Influence of genotype and soil on nutrients concentration of two Italian oat cultivars
No full textTotal phenols (TPs), total avenanthramides (AVNs; 2c+2p+2f), total antioxidant capacity (ORAC) and β-glucan were compared in two husked oat cultivars (cv.) grown in two different soils. Oat samples were labeled as: C1, cv. Donata in loamy soil; C2, cv. Donata in a medium texture soil; C3, cv. Flavia in loamy soil; C4, cv. Flavia in a medium texture soil.
In the dehulled grains: TPs values were influenced by the genotype only, as both Donata samples showed higher values than the two Flavia samples; total antioxidant capacity did not show any difference due to soil or genetic; total AVNs showed a significantly higher value only in C1 sample, with respect to C2 and C3, thus emphasizing differences due to soil type and cultivar, respectively; β-glucan did not show significant difference due to cultivar or soil.
The milling process significantly decreased TPs and ORAC values in all samples, but the reduction was higher in Donata than Flavia. Total AVNs were reduced by the milling process only in the Donata samples, whereas β-glucan did not show any reduction.
Overall, the soil type had a little impact on nutrients level of the analyzed samples, whereas the genotype had a remarkable role, primarily for antioxidants retention during the milling process

Oat germoplasm for food: quality characteristics in naked and husked cultivars
No full textOats nutritional characteristics for human consumption have been well described in many papers. Besides a high content of proteins and lipids, the presence of soluble fiber (β-glucans) and unique antioxidant molecules (avenanthramides) confer to oat kernel a high nutritional value, which could be exploited for the production of healthy foods. Thirty oat cultivars (both naked or husked) have been multiplied in 2014 and characterized for the content of β-glucan, soluble phenols (SPs), total avenanthramides (AVNs; 2c+2p+2f) and total antioxidant capacity (TAC).
SPs and TAC showed no significant differences between naked and husked samples. Average values of the 30 samples were the following: 1.12 ± 0.16 gGAE/Kg for SPs; 16.39 ± 1.77 mmolTE/Kg for ABTS and 6.74 ± 1.47 mmolTE/Kg for DPPH assay. A significant linear correlation was observed between SPs vs ABTS assay (R2 = 0.53) and SPs vs DPPH assay (R2 = 0.34) (p<0.05).
Total AVNs of naked oats were significantly higher than husked samples, with average values of 248.56 ± 194.01 and 84.87 ± 88.66 mg/Kg, respectively (p<0.05). A significant linear correlation was observed between SPs and total AVNs (R2 = 0.51; p = 0.0007) of all 30 samples.
In conclusion, as several cultivars, among the 30, have been released in recent years, these results indicate the importance of activating specific breeding programs to improve the nutritional and health protective characteristics of oats
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
