title: The effect of irrigation on cadmium, uranium, and phosphorus contents in agricultural soils

authors: Salmanzadeh, Mahdiyeh

subjects: Cadmium

abstract: Cadmium (Cd) is a toxic metal which has accumulated in New Zealand agricultural soils due to phosphate fertilizer application. Understanding the contribution of plant uptake or leaching of Cd to observed Cd losses from soil is important. The concentration and distribution of Cd in irrigated and unirrigated soils with the same phosphate fertilizer history were investigated. Twenty-two pairs of soil samples from four depths (0–0.1, 0.1–0.2, 0.2–0.3 and 0.3–0.4 m) were taken from irrigated and unirrigated areas in the same field on dairy farms in three regions of New Zealand. The mean concentration of Cd at depths of 0–0.1 m and 0.1–0.2 m, as well as the cumulative masses of Cd (0–0.2, 0–0.3 and 0–0.4 m) in unirrigated soils were significantly higher (P < 0.05) than in irrigated soils. The concentration of phosphorus (P) at all depths (except for 0.2–0.3 m), as well as the cumulative mass of P in all depths of unirrigated soils, was also significantly higher (P < 0.05) than irrigated soils. However, no significant difference was detected in the concentrations of uranium (U) between irrigated and unirrigated soils. Irrigation induced a ∼7% Cd loss from topsoil (0–0.1 m), with the average rate of Cd loss from the top 0.1 m (due to irrigation) being 2.3 g ha⁻¹ yr⁻¹. This study therefore confirms that irrigation can enhance Cd mobilization, however Cd is mainly adsorbed to the surface soil.

title: Developing an inter-university partnership: The importance of relationally-connected leaders

authors: Ferrier-Kerr, Jenny L.

abstract: We have been involved in an inter-university partnership that supports, contributes to, and influences our own and others’ thinking and actions. As we have collaborated on teaching, learning, and research in the field of educational leadership, we recognise that we have developed our own leadership practice and created opportunities for others to do so. The partnership in which academics and students from the University of Central Oklahoma and the University of Waikato have been participating has evolved as a flexible and innovative endeavor over an eighteen month period. In this relatively brief time, we have discovered there are considerable possibilities for the partnership to be developed in a number of ways that will benefit academics, students, and our respective institutions. In this paper, we examine and discuss the findings generated by our initial inquiry as we seek to make sense of our inter university partnership in order to sustain and progress it. Our leadership during the initial phases of the partnership appears to have been a key element in its success. We have found that the presence of a relational connectedness has influenced and enhanced our own leadership practice and subsequently the quality of the partnership. It has enabled us to facilitate the growth of a community of practice and generate academic collaboration.

title: Coaching for the game of life: Driving coaching with mana

authors: Were, Brandyn Māia

subjects: Kaupapa Māori

abstract: Coaching needs to account for culture. This indigenous autoethnography explores personal experience to show how I, a young Māori male coach in Aotearoa New Zealand, navigates the complex nature of coaching. By weaving together Kaupapa Māori, established coaching knowledge, and experiences from my playing and coaching journey to date, a Kaupapa Māori coaching framework emerges – Driving Coaching with Mana.

As I reflect on the teachings of my coach, Mr. Mel Young, combined with my cultural identity, I reconnect to critical moments in my life that have shaped the person I am today and the values I hold, elevating the centrality of culture through the practice of Kaupapa, Ako, Manaakitanga, Whanaungatanga, Wairuatanga, and self-reflection as Āta-kaiako (a reflective coach).

Driven to enhance the development of rangatahi (youth) through sport, and informed by literature and experience, Driving Coaching with Mana is personally and culturally grounded – a way of thinking about coaching differently and in a more holistic way. There is more to the people we coach than their lives as athletes. Coaching is more than skill acquisition.
