Tree-Based Algorithm For Stable And Efficient Data Clustering, Hasan Aljabbouli, Abdullah Albizri, Antoine Harfouche Sep 2020

Tree-Based Algorithm For Stable And Efficient Data Clustering, Hasan Aljabbouli, Abdullah Albizri, Antoine Harfouche

Department of Information Management and Business Analytics Faculty Scholarship and Creative Works

The K-means algorithm is a well-known and widely used clustering algorithm due to its simplicity and convergence properties. However, one of the drawbacks of the algorithm is its instability. This paper presents improvements to the K-means algorithm using a K-dimensional tree (Kd-tree) data structure. The proposed Kd-tree is utilized as a data structure to enhance the choice of initial centers of the clusters and to reduce the number of the nearest neighbor searches required by the algorithm. The developed framework also includes an efficient center insertion technique leading to an incremental operation that overcomes the instability problem of the K-means …

How Should We Understand The Digital Economy In Asia? Critical Assessment And Research Agenda, Kai Li, Dan J. Kim, Karl R. Lang, Robert J. Kauffman, Maurizio Naldi

Publications and Research

By Asian digital economy, we refer to high-tech developments, business and social transformations, and information- driven changes in the region’s growth. We discuss its background and foundations, significance in Asia and contribution to removal of historical barriers in traditional business. We assess how new value chains are transforming country-level involvement in worldwide manufacturing and note “smiling curve theory” predictions about the global value chain in Asia for high-tech firms and their economies. The takeaway is that the digital economy in Asian nations involves revamping business processes through technology innovation, government policies for growth, and digital entrepreneurship. We analyze the “digital …

Transshipment Timing In Inventory Competition, Lin Zang Sep 2020

Transshipment Timing In Inventory Competition, Lin Zang

Lingnan Theses (MPhil & PhD)

We study retailers’ preferences for transshipment timing in the presence of product substitution in overlapping markets where there is either pre-substitution transshipment (TS) or post-substitution transshipment (ST). By building a two-retailer game model, we find that when the retailer with excess inventory can dictate the transshipment price, there always exists a unique pair of equilibrium order quantities. We also find that the equilibrium order quantity in the post-substitution transshipment will always be larger than that in the pre-substitution transshipment in the symmetric case. But surprisingly, the expected profit of the post-substitution transshipment always dominates that of the pre-substitution transshipment, though …

Analysis Of Import Changes Through Shift-Share, Location Quotient And Bcg Techniques: Gwangyang Port In Asia, Soo Won Mo, Kwang Bae Lee, Yong Joo Lee, Hong Gyun Park Sep 2020

Analysis Of Import Changes Through Shift-Share, Location Quotient And Bcg Techniques: Gwangyang Port In Asia, Soo Won Mo, Kwang Bae Lee, Yong Joo Lee, Hong Gyun Park

Finance and Supply Chain Faculty Scholarship

The main aim of this article is to analyze the import changes of Gwangyang Port using shift-share, location quotient and BCG matrix techniques. We perform the standard shift-share analysis and spatial shift-share analysis for the period 2010–2018 and investigate the import performance of Gwangyang Port for coal, iron ore, natural gas and vegetable matter. The static analysis shows that the regional shift effect, which is the most important component, is negative for coal and iron ore, but positive for natural gas and vegetable matter. The spatial shift-share analysis also indicates that Gwangyang Port experiences not only the gains in regional …

Aligning Performance Management Systems For Lasting Outcomes In Humanitarian Operations, Kalyn M. Howard Sep 2020

Aligning Performance Management Systems For Lasting Outcomes In Humanitarian Operations, Kalyn M. Howard

Theses and Dissertations

Logistics is dynamic, expansive, and critical to organizational success. While it is generally believed that effective logistics management is associated with positive performance outcomes, the links between organizational practice and performance are understudied. This dissertation leverages resource-based theory and organizational learning theory to examine organizational practice and performance in non-traditional logistics settings, with particular focus on military organizations and humanitarian operational settings. First, a meta-analytical study establishes generalizable associations between various operations management practices and performance outcomes. Then, this is applied to dynamic humanitarian logistics settings, exploring how practitioners perceive practice and performance, and how this is reported and documented …

Customer’S Operational Efficiency And Trade Credit Provision, Wai Ho Chan Aug 2020

Customer’S Operational Efficiency And Trade Credit Provision, Wai Ho Chan

Lingnan Theses (MPhil & PhD)

This study examines whether the trade credit provision is affected by customers’ operational efficiency. We link the supplier firms with their major customers using the Customer Segment database in order to identify the trade credit provision for each pair of supplier-customer relationships. While suppliers have the incentive to provide trade credit to high-quality customers in order to increase market share, excess trade credit would also harm the suppliers once the customers default. Our empirical results indicate that operational efficiency and trade credit are positively associated. This finding supports the view that suppliers tend to select and provide trade credit to …

Management Information Systems Faculty Publications

XYZ Company routinely faced penalties imposed by the United States Internal Revenue Service (IRS) for non-compliance in depositing federal withholding taxes related to the managed benefits plans for its clients.

Factor Market Rivalry, Factor Market Myopia, And Strategic Blind Spots: The Case Of The Truck Driver Labor Market, Stephen A. Lemay, Dave Mcmahon, John Batchelor, Batchelor Keller

Journal of Transportation Management

This article explores the relationships among factor market rivalry, factor market myopia, and strategic blind spots in the context of the labor market for truck drivers. Levitt (1960) developed the concept of market myopia to explain how managers often overlooked key competitors in product markets. Trucking managers might do the same thing in looking at competition for truck drivers. Factor market myopia and strategic blind spots help to explain how this happens, and how it becomes more severe in the context of factor market rivalry. In the trucking industry, factor market myopia and strategic blind spots may mean that managers …

Selected Railroad Contributions To The United States: An Economic And Historical Review, Brian Gurney, Joshua P. Hill

Journal of Transportation Management

Railroads were instrumental in opening the western U.S. in the 19th century. The main incentive provided for the railroads to connect San Francisco, CA and Omaha, NB were land grants out of the public domain. In a period of 21 years (1850-1871), 174 million acres were patented (deeded) primarily to what would become four major railroads. Many acres were returned to the government, some were sold and many others were retained or disposed of through holding companies. This paper emphasizes an oft-overlooked reality: that in many cases the railroads leveraged these land grants in support of the growth and prosperity …
