The shift from the central place paradigm to the network paradigm in regional relation research emphasizes the need to elucidate the factors and mechanisms driving urban network dynamics. Leveraging firm-level big data—including a headquarters–branch relationships database (29,359 headquarters and 114,679 branches) and an investment relationships database (21,843 investing firms and 69,733 recipients)—this study constructs an urban network integrating both vertical and horizontal enterprise connections. Using exponential random graph models (ERGMs), it analyzes the influencing factors and driving mechanisms of urban network dynamics in the Yellow River Basin (YRB). This study found that the urban network in the YRB is characterized by multiple isolated “core–periphery” radial networks. Strong connections are concentrated within each province’s major cities and their immediate surroundings, while horizontal connections across provincial borders are weaker. From 2000 to 2020, the urban network has evolved from isolated “core–periphery” radial networks to corridor networks where some core nodes are interconnected. The urban network dynamics in the YRB result from the combined influences of the preferential attachment mechanism, the network self-organization mechanism, the multi-dimensional proximity mechanisms, and the geographical boundary effect. Enterprises tend to establish branches or investments in cities with spatial proximity and larger economic scales. Reciprocal and transitive structures significantly facilitate urban network formation. Additionally, institutional proximity, geographical proximity, cultural proximity, cognitive proximity, and geomorphological division all exert varying degrees of influence on enterprise connections between cities.

As university campuses increasingly open to the public and become integrated into urban tourism systems, campus spaces are evolving into institutionalized multifunctional environments shared by students and visitors. However, existing tourism conflict research has mainly focused on traditional resident–tourist relations, with limited attention to institutionalized educational spaces. Taking Hunan University in the Yuelu Mountain Scenic Area, Changsha, as a case study, this study develops a perceived conflict–place attachment–overall impact evaluation framework and tests it using data from 438 student questionnaires and structural equation modeling. The results show that perceived conflict significantly weakens place attachment and reduces students’ positive evaluations of campus tourism impacts, with place attachment serving as a significant mediator. More importantly, the effects are not uniform: only economic and social conflict significantly reduce place attachment, campus belonging amplifies rather than buffers the negative effect of perceived conflict, and study duration does not significantly moderate this relationship. In addition, students whose daily study or living spaces are closer to tourism core areas report stronger perceived conflict and greater vulnerability to its consequences. By showing that tourism conflict in campus spaces is selective and context-dependent, this study extends tourism conflict theory beyond conventional community settings and offers practical implications for conflict-sensitive, spatially differentiated, and student-oriented campus tourism governance.

This study examined the critical sustainability challenge of regional demographic decline in South Korea by analyzing how young people’s mobility decisions are intricately influenced by structurally and socially constructed meaning systems. Countering strictly economic deterministic views, this research posited that youth out-migration is a complex socio-cognitive process mediated by social representations of place—collectively constructed and circulated meanings attached to regions. Applying a secondary analysis of Q-sort data from 24 undergraduate students at a regional national university, the study integrated Q methodology with Social Representation Theory to systematically identify youth typologies regarding regional identity, territorial stigma, and local extinction. Participants sorted 44 statements encompassing place attachment, local consumption, cultural experiences, and policy effectiveness. Rigorous factor analysis revealed four distinct perception typologies: identity-based strategic mobility, conditional leaving based on internalized success norms, re-anchoring toward alternative lifestyles, and skeptical leaving rooted in profound institutional distrust. The findings empirically demonstrated that identical structural constraints can produce highly divergent mobility trajectories—ranging from active retention to complete resignation—depending entirely on the region’s socio-cognitive representation. This study demonstrates that local extinction is not merely a demographic condition, but a socially constructed framework of meaning and an object of social representation that shapes youth perception typologies and mobility judgments. Accordingly, moving beyond conventional technical interventions, meaning governance, and strategic communication are needed to help reimagine regional futures. Full article

Street soundscapes significantly shape communities’ environmental perceptions, behaviour and urban sustainability. Previous research has mainly focused on physical and acoustic aspects, while limited attention has been given to emotional and behavioural dimensions. This study explores how expert participants perceive street soundscapes through personal, physical, behavioural, and emotional dimensions, using international online focus groups with soundscape experts, urban planners, and policymakers (n = 12). Analysis followed a deductive thematic approach establishing four main a priori themes, with additional inductive coding used to refine these themes. The findings reveal that perception is shaped by contextual, cultural, temporal, multisensory, and environmental affordance factors. Notably, silence was found to carry a dilemma—perceived as either safe or unsafe depending on pedestrian density—and religious and cultural soundmarks were identified as evoking place attachment and belonging, areas largely overlooked in existing literature. These soundscapes were associated with emotional responses, including comfort, safety, restoration, and belonging, and with pedestrian behaviour encompassing mobility choices, coping strategies, and social interactions. Furthermore, seven out of ten Healthy Streets metrics were directly referenced by participants, highlighting the close relationship between acoustic environments and healthy streets design. Future studies should examine cultural, temporal, and spatial street characteristics and their effects on human behaviour and emotional responses. Full article

