Diatom Proteomics Reveals Unique Acclimation Strategies To Mitigate Fe Limitation, Brook L. Nunn, Jessica F. Faux, Anna A. Hippman, Maria T. Maldonado, H. Rodger Harvey, David R. Goodlett, Philip W. Boyd, Robert F. Strzepek

OES Faculty Publications

Phytoplankton growth rates are limited by the supply of iron (Fe) in approximately one third of the open ocean, with major implications for carbon dioxide sequestration and carbon (C) biogeochemistry. To date, understanding how alteration of Fe supply changes phytoplankton physiology has focused on traditional metrics such as growth rate, elemental composition, and biophysical measurements such as photosynthetic competence (Fv/Fm). Researchers have subsequently employed transcriptomics to probe relationships between changes in Fe supply and phytoplankton physiology. Recently, studies have investigated longer-term (i.e. following acclimation) responses of phytoplankton to various Fe conditions. In the present study, the coastal diatom, Thalassiosira pseudonana, …

Special Education Teacher Retention: The Relationship Between Mentoring, Job Satisfaction And The Retention Of Special Education Teachers, Angela Horrison-Collier

College of Graduate Studies: Theses & Dissertations

The causes of the teacher shortage are complex; however, the retention of special education teachers is a significant contributor to this shortage. Some research has indicated that up to 9.3 % of special education teachers leave the field at the end of their first year of teaching and 7.4 % move to general education yearly. Therefore, school districts face a continuous cycle of recruitment, hiring, and induction. Because of the pivotal value of retention, school districts and site level education leaders must take proactive steps to reduce the retention rate. The research on teacher retention indicates factors such as salary, …

Total Lightning As An Indicator Of Convectively Induced Turbulence Threat To Aviation Interests, Ryan Rogers

Theses

The FAA recommends that aircraft avoid thunderstorms by a minimum of 20 nautical miles horizontally. When this buffer is not maintained the chance of an aircraft experiencing turbulence is increased. The presence of lightning in a convective cell gives some indication of its turbulence potential so locations of lightning flash initiations are used to highlight updraft regions where convectively induced turbulence is generated. Data from the North Alabama Lightning Mapping Array (NALMA) serves as a proxy for Geostationary Lightning Mapper (GLM) total lightning capability. GLM proxy data are used to investigate the impact of 8x8 km resolution on lightning-turbulence relationships. …

Selective Phosphoinositide 3-Kinase Inhibition Via Natural Products : A Computational Study, David Jackson

Theses

PI3K (phosphoinositide 3-kinase) is responsible for a large number of signaling pathways involved in a range of conditions ranging from allergic response to tumor growth. Current research is still being done to find novel selective inhibitors for the different isoforms of PI3K. This research was performed in order to find new selective inhibitors from the world of natural products. A list of known pharmaceutical inhibitors was run in order to compare how well the natural product inhibitors performed. Eleven selective and semi-selective inhibitors were found to inhibit PI3K. The alkaloids found include berberine, chelerythine, isaindigotone, noscapine, pseudocoptisine, and tetrandrine. The …

Greedy Hierarchical Binary Classifiers For Multi-Class Classification Of Biological Data, Salma Begum

Theses

Multi-class classification is an important and challenging problem for biological data classification as biological datasets may generate data that may belong to multiple classes not just due to the presence of different classes but also due to the evolutionary phases of biological experiments. Typical methods for dealing with multi-class classification use a powerful single classifier such as neural networks to classify the data into one of many classes. Alternatively, the binary classifiers are used in one-versus-one (OVO) and one-versus-all (OVA) classifier schemes for multi-class classification. However, it is not clear whether OVO or OVA yield good performance results. In this …

Forest Transitions And Environmental Policy In The Western Ghats Of India, Melanie Phillips

