2014 data on water body class improvements in England, assessed against a 2009 baseline under the Water Framework Directive. The dataset includes statistical confidence and derived certainty estimates for each improvement. It was created by the Environment Agency and is now retired, superseded by a newer record.
2014 Water Framework Directive (WFD) class deteriorations at the water body level for England only. The dataset contains assessments of downgrades in class status from a 2009 baseline, including statistical confidence and derived certainty that a real deterioration occurred. It was created by the Environment Agency and is now retired, having been superseded by a newer record.
England's water body statuses for 2013, assessed under the Water Framework Directive. The dataset contains unchanged class status against a 2009 baseline, along with statistical confidence and derived certainty estimates for the lack of change. It was created by the Environment Agency and is now retired, superseded by a newer record.
Fuel sales activity statistics reported by liable fuel retailers in Queensland since the commencement of the sustainable biobased petrol mandate. The data is a statistical summary of reports submitted to the Queensland Treasury department, which notes that some retailers may have failed to report or reported inaccurately. The department is working with retailers to address identified data inaccuracies.
Historical tables present CSBFP statistical information on loans and claims since April 1, 1999. Data is broken down by province and territory, loan size, asset type, industry sector, business age, business size, borrower type, and operation type. A summary of all financial activities per fiscal year as well as revenues and expenses is also available from Innovation, Science and Economic Development Canada.
Age-standardised percentage estimates of adults aged 18+ classified as having excess weight, defined as a BMI greater than or equal to 25kg/m². The data is sourced from Public Health England's Public Health Outcomes Framework indicator 2.12 and is updated annually. It was published by Lincolnshire County Council but has been archived and is not available to the public as of January 2024.
2017 data detailing the total staff and pension expenditure for the city of Linz, Austria, broken down by budgetary item. The dataset is structured according to the Ordinance on Estimates and Clearance of Accounts (VRV) and is published by Cooperation OGD Österreich and Wikimedia Österreich under a CC-BY-4.0 license.
Personnel and pension expenditure data for the city of Linz, Austria, for the 2013 fiscal year, structured according to the Ordinance on Estimates and Clearance of Accounts (VRV). The dataset is published by Cooperation OGD Österreich and Wikimedia Österreich under a Creative Commons license. It likely contains total staff costs broken down by budgetary posts.
The Count of Traveller Caravans is a bi-annual statistical collection by the UK's Communities and Local Government department, recording the number of caravans on authorised and unauthorised sites across England. Data is collected every January and June, providing a time series at local authority, regional, and national levels. It is designated as Official Statistics, though not as National Statistics, and was previously known as the Gypsy and Traveller caravan count.
Reoffending statistics compendia is an annual publication from the UK Ministry of Justice, last updated in July 2026. It contains reoffending statistics not covered by other official publications, including breakdowns by disposal type and offender type. The dataset is designated as Official Statistics and is published under the OGL-UK-3.0 license.
Alberta municipalities annually submit financial and statistical information via standardized returns. The data likely contains summaries of audited financial statements, including assets, liabilities, revenue, expenses, long-term debt, and property taxes, alongside municipal statistics like population, assessment, and tax rates. The dataset is compiled by the Government of Alberta and was last updated on July 8, 2026.
Christian Lebière's thesis at Carnegie Mellon University presents an integrated computational model of cognitive arithmetic using the ACT-R architecture. The model simulates human error and latency patterns in arithmetic tasks, analyzing results through separate simulations, a lifetime learning simulation, and formal parameter analysis. It provides a unifying account of cognitive arithmetic results and explores implications for teaching.
A study by Bryce McLaughlin of Columbia University investigates fairness in machine-assisted human decision systems. The work includes a formal statistical model and a lab experiment examining how properties of machine predictions affect human decisions. The findings suggest that excluding protected group information from predictions may fail to reduce, or even increase, ultimate disparities.
10,000 redistricting simulations for North Carolina and Georgia's congressional districts validate Bayesian Improved Surname Geocoding (BISG) methods. The dataset includes voter lists necessary for estimating individual race via BISG, created by John Curiel of MIT. It supports testing the viability of probabilistic versus plurality race assignment methods for redistricting.
A research paper from the University of Toronto presents optimization techniques for business-intelligence queries using order dependencies (ODs). The work evaluates these techniques using an implementation in IBM DB2 V10 with the TPC-DS benchmark schema and IBM customer-inspired queries. Experimental results demonstrate significant performance gains, and the paper includes a polynomial-time algorithm for testing logical implication of ODs.
A NSW Government technical paper from data.gov.au describes a mathematical model for determining the path swept by a vehicle when turning. The method reportedly describes vehicular swept paths with an error of less than half of one percent and includes graphical examples. The paper discusses practical applications of the method for vehicle path prediction.
Project 3.8 of the NESP Tropical Water Quality Hub addresses steps to develop a cost-effective integrated monitoring program for the Long Term Sustainability Plan. The project identifies environmental, social, and economic indicators and evaluates existing monitoring programs, including the AIMS Long Term and Marine Monitoring Programs. The dataset was published by the Australian Ocean Data Network and last updated in July 2026.
Geoscience Australia's Marine Samples Database provides seabed sand content data from samples extracted in August 2010. The dataset was used to compare 18 spatial interpolation methods, including RFIDS and RFOK, across three regions of the Australian Exclusive Economic Zone (AEEZ). This study offers guidelines for improving spatial interpolations of marine environmental data.
2008/09 to 2012/13 data on learner participation and achievement in Further Education and Skills in England and the UK. The dataset includes information from the Labour Force Survey on the highest qualification held and details on vocational qualifications awarded. It is provided by the Skills Funding Agency and was last updated on 2026-07-08.
Georgios Papageorgiou developed a collection of MCMC algorithms and processing functions for Bayesian non- and semi-parametric models. The software implements methods for single and multivariate response regression, joint mean-covariance modeling, and Dirichlet process mixtures, as documented in multiple peer-reviewed publications. The code is associated with research from Wuhan University and is available under an Open Access (gold) license.
