“Go Live In ’05”—From Hierarchy To Shared Governance In Higher Education, Peter A. Maresco

WCBT Faculty Publications

Higher education is in the midst of a major transformation evidenced by several factors: greater demands from stakeholders; pressure to increase student enrollment, financial uncertainty, limited resources, and a responsibility to contribute to the community’s civic and economic development. Faculty and staff in higher education are challenged to deliver education in innovative ways. This innovation requires an expedient method of governance and necessitates careful examination of the organization’s structural, cultural, and decision-making processes. To meet these demands, leaders in higher education must examine decision-making processes and design governance models that respond quickly and efficiently to their myriad of constituents.

Information Systems and Operations Management: Faculty Publications & Other Works

Since the terrorist events in the United States on September 11, 2001, the Federal Motor Carrier Safety Administration has been testing and evaluation cargo tracking technologies to improve the safety, security and efficiency of commercial motor vehicle operations. While satellite-based systems used for tracking vehicles and cargo provide sufficient geographic coverage in the majority of the United States, there remain several vital regions that are uncovered and difficult to monitor. One such region is Alaska, where officials are particularly concerned with the hazardous materials shipments that are transported parallel to the Trans-Alaska Pipeline. This article analyzes the risks and benefits …

Managing Stakeholders During It-Enabled Organizational Transformation: A Case Study Of E-Government In South Korea, Hyun Jeong Kim, Gary Pan, Shan Ling Pan

Research Collection School Of Accountancy

The implementation of e-government is a burgeoning phenomenon across the globe. It improves and enhances the infrastructures and services provided to the citizens. However, a review of the IS literature reveals that research on the implementation of e-government is rather limited, which could be due to the general misconception of the public sectors as rigid and risk-averse establishments. The shortage of studies on e-government’s implementation presents a knowledge gap that needs to be plugged. This gap is significantly amplified by the increasing number of e-government initiatives being implemented by governments in recent years. This paper describes and analyzes South Korea’s …

Will Google And Baidu's Arrival Reshape The Mobile Search Industry In China?, Knowledge@Smu

Knowledge@SMU

China Mobile, China’s largest cell phone carrier, and Google, the world’s largest search engine, announced in January a “mobile search” partnership in China. Nine days later, China Unicom, China’s second-largest cell-phone carrier, reportedly entered into talks with Baidu, the Chinese search engine, about developing a similar alliance in China. The news marked the spread of search-engine warfare from computers to cell phones. For both Baidu and Google, a partnership with mobile operators is expected to help them win a significant number of subscribers in a short period of time. Will Google and Baidu’s arrival reshape the mobile search industry in …

Mike Mccue's Vision For The Convergence Of The Phone And The Web, Knowledge@Smu

Knowledge@SMU

When Mike McCue founded Tellme in 1999, its initial product was a voice-driven information service, what might be termed a "voice portal." Today, the company's voice-recognition systems power directory assistance services from AT&T, Verizon and Cingular along with automated 800-number customer help lines at companies like Merrill Lynch and Federal Express. But McCue still harbors dreams of a broader voice-driven web, one which will provide consumers with new ways of using the phone to interact with the universe of information. He discussed this vision, and others, during a recent interview with Knowledge@Wharton in Tellme's Mountain View, Calif., offices.

Why Software Business Models Of The Future Probably Won't Come In A Box, Knowledge@Smu

Knowledge@SMU

Microsoft's Vista operating system should give the company a revenue stream that will run for years, but experts at Wharton say the January 30 launch of the consumer versions of Microsoft's flagship software may be among the last of its kind -- a product sold for a flat fee in a shrink-wrapped box. Indeed, many wonder if the software business model that has made Microsoft so dominant may begin to fade as new software business models -- from open source to advertising supported -- gain increasing traction.

Make Room, Wikipedia: Internet-Based Collaboration Could Change The Way We Do Business, Knowledge@Smu

Knowledge@SMU

It sounds like something from a futuristic TV thriller: American spies thwarting a terrorist plot through a shared online community modeled after Wikipedia, the free user-created, web-based encyclopedia. But Anthony D. Williams, co-author of the new book, Wikinomics: How Mass Collaboration Changes Everything, recently told a conference at Wharton's Mack Center for Technological Innovation that this online community of spies already exists -- along with a host of other activist-oriented web sites that are changing the rules of the global economy.

