findings of the study on a new approach to ecological restoration based on high-precision technologies and in-depth analysis of ecosystem dynamics will contribute to the development of scientific approaches to the restoration of natural landscapes and will be an important contribution to modern environmental practice
Formation of productivity of maize hybrids of different ripening groups in the Forest-Steppe region
Authors: Mokrienko Volodymyr , Kornienko Taras
Published: April 2024

The relevance of the study is determined by the necessity of scientifically substantiating the rational ratio of maize hybrids of different ripening groups to ensure the realisation of the genetic potential in forming pre-harvest grain moisture at the level of 18-22%. Therefore, the purpose of the study is to identify the most adapted and plastic ripening groups considering biological features and to identify stable hybrids based on economic efficiency through the calculation of the hybrid’s productivity efficiency index. The method of plot division was used to conduct field research in accordance with the requirements of the research methodology. The results revealed that maize hybrids of different ripening groups react differently to temperature conditions, especially during the interphase period – 3-5 leaves. Maize hybrids with FAO (ripening group of the hybrid) 180-250, having a flint grain subtype, are characterised by faster linear plant growth due to higher cold resistance, making them suitable for early sowing when the soil temperature is 6-80C. Hybrids with FAO 300 and above, with a dent grain subtype, exhibit slower initial plant growth and are more thermophilic. Therefore, it is advisable to plant them after the soil has been thoroughly warmed to 8-100C. Studies have established that the highest grain yield was obtained from mid-late maturity maize hybrids (FAO 401-500) – 10.04-10.17 t/ha, with a maximum level of 14.89 t/ha in 2017. However, considering the dynamics of productivity levels over the years, the most plastic hybrids, i.e., those with the smallest difference in yield between years, are phenotypes with FAO 201-300. It was determined that early and mid-early ripening group hybrids had lower pre-harvest grain moisture – 0.6-23.9% compared to 28.7-2.7% in mid-ripening and mid-late ripening groups. This resulted in a higher productivity efficiency index for these hybrids. The materials of the study contain results for further research on optimising the use of maize hybrids with different FAO numbers and are of practical significance for farms of various ownership forms

Published: April 2024

The world is shifting from conventional, time-consuming ways of transaction to the world of mobile phones where they can make all their transactions with easy access, cost-effective, and sustainable ways. In Pakistan after 2008 state banks regularized branchless banking. The purpose of this study is to analyze the trend of mobile money in the last six years’ time period. The research uses quarterly data from 2015-2020 related to factors impacting mobile financial inclusion in Pakistan like mobile wallet transactions, over the counter transactions, total transaction value and volume, average daily transactions, mobile money accounts and usage segmented by gender, active accounts, agent data, and deposit amounts. We have analyzed that the trend of mobile money has increased in the last six years’ time period. The volume of mobile money in different provinces of Pakistan and Pakistan as a whole is increased. On the other hand, both males and females have an active role in financial inclusion. Though the ratio of the female is relatively low as compared to the men but overall, both have a significant role towards mobile money.

The authors longitudinally tracked images of a partially thrombosed anterior communicating artery aneurysm’s neck remnant, which had been treated with stent-assisted coil embolization, using silent MRA over a decade. Computational fluid dynamics delineated the neck remnant’s reduction process, evaluating hemodynamic parameters such as flow rate, wall shear stress magnitude and vector, and streamlines. The neck remnant exhibited diminishing surface area, volume, neck size, dome depth, and aspect ratio. Its reduction correlated with a decline in the flow rate ratio of the remnant dome to the inflow parent artery. Analysis delineated regions within the contracting neck remnant characterized by consistently low average wall shear stress magnitude and variation, accompanied by notable variations in wall shear stress vector directionality.

LESSONS

Evaluation of neck remnants after stent-coil embolization is possible through silent MRA and computational fluid dynamics. Predicting the neck remnant reduction may be achievable through hemodynamic parameter analysis.

BACKGROUND

Thoracic spinal cord injury after posterior cranial fossa surgery in younger patients is a rare complication. There have been reports of this complication in tumor and spine fields but not in vascular surgery.

OBSERVATIONS

A 22-year-old-man experienced cerebellar arteriovenous malformation rupture, and the malformation was surgically removed with the man in the Concorde position. After surgery, the man had severe paraplegia, and a thoracic spinal cord injury was diagnosed.

LESSONS

In younger patients, cervical hyperflexion in the Concorde position can cause thoracic spinal cord injury even in surgery for cerebrovascular disease.
Genel Popülâsyonda Obsesif Kompulsif Semptomların Yordayıcısı Olarak COVID-19 Stresi ve Bu İlişkide Duygu Düzenleme Güçlüğü, Obsesif İnançlar ve Tiksinmenin Aracı Rollerinin Değerlendirilmesi

