Adoption Statistics Analysis Using Geographic Information Systems, Ashtan H. Williams

Scholars Week

This project highlights the use of Geographic Information Systems (GIS) for non-locational data by displaying adoption statistics. All topics displayed according to a political boundary (state or country) to include percentage of population awaiting adoption, time from termination of parental rights to finalization of adoption. A GIS-based analysis conducted for this project compares the cost of adoption from within the United States international. There is a focus on types of adoptions like special needs and race specific to provide an overall understanding of adoption in hopes to raise awareness.

Global climate change (GCC) is projected to bring higher-intensity precipitation and higher-variability temperature regimes to the Northeastern United States. The interactive effects of GCC with anthropogenic land use and land cover changes (LULCCs) are unknown for watershed level hydrological dynamics and nutrient fluxes to freshwater lakes. Increased nutrient fluxes can promote harmful algal blooms, also exacerbated by warmer water temperatures due to GCC. To address the complex interactions of climate, land and humans, we developed a cascading integrated assessment model to test the impacts of GCC and LULCC on the hydrological regime, water temperature, water quality, bloom duration and severity …

Constituting Agricultural And Food Policy In Malawi: The Role Of The State And International Donors In The Farm Input Subsidy Program (Fisp), Peter Rock Nkhoma

USF Tampa Graduate Theses and Dissertations

Numerous studies have been undertaken on the political economy of agricultural policies in developing countries. These studies have explained agricultural policies in terms of urban bias, economic reforms, and domestic politics. Recently, the emphasis has been on explanations that reference the existence of a rational-legal and patronage element within the African state. Such explanations tend to underplay the extent to which agricultural policies are devised in a context of power asymmetries between the state and international donors or financial institutions. In the Malawian context specifically, limited attention has been paid to the possibility that policies are a negotiated outcome of …

Poland’S Voivodeships And Poviats And The Geographies Of Knowledge: Addressing Uneven Human Resources, Stanley D. Brunn, Marcin Semczuk, Rafał Koszek, Karolina Gołuszka, Gabriela Bołoz

Geography Faculty Publications

In a postindustrial economic world, information economies are key components in local, regional and national development. These are service economies, built on the production, consumption and dissemination of information, including education, health care, outsourcing, tourism, sustainability and related human welfare services. We explore the geography/knowledge intersections in Poland’s voivodeships and poviats by using the volumes of information or hyperlinks about selected information economies. Google hyperlinks are electronic knowledge data that can be mapped to highlight the areas of most and least information about certain subject categories. While some mapping results are expected, such as Warsaw and Krakow, being prominent, in …

The Economics Of Adaptation To Climate Change In Coasts And Oceans: Literature Review, Policy Implications And Research Agenda, Charles S. Colgan

Journal of Ocean and Coastal Economics

Sea level rise and other effects of climate change on oceans and coasts around the world are major reasons to halt the emissions of greenhouse gases to the maximum extent. But historical emissions and sea level rise have already begun so steps to adapt to a world where shorelines, coastal populations, and economies could be dramatically altered are now essential. This presents significant economic challenges in four areas. (1) Large expenditures for adaptation steps may be required but the extent of sea level rise and thus the expenditures are unknowable at this point. Traditional methods for comparing benefits and costs …

Informal Urban Displacement In Rio De Janeiro: Ecolimits And Disaster Biopolitics In The Favela Santa Marta, Charles L. Heck

FIU Electronic Theses and Dissertations

This dissertation examines the effect of environmental discourse and disaster risk reduction mapping in the favela Santa Marta, an urban informal settlement in the municipality of Rio de Janeiro, Brazil. With the world’s largest urban forest within the metro area, Rio de Janeiro is unusual for a metropolis of more than ten million people in the rapidly urbanizing country of Brazil. The government of Rio de Janeiro has attempted to control favela settlements since the early 20^th century, but beginning in the 1990s the prefecture began delimiting favela settlements with environmentally protected areas called ecolimits. According to the state’s …

The Conflict In Syria: Should The United States Get More Involved?, Jacob Peoples

Posters-at-the-Capitol

The purpose of this research is to explore the relations between Syria, Russia, and the United States in the Syrian civil war. The relationship has been in turmoil because of the complexities of the situation. Syria has been a designated state sponsor of terrorism since December 29, 1979, five years before the next designated state of Iran. Syria is a very important and strategic country and now more than ever has a large risk of being completely overrun by the newest terrorist group ISIS. The turmoil is possibly stemming initially from the result of a failed 1957 Central Intelligence Agency …

In Theory, There's Hope: Queer Co-(M)Motions Of Science And Subjectivity, Cordelia Sand

Masters Theses

Given the state of the planet at present —specifically, the linked global ecological and economic crises that conjure dark imaginings and nihilistic actualities of increasing resource depletion, poisonings, and wide-scale sufferings and extinctions—I ask What might we hope now? What points of intervention offer possibility for transformation? At best, the response can only be partial. The approach this thesis takes initiates from specific pre-discursive assumptions. The first understands current conditions as having been produced, and continuing to be so, through practices that enact and sustain neoliberal relations. Secondly, these practices are expressive of a subjectivity tied to a Cartesian worldview, …

Improving Small Community Flood Resilience: The Multiple Strategies Of Watershed Partnerships, Nicole Gillett

Masters Theses

Flooding in New England is often seen as a coastal concern, but inland, in the mountainous rural communities of New England, river floods present serious threats to communities and livelihoods. Recent large storm events such as Tropical Storm Irene, and rising concerns over climate change, have catalyzed conversations over the vulnerability of communities across inland New England to flooding. This thesis examines two very different watershed organizations in New England; the White River Partnership and Deerfield Creating Resilient Communities. Both are working towards flood resilience in their communities. My approach is not to judge “best practices” or to evaluate what …

