Stern-Gerlach Dynamics With Quantum Propagators, Bailey C. Hsu, Manuel Berrondo, Jean F. Van Huele

Faculty Publications

We study the quantum dynamics of a nonrelativistic neutral particle with spin in inhomogeneous external magnetic fields. We first consider fields with one-dimensional inhomogeneities, both unphysical and physical, and construct the corresponding analytic propagators. We then consider fields with two-dimensional inhomogeneities and develop an appropriate numerical propagation method. We propagate initial states exhibiting different degrees of space localization and various initial spin configurations, including both pure and mixed spin states. We study the evolution of their spin densities and identify characteristic features of spin density dynamics, such as the spatial separation of spin components, and spin localization or accumulation. We …

Drilling For Micro-Foundations Of Human Capital Based Competitive Advantages, Russell Coff, David Kryscynski

Faculty Publications

From the origins of the Resource Based View, scholars have emphasized the importance of human capital as a source of sustained competitive advantage and recently there has been great interest in gaining a better understanding of the micro-foundations of strategic capabilities. Along these lines, there is little doubt that heterogeneous human capital is often a critical underlying mechanism for capabilities. Here, we explore how individual level phenomena underpin isolating mechanisms that sustain human capital-based advantages but also create management dilemmas that must be resolved in order to create value. The solutions to these challenges cannot be found purely in generic …

"Levantine Thinking In Egypt" The Footprint Of Intellectual Influence, Kerry M. Muhlestein

Faculty Publications

Upon examination of material and textual remains, there is a great deal of evidence for more contact with the Levant than many have supposed. This contact took the form of both Eyptians in the Levant and Asiatics in Egypt. Futhermore, the Shipwrecked Sailor bears hallmarks of Levantine literature. This famous tale may thus say something significant about Egyptian/Levantine relations. It seems to attest to intellectual influence flowing into Egypt from the Levant.

Firm Size Matters: An Empirical Investigation Of Organizational Size And Ownership On Sustainability- Related Behaviors, Peter Jack Gallo, Lisa Jones Christensen

Faculty Publications

The phrase “corporate sustainability” is increasingly prevalent in both the industry press and management journals (Engardio, 2007; Montiel, 2008). Corporate sustainability pledges and reports are also increasingly prevalent, yet empirical studies on how top managers define and enact the construct are lacking. To address this deficiency, we investigate how firms define, support, and report their sustainability efforts. In a large sample (N = 922) study of accounting executives at U.S.-based firms, we find evidence that organizational size, ownership, and industry are strongly related with support mechanisms and reporting of sustainability.

Correlation: The Turning Point (1960s), Michael A. Goodman

Faculty Publications

Correlation has a long history of starts and stops, successes and setbacks. Often misconstrued as solely related to curricular issues, correlation has had a much broader focus from the beginning. President Harold B. Lee stated that one of the primary purposes of correlation was to place “the Priesthood as the Lord intended, as the center core of the Kingdom of God, and the auxiliaries as related thereto; including a greater emphasis on the Fathers in the home as Priesthood bearers in strengthening the family unit.”¹

Though the vision has been large as eternity, the work of the kingdom for …

A Petri Net-Based Approach To Reconfigurable Manufacturing Systems Modeling, Y. Geng, A. Lim, H. Ma, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

Reconfigurable manufacturing systems (RMSs) have been used to provide manufacturing companies with the required capacities and capabilities, when needed. Recognizing (1) the importance of dynamic modeling and visualization in decision making support in RMSs and (2) the limitations of the existing studies, we model RMSs based on Petri net (PN) techniques with focus on the process of reconfiguring system elements while considering constraints and system performance. In response to the modeling difficulties identified, a new formalism of colored timed PNs is introduced. In conjunction with colored tokens and timing in colored PNs and timed PNs, we further define a reconfiguration …

Self Assembly In Additive Manufacturing: Opportunities And Obstacles, Nathan B. Crane, J. Tuckerman, G. N. Nielson

Faculty Publications

Purpose

Additive manufacturing offers substantial flexibility in shape, but much less flexibility in materials and functionality—particularly at small size scales. A system for automatically incorporating microscale components would enable the fabrication of objects with more functionality. This paper considers the potential of self assembly to serve as an automated programmable integration method. In particular, it addresses the ability of random self assembly processes to successfully assemble objects with high performance despite the possibility of assembly errors.

