Implementation of A Nurse-Driven Educational Intervention for Prompt Removal of Urinary Catheters in the Neuro ICU
Creators: name: Ouma, Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Background: Catheter-associated urinary tract infections (CAUTIs) are the most prevalent, yet preventable hospital acquired infections that are associated with adverse outcomes. CAUTIs have been linked to increased morbidity and mortality; increased healthcare cost, and extended hospital stays. Patients in the neurological intensive care units are at higher risk of acquiring CAUTIs due to their complex conditions requiring extended hospital stay and prolonged use of an indwelling urinary catheter. Purpose: The purpose of this quality improvement project was to implement a unit-wide nurse-driven educational intervention using recommended guidelines to improve best practices related to prompt removal of the indwelling urinary catheter. Methods: A quasi-experimental design was used to test the impact of nurse-driven educational intervention on practices related to prompt removal of the urinary catheter in the neuroscience intensive care unit. Records of patients admitted between August 1st 2016 and October 30th, 2016, were randomly reviewed retrospectively. Staff was educated on the importance of adherence to unit CAUTI bundle with emphasis on prompt removal practices. A 3-month post implementation chart review was conducted for comparison with pre-intervention data. Results: Mean duration of time to urinary catheter removal post order for removal (n = 54 pre-intervention, n=54 post intervention) decreased from 241.26 minutes to 104.07 minutes. Although not statistically significant, the mean rate of CAUTIs decreased from 5.8 to 1.5 per 1,000 catheter days. Catheter reinsertion rates increased from 3.1 to 4.6 percent. Conclusion: Nurse-driven educational intervention led to a decrease in time to urinary catheter removal. Based on these findings, emphasis should be placed on decreasing the duration of catheterization which is the single most important risk factor for CAUTI particularly in at risk group such as patient with neurological injuries who require vigilant monitoring to prevent CAUTIs.

description: Paradigms provide an inherent organizational structure to natural language morphology. ParaMor, our minimally supervised morphology induction algorithm, retrusses the word forms of raw text corpora back onto their paradigmatic skeletons; performing on par with state-of-the-art minimally supervised morphology induction algorithms at morphological analysis of English and German. ParaMor consists of two phases. Our algorithm first constructs sets of affixes closely mimicking the paradigms of a language. And with these structures in hand, ParaMor then annotates word forms with morpheme boundaries. To set ParaMor’s few free parameters we analyze a training corpus of Spanish. Without adjusting parameters, we induce the morphological structure of English and German. Adopting the evaluation methodology of Morpho Challenge 2007 (Kurimo et al., 2007), we compare ParaMor’s morphological analyses with Morfessor (Creutz, 2006), a modern minimally supervised morphology induction system. ParaMor consistently achieves competitive F1 measures.
A Product Brand is its Nation's Brand: A Case Study on the Promotion of Chilean Wines in the United States

Year: 2017

description: In the last 25 years, Chile opened its economy to the world, exporting different goods and services and signing trade agreements with more than 60 countries. Wine is one of the most exported products from Chile to the United States. However, despite the economic success in the relations between both countries, Chilean wines still seem to be unknown to the average American citizen. Through a competitive analysis and in-depth interviews, this study seeks to understand how Chilean wineries can make use of different integrated marketing communications (IMC) campaigns to strategically approach publics involved in the wine distribution chain, such as wholesalers, owners of restaurants, sommeliers, chefs, managers at supermarkets, specialized media outlets in wine and gastronomy, and also final consumers.

description: We introduce a dinstint approach to engineer a topologically protected surface state of a topological insulator. By covering the surface of a topological insulator, Bi2Te2Se, with a Bi monolayer film, the original surface state is completely removed and three new spin helical surface states, originating from the Bi film, emerge with different dispersion and spin polarization, through a strong electron hybridization. These new states play the role of topological surface states keeping the bulk topological nature intact. This mechanism provides a way to create various different types of topologically protected electron channels on top of a single topological insulator, possibly with tailored properties for various applications.