(Un)Making The Food Desert: Food, Race, And Redevelopment In Miami's Overtown Community, William Hall

FIU Electronic Theses and Dissertations

In recent years, efforts to transform food environments have played a key role in urban revitalization strategies. On one hand, concerns over urban food deserts have spurred efforts to attract supermarkets to places where access to healthy food is difficult for lower income residents. On the other, the creation of new spaces of consumption, such as trendy restaurants and food retail, has helped cities rebrand low-income communities as cultural destinations of leisure and tourism. In cities around the US, these processes often overlap, converting poorer neighborhoods into places more desirable for the middle-class. My dissertation research examines the social and …

Estimating Economic Losses To Tourism In Africa From The Illegal Killing Of Elephants, Robin Naidoo, Brendan Fisher, Andrea Manica, Andrew Balmford

Rubenstein School of Environment and Natural Resources Faculty Publications

Recent surveys suggest tens of thousands of elephants are being poached annually across Africa, putting the two species at risk across much of their range. Although the financial motivations for ivory poaching are clear, the economic benefits of elephant conservation are poorly understood. We use Bayesian statistical modelling of tourist visits to protected areas, to quantify the lost economic benefits that poached elephants would have delivered to African countries via tourism. Our results show these figures are substantial (∼USD $25 million annually), and that the lost benefits exceed the anti-poaching costs necessary to stop elephant declines across the continent's savannah …

Characterization Of Landsat-7 To Landsat-8 Reflective Wavelength And Normalized Difference Vegetation Index Continuity, David P. Roy, V. Kovalskyy, Hankui Zhang, Eric F. Vermote, Lin Yan Dr., Sanath Sathyachandran Kumar, Alexey V. Egorov

GSCE Faculty Publications

At over 40 years, the Landsat satellites provide the longest temporal record of space-based land surface observations, and the successful 2013 launch of the Landsat-8 is continuing this legacy. Ideally, the Landsat data record should be consistent over the Landsat sensor series. The Landsat-8 Operational Land Imager (OLI) has improved calibration, signal to noise characteristics, higher 12-bit radiometric resolution, and spectrally narrower wavebands than the previous Landsat-7 Enhanced Thematic Mapper (ETM +). Reflective wavelength differences between the two Landsat sensors depend also on the surface reflectance and atmospheric state which are difficult to model comprehensively. The orbit and sensing geometries …

Canopy Height Estimation By Characterizing Waveform Lidar Geometry Based On Shape-Distance Metric, Eric Ariel L. Salas, Geoffrey M. Henebry

GSCE Faculty Publications

There have been few approaches developed for the estimation of height using waveform LiDAR data. Unlike any existing methods, we illustrate how the new Moment Distance (MD) framework can characterize the canopy height based on the geometry and return power of the LiDAR waveform without having to go through curve modeling processes. Our approach offers the possibilities of using the raw waveform data to capture vital information from the variety of complex waveform shapes in LiDAR. We assess the relationship of the MD metrics to the key waveform landmarks—such as locations of peaks, power of returns, canopy heights, and height …

Urban–Rural Contrasts In Central-Eastern European Cities Using A Modis 4 Micron Time Series, Monika Tomaszewska, Geoffrey M. Henebry

GSCE Faculty Publications

A primary impact of urbanization on the local climate is evident in the phenomenon recognized as the Urban Heat Island (UHI) effect. This urban thermal anomaly can increase the health risks of vulnerable populations to heat waves. The surface UHI results from emittance in the longer wavelengths of the thermal infrared; however, there are also urban anomalies that are detectable from radiance in the shorter wavelengths (3–5 micron) of the Middle Infrared (MIR). Radiance in the MIR can penetrate urban haze which frequently obscures urban areas by scattering visible and near infrared radiation. We analyzed seasonal and spatial variations in …

Teaching With Arcgis Pro, Larry Theller

Purdue GIS Day

For Fall semester 2016 the ABE department moved the course ASM 540 Basic GIS from ArcGIS Desktop 10.2 to ArcGIS Pro 1.3. This software from ESRI has a completely new look and feel, (ribbon-based rather than cascading menus) and is a true 64 bit application, capable of multi-threading, and built on Python 3. After ArcGIS Desktop 10.5 is released, desktop ends and the future release will be ArcGIS Pro; so it makes sense to switch sooner rather than later. This talk will discuss some issues and some observations of that process.

How Gis Will Support Next Gen 9-1-1, Jim I. Sparks

Purdue GIS Day

While most practitioners have a general awareness that GIS will play a more prominent role in Next Generation 9-1-1, few have much definitive information about what that means for Indiana GIS. This presentation will provide background information and an introduction to the requirements that NG 9-1-1 will place on our location data. Time will be left for some discussion centered on the challenges that are ahead of us.

Gis In Archaeology: The Pedestrian Survey Of Dana Island In Turkey, Noah Kaye, Gunder Varinlioglu, Nicholas K. Rauh

Purdue GIS Day

An international team of archaeologists conducted a surface survey of the remains on Dana Island, ancient Pithussae, near Silifke in south Coastal Turkey. The island sits 2 km offshore and is uninhabited. Architectural remains of stone quarries, large cisterns, houses and churches extend approximately 1.6 km along its western coast. At the crest of the mountain that rises above the shore stands the remains of an Iron Age fortress incorporated into later Byzantine structures. Relying on a base map constructed of the Google earth view of the island, digitized topographical maps, and an aerial photograph from 1990, the pedestrian team …
