{"title":"The Role of Social Media in Disaster Recovery Following Hurricane Harvey","authors":"Courtney Page-Tan","doi":"10.1515/jhsem-2018-0054","DOIUrl":"https://doi.org/10.1515/jhsem-2018-0054","url":null,"abstract":"Abstract Hurricane Harvey was social media's first real stress test as a disaster response and recovery mechanism. A confluence of conditions makes it an ideal case study of social media's role in disaster recovery: the lack of a government-issued evacuation order, a call from government leadership for willing and able volunteers with a boat or high-water vehicle to perform life-saving rescues, and wide-spread adoption of social media platforms in the Houston area. While research on online social networks and disasters continues to grow, social scientists know little about how these online networks transform during a crisis and, further, how they drive disaster outcomes. With two original datasets, this study investigates how Houston's online social network transformed during Hurricane Harvey (2017), and the relationship between social media activity and post-Harvey recovery. The findings of a social network analysis (N= 2,387,610) and subsequent statistical analyses reveal the Houston-area online social network grew denser, clustered, and more efficient during the disaster. A spatial analysis and three separate regression models of activity before, during, and after Hurricane Harvey reveal that among 333 Nextdoor Neighborhoods, hyperlocal social media activity was a statistically significant predictor of the rate of rebuilding in these geographically based online communities. These findings suggest that policy and decision-makers should invest into online and offline hyperlocal social networks well before a disaster strikes, and leverage resources and legislation to maintain and strengthen the telecommunications and energy infrastructure that supports access to social media and telecommunications infrastructure during a time of crisis.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79597474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this, the United States Centers for Disease Control and Prevention (CDC) focused on strengthening training, personnel database systems, and responder outreach. To ensure availability of well-trained public health emergency responders, CDC and external partners coordinated training, planning, exercise, and evaluation activities; established the School of Preparedness and Emergency Response; and implemented Responder Training Tiers for response roles with defined functional competencies. For personnel information, CDC developed interoperable databases to streamline the search for specific staff expertise for a response. To improve responder outreach, CDC developed various mechanisms to efficiently identify and assign potential responders to responses. These measures work together to sustain a qualified workforce for public health emergencies, and may be helpful to other public health agencies for staffing and training of their response workforce.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88173262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An emergency response is mission- and time-critical, unstructured, very dynamic, and it is very difficult to predefine or even to anticipate all possible response scenarios. Therefore, designing and implementing a software system to support such a response system is highly complicated and challenging. This research aims to investigate and discuss how Adaptive Case Management (ACM) can be leveraged in the design and implementation of a case-based emergency response system. In particular, this research considers the best practices of the National Incident Management System (NIMS), which is an essential part of the National Response Framework (NRF) developed in the United States. As a proof-of-concept, a prototype demonstration has been carried out on a leading commercial ACM platform. In addition, a walkthrough scenario is discussed to elaborate how ACM can support emergency response activities in real settings using the Incident Command System (ICS) organizational structure. The key benefit of this research is to guide the development and implementation of cased-based emergency response systems with a flexible and agile approach.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89540609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether graduates are employable, whether they are getting jobs, and why some get jobs and others do not have been of concern. Yet, until recently, no empirical study had examined the extent to which emergency management degree holders who want emergency management jobs actually get them. Jensen and Kirkpatrick (2020), found that the majority of graduates who intended such jobs got them, while almost a third did not. Jensen and Kirkpatrick (2019), proposed a theoretical framework that might guide research on job outcomes of emergency management degree program graduates, including job placement. This manuscript reports the authors' efforts to utilize the theoretical framework to explore the difference between those graduates who wanted and secured an emergency management position post-graduation and those who wanted one but did not. Specifically, this manuscript reports initial findings and challenges related to this question in the context of a theoretical framework of job placement and the current state of emergency management higher education nationally.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88979062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective communication is a critical resource that can significantly enhance public safety. A mass notification system (MNS) uses text messaging to inform constituents of crisis, provide recommendations, connect to resources, and has the advantage of speed. Limited research has been conducted on the variables that influence the effectiveness, utilization, and perceptions of MNS. The extant study employs a multi-method approach to advance the scholarly knowledge on MNS. All emergency managers in a state were surveyed on issues of MNS enrollment, utilization, and brand. A subgroup of emergency managers were then interviewed to provide depth to the survey findings. Key findings indicate wide variability in MNS usage, little relationship between population size and enrollment, and a high perceived importance of MNS as a communication modality. Policy implications and recommendations are offered.