Bridges, owing to their intricacy, represent pivotal yet relatively underexplored assets within the domain of maintenance services in civil engineering. While international evaluation methodologies exist to gauge the overall condition of bridges, they often fall short in establishing interrelationships among individual elements, thereby neglecting insights into the influence exerted by each element’s condition on the bridge’s overall performance. This research introduces an integral fuzzy model evaluation with a preventive approach, designed to assess both the integral condition of a bridge and its constituent elements. Furthermore, the study generates maintenance recommendations, subsequently evaluated by professionals to determine the most suitable course of action based on available resources. To validate the efficacy of the proposed model, a case study involving Bridge 15-016-00.0-0-04.0 PIV, known as “La Cuesta” in Mexico, is presented. The findings indicate that the bridge is in a satisfactory condition and warrants high-priority attention. Bridge analysis is compared with evaluations conducted using the methods of the Secretariat of Infrastructure, Communications, and Transportation (SICT), the American Association of State Highway and Transportation Officials (AASHTO), and the Ministry of Transport and Communications of Peru. The comparative evaluation reveals that our proposed model provides a more detailed representation of deterioration, facilitating more efficient maintenance planning by considering the hierarchical relationships between the bridge’s modules and elements.

Traditional manual crack inspection methods often face limitations in terms of efficiency, safety, and consistency. To overcome these issues, a new approach based on autonomous robotic systems has gained attention, combining robotics, artificial intelligence, and advanced sensing technologies. However, most existing reviews focus on individual components in isolation and fail to present a complete picture of how these systems work together. This study focuses on robotic crack detection and proposes a structured framework that connects three core modules: the physical platform (robots and sensors), the cognitive core (crack detection algorithms), and autonomous action (navigation and planning). We analyze key technologies, their interactions, and the challenges involved in real-world implementation. The aim is to provide a clear roadmap of current progress and future directions, helping researchers and engineers better understand the field and develop smart, deployable systems for infrastructure crack inspection.

Spiritual intelligence (SI) is defined as a unique form of hermeneutic–relational intelligence that enables individuals to integrate cognitive, emotional, and symbolic dimensions to guide their thoughts and actions with reflection, aiming for existential coherence rooted in a transcendent system of meaning. It functions as a metacognitive framework that unites affective, cognitive, and symbolic levels in dialog with a sense of meaning that is considered sacred or transcendent, where “sacred,” in this context, refers inclusively to any symbolic reference or value that a person or culture perceives as inviolable, fundamental, or orienting. It can derive from religious traditions but also from ethical, philosophical, or civil visions. It functions as a horizon of meaning from which to draw coherence and guidance and which orients the understanding of oneself, the world, and action. SI appears as the ability to interpret one’s experiences through the lens of values and principles, maintaining a sense of continuity in meaning even during times of ambiguity, conflict, or discontinuity. It therefore functions as a metacognitive ability that brings together various mental functions into a cohesive view of reality, rooted in a dynamic dialog between the self and a value system seen as sacred.

Flying wing UAVs are widely used in both civil and military areas and they are vulnerable to being affected by multi-source disturbances and actuator faults due to their unique aerodynamic configuration. This paper proposes composite continuous high-order nonsingular terminal sliding mode control controllers for the longitudinal command tracking control of flying wing UAVs. The proposed method guarantees not only the finite-time convergence of command tracking errors, but also the continuity of control actions. Simulation results validate the effectiveness of the proposed method. Full article

This study analyzes how Vietnam’s Ministry of Culture, Sports and Tourism (MoCST) communicates policy implementation in tourism governance through 35 official responses to citizen petitions, using Heidbreder’s Multilevel Policy Implementation Strategies Framework (centralization, agencification, convergence, networking). Content coding, frequency analysis, co-occurrence network, and sentiment analysis reveal a dominant centralization pattern, with MoCST maintaining strong top-down control in decision-making and resource allocation. Convergence reflects increased inter-ministerial coordination, while agencification is limited, and networking with private or civil sectors remains weak. This weak networking limits participatory decision-making and hinders the development of adaptive, community-based tourism initiatives, which are crucial for sustainable tourism governance. Positive sentiment is more associated with centralized and convergent actions, indicating institutional trust. The study extends Heidbreder’s framework to a non-Western, centralized context and calls for stronger local agency roles and inclusive networks to enhance resilience and community ownership in policy implementation.

