Retinoic acid Treatment Affects Kidney Development and Osmoregulatory System in the Developing Chicken (Gallus Gallus)
Development is a dynamic process characterized by critical periods in which organ systems are sensitive to changes in the surrounding environment. In the current study, critical windows of embryonic growth and kidney development were assessed in the embryonic chicken. All‐trans retinoic acid (tRA) influences not only organogenesis and cell proliferation, but also targets metanephric kidney nephrogenesis. Embryonic chickens were given a single injection of tRA on embryonic day 8. tRA decreased embryo, kidney, and heart mass from day 16 to day 18. However, mass specific kidney and heart masses showed no differences. Whole blood, plasma, and allantoic fluid osmolality were altered in tRA treated embryos from day 16 to day 18. In addition, hematocrit, red blood cell count, and hemoglobin concentration were altered in tRA treated embryos. The results suggest that although nephrogenesis was not affected by tRA, the developing osmoregulatory system was altered in tRA treated embryos.

Economic Motivation of the Ex-Dividend Day Anomaly: Evidence from an Alternative Tax Environment
Several studies have observed that stocks tend to drop by an amount that is less than the dividend on the ex-dividend day, the so-called ex-dividend day anomaly. However, there still remains a lack of consensus for a single explanation of this anomaly. Different from other studies, this dissertation attempts to answer the primary research question: How can investors make trading profits from the ex-dividend day anomaly and how much can they earn? With this goal, I examine the economic motivations of equity investors through four main hypotheses identified in the anomaly’s literature: the tax differential hypothesis, the short-term trading hypothesis, the tick size hypothesis, and the leverage hypothesis. While the U.S. ex-dividend anomaly is well studied, I examine a long data window (1975 to 2010) of Thailand data. The unique structure of the Thai stock market allows me to assess all four main hypotheses proposed in the literature simultaneously. Although I extract the sample data from two data sources, I demonstrate that the combined data are consistently sampled. I further construct three trading strategies: “daily return,” “lag one daily return,” and “weekly return” to alleviate the potential effect of irregular data observation. I find that the ex-dividend day anomaly exists …

Comparing Latent Dirichlet Allocation and Latent Semantic Analysis as Classifiers
In the Information Age, a proliferation of unstructured text electronic documents exists. Processing these documents by humans is a daunting task as humans have limited cognitive abilities for processing large volumes of documents that can often be extremely lengthy. To address this problem, text data computer algorithms are being developed. Latent Semantic Analysis (LSA) and Latent Dirichlet Allocation (LDA) are two text data computer algorithms that have received much attention individually in the text data literature for topic extraction studies but not for document classification nor for comparison studies. Since classification is considered an important human function and has been studied in the areas of cognitive science and information science, in this dissertation a research study was performed to compare LDA, LSA and humans as document classifiers. The research questions posed in this study are: R1: How accurate is LDA and LSA in classifying documents in a corpus of textual data over a known set of topics? R2: How accurate are humans in performing the same classification task? R3: How does LDA classification performance compare to LSA classification performance? To address these questions, a classification study involving human subjects was designed where humans were asked to generate and classify documents …

Senior Graduating Nursing Students: Career Choices in Gerontological Nursing in Response to Expanding Geriatric Population
Access to healthcare is needed and wanted by people of all ages and especially by those of the older population. The number of people in the 65 years of age and older population is rapidly growing with their needs expected to have a significant impact on the existing healthcare system and healthcare providers. The impact will be critical given the severe shortage of healthcare providers, especially of nurses and the rate of services being more often provided in non-hospital settings. The objectives of the study were to discover the plans of graduating nursing students as they choose their first place of employment, if they have future plans to pursue a nursing advance practice degree, and if they are very happy with their decision to become a nurse. Data for the study were obtained from a questionnaire presented to senior graduating nursing students. The findings were: (a) Most students prefer a hospital setting. (b) Younger students are three times as likely to seek out the hospital, and 1/3 of the students seek out the hospital setting because they were encouraged to become a nurse. (c) About 70% of the students want to work with their friends while 1/3 will seek the …

