title: Education for practice in a hybrid space: Enhancing professional learning with mobile technology by Franziska Trede, Lina Markauskaite, Celina McEwen, Susie Macfarlane [Review]

authors: Zegwaard, Karsten E.

abstract: This book is the third in a series on Understanding Teaching-Learning Practice. This series is focuses on publishing research on the intertwining relationship of how practice informs research which subsequently informs practice. The series is particularly focused on student-centered contextualized learning where the learning is enabled through real-world application. Two earlier publications in this series are Playing the PhD Game with Integrity (2019) by J.A. Bowden and P. J. Green, and Spaces of Teaching and Learning (2018) by R.A. Ellis and P. Goodyear

title: Studies on polygermanyl-transition metal (carbonyl) derivatives

authors: Wong, Fook Sin

abstract: The compounds Ge₂ H₅Mn(CO)₅, Ge₂H₅Co(CO)₄ (Ge₂H₅)₂Fe(CO)₄, Ge₃H₇Mn(CO)₅, [GeH₂Mn(CO)₅] ₂ and [GeH₂Co(CO)₄] ₂ have been prepared by alkali-halide elimination reactions between the appropriate polygermanyl halides and metal carbonyl anions. 
The characterisation by infrared, Raman, n.m.r. and mass spectrometry of these compounds is discussed in detail. The physical properties and reactions have also been investigated and compared, in parallel with the parent polygermanes. Reagents used include hydrogen halides, group IV metal halides, mercuric halides and Na/NH₃ solution. Most of the reactions were studied by n.m.r. spectroscopy and the intermediates and products further characterised.
Transition metal exchange is shown to be a useful synthetic route to yield the unsymmetric iron compound Ge₂H₅(GeH₃)Fe(CO)₄ and possibly GeH₃ (SiH₃)Fe(CO)₄.
The polygermanyl-transition metal carbonyl derivatives are shown to be more stable than the germyl analogues and reasons, with spectroscopic evidence, are discussed.

title: Artefacts, biology and bias in museum collection research

authors: Wehi, Priscilla M.

subjects: experimenta design

abstract: Museum collections are increasingly subjected to scientific scrutiny, including molecular, isotopic and trace-element analyses. Recent advances have extended analyses from natural history specimens to historical artefacts. We highlight three areas of concern that can influence interpretation of data derived from museum collections: sampling issues associated with museum collection use, methods of analysis, and the value of cross-referencing data with historical documents and data sets. We use a case study that focuses on kiwi (Apteryx spp.) feather samples from valuable 19th century Māori cloaks in New Zealand to show how sampling and analysis challenges need to be minimized by careful design. We argue that aligning historical records with scientific data generated from museum collections significantly improves data interpretation.
