An Extended Hierarchical Task Analysis For Error Prediction In Medical Devices, Phillip H. Chung, Jiajie Zhang, Todd R. Johnson, Vimla L. Patel

Faculty, Staff and Student Publications

This paper introduces an extended hierarchical task analysis (HTA) methodology devised to evaluate and compare user interfaces on volumetric infusion pumps. The pumps were studied along the dimensions of overall usability and propensity for generating human error. With HTA as our framework, we analyzed six pumps on a variety of common tasks using Norman’s Action theory. The introduced method of evaluation divides the problem space between the external world of the device interface and the user’s internal cognitive world, allowing for predictions of potential user errors at the human-device level. In this paper, one detailed analysis is provided as an …

Single-Cell Protein Profiling Of Wastewater Enterobacterial Communities Predicts Disinfection Efficiency, Gomathinayagam Ponniah, Han Chen, Ronda Michielutti, Nancy Salonen, Paul H. Blum

School of Biological Sciences: Faculty Publications

The efficiency of enterobacterial disinfection is dependent largely on enterobacterial community physiology. However, the relationship between enterobacterial community physiology and wastewater processing is unclear. The purpose of this study was to investigate this relationship. The influence of wastewater treatment processes on enterobacterial community physiology was examined at the single-cell level by using cultureindependent methods. Intracellular concentrations of two conserved proteins, the growth-related protein Fis and the stationary-phase protein Dps, were analyzed by epifluoresence microscopy of uncultivated cells by using enterobacterial group-specific polyclonal fluorochrome-coupled antibodies. Enterobacterial single-cell community protein profiles were distinct for different types of biological treatment. The differences were …

The Case For Registering Patents And The Law And Economics Of Present Patent-Obtaining Rules, F. Scott Kieff

GW Law Faculty Publications & Other Works

The legal rules for determining whether an inventor is entitled to a patent are presently enforced in the first instance by the Patent Office through ex parte examination of patent applications. Critics of various aspects of the patent system suggest that these rules should be ratcheted up in some way, subjecting patents to more scrutiny during Patent Office examination. Departing from existing literature, this paper offers a hypothetical model system under which patent applications are merely registered, not examined, to show how hard look approaches like examination increase social costs over soft look approaches like registration. The paper presents a …

Zelman's Future: Vouchers, Sectarian Providers, And The Next Round Of Constitutional Battles, Ira C. Lupu, Robert W. Tuttle

GW Law Faculty Publications & Other Works

This piece focuses on the Supreme Court's recent decision in Zelman v. Simmons-Harris, the Cleveland school voucher case, and the constitutional questions that have already begun to appear in its aftermath. After describing the constitutional crossroads at which the Zelman Court found itself, we offer a close reading of the Zelman opinions, paying special attention to the normative vision of church-state relations that each presupposes, the values that the Court failed to explore, and practical questions about the range of school settings to which Zelman might ultimately be applied. The piece then explores the legal and constitutional future of the …

Use Of Ground-Based Canopy Reflectance To Determine Radiation Capture, Nitrogen And Water Status, And Final Yield In Wheat, Glen L. Ritchie

Publications

Ground-based spectral imaging devices offer an important supplement to satellite imagery. Hand-held, ground-based sensors allow rapid, inexpensive measurements that are not affected by the earth’s atmosphere. They also provide a basis for high altitude spectral indices. We quantified the spectral reflectance characteristics of hard red spring wheat (Triticum aestivum cv. Westbred 936) in research plots subjected to either nitrogen or water stress in a two year study. Both types of stress reduced ground cover, which was evaluated by digital photography and compared with ten spectral reflectance indices. On plots with a similar soil background, simple indices such as the normalized …

Winter Ecology Of Kokanee: Implications For Salmon Management, G. B. Steinhart, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

We sampled various limnological parameters and measured growth and diet of age-0 kokanee Oncorhynchus nerka (lacustrine sockeye salmon) during two winters in a high-mountain lake of the Sawtooth Valley, Idaho. Although winter has been recognized as an important period for many warmwater fishes and for stream-dwelling salmonids, winter limitations have only recently been studied for coolwater and coldwater species. Ice and snow cover in winter limited light penetration. As a result, chlorophyll-a and zooplankton density were lower in ice-covered periods than during ice-free periods. The weight of stomach contents was often below a maintenance ration, yet the incidence of empty …

Comparison Of Classical And Charge Storage Methods For Determining Conductivity Of Thin Film Insulators, Prasanna Swaminathan, A. R. Frederickson, John R. Dennison, Alec Sim, J. Brunson, Eric Crapo

All Physics Faculty Publications

Conductivity of insulating materials is a key parameter to determine how accumulated charge will distribute across the spacecraft and how rapidly charge imbalance will dissipate. Classical ASTM and IEC methods to measure thin film insulator conductivity apply a constant voltage to two electrodes around the sample and measure the resulting current for tens of minutes. However, conductivity is more appropriately measured for spacecraft charging applications as the "decay" of charge deposited on the surface of an insulator. Charge decay methods expose one side of the insulator in vacuum to sequences of charged particles, light, and plasma, with a metal electrode …

