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
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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 use of the sterically demanding IPr∗ and related ligands in catalysis
The authors acknowledge the EC for funding through the seventh framework program SYNFLOW, the ERC (Advanced Investigator Award ‘FUNCAT’ to SPN) and the EPSRC. SPN is a Royal Society Wolfson Research Merit Award holder.This account highlights the synthesis and applications of one of the very bulky NHC ligands, IPr∗ (1,3-bis(2,6-bis(diphenylmethyl)-4-methylphenyl)imidazo-2-ylidene). This ligand and some of its derivatives have been found very effective in several catalytic applications and have enabled the isolation of highly reactive organometallic complexes. More specifically, applications of this ligand in Pd and Ni chemistry have permitted challenging transformations under mild reaction conditions and low catalyst loadings. We report the successes as well as the limitations encountered using transition-metal systems bearing this ligand-type. This report will hopefully serve as a guide to synthetic chemists, providing insights as to when the very sterically demanding IPr∗ ligand (and its congeners) and in a broader context, very bulky NHC ligands, should be used.Peer reviewe
Written Corrective Feedback: A Review of Studies since Truscott (1996)
Linguistic errors are pervasive in second language (L2) students’ writing. Depending on their gravity, the errors may cause a minor degree of irritation to the reader or even lead to total communication breakdown. As such, errors have always been a major concern to both students and teachers, and error correction has also assumed a central position in language teaching. Students generally expect that their errors will be pointed out and dealt with by their teachers. For L2 teachers, providing written corrective feedback (CF) on student writing has long been an essential practice. In fact, “grammar correction is something of an institution” (Truscott, 1996, p. 327) in L2 writing courses. Despite the fact that correcting students’ written errors is a time-consuming ordeal, and the endeavor is “fraught with uncertainty about its long-term effectiveness” (Ferris, 1999, p. 1), most L2 teachers have continued to slave over students’ errors in one form or another. As confirmed by a recent study on practitioners’ perspectives, the majority of teachers believe that students need CF and that written CF is overall an effective pedagogical practice (Evans et al., 2010)
