Geographical exclaves face distinctive development challenges as spatial separation creates cross-border dependencies and institutional vulnerabilities. Musandam Governorate, Oman’s exclave separated from the mainland by United Arab Emirates (UAE) territory, exemplifies how exclave status shapes development trajectories, cross-border interactions, and population resilience. This study examines Musandam’s socio-economic dynamics, development patterns, and cross-border relationships, addressing gaps in understanding how exclave residents navigate spatial discontinuity while maintaining mainland and cross-border connections. Mixed methods combined quantitative assessment using the adapted Vera Carstairs Index (VCI) across seven domains (education, skills, employment, housing, living environment, household facilities, health) with qualitative fieldwork spanning four campaigns (2019–2023). Semi-structured interviews with 47 residents across all four wilayaat (provinces), complemented by citizen science approaches engaging twelve community participants, documented mobility patterns and cross-border transactions. Secondary data from the 2010 Population Census and national statistics provided contextual depth. Findings reveal two of four Musandam wilayaat (Daba and Khasab) ranking in the lower half nationally, with low health scores (ranks 1 and 9) and education institution deficits reflecting structural integration into transnational economic and services systems. COVID-19 border closures amplified pre-existing dependencies, converting eight-month isolation into a humanitarian crisis with food shortages, medicine unavailability, and social fragmentation. Residents maintain stronger functional connections with UAE cities than with mainland Oman despite preserving national identity. Policy implications emphasize six strategic priorities: higher education institutions, transportation infrastructure, marine fisheries development, tourism enhancement, small-medium enterprise facilitation, and residential land provision.

Cross-border greenfield investment in the financial services sector is increasingly understood not as isolated flows, but as a complex, dynamic global system. This systemic perspective is essential for understanding its holistic structure and evolution amidst globalisation and digital transformation. This paper utilises financial services greenfield investment projects from 100 major economies from 2003 to 2021 to construct the Global Financial Services Greenfield FDI Network (GFS-GFN). By combining Social Network Analysis (SNA) and Temporal Exponential Random Graph Models (TERGMs), we systematically investigate its dynamic evolutionary features and endogenous mechanisms. The findings reveal the following: (1) System-wide, the network exhibits persistent expansion, “small-world” properties, and a pronounced “rich club” effect among source countries. (2) Nodally, the structure has evolved from a US-UK “dual-core” to a multipolar configuration, as emerging hubs like China, the UAE, and Singapore rapidly approach the traditional centres. (3) Structurally, the network has fragmented from Euro-American dominance into five major communities, forming a diverse, complementary pattern. Network evolution is primarily driven by endogenous mechanisms. Investment relationships widely exhibit reciprocity, preferential attachment, transitive closure, and marked path dependence.

This paper examines the humanitarian, social, and economic disruptions resulting from the 2023–2024 closure of the Lukeville, Arizona, Port of Entry (PoE). Drawing on collaborative ethnographic fieldwork, including semi-structured and informal interviews, observation, and participation in local community events, we examine how a rural, unincorporated community handled a historic border closure. Further, we analyze how the closure impacted migrants, especially asylum seekers, who were excluded from protection due to bureaucratic and discretionary decision-making. The closure not only disrupted asylum access but also humanitarian aid networks, local economies, cross-border families, and Indigenous sovereignty, producing a geography of sanctioned neglect. These findings demonstrate how federal enforcement decisions, often made without considering borderland communities’ realities, frequently lead to their further destabilization while these areas are already navigating structural abandonment. We conclude with recommendations emphasizing harm reduction and preparation practices to mitigate future disruptions. Full article

Introduction: Pediatric lower-lip dog bite injuries are challenging due to contamination, tissue loss, and the need to maintain function, appearance, and psychological well-being. This single case describes immediate definitive closure using sharp debridement with adjunct polyhexanide (PHMB), a full-thickness skin graft (FTSG), and a polyurethane (PU) compression foam bolster. Methods: A 10-year-old boy with a severe contaminated lower-lip defect underwent debridement and 0.04% PHMB irrigation. An upper-arm FTSG was inset and compressed with a suture-anchored PU dressing. Topical PHMB gel was used perioperatively and for seven days after bolster removal. Oral antibiotics were given for five days. The patient was discharged eight days after the injury with detailed wound care instructions. Results: Immediate definitive closure was achieved with complete graft survival and no infection, necrosis, unplanned early dressing changes, or reoperations. At 12 months, oral competence, speech, lip mobility, and contour were preserved. However, mild residual esthetic differences remained (dyschromia, shallow border indentation, vellus hairs on the graft). Conclusion: In this single descriptive case, primary closure of a lower-lip injury with the combined intervention was associated with an uncomplicated functional course and manageable esthetic trade-offs at 12 months. These observations are descriptive; comparative studies with standardized functional, esthetic, and psychosocial measures are needed. Full article

