Gamifying Teacher Students’ Learning Platform
2020
This paper presents initial results from a study exploring teacher students’ experiences related to the gamification of an online learning platform in higher education. The aim was to get an understanding of the participants’ views regarding the use of game elements and to examine the user type profile of this group in order to explore the potential of applying user types in planning gamification solutions for teacher students. The participants’ overall experience of having game elements as part of their course platform was principally positive. User types students presented were investigated using the Hexad scale adapted from game design: in this user group, Socialiser and Philanthropist w…
OMAGGIO A DEDALO. Case sognate sul fiume Platani
2019
Il fiume Platani racconta dell’arrivo e della presenza di Dedalo in Sicilia. E poiché il mito non ha tempo si immagina che diversi architetti vadano a trovare Dedalo sulle rive del fiume - dove abita ancora - per chiedergli consigli su certi loro progetti, come una volta gli uomini andavano a Delfi, a Cuma o a Lylibeo per interrogare l’oracolo. I responsi di Dedalo sono famosi progetti di case mai costruite (o scomparse) che bisogna confrontare e fare interferire con i temi moderni dell’abitare e del costruire. «Tra gl’Immortali [direbbe Borges] ogni atto (e ogni pensiero) è l’eco d’altri che nel passato lo precedettero […] o il fedele presagio di altri che nel futuro lo ripeteranno fino al…
Alustan kovuuden vaikutukset juoksun muuttujiin 30 metrillä
2004
Olli Tikkanen. 2004. Alustan kovuuden vaikutukset juoksun muuttujiin 30 metrillä. Liikuntabiologian laitos. Jyväskylän yliopisto. s. 35 Tämän tutkimuksen tarkoituksena oli selvittää juoksualustan kovuuden vaikutuksia juoksunopeuksiin, juoksun muuttujiin sekä juoksijalta vaadittaviin ominaisuuksiin. Koehenkilöinä tutkimuksessa oli 8 nuorta miesurheilijaa, jotka suorittivat 30 metrin nopeustestit kandella erikovuisella alustalla sekä voimatestit. Nopeustesteissä mitattiin juoksuajat 10, 20 ja 30 metriltä sekä kontakti- ja heilandusajat, joiden perusteella laskettlin myös askelpituudet ja —frekvenssit Kaikilla koehenkilöillä, yhtä lukuun ottamatta, juoksuajat olivat huonompia hiekkatekonurmell…
Behaviour-driven development mobiiliohjelmistojen kehityksen tukena
2014
Lähivuosien aikana älypuhelinten yleistyminen on avannut mahdol- lisuuksia aivan uusille ohjelmistomarkkinoille. Samaan aikaan mobiilisovellusten yleistymisen kanssa myös ohjelmistokehityksen menetelmät ovat muuttuneet, ja vanhojen prosessien tilalle on tullut uusia iteratiivisia ketteriä menetelmiä. Tässä tutkielmassa selvitetään mahdollisuuksia hyödyntää käyttäytymislähtöisen ohjelmistokehityksen menetelmiä mobiilisovelluksia kehitettäessä. Since smartphone have become more and more common in recent years, it has opened completely new markets for software developers. At the same time, the software development processes have been evolving from old sequential processes to new agile and iter…
Phytotoxic effects of Lantana camara, Eucalyptus camaldulensis and Eriocephalus africanus essential oils in weeds of Mediterranean summer crops
2009
Abstract The essential oil composition of Lantana camara , Eucalyptus camaldulensis and Eriocephalus africanus was analyzed by means of GC and GC–MS and bioassayed in order to determine their activity against Amaranthus hybridus and Portulaca oleracea . E. camaldulensis essential oil, with spathulenol as the main compound, was the most effective, completely inhibiting germination and seedling growth on both weeds. The essential oil of E. africanus , rich in artemisia ketone, showed activity similar to that of E. camaldulensis on A. hybridus , but it was not so effective against P. oleracea , and L. camara essential oil, with high percentages in sesquiterpene hydrocarbons, also showed higher…
A validated bioenergetics model for ruffeGymnocephalus cernuusand its application to a northern lake
2008
A bioenergetics model was constructed for ruffe Gymnocephalus cernuus, and the model was used to estimate the food consumption of a native G. cernuus stock in Pyhajarvi, a large mesotrophic lake in south-west Finland. The parameters for the bioenergetics model were determined through laboratory experiments conducted at several temperatures between 5 and 22° C for different sized G. cernuus (from 6 to 27 g). The model was verified and validated with independent laboratory growth experiments. The validated model was applied to field data from Pyhajarvi to estimate the food consumption of G. cernuus and its effects on the zoobenthos community during the years 2002–2004. The total annual food c…
Biogeography and ecology of geographically distant populations of sibling Cryptocephalus leaf beetles
2020
Different populations of two closely related species, Cryptocephalusflavipes and C. bameuli, from western (Alps, Apennines and Pyrenees) and central Europe (Poland, Ukraine and Pannonia) were analysed. On the basis of DNA sequences from two genes, cox1 and ef1-alpha, distinctiveness of both species was confirmed. Nevertheless, possible hybrids were identified in Carpathian mountains. We found a significant genetic differentiation among populations of C. flavipes and C. bameuli from distant regions but a high genetic similarity between populations of C. bameuli from north and south of the Carpathians. Demographic estimates suggest a past population expansion in the case of C. bameuli and a r…
Combining stable isotope and intestinal parasite information to evaluate dietary differences between individual ringed seals (Phoca hispida botnica)
2006
The diet and foraging behaviour of nine individual Baltic ringed seals ( Phoca hispida botnica Gmelin, 1785) in the Bothnian Bay were studied by combining results from stable isotope analyses (δ13C and δ15N) with data on intestinal parasites whose occurrence varied among the fish hosts. The patterns of infection with three acanthocephalan parasites, Corynosoma semerme (Forssell, 1904), Corynosoma magdaleni Montreuil, 1958, and Corynosoma strumosum (Rudolphi, 1802), and with a cestode larva, Schistocephalus solidus (Müller, 1776), were examined. The ringed seals become infected with these intestinal parasites by feeding on the fish hosts and hence have different parasite species and differe…
Can large branchiopods shape microcrustacean communities in Mediterranean temporary wetlands?
2011
It was recently suggested that large branchiopods may play a keystone role in temporary aquatic habitats. Using a microcosm experiment manipulating microcrustacean communities of Mediterranean temporary wetlands (Camargue, Southern France), we tested the following hypotheses: (i) large branchiopods (the notostracan Triops cancriformis and the anostracan Chirocephalus diaphanus) can limit microcrustacean densities through both competition and predation; (ii) notostracans create high suspended-matter concentrations through bioturbation, which can negatively impact microcrustaceans; and (iii) the outcome of these biotic interactions is more detrimental at high salinities. We found a strong pr…
Chemical composition of the essential oils fromEriocephalus africanus L. var.africanus populations growing in Spain
2007
Essential oils from the aerial parts of three Eriocephalus africanus L. var. africanus populations were analysed by means of GC–FID and GC–MS. Sixty-one constituents were identified, representing more than 96% of the total oil composition. Artemisia ketone (56.46–56.58%), intermedeol (9.19–11.63%) and γ-eudesmol (4.26–5.64%) were the main compounds. Application of the Pearson correlation coefficient showed high similarity between the nine samples analysed. Copyright © 2007 John Wiley & Sons, Ltd.
