Converging currents: Governance of Living Waters in the West Kimberley, Australia.
Creators: name: Taylor, Kat
Publisher: name: The Australian National University
Year: 2020

description: Water colonialism is embedded in Australia's water governance frameworks. Decades of Australian water reforms have failed to address this water justice issue. In this thesis, I (lead researcher Kat Taylor) partnered with Walalakoo Aboriginal Corporation (WAC) representing Nyikina and Mangala peoples, in the West Kimberley, Western Australia. WAC has strong expertise and interest in water. A participatory action research orientation was underpinned by critical research theory, with attention to decolonising methodologies. The exploratory research had two objectives. First, to apply a water colonial lens to critique discourses about water governance, policy and security. Second, to outline water policy/governance options that work towards water decolonisation and/or address gaps in WA's water governance model. A variety of methods were used, including; discourse analyses, small group discussions and policy development, with a focus on 'reframing' and 'envisioning' after Smith 1999. A key goal of the discourse analysis was to contrast the body of policy work undertaken by First Peoples with the corresponding Australian Government engagement (or lack thereof). Unpacking the concept of 'water security' indicated that opaque, incoherent framings within national policy implicitly excluded First Peoples' rights and interests. Water colonialism is also embedded in international 'best practice' guidelines, such as the OECD 12 Principles on Water Governance, which fail to harmonise with the United Nations Declaration on the Rights of Indigenous Peoples. The findings in the thesis provide further evidence of the structural nature of water colonialism, and pinpoint specific areas of tension between settler state and First Peoples' discourses about water. A key goal of outlining alternative water governance frameworks is to mitigate those tensions by developing water policy options that articulate WAC's position while responding to the WA state government's current water governance framework. WAC's framework of cultural (co-)governance for Living Waters and strategies towards water decolonisation provide potential policy pathways forward. Bringing together theoretical and applied findings, this thesis provides novel insights with implications for the future of water reform in Australia.
Mini-Workshop: Mathematical Foundations of Isogeometric Analysis

description: Isogeometric Analysis (IgA) is a new paradigm which is designed to merge two so far disjoint disciplines, namely, numerical simulations for partial differential equations (PDEs) and applied geometry. Initiated by the pioneering 2005 paper of one of us organizers (Hughes), this new concept bridges the gap between classical finite element methods and computer aided design concepts. Traditional approaches are based on modeling complex geometries by computer aided design tools which then need to be converted to a computational mesh to allow for simulations of PDEs. This process has for decades presented a severe bottleneck in performing efficient simulations. For example, for complex fluid dynamics applications, the modeling of the surface and the mesh generation may take several weeks while the PDE simulations require only a few hours. On the other hand, simulation methods which exactly represent geometric shapes in terms of the basis functions employed for the numerical simulations bridge the gap and allow from the beginning to eliminate geometry errors. This is accomplished by leaving traditional finite element approaches behind and employing instead more general basis functions such as B-Splines and Non-Uniform Rational B-Splines (NURBS) for the PDE simulations as well. The combined concept of Isogeometric Analysis (IgA) allows for improved convergence and smoothness properties of the PDE solutions and dramatically faster overall simulations. In the last few years, this new paradigm has revolutionized the engineering communities and triggered an enormous amount of simulations and publications mainly in this field. However, there are several profound theoretical issues which have not been well understood and which are currently investigated by researchers in Numerical Analysis, Approximation Theory and Applied Geometry.
'Baby Sitter': The Transformation of Domestic Care Work in Indonesia
Creators: name: Nasution, Gita
Publisher: name: The Australian National University
Year: 2020

