Information supply in the era of mass digitisation

Information Supply in the era of mass digitization Drawing on his experience at the Bodleian Library and now at the British Library, Ronald Milne will share his first-hand impressions of 'boutique' and mass digitization programmes, such as those being undertaken by Google and Microsoft, and their effect on information supply. Collections define libraries. What does this mean in the 21st Century? Will all libraries become equal as the digital revolution progresses? What might the digitization and indexing of millions of works mean for university researchers and the intellectually curious more generally? What are the benefits and what are the strategic issues that we are bound to consider

Standardization of mine accounting

His paper presents the history of the international efforts to standardize mine accounting between 1895 and 1915. Extractive industries, such as mining and oil and gas, posed especially difficult problems for the accounting profession. In 1895 there was almost no literature to help in the resolution of these problems. During this following interval the issues of mine accounting were thoroughly discussed and limited standardization was achieved in some regions. Near the end of this period the Institution of Mining and Metallurgy unanimously adopted a set of accounting standards for the mining industry

Herbert C. Hoover: Accounting influences on his life

Herbert C. Hoover was arguably the most distinguished mining engineer in American history. During the early part of this century he enjoyed great success as a consultant and mine manager. He was regarded as one of the most skilled practitioners of his day. In addition, he was a regular contributer to the mining journals and wrote several books, two of which became classics (Principles of Mining and De Re Metallica, an annotated translation of the works of Agricola). The rationalization of management was an important theme in his life. He frequently turned to accounting as a means to improve management systems. This paper describes several of the more interesting stories concerning the role accounting played in Hoover\u27s early life

Does enternal nutrition affect clinical outcome? A systematic review of the randomized trials

Background: Both parenteral nutrition (PN) and enteral nutrition (EN) are widely advocated as adjunctive care in patients with various diseases. A systematic review of 82 randomized controlled trials (RCTs) of PN published in 2001 found little, if any, effect on mortality, morbidity, or duration of hospital stay; in some situations, PN increased infectious complication rates. Objective: To assess the effect of EN or volitional nutrition support (VNS) in individual disease states from available randomized controlled trials (RCTs). Design: We conducted a systematic review. RCTs comparing EN or VNS to untreated controls, or comparing EN to PN, were identified and separated according to the underlying disease state. Meta-analysis was performed when at least 3 RCTs provided data. The evidence from the RCTs was summarized into one of five grades. A or B indicated the presence of strong or weak (low quality RCTs) evidence supporting the use of the intervention. C indicated a lack of adequate evidence to make any decision about efficacy. D indicated that limited data could not support the intervention. E indicated either that strong data found no effect, or that either strong or weak data suggested that the intervention caused harm. Patients and settings: RCTs could include either hospitalized or non-hospitalized patients. The EN or VNS had to be provided as part of a treatment plan for an underlying disease process. Interventions: The RCT had to compare recipients of either EN or VNS to controls not receiving any type of artificial nutrition or had to compare recipients of EN with recipients of PN. Outcome measures: Mortality, morbidity (disease-specific), duration of hospitalization, cost, or interventional complications. Summary of grading: A – No indication was identified. B – EN or VNS in the perioperative patient or in patients with chronic liver disease; EN in critically ill patients or low birth weight infants (trophic feeding); VNS in malnourished geriatric patients. (The low quality trials found a significant difference in survival favoring the VNS recipients in the malnourished geriatric patient trials; two high quality trials found non-significant differences that favored VNS as well.) C – EN or VNS in liver transplantation, cystic fibrosis, renal failure, pediatric conditions other than low birth weight infants, well-nourished geriatric patients, non-stroke neurologic conditions, AIDS; EN in acute pancreatitis, chronic obstructive pulmonary disease, non-malnourished geriatric patients; VNS in inflammatory bowel disease, arthritis, cardiac disease, pregnancy, allergic patients, preoperative bowel preparation D – EN or VNS in patients receiving non-surgical cancer treatment or in patients with hip fractures; EN in patients with inflammatory bowel disease; VNS in patients with chronic obstructive pulmonary disease E – EN in the first week in dysphagic, or VNS at any time in non-dysphagic, stroke patients who are not malnourished; dysphagia persisting for weeks will presumably ultimately require EN. Conclusions: There is strong evidence for not using EN in the first week in dysphagic, and not using VNS at all in non-dysphagic, stroke patients who are not malnourished. There is reasonable evidence for using VNS in malnourished geriatric patients. The recommendations to consider EN/VNS in perioperative/liver/critically ill/low birth weight patients are limited by the low quality of the RCTs. No evidence could be identified to justify the use of EN/VNS in other disease states

Implementing e-legal deposit: a British Library perspective

An account of progress since 2004, from the enabling legislation provided by the U.K. Legal Deposit Libraries Act, towards secondary legislation through which deposit of electronic and other non-print material can commence. We focus on the work of the independent Legal Deposit Advisory Panel, the six legal deposit libraries in the British Isles and the publishers, with particular examples of working practice drawn from the British Library

