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.
Knowledge workers are an important resource for the typical modern business firm, yet financial reporting ignores such resources. Some researchers contend that the accounting profession has stressed reliability in order to make the accounting appear objective. Others concur, noting that accounting is an insecure profession and adopts strict rules when faced with uncertainty. Accountants have promulgated a strict rule to expense human resource costs, although many know that such resources have future benefits. Some researchers suggest that any discipline must modify its language in order to initiate change toward providing useful social ameliorations. If accounting theorists extend this idea to the accounting lexicon.s description of investments in human resources, investors and other accounting user groups might gain greater insight into how a firm fosters and nourishes human capital. I tested three hypotheses related to this issue by administering an experiment designed to assess financial analysts. perceptions about alternative financial statement treatments of human resources in an investment recommendation task. I predicted that (1) analysts' perceptions of the reliability (relevance) of the information they received would decrease (increase) as the treatment of human resources increasingly violated GAAP (became more current-oriented), (2) analysts exposed to alternative accounting treatments would report a lower likelihood of recommending that their clients invest in the company in the task, and (3) financial analysts who ranked reliability (relevance) as a more important information quality would be less (more) likely to recommend that their clients buy the stock represented in the case because the treatment of human resources on the financial statements violated GAAP (was more current-oriented) as compared to analysts who ranked reliability (relevance) as being lower (higher) in importance. Analysts receiving financial statements with accounting treatments of human resource costs that violated GAAP judged such information as less reliable and were also less likely to recommend …
GABAA receptor binding is transiently increased in rat whisker barrels during the second postnatal week, at a time when neurons in the developing rat cortex are vulnerable to excitotoxic effects. To test whether these GABAA receptors might serve to protect neurons from excessive excitatory input, polymer implants containing the GABAA receptor antagonist bicuculline were placed over barrel cortex for a 4-day period in young (postnatal days 8 - 12) and adult rats. In the cortex of young, but not adult rats, the chronic blockade of GABAA receptors resulted in substantial tissue loss and neuron loss. The greater loss of neurons in young rats supports the hypothesis that a high density of GABAA receptors protects neurons from excessive excitatory input during a sensitive period in development.
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 purpose of this study was to identify and analyze sales people's perceptions of performance appraisal criteria in a telecommunications corporation. The study was prompted by the perceived disillusionment of the sales people with the current performance appraisal criteria. The perceptions of 67 sales people were assessed using a questionnaire developed by the researcher. One-way analysis of variance procedures (ANOVA) were used to determine if there were statistically significant differences in premise and telemarketing sales people's perceptions of performance appraisal criteria. Findings indicated that there were no statistically significant difference in premise and telemarketing sales people's perceptions of the 38 performance appraisal criteria statements. Findings did not indicate a statistically significant difference in premise and telemarketing sales people's perceptions of the performance criteria statements, the attitude or satisfaction statements, and the peripheral issue statements. Based on this study, the sales people appear to have clear perceptions of the performance appraisal criteria.
Ninety elementary public school teachers were surveyed to find out where they obtained their teaching ideas. Seven popular elementary-level teaching periodicals, dated 1989-1999, were analyzed for aging-related content, and compared with 27 of the National Academy for Teaching and Learning about Aging (NATLA) aspects of aging recommended for students' learning. Results indicate that public elementary teachers obtain their teaching ideas from various places: teaching institutes or workshops; other teachers; ideas or lessons they develop themselves; and teaching periodicals. A large percentage obtain lesson ideas from teaching periodicals that they browse or read. This finding may assist NATLA in making recommendations to particular editorial boards. Surprisingly, few teachers obtain their teaching ideas from state and local curricular mandates. When the periodical issues were analyzed, aging-related content was categorized in four ways: informational articles with selected teaching or learning activities; articles describing intergenerational programs or activities; book reviews with selected learning activities; and book review titles mentioning older adult characters. Category totals among the 7 periodicals were highest in book review titles mentioning older adult characters and book reviews with selected learning activities. The content was compared to NATLA's recommendations for students' learning. The findings were not significant. The aging aspect that appeared most often in book reviews with selected learning activities was that most living things have life cycles of patterned biological changes, and/or that death and disability can occur at any age. Whether we formally teach them about aging or not, children learn about it. Earlier studies indicate that even preschool children may stereotype the aging process and/or older adults. Curricular and instructional ideas provided in teaching materials, even in an informal format can provide education, which prepares children for real life experiences.
Companies have invested large amounts of money on information systems development. Unfortunately, not all information systems developments are successful. Software project failure is frequent and lamentable. Surveys and statistical analysis results underscore the severity and scope of software project failure. Limited research relates software structure to information systems failures. Systematic study of failure provides insights into the causes of IS failure. More importantly, it contributes to better monitoring and control of projects and enhancing the likelihood of the success of management information systems. The underlining theories and literature that contribute to the construction of theoretical framework come from general systems theory, complexity theory, and failure studies. One hundred COBOL programs from a single company are used in the analysis. The program log clearly documents the date, time, and the reasons for changes to the programs. In this study the relationships among the variables of business requirements change, software complexity, program size and the error rate in each phase of software development life cycle are tested. Interpretations of the hypotheses testing are provided as well. The data shows that analysis error and design error occur more often than programming error. Measurement criteria need to be developed at each stage of the software development cycle, especially in the early stage. The quality and reliability of software can be improved continuously. The findings from this study suggest that it is imperative to develop an adaptive system that can cope with the changes to the business environment. Further, management needs to focus on processes that improve the quality of the system design stage.
