College Students Use Social Networking Sites For Sharing With Friends, But Guess Who Else Is Looking?, Elizabeth C. Alexander, Fred Mader, Deanna Mader

Atlantic Marketing Journal

Abstract - Jobvite, a recruiting platform for the social web, reports from their annual 2012 survey of recruiters that 92% of U.S. companies are using social networking sites (SNS) for hiring purposes (Jobvit, 2012). Career Builder reported in 2009 that 45% of employers were using SNS to screen and research applicants (CareerBuilder, 2009). It is important that faculty and support staff working to place students, and the students themselves, understand the developments and practices in the use of social networking sites for job search and recruiting and the best methods, as well as detriments when marketing themselves. This study examines …

Using Focus Groups And Correspondence Analysis To Explore The Relationship Between Millennials’ Online Behavior And Their Opinions Of Online Reviews, James E. Stoddard, Michael Dotson, Neel Das

Atlantic Marketing Journal

This paper explores the relationship between millennials’ online behavior and their opinions of online reviews via the use of focus groups and correspondence analysis. The proposition was that millennials’ online behavior (including search behavior) is likely to have an effect on how they view online reviews. The correspondence analysis results suggest that millennials who spend more time online peruse a greater number of products. Further, relationships were found between millennials’ time online and factors influencing review trustworthiness as well as millennials’ time online and factors affecting review memorability. It is noteworthy to suggest that focus group analysis can be enhanced …

Optimality Of The Fastest Available Server Policy, William P. Millhiser, Charu Sinha, Matthew J. Sobel

Business Faculty Articles and Research

We give sufficient conditions under which a policy that assigns customers to the Fastest Available Server, labelled FAS, is optimal in queueing models with multiple independent Poisson arrival processes and heterogeneous parallel exponential servers. The criterion is to minimize the long-run average cost per unit time. We obtain results for loss models and for queueing systems with a finite-capacity or infinite-capacity buffer under a head-of-the-line priority scheme. The results depend on cost assumptions, so we analyze the robustness of the cost structure and present counter-examples to illustrate when FAS is not optimal.

The Impact Of Urban Sprawl On Journey To Work Times For Mass Transit And All Other Commuters In The United States: A Research Note, Thomas E. Lambert, Hokey Min, Kyle Dorriere

Faculty and Staff Scholarship

As government budgets get tighter, there has been considerable public outcry about the continued investment in public mass transit systems and their financial viability. Amid this outcry, a number of studies have been conducted to determine which factors influence the use and efficiency of publicly-funded mass transit systems. These factors include population density and less sprawl (or greater urban compactness). However, their impact on mass transit usage is somewhat contradictory in that the heavy concentration of populations in the urban area and greater compactness is believed to increase mass transit usage due to a bigger number of potential passengers. In …

Improving The Nuclear Reform Implementation For Success, Allen Y. Agnes

Theses and Dissertations

This research identifies the method used for successful implementations. This method is critical to the nuclear enterprise as it will continually guide the program. Post-Cold War began an era of decline in the nuclear enterprise. Leaders were risk-averse in fear of being fired for making mistakes, the nuclear culture lost its experts, organizations were drawn to the conventional fight, and training lacked the priority necessary to rebuild the nuclear enterprise. In 2007 and 2008 two major incidents occurred, a necessary to bring focus and priority back to the nuclear enterprise. Several reports were accomplished to identify the issues and recommendations. …

Applying Lean To The Ac-130 Maintenance Process For The Royal Saudi Air Force, Fisal A. Alzahrani

Theses and Dissertations

The ideas expressed in this research come from the researchers experiences working in the AC-130 maintenance squadron in the Royal Saudi Air Force. The AC-130 maintenance process is not currently being used as effectively as it could be to make AC-130 fully mission capable. That can be done by improving communication, reducing distances needed to move or transport anything during the maintenance process and by efficient use of the available qualified workforces, tools and equipment. Consideration is given to applying an existing management technique to the Royal Saudi Air Forces AC-130 Maintenance Squadrons. The selected technique is the Lean management …

The Influence Of Education And Experience Upon Contextual And Task Performance In Warehouse Operations, Allen R. Miller

