Notes. Trocnadella was originally described based on females of two species from India. Viraktamath (1979) redescribed the genus and included T. arisana (Matsumura), illustrating the male genitalia for the first time. Anufriev (1987) treated Straganiassus Anufriev and Anufrieviella Nast as junior synonyms of Trocnadella. Species of the genus closely resemble Trocniassus gen. nov. (described below) but differ in lacking a row of cucullate setae on the first hind tarsomere and in having the aedeagus fused to the connective. The genus presently comprises ten species (see Checklist). A key to species cannot be provided at present because the genus is in need of comprehensive revision. The identities of some species described from China are uncertain because the original descriptions and illustrations (e.g., Li 1995) are difficult to interpret and specimens were not available for study. Also, the two species originally included in the genus (Pruthi 1930) were described based on females and males are needed for positive identification.Published as part of Dai, Wu, Dietrich, Christopher H. & Zhang, Yalin, 2015, A review of the leafhopper tribe Hyalojassini (Hemiptera: Cicadellidae: Iassinae) with description of new taxa, pp. 1-142 in Zootaxa 3911 (1) on pages 34-35, DOI: 10.11646/zootaxa.3911.1.1, http://zenodo.org/record/25371
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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
UK Renal Registry 16th annual report: chapter 4 demography of patients waitlisted for renal transplantation in the UK: national and centre-specific analyses
No full textIntroduction: for suitable patients, renal transplantation is considered the optimal modality of renal replacement therapy, with availability of donor organs limiting the number of transplants undertaken. The 2006 kidney allocation policy was developed to ensure equity of allocation to patients on the transplant waiting list, whilst still achieving a good donor/recipient match. This study aims to describe the characteristics of the kidney transplant waiting list and variations in median waiting times. Methods: demographics and clinical characteristics of all patients listed for a kidney only transplant in the UK on 1st January 2011 were examined. Renal unit variations were explored. Patients listed between January 2006 and December 2009 were included in analysis of waiting times to transplant. Results: at the beginning of 2011, there were 6,699 patients registered active for kidney only transplant in UK; a prevalence rate of 107 pmp. The median age of prevalent listed patients was 53 years, with 8% aged 70 or above. Of the patients listed, 84% had started renal replacement therapy (RRT), 59% were male, 28% were from ethnic minorities, 50% had blood group type O, 28% were defined as difficult to HLA match and 23% were highly sensitised (calculated HLA antibody reaction frequency 85%). Median waiting time to transplant was 38 months. Waiting time was shorter for White patients (36 months) compared to Asian or Black patients (46 months), and was doubled in highly sensitised compared to un-sensitised patients. Conclusions: intercentre variation was observed in the rate of wait-listing and in the proportion of listed patients across different ethnic groups, age, blood groups and level of sensitisation. This may reflect differences in baseline population characteristics as well as individual centre practice patterns. Median waiting times differ significantly across blood groups, degree of sensitisation and ethnic grou

No full textGoing 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

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
