title: Addressing the climate crisis: An action plan for psychologists (summary)

authors: APA Task Force on Climate Change

abstract: Psychologists have conducted valuable work on the climate crisis and can make even greater contributions to understanding the crisis, mitigating and adapting to climate change, and achieving climate justice. This summary of the report from the American Psychological Association’s (APA) Task Force on Climate Change examines the multiple roles psychologists play in research, practice, education, advocacy, and communications related to the climate crisis and how APA can facilitate expansion of psychologists’ work in these domains. The task force recommends that APA pursue a set of activities that will both (a) strengthen the field by encouraging a larger number of psychologists, across all specializations, to work on climate change, and (b) broaden the impact of psychologists’ work on climate change by supporting their engagement and collaborations with other fields and sectors. Further, the task force offers recommendations for how APA can help mitigate climate change by improving its own energy use and sustainability practices and encouraging improvements by other organizations and the public.

title: Preparation of buta-1,3-diynyl complexes of platinum(II) and their use in the construction of neutral molecular squares: synthesis, structural and theoretical characterisation of cyclo-{Pt(µ-C≡CC≡C)(dppe)}₄ and related chemistry

authors: Bruce, Michael I.

subjects: Chemistry

abstract: Copper(I)-catalysed reactions of cis-PtCl₂(L)₂ (L = Pet₃, L₂= dppe, dppp) with buta-1,3-diyne have given the corresponding diynyl complexes, cis-Pt(C≡CC≡CH)2(L)2 (L = Pet₃ 1, L₂= dppe 2, dppp 3) whose solid-state structures have been determined from single crystal X-ray diffraction studies. Theoretical calculations were carried out to probe the electronic structure of these diynyl complexes. Complex 2 reacts with Co₂(CO)₈ to give a bis-adduct 5 and with Ru₃(µ-dppm)(CO)₁₀ to give a mono-adduct 6; in both, the least hindered C≡C triple bond(s) is(are) coordinated. Lithiation (LiBut) of 2 gives a dilithio derivative, which has been converted to dimethyl 7 or mono-SiMe₃ 8 or -Au(PPh₃) 9 complexes. Cu(I) and Ag(I) (MI) adducts ( tweezer  complexes) have been obtained from reactions of 2 with MISCN or [MI(NCMe)₄]⁺. An ES mass spectrometric study of the interactions of 2 with Group 1 cations and with Tl⁺ is also described; comparative experiments with {W(CO)₃Cp}₂(µ-C₈), in which the four C≡C triple bonds do not have a  tweezer  conformation, have also been carried out. The degree of association is determined by the competitive solvation of the Group 1 cation. Coupling of the buta-1,3-diynyl complexes with Pt(OTf)₂(L )₂ gives homo- or mixed-ligand molecular squares cyclo-{(L)₂Pt(µ-C CC C)₂Pt(L )₂}₂ (L, L = Pet₃, L₂, L ₂= dppe, dppp; not all combinations), of which the molecular structure of cyclo-{Pt(µ-C CC C)(dppe)}₄ 17 is described (as solvates containing dmso). The molecular squares form adducts with substituted ammonium triflates [NH₂R₂][OTf] (R = Et, Pri, Cy; NH₂R₂= dbuH) and with Group 11 cations [MI(NCMe)]⁺.

title: Huikau

authors: Maxwell, Te Kahautu

abstract: Huikau is dedicated to my life long mentor and educator Mrs Ema Rogers who imparted her knowledge of Te Haahi Ringatū and things Māori to me. She housed me for months while I reseearched my MA Thesis Te Kōpura. Mrs Rogers passed away in December 2012. This new composition was performed by Ōpōtiki Mai Tawhiti Kapa Haka at the Mātaatua Regional Kapa Haka Competition. This composition placed first in the Waiata Tira category.
