Groupware packages are increasingly being used to support content delivery, class discussion, student to student and student to faculty interactions and group work on projects. This research focused on groupware packages that are used to support students who are located in different places, but who are assigned group projects as part of their coursework requirements. In many cases, students are being asked to use unfamiliar technologies that are very different from those that support personal productivity. For example, computer-assisted cooperative work (CSCW) technology is different from other more traditional, stand-alone software applications because it requires the user to interact with the computer as well as other users. However, familiarity with the technology is not the only requirement for successful completion of a group assigned project. For a group to be successful, it must also have a desire to work together on the project. If this pre-requisite is not present within the group, then the technology will only create additional communication and coordination barriers. How much of an impact does each of these factors have on the acceptance of CSCW technology? The significance of this study is threefold. First, this research contributed to how a user's predisposition toward group work affects …

The topic of alternative schools is widely available in the literature; however, once a student has been labeled a "troublemaker" and has been placed in a District Alternative Education Program (DAEP), a Type II setting, there is limited information about the overall success of students upon their return to the mainstream. This study compared the success of students formerly placed in a modified disciplinary Type II setting, once they have returned to the mainstream, with their success prior to disciplinary placement. The purpose of the study was to examine if disciplinary measures that remove students from the mainstream environment negatively impact the variables that measure school success, despite legislative mandates such as No Child Left Behind, which advocates success for every student. The population for this study was 86 7th- through 11th-grade students assigned to a DAEP in Texas during the spring of 2003. A comparison of pre- and post-placement dependent variables measuring school success-attendance, passing core courses, behavioral achievement, standardized test score achievement, recidivism, and dropout rates-comprised this study. The independent variables-gender, ethnicity, grade level, socioeconomic status, and disciplinary offense-were used to compare and analyze each dependent variable. The dependent variables of attendance, passing core courses, and behavior demonstrated …

The present study sought to identify variables that predicted parental decision-making regarding their child's participation in a national gifted and talented identification program for middle school students and subsequent participation in recommended educational options. One hundred sixty-nine parents of students who qualified for either the 2001-2002 or 2002-2003 Duke Talent Identification Program participated in the study. The students were drawn from two large public school districts and six small private schools in a large metropolitan area in the southwestern United States. Both quantitative and qualitative methods were used to identify the variables predictive of parental decision-making regarding talent search participation. Each parent completed a questionnaire consisting of both multiple-choice and open-ended questions. Selected parents participated in structured follow-up interviews. The results of the study indicated that parental perception of the helpfulness of school personnel in explaining the purpose and process of the talent search was most predictive of participation in the talent search. The educational level of the father, parent's prior awareness of the purpose and process of talent search, and the number of enrichment activities in which the child had previously participated were also predictive of talent search participation. Qualitative data indicated that parents of both participants and nonparticipants …

The stonefly genus Isogenoides is revised following a holomorphological approach utilizing traditional morphology and behavioral lines of evidence. Species keys are provided for all life stages. One species, I. krumholzi (Ricker) is considered a synonym of I. doratus (Frison). Detailed species descriptions are provided for males, females, nymphs and ova. Distributions are updated utilizing all known published accounts and materials examined. The vibrational communication (drumming) behavior is reported for males and all but one species for females. The signals were species-specific and ranged in complexity from ancestral sequenced duets to derived grouped exchanges. I. olivaceus is least specialized, having mostly sequenced duets, and I. zionensis most specialized, displaying ancestral sequenced, derived grouped and complex derived exchanges containing both sequenced and grouped elements. Laboratory egg incubation experiments over a 2-4 year period show that Isogenoides has a great capacity for extended, sometimes-asynchronous diapause and hatching. The eggs of six species were incubated at a single, ca. simulated San Miguel River, Colorado, seasonal temperature regime. Direct hatch within two weeks occurred only for I. zionensis (Leopard Creek, Colorado) with small numbers hatching again after one, two, and four years. Eggs of I. doratus and I. varians hatched after an over summer, 3-5 …

