Les Rues Des Tableaux: The Geography Of The Parisian Art Market 1815-1955, Léa Saint-Raymond, Félicie De Maupeou, Julien Cavero

Artl@s Bulletin

Building upon a preliminary socioeconomic analysis of the art dealers in Paris between 1815 and 1955 (ARTL@S Bulletin 2, n°2), this paper presents the findings of a spatial study of the Parisian art market in this period. Using serial geographical data drawn from a single, consistent source – the Bottin du commerce – we mapped the spatial evolution of art dealers over 140 years, using a geocoding system with composite locators. The article explores the different spatial dynamics of this market, and seeks to shed light on the links between the evolution of the Parisian economy as a whole and …

Identification Of Woodland Vernal Pools With Seasonal Change Palsar Data For Habitat Conservation, Laura Bourgeau-Chavez, Yu Man Lee, Michael Battaglia, Sarah L. Endres, Zachary Laubach, Kirk Scarbrough

Michigan Tech Publications, Part 1

Woodland vernal pools are important, small, cryptic, ephemeral wetland ecosystems that are vulnerable to a changing climate and anthropogenic influences. To conserve woodland vernal pools for the state of Michigan USA, vernal pool detection and mapping methods were sought that would be efficient, cost-effective, repeatable and accurate. Satellite-based L-band radar data from the high (10 m) resolution Japanese ALOS PALSAR sensor were evaluated for suitability in vernal pool detection beneath forest canopies. In a two phase study, potential vernal pool (PVP) detection was first assessed with unsupervised PALSAR (LHH) two season change detection (spring when flooded—summer when dry) and validated …

"Gravity Models" Applied To Projections For New Casinos: Techniques And Results, Will E. Cummings

International Conference on Gambling & Risk Taking

All developers of new casinos prepare, or have prepared for them, projections for the likely gaming-revenue performance of those casinos; in many cases; regulatory authorities in North America also require or commission independent third-party assessments of such performance. These projections are very frequently based on "gravity models," applying techniques pioneered by Reilly and Huff to analyze other retail activities in relation to the geographic distribution of competitors and potential customers. In this paper, I review roughly 80 examples of such applications from recent casino-licensing procedures in the U.S., and compare their results.

Increasing Accessibility For Map Readers With Acquired And Inherited Color Vision Deficiencies: A Re-Coloring Algorithm For Maps, Gretchen M. Culp

Dissertations, Theses, and Capstone Projects

Approximately 8% of the male population suffer from an inherited form of color vision deficiency (CVD). Age, diabetes, macular degeneration, cataracts and glaucoma result in eye defects including an acquired form of CVD. Inherited CVD is marked by a difficulty in discerning red from green, while acquired CVD is marked by a difficulty in discerning blue from green. A recent review of the cartographic literature revealed a deficit in studies on accessible maps for readers with the acquired form of CVD. In addition, research on accessible maps for readers with the inherited form of CVD was restricted to the design …

An Automated Approach For Sub-Pixel Registration Of Landsat-8 Operational Land Imager (Oli) And Sentinel-2 Multi Spectral Instrument (Msi) Imagery, Lin Yan, David P. Roy, Hankui Zhang, Jian Li, Haiyan Huang

GSCE Faculty Publications

Moderate spatial resolution satellite data from the Landsat-8 OLI and Sentinel-2A MSI sensors together offer 10 m to 30 m multi-spectral reflective wavelength global coverage, providing the opportunity for improved combined sensor mapping and monitoring of the Earth’s surface. However, the standard geolocated Landsat-8 OLI L1T and Sentinel-2A MSI L1C data products are currently found to be misaligned. An approach for automated registration of Landsat-8 OLI L1T and Sentinel-2A MSI L1C data is presented and demonstrated using contemporaneous sensor data. The approach is computationally efficient because it implements feature point detection across four image pyramid levels to identify a sparse …

Planning For Bike Share Connectivity To Rail Transit, Greg P. Griffin, Ipek N. Sener

Journal of Public Transportation

Bike sharing can play a role in providing access to transit stations and then to final destinations, but early implementation of these systems in North America has been opportunistic rather than strategic. This study evaluates local intermodal plan goals using trip data and associated infrastructure such as transit stops and bike share station locations in Austin, Texas, and Chicago, Illinois. Bike sharing use data from both cities suggest a weak relationship with existing rail stations that could be strengthened through collaborative, intermodal planning. The study suggests a planning framework and example language that could be tailored to help address the …

