COMPUTER DIAGNOSTICS OF THE CONDITION OF SHIP ROLLING BEARINGS DURING THEIR OPERATION
Authors: Sharko Oleksandr , Stepanchikov Dmitro , Sharko Artem , Yanenko Artem
Published: October 2024

The results of statistical processing of vibration signals obtained during diagnostics of ship power plants during the operation process are offered. A distinctive feature of monitoring the technical condition of elements of ship power plants is the uncertainty in the fixation and duration of extreme loads. The peculiarity of computer vibration diagnostics of rotary mechanisms is determined, which is that, in particular, physical measurements of vibration signals require their use in mathematical models of the physical state of the bearing. Calculations of statistical characteristics of vibration signals in the time domain, such as standard deviation (Std), asymmetry (Skewness), kurtosis (Kurtosis), full range of oscillations (Peak2Peak), root mean square value (RMS), cross factor (CrestFactor), form- factor (ShapeFactor), impulse factor (ImpulseFactor), marginal factor (MarginFactor), energy (Energy). The variety of diagnostic signals leads to the need to merge indicators of different dimensions without losing available information into a single generalizing indicator, for which the method of principal components is used in the work. The methodology of statistical processing and practical implementation of diagnostics of vibration signals during the analysis of damage evolution of rolling bearings of turbochargers of marine power plants are described. A new computer information parameter of vibration diagnostics based on the analysis of the first principal component in the time domain and spectral excess in the frequency domain has been identified and experimentally confirmed. The use of new diagnostic parameters makes it possible not only to judge the degree of damage to the rolling bearing, but also to observe the dynamics of the development of the defect and make a relative forecast of the working life of the rolling bearing. A real practical situation is considered - computer diagnostics of vibration signals of ship rolling bearings of a point defect of an external defect of a rolling bearing ring. Determining the applicability of the principal component method to other types of defects showed their potential for vibrodiagnosis of defects located on the inner ring of the bearing and when the ball falls out of the holder.

Published: October 2024

Paper deals with the operations and equipment of the machine in the process of organizing production. During operation machines require maintenance and repairs, while in case of failure or machine wears it is necessary to replace them with new ones. For the process of replacement of old machines with new ones the term renewal is used. Qualitative aspects of the renewal process observe renewal theory, which is mainly based on the theory of probability and mathematical statistics. Devices lifetimes are closely related to the renewal of the devices. Presented article is focused on mathematical deduction of mathematical renewal models and determining optimal lifetime of the devices from the aspect of expenditures on renewal process.
CUDA Based Speed Optimization of the PCA Algorithm
Authors: Görgünoğlu Salih , Öz Kadriye , Çavuşoğlu Abdullah
Published: October 2024

Principal Component Analysis (PCA) is an algorithm involving heavy mathematical operations with matrices. The data extracted from the face images are usually very large and to process this data is time consuming. To reduce the execution time of these operations, parallel programming techniques are used. CUDA is a multipurpose parallel programming architecture supported by graphics cards. In this study we have implemented the PCA algorithm using both the classical programming approach and CUDA based implementation using different configurations. The algorithm is subdivided into its constituent calculation steps and evaluated for the positive effects of parallelization on each step. Therefore, the parts of the algorithm that cannot be improved by parallelization are identified. On the other hand, it is also shown that, with CUDA based approach dramatic improvements in the overall performance of the algorithm arepossible.