COVID-19 salgını, başta birincil enfeksiyon riski ve küresel, sosyal ve ekonomik yönden yol açtığı ikincil sonuçlar bağlamında önemli bir stresördür ve bu yönüyle de psikolojik sağlık üzerinde önemli bir etkiye sahiptir. Buradan hareketle mevcut çalışmada, pandemi döneminde katılımcıların stres düzeylerinin incelenmesi, pandemik stres ile obsesif kompulsif semptomlar arasındaki ilişkinin değerlendirilmesi ve bu ilişkide duygu düzenleme güçlüğü, obsesif inançlar ve tiksinmenin rollerinin bir model kapsamında test edilmesi amaçlanmaktadır. Araştırmaya pandemi döneminde Türkiye’de ikamet eden; 18-65 yaş aralığındaki toplam 320 kişi (X=33.78, min=18; max=62) katılmıştır. Katılımcılara, COVID-19 Stres Ölçeği, Duygu Düzenleme Güçlüğü Ölçeği-Kısa Form, Obsesif İnanışlar Ölçeği, Tiksinti Yatkınlığı ve Duyarlılığı Ölçeği ve Vancouver Obsesif Kompulsif Envanteri uygulanmıştır. Analizler sonucu katılımcıların pandemiye ilişkin stres düzeyleri ile obsesif kompulsif semptomlarının orta ile yüksek düzeyde değişebildiği belirlenmiştir. Ayrıca pandemi stresinin obsesif kompulsif semptomlar ile ilişkili olduğu, mevcut ilişkide duygu düzenleme güçlüğü, obsesif inançlar ve tiksinmenin aracı rolünün bulunduğu belirlenmiş ve bu sayede semptomların gelişimine ilişkin önerilen yapısal model doğrulanmıştır. Elde edilen sonuçlar pandemi endişelerinin OKB açısından bir risk faktörü olabileceğini göstermektedir. Ayrıca bu ilişki örüntüsüne etki eden bilişsel ve duygusal birçok faktör de mevcuttur. Bu açıdan tedavi süreçlerinde mevcut faktörleri hedefleyen müdahalelerin geliştirilmesi semptomların klinik düzeye ilerlemesinin önlenebilmesi adına önemli girişimler olabilir.

This article investigates the properties of small-scale fluctuations of the probability density formeasurements of the X, Y, and Z-components of the Earth’s magnetic field that were carried out both in aseismically active region and in an area with a complete absence of seismic activity. In the first case, a muchgreater intensity of the occurrence of statistical phenomena considered as earthquake precursors was revealed.At an interval of several days before the earthquake with a magnitude of 5.3 in Metsavan (Armenia), whoseepicenter was located near the magnetic variation station in a seismically active region, a sharp increase in thefrequency of these phenomena was found. This effect was absent in the seismically quiet region
Features of the Behavior of SE-Type Radiation during a Substorm

Published: April 2024

A study was made of simultaneous observations of ultra-low-frequency oscillations in the 0.1–5.0 Hz frequency range of the serpentine emissions type (Serpentine Emissions, SE) observed at the polar capregion and disturbances in the auroral zone. The unique analog magnetic records of the Vostok AntarcticObservatory (corrected geomagnetic coordinates Φ' = –85.41°, Λ' = 69.01°) have been digitized with a highfrequency (20 Hz) and are freely available on the website of the World Data Center for Solar-Terrestrial Physics,Moscow. For 1966 (November and December), 1968 (March–July), and 1970–1972, 1973 (January–March) the behavior of “serpentine emissions” was analyzed during the development of 180 isolated substormsidentified by variation in AL indexes. An interruption in the mode of generation of serpentine emissionsin the region of the polar cap was found during the active phase of intense isolated substorms (with amaximum magnitude of the AE index of ∼500–600 nT). During the expansion phase of the substorms, broadbandnoise electromagnetic radiation appears with a sharp leading edge in the PC1–2 range and is alsorecorded in the polar cap. Noise radiation has a sharp leading edge and occurs approximately 2 hours afterreorientation of the bz-components of the interplanetary magnetic field (IMF) from north to south. The timeof the interruption of SE coincides with the beginning this radiation and moment of achievement bz-componentof maximum negative IMF values. Interruption of the SE effect is observed against the background ofrelatively stable other geoeffective parameters of the solar wind and IMF. The average duration of the interruptionof emissions is ∼3 hours. Indirect confirmation of the impact of substorm activity on the SE generationregime is found in the coincidence of the patterns of daily and seasonal variation of SE interruption intervalsand the probability of observing substorms. Due to the fact that noise emission occurs during the activephase of isolated substorms and ∼2 hours after reorientation of the bz-components of the IMF in the solarwind, there is reason to believe that it is associated with plasma flows directed towards the Earth from themagnetotail. Apparently, the energy of plasma flows during the active phase of a substorm stimulates theappearance of noise radiation, thus interrupting SE.

The results of analysis of measurements of the amplitudes and phases of the GQD (19.6 kHz) andGBZ (22.1 kHz) VLF transmitter signals at the Mikhnevo IGD observatory are presented to estimate of theinfluence of the solar flares X 2.2 and X 1.5 on June 10, 2014 on the electron concentration in the lower ionosphere.The flux of the X-rays in the more rigid spectral ranges of 0.01‒0.3, 0.01‒0.26, and 0.01‒0.22 nmwas calculated based on the measurements of the X-ray emissions at wavelengths of 0.05–0.4 nm and 0.1–0.8 nm at the GOES satellite. That allowed us to find the ionization rate and the emission spectrum rangesthat influenced the electron concentration dynamics most strongly. It is shown that if the duration of the forefrontis substantially less than the characteristic recombination time, the change in the electron concentrationprofile in the lower ionosphere on the flare front is related linearly to the changes in the X-ray emission flux.
