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.
Prospective registry of symptomatic severe aortic stenosis in octogenarians: a need for intervention
No full textThis work was supported as a subproject (09-2007) by the Spanish National Centre for Cardiovascular Research (CNIC)–Scholarship for translational research and as a research project from the Catedra Asisa-Universidad Europea de Madrid (UEM) (CAT001206C).Martínez-Sellés, M., Gómez Doblas, J.J., Carro Hevia, A., García de la Villa, B., Ferreira-González, I., Alonso Tello, A., Andión Ogando, R., Ripoll Vera, T., Arribas Jiménez, A., Carrillo, P., Rodríguez Pascual, C., Casares i Romeva, M., Borras, X., Cornide, L., López-Palop, R
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
The Spanish Regional Policy: an assessment of economic incentives during the period 1988-2003
No full textTwo main challenges influence the design of regional policies carried out by European, National and Regional policy makers. The first is the shift towards a knowledge-based economy, where enterprise competitiveness is increasingly linked to intangible assets. The second is the enlargement of the European Union that means important changes in the European Union marketplace and the possibilities of intervention in some less favoured regions. Until today, Regional Policy in many European Union countries has principally been founded on incentives for the creation of employment and investment in tangible assets. In this context, Spanish Regional Policy has been formulated, on the one hand, to achieve decentralisation of the entities responsible for its promotion and, on the other, to foster co-ordination and integration of Community, National and Autonomous Region interventions. Moreover, the design of this policy has taken into consideration the classical conflict between equity and efficiency. The objective of this paper is to assess the results and the gradual changes in regional incentive policy applied in Spain over the last 15 years and to identify the elements in which public intervention could be improved in order to adapt this policy to the demands laid out within the new environment previously defined. This assessment includes: firstly, a brief analysis of the evolution of public intervention; secondly, a study of the spatial distribution of the incentives over the period considered; and thirdly, a comparison of the economic performance of the different areas depending on the awards received. The analysis of this policy is based on a database comprising over 16 000 items referring to award decisions to applications for Regional Investment Grants (Law 50/1985 of 22 December 1985) gathered from the Official State Bulletin (Boletín Oficial del Estado, BOE) during the period 1988-2003.

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
