Background: Food insecurity is defined as having limited access to food, while nutrition insecurity is characterized as a lack of consistent access to affordable and acceptable foods that support health, manage or prevent disease, and meet daily nutritional needs. College students face increased risks of food and nutrition insecurity, yet the issue is understudied. This study examined the patterns of food and nutrition insecurity among students at a public university across main and regional campuses. Methods: We conducted a cross-sectional survey using Qualtrics for participant recruitment in November 2023. The USDA’s 10-item toolFood insecurity was measured using the USDA’s 10-item tooland housing security was measured using the U.S. Census Bureau’s National Survey of Income and Program Participation 6-item tool. We used ANOVAs and logistic regression to examine differences across demographics. Data analysis was done using SPSS version 29. Results: There were 6538 student responses. Of these, 36% of students were food insecure, while 20% were nutritionally insecure. Comparatively, food and nutrition insecurity were significantly higher among students with low-income (p < 0.001), housing instability (p < 0.001), a higher number of dependents, and those indicating that they were single/unmarried (p = 0.005), first-generation (p < 0.001), and Pell grant eligible (p < 0.001). Annual income and housing security emerged as significant predictors: lower income was approximately twice as likely to be associated with food insecurity, while those reporting housing insecurity were six times more likely to experience food insecurity. Conclusions: The study findings reveal disparities in food and nutrition insecurity among a diverse student population at a public university. Addressing the issue among them is crucial and requires a multifaceted, inclusive approach. Emergency financial assistance and structural interventions that promote housing security are warranted.

Radon is the most important of all sources of natural radiation, and it belongs to the main air pollutants in closed space. It is necessary to develop awareness of its harmful effects in buildings in order to take appropriate measures to reduce the risk of exposure to it. This study assesses public awareness of radon-related risks in Serbia by analyzing four areas: general public, legislative framework, professional practices, and student knowledge. Data were collected from media sources, legal documents, conferences and scientific publications, and surveys among students of University of Belgrade. Student answers have shown that they are not aware of the danger of radon in buildings: there is a gap between knowledge about radon and about its effects in the interior space. The results also show low presence of this topic in the media and in professional circles in Serbia. This paper is a contribution to the overall efforts to spread awareness in Serbia about the problem of the presence of radon in closed spaces and the health problems it can cause. This is also important in the context of the search for energy-efficient building solutions, where the passive house is emerging as the most sustainable form. It is a relatively new concept in Serbia, so information about the harmful effects of radon in indoor spaces and about the implementation of certain strategies in passive construction for protection against radon is necessary in order to protect the health of the environment and the population.

Background/Objectives: Variations in staining styles—arising from differences in tissue preparation, scanners, and laboratory protocols—severely compromise the robustness of automated cell segmentation algorithms in digital pathology. Moreover, manual nucleus annotation is extremely labor-intensive, leading to a scarcity of large-scale, fully annotated datasets for supervised nucleus segmentation. This study proposes a novel framework that simultaneously mitigates staining variability and achieves high-accuracy nucleus segmentation using only minimal annotations. Methods: We present 3SGAN, a multi-task dual-branch generative adversarial network (GAN) that jointly performs stain normalization and nucleus segmentation in a semi-supervised manner. The framework adopts a teacher–student paradigm: a lightweight teacher model (AttCycle) equipped with attention gates generates reliable pseudo-labels, while a high-capacity student model (TransCycle) leveraging a hybrid CNN–Transformer architecture further refines performance. 3SGAN was trained and evaluated on a large dataset of 1408 Whole-Slide Images (WSIs) from two medical institutions, encompassing 101 distinct staining styles, with nucleus-level annotations required for only 5% of the data. Results: 3SGAN significantly outperformed state-of-the-art methods, achieving superior segmentation accuracy with an F1-score of 0.8140, mean IoU of 0.8201, and AJI of 0.6915. Simultaneously, it demonstrated substantial improvements in stain normalization quality, yielding a low RMSE of 0.0908, high PSNR of 21.0615, and SSIM of 0.8556 on the internal test set. External validation on independent MoNuSeg and PanNuke datasets, as well as on previously untested tumor-rich non-ROI regions from our in-house WSIs, confirmed strong generalizability with excellent stain normalization and top-tier segmentation accuracy across diverse staining protocols, tissue types, and pathological patterns. Conclusions: The proposed 3SGAN framework demonstrates that high-performance nucleus segmentation and stain normalization can be achieved with minimal annotation requirements, offering a practical and scalable solution for digital pathology applications across diverse clinical settings and staining protocols.

