A genomic clone containing a 16.9-kb segment of cotton DNA was found to encompass a D-12 fatty acid desaturases (FAD2-4) gene. The FAD2-4 gene has a single, large intron of 2,780 bp in its 5'-untranslated region, just 12 bp upstream from the ATG initiation codon of the FAD2-4 opening reading frame. A number of prospective promoter elements, including several light-responsive sequences, occur in the 5'-flanking region. The coding region of the gene is 1155 bp with no introns, and would encode a FAD2-4 polypeptide of 384 amino acids. The putative protein had four membrane-spanning helices, hallmarks of an integral membrane protein, and would probably be located in the endoplasmic reticulum. The FAD2-4 gene is indeed a functional gene, since yeast cells transformed with a plasmid containing the coding region of the gene synthesize an appreciable amount of linoleic acid (18:2), not normally made in wild-type yeast cells. The FAD2-4 gene has many structural similarities to the cotton FAD2-3 gene that was also analyzed in this laboratory.

An accurate fire model is a useful tool in predicting the behavior of a prescribed fire. Simulation of fire requires an extensive amount of data and can be accomplished best using GIS applications. This paper demonstrates integrative procedures of using of ArcGIS™, ERDAS Imagine™, GPS, and FARSITE© to predict prescribed fire behavior on the Kaibab-Paiute Reservation. ArcGIS was used to create a database incorporating all variables into a common spatial reference system and format for the FARSITE model. ArcGIS Spatial Analyst was then used to select optimal burn sites for simulation. Our predictions will be implemented in future interagency efforts towards vegetative restoration on the reservation.

When we looked at different issues in terrorism such as definitions, descriptions and motivations, groups and supporters, tactics, strategies, and victims of terrorists and terrorist activities, we see that terrorism is an issue that can occur at any time, and in any place, and it seems that the terrorism threat will still exist in the future. It is almost impossible to stop all terrorist activities all over the world, but it is possible to formulate an anti-terrorism policy that can keep terrorist activities at a minimum level and prevent planned terror activities by a well developed intelligence network. It seems that to establish a good intelligence collection system an approach in which HUMINT and TECHINT are interdependent with each other is necessary. By using a combination of human and technical intelligence collection methods, intelligence agencies can become more effective and efficient against terrorism.

The study utilized the covariance structure comparison methodology - Multigroup Analysis in Structural Equation Modeling - evaluating measurement equivalence of English and Spanish versions of an employee opinion survey. The concept of measurement equivalence was defined as consisting of four components: sample equivalence, semantic equivalence, conceptual equivalence and scalar equivalence. The results revealed that the two language versions of the survey exhibited acceptable measurement equivalence across five survey dimensions Communications, Supervision, Leadership, Job Content & Satisfaction and Company Image & Commitment. Contrary to the study second hypothesis, there was no meaningful difference in opinion scores between English-speaking and Spanish-speaking respondents on the latent construct of Job Content & Satisfaction.

The purpose of this study was to determine (a) the attentional focus strategies used by triathletes during the three stages of an Olympic distance triathlon, (b) if level of experience influences the attentional focus strategies used by triathletes, and (c) whether there is a relationship between athletes finishing times and the attentional strategies used in each stage of the race. Triathletes (N = 160) completed the Triathlon Attentional Focus Inventory, which measured association and dissociation during the swim, bike, and run. One-way ANOVAs revealed significant differences between the athletes' level of experience and the attentional strategies used, as well as differences between the athletes overall race time and the attentional strategies used during each stage of the triathlon. Athletes with more experience associated more during the race, whereas athletes with less experience dissociated more throughout the race.

