title: Optimal energy supply structures for industrial sites in different countries considering energy transitions: A cheese factory case study

authors: Philipp, Matthias

abstract: This present study focuses on analysing the most efficient utility energy supply structure in terms of primary energy efficiency, carbon emissions and energy costs. In the German dairy industry, separate conversion with gas fired steam boiler, and cooling with ammonia chillers are the-state-of-the-art technologies. It is attractive due to its robustness and low investment costs. But given the ongoing energy transition to renewable energy, opportunities to reduce emissions will become increasingly important. There are other energy supply options, such as Combined Heat and Power (CHP) and Heat Pumps (HP), that if implemented need to compete against the conventional energy supply systems. One option is CHP to provide cogenerated electricity and heat while cooling remains supplied by ammonia chillers. In countries with high electricity Grid Emissions Factors (GEF) such as Germany and the USA, the use of decentralised CHP results in savings of primary energy and emissions. However, this option is less attractive for countries with low GEF such as France and Norway, and for places like Germany where the energy transition lowering its GEF by 50 % in 2030. In these cases, HP solutions provide the lowest emissions and highest primary energy efficiency.

title: Iranian EAP practitioners’ competences, practices, and professional development

authors: Kaivanpanah, Shiva

abstract: Given the importance of teaching methodology in English for Academic Purposes (EAP) and professional development (PD) for EAP teachers, this survey examined and explored the differences of the self-adjudged perceptions of EAP practice competences and PD activities of two main groups of Iranian teachers: those with an English language teaching (ELT) background and subject content teachers who teach EAP. A sample of 105 EAP teachers (53 English language teachers and 52 content teachers) responded to two questionnaires: a granulated, 72-item questionnaire exploring competences in a wide variety of aspects of EAP practice and a smaller 19-item questionnaire relating to frequency of participation in PD activities. Additionally, the teacher data sets were triangulated by the use of a 58-item questionnaire completed by 502 Iranian undergraduate students taking EAP courses. The teacher questionnaire findings indicated higher self-adjudged competences by the ELTbackground teachers in the areas of receptive and productive skills, grammar and vocabulary, feedback and error correction, and assessment and evaluation. Similarly, the student questionnaires rated those teachers with an ELT background more highly in the same five areas. The implications of the findings for the future development of EAP in Iran in terms of teacher development and further research are then discussed.

title: Te aho tapu: Mātauranga a Māui ancient knowledge and preserving culture through practice

authors: Keelan-Peebles, Jacqueline Roberta

abstract: I am Māui I am not Māori. Reclamation of identity as uri o Māui-tikitiki-a-Taranga is the ngako of  this creative thesis, in response to the question, ‘who were we before and what is Māuitanga’? 
Due to its paucity my intention is to revive its frequency in restoration to its rightful status in this way; the tools to navigate authentication is through the lens of mātauranga Māui, embedded in kōrero tawhito, traditional cultural practice, lived experience and whakapapa. Validation is  founded in our iwi repositories, pūrākau, ngā waiata, mōteatea, karakia, whaikōrero, rituals of encounter and the arts.
Raranga as the creative vehicle affords the means to analogize kaupapa Māui. The creation of a Kākahu/Korowai is the appropriate representation as its significance aligns itself with the mantle of honour due to rangatira living and those who have passed. 
Exploration of kaupapa Māui infrastructure is fundamental to unravelling multi-faceted cultural narratives. These are the mechanisms to the reclamation of who we were before and to answer the question of Māuitanga. Ultimately to claim and to restore my heritage, to reinstate the common use of an ancient iwi, te iwi ‛Māui’.
