In many energy policies, including Poland’s, environmental priorities clash with the issue of energy security. With these contradictions in mind, the main objective of the article is a comparative analysis of domestic production and imports of hard coal in Poland and the formulation of conclusions for energy policy and competitiveness. The analysis covers the years 2018–2023 and concerns three issues: the volume and directions of coal imports to Poland, the qualitative and price competitiveness of coal, and the possibility of substituting imported coal with domestic coal. The research used statistical analysis. Indicators of structure and dynamics as well as comparative analysis were also used. The analysis shows that the structure of coal importers to Poland is quite diverse and includes many geographic directions. However, until 2021, it was dominated by Russia, followed by Colombia, indicating a fairly homogeneous supply market and a continuing tendency to depend on a single importer. Analysis of qualitative competitiveness confirms the existence of balance and industrial resources whose quality parameters (sulfur content, ash content, and calorific value) are comparable to and better than those of imported coal. Polish hard coal can also compete with imported coal in terms of price. From 2021 to 2023, it was clearly cheaper than foreign coal. In the above circumstances, it is quite difficult to unequivocally assess the reasons for importing coal to Poland and to justify dependence on external suppliers. This is especially relevant since domestic mining in 2020–2023 remains stable (periodically even increasing), which does not indicate a decisive shift away from coal as an energy resource.

This article explores the pervasive influence of conspiracy theories, specifically the New World Order (NWO) and Golden Billion theories, within the context of the ongoing conflict between Russia and Ukraine. These theories form key narrative frameworks in Russian state media and global conspiracy communities, shaping perceptions of geopolitical events. This study dissects four pivotal episodes within the Russia–Ukraine conflict to illustrate how conspiracy theories shape public perception and policy direction, further entrenching ideological divides. In the first episode of the 2022 full-scale invasion, narratives of the Golden Billion were utilised to justify the attack, presenting Russia as a bastion against the Western elite’s plans to dominate the global economy and resources. The second episode examines the attack on Mariupol in 2022, framed by Russian propaganda as a necessary act to thwart the supposed expansion of NATO and the EU, underpinned by the NWO agenda aiming to dilute Russian influence in Eastern Europe. The third episode analyses the Nord Stream pipeline sabotage in 2022, interpreted by some conspiracy theorists as an act by the NWO to destabilise Europe’s energy security, thus consolidating control over energy routes and resources. The fourth episode delves into the 2024 Moscow terrorist attacks, which were seen by some as either a false flag operation conducted by Western powers or as a legitimate repercussion of Western encroachment orchestrated to weaken Russia’s resolve and international standing. Each episode is contextualised within a broader conspiratorial framework, highlighting the dualistic nature of the NWO and Golden Billion theories that paint the conflict not merely as territorial disputes but as a clash between fundamentally opposing worldviews and global orders. This narrative analysis not only underscores the role of conspiracy theories in shaping geopolitical discourse but also demonstrates their utility in mobilising domestic support, framing international criticism, and justifying military actions. Our findings suggest that these conspiratorial narratives provide a resilient, albeit misleading, lens through which supporters of the Kremlin’s policies can rationalise the war, attributing complex sociopolitical dynamics to the malevolent machinations of a global elite. This study contributes to understanding how modern conflicts are interpreted through ancient conspiratorial lenses, impacting national and international policy and public opinion. Full article

