Examination of the Effects of Experience and Missing Information on Tax Preparer Judgment
This research examines how experience and missing information affect judgments of tax return preparers. Tax return preparers may often be faced with the problem of incomplete information, and their responses to this problem may be conditioned by whether or not they recognize information is missing. Based on the Holland et al.'s cognitive theory of induction as applied to tax judgment by Marchant et al., it was hypothesized that experienced tax preparers would correctly classify more items as to their relevance to a specific tax issue than novice tax preparers. Additionally, it was hypothesized that the strength of recommendations of tax preparers who had no relevant information missing would be greater than the strength of recommendations of tax preparers who had relevant information missing and were prompted that information was missing. Lastly, it was hypothesized that prompting that relevant information was missing would have a greater effect on the strength of recommendations of tax return preparers with lesser specific experience than it would on the strength of recommendations of tax return preparers with greater specific experience. The results suggest that experienced tax preparers do recognize the relevance of information to a greater degree than novice tax preparers. There was no significant difference, however, in the strengths of recommendation of tax preparers who had no missing information and those who were prompted that information was missing. There was a significant difference in the strengths of recommendations of tax preparers with lesser specific experience who had been prompted that relevant information was missing and those who had not been prompted that relevant information was missing. Among tax preparers with greater specific experience, however, there was no significant difference between the two groups. These results suggest that tax preparers with greater specific experience recognized that relevant information was missing without being prompted, while tax return preparers with lesser specific experience did not.
An examination of the factors that influence an auditor's decision to use a decision aid in their assessment of management fraud.
In recent years, the accounting profession has faced increased scrutiny because of scandals involving management fraud (e.g., Enron, WorldCom). In response, Statement on Auditing Standards (SAS) #99 has expanded auditors' responsibility for detecting fraud, requiring auditors to gather significantly more information in their assessment of fraud. In addition, the Public Company Accounting Oversight Board (PCAOB) will focus on fraud detection through their inspections of registered accounting firms. In light of the increased emphasis on auditors' responsibility for detecting fraud, public accounting firms face the challenge of improving their fraud detection process, including their assessment of management fraud risk. Decision aids are one way for auditors to improve their assessment of management fraud risk. In fact, several studies from the decision aid literature suggest that aids are useful tools for a variety of tasks, including fraud risk assessment. At the same time, another stream of the decision aid reliance literature, which looks at people's willingness to rely on decision aids, suggests that individuals tend to be reluctant to accept the output given by an aid. Thus, the primary focus of this paper is on uncovering factors that would encourage one to voluntarily use and rely upon a decision aid. Toward that end, 132 senior-level auditors participated in an experiment that examined how several factors (confidence, perceived usefulness, client size, and conformity pressure) affect decision aid usage and reliance. The results show that perceived usefulness and decision aid reliance are significantly related. Further, the results suggest that perceived usefulness affects reliance more than variables examined in prior studies (e.g., confidence). Finally, the results suggest that decision aid usage mediates the relationship between perceived usefulness and reliance. The results of the current study have important implications for research in both the information systems and decision aid reliance areas. First, the study shows that perceived usefulness, a significant construct from the technology acceptance model (TAM) literature, is also a significant factor in determining decision aid usage and reliance. Second, the study further delineates how certain factors affect decision aid reliance.
An Examination of the Feasibility of Measuring National Income from Monetary Data
The purpose of the paper is to explore, more fully, one particular aspect of economic accounting, measurement of national income. Since data problems often inhibit attempts to measure national income by conventional methods, particularly in less developed regions, the paper focuses attention on alternative techniques of measurement with major emphasis on procedures employing monetary data.

An examination of the influence of selected works of Franz Schmidt on the Concerto for Trumpet and Orchestra and the Sonata for Trumpet and Piano by Karl Pilss.
The Concerto for Trumpet and Orchestra and the Sonata for Trumpet and Piano by Karl Pilss were written in 1934 and 1935, respectively. They are examples for solo trumpet of the late German Romantic style of melody, harmony, form and structure. Musicians and audience often overlook composer Karl Pilss outside his native Vienna. His ties to the Trompeterchor der Stadt Wien and the National Socialist Party during the years preceding the Second World War have limited widespread acceptance of this composer. Pilss' output includes concertos for trumpet, horn, bass trombone, and piano, sonatas for trumpet, violin, and oboe, wind quintets and octets, piano pieces, choral works, and numerous large and small brass works. Pilss' teacher Franz Schmidt is more widely known. His four symphonies provide examples of post-Romanticism at the beginning of the twentieth century. His characteristic use of melody, harmony, form and structure is in the mold of Richard Strauss. Schmidt did not write any works for solo trumpet. However, his Symphony No. 4 begins and ends with extended passages for solo trumpet. Pilss inherited and adopted many of Schmidt's melodic, harmonic and formal traits. These can be clearly heard in his Concerto for Trumpet and Orchestra and the Sonata for Trumpet and Piano. This work discusses in detail the musical and compositional connection between Karl Pilss and his teacher, Franz Schmidt. Musical elements of melody, harmony, form and structure are used to illustrate the close connection between pupil and mentor. The use of the characteristic "Schmidt chord" in Pilss' works cements the link between the two composers. The Concerto for Trumpet and Orchestra and the Sonata for Trumpet and Piano deserve wider acceptance on the basis of their musical merit and as unique examples of the late German Romantic style for solo trumpet.
An Examination of the Nature of a Problematic Consumer Behavior : Compulsive Purchasing as a Learned Adaptive Response, Addiction, and Personality Disorder
The problem examined in this study was the nature of compulsive purchasing behavior. Three proposed models depicting this behavior as a learned adaptive response to anxiety and/or depression, an addiction, and a personality disorder were introduced and discussed in Chapter I. Background information concerning the areas examined in the models was presented in Chapter II. The research methodology was discussed in Chapter III and the findings of the research presented in Chapter IV. A summary, conclusions, implications, and recommendations were presented in Chapter V.
An Examination of the Perceptual Asymmetries of Depressed Persons as Mediated by Hypnosis
This study evaluated the role of asymmetric processing of information in depression. Depression has been hypothesized to involve a deficit in the global processing of information (Tucker, 1982). This type of global processing has been manipulated through the use of hypnosis by Crawford and Allen (1983). In the current study, a 3 x 2 ANCOVA design allowed the comparison of three groups of subjects on their performance on a perceptual task measuring global perception. The task chosen was designed by Navon (1977) and consisted of designs which differed on global or local features. The groups were screened with the Beck Depression Inventory, the Harvard Group Scale of Hypnotic Susceptibility, and the Edinburgh Handedness Inventory, yielding 46 subjects divided into three groups of right-handed males and females. The experimental group consisted of high susceptible depressives from the community. The controls were one group of high susceptible normals and one of low susceptible depressives. All groups performed the Navon task under both waking and hypnosis conditions. Analysis of the results revealed a main effect for group (F(2, 86) = 9.60, p < .01) on the global scores. In addition, high social desirability scores predicted slower presentation times. However, hypnosis was not effective in creating a significant change in performance on the dependent measure. The results are discussed as support for the hypothesized differences between depressives and normals. Differences between the measures used in the present study and that of Crawford and Allen suggest that hypnosis may mediate imagery at a conceptual level but not at the level of the primary visual-perceptual system.