Background and Objectives: Social Determinants of Health (SDoH) are factors that can contribute to health inequities. Improving the conditions in which people are born, grow, and live requires collaboration between professionals from different health sectors. Given their health and well-being-focused care, nurses are crucial to promoting health equity in the care they provide. Thus, their knowledge, attitudes, and actions—i.e., practice—(KAP) regarding SDoH could serve as a helpful starting point for promoting care that also focuses on non-medical factors. This study aims to map the SDoH assessed in the literature in relation to nurses’ and nursing students’ KAPs, using the Dahlgren–Whitehead Rainbow Model as a logical framework. Methods: Following PRISMA guidelines, a systematic literature review was conducted using PubMed, Scopus, Web of Science, CINAHL, and PsycINFO. Records published until June 2024 were selected from primary studies involving nurses and nursing students, with no time limits. The assessed determinants were adapted and categorised according to the Rainbow Model Levels. Results: 22 results were eligible. The SDoH (in general), poverty, social justice, social gradient, social inclusion and exclusion, discrimination, diversity, equity and inequality, food insecurity and access to nutritious food, employment status, geographical isolation, healthcare services, housing difficulties, transportation, social support, individual lifestyle factors, and health literacy were assessed on KAPs. Conversely, health equity has been assessed just for knowledge and attitudes. Considering the latter level of the Rainbow Model and the relative categorisation of the results, age, sex, and constitutional factors were not examined in the studies included in this review. Conclusions: This review maps the most and least frequently assessed SDoH in relation to KAP. As nurses are essential to providing care that considers SDoH, improving health outcomes, and addressing health inequities, and advocating for community health, it would be valuable to enhance nursing education from baccalaureate through postgraduate courses. Moreover, a strong relationship with different healthcare professionals is needed. Full article

Since children spend a significant portion of their developmental years in educational settings, the environmental quality of these institutions—specifically, the extent to which they expose their occupants to green space and heat stress—is a critical determinant of well-being and academic performance. This study assesses the green environmental quality of 121 educational institutions (kindergartens, and elementary and secondary schools) in Debrecen, Hungary. The main objective of the research is to identify educational institutions that require immediate intervention to address their lack of green spaces, improve the green environment, and mitigate the urban heat island (UHI) effect. A further aim of the study is to understand how different urban planning practices over the past century have led to the current situation. Therefore, we utilized high-resolution geospatial data (specifically, WorldView-2 imagery) to classify schoolyard vegetation; Landsat data to derive Land Surface Temperature (LST); and the Hoover index to quantify institutions’ spatial concentration. We developed a composite indicator to categorize green environmental quality and heat stress exposure. Our results reveal deep spatial and institutional inequalities. 47.5% of students attend institutions with low environmental quality. While kindergartens typically offer green-rich environments, secondary schools with significant student populations—which are primarily concentrated in the dense historical downtown—are trapped in “grey” zones possessing poor environmental quality. Furthermore, we identify a “green paradox” in socialist housing estates: despite abundant surrounding greenery, schools here record high LST values due to the heat-trapping morphology of vertical concrete structures. The study also highlights institutional maladaptation, such as converting schoolyards into parking lots and using rubber pavements for safety reasons, which contributes to the deterioration of environmental quality. We conclude that current urban planning and school architecture must shift paradigms, treating schoolyards as integral components of the public green infrastructure network through climate-adaptive design. In addition, stakeholders should develop the green environment of educational institutions comprehensively, taking into account both on-site and surrounding green spaces. Full article

