Richard Dorson (interview)
No full textThis interview is included in the American Folklore Society Oral History Project held at the Archive of Folk Culture, American Folklife Center, Library of Congress, Washington, D.C. In this item, Richard M. Dorson is interviewed by Richard Reuss at the American Folklore Society annual meeting in Nashville, Tennessee for the American Folklore Society Oral History Project. Biography/History note: Richard M. Dorson, folklorist, author, and educator, was born in New York City in 1916 and died in 1981. He earned his B.A., M.A. and Ph.D. at Harvard University and taught at Harvard and Michigan State University before becoming professor of history and folklore at Indiana University where he founded its Folklore Institute in 1963 and became the first director and first chair of the Folklore Department at Indiana University in 1978. This collection consists of 1 sound tape reel (40 min.) : analog, 7 1/2 ips, 2 track, mono. ; 7 in. It was originally recorded on November 2, 1973 at the American Folklore Society annual meeting in Nashville, Tennessee by Richard Reuss on a Sony audiocassette. This is a first-generation copy

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
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

Superradiant instability of black holes immersed in a magnetic field
No full textMagnetic fields surrounding spinning black holes can confine radiation and trigger superradiant instabilities. To investigate this effect, we perform the first fully-consistent linear analysis of the Ernst spacetime, an exact solution of the Einstein--Maxwell equations describing a black hole immersed in a uniform magnetic field B. In the limit in which the black-hole mass vanishes, the background reduces to the marginally stable Melvin spacetime. The presence of an event horizon introduces a small dissipative term, resulting in a set of long-lived -- or unstable -- modes. We provide a simple interpretation of the mode spectrum in terms of a small perfect absorber immersed in a confining box of size ∼1/B and show that rotation triggers a superradiant instability. By studying scalar perturbations of a magnetized Kerr--Newman black hole, we are able to confirm and quantify the details of this instability. The instability time scale can be orders of magnitude shorter than that associated to massive bosonic fields. The instability extracts angular momentum from the event horizon, competing against accretion. This implies that strong magnetic fields set an upper bound on the black-hole spin. Conversely, observations of highly-spinning massive black holes impose an intrinsic limit to the strength of the surrounding magnetic field. We discuss the astrophysical implications of our results and the limitations of the Ernst spacetime to describe realistic astrophysical configurations
