The paper substantiates the relevance of studying powder metallurgy methods and efficiency of applying them to the production of spherical bearings of highly loaded spherical hinge joints. It proves that the force and work of deformation, as well as the kinetics of forming of the outer cage of a spherical hinge joint made of sintered corrosion-resistant chromium-nickel steels, are influenced by the chemical composition of powders and lubricants, the protective environment and the method of sintering, the microstructure and mechanical properties of the workpiece material. It is shown that the plastic properties of ring specimens under testing depend on the perfection of interparticle contacts, the presence and distribution of chromium oxides, forming schemes and workpiece porosity. The influence of the method for the production of stainless chromium-nickel powders on the density and mechanical properties of the sintered blanks is studied. A method is proposed for evaluating the strain state during radial deformation of ring specimens made of these steel powders and estimating the maximum allowable values of strain intensity below which no cracks are formed during cold forming of porous blanks. It is revealed that, to calculate the stress state and, accordingly, strain resistance in the cold forming of the outer cages of spherical hinge joints, made of sintered corrosion-resistant steels, it is possible to use the known constitutive equations if strain intensity does not exceed the experimentally obtained limit values. The feasibility of implementing the proposed method and selecting the process parameters of cold forming of spherical hinge parts made of chromium-nickel austenitic steels is substantiated.
Realidade, ficção e utopia: uma primeira tentativa de dissolução de fronteiras
Authors: Drummond Ana Luíza Duarte de Brito
Published: December 2024

Este trabalho realiza um levantamento básico sobre as discussões que envolvem as fronteiras entre realidade e ficção e se estica para pensar também essa fronteira em seu alongamento até a utopia. Iniciamos por Adorno para discutir com Costa Lima, Jeremy Bentham, Hans Vaihinger e Wolfgang Iser os conceitos de realidade e ficção, além da ideia de imaginário deste último. A partir deles, chegamos a Victor Chklóvski, Fredric Jameson e Marilena Chauí para expor como a barreira criada entre a realidade e a ficção atinge também a utopia. Nosso intuito aqui é expor essa discussão e fazer alguns levantamentos para pensar, futuramente, como e por que a crítica de arte, durante boa parte do século passado e do século XIX, empenhou-se em separar com barreiras bastante expressivas a realidade da ficção e da utopia.
Crônica de aulas sobre a crônica
Authors: Belúzio Rafael Fava
Published: December 2024

Ao correr da tecla, meio ensaio acadêmico, meio crônica de professor, aqui se procura refletir a respeito do gênero crônica e do seu ensino. Relatando experiências docentes ocorridas em uma escola federal de Ensino Médio, são discutidas algumas aulas sobre crônica e são problematizados – teoricamente e levando em conta posicionamentos dos alunos – supostos aspectos constitutivos desse “gênero menor”: o registro do circunstancial, a limitação ao jornal, a efemeridade, o público limitado, a limitação ideológica, a limitação de espaço, o pouco tempo de elaboração, o sujeito-textual ser igual ao sujeito-real, a pouca densidade e a oralidade.
Men haunted and defined by the past in The Shining and Long Day’s Journey into Night
Authors: Santos Diego Moraes Malachias Silva
Published: December 2024

Despite apparent differences, there are several parallels in the treatment of tradition and masculinity in Eugene O’Neill’s Long Day’s Journey into Night and Stephen King’s The Shining. In this article I suggest comparative approaches between those two works, which, in their core, narrate a man’s flawed attempt at reinstituting a traditional form of masculinity by revisiting and being revisited by the past. Their depiction of masculinities indicates a similar criticism of American traditional manhood and suggests that Stephen King, especially in his earlier novels, combined Naturalistic and Gothic approaches to help redesign modern horror, bringing it to the heart of American culture.
Luciano de Samósata e a ficção da tradição democrática
Authors: Cardoso Igor B.
Published: December 2024

Mais que um polemista do século II, Luciano de Samósata expressou importantes transformações da consciência histórica de seu tempo. Procura-se argumentar que os usos e abusos da terminologia democrática grega, especialmente a ateniense, em uma conjuntura política na qual Roma estendeu seu imperium por todo o Mediterrâneo, indicam uma fratura entre o antes e o agora. Com efeito, ao contrário do período clássico, quando os historiadores procuravam fazer do passado recente uma fonte que iluminaria os caminhos a serem tomados no futuro, no século II era reconhecida a artificialização da continuidade temporal, que facultava ora naturalizar o processo de dominação ora colocar o passado em disputa. Para tanto, serão cotejadas diferentes obras de Luciano, a exemplo de Como se deve escrever a história, Das narrativas verdadeiras e Nigrino, com outras de personagens do mesmo período, como do imperador Marco Aurélio e do apologista Élio Aristides.

