This study investigated the relationship between belief in coaching abilities (coaching efficacy beliefs, CEB), transformational leadership behaviors (TLB), and motivational climate development of current strength and conditioning coaches working with high school level athletes. The measures used were the coaching efficacy scale for high school teams (CES II-HST, Myers et al.,2000), the differentiated transformational leadership inventory (DTLI, Callow et al., 2009), and the patterns of adaptive learning scales (PALS, Midgley et al., 2000). It was hypothesized that CEB and TLB would influence motivational climate development, while coaches' background characteristics would correlate with CEB, TLB, and motivational climate development. The 60 coaches who participated reported an average of thirteen (SD=8) years of experience and 51 were Certified Strength and Conditioning Specialists. Coaches reported high efficacy, frequent use of TLB, and development of a moderately high task- and somewhat ego-involving motivational climate. Correlations between demographic variables and CEB, TLB, and motivational climate development revealed three significant relationships: years of experience with CEB, and professional development activities and athlete to coach ratio with ego-involving climate development. CEB and TLB had a strong positive correlation. Two regression analyses were conducted to determine if the outcomes of the CEB and TLB measures predicted motivational climate …

Faced with the challenges to addressing the novelties of the changing business environments (e.g., new customer requirement, changes in customers taste and preferences, the introduction of new products or services by competitors), organizations seek to build collaboration among their employees who possess complementary knowledge. Integrating complementary knowledge enhances employees' ability to address environmental challenges and foster innovation. Despite the importance of knowledge integration for innovation, integration of such knowledge becomes difficult when employees lack a shared understanding of knowledge, and when the knowledge is newly generated. Because new knowledge is tacit in nature and highly personal to a particular individual, it is difficult to articulate, making knowledge integration (KI) an arduous task. Lack of shared understanding, the presence of new knowledge, and lack of common interests in employees creates three types of knowledge boundaries – syntactic (information processing) boundaries, semantic (interpretive) boundaries, and pragmatic (political) boundaries. The presence of knowledge boundaries makes it difficult for employees to share and access their knowledge with each other. To overcome the challenges related to the knowledge boundaries, employees use boundary-spanning objects, which are common lexicons, common meaning, and common interests, to share and access their knowledge across the boundaries. Although prior studies have …

This study examined the effects of fluency-based instruction on the identification of six component-composite relations for early reading skills. Five participants (ages 5-8) who struggled with reading participated. A multiple probe design was used to assess the effects of frequency building on prerequisite skills on the emergence of composite reading skills. The results show that the prerequisite skills taught did not have an effect on the composite skill probes but did have an effect on the assessment scores. The data expand the research pertaining to Precision Teaching, fluency-based instruction, and component-composite relations. These data suggest that additional skills may be needed to be taught in order to effects on the composite skills. In addition, these authors identify the need for the identification of the component skills necessary to teach rapid autonomic naming.

Custodial grandmothers and grandchild (aged 4 to 12) dyads (N = 170) completed self-report, other-report, and an observational task that captured child HI, expressive social support, and custodial grandmother-grandchild compliance variables. A multivariate analysis of covariance tested differences between high and low hyperactivity-inattention on observed parenting variables while controlling for child age. While overall results were not significant, there were significant differences between child age and observed parenting variables. A hierarchical regression model revealed that, when controlling for age, child hyperactivity-inattention does not moderate the relationship between commands given by a custodial grandmother and child compliance, but revealed that direct commands from the grandmother predicted compliance. A second hierarchical regression model suggested that encouragement and praise (versus criticism and discouragement) from a grandmother moderated the relationship between grandmother commands and child compliance, when controlling for child age. It appeared that when grandmothers gave indirect commands more frequently, encouragement and praise instead of criticism was associated with greater compliance. In dyads with frequent direct commands given, compliance was high, however dyads who scored high in direct commands with criticism and discouragement were most likely to comply. This study adds to the literature by providing insight into the challenges and strengths for …

