Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most abundant environmental pharmaceutical contaminants. In this study, a proteomic analysis was conducted to identify proteins differentially expressed in gill tissue of zebrafish (Danio rerio) after a 14-day exposure to the NSAIDs ibuprofen or naproxen. A total of 104 proteins with altered expression as indicated by 2-dimensional electrophoresis were analyzed by liquid chromatography with ion trap mass spectrometry (MS/MS). A total of 14 proteins fulfilled our requirements for identification which included consistency among replicate gels as well as successful MS/MS ion searches with the MASCOT database. The most prominent feature of the differential protein expression observed after NSAID exposure was an up-regulation of proteins belonging to the globin family which are involved in the transport of oxygen from gills and availability of heme molecules required for synthesis of cyclooxygenase. Differential expression was observed at exposure concentrations as low as 1-10 µg/L indicating that altered gene expression may occur in fish subjected to environmentally realistic levels of NSAID exposure.

Consider a family of cubic parabolic polynomials given by for non-zero complex parameters such that for each the polynomial is a parabolic polynomial, that is, the polynomial has a parabolic fixed point and the Julia set of , denoted by , does not contain any critical points of . We also assumed that for each , one finite critical point of the polynomial escapes to the super-attracting fixed point infinity. So, the Julia sets are disconnected. The concern about the family is that the members of this family are generally not even bi-Lipschitz conjugate on their Julia sets. We have proved that the parameter set is open and contains a deleted neighborhood of the origin 0. Our main result is that the Hausdorff dimension function defined by is real analytic. To prove this we have constructed a holomorphic family of holomorphic parabolic graph directed Markov systems whose limit sets coincide with the Julia sets of polynomials up to a countable set, and hence have the same Hausdorff dimension. Then we associate to this holomorphic family of holomorphic parabolic graph directed Markov systems an analytic family, call it , of conformal graph directed Markov systems with infinite number of edges in …

In 2011, the National Association of Schools of Music (NASM) took an official position to recognize the importance of hearing health and injury prevention as a standard for all member-accredited institutions. This is the largest national acknowledgement promoting hearing health and safety within the music discipline and among students seeking a music degree in the United States. The purpose of the study is to describe what conductors (i.e., instructors) of college-based ensembles know about hearing health and the generation of sound intensity levels. The study aimed to describe the 1) current state of conductors’ awareness and knowledge of sound intensity levels, 2) current attitudes of conductors toward learning and sharing knowledge of sound intensity levels, and 3) current teaching practices of conductors in regard to equipment usage (e.g. sound level meter, noise dosimeter, hearing protection devices) relating to sound measurement and exposure. Findings indicate 80.2% of conductors (N = 162, 66% employed by NASM-accredited institutions) agree that sounds generated during ensemble-based instructional activities (EBIAs) in college-level schools of music are capable of harming human hearing, but 24.1% “do not know” if EBIAs they conduct ever exceed sound intensity levels capable of harming human hearing, 54.9% do not know “what services …

Social agents in the youth sport domain (coaches, parents, and peers) play a crucial role in developing the motivational approaches of youth sport athletes. One theory which has been useful in explaining the important role of such social agents has been Achievement Goal Theory (Nicholls, 1989). Specifically, Achievement Goal Theory was used to delineate various peer behaviors as being task-involving (Ntoumanis & Vazou, 2005) and was used to predict subsequent relationships relationship between the task-involving motivational-climate created by teammates and athletes’ mastery goal orientations and self-esteem, sport competence, enjoyment, and intention to continue playing sport. Participants were 405 boys aged 12-15 years. Using structural equation modeling, an exploratory analysis and confirmatory analysis revealed that higher levels of task-involving behaviors from peers predicted mastery goal orientation. Participants with higher mastery goal orientation reported greater sport competence, self-esteem, and more enjoyment; enjoyment was the strongest predictor of intention to continue. These findings both emphasize the importance of peer relationships within sport on a variety of motivationally and psychologically salient outcomes and provide direction for the development of training programs targeted to create positive and healthy sport experiences.

