Impact of Compulsory Land Acquisition for Public Infrastructure on Project Communities’ Livelihoods and Environment in Delta State, Nigeria
Authors: S. E. Irori, , V. A. Akujuru,
Published: September 2024

Land acquisition for the construction of road infrastructure in Delta State always faces resistance from the affected communities, especially related to the results of the assessment of compensation. This protest from project communities is an indication of a gap on the impact on the quality of life of the affected claimants. This paper examines the impact of land acquisition on the livelihood and environment of people whose lands were acquired as a consequence of accelerating road infrastructural development policy in Delta. The study uses data collected from secondary sources and questionnaires administered on 180 affected claimants in Delta State selected from nine (9) communities across the state using a multistage sampling procedure. The study found that acquisition has a negative effect on affected people’s livelihood such as landlessness, joblessness, homelessness, marginalization, increased morbidity, food insecurity, loss of access to common property, and social disarticulation. The study recommended that the government should ensure that some of these vexed issues on compulsory land acquisition related to landlessness, joblessness, homelessness, marginalization, increased morbidity, food insecurity, etc. are addressed.

Authors: Cannavô Vinícius Barbosa , Habowski Adilson Cristiano , Galiza Edmar
Published: September 2024

O artigo analisa o rap como uma ferramenta de resistência e crítica social no Brasil, focando nas músicas do rapper Djonga. O objetivo consiste em analisar como as composições de Djonga refletem e amplificam as questões de desigualdade social e racismo estrutural. Consideramos o rap brasileiro como um meio de expressão cultural que desafia o status quo, que visa provocar mudanças sociais através da arte. O estudo se baseia nas teorias dos Estudos Culturais, destacando o conceito de pedagogia cultural. Este conceito aborda como representações culturais contribuem para a formação de identidades e visões de mundo, operando além dos limites da educação formal. Defendemos que a cultura, vista através da perspectiva dos Estudos Culturais, não é apenas um produto de alta ou baixa cultura, mas uma forma dinâmica de expressão social e resistência. A pesquisa examina a forma como Djonga utiliza sua arte para promover uma forma de pedagogia que encoraja a insurgência e a transformação social. A partir das análises, são identificados dois direcionamentos argumentativos: (a) crítica radical das contradições de uma estrutura social e (b) destruição do sistema vigente e das verdades estabelecidas. A análise das músicas de Djonga revelam que suas letras, que abordam temas como etnia, desigualdade e outras questões sociais, utilizam uma crítica radical para desafiar as estruturas vigentes e as verdades estabelecidas. A conclusão sugere que a música de Djonga não apenas reflete a realidade das comunidades marginalizadas, mas também desempenha um papel ativo na formação de subjetividades e na promoção de mudanças sociais.

Authors: Sagarika Dash
Published: September 2024

In this paper fractional variational inequality problems (FVIP) and dual fractional variational inequality problems (DFVIP), Fractional minimization problems are defined with the help of fractional Caputo differential operator and Reimann-Liouville differential operator. The equivalence theorem of Caputo FVIP and fractional minimization problem is established. The equivalence between FVIP and DFVIP is studied with the help of fractional Bregman divergence to establish the fractional Minty’s lemma.
Introduction: The theory of variational inequality problems is one of the best tool to solve the equilibrium and non-equilibrium problems arises in the branches of Applied Mathematics, Applied Physics, Engineering, Medical, Financial and many more. On the other hand, fractional calculus manages to study various types of dynamic problems arises in real and complex analysis
It is certain for the development of fractional calculus because the fractional derivative  has global correlation, which can reflect the historical process of the systematic function.With regard to the definition of fractional derivatives, many mathematicians studied fractional derivatives from different aspects and advanced different definitions for them, for example  Riemann-Liouville (RL) derivative, Caputo derivative and other derivatives.
Conclusions: The concept of -fractionally differential inequality problem is defined and studied its existence theorem with the help of -fractionally convex function. The concept of -fractionally Bregman divergence is developed and using it the existence of -fractionally minimization problem and -fractionally differential inequality problem are studied. Equivalence theorem in between -fractionally differential inequality problem and -fractionally dual differential inequality problem is studied to establish the Minty’s lemma in fractional calculus.