The popularity of the clarinet in Spain is second only to that of the guitar, and there is a rich tradition of clarinet playing that is accompanied by an equally rich repertoire of music for the clarinet by Spanish composers. The works for clarinet and piano by Miguel Yuste (1870-1947) are among this little known repertoire. In the early twentieth century it was thought that Miguel Yuste wrote over one hundred works for clarinet. However, current research suggests that this is incorrect. What is known is that seven works for clarinet and piano have been published. Miguel Yuste and his music are pivotal in the establishment of the strong clarinet tradition for which Spain is presently known. In his thirty years as the clarinet professor at the Real Conservatorio Superior de Música de Madrid (1910-1940), Miguel Yuste's music and pedagogical ideas became, and continue to be among the foundations of Spanish clarinet playing. This project discusses each published work and presents current research on the works composed for clarinet and piano by Miguel Yuste. After a brief history of Spain's music and social climate in which it developed (Ch. 2), this document discusses the introduction of the clarinet in Spain, …

This research examines the coping processes of African American women with breast cancer and how those processes relate to low usage of cancer support groups by these women. Prior coping research has utilized predominantly White samples. The limited research on African American coping responses is conflicting and characterized by small samples and non-probability sampling techniques. In this study, 26 respondents from Central and North Texas metropolitan areas were interviewed, including 9 key informants, 9 African American breast cancer survivors, and 8 White survivors. The data suggest that African American and White women cope with breast cancer in significantly different ways. Culture appears to account for the differences. All African American breast cancer survivors identified faith as their primary coping strategy. In contrast, only half of the White survivors claimed faith as their primary coping strategy, but like the other White survivors, tended to rely on multiple coping strategies. The African American survivors conceptualized God as an active member of their support network. Most prayed for healing, and several attributed examples of healing to God's intervention. The White survivors found God's presence in the actions of other people. They prayed for strength, peace, and courage to endure the illness. The use …

Though increasing numbers of women are entering the workforce, a disproportionate number of women are placed into upper level management positions. Social role and role congruity theory both posit that women in leadership positions are likely to face more negative criticism than men in leadership positions. The purpose of the current study was to examine the influence of gender roles on leader behaviors as well as leaders' self perceived effectiveness. The study also examined third party raters' views of female and male leaders. Videotapes of forty-seven mixed sex groups with randomly appointed male and female leaders were used to examine leader behaviors as well as raters' effectiveness ratings. Leaders' self perceived effectiveness ratings were also used. Gender roles of the leaders were assessed using the Bem Sex Role Inventory (BSRI). Results of a MANOVA indicated that leader gender roles did not lead to differences in leader behaviors exhibited among those in feminine, masculine, and androgynous groups. For female leaders, femininity was not related to feminine behaviors. Unexpectedly, for male leaders, masculinity was inversely related to masculine behaviors. With regard to raters' effectiveness ratings of the leaders, no differences were found in ratings based on leader gender. Further, for female leaders, …

The purpose of this study was to identify high performing school districts in Texas and to determine if there are different characteristics leading to the provision of an adequate education in high performing districts as compared to low performing districts. It specifically sought to determine which characteristics contributed most to an adequate education and used data from the Texas Academic Excellence Indicator System (AEIS) which chronicled scores on the Texas Assessment of Academic Skills (TAAS). The population for this study consisted of all 2001-2002 Texas public school districts with the exception of charter schools, special-purpose statutory districts, and state-administered districts, which resulted in using data from 1027 Texas school districts. Descriptive discriminant analysis was chosen as the method for statistical analysis. Data were obtained from the Texas Education Agency (TEA). Adequate and inadequate districts were analyzed according to eight variables. They were (1) taxable value per pupil, (2) the percentage of special education students, (3) the percentage of students coded as bilingual and ESL, (4) pupil-teacher ratio, (5) the size of the district, (6) the percentage of economically disadvantaged students in the district, (7) the district community type, such as rural or suburban, and (8) the total operating expenditures per …

