Virtual Teams and Technology: The Relationship between Training and Team Effectiveness

Description: 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.

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

Description: 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.

Present Absence: A work for string quintet and live electronics

Description: 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

Description: 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.

Accent and Grouping Structures in the String Quartets of Béla Bartók

Description: The music of Béla Bartók is defined in part by its unique blend of rhythmic vitality and inventiveness, and his string quartets offer a glimpse into a consistency of technique evident throughout his compositional career. Bartók's rhythmic environments are primarily metrical, but many of his rhythmic configurations are placed in such a way as to potentially override established meter. It is necessary, therefore, to institute an analytical means by which the delineation and comparison of rhythmic structures both within and without the metrical context may be accomplished. An analytical method using Timepoint Accent Structures (TAS) allows for the comparison of rhythms resulting from patterns of accent produced by pitch onset, dynamic stress, articulation or any other accentual factors. Timepoint Grouping Structures (TGS) delineate the number of timepoints present in alternating groups/blocks in a texture, thereby allowing for the recognition of patterning created by these larger groups. By applying TAS and TGS analysis, relationships of rhythmic equivalency, rotation, retrograde, complementation, augmentation, diminution, subset, superset, exchange, compression and expansion are clearly confirmed in the string quartets. In addition, symmetrical structures and arithmetic progressions are discovered. In many ways, Bartók's rhythmic organization mimics his procedures of pitch structuring.

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

Description: 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.

Factors that influence teacher turnover in Texas: Correlations with variables from the academic excellence indicator system for the year 1998-99

Description: The teacher shortage problem is a national and state concern. In 1998, the Texas State Board of Education Certification reported that school districts in Texas had to hire teachers to fill over 63,000 vacancies. Teacher resignations, other than retirement, contributed to over 46,000 teachers who left the profession about 19 % of the state's total teacher workforce. A significant number of Texas teachers left the profession in the first five years. The National Commission on Teaching and America's Future (1996) called the attrition of new teachers a chronic problem for American schools. Reducing the teacher shortage in Texas must begin with reducing the teacher turnover rate. Most studies concerning teacher attrition or turnover either address salary, or working conditions. Many of the studies deal with affective and subjective data regarding teacher turnover. The studies on teacher turnover often do not address quantifiable data collected uniformly across districts. Few studies address a comprehensive set of quantitative data to determine the variables associated with teacher turnover. This study addressed teacher turnover through quantitative research of data from the Texas Academic Excellence Indicator System (AEIS) with multiple analysis to provide insights to teacher turnover conditions and trends. The population for the study included all 1042 Texas school districts, and 61 Charter schools. The Academic Excellence Indicator System (AEIS) was used to determine the variables and supply data for the study. The study addressed only district data not individual school or campus data. The data captured for this dissertation were analyzed using descriptive statistics, correlational methods, and regression tools of research.

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

Description: 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.

American Choral Music in Late 19th Century New Haven: The Gounod and New Haven Oratorio Societies

Description: 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.

Symphony No. 1

Description: Symphony No. 1 is an orchestral composition for twenty-four instrumental groups without percussion instruments. It was composed with Algorithmic Composition System software, which gives driving forces for composition to the composer through the diverse compositional methods largely based on physical phenomena. The symphony consists of three movements. It lasts about sixteen minutes and twenty-six seconds--five minutes and twenty-two seconds for the first movement, five minutes and forty seconds for the second movement, five minutes and twenty-four seconds for the third movement. Most musical components in the first movement of the symphony are considered embryos, which gradually begin developing through the second and third movements.

Eighteenth-Century French Oboes: A Comparative Study

Description: 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.