Hackman and Oldham's Job Characteristic Model was applied to study of perceptions community music school faculty hold towards their job. The research questions addressed core job characteristics of skill variety, task identity, task significance, autonomy, and feedback, critical psychological states (experienced meaningfulness, experienced responsibility, and knowledge of results); personal and work outcomes of satisfaction and motivation; need for professional growth. The results were compared to the national norms for nine different job families provided by Oldham, Hackman, and Stepina. Thirty-three schools, all members of the National Guild of Community Schools of the Arts, located in every geographical region of the United States, yielded 437 faculty responses (64% return rate). Of the core job characteristics, dealing with others and autonomy received the highest ratings; feedback and task significance received the lowest ratings. Of the psychological states, experienced responsibility yielded the highest rating and experienced meaningfulness yielded the lowest ratings. Of the personal/work outcomes, personal development and colleague relations received the highest ratings; pay satisfaction and overall general satisfaction received the lowest ratings. A comparison to the professional job family norms, using a one-sample ttest, found significant differences in 16 out of the 18 variables measured by the Job Characteristic Model. Strong positive feelings for growth combined with less than strong feelings for the core job dimensions yielded a low motivating potential score of 96.18.
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.
Learning communities have emerged as an efficient and effective paradigm for improving undergraduate education, especially for entering freshmen. The academy has become increasingly interested in learning outcomes and student retention, especially as they are related to the assessment of various approaches to educating the whole student. Learning community pedagogy has developed through rigorous research. However, little is known about the impact of this pedagogy upon college students' cognitive development and writing aptitude. Cognitive development theory has been most significantly influenced by the work of William G. Perry, Jr. Though no theory exists which would address the stages of writing development in university students, many composition theorists suggest a correlation between cognitive development and writing aptitude. This study measured cognitive development and writing aptitude in learning community students and non-learning community students, matching them for SAT scores, high school grade point averages, gender, and ethnicity. The research questions of interest were: 1) How does participation in a learning community affect students' cognitive development; and 2) How does participation in a learning community affect students' writing aptitude? The participants were pre- and post-assessed for cognitive development, using the Measure of Intellectual Development (MID). Additionally, participants were preand post-assessed for writing aptitude, using a diagnostic essay and exit exam. Results of this study indicate no statistically significant differences in cognitive development and writing aptitude for learning community students and non-learning community students as measured by the Measure of Intellectual Development (MID) and the diagnostic essay and exit exam. These findings may have been influenced by the small sample size. It is suggested that this research be replicated, ensuring a larger sample size, to determine the efficacy of this pedagogy on these variable sets.
Psychopaths constitute only an estimated 1% of the population, yet they are responsible for a disproportionately large number of violent and nonviolent crimes. The literature addressing this syndrome among male offenders is quite extensive. In contrast, psychopathy and its underlying factor structure remains understudied among female offenders. Research has suggested marked gender differences in the prevalence, clinical characteristics, and underlying dimensions of psychopathy. This study examined the dimensions of psychopathy in a female offender sample. The Psychopathy Checklist-Revised and the Self Report Psychopathy-II (SRP-II) were administered to 119 female inmates at Tarrant County Jail in Fort Worth, TX. Confirmatory factor analyses of the Psychopathy Checklist-Revised (PCL-R) did not support the use of the traditional two factor male model or a recently proposed two- factor female model. This thesis also addressed females' self-appraisal of PCL-R Factor 1 characteristics as well as the usefulness of the self-administered Self-Report Psychopathy-II as a screen for psychopathy.
The purpose of this research was to study the attitudes of Korean and American early childhood educators concerning gifted children and programs aimed specifically at meeting their needs. The study examined general attitudes towards giftedness and gifted education programs and factors that might affect those attitudes. The study also examined desirable environments for young gifted children. Twenty-item questionnaires were developed and logically divided into six sections (identification, teacher environment, classroom environment, parent environment, educational rights, and program). A systematic process of development, analysis, and refinement of the questionnaire was done. The questionnaires were given randomly to American educators attending the 1996 National Association for the Education of Young Children (NAEYC) conference. A random Korean sample included early childhood educators listed in the Korean Association for Early Childhood Education Directory (1995-1996) and the Korean Association for Child Care Directory (1995-1996). All subjects were members of one of three groups: (a) teacher educators, (b) teachers, and (c) administrators/directors. The surveys found agreement between Korean and American early childhood educators on the importance of knowing the strengths of individual gifted children, the need to stimulate higher order thinking skills, the rights of gifted children to an appropriate education, a perception of more work for the teacher to add these options, and a feeling that gifted programs would be difficult because of the large number of children in classes. The teachers also agreed that it is not difficult to assess or identify gifted preschoolers and having programs for the gifted is not elitist, but that parents should have the main responsibility for meeting the needs of gifted preschoolers and that many gifted strategies are good for all children.
