Any Port In A Storm: Vessel Activity And The Risk Of Iuu-Caught Fish Passing Through The World’S Most Important Fishing Ports, Gilles Hosch, Bradley Soule, Max Schofield, Trevor Thomas, Charles Kilgour, Tim Huntington
Journal of Ocean and Coastal Economics
This study assesses the risk of fish from illegal, unregulated and unreported (IUU) sources passing through the world’s most important fishing ports and explores the drivers of this risk.
Like previous studies it has attempted to rank ports and States based on landings and vessel visits reported by governments by using Automatic Identification System (AIS) positional data transmitted by fishing and fish carrier vessels to identify the locations of ports and rank them based on the frequency of visits by foreign-flagged and domestic-flagged vessels. It advances our thinking in that (i) the analysis includes an estimation of the hold ...

Open Access Articles
INTRODUCTION: Opioid overdose deaths quintupled in Massachusetts between 2000 and 2016. Potentially inappropriate opioid prescribing practices (PIP) are associated with increases in overdoses. The purpose of this study was to conduct spatial epidemiological analyses of novel comprehensively linked data to identify overdose and PIP hotspots.
METHODS: Sixteen administrative datasets, including prescription monitoring, medical claims, vital statistics, and medical examiner data, covering >98% of Massachusetts residents between 2011-2015, were linked in 2017 to better investigate the opioid epidemic. PIP was defined by six measures: > /=100 morphine milligram equivalents (MMEs), co-prescription of benzodiazepines and opioids, cash purchases of opioid prescriptions, opioid prescriptions ...
Determining The Effect Of Mission Design And Point Cloud Filtering On The Quality And Accuracy Of Sfm Photogrammetric Products Derived From Suas Imagery, Daniel Shay Hostens
MSU Graduate Theses
This research investigates the influence that various flight plan and mission design strategies for collecting small unmanned aerial system (sUAS) imagery have on the accuracy of the resulting three-dimensional models to find an optimal method to achieve a result. This research also explores the effect that using gradual selection to reduce the sparse point cloud has on product accuracy and processing details. Imagery was collected in the spring of 2018 during leaf-off conditions at six field sites along the North Fork of the White River. The aerial imagery was collected using a DJI Phantom Pro 4 sUAS. Four different image ...
Greenway Trail Viewshed Characteristics: Planning Applications Using Gis And Remote Sensing, 2019 Missouri State University
Greenway Trail Viewshed Characteristics: Planning Applications Using Gis And Remote Sensing, Aric Addison Beehler
MSU Graduate Theses
This study applies theoretical findings relating greenway trail viewshed characteristics to a proposed greenway trail. Utilizing geographic information systems and remote sensing techniques, this study compares the viewshed characteristics of two proposed routes to connect an existent greenway trail system to Wilson’s Creek National Battlefield in Greene County, MO. Light Detection and Ranging data is then used to map the viewshed of each route and calculate the openness and interconnectedness of each viewshed. High-resolution multispectral imagery is then used to calculate the Normalized Difference Vegetation Index measuring the “greenness” within each viewshed. Finally, parcel-level land use data is used ...
An Evaluation Of The Impact Of Leading Pedestrian Interval Signals In Nyc, 2019 CUNY Hunter College
An Evaluation Of The Impact Of Leading Pedestrian Interval Signals In Nyc, Jeremy J. Sze
School of Arts & Sciences Theses
I evaluated the impact of the phased introduction of Leading Pedestrian Interval Signals (LPIs) on collision and injury outcomes at 12,987 signalized traffic intersections in New York City over the course of 25 quarters from 2012 to 2018. An intersection is treated when a LPIs is installed to give pedestrians lead time to cross the street before vehicles are allowed to move. Outcomes from NYPD’s Motor Vehicle Collisions data were matched to signalized intersections. I hypothesize that LPIs would reduce collisions and reduce injuries for pedestrians at intersections. A difference in difference fixed effects panel regression was used ...
Using Historic Glo Data And Gis To Assess The Potential For Local Bison Bison Near Two Wisconsin Late Prehistoric Oneota Localities, 2019 University of Wisconsin-Milwaukee
Using Historic Glo Data And Gis To Assess The Potential For Local Bison Bison Near Two Wisconsin Late Prehistoric Oneota Localities, Andrew Michael Saleh
Theses and Dissertations
Bison (Bison bison) remains are rare in the archaeological record of Wisconsin. This thesis uses a Geographic Information System (GIS) to better understand native vegetation near sites with reported bison bone to assess their ecological viability to support local bison herds. The distribution of bison bone recovered in archaeological contexts in Wisconsin can be summarized as follows: few sites report bison remains, the archaeological contexts that do report bison are clustered in a few Late Prehistoric period locations (approximately A.D. 1300-1650), and bison remains are rare in comparison to other fauna at those sites (Arzigian et al. 1989; Boszhardt ...