Jet Effect When an Attached Cavity Arises from a System of Pulse Pressure
Authors: Norkin Mikhail V
Published: October 2024

We consider the plane problem of the emergence of an attached cavity caused by the sudden action of impulsive pressures at some initial time. It is assumed that these pressures are distributed on the upper part of the boundary of a stationary circular cylinder immersed in liquid. A problem with unilateral constraints is formulated, on the basis of which the flow of liquid at the initial moment of time and the initial zone of separation of liquid particles are determined. At the next moments of time, an attached cavity is formed, the shape of which is determined based on the solution of the dynamic initial-boundary value problem of the theory of potential flows of an ideal incompressible fluid with free boundaries. The main unknowns in it are the velocity potential, the shape of the cavity, the dynamics of the separation points, and the perturbation of the external free boundary of the liquid. It is required to study the posed problem at short times, focusing on the behavior of the internal free boundary of the liquid near the separation points. When studying this problem, pressure in the cavern, which is created artificially, plays an important role. At low pressures, the internal free boundary of the liquid near the separation point is located on opposite sides of this point. In this case, the end part of the cavity resembles a stream of gas directed along the boundary of the cylinder towards the liquid.
The Influence of Motivation to Watch YouTube Unboxing & Makeup Haul and The Mediating Role of Parasocial Interaction on Purchase Intention of Cosmetic Products in Women
Authors: Kiyasatina Diandra Emery , Safitri Reza
Published: October 2024

The objective of this study is to examine the underlying motivations of YouTube users who watch unboxing and makeup haul videos on Tasya Farasya's YouTube channel. Additionally, the study aims to investigate the influence of these motivations on the intention to purchase cosmetic products, with the role of parasocial interaction as a mediator. This study employs the Uses and Gratifications theory as its principal theoretical framework. The research method employed is that of explanatory quantitative analysis, with data obtained from 271 respondents through a Google Form online survey. The data analysis techniques employed included descriptive analysis, exploratory factor analysis, path analysis, and the Sobel test. The findings revealed that the primary motivation for viewing unboxing and makeup haul videos by Tasya Farasya was to seek information. Furthermore, the findings of this study suggest that the role of parasocial interaction serves as a mediator between viewing motivation and purchase intention with regard to cosmetic products among women. The findings of this study indicate that parasocial interaction plays a mediating role in the relationship between viewing motivation and purchase intention with regard to cosmetic products among women. However, the generalisation of the results of this study is limited to the context of Tasya Farasya's YouTube unboxing videos, which are dominated by representations of Generation Z. It would be beneficial for future research to use a larger and more diverse sample in order to gain a more comprehensive understanding of the population and the diversity of responses and perceptions from various audience groups.

Published: October 2024

The study examined and modeled the walking behavior patterns of residents in Akure, Nigeria. A multi-stage sampling approach was used to collect relevant data for assessing and modeling the walking trip patterns. The questionnaires were administered to 300 participants between May to November 2019 (6 months) across three primary residential neighborhoods in the city; high-density, medium-density, and low-density areas. The obtained data were analyzed using SPSS software and subsequently modeled using multi-variable regression techniques. The study found that 48.7% of the sampled population preferred to walk, and 49.7% perceived walking as an alternative to motorized trips. Significant differences were observed in the socioeconomic characteristics of residents, such as age and income, across the residential zones (F = 54.731, p<0.001; F = 68.278, p<0.001). The key factors that greatly influenced decision of respondents to walk included socioeconomic factors, such as income, personal car ownership, educational qualifications, and employment status, with age and sex being the least significant socioeconomic determinants. Generally, the factors that motivated respondents to choose walking as a travel mode included its relative affordability, the lack of personal vehicles, awareness of health benefits, safety and security concerns, avoidance of motorized traffic congestion, and favorable weather conditions. The findings of this study have important implications for transportation planning. The paper recommends the need to incorporate non-motorized spaces and walkways into various levels of urban planning and implementation to foster a more walkable environment and encourage active transportation in the city.

