A Local Social Network Approach For Research Management, Xiaoyan Liu, Zhiling Guo, Zhenjiang Lin, Jian Ma

Research Collection School Of Computing and Information Systems

Traditional methods to evaluate research performance focus on citation count, quality and quantity of research output by individual researchers. These measures overlook the roles an individual plays in research collaboration, which is critical in an institutional research management environment due to the inherent interdependency among research entities. In order to address the organizational research management needs, we propose a research social network approach to better analyze local collaboration networks. For this purpose, we develop a new “collaboration supportiveness” measure to quantify an individual researcher's collaboration ability. Insights derived from this research are very helpful for managers to effectively allocate resources, …

Collaborative Competitive Intelligence: A Knowledge Base System Approach, Yu Liang Chi, Tsang Yao Chen

Business and Information Technology Faculty Research & Creative Works

This study develops a collaborative decision support system to enhance the enterprise competitive intelligence (CI) decision process. A CI knowledge model is constructed by identifying concepts of and relations among instance types, decision models, rules of thumb, and weighting of organization functions. The system consists of: 1) a Domain Ontology of concepts and instances to express the knowledge categorization structure; 2) a Task Ontology to express an objective-oriented knowledge framework to express the combination of questions; and 3) Semantic Rules to develop the logical steps for problem solving. The case experiment results of high Decision Correctness Rate and Departmental Weighting …

Assessing The Moderating Effect Of Consumer Product Knowledge And Online Shopping Experience On Using Recommedation Agents For Customer Loyalty, Victoria Y. Yoon, R. Eric Hostler, Zhiling Guo, Tor Guimaraes

Research Collection School Of Computing and Information Systems

Social media technologies have greatly facilitated the creation of many types of user-generated information, e.g., product rating information can be used to generate preference-based recommendation. As a decision support tool, a Recommendation Agent (RA) has been widely adopted by many e-commerce websites. The impact of RAs on online shopping has been extensively examined in the IS literature. However, from Marketing and Social Media perspectives, the widely adopted cognitive–affect–conative–action framework of customer loyalty has not been tested in the presence of RAs. Moreover, there has been little research assessing the impact of increasing consumer knowledge about specific product domains on customer …

Capability Deployment In Crisis: Response To Asian Tsunami Disaster, Gary Pan

Research Collection School Of Accountancy

On 26 December 2004, an earthquake occurred under the Indian Ocean, 250 km northwest of the Indonesian island of Sumatra. According to the U.S. geological survey, the magnitude of the earthquake measured 9.0 on the Richter scale and the immense energy released from the earthquake triggered a series of tsunamis traveling at more than 600 km/h. The tsunami devastated the coastline of 13 countries, leaving more than 280,000 people dead and millions homeless. Soon after the disaster, the United Nations and the international community responded quickly with crisis relief operations for the nations affected. Unfortunately, these relief efforts soon ran …

Understanding Online Consumer’S Inter-Purchase Time, Youngsoo Kim

Research Collection School Of Computing and Information Systems

This study is motivated by the premise that online consumers can make a purchase at any time of day if they have even a tiny time slot along with Internet access. Given the increased shopping time flexibility, we first examine the patterns of online purchase timing at an online shopping mall handling diverse products (e.g., Amazon.com). The results show (1) the breakdown of purchase timing regularity and (2) the change of weekly spike purchase occurrence. Second, we build online inter-purchase time and price promotion utilization models and estimate them with the data collected from one of the premier online shopping …

Managerial Incentives And Management Forecast Precision, Qiang Cheng, Ting Luo, Heng Yue

Research Collection School Of Accountancy

Managers have great discretion in determining forecast characteristics, butlittle is known about how managerial incentives affect these characteristics. This paperexamines whether managers strategically choose forecast precision for self-servingpurposes. Building on the prior finding that the market reaction to vague forecasts isweaker than its reaction to precise forecasts, we find that for management forecastsdisclosed before insider sales, more positive (negative) news forecasts are more (less)precise than other management forecasts. The opposite applies to managementforecasts disclosed before insider purchases. These results are consistent withmanagers strategically choosing forecast precision to increase stock prices beforeinsider sales and to decrease stock prices before insider purchases. …

An Investigation Of Decision Analytic Methodologies For Stress Identification, Yong Deng, Chao-Hsien Chu, Huayou Si, Qixun Zhang, Zhonghai Wu

