Empirical Studies in Hospital Emergency Departments

EMPRICIAL STUDIES IN HOSPITAL EMERGENCY DEPARTMENTS Robert Johnson Batt Christian Terwiesch This dissertation focuses on the operational impacts of crowding in hospital emergency departments. The body of this work is comprised of three essays. In the rst essay, Waiting Patiently: An Empirical Study of Queue Abandonment in an Emergency Department, we study queue abandonment, or left without being seen. We show that abandonment is not only in uenced by wait time, but also by the queue length and the observable queue ows during the waiting exposure. We show that patients are sensitive to being "jumped" in the line and that patients respond di erently to people more sick and less sick moving through the system. This study shows that managers have an opportunity to impact abandonment behavior by altering what information is available to waiting customers. In the second essay, Doctors Under Load: An Empirical Study of State-Dependent Service Times in Emergency Care, we show that when crowded, multiple mechanisms in the emergency department act to retard patient treatment, but care providers adjust their clinical behavior to accelerate the service. We identify two mechanisms that providers use to accelerate the system: early task initiation and task reduction. In contrast to other recent works, we nd the net e ect of these countervailing forces to be an increase in service time when the system is crowded. Further, we use simulation to show that ignoring state-dependent service times leads to
Aflatoxin M 1 in UHT Cow Milk samples Collected in Burdur , Turkey Türkiye

Aflatoxins are secondary metabolites of toxigenic moulds of the Aspergillus species. Aflatoxin M1, a metabolite of the potent carcinogen aflatoxin B1 (AFB1) occurs in milk of animals consuming feed contaminated with AFB1. The aim of this study was to investigate the occurrence and levels of aflatoxin M1 (AFM1) in UHT milk samples consumed in Burdur city markets. In 2018, a total of 78 UHT milk samples were randomly collected from different markets of Burdur. The occurrence and contamination levels of AFM1 in the samples were investigated by the competitive enzyme-linked immunosorbent assay (ELISA) method. Aflatoxin M1 was detected in 24 of 78 samples (30.77%) in concentrations between 4.30-127.44 ng/L (mean level: 47.54 ng/L). AFM1 levels in 11 of these 24 positive samples were above legal limits of Turkey which is 50 ng/L for milk samples. It is concluded that the occurrence of AFM1 in milk samples in particular may be considered as a possible hazard for public health.

Internationalization using Domain Translator

The paper presents the concept of the Domain Translator (DT) and the example of its implementation for the purpose of web sites internationalization. The majority of Croatian web sites, especially in the domain of academic community, offer only their narrowed versions containing some general information in foreign languages. The users that do not speak Croatian try to cope with this problem by using translators like Google Translate1, but only with a limited success, because of various problems, including the loss of local heritage like local names, shortcuts, and appropriate textual context. In the scope of this paper, a Domain Translator in a form of web browser extension was built, as well as the database of lexical artifacts covering an example of faculty web site. Given translations were compared with the corresponding results of the Google Translate and Bing Translator2.
Distributed malware detection

Widespread usage of broadband Internet connections has allowed the birth of a new threat against service providers and subscribers as well. Botnets are vast networks of compromised hosts under the control of single masters who possess the ability to launch crippling denial of service attacks, send vast quantities of unsolicited e-mail messages and infect thousands of vulnerable systems with privacy-violating spyware and other forms of malicious software. Our goal is to propose a distributed architecture and introduce novel algorithms for malicious (potential botnet) activity recognition based on network traffic statistics generated by NetFlow. Scalability and robustness were the main principles during the design of the architecture. In this paper, we demonstrate that we are able to reduce the number of NetFlow records significantly with an aggregation scheme. Furthermore, we are able to detect botnet participant computers (zombies) with the help of aggregated samples originating from other networks, while the algorithms provide utmost anonymity to participants.
Measurement of Dilute Mixture Vapor-Liquid Equilibrium Data for Methanol-Water and Ethanol-Water Mixtures with a Recirculating Still

