A Bioinformatics Method For Identifying Rna Structures Within Human Cells, Stephen Donald Huff

Physics Seminars

Single-stranded, negative-sense RNA (ssRNA-) serves many varied roles within the eukaryotic cell. Currently known examples include snRNA (short nuclear), snoRNA (short nucleolar), tRNA (transfer), siRNA (silencing), miRNA (micro), and others [1,2]. Unknown examples are currently being studied, also, including the long, non-coding ssRNA- found in the nuclear paraspeckle, a component of unknown function located within the eukaryotic nucleus and comprised of ssRNA- sequences transcribed from so-called ‘junk’ DNA [3,4]. While a growing list of confirmed physiological functions have been attributed to ssRNA-, additional roles likely exist and have yet to be discovered. Further, since ssRNA- is known to bind to …

Introduction To Empowered Partnerships: Community-Based Participatory Action Research For Environmental Justice, Christopher M. Bacon, Saneta Devuono-Powell, Mary Louise Frampton, Tony Lopresti, Camille Pannu

Environmental Studies and Sciences

This article introduces a special section on empowered partnerships that deepens a dialogue initiated during the 2010 symposium titled EmPowered Partnerships: Community-Based Participatory Action Research for Environmental Justice. The articles in this section will be divided between issues 1 and 2 of the Journal. After briefly reviewing the definitions and the steps associated with community-based participatory action research (CBPAR), we identify the synergies connecting the underlying principles and values of the environmental justice (EJ) movement and CBPAR. The principles-based comparison is part of an ongoing effort to craft a framework that produces research partnerships that are simultaneously more responsive to …

Molecular Mechanisms Of Disease-Causing Missense Mutations, Shannon Stefl, Hafumi Nishi, Marharyta Petukh, Anna R. Panchenko, Emil Alexov

Publications

Genetic variations resulting in a change of amino acid sequence can have a dramatic effect on stability, hydrogen bond network, conformational dynamics, activity and many other physiologically important properties of proteins. The substitutions of only one residue in a protein sequence, so-called missense mutations, can be related to many pathological conditions, and may influence susceptibility to disease and drug treatment. The plausible effects of missense mutations range from affecting the macromolecular stability to perturbing macromolecular interactions and cellular localization. Here we review the individual cases and genome-wide studies which illustrate the association between missense mutations and diseases. In addition we …

Finding Specifications Of While Statements Using Patterns, Aditi Barua, Yoonsik Cheon

Departmental Technical Reports (CS)

A formal correctness proof of code containing loops such as while statements typically uses the technique of proof-by-induction, and often the most difficult part of carrying out an inductive proof is formulating a correct induction hypothesis, a specification for a loop statement. An incorrect induction hypothesis will surely lead to a proof failure. In this paper we propose a systematic way for identifying specifications of while statements. The key idea of our approach is to categorize and document common patterns of while statements along with their specifications. This is based on our observation that similarly-structured while statements frequently have similarly-structured …

Student Success And Perceptions Of Course Satisfaction In Face-To-Face, Hybrid, And Online Sections Of Introductory Biology Classes At Three, Open Enrollment, Two-Year Colleges In Southern Missouri, Joyce Diane Hill

Dissertations

Introductory biology courses at two-year, open enrollment colleges in America are presented in a variety of different course delivery formats. Traditionally, most students have enrolled in seated or face-to-face (F2F) lectures and laboratories. There is increased demand for courses presented online or in a hybrid format, although some studies report higher attrition rates, and lower grades for these course delivery formats. The purpose of this study was to examine if there were academic differences among F2F, hybrid, or online introductory biology courses by analyzing pre-course and post-course assessment scores, final grades, attrition rates, and students’ perceptions of course satisfaction. This …

Identifying And Describing The Network Of Health, Education, And Social Service Non-Profit Organizations In Southern Nevada, Shannon M. Monnat, Anna Smedley

Lincy Institute Reports and Briefs

Many of the economic, social, and demographic issues facing southern Nevada are dynamic and interrelated, requiring a coordinated approach on the part of southern Nevada’s non‐profit community. The coordination of services, skills, and talents enables community needs to be addressed in ways that exceed the scope and capacity of any single organization. With the increasing desire of funding organizations to support collaborative efforts, maintaining sustainable connections between southern Nevada’s non‐profit organizations is needed now more than ever before.

