Show more"Many applications demand the continued development of sensing systems that employ smart sensors, instrumentation circuits, and signal processing techniques to extract relevant information from real-world environments. In the engineering efforts to develop new sensors, tasks such as instrument automation, measurement process curation, real-time data acquisition, data analysis, and long-term tracking of inter-related datasets generate a significant volume and variety of information that is challenging to organize, record, and analyze. Sensor development and characterization experiments can be laborious, prone to human error, difficult to repeat precisely, and can produce data that are challenging to interpret. Such issues highlight a need for a structured, automated approach to curate measurement processes and data acquisition. This thesis presents the first software platform for i) digitally designing measurement recipes, ii) remotely scheduling and monitoring experiment execution, iii) automatic data acquisition, iv) analyzing and storing results datasets, and v) linking the datasets with their prospective meta-datasets for deeper analysis and inspection. The proposed platform is flexible and capable of managing a large set of diverse instruments, measurement recipes and sensor datasets. By employing several design abstractions, it allows users to remotely design, schedule, monitor and execute measurement-based experiments while archiving results along with their information-rich metadata therefore preserving the provenance of the datasets. The platform enable precise timing control of instruments and stimulus signals along with long-term tracking of datasets eliminating manual errors and human omissions thus enhancing research reproducibility and promoting knowledge discovery methodologies."--Page ii.

Show more"The current study integrates the construct of taboo into the organizational literature by considering its impact on coworker relationships, particularly in the context of authenticity and impression management. To explore how taboo topics may intrude on positive employee relationships, I consider its potential to impact helping behaviors in the workplace. An online between-subjects experiment manipulates motivation to be authentic or impression manage and a topic of discussion with a coworker to be taboo (e.g. abortion) or neutral (e.g. fitness). I evaluated participants' perceptions of their own motivation, participant's perceptions of their behavior during the interaction as authentic or impression management, and helping behaviors following the interaction. Results showed that motivation, but not taboo topics, influenced perceptions of behavior during the interaction. Further, taboo topics and the behavior during the interaction did not influence subsequent helping behaviors. However, exploratory results showed that taboo topics did impact affect towards the coworker that brought up the taboo topic. Limitations, implications for theory and practice, and future research directions are discussed."--Abstract.

Show moreIn fire debris analysis, analysts compare chromatograms of extracts of fire debris to a database containing chromatograms of ignitable liquid reference standards. Typically, the database will contain chromatograms of experimentally evaporated liquids. Unfortunately, experimentally evaporating ignitable liquids can be a time-consuming process. Previously, a mathematical model was developed with diesel that predicts the evaporation rate constant of compounds as a function of retention index (IT). The model can be used to generate predicted chromatograms of evaporated liquids. In comparing predicted to experimental chromatograms, predictive accuracy was high for comparisons using diesel, torch fuel, and marine fuel stabilizer.This research aims to improve the predictive accuracy of the model with respect to gasoline and to test the feasibility of developing correlation coefficient ranges for the classification of an ignitable liquid residue as gasoline. Improvement of the predictive accuracy of the model involved changes to the instrumental parameters and data analysis procedures. The feasibility of development of PPMC coefficient ranges involved comparisons of predicted reference collections of a non-gasoline ignitable liquid to chromatograms of experimentally evaporated gasoline.

Show moreDevelopment interventions mostly aim to ‘empower’ rural women by increasing their income and livelihood but rarely consider the voices of their beneficiaries. I study the meanings and experiences of empowerment or nari shakti as understood and described by rural women who lead self-help groups (SHGs) engaged in savings, micro-credit and income generation. I conducted the research in the central Himalayan region of rural India in Uttarakhand State using in-depth interviews with 11 SHG leaders. The findings indicate that the participants experience empowerment as solidarity and collective power that manifest in the form of self-reliance, courage, and independence. The participants associate their self-reliance with courage and inner strength which they have built as a means to survive the pain and struggle. Their stories of nari shakti are also stories of pain and struggle.This research implies the need to examine perspectives of feminists on empowerment related interventions. Further research is needed on how micro-credit SHGs help build collective action that can challenge patriarchal power structures and bring about social change. Such research can help provide solutions on how non-profits can utilize feminist strategies of consciousness raising while still meeting donor expectations for the SHG programs.

