Developing a Method for Measuring Science and Technology Oriented Creativity (STOC)
2021
Abstract The article contains the results of a research within the STIMEY (Science, Technology, Innovation, Mathematics, Engineering for the Young) project funded by the European Union’s Horizon-2020 research and innovation program (2016-2021). In the project, a hybrid learning environment (LE) was developed for both on-site and online learning suitable for the learning conditions in the COVID-19 era and beyond. The purpose of the research segment presented in this paper was to develop an instrument for assessment of the learner’s progress in creativity as one of the key targets of STIMEY. COVID-19 has shown that creativity is also needed to allow education systems the flexibility for unexp…
Suite of Statistical Models Forecasting Latvian GDP
2014
Abstract We develop a suite of statistical models to forecast Latvian GDP. We employ various univariate and multivariate econometric techniques to obtain short-term GDP projections and to assess the performance of the models. We also comprise the information contained in components of GDP and obtain short-term GDP projections from disaggregated perspective. We run out-of-sample forecasting procedures to evaluate GDP projections and to assess forecasting accuracy of all individual statistical models. We conclude that factor and bridge models are among the best individually performing models in the suite. Forecasting accuracy obtained using disaggregated models of factor and bridge models is …
A novel intrinsically disordered outer membrane lipoprotein ofAggregatibacter actinomycetemcomitansbinds various cytokines and plays a role in biofil…
2017
Intrinsically disordered proteins (IDPs) do not have a well-defined and stable 3-dimensional fold. Some IDPs can function as either transient or permanent binders of other proteins and may interact with an array of ligands by adopting different conformations. A novel outer membrane lipoprotein, bacterial interleukin receptor I (BilRI) of the opportunistic oral pathogen Aggregatibacter actinomycetemcomitans binds a key gatekeeper proinflammatory cytokine interleukin (IL)-1b. Because the amino acid sequence of the novel lipoprotein resembles that of fibrinogen binder A of Haemophilus ducreyi, BilRI could have the potential to bind other proteins, such as host matrix proteins. However, from th…
Oxidative stress, oxidative stress-based diseases and Mediterranean diet. Raman spectroscopy monitoring of skin carotenoids in healthy individuals an…
Abstract Evaluating the level of body antioxidants may reveal a more or less severe oxidative stress condition in either healthy people or subjects with pathologies, and can be suggestive for suitable dietary interventions to possibly affect it. In this work taking advantage from the Raman spectroscopic technology to measure the level of skin carotenoids in a simple and non-invasive manner, healthy people (age 15 to 70, n=155) and women who had surgery for breast cancer (BC) (age 38 to 76, n=71) have been screened to assess to what extent an increased intake of fruit and vegetables (healthy people and patients), associated with diets based on a classical Mediterranean style and that did not…
Ruolo delle politiche urbane contro la segregazione e per il riconoscimento di un plurale diritto alla città
2015
L'articolo affronta il complesso ruolo delle politiche urbane alla luce del profondo cambiamento della società italiana, sempre più segnata da fenomeni di frammentazione e impoverimento. La suddetta analisi è condotta attraverso la lettura delle trasformazioni della dimensione spaziale la cui natura segregativa si riscontra con maggiore frequenza oggi nelle realtà urbane italiane, coinvolgendo vecchi e nuovi abitanti, con plurali articolazioni di popolazioni e spazi e conseguenti disuguaglianze che caratterizzano i primi nella fruizione dei secondi.
Síntesis y caracterización de poliuretanos termoplásticos basados en policarbonato dioles. Relación estructura/propiedades.
2012
Los poliuretanos son una familia de polímeros muy versátil, utilizados en un amplio rango de aplicación, desde las espumas rígidas-flexibles, materiales elastómeros, recubrimientos, adhesivos, hasta materiales con aplicaciones biomédicas. Esta gran versatilidad es debida a que los reactivos utilizados en la síntesis de los poliuretanos son muy variados, permitiendo la gran versatilidad en la formulación del poliuretano y en las propiedades del mismo. Los poliuretanos termoplásticos elastómeros son copolímeros de bloque, que a temperatura ambiente se comportan como elastómeros entrecruzados, y sin embargo a diferencia de los elastómeros convencionales, por acción del calor se pueden conforma…
