A Performer's Analysis of Lili Boulanger's Clairières dans le ciel: Song Cycle for High Voice and Piano; a Lecture Recital Together with the Role of Blanche in Dialogues of the Carmelites by F. Poulenc and Two Recitals of Selected Works by H. Purcell, F. Schubert, S. Prokofieff, E. Chausson, W. A. Mozart, R. Schumann and G. Fauré

Description: Lili Boulanger was an important composer of early twentieth century French music. Her compositional style represents a development and mastery of musical techniques of the great composers of her time including Fauré, Debussy and Wagner combined with her own creative expression. The result is a compelling musical language that was uniquely her own. She held an important place among her contemporaries in Paris and her accomplishments were considered newsworthy during her lifetime (1893- 1918). She obtained a much sought-after publishing contract with Ricordi. Her more famous sister, Nadia Boulanger, felt that Lili was the better composer of the two, and her peers and music professors clearly felt that both her musical and personal qualities were extraordinary. Evidence of her intelligence, creativity, and artistic growth can be seen in her music. As the first woman to win the Prix de Rome (July 5, 1913), Lili Boulanger, unlike Clara Schumann, Fanny Mendelssohn, or Alma Mahler, was acknowledged and acclaimed during her lifetime for her skill as a composer. Yet, nearly a century later the music of this talented French composer is not as well known as it deserves to be. In an effort to discover the reasons for this relative anonymity, this document will examine Lili Boulanger's life including her family and childhood influences, musical training, preparation for the Prix de Rome and the influence of Claude Debussy and other composers. This document will discuss her mature compositional style, specifically as it is reflected in her song cycle, Clairières dans le ciel. The text will be examined in conjunction with the literary movement of symbolism in 20th century France and the symbolist poet, Francis Jammes, with special attention to the composer's personal identification with the poetry. Considerations of the musical setting of the cycle will include the melodic style as it relates ...

Effects on Survival, Reproduction and Growth of Ceriodaphnia dubia following Single Episodic Exposure to Copper or Cadmium

Description: Effects of episodic exposures have gained attention as the regulatory focus of the Clean Water Act has shifted away from continuous-flow effluents. Standardized laboratory toxicity tests require that exposure be held constant. However, this approach may not accurately predict organism responses in the field following episodic exposures such as those associated with rain-driven runoff events or accidental pollutant discharge. Using a modified version of the 7-day short-term chronic test recommended by the US Environmental Protection Agency, Ceriodaphnia dubia were exposed to copper or cadmium for durations ranging from 1 minute to 24 hours. In addition, adult reproductive recovery and effects on second generation individuals was assessed following select copper exposures. Finally, cadmium exposures were compared in reconstituted hard water (RHW) and municipal treated wastewater effluent (TWE). Following exposure, organisms were transferred to clean RHW or TWE and maintained for the remainder of the test. No- and lowest observed effect concentrations (NO- and LOECs) increased logarithmically with respect to logarithmic decreases in duration regardless of metal, endpoint or water type. Effective concentrations of cadmium however, were usually higher than those of copper, especially in TWE. LOECs for C. dubia survival following 24-hour and 5-minute exposures to copper were 116 and 417 µg/L, respectively. LOECs for fecundity were 58 and 374 µg/L, respectively. Neonate production of first generation adult C. dubia appeared to recover from pulsed copper exposure upon examination of individual broods. Cumulative mean neonate production however, showed almost no signs of recovery at exposure durations ≥3 hours. Pulse exposure to copper also resulted in diminished fecundity of unexposed second generation individuals. Such effects were pronounced following parental exposure for 24 hours but lacking after parental exposures ≤3 hours. LOECs for C. dubia survival following 24-hour and 5-minute exposures to cadmium in RHW were 44 and 9000 µg/L, respectively. LOECs for ...

Relationship of the PDI Employment Inventory Scales to Criminal Behaviors

Description: This study investigated the relationship of the Personnel Decisions International Employment Inventory scales to criminal behavior by using 796 offenders with criminal records in the Texas Department of Corrections and a random sample of 893 non-offender job applicants. The hypothesis that offenders would score lower in integrity scores than non-offenders only gained mixed support, but consistent evidence showed that there were no mean differences between property offenders and other offenders. The implications of the results for future study were discussed.

