At key phases of the crisis, tourist sentiment became more aligned, reflecting heightened uncertainty. Spatially, Kuta, Denpasar, and Ubud remained central hubs for both positive and negative sentiment, with persistent concerns regarding waste management and traffic congestion. Topic-based analysis highlighted strong positive sentiment toward ‘Attractions’ and ‘General’ tourism aspects, while ‘Accessibility’ and ‘Amenities’ received more criticism. Additionally, sentiment trends varied by nationality, with UK and US tourists expressing more negative sentiment, while Singaporean and Filipino visitors remained consistently positive.

Existing invasive species prediction (ISP) models typically utilize original data of environmental factors directly as inputs, which may introduce uncertainty into predictive outcomes due to inherent random errors in the data. However, such random errors are often overlooked in ISP modeling, potentially compromising the reliability of spatial distribution predictions. This study examines the impact of random errors in environmental factors on uncertainty in modeling and predicting species distributions. We first applied low-pass filtering to original environmental data to reduce random errors, while also introducing varying proportions of random noise to amplify error effects. Using presence-absence data of invasive species, we constructed multiple ISP models based on different machine learning algorithms. The case study in the Yangtze River Economic Belt, China, demonstrated that low-pass filtering effectively reduces random errors in environmental data of invasive species <i>Erigeron annuus</i>, thereby diminishing ISP uncertainty. Conversely, as the proportion of random errors increases from 5% to 20%, ISP uncertainty progressively escalates. Both the choice of machine learning models and the magnitude of random errors significantly influence ISP modeling outcomes. Furthermore, in the analysis of ISP interpretability uncertainty using the SHAP method that quantifies each environmental factor’s importance, it was observed that an increase in random errors causes deviations in environmental factor importance values and even changes in the dominant environmental factor. This research provides valuable insights for achieving more accurate and reliable predictions of potential geographical distributions of invasive species.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"19 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using retrospective travel behavior data from Shanghai across pre-crisis, acute, and normalized phases, the results show that users of private cars and non-motorized modes are more resilient, exhibiting a much lower propensity to shift away from their pre-crisis modes. In contrast, public transport users, particularly regular bus commuters, are more likely to experience persistent changes. Key determinants of these shifts include socio-economic characteristics, household composition, pre-crisis car ownership, and commute distance. The analysis further shows that the number of days working from home during the normalized phase significantly increases future willingness to work remotely, which in turn affects expected travel behavior. By explicitly distinguishing short-term adaptations from long-term behavioral change within the same cohort, this study contributes to a deeper understanding of how major public health crises can alter the co-evolution of human activity and the urban transport system, and provides evidence to support resilient, family-friendly, and multimodal transport policies.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"19 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding its variation across demographic groups is particularly important in mountainous cities, where terrain constrains mobility and shapes spatial development.

This study addresses this gap by integrating mobile phone signaling data with a nonlinear modelling framework to analyse travel distance across different age groups in Guiyang, a representative mountainous city in China. The results show significant age-based differences in travel distance, peak travel times and the effects of built environment, socioeconomic, and topographic factors. The effective service ranges of major activity centres vary across age groups, and several factors, including nighttime light intensity, distance to the central business district, and employment density, exhibit pronounced nonlinear and threshold effects on travel distance. Younger and middle-aged groups are more strongly associated with employment accessibility, whereas older adults are more closely related to population density. These findings contribute to a better understanding of age-differentiated travel behaviour in mountainous urban contexts and provide empirical support for more age-friendly urban planning and transport policies.</p></div>","PeriodicalId":46392,"journal":{"name":"Applied Spatial Analysis and Policy","volume":"19 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates how built environment inequality shapes the spatial structure of digital mobility networks, using dockless bike-sharing in Shenzhen as an empirical case. To capture complex nonlinear and spatially heterogeneous effects, we employ a hybrid analytical strategy integrating XGBoost-SHAP for feature importance and nonlinear interpretation, and Geographically Weighted Gaussian Process Regression for continuous spatial heterogeneity analysis. Our findings reveal that built environment inequality nonlinearly and spatially heterogeneously molds digital mobility networks. Inequalities in transport and service facilities emerge as dominant drivers, producing monotonic, threshold, and saturation effects that vary across network dimensions. Core urban areas experience amplified network intensity, connectivity, and destination diversity, while peripheral zones show attenuated or suppressive effects, reflecting a pronounced core-periphery gradient.

Drawing on multi-regional panel data from China spanning 2015–2022, this study develops a machine learning model with PM<sub>2.5</sub> concentrations as the outcome variable. By incorporating the Human Footprint Index (HF), alongside a suite of ecological, meteorological, and socio-economic variables, the analysis seeks to identify the associated mechanisms underlying pollution anomalies. The results indicate that: (1) at the global scale, the Human Footprint Index (HF) surpasses all natural and socio-economic variables, emerging as the primary determinant of PM<sub>2.5</sub> exposure; (2) the effect of HF exhibits pronounced regional heterogeneity, with a strong positive structure observed in Central and Northeastern China, while in the Eastern region the effect tends towards neutrality due to more favourable dispersion conditions and intensified governance, and although the overall contribution in the Western region remains relatively low; (3) the marginal pollution effect of HF demonstrates a nonlinear threshold pattern, appearing buffered or insensitive at low-intensity levels, but rising sharply in pollution risk once a critical threshold is exceeded. The findings suggest that the explanatory logic of air pollution is shifting towards a new paradigm centred on the Human Footprint. Accordingly, this study advocates the development of a pollution early-warning and governance framework that is sensitive to the intensity of human activity and grounded in the identification of spatial threshold effects.