The purpose of the study was to investigate how the online, computer-based learner's personal learning profile (Preference), the content delivery method supplemented with visual content based on Neil Fleming's VARK (visual, aural, read/write, kinesthetic) model (Content), and the interaction of Preference and Content, influenced learner performance (Performance) and/or learner self-reported satisfaction (Satisfaction). Participants were drawn from a population of undergraduates enrolled in a large public southwestern research university during the fall 2015 semester. The 165 student participants (13.79% completion rate) were comprised of 52 (31.5%) females and 113 (68.5%) males age 18-58+ years with 126 (76.4%) age 18-24 years. For race/ethnicity, participants self-identified as 1 (0.66%) American Indian/Alaska Native, 21 (12.7%) Asian/Pacific Islander, 27 (16.4%) Black, non-Hispanic, 28 (17%) Hispanic, 78 (47.3%) White, non-Hispanic, 10 (6.1%) other. Reported socioeconomic status was 22 (13.3%) withheld, 53 (32.1%) did not know, 45 (27.3%) low, 13 (7.9%) moderately low, 16 (9.7%) middle, 8 (4.8%) upper middle, and 8 (4.8%) upper. This causal-comparative and quasi-experimental, mixed-method, longitudinal study used researcher-developed web-based modules to measure Performance and Satisfaction, and used the criterion p < .05 for statistical significance. A two-way, 4 x 3 repeated measures (Time) analysis of variance (RM-ANOVA) using Preference and Content was …

Data-driven decision making is an integral part of higher education and it needs to be rooted in strong methodological and statistical practices. Key practices include the use and interpretation of effect sizes as well as a correct understanding of null hypothesis significance testing (NHST). Therefore, effect size reporting and interpreting practices in higher education journal articles represent an important area of inquiry. This study examined effect size reporting and interpretation practices of published quantitative studies in three core higher education journals: Journal of Higher Education, Review of Higher Education, and Research in Higher Education. The review covered a three-year publication period between 2013 and 2015. Over the three-year span, a total of 249 articles were published by the three journals. The number of articles published across the three years did not vary appreciably. The majority of studies employed quantitative methods (71.1%), about a quarter of them used qualitative methods (25.7%), and the remaining 3.2% used mixed methods. Seventy-three studies were removed from further analysis because they did not feature any quantitative analyses. The remaining 176 quantitative articles represented the sample pool. Overall, 52.8% of the 176 studies in the final analysis reported effect size measures as part of their major …

This collective case study explores the confluence of educational policy and professional praxis by examining the ways art teachers in one public school district make decisions about creating and implementing curricula. Through various interpretations of one district's formal and informal expectations of art teachers, some of the complexities of standards, instruction, and assessment policies in public schools are described. The research shares how art teachers are influenced by local policy expectations by examining how five K-12 art teacher participants negotiate their ideological beliefs and practical knowledge within the professional context of their local setting, and presents an art teacher decision-making framework to conceptualize the influences for praxis and to organize analysis. Case study data include in-depth interview sessions, teaching observations, and district policy artifacts. Themes emerge in the findings through coding processes and constructivist grounded theory analysis methods. The research describes how participants interpret and negotiate expectations, finding curricular freedom and participation in public exhibition as central policy factors. Contributing the perspectives of art teachers to the literature of policy implementation and fine arts education, the study finds that balancing autonomy and mandates are primary sites for negotiating praxis and that informal expectations for student exhibition contribute to a culture …

Invasive woody shrubs are a problem when they displace native species and threaten habitats, especially those that harbor rare or endangered species. They not only compete with native plants, but also alter habitat and food that many organisms depend upon. Invasive plants undergo a release from their specialist predators in the nonnative range, providing them advantages over native species. Because modes and pathways of how invasive species spread are not fully understood, predicting spread and implementing restoration ecological controls remain inexact. Due to the lack of comparative studies on woody shrubs, especially invasive privets, we understand very little about conditions affecting their invasiveness. A study was conducted near Dallas, Texas to determine if privet has allelopathic properties that influences growth of native plants. Soil nutrients and other analyses were made and compared between field plots supporting privet, plots in which privet has been removed, and plots where privet has not been observed. In some field plots, natives were planted under the three previously mentioned conditions, and their survival and condition were monitored to evaluate effects of privet on their establishment and growth. It was found that Chinese privet did hinder seed germination in red mulberry, soapberry and beautyberry and root …

Despite an increasing demand for college graduates skilled in science, technology, engineering, and mathematics ("STEM") fields, a substantial number of students who choose these majors leave after taking their first-year "gateway" math and science coursework. Research has shown GPA to be a salient predictor of persistence in STEM majors: Students who earn high grades in gateway courses are more likely to continue, and those who earn low grades are more likely to leave. However, a small number of students defy that expectation: Despite a low gateway course GPA, they persist not just to the sophomore year but all the way to graduation. The purpose of this study was to determine what other experiences, motivations, or attributes aside from academic performance influence these students to persist. A qualitative approach was taken with the use of semi-structured interviews, which provided a means for analysis based on insights directly from students. An invitation was sent to a cohort of graduating math and science majors at a large public institution, and 10 eligible volunteers were chosen to participate. A thematic analysis was conducted to seek common themes in the students' interviews regarding their experiences in their gateway coursework, their feelings towards their chosen major, …