An Examination of the Percussion Writing in the Chamber Works of George Crumb, 1960-1980 with Three Recitals of Selected Works of Bergsma, Kurka, Miyoshi, Niimi, Takemitsu, and Others
In this study, the unique style of percussion writing in the chamber works of George Crumb, written between 1960 and 1980, is examined. The principal aspects examined within this study include: the extended instrumental techniques, the use of percussion within the musical imagery, soloistic treatment, compositional and notational procedures, and specific performance problems pertaining to the chamber work Songs, Drones, and Refrains of Death.
An Examination of the Presence of Schön's Concept of "Reflective Conversation" as a Defining Component in the Applied Studio Music Lesson
The purpose of this study was to examine the presence of Schön's concept of reflective conversation as a defining component in the applied studio music lesson. The research problems were (1) to determine the presence of complete and incomplete reflective conversations; (2) to determine the verbally exhibited knowledge base within complete conversations in relationship to conversation length; and (3) to establish an instructional profile of stable behaviors based on reflective conversation as a distinguishing characteristic among selected teachers. Videotapes of twenty-six applied studio music lessons of thirteen university teachers were analyzed according to problem solving, on-the-spot experimentation, and evaluation. An observation form was developed and was a reliable tool to collect information concerning number and type of reflective conversations, conversation length, and the teachers' verbally demonstrated knowledge base. Knowledge base was obtained by using the procedural model of Flanagan's critical incident technique. Reflective conversations existed and were a distinguishing characteristic of the teachers. With the exception of two teachers, a stable use of both number and length of reflective conversations, and knowledge base areas, was found. A discernible difference in the teachers' knowledge base within conversation length existed, and thus established instructional profiles for the teachers. Complete reflective conversations ranged from one-sixth to over half of total lesson time. Within instrument categories, teachers generally revealed a dissimilar knowledge usage. Some teachers exhibited fast-paced problem solving, in one minute or less, and named one or two knowledge areas. Others had longer conversations, up to five minutes, with more deliberate problem solving, and as many as twelve knowledge areas named. Results indicated that a practically significant situation can be examined by establishing teacher instructional profiles based upon reflective conversation. Methods employed in this study could be used to document teacher problem-solving and teacher knowledge in a variety of settings.
Examination of the Relationship Between Glucuronic Acid and Vascular Damage in Rats
The goal of this experiment was to examine the role of glucuronic acid in the development of vascular damage in the kidneys and retinas of diabetic individuals. Glucuronic acid was provided to rats in their water at various concentrations in order to increase plasma levels of the compound. Kidneys and retinas were excised and compared to control specimens using microscopy to determine the effect of elevated blood glucuronic acid levels on the occurrence of microaneurysms in renal capillary networks. No differences were seen between the treatment and control groups. Further study needs to be conducted to determine a more suitable time frame for this experiment.

An Examination of the Relationship Between Published Book Reviews and the Circulation of Books at an Academic Library
The primary purpose of this study was to determine if book reviews are useful and significant indicators of potential circulation. Major book reviewing sources were studied to determine if some were more useful than others in selecting books which circulate.
An Examination of the Relationship Between Teacher Efficacy and Teacher Religiosity
The purpose of this study was to examine the relationship between teacher religiosity and teacher self-efficacy. The present study builds upon previous research which has shown purposeful work in everyday living fosters intrinsic motivation, religious orientation affects daily living, and teacher self-efficacy beliefs predict student achievement. Religiosity and self-efficacy data were gathered from public school teachers from a suburban school district in North Texas and from private Christian schools in Western Washington. The Age Universal I-E scale (a measure of religious orientation intended to capture how one lives out his/her religiosity), Teachers' Sense of Efficacy Scale, and a teacher characteristic form were used to collect data. In a multiple regression analysis, independent variables included teacher age, gender, grade level taught, experience level, campus type (public or private religious), and teacher religious orientation (intrinsic or extrinsic); the dependent variable was the score for teacher self-efficacy. The regression analysis resulted in an equation that explained only slightly more than 9% of the variance in the score for teacher self-efficacy. Three significant variables were identified--grade level taught, teacher age, and intrinsic religious orientation. Teacher age and teacher intrinsic religious orientation were the two most important contributors according to a comparison of beta weights. Intrinsic religious orientation contributed to the equation, but it acted as a suppressor variable in the study, having little predictive value by itself but contributing to the predictive value of the model. Based on the data collected, recommendations for future research and suggestions for field application are offered.
An Examination of the Relationship Between Teacher Efficacy and Teachers' Perceptions of Their Principals' Leadership Behaviors
Over the years there has been significant discussion of the connection between principal's leadership qualities and teacher efficacy. Students come to the classroom from stable, traditional, supportive home environments as well as from unstable, broken, and homeless situations. Teachers are asked to teach a classroom full of students with a wide range of learning abilities as well as a varied range of learning disabilities. The confidence to do this for the measure of a teacher's career takes a strong sense of efficacy. The purpose of this study was to examine the relationship between teachers' sense of efficacy and teachers' perceptions of their principals' leadership qualities that enhance and/or diminish the teachers' sense of efficacy. This study utilized both quantitative and qualitative research methods to study the effects of leadership qualities on teacher efficacy. Quantitative data was acquired utilizing the teacher sense of efficacy scale and the principal leadership questionnaire. Qualitative data was gathered through a focus group meeting of teachers with measurably strong efficacy to identify principal practices that affect teachers' efficacy. The study's outcomes reported that total respondent data indicates a generally positive relationship between these two variables. Subgroup analysis revealed varying results with diminishing relationships measured from elementary to secondary teachers. Qualitative information gathered from teachers with strong efficacy reported strategies that foster teacher efficacy, make teachers feel good about teaching and inhibit the development of teacher efficacy. The study recommends that principals and school administrators be especially knowledgeable of the six components of transformational leadership as well as the three aspects of teacher efficacy examined in this study. Being mindful of how daily leadership decisions not only fit within the transformational leadership constructs, but more importantly, how they affect good classroom teaching practices, should help principals plan and initiate strategies and programs that create a campus atmosphere more conducive to comprehensive learning.
