A COVID-19 news coverage mood map of Europe
2021
We present a COVID-19 news dashboard which visualizes sentiment in pandemic news coverage in different languages across Europe. The dashboard shows analyses for positive/neutral/negative sentiment and moral sentiment for news articles across countries and languages. First we extract news articles from news-crawl. Then we use a pre-trained multilingual BERT model for sentiment analysis of news article headlines and a dictionary and word vectors -based method for moral sentiment analysis of news articles. The resulting dashboard gives a unified overview of news events on COVID-19 news overall sentiment, and the region and language of publication from the period starting from the beginning of …
Vaaliennusteiden laadinta perustuen Twitter-palvelusta louhittuun dataan
2017
Tässä tutkielmassa käsitellään Twitter-palvelusta louhitun datan hyödyntämistä vaaliennusteiden laadinnan työkaluna. Tutkielmassa esitellään ja analysoidaan tutkimuksia, joissa on louhittu ja pyritty analysoimaan Twitter-palvelun käyttäjien palveluun lähettämiä viestejä. Tutkielman tarkoituksena on kertoa vastaus kysymykseen, voidaanko Twitteristä kerätyn datan pohjalta laatia vaaliennusteita. Aiempia tutkimuksia läpikäymällä esitellään twiittien louhinnan, seulonnan, analyysin ja ennusteiden laadinnan menetelmiä parhaan mahdollisen metodin löytämiseksi. Tässä tutkielmassa vertaillaan louhitun datan pohjalta tehtyjen ennusteiden tuloksia ja luotettavuutta perinteisiin, kyselytutkimuksina to…
Developing response-ability in human-wasp encounters
2023
Learning to live with unloved others is crucial in the ecological crisis. Unloved wasps are feared and disliked for their sting. Understanding of their ecological importance is increasing, however. Human-wasp encounters are changing with environmental changes, and strategies for multispecies cohabitation are needed. This multispecies study highlights features of wasp biology affecting human-wasp encounters and analyzes how conflicted human-wasp relations could be mitigated. The geographical focus is Finland, in the Northern boreal region. Biological analysis specified spatiotemporal aspects affecting human-wasp encounters: human and wasp habitats and preferences overlap ubiquitously. From a…
Rearing background and exposure environment together explain higher survival of aquaculture fish during a bacterial outbreak
2019
1.Parasitic diseases represent one of the greatest challenges for aquaculture worldwide and there is an increasing emphasis on ecological solutions to prevent infections. One proposed solution is enriched rearing, where traditional stimulus‐poor rearing tanks are equipped with different types of structures to increase habitat complexity. Such spatial enrichment is known to increase survival of fish during parasite epidemics, but the underlying mechanisms are still unclear. 2.We studied whether enriched rearing affected infection of an important fish pathogen Flavobacterium columnare in young Atlantic salmon (Salmo salar) and sea‐migrating brown trout (Salmo trutta). First, we used natural b…
