Submission in response to the Australian Government’s Consultation Paper on the Establishment of the Royal Commission into Institutional Responses to Child Sexual Abuse

A submission in response to the Australian Government\u27s Consultation Paper on the Establishment of the Royal Commission into Institutional Responses to Child Sexual Abuse. Introduction We are a team of academics and researchers, from the disciplines of historical studies, social work and archival science, who have substantive years of experience working on projects exploring the legacy of Australia\u27s institutional \u27care\u27 of children. Our work in this space, particularly since the release of the Forgotten Australians report in 2004, has involved ongoing engagement with a broad range of stakeholders, including care leavers, support and advocacy groups, past and current providers of out-of-home care, state and federal government departments, and cultural institutions. We welcome the opportunity to make a submission in response to the Australian Government\u27s Consultation Paper on the Establishment of the Royal Commission into Institutional Responses to Child Sexual Abuse. Our submission discusses the vital importance that records will play in this Royal Commission, with particular reference to records in the custody of past providers in religious, charitable and government sectors. We submit that records are a key issue for this Royal Commission

Agri-food trade in GTAP-HET: Returns to scale in agriculture, and the Melitz model

Agricultural protection is almost always a highly sensitive issue in bi- and multi-lateral trade negotiations. The reasons for this are usually political, but it always means there is a high demand among policy makers for analytical tools which can assess the often complex impacts of liberalisation on farm viability, land use change, and consumer food prices. Since their inception, Computable General Equilibrium (CGE) models have made a rich contribution to this analysis. However, when standard assumptions of constant returns to scale and perfect competition are used, this can limit the ability of such models to answer the questions being asked by policy makers. Put simply, these questions often amount to “what are the opportunities, and what are the threats?” If returns to scale are not constant, or if other sources of productivity variation are present in a domestic farming system, the same liberalising policy may represent an opportunity to one farmer, and a threat to another, even if the two are producing the same commodity in the same country. Combining the macroeconomic width and rigour of a CGE model with the heterogeneity of domestic farm systems represents an exciting frontier in agri-food trade policy analysis. This paper will present the current evidence on returns to scale in agricultural sectors in selected countries – drawing on fixed and variable cost share data from the USDA, and European national Farm Business Surveys collated in the Farm Accountancy Data Network (FADN). Where the evidence for increasing returns to scale is clear, it follows that there is a clear case for the importance of making use of the Melitz model, or some alternative to the standard constant returns to scale assumption

A new emphasis on root traits for perennial grass and legume varieties with environmental and ecological benefits

Grasslands cover a significant proportion of the agricultural land within the UK and across the EU, providing a relatively cheap source of feed for ruminants and supporting the production of meat, wool and milk from grazing animals. Delivering efficient animal production from grassland systems has traditionally been the primary focus of grassland‐based research. But there is increasing recognition of the ecological and environmental benefits of these grassland systems and the importance of the interaction between their component plants and a host of other biological organisms in the soil and in adjoining habitats. Many of the ecological and environmental benefits provided by grasslands emanate from the interactions between the roots of plant species and the soil in which they grow. We review current knowledge on the role of grassland ecosystems in delivering ecological and environmental benefits. We will consider how improved grassland can deliver these benefits, and the potential opportunities for plant breeding to improve specific traits that will enhance these benefits whilst maintaining forage production for livestock consumption. Opportunities for exploiting new plant breeding approaches, including high throughput phenotyping, and for introducing traits from closely related species are discussed

A route to decreasing N pollution from livestock:Use of Festulolium hybrids improves efficiency of N flows in rumen simulation fermenters

Ruminant agriculture suffers from inefficient capture of forage protein and consequential release of N pollutants to land. This is due to proteolysis in the rumen catalyzed by both microbial but initially endogenous plant proteases. Plant breeding-based solutions are sought to minimize these negative environmental impacts. The aim of this study was to perform an integrated study of rumen N metabolism using semi-continuous rumen simulation fermenters (Rusitec) to explore the extent to which swards containing Festulolium populations (interspecific hybrids between Lolium and Festuca grass species) with decreased rates of endogenous protein degradation conferred advantageous protein utilization in comparison with a National Listed perennial ryegrass. An in vitro experiment was conducted using three Festulolium hybrids (Lolium perenne × Festuca arundinacea var. glaucescens, LpFg; Lolium perenne × Festuca mairei, LpFm; and Lolium multiflorum × Festuca arundinacea var. glaucescens, LmFg) and a Lolium perenne, Lp control. LpFm and LmFg demonstrated significantly lower plant-mediated proteolysis than the control. Fresh forage was incubated in Rusitec with rumen fluid from four donor cows. Feed disappearance and production of gas, methane, and volatile fatty acids were similar across cultivars. Whereas no differences in microbial protein synthesis were noted across treatments during early fermentation (0–6 hr after feeding), an increased microbial N flow in LpFm (+30%) and LmFg hybrids (+41%) was observed during late fermentation (6–24 hr after feeding), with higher overall microbial N flows (+13.5% and + 20.2%, respectively) compared with the control (Lp). We propose an underpinning mechanism involving the partitioning of amino acid catabolism toward branched-chain amino acids and microbial protein synthesis in grasses with slow plant-mediated proteolysis instead of accumulation of rumen ammonia in grasses with fast plant-mediated proteolysis. These observations indicate the potential of Festulolium hybrids with a slow plant-mediated proteolysis trait to improve the efficiency of capture of forage protein and decrease the release of N pollutants onto the land.The authors thank the field work staff for growth and maintenance of field plots of the grass material, the staff at Trawsgoed “D‐unit” for provision of rumen fluid, Delma Jones and the staff of Analytical Chemistry for forage quality analysis, Susan Girdwood for VFA analysis, and Debbie Allen for 15N analyses.

A Formal Model Of Cognitive Processes For An Air Traffic Control Task

This document describes a formal model of the cognitive processes involved in a simplified Air Traffic Control task. The model has been developed as part of the SafeHCI project, which is investigating detection and prevention of human error in safety-critical systems. The model will serve as the basis for development of new techniques for prediction of error sources and classification of error types. This document describes the cognitive model in detail
