The Investigation And Characterization Of The Reaction Of 2-Methylfuran And 2-Methyl-3-Buten-2-Ol With O(3p) And The Photodissociation Of Xylyl Bromide Isomers, Yasmin Fathi

Master's Theses

This thesis has studied the oxidation behavior of different biofuels or additives, 2-methyl-3-buten-2-ol and 2-methylfuran, in combustion experiments at the Chemical Dynamics Beamline held at the Advanced Light Source of the Lawrence Berkley National Laboratory. The oxidation of these fuels were initiated through O(³P) and the combustion experiments were analyzed using a multiplexed chemical kinetics photoionization mass spectrometer with tunable synchrotron radiation. Products of the different reactions were identified using kinetic profiles and further characterized using the photoionization spectra. The amount of each species was calculated using branching fractions.

Additionally, the unimolecular dissociation of the xylyl bromide isomers …

Are We Out Of The Woods Yet? How Democrats And Progressives Need To Rethink Their Message Framework, Lauren E. Feuerborn

Master's Theses

The aftermath of the election revealed that the Democratic Party made critical errors and had structural issues that made executing our messaging more difficult. The Democratic Party needs to return to a set of principles that prioritizes all people and their wellbeing to win elections. What do Democrats and progressives need to fix so they can deliver better messages? To better understand the dynamics that impact the Democratic Party’s capacity to create messaging I believe one must look at the relationship between the Democratic Party as an institution and the art of political messaging. The research of this paper focuses …

Generating Prevalence Estimates Of Sensitive Behaviors Through List Randomization: Survey Experiment Among Indian Males, Abha Indurkar

Master's Theses

Survey respondents may under-report or misreport sensitive behaviors due to social desirability bias. List randomization is an indirect way of asking questions which allows respondents to answer sensitive questions without the surveyor knowing their actual response. This has emerged as a new technique to ask sensitive questions as it reduces respondent’s discomfort while reporting sensitive behaviors. In this study, we apply list randomization to generate prevalence estimates of sensitive behaviors and perception related to homosexuality, molestation of women and notion of partner purity in the sample of young, college educated Indian males. Our findings are consistent with the literature on …

La Madre Competitiva: An Experimental Study Of Women's Competitiveness In Medellin, Colombia, Miranda I. Lambert

Master's Theses

Abstract: This project is a follow up to Cassar, Wordofa, and Zhang (2015), which aimed at testing whether extending incentives beyond cash would alter the estimated competitive tendencies of men and women. Here we extend this work to an urban Colombian setting. In the previous study conducted in China, men have proven more competitive than women; however, once the incentive changes to a child-benefitting voucher, women increased their likeliness to compete. This research uses statistical and regression analysis to test whether or not women become more competitive when competing for a voucher, which directly benefits their child as opposed to …

Competitive Mothers: An Experimental Study Of Female Competitiveness And Polygamy In Togo (West Africa), Aminata Cissokho

Master's Theses

Are women in a patriarchal society like Togo as competitive as men? How does being a parent, in a polygamous vs. monogamous marriage and having high income affect one’s willingness to compete? With an incentivized experiment, we explore whether there are gender differences in selecting into competitive environments, especially when the incentives switch from cash to voucher. This experiment is conducted in Togo, West Africa, with 428 subjects including females-males, parent-non parent. Overall, the findings reveal no significant differences between the females and males’ willingness to compete. Female parents are more competitive than male parents regardless of the incentive. Subjects …

Gender Differences In Willingness To Compete: Experimental Evidence From Bosnia, Boris Jokic

Master's Theses

Abstract: This research examines gender differences in willingness to compete with differing incentives . The results of previous experiments show that women are significantly less competitive, even when they perform equally well as men. However, in these experiments cash was the only incentive provided. Therefore, we investigate what happens to gender differences in willingness to compete when we switch the incentive from cash to non-cash prize. Similar to Cassar, Whordofa, and Zhang (2016) who found that women become equally competitive as men when incentive is related to wellbeing of their children, we find that the gender gap in competitiveness still …