An Examination of the Relationship Between Values, Family Environment, and Risk Behaviors Among College Students
The purpose of this study was to examine the roles that values and the family environment play in young adult engagement in risky behavior. One hundred seventy-two male and female college students between the ages of 18-25 completed a demographics questionnaire, the Aspirations Index which measures seven life-goal contents that represent different values, the Cognitive Appraisal of Risky Events that assesses young adults’ perceptions of the risks and benefits associated with involvement in risky activities as well as past involvement in risky behaviors and the Family Environment Scale to assess participants' perceptions of their current family environment. A series of regression analyses were then used to assess the relationship between three dimensions of the family environment and risky behavior involvement and the relationship between participants' intrinsic and extrinsic values and perceived positive consequences and negative consequences of risky behavior. Results from this study supported the idea that certain dimensions of the family environment are related to risk-taking behavior in emerging adults; however, contrary to previous research, the relationship dimension of the family environment was not predictive of young adult risk-taking. Moreover, family activities that communicate family values did not contribute any additional information to the prediction of risk-taking behavior. Findings from this study suggest that emerging adult values are related to emerging adult perceptions of the hazards and benefits of risky behavior. Results from this study also highlighted the importance of gender and first-generation college status in predicting risk-taking frequency as well as perceived benefits and hazards of risk-taking. Implications for findings of the current study, limitations, and recommendations for future research are also discussed.
An Examination of the Relationships Between Affective Traits and Existential Life Positions
Access: Use of this item is restricted to the UNT Community.
There were two major goals of this study - to examine validity of scores for the Boholst Life Position Scale and to examine potential associations between life positions and affective traits. Two hundred seventy-seven students enrolled in undergraduate psychology classes at a large university volunteered for the study. Concurrent validity of scores for the life position scale was supported based on two compared instruments. Pearson product-moment correlations for the comparisons were -.765 and .617, both statistically significant at the p < .001 level. Factor analysis demonstrated that the scale could accurately be conceptualized as consisting of two factors - an "I" factor and a "You" factor. MANOVA, ANOVA, multiple linear regression, and canonical correlation analysis were used to examine associations between life positions and the affective traits of angry, sad, glad, social anxiety, loneliness, and satisfaction with life. Subjects were catagorized into four groups representing their life position: "I'm OK, you're OK," "I'm OK, you're not OK," "I'm not OK, you're OK," and "I'm not OK, you're not OK." A MANOVA employing life position as the independent variable with four levels and the six affective traits as the dependent variables demonstrated statistical significance (p < .001 level) and h2 was .505. All six separate ANOVAs, with life position as the independent variable and each separate affective trait as the dependent variable, revealed statistical significance (p < .001) and h2 varied from a high of .396 for the sadness variable to a low of .116 for social anxiety. Six separate multiple linear regression equations using two independent variables, a measure of self-esteem and a measure of the perceived OK-ness of others, and each separate affective trait as the dependent variable, showed statistical significance (p < .001). The average Adjusted R2 was .475. Both canonical correlation functions were statistically significant (Rc12 = .77 and Rc22 = .21). In summary, life positions were strongly associated with specific affective traits.
An Examination of the Relationships between Personality Adjustment, Social Interaction Abilities, and Marital Adjustment
The problem with which this investigation was concerned, was that of determining the relationships between personality adjustment, social interaction abilities and marital adjustment. The following hypotheses were investigated: 1) there will be a significant relationship between individual personality adjustment and marital adjustment, and 2) there will be a significant relationship between marital harmony and social interaction abilities.
An examination of the riparian bottomland forest in north central Texas through ecology, history, field study, and computer simulation
Access: Use of this item is restricted to the UNT Community.
This paper explores the characterization of a riparian bottomland forest in north central Texas in two ways: field study, and computer simulation with the model ZELIG. First, context is provided in Chapter One with a brief description of a southern bottomland forest, the ecological services it provides, and a history of bottomland forests in Texas from the nineteenth century to the present. A report on a characterization study of the Lake Ray Roberts Greenbelt forest comprises Chapter Two. The final chapter reviews a phytosocial study of a remnant bottomland forest within the Greenbelt. Details of the ZELIG calibration process follow, with a discussion of ways to improve ZELIG's simulation of bottomland forests.
An Examination of the Role of Corporate Governance Structure in the Implementation of Enterprise Resource Planning (Erp) Systems: an International Perspective
Enterprise resource planning (ERP) systems are regarded as among the most innovative information technology products developed over the past two decades. Thus, they have become the backbone of management information systems in the organizations that have implemented them. The difficulties associated with their high failure rate, however, have been the subject of extensive studies. To expand on this knowledge, this study has two research objectives: to examine the relationship between corporate governance structures and implementation results and to investigate whether implementation outcomes vary by country. This study focuses on the project steering committee’s involvement, internal auditors’ participation, and the change management plan implementation. The results demonstrate that steering committee involvement is a primary factor that influenced the success of ERP implementation; and that institutional factors in country of deployment are important determinants of ERP project outcome.
An Examination of the Similarities and Differences Between Transformational and Authentic Leadership and Their Relationship to Followers' Outcomes
To date there is no comprehensive understanding of what leadership is, nor is there an agreement among different theorists on what a good or effective leader should be. The purpose of this dissertation is to examine the theoretical and empirical similarities and differences of two styles of leadership – transformational and authentic leadership. Follower outcomes, as well as, the effects of trust and psychological capital within these paradigms are of particular interest. Although theoretical differences are proposed for the leadership style, the extent of overlap suggests the need to more closely examine each theory. Pilot studies were created to validate original scenarios created for the study as well as to examine the validity and reliability of new measurement instruments. The dissertation is designed to determine whether the relationships between authentic leadership and a variety of follower outcomes including performance, affective commitment, satisfaction, trust, and organizational citizenship behavior are similar to those between transformational leadership and these outcomes. In addition, variables more unique to authentic leadership research including psychological capital and follower well-being were examined within both paradigms to determine whether their relationships are similar to each type of leadership style. An experimental study using Qualtrics was used to collect the data with the expectation that there would be significant differences in the two styles of leadership such that each explains unique variance in follower behavior. The results of this dissertation support the lack of perceptual difference between the two theories of leadership. The results of this experiment do not come completely unexpected because of the ethical overlap between the two styles of leadership. Although subjects in the experiment could differentiate authentic leadership from transformational leadership based on the manipulations, authentic leadership effects were not significantly different when compared to transformational leadership effects. As a result, analyses in my research do not support previous theoretical development of authentic leadership as a separate theory from transformational leadership. Consequently, lack of support for my hypotheses actually provides valuable information to the study of leadership and calls into question the continued pursuit of research on authentic leadership. Although this dissertation was constructed to investigate the differences between authentic leadership and transformational leadership relative to follower outcomes, results found for gender differences may highlight an additional component to these leadership paradigms not previously considered.
An Examination Of The Variation In Information Systems Project Cost Estimates: The Case Of Year 2000 Compliance Projects
The year 2000 (Y2K) problem presented a fortuitous opportunity to explore the relationship between estimated costs of software projects and five cost influence dimensions described by the Year 2000 Enterprise Cost Model (Kappelman, et al., 1998) -- organization, problem, solution, resources, and stage of completion. This research was a field study survey of (Y2K) project managers in industry, government, and education and part of a joint project that began in 1996 between the University of North Texas and the Y2K Working Group of the Society for Information Management (SIM). Evidence was found to support relationships between estimated costs and organization, problem, resources, and project stage but not for the solution dimension. Project stage appears to moderate the relationships for organization, particularly IS practices, and resources. A history of superior IS practices appears to mean lower estimated costs, especially for projects in larger IS organizations. Acquiring resources, especially external skills, appears to increase costs. Moreover, projects apparently have many individual differences, many related to size and to project stage, and their influences on costs appear to be at the sub-dimension or even the individual variable level. A Revised Year 2000 Enterprise Model is presented incorporating this granularity. Two primary conclusions can be drawn from this research: (1) large software projects are very complex and thus cost estimating is also; and (2) the devil of cost estimating is in the details of knowing which of the many possible variables are the important ones for each particular enterprise and project. This points to the importance of organizations keeping software project metrics and the historical calibration of cost-estimating practices. Project managers must understand the relevant details and their interaction and importance in order to successfully develop a cost estimate for a particular project, even when rational cost models are used. This research also indicates that software cost estimating has political as well as rational influences at play.
