Understanding ecosystems

Understanding ecosystems

Date: 2003
Creator: British Antactic Survey
Description: Plants and animals live in environments which change over different periods of time. Some changes happen each year with the seasons, whilst others take hundreds or even millions of years. As these changes occur, living organisms respond in different ways. To cope with the changing seasons, individuals can change their physiology or behaviour, for instance by hibernating or migration. In response to longer-scale change, species may adapt through evolutionary change. If they cannot, they must either move away or become extinct.

Afterward: Making Meaning After a Frightening Near-Death Experience

Afterward: Making Meaning After a Frightening Near-Death Experience

Date: Winter 2002
Creator: Bush, Nancy Evans
Description: Abstract: The routes by which individuals attribute meaning to a near-death experience (NDE) appear to be similar, whether the experience was radiant or terrifying. This article explores three such avenues in relation to frightening experiences. I argue that resisting a terrifying NDE is likely to intensify fearfulness in an individual, and also that a similar effect occurs within society when this type of experience is resisted and misunderstood. The article concludes with an approach to synthesis and suggested techniques that may be useful in integrating the experience.

Abstract Moments of Art Found in the Ordinary

Abstract Moments of Art Found in the Ordinary

Date: December 2002
Creator: Kraft, Stuart
Description: This paper is an experiment using digital video to locate and identify the abstract in everyday life and nature. The abstract moment occurs when the image that is captured by video loses its connection with the original context, allowing the images to be viewed in an entirely new way. The abstract moment is initiated by a transformative instant, that instant in which perception is altered and the viewer sees the intended content of composition of light and sound. The project contains four digital videos that record the artist's progress and interests.

Analysis Of Sequential Barycenter Random Probability Measures via Discrete Constructions

Analysis Of Sequential Barycenter Random Probability Measures via Discrete Constructions

Date: December 2002
Creator: Valdes, LeRoy I.
Description: Hill and Monticino (1998) introduced a constructive method for generating random probability measures with a prescribed mean or distribution on the mean. The method involves sequentially generating an array of barycenters that uniquely defines a probability measure. This work analyzes statistical properties of the measures generated by sequential barycenter array constructions. Specifically, this work addresses how changing the base measures of the construction affects the statististics of measures generated by the SBA construction. A relationship between statistics associated with a finite level version of the SBA construction and the full construction is developed. Monte Carlo statistical experiments are used to simulate the effect changing base measures has on the statistics associated with the finite level construction.

An Annotated Bibliography of Mobile Agents in Networks

An Annotated Bibliography of Mobile Agents in Networks

Date: December 2002
Creator: Sriraman, Sandhya
Description: The purpose of this thesis is to present a comprehensive colligation of applications of mobile agents in networks, and provide a baseline association of these systems. This work has been motivated by the fact that mobile agent systems have been deemed proficuous alternatives in system applications. Several mobile agent systems have been developed to provide scalable and cogent solutions in network-centric applications. This thesis examines some existing mobile agent systems in core networking areas, in particular, those of network and resource management, routing, and the provision of fault tolerance and security. The inherent features of these systems are discussed with respect to their specific functionalities. The applicability and efficacy of mobile agents are further considered in the specific areas mentioned above. Although an initial foray into a collation of this nature, the goal of this annotated bibliography is to provide a generic referential view of mobile agent systems in network applications.

Approaches to Nature Aesthetics: East Meets West

Approaches to Nature Aesthetics: East Meets West

Date: December 2002
Creator: Toyoda, Mitsuyo
Description: Nature aesthetics is examined as an approach to environmental ethics. The characteristics of proper nature appreciation show that every landscape can be appreciated impartially in light of the dynamic processes of nature. However, it is often claimed that natural beauty decreases if humans interfere into nature. This claim leads to the separation of human culture and nature, and limits the number of landscapes which can be protected in terms of aesthetic value. As a solution to this separation, a non-dualistic Japanese aesthetics is examined as a basis for the achievement of the coexistence of culture and nature. Ecological interrelationships between human culture and nature are possible by means of an aesthetic consciousness in terms of non-hierarchical attitudes.

Assessing the Effect of Inquiry-Based Professional Development on Science Achievement Tests Scores.

Assessing the Effect of Inquiry-Based Professional Development on Science Achievement Tests Scores.

