title: Corpus approaches to discourse analysis: Persuasion strategies in a large corpus of #Covid19NZ Tweets

authors: Burnett, Jessie

abstract: Social media platforms afford a window into the fast-paced and ever-changing world of public opinion. The language used in such outlets allows us to interrogate strategies used for constructing different discourse perspectives. In this paper, we investigate links between grammatical constructions (directives) and politeness strategies to express speaker stance in a large corpus of Twitter posts related to Covid19 in New Zealand. The overall aims of the project are to document an under-studied construction (directives) in a sizeable naturally occurring dataset, and to probe the extent to which we see patterns matching linguistic usage with discursive goals.

title: A supercapacitor based enhancement technique for stand-alone surge protection circuits

authors: Fernando, Jayathu

subjects: supercapacitors

abstract: With the International Technology Roadmap for Semiconductors predicting below-25nm feature-size VLSIs, powered by DC power supplies of less than 1V, protection against transients has become mandatory for modern electronic systems. Surge protection circuits are usually designed using non-linear devices such as metal oxide varistors and semiconductor devices and these devices are rated for short-term energy absorption, based on transient waveforms defined by standards such as IEEE C62.41. Despite their very low voltage DC ratings, supercapacitors are characterized by large time constants and significant continuous energy absorption ratings. This paper presents details of a patent-pending technique where multi-winding magnetic core with a supercapacitor based energy absorber stage can be combined with the commonly used non-linear devices, for enhanced protection. Comparison of the supercapacitor-enhanced circuit together with a commercial surge protection circuit is provided.

title: Mining at Te Aroha before the murder in February 1881

authors: Hart, Philip

abstract: Mining was slow to restart after the Christmas holidays on a goldfield whose value was still unknown. Some miners did not return, but other men, mostly with mining experience, replaced them. As was pointed out, more testing was required to justify the cautious optimism, and more explorations did not discover any payable ore or a reef of any sort. More capital was needed to fund adequate development, and the lack of a battery held back the field.
Some searched the nearby countryside, fruitlessly, but at Tui the mostly Maori miners working there seemed to be having better results. Unskilled miners who drove incompetent and even dangerous adits wasted their efforts, while others were accused of shepherding their ground. Two companies formed during January attracted many small investors, but experienced miners started leaving for newer finds, and non-miners abandoned their attempts at mining after discovering that gold was not easy to find. But others remained hopeful, and waited for the erection of a local battery to prove the value of what they had found.
