Electroless nickel deposition (ELD) is an autocatalytic technique extensively used to impart conductive, protective, and mechanical functionalities to inherently non-conductive synthetic substrates. This review systematically explores the fundamental mechanisms of electroless nickel deposition, emphasising recent advancements in surface activation methods, solvent systems, and microstructural control. Critical analysis reveals that bio-inspired activation methods, such as polydopamine (PDA) and tannic acid (TA), significantly enhance coating adhesion and durability compared to traditional chemical etching and plasma treatments. Additionally, solvent engineering, particularly using polar aprotic solvents like dimethyl sulfoxide (DMSO) and ethanol-based systems, emerges as a key strategy for achieving uniform, dense, and flexible coatings, overcoming limitations associated with traditional aqueous baths. The review also highlights that microstructural tailoring, specifically the development of amorphous-nanocrystalline hybrid nickel coatings, effectively balances mechanical robustness (hardness exceeding 800 HV), flexibility, and corrosion resistance, making these coatings particularly suitable for wearable electronic textiles and smart materials. Furthermore, commercial examples demonstrate the real-world applicability and market readiness of nickel-coated synthetic fibres. Despite significant progress, persistent challenges remain, including reliable long-term adhesion, internal stress management, and environmental sustainability. Future research should prioritise environmentally benign plating baths, standardised surface activation protocols, and scalable deposition processes to fully realise the industrial potential of electroless nickel coatings.

Concentration within the food industry is a desirable process in the context of improving economic efficiency, which is the basis for building sustainable competitive advantages in internationalisation and globalisation. Excessive concentration of market structures can generate negative externalities that threaten sustainability in the long term. Maintaining a balance between the freedom of economic activities and the protection of consumers and environmental interests is fundamental to the stability of the entire economy and its position in the international market, which is a priority of the EU-MERCOSUR trade agreement. The aim of this article was to assess the process of concentration of the Polish food industry and its impact on factor efficiency in the context of changing external conditions. In order to do so, the Cobb–Douglas production function was used. The research results showed that there is a progressive concentration in the food industry. Changes in the entity structure are taking place in an evolutionary way, as illustrated by the still high fragmentation of companies. Large companies make good use of economies of scale, which is mirrored in their high efficiency. The structure of the Polish food industry makes it possible to realise the objectives of agricultural policy, including in terms of sustainable development and improvement of competitiveness on the global market. Taking into account the current entity structure of the Polish food industry, it will be crucial for the long-term sustainability to take into account contemporary economic, environmental and social issues in the EU-MERCOSUR trade agreement.

Several studies have demonstrated that 3D-printed geopolymer concrete (3DPGPC) could be a sustainable solution to minimising waste, carbon emissions, and production costs, thereby providing quick completion of construction projects. However, for 3DPGPC to be widely adopted, it is essential to be aware of both the prospects as well as the limitations. In this regard, the scope of this perspective article includes a review of the limitations of 3DPGPC. Key limitations regarding the material, structural, technical, economic, and environmental aspects of 3DPGPC are highlighted. Additionally, this article includes the general limitations associated with geopolymer concrete. As such, geopolymer concrete suffers from several problems owing to varying alkaline activators and precursor types while exhibiting performance variability even within the same type of precursor. These limitations need to be addressed first in order to make progress in 3DPGPC. Following the limitations, this article then presents the research priorities in 3DPGPC, such as the need for a standardised code for its adoption in infrastructure projects. Hence, the information presented in this article is timely and crucial for all stakeholders in the low-carbon community. Furthermore, it serves as a call for future research to overcome the discussed limitations to realise the full potential of 3DPGPC technology. Full article

This contribution examines the human rights framework and legislative developments in South Africa on persons with mental illness, revealing that the initial focus of the legislation was on control and detention at the cost of the rights of mental health care users. Presently, under its Constitutional democracy, South Africa has progressive Mental Health Legislation focusing on the rights of mental health care users and the least restrictive means of treatment. The contribution considers the impact of the legislative developments on the human rights of mental health care users. There are, however, challenges with the implementation of the legislation most notably illustrated by the Life Esidimeni disaster where a mass deinstitutionalization project led to the loss of life. South Africa’s revised Mental Health Policy Framework holds a renewed commitment to respect a mental health care user’s right to dignity, integrity, privacy, and freedom of movement. This is one step closer to the realisation of the obligations created by the United Nations Convention on the Rights of Persons with Disabilities (CRPD). The contribution considers the 2018 concluding observations by the United Nations Committee on the Rights of Persons with Disabilities, which lays bare areas where yet further improvement is needed in South Africa to eradicate all forms of discrimination against persons with disabilities and, in particular, persons with mental illness Areas where progress have been made are highlighted. South Africa has made steady progress but needs to intensify its efforts to domesticize the CRPD. Full article

