I testi del web: una proposta di classificazione sulla base del corpus PAISÀ
No full textIl presente contributo si propone di condividere le finalità, la metodologia di sviluppo e gli esiti delle prime ricerche condotte sul corpus PAISÀ, un corpus di testi in italiano contemporaneo scaricati dal web, ideato con finalità glottodidattiche e di ricerca nell'ambito del progetto omonimo. Presenteremo come il progetto si inserisce nel panorama, sempre più vasto, dei web-derived corpora, gli accorgimenti che sono risultati necessari in fase di creazione per evitare la spinosa questione del copyright e le ripercussioni che ciò ha avuto sui contenuti. Ci concentreremo poi sui diversi livelli di annotazione che arricchiscono il corpus PAISÀ, soffermandoci in particolare sullo sforzo di classificazione dei testi per argomento, intenzione comunicativa e genere testuale, tre parametri che, una volta trasformati in criteri di ricerca e esplorazione del corpus, permetteranno agli utenti - insegnanti di lingua in primis - una consultazione estremamente mirata e raffinata dei testi
Assessment of a natural dietary extract, titrated in phenylpropanoid glycosides, on blood parameters and plasma oxidative status in intensively reared Italian hares (Lepus corsicanus)
No full textTwo different doses of a natural extract titrated in phenylpropanoid glycosides (PPGs) were evaluated for their effect on blood parameters and plasma oxidative status in pairs of intensively reared Italian hares. The study lasted 210 days, during which 45 couples of hares were divided into three homogeneous groups. A control group (CON) was fed a control diet while the two experimental groups were fed a diet supplemented with 1 or 2 kg/t of a supplement titrated in PPGs. Blood samples were obtained at 0, 70, 140 and 210 days and assayed for plasma lipid profiles, bilirubin, haematological parameters and indicators of oxidative status (reactive oxygen metabolites (ROMs), thiobarbituric acid reactive substances (TBARS), vitamins A and E). Although dietary treatment did affect the levels of triglycerides, total cholesterol and total bilirubin, all of which decreased markedly (P < 0.05), while significantly increasing the (P < 0.01) HDL cholesterol values, it also significantly improved the oxidative status of the blood, which displayed an increase in both vitamin E (P < 0.01) and vitamin A (P < 0.05) and a decrease in ROMs (P < 0.01) and TBARS (P < 0.05). The improvements in the blood parameters, lipid profile and plasma oxidative status continued to increase significantly as the trial progressed, indicating a positive effect with increased length of treatment. The results of this study demonstrate an important role for feed supplementation with respect to antioxidant activity on some blood parameters, including the lipid profile and the oxidative status of blood
Effect of dietary extruded linseed, verbascoside and vitamin E supplements on selected serum biochemical parameters and plasma oxidative status in Lacaune ewes
No full textSelected serum biochemical parameters and plasma oxidative status were evaluated in Lacaune ewes on a diet supplemented with extruded linseed, verbascoside and vitamin E. A 98 day-trial was conducted on 44 ewes and started 40 ± 2 days post partum. The animals were divided into four homogeneous groups of eleven animals each; one control group (CON) with a basal diet, and the other three experimental groups supplemented with extruded linseed (L group), extruded linseedverbascoside (LVB group) and extruded linseed-verbascoside-vitamin E (LVBE group). All animals individually received an isoproteic and isoenergetic diet, consisting of 700g of concentrated feed and meadow hay ad libitum. Blood sampling of the ewes was performed three times: at the beginning (0 d), midway (49 d) and end of the trial (98 d). The following parameters were determined: triglycerides, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, bilirubin, alanine aminotransferase, aspartate aminotransferase, thiobarbituric acid reactive substances (TBARS), reactive oxygen metabolites (ROMs), vitamin A and vitamin E. Dietary integration in the LVB and LVBE groups resulted in an improvement in the blood profile, characterized by a significant (P=0.001) increase in HDL cholesterol and a marked decrease in triglycerides (P=0.001), total cholesterol (P=0.017), LDL cholesterol (P=0.001) and bilirubin (P=0.035), due to the verbascoside supplementation. In the same groups, there was an increase in blood vitamin A (P=0.002) and vitamin E (P=0.001), and a reduction (P=0.001) in ROMs and TBARS, with an improved plasma oxidative status. The dietary vitamin E integration did not produce a significant improvement in the parameters studied, with no statistical differences between LVB and LVBE groups. Animal feed containing extruded flaxseed, might therefore benefit from the addition of a verbascoside supplement, because of the positive effect showed by this molecule on the blood parameters
Effects of verbascoside on plasma oxidative status and blood and milk production parameters during the peripartum period in Lacaune ewes
No full textThis study examined the effect of administration of verbascoside on plasma oxidative status and on specific blood and milk production parameters in Lacaune ewes during the peripartum period. The trial, lasting 60. d, ran from 20. d before lambing until 40. d after and was conducted on 40 ewes in their 5th month of gestation. The animals were divided into two equal groups of 20: a control group CON, which did not receive food supplement, and the experimental group V, which received a supplement of verbascoside in their feed. Consumption of the supplement, which was 2. g/ewe/d, was assured by individual and daily administration of feed. The animals received a pellet feed concentrate at a rate of 400. g/ewe/d prepartum and 700. g/ewe/d postpartum. The ration was completed with mixed hay ad libitum. The experimental measures included body weight; blood samples 20. d before lambing and 0. d, 20. d and 40. d after lambing; body condition score; individual yield and quality of milk. The administration of verbascoside significantly improved milk yield by 9.3% (P< 0.01), significantly decreased triglycerides, total cholesterol, low-density lipoprotein cholesterol, alanine transferase (P< 0.01) and bilirubin (P< 0.05), and increased high density lipoprotein cholesterol (P< 0.01). Furthermore, the parameters of oxidative status in plasma were positively influenced by the use of dietary verbascoside, which resulted in significant decreases in reactive oxygen metabolites (P< 0.01) and thiobarbituric acid-reactive substances (P< 0.05) and increases in vitamins A and E (P< 0.01).The use of verbascoside during the peripartum period provided benefits on some blood parameters, oxidative status and milk production, particularly in the immediate postpartum period (0-20. d). © 2011 Elsevier B.V

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
