title: Multiple small monthly doses of dicyandiamide (DCD) did not reduce denitrification in Waikato dairy pasture

authors: Watkins, Natalie Lisa

subjects: denitrification

abstract: The effectiveness of multiple small doses of the nitrification inhibitor dicyandiamide (DCD) to decrease denitrification under warm moist conditions was tested in a 1-year field trial on a grazed dairy pasture. DCD was applied approximately every 4 weeks as an aqueous spray onto ten replicate plots 3 days after rotational grazing by dairy cows. Each application was at the rate of 3 kg DCD ha⁻¹, with a total annual application of 33 kg ha⁻¹. Denitrification was assessed 5 days after each DCD application using the acetylene block method. At the end of the trial, the rate of degradation of DCD under summer conditions was measured. DCD significantly decreased the mean annual nitrate concentration by about 17%. Denitrification and denitrification enzyme activity were highly variable and no significant effect of DCD in decreasing denitrification was detected. In the summer month of December, DCD degraded rapidly with an estimated half-life of 5 ± 3 days (mean and standard deviation).

title: Engaging Corrupt Somalia

authors: Leslie, Mathew

subjects: Corruption

abstract: This thesis addresses a fundamental question, which is particularly relevant in the Somali context; why has corruption remained endemic in international aid programmes in Somalia? In researching and analysing this question this thesis examined the characteristics of the aid systems in Somalia, which provide an enabling environment for corruption against the application of a consociationalist democratic model. Indicators of success for international interventions in Somalia surround expenditure, presence, influence, geo-political interest and security, and have not included the promotion of Somali-centric models for good governance, transparency and accountability – key actions necessary to help mitigate corrupt practices. Consequently, this thesis examines corruption in Somalia, and its presence in international aid based upon three key factors - adverse clan self-interest, international geo-political self-interest, and lack of effective state building support. While consociationalist theory provides an opportunity for Somalia to address such gaps, this will require a comprehensive and holistic approach and a commitment by the clans in Somalia to collaborate rather than continue to engage in corrupt, self-interested and opportunistic behaviours.

title: Te Puea Herangi: an ethno-biographical study

authors: King, Michael

abstract: Early explanations of Maori leadership (for example Buck 1950) tended to emphasize the principle of male primogeniture - the expectation that community leadership would in the normal course of affairs pass to the eldest sons of lines of first-born males. Later studies of Western-educated leaders and those with a non-traditional power base (see Butterworth 1969, Cody 1953, Condliffe 1971, and Henderson 1972) continued to emphasize male primacy. Against the tenor of these studies, however, is the fact that in the first half of the twentieth century the Maori King Movement was dominated and welded together by a woman who preached male primogeniture though her life seemed to contradict the principle; Te Puea Herangi was not of a senior descent line and neither compensated for its absence by a substantial degree of European education nor consolidated her position by marriage. Nor was she simply a forceful leader in Maori terms only: Professor J.G.A. Pocock (in The Maori and New Zealand Politics) called her “possibly the most influential woman in our political history”.

This study examines Te Puea's leadership role: how she came to assume it, how she exercised it, and its consequences. Analytical concepts like Max Weber's distinctions between charismatic, traditional and rational-legal authority, have been avoided. The danger of adopting them is that the themes and emphases of research material can be easily and unintentionally warped to fit the model, in the interests of tidiness and intelligibility. Instead, this study proceeds by way of a detailed and chronological examination of the major events of Te Puea's life, and an evaluation of actions and statements as they occur and in the context in which they occur. It is, in other words, a consideration of Te Puea's life in terms of her own concepts, and in relation to the Maori and wider public affairs of her day. Explanations for her behaviour are sought within the boundaries of her own life and culture rather than from the imposition of alien models.