This study systematically reviews the academic literature on unpaid care work during and after COVID-19, emphasizing gender dimensions. Using Web of Science (WOS) and SCOPUS, it analyzes 75 empirical articles published between 2020 and 2024 in English and Spanish. The selection focused on studies addressing unpaid care from multiple perspectives, particularly family dynamics. Quantitative analysis examined frequencies and percentages, while qualitative analysis explored content depth. Results reveal a dominant biomedical perspective on care, often neglecting emotional well-being and broader socioeconomic impacts. The present study also identifies a lack of critical reflection on care’s gendered nature and unequal caregiving responsibilities. Women, historically burdened with care duties, faced increased domestic demands during the pandemic, due to school closures and limited services, exacerbating gender inequality and reducing workforce participation. A bibliometric analysis of research on COVID-19, gender, and social care highlights limited collaboration, with studies fragmented across research groups and lacking international co-authorship. This study calls for governmental and international initiatives to foster cross-border collaboration, enabling a more comprehensive understanding of care that integrates emotional and socioeconomic aspects alongside health concerns. This would promote a more inclusive and reflective approach to unpaid caregiving research. Full article

Tourism growth in the Cook Islands is broadly supported by residents, but evidence of social and environmental harm is mounting. This study examines the role that tourism plays in the dynamic processes of disorientation and reorientation related to tourism development in three islands: Rarotonga, Aitutaki, and Mitiaro. A total of 102 interviews were conducted at a critical juncture where Cook Islanders reflected on the pre-COVID-19 tourism boom and the subsequent shock of border closures. The findings highlight the undeniable economic dominance of tourism and opportunities for individual livelihoods. However, residents expressed that these must not come at the cost of other types of wellbeing, especially in tourism-heavy Rarotonga. A reorientation towards greater connectedness with culture, each other, and local environments was seen as essential. Cook Islanders expressed a need to take control of tourism in ways that are community-driven, balanced across economic/financial, physical, social, spiritual, and mental wellbeing, and in harmony with local carrying capacities.

Transboundary water pollution is a major global challenge as its movement and impacts remain unsurveyed. Monitoring pollution along international borders can reveal some of the pathways by which sewage and chemicals enter water bodies, and can hence advance the implementation of measures to prevent leakages and discharges into international waters. In this paper, we surveyed the impacts of sewage pollution and chemicals along the U.S.–Mexico international border, using Imperial Beach (California) as a main case study. Pollution was primarily attributed to the inflow of contaminated waters from the neighboring city of Tijuana (Mexico), where a malfunctioning wastewater treatment plant and a lack of sewage pipes being upgraded have caused direct leakage and toxic discharges into the Tijuana River. Reported effects from water pollution at the Tijuana River estuary in Imperial Beach include frequent beach closure, damages to coastal ecosystems, negative impacts on the fishery industry, and several effects on the health of beach users and surfers. Hence, the situation requires urgent measures oriented at coastal management at the mouth of the Tijuana River as well as the consistent monitoring and reporting of human health effects linked to beach uses.

