Assistive Technologies Used In Canadian University Libraries For The Visually Impaired, Ramina Mukundan, Nikesh Narayanan

Library Philosophy and Practice (e-journal)

Information has always been a catalyst for societal improvements. Libraries play a crucial role in ensuring equitable access to information resources. Enhanced accessibility helps in establishing an atmosphere that supports and promotes inclusive education. Information and resource access is quite a challenge for visually impaired people. The needs of people with varying levels of visual impairment differ in their range and magnitude. The use of assistive technologies greatly aids in closing this gap. Resource and accessibility provisions should be modified to meet the needs of visually impaired users, who need specialized equipment to access traditional and modern technology-based information resources. …

Citizens' Preferences On Green Infrastructure Practices And Their Enhancement In Portland, Oregon, Katsuya Tanaka, Hal T. Nelson, Nicholas Mccullar, Nishant Parulekar

Public Administration Faculty Publications and Presentations

Green infrastructure (GI) has been gaining increasing attention due to its efficiency in controlling and purifying urban stormwater runoff, creating environmental amenities, and biodiversity conservation. Nevertheless, the existing knowledge of people's preferences for GI is not yet sufficient for evidence-based policymaking for enhancing GI. This study analyzes citizens' perceptions of the relative importance of six GI practices and estimates their willingness to pay (WTP) to enhance them. To this end, the study applies two types of stated preference methods (best-worst scaling and contingent valuation) to citizen survey data collected in Portland, Oregon. We found that GI practices that are more …

As a result, the PSBB policy had a …

"We've Created Cheap Energy Off The Backs Of Salmon": Dam Removal Politics And Alliances In The Lower Snake River Basin, Krista Harrington

Dissertations and Theses

Dams, once considered by many to be good for water development in the Western U.S., might not be a part of a climate resilient future. Dams have come under increasing scrutiny due to undesirable ecological implications. Although dam removal proposals are growingly popular in recent decades, they are controversial since they impact different stakeholders in different ways. In the Pacific Northwest, the Lower four Snake River dams have long been criticized for their negative impacts on salmon. In February 2021, US Congressman Mike Simpson (R-Idaho) proposed a comprehensive framework to deconstruct the Lower four Snake River dams as an attempt …

The Modern-Day Effect Of Holc Redlining On Neighborhood Development, Liubov Ivashov

Master's Theses

Racial segregation, which happened more than one hundred years ago in the U.S., is a fundamental cause of economic inequality for people living in historically segregated neighborhoods today. Redlining was one form of federal policy that forced to separate communities by race even more after the Great Depression. The Home Owners Loan Corporation (HOLC) maps are widely used in economic research papers as one of the most comprehensive sources of data available to measure the effect of residential segregation. In this paper, using the Historical Redline Score (HRS) method, the author measured the association between modern-day population distribution, rent prices, …

This research has been conducted deductively, as it will use the theories mentioned in the literature review to define hypotheses.

Gangs are known for their violent and disruptive behavior. They ravage community resources and introduce …

The Interaction Between Anxiety Sensitivity And Sleep Disturbance In Relation To Alcohol Use Among Adolescents, Gabrielle Meshell Armstrong

Honors Theses

Both substance use and sleep disturbance are common in adolescence. Additionally, alcohol use specifically is positively associated with a number of sleep disturbances. However, little to no research has examined factors that may influence the relation between problematic alcohol use and sleep disturbances among adolescents or adults. One factor that may be particularly important to consider in this regard is anxiety sensitivity (AS; i.e., the tendency to interpret unpleasant physiological sensations as dangerous). Among previous studies, anxiety sensitivity has been found associated with both increased alcohol consumption and sleep disturbances. The current study evaluated the main and interactive effects of …

County Social Isolation And Opioid Use Disorder Among Older Adults: A Longitudinal Analysis Of Medicare Data, 2013–2018, Tse-Chuan Yang, Carla Shoff, Seulki Kim, Benjamin A. Shaw

