Essays On Horizontal Divestitures And Product Market Relationships, Norkeith Ervin Smith

Wayne State University Dissertations

This dissertation is the first to study the product effect of horizontal divestitures on upstream and downstream firms. This first essay examines product market impact of a sample of horizontal asset sales from 1988 to 2005 on corporate customers, suppliers, and industry rivals. I create a sample of firms that classifies corporate customers, suppliers, and industry competitors of firms proposing horizontal asset sales, and employ this data set to investigate the wealth effects at announcement. This study also considers post-divestiture changes in abnormal operating performance for divesting firms, customers, and suppliers.

I document evidence that divestiture related wealth effects for …

An Investigation Of The Relationship Between Axonal Injury, Biomarker Expression And Mechanical Response In A Rodent Head Impact Acceleration Model, Yan Li

Wayne State University Dissertations

In the United States 1.4 million people sustain traumatic brain injury (TBI) each year, resulting in 235,000 hospitalizations and 50,000 fatalities annually. Traumatic axonal injury (TAI) is a serious outcome of TBI that accounts for 40-50% of hospitalizations due to head injury and one third of the mortality due to TBI, and it is difficult to diagnose and evaluate. The purpose of this dissertation is to determine mechanical injury predictors for TAI and identify potential biomarkers to evaluate TAI.

In this dissertation, a modified Marmarou impact acceleration injury model was developed to allow the monitoring of velocity of the impactor …

Closing The Gap: Greater Retention And Achievement Through Service-Learning At Wayne State University, Monita H. Mungo

Wayne State University Dissertations

Despite the ideals of the achievement ideology that invade every facet of American life, there remains a large population of people who are not able to access the basic tool – education – needed to make the American dream a reality. The lack of educational opportunities for Americans of color is an important social issue because their systemic exclusion from higher education has significant implications for America’s economic future beyond social justice and equality. Americans espouse the ideology of equality and opportunity, and the educational system has always been structured on the notion of preparing individuals with skills for the …

Novel Incorportation Of Biomedical Engineering Algorithms (Bispectral Index Guided Or Anesthetic Concentration Guided) In Real-Time Decision Support To Prevent Intraoperative Awareness Using An Electronic Anesthesia Information Mananagement System, Amy Melanie Shanks

Wayne State University Dissertations

Background: Intraoperative awareness with explicit recall (AWR) is a feared complication of surgery that can lead to significant psychological distress. Several large prospective trials have been completed comparing two methods of monitoring anesthetic depth [minimum alveolar concentration (MAC) or electroencephalography (EEG) monitoring using the bispectral index (BIS)] for the prevention of AWR. However, these trials were conducted in high risk populations, limiting generalizability.

Research Hypothesis: Real-time decision support with Anesthesia Information Management System alerts based on a novel anesthetic concentration algorithm (incorporating the use of intravenous anesthetics) or an EEG-guided algorithm will reduce the known incidence of AWR.

Methods: First, …