Landfills for disposing of solid waste are designed, located, managed, and monitored facilities expected to comply with government regulations to prevent contamination of the surrounding environment. After the average life expectancy of a typical landfill (30 to 50 years), a large investment in the construction, operation, final closure, and 30-year monitoring of a new site is needed. In this case study, we provide a holistic explanation of the unexpected development of elevated temperature landfills (ETLFs), such as that in the city of Bristol (United States) on the border of the states of Virginia and Tennessee, including the initial role played by coal ash. Despite the increasing frequency of ETLF occurrence, there is limited knowledge available about their associated environmental problems. The study uses mixed (qualitative, quantitative, and mapping) methods to analyze (1) the levels of odoriferous reduced sulfur compounds, ammonia, and volatile organic compounds (VOCs) emitted, (2) the ratio of methane to carbon dioxide concentrations in five locations, which dropped from unity (normal landfill) to 0.565, (3) the location of gas well heads with gradients of elevated temperatures, and (4) the correlation of the filling rate (upward of ~12 m y⁻¹) with depth for registered events depositing coal ash waste. The work identifies spatial patterns that support the conclusion that coal ash served as the initiator for an ETLF creation. The case of the city of Bristol constitutes an example of ETLFs with elevated temperatures above the regulatory United States Environmental Protection Agency (EPA) upper threshold (65 °C), having alongside low methane emissions, large production of leachate, land subsidence, and a large production of organic compounds. Such landfills suffer abnormal chemical reactions within the waste mass that reduce the life expectancy of the site. Residents in such communities suffer intolerable odors from fugitive emissions and poor air quality becomes prominent, affecting the well-being and economy of surrounding populations. Conclusive information available indicates that the Bristol landfill has been producing large amounts of leachate and hazardous gases under the high pressures and temperatures developed within the landfill. A lesson learned, which should be used to prevent this problem in the future, is that the early addition of coal ash into the landfill would have catalyzed the process of ETLF creation. The work considers the public health risks and socioeconomic problems of residents exposed to emissions from an ETLF and discusses the efforts needed to prevent further incidents in other locations.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, continues to impact the world even three years after its outbreak. International border closures and health alerts severely affected the air transport industry, resulting in substantial financial losses. This study analyzes the global data on infected individuals alongside aircraft types, flight durations, and passenger flows. Using a Bayesian framework, we forecast the risk of infection during commercial flights and its potential spread across an air transport network. Our model allows us to explore the effect of mitigation measures, such as closing individual routes or airports, reducing aircraft occupancy, or restricting access for infected passengers, on disease propagation, while allowing the air industry to operate at near-normal levels. Our novel approach combines dynamic network modeling with discrete event simulation. A real-case study at major European hubs illustrates our methodology. Full article

Bordered pits in conifers have been recognized as a significant evolutionary characteristic that served to impede the spread of embolisms between tracheids. Nevertheless, there was a lack of comprehensive understanding regarding the mechanical properties of the torus and the pit border in relation to the formation of contact seals in aspirated pits. A solid mechanics model was developed to study aspirated bordered pits, incorporating the elastic deformation of the torus–margo structure and the contact behavior between the torus and the pit border. Ten pit samples were reconstructed using transmission electron microscopy (TEM) and scanning electron microscopy (SEM) pictures in order to develop mechanical models for pits in the stems of Platycladus orientalis. Due to the limited contact area on the torus surface, the contact pressure between the torus and the pit border exceeded the air pressure in aspirated bordered pits. The external force and the duration required to seal pits decreased when the pit diameter increased and the pit depth decreased. The augmentation of the torus and margo mass necessitated a lengthier duration for the closure of cavities. The findings presented in this study offered theoretical support for the capillary-seeding hypothesis. The aspiration in bordered pits mechanically depended on the structural and material characteristics of the torus and margo. Full article

Much research in forest ecology has been devoted to examining the effect of gap formation on regeneration dynamics. However, comparatively little research has examined the process of gap closure, in which larger trees bordering the gap grow laterally to exploit available light. Thus, it remains uncertain whether disturbance disrupts or reinforces the competitive hierarchy established among different species and sizes classes. We quantified the lateral growth of three hardwood tree species with differing autecologies both before and after the formation of small gaps created by single-tree selection. Linear mixed-effect models were employed to link lateral growth to species and stem diameter to examine whether gap formation favors intolerant species and small trees in the canopy. Additional models were also developed to examine the relationship of lateral growth with branch length and tree height. Before gap formation, the mid-tolerant yellow birch grew considerably faster than the tolerant sugar maple and American beech. However, yellow birch was less responsive to gap formation (~16%) than sugar maple or beech, whose lateral growth increased by 42% and 39%, respectively. This suggests that gap formation reinforces the competitive dominance of tolerant species. In contrast, gap formation disrupts the competitive dominance of large trees in the canopy, since the lateral growth of small trees increased five times that of large trees. Thus, small silvicultural gaps bordered by small trees may close too quickly to permit the regeneration of mid-tolerant species. Following the release, small trees also grew faster than their larger counterparts, suggesting that lateral growth declines as the cost of reproduction increases with tree size. However, lateral growth did not vary with tree height or branch length, suggesting that lateral growth does not decline due to increasing support costs or hydraulic limitation. Full article

