Analysis Of Land Use/Land Cover Change Impacts Upon Ecosystem Services In Montane Tropical Forest Of Rwanda: Forest Carbon Assessment And Redd+ Preparedness, Mcard Joseph Mlotha

Antioch University Dissertations & Theses

Changes in forest cover especially changes within tropical forests, affect global climate change, together with ecosystems and forest carbon. Forests play a key role in both carbon emission and carbon sequestration. Efforts to reduce emissions through reduced deforestation and degradation of forests have become a common discussion among scientists and politicians under the auspices of the United Nations Programme on Reducing Emissions from Deforestation and Forest Degradation (UN-REDD Programme). This dissertation research assessed the impacts of land use land cover change upon ecosystem services from a protected area focusing on forest carbon distribution and vegetation mapping using remote sensing and …

Divergent Pathways On The Road To Sustainability: A Multilevel Model Of The Effects Of Geopolitical Power On The Relationship Between Economic Growth And Environmental Quality, Patrick Greiner, Julius Alexander Mcgee

Urban Studies and Planning Faculty Publications and Presentations

The authors examine the effect of a country’s placement in the world system in 1960 on its ability to use wealth to mitigate environmental impacts. They use random-coefficients models to examine if countries belonging to core, semiperiphery, and periphery categories are able to use growth in gross domestic product (GDP) per capita to reduce CO2 emissions per capita. The findings indicate that core nations have an attenuated relationship between GDP per capita and carbon dioxide emissions per capita at higher levels of economic activity. However, nations in the semiperiphery have a relationship between GDP per capita and CO2 per capita …

Moving Mountains : A Study Examining Long-Term Impacts Of Mountaintop Removal Coal Mining On Mortality In The Appalachian Region Using Geographic Information Sciences Techniques., James Howard Kent Pugh

Electronic Theses and Dissertations

Over the last hundred years, the Appalachian region has been dominated by the coal industry. It has also been and currently is one of the unhealthiest regions in the United States. Recent scholarship has examined the relationship between coal mining and health and mortality rates in the Appalachian region. The first study incorporates air quality and pollution data to examine if coal mining counties have higher levels of pollution and if this pollution contributes to mortality disadvantage. In the second study, I construct a population-based coal-exposure measure to better evaluate the relationship between coal mining and health I find that …

Suicide Prevention: Do San Francisco Afsp Community Walks Reduce Hopelessness?, Tyson Peltz

Master's Projects

Community-based outreach programs have been found to be effective, helping to educate people, and reduce suicide through outreach and peer group support. The American Foundation for Suicide Prevention (AFSP) has been at the forefront of the battle to reduce suicide through education, fund raising, lobbing, and support efforts to those in need of suicide prevention services, as well as those who have lost someone. One of the ways they have done this is through community walks and fundraising throughout the nation for anyone affected by suicide. These events are called Out of the Darkness Walks, which allow the community to …

Evaluating Social Network Dynamics Of Bigg’S Killer Whales (Orcinus Orca) And Vessel Traffic Within A Transboundary Region: Implications For Conservation Management, Courtney Smith

Dissertations

The social lives of animals are defined by group dynamics based on the nature and strength of associations and movements between individuals, often resulting in highly complex and interconnected social networks. However, understanding of how environmental variables may shape this structure is poorly understood. Within the inland waters of Washington State and southern Vancouver Island, British Columbia, mammal-eating Bigg’s (transient) killer whales occur in relatively small, but stable social groups. Group size and occurrence in recent years has increased, coinciding with a growing whale watching industry. Given the central importance of the social network within killer whale population dynamics, such …

Language And Socioeconomics Predict Geographic Variation In Peer Review Outcomes At An Ecology Journal, C. Sean Burns, Charles W. Fox

Information Science Faculty Publications

Papers submitted by scientists located in western nations generally fare better in the peer review process than do papers submitted by scientists from elsewhere. This paper examines geographic variation in peer review outcomes (whether a manuscript is sent for review, review scores obtained, and final decisions by editors) for 3529 submissions over a 4.5 year period at the journal Functional Ecology. In particular, we test whether geographic variation in language and socioeconomics are adequate to explain most or are all of this variation. There was no relationship between the geographic regions of handling editors and the decisions to send …

Uneven Urban Metabolisms: Toward An Integrative (Ex)Urban Political Ecology Of Sustainability In And Around The City, Innisfree Mckinnon, Patrick T. Hurley, Colleen C. Myles, Megan Maccaroni, Trina Filan

