Estimating aggregated nutrient fluxes in four Finnish rivers via Gaussian state space models
2013
Reliable estimates of the nutrient fluxes carried by rivers from land-based sources to the sea are needed for efficient abatement of marine eutrophication. Although nutrient concentrations in rivers generally display large temporal variation, sampling and analysis for nutrients, unlike flow measurements, are rarely performed on a daily basis. The infrequent data calls for ways to reliably estimate the nutrient concentrations of the missing days. Here, we use the Gaussian state space models with daily water flow as a predictor variable to predict missing nutrient concentrations for four agriculturally impacted Finnish rivers. Via simulation of Gaussian state space models, we are able to esti…
Periodismo especializado y especialización política
2015
En este artículo se revisa la bibliografía sobre periodismo especializado y se analizan los rasgos normalmente aducidos para identificar la especialización periodística, que apuntan por lo general al contenido de los textos: la especificidad temática, el enfoque en profundidad, la metodología de investigación, el recurso a fuentes expertas, la necesidad de formación complementaria a la pro-piamente periodística, la orientación a audiencias segmentadas, el uso de géneros textuales con-cretos, o la adecuación lingüística. La aplicación de estos mismos factores a la especialización políti-ca pone de manifiesto la necesidad de cuestionar los rasgos aducidos y considerar otros criterios en el co…
Postępy w fotowoltanice w Polsce i na świecie = Progress in photovoltaics in Poland and the world
2015
W artykule przedstawiono postęp w zakresie uzyskiwanych sprawności przez ogniwa i moduły fotowoltaiczne (PV) wykonane z różnych materiałów i za pomocą różnych technologii. Zawarto w nim szczegółowe zestawienia tabelaryczne sprawności oraz ich parametrów technicznych. Zwrócono uwagę na nowe obiecujące technologie, które jeszcze nie mają rekordowych sprawności, ale z uwagi na proces ich wytwarzania rokują nadzieje na uzyskanie bardzo dużych sprawności albo tanich wielkopowierzchniowych modułów do komercyjnego zastosowania. Ponadto, omówiono ekonomiczne skutki wdrożenia nowo zawartych zapisów w uchwalonej w lutym 2015 r. Ustawie o Odnawialnych Źródłach Energii (OZE) dla rozwoju rozproszonych i…
Geriatric Care Resources in an Aging Society of Rual and Urban Areas in Poland – Mapping of Current Situation
2017
Prognozy demograficzne GUS pokazują, że do 2035 r. subpopulacja ludzi mających 65 lat i więcej w Polsce wzrośnie o 62% w porównaniu do 2010 r., natomiast subpopulacja ludzi mających 80 lat i więcej wzrośnie w tym samym okresie aż o 96%. Celem artykułu jest diagnoza wybranych zasobów opieki geriatrycznej w sytuacji postępującego starzenia się społeczeństwa wsi i miast w Polsce. Aby zrealizować cel, przedstawiono prognozy demograficzne dla Polski do 2035 roku z podziałem na poszczególne województwa oraz wieś i miasto, jak również dokonano analizy wybranych zasobów opieki geriatrycznej (łóżek geriatrycznych oraz lekarzy geriatrów) w kontekście starzejącego się społeczeństwa. Uzyskane wyniki ba…

Students' usage patterns of video recorded lectures in an undergraduate mathematics course
2018
International audience; It is customary for some universities to offer recordings of live lectures to students. Whether this improves learning and academic performance is debated in the literature. As with most technology, correct usage can lead to increased academic performance, but there are also usage patterns that can be considered counter productive, especially for learning mathematics. In order to investigate patterns in students' usage of such online recorded live lectures, we analyze log files from a server holding the recordings of an undergraduate mathematics course. This poster presents results from the statistical analysis and discusses some of the usage patterns found in light …
Investigating the Structural Properties of an IT-Enabled Resource
2019
The synergistic combination and integration of information technology (IT) and other complementary organizational resources to form IT-enabled resources, has long been identified as one means through which organizations can derive benefits from IT. However, research shows that the integration required to form IT-enabled resources from which organizations derive benefits, also constrains the renewal and redeployment of the IT-enabled resources to address new strategic imperatives. Thus, there are several calls for further research on how organizations can sustain the derivation of benefits from IT especially in dynamic environments. This study responds to such calls. Specifically, it draws o…
Engineering students' engagement with resources in an online learning environment
2018
International audience; This study explores engineering students' interactions with different resources in an online learning environment. The constituent resources of this environment involve MyMathLab which is an online interactive system for practicing mathematics, the tutorial videos, and the textbook. We conducted a qualitative case study to observe a small group of undergraduate engineering students interacting with the resources in a Calculus course. Employing the documentational approach to didactics, we identified several techniques while participants used resources to practice mathematics in MyMathLab environment. We discuss the pragmatic and epistemic value of the identified tech…
STUDENTS’ PERSPECTIVES ON THE IMPLEMENTATION OF MUSICAL ACTIVITIES IN PRESCHOOL EDUCATION
2018
Aim. The aim of the study is to find out students’ perspectives on the necessity, readiness and disturbing factors of implementing musical activities in preschool. The theoretical part of the paper describes the particularity of preschool teachers’ work, the children’s interest in musical activities, and the benefits of implementing musical activities in preschool. 
 Method. The empirical study involved 168 students (N=168), of which 132 students (N=132) are already working as preschool teachers in parallel with their study at the university. The study identified three questions: why do preschool teachers use musical activities? What factors prevent a preschool teacher from using music…
