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

No full textSafe Minimum Standards in Dynamic Resource Problems—Conditions for Living on the Edge of Risk
No full textAbstract Safe Minimum Standards (SMSs) have been advocated as a policy rule for environmental problems where uncertainty about risks and consequences are thought to be profound. This paper explores the rationale for such a policy within a dynamic framework and derives conditions for when SMS can be summarily dismissed as a policy choice and for when SMS can be defended as an optimal policy based on standard economic criteria. We have determined that these conditions can be checked with quite limited information about damages and risks. In order to analyze the SMSs in a dynamic setting, we have developed a method for solving optimal control problems where the state space is divided into risky and non-risky subsets.safe minimum standards; optimal control; critical zone; threshold effects; mixed risk spaces
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
Implementing the Efficient Auction: Initial Results from the Lab
No full textThe efficient auction is designed to induce truthful bidding for bidders with affiliated values. Herein we implement the auction in the lab, and observe that inexperienced people can bid systematically in this more complex environment, albeit yielding a flatter bid function than the truthful.Key Words: auction, affiliation, experiments, valuation
Culture shaped by history : the Jewish community of Janina, Greece
No full textAnnette B. Fromm, Florida International University Professor of Museum Studies, delivers a talk entitled, "Culture Shaped by History: The Jewish Community of Janina, Greece." Using a slideshow, Fromm describes how Jews came to Janina, how they developed a unique, cultural enclave, and how the culture and practices have been preserved even as the Jews emigrated to the U.S. She discusses on weddings and other rituals which have survived in the New World and describes her family connections. Question and answer concludes the session. Fromm speaks at the 2013 Ada Finifter Memorial Lecture convened by MSU Librarian Deborah Margolis. Part of the MSU Libraries' Colloquia Series held at the MSU Main Library

The mod Margolis homology of the Dickson–Mùi algebra
No full textLet be regarded as the translation group on itself. It is considered as a subgroup of the symmetric group on letters. We completely compute the mod Margolis homology of the Dickson–Mùi algebra, i.e. the homology of the image of the restriction with the differential to be the Milnor operation , for an odd prime and for any , . The motivation for this problem is that, the Margolis homology of the Dickson–Mùi algebra plays a key role in study of the Morava K-theory of the symmetric group on letters. The main tool of our work is the notion of “critical” elements. The mod Margolis homology of the Dickson–Mùi algebra concentrates on even degrees. It is analogous to the mod Margolis homology of the Dickson algebra
