An Analysis Of Registered Sex Offender Reentry Challenges In Mississippi, Kitsya Cordova

Master's Theses

Sex offenders are often considered the most dangerous type of criminal by the public, which is a common misconception (Levenson & D’Amora, 2007; Tewksbury & Copes, 2012). Registered sex offenders usually have the lowest recidivism rates when compared to other offenders (Robbers, 2009). The issue is that registered sex offenders are targeted by multiple set of laws such as the Wetterling Act, Megan’s Law, Adam Walsh Act, among others, Such sex offender legislation creates multiple reentry challenges that other type of offenders may not face (Grossi, 2017; Tewksbury & Copes, 2012). By using secondary data from Griffin and Evans (2019), …

Queering Fertility: Experiences Of Queer/Lesbian People Undergoing Fertility Treatment In A Heteronormative Society, Caitlin Ortis

Master's Theses

Due to the increase in lesbian, gay, bisexual, transgender, queer, and other (+) (LGBTQ+) people seeking fertility treatments or the “Lesbian Baby Boom” (Amato & Jacob, 2004; Batza, 2016; Dunne, 2000; Simon et al., 1993; Mamo, 2013), in which 30% to 50% of women who identify as lesbians hope to become parents (Amato & Jacob, 2004), it is necessary to examine the relationship between a person’s sexual orientation and her experiences receiving fertility treatments. While fertility treatment from a heterosexual perspective has been studied at length, few studies have examined how LGBTQ+ people are treated in fertility clinic settings. In …

Characterizing The Role Of Tumor Suppressors Merlin And Expanded In The Stem Cell Niche Of Drosophila Testes, Bryan Johnson

Master's Theses

The ability of adult organisms to maintain tissue homeostasis and repair tissue in response to injury is mediated by small groups of partially differentiated cells called adult stem cells that support the tissue they reside in. Adult stem cell maintenance is highly regulated by signals from the surrounding microenvironment referred to as the stem cell niche. A better understanding of this process will have important implications for the fields of both regenerative medicine and cancer biology. Due to the complexity of most niche environments in mammals, we turned to the less complex model organism Drosophila and the well-characterized niche in …

Community Policing As Defined By Officers, Benjamin Hesse

Master's Theses

Researchers have struggled to define community policing in a consistent manner for use in scientific study. This study attempts to rectify the disparity in definitions used for research by creating a cohesive definition for use in future research. This definition is was created by conducting in depth interviews with officers as well as by doing a content analysis of police department websites. This research concluded that officers and departments define community policing slightly differently- officers emphasize respect and rapport with the community while departments focus on the specific programs they can implement. Due to these differences, the definition that was …

Evaluation Of Pheromone Mating Disruption For California Red Scale Control In Commercial California Citrus, Joel Timothy Leonard

Master's Theses

California red scale (CRS), Aonidella aurantii, is an increasingly injurious insect pest for the California citrus industry due to insecticide resistance, changing weather patterns, and shifting trade regulations. The presence of the insect on fruit, damages the rind of the fruit and high populations can cause dieback of branches as well as lower yields. Pheromone mating disruption of CRS has the potential to alleviate population control concerns and reduce insecticide use. The efficacy of the pheromone mating disruption technique for pest management of CRS was determined using the products CheckMate® CRS and Semios CRS Plus. CheckMate® CRS was evaluated …

Archaeobotanical Analyses Of The Winterville Mounds Site (22ws500) And Other Southeastern Ceremonial Complexes, Dana Hauffe

Master's Theses

The prehistoric Southeast region of the United States has had very limited archaeobotanical research focused on botanicals’ medicinal or ritualistic characteristics. An analysis of reported botanical remains recovered from Winterville Mounds (22WS500) and seventy- two other Late Woodland and Mississippian sites, from seven states, was conducted to identify their potential medicinal and ritual use of seventy-five botanicals based on reported ethnobotanical evidence. By classifying botanicals into four classes, modeled after the dissertation of Dr. Michele Williams in 2000, taxon frequency and feature ubiquity is configured and utilized to identify the possible ceremonial and medicinal use plants. At Winterville Mounds Site …

The eastern oyster (C. virginica) is a foundation species that improves water quality, protects shorelines, provides refuge for other organisms, and contributes to commercial fisheries. Successful early recruitment of eastern oyster is vital for resupplying adult populations in the face of habitat loss. Coastal oyster populations are challenged by freshwater input, hypoxia, predation and overfishing. Consequently, substantial efforts have been dedicated toward oyster restoration within the northern Gulf of Mexico. The overall objective of this study was to consider the role and importance of early recruitment to oyster restoration in western Mississippi Sound. During the summer 2018 recruitment period, we …

Navigational Feasibility Of Flyby / Impact Missions To Interstellar Objects, Declan Moore Mages

Master's Theses

In October 2017, the first interstellar object, designated 1I/2017 U1 and more commonly referred to as Oumuamua, was detected passing through our solar system by the Pan-STARRS telescope, followed recently by the detection of 2I/Borisov in August 2019. These detections came much sooner than thought possible, and have redefined our understanding of the population of interstellar objects. With the construction of the next generation of powerful observatories, future detections are estimated to occur as frequently as two per year, and while there is significant scientific understanding to be gained from observing these objects remotely, a spacecraft sent to intercept one …

