Teaching The Foundations Of Data Science: An Interdisciplinary Approach, Daniel Asamoah, Derek Doran, Shu Z. Schiller

Derek Doran

The astronomical growth of data has necessitated the need for educating well-qualified data scientists to derive deep insights from large and complex data sets generated by organizations. In this paper, we present our interdisciplinary approach and experiences in teaching a Data Science course, the first of its kind offered at the Wright State University. Two faculty members from the Management Information Systems (MIS) and Computer Science (CS) departments designed and co-taught the course with perspectives from their previous research and teaching experiences. Students in the class had mix backgrounds with mainly MIS and CS majors. Students' learning outcomes and post ...


Volume And Cost Implications Of Product Portfolio Complexity, Mark A. Jacobs 2016 University of Dayton

Volume And Cost Implications Of Product Portfolio Complexity, Mark A. Jacobs

Mark Jacobs

Business leaders are concerned about the impacts of increasing levels of product portfolio complexity since many sense that complexity related costs such as order management, procurement, and inventory threaten to undermine operational efficiencies and consume profits. Even so, managers do not fully understand the extent and breadth of the impacts of product portfolio complexity. A more complete understanding of the operational effects of product portfolio complexity is lacking partially because researchers have not yet offered a robust theoretical perspective or studied it in a focused controlled way; until now. Herein, measures of product portfolio complexity are developed and related to ...


Procurement Fraud, Lisa McNamee 2016 La Salle University

Procurement Fraud, Lisa Mcnamee

Economic Crime Forensics Capstones

The 2016 Global Economic Crime Survey conducted by PricewaterhouseCoopers LLP (2016), states that twenty-two percent of companies have experienced procurement fraud. The statistics have actually decreased since 2014 when twenty-seven percent of companies had experienced procurement fraud. However, procurement fraud is still one of the most costly fraudulent schemes. Despite the reduction, the Department of Defense continues to experience large procurement fraud cases, both in number and dollar value. A recent example is the Supreme Foodservice fraud case, which cost the Defense Logistics Agency $757 million dollars in fraudulent charges. (Jahner, 2014) The Department of Defense Office of Inspector General ...


First-Case Operating Room Delays: Patterns Across Urban Hospitals Of A Single Health Care System, Callie M. Cox Bauer, Danielle M. Greer, Kiley B. Vander Wyst, Scott A. Kamelle 2016 United States Air Force San Antonio Military Medical Center

First-Case Operating Room Delays: Patterns Across Urban Hospitals Of A Single Health Care System, Callie M. Cox Bauer, Danielle M. Greer, Kiley B. Vander Wyst, Scott A. Kamelle

Journal of Patient-Centered Research and Reviews

Purpose

Operating room delays decrease health care system efficiency and increase costs. To improve operating room efficiency in our system, we retrospectively investigated delay frequencies, causes and costs.

Methods

We studied all first-of-the-day nonemergent surgical cases performed at three high-volume urban hospitals of a large health system from July 2012 to November 2013. Times for patient flow from arrival to procedure start and documented reasons for delay were obtained from electronic medical records. Delay was defined as patient placement in the operating room later than scheduled surgery time. Effects of patient characteristics, late patient arrival to the hospital, number of ...


How Cios Overcome The Competing Values Challenge: Irish Cios’ Perspectives, Harvey Enns, Dean B. McFarlin, Paul B. Sweeney 2016 University of Dayton

How Cios Overcome The Competing Values Challenge: Irish Cios’ Perspectives, Harvey Enns, Dean B. Mcfarlin, Paul B. Sweeney

Paul B. Sweeney

Competing values are a fact of organizational life. However, there are gaps in our understanding about how these opposing beliefs hinder influence processes. This article draws on interview data to demonstrate how Irish Chief Information Officers (CIOs) are able to convince their colleagues to support new projects within their firms in the face of competing values. Focused interviews were used to explore the influence process and the competing values phenomenon, since this type of research is at an early stage and qualitative methods and analysis serve as a rich source of theory development.

