Technical Opinion: Bosses and Their E-Manners

While hailed for its efficiency in facilitating interactions in an increasingly wired workplace, electronic mail messages (emails) also have a dark side. Pearson and Porath4 noted that the complexity of fast-paced, high tech interactions facilitated by emails fuel incivility as people “believe that they don’t have time to be ‘nice’ and that impersonal modes of […]

Zyzzyva: Speculative Byzantine Fault Tolerance

A longstanding vision in distributed systems is to build reliable systems from unreliable components. An enticing formulation of this vision is Byzantine fault-tolerant (BFT) state machine replication, in which a group of servers collectively act as a correct server even if some of the servers misbehave or malfunction in arbitrary ("Byzantine") ways. Despite this promise, practitioners hesitate to deploy BFT systems at least partly because of the perception that BFT must impose high overheads.

SME Strategies: An Assessment of High vs. Low Performers

Little has been known about how and to what extent small-medium sized enterprises (SMEs) are implementing supply chain management (SCM) initiatives and e-business practices. This article presents some preliminary survey results of relationships between environment, firm strategy and performance. It also discusses the comparative characteristics of strategies and practices between high and low performance SMEs.

Six Strategies For Electronic Medical Records Systems

The health care sector, despite its importance, is still behind most other industries such as retail, manufacturing, and financial services to leverage IT for operational and strategic purposes. Effective development and successful implementation of IT systems are critical in health care as these systems have direct implications for patient safety, mortality, and better quality of life. Here, we discuss several potential drawbacks of current EMR systems and offer six key strategies for development and improvement based on a case study of one of the largest health care providers in the nation—the Veterans Health Administration (VHA).

Conceptually Modeling Windows and Bounds For Space and Time in Database Constraints

A variety of application areas involve spatial and temporal data. Spatial data is used in GIS, logistics, CAD/CAM, robotics and medical imaging to name a few. Systems in financial markets, inventory management, professional sports, consumer research and payroll regularly use historical or temporal data. Within these kinds of systems, spatial and temporal integrity constraints are of key importance. Modeling business rules in traditional applications has strongly been advocated.

Exploring the Dark Side of IS in Achieving Organizational Agility

Organizational agility is currently a popular topic in the academic and practitioner communities. While Information Systems (IS) has been identified as having a positive impact in the pursuit of the goal of the agile organization, we also want to present a set of forces that may act against agility by means of inefficient or ineffective design, use or understanding of the role of IS in the process of acquiring signals, responding and learning from experience.
