From influence to action
This study examines the self-impact of online opinion leadership on pro-environmental behavior (PEB) within Chinese social media, highlighting the mediating roles of perceived benefits and costs. While traditional perspectives often emphasize the persuasive influence of opinion leaders on others, this research underscores how assuming an opinion leadership role can shape individuals’ own behaviors. Drawing on social exchange theory, we propose th…

Money Versus Time
The development of social media platforms has ushered in a new era in which online media interactions, such as Facebook and Twitter, have largely supplanted traditional means of interpersonal interaction. This has resulted in problems such as cyberbullying and social exclusion. Previous research has indicated that people who feel socially excluded react more positively to altruistic behaviors, which could effectively restore connection and happin…
The Golden Mean
Zhongyong (golden mean) is a typical Oriental Confucius thought that addresses interpersonal harmony and interdependence. A moderated mediating model was used in this study to examine the relationship between Zhongyong and environmental behavior. The results of our model showed that Zhongyong was positively associated with environmental behavior. In comparison to people with lower levels of Zhongyong, respondents with higher levels of Zhongyong h…
Mind the Gap
This study proposes a moderated serial mediation model to examine the paths and conditions by which authoritative media use and social media use promote public and private pro-environmental behaviours (PEBs). By employing the norm activation theory and through a nationwide survey in China, the study finds that both authoritative media use and social media use can indirectly contribute to both public and private PEBs first by increasing perceived …
D Change Detection Using Adaptive Thresholds Based on Local Point Cloud Density
In recent years, because of highly developed LiDAR (Light Detection and Ranging) technologies, there has been increasing demand for 3D change detection in urban monitoring, urban model updating, and disaster assessment. In order to improve the effectiveness of 3D change detection based on point clouds, an approach for 3D change detection using point-based comparison is presented in this paper. To avoid density variation in point clouds, adaptive …
An Economic Development Evaluation Based on the OpenStreetMap Road Network Density
The evaluation of urban economies has been one key concern identified by scholars. In the past, most research methods on urban development assessments have been based on statistical data, and the analysis results have been presented in the form of statistical tables. Moreover, the development of urban road networks reflects the status of urban development and spatial metrics, which are obtained from the urban road network which can be used to eva…
A Vector Line Simplification Algorithm Based on the Douglas–Peucker Algorithm, Monotonic Chains and Dichotomy
When using the traditional Douglas–Peucker (D–P) algorithm to simplify linear objects, it is easy to generate results containing self-intersecting errors, thus affecting the application of the D–P algorithm. To solve the problem of self-intersection, a new vector line simplification algorithm based on the D–P algorithm, monotonic chains and dichotomy, is proposed in this paper. First, the traditional D–P algorithm is used to simplify the original…
Damage Signature Generation of Revetment Surface along Urban Rivers Using UAV-Based Mapping
The all-embracing inspection of geometry structures of revetments along urban rivers using the conventional field visual inspection is technically complex and time-consuming. In this study, an approach using dense point clouds derived from low-cost unmanned aerial vehicle (UAV) photogrammetry is proposed to automatically and efficiently recognize the signatures of revetment damage. To quickly and accurately recover the finely detailed surface of …