The purpose of this study is to evaluate the potential benefit of two hours of activities involving 2D and 3D fabricators on the spatial reasoning skills of children in Grades 4 and 5, ages 9 to 10, from a private school in Southeast Texas. Can the introduction to hands-on activities with products created with these devices and learning about how these devices operate improve spatial reasoning skills? The research also evaluates the use of the Shapes Test as a valid measure of the spatial reasoning skills of children. The Cube Design and Spatial Memory subtests of the UNIT (Universal Nonverbal Intelligence Tests) were used for evaluating the spatial reasoning skills of the participants, based on their respected validity, along with a Shapes Test that is in development. Discussion regarding gender, language, and experiential theories of spatial reasoning skill development are included in the literature review.

Artie Shaw's Interlude in B-flat is unknown to many in the classical clarinet world and remains unperformed by clarinetists, despite its historical importance as one of the earliest Third Stream compositions, the earliest composition of its type in the clarinet repertoire. This prompts the question, why? This document explores four possible reasons for the marginalization of Interlude in B-flat. First, Shaw's historical narrative typically places him within the jazz world and not the classical world. Classical clarinetists may assume a Shaw composition will require a jazz background and experience beyond their abilities, namely improvisation. Second, the instrumentation, string quartet plus jazz combo, is atypical, making it difficult to program. Third, jazz and classical educational worlds do not necessarily overlap or interact, and neither has taken ownership of this Third Stream composition. Lastly, manuscripts, recordings, and other materials for Interlude in B-flat are limited and not readily available. Because Artie Shaw is not only a significant American clarinetist but also an important composer within the Third Stream narrative, Interlude in B-flat should be known and performed. This project aimed to promote the understanding and accessibility of this important and unknown composition to the classical clarinet world by providing an accessible arrangement …

The worldwide rise of diabetes and obesity has spurred research investigating the molecular mechanisms that mediate the deleterious effects associated with these diseases. Individuals with diabetes and/or obesity are at increased risk from a variety of health consequences, including heart attack, stroke and peripheral vascular disease; all of these complications have oxygen deprivation as the central component of their pathology. The nematode Caenorhabditis elegans has been established as a model system for understanding the genetic and molecular regulation of oxygen deprivation response, and in recent years methods have been developed to study the effects of excess glucose and altered lipid homeostasis. Using C. elegans, I investigated transcriptomic profiles of wild-type and hyl-2(tm2031) ( a ceramide biosynthesis mutant) animals fed a standard or a glucose supplemented diet. I then completed a pilot RNAi screen of differentially regulated genes and found that genes involved in the endobiotic detoxification pathway (ugt-63 and cyp-25A1) modulate anoxia response. I then used a lipidomic approach to determine whether glucose feeding or mutations in the ceramide biosynthesis pathway or the insulin-like signaling pathway impact lipid profiles. I found that gluocose alters the lipid profile of daf-2(e1370) (an insulin-like receptor mutant) animals. These studies indicate that a transcriptomic …

Across medieval Europe, the pilgrimage route to Santiago de Compostela in Spain traced a lattice web of popular culture. From the lowest peasant to the greatest king and churchmen, the devout walked pathways that created an economy and contributed to a social and political climate of change. Central to this impulse of piety and wanderlust was the veneration of the Virgin Mary. She was, however, not the iconic Mother of the New Testament whose character, actions, and very name are nearly absent from that first-century compilation of texts. As characterized in the words of popular songs and tales, the mariales, she was a robust saint who performed acts of healing that exceeded those miracles of Jesus described in the Bible. Unafraid and authoritative, she confronted demons and provided judgement that reached beyond the understanding and mercy of medieval codes of law. Holding out the promise of protection from physical and spiritual harm, she attracted denizens of admirers who included poets, minstrels, and troubadours like Nigel of Canterbury, John of Garland, Gonzalo de Berceo, and Gautier de Coinci. They popularized her cult across Europe; pilgrims sang their songs and celebrated the new attributes of Mary. This dissertation uses the greatest collection …
