Phenotypic Assessments of Cattle and Buffalo through Body Linear Measurements and their Correlations
Get PDFBuffalo is an emerging species after cattle though they have some phenotypic difference. To assess differentiation between species based on body measurements a factorial experiment (2 species × 3 ages) of CRD conducted in Bangladesh. Live weight of buffalo (464.2 kg) differed (P < 0.001) with cattle (388.5 kg) and it increased (P < 0.001) with the increase of age. A significant difference (P < 0.01) was observed in the case of body condition score (BCS). The skin of buffalo was found thicker (P < 0.001) than cattle. Nine of the body measurements of buffalo (heart girth (HG), barrel (Ba), horn length (HL), horn circumference (HC), thigh circumference (ThC), hind shank circumference (HsC), fore shank circumference (FsC), hook to hook distance (HHD), and pin to pin distance (PPD) were higher (P < 0.001) than cattle. Wither height (WH), muzzle (Mz), tail circumference (TC), and hook to pin distance (HPD) differed (P < 0.01) between the species. Hip height (HH) differed significantly (P < 0.05). All the body parameters and skin thickness showed age effects. Live weights of the two species had a strong correlation with HG and Ba (0.79 and 0.74, respectively). HG showed strong correlation with Ba, HC, HsC and HHD (0.84, 0.72, 0.73 and 0.78, respectively). The correlation coefficient between WH and HH were 0.84, and HsC and FsC was 0.78. HL had strong correlation with HC, FsC and HHD (0.88, 0.71 and 0.79, respectively). So, various phenotypic traits were responsible for the change of other traits positively
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
Ranking of Four Types Fodder as Sole Diet Considering Biological Characteristics and Growth of Local Growing Bulls
No full textAims: In this experiment, evaluation of intake, digestibility and growth performances of local growing bulls by feeding Jumbo-green, Para and German grass based on Index (Mf) of Maize are considered and ranked this fodder accordingly.
Study Design: Completely randomized block design.
Place and Duration of Study: Bangladesh Livestock Research Institute (BLRI), Savar, Dhaka, between July 2016 and September 2016.
Methodology: Biomass production efficiency (Xddm), animal production efficiency (Xap), CH4 emission deduction efficiency (XCH4) and benefit to cost efficiency (Xbc) was considered to identify the biological characteristics of four fodders. Statistical analysis was done through SPSS-17 to evaluate the intake, digestibility and growth of animal. Rank of each fodder was calculated through the equation of Maize index (Mi) = (Xddm + Xap + XCH4 + Xbc)/4.
Results: Aggregation of four arithmetic average efficiency; Jumbo-green, Para and German got 0.42, 0.40 and 0.72 point out of 1.0 point of Mi, respectively. Among four fodders German grass performed best in terms of average daily gain (107 gm/d) and feed conversion ratio (46.9) compared to maize silage (64 gm/d & 58.4, respectively). Weight loss of bulls fed Jumbo and Para has occurred unexpectedly.
Conclusion: In combination of mathematical calculation and statistical evaluation, the rank of four fodders measured as Maize>German>Jumbo-green>Para
