The validation and verification of low-level code
No full textSoftware used in safety-critical applications must be correct; the consequences of an error may be too high even to contemplate. Therefore, until `real' compilers have been verified, no reliance should be placed on the correctness of the code which they produce. Also, real-time constraints sometimes make it necessary to develop software in a low-level language. Either way, low-level code must ultimately be verified. This dissertation describes SPADE-8080, a `safe subset' of the Intel 8080 assembly language supplemented with annotations (formal comments). As well as identifying the unverifiable aspects of assembly languages and eliminating them from the SPADE-8080 definition, the thesis explains how all legal SPADE-8080 programs can be translated into FDL, the modelling language of the Southampton Program Analysis and Development Environment (SPADE), for subsequent validation and formal verification with the SPADE flow and semantic analysis tools. The legality of a SPADE-8080 program is checked by the SPADE-8080 to FDL translator which will detect all deviations from the SPADE-8080 definition and, if no errors are found, will generate an FDL model of the program. This model includes previously `hidden' information such as status assignments, addressing modes and single-register/register-pair interactions. The model also contains check-statements from which shallow proofs can be constructed to demonstrate for instance the absence of overflow and correct indirection; they also allow the range analysis of array subscripts. Facilities for full program proof are provided in the form of SPADE-8080 proof annotations. Example flow analyses are discussed and the effectiveness of the flow analysis tools in detecting errors examined. The method used to construct a program's proof from its FDL model is also discussed and some examples given. Finally, future extensions and directions for the work are explored. (D71900/87)</p

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

No full textDispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

No full textAuthor, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
I consoli della nazione inglese a Livorno tra il 1665 e il 1673: Joseph Kent, Thomas Clutterbuck e Ephraim Skinner
No full text[The Consuls of the English Nation in Leghorn between 1665 and 1673: Joseph Kent, Thomas Clutterbuck and Ephraim Skinner]. Examining in detail the years 1665 to 1673 the article allows Villani to reconstruct the history of British consular presence in Livorno from the end of the 1500s. The author shows how the first two consuls – Raymond Dawkins and Thomas Hunt – were elected by Trinity House, a corporation of sea pilots, while only in 1621 the new consul, Richard Allen was elected by the Levant Company with the consent of the sovereign, James I. He has succeeded the Catholic Morgan Read, who had exercised the office from 1634 until his death in Livorno on May 29, 1665. After Read’s death Britain chose the enigmatic figure of Joseph Kent, which may have been the pseudonym of the Baronet John Abdy who adopted the name in order to mask his activities as a royalist spy during the Interregnum. Joseph Kent died in Rome on May 22, 1670 and was succeeded by Thomas Clutterbuck in 1669 and later Ephraim Skinner in 1671. These three consuls are interesting figures and their embassies were during a time when the litigious merchant community in Livorno experienced a marked increase in economic importance. The article also briefly outlines the work of other British consuls in the seventeenth century. The history of British consuls in the 1600s, along with their successors through to the eve of World War II, clearly shows Livorno’s important role in the political and diplomatic relations between Tuscany and England. In a important posthumous article on the English in Genoa between 1600s and 1700s published in Quaderni Storici Edoardo Grendi emphasized the importance consuls and envoys have for a nation “devoted to commerce.” He demonstrated how these “leading figures” not so much expressed relationships to the “community or national group of local settlement, but rather evolutions and dynamics of power associated with inter-state relations.” This essay is a detailed verification of this line of research