This article discusses the digital activism model for advocacy of press freedom in Indonesia. This study examined the model and characteristics of digital activism and inhibiting factors in advocacy of press freedom, carried out by civil society organizations, social activists, and media professionals. Using qualitative methods, this paper provides answers to the question of how is the digital activism model aimed at countering threats to press freedom in a post-authoritarian country with a case study of Indonesia? How does digital activism emerge and form cross-sector collaboration? Given the broad scope of digital activism in Indonesia, the researchers chose two cities that represent the national and regional/provincial spectrum, namely Jakarta as the nation’s capital and Yogyakarta as a prominent student city in the country. The current study found a unique digital activism model in Indonesia that is a spectator collaboration: participants and initiators of activism are involved together in clicktivism, metavoicing, and assertion. Social activists and independent media activists develop systematic collective actions in the digital realm, such as online petitions and press releases, republication, and fundraising for the sustainability of the activism itself. This paper also found a gladiatorial model: media managers as victims and activists merged with more organized social movements, signaling that press freedom has become a collective agenda of pro-democracy advocates in Indonesia.

Peatland research has expanded rapidly in the last two decades encompassing a diverse, multi-disciplinary evidence base, as countries seek to manage this resource sustainably along with meeting climate and biodiversity targets. There is growing global interest in the role of peatlands in carbon and water cycles, leading to more interdisciplinary research that applies ecosystem services and other integrative frameworks to generate knowledge and provide guidance for action. These trends have been replicated in Ireland with increasing research in peatland science, applied work on these degraded ecosystems, and a growing interest from civil society, landowners, and communities in the stewardship of this resource. This paper presents evidence-based insights from over two decades of Irish peatland research, with practical lessons for peatland policy and management in other national contexts. Analyses of the evidence from the literature, specialist expertise, and stakeholder knowledge were carried out under ten themes: biodiversity, soil, climate change, water, archaeology and palaeoenvironment, technology and mapping, society and culture, management, growing media and policy and law. The research identified four foundational pillars (accountability, longevity, equity and holistic knowledge) as critical to achieving sustainable peatland management in Ireland, with broader application to other regions. Peatland restoration is widely recognised across research disciplines as a key tool to meet regulatory targets related to climate, biodiversity, and water quality, while also delivering societal benefits. The findings of this research provide accessible, reliable and up-to-date evidence for sustainable peatland management. This study addresses a critical global knowledge gap by developing a novel, interdisciplinary evidence synthesis framework—applied here to Ireland but replicable worldwide—that systematically integrates 20 years of multi-disciplinary peatland research, expert insights, and stakeholder perspectives across ten thematic pillars.

Sustainability is vital to engineering education, requiring future engineers to integrate technological advancements with environmental responsibility. This study explores the relationship between sustainability awareness, pro-environmental behavior, and environmental attitudes among engineering students at Shaqra University, Saudi Arabia. The findings indicate that, while students possess moderate sustainability awareness, their engagement in eco-friendly actions remains limited, despite expressing positive environmental attitudes. Civil Engineering students and those in later academic years show higher awareness, emphasizing the role of departmental focus and academic progression. Correlation analysis reveals a strong link between awareness and behavior (r = 0.628 and p < 0.001), yet multiple regression suggests that neither academic year nor department uniquely predicts sustainable actions once awareness is accounted for. Moreover, while pro-environmental attitudes correlate with behavior in bivariate analysis, their impact diminishes in regression, suggesting that positive environmental values do not necessarily translate into consistent green habits. ANOVA results confirm higher awareness among Civil Engineering students, though differences in sustainable behavior are subtle. These findings highlight the need for curricular reforms that integrate sustainability through experiential learning, bridging the gap between awareness and real-world actions. This study supports Saudi Arabia’s Vision 2030 by promoting environmental awareness and aligning education with labor market needs. It offers tools to help stakeholders and policymakers develop competitive, future-ready generations. Full article