An Examination Of Three Texas High SchoolsÊ Restructuring Strategies That Resulted In An Academically Acceptable Rating
This study examined three high schools in a large urban school district in Texas that achieved an academically acceptable rating after being sanctioned to reconstitute by state agencies. Texas state accountability standards are a result of the No Child Left Behind Act of 2011 (NCLB). Texas state law requires schools to design a reconstitution plan after the second year of receiving an academically unacceptable school rating for failing to meet the required standards on state assessments, dropout rates, and graduation rates. The plan must be implemented by the third year. A mixed methods approach was used to uncover the strategies that were successful during the restructuring initiative. Data was obtained from three sources: interviews, document analysis and surveys. Interviews were conducted with district administrators, campus based administrators and teachers of the three high schools. A sample of core content teachers were surveyed using questions from the MetLife Survey of the American Teacher: Collaborating for Student Success. Results revealed that each school chose to engage in a major form of restructuring that included the formation of a themed based magnet school. A team approach was used to devise, implement, and monitor the reconstitution plan. Common strategies unveiled in the study included the use of common assessments, collaborative planning among core teachers, professional development, continuous monitoring of student absences, extended learning times for students, and a focus on college readiness. Survey data revealed that the majority of teachers believed that collaboration positively impacted student achievement. It is recommended that schools undergoing restructuring choose a reconstitution option that allows for flexibility, use multiple resources to foster school improvement, and develop restructuring plans that serve as living documents. Further research is needed to study the principal's role in achieving an academically acceptable rating. This study could also be expanded to compare restructuring strategies of high schools across the country that has been forced by federal mandates to reconstitute.
An Examination of Two Sextets of Carlos Chávez, Toccata for Percussion Instruments and Tambuco for Six Percussion Players
This lecture-recital deals with the two percussion sextets of Carlos Chavez. Each of the compositions is analyzed by examining compositional characteristics and performance problems. The selection, substitution, and construction of the necessary instruments for performance are explored. Suggestions for stage set-up are also included. The percussion ensemble has become an integral part of most high school and university percussion programs. Much of the literature composed for this medium has not become part of the standard literature. Chlvez's Toccata has obtained its place in the literature—it is one of the most often performed percussion works in the world. Although Tambuco has not yet attained the same status as Toccata, it is, nevertheless, an important contribution to the literature. An attempt is also made to identify the significance of these works by examining some of the early influences on Chavez's compositional style both from his native Mexico, and from other composers writing for percussion ensembles.
An Examination of Two Significant Percussion Compositions: Karlheinz Stockhausen's Zyklus and Ingolf Dahl's Duettino Concertante, a Lecture Recital Together with Five Recitals of Selected Works of A. Ginastera, A. Wilder, W. Kraft, and Others
Zvklus (1959) by Karlheinz Stockhausen and Duettino Concertante (1966) by Ingolf Dahl represent two of the most significant percussion compositions that present the percussionist as soloist. The performer of these works, either unaccompanied or accompanied by a non-percussion instrument, is featured as executant, interpreter, and improvisor. They are regarded as classics in the medium of multiple percussion because of their frequency of performance and their profound effect on notation, musical composition, and the technical expectations of the percussionist. This paper examines these compositions and their historical significance to both percussion literature and the percussionist. Each of these compositions is analzyed by examining instrumentation, compositional procedures, and performance problems. Finally, the notational procedures and role of the performer in these compositions are compared. A discussion of the development of the percussion batterie, percussion ensemble, and the important early solo multiple percussion compositions provides historical perspective for these compositions. This perspective is enhanced by consideration of biography, influences, and stylistic development of each composer.
Examination of Web-based teaching strategies at the University of North Texas.
This study examined the degree to which University of North Texas (UNT) instructors involved in Web-based instruction are implementing teaching strategies as identified in Chickering and Gamson's (1987) model, seven principles for good practice in undergraduate education. In addition, the study examined training received by instructors in developing and delivering a Web-based course and the relationships between their training and reported use of the teaching strategies in the seven principles. The study also examined the relationship between the number of Web-based courses taught and the use of the teaching strategies. Seventy-two surveys were distributed, with a return rate of 90.3%. Results of the first three research questions were as follows: (a) Self-taught (49%) and UNT Center for Distributed Learning (CDL) (31%) were the most frequently used types of training in preparation for teaching a Web-based course, whereas peer taught (17%) and conferences/workshops (3%) were the least used; (b) the average number of Web-based courses taught by the instructors was M = 8.26; and (c) the most frequently used principles were "Gives prompt feedback" and "Communicates high expectations." UNT CDL assists faculty with the development and delivery of online courses, offering a series of training courses to better prepare faculty to use Web-CT. The relationship between the training received and the instructors' reported use of the teaching strategies was examined using correlations and a MANOVA analysis. The correlations resulted in both positive and negative relationships between the four types of training and three of the principles. The MANOVA procedure found significant differences between self taught instructors and instructors that received most of their training through the CDL in relation to the principle "Respects diverse talents and ways of learning." The final research question examined the relationship between the number of courses taught and instructors' reported use of the teaching strategies, revealing that a positive correlation existed between the number of courses taught and four of the seven principles.
Examining an eating disorder model with African American women.
In the current study, I examined the general sociocultural model of eating disorders that suggests that sociocultural pressures leads to internalization, which in turn leads to body dissatisfaction and ultimately disordered eating. Because I am testing this model with a sample of African American women, I also am including acculturation as a variable of interest. Specifically, I hypothesized that (a) the experience of more societal pressure to be thin will be related to greater internalization, (b) higher levels of acculturation will be related to greater internalization, (c) internalization of the thin ideal will be directly and positively related to body image concern, and (d) body image concern will be associated with higher levels of disordered eating. It was determined that there is a direct, negative relationship between Level of Identification with Culture of Origin and Internalization. Perceived Pressure was directly and positively related to both Internalization and Body Image Concerns. Body Concerns and Internalization were both directly and positively related to Disordered Eating. These findings suggest that although many of the same constructs related to disordered eating in other ethnic groups are also related to disordered eating among African American women, the relationships between the factors differs across racial/ethnic groups. This information can help clinicians and researchers to better treat and understand the nature of disordered eating behavior and correlates among African American women.
