Influence of keeping method (indoors vs. biotope) on the meat performance of goat kids of different genotypes - 1st communication: Body weight development and carcass quality
No full textTwenty pairs of twins of goat kids belonging to three different genotypes - Boer goat X German Alpine (F-1), F-1 x Cashmere (F-1 x K) and Cashmere (C) - were weaned at the age of 95,4 +/- 5,3 days and divided into two different husbandry systems One half of the kids stayed in the stable with intensive ad libitum feeding, the other half was sent to an infertile grassland pasture biotope for 77 days. At the age of 182,4 +/- 5,3 days this group was put into the stable for intensive finishing under housing conditions, too. At the age of 267,4 +/- 5,3 days all kids were slaughtered. For the whole investigation period the body-mass development of all kids was registered to find out their daily gain of weight. As carcass traits the dressing percentage and the amount of the high value parts back and hind quarter (with gigot) in the body were measured. Additionally, a visuable carcass judging was done. There was a striking influence of the husbandry system and of the breeding group on the investigated traits. The extensive-kept kids showed during the grazing period especially but also in the following fattening period, lower daily gains of weight than the permanentely intensive fed animals. For this, the final body-mass and the mass of the slaughtered body were lower for the extensive group. The dressing percentage was not influenced much by the keeping method while the amount of high value parts was significantly higher for the extensive-fed kids. This is especially due to a lower fat content of their bodies. Cashmere kids realised the lowest body masses and also showed significantly low quality of the slaughtered bodies
Influence of keeping method (indoors vs. biotope) on the meat performance of goat kids of different genotypes
No full textForty kids were divided to two different husbandry systems: One half stayed with intensive ad libitum feeding in the stable, the other half grazed an infertile grassland pasture biotope for 77 days and was then also fattened in the stable. At the age of 267,4 +/- 5,3 days all kids were slaughtered. To evaluate the chemical and physical attributes of the kid meat pH-value and conductibility were measured 45 min, and 24 h after slaughtering. Also dropping losses and sheer force were evaluated. Additionally, the fatty acid composition of subcutan-, kidney-, belly- and intramuscular fat was analysed. The chemical and physical investigations and also the analyses of fatty acid composition did not show a striking influence of the husbandry system or the breeding group on the kids' meat quality. Altogether, the meat quality is to be stated as good. Fatty acids causing tallowy taste were only found in amounts <3%. This should not be a problem in kid meat. The fatty acid CLA (18:2) was found in concentrations of 0,4-0,8% in all investigated fat locations

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
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