Investigation Of Absolute Photoionization Cross Sections Of Cyclic Ketones, Low Temperature Combustion Of Propargylamine By Synchrotron Photoionization Mass Spectrometry, And Computational Study Of Hypersalts, Chelsea Liliana Price

Master's Theses

The presented research was carried out at the University of San Francisco. Measurements of absolute photoionization cross sections of both cyclopentanone and cyclohexanone, as well as the Cl-initiated oxidation of propargylamine were completed through the use of a multiplexed photoionization mass spectrometer (MPMIS) located at the Lawrence Berkeley National Laboratory Advanced Light Source (ALS). Furthermore, the design of novel LiF containing hypersalts, constructed from superhalogens and superalkalis, were explored due to their enhanced ionization energies and electron affinities. All determined calculations were completed using the CBS-QB3 composite model with the Gaussian09 program.

Goal Effectiveness In Achieving Educational Outcomes: Experimental Evidence From 9th Graders In Medellin, Colombia, Daniel Salicath, Alessandra Cassar

Development And Application Of A 30-Year Vegetation Dataset To Assess The Impacts Of Fence Removal Within The Kruger To Canyons Biosphere Reserve, South Africa, Helaine M. Linden

Master's Theses

Maintaining habitat heterogeneity is favorable when conserving protected areas due to its positive relationship with biodiversity. Fence removal across protected areas improves connectivity and allows herbivory to occur over a larger landscape extent. In the mid-1990’s, reserves within the Kruger to Canyons Biosphere Reserve (K2C) removed their fences, becoming connected to Kruger National Park (KNP). The fundamental research objective was to determine how fence removal influenced the vegetation dynamics within the reserves residing in the K2C. We had three goals: 1) determine if multiple satellite sensors could be used within the TIMESAT program to provide robust vegetation metrics that measure …

Schuell’S Stimulation Approach Administered Intensively For An Individual With Chronic, Severe Non-Fluent Aphasia, Shannon K. Hughes

Master's Theses

Background: Schuell’s Stimulation Approach is frequently implemented within conventional speech language therapy (SLT) for aphasia. Recent research supports the use of intensive treatment, as well as the potential for continued gains in the chronic stage of aphasia. Given the limited evidence-based treatment options for individuals with chronic, severe non-fluent aphasia, investigation was warranted.

Aims: The current study used a single subject design with multiple probes across behaviors to investigate how an individual with chronic, severe non-fluent aphasia, who had ceased to make gains in conventional SLT, would respond to administration of Schuell’s Stimulation Approach at the standard intensive dosage of …

Calibration Of Cr-39 Nuclear Track Detectors With Alpha-Particles And Protons For A Measurement Of Neutron Interactions With 7be And The Primordial 7li Problem, Emily E. Kading

Master's Theses

The Primordial Lithium problem of Big Bang Nucleosynthesis (BBN), a prediction of ⁷Li abundance which is considerably larger than observed, has important implications for the standard model of cosmology. Since ⁷Li is produced by the later decay of ⁷Be it is important to study the destruction of ⁷Be during the epoch of BBN, in order to examine possible reduction of the predicted abundance of ⁷Li, in particular the destruction of ⁷Be with neutrons. The high flux of 50 keV epithermal neutrons (10¹⁰ n/sec/cm²) produced by a Liquid Lithium (LiLiT) target at …

Hip Muscle Activity During A Functional Movement Assessment, Colleen M. Driscoll

Master's Theses

CONTEXT: Neuromuscular control throughout functional movement is a risk factor for lower extremity injury. When implemented correctly, some preventive training programs (PTPs) decrease injury risk while focusing on strengthening the gluteus medius. Specific changes to faulty biomechanics are typically not accomplished. Understanding the causes of these risk factors, and techniques to manipulate them are crucial in injury prevention. OBJECTIVE: To evaluate potential differences in hip musculature activation, gluteus medius (GMed), gluteus maximus (GMax), and adductor magnus (ADD), during a jump-landing task between females with and without medial knee displacement (MKD). Additionally, to determine associations between hip muscle activation, vertical ground …