Examining and Characterizing Changes in First Year High School Chemistry Curricula
Many students currently entering college are able to solve mathematical problems but often do not understand the chemistry concepts underlying their calculations. High school chemistry teachers from Texas and the United States (US) were surveyed as to what topics they teach in their chemistry classes. A subset of Texas teachers was also interviewed about their instruction. The survey indicated that less-experienced Texas teachers are omitting a number of topics from their chemistry instruction, as compared to more experienced teachers. No differences were seen for those topics among US teachers. Chemistry textbooks from 1930 to the current 2002 Texas state adoptions were analyzed for inclusion of these topics. The only textbooks that were missing topics were from the 1930s. All others contained the topics. In general, textbooks have been increasing numbers of questions and problems for each topic, with the number of quantitative problems increasing at a greater rate than qualitative problems. Analysis of interview transcripts revealed that the main reason for omission of topics by less-experienced Texas chemistry teachers is that these topics are not assessed on the Texas Assessment of Knowledge and Skills science exam. Omitted topics were both qualitative and quantitative; the common factor is that they are not tested. School administrators reportedly reinforce this practice. Archival data regarding textbook usage by general chemistry students showed that students' course grades are not correlated to the amount of time they spend using their textbook. With topics included in textbooks, and no relationship between textbook usage and student grades, observed changes in chemistry courses must be due to changes in classroom instruction. With new course standards adopted by Texas for chemistry and the development of end-of-course exams, these changes should produce graduates who understand chemistry concepts as well as they solve mathematical chemistry problems. Repeating this study in 5 years may show that increasing the amount of chemistry tested will produce students entering college with a better conceptual background in chemistry.
Examining Career Transitions during Mid-Adulthood through the Lens of Bioecological and Microdevelopmental Research
Access: Use of this item is restricted to the UNT Community.
Using hierarchical multiple linear regression, this study examined the predictive relationship between micro-career transitions and career related outcomes and how those relationships were moderated by equilibration style. Participants (n = 177) answered an online survey which included a variety of measures for control, predictor, moderator, and outcome criterion (i.e., demographic descriptors, Instrumentality, Openness, Job Insecurity, Social Support Satisfaction, Microtransitions, Equilibration Style, Job Satisfaction, Job Burnout, Life Dissatisfaction, and Career Optimism). Research questions addressed the nature of micro-career transitions (e.g., frequencies, average stress ratings, category types), their predictive relationship with job and career outcomes, and the moderating role of Identity Styles on that relationship. Micro-career transitions were described according to responses for the research sample (n = 638). Significant effects were discovered between microtransitions and career outcomes (p < .05 and .01). Equilibration styles were also established as having a moderating effect on the predictive relationship between microtransitions and career outcomes (p < .05 and .01). Interaction terms were decomposed to examine the direction of significant moderating effects. In all cases where interaction terms were significant, moderators enhanced the negative predictive relationship between microtransitions and career outcomes.
Examining Curvilinearity and Moderation in the Relationship between the Degree of Relatedness of Individual Diversification Actions and Firm Performance
Corporate diversification continues to be an important phenomenon in the modern business world. More than thirty years of research on diversification suggests that the degree of relatedness among a firm's business units is a factor that can affect firm performance, but the true effect of diversification relatedness on firm performance is still inconclusive. The purpose of this dissertation is to shed more light on this inconclusive association. However, attention is focused on the performance implications of individual diversification actions (e.g., acquisitions and joint ventures) rather than on the overall performance of firms with different levels of diversification. A non-experimental, longitudinal analysis of secondary data was conducted on over 450 unique acquisitions and on more than 210 joint ventures. Results suggest that even when individual diversification actions rather than entire business portfolios are examined, an inverted curvilinear association between diversification relatedness and performance is likely to emerge. This pattern is observed in both acquisitions and joint ventures. However, the association between diversification relatedness and performance in acquisitions is moderated by the level of industry adversity, though factors such as corporate coherence and heterogeneous experience do not moderate the association between diversification relatedness and performance. This study augments the body of knowledge on diversification and adds refinement to the traditional curvilinear finding regarding relatedness. By studying acquisitions and joint ventures independently, the results reveal differences in both slope and inflection points that suggest the relative impact of relatedness may vary depending on the mode of diversification.
Examining E-loyalty Model in Social Shopping Websites: the Impact of Social Shopping Website Quality on E-loyalty Formation
The purpose of this study is to examine the formation of customer e-loyalty to a social shopping website. The formation of customer e-loyalty to a social shopping website is examined based on cognitive-affective-conative-action loyalty framework. This study proposes that customer e-loyalty is strongly associated with website quality, e-satisfaction and participation. Seven website attributes (i.e., visual aesthetics, navigation, efficiency, user friendliness, security/privacy, entertainment and community driveness) identified in previous research are employed to measure website quality that affects e-loyalty formation. There are 449 data collected from a southwestern university in the U.S., but only the responses from 333 Pinterest users are used to test the hypotheses. Exploratory factor analysis is used to identify dimensionality of social shopping website attributes, and multiple regression and linear regression analysis are conducted to test hypotheses in this study. Results of the study indicate that five significant factors including efficiency, user friendliness, security/privacy, entertainment and community driveness are directly associated with customer e-loyalty. Indeed, such website quality factors as the determinant of cognitive e-loyalty directly affect overall customer satisfaction (affective e-loyalty), customer purchase/return intention to the website (conative e-loyalty), and customer participation, positive eWOM and co-shopping (action e-loyalty). The findings of this study have provided evidence that social shopping website quality dimensions are directly associated with customer e-loyalty to the website. Also, the findings have shown important implications to ensure quality website attributes to increase customer loyalty to a social shopping website.
Examining Employee Satisfaction, Customer Service and Customer Satisfaction in a Retail Banking Organization
Access: Use of this item is restricted to the UNT Community.
In the increasingly competitive world of retail banking, organizations are focusing their attention on customer service as a means of increasing customer loyalty and retention. With this goal of increasing customer retention, the link between the attitudes of the service provider (employee satisfaction), the customer interaction behaviors that those attitudes lead to (customer service quality), and the attitudes that those behaviors generate in the customer (customer satisfaction) has become an increasingly important area of investigation. The goal of this research is to analyze the relationships that exist between these three variables: employee satisfaction, customer service quality, and customer satisfaction in a mid-sized retail bank. Data from three separate surveys collected during the same time period in 137 branches of a regional bank are analyzed using multiple regression analysis to determine whether relationships and interactions exist at a banking center level. While results of the analyses did not show a significant relationship between the variables, issues relevant to this determination are discussed and conclusions drawn regarding the nature of these constructs.
