- The use of notated and aural exercises as pedagogical procedures intended to develop harmonic accuracy among beginning jazz improvisers
- This study compared the effects from the use of aural and notated exercises as pedagogical procedures for teaching harmonic accuracy to beginning jazz improvisation students. The methods of pedagogy were identified from published pedagogic and historical sources, the results of oral and written traditions of jazz pedagogy. The performance objective was produced from a review of the related literature as a recognized and measurable characteristic of jazz improvisation. The purpose of this study was to compare measurements of harmonic accuracy, following the use of notated and aural exercises as experimental procedures of jazz improvisation pedagogy. A lesson plan, materials, curriculum and outline were developed followed by student recruitment and participation. A total of 20 student volunteers participated in the methods of pedagogy (aural or notation). Data collection consisted of a musical background questionnaire and pre and posttest performance recordings. Student recordings were evaluated by six judges using the “experimental performance evaluation measure.” Statistical analyses were conducted, including comparisons of pre to posttest effects between, and among the methods of pedagogy. Although all student participants performed mostly from notated music prior to this study, students who received the aural method of pedagogy produced greater improvement for all measurement items. While the aural method produced no differences between grade level, the notation method produced significantly lower scores for 9th graders compared to 12th graders; no other significant grade level differences were noted. Conclusions were that although many sources of pedagogy do not include aural exercises as the predominate activity, beginning improvisers who have more experience reading music than playing by ear, learn better from aural, than notated exercises.
- An Examination of the Adoption of Preservation Metadata in Cultural Heritage Institutions: An Exploratory Study Using Diffusion of Innovations Theory
- Digital preservation is a significant challenge for cultural heritage institutions and other repositories of digital information resources. Recognizing the critical role of metadata in any successful digital preservation strategy, the Preservation Metadata Implementation Strategies (PREMIS) has been extremely influential on providing a "core" set of preservation metadata elements that support the digital preservation process. However, there is no evidence, in the form of previous research, as to what factors explain and predict the level of adoption of PREMIS. This research focused on identifying factors that affect the adoption of PREMIS in cultural heritage institutions. This study employed a web-based survey to collect data from 123 participants in 20 country as well as a semi-structured, follow-up telephone interview with a smaller sample of the survey respondents. Roger's diffusion of innovation theory was used as a theoretical framework. The main constructs considered for the study were relative advantage, compatibility, complexity, trialability, observability, and institution readiness. The study yielded both qualitative and quantitative data, and analysis showed that all six factors influence the adoption of PREMIS in varying degrees. Results of a regression analysis of adoption level on the six factors showed a statistically significant relationship. The R2 value for the model was .528, which means that 52.8% of the variance in PREMIS adoption was explained by a combination of the six factors. Considering the complexity of issue, this study has important implications for future research on preservation metadata and provides recommendations for researchers and stakeholders engaged in metadata standards development efforts.
- Social Self-Concept and Positive Illusory Bias in Boys and Girls With and Without Attention-Deficit/Hyperactivity Disorder
- This study examined differences in social self-concept, as measured by the Self-Perception Profile for Children (SPPC), between boys and girls with and without attention-deficit/hyperactivity disorder (ADHD) while controlling for internalizing symptoms. Ninety-six children between the ages of 8 and 13 participated in the study as part of a larger project. Teacher reports of social competence were collected using the Teacher Rating Scale (TRS). The results indicated ADHD children experienced more peer rejection than control children. ADHD girls appeared to be more susceptible to low social self-concept and competence than control children or ADHD boys. Inattentive symptoms were most predictive of teacher reports of competence. Positive illusory bias was not found to serve a protective function in children regardless of ADHD status. The implications of the current study and directions for future research are presented.
- Caregiving style in diverse samples of caregivers.
- With three homogenous caregiver groups (i.e., Alzheimer's caregivers, grandparents raising grandchildren, parents), caregiving styles were explored to determine their reliability and validity, their unique role in predicting caregiver outcomes, and their differences between groups of caregivers. A conceptual framework was adapted to determine the impact of contextual variables, caregiving styles, caregiver appraisal, and mediating variables on caregiving outcomes. A more concise version of the Caregiving Style Scale (CSS) was developed with 49 items yielding an internal consistency coefficient of .74. As expected, three caregiving styles emerged and were positively related to the parallel parenting styles. Across the caregiver samples, there were positive relationships among caregiving style dimensions within the same caregiving style, while those from opposing caregiving styles tended to have negative relationships indicating good convergent and discriminant validity. Authoritative caregiving style dimensions were generally associated with healthier functioning, while authoritarian and permissive caregiving style dimensions were correlated with less healthy functioning. Caregiving style dimensions were among the predictors of several outcome measures, highlighting the importance of their placement in the conceptual framework for caregiver stress and coping. Generally, an unexpected finding was that authoritative caregiving style dimensions tended to predict less adaptive caregiving outcomes, particularly for parents and grandparents, while the impact upon caregiver well-being by authoritarian caregiving style dimensions varied throughout the caregiver groups. Results further indicated that different groups of caregivers tend to take on different caregiving styles, with grandparents and parents tending to differ significantly from Alzheimer's caregivers in their approaches to caregiving.
- Body ideals and weight bias: Does ethnicity make a difference?
- The current study investigates whether there are there ethnic differences between Caucasian, African American, and Hispanic women in (a) weight bias, (b) body ideals, (c) social awareness and internalization of appearance standards and (d) physical activity in relation to these constructs. Participants included 130 Caucasian, 103 African American, and 52 Hispanic undergraduate female students. Participants completed a demographic survey, the Antifat Attitudes Test, the Figure Rating Scale, the Sociocultural Attitudes toward Appearance Questionnaire, and the Multiethnic Identity Measure questionnaire. No significant ethnic group differences in weight bias emerged. Differences were found for participants' perceptions of the culturally ideal female body shape, as well as awareness and internalization. No relationship was found between physical activity and weight bias, body ideals, and appearance standards. Future researchers should use health weight classifications, in addition to ethnicity, to examine weight bias, body ideals, and physical activity.
- Pursuit of Happiness: Struggling to Preserve Status Quo in Revolutionary Era Nova Scotia
Access: Use of this item is restricted to the UNT Community.
Following the Glorious Revolution in 1688, the British North American colonies interpreted Parliament's success in removing arbitrary governmental practices and establishing a balanced government as a victory for local representative government. Within these colonies, merchants secured their influence in local government in order to protect their profits and trade networks. The New England merchants that resettled in Nova Scotia in the 1750s successfully established a local government founded upon their rights as British subjects. The attempt by the British government to centralize the imperial administration in 1763 and the perceived threat of reintroducing arbitrary rule by Parliament was a direct threat to the colonial governmental system. Although Nova Scotia chose loyalism in 1775-1776, this decision did not stem from isolation or a differing political philosophy. In fact, it was their cultural and political similarities that led Nova Scotia and New England to separate paths in 1776. Nova Scotia merchants controlling the Assembly were able to confront and defeat attempts that threatened their influence in local politics and on the local economy. With the threat to their authority defeated and new markets opening for the colony, the Nova Scotia merchant class was able to preserve the status quo in local government.
