Origen de la identidad peruana en el mito de Huarochiri
Get PDFEl mito de HuarochirĂ está representado en la sierra central del PerĂş, en la provincia de HuarochirĂ, la cual pertenece al departamento de Lima. Este mito, puesto que la cultura quechua no tuvo escritura, fue recopilado de la tradiciĂłn oral, despuĂ©s de la influencia y afirmaciĂłn de la religiĂłn cristiana sobre las creencias religiosas incas. El fundamento esencial del mito radica en el aspecto religioso que se quiere perpetuar; sobre todo representa la lucha constante que hay, en el ambiente religioso, entre el bien y el mal
Transparent support for partial rollback in software transactional memories
Get PDFThe Software Transactional Memory (STM) paradigm has gained momentum thanks to its ability to provide synchronization transparency in concurrent applications. With this paradigm, accesses to data structures that are shared among multiple threads are carried out within transactions, which are properly handled by the STM layer with no intervention by the application code. In this article we propose an enhancement of typical STM architectures which allows supporting partial rollback of active transactions, as opposed to the typical case where a rollback of a transaction entails squashing all the already-performed work. Our partial rollback scheme is still transparent to the application programmer and has been implemented for x86-64 architectures and for the ELF format, thus being largely usable on POSIX-compliant systems hosted on top of off-the-shelf architectures. We integrated it within the TinySTM open-source library and we present experimental results for the STAMP STM benchmark run on top of a 32-core HP ProLiant server. © 2013 Springer-Verlag
Intercultural activities in English language teaching: a contribution to understand English as a lingua franca (ELF)
Get PDFCurrently, English has acquired the status of Lingua Franca enabling world communication (CRYSTAL, 2003; SEIDLHOLFER, 2011). However, in the context of English language teaching (ELT), it is necessary to develop the idea of what the concept of ELF may contribute to students’ awareness and development. This is even more relevant when we talk about pre service teachers who are in the process of learning important abilities for teaching English in a globalized context (SEIDLHOFER, 2011; SIQUEIRA, 2008; CRYSTAL, 2003; ORTIZ, 2003). One of English as a Lingua Franca’s (ELF) characteristics is that it considers the nature of interculturality allowed by language (SIQUEIRA, 2008). The objective of this paper is to observe how students may understand the concept of ELF through the development of activities that promote intercultural discussions in an EFL tertiary context in Alagoinhas, Bahia, Brazil. The main question to investigate is in what ways a proposal of activities which consider intercultural aspects can contribute to understand the concept of ELF and therefore help in the education of English’s future teachers in the country. In order to develop the research, some activities which consider intercultural aspects of texts are proposed to the teachers-to-be who will take part in the research, and some observations and discussions are performed before, during and after the classes. The analysis is developed by considering an intercultural dialogue based on the view of: a) language and culture as places of interaction (KRAMSCH, 1998; MENDES, 2008); b) focus on the language meanings produced and on the access to new possibilities of representation (KRAMSCH, 1993); c) selection and production of materials with authentic contents and cultural meanings (MENDES, 2008) which is possible through the understanding of ELF (SEIDLHOFER, 2011)