Assignment of natural numbers as labels for the edges and vertices of a graph. It is based on modular arithmetic property known as congruence graph labelling of a graph.For congruence graph labeling it entails the assignment of odd integers to vertices and even integers to edges with property of congruence graph labeling. Results: This labeling method has been identified on friendship graph, shell graph, generalized butterfly graph, fan graph, P_2+mK_1 graph
Numerical Study of the 3D MHD Radiative Flow of Williamson Nanofluid with Variable Characteristics Over a Double Stretching Sheet
Authors: Boreddy Mahendar Reddy
Published: September 2024

The current study investigates the influence of variable thermal conductivity and mass conductivity on 3D MHD. The significance of this study lies in mass diffusion on a three-dimensional Williamson nanofluid fluid flow over a double stretched sheet. When thermal radiation and Hall current is present, the heat transfer process is explored to see how chemical reactions affect heat and mass transmission. Additional phenomena, such as momentum slip and convective boundary conditions, contribute to the model's uniqueness. The problem formulation becomes ordinary differential equations with application of the Von Karman similarity variable. Use of the bvp4c function in yields a numerical solution for the system of differential equations. Using MATLAB’s bvp4c function, a numerical solution to the differential equation system is obtained. A graphic is used to discuss the overall result of several metrics compared to the involved profiles. It is believed that as temperature-dependent thermal conductivity and viscosity increase, so does the temperature field. When the Williamson fluid and magnetic parameters rise, the velocity field decays in the x- and y-axis directions. To support the identified issue, a comparison between the current inquiry and a previously published work is also included.

Published: September 2024

In this work, we performed a preliminary investigation on the redox behaviour of Sr2FeMo0.6Ni0.4O6-δ (SFMN) double perovskite in H2-H2O and CH4-H2O redox cycles in order to explore the potential use of this oxide as an Oxygen Carrier (OC) in fuel-assisted Chemical Looping Water Splitting (CLWS) processes driven by concentrated solar energy. The results were compared with our previous findings on the Reverse Water Gas Shift Chemical Looping (RWGS-CL) reaction. The improvement in performance due to the bimetallic exsolution on the OC surface is observed. This OC exhibits interesting activity and stability over CH4-assisted CLWS cycling. Future investigations are planned to examine the structural transformations that might impact the redox behaviour of this material in water splitting processes.

Authors: Barea Jose Maria , Barragan Jose , Azab Khaled , Vorbrugg Oliver , Altmann Thomas
Published: September 2024

CWA Power develops, owns, and operates several CSP projects, including the largest one in the world. One of the primary objectives for companies in the Concentrated Solar Power (CSP) sector is to lower the electricity costs associated with CSP plants. This goal extends not only to existing operational plants but also to future projects. Enhancing plant performance is a key pathway to achieving this cost reduction. CSP performance models play a pivotal role in this journey by allowing us to analyse different configurations, changes, or modifications without the necessity of their physical implementation. In 2015, ACWA Power made a strategic decision to develop its own CSP performance models. This move aimed to enhance ACWA Power’s competitiveness for upcoming projects while also supporting operational plants by identifying avenues for performance improvement. The decision was made to create models for the two prevailing CSP technologies: Parabolic Trough with thermal oil as the heat transfer fluid (HTF) and molten salt storage system, as well as solar tower with molten salts.

Published: September 2024

台灣近年來，因晚婚、晚孕等因素，致使高危險妊娠案例增加；加之以醫療技術進步，原本難以懷孕的超高齡女性、患有嚴重子宮肌腺症而必須切除病灶者、因免疫或血栓問題而重複流產者，皆在獲得治療後成功懷孕，卻也使得高危險妊娠現象頻發，母嬰傷亡事故居高不下。為此，國家擬定孕產兒安全相關政策，茲就相對重要者略為概述，以幫助快速瞭解政策之規劃。

 

In recent years, factors such as delayed marriage and late pregnancies have increased the incidence of high-risk pregnancies in Taiwan. Following advancements in medical technology, women who were originally unlikely to conceive—such as those of advanced maternal age, those requiring lesion removal due to severe adenomyosis, and those experiencing recurrent miscarriages due to immune or thrombotic disorders—have successfully achieved pregnancy following treatment. However, such treatment has also led to a higher frequency of high-risk pregnancies, with maternal and neonatal mortality and morbidity rates elevated. In response to this problem, the Taiwanese government has formulated policies related to maternal and neonatal safety. A brief overview of the more critical policies is provided herein to facilitate a fast understanding of relevant national strategies.

