An Infrared Study of some Ω-Phenyl and Ω-Benzoyl Alkanoic Acids
There is no available information in the literature on interaction between carboxyl hydrogen and ω-phenyl groups. Consequently, it was of interest to seek such interactions. Some form of interaction is evident from the study of the spectra of some phenylalkanoic acids and benzoyalkanoic acids.
Inherent Problems Associated with the Identification of Genes Responsible for Allowing B. cepacia to Adhere to Human Lung Carcinoma A549 Cells
Access: Use of this item is restricted to the UNT Community.
In this project a bacteria's ability to bind to human lung tissue was investigated. To carry out this study Pseudomonas aeruginosa, Eschericia coli and Burkholderia cepacia were used. B. cepacia served as the bacterium of interest. Isolating the gene which confers upon this bacterium the ability to bind to lung tissue was the main objective of this study. P. aeruginosa has been identified as being the bacteria most responsible for causing serious lung infections that can result in cystic fibrosis. This bacterium therefore served as the positive control in this study. On the contrary, E. coli does not possess this binding ability and served as the negative control. This paper gives a detailed outline of the different procedures necessary for the successful completion of this project. Firstly, a broad guideline of the important steps involved are explored. This is followed by a discussion on potential problems and possible solutions. Throughout the document, illustrations of expected results are indicated so as to further guide the researcher.

Inhibition of Return in Schizophrenia
The present study was designed to look at inhibition of return within a schizophrenic population for the first time. Inhibition of return is an attentional phenomenon that has been studied with a number of populations, and has been shown to be present in normal individuals. Based on the disattention hypothesis put forth by Cromwell and colleagues (e.g., Cromwell & Dokecki, 1968), it was hypothesized that patients with schizophrenia would show an impaired inhibition of return. Twenty-eight inpatients with schizophrenia, and 19 normal comparisons were evaluated on a visual inhibition of return task. Consistent with hypotheses, schizophrenia patients have significant impairments in inhibition of return compared to normal comparison participants. Further, the relative lack of inhibition of return in the schizophrenic group was found to be strongest to stimuli in the left visual field. These results provide initial support for a reconceptualization of the disattention hypothesis.

Innovation Teams: an Empirical Examination of the Relationship of Team Climate and Development Strategies in Consumer Packaged Goods Industries
Companies’ new primary source for sustainable revenue growth comes from creating new innovations, rather than from mergers and acquisitions. Companies are finding it difficult to align internal support for the innovative creativity of teams with standard operating procedures. This research aims to discover how innovative teams contribute to forming development strategies that CPG firms use to create new products. Dimensions of the Theory of Team Climate in Innovation (TTCI) offer insight on the dimensions of development strategy. Specifically, by integrating the theories, a proposed model identifies the innovation team’s impact on the firm’s development strategies. Such understanding has the potential to increase firm profits, lower innovation costs, increase innovation speed, and support innovation training. To empirically test this model, employees responsible for product development in the consumer packaged goods (CPG) industries were surveyed. Structural modeling techniques were used to analyze the data. Findings indicate support for using TTCI to explain the compressed development strategy. Theoretical contributions include: 1) extending TTCI and its associated measures into tangible products industries, 2) refining and adding to TTCI measures, 3) extending the development strategies theory into tangible products industries, and 4) adding to the measures for development strategy. Future research appears fertile for methods and measures used in this study, and managers in CPG will benefit from an enhanced understanding of how to better structure innovation teams in alignment with a firm’s development strategy.

An Inquiry into the Factors Affecting the Outcome of the 1948 Presidential Election with the Situations in the States of Illinois, Ohio, and California Subject to Special Emphasis
This thesis examines the factors affecting the outcome of the 1948 presidential election. The factors which will be take up are not a complete list of all those influences on the election but will be those which appeared most frequently in writings on the subject and those which, in the writer's opinion, exerted the strongest influence. By combining specific studies of the tree large pivotal states, with the investigation of general factors affecting the election, it is believed that certain rather definite conclusions can be drawn concerning what happened in the country as a whole.

