Titanium implants are widely used in medicine because of their favorable mechanical properties and biocompatibility; however, the rapidly forming titanium oxide coatings do not provide an ideal bioactive surface to stimulate osseointegration. This study aims to enhance titanium implant osseointegration through anodization processes designed to incorporate elements and compounds present within human bone into the surface oxides. Commercially pure titanium grade 4 (CPTi) discs were anodized in either oxalic, malic, or ascorbic acid-based electrolytes. Each resulting oxide exhibited complex surface topographies. EDS analyses revealed that Ca, P, and Mg bone chemistry dopant elements were incorporated into each of the oxide coatings. X-ray diffraction analyses revealed combinations of anatase and calcium titanate compounds present in each oxide. Additionally, two of the anodized oxides showed calcium oxide formation, and one oxide also revealed tricalcium phosphate (α-TCP) and hydroxyapatite (HA) formation. Subsequent FTIR spectroscopy analyses revealed carbonate substitution peaks to be present in two of the oxides. This finding indicated that the TCP and HA compounds shown in the XRD analyses of one oxide represented the formation of bone-like carbonated calcium phosphate compounds. A 21-day cell culture study showed favorable cell culture responses for each of the organic-acid-based anodized oxides. Moreover, two of the oxides showed good cytocompatibility and early osteogenic differentiation compared to non-anodized titanium controls. Thus, the organic acid anodization processes developed in this study show promise to enhance future titanium implant clinical outcomes. Full article

The cult of Queen Saint Elizabeth constitutes one of the most persistent manifestations of popular religiosity in central Portugal, especially in Coimbra. Following her death, popular veneration of this saint rapidly consolidated, later legitimized by her beatification in 1516 and canonization in 1625. This article aims to understand how Elizabethan devotion currently constructs an identity in Coimbra, Portugal. To characterize the pilgrimage and expressions of faith, I observe the biennial festivities, the processional routes, sacrifices, adherence, and generational beliefs in this feminine cult, relating them to the pursuit of health. The article studies the main institutions that regulate devotion in modern times (notably the Confraternity of Queen Saint Elizabeth) and explores some processes of its patrimonialization and touristification. Finally, I also analyze the performativity of rituals and the identity of pilgrims, highlighting how expressions of faith also constitute social, cultural and economic practices. The study is based on ethnographic fieldwork, interviews and documentary analysis. The ethnography (still ongoing) on this very Portuguese pilgrimage already reveals points of differentiation and of commonality with other more famous pilgrimages, such as Fátima and Lourdes, while remaining a significant and unique part of the character of popular religiosity and the local identity of Coimbra.

Contemporary cultural tourism faces a critical digital authenticity paradox where social media engagement necessitates platform integration, yet algorithms prioritize engagement-driven content over culturally accurate heritage representations. This systematic review develops an initial framework addressing authenticity preservation challenges through systematic analysis of platform-mediated heritage representation. Following PRISMA guidelines, researchers searched Scopus and ScienceDirect databases for peer-reviewed articles published 2020–2025 using search terms: “Cultural Tourism” AND “Heritage Tourism” AND “Photograph” AND “Social media” AND “Authenticity.” Inclusion criteria encompassed English-language journal articles and conference papers in social sciences, business, management, and humanities. VOSviewer software facilitated bibliometric analysis through keyword co-occurrence mapping with minimum three-occurrence threshold. From 68 articles, analysis revealed five thematic clusters: Ecosystem Tourism, Social Media and Technology, Tourism Management, Authenticity, and Photography & Storytelling, informing an integrated Input-Process-Integration-Output framework. Input encompasses cultural contexts and authenticity evaluation criteria; Process integrates social media dynamics with tourism management strategies; Integration synthesizes authentic contexts through platform-adapted digital storytelling; Output addresses platform-mediated tourist experiences. The framework establishes systematic relationships between heritage preservation and digital platform mechanisms, providing methodological innovation while addressing algorithmic optimization conflicts with heritage preservation, offering practical guidance for tourism organizations navigating Instagram, TikTok, Facebook, and emerging platforms while preserving authentic cultural representation.

