New England Governors/Eastern Canadian Premiers Climate Change Action Plan 2001

New England Governors/Eastern Canadian Premiers Climate Change Action Plan 2001

Date: August 2001
Creator: The Committee on the Environment and of the Conference of New England Governors and Eastern Canadian Premiers
Description: Recognizing the need for the region to provide leadership on the critical issue of climate change and greenhouse gas (GHG) emissions, the New England Governors and Eastern Canadian Premiers established the regional climate change program in 2000. While the northeast represents a significant economic region with greenhouse gas emissions roughly equivalent to those of Spain, climate change is an international issue for which our states and provinces are only a relatively small part of the problem. However, through their leadership the Governors and Premiers have established our region as an internationally-recognized part of the solution.

A Novel Mechanism for Site-Directed Mutagenesis of Large Catabolic Plasmids Using Natural Transformation

A Novel Mechanism for Site-Directed Mutagenesis of Large Catabolic Plasmids Using Natural Transformation

Date: August 2001
Creator: Williamson, Phillip C.
Description: Natural transformation is the process by which cells take up DNA from the surrounding medium under physiological conditions, altering the genotype in a heritable fashion. This occurs without chemical or physical treatment of the cells. Certain Acinetobacter strains exhibit a strong tendency to incorporate homologous DNA into their chromosomes by natural transformation. Transformation in Acinetobacter exhibits several unique properties that indicate this system's superiority as a model for transformation studies or studies which benefit from the use of transformation as an experimental method of gene manipulation. Pseudomonas putida is the natural host of TOL plasmids, ranging between 50 kbp and 300 kbp in size and encoding genes for the catabolism of toluene, meta-toluate, and xylene. These very large, single-copy plasmids are difficult to isolate, manipulate, or modify in vitro. In this study, the TOL plasmid pDKR1 was introduced into Acinetobacter calcoaceticus strains and genetically engineered utilizing natural transformation as part of the process. Following engineering by transformation, the recombinant DNA molecule was returned to the native genetic background of the original host P. putida strain. Specific parameters for the successful manipulation of large plasmids by natural transformation in Acinetobacter were identified and are outlined. The effects of growth phase, total ...

The Occupational Aspirations and Expectations of Students Majoring In Jazz Studies At The University Of North Texas

The Occupational Aspirations and Expectations of Students Majoring In Jazz Studies At The University Of North Texas

Date: August 2001
Creator: Ramnunan, Karendra Devroop
Description: The purpose of this study was to identify the occupational aspirations and expectations of students majoring in jazz studies, and to investigate relationships between students' aspirations, expectations and selected variables including significant others, choice of school, instrument type, academic achievement, academic level, socioeconomic status, age, gender, and early jazz experience. All jazz studies majors enrolled at the University of North Texas during the Spring 2001 academic semester responded to a pilot test questionnaire (return rate 85%, N = 211). Frequencies, percentages, means, and standard deviations described the students' occupational aspirations, occupational expectations, backgrounds and training in jazz prior to entering UNT, and determined the extent to which parents, relatives, teachers, friends, and role models helped steer them into jazz (Pearson r, Spearman Rho and Point Biserial correlation coefficients provided). The low to moderate positive correlation between aspirations and expectations (r = 0.43) indicated that the two variables were different and measured different types of occupations. Fifty percent of students aspired to be jazz performers whereas 29.7% expected to be jazz performers. While 42% aspired to be engaged in a combination of occupational activities, 48% expected a combination of occupational activities. Only 4.7% aspired to teach; however, almost 16% expected to ...

Palmitoyl-acyl carrier protein thioesterase in cotton (Gossypium hirsutum L.): biochemical and molecular characterization of a major mechanism for the regulation of palmitic acid content.

Palmitoyl-acyl carrier protein thioesterase in cotton (Gossypium hirsutum L.): biochemical and molecular characterization of a major mechanism for the regulation of palmitic acid content.

Date: August 2001
Creator: Huynh, Tu T
Description: The relatively high level of palmitic acid (22 mol%) in cottonseeds may be due in part to the activity of a palmitoyl-acyl carrier protein (ACP) thioesterase (PATE). In embryo extracts, PATE activity was highest at the maximum rate of reserve accumulation (oil and protein). The cotton FatB mRNA transcript abundance also peaked during this developmental stage, paralleling the profiles of PATE enzyme activity and seed oil accumulation. A cotton FatB cDNA clone was isolated by screening a cDNA library with a heterologous Arabidopsis FatB probe (Pirtle et al., 1999, Plant and Cell Physiology 40: 155-163). The predicted amino acid sequence of the cotton PATE preprotein had 63% identity to the Arabidopsis FatB thioesterase sequence, suggesting that the cotton cDNA clone probably encoded a FatB-type thioesterase. When acyl-CoA synthetase-minus E. coli mutants expressed the cotton cDNA, an increase in 16:0 free fatty acid content was measured in the culture medium. In addition, acyl-ACP thioesterase activity assays in E. coli lysates revealed that there was a preference for palmitoyl-ACP over oleoyl-ACP in vitro, indicating that the cotton putative FatB cDNA encoded a functional thioesterase with a preference for saturated acyl-ACPs over unsaturated acyl-ACPs (FatA). Overexpression of the FatB cDNA in transgenic cotton ...