Distance Education in the Preparation of Special Education Personnel: An Examination of Videoconferencing and Web-based Instruction

Description: This study examined the effectiveness of employing videoconferencing and Web-based instruction in the preparation of special education personnel. Due to the acute shortage of special education personnel, it was anticipated that the use of videoconferencing and online instruction would provide a convenient way for students to attend class without having to travel to the actual location of the educational site. Further, it was believed that this initiative would result in higher student enrollment in special education teacher certification programs, consequently leading to an increase of personnel in the field. Moreover, the increase in personnel would enhance the ability of educational institutions to address the dismal academic, social, and behavioral outcomes of students with disabilities. Information for the study was collected from surveys that investigated how students perceived the use of videoconferencing and web-based instruction in the preparation of special education personnel. Ninety-four graduate students responded to the videoconferencing surveys while 88 responded to the Web-based instruction surveys. Six respondents were randomly selected to participate in face-to-face interviews designed to investigate the effectiveness of both approaches. Findings indicated that videoconferencing and Web-based instruction are convenient ways for students to attend class although videoconferencing sites may not be conveniently located to all learners. Furthermore, the effectiveness of these media depends on several factors: the instructor, the course structure, the learners' learning styles, the quality and quantity of interaction between learners and the instructor, and whether technological problems interfere with the learning process. The study determined that the more structured and organized the course, the more significant the learning outcomes. Also, the maturity level of the students lends itself to accountability toward achieving the desired learning goals. Technological problems and the lack of user-friendly technology lower the effectiveness of videoconferencing and Web-based instruction. Further research will be valuable in improving theories and approaches ...

Organizational Change Development Interventions: Are Multiple Interventions Useful?

Description: The effects of multiple interventions in organizational development change were studied in a comprehensive meta-analytic review. Thirteen organizational interventions were assessed on five outcome variables based upon previous research of six major meta-analytic reviews. Findings based on 138 studies indicated that there were no significant effects of multiple interventions on positive organizational change as opposed to individually implemented interventions. The findings are not congruent with previous findings of organizational development change, and possible issues surrounding these differences are discussed.

Descriptive Analysis of Comments Obtained during the Process of Regulating the Reauthorization of the Individuals with Disabilities Act of 2004

Description: This study examined the comments submitted by the public to the United States Department of Education (USDE), the Office of Special Education Programs, in response to the 2004 amended IDEA, prior to the development and publication of proposed regulations under 34 Code of Federal Regulations (CFR) parts 300 and 303 to implement programs under IDEA. Specifically, this study analyzed the types of individuals (e.g., parents, advocates, administrators, lawyers, support staff personnel) and interest groups along with the number of submissions, types of comments made, and specific provisions in the legislation that received the most comments during the period open to the public prior to the publication of the proposed regulations. In addition, an exploration of the existence of differences in comments submitted by states and regions was analyzed in terms of types of individuals, interest groups, types of comments, and specific provision of the 2004 amended IDEA. Content analysis approach utilizing qualitative data collection and analysis procedures was used for this study. The sample consisted of 2,199 comments submitted to the USDE via the U.S. Postal system, e-mail, and verbal testimony transcripts obtained during one of the public meetings held throughout the United States during the 60 day period open for commenting. The findings of this study revealed a large number of a particular type of respondent types, the majority of the comments were neutral in nature, and the largest percentage of comments received were directed at one particular section of the Act.

Religiosity and spirituality in younger and older adults.

