title: Identification and structure elucidation of epoxyjanthitrems from Lolium perenne infected with the endophytic fungus Epichloë festucae var. lolii and determination of the tremorgenic and anti-insect activity of epoxyjanthitrem I.

authors: Finch, Sarah C.

subjects: AR37

abstract: Epoxyjanthitrems I-IV (1-4) and epoxyjanthitriol (5) were isolated from seed of perennial ryegrass (Lolium perenne) infected with the endophytic fungus Epichloë festucae var. lolii. Although structures for epoxyjanthitrems I-IV have previously been proposed in the literature, this is the first report of a full structural elucidation yielding NMR (Nuclear magnetic resonance) assignments for all five epoxyjanthitrem compounds, and additionally, it is the first isolation of epoxyjanthitriol (5). Epoxyjanthitrem I induced tremors in mice and gave a dose dependent reduction in weight gain and feeding for porina (Wiseana cervinata), a common pasture pest in New Zealand. These data suggest that epoxyjanthitrems are involved in the observed effects of the AR37 endophyte on livestock and insect pests.

title: Exogenous events, economic stimulus and its future trajectory

authors: Merrill, Natalie

abstract: The present worldwide COVID-19 pandemic demonstrates that our society is continuously faced with exogenous events. Looking at the past shows policy makers use monetary and fiscal policy to respond to these events; however, the jury is not out for the superior policy or combination of policies to react to exogenous events. The primary research question within this thesis is to determine the most effective and successful economic policy response to exogenous events by using insight from historical natural disasters, terrorist attacks and pandemics. The methodological approach taken within this thesis is a deductivism approach. Specifically, the analysis uses a methodological approach similar to that of an event study methodology. To analyse key macroeconomic variables within a two-year period post the exogenous event studied to analyse how macroeconomic variables responded to the economic response introduced as a result of the exogenous event or lack of, to determine any significant abnormal results. Furthermore, synthetic controls are used to study precautionary savings levels post the exogenous events. Overall, the primary conclusion of this thesis asserted that due to the indirect nature of monetary policy and its diminishing benefits it shall be treated as a defibrillator and not the rehab. Whereas fiscal policy should be the predominant tool used to recover from long-term exogenous shocks, with the key caveat being stimulus is targeted and governments are responsible for taking on debt when the economic benefits stack up.

title: Why do Maori Disconnect?  From their tikanga and legal associated rights and responsibilities within a contemporary world

authors: Jones, Mary Te Kuini

subjects: Ahi Kaa

abstract: This thesis examines some of the reasons why Māori disconnect from their legal and tikanga rights and responsibilities within the contemporary world of today.  The aim of this research project is to identify some of the associated rights and responsibilities of Māori - as land owners, shareholders, Whānau, hapū and tribal members.  Whilst it seeks to reveal some of the desires and visions of the interview participants, the objective is not to seek resolution.  The focus is to identify what deters or dissuades owners from returning and/or participating.  It also seeks to identify whether the assumption or label of disconnection is a reality or myth. 

‘Māori Diaspora’ particularly refers to the substantial increase in outward migration (also referred to as out migration) of Māori leaving New Zealand, and more significantly migrating to Australia, which was in direct response to the neo-liberal reforms of the late 1980’s (Smith L. , 2006).   With the New Zealand government refusing to acknowledge the negative impact their legislation and policy had on Māori, they continued to introduce new systems that were ultimately designed to push many to breaking point.  
Māori who could no longer bear the cumulative effects of such oppression emigrated in search of better economic opportunities and a higher standard of living for their families.  Meanwhile, back home in Aotearoa, the Māori Diaspora left behind a complex set of problems in its wake with diminishing hapū and tribal members driven from their homeland who are gradually becoming dis-connected and estranged from their whenua tipu.   

Whilst repatriation is an uncomfortable topic for many Māori who wish to retain their overseas residency, many continue to dismiss the compounding effects of their absence and the heavy burden carried by those who remain in Aotearoa to keep the home fires burning (or the ‘ahi kaa’).