Environment and Sustainability Faculty Publications

Expanding cities present a sustainability challenge, as the uneven proliferation of hybrid landscape types becomes a major feature of 21^st century urbanization. To fully address this challenge, scholars must consider the broad range of land uses that being produced beyond the urban core and how land use patterns in one location may be tied to patterns in other locations. Diverse threads within political ecology provide useful insights into the dynamics that produce uneven urbanization. Specifically, urban political ecology (UPE) details how economic power influences the development decision-making that proliferate urban forms, patterns of uneven access, and modes of decision-making, …

Water quality and access is under grave threat in Ecuador, yet remains poorly studied. Macroinvertebrates were used as biological indicators to study water quality around Reserva Natural Madrigal del Podocarpus, Loja Province, Ecuador. Data on macroinvertebrates was combined with hydrologic measurements of stream functions. Macroinvertebrate sampling was conducted from 6 sites within the Upper Río Zamora watershed. Geologic outcrops were observed along several roadcuts and stream banks. Hydrologic data was collected by measuring discharge, elevation change, and finding the highest permanent spring. The EPT index (number of EPT individuals and percentage of EPT individuals) and the BMWP/Colombia Index for macroinvertebrates …

Hiv Harm Reduction Methods: A Comparison Between Switzerland And The United States, Erin Major

Independent Study Project (ISP) Collection

This paper explores the connections between harm reduction methods and the prevalence of HIV/AIDS in Switzerland and the United States of America, focusing primarily on the harm reduction methods of needle exchange programs, safe drug consumption spaces, and sex education. While these two countries are largely similar in their culture and geopolitical approaches, there are some key differences in how HIV is approached in each. Switzerland’s somewhat unique approach with relaxed drug policies and more pragmatic, harm reduction based response to the AIDS epidemic sets a model framework for other countries to follow, with comparatively widespread use of needle exchange …

An Unparalleled Opportunity For An Important Ecological Study, L. David Mech, Shannon M. Barber-Meyer, Juan Carlos Blanco, Luigi Boitani, Ludwig Carbyn, Glenn Delgiudice, Steven H. Fritts, Djuro Huber, Olof Liberg, Brent Patterson, Richard R. Thiel

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

Wolves (Canis lupus) and moose (Alces americanus) have been studied since 1958 on 540-squarekilometer Isle Royale National Park, in Lake Superior. Wolves arrived there across the ice around 1949, and the population once increased to about 50, averaging about 25 annually (Mech 1966, Jordan et al. 1967, Vucetich and Peterson 2009). However, for various reasons, wolf numbers there have now dwindled to 2 nonbreeders, and the US National Park Service has proposed reintroducing 20–30 wolves over 3 years (National Park Service 2016). This situation offers an unparalleled opportunity to promote science-based management of this unique national park. …

Does Detection Range Matter For Inferring Social Networks In A Benthic Shark Using Acoustic Telemetry?, Johann Mourier, Nathan Charles Bass, Tristan L. Guttridge, Joanna Day, Culum Brown

Social Behavior Collection

Accurately estimating contacts between animals can be critical in ecological studies such as examining social structure, predator–prey interactions or transmission of information and disease. While biotelemetry has been used successfully for such studies in terrestrial systems, it is still under development in the aquatic environment. Acoustic telemetry represents an attractive tool to investigate spatio-temporal behaviour of marine fish and has recently been suggested for monitoring underwater animal interactions. To evaluate the effectiveness of acoustic telemetry in recording interindividual contacts, we compared co-occurrence matrices deduced from three types of acoustic receivers varying in detection range in a benthic shark species. Our …

Information In The Ecosystem: Against The “Information Ecosystem”, Timothy B. Norris, Todd Suomela

Copyright, Fair Use, Scholarly Communication, etc.