Homelessness In Portland, Oregon: An Analysis Of Homeless Campsite Spatial Patterns And Spatial Relationships, Krystle N. Harrell
Geography Masters Research Papers
Homelessness is a complex American social issue. Understanding the homeless population, including how many people experience homelessness, how they entered the experience, their demographics, how they survive, and where they survive, aids policymakers, planners, and advocates in developing the appropriate approaches and solutions to end and prevent homelessness. Analysis of homeless spatial patterns and distributions across different locales provides a more in-depth understandings of this population and how best to support them, from the local to national level. Using geographic information systems (GIS) and statistical methods, this study examines the spatial patterns of homeless campsites and their relationship with urban ...
Anthropogenic Landscapes Of Amazonia : A Spatial Analysis Of Landscape Modification And Settlement Organization At Macurany, Brazil., M. Grace Ellis
Electronic Theses and Dissertations
Anthropogenic landscapes are the product of complex human-environment processes that form distinct features in the landscape, which materially preserve and reflect human behavior. Anthropogenic landscapes in Amazonia likely date back to human colonization of the region around 16,000 BP. Since colonization, humans have been marking, modifying, managing, and engineering the landscape resulting in a mosaic of anthropogenic landscape features across Amazonia. The diversity of ancient landscapes documented in Amazonia reflects the cultural heterogeneity that existed in the past. This research explores the complex human-environmental processes that form distinct, identifiable, lasting features on the landscape and what these features can ...

We introduce Project Sidewalk, a new web-based tool that enables online crowdworkers to remotely label pedestrian-related accessibility problems by virtually walking through city streets in Google Street View. To train, engage, and sustain users, we apply basic game design principles such as interactive onboarding, mission-based tasks, and progress dashboards. In an 18-month deployment study, 797 online users contributed 205,385 labels and audited 2,941 miles of Washington DC streets. We compare behavioral and labeling quality differences between paid crowdworkers and volunteers, investigate the effects of label type, label severity, and majority vote on accuracy, and analyze common labeling errors ...
The Image From The Road: Towards Mapping The Phenomenological, 2019 University of Arkansas, Fayetteville
The Image From The Road: Towards Mapping The Phenomenological, Rachel Anna Smith Loerts
Theses and Dissertations
An area of focus, used in early and contemporary forms of cognitive geography research, is the ‘cognitive map’, a concept that suggests “that people hold a map-like database in their minds to which they can add and use to tackle geographical tasks”. Kevin Lynch, an urban planner in the 1960s, was an early adopter of the cognitive map approach to reveal spatial cognition, what or how people see their environment, specifically cognition of the urban environment. Lynch’s research aimed to develop empirical methods, to identify how people make spatial relationships. Contemporary tools like machine learning are now considered relevant ...

Identifying Priority And “Bright-Spot” Counties For Diabetes Preventive Care In Appalachia: An Exploratory Analysis, Peter J. Mallow, Michael Topmiller, Jennifer Rankin, Jene Grandmont, David Grolling, Jessica L. Mccann, Mark Carrozza
Journal of Appalachian Health
Introduction: Type 2 diabetes mellitus (T2DM) prevalence and mortality in Appalachian counties is substantially higher when compared to non-Appalachian counties, although there is significant variation within Appalachia.
Purpose: The objectives of this research were to identify low-performing (priority) and high-performing (bright spot) counties with respect to improving T2DM preventive care.
Methods: Using data from the Centers for Medicare and Medicaid (CMS), the Dartmouth Atlas of Health Care, and the Appalachia Regional Commission, conditional maps were created using county-level estimates for T2DM prevalence, mortality, and annual hemoglobin A1c (HbA1c) testing rates. Priority counties were identified using the following criteria: top 33rd ...
Identifying Populations At Greater Risk Of Malaria Due To Hydroelectric Dams In Ethiopia: A Case Study Of The Gilgel Gibe Iii Hydroelectric Dam, Abigail Smith
Scholars Week 2019
"Malaria is a communicable disease that is spread by female mosquitos of the Anopheles genus. It is acutely prevalent in Sub-Saharan Africa, where 90% of malaria deaths occur each year. One Sub-Saharan African country historically impacted by malaria is Ethiopia. In the past twenty years, malaria prevalence has been significantly decreased throughout Sub-Saharan Africa; yet, anthropogenic environmental changes are changing the landscape of malaria. Scholarly literature has cited a positive relationship between hydroelectric dams and malaria in Sub-Saharan Africa. Ethiopia is currently expanding their hydroelectric infrastructure.
The Gilgel Gibe III hydroelectric dam is located on the Omo River in Southwestern ...

