Global RDF Vector Space Embeddings

2017

Vector space embeddings have been shown to perform well when using RDF data in data mining and machine learning tasks. Existing approaches, such as RDF2Vec, use local information, i.e., they rely on local sequences generated for nodes in the RDF graph. For word embeddings, global techniques, such as GloVe, have been proposed as an alternative. In this paper, we show how the idea of global embeddings can be transferred to RDF embeddings, and show that the results are competitive with traditional local techniques like RDF2Vec. peerReviewed

Exploring sequential interplay between challenges and regulatory processes in collaborative learning with process mining

2023

This study explored the sequential interplay between challenges and regulatory processes in high- and low-performing collaborative groups. 66 students from a Finnish higher education institution participated in a collaborative task in groups of three. Approximately 34 h of video data were coded. The sequential analysis revealed that both groups had higher sequential transitions between cognitive regulation and emotional/motivational regulation, rather than cognitive challenges. The high-performing groups demonstrated a stronger sequential link between emotional/motivational regulation and cognitive regulation than the low-performing groups did when faced with cognitive challenges. The study…

Urban Heat Island (UHI) and heat waves: what relations?

2018

With four years of measurements and alarge sample of stations, the MUSTARDijon network allows for a detailed characterization of the Urban HeatIsland (UHI), a warm season phenomenon. But UHI and maximum temperature values are out of phase at twodistinct time-scales. Seasonally, the maxima of UHI occur from May to July, i.e. before the annual peak oftemperature (July to August). At a daily time-scale, analysis of the two heat waves of July 2015 shows a lag of afew days between the peak of UHI and the heat wave. Two hypotheses are suggested to explain these lags:changes in radiative conditions and/or energy fluxes between the ground surface and the atmosphere.

Urban Heat Island and air quality, Dijon, winter 2014-2015.

2016

For the 2014-2015 Winter, thetemperature patterns and the Air Quality measured over the Grand Dijon urban area are studied together.Meteorological conditions favoring the development of an Urban Heat Island (UHI) are distinguished fromthose giving rise to pollution episodes. Winter UHI are next characterized, with radiative situations followedafter the sunset by relatively strong UHI (about 3°C), and days with no insolation during which anthropogenicheat is suspected to produce a small UHI (few tenths of °C).

Kalevalan naiset ja tiedon yöpuoli : Lönnrotin jalanjäljissä kohti Kalevalan naisten tarinoita

2017

My dissertation deals with the most important female figures of the Finnish national epic New Kalevala (1849): Aino, Louhi, Lemminkäinen’s mother and Marjatta. The epic was compiled by Elias Lönnrot (1802–1884) from Karelian and Finnish oral folklore. My reading leans on the intuitive night side of knowledge, which Lönnrot (1832) introduced as a counterpart to the day side of rational knowledge. To illustrate the logic of the night side of knowledge, I analyse Lönnrot as both a collector of oral folklore and a compiler of a work of epic poetry. I propose that Lönnrot’s choice of presenting the Kalevala as an epic – a total work of art – provided the stories of its female characters with the…

Preconditioning of the generalist herbivore Trialeurodes vaporariorum to greenhouse monocultures and its subsequent performance on wild polycultures

2016

Generalist herbivores can face many challenges when choosing their host plant. This can be particularly difficult if their choice and performance are affected by host experience. Greenhouse whitefly, Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae), is an invasive generalist herbivore, which has established in year-round greenhouses at northern latitudes where it cannot overwinter outdoors. It mainly uses crops such as cucumber (Cucumis sativus L.), tomato (Solanum lycopersicum L.), and ornamentals as host plants. However, every summer the insect escapes greenhouses and is exposed to natural vegetation. We evaluated the performance of T. vaporariorum on diverse vegetation outside…