Predictive Relationships among Learner Characteristics, Academic Involvement, and Doctoral Education Outcomes
The literature identifies multiple factors pertinent to learner characteristics and learning experiences that may promote doctoral education outcomes, and yet little quantitative research has examined relationships between those factors deemed important in the effectiveness of doctoral education. This study sought to examine predictive relationships among doctoral students’ learner characteristics, their involvement in mentorship and intellectual community, and doctoral education outcomes. Using Astin’s theory of involvement and the literature on signature pedagogies in doctoral education as conceptual guides, a survey instrument was constructed for the purpose of measuring variables identified as relevant to the effective formation of scholars. Central to the conceptualization of this study was academic involvement as represented by mentorship and intellectual community. The instrument was validated in a two-stage pilot testing process and administered to doctoral candidates at three public Texas higher education institutions. Of the 217 participants, the majority were female, White (Non-Hispanic), US citizens, and were pursuing education doctorates. Data were analyzed using multivariate statistical analyses. Reliability and validity estimates indicated psychometric integrity of the 20 observed variables measured to represent the constructs of mentorship and intellectual community. Results indicated that doctoral students’ learner characteristics were not notably predictive of doctoral students’ degree of involvement in …

Factors Related to the Selection of Information Sources: A Study of Ramkhamhaeng University Regional Campuses Graduate Students
This study assessed students’ satisfaction with Ramkhamhaeng University regional library services (RURLs) and the perceived quality of information retrieved from other information sources. In particular, this study investigated factors relating to regional students’ selection of information sources to meet their information needs. The researcher applied the principle of least effort and Simon’s satisficing theory for this study. The former principle governs and predicts the selection of these students’ perceived source accessibility, whereas the latter theory explains the selection and use of the information retrieved without considering whether the information is optimal. This study employed a web-based survey to collect data from 188 respondents. The researcher found that convenience and ease of use were the top two variables relating to respondent’s selection of information sources and use. The Internet had the highest mean for convenience. Results of testing a multiple linear regression model of all four RURCs showed that these four independent variables (convenience, ease of use, availability, and familiarity) were able to explain 69% of the total variance in the frequency of use of information sources. Convenience and ease of use were able to increase respondents’ perceived source accessibility and explain the variance of the frequency of use of sources …

Teacher Decision-Making: Cultural Mediation in Two High School English Language Arts Classrooms
Although studies have addressed high school English language arts (ELA) instruction, little is known about the decision-making process of ELA teachers. How do teachers decide between the resources and instructional strategies at their disposal? This study focused on two monolingual teachers who were in different schools and grades. They were teaching mainstream students or English Language Learners. Both employed an approach to writing instruction that emphasized cultural mediation. Two questions guided this study: How does the enactment of culturally mediated writing instruction (CMWI) in a mainstream classroom compare to the enactment in an ESL classroom? What is the nature of teacher decision-making in these high school classrooms during English language arts instruction? Data were collected and analyzed using qualitative methodologies. The findings suggest that one teacher, who was familiar with CMWI’s principles and practices and saw students as partners, focused her decisions on engagement and participation. The other teacher deliberately embedded CMWI as an instructional stance. Her decisions focused on empathy, caring and meaningful connections. These teachers enacted CMWI in different ways to meet their students’ needs. They embraced the students’ cultural resources, used and built on their linguistic knowledge, expanded thinking strategies to make difficult information comprehensible, provided authentic …

Mosques in France: The Visible Presence of Islam
Numerous laws are being directed toward subduing the visible presence of Islam throughout France, and in return French Muslims are becoming bolder in the projection of their faith. This thesis examines the presence of Islam in France throughout history and in contemporary French civilization. Specifically, this thesis addresses the issues regarding the visible presence of Islam in France through such institutions as mosques and how they are the key symbols representing the prominence of Islam in France. It looks at what lies in the collective French mind that creates such an influence on today's policies and outlook, as well as identifies the key characters that dominate the current affairs surrounding Islam in France. The thesis reviews the country's past relations with the visible presence of Islam through the controversies surrounding the construction of famous mosques. In addition, this thesis underlines key areas where both the State and the Muslim population must make concessions in order to avoid further conflict.
