    Appropriate Similarity Measures for Author Cocitation Analysis

    Get PDF
    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

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

    Get PDF
    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

    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

The record of Ectobia albicincta from Eleni peak, Rila Mts., 2000 m (Frey-Gessner 1893), also mentioned in the publication of Nedelkov (1908), later determined as Ectobius lapponicus morpha erythronota by Buresch & Peschev (1957), probably refers to Ectobius balcani considering the distribution and biology of these species. Ramme (1923) synonymised Ectobia lapponica subsp. nigra (Vitosha Mt.), with Ectobius lapponicus balcani, which was later considered a valid species by Ramme (1951). The material from Aliboutoush Mt. reported by Drenowski (1936) as E. lapponica and part of the material from Kresna gorge reported by Drenski (1939) as E. laponica refers to Ectobius balcani considering the distribution and biology of these species. Distribution in Bulgaria (Fig. 72). The species inhabits varied semi-dry to humid habitats from the lowlands to 2300 m alt. but is mainly found in the subalpine and alpine belts. It does not seem to occur to the north of the Stara Planina Mountains. Around the lower limit of distribution it keeps on diverse vegetation (grass-shrub, low vegetation and leaf litter). Studied material. 1215 specimens (909 adults, 306 nymphs) and 10 oothecae. General distribution. The distribution range of E. balcani covers the Balkan Peninsula (Croatia, Bosnia & Herzegovina, Albania, R Macedonia, Greece), northwards reaching Austria and Hungary, and in the east extending up to the Fore-Caucasus.Published as part of Hristov, Georgi H. & Chobanov, Dragan P., 2016, An annotated checklist and key to the Bulgarian cockroaches (Dictyoptera: Blattodea), pp. 351-388 in Zootaxa 4154 (4) on pages 353-354, DOI: 10.11646/zootaxa.4154.4.1, http://zenodo.org/record/26482

    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

    Get PDF
    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

    Phyllodromica pallida Brunner von Wattenwyl 1882

    Phyllodromica pallida (Brunner von Wattenwyl, 1882) Figures 12, 26 49, 63, 69, 71 The records for Phyllodromica pallida from Bulgaria (Harz 1984) were based on material collected from Pirin Mts. and identified by Chládek. After photographic observation of the materials in the Chládek’s collection the specimens were referred to Phyllodromica carniolica (compare the data for the latter species). This species is widespread on the Balkan Peninsula and is recorded for Croatia, Bosnia and Herzegovina, and Greece. According to own unpublished data (G. Hristov, unp.) the species occurs also in Albania and R Macedonia. Even though Ph. pallida has not yet been recorded, on the territory of Bulgaria, its occurrence in this country is very probable, based on the wide distribution of this species in the adjacent territories. The species usually inhabits meso- and xerothermic Oak and Hornbeam forests and meadows, dwelling within leaf litter, in low grass and shrubs.Published as part of Hristov, Georgi H. & Chobanov, Dragan P., 2016, An annotated checklist and key to the Bulgarian cockroaches (Dictyoptera: Blattodea), pp. 351-388 in Zootaxa 4154 (4) on page 360, DOI: 10.11646/zootaxa.4154.4.1, http://zenodo.org/record/26482
