Patuxent’S Long-Term Research On Wolves, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The gray wolf (Canis lupus) was one of the first species placed on the Endangered Species List in 1967. The Endangered Species Act of 1973 legally protected the wolf along with other listed species.

Patuxent Wildlife Research Center (Patuxent) in Laurel, MD, began its Endangered Wildlife Program in 1966, and U.S. Fish and Wildlife Service (USFWS) biologist Ray Erickson was assigned to lead it. In 1973, I was transferred to the program from Region 3 of the USFWS, having been employed there since 1969 to study wolves in Minnesota.

Endangered Species Act protection of the wolf fostered its quick …

An Ecological Perspective On Pertussis, Jody Ruth Goard

Walden Dissertations and Doctoral Studies

In 2012, 48,277 cases of pertussis were diagnosed in the United States. Pertussis, otherwise known as whooping cough, is a highly contagious, often debilitating, sometimes deadly, vaccine-preventable disease with an increasing incidence and death rate in the U.S, which may be due to vaccine exemptions. The purpose of this project was to determine if a relationship exists between immunization policies and immunization exemption rates, immunization exemption rates and pertussis rates, and immunization policies and pertussis rates in each state. Bronfenbrenner's bio-ecological framework was used to guide the project. Publically available data from the Centers for Disease Control and Prevention (CDC), …

Late Holocene Expansion Of Ponderosa Pine (Pinus Ponderosa) In The Central Rocky Mountains, Usa, Jodi R. Norris, Julio L. Betancourt, Stephen T. Jackson

United States National Park Service: Publications

Aim: Ponderosa pine (Pinus ponderosa) experienced one of the most extensive and rapid post-glacial plant migrations in western North America. We used plant macrofossils from woodrat (Neotoma) middens to reconstruct its spread in the Central Rocky Mountains, identify other vegetation changes coinciding with P. ponderosa expansion at the same sites, and relate P. ponderosa migrational history to both its modern phylogeography and to a parallel expansion by Utah juniper (Juniperus osteosperma).

Location: Central Rocky Mountains, Wyoming and Montana, and Black Hills, Wyoming and South Dakota, USA.

Methods: Plant macrofossils were analysed in …

Sustainable Safari Practices: Proximity To Wildlife, Educational Intervention And The Quality Of Experience, Ryan Devine Tarver

All Master's Theses

This research examines the perceived quality of experience for safari tourists in relation to wildlife viewing proximities and the potential of educational interventions as a management strategy to mitigate adverse impacts of safari participant crowding. Crowding emanates from the safari tourist preferences to obtain close proximity to animals, particularly large mammals. Recognizing these preferences and associated impacts to animal behavior defined in previous research, we develop and deliver a survey instrument designed to measure the perceived quality of experience of the safari tourist while controlling for the viewing proximity variable. The survey instrument involves responding to stock photos selected to …

Restorasi Tingkat Mikro Dalam Sistem Sosial Budaya Indonesia Untuk Mencegah Kematian Ibu, Sari Viciawati Machdum, Sofyan Cholid, Annisah -, Johanna Debora Imelda

Antropologi Indonesia

The complexity of culture and territory in Indonesia make social protection implementation challenging. Mothers have internal factors that forbid them to know and intend to use social health protection program so that the maternal mortality rate (MMR) in 2015 did not decrease. This study found that there were particular internal factor problems of the teenage mother. Besides being hampered by the administration because of their age, young mothers became vulnerable because of their immature psychological and emotional aspects. In the midst of unsupportive social and cultural conditions, teenage mothers altered to the weaker position. Whereas the growth and development of …

Examining The Cultural And Historical Impact Of The National Historic Site Designation In Nicodemus, Kansas, Ashley Adams Adams

Walden Dissertations and Doctoral Studies

America's National Historic Preservation Act promotes the conservation of irreplaceable sites such as Nicodemus, Kansas, an African American town founded by former slaves in 1877. The collaboration of the National Park Service (NPS) and civic partners is essential to meet the goal of preserving historic properties in Nicodemus and other minority communities. Although the NPS designated 5 Nicodemus buildings as a National Historic Site (NHS) in 1996, the few remaining residents struggle to preserve the site and attract visitors. The purpose of this ethnographic study was to explore the effects of NPS policies related to African American historic and cultural …

