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
A naturalistic study of the measurement of seizure adequacy in electroconvulsive therapy
No full textObjectiveThe aim of this study was to assess an electroconvulsive therapy (ECT) rating scale by studying the intraictal electroencephalograph parameters induced by the seizure, and determine the clinical utility of such a scale in terms of time, application and ease of use.MethodThis naturalistic study of 55 depressed patients over a 2-year period examined specific parameters of the intraictal electroencephalograph seizure morphology and computer printout, and their association with overall clinical outcome. The rating scale was developed and evaluated in terms of clinical reliability and ease of use.ResultsOverall, 1076 individual ECT treatments were given. Using multiple regression analysis, overall seizure adequacy correlated most closely with abrupt seizure endpoint, a high amplitude rhythmic spike and wave phase of >13 s, a seizure energy index of >1000 u, and an electroencephalograph seizure length of > 24 s. "Adequate" overall ratings as determined by the rating scale were shown to correlate significantly with overall clinical improvement. The rating scale had extremely high interrater and test-retest reliability; and was relatively easy to use and time efficient.ConclusionsThe use of the rating scale has the potential to help clinicians optimize ECT. While not perfect in any sense, it still gives clinicians good predictive qualities when used as a clinical guide. It is important that larger studies look at all the potential variables that may interact with seizure adequacy and clinical outcome.Edwards, Mark; Koopowitz, Leslie F.; Harvey, Eileen J
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

An interdisciplinary course for trainee psychiatrists: feedback and implications
No full textThe definitive version is available at www.blackwell-synergy.comObjective: To describe a course for trainee psychiatrists, designed to encourage critical thinking within an interdisciplinary framework. Trainees’ responses to the course, and the implications of these for teaching, learning and clinical practice, are considered. Method: Trainees were interviewed, and their responses subjected to content analysis. Results: To some extent, the course appears to have met its objectives. However, some trainees found parts of the course content threatening, and reported negative perceptions of teaching staff and the process of critical appraisal. Conclusions: Challenging taken for granted beliefs in psychiatry is a fundamental skill, which should be fostered in trainee psychiatrists if the profession is to move forwards as an intellectual and clinical discipline. The lessons learned from the course we describe may be useful to others who wish to pursue integrated, interdisciplinary teaching methods.Anna Chur-Hansen, Leslie Koopowitz, Jon Jureidini, Sotoodeh Abhary and Steve McLea
