This paper studies a model of interpersonal bundling, in which a monopolist offers a good for sale under a regular price and a group purchase discount if the number of consumers in a group– the bundle size– belongs to some menu of intervals. We find that this is often a profitable selling strategy in response to demand uncertainty, and it can achieve the highest profit among all possible sellin...

In this paper, the author proposes that the longterm health of engineering education in Canada would be served well by separating applied science and engineering. The rationale for such a separation is presented, along with some suggestions for how the two streams, each leading to a doctorate, could be implemented.

Action research and design research are two prominent research approaches in information systems. These two research approach have been claimed to be similar according to several conducted comparisons. There are, however, other claims that they are decisively dissimilar. Some scholars have proposed integrations of these two research approaches, which however show great diversity. These diversit...

The Population Studies Research Network of Cancer Care Ontario hosted a strategic planning workshop to establish an agenda for a prevention intervention research program in Ontario, including priority topics for investigation and design considerations. The two-day workshop included: presentations on background papers developed to facilitate participants' preparation for and discussions in the w...

Device evaluation, which is an essential skill set for the respiratory therapist, ranges from comparing manufacturer's specifications to comprehensive device testing, either with patients or on the bench. Good device evaluations help guide decisions about device selection, procedure development, and risk and failure analysis. Poor evaluations cost time and money and fail to return value. Manufa...

Problem-finding is a complex part of the innovation process. The growth path from motivation to an idea and finally to an innovation requires communication of different viewpoints. This research aims to answer how mobile learning tools could facilitate creativity by supporting both individual reflection and collaboration around ideas. The use of portfolios and web logs in this context is discus...

Risk perceptions are important in HIV research and interventions; mixed results were found between HIV-related perceptions and behaviors. We interviewed 377 sexually active injecting drug users in China, finding mixed associations between HIV-related risk perception assessed by two general measures and two previous risk behaviors (syringe sharing: p<.05; unprotected sex: p>.05) - partially supp...

The results of this field study are generally consistent with those from a previous laboratory experiment which showed that the relationship between budgetary participation and performance is moderated by the personality variable internal-external locus of control . Internals (individuals who feel that they are in control of their own destinies) appear more job satisfied and perform better unde...

This paper challenges the argument that data protection legislation may harm research by unduly restricting the flow of personal health information. I unpack the assumption that privacy is an individual right that must give way to research as a social good, and explore how data protection laws facilitate the flow of information for research purposes. I conclude that researchers should embrace d...

Another issue that trouble the novice is how much statistical knowledge one needs to have. There is no straight answer to this question; we feel that the information provided in this article is probably the bare minimum needed by most, if not all, researchers embarking on a research project. What about performing your own statistical analysis using statistical software? Although ability to hand...