description: The main objective of this article is to present details of an approach that develops universal formulas to solve the Kepler problem. The equations of motion and the energy integral of the two-body problem are derived. By applying the Sundman transformation to regularize the dynamics of the problem, we can eliminate a singularity and obtain two regularized equations of motion. Using families of Battin and Stumpff functions determined from solutions of regularized differential equations, we have derived formulas that are universally applicable and free from numerical indeterminacy. This includes the expression for the radial distance, the Kepler's universal equation, the closed-form expressions for the coefficients $f$, $\dot{f}$, $g$ and $\dot{g}$, and the expressions for the orbit state variables.

description: Seit der Entdeckung der kosmischen Strahlung Anfang des 20. Jahrhunderts wurden viele Experimente entwickelt, um sie direkt oder anhand der Luftschauer zu studieren, die sie beim Eintritt in die Erdatmosphäre erzeugen. Das größte Observatorium zur Erfassung von Luftschauern ist das Pierre-Auger-Observatorium in Malargüe, Argentinien. Hier werden viele Fragen der Astro- und Teilchenphysik behandelt. Da kosmische Strahlung Energien abdeckt, die weit über denen liegen, die in künstlichen Beschleunigern erreichbar sind, stellen sie hervorragende und einzigartige Objekete dar, an denen man physikalische Eigenschaften bei höchsten Energien studieren kann. Wenn ein Luftschauer die Atmosphäre durchquert, wächst die Anzahl der in ihm enthaltenen Teilchen. Gleichzeitig nehmen ihre Energien ab. Wenn diese tief genug sind, zerfallen die Teilchen oder werden in der Atmosphäre absorbiert, was die Zahl der Teilchen wieder verringert. Dies ergibt eine Position maximaler Entwicklung $X_\mathrm{max}$. Hadronisch wechselwirkende Teilchen bringen Myonen hervor, die am Boden gemessen werden können. Diese Zahl $N_{\mu}$ zusammen mit $X_\mathrm{max}$ sind Observablen, die in Auger gemessen werden und eine aussagekräftige Antikorrelation aufweisen. In der vorliegenden Arbeit wird diese Antikorrelation studiert. Es wird ein analytisches Modell entwickelt, das diese als Funktion von Parametern wiedergibt, die die hadronische Multiplizität, den hadronischen Energieanteil und die Inelastizität der ersten Interaktion beschreiben, zusammen mit entsprechenden effektiven Parametern, die für den gesamten Schauer repräsentativ sind. Dieses Modell wird dann anhand künstlicher neuronaler Netze weiter verbessert. Hierfür werden Werte der Parameter und Observablen von Simulationen benutzt, die mit CONEX durchgeführt wurden. Das resultierende Modell hängt nicht von dem während der Simulation verwendeten Hochenergie-Wechselwirkungsmodell ab. Schließlich wird ein Modell mit reduziertem Parametersatz auf einen Datensatz von Auger angewendet. Die Verteilungen der hadronischen Multiplizität und des hadronischen Energieanteils der ersten Wechselwirkung und die der effektiven Inelastizität werden diesem Datensatz entnommen. Sie zeigen, dass die Multiplizität und der Energieanteil der ersten Wechselwirkung in aktuellen Modellen, die für Simulationen verwendet werden, im Allgemeinen zu niedrig sind.

description: Many information retrieval systems provides access to abstracts. For example Stanford University, through its FOLIO system, provides access to the INSPEC database of abstracts of the literature on physics, computer science, electrical engineering, etc. In this article this database is studied by using a trace-driven simulation. We focus on a physical index design which accommodates truncations, inverted index caching, and database scaling in a distributed shared-nothing system. All three issues are shown to have a strong effect on response time and throughput. Database scaling is explored in two ways. One way assumes an ``optimal'' configuration for a single host and then linearly scales the database by duplicating the host architecture as needed. The second way determines the optimal number of hosts given a fixed database size.
METHODS FOR COST-EFFECTIVE SYNTHESIS OF HEPARAN SULFATE POLYSACCHARIDES
Creators: name: Woody, Susan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Heparin is a highly sulfated polysaccharide that is commercially available for anticoagulation. As an animal sourced product, heparin is heterogeneous and contains polysaccharides that differ in length and sulfation patterns. In 2007, heparin sourced from porcine intestines was contaminated with over-sulfated chondroitan sulfate. Taken in conjunction with other possible pharmacological activities, there have been efforts to synthesize distinct heparan sulfate polysaccharides in a cost-effective manner, including chemoenzymatic synthesis. Some of the limitations associated with chemoenzymatic synthesis include expensive starting materials and incomplete synthesis leading to a product mixture. In an effort to overcome the first obstacle we developed two methods to efficiently synthesize the starting materials for heparan sulfate chemoenzymatic synthesis, including UDP-GlcNTFA and UDP-GlcA, from glucosamine and glucose respectively. To overcome the second obstacle, we explored possible inhibition by the chemoenzymatic co-factor PAPS. Both of these projects aim to advance the production of heparin and heparan sulfate polysaccharides.