Borel determinacy states that if G(T;X) is a game and X is Borel, then G(T;X) is determined. Proved by Martin in 1975, Borel determinacy is a theorem of ZFC set theory, and is, in fact, the best determinacy result in ZFC. However, the proof uses sets of high set theoretic type (N1 many power sets of ω). Friedman proved in 1971 that these sets are necessary by showing that the Axiom of Replacement is necessary for any proof of Borel Determinacy. To prove this, Friedman produces a model of ZC and a Borel set of Turing degrees that neither contains nor omits a cone; so by another theorem of Martin, Borel Determinacy is not a theorem of ZC. This paper contains three main sections: Martin's proof of Borel Determinacy; a simpler example of Friedman's result, namely, (in ZFC) a coanalytic set of Turing degrees that neither contains nor omits a cone; and finally, the Friedman result.
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.
This study examined the career paths of women administrators serving as chief academic officers in Christian colleges and universities which belong to the Council for Christian Colleges and Universities (CCCU). The CCCU is a professional association of evangelical Christian institutions dedicated to integrating faith and learning. The exploration included each administrator's demographic information; her early, adolescent, college, and graduate school experiences; early vocational experiences; the effect of marriage and motherhood on her career; critical factors she identified as important in achieving her current position; and the importance of spiritual convictions or Christian faith in career decision making. Sixteen of the eighteen identified women holding the rank of chief academic officer agreed to participate in the study. The typical woman administrator was 50, married, and the mother of one or more children. She most likely had received her education in the humanities, with the terminal degree of choice being a Ph.D. She had served at her current institution for more than five years, but in her current administrative position for less than five. As an adolescent she excelled in the humanities, less so in math and science, and was involved in many extracurricular activities, including music endeavors, leadership, and her local church. She had received the most encouragement from her mother, although both parents expected her to do her best in school. For post secondary education, she had benefited from a mentor, had excelled easily, and had taken no time off between her bachelor's and master's degrees or between her master's or doctoral degrees. Although she had aspired to teach and received most of her early vocational experience in the professoriate, she had not aspired to be an administrator. As an adult, she had married in her 20's and had children before the age of 30. She had an unusually supportive …
Although music publishing in Italy was on the decline around the turn of the seventeenth century, Venice emerged as one of the most prolific publishing centers of secular song in Italy throughout the first three decades of the 1600s. Many Venetian song collections were printed with alfabeto, a chordal tablature designed to facilitate even the most untrained of musicians with the necessary tools for accompanying singers on the fashionable five-course Spanish guitar. Carlo Milanuzzi's Quarto Scherzo (1624) stands out among its contemporary Venetian song collections with alfabeto as an anthology of Venetian secular songs, including compositions by Miniscalchi, Berti, and Claudio and Francesco Monteverdi. Issues surrounding its publication, instrumentation, and musical and poetic style not only contribute to the understanding of Venetian Baroque monody, but also help to construe a repertory of vocal music with defining characteristics usually associated with popular music of the 19th, 20th, and 21st centuries.
This study scrutinizes the drug-terrorism nexus critically with intent to conceive possible remedies for the problem. The vast turnover of the global illicit drug industry constitutes the largest portion of organized crime enterprises' income. Different circles have argued that these enterprises are not the sole actors of the drug business, but terrorist groups, whose ultimate aim is a political change rather than financial strength, also profit from the “business.” The controversial nature of the problem fuelled heated debates and requires an in depth and impartial analysis, which was the main subject of the current study. At the first stage, three different cases, the PKK, the LTTE, and the SL, were studied either to prove or deny the alleged phenomenon. The sampled groups' ideology, structure, and operations helped understand the motives pushing the organizations into the ‘business.' Subsequently, several recommendations capturing vital issues both in countering terrorism and breaking terrorism-drugs link were spelled out.
Advertising, which is an important sales tool for brands to the masses, may produce lasting impressions of a company and its products. These impressions rely on a consistent message over time to maintain a brand's image. This study examines how Ralph Lauren's advertising images have changed from a country club lifestyle image to urban/hip. In addition, the study examines the increased use of nudity and sexual imagery in Lauren's advertising. The findings were obtained by content analyzing all Ralph Lauren advertisements appearing in Gentlemen's Quarterly magazine from 1980 to 2000 (N=283). The study finds that Ralph Lauren lifestyle images have become more urban/hip, and that Lauren's advertising is utilizing more nudity, sexual interaction, and homoerotic imagery. By examining Ralph Lauren's shifting brand image via its advertising, this study contributes to a greater understanding of the connection between advertising and a company's brand image.
