Science Letters:A modified chlorophyll absorption continuum index for chlorophyll estimation

INTRODUCTION Great advance has been achieved in vegetation characterization with remote sensing techniques. Most spectral vegetation indices (VIs) are usually calculated as the combinations of red and near-in- frared (NIR) reflectance because the information contained in a single spectral band is insufficient for characterizing vegetation status as vegetation exhibits unique reflectance properties in these bands. These VIs can be generally grouped into ratio indices and orthogonal indic…

‘Korea … it's not really actually an Asian country’: Australian children's experiences of an intercultural school partnership programme

ABSTRACT

In Australia, intercultural understanding has been prioritised in education and curriculum documents at both federal and state levels. Alongside this educational priority, schools have also been encouraged to demonstrate ‘engagement’ with ‘Asia’, such as through a partnership with another school in the Asia-Pacific region. My research findings are based on an ethnographic study of Year 5 and 6 Australian children's experiences of an intercultural school partnership initiative through on-line classroom exchanges over a two-year period. Through a critical analysis of ‘complexity reduction’ I draw attention to the processes through which children made sense of perceived racial and cultural differences as part of their involvement in partnership activities and conclude with some reflections on the extent to which educational initiatives such as intercultural school partnership programmes that aim to foster intercultural understanding can do so without reinforcing unequal intercultural relations and stereotypes.

Sensitivity analyses of cables to suspen-dome structural system

The construction of the cables is a key step for erecting suspen-dome structures. In practical engineering, it is difficult to ensure that the designed pre-stresses of cables have been exactly introduced into the structures in the site; so it is necessary to evaluate the influence of the variation of the pre-stresses on the structural behavior. In the present work, an orthogonal design method was employed to investigate the pre-stressed cables'sensitivity to the suspen-dome system. The investigation was concentrated on a Kiewitt suspen-dome. Parametric studies were carried out to study the sensitivity of the structure's static behavior, dynamic behavior, and buckling loads when the pre-stresses in the cables varied. The investigation indicated that suspen-dome structures are sensitive to the pre-stresses in all cables; and that the sensitivity depended on the location of the cables and the kind of structural behavior. Useful suggestions are given at the end of the paper.     

Researching and developing interdisciplinary teaching: towards a conceptual framework for classroom communication

Calls for teaching and learning that cross subject boundaries have been making themselves heard in recent Higher Education literature in different national contexts. Communication is pivotal in any such learning encounter: it is in the process of negotiating meaning across disciplines that its rewards and challenges lie. And yet, the question of what characterises interdisciplinary classroom communication in the sector is little researched and little understood. How such interaction differs from that in the monodisciplinary university classroom is under-theorised. Adapting Applied Linguistic theory in Intercultural Communicative Competence (Byram, M. (1997). Teaching and assessing intercultural communicative competence. Clevedon: Multilingual Matters.) and drawing on a taxonomy of academic disciplines (Becher, T., & Trowler, P. R (2001). Academic tribes and territories.Buckingham: Society for Research in Higher Education/Open University Press.), the article proposes a model of Communicative Competence as a conceptual tool to shape thinking in developing and researching interdisciplinary teaching and learning in the university classroom.

Urban youths’ hybrid positioning in science practices at the margin: a look inside a school–museum–scientist partnership project and an after-school science program

In what ways do urban youths’ hybridity constitute positioning and engagement in science-as-practice? In what ways are they “hybridizing” and hence surviving in a system that positions them as certain types of learners and within which they come to position themselves often as other than envisioned? To answer these questions, I draw from two ethnographic case studies, one a scientist–museum–school partnership initiative, and the other, an after-school science program for girls only, both serving poor, ethnically and linguistically diverse youth in Montreal, Canada. Through a study of the micro dialectics from the perspective of youth, I show what we can learn from examples of doing science in a formal and informal educational context supportive of marginalized science practices resembling in part, at least, science-as-practice. Through an integration of the findings with current discourses of relevance in science education such as funds of knowledge and youth centered, co-opted science, I contribute to the formulation of a global pedagogy of science education and in particular, what such may imply in the eyes of youth in French Canada.     

International students in the first years of senior secondary schooling in Australia: Longing for belonging

Most research on international students’ experiences has focused on tertiary settings and consistently shows that this cohort negotiates significant risks during their time abroad. This paper draws on data from the first year of a three-year Australian Research Council funded study to address the un(der)examined cohort of young people who complete their secondary school education as international students and temporary sojourners in Australia. We analyse the data from the initial interviews undertaken with 60 Year 10 international students during their first year of the senior secondary schooling. Drawing upon the theoretical resources associated with the politics of belonging, we ask if, and in what ways, students felt themselves to be marked as ‘other’ to constructed educational and social norms. We note the significant role that online activity played in helping students deal with feelings of disconnect and exclusion.
