We frame adversities as “environmental shocks” to the entrepreneurial ecosystem using a disaster and emergency management and social work conceptual lens. Entrepreneurs subjected to these shocks then adopt resilience-building strategies as protective factors against future shocks, affording them the ability to bounce back or “bounce forward.” Using semi-structured interviews, we examined the types of adversities and resilience-building strategies employed by 27 Canadian entrepreneurs. Results indicated two forms of adversity and resilience-building—personal and professional— and the interplay within and between them. Personal and professional resilience included seeking therapy and financial preparedness while personal and professional adversity included isolation and problematic co‑leader relationships.

The factor weights in the AHP were established based on insights from expert evaluations, literature, and feedback from relevant public institutions. Flood susceptibility mapping effectiveness was assessed through the Receiver Operating Characteristic (ROC) curve, focusing on the Area under the Curve (AUC) metric.

A quantitative risk assessment model was developed by integrating the risk matrix and cloud model eigenvalues. The results show that risks are the most serious at municipal-level drills, with 20 risk factors (79.17 % of the total) at Level-III and above, decreasing at lower administrative levels (where risk level are categorized into Level-I (Major), Level-II (Large), Level-III (General), and Level-IV (Low) based on the risk matrix integrating likelihood and consequence levels, and Level-III and above risks may trigger resource wastage, drill failure, or even personnel casualties). Temporally, 39 risk factors at Level-III and above were concentrated in preparation stages across all administrative levels, declining to 3 such risk factors during rectification stage. Spatially, the number of risk factors peaked during the municipal-level and county-level preparation stages (11 risk factors respectively at Level-III and above), with their quantity gradually decreasing as the administrative level decreases and drill stages advance.

A survey was conducted of U.S.-based civil engineers specializing in flood infrastructure design to assess factors influencing their design-related judgments. Using various statistical analyses, this study identifies key predictors shaping engineers' engagement with risk and climate. Results show that engineers with liberal political orientations are more likely to incorporate climate change impacts into designs, and household income is negatively associated with risk-aversion attitudes. Engineers with limited work experience report more influence from peers, and dissatisfaction with engineering education is a strong predictor of reliance on personal attitudes when facing uncertainty.