- Evaluating Quality Standards for Teachers in the Field of Emotional and Behavioral Disorders
- The purpose of this study is to determine quality indicators in the field of emotional and behavioral disorders based on six empirically validated standards outlined by the Council for Exceptional Children. Invitations to participate in the study were disseminated to a randomized selection of members within the Council for Children with Behavioral Disorders. Respondents (N = 199) included teachers (n = 128) and related service personnel (n = 71) who directly and indirectly work with students with emotional and behavioral disorders throughout the United States. A rank order list of the most important knowledge and skills to teachers with regard to demographic characteristics (i.e., types of communities, educational settings, or years of experience) was developed. Additionally, a rank order list was developed to determine which knowledge and skills related service personnel felt should be most important to teachers. Level of agreement was determined between teachers and related service personnel and variances among the rank order lists were examined. Results of the study revealed statistically significant variances in the rank order of knowledge and skills among educational settings of teachers (i.e., self-contained, resource, and general education/inclusion) across the standard of Learning Environments and Social Interactions. Rank orders in two knowledge and skills (i.e., assistive technology and structure) were significant. When rank order was compared between teachers and related service personnel, level of agreement was low within the standards of assessment (58%) and collaboration (63%).
- Evaluating a Doctoral Program in College and University Teaching: A Single Case Study
Access: Use of this item is restricted to the UNT Community.
This study assessed alumni of the College and University Teaching Program at the University of North Texas and how they perceived the training they received. Three hundred sixty alumni holding a college and university teaching degree were surveyed. One hundred forty-two usable questionnaires were returned. A response rate of 39.4 % was achieved. A survey instrument was used to gather alumni perceptions of learning experiences, academics, and professional benefits as a result of earning a doctorate in the major of college and university teaching at the University of North Texas. Alumni were asked their perceptions on the following: 1) the quality of graduate professional education in college and university teaching degree program, 2) whether they thought the goals and objectives of the program were met, and 3) their recommendations regarding the college and university teaching degree program. It is the overall opinion of the alumni that the quality of the graduate education in college and university teaching degree program was high. The majority of alumni indicated that the program should be reinstated and continued and if the program was still available they would recommend it to others.
- A Computation of Partial Isomorphism Rank on Ordinal Structures

- Do As They Say, and As They Do: An Integrated Approach to the Study of Norm Influence on Truth Commission Initiation, 1976-2003
- Truth commissions are bodies established in political transition, and they have the stated purpose of reckoning with human rights abuses committed by members of former regimes. The question driving this research is "Why have truth commissions increased so rapidly in the last 20 years?" This study moves beyond current research, which suggests that particular domestic political circumstances alone determine choice of transitional justice mechanisms. I argue that an international rule of behavior, the transitional restorative norm, has emerged and spread to decision-makers in countries of transition. In support of this notion, I perform a pre-theoretical historical analysis of transitional justice and develop a theory of decision-making in transition-which is later tested with quantitative statistics. This integrated approach allows for increased scientific rigor in the examination of international norms. Ultimately, the study demonstrates an interrelationship between shared ideas and political environments in the determination of domestic policy.
- Interorganizational Relationships: The Effects of Organizational Efficacy on Member Firm Performance
Access: Use of this item is restricted to the UNT Community.
Relationships between the collective actors within interorganizational relationships are a growing area of research in management. Interorganizational networks continue to be a popular mechanism used by organizations to achieve greater performance. Organizations develop competencies to work with other organizations, but the confidence of these organizations to use these strengths for a competitive advantage has yet to be empirically examined. The purpose of this study is to examine organizational efficacy, how competencies may related to that efficacy, and the relationship of efficacy with performance. The goal of this study is to observe the relationship among trust, dependence, information quality, continuous quality improvement, and supplier flexibility with organizational efficacy. In addition, the relationship between organizational efficacy and performance is also observed. There are two primary research questions driving this study. First, what is the relationship between trust, dependence, information quality, continuous quality improvement, supplier flexibility and organizational efficacy? Second, what is the relationship between organizational efficacy and performance? The theories supporting the hypotheses generated from these questions include theories such as social cognitive theory, quality improvement, and path-goal theory. Data collected from the suppliers of a large university support the hypotheses. Regression analysis and structure coefficients were used to analyze the data. Results indicate that both research question one and research question two are supported. In addition, the theoretical model as a whole, which indicates a mediating relationship, was examined and discussed. This study contributes to both academic and practice by examining efficacy in an interorganizational setting. In addition, as organizations better understand the relationship between competencies and confidence, they will better know how to collectively work to achieve greater results with more attention being placed on monitoring the relationship in order to experience more desired outcomes. Limitations of the current study and opportunities for future research are also discussed.
- Language Choice in the ESL and FL Classrooms: Teachers and Students Speak Out
- This paper compares English as a second language (ESL) and foreign language (FL) teachers' and students' perspectives regarding target language (TL) and first language (L1) use in the respective classrooms. Teachers and students were given questionnaires asking their opinions of a rule that restricts students' L1 use. Questionnaires were administered to 46 ESL students, 43 FL students, 14 ESL teachers, and 15 FL teachers in Texas secondary public schools. Results were analyzed using SPSS and R. Results demonstrated an almost statistical difference between perspectives of ESL and FL students regarding TL and L1 use, while teacher results demonstrated no statistical difference between the groups. Students had a more positive perspective of the rule than teachers.
- Bayesian Probabilistic Reasoning Applied to Mathematical Epidemiology for Predictive Spatiotemporal Analysis of Infectious Diseases
- Abstract Probabilistic reasoning under uncertainty suits well to analysis of disease dynamics. The stochastic nature of disease progression is modeled by applying the principles of Bayesian learning. Bayesian learning predicts the disease progression, including prevalence and incidence, for a geographic region and demographic composition. Public health resources, prioritized by the order of risk levels of the population, will efficiently minimize the disease spread and curtail the epidemic at the earliest. A Bayesian network representing the outbreak of influenza and pneumonia in a geographic region is ported to a newer region with different demographic composition. Upon analysis for the newer region, the corresponding prevalence of influenza and pneumonia among the different demographic subgroups is inferred for the newer region. Bayesian reasoning coupled with disease timeline is used to reverse engineer an influenza outbreak for a given geographic and demographic setting. The temporal flow of the epidemic among the different sections of the population is analyzed to identify the corresponding risk levels. In comparison to spread vaccination, prioritizing the limited vaccination resources to the higher risk groups results in relatively lower influenza prevalence. HIV incidence in Texas from 1989-2002 is analyzed using demographic based epidemic curves. Dynamic Bayesian networks are integrated with probability distributions of HIV surveillance data coupled with the census population data to estimate the proportion of HIV incidence among the different demographic subgroups. Demographic based risk analysis lends to observation of varied spectrum of HIV risk among the different demographic subgroups. A methodology using hidden Markov models is introduced that enables to investigate the impact of social behavioral interactions in the incidence and prevalence of infectious diseases. The methodology is presented in the context of simulated disease outbreak data for influenza. Probabilistic reasoning analysis enhances the understanding of disease progression in order to identify the critical points of surveillance, control and prevention. Public health resources, prioritized by the order of risk levels of the population, will efficiently minimize the disease spread and curtail the epidemic at the earliest.