A Gillespie-type still which recirculates vapor and liquid phases was used in the measurement of pressure and phase compositions for dilute aqueous solutions of methanol and ethanol at vapor-liquid equilibrium at temperatures between 50 and 100 °C. Liquid and condensed vapor samples from each run were analyzed for alcohol concentration by gas chromatography. Liquid activity coefficients calculated with the experimental data are compared with infinite dilution activity coefficients reported in the literature. The measured infinite dilution activity coefficients agree within 5% with independent measurements at the lower temperatures and are well represented by curves with slopes that agree with experimental enthalpy of mixing data. The curves, when extrapolated to lower temperatures, agree within 8.5 and 5.5%, respectively, of the mean values of numerous measurements for aqueous solutions of methanol and ethanol. Introduction Activity coefficients are measures of the deviation from ideal distribution of components between equilibrium phases. Limiting values of activity coefficients (at infinite dilution) are useful in calculating phase concentrations for dilute mixtures and in correlating phase equilibrium models [1]. Several experimental methods have been used to measure activity coefficients at infinite dilution including gas chromatography, ebulliometry, and static pressure measurements [2]. A technique which has rarely been used for dilute mixtures [3,4] is that of analysis of vapor and liquid phases sampled from a recirculating still. Sampling from a recirculating still provides a simple, direct experimental technique to measure vapor-liquid equilibrium data for dilute mixtures given an accurate method of analysis of the liquid and condensed vapor samples. This work demonstrates the feasibility of using a recirculating still in the measurement of equilibrium pressure, temperature, and liquid and vapor phase compositions of dilute

VALIDATION OF ASSESSMENT OF BMI-1 ON PROTEIN AND MOLECULAR LEVELS IN ORAL DYSPLASIA AND SQUAMOUS CELL CARCINOMA. (A DIAGNOSTIC STUDY)

Background: B-cell–specific moloney murine leukemia virus integration site 1(BMI-1), a member of the polycomb group (PcG) genes, is considered to be pivotal in regulating stemness-related genes involved in maintaining the self-renewal ability of stem cells by promoting chromatin modifications. BMI-1 also played a significant role in cancer etiology for its involvement in pathological progress such as epithelial–mesenchymal transition (EMT) and cancer stem cells (CSCs) maintenance, propagation, and differentiation. Aim of the study: is to detect BMI-1 immunohistochemical expression and assess its mRNA level in normal oral mucosa, different grades of oral epithelial dysplasia (OED) and oral squamous cell carcinoma (OSCC) as well as to correlate BMI-1 expression on protein and gene levels with different grades of OED and OSCC to detect which of them is more reliable the gene or the protein level. Materials and Methods: A total of 40 archival paraffin embedded tissue samples divided into 3 groups: control, OED and OSCC. The OED group was further subdivided into (mild, moderate, severe) also the OSCC group was subdivided into (well, moderate, poorly differentiated) for immunohistochemical study and RTPCR. Results: we found that the normal oral mucosa group showed scattered nuclear immunoexpression of BMI-1 localized to the basal and parabasal layers. In OED group, BMI-1 showed diffuse nuclear expression in addition to, cytoplasmic immunoexpression among all subgroups. In OSCC group, nuclear and cytoplasmic immunoexpression was also observed. One-way ANOVA test was used to assess the nuclear count, area percent as well as mRNA level among the groups collectively and within the studied subgroups. High statistical significance was observed among all the groups collectively regarding different techniques. However, within the subgroups only the nuclear count can have statistical significance within the studied subgroups. Conclusion: Nuclear count assessment of BMI-1 is an accurate and reliable technique that can be used in the early diagnosis of OED and OSCC as well as identification of patients at high risk of malignant transformation.
Banks' balance sheet, uncertainty and macroeconomy

