Well-being in digital-free tourism: A mixed-methods rhythmanalysis

Tourism research has largely treated well-being as a motivation or outcome, neglecting how it unfolds in-situ and relying on self-report data. Through a mixed-methods rhythmanalysis, this study examines how well-being emerges and evolves in digital-free tourism. Following 23 part...

Phenotypic, bioactive and metabolomic diversity among indigenous Southern African underutilised monkey orange (Strychnos spinosa Lam.) fruit accessions

Strychnos spinosa Lam. is an indigenous African fruit tree with considerable phenotypic diversity, yet the extent to which visible fruit morphotypes correspond to biochemical and metabolic variation remains poorly resolved. This study integrated fruit morphology, physicochemical...

Enhancing copper and cobalt hydrometallurgical leaching through deep learning-based process optimisation

This study presents a comprehensive machine learning framework for the optimisation of metallurgical parameters for the grinding, leaching and solid/liquid separation in a Congolese Copperbelt hydrometallurgical plant. Three deep learning architectures namely Deep Neural Network...

Heat treatment technique and fuelwood density shape silcrete flake-edge geometry

Silcrete heat treatment was a transformative technological innovation in the Middle Stone Age, enabling toolmakers to improve the flaking properties of this raw material. Recent research has highlighted that silcrete heat treatment is not a uniform process, different silcrete sou...

A Novel Modified Total Generalized Variation Technique for Image Denoising

The process of image denoising is very crucial in the field of image processing, since noise tends to adversely affect both the appearance and structure of images that are applied in different fields of study such as science and engineering. In this research paper, we present a n...

Effect of Cognitive Behavioural Intervention on Stress and Resilience among Agricultural Students Engaged in Okro and Pepper Production Practicals

In the Nigerian university environment, students face various stressors that can hinder their academic performance. Despite their dedication to achieving academic success, the challenging environment can be a barrier. While there is existing research on stress, none has focused s...

Beyond ‘diversity of values’: power, pluralism and transformative change in biodiversity conservation

The concept of value has, again, become a major bone of contention in biodiversity conservation. Responding to natural capital approaches that aimed to illuminate natures economic value, critics argued that this economic emphasis not only ignores but strengthens the root causes o...

Supply chain antifragility capabilities: a systematic literature network analysis and conceptual framework

Purpose Supply chains are essential to economic growth in many industries. However, their complexity and slow response to market changes leave them vulnerable to environmental disruptions. The concept of antifragility explains how organizations can withstand and even thrive durin...

Legal Fragmentation and Teacher Protection in South African Inclusive Education Classrooms: A Critical Document Analysis

Inclusive education in South Africa is based on constitutional rights to equality, dignity, and basic education, with teachers as key implementers. However, teacher responsibilities are clearly defined, but the legal protections supporting these duties are fragmented across vario...

Phenotypic misidentification of Staphylococcus aureus clinical isolates and the absence of routine MRSA screening in selected health facilities in the South West and Littoral Regions of Cameroon

Staphylococcus aureus , particularly methicillin-resistant S. aureus (MRSA), is a major cause of infection and antimicrobial resistance in resource-limited settings, and accurate detection depends on reliable species identification and methicillin-resistance screening. In many su...

Socio-Demographic and Environmental Factors as Predictors of Pro-Environmental Behaviour Among South Africans

This study examined the predictors of pro-environmental behaviour (PEB)among South Africans, with the aim of understanding how socio-demographic and environmental variables influence individuals’ engagement in environmentally responsible actions. The research sought to determine...

Efficacy of knowledge management processes among information professionals for organisational productivity in academic libraries

Purpose This paper aims to explain how knowledge management processes (KMP), which encompass the identification, organisation, creation, sharing and utilisation of knowledge, contribute to increased organisational productivity among information professionals in academic libraries...

“Jock and the Great Outdoors”: White American Masculinities, Gay Reader-Tourists, and Fantasies of Africa in Postwar Physique Magazines

This article draws from critical discourse analysis to explore motifs in editorial information produced on images by the South African photographer Jock in postwar physique magazines aimed at (mostly white) gay readerships. The research shows that these recurrent narratives turne...

Sampling-Frequency-Aware Wavelet-Statistical Features for Fault Diagnostics in Inverter-Integrated Medium-Voltage Networks

Inverter-based resources (IBRs) alter fault behaviour in medium-voltage (MV) networks, while heterogeneous monitoring devices operating at different sampling rates provide different bandwidths and representations of fault transients, complicating consistent feature formulation fo...

Role of Resonances in Total, Coulomb, and Nuclear Breakup Cross Sections for Light and Heavy Targets

Abstract The influence of resonances on the breakup dynamics of the $${^6}$$ Li+ $$^{58}$$ Ni and $${^6}$$ Li+ $$^{208}$$ Pb systems is investigated using the continuum discretized coupled-channels (CDCC) method at incident energies above the Coulomb barrier. The calculated elast...

The Role of Technology and Innovation Management in Enhancing Productivity Management Within Small and Medium-Sized Manufacturing Enterprises (SMEs) in South Africa

This study investigates the role of technology and innovation management (TIM) in enhancing productivity management within small and medium-sized enterprises (SMEs) in South Africa. Using Jenga’s Theory of Creativity, Systems Theory, and Schumpeter’s Theory, the research seeks to...

A Fuzzy Multi-Criteria Decision-Making Framework for Optimal Mining Method Selection in Complex Geological Conditions

Mining Method Selection (MMS) is a complex, multi-criteria decision-making problem influenced by geological, technical, economic, environmental, and safety factors. Traditional methods, such as Nicholas, University of British Columbia (UBC), and reformed UBC approaches, rely on e...

Constructing and negotiating boundaries between product management and project management in digital product environments

Purpose This paper examines how practitioners make sense of and negotiate boundaries between product management and project management in digital product environments, with particular attention to temporal orientations, governance interfaces, role accountabilities and decision ri...

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...

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,...
