Authors: Yousif N.B.A. , Stepanova Diana , Astaubayeva Gulnar , Uandykova Mafura , Mikhaylov Alexey
Published: September 2024

Many financial crises have occurred in recent decades, such as the International Debt Crisis of 1982, the East Asian Economic Crisis of 1997–2001, the Russian economic crisis of 1992–1997, the Latin American debt Crisis of 1994–2002, the Global Economic Recession of 2007–2009, which had a strong impact on international relations. The aim of this article is to create an econometric model of the indicator for identifying crisis situations arising in stock markets. The approach under consideration includes data for preprocessing and assessing the stability of the trend of time series using higher-order moments. The results obtained are compared with specific practical situations. To test the proposed indicator, real data of the stock indices of the USA, Germany and Hong Kong in the period World Financial Crisis are used. The scientific novelty of the results of the article consists in the analysis of the initial and given initial moments of high order, as well as the central and reduced central moments of high order. The econometric model of the indicator for identifying crisis situations arising considered in the work, based on high-order moments plays a pivotal role in crisis detection in stock markets, influencing financial innovations in managing the national economy. The findings contribute to the resilience and adaptability of the financial system, ultimately shaping the trajectory of the national economy. By facilitating timely crisis detection, the model supports efforts to maintain economic stability, thereby fostering sustainable growth and resilience in the face of financial disruptions. The model’s insights can shape the national innovation ecosystem by guiding the development and adoption of monetary and financial innovations that are aligned with the economy’s specific needs and challenges.
Examining the constraints of moral knowledge in shaping ethical conduct in South Korean moral education: A critical analysis of Socrates’ art of measurement in Protagoras
Authors: Nam-Gung Hwan
Published: September 2024

Socrates argues that individuals can continue to behave morally when trying to explore virtue, distinguishing between copying a moral person’s actions and acting on the basis of virtue itself. This study proves the limitations of South Korea’s moral education, which values moral knowledge as a driver of moral behavior, by analyzing the art of measurement presented by Socrates as a method of recognizing virtue. Consequently, Protagoras was examined to identify the characteristics of the art of measurement, and “all pleasure is good” and “knowledge directly drives action” was problematized. The study concluded that moral knowledge is not a decisive factor in guiding moral behavior in the right direction.
A review of personal space and the factors affecting its perception in open-green areas from the perspective of landscape architecture
Authors: Bostancı Gizem , Dağlı Pelin Keçecioğlu
Published: September 2024

Landscape architects, who guide planning and design decisions by understanding the socio-cultural expectations, functional needs, and social behaviors of the community, create ideal spaces for people by integrating natural, social, cultural, and aesthetic factors with a holistic design approach in urban public areas. Public open green spaces are important urban areas that have a positive impact on people’s physical, mental, and emotional health. In this context, the concept of personal space, its impact on individuals, and related perception studies have been examined. In landscape design, criteria that affect individuals’ personal space distances and personal space perceptions have been identified, providing a basis for sustainable landscape design projects in public open and green spaces.
The Relationship of Social Withdrawal Motivations to Loneliness among Adolescents: Testing a Moderated Moderation Model of Self-determined Motivation for Solitude and School Climate
Authors:   Korea Univ. Institute of Educational Research, Lee Sunmyung , Lee Donghyung
Published: September 2024

The purpose of this study was to examine whether self-determined motivation for solitude (SDMS) and school climate play moderated moderating roles in the relationship between shyness, social avoidance, and loneliness among adolescents. For this purpose, self-reported measures of the study variables were collected from 818 high school students in a metropolitan city in Korea. SPSS 25.0 and Process Macro 4.2 were used for statistical analysis. The major findings were as follows: First, shyness and social avoidance were positively correlated with loneliness, while school climate was negatively correlated with loneliness. Second, SDMS and school climate each moderated the effect of shyness on loneliness. Finally, there was a significant moderated moderation effect of SDMS and school climate in the relationship between social avoidance and loneliness. These findings suggest that fostering positive school climate and self-determined motivation for solitude among adolescents with high avoidance motivation (such as shyness and social avoidance) may help diminish their loneliness. Educational implications, limitations, and suggestions for further studies were discussed.
Comparative Analysis of the Effects of Manure and Vermicompost on the Elasticity Modulus of Loam Soil in Different Moistures
Authors: Asadollahi Ali , Shahgholi Gholamhossein , Szymanek Mariusz , Dziwulska-Hunek Agata
Published: September 2024

