Effect of enrichment with live insect larvae (Hermetia illucens) on egg quality in laying hens
No full textInsects can promote sustainable livestock farming being an environmentally friendly feed with a rich nutritional profile which may enhance livestock health and welfare to varying degrees, depending on the type of product used (e.g., protein meal, fat, live or dried larvae). In this context, the present study evaluated the effects of the supplementation (as an enrichment) over the diet with live larvae of Hermetia illucens (HI) on egg chemical composition, fatty acid profile, and sensory characteristics. To this purpose, laying hens from two genotypes (Novogen Brown and Novogen White) were randomly allocated to 8 pens of a multi-tier system and fed a corn-soybean meal-based diet. From 36 to 40 weeks of age, half of the pens received live HI larvae (supplementing 10% of the daily feed intake) offered in two circular feeders per pen, once daily. After 35 days of enrichment, a total of 400 eggs (50 per pen; 4 pens with and 4 without enrichment) were collected. Data were submitted to ANOVA with HI enrichment and genotype with interaction as fixed effects and the pen as a random effect, using the PROC GLIMMIX of SAS. The HI enrichment did not affect most of egg rheological and physical traits (p>0.05), whereas it decreased shell percentage (9.75% vs. 9.93%; p=0.017) and albumen pH (8.90 vs. 8.97; p=0.065) in comparison with the control group. Albumen protein content was lower in the eggs from the enriched hens compared to those of the control group (10.5% vs 10.9; p=0.019). In the yolk, the rates of C14:0 (+159%; p<0.001), minor SFAs and MUFAs, and conjugated linoleic acid (C18:2 trans 9-11) (+12%; p<0.001) were higher in eggs from enriched hens compared to eggs of the control group. As for the sensorial evaluation, a triangular test revealed no significant differences between the eggs of the two feeding treatments. In conclusion, the enrichment with live HI larvae at 10% of feed intake did not impair egg nutritional or sensory quality and may promote animal welfare by favouring natural foraging behaviours

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
