Introduction: Acute respiratory infections (ARIs) remain a major cause of morbidity in children, particularly in disadvantaged communities where living conditions and access to healthcare are precarious. In the Kamina Health Zone, the factors associated with these infections remain poorly documented. This study aimed to identify the determinants of ARIs in children aged 0 to 14 years. Methods: A community-based cross-sectional analytical study was conducted with 384 children aged 0...

Industrial dumpsites can impose complex pressure on nearby water sources through dissolved ions, oxygen demanding substances, microbial inputs and toxic metals. This study assessed the physicochemical quality, Water Quality Index, toxic metal burden and human health risk of water sources around fertilizer, dye, battery and paint dumpsite vicinities in Makurdi, Nigeria. Water categories comprised fertilizer dumpsite water sample (FDWS), dye dumpsite water sample (DDWS), battery dumpsite water sam...

Against the backdrop of comprehensively advancing the digital transformation of education and implementing the fundamental task of fostering virtue through education, the deep integration of artificial intelligence (AI) technology with primary mathematics teaching offers new possibilities for addressing practical dilemmas such as the absence of emotional education and the singularity of teaching strategies in traditional classrooms. This paper presents a conceptual framework rather than an empir...

Against the dual policy backdrop of the state’s drive to enhance the quality of international Chinese language education and promote the dissemination of Chinese intangible cultural heritage abroad, Chinese language teaching in overseas primary schools is generally plagued by practical issues such as the inadequate suitability of teaching resources for intangible cultural heritage, monotonous teaching methods, a lack of cultural literacy among teachers, and high barriers to the implementat...

This article examines how Jenni Fagan’s The Panopticon portrays the traumatic experiences of marginalized youth subjected to institutional surveillance and social exclusion. Drawing on trauma theory, Foucauldian panopticism, and resilience studies, it analyzes the ways trauma fragments identity while institutional labeling reinforces marginalization and stigma. Through the character of Anais Hendricks, the study highlights the psychological effects of abuse, abandonment, and discipl...

The gastronomy sector is continuously evolving in response to changes in both supply and demand. Gastronomic establishments strive to adapt their services to the needs of individuals, families, business professionals and tourists. Their success largely depends on effective human resource management, making leadership an important factor in organizational performance. Contemporary leadership approaches emphasize employee motivation, collaboration, flexibility and ethical behavior, which contribut...

This study investigates the application of Artificial Neural Networks (ANN) for predicting welding-induced transverse distortion in Tungsten Inert Gas (TIG) welding of 10 mm thick ASTM A36 mild steel plates. Experimental data from a Face-Centered Central Composite Design (FCCD) were used to train, validate, and test a feedforward ANN model with four input parameters (current, voltage, gas flow rate, and welding speed) to produce a single response output of transverse distortion. The ANN model de...

Artificial intelligence (AI) is one of the most disruptive technologies that have been impacting e-commerce. This review paper will consider AI applications in e-commerce, as well as its challenges and future developments. First of all, this paper will focus on the use of AI in the form of personal recommendations, chatbots, and virtual assistants and sentiment analysis for managing customers’ feedback. In addition, the paper will provide an overview of the use of AI for supply chain and l...

Methodology: In this paper, we aim to investigate endemic and epidemic transitions in the SEIQRV model using catastrophe theory. By incorporating nonlinear interactions among susceptible, exposed, infected, quarantined, recovered, and vaccinated populations, the model reveals that disease dynamics may undergo abrupt qualitative changes under small variations in epidemiological or control parameters. Using catastrophe-theoretic analysis, we show that epidemic onset, persistence, and elimin...

Methodology: This study formulates a 5 × 5 SEIRV (Susceptible-Exposed-Infected-Recovered-Vaccinated) nonlinear epidemic matrix model to investigate epidemic dynamics through catastrophe theory. The nonlinear system is reduced near equilibrium points, and the infected population dynamics are transformed into a cubic structure equivalent to the cusp catastrophe model. Analytical methods are employed to derive conditions for multiple equilibria, bifurcation, and sudden epidemic transiti...