Adaptive Frequency-Based Power Management for Off-Grid Hybrid Photovoltaic Converters
Authors: Gonschorowski Ezequiel , Cardoso Rafael , Carvalho Edivan Laercio , Stein Carlos Marcelo de Oliveira , Carati Emerson Giovani , Denardin Gustavo Weber , Da Costa Jean Patric
Published: October 2024

The intermittency in photovoltaic systems (PV) can lead to power quality issues, especially in off-grid applications. In these cases, adding an energy storage element helps to cope with the intermittency to provide adequate power to the local load. In this scenario, combining Li-Ion batteries and supercapacitors as a hybrid energy storage system (HESS) is powerful due to the battery's high energy density and the supercapacitor's high power density. The HESS demands adequate power management to operate adequately. This paper proposes an adaptive frequency-based power management for a Li-Ion battery and supercapacitor HESS applied to an off-grid PV converter. The main idea of this strategy is to guarantee a smoother current in the battery and reduce the power dissipation in the HESS. The smoother battery current transition helps avoid excessive battery stress and improves lifespan. The proposed strategy is compared with two other strategies. The results show that the proposed approach is more efficient in reducing the HESS' power dissipation and providing smooth current variations to the battery.
As causas do terremoto de Lisboa no ano de 1755 segundo o discurso do padre Gabriel Malagrida
Authors: Assis Guilherme Marchiori de
Published: October 2024

O artigo se divide em quatro partes. Em um primeiro momento, busca-se aludir à reconstrução da cidade de Lisboa após o terremoto de 1755. Após, apresentam-se as diversas argumentações sobre o evento cataclísmico, sendo elas de cunho ilustrado, jesuíticas ou mesmo teístas. Num terceiro momento se apresenta as consequências advindas ao padre Gabriel Malagrida, tal qual seu desterro para a vila de Setúbal, diante de suas pregações inflamadas contra os atos administrativos tomados pela coroa lusa. Conclui-se com a tentativa do jesuíta em reestabelecer laços com a corte Josefina, com o fito primeiro de evitar a condenação à morte que viria, de qualquer sorte, pela Inquisição. Os pontos do artigo objetivam explanar como a religião e o poder centralizado se distanciaram no período que vai de 1750 a 1758. Para tanto, valemo-nos da micro-história, apresentando-se como resultado aglutinador a influência do poder monárquico sobre a Companhia de Jesus.
Expressões do pensamento católico
Authors: Lanza Fábio , Neves Júnior José Wilson Assis , Guimarães Luiz Ernesto
Published: October 2024

O seguinte trabalho analisou o universo católico, com atenção à Arquidiocese de São Paulo a partir do seu meio de comunicação social o jornal semanário “O São Paulo”. O período estudado entre 1956 e 1985 selecionou de forma intencional editoriais do respectivo jornal, compreendendo as diferentes formas do pensamento católico e seu direcionamento ideológico; de forma complementar, recorremos ao arquivo de matérias censuradas d’O São Paulo durante a década de 1970 pelos militares, apoiados na doutrina de Segurança Nacional. Assim a problematização acerca do direcionamento do pensamento católico na Arquidiocese de São Paulo permitiu identificar o pêndulo entre o conservadorismo católico ultramontano e seu alinhamento com grupos de extrema direita – como o movimento da TFP – e a “opção preferencial pelos pobres” – fomentado pela Teologia da Libertação e vinculado aos movimentos sociais. Como resultado identificou-se a ocorrência de uma mudança na direção do pensamento católico paulistano consolidando uma perspectiva católica “progressista”.
“A Violência dos Pacíficos”
Authors: Coutinho Sérgio Ricardo
Published: October 2024

A perseguição a padres e a jovens trabalhadoras e trabalhadores católicos no Brasil foi o início das graves tensões abertas entre a cúpula militar e a cúpula eclesiástica organizada na Conferência Nacional de Bispos do Brasil (CNBB), logo após a implementação do Ato Institucional nº 5 de dezembro de 1968. Idealizada pelo jovem padre Joseph Cardijn, na Bélgica, a Juventude Operária Católica (JOC) foi reconhecida oficialmente em 1925 pela Santa Sé. No espaço de uma década, a JOC se espalhou pelo mundo e, em 1932, ela finalmente chegou ao Brasil. O golpe militar (1964) colocou em pauta novos desafios ao movimento operário e, consequentemente, à JOC, que passou a realizar uma reflexão mais profunda sobre as condições sócio-político-econômicas da classe trabalhadora naquele contexto latino-americano e brasileiro. Isto não passou despercebido pelos agentes do Estado autoritário, que começaram a acompanhar os militantes, sobre os quais caiu uma dura perseguição, culminando na prisão de muitas de suas lideranças. Foi nessa conjuntura que uma rede transnacional de solidariedade conduzida pela JOC Internacional expôs ao mundo, pelo menos ao Ocidente, o modus operandi do regime militar brasileiro que agredia frontalmente os Direitos Humanos. O artigo descreve as estratégias e experiências comuns vividas por uma organização sócio-política-religiosa numa cultura política marcada por um regime de força em que o elemento principal e aglutinador foi a solidariedade de caráter político e as formas de luta e agir político para além da ação coletiva.

