“You Can’T Hide Behind Being A House”: Examining The Policy Process, Design, And Implementation Of Short-Term Rental Regulations, A Case Study Of Nashville, Tn, Jamie L. Cathey
All Dissertations
Following the economic crash of 2008, the rapid expansion of platform capitalism and the recruitment of others to work for themselves using a company’s platform, has led to a ‘paradigm shift’ in which a sharing economy business model has enabled small entrepreneurial endeavors to become industry giants (Srnricek, 2017). One such platform, Airbnb, has created a new, informal tourism accommodation sector that is bringing with it questions of regulation and community impact. Airbnb regulation thus is a growing national and international trend affecting cities of all sizes and forcing policy response and change at the local government level. Current trends …

U.S. Policing As Racialized Violence And Control: A Qualitative Assessment Of Black Narratives From Ferguson, Missouri, Jason M. Williams
U.S. Policing As Racialized Violence And Control: A Qualitative Assessment Of Black Narratives From Ferguson, Missouri, Jason M. Williams
Department of Justice Studies Faculty Scholarship and Creative Works
U.S. policing has long been captured within a master narrative of colorblind consensus; however, distinct lived experiences between community groups depict grave disparities in law enforcement experiences and perceptions. Orthodox conceptions of law enforcement ultimately silence marginalized voices disproportionately affected by negative contacts with law enforcement. Centering data in critical theory, this study will present thematic results from semi-interviews gathered in Ferguson, M.O., during a critical ethnographic research project. Themes reveal experiences and perceptions of racialized and violent policing, the unique position of Black officers, and regard for the impact police have on children.

Executive Summary
Fish communities are an important component of aquatic systems and are good bioindicators of ecosystem health. Land use changes in the Midwest have caused sedimentation, erosion, and nutrient loading that degrades and fragments habitat and impairs water quality. Because most small wadeable streams in the Heartland Inventory and Monitoring Network (HTLN) have a relatively small area of their watersheds located within park boundaries, these streams are at risk of degradation due to adjacent land use practices and other anthropogenic disturbances. Shifts in the physical and chemical properties of aquatic systems have a dramatic effect on the biotic community. …

Executive Summary
Changing climate and introduced species are placing an increasing number of species at risk of extinction. Increasing extinction risk is increasing calls to protect species by relocating, or translocating, them to locations with more favorable biotic or climatic conditions. Managed relocation, or assisted migration, of species entails risks to both the conservation target organisms being moved as well as the recipient ecosystems into which they are moved.
Recognizing this risk, calls have been made for practitioners interested in considering a managed relocation project to engage in a serious risk assessment prior to advancing a project. We engaged a …

Development Of A Modified Floristic Quality Index As A Rapid Habitat Assessment Method In The Northern Everglades, Rebakah E. Gibble, Donatto D. Surratt
United States National Park Service: Publications
Floristic quality assessments (FQA) using floristic quality indices (FQIs) are useful tools for assessing and comparing vegetation communities and related habitat condition. However, intensive vegetation surveys requiring significant time and technical expertise are necessary, which limits the use of FQIs in environmental monitoring programs. This study modified standard FQI methods to develop a rapid assessment method for characterizing and modeling change in wetland habitat condition in the northern Everglades. Method modifications include limiting vegetation surveys to a subset of taxa selected as indicators of impact and eliminating richness and/or abundance factors from the equation. These modifications reduce the amount of …
Fire Monitoring Handbook
United States National Park Service: Publications
Fire is a powerful and enduring force that has had, and will continue to have, a profound influence on National Park Service (NPS) lands. Fire management decisions within the National Park Service require information on fire behavior and on the effects of fire on park resources. With good reason, the public is holding park management increasingly accountable, especially in the area of fire management. Federal and state agencies are instituting progressively more stringent guidelines for burning, monitoring, and evaluation. The impetus behind these guidelines and the purpose of this handbook are to ensure that management objectives are being met, to …

And Lettuce Is Nonanimal: Toward A Positive Theory Of Voluntary Action, Roger A. Lohmann
And Lettuce Is Nonanimal: Toward A Positive Theory Of Voluntary Action, Roger A. Lohmann
Faculty & Staff Scholarship
Much recent conceptual and theoretical effort to identify and define the kinds of voluntary action that take place outside households, economic markets and governments has a consistent emphasis on negation: It seems to define these matters by what they are not: not for profit, or nonprofit, nongovernmental, unproductive, inefficient, examples of contract failure, market failure, government failure and more. This paper is a beginning effort to shift the emphasis to the positive and the describe and explain what voluntary action is and what it consists of. It proposes the beginnings of an economics of common goods production, and differentiates such …

Citizen Engagement In Aquatics Equity: The Case Of Winston Waterworks, Steven N. Waller Phd, James H. Bemiller Jd, Emliy J. Johnson, Chermaine D. Cole, Jason Scott Phd, Angela Wozencroft, Phd
International Journal of Aquatic Research and Education
Historically, swimming pools have been a source of inequity when it comes to the distribution of recreation services in the United States. Many of the problems that correlate with the inequitable allocation of recreation resources including public swimming pools began with ideas about race, geography, poor planning practices and faulty policymaking (Rothstein, 2017). Moreover, one of the primary outcomes of engaged, inclusive planning is equity in the provision of recreation programs and facilities. In this essay, we offer a summary of key legal cases that help address questions related resource allocation related to public swimming pools. Finally, we present a …