Nanofibrous Articles, Gene Kim, Bonnie Bachman, Stephen O. Bozzone

Economics Faculty Research & Creative Works

Nanofibrous articles can be manufactured by a process that includes preparation of a surface of a substrate to provide an adhesion mechanism for securing the nanofibers to the surface. The nanofibers can be dispersed in an area near the substrate for the purpose of being adhered to the surface. If an ordered arrangement of nanofibers is required, an electric field can be provided in the area where the nanofibers are dispersed to selectively control an ordering of the nanofibers as they are adhered to the surface by the adhesion mechanism.

Leading brick-and-mortar retailers such as Best Buy, Circuit City, Target, Gap, …

Enhancing Performance By Salvaging Route Reply Messages In On-Demand Routing Protocols For Manets, Rendong Bai, Mukesh Singhal, Yi Luo

Faculty Research & Creative Activity

Researchers prefer on-demand routing protocols in mobile ad hoc networks where resources such as energy and bandwidth are constrained. In these protocols, a source discovers a route to a destination typically by flooding the entire or a part of the network with a route request (RREQ) message. The destination responds by sending a route reply (RREP) message to the source. The RREP travels hop by hop on the discovered route in the reverse direction or on another route to the source. Sometimes the RREP can not be sent to the intended next hop by an intermediate node due to node …

Who Knew? Admissibility Of Subsequent Remedial Measures When Defendants Are Without Knowledge Of The Injuries, Mark G. Boyko, Ryan G. Vacca

Law Faculty Scholarship

Federal Rule of Evidence 407 prohibits the introduction of subsequent remedial measures for the purposes of demonstrating negligence, culpable conduct, or product defect. But the rule breaks down, in application and purpose, when a defendant undertakes the new safety measure after the plaintiff's injury, but before the defendant had knowledge of the loss. Such a situation is not uncommon. Would-be defendants frequently improve their products and product safety for a variety of reasons. Toxic exposure cases, where exposure often predates diagnosis of the injury by a decade or more, represent a prime example of cases where defendants are likely to …

Expanding Preferential Treatment Under The Record Rental Amendment Beyond The Music Industry, Ryan G. Vacca

Law Faculty Scholarship

In January 2007, the Sixth Circuit Court of Appeals decided Brilliance Audio, Inc. v. Haights Cross Communications, Inc. and answered a lingering question concerning the Copyright Act that had persisted for over twenty years. The court decided whether the protections offered to the music industry under the poorly drafted Record Rental Amendment of 1984 also extended to audiobooks and other non-musical works. This Act deprives owners of items such as tapes and compact discs from renting those items to others without the consent of the copyright owners of the recorded song and the written lyrics and music - a right …

Opportunity Missed: A Brief Look At Entrepreneurship In The U.S. And China, Knowledge@Smu

Knowledge@SMU

The promise or threat of China’s economy has fired the American imagination ever since the first Yankee clipper ship captains voyaged there in the 1780s. Whether perceived as a limitless market for American goods or as an intimidating rival, China is indeed a force to be reckoned with. At first glance, Reed Hundt’s In China’s Shadow is another in a recent spate of books probing the nature of China’s startling rise over the last 30 years. Yet Hundt, former chairman of the FCC during the presidency of Bill Clinton, has written a book whose subtitle is more indicative of his …

Source Code Protection For Applications Written In Microsoft Excel And Google Spreadsheet, Thomas A. Grossman Jr.

