Changing Snow Seasonality In The Highlands Of Kyrgyzstan, Monika Tomaszewska, Geoffrey Henebry May 2018

Changing Snow Seasonality In The Highlands Of Kyrgyzstan, Monika Tomaszewska, Geoffrey Henebry

GSCE Faculty Publications

Few studies have examined changing snow seasonality in Central Asia. Here, we analyzed changes in the seasonality of snow cover across Kyrgyzstan (KGZ) over 14 years from 2002/03–2015/16 using the most recent version (v006) of MODIS Terra and Aqua 8 day snow cover composites (MOD10A2/MYD10A2). We focused on three metrics of snow seasonality—first date of snow, last date of snow, and duration of snow season—and used nonparametric trends tests to assess the significance and direction of trends. We evaluated trends at three administration scales and across elevation. We used two techniques to assure that our identification of significant trends was …

The Impacts Of Natural Disasters On Educational Attainment: Cross-Country Evidence From Macro Data, Lois Onigbinde

Master's Theses

Do natural disasters impact educational attainment? Education as a paramount factor of economic development suffers from the uncontrollable effects of these increasing events from storms to floods, earthquakes to wildfires. Globally, educational resources are destroyed, directly and indirectly, students and teachers are displaced or killed, parents’ income is affected because of natural disasters. Investments in human capital for rich- and low-income countries are exposed to the uneven impact of natural disasters that adjusts household and country-level decisions, leaving them to short and long-run losses. Exploring the influence of natural disasters on secondary school attainment across a sample of 85 countries …


Evaluation Of A Continuous Air Monitoring System On An Unmanned Aerial Vehicle For Measurement Of Airborne Radioactive Material, Adam Pfannenstein May 2018

Evaluation Of A Continuous Air Monitoring System On An Unmanned Aerial Vehicle For Measurement Of Airborne Radioactive Material, Adam Pfannenstein

UNLV Theses, Dissertations, Professional Papers, and Capstones

The release of airborne radioactive material presents a health risk hazard to many individuals, emergency responders and public. It is necessary to characterize the unknown radioactive dangers produced in the event of these incidents. Advantages to utilizing unmanned aerial systems in this effort are personnel risk reduction and quick attainment of data points in a plume. By pairing a continuous air monitor and detector with a drone, radioactive material concentration can be quantified, and thus the extent of potential doses can be estimated. A small, low-flow air sampler with a Geiger-Mueller counter was characterized using measurements of sources representing a …


Climate Change Amplifications Of Climate‐Fire Teleconnections In The Southern Hemisphere, Michela Mariani, Andrés Holz, Thomas T. Veblen, Grant J. Williamson, Michael-Shawn Fletcher, David M. J. S. Bowman May 2018

Climate Change Amplifications Of Climate‐Fire Teleconnections In The Southern Hemisphere, Michela Mariani, Andrés Holz, Thomas T. Veblen, Grant J. Williamson, Michael-Shawn Fletcher, David M. J. S. Bowman

Geography Faculty Publications and Presentations

Recent changes in trend and variability of the main Southern Hemisphere climate modes are driven by a variety of factors, including increasing atmospheric greenhouse gases, changes in tropical sea surface temperature, and stratospheric ozone depletion and recovery. One of the most important implications for climatic change is its effect via climate teleconnections on natural ecosystems, water security, and fire variability in proximity to populated areas, thus threatening human lives and properties. Only sparse and fragmentary knowledge of relationships between teleconnections, lightning strikes, and fire is available during the observed record within the Southern Hemisphere. This constitutes a major knowledge gap …


The Impacts Of Green Spaces On Crime In New York City, Matthew Edward Iannone Jr. May 2018

The Impacts Of Green Spaces On Crime In New York City, Matthew Edward Iannone Jr.

Student Theses 2015-Present

From the early 1960s through the mid-1990s, crime in New York City ran rampant. With a gradually dwindling police during this time, a high unemployment rate, and an rapidly increasing metropolitan population, crime peaked in the early 1990s, with the murder rate hitting a record-high of 2,245 in 1990. When Mayor Rudy Giuliani took office in 1994 and appoint Bill Bratton as the NYPD police commissioner, these rates immediately plunged. Numerous factors may have contributed to this sudden decline in crime: the police force grew significantly through the 1990s, more criminals were placed and held in prison, and the economic …

United States National Park Service: Publications

Outbreaks of coral diseases continue to reduce global coral populations. In the Caribbean, yellow band is a severe and wide-spread disease that commonly affects corals of the Orbicella spp. complex, significantly impeding coral reproduction, and hindering the natural recovery of Orbicella spp. populations. Caribbean yellow-band disease (CYBD) lesions may be severe, and often result in the complete loss of coral tissue. The slow spread of CYBD, however, provides an opportunity to test methods to mitigate the disease. Here we report the results of in situ experiments, conducted within Buck Island Reef National Monument in St. Croix, USVI, to test the …

