Relationship of Body Weight and body Condition Score with health and milk production in Holstein Friesian and Simmental cows
No full textDairy cattle have traditionally been selected for their ability to produce milk and milk components. The traditional singleminded approach to selection of dairy cattle has now changed and functional traits have been included in selection indices by decreasing the emphasis on production. Some of the functional traits of importance in dairy cattle are discussed in this thesis: Body Weight, Body Condition Score and Muscularity.
The relationship of Body Weight and Body Weight Change with health disorders in early lactation in Holstein Freisian has been analyzed. Results of this study suggest that cows genetically inclined to have higher body weight and lower body weight loss in the early stages of lactation have less diseases. Daily body weights, therefore, should be the primary focus in early lactation because this is the period in which the majority of metabolic diseases occur.
The relationship of Body Condition Score and Muscularity with production traits has been analyzed in Italian Simmental cattle. A growth function for body condition score was also estimated. Results of this study suggest that selection for body condition score and muscularity in dual purpose breeds may be possible, and body condition score may be indirectly improve muscularity. Moreover, cows that address more of the energy ingested to the adipose and muscular tissues, are incline to have lower milk production.
The growth curve for body condition score may permit a comparison between expected and real body condition values and it may be useful both for the estimation of the Breeding Values of cows and in herd management
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
The genetic relationship of body weight and early-lactation health disorders in two experimental herds
No full textThe objectives of this study were to estimate genetic parameters for body weight (BW) and BW change (BWC) and genetic correlations of BW and BWC with diseases and genomic predicted transmitting abilities (PTA) of productive and conformation traits of Holsteins during the first 120 DIM
