Exploring The Effectiveness Of Ecological Momentary Assessment And Video At Eliciting The Impact Of Park Features On Human Health And Well-Being In A Protected Area Context, Katelyn O'Bright

Theses and Dissertations (Comprehensive)

It is increasingly recognized that contact with nature in parks and other forms of protected areas provides benefits to visitors’ physical, mental, social, spiritual, and intellectual health and well-being. However, the methods used to assess these outcomes, including the influence of different environmental features that lead to these benefits, is under-researched. To address this gap, this study used a mixed methods design to explore the effectiveness of using Ecological Momentary Assessment (EMA) and video to assess the impact of various park features on the self-perceived (subjective) health and well-being of visitors. Participants were prompted by a mobile application on their …

“Bright Spots” And Effectively Communicating The Ecological And Social Outcomes Of Protected And Conserved Areas In Canada, Jen Hoesen

Theses and Dissertations (Comprehensive)

Healthy and resilient protected and conserved areas are the foundation of biodiversity conservation, improve livelihoods, and drive sustainable development. Protected lands and seascapes radiate life sustaining ecosystem services and provide important places for nature connection, rejuvenation, and inspiration. Although escalating human pressures and climate change-related risks continue to place many protected and conserved areas under increasing threat, “conservation bright spots” have emerged as a key communications strategy to illustrate where and how biodiversity and the social benefits it provides is performing relatively well. Given the crucial need to educate the public about biodiversity-related issues and amplify solution-centric approaches to support …

Nitrogen: Both A Potential Stimulator And Suppressor Of Cyanobacterial Blooms In Temperate Lakes, Catherine Goltz

Theses and Dissertations (Comprehensive)

Cyanobacterial blooms are complex phenomenon that are impacted and controlled by various factors such as lake depth, air temperature, wind, and nutrient loading. Nutrients such as phosphorus, nitrogen and iron all have very differing effects on cyanobacterial blooms. While phosphorus and iron are known to drive cyanobacterial biomass, nitrogen has been observed to have a direct impact on toxin synthesis. Nitrogen exists in the environment in many different forms such as atmospheric N₂, in inorganic forms such as nitrate and ammonium as well as in organic forms such as urea which can all affect cyanobacterial bloom development differently. …

A Machine Learning Approach To Classify Open Water And Ice Cover On Slave River Delta, Ida Moalemi

Theses and Dissertations (Comprehensive)

Seasonal temperature trend and ice phenology in Great Slave lake (GSL), are strongly influenced by warmer inflow from Slave river. The Slave river flows to GSL through Slave river delta (SRD), bringing a rise in temperature that triggers the ice break-up process of the lake. Slave river discharge is subject to multiple stressors including climate warming and upstream water activities, which in turn, directly affects the GSL break-up process. Consequently, monitoring the break-up process at SRD, where the river connects to the lake, serves as an indicator to better understand the cascading effects on GSL ice break-up. This research aims …

The Journey “Box” first asks preservice teachers to explore themes by reading children’s literature and then positions preservice teachers as interviewers as they seek out different facets of their family’s historical narrative from members of their family. Preservice teachers then use their experience with a Journey “Box” to design an inquiry that could be used in their field experience. The Journey “Box” integrates social studies standards and best practices with ELA standards.

Floral And Genetic Divergence Across Environmental Gradients Is Moderated By Inter-Population Gene Flow In Platanthera Dilatata (Orchidaceae), Lisa E. Wallace, Marlin L. Bowles

Biological Sciences Faculty Publications

Understanding how natural selection acts on intraspecific variation to bring about phenotypic divergence is critical to understanding processes of evolutionary diversification. The orchid family is well known for pollinator-mediated selection of floral phenotypes operating among species and along environmental or geographic gradients. Its effectiveness at small spatial scales is less understood, making the geographic scale at which intraspecific floral variation is examined important to evaluating causes of phenotypic divergence. In this study, we quantified phenotypic variation in the orchid Platanthera dilatata across 26 populations in coastal Southeast Alaska and compared this to edaphic and genetic variation at microsatellite loci. We …

Entomology and Plant Pathology Faculty Publications and Presentations

The lone star tick, Amblyomma americanum, is the predominant human-biting tick in Arkansas and a vector of multiple pathogens of medical and veterinary importance. Increasing concerns over acaricide resistance and environmental contamination have prompted evaluation of alternative control strategies. We assessed the pathogenicity of a native Arkansas isolate of Metarhizium robertsii (Savoy P10N1) against laboratory-reared adult and nymphal A. americanum under controlled conditions. Ticks were immersed in a conidial suspension (1 × 10⁸ conidia/ml) and monitored for mortality and fungal sporulation for 77 days post-inoculation. Cumulative mortality followed a time-dependent logistic pattern, with significant fungal-induced mortality beginning at 14 …

