title: Correlations Between a Cyanobacteria Bloom's Decline and Environmental Dynamics.

subjects: cayanobacteria

abstract: Lake Kainui is an ombrogenous peat lake that is eutrophic and has frequent cyanobacterial blooms.  This research aimed to elucidate the factors that correlated with cyanobacterial bloom decline in Lake Kainui.  Abiotic and biotic variables in Lake Kainui were monitored weekly across the bloom decline phase.  Physicochemical parameters measured included nutrients, micronutrients, water temperature, dissolved oxygen (DO), pH and meteorological variables.  Planktonic and particle-associated bacterial community composition (BCC) was assessed through time using molecular fingerprinting (ARISA).  Total algal, cyanobacterial, planktonic bacteria, planktonic viruses and planktonic crustacean abundances were determined using microscopy.

The bloom decline coincided with multiple factors including; an increasing ratio of TN:TP, changes in the ratio of mixing depth (z¬mix) to euphotic depth (zeu) and pH.  The lake was stratified for several weeks before the decline and the resulting lake stability potentially created an adverse environment for cyanobacterial dominance.  Changes in planktonic biota were various.  Virus dynamics were positively correlated with phytoplankton dynamics.  If virus abundance was negatively correlated to phytoplankton diversity, it would potentially mean that viruses were controlling the phytoplankton assemblage, however virus abundance was positively correlated to phytoplankton diversity, which suggests that viruses had a positive impact on the bloom.  The positive effect was most likely due to to viruses upregulating the amount of dissolved organic matter through lysis.  Bacterial abundance showed no clear correlation with other variables, but bacterial community composition (BCC) shifted as the bloom declined.  Planktonic Cladocera spiked just after the bloom decline.  Bosmina was the dominant species of Cladocera, but was probably too small to ingest colonial Microcystis, which suggests that the Bosmina may be consuming degradation products produced by Microcystis.  These observations indicate that if planktonic biota played a role in bloom dynamics it was most likely due to shifts in the biota causing shifts in trophic cycling that alternately favour or disfavour blooming.

title: Indonesia-PNG Border Security

authors: Norotouw, Pascal

abstract: The field of international relations and security studies is among the most dynamic and challenging aspects of politics. Relationship between states depend on various factors such as politics, economic cooperation and socio-cultural partnerships. Despite the growing interdependency between states through the means of bilateral, multilateral or regionalism, security issues have remained to play a vital role in determining their level of cooperation and coexistence. This qualitative research entitled: Indonesia-PNG Border security, underlines Indonesia and PNG’s foreign policy while addressing the impacts of Papuan separatism on the 750km border. The relationship of Indonesia and PNG has remained cordial and robust over the years, however the existence of the Papuan conflict has often threatened to destabilize mutual understandings between the parties. 
The findings specify that the issue of Papuan separatism is one the sensitive and complicated political and cultural problems of the modern era. The sensitivity that lies behind the Papuan separatism issue has often caused difficulties to Indonesia and PNG policy makers. Border policies are designed to obtain the state objectives; however, cultural aspects have always benefited the third party (OPM) in their existence along the border. Subsequently, the Papuan autonomy has allowed for the acknowledgment of Papuan’s cultural rights. Moreover, the Papuan separatism has managed to gain support from many external parties. The growing participation of external parties have triggered internal security concern. This study indicates that the Papuan separatism issue will remain to influence Indonesia-PNG border security in the years to come. The designing of border policies should focus and encourage more on building trust as means of overcoming misunderstanding. More cooperation between all relative authorities such as the CIQS is vital to maintain a good and favorable a relationship.

title: KAUMĀTUATANGA  Supporting School Leaders To Develop Cultural Values While Resisting The Dominance of Colonialism

authors: Nuri, Ngahuia

subjects: Kaumātua

abstract: In an education system that is asserting to the importance of Māori (indigenous people of Aotearoa) language, culture, identity and the history of Aotearoa  (New Zealand) into the curriculum, there is direction from the Ministry of Education (MOE) for schools to reach out to iwi. What this looks like and how this can be achieved is not an easy task. This thesis follows the journey of three kaumātua (respected, knowledgeable elders, both female and male) working alongside the Senior Leadership Team (SLT) of a decile 10 kura auraki (mainstream primary school) where ākonga Māori (Māori students) were in the minority. The research examines what role kaumātua might have in guiding other schools to help tamariki Māori (Māori children) enjoy and achieve education success as Māori. It highlights the coming together of leaders from two different worldviews with this vision as a common purpose. 

Kaumātua in te ao Māori (the Māori world) are respected elders. Kaumātua are leaders, respected for their wisdom, knowledge and models of behaviour among other attributes. The Māui narratives are one example of demonstrating the characteristics of kaumātua. It was through his respected elders that Maui achieved so much. It was his grandfather who rescued him and taught him all he knew. It was his grandmother Mahuika who gave him fire and it was his kuia (female elder) Murirangiwhenua from whom he received the magic jawbone. The wisdom of Māori kaumātua has been recognised for centuries by Māori and yet kaumātua are often an untapped resource in the mainstream sector of education. In this thesis the kaumātua and members of the SLT share their experiences of working together and the learning and unlearning that has taken place over a period of four years from 2016 through 2019. They share their vulnerability, humility and strength in the goals they have worked towards over this period of time.