The purpose of this study was to analyze the characteristics of teacher directed modeling evidenced in the practices of three experienced high school choral directors. Research questions were: 1. What modeling activities were exhibited in each teacher's rehearsals? 2. When viewing a 45-minute composite tape of each teacher's instructional activities representative of all rehearsals, what instructional behaviors did each choral director recognize and identify as modeling? 3. What instructional episodes on the composite tape not identified by the teachers contained elements of modeling? 4. What other episodes from the remainder of each choral director's rehearsal practice contributed to an understanding of modeling? Videotapes of three high school choral directors were recorded over the course of one semester. Excerpts from rehearsals were combined to form a 45-minute composite tape of each choral director. A text transcription was made of the composite tape. Participant directors viewed their tape and identified instructional episodes that they recognized as examples of modeling. Identifications were analyzed, and descriptive categories of modeling behaviors were established. Modeling was found to be a teacher generated or delegated act of demonstration. Demonstrations were musical or non-musical and belonging to either of three distinct categories: audible, visible, or process modeling. Subdivisions of each category were found further describing modeling in the high school choral rehearsal. In addition, types of modeling were noted in increasing cognitive complexity required on the part of students beginning with simple imitation and concluding with models as tools for musical problem solving. Research is recommended on a larger sample of participants, including junior high/middle school directors to confirm categories and levels and to develop an observation tool based on results for describing, assessing, and modifying instructional techniques of practicing and pre-service music educators.
An aspartate transcarbamoylase (ATCase) gene from Bordetella pertussis was amplified by PCR and ligated into pT-ADV for expression in Escherichia coli. This particular ATCase (pyrB) was an inactive gene found adjacent to an inactive dihydroorotase (DHOase) gene (pyrC'). This experiment was undertaken to determine whether this pyrB gene was capable of expression alone or if it was capable of expression only when cotransformed with a functional pyrC'. When transformed into E. coli TB2 pyrB-, the gene did not produce any ATCase activity. The gene was then co-transformed into E. coli TB2 pyrB- along with a plasmid containing the pyrC' gene from Pseudomonas aeruginosa and assayed for ATCase activity. Negative results were again recorded.
In order to assess the extent and quality of special education services in charter schools in north Texas, the researcher examined data submitted to Texa Public Education Information Management System (PEIMS), and conducted qualitative interviews with selected charter school administrators. Five cornerstones of the Individuals with Disabilities Education Act (IDEA): zero reject, individualized education program (IEP), appropriate assessment, free appropriate public education (FAPE), and least restrictive environment (LRE), were utilized in the assessment of quality. Levels of expertise in federal disability law and fiscal barriers were explored, as well.
This study involved non-experimental research to identify alumni perceptions of the strengths and weaknesses of the Doctor of Ministry degree program at Dallas Theological Seminary. An international survey was conducted to collect data from 165 Doctor of Ministry degree holders from Dallas Theological Seminary; 131 usable questionnaires were returned. A response rate of 79.4 percent was achieved. The intent of the study was to ascertain (a) the extent to which D.Min. alumni perceive that the objectives and goals of Doctor of Ministry programs at Dallas Theological Seminary are being met, (b) alumni-perceived strengths of Doctor of Ministry programs at Dallas Theological Seminary, (c) alumni-perceived weaknesses of Doctor of Ministry programs at Dallas Theological Seminary, (d) compare the findings of this case study assessment with a 1987 national study of Doctor of Ministry programs, and (e) make recommendations for the improvement of D. Min programs at Dallas Theological Seminary. The pattern that emerged from the data indicates that the D.Min. alumni believe objectives and goals of the Doctor of Ministry program at Dallas Theological Seminary are being met. In the opinion of the alumni, Doctor of Ministry programs at Dallas Theological Seminary has its strengths. The overall opinion of the D.Min. faculty and curriculum are strong indicators of its strength. The D.Min. program has had a positive impact on the lives of its alumni and on their ministries. In the opinion of the alumni, Doctor of Ministry programs at Dallas Theological Seminary also has its weaknesses. A casual comparison of the findings of this case study assessment with a similar 1987 national study of Doctor of Ministry programs revealed more similarities than differences. The alumni provided a number of suggestions to be implemented into the Doctor of Ministry curriculum, structure, faculty, administration, overall image of the program, its purpose and objectives.
Assuming the axiom of determinacy, we give a new proof of the strong partition relation on ω1. Further, we present a streamlined proof that J<λ+(a) (the ideal of sets which force cof Π α < λ) is generated from J<λ+(a) by adding a singleton. Combining these results with a polarized partition relation on ω1
Historians often emphasize the physical features of battleterrain, weaponry, troop formations, earthworks, etc.in assessments of Civil War combat. Most scholars agree that these external combat conditions strongly influenced battle performance. Other historians accentuate the ways in which the mental stresses of soldiering affected combat performance. These scholars tend to agree that fighting effectiveness was influenced by such non-physical combat conditions as unit cohesion, leadership, morale, and emotional stress. Few authors argue that combat's mental influences were more significant in determining success or failure than the physical features of the battlefield. Statistical analysis of the 465 tactical engagements fought by twenty-seven Federal regiments in the First Division of the Army of the Potomac's Second Corps throughout the American Civil War suggests that the mental aspects of battle affected fighting efficiency at least as muchand probably more thancombat's physical characteristics. In other words, the soldiers' attitudes, opinions, and emotions had a somewhat stronger impact on combat performance than their actions, positions, and weaponry.
The purpose of this study is: to explore and analyze the Communication Assistance for Law Enforcement Act of 1994 (CALEA), to identify problems related to CALEA, to identify solutions devised by other countries to overcome problems similar to CALEA's, and to propose feasible solutions to CALEA problems.
