Application Essays As An Effective Tool For Assessing Instruction In The Basic Communication Course: A Follow-Up Study, Joseph P. Mazer, Cheri J. Simonds, Stephen K. Hunt

Publications

The assessment of student learning in general education courses is of critical importance in higher education. This study examines the utility of a writing assignment (application essays) in a basic communication course as an effective assessment tool. The authors conducted a content analysis of student portfolios to determine the extent to which application essays provide evidence of student learning in the basic course. The present study extends the findings from recent assessment efforts (Jones, Simonds, & Hunt, 2005) to explore types of mass media events students address in application essays and assess the revisions made to the assignment based on …

Tracking Plagiarism Electronically: First-Year Students’ Perceptions Of Academic Dishonesty And Reports Of Cheating Behaviour In The Basic Communication Course, Joseph P. Mazer, Stephen K. Hunt

Publications

This study explored how electronic submission of course material, intended to deter instances of plagiarism, influenced first-year students’ perceptions of academic dishonesty and reports of cheating behaviour in a large, multi-section basic communication course. Results reveal that electronic submission of course material results in first-year students being less likely to self-report engaging in cheating behaviours and heightens their appreciation and awareness of what constitutes academic dishonesty. Implications for classroom pedagogy, course management, and teacher training are discussed.

We report on follow-up observations of 20 short-duration gamma-ray bursts (GRBs; T90 <2 >s) performed in g'r'i'z' JHKs with the Gamma-Ray Burst Optical Near-Infrared Detector (GROND) between mid-2007 and the end of 2010. This is one of the most compre-hensive data sets on GRB afterglow observations of short bursts published so far. In three cases, GROND was on target within less than 10 min after the trigger, leading to the discovery of the afterglow of GRB 081226A and its faint underlying host galaxy. In addition, GROND was able to image the optical afterglow and follow the light curve evolution in five …

Protein Nano-Object Integrator (Pronoi) For Generating Atomic Style Objects For Molecular Modeling, Nicholas Smith, Brandon Campbell, Lin Li, Chuan Li, Emil Alexov

Publications

Background

With the progress of nanotechnology, one frequently has to model biological macromolecules simultaneously with nano-objects. However, the atomic structures of the nano objects are typically not available or they are solid state entities. Because of that, the researchers have to investigate such nano systems by generating models of the nano objects in a manner that the existing software be able to carry the simulations. In addition, it should allow generating composite objects with complex shape by combining basic geometrical figures and embedding biological macromolecules within the system.

Results

Here we report the Protein Nano-Object Integrator (ProNOI) which allows for …

Dynamic And Static Effects In Wetting Of Capillaries And Fibers, Taras Andrukh

All Dissertations

This research is centered on the analysis of static and dynamic effects of wetting of single capillaries and fibers. We discuss specifics of the capillary rise and drop-on-fiber techniques and develop new methods of characterization of surface energy of single fibers when its contact angle varies between zero and ninety degrees. The contact angles were evaluated and compared for different substrates. We study the dynamics of the meniscus formation inside and outside of capillaries and fibers. We develop a mathematical model of liquid uptake by capillaries and analyze the factors affecting liquid uptake. The derived fundamental equation describes the dynamics …

Induced Elastic Matrix Synthesis Within 3-Dimensional Collagen Constructs, Lavanya Venkataraman

All Dissertations

Elastin, a primary component of elastic arteries, maintains structural stability of the cyclically recoiling artery, and critically regulates vascular cell behavior. Accelerated degradation of elastic matrix, such as that seen in vascular pathologies like abdominal aortic aneurysms (AAA), can therefore severely compromise vessel homeostasis. Tissue engineering and in-situ matrix repair strategies evaluated so far are primarily limited in inducing adult vascular cells to replicate the complex elastic matrix assembly process, and restore lost matrix integrity. Previously, our lab established the elastogenic benefits of concurrent delivery of TGF-β1 and HA-oligomers (together termed elastogenic factors, EFs), within 2D cultures of rat aortic …