This paper presents a thematic literature review of 35 studies to examine key developmental factors influencing expatriate adaptation, including language, identity integration, cultural intelligence, and spousal/family relations, impacting expatriate adaptation and acclimation to the host country. For the purposes of this review, the term “expatriate” refers to individuals who temporarily relocate abroad for education or professional assignments (self-initiated and assigned), often accompanied by spouses or family members. “Adaptation” is defined as the multidimensional process of adjustment to new academic, workplace, and social environments, encompassing both practical adjustment (e.g., communication, work/study tasks) and psychological well-being. This review uses two bibliometric reviews to set the foundation for exploring the impacts of language, identity integration, cultural intelligence, and family, highlighting that interactions with locals foster language development, identity integration, and cultural intelligence, which collectively enhances expatriates’ perceived sense of comfort and belonging. Spousal and family dynamics appear to be particularly influential, with the potential to either support or hinder successful adaptation. Although prior literature often focuses on these factors in isolation, this paper synthesizes them to provide a more holistic understanding of expatriate acclimation. It emphasizes the need for future research to explore the interrelated nature of these variables and their combined impact on expatriate well-being. Full article

This study examines the adoption and implementation of the Zero Trust (ZT) cybersecurity paradigm using the Technology–Organization–Environment (TOE) framework. While ZT is gaining traction as a security model, many organizations struggle to align strategic intent with effective implementation. We adopted a sequential mixed-methods design combining 27 semi-structured interviews with cybersecurity professionals and a survey of 267 experts across industries. The qualitative phase used an inductive approach to identify organizational challenges, whereas the quantitative phase employed Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the hypothesized relationships. Results show that information security culture and investment significantly influence both strategic alignment and the technical implementation of ZT. Implementation acted as an intermediary mechanism through which these organizational factors affected governance and compliance outcomes. Strategic commitment alone was insufficient to drive effective implementation without strong cultural support. Qualitative insights underscored the importance of leadership engagement, cross-functional collaboration, and legacy infrastructure readiness in shaping outcomes. The findings emphasize the need for cultural alignment, targeted investments, and process maturity to ensure successful ZT adoption. Organizations can leverage these insights to prioritize resources, strengthen governance, and reduce implementation friction. This research is among the first to empirically investigate ZT implementation through the TOE lens. It contributes to cybersecurity management literature by integrating strategic, cultural, and operational dimensions of ZT adoption and offers practical guidance for decision-makers seeking to institutionalize Zero Trust principles.

Digital storytelling has emerged as an innovative approach that integrates technology with education, demonstrating growing research and practical value in cultural heritage preservation. This study focuses on China’s industrial heritage and conducts empirical research with primary school students (Years 1–6) to examine how digital storytelling enhances engagement in industrial heritage education in particular, but also how industrial heritage reflects and links to wider cultural and historical issues. The research analyzes six key educational dimensions: learning interest, functional preferences, content comprehension, supervisory expectations, creative expression, and willingness to participate. Hypothesis testing revealed significant positive correlations among these dimensions (p < 0.05), and the overall regression model explained 51% of the variance in students’ willingness to participate (R² = 0.51). Grade-level analysis further demonstrated distinct developmental patterns: younger students preferred gamified interactions with parental supervision, middle-grade students gradually shifted toward personalized learning approaches, and senior students focused more on value-driven and inquiry-based content. A temporary decline in interest and willingness around Year 5 highlighted a key transitional period requiring targeted scaffolding for abstract and creative learning tasks. Based on these insights, the study innovatively proposes a “Sapling Growth” educational framework that systematically combines digital storytelling technology with children’s cognitive development patterns. This progressive three-stage instructional design achieves dynamic alignment between teaching content and students’ cognitive abilities. The framework integrates cultural depth with interactive features, establishing a theoretical pathway to enhance learning processes, strengthen cultural identity, and promote sustainable industrial heritage preservation, while providing a foundation for interdisciplinary integration across educational technology, cultural heritage conservation, and child development fields.

