Comparative mitochondrial DNA sequence diversity in isolated and open populations of Southern flying squirrels (Glaucomys volans)

Comparative mitochondrial DNA sequence diversity in isolated and open populations of Southern flying squirrels (Glaucomys volans)

Access: Use of this item is restricted to the UNT Community.
Date: August 1999
Creator: Cook, Melaney Birdsong
Description: Three populations of Southern flying squirrels were studied in the Ouachita Mountains of Arkansas to assess the impact of population subdivision-due to island formation--on the population genetics of Glaucomys volans. One island, one mainland, and one open population were investigated. A 367 nucleotide hypervariable region of mitochondrial DNA was sequenced in individuals from each population. Individuals and populations were compared to assess relatedness. Higher sequence diversity was detected in the open and island populations. One island individual shared characters with both the island and mainland populations. Results support the hypothesis that the mainland population may have reduced gene flow. Also, the island population may have been originally founded by at least two maternal lineages.

Comparative Study of the Bel Canto Teaching Styles and their Effects on Vocal Agility

Comparative Study of the Bel Canto Teaching Styles and their Effects on Vocal Agility

Date: August 1996
Creator: Harper, Portia
Description: This thesis examines the historical significance of the vocal methods employed from the middle of the seventeenth century to the beginning of the nineteenth century in what became known as the bel canto era. It provides further exploration into the pedagogical procedures of the bel canto technique through a study of the premier instructors and singers from this period. The resurgence of interest in this tradition is addressed along with its impact on current vocal pedagogy. The vital role that vocal agility played as one of its most distinguishing traits is the primary factor under investigation. A discussion of the bel canto teaching styles in relation to their approach to agility is a major point of inquiry. By maintaining a link between present artists and pedagogues and the old Italian school, it helps the singer understand the historical implications of vocal agility as an integral part of healthy vocal development.

Comparing Quality of Life: American and Portuguese Cancer Patients with Hematological Malignancies

Comparing Quality of Life: American and Portuguese Cancer Patients with Hematological Malignancies

Date: December 1997
Creator: Forjaz, Maria João
Description: The purpose of this study is to investigate the differences and similarities of quality of life (QoL) in American and Portuguese cancer patients with hematological malignancies as well as the robustness of the measures cross-culturally. Portuguese participants were 98 patients and 49 accompanying persons and the American participants were 55 patients and 22 accompanying persons. Fifty (Portuguese sample) to 40% (American sample) of the patients came with an accompanying person who answered the questionnaire concerning the patient's QoL. The two cultural groups were characterized in terms of QoL (measured by the SF-36 and the FLIC), social support (Social Support Scale), socio-demographic and clinical variables. Portuguese patients reported a higher QoL. However, this result could be attributable to the fact that the two cultural samples differ in socio-economic status. The measures seem to be comparable for the Portuguese and American samples, at least in what concerns reliability and concurrent validity.

A Comparison between the Self-concept of Visually-impaired Adults and Sighted Adults

A Comparison between the Self-concept of Visually-impaired Adults and Sighted Adults

Date: May 1995
Creator: Martinez, Ramiro, 1964-
Description: Self-concept scores of 19 visually-impaired adults were compared to those of 19 matched sighted adults using the Tennessee Self-Concept Scale (TSCS). All participants attended the University of North Texas. Scores were examined against the Vocabulary and Information subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R).

A Comparison of Economic Development in Latin America, Middle Eastern Europe and Asia in the 1990s

A Comparison of Economic Development in Latin America, Middle Eastern Europe and Asia in the 1990s

Date: May 1999
Creator: Marktanner, Marcus
Description: The 1990s were characterized by severe turbulence in the global economy. Economic and financial crises occurred in Latin America, Middle and Eastern Europe and Asia. This analysis distinguishes between the two socioeconomic criteria "transitional" and "emerging" region. Transitional countries are former centrally planned socialist economies and emerging countries former agricultural-oriented classical developing economies with mostly a history of military or some other kind of autocratic dictatorship. The resources for the analysis are data sets regarding investment, exchange rate behavior, government finance, international liabilities of monetary authorities and inflation. The study reveals macroeconomic patterns associated with economic development in each socioeconomic region. It is shown that similar patterns are responsible for successful and non-successful performance in each region. A comparison of different regions shows many parallels between emerging economies, but only little similarity between transitional economies.

Comparison of Remediation Methods in Different Hydrogeologic Settings Using Bioplume II

Comparison of Remediation Methods in Different Hydrogeologic Settings Using Bioplume II

Date: May 1996
Creator: White, Sherry A. (Sherry Anne)
Description: A contaminant fate and transport computer model, Bioplume II, which allows simulation of bioremediation in ground water systems, was used to compare the effects of 11 remediation scenarios on a benzene plume. The plume was created in three different hydrogeologic settings from the simulation of an underground gasoline storage tank leak.

The Computation of Ultrapowers by Supercompactness Measures

The Computation of Ultrapowers by Supercompactness Measures

Date: August 1999
Creator: Smith, John C.
Description: The results from this dissertation are a computation of ultrapowers by supercompactness measures and concepts related to such measures. The second chapter gives an overview of the basic ideas required to carry out the computations. Included are preliminary ideas connected to measures, and the supercompactness measures. Order type results are also considered in this chapter. In chapter III we give an alternate characterization of 2 using the notion of iterated ordinal measures. Basic facts related to this characterization are also considered here. The remaining chapters are devoted to finding bounds fwith arguments taking place both inside and outside the ultrapowers. Conditions related to the upper bound are given in chapter VI.
