The Maritime Domain Awareness Center– A Human-Centered Design Approach, Gary Gomez Nov 2021

The Maritime Domain Awareness Center– A Human-Centered Design Approach, Gary Gomez

Political Science & Geography Faculty Publications

This paper contends that Maritime Domain Awareness Center (MDAC) design should be a holistic approach integrating established knowledge about human factors, decision making, cognitive tasks, complexity science, and human information interaction. The design effort should not be primarily a technology effort that focuses on computer screens, information feeds, display technologies, or user interfaces. The existence of a room with access to vast amounts of information and wall-to-wall video screens of ships, aircraft, weather data, and other regional information does not necessarily correlate to possessing situation awareness. Fundamental principles of human-centered information design should guide MDAC design and technology selection, and …


Recent Trends In Heat-Related Mortality In The United States: An Update Through 2018, Scott C. Sheridan, P. Grady Dixon, Adam J. Kalkstein, Michael J. Allen Jan 2021

Much research has shown a general decrease in the negative health response to extreme heat events in recent decades. With a society that is growing older, and a climate that is warming, whether this trend can continue is an open question. Using eight additional years of mortality data, we extend our previous research to explore trends in heat-related mortality across the United States. For the period 1975–2018, we examined the mortality associated with extreme-heat-event days across the 107 largest metropolitan areas. Mortality response was assessed over a cumulative 10-day lag period following events that were defined using thresholds of the …


Re-Spatializing Gangs: An Exponential Random Graph Model Of Twitter Data To Analyze The Geospatial Distribution Of Gang Member Connections, Ryan J. Roberts Jan 2021

Re-Spatializing Gangs: An Exponential Random Graph Model Of Twitter Data To Analyze The Geospatial Distribution Of Gang Member Connections, Ryan J. Roberts

Political Science & Geography Faculty Publications

Gang studies often use location-based approaches to explain gang members’ interconnectedness. Although this perspective remains consistent with the proximity principle that the smaller the geographic space, the greater the likelihood of observing connections between individuals, location-based studies limit our understanding of gang member connections to narrowly defined geographic spaces at specific points in time. The advent of social media has re-spatialized gang member interconnectedness to unbounded geographic spaces, where the preservation of online activity can extend indefinitely. Despite having an online presence, most research examining the digital footprint of gangs tends to be descriptive. This study collects Twitter data to …


A Global Ecological Classification Of Coastal Segment Units To Complement Marine Biodiversity Observation Network Assessments, Roger Sayre, Kevin Butler, Keith Van Graafeiland, Sean Breyer, Dawn Wright, Charlie Frye, Deniz Karagulle, Madeline Martin, Jill Cress, Tom Allen, Rebecca J.

A new data layer provides Coastal and Marine Ecological Classification Standard (CMECS) labels for global coastal segments at 1 km or shorter resolution. These characteristics are summarized for six US Marine Biodiversity Observation Network (MBON) sites and one MBON Pole to Pole of the Americas site in Argentina. The global coastlines CMECS classifications were produced from a partitioning of a 30 m Landsat-derived shoreline vector that was segmented into 4 million 1 km or shorter segments. Each segment was attributed with values from 10 variables that represent the ecological settings in which the coastline occurs, including properties of the adjacent …

This study evaluates the spatial-temporal patterns in Virginia tornadoes using the National Weather Service Storm Prediction Center’s Severe Weather GIS (SVRGIS) database. In addition to descriptive statistics, the analysis employs Kernel Density Estimation for spatial pattern analysis and space-time cubes to visualize the spatiotemporal frequency of tornadoes and potential trends. Most of the 726 tornadoes between 1960–2019 occurred in Eastern Virginia, along the Piedmont and Coastal Plain. Consistent with other literature, both the number of tornadoes and the tornado days have increased in Virginia. While 80% of the tornadoes occurred during the warm season, tornadoes did occur during each month …


The Relationship Between Neighborhood Characteristics And Homicide In Karachi, Pakistan, Salma Hamza, Imran Khan, Linlin Lu, Hua Liu, Farkhunda Burke, Syed Nawaz-Ul-Huda, Muhammad Fahad Baqa, Aqil Tariq Jan 2021

The geographical concentration of criminal violence is closely associated with the social, demographic, and economic structural characteristics of neighborhoods. However, few studies have investigated homicide patterns and their relationships with neighborhoods in South Asian cities. In this study, the spatial and temporal patterns of homicide incidences in Karachi from 2009 to 2018 were analyzed using the local indicators of spatial association (LISA) method. Generalized linear modeling (GLM) and geographically weighted Poisson regression (GWPR) methods were implemented to examine the relationship between influential factors and the number of homicides during the 2009–2018 period. The results demonstrate that the homicide hotspot or …


Nonprofit Capacity To Manage Hurricane-Pandemic Threat: Local And National Perspectives On Resilience During Covid-19, Nicole S. Hutton, Steven W. Mumford, Marina Saitgalina, Juita-Elena (Wie) Yusuf, Joshua G. Behr, Rafael Diaz, John J. Kiefer Jan 2021

This paper examines nonprofits' capacity for responding to simultaneous hurricane-pandemic threat, addressing: (1) strategies nonprofits use to deliver services during the COVID-19 pandemic, and (2) how natural hazards may affect nonprofit roles in emergency service delivery during a pandemic. Data come from a survey of New Orleans-based nonprofits demonstrating effects of pandemic on local nonprofit service delivery, and workshops with U.S. coastal community stakeholders exploring expectations for nonprofit roles in emergency operations nationwide. Nonprofits have applied resilient strategies including virtual operations, staff reductions, and funding diversification, but vulnerabilities remain. Findings guide a research agenda for building nonprofit and community resilience.