- Immediate and subsequent effects of response blocking on self-injurious behavior.
- Abstract In many institutional settings, blocking, response restriction (e.g., restraint, protective equipment), and re-direction procedures are used extensively as intervention for self-injurious behavior (SIB) and other forms of problem behavior. In the current study, a three component, multiple-schedule analysis was used to examine the immediate and subsequent effects of blocking on SIB that persisted in the absence of social reinforcement contingencies. During the first and third components the participant was in the room, alone, with no social consequences for SIB. During the second component (response restriction) the therapist sat in the room with the participant and blocked occurrences of SIB. Results indicated that, although blocking was effective in decreasing SIB while it was being implemented, subsequent effects were idiosyncratic across participants. Evidence of increased levels of SIB following blocking was observed for some participants.
- Cross-Cultural Adaptability of Texas Dental Hygienists and Dental Hygiene Students: A Preliminary Study
Access: Use of this item is restricted to the UNT Community.
This causal-comparative and correlational study examined cross-cultural adaptability of randomly selected licensed dental hygienists, 1995-2005 graduates, practicing in the state of Texas and first and second-year dental hygiene students attending 5 randomly selected accredited 2 and 4-year dental hygiene schools in the state of Texas. A sample of 289 individuals: 194 enrolled students and 95 licensed dental hygienists, alumni of the 5 schools, completed the 50-item Cross-Cultural Adaptability Inventory (CCAI ®) and a brief demographic survey. The purpose of this study was to determine if statistically significant differences existed among and between licensed dental hygienists and first and second-year dental hygiene students in the state of Texas on a cross-cultural adaptability measure. The study also examined relationships among and between cross-cultural adaptability scores, as measured by the CCAI, and several independent variables. The data were analyzed by using the Statistical Package of Social Sciences (SPSS 12). Eight hypotheses related to group differences and relationships among and between groups and variables were tested. The groups were compared on total CCAI scores using a t-test, and on subscale CCAI scores simultaneously using a descriptive discriminant analysis (DDA). A 3X2 MANOVA was used to compare all groups simultaneously on subscale CCAI scores. The sample was also analyzed for statistically significant differences among 3 levels of ethnicity and total CCAI scores using a one-way analysis of variance (ANOVA). Lastly, various Pearson correlation analyses were conducted to determine relationships among and between the 3 independent variables mentioned above and total and subscale CCAI scores. The results revealed no statistically significant differences among the various groups and CCAI scores. A statistically significant relationship (r = .148) was found between age and 1 of the 4 CCAI subscale scores, flexibility/openness. No other statistically significant relationships were found. The study concluded that number of years for degree, level of practice, ethnicity, and years employed may not play a significant role in enhancing cross-cultural adaptability. Further research needs to be conducted to determine differences and relationships between and among various dental hygiene groups and their cross-cultural adaptability performance.
- An empirical investigation of the salient dimensions of Baby Boomer and Generation Y consumers' health care decision choices.
- The purpose of this research is to empirically investigate consumers' health care decision choices in a dynamic market setting. The unprecedented demands on the U.S. health care system coupled with the mounting controversies surrounding health care reform suggest that consumers' health care decisions warrant empirical research attention. Toward this end, this dissertation empirically explored (1) the characteristics of consumers who possess a willingness to use non-conventional treatments over conventional treatments, (2) the characteristics of consumers who elect self-medication in lieu of health care practitioner-directed medication, and (3) the salient dimensions of consumers' channel choice for the procurement of health care products. Each of these decision choice factors were tested across two U.S. generational segments to assess whether differences existed across Baby Boomers' and Gen Yers' health care decision choices. The conceptual framework for empirical assessment is Bandura's (1986) social cognitive theory. From Bandura's social cognitive theory, a general model of healthcare decision choice is proposed to assess consumers' states of mind, states of being and states of action (decision choice). Results indicate that social cognitive factors (e.g., self-efficacy, objectivism) play an important role in each of the decision domains explored in this dissertation. Moreover, health value was found to be an important moderator between the social cognitive factors and health care decision choices. The predictors of the health care decision choices were found to vary across the Baby Boomers and Generation Yers on several dimensions, confirming the notion that generational differences may be a salient dimension of consumers' health care decision choice. The research offers several implications for practitioners, academicians and policy makers. Both descriptive and normative implications are gleaned from the research findings. Most notably, the results indicate that consumers' social cognitive factors and health value may be mechanisms for managing health care decisions.
- The Undue Burden Standard: The Effects of Planned Parenthood v. Casey (1992) on State Abortion Laws
Access: Use of this item is restricted to the UNT Community.
This thesis examines the effects of the change from strict scrutiny to the undue burden standard in Planned Parenthood v. Casey (1992). A history of abortion in the United States and the various ways in which government regulates it is explored. Particular attention is focused on the role of the federal judiciary in abortion regulation. Theories of judicial decision making are discussed as means to understand the outcome of cases. Several models are tested to determine which, if any, model explains judicial decision making. The effect of the change in standard, as well as an alternate precedent, are examined.
- Stressors, Social Support, and Stress Reactions: A Meta-Analysis
- This study examined, via a meta-analysis, the relations among stressors, social support, and stress reactions. Unexpectedly, small to medium negative, but robust effect sizes were found for the stressors-social support relation. As expected the stressor-stress reaction relation was positive, and the social support-stress reaction relation was negative. Both relations had small to medium effect sizes that ranged from weak to very robust. The direct effect of social support on the stressor-stress reaction was generally supported, whereas the suppressor and mediating models were not supported. Furthermore, the findings were inconclusive for the moderator effect of social support. Non-interpersonal traumas appear different in the stressor-social support and social support-stress reaction relations compared to other trauma types. These findings have important clinical implications.
- The Castrato Sacrifice: Was it Justified?
- One of the greatest mysteries in the history of music is the castrato singers of the Baroque era. Castration has existed for many thousands of years, but for the first time in history, it was used for artistic purposes. Who were these men who seemingly gave up their masculinity for the sake of music? By examining the time period and circumstances in which these musicians lived, an answer may be found. Exploring the economic, social, and political structure of the 17th and 18th centuries may reveal the mindset behind such a strange yet accepted practice. The in-depth study of their lives and careers will help lift the veil of mystery that surrounds them. Was their physical sacrifice a blessing or a curse? Was it worth it?
