Authors:   Altai State University, T. Tishkina , K. Tishkina ,   Siberian Federal University
Published: December 2023

The Union of Soviet Socialist Republics existed from December 30, 1922 to December 26, 1991. During this period of time, significant successes were achieved in industry, agriculture, science and culture, and a victory was won over the Fascist conquerors was won in 1945. To the 100th anniversary of the formation of the USSR in Barnaul, there were exhibitions: “Soviet Porcelain” and “The Country of the Soviets” (the State Art Museum of the Altai Territory); “The USSR in the Mirror of Art” (exhibition hall of “Museum “City”); “Art that has become History” (“Shchetinins Art Gallery”); “Greetings from the USSR” (Altai State Museum of Local Lore). The exhibitions displayed photos, works of fine and decorative art, and items of material culture created in the 1920s-1980s. The purpose of the exhibitions is to expand visitors’ knowledge of the history of Russia, form a positive image of the USSR in the minds of the younger generation and improve the patriotic mood of the citizens.
ARCHAEOLOGY IN THE MUSEUM OF LOCAL LORE: MODERN APPROACHES TO THE PRESENTATION OF ALTAI HERITAGE
Authors:   Altai State Museum of Local Lore, O. FILIPPOVA
Published: December 2023

The publication deals with the presentation of scientific archaeological knowledge in the space of the Museum of Local Lore. Archaeological collections are an important component of most collections of local history museums in Russia. Using the example of the Altai State Museum of Local Lore, the experience of implementing exhibition and cultural and educational projects related to the archaeology of Altai is demonstrated. The project “Secrets of Stone Vaults”, which combines not only the topic of archaeology, but also the natural and cultural heritage of the region as a whole, is cited as successful practices. In addition to presenting cave complexes as unique archaeological sites, the authors of the project touched upon issues of environmental protection, eco-tourism, speleology and paleontology. The experience of the region’s participation in the All-Russian action “Open Days of Archaeology” is given as cultural and educational events designed for a wide audience.
National-Territorial Delimitation in Central Asia in the 1920s: the Emergence of Border Disputes
Authors: Hamidov M.B. , Kurnykin O.Yu.
Published: December 2023

The formation of the administrative borders of the Central Asian republics is connected with the historical events of the 1920s, the Bolshevik policy of division, or national-territorial demarcation of this vast Islamized region in the center of Eurasia. The Central Asian states that existed during the imperial period (Bukhara Emirate, Khiva and Kokand khanates), as well as during the initial period of Sovietization of the region (Turkestan ASSR, Bukhara NSR and Khorezm NSR) were not national entities. After the end of the Civil War, the Bolsheviks, within the framework of the "policy of self-determination of peoples", assumed that each state was to unite the population within a single nation, defined primarily by ethnicity. However, the implementation of these guidelines ran up against the lack of clear ethnic boundaries and the multiculturalism of the region; conflicts over the distribution of water, pasture, and minerals were not uncommon in the delimitation of borders. The territorial delimitation in the Fergana Valley, perceived by the Bolsheviks as a stronghold of the antiSoviet movement in Central Asia under the slogans of Pan-Islamism and Pan-Turkism, was especially difficult. It is no coincidence that the Fergana Valley, which was a single economic, cultural and historical complex, turned out to be divided between three state formations, the border disputes between which have not yet been finally resolved.
J.R.R. Tolkien's Memory of the First World War in His Works
Authors: Ulyanov P.V.
Published: December 2023