description: Classical chaos is often characterized as exponential divergence of nearby trajectories. In many interesting cases these trajectories can be identified with geodesic curves. We define here the entropy by $S = \ln χ(x)$ with $χ(x)$ being the distance between two nearby geodesics. We derive an equation for the entropy which by transformation to a Ricatti-type equation becomes similar to the Jacobi equation. We further show that the geodesic equation for a null geodesic in a double warped space time leads to the same entropy equation. By applying a Robertson-Walker metric for a flat three-dimensional Euclidian space expanding as a function of time, we again reach the entropy equation stressing the connection between the chosen entropy measure and time. We finally turn to the Raychaudhuri equation for expansion, which also is a Ricatti equation similar to the transformed entropy equation. Those Ricatti-type equations have solutions of the same form as the Jacobi equation. The Raychaudhuri equation can be transformed to a harmonic oscillator equation, and it has been shown that the geodesic deviation equation of Jacobi is essentially equivalent to that of a harmonic oscillator. The Raychaudhuri equations are strong geometrical tools in the study of General Relativity and Cosmology. We suggest a refined entropy measure applicable in Cosmology and defined by the average deviation of the geodesics in a congruence.

description: A common and natural intuition among software testers is that test cases need to differ if a software system is to be tested properly and its quality ensured. Consequently, much research has gone into formulating distance measures for how test cases, their inputs and/or their outputs differ. However, common to these proposals is that they are data type specific and/or calculate the diversity only between pairs of test inputs, traces or outputs. We propose a new metric to measure the diversity of sets of tests: the test set diameter (TSDm). It extends our earlier, pairwise test diversity metrics based on recent advances in information theory regarding the calculation of the normalized compression distance (NCD) for multisets. An advantage is that TSDm can be applied regardless of data type and on any test-related information, not only the test inputs. A downside is the increased computational time compared to competing approaches. Our experiments on four different systems show that the test set diameter can help select test sets with higher structural and fault coverage than random selection even when only applied to test inputs. This can enable early test design and selection, prior to even having a software system to test, and complement other types of test automation and analysis. We argue that this quantification of test set diversity creates a number of opportunities to better understand software quality and provides practical ways to increase it.

description: This study assessed the knowledge and attitudes of Chinese college students studying in the United States toward HIV/AIDS, people living with HIV/AIDS, and sources of HIV-related information. The study also explored a culturally-based HIV intervention (poster) targeted at Chinese students in the US. In-depth telephone interviews were conducted with five key informants to generate ideas on message and poster design. An online survey was conducted among 95 students from a local university to examine HIV/AIDS-related knowledge and attitudes, and to determine the different effects of gain- and loss-framed message designs in different message formats (text based only, text and numerically based, and text and graphically based). Chi-square, T-test, and Pearson correlation were used to investigate the association among gender, age, relationship, knowledge on HIV/AIDS, and attitudes toward people living with HIV/AIDS. The Internet was the main source for Chinese college students in the United States searching for general health-related information. Chinese college students in the U.S. did not have comprehensive knowledge about HIV/AIDS. Gain-framed message was preferred in all message formats (text only based, text and numerically based, text and graphically based).