- Propensity for knowledge sharing: An organizational justice perspective.
Access: Use of this item is restricted to the UNT Community.
Converting individual knowledge into organizational knowledge can be difficult because individuals refuse to share knowledge for a number of different reasons. Creating an atmosphere of fairness plays an important role in the creation of a knowledge-sharing climate. This dissertation proposes that perceptions of organizational justice are crucial building blocks of that environment, leading to knowledge sharing. Data was collected using a field survey of IT managers representing a broad spectrum of the population in terms of organizational size and industry classification. The survey instrument was developed based on the adaptation of previously validated scales in addition to new items where no existing measures were found. Hypotheses regarding the influence of distributional, procedural, and interactional justice on knowledge sharing processes were tested using structural equation modeling techniques. Based on the theory of reasoned action, which states that attitudes and subjective norms are the major determinants of a person's intention, the hypotheses examining the relationship between attitude toward knowledge sharing, subjective norm and the intention to share knowledge were supported. However, results did not support the hypothesis exploring the relationship between the organizational climate and the intention to share knowledge. The results show that all three types of justice constructs are statistically significant antecedents of organizational climate and interactional justice is an antecedent of an attitude toward knowledge sharing. The study attempts to merge streams of research from sociology and organizational behavior by investigating organizational justice and knowledge management. It contributes to theory by the development of the survey instrument, comprised of seven constructs that were developed by incorporating multiple theories to address various aspects of knowledge sharing and provide application to practice and research. It is relevant to IT managers who need to know how to design information systems that are most effective in distributing knowledge throughout organizations.
- The Legacy of Purgatory: The Continuing English Eschatological Controversy
Access: Use of this item is restricted to the UNT Community.
This work examines particular attributes of the purgatorial phenomena from pre-Christian history of the Indo-European world to the Early Modern Period of England. An attempt has been made to identify and concentrate attention upon examples which provide the most significant and penetrating look into this evolution. For example, a portion of this paper attempts to determine just how widespread purgatorial customs were throughout England and the various types of community that supported these beliefs pre and post Reformation. By comparing life before and after the reigns of Henry and Edward a conclusion is reached that reveals the Protestant Reformation in England stripped the laity of a fundamental instrument they needed to support their religiosity and custom. This becomes evident in further years as some of those same customs and rituals that had been considered anathema by Protestants, slowly crept back into the liturgy of the new religion. Strong evidence of this is provided, with a strong emphasis placed upon late seventeenth and early eighteenth century death eulogies, with a section of this paper being devoted to the phenomena of the Sin-Eater.
- An Approach to the Analytical Study of Jung-Sun Park's Choral Work: Arirang Mass
- The significance in Jung-Sun Park's Arirang Mass is the discovery of artistic value in folk song and its applicability to art music. By using fragments of the Arirang folk songs, or by imitating its musical character, composer could create and develop musical characteristics that are recognizably Korean. The work exhibits his remarkable compositional style, which shows a relationship between Korean traditional style and Western style. This analysis demonstrates specific examples of the elements of Korean traditional folksong, such as Sikimsae, Jangdan, Han, and pentatonic scales which are permeated into this mass setting, and how composer uses fragments of the Arirang tune.
- Effects of partner violence and psychological abuse on women's mental health over time.
- This study examined the distinct effects of partner violence and psychological abuse on women's mental health over time. Latent growth modeling was used to examine stability and change over time, evaluating the course and consequences of each form of abuse. The size of women's social support network was examined as a mediator. The sample consisted of 835 African American, Euro-American, and Mexican American low-income women. Participants who completed Waves 1, 2, 3, and 5 were included in the study (n = 585). In general, partner violence decreased over time for all groups, while psychological abuse decreased over time for only Euro-American women. Whereas initial and prolonged exposure to psychological abuse was related to and directly impacted women's mental health, partner violence was only related to initial levels of mental health. Surprisingly, social support was only related to initial violence and distress and had no impact on the rate of change over time. These results have important implications for researchers and health care professionals. First, differences in the pattern of results were found for each ethnic group, reaffirming the notion that counselors and researchers must be sensitive to multicultural concerns in both assessment and intervention. For example, psychological abuse had a greater impact on the mental health of African American and Mexican American women than it did for Euro-American women, suggesting a shift in focus depending on the ethnicity of the client may be warranted. Second, this longitudinal study highlights the importance of future research to considerer individual differences in treating and studying victimized women. Understanding factors that contribute to individual trajectories will help counselors gain insight into the problem and in devising plans to prevent or reduce the occurrence and negative health impact of partner abuse.
- The synthesis and study of poly(N-isopropylacrylamide)/poly(acrylic acid) interpenetrating polymer network nanoparticle hydrogels.
- Homogeneous hydrogels made of an interpenetrating network of poly(N-isopropylacrylamide) (PNIPAm) and poly(acrylic acid) (PAAc) are synthesized by a two-step process; first making PNIPAm hydrogels and then interpenetrating acrylic acid throughout the hydrogel through polymerization. The kinetic growth of the IPN is plotted and an equation is fitted to the data. When diluted to certain concentrations in water, the hydrogels show reversible, inverse thermal gelation at about 34°C. This shows unique application to the medical field, as the transition is just below body temperature. A drug release experiment is performed using high molecular weight dyes, and a phase diagram is created through observation of the purified, concentrated gel at varying concentrations and temperatures.
- Reevaluating twelve-tone music: analytical issues in the second movement of Anton Webern's Quartet for Violin, Clarinet, Tenor-Saxophone and Piano, Op. 22.
- Twelve-tone music illustrates many characteristics relative with those of conventional tonal form, though works are based on a different composition method. The fundamental question of twelve-tone music arises in debate on terminology between tonal and atonal as well as methodology of musical analysis. Certain theorists try to approach twelve-tone music by traditional harmonic views rather than by pitch-class set theory. Conventional harmonic aspects arise from the fact that both tonal and twelve-tone music share similar narrative strategies. This point is explored in examining Anton Webern's Quartet for Violin, Clarinet, Tenor-Saxophone and Piano, Op. 22, which displays connection to tonal music. The present study seeks to examine certain features of the composer's working in pitch materials; i.e., the dispositions of pitch classes and the characteristics of the matching dyads, and thereby to disclose the connection between twelve-tone methods and conventional harmony.