Methodology

A self-assembled thermoelectric system is taken as a sample system. The performance expectations for these systems are then predicted using modified one-dimensional models …

The Internationalization Of Singapore’S State Enterprise Network: Notes From Singapore’S Gambits In The Gulf Region, Caroline Yeoh, Wilfred Pow Ngee How

Research Collection Lee Kong Chian School Of Business

The Singapore system of state-led, market interventions and its concerted attempts at creating overseas infrastructural-industrial township projects have received its share of controversies. These state-engineered projects are premised on the exportability of Singapore’s state credibility, systemic and operational efficiencies as well as technological competencies of Singapore companies, government-linked or not, to locations where the attributes are less distinct. This paper, as part of our series on this topic, revisits the city-state’s determined efforts to encapsulate economic space for Singapore-based firms to expand beyond the region, and tests the efficacy of the ‘Singapore system’ exported to foreign locales. This research, however, …

Knowledge Sourcing And Knowledge Consumption In Computer- Mediated Complex Decision Making, Nathan W. Twyman, Jeffrey L. Jenkins, Jay F. Nunamaker Jr., Katherine Carl

Faculty Publications

Individuals are turning increasingly toward web-based information sources as input for complex decisions. Gathering and evaluating decision criteria in an online context is enticing because of information availability and increased control over the process, but how do these factors impact performance? This study shows how an interaction effect between Social Comparison and Social Facilitation predicts and explains how decision making performance is influenced differently by an information consumption-only approach versus a consumeand- contribute approach. Results from an empirical evaluation indicate that publishing decision criteria and reasoning (e.g. in a forum, blog, or knowledge base) plays an important role in improving …

Effects Of Automated And Participative Decision Support In Computer-Aided Credibility Assessment, Matthew L. Jensen, Paul Benjamin Lowry, Jeffrey L. Jenkins

Faculty Publications

Historically, inaccurate credibility assessments have resulted in tremendous costs to businesses and to society. Recent research offers unobtrusive credibility assessment aids as a solution; however, the accuracy of these decision aids is inadequate, and users often resist accepting the aids’ recommendations. We follow the principles of signal detection theory to improve the accuracy of recommendations in computer-aided credibility assessment by combining automated and participatory decision support. We also leverage participation in decision-making theory to explain and predict an increased acceptance of assessment aid recommendations when perceptual cues are elicited from users. Based on these two theories, we design and test …

Model-Driven Software Development, Stephen W. Liddle

Faculty Publications

Software development is a complex and difficult task that requires the investment of significant resources and carries major risk of failure. For decades now, researchers have proposed “model-driven” approaches to improve the state of the art in software engineering. Software models are intended to improve communication among stakeholders and aid in the overall understanding both of a problem space and a proposed software solution that satisfies given requirements. As with architectural blueprints or miniature 3D models, software models make it possible to explore and test a design and its ramifications before investing in the actual build-out. The traditional approach to …

Conceptual-Model Programming: A Manifesto, David W. Embley, Stephen W. Liddle, Óscar Pastor

Faculty Publications

In order to promote conceptual-model programming (CMP), we present these CMP articles. We hold these articles to be the defining principles for model-complete software development.

Essentially, this CMP manifesto asserts that programming activities are to be carried out via conceptual modeling. For applications amenable to conceptual-model designs, software developers should never need to write a line of traditional code. Thus, programming is actually conceptual-model programming.

To accommodate CMP, conceptual-modeling languages must be executable. They must also be capable of completely deploying both databases and user interfaces and conceptually expressing database access and user interaction. To enable CMP, a conceptual-model compiler …

Multilingual Ontologies For Cross-Language Information Extraction And Semantic Search, David W. Embley, Stephen W. Liddle, Deryle W. Lonsdale, Yuri Tijerino

Faculty Publications

Valuable local information is often available on the web, but encoded in a foreign language that non-local users do not understand. Can we create a system to allow a user to query in language L1 for facts in a web page written in language L2? We propose a suite of multilingual extraction ontologies as a solution to this problem. We ground extraction ontologies in each language of interest, and we map both the data and the metadata among the language-specific extraction ontologies. The mappings are through a central, language-agnostic ontology that allows new languages to be added by only having …

Dynamic Collaboration: Participant-Driven Agile Processes For Complex Tasks, Joel H. Helquist, Amit Deokar, Thomas Meservy, John Kruse

Faculty Publications

Groups and decision makers are increasingly running headlong into complexity as interconnections and interdependencies between individuals and organizations continue to grow, decision time horizons shrink and more work is being performed by distributed teams. These factors are driving up overall problem space complexity and limiting the effectiveness of time-tested decision and collaboration processes. Increases in problem space complexity lead to higher equivocality in collaborative processes and associated products. Electronic collaboration support tools and associated process management schemes have proven successful in many challenging contexts. However, current collaboration process management schemes and tools may not be able to effectively handle more …