[Problem] Converting viral tourism popularity into long-term destination sustainability is a central governance challenge in the digital era. [Aim] This study aims to explicitly measure how emotional value mediates the transition from ephemeral online traffic to durable offline place attachment. [Methodology] Adopting a descriptive mixed-methods approach, data were collected through semi-structured interviews with 16 purposively selected participants (including tourists and locals) recruited via on-site intercepts and online snowball sampling. The inclusion criterion required active engagement with Harbin’s digital tourism discourse. Qualitative transcripts were coded using the NVivo 12 software and subsequently converted into panel data. Grey Panel Relational Clustering was then utilized to geometrically track tourist emotional trajectories. [Results] The analysis identified three structural tourist typologies—the Full-Link Empathy Type, Pragmatic Verification Type, and Traffic-Driven Co-conspirator Type—and revealed three corresponding synergistic paths driving online–offline integration: Virtual–Real Isomorphism, Complementarity, and Symbiosis. [Conclusions] The findings demonstrate that sustainable destination resilience depends fundamentally on the qualitative composition of emotional engagement across different tourist types, rather than sheer visitor volume. [Implications] This study contributes an empirically grounded, emotional value-driven framework to sustainable tourism theory, offering differentiated governance strategies for destinations navigating the volatility of platform-driven attention economies.

The psychological benefits of waterfront public spaces have become an important topic in environmental design and architectural research. However, existing studies have primarily focused on the direct relationship between physical environmental attributes and user satisfaction, with limited attention to the psychological mechanisms through which architectural design influences residents’ well-being. This study examines waterfront concert halls as a type of cultural architectural space and develops a theoretical model integrating environmental restoration theory and place attachment theory. In this model, waterfront design perception is conceptualized as a multidimensional construct including water visibility, water accessibility, water harmony, and water interactivity, while perceived restorativeness and place attachment are treated as mediating variables, and residents’ well-being as the outcome variable. Based on questionnaire data collected from 1345 urban residents across six Chinese cities and seven waterfront concert hall cases, and analyzed using covariance-based structural equation modeling, the results show that waterfront design perception has a significant positive effect on residents’ well-being. Perceived restorativeness and place attachment both play mediating roles and jointly form a sequential pathway through which environmental perception is translated into psychological and emotional benefits. These findings extend the understanding of waterfront design from objective spatial attributes to subjective experiential processes and provide empirical support for the design of waterfront cultural architecture aimed at enhancing the well-being of urban residents.

Conceptual ambiguity in People–Place Relationships (PPR) research limits consistent operationalization and cross-context comparability, particularly in under-represented cultural settings. This study develops an integrated, context-sensitive framework for assessing PPR in residential environments and empirically examines its measurement structure. The framework is applied in Damascus as a pilot context to assess its structural validity, internal consistency, and applicability. The methodological approach comprised two stages: conceptual development and empirical validation. First, two rounds of case-study analysis derived from a prior systematic literature review synthesized environmental (social and urban) and relational (cognitive, affective, attachment) dimensions into a coherent framework. Second, the framework was operationalized and tested using survey data from 1610 residents across Damascus districts. Six first-order indices and one composite PPR index were constructed and evaluated using exploratory factor analysis and Cronbach’s alpha with item–total correlation analysis. Results demonstrate a stable multidimensional structure that integrates evaluative environmental conditions with relational processes, moving beyond emotion-dominant interpretations of attachment. The framework advances existing approaches by linking theoretical constructs to empirically tested measurement dimensions. While further validation in diverse contexts is required, the results indicate that the model provides a coherent and adaptable basis for assessing residential PPR in socio-culturally complex urban environments.

This study develops and tests factor-based and holistic theoretical models to explain the relationships between Spatial Quality Satisfaction (SQS), Overall Dormitory Satisfaction (ODS), and Place Attachment (PA) in student dormitories. Data collected from 450 students residing in five state-run dormitories in Kırklareli, Turkey, via three 5-point Likert-type scales (validated by expert review and a pilot study), were analyzed using structural equation modeling, following exploratory factor analysis, confirmatory factor analysis, and Cronbach’s alpha validations. Findings from the factor-based Model 1 indicate that eight of the ten SQS factors do not significantly influence ODS and PA when considered individually, whereas “Emotional and Psychological Atmosphere” and “Flexibility of Use” emerge as key determinants. Additionally, this model reveals that ODS has a strong and positive effect on PA. Results from the holistic Model 2 demonstrate that SQS, when treated as an integrated construct, has a robust and significant effect on both ODS and PA, with ODS playing a significant mediating role in the relationship between SQS and PA. Overall, the findings suggest that students perceive spatial quality as a whole. Therefore, improving student dormitories through a holistic SQS approach is more effective in enhancing PA and ODS than interventions focused on individual spatial dimensions. Full article

