Dinámica de un sistema producción-inventario con restricción de capacidad

Los sistemas de producción-inventario son estudiados a través de modelos lineales y no lineales, determinándose sus propiedades mediante códigos numéricos. El aporte de este trabajo es la aplicación de la teoría de sistemas dinámicos al análisis de un modelo no lineal de un sistema de este tipo. Este enfoque nos permitió caracterizar en forma rigurosa su dinámica, sin la necesidad de recurrir a métodos numéricos. Demostramos que la política de decisión propuesta conduce a soluciones no oscilatorias y por lo tanto no es posible el régimen caóticoSociedad Argentina de Informática e Investigación Operativ

Transcultural body spaces: re-inventing and performing headwrap practice among young Congolese women in London

This article examines embodied representation of race, ethnicity, and gender, questioning ideas of cultural appropriation. Using the London-based Congolese transnational fashion brand Kiyana Wraps as a case study, the article addresses how young Congolese designers re-invent their cultural heritage to conceive the label stylisation and construct meanings of Blackness/Africanness. The article also explores the brand’s social spaces, where the headwrap ritual is used by different actors to perform hybrid identities. In addition, wearing the headwrap reveals symbolic metaphors of empowerment, through which intertwined ‘feminist’ and ‘feminine’ identities are evoked. The paper examines how Congolese women are creatively taking inspiration from the environment of London to produce innovative fashion trajectories as lived socio-cultural experiences. It argues how the headwrap ritual signifies an aesthetic and material process through which specific racial and ethnic boundaries are transcended, fabricating transcultural body spaces which encompass individuals with diverse cultural backgrounds

Changing perspectives of literacy, identity and motivation: implication for language education

This chapter affirms the value of secure but flexible cultural identities in developing a form of critical intercultural literacy which is not merely as a set of skills, but a deeper set of understandings. Drawing on the findings of a study of a migrant group in Australia, it suggests that such literacy can be acquired in third spaces between the familiar and the new. From a sociocultural perspective, it is argued that for successful language learning and social interaction, the development of critical intercultural literacy should overarch the narrower concepts of communicative competence and cultural literacy. It is also argued that teaching and learning are much less effective if educator and learner cultural values conflict, and if school literacy learning does not connect with personal experience