Examining First-Graders' Construction of Knowledge of Graphophonemic and Orthographic Relationships: Reading and Writing Student-Selected Continuous Text
The purpose of this study was to examine first-graders' construction of knowledge of graphophonemic and orthographic relationships. Three levels of treatment were assigned randomly to three groups of first-graders in their first semester of first grade. Treatment varied in student engagement with reading and writing texts based on student interests and in the amount of interaction students had with one another and the researcher as they read, wrote, and examined words, word patterns, and graphophonemic relationships. The study was based on a quasi-experimental nonequivalent control group design (Campbell & Stanley, 1963) with an added within-subjects factor of 12 weekly test occasions. These weekly tests involved students writing a researcher-dictated continuous text selected by students in the full-treatment group from the larger portion of text read each week. Additional elements of qualitative research were included in the design and analyses. Quantitative analyses revealed statistically significant results. Qualitative data analyses confirmed that students who interacted daily with each other and the researcher in reading and writing activities constructed more knowledge about graphophonemic and orthographic relationships than peers from the partial-treatment group and the control group. Results led to conclusions and implications involving a reexamination of current and traditional methods of spelling instruction and assessment for young children.
Examining High School Coaches’ Likelihood to Refer To, Interest in Working With, and Plans to Hire a Sport Psychologist
The primary goal of the current study was to extend previous research suggesting that coaches are the primary gatekeepers who may be a barrier to working with athletes by examining high school coaches likelihood to refer to, interest in, and intention to hire a sport psychologist. Specifically, the current study examined relationships between high school coaches’ sex, age, and type of sport coached (i.e., contact vs. non-contact) and their likelihood to refer athletes to a sport psychologist for a variety of presenting issues (i.e., poor attentional focus, poor leadership, family issues, etc.). It also examined relationships between coaches’ sex, age, and type of sport coached (i.e., contact vs. non-contact) and their interest in working with a sport psychologist. Finally, the study examined reasons why coaches did not plan to hire a sport psychologist. An examination of the possible reasons that high school coaches do not plan to hire a sport psychologist served an exploratory purpose. Participants included 450 coaches who coached high school sports in the United States. Results indicated that female coaches and non-contact sport coaches were more likely to refer athletes to a sport psychologist for a variety of referral issues than male coaches and coaches of contact sports. Similarly, significantly more female coaches and non-contact sport coaches showed interest in working with a sport psychologist than male coaches and coaches of contact sports. Coaches who did not plan to hire a sport psychologist reported that cost, lack authority to hire, and lack of availability as primary reasons. Implications of the findings, limitations, and future directions are discussed.
Examining parenting outcomes of childhood sexual abuse survivors utilizing observation and self-report methods.
Childhood sexual abuse (CSA) is associated with negative outcomes in adulthood, including difficulty in relationships. Research has posited CSA may lead to insecure attachment in survivors, which may be the vehicle by which dysfunctional parent-child relationships develop. The purpose of the proposed study was to examine differences in parenting outcomes between CSA and non-CSA mothers utilizing both observational and self-report methods and to examine the unique impact of CSA on parenting attitudes. Abuse status was determined by scores on the Sexual Abuse subscale of the Childhood Trauma Questionnaire (CTQ), with the CSA group comprised of mothers scoring in the moderate to severe range. Mothers self-reported parenting attitudes on the Parent-Parental Acceptance Rejection Questionnaire/Control (P-PARQ/Control) and the Adult Adolescent Parenting Inventory-2 (AAPI-2), while parental depression was assessed with the revised Beck Depression Inventory (BDI-2). Parenting behaviors were observed by coding the Parent-Child Interaction Assessment (PCIA). Hypotheses were not supported until child gender was considered as a third variable. Results of MANCOVA analyses indicated CSA mothers, but not comparison mothers, exhibited significantly poorer limit-setting skills (h² = .21) with male children compared to female children, but did not self-report these differences. Although not statistically significant, small but potentially meaningful effect sizes were found when the self-reports of CSA mothers were compared to their observed behaviors. Specifically, CSA mothers displayed increased levels of physical nurturance (h² = .11) and role reversal (h² = .08) with male children compared to female children, but again, did not self-report these differences. Finally, CSA mothers, but not comparison mothers tended to self-report greater beliefs in corporal punishment with male children compared to females (h² = .08). Secondary findings revealed parental depression was the only unique predictor of parental nurturance, attitude toward corporal punishment, and role reversal. Findings confirm the importance of third variables, including child gender and parental depression. Theoretical and clinical implications are discussed, as well as limitations and future research directions.
Examining Self-efficacy in Community College Adjunct Faculty
Though professional development interventions are widespread in higher education, administrators often do not formally assess their effectiveness, particularly in relation to teacher self-efficacy. The purposes of this study were to determine if any statistically significant difference existed between the self-efficacy scores of adjunct faculty participants in a community college’s professional development program and nonparticipants and to identify the variables with a statistically significant relationship with self-efficacy. A modified version of the Teachers’ Sense of Efficacy Scale (TSES) was administered to 21 adjunct faculty participants in Lone Star College’s Adjunct Certification Program (ACP) and 312 adjunct faculty not currently participating in the program. A demographic questionnaire development by the researcher was also administered. Independent variables of the demographic questionnaire included gender, ethnicity, age, K-12 teaching experience, highest degree earned, subject taught, years of college teaching experience, and number of courses taught each semester. Paired t-test results indicated statistically significant differences in Efficacy in Instructional Strategies for adjunct participants in the ACP program. No significant differences were found for Efficacy in Student Engagement and Efficacy in Classroom Management. Multiple regression analyses indicated that gender has a statistically significant relationship to Efficacy Instructional Strategies. A statistically significant relationship was found for race for Efficacy in Classroom Management. Finally, analysis also indicated a positive relationship between race and gender for Efficacy in Student Engagement. No other statistically significant relationships were found across the other demographic variables. Findings of this study revealed that the ACP increased teacher self-efficacy across two of the three dimensions of the TSES indicating that the professional development intervention had a positive effect on the efficacy of its participants. The present study contributes to the research on teacher self-efficacy, adjunct faculty and professional development interventions.
Examining the Effect of Security Environment on U.S. Unilateral Military Intervention in Civil Conflicts
This study focuses on how perceived security environment affect U.S. unilateral, military intervention in civil conflicts, using the concept of Bayesian learning to illustrate how threat perceptions are formed, how they change, and how they affect the U.S. decision to intervene militarily in civil conflicts. I assess the validity of two primary hypotheses: (1) the U.S. is more likely to intervene in civil conflicts with connections to a threatening actor or ideology; and (2) the U.S. is more likely to intervene in civil conflicts for humanitarian motives in a less threatening security context. To test these hypotheses, I compare U.S. military intervention in three temporal contexts reflecting more threatening security contexts (Cold War and post-9/11) and less threatening security contexts (1992-2001). Results of logit regression analysis reveal that a conflict’s connection to a threatening actor or ideology is the most statistically and substantively significant determinant of U.S. military intervention in civil conflicts, both in more and less threatening security contexts. They also indicate that humanitarian motives are not a statistically significant determinant of U.S. military intervention in civil conflicts, even in a more benign security environment. These findings imply that U.S. unilateral military intervention is reserved for more direct national security threats, even those that are less grave, and that the perception of the U.S. as “global cop” may be misleading, at least in terms of unilateral military intervention.
