Owner-Manager Separation And The Structure Of It Governance In Small Business, Jeffrey S. Saffer

Walden Dissertations and Doctoral Studies

Small business owners and small business managers tend to favor different information technology (IT) governance structures. Such differences can lead to ineffective management and control of IT in small businesses. The purpose of this correlational study was to examine the extent and nature of the association between owner-manager separation in small businesses and the structure of IT governance in the businesses. Agency theory formed the theoretical framework of this study. Data were collected using a web-based survey and randomly sampled 3,697 small business owners and managers located in New Jersey and Pennsylvania. Chi-square statistics indicated no significant association between owner-manager …

Two Stage Procurement Processes With Competitive Suppliers And Uncertain Supplier Quality, Yue Jin, Jennifer K. Ryan, Walter Yund

Department of Supply Chain Management and Analytics: Faculty Publications

This paper considers a sourcing problem faced by a manufacturer who outsources the manufacturing of a product to one of several competing suppliers, whose cost and quality capabilities are unknown. We consider a two-stage sourcing process in which the first stage is the qualification stage, while the second stage is the supplier selection stage. In the first stage, the manufacturer exerts effort to learn about the quality level of each of the suppliers and then must determine the set of qualified suppliers, subject to some tolerance for error. In the second stage, the manufacturer runs a price-only procurement auction, in …

A Quality Approach To Tacit Knowledge Capture: Effective Practice To Achieving Operational Excellence, William G. Dzekashu, Walter R. Mccollum Phd

International Journal of Applied Management and Technology

Knowledge loss resulting from an aging workforce continues to be a management nightmare that has obliged many organizational leaders to develop strategies aimed at documenting mission-critical knowledge. Yet knowledge captured and stored in repositories continues to lack quality. The purpose of this study was to explore the impact of integrating quality management into the tacit knowledge capture process. Further studies on the effects of personality in the knowledge capture processes could lead to insights on reasons for diminished knowledge quality. From a social perspective, the implementation of a model that encompasses personality and quality management could improve decision-making processes.

A Federated Architecture For Heuristics Packet Filtering In Cloud Networks, Ibrahim M. Waziri Jr

College of Graduate Studies: Theses & Dissertations

The rapid expansion in networking has provided tremendous opportunities to access an unparalleled amount of information. Everyone connects to a network to gain access and to share this information. However when someone connects to a public network, his private network and information becomes vulnerable to hackers and all kinds of security threats. Today, all networks needs to be secured, and one of the best security policies is firewall implementation.

Firewalls can be hardware or cloud based. Hardware based firewalls offer the advantage of faster response time, whereas cloud based firewalls are more flexible. In reality the best form of firewall …

However, what has not been well understood are the characteristics of competent IS users who are proficient in using IS and are able to achieve quality IS usage. Considering that improving IS users' abilities to more efficiently and effectively use IS has always been and remains a challenge, research that provides a comprehensive view of the characteristics associated with competent IS users is warranted. This paper addresses this research question by proposing a conceptual foundation for IS user competency. Based …

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, …

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 …

Data Mining The Harness Track And Predicting Outcomes, Robert P. Schumaker

Journal of International Technology and Information Management

This paper presented the S&C Racing system that uses Support Vector Regression (SVR) to predict harness race finishes and analyzed it on fifteen months of data from Northfield Park. We found that our system outperforms the most common betting strategies of wagering on the favorites and the mathematical arbitrage Dr. Z system in five of the seven wager types tested. This work would suggest that an informational inequality exists within the harness racing market that is not apparent to domain experts.

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 …

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.

