During the modern period, convents and monasteries served as fertile grounds for female writing. Religious constitutions mandated literacy for certain positions, leading to extensive administrative documents, autobiographies, and exemplary life accounts. However, female writing within cloister extended beyond administrative and religious matters, encompassing diverse and often rebellious letters. This study aims to examine 18th-century female epistolography within the Portuguese Empire, focusing on letters written by nuns at the Convent of Santa Monica in Goa. The research centers on a significant crisis between 1721 and 1738, during which the Augustinian nuns were in conflict with the Archbishop of Goa, D. Fr. Inácio de Santa Teresa. This dispute led to a division within the religious community and generated a substantial body of documents, many written and/or signed by the nuns themselves. The objective is to analyze these letters to understand the discursive positions and forms of self-representation adopted by the religious senders, examining how they dialogued or conflicted with the societal constraints of the period.

Research in the analytical and preparative fields of separation science has a long-standing tradition in the Czech Republic and former Czechoslovakia. Czech and Slovak scientists recognized the advantages of the two most widely used separation techniques, i.e., chromatography and electrophoresis, soon after their discovery and broader adoption. Their contributions to the development of the fundamentals and applications of chromatography and electrophoresis are demonstrated not only by numerous publications in renowned scientific journals and books, but also by several breakthrough innovations that led to patents and sometimes also to successful commercialization. The contributions of the earlier most prominent Czech scientists to the development of separation sciences have already been summarized in the literature. In the following lines, we instead aim to highlight less well-known, yet important, contributions within the Czech chromatographic and electrophoretic community. Moreover, recent developments since the last comprehensive reviews are covered in greater depth. Full article

Background/Objectives: Chronic diseases account for 74% of global deaths, with multimorbidity (existence of more than one chronic condition) increasing disability risk and treatment burden, leading to poor adherence, disease progression, and reduced quality of life. Nursing-led proactive care models that focus on patient engagement, education, and self-care can help mitigate these challenges. The study aims to evaluate the effectiveness of a nurse-led proactive health intervention in improving care for individuals with chronic diseases in general practice. Methods: A quasi-experimental pre–post study will be conducted in a Community Health Home in Northern Italy. Family and community nurses will deliver the intervention, which includes assessments, educational sessions, and follow-ups for patients aged 65+ with at least one chronic condition. Recruitment will occur over three months. Results: Primary outcomes include emergency department visits and hospitalizations, while secondary outcomes focus on medication adherence, self-care, and service utilization. Data will be collected at 6 and 12 months, and statistical analysis will use descriptive methods and generalized estimating equations (GEEs). Conclusions: This study will improve the understanding of the value of nurse-led proactive intervention, filling the gap in the literature by testing evidence-based approaches on a realistic frail population. Moreover, delivering a complex but structured intervention will provide evidence for future interventions to reduce treatment burden and improve health outcomes. Full article

Rising cancer incidence and survival rates have led to an unprecedented demand for psychosocial care. Yet, limited financial and practical resources present a barrier to the provision of evidence-based care. Clinical practice guidelines (CPGs) are well-positioned to enhance the quality and efficiency of psychosocial oncology care; however, little is known about their use and perceptions in the field. The present study explored the use and perceptions of CPGs among 172 Canadian psychosocial oncology clinicians via a cross-sectional, online survey. Findings revealed substantial variation in awareness, with over 20% of participants reporting no familiarity with CPGs, and low to moderate use of CPGs (M = 2.97, SD = 2.96) among users. Key barriers included a lack of formal training, limited applicability to local contexts, and systemic constraints such as high workloads. Conversely, participants highly endorsed facilitators, including accessible training programs, relevant tools/interventions, and greater institutional and community engagement. Clinician perspectives are paramount to the dissemination and implementation of psychosocial oncology CPGs. Our findings suggest that successful implementation requires broader accessibility, widespread adaptation, and greater community engagement. By addressing these systemic constraints, CPGs may be better positioned to bridge the gap between evidence and real-world service provision. Full article

