An Investigation of Holland's Theory of Vocational Personalities and Work Environments As Applied to Undergraduate Music Majors

Description: Holland's theory of vocational personalities and work environments incorporates four theoretical constructs (congruence, consistency, differentiation and identity) which attempt to explain sources in variability of achievement and satisfaction among employed adults and college students. This study sought to: (1) investigate the relationship of Holland's constructs to academic achievement and educational satisfaction of undergraduate music majors; (2) investigate differences in all variables acc… more

Investigation of Inhibitory Influences in Neuronal Monolayer Networks Cultured from Mouse Spinal Cord

Description: The effects of the inhibitory neurotransmitters gammaamino butyric acid (GABA) and glycine were characterized on spontaneous activity recorded from mouse spinal cord cultures. The GABA concentration which completely inhibited burst activity was chosen as a quantifiable measure of culture drug response and was used to 1) assess interculture and intraculture variability, 2) determine the influence of culture age and initial activity on GABA responses, and 3) compare the GABA responses between net… more

Investigation of Interfacial Property with Imperfection: A Machine Learning Approach

Description: Interfacial mechanical properties of adhesive joints are very crucial in board applications, including composites, multilayer structures, and biomedical devices. Establishing traction-separation (T-S) relations for interfacial adhesion can evaluate mechanical and structural reliability, robustness, and failure criteria. Due to the short range of interfacial adhesion such as micro to nanoscale, accurate measurements of T-S relations remain challenging. The advent of machine learning (ML) became … more

Investigation of Ionic Liquid Phases for Chromatographic Separation of Fentanyl Analogues

Description: Opioid abuse and in particular fentanyl, a synthetic opioid, has been of concern in the last decade. Fentanyl is an illicit drug of concern to due to its prevalence and potency. Research to date has focused on supporting law enforcement by developing methods suitable for chemical profiling and identifying fentanyl from various matrices. However, methods geared towards analysis of fentanyl isomeric analogues are rare. Analysis of isomers is challenging due to similar mass spectral fragmentation … more

An Investigation of Malingering and Defensiveness Using the Spanish Pai Among Spanish-speaking Hispanic American Outpatients

Description: For response styles, malingering describes the deliberate production of feigned symptoms by persons seeking external gain such as financial compensation, exemption from duty, or leniency from the criminal justice system. In contradistinction, defensiveness occurs when patients attempt to downplay their symptoms of psychological impairment. Both of the aforementioned response styles can markedly affect the accuracy of diagnosis, especially on self-reports, such as multiscale inventories. As a… more

An Investigation of Methods for the Concentration of Chemical Compounds Produced by Actinomycetes and Their Relation to Tastes and Odors in Municipal Water Supplies

Description: It is the purpose of this investigation to improve upon techniques to enhance the taste of municipal water and attempt to devise one that could desorb the compounds from carbon in an unaltered state. It was decided that the odor character would be the criterion used to decide if the eluted compounds were the same as those in the raw water.

An Investigation of Naturally Occurring Tastes and Odors from Fresh Waters

Description: The Problem of the cause and control of tastes and odors in water supplies has been the subject of a great many investigations during the last half-century; however, many questions in this field remain to be answered. Theories relating to the cause of tastes and odors occurring in water are still rather numerous and, at present, only a few of them are compatible. Although several procedures have been employed for the eradication of tastes and odors from water supplies, none of them are complete… more