Fate And Reactivity Of Natural And Manufactured Nanoparticles In Soil/Water Environments, Allison Vandevoort

All Dissertations

Nanoparticles (NPs), < 100 nm in diameter, make up the smallest component of solid material. This small size often causes increased reactivity in soil/water environments, which is true for both natural NPs, such as very fine clay particles, and for manufactured nanoparticles, such as silver nanoparticles (AgNPs). As the importance of these particles is more widely recognized, and as manufactured nanoparticles, especially AgNPs, are increasing in production, it is essential to consider their effect on terrestrial and aquatic environments. The studies presented in this dissertation show that both the physicochemical characteristics of the NPs (e.g., particle size, surface coating, elemental composition), as well as soil-water interfacial chemistry (e.g., ionic strength, ligand concentration, pH), are instrumental in predicting environmental fate and reactivity.
Ligand type and concentration were especially important in NP reactivity and bioavailability. Using the hard/soft acid/base concept, the effect of phosphate ligand (hard base) on Fe/Al (hard acid) oxyhydroxide natural NPs was investigated in Chapters 2 and 3. Adding phosphate to soil NPs and reference nano-minerals (Fe-(oxyhydr)oxides and kaolinite) caused coagulation or dispersion, changing the particle size of the NPs, as well as affecting the amount of phosphate in its bioavailable (i.e., dissolved) form. A review of the literature in Chapters 1 and 3 revealed that changes in the soil conditions, and therefore, soil colloids/NPs (e.g., increasing organic …

Navigating The World Of Academia As A Mother And Contingent Faculty Member: A Narrative Inquiry, Kathryn Ledford

All Dissertations

Although women hold many professional positions, they are still held accountable to present gendered customs like parenting children. Additionally, women who work in higher education are surrounded by masculine norms. For academic women who are also mothers like the author, many obstacles confront their management of the interlocking spheres of home, work and self. An examination of these women's narratives will illuminate how women navigate the world of academia, while maintaining our roles as mothers and individual identities.
For women who are mothers of children under six years old, and who are also contingent faculty members at four-year institutions, both …

Phase Transformation In Ti-Mo-O, Herbert Boeckels

All Dissertations

The present dissertation has investigated the effect of oxygen on the ù and á phase stability in metastable Ti-Mo â titanium alloys using thermal analysis, hardness measurements, electron microscopy, and x-ray diffraction.
Single crystal x-ray diffraction has shown that oxygen atoms are located in the tetrahedral interstitial lattice sites in the rapidly cooled bcc Ti crystal structure, interfering directly with the reversible displacive formation of ù, with this transformation involving collapse of the bcc lattice along â. Subsequent thermal exposure of reversible ù, as occurring during slower cooling, heating, and aging, prompts short range diffusion and the formation of chemical …

Managing Elective And Non-Elective Case Assignments For An Operating Room Suite, Narges Hosseini

All Dissertations

The success of operating room management depends on all levels of decision making, from strategic to tactical and operational decisions. One key decision in systems with block booking is to assign sufficient amount of block time to surgeons and surgery groups. While the typical method of block assignment identifies the share of surgery groups from OR times based on average of past usage, this method does not count for the difference between cost of under and overtime. One of the goals of this research is to develop a decision framework for block assignment. This work is presented in chapter two. …

Understanding The Relative Attentional Demands Of The Dimensions Of Interface Consistency, Jeremy Mendel

All Dissertations

A consistent interface is thought to be beneficial because it allows users to draw on previous training and experience when operating a new interface. Design guidelines like the eight golden rules of interface design argue that a highly consistent interface improves system usability (Shneiderman, 1987). However, interface consistency is not monolithic; instead it is a complex, multidimensional construct. I refer to the two dimensions of interface consistency as perceptual consistency (the appearance) and conceptual consistency (the functionality) of an interface. Perceptual consistency considers aspects like interface layout and orientation; conceptual consistency considers how the system operates or responds. I sought …

