    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Enhancing Eucalyptus Community Cloud

    In the last few years, the cloud computing model has moved from hype to reality, as witnessed by the increasing number of commercial providers offering their cloud computing solutions. At the same time, various open-source projects are developing cloud computing frameworks open to experimental instrumentation and study. In this work we analyze Eucalyptus Community Cloud, an open-source cloud-computing framework delivering the IaaS model and running under the Linux operating system. Our aim is to present some of the results of our analysis and to propose some enhancements that can make Eucalyptus Community Cloud even more attractive for building both private and community cloud infrastructures, but also with an eye toward public clouds. In addition, we present a to-do list that may hopefully help users in the task of configuring and running their own Linux (and Windows) guests with Eucalyptus