People spend most of their time indoors, highlighting the importance of indoor environmental quality for health and wellbeing. While previous studies have shown that exposure to nature can benefit wellbeing, much of this research has focused on outdoor environments, and less is known about how indoor plants and their spatial characteristics influence human perceptions and experiences. This paper reports on a survey study exploring how perceived health and wellbeing are influenced by indoor plants and human preferences for their characteristics, spatial arrangement, and other features within indoor environments. Indoor plants serve as visual and multisensory environmental stimuli. By examining the relationship between indoor plants, preferences, perceptions, visual comfort, multisensory experiences, and wellbeing, the study aims to understand these influences. The questionnaires include multiple-choice questions, yes-no questions, and open-ended questions, allowing the collection of both quantitative and qualitative data. The survey findings highlight the unique benefits of indoor plants, emphasising their potential to enhance wellbeing in ways that outdoor nature may not fully replicate in indoor settings. One significant finding of this study is that scattering indoor plants throughout a space can enhance the connection to nature through three-dimensional spatial interaction, potentially improving wellbeing. This arrangement may serve as a bridge to the outdoors, providing a psychological link to the natural environment. Crucial preference factors also include the complexity and coherence of indoor plants’ appearance, such as colour, shape, and size. The results further indicate that students prefer indoor plants over other elements such as cut flowers, fake plants, or artificial plant representations. The findings indicate that caring for indoor plants may foster emotional engagement, a sense of fulfilment, and place attachment through everyday interaction. In public spaces, plants may also enhance feelings of refuge and perceived security. These findings provide practical recommendations for designing indoor environments that enhance student wellbeing and human–environment interaction. Full article

Dark current represents a fundamental limiting factor in photodiode performance, establishing the noise floor and constraining detectivity in low-light applications. This comprehensive literature review examines publications covering the physical mechanisms underlying dark current generation and diverse techniques employed for its reduction. Covered mechanisms include diffusion current, Shockley–Read–Hall (SRH) generation–recombination, trap-assisted tunneling, band-to-band tunneling, and surface leakage, each examined with respect to its physical origin and characteristic signatures. Reduction strategies are categorized into thermal management approaches, surface passivation techniques including atomic-layer-deposited aluminum oxide (ALD Al₂O₃), guard ring architectures (attached, floating, and combined configurations), gettering and defect engineering methods, doping profile optimization, bias voltage management, and advanced device architectures such as pinned photodiodes and black silicon structures. A classification table organizes all the reviewed literature by material system, reduction technique, and key findings. Special emphasis is placed on silicon, germanium, III–V compounds, and emerging material photodiodes relevant to near-infrared detection, CMOS imaging, single-photon avalanche diodes (SPADs), and Time-of-Flight (ToF) applications.

This study examines whether improvements in quality of life (QOL) require increased household energy consumption (HEC) among low-income households in India by using a comparative analysis of Delhi and Kharagpur. A survey of 879 households (Delhi: n = 539; Kharagpur: n = 340) was conducted, and structural equation modelling (SEM) was applied to analyse the relationships between HEC and key QOL constructs, including residential satisfaction, economic satisfaction, and place attachment. The results indicate that QOL is primarily influenced by socio-psychological and housing-related factors rather than energy consumption alone. In Delhi, QOL is significantly associated with place attachment (β = 0.49, p < 0.001), economic satisfaction (β = 0.33, p < 0.001), and residential satisfaction (β = 0.13, p < 0.05), with the model explaining 42% of the variance (R² = 0.42; RMSEA = 0.048; CFI = 0.94). In Kharagpur, economic (β = 0.61) and residential satisfaction (β = 0.52, p < 0.001) show comparatively stronger effects. Although HEC is strongly associated with appliance ownership and cooling-related practices, it does not show a corresponding relationship with perceived QOL. Descriptive results further show higher well-being in Delhi (M = 3.85 vs. 3.42; d = 0.54). Overall, the findings suggest that differences in QOL between the two cities are more closely linked to socio-economic and residential conditions than to variations in household energy use, highlighting the importance of contextual factors in shaping well-being outcomes.