This article examines the problem of perception of the First World War and its events in the context of preserving the memory of it. The main emphasis is on the personal perception of military operations and their subsequent reflection in a work of art. We are talking about the work of the writers of the "lost generation of 1914", in whose novels and stories the memory of a historical event is preserved. The central issue of the studied memory of the "Great War" was the work of the British writer and scientist J.R.R. Tolkien and his personal perception of the event, reflected in the epic novel "The Lord of the Rings". In modern historical science, the problem is poorly studied. The attempts of research scientists are based on the use of comparative historical and biographical research methods, which is why many issues are not taken into account. Therefore, the author aims to identify the subjects poorly studied by foreign and domestic researchers in the problem of perception of J.R.R. Tolkien events of the First World War. The main task is aimed at identifying and systematic analysis of the main storylines of "The Lord of the Rings" and comparing them with the data of the letters of the British writer and the memoirs of other participants in the hostilities. The author comes to the conclusion that the formed J.R.R. Tolkien and the image of the First World War reflected in the novel "The Lord of the Rings" is his personal assessment, and for its study it is not enough to use predominantly comparative historical and biographical methods of research.
Classroom Self-Governance Meetings as an Experience of Democracy as a Way of Life
Authors:   Center For Educational Research, Kim Hyung Shin , Kim Misook
Published: December 2023

Purpose: To make the class an experience of becoming a space for democratic life, this study designed the operating principles of a self-governing council that can foster democratic citizenship and analyzed how students experience democracy while conducting self-governing meetings according to theestablished rules.
Methods: The researcher employed an action research method and analyzed data from a total often self-governance meeting transcripts, student records, and in-depth interview materials.
Results: As students formed a strong cooperative relationship with teachers, they recognized themselves as partners with teachers possessing decision-making authority, and demonstrated a tendency to treat each other as equal citizens while experiencing mutual respect among students. The agendaof the classroom self-governance meetings exhibited a shift from passive and constraining autonomy to proactive autonomy involving discussions on structural constraints. The dialogue culture formed through nonviolent dialogue and the circle process helped to form and maintain an attitude to accept various values and position, along with attitude of mutual respect and treating each other as equal citizens.
Conclusion: As students experienced democracy in their school lives, they recognized themselves as agents of school transformation and became agents of innovation capable of reshaping the school community. Therefore, effective democratic citizenship education should be integrated into teachertraining, and the national curriculum should be meticulously designed to facilitate students' growth as democratic citizens within their school lives.
Analysis of the link between the Social Studies Curriculum and Korean textbooks for curriculum convergence
Authors:   Center For Educational Research, Rhee Seo Young
Published: December 2023

Purpose: This study presents basic research to find a way to effectively form subject knowledge, skills, values, and attitudes by converging subject education so that education for the purpose of learner holistic growth can be realized. The purpose of this study was to analyze the implementation aspectsof the Social Studies Curriculum in Korean textbooks.
Methods: After a Doctor of Education examined various materials presented in elementary Korean textbooks and reviewed documents classified according to the Social Studies Curriculum content system the distribution of social studies curriculum areas and core concepts, and the placement and contents of grade groups in Korean language textbooks were analyzed.
Results: A total of fifty-nine pieces of material related to the Social Studies Curriculum included in Korean textbooks appeared in all areas, but only 47.7% of the core concepts were covered. In particular, the core concepts of a “sustainable world” and “sustainable environment” were most often addressed. However, only one 'economy' area was included. The data included in the 5th and 6th grades were 1.68 times more than the 3rd and 4th grades. The content data of the Social Studies Curriculum assigned to Korean textbooks in the same grade were 74%. Among the materials contained in the Korean textbooks in the 3rd and 4th grades, 50% dealt with the contents of the 5th and 6th grades of the Social Studies Curriculum.
Conclusion: The contents of the Social Studies Curriculum were not reflected in the materials included in the Korean textbooks in a balanced manner, and in some cases were not suitable for the grade group hierarchy. In terms of subject convergence, it is a desirable form of subject convergence toplace materials that deeply expand what is learned in Social Studies in the same grade group or to experience it before learning about it in Social Studies. This is expected to not only be an opportunity to reduce the learning burden on learners, but to inspire interest in learning. Accordingly, it is proposed to elaborate the criteria for selecting the content to be dealt with in Korean language textbooks for each area of the Social Studies Curriculum and selecting specific target areas for Korean language textbooks.