Motivated by data on weak credit growth despite highly accommodative monetary policy in many advanced economies and by ample evidence on important effects of uncertainty in the course of the fi nancial crisis of 2007-2009, this paper studies relationships between economic uncertainty and the volume of bank lending. We obtain empirical evidence showing that an increase in uncertainty leads to reallocation of portfolio of assets by commercial banks: banks reduce issuance of loans, in particular, of commercial and industrial loans, while increasing the stock of safe assets - cash and Treasury and agency securities. The objective of the paper is to account for this evidence in a general equilibrium theoretical setup and to evaluate the importance of bank portfolio allocation effects on macroeconomy following a spike of uncertainty. DSGE model with portfolio-optimizing banking sector. We propose a DSGE model that incorporates a portfolio-optimizing banking sector facing non-diversifiable credit risk, where banks' attitude to risk and expected profitability help to explain the endogenous movements of the risk premium. Precautionary mechanism is in play: lending rate charged by risk-averse banks provides self-insurance from expected profitability reduction, brought about by heightened uncertainty about entrepreneurial productivity, in addition to remunerating for risk of defaults. Banks reduce their exposure to credit risk by cutting down the share of risky lending in their asset portfolios and increasing the share of risk-free assets. Variations in risk premium make the effect on economy via changing entrepreneurial demand for capital, such that financial accelerator mechanism is active.

MEDIATION BETWEEN DIGITAL SURROGATES AND VIEWERS BASED ON THE TECHNOLOGY ACCEPTANCE MODEL 1

This study investigates the values of engaging with digital surrogates, including Van Gogh Inside (VIE; 2016), Monet’s Impression Exhibition 2016 (MIE; 2015–16), and Hello Michelangelo (2016-2017), based on a Technology Acceptance Model (TAM). Both usability for learning and usability for appreciation in perceived usefulness have significant correlations with the degree of satisfaction (DOS) and degree of immersion (DOI). Our findings show that the DOS not only has a significant correlation with the DOI but also influences the intention to use digital surrogates (intention to visit the exhibition, recommend the exhibition, and intention to visit digital exhibition) in all digital surrogates. It was found that the perceived ease of use has an influence on DOS and DOI in the case of VGI and MIE. This study unveils an insight on the values and qualities associated with the digital surrogates to evoke a sense of authentic experience as well as foster learning. In addition, it also demonstrates the suitability of TAM as an evaluation model for digital surrogates of remediating the originals.
Numerical study of brash ice loads on ship hulls based on DEM-CFD

The brash ice loads on ship hulls are studied by coupling Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD). The loads induced by brash ice on ship hulls and the interactions between ice floes are investigated by DEM. The hydrodynamics of ice floes, mainly including the drag force and the buoyance, is calculated by CFD. In the simulation, the ice floes are treated as discrete elements, and the ship hull is treated as rigid body with a certain speed. The contact forces between ice floes and ship hulls are determined by the Hertz-Mindlin (no-slip) contact model. The shape of ice floes is an approximate square composed of a number of spherical faces, which can reduce the computation cost. A validation of this method by comparison with the experiment data is presented. The numerical results show qualitative agreement with the experiment result. The reasons of deviations between numerical results and experiment data are discussed.
Liquidity-adjusted Capital Asset Pricing Model In Indian Stock Market

Capital Asset Pricing Model propounded by Sharpe considers only market risk as the predictor of expected return and significantly excludes all other risks including liquidity risk. This paper aims at constructing liquidity – adjusted CAPM for Indian stock market by considering five-minute quotation data. Employing Fama – MacBeth crosssectional regression, it is proved that the liquidity risk and expected liquidity are priced in the Indian stock market. It provides that the liquidity shocks can have significant inferences on portfolio diversification strategies to be adopted

