Sexual Orientation and the Advanced Placement Art History Survey (open access)

Sexual Orientation and the Advanced Placement Art History Survey

This two-part study included a content analysis of an AP art history text and a survey together with interviews with AP art history teachers that embraced both quantitative and qualitative research methodologies. The first phase of the study examined one of the more popular art history survey texts in the AP art history program, Gardner’s Art through the Ages, in terms of how inclusive it is in addressing issues of sexual orientation and, particularly, same-sex perspectives. In addition, the text was examined for evidence of sexual orientation ignored – particularly same-sex perspectives ignored and for heteronormative hegemonies. The second phase investigated the understandings and opinions of AP art history teachers toward the inclusion of sexual orientation and same-sex perspectives in their curriculums and classrooms. Recent recognition of gay, lesbian, and same-sex perspectives in the study of art history has challenged art educators and art historians to begin to consider opening up their curriculums and writings to include these perspectives. These ignored perspectives produce important understandings that enrich and deepen the discourse of art history. The inclusion of gay and lesbian content and same-sex perspectives to the study of AP art history, not only effectively serves the needs of AP art …

Motivating Pre-service Teachers to Incorporate Technology Into the Classroom (open access)

Motivating Pre-service Teachers to Incorporate Technology Into the Classroom

Technology integration into the classroom is a multi-faceted and complex topic. One factor that can have an effect on a teacher's incorporation of technology into their classroom is pre-service teacher technology training. In this research study the ARCS instructional design model was applied to a pre-service teacher technology course in the hopes of motivating course attendees to both learn about technology incorporation and to incorporate technology into their future classrooms. The ARCS instructional design model that relies on the motivational sub-components of attention, relevance, confidences, and satisfaction to develop instruction that motivates to students to learn course content and goals. This study analyzed a group of pre-service teachers enrolled in a university technology training course to determine if the redesign resulted in the desired outcomes. Pre-test and post-test data was collected using both quantitative and qualitative instruments to analyze the potential effect of the redesigned course.

Spatial Ability in Registered Nurses (open access)

Spatial Ability in Registered Nurses

Spatial ability is the skill associated with mental relations among objects, the process of maintaining the physical aspects of an object after mentally rotating it in space. Many studies report a strong association of spatial ability with success in various areas of health care, especially surgery, radiology and dentistry. To date, similar investigations in professional nursing could not be located. Registered nurses, employed in an acute care multi-hospital setting, were surveyed using the Shipley-2Block Pattern Test, the Group Embedded Figures Test, and a newly created test of general nursing knowledge. The sample size of 123 nurses was composed of 31 male nurses and 92 female nurses. Data was collected between May and August of 2013 and analyzed using R, version 2.15.2. The present study did not demonstrate a statistically significant effect for gender differences on two measures of spatial ability. However, Cohen’s d effect sizes for mean gender differences in the present study are consistent with prior studies. This may suggest the nursing profession is comparable with other professions where males perform higher than females on spatial ability. The present study should be considered an initial step toward evaluating the relevance of spatial ability in the performance of nursing care.

The Lexicographer's Daughter: A Memoir (open access)

The Lexicographer's Daughter: A Memoir

This creative nonfiction dissertation is a memoir of the author's search for the somewhat mysterious hidden past of her father, the lexicographer Charles J. Lovell, who died in 1960, when the author was nine. Her father's early death left the author with many unanswered questions about his past and his family and so she undertakes a search to answer, if possible, some of those questions. Her search takes her to Portland, Maine; New Bedford, Massachusetts; and Pasadena, California, where she tries to discover the facts and uncover the forces that shaped her father's life. Along the way, she realizes how profoundly his death affected and shaped her own life, contributing to the theme of loss that pervades the memoir. In addition, she begins to realize how much her mother, Dixie Hefley Lovell, whose significance she previously overlooked, shaped her life. Ultimately, she comes to understand and accept that some of her questions are unanswerable.

