Self-Directedness In Foreign Language Learners: A Phenomenological Study Of College Students And Foreign Language Instructors, Sueid Fauaze Moreira

Theses and Dissertations

The intent of the qualitative research was to investigate if students experience self-directedness when taking foreign language classes at the college level. The research was based on learners' perspectives of the phenomenon both verifying the use of self-directedness among learners and understanding the paradigms of self-direction. Guided by scholarly research, the construct elements for the research were a) Characteristics of Instruction, b) Characteristic of Learner, and c) Self-Directedness. Four groups of students were identified in the study. Individual students' interview responses revealed that their perceived needs varied according to their degree seeking and career goals. Interview data combined with scores …

Systematic Analysis Of Nutritional Components, Cell Wall Chemical Features And Potential Pathway(S) Of Assimilate Transport In The Developing Pods And Seeds Of Medicago Truncatula, Alka Sharma

Theses and Dissertations

Medicago truncatula is a model species for legume studies. Despite the great advances in the study of M. truncatula and development of a vast array of genetic tools and genomic resources, there is a lack of knowledge regarding the nutrient movement and accumulation in its pods and seeds. This study used a combination of the microscopic analysis, histochemical localization and the fluorescent tracers to identify the cellular course and location of nutrient movement. Temporal histochemical localization revealed that the longer duration of the accumulation of protein bodies and lipid droplets combined with the high hexoses concentration in seed apoplasm might …

Untargeted Metabolite Profiling Using A Multi-Way Decomposition Method, Minho Chae

Theses and Dissertations

Although gas chromatograpy-mass spectrometry (GC-MS) is a mature technology for profiling primary metabolites, analyzing those datasets in a large-scale and high-throughput manner is a great challenge because of the complex nature of the data. There is often non-linear inter-run variance in the retention time between runs, making it difficult to identify corresponding peaks among multiple runs. Moreover, peaks are rarely homogeneous. They often contain systematic signals, i.e., background, or non-systematic signals, i.e., noise, and many peaks comprise multiple co-eluting or overlapping components. Thus, identifying all the pure components in all of the peaks from the entire dataset, and comparing them …

Relational Aggression, Intimate Partner Violence, And Gender: An Exploratory Analysis, Emily M. Wright, Michael L. Benson

Criminology and Criminal Justice Faculty Publications

This study explores the effects of romantic relational aggression on intimate partner violence. The concept of relational aggression denotes a type of nonphysical aggression that is specific to relationships and that has only recently been recognized in the psychological literature. Using responses to the Conflict Tactics Scale from adults participating in the Project on Human Development in Chicago Neighborhoods, romantic relational aggression is examined with regard to male and female intimate partner violence perpetration and victimization. Results indicate that romantic relational aggression is a predictor of partner violence perpetration and victimization among both males and females.

A Bioinformatics & Computational Biology Approach To Supervised Selection And Prognostic Marker Identification For Malignant Astrocytic Glioma Patients, Vinay Ravindrakumar Raj

Theses and Dissertations

Malignant astrocytic gliomas, like Glioblastoma Multiforme and Anaplastic Astrocytoma, are among the deadliest forms of brain tumors with varying periods of survival. Currently, the risk of a glioma patient is mostly measured by prognostic models with clinical prognostic markers and has limited success. In this study a Bioinformatics & Computational Biology approach to identify candidate prognostic markers from a combination of clinical, genetic and gene expression variables (related to multiple significant pathways targeted by classical genetic alterations) involved in malignant glioma progression, was developed to explain variation in survival. The initial selection of molecular variables for prognosis modeling was done …

Fetal Breathing Movement And Its Distinctive Characteristics In Bio-Magnetic Data, Umit Deniz Ulusar

Theses and Dissertations

Magnetoencephalography (MEG) is widely used to study magnetic fields generated by the electrical activity of the human brain and can also be applied for fetal neurological health assessment. The fetal MEG (fMEG) signals are often contaminated with other bio-magnetic signals such as fetal breathing movement (FBM), which acts as an interfering factor for fetal neurological signals. This study was carried out to identify the bio-magnetic signals pertinent to the FBM. The fMEG signals were captured using superconducting quantum interference devices (SQUIDs) and the FBMs were recorded by an ultrasound-based video technique. The simultaneous recording is challenging since SQUIDs are extremely …

Signal Detection Framework Using Semantic Text Mining Techniques, Sithu D. Sudarsan