Football, Art and Resistance: A dialogical reading of football as art and emancipation
Authors: Bedoya Cortés Sergio
Published: December 2024

This work focuses on analysing aesthetic-sporting phenomena from a political perspective. To do so, it uses approaches from Marxism and critical theory, in principle, to elucidate the relationship between sporting act and aesthetic fact so that, later, the micro-practices of sports can be analysed from the French critical thought of G. Deleuze as phenomena of resistance (cultural or not) of the sporting activity. The analysis presented here attempts to correlate a philosophical conceptual approach, a historical sociological account of sports practices and facts, as well as a journalistic collection of eventualities and characters that outline, from their mere daily practices, exercises of resistance to the alienation of capital represented both in sport and in the culture that passes through (their) bodies generating beauty and Thanatos.
Evaluation of Person-Centered Dementia Care Utilizing the CARES® Observational Tool
Authors: Cattoor Erin , Hobday John
Published: December 2024

The training of staff in residential long-term care facilities, such as nursing homes and assisted living facilities, is increasingly being conducted via asynchronous, online training platforms. Even when organizations have in-person trainers to conduct synchronous training on-site or via online video tele-conferencing formats, a paucity of research has evaluated how training in any form affects staff members’ actual, observable, person-centered care practices, particularly when working with individuals living with Alzheimer’s disease or other related dementias (ADRD).

This study sought to fill this gap by evaluating the impact of the two CARES® online dementia care training programs on staff members’ observable care practices, as measured by the CARES® Observational Tool (COT), a previously published person-centered observational tool.1 The study hypothesized that staff completion of the two CARES® online training programs would not only result in increased knowledge of ADRD and person-centered care practices within long-term care facilities, but also lead to an observable increase in the use of person-centered care practices, as measured by the COT. A single group pre-test/post-test design was used, which included a baseline, immediate post-test, and one-month post-test data collection interval among the entire staff of a memory care unit (N = 26) at a nursing home in a large Midwestern city in the United States. The results showed statistically significant increases in both ADRD knowledge (p < .0001) and observable person-centered care (p < .0001). The CARES® online training programs and the COT seem to offer a promising solution to address the ongoing and expanding gaps in delivering and demonstrating effective person-centered care to people living with dementia (PLWD) in residential long-term care.
Restricting the number of drug options that can be used to treat a disease results in unsatisfactory outcomes for patients, prescribers and payers alike.
Authors: Walker David , Robinson Sandra
Published: December 2024

Developing new drugs is extremely expensive often costing upwards of a billion dollars to bring a drug to market1. This is driven by the studies required to demonstrate the safety of the drug and bears little relation to the cost of manufacture. Demonstration of efficacy generally requires much smaller numbers. The level of safety required is, quite rightly, stringent, and is to give confidence that unexpected side effects are unlikely to be found when the drug is released for use in the general population. If a lower level of safety was accepted, then drugs could be considerably cheaper, but at a risk. However, the study patients are selected, usually for having active disease and few other conditions to complicate response. It is estimated that only about 30% of patients seen in clinic are suitable for any particular study2 so we can’t know for sure what will happen when it is available to the other 70%. This is a weakness of the evidence base3.

Drugs are licensed on a risk benefit analysis by the drug regulators eg the MHRA. More recently, driven by the expense of new drugs, in the UK, before they can be used they have been required to show cost effectiveness through a National Institute for Clinical Excellence (NICE) assessment where the cost of the improvement in quality of life needs to hit an acceptable threshold4. There is often press and political interest in these approvals. The aim of NICE is to ensure value for money and equality of access to drugs, abolishing postcode prescribing where different geographical areas have different access to drugs. However, the Clinical Commissioning Groups (CCGs) who pay for the drugs, may have their own interpretation of guidelines, and NICE approvals, which apply in their area. An example of this was a restriction on the number of higher cost drugs (HCDs Biologics and JAKi) that could be tried for RA by a substantial number of CCGs in England5,6.