Show moreMajor technological advances are necessary to reach the goal of feeding our world’s growing population. To do this, there is an increasing demand within the agricultural field for rapid diagnostic tools to improve the efficiency of current methods in plant disease and DNA identification. The use of gold nanoparticles has emerged as a promising technology for a range of applications from smart agrochemical delivery systems to pathogen detection. In addition to this, advances in image classification analyses have allowed machine learning approaches to become more accessible to the agricultural field. Here we present the use of gold nanoparticles (AuNPs) for the detection of transgenic gene sequences in maize and the use of machine learning algorithms for the identification and classification of Fusarium spp. infected wheat seed. AuNPs show promise in their ability to diagnose the presence of transgenic insertions in DNA samples within 10 minutes through colorimetric response. Image-based analysis with the utilization of logistic regression, support vector machines, and k-nearest neighbors were able to accurately identify and differentiate healthy and diseased wheat kernels within the testing set at an accuracy of 95-98.8%. These technologies act as rapid tools to be used by plant breeders and pathologists to improve their ability to make selection decisions efficiently and objectively.

Show moreTelehealth services have increased substantially in the field of applied behavior analysis (ABA) since the start of the COVID-19 pandemic, though little research exists to empirically evaluate the efficacy of direct ABA telehealth treatment or more specifically, how behavior technicians can be trained to implement such treatment. The present investigation utilized a nonconcurrent multiple baseline design across participants to evaluate the use of an online behavioral skills training (BST) approach to teach behavior technicians to implement 20-min mand training sessions via telehealth with children diagnosed with autism spectrum disorder (ASD). The training phase of the study consisted of both role-play with feedback as well as feedback during sessions with the child participant. Results showed increases in behavior technician’s percentage of accurate implementation and rate of fully correct trials implemented following the training. Child participants also showed increased rates of independent mands following the BST implementation. Thus, BST may be an effective approach to teach behavior technicians to deliver mand training via telehealth.

Show moreDomesticated potato (Solanum tuberosum L.) is the world’s third most important food crop and is a food security crop according to the Food and Agriculture Organization of the United Nations. Currently, commercial potatoes are autotetraploid and mainly produced via asexual clonal propagation. The autotetraploid nature of most cultivated potatoes in combination with acute inbreeding depression when self-fertilized over multiple generations cause challenges in making advances with traditional breeding schemes. The benefits of moving potato to a diploid breeding model include a simplified breeding scheme, easier fixation of desirable alleles, and generation of inbred lines that may be used to generate F1 hybrids with heterotic potential. A major hinderance to self-compatibility originates from the gametophytic self-incompatibility (GSI) system in which the S-RNase and HT-B genes play a critical role. Utilizing CRISPR-Cas9 gene editing, HT-B and HT-B + S-RNase knockout (KO) lines were produced. HT-B KOs produced parthenocarpic fruit but remained self-incompatible. However, the S-RNase and HT-B double KOs were self-compatible. Self-compatibility was measured quantitatively using fruit set, fruit weight, and seed count. Fruit set varied across both self-incompatible and self-compatible lines, with no clear trend in statistical significance. Double KO lines consistently displayed higher fruit weight than incompatible lines. Seed count served as the best measure of self-compatibility, with S-RNase and HT-B double KO lines producing up to three times mean seed per fruit when compared to S-RNase only KOs from prior studies. The lines with the highest levels of self-compatibility will serve as useful additions in advancing potato breeding to the diploid level.

Show moreThe field of applied behavior analysis (ABA) comes with rigorous work expectations and demands. ABA practitioners who are also graduate students must balance the extensive workload of educational and work expectations. Given these demands, graduate students providing ABA services to clients with autism spectrum disorder (ASD) need strategies to maintain their own positive mental health in order to maintain high academic achievement and to prevent burnout. Using a multiple baseline design this study examined whether teaching 6 graduate students enrolled in an ABA master's program who were also working as part-time practitioners providing ABA services to individuals with ASD to use Acceptance and Commitment Therapy (ACT)-based strategies impacted their engagement and active participation during an online synchronous class. Changes in psychological flexibility, stress, and values-behavior were also examined. Although there was no functional relation between the training on using ACT-based strategies and the dependent variables, the lack of effects is likely because the participants enrolled in the study did not have baseline levels that indicated a need for intervention. Additionally, it is hypothesized that competing factors and stressors related to the COVID-19 pandemic likely outweighed the impact of the training to use the ACT-based strategies. The results are discussed more in as well as implications for future research. Keywords: graduate students, behavior technician, Acceptance and Commitment Therapy, psychological flexibility, stress, value driven behavior.