Family Cancer History And Pedigrees As A Public Health Intervention For Promoting Health And Preventing Prostate Cancer In African American Men, Holisa Wharton

All Dissertations

ABSTRACT
Prostate cancer is the most common cancer diagnosed in men and the second leading cause of cancer death among men in the United States. African-American men have substantially higher prostate cancer incidence and mortality than European-American men. It is unclear whether this incidence is due to acquired DNA changes (sporadic cancer) or if germline Mendelian genetics/genomics (inherited cancer) is the source of this health disparity. To explore this cause, the focus of this dissertation paper is family health history and hereditary prostate cancer. A family history tool is the most commonly used predictive instrument for hereditary prostate cancer. The …

Synthesis And Characterization Of Nanoscale Fluorescent Polymer Films, Maryus Chyasnavichyus

Performance of the chemical sensing devices is based sensitivity to the targeted analytes and accuracy of the measurements. Of many different types of chemical sensors, fluorescence based sensing devices draw much attention as efficient yet small and straightforward devices, capable of detection of various analytes at extremely small quantities.
Polymeric materials provide support for the fluorescent materials and usually serve as a host for the chromophores, protecting them from harsh environments, and serve as a transport media for the analyte.
In the present study thin fluorescent polymer films, sensitive to the environment are synthesized and studied. Poly(glycidyl methacrylate) was used …

Photo-Thermal Processing Of Semiconductor Fibers And Thin Films, Nishant Gupta

All Dissertations

Furnace processing and rapid thermal processing (RTP) have been an integral part of several processing steps in semiconductor manufacturing. The performance of RTP techniques can be improved many times by exploiting quantum photo-effects of UV and vacuum ultraviolet (VUV) photons in thermal processing and this technique is known as rapid photo-thermal processing (RPP). As compared to furnace processing and RTP, RPP provides higher diffusion coefficient, lower stress and lower microscopic defects. In this work, a custom designed automated photo assisted processing system was built from individual parts and an incoherent light source. This photo-assisted processing system is used to anneal …

Intersecting Identities Of Female College Student Intramural Sports Officials: A Grounded Theory, April Flint

Intramural activities are conducted on virtually every college campus throughout the United States, but there is a debate as to the role of intramurals in the overall development of the student (Rothwell & Theodore, 2006). Specifically for females, not every sport is offered for participation at youth or higher levels, but intramural sports is one arena where they have the chance to learn the sport rules and referee the game. This study aims to create a base of knowledge on the experiences of female college students who work on campus as intramural sports officials. The purpose of the study is …

The Effects Of 0.2 Hz Varying Latency With 20-100 Ms Varying Amplitude On Simulator Sickness In A Helmet Mounted Display, Matthew St. Pierre

All Dissertations

The relationship between the occurrence of simulator sickness (SS) and the several characteristics of latency (i.e., added latency, amplitude of latency, and frequency of latency) in a helmet-mounted display (HMD) were explored in this study. The experience of SS while using an HMD has often been attributed to system latency. These findings are typical in research where HMDs with head trackers are used. The current study explored the effects of 200 ms added constant latency, latency varying at 0.2 Hz with a constant 100 ms amplitude, and latency varying at 0.2 Hz with a 20-100 ms varying amplitude on the …

Updated Force Model For Milling Nickel-Based Superalloys, Andrew Henderson

All Dissertations

Nickel-based superalloys are commonly used in applications which require high strength and resistance to creep and oxidation in extreme conditions. All nickel-based superalloys are considered difficult to machine; however, cast gamma-prime-strengthened nickel-based superalloys are more difficult to machine than common nickel-based superalloys. Machining comprises a significant portion of manufacturing processes and with advancements in technology and material properties, the methods and models used must be adapted in order to keep pace.
In this research, correlations are made, using fundamental principles, between measurements made with on-machine touch probes and the cutting tool's wear state, those correlations are used in an adaptive …
