Mature Enough to Measure? Practitioners’ Accounts of Organizational Maturity and Impact Measurement for Sustainability in Project Management

Organizations increasingly measure and report sustainability, yet the impacts they report are produced in projects. This paper proposes a relational reconceptualization of sustainability maturity in project management, as the coupling of measurement means to the project decisions...

Selective Lithium Recovery from Spent Lithium Iron Phosphate Batteries Used in Solar Energy Storage

The growing adoption of lithium iron phosphate (LiFePO4, LFP) batteries in renewable energy storage systems is expected to generate substantial volumes of end-of-life batteries, presenting both waste-management challenges and opportunities for critical-mineral recovery. Although...

Prenatal kolanut exposure suppresses hippocampal dentate gyrus neurogenesis in adolescent and young adult rats

Abstract Kolanut, a social delicacy for men and women, including pregnant women, in West African countries, and in sub-Saharan African continent contains caffeine, theobromide and tannins. This study investigated the possible adverse effects of kolanut following prenatal exposure...

Indoor Air Quality (IAQ) analysis and 16S rRNA gene sequencing of indoor air pollutants in a 3000-capacity religious auditorium

A thorough molecular and environmental evaluation of microbial isolates and indoor air quality (IAQ) at a place of worship is presented in this work. The study used a dual-methodological approach, including systematic environmental monitoring to assess occupant health concerns an...

Care for Young Migrants in Gauteng: Challenging Normative Assumptions of Family and Institutional Care

South Africa is host to a significant number of young migrants who are in institutional care. This study aimed to understand how migrant youth access care, who provides it and their views about the quality of care they receive, given the precarity of urban life in South African c...

Tight (Double) Exponential Bounds for Identification Problems: Locating-Dominating Set and Test Cover

Abstract. We investigate fine-grained algorithmic aspects for classical identification problems in graphs, namely, Locating-Dominating Set, and in set systems, namely, Test Cover. In the first problem, an input is a graph [Formula: see text] on [Formula: see text] vertices and an...

Appraising the role of students' industrial work experience scheme (SIWES) in developing employable skills: Nigerian higher education institutions' stakeholders' perspective

Purpose Despite several policies, studies have revealed that the unemployment rate among Nigerian Higher Education Institution (HEI) graduates is the highest on the continent. Evidence shows that a comprehensive, practice-based Students' Industrial Work Experience Scheme (SIWES)...

A Robust and Fair Multimodal Recommender System Under Structured Modality Missingness: The Trust-Based Evaluation Framework

The growing complexity of digital real estate platforms demands intelligent recommendation systems (RS) capable of operating in data-sparse and heterogeneous environments. While transfer learning (TL) has proven effective in general RS, its application to real estate (RE) remains...

Advances in Bio-enzyme Soil Stabilization and Road Performance: A Systematic Review

Abstract Driven by the demand for sustainable construction, bio-enzyme treatments for soil stabilization, especially in road engineering, are attracting interest. This study uses a bibliometric and systematic review to analyse global research trends, key contributions, and gaps i...

Advanced intrusion detection in IoT-enabled SDWSNs using artificial intelligence and feature optimization techniques

Abstract The widespread deployment of the Internet of Things (IoT) and software-defined wireless sensor networks (SDWSNs) gave rise to new opportunities for smart environments but has also made these systems highly vulnerable to diverse cyberattacks. Conventional intrusion detect...

Constitutive Metabolomic Profiles Linked to Seasonal Climate Niche Adaptation and Resilience to Black Rot in Cabbage

Plants are dynamic chemical factories that produce diverse specialised metabolites essential for growth, defence, and environmental adaptation. Metabolomes, shaped by genetic architecture, enable plants to respond to abiotic and biotic pressures, including temperature fluctuation...

Background: Illicit drug use among older adults (aged 45+ years) is increasing globally. Despite the growing impact on older adults, studies examining illicit drug use in this population remain limited. Method: Data were drawn from Wave 21 (2021) of the Household, Income and Labo...

Can Rising Incomes Support Sustainable Well-Being? No Evidence for a “Double Dividend” in the United Kingdom

The double dividend hypothesis suggests that acting in more pro-environmental ways will not only benefit the environment but also carries a subjective well-being premium for those who do so, hence paying off doubly. We test the well-being payoff part of this hypothesis using a tw...

Refining the average µ182W and µ142Nd compositions of the Archean to Proterozoic upper crust