At a session of the BSR annual meeting in 2019 discussing what Rheumatologists do when the patient in front of them doesn’t fit the guideline for a treatment that they think will be effective, it became apparent that a substantial number of rheumatology services were restricted by their CCGs7. Those of us from unrestricted areas were surprised and could not understand the logic for this restriction. The main reason discussed was that these drugs had not been shown to be cost-effective at higher choice points. That was, of course, true but only because the studies had not been done, another weakness of the evidence base3. Lack of evidence is not evidence of lack of effect.
Factors of the arterial hypertension formation as a phenotype of metabolic syndrome in perimenopause
Authors: Ruyatkina L. A. , Ruyatkin D. S. , Shcherbakova L. V.
Published: December 2024

Introduction. Menopause as a potential risk factor for insulin resistance and associated metabolic and hemodynamic disorders determines the need to study the formation of the perimenopausal metabolic syndrome (MetS) phenotype with arterial hypertension (AH).

Objective: to assess correlations between MetS markers and characteristics of the menopausal transition with their role in hypertension based on the analysis of a perimenopausal normoglycemic cohort.

Patients and methods. Of the 88 women aged 35–59 years, 58 women had hypertension and 30 were normotensive. The following were determined: waist circumference (WC), blood pressure (BP), triglyceride (TG), HDL-C, insulin, follicle-stimulating hormone (FSH), estradiol and glucose levels, TyG, HOMA2-IR indices. The following were estimated (SPSS, version 17): median (25; 75%); intergroup differences according to the Mann-Whitney criterion; comparison of proportions according to Pearson's χ2; Spearman's correlation (R) and partial correlation (Rрс) analyses were performed to level out the influence of age; binary logistic regression was used to identify prognostic factors.

Results. The TyG index correlated age-dependently with FSH (R=0.211; p=0.048) and estradiol (R= -0.262; p=0.014), and age independently with BP, WC, and HDL-C. The associations of WC with BP that are relevant in partial correlation are the closest with TyG (R=0.526 and Rpc=0.424; p<0.001) and HOMA2-IR (R=0.507 and Rpc=0.370; p<0.001), age is dependent on HDL-C, duration of postmenopause and estradiol (R= -0.313; p=0.003). According to the stepwise multiple logistic regression analysis, with an increase in WC by 1 cm, the chance of having hypertension increases by 9%; with an increase in the TyG index by 1 conventional unit - by 16 times.

Conclusion. The ascending hormonal and metabolic trajectory of the components of metabolic syndrome in perimenopause with the central pathogenetic link of insulin resistance emphasizes the importance of factors specific to women and attention to arterial hypertension with its leading role in the cluster.
Cancer mortality in the USA and atmospheric nuclear weapons test fallout ratio. Identifying the principal origin of the global cancer epidemic
Authors: Busby Christopher
Published: December 2024

Recent advances in epidemiological analysis of the effects of radioactive contamination have raised questions over the security of current radiation risk models. One outstanding question relates to the effects of atmospheric nuclear weapons tests and the fallout which peaked in 1959-63. Effects on cancer, a late genetic disease, are investigated here by employing a metric R which divides the rate in high fallout and low fallout States of the USA. An allocation of the two groups is based on rainfall and supported by measurements of Strontium-90 in baby teeth. Results from comparing cancer mortality in Whites for High fallout States AR/KY/LA/MS and TN with low fallout States AZ/CA/ NM reveals a highly significant fallout cohort effect peaking in those born in 1955-1964 in all 10-year birth cohort age groups. The ratio was calculated for 10-year groups for deaths in 1969, 1979, 1989, 1999, 2009 and 2019. Cancer mortality ratio effects increased with age. In the oldest 10-year group studied, 55-64, in 2019 the Excess Risk for those born in 1955-64 was 52% greater in the high fallout regions ERR =1.52; 95% CI 1.48, 1.57; p <0.00000000. For the 45-54 group in 2019 ERR = 1.42; 95% CI 1.35, 1.50; p < 0.00000000. For the 34-45 ERR = 1.27; 95% CI 1.15, 1.40; p<0.000001. Arguably the results identify the main cause of the cancer epidemic which began in the 1980s.
Epidemiological profile of human papillomavirus infections and cervical cancer prevention among sexually active women in Burkina Faso: Literature Review
Authors: Zabre Pierre , Sagna Tani , Ouedraogo Rogomenoma , Simpore Jacques
Published: December 2024