ИТ-продукт: уточнение понятия (в печати)
Authors: Николаенко Валентин
Published: October 2024

Целью настоящей статьи является уточнение понятия «ИТ-продукт», которое позволит гармонизировать согласованность проектных целей, интересов и ожиданий заинтересованных сторон, а также снизить вероятность материализации комплаенс- и проектных рисков. Для достижения поставленной цели автором настоящей статьи был проведен анализ абсолютных синонимов и близких по смыслу понятий, которые применяются ИТ-субъектами (ОКВЭД: 62.0) во время создания программ для ЭВМ. Методологической базой исследования послужили теория управления проектами, в том числе и в области ИТ. Методы исследования – анализ национальных стандартов и анализ судебной практики ИТ-субъектов. На основании проведенного исследования было установлено, что ИТ-продукт является объектом, который может быть ИТ-услугой либо совокупностью ИТ-результатов, полученных по завершению спринтов, фаз жизненного цикла ИТ-проекта и (или) контракта. Анализ 192 судебных решений и бизнес-деятельности 495 ИТ-субъектов Томской области показал, что предлагаемое автором настоящей статьи уточнение универсально и может без комплаенс-последствий заменять понятия, которые характеризуют ИТ-объекты. Кроме того, уточненная формация понятия также указывает на необходимость учета ряда комплаенс-особенностей создания ИТ-продуктов в рамках выполнения ИТ-проектов. В частности, на необходимость документального оформления перехода прав собственности на ИТ-продукт, отчуждение либо переход исключительных прав на созданный результат интеллектуальной деятельности от одного субъекта к другому субъекту и др.

Unveiling Disparities: Exploring Overmedication of Black Foster Care Youth and How Implicit Bias Contributes
Authors: Edwards Janice Berry , Selas Adachi
Published: October 2024

Background:Black youth are overrepresented in the foster care system, and research is needed to reveal the impact of their overmedication (Cénat et al., 2021; Dettlaff & Boyd, 2020; Godoy et al., 2022; Lee et al., 2015; Montgomery, 2022; Williams-Butler, 2023).

Objective:This article examines misdiagnoses, overprescribed psychotropics, and off-label medication use to address behavioral concerns (American Civil Liberties Union Maryland v. Maryland, 2023; Cullins & Moore, 2020; Fadus et al., 2020; Mizock & Harkins, 2011) and investigate the contribution of implicit bias to find equitable and nondiscriminatory solutions.

Methods:A systematic literature review was conducted to identify themes surrounding racial disparities within the child welfare system. Articles that were published within the last five years were prioritized, except for those with unique findings or a specific lens of inquiry. Foundational references such as relevant legislation were also used to support the research questions.

Findings:The literature reveals significant and clear disparities in the treatment of Black youth within the child welfare system. Black foster care youth are often medicated at disproportionately high rates.