Two legume residues, Vicia villosa - hairy vetch (V) and Pisum sativum - field pea (P) with C:N ratio 12.8 and 10.5 respectively and two non-legume residues, Pennisetum glaucum - pearl millet (M) and Lolium multiflorum - rye grass (R) with C:N ratio 37.8 and 14.3 respectively were used in this study. Soils amended with V and R had greater inorganic N compared to M and P residues while in soils with residue mixtures I observed non-additive synergistic (NAS) effect on inorganic N at the initial and final stage of the incubation period. Long-term N addition increased inorganic N but was apparent with short-term N fertilizer. Addition of both short- and long-term N increased [beta]-1,4,-glucosidase (BG), [beta]-D-1,4-cellobiohydrolase (CBH), phenol oxidase (PO), peroxidase (PER) and acid phosphatase (PHOS) with the exception of Leucine-aminopeptidase (LAP) and urease enzyme activities. There was non-additive antagonistic (NAA) effects on cellulase, total oxidase, [beta]-1,4,-N-acetyl glucosaminidase (NAG) and NAS effects on LAP, urease and PHOS enzyme activities. The addition of residues likely stimulated microbial growth, but the NAA effect of residue mixtures on C acquisition enzyme (cellulase and total oxidase) activities suggests development of C limitation.

The software-defined radio chosen for this work is the SDRplay Radio Spectrum Processor 2 Pro (RSP2pro). The RSP2pro was chosen because of its ability to provide absolute received power measurement capabilities at a price much lower than a traditional spectrum analyzer.The absolute power level and frequency performance of the RSP2pro has been characterized by direct comparison with an electromagnetic compatibility analyzer and the results are shown. A method for automating measurements taken with the RSP2pro companion software is described. The RSP2pro is also used to perform precompliance radiated emissions tests with an electromagnetic compatibility antenna and the results are discussed. Throughout this work a sample of three RSP2pro units is compared and variations in measurements across the three units is examined. A common very-high frequency "rabbit ear" television antenna and an ultra-high frequency "bowtie" television antenna are used with the RSP2pro to create a complete radiated emissions precompliance test setup. A procedure for characterizing these antennas and determining their suitability for radiated emissions precompliance testing is also described. The RSP2pro test setup for measuring radiated emissions is compared to a traditional precompliance test setup consisting of an electromagnetic compatibility spectrum analyzer and an electromagnetic compatibility antenna. This comparison includes a discussion of the relative cost, measurement accuracy, and overall convenience of using each test setup.

Show moreThe current study examined the experiences of race and sexuality related mistreatment in 2,335 racially diverse sexual minorities, the impact of those experiences on depression and anxiety symptoms, and the buffering effects of racial identity and social support. Zero inflated Poisson regression models were utilized for data analysis. Despite sexual minorities of color endorsing more frequent racial- and sexuality-based discrimination compared to their White counterparts, findings indicate they had similar levels of anxiety and depression. Positive racial identity and social support varied by race. Importantly, social support was significantly associated with a decrease in depression and anxiety symptoms for Black sexual minorities with any symptoms. These findings suggest that at low levels of discrimination, sexual minorities of color appear to have resilience against some of the negative psychological consequences of experiencing both race- and sexuality-based discrimination, when compared to White sexual minorities. The resilience against racial discrimination, taught through racial socialization from an early age for many people of color, may generalize to resilience against sexuality-based discrimination. Given the variation of results across racial minorities, this study underscores the importance of an approach to race that preserves each racial groups' unique experiences of discrimination and mental health. Implications of a multidimensional approach to sexuality, challenges in addressing intersectional experiences, and considerations for clinicians working with these vulnerable populations are discussed.