Exploring the use of eye tracking for the Multimodal Literacy of Struggling Readers
Authors:   Center For Educational Research, Kang Seohee , Lee Kyeonghwa
Published: December 2023

Purpose: This study explored the possibility of using an eye-tracking device to study the multimodal literacy of struggling readers.
Methods: For this purpose, literature on how multimodal texts are handled in the education plan for struggling readers was reviewed, and the researchers examined how multimodal literacy has been reviewed in studies of Korean language education using current eye tracking devices.
Results: In the current eye tracking research, there were few studies that focused on the struggling readers, and among the eye tracking indicators, data related to fixation was mainly used. The results of this study indicate that rather than solely drawing upon quantitative data derived through tracking in the moment, the focus on utilizing qualitative data derived from this, such as post-reading examination for oral statements has validity.
Conclusion: The study revealed that there is a need to closely explore several aspects of the reading of multi-modal texts by poor readers, and when using eye tracking devices, it is necessary to consider the characteristics of struggling readers and explore their reading processes.
A Qualitative Study on Perceived Challenges and Suggestions for Enhancing Student Suicide Prevention and Interventions Among Teachers
Authors:   Center For Educational Research, Lee Eun Sul , Kim Eunha , Park Jisun , Kang Mikyoung
Published: December 2023

Purpose: This study was conducted to explore the experiences of teachers regarding adolescent suicide prevention and crisis intervention at school.
Methods: An online survey using open-ended questions was administered to teachers currently working in elementary, middle, and high schools in South Korea. A total of one hundred responses were collected and analyzed using a Consensual Qualitative Research-Modified method.
Results: As a result, concerning ways that teachers employ in response to student suicidal behavior and crises, five categories of in-school interventions (e.g., student counseling, prevention-focused education, and referral to Wee-class) and two categories of external interventions (e.g., collaboration with relevant organizations, parent counseling, and cooperation requests) were emerged. Secondly, four areas of difficulties perceived by teachers were identified. These areas include administrative challenges(e.g., complex procedures, unclear responsibility, and delegation of responsibility), difficulties arising from counseling capabilities (e.g., lack of professional knowledge and experience, limitations in teachers' roles and authority), challenges related to parents or guardians (e.g., uncooperative attitudes of parents), and student-related difficulties (e.g., difficulties in self-disclosure). These areas were further broken down into a total of 18 categories. Thirdly, teachers' perspectives on improving the process of student suicide prevention and crisis intervention led to the identification of four areas and 18 categories. The areas were administrative (e.g., simplification of procedures, manual development),counseling-related (e.g., workforce expansion, teacher training support to enhance capabilities), student-related (e.g., strengthening psychological education and activities), and parents orguardians-related (e.g., improving parental awareness).
Conclusion: Based on the findings of this study, we discussed the implications for education and policies aimed at enhancing the suicide prevention and crisis response capacity of teachers, including mental health literacy education for teachers and students, alleviating the mental health-related workload of general teachers, and enhancing the clarity of their directions.

Authors: Enyiukwu David , Amadioha Anderson Chidi , Bassey Inemesit Ndarake
Published: December 2023

Rots and mycotoxin contamination of agro-produce are prevalent in tropical world. Aspergillus flavus is a major mycotoxigenic rot contaminant of tubers in Abia state, Nigeria. Consumption of mycotoxin contaminated foodstuffs accounts for 25% of medically important human diseases in Nigeria. The objective of this study was to assess antifungal activity of Alchornea cordifolia against A. flavus a mycotoxigenic rot pathogen of stored tuber produce both in vitro and in vivo.  Isolates were made from rotted yam tubers and pathogenicity test carried out to confirm A. flavus as pathogen. Five concentrations (100-500 mg mL-1) of methanol leaf extracts of the plant and thiophanate-methyl–a standard fungicide–were evaluated against the growth of the fungus in culture and pathogen-induced rot development and spread in vivo. The experiment was made up of 7 treatments and 3 replicates laid out in CRD. The plant leaf extract demonstrated varying levels of inhibition of A. flavus in vitro and rot development and spread in living tissues of yam. About 56.38%–68.22% and 67.245–80.01% inhibition was recorded by 100 mg mL-1 and 500 mg mL-1 of A. cordifolia extract for spore germination respectively whereas the same concentrations reduced rot development from 60% in the control experiment to 21.80% and 12.10% respectively which compared favorably (P<0.05) with standard fungicide, thiophanate-methyl. The plant demonstrated strong antifungal activity in vitro and minimized A. flavus induced rot advancement in living yam tissues.