Cervical cancer is one of the biggest public health challenges in developing countries. According to the Global Cancer Observation in 2022, Burkina Faso recorded 988 new cases, with 775 deaths. Caused mainly by the human papillomavirus (HPV), this cancer is a heavy burden on our populations. The aim of this review was to assess the current state of human papillomavirus infections and cervical cancer prevention among sexually active women in Burkina Faso. Original studies were extracted from PubMed/Medline, Google Scholar, semanticscholar, Hinari and Science Direct using appropriate MeSH terms. Results were extracted and reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyse method (PRISMA). Twenty-four studies from three regions of Burkina Faso were included in the systematic review, with most of the articles from the “Centre” region. Out of a total of 5480 participants for the pooled analyses, the review showed a prevalence of HPV, varying according to population type and region and ranging from 20.6% to 87.2%. In contrast, the overall prevalence of HPV 16 and 18 infections were low compared to the global trend. With a low screening rate, the prevalence of cancerous lesions ranged from 1.5% to 15.42%. The level of knowledge was lower among rural than urban residents. Bivalent and quadrivalent vaccines had low coverage for the genotypes identified. In the fight against cervical cancer in Burkina, concerted efforts are needed to strengthen screening programs, increase HPV vaccination coverage, and raise public awareness. Large-scale national studies are needed to map HPV genotypes in order to make appropriate decisions for cervical cancer control.
Symptoms of digital addiction of Estonian primary school students
Authors: Seema Riin , Väljas Johanna , Oppi Piret
Published: December 2024

The goal of the present work was to map Estonian primary school students' ratings of symptoms of digital addiction and to determine both class and gender differences. The sample included 5493 primary school pupils from 46 schools in Estonia participating in the 2022 Student Survey conducted by the Centre for Educational Innovation at Tallinn University. The results indicated that the digital addiction symptoms scores were highest among 8th and 9th graders. Girls and those students who did not disclose their gender, scored higher than boys on digital addiction symptom statements. Symptoms of digital addiction showed a moderate positive correlation with screen time on both school days and weekends, as well as with school burnout. There was a weak negative correlation between digital addiction symptoms and feeling refreshed in the morning. Since only a relatively small group of students showed a few symptoms of digital addiction and maintained a healthy pattern of using digital devices, policymakers need to develop digital addiction prevention measures or programs within the educational system.

Inclusión educativa y trastorno del espectro del autismo
Authors: Vidal Esteve María Isabel
Published: December 2024

La atención a la diversidad y el abordaje al tema de la inclusión escolar son preocupaciones fundamentales en el sistema educativo actual. Esta investigación recoge algunos de los principales resultados de una tesis doctoral que enfocada en el análisis de la inclusión educativa del alumnado con Trastorno del Espectro del Autismo (TEA) de los cursos de quinto y sexto de Educación Primaria en cuatro centros públicos de distinta tipología sociogeográfica de la provincia de Valencia. Utilizando un enfoque cualitativo basado en la etnografía y el estudio de casos, se emplearon diversas técnicas de recopilación de datos, como la observación directa, las entrevistas semiestructuradas al alumnado y al profesorado, los test sociométricos y el análisis de contenido, para profundizar en los facilitadores organizativos y didácticos empleados para contribuir a la inclusión en las aulas. Los resultados evidencian múltiples estrategias relevantes como la distribución cooperativa, la flexibilización de tiempos y espacios, el uso de materiales visuales y diversos, la evaluación centrada en las necesidades y la importancia de la actitud docente. Aun así, los enfoques son demasiado básicos y tradicionales, debido a las carencias formativas, la falta de sensibilización docente sobre la inclusión y el TEA, los apoyos individualizados, la escasa colaboración docente y la limitada participación de toda la comunidad en el proceso educativo, aspectos en los que es imprescindible seguir profundizando. A pesar de los desafíos, el contexto rural se presenta como el más propicio para la inclusión, debido a su tamaño, ambiente menos bullicioso, estrategias más personalizadas y conexión con el entorno.