description: The baby sitter is a new caring occupation in urban Indonesia, and a transformation of an older form of home-based labour performed by domestic workers. The baby sitter is a quasi-professional worker, providing a new and different model of care from that previously provided by kinship-based individuals or unregulated domestic workers. The baby sitter is also a live-in child carer in for middle-class and affluent families in Indonesia. The occupation borrows the Western term 'babysitter' to invoke an idea of modern child care methods. The appearance of the baby sitter in uniform is a distinctive mark of the current market-based care regime. The new occupation has been developed by private agencies that recruit, train and contract young, educated, rural women who aspire to be a baby sitter. The agencies have developed services for training and certifying the baby sitter by drawing upon their pre-existing programmes mandated by the government for overseas workers. This thesis seeks to understand what the baby sitter means for Indonesian society, specifically, how social relations are shaped by and actively shape the baby sitter role. Based on twelve months of ethnographic fieldwork in Jakarta, Indonesia, I analyse the perspectives of different groups concerned with the baby sitter as an occupation (especially the baby sitter, the parent-employer, and the agency) and bring it into the wider social, economic and historical context. I argue that while the baby sitter displays a transformation of domestic and care work in Indonesia along with rapid social and economic transformation, gender and class inequalities persist. The baby sitter, I suggest, supports rather than challenges the reproduction of these inequalities. This thesis begins with a discussion of the differences and similarities between the baby sitter and another category of domestic worker locally known as an Mbak (a Javanese term also used to refer to older sister), to describe current child care practices in urban households. It is followed by a discussion of the social and economic context in which the baby sitter as an occupation has emerged. The growing trend for hiring a baby sitter, driven by the urban economy, provides increasing opportunities for rural to urban migrants. The trained and certified baby sitter matches busy middle-class parents' desire for good quality care for their children. The agencies make this professionalisation of the baby sitter possible while perpetuating the hierarchy of class in the society.
Documentation Cultures: Arnhem Land 1935-2015
Creators: name: Lane, Robert Lazarus
Publisher: name: The Australian National University
Year: 2019

description: Ceremonial activity has always been a form of documentation for Yolngu-the Indigenous people of north-east Arnhem Land in the Northern Territory of Australia. Drawing on ethnography and archival research, I aim to show the intergenerational and cross-cultural role played by persistent documentation practices. My analysis is based on embedded fieldwork undertaken in Arnhem Land between 2008 and 2015. An ethnographic approach is combined with archival research to examine documentation produced by a range of Yolngu people between 1935 and 2015. I argue, Yolngu approaches to documentation drives knowledge management locally and shapes cross-cultural projects, creating a mass of documents that reflects a documentary agency. Previous research on ceremonial activity, and ritual practices more broadly, has not explicitly addressed the ways in which knowledge is performed as documentation. This research enables a culturally inflected view of documentation that provides a different perspective on the ways in which media and performance is used as a means of acting in the world. Each chapter includes a discussion of Yolngu engagement with documentary production, and the examination of documentary evidence selected from the archive. These multiple perspectives frame my analysis of performance and ceremony as documentation in the context of ritual, educational, artistic, legal and political action.
Selection models for publication bias in meta-analysis. Presentation at ESMARConf2021
Creators: name: Viechtbauer, Wolfgang

Year: 2021
Subjects: Uncategorized

description: The non-replicability of certain findings in various disciplines has brought further attention to the problem that the published literature - which predominantly forms the evidence basis of research syntheses - may not be representative of all research that has been conducted on a particular topic. More specifically, concerns have been raised for a long time that statistically significant findings are overrepresented in the published literature, a phenomenon usually referred to as publication bias, which in turn can lead to biased conclusions. Various methods have been proposed in the meta-analytic literature for detecting the presence of publication bias, estimating its potential impact, and correcting for it. So-called selection models are among the most sophisticated methods for this purpose, as they attempt to directly model the selection process. If a particular selection model is an adequate approximation for the underlying selection process, then the model provides estimates of the parameters of interest (e.g., the average true effect and the amount of heterogeneity in the true effects) that are 'corrected' for this selection process (i.e., they are estimates of the parameters in the population of studies before any selection has taken place). In this talk, I will briefly describe a variety of models for this purpose and illustrate their application with the metafor package in R.
Dynamic meta-analysis: Providing evidence to guide local decisions using a global evidence base. Presentation at ESMARConf2021
Creators: name: Martin, Philip

Year: 2021
Subjects: Uncategorized

description: Traditionally meta-analysis presents a set of statistical analyses for a large body of literature, providing a global answer. However, people who use evidence often want answers that address relatively local contexts. For example, a meta-analysis of interventions for managing invasive plant species might find that herbicides are highly effective, but a practitioner may wish to know about the effects of glyphosate on Japanese knotweed, an answer they cannot get from the original hypothetical meta-analysis. In this talk, I will introduce our solution to this problem using a new website and Shiny app, metadataset.com. This tool allows users to easily choose outcomes and interventions of interest to them and then filter or weight data before running a bespoke meta-analysis. The aim is to make analyses as relevant to user needs as possible. We call this process ‘dynamic meta-analysis.’ During the talk I will run through an example of the tools use and highlight areas in which we want to engage with the wider evidence synthesis community.

