Sociocultural Considerations and the Parallel Agendas of Music and Text in the Lullaby

Description: This research is an investigation of how the lullaby, which is often viewed as purely a simple and pretty song, is a multifaceted vocal tradition that carries historical and cultural significance. As an exploration of how sociocultural factors impact the emotions expressed and the stories told in lullabies, this research encourages deeper examinations of lullaby texts in relation to the historical, cultural, and social aspects reflected in their textual themes. Through the close analysis of tex… more

Role of 5.8S rRNA in Zebrafish and Human Blood Coagulation

Description: Hemolytic disorders are characterized by hemolysis and are prone to thrombosis. Previously, it has been shown that the RNA released from damaged blood cells activates clotting. However, the nature of RNA released from hemolysis is still elusive. We found that after hemolysis, the red blood cells from both zebrafish and humans release 5.8S rRNA. This RNA activated coagulation in zebrafish and human plasmas. Using both natural and synthetic 5.8S rRNA and its synthetic truncated fragments, we foun… more

Re-Assessing Nationalism in the Art Songs of Jaime León

Description: Colombian composer Jaime León (1921-2015) is known for his art songs. Most of the current scholarly literature about León defines him as a nationalist composer even though a majority of his songs do not appear to have nationalist traits. This document examines a representative selection of León's songs divided into three categories: songs influenced by the bambuco (the Colombian genre most present in his songs); songs whose text refers to Colombian culture; and songs without Colombian elements … more

Development and Disruption of Collateral Behavior and DRL Performances: A PORTL Exploration

Description: One schedule of reinforcement that is used to decrease the rate of a target behavior is differential reinforcement of low rates (DRL). During this schedule, reinforcement is delivered for a target response if it occurs after a certain amount of time has passed since the last instance of this target response. The current study used a table-top game called PORTL and college student participants to investigate how collateral patterns develop and are disrupted during DRL schedules. After the partic… more

Epidemiologic Survey of a Unique Type of Task-Specific Dystonia in Brass Musicians

Description: Brass musicians are known to experience a performance problem that is sometimes called valsalva maneuver or musical stuttering. This problem is known to cause difficulty starting a first note, tension in the throat, and tightness in the chest. Unfortunately, the research literature lacks sufficient details for evidence-based interventions. Therefore, the purpose of this study is to characterize and define this performance problem as experienced by brass musicians. An online epidemiologic survey… more

User Privacy Perception and Concerns Regarding the Use of Cloud-Based Assistants

Description: Cloud-based assistants like the Google Home and the Amazon Alexa have become ubiquitous in our homes. Users can simply communicate with the devices using a smartphone application. There are privacy concerns associated with cloud-based assistants. For example, users do not know what type of information is being sent to the device manufacturer, if the device is stealthily listening to conversations, data retention, or who else has access to the data. Privacy is about perception. The goal of this … more

Class Enumeration and Parameter Bias in Growth Mixture Models with Misspecified Time-Varying Covariates: A Monte Carlo Simulation Study

Description: Growth mixture modeling (GMM) is a useful tool for examining both between- and within-persons change over time and uncovering unobserved heterogeneity in growth trajectories. Importantly, the correct extraction of latent classes and parameter recovery can be dependent upon the type of covariates used. Time-varying covariates (TVCs) can influence class membership but are scarcely included in GMMs as predictors. Other times, TVCs are incorrectly modeled as time-invariant covariates (TICs). Additi… more

The Consequences of Early Life Stage Thyroid Suppression on Immune Function in the Fathead Minnow (Pimephales promelas)

Description: Current evidence suggests that thyroid hormones (THs) may impact development of the immune system. However, studies that explore the role of THs in immune development are limited, and the mechanisms leading to alterations in immune function are poorly understood. It is important to elucidate the role of THs in immune development given that many environmental contaminants have been shown to disrupt TH homeostasis and may also have negative impacts on the immune system. As such, the main goal of … more

A Top-Down Policy Engineering Framework for Attribute-Based Access Control

Description: The purpose of this study is to propose a top-down policy engineering framework for attribute-based access control (ABAC) that aims to automatically extract ACPs from requirement specifications documents, and then, using the extracted policies, build or update an ABAC model. We specify a procedure that consists of three main components: 1) ACP sentence identification, 2) policy element extraction, and 3) ABAC model creation and update. ACP sentence identification processes unrestricted natural … more

Perception of Falls and Confidence in Self-Management of Falls among Older Adults

Description: Mobility safety, especially fall prevention, plays a significant role in successful aging for older adults. Fall preventive programs aim to reduce risks for mortality from fall-related injuries among older adults. However, the covariation between personal perceptions of falls and factors and confidence of self-management in falls (CSMoF) is still under-studied despite its importance to fall prevention. Using the International Classification of Functioning, Disability, and Health (ICF) model, th… more

Interlocal Competition and Local Fiscal Health

Description: A sizeable literature documents patterns of competition between local governments in metropolitan regions, while also exploring variation in such local government financial attributes as efficiency, budget size, fiscal disparity, and service equity, which are frequently bound together under the concept of fiscal health. However, the concept of fiscal health is broader and more sophisticated than any one fiscal measure, and empirical studies tend to focus only on multi-purpose governments. This … more

Fabrication of Nano-Channel Templates and a Study of the Electrical and Magnetic Properties of Nanowires Grown in Template Pores

Description: This thesis is a study of the structural, electrical and magnetic properties of indium antimonide (InSb) nanowires (NWs), that were synthesized by a template-assisted ordered growth technique via electrochemical deposition. InSb was chosen for this study because of its intrinsic properties that make it a material of choice for applications in high channel mobility, infrared (IR) sensing, thermoelectrics, and magnetoresistive sensing martials. This work has four main components: (i) Growth in co… more
