Behavioral economic theory describes a relation between response requirement and magnitude of reinforcement, and combines these variables into one independent variable (unit price) affecting operant behavior. This study investigated the relative effects of cumulative feedback on consumption for money as a commodity. Subjects were exposed to ranges of unit prices with or without a cumulative feedback bar on the computer screen indicating monetary earnings. For all participants in this study, consumption of money was a decreasing function of unit prices and the results from the present study are consistent with the behavioral economic prediction that increasing the unit price of a commodity will decrease consumption of that commodity. Analyses of demand curves, elasticity coefficients and response rates suggested differences between Feedback and No Feedback groups, although these were small and not statistically significant. The small differences observed were consistent with a behavior strengthening effect of feedback.

The impact of training on virtual team effectiveness was assessed in five areas: communication, planning tasks and setting goals, solving problems and making decisions, resolving conflict, and responding to customer requirements. A 12-page survey was developed exploring all aspects of virtual teams. 180 surveys were distributed, 52 were returned representing 43 companies. Training led to higher effectiveness in planning tasks and setting goals, solving problems and making decisions, and conflict resolution, but not in communication and responding to customer requirements. Training may not solve all the problems that virtual teams will encounter; however, training will make the challenges easier to handle.

Present Absence is a work that integrates electronic processing and live performance. It is approximately 20 minutes long and is divided into three movements. The movements are distinct from each other, but are related through various elements. Incorporating electronic processing and live performance can be cumbersome. The primary objective of this piece is to use electronic processing in a manner that liberates the performers from any restrictions imposed by the use of electronic processing. The electronic processing in the work is accomplished through the program MAX/Msp, a real-time digital signal processing environment. The patch that was created for this piece is called MOO-V. This paper discusses the both the technical details in the construction of this patch, and the aesthetic it serves.

Because media influence public opinion, it is often surmised that media also influence the decisions of police executives. This exploratory case study examined the relationship between police and media during the Oklahoma City bombing investigation and subsequent trials of Timothy McVeigh and Terry Nichols. Findings indicate that media influence police executive decisions when police and media interact closely. It was found that during the Oklahoma City bombing investigation and trials, police on the outer perimeter were influenced most and police conducting the investigation or who were tasked to court room security were influenced the least. It was concluded, based on the consensus of respondents interviewed, that media do influence police executive decisions.

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.

Understanding the relation between personality characteristics, psychopathology, and sexual offenses can contribute to developing more effective treatment interventions. Previous research with sex offenders has focused on general personality traits or inconsistently classified sex offenders based on psychopathology. It was hypothesized that combining personality and psychopathological traits can assist in understanding sex offenders. The current study evaluated 88 male sex offenders in a court-mandated outpatient treatment program utilizing the NEO-PI-R and the MMPI-2. Three clusters of child molesters were examined for differences in personality characteristics and number of offenses. A second-order principle axis factor (PAF) analysis of personality and psychopathology traits revealed three factors: Psychological Distress, Excitement-Seeking, and Social Desirability. The potential clinical utility of these dimensions in predicting treatment compliance is examined.

Methods for the determining the functional properties of problem behaviors are necessary for the design of successful treatments. Many of the currently utilized methodologies are chosen based on their speed, ease of application or for the perceived risk-reduction they afford. However, when thoroughly analyzed many of these methods fall short of their intended purpose. The current study attempted to assess dangerous problem behavior through a functional assessment of functionally related precursor behaviors during analog sessions. Results indicate that for three participants, placing the reinforcing contingencies on these related precursor behaviors produced differentiated outcomes during the assessment. These outcomes matched the outcomes of assessments of the more dangerous problem behaviors.

This study examines two of the smaller American choral societies that together existed for just over 30 years, 1888 to 1919: The Gounod and New Haven Oratorio Societies of New Haven, Connecticut. These societies are important because, especially in the case of the New Haven Society, they were closely related to Yale University and the work of Horatio Parker. One must assume from the onset that the two choral groups examined in the following pages did not have the prominence of the many larger New England choral societies. However a more detailed knowledge about the struggles, successes, influence and leadership of two smaller societies illuminates a field of research in the history of American choral music that has been largely ignored.

The oboe, which first came into being in the middle of the seventeenth century in France, underwent a number of changes throughout the following century. French instruments were influenced both by local practices and by the introduction of influences from other parts of Europe. The background of the makers of these instruments as well as the physical properties of the oboes help to illuminate the development of the instrument during this period. The examination of measurements, technical drawings, photographs, and biographical data clarify the development and dissemination of practices in oboe building throughout eighteenth-century France. This clarification provides new insight into a critical period of oboe development which has hitherto not been exclusively addressed.