La fotovoz es una técnica que facilita la expresión de la información a través de la toma de imágenes y su correspondiente análisis para extraer su significado. El presente estudio comprende un proceso de investigación inclusiva desarrollado por estudiantes con Discapacidad Intelectual y del Desarrollo (DID) dentro de un programa formativo denominado Investiguem, un programa donde los estudiantes aprenden a investigar dentro de un proceso de investigación inclusiva llevado a cabo en un curso de educación inclusiva postsecundaria en la Universidad Jaume I de Castellón. El objetivo de este estudio es analizar cómo el uso de la fotovoz favorece la participación y el aprendizaje de todo el alumnado en un proceso de investigación inclusiva y detectar los elementos facilitadores y limitadores de su puesta en práctica y del desarrollo del proceso. Metodológicamente se trata de un estudio exploratorio realizado mediante un proceso de observación sistemática no participante y grupos focales conformados por estudiantes e investigadoras. Los resultados indican que la técnica de la fotovoz favorece la participación y el aprendizaje de todas las personas al permitir diferentes posibilidades de comunicación y expresión, además de desarrollar un sentimiento de pertenencia durante todo el proceso. Realizar una planificación desde un marco de diseño universal del aprendizaje se considera como un elemento facilitador. Sin embargo, se han detectado factores limitadores relacionados directamente con el proceso y no con la técnica, relacionados, por ejemplo, con los procesos de análisis y selección de la información. De las conclusiones del estudio, se realizan recomendaciones para futuras puestas en práctica, teniendo en cuenta los facilitadores detectados y transformar los limitadores encontrados para así, fomentar más el empoderamiento del estudiantado a través del uso de la técnica dentro de un proceso de investigación inclusiva.
Nanotechnology in prosthodontics – Small particles big impact
Authors: Kanodia Shruti , Saxena Deepesh , Trivedi Anshul
Published: December 2024

Nearly every aspect of research and development has been significantly impacted by nanotechnology. Notably, nanotechnology is also having an impact on the fields of health and dentistry by utilising its enormous potential. When compared to bulk material, nanoparticles have proven to be far more powerful. Because of its unusual size, it is much easier to change and improve a variety of features, including surface chemistry, charge, bonding ability, and different biological properties. Richard P. Feynman, a late Nobel Prize-winning physicist, developed the idea in 1959. The area was researched in the years that followed for the creation of nanoscale devices and nanosized particles to produce improved qualities. Regularly used dental materials with limitations of inferior physical and biologic qualities can be changed with nanoparticles to improve the material's inherent properties while staying within budgetary constraints. Unique qualities of a nanoscale material may not only have a significant impact on its biological properties, such as cytotoxicity and biocompatibility, but also on its physical properties, such as tensile strength, fracture resistance, and surface hydrophobicity.
Evaluation and comparison of the antimicrobial efficacy of three commercially available denture cleansing agents against different microorganisms: An in vitro study
Authors: Deshpande Saee , Salkar Rashmi , Rathi Akhil , Pande Neelam , Goverdhan Radha , Deshmukh Kalyani
Published: December 2024

Heat cured poly methyl methacrylate denture base acrylic resins are most commonly used material for fabrication of complete dentures. In certain situations, denture hygiene is compromised both due to the constraints of the denture material and/or non-compliance from the patients owing to lack of manual dexterity. This leads to formation of microbial biofilm on the intaglio surface of the denture and if left untreated, it can cause denture stomatitis. Denture cleansing tablets are of great help in such cases.

The primary goal of this in vitro experiment was to assess and compare the effects of commercially available and common household denture cleansing tablets viz. Polident, Fittydent and Clinsodent against Staphylococcus aureus, Streptococcus mutans and Candida albicans

A total of 100 heat polymerized acrylic resin samples were divided into 4 groups of 25 each to evaluate the antimicrobial effectiveness of commercially available denture cleansing agents.

The results of this study showed that there was significant reduction in colony forming units in three commercially available denture cleansing agents (Clinsodent, Fittydent and Polident denture cleansing tablets) as compared to distilled water.

All three commercially available denture cleansing agents used in the study were capable of reducing the colony forming units per ml of the heat cure acrylic resin denture base samples. The order of efficacy was Clinsodent tablets > Fittydent tablets > Polident tablets > Distilled water.
CBCT evaluation of the shaping characteristics of five different file systems in mesial canals of mandibular first molars – An ex vivo study
Authors: Babu Rohit , Dhingra Anil , Grover Sheetal , Dixit Seema , Singh Anshdeep , Pundir Priya
Published: December 2024

Cone-Beam Computed Tomography (CBCT) has revolutionized endodontic research by providing detailed 3D imaging, crucial for assessing the shaping characteristics of endodontic file systems. In the challenging mesial canals of mandibular first molars, where complex anatomy often complicates treatment, CBCT offers precise evaluation of how different file systems shape these canals. This ex vivo study compares five distinct file systems, analysing their ability to maintain the original canal curvature and ensure effective cleaning. The study aims to identify the most effective file systems, potentially improving clinical outcomes in endodontic therapy.

