title: Home Care Needs of Older People: Western Bay of Plenty

authors: Glubb-Smith, Kelly

abstract: This qualitative community-led research focused on the formal and informal care needs of older people living in the Western Bay of Plenty, Aotearoa New Zealand. Community groups were concerned about the future health, care, and welfare needs of people aged 65 years and over in this region. The research involves two distinct phases. The first phase involves semi-structured, face-to-face interviews with 26 people aged 65+ years who hope to be able to age at home (owned or rented) and avoid residential or hospital level care as they age. The second research phase involves 13 Needs Assessors and Care Professionals completing an online survey about the needs of older adults living in the community in the Western Bay of Plenty.

title: Measuring electrical properties of batteries at ultra-long timescales

authors: Wilson, Marcus T.

abstract: Quantifying battery behavior is critical to development of new battery technologies and energy storage systems. While it is straightforward to measure properties such as impedance at short timescales (i.e. frequencies larger than ~1 Hz) the relevance of this is questionable since rechargeable batteries in normal usage are often cycled on timescales of hours or days. Making measurements at these timescales, for example impedance measurements below ~1 mHz, is more challenging. In this paper we discuss approaches to quantifying battery behavior at timescales from hours to weeks (frequency scales of ~0.1 mHz down to ~1 μHz). We present frequency domain measurements and time domain measurements, achieved through four-point measurements with a Keysight 66332A at around 100 mA RMS. At low frequencies significant charge is shifted in a measurement cycle, complicating interpretation. The digitization of a sine-wave may introduce errors such as constant current offsets that build in significance with time. The operating point (DC voltage level) of the battery should be controlled since it influences impedance at the lowest frequencies as a result of the voltage-dependent nature of different electrochemical processes. We relate the voltage-dependent effects to time-domain measurements such as cyclic voltammetry and incremental capacity analysis.

title: Māori leaders wellbeing: A self-determination perspective

authors: Roche, Maree A.

subjects: Positive psychology

abstract: This research draws on interviews with 18 Māori leaders from various leadership positions within business, community, political and marae organisations, to garner an understanding of how their leadership roles interact with their own well-being. Analysis of interviews revealed that crosscultural developments in self-determination theory could be gained by incorporating Māori tikanga and values into a model of well-being for Māori leaders. Largely, the principles of tino rangatiratanga (autonomy and self-determination), mana (respect and influence), whānau (extended family), whakapapa (shared history) and whanaungatanga (kin relations, consultation and engagement), were united into a model of leader well-being. This ensured that mātauranga Māori (Māori knowledge) informed our model of Māori leader well-being, while also drawing on the burgeoning Western research in the area of well-being, specifically self-determination theory. Overall, we find that similarities exist with self-determination theory and Māori tikanga and values. However, in contrast to self-determination theory, autonomy and competence are developed within relationships, which means that ‘others’ underpin Māori leaders’ well-being. From this perspective, we present a view of the psychological and well-being resources that Māori leaders draw on to guide them through complex times.