The “information ecosystem” metaphor is widely used in academic libraries and has become nearly ubiquitous when speaking of the information systems that support scholarly communication and varied forms of data sharing and publication. The trending use of this language arises from non-academic applications — for example in big data (the Hadoop ecosystem) or software development (the node.js ecosystem) — and there remains little critical examination of the use of this metaphor. Indeed, the definition of ecosystem as the set of relations between living organisms and their surrounding non-living environment is apparently not directly a part of the metaphor. This paper …

Political Science & International Studies: Faculty Publications

In recent decades, the rise violent phenomena in Brazil has reached epidemic proportions. However, the prevalence of domestic violence (DV) across different states in the country is not well established. The objective of this study was to describe the distribution of DV across Brazilian states from 2009 to 2014. An ecological study based on spatial analysis techniques was performed using Brazilian states as geographical units of analysis. A multilevel Poisson model was used to explain the risk of DV in Brazil according to age, sex, period (fixed effects), the Human Developing Index, and the victim’s residence state (random effects). The …

Examination Of Multidimensional Acculturation Theory And Acculturation Process On Latinas/Os In Communal Recovery Homes, Roberto Lopez Tamayo

College of Science and Health Theses and Dissertations

Disparities in access and utilization of substance abuse treatment (SAT) among Latinas/os, accentuated by the rapid growth of this population are creating a public health issue. Among those in need of SAT, only 7.7% receive treatment and nearly half of these individuals complete SAT or continue their recovery in a controlled environment. Additionally, Latinas/os who complete SAT reported their needs were not met in treatment. Although substance abuse literature has given more consideration to environmental factors and social support in relation to treatment outcomes, current substance abuse models fail to address important contextual and cultural aspects for Latinas/os in recovery. …

IMPORTANCE: Analysis of geospatial variation in acute bronchitis due to socioeconomic and environmental factors can allow the efficient delivery of resources to populations most at risk.

OBJECTIVE: We sought to determine if small scale variation in socioeconomic factors and emergency room (ER) visits for acute bronchitis are associated in small cities or rural communities. We also modeled the effects of air quality on daily rates of ER visits for acute bronchitis in the context of socioeconomic factors to investigate modifying relationships.

DESIGN, SETTING, AND PARTICIPANTS: We examined ER visits for acute bronchitis in San Luis Obispo and Santa Barbara counties …

Obamacare And The Fight Against Income Inequality, Perry T. Mindo Jr

Undergraduate Economic Review

In this paper, we analyze the Affordable Care Act to determine the magnitude and significance of its effects on income inequality in America. Specifically, we find that the ACA decreased the Gini coefficient by 0.67% and reduced the share of income held by the top 20 percent of income earners by 0.67% over the time period of our study. Furthermore, we estimate that the ACA accounts for a redistribution of approximately $13 billion from the top 20 percent of income earners to the bottom 80 percent of income earners.

Can Big Whales Inspire Big Behaviors? A Study Of Environmental Communication, And Nature Immersion, Theresa Soley

Master's Theses (2009 -)

Direct contact with wild nature is becoming harder for people to access in present times, yet research suggests that experiencing nature is important to the formation of environmental values, which may lead to conservation behaviors. My thesis experiment theorizes that direct contact with nature has the ability to impact people's behavioral beliefs and intentions toward the environment, applying Icek Ajzen's Theory of Planned Behavior (TPB) and the New Ecological Paradigm Scale as measures. A questionnaire was administered post-whale watching trips in Juneau, Alaska to determine whether whales, direct experience with charismatic megafauna, could stimulate positive attitudes and behaviors toward recycling. …

Implementing Multilevel Food And Nutrition Security Frameworks In Sub-Saharan Africa: Challenges And Opportunities For Scaling Up Pulses In Ethiopia (A Research Note), Lisa F. Clark

Journal of Rural Social Sciences

Increasingly, there is global consensus that pulse crops can help address ongoing nutrition and food security challenges in sub-Saharan Africa. Evidence shows that scaling-up production and consumption of pulses grown in sub-Saharan Africa has the potential to make positive contributions to socioeconomic and environmental sustainability. By taking a systems approach to analyze policy documents and stakeholder reports on food and nutrition security, this article argues that policy asymmetries within multilevel governance frameworks challenge efforts to scale-up existing pulse value chains in this region, specifically Ethiopia. It demonstrates that policy sectoralization and siloing between the nutrition and agriculture agendas contribute to …

Effects Of An Early Life Immune Challenge On Body Growth, Personality, Mating Behaviors, And Brain Development Of Zebra Finches (Taeniopygia Guttata), Ahmet Kerim Uysal

