The zirconocene-mediated synthesis of amines
No full textThe recent appearance of zirconium in organic synthesis is discussed. The formation and elaboration of Group (IV) metallacycles is reviewed, with emphasis on the formation of zirconocene η2-imine complexes. An introduction to the use of silicon as a removable molecular tether, and its oxidative removal to give a hydroxy group is given.The zirconocene(1-butene) cyclisation of 1, n-dienes and enynes is used to prepare a number of different zirconacycles which react with trimethylsilylcyanide to afford zirconocene iminoacyl complexes. A rearrangement to zirconocene η2-imine complexes occurs, and trapping with a range of unsaturated species gives functionalised cyclic amines on work up. The highly functionalised amines are produced in good overall yield from the starting materials in a one-pot transformation. Zirconaindanes were prepared from aryl zirconocenes via formation of zirconocene benzyne complexes through a C-H activation process and trapping with alkenes, and used in the trimethylsilylcyanide insertion reactions. Substituted alkynes insert regiospecifically into the zirconocene η2-imine complexes, giving allylic amines. Alkenes also insert, but show a lower reactivity. Isocyanates insert readily into zirconocene η2-imine complexes to give α-aminoamides on work up, and ketones insert to give 1,2-aminoalcohols.The insertions of isocyanates into zirconocene η2-imine complexes formed using a C-H activation route give a range of α-aminoamides.A range of 1, n-dienes and -enynes containing a silicon in the linking chain were prepared and successfully cyclised using zirconocene(1-butene). Intramolecular trapping os a zirconocene benzyne complex (generated by a C-H activation route) with a silicon tethered alkene was also achieved. Protic work up followed by oxidative cleavage of the silyl group using the Tamao oxidation gives hydroxyl containing products. Further elaboration of the intermediate zirconacycles before protonation/oxidation gave a range of highly functionalised cyclic and acyclic products in good overall yield. This is the first example of the use of a cleavable silicon tether in early transition metal-mediated cyclisations.</p
int_defects usage and validation examples
No full textThis dataset contains results of parametric finite element studies of structures containing crack-like flaws. All of the examples were created using the int_defects toolbox for MATLAB, which was designed for automating parametric finite element of this type. This toolbox and these associated examples are described in the following article: H. E. Coules & M. A. Probert, "Studying the interaction of crack-like flaws using the MATLAB toolbox int_defects", Engineering Fracture Mechanics
int_defects toolbox v1.2.0
No full textint_defects is a toolbox for MATLAB which automates parametric finite element studies of structures containing crack-like flaws. It is free and open-source software distributed under the terms of the MIT license (see included license file). int_defects is described in the paper: H. E. Coules & M. A. Probert, "Studying the interaction of crack-like flaws using the MATLAB toolbox int_defects", Engineering Fracture Mechanics. Further details of the scope and capabilities of the toolbox are given in the User Guide which is included with this distribution
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

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling 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
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