A mobile ad hoc network (MANET) is a collection of mobile platforms or nodes that come together to form a network capable of communicating with each other, without the help of a central controller. To avail the maximum potential of a MANET, it is of great importance to devise a routing scheme, which will optimize upon the performance of a MANET, given the high rate of random mobility of the nodes. In a MANET individual nodes perform the routing functions like route discovery, route maintenance and delivery of packets from one node to the other. Existing routing protocols flood the network with broadcasts of route discovery messages, while attempting to establish a route. This characteristic is instrumental in deteriorating the performance of a MANET, as resource overhead triggered by broadcasts is directly proportional to the size of the network. Bounded-dynamic source routing (B-DSR), is proposed to curb this multitude of superfluous broadcasts, thus enabling to reserve valuable resources like bandwidth and battery power. B-DSR establishes a bounded region in the network, only within which, transmissions of route discovery messages are processed and validated for establishing a route. All route discovery messages reaching outside of this bounded region are dropped, thus …

With globalization and modernization, increasingly people are influenced by multiple cultures. This paper examines the case of two authors, Mark Tully and Ruskin Bond, who were born in India shortly before India's Independence (1947). Both had British parents, but one considers himself Indian while the other has retained his British identity. The focus of this paper is how and why this difference has occurred and how it has influenced their writing. Both Tully and Bond write short stories about India and Indians, particularly the small towns and villages. Their reasons for writing, however, are very different. Tully writes to achieve social change, while Bond writes because he loves to write.

The widely used vector model maintains its popularity because of its simplicity, fast speed, and the appeal of using spatial proximity for semantic proximity. However, this model faces a disadvantage that is associated with the vagueness from keywords overlapping. Efforts have been made to improve the vector model. The research on improving document representation has been focused on four areas, namely, statistical co-occurrence of related items, forming term phrases, grouping of related words, and representing the content of documents. In this thesis, we propose the idea-indexing model to improve document representation for the filtering task in IR. The idea-indexing model matches document terms with the ideas they express and indexes the document with these ideas. This indexing scheme represents the document with its semantics instead of sets of independent terms. We show in this thesis that indexing with ideas leads to better performance.

The primary goal of this thesis is to provide a comparative analysis of the institutional and organizational mechanisms designed to monitor and control political corruption at the national level. The paper will provide comparisons of these arraignments and control systems across three nations. The thesis will identify differences across countries in terms of organizational and institutional political corruption control mechanisms, and use the CPI index to suggest and identify those control mechanisms that appear to be present in nations with low CPI measurements. Finally, the thesis will conclude with the discussion concerning the future prospects for controlling political corruption in Turkey based on the comparative analysis described above.

My thesis focuses on philosophical themes implicit in corridor conservation, using the Big Thicket National Preserve as an example. The way in which corridors, boundaries and communities are ambiguous, as both limits and connections, is dealt with. Corridor-patch matrices assemble ecological and human groups into temporary communities, often with conflicting interests. Such constellations foreground how a foreigner's boundary crossing is a notion important to both conservation and a philosophical study of being, seen as being always in relation with otherness. In this context, the notion of foreignness and Jean-Luc Nancy's idea of being-with is explored. Understanding the complex network of relations in which an entity exists leads to an awareness of its ambiguous nature. To facilitate judgment with such ambiguity, one needs a contextual understanding of a situation.

The proposed study examined differences in self-concept between ADHD (n = 61) and non-ADHD boys and girls. Participants included 108 children between 6 and 11 years old. Children completed the Self Description Questionnaire-I, and teacher reports of child competence were obtained. Girls reported lower physical ability and mathematics self-concept than boys. The results also indicated that ADHD girls may be more susceptible to low physical ability and mathematics self-concept than control children or ADHD boys. Teachers also rated ADHD girls as having lower scholastic competence than the other three groups. Teachers reported significant differences in level of competence based on ADHD status. The implications of the current study and directions for future research will be presented.

