could actually turn on personal stature and not necessarily social usefulness. Determinant #3 speaks to institutional requirements for each adaptation option and the decisionmaking frameworks with which they will be evaluated. Both need to be considered, and both can be evaluated independently

In this article, we examine, through the framework of the Technology Acceptance Model (TAM), some of the features that inform user acceptance of a digital library system implementation at agricultural universities in two developing countries: Kenya and Peru. This is a study not only examining

trust means in developing digital support services more generally, and how appreciating the fragility of trust can bring both risk and hope in uncertain and evolving worlds. DECONSTRUCTING TRUST Digital technology is ubiquitous. Daily rituals of the most mundane kind are enacted through smartphones

and communication technologies (ICT) toward the attainment of greater economic and social benefits and increased global competitiveness. Research has shown that the earlier focus on this phenomenon targeted physical access and diffusion of ICT as an indicator of digital readiness to reap ICT benefits. However

This thesis presents a new active mask (AM) framework and an algorithm for segmenta-tion of digital images, particularly those of punctate patterns from fluorescence microscopy. Fluorescence microscopy has greatly

We design and implement FD-Buffer, a buffer manager for database systems running on flash-based disks. Unlike magnetic disks, flash media has an inherent read-write asymmetry: writes involve expen-sive erase operations and as a result are usually much slower than reads. Therefore, we address this asymmetry in FD-Buffer. Specifically, we use the average I/O cost per page access as op-posed to the traditional miss rate as the performance metric for a buffer. We develop a new replacement policy in which we sepa-rate clean and dirty pages into two pools. The size ratio of the two pools is automatically adapted according to the read-write asymme-try and the runtime workload. We evaluate FD-Buffer with trace-driven simulations as well as experiments on real flash disks. Our evaluation results show that our algorithm achieves up to 40 % less I/O cost in simulation and up to 33 % improvement on the over-all performance on commodity flash disks, in comparison with the state-of-the-art flash-aware replacement policy. 1.

Digital signatures are an important primitive for building secure systems and are used in most real world security protocols. However, almost all popular signature schemes are either based on the factoring as-sumption (RSA) or the hardness of the discrete logarithm problem (DSA/ECDSA). In the case

for policy makers world-wide. Apart from the technical (e.g. security, network availability, speed) and regulatory (e.g. legal frameworks and standardization) challenges that need to be tackled there are a number of social concerns that require special concern. It is important for policy makers to see

As the integration of Internet-based social networking tools becomes increasingly popular in foreign language classrooms, the use of modern communication technologies is particularly critical in the context of less commonly taught languages (LCTLs), where student exposure to the target language
