Key Issues

In electron energy loss spectroscopy (EELS), the near-edge region of a core-loss edge contains information on high-order atomic correlations. These correlations give details of the 3-D atomic structure which can be elucidated using multiple-scattering (MS) theory. MS calculations use real space clusters making them ideal for use in low-symmetry systems such as defects and interfaces. When coupled with the atomic spatial resolution capabilities of the scanning transmission electron microscope (STEM), there therefore exists the ability to obtain 3-D structural information from individual atomic scale structures. For ceramic materials where the structure-property relationships are dominated by defects and interfaces, this methodology can provide unique information on key issues such as like-ion repulsion and the presence of vacancies, impurities and structural distortion.An example of the use of MS-theory is shown in fig 1, where an experimental oxygen K-edge from SrTiO3 is compared to full MS-calculations for successive shells (a shell consists of neighboring atoms, so that 1 shell includes only nearest neighbors, 2 shells includes first and second-nearest neighbors, and so on).

Katherine Mansfield and Literary Influence seeks to understand influence, a powerful yet mysterious and undertheorised impetus for artistic production, by exploring Katherine Mansfield’s wide net of literary associations. Mansfield’s case proves that influence is careless of chronologies, spatial limits, artistic movements and cultural differences. Expanding upon theories of influence that focus on anxiety and coteries, this book demonstrates that it is as often unconscious as it is conscious, and can register as satire, yearning, copying, homage and resentment. This book maps the ecologies of Mansfield’s influences beyond her modernist and postcolonial contexts, observing that it roams wildly over six centuries, across three continents and beyond cultural and linguistic boundaries. Katherine Mansfield and Literary Influence identifies Mansfield’s involvement in six modes of literary influence - Ambivalence, Exchange, Identification, Imitation, Enchantment and Legacy. In so doing, it revisits key issues in Mansfield studies, including her relationships with Virginia Woolf, John Middleton Murry and S. S. Koteliansky, as well as the famous plagiarism case regarding Anton Chekhov. It also charts new territories for exploration, expanding the terrain of Mansfield's influence to include writers as diverse as Colette, Evelyn Waugh, Nettie Palmer, Eve Langley and Frank Sargeson.

The Relationship

The relationship between scripture and tradition has always been recognised as central to the controversy between More and Tyndale in the late 1520s and early 1530s. It was already one of the key issues in the English campaign against Luther instigated in 1521, and in the 1540s became one of the lynchpins of confessional identity both among Catholic theologians at Trent and in the English reformed articles of 1553. This is often seen as a doctrinal issue, but beneath the surface it can also be seen as part of a profound philosophical argument about the authority of oral and written evidence, an argument which goes back to the origins of Jewish and Christian religious practice and which continues to haunt the ecumenical concerns of today.