This study aims to investigate the effects of manure and vermicompost in terms of soil elasticity modulus changes in loam soil. The uniaxial compression test measures the compressive strength of a soil cylinder without any lateral load. The modulus of elasticity was determined by plotting the strain-stress diagrams and calculating the slope of these diagrams. The increase in moisture and organic matter content significantly improved soil flexibility and decreased its elasticity modulus. It was found that adding animal manure had a greater effect on the flexibility of the soil as compared to vermicompost, while the elasticity modulus of the samples containing animal manure was lower. The interaction effect of moisture and the organic matter content indicated that the increase in humidity was more effective in the soil containing vermicompost as compared to the soil containing manure, such that when the manure rate was around 19%, the moisture increase had no significant impact on the elasticity modulus. It was found that adding organic matter was more effective at the low moisture level of 15.5% than at higher moistures where the effect of adding organic matter did not affect the soil elasticity modulus decrement as strongly.

The Importance of EU Taxonomy for Sustainable Development Reporting. Case Study of Entities Listed on the Warsaw Stock Exchange in Poland
Authors: Sulik-Górecka Aleksandra , Biały Witold , Strojek-Filus Marzena
Published: September 2024

The introduction of the obligation to prepare ESG reports taking into account EU Taxonomy is a challenge for enterprises, but at the same time opens up the possibility of using disclosures in this area to assess entities in the context of environmentally sustainable activities. Legal changes in the field of the Green Deal have been introduced in the last three years, and in the area of EU taxonomy this process is still ongoing, resulting in a deficit of research on the effects of implementing the new legal regulations. The main goal of our study is to assess the importance of the newly applicable ESG reporting and environmental disclosure requirements under EU Taxonomy in improving the quality and comparability of sustainability reporting and the creation of ESG ratings. A qualitative research method was applied based on multiple case studies using content analysis on the basis of ESG reports for 2021-2022 for entities listed on the Warsaw Stock Exchange. The research results indicate a very low level of activities classified as environmentally sustainable and taxonomy-aligned. Additionally, the results may also indicate problems with implementing the new solutions in reporting practice. At the same time, a positive impact is noted of the implementation of taxonomic reports on improving the comparability and detail of disclosures.

Authors: Pereira Junior Josceli Roberto Gomes , Arevalo Jorge Luis Sanchez
Published: September 2024

Objective: The aim of this study is to analyze the importance of various assets as safe havens (hedges) for investment protection, considering systemic risk events, such as the case of COVID-19.
 
Theoretical Framework: In the study, the behavior of the Brazilian Stock Exchange Indicator is discussed, considering the pandemic period, as well as its relationship with other important financial market assets, such as gold, oil, and the dollar.
 
Method: Due to the adequacy of the data, considering differences and cointegration, the methodology used in the study was the Autoregressive Distributed Lag (ARDL) model, proposed by Pesaran et al. (2001).
 
Results and Discussion: The results reveal significant implications for portfolio management in situations of financial risk, highlighting the volatility of the exchange rate and gold, as well as the impact of oil prices on the Brazilian stock market. The estimation of the error correction term found an adjustment speed of 5.7%, indicating a significant long-term association between the variables.
 
Research Implications: The research highlights that, in the short term, oil and gold prices affect stock indices differently compared to the exchange rate, while in the long term these effects are similar. Thus, for the exchange rate, entry and exit points for investments should be defined. The results are crucial for investment managers and policymakers, especially in contexts of systemic risk.
 
Originality/Value: The research provides valuable insights for managers and investors, highlighting the importance of understanding the historical behavior of economic variables across different time horizons. Future studies can explore alternative methodologies and consider various economic contexts to enhance the understanding of financial asset behavior, as each country may present a different reality.

