Curing Cholera: Pathogens, Places and Poverty in South Asia
No full textIn this paper I will seek to provide a new understanding of endemicity of disease in India. Through a study of cholera research in the twentieth century I will argue that disease and its endemicity has to be understood in biological factors as well as within a wider social and economic context. I will discuss the medical efforts at locating the causality of cholera from the nineteenth century in Indian climate, water bodies and human anatomy to show that cholera is no more a biological phenomena than water is an ecological or environmental problem. Both are essentially political and economic questions

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

Fig. 1 in Phylogeny and Biogeography of the Eleotrid Genus Hypseleotris (Teleostei: Gobioidei: Eleotridae), With Redescription of H. cyprinoides
No full textFig. 1. Strict consensus of 189 most parsimonious hypotheses of Hypseleotris relationships. The numbers at nodes are decay index values, and changes of selected morphological characters are indicated with hash marks and the character number and state change (characters are represented with DELTRAN optimization). The species name and collection locality are indicated, and clades discussed in the text are lettered. In the southeastern species, abbreviations after the name and locality indicate the province or drainage basin: East Coast (EC, also known as Eastern Province), Murray-Darling Basin (MDB, Murray-Darling Province), or Lake Eyre Basin (LEB, Central Australian Province).Published as part of Thacker, Christine & Unmack, Peter J., 2005, Phylogeny and Biogeography of the Eleotrid Genus Hypseleotris (Teleostei: Gobioidei: Eleotridae), With Redescription of H. cyprinoides, pp. 1-13 in Records of the Australian Museum 57 (1) on page 4, DOI: 10.3853/j.0067-1975.57.2005.1436, http://zenodo.org/record/575532
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
