Light Spectra Distributions in Temperate Conifer-Forest Canopy Gaps, Oregon and in Tropical Cloud-Forest Canopy, Venezuela

Light Spectra Distributions in Temperate Conifer-Forest Canopy Gaps, Oregon and in Tropical Cloud-Forest Canopy, Venezuela

Date: December 1997
Creator: Monteleone, Susan Elaine
Description: Light spectra distributions were measured in two different montane forests: temperate and tropical. Spectral light measurements were made in different sized canopy gaps in the conifer forest at H. J. Andrews Experimental Forest in Oregon, USA. Researchers at Oregon State University created these gaps of 20 m, 30 m, and 50 m in diameter. In the tropical cloud forest, spectral light measurements were made in two plots that were permanently established at La Mucuy Parque Nacional in Venezuela, in collaboration with researchers at Universidad de Los Andes. In both studies, spectra and distributions of physiologically active light were analyzed: red, far-red, R/FR ratio, and blue light.

An Exploratory Investigation of the Origins and Regulatory Actions of the United Kingdom's Financial Reporting Review Panel

An Exploratory Investigation of the Origins and Regulatory Actions of the United Kingdom's Financial Reporting Review Panel

Date: December 1998
Creator: Styles, Alan K. (Alan Keith)
Description: In 1990, the accounting profession and the British government worked together to establish a new regulatory framework for financial reporting in the United Kingdom (UK), the Financial Reporting Council (FRC) and its two subsidiaries, the Accounting Standards Board (ASB) and the Financial Reporting Review Panel (FRRP). The FRRP enforces companies' compliance with the ASB's accounting standards and the accounting provisions of the UK Companies Act. Only one study, Brandt et al. (1997), has examined the activities and effectiveness of the FRRP. This dissertation attempts to extend Brandt et. al (1997) and add to understanding of the origins and regulatory actions of the FRRP.

The Role of a Point Loss Contingency on the Emergence of Derived Relations in the Absence of Original Relations

The Role of a Point Loss Contingency on the Emergence of Derived Relations in the Absence of Original Relations

Date: December 1997
Creator: Michniewicz, Leslie (Leslie A.)
Description: The role of point loss for symmetrical relations introduced simultaneously with probe trials in the absence of original relations on all probe trial performances was evaluated. Training was completed after six conditional discriminations were established in two contexts. Point loss was introduced simultaneously with probe trials in the absence of original relations in the first context. Probe trials with no point loss in the absence of original relations were introduced in the second context. The simultaneous introduction of probe trials and the point loss contingency may in some cases prevent the emergence of an equivalence class in the context that contained the point loss as well as in the context where no point loss occurred.

Cognitive Dysfunction in Systemic Lupus Erythematosus

Cognitive Dysfunction in Systemic Lupus Erythematosus

Date: August 1997
Creator: Niemela-Waller, Kirsi (Kirsi M.)
Description: The purpose of the study was to determine the point prevalence of cognitive dysfunction in patients with systemic lupus erythematosus (SLE) and to investigate its association with corticosteroids and depression. The severity of dysfunction and the pattern of cognitive changes were examined. This study hypothesized that cognitive dysfunction is common in SLE and many previous studies have underestimated its prevalence, partially due to using limited neuropsychological batteries and insensitive test instruments. It was further hypothesized that the pattern of cognitive changes in SLE patients will resemble that observed in subcortical dementias.

Natural Smooth Measures on the Leaves of the Unstable Manifold of Open Billiard Dynamical Systems

Natural Smooth Measures on the Leaves of the Unstable Manifold of Open Billiard Dynamical Systems

Date: December 1998
Creator: Richardson, Peter A. (Peter Adolph), 1955-
Description: In this paper, we prove, for a certain class of open billiard dynamical systems, the existence of a family of smooth probability measures on the leaves of the dynamical system's unstable manifold. These measures describe the conditional asymptotic behavior of forward trajectories of the system. Furthermore, properties of these families are proven which are germane to the PYC programme for these systems. Strong sufficient conditions for the uniqueness of such families are given which depend upon geometric properties of the system's phase space. In particular, these results hold for a fairly nonrestrictive class of triangular configurations of scatterers.

The Rhetoric of Posthumanism in Four Twentieth-Century International Novels

The Rhetoric of Posthumanism in Four Twentieth-Century International Novels

Date: August 1998
Creator: Lin, Lidan
Description: The dissertation traces the trope of the incomplete character in four twentieth-century cosmopolitan novels that reflect European colonialism in a global context. I argue that, by creating characters sharply aware of the insufficiency of the Self and thus constantly seeking the constitutive participation of the Other, the four authors E. M. Forster, Samuel Beckett, J. M. Coetzee, and Congwen Shen all dramatize the incomplete character as an agent of postcolonial resistance to Western humanism that, tending to enforce the divide between the Self and the Other, provided the epistemological basis for the emergence of European colonialism. For example, Fielding's good-willed aspiration to forge cross-cultural friendship in A Passage to India; Murphy's dogged search for recognition of his Irish identity in Murphy; Susan's unfailing compassion to restore Friday's lost speech in Foe; and Changshun Teng, the Chinese orange-grower's warm-hearted generosity toward his customers in Long River--all these textual occasions dramatize the incomplete character's anxiety over the Other's rejection that will impair the fullness of his or her being, rendering it solitary and empty. I relate this anxiety to the theory of "posthumanism" advanced by such thinkers as Marx, Bakhtin, Sartre, and Lacan; in their texts the humanist view of the individual ...

Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis

Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis

Date: May 1998
Creator: McElhenie, Michael K. (Michael Keith)
Description: Recently, multi-source feedback has been a popular way of providing performance-related feedback to individuals in many organizations. Many who use multi-source feedback consider Rating Convergence, others seeing target individuals as they see themselves, to be a positive outcome of this process. However, the variables that account for Rating Convergence are not known. This study investigated whether the personality factor Extroversion and Behavioral Consistency, acting as a moderator variable, could account for Self-other Rating Convergence, particularly the Convergence between self and peer Ratings. The sample consisted of 235 mid-level managers from a variety of industries who were participants in individual career development workshops. Using structural equation modeling, the results indicated that a model consisting of a single Extroversion factor could account for the convergence of self-peer ratings. This finding calls into question the significance of Rating Convergence when using multi-source rating instruments that provide feedback on trait characteristics since it may be heavily influenced by a single personality factor rather than observers' comprehensive understanding of the ratee's performance.

Date: August 1997
Creator: Ju, Jeongeun
Description: This research study assessed Korean students' perceptions and overall satisfaction levels regarding the effectiveness of their hospitality internship experiences. Relationships with demographic characteristics were identified. The sample was comprised of 74 senior-level university students enrolled in hospitality and/or tourism management programs who were completing an internship in Korea. Generally, students exhibited low agreement levels on the internship program aspects being investigated. Previous work experience was the most common factor influencing students' perceptions of their internship experiences. Agreement levels increased with length of prior work experience. Type of internship workplace, expectation of an employment offer, age and gender were found to influence students' perceptions of the internship experiences.

Mobile Order Theory as Applied to Polycyclic Aromatic Heterocycles

Mobile Order Theory as Applied to Polycyclic Aromatic Heterocycles

Date: August 1997
Creator: Fletcher, Kristin A.
Description: Experimental mole fraction solubilities of benzil, thianthrene, trans-stilbene, thioxanthen-9-one, diphenyl sulfone and dibenzothiophene sulfone are determined in pure noncomplexing and complexing solvents. Predicted solubility values are calculated for benzil, thianthrene, trans-stilbene and thioxanthen-9-one using expressions derived from Mobile Order theory. Large deviations between experimental and predicted solubilities in alcohol solvents exist, therefore optimized solute - solvent association constants are determined. Previously measured thianthrene solubilities in five binary alkane + cyclohexane solvent mixtures are compared with values predicted from Mobile Order theory using the measured solubility in each of the pure solvents as input parameters. The experimental mole fraction solubility of benzil in eight binary alcohol + 1-octanol solvent mixtures are also measured and compared with predicted values.

Distribution and Probable Sources of Nitrate in the Seymour Aquifer, North Central Texas, USA

Distribution and Probable Sources of Nitrate in the Seymour Aquifer, North Central Texas, USA

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Hillin, Clifford K.
Description: This study utilized GIS and statistical methods to map the spatial variability of nitrate and related groundwater constituents in 30 counties above the Seymour Aquifer, analyze temporal patterns of nitrate pollution, identify probable sources of pollution, and recommend water development strategies to minimize exposure to nitrate and reduce future aquifer contamination. Nitrate concentrations in excess of 44 mg/L (US EPA limit) were commonly observed in the Seymour Aquifer region, especially in the central agricultural belt. Data indicated that this is an ongoing problem in the Seymour Aquifer and that agricultural activity and rural septic systems are the likely sources of the nitrate. Inconclusive results emphasized the need for a more comprehensive spatial and temporal water quality monitoring.

"Stately Temples": Consubstantiality and Consciousness in Frances E. W. Harper's Iola Leroy; or Shadows Uplifted

"Stately Temples": Consubstantiality and Consciousness in Frances E. W. Harper's Iola Leroy; or Shadows Uplifted

Date: August 1996
Creator: Louis-Ray, Deborah
Description: The purpose of this master's thesis is to examine Frances Harper's narrative strategy and moral didacticism in Iola Leroy: or Shadows Uplifted (1892) as she strives to achieve consubstantiality and a "heightened consciousness" within her characters and her audience while adhering to the literary and feminist paradigms of the late nineteenth century. Harper identifies with her African-American male audience's dilemma of "double-consciousness" and their veil of androcentrism. She also identifies with her Euro-American female audience's delicate and matriarchal roles, while also attempting to uplift their position of the "Other" to the "One." Finally, with her African-American female audience, Harper identifies with their complex situatedness of "double-consciousness" and the "Other," while also attempting to uplift them from a historically imposed position of selflessness to one of empowerment.

Relationships among and Between Alcohol Consuption Rates, Alcohol Expectancies, and Early Recollections among Three Groups of College Males

Relationships among and Between Alcohol Consuption Rates, Alcohol Expectancies, and Early Recollections among Three Groups of College Males

Date: December 1998
Creator: Taylor, Angela D. (Angela Denise)
Description: Extensive documentation exists which firmly establishes the high use rates and disastrous consequences of alcohol consumption by university students. Use rates for this population have been linked to attitudes toward alcohol consumption, especially alcohol expectancies. Research to date on alcohol expectancies has shown differences in expectancies among various groups. However much of this research has been conducted without a theoretical basis, accomplishing little in explaining how beliefs and drinking behavior are related. The investigation was designed to explore the relationships among and between early recollections and alcohol expectancies and to explore how the contents of early recollections function in relation to expectancies in terms of alcohol consumption patterns among three groups of college males (student-athletes, fraternity men, and independents). The content of individuals' early recollections was analyzed and compared to expectancies and consumption rates for each of the three groups. The study addressed seven hypotheses regarding alcohol consumption rate comparisons, comparisons of consequences experienced as a result of alcohol consumption, comparisons of alcohol expectancies, and comparisons of reported content of early recollections. Multiple regression analysis was utilized to test the extent to which select early recollections and alcohol expectancy scores contributed to the explained variance in alcohol consumption patterns.