Conclusions:The findings suggest that more culturally intelligent interventions are necessary to ensure Black foster care youth receive adequate and appropriate assessment and treatment.
College Students’ Coercive Sexting and Intimate Partner Violence Perpetration in Shorter- and Longer-Term Relationships

Published: October 2024

This study examines the moderating role of relationship length on the association between coercive sexting and intimate partner violence (IPV) perpetration. Research has supported a positive association between coercive sexting and IPV perpetration ( Drouin et al., 2015), though no prior research has examined how relationship length moderates this association. To test this relationship, we administered a multipart questionnaire online to 798 undergraduate participants (79% White, 77% female,Mage= 19.1 years) currently in a relationship. We assessed physical, psychological, and sexual IPV perpetration. Relationship length moderated the link between coercive sexting and sexual IPV perpetration. More specifically, the association was stronger in longer-term compared to shorter-term relationships. These results carry implications for future research and IPV education and intervention programs, suggesting that they should incorporate coercive sexting into their curriculums and target newer couples.

Bu amaçla beliren yetişkinlik döneminde olan üniversite öğrencilerinde sosyal medya bağımlılığı, bağlanma ve zihin okuma arasındaki ilişkiler incelenmiştir. Araştırmaya 129 üniversite öğrencisi (93 kadın, 36 erkek) katılmıştır. Sosyal medya bağımlılığının belirlenmesinde Bergen Sosyal Medya Bağımlılığı Ölçeği, zihin okuma becerilerinin değerlendirilmesinde Gözlerden Zihin Okuma Testi, akran ve ebeveynlerine bağlanmalarının ölçülmesinde ise Ebeveyn ve Arkadaşlara Bağlanma Envanteri - Kısa Formu kullanılmıştır. Öncelikle değişkenlerdeki cinsiyet farklıklıkları ve değişkenler arasındaki ilişkiler incelenmiştir. Ardından yüksek sosyal medya bağımlılığı olanlar ile olmayanlar arasında bağlanma ve zihin okuma açısından anlamlı bir farklılık olup olmadığı analiz edilmiştir. Bulgular sosyal medya bağımlılığının kadınlarda daha yüksek olduğunu ve arkadaşa bağlanma arttıkça, sosyal medya bağımlılığının azaldığını göstermiştir. Yüksek sosyal medya bağımlılığı olanların, diğerlerine göre ebeveyne bağlanma ve arkadaşa bağlanma puanlarının anlamlı olarak daha düşük olduğu bulunmuştur. Zihin okuma becerileri açısından ise sosyal medyaya bağımlılığı yüksek olanlar ile olmayanlar arasında anlamlı bir fark yoktur. Bu bulgular sosyal medya bağımlılığının önlenmesinde ebeveyn ve akran ilişkilerinin koruyucu bir rol oynayabileceğine işaret etmektedir.

Az ipolytölgyesi duzzasztó a Duna felől az első műtárgy, amely nehezíti a halak hosszirányú átjárhatóságát. Kutatásunkban a duzzasztómű alatti folyószakasz halfaunáját vizsgáltuk egyetlen alkalommal, 2023. szeptember 11-én, a kora őszre jellemző alacsony vízállásnál. Összesen 25 hal- és egy tízlábú rákfajt (cifrarák, Faxonius limosus) mutattunk ki. Az Ipoly alsó szakaszán Ipolytölgyesről korábban szakcikkekben közölt adatokhoz képest újszerű észlelésnek számít a védett széles durbincs, és megerősítő észlelésnek a fokozottan védett német bucó és magyar bucó előkerülése. A fogott halak nagy része a 0+ és juvenilis korosztályhoz tartozott, különösen a márna ivadéka volt jelen nagy számban. Ez azt jelzi, hogy az ipolytölgyesi folyószakasz értékes szaporodóhely és ivadékbölcső is egyben nem csak az Ipolyban élő, hanem a dunai halpopulációk számára is.