Comparison Of Privacy Schemes In A Multi-Radio Vanet, Collin James Kenner

Master's Theses

Intelligent vehicles are rapidly improving in functionality as they improve upon and incorporate new technologies. The addition of networking capabilities grants vehicles significant knowledge about the location and decisions of vehicles in the surroundings, and allows them to share perception information. However, adversarial listeners in the system may track vehicles by their communications resulting in a loss of user privacy. Past research has attempted to minimize privacy loss in single-radio environments through pseudonym changing schemes. We improved upon this research by comparing pseudonym schemes in a multi-radio environment.

Our simulation environment was created using the OMNeT++ networking and SUMO traffic …

Evaluating Urban Downtown One-Way To Two-Way Street Conversion Using Microscopic Traffic Simulation, Bernice Liu

Master's Theses

Located in the heart of Silicon Valley, Downtown San Jose is attracting new residents, visitors, and businesses. Clearly, the mobility of these residents, visitors, and businesses cannot be accommodated by streets that focus on the single-occupancy automobile mode. To increase the potential for individuals to use non-single-occupancy modes of travel, the downtown area must have a cohesive plan to integrate multimodal use and public life. Complete streets are an integral component of the multi-modal transport system and more livable communities. Complete streets refer to roads designed to accommodate multiple modes, users, and activities including walking, cycling, transit, automobile, and nearby …

Involuntary Signal-Based Grounding Of Civilian Unmanned Aerial Systems (Uas) In Civilian Airspace, Keith Conley

Master's Theses

This thesis investigates the involuntary signal-based grounding of civilian unmanned aerial systems (UAS) in unauthorized air spaces. The technique proposed here will forcibly land unauthorized UAS in a given area in such a way that the UAS will not be harmed, and the pilot cannot stop the landing. The technique will not involuntarily ground authorized drones which will be determined prior to the landing. Unauthorized airspaces include military bases, university campuses, areas affected by a natural disaster, and stadiums for public events. This thesis proposes an early prototype of a hardware-based signal based involuntary grounding technique to handle the problem …

Terrorism And Organized Crime: An Analytical Study From An International Law Perspective, Leila Mejdoubi

Master's Theses

With the spread of terrorism and its growing risks since the start of the 21^st century, a wide range of reports and studies have emerged. This funding comes from a special relationship between terrorist organizations, organized crime syndicates, and their cooperation with each other, which has enabled terrorist organizations in particular to carry out recruitment efforts and operations alike. It has also fueled an international black market for smuggling and trade in drugs and arms. Under what conditions do violent terrorist groups driven by extreme Islamist ideology collaborate with organized criminal enterprises to generate the requisite resources to pursue …

Comparison Of Modern Controls And Reinforcement Learning For Robust Control Of Autonomously Backing Up Tractor-Trailers To Loading Docks, Journey Mcdowell

Master's Theses

Two controller performances are assessed for generalization in the path following task of autonomously backing up a tractor-trailer. Starting from random locations and orientations, paths are generated to loading docks with arbitrary pose using Dubins Curves. The combination vehicles can be varied in wheelbase, hitch length, weight distributions, and tire cornering stiffness. The closed form calculation of the gains for the Linear Quadratic Regulator (LQR) rely heavily on having an accurate model of the plant. However, real-world applications cannot expect to have an updated model for each new trailer. Finding alternative robust controllers when the trailer model is changed was …

A Rotating Aperture Mask For Small Telescopes, Edward L. Foley

Master's Theses

Observing the dynamic interaction between stars and their close stellar neighbors is key to establishing the stars’ orbits, masses, and other properties. Our ability to visually discriminate nearby stars is limited by the power of our telescopes, posing a challenge to astronomers at small observatories that contribute to binary star surveys. Masks placed at the telescope aperture promise to augment the resolving power of telescopes of all sizes, but many of these masks must be manually and repetitively reoriented about the optical axis to achieve their full benefits. This paper introduces a design concept for a mask rotation mechanism that …

Children's Books As Cultural Products: A Qualitative Study Of Cultural Representation In Hmong And Non-Hmong American Books, Malina Her

Master's Theses

This study examined the type of cultural practices and values depicted within Hmong American children’s books in comparison to non-Hmong American children’s books from the United States. The purpose was to explore if prior Hmong traditional practices and values reflective of American individualism would extend to Hmong children’s books. Thirty best-seller children’s books were coded using two checklists, one focused on Hmong traditional practices and the other on American values. Results showed that Hmong traditional practices underscored by Hmong adolescents in prior research somewhat extended to Hmong children’s books. Moreover, in some respects Hmong children’s books displayed similar numbers of …

The Impact Of The Quality Of A Relationship With Supervisors On Employee Work Attitude And Behaviors, Dylan Scott Gilstein