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 …
This study compared traditional, A/B and accelerated block scheduling and its effects on student achievement and attendance by comparing the differences in student outcomes observed before and after the adoption of block/accelerated block schedules. The independent variable was the use of time in a block-scheduling model. The dependent variables were student outcomes measured by nine indicators based on the Academic Excellence Indicator System in Texas: student attendance, graduation rate, dropout rate, percentage of students taking advanced courses, percentage of students passing all Exit-level Texas Assessment of Academic Skills tests, percentage of students taking College Admissions Tests, mean SAT total score of those students who took the SAT, mean ACT total score of those students who took the ACT, and percentage of students who are at or above criterion on the SAT or ACT of those students taking the SAT or ACT. Data from archival files from the Texas Education Agency's Academic Excellence Indicator System for each respective year of the eight-year longitudinal study was collected. Scheduling models (traditional, alternating block and accelerated block) were investigated. The sample was drawn from the student population of a large urban school district in north central Texas, a district serving approximately 77,000 students. The district has twelve regular high schools serving students in grades nine through twelve. All twelve regular high schools were included in this study. The indicators were analyzed using SPSS multivariate and univariate analysis to compare the means, regression line slopes, and regression line intercepts for each type of schedule: traditional only, traditional prior to A/B block change, traditional prior to accelerated block change, A/B block, and accelerated block. The regression line, slopes, and intercepts were based on separate regression analysis where a school year was used to predict the AEIS indicators for each type of schedule. With the exception of …
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%).
Media sociologists have produced much research on the systems of production of media content. Photojournalism, however, largely has been ignored in these studies. This paper presents the findings of an ethnographic study of work routines and photojournalism practices at three newspapers. The study explored the extent to which routines and practices are affected by professional norms and values and organizational needs and beliefs. The study also explored how these factors influence the content and aesthetic qualities of newspaper photographs. Findings suggest that photo editors and photojournalists operate under many of the same constraints as other media workers. The findings also show that photojournalists are socialized to newspapers. expectations by fellow photographers and photo editors. To gauge professional accomplishments, photojournalists rely on peers, professional organizations and competitions.
The purpose of the following study was to evaluate sexual trauma and the effects on women veteran's quality of life ratings and current and past coping strategies. Participants were screened for sexual trauma history and divided into five mutually exclusive categories: 1)childhood sexual trauma, 2)civilian adult sexual trauma, 3)military sexual trauma, 4)multiple sexual trauma, and 5)no sexual trauma. Results of the study were mixed, retaining some hypotheses and rejecting others. Results regarding differences in QOL for the sexual trauma groups were rejected, as none of the QOL analyses were significant. Issues of small effect size for the QOL measure and low power to detect differences are discussed as limitations in the current study. Several significant findings were detected in the coping analyses. As predicted, the no trauma group was found to use significantly more approach coping strategies than the sexual trauma group for the past problem. Additionally, the sexual trauma group used significantly more avoidant coping techniques for past problem than the no trauma group. No between group differences were detected for sexual trauma type, however, several significant differences emerged in the comparisons of the multiple sexual trauma and military sexual trauma group's past coping compared to the no sexual trauma group's coping strategies. For past coping, the no trauma group used more approach strategies than the military or multiple trauma group. Past and current significant CRI subscale differences were also detected. Results regarding the relationship between QOL and CRI were rejected, as the two scales were not found to correlate significantly. Trauma history and avoidant coping were also nonsignificant predictors for General Life Satisfaction on the QOL measure. Additional exploratory analyses are presented as well as implications for research, theory and clinical practice.
Over the last 30 years, the juvenile justice system and juvenile correctional ideology shifted to become more punitive in nature. However, studies examining this shift are lacking in the literature. The present study will attempt to assess what correctional ideology, rehabilitative or punitive, is dominant within juvenile corrections by conducting a national survey to juvenile facility directors. This study will be based on prior literature, most of which has focused upon line staff in an adult correctional setting. From this prior literature, more specifically from the work of Cullen et al. (1989), scales will be created to determine the correctional orientation of the key administrators in juvenile facilities. This will allow us to assess whether the correctional ideology driving the juvenile system has in fact become punitive. The findings from this study have the opportunity to alter the current status quo in juvenile corrections.
I assessed fish community data collected by the Oklahoma Conservation Commission from 82 minimally impaired wadeable reference streams in eastern Oklahoma to determine whether existing aquatic ecoregions provide the best framework for spatial classification for the development of biological assessment methods and biocriteria. I used indirect ordination and classification to identify groups of sites that support similar fish communities. Although correspondence was observed between fish assemblages and three montane ecoregions, the classification system must be refined and expanded to include major drainage basins and physical habitat attributes for some areas to adequately partition variance in key measures of biological integrity. Results from canonical correspondence analysis indicated that substrate size and habitat type were the primary physical habitat variables that influenced the fish species composition and community structure.
