Learning Disabilities And Delinquent Behaviors Among Adolescents: A Comparison Of Those With And Without Comorbidity, Mary K. Evans, Samantha S. Clinkinbeard, Peter Simi

Criminology and Criminal Justice Faculty Publications

Research is inconclusive on whether adolescents with learning disabilities (LD) engage in more delinquency than adolescents without such deficits. Mixed results may result from a failure to account for the effects of co-occurring disabilities. Using the National Longitudinal Study of Adolescent Health, this study examines delinquency among adolescents without disabilities to youth with LD, Attention Disorder Symptoms (ADS), and comorbid LD/ADS. Results indicate no significant differences in property offenses, or alcohol, tobacco, and marijuana use; however, youth with LD reported significantly more violence than non-disabled youth. Findings illustrate the heterogeneous effects various disabilities have on delinquent behavior. Future research and …

The Value Of Problem Posing In Developing Creatively Gifted Mathematicians, Eric L. Mann

Faculty Presentations

The task of problem posing is often overlooked as a means to develop creatively gifted mathematicians. Silver (1997) suggested that problem posing was an instructional tactic used worldwide to develop creativity in mathematicians. More specifically, Silver advocated that deliberate instructional tactics had to be employed to precipitate creative solutions. Problem posing is often correlated with the aesthetic nature of mathematics.

In this cutting-edge session, participants’ objective is to learn about the value of problem posing through a brief presentation and have an opportunity to generate their own mathematical problem solving tasks given a mathematical concept. The intent is to encourage …

Characterization And Modeling Of Nonlinear Dark Current In Digital Imagers, Justin Charles Dunlap

Dissertations and Theses

Dark current is an unwanted source of noise in images produced by digital imagers, the de facto standard of imaging. The two most common types of digital imager architectures, Charged-Coupled Devices (CCDs) and Complementary Metal-Oxide-Semiconductor (CMOS), are both prone to this noise source. To accurately reflect the information from light signals this noise must be removed. This practice is especially vital for scientific purposes such as in astronomical observations.

Presented in this dissertation are characterizations of dark current sources that present complications to the traditional methods of correction. In particular, it is observed that pixels in both CCDs and CMOS …

The purpose of this research study is to describe and analyze the self-reported experiences of exemplary high school mathematics teachers who underwent personal and professional transformations in order to develop and use a standards-based, constructivist (SBC) teaching paradigm in their classrooms. These teachers were all past recipients of the Presidential Award for Excellence in Mathematics and Science Teaching (PAEMST), an award that required them to demonstrate that their mathematics instruction was rigorous in the manner described by the NCTM standards.

The following research questions are addressed: (a) What are the paths SBC secondary mathematics teachers who received the PAEMST pursued …

Modulation Of The Cardiac Calcium Release Channel By Homocysteine Thiolactone, Laura Jean Owen

Dissertations and Theses

Elevated levels in blood serum (≥10μmol/L) of the amino acid homocysteine is strongly correlated with the incidence of heart failure (HF). We present evidence that the cyclic thioester, homocysteine thiolactone (HTL), a metabolic product of homocysteine, irreversibly modifies proteins that regulate the contractile process in cardiac muscle. Two proteins found in the sarcoplasmic reticulum (SR), the Ca²⁺ pump (SERCA2), and the ryanodine receptor (RyR2), are responsible for controlling the cytosolic Ca²⁺ concentration and hence the contractile state of the heart. While both improper Ca²⁺ handling and elevated homocysteine levels have been considered bio-markers in HF, a direct …

Connecting Undergraduate Science Education With The Needs Of Today's Graduates, Viviane Callier, Richard H. Singiser, Nathan L. Vanderford

Markey Cancer Center Faculty Publications

Undergraduate science programs are not providing graduates with the knowledgebase and skills they need to be successful on today’s job market. Curricular changes relevant to today’s marketplace and more opportunities for internships and work experience during students’ secondary education would facilitate a smoother transition to the working world and help employers find graduates that possess both the hard and soft skills needed in the workplace. In this article, we discuss these issues and offer solutions that would generate more marketplace-ready undergraduates.

Small Quantum Dots Conjugated To Nanobodies As Immunofluorescence Probes For Nanometric Microscopy, Yong Wang, En Cai, Tobias Rosenkranz, Pinghua Ge, Kai Wen Teng, Sung Jun Lim, Andrew M. Smith, Hee Jung Chung, Frederick Sachs, William N. Green, Philip Gottlieb, Paul R. Selvin

Physics Faculty Publications and Presentations

Immunofluorescence, a powerful technique to detect specific targets using fluorescently labeled antibodies, has been widely used in both scientific research and clinical diagnostics. The probes should be made with small antibodies and high brightness. We conjugated GFP binding protein (GBP) nanobodies, small single-chain antibodies from llamas, with new ∼7 nm quantum dots. These provide simple and versatile immunofluorescence nanoprobes with nanometer accuracy and resolution. Using the new probes we tracked the walking of individual kinesin motors and measured their 8 nm step sizes; we tracked Piezo1 channels, which are eukaryotic mechanosensitive channels; we also tracked AMPA receptors on living neurons. …