Inside the Third Sector: a Gongo Level Analysis of Chinese Civil Society
This thesis investigates a new variant of the relationship between society and the states: Government-Owned (or Organized) Non-Governmental Organizations (GONGOs). Past research has typically understood civil society as a means to explain the orientation of groups of citizens towards collective outcomes. For decades, NGOs have been a key component of this relationship between political actors but the systematic study of GONGOs has been widely neglected by research. I used an original dataset collected from an NGO directory developed by the China Development Brief (CDB) that provides information on the functional areas of NGOs, their sources of funding and various organizational facts. These data were used to code a series of concepts that will serve as the basis for an initial systematic study into GONGOs and their relationship with the Chinese government. My theoretical expectations are that the primary predictors of an NGO’s autonomy relate to their functional areas of operation, their age and other geographical factors. I find preliminary support for the effect of an NGO’s age on its autonomy from the state, as well as initial support for the dynamic nature of the relationship between NGOs and the state. I close with a discussion of these findings as well as their implications for future research.
Insight versus Desensitization: a Comparative Study
The present study was an attempt to show that the behavioral technique of desensitization is superior to insight-oriented psychotherapy in terms of not only behavior change for individuals undergoing desensitization but in terms of case of acquisition to novice therapists who have virtually no clinical experience.
Installation and Manufacturing of Photovoltaics: an Assessment Using California and New York
Renewable energy studies are becoming increasingly important as world energy demand rises and current energy sources are increasingly questioned. Solar photovoltaics (PV) are the focus of this study as a renewable industry still in its infancy. This research examines the geography of solar panel installation and manufacturing from 2007 to 2010 in California and New York. California is the larger of the two markets and has implemented more policy support; programs that appear to have increased the pace of installations, reduce the size of the subsidy, and help lower total costs. Similar trends are observable in New York. US based companies are still making solar panels, but foreign competitors, most notably from China and Mexico, are capturing an increasing share of the market.

The problem of this study was to determine the effectiveness of instant replay television as a method for teaching certain physical aspects of choral conducting to undergraduate college or university students majoring in music education.
Instigating a Necessary Epiphany in Visual Message-Making for Design Educators and Future Communication Designers
Access: Use of this item is restricted to the UNT Community.
Man has used graphic signs and symbols to express a variety of thoughts and feelings since before the invention of writing; they have helped him to preserve the ideologies that have enabled him to articulate his conception of the world. Every culture in every historical era has invested the objects, animals and plants around it with a multitude of different psychological meanings to communicate its essential belief systems and social aspirations. In my document, I chose to shed light on the responsibility I believe design educators must assume regarding their ability to understand and teach the importance of how similar graphic signs, symbols, ideograms and icons are perceived differently by different cultures in the hyper-connected, inter-global economy of 21st century. It is very crucial not to discount the influence and correlation of symbolic, fundamental building blocks of design with the basic psychological functions that inform our subconscious, and are also informed by our individual social and cultural upbringings. People from different cultures may cognate these shapes similarly, but they perceive and encode their meanings based on their particular social and cultural influences. One-size-fits-all communication design solutions rarely work, especially when they are distributed to culturally diverse audiences, because various ethnic audiences view the world and the visual messages that designers create for them through their own self-imposed cultural filters. These filters are informed by language, religion, politics and other shared experiences, and they go beyond what can be externally observed. As communication designers, we need to take the time to study and understand how these filters operate, so that we can accurately convey our clients' messages to the intended audiences so that they might be appropriately encoded and perceived.
Institutional Characteristics as Expressed in Selected Writings of Thomas Robert Malthus
This investigation is concerned primarily with describing some characteristics of the institutionalist school of economic theory and then relating these characteristics to the writings of Thomas Robert Malthus. Thus in the course of this thesis two distinct sections are developed: one describing what are felt to be the outstanding characteristics of institutionalism and the second relating these characteristics directly to Malthus.