Spanish Relations with the Apache Nations East of the Río Grande

Description: This dissertation is a study of the Eastern Apache nations and their struggle to survive with their culture intact against numerous enemies intent on destroying them. It is a synthesis of published secondary and primary materials, supported with archival materials, primarily from the Béxar Archives. The Apaches living on the plains have suffered from a lack of a good comprehensive study, even though they played an important role in hindering Spanish expansion in the American Southwest. When the Spanish first encountered the Apaches they were living peacefully on the plains, although they occasionally raided nearby tribes. When the Spanish began settling in the Southwest they changed the dynamics of the region by introducing horses. The Apaches quickly adopted the animals into their culture and used them to dominate their neighbors. Apache power declined in the eighteenth century when their Caddoan enemies acquired guns from the French, and the powerful Comanches gained access to horses and began invading northern Apache territory. Surrounded by enemies, the Apaches increasingly turned to the Spanish for aid and protection rather than trade. The Spanish-Apache peace was fraught with problems. The Spaniards tended to lump all Apaches into one group even though, in reality, each band operated independently. Thus, when one Apache band raided a Spanish outpost, the Spanish considered the peace broken. On the other hand, since Apaches considered each Spanish settlement a distinct "band" they saw nothing wrong in making peace at one Spanish location while continuing to raid another. Eventually the Spanish encouraged other Indians tribes to launch a campaign of unrelenting war against the Apaches. Despite devastating attacks from their enemies, the Apaches were able to survive. When the Mexican Revolution removed the Spanish from the area, the Apaches remained and still occupied portions of the plains as late as the 1870s. ...

The Study of English, French, German and Italian Techniques of Singing Related to the Female Adolescent Voice

Description: 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

A study of the relationships between personality as indicated by the Myers Briggs Type Indicator and leadership strengths and weaknesses as identified by Skillscope

Description: The purpose of this study was to improve the quality of information used in leadership assessment and development programs. The study determined the relationships between personality type, as indicated by the Myers-Briggs Type Indicator (MBTI), and leadership strengths and developmental needs as measured by Skillscope. The study also determined the relationships between personality type and congruence between self-awareness of strengths and developmental needs and ratings by knowledgeable observers. The discriminate analysis of the Skillscope leadership feedback instrument compared with the selected personality types revealed that personal management was a strength for both ISTJs and ESTJs. The decision-making skill was a strength for ISTJs, and power/influence was determined to be a strength for ESTJs. The high energy/results oriented skill was determined to be a developmental need for ISTJs. There was agreement between ENTJs and other raters as they both saw interpersonal relationships as a strength for that type. INTJs underrated themselves in interpersonal relationships, and ISTJs underrated themselves in decision-making. Further study is recommended to expand the general body of knowledge of leadership development research. Of particular concern are methods to identify and explore developmental needs of leaders and how those needs can be addressed in training programs. Three hundred sixty degree feedback instruments should be further analyzed in an effort to explain the differences between raters. Of concern is the high percentage of ISTJ types, which reveals a need to expand research to include significant numbers of other personality types. Consideration should be given to studies that identify the unique contributions of gender to leadership skills and development, and the impact culture has on leadership in organizations. Although statistically significant research is difficult to obtain in the behavioral sciences, the effort is worthwhile as it provides information that allows leadership development decisions to be made based on dependable data.

Response Guided Errorless Learning with Normal Elderly

Description: This study investigates the use of response guidance for errorless learning of a perceptual motor task in normal elderly. It provides normative data for a study with stroke patients using this technique for cognitive rehabilitation. While errorless learning has been shown to be more effective on most tasks than trial and error learning for people with memory impairments, its use with normal individuals has received limited attention. The questions of interest were whether errorless training of the perceptual motor task was more effective for improving and retaining accuracy; and whether both accuracy and response speed were more resistant to the effects of increased cognitive demands. A sample of 43 normal elderly in the United Kingdom, ranging in age from 60 to 77, completed an assessment of intelligence, memory, and attention. They then received training, over two sessions one week apart, to mark the midpoint of Judd Arrows presented on a computer screen using a cross cursor moved by an active force feedback joystick (AFF). During training the errorless group received AFF guidance to the correct midpoint, while the errorful group received none, and both received auditory and visual knowledge of results. There was no AFF during baseline or post test measures. Training was to criterion in each session with a discontinue rule if accuracy did not improve. At the end of session two both groups were given a cognitively challenging task concurrent with the arrow bisection. Results revealed that both groups improved their accuracy through training with the errorless group being significantly more accurate and tending to be faster in the final post tests of both sessions. The errorless group was significantly faster than the errorful group under the cognitive challenge, without sacrificing accuracy. These results suggest not only that AFF is an effective means of implementing errorless perceptual motor ...