description: We present a study of large-scale bars in field and cluster environments out to redshifts of ~0.8 using a final sample of 945 moderately inclined disk galaxies drawn from the EDisCS project. We characterize bars and their host galaxies and look for relations between the presence of a bar and the properties of the underlying disk. We investigate whether the fraction and properties of bars in clusters are different from their counterparts in the field. The total optical bar fraction in the redshift range z=0.4-0.8 (median z=0.60), averaged over the entire sample, is 25% (20% for strong bars). For the cluster and field subsamples, we measure bar fractions of 24% and 29%, respectively. We find that bars in clusters are on average longer than in the field and preferentially found close to the cluster center, where the bar fraction is somewhat higher (~31%) than at larger distances (~18%). These findings however rely on a relatively small subsample and might be affected by small number statistics. In agreement with local studies, we find that disk-dominated galaxies have a higher optical bar fraction (~45%) than bulge-dominated galaxies (~15%). This result is based on Hubble types and effective radii and does not change with redshift. The latter finding implies that bar formation or dissolution is strongly connected to the emergence of the morphological structure of a disk and is typically accompanied by a transition in the Hubble type.

description: The topological recursion is an ubiquitous structure in enumerative geometry of surfaces and topological quantum field theories. Since its invention in the context of matrix models, it has been found or conjectured to compute intersection numbers in the moduli space of curves, topological string amplitudes, asymptotics of knot invariants, and more generally semiclassical expansion in topological quantum field theories. This workshop brought together mathematicians and theoretical physicists with various background to understand better the underlying geometry, learn about recent advances (notably on quantisation of spectral curves, topological strings and quantum gauge theories, and geometry of moduli spaces) and discuss the hot topics in the area.

Three different kinds of periodic cylindrical surfaces and a special closed cylindrical surface are obtained. Using the elliptic functions contained in \emph{mathematic}, we find that this periodic shape has the minimal total energy for one period when the period-amplitude ratio $β\simeq1.477$, and point out that it is a discontinuous deformation between plane and this periodic shape.

description: Superconducting gravimeters are the most sensitive instruments to measure surface gravity changes at low frequencies. Currently, about twenty five superconducting gravimeters are operating in the world and their global network has been developed. We investigate possible applications of the superconducting gravimeters to tests of gravitational physics. Previous experimental searches for spatial anisotropies in the gravitational constant G and for gravitational waves, performed with gravimeters in 1960's to 1970's, can be improved by applications of the current superconducting gravimeters. Also, we describe other proposed applications of testing the universality of free-fall and searching for composition-dependent dilatonic waves, and discuss future works necessary for these geophysical tests.

Method for determining total proton reaction cross sections
Creators: name: Hojvat, Carlos Federico
Publisher: name: University of British Columbia
Year: 2011

description: Measurements of total proton reaction cross sections by the beam-attenuation method involve determinations of the number of protons removed from the incident beam by an absorber compared to those transmitted. This work presents an adaptation of the associated particle technique to enable total reaction cross section measurements for the 15.8 MeV protons from the ³He(d,p)⁴He reaction. A thick heavy ice target is bombarded with 600-keV³ He particles. The ⁴He particles are detected in a silicon surface-barrier detector, and the protons, after traversing the absorber, in a CsI scintillation counter. Both the spatial collimation and the time of arrival of the proton are defined by the detection of the associated ⁴He particle. Thus, removal of a proton from the proton "beam" is identified by an anticoincidence between the ⁴He and proton counters, whereas proton transmission is identified by a coincidence. The limitations and applications of the technique are presented, as well as a discussion of the critical portions of the experimental design.
title: Sixteenth-century courtship in the diocese of Canterbury
Creators: name: O'Hara, Diana
Publisher: name: University of Kent
Year: 2021