A Blueprint to Dismantle Apartheid Spatial Differentiation? A Reflection on 25 Years of the White Paper on Local Government
Authors: Sithenkosi  , Ogochukwu Iruoma Nzewi
Published: September 2024

There is a significant international discussion on how government can tackle the issue of spatial inequality. The South African local government sphere presents one of the most visible examples of how historically deliberate geographical underdevelopment has created modern spatial inequalities. Local government is designed as perhaps one of the most egalitarian governance systems in the world. Constitutionally grounded and further articulated in the 1998 White Paper on Local Government (WPLG), local government in South Africa is designed to reflect the key tenets of an “ideal municipality.” This vision is based on a developmental, transformational local government committed to working with communities and individuals to find long-term solutions to their social, economic, and material needs while also improving their quality of life. Using reports, datasets from government databases, and articles, this article comprises a qualitative literature analysis to provide an assessment of the WPLG transformation promise using three indicators representing the ideal municipality provision: service delivery, governance, and local economic development. The article argues that developing appropriate intervention strategies within the present developmental local government milieu presents a service delivery quandary because, despite the principle of equitable distribution, the current design of local government has perpetuated inequity in the provision of public resources. In this case, residents in local wards are unable to support viable economic and service delivery alternatives. To buttress this point, a service delivery survey showed that the poorest (informal settlements and rural areas) communities in South Africa express the strongest levels of dissatisfaction with services.
The New Prison Narrative in Zimbabwe: Re-Imagining (In)Justice in the Second Republic
Authors: Nyambi Oliver
Published: September 2024

The prison has long functioned in Zimbabwe’s official post-colonial history as a symbolic, ideologised, and often politicised mnemonic of colonial injustice. This conception of the prison allows for its convenient summoning and implementation in hegemonic (neo)nationalist identity projects of the ruling Zimbabwe African National Union (Patriotic Front) (ZANU PF) party. As a metaphor of colonial oppression and injustice, the colonial prison enters ZANU PF’s “patriotic” narratives of self-legitimation as a historical testament of nationalist rites of passage to political power that define and ring-fence nationalist sacrifice. It would be fascinating, in the context of the proliferation of various forms of prison narratives in post-colonial Zimbabwe, to consider what is (un)changing with the meaning of the prison vis-à-vis its paradoxical function as, on one hand, a symbolic monument archiving liberation struggle sacrifice and, on the other, a site of inspiration for incarcerated opposition activists to chart alternative forms of liberation from “liberation.” Using a purposefully selected set of prison writings and anecdotes, mostly in the form of epistles and speeches by jailed Zimbabwean opposition activists, this article argues that new prison narratives use the prison as an aesthetic and discursive metaphor for unsettling the state’s epistemic justice in Zimbabwe. Invoking Maria Pia Lara’s ideas about the disclosive effect of narratives by oppressed groups, the article looks at how certain aesthetic constructions of political victimhood in prison narratives create a new logic of justice. It explores the various ways in which the post-colonial prison in Zimbabwe is re-imagined in emerging prison narratives that portray it as emblematic of a new form of injustice that underscores the inherent instability of post-colonial justice in independent Zimbabwe.

Authors: Islam Md. Robiul , Rahman Abdur , Islam M. Rezaul
Published: September 2024

In the study, we aimed to assess the public perceptions of the prevalence, satisfaction and challenges of electronic health (e-health) services in Bangladesh. An online survey with a self-administered structured interview was conducted with 150 respondents to collect general perceptions from people living in rural and urban areas. The study revealed that the prevalence of e-health services was moderate in Bangladesh. During the COVID-19 pandemic, people accessed online vaccine registrations (58%) and telemedicine (23%) and downloaded COVID test reports (17%). The study did not find an association between e-health services and the respondents’ age, gender, living conditions and marital status based on the results of the chi-square test and the Mann-Whitney U test (p > 0.05). Spearman’s correlation coefficient confirmed that individuals were moderately satisfied with their access to e-health services (r = .536), the availability of updated COVID-related information on websites (r = .585), and government advertisements (r = .547). The respondents reported major challenges such as high internet costs, lack of awareness, insufficient internet speed, and an information gap regarding e-health services in Bangladesh. These results offer important insights to laypeople, health experts and practitioners, policymakers and government health authorities.

