The Limits of Arbitrage and Stock Mispricing: Evidence from Decomposing the Market to Book Ratio (open access)

The Limits of Arbitrage and Stock Mispricing: Evidence from Decomposing the Market to Book Ratio

The purpose of this paper is to investigate the effect of the "limits of arbitrage" on securities mispricing. Specifically, I investigate the effect of the availability of substitutes and financial constraints on stock mispricing. In addition, this study investigates the difference in the limits of arbitrage, in the sense that it will lead to lower mispricing for these stocks, relative to non-S&P 500 stocks. I also examine if the lower mispricing can be attributed to their lower limits of arbitrage. Modern finance theory and efficient market hypothesis suggest that security prices, at equilibrium, should reflect their fundamental value. If the market price deviates from the intrinsic value, then a risk-free profit opportunity has emerged and arbitrageurs will eliminate mispricing and equilibrium is restored. This arbitrage process is characterized by large number of arbitrageurs which have infinite access to capital. However, a better description of reality is that there are few numbers of arbitrageurs to the extent that they are highly specialized; and they have limited access to capital. Under these condition arbitrage is no more a risk-free activity and can be limited by several factors such as arbitrage risk and transaction costs. Other factors that are discussed in the literature …

Photo-induced Toxicity of Deepwater Horizon Spill Oil to Four Native Gulf of Mexico Species (open access)

Photo-induced Toxicity of Deepwater Horizon Spill Oil to Four Native Gulf of Mexico Species

The 2010 Deepwater Horizon oil spill resulted in the accidental release of millions of barrels of crude oil into the Gulf of Mexico (GoM). Photo-induced toxicity following co-exposure to ultraviolet (UV) radiation is one mechanism by which polycyclic aromatic hydrocarbons (PAHs) from oil spills may exert toxicity. Blue crab (Callinectes sapidus) are an important commercial and ecological resource in the Gulf of Mexico and their largely transparent larvae may make them sensitive to PAH photo-induced toxicity. Mahi-mahi (Coryphaena hippurus), an important fishery resource, have positively buoyant, transparent eggs. These characteristics may result in mahi-mahi embryos being at particular risk from photo-induced toxicity. Red drum (Sciaenops ocellatus) and speckled seatrout (Cynoscion nebulosus) are both important fishery resources in the GoM. They spawn near-shore and produce positively buoyant embryos that hatch into larvae in about 24 h. The goal of this body of work was to determine whether exposure to UV as natural sunlight enhances the toxicity of crude oil to early lifestage GoM species. Larval and embryonic organisms were exposed to several dilutions of water accommodated fractions (WAF) from several different oils collected in the field under chain of custody during the 2010 spill and two to three gradations of natural …

Health-related Quality of Life and Social Engagement in Assisted Living Facilities (open access)

Health-related Quality of Life and Social Engagement in Assisted Living Facilities

This research project aims to clarify the factors that impact successful aging in Assisted Living facilities (ALFs) in Denton County, Texas. We hypothesize that social disengagement decreases physical and mental components of quality of life. This exploratory research project employed standardized questionnaires to assess residents in the following domains; HRQOL, social engagement status, level of cognition, depression, and the level of functioning. This study collected data from 75 participants living in five ALFs. The average of Physical Component Scale (PCS) and Mental Component Scale (MCS) was 35.33, and 53.62 respectively. None of the participants had five or more social contacts out of facilities, and two-third of them had two or less social contacts. On average, those participants who were more socially engaged had higher score of MCS compared with disengaged counterparts. The level of physical function significantly affects social engagement, when people with more disabilities are more likely to be socially disengaged. Social engagement and depression significantly impact MCS, when depression is a mediating factor between social engagement and mental component of quality of life. Considering the expansion in aging population in the United States within the next three decades, the demand for high quality long-term care will skyrocket consequently. …

A Comparative Analysis of State Funds on Student Achievement of Economically Disadvantaged Elementary Schools in Independent School Districts and Charter Schools in the State of Texas (open access)

A Comparative Analysis of State Funds on Student Achievement of Economically Disadvantaged Elementary Schools in Independent School Districts and Charter Schools in the State of Texas

The purpose of this study was to evaluate the relationship between the instructional outcomes in the independent school districts and charter schools in relation to the expenditure of public funds for instruction and total operating expenditures from the general fund. The study considered Texas elementary charter schools and independent school districts, whose school populations were identified as having greater than or equal to 50% of economically disadvantaged students, according to the Texas Academic Excellence Indicator System (AEIS). The study made use of multiple regression and was an ex post facto cross-sectional analysis utilizing production function theory. The study’s outcomes reported the difference in student achievement between elementary schools in independent public school districts and charter schools were small to negligible for math and reading achievement. The study also reported, there is no statistically significant difference in per pupil expenditure of public funds between elementary schools in independent public school districts and charter schools. Furthermore, there is no statistically significant relationship between student achievement and per pupil expenditure of public funds on elementary schools in independent public school districts and charter schools.