Facilitating the elicitation of beliefs for use in Bayesian Belief modelling

Expert opinion is increasingly being used to inform Bayesian Belief Networks, in particular to define the conditional dependencies modelled by the graphical structure. The elicitation of such expert opinion remains a major challenge due to both the quantity of information required and the ability of experts to quantify subjective beliefs effectively. In this work, we introduce a method designed to initialise conditional probability tables based on a small number of simple questions that capture the overall shape of a conditional probability distribution before enabling the expert to refine their results in an efficient way. These methods have been incorporated into a software Application for Conditional probability Elicitation (ACE), freely available at https://github.com/KirstyLHassall/ACE Hassall (2019

ECOSSE: Estimating Carbon in Organic Soils - Sequestration and Emissions: Final Report

Background Climate change, caused by greenhouse gas ( GHG) emissions, is one of the most serious threats facing our planet, and is of concern at both UK and devolved administration levels. Accurate predictions for the effects of changes in climate and land use on GHG emissions are vital for informing land use policy. Models which are currently used to predict differences in soil carbon (C) and nitrogen (N) caused by these changes, have been derived from those based on mineral soils or deep peat. None of these models is entirely satisfactory for describing what happens to organic soils following land-use change. Reports of Scottish GHG emissions have revealed that approximately 15% of Scotland's total emissions come from land use changes on Scotland's high carbon soils; the figure is much lower for Wales. It is therefore important to reduce the major uncertainty in assessing the carbon store and flux from land use change on organic soils, especially those which are too shallow to be deep peats but still contain a large reserve of C. In order to predict the response of organic soils to external change we need to develop a model that reflects more accurately the conditions of these soils. The development of a model for organic soils will help to provide more accurate values of net change to soil C and N in response to changes in land use and climate and may be used to inform reporting to UKGHG inventories. Whilst a few models have been developed to describe deep peat formation and turnover, none have so far been developed suitable for examining the impacts of land-use and climate change on the types of organic soils often subject to land-use change in Scotland and Wales. Organic soils subject to land-use change are often (but not exclusively) characterised by a shallower organic horizon than deep peats (e.g. organo-mineral soils such as peaty podzols and peaty gleys). The main aim of the model developed in this project was to simulate the impacts of land-use and climate change in these types of soils. The model is, a) be driven by commonly available meteorological data and soil descriptions, b) able to simulate and predict C and N turnover in organic soils, c) able to predict the impacts of land-use change and climate change on C and N stores in organic soils in Scotland and Wales. In addition to developing the model, we have undertaken a number of other modelling exercises, literature searches, desk studies, data base exercises, and experimentation to answer a range of other questions associated with the responses of organic soils in Scotland and Wales to climate and land-use change. Aims of the ECOSSE project The aims of the study were: To develop a new model of C and N dynamics that reflects conditions in organic soils in Scotland and Wales and predicts their likely responses to external factors To identify the extent of soils that can be considered organic in Scotland and Wales and provide an estimate of the carbon contained within them To predict the contribution of CO 2, nitrous oxide and methane emissions from organic soils in Scotland and Wales, and provide advice on how changes in land use and climate will affect the C and N balance In order to fulfil these aims, the project was broken down into modules based on these objectives and the report uses that structure. The first aim is covered by module 2, the second aim by module 1, and the third aim by modules 3 to 8. Many of the modules are inter-linked. Objectives of the ECOSSE project The main objectives of the project were to: Describe the distribution of organic soils in Scotland and Wales and provide an estimate of the C contained in them Develop a model to simulate C and N cycling in organic soils and provide predictions as to how they will respond to land-use, management and climate change using elements of existing peat, mineral and forest soil models Provide predictive statements on the effects of land-use and climate change on organic soils and the relationships to GHG emissions, including CO 2, nitrous oxide and methane. Provide predictions on the effects of land use change and climate change on the release of Dissolved Organic Matter from organic soils Provide estimates of C loss from scenarios of accelerated erosion of organic soils Suggest best options for mitigating C and N loss from organic soils Provide guidelines on the likely effects of changing land-use from grazing or semi-natural vegetation to forestry on C and N in organic soils Use the land-use change data derived from the Countryside Surveys of Scotland and Wales to provide predictive estimates for changes to C and N balance in organic soils over time

Defining the cognitive phenotype of autism

Although much progress has been made in determining the cognitive profile of strengths and weaknesses that characterise individuals with autism spectrum disorders (ASDs), there remain a number of outstanding questions. These include how universal strengths and deficits are; whether cognitive subgroups exist; and how cognition is associated with core autistic behaviours, as well as associated psychopathology. Several methodological factors have contributed to these limitations in our knowledge, including: small sample sizes, a focus on single domains of cognition, and an absence of comprehensive behavioural phenotypic information. To attempt to overcome some of these limitations, we assessed a wide range of cognitive domains in a large sample (N = 100) of 14- to 16-year-old adolescents with ASDs who had been rigorously behaviourally characterised. In this review, we will use examples of some initial findings in the domains of perceptual processing, emotion processing and memory, both to outline different approaches we have taken to data analysis and to highlight the considerable challenges to better defining the cognitive phenotype(s) of ASDs. Enhanced knowledge of the cognitive phenotype may contribute to our understanding of the complex links between genes, brain and behaviour, as well as inform approaches to remediation