Background/Objectives: Health literacy (HL) is recognized as an important social determinant of health. It supports healthy behaviors and effective health management throughout one’s life. For children and adolescents, developing HL influences their well-being, development, and ability to make informed health decisions. Nurses are strategically positioned to promote HL from an early age. To our knowledge, no prior synthesis has specifically examined nurse-led HL interventions targeting pediatric populations, highlighting the originality and relevance of this scoping review. The purpose of this review was to map and characterize nursing interventions aimed at improving HL outcomes in children and adolescents. Methods: A scoping review was conducted according to the Joanna Briggs Institute methodology, using a three-step search strategy, and reported in accordance with the PRISMA-ScR guidelines. Searches were conducted in MEDLINE, CINAHL, Scopus, Web of Science, and ProQuest with no date restriction, including studies published in Portuguese, English, or Spanish. Studies involving children and adolescents (ages 0–18) in any healthcare or community setting were eligible. Data on intervention characteristics and HL outcomes were extracted and analyzed descriptively, and no critical appraisal of the included sources was conducted. Results: A total of 44 studies were included. Interventions were predominantly school-based and focused on adolescents (n = 26), with a clear gap in early childhood (n = 2). Studies of early childhood primarily used storytelling and reading activities, whereas interventions targeting older children and adolescents more often employed participatory educational strategies, group-based approaches and digital platforms. The most frequently addressed topics were chronic disease management (n = 12), mental health (n = 7), and nutrition (n = 5). HL domains mainly focused on healthcare and health promotion, with fewer studies addressing disease prevention. Most interventions were conducted in school settings (n = 24), highlighting this context over those in primary care, community, and hospital settings. Conclusions: The results revealed nursing interventions used to promote HL, particularly in the management of chronic diseases, mental health and nutrition. However, the existing body of research is still limited. Key gaps include the absence of standardized measurement tools and the scarcity of longitudinal studies evaluating long-term outcomes. These limitations constrain the comparability and generalizability of findings, highlighting the necessity of more rigorous, methodologically robust research to support evidence-based practices. This scoping review comprehensively maps nurse-led interventions that promote HL among children and adolescents, identifying key priorities to guide future research in this area. Full article

The construction industry is characterised by high raw materials consumption and large waste generation. Upcycling waste construction materials offers an opportunity to reduce embodied carbon emissions while creating community assets. This paper examines how integrated design supports the effective reuse of waste materials from a modular building factory through the design of a community garden pavilion. Using Whole Lifecycle Assessment, the carbon impacts of three scenarios were evaluated. Case 1, the baseline scenario, represented the traditional temporary accommodation system using new materials with a hybrid steel–timber structure. Case 2 adopts new materials for the timber frame structure, combined with reused wooden pallets for the envelope. Case 3 represents an upcycling scenario where structural and envelope materials are reused from the modular building factory’s waste streams. Results show that the whole-life carbon emissions were 15,892.32 kgCO₂e for Case 1, 4293.25 kgCO₂e for Case 2, and 3044.99 kgCO₂e for Case 3, representing reductions of 73% and 81%, respectively, compared with the baseline. The findings demonstrate that integrated design and industrial material reuse can significantly reduce embodied carbon across a building’s life cycle. Recommendations for applying modular factory waste in community-led urban projects are provided. Full article

Introduction: Squalius palaciosi (Doadrio, 1980; Leuciscidae) is a highly threatened freshwater fish species with an extremely restricted distribution, currently confined to a few tributaries on the right bank of the Guadalquivir River basin. During the 1980s, its populations were abundant and constituted a dominant component of local fish communities. However, multiple threats led to a drastic population decline, bringing the species to the brink of extinction. From an evolutionary perspective, S. palaciosi is particularly remarkable due to its polyploid condition and its potential involvement in hybridogenetic complexes, a rare phenomenon in the Iberian Peninsula. Hybridogenetic systems are well documented in its congeners Squalius alburnoides, widely distributed across Iberian river basins, and Squalius sp., restricted to the Guadiana basin. In these systems, the maternal lineage is shared (Squalius pyrenaicus), whereas the paternal lineage varies and remains unknown in S. palaciosi. Objective: This study aims to generate the first genomic data for S. palaciosi and to elucidate its evolutionary origin, as well as its mitochondrial and nuclear phylogenetic relationships within hybridogenetic complexes. Methodology: Genomic DNA was extracted from skeletal remains of preserved specimens housed in the fish collection of the National Museum of Natural Sciences (MNCN-CSIC) and subjected to Illumina short-read sequencing. After quality filtering, potential contaminant reads were removed. The complete mitochondrial genome and several nuclear gene fragments were assembled. Mitochondrial phylogenetic analyses were conducted using publicly available whole-genome sequencing data from Iberian freshwater fish species. Nuclear gene fragments were taxonomically assigned using BLAST analyses. Results: Phylogenetic analyses revealed that S. palaciosi is closely related at the mitochondrial level to S. alburnoides and S. tartessicus, with strong statistical support. BLAST-based taxonomic assignments of nuclear markers suggest the involvement of multiple Iberian freshwater fish species in the hybridogenetic origin of S. palaciosi. Conclusions: Our results provide novel insights into the evolutionary history of S. palaciosi and support a complex hybridogenetic origin involving multiple parental lineages. This study contributes to a better understanding of hybridogenetic speciation in freshwater fishes, a rare but evolutionarily significant process. Full article

