title: IntCal13 and Marine13 radiocarbon age calibration curves 0-50,000 years cal BP

authors: Reimer, Paula J.

abstract: The IntCal09 and Marine09 radiocarbon calibration curves have been revised utilizing newly available and updated data sets from 14C measurements on tree rings, plant macrofossils, speleothems, corals, and foraminifera. The calibration curves were derived from the data using the random walk model (RWM) used to generate IntCal09 and Marine09, which has been revised to account for additional uncertainties and error structures. The new curves were ratified at the 21st International Radiocarbon conference in July 2012 and are available as Supplemental Material at www.radiocarbon.org. The database can be accessed at http://intcal.qub.ac.uk/intcal13/.

title: Curriculum enactment, challenges and enablers for change and transformation in early childhood education

authors: Ong, Patricia Ai Lay

subjects: Curriculum enactment

abstract: This research study examines the ECE curriculum in the changing and evolving landscape of early childhood care and education in a diverse and globalized society and world that is becoming increasingly connected via advances in communicative technology. The study aimed to explore the relationship between the enacted curriculum and the intended curriculum as guided by the national curriculum framework in diverse early childhood education settings in Singapore. With broad objectives framing the study, an exploratory sequential QUAL-quan mixed methods research design was adopted. The first phase involved visual ethnography and netnography, as well as interviews with twenty-two teacher participants. In-depth interviews with five of these twenty-two participants provided a greater depth of understanding of the perspectives and experiences of the early childhood educators. These interview findings, together with participant-generated data were collated in the qualitative phase. A survey instrument was designed drawing on the data derived from the first phase of the study, as well as relevant research literature. Mixed methods research was considered as it is able to integrate qualitative and quantitative data collection techniques; giving voice to participants and allows a greater comprehensiveness by addressing the research questions through complementary approaches. The qualitative phase enabled a more detailed investigation on curriculum enactment and the challenges faced by teachers in ECE settings while the quantitative allowed a more objective description of various aspects of curriculum delivery and challenges faced. The study also identifies some of the enabling conditions that have allowed transformation and positive change within the context of early childhood services in Singapore. The thesis also argues for the development of a sustainable and future oriented approach to the curriculum through the blending of approaches that include the adoption of not only the national curriculum guidelines, but also more international modern approaches that challenge localized practices and traditions. It also contends that a pedagogical third space in the curriculum allows for a more inclusive approach that is both culturally and practically relevant. The implications of this study are tied to teacher preparation, professional development, in-service learning and future-oriented curriculum development and research directions.

title: The TOHU framework: Sensing and interpreting tohu to heal from trauma

authors: McLachlan, A

subjects: Environment

abstract: This hypotheses article presents understandings and practices of tohu (signs) in the personal, eco-environmental, and spiritual wellbeing of Māori. Tohu can be observed in the natural, social, physical, or spiritual environment, and within a Māori worldview provide important ways of understanding and responding to phenomena. Wānanga (shared dialogue and debate) were held with seven Māori clinical psychologists from He Paiaka Tōtara (Māori Psychologist Network) and two mātauranga Māori specialists to explore their experiences, knowledge, and perspectives about tohu, with their insights collected through online information sharing. Our wānanga goals were to inform the creation of a therapeutic framework to address patu ngākau, psychological and spiritual trauma experienced by Māori. The results identified that tohu are located within the person and their environment, and the importance of exploring how tohu are interpreted. We propose a TOHU acronym as a framework for understanding and addressing the multifaceted impacts of patu ngākau.
