Food Bloggers and Their Perceptions of Digital Preservation

This study explored the perceptions of food bloggers on digital preservation of their blogs through an anonymous, web-based survey. It also examined if the blog format changes authenticity. Survey questions asked for data on blogging behavior, technology and preservation and deletion, editing and loss. The survey was shared through Facebook pages and groups, discussion boards and forums, Twitter and Tumblr. This study looked at how bloggers view their blogs long-term. The study assessed if bloggers view their content as possessing enduring value. Furthermore, it ascertained if the participants have taken steps to preserve their blogs. The majority of the respondents were reasonably confident in their technical skills for blog maintenance. Despite this, half were not using any strategy to save their blog. Respondents questioned the enduring value of their blogs. Some sub-group differences found between hobby bloggers and for profit bloggers. In addition, issues of authenticity were not conclusively determined.Master of Science in Library Scienc

ZnO and MgZnO Nanocrystalline Flexible Films: Optical and Material Properties

An emerging material for flexible UV applications is MgxZn1−xO which is capable of tunable bandgap and luminescence in the UV range of ~3.4 eV–7.4 eV depending on the composition x. Studies on the optical and material characteristics of ZnO and Mg0.3Zn0.7O nanocrystalline flexible films are presented. The analysis indicates that the ZnO and Mg0.3Zn0.7O have bandgaps of 3.34 eV and 4.02 eV, respectively. The photoluminescence (PL) of the ZnO film was found to exhibit a structural defect-related emission at ~3.316 eV inherent to the nanocrystalline morphology. The PL of the Mg0.3Zn0.7O film exhibits two broad peaks at 3.38 eV and at 3.95 eV that are discussed in terms of the solubility limit of the ZnO-MgO alloy system. Additionally, external deformation of the film did not have a significant impact on its properties as indicated by the Raman LO-mode behavior, making these films attractive for UV flexible applications
