Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Power Aware Network Swapping for Wireless Palmtop PCs
No full textVirtual memory is considered to be an unlimited resource in desktop or notebook computers with high storage capabilities. However, in wireless mobile devices, like palmtops and personal digital assistants (PDAs), storage memory is limited or absent due to weight, size, and power constraints, so that swapping over remote memory devices can be considered as a viable alternative. However, power-hungry wireless network interface cards (WNICs) may limit the battery lifetime and application performance if not efficiently exploited. In this paper, we study performance and energy of network swapping in comparison with swapping on local microdrives and flash memories. We report the results of extensive experiments conducted on different WNICs and local swapping devices, using both synthetic and natural benchmarks. Our study points out that remote swapping over power-manageable WNICs can be more efficient than local swapping, especially in bursty workload conditions. Such conditions can be forced where possible by reshaping swapping requests to increase energy efficiency and performanc
Il software open-source nel sistema universitario italiano
No full textIl software open source ha sempre trovato una forte spinta propulsiva nell’ambiente accademico, che ha contribuito in maniera decisiva al suo sviluppo. Pur tenendo presente che prodotti open source sono ormai largamente diffusi nel mondo del software industriale, può essere interessante cercare di capire quanto nell’ambiente universitario è poi concretamente anche adottato per le infrastrutture e i servizi. Il censimento del software open source vuole proprio rispondere a questa domanda per offrire una base di partenza da utilizzare per monitorare in futuro l’evoluzione di queste tecnologie. La conoscenza della diffusione dei software open source all’interno del sistema universitario italiano può essere di interesse non solo per il sistema stesso, ma anche per la definizione di politiche strategiche per la pubblica amministrazione in senso più generale