Centering Error For Range Poles, Kevin D. Franklin

Master's Theses

A land surveyor makes accurate measurements using knowledge, physical dexterity, and properly calibrated equipment. All measurements contain errors, but the professional surveyor is mindful of the various sources and consciously works to minimize them based on experience and informed decision making. One such error source is the level vial, a standard component of numerous survey instruments and accessories. This paper derives expected miscentering error from a circular sprit level with an example using a global navigation satellite system (GNSS) range pole as commonly used for real-time kinematic positioning. We demonstrate that when the length of a 2-m, 40 min:2 mm, …

The Effect Of Blood Flow Restriction Training With The Quadmill On Peak Isometric Knee Extensor Strength 2017, Brandon Schrom

Master's Theses

Traditional training methodologies that improve muscular strength use loads as low as 75% of a person’s one-repetition maximum and as high as 110% of a person’s one repetition maximum. With these high loads comes a greater risk for injury. Blood flow restriction (BFR) training is a potential solution to this problem. BFR training originated in Japan, where it was called Kaatsu. With this method of training, a trainee ties a tourniquet around the proximal end of a limb to reduce blood flow to and from the limb’s muscles. The purpose of this study was to determine whether three-weeks of BFR …

Philosophers On The Fringe: Albert Schweitzer, Liberty Hyde Bailey, Aldo Leopold, And The Wrongful Polarization Of Environmentalist History 2017, Minnie A.M. Lauzon

Master's Theses

This thesis includes three articles (chapters) intending to encourage clarification of an area of environmental history that has not received adequate attention since the publication of Roderick Nash’s Wilderness and the American Mind. Since its publication in 1967, little research has been dedicated to understanding the scholarly or philosophical influence Albert Schweitzer and Liberty Hyde Bailey had on Aldo Leopold. Since my undertaking of this topic, I have established two primary goals. First, I want to provide clarification to environmentalists, academics, and the populace at large that environmentalism does not have to be bound by rules and convention, but can …

The ATS Chiller had leaky pipes that needed to be refurbished and a shroud was implemented to improve thermal capabilities of the system. The full system was able to reach temperatures as low as -38ºC and as high as 58ºC at a pressure of 10-6 Torr. The ATS …

Models For Pedestrian Trajectory Prediction And Navigation In Dynamic Environments, Jeremy N. Kerfs

Master's Theses

Robots are no longer constrained to cages in factories and are increasingly taking on roles alongside humans. Before robots can accomplish their tasks in these dynamic environments, they must be able to navigate while avoiding collisions with pedestrians or other robots. Humans are able to move through crowds by anticipating the movements of other pedestrians and how their actions will influence others; developing a method for predicting pedestrian trajectories is a critical component of a robust robot navigation system. A current state-of-the-art approach for predicting pedestrian trajectories is Social-LSTM, which is a recurrent neural network that incorporates information about neighboring …

Penstemon harringtonii is encountering threats from habitat destruction and fragmentation due to oil and gas exploration, livestock grazing and recreational activities. Penstemon harringtonii is scattered across six counties in north central Colorado. The populations split into three general areas, one around Eagle and north to Kremmling, from Glenwood Spring south to Aspen and around the community of Rifle. The disjunct nature of the species has raised questions related …

Potato Plant Gene Expression And Physiology During Three-Way Interactions With Mycorrhizal Fungi And Lepidopteran Larvae, Andrew P. Schoenherr

Master's Theses

Arbuscular mycorrhizal fungi (AMF) are integral components of ecosystems and form root associations with the majority of land plants (>80%). In these relationships, AMF provide essential nutrients to their hosts, primarily phosphorus, in exchange for photosynthates, which enhance plant growth and help plants overcome environmental stress. The below-ground interaction between plants and AMF can indirectly alter aboveground plant interactions with insect herbivores. Potatoes (Solanum tuberosum) which are considered one of the most important vegetable crops worldwide, naturally form symbioses with AMF. However, it is not well understood how the association between potatoes and AMF can potentially affect leaf-chewing insect …