Compost Rich Of Resistance: Wayfinding In Tel Aviv And Jerusalem, Taylor K. Miller May 2018

Compost Rich Of Resistance: Wayfinding In Tel Aviv And Jerusalem, Taylor K. Miller

Journal of Social Theory in Art Education

It is not common to travel to a region searching for what is wrong and askew. But this is precisely how I move through greater Palestine-Israel each time I visit. Explosions and incessant pummeling have forced the sidewalks and retaining walls to heave–Styrofoam slabs serve as an equally hasty and hideous shim. But in this, there is hope. Even where the sidewalk momentarily ends–likely that in just a few months a new road, deeper into the West Bank will be built–it is glaring that these foundations are laid at an unsustainable pace. In a land where the forest often obscures …

Equitable Sustainable Development In Small American Cities: The Northend Greenway And The Path Forward, Amelia Morrison May 2018

Equitable Sustainable Development In Small American Cities: The Northend Greenway And The Path Forward, Amelia Morrison

Senior Honors Projects, 2010-2019

As global climate change prompts a demand for “green” urban development, the representation of sustainability as a panacea to all environmental, economic, and social issues has been increasingly challenged by social justice advocates. In particular, critics of the social component of this supposedly balanced sustainability model have characterized holistic sustainability rhetoric as an appropriation of equity discourse to serve the interests of a narrow set of affluent consumers. The ongoing question of who benefits from sustainable development has revealed highly problematic patterns of displacement and gentrification that fall disproportionately on low-income neighborhoods and communities of color. This tension is examined …

The Paradox Of Cracker Barrel: A Case Study On Place And Placelessness, Meredith Gregory May 2018

The Paradox Of Cracker Barrel: A Case Study On Place And Placelessness, Meredith Gregory

Departmental Honors & Graduate Capstone Projects

Place relates to the concept that a particular space can have certain features which make it recognizable and which can inspire an emotional attachment. Placelessness refers to the eradication of unique features, stripping away elements that make one place different from another. Cracker Barrel exists as simultaneously placeless and placefull, putting both of these elements, which at first seem like opposites, to work bringing millions of people back in time to 19th century rural America every time they walk through the door. This research explores this paradoxical notion by utilizing content and semiotic analyses in an analysis of user-generated Yelp! …

Degrowth Lessons From Cuba, Claire S. Bayler May 2018

Degrowth Lessons From Cuba, Claire S. Bayler

Sustainability and Social Justice

Cuba is the global leader in practicing agroecology, but agroecology is just one component of a larger climate-ready socio-economic system. Degrowth economics address the need to constrain our total global metabolism to within biophysical limits, while allowing opportunity and resources for "underdeveloped" countries to rebuild themselves under new terms. Degrowth recognizes the role of overdeveloped countries in surpassing the ecological limits of our planet at the cost of wellbeing for billions of dispossessed people within and between countries. Cuba's circumstances during and following the Special Period exemplify both sides of the degrowth scenario, as well as demonstrating policy and grassroots …


Modified Landscapes, Esther Nooner May 2018

Modified Landscapes, Esther Nooner

Graduate Theses and Dissertations

Modified Landscapes is a body of work that reflects serious thought regarding Nature and its future. My personal experience and beliefs are at the core of why I believe this subject to be of great importance and why it will sustain many artists’ investigations for the time to come. The influences that informed this process are explored through experiences I had traveling, reading and exploring the photograph as a material object. The manipulation of the photograph is meant to question the beautiful, untouched scene and break the Romantic gaze that is historically tied to representations of Nature and insist upon …

Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms May 2018

Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms

United States National Park Service: Publications

Abstract

Prior to 2014, bat research at Devils Tower National Monument (DETO) focused on bats present during the summer months. Biologists at DETO assumed local bats were strictly summer residents due to the presumed lack of typical habitat features associated with bat hibernation, such as caves and mines. This lack of traditional hibernacula features at DETO discouraged staff and research cooperators from studying winter bat populations. Despite the earlier assumption that bats were unlikely to hibernate on the monument, DETO documented significant winter bat activity through passive winter acoustic monitoring. This study is the first study at DETO that documents …


Decisions Set In Stone: Spatial Analyses Of Ozark Rock Art Sites, Elements, And Motifs With Gis, Jordan Lee Schaefer May 2018

Decisions Set In Stone: Spatial Analyses Of Ozark Rock Art Sites, Elements, And Motifs With Gis, Jordan Lee Schaefer

Graduate Theses and Dissertations

This thesis uses Geographic Information Systems (GIS) to spatially analyze rock art distributions in the Salem Plateau section of the Arkansas Ozarks. Statistical tests, such as chi-square and t-testing, are applied to provide an objective view of rock art patterning in relation to the overall landscape. The data collected from these methods allow one to discern the locational preferences for rock art, which potentially reveal cultural details about the people involved with its creation. Multiple analytical perspectives are applied throughout, initially focusing on comparisons with expected values and random points. Later statistical tests use bluff shelter distributions as reference data …