This study discussed the issue of computer crime as it relates to the criminal justice system, specifically law enforcement. The information was gathered through several books, academic journals, governmental documents, and the Internet. First, the nature and forms of computer crime, Internet crime, and cyber terrorism were analyzed. Next, law enforcement responses were discussed. International aspects of the problem were separately pointed out. Further, detection and investigation of computer crime were examined. Problems related to the each component of the criminal justice system (law enforcement, investigators, prosecutors, and judges) were described. Specific solutions to these problems were offered. In addition, computer crime handling procedures were presented. Results indicate that computer crime will increase in the 21st century, and this problem cannot be controlled by traditional methods alone. Using new technology as preventive measures, and increasing awareness and security conscious culture will prevent the problem in the long run.
his study compares ethnic, age, and gender differences concerning attitudes and behaviors toward death, dying, and bereavement among Caucasian, African, Hispanic, and Asian American adult participants in north Texas with the results of a 1976 study by Kalish and Reynolds on death attitudes and behaviors of Caucasian, African, Mexican, and Japanese American adult participants in Los Angeles, California. A modified version of Kalish and Reynolds' study questionnaire was administered to 526 respondents (164 Caucasian, 100 African, 205 Hispanic, and 57 Asian Americans) recruited from community and church groups. Findings of this study were compared with those of Kalish and Reynolds in specific areas, including experience with death, attitudes toward one's own death, dying, and afterlife, and attitudes toward the dying, death, or grief of someone else. Data was analyzed employing the same statistical tools as those used by Kalish and Reynolds, i.e., chi square calculations, frequencies, percentages, averages, and analyses of variance. As compared with the earlier study, results indicated that this study's participants were less likely to have known as many persons who had died recently or to state they would try very hard to control grief emotions in public. Present study participants were more likely to have visited dying persons, to want to be informed if they were dying and believe that others should be informed when dying, to prefer to die at home, to have made arrangements to donate their bodies or body parts to medicine, to have seriously talked with others about their future deaths, to consider the appropriateness of mourning practices and the comparative tragedy of age of death from a relative standpoint, and to want to spend the final six months of their lives showing concern for others. Between study differences were found in ethnic group, age group, and gender group comparisons. Within study …
This study described and analyzed the development and implementation of an advisory program at one urban middle school. Development of the advisory program began during the 1997-98 school year. The implementation of the program was examined during the 1998-99 and 1999-2000 school years. This school site was chosen because of the in-depth research and planning of the program beyond the typical amount performed by many schools, and the wide-scale staff participation utilized in the program's development. In order to follow the processes of development and implementation, several models of change, innovation, and organizational analysis were used to provide focus for analysis of events that occurred during the three years of the program examined in this study. Data was collected in multiple manners. A complete review of school documents concerning the advisory program was performed, and over 50 percent of the faculty were interviewed through individual and team interviews. The findings of this study include various elements concerning the development and implementation of the advisory program. Data was collected and analyzed in three main categories including a) driving and resisting factors for beginning and implementing the program, b) processes used to plan, maintain and develop the program, and c) the periods in which the program became stable. Additional considerations were examined including the evaluation of the program, future possibilities for implementation, and staff roles in the program. Recommendations of the study include: limiting the focus of the advisory program; maintaining consistent goals; starting with a limited program; securing high staff participation; providing extensive time for planning; maintaining a high level of monitoring by administration and staff leaders; providing in-depth training; and, insuring that open lines of communication exist.
The Council for Accreditation of Counseling and Related Education Programs (CACREP) is the accrediting body for the field of counselor education. Since the inception of the standards, several individuals have published journal articles reviewing the strengths and weaknesses of CACREP accreditation. The purpose of this study was to do a preliminary survey of the opinions of individuals within CACREP accredited programs to discover the effects of accreditation on programs. The survey of opinions from respondent CACREP accredited programs indicated interesting results. The eleven frequently held beliefs about improvements after accreditation was substantiated by the number, the percentage, and the Chi Square results from respondent programs. Therefore, after CACREP accreditation, most programs reported the opinion that: students have higher grade point averages and test scores; students are younger, learn better, and receive more employment opportunities; a higher percentage of students pass the licensed professional counselor examination; average scores are higher on the nationally certified counselor examination; programs receive more applicants and faculty is more professionally active, publishes more, and presents more. The second part of the survey indicated that a large percentage of respondent programs offer courses beyond the CACREP core curriculum experiences (91%) and that a variety of courses are offered (78 courses). In addition, 91 respondent programs indicated that courses are required beyond the CACREP core curriculum experiences and that a variety of courses are required (29 courses). Three primary limitations exist in this study. First, the eleven frequently held beliefs were marked by the opinion of one faculty member for each program. Second, the number of blanks for each item was frequently close to or sometimes exceeded the number of respondents who marked the after CACREP column. Third, the survey data collected on courses that were offered by programs beyond the core were based upon memory and/or opinion …
The Depressive Experiences Questionnaire Dependency scale has been used extensively by researchers to measure a personality style vulnerable to depression. However, subsequent studies have demonstrated that the DEQ-Dependency is composed of two distinct forms of dependency, "Connectedness" and "Neediness", which may have different implications for mental health. While Connectedness may represent a more mature form of dependency than Neediness, it may not represent an entirely "healthy" form of relatedness as previously suggested. Although these scales are being used in current research, it is not yet clear what they represent. One goal of the present study was to further examine the construct validity of Connectedness and Neediness in order to differentiate these constructs. Gender, self-efficacy, relationship quality, and interpersonal behavior were chosen because of their proposed significance in differentiating forms of dependency. 265 undergraduates completed the DEQ, Beck Depression Inventory (BDI), the Mutual Psychological Development Questionnaire (MPDQ), and the Inventory of Interpersonal Problems (IIP). Overall, results supported the importance of distinguishing between these two factors of dependency. Neediness was associated with more maladaptive correlates for both genders. The picture is more complex for Connectedness, however, and it appears that Connectedness is less healthy for women than for men.
