Going Beyond Counting First Authors in Author Co-citation Analysis
The 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?
In 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
We 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
We 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

Forced Complete Femoral Approach for Urgent Thoracoabdominal Aneurysm Repair Using an Inner Branched Endograft
Background: A successful case of urgent type II thoracoabdominal aneurysm repair with an inner branched endograft conducted entirely through femoral accesses without the bailout possibility to achieve an upper extremity approach for bridging stents delivery is described. Case report: A 70-year-old male patient underwent hybrid treatment for a thoracic aortic aneurysm on complicated type B dissection in 2 steps. First, arch debranching with carotid-carotid-subclavian bypass and then ascending aortic replacement with reimplantation of the anonymous trunk plus TEVAR were performed. The scheduled 1-month control computed tomography angiography (CTA) showed a rapid increase of the false lumen thoracoabdominal aneurysm, with axial diameter measuring more than 10 cm. The repair procedure was based on the use, as off-the-shelf graft, of a prosthesis customized for another patient with inner branches for visceral vessels that well suited the characteristics of the case. A steerable guiding sheath was essential to stabilize the system in the selective and sequential cannulation of 2 of the 4 inner branches (for celiac trunk and superior mesenteric artery) and to complete the bridging stents deployment. Procedure was carried out without complications. Conclusions: In an urgent setting, total endovascular correction of a thoracoabdominal aortic aneurysm exclusively through femoral accesses appears to be feasible when the appropriate tools are available
