Technical alignment

This essay discusses the importance of the areas of infrastructure and testing to help digital preservation services demonstrate reliability, transparency, and accountability. It encourages practitioners to build a strong culture in which transparency and collaborations between technical frameworks are valued highly. It also argues for devising and applying agreed-upon metrics that will enable the systematic analysis of preservation infrastructure. The essay begins by defining technical infrastructure and testing in the digital preservation context, provides case studies that exemplify both progress and challenges for technical alignment in both areas, and concludes with suggestions for achieving greater degrees of technical alignment going forward

Ethnographic methods in academic libraries: A review

Research in academic libraries has recently seen an increase in the use of ethnographic-based methods to collect data. Primarily used to learn about library users and their interaction with spaces and resources, the methods are proving particularly useful to academic libraries. The data ethnographic methods retrieve is rich, context specific, and often difficult to collect via other methods. This review provides an overview of research demonstrating how ethnography can be applied to learn about a variety of issues in academic libraries, ranging from space use to a way of teaching new students about library resources and facilities

Speech Watermarking through Parametric Modeling

A general formulation for speech watermarking through parametric modeling is suggested, then the paper focuses on a watermarking technique based on linear-predictive (LP) modeling of speech. In the particular strategy employed here, information is embedded by modifying the autocorrelation values of the original speech. The amount of information that can be embedded is subject to fidelity constraints. The modified LP coe#cients derived from the new set of autocorrelation values are used for reconstructing the watermarked speech. The perceptual quality of the watermarked speech depends on the relative energy of the embedded watermark, the watermark sequence used, and the LP model order. Robustness of the technique to various signal processing operations and attacks like compression, cropping, and additive noise are studied via experiments on a small speech application. Factors a#ecting watermark robustness and related security issues are also discussed

Assessing awareness of library services:an ethnographic examination of bachelor students at two Czech technology universities

In this paper, the authors present interim research results from an ongoing ethnographic examination of eight engineering undergraduate students from two technology universities in Prague, Czech Republic. A multi-layered data gathering strategy was employed, including semi-structured in-person interviews as well as in situ and virtual observations of participants interacting with learning environments. This data enabled the authors to examine whether or not students are aware of library services. “Library services” are here broadly defined to include not only traditional support services but also new, emerging areas of activity which can be categorized under the broader concept of undergraduate student support. Findings indicate very poor awareness of library offerings although participants were aware of the library as a study space. The authors additionally touch briefly upon the concept of “backward design” for service development, in which research data is gathered and considered prior to service design and launch
