Interview with James F. Bonner
No full textInterview in 1980 with professor of biology James Bonner begins with his recollections of growing up in an academic family. In 1929, his father, a physical chemist at the University of Utah, was a visitor at Caltech, where Bonner enrolled as a junior. Recalls course work with X-ray crystallographer Roscoe G. Dickinson and activities of Division of Chemistry and Chemical Engineering under Arthur Amos Noyes; humanities courses with William B. Munro; physics with Earnest Watson, William V. Houston, and Carl Anderson; geology with John P. Buwalda; and biology with Thomas Hunt Morgan, Henry Borsook, and Theodosius Dobzhansky. Became Dobzhansky's summer researcher and editor; switched from chemistry to biology. Graduate work with Dobzhansky on Drosophila genetics and Kenneth Thimann on plant hormone auxin. Friendship with Noyes. NRC postdoctoral fellowship to Utrecht, Leiden, and ETH, 1934-35. Joined Caltech's Biology Division in 1936 as an instructor: recalls colleagues Frits Went, Arie J. Haagen-Smit, Johannes van Overbeek; plant labs at Caltech; coining of term phytotron. Recollections of Robert A. Millikan. War work for U.S. Emergency Rubber Project on guayule and Cryptostegia. Work on cell biology with Sam Wildman; discovery of Fraction 1, central enzyme of photosynthesis. Founding of Caltech's Industrial Associates program in 1950. Recalls graduate student Paul Tso, discovery of plant actomycin, isolation of ribosomes. Work of Robert Holley on transfer RNAs. Consultant to Malaysian rubber industry. "Next 100 Years" project, with Harrison Brown. Studies RNA in 1960s with R. C. Huang and histone chemistry with Douglas Fambrough. Visitor at Oxford, 1963. Remarks on underdeveloped countries. Study of population growth with H. Brown. Comments on his recent work on cloning genes, and visits to Singapore and China. His hopes for genetic engineering. Stint as acting chairman of the Biology Division; comments on Robert L. Sinsheimer. [See also 1978 joint interview with Bonner, N. H. Horowitz, D. F. Poulson, and S. H. Emerson.

Double-clad structures and proximity coupling for diode-bar-pumped planar waveguide lasers
No full textWe report, for the first time, fabrication of double-clad planar waveguide structures and their use for multiwatt, diode-bar-pumped, planar waveguide lasers based on Nd3+ and Yb3+-doped YAG. The direct-bonded, five-layer structures of sapphire, YAG, and rare-earth-doped YAG have sufficient numerical aperture to capture the fast-axis divergence of a diode bar by proximity coupling with no intervening optics, leading to very simple and compact devices. The restriction of the doped region to the central core leads to diffraction-limited laser output in the guided direction. We also show that the direct-bonding fabrication process can lead to a linearly polarized output

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
Nephrology-specific clinical performance indicators for nurse practitioner education in Australia: A resource for students and clinical support team members
No full textFour years ago, we published the first edition of Nephrology specific clinical performance indicators for nurse practitioner education in Australia (Douglas & Bonner, 2017). As of January 2021, the document had been downloaded 687 times, with 156 downloads in the previous six months. This metric, along with informal feedback, demonstrated that the document was a valued resource.Full Tex
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