Nation Scale Mobile Ad Hoc Network for Normally Isolated Topologies

When network infrastructure is down after disasters such as hurricane Maria, inaccessible due to extreme censorship or nonexistent in remote areas without infrastructure, novel solutions for large scale delay tolerant communications are needed. Nation Scale Mobile Ad Hoc Network, or NSHoc, enables smartphone users to request and receive content via opportunistic encounters at nation scale with no prior knowledge of network members and in sparse topologies where individual nodes may remain isolated for minutes or even hours at a time. We call such sparse topologies normally isolated. It does so by leveraging mobile ad hoc networks that rely on opportunistic encounters between users to distribute content. We use a custom simulator to test the system over two nation scale topologies: Puerto Rico and Syria. With 10K users, NSHoc can deliver over 95% of the requested content to over 97% of users in 143 locations spread throughout Puerto Rico in less than 5 hours on average with a total throughput of . 42 pieces of content per second. Significantly, these results are not simply the consequence of popular content being cached. We demonstrate that requests for unpopular content are also satisfied due to the benefits of ubiquitous caching. In addition, we show that NSHoc remains performant across a variety of topologies, mobility models, and content distributions. No known prior work considers such large scale, sparse topologies. This work shows that MANETs are an attractive alternative for distributing content at nation scale in the face of infrastructure loss even when users are normally isolated.
Obstetric Outcomes of Syrian Refugees and Turkish Citizens.

BACKGROUND To present the differences in prenatal, labor and neonatal outcomes for Syrian refugees and Turkish citizens. METHODS Between January 2013 and December 2016, all patients in our hospital were screened retrospectively. Totally, 17000 pregnant women included in the study were divided into three groups: group 1: 4802 pregnant in Syrian refugees group; group 2: 6752 pregnant in the low-income Turkish citizens (LI groups); and group 3: 5446 women in high-income Turkish citizens (HI groups). The groups were compared for demographic parameters, prenatal, labor and postnatal results. RESULTS Age, gestational week, birth weights, antenatal follow-up, antenatal iron supplementation and prenatal hemoglobin (Hb) values were significantly lower in the Syrian refugee group (P < 0.001). Only moderate preterm delivery and moderate low birth weight were higher in the refugee group (P = 0.023 and P = 0.001). Stillbirth rates were similar in all three groups (P = 0.203), but all other neonatal complications were higher in the Turkish citizens group. CONCLUSION In comparison to non-refugee control patients, adverse perinatal outcomes were not observed in pregnant refugees. The refugee health policies of the Republic of Turkey seem to be working. However, further larger multicenter studies may provide more convincing data about obstetric outcomes and health results in the Syrian refugee population.
Cohomology and Support Varieties for Classical Lie Superalgebras

Classical Lie superalgebras arise in the physical theory of supersymmetry and behave analogously to Lie algebras in the theory of algebraic groups. In the theory of Lie algebras, the Koszul resolution is finite, meaning relative cohomology rings are finite as a vector space over the field. For Lie superalgebras, the Koszul resolution is infinite. A theorem of Boe-Kujawa-Nakano states that for classical Lie superalgebras, the cohomology ring relative to the even component has finite Krull dimension, and the structure of this cohomology ring is determined by the invariant theory of a reductive group’s action on a vector space. This realization opens the door to the study of the support variety theory for classical Lie superalgebras. The main result of this thesis is a generalization of the result of Boe-Kujawa-Nakano. The main theorem asserts that the cohomology ring of a classical Lie superalgebra relative to any even subsuperalgebra has finite Krull dimension, and is indeed a finite extension of a subquotient of the Boe-Kujawa-Nakano cohomology ring via restriction. The proof of the main theorem relies on a spectral sequence inspired by that of Hochschild-Serre. The spectral sequence used to prove finite generation proves to be an invaluable tool in analyzing the behavior of cohomology rings. An example is presented in which the Krull dimension of a relative cohomology ring is positive but not equal to the Krull dimension of Boe-Kujawa-Nakano cohomology. Conditions are given for when the cohomology ring will be Cohen-Macaulay. With finite-generation established, the final chapter of this dissertation is devoted to studying the relative support variety theory for modules. A realization morphism induced by restriction of functions plays a role similar to that of Friedlander-Parshall’s realization morphism for restricted Lie algebras. The main goal of this chapter is to work towards a conjectural tensor product theorem for Lie superalgebras, which would generalize results of Grantcharov-Grantcharov-Nakano-Wu. To this end, rank varieties are introduced which conjecturally generalize the rank varieties of Grantcharov-Grantcharov-Nakano-Wu.