This is the first comprehensive study of southern Nevada’s health, education, and social service non‐profit network. Via a web‐based survey of nearly …

Dexterous Hexrotor Uav Platform, Guangying Jiang

Electronic Theses and Dissertations

Mobile manipulation is a hot area of study in robotics as it unites the two classes of robots: locomotors and manipulators. An emerging niche in the field of mobile manipulation is aerial mobile manipulation. Although there has been a fair amount of study of free-flying satellites with graspers, the more recent trend has been to outfit UAVs with graspers to assist various manipulation tasks. While this recent work has yielded impressive results, it is hampered by a lack of appropriate testbeds for aerial mobile manipulation, similar to the state of ground-based mobile manipulation a decade ago. Typical helicopters or quadrotors …

Alliances And Preferences: Party System Institutionalization's Potentially Intervening Role On Pre-Election Cooperation In Australia, Fiji, And Papua New Guinea, Lee T. Barrow

Electronic Theses and Dissertations

This research project examines the intervening role of party system institutionalization in determining the effect of electoral rules on the behavior of political parties. Highly institutionalized systems differ across multiple dimensions--supply stability, volatility of results, and rootedness of parties--from fluid systems. Party behavior can be depicted rationally as a response to both institutional incentives and the historical and sociological context of a nation's party system. Electoral incentives promoting certain types of party behavior can be negated by party system mechanics that deter those behaviors. The research uses a medium-N structured, focused comparison of elections from Australia, Fiji, and Papua New …

Defects And Dark Current In Organic Photovoltaics And Impacts On Device Physics, Xin Jiang

Electronic Theses and Dissertations

In this dissertation, we discussed the shape, energy level and density of defects in Organic Photovoltaic (OPV) devices by both theoretical and experimental methods. The energy band structure and intrinsic junctions of general standard and inverted OPV devices are investigated in detail. Transportation of separated holes and electrons in both structures are well analyzed. In chapter II, we developed a Monte-Carlo model to simulate charge transport process in organic materials. Marcus theory is applied to calculate the carrier transfer rate to build up hopping process in ideal lattices. Results of this model showed several properties of carriers regarding mobility, reorganization …

Semantics-Empowered Big Data Processing With Applications, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

We discuss the nature of Big Data and address the role of semantics in analyzing and processing Big Data that arises in the context of Physical-Cyber-Social Systems. We organize our research around the Five Vs of Big Data, where four of the Vs are harnessed to produce the fifth V - value. To handle the challenge of Volume, we advocate semantic perception that can convert low-level observational data to higher-level abstractions more suitable for decision-making. To handle the challenge of Variety, we resort to the use of semantic models and annotations of data so that much of the intelligent processing …

Molecular Detection Of Culture-Confirmed Bacterial Bloodstream Infections With Limited Enrichment Time, Miranda S. Moore, Chase D. Mccann, Jeanne Jordan

Epidemiology Faculty Publications

Conventional blood culturing using automated instrumentation with phenotypic identification requires a significant amount of time to generate results. This study investigated the speed and accuracy of results generated using PCR and pyrosequencing compared to the time required to obtain Gram stain results and final culture identification for cases of culture-confirmed bloodstream infections. Research and physician-ordered blood cultures were drawn concurrently. Aliquots of the incubating research blood culture fluid were removed hourly between 5 and 8 h, at 24 h, and again at 5 days. DNA was extracted from these 6 time point aliquots and analyzed by PCR and pyrosequencing for …

Currently there are definitions from many agencies and research societies defining “bioinformatics” as deriving knowledge from computational analysis of large volumes of biological and biomedical data. Should this be the bioinformatics research focus? We will discuss this issue in this review article. We would like to promote the idea of supporting human-infrastructure (HI) with no-boundary thinking (NT) in bioinformatics (HINT).

