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
Coryphella verta Ev. Marcus 1970
No full text<i>Coryphella</i> cf. <i>verta</i> Ev. Marcus, 1970 <p>(Figures 6E, 7B)</p> <p> <b>Material examined</b>. Argentina, Río Negro: Plataforma, one specimen, 8 m, 21/02/2017 (ESCM-Ma-82); one specimen, 8 m, 01/02/2021 (ESCM-Ma-55); one specimen, 6 m, 17/08/2021 (ESCM-Ma-42).</p> <p> <b>Description</b>. Length up to 10 mm, body translucent white. A longitudinal dorsal thin white line runs from the oral tentacles to the posterior end of the foot. Conical rhinophores with fine wrinkles and white tip. Cerata cylindrical, bright orange-red with white tips. Cerata grouped in widely spaced clusters along the dorsum. The anterior group begins just behind the rhinophores and contains 8 to 11 cerata, arranged in rows with no more than four per row. There are four to six posterior groups on each side of the body with a decreasing number of cerata in each group, up to 11 in the former, as few as one in the posterior one. Oral tentacles thin, elongated and slightly flattened (Figure 6E). Radular formula is 21 x 1.1.1 (ESCM-Ma-82). Rachidian teeth with a narrow central cusp, slightly longer than the 5-8 denticles on each side. Lateral teeth with a broad base and 5-7 long denticles (Figure 7B).</p> <p> <b>Geographic distribution and depth range</b>. Recorded from Florida, Gulf of Mexico, Venezuela to southeastern Brazil (Millen & Hamann 2006). Found on rocky bottoms between four and 12 m depth. Here extended to San Matías gulf, Argentina.</p> <p> <b>Biology</b>. Found on hard bottoms associated with hydrozoans.</p> <p> <b>Remarks</b>. <i>Coryphella verta</i> is a tropical species distributed from Florida to Brazil (Millen & Hamman 2006) and is recorded here for the first time in the Argentine Sea. <i>C. verta</i> can be distinguished externally from <i>Flabellina dushia</i> because <i>F. dushia</i> has oral tentacles longer than rhinophores, shorter cerata grouped in arcs, a wider body and broad opaque white bands on the notum, sides, head, and distal parts of the rhinophores and oral tentacles. Internally the lateral teeth of <i>F. dushia</i> are more acute, the seminal receptacle is shorter and larger and has a conical penis with a pointed tip (Millen & Hamann 2006). Another tropical species is <i>F. dana</i>, which can be easily distinguished because it has annulate rhinophores (Millen & Hamann 2006). The identification here is provisional due to observed differences in the body color pattern.</p>Published as part of <i>Cetra, Nicolás & Roche, Andrea, 2023, Nudibranchia (Mollusca: Gastropoda) from San Matías Gulf, Northern Argentine Patagonia, pp. 455-473 in Zootaxa 5244 (5)</i> on page 467, DOI: 10.11646/zootaxa.5244.5.3, <a href="http://zenodo.org/record/7663830">http://zenodo.org/record/7663830</a>
"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.
Transient Expression of Reck Under Hepatic Ischemia/Reperfusion Conditions Is Associated with Mapk Signaling Pathways
No full textIn this study, we demonstrated the involvement of matrix metalloproteinases (MMPs) in hepatic ischemia/reperfusion (I/R) injury. Our aim is to evaluate the impact of reperfusion on I/R-related changes in RECK, an MMP modulator, and mitogen-activated protein kinase (MAPKs) pathways (ERK, p38, and JNK). Male Wistar rats were either subjected to 60 min partial-hepatic ischemia or sham-operated. After a 60 min or 120 min reperfusion, liver samples were collected for analysis of MMP-2 and MMP-9 by zymography and RECK, TIMP-1, and TIMP-2 content, MAPKs activation (ERK1/2, JNK1/2, and p38), as well as iNOS and eNOS by Western blot. Serum enzymes AST, ALT, and alkaline-phosphatase were quantified. A transitory decrease in hepatic RECK and TIMPs was associated with a transitory increase in both MMP-2 and MMP-9 activity and a robust activation of ERK1/2, JNK1/2, and p38 were detected at 60 min reperfusion. Hepatic expression of iNOS was maximally upregulated at 120 min reperfusion. An increase in eNOS was detected at 120 min reperfusion. I/R evoked significant hepatic injury in a time-dependent manner. These findings provide new insights into the underlying molecular mechanisms of reperfusion in inducing hepatic injury: a transitory decrease in RECK and TIMPs and increases in both MAPK and MMP activity suggest their role as triggering factors of the organ dysfunction
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.

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