Managing Inventory In Global Supply Chains Facing Port-Of-Entry Disruption Risks, Alan Erera, Maciek Nowak, Chelsea White

Information Systems and Operations Management: Faculty Publications & Other Works

Ports-of-entry are critical components of the modern international supply chain infrastructure, particularly container seaports and airfreight hubs. The potential operational and economic impact resulting from their temporary closure is unknown, but is widely believed to be very significant. This paper investigates one aspect of this potential impact, focusing specifically on the use of supply chain inventory as a risk mitigation strategy for a one supplier, one customer system in which goods are transported through a port-of-entry subject to temporary closures. Closure likelihood and duration are modeled using a completely observed, exogenous Markov chain. Order lead times are dependent on the …

Modeling Social Transmission Dynamics Of Unhealthy Behaviors For Evaluating Prevention And Treatment Interventions On Childhood Obesity, Leah M. Frerichs, Ozgur M. Araz, Terry T.-K. Huang

Department of Supply Chain Management and Analytics: Faculty Publications

Research evidence indicates that obesity has spread through social networks, but lever points for interventions based on overlapping networks are not well studied. The objective of our research was to construct and parameterize a system dynamics model of the social transmission of behaviors through adult and youth influence in order to explore hypotheses and identify plausible lever points for future childhood obesity intervention research. Our objectives were: (1) to assess the sensitivity of childhood overweight and obesity prevalence to peer and adult social transmission rates, and (2) to test the effect of combinations of prevention and treatment interventions on the …

The It-Business Equilibrium Model: Understanding The Dynamics Between Business Demand And It Supply, Lawrence Ness, Shankar Babu Chebrolu

International Journal of Applied Management and Technology

The factors that could be used to define, measure, and improve IT flexibility are not considered to be well-defined or understood. A theoretical framework for understanding and determining such factors is proposed in this article, which could be used by business and IT leaders to assess their IT flexibility. Organizations can use this framework, termed the IT-business equilibrium model, as a tool to improve their own IT flexibility as a means to improve their IT effectiveness and ultimately achieve sustained competitive advantage for their businesses.

Coordinating A Supply Chain With A Manufacturer-Owned Online Channel: A Dual Channel Model Under Price Competition, Jennifer K. Ryan, Daewon Sun, Xuying Zhao

Department of Supply Chain Management and Analytics: Faculty Publications

We consider a dual channel supply chain in which a manufacturer sells a single product to end-users through both a traditional retail channel and a manufacturer-owned direct online channel. We adopt a commonly used linear demand substitution model in which the mean demand in each channel is a function of the prices in each channel.We model each channel as a news vendor problem, with price and order quantity as decision variables. In addition, the manufacturer must choose the wholesale price to charge to the independent retailer. We analyze the optimal decisions for each channel and prove the existence of a …

This paper explores the implementation of a Customer Relationship Management (CRM) system to support external engagement and to build business intelligence in one higher education institution in Ireland. Building on the findings of the Roadmap for Employment-Academic Partnership (REAP) project, through a structured process towards a professional case management approach to interactions this project focuses on the introduction of a …

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 …

Workforce Management In Periodic Delivery Operations, Karen Smilowitz, Maciek Nowak, Tingting Jiang

Information Systems and Operations Management: Faculty Publications & Other Works

Service quality and driver efficiency in the delivery industry may be enhanced by increasing the regularity with which a driver visits the same set of customers. However, effectively managing a workforce of drivers may increase travel distance, a traditional metric of the vehicle routing problem (VRP). This paper evaluates the effect that workforce management has on routing costs, providing insight for managerial decision making. The analysis is presented in the context of the period vehicle routing problem (PVRP), an extension of the VRP with vehicle routes constructed to service customers according to preset visit frequencies over an established period of …

Technology Investment Decision-Making Under Uncertainty: The Case Of Mobile Payment Systems, Robert J. Kauffman, Jun Liu, Dan Ma

Research Collection School Of Computing and Information Systems

The recent launch of Google Wallet has brought the issue of technology solutions in mobile payments (m-payments) to the forefront. In deciding whether and when to adopt m-payments, senior managers in banks are concerned about uncertainties regarding future market conditions, technology standards, and consumer and merchant responses, especially their willingness to adopt. This study applies economic theory and modeling for decision-making under uncertainty to bank investments in m-payment systems technology. We assess the projected benefits and costs of investment as a continuous-time stochastic process to determine optimal investment timing. We find that the value of waiting to adopt jumps when …