Methods to determine genetic diversity and relatedness within populations are essential tools for proper wildlife management. Today the approach of choice is polymerase chain reaction-based microsatellite analysis. Seven new polymorphic loci were isolated from a microsatellite-enriched Caribbean flamingo genomic library and used to characterize survey populations of Caribbean and African greater flamingos. In addition, four of these loci were used to verify parentage relationships within a captive-breeding population of African greater flamingos. Parentage predictions based upon gamekeeper observations of breeding and nesting did not always agree with genetic-based parentage analyses of the nine suggested family groups. Four family groups were supported (groups I, II, III and VI) by there results. However, an analysis of the remaining five suggested groups, with a total of eight offspring/dam and eight offspring/sire suggested relationships, yielded seven exclusions of the suggested dam and six exclusions of the suggested sire. This put the overall suggested dam exclusion rate at 35% and exclusion rate for suggested sires at 29%. Although the keeper observation data for our family groups must be considered a variable of concern at this time, these findings are certainly suggestive that more carefully controlled studies may reveal that flamingos are not monogamous as long …

When the Bush administration set out to revolutionize public education through the requirements commanded by No Child Left Behind Act of 2001 (NCLB), framers of the legislation chose language that appeared inclusive of all students in U.S. schools. The law demands that English language learners take the mandated exams early in their academic careers in the United States even though research indicates most will fail due to lack of time to acquire sufficient language proficiently to demonstrate their learning on the exams. Viewed through a critical theory lens, the inclusive nature of NCLB is in fact, oppressing ELL students. One district in Texas The study involved ELL students in grades 1-12 in a school district in North Central Texas that uses its family literacy center as an intervention to aid ELL families in English language acquisition. Students fell into three categories: students and parents who attend the family literacy center English classes, students whose parents attend the family literacy center English classes but the students do not attend, and students and parents who do not attend the family literacy center English classes. The quantitative data for the study were reading and math Texas Assessment of Knowledge and Skills (TAKS) and …

Two series monodispersed nanoparticles of hydroxylpropyl cellulose (HPC) and functionalized poly-N-isopropylamide (PNIPAM) particles have been synthesized and used as building blocks for creating three-dimensional networks, with two levels of structural hierarchy. The first level is HPC nanoparticles were made from methacrylated or degradable cross-linker attached HPC. These nanoparticles could be stabilized at room temperature by residual methacrylate or degradable groups are present both within and on the exterior of HPC nanoparticles. Controlled release studies have been performed on the particle and networks .The nearly monodispersed nanoparticles have been synthesized on the basis of a natural polymer of hydropropylcellulose (HPC) with a high molecular weight using the precipitation polymerization method and self-assembly of these particles in water results in bright colors. The HPC nanoparticles can be potential using as crosslinkers to increase the hydrogels mechanical properties, such as high transparency and rapid swelling/de-swelling kinetics. The central idea is to prepare colloidal particles containing C=C bonds and to use them as monomers - vinylparticles, to form stable particle assemblies with various architectures. This is accomplished by mixing an aqueous suspension of hydrogel nanoparticles (PNIPAM-co-allylamine) with the organic solvent (dichloromethane) to grow columnar crystals. The hydrogels with such a unique crystal structure behavior …

Voluntary turnover has historically been a problem for today's organizations. Traditional models of turnover continue to be utilized in a number of ways in both academia and industry. A newer model of turnover, job embeddedness, has recently been developed in an attempt to better predict voluntary turnover than existing models. Job embeddedness consists of organizational fit, organizational sacrifice, and organizational links. The purpose of this study is to two fold. First, psychometric analyses were conducted on the job embeddedness model. Exploratory factor analyses were conducted on the dimensions of job embeddedness, which revealed a combined model consisting of five factors. This structure was then analyzed using confirmatory factor analysis, assessing a 1, 3, and 5 factor model structure. The confirmatory factor analysis established the use of the 5 factor model structure in subsequent analysis in this study. The second purpose of this study is to compare the predictive power of the job embeddedness model versus that of the traditional models of turnover. The traditional model of turnover is comprised of job satisfaction, organizational commitment, and perceived job alternatives. In order to compare the predictive power of the job embeddedness and traditional model of voluntary turnover, a series of structural equation …

