Unlocking Doors For The Locked-Out: How Can Community Colleges Help To Demolish Barriers, Build Bridges, And Transition Male Ex-Offenders Into The Workforce, Jeannette Collins-Molden

Dissertations

Over 670,000 adult prisoners were released in 2004. It is estimated that by 2010 over 1.2 million inmates will be released annually. The purpose of this study was to explore (a) barriers that male ex-offenders encounter in their pursuit of entering the workforce and (b) various types of education and support services that community colleges could provide in order to assist this marginalized population in overcoming these barriers. This qualitative case study was conducted at a community college offering programs that attracted a population of at least 50% male ex-offenders. Six male ex-offender students, four of the case study institution …

A Psychometric Evaluation Of The Revised Optimism-Pessimism Scale Of The Mmpi-2, Ginger Burge Debrule

Dissertations

The present study tested the psychometric properties of the Revised Optimism-Pessimism Scale (PSM-R) of the MMPI-2. This scale purportedly measures the respondent's explanatory style on a dimension of optimism and pessimism. Participants included 92 college undergraduates and 2,729 participants from archived outpatient data. The PSM-R is a reliable measure, based on test-retest reliability and internal consistency. However, the construct validity of the measure is questionable. Evaluation of the PSM-R items suggests that the items are not all related to the optimism-pessimism construct. In addition, convergent validity of the PSM-R was assessed using measures of attributional style, dispositional optimism, hope, depression, …

The main goal of this dissertation was to examine the processes that shape female mate choice and male reproductive success in an exploded lek species: the White-crowned Manakin (Pipra pipra). The first chapter examined if females select males with certain genetic characteristics to gain indirect fitness benefits. Specifically, it tested whether females preferentially mate with unrelated males or males with high overall heterozygosity to increase the genetic diversity of their offspring. The second chapter examined if food resources within territories affect male mating success of territory …

Evolution And Maintenance Of Plumage Polymorphism: The Case Of The Red-Footed Booby (Sula Sula), Patricia Carvalho Baiao

Dissertations

The red-footed booby (Sula sula) is considered one of the most polymorphic seabirds, with three recognized major adult plumage types: (1) white; (2) white-tailed brown; and (3) brown, and several degrees of intermediates. The ratio of these color morphs varies among populations, with the white morph typically predominating. However, there are a few populations that present an inversed ratio of color morphs, such as Isla Europa in the Indian Ocean and the Galapagos archipelago, with the white-tailed brown or brown morphs predominating. I studied natural populations of red-footed boobies from three geographic locations, namely, the Galapagos archipelago, Johnston Atoll in …

Little To No Stars, Shannon Tate Jonas

Dissertations

This collection of poetry, Little to No Stars, holds poems that often represent the landscape, language, mannerisms, and way of life of the peoples of the Appalachian region of Virginia. In many ways, I view Little to No Stars as a re-visitation to various parts of my childhood, that still linger, where the experiential emotional tension is often balanced, if not countered, by the presence of recurrent landscapes captured and explored in images. I think my work strives for that flow into and within and without the world of the poem. Childhood and the past are alternatively immediate and distant, …

Test Procedures For Equality Of Two Variances In Delta Distributions, Jezaniah Kira Sarion Tena

Dissertations

Statistical literature on testing equality of variances is very broad, encompassing a great number of distributional variations. However, the case of a zero-inflated nonnegative continuous random variable has not yet been considered. Such distribution is specified by a positive probability that the variable assumes a true zero value, together with a conditional distribution for the positive values of the variable.

This study considers the special case, delta distribution, where the positive values come from the lognormal distribution. Test procedures were developed using a statistic based on Gini's Mean Difference. Since the asymptotic distribution of the test statistic was shown to …

The Effects Of Multiple Exemplar Instruction On Generating Functional Interdependence Between Listener And Intraverbal Categorization Repertoires, Sarah A. Lechago

Dissertations

The results of the present study extend the literature on multiple exemplar instruction (MEI) by demonstrating that MEI was ineffective in producing functional interdependence between listener and intraverbal categorization repertoires. Four typically developing children between the ages of 3 years 11 months and 4 years 7 months participated in the study in which two categorization types (listener and intraverbal) were targeted. Previous research has demonstrated functional independence between these two categorization response forms (Petursdottir, Carr, Lechago, & Almason, 2008). The present study examined the efficacy of MEI in the form of alternating categorization response forms (listener and intraverbal) during training …

