Effects of extruded linseed dietary supplementation on milk yield, milk quality and lipid metabolism of dairy cows
No full textTwenty Italian Friesian dairy cows were used in an experimental trial to study the effects ofextruded linseed dietary supplementation on milk production, milk quality and fatty acid (FA) percentages of milkfat and total plasma lipids and plasma phospholipids. Control cows were fed a corn silage based total mixed ration(TMR) while treated animals also received 700g/head/d of extruded linseed supplementation. Feed intake was similarbetween groups. Milk yields was tendentially greater for cows fed extruded linseed. Milk urea content (P<0.05)were reduced by treatment. Results showed a significant increase n-3 FA concentration (particularly alpha linolenicacid) and a significant reduction of n-6/n-3 FA ratio in milk fat, total plasma lipids and plasma phospholipids(P<0.001); moreover a reduction trend (P<0.1) of arachidonic acid concentrations was observed in milk fat, totalplasma lipids and plasma phospholipids. At last, treatment enhanced milk fat conjugated linoleic acid (CLA) percentage(P<0.05).[...

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
