An Analysis Of The Public Participation Processes Employed For An Urban Greenway Project, Maeve O'Connell
An Analysis Of The Public Participation Processes Employed For An Urban Greenway Project, Maeve O'Connell
Articles
The purpose of this study is to examine the public participation mechanisms employed for a proposed new infrastructure project. Public participation is a core characteristic of a contemporary democratic society as policy makers are increasingly encouraged to engage with citizens for learning and legitimacy. Participation is a loose concept with many forms and interpretations. This study explores the key characteristics of public participation formats, challenges to and the criteria for success. This analysis is then applied to the proposed local infrastructure consultation process. An additional survey is designed and its role in the public participation process is assessed. The processes …
The Perception Of Natural Resource Management In Nebraska: Efforts For Cross-Boundary Collaborative Management, Daniel Morales
The Perception Of Natural Resource Management In Nebraska: Efforts For Cross-Boundary Collaborative Management, Daniel Morales
School of Natural Resources: Dissertations, Theses, and Student Research
Nebraska’s agricultural landscapes are rapidly changing, affecting natural resources and their successful management. I utilized two surveys and scenario planning (Chapters 1: statewide survey, 2: local survey, and 3: scenario-planning workshop) to investigate attitudes and perceptions of natural resource management and cross-boundary collaboration. My first objective focused on determining what prevents Nebraskans from addressing natural resources challenges, considering demographics amongst generations and the type of areas they live in (rural versus urban). The second objective focused on whether landowners engaged with their community in managing natural resources. The third objective was to develop alternative future scenarios for the Denton Hills …

Government regulators cannot mitigate the loss of wetlands and coastal erosion alone. Nonprofits, uniquely situated between coastal property owners with personal interests and governments with regulatory interests, are positioned to mediate the interests of different parties while considering local context and individual circumstances. However, it is unclear what roles environmental nonprofits play within the network of actors. This study asks: (1) What roles do environmental nonprofit organizations play in local stakeholder network arrangements for wetlands conservation and shoreline management? (2) How are these roles interrelated? We use two frameworks describing the roles of nonprofits to examine the roles of environmental …

Global Climate Governance: Rising Trend Of Translateral Cooperation, Nataliya Stranadko
Public Affairs and Policy Faculty Publications and Presentations
The transformation from the Kyoto Protocol to the Paris Agreement has been analyzed by international relations scholars, international law, and transnational governance theory. The international relations literature looks at the climate regime from a perspective of power distribution, state interests, institutions, and multilateral negotiations. International law theory focuses on legal analysis and design of international climate agreements. The transnational governance literature examines the participation of transnational actors at different levels of governance. However, each of these theories overlooks a bilateral trend of cooperation in a multilateral setting that arises as part of the construction or reconstruction of the international regime. …

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. Results also help to foreground new …

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 …

Executive Summary
The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and …
Compliance Management Systems: Do They Make A Difference?, Cary Coglianese, Jennifer Nash
Compliance Management Systems: Do They Make A Difference?, Cary Coglianese, Jennifer Nash
All Faculty Scholarship
Regulatory compliance is vital for promoting the public values served by regulation. Yet many businesses remain out of compliance with some of the regulations that apply to them—presenting not only possible dangers to the public but also exposing themselves to potentially significant liability risk. Compliance management systems (CMSs) may help reduce the likelihood of noncompliance. In recent years, managers have begun using CMSs in an effort to address compliance issues in a variety of domains: environment, workplace health and safety, finance, health care, and aviation, among others. CMSs establish systematic, checklist-like processes by which managers seek to improve their organizations’ …
Building Urban Resilience In New York City, Eliseo Magsambol Cubol
Building Urban Resilience In New York City, Eliseo Magsambol Cubol
Antioch University Full-Text Dissertations & Theses
Existing research shows that cities around the world are now turning to urban resilience as a new approach to governing the urban climate challenges because of the increasing exposure of vulnerable populations and critical infrastructures in coastal cities and communities to extreme weather events. However, there is limited scholarly understanding about how cities and urban regions overcome challenges to the implementation of urban resilience. In particular, little research has focused on local stakeholder perspectives on urban resilience, which can offer valuable insights to help cities and urban regions address these challenges. To better understand stakeholder perspectives, this dissertation shares the …

Deploying Machine Learning For A Sustainable Future, Cary Coglianese
All Faculty Scholarship
To meet the environmental challenges of a warming planet and an increasingly complex, high tech economy, government must become smarter about how it makes policies and deploys its limited resources. It specifically needs to build a robust capacity to analyze large volumes of environmental and economic data by using machine-learning algorithms to improve regulatory oversight, monitoring, and decision-making. Three challenges can be expected to drive the need for algorithmic environmental governance: more problems, less funding, and growing public demands. This paper explains why algorithmic governance will prove pivotal in meeting these challenges, but it also presents four likely obstacles that …

Understanding The Factors Determining Green Public Procurement Practices Among Local Governments In The United States, Ana Maria Dimand
FIU Electronic Theses and Dissertations
One of the wicked problems communities face worldwide is climate change. Among potential solutions and current efforts is green public procurement (GPP), an innovative policy approach to change business as usual in the governmental sector. Local governments in the U.S. annually spend approximately $1.72 trillion on purchasing goods and services. Given substantial purchasing power of municipalities, GPP practices at the local level can incite a transition toward a more sustainable society. This study is the first to delineate the levels and variations of existing GPP practices among U.S. localities and examine the factors that facilitate or hinder GPP engagement.

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 …

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 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 …

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 …

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 …

Berry Important? Wolf Provisions Pups With Berries In Northern Minnesota, Austin T. Homkes, Thomas D. Gable, Steve K. Windles, Joseph K. Bump
United States National Park Service: Publications
Wolves (Canis lupus) primarily provision pups by catching mammalian prey and bringing remains of the carcass to the pups at a den or rendezvous site via their mouths or stomach. In August 2017, we observed an adult wolf regurgitating wild blueberries (Vaccinium spp.) to pups at a rendezvous site in the Greater Voyageurs Ecosystem, Minnesota, USA, which is the only known observation of wolves provisioning pups with wild berries. This observation, in combination with other evidence from the Greater Voyageurs Ecosystem, suggests wild berries might be a more valuable food source for wolves in southern boreal ecosystems than previously appreciated.
