Internalizing corporate social responsibility (CSR) in ASM: The making of small-scale miners as environmental and work safety “‘champions’” See

Purpose: While the practice of corporate social responsibility (CSR) in the mining sector is far from a new occurrence, far less common is an examination of the CSR-related activities of artisanal and small-scale mining (ASM) firms. Drawing on Carroll (1991) four-part model ...

Transforming Ghana's ASM industry: The intersection of ‘mining schemes’ and stakeholder collaboration See

Weak institutional frameworks related to artisanal and small-scale mining (ASM) operations have exposed many mineral-rich countries to negative environmental consequences. In Ghana, for example, mining-related environmental challenges led to a total ban on ASM activities in 2017. In light of this...

Friends or foes: Can large-scale mining companies partner with small-scale miners? Yes, they can? See

This paper (re)examines the nexus between large-scale mining (LSM) activities and artisanal and small-scale mining (ASM) operations. Broadly speaking, the existing combative resource politics between the two mining entities has created room for the emergence of divergent opinions on sustainable s...

The role of solute clusters in the nucleation of precipitates in Al–Mg–Si–Cu alloys See

In this work the precipitation behaviour of both high and low Cu variants of a Al-6xxx alloy were investigated with and without natural ageing. The material yield strength was greater in the high Cu alloy and without natural ageing. The strength was seen to correspond to&...

Turning to Religion: NGO Accountability in a faith-based development organisation See

The purpose of this paper is to investigate whether NGO accountability processes are influenced by religion. To achieve its aim, the paper draws on interview data from officers working in a faith-based NGO in Ghana. The officers describe their work as a commission to God ...

Integrating machine learning with a positioning mechanism for managing interference and power consumption in a multilayer fleet of unmanned aerial platforms See

The soaring global demand for ubiquitous wireless connectivity, which epitomizes the digital era, can only be fulfilled with heterogenous networks that, increasingly, need to include aerial platform fleets for a more holistic approach. However, deploying aerial platforms to serve as a fleet&...

Role of shock waves in materials processing: Fundamentals and applications See

In recent years, ultrasonic processing (USP) technology has led to some of the most promising scientific breakthroughs in the field of pharmaceutical, food, environmental and material sciences leading to advancements in manufacturing, process efficiency, and material performance. However, the industri...

Satellite imagery pre-processing and feature extraction for the mapping of coastal ecosystems using Google Earth Engine See

The use of Google Earth Engine (GEE) is increasingly common in geospatial analysis of satellite images for various environmental management purposes due to its easy accessibility and capabilities to support complex pre-processing and mining of geographic data. In the context of coastal ...

Characterization of Cu-Nb-Cu heterostructure fabricated by high-pressure torsion See

High-pressure torsion (HPT) processing disrupts the thermodynamic equilibrium in immiscible systems and often produces nonequilibrium microstructures with unique properties. This study investigates the microstructural evolution and mechanical behaviour of a Cu-Nb immiscible alloy subjected to HPT under 6 GPa&#x...
