Assigning Triaged Patients To Treatment Rooms In A Hospital Emergency Department, Barry E. King E. King, Tyler Pollard, Jennifer Rice, Jane Siegler
Assigning Triaged Patients To Treatment Rooms In A Hospital Emergency Department, Barry E. King E. King, Tyler Pollard, Jennifer Rice, Jane Siegler

The assigning of new arrivals at a hospital emergency department to treatment rooms was examined. New patients are summarily triaged and assigned to a treatment room based on severity of their symptoms, the grade of a treatment room, and an exponential benefit curve that encourages the solver to schedule the most severe cases early. SAS’s OPTMODEL modeling language was employed to build the model and SAS’s MILP solver was used to perform the scheduling. Up to thirty patients were optimally assigned to depict the example of a large emergency department.

Using Machine Learning To Predict Sales Conditional On Bid Acceptance, Barry E. King, Jason Davidson

A North American provider of vehicle parking solutions seeks to predict if a bid will be successful and, for those that are successful, what will be the cumulative sales revenue. Both traditional statistical methods and machine learning algorithms were employed. The machine learning techniques performed better than the statistical methods. There is no statistically significant difference between random forest and extreme gradient boosting for either the binary classification task or the regression task.
The Impact Of State Fiscal Policy On States' Resilience Entering The Great Recession, Kathy A. Paulson Gjerde, Peter Prescott, Jennifer Rice

The U.S. economy entered the Great Recession in December 2007 and exited in June 2009. This national statistic obscures a wealth of state-level data shedding light on the policies and conditions that helped some states withstand that recessionary shock for a time. In this study, we used that state-level data in a parametric regression model, known as survival analysis, to estimate the effects that a state’s fiscal policy had on the timing of its entry into the Great Recession. Consistent with earlier, more general, studies focusing on economic growth, we found that taxes have the potential to hasten the start …
Go Global Or Stay Local? Understanding How Fiscal Incentives Reshape Supply Networks, Ricardo Silveira Martins, Janaina Siegler, Armando Souza-Junior, Barbara Flynn, Guilherme Silveira Martins

This study investigates the way firms reconfigure their supply base and reshape their production network to capture value from Free Trade Zone incentives to capture value from incentives. Six production networks located in Manaus, Brazil are analyzed using the Global Production Network framework and factors related to plant type and supplier relationships. A multiple case study was conducted. Data was collected using in-depth semi-structured interviews administered in loco, and the selected the firms were leaders in three different industries: transportation, mechanical assembly and chemicals. The results indicate that, if effectively applied, incentives can impact production network configuration from an embeddedness …
The Influences Of Locus Of Control, Debt, And Framing On Retirement Contributions, Bryan Foltice, Patrick Ilcin
The Influences Of Locus Of Control, Debt, And Framing On Retirement Contributions, Bryan Foltice, Patrick Ilcin

This study evaluates locus of control, debt, and framing effects as potential drivers of retirement savings decisions. We administer an online survey analyzing how much an individual will save for retirement upon graduating college. The study finds that individuals with an external locus of control contribute significantly less to their retirement savings than individuals with an internal locus of control. Interestingly, this study finds no significant relationship between debt overhang and initial contributions. To measure framing effects, participants were given the choice to change their initial contribution rate after seeing the estimated increased future amount of their account balance based …
Prenatal Stress And Birth Weight: Evidence From The Egyptian Revolution, Ronia A. Hawash
Prenatal Stress And Birth Weight: Evidence From The Egyptian Revolution, Ronia A. Hawash
Scholarship and Professional Work - Business
The Egyptian Revolution that ignited in January 2011 resulted in intense violent conflict between protestors and former regime allies. This generated a significant amount of fear and stress among people who lived in proximity to such events. We use this exogenous shock as a natural experiment to test the causal relationship between prenatal stress and birth weight. Governorate-level fatalities resulting from this conflict will be used as an exogenous indicator for prenatal stress. Using fixed effects and difference-in-difference analysis, results show that higher prenatal stress resulting from political conflict during the first and second trimesters of pregnancy has a …
Building Country-Specific Advantages (Csa): Understanding How Ftz Incentives Impact Strategic Plant Location And Buyer-Supplier Relationships, Armando Araújo Souza-Júnior, Ricardo Silveira Martins, Jane Siegler, Afrânio A. F. Soares-Filho

We explore how leading companies manage relationships in supply chains that are not formed by natural market forces. Rather, they were stimulated by exogenous forces, such as the Free Trade Zones that are created by the Government’s policy initiatives for purposes of regional development. We researched electronic industry in Manaus, located in the Brazilian Amazon Rain Forest. Multi-methods using qualitative, structured interviews, and quantitative approaches, structural modeling equation, were used. Results indicated that the companies settled for a location that they would not do under normal conditions and, secondly, that there was an expectation of externality as the makers of …
Misperception Of Exponential Growth: Are People Aware Of Their Errors?, Henning Cordes, Bryan Foltice, Thomas Langer
Misperception Of Exponential Growth: Are People Aware Of Their Errors?, Henning Cordes, Bryan Foltice, Thomas Langer

Previous research shows that individuals make systematic errors when judging exponential growth, which has harmful effects for their financial well-being. This study analyzes in how far individuals are aware of their errors and how these errors are shaped by arithmetic and conceptual problems. While arithmetic problems could be overcome by employing computational assistance like a pocket calculator, this is not the case for conceptual problems, a term we use to subsume other error drivers like a general misunderstanding of exponential growth or overwhelming task complexity. In an incentivized experiment, we find that participants strongly overestimate the accuracy of their intuitive …

In the last decades there has been great concern about sustainability, especially in companies, where the concept of sustainable development is no longer a trend, but a reality. In the logistics field it should not be any different, since it´s importance to the movement of goods and people. This movement is carried out by four transportation modals, road, air, rail and river. The road transportation is widely used in relation to the others, bringing some problems in large urban centers like traffic jams, climate change, pollution, high CO2 emissions, among others. Thus, it is currently a great challenge to make …
