Enhancing The Visual Environment Of Indoor Housed Laboratory Cynomolgus Macaques (Macaca Fascicularis) To Reduce Stress And Maladaptive Behavior, Jeannine C. Rodgers

Theses and Dissertations

Nonhuman primates housed in indoor laboratory environments are generally exposed to nondescript background visual stimuli. This environment is not ideal for species whose primary sensory modality is visual. To provide a more naturalistic visual environment that would potentially improve their welfare, this study assessed the efficacy of a passive natural visual stimulus in the reduction of stress and stereotypy and agonistic behaviors in a cohort of four (2 male, 2 female) Cynomolgus macaques (Macaca fascicularis) housed in an indoor laboratory facility in New York City. The macaques were exposed to four different videos depicting scenes of natural landscapes that were …

The Effect Of The Lunar Cycle On The Demographics Of Asian Elephants Observed In Open Areas In A Protected Wildlife Sanctuary And Surrounding Crop Fields, Serene K. Rivera

Theses and Dissertations

Due to human development and habitat fragmentation, Asian elephants increasingly use human landscapes and encounter people. These interactions have led to negative interactions between humans and elephants, such as crop-raiding. Despite efforts to mitigate these conflicts, farmers have not been able to consistently protect their crops from elephant foraging. Therefore, it is important to understand elephant behavior in these landscapes to help create long term mitigation plans. Specifically, research regarding demographic patterns in Asian elephants’ perceived predation risk can inform wild elephant management. This study used camera traps in Salakpra Wildlife Sanctuary in Kanchanaburi, Thailand to observe the wild Asian …

Envelope Of Ruin : Material And Spatial Responses Of New York City Homeless To The Covid-19 Pandemic, Kyle C. Maxey

Theses and Dissertations

This paper attempts to understand human material responses to catastrophic urban collapse. Using Henri Lefebvre's theories of spatial production and the history of a section of the Brooklyn-Queens Expressway (BQE) this paper develops a theoretical framework for understanding the dynamics present in the creation of an urban ruin. Through the observation of homeless material responses, particularly the construction of encampments under the BQE, during the COVID-19 pandemic "lock-down" in New York City, this thesis illustrates how populations respond to urban ruin and social collapse. Moving forward, this paper hopes to serve as a synthesis of urban theory and archeological observation …

Electrifying Choices: Decoding Electric Vehicle Adoption And Policy Incentives In America, William T. Ball

Theses and Dissertations

Countries, states, and municipalities are working to reduce greenhouse gas emissions in the transportation sector by leveraging policy incentives to promote electric vehicle (EV) adoption. I study the efficacy of state-level time-of-purchase rebate incentives in the United States between 2016 and 2022, and employ a generalized difference-in-difference two-way fixed effects model that enables causal inference. I find that EV rebate incentives cause an increase of 1 EV per 1,000 vehicles. EV rebate incentives also cause a decrease in gasoline powered vehicles by 3 vehicles per 1,000, and a decrease in diesel powered vehicles by 1 per 1,000. EV rebate incentives …

Subspace Decomposition Of Linear Secrecy Codes, David Robert Joseph Hunn

Theses and Dissertations

We introduce a new method for the study of linear codes, termed subspace decomposition, which provides new insights into code structure and performance. Briefly, subspace decomposition comprises the evaluation of complex properties of a linear code by evaluating simple properties of its constituent subspaces. We find that this technique has application to a number of problems in coding theory. When applied to the problem of evaluating the performance of secrecy codes, subspace decomposition provides an efficient method for computing the equivocation of coset codes over the binary erasure wiretap channel. It is also especially efficient in computing the chi squared …

Reconfigurable Over-The-Air Chamber: Measuring Radio Frequency Device Performance, Benjamin T. Arnold

Theses and Dissertations

Over-the-air (OTA) testing is particularly useful in determining the performance of multi-antenna communication devices in real-world environments. Traditional OTA testing technologies include the reverberation chamber (RC) and the multi-probe anechoic chamber. More recently, the reconfigurable OTA chamber (ROTAC), which is a RC that has probes lining its chamber walls, has been proposed. These probes are either driven with a source, possibly combined with a channel emulator, or are terminated with a tunable impedance. Controlling the excitations and terminations on the probes can alter the fields within the chamber and thereby synthesize an antenna response at the device under test (DUT). …

Enumeration Of Level-K Hypertriangulations, Patrick J. Kaylor

Theses and Dissertations

Triangulations are a classical object in discrete and computational geometry that finds it uses in many other fields, including numerous applications. In this thesis we approach the question of enumerating all hypertriangulations of a point set, the family of tilings introduced by Olarte and Santos in 2022 as induced projections of hypersimplices. Unfortunately, the usual approach to enumeration of trinagulations using flips may not work for hypertriangulations as flip-connectivity is only conjectured for that family even in the two-dimensional case. As a result, we develop a DFS-based algorithm and present its Python implementation that enumerates all hypertriangulations of small point …

Examining Tele-Mental Health Utilization In North American Indigenous Communities, Elleh A. Driscoll

Theses and Dissertations

Tele-mental health delivery reported by clinicians in Indigenous communities before, during, and after the pandemic has largely remained unexplored across psychology literature. Tele-mental health (TMH) is the utilization of technology tools to communicate and treat clients (Riding-Malon, 2014). TMH (i.e. mental health services accessed via zoom, telephone, etc.) is associated in recent research with effective rates for mental health care treatment comparable to in-person rates for both immediate and long-term outcomes (McCord, 2020; Lin, 2021). The current study examined self-reported mental health clinicians (n=104) serving North American Indigenous clients on a variety of TMH factors during and after the COVID-19 …

Examining Mental Health Professionals' Attitudes Towards Individuals With Rural Accents, Emily Heavner

Theses and Dissertations

Bias against people from rural areas is ingrained in American culture, and stereotypes that people from rural regions are backwards, uneducated, and unintelligent are prevalent (Fulkerson & Thomas, 2016; Hartman et al., 2023; Howley, 2009; Shirley, 2010). Many people from rural areas have accents that mark them as coming from a rural region (Flanigan, 2000). Research suggests that accent is a reminder that the speaker is from a different cultural group than the listener, triggering biases and stereotypes about the speaker (Chakraborty, 2017). Because accent and rural culture are not often discussed as part of multicultural competence, many mental health …