- The Effect of Consumer Shopping Motivations on Online Auction Behaviors: An Investigation of Searching, Bidding, Purchasing, and Selling
- The purposes of the study were to: 1) identify the underlying dimensions of consumer shopping motivations and attitudes toward online auction behaviors; 2) examine the relationships between shopping motivations and online auction behaviors; and 3) examine the relationships between shopping attitudes and online auction behaviors. Students (N = 341) enrolled at the University of North Texas completed self-administered questionnaires measuring shopping motivations, attitudes, online auction behaviors, and demographic characteristics. Using multiple regression analyses to test the hypothesized relationships, shopping motivations and shopping attitudes were significantly related to online auction behaviors. Understanding the relationships is beneficial for companies that seek to retain customers and increase their sales through online auction.
- Correspondence between verbal behavior about reinforcers and performance under schedules of reinforcement.
- Important advancements have been made in the identification of reinforcers over the past decade. The use of preference assessments has become a systematic way to identify preferred events that may function as reinforcers for an individual's behavior. Typically, preference assessments require participants to select stimuli through verbal surveys or engagement with stimuli as preferred or non-preferred. Not all studies go on to directly test the effects of the preferred stimuli, and even fewer studies directly test for the effects of the non- preferred stimuli. The present study systematically identified preferred and non-preferred stimuli in adult human subjects by verbal report and then proceeded to test the effects of both verbally reported preferred and non preferred events on single and concurrent schedules of reinforcement. The results are discussed in terms of contemporary concerns regarding preference and reinforcer assessments.
- Design and Optimization of Components in a 45nm CMOS Phase Locked Loop
Access: Use of this item is restricted to the UNT Community.
A novel scheme of optimizing the individual components of a phase locked loop (PLL) which is used for stable clock generation and synchronization of signals is considered in this work. Verilog-A is used for the high level system design of the main components of the PLL, followed by the individual component wise optimization. The design of experiments (DOE) approach to optimize the analog, 45nm voltage controlled oscillator (VCO) is presented. Also a mixed signal analysis using the analog and digital Verilog behavior of components is studied. Overall a high level system design of a PLL, a systematic optimization of each of its components, and an analog and mixed signal behavioral design approach have been implemented using cadence custom IC design tools.
- Mariama Bâ: un féminisme né à l'intersection de deux cultures.
- Many critics consider Mariama Bâ as a feminist writer, but the reader of her two novels might wonder what characterizes her work as such. Therefore, the aim of each chapter, in order of appearance, is to analyze first the genres, then the elements of African tradition and Western modernity, the characters of both works and the themes of the novels, with the intention of defining the author's feminism, which takes its source in dichotomies, paradoxes and contradictions. In order to expose the author's point of view on the condition of women, it appears important to situate the diegesis in its context. Also, the study is supported by references on the Senegalese culture, by genres, narrative and feminist theories and by critiques on the work itself.
- Chen Yi and Her Choral Music: A Study of the Composer's Ideal of Fusing Chinese Music and Modern Western Choral Traditions
Access: Use of this item is restricted to the UNT Community.
Chen Yi's music is well accepted and recognized nationally and internationally through an increasing number of commissions and performances. Major symphony orchestras, choruses, institutions and companies request her compositions on many occasions in order to increase understanding and exploration of Chinese influences on western classical idioms. This study provides the first detailed discussion of her compositional mastery and her fusion of Chinese music with the language of western choral traditions. Chen Yi's reputation as a prominent orchestral composer does not restrain her passion to apply instrumental techniques and materials to her quality choral compositions. This study focuses on (1) how hardship and various life experiences during the ten-year Cultural Revolution shaped Chen Yi's musical inspirations; (2) how the influences of major musical genres, such as traditional Chinese folksong, jingju, model play, 19th-20th century nationalism, impressionism, and serialism are consolidated in her kaleidoscopic compositional techniques; and (3) the application of Chinese languages, pedagogical concepts, and extra-musical elements, such as Chinese poems, paintings, and calligraphies, revealed in her original, intelligent and resourceful choral creations.
- English language learners: Does summer school make a difference in young children's literacy scores?
Access: Use of this item is restricted to the UNT Community.
Many school districts consider literacy and oral language as a top priority for pre-kindergarten students. In the district under study, pre-kindergarten English language learner (ELL) students are encouraged to attend a special summer school program to increase their oral language ability in English. This study compared three groups of children: ELL students attending summer school v. ELL students not attending summer school v. English speaking students not attending summer school. The students' primary reading inventory scores from the end of pre-kindergarten to the middle of kindergarten in the areas of reading, writing and oral language were compared. As expected, ELLs who attended summer school showed significant growth in oral language development from the beginning of summer school to the end of summer school. While it was hypothesized that ELL students attending summer school would show more improvement in oral language than other children over time, there was no significant difference between summer school and non-summer school children's scores by the middle of kindergarten.
- The centralized higher education system in Turkey and the national music teacher training program since 1998: An analysis.
- The purpose was to analyze Turkey's current music teacher training curriculum as situated in the centralized educational system, focusing on the extent to which the written document (1) reflects the core elements of the overall centralized educational system; (2) prescribes the nature of teaching materials and methods, assessment tools and other forms of evaluating and monitoring performance as teachers and musicians; and (3) acknowledges cultural diversity by addressing repertoire, musical activities and concepts according to geographic and cultural regions. Qualitative-descriptive and quantitative content analysis, including the methods of (a) Inverse document frequency and (b) relevance feedback model, were the analytic tools. Of the required 147 credit hours, 138 are the core. The music core consists of 87 (63%) and the non-music core of 51 credit hours (37%). On paper, there is a conceptual overlap in wording between the music core, the general core, and the teacher training core, suggesting curricular cohesion and consistency. Noticeably less cohesion exists between the document and three major policy papers on teacher competencies. By word count, preparing teachers for instruction in Turkish folk music and multicultural issues appears to hold a low priority in the curriculum. However, course descriptions, where they exist, speak to skills and knowledge linked to performing and understanding Turkish folk and art music, not Western art music alone. Missing from those descriptions is any reference to teaching materials and methods, specific assessment tools, and other forms of evaluating and monitoring students. With reference to works by Max Weber, Karl Mannheim, and Robert Merton, the study concludes with a discussion about issues and problems inherent in a centralized teacher program that seeks to prepare music teachers for a culturally diverse society.
- Educational Opportunities Available for Women in Antebellum Texas
- The matter of formal education for women in the antebellum South raises many questions, especially for the frontier state of Texas. Were there schools for young women in antebellum Texas? If so, did these schools emphasize academic or ornamental subjects? Did only women from wealthy families attend? This study answered these questions by examining educational opportunities in five antebellum Texas counties. Utilizing newspapers, probate records, tax records, and the federal census, it identified schools for girls in all of the counties and found that those schools offered academic as well as ornamental subjects. Almost all of the girls who attended those schools came from privileged families. Schools were available for young women in antebellum Texas, but generally only those from wealthy families were able to attend.