Business Analytics and Information Systems

Spreadsheets are used to develop application software that is distributed to users. Unfortunately, the users often have the ability to change the programming statements (“source code”) of the spreadsheet application. This causes a host of problems. By critically examining the suitability of spreadsheet computer programming languages for application development, six “application development features” are identified, with source code protection being the most important. We investigate the status of these features and discuss how they might be implemented in the dominant Microsoft Excel spreadsheet and in the new Google Spreadsheet. Although Google Spreadsheet currently provides no source code control, its web-centric …

Faculty Research & Creative Activity

The focus of the paper is on the analysis of performance effects of different security solutions modeled as aspects in UML. Aspect oriented modeling (AOM) allows software designers to isolate and separately address solutions for crosscutting concerns, which are defined as distinct UML aspect models, then are composed with the primary UML model of the system under development. For performance analysis we use techniques developed previously in the PUMA project, which take as input UML models annotated with the standard UML Profile for Schedulability, Performance and Time (SPT), and transform them first into Core Scenario Model (CSM) and then into …

Employing Intelligent Agents To Automate Sla Creation, Halina Kaminski, Mark Perry

Computer Science Publications

Service Level Agreements (SLAs) are commonly prepared and signed agreements that form the contracts between a service provider and its customers, defining the obligations and liabilities of the parties. Naturally, SLAs should reflect the business needs of both customer and supplier. SLAs are usually formed through either the adoption of a boilerplate agreement from the provider, or through a mediation/negotiation process between the parties. With the increasing adoption of software supply being implemented as a network service, such schemes are rigid or slow and costly, This paper proposes a system that the parties can use to facilitate both fast and …

More Secure Passwords, Scott Magruder, Stanley X. Lewis Jr

Journal of International Technology and Information Management

Passwords are often the first line of defense against hackers trying to logon to a user’s account. Due to this, the password that a user selects for protection of their account is critical. These passwords must be “good” passwords that are not easily cracked. However, how does the network administrator enforce this? A simple change to the login process can make the passwords chosen by users much more secure. A description of this simple process is given in this paper. The normal login process is described. A description of the how hackers attempt to crack passwords is given. The simple …

Improving The Judicial System To Handle Computer Crime, Gerald V. Post, Albert Kagan

Journal of International Technology and Information Management

This paper asked professionals in the legal system to evaluate the current state and effectiveness of laws to identify and deter computer crime. Responses were evaluated with a formal structural equation model. The results generally show that legal professionals believe potential jurors have minimal knowledge of computer crime issues. More importantly, they also believe that judges have little knowledge or experience. A similar lack of knowledge by defense attorneys indicates that it could be difficult for a person accused of computer related infractions to find adequate representation. On the other hand, more experienced participants do not believe computer laws present …

A Framework And Guide For Understanding The Creation Of Consumer Trust, Joseph A. Cazier

Journal of International Technology and Information Management

This paper develops a framework and model for building trust by combining research on the creation of trust with the dimensions of trust: ability, benevolence and integrity. By combining these dimensions in a matrix with the types of trust production based on characteristics, process and institutions, the paper develops a robust 3 x 3 matrix with which to categorize and understand trust production. The framework is developed and analyzed in the light of literature on consumer trust. This framework can help researchers, practitioners and consumers understand trust creation and assist businesses in developing a comprehensive strategy for managing trust.

An Application Of The Deming Management Method For Information Technology Projects, Jack T. Marchewka

Journal of International Technology and Information Management

Although the ideas and teachings of W. Edwards Deming have been implemented in organizations world- wide for over the past 50 years, only three studies have empirically tested a theoretical model grounded in the Deming Management Method. These studies focused on the manufacturing and services area. Today, quality management continues to be an area of interest both in project management and software engineering. The focus of this study is to test the Deming Management Method in information technology (IT) projects. A survey of 63 IT professionals provides empirical support for the Deming Management Method and its application to IT projects. …

Thermal Effectiveness Characteristics Of Low Approach Indirect Evaporative Cooling Systems In Buildings, Ben Costelloe, Donal Finn

Articles

Meteorological enthalpy analysis of temperate and maritime climates above latitude 45°N suggests that the water-side evaporative cooling technique has considerable unrealised potential with contemporary “high temperature” building cooling systems—such as chilled ceilings and displacement ventilation. As low approach conditions are the key to exploiting the cooling potential of the ambient air, thermal performance at such conditions needs to be investigated. To address the research issues, an industrial scale test rig, based on a low approach open cooling tower and plate heat exchanger and designed to maximise evaporative cooling potential, has been constructed. The thermal effectiveness of such systems (as a …
