Representaciones de la mujer en Los que se van

La presente tesis plantea una investigación que se centra, sobre todo, en los personajes femeninos del libro Los que se van. Esta propuesta interpretativa busca renovar la metodología de la crítica tradicional merced a la atención que presta a los elementos ‘internos’ de la obra literaria (personajes, espacio, diálogos) para luego propender a una lectura asentada en el plano contextual o referencial. Se indaga en las posibles similitudes y diferencias que presentan sus formas de representar a la mujer y se realiza una interpretación de género. Su objetivo es comprobar que ciertos modelos patriarcales de representación de la mujer se mantiene en este volumen. Para ello, el trabajo se sirve de estudios como los de Benjamín Carrión, Agustín Cueva y Francisco Proaño Arandi, de concepciones sobre la mujer y el personaje literario femenino en las propuestas de Erich Neumann, Lucía Guerra‐Cunningham y Jorge O. Andrade y, de reflexiones narratológicas, principalmente de Algirdas Julius Greimas y de Mieke Bal. Por último, este trabajo se evidencia como una propuesta renovadora en la investigación y la crítica literarias.

Effects of two potential pest management components, intercropping and yellow sticky plastic sheet traps in two differentially resistant potato cultivars for the management of myzus persicae (Sulzer)

Polyculture is traditionally a low-input agricultural system and is important in many developing countries. Polycultures of interplanted crops often support fewer pests at lower densities than monoculture and tend to increase number of natural enemies. Also Yellow Sticky Plastic Sheet Traps have proved useful for trapping aphids. A field study was conducted to study the effectiveness of these potential pest management techniques along with the partially resistant (Cardinal) and susceptible (Desiree) potato cultivars, by using their different combinations for the management of Myzus persicae (Sulzer). Berseem, Trifolium alexandrinum (L.) (family: Leguminosae) was used for intercropping with potatoes. The different combinations (treatments) used in this study were: 1) Cardinal-berseem mixed cropping+yellow sticky plastic sheet traps 2) Cardinal-berseem mixed cropping 3) Cardinal+yellow sticky plastic sheet traps 4) Cardinal separately+berseem (as land area equivalents in relation to the mixed cropping treatments) 5) Cardinal (sole crop). Treatments 6-10 were the same treatments, but with Desiree as the potato cultivar. All these treatments were used to evaluate their effects as management techniques for M. persicae, their percent parasitism, percent emergence rate of the parasitoid, Aphidius matricariae Haliday and yield of Cardinal and Desiree. Mixed cropping of Cardinal and berseem together with the yellow sticky plastic sheet traps reduced aphids by over 90% compared with numbers on the sole Cardinal crop. This combination proved in this experiment the most effective for reducing the aphid populations as compared with all other treatments. Maximum percent parasitism i.e. 6.97 and 6.94% (almost double that in the other treatments) was recorded in the potato berseem mixed cropping, with and without traps respectively. In the same two treatments, yield was increased significantly as compared with all other treatments. However no significant effects of any of the variable was evident on the percent emergence of A. matricariae.

Antixenosis to the peach/potato aphid, myzus persicae (SuIzer) in potato cultivars

Field studies were conducted to determine the antixenotic resistance against the peach-potato aphid, Myzus persicae (Sulzer) in different potato cultivars i.e. Cardinal, Ultimus and Desiree. These cultivars were studied in the paired tests as Cardinal vs. Desiree and Cardinal vs. Desiree for antixenosis (systemic insecticide-based test). In Desiree vs. Ultimus, no significant difference was found for the preference of M. persicae, while in case of Cardinal vs. Desiree, there was a significant preference for Desiree. Cardinal clearly showed antixenosis to M. persicae.

Intonation abilities of children with Williams syndrome: a preliminary investigation

Purpose: The authors investigated expressive and receptive intonation abilities in children with Williams syndrome (WS) and the relation of these abilities to other linguistic abilities. Method: Fourteen children with WS, 14 typically developing children matched to the WS group for receptive language (LA), and 15 typically developing children matched to the WS group for chronological age (CA) were compared on a range of receptive and expressive intonation tasks from the Profiling Elements of Prosodic Systems-Child version (PEPS-C) battery. Results: The WS group performed similarly to the LA group on all intonation tasks apart from the long-item imitation task, on which the WS group scored significantly lower than the LA group. When compared with the CA group, the WS group was significantly poorer on all aspects of intonation. Whereas there were a number of significant correlations between the intonation and language measures in the control groups, in the WS group, there was only 1 significant correlation between a PEPS-C task and one of the language measures. Conclusion: As a result of this study, the authors concluded that children with WS have expressive and receptive intonation abilities as expected for their level of language comprehension and that intonation and other linguistic abilities in WS are not strongly related.
