Total systems intervention and human inquiry: The search for a common ground

Total Systems Intervention (TSI) is an approach to intervening in problem situations which has much to offer where complex interacting issues need to be addressed by the complementary use of intervention methodologies. That such an approach has much in common with Action Research (AR) has been recognized, with much recent effort being devoted to the relationship between AR and Critical Systems Thinking (CST), the theoretical endeavor underpinning TSI. This paper further develops this line of debate and relates AR or Human Inquiry (HI) more directly to TSI, using an information systems intervention to enhance the study. The outcome is a demonstration of how TSI implicitly uses techniques informed from the field of Action Research, and how a more thorough synthesis of HI with TSI might serve to improve the overall intervention process.

GIANT MAGNETORESISTANCE EFFECTS IN Co／Cu （111） SUPERLATTICE

We present a spin-dependent scattering theory to explain the new type of magnetoresistance effect and magnetization in Co/Cu(111) su-perlattice with atomically smooth interfaces. Our model is simple, but the calculated results are consistent with the experimental ones.