Date: December 2002
Creator: Dickson, Teresa K.
Description: This study analyzed student test scores to determine if teacher participation in an inquiry-based professional development was able to make a statistically significant difference in student achievement levels. Test scores for objectives that assessed the critical thinking skills and problem-solving strategies modeled in a science inquiry institute were studied. Inquiry-based experiences are the cornerstones for meeting the science standards for scientific literacy. State mandated assessment tests measure the levels of student achievement and are reported as meeting minimum expectations or showing mastery for specific learning objectives. Students test scores from the Texas Assessment of Academic Skills Test (TAAS) for 8th grade science and the Biology End Of Course (EOC) exams were analyzed using ANCOVA, Chi Square, and Logistic Regression, with the Iowa Test of Basic Skills (ITBS) 7th Grade Science Subtest as covariate. It was hypothesized that the students of Inquiry Institute teachers would have higher scale scores and better rates of mastery on the critical thinking objectives than the students of non-Institute teachers. It was also hypothesized that it would be possible to predict student mastery on the objectives that assessed critical thinking and problem solving based on Institute participation. This quasi-experimental study did not show a statistically significant ...

An Assessment of the Parent Orientation Program at the University of North Texas

An Assessment of the Parent Orientation Program at the University of North Texas

Date: December 2002
Creator: With, Elizabeth
Description: Although most institutions offer a parent program option to the orientation program, there has been little formalized research into the quality, planning or programming of parent orientation. There has been very little research into the impact parent orientation has on parents and whether or not they feel that such programs have met their needs, particularly by gender, minority status, educational background, or by geographic distance from the institution. This study seeks to determine the effectiveness of the parent orientation program at the University of North Texas to the parents who participate in this program. The study attempts to measure whether parents feel that they have adequate information about the institution to adequately support their student through the college transition; if parents feel welcomed by the UNT campus community; and if they feel that they have developed resources and institutional contacts that may be useful in the future in assisting their child to have a successful college experience at UNT. The study, conducted in the summer of 2002, had 736 respondents. An instrument developed to determine parent's perceptions of the effectiveness of the parent orientation program consisted of 31 questions using a Likert scale. A t-Test was utilized to analyze the ...

Automatic Software Test Data Generation

Automatic Software Test Data Generation

Access: Use of this item is restricted to the UNT Community.
Date: December 2002
Creator: Munugala, Ajay Kumar
Description: In software testing, it is often desirable to find test inputs that exercise specific program features. Finding these inputs manually, is extremely time consuming, especially, when the software being tested is complex. Therefore, there have been numerous attempts automate this process. Random test data generation consists of generating test inputs at random, in the hope that they will exercise the desired software features. Often the desired inputs must satisfy complex constraints, and this makes a random approach seem unlikely to succeed. In contrast, combinatorial optimization techniques, such as those using genetic algorithms, are meant to solve difficult problems involving simultaneous satisfaction of many constraints.

Bandanna, An Opera by Daron Aric Hagen with Libretto by Paul Muldoon, Commissioned by the College Band Directors National Association: The Origins of an Artwork with a Glimpse at its Musical Character Development

Date: December 2002
Creator: Powell, Edwin C.
Description: All information for this study was obtained by original source documents, interviews with the principal participants and the personal observations of the writer. A complete transcript of interviews with Daron Aric Hagen Michael Haithcockand Robert De Simone are included as appendices. In1961 the College Band Directors National Association (CBDNA) created its commissioning project for the purpose of contracting prominent composers to contribute works of high quality to the growing wind repertoire. Recently, CBDNA commissioned works that sought to collaborate with other disciplines within the artistic community. These collaborative works added new depth to the wind repertoire and helped advance the genre to new levels of prominence. CBDNA commissioned Daron Aric Hagen to write an opera using winds in the pit. He titled the work Bandanna, based on Shakespeare's Othello. Hagen contracted Paul Muldoon to write the libretto. A consortium of 79 member schools contributed to the project. A total of $100,000.00 was paid to the composer. The Director of Bands at Baylor University conducted the premiere performance of Bandanna during the 1999 CBDNA convention on 25 February 1999. Hagen assigned instrumental, thematic and harmonic attributes to each character. There are literally thousands of interactions between these elements that weave a ...

Beyond GNP: Economic Freedom as a Determinant of Basic Human Needs.

Beyond GNP: Economic Freedom as a Determinant of Basic Human Needs.

Date: December 2002
Creator: Juenke, Eric
Description: Research concerning ‘basic needs' in the Human Rights literature has consistently found a positive and significant relationship between measures of wealth and basic needs provision. This study utilizes a relatively new measure of economic freedom to test hypotheses regarding general macro-economic policy decisions and basic needs outcomes. A pooled dataset of 138 countries over four years is examined using OLS panel regression controlling for both' year' and ‘country,' in a standard basic needs model. Consistent and systematic differences between economic freedom effects in OECD nations and non-OECD nations are revealed. The Economic Freedom Index has both theoretical and empirical advantages over previous measures of wealth and economic freedom, allowing human rights scholars to test specific economic policy decisions as they affect basic needs outcomes.