Published: September 2024

Pembunuhan berencana merupakan tindakan kriminal yang sangat keji oleh karena menghilangkan nyawa seseorang dan direncanakan sedemikian rupa baik secara pribadi maupun kelompok. Fokus penulisan ini ditujukan untuk menganalisa serta memahami kasus pembunuhan berencana yang dilakukan Ferdi Sambo terhadap Brigadir J dari sudut pandang hukum dan moral. Tujuan dari penulisan ini adalah untuk memahami bahwa kasus pembunuhan berencana yang dilakukan Ferdi Sambo terhadap Brigadir J tidak dibenarkan secara hukum dan moral sehingga sanksi yang diberikan sangat tegas. Metode penulisan ini menggunakan analisis kasus secara kualitatif menggunakan pendekatan hukum, moral dan literasi. Temuan dari penulisan antara lain bahwa kasus pembunuhan berencana yang dilakukan oleh Ferdy Sambo tidak dibenarkan secara moral, dan norma obyektif serta norma subyektif. Alasannya karena pembunuhan mengakibatkan hilangnya nyawa seseorang, apalagi membunuh dengan direncanakan adalah suatu kekejian. Membunuh dengan melibatkan orang lain merupakan tindakan yang bertentangan dengan nilai kemanusiaan yang dianut oleh masyarakat pada umumnya dan juga bertentangan dengan hati nurani yang benar. Relevansi norma obyektif dari kasus pembunuhan berencana yang dilakukan oleh Ferdy Sambo terhadap Brigadir J dalam pandangan moral menunjukkan bahwa perilaku yang didasarkan pada kebebasan individu cenderung mengarah pada hal negatif.

Salah satu hak yang dimiliki manusia adalah hak untuk hidup, di mana hal ini terkait juga dengan Upaya penghapusan kemiskinan agar manusia dapat memenuhi kebutuhan hidupnya. Manusia harus dilindungi dari berbagai ancaman  termasuk ancaman dari kemiskinan yang merupakan bagian dari Sustainable Development Goals (SDG’s) di mana setiap manusia atau individu harus dijamin oleh negara agar tidak menderita kemiskinan. Tujuan yang pertama dari SDG’s adalah Menghapuskan Kemiskinan, namun di sebagai belahan bumi, masih terdapat kemiskinan sehingga mengancam kehidupan mereka, di mana mereka tidak dapat memenuhi kebutuhan hidupnya termasuk akses kesehatan, nutrisi buruk bagi anak-anak dan pendidikan yang baik. Salah satu penyebab kemiskinan adalah menurunnya kualitas lingkungan, terutama untuk mereka yang mengandalkan alam untuk kehidupan sehari-hari seperti nelayan dan petani, di mana bila lingkungan rusak, maka hasil tangkapan berkurang dan hasil panen pun menurun. Permasalahan yang akan dibahas dalam tulisan ini adalah bagaimana pengaturan tentang perlindungan lingkungan  khususnya yang terkait dengan lingkungan laut dan lahan serta peran negara agar tidak dapat mengurangi kemiskinan. Metode penelitian yang digunakan adalah Yuridis-Normatif yaitu kajian Pustaka baik dari buku, jurnal,  dan aturan di Indonesia. Salah satu cara untuk menanggulangi kemiskinan adalah dengan menjaga atau melindungi lingkungan agar tidak tercemar atau tidak terjadi penurunan kualitasnya. Pengaturan tentang perlindungan lingkungan dan juga peran atau tanggung jawab negara diperlukan sebagai upaya untuk menanggulangi kemiskinan. Aturan di Indonesia sudah cukup untuk melindungi lingkungan.  Indonesia juga telah ikut serta dalam pembahasan mengenai tujuan Pembangunan berkelanjutan ini yang menghasilkan suatu Deklarasi SDG’s pada tahun 2015. Komitmen internasional ini menjadi tanggung jawab masing-masing negara agar dapat dilaksanakan di negaranya. Diharapkan agar aturan yang  ada tentang perlindungan lingkungan dapat diterapkan termasuk pula adanya peran serta negara atau pemerintah, sehingga lingkungan tetap terlindungi dan kemiskinan dapat ditanggulangi.