The eighteenth century saw many innovations in political culture including the rise of the public sphere where political ideas were freely and openly discussed and criticized. The new public sphere arose within the institutions of private life such as the Republic of Letters and salons, so the modes of behavior in private life were important influences on the new political culture of the public sphere. By studying the lives and careers of Richard Price and the Marquis de Condorcet, I examine the role that the private institution of friendship played in the new political culture of the late Enlightenment. During the 1780s, friendship became an important political symbol that represented the enlightened ideals of equality, reciprocity, liberty, and humanitarianism.
Resources are said to be fragmented in the network when they are available in non-contiguous blocks, and calls are dropped as they may not end sufficient resources. Hence, available resources may remain unutilized. In this thesis, the effect of resource fragmentation (RF) on RSVP-controlled networks was studied and new algorithms were proposed to reduce the effect of RF. In order to minimize the effect of RF, resources in the network are dynamically redistributed on different paths to make them available in contiguous blocks. Extra protocol messages are introduced to facilitate resource redistribution in the network. The Dynamic Resource Redistribution (DRR) algorithm when used in conjunction with RSVP, not only increased the number of calls accommodated into the network but also increased the overall resource utilization of the network. Issues such as how many resources need to be redistributed and of which call(s), and how these choices affect the redistribution process were investigated. Further, various simulation experiments were conducted to study the performance of the DRR algorithm on different network topologies with varying traffic characteristics.
The purpose of this study is to develop an e-government readiness model and to test this model. Consistent with this model several instruments, IS assessment (ISA), IT governance (ITG), and Organization-IS alignment (IS-ALIGN) are examined for their ability to measure the readiness of one organization for e-government and to test the instruments fit in the proposed e-government model. The ISA instrument used is the result of adapting and combining the IS-SERVQUAL instrument proposed by Van Dyke, Kappelman, and Pybutok (1997), and the IS-SUCCESS instrument developed by Kappelman and Chong (2001) for the City of Denton (COD) project at UNT. The IS Success Model was first proposed by DeLone and McLean (1992), but they did not validate this model. The ITG instrument was based on the goals of the COD project for IT governance and was developed by Sanchez and Kappelman (2001) from UNT. The ISALIGN instrument was also developed by Sanchez and Kappelman (2001) for the COD project. It is an instrument based on the Malcolm Baldrige National Quality Award (MBNQA) that measures how effectively a government organization utilizes IT to support its various objectives. The EGOV instrument was adapted from the study of the Action-Audience Model developed by Koh and Balthazrd (1997) to measure how well a government organization is prepared to usher in e-government in terms of various success factors at planning, system and data levels. An on-line survey was conducted with employees of the City of Denton, Texas. An invitation letter to participate in the survey was sent to the 1100 employees of the City of Denton via email, 339 responses were received, yielding a response rate of 31%. About 168 responses were discarded because they were incomplete and had the missing values, leaving 171 usable surveys, for a usable set of responses that had a response …
As a result of the reauthorization of the Individuals with Disabilities Education Act of 1997, schools must now consider positive behavioral interventions and strategies to address problem behavior of students with Emotional/Behavioral Disorders (E/BD). Given the poor behavioral, academic, and social outcomes for these students, there is a compelling need to identify effective, proactive interventions. Current literature has well established the ineffectiveness of traditional, punitive, and consequence-laden strategies to deal with behaviors. Research has shown the manipulation of antecedent stimuli, in the form of curricular adaptations, can provide a positive, proactive means of managing behavior. Specifically, curriculum modifications, based on student interest, are proposed as a positive, proactive strategy used to manipulate antecedent stimuli to improve the behavior of students with E/BD. The purpose of this study was to investigate the manipulation of antecedent stimuli through the implementation of individualized, curricular adaptations, based on student interest, to reduce the problem behavior of students exhibiting disruptive behaviors. A second purpose was to explore the effect of those adaptations on the behavior motivation of students with E/BD. In this study, curriculum modifications based on student interest were used to reduce disruptive behavior, increase desirable behavior, and effect change in the motivation for problem behavior among four elementary school boys with E/BD. Use of an ABAB reversal design, including interval data collection, and the use of a behavior rating scale and a motivation assessment scale were used to establish baseline data and determine effectiveness of the intervention. Results indicate that each student demonstrated a reduction in disruptive behavior, an increase in desirable behavior, and changes in motivation for behavior.