Introdução: As artes marciais, praticadas pelas mulheres, no Brasil, foram controladas desde a década de 1940. O Decreto-Lei n° 3199/41, proibia a participação oficial de mulheres em determinadas práticas consideradas inapropriadas e prejudiciais à natureza de seu sexo, e que incluía as lutas de qualquer natureza. Tal fato, impôs as inserções tardias das mulheres na prática do Karatê. Objetivos: A presente pesquisa, buscou identificar que discursos emergem e atravessam, a prática do karatê feminino, bem como, o impacto da maternidade sobre a permanecia no esporte. Metodologia: Utilizamos a história oral temática para recolha das narrativas das atletas feminina do karatê montes-clarense. Para análise das fontes orais, aplicamos a Análise do discurso, buscando identificar a condição de produção, seus interdiscursos e o contexto do discurso, que permeiam a prática do karatê. Resultados e discussão: A trajetória esportiva das karatecas montes-clarenses, foram impactadas pela ocorrência da maternidade que, resultou no abandono ou prejuízo no desenvolvimento da carreira esportiva. Considerações Finais: Para as mulheres, a prática de artes marciais, continuam sendo atravessadas por discursos baseados no determinismo biológicos e nos papeis sociais determinados para as mulheres ligados a um ideal social de ser feminina e ser mãe.

Published: October 2024

Chronic non- infectious diseases represent an important medical and social problem for the healthcare system. Optimal pharmacotherapy is not always effective enough, and the use of surgical treatment methods is not possible in all patients. In addition, an important link in the comprehensive management of such patients is dosed physical activity, however, in most of them, low exercise tolerance does not allow them to exercise, starting a vicious circle that leads to a decrease in the functional reserve of the body. In this case, the use of non-pharmacological treatment methods, for example, enhanced external counterpulsation, may be useful. This review is devoted to the analysis of literature data on the possibilities of using this method, which is important in clinical practice.

Objectives. To evaluate the informativeness of the N-terminal brain-promoting natriuretic peptide (NT-proBNP) for the diagnosis of chronic heart failure (CHF), depending on the presence of senile asthenia syndrome (SSA) in patients with arterial hypertension (AH) 80 years and older.

Materials and Methods. 320 patients with hypertension, depending on the presence of CHF and SSA, were divided into groups: group 1A — patients with hypertension, SSA and CHF (n=84), group 1B — patients with hypertension, SSA without CHF (n=77), group 2A — patients with hypertension, CHF without SSA (n=84), group 2B — patients with hypertension without CHF and without SSA (n=75). The CSA was identified by the questionnaire “Age is not a hindrance”. The level of NT-proBNP was determined in blood serum by enzyme immunoassay. ROC analysis was used to determine the threshold value of markers.

Results. In patients with hypertension and SSA without CHF, the concentration of NT-proBNP in the blood is 2.3 times higher (p=0.003) compared with patients with hypertension without SSA and without CHF, which indicates the effect of SSA on the level of NT-proBNP. In patients with hypertension and CHF without SSA, the level of NT-proBNP is 4.3 times higher compared with patients with hypertension without SSA and without CHF (p<0.001), in whom the concentration of NT-proBNP was noted below the threshold level (106.2 pg/ml). In patients with hypertension and SSA and CHF, the highest concentrations of NT-proBNP were recorded, which are 2.9 times (p<0.001) higher than in “fragile” patients with hypertension without CHF and 1.5 times higher than in “strong” patients with hypertension and CHF (p<0.001). A new threshold level of NT-proBNP has been calculated for the diagnosis of CHF in patients with hypertension and SSA aged 80 years and older — 365.9 pg/ml.

Conclusion. For the diagnosis of CHF in patients with hypertension 80 years and older without CSA, the NT-proBNP marker is informative, since, according to the data obtained, its level did not depend on the age of the patients. When using NT-proBNP to detect CHF in patients with hypertension and SSA 80 years and older, the calculated threshold marker level (365.9 pg/ml) should be used, since in these patients the concentration of NT-proBNP is increased, regardless of the presence of CHF.