Revisiting ultrasound assessment of median nerve in carpal tunnel syndrome: A review
Authors: Upadhyaya Vaishali , Choudur Hema Nalini
Published: September 2024

Carpal tunnel syndrome (CTS), which occurs due to compression of the median nerve as it traverses the carpal tunnel at the level of the wrist joint, is the most common entrapment neuropathy. Conventionally, clinical evaluation and electrodiagnostic tests such as nerve conduction velocity and electromyography have been the mainstay of diagnosis in patients with clinically suspected CTS. In recent times, ultrasound (US) has become increasingly popular for diagnosing CTS. However, despite its widespread popularity, the criteria used for diagnosis vary widely. This paper aims to discuss multiple studies which evaluate the role of US in CTS and try to clarify which US criteria can be used with ease and accuracy in daily clinical practice.

Fenton-Enhanced zero-valent iron powder oxidation: Investigating transformation products of antimicrobials and its removal
Authors: Goswami Anuradha , Jiang Jia-Qian , Joanne Roberts , Petri Michael
Published: September 2024

The occurrence of pharmaceuticals and pesticides in water is of concern due to their hazardous effect on the environment. Such micropollutants deteriorate environmental quality and can induce antimicrobial resistance in pathogenic bacteria. Thus, removal of these emerging contaminants is a necessity and thus requires a clear understanding of the effective treatment and mechanistic approach utilized in degradation and removal. Frequently, treatment systems are optimized for the removal of contaminants while the formation of transformation products and their removal are not targeted. We utilized our established iron powder catalyzed Fe (0) Fenton Oxidation treatment to study the degradation of emerging contaminants — sulfamethoxazole, gabapentin, diuron, and triazine class pesticides. We used state-of-the-art mass spectrometry to establish the common oxidative mechanistic approach after identifying the transformation products formed during the Fe (0) Fenton Oxidation processes. Fenton transformed product was produced after 60 min reaction time when treatment was initiated after adding the optimized H2O2 and iron powder Fe (0)) in a micropollutant solution adjusted to pH 5. About 5-to-7 transformed products of each micropollutant were identified and predicted to have low toxicity risk to aquatic organisms. The oxidative degradation pathway of micropollutants illustrates the shared oxidative mechanism where the aliphatic chain of the heteroatom: Sulphur (R—S—R as thiosulphate), functional groups (R—C=O, R—COOR, R—NH2, R— NH=O—N) and alkyl chain present in the target compound was suggested as the prime region of hydroxyl radicle (•OH) attack. The tandem mass spectrometry estimated the evolution of sulfamethoxazole-transformed product formation and removal during the treatment. The informed optimization of Fe (0) Fenton treatment, confirmed through MS2 was established at 40 min reaction time at which both the sulfamethoxazole and its transformed product were reduced to trace levels (ngL-1).
Star-like docking to F mutations of respiratory syncytial virus
Authors: coll julio
Published: September 2024

The respiratory syncytial virus (RSV) causes abundant annual fatalities on young children and elder adults by infecting human cells mediated by RSV fusion (F) surface homotrimeric proteins. Despite their RSV fusion in vitro inhibitors, anti-F therapeutic molecules are not yet clinically available because of emergent resistant mutations. Here, alternative therapeutic strategies are explored to dock mutated F protein models. For that thousands of trimeric drug-like candidates were computationally generated/selected by parent-children co-evolution. New top-children candidates may help experimental tests since they display 3-fold star-like molecules fitting similar trimeric F cavities than previous in vitro inhibitors but improved higher sub-nanoMolar affinities. Additionally, some top-children also successfully targeted F mutations previously implicated in RSV fusion drug-resistances

The pentavalent oxidation state of praseodymium – a long-sought connection between lanthanide, early-transition, and actinide metal redox chemistries – has only been identified in gas-phase or matrix isolation environments. We report the low-temperature characterization of a molecular praseodymium complex in the formal +5 oxidation state, [Pr5+(NP(tBu3)4][X–] (where tBu = tert-butyl and X– = tetrakis(pentafluorophenyl)borate or hexafluorophosphate). Single-crystal X-ray diffraction, solution-state spectroscopic, solution magnetometric, density functional theory, and multireference wavefunction-based methods indicate a highly multiconfigurational, singlet ground state. An inverted ligand field drives this unique electronic structure, which establishes a critical link in understanding the bonding of high-valent metal complexes across the periodic table.