Individuals with disabilities often face complex gender-related problems because of their special needs. In particular, women with disabilities often face many challenges pertaining to reproductive health, gender-based violence, and chronic disease management. In addition, transportation difficulties and financial constraints further hinder their access to continuous chronic disease care and management. Compared with women, men with disabilities have higher needs for mental health and accident prevention; however, social expectations and gender role pressure often deter such men from seeking psychological support. Transgender individuals with disabilities have complex requirements related to gender-affirming treatment and often face discrimination and misunderstanding in medical settings. To solve this problem, medical institutions should enhance gender awareness among their medical personnel to promote inclusivity and improve service quality. Therefore, it is necessary to strengthen the focus on the specific gender health needs of individuals with disabilities from various aspects. This includes providing gender-sensitive training courses, and establishing effective support mechanisms, such as measures to prevent gender-based violence prevention and offering psychological support services. These efforts are essential to ensure that individuals with disabilities receive equal rights and safety in addressing their unique gender issues.

Published: September 2024

Background:  Pain catastrophizing can be defined as a series of negative thoughts about an actual or potential painful experience. Temporomandibular dysfunction (TMD) is a collective term for a painful musculoskeletal syndrome, temporomandibular joint and the associated structures. Aim: Evaluate the level of pain catastrophizing in individuals with TMD. Methods: a total of 40 participants were evaluated and divided into two groups: a control group with 20 individuals without TMD and an experimental group with 20 individuals with TMD. Participants with TMD were evaluated through medical history and clinical examination considering their chief complaint and followed the Research Diagnostic Criteria for Temporomandibular Disorders. The Pain Catastrophizing Scale was applied to all participants in both groups. Results: Although women represented the largest group with TMD, they did not present higher levels of pain catastrophizing compared to men. Age was not statistically relevant, which contradicts some previously published studies. The group with TMD had a higher pain catastrophizing index (p ≤ 0.001), but no TMD subtype was related to this index. Rumination, magnification, and hopelessness were relevant in this study and showed high correlation with TMD. Conclusions:  patients with TMD presented higher scores of pain catastrophizing than healthy individuals.

Objetivo: relatar o caso clínico de um paciente com perda de dimensão vertical de oclusão (DVO) associada à erosão dentária causada por refluxo gastroesofágico, discorrendo aspectos inerentes ao diagnóstico, planejamento, execução e tratamento reabilitador com restaurações indiretas cerâmicas. Descrição do caso clínico: Paciente de 37 anos queixou-se de desgaste dentário, que provocava dor e incômodo estético com o seu sorriso. O paciente relatou ser portador da doença do refluxo gastroesofágico e possuir dores de cabeça frequentes, e o exame clínico denotou perda da DVO. Após os protocolos fotográficos, molde e análise do exame radiográfico, determinou-se clinicamente o restabelecimento da DVO, sendo que por meio dos mock-ups, verificou-se a adaptação do paciente com relação a nova DVO. Preparos para facetas e tabletops foram realizados, seguidos de selamento imediato da dentina. A reabilitação foi iniciada pelo arco superior, sendo que para este arco, optou-se pelo fluxo analógico. Peças em dissilicato de lítio fresado e maquiado foram confeccionadas, e cimentadas com cimento resinoso dual. Para o arco inferior, foi utilizado o fluxo digital, e as peças foram obtidas por fresagem. Após a finalização da reabilitação, o paciente mostrou-se satisfeito com o tratamento, com melhora no aspecto estético-facial-dental, além das dores de cabeça. Considerações finais: O restabelecimento da DVO por meio de restaurações indiretas em pacientes com erosão dental é um procedimento previsível, desde que seja precedido de uma anamnese completa, diagnóstico da DVO por meio de restaurações provisórias e estratégias de adesão e cimentação adequadas.

