Health Alert: Underreported Medical Errors, Anna H. Gibson

Student Scholarship

Patient medical errors cause thousands of individual injuries and deaths each year. Avoidable medical errors occur every day, thus creating serious concern as to the safety, ethical and legal implications in healthcare delivery. A literature review of scholarly work indicates medical errors are underreported both at the institutional level and on the individual level. This paper attempts to explain why medical errors are underreported. It considers reporting practices from other industries that are applicable to the medical industry, the importance of reporting medical errors along with those incidents that have the potential to improve patient safety and patient quality of …

The Relationship Of Social Interest And Psychopathy, Amy Ann D'Ambrosio

All-Inclusive List of Electronic Theses and Dissertations

Measures of psychopathy and the Adlerian construct of social interest have both been found to predict recidivism of convicted offenders. While the two constructs seem to identify related but opposite traits, the relationship between the traits has not been systematically examined. This study examined the relationship between social interest, lll as assessed by the Sulliman Scale of Social Interest (SSSI), and psychopathy, as assessed by the Psychopathic Personality Inventory (PPI) in order to clarify their relationship. It was hypothesized that the two constructs are inversely related. The study was also designed to address the psychometric characteristics of the two scales. …

Distributed Artificial Neural Network (Dann): Model Of Human Memory Behavior, Karen Meriweather

All-Inclusive List of Electronic Theses and Dissertations

It is believed that a distributed network system will provide a general means of understanding cognitive functions that occur in the brain. This study provides a framework for modeling human memory behavior using a Distributed Artificial Neural Network (DANN) architecture. This approach presents a different method for modeling cognitive functions using peer-to-peer computing. The computers on the network represents different memory stores, and by using Hopfield Neural Network Techniques, along with the software application Joone, the final product is a DANN system that exhibits human memory behavior and the ability to associate input vectors from the Fisher's Iris Classification output …

A Swarm Intelligence Based Approach To The Mine Detection Problem, Vignesh Munirajan

Theses

This research focuses on the application of swarm intelligence to the problem of mine detection. Swarm Intelligence concepts have captivated the interests of researchers mainly in collective robotics, optimization problems (traveling salesman problem (TSP), quadratic assignment problem, graph coloring etc.), and communication networks (routing) etc [1]. In the mine detection problem we are faced with sub problems such as searching for the mines over the minefield, defusing them effectively, and assuring that the field is clear of mines within the least possible time. In the problem, we assume that the mines can be diffused by the collective action of the …

Remembering The Future: Utopia, Empire And Harmony In 21st Century International Theory, William A. Callahan

Research Collection School of Social Sciences

Using a comparative approach to international relations theory, this article examines how ancient ideas are being recycled to describe world order in the 21st century. In particular, it provides a thick description of three models of utopia in global politics - Great Harmony and Harmony-with-difference from China, and Empire from Hardt and Negri. Using an unexplored set of Chinese-language texts, the article first excavates how Communist Party intellectuals in China have been writing about the ancient Confucian ideal of Great Harmony as a way of promoting the Peoples Republic of Chinas role as a Great Power in the 21st century. …

The Political Economy Of Polarized Pluralism, Salvatore Babones, Riccardo Pelizzo

Research Collection School of Social Sciences

It is difficult to overestimate the importance of Sartori’s party system typology at least because, as Peter Mair recently pointed out, “there has been very little new thinking on how to classify systems since the seminal work of Sartori” (Mair, forthcoming). The first important party system taxonomy was proposed by Duverger in his Political Parties (1951). Duverger in this classic study identified three types of party systems: the one party system, the two party system and the multi-party system. By the early 1960s Sartori had become quite unhappy with this typology (Sartori, 1982). Sartori thought that both the one-party and …

Neglected Taxonomy Of Rare Desert Fishes: Congruent Evidence For Two Species Of Leatherside Chub, Jerald B. Johnson, Thomas E. Dowling, Mark C. Belk

Faculty Publications

Conservation biologists rely heavily on taxonomy to set the scope for biological monitoring and recovery planning of rare or threatened species. Yet, taxonomic boundaries are seldom evaluated as falsifiable hypotheses that can be statistically tested. Here, we examine species boundaries in leatherside chub (Teleostei, Cyprinidae), an imperiled desert fish native to the Bonneville Basin and upper Snake River drainages of western North America. Recent molecular data hint that this fish could be composed of two distinct taxa that are geographically separated into northern and southern species. To formally test this hypothesis, we evaluated leatherside chub using several different categories of …

Toward The Design Of Mr Agents For Imaging Β-Cell Function, Mark Woods, Shanrong Zhang, A. Dean Sherry

