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
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

Description The shell is medium (SL 8.66 – 10.28 mm)ı thin and smoothı convex and sub-globosely depressed; apex is obtuse and depressedı shell surface has smooth lirae over the whole bodyı shell pale in colour and horny; body whorl broad and globsely rounded at periphery and whorl largeı about two-thirds of shell height and convexı slightly descending in frontı spire is low (SH 1.16 ± 0.01 mm); whorls 4 ¼ – 5; peristome simple and thinı aperture is broadly ovate-lunate in shape; howeverı the width of the aperture is greater than its height (AH 4.76 ± 0.28 mm and AW 5.02 ± 0.33 mm)ı columellar region is straight and reflected at the perforationı umbilicus of shell narrowly perforate. Radula Each row of the radula consists of 73 teeth with the formula 22-1-13-1-13-1-22 (36-1-36). Central tooth (c) triangular tricuspid with large mesoconus (m). Lateral teeth (lt) asymmetric tricuspid with very small ectoconus (ec) and larger endoconus (et). Rachidian tooth central cusp base width 10.19 µm and rachidian tooth central cusp height 29.49 µm (Figure 7a – g). Genital organ Atrium (at) very shortı penis (p) short and cylindrical and corresponding to penial verge (pv)ı length of penis 1.20 mmı epiphallus (e) long and slender tubeı double length of penisı epiphallic caecum (epc) having one coiled circle located at middle of epiphallus and attached with penial retractor muscle (prm). Flagellum (fl) slightly larger then penis lengthı with single fold. Vas deferens (vd) thin slender tube connected between distal end of epiphallus and free oviduct (fo). Vagina (v) smaller than penis in length (0.8 mm) and cylindrical in shape. Dart apparatus (da) 4 times as long as penisı stout and cylindrical in shape and attached to proximal end of vaginaı tip of da attached with dart retractor muscle (drm). Gametolytic sac (gs) prolonged and bulbousı around 1 mm in diameter. Gametolytic duct (gd) long (double penis length)ı stout and cylindrical in shapeı free oviduct (fo) as long as penis and a cylindrical tube. Oviduct (ov) with large lobulesı with prostate gland (pg) running alongside. Hermaphrodite duct (hd) coiled and approximately 5 mm in length (Figure 8). External features Animal about 4 – 5 mm in length with reticulated skinı the shell is pale yellowı with a large and globose body whorl. The body surface is dark chocolate brown in colourı while the tentacle is darker. The caudal horn is raised and same colour as the body. The posterior left dorsal lobe is short and slightly visible. The animal secretes a very light slime during locomotion. Distribution. The specimens were collected from 300 m north-east of the Pushpawati River (30.72573°Nı 079.59150°E) 3544 mı Chamoli Districtı Uttarakhandı Western Himalayaı India (Figures 4c – fı 5). Habitat. The new species was usually found more than 3500 m above sea level on the ground surface and on small bushes (vegetation) of Meconopsis aculeata and Aconitum sp. in the sub-alpine zone of the main valley. This species is probably endemic to this particular region and known only from the type locality (Figure 5). The species is mostly active during the monsoon and post-monsoon season. Etymology. The specific epithet ‘leggeae’ is named after Joan Margaret Leggeı Botanist of the Royal Botanical Gardensı Kewı who came to India to study flora of the Valley of Flowersı and lost her life there on 4 July 1939. Remarks. The new species M. leggeae sp. nov. is compared with M. nuda (Pfeifferı 1852) (Figure 2e). In M. nuda the shell is thickı larger and less globose and the spire is highı and the aperture is shortı while in the new species the shell is thin and sub-globoseı and the aperture is wider than long. Howeverı the height of the body whorl is greater than in M. nuda and the number of whorls is also fewer (4 ¼ – 5)ı whereas in M. nuda the whorl number is 5 – 5 ½. In M. vesicula (Bensonı 1838) the shell is larger in size (SL 13.05 ± 1.38 mm)ı whereas the ratio of the aperture height to shell height is also greater (4.48 mm). In M. glauca (Pfeifferı 1846) the shell is also large in size (SL 16.64 ± 3 mm)ı and the height to width ratio of the aperture is also less (0.93 mm) than in M. leggeae (0.95 mm). In comparison to M. kuluensis Blanfordı 1904 the shell length and width are also greater (SL 11.28 ± 2.02 mmı SW 8.41 ± 1.49 mm)ı and the aperture ratio is greater than in M. leggeae. In M. leggeae the diameter of the spire without the last whorl is also less than in all the compared species (4.80 ± 0.28 mm) (see Tables 1 and 2; Figure 2b – d). The unique large body whorlı aperture openingı and morphometric measurements are reliable characters to distinguish the species. Statistical species differentiation. For morphometric differentiation among five individuals of Macrochlamys leggeae sp. nov. (paratype NZSI M.31ı209/8ı n = 5) and five individuals each of the congeneric species M. vesicula ı M. glauca ı M. kuluensis and M. nuda (n = 5)ı a PCA was performedı using Past3. The variables SL/SW – shell length/shell widthı AH/AW – aperture height/aperture widthı AW/SH – aperture width/spire heightı HBW/AH – height of the body whorl/aperture heightı and HBW/SH – height of the body whorl/spire height were calculated. PC1 explained 93.7% of the total variance and PC2 explained 5% of the variance in th eshell ratio (Figure 6). The most significant variance was observed in the ratios AW/SH (0.822) and HBW/SH (0.567) which are significantly different from those of the closely related species (Tables 1 and 3; Figure 6).

Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

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
<b>Management of root knot nematode Meloidogyne incognita on tomato with botanicals</b>
No full text158-161A field
experiment was conducted for the management of Meloidogyne incognita infecting tomato
with five botanicals, viz. leaves of Calotropis gigantea (Linn.) R. Br. ex Ait. , Tagetes erecta Linn. and
Azadirachta indica A. Juss. ; seeds of Citrullus lanatus ( Thunb.) Matsumura & Nakai and Areca catechu Linn. Results showed statistically
significant increase in both seed germination as well as seedling establishment
in all the treatments when compared with control. Seed treatment with dry powder
of C. gigantea leaves gave the highest germination
(98.0%) and high percentage of established seedlings (99.6%). Root dip treatment
with leaf extract of C. gigantea resulted in significant reduction of
the soil nematode population at 45 days after transplanting and at harvest
(87.3% and 90.0%, respectively) and lowest
gall index (1.7) with increase in fruit yield, 23.9%
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
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
