Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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 PDFBoth 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.

Montane Atlantic Forest Rat Delomys altimontanus French: Délomys montagnard / German: Atlantische Bergwaldratte / Spanish: Rata de bosque atlantico de montana Other common names: Montane Delomys Taxonomy. Delomys altimontanus P. R. Goncalves & J. A. Oliveira, 2014, Campos do [tatiaia, 2450 m, Itatiaia National Park, Rio de Janeiro, Brazil. This species is monotypic. Distribution. Restricted to Mantiqueira Mts (Caparao and Itatiaia Mts) in SE Brazil. Descriptive notes. Head-body 130-134 mm, tail 123-126 mm, ear 20-22 mm, hindfoot 31-32 mm; weight 25-72 g (mean 45 g). The Montane Atlantic Forest Rat is a medium-sized species of Delomys, with soft and long dorsal pelage, predominantly cinnamon-brown grizzled with yellow but becoming brighter orange along flanks. Tail is as long as head-body length and strongly bicolored throughout most ofits length. Six mammae are present. Chromosomal complement is 2n = 82 and FN = 86. Habitat. Humid montane forests and shrublands in the Caparaé mountain range at elevations above 1800 m and forested habitats near streams and never on open mesas in the Itatiaia mountain range above 2100 m. Food and Feeding. No information. Breeding. No information. Activity patterns. The Montane Atlantic Forest Rat is probably nocturnal. Movements, Home range and Social organization. No information. Status and Conservation. Not assessed on The [UCN Red 1st. Bibliography. Bonvicino et al. (1997), Gongalves & Oliveira (2014).Published as part of Don E. Wilson, Russell A. Mittermeier & Thomas E.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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 Road for SEEM: a reference framework
No full textThe Single European Electronic Market (SEEM) concept was first introduced by a workshop organised in October 2002 by Unit F4 (New Working Environments) of the European Commission DG Information Society. The SEEM vision is towards an Internet-based structured market where companies can collaborate without geographical and technological restraints, thus overcoming the limits of the hundreds of business services, vertical portals and private solutions each adopting its own specific model
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
Get PDFWe 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
