Experiencing the interdependent nature of musicianship and educatorship as defined by David J. Elliott in the context of the collegiate level vocal jazz ensemble.

Examination of the relationship of musicianship and educatorship of teacher and students as interacting partners in a specific musical context proceeded with investigation of how formal, informal, impressionistic, and supervisory musical and educational knowledge were evidenced in rehearsal. Attention was also given to how the teaching strategies of modeling, coaching, scaffolding, fading, articulating, reflecting comparatively, and exploring were used to develop student musicianship. The research methodology may best be described as an inductive analytical case study approach. Multiple data sources included: videotaped observations of 19 bi-weekly rehearsals, audio taped interviews of the 12 participants, supplemental materials, (a published interview, journal articles, rehearsal schedules), and member checking with the teacher and David Elliott. Rehearsal data were initially organized into categories identified in David J. Elliott's (1995) model. The relationship of teacher and student musicianship, and teacher educatorship emerged during analysis. Musical details of problem finding, reducing and solving were also identified. Three themes emerged from the student interviews: their perceptions of the teacher's musicianship, general rehearsal strategies, and the teacher's use of specific teaching strategies. Interviews with the teacher illuminated his perception of musicianship and teaching strategies employed in the context. The findings confirmed that as music making transpired in the …

The Relationship Between Career and Technical Education and Texas Assessment of Academic Skills and Other Academic Excellence Indicators (open access)

The Relationship Between Career and Technical Education and Texas Assessment of Academic Skills and Other Academic Excellence Indicators

This study examined the relationship between Career and Technical Education (CATE) and the Academic Excellence Indicator System (AEIS), the measure of school and learner success in Texas. CATE, an established program, traditionally encourages student achievement and perpetuates best educational practices. AEIS data was collected by the Texas Education Agency. In addition, a survey was used to measure CATE effectiveness and the relationship between effectiveness and AEIS performance. Two-factor mixed repeated measures ANOVAs were used to observe group differences over time. CATE and non-CATE exit level TAAS scores for reading and math at the district level were analyzed for 2000, 2001, and 2002. CATE students had higher group means but there was not statistical significance indicating that CATE students performed as well as non-CATE. Two-factor mixed repeated measures ANOVAs were also used for analysis of differences at the district level for attendance, dropout rates, and graduation rates. There were higher group means for attendance for CATE students and there was also statistical significance indicating that CATE students attended more often then non-CATE students. There was a lower group means for dropout rate and there was also statistical significance between groups over time. This was an inverse relationship indicating that CATE students …

Organizational Change Development Interventions: Are Multiple Interventions Useful?

Access: Use of this item is restricted to the UNT Community
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.

Organizational development: A comparison of individual and organizational level change.

Access: Use of this item is restricted to the UNT Community
Organizational change and development (OCD) has been studied by researchers to identify the effectiveness of change initiatives. Because of the broad scope of interventions in OCD, these studies have covered a range of areas including multiple interventions and the methodological rigor used by researchers. However, few have looked at organizational versus individual change within an organization, to examine whether individual change is more effective than organizational change. The purpose of this study is to determine if organizational change occurs in a top down or bottom up manner. A meta-analysis was conducted using 238 field experiments. Each study was coded for intervention and organizational outcome and for individual or organizational level variables. Effect sizes were calculated for each study, each level, and each level by intervention and outcome measure. Results indicate that while OCD interventions overall had a moderate effect size, the level of intervention or outcome was not a moderating variable.

Emotional Intelligence at Mid Life: A Cross Sectional Investigation of Structural Variance, Social Correlates, and Relationship to Established Personality and Ability Taxonomies (open access)

Emotional Intelligence at Mid Life: A Cross Sectional Investigation of Structural Variance, Social Correlates, and Relationship to Established Personality and Ability Taxonomies

Emotional Intelligence (EI) has been relatively unstudied after young adulthood. Yet there are a variety of reasons to expect that EI may be different at mid life than in young adulthood. Normative life experiences may lead to increases in EI, and as the array of different environments and experiences increases with age, one might expect greater individual differences in EI. Similarly, if EI is located somewhere at the intersection of personality and intelligence, as some have speculated, it may follow a course of structural differentiation similar to cognitive abilities. EI may be more closely linked to social variables such as loneliness and friendships at mid life, and its relation to established personality and ability factors such as the Big Five (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) and fluid and crystallized abilities may also vary with age. These hypotheses were investigated in samples of 292 young adults and 246 mid life adults, using the Schutte Self Report Emotional Intelligence Inventory, the NEO-Five Factor Personality Inventory, markers of crystallized and fluid ability from Horn's Crystallized/Fluid Sampler, and a variety of other measures. Mid life adults scored higher on overall EI scores, but evidenced no greater range of individual differences than did young …

Parental decision-making regarding their child's participation in a middle-school talent search. (open access)

Parental decision-making regarding their child's participation in a middle-school talent search.