Department of Sociology: Faculty Publications

This study aims to fill three knowledge gaps: (1) unclear role of ecological factors in shaping older adults’ risk of opioid use disorder (OUD), (2) a lack of longitudinal perspective in OUD research among older adults, and (3) underexplored racial/ethnic differences in the determinants of OUD in older populations. This study estimates the effects of county-level social isolation, concentrated disadvantage, and income inequality on older adults’ risk of OUD using longitudinal data analysis. We merged the 2013–2018 Medicare population (aged 65+) data to the American Community Survey 5-year county-level estimates to create a person-year dataset (N = 47,291,217 person-years) and …

A Meta-Analysis Of Quantitative Collecting Techniques For Spiders, Eliana Eldridge, Joshua Hicks, Sean O'Keefe

2022 Celebration of Student Scholarship - Poster Presentations

Quantitative sampling of organisms is often used to provide information in ecological studies, monitor populations, and aid in biodiversity projects. Many studies involve the quantitative sampling of spiders. In this meta-analysis study, 207 peer-reviewed journal articles formed the basis of an initial data set for a quantitative analysis of spider collection techniques. Data collected included country of study, mode of study, trapping techniques used, spider diversity, and number of specimens collected. Our meta-analysis gathered research articles that included 33 different countries of study. Trapping techniques greatly vary depending on the habitat in which spiders dwell. These were divided into aerial, …

The Correlation Between Vaccine Hesitancy And Privilege: Exploring The Degree To Which Education And Income Foster Resistance To Vaccination Efforts, Sophie Goldenberg

Independent Study Project (ISP) Collection

Vaccine hesitancy is a public health issue of growing concern. Extensive pre-existing literature offers several explanations and conflicting viewpoints regarding reluctance toward vaccinations. However, minimal research has been done exploring the upstream social determinants driving vaccine hesitancy. Utilizing academic and gray literature and interviews with experts in the field, this study addresses this gap in knowledge with the research question: To what extent does privilege impact vaccine hesitancy and resistance? Vaccine hesitancy appears globally and is particularly concerning given the re-emergence of vaccine-preventable diseases (VPDs). Additionally, due to inconsistent causes, vaccine hesitancy is difficult to combat. In referencing the history …

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Fire incident has a great impact on the loss of lives and financial loss due to property damage. Areas with high population density, densely physical building conditions, and irregular building patterns commonly form congested residential slum areas are vulnerable to fire hazards. The capital city of Jakarta is the most populous city in Indonesia and the most densely populated city, with an average of 15,900 people per sq km. In 2019, there was 2,109 fire incident recorded, and nearly 20% of them occurred within the West Jakarta Municipality area. This study investigates the relationship of population density and building density, …

The North ‘Helicoptering’ Into The South: A Meta-Analysis Of Parachute Science In Ecological Field Studies, Alexandros Economou-Garcia

Student Publications

Science is increasingly collaborative, but scientists from the Global North (GN) often fail to collaborate with local scientists or to build local scientific capacity when conducting research in the Global South (GS). This practice is known as “parachute science” or “helicopter science”. In addition to ethical concerns, this practice is problematic in the field of ecology because it may reduce the likelihood that the research will inform local resource management and science policy. I hypothesized that, because research has become increasingly collaborative, there would be a decline in parachute science over time. In addition, I hypothesized that papers that included …

Sacred Scavengers: Vulture Conservation In Nepal, Hans Nedde

Independent Study Project (ISP) Collection

In the 1990s, a veterinary drug used to treat pain and disease in cattle nearly brought the nine vulture species of Nepal to extinction. In a span of 15 years, over 97% of vultures in Nepal perished. For the past 20 years, governments, organizations, and communities have been working together to save these vital scavengers from vanishing. From the lowlands to the Himalayas, vultures have been interacting with the environment and humans for millennia. This study explores the role that vultures play both ecologically and culturally in Nepal. It investigates vultures as a crucial ecological influence and how human action …

A Test Of Social Disorganization On Juvenile Property And Violent Crime Rates By Zip Codes Within Two Nonmetropolitan Counties, Mario T. Hesse, Susan M. Hilal