Exploring a Community Partnership: A Narrative Inquiry into the 2004-2006 Semester Programs Between Artpace San Antonio and Louis W. Fox Academic and Technical High School

This qualitative inquiry explores a community-based art partnership called the semester programs that took place between Artpace San Antonio and Louis W. Fox Academic and Technical High School from 2004 until 2006. This narrative inquiry used interviews with artists and former Fox Tech art students involved in our program, along with my teacher/ researcher reflections, to make meaning from the data. The artists involved in the semester programs were Gary Sweeney, Daniel Guerrero, David Jurist, and Ethel Shipton. Former students interviewed include Eloy McGarity, Rosa Leija, John Contreras, and Jennelle Gomez, while I, Maria Leake represent the voice of the art teacher. Our stories of experience were analyzed and connections between situated learning theory, creativity theories, community-based art education, and memory research were all recognized as being exhibited during our community partnership programs. There were seven patterns and themes that were noted as occurring within each semester program, as well as notable distinctions. The patterns and themes from the data analysis suggest that our community partnership reflected the following: learning and creative expression went beyond the individual; networks of support and communication were available to all participants; challenges were acknowledged; empathy between participants was an unintentional outcome; working together as …

Johannes Brahms's Ein deutsches Requiem: A Comparison of the Reduced Orchestration Techniques in Joachim Linckelmann's Chamber Ensemble Version to Brahms's Four-Hand Piano Version (open access)

Johannes Brahms's Ein deutsches Requiem: A Comparison of the Reduced Orchestration Techniques in Joachim Linckelmann's Chamber Ensemble Version to Brahms's Four-Hand Piano Version

Recognizing the challenges small groups have to program a major work, in 2010, Joachim Linckelmann created a chamber ensemble arrangement of Johannes Brahms's "Ein deutsches Requiem." In 1869, J.M. Reiter-Biedermann published Brahms's four-hand piano arrangement of "Ein deutsches Requiem." Brahms's arrangement serves as an excellent comparison to the chamber ensemble version by Linckelmann, since it can be assumed that Brahms chose to highlight and focus on the parts he deemed the most important. This study was a comparative analysis of the two arrangements and was completed in three stages. The first stage documented every significant change in Joachim Linckelmann's recent chamber arrangement. The second stage classified each change as either a reduction, reorganization, or elimination. The final stage of the analysis was to compare the choices made by Linckelmann to those made by Brahms. The results show that Linckelmann's choices for reduction, reorganization, and elimination closely align with those of Brahms. The only differences between the arrangements can be attributed to Linckelmann's focus on retaining the original orchestral timbre and Brahms's focus on providing the original vocal parts.

Measuring the Effectiveness of Transfer of Learning Constructs and Intent to Transfer in a Simulation-based Leadership Training Program (open access)

Measuring the Effectiveness of Transfer of Learning Constructs and Intent to Transfer in a Simulation-based Leadership Training Program

The purpose of business training programs is to improve performance, which improved performance changes leadership behaviors based on the knowledge, skills, and abilities (KSAs) learned in training. One of the most common criticisms of leadership training is the tendency to focus on teaching theory but not on applying theory into practice, that is, transfer of learning. Research usually ends at the point of identifying, describing, or measuring factors that influence transfer. Ongoing research must identify what constructs in the transfer of learning process should be effectively changed or managed. There is a gap in research on the degree to which performance improvement through KSAs learned in a simulation training program actually transfer to the work environment. Additional research is needed that examines the relationship between transfer of learning and intent to transfer, which are critical outcomes in the field of human resource management and development. The purpose of the study was to examine the relationship between intent to transfer and four constructs in the transfer of learning process during a simulation-based leadership training program. Participants completed self-report assessments that measured the relationships between intent to transfer and four constructs: ability, motivation, work environment, and learner readiness.

An Exploratory Study of the Impact of Institutional Policies and Practices of Community and Technical Colleges in Texas on Student Persistence in Online Courses

Online education is the fastest growing form of course delivery of higher education in the United States. It has revolutionized how students and instructors interact in the educational process. Yet students in online courses continue to experience higher attrition rates than their counterparts in traditional face-to-face classes despite the advantages offered by the technology. This study examined the impact that institutional policies and practices at community colleges in the state of Texas have had on student persistence in online courses. It also examined how institutions collect and use data in addressing students' attrition. The findings were used to identify the most effective institutional practices to share with community college systems in Texas in an effort to improve student persistence in online courses across the state. The population for the study consisted of the 50 public two-year community college and the technical college systems in the state of Texas. The study used a mixed method. A theoretical model of institutional impact on online persistence was drawn from the literature review. This model's five categories were then used to construct a survey to collect data on institutional practices and measure the effectiveness in addressing student persistence. Four college systems were identified using …