Kennel-raised dogs are exposed to more stressors and fewer positive experiences than dogs raised in homes. We created a Dog Socialization and Training class to enrich the environment of university teaching dogs. Undergraduate students (103 total) were assigned a dog (64 total) to socialize and train for at least 36 30 min periods across 12 weeks. Each student used a Qualitative Behavior Assessments (QBA) tool to score 20 different behaviors on a scale of 0 to 125 for his/her dog at the beginning (PRE) and the end (POST) of each of the nine semesters. The PRE QBA scores were high for the ten positive valence behaviors including Relaxed (mean ± SE: 75 ± 6) and low for the ten negative valence behaviors including Distressed (31 ± 3). Following the interactive experiences, QBA scores for all 20 behaviors appeared to improve from 9% to 53% (p < 0.006). Principal Component Analysis identified four dimensions in the QBA scores that were responsible for most of the data variance. Providing kennel-housed dogs with regular, positive human interactions was perceived to increase the dogs’ positive valence towards humans and reduced negative responses. These benefits are expected to enhance the dogs’ teaching effectiveness with veterinary students, adoptability, and future adaptation to new forever homes. Full article

This article examines how everyday architecture can advance spatial justice in post-active conflict cities through ethnographic and participatory design. Drawing on a decade of work by the StreetSpace studio in Belfast (2015–2025), the paper explores how architecture students and community participants co-design spatial strategies that enhance mixed-use mid-density living, inclusive mobility, and street-level accessibility. In a context where car dominance, segregation, and privatisation of public space continue to fragment urban life, the everyday street becomes a testbed for envisioning an equitable and community-centred city. The studio’s methodology is grounded in ethnographic engagement, informed by an embedded anthropologist, and includes stakeholder mapping, walking workshops, and collaborative drawing. These practices reveal lived experiences and shape community-driven briefs for housing, schools, public spaces, and multifunctional infrastructure. Anchored in spatial justice discourse and feminist theory (Jane Jacobs, David Harvey, Roberto Rocco, Phil Hubbard, Leslie Kern, and Caroline Criado Perez), the work positions the everyday as a site of architectural agency and proposes a contemporary vernacular that is socially embedded and climate-resilient. This work unfolds through complex and often contested processes that require sustained, iterative engagement with people and places. Meaningful collaboration is neither linear nor inherently caring; it frequently involves conflict, disagreement, and competing priorities that must be navigated over time. Through long-term relationships with government departments, local authorities, and NGOs, StreetSpace demonstrates how architectural pedagogy can nonetheless contribute to policy formation and more inclusive urban redevelopment by engaging in compromise, critical negotiation, and moments of care alongside friction and resistance. Through a series of collaborations and public events the project has contributed to the transformation of Botanic Avenue, informed studies of the East Belfast Greenways through contributions to Groundswell and participated in embedded public processes in collaboration with PPR, culminating in an exhibition at the MAC in Belfast in 2025.

Objectives: We aimed to develop expert-informed recommendations for colleges and universities to support students with celiac disease (CeD) managing a gluten-free (GF) diet. Methods: A multidisciplinary panel of 40 stakeholders, including physicians, dietitians, a disability rights attorney, university staff, and students, was convened by the Celiac Disease Foundation to create expert-based and experience-informed recommendations. Over a 6-month period, the group conducted literature reviews, stakeholder interviews, and expert consensus discussions to identify common barriers and accommodations aligned with federal disability law. The expert panel collaboratively developed and revised an initial set of recommendations. Two rounds of structured voting were held during which panelists provided feedback to refine content and ensure clarity. All final recommendations were adopted with at least 90% of panelists voting in support. Results: The panel identified 24 accommodations across four domains: academics, housing, dining, and campus life. Academic recommendations include flexibility for illness-related absences, support for remote learning, and classroom modifications. Housing recommendations emphasize access to priority placement, appropriate appliances, and proximity to safe dining. Dining accommodations address GF food availability, ingredient transparency, staff training, and meal plan flexibility. Campus life recommendations ensure full participation in athletics, study abroad, social events, and internships, with supports for psychosocial well-being. Conclusions: This manuscript presents the first expert-informed recommendations focused specifically on the needs of college students with CeD. These recommendations are intended to support institutions as they develop strategies to enhance access to GF food, quality of life, educational supports, and student experience for those living with this chronic autoimmune condition.