description: We consider implications of the microscopic dynamics of spacetime for the evolution of cosmological models. We argue that quantum geometry effects may lead to stochastic fluctuations of the gravitational constant, which is thus considered as a macroscopic effective dynamical quantity. Consistency with Riemannian geometry entails the presence of a time-dependent dark energy term in the modified field equations, which can be expressed in terms of the dynamical gravitational constant. We suggest that the late-time accelerated expansion of the Universe may be ascribed to quantum fluctuations in the geometry of spacetime rather than the vacuum energy from the matter sector.

description: Yoga and meditation have become mainstream practices in the United States, undertaken by 6 percent and 9 percent of the population, respectively, in 2007. In four articles, this master's thesis examines the practice of yoga and meditation by nontraditional populations. The first article is an overview piece on yoga and meditation, which explains what constitutes these practices, as well as who participates in them and why. The second article examines prison meditation programs in North Carolina, profiles two former inmates who benefited from meditation, and describes a meditation class at a state prison. The third article provides an overview of yoga programs for military service members and veterans, and discusses the stigma of yoga within military circles. The fourth article provides guidelines for yoga teachers on instructing service members or veterans. This thesis aims to explore yoga and meditation in-depth and show how and why these practices are reaching new audiences.

description: Hexagonal boron nitride (hBN) is a natural hyperbolic material which can also accommodate highly dispersive surface phonon-polariton modes. In this paper, we examine theoretically the mid-infrared optical properties of graphene-hBN heterostructures derived from their coupled plasmon-phonon modes. We found that the graphene plasmon couples differently with the phonons of the two Reststrahlen bands, owing to their different hyperbolicity. This also leads to distinctively different interaction between an external quantum emitter and the plasmon-phonon modes in the two bands, leading to substantial modification of its spectrum. The coupling to graphene plasmons allows for additional gate tunability in the Purcell factor, and narrow dips in its emission spectra.

Peace to Violence: Explaining the Violent Escalation of Nonviolent Demonstrations
Creators: name: Gustafson, Daniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Under what conditions do nonviolent demonstrations escalate to violence? I answer this question using a novel theory of individual preference formation in protests that begin peacefully. Rather than considering protest groups as unitary actors, I present a theory of collective action in which a group's decision is the product of a probabilistic aggregation of individual preferences. I argue that individuals involved in a nonviolent demonstration use the immediacy of their needs and the sustainability of collective action to decide whether or not to initiate violence against the state. Specifically, I hypothesize that the likelihood of violent escalation will increase when the relative food price is high, a demonstration is rural, and the event is spontaneous. An analysis of nonviolent demonstrations in Africa and Latin America largely supports my expectations.

description: The performance of distributed text document retrieval systems is strongly influenced by the organization of the inverted index. This paper compares the performance impact on query processing of various physical organizations for inverted lists. We present a new probabilistic model of the database and queries. Simulation experiments determine which variables most strongly influence response time and throughput. This leads to a set of design trade-offs over a range of hardware configurations and new parallel query processing strategies.

description: We investigate the local stability of strongly magnetized relativistic tori orbiting Kerr black holes, for the case of a purely toroidal magnetic field topology. Our approach encompasses both solving the full dispersion relation numerically and solving a simplified analytic treatment. Both approaches indicate that such tori are subject to an unstable non-axisymmetric magnetorotational mode, regardless of such background properties as the gas-to-magnetic pressure ratio and specific angular momentum distribution. We demonstrate that our modal analysis matches well with what is seen in global, three-dimensional, general relativistic magnetohydrodynamic simulations.

description: The concept of Late Veneer has been introduced by the geochemical community to explain the abundance of highly siderophile elements in the Earth's mantle and their chondritic proportions relative to each other. However, in the complex scenario of Earth accretion, involving both planetesimal bombardment and giant impacts from chondritic and differentiated projectiles, it is not obvious what the "Late Veneer" actually corresponds to. In fact, the process of differentiation of the Earth was probably intermittent and there was presumably no well-defined transition between an earlier phase where all metal sunk into the core and a later phase in which the core was a closed entity separated from the mantle. In addition, the modellers of Earth accretion have introduced the concept of "Late Accretion", which refers to the material accreted by our planet after the Moon-forming event. Characterising Late Veneer, Late Accretion and the relationship between the two is the major goal of this chapter.