Great Plains Sociologist

This study tests the effects of social disorganization on juvenile crimes rates by zip code within two nonmetropolitan counties. It does so by examining the relationships between the selected social disorganization indicators of nontraditional family, residential mobility, and socioeconomic status (poverty) and violent and property crime among juveniles through the use of ANOVA testing. Secondary data obtained from the South Dakota Department of Corrections on adjudicated juveniles and their associated crime and residential location, as well as data from the United States Census Bureau is used and analyzed to test three main hypotheses. Findings indicate that areas characterized by poverty …

Classroom Ecology And Academic Performance: An Exploration Of The Merits Of The Single-Row Horseshoe Classroom Design, A. Olu Oyinlade, Silvana Maria Russo Watson

Great Plains Sociologist

Many studies on the effects of the traditional row-column classroom arrangement on academic performance have concluded that an action zone-whereby students who sit in the front and middle rows perform better than those seated at the sides and the back-exists. Therefore the traditional classroom arrangement does not provide learning parity for all students based on their seating positions, suggesting therefore, that some students are at a learning disadvantage due to seating position.

The present study investigated the single-row horseshoe design for its learning merits, with an attempt to discover if it offers a learning parity for all students or if …

County Walkability And Small Business Receipts, Talia Perluss

Scripps Senior Theses

This thesis explores the correlation between county walkability and small business receipts, as well as other possible demographic variables that could explain the success of small businesses, by using a fixed-effect panel regression model. Using county-level data in the years 2012 and 2017, this paper finds that there is a significant correlation between an increase in walkability and an increase in receipts. When running the fixed-effect regressions, this paper found that there is a moderately high positive correlation between walkability and per capita income, suggesting that the effects of an increase in walkability may also capture the effects of an …

A Hot Conflict Growing Ever Hotter: How Climate Change Provokes Instances Of Violence In South Sudan, Madison Menard

CMC Senior Theses

In South Sudan, people are not engaging in violent altercations because of climate change. People are not deciding to kill other people because the average temperature of the world has risen 1 degree celsius, or harming their neighbor because of irregular rain patterns. Alas the link from climate change to violence is not as direct as that. Rather, climate change has played a non-direct role in the South Sudanese conflict. Within the political marketplace it has subtly altered conditions which later spark or intensify outbreaks of violence. Climate change in this sense should be viewed as a stressor of sorts …

States' Public Health Funding And Population Health Outcomes: An Examination Through A Socio-Ecological Lens, Maureen K. Akubu-Odero

College of Graduate Studies: Theses & Dissertations

The US public health system has been underfunded for decades, despite its significant mandate of improving overall population health outcomes. This ecological study evaluates the association between state public health funding and population health outcomes and the role of state public health funding in reducing state-level health disparities. The findings show that the relationships between public health investments and improvements in health outcomes and health disparity in states are moderated by socioeconomic contextual factors. The findings suggest a need for continued and increased public health investments, tailored to community needs and context

Activity Levels Of Bat Species At Interstate Highway Sites With And Without Wildlife Underpasses In The Washington Cascades, Jenna Chapman

All Master's Theses

Roads force wildlife to navigate degraded and fragmented habitats across the globe, creating barriers to movement and increasing the risk of mortality. This includes bats, whose movements between foraging and roosting habitats may be impeded by roads. Wildlife crossing structures (WCS) are a common mitigation strategy to increase connectivity, but investigation into bat activity in and around these structures is limited. I investigated bat species presence and activity along Interstate-90 in the Cascade Range of Washington State. My goal was to test whether all bat species found in the nearby forest were also active along the highway, and whether bat …

Evaluation Of The Effect Of Culling On Browse Damage By The Japanese Serow In Gifu Prefecture, Japan, Shiori Ikushima, Naotoshi Kuninaga, Takashi Ikeda, Takuya Okamoto, Makoto Asano, Masatsugu Suzuki

Human–Wildlife Interactions

The Japanese serow (Capricornis crispus; serow) is a protected territorial ungulate native to Japan. However, locally overabundant serow populations can damage forest plantations and agriculture through browsing. Despite government permitted annual culling of serows on forest lands of Gifu Prefecture, Japan, browse damage continues to be reported in hinoki cypress (Chamaecyparis obtusa; cypress) plantations. Sika deer (Cervus nippon; deer), which are co-located with serows can also browse cypress, but their impacts have never been evaluated. The objective of our research was to evaluate the involvement of each species in browse damage and to establish …