Uplatňování zákazu diskriminace ve státní službě
Authors: Tomšej Jakub
Published: December 2023

The article discusses the application of the principle of equal treatment and the prohibition of discrimination in the context of public service. While employees who feel discriminated against often resort to legal action in civil courts or raise discrimination claims in other civil proceedings, the situation in employment relationships within the public service is less clear. The author examines how the law on public service refers to the relevant provisions of the Labor Code and explores the compatibility of the regulations designed for employment relationships with the specific nature of public service relationships. The article also emphasizes the importance of addressing discrimination claims in the appropriate procedural framework. Despite the increased element of subordination in public service, the principle of equal treatment and the prohibition of discrimination can still be invoked by public servants, as European law does not allow otherwise. The article analyzes the case law of the Czech supreme courts and its consequences.
Odškodnění újmy způsobené neozbrojenému státnímu zaměstnanci služebním úrazem
Authors: Štefko Martin
Published: December 2023

The subject of this article is the regulation of compensation for injury caused by a service accident to a civil servant. It is a sad example that service law does not offer unarmed civil servants a better regulation of injury compensation, even if they have suffered such injury because of the violence of a client to whom they were providing services in the interest of the Czech Republic. In conclusion, it is noted that even the Czech Republic cannot afford to squander the potential of its civil servants by not providing them with tangible benefits in the event of an on-duty injury, as such civil servants will not normally be motivated to perform their civil service effectively. We use the Swiss regulation and case law to depict that Swiss case law is and should be an inspiration even for Czech judges. A key observation concerns Swiss case law on the test applied in assessing whether or not mental illness is an occupational disease.

Přeshraniční znečištění v případu úniku kyanidu z těžebního provozu v Baia Mare: mezinárodněprávní aspekty
Authors: Hlušičková Denisa , Vícha Ondřej
Published: December 2023

The following paper traces the circumstances of the 2000 mining accident in the Romanian town of Baia Mare, which has been described as one of the worst environmental disasters since Chornobyl. Following this, the authors analyze the international legislation in force at the time of this accident and mention two types of obligations resulting from international treaties in force at the time, to which Romania was also a contracting party. At the turn of the millennium, there was a lack of legislation at the international and European Commission level to regulate this waste management process, making the whole process riskier and, in some cases, was also the reason for mining accidents associated with cyanide leaks into the environment. The authors describe the changes in international law adopted in response to the mining accidents, cite the case-law of the ECtHR related to the Baia Mare accident case (case Tǎtar v Romania). The authors leave aside the European and Czech aspects of the issue, which they will focus on in a separate article.
FedGTA: Topology-Aware Averaging for Federated Graph Learning
Authors: Li Xunkai , Wu Zhengyu , Zhang Wentao , Zhu Yinlin , Li Rong-Hua , Wang Guoren
Published: December 2023

Federated Graph Learning (FGL) is a distributed machine learning paradigm that enables collaborative training on large-scale subgraphs across multiple local systems. Existing FGL studies fall into two categories: (i) FGL Optimization, which improves multi-client training in existing machine learning models; (ii) FGL Model, which enhances performance with complex local models and multi-client interactions. However, most FGL optimization strategies are designed specifically for the computer vision domain and ignore graph structure, presenting dissatisfied performance and slow convergence. Meanwhile, complex local model architectures in FGL Models studies lack scalability for handling large-scale subgraphs and have deployment limitations. To address these issues, we propose Federated Graph Topology-aware Aggregation (FedGTA), a personalized optimization strategy that optimizes through topology-aware local smoothing confidence and mixed neighbor features. During experiments, we deploy FedGTA in 12 multi-scale real-world datasets with the Louvain and Metis split. This allows us to evaluate the performance and robustness of FedGTA across a range of scenarios. Extensive experiments demonstrate that FedGTA achieves state-of-the-art performance while exhibiting high scalability and efficiency. The experiment includes ogbn-papers100M, the most representative large-scale graph database so that we can verify the applicability of our method to large-scale graph learning. To the best of our knowledge, our study is the first to bridge large-scale graph learning with FGL using this optimization strategy, contributing to the development of efficient and scalable FGL methods.

