A trend analysis of antimicrobial resistance in commensal Escherichia coli from several livestock species in Belgium (2011-2014) Hasselt University KU Leuven
A temporal trend analysis was performed on antimicrobial resistance data collected over 4 consecutive years (2011-2014) in the official Belgian antimicrobial resistance monitoring programme. Commensal Escherichia coli strains were isolated from faecal samples of four livestock categories (veal calves, young beef cattle, broiler chickens and slaughter pigs) and the trends of resistance profiles were analysed. The resistance prevalence remained ...
Latent risk and trend models for the evolution of annual fatality numbers in 30 European countries Hasselt University
In this paper a unified methodology is presented for the modelling of the evolution of road safety in 30 European countries. For each country, annual data of the best available exposure indicator and of the number of fatalities were simultaneously analysed with the bivariate latent risk time series model. This model is based on the assumption that the amount of exposure and the number of fatalities are intrinsically related. It captures the ...
Trend Removal in Measurements of Best Linear Time-Varying Approximations – with Application to Operando Electrochemical Impedance Spectroscopy Vrije Universiteit Brussel
Equilibria evolving over time, also called trends, are often present in ongoing measurements of real-life systems. These trends are considered as disturbances when computing the Best Linear Time-varying Approximation (BLTVA) of the system. Current techniques for dealing with trends in BLTVA measurements consist of modelling the trend with a finite number of basis functions. However, in measurements with dominant trends, the trend cannot always ...
Sinistrality is associated with (slightly) lower general intelligence: A data synthesis and consideration of the secular trend in handedness Vrije Universiteit Brussel
The relationship between the general factor of intelligence (g) and handedness is investigated using a combined sample of 23511 respondents from three large databases: the NLSY’79 (US), NLSY’97 (US) and NCDS (UK). Dextrals – those who use their right hands were found to be 1.22 IQ points higher than sinistrals (left handers) after controlling for sex and age and correcting for sources of measurement error. To see if the association between IQ ...
Impact of enclosures on range condition and trend in the semi-arid rangeland of Lake Baringo Basin, Kenya Ghent University
Geo-spatial Trend Detection through Twitter Data Feed Mining Hasselt University
Present-day Social Networking Sites are steadily progressing towards becoming representative data providers. This paper proposes TweetPos, a versatile web-based tool that facilitates the analytical study of geographic tendencies in crowd-sourced Twitter data feeds. To accommodate the cognitive strengths of the human mind, TweetPos predominantly resorts to graphical data structures such as intensity maps and diagrams to visualize (geo-spatial) ...
Nonparametric trend detection in river monitoring network data: a spatio-temporal approach Ghent University
Sportparticipatie en fysieke (in)activiteit van de Vlaamse bevolking: huidige situatie en seculaire trend (2003-2009) Vrije Universiteit Brussel
Doelstelling. Het fysieke (in)activiteitsgedrag en sportparticipatiegedrag van de Vlaamse
bevolking in kaart brengen en nagaan of er sprake is van een seculaire trend (positief of
negatief) in dit gedrag.
Methode. Er wordt nagegaan in welke mate Vlaamse jongeren en volwassenen (sportief)
actief of inactief zijn, welke sporten zij beoefenen, in welke context zij deze sporten beoefenen
en op welke manier zij zich naar ...
