Parents' guidance on TV use: a quantitative and qualitative model for content acquisition
Authors: Marta-Lazo Carmen 
Published: April 2019

Parents' behavioural patterns as regards TV use define children's interaction with the medium. Parents' supervision helps the child to establish a ser of personal criteria concerning both duration and frequency of exposure, as well as age appropriateness. Furthermore, as our research evinces, children in the habit of discussing TV shows with their parents reveal a higher degree of activeness in their visualisation process together with a notably finer ability of disclosing and decoding content in TV messages.
Las pautas que los padres ofrecen a sus hijos en cuanto a consumo televisivo son fundamentaies en la forma de interacción que el niño tenga con el medio. El control paterno ayuda al niño a aprender a establecer criterios relativos no sólo a la cantidad de exposición diaria, sino también en lo concerniente a los programas que resultan más o menos acordes para su edad. El estudio pone de manifiesto que los niños que acostumbran a dialogar con sus padres respecto a lo visto en televisión presentan mayores niveles de actividad en el proceso de visionado y saben interpretar con mayor claridad el contenido de los mensajes televisivos.
Magic ingredients and clinical tests in commercials as advertising strategies
Authors: Moreno-Castro Carolina 
Published: April 2019

In this paper we analyse several television commercials shown on Spanish national TV channels. There are two different kinds of advertising slogans to increase credibility of the advertised products: spots which make reference to nmagic ingredientsn, which are subject to trends and designed to make the target audience fantazise about the characteristics of these products; and secondly, we detect a growing number of advertisements which make reference to the product having been scientifically tested. However, complaints by consumers' organisations and the scientific community are on the rise concerning the abusive use of scientific terrninology on television advertising, as well as the lack of scientific reality of the claims made in the commercials.En este trabajo se analizan una serie de anuncios emitidos por las cadenas de televisión generalistas españolas en las que se emplean dos tipos de eslóganes publicitarios para intentar otorgar credibilidad a los productos que se publicitan. Por una parte, se encuentran anuncios que aluden constantemente a ingredientes mágicos que periódicamente se ponen de moda y que hacen que el imaginario colectivo fantasee sobre las características de estos productos; y por otra parte, se detecta que cada vez es mayor el número de anuncios que aluden a eslóganes en los que se hace constar que el producto ha sido comprobado científicamente o testado clínicamente por determinados laboratorios. Sin embargo, cada año aumentan las denuncias de colectivos de consumidores y de asociaciones médicas por el mal uso que se hace de la terminología científica en los anuncios publicitarios y por los mensajes que transmiten, que en la mayoría de los casos no se corresponden con la realidad científica.

Authors: Chaabi Youness , Lekdioui Khadija , Boumediane Mounia 
Published: April 2019

In this article we describe a new multi-agent approach for the accompaniment and follow-up of learners (tutoring) in collaborative social networks via network technologies. To assist learners in their collaborative learning process, the system we propose offers the possibility to identify the sociological behavioral’ profile of each learner on the basis of the automatic analysis of the asynchronous textual conversations exchanged between learners.
To achieve our aims, we first describe the sociological profiles that we use in our model. Then, we expose the approach used for the semantic analysis of the messages exchanged (full text), as well as the proposed indicators for the determination of these profiles. After, we present the results of the implementation of the system developed as part of an experiment that we conducted with the students of the Master Program “Software Quality” in the Ibn Tofail University of Kenitra, Morocco. We did indeed obtain very good performances during tests on corpora of messages.
Le regard du myope chez Jean Rouaud : un principe esthétique fondamental
Authors: Rus Anca 
Published: April 2019

En s’inscrivant dans la tradition littéraire française consacrée, notamment dans la lignée de Flaubert, le prosateur français contemporain Jean Rouaud considère qu’écrire est avant tout une question de point de vue, unique et propre à l’écrivain comme la vue raccourcie est propre au myope. Ce chapitre entend démontrer que la métaphore du regard du myope constitue chez Jean Rouaud un vrai principe esthétique qui unifie toute son œuvre. Plus exactement, le regard de l’écrivain, comme celui du myope, se déplace constamment entre le flou de la vue d’ensemble et la précision du détail. C’est à cette poétique que se rapporte notamment le symbole, important, des lunettes qui, associé au leitmotiv de la pluie, renvoie à l’« anamorphose » du réel que le regard créateur roualdien suppose.

