Polarized Emission of Molecular Film With Lanthanide (Ⅲ) Complex

1 Results In the coordination system by using complexation with organic ligand, the ff emission of lanthanide(Ⅲ) (Ln(Ⅲ)) is induced the excitation energy transfer form the organic chromophore under the light-irradiation. However, there are not so much number of reports to discuss the energy relaxation mechanism in such complexes with Ln(Ⅲ). Recently, we succeeded firstly to estimate the rate constant of the energy transfer between the ligand and Ln(Ⅲ) in Pr(Ⅲ)-phenanthroline analogs[1]. Here, we will di...

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.