Kidney injury in patients infected with the human immunodeficiency virus (HIV) has a diverse spectrum. Some antiretroviral therapy (ART) drugs have nephrotoxic effects. We present a clinical case of severe combined kidney injury — chronic kidney disease (CKD) and acute kidney disease (AKD) — in a patient with HIV infection. She was on long-term treatment with a fixed-dose combination of rilpivirine, tenofovir, and emtricitabine and had normal pre-treatment renal function (estimated glomerular filtration rate 69 mL/min/1.73m2 ). There was gradual increase in blood creatinine, but the patient did not visit a nephrologist and the ART was not changed. The patient was admitted to the nephrology department two years later because she had arterial hypertension and hyperazotemia (blood creatinine 718 μmol/l). Diagnosis: chronic tubulointerstitial nephritis, CKD G5 taking into account the gradual increase in blood creatinine during long-term ART. The patient was treated with peritoneal dialysis. There was persistent decrease and stabilization of blood creatinine (210-190 μmol/l was) which indicated in AKD. The presented observation demonstrates that ART in an HIVinfected patient can lead to the development of severe combined chronic and acute kidney injury. HIV-infected patients receiving ART require regular monitoring of renal function and follow-up by a nephrologist.

This qualitative study intentionally gathered insights from 12 educators of varying seniority across three schools in the Nkangala Education District, Mpumalanga Province, South Africa, regarding their experiences with mobile learning (facilitated through Microsoft Teams and WhatsApp Messenger) as a professional development and knowledge retention tool during the Covid-19 pandemic. The findings, derived from semi-structured interviews and document analysis, indicated that young educators positively embraced the implementation of Microsoft Teams and WhatsApp Messenger. Senior educators deemed WhatsApp Messenger less intimidating than Microsoft Teams, thereby endorsing it as the preferred medium for professional growth and knowledge retention. This led to a lack of incentive among senior educators to participate in the professional learning events facilitated by Microsoft Teams. Thus, they depended on the supplemental learning information disseminated via WhatsApp Messenger as the principal method for professional development and knowledge retention activities. The research identified multiple obstacles to utilising mobile learning for professional development and knowledge retention, specifically: insufficient ICT skills among senior educators, ineffective content facilitation by subject advisors, and inadequate communication and scheduling of professional development programs. The study advocated for a systematic coordination of: 1) a series of ICT skills training for underqualified educators; 2) peer teaching among novice, mid-career, and senior educators to address internal skills deficiencies; 3) effective communication among the district, circuits, and schools; and 4) skills audits for subject advisors to enhance competency in areas of deficiency. By presenting these recommendations, the report alerts schools, circuits, and districts to the likelihood that the Covid-19-induced adoption of hybrid professional development will become the standard practice.

The COVID-19 pandemic necessitated significant adjustments across various sectors globally, and the education sector was no exception. To adhere to social distancing requirements and ensure continuity in education, E-learning emerged as a viable solution, offering a glimmer of hope in these challenging times. However, this strategy brought its own set of challenges. This study aimed to explore the experiences of students with E-learning, particularly focusing on the obstacles and benefits encountered. A qualitative approach was employed, utilizing an exploratory research design to gather comprehensive insights. Participants were selected through purposive sampling, focusing on five University of Venda students registered for the 2021 academic year. Data collection was conducted via one-to-one semi-structured interviews, which allowed for detailed and nuanced responses. Thematic analysis was used to analyse the collected data, identifying key themes and patterns in the students' experiences. The findings highlighted various challenges, such as limited access to reliable internet, lack of digital devices, and difficulties in maintaining motivation and engagement in a virtual learning environment. Despite these challenges, some students appreciated the flexibility and convenience offered by E-learning, highlighting its potential. The study underscores the need for improved infrastructure and support systems to enhance the E-learning experience. These insights can inform policymakers and educational institutions in developing more effective strategies to support students in a digital learning landscape, ensuring that the benefits of E-learning are maximized while minimizing its drawbacks. The findings contribute to the broader discourse on the adaptation of education systems in response to global crises, emphasizing the importance of resilience and adaptability in educational practices.

