Merger simulations focus on the price changes that may occur once previously independent competitors set prices jointly and other market participants respond. This paper considers an additional effect – the possibility that market participants choose to change their product offerings after a merger. Using a model that endogenizes both product choice and pricing, we conduct equilibrium market si...

Over the past two years a combination of circumstances has fueled intense efforts to rethink the integration of IP networking and mass storage. Chief among these facts are the universal acceptance of Internet technologies for network infrastructure, the relentless acceleration of the Ethernet substrate, and the ongoing, exponential rise in the amount of data that must be moved and managed. Take...

Machine involvement has the potential to speed up language documentation. We assess this potential with timed annotation experiments that consider annotator expertise, example selection methods, and suggestions from a machine classifier. We find that better example selection and label suggestions improve efficiency, but effectiveness depends strongly on annotator expertise. Our expert performed...

Operators are adopting end-to-end Service Delivery Platforms (SDPs) to increase service revenue growth and retain customers. They require these additional SDP enablers to achieve efficient service lifecycle management. Rapid rollout, operation and retirement of services are necessary to optimise service revenues. Historical operator experiences clearly highlight the significant risks associated...

This paper examines the effect of geographic and industrial diversification on firm value for a sample of 1,914 corporations from 18 countries. Our results indicate that both geographic and product diversification destroy value at high levels of diversification, suggesting that agency and influence costs arising from the increased complexity outweigh the benefits of diversification at high degr...

This paper reflects the results of phase I of our study on the total cost of ownership (TCO) of open source software adoption. Not only have we found TCO to be an intriguing issue but it is contentious, baffling and each company approaches it in a distinctive manner (and sometimes not at all). In effect it is a conundrum that needs unpacking before it can be explained and understood. Our paper ...

T he idea of green high-performance computing (HPC) has been gaining traction over the past fi ve years. In November 2008, the Green 500 list (www.green500.org) was introduced to “raise awareness about power consumption, promote alternative total cost of ownership performance metrics, and ensure that supercomputers only simulate climate change and not create it.” The Green 500 lists the world’s...

T he U.S. government reports on minority business ownership as part of the regular economic census performed every 5 years in years ending in 2 or 7. For the purposes of this census, minority-owned businesses are all those not owned by nonminority (Caucasian) business owners. By this definition, minority-owned businesses make up approximately 15% of all U.S. firms. Between 1992 and 1997, minori...

“Cloud” computing – a relatively recent term, builds on decades of research in virtualization, distributed computing, utility computing, and more recently networking, web and software services. It implies a service oriented architecture, reduced information technology overhead for the end user, great flexibility, reduced total cost of ownership, on demand services and many other things. This pa...

Constrained Application Protocol (CoAP) has been introduced as a simpler alternative to the Hypertext Transfer Protocol (HTTP) for connecting constrained smart objects to the Web. The adoption of the protocol depends on its relative advantage, and the cost-benefit associated with the use of the protocol is a significant factor affecting a protocol adoption decision. This paper aims at deepening...