Throughout the recorded history of vocal development certain characteristics can be traced to nationalistic roots. This work explores the four major schools of singing: English, French, German and Italian and includes a brief history of the pedagogical development and ideas of these schools' development. In addition, specific techniques and their similarities and differences, between each school is explored. Through the use of students as a control group, various characteristics within the four schools are implemented in coaching. The results are noted. The major theme of this work is to outline the major schools of vocal pedagogy and to contrast and compare specific techniques found in each school. Furthermore, regarding the individual student, the positive and negative effects of teaching in a dedicated fashion to one school versus the implementation of proven methods, of various schools, even though they cross nationalistic boundaries, has been the major thrust of this investigation

The relationship between fathers' and mothers' gender-role ideas and fathers' level of participation in general housework has been well documented. Data from a study in 1998 were used to explore specific aspects of this relationship. In particular, fathers' and mothers' genderrole ideas with regard to childcare (childcare ideas) was examined to see whether these ideas influence paternal childcare participation. Specifically, what impact they had on performance of childcare tasks and the time fathers spent with their children. The responses of 38 couples (76 individuals) were analyzed. No statistically significant relationships were found between the variables. The distribution of the data suggests that even though most fathers claimed to have nontraditional childcare ideas, most mothers still performed the great majority of childcare tasks.

There were two purposes of the current study: (1) to evaluate if the East Asian Student Stress Inventory could be used to assess the stress experienced by International and American students at the University of North Texas and (2) to determine if the Inventory could discriminate between the two groups on the basis of the stress assessment. A sample of International (n=205) and American (n=216) graduate and undergraduate students completed the inventory. Results indicated that the EASSI could be generalized to a wider spectrum of International students. Using principal component factor analysis with varimax rotation, eight factors were extracted: culture shock, physiological symptoms, family pressure, test anxiety, financial difficulties, attitude toward study, social support and academic self esteem. The inventory clearly discriminated between the two groups on the subscales of culture shock, family pressure and attitude toward study and the International students scored higher on these subscales.

During World War II, the Army Air Force waged three strategic air offensives in and from China against Japan. At first, the Flying Tigers and 10th Air Force constituted the whole of American aid to China, but the effort soon expanded. Supported by Chiang Kai-shek, Claire Chennault and his 14th Air Force waged an anti-shipping campaign, to which the Japanese Imperial Army responded with Operation Ichigo and against which Joseph Stilwell accurately warned. 20th Bomber Command used B-29s to wage Operation Matterhorn, failed, and later conducted PACAID missions. 14th Air Force then waged a counterproductive transportation campaign as The Pacific War, also known as the Greater East Asian War, ended. Events in the China-Burma-India and China Theaters provide lessons in logistics, targeting, training, and air-ground cooperation that are applicable in the post-Cold War era.

The purpose of this study was to examine the suitability of the YSI model 6600 Environmental Monitoring System (multiprobe) for long term deployment at a site in Lewisville Lake, Texas. Specifically, agreement between a laboratory extraction procedure and the multiprobe chlorophyll/fluorescence readings was examined. Preliminary studies involved determining the best method for disrupting algal cells prior to analysis and examining the precision and linearity of the acetone extraction procedure. Cell disruption by mortar and pestle grinding was preferable to bath sonication. Comparison of the chlorophyll/fluorescence readings from the multiprobe and the extraction procedure indicated that they were significantly correlated but temperature dependent.

This thesis examines the history of the Greater Dallas Crime Commission and its effectiveness within the criminal justice system. It is a private agency established fifty (50) years ago to monitor and investigate the criminal justice system. Today, it serves as a source of funding for criminal justice agencies, provides awards and recognition forums for law enforcement and lobbies for legal revisions of the criminal code. The research is designed to examine their role within the criminal justice system. Whether current crime theories are supported by the commission is central to the thesis. There are no prior studies available of crime commissions perhaps because they are privately funded and operated by civilians. Crime commissions do exert influence, politically and financially, upon law enforcement. It is reflected often in their history. The extent of this effect is the subject of the paper. To this end, the commission's role in changing state laws, providing funds for police training, recognizing prosecutors and paying awards to informants lends credibility to their role in the criminal justice system. Their function has often changed during the fifty-year history. If there is a deficit, it may be that the commission has the capability, through its sphere of …

The illustrative work of Edward Linley Sambourne for Punch magazine during the period 1901-1910 addresses a myriad of political topics prevalent during the Edwardian period in British history. This thesis examines two of those topics - Women's Suffrage and Socialism - through their artistic treatment by one of Britain's most influential periodicals. Through a study of the historical context and iconography of selected cartoons-of-the-week, one is better equipped to understand and appreciate the meaning, message, and humor in the cartoons. Chapter 1 introduces the Sambourne, Punch magazine, and the Edwardian period in general. Chapters 2 and 3 discuss four Women's Suffrage cartoons and four Socialism cartoons respectively. Chapter 4 draws conclusions regarding Sambourne's techniques as a cartoonist as well as the relationship between the text and image in his illustrations.