This ex vivo study compared the shaping characterstics of five Ni-Ti rotary File Systems, File Univesal X7 Edge Endo, Bassilogic ProDesign Logic, Gen Endo Coltene Whaledent Pvt. Ltd., Endo Star E3 Azure Basic, Mani Jizai using Cone Beam Computed Tomography (CBCT).

One hundred extracted human permanent mandibular first molars with mesial root curvature angles ranging from 20-30 degrees were divided into five groups (n=20 each). The teeth were imaged using CBCT with CS9300 equipment, set at 84 kV, 5 mA, and a 10.8-second exposure, achieving a resolution of 90 microns and a slice thickness of 76 microns to obtain a pretreatment outline of the root canals. All scans were reoriented along the x, y, and z axes. Canal transportation and root canal volume were evaluated at 0.0, 1.0, 2.0, 3.0, 4.0, and 5.0 mm intervals. The mean differences in volume and area were analyzed using one-way ANOVA to determine the variance between the five different file groups.

Gen Endo File System did the least modifications in the Canal Area and Volume.

Within the parameters of this study it was concluded that GEN ENDO Files did the least modifications in canal anatomy as compared to other groups.

Published: December 2024

This study investigates the relationship between EEG and different levels of working memory performance in children. A total of two hundred thirty subjects have volunteered for the study. Initially, the students are required to answer psychometric tests to gauge their working memory performance. Based on the scores obtained, the students are then segregated in high, medium, and low working memory performance groups. Resting EEG is recorded from prefrontal cortex and pre-processed for noise removal. Synthetic EEG is then generated to balance out and enhance the number of samples to two hundred for every control group. Next, short-time Fourier transform is applied to convert the signal to spectrogram. The feature image is used to train the VGGNet model. The deep learning model has been successfully developed with 100% accuracy for training, and 85.8% accuracy for validation. These indicate the potential of assessing working memory performance alternatively using EEG and VGGNet model.

On finitely g-supplemented modules
Authors: Nebiyev Celil , Ökten Hasan Hüseyin
Published: December 2024

In this work, some properties of finitely g-supplemented modules are investigated. Let M be a finitely g-supplemented R−module and N be a finitely generated or small submodule of M. Then M∕N is finitely g-supplemented. Let f : M→N be an R-module epimomorphism with small kernel. If M is finitely g-supplemented, then N is also finitely g-supplemented. Let M be a finitely g-supplemented module, RadgM ≤ U ≤ M and U be finitely generated. Then U∕RadgM is a direct summand of M∕RadgM.
On non-oscillation for two dimensional systems of non-linear ordinary differential equations
Authors: Opluštil Zdeněk
Published: December 2024

The paper studies the non-oscillatory properties of two-dimensional systems of non-linear differential equations u′ = g(t)|v|1 α sgnv,v′ = −p(t)|u|αsgnu, where the functions g: [0,+∞[→ [0,+∞[, p: [0,+∞[→ ℝ are locally integrable and α > 0. We are especially interested in the case of ∫ +∞g(s)ds < +∞. In the paper, new non-oscillation criteria are established. Among others, they generalize well-known results for linear systems as well as second order linear and also half-linear differential equations. The criteria presented complement the results of Hartman-Wintner’s type for the system in question.
An inverse time-dependent source problem for a time-fractional diffusion equation with nonlocal boundary conditions
Authors: Mihoubi Farid , Nouiri Brahim
Published: December 2024

In this paper, we investigate an inverse time-dependent source problem for a time-fractional diffusion equation with nonlocal boundary and integral over-determination conditions. The fractional derivative is described in the generalized Caputo sense. The nonlocal boundary conditions are regular but not strongly regular. The special thing about this problem is: the system of eigenfunctions is not complete, but the system of eigen-and associated functions forming a basis in L2 (0,1). Under some natural regularity and consistency conditions on the input data the existence, uniqueness and continuously dependence upon the data of the solution are shown by using the generalized Fourier method, the estimates of Mittag-Leffler function and Banach’s contraction mapping principle.

