    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    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

    Pioneering siRNA-Mediated Protection of Mammalian Cells against Zika Virus (MR-766) Infection

    Here, we present empirical data documenting the siRNA-mediated protection of cells after Zika virus (ZIKV) infection. siRNAs were designed to target well-conserved sequences across the ZIKV genome. Several delivery technologies were utilized. After the electroporation of 100 nM siRNA into human hepatocyte-derived carcinoma (Huh7) cells, the Feron Zv-2 sequence (specific to the ZIKV NS3 gene) yielded a cell viability of 150.3% ± 7.4% (SEM: n = 4) (p = 0.0004) relative to the cells treated only with the virus (33.9% ± 12%, SEM: n = 4). Furthermore, 100 nM siRNA Feron Zv-4 (specific to ZIKV 3’UTR) resulted in 119.1% ± 11.2% cell viability (SEM: n = 4) relative to the control cells treated with ZIKV (p = 0.0021). The cells were electroporated with siRNA prior to ZIKV infection and viability was monitored four days after this. Additionally, two novel siRNA delivery systems were tested. The first utilized recombinant Bacillus anthracis PA83 (octomer-forming mutants), co-incubated with the N-terminal 255 amino acids of B. anthracis lethal factor (LFn) fused in-frame with the RNA binding domain for human protein kinase R (LFn-PKR) at a concentration of 50 µg/mL (each). Here, baby hamster kidney (BHK) cells, treated with 100 nM siRNA Feron Zv-1, yielded 79.0% ± 4.0% viability relative to the control (50.2% ± 1.7%, SEM: n = 3) three days after exposure to ZIKV (p = 0.0096). Finally, HeLa exosomes loaded with siRNA Feron-Zv2 were incubated with Huh7 cells prior to ZIKV infection. For the siRNA-exosome treated cells, a viability of 123% ± 46% (SEM: n = 18), relative to 8% ± 16% (SEM: n = 18) for the same concentration of control HeLa exosomes, was recorded (p = 0.0416). In each instance, 0.3 moI was used and cell viability monitored using the PierceTM Firefly Luciferase Glow Assay Kit by Thermo ScientificTM. Here, we show for the first time that siRNA can significantly reduce ZIKV-induced cell killing. Future work will require quantitating ZIKV mRNA in relation to siRNA treatment, as well as testing the siRNAs and delivery systems within more complex models

    "Closing the R&D Gap, Evaluating the Sources of R&D Spending"

    No full text
    Both 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.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    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

    Letter from R. R. Zellick, Assistant Trust Officer at The Anglo California National Bank of San Francisco, to Joseph R. Goodman, regarding property owned by Dave Tatsuno. Zellick mentions a dispute between current tenants and Tatsuno, and that Tatsuno has asked Goodman to help locate trustworthy tenants.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    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