Introdução: A Endodontia é uma especialidade odontológica que visa controlar e tratar inflamações e infecções pulpares e perirradiculares. Para tanto, técnicas de preparo químico-mecânico são empregadas, tendo como adjuvante a irrigação com substâncias químicas auxiliares, como o EDTA e o hipoclorito de sódio. No entanto, a completa limpeza dos sistemas de canais radiculares (SCR) ainda é um desafio. Diante disso, diversos sistemas para potencializar o efeito das soluções químicas têm sido empregados, como a irrigação passiva ultrassônica, o sistema Easy Clean e o Endovac. Além disso, limas de ativação de solução irrigadora, como a XP-Endo Finisher e a XP Clean, foram introduzidas para aprimorar a limpeza e desinfecção dos canais radiculares.  Objetivo: Avaliar, por meio do auxílio de um microscópio eletrônico de varredura (MEV), o formato e superfície de dois instrumentos endodônticos utilizados para limpeza de canais radiculares. Metodologia: Este estudo analisou a superfície das limas XP-Endo Finisher e a XP Clean utilizando MEV, comparando-as quanto ao formato e à composição química. Resultados: Os resultados revelaram que as limas, apesar de serem destinadas à agitação da solução irrigadora, apresentam características distintas. A XP Clean apresenta ponta ativa e a XP-Endo Finisher exibe ponta inativa com melhor polimento de superfície. Conclusão: A escolha entre esses instrumentos deve considerar, não somente o formato e o polimento de superfície, mas também o seu custo-benefício.

Authors: Civelek Pınar , Yeşil Pervin , Güzel Mesut
Published: September 2024

The aim of this study is to identify the factors that influence individuals' perception of visual quality in a coastal park. To achieve this, a visual questionnaire was conducted among students who frequently visit the park. The data collected was analysed using statistical methods. The study concluded that gender does not significantly affect visual quality perception. Additionally, there was no difference in visual quality perception between participants who live by the sea and those who do not. However, the number of years that participants have lived in the city does have a relative impact on their perception of visual quality. The study found that visual quality perception remained relatively stable for those living in the city for up to 2 years but increased for those living in the city between 2 and 3 years. However, for those living more than 3 years, the perception of visual quality then gradually decreased.

Published: September 2024

While the success of schools is often attributed to the efforts of principals, it is important to determine how schools can embrace distributed instructional leadership to enhance academic performance among learners. It is evident that instructional leadership alone is inadequate and necessitates complementation with a distributed leadership model. This study exclusively focuses on how instructional leadership aligns with distributed leadership, paying special attention to distributed instructional leadership implementation in primary schools in Zimbabwe. In this particular qualitative study, the interpretivist theory served as the guiding framework. The study involved observation and conducting interviews with school teachers and principals to gain insight into the instructional and distributive leadership activities that were taking place within their respective schools. The analysis of the data was approached through the lens of Hallinger and Murphy’s model of instructional leadership. The findings of the study highlighted the importance of active involvement from all members within a school for effective leadership. Furthermore, it was revealed that a holistic approach to school leadership styles is essential, emphasizing the interconnected nature of instructional and distributive leadership activities (distributed instructional leadership). The study ultimately determined that distributed instructional leadership is achieved through collaborative efforts in formulating school visions and embracing shared supervision practices among the members of staff. It was also identified that creating opportunities for staff development in the schools plays a pivotal role in reaching the goals of distributed instructional leadership.
IMAGINARIES OF INTERNATIONAL SOCIETY:CROSS-ROADS FROM ‘ROME’, ‘SERENDIPPO’, AND ‘YALTA’
Authors: GROVOGUI Siba N’Zatioula
Published: September 2024

To the extent that it infers ‘society’, international society is understood as the institutionalization of shared interests and norms. It arises as a result of phenomena, dynamics, and processes, across time and space. These are misunderstood partly because disciplinary science has occulted many. One of the factors leading to amnesia is the commonsense status currently held by Western canons in which the modern state and exclusive civilizational norms are identified as central identity and desire (or aspiration) of international society. This is particularly the case with the so-called English School. The problem is not merely that this school is perennially bound up in a post-imperial fantasy of inherent goodness of the West. It is also that it elides the fact that post-World War II imaginaries of power, interest, legality, legitimacy, and their terms and articulations are medieval in origin. My hunch is that even the received images of the Middle Ages are distorted in disciplinary canons. The paradox is that it would be impossible for the collective ‘us’ to properly project ourselves in the future without correcting the errors of disciplinary canons and their archives.
RESPONSIBLE AI: TRANSFORMING CLIMATE ACTION IN INTERNATIONAL RELATIONS
Authors: ŞEKER Şadi Evren , BÖREKÇİ Fatih Hüseyin
Published: September 2024

