Jagadiya Dam, River Khari, Kutch District (also spelt as Kachchh) Gujarat, India. Etymology. The species is named for Kutch District, Gujarat, from where the specimens were collected. Remarks. Caridina kutchi sp. nov. is distinguished by long, slender rostrum that is distinctly longer than antennal scale, the unarmed dorsal margin interrupted by a single tooth distally; pointed tip of rostrum with fine setae on the dorsal margin; telson posterior margin narrow and triangular with a median projection bearing intermediate spines of equal length that are distinctly shorter than the laterals. Caridina kutchi sp. nov. is similar to Caridina simoni Bouvier, 1904 which was described from Sri Lanka and now reported from South India (Richard and Clark 2014) in the structure of rostrum with pointed tip and the distal unarmed rostral margin interrupted by a single tooth distally. However, C. kutchi sp. nov. distinctly differs from C. simoni in telson structure. C. kutchi sp. nov. could be distinguished from C. simoni in having rostrum that is distinctly longer than antennal scale (vs. equal to or slightly longer than antennal scale in C. simoni); unarmed dorsal rostral margin interrupted by a single tooth distally (vs. unarmed dorsal rostral margin interrupted by 0–4 teeth in C. simoni); posterior margin of telson narrow and triangular with a median projection (vs. posterior margin of telson broad and rounded without a median projection in C. simoni); telson posterior margin bearing 2–3pairs of sparsely plumose intermediate spines of equal length and distinctly shorter than laterals spine (vs. 3–4 pairs of sparsely plumose intermediate spines either equal in length and slightly shorter than the laterals or the median pair longer and equal to laterals in C. simoni); preanal carina armed with a spine (vs. preanal carina unarmed in C. simoni). Caridina kutchi sp. nov. differs from C. babaulti, which is now reported from Gujarat, in possessing rostrum that is distinctly longer than antennal scale (vs. rostrum equal to antennular peduncle or shorter reaching middle of 3 rd antennular peduncle segment in C. babaulti); 12–22 teeth proximally leaving 0.5–0.65 of dorsal margin unarmed distally which is interrupted by a single tooth at distal end (vs. 14–25teeth proximally leaving 0.1–0.23 of dorsal margin unarmed distally in C. babaulti); 1–3 post orbital teeth present (vs. 3–7 postorbital teeth present in C. babaulti); 9–15 teeth proximally leaving 0.1–0.2 of ventral margin unarmed distally (vs. 3–8 teeth proximally leaving 0.1–0.45 of ventral margin unarmed distally in C. babaulti); carpus of first pereiopod with anterior excavation (vs. carpus of first pereiopod with deep anterior excavation in C. babaulti); telson posterior margin narrow and triangular, with a median projection (vs. telson posterior margin broad and rounded, with or without median protrusion in C. babaulti); 2–3 pairs of sparsely plumose intermediate spines of equal length and distinctly shorter than laterals (vs. 2–4 pairs or 5 sparsely plumose intermediate spines of varying length; fractionally longer or shorter than the lateral spines in C. babaulti); 8–12 uropod diaeresis spinules (vs. 12–21 uropod diaeresis spinules in C. babaulti); preanal carina armed with a spine (vs. preanal carina unarmed in C. babaulti). Caridina kutchi sp. nov. is the first Caridna species to be described from Kutch district, Gujarat state, which is known for its complex geological set up.Published as part of Pandya, Pranav J. & Richard, Jasmine, 2019, Report of Caridina babaulti Bouvier, 1918 (Crustacea: Decapoda: Caridea: Atyidae) and description of a new species Caridina kutchi sp. nov. from Gujarat, India, pp. 470-482 in Zootaxa 4568 (3) on pages 477-480, DOI: 10.11646/zootaxa.4568.3.3, http://zenodo.org/record/260166

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
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
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Contribution of Information and Communication Technology (ICT) in Country’S H-Index
No full textThe aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country’s scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect of these sub-indices on country’s H-index. To this purpose, required data for the panel of 14 Middle East countries over the period 1995 to 2009 is collected. Findings of the current study show that ICT development increases the H-index of the sample countries. The results also indicate that ICT Use and ICT Skill sub-indices positively contribute to higher H-index but the effect of ICT access on country’s H-index is not clear
Fully Turbulent Mean Velocity Profile for Purely Viscous non-Newtonian Fluids
No full textThe characteristic near wall behavior of turbulent flow of purely-viscous non-Newtonian fluids is discussed for both power-law (P.-L.) and Herschel-Bulkley (H.-B.) rheological models. A proper scaling is presented for H.-B. fluids to establish an analogy with power-law fluids with same flow index. To provide reference data for turbulent flow of non-Newtonian fluids, DNS simulations of power-law fluids are conducted in a rectangular channel for a large range of power-law indices ( = 0.5, 0.69, 0.75, 0.9, 1, 1.2). The DNS data show that the mean velocity profile in the viscous and logarithmic layers follow expressions of the form and respectively, where shows a logarithmic dependency on the flow index.Comparison with some experimental data shows the above formulation to be valid for Reynolds numbers (based on shear velocity) as high as 1000
After Belonging: Architecture, Nation, Difference
No full textThis book breaks new ground in demystifying the relationship between architecture, nationhood, and other forms of collective identity. It attempts to extricate the oppressive ideology of national identity entrenched within the very idea of architecture. Authors investigate themes such as cosmopolitanism, diaspora, geopolitics, globalisation, hybridity, and race. Certain chapters expose highly regulated environments which support cultural hegemony, such as the context of a hostel for ‘coloured colonial seamen’ in London, the illusionary rhetoric of ‘authenticity’ used to legitimise architectural conservation, and the role of the mosque as mediator between a post-war, multi-racial Britain, and ideas of nationhood. Others engage subjects at the urban scale, including the phenomena of universities transcending their nation-building roots to become agents of cosmopolitan urbanism, and how the discursive context of a high-profile yet unrealised modernist office-block in the City of London sustained a culture of British faux-nationalism. Remaining chapters adopt a postcolonial lens, with one examining how particular works of literary fiction reimagine notions of ‘place’ within an emerging intercultural nation, and another exploring the tense relationship between identitarian form and affective atmospheres to suggest the possibility of anti-essentialist experiences of architecture.
Together, these perspectives propose an alternative vision of the City, where neither state-sponsored identity politics nor right-wing populism determine the cultural context within which architects design for our collective urban experience. This book will be of interest to researchers and advanced students of Architecture, Anthropology, History, Human Geography, Politics, Sociology, and Urban Studies