How Attitudes towards Statistics Courses and the Field of Statistics Predicts Statistics Anxiety among Undergraduate Social Science Majors: A Validation of the Statistical Anxiety Scale

The aim of this study was to validate an instrument that can be used by instructors or social scientist who are interested in evaluating statistics anxiety. The psychometric properties of the English version of the Statistical Anxiety Scale (SAS) was examined through a confirmatory factor analysis of scores from a sample of 323 undergraduate social science majors enrolled in colleges and universities in the United States. In previous studies, the psychometric properties of the Spanish and Italian versions of the SAS were validated; however, the English version of the SAS had never been assessed. Inconsistent with previous studies, scores on the English version of the SAS did not produce psychometrically acceptable values of validity. However, the results of this study suggested the potential value of a revised two-factor model SAS to measure statistics anxiety. Additionally, the Attitudes Towards Statistics (ATS) scale was used to examine the convergent and discriminant validities of the two-factor SAS. As expected, the correlation between the two factors of the SAS and the two factors of the ATS uncovered a moderately negative correlation between examination anxiety and attitudes towards the course. Additionally, the results of a structural regression model of attitudes towards statistics as a predictor …

As the Need Presents Itself: Social Identity Theory and Signaling in Online Crowdfunding Campaigns (open access)

As the Need Presents Itself: Social Identity Theory and Signaling in Online Crowdfunding Campaigns

As social interactions increasingly become exclusively online, there is a need for research on the role of identity and social identity in online platforms. Drawing on Symbolic Interactionist approaches to identity, namely Social Identity Theory and Identity Theory, as well as Signaling Theory, this study argues that actors will selectively use religious language to signal their credentials to an audience for the purpose of garnering prosocial behavior in the form of donations to their fundraising campaign. Using latent semantic analysis topic models to analyze the self-presentations of crowdsourcing campaigners on GoFundMe.com, this study found evidence for the presence of signaling to a religious identity online as well as a significant difference in the presentation of need for campaigns originating in areas with high reported religiosity compared to campaigns from areas of low religiosity. In comparison to other campaigns, campaigners engaging in religious signaling were significantly increasing their donations. I suggest that strategically chosen religious topics in online crowdfunding is an example of low-cost identity signaling and provides insight into how signaling happens online and the potential outcomes resulting from this cultural work.

Testing a Comprehensive Model of Muscle Dysmorphia Symptomatology in a Nonclinical Sample of Men

As increasing emphases are placed on the importance of a muscular male physique in Westernized culture, more men are experiencing eating, exercise, and body image (EEBI) disturbances. Clinician-researchers have identified a syndrome, termed muscle dysmorphia (MD), in which individuals, usually men, are pathologically preoccupied with their perceived lack of muscularity. The current study tested a modified version of an extant theoretical model of MD symptomatology as well as an alternative model of MD symptomatology. Over 700 adult men completed a demographic questionnaire, a symptom inventory, a self-esteem questionnaire, a measure of perfectionism, a measure of the media’s influence on EEBI disturbances, and measures of body dissatisfaction and MD symptoms. Structural equation modeling (SEM) was used to examine the goodness of fit of the proposed models. Overall, the first model demonstrated poor fit with the data. Conversely, the alternative model fit the data adequately. The alternative model was cross validated with a second sample, and also fit this data adequately.

Preschool Teachers' Self-reported Levels of Preparation for Classroom Behavior Management

Research indicates that serious behavior problems begin during the early childhood years. The study examined the perceived preparedness of teachers related to behavior management as well as preschool teachers' usage of evidence-based prevention and intervention strategies. The data indicates that preschool teachers feel prepared for managing aggression in their classrooms and report utilizing evidence-based prevention and intervention strategies regularly. Additionally, the data shows a weak relationship between teacher variables and the likelihood of feeling prepared for managing aggression or utilizing evidence-based strategies. The results can be used to gain a better understanding of special education preschool teachers' training needs in regard to behavior management and managing behavior problems in the preschool classroom.

