This project utilizes a case study approach to explore the various ways in which the portrayals of gay people have changed on American television. Three contemporary programs - Will & Grace, Queer Eye for the Straight Guy and The L Word - are examined as examples of how far American television has progressed in terms of treating gay people with respect. Whether those shows move beyond merely presenting gay characters and into a level of actively challenging mainstream views on gay people is also examined. Findings suggest different factors affect the ability of the individual programs to test said views - including the genres to which each belongs, and their presence on network television (Will & Grace), basic cable (Queer Eye for the Straight Guy) or premium cable (The L Word). While all three programs show some tendencies toward queerness, they also take steps toward negotiating with mainstream culture, indicating that complete queerness may be an unattainable goal on American television.

Few studies have systematically evaluated whether preferences can reliably be identified using brief procedures. Typically, studies have used brief procedures to select potential reinforcers for use in intervention procedures. A total of 17 food and leisure paired-choice preference assessments were administered to 10 subjects in order to evaluate the extent to which the results of a brief (i.e., single-session) assessment correspond with those from more extended procedures (i.e., 5 sessions). Eleven out of the 17 brief and extended assessments identified the same stimulus as the most preferred (highest rank). Outcomes suggest that a brief assessment can be useful when a single, potent reinforcing stimulus is desired, and an extended assessment should be conducted when a larger number of preferred stimuli is desired.

Pigeons were trained on a zero-delay identity match-to-sample task. Experiment 1 started with every correct match reinforced with grain access and subsequent conditions include higher fixed-ratio values. Experiment 2 included the same fixed-ratio values as experiment 1 with and without a limited hold (LH) on the opportunity to select a comparison stimulus. Prior research suggested that trials after reinforcement would have an increased likelihood of error, and that these errors would be reduced in LH conditions. Results confirmed this expected error pattern and in most LH conditions errors were reduced early in the ratio.

Banach's contraction principle is probably one of the most important theorems in fixed point theory. It has been used to develop much of the rest of fixed point theory. Another key result in the field is a theorem due to Browder, Göhde, and Kirk involving Hilbert spaces and nonexpansive mappings. Several applications of Banach's contraction principle are made. Some of these applications involve obtaining new metrics on a space, forcing a continuous map to have a fixed point, and using conditions on the boundary of a closed ball in a Banach space to obtain a fixed point. Finally, a development of the theorem due to Browder et al. is given with Hilbert spaces replaced by uniformly convex Banach spaces.

Natural language is inherently ambiguous. For example, the word "bank" can mean a financial institution or a river shore. Finding the correct meaning of a word in a particular context is a task known as word sense disambiguation (WSD), which is essential for many natural language processing applications such as machine translation, information retrieval, and others. While most current WSD methods try to disambiguate a small number of words for which enough annotated examples are available, the method proposed in this thesis attempts to address all words in unrestricted text. The method is based on constraints imposed by syntactic dependencies and concept generalizations drawn from an external dictionary. The method was tested on standard benchmarks as used during the SENSEVAL-2 and SENSEVAL-3 WSD international evaluation exercises, and was found to be competitive.

This thesis project explores Chicana feminist Gloria Anzaldúa's notion of a new mestiza consciousness, in which the marginalized ethnic American woman transcends her Otherness, breaks down the borders between her different identities, and creates a Thirdspace. Through the rehearsal and performance process, three ethnic American women employed Robert Scholes' model of textuality-the consumption and production of texts-as a framework to construct a new mestiza consciousness, and create a Thirdspace. The project set to determine what strategies were significant rehearsal techniques for encouraging the cast members to exercise textual power and claim a new mestiza identity, a Thirdspace. The results reveal four overarching factors involved in assuming textual power through rehearsal and performance in the production-building trust, having appropriate skills, assuming ownership and responsibility, and overcoming performance anxiety. The discussion addresses the direct link between Thirdspace and Scholes' notion of production of original texts.