The global challenge of food insecurity requires innovative approaches for sustainable food production and waste valorization. This study investigates the valorization of oat hulls, an abundant lignocellulosic by-product from oat manufacturing, by solid-state fermentation using edible filamentous fungi. Oat hulls sourced from oatmeal industrial side-streams were used as the sole substrate in co-cultures of Neurospora intermedia and Rhizopus oryzae. The fermentation process was optimized and upscaled, with fungal growth monitored via CO₂ efflux and modeled to assess substrate utilization. Comprehensive analyses revealed a significant increase in protein concentration (p < 0.05) in the fermented oat hulls compared to the non-fermented controls. The resulting product was successfully incorporated into granola bars, which underwent sensory evaluation and received positive feedback, demonstrating its potential as a value-added food ingredient. These findings highlight the feasibility of using edible fungi to upcycle cereal processing by-products into nutritionally enhanced alternative protein sources, supporting both food system sustainability and circular bioeconomy objectives.

The paper presents a theoretical reflection on accessibility, developed through dialogue between an architect and a philosopher. It explores the cultural horizon of a transdisciplinary discipline whose conceptual boundaries remain fluid and examines the role accessibility can play in creating a freer and more inclusive society. At the core of the paper lies the concept of accessibility as a Cultural Generative Ecosystem, a dynamic and evolving construct through which accessibility operates as a transformative force. This ecosystem is embedded within a conceptual framework structured around specific Fields of Inquiry (Relational, Spatial, Institutional) and Domains (Person, Society, Environment). In this perspective, accessibility is presented as a complex process rooted in humanistic values and grounded in care ethics, phenomenological experience, and human rights. The paper highlights the potential of accessibility to counter diversity-related discrimination, promote empowerment, and guide the transformation of human habitats in line with people’s needs and expectations. At the same time, it acknowledges the objective and cultural challenges involved in cultivating an accessibility-oriented mindset. Following a comprehensive theoretical and methodological groundwork that lays the foundation for a broader conceptual reframing of accessibility, the paper identifies six conceptual determinants that define its complexity in the built environment, particularly in relation to disability and the relational nature of public space. These determinants—polysemous, contextual, multi-scalar and relational, corporeal and spatial-temporal, multi-criteria, and multi-component—are examined in relation to the four interwoven dimensions that structure the Cultural Generative Ecosystem of accessibility: technical, social, organizational, and generative. Together, they offer a framework for rethinking inclusive design as a situated, relational, and ethically grounded practice. Full article

Contemporary architecture is undergoing a transformation from the modernist techno-functional paradigm towards practices that integrate technology with humanistic, cultural, and environmental values. Biophilia—understood as the innate human need for contact with nature—is becoming an important design category that supports health, well-being, and ecological awareness, yet it can also convey additional narratives. In this context, immersion plays a significant role: it is a process of deep engagement of the user with space, involving the senses, emotions, and imagination, while simultaneously fostering relationships between humans and their surroundings. The concept of immersiveness, originating in art theory and digital media studies, is now applied in architecture as a tool for creating spatial narratives and cultural experiences. Biophilic architecture employs immersive strategies to transform buildings into environments that support sensory, behavioural, and social practices. This article analyses selected examples of such projects (including the Rooftop Garden—Warsaw University Library, Musée du quai Branly, and apartment buildings Bosco Verticale) and proposes a Multi-criteria Method for Assessing Architectural Immersiveness (MMAAI). The findings indicate that the integration of nature, technology, and spatial narrative enables architecture to act as a mediator between humans and the environment, generating new qualities of spatial experience in the Anthropocene epoch.