With the rapid development of technological progress and smart city construction, the concept of sustainable cities is gradually being integrated into all aspects of urban construction. In this context, the public’s demand for high-quality and rich leisure experiences is increasing, and the design, management, and service standards of urban parks are also being upgraded. As an innovative product of the integration of ecological civilisation and information technology, smart interactive parks have become an important direction for promoting sustainable urban development, especially in the landscape design of waterside parks, which show unique significance. This study explores the application of the smart interactive concept in the landscape design of waterside parks from the perspective of sustainable cities, aiming to construct a set of evaluation frameworks to assess its effectiveness and value in urban development. Through in-depth analyses of the smart interaction concept and its application in landscape design, this study combines environmental psychology, landscape ecology, and GIS technology to propose innovative goals, strategies, and design methods for waterside smart interactive landscapes that can support the ecological and social needs of sustainable cities. Domestic and international case studies show that the successful application of smart interactive technologies in waterside parks not only improves environmental quality but also promotes economic development by enhancing the attractiveness of the parks, providing multiple values for sustainable cities. In the empirical research section, this paper takes Haeundae Waterside Park in South Korea as the object of investigation and constructs a design framework based on project selection and indicator quantification to further validate the effectiveness of the practical application of the smart interactive concept in waterside park landscape design. Based on the findings, this paper proposes a series of policy recommendations to promote the construction of smart interactive parks and sustainable urban development. These recommendations not only provide theoretical support for the future development of Haeundae Waterside Park but also provide a reference for the design and planning of public spaces in other cities around the world. By promoting the integration of smart interactive concepts with ecological sustainability, this study provides an innovative reference path for urban planners, landscape architects. and environmentalists to help realise the goal of a sustainable city with coordinated ecological, social, and economic development.

Over the past decade, an increasing number of oncology medicines with indications for multiple cancer types have been delivering benefits to patients. To ensure these products reach patients, pricing and reimbursement systems have had to adapt to address the value assessment, time-to-access, affordability, and budget uncertainty challenges this creates. Multi-year multi-indication (MYMI) agreements are made between payers and manufacturers and aim to ensure that patients have access to effective treatments for multiple conditions over time; this includes future indications of the treatment. MYMI agreements were first introduced as a solution in several European countries in 2017, offering a range of potential benefits. MYMI agreements have since demonstrated evidence of success in mitigating many of the challenges associated with assessing and reimbursing multi-indication products, time-to-patient access, and budget impact. The purpose of this article is to discuss the recent progress made with MYMI implementation across countries and provide a view on whether it is delivering for patients, healthcare systems, and innovators. We find that MYMI is not a one-size-fits-all solution but a model that needs to be adapted to the unique needs and characteristics of different healthcare systems. The intended benefits of MYMI to patients (speed and breadth of access to new indications) appear to have been realised in practice in some countries but not all. However, the administrative burden associated with MYMI implementation in some countries risks jeopardising the intended efficiency benefits. Payers and policymakers can also benefit from improved budget predictability and sustainability. Full article

It is widely recognised that addressing inequality in tertiary education is a complex and multifaceted issue. Studies involving students from lower socio-economic backgrounds consistently show that educational disparities exist at the post-secondary education level, with these students’ encountering obstacles in both accessing and completing tertiary education compared to their wealthier counterparts. Understanding how widening participation interventions may influence young people’s post-compulsory education is an important part of addressing the participation gap. This paper investigates longitudinal data from 227 students in Dublin, Ireland, who were attending post-primary schools located in areas that have low progression to tertiary education. The paper examines the extent to which students’ post-secondary plans, formulated in their final year of secondary school, are realised six months after graduation. The paper continues to examine the influence of external interventions provided by an Irish university’s widening participation (WP) programme on secondary school students’ progression to post-compulsory education. Taking into account contextual factors (e.g., gender, ethnicity, school type, parental education, parental support), this paper examines how WP programmes in secondary school impact post-school progression. Programme engagement (guidance outreach activities) was associated with 4.91-greater odds of post-secondary education once other contextual factors had been controlled for. Participating in mentoring programmes did not have a significant influence on post-secondary progression. Findings in relation to these are discussed, and recommendations for how practitioners and policy makers can approach widening participation outreach programmes with secondary school students are highlighted.