The purpose of this study was to determine if psychological type, economic status, and minority classification had an effect on the pass/fail rates of vocational nursing students. The rationale for conducting this study was based on the need for the institution to maintain program viability and successfully retain students. The personality types of vocational nursing students were measured using the Myers-Briggs Type Indicator. Measures of economic status and minority classification were obtained through subject self-report. Students enrolled in a vocational nursing program at a small North Texas community college were studied. The Chi-square Test of Independence with a 2 x 2 design was employed. Findings indicated that there was a statistically significant relationship between the pass/fail rates of thinkers versus feelers in the vocational nursing classroom. Findings did not indicate a statistically significant relationship between the pass/fail rates of extraverts versus introverts; sensers versus intuitives; or judgers versus perceivers in the vocational nursing classroom. Findings also suggested that there were no significant relationships between the pass/fail rates of individuals with poverty versus non-poverty economic statuses, nor between individuals with minority versus non-minority classifications. Based on this study, vocational nursing students psychologically typed as thinkers, may have lower passing rates in the vocational nursing classroom setting.
Using an experimental-comparison group design, data were collected at the beginning and end of a semester to assess the effect of a human sexuality course on students' sexual knowledge, sexual attitude, and sexual behaviors. Data analysis by t-tests showed statistical differences between the experimental and comparison group only on sexual knowledge scores ( p < .001), with the experimental group scoring higher. T-tests showed statistical difference between males and females in sexual attitude (p< .001) and sexual behavior (p< .001) with women scoring higher than men in the experimental group, and also when experimental and control groups were combined. Although not statistically significant, women scored higher in sexual knowledge than males.
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 face of the American workforce is changing. As more women and minorities enter the workplace and globalization continues, workers must work with. interact with, and sell to people who are different from themselves. Workers bring their cultures, attitudes, and modes of operation with them. To address the issue of being productive in a diversified environment, corporations have implemented diversity training programs. For the purpose of this study, diversity was defined as gender differences. This research examined the effects of diversity training on increasing the awareness and understanding of gender differences in the workplace. The experimental design of the study was a pretest posttest involving two groups in a large corporation who received different forms of training to address gender differences. One group received its training in the traditional manner currently used in the corporation. The second group participated in enhanced training targeted to include multiple learning styles and focused on why this effort was important to the individuals as well as the corporation. A true-false test based on gender differences was given prior to the training to account for individual differences and to establish the means for the groups. The same test was given following the training to determine the effectiveness of the training. The statistical procedure used in this study was an analysis of covariance (ANCOVA) in order to determine whether there was a significant difference between the mean scores of the two groups. A level of significance of .05 was specified. Calculations were done using the computer program SPSS version 9.0. The data yielded a statistically significant difference between the employees who received the enhanced training and the employees who received the standard training on knowledge of gender differences in the workplace.
The effects of graduated exposure, modeling and contingent social attention on tolerance to skincare products were evaluated with two boys with autism who displayed tactile defensiveness. Upon each presentation step of skincare products the number of positive and negative responses and successful step completion were measured. Procedures included modeling, presenting graduated opportunities, and providing social attention for step completion. Step advancement occurred if a child engaged in a step independently, without excessive refusals. A changing criterion design and a multiple baseline were employed to evaluate effects of this treatment package. Children demonstrated more positive and fewer negative responses as they completed the graduated steps. Effects maintained in follow-up observations.
This study examines the effects of training in two yoked learning channels (hearsee/say and hearsee/write) on the acquisition, generalization and retention of learning. Four fifth-grade participants were taught the lower-case letters of the Greek alphabet. Twelve letters were taught in the hearsee/say channel and twelve letters taught in the hearsee/write channel for equal amounts of time. The see/say channel reached higher frequencies at the end of training and showed higher acquisition celerations than the see/write channel. However, the see/write channel showed higher accuracy and retention than the see/say channel. The see/write channel also showed greater generalization across learning channels including the see/say, think/say, think/write and see-name/draw-symbol.
This study analyzed the effects of restricting the response space and selfevaluation on students' handwriting quality in two beginning handwriters and two experienced handwriters. Students executed letters with and without using a transparent overlay, in a multiple-baseline-across-letters design. The use of the transparent overlay included drawing letters in a space restricted by the transparency; overlaying a model letter on top of the written letter and; evaluating if the two letters matched. Letter quality immediately improved when overlays were used, and handwriting quality maintained when the writing response was not restricted by the overlay transparency. Prompting and feedback were delivered contingent on on-task behavior. Analysis was based on three different measurement systems.
The purpose of this study was to investigate the effectiveness of teaching reading through discussion of text structures on students' reading comprehension. The design of the study was a Pretest-Posttest Control-Group Design. One hundred twenty-six sophomore and senior Thai college students majoring in English and attending afternoon English classes participated in the 10-week study and were randomly assigned to an experimental group and a control group. The experimental group received reading instruction in the characteristics of narrative and expository text structures and how to discuss the details of story by applying knowledge of text structures. The control group, on the other hand, read each story silently by themselves and answered comprehension questions. The posttest means of the two groups were compared, and a t test was used to test the significance difference of the means. The results did not reveal any differences between the means. The short time of the intervention may be a crucial factor that made the two strategies yield the same effects. However, the survey responses showed the participants liked reading through discussion of text structures more than reading by themselves.
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.