A Comparison of Quantitative Skills in Texas Year-round Schools with Texas Traditional Calendar Schools

Description: This study analyzed the academic impact of year-round calendar schools as compared with the academic achievement of traditional calendar schools. The population studied was the 1998 public elementary schools in Texas. The academic impact was based upon the 1998 Texas Assessment of Academic Skills (TAAS) test administrated by the Texas Education Agency. The two groups of schools studied were Texas elementary schools that were on a year-round calendar schedule, and the Texas elementary schools on a traditional calendar schedule. Multiple regression statistics were used, in addition to means, and differences between the means of variables. Year-round schools (YRE), when compared to the means of traditional schools, have means lower in math scores (6.16 percent) than traditional schools. Year-round schools have fewer African Americans students (2.78%), White students (21.06%), and special education students (.25%). Year-round schools are higher in population size (72.72students), Economic Disadvantaged students (15.87%), Hispanic students (23.46%), and Mobility (3.23%).

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

Description: 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.

An NMR study of 2-ethyl-1-butyllithium and of 2-ethyl-1-butyllithium/lithium 2-ethyl-1-butoxide mixed aggregates

Description: A 1H, 13C, and 6Li NMR study of 2-ethyl-1-butyllithium indicated that 2-ethyl-1-butyllithium exists only as a hexameric aggregate over the entire temperature range of 25 to - 92.1 ° C in cyclopentane. Reacting 2-ethyl-1-butyllithium with 2-ethyl-1-butanol resulted in alkyllithium/lithium alkoxide mixed aggregates, apparently of the form Ra(RO)bLia+b. A multinuclear, variable temperature NMR study of samples with O:Li ratios of 0.2 and 0.4 showed, in addition to the alkyllithium, the formation of four mixed aggregates, one of them probably an octamer. Higher O:Li ratio samples showed the formation of several other mixed aggregates. Mixing 2-ethyl-1-butyllithium with independently prepared lithium 2-ethyl-1-butoxide formed the same mixed aggregates formed by in situ synthesis of lithium alkoxide. Lithium 2-ethyl-1-butoxide also exists as aggregates in cyclopentane.

Factors Affecting Resistance to Change: A Case Study of Two North Texas Police Departments

Description: This study focuses on four common factors believed to affect resistance to change in public organizations. It contributes to existing literature by examining the effect of higher education and trust on the police officer's level of resistance to change and the effects of participation and communication on trust. 286 police officers from two north Texas towns responded to the survey. Regression analysis and bivariate correlations were used to determine the relationship between, resistance to change, and participation, trust, communication, information, and education and the relationship between trust and the other independent variable. The analysis failed to support previous research, which listed participation as the most important factor, but did support the concept that participation and communication improved trust.

