title: Investigating an open methodology for designing domain-specific language collections

authors: Fitzgerald, Alannah

subjects: corpus-based language learning

abstract: With this research and design paper, we are proposing that Open Educational Resources (OERs) and Open Access (OA) publications give increasing access to high quality online educational and research content for the development of powerful domain-specific language collections that can be further enhanced linguistically with the Flexible Language Acquisition System (FLAX, http://flax.nzdl.org). FLAX uses the Greenstone digital library system, which is a widely used open-source software that enables end users to build collections of documents and metadata directly onto the Web (Witten, Bainbridge, & Nichols, 2010). FLAX offers a powerful suite of interactive text-mining tools, using Natural Language Processing and Artificial Intelligence designs, to enable novice collections builders to link selected language content to large pre-processed linguistic databases. An open methodology trialed at Queen Mary University of London in collaboration with the OER Research Hub at the UK Open University demonstrates how applying open corpus-based designs and technologies can enhance open educational practices among language teachers and subject academics for the preparation and delivery of courses in English for Specific Academic Purposes (ESAP).

title: Integrated Model Development for the Assessment of Food Security in China Related to Climate Change and Adaptation

authors: Wang, Meng

subjects: Climate Change

abstract: This thesis developed a practical methodological framework, which integrated the bio-physical and socio-economic processes within the food system across different scales. The framework provides a useful tool for the assessment of food security and possible adaptation related to climate change. It was applied in China, a country with rapid economic growth and a large population, in order to evaluate multiple dimensions of food security related to climate change and socio-economic development in the future. 

In the framework, an improved bio-physical crop model was coupled with an improved food economic model by scaling up from the farm level to the national level. The bio-physical crop model was developed from the site-based Decision Support System for Agrotechnology Transfer (DSSAT) model in order to investigate the impacts of climate change on physical production of a crop only related to environmental factors. The food economic model was developed from a partial equilibrium economic model, China's Agricultural Policy Simulation Model (CAPSiM). This was done in order to simulate the response of a socio-economic system to the negative consequences on a food economic system from the bio-physical change in crop production due to climate change.

Case studies of China and the Jilin province were investigated by applying the framework. The impacts of climate change on yield and phenology of maize under multiple greenhouse gas emission scenarios were studied at provincial and national levels in three time periods, 2020s, 2050s, 2070s, using the improved bio-physical crop model. In general, maize yield reduction due to climate change ranges from -3% in 2020 to -14% in 2070. The worst yield is -20.5% in 2070 produced under the A1FI scenario. Food security for China until 2050 was projected under multiple climate change and socio-economic scenarios by using the food economic model, and analyzed with respect to food availability, food price and the system resilience to sudden disasters. Modelled climate change impacts on food availability in this study are minimal, producing only a 23 Mt (~8%) gap between supply and demand for maize by 2050. The socio-economic system will compensate for the impacts of climate change on the self-sufficiency of grains by about 8% of total production for the whole country. The impacts on single grain would cause the prices of other grains to rise in future. The effectiveness of potential adaptation measures was assessed quantitatively at both farm and national levels. Uncertainties among different scenarios are discussed for China and the Jilin province.

title: Using the curriculum guidelines for the teaching and learning of te reo Māori in Years 1 – 13 of New Zealand schools to create lessons for young learners

authors: Johnson, Diane

subjects: New Zealand

abstract: In 2009, The New Zealand Ministry of Education published curriculum guidelines for te reo Maori in Years 1 – 13 of English-medium New Zealand schools, that is, from age 5 upwards. These guidelines recommend a communicative approach to the teaching and learning of te reo Māori. In this article, we discuss communicative approaches and provide examples of ways in which teachers can design communicative language lessons that are appropriate for very young learners, lessons that are not only fun but also effective in developing genuine communicative competence in te reo Māori.
