Do Hospital Mergers Reduce Waiting Times? Theory And Evidence From The English Nhs, Vanessa Cirulli, Giorgia Marini, Marco Antonio Marini, Odd Rune Straume

Fondazione Eni Enrico Mattei Working Papers

We analyse – theoretically and empirically – the effect of hospital mergers on waiting times in healthcare markets where prices are fixed. Using a spatial modelling framework where patients choose provider based on travelling distance and waiting times, we show that the effect is theoretically ambiguous. In the presence of cost synergies, the scope for lower waiting times as a result of the merger is larger if the hospitals are more profit-oriented. This result is arguably confirmed by our empirical analysis, which is based on a conditional flexible difference-indifferences methodology applied to a long panel of data on hospital mergers …

Regulation Of Cora, The Magnesium, Nickel, Cobalt Transporter, And Its Role In The Virulence Of The Soft Rot Pathogen, Pectobacterium Versatile Strain Ecc71, Caleb M. Kersey, Korsi Dumenyo

Agricultural and Environmental Sciences Faculty Research

Pectobacterium versatile (formally P. carotovorum) causes disease on diverse plant species by synthesizing and secreting copious amount of plant-cell-wall-degrading exoenzymes including pectate lyases, polygalacturonases, cellulases, and proteases. Exoenzyme production and virulence are controlled by many factors of bacterial, host, and environmental origin. The ion channel forming the magnesium, nickel, and cobalt transporter CorA is required for exoenzyme production and full virulence in strain Ecc71. We investigated CorA’s role as a virulence factor and its expression in P. versatile. Inhibiting the transport function of CorA by growing a CorA+ strain in the presence of specific CorA inhibitor, cobalt (III) hexaammine (Co …

Estimating Body Weight And Body Condition Score Of Mature Beef Cows Using Depth Images, Yijie Xiong, Isabella C.F.S. Condotta, J. A. Musgrave, Tami M. Brown-Bandl, J. Travis Mulliniks

Department of Animal Science: Faculty Publications

Obtaining accurate body weight (BW) is crucial for management decisions yet can be a challenge for cow–calf producers. Fast-evolving technologies such as depth sensing have been identified as low-cost sensors for agricultural applications but have not been widely validated for U.S. beef cattle. This study aimed to (1) estimate the body volume of mature beef cows from depth images, (2) quantify BW and metabolic weight (MBW) from image-projected body volume, and (3) classify body condition scores (BCS) from image-obtained measurements using a machine-learning-based approach. Fifty-eight crossbred cows with a mean BW of 410.0 ± 60.3 kg and were between 4 …

Sales, Sungsoon Lim, Eric W. Peng, Puragra Guhathakurta, Joel Roediger, Kaixiang Wang, J. Christopher Mihos, Patrick Côté, Patrick R. Durrell, Laura Ferrarese

Pacific Faculty Work

We present Keck/DEIMOS spectroscopy of the first complete sample of ultradiffuse galaxies (UDGs) in the Virgo cluster. We select all UDGs in Virgo that contain at least 10 globular cluster (GC) candidates and are more than 2.5σ outliers in scaling relations of size, surface brightness, and luminosity (a total of 10 UDGs). We use the radial velocity of their GC satellites to measure the velocity dispersion of each UDG. We find a mixed bag of galaxies, from one UDG that shows no signs of dark matter, to UDGs that follow the luminosity-dispersion relation of early-type galaxies, to the most extreme …

Auditory Development In Beginner Elementary Strings Classes, Lydia Y. Cooley

Masters Theses

Integrating auditory and visual learning is vital in instrumental music instruction. There is an order of precedence that guides the teaching sequence to raise students who can hear and read the music they play. In order to teach students to think musically while reading notation important auditory preparation needs to take place. It should not occur via passive listening but via active music-making. This practice-based method creates experiential knowledge of music which can then lead to a conceptual understanding of musical symbols. Such practical engagement produces positive long-term effects on the depth of skill and the emotional state of the …

Apologetics And Popular Culture Phenomena: A Critique Of Ted Turnau's Method Concerning Anime, Matthew Hunter Hamilton

Masters Theses

Limited work has been performed in the field of Christian apologetics and popular culture, much less the intersection between anime and Christian apologetics. One scholar who has attempted to broach this gap has been Ted Turnau, who has developed a five-step diagnostic method for apologetically engaging popular culture phenomena. However, his method contains key flaws. Using the work of Thomas Lamarre, a scholar in the field of anime studies, a central contention will be made: that the material and technology of anime have processes that affect how viewers inhabit and orient themselves in the world, which in turn influences their …

A Speech On The Principles Of Social Freedom, Delivered In Steinway Hall, Monday, Nov. 20, 1871, Victoria C. Woodhull, Paul Royster (Editor)