Research Collection School Of Computing and Information Systems

In modern society, more and more people are suffering from some type of stress. Monitoring and timely detecting of stress level will be very valuable for the person to take counter measures. In this paper, we investigate the use of decision analytics methodologies to detect stress. We present a new feature selection method based on the principal component analysis (PCA), compare three feature selection methods, and evaluate five information fusion methods for stress detection. A driving stress data set created by the MIT Media lab is used to evaluate the relative performance of these methods. Our study show that the …

Transforming Finance For The Future, Siu Loon Hoe

Research Collection School Of Computing and Information Systems

Significant changes in external market conditions have resulted in operations placing greater demands on the finance function. Traditional finance departments are increasingly expected to deliver more value and be more proactive in supporting the organization's overall business strategies. Unfortunately, many finance departments are not yet ready to meet such challenges. This article proposes a transformation process to reorganize present day finance functions to become a finance of the future. The proposed process applies tools such as best practices, outsourcing and technology to achieve a desired future outcome.

Incorporating More System-Related Knowledge Into Systems Analysis And Design, Steven Alter

Business Analytics and Information Systems

This paper introduces a new, intuitively straightforward approach for thinking about important aspects of systems that are being analyzed, designed, and constructed. Building on past research highlighting metaphors related to organizations, IS, and projects, it shows how considering common, broadly applicable types of subsystems (not standard IS categories such as MIS and DSS) might provide direction, insight, and useful methods for analysis and design practitioners and researchers. A conceptual model identifies eight types of subsystems that are relevant to most systems in organizations. For each subsystem type, this paper identifies relevant metaphors, concepts, theories, methodologies, success criteria, design tradeoffs, and …

Value Blueprint And Service Design Space For Facilitating Value Creation, Steven Alter

Business Analytics and Information Systems

A new operational perspective on fundamental concepts related to customers, service, and value differs from service-dominant logic in its approach to service systems, value creation, value co-creation, service interactions, value facilitation, and value constellations. This perspective leads to two new tools for supporting service system design: 1) A “value blueprint” uses a swimlane representation to identify where value creation occurs, recognizing that parts of value creation may occur long after service providers have produced their contributions to customer value. 2) A multidimensional design space for value facilitation identifies design dimensions that can be used for characterizing current or proposed approaches …

E-Government Diffusion: Evidence From The Last Decade., Madison Ngafeeson, Mohammad Merhi

Journal Articles

The use of technology to offer goods and services by governments to citizens has been a growing phenomenon in the last decade. Many projects have been recorded across nations in an effort to encourage the adoption and diffusion of e-government. However, these studies have been rather isolated project reports than a com- prehensive global picture. This study examines the e-government diffusion across 192 countries in the last decade. The panel data obtained is analyzed to evaluate the current state of e-government diffusion. Evidence in the last decade suggests that the difference in e-government diffusion is wider from country to country, …

"Big Data" For Business And Education, Shu Z. Schiller

ISSCM Faculty Publications

Have you heard of the phrase, Big Data? The New York Times declared 2012 the dawn of the “Age of Big Data. ”Today, Big Data, together with social and mobile, are the hottest trends in the technology and business communities. "Big Data” is no longer just a technical term, but rather indicates business opportunity. The Data Warehousing Institute (TDWI) Best Practices Report on Big Data Analytics reports that 74% of organizations have adopted some form of analytics today and 34% companies practice some form of advanced Big Data analytics. However, Big Data brings along challenges with benefits. The purpose of …

Platform Regulation On Seller Heterogeneity, Ruhai Wu, Mei Lin

Research Collection School Of Computing and Information Systems

On a "marketplace" platform, where two sides of users trade, the platform owner has an incentive to regulate its marketplace for a higher profit. This study focuses on a monopoly platform's nonpricing, regulatory strategies in governing quality heterogeneity of competing sellers. In contrast to related studies, we endogenize strategic interactions among platform users. Our model extends the circular city model to capture seller heterogeneity in both variety and quality. The closed-form equilibrium solution reveals a ripple effect that exerts competitive pressure from seller to seller at a diminishing magnitude. The equilibrium analysis enables us to connect the economic mechanisms in …

Architectural Control And Value Migration In Layered Ecosystems: The Case Of Open-Source Cloud Management Platforms, Richard Tee, C. Jason Woodard