Evaluation of systemic inflammatory and fibrosis indices in Saprochaete capitata infections: a retrospective case-control study
Authors: Cakir Nuri
Published: December 2023

Objectives

Evaluation of inflammation and liver fibrosis by using well established indices of serum biomarkers in hepatitis caused by viral agents has been reported in recent studies. But the diagnostic performance and prediction of liver damage in S. capitata infections has not yet been reported. The aim of the current study was to investigate the levels of systemic inflammatory indices based on liver enzymes and platelets, their effectiveness in detecting S. capitata infection and its degree of damage to the liver.

Methods

We investigated the diagnostic performance of seven serum inflammation and fibrosis markers as fibrosis-4 (FIB-4) score, AST/platelet ratio (APRI), AST/ALT ratio (De Ritis ratio), albumin/ALP ratio (AAR), platelet/albumin ratio (PAR), pan-immune-inflammation value (PIV) and GGT/platelet ratio (GPR) in total 62 S. capitata infected patients using cut-offs through receiver operating characteristics (ROC) analysis.

Results

Area under the curve of FIB-4 score was statistically significantly higher than ones of De Ritis ratio, AAR, PIV, APR, GPR, APRI index in determining liver damage in patients with S. capitata. The optimal cut off point for FIB-4 score was defined that the levels above 27.57 for FIB-4 score may be used for the diagnosis of S. capitata with 89 % of sensitivity and 91 % of specificity.

Conclusions

Serum fibrosis and immune-inflammation indices are independent, useful predictors, and FIB4 score is superior to the others in the diagnosis of inflammation and liver damage in S. capitata. These biomarkers may also be useful to specialists to follow up on the medical processes of these patients.
Uncovering flow dynamic behaviors underlying oil–gas–water three phase flow using multivariate synchrosqueezing transform
Authors: OuYang Lei , Ren Weikai , Jin Ningde
Published: December 2023

Oil-gas-water three-phase flow is distinguished by its intricate flow pattern. The analysis of experimental observations to reveal the oil-gas-water three phase flow’s dynamic behavior remains a challenging task. In this paper, firstly, a simulation investigation to compare the multivariate pseudo-winger distribution (MPWD) and multivariate synchrosqueezing transform (MSST) is presented. The cross term may be suppressed while maintaining high time-frequency concentration, according to our research on multivariate synchrosqueezing transform. The time-frequency analysis of various vertical oil–gas–water three phase flow patterns is then conducted utilizing MSST. The results from this study reveal that in various frequency bands, slug flow, bubble flow, and churn flow exhibit considerable temporal frequency variances. The MSST can effectively uncover the intrinsic connection between signal fluctuations and flow structure, and promote the understanding of various patterns of flow.

A Metal-Organic Framework (MOF) based on a tricarboxylic acid ligand (H3L = biphenyl-2,4′,5-tricarboxylic acid), namely [Cd3(L)2(H2O)4] (1), had been prepared and characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction (PXRD), thermogravimetric analyses (TGA), and single-crystal X-ray diffraction. Fluorescence studies showed that 1 has high quenching efficiency for testing acetone and Fe3+ ions in aqueous systems. Therefore, it can be used as a new type of fluorescence probe to detect solvent molecules and metal ions in water.
Obsessive-compulsive severity, gender, and religiosity as predictors of personality trait scores
Authors: Muller Greg N. , Zaboski Brian A. , Joyce-Beaulieu Diana , Bailey Brittany , McCarty Ryan , Olsen Brian T. , McNamara Joseph P. H.
Published: December 2023