Published: October 2024

The prevalence of mental health illness is on the rise throughout the world. Mental health is increasingly one of the most overwhelming conditions that has an effect on the social functioning of individuals and families within communities. Mental Health Care Act, No 17 of 2002 of the South African government provides for the protection of individuals and communities against mental health. Still, people continue to experience mental health problems at a high rate. Social workers have a fundamental role to play in improving mental health services and outcomes for communities. Social work services have the potential to improve the lives of people with mental health conditions and build resilience in individuals and families. Resilience is a critical technique that assists individuals to function properly despite the challenges they may have experienced.  Research has shown that people with mental health problems struggle to return back to normality. This article aims to explore the roles of social work intervention in promoting mental health and resilience in communities. The study was conducted by analyzing research or studies related to mental health and resilience. The study carried out comprehensive desktop electronic research to gather data and themes from previous studies. The analysis showed that mental health is still a major concern, and social workers have an important role to play in building resilience for individuals and families.
The impact of climate change on banks loan portfolios and strategies for effective climate risk management
Authors: Muzuva Meshel , Muzuva Daniel
Published: October 2024

As extreme weather events continue to impact every continent and the world moves towards establishing a lower-carbon economy, the banking industry is expected to incorporate climate risk into their risk management practices. Climate change poses significant risks to bank loan portfolios through increased physical and transition risks. This study systematically analysed the literature to identify effective strategies for managing these risks. Our findings reveal that climate-related events can lead to substantial loan defaults and credit losses. To mitigate these impacts, banks can integrate climate risk into their risk management frameworks, adopt sustainable lending practices, and diversify their portfolios. Some banks have already implemented measures to mitigate climate risk through insurance policies, while others are incorporating sustainability criteria into their lending practices, such as financing green projects. By proactively addressing climate risks, banks can protect their portfolios, enhance financial resilience and contribute to a low-carbon economy.

The purpose of this study is to examine and analyze law politics related to the execution of bankruptcy decisions against debtor assets abroad. The research method used is normative legal research with a qualitative descriptive analysis method approach, based on comparative law, with prescriptive analytical specifications. The research findings conclude that sovereignty is interpreted as the responsibility to improve and protect all national and international community interests, manifested in the form of the state's ability to interact and establish relations with countries in the world, as well as cooperate and coordinate bilaterally, multilaterally and in international organizations. The provisions on international bankruptcy in Law of the Republic of Indonesia Number 37 of 2004 concerning Bankruptcy and Suspension of Debt Payment Obligations or Undang-Undang Republik Indonesia Nomor 37 Tahun 2004 tentang Kepailitan dan Penundaan Kewajiban Pembayaran Utang (Bankruptcy Law) are similar to the Dutch Bankruptcy Law, there are no comprehensive regulations related to international bankruptcy. To ensure legal certainty, a legal policy is needed in the form of changes and updates to the Bankruptcy Law by adding articles to apply the principles of international bankruptcy in the Model Law, namely the Principle of Access, the Principle of Recognition, the Principle of Assistance and the Principle of Cooperation and Coordination, as applied in the US Bankruptcy Code Chapter 15. Article 299 of the Bankruptcy Law also needs to be amended so that the procedural law applied is the special procedural law for international bankruptcy.
The secret to fixing incorrect canonical quantizations
Authors: Klauder John R. , Fantoni Riccardo
Published: October 2024

Covariant scalar field quantizations will be called (φr)n, where r denotes the power of the interaction term and n = s + 1, where s is the spatial dimension and 1 adds time. Models where r < 2n/(n − 2) can be treated by canonical quantization, while models where r > 2n/(n−2) are trivial or, if treated as a unit, emerge as ‘free theories’. Moreover, according to canonical quantization, models where r = 2n/(n−2), e.g., r = n = 4, also become ‘free theories’, which must be considered quantum failures. However, there exists a different approach called affine quantization. This approach promotes a different set of classical variables to become the basic quantum operators and offers different results. It is well known that the canonical quantization of φ44 fails. This article addresses this failure alongside solutions to other problems.