Underwater communication is essential for marine research, yet saline environments pose significant challenges as electromagnetic waves suffer from severe attenuation and optical systems face scattering. Consequently, acoustic transmission remains the most practical method for medium- to long-range communication. This study investigates the impact of salinity, transmission frequency, and propagation distance on signal integrity, specifically focusing on the feasibility of using a square-wave carrier with On-Off Keying (OOK) modulation as a simpler, low-cost alternative to traditional sinusoidal frequency-shift keying (FSK). Experiments were conducted in a custom glass tank and analyzed via MATLAB. The results reveal that increased salinity and higher frequencies led to greater signal distortion and attenuation, which complicates reliable binary recovery. However, despite these environmental hurdles, the study demonstrates that square-wave OOK allows for successful binary data recovery over short distances. The findings suggest that simplified modulation schemes could potentially be used for short-range underwater communication in controlled environments, particularly where minimizing system complexity is of concern. Ultimately, the work provides valuable insights into how environmental factors influence acoustic signal integrity, offering a preliminary basis for future development of accessible and efficient underwater communication platforms targeted to shallow water communication.

Cultural heritage is a critical pillar of identity, social cohesion and continuity within ethnocultural communities. However, the preservation of cultural heritage across Southern Africa is largely constrained by fragmented colonial policy implementation, and limited community engagement. This study critically examines the application of the Evidence-Based Policy and Practice (EBPP) model as a decolonizing framework for sustainable management of cultural heritage. The study conducts a structured scoping review of literature to explore the integration of EBPP with the principles of Collective Benefit, Authority to Control, Responsibility, Ethics (CARE), and the principles of Findable, Accessible, Interoperable, Reusable (FAIR) to support inclusive and ethical governance. The findings of the study reveal that sustainable management of cultural heritage is dependent upon community-led governance, alignment between research, policy, and practice, and strengthening of intellectual property protections. The study identifies persistent gaps in the operationalization of indigenous knowledge policies and highlighted the need for participatory approaches to ensure the long-term sustainability of cultural heritage. The study argues that the integration of EBPP, alongside the principles of CARE and FAIR, significantly enhances accountability, fosters data sovereignty, and supports the decolonization of knowledge systems. Thus, the study makes a significant contribution to the growing global discourse on sustainable development by positioning cultural heritage as a dynamic resource for social transformation.