Obsessive-compulsive disorder (OCD) impacts 1%—4% of the United States population. Scrupulosity, or obsessions related to morality and religion, is the fifth most common obsession. Although clinicians and researchers may have ample assessment information about their clients, such as OCD severity, gender, and religious background, little research in the field has shown how these variables relate to personality factors. Using Amazon's Mechanical Turk, we recruited 230 participants to (a) determine if scrupulosity were predictive of openness and neuroticism while accounting for gender, OCD severity, and religiosity; (b) investigate whether religious identity interacted with scrupulosity when predicting openness and neuroticism; and (c) examine if gender identity contributed to openness and neuroticism. Using linear mixed models, we found that higher scrupulosity predicted lower levels of openness across all religious groups, and that higher scrupulosity was associated with higher negative emotionality for nonreligious individuals. Implications for practice and continued research are discussed.
Gender as the New Language of Teen Rebellion
Authors: Lopez David L. , Wortman Alejandra
Published: December 2023

The growing occurrence of adolescents with gender nonconforming identities appears to be associated with what the authors believe is the contemporary manifestation of the adolescent identity crisis phenomenon. This phenomenon is expressed through a deliberate rejection and reappraisal of conventional gender roles and norms. The adolescent identity crisis, as initially conceptualized by Erik Erikson (1956), constitutes an unconscious multifaceted phenomenon that is outwardly displayed within familial and societal frameworks. A historical overview of pertinent terminology is provided, followed by the presentation of four clinical vignettes chosen to exemplify this phenomenon, alongside the resultant family conflicts that often ensue. Additionally, an anonymized clinical case is presented, encompassing the evaluation process, the subsequent psychodynamic formulation, treatment considerations, parent work, and the available resources for patients and families. The clinical illustrations are case composites and the data disguised to protect patient privacy and confidentiality. A plea is made to the scientific community for in-depth long-term research into this clinical phenomenon.
The Good-Enough Donor: Sperm as a Good, Not-Me Possession
Authors: Lucey Brita Reed
Published: December 2023

Reproductive endocrinologists often recommend sperm donation to two groups of patients. The first are women with partners with azoospermia. The second are women who do not have a partner and yet desire to become a parent. This article focuses on a subset of women in these two groups who hesitate to accept this recommendation from their reproductive endocrinologist. Winnicott's writings on transitional phenomena, especially his description of how the infant creates good, not-me possessions, may be helpful in our understanding of some of these women's fantasies of sperm as a bad, not-me possession. Case material is used to highlight treatment recommendations that utilize a reframing of the understanding of the donor's motivation, which may create the possibility of an acceptance of sperm as a good, not-me possession. This moves the patient toward what Winnicott calls acknowledgement of indebtedness and toward what the patient may perceive as a good-enough donor.
Assessing Burdening Guilt and Its Correlates
Authors: Leonardi Jessica , Gazzillo Francesco , Gorman Bernard , Bush Marshall
Published: December 2023

Burdening guilt refers to the belief that one's emotions, needs, and ways of being are a burden to others, and is one type of interpersonal guilt proposed by the control-mastery theory (CMT). The aim of this article is to validate two new measures of burdening guilt. In the two studies conducted, we examined the psychometric properties of these scales and the relationship between burdening guilt and self-perceived burden (burdensomeness), self-esteem, shame, anxiety, depression, mental health, attachment insecurity, adverse childhood experiences, social desirability, empathy, and suicidal ideation. In Study 1, we presented a newly developed Burdening Guilt Rating Scale (BGRS) and its correlation with measures of the abovementioned dimensions. In Study 2 we verified, through confirmatory factor analysis and correlation techniques, the possibility of expanding the Interpersonal Guilt Rating Scale-15 with a shorter, 5-item burdening guilt scale derived from the BGRS, and showed that this shorter scale correlates similarly to the longer one. Findings allowed us to validate these new scales providing empirical measures of burdening guilt—a theoretical concept with important clinical implications.