Obfuscating Systemic Racism: A Critical Policy Discourse Analysis On The Operation Of Neoliberal Ideas In Media Representation Of A School District State Takeover, Trish A. Lopez, Holly Sheppard Riesco, Christian Z. Goering

Curriculum and Instruction Faculty Publications and Presentations

Education reform in the United States has unwisely focused attention on standards and accountability to the state as determined by standardized testing (Berliner & Biddle, 1995; Mehta, 2013). Stemming from the emphasis on standards-based accountability are the ideas of rapid school turnaround and the state’s role in this process (Peck & Reitzug, 2014; VanGronigen & Meyers, 2019). The current study employed critical policy discourse analysis to examine the media’s portrayal of the 2019 determination to continue or terminate state control of the Little Rock School District.

With the assistance of advanced computing, statistical and spatial methods, GSM data …

Outlier State: Elite Rhetoric As A Window To Western Australian Regionalism, David Jones

Theses

Western Australia was the last of the Australian self-governing British colonies to agree to join the Australian Federation in 1900 and voted to secede, by a significant electoral margin, in a referendum held in 1933. Some have even argued the State has been a reluctant member of the Federation since this momentous vote. If this is the case, what evidence is there that can justify this perception, and possibly point to enduring underlying factors supporting this Western Australian regionalism sentiment and identity? Many of the drivers which led to the successful secession referendum in 1933 still exist today. The State …

Exposing Endo: Labor Abuse And Exploitation On Contractual Workers In The Philippines, Olivia M. Fisher

Pell Scholars and Senior Theses

Article 281 states that workers must be put on a probationary period for 6 months of employment before receiving benefits. ENDO-contracting is the situation where corporations hire workers on 5 to 6-month contracts to avoid paying their workers benefits. This research will be conducted using qualitative data from past research publications, court cases, and interviewing anti-ENDO advocates. The historical summary will explain the origins of this law and how it has progressed into common labor practice. ENDO- contracting disproportionately affects the low-wage workforce and deprives them of regular employee benefits. The lack of these benefits has created poor working conditions …

Adaptation Rationales And Benefits: A Foundation For Understanding Adaptation Impact, Edward R. Carr, Johanna Nalau

Geography

Efforts to achieve coordinated, effective, and impactful adaptation outcomes are complicated by factors ranging from the local specificity of adaptation needs to the challenges of politics and prioritization that drive funding decisions. However, these and other challenges are perpetuated and exacerbated by poorly constructed, often implicit, and generally institution- or context-specific impact pathways connecting policy/institutional priorities through their materialization in specific actions to their intended outcomes. We call these impact pathways adaptation rationales, as they represent the logic of an adaptation action. The implicit nature of most current adaptation rationales makes it difficult to identify and test the accuracy and …

Four Fundamental Questions To Evaluate Land Change Models With An Illustration Of A Cellular Automata–Markov Model, Cláudia M. Viana, Robert Gilmore Pontius, Jorge Rocha

Geography

Numerous models exist for users to simulate land change to communicate with an audience concerning future land change. This article raises four fundamental questions to help model users decide whether to use any model: (1) Can the user understand the model? (2) Can the audience understand the model? (3) Can the user control the model? (4) Does the model address the goals of the specific application? This article applies these questions to the popular cellular automata–Markov (CA–Markov) model as IDRISI’s CA–Markov module expresses. Sensitivity analysis examines 120 ways to set the module’s parameters. Verification compares the module’s behavior to the …

Spectres Of Women In Wuthering Heights, Corinne H. Shearer

Dissertations and Theses

Central to Emily Brontë’s Wuthering Heights (1847) is its famous haunting scene. As this paper suggests, it is in the haunting scene that the novel’s themes are at their most potent and where Brontë is at her most daring, challenging the socially prescribed, gendered binaries of her time. The primary interest of this paper is in describing the particular power of Brontë’s feminine ghost, an archetypal figure of the female Gothic, using theoretical frameworks from poststructuralism and psychoanalysis. I propose a feminist interpretation of the novel which emphasizes the catalyzing effect of the haunting scene and its reversals– and which …