The data showed that the CIOs who ...


Integrating Strategic And Tactical Rolling Stock Models With Cyclical Demand, Michael F. Gorman 2016 University of Dayton

Integrating Strategic And Tactical Rolling Stock Models With Cyclical Demand, Michael F. Gorman

Michael F. Gorman

In the transportation industry, companies position rolling stock where it is likely to be needed in the face of a pronounced weekly cyclical demand pattern in orders.

Strategic policies based on assumptions of repetition of cyclical weekly patterns set rolling stock targets; during tactical execution, a myriad dynamic influences cause deviations from strategically set targets. We find that optimal strategic plans do not agree with results of tactical modeling; strategic results are in fact suboptimal in many tactical situations. We discuss managerial implications of this finding and how the two modeling paradigms can be reconciled.


Pricing And Product Mix Optimization In Freight Transportation, Michael F. Gorman 2016 University of Dayton

Pricing And Product Mix Optimization In Freight Transportation, Michael F. Gorman

Michael F. Gorman

We propose improved pricing and market mix can improve the profitability of the freight transportation provider through the reduction of equipment repositioning costs. We hypothesize that because of complexities surrounding pricing and equipment repositioning costing, existing pricing strategies in freight transportation fail to fully consider these costs. We test this hypothesis in an applied setting in which Monte Carlo simulation captures the stochasticity of market conditions inherent in the problem. We use a heuristic to improve the nondifferentiable, discontinuous objective function.

Our results from test cases show with high confidence that current prices are not optimal, as indicated by a ...

Irish Cios’ Influence On Technology Innovation And It-Business Alignment, Harvey Enns, Joseph J. McDonagh 2016 University of Dayton

Irish Cios’ Influence On Technology Innovation And It-Business Alignment, Harvey Enns, Joseph J. Mcdonagh

Harvey Enns

Technology is the driving force behind many of today’s new products, services, and cost-cutting measures. However, there are gaps in our understanding about how technological innovation is fostered and nurtured in organizations. Part of the answer is to examine how Chief Information Officers (CIOs) exercise influence regarding technological innovation in organizations. This is particularly important since the CIO is the head of technology in organizations, an important source of technological innovation. This article draws on an established executive influence framework to demonstrate how Irish CIOs are able to solidify Information Technology’s (IT’s) contribution to technological innovation via ...


Synergy And Its Limits In Managing Information Technology Professionals, Thomas W. Ferratt, Jayesh Prasad, Harvey Enns 2016 University of Dayton

Synergy And Its Limits In Managing Information Technology Professionals, Thomas W. Ferratt, Jayesh Prasad, Harvey Enns

Harvey Enns

We examine the effects of human resource management (HRM) practices (e.g., career development, social support, compensation, and security) on IT professionals‟ job search behavior. Job search is a relatively novel dependent variable in studies of voluntary withdrawal behavior, in general, and for IT professionals, in particular. From a universalistic perspective, HRM practices individually and in combination exhibit independently additive effects on job search behavior. Our study contrasts this perspective with configurational theory, hypothesizing that proposed idealtype configurations of HRM practices have synergistic effects on job search behavior. We contribute to the IT and broader HRM literature by theoretically explicating ...


Assessing The Emphasis On Information Security In The Systems Analysis And Design Course, William David Salisbury, Thomas W. Ferratt, Donald E. Wynn 2016 University of Dayton

Assessing The Emphasis On Information Security In The Systems Analysis And Design Course, William David Salisbury, Thomas W. Ferratt, Donald E. Wynn

William D Salisbury PhD

Due to several recent highly publicized information breaches, information security has gained a higher profile. Hence, it is reasonable to expect that information security would receive an equally significant emphasis in the education of future systems professionals. A variety of security standards that various entities (e.g., NIST, COSO, ISACA-COBIT, ISO) have put forth emphasize the importance of information security from the very beginning of the system development lifecycle (SDLC) to avoid significant redesign in later phases. To determine the emphasis on security in typical systems analysis and design (SA&D) courses, we examine (1) to what extent security is ...