Show moreBackground: In the United States, Black cisgender and transgender women are disproportionately affected by HIV. HIV testing is one of the primary modes of HIV prevention, but a large majority of the HIV testing literature focuses on individual level risk behaviors. Furthermore, there is little known about HIV testing among Black transgender women. This study aims to contribute to the existing literature by (1) examining the HIV testing behaviors of Black transgender women (2) using socioecological theory to assess what sociodemographic factors are associated with HIV testing among Black cisgender and transgender women. Methods: This study uses secondary data from the 2014-2017 modules of the Behavioral Risk Factor Surveillance System. Analyses included multiple hierarchical regression. Results: There are no major differences in HIV testing between Black cisgender and transgender women. A number of sociodemographic characteristics have been shown to predict HIV testing among Black cisgender women, but only employment status and age were significant predictors of HIV testing among Black transgender women. A moderation analyses suggested that gender identity significantly moderates the association between employment status and HIV testing such that the relationship between employment status and receiving an HIV test differs by gender identity. Discussion: The findings of this study highlight nuances that are useful for improving HIV testing as a mode of HIV prevention. Overall, the findings contribute to our understanding of HIV testing practices among Black cisgender and transgender women.

Title: THE EFFECT OF CLAW REMOVAL METHODS AND TEMPERATURE ON THE POST-RELEASE SURVIVAL AND CRITICAL THERMAL MAXIMUM OF STONE CRAB (MENIPPE MERCENARIA)
Creator: Walus, Alexandria Marie
Date: 2022
Collection: Electronic Theses & Dissertations
Description: Florida stone crab (Menippe mercenaria) is an emerging commercial fishery in the Bahamas with its main export to the United States of America. This fishery capitalizes on the oversized claws of the crab, which are harvested, before the crab is returned to the sea where it can potentially regrow its claws. While it is often assumed that the crab will regrow its claws and re-enter the fishery, only 13% of harvested crabs in the fishery have regrown claws, and an estimated 2-81% of crabs survive...
Show moreFlorida stone crab (Menippe mercenaria) is an emerging commercial fishery in the Bahamas with its main export to the United States of America. This fishery capitalizes on the oversized claws of the crab, which are harvested, before the crab is returned to the sea where it can potentially regrow its claws. While it is often assumed that the crab will regrow its claws and re-enter the fishery, only 13% of harvested crabs in the fishery have regrown claws, and an estimated 2-81% of crabs survive post-claw removal and release. In addition, the Caribbean region is considered one of the most vulnerable areas with respect to climate change. Therefore, because most aquatic organisms cannot regulate their body temperature, they are directly influenced by environmental temperature stress, and when combined with the stress of claw removal may further decrease the capacity of the crab to survive warming temperatures. The purpose of my thesis was to: 1) determine a method of claw removal that maximizes survival for stone crab, 2) determine the effect of rapidly warming water temperatures on the reflex behavior of crabs post-release, and 3) determine the effect of claw removal on the critical thermal maximum (CTMax) of stone crab. In chapter 1, I used a controlled laboratory experiment to compare a new autotomy-inducing technique to the typical method of claw removal. For the two different claw removal methods, I compared the survival and start time for claw regeneration as a function of harvester experience and whether one claw or both claws were removed. Finally, the claws that were removed were inspected by independent observers to determine whether any differences using the two methods could be identified. Overall, I found that crabs with claws removed using the proposed induced autotomy method had significantly higher survival than crabs with claws removed using the typical method, while crabs with claws removed by inexperienced harvesters had the lowest. In Chapter 2, I conducted a series of laboratory experiments to measure nine reflex action mortality predictor reflexes of crabs and determine the critical thermal maximum (CTMax) for stone crab that had one or two claws removed using induced-autotomy. Of the nine reflexes used to develop an endpoint necessary for calculating CTMax, three were determined to be suitable (equilibrium, mouth closure and appendage turgor) and CTMax was 37.6 °C, and independent of the number of claws removed using the proposed induced-autotomy method. Overall, the tool required to conduct the induced-autotomy method of claw removal is simple and easily purchased or constructed and can easily be taught to recreational and commercial harvesters as a way to improve survival and thus sustainability of this important fishery.