Zea E-Books in American Studies

Spiritualist, stockbroker, publisher, activist for women’s suffrage, equal rights, and “free love,” Victoria Claflin Woodhull (1838 –1927) was the first woman nominated to run for President of the United States. The Principles of Social Freedom was delivered to a packed New York City audience in 1871. It called for a revolution in the legal, social, and sexual situation of women, for their liberation from the “despotic” control of men, and for their social freedom to live and love as they might choose. Mrs. Woodhull based this radical reimagining of social norms on America’s own values of freedom and equality, and …

Applicability Of Bio-Adsorbents Synthesized From Maize/Corn Plant Residues For Heavy Metals Removal From Aquatic Environments: An Insight Review, Jonas Bayuo, Mwemezi J. Rwiza, Kelvin Mark Mtei

All Rsif Scholars' Publications

The underutilization of agricultural waste products in recent years has resulted in environmental issues owing to improper disposal. As a result, heavy metals removal from aqueous systems utilizing sorbent materials produced from agricultural wastes has received a lot of attention. The current study provides an insightful review of the use of bio-adsorbents synthesized from maize/corn residues to decontaminate various toxicants from wastewater. Although bio-adsorbents made from maize/corn residues have shown to be efficient in the sequestration of heavy metals from wastewater, no study has looked at hybrid bio-adsorbents made from various parts of the maize/corn plant.

Gama/Devils: Cosmic Star Formation And Agn Activity Over 12.5 Billion Years, Jordan C J D’Silva, Simon P. Driver, Claudia D P Lagos, Aaron S G Robotham, Sabine Bellstedt, Luke J M Davies, Jessica E. Thorne, Joss Bland-Hawthorn, Matias Bravo, Benne Holwerda, Steven Phillipps, Nick Seymour, Malgorzata Siudek, Rogier A. Windhorst

Faculty and Staff Scholarship

We use the Galaxy and Mass Assembly (GAMA) and the Deep Extragalactic Visible Legacy Survey (DEVILS) observational data sets to calculate the cosmic star formation rate (SFR) and active galactic nuclei (AGN) bolometric luminosity history (CSFH/CAGNH) over the last 12.5 billion years. SFRs and AGN bolometric luminosities were derived using the spectral energy distribution fitting code ProSpect, which includes an AGN prescription to self consistently model the contribution from both AGN and stellar emission to the observed rest-frame ultra-violet to far-infrared photometry. We find that both the CSFH and CAGNH evolve similarly, rising in the early Universe up to a …

Advantage Of Precision Metagenomics For Urinary Tract Infection Diagnostics, Sadia Almas, Rob E. Carpenter, Chase Rowan, Vaibhav Tamrakar, Rahul Sharma

Human Resource Development Faculty Publications and Presentations

Background: Urinary tract infections (UTIs) remain a diagnostic challenge and often promote antibiotic overuse. Despite urine culture being the gold standard for UTI diagnosis, some uropathogens may lead to false-negative or inconclusive results. Although PCR testing is fast and highly sensitive, its diagnostic yield is limited to targeted microorganisms. Metagenomic next-generation sequencing (mNGS) is a hypothesis-free approach with potential of deciphering the urobiome. However, clinically relevant information is often buried in the enormous amount of sequencing data.

Methods: Precision metagenomics (PM) is a hybridization capture-based method with potential of enhanced discovery power and better diagnostic yield without diluting clinically relevant …

Faculty Research, Scholarly, and Creative Activity

Plastic pollution is distributed patchily around the world's oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast distances during foraging and migration. However, the spatial overlap between petrels and plastics is poorly understood. Here we combine marine plastic density estimates with individual movement data for 7137 birds of 77 petrel species to estimate relative exposure risk. We identify high exposure risk areas in the Mediterranean and Black seas, and …

Tinto’s (1975) theory asserts that college students who experience an inadequate amount of social integration or view themselves as being of trivial value in the social and academic systems of a higher education institution, decrease in institutional …

The Warning Passages In Hebrews: Exhortations Written Using Deliberative Rhetoric To A Community Of Faith, Edgardo Rafael Báez

Doctoral Dissertations and Projects

Different interpretative approaches (historical-cultural, social-scientific, intertextual, oral-critical, rhetorical) and methodologies are applied when the so-called warning passages in the book of Hebrews get interpreted. Inevitably, these different interpretative methodologies have created different perspectives or views that the original author may not have intended and that the audience may not have gathered. The author of Hebrews was seeking to help the audience of his writings understand a new position through his extensive use of the Greek word κρείττων (kreittōn). Similarly, a Greek background is also evident because of the tremendous use of classical rhetoric within the Epistle. In addition, it is …
