Eighteenth-Century French Oboes: A Comparative Study
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.

American Choral Music in Late 19th Century New Haven: The Gounod and New Haven Oratorio Societies
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 Study of English, French, German and Italian Techniques of Singing Related to the Female Adolescent Voice
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

Identification of environmental determinants of behavior disorders through functional analysis of precursor behaviors
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.

Assessment and Comparison of the Stress Experienced by International and American Students at the University of North Texas
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.

By Air Power Alone: America's Strategic Air War in China, 1941-1945
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.

Fathers' and mothers' childcare ideas and paternal childcare participation.
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.

The uninvestigated factors: Dimensions of personality and psychopathology in sex offenders
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.

Present Absence: A work for string quintet and live electronics
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.

Media Influence on Executive Police Decision-Making: A Case Study of Police and Media Interaction During the Oklahoma City Bombing Investigation and Trials
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.

The Effects of Cumulative Consumption Feedback On Demand For Money As A Commodity
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.

A Study of the Anti-Catholic Bias Contained Within Jacob Burckhardt's The Civilization of the Renaissance in Italy
This work examines the anti-Catholic bias of Jacob Burckhardt as he employed it in the Civilization of the Renaissance in Italy. A biographical chapter examines his early education in the Lutheran seminary and the influence of his educators at the University of Berlin. The Civilization is examined in three critical areas: Burckhardt's treatment of the popes in his chapter "The State as a Work of Art," the reform tendencies of the Italian humanists which Burckhardt virtually ignored, and the rise of confraternities in Italy. In each instance, Burckhardt demonstrated a clear bias against the Catholic Church. Further study could reveal if this initial bias was perpetuated through later "Burckhardtian" historians.

The Effects of Project PACE on Adolescent Females' Physical Activity Readiness
This study evaluated the effects of Project PACE, a program designed to increase physical activity, on the physical activity level and selected psychosocial variables of sedentary adolescent females ages 12 to 18. Psychosocial variables included self efficacy, attitude, perception of barriers, perceived social support, and knowledge. Of the 69 participants, 40 were enrolled in the treatment group and 29 were enrolled in the control group at the start of the study. The only significant differences were found for attitudes towards physical activity at base line. Findings from this study suggest that implementation of Project PACE protocol in school settings may produce some positive effects, but no significant findings were detected.

Construction of a Physical Map of Moraxella (Branhamella) catarrhalis Strain ATCC25238
In order to gain a better understanding of this microorganismand its role in human pathogenesis, a physical map of Moraxella catarrhalis type strain ATCC25238 was constructed using pulsed field gel electrophoresis (PFGE) in combination with Southern hybridization techniques. Restriction endonucleases Not I, Rsr II, and Sma I were used to digest the chromosomal DNA. An overlapping circular map was generated by cross-hybridization of isolated radiolabeled fragments of Moraxella catarrhalis genomic DNA to dried PFGE gels. The number and location of the 16S and 23S ribosomal RNA genes were determined by digestion with l-Ceul enzyme and by Southern hybridization. Virulence-associated genes, the gene for β-lactamase, and housekeeping genes were also placed onto the physical map.

A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, Texas Based on Chlorophyll A
Two years before impoundment, the trophic status of Lake Ray Roberts was predicted by applying the total phosphorus input into the Organization for Economic Cooperation and Development (OECD) eutrophication model. Predicted mean summer epilimnetic (MSE) chlorophyll a of Elm Fork arm, Isle duBois arm and Main Body were in the eutrophic category of the OECD model. Observed MSE chlorophyll a two years after impoundment of Elm Fork arm, Isle duBois and Main Body had not reached their predicted means and were at the mesotrophic-eutrophic boundary of the OECD model. Six years after impoundment, observed MSE chlorophyll a for Main Body, was closer to its predicted mean and in the eutrophic category of the OECD model. Six years after impoundment, Elm Fork arm was the most productive area of Lake Ray Roberts. Observed means of chlorophyll a, total phosphates, suspended solids and turbidity were often highest in the Elm Fork arm. Wastewater effluent from Gainesville and Valley View, TX, had an impact on productivity in Elm Fork arm.

A Laboratory Study of the Asiatic Clam (Corbicula fluminea Müller) as Influenced by Substrate, Food Source and Water Type
Growth of Corbicula fluminea was monitored in the laboratory. Three experiments were conducted. Experiment I utilized three substrates and one food type. Experiment II utilized three substrates and two food types. Experiments I and II were conducted to determine if substrate type or food type effected growth. Experiment III used no substrates, one food type and was conducted to determine growth response to different types of water. Clams were maintained in three substrates: sand, gravel and clay. Clams were also maintained without substrate. Growth was monitored by measuring shell length (mm) and recording the weight (mg) of clams over a period of thirty days. At the end of the test period data were evaluated for normality and homogeneity.

AIDS Preventative Behavior Among Taiwanese University Students
This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.

A Two Semester Life Science Syllabus for Use in Texas Public Schools with Seventh Grade Students
The problem of using a state adopted textbook written to apply to a large body of students with varying interests and needs was overcome by using a detailed syllabus that arranged course content in a meaningful sequence that appealed to student interest. The outlined syllabus prepared a two semester life science curriculum to be used by the teacher to guide lesson planning. Both semesters were divided into three units each. Materials included in the syllabus were given to actual student groups in real classroom settings. Since hands on learning was an important part of classroom instruction, two laboratory sections were included in the appendices to be used with the syllabus.

An Examination of Strain Among Community Police Officers in Northumbria, England
This paper examines some causes of strain and frustration among police officers. Previous research suggests that police officers sufferfromthe lack of communication and support from their community. The failure of communication has caused turmoil in the past between communities and their police. A possible solution is community policing. Community policing is supposed to establish communication between the public and the police. Causes of strain and frustration among the police are discussed along with the possible benefits of community policing. Research has shown that community police officers suffer less strain and frustration than their brethren. On this premise a quantitative examination a police force in Northumbria, England was conducted. The quantitative analysis focuses on two groups; community police officers and police officers not involved in community policing.
