Dialogic Ethics: Leadership And The Face Of The Other, Karen Lollar

Journal of the Association for Communication Administration

Foundational to a relational ethic is the belief that healthy human existence requires respect for others, respect that does not work to reduce their otherness to the sameness that is familiar. It is not enough that the face of another person arouses awareness. What pragmatic action does it require? This article explores the application of a Levinasian ethic on day-to-day practice in the academy. Weaving together short vignettes from daily work practice with principles of ethics from Emmanuel Levinas (1969, 1997), the author concludes with a vision of the possibility of creating a dwelling place based on dialogic ethics as …

Liquid Sorption Properties And Structural Changes Of Metal-Organic Frameworks Of Cobalt Nitrate And 4,4'-Bipyridine, Kathryn Mauger-Sonnek

Dissertations and Theses @ UNI

Metal-organic frameworks consist of metal ions connected by organic ligands. When the metal ions and organic ligands link together in the right geometry, polymeric and infinite 1D chains or 2D and 3D networks are formed. Porous metal-organic frameworks were synthesized from the organic ligand 4,4′-bipyridine (bpy) and cobalt(II) nitrate. The metal-organic frameworks synthesized in this study grew into both a previously known 2D bilayer structure, [Co2(bpy)3(NO3)4]n, and a new, orange 1D chain structure, [Co(bpy)NO3)2(H2O)2]n, within ethanol. It was found that the presence of water was the main factor of causing formation of the orange 1D chain crystals. Drying the orange …
