BBC Radio 3 - Free Thinking - Running
No full textWe've been running for two million years give or take. Shahidha Bari and Laurence Scott explore contemporary running as solitary inspiration and communal activity with the Geographer and 1999 Scottish Hill Running Champion, Hayden Lorimer, the artists Kai Syng Tan and Angus Farquhar, and the literary scholar and bare-foot artiste, Vybarr Cregan-Reid. Conversation ranges from feeling empowered on city streets to teaming up with the wind to the horrid history of the treadmill and explore whether Running deserves better representation in the arts.

Comparison of Cliff-Lorimer-Based Methods of Scanning Transmission Electron Microscopy (STEM) Quantitative X-Ray Microanalysis for Application to Silicon Oxycarbides Thin Films
No full textIn this work, we compare the results of different Cliff-Lorimer (Cliff & Lorimer 1975) based methods in the case of a quantitative energy dispersive spectrometry investigation of light elements in ternary C-O-Si thin films. To determine the Cliff-Lorimer (C-L) k-factors, we fabricated, by focused ion beam, a standard consisting of a wedge lamella with a truncated tip, composed of two parallel SiO2 and 4H-SiC stripes. In 4H-SiC, it was not possible to obtain reliable k-factors from standard extrapolation methods owing to the strong CK-photon absorption. To overcome this problem, an extrapolation method exploiting the shape of the truncated tip of the lamella is proposed herein. The k-factors thus determined, were then used in an application of the C-L quantification procedure to a defect found at the SiO2/4H-SiC interface in the channel region of a metal-oxide field-effect-transistor device. As in this procedure, the sample thickness is required, a method to determine this quantity from the averaged and normalized scanning transmission electron microscopy intensity is also detailed. Monte Carlo simulations were used to investigate the discrepancy between experimental and theoretical k-factors and to bridge the gap between the k-factor and the Watanabe and Williams ζ-factor methods (Watanabe & Williams, 2006)
The discovery and significance of fast radio bursts
No full textIn 2007 we were part of a team that discovered the so-called ``Lorimer
Burst'', the first example of a new class of objects now known as fast radio
bursts (FRBs). These enigmatic events are only a few ms in duration and occur
at random locations on the sky at a rate of a few thousand per day. Several
thousand FRBs are currently known. While it is now well established that they
have a cosmological origin, and about 10\% of all currently known sources have
been seen to exhibit multiple bursts, the origins of these enigmatic sources
are currently poorly understood. In this article, we review the discovery of
FRBs and present some of the highlights from the vast body of work by an
international community. Following a brief overview of the scale of the visible
Universe in \S 1, we describe the key moments in radio astronomy (\S 2) that
led up to the discovery of the Lorimer burst (\S 3). Early efforts to find more
FRBs are described in \S 4 which led to the discovery of the first repeating
source (\S 5). In \S 6, as we close out on the second decade of FRBs, we
outline some of the many open questions in the field and look ahead to the
coming years where many surprises are surely in store.Comment: 23 pages, 9 figures, accepted for publication in Astrophysics and

Memoirs for the Earth: Jacquetta Hawkes's literary experiments in deep time
No full textThis article is concerned with the narration of earth processes in stories of a younger world. It centres on A Land (1951), the most notable published work of Jaquetta Hawkes, archaeologist, prehistorian, writer and journalist. The land under examination is Britain, and its island story becomes her story too. The book unfolds as an unconventional geological history of regional scenery, prehistoric life and rock formations that is at the same time an impressionistic portrayal of self through the ecstatic physical apprehension of earth forces and environmental fields. For Hawkes the storyteller, mineral memories and body memories are unlocked in tandem. This article shows how such an experimental narrative is enabled through unexpected temporal shifts, suggesting a continuum of consciousness across diverse life forms, and explores the cultural conditions, psychological theories and personal circumstances that served to inspire Hawkes the author. In the closing stages of the article, the author enters into the spirit of Hawkes’s narrative style, featuring as protagonist as well as commentator

ISBS 2018 AUCKLAND CONFERENCE SPRINZ SPORT AND EXERCISE BIOMECHANICS TEACHING ARCHIVE PROGRAMME
No full textThe host of the archive is the J.E. Lindsay Carter Kinanthropometry Clinic and Archive (JELCKCA) at the Auckland University of Technology. The director of the Archive is Professor Patria Hume (AUT SPRINZ) and archive web master is Dr Anna Lorimer (Bond University and AUT SPRINZ).
Initiation of this project was a result of planning and hosting the 36th Annual Conference of the International Society of Biomechanics in Sports (ISBS) in Auckland, New Zealand September 10-14, 2018.
This archive is a place to share (upload) and obtain (download) electronic image files that are intended for non-profit instructional use in sport and exercise biomechanics classes and educational outreach programs (e.g. National Biomechanics Day). Archive images are indented to be stand-alone instructional slides or can be photo/images/graphics that illustrate biomechanical data, principles, theories, or application. While human sport and exercise examples are preferred, any animal biomechanical images of potential interest and instructional value are welcome.