Private property in the United States arose out of a tradition that emphasized the individual freedom to control holdings without interference from governmental influences. A sharp distinction between society as a whole and individual rights isolated ownership of private property from a notion of the common good. This dualistic framework excludes the possibility for forms of property that do not fall completely into either category. Property ownership attitudes are central to issues that often divide environmentalists and landowners. Property rights must be put in the context to understand the divergence between landowner attitudes and provisions made when the institution of private property was created. Finally, land itself as a type of property should be considered ethically distinct from other forms of property because of the interdependencies of human and nonhuman interests that the science of ecology has revealed.

The present study examined the perceptions of teams and managers on team potency levels as a function of stage of team development. Drawing from the power and influence literature, potency was established as a means by which to assess team's internal dynamics. Stage of team development was separated into four categories including pseudo, potential, real and high performance teams. Archival data included 45 teams and managers gathered from the manufacturing and service industries. Results indicated a significant linear relationship between team perceptions of team potency and stage of team development. Additionally, potency perceptions of teams significantly differentiated between the four stages of team development. Manager perceptions of team potency produced non-significant results. Possible explanations of the results as well as implications for practice and future research are provided.

The design of autonomous agents capable of performing a given goal in a 3D domain continues to be a challenge for computer animated story generation systems. We present a novel prototype which consists of a 3D engine and a planner for a simple virtual world. We incorporate the 2D planner into the 3D engine to provide 3D animations. Based on the plan, the 3D world is created and the objects are positioned. Then the plan is linearized into simpler actions for object animation and rendered via the 3D engine. We use JINNI3D as the engine and WARPLAN-C as the planner for the above-mentioned prototype. The user can interact with the system using a simple natural language interface. The interface consists of a shallow parser, which is capable of identifying a set of predefined basic commands. The command given by the user is considered as the goal for the planner. The resulting plan is created and rendered in 3D. The overall system is comparable to a character based interactive story generation system except that it is limited to the predefined 3D environment.

As Yancey (2003) has pointed out, the intentional character of racially integrated churches tends to lessen the social distance between Whites and minorities. The purpose of this study is to examine how racially hierarchy-attenuating and hierarchy-enhancing environments affect classism and sexism attitudes among congregations. The finding shows that multiracial churches promote H-A environment for class and race diversity, but not for gender equality. The class and race diversity is affected by organizational structure; on the other hand, gender equality is influenced by theologies. This study finds the answers to this discrepancy from the effect of biblical teachings on classist and sexist attitudes and the cumulative effect of structured domination of women.

This study attempts to explain why some countries experience multiple civil wars while others who have experienced a civil war build long-term stability from the rubble of conflict. The explanation of why civil war recurs focuses on the collective action problem, centering on the rebel leaders' ability to solve the Rebel's Dilemma. I further argue that once the Rebel's Dilemma has been solved once it is much easier for rebel leaders to solve it again and again. The empirical finds suggest that the political situation resulting from the first war plays a strong role in the solutions to the collective action problem and thus the long-term stability following a civil war. Namely, the level of democracy, partition and third party enforcement of the peace all affect the ability of the rebel leaders to solve the collective action problem and the likelihood of another civil war.

This thesis film is an overview of Nazi Germany, primarily told through the use of their own propaganda images, and structured in such a way as to make the viewer question what they think they know about the past, present, and future. This paper is a discussion of the process that went into making the film and some of the ideas connected to it that could not be brought out in the documentary.

This study is a test of a methodology to predict changes in elevation and shoreline position of coastal wetlands in Trinity Bay, Texas, in response to projected sea level rise. The study combines numerical modeling and a geographic information system. A smoothing technique is used on a United States Geographical Survey (USGS) digital elevation model to obtain elevation profiles that more accurately represent the gently sloping wetlands surface. The numerical model estimates the expected elevation change by raster cell based on input parameters of predicted sea level rise, mineral and organic sedimentation rates, and sediment autocompaction rates. A GIS is used to display predicted elevation changes and changes in shoreline position as a result of four projected sea level rise scenarios over the next 100 years. Results demonstrate that this numerical model and methodology are promising as a technique of modeling predicted elevation change and shoreline migration in wetlands. The approach has potential utility in coastal management applications.