Mapping And Gis Tools For Disaster Preparation And Recovery, Jim Craner
There are many tools for online and offline mapping, as well as geographic information systems ("GIS"), that public librarians can offer their communities. These tools can be invaluable for emergency response planning before a disaster as well as response and recovery operations after a disaster. Librarians, as community information and technology stewards, can play a valuable role in these scenarios.
Understanding Small Town Sprawl Using Gis, 2019 University of North Alabama
Understanding Small Town Sprawl Using Gis, Pricilla Lema
Scholars Week 2019
Unmitigated effects of sprawl in many small rural towns have been documented. The common thread in the literature identifies the negative externalities of sprawl, especially the consumptive and inefficient nature of land use. Some of the most commonly cited sprawl mitigation strategies include revitalization of downtowns, investing in public transportation, and infill development among others. However, little attention has been given to repurposing of brownfields into usable space as a sprawl mitigation strategy. This study examines, first, how analytical GIS tools can help in the assessment of small town sprawl; and second, to identify city space designated as brownfields for ...

Show Your Stripes Research and Creative Showcase
The project I would like to present is the GIS project I did for Dr. Boston on the Don Carlos archaeology site in Moniteau County, Missouri. The presentation would consist of a few aerial photos of the site, as well as a plat map from the 1930s, and a topographic map from around the mid-1980s; all of which have a GIS’d outline of individual parts of the site. I will then explain the items used to map the entire site, as well as some of the items that were discovered, why they are of important to the site and ...
Geographical Analysis Of Offender Vulnerability: Modeling Coastal Hazards And Social Disorganization In Southern Mississippi, 2019 The University of Southern Mississippi
Geographical Analysis Of Offender Vulnerability: Modeling Coastal Hazards And Social Disorganization In Southern Mississippi, Ashleigh N. Price
Hazards research continually examines how specific groups are affected by damaging events and how their unique sociodemographic characteristics contribute to variations in resilience and recovery. Studies have shown that underprivileged communities suffer more adversely and take longer to recover from hazard events. Probationers and parolees are uniquely disadvantaged regarding demographics and economic opportunity, both of which contribute to increased vulnerability and reduced resilience. Numerous legal restrictions and widespread discrimination towards former criminals means offenders are often relegated to underserved, criminogenic neighborhoods. Given such severe social and financial limitations, offenders have little capacity to prepare for or recover from disasters.
Calculating A Drought Vulnerability Index For South Africa Based On Social And Biophysical Characteristics, Mollie Gaines
Undergraduate Honors Theses
Using census data from the 2011 South African census and precipitation data from the National Oceanic and Atmospheric Association (NOAA), a multicriteria index ranking the relative climate vulnerability to drought of areas in South Africa was created. The index was developed by aggregating social characteristics into a Social Vulnerability Index (SoVI) using a principle components analysis (PCA), and aggregating biophysical characteristics into a standardized precipitation index (SPI) representative of drought risk. These separate indices were then aggregated using a Pareto Rank Order to determine the overall vulnerability of areas relative to other areas in the country. The resulting index was ...
An Evaluation Of Sentinel-1 And Sentinel-2 For Land Cover Classification, 2019 Clark University
An Evaluation Of Sentinel-1 And Sentinel-2 For Land Cover Classification, Aaron Meneghini
International Development, Community and Environment (IDCE)
This study evaluates Sentinel-1 and Sentinel-2 remotely sensed images for tropical land cover classification. The dual polarized Sentinel-1 VV and VH backscatter images and four 10-meter multispectral bands of Sentinel-2 were used to create six land cover classification images across two study areas along the border of the Bolivian Pando Department and the Brazilian state of Acre. Results indicate that Sentinel-2 multispectral bands possess a higher overall performance in delineating land cover types than the Sentinel-1 backscatter bands. Sentinel-1 backscatter bands delineated land cover types based on their surficial properties but did not facilitate the separation of similarly textured classes ...
