The purpose of this paper is to investigate the trend of transatlantic strategic convergence and policy coordination in response to Chinese trade practices and technological competition, specifically in the critical minerals sector.

The research draws on primary and secondary source material to identify evidence of and examine the drivers, manifestations and prospects for effective US-European efforts to advance the shared aim of reducing vulnerabilities in critical minerals supply chains.

The interests of the USA and Europe would be best served by prioritizing their own security, diversification and resilience strategies while seeking areas of common ground and constructive engagement with China.

The research offers a fresh perspective on the growing alignment and persistent gaps in US and European perspectives on China’s rising influence and assertive behavior.

The research highlights the vital role of critical minerals in national security, economic competitiveness, technological advancement and sustainable resource management. It underscores the shared recognition on both sides of the Atlantic that securing a stable supply of critical minerals – essential for maintaining strategic capabilities, driving innovation and ensuring long-term economic prosperity – necessitates tighter transatlantic coordination as well as constructive engagement with China.

The Minerals and Petroleum Resources Royalty Act (MPRRA) became effective on 1 March 2010. This legislation may have a significant impact on employment, foreign investment and future exploration in the South African mining industry. This article reports on a critical analysis of the MPRRA prior to its implementation in order to identify aspects that may impact adversely on the South African mining industry and would require further research after the implementation of the MPRRA. Based on the findings, the authors recommend that the impact of the level of royalties levied as well as the mechanism to promote downstream beneficiation be researched to establish whether the legislators ought to reconsider these provisions in the light of their impact on the mining industry.

Important differentiating attributes in the procedures used, the characteristic mineral composition of the binders, and the implications these have on the final long term stability and physico-mechanical performance of the concretes produced are identified and discussed, with the intent to improve transparency and clarity in the field of geopolymer concrete technologies.

This state-of-the-art review covers the area of geopolymer concrete, a class of sustainable construction materials that use a variety of alternative powders in lieu of cement for composing concrete, most being a combination of industrial by-products and natural resources rich in specific required minerals. It explores extensively the available essential materials for geopolymer concrete and provides a deeper understanding of its underlying chemical mechanisms.

This is a state-of-the-art review introducing the essential characteristics of alternative powders used in geopolymer binders and the effectiveness these have on material performance.

With the increase of need for alternative cementitious materials, identifying and understanding the critical material components and the effect they may have on the performance of the resulting mixes in fresh as well as hardened state become a critical requirement to for short- and long-term quality control (e.g. flash setting, efflorescence, etc.).

The topic explored is significant in the field of sustainable concrete technologies where there are several parallel but distinct material technologies being developed, such as geopolymer concrete and alkali-activated concrete. Behavioral aspects and results are not directly transferable between the two fields of cementitious materials development, and these differences are explored and detailed in the present study.

This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

The USA and its European partners face a potential problem in accessing critical minerals. Given its implications for national security, it is important to increase supply chain resilience through diversification of sources while also establishing a basis for closer cooperation with China.

The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

The necessity to assess and manage supply chains to be free from social problems such as human and labour rights abuses has become particularly apparent since the introduction of conflict minerals regulations in the United States (Dodd-Frank Act) and the European Union. Similarly, stakeholders demand that products are free from social problems. Ever more companies are therefore challenged to assess and manage social issues in their supply chains. At the same time, the increasing literature on assessment and management of social issues is disperse and an overview missing. This paper aims to provide an overview of the existing literature on social assessment and management approaches relating to conflict minerals and connected to social issues in supply chains.

A review of the academic literature on social assessment and management of conflict minerals to provide an overview is currently missing. This paper addresses this gap by systematically reviewing the existing research literature on approaches for the social assessment and management of conflict minerals from a supply chain perspective.

The systematic literature review found 21 social assessment and 30 social management approaches with reference to conflict minerals, with the most referenced approach being the OECD guidelines. Overall, the conflict mineral related literature discusses rather general social assessment and management approaches, such as codes of conduct, while the effectiveness of the approaches is not analysed in depth. The paper finds that an analysis of the effectiveness and interlinkages of different approaches is missing. The large variety of social and human rights issues addressed in the academic literature ranges from corruption to violence, going beyond the scope of regulations focused on conflict minerals. This indicates that regulations on conflict minerals and the consequences for management are seen as a specific case with wider implications for future regulations and the necessity for management to solve social problems in supply chains in an effective way.

The review paper is conceptual and develops a framework to classify social assessment and management approaches for conflict minerals, drawing on the supply chain management literature.

The overview reveals that research refers to broader social assessment and management approaches indicating wider implications for assessing and managing social issues in supply chains in general, irrespective of whether they are conflict mineral related. Research has, however, so far not addressed the effectiveness and interlinkages between social assessment and management approaches. The aim of the emerging regulations, however, is to foster more effective management of social issues in supply chains. Management is therefore challenged to develop and implement innovative approaches to effectively reduce social problems in supply chains beyond conflict minerals. Conclusions are drawn for management and research.

The paper highlights the need for collaboration with NGOs, industry associations and suppliers, recommending to engage in supplier development.

The paper conducts the first systematic review of academic literature on conflict mineral related social assessment and management approaches. A framework is proposed to classify social assessment and management approaches based on supply chain management literature. While conflict minerals often represent a small fraction of components in a product, they can have huge and costly implications for companies, which require (potentially) large changes for the sourcing and supply strategy of a company. Conflict mineral regulations represent the first attempt to regulate social and human rights abuses in supply chains holding companies responsible for misconduct caused by suppliers abroad.

This study aims to examine the effect of traditional fermentation on gari’s total heavy metal and mineral nutrient content.

This study used a quantitative approach, descriptive-analytical design to baseline the risk of heavy metals and experimental design to assess the effect of traditional fermentation. Data were analyzed using descriptives, univariate and multivariate analysis.