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

Determination of Dissociation Constants for GABAA Receptor Antagonists using Spontaneously Active Neuronal Networks in vitro

Access: Use of this item is restricted to the UNT Community
Changes in spontaneous spike activities recorded from murine frontal cortex networks grown on substrate-integrated microelectrodes were used to determine the dissociation constant (KB) of three GABAA antagonists. Neuronal networks were treated with fixed concentrations of GABAA antagonists and titrated with muscimol, a GABAA receptor agonist. Muscimol decreased spike activity in a concentration dependent manner with full efficacy (100% spike inhibition) and a 50% inhibitory concentration (IC50) of 0.14 ± 0.05 µM (mean ± SD, n=6). At 10, 20, 40 and 80 µM bicuculline, the muscimol IC50 values were shifted to 4.3 ± 1.8 µM (n=6), 6.8 ± 1.7 µM (n=6), 19.3 ± 3.54 µM (n=10) and 43.5 µM (n=2), respectively (mean ± SD). Muscimol titration in the presence of 10, 20, 40 µM of gabazine resulted in IC50s values of 20.1 (n=2), 37.17 (n=4), and 120.45 (n=2), respectively. In the presence of 20, 80, and 160 µM of TMPP (trimethylolpropane phosphate) the IC50s were 0.86 (n=2), 3.07 (n=3), 6.67 (n=2) µM, respectively. Increasing concentrations of GABAA antagonists shifted agonist log concentration-response curves to the right with identical efficacies, indicating direct competition for the GABAA receptor. A Schild plot analysis with linear regression resulted in slopes of 1.18 ± 0.18, 1.29 …

The Role of Motivation in Second Language Pronunciation (open access)

The Role of Motivation in Second Language Pronunciation

This thesis investigates the phonological ability of exceptional second language (L2) learners of English and their levels of motivation. This study is the first of its kind to do a large-scale examination of L2 learners whose first languages (L1s) do not belong to the same Indo-European language family as English. Fifteen non-native speakers (NNSs) of English filled out a questionnaire and produced four speech samples, including a picture description task, paragraph reading task, sentence reading and word reading task. Fifteen native speaker (NS) controls also produced the same speech samples. Four NSs judged all participants' accents. Six NNSs scored as highly as NSs on some of the speech segments using a 2-standard deviation (SD) cut-off point. There was no significant correlation between their scores on pronunciation and motivation.

A Comparison of Brief Versus Extended Paired-Choice Preference Assessment Outcomes. (open access)

A Comparison of Brief Versus Extended Paired-Choice Preference Assessment Outcomes.

Few studies have systematically evaluated whether preferences can reliably be identified using brief procedures. Typically, studies have used brief procedures to select potential reinforcers for use in intervention procedures. A total of 17 food and leisure paired-choice preference assessments were administered to 10 subjects in order to evaluate the extent to which the results of a brief (i.e., single-session) assessment correspond with those from more extended procedures (i.e., 5 sessions). Eleven out of the 17 brief and extended assessments identified the same stimulus as the most preferred (highest rank). Outcomes suggest that a brief assessment can be useful when a single, potent reinforcing stimulus is desired, and an extended assessment should be conducted when a larger number of preferred stimuli is desired.

Parental Understanding and Satisfaction with Special Education Services in the State of Texas (open access)

Parental Understanding and Satisfaction with Special Education Services in the State of Texas

Parental participation in educational issues is relevant in assisting parents in understanding and becoming satisfied with their child's educational experience. Parental involvement is not only an ethical issue for teachers, but mandates have been established for special educators through various public laws. When involving parents in their children's education, it is relevant to consider various factors associated with students who are culturally and linguistically diverse. Parental satisfaction plays an important role in many cultures in obtaining parental involvement in decision-making meetings. If parents experience negative interactions, parental participation can be diminished. In other cultures, the satisfaction level raises parental trust in allowing school staff to make the appropriate choices for their children. Family values and beliefs among the various cultures should be a consideration when encouraging parents to participate in their child's educational process. Several barriers exist when involving different cultural groups; therefore, it is essential for educators to become aware of these barriers and learn strategies to overcome them. This study addresses parental understanding and satisfaction among ethnic group and throughout various disability groups by evaluating parental responses from a statewide survey and three focus groups.