In early 2025, the Santorini–Amorgos area (Aegean Volcanic Arc, Greece) experienced a seismic swarm, with dozens of M ≥ 4.0 earthquakes and a maximum magnitude of M = 5.2. Beyond its seismological interest, the sequence was notable for triggering rare increased preparedness actions by Greek Civil Protection operational structures in anticipation of an imminent destructive earthquake. These actions included (i) risk communication, (ii) the reinforcement of operational structures with additional personnel and equipment on the affected islands, (iii) updates to local emergency plans, (iv) the dissemination of self-protection guidance, (v) the activation of emergency alert systems, and (vi) volunteer mobilization, including first aid and mental health first aid courses. Although it was in line with contingency plans, public participation was limited. Volunteers helped bridge this gap, focusing on vulnerable groups. The implemented actions in Greece are also compared with increased preparedness during the 2024–2025 seismic swarms in Ethiopia, as well as preparedness before the highly anticipated major earthquake in Istanbul (Turkey). In Greece and Turkey, legal and technical frameworks enabled swift institutional responses. In contrast, Ethiopia highlighted the risks of limited preparedness and the need to embed disaster risk reduction in national development strategies. All cases affirm that preparedness, through infrastructure, planning, communication, and community engagement, is vital to reducing earthquake impacts. Full article

This article explores Greco-Roman mythology through the lens of ecocriticism, focusing on how sacred landscapes and natural elements were imagined as animate, divine, and morally instructive forces. In ancient Mediterranean cultures, nature was not merely a passive setting for human action but a dynamic presence—rivers that judged, groves that punished, and mountains that sheltered or revealed. Texts such as Ovid’s Metamorphoses, Virgil’s Georgics, and Homer’s epics present nature as both sacred and sentient, often intervening in human affairs through transformation, vengeance, or protection. Forests, springs, and coastlines functioned as thresholds between human and divine, civilization and wilderness, mortal and eternal. By analyzing these representations, this article reveals a rich tradition in which nature teaches, punishes, guides, and transforms, long before ecological consciousness became a formalized discipline. Drawing connections between classical literary landscapes and contemporary environmental concerns, the article argues that myth can inform today’s ecological imagination, offering an alternative to extractive, anthropocentric paradigms. Recovering the reverence and narrative agency once granted to nature in classical thought may help us rethink our ethical relationship with the environment in the age of climate crisis. Full article

Progressive advancements in the global economy and technology have propelled human civilization forward; however, they have also inflicted significant harm on the global ecological environment. In the present era, electric vehicle (EV) technology is playing a vital role due to its environmentally friendly technological advances. However, widespread adoption of EVs has been hindered by their limited travel range, inadequate charging infrastructure, and high costs. This can be closely observed when we assess the adoption of electric vehicles (EVs) among motorcycle taxi drivers, commonly called ‘pilots,’ in Goa, India. Motorcycle taxis are crucial in Goa’s transportation network, providing affordable, efficient, and door-to-door services, especially in regions with limited public transport options. However, the rising costs of petrol and vehicle maintenance have adversely affected the income of these pilots, prompting concerns about their willingness to adopt EVs. This study aims to analyze the factors prompting the behavioral intention to adopt EVs by motorcycle taxi pilots in Goa, India, focusing on six key determinants: charging infrastructure, effort expectancy, performance expectancy, price value, social influence, and satisfaction with incentive policies. A quantitative approach was employed, utilizing stratified proportionate random sampling techniques to collect data from 242 motorcycle taxi pilots registered with the Goa State Government Transport Department. It was analyzed using partial least squares-structural equation modeling (PLS-SEM) through Smart-PLS 4.0 software. The research highlights that performance expectancy and price value are the potential motivators for the adoption of electric vehicles. These findings suggest that pilots are more likely to embrace EVs when they perceive tangible benefits in performance and find the cost reasonable in relation to the value offered. The results offer actionable insights for policymakers, manufacturers, and other stakeholders. These insights can guide strategic decisions and policy frameworks aimed at fostering a sustainable and user-centric transportation ecosystem. Full article