Institutional Inbreeding among Mathematics Faculty in American Colleges and Universities
The purpose of this research was to estimate (1) the extent to which institutional inbreeding is prevalent among mathematics faculty at colleges and universities throughout the United States; (2) the extent of institutional inbreeding among mathematics faculty at American colleges and universities classified according to institutional genre; (3) the extent of institutional inbreeding among mathematics faculty classified according to gender; and (4) the extent of institutional inbreeding among mathematics faculty in American colleges and universities classified according to regions of the country. Institutional inbreeding was defined as faculty employment at the institution from which one received the highest earned degree. An exhaustive review of the literature on inbreeding was used to develop this research. All public-supported and private-supported American universities that offer a doctorate in mathematics were identified by consulting the 1991 American Mathematical Society Professional Directory. Catalogs for the academic year 1991-1992 were requested from each institution. One-hundred sixty-seven institutions of higher education which offer the Ph.D. degree in mathematics and 5,961 faculty members were identified. The results of the analyses found a mean proportion of inbred mathematics faculty of 3.46 percent, which is one-tenth of the most recent study examining mathematics faculty. A chi-square goodness of fit test using specified frequencies, found a statistically significant difference between rates of institutional inbreeding among mathematics stratified according to gender. A chi-square goodness of fit test using specified frequencies was used to test the association between mathematics faculty when stratified by Carnegie classification and regions of the country. No association was found between rates of institutional inbreeding of mathematics faculty when institutions were stratified according to the Carnegie classification and regions of the country. This research indicates institutional inbreeding is on the decline among mathematics faculty in American Colleges and Universities.
Institutional Misconduct Among Gang Related and Non-Gang Related Institutionalized Delinquents
The problems that gang members create within adult correctional facilities continue to receive attention in the literature. Gang members within juvenile institutions have received far less attention from researchers, and misconduct of these juveniles, both serious and non-serious, is relatively unexplored. This study explored the institutional misconduct of 4,309 male delinquents released from the Texas Youth Commission. Youths younger at commitment, those with a higher TYC risk score, and those youths with emotional problems were found more likely to commit both serious and non-serious institutional misconduct, regardless of gang membership. This thesis concludes with suggestions for additional research on gang members within juvenile institutions and the relationship of gang membership to institutional misconduct.
Institutional ownership and dividend policy: A framework based on tax clientele, information signaling and agency costs.
This study is an empirical examination of a new theory that links dividends to institutional ownership in a framework of both information signaling and agency costs. Under this theory put forth by Allen, Bernardo and Welch in 2000, dividends are paid out to attract tax-favored institutional investors, thereby signaling good firm quality and/or more efficient monitoring. This is based on the premise that institutions are considered sophisticated investors with superior ability and stronger incentive to be informed about the firm quality compared to retail investors. On the agency level, institutional investors display monitoring capabilities, and can detect and correct managerial pitfalls, thus their presence serves as an assurance that the firm will remain well run. The study provides a comprehensive analysis of the implications of the theory by testing various aspects of the relationship between dividends and institutional holdings. Unlike the prevalent literature on this topic, I give specific attention to the different types of institutional investors and their incentives to invest in dividend paying stocks. Moreover, I analyze the signaling and the agency effects on the market reaction to dividend initiations within the framework proposed by the theory. Finally, I test the smoothing effect institutions have on dividends by examining the firm's propensity to increase dividends given the level of institutional ownership. I find institutional holders to respond positively to dividend initiation announcements as they adjust their portfolios by buying or increasing their holdings of the dividend paying stock following the announcement. I also find that this response is displayed more strongly among tax-favored institutions. My test results also reveal that positive abnormal returns to dividend initiation announcements are a decreasing function of institutional holdings in the dividend initiating firm, and that this mitigating effect of institutional ownership on the market reaction to dividend initiations is stronger for firms with higher information asymmetry and more potential for agency problems. This evidence lends some degree of support to the tested theory. Additional support to lies in the test results of its smoothing hypothesis which reveal that as institutional ownership increases, the propensity of firms to increase dividends decreases.