Chemistry Faculty Publications and Presentations

The chemistry of Gd3+-based MRI agents has advanced considerably during the past decade toward agents with higher relaxivity and agents that respond to physiology and / or metabolism. This review describes various approaches that have been taken toward the development of responsive contrast agents and discusses the importance of fast water exchange for advancement of targeted Gd3+-based agents with higher sensitivity. The recent discovery of Eu3+ complexes having extraordinarily slow water exchange has opened a new avenue in contrast agent design based upon the chemical exchange saturation transfer (CEST) mechanism. These new paramagnetic complexes called PARACEST agents offer new possibilities …

Mössbauer Spectral Study Of The Magnetocaloric Femnp₁₋ₓasₓ Compounds, Raphäel P. Hermann, Ojied Tegus, Ekkehard H. Brück, K. H. J. Buschow, Frank R. De Boer, Gary J. Long, Fernande Grandjean

Chemistry Faculty Research & Creative Works

The magnetic phase transitions in the FeMnP_1-xAs_x compounds with x= 0.25, 0.35, 0.45, 0.50, and 0.55, have been studied by iron-57 Mössbauer spectroscopy. The ferromagnetic and antiferromagnetic spectra have been analyzed with a model that takes into account the random distribution of the P and As near-neighbor anions of a given iron site. This distribution is a binomial distribution of the contributions to the spectra of each iron with n As near neighbors. A magnetostriction model has been used to characterize the temperature induced paramagnetic to ferromagnetic first-order phase transition and order parameters, η_F=2.6, 2.3, …

Analytically Calibrated Box-Cox Percentile Limits For Duration And Event-Time Models, Zhenlin Yang, Albert K.C. Tsui

Research Collection School Of Economics

This paper proposes a unified approach to constructing confidence limits for a future percentile duration or event-time. The construction is based on an analytical calibration of the Box-Cox-type “plug-in” percentile limits (PL). The performance of the calibrated Box-Cox PL is investigated using Monte Carlo experiments. Comparisons are made with PLs that are specifically designed for a particular distribution such as Weibull and lognormal. Excellent performances of the calibrated Box-Cox PL are observed. Simulation based on other popular duration models such as gamma and inverse Gaussian reveal that the proposed PL is robust against distributional assumptions and that it performs much …

Ab Initio Calculation Of Electronic And Optical Properties Of Beryllium Chalcogenides (Bes, Bese, And Bete) Under The Effect Of Pressure, Aisha Ali Saif Bannan Al-Kaabi

Theses

There are several methods for materials simulation. Ab initio or first principles methods are used to solve the quantum mechanical equation which govern the behavior of a system. Ab initio calculation of the optical and electronic properties of solids is fundamental in solid state physics. APW+lo is used to examine different properties of BeS, BeSe and BeTe. Beryllium compounds show different features in structure under different pressures, and they also show a phase transition from Zinc blende to Hexagonal transitions in II-VI semiconductors. Little is known about the ground state properties of Beryllium Chalcogenides. The aim of this work is …

U-Commerce: Emerging Trends And Research Issues, H. Galanxhi-Janaqi, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

Ubiquitous commerce or u-commerce is the combination of traditional e-commerce and wireless, television, voice and silent commerce. U-commerce implies ubiquity, universality, uniqueness and unison. It is not a replacement for other types of commerce, but an extension of them. While bringing many benefits, there are challenges and impediments to overcome. Research is needed to assess the value of u-commerce and to address its related issues and challenges. Questions that need to be addressed are: What is the value of u-commerce? What are the ways to maximize the benefits and value of u-commerce? Is it the right technology and what directions …

Method For Identifying Individuals, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

A method and system for identifying a subject comprises obtaining a digitised recording of an electrocardiogram measurement of the subject to be identified, the digitised recording being a cyclic waveform having a peak amplitude. The digitised recording is normalised to reduce variations due to physiological effects, and the normalised recording is processed to determine a feature vector in the frequency domain. The distance between the determined feature vector and a predetermined feature vector is measured to identify the subject.

College of Population Health Faculty Papers

The purpose of this study was to review economic considerations related to establishing a diagnosis of Crohn's disease, and to compare the costs of a diagnostic algorithm incorporating wireless capsule endoscopy (WCE) with the current algorithm for diagnosing Crohn's disease suspected in the small bowel. Published literature, clinical trial data on WCE in comparison to other diagnostic tools, and input from clinical experts were used as data sources for (1) identifying contributors to the costs of diagnosing Crohn's disease; (2) exploring where WCE should be placed within the diagnostic algorithm for Crohn's; and (3) constructing decision tree models with sensitivity …

The Defined Contribution Paradigm, Edward A. Zelinsky

Articles

Pension cognoscenti have frequently remarked on the stagnation of defined benefit pensions and the concomitant rise of defined contribution plans. I suggest that, over the last generation, something even more fundamental has occurred, something that can justly be called a paradigm shift. Americans today primarily conceive of and implement retirement savings in the form of individual accounts. Such accounts have become primary instruments of public policy, not just for retirement savings, but increasingly for health care and education as well.