Three different types of cage crown ethers have been prepared and their complexation properties with Ag(I) have been studied. Atomic absorption, fluorescence quenching, and UV absorption have been used to study the interaction between the hosts (cage crown ethers) and guests (Ag+). For the cage-annulated crown ethers that contain aromatic rings, cation-π and π-π interactions may contribute significantly to the overall complexation ability of the host system. Piperazine groups may cooperate, and the piperazine nitrogen atoms provide unshared electrons, which may form a complex with Ag+. In addition, relatively soft donor atoms (e.g., Br) are well-suited for complexation with Ag+, which is a softer Lewis acid than alkali metal cations.

Critics and audiences alike have neglected the idea of Wilde as a precursor to Beckett. But I contend that a closer look at each writer's aesthetic and philosophic tendencies-for instance, their interest in the fluid nature of self, their understanding of identity as a performance, and their belief in language as both a way in and a way out of stagnancy -will connect them in surprising and highly significant ways. This thesis will focus on the ways in which Wilde prefigures Beckett as a dramatist. Indeed, many of the themes that Beckett, free from the constraints of a censor and from the societal restrictions of Victorian England, unabashedly details in his drama are to be found residing obscurely in Wilde. Understanding Beckett's major dramatic themes and motifs therefore yields new strategies for reading Wilde.

Over the last decade there has been a rapid development of United States quick service restaurant companies such as KFC and McDonalds in China. Increasingly urban Chinese consumers patronize these restaurants as a way to experience American culture. For some it is becoming a part of their eating pattern. Recent health studies have demonstrated that nutritional diseases are increasing in China. This study accessed urban Chinese consumers' perceptions about U.S. quick service restaurants and their knowledge about the nutritional value that U.S. quick service food can provide. This study revealed that Chinese consumers' perceptions and knowledge about U.S. quick service impacts their patronage. Additionally, the study determined correlation between consumer patronage and reported health status as well as consumers' length of patronage negative influence on their health status. The results of this study will help U.S. quick service restaurants in educating consumers on nutrition and improving the menus.

Topic Detection and Tracking (TDT) research has produced some successful statistical tracking systems. While lexical chaining, a non-statistical approach, has also been applied to the task of tracking by Carthy and Stokes for the 2001 TDT evaluation, an efficient tracking system based on this technology has yet to be developed. In thesis we investigate two new techniques which can improve Carthy's original design. First, at the core of our system is a semantic domain chainer. This chainer relies not only on the WordNet database for semantic relationships but also on Magnini's semantic domain database, which is an extension of WordNet. The domain-chaining algorithm is a linear algorithm. Second, to handle proper nouns, we gather all of the ones that occur in a news story together in a chain reserved for proper nouns. In this thesis we also discuss the linguistic limitations of lexical chainers to represent textual meaning.

The thesis examines the relationship between Martha Stewart's rendition of domesticity and a broader cultural trend of the late 1990s U.S. domestic retreatism. It argues that the mode of construction and representation of the "domestic dream" in Stewart's programs cannot be examined outside of such concepts as class and ethnicity, whose understanding depends on the cultural, social, and political context of a given era, a context, in which they become transparent as aspects of the Western (white, patriarchal) status quo. Performing a deconstructive reading of these categories as employed by Stewart in the process of creation of her media persona, the thesis examines what the negative as well as positive reactions to "Martha Stewart" convey about the condition of American society of the late 1990s and early 2000s.

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.

Laboratory single-species toxicity tests are used to assess the effects of contaminants on aquatic biota. Questions remain as to how accurately these controlled toxicity tests predict sitespecific bioavailability and effects of metals. Concurrent 42-day Hyalella azteca exposures were performed with cadmium and final treated municipal effluent in the laboratory and at the University of North Texas Stream Research Facility. Further laboratory testing in reconstituted hard water was also conducted. Endpoints evaluated include survival, growth, reproduction, and Cd body burden. My results demonstrate that laboratory toxicity tests may overestimate toxicity responses to cadmium when compared to effluent dominated stream exposures. Discrepancies between endpoints in the three tests likely resulted from increased food sources and decreased cadmium bioavailability in stream mesocosms