In the context of museums’ transformation into active social agents, the Entre Luces (Between Lights) project, developed at the Pablo Gargallo Museum in Zaragoza, serves as a compelling example of accessibility understood as a shared cultural responsibility. Implemented within a listed heritage building, where structural modifications were not possible, the project deliberately shifted the focus from architectural accessibility to communicative, cognitive, and sensory dimensions, placing the quality of the cultural experience at the centre. The study employed a qualitative case study design based on document analysis, participant observation, and semi-structured interviews with museum staff, educators, and members of disability organisations. Through a participatory and iterative co-design process, curators, educators, vocational students, and disability organisations collaborated to develop inclusive solutions. People with disabilities were not regarded as passive users but as co-authors of the process: they contributed to the creation of tactile replicas, audio descriptions, sign language resources, braille, pictograms, and motion-activated audio systems. The project generated three main outcomes. It expanded cultural participation among people with diverse disabilities, enriched the sensory and emotional experience of all visitors, and initiated an institutional transformation that reshaped staff training, interpretive approaches, and the museum’s mission towards inclusivity. Entre Luces demonstrates that even small and medium-sized museums can overcome heritage constraints and promote cultural equity and social innovation through inclusive and sensory-based approaches.

Academic failure and social inequalities are becoming more prevalent in schools. While knowledge has evolved and society has undergone significant transformation, schools have largely remained structured around a uniform model applied indiscriminately to all. In Portugal, efforts were made to initiate change through the conceptualisation and implementation of innovation plans to alter the prevailing grammar of schooling, prompting an inquiry into whether these initiatives yielded the intended outcomes. To this end, a case study was conducted in two such schools, aiming to capture the perspectives, ideas, and perceptions of various stakeholders: students and teachers through questionnaires, coordinating teachers via narrative accounts, and school leaders through semi-structured interviews. The findings reveal that the contexts of implementation, the scale of the initiative, and the number of schools involved significantly influence both practices and leadership outcomes. Nonetheless, despite these constraints, the innovation plans facilitated the emergence of more collaborative dynamics and the creation of more meaningful learning environments, wherein students assumed a more active role in their educational processes. The results further indicate that these innovation plans encountered obstacles rooted in entrenched professional and organisational cultures, which hindered profound changes in the structuring of teaching and learning practices.

In recent years, the development of stretchable electronic devices with mechanical properties similar to those of human tissues has attracted increasing research interest in biomedical engineering, wearables, and other fields. These devices have demonstrated, and some other researchers have already shown, promising advancements towards applications that span from measurements of the disruption of model barrier tissues to wearable or implantable devices, soft robotics, and the development of flexible and stretchable batteries. For example, models of barrier tissues, consisting of two compartments separated by a porous membrane, have been used to measure their integrity as well as to investigate the passage of drugs, toxins, and cancer cells through these tissues. Some of these models include an elastomeric membrane which can be stretched to model processes such as breathing and gut peristalsis, while others include electrodes for real-time measurement of barrier tissue integrity. However, to date, microelectrodes have not been fabricated directly on a porous elastomeric membrane. Here, we present lithographically patterned gold electrodes on porous PDMS membranes that enable electronic sensing capabilities in addition to mechanical manipulation. These membranes are incorporated into vacuum-actuated devices which impart cyclic mechanical strain, and their suitability for electrical impedance measurements, even after 1000 stretching cycles under fluids similar to cell culture media, is demonstrated. In the future, we expect to use these electrodes to measure the disruption in model cell barriers as well as to dielectrophoretically trap cells in a region of interest for more rapid assembly of a model tissue. Other areas like wearables, robotics, and power sources will greatly benefit from the further development of this technology. Full article