Description: The present study examined the use of MacDonald's Expressions of Spirituality instrument with a younger and older adult sample. Specifically, MacDonald's proposed five factor model was assessed for fit with a sample of college age participants as well as a sample of adults over the age of 65. A confirmatory factor analysis was conducted to assess the fit of this model with samples, and this was followed by an exploratory factor analysis, and the results were considered in light of measurement equivalence and the definitions of the constructs of religiosity and spirituality. Further analyses examined levels of religiousness as well as relationships between religiousness/spirituality and potential correlates, such as postformal thinking, life events including changes and losses, emotional and physical well-being, and family upbringing, comparing young and older adult samples. Results of the confirmatory factor analysis revealed a solution with a better fit than MacDonald's model for both younger and older adults. While the number of factors were the same for both samples, item loadings and cross-loadings differed between the younger and older adult samples. Exploratory factor analysis yielded a four factor solution, with religiousness and spirituality items loading onto one factor. With regard to measurement equivalence, findings appear to indicate that the five factor solution and MacDonald's Expressions of Spirituality instrument may not be as useful with older adults. Additionally, findings are discussed with regard to the measurement of the constructs of religiosity and spirituality. In addition to measurement issues, several findings pointed to differences between the younger and older adult samples. For young adults, more life changes were related to higher levels of postformal thinking, but for older adults more life losses were related to higher levels of postformal thinking. Also, the older adult sample had higher levels of religiousness than the young adult sample. Several results were ...

An Assessment on the Impact of Family Dynamics on the Runaway Problem Among Teenagers

Description: Although Turkey is a country with strong social cohesion, figures of runaway children in Turkey are increasing dramatically. This research focused on the factors that cause children to run away and on interaction programs to intervene and/or prevent this problem. Until recently, Turkish family life was able to avoid such problems, but with the effect of westernization and social mobility in Turkey, the basic family structure has become more like the family structure in the western countries. Studies reveal that runaway episodes happen in all families regardless of such factors as economic, race, or geographic situations. Teenagers run away for several reasons; however, early intervention is highly suggested by studies to mitigate the problem. Although, parent-child conflict plays a significant role as a reason for youth leaving home, on the other hand family interaction still remains the best alternative to the problem.

Evaluation of a Training Package for Teaching Social Skills in an Inclusionary Preschool Environment

Description: Effective training procedures are necessary when teaching behavior analytic techniques because the techniques are so complex and precise; and there is a correlation between the changed skills in the trainees to be beneficial to the client. Instructors who may previously exhibit effective teaching techniques in a one-to-one setting may not exhibit those techniques in an inclusive setting. This study examines the effects of a training package and an instruction on the performance of experienced instructors, and desired responding from both preschool-aged children with autism and typically developing peers. The training took place with 3 triads of one instructor, one child with autism, and one peer in a center-based inclusionary preschool. Instructor skills targeted were prompt and consequence delivery for the target social skills, getting attention and responding to peers. Corroborative data on children's responding were obtained.

Study of Ruthenium and Ruthenium Oxide's Electrochemical Properties and Application as a Copper Diffusion Barrier

Description: As a very promising material of copper diffusion barrier for next generation microelectronics, Ru has already obtained a considerable attention recently. In this dissertation, we investigated ruthenium and ruthenium oxide electrochemical properties and the application as a copper diffusion barrier. Cu under potential deposition (UPD) on the RuOx formed electrochemically was first observed. Strong binding interaction, manifesting by the observed Cu UPD process, exists between Cu and Ru as well as its conductive ruthenium oxide. Since UPD can be conformally formed on the electrode surface, which enable Ru and RuOx has a potential application in the next generation anode. The [Cl-] and pH dependent experiment were conducted, both of them will affect UPD Cu on Ru oxide. We also found the Cu deposition is thermodynamically favored on RuOx formed electrochemically. We have studied the Ru thin film (5nm) as a copper diffusion barrier. It can successfully block Cu diffusion annealed at 300 oC for 10min under vacuum, and fail at 450 oC. We think the silicidation process at the interface between Ru and Si. PVD Cu/Ru/Si and ECP Cu/Ru/Si were compared each other during copper diffusion study. It was observed that ECP Cu is easy to diffuse through Ru barrier. The function of RuOx in diffusion study on Cu/Ru/Si stack was discussed. In pH 5 Cu2+ solution, Ru and Pt electrochemical behavior were investigated. A sharp difference was observed compared to low pH value. The mechanism in pH 5 Cu2+ solution was interpreted. An interesting compound (posnjakite) was obtained during the electrochemical process. An appropriate formation mechanism was proposed. Also Cu2O was formed in the process. We found oxygen reduction reaction is a key factor to cause this phenomenon.

