Memories of Early Years and Other Writings

Douglas Lilburn’s Scottish-born father, a successful settler farmer, said of his son’s chosen profession, ‘If it had to be music, couldn’t it have been bagpipes?’[i] Lilburn, described by a memorial plaque in Christchurch as ‘the father of New Zealand music’, contemplated becoming a writer if his musical compositions had fallen on deaf ears. He showed early promise when a Christmas poem written for a Wanganui Chronicle competition won second prize and 10 shillings, just after his 12th birthday.

Next Generation Very Large Array Memo No. 6, Science Working Group 1: The Cradle of Life

This paper discusses compelling science cases for a future long-baseline interferometer operating at millimeter and centimeter wavelengths, like the proposed Next Generation Vary Large Array (ngVLA). We report on the activities of the Cradle of Life science working group, which focused on the formation of low- and high-mass stars, the formation of planets and evolution of protoplanetary disks, the physical and compositional study of Solar System bodies, and the possible detection of radio signals from extraterrestrial civilizations. We propose 19 scientific projects based on the current specification of the ngVLA. Five of them are highlighted as possible Key Science Projects: (1) Resolving the density structure and dynamics of the youngest HII regions and high-mass protostellar jets, (2) Unveiling binary/multiple protostars at higher resolution, (3) Mapping planet formation regions in nearby disks on scales down to 1 AU, (4) Studying the formation of complex molecules, and (5) Deep atmospheric mapping of giant planets in the Solar System. For each of these projects, we discuss the scientific importance and feasibility. The results presented here should be considered as the beginning of a more in-depth analysis of the science enabled by such a facility, and are by no means complete or exhaustive.Comment: 51 pages, 12 figures, 1 table.

Computer simulations show that Neanderthal facial morphology represents adaptation to cold and high energy demands, but not heavy biting

Three adaptive hypotheses have been forwarded to explain the distinctive Neanderthal face: (i) an improved ability to accommodate high anterior bite forces, (ii) more effective conditioning of cold and/or dry air and, (iii) adaptation to facilitate greater ventilatory demands. We test these hypotheses using three-dimensional models of Neanderthals, modern humans, and a close outgroup (Homo heidelbergensis), applying finite-element analysis (FEA) and computational fluid dynamics (CFD). This is the most comprehensive application of either approach applied to date and the first to include both. FEA reveals few differences between H. heidelbergensis, modern humans, and Neanderthals in their capacities to sustain high anterior tooth loadings. CFD shows that the nasal cavities of Neanderthals and especially modern humans condition air more efficiently than does that of H. heidelbergensis, suggesting that both evolved to better withstand cold and/or dry climates than less derived Homo. We further find that Neanderthals could move considerably more air through the nasal pathway than could H. heidelbergensis or modern humans, consistent with the propositions that, relative to our outgroup Homo, Neanderthal facial morphology evolved to reflect improved capacities to better condition cold, dry air, and, to move greater air volumes in response to higher energetic requirements

Massive star formation and feedback in W49A: The source of our Galaxy's most luminous water maser outflow

We present high spatial resolution mid-IR images of the ring of UCHII regions in W49A obtained at Gemini North, allowing us to identify the driving source of its powerful H2O maser outflow. These data also confirm our previous report that several radio sources in the ring are undetected in the mid-IR because they are embedded deep inside the cloud core. We locate the source of the water maser outflow at the position of the compact mid-IR peak of source G (source G:IRS1). This IR source is not coincident with any identified compact radio continuum source, but is coincident with a hot molecular core, so we propose that G:IRS1 is a hot core driving an outflow analogous to the wide-angle bipolar outflow in OMC-1. G:IRS1 is at the origin of a larger bipolar cavity and CO outflow. The water maser outflow is orthogonal to the bipolar CO cavity, so the masers probably reside near its waist in the cavity walls. Models of the IR emission require a massive protostar of 45Msun, 3e5Lsun, and an effective envelope accretion rate of 1e-3Msun/yr. Feedback from the central star could potentially drive the H2O maser outflow, but it has insufficient radiative momentum to have driven the large-scale CO outflow, requiring that this massive star had an active accretion disk over the past 10^4 yr. Combined with the spatialy resolved morphology in IR images, G:IRS1 in W49 provides compelling evidence for a massive protostar that formed by accreting from a disk, accompanied by a bipolar outflow.Comment: 14 pages, MNRAS accepte