The hypothesis that language discrimination contributes to protest and/or rebellion is tested. Constitutional language policy regarding administrative/judicial, educational and other matters is measured on three separate scales developed for this study; the status of each minority group's language under its country's policy is measured by another set of scales. Protest and rebellion variables are taken from Gurr's Minorities at Risk study. Findings include an indication that group language status contributes positively to protest and rebellion until a language attains moderate recognition by the government, at which point status develops a negative relationship with protest and rebellion, and an indication that countries with wider internal variations in their treatment of language groups experience higher levels of protest and rebellion on the part of minority groups.

There were two primary goals in this investigation. The first goal was to determine if results from field tests (time-trials and a Conconi incremental test) are related to performance in mass-start long-distance bicycle races. The second goal was to investigate inter-relationships among field test variables. The testing variables measured were critical velocity (CV), Conconi anaerobic threshold (AT) velocity, 4mM AT velocity, fatigue index, peak blood lactate, and anaerobic work capacity. Participants were USCF 30 category 1 through 5 cyclists. Participants performed one 20.75 km and two 10.37 km all-out tests in the field. They also performed an incremental test. The tests were performed at one-week intervals. Results from the field tests were compared to recent mass-start racing performance. Results indicated that Conconi AT velocity was related to performance in a 161-km race. There was also a relationship between 4mM AT velocity and CV and between Conconi AT velocity and 4mM AT velocity. It was concluded that field tests might provide information about performance ability in mass-start long-distance bicycle races.

This thesis studies the style of Native American portrait photographs of William S. Soule (1836-1908), John K. Hillers (1834-1925), and William E. Irwin (1871-1935), who worked in Oklahoma from 1869 to 1904. The examination of the three men's work revealed that each artist had different motivations for creating Native American portrait photographs, and a result, used a distinct style. However, despite the individual artistic styles, each artist conformed to Native American stereotypes common during the nineteenth-century. The thesis includes a discussion of the history of the area, photographer biographies, a stylistic analysis of the photographs, and how the images fit into American Indian stereotypes.

The Industrial Laser is firmly established in metalcutting as the tool of choice for many applications. The elevator division of Montgomery KONE Inc., in an effort to move towards quality, ontime, complete deliveries and 100% customer satisfaction, decided to invest in new equipment to improve manufacturing processes. A huge investment is proposed for a laser-cutting machine. It is the responsibility of Manufacturing Engineering to direct the management by justifying its benefits, which includes payback time and financial gains. Factors such as common line cutting, automated material handling system and cutting time were involved in justification of the initial cost of a laser-cutting machine. Comparative statistics on appropriate factors accurately determine and justify the initial cost of a laser-cutting machine.

Assessment of aquatic plant selection by waterfowl has been conducted during the winters of 1997-2000 on 49 0.2-0.79 ha research ponds in north central Texas. Ponds were categorized by dominant plant species into eight habitat types. Census with waterfowl species identification were performed to investigate impacts of aquatic vegetation and water depth on waterfowl. Eighteen waterfowl species were observed. Peak migration occurred in late December/early January. Mixed native ponds and mixed native/hydrilla ponds were the most frequently selected habitat types. The study included correlation analysis between pond water levels and waterfowl use. Full ponds received greatest use followed by half full ponds, while almost empty ponds received minimal use. Time activity budgets were conducted on waterfowl utilizing mixed native and hydrilla ponds to compare waterfowl time partitioning on native aquatic vegetation versus hydrilla. Although only minor differences were found in time budgets, social status appears to be strongly related to habitat selection. Ducks on native ponds were paired (86%), conversely no ducks on hydrilla ponds were paired. Hydrilla pond although frequently utilized, were populated by lower status birds mostly single hens.

Portrait of Your Stream (POYS) is a stream ecology and student action program designed for use with middle-school students. The program is correlated with learning cycle pedagogical methods emphasizing student-centered lessons and activities in both classroom and outdoor settings. Implementation of a pilot program in the Fall semester of 1999 was used to collect formal and informal responses and data from students and teachers. Data included changes in student knowledge, skills and attitudes and were analyzed for determination of the success of program objectives and modifications to the program. The final POYS program is currently distributed and administered by the Botanical Research Institute of Texas.

This study began testing the Sewell and Williams (in press) model that differing trauma types yield differing presentations in social versus event processing domains. Other hypotheses explored trauma type with levels of guilt, and shame-proneness with anxiety. Volunteers were 44 male combat veterans being treated for PTSD. Data analyses determined whether trauma type related to guilt and perceived social support and whether shame-proneness related to levels of anxiety. High shame persons may process anxiety and social support differently than low shame persons. Results can assist professionals understand how a person's functioning is affected by certain types of trauma. Future research should focus on increasing social support for persons who have experienced trauma.

This study investigates the effects of eight organizational support systems on virtual team effectiveness in five areas: communication, planning tasks and setting goals, solving problems and making decisions, resolving conflict, and responding to customer requirements. One hundred and eighty surveys were sent to information technology managers and collaborative team members, representing 43 companies. The results indicated that developing new roles for IT professionals and senior managers significantly increased virtual team effectiveness in several areas. The findings support the theory that organizations that utilize virtual teams must create high-level structures, policies, and systems to support the teams and the information tools they use.