By examining southwestern masculinity from three separate lenses of cultural experience, Mexican American, Native American and female, this thesis aims to acknowledge the blending of masculinities that is taking place in both the fictitious and factual southwest. Long gone are the days when the cowboys chased down the savage Indians or the Mexican bandits. Southwestern literature now focuses on how these different cultures and traditions can re-construct their masculinities in a way that will be beneficial to all. The southwest is a land of borders and liminal spaces between the United States and Mexico, between brown and white, legal and illegal. All of these borders converge here to create the last American frontier. These converging borders also encompass converging traditions, cultures, and genders. By blending the cowboy, the macho, and the warrior, perhaps these Southwestern writers can construct a liminal masculinity more representative of the southwest itself.

Effective stewardship of forest ecosystems make it imperative to measure, monitor, and predict the dynamic changes of forest ecology. Measuring and monitoring provides us a picture of a forest's current state and the necessary data to formulate models for prediction. However, societal and natural events alter the course of a forest's development. A simulation environment that takes into account these events will facilitate forest management. In this thesis, we describe an efficient parallel implementation of a land cover use model, Mosaic, and discuss the development efforts to incorporate spatial interaction and succession dynamics into the model. To evaluate the performance of our implementation, an extensive set of simulation experiments was carried out using a dataset representing the H.J. Andrews Forest in the Oregon Cascades. Results indicate that a significant reduction in the simulation execution time of our parallel model can be achieved as compared to uni-processor simulations.

Definition of privacy has changed by the changes and improvements in information and surveillance technologies. These changes and improvement need new legal decisions for new kinds of privacy invasions. This study explores the scope of privacy right, particularly when a technological surveillance has occurred by law enforcement agencies. It focuses in particular on increasing law enforcements' surveillance technologies and devices that have the potential to impact citizens' information privacy. These increasing changes in surveillance technologies have important implications both for law enforcements and citizens. This study also discusses increasing law enforcement surveillance for the public's security, changes of the laws that allow law enforcements to use new surveillance powers as a war on terrorism, and the citizens concerns of information privacy. A particular attention is given to the recent public opinion surveys which show citizens' increasing privacy concerns. Finally, a set of recommendations to figure out security-privacy debate and reduce the privacy concerns of the citizens is offered.

No Way Out: A Historical Documentary is the written companion to a forty-minute documentary film entitled "No Way Out". The film deals with a 1974 inmate standoff at a prison in Huntsville, Texas known as the Carrasco Incident. The film examines the prison takeover through the eyes of those who lived through it. Composed of five interviews, "No Way Out" is a compilation of various points of view ranging from former hostages, members of the press, and law enforcement. The written companion for this piece discusses the three phases of the production for this film. These chapters are designed to share with the reader the various intricacies of documentary filmmaking. The thesis also explores theoretical issues concerning collective memory, coping behavior, and the ethics of historical documentary filmmaking.

The focus of my work is the incorporation of three-dimensional sculptural forms into the design of my garments while still maintaining the functional purpose of the garment. Origami paper folding is the inspiration for the sculptural forms. The major endeavor was to explore and solve the relationship between the organic human forms and the geometric forms created by the origami paper folds. This presented a challenge of exact precision. During this process, I experimented with different fabrics, which can accommodate the sharp creases and retain the shape. A variety of folding patterns were also explored. Although the design should be innovative and creative, the final garment must be wearable and comfortable.

This thesis is an examination of "paranoid conspiracy" films, a film noir subgenre that emerged in mainstream American cinema in the early 1970s and turns on vast, shadowy conspiracies located within U.S. "power structures" (government agencies, the military, the media) and directed against the American public. Specifically, it focuses on the emergence of these films in the 1970s, their almost complete disappearance during the Reagan presidency, and subsequent reemergence in the early 1990s. Placing representative texts in the context of U.S. political and social reality of the last three decades, it analyzes the relationship between the conspiracy theory genre, the "crisis of confidence" in the American society, and the process of formation of American national identity.