Access: Use of this item is restricted to the UNT Community
Meta-parenting, defined as parents thinking about their parenting, has been identified and is a new field of research. The purposes of this study were to add to the existing knowledge of meta-parenting and to compare the influences of gender, work status, and parenting experience on meta-parenting occurring in parents of infants and toddlers. Sixty parents participated either electronically or by completing a written survey and reported engaging from "sometimes" to "usually" in four domains of meta-parenting: anticipating, assessing, reflecting, and problem-solving. Gender, work status, and parenting experience did not significantly influence participants' meta-parenting scores. Parents were found to have a higher sense of satisfaction and overall sense of competence when they engaged in higher levels of meta-parenting.

Exploring Lifestyle Orientation, Attitudes Toward Lifestyle Merchandising, and Attitudes Toward Lifestyle Advertising as Predictors of Behavioral Intention to Purchase Lifestyle Home Furnishing Products

A number of lifestyle merchandising and advertising strategies are being used in the home furnishings industry. However, there is limited research regarding the effectiveness of these strategies. The purpose of this study was to explore consumers' attitudes toward the lifestyle concept. Analyses of several consumer behavior variables and descriptors offered noteworthy findings for the home furnishings industry. This study found that although lifestyle orientation is a valuable tool for delineating consumer markets, these segmentations were not significant determinates of consumers' preference for elements of the lifestyle construct. Retailers and manufacturers are not simply creating home furnishing collections that target the needs of specific psychographic segment, but rather creating lifestyles being aspired to obtain. Although respondents scored the attitude variables neutral, the current market environment offers many examples of successfully home furnishing implementations of the lifestyle concept. These success stories coupled with additional findings indicate consumers' positive response to lifestyle merchandising.

Change of Condition: Women's Rhetorical Strategies on Marriage, 1710-1756 (open access)

Change of Condition: Women's Rhetorical Strategies on Marriage, 1710-1756

This dissertation examines ways in which women constructed and criticized matrimony both before and after their own marriages. Social historians have argued for the rise of companionacy in the eighteenth century without paying attention to women's accounts of the fears and uncertainties surrounding the prospect of marriage. I argue that having more latitude to choose a husband did not diminish the enormous impact that the choice would have on the rest of a woman's life; if anything, choice might increase that impact. Lady Mary Wortley Montagu, Hester Mulso Chapone, Mary Delany, and Eliza Haywood recorded their anxieties about and their criticisms of marriage in public and private writings from the early years of the century into the 1750s. They often elide their own complex backgrounds in favor of generalized policy statements on what constitutes a good marriage. These women promote an ideal of marriage based on respect and similarity of character, suggesting that friendship is more honest, and durable than romantic love. This definition of ideal marriage enables these women to argue for more egalitarian marital relationships without overtly calling for a change in the wife's traditional role. The advancement of this ideal of companionacy gave women a means of …

Microsatellite-based genetic profiling for the management of wild and captive flamingo populations. (open access)

Microsatellite-based genetic profiling for the management of wild and captive flamingo populations.

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

Indentation induced deformation in metallic materials. (open access)

Indentation induced deformation in metallic materials.

Nanoindentation has brought in many features of research over the past decade. This novel technique is capable of producing insights into the small ranges of deformation. This special point has brought a lot of focus in understanding the deformation behavior under the indenter. Nickel, iron, tungsten and copper-niobium alloy system were considered for a surface deformation study. All the samples exhibited a spectrum of residual deformation. The change in behavior with indentation and the materials responses to deformation at low and high loads is addressed in this study. A study on indenter geometry, which has a huge influence on the contact area and subsequently the hardness and modulus value, has been attempted. Deformation mechanisms that govern the plastic flow in materials at low loads of indentation and their sensitivity to the rate of strain imparted has been studied. A transition to elastic, plastic kind of a tendency to an elasto-plastic tendency was seen with an increase in the strain rate. All samples exhibited the same kind of behavior and a special focus is drawn in comparing the FCC nickel with BCC tungsten and iron where the persistence of the elastic, plastic response was addressed. However there is no absolute reason …

A two-year college typology for the 21st century: Updating and utilizing the Katsinas-Lacey classification system.

This study had two primary purposes. The first goal was to bring the 1993/1996 Katsinas-Lacey two-year college classification system into the 21st century using data from the 2000 United States Census and the National Center for Education Statistics' Integrated Postsecondary Educational Data System (IPEDS) surveys for the 2000-2001 and 2001-2002 academic years. The second goal was to create a descriptive portrait of the universe of two-year, publicly controlled institutions that primarily offer the associate's degree mapped against the updated classification system and to describe and discern similarities and differences within this particular population by class and subclass in terms of multiple measurable characteristics for which IPEDS data were available. The study, based upon classification theory utilized in social science and management sciences - particularly the work of Bailey and McKelvey - assessed the efficacy of a number of other recent proposed community college classification systems, the original Katsinas-Lacey system and the revised version of Katsinas-Lacey created through the current research. It found both the original Katsinas-Lacey system and the revised version to meet the criteria for a well-made classification model.
