Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
The quality of fruits of different fruit species as a medium for the development of the Mediterranean fruit fly Ceratitis capitata wiedemann (diptera, tephritidae) under laboratory conditions : diploma thesis
No full textMediteranska voćna muha Ceratitis capitata Wied. (Diptera, Tephritidae) je štetnik koji se razvija u plodovima velikog broja voćnih vrsta. Cilj istraživanja koja su provedena u laboratorijskim uvjetima bio je utvrditi eventualne razlike u pogodnosti plodova odabranih voćnih vrsta na razvoj ličinki C. capitata. Plodnim ženkama C. capitata je dana mogućnost da u trajanju od 2 dana polažu jaja u plodove istraživanih domaćina u pojedinačnim kavezima. Istraživanja su pokazala da postoje razlike u elementima razvoja kod tri istraživana domaćina: grejp – Citrus paradisi Macfad., mango – Mangifera indica L. i jabuka – Malus domestica L. Prosječne vrijednosti trajanja razvoja ličinki u danima su najkraće u plodovima manga gdje prosječna dužina razvoja traje 15,35-21,1 dan, kod jabuke 31,7-36,1 a kod grejpa 30,6-41,3 dana. Najveći broj ličinki razvio se iz plodova manga (45-51 ličinki), zatim slijede plodovi jabuke (16-19 ličinki), a najmanji broj ličinki se razvio iz plodova grejpa (3-4 ličinke). Najveću težinu su imale kukuljice proizašle iz ličinki koje su se razvile iz plodova manga (8,7 g), a značajno manju iz plodova grejpa (5,5 g) i jabuke (4,8 g). Iz navedenog istraživanja možemo zaključiti da su plodovi manga najkvalitetniji medij za razvoj ličinki C. capitata.Mediterranean fruit fly Ceratitis capitata Wied. (Diptera, Tephritidae) is a pest that develops in the fruits of a large number of fruit species. Studies conducted under laboratory conditions were aimed at determining possible differences in the suitability of fruits of selected fruit species for C. capitata larval development. Fertile females of C. capitata were given the opportunity to lay eggs in individual cages for 2 days in the fruits of the hosts studied. The results showed that there are differences in the elements of development in the three hosts studied: grapefruit - Citrus paradisi Macfad., mango - Mangifera indica L. and apple - Malus domestica L. The average values of the duration of larval development in days are the shortest in mango fruits, where the average duration of development is 15.35-21.1 days, for apples 31.7-36.1 and for grapefruit 30.6-41.3 days. Most larvae developed from mango fruits (45-51 larvae), followed by apple fruits (16-19 larvae) and the fewest number of larvae developed from grapefruit fruits (3-4 larvae). Pupae from larvae developing from mango fruits (8.7 g) had the greatest weight, and significantly less weight from grapefruit (5.5 g) and apple (4.8 g). From the above studies, we can conclude that mango fruits are the best medium for the development of C. capitata larvae

Variations on the Author
Get PDF“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
Monosodium glutamate and its dietary role
No full textMononatrijev glutaminat natrijeva je sol glutaminske kiseline zaslužna za karakterističan
umami okus. Otkrio ju je Kikuane Ikeda 1908. godine u Japanu. U početku je korišten
pretežito u azijskim zemljama, mononatrijev glutaminat šezdesetih godina prošlog stoljeća
postaje jedan od najkontroverznijih pojačivača okusa. Smatralo ga se odgovornim za
simptome poput mučnine, osjećaja slabosti i utrnulosti koji su se javljali kod pojedinaca
nakon konzumacije kineske hrane. Prozvan je i ekscitotoksinom jer je uzrokovao stvaranje
lezija u mozgu uništavanjem neurona. Međutim, uočene su i pozitivne strane njegove
konzumacije kod određenih skupina ljudi. Dokazano je da MSG može poslužiti kao zdravija
zamjena za sol jer sadrži jednu trećinu natrija u usporedbi s natrijevim kloridom te može
potaknuti lučenje sline i tako poboljšati apetit kod starijih i bolesnih pojedinaca. Danas se
koristi kao pojačivač okusa u pekarskim i slanim trajnim proizvodima, umacima, juhama i
začinskim mješavinama, a sigurnost njegove konzumacije potvrđena je od strane
Međunarodnog odbora za aditive u hrani.Monosodium glutamate is the sodium salt of glutamic acid responsible for characteristic
umami taste. It was discovered by Kikuane Ikeda in 1908. in Japan. Used predominantly in
Asian countries, monosodium glutamate became one of the most controversial flavor
enhancers in the 1960s. Monosodium glutamate was thought to be responsible for symptoms
such as nausea, feelings of weakness and numbness that occurred in individuals after
consuming Chinese food. It is also called excitotoxin because it caused the formation of
lesions in the brain by destruction of neurons. However, positive aspects of its consumption in
certain groups of people have also been observed. MSG has been shown to serve as a
healthier salt substitute because it contains one-third sodium compared to sodium chloride.
Also, it can stimulate salivation and in that way improve appetite in elderly and sick
individuals. Today it is used as a flavor enhancer in bakery products, sauces, soups and spice
mixtures and the safety of its consumption has been confirmed by the International
Committee on Food Additives
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Get PDFWe 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
