Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Determination of aroma compounds of grafted and ungrafted Galia C8 melon cultivar in greenhouse growing
No full text10th EUCARPIA Meeting on Genetics and Breeding of Cucurbitaceae -- OCT 15-18, 2012 -- Antalya, TURKEYWOS: 000345687100058In this study, aroma compounds of grafted and ungrafted melon (Galia C-8) were investigated. Galia C-8 melon cultivar was grafted onto 7 different rootstocks [Benincasa hispida (BH), Cucurbita ficifolia (CF), Luffa cylindrical (LC), P 360, RS 841, TZ 148 (Cucurbita Hybrids) and Cucumis melo 'Kirkagac 637'(KA 637)]. Aroma compounds in ripening fruits of Galia C-8 melon were determined and 24 aroma compounds were identified by GS-MS (gas chromatography-mass spectrometry). It was found that 2- methylbuthyl acetate, Hexyl acetate and Octyl acetate were the major compounds in grafted and ungrafted Galia C-8 melon cultivar. However, ethyl hexanoate was strongly positively correlated with fruity and sweet taste and the highest content of ethyl hexanoate was determined from Galia C8 /RS 841 graft combination, while others were in trace amounts. Octyl acetate, isobuthyl acetate and butyl acetate contents of ungrafted melon fruits were higher than grafted melon fruits but 2-methyl butyl acetate content was similar both ungrafted and grafted melon fruits.European Assoc Res Plant Breeding, Cukurova Univ, Minis Food, Agr & Livestock, Turkish Sci & Technol Council, Antalya Tarim, Manier Seed, Yuksel Seed, Syngenta, AG Seed, Fito Seed, Multi Seed, Nunhems, Rijk Zwaan, Bati Akdeniz Agr Res Inst, Alata Hort Res StatCukurova UniversityCukurova UniversityThe authors thank to Research Found of Cukurova University for the financial support of this project.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Effects of NaCl application on physiological, morphological and pomological features of Sanliurfa summer squash genotypes
No full text10th EUCARPIA Meeting on Genetics and Breeding of Cucurbitaceae -- OCT 15-18, 2012 -- Antalya, TURKEYWOS: 000345687100112This research was conducted at GAP Agricultural Research Center of Turkish Ministry of Agriculture and Rural Affairs in Sanliurfa-Turkey between 2011 and 2012 in pots under non heated greenhouse condition to determine effects of salinity on eight Cucurbita pepo genotypes collected from different locations of Sanliurfa-Turkey. At the 4-5 true leaves, salt treatments were applied. Non salt plots continued from sowing to harvest as a control plot. Both quality and physiologic/vegetative characteristics were measured such as leaf temperature, leaf area, yield, TSSC, mean fruit weight, mean fruit height, fruit diameter and dry root weight/fresh root weight were tested at two years. Also final drought resistance tests were examined. The research had four salinity categories in order to determine salt effect on genotypes (50 mmol, 100 mmol, 150 mmol and the control at 0 mmol) were applied. Class A pan used for determining amount of water for irrigation. At the end of the experiment all genotypes died at 100 mmol and 150 mmolsalt. Applying 50 mmol salt injured most of genotypes except number 8 (Sanliurfa Mrkz.).European Assoc Res Plant Breeding, Cukurova Univ, Minis Food, Agr & Livestock, Turkish Sci & Technol Council, Antalya Tarim, Manier Seed, Yuksel Seed, Syngenta, AG Seed, Fito Seed, Multi Seed, Nunhems, Rijk Zwaan, Bati Akdeniz Agr Res Inst, Alata Hort Res StatGAP Agricultural Research Center of Turkish Ministry of Food, Agriculture and LivestockThe authors thank the GAP Agricultural Research Center of Turkish Ministry of Food, Agriculture and Livestock for financial support
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Determination of heterotic groups in summer squash (Cucurbita pepo L.) using morphological and molecular methods
No full text10th EUCARPIA Meeting on Genetics and Breeding of Cucurbitaceae -- OCT 15-18, 2012 -- Antalya, TURKEYWOS: 000345687100115Genetic distance of parental lines is crucial for heterosis breeding to be successful. Thus, it is important to do morphological and molecular characterization in order to determine differences and relationships of squash genotypes representing major gene pools. A total of 59 summer squash genotypes (Cucurbita pepo L.) were used in this study. The genotypes were both characterized for 83 morphological traits according to UPOV and for molecular markers via SRAP markers. Genetic relationship was determined using NTSYS2.1 statistical software based correlation matrix and unweighted pair group method arithmetic average (UPGMA). The morphological and molecular data were used for Principal Coordinate Analysis. The six main groups included 3, 1, 8, 33, 1 and 13 genotypes, respectively. Fifty nine summer squash genotypes were evaluated by SRAP markers. The 23 SRAP primer combinations generated 166 bands, 155 of which (92%) were polymorphic. The summer squash genotypes used in this study showed a high level of polymorphism for SRAP and phenotypic traits. Principle Coordinate analysis resulted with two major heterotic groups. Hybrid combinations have been made and will be tested for predictive value of morphological and molecular markers.European Assoc Res Plant Breeding, Cukurova Univ, Minis Food, Agr & Livestock, Turkish Sci & Technol Council, Antalya Tarim, Manier Seed, Yuksel Seed, Syngenta, AG Seed, Fito Seed, Multi Seed, Nunhems, Rijk Zwaan, Bati Akdeniz Agr Res Inst, Alata Hort Res Sta