Prompting methods are common amongst animal trainers, both novice and experts. However, there is little empirical evidence to demonstrate the strengths or weaknesses of common prompting procedures. The current study assessed the strengths and weaknesses during behavior acquisition of two prompting methods, luring and targeting. Luring placed an edible directly in front of the animal which guided the animal through the desired behavior. Targeting, however used a target, an arbitrary object the animal has been trained to touch, guide behavior. A cat was trained, using each method, to walk around a flower. Walking around the right flower pot was trained using luring and walking around the left flower pot was trained using targeting. After both behaviors were acquired, a delay cue method was designed to transfer stimulus control. Later a combination of a delay cue and prompt fading was used. During acquisition the luring method acquired the behavior of walking around a pot more quickly with consistently fewer errors. During stimulus transfer the cat began independently initiating the behavior earlier with the target trained behavior and produced more correct behaviors after the verbal cue. Luring appeared to produce the faster behavior, but after stimulus transfer it could be concluded that …

Multi-modal image fusion is an active research area with many civilian and military applications. Fusion is defined as strategic combination of information collected by various sensors from different locations or different types in order to obtain a better understanding of an observed scene or situation. Fusion of multi-modal images cannot be completed unless these two modalities are spatially aligned. In this research, I consider two important problems. Multi-modal, multi-perspective image registration and decision level fusion of multi-modal images. In particular, LiDAR and visual imagery. Multi-modal image registration is a difficult task due to the different semantic interpretation of features extracted from each modality. This problem is decoupled into three sub-problems. The first step is identification and extraction of common features. The second step is the determination of corresponding points. The third step consists of determining the registration transformation parameters. Traditional registration methods use low level features such as lines and corners. Using these features require an extensive optimization search in order to determine the corresponding points. Many methods use global positioning systems (GPS), and a calibrated camera in order to obtain an initial estimate of the camera parameters. The advantages of our work over the previous works are the following. …

In 1863, Fort Bascom was built along the Canadian River in the Eroded Plains of Territorial New Mexico. Its unique location placed it between the Comanches of Texas and the Comancheros of the Sangre de Cristo Mountains. This post was situated within Comanchería during the height of the United States Army's war against the Southern Plains Indians, yet it has garnered little attention. This study broadens the scholarly understanding of how the United States Army gained control of the Southwest by examining the role Fort Bascom played in this mission. This includes an exploration of the Canadian River Valley environment, an examination of the economic relationship that existed between the Southern Plains Indians and the mountain people of New Mexico, and an account of the daily life of soldiers posted to Fort Bascom. This dissertation thus provides an environmental and cultural history of the Canadian River Valley in New Mexico, a social history of the men stationed at Fort Bascom, and proof that the post played a key role in the Army's efforts to gain control of the Southern Plains Indians. This study argues that Fort Bascom should be recognized as Texas' northern-most frontier fort. Its men were closer to …

This dissertation contains two parts: Part I, which discusses the elegy of possessive intent, a subgenre of the contemporary American elegy; and Part II, Antigravity, a collection of poems. English elegies have been closely rooted to a specific grief, making the poems closer to occasional poems. The poet—or at least the poet’s speaker—seeks some kind of public consolation for (often) a private loss. The Americanized form does stray from the traditional elegy yet retains some of its characteristics. Some American elegies memorialize failed romantic relationships rather than the dead. In their memorials, these speakers seek a completion for the lack the broken relationship has created in the speakers’ lives. What they can’t replace, they substitute with something personal. As the contemporary poem becomes further removed from tradition, it’s no surprise that the elegy has evolved as well. Discussions of elegies have never ventured into the type of elegy that concerns itself with the sort of unacknowledged loss found in some contemporary American poems of unrequited love. These poems all have speakers who willfully refuse to acknowledge the loss of their love-objects and strive to maintain control/ownership of their beloveds even in the face of rejection.