Theses and Dissertations

Supply chain workers make observable, preventable errors while completing their assigned tasks in the shipping process. Previous research has indicated that individuals with a greater grasp of their work and better system knowledge are less likely to commit interpretation errors. We believe worker-performance may, likewise, be affected by an individuals knowledge of why and where they fit into a larger system defined as mission knowledge. To assess our research objectives, we conduct a controlled experiment with 100 workers in the Air Force supply career field to discern how mission clarity, that is, education, experience and subject characteristics affect pick and …

Managing Emergency Department Crowding Through Improved Triaging And Resource Allocation, Kum Khiong Yang, Sean Shao Wei Lam, Joyce M. W. Low, Marcus Eng Hock Ong

Research Collection Lee Kong Chian School Of Business

Long waiting times in emergency departments (EDs) not only reduce patients’ perceived quality of care, but also increase crowding which can adversely affect patients’ outcomes. Waiting time has been found to affect patients’ outcomes and is closely associated with delays in the provision of ancillary services to ED patients by the diagnostic/treatment laboratories. The focus of this study is to improve the flow of ED patients by testing alternative triage processes and capacity of physicians, triage nurses and laboratories. Three alternative triage processes are examined for managing the flow of ED patients through shared and dedicated laboratories across different utilization …

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 …

Systemic Risk In Financial Networks, Peng-Chu Chen

Open Access Dissertations

This thesis extends the literature of systemic risk in financial networks in two directions.

First, we develop a majorization-based tool to compare financial networks in terms of systemic losses with a focus on the implications of liability concentration. Specifically, we quantify liability concentration by applying the majorization order to the liability matrix that captures the interconnectedness of banks in a financial network. We develop notions of balancing and unbalancing networks to bring out the qualitatively different implications of liability concentration on the system's loss profile. An empirical analysis of the network formed by the banking sectors of eight representative European …

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 exports …

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 …

Omni-Channel Supply Chain Management: Assessing The Impact Of Retail Service Operations In The Retail Supply Chain, Simone Theresa Peinkofer

Graduate Theses and Dissertations

The traditional retail environment, which is characterized by a clear division between brick-and-mortar and non-brick-and-mortar retail channels, has been recently disrupted by developments in e-commerce and mobile technologies. The result has been the emergence of omni-channel retailing. Within the reality of this new retail environment, it has been proposed that retailers should develop the necessary capabilities to fulfill consumer demand from anywhere – the store, the distribution center, or via drop-shipping from a supplier – which leads to the emergence of new operational complexities and challenges in the retail supply chain. In light of the growing popularity of these new …

The Impact Of The Potential Entry Of Copycats: Entry Conditions, Consumer Welfare, And Social Welfare, Sarah Y. Gao, Wei Shi Lim, Christopher Tang

Research Collection Lee Kong Chian School Of Business

This article examines the implications of the potential entry of a copycat who produces and sells a copycat (i.e., imitation) product that competes with the incumbent product. By analyzing a two-period dynamic noncooperative game between these two firms, we identify conditions under which the copycat can gain successful market entry. More importantly, we find that the potential entry of a copycat creates (implicit) pressure for the incumbent to lower its selling price; hence, it improves consumer welfare. Finally, we identify conditions under which the potential entry of a copycat can increase social welfare (i.e., consumer welfare and the profit of …

Production Planning Using Evolving Demand Forecasts In The Automotive Industry, Hakan Yildiz, Scott Duhadway, Ram Narasimhan, Sriram Narayanan

Business Faculty Publications and Presentations

This paper considers an auto parts supplier who receives order release updates from its customers and revises its production plan for future periods on a weekly basis. The inaccuracy of the order releases causes significant costs in the form of premium expedited transportation, production overtime, and excess inventory. This setting provides a rich context for studying order release variance, because the supply chain has adopted a just-in-time (JIT) approach where ideal inventory levels are kept at zero. This leads to a high reliance on order release accuracy in order to manage production quantities. This paper presents an optimization model that …

From Offshoring To Reshoring: A Conceptual Framework For Manufacturing Location Decisions In A Slow-Steam World, Jeffrey J. Risher

Doctor of Business Administration Dissertations

Reshoring, the act of moving manufacturing operations from an offshore location to the nation of the parent company, is rapidly becoming one of the most researched topics in business. Reshoring describes the reversal of a previous offshoring decision, whereby a firm either relocated its own manufacturing operations overseas or outsourced a significant portion of production to offshore suppliers. With looming uncertainty in global consumer demand and diminishing returns in offshore markets, reshoring is gaining exposure as a viable strategy for firms experiencing a diluted competitive advantage as grounded costs approach market equilibrium.

