The purpose of this paper is to connect the theoretical idea of warning systems as social processes with empirical data of people’s perceptions of and actions for warning for cyclones in Bangladesh.

A case study approach is used in two villages of Khulna district in southwest Bangladesh: Kalabogi and Kamarkhola. In total, 60 households in each village were surveyed with structured questionnaires regarding how they receive their cyclone warning information as well as their experiences of warnings for Cyclone Sidr in 2007 and Cyclone Aila in 2009.

People in the two villages had a high rate of receiving cyclone warnings and accepted them as being credible. They also experienced high impacts from the cyclones. Yet evacuation rates to cyclone shelters were low. They did not believe that significant cyclone damage would affect them and they also highlighted the difficulty of getting to cyclone shelters due to poor roads, leading them to prefer other evacuation options which were implemented if needed.

Theoretical constructs of warning systems, such as the First Mile and late warning, are rarely examined empirically according to people’s perceptions of warnings. The case study villages have not before been researched with respect to warning systems. The findings provide empirical evidence for long-established principles of warning systems as social processes, usually involving but not relying on technical components.

To investigate whether or not people at risk from the 26 December 2004 tsunamis could have had better warning of the event.

This paper examines short‐term actions related to warning following the earthquake and long‐term actions related to setting up an Indian Ocean tsunami warning system prior to the disaster. The evidence is presented in the context of the long‐term processes needed to create and maintain successful warning systems.

The evidence shows that, based on the knowledge and procedures existing at the time, any expectation of effective warning prior to the tsunamis was unreasonable. On 26 December 2004, as much action was taken as feasible. Prior to the catastrophe, the Indian Ocean tsunami risks were acknowledged but no warning systems were implemented because other priorities were deemed to be higher.

This paper presents a snapshot of the complex issue of warning system development and implementation. Each national and regional case study deserves detailed attention. Further work would add to a more complete understanding of conditions before 26 December 2004.

This case study provides a reminder that planning for warnings must be done before extreme events, not following them. Successful warning systems require investment in a long‐term, ongoing process involving pre‐event planning, education, and awareness.

This paper provides an initial attempt at evaluating Indian Ocean tsunami warnings on 26 December 2004.

Safety warnings remind construction workers about dangers and guide them to take necessary actions to avoid potential injuries, which could encourage their safe behavior. Workers’ behavior compliance with the safety warnings would be impacted by the risk perception levels induced by the warnings. This study aims to examine whether the design of safety warnings would impact the induced risk perception of workers

This study compared the risk perception levels of construction workers when processing two forms of safety warnings, i.e., safety signs and safety comics, which are commonly used in construction workplaces. Construction workers (n = 20) volunteered for an experiment with an implicit paradigm to probe how they perceive these safety warnings, using event-related potentials (ERPs) features collected by an electroencephalogram (EEG) sensor to indicate the risk perception level

The results demonstrated that the design of safety warnings would impact the induced risk perception. The safety signs and safety comics performed differently in inducing the workers’ risk perception. The safety signs representing prohibition and caution warnings induced significantly higher risk perception than the comics, and there were no significant differences regarding direction warnings

This is the first study to compare the risk perception levels between various forms of safety warnings presenting safety information in different ways. The findings would help to expand the knowledge of the relationship between the design of safety warnings and workers’ safety behavioral compliance

To survive and grow in an era of uncertainty, companies should strive not only for a single visionary view, which most likely corresponds with their expectations, but instead they should try to acquire multiple views that describe the whole ”window of opportunities”. The development of external market scenarios to assess current strategies is the usual way of coping with these uncertainties. Today this traditional scenario approach has to be extended in four directions: the use of market scenarios to systematically develop future‐robust strategies, the use of alternative strategy scenarios to address uncertainties within an organization, the use of scenarios as a basis for strategic early warning processes and the combination of performance measurement and strategic early warning in a scenario‐based future scorecard. In conclusion it is shown that scenarios could significantly help to bridge the gap between strategy implementation and early‐warning processes.

Even though Sri Lanka has established Early Warning (EW) mechanisms and Evacuation Procedures (EP) for the communities affected by the coastal disasters, there are several gaps, which hinder effective mechanisms in operation of disaster management practices. These gaps affect both the vulnerable communities and relevant authorities involved in the Disaster Management sector. This paper aims to identify and evaluate those gaps while providing adequate solutions.

For that, questionnaire surveys were carried out with a sample size of 217 via an online survey (117) among the urban level and interviews and telephone interviews (100) with the village level coastal communities. Data analysis was carried out using statistical analysis of questionnaire surveys and grounded theory was used for in-depth qualitative study.

Primary and secondary data obtained from the surveys were categorized under five themes, namely, response to early warning systems, evacuation routes, shelters, drills and training, effect of having a family vehicle, relatives and domestic animals, evacuation of people with special needs and cooperation with local government units. This paper analyses these themes in detail.