In “Sounds for Adventurous Listeners,” I argue that Conover’s role in the dissemination of jazz through the Music USA Jazz Hour was more influential on an educational level than what literature on Conover currently provides. Chapter 2 begins with an examination of current studies regarding the role of jazz in Cold War diplomacy, the sociopolitical implications of avant-garde jazz and race, the convergence of fandom and propaganda, the promoter as facilitator of musical trends, and the influence of international radio during the Cold War. In chapter 3 I introduce the Friends of Music USA Newsletter and explain its function as a record of overseas jazz reception and a document that cohered a global network of fans. I then focus on avant-garde debates of the 1960s and discuss Conover’s role overseas and in the United States. Chapter 4 engages social purpose and jazz criticism in the 1960s. I discuss Conover’s philosophy on social responsibility, and how his contributions intersected with other relevant discourses on race on the eve of the civil rights movement. I argue that Conover embodied two personas: one as jazz critic and promoter in the United States, and the other as an international intermediary. In chapter 5 I …

The purpose of this study was to investigate the perceptions of Texas principals as to the degree to which their local school districts are meeting their ongoing professional development need. The study was conducted to analyze and describe the survey and interview responses of Texas principals as to their perceptions of the degree to which their local school districts provide learning experiences aligned with their needs. Texas principals’ perceptions regarding the characteristics of important and meaningful professional learning experiences were explored. The study included an analysis of the extent to which Texas principals perceive that the learning opportunities they are provided adequately meet those needs. Additionally, various factors influencing principals and their perceptions were examined. These factors included type of school, school setting, school system size, characteristics of students, and characteristics of the principals. The perceptions of school district staff development administrators were analyzed regarding topic importance, topic provision by the local district, and the usefulness of those topics. Finally, the perceptions of the principals and the staff development administrators were compared. Thirteen school districts participated in this study. Of the 273 principals surveyed, 155 completed the survey, yielding a return rate of 56.8%. One campus principal from each of …

Studies of affective forecasting examine people’s ability to predict (forecast) their emotional (affective) responses to future events. Affective forecasts underlie nearly all decisions people make and the actions they take. However, people engage in systematic cognitive errors when making affective forecasts and most often overestimate the intensity and duration of their emotional responses. Understanding the mechanisms that lead to affective forecasting errors (e.g., immune neglect) and examining the utility of methods for improving affective forecasting errors (e.g., surrogation) can provide highly valuable information for clinicians as they assist clients in determining their goals both for therapy and for life. The first purpose of the current study was to determine if affective forecasting errors due to immune neglect lead to misjudgments about the relative emotional impact of minor versus moderate negative experiences (i.e., trauma severity). The second purpose was to examine the utility of surrogation for improving affective forecasts. Potential interaction effects between these two variables were also examined. The current study utilized a 2 (Trauma Severity: minor, moderate) X 3 (Prediction Information: surrogation information only, simulation information only, both types of information) experimental design. Undergraduates were recruited via the SONA system and randomly assigned to one of the six experimental …

Despite socioeconomic disadvantages, less acculturated Mexican Americans tend to exhibit better mental health than their more acculturated counterparts. However, in the case of older Mexican American adults, research has demonstrated the opposite to be true (Gonzalez, Haan, & Hinton, 2001). A variable of interest potentially responsible for this difference is social support. Thus, the current study proposed to investigate the mediation and moderation effects that social support has on the relationship between acculturation and depression in older Mexican American adults age 60 or older. Data from the Health and Retirement Study (HRS) was analyzed. Results showed that the mediating effect of contact with one’s children (-.109*) and the moderating effect of total social support and contact with one’s children (-.127*; -.103*) were statistically significant in the relationship between acculturation and depression. Although these effects are small they may still hold important implications for better understanding this population.
