This study explored the publication pattern of Canadian computer scientists and compared the impact of conference papers and journal articles published by these researchers. It was found that conference proceedings are the preferred venue for scholarly communication, but the impact of conference papers is not comparable to that of journal articles. The potential reasons for the lower impact of conference papers are discussed, and possible approaches to improve the current scholarly communication system in computer science are proposed.

Studies of clinical populations that combine MRI data generated at multiple sites are increasingly common. The Canadian Biomarker Integration Network in Depression (CAN-BIND; www.canbind.ca) is a national depression research program that includes multimodal neuroimaging collected at several sites across Canada. The purpose of the current paper is to provide detailed information on the imaging protocols used in a number of CAN-BIND studies. The CAN-BIND program implemented a series of platform-specific MRI protocols, including a suite of prescribed structural and functional MRI sequences supported by real-time monitoring for adherence and quality control. The imaging data are retained in an established informatics and databasing platform. Approximately 1300 participants are being recruited, including almost 1000 with depression. These include participants treated with antidepressant medications, transcranial magnetic stimulation, cognitive behavioural therapy and cognitive remediation therapy. Our ability to analyze the large number of imaging variables available may be limited by the sample size of the substudies. The CAN-BIND program includes a multimodal imaging database supported by extensive clinical, demographic, neuropsychological and biological data from people with major depression. It is a resource for Canadian investigators who are interested in understanding whether aspects of neuroimaging — alone or in combination with other variables — can predict the outcomes of various treatment modalities.

Individuals with different backgrounds such as engineering, medicine, industrial design, business, healthcare management and computer science often contribute to the design of a medical innovation. But how do such heterogeneous design participants actually combine their expertise to develop a medical device? Adapting Bucciarelli’s concept of “object worlds”, which recognises that those who contribute to a design process inhabit different worlds and see the object of design differently, this paper examines the perspectives of 8 design participants who contributed to the design process of three Canadian medical devices. In-depth analyses of semi-structured interviews clarified what design participants saw through their particular “lens”, how their responsibilities, knowledge and motivations combined and how they engaged into the design process.