The Industrial Impact On Wetlands In Jinja And The Nexus Of Industry, Wetlands, And Community (A Rights-Based Sustainable Development Approach), Ranger Ruffins

Independent Study Project (ISP) Collection

Uganda is a beautiful country filled with an extensive amount of natural resources, one of the most profound being wetlands. It is said that these wetlands are a crucial source of food and water for almost 3 million people (NEMA, 2012 and Oguttu et.al, 2008). They also provide many more invaluable socioeconomic benefits for the country. As Uganda experiences increasing development as well as a rapidly increasing population, the wetlands become increasingly necessary, at the same time they become increasingly threatened. It is written in the 1995 Ugandan constitution that Ugandan policy is aimed at ensuring sustainable development for the …

Longitudinal Variation In Environmental Impact At Rock Climbing Areas In The Red River Gorge Limits Of Acceptable Change Study Area, Daniel Boone National Forest, Kentucky, Nicholas Walendziak

Online Theses and Dissertations

Recreation ecology began in the 1960s to measure the impacts of recreation on ecosystems. Area of environmental impact is an important objective to assess recreational impact. However, few researchers have examined the trends of these impacts over time. This study measures the environmental area of impact at eight climbing areas, in Red River Gorge, Kentucky, over a six year period, to determine impact trends. The results of this research will help recreation ecologists and land managers understand environmental impacts over time, and possibly predict future impact scenarios. The hypothesis of this research is the total mean area of impact at …

Three Essays On Public Organizations, Changgeun Yun

Theses and Dissertations--Public Policy and Administration

Organizations play key roles in modern societies. The importance of organizations for a society requires an understanding of organizations. In order to fully understand public organizations, it is necessary to recognize how organizational settings affect subjects of organizations and organizing. Although public and private organizations interrelate with each other, the two types are not identical. In this dissertation, I attempt to describe public organizations in their own setting by discussing three important topics in public organization theory: (1) innovation adoption in the public sector; (2) representative bureaucracy; and (3) decline and death of public organizations.

In Chapter II, I scrutinize …

The Relationship Of State Political Instability And Economic Failure To Predatory Organized Crime In Multiple Nations: A Global Comparative Anaylsis, Terrance Ruth

Electronic Theses and Dissertations

This dissertation examines the relationship of political instability and economic failure to predatory organized crime in multiple nations. This is an important issue since each year the increase in predatory crime networks contributes to international economic failure, security risks, and the spread of organized crime. In an effort to understand the relationship between state failure and economic failure on the one hand, and organized crime on the other, this study will seek to address three goals. First, the study tests the degree to which variables that imply economic failure and state failure correlate with predatory organized crime. Second, the study …

Biofouling : A Means Of Aquatic Species Transfer, Anne Bouyssou, Josefin Madjidian

NSBWO

Ships carry seawater in their ballast tanks when they are not fully loaded with cargo, in order to maintain adequate trim, draught and stability, adjust list and limit stresses on the hull. It is now well documented that the water pumped into the ship contains aquatic organisms – which can also sink to the sediments at the bottom of tanks – and that these organisms are thereby transferred from the port of origin to the destination. But it is seldom mentioned that aquatic organisms are also found on the outside of ships, attached on their hulls and appendages, as a …

Advocacy For Marine Management: Contributions To A Policy Advocacy Initiative In The Maldives, Neal Collins

Capstone Collection

On June 5, 2009 a 42-­‐km2 area of coral reef situated in the Alif Dhaalu (South Ari) atoll of the Republic of Maldives was designated the South Ari Atoll Marine Protected Area (S.A. MPA) due to a globally significant whale shark aggregation site. The whale shark is notorious for its gargantuan size and docile nature, which has led to a burgeoning tourist industry that gives people the opportunity to swim with the gentle giants in tropical sites such as the Maldives. The S.A. MPA receives tens of thousands of visitors a year that engage in whale shark excursions, however, there …

Public Land And Its Management: Why The Research Is Not Enough, Corinne Calhoun

Pomona Senior Theses

Ecological research, both basic and applied, can inform management decisions on public land in a number of ways. Most importantly, it can illuminate any negative effects of a given land use practice as well as the causes behind that effect. This type of information can be important to a management agency, such as the BLM, with a multi-use mission as these studies indicate under what management regimes a land use is in contradiction with other goals, such as conservation or restoration.