Agent-Based Virtual Humans In Co-Space: An Evaluative Study, Yilin Kang, Ah Hwee Tan, Fiona Fui-Hoon Nah

Business and Information Technology Faculty Research & Creative Works

Co-Space refers to interactive virtual environment modelled after the real world in terms of look-and-feel, functionalities and services. We have developed a 3D virtual world named Nan yang Technological University (NTU) Co-Space populated with virtual human characters. Three key requirements of realistic virtual humans in the virtual world have been identified, namely (1) autonomy: Agents can function on their own, (2) interactivity: Agents can interact naturally with players, and (3) personality: Agents can exhibit human traits and characteristics. Working towards these challenges, we propose a brain-inspired agent architecture that integrates goal-directed autonomy, natural language interaction and human-like personality. We conducted …

Meaningful Use And Meaningful Curricula: A Survey Of Health Informatics Programs In The U.S., Kai Koong, Madison Ngafeeson, Lai Lui

Journal Articles

The introduction of the US government’s Meaningful Use criteria carries with it many implications including the training curriculum of healthcare personnel. This study examines 108 health informatics degree programmes across the USA. First, the courses offered are identified and classified into generic classes. Next, these generic groupings are mapped to two important frameworks: the Learning to Manage Health Information (LMHI) academic framework; and the Meaningful Use criteria policy framework. Results suggest that while current curricula seemed acceptable in addressing Meaningful Use Stage 1 objective, there was insufficient evidence that these curricula could support Meaningful Use Stage 2 and …

It is yet unclear which component(s) of organization play the prominent role(s) in organizational readiness to adopt emerging technologies. Using a mixed method, this study conducted an online survey of 83 South African organizations for server virtualization adoption. Server virtualization is an emerging technology being widely adopted in most organizations in developed countries. IT executives rated server virtualization as the second-most important technology to help achieve cost reductions and optimize productivity in recent surveys. Very …

F.A.C.E.S. (Faculty Academic Community Education Showcase): Professional Growth Experiences In A Career University, Paul J. Colbert, Ph.D.

MBA Faculty Conference Papers & Journal Articles

Institutes of higher education exist for the purpose of developing, fostering, nurturing, and stimulating the intellectual growth and development of students. The core values of a college education provide students conceptual and practical educational opportunities that focus on improving their skills and knowledge. These skills and knowledge translate into purposeful, real-life learning experiences. However, in the academic community, learning is not restricted to students. Faculty, too, must be supported and provided opportunities for personal and professional growth and development. Although professional development is not a novel concept in the education profession, schools often take up the gauntlet, but fall short …

The success of many different kinds of e-business operations depends on data and information, and how they are used to optimize operations, drive sales and marketing, and grow the business. The ability to manage and safeguard data as a strategic asset, transform it into actionable information, and use it as a strategic differentiator is a key contributor to the success of any business operation. What makes this an even more interesting challenge is the speed at which data have been growing in recent years, due to social networking, the Internet, mobile telephony and all kinds of new technologies that create …

Long Live Design Science Research! .... And Remind Me Again About Whether It Is A New Research Paradigm Or A Rationale Of Last Resort For Worthwhile Research That Doesn't Fit Under Any Other Umbrella, Steven Alter

Business Analytics and Information Systems

There is broadening and increasingly unquestioned acceptance of design science research (DSR). Recently, DSR may have provided an important bridge for overcoming or bypassing artificial barriers to accepting the legitimacy of certain types of research, but in some cases it is not obvious how DSR actually contributed to the research. Perhaps it is time to retire the assumption that DSR is somehow a new and different paradigm for doing research and to move on. Recognizing that the information-systems discipline is quintessentially rooted in design, this panel examines whether we actually need DSR to legitimize research that produces interesting and valuable …
