A denomination’s dealings with difference : considering recategorization and mutual intergroup differentiation in the context of The United Church of Canada

104 leaves : ill. ; 29 cm.Includes abstract and appendix.Includes bibliographical references (leaves 91-104).This thesis, in a novel interdisciplinary fashion, examines The United Church of Canada (UCC) from a social-psychological framework of Social Identity Theory and Categorization. Focusing on four broad ingroup-outgroup case studies—ecumenical, interfaith, overseas mission and First Nations-UCC relations—this study surveys and subsequently analyzes the UCC’s national discourse and initiatives with respect to two specific, well-supported strategies for reducing intergroup conflict: Recategorization and Mutual Intergroup Differentiation. Looking at the denomination’s historical development through the lens of these social-psychological models not only highlights a normative pattern of moving from initial positions of ingroup bias to recategorized and mutually differentiated partnerships, but also proposes new understandings of past, present, and possible future issues relevant to the UCC

Application of the finite-temperature Lanczos method for the evaluation of magnetocaloric properties of large magnetic molecules

We discuss the magnetocaloric properties of gadolinium containing magnetic molecules which potentially could be used for sub-Kelvin cooling. We show that a degeneracy of a singlet ground state could be advantageous in order to support adiabatic processes to low temperatures and simultaneously minimize disturbing dipolar interactions. Since the Hilbert spaces of such spin systems assume very large dimensions we evaluate the necessary thermodynamic observables by means of the Finite-Temperature Lanczos Method.Comment: 7 pages, 10 figures, invited for the special issue of EPJB on "New trends in magnetism and magnetic materials