Institutions and Drug Markets
This thesis examines how drug policy and enforcement affect drug manufacturers. The approach taken is a comparative institutional analysis of cannabis and methamphetamine production. I focus on the effects of prohibition, privacy, and clandestine markets on producer behavior for these two drugs and the unintended consequences that result. I demonstrate that cannabis and methamphetamine producers both face substantial transaction costs and that producers alter their behavior to manage these transaction costs. I conclude that cannabis producers can adopt indoor, small-scale operations to hide their activity, which are capable of yielding continuous, high-potency crops. Methamphetamine producers also adopt small-scale, decentralized strategies, but commodity control increases their exposure and leads to greater overall transaction costs during the manufacturing process.
Instruction in Composition through Small-Group Activities for Secondary Students
It is the purpose of this thesis to describe various small-group activities which could be used in classes of secondary English to help to "teach-Johnny-to-write." These activities are divided into four areas of study--developing and practicing specific skills related to writing, developing a topic, planning a theme, and evaluating student writing.
An Instructional Approach to Introducing Twentieth-century Piano Music to Piano Students From Beginning to Advanced Levels: a Graded Repertoire for Mastering the Challenges Posed by Logan Skelton’s Civil War Variations
Beginning and intermediate piano students typically study the repertoire of the eighteenth and nineteenth centuries. This pedagogical approach leaves them underprepared to approach compositions written since the latter part of the twentieth-century which are significantly different in terms of harmony, rhythm, meter, and compositional procedure. Therefore, a step-by-step method is necessary to prepare a student for the challenges of learning twentieth and twenty-first century piano music. Civil War Variations (1988), by Logan Skelton, is an excellent example of a piece that presents a number of challenges characteristically found in late twentieth-century piano music. The twenty-five variations that comprise the work incorporate a series of twentieth-century musical techniques, namely complex rhythms, extreme dissonance, frequent metric changes, dissonant counterpoint, the inclusion of blues scales and rhythms, and new notations. The purpose of this study is to identify the technical, musical, structural and notational challenges posed by a work such as Logan Skelton’s Civil War Variations; examination of this piece will lead to suggestions regarding repertoire that a teacher may assign to beginning, intermediate, and advanced students in order to prepare them logically and in a step-by-step fashion to cope with and meet the challenges posed by this and other compositions having similar characteristics.
Instructional Effectiveness of an Integrated Holistic Teaching Method of German Language at the Community College Level
Access: Use of this item is restricted to the UNT Community.
The propose of this study was to determine the effectiveness and appropriateness of the integrated holistic method for teaching grammatical structure, cultural norms and behavior, writing and listening skills to beginning German language students. The study examined a sample of undergraduate students who were enrolled in the introductory college level German offered at the Collin County Community College, Spring Creek Campus in Plano, Texas. A total of 24 students participated in this study. This study utilized a pre- and posttest group to measure the instructional effectiveness of the integrated holistic teaching method. Structural grammar, cultural norms and behavior, writing, and listening skills were used as dependent variables. The holistic integrated teaching method were measured at the end of the course as independent variables. Individual pre- and posttests were used for each of the dependent variables. The higher posttest mean scores indicated significant improvement in student learning level in four major language skills such as structural grammar, cultural norms and behavior, writing, and listening through the holistic integrated teaching method.
Instructional Leadership Responsibilities of Assistant Principals in Large Texas High Schools
The purpose of this study was to determine the extent secondary assistant principals in large Texas high schools demonstrate behaviors consistent with what the literature describes as instructional leadership. Three hundred seventy principals and assistant principals of large Texas high schools participated in this study. The Principal Instructional Management Rating Scale (Hallinger, 1987) was used to quantify instructional leadership in 10 different job functions. The study found that (a) assistant principals perceive themselves as exhibiting instructional leadership behaviors at a high frequency, (b) principals perceive their assistant principals exhibiting instructional leadership behaviors at a high frequency, (c) the perceptions of the principals and assistant principals were similar, and (d) principals and assistant principals reported more engagement in instructional leadership responsibilities and felt more pressured over the last five years under the new accountability and rating requirements of No Child Left Behind and the state assessments. These findings suggested that the administrative roles and responsibilities in high schools should be restructured to allow assistant principals to focus on instructional leadership.