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits

Date: August 2001
Creator: Edwards, Kimberly
Description: Semantic clustering has been used as a measure of learning strategies in a number of clinical populations and has been found to be deficient in individuals with Schizophrenia, but less attention has been paid to the dynamic use of this strategy over the course of fixed-order learning trials. In the current study, we examined this pattern of clustering use over trials in a sample of individuals with Schizophrenia, and explored whether the addition of this dynamic information would help us to better predict specific executive deficits. Results suggested that a decrease in semantic clustering across trials was associated with some executive deficits in the predicted manner. Nonetheless, the overall semantic clustering index generally proved more effective for the purposes, suggesting that in this population, the addition of dynamic information in strategy use is not likely to add considerably to clinical prediction and understanding.

Perceived Submaximal Leg Extension Forces of Young Adult Males

Perceived Submaximal Leg Extension Forces of Young Adult Males

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Ludke, Andrew William
Description: The purpose was to examine actual force (AF) productions of males for accuracy during leg extensions when given a random desired force (DF) ranging from 10-90% of maximal force (MF). Thirty males ranging from 18 to 30 years of age (M = 21.99 + 3.04), who had no previous experience with the test equipment, went through 9 randomly ordered submaximal efforts followed by a maximal effort. Correlations between AF and DF were high (r > .79) and test-retest was consistent between AF (r = .87) and MF (r = .90). Participants consistently undershot DF on both test and retest from 20-90% and overshot DF only at 10%. Power functions revealed exponents of less than 1, indicating that AF grows slower then DF for both test .70 (.95 CI = .63 - .77) and retest .66 (.95 CI = .60 - .73). The results replicate a prior study by Jackson, Martin, Koziris, Ludtke, and Dishman (2001) that used incremental rather than random increases in DF.

Perceptions of assurance service services performed by certified public accountants: Accounting education assessment applications

Perceptions of assurance service services performed by certified public accountants: Accounting education assessment applications

Date: August 2001
Creator: Brubaker, Thomas F.
Description: The overall purpose of this study was to examine how Certified Public Accountants (CPAs) perceive the potential use of assurance services to assess quality in accounting education programs. Survey questionnaires were mailed to a random sample of 250 CPAs in the north central Texas area. The questionnaire was designed to obtain demographic information and information relating to the respondents' perceptions of quality assessment of accounting education programs. An analysis of the results of this study suggest the following: CPAs consider (1) certain established criteria, such as SAT scores and faculty-to-student ratios, as effective measures for assessing quality attributes in accounting education programs and (2) traditional measures currently used for quality assessment in accounting education programs as only moderately effective by CPAs. CPAs are apparently seeking increased involvement with accounting education quality assessment and formulation of educational standards. They view the potential application of assurance services to accounting education quality as a way to offer a wider range of services to the public. CPAs perceive assurance services as a type of quality assessment that can be used to complement, but not replace, some of the more effective traditional methods, and as a way of enhancing the quality assessment process for accounting ...

Percussion scoring and orchestration in the wind and percussion ensemble literature of Jared Spears and David Gillingham

Percussion scoring and orchestration in the wind and percussion ensemble literature of Jared Spears and David Gillingham

Date: August 2001
Creator: White, Marc M.
Description: While many composers of wind ensemble literature have utilized percussion extensively in their compositions, Jared Spears and David Gillingham are renowned wind ensemble composers who have also written specifically for the percussion ensemble. Within their writing, both have exploited percussion through innovative scorings and their interest in rhythm, timbre, and density. The purpose of this study is to explore the scoring practices (functions of the instruments and combinations) and orchestration techniques (rhythmic and density relationships) of both composers, focusing on the manner and extent to which percussion is employed in their wind and percussion ensemble literature. The criteria for examining each piece and genre were developed to compare and contrast each composer's scoring and orchestration characteristics. To this end, each piece and genre was examined through several scoring categories designed to analyze overall ensemble relationships as well as individual functions of the percussion instruments. These categories were also applied to sections of music, focusing specifically on combinations of instruments and the relationship of ensemble choirs in separate and combined roles. Finally, percussion orchestration was examined with respect to motives, rhythmic underpinnings, metric usage, density relationships, and the significance of these elements to structural unity and form. These comparisons showed that, ...

The Pettis Integral and Operator Theory

The Pettis Integral and Operator Theory

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Huettenmueller, Rhonda
Description: Let (Ω, Σ, µ) be a finite measure space and X, a Banach space with continuous dual X*. A scalarly measurable function f: Ω→X is Dunford integrable if for each x* X*, x*f L1(µ). Define the operator Tf. X* → L1(µ) by T(x*) = x*f. Then f is Pettis integrable if and only if this operator is weak*-to-weak continuous. This paper begins with an overview of this function. Work by Robert Huff and Gunnar Stefansson on the operator Tf motivates much of this paper. Conditions that make Tf weak*-to-weak continuous are generalized to weak*-to­weak continuous operators on dual spaces. For instance, if Tf is weakly compact and if there exists a separable subspace D X such that for each x* X*, x*f = x*fχDµ-a.e, then f is Pettis integrable. This nation is generalized to bounded operators T: X* → Y. To say that T is determined by D means that if x*| D = 0, then T (x*) = 0. Determining subspaces are used to help prove certain facts about operators on dual spaces. Attention is given to finding determining subspaces far a given T: X* → Y. The kernel of T and the adjoint T* of T are used ...