El número creciente de adolescentes con identidad de género no conforme parece estar asociado a lo que los autores consideran ser la manifestación contemporánea del fenómeno de la crisis de identidad adolescente. Ésta se expresa a través de un rechazo deliberado y una revaloración de los roles y las normas convencionales de género. La crisis de identidad adolescente, tal y como fue conceptualizada inicialmente por Erik Erikson (1956), constituye un fenómeno multifacético inconsciente que se manifiesta en el contexto familiar y social. Los autores hacen una revisión histórica de la terminología pertinente, seguida de la presentación de cuatro bocetos clínicos, seleccionados para mostrar este fenómeno y los conflictos familiares que comúnmente se producen como resultado. A continuación, se presenta un caso clínico que abarca el proceso de evaluación clínica, formulación psicodinámica, consideraciones del tratamiento y el trabajo con los padres. Se enumeran las fuentes de información disponibles para los pacientes y sus familias. Las ilustraciones clínicas están compuestas de varios casos sobrepuestos y los datos se han alterado para proteger la privacidad y confidencialidad de los pacientes. Por último, los autores hacen un llamado a la comunidad científica a realizar indagaciones profundas a largo plazo sobre este fenómeno clínico.

Working memory (WM) maintenance relies on multiple brain regions and inter-regional communications. The hippocampus and entorhinal cortex (EC) are thought to support this operation. Besides, EC is the main gateway for information between the hippocampus and neocortex. However, the circuit-level mechanism of this interaction during WM maintenance remains unclear in humans. To address these questions, we recorded the intracranial electroencephalography from the hippocampus and EC while patients (N = 13, six females) performed WM tasks. We found that WM maintenance was accompanied by enhanced theta/alpha band (2–12 Hz) phase synchronization between the hippocampus to the EC. The Granger causality and phase slope index analyses consistently showed that WM maintenance was associated with theta/alpha band-coordinated unidirectional influence from the hippocampus to the EC. Besides, this unidirectional inter-regional communication increased with WM load and predicted WM load during memory maintenance. These findings demonstrate that WM maintenance in humans engages the hippocampal–entorhinal circuit, with the hippocampus influencing the EC in a load-dependent manner.
Dis:connectivity in Global History
Authors: Wenzlhuemer Roland
Published: December 2023

This chapter takes a historical perspective on processes of globalization. It evaluates how the historical sciences have hitherto applied the concept of globalization in historical research and examines some of the discontents that have emerged among historians in this context. The chapter claims that such discontents are often the consequence of an oversimplified, unidirectional understanding of globalization that ignores the role of disconnections in processes of global entanglement. It advocates a stronger focus on the interplay between global connectivity and disconnectivity (captured by the term dis:connectivity) and develops this claim with the help of examples from the history of telegraphy.
The Future of Global Capitalism: Crisis, Financialization, and Digitalization
Authors: Robinson William I.
Published: December 2023

The current moment in world capitalism is defined by three key developments. First, the system has become universal through globalization processes that date to the late twentieth century. Second, the system is undergoing a new round of restructuring and transformation based on a much more advanced digitalization and financialization of the entire global economy and society. Third, the system faces an unprecedented capitalist crisis that is as much economic, or structural, one of overaccumulation, as it is political, one of state legitimacy and capitalist hegemony. This crisis is also existential because of the threat of ecological collapse as well as the renewed threat of nuclear war and the danger of future pandemics that may involve much deadlier microbes than coronaviruses. Despite much talk of “deglobalization” and the breakdown of global supply chains in the wake of the coronavirus economic meltdown, world trade reached a record high in 2021. Transnational elites are pinning their hopes on a new wave of capitalist expansion and prosperity through digitally driven restructuring. Even if a new period of digitally driven expansion displaces the structural crisis temporally into the future, global capitalism will continue to generate social crises of survival and well-being for billions of people.