Picturing Flag Violence In Civil War Sheet Music: The Case Of “Down With The Traitors’ Serpent Flag”, Kenneth Hartvigsen

Faculty Publications

Published in Chicago in 1861, “Down with the Traitors’ Serpent Flag” is one of thousands of political parlor songs from the American Civil War. Many of these songs are unremarkable musically and were preserved in homes, archives, and museum collections largely for their vibrant illustrations. In my presentation I examine this song’s lithographic cover illustration—a Union soldier grinding a Confederate flag into the dust—within a broader discourse of Civil War flag imagery taken from songs, political cartoons, and cartes-de-visite.

Compelling secrets exist within this colorful image that may not first meet the eye; to uncover these meanings along with the …

Review Of Ingres: Painting Reimagined By Susan L. Siegfried, Heather Belnap Jensen

Faculty Publications

Susan L. Siegfried’s Ingres: Painting Reimagined is a magisterial consideration of one of the most intriguing and elusive artists of the nineteenth century, Jean-Auguste-Dominique Ingres. As the summation of a three-decade long engagement with Ingres studies, this ambitious tome sets out to account for the strange and yet beguiling nature of his paintings, c. 1800-1840. In this book, Siegfried argues that the reason Ingres has remained an enigma has much to do with his refusal to produce works that conformed to centuries-old conventions structuring narrative painting. Ingres’s imaginative project, then, was to conceive of innovative strategies for imaging classical tales …

Re-Envisioning Reading And Writing Through Combined-Text Picture Books, Deborah Dean, Sirpa Grierson

Faculty Publications

Combined-text picture books unite multiple genres, providing nuanced information on a single topic from the unique lens of each genre. By providing guided practice in reading and writing a combined-text picture book, teachers can help students develop sensitivity to different types of texts, to what they do and how they do it. Such sensitivity can give students a foundation for selecting appropriate strategies for reading and writing effectively in a wider variety of genres. This article describes the process of explicit instruction, discussion, and guided practice with one such text, One Leaf Rides the Wind, that helped one class …

Shifting Perspectives On Grammar: Changing What And How We Teach, Deborah Dean

Faculty Publications

What is it about teaching language that makes it so problematic? Is it because language is connected to who and what we are and everything we do? That has to be part of it. I know that I’ve been through my share of discussions about language and how to teach it, with those involved holding a variety of perspectives. I’ve watched those discussions shift over the years of my teaching as something new comes up and perspectives shift again. Today, when I read articles or hear discussions about teaching grammar, I find interesting dichotomies in perspectives. Some people see language …

International Entrepreneurship And Capability Development: Qualitative Evidence And Future Research Directions, Erkko Autio, Gerard George, Oliver Alexy

Research Collection Lee Kong Chian School Of Business

In this article, we explore how new capabilities emerge and solidify in new ventures that are faced with fundamental uncertainty from their environment. To do so, we draw from the organizational and entrepreneurial literature on cognition and capabilities. Using initial qualitative evidence from a multi-firm study in the context of new venture internationalization, we develop a cognition-based model of capability emergence in new ventures. Our findings extend the capability development and learning implications of internationalization to the fundamental character of organizing processes in start-ups. Moreover, we derive avenues for future entrepreneurship research on the origins and evolution of capabilities in …

On The Value Relevance Of Retailer Advertising Spending And Same-Store Sales Growth, Kapil Tuli, Anirban Mukherjee, Marnik G. Dekimpe

Research Collection Lee Kong Chian School Of Business

In response to recent calls to study factors that determine a retailer's stock price, this study draws on signaling theory to examine the impact of two key marketing metrics that are widely disclosed by retailers to investors, advertising spending and growth in same-store sales (COMPS), and highlights the moderating role of various firm- and sector-specific factors. Using a stock-response model estimated on a sample of 1,646 observations for 257 retailers, the authors find that the value relevance of advertising spending and COMPS depends on the financial condition of, and the competitive pressures faced by, the retailer. In addition, the positive …

Consolidating Or Non-Consolidating Queues: A Game Theoretic Queuing Model With Holding Costs, Kwan Eng Wee, Ananth Iyer

Research Collection Lee Kong Chian School Of Business

We consider a two-server queueing system in which the servers choose their service rate based on the demand and holding cost allocation scheme offered by the demand generating entity. We provide an optimal holding cost allocation scheme that leads to the maximum possible service rate for each of a pooled and a split system. Our results suggest that careful allocation of holding costs can create incentives that enable minimum turnaround times using a common queue.