Atoms, Complexes, And Demonstration: Posterior Analytics 96b15-25, Owen Goldin

Philosophy Faculty Research and Publications

There is agreement neither concerning the point that is being made in Posterior analytics 96b15-25 nor the issue Aristotle intends to address. There are two major lines of interpretation of this passage. According to one, sketched by Themistius and developed by Philoponus and Eustratius, Aristotle is primarily concerned with determining the definitions of the infimae species that fall under a certain genus. They understand Aristotle as arguing that this requires collating definitional predictions, seeing which are common to which species. Pacius, on the other hand, takes Aristotle to be saying that a genus is studied scientifically through first determining the …

Corrective Justice, Equal Opportunity, And The Legacy Of Slavery And Jim Crow, David B. Lyons

Faculty Scholarship

Chattel slavery was a brutally cruel, repressive, and exploitative system of racial subjugation. When it was abolished, the former slaveholders owed the freedmen compensation for the terrible wrongs of enslavement. Ex-slaves sought reparations, especially in the form of land, but few received any sort of recompense. The wrongs they suffered were never repaired.

No one alive today can be held accountable for the wrongs of chattel slavery, and those who might now be called upon to pay reparations were not even born until many decades after slavery ended. For some scholars, the lack of accountable parties makes current reparations claims …

Effects Of Variable Contact Load On Fretting Fatigue Behavior Of Shot-Peened And Un-Peened Titanium Alloy, Chia-Hawa Lee

Theses and Dissertations

Fretting fatigue occurs between two components in contact under relative motion and reduces fatigue life when compared with plain fatigue. Shot-peening, on the other hand, is the most commonly used cold working process to improve material fatigue resistance in aeronautical industries. Nearly all work accomplished to date has assumed a constant contact load while investigating fretting fatigue. The primary goal of this study was to explore fretting fatigue behavior under constant and variable contact load configurations using both shot-peened and un-peened specimens made up of Ti-6Al-4V alloy. Contact loads were applied with four different frequencies. Applied axial loads were also …

Consistency Results For The Roc Curves Of Fused Classifiers, Kristopher S. Bjerkaas

Theses and Dissertations

The U.S. Air Force is researching the fusion of multiple classifiers. Given a finite collection of classifiers to be fused, one seeks a new classifier with improved performance. An established performance quantifier is the Receiver Operating Characteristic (ROC) curve, which allows one to view the probability of detection versus the probability of false alarm in one graph. Previous research shows that one does not have to perform tests to determine the ROC curve of this new fused classifier. If the ROC curve for each individual classifier has been determined, then formulas for the ROC curve of the fused classifier exist …

Design And Model Verification Of An Infrared Chromotomographic Imaging System, Daniel A. Lemaster

Theses and Dissertations

A prism chromotomographic hyperspectral imaging sensor is being developed to aid in the study of bomb phenomenology. Reliable chromotomographic reconstruction depends on accurate knowledge of the sensor specific point spread function over all wavelengths of interest. The purpose of this research is to generate the required point spread functions using wave optics techniques and a phase screen model of system aberrations. Phase screens are generated using the Richardson-Lucy algorithm for extracting point spread functions and Gerchberg-Saxton algorithm for phase retrieval. These phase screens are verified by comparing the modeled results of a blackbody source with measurements made using a chromotomographic …

Self‐Consistent Diffusive Lifetimes Of Weibel Magnetic Fields In Gamma‐Ray Bursts, C. H. Jaroschek, H. Lesch, R. A. Treumann

Dartmouth Scholarship

Weibel filamentation in relativistic plasma shell collisions has been demonstrated as an efficient and fast mechanism for the generation of near-equipartition magnetic fields in self-consistent particle-in-cell (PIC) simulations. In generic γ-ray burst (GRB) models with kinetically dominated plasma outflow, sufficient strength and lifetime of magnetic fields are essential to validate synchrotron emission as the source of radiative outbursts. In this article we report on self-consistent PIC simulations of pair-plasma shell collisions in the highly relativistic regime with particle ensembles up to 5 × 10⁸. Energy dependence of magnetic field generation in the Weibel process is discussed, and for …

The Meyer-Neldel Rule For Diodes In Forward Bias, Ralf Widenhorn, Michael Fitzgibbons, Erik Bodegom

Physics Faculty Publications and Presentations

We analyzed the temperature dependence of the forward current of a silicon diode. Instead of representing the data in the ordinarily used current versus voltage graph, the currents are plotted for different voltages as a function of the inverse temperature. The constant voltage curves can be fitted linearly and the extrapolations of the fits seem to merge to one common focal point. Hence, we demonstrate that a real diode follows the Meyer-Neldel rule (MNR). It is shown that the MNR is due to a shift of the current from ideal-diode to high-injection-diode behavior. We will argue that the merging of …