Herein, p-NbSe₂ thin films were deposited onto n-Si substrates to fabricate an n-Si/p-NbSe₂ (SNS) heterojunction for visible light communication (VLC) applications. Structural analysis revealed that the NbSe₂ films possess a trigonal phase and are composed of slightly elongated and irregularly shaped grains with an average size of 0.131 μm. Electrical characterization showed that the SNS heterojunction exhibits pronounced rectifying behavior, with a bias-dependent asymmetry factor reaching 6.6 × ${10}^3$. The photodetection performance of the device was evaluated under illumination from white, blue, red, tungsten, and infrared LEDs. The device exhibited excellent photodetection characteristics across the visible region, achieving a maximum responsivity of 3.79/3.68 AW⁻¹, external quantum efficiency of 1160/809%, noise equivalent power of 4.43 × 10⁻¹⁴ /4.57 × 10⁻¹⁴ WHz^−1/2, and specific detectivity of 3.91 × 10¹²/3.79 × 10¹² Jones under blue/white light illumination, confirming its practical relevance for VLC systems. In addition, frequency-dependent photocurrent measurements under modulated blue and white LED illumination revealed −3 dB bandwidths of approximately 775 Hz and 716 Hz, respectively, supporting the potential of the n-Si/p-NbSe₂ photodiode for low-frequency VLC-related visible-light detection. Compared with previously reported photodiodes used in VLC and IR technologies, the present device demonstrated superior responsivity and EQE%, together with competitive NEP and detectivity. The enhanced performance is attributed to efficient photocarrier generation and collection across the Si/NbSe2 heterojunction. These results confirm that the fabricated SNS photodiode is a promising candidate for high-sensitivity and efficient visible light communication applications. Full article

In Optical Camera Communication (OCC), precise localization of LED arrays under complex tilt conditions is a core challenge for reliable decoding. This paper proposes an OCC reception scheme for RGB-LED arrays that integrates YOLO-OBB rotated object detection with two-stage geometric correction. The system first employs a YOLOv8n-OBB model to extract a quadrilateral region of interest that tightly encloses the LED array boundary. This effectively suppresses background interference caused by superimposed perspective tilt and in-plane rotation. A coarse-to-fine two-stage correction framework is then applied. The first stage rapidly eliminates the dominant perspective distortion based on the detected bounding-box corners. The second stage performs a refined correction using the actual LED center positions. Two homography matrices are cascaded into a combined transformation, achieving two-stage correction accuracy through a single coordinate mapping. In the corrected image, K-Means clustering constructs a 16 × 16 LED topological grid. A locking strategy is adopted so that subsequent frames skip repeated LED detection and clustering. The steady-state per-frame processing time is reduced to approximately 78.9 ms. Experiments covered 16 cross-combinations of vertical tilt from 0° to 45° (0°, 15°, 30°, 45°) and in-plane rotation from 0° to 40° (0°, 15°, 30°, 40°). The uncorrected scheme and the horizontal-box scheme experienced severe bit errors or complete failure under complicated distortion. The proposed scheme maintained error-free transmission under all 16 tested conditions. The ratios of opposite sides of the corrected LED grid remained stable between 0.997 and 1.004. The system simultaneously achieves high reliability and low-latency real-time processing under complex geometric distortions. Full article

Background/Objectives: Lung cancer is a leading cause of cancer-related mortality worldwide. As patients increasingly utilize large language models (LLMs) for health information, evaluating the readability and patient-centeredness of these tools is critical. This study aims to compare the performance of ChatGPT-4o mini, Microsoft Copilot, and Google Gemini in providing lung cancer information, focusing on their utility for individuals with limited health literacy. Methods: In this cross-sectional study (March 2026), 30 responses to ten standardized lung cancer-related queries were analyzed. Outputs were assessed using JAMA benchmarks and mDISCERN for quality, the SMOG index for readability, and PEMAT-P for understandability and actionability. Inter-rater reliability was analyzed using intraclass correlation coefficients (ICCs). Results: ChatGPT-4o mini demonstrated superior readability, achieving a sixth-grade level (SMOG: 6.23 ± 0.72, p < 0.001). Gemini achieved higher JAMA scores, indicating stronger academic rigour. While PEMAT-P scores were highest for ChatGPT (63.7%), all models exhibited moderate mDISCERN quality. Inter-rater reliability was excellent for JAMA (ICC = 1.000) and PEMAT-P (ICC = 0.883), though moderate for mDISCERN (ICC = 0.365), reflecting inherent interpretative subjectivity in qualitative assessment. No hallucinations were observed. Conclusions: Current LLMs exhibit a trade-off between accessibility and academic rigour: ChatGPT favours patient-friendly readability, while Gemini emphasizes structured content. The observed inter-rater variability in mDISCERN underscores the complexity of standardizing qualitative AI evaluation. These findings suggest that LLMs function best as complementary aids rather than substitutes for physician-led communication. Full article

