Sant'Andrea della Valle, Cenotaphs of Popes Pius II and Pius III
No full textThe tomb of Pius II, showing relief; In the first two bays of the nave are the Renaissance cenotaphs of Popes Pius II (died 1464) and Pius III (died 1503), both of the Piccolomini family. Both were originally interred in Old St Peter's, and brought to Sant'Andrea della Valle (the church having been built by a Piccolomini patron) in 1614. Paolo Romano (formerly known as Paolo Taccone) had been the favorite sculptor of Pius II and created his funerary chapel (ca. 1470; destroyed) in St. Peter's. The iconography of the cenotaph may follow that work. The later cenotaph of Pius III was modeled on that of Pius II
Providing e-Transaction Guarantees in Asynchronous Systems with No Assumptions on the Accuracy of Failure Detection
No full textIn this paper, we address reliability issues in three-tier systems with stateless application servers. For these systems, a framework called e-Transaction has been recently proposed, which specifies a set of desirable end-to-end reliability guarantees. In this article, we propose an innovative distributed protocol providing e-Transaction guarantees in the general case of multiple, autonomous back-end databases (typical of scenarios with multiple parties involved within a same business process). Differently from existing proposals coping with the e-Transaction framework, our protocol does not rely on any assumption on the accuracy of failure detection. Hence, it reveals suited for a wider class of distributed systems. To achieve such a target, our protocol exploits an innovative scheme for distributed transaction management (based on ad hoc demarcation and concurrency control mechanisms), which we introduce in this paper. Beyond providing the proof of protocol correctness, we also discuss hints on the protocol integration with conventional systems (e.g., database systems) and show the minimal overhead imposed by the protocol

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