As we progress towards Industry 5.0, technological advancements are converging; this movement is realised by the increasing collaboration between humans and intelligent digital platforms and further enabled by the interactive visualisation modes provided by Metaverse technology. This research examines the practical applications and limitations of Metaverse technology providing insights into the transformative possibilities it offers for the manufacturing sector. Specifically, the research was guided by the core objective to trace the evolution of Metaverse technology within manufacturing. This study provides a comprehensive and state-of-the-art analysis of the adoption and impact of Metaverse technologies in the manufacturing sector. While previous research has explored aspects of Industry 4.0 and digital transformation, this study specifically focuses on human-centric manufacturing (human-in-the-loop) applications of Metaverse technology, including augmented reality, virtual reality, digital twins, and cyber-physical robotic systems. Findings from the systematic literature review indicate that Metaverse technologies, primarily augmented reality and virtual reality, have evolved into powerful tools in manufacturing. They are widely adopted across sectors in the industry, transforming processes such as product design, quality control, and maintenance. Augmented reality and virtual reality offer intuitive ways to visualise data and interact with digital twins, bridging the gap between physical and virtual realms in manufacturing. A roadmap and scenarios for the introduction of Metaverse technology in manufacturing are provided with suggested adoption timespans. Furthermore, the systematic literature review identified barriers hindering the wider adoption of Metaverse technology in manufacturing. Full article

Two identically sized RC beams were fabricated to investigate the effects of explosive loads on the flexural behaviour of Reinforced Concrete (RC) beams. One of the beams was subjected to an explosive load to induce post-explosion damage, and subsequently, both beams underwent flexural capacity testing. Integrating piezoelectric smart aggregates (SAas) within the beams facilitated continuous observation of the damage conditions, allowing for the assessment of internal concrete deterioration from explosive impacts to bending failures. The internal crack development index R was established using the Wavelet Packet Energy Analysis method. Combined with the structure’s residual capacity-based damage assessment criterion, the relationship between R and component damage was found. This allowed us to identify the change in the bending capacity of RC beams after explosion damage and the quantitative damage assessment of the beam to be realised, providing valuable insights for structural engineers and researchers. Comparing the flexural test results between the explosively pre-damaged beam and the undamaged test beam, it was observed that the neutral axis of the damaged beam was significantly elevated, accompanied by a notable reduction in flexural capacity. By examining the variation curve of the internal crack development index R, it was noted that during the initial stage of the bending flexural test, due to bending deformation, cracks in the core region of the pre-damaged beam gradually healed, leading to a pseudo-decrease in the damage index. After reaching a minimum point, the damage progressed faster until failure occurred. Full article

Currently, modern hydrogen technologies, due to their low or zero emissions, constitute one of the key elements of energy transformation and sustainable development. The growing interest in hydrogen is driven by the European climate policy aimed at limiting the use of fossil fuels for energy purposes. Although not all opinions regarding the technical and economic potential of hydrogen energy are positive, many prepared forecasts and analyses show its prospective importance in several areas of the economy. The aim of this article is to provide a comprehensive review of modern materials, current hydrogen technologies and strategies, and show the opportunities, problems, and challenges Poland faces in the context of necessary energy transformation. The work describes the latest trends in the production, transportation, storage, and use of hydrogen. The environmental, social, and economic aspects of the use of green hydrogen were discussed in addition to the challenges and expectations for the future in the field of hydrogen technologies. The main goals of the development of the hydrogen economy in Poland and the directions of actions necessary to achieve them were also presented. It was found that the existence of the EU CO₂ emissions allowance trading system has a significant impact on the costs of hydrogen production. Furthermore, the production of green hydrogen will become economically justified as the costs of energy obtained from renewable sources decrease and the costs of electrolysers decline. However, the realisation of this vision depends on the progress of scientific research and technical innovations that will reduce the costs of hydrogen production. Government support mechanisms for the development of hydrogen infrastructure and technologies will also be of key importance. Full article

Artificial intelligence (AI) has found applications in enterprises′ production planning processes. However, a critical question remains: could AI replace human planners? We conducted a comparative analysis to evaluate the main task of planners in an intermittent process: planning the duration of production orders. Specifically, we analysed the results of a human planner using master data and those of an AI algorithm compared to the actual realisation. The case study was conducted in a large production company using a sample of production products and machines. We were able to confirm two of the three research questions (RQ1 and RQ3), while the results of the third question (RQ2) did not meet our expectations. The AI algorithms demonstrated significant improvement with each iteration. Despite this progress, it is still difficult to determine the exact threshold at which AI outperforms human planners due to the unpredictability of unexpected events. Even though AI significantly improves prediction accuracy, the inherent variability and incomplete input data pose a major challenge. As progress is made, robust data collection and management strategies need to be integrated to bridge the gap between the potential of AI and its practical application, fostering the symbiosis between human expertise and AI capabilities in production planning.

This article explores the question of the rate of digital progress in the context of the labour market. Specific features of the current situation are discussed: the temporality of socio-technological transformations, which is becoming less and less compatible with the harmonious development of man and society; the pace at which machines acquire intelligence; the total devaluation of mental labour; the unresolved issue of the role of man in the world of intelligent machines; and the criticality of the problem of the labour market due to its global nature, social significance and the rate of socio-technological changes. It is emphasised that these circumstances, already in the short term, threaten the sustainable development of global society, whose reactions to the transformation of technological and socio-economic infrastructure are significantly lagging behind. It is concluded that there is an urgent need to strengthen social responsibility, determined by the new ethics of relations between humans and machines with AI, supplemented by the primacy of the dignity of the social role of humans. The authors point out the urgent need to revise ideas about work as the main purpose of a person and about realisation in the profession as the main factor that determines the self-esteem of an individual and his social status.