Theses and Dissertations

Signal detection is a challenging task for regulatory and intelligence agencies. Subject matter experts in those agencies analyze documents, generally containing narrative text in a time bound manner for signals by identification, evaluation and confirmation, leading to follow-up action e.g., recalling a defective product or public advisory for potential flu outbreak. Technical challenges to achieve effective signal detection include mining unstructured data, increasing document collections, and presence of multi-domain vocabulary. Lack of annotation and multi-domain vocabulary makes traditional semantic web mining ineffective. Use of heuristics to enhance bag-of-words type text mining to semantic text mining is a novel idea attempted …

Unusually Conductive Carbon-Inherently Conducting Polymer (Icp) Composites: Synthesis And Characterization, Shawn Edward Bourdo

Theses and Dissertations

Two groups of materials that have recently come to the forefront of research initiatives are carbon allotropes, especially nanotubes, and conducting polymers-more specifically inherently conducting polymers. The terms conducting polymers and inherently conducting polymers sometimes are used interchangeably without fully acknowledging a major difference in these terms. Conducting polymers (CPs) and inherently conducting polymers (ICPs) are both polymeric materials that conduct electricity, but the difference lies in how each of these materials conducts electricity. For CPs of the past, an electrically conductive filler such as metal particles, carbon black, or graphite would be blended into a polymer (insulator) allowing for …

Antifolate Modulators Of Amp-Activated Protein Kinase Signaling As Cancer Therapeutics, Scott Rothbart

Theses and Dissertations

Since its discovery, it was appreciated that the antifolate pemetrexed had multiple targets within folate metabolism. This laboratory was instrumental in showing that pemetrexed elicited its primary action as a thymidylate synthase inhibitor. Unusual for an antifolate, pemetrexed showed significant clinical activity against malignant pleural mesothelioma and non-small cell lung cancer. Accordingly, the FDA recently issued first-line approvals for pemetrexed in these diseases, leading us to question whether the effects of pemetrexed on other folate-dependent targets could explain this atypical clinical activity of the drug. Studies in this dissertation showed that in addition to thymidylate synthase inhibition, pemetrexed was also …

B Cell Adam10 Activity Is Increased By Kainate Receptor Activation: Potential Role Of This Pathway In Th2 Immunity And Cancer, Jamie Sturgill

Theses and Dissertations

CD23 has long been appreciated to be a natural, negative regulator of IgE synthesis. This understanding is due in part to animal models in which CD23 deficient or CD23 transgenic animals display exacerbated or reduced IgE levels respectively. Interestingly, CD23 is susceptible to proteolytic cleavage from the cell surface. When this occurs, CD23 loses its regulatory capability and the solubilized form can lead to pro-inflammatory events through its cytokinergic activity on macrophages. Thus, targeting this specific cleavage would be beneficial to the control of allergic disease by stabilizing CD23 at the cell surface. Inhibitor studies performed by our group as …

Predicting Stability Of Alpha-Helical, Orthogonal-Bundle Proteins On Surfaces, Shuai Wei, Thomas A. Knotts

Faculty Publications

The interaction of proteins with surfaces is a key phenomenon in many applications, but current understanding of the biophysics involved is lacking. At present, rational design of such emerging technologies is difficult as no methods or theories exist that correctly predict how surfaces influence protein behavior. Using molecular simulation and a coarse-grain model, this study illustrates for the first time that stability of proteins on surfaces can be correlated with tertiary structural elements for alpha-helical, orthogonal-bundle proteins. Results show that several factors contribute to stability on surfaces including the nature of the loop region where the tether is placed and …

Understanding Undergraduate Research Experiences Through The Lens Of Problem-Based Learning: Implications For Curriculum Translation, Olga Pierrakos, Anna Zilberberg, Robin Anderson

Interdisciplinary Journal of Problem-Based Learning

There has been criticism about STEM education not focusing enough on problem solving, especially in authentic real-world contexts which are most often associated to ill-structured domains. To improve education, it is essential that curricula bring students to high levels of cognitive development by exposing them to authentic problems. Problem-based learning (PBL) is a student-centered pedagogy that offers a strong framework upon which to build a curriculum to teach students essential problem solving skills. An authentic problem solving experience, which is highly valued and promoted outside of the classroom, yet almost non-existent in the classroom is undergraduate research (UR). Herein, the …