Although gari is rich in mineral nutrients (total calcium 3.9 ± 0.1 g/kg, copper 5.5 ± 0.02 mg/kg, iron 97.1 ± 5.8 mg/kg, potassium 9.1 ± 0.29 g/kg and zinc 3.4 ± 0.11 mg/kg), the significant levels of heavy metals (total arsenic 1.2 ± 0.01, cadmium 2.5 ± 0.04, lead 1.7 ± 0.01, mercury 2.8 ± 0.01 and tin 1.7 ± 0.02 mg/kg) present are a cause for concern. The results further suggested that traditional fermentation has reductive effects on some heavy metals and stabilizing or concentrating effects on mineral nutrients.

This paper provides evidence that traditional fermentation may have exploitable differential effects on heavy metal contaminants and mineral nutrients that should be further explored.

Thise study reports fermentation implications for mitigating food with high heavy metal contaminants with minimal nutrient loss.

This study fulfills an identified need to optimize traditional fermentation to ensure food safety and nutrient security.

To investigate whether CO₂ intensity falls at a diminishing rate as countries grow richer.

Regression of CO₂ intensity on the gross domestic product (GDP) per capita, including squared and cubic terms, for a panel of countries and individual countries.

CO₂ intensity falls at a diminishing rate as countries grow richer.

Many studies have found that CO₂ intensity falls with GDP per capita, but whether it does so at a diminishing rate has not been investigated. This result suggests that structural changes in GDP (more services) as countries get richer will provide little or no help toward decarbonization. It is shown that the extraction of minerals critical for industrial production has increased on par with real GDP. This could explain why CO₂ emissions fall at a diminishing rate.

The purpose of this paper is to investigate the mineral content of seven Brazilian infant dairy product categories (petit Suisse cheeses, fermented milks, yogurts, fermented dairy beverage, dairy dessert, Requeijão cremoso spreadable cheese and UHT dairy beverages) and estimate their contribution to daily intake.

The composition of major (Ca, K, Mg, and Na) and trace (Pb, Cd, Cu and Mn) minerals was determined using Inductively Coupled Plasma Optical Emission Spectrometry. Furthermore, a comparative analysis of the mineral levels with the Reference Daily Intake (RDI) at different child development stages was carried out.

High Ca levels were observed in petit Suisse (3.44±1.66 mg g⁻¹), dairy dessert (3.88±0.02 mg g⁻¹) and Requeijão cremoso (4.14±0.07 mg g⁻¹). Dairy dessert presented the highest K level (2.57±0.07 mg g⁻¹), while the Requeijão cremoso presented the highest Na content (4.78±0.10 mg g⁻¹), and both products had the highest Mg contents (238.55±16.27 and 197.39±5.18 µg g⁻¹, respectively). Trace elements (Cd, Cu, Mn and Pb) were below the limit of detection for all commercial dairy foods. Among food products analyzed, petit Suisse cheese and dairy dessert can be considered good sources of calcium, while Requeijão cremoso is high in both calcium and sodium.

This study is the first to analyze the mineral levels of several Brazilian infant dairy foods and the daily intake contribution during important child development stages. These findings provide valuable guidance for researchers and practitioners trying to develop healthy and nutritious dairy products for infants and children.

We develop a conceptual framework as a basis for thinking about the impact of extractive industries and emancipatory potential of alternative accounts. We then review selected alternative accounts literature on some contemporary issues surrounding the extractive industries and identify opportunities for accounting, auditing, and accountability research. We also provide an overview of the other contributions in this special issue.

Drawing on alternative accounts from the popular and social media as well as the alternative accounting literature, this primarily discursive paper provides a contemporary literature review of identified issues within the extractive industries highlighting potential areas for future research. The eight papers that make up the special issue are located within a conceptual framework is employed to illustrate each paper’s contribution to the field.

While accounting has a rich literature covering some of the issues detailed in this paper, this has not necessarily translated to the extractive industries. Few studies in accounting have got “down and dirty” so to speak and engaged directly with those impacted by companies operating in the extractive industries. Those that have, have focused on specific areas such as the Niger Delta. Although prior studies in the social governance literature have tended to focus on disclosure issues, it is questionable whether this work, while informative, has resulted in any meaningful environmental, social or governance (ESG) changes on the part of the extractive industries.

The extensive extractive industries literature both from within and outside the accounting discipline makes a comprehensive review impractical. Drawing on both the accounting literature and other disciplines, this paper identifies areas that warrant further investigation through alternative accounts.

This paper and other contributions to this special issue provide a basis and an agenda for accounting scholars seeking to undertake interdisciplinary research into the extractive industries.

In the aftermath of the COVID-19 pandemic, supply chains have become important policy tools to ensure the security and resilience of regional trading blocs of major economies. The US government’s focus on supply chains for selected strategic industries and the EU Commission’s renewed efforts to strengthen its supply chains using ‘sustainability standards’ coincides with the global trend in the shift towards digital and low-carbon economies. Furthermore, the rising tensions between the US and China, with no signs of reconciliation over key issues of contention, have emphasized the need for more credibility and trust in global supply chains. However, such policies also have the potential to serve as new barriers to participation in supply chains by less-developed economies which are not yet prepared to meet the high-level sustainability criteria which aim for higher protection of the environment and labor rights. There also seems to be an apparent shift in paradigm supporting the interventionist role of government that emphasize the need for more discretion for policy objectives that pursue societal and democratic values, not to mention national security interests. The current rules of international trade, however, do not sufficiently address these new issues and need to be realigned in order to meet the new demands. The current ‘rules of the game’ need to be reinforced in order to accommodate the rising need of countries for increased consideration of issues of sustainability and competitiveness.