- Development of a Multidimensional Approach to Understanding Youthful Offenders: The Influence of Psychosocial and Personality Risk Factors
- This study employed a multivariate, multidimensional approach to understanding psychosocial and personality variables associated with institutional maladjustment and recidivism among youthful offenders. Participants included nine hundred serious and chronic male youthful offenders incarcerated in the Texas Youth Commission (TYC); sample sizes varied by analysis. Empirically-validated psychosocial factors (e.g., intelligence, home approval status), past criminal history variables, and two self-report personality measures of empathy and hostility were entered into hierarchical regression and structural equation modeling (SEM) analyses to predict institutional behavior and recidivism at one- and three-year intervals after release from the TYC. Confirmatory factor analysis of the personality measures revealed one underlying factor indicative of their theoretical constructs of empathy and hostility. Some differences were noted between youth in the specialized treatment programs; however, effect sizes were small to moderate. Overall, regression and SEM results indicated the variables accounted for a meaningful proportion of the variance in the outcomes. Specifically, although length of stay in the TYC was associated with institutional behavior, younger age of onset, higher hostility, and greater home disapproval also contributed significantly. Past criminal behavior was predictive of future reoffending, but lower empathy, greater home disapproval, and younger age of onset accounted for a substantial portion of the variance in recidivism. Institutional maladjustment served as a mediator between the psychosocial and personality variables and the recidivism outcomes. Treatment implications are provided, including a discussion of the tenuous association between length of sentence and recidivism and an emphasis on the importance of evaluating dynamic personality and psychosocial variables beyond static measures of past behavior.
- Electrochemical Study of Under-Potential Deposition Processes on Transition Metal Surfaces
- Copper under-potential deposition (UPD) on iridium was studied due to important implications it presents to the semiconductor industry. Copper UPD allows controlled superfilling on sub-micrometer trenches; iridium has characteristics to prevent copper interconnect penetration into the surrounding dielectric. Copper UPD is not favored on iridium oxides but data shows copper over-potential deposition when lower oxidation state Ir oxide is formed. Effect of anions in solution on silver UPD at platinum (Pt) electrodes was studied with the electrochemical quartz crystal microbalance. Silver UPD forms about one monolayer in the three different electrolytes employed. When phosphoric acid is used, silver oxide growth is identified due to presence of low coverage hydrous oxide species at potentials prior to the monolayer oxide region oxide region.
- The adoption and use of electronic information resources by a non-traditional user group: Automotive service technicians.
- The growing complexity of machines has led to a concomitant increase in the amount and complexity of the information needed by those charged with servicing them. This, in turn, has led to a need for more robust methods for storing and distributing information and for a workforce more sophisticated in its use of information resources. As a result, the service trades have "professionalized," adopting more rigorous academic standards and developing ongoing certification programs. The current paper deals with the acceptance of advanced electronic information technology by skilled service personnel, specifically, automotive service technicians. The theoretical basis of the study is Davis' technology acceptance model. The purpose of the study is to determine the effects of three external factors on the operation of the model: age, work experience, and education/certification level. The research design is in two parts, beginning with an onsite observation and interviews to establish the environment. During the second part of the research process a survey was administered to a sample of automotive service technicians. Results indicated significant inverse relationships between age and acceptance and between experience and acceptance. A significant positive relationship was shown between education, particularly certification, and acceptance.
- Ethnic Minorities and Prohibition in Texas, 1887 to 1919
- Historians of the prohibition movement in Texas have assumed that the state's main ethnic minorities-Germans, Mexican Americans and African Americans-strongly opposed restrictions on the production, sale, and transportation of alcoholic beverages. This study focuses on the voting patterns in fifteen counties chosen to represent varying percentages of these ethnic minorities in their populations during three statewide anti-alcohol elections (1997, 1911, and 1919) in an effort to determine exactly the extent of opposition to prohibition on the part of ethnic minorities in Texas. It also examines the actions of the prohibitionists and anti-prohibitionists in courting the vote of ethnic minority groups. This analysis and comparison of election results in fifteen counties confirms overwhelming opposition to prohibition on the part of all three of Texas's ethnic minorities.
- The Pettis Integral and Operator Theory
Access: Use of this item is restricted to the UNT Community.
Let (Ω, Σ, µ) be a finite measure space and X, a Banach space with continuous dual X*. A scalarly measurable function f: Ω→X is Dunford integrable if for each x* X*, x*f L1(µ). Define the operator Tf. X* → L1(µ) by T(x*) = x*f. Then f is Pettis integrable if and only if this operator is weak*-to-weak continuous. This paper begins with an overview of this function. Work by Robert Huff and Gunnar Stefansson on the operator Tf motivates much of this paper. Conditions that make Tf weak*-to-weak continuous are generalized to weak*-toweak continuous operators on dual spaces. For instance, if Tf is weakly compact and if there exists a separable subspace D X such that for each x* X*, x*f = x*fχDµ-a.e, then f is Pettis integrable. This nation is generalized to bounded operators T: X* → Y. To say that T is determined by D means that if x*| D = 0, then T (x*) = 0. Determining subspaces are used to help prove certain facts about operators on dual spaces. Attention is given to finding determining subspaces far a given T: X* → Y. The kernel of T and the adjoint T* of T are used to construct determining subspaces for T. For example, if T*(Y*) ∩ X is weak* dense in T*(Y*), then T is determined by T*(Y*) ∩ X. Also if ker(T) is weak* closed in X*, then the annihilator of ker(T) (in X) is the unique minimal determining subspace for T.
- Comparison of Bare Root vs. Potted Plants, Species Selection, and Caging Types for Restoration of a Prairie Wetland, and Quantitative Analysis and Descriptive Survey of Plant Communities and Associations at Lewisville Lake Environmental Learning Area (LLELA), Lewisville, TX
- Lewisville Lake Environmental Learning Area (LLELA) is an 809-hectare property in Denton County, TX. A study of the vegetation community identified 466 species in 104 families, with 25% of the species from only two families, Asteraceae and Poaceae. The property demonstrates the characteristics of an early successional community, dominated by weedy species. Prairie communities are dominated by Johnson grass and ragweed, with climax tall grass prairie communities only in areas that have been planted with native grass seed. Forest communities are similarly in an early successional stage, dominated by the hackberry-elm-ash alliance, with small remnants of native Cross Timbers found in isolated patches. Species richness and diversity were highest in the forests and lowest in the wetlands; evenness, though not different across ecosystems, demonstrated a strong seasonal component. The species list was compared with previously reported lists for Denton County, and 256 species identified had not been previously reported for the county. A wetland restoration study was conducted to determine if there was a difference in survival and growth between potted transplants with intact root systems and bare-root transplants. Two different mesh sizes were used for protection, and the success of the different caging was evaluated. Of eight species, only four survived through the second growing season. There was no significant difference in the success of the propagule types for Sagittaria latifolia. The treatments planted with intact root systems showed significantly higher growth and reproduction than the bare-root treatments for Eleocharis quadrangulata, Heteranthera dubia, and Vallisneria americana. There was no survival recorded in the coarse mesh cages, likely due to the presence of crayfish that are able to get through the coarser mesh and feed on the transplants.