USF Tampa Graduate Theses and Dissertations

The developmental stress hypothesis predicts that an aversive condition, such as decreased food intake, predation, and social isolation, in the early developmental stage could have long term effects on behaviors and brain development of an animal. In nature, bird nestlings are susceptible to various factors, such as malnutrition, infections, and parasites. Effects of early life stress on adulthood have been extensively studied with some stressors including malnutrition. However, immune challenges as an early life stressor and their long-term programming effects on adult behaviors are yet to be studied in detail. The goal of the current study was to investigate changes …

Library And Information Services To The Visually Impaired Persons, Junaid Rayini

Library Philosophy and Practice (e-journal)

Visually impaired people have the same information needs as sighted people. Just as sighted people might read a newspaper, listen to a CD or download electronic information from the Internet; visually impaired people also want access to relevant information in their chosen accessible format. Developing an efficient library service for print-disabled people is extremely important, because there are significantly fewer books available commercially in accessible formats compared to what is published in print for the general public. Libraries have a moral obligation to make information available to all categories of users regardless of their gender, age, race, political affiliation or …

Sociology

Objective: Lower body mass index (BMI) and higher dietary quality reduce the risk of colorectal cancer (CRC). A full understanding of how these associations vary by sex and weight is lacking. Methods: We used data from the National Institutes of Health - American Association of Retired Persons (NIH)-AARP) Diet and Health Study for 398 458 persons who were 50-71 years old in 1995-1996 and followed through 2006. Exposures were dietary quality as reflected by the Mediterranean Diet, the Healthy Eating Index-2010 and the Dietary Approaches to Stop Hypertension score, stratified by BMI category. The outcome was CRC diagnosis from cancer …

Incorporating Place And Space: A Hierarchical Spatial Approach To Exploring Preventable Congestive Heart Failure Hospitalizations In New York City, Rachael Weiss Riley

Dissertations and Theses

Background: Faced with rising medical care costs, increasing prevalence, and widening health disparities, preventing congestive heart failure (CHF) hospitalizations is a central public health concern. Despite evidence of geographical clustering in preventable CHF admissions, there is a lack of research designed to examine spatial patterning of CHF and the local area neighborhood determinants that contribute to this variability. This study sought to assess and evaluate the importance of both space and place in analyzing preventable CHF hospitalizations and readmissions by applying appropriate statistical techniques, clarifying the assumption inherent in each method, and interpreting the findings within the context of existing …

A Comparative History Of Resurrection Plants, John Charles Ryan

CLCWeb: Comparative Literature and Culture

In his article "A Comparative Literary History of Resurrection Plants" John Charles Ryan assembles a comparative history of resurrection plants through textual analysis of early botanical commentaries, herbal references, prose, poetry, and other sources. Resurrection plants include a diverse range of botanical species, typically of arid regions, that appear to come back to life after complete desiccation. Historical and contemporary observers—from sixteenth-century herbalist John Gerard to contemporary Australian poet John Kinsella—have expressed an abiding fascination for resurrection plants' capacity to survive harsh environmental conditions. The plants court their own deaths by paring down—then restoring—physiological processes in relation to shifting ecological …

The Impact Of The Medieval Climatic Anomaly On The Archaeology At Edwards Air Force Base, Jessica Amanda Porter-Rodriguez

Electronic Theses, Projects, and Dissertations

A series of severe and prolonged droughts occurred throughout the Northern Hemisphere between approximately 1150 BP to 600 BP. This phenomenon is referred to as the Medieval Climatic Anomaly and has been shown to have differentially impacted various regions of the world. Previous studies have suggested causal links between the Medieval Climatic Anomaly and observed culture change.

The goal of this study was to examine the Antelope Valley region of the Mojave Desert for evidence of impacts on human populations related to the Medieval Climatic Anomaly. To achieve this goal, a sample selection of archaeological sites was chosen from lands …

Hanoi Vietnam’S Peri-Urban Space And Its Impact On People’S Livelihoods, Collin V. Sumera

Sustainability and Social Justice

ABSTRACT

Hanoi Vietnam’s Peri-urban Space and Its Impact on People’s Livelihoods

Collin V. Sumera

Peri-urban is both a space and a process, yet there is no cookie cutter definition that may be applied to developing cities encountering this phenomenon. Each space is constructed differently, and each process has different actors. This paper examines the role that the Communist Party of Vietnam plays in the creation of peri-urban space in Hanoi, and how this space affects residential and former agricultural Land Use Right holder’s livelihood opportunities. The notion of the peri-urban space has not fully been developed for Hanoi, thus I …