Ultrasound-guided femoral vascular access (UFVA) is a crucial step in cardiovascular intervention, yet training models remain costly, anatomically limited, or insufficiently durable. This research aimed to develop and evaluate a reusable, self-healing vascularised leg phantom in collaboration with clinicians. This bifurcating vascular model was cast in Plastisol using a customisable silicone mould design. The material exhibited a Shore OO hardness of 18.0 ± 2.2, a speed of sound of 1454 ± 15 m/s, an acoustic attenuation of 1.66 ± 0.02 × 106 kg/m²s, and healed 18G needle lesions within 3 h. Training capabilities were evaluated in a workshop involving 18 medical students: FVA times improved by more than 60% after 5 min of free practice. Qualitative feedback was collected from 31 medical educators via a seven-question Likert survey, with most reporting they would adopt the phantom for teaching. Phantoms cost £7.87 for materials, yet educators valued the models at £100–£500, underscoring its perceived utility. Compared to commercial alternatives, this in-house production approach reduced costs by 10–60 times, achieving comparable durability and anatomical fidelity. This study establishes a scalable, ultra-low-cost method for producing anatomically realistic, self-healing vascular phantoms, validated for effective skill acquisition in both educational and research settings.

This study investigates why Generation Z in Surabaya remains reluctant to live in vertical housing despite strong urbanization pressures and policy promotion. Using an explanatory sequential mixed-methods approach with 340 respondents aged 18–27, the research identifies five key factors influencing preferences: physical environment, psychological-social concerns, social status and stress, economic considerations, and cultural accommodation. Factor analysis explains 45.1% of total variance, while structural equation modeling reveals that physical environment preferences play a central mediating role. Economic factors affect psychological-social concerns both directly and indirectly, and cultural accommodation strongly shapes social status perceptions but does not directly influence physical preferences. Qualitative analysis of 411 statements shows consistently negative psychological themes, predominantly negative economic sentiments, and more balanced views of physical attributes. Subgroup analysis reveals stronger economic effects among early-career professionals than students. The findings challenge purely rational housing choice models, demonstrating that cultural and economic factors shape psychological acceptance through indirect pathways. Recommendations include culturally sensitive designs (flexible guest rooms, communal gathering spaces), innovative ownership schemes (rent-to-own, cooperative models), and reframed marketing emphasizing lifestyle enablement rather than amenity features.

The TV series Architecture School depicts entanglements between design (education), urban development, and the complexities of everyday life through its presentation of students in a program of “public-interest” design–build education (wherein students plan and construct homes for low-income families in post-Hurricane Katrina New Orleans). The series offers a nuanced presentation of the situated difficulties of critical design thinking in the context of creating contemporary homes: starting from the initial stages of sketching and model making, through construction, and finally to managing the occupation of the homes by persons who are typically underserved by contemporary architecture. We provide an analysis of the series through outlining how the show presents its participants (student designer-builders, non-profit housing administrators, potential homeowners). We focus on discussing instances of talk on the TV series to illustrate some of the specific concerns and contexts of these participants. Our aim is to explore Architecture School as a relevant case study in designing and building that reflects a dilemma underpinning much contemporary, urban, and public-interest design: how can socially and economically marginalized individuals acquire innovative, well-designed homes when structural conditions of government policies, financial protocols, and administrative complexity offer sustained constraint? We detail how the series depicts the students, administrators, and potential occupants to consider how stereotypes of architects, bureaucrats, and the working poor are reinforced or challenged. Accordingly, we argue that Architecture School is a cultural text that remains timely and important today for its presentation and critique of both the inside world of design’s aims to design and build for others and also the outside-world challenges that limit design’s capacities to create inclusive and equitable material conditions.