Acoustically Advertising Male Harbour Seals In Southeast Alaska Do Not Make Biologically Relevant Acoustic Adjustments In The Presence Of Vessel Noise, Leanna P. Matthews, Michelle E.H. Fournet, Christine Gabriele, Holger Klinck, Susan E. Parks
United States National Park Service: Publications
Aquatically breeding harbour seal (Phoca vitulina) males use underwater vocalizations during the breeding season to establish underwater territories, defend territories against intruder males, and possibly to attract females. Vessel noise overlaps in frequency with these vocalizations and could negatively impact breeding success by limiting communication space. In this study, we investigated whether harbour seals employed anti-masking strategies to maintain communication in the presence of vessel noise in Glacier Bay National Park and Preserve, Alaska. Harbour seals in this location did not sufficiently adjust source levels or acoustic parameters of vocalizations to compensate for acoustic masking. Instead, for every 1 dB …

Context In human-dominated landscapes, habitat fragmentation and barriers to movement can interrupt gene flow. While often considered at a local extent, regional analyses are also needed to reveal broader landscape-mediated population processes.
Objectives To explore the relationship between patterns of gene flow and fragmentation resulting from urbanization across southern California, we used the bobcat as an indicator species. We assembled data for a landscape level genetic analysis across southern California from both archived and new samples, including two northern Californian populations for comparison, to identify local and regional areas affected by isolation.
Methods Our regional analyses focused on a dataset …
Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors
Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors
United States National Park Service: Publications
Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 percent of 1–3 anthropogenic carbon dioxide emissions. Climate-driven vegetation models 4,5 typically predict that this tropical forest ‘carbon sink’ will continue for decades . Here we assess trends in the carbon sink using 244 structurally intact African tropical forests spanning 11 countries, compare them with 321 published plots from Amazonia and investigate the underlying drivers of the trends. The carbon sink in live aboveground biomass in intact African tropical forests has been stable for the three decades to …

Estimation Of Available Epinephrine Dose In Expired And Discolored Autoinjectors Via Quantitative Smartphone Imaging, Amirus Saleheen, Bill M. Campbell, Rebecca A. Prosser, Christopher A. Baker
United States National Park Service: Publications
Epinephrine autoinjectors (EAIs) are important first aid medications for treating anaphylaxis. A 10-fold price increase over the past 12 years and evidence that expired EAIs may still contain significant doses of available epinephrine have motivated interest in the efficacy of expired EAIs as treatments of last resort. Degradation of expired EAIs, which can be caused by improper storage conditions, results in various degrees of discoloration of the epinephrine solution. Previous studies have determined that significant epinephrine remains available in expired EAIs, but these have only considered EAIs that show no discoloration. Here, we investigate the potential for colorimetric estimation of …

Nurse Rock Microclimates Significantly Buffer Exposure To Freezing T Temperature And Moderate Summer Temperature, Joshua L. Conver, Elliott Yarwood, Lucas D. Hetherington, Don E. Swann
United States National Park Service: Publications
Nurse tree canopies mitigate exposure to freezing temperatures that could result in injury or mortality to the saguaro cactus (Carnegiea gigantea). Abiotic objects have been hypothesized to provide similar beneficial microclimates. We used data loggers at 11 nurse rock sites to record daily daytime summer maximum and winter nighttime minimum temperatures at Saguaro National Park, Arizona, to examine the effectiveness of rocks to moderate seasonal temperature extremes in the microclimate. Temperatures at rock sites averaged 2 °C warmer than exposed open control sites in winter. We found that the efficiency of rocks to act as insulators significantly increased as temperature …
Effects Of Culling White-Tailed Deer On Tree Regeneration And Microstegium Vimineum, An Invasive Grass, John Paul Schmit, Elizabeth R. Matthews, Andrejs Brolis
Effects Of Culling White-Tailed Deer On Tree Regeneration And Microstegium Vimineum, An Invasive Grass, John Paul Schmit, Elizabeth R. Matthews, Andrejs Brolis
United States National Park Service: Publications
Reduction of forest regeneration due to overbrowsing by white-tailed deer is a growing concern for land managers. Abundant deer can impede forest regeneration through direct predation on tree seedlings. Additionally high deer density can facilitate the establishment of a dense understory of browse tolerant plant species that shades seedlings and persists even in the absence of deer. In response to these challenges, land managers have sought to reduce deer herds to restore tree regeneration, but few studies have evaluated the effectiveness of this management. Our study took place in Catoctin Mountain Park, a US National Park Service unit with a …

United States National Park Service: Publications
The thermal evolution procedure used by most monitoring programs in the United States to determine carbonaceous aerosol concentrations is referred to as the thermal‐optical reflectance method, where an aerosol sample that has been collected on a quartz filter is heated and evolved carbon is characterized as either organic (OC) or light absorbing carbon (LAC). Evolved carbon assigned to OC is multiplied by a factor, Roc, to achieve an estimate of organic mass. Over the last 10–15 years, Roc, estimated through multiple linear regression analysis of data collected in the Interagency Monitoring of Protected Visual Environments (IMPROVE) program, has increased at …
