Towards Personalization of Peer Review in Learning Programming
2017
Peer review is one of the effective processes for sharing knowledge and improving overall learning performance. This became more popular by the use of ICT. However, it is challenging to implement peer review in learning programming languages due to the complexity of the subject matter. A group of peer reviewers may have different overall performance but similar weaknesses on a given aspect of the programming tasks. Hence, they may not be able to help each other to address individual needs. In this paper, we present a personalized approach to peer review with consideration to criteria based assessment and individual performance on specific programming tasks. This is achieved using a novel pe…
Mapping Susceptibility to Debris Flows Triggered by Tropical Storms: A Case Study of the San Vicente Volcano Area (El Salvador, CA)
2021
In this study, an inventory of storm-triggered debris flows performed in the area of the San Vicente volcano (El Salvador, CA) was used to calibrate predictive models and prepare a landslide susceptibility map. The storm event struck the area in November 2009 as the result of the simultaneous action of low-pressure system 96E and Hurricane Ida. Multivariate Adaptive Regression Splines (MARS) was employed to model the relationships between a set of environmental variables and the locations of the debris flows. Validation of the models was performed by splitting 100 random samples of event and non-event 10 m pixels into training and test subsets. The validation results revealed an excellent (…
Prediction of debris-avalanches and -flows triggered by a tropical storm by using a stochastic approach: An application to the events occurred in Moc…
2019
Abstract Landslides are among the most dangerous natural processes. Debris avalanches and debris flows in particular have often caused casualties and severe damage to infrastructures in a wide range of environments. The assessment of susceptibility to these phenomena may help policy makers in mitigating the associated risk and thus it has attracted special attention in the last decades. In this experiment, we assessed susceptibility to debris-avalanche and -flow landslides by using a stochastic approach. Two different modeling techniques were employed: i) Multivariate Adaptive Regression Splines (MARS) and ii) Logistic Regression (LR). Both MARS and LR allow for calculating the probability …
Evaluation of debris flow susceptibility in El Salvador (CA): a comparison between Multivariate Adaptive Regression Splines (MARS) and Binary Logisti…
2018
In the studies of landslide susceptibility assessment, which have been developed in recent years, statistical methods have increasingly been applied. Among all, the BLR (Binary Logistic Regression) certainly finds a more extensive application while MARS (Multivariate Adaptive Regression Splines), despite the good performance and the innovation of the strategies of analysis, only recently began to be employed as a statistical tool for predicting landslide occurrence. The purpose of this research was to evaluate the predictive performance and identify possible drawbacks of the two statistical techniques mentioned above, focusing in particular on the prediction of debris flows. To this aim, an…

Este trabajo realiza una revisión de algunos de los programas de autor para el diseño de actividades educativas más utilizados en los centros escolares de España. Se exponen los tipos de actividades que pueden elaborarse con cada uno de los programas incluidos en la revisión, y se analizan las ventajas y limitaciones del uso de este tipo de programas en los centros educativos.
Mācību saturs un kvalitāte bioloģijas mācību priekšmetā pamatskolā
2015
Mācību saturs un kvalitāte bioloģijas mācību priekšmetā pamatskolā. Āboltiņa J., darba vadītājs Dr., prof. Geske, A. Maģistra darbs, 56 lappuses, 19 attēli, 36 literatūras avots, 6 pielikumi. Latviešu valodā. Darba mērķis ir noskaidrot kādas ir bioloģijas mācību satura problēmas pamatskolā un izstrādāt priekšlikumus bioloģijas mācību satura pilnveidei. Veikta teorētiskā literatūras avotu analīze par mācību saturu un tā izveidi. Autore izstrādājusi un veikusi skolotāju aptauju par bioloģijas mācību priekšmeta saturu 9.klasē. Apkopojot visas empīriskajā daļā iegūtās atziņas autore secināja, ka bioloģijas mācību priekšmets 9.klasē ir pārblīvēts un ieteikusi priekšlikumus tā pilnveidei.
Baltijas valstu mazo un vidējo uzņēmumu finanšu atbalsta instrumentu salīdzinājums ar Eiropas Savienības valstu praksi
2017
Bakalaura darbā ir apkopota informācija par sešu Eiropas Savienības valstu nacionālā līmeņa atbalsta programmām maziem un vidējiem uzņēmumiem (MVU). Baltijas valstu (Latvija, Lietuva un Igaunija) programmas ir apskatītas un salīdzinātās ar Eiropas Savienības “vecās” ekonomiskās zonas līdervalstu (Vācija, Francija un Lielbritānija) programmām, lai novērtētu to pielietojamību konkrētās valsts līmenī un atrast labāko un piemērotāko praksi, ko var pielietot Latvijas ekonomikas un tirgus apstākļos. Eiropas Savienības valstīs vidējais MVU procentuālais rādītājs pārsniedz 99% no visu uzņēmumu skaitļa valstīs, kas nosaka tēmas aktualitāti un nepieciešamību analizēt apkārtējo Eiropas Savienības vals…
Excited states engineering enables efficient near-infrared lasing in nanographenes
2021
The spectral overlap between stimulated emission (SE) and absorption from dark states (i.e. charges and triplets) especially in the near-infrared (NIR), represents one of the most effective gain loss channel in organic semiconductors. Recently, bottom-up synthesis of atomically precise graphene nanostructures, or nanographenes (NGs), has opened a new route for the development of environmentally and chemically stable materials with optical gain properties. However, also in this case, the interplay between gain and absorption losses has hindered the attainment of efficient lasing action in the NIR. Here, we demonstrate that the introduction of two fluoranthene imide groups to the NG core lead…
An Exploratory Research of 18 Years on the Economic Burden of Diabetes for the Romanian National Health Insurance System
2020
The prevalence of diabetes mellitus (DM) rises constantly each year worldwide. Because of that, the funds allocated for the DM treatment have increased over time. Regarding the number of DM cases, Romania is among the top ten countries in Europe. Based on the National Diabetes Programme (NDP), antidiabetic drugs and other expenditures (Self-monitoring blood glucose (SMBG) test, HbA1c, insulin pumps/insulin pumps supplies) are free of charge. This programme has undergone many changes in drugs supply, in the last two decades: re-organizing the NDP, authorization of new molecules with high prices (e.g., SGLT-2 inhibitors, etc.) or new devices (e.g., insulin pumps, etc.) The main purpose of thi…