Research Collection School Of Computing and Information Systems

Our paper focuses on strategic decision making in layered business ecosystems, highlighting the role of cross-layer interactions in shaping choices about product design and platform governance. Based on evidence from the cloud computing ecosystem, we analyze how concerns about architectural control and expectations regarding future value migration influence the design of product interfaces and the degree of openness to external contributions. We draw on qualitative longitudinal data to trace the development of two open-source platforms for managing cloudbased computing resources. We focus in particular on the emergence of a layered "stack" in which these platforms must compete with both vertically …

Enforcing Secure And Privacy-Preserving Information Brokering In Distributed Information Sharing, Fengjun Li, Bo Luo, Peng Liu, Dongwon Lee, Chao-Hsien Chu

Research Collection School Of Computing and Information Systems

Today’s organizations raise an increasing need for information sharing via on-demand access. Information brokering systems (IBSs) have been proposed to connect large-scale loosely federated data sources via a brokering overlay, in which the brokers make routing decisions to direct client queries to the requested data servers. Many existing IBSs assume that brokers are trusted and thus only adopt server-side access control for data confidentiality. However, privacy of data location and data consumer can still be inferred from metadata (such as query and access control rules) exchanged within the IBS, but little attention has been put on its protection. In this …

Social Media Assimilation In Firms: Investigating The Roles Of Absorptive Capacity And Institutional Pressures, Pratyush Bharati, Chen Zhang, Abhijit Chaudhury

Management Science and Information Systems Faculty Publication Series

Firms are increasingly employing social media to manage relationships with partner organizations, yet the role of institutional pressures in social media assimilation has not been studied. We investigate social media assimilation in firms using a model that combines the two theoretical streams of IT adoption: organizational innovation and institutional theory. The study uses a composite view of absorptive capacity that includes both previous experience with similar technology and the general ability to learn and exploit new technologies. We find that institutional pressures are an important antecedent to absorptive capacity, an important measure of organizational learning capability. The paper augments theory …

Towards Operations Excellence: Optimising Staff Scheduling For New Emergency Department, Amr Arisha, Waleed Abo Hamad

Conference papers

This paper presents a case study of an Emergency Department of a public hospital in Dublin, and uses an integrated approach to determine optimal staffing levels to meet the challenges of its dynamic patient demand levels. A comprehensive stochastic model is developed to incorporate patients care pathways and the resources required along their treatment journeys. Analytical Hierarchical Process is utilised to enable decision makers to set their preferences for the facility’s strategic objectives. Evolutionary algorithms are applied to optimise staff schedules. The resulted optimized schedules maintains continuity of care delivery for patients while ensuring a balanced equilibrium among available staff.

Design Capital And Design Moves: The Logic Of Digital Business Strategy, C. Jason Woodard, Narayan Ramasubbu, F. Ted Tschang, V. Sambamurthy

Research Collection Lee Kong Chian School Of Business

As information technology becomes integral to the products and services in a growing range of industries, there has been a corresponding surge of interest in understanding how firms can effectively formulate and execute digital business strategies. This fusion of IT within the business environment gives rise to a strategic tension between investing in digital artifacts for long-term value creation and exploiting them for short-term value appropriation. Further, relentless innovation and competitive pressures dictate that firms continually adapt these artifacts to changing market and technological conditions, but sustained profitability requires scalable architectures that can serve a large customer base and stable …

Examining The Impact Of Information Technology On Healthcare Performance: A Theory Of Swift And Even Flow (Tsef) Perspective, Sarv Devaraj, Terence T. Ow, Rajiv Kohli

Management Faculty Research and Publications

The impact of information technologies on manufacturing operations and performance is well established. However, scant research has been devoted to examining information technology (IT) investment among hospitals and how it influences patient care and financial performance. Using the lens of the Theory of Swift Even Flow (TSEF), we present an operations management-based perspective on the effect of IT in streamlining hospital operations. Specifically, we examined the role of IT on patient flow and its consequences for improved hospital efficiency and performance. Analysis of data from 567 U.S. hospitals shows that IT is associated with swift and even patient flow, which …

The Cio: Defining A Career For The Future, Mark Askren

Information Technology Services: Publications

Those of us who are IT professionals in higher education spend a lot of our time focused on the “new normal” of accelerating demand, flat resources, and constant change. But we often invest little time in assessing and advancing our careers. As a community, we are typically self-motivated to reach our potential and, in many cases, to extend the boundaries of our potential. However, if we are laissez-faire in our approach to career growth—in other words, if we are “too busy” to focus on ourselves—reaching our potential becomes much less likely.