A Comparative Analysis of the Effectiveness of Three Different GED Preparation Programs

Description: The purpose of this study was to identify effective instructional programs for GED tests preparation for students in a large suburban school district. Three different nonrandom, unequal naturally occurring instructional groups at three different locations were examined. One group participated in a traditional instruction program, a second group in a test/retest program, and a third group in a computer-assisted program. The demographics of the district population, the GED population, and the individual study groups were catalogued and analyzed. The demographics of the GED population were similar to the district population but different from the GED passers. Student characteristics did affect GED success. Both quantitative and qualitative data were gathered. Random students in each of the three groups were interviewed about their experiences in GED preparation using a questionnaire. Quantitative data were analyzed using frequencies, means, correlations, and a multiple regression analysis. Since the GED credential is an alternative to the high school diploma, its use as a dropout alternative is important to every school district. The study found that instructional methods had little impact on students' success in receiving the GED credential. The overall success rate of students was low in each group. The student's reading achievement score, GPA, and IQ score were predictors of GED tests success. Little research has been done in the area of GED instruction; perhaps this lack of work is due to the known limited effectiveness of GED preparation. Districts hoping to build effective GED programs should screen students prior to admission to a GED program. High school GED instruction seems to be effective for students likely to be successful in the regular school setting but in need of an immediate credential because of pregnancy or parenting or the need to work full-time or the desire to begin college study. Districts should also design programs ...

Optimism, Health Locus of Control, and Quality of Life of Women with Initial versus Recurrent Breast Cancer

Description: Health Locus of Control (HLOC) and other predictors of Quality of Life (QL) were examined for women with an initial versus recurrent breast cancer diagnosis. Twenty-eight women with an initial breast cancer (IBC) diagnoses and twenty-eight women with recurrent breast cancer (RBC) diagnoses were recruited from doctors' offices and cancer support groups. Correlational analyses were used to assess the relationships between variables. No significant differences were found between women with IBC and RBC on Psychological QL. Doctor HLOC and Psychological QL were related for women with RBC (r = .481, p = .01) and marginally so for women with IBC (r = .329, p = .09). A positive correlation was also found between Doctor HLOC and Functional QL for both women with IBC (r = .464, p = .01) and women with RBC (r = .390, p = .04). After controlling for stage of cancer, women with RBC reported higher Functional QL than did women with IBC. Advanced (stages III or IV) versus early (stages I or II) cancer stage related to lower Functional QL, controlling for initial versus recurrent diagnosis (r = -.283, p = .01). A marginally significant relationship was also found for cancer stage, regardless of initial versus recurrent diagnosis, with higher Overall QL for women with early stages of breast cancer (r = -.157, p = .09). No significant differences in Optimism or Overall QL were found between women with IBC versus RBC. No differences were found between married and single women. This research begins to explore differences in Quality of Life for women with a new versus a recurrent breast cancer diagnosis.

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

Description: 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.

Hardiness, stress, and coping strategies among mid-level nurse managers: Implications for continuing higher education.

Description: This study investigated relationships among hardiness, stress, and coping strategies among mid-level nurse managers in hospitals. Coping strategies were hypothesized to be positively related to stress. In addition, hardiness and its components were hypothesized to be positively related to stress and coping strategies. Demographics were hypothesized to be unrelated to stress, hardiness, and coping strategies. Both hardiness and coping strategies were hypothesized to be predictors of stress. Pearson correlation coefficients, multiple regression, and linear regression were used in data analysis. Stress was associated with specific coping strategies viz., confrontation, selfcontrolling, accepting responsibility, and escape-avoidance. High hardiness, particularly commitment and challenge, was associated with low levels of stress and with problemfocused coping strategies. By contrast, low hardiness was associated with high stress and use of emotion-focused strategies. Significant demographics, when compared to study variables, included age, experience, time with supervisors, number of direct reports, highest degrees obtained, and formal or informal higher education in management. Young nurse managers who were less experienced in nursing and management, and who had fewer direct reports, reported the highest stress levels among nurse managers. High hardiness, particularly commitment, was a strong predictor of low levels of stress; use of escape-avoidance was a significant predictor of occupational stress. This study supported the theoretical suppositions of lower stress if hardiness and specific coping strategies are high among mid-level nurse managers. Potential exists for work-related stress to be reduced by increasing hardiness and adaptive coping strategies. Implications for higher education research and practice are discussed.