Instructor immediacy and presence in the online learning environment: An investigation of relationships with student affective learning, cognition, and motivation.
Bivariate correlation was used to examine possible relationships between instructor immediacy and instructor presence, and a statistically significant correlation was found. Multiple linear regression analysis was used to determine whether the linear combination of instructor immediacy and presence caused significant variance in student affective learning, cognition, and motivation. For all three of the latter dependent variables, the linear combination of instructor immediacy and presence was found to cause statistically significant variance. However, although the overall regression models were significant in all three tests, instructor immediacy was not found to be a significant individual predictor for causing variance in affective learning, cognition, or motivation, whereas instructor presence was found to be a significant individual predictor of all three. Finally, factorial ANOVA revealed that, for perceptions of instructor immediacy, only classification and course type were found to explain significant variance, with undergraduate students in asynchronous courses reporting significantly lower instructor immediacy. For perceptions of instructor presence, graduate students tended to rate their instructors as having higher presence than did undergraduate students, and students in synchronous courses tended to rate their instructors as having higher presence than did students in asynchronous courses.

An Instrument to Determine whether Certain Fundamental Philosophical and Educational Beliefs Are Held by Selected Public School Teachers in the Areas of Elementary Education, Secondary Education, and Guidance
The problem of this study was to develop an instrument which would reveal whether certain fundamental philosophical and educational beliefs are held by public school teachers in the areas of elementary education, secondary education, and guidance.
The Instrumental Music of Ida Gotkovsky: Finding Intertextual Meaning
Ida Gotkovsky, a student of Olivier Messiaen and Nadia Boulanger, composed for nearly every instrument, voice, and ensemble. Although Gotkovsky's Concerto for Trombone is a monumental work for the trombone it is rarely performed and recordings are scarce. There is a general lack of scholarly attention to the music of Ida Gotkovsky, however, the technical and aesthetic quality of her music merits further examination. Previous studies of Gotkovsky's music focused on the analysis of individual compositions. However, much more can be learned by examining a work within the context of her general compositional output. Gotkovsky's compositional style includes extensive musical self-borrowing. The goal of this project is to demonstrate melodic and textural similarities and differences within her music to inform performance practice and to establish interest in her music. The context in which Gotkovsky reuses her music is significant and can provide additional musical insight. An informed awareness of her extensive use of self-quotation familiarizes the performer with her compositional language in a variety of musical settings. Such familiarity with her musical style leads to an improved and artistically educated performance.
Intangible Qualities of Rare Books: Toward a Decision-Making Framework for Preservation Management in Rare Book Collections, Based Upon the Concept of the Book as Object
For rare book collections, a considerable challenge is involved in evaluating collection materials in terms of their inherent value, which includes the textual and intangible information the materials provide for the collection's users. Preservation management in rare book collections is a complex and costly process. As digitization and other technological advances in surrogate technology have provided new forms representation, new dilemmas in weighing the rare book's inherently valuable characteristics against the possibly lesser financial costs of surrogates have arisen. No model has been in wide use to guide preservation management decisions. An initial iteration of such a model is developed, based on a Delphi-like iterative questioning of a group of experts in the field of rare books. The results are used to synthesize a preservation management framework for rare book collections, and a small-scale test of the framework has been completed through two independent analyses of five rare books in a functioning collection. Utilizing a standardized template for making preservation decisions offers a variety of benefits. Preservation decisions may include prioritizing action upon the authentic objects, or developing and maintaining surrogates in lieu of retaining costly original collection materials. The framework constructed in this study provides a method for reducing the subjectivity of preservation decision-making and facilitating the development of a standard of practice for preservation management within rare book collections.
The Integral Role of Training in the Implementation of Hate Crime Legislation
This research focuses on the association between law enforcement training and implementation of hate crime legislation. The Anti-Defamation League's state hate crime statutory provisions and the Federal Bureau of Investigation's Hate Crime Reporting by States data are examined. Section one includes the following: What Constitutes Hate?, The History of Hate Crime Legislation, and Issues Facing Hate Crime Legislation. Section two surveys literature on both Hate Crime Legislation and the training of law enforcement officers. Section three discusses the Anti-Defamation League and FBI data in detail and explains the methods used to test the association between law enforcement training and reporting of hate crime legislation. Findings yield a statistically significant association between law enforcement training and reporting of hate crime legislation.
