Acción colectiva rural, reforma agraria y política en El Ecuador, ca. 1920-1965

This thesis studies the rural collective action processes between 1920 and 1965 in Ecuador with a social history and political sociology approach. An approximation is carried out towards the conflicts, mobilizations and protests where indigenous and not indigenous peasants participated. Because of this, they are considered two periods, the first one that last from 1931 to 1947, sealed by the political instability and a constant change of governments; and the second one between 1948 and 1965, in a phase of successive constitutionally governments that ruled between 1948 and 1960. The conflicts and rural mobilizations reached a major visibility since 1958, deeply affecting the public opinion. The importance and magnitude of the rural mobilizations between 1959 and 1963 generated a controversy on their political effects in the agrarian change. Certainly, the rural mobilizations influenced in the outcome that took the political crisis, which concluded in the implantation of a military government in 1963. This government issued an Agrarian Reform Law in 1964, which modified partially the working relations and the land ownership. And, in addition, it defined a new type of military intervention in the policies that combined repression with reforms. The existence of a landowner social segment that backed a reform in the rural highland (sierra) society has been generally identified by Galo Plaza's figure. In his government (1948-1952), transformations were accentuated in the State intervention, mainly orientated towards the economic and political modernization. This was a new moment of coastal agro-exportation development with the leadership of the banana production. There were stimulated measures of promotion of the production and exportation of bananas. So, the road infrastructure was intensively spread and connected the producing zones with the export ports...

Fluoroquinolone efflux in Streptococcus suis is mediated by SatAB and not by SmrA

Streptococcus suis is an emerging zoonotic pathogen. With the lack of an effective vaccine, antibiotics remain the main tool to fight infections caused by this pathogen. We have previously observed a reserpine-sensitive fluoroquinolone (FQ) efflux phenotype in this species. Here, SatAB and SmrA, two pumps belonging to the ATP binding cassette (ABC) and the major facilitator superfamily (MFS), respectively, have been analyzed in the fluoroquinolone-resistant clinical isolate BB1013. Genes encoding these pumps were overexpressed either constitutively or in the presence of ciprofloxacin in this strain. These genes could not be cloned in plasmids in Escherichia coli despite strong expression repression. Finally, site-directed insertion of smrA and satAB in the amy locus of the Bacillus subtilis chromosome using ligated PCR amplicons allowed for the functional expression and study of both pumps. Results showed that SatAB is a narrow-spectrum fluoroquinolone exporter (norfloxacin and ciprofloxacin), susceptible to reserpine, whereas SmrA was not involved in fluoroquinolone resistance. Chromosomal integration in Bacillus is a novel method for studying efflux pumps from Gram-positive bacteria, which enabled us to demonstrate the possible role of SatAB, and not SmrA, in fluoroquinolone efflux in S. suis.

Aspectos cognitivos en torno a la novela y el cine de la memoria histórica: "La voz dormida" de Dulce Chacón y su adaptación fílmica

Culture, history, and biology are inseparable. Cultural manifestations are necessarily immersed in a context, originate in the embodied minds that create them, and are directed to the embodied minds that receive them and recreate them within their contexts (individual and collective). The novel and the film of historical memory in Spain aim to connect their audiences with a problem that has not been solved, as the Civil War, the postwar, and the pact of forgetfulness left a wide sector of the Spanish society voiceless. During the last few years, a series of initiatives coming from the arts, as well as other realms such as the legal, have sought to reexamine the unhealed wound that still haunts Spanish subjects. La voz dormida [The Sleeping Voice] is one of those initiatives. It begins as testimony, develops into a hybrid and intertextual novel, and later becomes a film. It constitutes an inclusive project, one of offering an alternative version to the “official history”, while incorporating the marginal voices of women that had been left out of the memory of the war and the dictatorship. Objective and Results By examining both the literary and the cinematic versions of Chacón’s work I aimed to evidence the connections that exist between the artistic portrayal of the postwar repression (particularly how it affects women) and the current movement of recovery of historical memory in Spain. Specifically, I was interested in showing how both the novel and the film employ a series of narrative strategies that emphasize the body and intentionality, with the purpose of creating in readers and spectators an empathetic response that may lead to prosocial behavior. In order to carry out this interdisciplinary study, which relates fiction, mind, and socio-historical context, I draw on cognitive theories of literature and film, as well as theories from social and developmental psychology, such as the Richard Gerrig’s theory of narrative experience, Keith Oatley’s psychology of fiction, Suzanne Keen’s theory of narrative empathy, and the empathy-altruism hypothesis, derived form the ideas of Jean Decety, among others...
