Historiographic Metafiction And The Metaphysical Detective In Roberto Bolaño’S Amulet, Rhys William Tyers Jan 2021

Historiographic Metafiction And The Metaphysical Detective In Roberto Bolaño’S Amulet, Rhys William Tyers

Manusya, Journal of Humanities

Roberto Bolaño’s Amulet explores the writing of history as an attempt to construct a narrative from a multitude of unreliable and conflicting sources. As a result, any attempt at historiography is also plagued by the problems of representation found in literature. More particularly, not unlike detective fiction, history is concerned with identifying the inspirations and actions of its players and with revealing the truth about an episode or series of episodes, using historical information, all of which may or may not be reliable. By examining the relationship between the historical and the fictional in Amulet this paper will discuss Bolaño’s …

Multilingualism, Bi/Multilingual Education And Social Inclusion : A Case Study In Southern Thailand, Suwilai Premsrirat, Mirinda Burarungrot

Manusya, Journal of Humanities

In a multicultural-multilingual society, inclusion requires equitable access to quality education as stated – UN Sustainable Development Goals, target 4 (sdg4). In the deep south of Thailand, the majority Muslim population speak Patani Malay in daily life, making language identity an issue as it is not recognized for official use. Students are required to study in Thai and as a result have the lowest academic achievement in the country. Furthermore, parents and the community have no confidence in government schools and some even fear that education is being used to destroy their ethnic identity.
