Beyond think-aloud: Toward a representational–recursive agenda for multimodal process-tracing research in learning and instruction

Background Think-aloud traditionally has been conceptualized as a means of accessing cognitive processes through verbal report. The nine studies in this special issue reveal a broader methodological transition in which verbal protocols increasingly are combined with eye tracking,...

Nigeria’s soft power and cultural diplomacy: revisiting the 1988 cultural policy

Academic scholarship on Nigeria’s soft power has increasingly examined the concept through the lens of the country’s cultural exports, philosophical ideals, foreign policy, and political values. However, there remains a notable gap in the literature regarding the role and relevan...

Towards a data-driven circular economy in Africa; life cycle inventory insights from Ghana's concrete sector

Purpose The usage of generic databases for environmental impact assessment does not respond to the uniqueness and peculiarities of certain regions. An array of reasons accounts for this including energy mix technology, manufacturing system boundaries, environmental policy framewo...

Modelling the Interdependence Nexus Among Exchange Rates, Precious Metals, and Energy Prices in Emerging Markets: A Vine Copula Approach

This study investigates the interdependence among exchange rates, equity indices, precious metals, and energy prices across emerging markets, utilising daily data from 8 August 2005 to 30 August 2025. The study utilised a Vine Copula-based ARFIMA-SGARCH model to capture nonlinear...

South Africa and Qatar in Gaza and Beyond: A New Dawn for Transformative Third-Party Intervention?

As geopolitical realignment intensifies conflict and exposes failures in Western-led intervention, space is opening for alternative actors and approaches. Gaza marks a critical juncture as non-Western third-party actors assume prominent roles, raising questions about their interv...

Grandiose and vulnerable narcissism as predictors of manipulation tactics

Narcissism is associated with the manipulation of interpersonal encounters to fulfil specific interpersonal needs. Grandiose and vulnerable narcissism are driven by different interpersonal needs, yet it is unclear whether these differences appear in their manipulation tactics. Th...

A Physics-Guided Statistical Framework for Bearing Fault Diagnosis Under Unit Variability and Rotational Speed Uncertainty

Reliable bearing fault diagnosis must differentiate between defects and normal-operation-condition variation. The predictor must remain accurate when shaft speed is uncertain. Conventional accuracy-driven models often ignore false-positive rates and fail to accurately locate faul...

Impact of acceptance and commitment therapy on work resilience among restaurant and hotel workers in tourism zones: a case of multivariate analysis

Background: Cooperative efforts and the courage to withstand difficult times among workers in an organization enhance productivity. However, some employees become discouraged by hard times and unusual tasks in the organization, which leads to low resilience among workers. Empiric...

A reflexive thematic analysis of how South African men make sense of suicidal distress and recovery

Men consistently account for the majority of suicide deaths globally, and South African men are no exception, however the cultural and personal meanings these men attach to their own suicidal experiences remain underexplored. This qualitative study, informed by phenomenological s...

Data-driven modeling of Galactic diffuse emission with multi-wavelength observations

Abstract We present a data-driven investigation of Galactic diffuse emission. Using multi-frequency Planck maps (30–857 GHz), we construct a non-linear mapping between microwave-to-far-infrared and gamma-ray intensity through supervised machine learning. Our models achieve high p...

The correlations of the urban environment with walking and cycling in Sub-Saharan Africa: Systematic review

Walking and cycling are crucial for promoting sustainable urban mobility, public well-being, and environmental benefits. However, in Sub-Saharan Africa (SSA), the uptake of these active transportation modes remains influenced by a range of built environment and socio-economic fac...

Negotiating AI integration in higher education curricula: Coping behaviour or career opportunity?

This study examines how higher education educators perceive artificial intelligence (AI) as both a coping resource and a catalyst for career development. Grounded in the Stimulus-Organism-Response (S-O-R) framework and integrating Social Cognitive Career Theory (SCCT) with Lazaru...

From Cognitive Substitution to Cognitive Amplification: Artificial Intelligence, Higher-Order Learning and Real-World Readiness in Online Postgraduate Public Health Education—A Scoping Review

Background: Online postgraduate (PG) public health education must develop higher-order competence and readiness for practice. Generative artificial intelligence (genAI) may enhance feedback, simulation and scaffolding, but may also substitute for learner reasoning. This review ex...

Determining Susceptibility to Sinkholes Due To Climatic Factors in Ekurhuleni: A Multi-Criteria Decision-Making Approach

The occurrence frequency and intensity of many geoenvironmental hazards such as landslides and sinkholes have increased over the years, partly due to climate change. However, the effects of such occurrences and the spread of sinkholes have not been thoroughly explored by research...

An Optimization-Based Truthfulness Framework with an Inertial Influence Algorithm for Consensus Decision-Making in Smart Grid Planning

Group decision-making is important in many real-world applications, particularly in smart grid planning, where different stakeholders need to work together to identify appropriate strategies for energy infrastructure deployment. In this study, we develop an optimization-based tru...

Nature-based solutions in built environment education for developing sustainability competencies through bibliometric and systematic analysis

Abstract Nature-based Solutions (NbS) are increasingly recognized for their potential to address complex urban sustainability challenges; however, their integration into higher education curricula within built environment disciplines remains fragmented. This study examines how Nb...

An experimental study on the performance of Resin-grouted bolts under pull-out tests in laboratory and in-situ environments

Abstract Adhesive anchors are widely used in geotechnical engineering, yet few studies compare resin systems under matched conditions in both laboratory and field settings. This study evaluates the tensile capacity, governing failure mode and failure mechanisms of epoxy and vinyl...

Generative AI vs. future competencies of Nigerian public university students

The rapid diffusion of Generative Artificial Intelligence (GenAI) in higher education is reshaping the development of key competencies such as critical thinking, creativity, and collaboration, while simultaneously raising concerns about learner autonomy, originality, and deep cog...

How Structural Segmentation Shapes Petroleum‐System Efficiency in a Transform‐Modified Rift: Insights From the Saltpond Basin (Offshore Ghana), Equatorial Atlantic Margin

ABSTRACT Rifts host a substantial proportion of the world's hydrocarbon resources because lithospheric extension commonly generates sustained subsidence, thick sedimentary fills and laterally connected migration systems that enhance petroleum‐system efficiency. In transform‐modif...