Theses

For several decades the amount of forest cover worldwide has followed a declining trend. Recently, developing countries such as India have begun social and political programs to support an opposite trend of forest restoration. The cause of this positive forest transition varies in each nation. This study shows the impact of recent developments in state-local forestry management programs on forest cover in the Western Ghats of India from 2001-2011. Using GIS and remote sensing technology this study analyzes recent patterns in forest extent and health in seven districts within the Western Ghats. Currently there is a serious lack of quantitative …

Biochemical Characterization Of Peptidyl-Trna Hydrolase 1 From S. Aureus And B. Cereus, Kasey Taylor Creel

Theses

The critical need for new antibiotics and antibiotic targets is of great urgency to our society in order to combat drug resistance and ward off pathogenic bacteria. One new antibacterial target is the essential bacterial enzyme Peptidyl-tRNA Hydrolase I (Pth1). In the course of protein elongation, ribosomes stall and release peptidyl-tRNA. Peptidyl-tRNA hydrolase 1 releases the tRNA from the peptidyl-tRNA, allowing the tRNA to be recycled in the cell. Without Pthl hydrolysis, peptidyl-tRNAs will accumulate, slowing down and eventually stopping protein synthesis, leading to cell death. The fact that Pthl is an essential gene in E. coli suggests that its …

Performance And Energy Efficiency Of Common Compression/Decompression Utilities : An Experimental Study In Mobile And Workstation Computer Platforms, Armen A. Dzhagaryan

Theses

Lossless compression and decompression are routinely used in mobile and workstation computer systems to reduce the costs of communicating and storing data. This research presents the results of a measurement-based experimental evaluation of common compression and decompression utilities running on several plat-forms of varying hardware complexity representing current mobile and workstation systems. The evaluation involves characterization of the compression and decompression utilities in a multidimensional space encompassing the compression ratio, compression and decompression throughput, and energy efficiency. Different use scenarios and conditioning typical for modern mobile and workstation computing platforms are considered. The study observes a wide variety of energy …

Generation Of Radio Frequency Induced Metastable Xenon As A Gain Medium For Diode Pumped Rare Gas Laser Systems, Jacqueline Marie Andreozzi

Theses

The pursuit of novel, hybrid methods of achieving lasing from the rare gases has recently been a topic of interest in the field of high energy laser systems. This investigation presents the construction and execution of an experimental setup designed to generate metastable xenon (Xe*) to determine its potential to perform as a high power laser gain medium in a similar capacity as the alkali metals in Diode Pumped Alkali Lasers. A capacitively coupled radio frequency discharge was used to light plasma from naturally abundant xenon, thus exciting the 6s[3/2]₂ metastable state. The metastable xenon was probed with a …

Vision Based Control Of Autonomous Underwater Vehicles, Karansingh Thakur

Theses

Vision based control (Visual Servoing) of an autonomous 6-DOF vehicle is considered in this thesis. The vehicle is to be navigated underwater using the cameras mounted on its body. With the new developed algorithm, the need for underwater GPS, Tilt Sensors and other costly devices is eliminated. The new algorithm overcomes the shortcomings of the existing algorithms, PBVS (Position-Based Visual Servoing) and IBVS (Image-Based Visual Servoing). The underwater vehicle is navigated using the image feedback obtained from the cameras. These image features are fed to the control system on the vehicle which in turn generates the desired motion. Simulations runs …

To Sotl Or Not To Sotl?, Diana Sturges

Health Sciences & Kinesiology: Faculty Publications

Excerpt: "To be, or not to be, that is the question" is one of the most famous lines from Shakespeare’s play Hamlet. As a soliloquy, Hamlet's speech represents a monologue of his thoughts and feelings and addresses existential questions. It is generally accepted that in his speech Hamlet is wondering whether he should choose between life and death. Life seems to be full of hardships, yet there is uncertainty at what lies beyond life, what happens after death? It is assumed that the audience (if there is one) would not hear the speaker, however, Hamlet-the character of the play …

In The Absence Of Scrutiny: Narratives Of Probable Cause, Mitu Gulati, Jack Knight, David F. Levi

