The Effect of High Quality Feed Supplement on Growth Performance Post-Weaning Calves
Full text linkThis research aimed to evaluate the effect of high quality feed supplement (HQFS) in growth performance of post-weaning calves. Twenty four calves post-weaning aged 6 months old, consisting of 12 males and 12 females, randomly divided into 2 groups, each group consisting of 6 calves. Grouping male and female calves fed control feed plus HQFS, was formulated from corn grain, corn gluten meal (CGM), pollard, soybean meal (SBM), wheat flour and agromix booster (treatment diet) as first group (treatment), and the second group was fed control feed without addition of HQFS (control). This study was conducted for 6 weeks. The variables observed included feed intake (dry matter, crude protein, and TDN), weight gain, feed conversion, feed cost per gain and body size (body length, chest girth, and withers height). The treatment was in factorial 2x2 in a Completely Randomized Design (CRD). Growth performance of post weaning calves were analyzed as repeated measures with feed (treatment and control) and sex (male and female) as factors. Results showed that the CP consumption, ADG and chest girth of treatment group was higher than (P<0.01) than the control group (0.42 and 0.34 kg/d, 0.95 and 0.71 kg/d, and 12.41 and 8.25 cm). TDN consumption, feed conversion, and body length of the treatment group were higher (P<0.05) than the control group (3.08 and 2.57 kg/d, 3.64 and 4.86, and 8.12 and 5.95 cm). DM consumption, chest girth and feed cost per gain of treatment and control group were not significant (3.87 and 3.69 kg/d, 7.30 and 6.72 cm, and IDR 16,280.00 and IDR 19,167.00). There was no difference between the growth of post-weaning calves between the male and female groups. There was no interaction between feed type and sex of the post-weaning calves. The conclusion of this study was that post-weaning calves fed HQFS (20.2%) produced better growth performance than controls

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
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