Multi-domain quantitative recovery following Radical Cystectomy for patients within the iROC (Robot Assisted Radical Cystectomy with intracorporeal urinary diversion versus Open Radical Cystectomy) Randomised Controlled Trial: The first 30 patients

Many patients develop complications after radical cystectomy (RC) [1]. Reductions in morbidity have occurred through centralisation and technical improvements [2], and perhaps through robot-assisted RC (RARC). Whilst RARC is gaining popularity, there are concerns about oncological safety [3] and extracorporeal reconstruction [4], and randomised controlled trials (RCTs) find little difference [5]. We are conducting a prospective RCT comparing open RC and RARC with mandated intracorporeal reconstruction (Robot-assisted Radical Cystectomy with intracorporeal urinary diversion versus Open Radical Cystectomy [iROC] trial) [6]

Potential use of APSIS-InSAR measures of the range of vertical surface motion to improve hazard assessment of peat landslides

Peat landslides represent a notable natural hazard that is difficult to assess across complex blanket bog terrain. To aid the assessment of peat landslide susceptibility, we propose a new metric, the range of vertical surface motion (RVSM), quantified from time series data of surface motion measured using interferometric synthetic aperture radar (InSAR). Our expectation is that areas that are more susceptible to landslide will display a high RVSM that is indicative of high amplitude swelling and shrinking of the peat in response to changes in the volume of water stored in the peat over time. To test our hypothesis we examined the spatial distribution of high RVSM values that preceded three peat landslides in Ireland in 2020 and over a large area of blanket bog. We observed that high RVSM was closely associated with the known failures and with inferred points of initial failure, and that the areas of high RVSM were detectable up to two years in advance of failure. In the blanket bog landscape, high RVSM was associated with areas where landscape hydrology would favour thick peat and subsequent potential instability. We conclude that RVSM mapping has potential for refining national-scale assessments of peat landslide susceptibility

The Small Politics of Everyday Life: Local History Society Archives and the Production of Public Histories

Thousands of small, private archives sit in attics, cupboard, church halls and computer hard drives around the country; they are the archives of local history societies. Simultaneously freed from the control of archives sector and government initiatives, and yet saturated with local peculiarities and biases, local history society archives can seem to be the very antithesis of the wider archives movement, apparently private and parochial, undemocratic and uncatalogued. Consequently, local history society archives are rarely included in ‘the politics of the archive’ discussions. But if the activity of archiving is to be understood as a political act, what are the politics and meanings of local history and their archives? In this article, I suggest that certain types of local history society archive collections can help us paint a picture of the everyday lives of working-class people in Britain in the twentieth century. They detail the small politics of people’s lives – family, work, leisure, and beliefs. They give ordinary people a name, a face, and a life lived. Moreover, the workings of local history society archives raise important questions about historical production, for these groups play a significant role in rescuing and preserving archival collections, and in creating and curating their own histories

A new age of believing women? Judging rape narratives online

Book synopsis: This book critically examines the last few decades of discussion around sex and violence in the media, on social media, in the courtroom and through legislation. The discursive struggles over what constitutes "sexual violence", "victims" and "offenders" is normally determined through narratives: a selective ordering of events and participants. Centrally, the book investigates the social processes involved in the telling of stories of rape and its political implications. From a multidisciplinary feminist perspective, this volume explores what narratives about sexual violence are deemed legitimate at this historical juncture. This volume brings together feminist scholars working in a wide variety of disciplines including law, legal studies, history, gender studies, ethnology, media, criminology and social work from across the globe. Through situated empirical work, these scholars seek to understand currents movements between the criminal justice system and the cultural imagination