The current body of research, however, is flawed. In order to make fully informed decisions, land managers are in …

United States Food Law Update: Shrouded By Election-Year Politics, State Initiatives And Private Lawsuits Fill In The Gaps Created By Congressional And Agency Ossification, A. Bryan Endres, Lisa R. Schlessinger, Rachel Armstrong

Journal of Food Law & Policy

Observers of food law in the 2012 presidential election year witnessed a dramatic slowing of federal initiatives-perhaps arising from a desire by both Congress and the administration to avoid upsetting critical constituent groups during a year seemingly dominated by campaigns and endless talking points. For example, Congress failed to take action on a unique compromise between what some had considered mortal enemies-the Humane Society of the United States and United Egg Producers-that would implement a federal animal welfare standard for laying hens in return for abandoning ballot measures in various states. Similarly, the FDA waited until the early days of …

The Impact Of State Characteristics On College Graduation Rates At Land-Grant Institutions, Melissa Bridges

Graduate Theses and Dissertations

As our nation's economy has become increasingly knowledge-based, an educated citizenry is paramount to maintaining a competitive edge in a global marketplace. Thus, college participation and completion have emerged as the gateway to survival and growth for individuals, states, and the nation, making college completion rates a top priority. Stakeholders have begun to equate graduation rates with institutional quality and performance and often use such data to make judgments, create policies, and allocate funding. However, graduation rates are not fully understood and numerous scholars urge caution when interpreting and utilizing single outcome measures. The purpose of this cross-sectional ecological study …

The Role Of Comparative Analysis In Borderlands Studies, Christine Brenner

Public Policy and Public Affairs Faculty Publication Series

The paper explores the question, “What global core competencies can public administration glean from the field of borderlands studies?” Borderlands studies have traditionally focused on the geographic area on or near the frontier demarcation between nation states. Borderlands also function as buffering or mediating zones where often markedly different countries develop complex networked administrative systems to permit the passage of peoples and products across territorial boundaries. In this way borderlands often shape the administrative and policy decisions made in the centers of national power. This paper employs content analysis to review ten years of the Journal of Borderlands Studies (2011 …

Assessing The Equity Implications Of Greenspace Distribution In An Arid Region, Abdelatif Eldeb

Open Access Theses & Dissertations

In the last few decades, vegetation deterioration is receiving increased attention because of its adverse impacts on societal and human health, environmental sustainability, and quality of life. I have selected two cities in Chihuahua Desert region (El Paso and Juarez) as case study sites to develop a novel and applicable methodology for integrating remotely sensed data of different spectral and spatial resolutions into an analysis of the spatial distribution of an urban amenity. The primary objective of this research is to determine if the spatial distribution of greenspace in 2010 is equitable with respect to socio-demographics in El Paso and …

Understanding Resistance To Standardization In Education: The Tragedy Of The Commons As A Theoretical Framework, Grinell Smith, Colette Rabin

Faculty Publications

The purpose of this paper is to articulate how a theory, developed in 1968 by Garrett Hardin to describe how shared resources, or “commons” can become depleted, also elucidates the mechanism by which standardization of educational outcomes and assessment have come to dominate current education discourse. We then present results of a case study of a school struggling to succeed within a context of a district’s hyper-focus on standardized measures of success, and employ the theory to illustrate its usefulness to explain what we found at the school site. We believe this theoretical framework provides interesting perspectives on current trends …

Firearms, Youth Homicide, And Public Health, Robert S. Levine, Irwin Goldzweig, Barbara Kilbourne, Paul Juarez

Sociology Faculty Research

Homicide is seven times as common among U.S. non-Hispanic Black as among non-Hispanic White youth ages 15 to 24 years. In 83% of these youth homicides, the murder weapon is a firearm. Yet, for more than a decade, the national public health position on youth violence has been largely silent about the role of firearms, and tools used by public health professionals to reduce harm from other potential hazards have been unusable where guns are concerned. This deprives already underserved populations from the full benefits public health agencies might be able to deliver. In part, political prohibitions against research about …

Disparities In Park Availability, Features, And Characteristics By Social Determinants Of Health Within A U.S.-Mexico Border Urban Area, Amir Kamel