This project investigated the relations between recalled job-satisfaction, ability, and task demands in Vietnam era helicopter aviators. It attempted to detect and describe factors present in a dangerous combat environment which may influence some individuals to enjoy and take satisfaction at being exposed to, creating, and participating in the dangerous and life threatening violence involved in helicopter combat. Participants were 30 pilots and crew members retired from the 335th Assault Helicopter Company who were all actively involved in combat in Vietnam from 1968 to 1970. This study found that developing a love of war is correlated with anger during combat. The love of war is not correlated with PTSD processes nor is it correlated with specific personality dimensions. The love of war research is a new area. The questions were used to operationalize the love of war represent a significant limitation. This method of operationalizing the love of war concept does not make fine discriminations has questionable content validity. To facilitate accuracy in discriminating between participants when conducting future research in the area, researchers could benefit from constructing a measure with greater content validity.

What does it take for organizations to support people working together effectively? What does it mean for an organization to be effective? Does successful collaboration lead to more effective organizations? This study explored these questions both theoretically and empirically in an effort to help organizations understand the most important aspects to consider when attempting to achieve collaboration for organization success. The purpose of this study was to fill some of the gaps in the research by taking a broad, holistic approach to exploring the context required to support collaboration at levels of organizations broader than the team and exploring the links between organization support of collaboration and organization effectiveness. In preparation for the current study, the Organization Support of Collaboration model was developed to identify the broad organization design elements that are required to support collaboration. The Organization Effectiveness model was created to provide a holistic view of what it takes for an organization to be considered effective. The present study empirically validated these models and explored the links between them. Data was collected via a web-based questionnaire administered to a broad sample of individuals who work in organizations. Results supported a model of Organization Support of Collaboration with six …

Counselor education program faculties evaluate applicants to masters and doctoral level programs using criteria that the faculties hope will predict the applicant's potential for academic success and then effectiveness as a counselor, counselor educator, or researcher. Choosing admission criteria to assess this level of potential in an applicant is quite a task. Those counselor education programs that are accredited by the Council for Accreditation of Counseling and Related Educational Programs (CACREP) have the benefit of the admission guidelines provided by CACREP standards for accreditation. These guidelines give only basic, general direction to programs regarding their admission criteria but each individual program determines their own criteria for admission. The purpose of this study was to discover any recognizable trends in admission policy criteria, in terms of specific criteria used to evaluate and select students from the applicant pool, for CACREP accredited masters and doctoral programs. This study also sought to discover any recognizable trends in admission policy criteria, in terms of a specific number of criteria used to evaluate and select students for CACREP accredited master and doctoral counselor education programs. This qualitative study investigated 178 masters level CACREP accredited counselor education programs and 45 doctoral CACREP accredited counselor education programs. …

Award-winning composer John Musto stands at the forefront of modern American art-song composition. Many of his songs, such as "Litany" from Shadow of the Blues, have already achieved a place in the standard contemporary repertory for singers. His compositional technique weaves influences of jazz, blues, ragtime, and popular music with classical technique to make music that is decidedly modern but accessible and well liked both by critics and audiences. Unfortunately, though he is still actively composing, very little has been written about Musto and there is a lack of information available about his more recent compositions. This performance guide addresses one of Musto's acclaimed song cycles, Penelope, (a cycle of seven songs for soprano and piano) commissioned and premiered in 2000. The story of the cycle is an updated version of the character Penelope from Homer's The Odyssey and was a collaboration between Musto and poet Denise Lanctot. Including interviews with Musto, and his wife, soprano Amy Burton, who premiered the cycle and for whom it was written, the document provides background information on how the cycle was conceived and gives in-depth performance information on each of the seven songs of Penelope. In addition to musical examples and poetry from …