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress (open access)

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress

The activity of plant 9-lipoxygenases (LOXs) influences the outcome of Arabidopsis thaliana interaction with pathogen and insects. Evidence provided here indicates that in Arabidopsis, 9-LOXs facilitate infestation by Myzus persicae, commonly known as the green peach aphid (GPA), a sap-sucking insect, and infection by the fungal pathogen Fusarium graminearum. in comparison to the wild-type plant, lox5 mutants, which are deficient in a 9-lipoxygenase, GPA population was smaller and the insect spent less time feeding from sieve elements and xylem, thus resulting in reduced water content and fecundity of GPA. LOX5 expression is induced rapidly in roots of GPA-infested plants. This increase in LOX5 expression is paralleled by an increase in LOX5-synthesized oxylipins in the root and petiole exudates of GPA-infested plants. Micrografting experiments demonstrated that GPA population size was smaller on plants in which the roots were of the lox5 mutant genotype. Exogenous treatment of lox5 mutant roots with 9-hydroxyoctadecanoic acid restored water content and population size of GPA on lox5 mutants. Together, these results suggest that LOX5 genotype in roots is critical for facilitating insect infestation of Arabidopsis. in Arabidopsis, 9-LOX function is also required for facilitating infection by F. graminearum, which is a leading cause of Fusarium head …

Toward a Rationale for Music Education in the Public School Context Framed with both Progressive and Essentialist Considerations: Operationalizing the Ideas of William Chandler Bagley

In music education, aesthetic education and praxial music education serve as two major, guiding philosophical frameworks, yet supporters of each often conflict with one another. Furthermore, both are slightly problematic with respect to the specific context of the public school. Each framework is primarily music-based, however, music education has existed in the wider context of general education since the 1830s. Given the recent core-status designation for music education, as part of all fine arts, in the reauthorization of the Elementary and Secondary Education Act, a framework from general education that supported music education could offer benefits for the domain. However, the wider context of general education is messy as well. Two groups occupy most of the space there, and remain locked in a fundamental disagreement over the purpose of a formal education. The progressive educators, historically framed by Dewey and Thorndike, contend that education functions as societal improvement. In contrast, the essentialists contend that education functions as cultural transmission. Therefore, a more specific need for music education involves selecting a framework from general education that resolves this conflict. The writings of William Chandler Bagley indicate that he balanced both considerations of a formal education while also advancing his notion of …

Exploring Teachers’ Constructivist Beliefs Using Talis 2013: Approaches to Training and Development

The changing landscape of demographics, technology, and diversity in the learning environment is challenging schools around the world to rethink their approaches to the implementation of high-quality teaching practices. Classroom practices are becoming more complex because educators have to ensure that their students are well-equipped with 21st century skills (e.g., Darling-Hammond, 2010; Dede, 2010; Griffin, McGaw, & Care, 2012). Educators, curriculum developers, and school administrators need to be more than experts in pedagogy. They are now required to keep up with current ideas, innovative instructional practices, and the results of a variety of educational reform efforts. Believing that teachers’ beliefs are the most important psychological construct with regard to instructional practices (Pajares, 1992) and that teachers’ beliefs are related to their choice of classroom practices and, ultimately, the students’ performance (Bybee, Taylor, Gardner, Van Scotter, Powell, Westbrook, & Landes, 2006; Staub & Stern, 2002), the author of this study utilizes the international data set of the Teaching and Learning International Study (TALIS) 2013 to examine the associations between teachers’ constructivist beliefs, their self-efficacy beliefs, professional activities, and the school principals’ instructional leadership as related to lower secondary school teachers and principals in South Korea, Finland, and Mexico.

Resistance Exercise and Alcohol: Combined Effects on Physiology and Performance (open access)

Resistance Exercise and Alcohol: Combined Effects on Physiology and Performance

Resistance exercise (RE) training is a well-known and effective method for promoting increases in muscle mass and strength. A single bout of RE induces physiological disturbances that require coordinated activation of the immune system and intramuscular signaling in order to return the tissue to homeostasis and adapt to the RE challenge. On the other hand, acute binge alcohol consumption can affect the immune response to an inflammatory challenge, intramuscular anabolic signaling, and muscle protein synthesis, and the effects of alcohol on these processes are opposite that of RE. Furthermore, individuals who report more frequent exercise also report a greater frequency of binge drinking. However, few investigations exist regarding the effects of binge alcohol consumed after a bout of RE on RE-induced physiological changes and performance recovery. Therefore, the overarching purpose of the investigations contained within this dissertation was to investigate the effect of alcohol consumed after RE on the RE-induced changes in mTOR pathway signaling, muscle protein synthesis, inflammatory capacity, strength recovery, and power recovery. Although RE increased mTOR pathway signaling and inflammatory capacity after exercise and reduced maximal strength and explosive power the day after exercise, we observed no effects of alcohol (1.09 g ethanol∙kg-1 lean body mass, designed …