An Interface-Capturing Regularization Method For Solving The Equations For Two-Fluid Mixtures, Jian Du, Robert D. Guy, Aaron L. Fogelson, Grady B. Wright, James P. Keener

Mathematics Faculty Publications and Presentations

Many problems in biology involve gels which are mixtures composed of a polymer network permeated by a fluid solvent (water). The two-fluid model is a widely used approach to described gel mechanics, in which both network and solvent coexist at each point of space and their relative abundance is described by their volume fractions. Each phase is modeled as a continuum with its own velocity and constitutive law. In some biological applications, free boundaries separate regions of gel and regions of pure solvent, resulting in a degenerate network momentum equation where the network volume fraction vanishes. To overcome this difficulty, …

Snapshots Issue 2: Excellence And Equity, Sue Thomson

Snapshots

Australia’s performance on PIRLS was not as high as might have been thought, given that our students generally perform well on PISA reading literacy. However there is also a wide gap in achievement on PISA between students from a disadvantaged background and students from an affluent background. While some students in disadvantaged schools perform well, and some students in affluent schools perform poorly, one way for Australia to improve its performance on international assessments is to improve the performance of all students, particularly those from disadvantaged backgrounds.

Mathematical Misconceptions Of A Different Kind: Women Preservice Teachers’ Working Theories Of Mathematics Teaching, Kathleen Jablon Stoehr, Kathy Carter

Teacher Education

Mathematical anxiety and confidence in women who are entering the elementary teaching field is a subject that has captured the interest of mathematics teacher educators. Previous research has revealed that women who pursue elementary teaching careers are often individuals who themselves have confronted anxiety and low confidence in mathematics during their own K-12 experiences (Brady & Bowd, 2006; McGlynn-Stewart, 2010; Sloan, 2010). Prior studies in mathematics education reveal that individuals’ experiences with mathematics shape how they think about doing and teaching mathematics (Ball, 1988; Rodríguez & Kitchen, 2005). Long before preservice teachers step foot into their teacher education program, their …

Evaluating The Efficacy Of Land Snail Survey Techniques In Hawaii: Implications For Conservation Throughout The Pacific, Torsten Durkan, Norine Yeung, Wallace Meyer, Kenneth Hayes, Robert Cowie

Department of Biology Faculty Publications

Terrestrial micromolluscs (snails with an adult maximum shell dimension <5 mm) constitute a considerable proportion of the land snail fauna of the Pacific. However, micromolluscs are often underestimated in biological surveys because of size bias. It has been argued that visual searches are preferable on Pacific islands because: (1) size biases are limited based on the understanding that most native Pacific island land snails are very small, and (2) amount of labor is less than other methods such as soil surveys and adequate for inventory purposes (though not for abundance assessments). To test whether visual surveys and soil surveys were accurately recording all taxa, land snail inventories were completed in three forest reserves (5 sampling sites in each) on the island of Oahu, Hawaii. Visual surveys involved 30-min visual search in a 10 m2 site; soil surveys involved sieving leaf litter and topsoil from four 0.3 m2 quadrats and extracting snails with the aid of a microscope. The data indicate a size and microhabitat bias associated with both techniques. Visual surveys consistently collected large arboreal and litter-dwelling species but missed a significant portion of micromolluscs, while soil surveys collected micromolluscs but missed larger snails. Because of such biases, employing both methods is critical for collecting all taxa at a survey location. As such, we recommend that future land snail surveys on Pacific Islands incorporate both survey techniques. Obtaining a complete inventory is critical if we are to understand species distributions and patterns of diversity and make well-informed conservation recommendations.

Correspondence And Covariation: Quantities Changing Together, Caro C. Williams-Pierce

Mathematics and Statistics Faculty Scholarship

Exponential functions are important topic in school algebra and in higher mathematics, but research on students’ thinking suggests that understanding exponential growth remains an instructional challenge. This paper reports the results of a small-scale teaching experiment with students who explored exponential functions in the context of two continuously covarying quantities, height and time. We present two major conceptual paths that occurred in the development of an understanding of exponential growth, the covariation view and the correspondence view, and discuss the influence of each perspective on the growth of students’ understanding.

Educating Highly‐Qualified Science Teachers, Elizabeth Lewis, Aaron A. Musson, Jia Lu

Discipline-Based Education Research Group Speaker Series

Understanding what makes a highly‐qualified science teacher requires careful research on teacher education programs. Existing research pertaining to secondary science preservice teachers (PSTs) is limited in the areas of: (a) mastery of subject matter knowledge; (b) evolving teaching selfefficacy, and (c) inquiry‐based enacted curricular practices. We studied each issue over the course of an intensive, 14‐month, graduate teacher certification program for practicing scientists and recent science graduates. First, we asked if there was a relationship between amount of content area undergraduate coursework and performance (GPA in core content courses) and found an expected, yet preliminary, connection between higher undergraduate GPA …