A Comparison Of Five Reinforcement Schedules For Use In Contingency Management-Based Treatment Of Methamphetamine Abuse, John M. Roll, Alice Huber, Ruthlyn Sodano, Joy E. Chudzynski, Eugene Moynier, Steve Shoptaw

The Psychological Record

One variation of contingency management involves providing vouchers with monetary value for the provision of a biological sample indicating no recent drug use. These vouchers can be exchanged for goods or services. The schedule with which the vouchers are disbursed has been studied and results suggest that those schedules that incorporate escalating magnitude of reinforcement for consecutive instances of abstinence and a reset contingency, which reduces the value of the vouchers for instances of use, seem to provide the best treatment outcome. In th is paper we explore several other scheduling arrangements while using the escalating schedule with a reset …

The Role Of Puf3p And Puf4p In The Regulation Of Mrna Decay In Yeast Saccharomyces Cerevisiae, Florencia Andrea Lopez Leban

Dissertations

Proper regulation of gene expression at a cellular level is required in all organisms for their successful adaptation and survival to physiological or environmental changes. In eukaryotes, a convenient way of regulating gene expression is achieved by post-transcriptionally adjusting the decay rates of different mRNAs. The Puf family of proteins in yeast belong to a widespread group of eukaryotic RNA-binding proteins that regulate the lifespans of target mRNAs by sequence specifically binding to 3' untranslated regions (UTRs) and modulating their decay rates. For example, the yeast Puf3 protein binds the COX17 3' UTR, stimulating its deadenylation and subsequent decay. However, …

Regarding Scientific Significance, P.D. Magnus

Philosophy Faculty Scholarship

In Science, Truth, and Democracy, Philip Kitcher introduces significance graphs (structures that illustrate how and which questions are significant) and well ordered science (a norm defined by an imagined process of ideal deliberation). Jeremy Simon has argued that these two parts of Kitcher's account are intimately connected. In this paper, I argue that the connection between significance graphs and well-ordered science is rather more complicated. I survey three objections to Kitcher's account, two from Simon and a third by analogy with similar positions in ethics. This paper aims to show that Kitcher's account relies on some questions being ones about …

Dipolar Cortico-Muscular Electrical Stimulation: A Novel Method That Enhances Motor Function In Both - Normal And Spinal Cord Injured Mice, Zaghloul Ahmed

Publications and Research

Background Electrical stimulation of the central and peripheral nervous systems is a common tool that is used to improve functional recovery after neuronal injury. Methods Here we described a new configuration of electrical stimulation as it was tested in anesthetized control and spinal cord injury (SCI) mice. Constant voltage output was delivered through two electrodes. While the negative voltage output (ranging from -1.8 to -2.6 V) was delivered to the muscle via transverse wire electrodes (diameter, 500 μm) located at opposite ends of the muscle, the positive output (ranging from + 2.4 to +3.2 V) was delivered to the primary …

The Terebridae And Teretoxins: Combining Phylogeny And Anatomy For Concerted Discovery Of Bioactive Compounds, Nicolas Puillandre, Mandë Holford

Publications and Research

The Conoidea superfamily, comprised of cone snails, terebrids, and turrids, is an exceptionally promising group for the discovery of natural peptide toxins. The potential of conoidean toxins has been realized with the distribution of the first Conus (cone snail) drug, Prialt (ziconotide), an analgesic used to alleviate chronic pain in HIV and cancer patients. Cone snail toxins (conotoxins) are highly variable, a consequence of a high mutation rate associated to duplication events and positive selection. As Conus and terebrids diverged in the early Paleocene, the toxins from terebrids (teretoxins) may demonstrate highly divergent and unique functionalities. Recent analyses of the …

An Evaluation Of Water Treatment Technologies Piloted At Lanl To Improve Cooling Tower Water Efficiency., Patricia Vardaro-Charles

Water Resources Professional Project Reports

This paper presents an evaluation of three technologies piloted at Los Alamos National Laboratory (LANL) for improving cooling tower water efficiency. High silica content (average of 88 mg/L) in LANL source water requires frequent blow down in cooling tower systems to avoid accumulation of silica scale on heat transfer surfaces. At concentrations above 150 mg/L, silica scaling on heat transfer surfaces can occur to the extent scale causes a reduction in cooling effectiveness and can lead to system shutdown. The pilot project evaluated two chemical treatment processes and two silica removal processes for a period of 4 months in a …