description: This thesis seeks to re-examine the nature of courtship in the sixteenth century, using church court and probate material for the diocese of Canterbury. Challenging the hitherto established views regarding the freedom and personal initiative exercised by courting couples, it explores important topics neglected in most previous studies. Essentially it revives the notion that courtship in the past possessed far more structure and coherence than has been granted recently, and argues that the decision to marry was a momentous one, conducted against a backdrop of constraints and expectations which did much to determine and shape individual choice. Some constraints were external to the principle actors. Chapter 1 argues that parents, kin and community played a number of decisive roles in the making of marriage and Chapter 2 shows how courtship was structured by the giving and receiving of gifts, each invested with their own symbolic meaning. Go-betweens, as Chapter 3 demonstrates, played an important role in mediating between couples, transmitting gifts and messages, and helping in the vital property negotiations. Chapter 4 reveals a great deal more about the constraints of locality and distance over courtship behaviour. Couples possessed relatively restricted geographical horizons which delineated the parameters of their choices and they courted at particular times and in special places. Those intent on marriage, as argued in Chapter 5, also carried a range of internalized assumptions, which, together with legal and social rules may have helped to determine the time thought appropriate to marry. Finally, in Chapter 6, the crucial importance of financial matters in the process of courtship is examined. It demonstrates that even for the relatively humble, the sixteenth century was one of rapid dowry inflation, something that further determined prospects in the matrimonial market. Few marriages took places without negotiations or calculations about future financial prospects and the present value of the bride's contribution to the union.

description: We study the classical and quantum models of a Friedmann-Robertson-Walker (FRW) cosmology, coupled to a perfect fluid, in the context of the $f(R)$ gravity. Using the Schutz' representation for the perfect fluid, we show that, under a particular gauge choice, it may lead to the identification of a time-parameter for the corresponding dynamical system. Moreover, this formalism gives rise to a Schrödinger-Wheeler-DeWitt (SWD) equation for the quantum-mechanical description of the model under consideration, the eigenfunctions of which can be used to construct the wavefunction of the Universe. In the case of $f(R)=R^2$ (pure quadratic model), for some particular choices of the perfect fluid source, exact solutions to the SWD equation can be obtained and the corresponding results are compared to the usual $f(R)=R$ model.

Recycling of Air Pollution Control Residues Into Engineered Lightweight Aggregates
Creators: name: Chamorro Bolanos, Ximena
Publisher: name: University of East London
Year: 2023

description: The thermal treatment of Municipal Solid Waste (MSW) is continuously increasing in the UK as a sustainable practice to reduce the amount of waste that is sent to landfills and to recover energy in Energy from Waste (EfW) facilities. However, an issue associated with this practice is the volatilisation of hazardous compounds contained in the waste. These contaminants are removed from the gaseous emissions by air pollution control units before the gases are released into the environment. The solid wastes generated during this cleaning process are known as air pollution control residues (APCr) and are classified as hazardous because of their environmental impact associated with their chemical composition and leaching properties. APCr treatment before landfilling can be highly expensive, and therefore, there is a need for recycling these waste materials. The aim of this research was to investigate the viability of incorporating APCr into the manufacture of lightweight aggregates (LWA).
 
In the first stage, APCr samples collected from different EfW facilities across the UK were characterised for elemental composition, mineralogy and leaching properties. In the second stage, a mix composed of all samples of APCr previously characterised was prepared for the evaluation of APCr treatment. Washing with water and accelerated carbonation were optimised to reduce the leaching properties of APCr. The third stage comprised the manufacture of artificial LWA, through hot bonding and cold bonding processes at a laboratory scale. The physical and technological characteristics of the manufactured LWA were assessed for the fulfilment of the corresponding standards for LWA as well as compared with those of the commercial products Lytag® and Carbon8®. It was demonstrated that the hot-bonded LWA exhibited better technological characteristics and improved leaching properties compared with the cold-bonded LWA.
 