Integrals Defined on a Field of Sets
The purpose of this paper is to define an integral for real-valued functions which are defined on a field of sets and to demonstrate several properties of such an integral.
An Integrated Approach to Determine Phenomenological Equations in Metallic Systems
It is highly desirable to be able to make predictions of properties in metallic materials based upon the composition of the material and the microstructure. Unfortunately, the complexity of real, multi-component, multi-phase engineering alloys makes the provision of constituent-based (i.e., composition or microstructure) phenomenological equations extremely difficult. Due to these difficulties, qualitative predictions are frequently used to study the influence of microstructure or composition on the properties. Neural networks were used as a tool to get a quantitative model from a database. However, the developed model is not a phenomenological model. In this study, a new method based upon the integration of three separate modeling approaches, specifically artificial neural networks, genetic algorithms, and monte carlo was proposed. These three methods, when coupled in the manner described in this study, allows for the extraction of phenomenological equations with a concurrent analysis of uncertainty. This approach has been applied to a multi-component, multi-phase microstructure exhibiting phases with varying spatial and morphological distributions. Specifically, this approach has been applied to derive a phenomenological equation for the prediction of yield strength in a+b processed Ti-6-4. The equation is consistent with not only the current dataset but also, where available, the limited information regarding certain parameters such as intrinsic yield strength of pure hexagonal close-packed alpha titanium.
An Integrated Architecture for Ad Hoc Grids
Extensive research has been conducted by the grid community to enable large-scale collaborations in pre-configured environments. grid collaborations can vary in scale and motivation resulting in a coarse classification of grids: national grid, project grid, enterprise grid, and volunteer grid. Despite the differences in scope and scale, all the traditional grids in practice share some common assumptions. They support mutually collaborative communities, adopt a centralized control for membership, and assume a well-defined non-changing collaboration. To support grid applications that do not confirm to these assumptions, we propose the concept of ad hoc grids. In the context of this research, we propose a novel architecture for ad hoc grids that integrates a suite of component frameworks. Specifically, our architecture combines the community management framework, security framework, abstraction framework, quality of service framework, and reputation framework. The overarching objective of our integrated architecture is to support a variety of grid applications in a self-controlled fashion with the help of a self-organizing ad hoc community. We introduce mechanisms in our architecture that successfully isolates malicious elements from the community, inherently improving the quality of grid services and extracting deterministic quality assurances from the underlying infrastructure. We also emphasize on the technology-independence of our architecture, thereby offering the requisite platform for technology interoperability. The feasibility of the proposed architecture is verified with a high-quality ad hoc grid implementation. Additionally, we have analyzed the performance and behavior of ad hoc grids with respect to several control parameters.
Integrated Computational and Experimental Approach to Control Physical Texture During Laser Machining of Structural Ceramics
The high energy lasers are emerging as an innovative material processing tool to effectively fabricate complex shapes on the hard and brittle structural ceramics, which previously had been near impossible to be machined effectively using various conventional machining techniques. In addition, the in-situ measurement of the thermo-physical properties in the severe laser machining conditions (high temperature, short time duration, and small interaction volume) is an extremely difficult task. As a consequence, it is extremely challenging to investigate the evolution of surface topography through experimental analyses. To address this issue, an integrated experimental and computational (multistep and multiphysics based finite-element modeling) approach was employed to understand the influence of laser processing parameters to effectively control the various thermo-physical effects (recoil pressure, Marangoni convection, and surface tension) during transient physical processes (melting, vaporization) for controlled surface topography (surface finish). The results indicated that the material lost due to evaporation causes an increase in crater depth of machined cavity, whereas liquid expulsion created by the recoil pressure increases the material pileup height around the lip of machined cavity, the major attributes of surface topography (roughness). Also, it was found that the surface roughness increased with increase in laser energy density and pulse rate (from 10 to 50Hz), and with the decrease in distance between two pulses (from 0.6 to 0.1mm) or the increase in lateral and transverse overlap (0, 17, 33, 50, 67, and 83%). The results of the computational model are also validated by experimental observations with reasonably close agreement.