This study investigated the technical feasibility and antimicrobial potential of incorporating ornamental rock, limestone, and ginger waste into coating mortars with the aim of developing an innovative and sustainable solution for civil construction. This study evaluated the synergistic action of these materials on the microbiological and mechanical resistance of mortar, contributing to the greater durability and efficiency of the coatings. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD) analyses were performed to characterize the morphology, chemical composition, and crystalline structure of the added materials, confirming their suitability for the cement matrix. Tests in the fresh state evaluated parameters such as density, consistency index, and entrained air content, demonstrating the viability of the formulations, whereas flexural and compressive strength tests indicated significant improvements in the mechanical performance of the modified mortar. Microbiological tests demonstrated a significant reduction in microbial colonization, indicating the action of ginger’s bioactive compounds, such as gingerol and shogaol, which have antimicrobial properties and are effective in inhibiting the growth of pathogenic microorganisms, as confirmed by the reduction in the bacterial colony count from 4 × 10² to 1 × 10² CFU mL⁻¹. Comparisons with conventional compositions indicate that the proposed approach outperformed traditional formulations in terms of both mechanical resistance and microbiological control. Thus, the results validate this research as a promising strategy for improving the durability and performance of coating mortars, reducing maintenance costs, and promoting the sustainable use of alternative materials in civil construction.

Background: Landscape approaches are recognized for their holistic view on development and conservation. However, they encounter sustainability and localization challenges due to short-term funding constraints and dependence on external experts. In this paper, we examine commoning as a means of land tenure interventions that enable mixed land use and community stewardship. Methods: Based on desk research and 20 interviews, an institutional analysis was performed on two landscape management cases to shed light on commoning processes and land tenure changes, as well as their impact on land use and community stewardship. Results: In the first case, a collaborative governance model was developed through policy interventions, which provided not only institutional frameworks but also financial resources to incentivize landowners to cooperate with nature conservation groups and share management rights over their land. In the second case, a community land trust model was used by self-organized civil society actors to develop ecovillage practices and ensure the balance of conservation and agricultural uses. In both cases, we found that land tenure innovations in terms of boundary rules, choice rules, aggregation rules, as well as rules for higher-level action situations, were key to enabling land rights sharing, mixed land use, and different levels of stewardship depending on the preferences and capacity of stakeholders. Conclusions: Commoning could address the sustainability and localization challenges faced by landscape approaches to mixed land use and long-term adaptive management. Full article

The sustainable development of the coastal watersheds can contribute to facing climate change. This research aimed to identify the climate change adaptation measures contributing to the sustainable development: environmental, social, and economic, applied to a local project that promoted an integrated environmental management of coastal watersheds, “The Coastal Watershed Conservation Project in the Context of Climate Change (C6)”. The study used a quantitative evaluation framework and analysis of variance that considered the Sustainable Development Goals (SDGs) of the Agenda 2030. The data was collected from project reports and key actors of the 29 interventions executed by 24 local civil society organizations in the Mexican Tabasco and Veracruz communities in the coastal Gulf of Mexico. The results indicate that the adaptation actions implemented through the C6 project contributed to sustainable development with the highest contribution in the social aspect (41%), followed by environmental (27%), economic (16%), peace (10%), and partnership (7%). Therefore, it can be concluded that local civil society organizations created strategies according to the local needs to face climate change and, at the same time, to improve sustainable development in their communities.

In many European cities, old urban centres, particularly historical centres, reveal significant limitations to the intervention of civil protection agents—namely, firefighters—in terms of their mobility and action in emergencies, thus conditioning their action. This article analyses the case of a Portuguese city (the city of Ílhavo), proposing possible solutions applicable to territories with these specificities. This study was developed with the support of a literature review and field work that accompanied the actions of the local fire department. The proposals include new technical solutions (such as underground dry pipeworks), measures regarding traffic restrictions, the adequacy of signage, and recommendations for training the population living in these areas to intervene in fire situations. This study was developed through monitoring several interventions by the local fire department in real emergencies, allowing for the identification of some existing limitations in its activity resulting from the specific characteristics of the old urban centre. Measures already adopted in other Portuguese cities to improve mobility and reduce the negative impact on firefighters’ work in historical centres are also mentioned. It is also recommended that all civil protection agents be closely involved in planning and designing these urban rehabilitation interventions when carrying them out in these areas. Full article
