Identifying relevant segments of AI applications adopters : Expanding the UTAUT2’s variables
2021
Artificial intelligence (AI) is a future-defining technology, and AI applications are becoming mainstream in the developed world. Many consumers are adopting and using AI-based apps, devices, and services in their everyday lives. However, research examining consumer behavior in using AI apps is scant. We examine critical factors in AI app adoption by extending and validating a well-established unified theory of adoption and use of technology, UTAUT2. We also explore the possibility of unobserved heterogeneity in consumers’ behavior, including potentially relevant segments of AI app adopters. To augment the knowledge of end users’ engagement and relevant segments, we have added two new antec…
Subsidizing private childcare in a universal regime
2023
AbstractAll families in Finland have the freedom to choose between subsidized home care, universal public childcare, and private childcare. We study the impact of the introduction of private childcare subsidies in Finland. Private childcare subsidies have causal effects on take-up but no impact on home care or employment among women with small children. Instead, private services seem to crowd out public childcare. Private services have a socioeconomic gradient by mother’s education that steepens when the subsidy increases. Families’ preferences between home care, public childcare, and private childcare do not explain the result.
Heterogeneity of traditional and digital media use among older adults : A six-country comparison
2021
The concept of aged heterogeneity has been associated with older adults' ability to adapt to the digital age without a systematic empirical analysis. We analyse retired adults' (aged 62 or more) use of traditional media and their digital equivalents in six countries. First, we ask whether heterogeneity in traditional and digital media use increases with age. Second, we study to what extent gender is related to this heterogeneity, and third, the country differences in the heterogeneity of media use in later life. We analyse the 2018 data (N = 5865) of the ‘Older audiences in the digital media environment’ survey using zero-inflated negative binomial models. The results provide partial suppor…
Characterization of spatial porosity and mineral distribution of crystalline rock using X-ray micro computed tomography, C-14-PMMA autoradiography an…
2019
The spatial porosity and mineral distribution of geological materials strongly affects transport processes in them. X-ray micro computed tomography (X-mu CT) has proven to be a powerful tool for characterizing the spatial mineral distribution of geological samples in 3-D. However, limitations in resolution prevent an accurate characterization of pore space especially for tight crystalline rock samples and 2-D methods such as C-14-polymethylmethacrylate (C-14-PMMA) autoradiography and scanning electron microscopy (SEM) are needed. The spatial porosity and mineral distributions of tight crystalline rock samples from Aspo, Sweden, and Olkiluoto, Finland, were studied here. The X-mu CT were use…

Opetusmenetelmät heterogeenisen ryhmän liikuntataitojen harjoittelussa
2015
Tutkimuksen päätarkoituksena oli löytää heterogeenisille liikuntaryhmille sopivia opetusmenetelmiä. Tarkastelun kohteena oli liikuntataitoharjoittelu motorisesti taitavan ja taidoiltaan heikon oppilaan näkökulmista. Tutkimuksen kohderyhmän ikävariaatio oli suuri sisältäen esikouluryhmän ja perusopetuksen kolmannen sekä seitsemännen luokan liikuntaryhmän. Ryhmät olivat liikuntataitojen osalta heterogeenisia. Tutkimus toteutettiin sekä laadullisena että määrällisenä tapaustutkimuksena. Eritasoisten oppilaiden taitoharjoitteluun osallistumista tarkkailtiin harkinnanvaraisesti valittua videoaineistoa systemaattisesti observoimalla. Materiaali käsitti kuusi liikuntatuntia. Tutkimusta varten oli …

Oppilasryhmän vaikutus opettajan toimintaan yläkoulun poikien palloilutunneilla
2016
Tutkimuksemme tarkoituksena oli selvittää, miten erilaiset oppilasryhmät vaikuttavat opettajan toimintaan ja eroaako opettajan toiminta hetero- ja homogeenisen ryhmän välillä. Tutkimme opettajan toimintaa kolmen pääkohdan pohjalta, joita olivat organisointi, instruktio, vuorovaikutus. Tämän lisäksi teimme havaintoja tunnin yleisilmeestä. Aineistona tutkimuksessa käytettiin kahdeksaa videoitua liikuntatuntia, jotka olivat yläkoulun poikien palloilutunteja. Yksi opettaja piti saman aiheen tunnin kahdelle erityyppiselle ryhmälle, joista toinen oli taidoiltaan heterogeeninen ja toinen homogeeninen. Tarkastelimme videoilta opettajan käyttämiä opetusmenetelmiä, sekä tunnin aloitus- ja lopetushetk…

DIALECTIC AND SOCIAL HETEROGENEITY IN ERNESTO LACLAU
2020
The present article aims to examine critically Laclau’s claim that the trend toward social heterogenization revokes the Dialectic, or, more specifically, the clear and strict line of demarcation between what falls within the Dialectic and what falls outside of it. Polemicizing with the assumption of this reading, I argue that the appearance of a radical heterogeneity rather exposes the undecidability of relations between the Dialectic and what is a heterogeneity. To undergo the experience of this relation means not only to confront something that dislocates the Dialectic, but also what makes it what it is. The concrete determination of this limit relation is precisely what is at stake in th…