Transformation Of Farmer Resistance In Conservation Areas: Land Occupation By Farmers In Mount Halimun-Salak National Park, West Java, Sulastri Sardjo, Arya Hadi Dharmawan, Dudung Darusman, Ekawati Sri Wahyuni

Masyarakat: Jurnal Sosiologi

A number of studies have shown various agrarian conflicts as a response by local farmers against the policy of national parks that prohibits them from accessing conservation forest areas. However, previous studies had not explained the dynamics of power relations between park authorities and farmers who stand in opposition to these policies. This study employs a qualitative research approach complemented by secondary data to explain the transformation of farmer resistance in the Mount Halimun-Salak National Park (TNGHS) area, namely from their repertoire of everyday resistance to practices of land occupation. Specifically, this study uses the “powercube” analytical framework to explain …

Cafos And Surface Water Quality: Evidence From Wisconsin, Zach Raff, Andrew G. Meyer

Economics Faculty Research and Publications

Concentrated Animal Feeding Operations (CAFOs) – animal feeding operations with over 1,000 animal units in confined spaces – have proliferated over the past 30 years in the United States. CAFOs provide operational cost savings, but higher animal concentrations in confined spaces can generate external costs, e.g., non-point source water pollution. In this study, we improve on previous research designs to estimate the relationship between the growth in CAFOs and surface water quality using longitudinal data on a large spatial scale. We use a panel dataset from 1995-2017 that links CAFO intensity with nearby surface water quality readings in Wisconsin to …

Seeding Resilience: An Examination Of The Impacts Of A Seed Saving Network In Western Montana, Christina Leas

Graduate Student Theses, Dissertations, & Professional Papers

Seed saving, a worldwide practice as old as agriculture, continues even in the context of an increasingly industrialized and globalized agricultural system. While some scholarship has focused on informal seed saving practices that continue to thrive in the global South, few studies have examined the dynamics of these practices in the global North, particularly in the American West. Informal seed saving systems have implications for the resilience of agroecosystems. The concept of resilience has become an important framework for conceptualizing agroecosystems as social-ecological systems, both in scholarship and in policy. However, operationalizing the concept of resilience, particularly in agroecology research, …

Lake Huron Shoreline Analysis, Shubham Satish Nandanwar

Theses and Dissertations (Comprehensive)

Lake Huron is a popular tourist destination and is home to several businesses and residents. Since the shoreline is dynamic and is subject to change over the years due to several factors such as a change in water level, soil type, human encroachment, etc., these locations tend to encounter floods due to increased water levels and wind speed. This causes erosion and loss to the properties along the shoreline.

This study is based on two areas of interest named Pinery Provincial Park and Sauble Beach which are located on the shoreline of Lake Huron where Pinery Provincial Park is a …

Exploring Scientists’ Perceptions Of Citizen Science For Public Engagement With Science, Stephanie A. Collins, Miriam Sullivan, Heather J. Bray

Research outputs 2022 to 2026

It is often assumed that citizen science is inherently participatory in nature. However, citizen science projects exist along a continuum from data contribution to full co-creation. We invited 19 biologists to explore their conceptions of citizen science. Almost all participants defined citizen science as involving non-scientists in data collection. This definition acted as a barrier for scientists who did not see how citizen science could suit their research objectives. While interviewees perceived many societal and experiential benefits of contributory citizen science, deliberate design is needed to realise the full potential of citizen science for public engagement

Community Perceptions And Aesthetic Valuation Of Remediation Gardens, Rachel Bechtold

Graduate Theses and Dissertations

Creating successfully remediated landscapes may rely on both natural resources and human perception in landscape design. Urban areas present a dynamic environment wherein communities and nature compete for resources and space. This dissertation study was designed to better understand aesthetic perceptions of native plants capable of land remediation in midwestern communities. Findings from this study show the importance of aesthetic perceptions of stakeholders towards rehabilitated landscapes and the importance of organizing indicators for future design decisions in an interdisciplinary fashion. Recommendations include continued evaluation of aesthetic perceptions for plant species in urban landscapes and modeling a more consistent framework for …