While critically evaluating the gaps in existing early warning mechanisms and evacuation procedures, this paper identifies correlations between some of the gaps and recommendations as well. Input from the international academics were also obtained at different forums and have strengthen the findings to overcome the barriers, which hinder successful mechanisms.

Persons with disabilities face the impacts of disasters differently. Early warning systems can be one of the powerful tools to reduce the vulnerabilities of persons with disabilities and mitigate the impacts of disasters. The main objective of this study was to assess the disability inclusiveness of the current early warning system (EWS) in flood-prone areas of Bangladesh.

A qualitative method was focused on getting in-depth information. Persons with disabilities participated in focus group discussions (FGDs) and shared the inclusiveness and gaps of the current EWS. Through extensive literature review, a checklist was developed to conduct the FGDs. QDA Miner 6.0.6 software was used for coding and analyzing the data.

Results indicated that, though persons with disabilities have proper risk knowledge, the current monitoring and warning service, dissemination and communication, and response capability are not fully inclusive. A significant gap in the EWS was found in response capability. Even if somehow persons with disabilities manage to receive a warning about a flood, they lack the capacity to respond to the warning.

The study proposed that to make an EWS inclusive and effective, the concerned authorities should focus on all four parts of the EWS.

Studies related to disability and disaster management are not very common. Conducting a qualitative study provided the persons with disabilities the opportunity to share their perspectives. Future studies can focus on vulnerability and capacity assessment of persons with disabilities to identify areas requiring interventions to enhance resilience.

This paper aims to provide a broad overview of the South Asian tsunami in relation to the development of the early warning system (EWS) as well as its integration within the seismic safety chain.

The paper focuses on social and administrative aspects that require detailed attention as key elements within the overall system. The observations grow from experience gained by Ian Davis from working on the UK IDNDR Flagship project Warnings and Forecasts from 1996‐9 and from participation in the Working Group advising Prime Minister, Tony Blair, on the development of warnings in preparation for the G8 meeting held in Scotland in June 2005.

The conclusions of the paper grow from variety of experiences that both the authors have gained in working for many years in the field of disaster management. A number of requirements emerge from the experience such as specific administrative measures, political will, scientific knowledge and the development of tsunami safety culture.

The paper provides an overview of some of the social and administrative measures needed to enable scientific warnings to be disseminated and applied at every level to protect people and their property.

The message of this paper is an attempt to stress the importance of the totality of an effective warning system. At present, the scientific side has secured vital attention. But this has to be complemented with the social and administrative elements on which all scientific detection depends. The authors argue that these neglected safety elements require urgent attention if a full safety system is to function effectively.

The current National Early Warning System for Sri Lanka (NEWS: SL) was established after the devastations of the Indian Ocean Tsunami in 2004. Although early warning (EW) systems and evacuation procedures are in place, several areas which need improvements have been emphasized in recent studies carried out in the country. Therefore, this paper aims to outline the gaps in existing EW and EP related to tsunami and other coastal hazards with a special focus on the use of social media for disaster communication based on age groups.

This study has drawn on a review of past studies carried out by the same research team to identify the scope of the study. In addition to that, a conceptual framework was developed for the use of social media in the event of a disaster. Based on this conceptual framework, an online questionnaire was administered to identify the current status of the use of social media in Sri Lanka during a disaster situation. In total, 408 responses were collected and analyzed using the binary logistic regression method to evaluate the variation of different predictors associated with the use of social media for disaster communication.

Findings of the study revealed that the use of social media for disaster communication depends on the previous experience of users and their age. The gender of users does not affect the use of social media for disaster communication. Therefore, the accuracy and timeliness of disaster information distributed via social media should be improved further to enhance the use of social media for disaster communication. Moreover, the findings have highlighted unaddressed issues in areas such as governance; communication of technical agencies; evacuation and shelters; and response of the community.

This paper has identified key areas that need attention in the process of enhancing the use of social media for disaster communication. More use of technological platforms such as social media for receiving disaster-related information can address issues such as bottlenecks in communication, poor awareness and lack of last-mile dissemination. Furthermore, this paper has proposed recommendations for addressing the identified gaps in the overall EW mechanisms and EP pertaining to tsunamis and other coastal hazards to enhance the coastal disaster resilience in Sri Lanka.

The role of a government investment project (GIP) management supervisor is to improve supervision performance and the Chinese government has issued a series of polices, displaying the determination to solve supervision problems. The purpose of this paper is to assist the government to play its role of supervisor and to realize progress supervision performance for GIP in practice with the Agent Construction System (ACS).

Taking consideration of the essence of ACS, the paper analyzes the system supported theory, which is a supervision mechanism, with contract management as the core and goals as orientation. The authors design the system frame and its composing modules according to the main function of this information system.

The research builds an expected supervision information system with four functional modules, which is designed according to logical sequence of supervision, based on a theoretical supervision mechanism.

The system is, to the best of the authors' knowledge, the most advanced and practical information system for GIP supervision published in the literature.