Statistical Procedures For Bioequivalence Analysis, Srinand Ponnathapura Nandakumar

Dissertations

Applicants submitting a new drug application (NDA) or new animal drug application (NADA) under the Federal Food, Drug, and Cosmetic Act (FDC Act) are required to document bioavailability (BA). A sponsor of an abbreviated new drug application (ANDA) or abbreviated new animal drug application (ANADA) must document first pharmaceutical equivalence and then bioequivalence (BE) to be deemed therapeutically equivalent to a reference listed drug (RLD). The Average (ABE), Population (PBE) and Individual (IBE) bioequivalence have been used to establish the equivalence in the pharmaco-kinetics of drugs.

The current procedure of PBE uses Cornish Fisher's (CF) expansion on small samples. Since …

An attempt is made to explain why the chosen hierarchical form of the …

Clustered Wireless Sensor Networks, Renita Margaret Machado

Dissertations

The study of topology in randomly deployed wireless sensor networks (WSNs) is important in addressing the fundamental issue of stochastic coverage resulting from randomness in the deployment procedure and power management algorithms. This dissertation defines and studies clustered WSNs, WSNs whose topology due to the deployment procedure and the application requirements results in the phenomenon of clustering or clumping of nodes. The first part of this dissertation analyzes a range of topologies of clustered WSNs and their impact on the primary sensing objectives of coverage and connectivity. By exploiting the inherent advantages of clustered topologies of nodes, this dissertation presents …

Closing The Seed Dispersal Loop For Guettarda Viburnoides (Rub.): Connecting Patterns Of Avian Seed Dispersal With Population Growth In A Neotropical Savanna, Andrea Patricia Loayza

Dissertations

This study connects data on frugivore activity, post-dispersal seed fate and plant population demography using stage-specific demographic modeling to examine the role of individual dispersers for plant population dynamics of the fleshy-fruited Neotropical tree Guettarda viburnoides (Rubiaceae) in northeastern Bolivian savannas. Detailed information on frugivory and seed dispersal of G. viburnoides reveals that the endocarps of this plant are dispersed mainly by two species of birds: Cyanocorax cyanomelas and Pteroglossus castanotis, which are defined as the quantitatively important dispersers of G. viburnoides. These two species differ in several qualitative aspects of seed dispersal: 1) They select fruits of …

The Impact Of Fast Forword On Mct Scores And Student Achievement, Michael Harvey Van Winkle

Dissertations

Educators today were concerned with how the No Child Left Behind Act of 2001 dealt with the improvement of education throughout the United States. Schools should have put forth a greater effort and reduced the achievement gap between different groups of students based on race, gender, special education status, and if that student was economically disadvantaged. A problem was identified as low student MCT scores in the state of Mississippi. A tutorial method that claimed to help improve students in the areas of reading and language was identified as Fast ForWord.

This study set out to find if there was …

Investigation Into Select Isoquinolines As A Putative Causal Agent Of Ethanol Addiction In Mammals, Jacob Christopher Strawbridge

Dissertations

Alcohol is the most abused drug in America today. The neurological root of the problem is still a much debated subject and many differing views exist on the nature of alcoholism, be it a social dysfunction or a neurochemical imbalance. Some researchers have proposed that a skewed metabolism of dopamine that results in the formation of tetrahydroisoquinoline (THIQ) alkaloids plays a major role in the neurochemical acquisition and maintenance of alcohol addiction. In an effort to better understand the relationship of THIQ's to alcohol addiction, a series of experiments have been conducted. The chiral separation via high pressure liquid chromatography …

Development And Psychometric Evaluation Of The Provider Response To Emergency Pandemic (Prep) Tool, Linda Suzzanne Good Phd

Dissertations

Background: History and science would suggest that a worldwide influenza pandemic is near and its implications are on the minds of healthcare workers (HCWs). Previous studies revealed that HCW have loss-related fears and concerns associated with working during a disaster, especially one with a biologic component. Most healthcare organizations have well-crafted disaster plans in place; however, these plans often rely on the assumption that HCWs will report to work as usual, which may not be the case. Objective: The purpose of this study was to determine if HCWs' fears and concerns are a predictor of their willingness to report to …
