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
Slaughter yield, organ weight, abdominal fat, and consumer preference of noiler chicken on a diet with cashew kernel waste meal
No full textThe cashew nut industry produces cashew kernel waste meal (CKWM), a nutrient-rich by-product high in protein. CKWM has shown promise as a feed component for laying hens and broiler chickens. This study aimed at determining the slaughter yield, organ weight, abdominal fat, and consumer preference of noiler chicken on diets with cashew kernel waste meals. 270-day-old noiler chicks were randomly separated into five groups, with six replicates of 9 birds each. The treatment groups (W2, W3, W4, and W5) were fed diets with 5.0%, 10.0%, 15.0%, and 20.0% inclusion of cashew kernel waste meal, while the control group (W1) received a diet devoid of CKWM. The boilers were slaughtered on the 56th (last) day of the study, and their slaughter yield, organ weight, abdominal fat, and organoleptic attributes were assessed. The outcome revealed that the CKWM in the diets of noiler birds significantly affected (p < 0.05) their slaughter yield, organ weight, abdominal fat, and overall acceptability. Except for live weight, eviscerated weight, neck, and shank, the results of the slaughter yield showed significant differences (p < 0.05). All organ weights differ significantly (p < 0.05) except the pancreas. All the organoleptic properties except the overall acceptability were not influenced (p > 0.05). Comparing the results obtained with the different inclusion levels, diets with 5.0% CKWM inclusion had higher bled weight, dressing weight, drumstick, breast, and back weight, while up to 20.0% was tolerable for gizzard and spleen weight, abdominal fat, and acceptance. Thus 5.00% CKWM is recommended for improved slaughter yield and while up to 20.0% is acceptable for abdominal fat and consumer acceptance
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
Replacement value of cassava vinasse meal for maize on growth performance, haematological parameters and organoleptic properties of Japanese quails (Coturnix japonica)
Get PDFArticle Details: Received: 2018-10-01 | Accepted: 2018-10-22 | Available online: 2019-01-31https://doi.org/10.15414/afz.2019.22.01.7-12Two hundred and twenty eight (228) one day old quails were used to assess the suitability of cassava vinasse meal (CVM) as a replacement for maize at varying inclusion levels of 0.0%, 5.0%, 10.0% and 15.0%. The birds were fed an adequate starter diet for the first week before being randomly alloted into 4 dietary group of 3 replicate of 19 birds each. The feeding trial lasted for six weeks. The crude protein, crude fibre, ether extract, ash, moisture, nitrogen free extract and metabolizable energy of the dehydrated cassava vinasse were 19.26%, 7.96%, 3.72%, 9.33%, 5.68% and 12.17 MJ kg-1 ME respectively. The results showed that final weight, average daily weight gain and feed conversion ratio were significantly (P <0.05) influenced as inclusion level of cassava vinasse meal increases. Significant differences were observed on the haematological parameters such as haematocrit and mean corpuscular volume (P <0.05). The analyzed panelist response on organoleptic parameters showed that tenderness, juiciness and texture were significantly different (P <0.05) with birds fed 10.0% CVM having the least values. In conclusion, 10.0% CVM (21% replacement for maize) in the diet of quails had no deleterious effect on the feed conversion ratio, haematological parameters and meat acceptability. Moreover, further research could be geared towards the use of exogenous enzymes and the performance of other poultry species including broiler chicken.Keywords: blood, cassava, quail, sensory properties, vinasseReferencesABU, O.

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