Master's Theses

It has been shown that leader member exchange (LMX) relationships are related positively to subjective career success and negatively to counterproductive work behaviors (CWBs). However, few studies have examined the possible mediators of these relationships. The present study proposed that need satisfaction and intrinsic motivation would mediate the relationship between LMX and both outcomes. It was hypothesized that high-quality leadership relationships would satisfy employees’ psychological needs and intrinsically motivate them which, in turn, would lead them to perceive themselves as more successful in their careers and to engage in fewer CWBs. Using data from 160 participants from an online survey, …

Extended Producer Responsibility And The Environmental Policy Implementation Process In California: A Case Study Of Paintcare, Justin Ian Weiss

Master's Theses

Due to increasing volumes of certain types of waste and the cost of municipal waste management, California and local jurisdictions are pursuing legislation to engage manufacturers in the collection and disposal of the products they manufacture. These legislative frameworks take many forms, but many employ the “producer pays” principle commonly referred to as “extended producer responsibility” (EPR). These policies, which are more common in the European Union, are often contentious and difficult for U.S. governments to pursue, as targeted and influential industries resist policy implementation. The objective of this thesis was to better understand the reasons for the successful implementation …

An Investigation Of The Effects Of Individual Differences On Technology Acceptance In The Workplace, Robert Neil Payne

Master's Theses

The purpose of the current study was to test for moderating effects that conscientiousness, agreeableness, and openness to experience have on relationships in the technology acceptance model. More specifically, the current study tested for previously overlooked moderation effects that these personality traits have on the relationships between behavioral intention and its predictors (i.e. perceived ease of use, perceived usefulness, and subjective norms). A sample of 96 employees from more than 16 industries participated in the study by completing an online survey. Results of the current study displayed a significant moderation effect by agreeableness on the relationship between perceived ease of …

Mindfulness And Resilience As Predictors Of Burnout, Julie Tu

Master's Theses

The faster pace of work due to technological advances and globalization as well as global competition in the workforce may lead to increased chances of stress and burnout among employees. Understanding more predictors of burnout may help companies create better work environments to increase productivity and minimize consequences of burnout (e.g., higher absenteeism, turnover, substance abuse, anxiety, depression). However, not enough research has been done to study the degree to which personality traits predict burnout. Therefore, the purpose of the present study was to examine the degree to which trait mindfulness and trait resilience predict burnout. The study was a …

Numerical Simulations Of Atmospheric Rivers And The Rain Shadow Over The Santa Clara Valley, Jesse Dalton Behringer

Master's Theses

This study investigated precipitation distribution patterns in association with atmospheric rivers (ARs). The Weather Research and Forecasting (WRF) model was employed to simulate two strong atmospheric river events. The precipitation forecasts were highly sensitive to cloud microphysics parameterization schemes. Thus, radar observed and simulated Z_H and Z_DR were evaluated to provide information about the drop-size distribution (DSD). Four microphysics schemes (WSM-5, WSM-6, Thompson, and WDM-6) with nested simulations (3 km, 1 km, and 1/3 km) were conducted. One of the events mostly contained bright-band (BB) rainfall and lasted less than 24 h, while the other contained both BB and non-bright-band …

Bilingual Development: Language Input At Home In Sequential Spanish-English Children, Vanessa Noemy Bermudez

Master's Theses

The literature on language input provided to sequential Spanish-English bilingual children has largely been focused on children attending Head Start. The role of siblings in children’s language outcomes has only been investigated in simultaneous bilinguals. The current longitudinal study extended research on language input by investigating early developmental changes in language input and the role of siblings in the language outcomes of 112 sequential Spanish-English bilingual children. Relative exposure was assessed via a parent interview when children were 18 and 56 months of age. Standardized measures of receptive vocabulary and expressive language in Spanish and English were administered at 56 …

A Phonetic Distance Approach To Intelligibility Between Mam Regional Dialects, Megan Simon

Master's Theses

Mam, an indigenous Mayan language spoken primarily in Guatemala, has considerable internal diversity among its regional dialects. The purpose of this thesis is to estimate their varying degrees of intelligibility and to present groups of dialects whose speakers can be reasonably expected to understand one another. The analysis consists of two parts, the computation of a phonetic distance network and a series of sociocultural interviews. Phonetic distance was measured by Levenshtein distance between cognates in word lists and analyzed with a Neighbor-Net network. Interviews with Mam speakers focused on subjective judgments of intelligibility, contact, and social attitudes. Four main dialect …

The Effects Of Culture And Gender Roles On The Efficacy Of Social Support As A Coping Mechanism For Stress, Quy Minh Vu

Master's Theses

Though social support has been thought to be an effective coping mechanism for handling distress, this generalization comes with limitations in that social support is highly intertwined with specific characteristics that could alter both help-seeking behavior and its outcomes. The present study examined the effects of cultural differences on the effectiveness of differing social support sources (i.e., parents versus peers) between European American and Asian/Asian American samples, as well as the influence of gender role orientation on social support outcomes. Ninety-Five European American and Asian/Asian American participants were assigned to either a parent or peer social support letter task prior …