This article investigates the relationship between Sustainable Development Goal 4 (SDG 4), academic integrity as its part, and artificial intelligence (AI) through a bibliometric analysis, assessing whether this intersection represents a clash or win-win cooperation. SDG 4 aims to ensure equitable access to quality education, while AI technologies have the potential to enhance educational practices but demote academic integrity. By analyzing a comprehensive body of the literature, this study identifies key trends and thematic areas where AI is applied in educational settings, particularly concerning maintaining academic integrity. The findings reveal a growing body of research highlighting AI’s role in personalizing learning experiences, improving educational accessibility, and supporting educators’ teaching methodologies. However, challenges such as ethical considerations, data privacy, and the digital divide are also addressed, indicating potential conflicts that need to be navigated. Ultimately, this analysis suggests that while there are significant opportunities for synergy between AI and SDG 4, the management of careful implementation and policy frameworks is essential to ensure that AI serves as a tool for promoting inclusive and sustainable education rather than exacerbating existing inequalities. AI transforms science management by enhancing data analysis, streamlining research processes, and improving decision-making, ultimately leading to more efficient and effective scientific research and innovation. The findings reveal that while AI can facilitate personalized learning and enhance educational accessibility, it also poses challenges related to academic misconduct, such as plagiarism and the misuse of AI-generated content. This duality highlights the need for educational institutions to develop robust frameworks that leverage AI’s capabilities while safeguarding academic integrity. The article concludes that a collaborative approach, integrating AI into educational practices with a strong emphasis on ethical considerations and integrity, can lead to a synergistic relationship that supports the goals of SDG 4. Recommendations for future research and practical implications for managers, educators, scientists, and policymakers are also discussed, emphasizing the importance of fostering an educational environment that embraces innovation while upholding ethical standards.

The rapid increase in population and economic activities has greatly influenced land use and spatial development. In urban agglomerations where socioeconomic activities are densely concentrated, the clash between ecological protection and economic growth is becoming more evident. Therefore, a thorough quantitative assessment of spatial changes driven by land use dynamics, alongside an examination of temporal and spatial driving factors, is crucial in offering scientific backing for the long-term and sustainable growth of urban agglomerations. This paper focuses on the major urban agglomerations in China’s Yangtze River Delta region, examining the spatiotemporal evolution of land use and landscape patterns from 2000 to 2020. By employing the standard deviation ellipse technique, coupled with multiple linear regression and the geographical detector model, we conduct a quantitative assessment of the directional trends in urban construction land expansion as well as the diverse impacts of temporal and spatial factors on this expansion across various periods and regions. The findings indicate that over the past 20 years, construction land in the Yangtze River Delta Urban Agglomeration expanded in concentrated patches, showing significant scale effects with relatively intact farmland and forest land being increasingly encroached upon. Landscape-type transitions predominantly occurred in cities around Taihu Lake and Hangzhou Bay, with the most significant transition being farmland converted to construction land, resulting in a greater number of patches and more pronounced land fragmentation. Throughout the 20 years, the standard deviation ellipse of construction land in the Yangtze River Delta Urban Agglomeration expanded and shifted, with the predominant expansion trending from the northwest toward the southeast, and the EN orientation being the most intense expansion area, covering 1641.24 km². The influence of temporal and spatial driving factors on the expansion of urban construction land differed across various periods and regions. This study thoroughly examines the driving factors that affect the evolution of urban construction land in the region, offering valuable scientific evidence and references for future planning and development of the Yangtze River Delta Urban Agglomeration, aiding in the formulation of more precise and efficient urban management and land use strategies.

Background: An increase in plant-sourced (PS) nutrient intake is promoted in support of a sustainable diet. PS dietary minerals and proteins have bioactive properties that can affect bone health and the risk of fracture. Methods: In a group randomised, cross-over design, this study evaluated the post-ingestion temporal pattern of change in arterialised ionised calcium (iCa), parathyroid hormone (PTH), C-terminal crosslinked telopeptide of type I collagen (CTX) and procollagen type 1 amino-terminal propeptide (P1NP) for 4 h following ingestion of a novel supplement (SUPP) containing a PS marine multi-mineral + PS protein isolate. A diurnally matched intake of mineral water was used as a control (CON). Results: Compared to baseline, the change in iCa concentration was 0.022 (95% CI, 0.006 to 0.038, p = 0.011) mmol/l greater in SUPP than CON, resulting in a −4.214 (95% CI, −8.244 to −0.183, p = 0.042) pg/mL mean reduction in PTH, a −0.64 (95% CI, −0.199 to −0.008, p = 0.029) ng/mL decrease in the biomarker of bone resorption, CTX, and no change in the biomarker of bone formation, P1NP. Conclusions: When used as a dietary supplement, or incorporated into a food matrix, the promotion of PS marine multi-mineral and PS protein isolates may contribute to a more sustainable diet and overall bone health.