In the final stage, hot-bonded and cold-bonded LWA were incorporated into lightweight concrete (LWAC) to evaluate their performance. The LWAC made of hot-bonded LWA containing 25% washed APCr, was strong enough for applications in structural concrete exposed to different environmental conditions. Also, this LWAC formulation showed a reduction in the carbon emissions associated with its production, which represents an important environmental benefit. A future scale-up of LWA manufacture from 25% of washed APCr can significantly reduce the amount of APCr that is currently sent to landfills and increase the recycling rates of this waste material.

description: Analysis of high spatial resolution VLA images shows that the free-free emission from NGC7538 IRS1 is dominated by a collimated ionized wind. We have re-analyzed high angular resolution VLA archive data from 6 cm to 7 mm, and measured separately the flux density from the compact bipolar core and the extended (1.5" - 3") lobes. We find that the flux density of the core is proportional to the frequency to the power of alpha, with alpha being about 0.7. The frequency dependence of the total flux density is slightly steeper with alpha = 0.8. A massive optically thick hypercompact core with a steep density gradient can explain this frequency dependence, but it cannot explain the extremely broad recombination line velocities observed in this source. Neither can it explain why the core is bipolar rather than spherical, nor the observed decrease of 4% in the flux density in less than 10 years. An ionized wind modulated by accretion is expected to vary, because the accretion flow from the surrounding cloud will vary over time. BIMA and CARMA continuum observations at 3 mm show that the free-free emission still dominates at 3 mm. HCO+ J = 1 - 0 observations combined with FCRAO single dish data show a clear inverse P Cygni profile towards IRS1. These observations confirm that IRS1 is heavily accreting with an accretion rate of about 2 times 10(-4) solar masses per year.

description: In two-dimensional quantum site-percolation square lattice models, the von Neumann entropy is extensively studied numerically. At a certain eigenenergy, the localization-delocalization transition is reflected by the derivative of von Neumann entropy which is maximal at the quantum percolation threshold $p_q$. The phase diagram of localization-delocalization transitions is deduced in the extrapolation to infinite system sizes. The non-monotonic eigenenergies dependence of $p_q$ and the lowest value $p_q\simeq0.665$ are found. At localized-delocalized transition points, the finite scaling analysis for the von Neumann entropy is performed and it is found the critical exponents $ν$ not to be universal. These studies provide a new evidence that the existence of a quantum percolation threshold $p_q<1$ in the two-dimensional quantum percolation problem.

description: In this research work, Fe3O4@DABA-PA-CuBr2 nanocomposite was fabricated by a simple and inexpensive method by immobilizing copper(II) bromide on the surface of magnetic nanoparticles modified with 3,4-diaminobenzoic acid and picolinic acid. Deep eutectic solvents or DESs are green and environmentally friendly solvents that are used as catalyst or solvent in many reactions. The utilization of Fe3O4@DABA-PA-CuBr2 nanocatalyst in ChCl–Urea at 100 °C presented an attractive, environmentally benign and highly efficient catalytic system for the preparation of a broad range of diaryl sulfones through one-pot three-component coupling of aryl iodides, aryl boronic acids, and DABSO (as SO2 source). It should be noted that the Fe3O4@DABA-PA-CuBr2 catalyst was used several times without significant reduction of the catalytic activity. VSM, TEM, and ICP-OES analysis of the reused Fe3O4@DABA-PA-CuBr2 catalyst after eight cycles revealed that that the structure, magnetic property, shape, and size of the particles did not change significantly.
The Use of Micropropagated Founder Material with Top-down Irrigation: A Novel Approach for Sphagnum Farming in a Lowland Environment
Creators: name: Clough, Jack
Publisher: name: University of East London
Year: 2024

description: Paludiculture is the cultivation of wetland crops on rewetted peat soils. It represents a new agricultural paradigm offering solutions to peatland degradation by restoring Ecosystem Services (ES) and maintaining land productivity. Sphagnum moss is a paludiculture crop, produced via Sphagnum farming (SF), which has several uses, particularly peat replacement in growing media. 

The conventional SF approach uses the Moss Layer Transfer Technique (MLTT) to provide founder material from a donor site with surface irrigation via raised water tables. This method is challenging in the UK lowland agricultural context as donor Sphagnum sites are scarce, and there is reluctance to raise water levels within a conventional agricultural landscape. 

This thesis presents a novel alternative SF option, the Micropropagated-Irrigation-From-Above ‘MIFA’ approach. Micropropagated Sphagnum requires very small amounts of donor material and overhead irrigation removes the need for active water table management, removing some current SF challenges. 

The effectiveness of the MIFA approach on Sphagnum hydrology and growth was monitored across three pilot studies and two experimental field sites in the UK via hydrological and growth measurements. 