Open Access Theses & Dissertations

Background: Parks have been shown to be a key feature in the built environment that promote physical activity and positively influence health. However, a number of studies have highlighted that park availability, park features (e.g., park facilities, amenities, and aesthetic features), and park characteristics (e.g., quality/safety concerns of the park and surrounding neighborhood) are not equally distributed across neighborhoods in the U.S, specifically areas of low socioeconomic status and diverse racial/ethnic composition. The overall aim of this study was to examine and describe park availability, park features, and park characteristics, and determine their association with two social determinants of health …

Review Of The Leadership Of George Bush: An Insider's View Of The Forty-First President. By Roman Popadiuk, Caroline Heldman

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The Leadership of George Bush is infused with a sentimentality exemplified by the book's opening statement describing the Bushes' emotional response to Bush 43's election to the presidency: "George Bush sat straight up, his back rigid but his chest heaving slightly as he sought to hold back tears. Barbara Bush sat quietly, unmovable, a glint of satisfaction and pride sparkling in her eyes." Despite the author's proximity and long-time affiliation, the book provides scant new information about Bush 41 's presidency, mostly because the author fails to connect it with larger literatures on presidential leadership and executive management. Instead, it …

Infectious Diseases In Yellowstone’S Canid Community, Emily S. Almberg, Paul C. Cross, L. David Mech, Doug W. Smith, Jennifer W. Sheldon, Robert L. Crabtree

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Each summer Yellowstone Wolf Project staff visit den sites to monitor the success of wolf reproduction and pup rearing behavior. For the purposes of wolf monitoring, Yellowstone National Park (YNP) is divided into two study areas, the northern range and the interior, each distinguished by their ecological and physiographical differences. The 1,000 square kilometer northern range, characterized by lower elevations (1,500–2,200 m), serves as prime winter habitat for ungulates and supports a higher density of wolves than the interior (20–99 wolves/1,000 km² versus 2–11 wolves/1,000 km²). The interior of the park encompasses 7,991 square kilometers, is higher …

An Ecological Analysis Of Social And Economic Influences On Black And White Infant Mortality Risk In Orange County, Fl, Littleton, Vanessa Lopez

Electronic Theses and Dissertations

Black health disparities are a salient public health issue with blacks in every socioeconomic level at a greater health disadvantage than their white counterparts. In particular, disparity in infant mortality rates between blacks and whites have widened in recent decades to differentials never before experienced in the United States. Social ecologists investigating the myriad of individual and environmental risk factors have failed to fully account for the persistent differential. This study examines the relationships between individual and environmental influences on the health risk experienced by blacks, whites, as well as the differential between the two populations. This multi-level analysis was …

Use Of Cranial Characters In Taxonomy Of The Minnesota Wolf (Canis Sp.), L. David Mech, Ronald M. Nowak, Sanford Weisberg

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Minnesota wolves (Canis sp.) sometimes are reported to have affinity to a small, narrow-skulled eastern form (Canis lupus lycaon Schreber, 1775) and sometimes to a larger, broader western form (Canis lupus nubilus Say, 1823). We found that pre-1950 Minnesota wolf skulls were similar in size to those of wolves from southeastern Ontario and smaller than those of western wolves. However, Minnesota wolf skulls during 1970–1976 showed a shift to the larger, western form. Although Minnesota skull measurements after 1976 were unavailable, rostral ratios from 1969 through 1999 were consistent with hybridization between the smaller eastern wolf and …

Concurrent Sexual Partnerships Do Not Explain The Hiv Epidemics In Africa: A Systematic Review Of The Evidence, Larry Sawers, Eileen Stillwaggon

Economics Faculty Publications

The notion that concurrent sexual partnerships are especially common in sub-Saharan Africa and explain the region’s high HIV prevalence is accepted by many as conventional wisdom. In this paper, we evaluate the quantitative and qualitative evidence offered by the principal proponents of the concurrency hypothesis and analyze the mathematical model they use to establish the plausibility of the hypothesis.

We find that research seeking to establish a statistical correlation between concurrency and HIV prevalence either finds no correlation or has important limitations. Furthermore, in order to simulate rapid spread of HIV, mathematical models require unrealistic assumptions about frequency of sexual …
