The purpose of this study was to examine relationships among depression, psychological resilience, and other sociodemographic factors of individuals who were highly exposed to Hurricane Katrina in 2005 and the Deepwater Horizon Oil Spill in 2010. A spatially stratified random sample of 294 Mississippi Gulf Coast residents living in close proximity to the Gulf of Mexico were surveyed. Findings indicated that low education attainment, financial hardship, and disaster-related damages increased the likelihood of depression, whereas psychological resilience and having health insurance reduced the odds of depression. Implications for enhancing psychological resilience and increasing access to health insurance are discussed.

Although Twitter is used for emergency management activities, the relevance of tweets during a hazard event is still open to debate. In this study, six different computational (i.e. Natural Language Processing) and spatiotemporal analytical approaches were implemented to assess the relevance of risk information extracted from tweets obtained during the 2013 Colorado flood event. Primarily, tweets containing information about the flooding events and its impacts were analysed. Examination of the relationships between tweet volume and its content with precipitation amount, damage extent, and official reports revealed that relevant tweets provided information about the event and its impacts rather than any other risk information that public expects to receive via alert messages. However, only 14% of the geo-tagged tweets and only 0.06% of the total fire hose tweets were found to be relevant to the event. By providing insight into the quality of social media data and its usefulness to emergency management activities, this study contributes to the literature on quality of big data. Future research in this area would focus on assessing the reliability of relevant tweets for disaster related situational awareness.

As replicability and reproducibility (R&R) crises develop within emerging convergent inquiry, ethical use of provenance information is central to the establishment and preservation of trust in critical applications of GIScience and geospatial technologies. Today large volumes of geospatial data are generated at high velocity from satellite sensors and unmanned aircraft systems, citizen sensors, geolocation-based data services, global navigation satellite systems, and so on. The extensive use of these data for applications such as disaster and humanitarian response raises the issue of R&R from competing perspectives of location privacy and geospatial data quality. Although geospatial data can be integrated and linked with contextual information to identify individuals’ movements, steps taken to ensure privacy can complicate the multiuser development of high-quality geospatial workflows. Provenance information as digital records of historical (retrospective) and potential future (prospective) geospatial processes is often overlooked, misunderstood, or inadequately addressed. We explore the relationship between provenance information, location privacy, and geospatial data quality in the context of R&R with a focus on disaster analytics. We argue that in the era of big data and deep learning, GIScientists and associated institutions bear greater responsibility both for geospatial workflow quality and for location privacy. Given vastly heterogenous computational landscapes, we provide practical recommendations for ethically driven provenance and R&R research and development within the GIScience community and beyond.

This study examines the concept of electronic government (e-government) inclusiveness and evaluates the inclusiveness of local e-government websites. Inclusiveness sets e-government apart from other types of websites (e.g. commercial or organizational sites) that only serve exclusive market segments. An evaluation for inclusiveness of 101 local government websites from Mississippi (an underdeveloped area by many health and social metrics) revealed (1) a high frequency of issues that prevent inclusive service (on average each site had 291.83 issues), (2) high variability in terms of number of issues (range = [2, 3171]), and (3) widespread absence of websites (87 of the 188 municipalities and county seats did not have discoverable websites). These results suggest there is a need for more inclusiveness, but the allocation of resources to accomplish this may not be feasible. To address this, two strategic options are presented to information technology (IT) policy-makers who seek to leverage e-government for development: an idealistic approach with traditional IT investment for future returns and a pragmatic one that resembles an entrepreneurial IT start-up venture. The study contributes in three ways: we identify the concept and criteria of e-government inclusiveness; develop an automated, software-based, and replicable evaluation method that can be used by local governments to improve a website's inclusiveness; and present strategic options for using e-government to promote social and economic development.
