Aktīvas runas attīstības sekmēšana trīsgadīgiem bērniem mūsdienu izglītības tendenču kontekstā
2019
Kvalifikācijas darbs izstrādāts par tematu “Aktīvas runas attīstības sekmēšana trīsgadīgiem bērniem mūsdienu izglītības tendenču kontekstā.” Temata aktualitāte saistīta ar apstākli, ka ar 2019.gada septembri stājas spēkā jaunais izglītības saturs – kompetenču izglītība, kurā uzsvars likts uz lietpratības, patstāvības un sadarbības prasmju veidošanu. Tas nav iespējams bez bērnu aktīvās runas attīstības. Tādēļ nepieciešams aktualizēt jautājumus, kā pirmsskolas skolotāji var veiksmīgi attīstīt bērnu runu, adaptējot uzkrāto pedagoģisko pieredzi jaunā izglītības satura prasībām. Pētījuma mērķis ir teorētiski pētīt un empīriski pamatot kompetenču pieejas efektivitāti aktīvās runas sekmēšanā trīsg…

Trīsgadīgu bērnu pieklājīgas uzvedības paradumu pilnveide lomu rotaļās
2018
Bakalaura darba autore ir Ilze Dzidruma, temats ir “Trīsgadīgu bērnu pieklājīgas uzvedības paradumu pilnveide lomu rotaļās”. Uzvedības kultūra ir cilvēku sabiedrības kultūras neatņemama sastāvdaļa. Mūsdienās, ļoti aktuāla ir bērnu nepieklājīga uzvedība. Vecāki ir pārāk aizņemti darbos, lai pievērstu bērnam uzmanību un iemācītu pieklājīgas uzvedības normas, kaut arī ir ļoti svarīgi ģimenei iesaistīties bērna audzināšanā. Pirmie dzīves gadi ir paši svarīgākie bērna dzīvē, kad tiek apgūta pasaule sev apkārt. Bērns vēro sev tuvos cilvēkus un mācās no redzētā. Pieklājīgas uzvedības normas trīs gadu vecumā bērnam var iemācīt ar rotaļu palīdzību, vecāku mīlestība un atbalstu. Bakalaura darbs sastā…
Assessing long-term fiscal developments : a new approach
2011
We use a new approach to assess long-term fiscal developments. By analyzing the time-varying behaviour of the two components of government spending and revenue – responsiveness and persistence–, a feature not captured by automatic stabilisers, we are able to infer about the sources of fiscal deterioration (improvement). Drawing on quarterly data, we estimate recursively these components within a system of government revenue and spending equations using a Three-Stage Least Square method for eight European Union countries plus the US. The results suggest that significant changes in the fiscal stance (including those related to the current crisis) are reflected in the estimates of persistence …
Intrauterine growth restriction and congenital malformations: a retrospective epidemiological study
2013
Background: Intrauterine growth restriction (IUGR) and small for gestational age (SGA) birth have been considered possible indicators of the presence of malformations. The aim of this study is to evaluate such relationships in a population of newborns, along with other epidemiological and auxological parameters, in particular the ponderal index (PI). Methods: We analyzed the birth data of 1093 infants, classified according to weight for gestational age as SGA, appropriate for gestational age (AGA) or large for gestational age (LGA). The prevalence of malformations was analyzed in relation to weight percentile at birth and SGA birth, maternal smoking, pregnancy diseases and PI. Results: Our …
Intrauterine growth pattern and birthweight discordance in twin pregnancies: a retrospective study
2013
Background: Twins, compared to singletons, have an increased risk of perinatal mortality and morbidity, due mainly to a higher prevalence of preterm birth and low birthweight. Intrauterine growth restriction (IUGR) is also common and can affect one or both fetuses. In some cases, however, one twin is much smaller than the other (growth discordance). Usually, high birthweight discordance is associated with increased perinatal morbidity. The aim of this study is to describe the epidemiological features of a population of twins at birth, with particular reference to the interpretation and clinical effects of birthweight discordance. Methods: We evaluated retrospectively the clinical features o…
Fuzzy green vehicle routing problem for designing a three echelons supply chain
2020
Abstract In this study, a three-echelon fuzzy green vehicle routing problem (3E-FGVRP) is considered for designing a regional agri-food supply chain on a time horizon. To account for the variability associated with the quantities requested by customers, it is assumed that the demands are fuzzy numbers simulated by a time-dependent algorithm. Moreover, the vehicle fleet and distribution centres are considered with a defined capacity. The credibility theory of fuzzy sets is used to implement a multi-objective fuzzy chance-constrained programming model, where the total costs and carbon emissions are minimised. The resolution of the 3E-FGVRP is conducted by using a non-dominated sorting genetic…
Multiobjective optimization of building energy consumption and thermal comfort based on integrated BIM framework with machine learning-NSGA II
2022
Detailed parametric analysis and measurements are required to reduce building energy usage while maintaining acceptable thermal conditions. This research suggested a system that combines Building Information Modeling (BIM), machine learning, and the non-dominated sorting genetic algorithm-II (NSGA II) to investigate the impact of building factors on energy usage and find the optimal design. A plugin is developed to receive sensor data and export all necessary information from BIM to MSSQL and Excel. The BIM model was imported to IDA Indoor Climate and Energy (IDA ICE) to execute an energy consumption simulation and then a pairwise test to produce the sample data set. To study the data set a…