One area of history that historians have ignored is that of children and their relationship to witchcraft and the witch trials. This thesis begins with a survey of historical done on the general theme of childhood, and moves on to review secondary literature about children and the continental witch trials. The thesis also reviews demonological theory relating to children and the roles children played in the minds of continental and English demonologists. Children played various roles: murder victims, victims of dedication to Satan, child-witches, witnesses for the prosecution, victims of bewitchment or possession, and victims of seduction into witchcraft. The final section of the thesis deals with children and English witchcraft. In England children tended to play the same roles as described by the demonologists.

Wine & Beer tells the story of childhood friends Brian and Vic who, after spending some time apart, deal with the tensions of sexual orientation after they attempt to renew their friendship. At the beginning it seems that Vic's sexuality will not be a problem, but after the two friends hang out in a local bar, Brian realizes his hometown is not as tolerant as he is. The couple is faced with family and social concerns, which goes from the argumentative to the violent. As the main characters try to mingle with the conservative town, they soon find themselves looked upon by a small town resistant to change. This 35-minute film explores homophobia and violence in small town USA.

Grounded in the social constructivism tradition, this study examined the role of communication in the glocalization and acculturation of HIV/AIDS by a section of sexually active Ugandans then living in Rakai district during the advent of the epidemic in 1982. Sixty-four women and men participated in ten focus group discussions in Rakai and Kampala districts. Five themes emerged from the data highlighting how individuals and communities made sense of the epidemic, the omnipresence of death, how they understood the HIV/AIDS campaign, and how they are currently coping with its backlash. The study concludes that HIV/AIDS is socially constructed and can be understood better from local perspectives rather than from a globalized view. The study emphasizes the integration of cultural idiosyncrasies in any health communication campaigns to realize behavioral change.

A study of the life history and ecology of Camelobaetidius variabilis was conducted in Honey Creek, OK from February 2003-April 2004. Nymph development was assessed using changes in external morphology. Laboratory reared nymphs were used to calculate number of degree days to complete development (772 degree days at 20.8° C ±.38° C), which was used to determine voltinism. Field collected nymph microhabitat distribution was used in assessing microhabitat distribution. Nymphal thermoregulation was assessed during the winter and spring by comparing nymphal numbers present in shaded and un-shaded habitats. Camelobaetidius variabilis nymphs showed preference for algal microhabitats during the spring and leaf packs in the winter. Nymphs inhabited leaf packs to increase metabolic rate during the winter. Increased temperatures aid in development of nymphs. Camelobaetidius variabilis exhibited a multivoltine life cycle with six overlapping generations.

Forsythia is a collection of poetry that examines the transformative power of observation.

User modeling enables in the computation of the traffic density in a cellular network, which can be used to optimize the placement of base stations and radio network controllers as well as to analyze the performance of resource management algorithms towards meeting the final goal: the calculation and maximization of network capacity and throughput for different data rate services. An analytical model is presented for approximating the user distributions in multi-cell third generation wideband code division multiple access (WCDMA) networks using 2-dimensional Gaussian distributions by determining the means and the standard deviations of the distributions for every cell. This model allows for the calculation of the inter-cell interference and the reverse-link capacity of the network. An analytical model for optimizing capacity in multi-cell WCDMA networks is presented. Capacity is optimized for different spreading factors and for perfect and imperfect power control. Numerical results show that the SIR threshold for the received signals is decreased by 0.5 to 1.5 dB due to the imperfect power control. The results also show that the determined parameters of the 2-dimensional Gaussian model match well with traditional methods for modeling user distribution. A call admission control algorithm is designed that maximizes the throughput in multi-cell …