Historic urban districts are increasingly exposed to rapid urban transformation, resulting in the deterioration of heritage fabric, weakening of spatial identity, and disruption of everyday patterns of use. Although participatory approaches are increasingly recognised in heritage-led regeneration, many applications remain limited by the lack of analytical mechanisms capable of connecting community perspectives with spatial and behavioural evidence in a structured and practical manner. This study develops and applies a participatory decision-support approach based on the People–Place–Behaviour (PPB) framework within the historic district of El-Mokhtalat in Mansoura, Egypt. The study combines spatial documentation, behavioural observation, and stakeholder consultation to examine how everyday urban practices, adaptive reuse, informal interventions, and local perceptions collectively influence regeneration priorities within the historic environment. The findings indicate that regeneration priorities emerge through the interaction between spatial conditions, community perceptions, and behavioural patterns rather than through isolated physical conditions alone. Based on stakeholder consultations (n = 30), the analysis identifies a prioritisation gradient in which architectural conservation and environmental enhancement represent the most immediate intervention priorities, while adaptive reuse and public-space improvements remain dependent on contextual compatibility and local acceptance. The study also demonstrates the analytical value of behavioural evidence in revealing recurring spatial pressures, identity-related transformations, and everyday interaction patterns affecting the continuity of the historic urban fabric. By integrating participatory, spatial, and behavioural evidence within a unified evaluation process, the study proposes a context-sensitive analytical approach capable of supporting more informed and locally responsive heritage-led regeneration strategies.

Background/Objectives: Community hospitals can be a valuable and cost-effective resource for elderly people, especially in rural areas. Their aim is to promote self-reliance, prevent unnecessary hospital admissions, and facilitate rapid recovery after acute illness. The widespread adoption of intermediate care facilities helps alleviate hospital overcrowding by preventing clinical deterioration through advanced and continuous nursing care. An intermediate care unit was established in a rural area of central Italy. This study aims to describe the impact of a community hospital on patients’ functional status from admission to discharge, describing a real-life model. Methods: This single-center descriptive study examines trends in the quality of care provided. Data were retrieved from anonymized electronic clinical records. Statistical analyses were performed using descriptive statistics, paired t-tests, and Pearson correlation coefficients. Results: A total of 532 residents (mean age 80.7 ± 13.2 years; 61% female) were admitted to the community hospital between January 2022 and September 2025. The mean length of stay was 15.2 ± 7.6 days, with a mean improvement in Modified Barthel Index score of 5.24 ± 7.95 (p < 0.05). Most patients (81.8%) were discharged home, while 6.0% required hospitalization. No readmissions were recorded in 2025. Clinical risk events occurred only in 1.2% of the total. Nursing specialization increased during the study period, correlating with improved patient outcomes (R = 0.88). Conclusions: This descriptive cross-sectional study in a rural nurse-led intermediate care unit found relatively short lengths of stay, high rates of home discharges and modest, but statistically significant, improvements in functional autonomy.

Contemporary youth mental health challenges necessitate collaborative approaches to prevention and support. The Mental Health Ambassador (MHA) program was developed to equip youth and adults in mentoring programs with the skills and confidence to discuss and support youth mental health, with the broader goal of creating meaningful impact within their local communities. The 8-session MHA program involves group-based learning and a local youth-led advocacy project. This mixed-method pre-post pilot evaluation examined program acceptability, implementation experiences, and potential for effectiveness. Participants included youth aged 14–18 years (n = 9) and adult mentors (n = 11) from mentoring organizations across five counties in Minnesota. Quantitative surveys assessed mental health resource awareness, preparedness to address youth mental health concerns, confidence in engaging in mental health conversations, and confidence in providing resources and referrals. Post-program focus groups explored participants’ experiences, perceived benefits, and implementation challenges. Findings indicated that both youth and adult participants reported positive experiences with the program and demonstrated increases in resource awareness, preparedness to address youth mental health concerns, confidence in discussing mental health, and confidence in providing resources and referrals. Qualitative findings further highlighted the value of youth-led advocacy activities and identified key considerations for implementation within mentoring settings. Mentoring programs may represent an ideal context for equipping youth and adults to provide early, community-based support for youth mental health concerns. Full article