Rising urban temperatures, noise and air pollution, and the loss of biodiversity are pressing problems in cities worldwide that call for action at different scales to improve the livability of urban areas. This study focuses on the role that buildings and façade design play in the urban environment, exploring how their informed design might help mitigating these environmental issues at a local scale. It explores the field by means of a systematic review aimed at identifying the impact of façade design choices focusing on three main design variables: material, geometry, and vegetation in façades. Scopus and Web of Science databases were explored between 17 April and 20 April 2023, ending up with 121 scientific articles, then categorized and data-mined to allow for descriptive statistical analysis to discuss scientific results obtained via digital simulation or empirical measurements. Risk of bias was addressed through double revision of the gathered sample. This study ends with the identification of desirable façade attributes based on their reported impacts, in terms of material properties, geometric operations, and main vegetation parameters, which we discuss by outlining compatibilities and clashes between them to guide conscious building design decisions to improve the urban ecosystem.

This article examines a distinctive and debated social group called the “Baboos” in late colonial India, particularly in Bengal. The Baboos represented the Western-educated, aspiring middle class who were integral to the British administration. They were often viewed skeptically for adopting the English language and Western lifestyle. This study delves into the quotidian lives of the Baboos, particularly their interactions with the colonial rulers in public transport, which became a crucial contact zone. Despite facing racial conflicts and discrimination in these shared spaces, the Baboos were not passive victims. They used diverse strategies to combat injustices and voice their grievances publicly. Within this larger narrative of discriminating treatment, another power narrative was played out by the Baboos among their own population. Conscious of their distinct functional status, the Baboos sought to distance themselves from those Indians who did not match their ideas of “respect”. Everyday experiences formed the basis of the public outrage reflected continually in regional newspapers and, subsequently, in the larger narratives of resistance and nationalism. How the Baboos negotiated their position in the public spaces sheds light on their claims of civil rights and their ways of using the colonizer’s tropes of equality, justice, and fairness back at them.

This study aims to explore the issues of Islamophobia and Christian ideology prevalent in Spanish society in the 16th and early 17th centuries by examining the slave trade conducted by Barbary corsairs and the hard lives of Christian captives depicted in the literary works of Miguel de Cervantes, and to highlight his efforts to overcome the clash of civilizations between Christianity and Islam. To achieve this goal, first, the study delves into the historical context of the clash between Spain and Islam in the Mediterranean during the 16th century. Cervantes, who took part in the Battle of Lepanto in 1571, was captured by Barbary corsairs on his return from military service and spent five years as a captive in the Bagnio of Algiers. The painful experience left indelible marks on his works. This study focuses on the dual meaning of Orientalism in his works. One prevalent form of Orientalism in Spain and Europe during that period portrayed Muslims as barbaric and anti-Christian. However, Cervantes presented an alternative Orientalism to propose a pathway to co-existence, rather than conflict, between civilizations and religions. Therefore, this study explores how Cervantes, even though he himself was a victim of the clash of civilizations, sought to overcome the confrontations and conflicts in his works, rather than perpetuating the prevalent Islamophobia of his time.

This study explores the ethical dilemmas in contemporary Igbo Christian marriages as couples navigate the interaction between modernity and cultural identities. Marriage in traditional Igbo society is entrenched in strong cultural and religious values. However, Christianity and modernity have brought new dynamics to this institution in contemporary times. This paper, therefore, examines the influence of Christianity and modernity on Igbo traditional marriage, discussing ethical dilemmas arising from these influences. It specifically addresses areas where the traditional Igbo practices often clash with Christian doctrine and modern ideals, such as Igbo communalism, gender roles, family obligations, and marital expectations. The study also highlights strategies for resolving these dilemmas, including effective communication, cultural adaptability, and external support systems. Utilising a qualitative case study and descriptive–analytical methods, the research provides invaluable insights into the emerging dilemmas in Igbo marriage, offering a nuanced understanding of how individuals and communities can navigate these ethical complexities in a fast-shifting world. This work contributes to the broader discussions on cultural identities, religious practices, and ethical challenges in modern times. Full article