Effect of Early Childhood Teacher Characteristics on Classroom Practice, Quality, and Child Abilities

Description: The National Institute of Child Health and Human Development (NICHD) is funding and supporting a longitudinal study of Early Child Care. Beginning in 1991, data was collected from ten sites across the United States and included 1,364 families with a newborn child. This study used the NICHD Early Child Care data set to investigate characteristics of teachers that provide childcare in a daycare-like setting or childcare centers. Specifically, the relationship between early childhood teacher endorsement of developmentally appropriate belief systems and teacher education in early childhood were examined to determine their potential influence on the teachers' developmentally appropriate classroom practices, global rating of classroom quality, and child cognitive abilities. These relationships were examined at two time periods- at child age 36 months and child age 54 months. The results indicated that many of these relationships were significant. Interestingly, many of the significant findings were present only at child age 54 months.

The Paradox of Creativity and Business in Feature Hollywood Filmmaking: The Relationship Between Motion Picture Production and Budgeting

Description: This study examines the relationship between movie budgeting and the creative process in Hollywood filmmaking. To understand the effects of this relationship on the creative product, several films are analyzed within the production process where conflicts between the investors and creators are observed. A case study approach is guided by theories of the production of culture, which state that creative products manufactured in the cultural industry must be analyzed in relation to their surrounds society. Findings suggest previous indicators of box office success are becoming primary influences in the filmmaking process. The study also finds that financial standards in Hollywood potentially inhibit innovation among creative participants within a limited Hollywood creative sphere.

Mutation of Polaris, an Intraflagellar Transport Protein, Shortens Neuronal Cilia

Description: Primary cilia are non-motile organelles having 9+0 microtubules that project from the basal body of the cell. While the main purpose of motile cilia in mammalian cells is to move fluid or mucus over the cell surface, the purpose of primary cilia has remained elusive for the most part. Primary cilia are shortened in the kidney tubules of Tg737orpk mice, which have polycystic kidney disease due to ciliary defects. The product of the Tg737 gene is polaris, which is directly involved in a microtubule-dependent transport process called intraflagellar transport (IFT). In order to determine the importance of polaris in the development of neuronal cilia, cilium length and numerical density of cilia were quantitatively assessed in six different brain regions on postnatal days 14 and 31 in Tg737orpk mutant and wildtype mice. Our results indicate that the polaris mutation leads to shortening of cilia as well as decreased percentage of ciliated neurons in all brain regions that were quantitatively assessed. Maintainance of cilia was especially affected in the ventromedial nucleus of the hypothalamus. Furthermore, the polaris mutation curtailed cilium length more severely on postnatal day 31 than postnatal day 14. These data suggests that even after ciliogenesis, intraflagellar transport is necessary in order to maintain neuronal cilia. Regional heterogeneity in the effect of this gene mutation on neuronal cilia suggests that the functions of some brain regions might be more compromised than others.

Group sandtray therapy at school with preadolescents identified with behavioral difficulties.

Description: Sandtray therapy, a modality of play therapy, has been used in a variety of ways as the treatment intervention with different theoretical approaches; however, there is a very limited amount of empirical research. The purpose of this research is to examine the effectiveness of group sandtray therapy at school with preadolescents identified with behavioral difficulties. This is a pretest-posttest control group design. Participants in the experimental group received sandtray therapy in group for ten weeks, and participants in the wait-list control group received no treatment intervention. The researcher compared two groups to examine the overall effectiveness of sandtray therapy as determined by the scores of the Child Behavior Checklist-Teacher Report Form (CBC-TRF), Parent Report Form (BASC-PRF), and Self Report of Personality (BASC-SRP). Based on teachers' reports, statistically significant difference existed between the two groups in terms of preadolescents' overall behaviors, externalizing behavior problems, and internalizing behavior problems after the ten week treatment intervention. The effect sizes were medium (d= .52-.59). According to parents' reports, a statistically significant difference was found regarding preadolescents' externalizing behavior problems, and the effect size was medium (d=.63). No statistically significant differences were found regarding preadolescents' total behaviors and internalizing behavior problems based on BASC-PRF. The effect sizes arranged from medium to small (d=.55 and .35, respectively). In terms of the total behavior on BASE-SRP, no statistical significant difference was found and the effect was small (d=.18). A case example was included to illustrate the process and effect of group sandtray therapy. Based on the results of this study, it is determined that group sandtray can be an effective treatment intervention for preadolescents identified with behavioral problems. The primary contribution of this study is to present empirical support for the effectiveness of using sandtray therapy.