Abstract
The high variation of the influenza virus hemagglutinin (HA), particularly of its immunodominant head epitopes, makes it necessary to reformulate seasonal influenza virus vaccines every year. Novel influenza virus vaccines that redirect the immune response toward conserved epitopes of the HA stalk domain should afford broad and durable protection. Sequential immunization with chimeric HAs (cHAs) that express the same conserved HA stalk and distinct exotic HA heads has been shown to elicit high levels of broadly cross-reactive Abs. In the current mouse immunization studies, we tested this strategy using inactivated split virion cHA influenza virus vaccines (IIV) without adjuvant or adjuvanted with AS01 or AS03 to measure the impact of adjuvant on the Ab response. The vaccines elicited high levels of cross-reactive Abs that showed activity in an Ab-dependent, cell-mediated cytotoxicity reporter assay and were protective in a mouse viral challenge model after serum transfer. In addition, T cell responses to adjuvanted IIV were compared with responses to a cHA-expressing live attenuated influenza virus vaccine (LAIV). A strong but transient induction of Ag-specific T cells was observed in the spleens of mice vaccinated with LAIV. Interestingly, IIV also induced T cells, which were successfully recalled upon viral challenge. Groups that received AS01-adjuvanted IIV or LAIV 4 wk before the challenge showed the lowest level of viral replication (i.e., the highest level of protection). These studies provide evidence that broadly cross-reactive Abs elicited by cHA vaccination demonstrate Fc-mediated activity. In addition, cHA vaccination induced Ag-specific cellular responses that can contribute to protection upon infection.

Published: April 2019

The objective of this work was to evaluate the thermal and biological treatment efficiency of anthracnose (Colletotrichum musae) in banana cv. 'Pacovan'. Three experiments were set up in the laboratory, the first "in vitro" to select the isolate of Trichoderma spp. which had greater mycelial inhibition on plaque, the 2nd "in vivo" was biological control using 2 races of Trichoderma spp. and the 3rd in vivo varying temperatures and exposure times of banana fruits contaminated with Colletotrichum musae. Positive treatments (using fungicide) and negative treatments were done with the application of distilled water only for experiment 2 and 3. The antagonistic biological control agents T2 and T9 were efficient in inhibiting the growth of Colletotrichum musae "in vitro", when analyzed "in vivo" did not have efficiency in the inhibition of the growth of the pathogen. Thermotherapy is a promising technique for the treatment of postharvest rot in banana fruits of 'Pacovan' cultivar, with the best efficiencies observed at 47ºC for 3 and 9 min, and 51º for 3 and 9 min.

Published: April 2019

Aims: Fig plants produce fruits in branches of the year, which grow after emission of buds from the leaf armpits. And the lopping system is one of the most common practices among the green fig farmers to increase production. Thus, the present work aimed to improve the physical, chemical and productive characteristics of fig trees in the semiarid region of Brazil.
Study Design: A complete randomized block design was used in a 3x2 factorial scheme (three pruning intensities: 5, 10 and 15 cm in length; and two lopping systems: with and without lopping), constituting six treatments with four replicates. Each experimental plot consisted of five plants, but only the three central plants were used.
Place and Duration of Study: The experiment was conducted in the didactic orchard of the Federal Rural University of Semiarid (UFERSA), Mossoró, RN.
Methodology: The treatments were: 5 cm pruning without lopping; 5 cm pruning with lopping; 10 cm pruning without lopping; 10 cm pruning with lopping; 15 cm pruning without lopping; 15 cm pruning with lopping. The following variables were analyzed: fruit weight (g), fruit length (cm), fruit diameter (cm), pulp firmness (N), soluble solids content (ºBrix), titratable acidity (%), vitamin C content (mg ascorbic acid 100 g-1 pulp), fruit yield (number of fruits plant-1 and kg plant-1). Data were submitted to analysis of variance by the F test at 5% probability and means were grouped using the Tukey test at 5% probability. The analysis was performed using R software version 3.5.2.
Conclusion: Pruning intensity 10 cm in length and the use of lopping system influenced the physical, chemical and productive characteristics of fig plants in the Brazilian semiarid region.

Published: April 2019

AbstractThe narrow‐ridged finless porpoiseNeophocaena asiaeorientalisis a small‐toothed whale with a coastal habitat and is sensitive to human activity. Aerial sighting surveys were conducted in 2012 to evaluate the abundance and distribution of the Sendai Bay‐Tokyo Bay population off the Pacific coast of eastern Japan. We flew along 35 east–west transects at intervals of 11.6 km over the study area between 34°57′ and 38°21’ N. In total, 25 groups were detected by two observers. The mean group size was 1.44 individuals. Porpoise abundance was estimated to be 1,491 individuals (coefficient of variation = 32.4%), which was lower than the abundance estimated in 2000 (ztest,p < 0.05). A population decline trend during 2000–2012 was also detected using four available abundance estimates (Bootstrapping linear regression,p = 0.040). A possible cause of this decline was coastal habitat disturbance and deaths by tsunami waves caused by the 2011 Great East Japan Earthquake. Density was as low as 0.221 individuals/km2, which is among the lowest levels in Japanese waters. Furthermore, distributional gaps reconfirmed by the present study and past genetic studies show that the population should be divided into at least two populations: northern (“Sendai Bay‐Fukushima”) and southern. Density decline was detected in the northern population between 2000 and 2012. Unlike the earthquake, human activities may continue to affect the porpoises. Viability analyses of these small populations should be conducted in the future.
