Comparison of different uncertainty techniques in urban stormwater quantity and quality modelling

2011

Abstract Urban drainage models are important tools used by both practitioners and scientists in the field of stormwater management. These models are often conceptual and usually require calibration using local datasets. The quantification of the uncertainty associated with the models is a must, although it is rarely practiced. The International Working Group on Data and Models, which works under the IWA/IAHR Joint Committee on Urban Drainage, has been working on the development of a framework for defining and assessing uncertainties in the field of urban drainage modelling. A part of that work is the assessment and comparison of different techniques generally used in the uncertainty assessm…

Uncertainty estimation of a complex water quality model: The influence of Box–Cox transformation on Bayesian approaches and comparison with a non-Bay…

2012

Abstract In urban drainage modelling, uncertainty analysis is of undoubted necessity. However, uncertainty analysis in urban water-quality modelling is still in its infancy and only few studies have been carried out. Therefore, several methodological aspects still need to be experienced and clarified especially regarding water quality modelling. The use of the Bayesian approach for uncertainty analysis has been stimulated by its rigorous theoretical framework and by the possibility of evaluating the impact of new knowledge on the modelling predictions. Nevertheless, the Bayesian approach relies on some restrictive hypotheses that are not present in less formal methods like the Generalised L…

Handling Underdispersion in Calibrating Safety Performance Function at Urban, Four-Leg, Signalized Intersections

2011

Poisson basic assumption of equidispersion is often too much restrictive for crash count data; in fact this type of data has been found to often exhibit overdispersion. Underdispersion has been less commonly observed, and this is the reason why it has been less convenient to model directly than overdispersion. Overdispersion and underdispersion are not the only issues that can be a potential source of error in specifying statistical models and that can lead to biased crash-frequency predictions; these issues can derive from data properties (temporal and spatial correlation, time-varying explanatory variables, etc.) or from methodological approach (omitted variables, functional form selectio…

Wood energy production, sustainable farming livelihood and multifunctionality in Finland

2012

Abstract Climate change and the projected depletion of fossil energy resources pose multiple global challenges. Innovative technologies offer interesting possibilities to achieve more sustainable outcomes in the energy production sector. Local, decentralized alternatives have the potential to sustain livelihoods in rural areas. One example of such a venture has emerged around heating businesses in rural Finland, and is referred to as heat entrepreneurship. Heat entrepreneurship entails a system where a local forest owner, usually a farmer, provides heat to a small community or local building, such as a school. Heat is produced using local forest resources that would otherwise be unutilized.…

Alternated estimation in semi-parametric space-time branching-type point processes with application to seismic catalogs

2014

An estimation approach for the semi-param-etric intensity function of a class of space-time point processes is introduced. In particular we want to account for the estimation of parametric and nonparametric components simultaneously, applying a forward predictive likelihood to semi-parametric models. For each event, the probability of being a background event or an offspring is therefore estimated.

Kognitīvās funkcijas normatīvi veseliem bērniem, bērniem ar CSWS sindromu un citiem epilepsijas traucējumiem

2021

Šajā darbā ir apskatītas kognitīvās funkcijas, kurās ietilpst atmiņa, uzmanība, uztvere, vadības funkcijas un valoda, kā arī plašāk apskatīta epilepsija, tās ārstēšana, CSWS sindroms (epilepsija ar nepārtrauktiem smailajiem viļņiem miega laikā), kā arī epilepsijas saistība ar kognitīvajām funkcijām un UDHS (uzmanības deficīta un hiperaktivitātes sindroms). Šī pētījuma mērķis un uzdevums ir izprast un izzināt, vai bērniem ar CSWS sindromu un citiem epilepsijas traucējumiem vizuālās uzmanības, vizuālās un verbālās darba atmiņas, uztveres, vadības un motoro funkciju līmeņi tiek prognozēti zemāki, vai būs izteiktākas uzvedības problēmas, īpaši agresivitāte un hiperaktivitāte, kā arī, vai būs iz…

Estimation of ordered response models with sample selection

2011

We introduce two new Stata commands for the estimation of an ordered response model with sample selection. The opsel command uses a standard maximum-likelihood approach to fit a parametric specification of the model where errors are assumed to follow a bivariate Gaussian distribution. The snpopsel command uses the semi-nonparametric approach of Gallant and Nychka (1987, Econometrica 55: 363–390) to fit a semiparametric specification of the model where the bivariate density function of the errors is approximated by a Hermite polynomial expansion. The snpopsel command extends the set of Stata routines for semi-nonparametric estimation of discrete response models. Compared to the other semi-n…

Rural livelihood diversification: a solution for poverty in the post‐Soviet rural Baltic states?

2019

This article analyses rural livelihood diversification through a longitudinal follow‐up survey, that targets former collective farm workers in Estonia, Latvia and Lithuania. It argues, that between 1995 and 2010 the former collective farm workers employed three distinct livelihood diversification strategies in order to create their living. A wage‐based livelihood diversification strategy, which does not include any agricultural practices, was more common among the better‐off households. A farm‐based livelihood diversification strategy, which does not rely on salaries, was more often employed by the poor. A mixed strategy, that combines both wage income and farm activities, was used by both …