On 19 December 2015 and 21 February 2017, Longyearbyen was hit by major avalanches from the steep hillside of the mountain Sukkertoppen. In this article, we specifically consider the 2015 avalanche that destroyed eleven houses and buried nine people; seven were located and rescued, while two died. We describe the meteorological conditions leading up to the avalanche, the rescue operation, the media coverage, and the immediate aftermath of the catastrophe. Both events came as a result of warming, strong easterly winds, and drifting snow, with the December 2015 event being the most extreme. The 2017 avalanche damaged two houses, but no people were hurt. We analyse the catastrophes in relation to the knowledge of the risks and impacts of avalanches in Longyearbyen, as provided through field-based student courses at the University Centre of Svalbard (UNIS). To protect against further avalanche accidents, parts of Longyearbyen have been restructured, and physical barriers against avalanches have been installed on the hillside of Sukkertoppen. Now there are snow drift fences to reduce snow accumulation in the release areas, avalanche protection fences mounted in the hillside, and a large wall at the foot of the mountain to catch avalanche debris in the future. In hindsight, the accidents have contributed to an increased national awareness of the danger of severe weather events. Full article

University campuses are key testbeds for circular and climate-resilient transformation. This study evaluates how redevelopment strategies at eight Finnish campuses align with long-term environmental and social goals using indicators derived from the New European Bauhaus (NEB) framework. A mapping and qualitative synthesis of 97 peer-reviewed publications (2015–2024) was combined with a comparative analysis of sustainability strategies, carbon-neutrality roadmaps, and campus development strategies (2010–2024). Indicators were formulated based on campus-specific challenges and NEB core values—sustainability, inclusion, and esthetics—and operationalized across five areas: blue-green infrastructure, low-emission mobility, student housing, carbon reduction and renewables, and cultural heritage/community integration. Results show strong commitments to energy efficiency, mobility, and biodiversity. However, socio-spatial dimensions—student housing, participatory inclusion, and place identity—are weak or externalized. Reporting practices are uneven, and metrics are not standardized, limiting comparability across institutions. We argue that SDG-based monitoring should be complemented by NEB’s place-sensitive criteria to bridge strategy–implementation gaps and to future-proof campus redevelopment. An illustrative conceptual case for Helsinki’s Viikki campus demonstrates how the indicators can be integrated into design scenarios. Policy recommendations highlight how integrating NEB’s place-sensitive criteria with ESG/SDG frameworks can strengthen the strategic and spatial coherence of campus transformations. Full article

This paper presents the design, implementation, and validation of an IoT-based geolocation system using the Sigfox network to enhance student safety in urban environments. The proposed system integrates a GPS NEO-6M module with a Ufox Devkit, enclosed in a portable housing, to provide low-power and real-time location tracking. A comparative evaluation of three visualization platforms identified Traccar as the most suitable solution, offering superior accuracy, interoperability, and response time. Field tests were conducted in five educational institutions in Ambato, Ecuador, achieving an average geographic accuracy of 4.5 m and operational efficiency ranging from 55% to 78%, depending on network coverage and urban interference. These results demonstrate the feasibility of Sigfox-based geolocation for reliable student monitoring and provide practical insights for deploying scalable, cost-effective safety solutions in educational contexts.

The 15 min city concept seeks to promote health, well-being, and quality of life by ensuring that essential services are located within a 15 min walking or cycling distance from housing and are accessible through sustainable modes of transportation. This study aims to evaluate the compliance of this concept in a developing country context and provide supporting evidence by examining if residing within the 15 min reach to basic services affects perceived health, perceived accessibility, and life satisfaction. To assess pedestrian accessibility in Lahore, Pakistan, we adapted the NEXT proximity index—originally developed as part of the Landscape Metropolis Project in Italy—which scores 15 min access using open data sources. A network analysis was conducted to determine the shortest travel times to various points of interest, including education, transportation, healthcare, shops, restaurants, leisure spaces, places of worship, and financial services. Each hexagonal unit in the study area was assigned an access score proportional to its proximity to these facilities. These access scores were then analyzed using multiple regression models, based on survey data collected from 519 university students regarding their perceived health, perceived accessibility, and life satisfaction. According to the network analysis conducted using WorldPop estimates of Lahore’s population, only up to 30% of the population resides in areas that qualify as a 15 min city for each facility type. Moreover, access to bus stops significantly enhances both perceived accessibility and life satisfaction, while proximity to healthcare services shows the strongest positive association with life satisfaction.
