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
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
A two-stage circumferential slot virtual impactor for bioaerosol concentration
No full textSlot virtual impactors provide an efficient low power method of concentrating
aerosols. A circumferential slot virtual impactor (CSVI) is especially effective because it
has a continuous slot, and, therefore, has no losses associated with the ends of the slot. A
CSVI can also fit a longer slot in a smaller footprint than a linear slot virtual impactor.
A two-stage circumferential slot virtual impactor system has been designed and
tested. The CSVI units are similar in principle to that tested by Haglund and McFarland
(2004). Specific geometric changes to the nozzle region were introduced based on the
numerical models of Hari (2005). The greatest change to the nozzle geometry of
Haglund and McFarland (2004) is the introduction of a radius on the accelerator nozzle.
The radius on the accelerator section allows larger particles to make a smoother transition
into the focused jet. The smoother transition reduces the amount of wall losses for larger
particles.
The geometric changes show a significant increase in the particle size range that
the virtual impactor can effectively concentrate. The extension of the dynamic range of
the improved geometry was evident in the results for both the 100 L/min first stage and
the 10 L/min second stage CSVI units. The two stages were tested individually and in
series where the nozzle Reynolds number was 250 for both units.The results of the experiments on the two stage CSVI system showed a peak
collection efficiency of 90%. The first and second stage had a Stokes cutpoint of 1.2,
corresponding to a particle size of about 2.