Traditionally, social network analysis (SNA) techniques enable the examination of relationships and the flow of information within networks of human members or groups of humans. This study extended traditional social network analysis to include a nonhuman group member, specifically a document retrieval system. The importance of document retrieval systems as information sources, the changes in business environments that necessitates the use of information and communication technologies, and the attempts to make computer systems more life-like, provide the reasons for considering the information system as a group member. The review of literature for this study does not encompass a single body of knowledge. Instead, several areas combined to inform this study, including social informatics for its consideration of the intersection of people and information technology, network theory and social network analysis, organizations and information, organizational culture, and finally, storytelling in organizations as a means of transferring information. The methodology included distribution of surveys to two small businesses that used the same document retrieval system, followed by semi-structured interviews of selected group members, which allowed elaboration on the survey findings. The group members rated each other and the system on four interaction criteria relating to four social networks of interest, including awareness, …

This document includes a brief biography of Johan Helmich Roman, a discussion about the two most important manuscripts of Then Svenska Messan, or The Swedish Mass, and a discussion concerning the circumstances of the first performance of this work. Roman was a prolific composer of instrumental works for various ensembles and solo instruments. He wrote a smaller amount of vocal music and even less choral music; however, most of his music for choirs, vocal ensembles, and vocal soloists featured the Swedish language. The composer advocated the establishment of uniform rules of Swedish spelling and grammar. He also sought to develop and expand the genre of Church music in the Swedish vernacular. This document focuses on the composer's attention to the nature of the Swedish language when setting the text.

In recent years, few laws have had greater impact on public education than Title IX of the Education Amendments of 1972. As a result of this legislation, participation levels of female athletes have risen dramatically. Conducted in the Texas Education Agency's Region XI, this study sought to ascertain the perceptions of high school principals, the lead coaches of male athletes, and the lead coaches of female athletes with regard to their schools' compliance with the components of Title IX. The study centered on the results of a survey instrument that included twenty Likert-scale questions as well as several demographic questions. The research questions sought to determine: (1) respondents' overall perception of compliance; (2) any differences in perceptions of compliance based upon the role of the individual; (3) any differences in perceptions based upon the percentage of students qualifying for free and reduced lunch; (4) any differences based upon the state classification of the schools; (5) any differences based upon the gender of respondents; (6) whether complaints filed via OCR result in a perception of increased compliance; and (7) the program component areas in which respondents view their schools to be most compliant. Descriptive and causal-comparative methods were used to analyze …

Flamingo species generate tremendous interest whether they are small captive groups or wild populations numbering in the thousands. Genetic pedigrees are invaluable for maintaining maximum genetic diversity in captive, as well as wild, populations. However, presently there is a general lack of genetic data for flamingo populations. Microsatellites are loci composed of 2-6 base pair tandem repeats, scattered throughout higher eukaryotic genomes, often exhibiting high levels of polymorphism and heterozygosity. These loci are thus important genetic markers for identity, parentage and population studies. Here, six microsatellite loci were isolated from a microsatellite-enriched Caribbean flamingo partial genomic library. Two are compound complex repeats and four are perfect trinucleotide repeats. Each locus was amplified from Caribbean, African greater, Chilean and lesser flamingo genomic DNAs. Heterozygosity frequencies were calculated for Caribbean (range 0.12-0.90) and African greater flamingos (range 0.23-0.94) loci. All six microsatellite loci were found to be in Hardy-Weinberg equilibrium and linkage disequilibrium analyses did not suggest linkage for any pair of two greater flamingo subspecies (African and Caribbean) loci. At least five of the loci also exhibit polymorphism in Chilean and lesser flamingos, but due to small sample numbers, relevant allele/heterozygosity frequency calculations could not be estimated. Nucleotide sequence comparisons of …

