Causal Effects of Perceived False Alarm Ratio on Flood Protective Actions during Heavy Rain Warnings in Japan
Although the accuracy of weather forecasts and warnings has improved over time, the issue of false alarms is ongoing. Frequent false alarms can undermine public trust, potentially discouraging individuals from taking protective action in response to future forecasts and warnings. Understanding the causal effects of perceived false alarms on protective actions is thus critical. This study investigated the effect of the perceived false alarm ratio …
Modeling the Dynamics of Social Preparedness with Regional Interactions to Explore Efficient Flood Early Warning Systems
Flood early warning systems (FEWS) are essential in mitigating flood damage. To optimize their effectiveness, it is important to understand how people respond to warnings and prepare for flooding events. The key factors influencing social preparedness include 1) direct and 2) indirect experiences of floods and 3) trust in warnings. However, existing sociohydrological models do not incorporate all these elements. To include these elements for soci…
Household resilience realized by photovoltaic and battery energy system in natural hazard-triggered blackouts
Photovoltaic (PV) panels, increasingly popular due to decarbonization, are expected to increase household resilience during natural hazard-triggered blackouts. Their effectiveness is also expected to improve with the addition of storage batteries. However, PV ownership does not necessarily lead to electricity use in blackouts; even when used, the actual use of electrical appliances is unclear. We examined households that owned PV panels and exper…
Mosque as a Covid-19 vaccination site in collaboration with a private clinic
Ethnic minorities are vulnerable to disasters, including the COVID-19 pandemic. Vaccination strategies that do not leave ethnic minorities behind are required. This is a report on the use of Osaka Islamic Center, a mosque, as a group vaccination site for an ethnic minority group in Osaka, Japan, from August to September 2021. We aimed to discuss (1) the process of turning the mosque to a vaccination site, (2) the linguistic and religious consider…
Covid-19 vaccination at a mosque with multilingual and religious considerations for ethnic minorities
During a disaster, such as a pandemic, ethnic minorities tend to be left behind due to linguistic and religious differences. In the COVID-19 vaccination process, measures to include them are necessary, including the utilization of their resources and networks. The functions and challenges of such measures should be explored in real-world cases. We targeted a case in Ebina, Kanagawa, Japan, where a mosque, being a hub of foreign Muslims, was used …
Mosques in Japan responding to Covid-19 pandemic
Religious activities tend to be conducted in enclosed, crowded, and close-contact settings, which have a high potential of transmitting the coronavirus disease, 2019 (COVID-19); therefore, religious communities are expected to take appropriate infection prevention measures. Meanwhile, during past disasters, religious communities have provided various types of support to affected people; hence, their role in disaster risk reduction has received mu…
Designing the building space of a shopping street to use as a disaster evacuation shelter during the Covid-19 pandemic
Transition of post-disaster housing of rural households
To achieve post-disaster recovery of rural households in developing countries, it is necessary to understand the recovery conditions and the factors that play significant roles in the decision-making process. We aimed (1) to explain the transition of the residential status (i.e., type of places or houses in which affected households stay) after the disaster event and (2) to reveal the factors affecting the housing decisions. We interviewed 124 ru…
Potential of a shopping street to serve as a food distribution center and an evacuation shelter during disasters
This study demonstrates the potential use of a shopping street with disaster-proof buildings as a temporary evacuation shelter for local residents at the time of a disaster. We propose a simple estimation method to calculate the number of people for which the retail shops and restaurants in the shopping street can potentially provide food and drink using their inventory. We also estimate the number of evacuees that can be accommodated in the vaca…
Knowledge sharing, heterophily, and social network dynamics
This study formulates a model where (i) players are characterized by a knowledge set that changes endogenously by communication and (ii) some players have homophily preferences, while others have heterophily preferences. The study thus demonstrates that heterophilous players bridge different components and extend networks in an early stage and, subsequently, homophilous players take the role of a network hub that maintains network ties. It also i…
