Police Officer Coping: The Effect Of Police Culture, Management, And Family, Megan Heflin-Brand

Theses

This thesis examines the idea that police officers have supportive factors in their lives which influence coping mechanisms used to handle occupational stress. This idea comes from police culture literature which suggests that officers are encouraged to use maladaptive coping strategies like drinking and emotional suppression to deal with stress. Additional research on management support and family support are introduced as alternative supportive factors which can promote the use of adaptive coping like agency offered services and programs. This thesis uses data from “Work and Family Services for Law Enforcement Personnel in the United States” (Robert, O’Quin, & Kennedy, 2000). …

Phylogenomic Analysis Of Evolutionary Relationships In Ranitomeya Poison Frogs (Amphibia: Dendrobatidae) Using Ultraconserved Elements, Morgan Renee Muell

Theses

Knowledge of phylogenetic relationships among organisms is essential for anchoring evolutionary studies. Phylogenomic studies use large amounts of genetic data in analyses, which is particularly important for highly phenotypically variable taxa that are difficult to distinguish from one another without the use of genetic data, due to the abundance of homoplasy in morphological characters typically used in morphological classification. Use of genome-scale molecular data has thus become the gold standard for identifying these phylogenetic relationships, specifically in comparison to past studies based on fewer genes. Greater quantities of genetic data, in addition to finer taxon sampling, may lead to different …

The Effect Of Phytoplankton Properties On The Ingestion Of Marine Snow By Calanus Pacificus, Grace Cawley

Theses

The aggregation of phytoplankton into marine snow provides a mechanism by which smaller particles can coagulate to form larger particles, which can be consumed at various depths or readily transported to the deep ocean and sequestered from the atmosphere on time scales of a thousand years or more. Zooplankton interacting with these large carbon-rich aggregates can obtain nutrition in environments where the phytoplankton size spectrum is small and not directly available, enhancing the possibility of obtaining adequate nutrition in environments dominated by small cells. In addition, interactions between zooplankton and marine snow can result in fragmentation, thus affecting the particle …

Open Set Classification For Deep Learning In Large-Scale And Continual Learning Models, Ryne Roady

Theses

Supervised classification methods often assume the train and test data distributions are the same and that all classes in the test set are present in the training set. However, deployed classifiers require the ability to recognize inputs from outside the training set as unknowns and update representations in near real-time to account for novel concepts unknown during offline training. This problem has been studied under multiple paradigms including out-of-distribution detection and open set recognition; however, for convolutional neural networks, there have been two major approaches: 1) inference methods to separate known inputs from unknown inputs and 2) feature space regularization …

High Conductivity Metal–Carbon Nanotube Hybrid Conductors Via Chemical Vapor Deposition And Electroplating, Anthony P. Leggiero

Theses

Metal-carbon nanotube (CNT) hybrid conductors aim to combine the high conductivity of traditional metals with the low mass and temperature coefficient of resistance (TCR) of carbon nanotubes. The high conductivity of copper makes it a promising candidate to combine with CNTs in a hybrid structure, but there is limited physical and electrical interaction between copper and CNTs. The use of an interfacial layer offers one method of improving the interconnection of a Cu-CNT hybrid conductor. In this dissertation, a joule heating-driven chemical vapor deposition (CVD) technique is developed to deposit nanometal seeds throughout a porous, low-density (0.12 g/cm3, ~9 mg/m) …

Query-Driven Global Graph Attention Model For Visual Parsing: Recognizing Handwritten And Typeset Math Formulas, Mahshad Mahdavi

Theses

We present a new visual parsing method based on standard Convolutional Neural Networks (CNNs) for handwritten and typeset mathematical formulas. The Query-Driven Global Graph Attention (QD-GGA) parser employs multi-task learning, using a single feature representation for locating, classifying, and relating symbols. QD-GGA parses formulas by first constructing a Line-Of-Sight (LOS) graph over the input primitives (e.g handwritten strokes or connected components in images). Second, class distributions for LOS nodes and edges are obtained using query-specific feature filters (i.e., attention) in a single feed-forward pass. This allows end-to-end structure learning using a joint loss over primitive node and edge class distributions. …