Treatment of 4,5 bis-(diphenylphosphino)-cyclopenten-1,3 dione with thiophene carboxyaldehyde in dichloromethane, in the presence of molecular sieves results in a new heterocyclic compound, 2-(2-thienylidene)-4,5-bis(diphenylphosphino)-4-cyclopenten-1,3-dione (ligand), with a high yield. This product was characterized by using both IR and NMR spectroscopic techniques and the solid-state structure of the ligand was determined using X-ray crystallography. When the ligand was treated with the solvent stabilized intermediate of ReBr(CO)5 with THF, a monomeric metal complex, fac-BrRe(CO)3[2-(2-thienylidene)-4,5-bis(diphenylphosphino)-4-cyclopenten-1,3-dione] was the result. The solid-state structure of the monomeric metal complex was determined using X-ray crystallography. Photolysis and thermolysis studies of the complex will be further explored.

Most studies of the Mass in B Minor deal with the history of the work, its reception history, primary sources, performance practice issues, rhetoric, and even theological and numerical symbolism. However, little research focuses on an in-depth analysis of the music itself. Of the few analytical studies undertaken, to date only a limited number attempt to explain Bach's use of parody technique or unity in the whole composition. This thesis focuses on understanding three primary concerns in regards to the Mass in B minor: to comprehend how preexistent material was adapted to the context of the Mass, how this material functions in the network of the entire composition, and how unity is achieved by means of large-scale voice leading. The results of this study not only provide new information about this monument of Western music, but also provide insight to the deep sense of large-scale structure in Bach's work.

Texas is the last remaining state to utilize the rule of capture, a doctrine based on English Common Law, as a means of regulating groundwater resources. Many of the western states originally used the rule of capture to regulate their groundwater resources, but over time, each of these states replaced the rule of capture with other groundwater laws and regulations. The Texas Water Development Board (TWDB) State Water Plan, Water for Texas-2002, warned Texans if current water usage and laws do not change, there will be an unmet need of 7.5 million acre-feet of water annually by 2050. This caused individuals in state and local government to begin asking the question, "How are we going to meet our future water needs?" In the search for a solution to the water shortage problem people have divided themselves into two groups: one wants to consider the implementation of water conservation measures to reduce per capita water use in order to meet future demands; while the other group wants to spend millions of dollars to build reservoirs and dams along with laying thousands of miles of pipeline to move water around the state. The fact that Texas has yet to come up with …

Longitudinal methods have become an improved and essential means of measuring intra-individual change over time. Yet one of the greatest and most hazardous drawbacks studying participants over multiple sessions can be the loss of participants over time. This study attempts to illuminate the problem of attrition in longitudinal research by estimating the mean effect sizes for participant loss across 57 studies published in 13 prestigious journals which regularly use older participants. Results estimate overall attrition to be around 34% of the original sample. The subsequent break down of attrition into its subtypes yield mean effect sizes for attrition due to Refusal (8%), Loss of contact (10%), Illness (6%), and Death (14%) in studies sampling from adults 50 years or older. Analyses were then conducted via meta-analytic one-way ANOVA and weighted regression to identify possible moderators of overall attrition and their four subtypes.

Hydrologic models were used to examine the effects of land cover change on the flow regime of a watershed located in North-Central Texas. Additionally, the effect of spatial resolution was examined by conducting the simulations using sub-watersheds of different sizes to account for the watershed. Using the Army Corps of Engineers, Hydrologic Engineering Center Hydrologic Modeling System (HEC-HMS), two different modeling methods were evaluated at the different sub-watershed resolutions for four rainfall events. Calibration results indicate using the smaller spatial resolutions improves the model results. Different scenarios for land cover change were evaluated for all resolutions using both models. As land cover change increased, the amount of flow from the watershed increased.
