title: Biological activated carbon and advanced oxidation processes for the removal of cyanobacterial metabolites in drinking water treatment

authors: Bernstein, Daniel Richard

subjects: water treatment

abstract: Biological activated carbon (BAC) and advanced oxidation processes (AOPs) are often used in conjunction during drinking water treatment for the removal of trace organic compounds that are not effectively removed during traditional treatment processes such as coagulation, flocculation and sand filtration. These trace organic compounds include toxic cyanobacterial metabolites such as saxitoxins and taste and odour (T&O) causing compounds like geosmin and 2-methylisoborneol (2-MIB) which are produced by a number of bacterial species including cyanobacteria. At present, the Hamilton Drinking Water Treatment Plant (HDWTP) employs the use of BAC as part of the final stage of drinking water treatment for its municipal water supply. This article provides a general overview of the chemical and physical processes involved and a review of the current state of AOP technology.

title: University governance: Governing bodies as providers and users of annual reports

authors: Dixon, Keith

subjects: accountability

abstract: Where members of governing bodies of universities stand in relation to their institution’s annual reports is discussed in the broader context of trends in university governance. Data were collected from members of the governing councils of New Zealand’s eight universities using questionnaire surveys in 1993 and 2001. During this interval, a marked improvement in the quality of these institutions’ reports occurred (Coy, D. and Dixon, K. (2004). British Accounting Review 3, 679–106). Issues explored include information used to govern and the equivocal roles of council members juxtaposed as they are between university participants and stakeholders. They are cast as strategic decision makers, holders of university senior management and other participants to account, and annual report publishers, and so publicly accountable persons. Findings include that annual reports provide valuable information for members to make decisions and hold their universities accountable; and that some shortcomings discerned by members in report qualitative characteristics and contents persist, despite seeming to be within the discretion of councils to address. Speculations about why this might be so are advanced, including for further investigation; and other suggestions for further research are put forward.

title: Incidental teacher<->student moments in an Aotearoa New Zealand secondary school: Entangled encounters with key competencies

authors: Graham, Judith Ann

subjects: key competencies

abstract: This study focuses on the performance of Key Competencies of the New Zealand curriculum in incidental teacher<->student moments. It makes visible a significant and often taken-for-granted portion of teachers’ daily work. Situated in one Aotearoa New Zealand secondary school, the research material of this study was generated in two cycles of conversations with teachers. In these conversations the teachers spoke about ordinary, unplanned moments with students. As the school is composed of more than 50% Māori students, I spoke first with individual Māori teachers at the school, inquiring into their knowledge of key competencies, and how that pedagogical knowledge related to knowledge and practice from whakaaro Māori. In the second cycle of generating research material, a collaborative group of Māori and Pākehā teachers engaged in a recursive process of inquiring together into stories participants told of everyday encounters with students. In this inquiry the names of key competency categories were put in the background as the group focused their inquiry on the teacher’s values, knowledges and beliefs that were contributing to action in the moment.
My analysis of the research material is situated in the field of posthuman philosophy and relational<->materialist theorising. Drawing on the work of Deleuze and Guattari, Massumi, Barad and Bennett, I applied Barad’s methodology of diffractive analysis and paid attention to multiple material and discursive forces and intensities at play in each story. In this analysis, diverse forces such as colonised histories, educational discourse, human and more-than-human materialities, whakaaro Māori, hope and belief, were evidenced intra-acting together. I noticed how these forces invited the mobilisation and performance of key competency actions in the service of becoming and relating with the world.
This study shifts thinking with key competencies from the reductionist territory of the individual human and re-territorialises them as dynamic performances of becoming. It contributes to a re-thinking of subjectivity and potentiality in the place of schooling in Aotearoa New Zealand. As the multi-dimensional entangled complexity of day-to-day pedagogical encounters is disclosed, teacher<->student intra-actions become known as ripe opportunities for performances of actions that come under the umbrella of key competencies. The study opens new ways of thinking about how key competency learning is produced in secondary schools, and how the placetimemattering of the school shapes that learning.
I explore diffractive patterns as key competencies entangle with posthumanism and with whakaaro Māori in everyday teacher<->student encounters. I present a way of thinking with key competencies that aligns closely with whakaaro Māori and posthumanism, and offers a creative and ethical orientation to life and learning. I think with the teacher<->student relational moment as a significant site of learning, and how knowledge of affect and relational-practices of knowing and recognition might contribute to teachers’ professional adaptive expertise.