Video Categorization Using Semantics And Semiotics, Zeeshan Rasheed

Retrospective Theses and Dissertations

There is a great need to automatically segment, categorize, and annotate video data, and to develop efficient tools for browsing and searching. We believe that the categorization of videos can be achieved by exploring the concepts and meanings of the videos. This task requires bridging the gap between low-level content and high-level concepts (or semantics). Once a relationship is established between the low-level computable features of the video and its semantics, the user would be able to navigate through videos through the use of concepts and ideas (for example, a user could extract only those scenes in an action film …

Growth Mechanism And Some Properties Of Cd_{1-X}Mn_X Se Semimagnetic Semiconductor Thin Films, V. S. Karande, S. H. Mane, Vithal Bhivaba Pujari, L. P. Deshmukh

Turkish Journal of Physics

(Cd, Mn) Se dilute semiconductor or semimagnetic semiconductors have recently became the focus of intense research due to their interesting combination of magnetic and semiconducting properties, and are employed in a variety of devices including solar cells, gas sensors etc. A series of thin films of this material, Cd_{1 - x}Mn_xSe (0 \le x \le 0.5), were therefore synthesized onto precleaned amorphous glass substrates using a solution growth technique. The sources of cadmium (Cd^{2+}) and manganese (Mn^{2+}) were aqueous solutions of cadmium sulphate and manganese sulphate, and selenium (Se^{2-}) was extracted from a reflux of sodium selenosulphite. The different deposition …

The Spatially Averaged Electric Field In The Near Field And Far Field Of A Circular Aperture, Charles Daly, Todd Nuteson, Navalgund Rao

Articles

This paper presents a theoretical and numerical investigation of the spatially averaged electric field in the beam of a circular aperture. The investigation leads to closed-form analytical expressions, based on scalar diffraction theory, which describe the spatially averaged electric field in the Fresnel region of a circular aperture excited by a spatially uniform, harmonic plane wave. The expressions ultimately permit rapid, practical, and efficient prediction of certain routine electromagnetic measurements. Because the expressions are valid in the Fresnel region, they are also valid in the near field, the far field, and the Fraunhofer region of a circular aperture. In fact, …

Preservice Elementary School Teachers’ Understandings Of Theory Based Science Education, Edmund A. Marek, Timothy A. Laubach, Jon Pedersen

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Undergirding the science education program examined in this study is a theoretical foundation based upon four cornerstones that reflect scientific inquiry. These four cornerstones are best represented by four key questions: (a) What is science; (b) What are the goals or standards for elementary school science education; (c) What theory describes how elementary school children construct knowledge; and (d) What teaching approach represents the discipline of science, achieves the goals of elementary school science education and accommodates to how children construct knowledge? The learning cycle (Barman & Kotar, 1989; Bentley, Ebert,& Ebert II, 2000; Lawson, Abraham, & Renner, 1989; Marek …

Constructivism: Defense Or A Continual Critical Appraisal – A Response To Gil-Pérez Et Al., Mansoor Niaz, Fouad Abd-El-Khalick, Alicia Benarroch, Liberato Cardellini, Carlos E. Laburu, NicoláS Marín, Luis A. Montes, Robert Nola, Yuri Orlik, Lawrence C. Scharmann, Chin-Chung Tsai, Georgios Tsaparlis

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Abstract. This commentary is a critical appraisal of Gil-Pérez et al.’s (2002) conceptualization of constructivism. It is argued that the following aspects of their presentation are problematic: (a) Although the role of controversy is recognized, the authors implicitly subscribe to a Kuhnian perspective of ‘normal’ science; (b) Authors fail to recognize the importance of von Glasersfeld’s contribution to the understanding of constructivism in science education; (c) The fact that it is not possible to implement a constructivist pedagogy without a constructivist epistemology has been ignored; and (d) Failure to recognize that the metaphor of the ‘student as a developing scientist’ …

Growth And Survivorship Of Meandrina Meandrites And Montastrea Cavernosa Transplants To An Artificial Reef Environment, And The Effectiveness Of Plugging Core Holes In Transplant Donor Colonies, Elizabeth Glynn Fahy

HCNSO Student Theses and Dissertations

The growth and survivorship of two species of scleractinian coral transplants, Meandrina meandrites and Montastrea cavernosa, were investigated. Identically sized replicate transplants were obtained from the second reef, off Dania Beach, using a hydraulic drill fitted with a 4” core barrel. The transplants were fixed to Reef Ball™ substrates using an adhesive marine epoxy. Drill holes in the donor corals (core holes) were filled with concrete plugs to prevent the detrimental effects of bioeroders. Control corals, of comparable size to both the donor colonies and the transplant corals, were selected for comparison. The transplant corals, donor corals, and controls …

An Additive Schwarz Preconditioner For The Spectral Element Ocean Model Formulation Of The Shallow Water Equations, Craig C. Douglas, Gundolf Haase, Mohamed Iskandarani

Computer Science Faculty Publications

We discretize the shallow water equations with an Adams-Bashford scheme combined with the Crank-Nicholson scheme for the time derivatives and spectral elements for the discretization in space. The resulting coupled system of equations will be reduced to a Schur complement system with a special structure of the Schur complement. This system can be solved with a preconditioned conjugate gradients, where the matrix-vector product is only implicitly given. We derive an overlapping block preconditioner based on additive Schwarz methods for preconditioning the reduced system.