Faculty Scholarship

This Article reports on a set of roughly thirty interviews with federal magistrate judges. The focus of the interviews was the impact of the Supreme Court case, United States v. Leon, on the behavior of magistrate judges. Leon, famously, put in place the "good faith" exception for faulty warrants that were obtained by the officers in good faith. The insertion of this exception diminished significantly the incentive for defendants to challenge problematic warrant grants. That effect, in turn, could have diminished the incentive for magistrate judge scrutiny of the warrants at the front end of the process. We do not …

The Unraveling Of The Private Consensus, Justin Kh Tse

Research Collection School of Social Sciences

The Asian American Open Letter to the Evangelical Church was a key moment in the unraveling of the private consensus in American evangelicalism in 2013. What I call the “private consensus” is an implied agreement among evangelical Protestants in America that churches, parachurch organizations, and religious institutions should conduct matters privately. In fact, it might go as far as to say that individual Christians should act in private, away from the public eye, especially the media. When Christian matters become public, so the argument goes, they become distorted. Consequently, Christians are encouraged to operate at a “direct and personal” level, …

Mapping Dissent: The Responsibility To Protect And Its State Critics, Patrick Quinton-Brown

Research Collection School of Social Sciences

Addressing dissent, also known as ‘rejectionism’, will broaden and deepen the global consensus on the Responsibility to Protect (R2P) principle. However, how should scholars understand the objections raised by state critics? To answer this question, I analyse R2P opposition as presented in official UN transcripts, voting records, and resolutions. The article reveals that six related themes of dissent exist with varying degrees of emphasis amongst opponents. Conventional depictions of R2P opposition, such as the absolute sovereignty or North vs. South explanations, are therefore inadequate representations of the diverse range of arguments employed by dissenters. Ultimately, I conclude that in order …

Subjective Well-Being, William Tov, Ed Diener

Research Collection School of Social Sciences

The cross-cultural importance of happiness and contentment can be inferred from their emergence in philosophical discussions across many cultural traditions. We begin by focusing on similarities, noting what has been found to correlate with the components of SWB across most cultures. Subjective well being (SWB) involves the various ways that people evaluate and experience their lives. In many ways, the term is synonymous with the everyday notion of happiness – positive feelings are an important aspect of well being. Cross-cultural similarities are important because they highlight our common humanity and hint at which factors may be fundamental to wellbeing. Next, …

Secularity, Religion And The Possibilities For Religious Citizenship, Lyn Parker, Chang Yau Hoon

Research Collection School of Social Sciences

Scholarly predictions of the secularization of the world have proven premature. We see a heterogeneous world in which religion remains a significant and vital social and political force. This paper reflects critically upon secularization theory in order to see how scholars can productively respond to the, at least partly, religious condition of the world at the beginning of the twenty first century. We note that conventional multiculturalism theory and policy neglects religion, and argue the need for a reconceptualization of understanding of religion and secularity, particularly in a context of multicultural citizenship — such as in Australia and Indonesia. We …

The Biology And Taxonomy Of Head And Body Lice— Implications For Louse-Borne Disease Prevention, Denise L. Bonilla, Lance A. Durden, Marina E. Eremeeva, Gregory A. Dasch

Environmental Health Sciences: Faculty Publications

Sucking lice (Phthiraptera: Anoplura) are obligate blood-feeding ectoparasites of placental mammals including humans. Worldwide, more than 550 species have been described and many are specific to a particular host species of mammal [1]. Three taxa uniquely parasitize humans: the head louse, body louse, and crab (pubic) louse. The body louse, in particular, has epidemiological importance because it is a vector of the causative agents of three important human diseases: epidemic typhus, trench fever, and louse-borne relapsing fever. Since the advent of antibiotics and more effective body louse control measures in the 1940s, these diseases have markedly diminished in incidence. However, …

North American Indigenous Adolescent Substance Use, Melissa Walls, Kelley J. Sittner Hartshorn, Les B. Whitbeck

Department of Sociology: Faculty Publications

Objectives—To investigate growth in problem drinking and monthly marijuana use among North American Indigenous adolescents from the upper Midwest and Canada.

