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
Production, Uses, and Ancestry of an Oilseed Crop, Perilla frutescens (L.) Britton var. frutescens in Japan: An Overview
Full text linkPerilla frutescens (L.) Britton var. frutescens has been cultivated as a traditional oilseed crop in Japan. Perilla seed oil was once used for industrial products such as fuel for lamps, waterproofing agent, and lacquered wares. Nowadays, it is commonly utilized to add flavor to cooking, and the seeds are also ground and powdered for use in traditional foods as flavoring. Perilla oil has recently received the attention of Japanese consumers because it is a good source of health benefit compounds including unsaturated fatty acids (e.g., α-linolenic acid) and bioactive flavonoids (e.g., luteolin). In the country, however, there has been little effort in improving the production potential of the crop through plant breeding. The present review
is an attempt to provide the current information about the production, uses and possible ancestry of P. frutescens var. frutescens in Japan. The paper also focuses on the problems and prospects of genetic improvement in this cro
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
Oljarice iz rodu Brassica na Japonskem
Full text linkBrassica oilseed crops are the third most important source of edible vegetative oils in the world. Among these crops, the cultivation history of B. rapa goes back to very ancient times in Japan. Its cultivation area expanded substantially in the 17th century and Brassica oil was used as fuel for lamps and cooking oil. Brassica napus L. ssp.napus was introduced into Japan mainly as an oil crop in the late 19th century, after which it gradually replaced the heirloom B. rapa L. ssp. oleifera (DC.) Metzg. cultivars used in the production of edible oil. The rapeseed (B. rapa and B. napus) cultivation area in Japan reached its peak in the 1950s and then decreased rapidly due to increase of imports of inexpensive oilseed crops. In recent years, however, domestic cultivation of B. napus has started to increase again. Japanese people consume rapeseed oil well and consider it to be a healthy oil with low levels of saturated fatty acids. This article aims to provide the information about the history, current state, problems, and prospects of rapeseed cultivation in Japan. The paper also describes an overview of agronomic characteristics of representative Japanese cultivars as well as cultural practices.Oljarice iz rodu Brassica so tretji najpomembnejši vir jedilnega rastlinskega olja v svetovnem merilu. Med njimi se je gojenje oljne repice (B. rapa) na Japponskem pričelo že v pradavnini. Površine njenega gojenja so se močno povečale v 17. stoletju, ko se je njeno olje uporabljalo kot gorivo za svetiljke in kuhanje. Oljna ogrščica (Brassica napus L. ssp. napus) je bila uvedena na Japonsko pretežno kot oljarica v poznem 19. stoletju in je nadomestila sorte oljne repice (B. rapa L.ssp. oleifera (DC.) Metzg.), ki so se uporabljale za pridelavo jedilnega olja. Površina gojenja obeh vrst je na Japonskem dosegla višek v petdesetih letih prejšnega stoletja in potem hitro upadla zaradi povečanega uvoza poceni jedilnega olja iz teh vrst. V zadnjih letih se domača pridelava oljne ogrščice spet povečuje, ker ga prebivalstvo rado uporablja kot zdravo jedilno olje z majhno vsebnostjo nasičenih maščobnih kislin. Namen članka je podati informacije o zgodovini, sedanjem stanju, problemih in bodočem gojenju oljne ogrščice na Japonskem. Članek daje tudi pregled agronomskih lastnosti japonskih sort kot tudi o načinih gojenja
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
