title: Dialogic ruptures: An ethical imperative

authors: Arndt, Sonja Kathrina

abstract: Dialogue is promoted as a key strategy to ‘solve’ the ‘problem’ of diversity in educational set- tings. Yet, “[w]hen we select words ... We usually take them from other utterances, and mainly from utterances that are kindred to ours in genre, that is in theme, composition or style” (p. 87, emphasis in the original). This article problematises the complexities of dialogic engagements with foreigner teachers in educational encounters. Bakhtin’s treatment of poly- phonic dialogic encounters provides an analytical frame for explicating the intertextuality of foreigner teacher engagements as not only temporally and culturally, but also individually volatile. The article suggests that dialogic encounters are unpredictably complex, alive and never neutral, and that dialogic engagements can be so fraught with fear that verbal or cross cultural engagements with teacher foreigners must be recognised as risky and dangerous, and not always smooth ‘solutions’ to a ‘problem’. A dual Bakhtinian/Kristevan lens expands the analysis to expose the vulnerability of dialogue, through unconscious revelations of teacher subjects that are forever in process. The article culminates in an argument for the crucial importance of a receptive, attentive ethics of care in dialogic engagements with cultural for- eigners in educational relationships, to avoid fearful exposure, lifeless dialogue and silence.

title: Do Golden Parachutes increase CEO’s DESIRE to be taken over? empirical evidence from australia and united states

authors: Reddy, Krishna

subjects: change in control payments

abstract: This study investigates whether the large payouts that are available to Chief Executive Officers (CEOs) from a change in corporate control (takeover) do motivate some CEOs to seek acquisition of their firms by making them more attractive to a takeover bid. Using Australian and the US data, employing OLS regression, we report that there is a significant relationship between a CEOs change in control payments and their firm’s net cash levels (one of the key factors of takeover attractiveness). Our empirical results also indicate that CEOs desire their firms to be acquired by decreasing shareholders’ equity, thus supporting the view that change in control payments exist primarily for incumbent managers. Our findings provide support to the proposition that managers enjoy having large cash balances to be available to them as it allows them with greater opportunities to derive personal benefit from it. Therefore, our findings suggest that managers prefer to have large cash balances available to them to ensure their future wellbeing by setting up favourable terms in the control agreements.

title: The use of functionalised biochar to enhance phosphorus removal in woodchip bioreactors. The integration of mātauranga Māori to enhance the cultural aspects of woodchip bioreactors.

authors: Taoho, Brandon

subjects: Woodchip bioreactor

abstract: Nutrient pollution, resulting from excessive releases of nitrogen (N) and phosphorus (P) into waterways, poses a significant threat to aquatic ecosystems worldwide. Elevated nutrient levels can result in eutrophication, which can have detrimental effects on the health of waterbodies and their biota. Woodchip bioreactors are effective, edge-of-field technologies that can help mitigate nutrient pollution by lowering nutrient concentrations in agricultural drainage systems known to carry leached N and P into waterways. However, one limitation to their design is their ineffectiveness at removing P. The inclusion of functionalised biochar is one potential solution to enhance P removal in woodchip bioreactors. There is a growing need to mitigate nutrient pollution in New Zealand that does not depend on a western-centric perspective only. Integration of mātauranga Māori and western science into the design and operations of a woodchip bioreactor is one approach to incorporate both knowledge systems to the goal of mitigating nutrient pollution. In this dissertation, a column experiment was used to compare the P removal efficiencies of two treatments of functionalised biochar, and one treatment of woodchips when subjected to stream water spiked with P. Subsequently, a single phosphate extraction was done to determine the phosphate absorption capacities of each treatment. The results showed that the two functionalised biochar treatments had the highest efficacy in reducing P concentrations in the P-spiked stream water compared to the woodchip-only treatment. Both treatments also showed higher P absorption, evidenced from the Fe-P/Feox ratio, within the phosphate extraction experiment. A wānanga was organised at Matahuru Marae, Lake Waikare, to share mātauranga Māori on how to culturally enhance woodchip bioreactors from a Te Ao Māori perspective. Participants recommended that native woodchips be incorporated into woodchip bioreactors because of their inherent association to the land and people. Overall, the results implied that functionalised biochar is an effective solution to enhance P removal in woodchip bioreactors due to their biophysical properties to absorb and retain P. Secondly, incorporating native woodchips into woodchip bioreactors systems potentially offers a sustainable and culturally respected alternative to conventional wood chips, aligning with Māori values and tikanga