As AI technologies advance, their application in data analysis, predictive modeling, and strategic decision-making becomes increasingly integral to developing innovative solutions to combat the environmental challenges of our time. This narrative explores the pivotal role of responsible AI in the mitigation of the climate crisis, emphasizing the critical need for ethical, equitable, and effective AI implementations within the sphere of international relations. Central to this discourse is the concept of responsible AI or AI ethics, which advocates for the infusion of ethical principles and humanistic values throughout the lifecycle of AI technologies—from their inception and development to their deployment and operational use. The ethos of responsible AI is particularly salient in the context of climate change, where it underpins the operational integrity of AI applications, ensuring they are governed by ethical standards that emphasize data security, privacy, fairness, and environmental stewardship. In the realm of Ethical and Fair Decision- Responsible AI champions the principle of Inclusion of Diverse Perspectives, advocating for the active participation of varied societal segments and expert groups in the AI development process. This inclusivity enriches the decision-making landscape, engendering a more comprehensive and participatory approach to climate action. For AI to exert a substantive and positive impact on the climate crisis, it is imperative that policymakers, developers, and other stakeholders collectively embrace and actualize the principles of responsible AI. The study underscores the transformative potential of artificial intelligence (AI) in addressing the global climate crisis through a strategic examination of national legislation, international environmental treaties, and the analytical prowess of AI in processing climate data. It highlights the imperative of embedding ethical and responsible AI practices within the framework of existing and forthcoming climate-related legal instruments. This compact methodology focuses on dissecting how national laws and international agreements are increasingly integrating AI to bolster climate action, ensuring these innovations for a unified global response to the climate challenge. The ethical framework proffered by responsible AI furnishes a robust foundation for climate-related policymaking, alleviating the cognitive and ethical load on decision-makers. This framework encourages the formulation of policies that are not merely technologically innovative but also socially conscientious and ecologically responsible. In sum, the integration of AI into climate crisis resolution, guided by the principles of responsibility, ethics, and inclusivity, heralds a promising avenue for fostering global environmental sustainability and enhancing international cooperation in the face of one of the most daunting challenges of our time.
A method for reducing credit scores’ sensitivity to economic conditions
Authors: Cuevas Herminia , Palomeque Esther , Santa-Cruz Beatriz
Published: September 2024

The cyclicality of credit risk capital requirements has been a matter of concern for banking
regulators, supervisors and the industry for years. The sensitivity to economic conditions
of the probability of default (PD) grades to which credit exposures are assigned is often one of
the most relevant sources of such cyclicality. Moreover, it is often assumed that a grade
assignment method with a high differentiation capacity inherently leads to a high sensitivity to
economic conditions. In order to challenge this assumption and foster further research –but with
no intention of setting any expectation or recommendation for financial institutions –this article
explores a methodology aimed at limiting the sensitivity to economic conditions of a pre-existing
score while maintaining its differentiation ability, by adding a module to it. This module
subtracts an amount which reflects the estimated effect of economic conditions. This allows
the original and the adjusted scores to coexist and be used for different purposes. After testing
that the methodology works on a synthetic dataset, its effectiveness is confirmed on a real
dataset obtained from Banco de España internal sources. The results indicate a significant
reduction in the variability of PD and risk weights when comparing a PD calibration of the
original score with a PD calibration of the adjusted score.
Revisiting the estimation of the cost of equity of euro area banks
Authors: Fernández Lafuerza Luis , Melnychuk Mariya
Published: September 2024

The aim of this article is to estimate the cost of equity for a large sample of euro area banks.
To this end, the authors consider several estimation methodologies falling under two main
approaches: (i) multi-factor time-series models of stock market returns; and (ii) dividend
discount models. It is found that, at country level, the estimates of the various models display
a similar time variation, but differences in levels can be substantial. The relationship between
the different cost of equity estimates and bank observables is relatively weak. Estimates from
dividend discount models show a somewhat more robust relationship with bank fundamentals,
while those from factor models do so more clearly only for larger banks. A combined measure
built as a simple average across models also shows a moderate association with fundamentals.
Overall, the results highlight the uncertainties inherent in cost of equity estimation and the
importance of considering different alternative models.