An Integrated Guidance Program for Small Secondary Schools in Texas
Of the 1190 four-year high schools of Texas there are 941 with an enrollment of 250 or less. This group of schools is missing many opportunities to guide the youth they graduate into effective and wholesome living by means of an integrated guidance program. It is the purpose of this study to develop a program which, if incorporated into the curricula of these schools, should result in an integration of guidance into the many phases of the school's activities and increase the school's usefulness to the student.
Integrating Art with Other Subjects in a Fifth Grade of the Robert E. Lee School in Denton, Texas
The purpose of this study was threefold: (1) to develop an integrative program using art as its core which was put into effect in one of two fifth grades in the Robert E. Lee School in Denton, Texas, (2) to develop criteria for evaluating an art program used as an integrating agent, and (3) to evaluate the program in terms of the criteria and in outcomes in achievement in subject matter.
Integrating Concepts in Modern Molecular Biology into a High School Biology Curriculum
Access: Use of this item is restricted to the UNT Community.
More so than any other science in the past several decades, Biology has seen an explosion of new information and monumental discoveries that have had a profound impact on much more than the science itself. Much of this has occurred at the molecular level. Many of these modern concepts, ideas, and technologies, as well as their historical context, can be easily understood and appreciated at the high school level. Moreover, it is argued here that the integration of this is critical for making biology relevant as a modern science. A contemporary high school biology curriculum should adequately reflect this newly acquired knowledge and how it has already has already begun to revolutionize medicine, agriculture, and the study of biology itself. This curriculum provides teachers with a detailed framework for integrating molecular biology into a high school biology curriculum. It is not intended to represent the curriculum for an entire academic year, but should be considered a significant component. In addition to examining key concepts and discoveries, it examines modern molecular techniques, their applications, and their relevance to science and beyond. It also provides several recommended labs and helpful protocols.

Integrating GIS with Benthic Metrics: Calibrating a Biotic Index to Effectively Discriminate Stream Impacts in Urban Areas of the Blackland Prairie Eco-Region
Rapid Bioassessment Protocols integrate a suite of community, population, and functional metrics, determined from the collection of benthic macroinvertebrates or fish, into a single assessment. This study was conducted in Dallas County Texas, an area located in the blackland prairie eco-region that is semi-arid and densely populated. The objectives of this research were to identify reference streams and propose a set of metrics that are best able to discriminate between differences in community structure due to natural variability from those caused by changes in water quality due to watershed impacts. Using geographic information systems, a total of nine watersheds, each representing a different mix of land uses, were chosen for evaluation. A total of 30 metrics commonly used in RBP protocols were calculated. Efficacy of these metrics to distinguish change was determined using several statistical techniques. Ten metrics were used to classify study area watersheds according to stream quality. Many trends, such as taxa presence along habitat quality gradients, were observed. These gradients coincided with expected responses of stream communities to landscape and habitat variables.
Integrating life cycle analysis and the ecological footprint calculator to foster sustainable behaviors
Access: Use of this item is restricted to the UNT Community.
Many tools have been developed to assess global, national or regional sustainable development policies. However, as governments develop sustainable policies, individuals must also feel empowered to affect their personal impact on the planet. This thesis integrates three sustainability concepts that lend themselves to individual sustainability: The natural step, life cycle assessment, and the ecological footprint. TNS serves to provide the meaning and substance toward sustainable development. LCA helps provide the framework for assessing sustainability. The EF calculator determines the driving components and measures the qualitative decisions made through TNS and LCA. From the analysis of the household footprint calculator a simplified footprint calculator was developed to assist individuals and communities in setting benchmarks and goals as they move away from over-consumption and towards a sustainable lifestyle.