Examining the Effects of Apparel Attributes on Perceived Copyright Infringement and the Relationship Between Perceived Risks and Purchase Intention of Knockoff Fashion
The growth of fast fashion retailers, availability of knockoff fashion apparel, and proposed apparel copyright law prompted this study. Fast fashion retailers are expanding rapidly and producing knockoffs fashion apparel in a matter of weeks, but current U.S. copyright laws do not protect apparel. The primary purpose of this study was to identify prominent visual fashion apparel attributes that could determine perceived copyright infringement. A secondary purpose was to examine the effects of fashion apparel attributes on perceived copyright infringement, perceived risk, and purchase intention. A sequential exploratory mixed method approach was used to explore the relationship between: Attributes, perceived copyright infringement, perceived risk, and purchase intention. This study consisted of a: Study one, study two, and study three. Twelve hypotheses were proposed, and five were supported. Quality significantly affected both perceived copyright infringement and purchase intention. Performance, social, and asset significantly affected purchase intention of knockoff fashion apparel.
Examining the Effects of Psychographics, Demographics, and Geographics on Time-Related Shopping Behaviors
The purpose of this study was to determine the effects of psychographic (shopping orientation, lifestyle, social class), demographic (gender, ethnicity, age), and geographic (area of residence) variables on time-related shopping behaviors when shopping for clothing for the self. The concept of time-related shopping behaviors has not been the focus of any study of the American market. Data (N = 550) were collected via a questionnaire with an online survey company. Through analysis of chi square statistics, ANOVA, Pearson product-moment correlation, and factor analysis, it was found that psychographics and demographics affected time-related and other shopping behaviors. Geographics was found to affect shopping behavior, but not specifically the time-related shopping behaviors studied.
Examining the effects of scheduled course time on mathematics achievement in high school students.
This study was designed to determine the effects of two different schedule types on mathematics achievement in public high school students. The instruments used included the Texas Assessment of Knowledge and Skills, given annually to all students in grades 3 through 11, the Texas Algebra I end-of-course examination, given as a district option to Algebra I students, and student final course grades as determined by classroom teachers. The study compared students' performance in these three areas during the 2004-2005 academic year in one suburban school district in North Texas. The study considers the type of schedule, either traditional or 8-block, between students in teachers' classes who teach the same course on both schedules concurrently. This study also investigates a qualitative aspect by including a short opinion survey of teachers' perceptions regarding student academic performance, teacher satisfaction and retention, and the ability to accomplish curricular goals. Findings from this research suggest course schedule does not have significant effects on student academic performance as measured using analyses of covariance comparisons with a 0.05 alpha-level, leading to the conclusion that a particular course schedule does not adversely impact student performance on academic measures. However, in some comparisons conducted within the course of the research, statistically significant results emerged. Qualitative data generated from a survey of teacher perceptions regarding the benefits of the two scheduling types, traditional 50-minute verses alternating day 8-block, suggested teachers preferred a traditional schedule over that of a block schedule design. Most teachers who responded to the survey instrument expressed the perception that traditional daily meeting classes allowed their students to be more successful. Additional research into the effects of scheduling types on students academic performance are suggested and would include examining larger population samples, a narrower study of specific courses within the field of mathematics, or an expansion of the content areas explored to fields such as science, languages, or non-academic core subjects, including the fine arts.
Examining the Engagement of Transfer Students in Texas Universities
The success of transfer students plays a critical role in improving the baccalaureate attainment rates of undergraduates attending 4-year higher education institutions in Texas; however, current indicators suggest transfer students have lower persistence and graduation rates relative to students who begin and complete their college education at one university (i.e., non-transfer students). Additionally, the research literature indicates a link between degree completion and engagement; however, transfer students are reported to be less engaged and less likely to persist than their counterparts. This quantitative study compared the engagement experiences of 2-year transfers, 4-year transfers, swirl transfer, and non-transfers by using National Survey of Student Engagement (NSSE) 2008 data to determine if there are any differences among these groups, and if these differences persist after controlling for individual and institutional covariates. the sample consisted of 2,000 seniors attending 4-year higher education institutions in Texas. the engagement scores of each group were compared using a multivariate analysis (MANOVA). This study found non-transfers were more engaged than each type of transfer student on Student-Faculty Interaction and Supportive Campus Environment factors; moreover, these differences generally persisted after controlling for residence, enrollment status, and institutional control (i.e., public vs. private).The data indicated no difference among the three transfer sub-groups for any of the engagement variables, which suggests their engagement experiences were similar. This research suggests that efforts to increase the participation and success rates of Texans, particularly those described as transfers, may be informed by how students perceive their engagement experiences; consequently, institutions may consider modifying and implementing policies that promote student participation in educationally purposeful activities leading to persistence and graduation.
Examining the Nature of Interactions which Facilitate Learning and Impact Reading Achievement During a Reading Apprenticeship: A Case Study of At-risk Adolescent Readers
The purpose of this qualitative case study was to explore the interactions that take place during a reading apprenticeship which facilitate the learning of reading strategies by adolescent students who are at the middle school level and are still at-risk for reading failure and to investigate how a reading apprenticeship affects reading achievement in the areas of fluency, vocabulary development, comprehension, and the self-perception of the reader. The case study was descriptive and interpretive in nature, and examined two students, each of whom was part of a one-to-one reading apprenticeship. The researcher served as participant observer in both cases and was the teacher in each of the one-to-one reading apprenticeships. The primary data set was qualitative in nature, and elements of quantitative data were also considered. Sessions included pretesting and posttesting using the Classroom Assessment of Reading Processes (Swearingen & Allen, 1997), reading from narrative or expository books, working with words, writing, and dialoguing about the reading. Reading strategies were directly taught, modeled, and reinforced by the teacher/researcher with the goal of the students internalizing the strategies and improving their reading in the areas of fluency, vocabulary development, and comprehension, as well as improving their attitudes toward reading and their self-perception about their reading ability. This study described a reading apprenticeship which positively impacted reading achievement for two students in the areas of fluency, comprehension, and vocabulary development, as well as influencing their motivation for reading and their self-perceptions as readers. The environment of the reading apprenticeship, the dialogue that occurred throughout the reading apprenticeship, and strategy instruction, modeling, and reinforcement were found to be factors and interactions which facilitated learning during this intervention.
Examining the Origins of Sociology: Continuities and Divergences Between Ibn Khaldun, Giambattista Vico, August Comte, Ludwig Gumplowicz, and Emile Durkheim
This thesis examines the extent to which Ibn Khaldun can legitimately be considered a founding father of sociology. To pursue this research, Khaldun's theoretical framework will be compared with four Western scholars: Auguste Comte, Emile Durkheim, Giambattista Vico, and Ludwig Gumplowicz. This paper begins with an Introduction (Chapter I), followed by a general overview of Khaldun's work (Chapter II). Next, Khaldun's work is compared to that of Auguste Comte (Chapter III), Emile Durkheim (Chapter IV), Ludwig Gumplowicz (Chapter V) and Giambattista Vico (Chapter VI). In each of these chapters, Khaldun is compared and contrasted to the other social theorist, illustrating their similarities and considering their differences. Finally, in Chapter VII, I put forth conclusions that consider the extent to which Khaldun can validly be considered a founding father of sociology.
