Evolutionary game analysis of opportunistic behavior of Sponge City PPP projects: a perceived value perspective

“…), which have seriously restricted the sustainable development of urban ecology 1 , 2 and have received increasingly worldwide concern 3 , 4 . Under the background of global climate change, extreme events such as extreme high temperature, extreme precipitation and floods will occur more frequently in cities in the future, which puts forward higher requirements for the resilience of urban water system 5 . In China, in order to solve urban water problems, Chinese President Xi Jinping emphasized the construction of Sponge City (SC) Program (Fig.…”

Pre-rainy Season Rainstorms in South China—Risk Perception of the 11 April 2019 Rainstorm in Shenzhen City

“…In this study, we used a two-factor model of risk perception-the possibility of encountering rainstorms/suffering losses and the degree of threat, that is, the perceived occurrence probability of rainstorm disasters and their threat level and consequences (Liu et al 2006) to measure the level of public risk perception of rainstorm disasters in Shenzhen in the pre-rainy season. For data collection, we designed a questionnaire that considered knowledge, attitude, trust, and practice (Dai 2014;Ridha et al 2022). Table 1 presents the four dimensions of our questionnaire survey: level of risk perception, knowledge of risk, impact of the 11 April 2019 (4•11 hereafter) rainstorm on public risk perception, and degree of trust in the government.…”

“…We selected 50 respondents and circulated the questionnaire to them. We adopted the Cronbach coefficient to test the reliability of the 16 questions (Zhou 2017; Ridha et al 2022), and all the results obtained are higher than 0.7, indicating that the questionnaire has good reliability (Table 2). We also used KMO (Kaiser-Meyer-Olkin) & Bartlett value to test the validity of these questions (Chung et al 2004).…”

Emergence of Urban Heat Traps from the Intersection of Human Mobility and Heat Hazard Exposure in Cities

“…Human mobility datasets have been widely used in multiple hazards, including hurricane , Rajput et al, 2020, Dargin et al, 2021, Paradkar et al, 2022, flooding (Esparza et al, 2022, Farahmand et al, 2022a, Farahmand et al, 2022b, Ridha et al, 2022, Yuan et al, 2022a, Yuan et al, 2022b, and infectious diseases (Fan et al, 2021, Ma et al, 2022, Li et al, 2021, Rajput et al, 2022. These studies have found human mobility data was useful to understand people's reaction to hazards (Lai et al, 2019).…”