The presence of substantial amounts of heavy metals in the environment can result in various significant ecological issues and human health risks. Currently, bioremediation employing microorganisms is garnering significant interest due to its effectiveness. The present investigation aimed to isolate actinobacterial strains from an Italian mine and to characterise them for heavy metals resistance and plant growth-promoting characteristics. The different samples were processed for DNA extraction and 16S rRNA gene metabarcoding to investigate the bacteria and archaea communities. Cultivable microbiota were isolated and evaluated for heavy metals tolerance and different PGP traits. The most pertinent strains were tested for compatibility, merged into a consortium, and tested on Lemna minor L. Metabarcoding analysis revealed that amplicon sequence variants (ASVs) at the phylum level were mostly assigned to proteobacteria and bacteroidota. Uncultured and unknown taxa were the most prevalent in the samples at the genus level. A total of ten strains were obtained from the culture-dependent approach exhibiting interesting heavy metals tolerance and plant growth-promoting traits. The best strains (MTW 1 and MTW 5) were selected and further characterised by 16S barcoding. These strains were identified as Streptomyces atratus (99.57% identity). An in planta experiment showed that the metal-tolerant consortium MTW 1-5 improved plant physiology by significantly optimising plant growth and tolerance to heavy metals. The experiment conducted provided evidence for the possibility of using actinobacteria as bioaugmentation agents to improve the phytoextraction abilities of L. minor. Full article

Asian film displays a range of perspectives on ritual and political issues of contest and contestation. Using modified snowball and purposive sampling, film and some television is selected for the presence of ritual politics, political theater, and important Asian cultural, religious, and/or political perspectives. Some perspectives identified are localized, regional, or may have resonance (not representativeness) in many parts of Asia from Kazakhstan, Nepal, India, and eastward; a few preliminary observations are offered in this regard. The current work is an effort in cultural de-coding, and perhaps cultural translation, using qualitative content analysis, coding, and comparative historical–institutional analysis at the intersection of culture and politics. The argument is methodological (qualitative), encouraging political scientists and others with interests in cross-national, comparative, and international religion and politics to delve into thick description using international, foreign-language film as a (relatively unmined) source of cultural data and cultural, values-oriented, and political messaging. Ritual politics is treated herein as formal or informal ritual involving symbolic activities occurring in a religious, semi-religious, or secular context that is used for political purposes, in a political context, or to effect a political message. The current work is preliminary and is part of a larger project; it provides a preliminary spreadsheet of 24 out of over 100 canvassed films seeking to combine conceptual variables with binary coding.

Apple represents one of the most economically significant fruit crops worldwide, and the performance of its scion is largely determined by the physiological and genetic characteristics of the rootstock. Despite their superior ecological adaptability and growth-controlling attributes, many dwarfing apple rootstocks exhibit inherently poor rooting competence, which poses a critical limitation to their large-scale clonal propagation and commercial utilization. Adventitious root (AR) formation is a pivotal yet highly intricate developmental process that governs the success of asexual propagation. It is orchestrated by a complex network of hormonal signaling, transcriptional regulation, metabolic reprogramming, and environmental cues. Over the past decade, remarkable advances have elucidated the physiological, biochemical, and molecular frameworks underpinning AR formation in apple rootstocks. This review provides an integrative synthesis of current progress in vegetative propagation techniques—including cutting, layering, and tissue culture—and systematically dissects the endogenous and exogenous factors influencing AR development. Particular emphasis is placed on the regulatory interplay among phytohormones, carbohydrate and nitrogen metabolism, phenolic compounds, transcription factors (such as WUSCHEL-RELATED HOMEOBOX (WOX), LATERAL ORGAN BOUNDARIES DOMAIN (LBD), and RESPONSE FACTOR (ARF families), and epigenetic modulators that collectively coordinate root induction and emergence. Furthermore, emerging insights into multi-omics integration and genotype-specific molecular regulation are discussed as strategic pathways toward enhancing propagation efficiency. Collectively, this review establishes a comprehensive theoretical framework for optimizing the asexual propagation of apple rootstocks and provides critical molecular guidance for breeding novel, easy-to-root genotypes that can drive the sustainable intensification of global apple production.