This study employs a reflexive autoethnography, guided by flow and place attachment theory, to examine how gaming experiences influence attachments to virtual environments and inspire real-world travel intentions. Data comprise reflexive journal notes written over a 10-month period after playing multiple video games and analysed using reflexive thematic analysis following a hybrid deductive–inductive approach. The analysis identified eight themes across three dimensions: temporal immersion, escapism, narrative immersion, and self-expression under flow; emotional, cognitive, and behavioural attachment under place attachment; and place-induced travel intention as the behavioural outcome. The findings establish flow as a critical antecedent to the development of place attachment within virtual environments. Consistent with emerging scholarship, the study confirms that attachment formation does not require physically tangible places; rather, it can emerge through digitally mediated presence and interaction, indicating that virtual environments are capable of eliciting place attachment. More significantly, it demonstrates that these virtual attachments can fluidly extend toward real places depicted in games, revealing a cross-environmental continuity in attachment processes. The integrated framework thus contributes a novel theoretical proposal linking flow, virtual and real place attachment, and tourism behaviour, an area that remains conceptually fragmented and empirically underdeveloped.

With non-rainfall water (NRW), principally dew and fog, serving as an important water source, especially in arid and semiarid regions, factors that may increase the NRW yield may have important hydrological and ecological consequences. On the other hand, dew and fog may also have hazardous effect on inorganic and human-made materials that may undergo corrosion and/or degradation. It has long been noted that dew and fog are affected by neighboring objects, the effect of which was, however, only barely explored. Hypothesizing that it may principally be linked to the sky view factor (SVF) (determining, in turn, substrate temperature and heat flow) and, therefore, to the angle that is formed between the collecting substrate and the height of the neighboring objects, a set of square boxes (30 × 30 or 60 × 60 cm) was constructed. The boxes had variable heights, forming angles of 15°, 30°, 45°, 60°, and 75° between 6 × 6 × 0.1 cm cloth attached to a substratum (10 × 10 × 0.2 cm glass plate overlying 10 × 10 × 0.5 cm plywood) at the center of each box and the top walls of the box. NRW that accumulated at the cloths was compared with cloths placed in the open, serving as control. Another set served to measure the plate temperatures. A clear decrease in NRW, with an angle corresponding to a third-degree polynomial equation, was found (r² = 0.998). Taking 0.1 mm as the threshold for vapor condensation (dew), and taking the average maximal NRW as measured for two years in the Negev (0.20 mm), angles of ≥45° will suffice to impair condensation. However, with the projected decrease in NRW with global warming, even angles of ≥30° may impair condensation in 1–2 decades. While it may decrease the dew amounts and subsequently negatively affect the vegetation in forest clearings and wadis or canyons, it may decrease the exposure of construction materials to corrosion and/or degradation, thus exerting a positive effect on construction materials in urban settings.

Ultrasonic motors have attracted considerable attention in precision actuation applications because of their advantages over conventional electromagnetic motors, such as compact structure, high positioning accuracy, immunity to electromagnetic interference, noise-free operation, and suitability for low-temperature environments. However, conventional traveling-wave linear ultrasonic motors usually rely on boundary constraints to establish stable traveling waves, which may limit their structural flexibility and self-propelled capability. To address this issue, this paper proposes a free-boundary traveling-wave linear ultrasonic motor capable of realizing self-propelled motion. The motor features a projection structure at each end of the stator. Two piezoelectric ceramics are placed at one end for excitation, while a damping material is arranged at the other end for energy absorption. This design enables the motor to generate traveling waves without requiring fixed boundary conditions. The motor operates in the B(3,1) out-of-plane vibration mode to enhance the energy absorption capacity of the non-excited end and reduce its standing wave ratio (SWR). A finite element model of the motor is established to investigate its vibration characteristics. In addition, a novel method for estimating the standing wave ratio is proposed by using piezoelectric ceramics attached to the motor surface, replacing the traditional calculation approach. A prototype is fabricated to verify the feasibility of the proposed design. Experimental results show that the prototype achieves a minimum SWR of 1.81, a no-load speed of 42.1 mm/s, and a maximum output force of 0.465 N. These results confirm the feasibility of the proposed scheme and provide a new approach for the design of free-boundary traveling-wave linear ultrasonic motors. Full article

Historic streets, as living heritage environments, preserve everyday cultural practices while facing increasing digital mediation in tourism and daily life. This study examines how a digital sense of place is constructed online in the Ming–Qing Old Street of Songyang, China. User-generated text and image data were collected primarily from Weibo, supplemented by user reviews from major travel platforms, including Dianping, Fliggy, Mafengwo, and Ctrip, and analysed through a multimodal framework. BERTopic was applied to identify thematic narratives in textual content, and ResNet-50 was used to classify visual scene elements in shared images, enabling an integrated interpretation of textual and visual representations. The results reveal four dominant dimensions of digital place perception: local food culture, living handicrafts, historic spatial fabric, and everyday atmosphere. Textual narratives emphasise emotional attachment and experiential interpretation, while visual representations highlight photogenic, performative, and shareable street scenes. The integration of these modalities forms a layered digital sense of place grounded in cultural continuity and daily life. The study demonstrates the value of multimodal social media analysis in understanding how living heritage streets are digitally represented and perceived, offering implications for sustainable heritage conservation, community-centred revitalisation, and data-informed cultural tourism management.
