Prescription opioid use and employment : A nationwide Finnish register study

2021

Background: The secular decline in labor market participation and the concurrent increase in opioid use in many developed countries have sparked a policy debate on the possible connection between these two trends. We examined whether the use of prescription opioids was connected to labor market outcomes relating to participation, employment and unemployment among the Finnish population. Methods: The working-age population (aged 19–64 years) living in Finland during the period 1995–2016 was used in the analyses (consisting of 67 903 701 person-year observations). Lagged values of prescription opioid use per capita were used as the exposure. Instrumental variables (IV) estimation method was u…

Estimation of wind velocity over a complex terrain using the Generalized Mapping Regressor

2010

Abstract Wind energy evaluation is an important goal in the conversion of energy systems to more environmentally friendly solutions. In this paper, we present a novel approach to wind speed spatial estimation on the isle of Sicily (Italy): an incremental self-organizing neural network (Generalized Mapping Regressor – GMR) is coupled with exploratory data analysis techniques in order to obtain a map of the spatial distribution of the average wind speed over the entire region. First, the topographic surface of the island was modelled using two different neural techniques and by exploiting the information extracted from a digital elevation model of the region. Then, GMR was used for automatic …

Faktoru modeļu priekšrocības ekonomiskās aktivitātes īstermiņa prognozēšanā

2014

Promocijas darba anotācija Pēdējā desmitgadē Latvijas tautsaimniecības attīstība bijusi īpaši svārstīga, kas sarežģīja ekonomiskās politikas lēmumu pieņemšanu ekonomiskās situācijas stabilizēšanai. Lai atvieglotu lēmumu pieņemšanu, ekonomisko aktivitāti īstermiņā var prognozēt ar ekonometriskiem modeļiem. Promocijas darba mērķis ir novērtēt faktoru modeļu priekšrocības ekonomiskās aktivitātes prognozēšanas kontekstā un noteikt Latvijas gadījumā nepieciešamo instrumentu un metožu klāstu īstermiņa prognozēšanai. Promocijas darbā tiek sniegtas atbildes uz faktoru modeļu lietošanas problēmjautājumiem īstermiņa prognozēšanā, kā arī novērtēti daži faktoru modeļu lietošanas aspekti. Faktoru modeļu…