Recently, the rapid increase in population and industrialization has been created a lot of problems to water resources around the world. Most of the world population are exposed directly or indirectly towards heavy metals (HMs) such as Arsenic (As) contamination and thus making the water resources unfit for drinking and other human purposes. The current study was planned to find the As adsorption potential of novel thiolated cobalt-doped silver nanoparticles (Co-Ag NPs) under various environmental setups. In present work the Co-Ag NPs of sizes (20–22 nm) were synthesized through co-precipitation process. Adsorption of As with Co-Ag NPs was tested in batch experiments with respect light, pH and competing anions. Overall, the Co-Ag NPs effectively adsorbed the As in presence of sunlight (100%) and neutral pH (>99%). The removal of As was maximum (>99%) at CoAg NPs:As ratio of < 0.5:1. Similarly, the synthesized Co-Ag NPs did not showed the goodadsorption efficiency in dark condition about (21.4%) and only (11.1%) uptake at low and high pH respectively. Results of the current study showed that Co-Ag NPs can efficiently adsorb the As and reduce to non-toxic form i.e. below the WHO standard limit (10 µg/L)in drinking water.

The FexMo1-xS2 nanosheets with different Fe doping content x were grown on carbon nanotubes @ carbon cloth (CNT@CC) substrate using a hydrothermal method by varying the molar ratio of FeSO4·7H2O to Na2MoO4·2H2O in the precursor solution. The effect on HER, OER and overall water splitting (OWS) performance of Fe doping content x were studied. The FexMo1-xS2 nanosheets have the optimal HER and OWS performance for x=0.050 and the optimal OER performance for x=0.075. The overpotential at current density of 100 mA/cm2 and Tafel slope are 198 mV and 44.7 mVdec-1 for HER; and they are 279 mV and 24.5 mV/dec for OER in 1 M KOH electrolyte. The electrolytic cell using Fe0.05Mo0.95S2/ CNT@CC as both cathode and anode achieves a voltage of 1.69 V at current density of 100 mAcm-2 . The bifunctional catalytic activities of the FexMo1-xS2/ CNT@CC catalyst come from the synergistic effect between FexMo1-xS2 nanosheets and CNT.
AN ECOLOGICAL SYSTEMS APPROACH TO ASSESS THE WELL-BEING OF STREET CHILDREN IN ZIMBABWE: IMPLICATIONS FOR DEVELOPMENTAL SOCIAL WORK PRACTICE
Authors: Gunhidzirai Constance
Published: December 2023

This study reports on an assessment of the well-being of street children in Harare Metropolitan Province in Zimbabwe using the ecological systems approach. This study was underpinned by a quantitative approach which employed a semi-structured questionnaire as an instrument of data collection. Based on survey data of 202 street children who were purposively sampled, the findings revealed that street children lack access to food, education, accommodation, health care and proper sanitation. Therefore, street children require multi-component psychosocial and developmental interventions to enhance their well-being. The recommendations drawn from the findings were submitted to the Department of Social Development in Zimbabwe.

ADAPTING THE SOCIAL WORK CURRICULUM FOR RELEVANCE IN A SOUTH AFRICAN UNIVERSITY: A COLLABORATIVE AUTOETHNOGRAPHY OF SOCIAL WORK ACADEMICS DURING THE KZN FLOODS
Authors: Motloung Siphiwe , Mzinyane Bongane
Published: December 2023

This article adopts collaborative autoethnography in order to critically reflect on the experiences of social work academics who integrated disaster-specific approaches to the social work curriculum of two undergraduate courses in a South African university. This curriculum adaptation was in response to the KwaZulu-Natal floods of 2022. The integration of topics such as green social work and disaster-specific trauma responses at an undergraduate level of social work is advocated. These collaborative autoethnographic accounts contribute important lessons for social work education, practice and research in the era of natural disasters exacerbated by climate change. Keywords: Climate change, collaborative autoethnography, disasters, green social work, KZN flood, social work curriculum