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89190408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article explores how agencies use social networking applications and microblogs such as Twitter and Facebook to share information and interact with each other. Public information officers (PIOs) from 35 state emergency management agencies were interviewed, and transcripts were analyzed using a grounded theory approach. Findings demonstrate that PIOs employ Twitter and Facebook to monitor content for situational awareness, post training opportunities, network with other agencies, and share and reuse content in different ways. Fewer agencies directly coordinate preparedness information campaigns during nonthreat periods and risk communication during emergency response operations. General impediments to those practices include lack of personnel, insufficient technical knowledge, and preferences for other channels. In all, Twitter and Facebook complement—but do not take the place of—other information and communications technology (ICTs) that facilitate operational coordination.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82661985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Government agencies have made efforts in improving the nation’s disaster response framework to minimize fatalities and economic loss due to disasters. Disaster response has evolved with the emergency management agencies incorporating systematic changes in their organization and emergency response functions to accommodate lessons learned from past disaster events. Technological advancements in disaster response have also improved the agencies’ ability to prepare for and respond to natural hazards. The transportation and logistics sector has a primary role in emergency response during and after disasters. In this light, this paper seeks to identify how effective policy changes and new technology have aided the transportation and logistics sector in emergency response and identify gaps in current practices for further improvement. Specifically, this study compares and contrasts the transportation and logistical support to emergency relief efforts during and after two major Hurricane events in the U.S., namely Hurricane Katrina (which affected New Orleans in 2005) and Hurricane Harvey (which affected Houston in 2017). This comparison intends to outline the major steps taken by the government and the private entities in the transportation and logistics sector to facilitate emergency response and the issues faced during the process. Finally, the paper summarizes the lessons learned from both the Hurricane events and provides recommendations for further improvements in transportation and logistical support to disaster response.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75124161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Responses to a 2016 survey described beneficial and detracting features of the federal requirements, which affected the department's ability to meet their jurisdiction's demands. This article describes these attitudes and determines whether jurisdictions that were favorable to or against policy changes made during Obama's administration represent jurisdictions that voted Democratic or Republican in the five previous presidential elections. Doing so tests the theory of \"representative bureaucracy\", which suggests local bureaucrats will represent their constituents' background and beliefs in their actions or attitudes. The findings suggest that elements of \"representative bureaucracy\" exist, but also that disappointment over the actions taken by both administrations persist.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85292822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes have a considerable influence on the development of CBRN defense technologies: from highly predictable scenarios with relatively good risk assessment and intelligence capabilities, to a wide variety of scenarios with limited predictive capabilities in the case of terrorism. First responders are challenged to deal with multilateral issues, which are more complex than ever before. As long as the threat was state-posed and in a war context, CBRN technologies were developed in light of defense authorities’ demands. Nowadays, with the diminishing wartime threat, the market is left “unsupervised.” Manufacturers and developers are adopting their technologies with limited to no feedback and support of the end-users. In turn, this leads to suboptimal technological results from the operational point-of-view. This paper calls for a multi-sectorial, joint venture between academia, industry, government and first responders. Such collaboration should seek a non-competitive, financially stable environment to bridge gaps in the development of defense technologies that are adapted to the rapidly changing threats. Examples and discussion will be provided.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82704907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With active engagement from CDC leadership, 266 scientific and support staff from across the agency participated in the Gotham Shield exercise. The scenario involved a 10-kiloton detonation near the Lincoln Tunnel in New Jersey. This nuclear detonation scenario provided CDC with the opportunity to test some of the all-hazards tools the agency uses during response to other national or international emergencies, such as Geographic Information Systems (GIS) and mapping tools, and apply these tools to a nuclear emergency. Geospatial analysis associated with real time data can provide near real time information for individuals and entities associated with response and recovery activities. This type of analysis can provide timely data in regard to maps and information used to properly place staging areas for Community Reception Centers (CRC), mass care locations, and other medical care and countermeasure related services. Maps showing locations of power loss, such as locations of lost or inoperable main electrical grid and substations, combined with real time data on where power is available provides valuable information for first responders and emergency managers as well as responders engaged in communicating critical public messages to affected populations in these areas. By using real-time information, response officials can direct the response, allocate scarce resources, aid in coordination efforts, and provide a more efficient means of providing critical public health and medical services. The results of the exercise highlight the importance of using geospatial analysis for response planning and effect mitigation before, during, and after a public health event of this magnitude, and the value they represent in informed decision making.","PeriodicalId":46847,"journal":{"name":"Journal of Homeland Security and Emergency Management","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89647236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