Can Significant Trends Be Detected In Surface Air Temperature And Precipitation Over South America In Recent Decades?, Daniel De Barros Soares, Huikyo Lee, Paul C. Loikith, Armineh Barkhordarian, Carlos R. Mechoso

Geography Faculty Publications and Presentations

Trends in near-surface air temperature and precipitation over South America are examined for the periods 1975–2004 and 1955–2004, respectively, using multiple observational and climate model data sets. The results for observed near-surface air temperature show an overall warming trend over much of the continent, with the largest magnitudes over central Brazil. These observed trends are found to be statistically significant using pre-industrial control simulations from the fifth phase of the Coupled Model Intercomparison Project (CMIP5) as the baseline to estimate natural climate variability. The observed trends are compared with those obtained in natural-only CMIP5 simulations, in which only natural forcings …

Applications Of Satellite Geodesy In Environmental And Climate Change, Qian Yang

USF Tampa Graduate Theses and Dissertations

Satellite geodesy plays an important role in earth observation. This dissertation presents three applications of satellite geodesy in environmental and climate change. Three satellite geodesy techniques are used: high-precision Global Positioning System (GPS), the Gravity Recovery and Climate Experiment (GRACE) and Interferometric Synthetic Aperture Radar (InSAR). In the first study, I use coastal uplift observed by GPS to study the annual changes in mass loss of the Greenland ice sheet. The data show both spatial and temporal variations of coastal ice mass loss and suggest that a combination of warm atmospheric and oceanic condition drove these variations. In the second …

Using Data To Build Community: Exploring One Model Of Geographically Specific Data Use In The Non-Profit Sector, Robert L. Fischer

Faculty Scholarship

Non-profit organizations strive to identify and build community in a variety of ways. A new development to assist non-profit organizations with this critical task is the use of Geographic Information Systems (GIS) that incorporate data assembled from area non-profit organizations. In this article, we investigate the reasons why non-profit organizations adopt these systems, their inclusion of various stakeholders in site launch, and the challenges for sustaining GIS use. Based on in-depth interviews conducted with sites that have adopted a prominent GIS application – the Urban Institute's Community Platform – we find that although non-profits may implement GIS with the expressed …

The Origin And Expansion Of The Eastern Red Fox, Adrienne Egge Kasprowicz

LSU New Orleans Theses and Dissertations

When new populations are first identified in a region there are multiple potential sources: introduction of a non-native species, extra-range expansion of a nearby population, or demographic growth of a previously unnoticed species. Red foxes were absent or rare in the mid-eastern portion United States until the late 1800s. Their origins potentially include natural population increase/expansion, translocations from Europe, and, eventually, 20th century fur farming. In this study I attempt to identify the relative impact of native expansion versus human mediated introductions of both colonial era European foxes and early 20^th century fur-farm foxes on the establishment of red …

Using Residential Location To Assess The Environmental Value-Action Gap Of Students At James Madison University, Emma Rose Martin

Senior Honors Projects, 2010-2019

This study focuses on the environmental Value-Action Gap of students at James Madison University (JMU) in Harrisonburg, Virginia. This gap occurs when a person has pro-environmental beliefs but does not have congruent actions. Often, there are other factors apart from a person’s values that influence his/her willingness to participate in eco-friendly behavior (Howell 2013). For this study, the factor of influence being addressed is location. When students live on-campus at JMU they are surrounded by ‘green’ initiatives. Understanding the diffusion of environmental behavior from on-campus living to off-campus living is important because the majority of a JMU student’s residency is …

Does Crime Correlate With Fear?: Analyzing The Spatial Relationship Between Perceptions Of Safety And Crime Using Sketch Maps And Geographic Information Systems (Gis) In The Main South Neighborhood Of Worcester, Ma, Marina Khananayev

Sustainability and Social Justice

The relationship between reported crime and residential perceptions of safety is understudied and inconclusive due to its highly complicated nature. This study seeks to narrow this gap by using sketch maps collected from residents about their safety and crime data. Two methods, one visual, the other statistical (Bivariate LISA), were tested using data from sketch maps drawn by about 95 survey respondents and crime data spanning three years (2011-2014). Data was disaggregated by gender, age, and length of residency. Visual analysis of results show that perceptions of safety occur at a fine scale. Respondents marked sketch maps at varying scales …