Performing risk assessments in construction requires collecting and analyzing project data and historical safety accident data, which is challenging due to the inherent complexities and dynamic nature of construction projects. To address these challenges, building information modeling (BIM) has been leveraged as a centralized digital repository that integrates data and provides a holistic 3D view of a project. Previous studies have highlighted BIM’s significant functions for risk assessment, such as visualization, simulation, and clash detection. However, these studies often overlook the incorporation of temporal information, which is crucial for assessing risks accounting for the dynamic conditions of construction sites. This study develops a 4D BIM-based risk-assessment framework by integrating spatial and temporal data to respond to dynamic site changes. The framework leverages 4D BIM to combine 3D model data with time-, resource-, and logistics-related information, enhancing the tracking and evaluation of construction progress. The study involves investigating major construction accidents, classifying their risk factors, establishing risk-factor identification algorithms, and implementing the framework on a web-based platform for validation. This approach offers a comprehensive risk-identification strategy, applicable to multiple accident types, with intuitive visualization using BIM models, benefiting from managers’ experiential knowledge and enabling effective risk assessments and mitigation strategies. Consequently, potential safety risks at construction sites can be efficiently identified using interconnected spatial and temporal data while tracking changes in risk levels in real time and visualizing them on a web-based platform.

Ample scholarship thoroughly documents how modern humanitarian aid enacts legacies of colonialism and processes of Westernization through the imposition of foreign values and promotion of ‘universal’ norms. Extensive research has also explored processes of socio-cultural-moral transformation due to crisis and displacement. This paper extends this work by demonstrating an explicit connection between the two. Drawing on 10 months of ethnographic research that examined how Burundian refugees in Tanzania experience humanitarian social emotional learning (SEL), findings reveal various intersecting lines of crisis in the Nduta refugee camp. This research illuminates how SEL interacts with these lines of crisis to exacerbate intergenerational tensions. The self-centric values promoted through SEL and the pedagogies it employs conflict with the collectivist ethos of the Nduta community, thus breaking the Burundian generational contract of reciprocity, solidarity, and moral responsibility. In this context, SEL operates on conflicting narratives of crisis that clash with generational hopes for the prevention of future crisis in Burundi. These generational fractures are resulting in fears across the Nduta community that the decline of traditional Burundian values and communitarian ethos will not only perpetuate intergenerational experiences of crisis but has also initiated the perceived erasure of their culture and the essence of their humanity.

The inclusion of rumen buffers in ruminant feeds has gained widespread adoption for the prevention of rumen acidosis, thereby avoiding the negative production and health consequences of low rumen pH and resulting in improved feed efficiency. Benchmarking and quality controlling the performance of rumen buffer materials is of significant interest to feed mills and end-user producers. The aim of this study was to evaluate, develop and optimise a laboratory protocol to consistently and robustly evaluate rumen buffering materials in order to predict their in vivo efficacy. Three different methods were evaluated for determining the buffering potential of carbonate buffer materials: (a) 2 and 8 h static pH, (b) 8 h fixed HCl acid load addition and (c) 3 h acidotic diet simulation using acetic acid. Buffer material, threshold pH, test duration and interactions between all three variables were significant (p < 0.001) in evaluating the performance of the buffer materials. The acidotic diet simulation was found to provide a different ranking of materials to the 8 h fixed HCl acid load methodology. The results highlight the importance of method selection and test parameters for accurately evaluating the potential efficacy of rumen buffer materials. Full article