A transaction costs explanation of inter-local government collaboration.

Description: This study develops a model of collaboration choice among city governments. The theoretical model suggests that collaboration is a function of transaction costs that vary with different institutional arrangements utilized in cities, as well as the degree of competition between cities. This study argues that cities facing high transaction costs and high competition are less likely to participate in collaboration and to participate less deeply. Underlying these environmental factors are resource factors that create incentives for cities to collaborate for efficiency gains, which affect both the decision to collaboration and the depth of collaboration. Eleven hypotheses are presented to explain why cities choose to participate in collaboration in the first stage of the analysis and how deeply they collaborate in the second stage. Utilizing a Heckman model of this two-stage process, I find broad support for a number of variables that measure each of these theoretical constructs.

A Comparative Analysis of Diseases Associated with Mining and Non-Mining Communities: A Case Study of Obusai and Asankrangwa, Ghana

Description: Disease prevalence varies with geographic location. This research pursues a medical geographic perspective and examines the spatial variations in disease patterns between Obuasi, a gold mining town and Asankrangwa, a non gold mining town in Ghana, West Africa. Political ecology/economy and the human ecology frameworks are used to explain the prevalence of diseases. Mining alters the environment and allows disease causing pathogens and vectors to survive more freely than in other similar environments. Certain diseases such as upper respiratory tract infections, ear infections, sexually transmitted diseases such as HIV/AIDS and syphilis, certain skin diseases and rheumatism and joint pains may have a higher prevalence in Obuasi when compared to Asankrangwa due to the mining in Obuasi.

On the effects of extended sample-observing response requirements on adjusted delay in a titrating delay matching-to-sample procedure with pigeons.

Description: A common procedural variation that facilitates the acquisition of conditional discriminations is to increase the time an organism spends in the presence of the sample stimulus by programming extended sample-observing response requirements. Despite their common use, there has been little empirical investigation of the effects of extended sample-observing response requirements. In the current study, four pigeons worked on a titrating delay matching-to-sample procedure in which the delay between sample offset and comparison onset was adjusted as a function of the pigeons' accuracy. The number of responses required to produce the comparison array was manipulated across conditions. Results show that all subjects were able to withstand longer delays between sample offset and comparison onset as sample-observing response requirements increased. These data show that the extent of the response requirement in the presence of the sample has systematic effects on conditional discrimination performances and should be considered in the design of experiments.

Neuroticism and Religious Coping Styles as Mediators of Depressive Affect and Perceived Stress

Description: Previous researchers have shown that the collaborative, self-directing, and deferring styles of religious coping result in different outcomes of depression under different levels of perceived stress. Neuroticism has also been shown to affect coping effectiveness overall or choice of coping method. However, little work has been done to investigate the association between neuroticism and the choice or effectiveness of religious coping styles in particular, or on the association of neuroticism and perceived stress. The present study addressed research questions by examining relations among neuroticism, perceived stress, objective life events, religious and non-religious coping styles, effectiveness of coping styles, and depression. Hierarchical multiple regression and correlational techniques found that religious coping styles predict depression, religious and non-religious coping correspond, and neuroticism predicts perceived stress beyond situational stressors. Neuroticism did not predict use of religious coping styles, but remaining personality factors were successful in predicting coping. Implications, limitations, and future directions are discussed.
