Shipment Sizing For Autonomous Trucks Of Road Freight, Chun-Miin (Jimmy) Chen, Yajun Lu

Faculty Journal Articles

Unprecedented endeavors have been made to take autonomous trucks to the open road. This study aims to provide relevant information on autonomous truck technology and to help logistics managers gain insight into assessing optimal shipment sizes for autonomous trucks. Empirical data of estimated autonomous truck costs is collected to help revise classic, conceptual models of assessing optimal shipment sizes. Numerical experiments are conducted to illustrate the optimal shipment size when varying the autonomous truck technology cost and transportation lead time reduction. Autonomous truck technology can cost as much as 70% of the price of a truck. Logistics managers using classic …

Contracting Mechanisms For Stable Sourcing Networks, Jennifer K. Ryan, Lusheng Shao, Daewon Sun

Department of Supply Chain Management and Analytics: Faculty Publications

Problem definition: We study profit allocation for a sourcing network, in which a buyer sources froma set of differentiated suppliers with limited capacity under uncertain demand for the final product. Whereas the buyer takes the lead in forming the sourcing network and designing the contract mechanism, due to their substantial bargaining power, the suppliers take the lead in determining the terms of the contract. Academic/practical relevance: We identify contracting mechanisms that will ensure the stability of the sourcing network in the long term, where a stable sourcing network requires an effective profitallocation scheme that motivates all members to …

Assessing Topical Homogeneity With Word Embedding And Distance Matrices, Jeffrey M. Stanton, Yisi Sang

School of Information Studies - Faculty Scholarship

Researchers from many fields have used statistical tools to make sense of large bodies of text. Many tools support quantitative analysis of documents within a corpus, but relatively few studies have examined statistical characteristics of whole corpora. Statistical summaries of whole corpora and comparisons between corpora have potential application in the analysis of topically organized applications such social media platforms. In this study, we created matrix representations of several corpora and examined several statistical tests to make comparisons between pairs of corpora with respect to the topical homogeneity of documents within each corpus. Results of three experiments suggested that a …

Bear River Health Department: Covid-19 Contact Tracing, Mike Dixon, Zach Rusk

Huntsman School of Business Teaching Scholarship Series

This case introduces students to a highly variable process that has uncertain demand and processing times. It describes the contact tracing efforts as a response to positive Covid-19 cases in a rural health district in the state of Utah during the first 9 months of the pandemic of 2020. The case puts students in the shoes of the managing director of a health department trying to decide how to best manage a team of contact tracers who are increasingly unable to timely complete their work that is vital to stopping the spread of the disease.

Human Flourishing And The Subjective Dimension Of Work, Geoffrey Friesen

Department of Finance: Faculty Publications

This essay considers the Christian understanding of the subjective dimension of human work and the implications for economics, finance, and the modern firm. The biblical account of people profoundly captures the fullness of human nature and the role of work and economy in developing the full person. People’s reality is both individual and collective, encompassing their subjective interior and objective exterior dimensions of reality. This issue is important because economic models affect economic decisions, and these decisions help shape social reality. Current economic and financial models are problematic because they are self-limiting: They close off certain outcomes by assuming they …

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 …

Predicting Attrition - A Driver For Creating Value, Realizing Strategy, And Refining Key Hr Processes, Kevin Mendonsa, Maureen Stolberg, Vivek Viswanathan, Scott Crum

SMU Data Science Review

Talent is the most important asset for every organization's success. While attrition (or churn) and turnover can refer to both employees and customers, this paper will focus on employee attrition only. Many organizations accept attrition as an inevitable cost of doing business and do nothing to adopt or implement mitigating strategies to combat it. World class companies on the other hand take deliberate measures to understand, control and mitigate attrition (turnover) at every stage. Unmitigated attrition can have a devastating effect on an organization's bottom line and market value. In addition, the “invisible" costs of low employee morale, reduced employee …

The Effects Of Covid-19 Preoccupation On Business Activity: A Bounded Rationality Perspective, James White

Undergraduate Honors Theses

Using the unique conditions afforded by the global pandemic, we examine Simon’s influential 1947 Bounded-rationality theory with empirical data. We attempt to correlate a shift in attention with a decrease in routine organizational activity. Using a relative measure for interest in COVID-19 topic prevalence from Google Trends and sales activity from a diverse sample of business to business companies. Our results support Simon’s theory. We found a moderate relationship between routine activity and a global shift in attention. Furthermore, the data highlight a possible theoretical threshold necessary for an event to cause divergence.

Three Essays On Ceo Activism, Strategic Choices And Firm Performance, Keshab Acharya

Theses and Dissertations

There is a longstanding societal expectation that business leaders refrain from involving in social and political issues and primarily focus on managing their firms. In recent years, however, there is a growing trend of CEOs taking a stance on controversial sociopolitical issues that are not directly related to their company’s core business. This dissertation consists of three essays focusing on this phenomenon of CEO activism.

