title: Novel six-coordinate Aryl- and Alkyltin  complexes

authors: Lloyd, Nicholas C.

subjects: chemistry

abstract: Organo-tin compounds have wide applications as pesticides and as intermediates for organic synthesis.¹ They are invariably Sn(IV) derivatives and are generally four-coordinate.² The mixed organo/chioro compounds of the type RnSnCI4-n do however have the ability to expand their coordination numbers to five or six. This depends critically on the substituents - with four organic groups, R₄Sn, there is no tendency at all to coordinate extra ligands, while at the other extreme SnCl₄ readily forms six-coordinate [SnC1₄L₂] complexes since the electronegative halo groups increase the Lewis acidity of the tin centre.

title: Principal Professional Learning in New Zealand:  How does it happen?  Understanding the value of profound professional learning for experienced principals

authors: Graham, Arnna Rosa

subjects: lead learner

abstract: Profound professional learning for principals makes a difference to student achievement.  While indirect, the impact of effective principal practice has a ripple effect throughout the community of learners of a school.  The principal is, and should be, the lead learner of the school.  Authenticity in this action brings credibility.  This credibility establishes the principal as a significant role model.

This qualitative research provides some insight to the understanding and practices of experienced effective principals and their professional learning in a New Zealand context.  The findings suggest that there are measures of effectiveness for New Zealand principals, however ascertaining what to measure is somewhat difficult.  Knowledge of tools to support the identification of learning needs is limited and therefore not significant in the practice of these principals.  

Drivers and barriers to professional learning are identifiable.  Work/life balance is highlighted as both a measure of effectiveness and a filter for professional learning.  This is one of many filters explored.

Recognition is given to the positioning of New Zealand principalship in a post-modern paradigm and the conflict that arises when measures of neo-liberal accountabilities are employed.  

The significance of school context and culture are highlighted as conditions for profound professional learning.   The culture of traditional learning through principal clusters is challenged. Recommendations and considerations are offered to both principal colleagues and the Ministry of Education as a result of these findings.  These include the need for principal mentoring and secondment to external, national bodies as part of professional learning for all principals.  The value of professional learning is highlighted.  

More significantly principals are challenged to embrace and develop an authentic culture of professional learning.

title: Arts Festival: 'Moonwalking Backwards Into The Future: "Poi E", Music Video and Documentary'

authors: Perrott, Lisa

subjects: Art

abstract: Research presentation - an audiovisual presentation drawing upon my published research (book chapter: 'Moonwalking Backwards Into The Future: "Poi E", Music Video and Documentary'). This presentation presented a Matuaranga Maori perspective of the temporal travels of music video and documentary, framed by the concept of whakapap. This presentation took place as part of a panel of 4 presenters who represented Te Kura Toi at the Arts Festival during the University of Waikato Open Day, 2023. This was an oral presentation, which included projected slides and videos from a PPT presentation. The audience included prospective students, their teachers and family members, community members, and current students and academic staff from the University of Waikato. My presentation was documented and photographed.