Sphagnum water availability was assessed via pore water pressure (PWP) measurements. Across the field sites, the MIFA approach resulted in PWP measurements broadly equivalent to literature values for natural peatland systems and better than those recorded for a drained peatlands capable of supporting Sphagnum growth. 

Sphagnum growth was assessed up to 24 months post-establishment via Terrestrial Laser scanning (TLS), with Sphagnum carpet height increases of up to 16cm recorded. Suggesting in some cases, growth under the MIFA approach was comparable or better than Sphagnum grown under conventional SF approach.

The results demonstrate that the MIFA approach produces a good Sphagnum crop across two contrasting sites, offering a viable alternative to the MLTT approach for Sphagnum farming in areas where the conventional SF approach is problematic.
Network meta-analysis with netmeta - Present and Future. Presentation at ESMARConf
Creators: name: Schwarzer, Guido
Publisher: name: figshare
Year: 2021
Subjects: Uncategorized

description: Network meta-analysis is a more recent development that provides methods to combine direct and indirect evidence and thus constitutes an extension of pairwise meta-analysis for combining the results from studies that used different comparison groups (Salanti, 2012). R package netmeta (Rücker et al., 2020) implements a frequentist approach for network meta-analysis based on graph-theoretical methods (Rücker, 2012) and is one of the most popular R packages for network meta-analysis. Main objective of netmeta is to provide a comprehensive set of R functions for network meta-analysis in a user-friendly implementation.
In this presentation, we will give a brief overview of implemented methods in netmeta as well as planned future extensions.

Probing the Primordial Power Spectrum with Cluster Number Counts

description: We investigate how well galaxy cluster number counts can constrain the primordial power spectrum. Measurements of the primary anisotropies in the cosmic microwave background (CMB) may be limited, by the presence of foregrounds from secondary sources, to probing the primordial power spectrum at wave numbers less than about 0.30 h Mpc^{-1}. We break up the primordial power spectrum into a number of nodes and interpolate linearly between each node. This allows us to show that cluster number counts could then extend the constraints on the form of the primordial power spectrum up to wave numbers of about 0.45 h Mpc^{-1}. We estimate combinations of constraints from PLANCK and SPT primary CMB and their respective SZ surveys. We find that their constraining ability is limited by uncertainties in the mass scaling relations. We also estimate the constraint from clusters detected from a SNAP like gravitational lensing survey. As there is an unambiguous and simple relationship between the filtered shear of the lensing survey and the cluster mass, it may be possible to obtain much tighter constraints on the primordial power spectrum in this case.

description: Southern Ocean shortwave radiation biases of up to 40 Wm-2 in summer are common in general circulation models, with misrepresentation of cloud identified as the major cause. We evaluate the atmospheric component GA7.0 and GA7.1 of the HadGEM3 general circulation model and the MERRA-2 reanalysis, and find that GA7.0 and GA7.1 underestimate the reflected top of atmosphere shortwave radiation, while MERRA-2 overestimates this quantity. Using a dataset of ship ceilometer and radiosonde observations we evaluate cloud cover and link it to the thermodynamic profile. We find low cloud below 2 km and fog predominant and cloud cover exceeding 90% in most regions. We show that this cloud is strongly linked to boundary layer stability and sea surface temperature. Using a ground-based lidar simulator we produce virtual ceilometer measurements along the voyage tracks for a 1:1 comparison with the ceilometer measurements. We find that GA7.0 and MERRA-2 underestimate cloud cover by 18–25%, especially cloud below 1 km and fog. While the boundary layer stability is well represented in GA7.0 and MERRA-2, the link between the boundary layer stability and cloud found in observations is not present in the models, pointing to deficiencies in the subgrid scale parametrisation of cloud.

description: In the non-relativistic theory of gravity recently proposed by Horava, the Hamiltonian constraint is not satisfied locally at each point in space. The absence of the local Hamiltonian constraint allows the system to have an extra dark-matter-like component as an integration constant. We discuss consequences of this fact in the context of cosmological perturbations, paying a particular attention to the large scale evolution of the curvature perturbation. The curvature perturbation is defined in a gauge invariant manner with this ``dark matter'' taken into account. We then clarify the conditions under which the curvature perturbation is conserved on large scales. This is done by using the evolution equations.