The Power Of Principled Bayesian Methods In The Study Of Stellar Evolution, Ted Von Hippel, David Van Dyk, David Stenning, Elliot Robinson, Elizabeth Jeffery, Nathan Stein, William Jefferys, Erin M. O'Malley

Publications

It takes years of effort employing the best telescopes and in- struments to obtain high-quality stellar photometry, astrometry, and spectroscopy. Stellar evolution models contain the experience of life- times of theoretical calculations and testing. Yet most astronomers fit these valuable models to these precious datasets by eye. We show that a principled Bayesian approach to fitting models to stellar data yields substantially more information over a range of stellar astrophysics. We highlight advances in determining the ages of star clusters, mass ratios of binary stars, limitations in the accuracy of stellar models, post-main-sequence mass loss, and the ages of individual …

Modification Of A Single-Molecule Afm Probe With Highly Defined Surface Functionality, Fei Long, Bin Cao, Ashok Khanal, Shiyue Fang, Reza Shahbazian-Yassar

Michigan Tech Publications

Single-molecule force spectroscopy with an atomic force microscope has been widely used to study inter- and intramolecular interactions. To obtain data consistent with single molecular events, a well-defined method is critical to limit the number of molecules at the apex of an AFM probe to one or to a few. In this paper, we demonstrate an easy method for single-molecule probe modification by using the Cu-catalyzed alkyne–azide cycloaddition reaction. Excess terminal alkynes were covalently attached to the probe, and a bi-functional molecule containing an azide at one end and a carboxylic acid at the other was dissolved in the reaction …

Personalized Evaluation Of Biomarker Value: A Cost-Benefit Perspective, Ying Huang, Eric Laber

UW Biostatistics Working Paper Series

For a patient who is facing a treatment decision, the added value of information provided by a biomarker depends on the individual patient’s expected response to treatment with and without the biomarker, as well as his/her tolerance of disease and treatment harm. However, individualized estimators of the value of a biomarker are lacking. We propose a new graphical tool named the subject-specific expected benefit curve for quantifying the personalized value of a biomarker in aiding a treatment decision. We develop semiparametric estimators for two general settings: i) when biomarker data are available from a randomized trial; and ii) when biomarker …

Association Of Weekly Suicide Rates With Temperature Anomalies In Two Different Climate Types, Paul Grady Dixon Ph.D., Mark Sinyor, Ayal Schaffer, Anthony Levitt, Christa R. Haney, Kelsey N. Ellis, Scott C. Sheridan

Geosciences Faculty Publications

Annual suicide deaths outnumber the total deaths from homicide and war combined. Suicide is a complex behavioral endpoint, and a simple cause-and-effect model seems highly unlikely, but relationships with weather could yield important insight into the biopsychosocial mechanisms involved in suicide deaths. This study has been designed to test for a relationship between air temperature and suicide frequency that is consistent enough to offer some predictive abilities. Weekly suicide death totals and anomalies from Toronto, Ontario, Canada (1986-2009) and Jackson, Mississippi, USA (1980-2006) are analyzed for relationships by using temperature anomaly data and a distributed lag nonlinear model. For both …

Task-Based Robotic Grasp Planning, Yun Lin

USF Tampa Graduate Theses and Dissertations

Grasp should be selected intelligently to fulfill different stability properties and manipulative requirements. Currently, most grasping approaches consider only pick-and-place tasks without any physical interaction with other objects or the environment, which are common in an industry setting with limited uncertainty. When robots move to our daily-living environment and perform a broad range of tasks in an unstructured environment, all sorts of physical interactions will occur, which will result in random physical interactive wrenches: forces and torques on the tool.

In addition, for a tool to perform a required task, certain motions need to occur. We call it "functional tool …

Investigations Of Potential Microbial Methanogenic And Carbon Monoxide Utilization Pathways In Ultra-Basic Reducing Springs Associated With Present-Day Continental Serpentinization: The Tablelands, Nl, Can, P. L. Morrill, W. J. Brazelton, L. Kohl, A. Rietze, S. M. Miles, H. Kavanagh, M. O. Schrenk, S. E. Ziegler, Susan Q. Lang

Faculty Publications

Ultra-basic reducing springs at continental sites of serpentinization act as portals into the biogeochemistry of a subsurface environment with H2 and CH4 present. Very little, however, is known about the carbon substrate utilization, energy sources, and metabolic pathways of the microorganisms that live in this ultra-basic environment. The potential for microbial methanogenesis with bicarbonate, formate, acetate, and propionate precursors and carbon monoxide (CO) utilization pathways were tested in laboratory experiments by adding substrates to water and sediment from the Tablelands, NL, CAD, a site of present-day continental serpentinization. Microbial methanogenesis was not observed after bicarbonate, formate, acetate, or propionate addition. …