Integrating Selective Herbicide and Native Plant Restoration to Control Alternanthera philoxeroides (Alligator Weed)
Exotic invasive aquatic weeds such as alligator weed (Alternanthera philoxeroides) threaten native ecosystems by interfering with native plant communities, disrupting hydrology, and diminishing water quality. Development of new tools to combat invaders is important for the well being of these sensitive areas. Integrated pest management offers managers an approach that combines multiple control methods for better control than any one method used exclusively. In a greenhouse and field study, we tested the effects of selective herbicide application frequency, native competitor plant introduction, and their integration on alligator weed. In the greenhouse study, alligator weed shoot, root, and total biomass were reduced with one herbicide application, and further reduced with two. Alligator weed cumulative stem length and shoot/root ratio was only reduced after two applications. In the greenhouse, introduction of competitors did not affect alligator weed biomass, but did affect shoot/root ratio. The interaction of competitor introduction and herbicide did not significantly influence alligator weed growth in the greenhouse study. In the field, alligator weed cover was reduced after one herbicide application, but not significantly more after a second. Introduction of competitor species had no effect on alligator weed cover, nor did the interaction of competitor species and herbicide application. This study demonstrates that triclopyr amine herbicide can reduce alligator weed biomass and cover, and that two applications are more effective than one. To integrate selective herbicides and native plant introduction successfully for alligator weed control, more research is needed on the influence competition can potentially have on alligator weed growth, and the timing of herbicide application and subsequent introduction of plants.
The Integration of a Fifth-Grade Curriculum Through Language-Arts Subjects in the Stonewall Jackson Elementary School, Denton, Texas.
As a result of the upheaval in educational theories and practices, many new philosophies and methods have appeared. Among them is the subject of integration in the elementary school curriculum. Much has been written regarding its meaning and application. An interest in the subject prompted the writer to choose as a thesis subject the problem of what could be done to integrate the fifth-grade curriculum through the language arts subjects in the Stonewall Jackson Elementary School, Denton, Texas.

Integration of field-based analysis of plant community dynamics with quantitative analysis of landscape change in the Ray Roberts Lake area, 1987—1997
This study focused on the effectiveness of integrating traditional plant community analyses with landscape ecological analyses based on remotely sensed data. A temporal analysis of plant community diversity was conducted for major plant communities of the Ray Roberts Lake area using transect monitoring data collected between 1987 and 1997. Landscape analyses were performed with FRAGSTATS*ARC using classified SPOT satellite imagery for 1987 and 1997. Although the methodology developed in this work was exploratory, it was found that characterizing the dynamics of major plant communities in the study area produced a more effective and insightful analysis of Ray Roberts Lake area landscape dynamics.
Integration of Students with Disabilities into a Contemporary Technology Education Program: a Case Study
The impacts resulting from the integration of students with moderate-to-severe disabilities into a contemporary technology education program are described in this study. The research centered around questions that addressed impacts on students with disabilities, on regular students, on teachers, and on parents of students with disabilities. The study took place in a ninth-grade technology education class and involved two students with moderate-to-severe disabilities. One subject was a 15-year-old male student who was autistic, had a speech handicap, and was mildly retarded. The other student was a 17-year-old male who was emotionally disturbed and learning disabled. Data were collected through classroom observations, videotaped sessions, and interviews with teachers and parents. Notes taken during observations and from videotaped sessions were transcribed, coded, and analyzed. Interviews were also transcribed. The transcripts were reviewed, and significant data were transferred to interview synopsis sheets for incorporation with the other findings. No major problems were found with the integration of the students with disabilities into the technology education program. The students with disabilities caused no discipline problems and were readily accepted by the regular students. However, because the students with disabilities were not actively involved in many of the activities of the class, much of their time was spent off task. The findings reveal that the technology education teacher, who was provided only minimal orientation prior to the placement of the students with disabilities in his class, used regular students as well as individual attention to direct the students with disabilities. A strong need for in-depth, ongoing communication was indicated between special education staff members and mainstream teachers. The importance of providing an orientation for regular students before students with disabilities are placed in mainstream classes was also evident from this study.
