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
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
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
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
Biodiversity on collectors of shellfish larves at selected locations
No full textU ovom radu prikazano je istraživanje zajednice školjkaša na kolektorima ličinki školjkaša koji su postavljeni na dva područja ekološke mreže Natura 2000, Pantan (HR3000430) i ušće Cetine (HR3000126). Kolektori su postavljeni u svrhu prikupljanja ličinki endemske, dugoživuće, kritično ugrožene i strogo zaštićene vrste školjkaša u Mediteranu, periske Pinna nobilis, Linnaeus 1758 te prikupljanja podataka o biološkoj raznolikosti školjkaša na kolektorima. Tijekom analize obraštajne zajednice s kolektora ličinki školjkaša determinirano je ukupno 19 vrsta školjkaša iz 11 porodica. Tijekom obrade kolektora nisu pronađene juvenilne jedinke vrste P. nobilis, ali determinirana je invazivna vrsta mješčićnice Styela plicata za koju postoje indicije da je rezervoar parazita Haplosporidium pinnae koji je detektiran kao uzročnik masovne smrtnosti vrste P. nobilis.The paper presents a study of the shellfish community on shellfish larvae collectors set up in two areas of ecological network Natura 2000, Pantan (HR3000430) and the Cetina estuary (HR3000126). The collectors were set up with purpose to collect the larvae of endemic, long-lived, critically endangered and strictly protected species in the Mediterranean Pinna nobilis, Linnaeus 1758, and to collect data on the biological diversity of bivalves on collectors. Analysis of the shellfish larvae collectors resulted in determination of 19 species from 11 families. During collector processing none of the P. nobilis juveniles were found, but the invasive species Styela plicata was determined for which there are indications of being reservoir of the Haplosporidium pinnae parasite which is detected as probable cause of P. nobilis mass mortality
Shellfish farming along the eastern Adriatic coast
No full textUzgoj školjkaša uz istočnu obalu Jadrana temeljen je na višestoljetnoj tradiciji koja se do danas nije puno mijenjala. U radu je posebna pažnja usmjerena na opisu tradicionalnih metoda uzgoja najzastupljenijih vrsta školjkaša, dagnje i kamenice. U radu je naglasak na lokacije gdje se školjkaši uzgajaju već dugi niz godina, Malostonski zaljev i Limski kanal. Hrvatsko školjkarstvo ima velike potencijale za daljnji razvoj, zbog kvalitete mora i mnogobrojnih lokacija koje su pogodne za uzgoj. Proizvedene količine dagnje i kamenice ne zadovoljavaju domaću potražnju na tržištu koja se rapidno povećava za vrijeme turističke sezone. Naime, ulaganjem u ovaj sektor koji je rastući u svijetu zbog sve veće potražnje za morskim organizmima povećat će se proizvodnja koja će dovesti do izvoza i pozitivne vanjskotrgovinske bilance.Shellfish farming along the eastern Adriatic coast is based on a centuries-old tradition that has not changed much to this day. The paper gives special attention to the description of traditional methods of growing the most common species of shellfish, mussels and oysters. In this paper, locations where shellfish have been farmed for many years, the Mali Ston Bay and the Lim Channel, are emphasized. Croatian shellfish farming has great potential for further development, due to the quality of the sea and numerous locations that are suitable for breeding. The quantities of mussels and oysters produced do not meet the domestic demand on the market, which is rapidly increasing during the tourist season. Namely, investing in this sector, which is growing in the world due to the growing demand for marine organisms, will increase production, which will lead to exports and a positive foreign trade balance
