title: Reply to Mahowald and Gibson and to Heggarty: No problems with short words, and no evidence provided

authors: Pagel, Mark

abstract: Mahowald and Gibson (1) suggest that the shorter word length of frequently used words, and not their stability, could mean that chance sound correspondences account for the pattern of results we report for cognate relationships among proto-words in our study of seven Eurasian language families (2). However, their −0.24 correlation between the phonological length of contemporary English words and our measure of cognate class size is not relevant to the question of chance sound correspondences among the proto-words from different language families. What must be demonstrated is that shorter proto-words were more likely to be judged cognate simply on the basis of their length.

title: Supercapacitor assisted LDO (SCALDO) techniquean extra low frequency design approach to high efficiency DC-DC converters and how it compares with the classical switched capacitor converters

authors: Kankanamge, Kosala

abstract: Supercapacitor assisted low dropout regulators (SCALDO) were proposed as an alternative design approach to DC-DC converters, where the supercapacitor circulation frequency (switching frequency) is in the order of few Hz to few 10s of Hz, with an output stage based on a low dropout regulator stage. For converters such as 12–5V, 5–3.3V and 5–1.5V, the technique provides efficiency improvement factors of 2, 1.33 and 3 respectively, in compared to linear converters with same input-output combinations. In a 5–1.5V SCALDO regulator, using thin profile supercapacitors in the range of fractional farads to few farads, this translates to an approximate end to end efficiency of near 90%. However, there were concerns that this patented technique is merely a variation of well-known switched capacitor (charge pump) converters. This paper is aimed at providing a broad overview of the capability of SCALDO technique with generalized theory, indicating its capabilities and limitations, and comparing the practical performance with a typical switched capacitor converter of similar current capability.

title: Mental health inpatient services: Improving our understanding of the needs of Maori when acutely unwell

authors: Wharewera-Mika, Julie

subjects: Maori

abstract: There are many possible explanations for the pattern of Maori overrepresentation in mental health acute services. This research project focuses on how services can optimally meet the needs of Maori to improve outcomes. This doctoral research in progress is about claiming space for Maori to have a voice in identifying factors that contribute to recovery and Whanau Ora, and offering recommendations to improve the effectiveness of existing services to better meet the needs of Maori Tangata Whaiora and Whanau.