In 2013, information technology matters . . . a …

Churn Management Optimization With Controllable Marketing Variables And Associated Management Costs, Yong Seog Kim, Hyeson Lee, John D. Johnson

Data Analytics & Information Systems Faculty Publications

In this paper, we propose a churn management model based on a partial least square (PLS) optimization method that explicitly considers the management costs of controllable marketing variables for a success- ful churn management program. A PLS prediction model is first calibrated to estimate the churn proba- bilities of customers. Then this PLS prediction model is transformed into a control model after relative management costs of controllable marketing variables are estimated through a triangulation method. Finally, a PLS optimization model with marketing objectives and constraints are specified and solved via a sequential quadratic programming method. In our experiments, we observe …

The Influence Of Enterprise Systems On Business And Information Technology, D. Lance Revenaugh, Ph.D., Myles M. Muretta

Business & Information Technology

Business strategy is important to all organizations. Nearly all Fortune 500 firms are implementing Enterprise Resource Planning (ERP) systems to improve the execution of their business strategy and to improve integration with its information technology (IT) strategy. Successful implementation of these multi-million dollar software systems are requiring new emphasis on change management and on Business and IT strategic alignment. This paper examines business and IT strategic alignment and seeks to explore whether an ERP implementation can drive business process reengineering and business and IT strategic alignment. An overview of business strategy and strategic alignment are followed by an analysis of …

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

MIS/OM/DS Faculty Publications

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.

The Effect Of Crm Outsourcing On Shareholder Value: A Contingency Perspective, Kalaignanam Kartik, Tarun Kushwaha, Jan-Benedict E. M. Steenkamp, Kapil R. Tuli

Research Collection Lee Kong Chian School Of Business

CRM refers to processes that involve interaction with end-users or customers. The increased emphasis on CRM today stems from changes in the business environment, availability of large amounts of data and advances in information technology.Outsourcing of customer relationship management (CRM) processes is rapidly becoming a competitive imperative for firms. However, there is little evidence on why the performance implications of outsourcing CRM processes differ so much across firms. In this study, the authors examine the impact of CRM outsourcing on shareholder value. The authors draw on insights from agency theory and the resource-based view of the firm in an international …

Work System Theory: Overview Of Core Concepts, Extensions, And Challenges For The Future, Steven Alter

Business Analytics and Information Systems

This paper presents a current, accessible, and overarching view of work system theory. WST is the core of an integrated body of theory that emerged from a long-term research project to develop a systems analysis and design method for business professionals called the work system method (WSM). After discussing WST’s basic premises and its two central frameworks, this paper summarizes the relationship between WST and WSM. It shows how experience with early versions of WSM led to three extensions of WST that addressed limitations-in-use in one of the central frameworks in WST. After comparisons with related theories, this paper closes …

Enabling Greater Access To Home Meal Delivery, Maciek Nowak, Leo Gala, Mike Hewitt

Information Systems and Operations Management: Faculty Publications & Other Works

Non-profit organizations like the Meals on Wheels (MOW) association of America prepare and deliver meals, typically daily, to approximately one million homebound citizens in the United States alone. However, many MOW agencies are facing a steadily increasing number of clients requesting meal service without an increase in resources (either financial or human). One strategy for accommodating these requests is to deliver multiple (frozen) meals at a time and thus make fewer delivers. However, many of the stakeholders (funders, volunteers, meal recipients) value the relationships that are developed by having a client receive daily deliveries from the same volunteer. Further, meal …

Online Course Evaluations Response Rates, Faruk Guder, Mary Malliaris

Information Systems and Operations Management: Faculty Publications & Other Works

This paper studies the reasons for low response rates in online evaluations. Survey data are collected from the students to understand factors that might affect student participation in the course evaluation process. When course evaluations were opened to the student body, an email announcement was sent to all students, and a reminder email was sent a week later. Our study showed that participation rates increased not only when emails were sent, but also when faculty used in-class time to emphasize the importance of completing the evaluations.