With academic literature on reshoring only beginning to …

The Use Of Rfid And Sensor Networks To Optimize Enterprise Operations And Logistics, Sobhi Mejjaouli

Theses and Dissertations

One of the biggest challenges faced by today’s supply chain is machine and equipment failures which impacts the producers’ ability to meet their scheduled demand and lead to logistics delays and quality issues, especially when perishable items are transported. This research work eliminates, or at least decreases the costs pertaining to the impact of machine and equipment failures on supply chain operations, particularly on production and transportation, like out of stock costs, lost sales cost and penalties imposed by customers. Two relatively new technologies for the production and logistics domain, RFID and wireless sensor networks, provide the needed sensing, processing, …

Supply Chain Management students from universities around the world travel to Detroit, MI to participate in …

Keys To Successful Balanced Scorecard Implementation And Use Based On Published Implementation Attempts, Aarom J. Hepler, Bradley E. Anderson, Martha C. Cooper, Jeffrey A. Ogden

Journal of Transportation Management

In recent years many companies have evolved from being centrally located and managed to decentralized, multi-national companies consisting of many separate entities to be strategically managed. In response to this and other changes, such as the need for better measurement of performance, a strategic management tool was developed called the Balanced Scorecard (BSC). This research provides a tool to guide and evaluate BSC implementation. A meta-synthesis approach was used to examine qualitative BSC data available in the literature that suggested eleven keys to successful BSC implementation and use. These keys are then used to benchmark an implementation in a government …

Contract-Boundary-Spanning Governance Mechanisms: Conceptualizing Fragmented And Globalized Production As Collectively Governed Entities, Jaakko Salminen

Indiana Journal of Global Legal Studies

Conceptualizing how private actors can and should control their supply chains is a tricky question with both economic and legal dimensions. The topic is of extreme importance in today's global economy. On the one hand, this importance is highlighted by events such as the catastrophic and deadly collapse of the Rana Plaza factory building in Bangladesh and the economic fiasco of the Olkiluoto 3 nuclear power plant construction project in Finland, both arguably caused by the lack of effective supply chain governance. On the other hand, the potential benefits of successful supply chain governance, shown by examples such as open …

An Empirically Derived Framework Of Logistics Management Strategy, Michael A. Mcginnis, Ali Kara, Leslie I. Wolfe

Journal of Transportation Management

The purpose of this paper is to present an empirically derived framework for Logistics Management and discuss how it integrates organization’s short-term objectives with the need to respond to the complex external environment. Organizational theory, strategic planning and logistics management literature were reviewed carefully in identifying the conceptual support for the derived framework of logistics management and organizational competitiveness. The proposed generalized framework demonstrates that Logistics Management Strategy has the strongest positive effect on Organizational Competitiveness when it is mediated by Logistics Coordination Effectiveness and Customer Service Commitment. Overall Logistics Strategy is a necessary, but not sufficient, condition for increased …

Identifying needed skills based on importance is common. Considering more factors than just importance offers a more thorough assessment …

A Study Of The Impact Of Information Blackouts On The Bullwhip Effect Of A Supply Chain Using Discrete-Event Simulations, Elizabeth Rasnick

Information Technology & Decision Sciences Theses & Dissertations

This study adds to the supply chain management literature by introducing and investigating information blackouts, sudden and short-duration failure of the information flow. This study aims to contribute to the literature in following ways: first, to define information blackouts in a supply chain. Second, to investigate the response of supply chains to information blackouts using discrete-event simulation. Prior research has focused more on analyzing systemic disruptions to supply chains from well-known sources. We expect the results of this study to be useful to supply chain managers in disaster prone areas.
