Abstract

Increasing globalization has created tremendous opportunities and challenges for organizations and societies. Consequently, a broad range of information technologies to better support the collaboration of diverse, and increasingly distributed, sets of participants is ever more utilized. Arguably, the success of such technology-mediated collaboration is dependent upon the quality of each individual's contributions; however, although individuals' motivations to do their best could be significantly influenced by the design of a system's human-computer interface, this area has received little attention within the context of group collaboration environments. We fill this gap by integrating research from human-computer interaction, motivation, and technology-supported group work to theoretically derive mechanisms for increasing each individual's motivation within a collective setting. Specifically, we manipulate the interface of a computer-mediated idea generation system (a widely used collaboration tool) to enhance the system's motivational affordance, i.e., the system's properties that fulfill users' motivational needs. Results from two studies demonstrate that by embedding the theoretically derived mechanisms 'providing feedback' and 'designing for optimal challenge' into the collaboration environment, significant performance gains were realized. The results suggest that even slight manipulations of the human-computer interface can contribute significantly to the successful design of a wide variety of group collaboration environments. Key words: human-computer interaction; motivational affordance; collaboration; computer-mediated idea generation; goal setting; performance feedback History: Received January 12, 2008; accepted September 26, 2009, by Sandra A.

Abstract

This paper describes the LSO/LuYAP phoswich detector head developed for the ClearPET small animal PET scanner demonstrator that is under construction in Lausanne within the Crystal Clear Collaboration. The detector head consists of a dual layer of 8 x 8 LSO and LuYAP crystal arrays coupled to a multi-anode photomultiplier tube (Hamamatsu R7600-M64). Equalisation of the LSO/LuYAP light collection is obtained through partial attenuation of the LSO scintillation light using a thin aluminum deposit of 20-35 nm on LSO and appropriate temperature regulation of the phoswich head between 30 [degrees]C to 60 [degrees]C. At 511 keV, typical FWHM energy resolutions of the pixels of a phoswich head amounts to (28[+ or -]2)% for LSO and (25[+ or -]2)% for LuYAP. The LSO versus LuYAP crystal identification efficiency is better than 98%. Six detector modules have been mounted on a rotating gantry. Axial and tangential spatial resolutions were measured up to 4 cm from the scanner axis and compared to Monte Carlo simulations using GATE. FWHM spatial resolution ranges from 1.3 mm on axis to 2.6 mm at 4 cm from the axis. Index Terms--Positron emission tomography, phoswich detector, depth-of-interaction, small animal PET scanner.