Exploring the Dual-natured Impact of Digital Technology on Student-classroom Engagement in a Texas Public High School (open access)

Exploring the Dual-natured Impact of Digital Technology on Student-classroom Engagement in a Texas Public High School

The past decade has become rife with an eagerness to integrate new digital technology into teaching. While there have been decades of research done on the importance of curriculum and pedagogy on student engagement, findings of actual technology integration are scarce. Moreover, what does it take to engage students in classroom activities and lessons when technology is introduced? The purpose of this study was to explore how digital technology, when integrated into classroom teaching and activities, impacted the students-classroom engagement based on the interim-cognitive, meta-cognitive, motivational, and behavioral markers. This was explored in a Texas public high school across the four core classes (English, Math, Science, and Social Studies. Data was collected in the form of observational field notes, transcripts of recorded lessons, and Likert-scaled surveys. Thematic analysis was used in analyzing qualitative data, Pearson’s correlation of those components found by factor analysis verified three of the five themes identified from the thematic analysis with statistical significance. The findings suggest that mere use of technology does not have a profound impact on student engagement. Instead, technology tends to amplify the existing classroom culture and social norms agreed upon between the teacher and their students. Texas teachers and students are also …

A Tale of Two Cities: Exploring the Dual Language Program Implementation and Biliteracy Trajectories at Two Schools (open access)

A Tale of Two Cities: Exploring the Dual Language Program Implementation and Biliteracy Trajectories at Two Schools

With the increase in emergent bilinguals and higher standards for all, the challenge for educational stakeholders is to fully utilize dual language programs as a prominent means toward meeting and surpassing rigorous state and national standards. Part of maximizing dual language programs’ impact, and the purpose of this study, was to provide detailed analyses of program models and student biliteracy development. Thus, the research questions sought to explore the level of understanding and implementation of dual language programs in general and the biliteracy component in particular at each campus, before documenting the second through fifth grade English and Spanish reading biliteracy trajectories of students at each school. Both campuses experienced more challenges in the implementation of the program structure, staff quality, and professional development rather than in curriculum and instruction. Furthermore, although both campuses’ students experienced positive trajectories towards biliteracy by the end of fifth grade, each campus was characterized by different rates and correlation between English and Spanish reading growth in each grade. Finally, the researcher conducted a split plot MANOVA to examine how much variance in the biliteracy trajectories was explained by school attendance, gender, initial English oral language and initial Spanish oral language; only school of attendance …

Levanten La Mano Si Me Entienden: Receptive Bilinguals’ Linguistic and Cultural Perceptions in Secondary Spanish Classes (open access)

Levanten La Mano Si Me Entienden: Receptive Bilinguals’ Linguistic and Cultural Perceptions in Secondary Spanish Classes

Receptive bilinguals have been in a dilemma of knowing just enough Spanish to write and aurally comprehend the curriculum at the beginning-intermediate levels of a Spanish language course. This dichotomy in classrooms with mixed-ability learners has created a need to reconsider placement and pedagogical structures tailored for these students in foreign language courses. Thus, this descriptive study examined the perceptions of receptive bilinguals, drawn from two secondary Spanish courses regarding receptive bilinguals’ language use, personal Spanish language abilities and confidence, personal beliefs about the language, and contentment with the course. For this study, 31 participants were selected from two public high schools in a suburb of a large metropolitan area in north Texas. Two surveys, a listening assessment and an online questionnaire, were administered at the end of the academic year. The Likert questionnaire items were analyzed using SPSS software, while open-ended questions were coded for recurrent themes. Analyses revealed four major findings. First, with regard to influence on language use, participants’ grandparents created the most interaction with the Spanish language when compared with the other family groups. In addition, Spanish influence through television, literature, radio, and music contributed to students’ early childhood Spanish learning. Second, as to language preference, …

Does an Online Post-baccalaureate Secondary Teacher Certification Program Produce Certified Teachers Who Remain in the Field? (open access)

Does an Online Post-baccalaureate Secondary Teacher Certification Program Produce Certified Teachers Who Remain in the Field?

Given issues in education concerning teacher shortages, the omnipresence of alternative certification programs and the growth of online programs in higher education, this study investigated teacher retention for 77 secondary education teachers who completed an online teacher preparation program in Texas. Teacher retention was examined from 2003-2013 and investigated the influence of factors such personal characteristics, working conditions and school setting characteristics on teacher retention. Data was collected electronically utilizing a survey instrument designed by two teacher education experts and I. A total of 21 variables and two open-ended questions were investigated using the survey instrument. Exploratory factor and hierarchical multiple regression analyses were conducted to identify a multi-factor model for teacher retention utilizing the participants' survey responses. These analyses yielded evidence of the program's effectiveness in preparing teachers for long careers. Specifically, the areas of program support, field experience, and classroom management were statistically significant factors that contributed positively to teacher retention. Additionally, variables outside the program, were examined. These factors included personal characteristics, working conditions, and school setting factors. The predictor model accounted for 56% of the variance; F (17, 54) = 3.015; p = < 0.001. In particular, working conditions contributed to 41% of the variance associated …

The Relationship of Peer Leadership Employment to Academic Outcomes in Texas Institutions of Higher Education (open access)

The Relationship of Peer Leadership Employment to Academic Outcomes in Texas Institutions of Higher Education

The purpose of this quantitative study was to examine the relationship of participation and involvement in an undergraduate student success program to academic success and persistence among students in three programs sponsored by the Texas Higher Education Coordinating Board (THECB): the G-Force Collegiate Work-Study Mentorship Program, the Advancement Via Individual Determination (AVID) for Higher Education (AHE) program, and the THECB work-study program. The sample was identified using data from the THECB during the 2009-2013 academic years. Compared to THECB work-study students, significantly more AHE and G-Force students persisted toward graduation while engaged in the program (p < .001). ANOVA indicated that AHE students had a higher average GPA compared to G-Force and THECB work-study students, controlled for gender, race/ethnicity, pre-program GPA, and length of time in the position. Regression analyses found no statistically significant relationship between program associations and persistence towards graduation or GPA. Results suggest that although participation in a peer leadership programs such as AHE and G-Force encourage greater academic achievement and persistence, there is no direct relation to the achievement of these outcome variables. Implications of the study suggest the need for a deeper analysis into elements of peer leadership programs that contribute to student success, an …
