title: Kaumātua mana motuhake: Kaumātua managing life-transitions through tuakana-teina/peer-education

authors: Hokowhitu, Brendan

abstract: People face signifi cant transition points as they age, such as loss of independent living, loss of a spouse and changing health conditions. Successfully navigating these transitions depends on being able to manage emotional and socio-economic factors, as well as service systems, while often being reliant on family or whānau. Historically however, kaumātua have faced a dominant society that has failed to realise their full potential as they age. Yet, for Māori, kaumātua are “carriers of culture, anchors for families, models for lifestyle, bridges to the future, guardians of heritage and role models for younger generations.” Kaumātua mana motuhake is invested in upholding kaumātua tino rangatiratanga (independence and autonomy) via high-quality Māori research that will lead to better life outcomes for kaumātua and their whā nau.

title: Mai i te kore, ki te pō, ki te ao mārama: He kohinga pūrākau hauora o ngā kaumātua Māori, Māori Elders health and wellbeing stories in life transitions

authors: Shelford, Pita

subjects: pūrākau

abstract: Introduction
New Zealand’s general population is ageing. Kaumātua (Māori elders) only make up approximately 3.1 percent of the total population and yet, they are disproportionately overrepresented in poor health, wellbeing and ageing statistics. However, this is a one-sided story and the focus of a deficit approach. There is a strong need for a strength-based approach where kaumātua voices of problem-solving and resilience related to ageing and the changes it presents, are heard. The purpose of this study is to identify and share those voices and to respond to the call from Māori academics to apply pūrākau as an alternative to Western narrative approaches. Through a pūrākau approach, this thesis sought to answer three key research questions: 

1)What are the cultural and communication features of the kaumātua teina narratives?
2) What are the cultural and communication characteristics of the kaumātua tuakana conversational styles? and 
3) What is the nature of the kaumātua journeys in how the stories unfold, and relationships develop? 

Methods
This study analyses pūrākau from the Kaumātua Mana Motuhake (KMM) collaboration project between the University of Waikato and the Rauawaawa Kaumātua Charitable Trust in Hamilton, Aotearoa New Zealand. The KMM project sought to enhance kaumātua wellbeing during life changes such as losses of licence, independence or spouse, health changes and retirement through a peer-support tuakana-teina programme. The KMM team implemented a tuakana-teina peer support programme where kaumātua (n= 121) engaged in up to three conversations as kaumātua tuakana-teina pairs. The conversations involved exploring the life changes the teina chose with the tuakana guiding the conversations and sharing potential services to help with the changes.
This thesis analysed 30 kaumātua conversations in 10 tuakana-teina pairs to tell a strengths-based story of health and wellbeing. Taking a Kaupapa Māori approach, the research prioritised, privileged and foregrounded Māori and Indigenous epistemology, ontology, and axiology. A pūrākau-grounded analysis approach was developed and applied to the conversations.

Findings
Related to the first research question, the analysis revealed kaumātua narratives that spoke to stories about adversity, turning points, independence and resilience. Regarding the second research question, the study identified key cultural and communicational characteristics kaumātua tuakana used, speaking with words of kinship and reciprocation, words of ignition and guidance, and words of empathy and affirmation. Pertaining to the third research question, the analysis illustrated conversational and relational journey types kaumātua pairs travelled, consisting of conversations that went direct to topics, detours that became defining moments, small tiki tours that came back to the topic, stories that were revisited, and hospitality becoming defining moments. 

Conclusions
The findings compiled weave a collective tapestry of kaumātua teina pūrākau, kaumātua tuakana communication styles, and kaumātua conversational and relational journeys. Kaumātua teina have voiced a pūrākau for us to understand inter-generational trauma and how cultural connection liberated their wellbeing. Kaumātua tuakana have composed a script of communication protocols emphasising connection and relationship development essential to upholding tikanga (practices, principles, communications). The paired kaumātua journeys have drawn a signposted road map that highlighted journey types, emphasising reciprocity in conversing, learning, guiding, connecting, developing, strengthening and enhancing communications, relationships, and wellbeing

Implications
Via kaumātua conversations, invaluable understandings into Māori and Indigenous wellbeing, ageing and development scholarship are offered, strengthening transformation, leadership and resilience theories. Pūrākau and whanaungatanga (relationships) methodologies are advocated for and culturally responsive research is promoted. Health, wellbeing and ageing programme development, policy and service delivery can be practically informed, accentuating mentorship, intergenerational initiatives, and culturally appropriate kaumātua support. Together, the findings can cultivate community wellbeing and nurture cultural continuity.

title: The link between erosion, phosphorus and water quality

authors: Gibbs, Max M.

abstract: In lakes, the solubility of phosphorus (P) in water, and therefore its availability to aquatic plants (macrophytes and algae) for growth, is controlled by oxygen and pH. The supply of dissolved reactive P (DRP) to the lake water column is mostly from sediment release from
decomposing plant material and iron oxides during periods of low oxygen, although in Lake Rotorua and most of the other lakes on the central volcanic plateau, spring-fed streams carry relatively high concentrations of DRP into the lakes. The mechanism for releasing iron-bound DRP from the sediment focusses around the oxidation state iron (Fe) and manganese (Mn). In well oxygenated conditions iron exists in the oxidised state as ferric ions which form ferric oxides that are insoluble in water. These oxides sequester DRP as they precipitate and remove it from the water column. When the oxygen concentration falls to zero (anoxic conditions) iron exists in the reduced state as ferrous ions, which are soluble in water. As the ferric form reduces to the ferrous form it dissolves and the DRP bound to the iron is released into the water column where it is used by algae for growth. The algae eventually senesce and die, returning the P to the sediment as particulate P, where it can be recycled during the next period of anoxia.
Apart from recycling of algal biomass, P also comes from the catchment, bound to the iron oxides in soil particles. The P content of the soil is greatest in the finest soil particles, which are the first to be eroded by rainfall and do not settle until they reach the calm waters of a lake. There they augment the P load from the senescing algal biomass, thereby increasing the amount of DRP that can be released during the next anoxic event. Because of the high background concentration of dissolved inorganic nitrogen in the lake water, the addition of any DRP will stimulate algal growth and thus result in a deterioration of lake water quality. Land management strategies to reduce soil erosion include changes to the way land is farmed and the interception and retention of fine sediment using detention bunds.
