Features of stratospheric aerosol lidar observations at Mauna Loa, 1974 - 1985

Lidar observations of the stratospheric aerosol over Mauna Loa were begun in the fall of 1974 and have continued to the present. An analysis of these observations has yielded interesting features of the stratospheric aerosol profile that change according to perturbed (from volcanic activity) and quiescent conditions. In the Mauna Loa lidar record there are two major perturbations that are contrasted, Fuego and El Chichon. The variations in relative aerosol cloud thickness, altitude of the maximum concentration and nonsymmetry are compared for the quiescent and perturbed time periods. Also, a climatology of annual average aerosol profiles is descrbied. A brief description will be given of procedures used to validate the lidar optical thickness information

Using Polya to Teach System Development Methodologies: Fostering a Role Perspective in IS Students

The role of IS is changing from a task perspective to a role perspective focused on aligning IS with business needs and goals. In this paper we present a problem solving perspective for teaching systems development methodologies as a means of fostering this shift in perspective in IS students. Polya\u27s formal problem solving process is synthesized with the traditional systems development life cycle. This synthesis makes explicit the tacit knowledge embedded in system development methodologies and enables the transfer of domain knowledge to the broader organizational context and the alignment of IS with business needs and goals
