    Notes: This paper describes an imaging system that was developed to aid industrial bin picking tasks. The purpose of this system was to provide accurate 3D models of parts and objects in the bin, so that precise grasping operations could be performed. The technology described here is based on two types of sensors: range mapping scanners and video cameras. The geometry of bin contents was reconstructed from range maps and modeled using superquadric representations, providing location and parts surface information that can be employed to guide the robotic arm. Texture was also provided by the video streams and applied to the recovered models. The system is expected to improve the accuracy and efficiency of bin sorting and represents a step toward full automation.

    Notes: Recent projections by social scientists indicate that by the year 2000 almost half the work force will be comprised of women. Information systems (IS) literature reports that women are underrepresented: only about one-third of IS employees are female. This may suggest that IS women professionals may be engaging in practices that restrict their entry, promotion and retention. Attempts to examine the career success outcomes of men and women in IS using the human-capital paradigm. Presents results, based on the survey responses of about 348 employees in the IS field, which suggest that significant gender differences exist. For instance, women were found, on average, to be somewhat younger and less experienced then were men in lower-level positions and to receive lower salaries than do men even when age, work experience and job level were controlled. Moreover, women have fewer opportunities to interact with people outside their departmental boundaries. Discusses the relevance of these results and presents viable options for fostering the careers and improving the retention of women in the IS field.

    Notes: Media richness theory argues that different media are more or less appropriate for different tasks. Social information processing theory (SIP) explains a motivation and method guiding such technology adoption. In light of these theories, and the field's lack of understanding of media effects on group development, this article investigates the development of two important group process factors - cohesion development and process satisfaction - in two different studies of groups supported by electronic meeting systems. Results indicate that initial levels of cohesion and process satisfaction differ depending on the medium (and its inherent richness) and, consistent with SIP, cohesion and process satisfaction increase over time in all types of electronic support, despite relative differences in media richness.

    Notes: Group members' attitudes toward social processes and media properties are likely to change as members interact and gain experience with each other and technology in computer-supported environments. Moreover, these attitudes are likely to evolve differently. This study examines computer-supported groups of four over a series of four sessions working on a collaborative writing task. Results from this study indicate that group-related attitudes, i.e. social perceptions, tend to change sooner, and to a greater extent, than media-related ones. A possible explanation for these differences is that computer media have certain physical properties that cannot be easily altered by users. In contrast, group-related structures appear to be much more malleable. These results imply that, for example, groups can, with the right assistance, develop positive group attitudes rather quickly which tend to last over time. In contrast, attitudes towards technical systems tend to evolve more slowly and, when system designs are flawed or users are not well trained on system features, managers may be faced with persistent negative user attitudes. Thus, understanding how social and technical attitudes evolve is critical for managers who want to improve group processes.
