Oral history interview with Robert Sandmeyer
No full textRobert Sandmeyer completed his graduate work at Oklahoma State University's College of Business Administration, now Spears School of Business, receiving his doctorate in 1962. He discusses how he then joined the faculty ranks at OSU and began his research and teaching career. Sandmeyer, dean of the college 1977-1994, talks about focusing on improving opportunities for faculty and students alike, serving as the first director of the Office of Research and Economic Development, and building community partnerships. He also describes some of the developments in the program, new directions, endowed chairs, and student success efforts.The O-STATE Stories Oral History collection is comprised of interviews which chronicle the rich history, heritage, and traditions of Oklahoma State University
The Trifluoromethylating Sandmeyer Reaction: a method for transforming C[BOND]N into C[BOND]CF3
No full textA means to trifluoromethylate: The beneficial properties imparted by the trifluoromethylation of aromatic compounds continue to drive the discovery of novel reagents and reactions for the late-stage introduction of such moieties. Highlighted here is the recently discovered Sandmeyer trifluoromethylation approach, which now permits aromatic amines to be substrates in a direct trifluoromethylation strategy

Characterization of a transpositionally active Ty3 element and identification of the Ty3 integrase protein.
No full textTy3 is a Saccharomyces cerevisiae retrotransposon associated with tRNA genes. Two Ty3 elements have been cloned and characterized. The complete nucleotide sequence for one element, Ty3-2, was reported previously (L. J. Hansen, D. L. Chalker, and S. B. Sandmeyer, Mol. Cell. Biol. 9:5245-5256, 1988). However, this element is incapable of autonomous transposition. The complete DNA sequence of a transpositionally competent Ty3 element, Ty3-1, is presented here. Its sequence translates into two overlapping open reading frames, TYA3-1 and TYB3-1, which encode proteins with homology to the proteins specified by the retroviral gag and pol genes, respectively. Comparison of the Ty3-1 nucleotide sequence to Ty3-2 suggests that the TYB3-2 open reading frame of Ty3-2 is truncated by the deletion of a single nucleotide, which causes a frameshift mutation. Restoration of the reading frame with insertion of a single adenine by site-directed mutagenesis converted Ty3-2 into a transpositionally active element, Ty3-2(+ A). Western blot analysis with antibodies made against synthetic peptides identified integrase (IN) proteins in viruslike particle preparations from cells expressing Ty3 elements. Cells expressing Ty3-1 and Ty3-2 (+A) produce antibody-reactive proteins with approximate molecular masses of 61 and 58 kilodaltons (kDa), while cells expressing Ty3-2 produce reactive proteins of approximately 52 and 49 kDa. Together, these data show that the 61- or 58-kDa protein, or both, provides the integrase function of Ty3
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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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

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