This study adds to the existing literature on the history of the Ghanaian press from pre-colonial times to 1992, focusing on language: its choice and ideological, socio-cultural, and political ramifications. While the history of the press has received massive scholarly attention, the same cannot be said of language and its use in historical accounts. Thus, from a historical research perspective, employing an analytical and interpretive study of secondary data sources, and underpinned by cultural theories such as linguistic imperialism and hegemony, this study analyses how language was featured in the press during the research period and the implications thereof. This analysis shows that various institutions and individuals exploited language to foster narrow socio-cultural, ideological, and political agendas in the Gold Coast, later Ghana. This study also revealed that language use and its ideological forces during the pre- and immediate post-independence periods contributed immensely to Ghanaian media’s current state and Ghanaians’ general language attitudes. This study’s significance lies in the realisation that language, as a cultural artifact, and its choice, use, and consumption could have far-reaching consequences for the self-realisation, actualisation, and general progress of a society. Thus, African societies should be mindful of the ideological implications of language choices not just in the press but also in other societal contexts. This study, therefore, invites further studies on language and its use in the media, especially from 1992, for a more comprehensive appreciation of the issues raised in this study. Full article

It is widely recognised that improving the visibility and controllability of distributed energy resources (DERs) within electricity distribution networks will have significant benefits, particularly for the management of low-voltage (LV) and medium-voltage (MV) networks. Much work within the electricity distribution industry is currently focused on improving the visibility of DERs on LV networks. From a control-theoretic perspective, this enables closing the loop between the DER and the control room and enables a shift towards utilising data-driven model-based control strategies for DERs. The result is a system-wide performance that is closer to the theoretical optimal. In the Australian context, several jurisdictions are trialling techniques such as dynamic operating envelopes to enhance DER hosting capacity, using IEEE 2030.5-based architectures, with the implementation of distributed energy resource management (DERMS) systems at the enterprise level still quite limited. While there is significant activity focused on DER behaviour and control techniques by way of inverter grid codes and standards, the core issue of interoperability with distribution management systems (DMSs), market operators or participants, electric vehicles (EVs) or other DERs is still a work in progress. Importantly, this is also an impediment to realising distributed architectures for DER control in the grid. The unique characteristics of Australian distribution networks highlights several challenging problems for DER control and management. The objective of this paper is to provide a broad overview of DER control and management strategies in the Australian context, with an application focus on DER control in distribution network management.

Ships are important targets for modern naval warfare detection and reconnaissance. The accurate detection of ships contributes to the maintenance of maritime rights and interests and the realisation of naval strategy. Synthetic Aperture Radar (SAR) image detection tasks play a vital role in ship detection, which has consistently been a research hotspot in the field of SAR processing. Although significant progress has been achieved in SAR ship detection techniques using deep learning methods, some challenges still persist. Natural images and SAR images significantly diverge in imaging mechanisms and scattering characteristics. In complex background environments, ships exhibit multiscale variations and dense arrangements, and numerous small-sized ships may be present, culminating in false or missed detections. To address these issues, we propose a novel SAR ship detection network, namely, a Wavelet-Driven Feature-Enhanced Attention–You Only Look Once X (WDFA-YOLOX) network. Firstly, we propose a Wavelet Cascade Residual (WCR) module based on the traditional image processing technique wavelet transform, which is embedded within an improved Spatial Pyramid Pooling (SPP) module, culminating in the formation of the effective wavelet transform-based SPP module (WSPP). The WSPP compensates for the loss of fine-grained feature information during pooling, enhancing the capability of the network to detect ships amidst complex background interference. Secondly, a Global and Local Feature Attention Enhancement (GLFAE) module is proposed, leveraging a parallel structure that combines convolutional modules with transformer modules to reduce the effect of irrelevant information and effectively strengthens valid features associated with small-sized ships, resulting in a reduction in false negatives in small-sized ship detection. Finally, a novel loss function, the Chebyshev distance-generalised IoU loss function, is proposed to significantly enhance both the precision of the detection box and the network convergence speed. To support our approach, we performed thorough experiments on the SSDD and HRSID, achieving an average precision (AP) of 99.11% and 96.20%, respectively, in ship detection. The experimental results demonstrate that WDFA-YOLOX has significant advantages in terms of detection accuracy, generalisation capability, and detection speed and can effectively realise more accurate detection in SAR images, consistently exhibiting superior performance and application value in SAR ship detection.
