      • How Do Early Childhood Teachers Understand and Support the Needs of Young English Language Learners?

        Carolina Cabezas,Elizabeth Rouse 환태평양유아교육연구학회 2014 Asia-Pacific journal of research in early childhoo Vol.8 No.1

        In Australia, over one third of all children in Early Childhood programs speak a first language other than English. Despite considerable work into teachers’ beliefs on cultural diversity, attention to aspects of second language acquisition in the Early Years has been limited within the Early Childhood field. This paper reports on a small study investigating how four early childhood educators understand theory of Second Language Acquisition (SLA) and bilingualism, and how they cater for language-minority students in their programs. The findings revealed a complex interplay between the way participants interpret and support the needs of these children, their experience in the field, and professional education. The teachers in the study reveal various perspectives on how SLA and bilingualism manifest during the early years, and how they affect the learning of children with a Language Background other than English (LBOTE). The teachers also seemed to rely on experiential and intuitive approaches in planning and teaching English Language Learners (ELLs). This study brings new perspectives to understanding the nature of teachers’ beliefs and practice regarding English language learners.

        Characterization of Cellulases of Fungal Endophytes Isolated from Espeletia spp.

        Luisa Cabezas,Carolina Calderon,Luis Miguel Medina,Isabela Bahamon,Martha Cardenas,Adriana Jimena Bernal,Andrés Gonzalez,Silvia Restrepo 한국미생물학회 2012 The journal of microbiology Vol.50 No.6

        Endophytes are microorganisms that asymptomatically invade plant tissues. They can stimulate plant growth and/or provide defense against pathogen attacks through the production of secondary metabolites. Most endophyte species are still unknown, and because they may have several applications, the study of their metabolic capabilities is essential. We characterized 100 endophytes isolated from Espeletia spp., a genus unique to the paramo ecosystem, an extreme environment in the Andean mountain range. We evaluated the cellulolytic potential of these endophytes on the saccharification of the oil palm empty fruit bunch (OPEFB). The total cellulolytic activity was measured for each endophyte on filter paper (FPA). In addition, the specific carboxymethyl cellulase (CMCase), exoglucanase, and β-glucosidase activities were determined. We found four fungi positive for cellulases. Of these fungi, Penicillium glabrum had the highest cellulolytic activity after partial purification, with maximal CMCase, exoglucanase and β-glucosidase enzyme activities of 44.5, 48.3, and 0.45 U/ml, respectively. Our data showed that the bioprospection of fungi and the characterization of their enzymes may facilitate the process of biofuel production.