Newsvendor Models With Monte Carlo Sampling, Ijeoma W. Ekwegh 2016 East Tennessee State University

Newsvendor Models With Monte Carlo Sampling, Ijeoma W. Ekwegh

Electronic Theses and Dissertations

Newsvendor Models with Monte Carlo Sampling by Ijeoma Winifred Ekwegh The newsvendor model is used in solving inventory problems in which demand is random. In this thesis, we will focus on a method of using Monte Carlo sampling to estimate the order quantity that will either maximizes revenue or minimizes cost given that demand is uncertain. Given data, the Monte Carlo approach will be used in sampling data over scenarios and also estimating the probability density function. A bootstrapping process yields an empirical distribution for the order quantity that will maximize the expected profit. Finally, this method will be used ...


The Influence Of The Electric Supply Industry On Economic Growth In Less Developed Countries, Edward Richard Bee 2016 University of Southern Mississippi

The Influence Of The Electric Supply Industry On Economic Growth In Less Developed Countries, Edward Richard Bee

Dissertations

This study measures the impact that electrical outages have on manufacturing production in 135 less developed countries using stochastic frontier analysis and data from World Bank’s Investment Climate surveys. Outages of electricity, for firms with and without backup power sources, are the most frequently cited constraint on manufacturing growth in these surveys.

Outages are shown to reduce output below the production frontier by almost five percent in Africa and by a lower percentage in South Asia, Southeast Asia and the Middle East and North Africa. Production response to outages is quadratic in form. Outages also increase labor cost, reduce ...

A Simulation Model Of The “Bio-Depot” Concept In The Context Of Components Of Variance And The “Taguchi Loss Function”, Maximilian Platzer

Masters Theses

The research focuses on the simulation, statistical evaluation, costs, and continuous improvement of supply chains for bio-based materials. A significant challenge of using cellulosic feedstocks for biofuel or bioenergy production is the high per unit costs of final products, e.g., biofuels. The goal of the research is to provide practitioners with useful statistical methods and a simulation Excel template for evaluating the variance and costs associated with the supply chain of bio-based products. Statistical Process Control (SPC), components of variance, Taguchi Loss Function, and reliability block diagrams (RBD) are used in this thesis for the evaluation of the supply ...

Capacity Management In Agricultural Commodity Processing And Application In The Palm Industry, Onur BOYABATLI, Quang (Jason) Dang NGUYEN, Tong WANG 2016 Singapore Management University

Capacity Management In Agricultural Commodity Processing And Application In The Palm Industry, Onur Boyabatli, Quang (Jason) Dang Nguyen, Tong Wang

Research Collection Lee Kong Chian School Of Business

This paper examines the capacity investment decisions of a processor that uses a commodity input to produce both a commodity output and a byproduct in the context of agricultural industries. We employ a multi-period model to study one-time processing and (output) storage capacity investment decisions--in addition to periodic processing and inventory decisions--when both input and output spot prices as well as production yield are uncertain. Using a calibration based on the palm industry, we find that if the yield uncertainty is ignored in capacity planning, then basing those plans on average yield is preferable to basing them (as often occurs ...

Impact Of Country Personality On Attitude Toward Foreign Products : Self-Congruity As A Mediator, Murat Aktan, Paul W. Chao 2016 Nevsehir Haci Bektas Veli University

Impact Of Country Personality On Attitude Toward Foreign Products : Self-Congruity As A Mediator, Murat Aktan, Paul W. Chao

Atlantic Marketing Journal

This research examines the direct effect of country personality (CP) on consumer product attitude and indirect effect through consumer self-congruity between CP and his/her own self-concept on product attitude in an emerging country- Turkey. We propose an integrated structural equation model to examine the relationships. Measurement scales for CP, self-congruity and attitude are developed whose validities and reliabilities are confirmed by exploratory (EFA) and confirmatory (CFA) factor analyses with data collected from a sample of consumers in Turkey on two countries: USA and China.

The results reveal that four out of the original six dimensions of CP remain after ...