- Concentrations of Triclosan in the City of Denton Wastewater Treatment Plant, Pecan Creek, and the Influent and Effluent of an Experimental Constructed Wetland
- The Pecan Creek Waste Reclamation Plant in Denton, Texas, an activated sludge WWTP, was sampled monthly for ten months to determine seasonal and site variation in concentrations of triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol), an antibacterial additive. SNK separation after the highly significant ANOVA on ranked data were: summer = fall > winter = spring and influent > downstream = effluent = wetland inflow > wetland outflow (a=0.05). After the plant converted to ultraviolet disinfection, measurements were made before and after the UV basin to determine if significant amounts of triclosan were converted to dioxin. Percent loss at each of the treatment steps was determined. Concentrations of triclosan in the downstream site were below the published NOEC for the most sensitive species.
- Ecotoxicological Investigations in Effluent-Dominated Stream Mesocosms
- The University of North Texas Stream Research Facility (UNTSRF) was designed to examine contaminant impacts on effluent-dominated stream ecosystems. Stream mesocosms, fed municipal effluent from the City of Denton, TX, Pecan Creek Water Reclamation Plant (PCWRP), were treated with 0, 15 or 140 µg/L cadmium for a 10-day study in August 2000. Laboratory toxicity test and stream macroinvertebrate responses indicated that cadmium bioavailability was reduced by constituents of effluent-dominated streams. The Biotic Ligand Model (BLM) for Cd was used to predict a 48 hour Cd EC50 for Ceriodaphnia dubia of 280 µg/L in these effluent-dominated streams. This value is higher that an EC50 of 38.3 µg/L Cd and a 7-day reproduction effect level of 3.3 µg/L Cd generated for C. dubia in reconstituted laboratory hard water. These results support use of a cadmium BLM for establishing site-specific acute water quality criteria in effluent-dominated streams. Although not affected by 15 µg/L treatments, organisms accumulated Cd in 15 µg/L treated streams. Hence, over longer exposure periods, Cd accumulation may increase and a no effect level may be lower than the observed 10-day no effect level of 15 µg/L. A toxicity identification evaluation procedure was utilized with in vitro and in vivo bioassays to identify estrogenic compounds in PCWRP effluent, previously identified to seasonally induce vitellogenin (VTG) in male fathead minnows. Steroids, nonylphenol ethoxylate metabolites, and other unidentified compounds were identified as causative effluent estrogens. These findings suggest that in vivo VTG bioassays should be used to confirm in vitro Yeast Estrogen Screening assay activity when effluents are fractionated or screened for estrogenicity. A subsequent 90-day cadmium study was initiated to assess long-term effluent and cadmium effects on fish endocrine function. Juvenile fathead minnows were placed in UNTSRF pool sections of replicate streams treated with 0, 5, 20 or 80 µg/L Cd. Male VTG was induced at each treatment level, indicating that PCWRP effluent was estrogenic during fall 2001. 20 and 80 µg/L Cd treatments reduced male circulating estradiol levels and critical swimming performance. Future studies are needed to assess impacts of environmental estrogen exposure on fish calcium metabolism and vertebral integrity.
- Determination of Habitat Preferences of Pronghorn (Antilocapra americana) on the Rolling Plains of Texas Using GIS and Remote Sensing
- The Rocker b Ranch on the southern Rolling Plains has one of the last sizeable populations of pronghorn (Antilocapra americana) in Texas. To investigate habitat utilization on the ranch, pronghorn were fitted with GPS/VHF collars and were released into pastures surrounded by a variety of fences to determine how fence types affected habitat selection. Habitat parameters chosen for analysis were vegetation, elevation, slope, aspect, and distances to water, roads, and oil wells. Results showed that pronghorn on the ranch crossed modified fencing significantly less than other types of fencing. Pronghorn selected for all habitat parameters to various degrees, with the most important being vegetation type. Habitat selection could be attributed to correspondence of vegetation type with other parameters or spatial arrangements of physical features of the landscape. Seasonal differences in habitat utilization were evident, and animals tended to move shorter distances at night than they did during daylight hours.
- Density, Distribution and Habitat Requirements for the Ozark Pocket Gopher (Geomys Bursarius Ozarkensis)
- A new subspecies of the plains pocket gopher (Geomys bursarius ozarkensis), located in the Ozark Mountains of north central Arkansas, was recently described by Elrod et al. (2000). Current range for G. b. ozarkensis was established, habitat preference was assessed by analyzing soil samples, vegetation and distance to stream and potential pocket gopher habitat within the current range was identified. A census technique was used to estimate a total density of 3, 564 pocket gophers. Through automobile and aerial survey 51 known fields of inhabitance were located extending the range slightly. Soil analyses indicated loamy sand as the most common texture with a slightly acidic pH and a broad range of values for other measured soil parameters and 21 families of vegetation were identified. All inhabited fields were located within an average of 107.2m from waterways and over 1,600 hectares of possible suitable habitat was identified.
- Corridors in Conservation and Philosophy
- My thesis focuses on philosophical themes implicit in corridor conservation, using the Big Thicket National Preserve as an example. The way in which corridors, boundaries and communities are ambiguous, as both limits and connections, is dealt with. Corridor-patch matrices assemble ecological and human groups into temporary communities, often with conflicting interests. Such constellations foreground how a foreigner's boundary crossing is a notion important to both conservation and a philosophical study of being, seen as being always in relation with otherness. In this context, the notion of foreignness and Jean-Luc Nancy's idea of being-with is explored. Understanding the complex network of relations in which an entity exists leads to an awareness of its ambiguous nature. To facilitate judgment with such ambiguity, one needs a contextual understanding of a situation.
- Effects of Sublethal Copper Exposure on Escape Behavior and Growth of Rana pipiens Tadpoles
- This research is designed to test how sublethal exposure to copper affects tadpole predator-escape behavior and how quickly tadpoles recover. After exposure, tadpoles were separated. Escape behavior was recorded for two-thirds of exposed tadpoles while one-third of the exposed population was measured weekly to determine growth and recovery. Control tadpoles were consumed within 15 minutes whereas those exposed to higher concentrations were consumed at a slower rate, which does not support the hypotheses. Although the rate of predation was lower, tadpoles exposed to higher Cu concentrations were on average, 1.47 cm in total body length. Those exposed to 0.93 mg/L averaged 0.86 cm. After being placed into clean water, treatment tadpoles recovered after 20 days.
