Virtualization is the simulation or emulation of computer resources to the user (Grauer, n.d.; Simpson, 2008). This chapter discusses virtualization as a viable classroom methodology for providing students with course relevant hands-on experience (Simpson, 2008) while synchronizing course specific content in traditional on-ground and online courses (Pheils, 2010). More specifically, this chapter provides an overview of virtualization, detailing several open source tools, and offering possible applications for incorporation into other courses including free resources for sample content. Proof-of-concept is established through examples of successful usage at two colleges. The adoption of virtualization within course development may provide a solution that spans disciplines and offers students the ability to practice and further their studies beyond the classroom.

While the popular image of the Sherman Act is that of a “trust-busting” statute, conduct remedies have been more common than structural relief. This paper evaluates the effect on economic welfare of conduct remedies that have resulted from ten prominent Sherman Act monopolization cases. In general, we find that in some cases the behavioral relief has had no consequence other than the cost of litigation and cost of compliance; in other cases, the remedies probably reduced consumer welfare. Cases studied are United Shoe Machinery, AT&T, Std. Oil of California, IBM, United Fruit, Kodak, Safeway, GM, Jerrold, and Blue Chip Stamp.

Systemic industries comprise groups of firms making component products that are valued as complements by consumers (PC, automobiles, aircraft, networking). In this study, we investigate the distribution of research effort across the technological system by individual firms as a basis for building competitive advantage. Our empirical setting is a sample of component makers in the personal computer system. We show that even in a sample dominated by focused component manufacturers, diversified research effort in the broader technological system improves R&D productivity in the component technology. Broad scope R&D in the rest of the system also increases the marginal benefits of research efforts in the component technology, though at a diminishing rate. We explore the determinants of this complementarity between the scope of system level research and the focus on component level research, and derive implications for competitive advantage.

Purpose – This chapter argues that assistive technology itself, rather than a shared disabled identity, can be the basis for peer interaction and therefore serve as the basis for community. Specifically, prosthetic technology serves as a point of connection between amputees of different backgrounds.

Methodology – Data are from 20 in-depth qualitative interviews with a diverse group of men and women who lost legs or feet since 2002. The analysis of these interviews is enriched by ethnographic observation of support groups, mobility clinics, and visits to rehabilitation facilities.

Findings – Despite misgivings about support groups and socializing with others simply because of shared impairment, respondents reported connecting with peers through trading technical information and insights into prosthesis use. Thus, the notion of community may be most clearly understood in terms of interaction with shared objects and environments rather than shared identity.

Limitations – As with most qualitative studies, the findings here cannot be generalized to the greater amputee population in the United States.

Practical implications – The findings suggest that groups organized around activities that help people learn prosthetic legs can be the basis for community.

Social implications – This example suggests that communities of users can be a unique source of technical information about assistive technology that professionals cannot necessarily provide.

Value of paper – The analysis brings a unique perspective to the question of community and disability by drawing on sources from science and technology studies to theorize communities of users of assistive technology.
