title: Perceptions of coarse anglers and freshwater managers, and the impact of these perceptions on management of non-indigenous invasive fish

authors: Duggan, Kathryn S.

abstract: This report examines coarse angler attitudes and behaviours to determine the reasons for, and develop incentives to successfully discourage, deliberate spreads of coarse fish species. The perceptions of freshwater managers, and the ways in which these human perceptions influence management of non-indigenous invasive fish, are also explored. To achieve this two main methodological strategies were employed: (1) semi-structured interviews with representatives from management agencies, research providers, iwi, the New Zealand Federation of Coarse Anglers, and individual coarse anglers: and (2) an internet survey with individual coarse anglers. In contrast to many New Zealanders, coarse fish species are highly valued by coarse anglers and the practice of coarse fishing is an important part of their lives. While a large portion of coarse anglers state they would like more fishing opportunities (especially outside of the Auckland/Waikato region), they argue that they do not practice or support illegal spread of coarse fish.

title: The relationship between Māori cultural identity loss & rangatahi Māori suicide

authors: Graham, Shaquille

subjects: Māori

abstract: This research explores the relationship between Māori cultural identity loss and rangatahi Māori suicide in Aotearoa. The McLachlan et al. (in press) Whiti Te Rā model of cultural identity was employed to frame the investigation with specific analysis into the six critical cultural ara of Whakapapa, Reo Māori, Taiao, Mahi-a-toi, Take pū whānau and Wairuatanga. A Kaupapa Māori research approach was utilised for cultural applicability and the promotion of Tino Rangatiratanga. Qualitative methodology guided data collection and analysis. Data collection involved (i) literature reviews and (ii) interviews with whānau members of rangatahi lost to suicide, seeking to understand the āhuatanga of the six cultural ara within the case studies (n=5). Interviews were governed by a semi-structured technique that looked to understand (i) the factors influencing the strength or weakness of each cultural ara; (ii) the state of health within each cultural ara; (iii) and identify causal relationships between cultural ara and wellbeing outcome. Reflexive thematic analysis showed that geographical location, generational knowledge transmission, and individual and whānau engagement were the global themes influencing either the diminishing or strengthening of cultural identity. Ngā Ara Wairua and Take pū whānau were also portrayed as the most compromised. The research suggests that optimal access to the three global themes potentiates rangatahi Māori to cultural flourishing and Mauri Ora; proposed as the most significant deterrent for suicidality. Contrastingly, suboptimal access to the three global themes is proposed as diminishing cultural ara as expressed in a state of Mauri Moe, where rangatahi Māori wellbeing is most vulnerable, and where suicidality has the greatest potentiation.

title: Exact models for hall current reconnection with axial guide fields

authors: Craig, Ian J.D.

subjects: mathematics

abstract: This paper employs an analytic reconnection model to investigate the conditions under which Hall currents can influence reconnection and Ohmic dissipation rates. It is first noted that time dependent magnetohydrodynamic systems can be analyzed by decomposing the magnetic and velocity fields into guide field and reconnecting field components. A formally exact solution shows that Hall currents can speed up or slow down the reconnection rate depending on the strength and orientation of the axial guide field. In particular, merging solutions are developed in which the axial guide field is the dominant driver of the reconnection. The extent to which Hall currents can alleviate the buildup of back pressures in flux pile-up reconnection models is also examined. The analysis shows that, although enhancements of the merging rate can be expected under certain conditions, it is unlikely that Hall currents can completely undo the fundamental pressure limitations associated with flux pile-up reconnection.
