Purpose The purpose of the study is to investigate the digital preservation practices in institutional repositories (IRs) in Africa. Design/methodology/approach Data were collected from the IRs developed in university libraries in Africa, and it was done in two phases. The phases are website investigation to identify the university libraries in Africa that have developed IR and online questionnaire. Findings Results from the study showed that the majority of IRs in Africa used DSpace software to manage their digital contents, and more than half of the IRs engage in information migration. The study also revealed that the majority of the responding institutions provide long-term digital preservation in their IR. Interestingly, the majority of the IRs has developed digital preservation policy to guide the implementation of digital preservation for IR contents. Finally, the majority of the respondents indicated that they do not have long-term funding and lack the necessary technical staff with required skills to handle and manage the IR. Research limitations/implications Because of language barriers, data were collected from only universities in English speaking countries in Africa. Practical implications The findings of this study will make librarians in universities in Africa and other developing countries understand the key issues relating to digital preservation and longevity. Originality/value The findings of this study will inform information professionals, librarians in developing countries that are planning to create IRs and provide long-term digital preservation of electronic resources in their institution.

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.