Examining the relationship between employee-superior conflict and voluntary turnover in the workplace: A comparison of companies across industries.
Employee turnover is a topic of concern for a multitude of organizations. A variety of work-related factors play into why an individual chooses to change jobs, but these are often symptoms of underlying issues, such as conflict. This study set out to determine if conflict between employees and their superiors has an impact on the level of turnover in an organization, and if manufacturing versus non-manufacturing industry type makes a difference. The generated data were based on 141 selected cases from the ethnographic cases in the Workplace Ethnography Project. Linear and logistic regressions were performed, finding that there is a significant relationship between conflict with superiors and the level of turnover.
Examining the Relationship Between Individual and Work Environment Characteristics and Learning Transfer Factors
To impact student learning, educators’ implementation, or transfer, of new knowledge, skills, dispositions, and practices to daily work is the primary purpose of professional learning. The purpose of this study was to assess the multivariate relationship between individual and work environment characteristics as measured by the Collective Efficacy Scale and Dimensions of Learning Organization Questionnaire, respectively, and learning transfer factors as measured by the Learning Transfer System Inventory. The sample consisted of 249 PK-12 grade school- based instructional staff members of an education association. Canonical correlation and commonality analyses required using the two individual and work environment characteristics of learning culture and collective efficacy as predictor variables of the five learning transfer factors of performance self-efficacy, transfer-effort performance expectations, performance outcome expectations, performance coaching, and resistance to change to evaluate the multivariate between the two variable sets. Learning culture and collective efficacy demonstrated a relationship to resistance to change and performance outcome expectations. Learning culture and collective efficacy were insufficient to transfer-effort performance expectations, attend to performance self-efficacy beliefs, and increase support for transfer (i.e., performance coaching) factors. These findings might guide the decisions and practice of individuals with responsibility to plan, implement, and evaluate professional learning, and provide the conditions necessary for changing educational practice while increasing support for and building educators’ confidence about implementation. Further research may confirm the findings and enhance generalizability.
Examining the Relationship Between Persistence in Attendance in an Afterschool Program and an Early Warning Index for Dropout
School districts constantly struggle to find solutions to address the high school dropout problem. Literature supports the need to identify and intervene with these students earlier and in more systemic ways. The purpose of this study was to conduct a longitudinal examination of the relationship between sustained afterschool participation and the host district’s early warning index (EWI) associated with school dropout. Data included 65,341 students participating in an urban school district’s after school program from school years 2000-2001 through 2011-2012. The district serves more than 80,000 students annually. Data represented students in Pre-Kindergarten through Grade 12, and length of participation ranged from 1 through 12 years. Results indicated that student risk increased over time and that persistent participation in afterschool programming had a significant relationship with student individual growth trajectories. Slower growth rates, as evidenced through successive models, supported students being positively impacted by program participation. Additionally, participation was more meaningful if students persisted, as noted in the lower EWI rates, as compared to students who attended less consistently.
Examining the Relationship between Variability in Acquisition and Variability in Extinction
Using the "revealed operant" technique, variability during acquisition and extinction was examined with measures of response rate and a detailed analysis of response topography. During acquisition, subjects learned to emit four response patterns. A continuous schedule of reinforcement (CRF) for 100 repetitions was used for each pattern and a 30 min extinction phase immediately followed. One group of subjects learned the response patterns via a "trial-and-error" method. This resulted in a wide range of variability during acquisition and extinction. Only one subject emitted a substantial amount of resurgent behavior. A second group of subjects was given instructions on what keys to press to earn reinforcers. This group had less variability in acquisition and extinction and resurgent responding was prevalent.
Examining the Role of Latitude and Differential Insolation in Asymmetrical Valley Development
Valley development through erosional processes typically tends to create symmetrical valleys. Over time, water cuts through the substrate to create valleys, gorges, and canyons for which the sides are the valley are evenly sloped. However, there are anomalies to this process. Asymmetrical valleys have been well-documented even in areas of uniform substrate or little tectonic uplift. One proposed explanation for the asymmetry of these valleys is differential insolation. This may lead to different microclimates from one slope to another which alter the rate and extent of erosion. Since the differences in received insolation vary with latitude (especially in streams that flow along an east/west axis), it follows that the degree of asymmetry should also vary with latitude if differential insolation is a primary driving factor in the development of these valleys. To evaluate if insolation plays a role in the development of asymmetrical valleys, this study examines variability in asymmetry across 447 valleys in nine study areas located at different latitudes. The degree of asymmetry for each valley was measured by using 30 meter resolution digital elevation models (DEMs) to determine the slope angle of each side of the valley. Asymmetry was measured by computing a ratio of the average slope angle for each side of the valley (larger value divided by smaller). If the resulting value is one, the valley is deemed symmetrical. As the value increases, the degree of asymmetry increases. This investigation found that contrary to expectations, valleys at lower latitudes tend to have a higher degree of asymmetry than those at higher latitudes, which suggests that differential insolation does not play a major role in the development of these valleys. Instead, this study found that high altitudes and low latitudes are more frequently associated with a higher degree of asymmetry. These unexpected findings open the door to new avenues of investigation into the causes of asymmetrical valley development.
Examining the Shade/flood Tolerance Tradeoff Hypothesis in Bottomland Herbs Through Field Study and Experimentation
While there is growing evidence that shade/flood tolerance tradeoffs may be important in distributions of bottomland hardwood trees and indications that they should apply to herbs, no studies have definitively explored this possibility. Four years of field data following historic flooding were supplemented with a greenhouse experiment designed to identify interactions congruent with tradeoffs. Fifteen bottomland species were grown in two levels of water availability and three levels of shade over 10 weeks. Results indicate responses of Fimbristylis vahlii and Ammannia robusta are consistent with tradeoffs. Modification of classical allometric responses to shade by substrate saturation indicates a potential mechanism for the tradeoff in A. robusta. Responses indicating potential for increased susceptibility to physical flooding disturbance are also discussed.
Examining Visual Art Experiences for Relationship Building in Shared-site Locations
This study explored the perceptions of 74 activity directors responsible for the intergenerational programming that is currently taking place at shared-sites, facilities where older adults and young people receive services and programs simultaneously in a co-located space. Data for this study was collected through a national survey of 149 shared-sites collected from the Generations United data base. the questionnaire asked respondents about their facility’s intergenerational programming, demographic information, and perceived sense of community exhibited by participants in the intergenerational program. Descriptive data regarding the location, primary emphasis, ages and number served, and specific program characteristics, including visual art programming, at IGSS facilities were collected and analyzed. Results from the analysis were reported with limitations. There was a statistical significance suggested in the association of the frequency and duration of art activities with some of the sense of community variables. the study is valuable in determining the current demographics of IGSS facilities that offer visual art programs. Further research needs to be conducted to answer questions regarding the specific role that the visual arts play in creating a sense of community among intergenerational participants at shared-site facilities.