Riboswitches control gene regulation upon external stimuli such as environmental factors or ligand binding. The fluoride sensing riboswitch from Thermotoga petrophila is a complex regulatory RNA proposed to be involved in resistance to F- cytotoxicity. The details of structure and dynamics underpinning the regulatory mechanism are currently debated. Here we demonstrate that a combination of pulsed electron paramagnetic resonance (ESR/EPR) spectroscopies, detecting distances in the angstrom to nanometre range, can probe distinct regions of conformational flexibility in this riboswitch. PELDOR (pulsed electron-electron double resonance) revealed a similar preorganisation of the sensing domain in three forms, i.e. the free aptamer, the MgII-bound apo, and the F--bound holo form. 19F ENDOR (electron-nuclear double resonance) was used to investigate the active site structure of the F--bound holo form. Distance distributions without a priori structural information were compared with in silico modelling of spin label conformations based on the crystal structure. While PELDOR, probing longer distances, revealed varying conformational flexibility of the RNA backbone, ENDOR indicated low structural heterogeneity at the ligand binding site. Overall, the combination of PELDOR and ENDOR with sub-angstrom precision gave insight into structural organisation and flexibility of a riboswitch, not easily attainable by other biophysical techniques.

Developing dopant-free hole-transporting materials (HTMs) with high hole mobilities is essential to achieve efficient and stable inorganic perovskite solar cells (PVSCs). Herein, two linear organic small molecules IDTT-EtCz and IDTT-PhCz with D–A–D’–A–D configurations are designed and synthesized via two high yield steps, and they are successfully employed as HTMs with effective defect passivation in all-inorganic PVSCs. Notably, the IDTT-PhCz exhibits a deeper highest occupied molecular orbital energy level comparing with that of IDTT-EtCz, along with the enhancement of antioxidant activity towards iodine. Interestingly, IDTT-PhCz with aromatized terminal groups shows significantly increased short contacts and higher hole mobilities than IDTT-EtCz. Furthermore, the IDTT-PhCz has been proven to possess effective surface passivation capability and appropriate energy level alignment at the hole-extraction interface, efficiently suppressing recombination loss and enhancing charge collection. Finally, CsPbI3-based PVSCs with IDTT-PhCz as dopant-free HTM achieve a champion power conversion efficiency (PCE) of 21.0 %, which is one of the highest values reported thus far for all-inorganic PVSCs. The optimized device maintains over 90 % of the initial PCE after 500 hours at 60°C, indicating superior thermal stability. Additionally, the CsPbI2Br PVSC based on IDTT-PhCz exhibits an impressive PCE of 18.0 %, and a CsPbI2Br/organic tandem solar cell based on IDTT-PhCz achieves a record-high PCE of 25.0 % (24.66 % certified), which is the highest efficiency among the n-i-p perovskite/organic tandem solar cells to date. Overall, this work demonstrates the superiority and generalizability of the D–A–D’–A–D-type design strategy for achieving efficient PVSCs.

Matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI IMS) is a rapidly advancing technology for biomedical research. As spatial resolution increases, however, so does acquisition time, file size, and experimental cost, which increases the need to perform precise sampling of targeted tissue regions to optimize the biological information gleaned from an experiment and minimize wasted resources. The ability to define instrument measurement regions based on key tissue features and automatically sample these specific regions of interest (ROIs) addresses this challenge. Herein, we demonstrate a workflow using standard software that allows for direct sampling of microscopy-defined regions by MALDI IMS. Three case studies were included, highlighting different methods for defining features from common sample types – manual annotation of vasculature in human brain tissue, automated segmentation of renal functional tissue units across whole slide images using custom segmentation algorithms, and automated segmentation of dispersed HeLa cells using open-source software. Each case minimizes data acquisition from unnecessary sample regions and dramatically increases throughput while uncovering molecular heterogeneity within targeted ROIs. This workflow provides an approachable method for spatially targeted MALDI IMS driven by microscopy as part of multimodal molecular imaging studies.