description: Motivated by the energy dependent metric in gravity's rainbow, we will propose a new kind of energy dependent noncommutative geometry. It will be demonstrated that like gravity's rainbow, this new noncommutative geometry is described by an energy dependent metric. We will analyse the effect of this noncommutative deformation on the Schwarzschild black holes and Kerr black holes. We will perform our analysis by relating the commutative and this new energy dependent noncommutative metrics using an energy dependent Moyal star product. We will also analyze the thermodynamics of these new noncommutative black hole solutions. We will explicitly derive expression for the corrected entropy and temperature for these black hole solutions. It will be demonstrated that for these deformed solutions black remnants cannot form. This is because these correction increase rather than reduce the temperature of the black holes.

description: Modern technologies are generating ever-increasing amounts of data. Making use of these data requires methods that are both statistically sound and computationally efficient. Typically, the statistical and computational aspects are treated separately. In this paper, we propose an approach to entangle these two aspects in the context of regularized estimation. Applying our approach to sparse and group-sparse regression, we show that it can improve on standard pipelines both statistically and computationally.

description: Most of current machine vision systems suffer from a lack of flexibility to account for the high variability of unstructured environments. Here, as the state of the world evolves the information provided by different visual attributes changes, breaking the initial assumptions of the vision system. This paper describes a new approach for the creation of an adaptive visual system able to selectively combine information from different visual dimensions. Using a probabilistic approach and uncertainty metrics, the system is able to take appropriate decisions about the more relevant visual attributes to consider. The system is based on an intelligent agent paradigm. Each visual algorithm is implemented as an agent, which adapts its behavior according to uncertainty considerations. The proposed system aims to achieve robustness and efficiency. By combining the outputs of multiple vision modules the assumptions and constraints of each module are factored out resulting in a more robust system. Efficiency is achieved through the on-line selection and specialization of the agents. An implementation of the system for the case of human tracking showed encouraging results.

description: Thesis Artifacts for: Analyzing Environmental Data with the Titan Platform A detailed description can be found in the README.md. The corressponding thesis can be found here. Abstract The natural environment is one of our biggest treasures ― if not our biggest treasure ― and it must be preserved. Therefore, understanding our natural environment is becoming increasingly important as we struggle to respond to the implications of climate change and new diseases. Climate change is the greatest challenge faced by almost every species. With the help of environmental data, we can understand most of the complex interrelationships present in the climate and consequently take preventive measures. However, with the rise of new technologies, the collection of environmental data has become very rapid and complex, and therefore, it is difficult or even impossible to process them using traditional methods. To overcome this problem, it is important to extract pieces of information from the data as soon as they are produced. We used Titan, a software that applies stream processing, to analyze the environmental data collected across Germany. Titan comes with a set of solutions that facilitate the processing of huge amounts of data and allow software components to consume and supply data. In this work, three data sources have been connected directly to the Titan platform to collect diverse types of data. Once these connections were established, we analyzed the incoming data on the Titan platform using a set of data flows that consist of modular components connected to each other. Each modular component is responsible for a single task, such as data collection, data filtering, or data transformation. Moreover, we connect an external database to the platform to save the results of our analysis. Finally, we used a visualization tool to, create a dashboard for each flow implemented on the platform. We evaluate the scalability of the Titan platform based on the number of incoming records. To do so, we continuously increase the amount of workload into the Titan platform and determine the minimum number of component instances that are necessary to process data without reaching high traffic of data across the platform.

description: This paper presents a parallel genetic algorithm for three dimensional bin packing with heterogeneous bins using Hadoop Map-Reduce framework. The most common three dimensional bin packing problem which packs given set of boxes into minimum number of equal sized bins is proven to be NP Hard. The variation of three dimensional bin packing problem that allows heterogeneous bin sizes and rotation of boxes is computationally more harder than common three dimensional bin packing problem. The proposed Map-Reduce implementation helps to run the genetic algorithm for three dimensional bin packing with heterogeneous bins on multiple machines parallely and computes the solution in relatively short time.
