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
The development and use of a cage-topper to enhance rat welfare
No full textThe welfare of rats used in scientific research is an important concern. A number of recent studies have demonstrated that larger and more complex housing provides a welfare benefit to rats over conventional cages. However, there are typically both practical and financial constraints to implementing this. We have developed a cage topper that can be added to a standard rat cage to provide additional space and complexity and that can be built in-house at a low cost. Here, we introduce the design of this cage topper and discuss its utility from the perspective of a researcher, a named animal care and welfare officer (NACWO)/lead technician, and a named veterinary surgeon (NVS). We conclude that while the cage topper is likely to provide a welfare benefit, more research is needed to assess if there are any adverse effects of the cage topper on animal health and biosecurity. At present, the cage topper may be most useful to enhance to welfare of rats who are healthy and would otherwise be housed in non-IVC conventional cages

"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.
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
A critical discussion about optimisation approaches for ocean energy array design
No full textAs the technology readiness level of ocean energy devices moves from single units to small arrays, evidence from related industries suggests the need for integrated array design tools. Those tools implement all the functionality required for assessing the economic performance, technical reliability and environmental impact of the diverse subsystems to be accounted for in the design chain. These include device hydrodynamics, design of the electrical connection to shore, moorings and foundations design, as well as logistic requirements for the installation and maintenance of the farm. This paper presents a critical discussion of approaches for optimising the solutions of such a tool when the target of the problem is to achieve the lowest Levelised Cost of Energy (LCOE) solution. Firstly, the problem is formally described, pointing out the complexity of the architecture of the models, the intervening variables and the constraints and boundary conditions of the solution space. Then, approaches for identification of lowest LCOE solutions are examined, starting from simplified one-parameter sensitivity analyses-such as, for example, interdistance among devices, and distance to shore-to more complex heuristic approaches. All the above considerations will be illustrated through examples pertinent to the ocean energy sector
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
