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

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

Application of the MONERIS model in the Lake Naivasha catchment, Kenya
No full textThe Lake Naivasha ecosystem is important in Kenya but it seems to be under pressure because of the economic activities like agriculture, water abstraction, geothermal power generation, keeping domestic animals, fishing and also tourism. However there is a concern that the Lake is continuously under the threat of cultural eutrophication. Questions have been raised as to what roles the Rivers Malewa and Gilgil play into the input of nutrients into the lake. This study seeks to assess the N and P situation in the Malewa and Gilgil Rivers. Establish the applicability of the MONERIS model in the catchment in order to know the contribution of Malewa and Gilgil Rivers to the input of nutrients loads particularly nitrates and phosphates into the Lake and identify the most important pathways for the river runoff and the nutrients emission and whether anthropogenic sources play a role. This study found that the mean value for nutrient concentrations of the Malewa River were NO31.982 mg/l, NH40.201 mg/l, NO20 mg/l, DIN 2.184 mg/l, TN 10.696 mg/l, SRP 0.035 mg/l andTP 0.123 while for the Gilgil River NO32.091 mg/l, NH40.259 mg/l, NO20.001 mg/l, DIN 2.35 mg/l, TN 11.025 mg/l, SRP 0.031 mg/l and TP 0.105 mg/l. The discharge was found to vary within the sub catchments. The River flow within the catchment is dependent on base flow/ground water which contribute up to 250 mm/yr. The average loads produced by the nine sub catchments include 237t/yr DIN, 256t/yr TN and 6t/yr for TP. The Malewa River sub catchments were found to contribute the higher loads compared to the Gilgil River sub catchments. The most important emission pathways for N was found to be the ground water which transports up to 11kg N/(ha*yr) while for phosphorus, urban and surface runoff were the most important transporting up to 0.18 kg P/(ha*yr) and 0.1 kg P/(ha*yr) respectively. In both the TN and TP loads anthropogenic sources played a huge role
