Multilevel Research in Information Systems: Concepts, Strategies, Problems, and Pitfalls
Information systems (IS) researchers often explore complex phenomena that result from the interplay between technologies and human actors; as such, IS research frequently involves constructs found at multiple levels of analysis, although rarely recognized as such. In fact, our targeted review of the IS literature found minimal explicit consideration of the issues posed by multilevel research al...
متن کاملMicro-Catchment Rain Water Harvesting Systems and fruit seedlings: Strategies and Research challenges
The use of Rain-Water Harvesting (RWH) systems for fruit seedling planting in addition to helping to make optimal use of runoff and soil and water conservation, will also help the production of agricultural and horticultural products. Accordingly, this study has focused on the investigation of the effects of RWH systems on the growth of fruit seedlings and their establishment, especially i...
متن کاملMultilevel Passenger Screening Strategies for Aviation Security Systems
Passenger prescreening is a critical component of aviation security. This paper introduces the Multilevel Allocation Problem (MAP), which models the screening of passengers and baggage in a multilevel aviation security system. A passenger is screened by one of several classes, each of which corresponds to a set of procedures using security screening devices, where passengers are differentiated ...
متن کاملCooperativity in biological systems
Living organisms can sense and respond to external and internal stimuli. Response isdemonstrated in many forms including modulation of gene expression profiles, motility,secretion, cell death, etc. Nevertheless, all forms share a basic property: they depend on sensingsmall changes in the concentration of an effector molecule or subtle conformational changes ina protein and invoking the appropri...
متن کاملMultilevel Systems and Policy Multilevel Systems and Policy
A formal theory of multilevel systems is needed for modelling the outcomes of policy. The dynamics of social systems are coupled between levels and models that do not reflect this are incomplete and a poor basis for policymaking. The structures developed here are necessary for the new kinds of models and computer simulations needed to support policy makers as they tackle the problems of an incr...