Authors: Bas Umut , Budak Hüseyin , Kara Hasan
Published: December 2024

In the current investigation, we acquire the upper and lower bounds for inequalities of midpoint-type and trapezoid-type involving conformable fractional integral operators with the help of the mappings whose second derivatives are bounded. We support the established inequalities with examples. Moreover, we use graphs to demonstrate the correctness of the given examples. What’s more, we prove the Hermite-Hadamard inequality, which includes conformable fractional integrals, with the aid of condition f′(a + b − t) − f′(t) ≥ 0, t ∈ [a, a+b 2 ] rather than the convexity of function.

Comparative Analysis of Government Regulatory Compliance: A Case of Kenya, China and USA
Authors: Wakoli Leonard W.
Published: December 2024

The importance of regulatory compliance in ensuring that laws and related public policies accomplish their intended goals, which include promoting social and economic development and protecting important aspects of public welfare in a nation cannot be gainsaid. Championing regulatory compliance is a crucial part of international development work, as much as it is frequently overlooked. Studies reveal that the "volume" and harshness of enforcement do not always correspond with compliance and regulatory outcomes, that compliance is not always the intended result of regulations, and that compliance is not always the automatic consequence of regulations. Robust data also indicates that regulations, regulatory administration, procedures, and systems that are not well-designed can impede economic expansion and serve as a breeding ground for corruption. This study digs into the complexities of government regulation compliance in the ever-evolving field of e-commerce, providing a comparative examination among three very different jurisdictions: Kenya, the United States and China. The purpose of the study is to clarify the constantly changing regulatory environment that oversees Internet commerce by investigating the legal frameworks, enforcement strategies, and commercial ramifications that arise for companies that operate in these various areas. The research endeavors to enable cross-border cooperation and enlighten policymakers on effective regulatory strategies to balance innovation, consumer protection, and industrial growth by identifying commonalities and discrepancies in regulatory approaches. This research offers a contemporary overview of the legislative frameworks driving the digital marketplace in various regions, as e-commerce continues to redefine global trade dynamics.
Resettlement Implementation in Water Projects: A Case of Northern Collector Tunnel Murang'a County
Authors: Mathai Grace , Ndung'u Dr Anthony
Published: December 2024

Large-scale water projects threaten livelihood and disrupt communities due to demand for large tracts of land (Walelign & Lujala, 2022). Despite conducting social impact assessment, water projects carry unexpected twists that extend for years. This paper focused on Murang’a Northern Collector tunnel, Murang’a County in Kenya through an ex-post facto design with descriptive survey analysis. It described the impacts of resettlement restoration efforts in water projects. The total land affected by Phase 1 was about 10.766 acres disrupting around 657 people (World Bank Group, 2019). The study found that the affected persons were dissatisfied with the resettlement process. Stakeholders complained of delayed and insufficient compensation, lack of access to water in the project area, and limited public participation. A sample of 261 respondents was used to draw conclusions. The correlation coefficient for the study was R=0.886 with
P<0.001, F=163.550, and adjusted R2=0.779. This indicated that the regression model was statistically significant and resettlement implementations contribute to variation in project outcomes. In examining the individual variables most of the participants disagreed or strongly disagreed they were satisfied with the process of resettlement. The paper proposed policy change, adequate multi-stakeholder engagement and harmonization of valuation for fair compensation of land acquired during projects and livelihood restoration.
La calidad de la democracia y la violencia en América Latina y Caribe
Authors: Castelo Branco Pedro H. Villas Bôas , Gouvêa Carina Barbosa
Published: December 2024

Las democracias representativas latinoamericanas han sufrido ataques que vienen minando sus estructuras y provocando déficits democráticos. Escándalos de corrupción envolviendo las élites políticas y empresariales, la incapacidad de renovación de los partidos políticos, las demandas populares por una relación directa con sus liderazgos, la frustración derivada de crisis políticas y la carencia de servicios públicos básicos han provocado numerosas movilizaciones y protestas en diferentes países como Chile, Perú, México, Brasil, Colombia, entre otros. Los enfoques metodológicos que buscan medir la calidad de las democracias carecen de criterios que tengan en cuenta la militarización, la securitización y el militarismo.  Investigar la calidad de la democracia en América Latina exige la comprensión de las formas de violencia que se manifiesta a través del militarismo y proceso securitización y militarización, que se reflejan, por ejemplo, en la apuesta por las Fuerzas Armadas como una fuerza salvadora o guardia pretoriana de autócratas elegidos.