- A Stranger Amongst Strangers: An Analysis of the Freedmen's Bureau Subassistant Commissioners in Texas, 1865-1868
- This dissertation is a study of the subassistant commissioners of the Freedmen's Bureau in Texas from late 1865 to late 1868. Its focus is two-fold. It first examines who these men were. Were they northern born or southern? Did they own slaves? Were these men rich, poor, or from the middle-class? Did they have military experience or were they civilians? How old was the average subassistant commissioner in Texas? This work will answer what man Freedmen's Bureau officials deemed qualified to transition the former slave from bondage to freedom. Secondly, in conjunction with these questions, this work will examine the day-to-day operations of the Bureau agents in Texas, chronicling those aspects endemic to all agents as well as those unique to certain subdistricts. The demand of being a Bureau agent was immense, requiring long hours in the office fielding questions and long hours in the saddle inspecting subdistricts. In essence, their work advising, protecting, and educating the freedmen was a never ending one. The records of the Freedmen's Bureau, both the records for headquarters and the subassistant commissioners, serve as the main sources, but numerous newspapers, Texas state official correspondences, and military records proved helpful. Immense amounts of information arrived at Bureau headquarters from field personnel. This work relies heavily on reports and letters in the Bureau agents' own words. This dissertation follows a chronological approach, following the various Bureau administrations in Texas. I believe this approach allows the reader to better glimpse events as they happened.
- Comparison of client attendance, attrition, and outcomes in 2 class system packages.
- Using the principles of systems analysis as a guide, this study compared two class schedule formats used by Behavior Management and Parenting Services (BMAPS) in order to address the following research questions: 1) What effects do 2 different class formats have on student attrition and appointment keeping? 2) What effects do 2 different class formats have on student outcomes on a pre and posttest assessment? 3) What effects do 2 different class formats have on staff procedures? BMAPS provides parent education to individuals referred by Child Protective Services. The current research included approximately 200 referred clients with an appointment or class scheduled with BMAPS between January 1, 2006 and September 22, 2007. Data was collected by reviewing client files for class attendance and performance records. Results of this study allow BMAPS to enlist the class format that is correlated with better attrition rates and client outcomes.
- From Block to Traditional Schedule: The Impact on Academic Achievement, Attendance Rates, and Dropout Rates
- The purpose of this study was to examine the impact of school schedule on student achievement and attendance of ninth and tenth grade students in metropolitan area Texas high schools (n = 22) and campus dropout rates. High schools that were analyzed in this study made a transition from A/B block scheduling in the 2003-04 school year to a traditional school schedule in the 2004-05 school year. Academic achievement, attendance rates and dropout rates were gathered through the archived files of the Texas Agency through the Academic Indicator of Excellence System (AEIS). Academic achievement was measured by the Texas Assessment of Knowledge and Skills (TAKS) Reading/Language Arts and Mathematics standardized tests. This study compared the mean scores of ninth grader student achievement, attendance, and dropout rates from the 2003-04 school year to the mean scores of the tenth graders from the same schools from the 2004-05 school year, after the schools converted from an A/B block schedule to a traditional class schedule. Each independent variable was divided into four subgroups; campus mean results, minority student results, limited English proficient (LEP) student results, and low-socioeconomic student results. Students under the A/B block scored significantly higher in reading achievement than when they were instructed the following year under a traditional schedule. Paired sample t-tests were conducted to analyze the data for each subgroup, and showed there was a statistically significance in reading / language arts student achievement scores for all subgroups. Statistical significance was determined with a ninety five percent confidence level (p < 0.05). Statistical analysis revealed varied results in mean scores for math academic achievement and attendance rates, but no statistical significant difference. Comparison of data showed a slight increase in mean scores for dropout rates in traditional schedule, however the results were not significant.
- The skazki (fairy tales) of Nikolai Medtner: The evolution and characteristics of the genre with compositional and performance aspects of selected fairy tales.
- The compositional language of Russian composer-pianist Nikolai Medtner (1880-1951) demonstrates an evolution of the traditional forms and harmony. Following the classical and romantic traditions, Medtner's compositional technique reveals his individual and original approaches to form and harmony. The unique architectonic in his works is achieved through particular tonal-harmonic juxtapositions of the sections, the frequent prevalence of the monothematic principle, the increased role of the developmental material in the exposition, and contrapuntal combination of themes. Harmonic vocabulary is characterized by chromatic harmony, altered dissonant chords, augmented triads, complex chains of modulations, and usage and combination of modes and octatonic scale. Counterpoint is of great importance toward understanding the chord progression found in his music. Skazki (fairy tales) are pieces in small form, such as preludes, or novelettes; they hold an important place in Medtner's oeuvre. The fairy tale genre is associated with many artistic traditions, including Russian folk art. Medtner's 38 fairy tales, varied in imagery and character, were composed during different periods of his life. The evolution of the genre is seen in form and harmonic language. The lyrical, subjective mood of the fairy tales of the earlier period, such as op. 8, op. 9 and op. 14, evolve into large-scale works, such as fairy tales op. 20 and op. 35. In his later years, in fairy tales from op. 42, Medtner imbues the form with a greater clarity of expression, a tendency to move toward simpler musical expression, and an expanded use of thematic Russian folklore sources, including more definite ties with song and dance genres.
- Personality and the prediction of outcome following rehabilitation in persons with acquired brain injuries: The Millon Behavioral Medicine Diagnostic (MBMD).
- Neuropsychological rehabilitation following acquired brain injury is increasingly recognized as essential with the advancements in research evidence of its effectiveness, particularly as current estimates of disability following the most common forms of brain injury (traumatic brain injury and cerebrovascular accident) are so high. Improvements in predictive capabilities of researchers and clinicians are paramount in designing effective interventions. As many variables associated with outcome following brain injury are not controllable (e.g. severity of the injury, age, education), it is essential that rehabilitation programs design interventions to target those variables that are susceptible to amelioration. While personality factors have been shown to affect outcome in other medical illnesses, only a few studies have examined the influence of personality on outcome following neurorehabilitation for acquired brain injury. The results of these studies have been mixed. This study used the Millon Behavioral Medicine Diagnostic (MBMD) to predict outcome as measured by the Mayo-Portland Adaptability Index (MPAI-4) following brain injury rehabilitation in a heterogeneous sample of persons with acquired brain injuries (N = 50). It was hypothesized that specific coping styles scales from the MBMD (Introversive, Dejected, Oppositional), which are based on Millon's personality system, would predict outcome. Results indicated that both the Introversive and Oppositional coping styles scales accounted for significant amounts of variance in outcome beyond that accounted for by the severity of the injury alone (p < .001). In both cases, individuals with mild/moderate-moderate/severe limitations following completion of the rehabilitation program had significantly higher scores on the Introversive and Oppositional coping compared to individuals with more successful outcomes. The hypothesis that a dejected coping style would predict outcome was not supported. Implications for rehabilitation are discussed in the context of Millon's personality system.
