Navigating the Unknown: The Sociocultural and Metacognitive Architecture of Wisdom

Psychological wisdom research has shifted from characterizing rare exemplars and desired outcomes to specifying processes that support sound judgment under uncertainty. Yet it has advanced along two siloed research tracks: one on folk theories-cultural tools such as exemplars, na...

What makes an effective ideator? The distinct roles of cognition, personality, and experience in early-stage venture ideation

A microfoundational account of organizational innovation capability should explain which individual-level attributes distinguish ideators who are better able to generate, select, and elaborate ideas into investment-worthy business concepts. Yet research remains fragmented because...

Unified multi-task YOLO-Lite framework for road defect detection and image-level classification with edge-optimized quantization and explainable visual inference

Automated road defect assessment requires models that can accurately localize pavement damage, identify the overall defect category, and operate with limited computational resources. However, most existing approaches address object-level detection and image-level classification u...

Preserving Sacred Forests and Rivers in Abanyom, Cross River State, Nigeria: Is the Environmental Worldview Eco-Centric, Anthropocentric or Relational?

Abstract The debate surrounding the ethical nature of the African environmental worldview remains inconclusive, with some scholars arguing that it is primarily eco-centric, while others claim that it is largely anthropocentric. Using the case study of Abanyom’s preservation of sa...

Gravimetric, culture-based and public transcriptomic perspectives on low-density polyethylene feeding in Galleria mellonella

Abstract Galleria mellonella can remove substantial amounts of low-density polyethylene (LDPE), but host and microbial contributions remain unresolved. We examined whether antimicrobial exposure altered time-dependent LDPE mass disappearance and integrated gravimetric, culture-ba...

Seeing Inequalities: Self-Reported Visual Difficulty and Eye Care Utilization Among Women in Malawi, a Secondary Analysis of the 2024 Demographic and Health Survey Data

Background: This study aimed to identify the factors associated with self-reported visual difficulty and uptake of spectacle/contact lens correction among women of reproductive age in Malawi. Methods: We conducted a cross-sectional secondary analysis of the 2024 Malawi Demographi...

Climate stress, migration, and emotional dimensions of malaria vulnerability: a mixed-methods study in an urban informal settlement, South Africa

Vulnerability to malaria in Thembelihle arises in a context of climatic instability, environmental degradation, and high mobility, which shape how residents interpret health risks. Erratic rainfall, flooding, and heat stress interact with inadequate drainage, stagnant water, and...

Chemical Forensics in Death Investigations: A Comprehensive Review of Stable Isotopes as Postmortem Biomarkers for Food Contamination Tracking

Lethal foodborne illness outbreaks represent a critical intersection of public health surveillance, environmental health, and forensic toxicology. When acute gastrointestinal syndromes lead to sudden death, traditional postmortem investigation techniques are often hindered by tis...

A Cross-Sectional Study to Understand COVID-19 Vaccine Hesitancy Among Nursing Students and Health Workers: Implications for Future Outbreak Preparedness in South Africa

Background: Vaccine hesitancy is a global challenge affecting workplaces and academic institutions. Despite efforts, low vaccination rates persist in South Africa, increasing the risks associated with pathogen exposure. This study assessed the knowledge, attitudes, and perception...

Competing geochemical drivers and probabilistic health risk assessment of groundwater in the semi‑arid Voltaian sedimentary basin, Ghana

Groundwater in semi-arid sedimentary basins is a critical rural resource, but quality assessment is often weakened by geochemical complexity, compositional closure, class-boundary uncertainty and incomplete exposure information. In the Voltaian sedimentary basin of Ghana, previou...

Health effects associated with emissions from household generators used for backup power in Africa: a scoping review

In many low- and middle-income countries, unreliable electricity supply has led to widespread reliance on petrol (gasoline) and diesel generators. The type of fuel influences both the quantity and composition of emissions, which contribute substantially to air pollution and pose...

Inception Display Calculi

Abstract Display calculi were introduced by Nuel Belnap in [3] as a natural extension of Gentzen’s sequent calculi, as a uniform and modular framework capable of encompassing broad classes of logics. In [28], the properly displayable (D)LE-logics are syntactically characterized a...

Cybersecurity Strategies in European SMEs: Navigating Digital Risks and Enhancing Cyber Resilience

Abstract Cybercrime rates have increased rapidly during the last decades, resulting in cybercrimes becoming common crimes and leading to the importance of companies’ attention to cybercrime experience. Therefore, this study examines cybercrime experience and provides insights int...

Multilevel bivariate analysis of childhood anemia and anthropometric failure among under-five children in sub-Saharan Africa

Abstract Childhood anemia and malnutrition remain critical public health challenges in Sub-Saharan Africa (SSA), with anemia affecting approximately 47.4% of preschool children globally. A cross sectional secondary data analysis from recent Demographic and Health Survey data was...