The COVID-19 pandemic complicates ingrained educational inequalities around the globe and foregrounds the pertaining challenges that teachers have encountered due to school closures and the shift to distance learning. This cross-border teacher education project intended to examine how academics and pre-service teachers in different geographic locales could collaboratively explore equitable learning opportunities for diverse learners through the use of critical media literacies to respond to interconnected global crises. In this six-week cross-border teacher education project, we recruited four Mandarin and English literacy teacher candidates in Hong Kong to interact with one another and one Canadian professor as part of the teacher preparation phase of a larger-scale cross-border research project that connects youth from Hong Kong and Canada in a social networking space. For the purposes of teacher professional development, the Hong Kong teacher candidates and Canadian researchers engaged in collective exploration of how instructional designs in literacy education could promote equitable learning opportunities for diverse learners. Findings show that the cross-border teacher education project supported teacher candidates’ development of pedagogical skills and espoused their agency in promoting educational equity and collective problem-solving through critical media literacies. Findings relate the teacher candidates’ shifted perspectives from focusing on students’ decontextualized language skills to nurturing critical media skills. Changing from a deficit-oriented view about what literacy learners could not do, the teacher candidates also adopted an asset-oriented view about the linguistic and cultural repertoires that diverse learners could bring to literacy classrooms.

The city of Christchurch, New Zealand, incurred significant damage due to a series of earthquakes in 2010 and 2011. The city had, by the late 2010s, regained economic and social normalcy after a sustained period of rebuilding and economic recovery. Through the concerted rebuilding effort, a modern central business district (CBD) with redesigned infrastructure and amenities was developed. The Christchurch rebuild was underpinned by a commitment of urban planners to an open and connected city, including the use of innovative technologies to gather, use and share data. As was the case elsewhere, the COVID-19 pandemic brought about significant disruptions to social and economic life in Christchurch. Border closures, lockdowns, trading limitations and other restrictions on movement led to changes in traditional consumer behaviors and affected the retail sector’s resilience. In this study, we used CBD pedestrian traffic data gathered from various locations to predict changes in retail spending and identify recovery implications through the lens of retail resilience. We found that the COVID-19 pandemic and its related lockdowns have driven a substantive change in the behavioral patterns of city users. The implications for resilient retail, sustainable policy and further research are explored. Full article

Disruptions in the food supply chains caused by the COVID-19 pandemic have destabilized the balance between production, supply, transport, distribution, and consumption. Consequently, these disruptions have affected food and nutritional security all over the world. This study proposes a framework for investigating the impact of COVID-19 on food supply chains, considering Eastern Africa as a focus region with Kenya and Rwanda as case studies. A systems thinking approach with three systemic components (food and nutrition, COVID-19 contagion, and human health) was applied. The contagion component was characterized by the susceptible, exposed, infected, recovered, and deceased (SEIRD) epidemiological modeling method. We then applied a causal loop diagram and stock and flow diagrams to map the links and interactions between variables from the contagion, health, and food supply chain components of the whole system. The results reveal that COVID-19 has adversely affected food and nutritional security in Eastern African countries. Key response measures to COVID-19 such as lockdowns, closure of borders, isolation, and quarantining have resulted in labor shortages, increased unemployment rates, loss of income, and the subsequent contraction of economies. The disruption of the food supply chain has negatively impacted the main pillars of food and nutrition security, which are availability, accessibility, utilization, and stability. We suggest direct food supply from local producers to the consuming communities to shorten the food supply chain and therefore enhance food self-sufficiency to reduce the severe effects of COVID-19 on food and nutrition security. Overall, our study provides a useful framework to help design better policies and build more resilient and inclusive food systems during COVID-19 and similar pandemics in the future. Full article

Due to the globalization of the economy, studying abroad has been widely recognized as bringing many benefits to students. However, the closure of campuses and borders around the world since the COVID-19 pandemic, which began in 2020, has brought about significant changes in studying abroad as learning has moved online. In the context of emergency management, a new way of studying online has arisen. Despite this change, few studies have focused on the value perception of and satisfaction with online study abroad (OSA) in the context of the pandemic or have focused on students enrolled in overseas universities. To address this gap, this study proposed six research hypotheses and a hypothesis model based on the situated expectancy-value theory. The study used the snowballing technique to survey Chinese university faculty members who had studied online at overseas universities during the pandemic. A total of 481 valid data were collected, including 214 (44.5%) male and 267 (55.5%) female respondents. The data were then confirmed to have reliability and validity, and the research model was tested. Results indicated that all of the research hypotheses were supported. More specifically, the perceived value of OSA can be positively predicted by academic and career self-efficacy. Academic and career self-efficacy can be positively predicted by OSA motivation. The perceived value of OSA is positively related to satisfaction with OSA. This shows that promoting satisfaction with OSA for international students is a feasible international education program when international mobility is not possible in particular situations.