In this study the author addresses the problem of finding quality repertoire for young college-level saxophonists. By examining graded repertoire lists from a variety of college and university saxophone instructors, the author has compiled a list of 180 works for alto saxophone and piano. Twenty-four well-known works of a difficulty-level appropriate for freshman and sophomore players are identified and annotated. Each annotation consists of bibliographical information, a biographical sketch of the composer, a difficulty rating of eight elements of performance, a discussion of performance considerations, and a bibliography of available recordings. The eight elements of performance included in the difficulty rating are: Meter, key signatures, tempo, note-values, rhythm, articulation, range, and dynamic levels. Each of these facets is graded using a six-point difficulty scale. One work from the select list, Yvon Bourrel's Sonate Pour Saxophone Alto et Piano, has been analyzed in greater detail with regard to thematic material and key areas to provide in-depth information that, hopefully, will help the student gain a deeper understanding of that work and as a result perform the piece with greater artistry.

This study identified and described the experiences of twelve African American men that influenced the choice to participate in postsecondary education. This qualitative study used a phenomenology framework to determine 1) the formation of predisposition in the college choice process, 2) the messages received about college from influential people, and 3) perception and interpretation of the importance of a college degree. The overall theme arising from the data is that the college choice process was complicated and inconsistent; however, ten of the twelve participants completed some type of postsecondary training. Deficient messages about postsecondary education manifested as low parental support for college attendance, low academic expectations, withholding of important information from school officials and little or no exposure to postsecondary institution campuses or students. Influential people for the participants ranged from parents to themselves, and from a combination of characteristics from different people, to peers, to no one. The informants did not consistently identify their role model as the one who influenced them to attend college. The perception of the value of a college degree varied among the participants. Some described the degree as a requirement for success; others felt that strengthening family and achieving financial independence was more important.

Managing water quality aspects requires the use of integrative tools that allow a holistic approach to this problem. Water quality models coupled to hydrodynamic models are these tools. This study presents the application of the water quality model WASP coupled to the hydrodynamic model DYNHYD for two distinct reservoirs: Lake Texoma and Tocoma Reservoir. Modeling the former included simulations of water velocities, water level, and four chemical and physical compounds: chlorides, dissolved oxygen (DO), biochemical oxygen demand (BOD), and total suspended solids (TSS); and validation of the results by comparing with observed values during March - May, 1997. The latter is still under project status and the simulation was performed in a prospective way. The analysis included simulations of water velocities under current and for expected conditions, DO and BOD. Both models, DYNHYD and WASP, fitted pretty well to observed conditions for Lake Texoma and for where Tocoma Reservoir has been planned. Considering management and decision support purposes, the role of boundary and loading conditions also was tested. For Lake Texoma, controlling boundary conditions for chlorides is a determinant factor for water quality of the system. However, DO and TSS in the reservoir are governed by additional process besides the …

This study focused on the identification of career paths that led to the Texas public school superintendency, including an examination of career path differences associated with gender, ethnicity, and district type, and on the identification of the career path positions superintendents perceived as being the most beneficial in preparing them for the superintendency. Additionally, the study examined place-bound versus career-bound superintendents. The most common career path to the Texas public school superintendency was secondary teacher, secondary principal, and superintendent. Female administrators and administrators who worked in large districts were more likely to take the director route to the superintendency. Additionally, most major urban superintendents took the director route to the superintendency. Ethnicity was not a significant factor in determining the career path to the superintendency. A significant correlation did exist between educational attainment and the secondary teacher, secondary assistant principal, secondary principal, assistant superintendent, superintendent career path. A higher representation of superintendent respondents who held earned doctorates existed in that career path than in any of the other career path groups. While educational attainment was important in higher paying districts, most Texas superintendents did not hold doctorates. Few held doctorates from the most prestigious, nationally recognized universities.