Cognitive and Perceptual-Motor Indicators of Lateralized vs. Diffuse Brain Damage in Adults.

Cognitive and Perceptual-Motor Indicators of Lateralized vs. Diffuse Brain Damage in Adults.

Access: Use of this item is restricted to the UNT Community.
Date: December 2002
Creator: Gregory, Erin Kathleen Taylor
Description: Among the goals of the neuropsychological assessment are to detect the presence of brain damage, localize which areas of the brain may be dysfunctional and describe subsequent functional impairments. The sensitivity of neuropsychological instruments in carrying out these functions is a question of some debate. The purpose of this study is to determine the utility of lateralizing indicators from the WAIS-III, McCarron Assessment of Neuromuscular Development (MAND) and Haptic Visual Discrimination Test (HVDT), from the McCarron-Dial System Neuropsychological Assessment Battery (MDS), in ascertaining the presence or absence of brain damage as well as location of lesion. The classification accuracies of using performance level indicators from these tests and lateralizing indicators, alone and together, were compared.

A Common Representation Format for Multimedia Documents

A Common Representation Format for Multimedia Documents

Date: December 2002
Creator: Jeong, Ki Tai
Description: Multimedia documents are composed of multiple file format combinations, such as image and text, image and sound, or image, text and sound. The type of multimedia document determines the form of analysis for knowledge architecture design and retrieval methods. Over the last few decades, theories of text analysis have been proposed and applied effectively. In recent years, theories of image and sound analysis have been proposed to work with text retrieval systems and progressed quickly due in part to rapid progress in computer processing speed. Retrieval of multimedia documents formerly was divided into the categories of image and text, and image and sound. While standard retrieval process begins from text only, methods are developing that allow the retrieval process to be accomplished simultaneously using text and image. Although image processing for feature extraction and text processing for term extractions are well understood, there are no prior methods that can combine these two features into a single data structure. This dissertation will introduce a common representation format for multimedia documents (CRFMD) composed of both images and text. For image and text analysis, two techniques are used: the Lorenz Information Measurement and the Word Code. A new process named Jeong's Transform is ...

Comparative biochemistry and genetic analysis of nucleoside hydrolase in  Escherichia coli,  Pseudomonas aeruginosa, and  Pseudomonas fluorescens.

Comparative biochemistry and genetic analysis of nucleoside hydrolase in Escherichia coli, Pseudomonas aeruginosa, and Pseudomonas fluorescens.

Date: December 2002
Creator: Fields, Christopher J.
Description: The pyrimidine salvage enzyme, nucleoside hydrolase, is catalyzes the irreversible hydrolysis of nucleosides into the free nucleic acid base and D-ribose. Nucleoside hydrolases have varying degrees of specificity towards purine and pyrimidine nucleosides. In E. coli, three genes were found that encode homologues of several known nucleoside hydrolases in protozoa. All three genes (designated yaaF, yeiK, and ybeK) were amplified by PCR and cloned. Two of the gene products (yeiK and ybeK) encode pyrimidine-specific nucleoside hydrolases, while the third (yaaF) encodes a nonspecific nucleoside hydrolase. All three were expressed at low levels and had different modes of regulation. As a comparative analysis, the homologous genes of Pseudomonas aeruginosa and P. fluorescens (designated nuh) were cloned. Both were determined to encode nonspecific nucleoside hydrolases. The nucleoside hydrolases of the pseudomonads exhibited markedly different modes of regulation. Both have unique promoter structures and genetic organization. Furthermore, both pseudomonad nucleoside hydrolase were found to contain an N-terminal extension of 30-35 amino acids that is shown to act as a periplasmic-signaling sequence. These are the first two nucleoside hydrolases, to date,that have been conclusively demonstrated to be exported to the periplasmic space. The physiological relevance of this is explained.

A Comparison of Auditory and Visual Stimuli in a Delayed Matching to Sample Procedure with Adult Humans.

A Comparison of Auditory and Visual Stimuli in a Delayed Matching to Sample Procedure with Adult Humans.

Date: December 2002
Creator: DeFulio, Anthony L.
Description: Five humans were exposed to a matching to sample task in which the delay (range = 0 to 32 seconds) between sample stimulus offset and comparison onset was manipulated across conditions. Auditory stimuli (1” tone) and arbitrary symbols served as sample stimuli for three (S1, S2, S3) and two (S4 and S5) subjects, respectively. Uppercase English letters (S, M, and N) served as comparison stimuli for all subjects. Results show small but systematic effects of the retention interval on accuracy and latency to selection of comparison stimuli. The results fail to show a difference between subjects exposed to auditory and visual sample stimuli. Some reasons for the failure to note a difference are discussed.