Methods—Panel data from a community-based participatory research project includes responses from 619 adolescents residing on or near 7 different reservations/reserves. All respondents were members of the same Indigenous cultural group.

Results—Rates of problem drinking and monthly marijuana use increased steadily across the adolescent years, with fastest growth occurring in early adolescence (before age 15). In general, female participants reported higher rates of substance use prior to age 15; however, male reports of use surpassed those of females in later …

The Importance Of Social Cues For Discretionary Health Services Utilization: The Case Of Infertility, Arthur L. Greil, Karina M. Shreffler, Katherine M. Johnson, Julia Mcquillan, Kathleen S. Slauson-Blevins

Department of Sociology: Faculty Publications

Infertility is a discretionary health condition; although it carries with it important life course implications, treatment is rarely necessary for health reasons. Sociological theories of medical help-seeking emphasize demographic factors, perceived need, and enabling conditions in health services utilization, but we find that social cues are also strongly associated with health services utilization for infertility. Adjusted for conventional predictors of medical help-seeking, several social cue indicators have significant associations with utilization, including having friends and family with children, perceiving infertility stigma, and having a partner and/or family member who encourages treatment. Perceived need accounts for the largest portion of the …

From College Student To Change Agent: A Triadic Model Of Self-Efficacy, Attribution, And Appraisal, Joshua M. Garrin

Journal of Sustainable Social Impact

Beyond their newfound emancipation and opportunities for self-discovery, college students in the young adult stage of development are expected to achieve balance between their autonomous new world and the impending pressures of postgraduation life. The college student must not only reconcile issues related to identity formation, goal pursuits, and career exploration, but is expected to begin the process of identifying and developing the skills required to address salient social themes. How students establish competency beliefs, negotiate controllability over future outcomes, and appraise challenges have deep implications in their capacity to discover their social change “voice.” The following discussion proposes a …

An Innovative Approach To Action Research In Family Violence Prevention, Linnaya M. Graf, Nancy K. Rea, William M. Barkley

Journal of Sustainable Social Impact

Violence prevention remains a priority in the current public health agenda because of continuing high rates and debilitating effects of violence that exist across the globe (U.S. Department of Health and Human Services, Administration on Children, Youth and Families [USDHHS-ACF], 2009; World Health Organization [WHO], 2013). This article presents the use of an innovative qualitative study developed from community action research methods in the area of family violence. By applying the combined framework of force field analysis (Lewin, 1958) and the public health model (Centers for Disease Control, 2002; Knox & Aspy, 2011), the current study identified factors that positively …

Do Non-Response Follow-Ups Improve Or Reduce Data Quality?: A Review Of The Existing Literature, Kristen Olson

Department of Sociology: Faculty Publications

The paper systematically reviews existing literature on the relationship between the level of effort to recruit a sampled person and the measurement quality of survey data. Hypotheses proposed for this relationship are reviewed. Empirical findings for the relationship between level of effort as measured by paradata (the number of follow-up attempts, refusal conversion and time in the field) and question-specific item non-response rates, aggregate measures of item non-response rates, response accuracy and various measurement errors on attitudinal questions are examined through a qualitative review.

Paradata For Nonresponse Adjustment, Kristen Olson

Department of Sociology: Faculty Publications

Survey researchers and practitioners use nonresponse adjustment weights to mitigate the effects of survey nonresponse on sample estimates. One challenge in creating these weights is finding useful auxiliary data that predict both the probability of participating in the survey and the survey variables of interest. This article reviews the use of paradata for nonresponse adjustment. Five different types of paradata are considered: neighborhood observations, observations of the sampled housing unit, observations of persons in the sampled housing unit, call records, and observations about the interviewer-householder interaction. Empirical evidence about the predictive value of these paradata for predicting both participation and …