In my first essay, given that CEO activism represents a nascent phenomenon, I explore the conceptualization of CEO activism. Additionally, I propose three main motives behind CEO activism: intrinsic, instrumental, and stakeholder-focused. In my second …

Seeking A Perfect Match: The Effect Of Spousal Capital On Performance Of Family Firms, Xi Yang

Theses and Dissertations

The research about family business has received increasing attention. However, the research that focuses on the effect of owner-managers marriage on family firm performance is scarce. In this study, I argue that the family business manager's spouse can affect firm performance through firm-level and individual-level channels. First, I propose that a family business's firm performance is influenced by owner-managers marriage in terms of spousal human, social, and financial capital based on a family capital topology—a firm-level lens. I build a conceptual model of spousal capital in a family business and develop hypotheses. Further, by integrating the complementary needs theory of …

Two Sides Of The Same Coin: Essays Investigating The Founder And Backer Dynamics Of Crowdfunding, Ruben Ceballos

Theses and Dissertations

Crowdfunding provides the opportunity for entrepreneurs to acquire capital for their projects by utilizing a platform that allows the masses to provide funds towards the completion of the project. Thus, it can be looked at as two sides of the same coin. On one side you have the entrepreneurs seeking the funds otherwise known as founders, and on the other are those that provide the funds also known as backers. The purpose of this study is to investigate what factors lead to founders successfully attaining their funding, what motivates backers to support the projects, and whether the founders can deliver …

Busy Directors And The Occurrence Of Corporate Environmental Misconduct, Michael A. Abebe, Carla D. Jones, Keshab Acharya

Management Faculty Publications

The occurrence of corporate misconduct is a significant organizational event that adversely affects not only the firm’s performance but also its relationships with key stakeholders. Corporate directors are pivotal in the prevention and management of organizational misconduct. In this study, we focus on the phenomenon of “overboarded directors” (those serving on three or more corporate boards). Specifically, we propose that busy directors are less likely to be effective in monitoring environmental misconduct given the substantial cognitive overload and a limited sense of alertness associated with multiple directorships. We propose that firms with busy directors are more likely to have environmental …

Unpacking Burt’S Constraint Measure, Martin G. Everett, Stephen P. Borgatti

Management Faculty Publications

Burt (1992) proposed two principal measures of structural holes, effective size and constraint. However, the formulas describing the measures are somewhat opaque and have led to a certain amount of confusion. Borgatti (1997) showed that, for binary data, the effective size formula could be written very simply as degree (ego network size) minus average degree of alters within the ego network. The present paper presents an analogous reformulation of the constraint measure. We also derive minima and maxima for constraint, showing that, for small ego networks, constraint can be larger than one, and for larger ego networks, constraint cannot get …

Metacritiques Of Upper Echelons Theory: Verdicts And Recommendations For Future Research, Brett H. Neely Jr., Jeffrey B. Lovelace, Amanda P. Cowen, Nathan J. Hiller

Department of Management: Faculty Publications

After more than 35 years, Hambrick and Mason’s upper echelons theory (UET) stands as one of the most influential perspectives in management research. However, as the literature and its attendant reviews have become more numerous and specialized, discussion of the fundamental conceptual and methodological critiques leveled against research utilizing the UET perspective has grown fragmented. As such, the first aim of the present review is to identify and synthesize a set of common critiques levied against UET research. In doing so, we unpack important nuance within each critique while establishing a common vocabulary to facilitate greater consistency in how these …

A Review Study Of Functional Autoregressive Models With Application To Energy Forecasting, Ying Chen, Thorsten Koch, Kian Guan Lim, Xiaofei Xu, Nazgul Zakiyeva

Research Collection Lee Kong Chian School Of Business

In this data‐rich era, it is essential to develop advanced techniques to analyze and understand large amounts of data and extract the underlying information in a flexible way. We provide a review study on the state‐of‐the‐art statistical time series models for univariate and multivariate functional data with serial dependence. In particular, we review functional autoregressive (FAR) models and their variations under different scenarios. The models include the classic FAR model under stationarity; the FARX and pFAR model dealing with multiple exogenous functional variables and large‐scale mixed‐type exogenous variables; the vector FAR model and common functional principal component technique to handle …

Work In Progress: Students' Perception Of Collaborative Online International Learning, Philip Appiah-Kubi, Jennifer Nichwitz

Engineering Management and Systems Faculty Publications

Teaching and learning in the digital age harness the opportunities created by internet technologies to distribute and learn various information all over the world. This is commonly referred to as connectivism, and it values the impact of stakeholder information appraisal skills, virtual and personal communication skills [1], and the sense of cultural awareness. Collaborative Online International Learning (COIL), a type of connectivism, typically involves instructors and students from at least two geographically and culturally distinct areas who collaborate virtually on a common project for four or more weeks.

The objective is to create a culturally diverse virtual environment where students …

How Does Your Garden Grow? The Interface Of Employee And Sales Growth Post Ipo, Varkey K. Titus Jr., Jenna R. Pieper, Matthew Josefy, Theresa M. Welbourne

Department of Management: Faculty Publications

Research Summary: Firms often succumb to a growth imperative, yet little is known about how congruence between various forms of growth affects firm value. We argue that the (in)congruence between net hiring rates (e.g., growth in the number of employees) and sales growth has significant implications for firm value, assessed via Tobin's Q. We further contend that R&D expenditures and industry dynamism—factors that influence a firm's ability to realize value creation—moderate the relationship between growth pattern and firm value. We use a sample of 1,181 firms that conducted their initial public offerings from 1996 to 2006 to test our conceptual …
