Some Methodological Problems in Describing Old East Slavic Cyrillic Manuscripts and Printed Books
No full textRobert Mathiesen, Brown University, Providence, Rhode IslandThis paper was presented at the "International Data Bases for Medieval Manuscript Studies" conference at Katholieke Universiteit, Nijmegen, September 1987.Mathiesen emphasizes the importance of bibliographical description, particularly of Old Cyrillic manuscripts and printed books. He describes the "individual components of an ideal synchronic description of a codex-form book" into a "formal" part of the description and the "textual" part as a recommendation of the structure of manuscript and old printed book descriptions
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

An index of the South Slavic Manuscripts (33) and a list of the East Slavic Manuscripts (34) are provided. The bibliography falls on pages 35-48
"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.
Enterprise social technology in the context of business process improvement
No full textThis thesis is a qualitative study which identifies and conceptualises the affordances of enterprise social technology within the context of process improvement activities. Using a series of in-depth interviews, the research derived theoretical models that meticulously identifies and defines enterprise social technology affordances within process improvement contexts, showing their relationships to process improvement capabilities. A series of moderating variables effecting these relationships were also found. Based on the empirical evidence, the thesis proposes a series of normative guidelines to practice on how to best utilise enterprise social technologies for more effective and efficient process improvement efforts
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
Letter from R. R. Zellick, Assistant Trust Officer, Anglo California National Bank of San Francisco, to Joseph R. Goodman, October 2, 1942
No full textLetter 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 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

On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex
No full textComplex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. In mammals, about 50% of the mitochondrial DNA is encoding protein subunits of Complex I, and thus there is a strong correlation between defect Complex I and various degenerative diseases. Learning more about Complex I is thus important both for basic science and for medicine. Complex I contains three large membrane-spanning subunits, NuoL, NuoM and NuoN, that are homologous to one particular class of Na+/H+ antiporters and therefore are likely to harbor important components of the proton translocation machinery. MrpA and MrpD belong to this class of Na+/H+ antiporters and are found in a gene cluster containing seven genes, mrpA-G. In this work the transmembrane topology of the antiporter-like subunits was determined and their phylogenetic relationship investigated. In the analysis MrpA and MrpD formed distinct branches where NuoL grouped with MrpA and NuoM/N with MrpD. The result suggest that there are functional differences between the MrpA/NuoL and MrpD/NuoM proteins. The remaining proteins encoded by the mrp gene cluster were analyzed by PSI-BLAST, a bioinformatical search tool that more efficiently detect distant homologies. MrpC was found to be a NuoK homologue, and thus we conclude that NuoK, NuoL and NuoM where recruited together to Complex I, from the antiporter module MrpC, MrpA and MrpD. A functional difference between MrpA and MrpD was confirmed using Bacillus subtilis mrpA and mrpD deletion strains that were more salt and pH sensitive than wild type cells, but to a different extent. Recent work by Julia Steubers group at ETH Zürich showed that Complex I from Escherichia coli could translocate Na+, but this has hitherto not been regarded as a general property of proton pumping Complex I. By expressing the Complex I subunits NuoL and NuoM from the alpha-proteobacteria Rhodobacter capsulatus in the B. subtilis deletion strains we have demonstrated that these subunits are capable of Na+ translocation in vivo. Since R. capsulatus Complex I is more closely related to mitochondrial Complex I than to the E. coli enzyme, it is very likely that all Complex I enzymes have the ability to translocate Na+ as well as H+