Stereotypical Science: Exploring High School Occupational Preferences for Science by Sex, Personality, and Cognitive Ability (open access)

Stereotypical Science: Exploring High School Occupational Preferences for Science by Sex, Personality, and Cognitive Ability

Circumscription and Compromise theory suggests self-concept and sex stereotype explain occupational preferences, including preferences for science, technology, engineering and mathematics (STEM). Support exists for sex differences between males and females in both science degrees and science careers. The main thrust of observed sex differences in science lies in the development of occupational interest, as it has been suggested females are encouraged away from science due to stereotypes and social pressure. The present study evaluates high school juniors and seniors (n = 295) to explore their preference for science as indicated by science motivation, attitude, academic experience, and interest. Latent Profile Analysis was used to model profiles of preferences for science with a person-centered approach. Then, the impact of self-concept variables was explored and four profiles of science interest were identified. Sex differences were identified based on science interest, but were not always in favor of males. Covariate analysis indicates vocabulary ability and personality as significantly different for students in the high science interest profile. Implications of these results and future research directions are discussed.

Differentiation: A Taxonomy of Online Learner Types in Higher Education (open access)

Differentiation: A Taxonomy of Online Learner Types in Higher Education

Online learning is no longer considered novel within higher education. It has emerged as an accepted distinct channel and environment for instructional engagement. There is a notable deficit of works and theoretical constructs specifically addressing the identification and differentiation of online learner types and examining them as a distinct system within the learning environment. Learning effectiveness within an online instructional environment is affected by the individual student engaged in the instruction. The instructional experience of the learner is determined by their individual perceptions of and reactions to both internal and external factors. Therefore, it is critical to address the online learner holistically as a stand-alone systemic dimension of the online learning environment to truly understand their differentiating behaviors, motives, characteristics, and dynamics. The study classified and articulated the distinctive types of learners engaged in online instruction within the higher education context based on the key dynamics, factors, and influencers of the individual in order to provide a more comprehensive understanding of the individuals engaged in learning. Additionally, the study generated a new theoretical model, the taxonomy of online learner types (TOLT) to provide unique insights into the different types of learners and serve as an essential step towards developing awareness …

A Randomized Clinical trial of Cognitive-Behavioral Therapy for Insomnia in a College Student Population

Nearly 10% of college students experience chronic insomnia. Cognitive-behavioral therapy for insomnia (CBTi) is an empirically validated multi-component treatment that has been demonstrated to produce reliable and durable benefits in the general adult population. However, there have been no studies examining the effectiveness of multi-component CBTi in a college student population, even though many studies have examined the efficacy of single treatment modalities. These young adults are different from the general adult population because they are in a unique transitional developmental phase as they are maturing from adolescence into adulthood, they are sleepier than adults, they tend to have irregular sleep schedules, and their living situations are often different from the general adult population. In this study college students with chronic insomnia were randomly assigned to either six sessions of CBTi or a wait list control (WLC) group. All participants completed sleep diaries, sleep measures, and psychosocial measures. The results indicated students who received CBTi showed improvements in sleep efficiency (SE), sleep onset latency (SOL), number of awakenings (NWAK), time awake after sleep onset (WASO), and sleep quality (SQ). They also had decreased insomnia severity (ISI), dysfunctional beliefs about sleep (DBAS), and general fatigue (MFI), as well as increases in …

Retention: Course Completion Rates in Online Distance Learning

Online courses in higher education have a reputation for having a lower course completion or retention rate than face-to-face courses. Much of this reputation is based upon anecdotal evidence, is outdated, or is on a small scale, such as a comparison of individual courses or programs of instruction. A causal-comparative analysis was conducted among 11 large, high research public universities. The universities were compared to each other to determine if differences existed between online and face-to-face course completion; undergraduate and graduation online course completion was analyzed for differences as well. The findings suggested the magnitude of the differences between online and face-to-face completions rates was small or negligible. The area which showed a higher magnitude of difference was in the comparison between undergraduate and graduate online course completion; the practical significance could be worth considering for educational purposes.