Building information modelling (BIM) is an appreciated technology in the field of architecture and construction management. Collaboration of information in BIM has not been fully utilized in the structural engineering stream as many engineers keep on working with previous prevailing design approaches. Failure to adequately facilitate automation in design could lead to structural defects, construction rework, or even structural clashes, with major financial implications. Given the inherent complexity of large-scale construction projects, the ‘manual design and detailing’ of structure is a challenging task and prone to human errors. Against this backdrop, this study developed a 4D building information management approach to facilitate automated structural models for professionals designing all the elements required in reinforced concrete (RC) structures like slabs, beams, and columns. The main contribution of this study is to obtain structural models directly from architecture models automatically, which reduces effort and possible errors in the previous prevailing approaches. The framework enables execution of all the model design works automatically through coding. This is achieved by executing a script which is beneficial for integrated project delivery (IPD). The 3D structural model in BIM software presented in this study extracts and transfers the geometrical data and links these data in Industry Foundation Classes (IFC) files using integration facilitated by Python 3.6 and IFCopenshell. The developed automated programme framework offers a cost-effective and accurate methodology to address the limitations and inefficiencies of traditional methods of structural modelling, which had been carried out manually. The authors have developed a novel tool to extract structural models from architectural models without proprietary software, greatly benefiting BIM managers by enhancing 3D BIM models. This advancement toward Open BIM, crucial for the architecture, engineering, and construction (AEC) industry’s future, is accessible to educators and beginners and highlights BIM’s effectiveness in improving structural analysis and productivity. The core finding of this study is to generate a structural model from an architecture model by automating the script with Python integration of IFC and IFCopenshell. The merits of the developed framework are reduced clashes, more economical structural modelling, and fully automated smart work as functions of the IPD. Full article

Like many coastal lagoons in several countries, the “Navío Quebrado” lagoon (La Guajira, Colombia) is a very delicate and precious environment; indeed, it is a nationally recognized Flora and Fauna Sanctuary. Several factors, including climate change, are threatening its existence because of changes in the governing hydro-morphological and biological processes. Certainly, the first step to addressing this problem is to understand its hydrological behavior and to be able to replicate, via simulation, its recent history before inferring likely futures. These potential futures will be marked by changes in the water input by its tributary, the Camarones River, and by modified water exchange with the sea, according to a foreseen sea level rise pattern, as well as by a different evaporation rate from the free surface, according to temperature changes. In order to achieve the required ability to simulate future scenarios, data on the actual behavior have to be gathered, i.e., a monitoring system has to be set up, which to date is non-existent. Conceptually, designing a suitable monitoring system is not a complex issue and seems easy to implement. However, the environmental, socio-cultural, and socio-economic context makes every little step a hard climb. An extremely simple—almost “primitive”—monitoring system has been set up in this case, which is based on very basic measurements of river flow velocity and water levels (river, lagoon, and sea) and the direct participation of local stakeholders, the most important of which is the National Park unit of the Sanctuary. All this may clash with the latest groovy advances of science, such as in situ automatized sensors, remote sensing, machine learning, and digital twins, and several improvements are certainly possible and desirable. However, it has a strong positive point: it provides surprisingly reasonable data and operates at almost zero additional cost. Several technical difficulties made this exercise interesting and worthy of being shared. Its novelty lies in showing how old, simple methods may offer a working solution to new challenges. This humble experience may be of help in several other similar situations across the world. Full article

Background: Format readability, including font and spacing, impacts reading metrics in adults, but will the research generalize to children? We examined how eight fonts (four serif and four sans serif) and three-character spacing variations influenced children’s reading comprehension and reading speed. Methods: Fifty-one students in third–fifth grade read 11 narrative text passages on a computer and answered comprehension questions. Passages were randomized in terms of order. First, the font in which the text of each passage was presented was manipulated. Then passages were presented in three spacing manipulations (narrow, normal, and wide). Results: A linear mixed effects model demonstrated that, on a group-level, passages presented in Roboto and Arial font were read significantly faster (words-per-minute) than other fonts. On the individual level, students experienced significant boosts in reading speed (words-per-minute) between their best and worst fitting font, and spacing. A chi-square test showed no one font or spacing setting that was most likely to be a students’ font fit or clash. For reading comprehension, no speed–comprehension tradeoff was observed. Conclusions: Changes to text format at the group and individual level may yield boosts in reading speed for students, without negatively impacting reading comprehension. Full article
