Kirja-arvostelut alustataloudessa – esimerkkinä käyttäjälähtöiset arvostelut Instagramissa
2021
Kulttuurituotteita eivät sosiaalisen median aikakaudella enää arvostele julkisesti vain perinteisen median ammattikriitikot, vaan myös tavalliset ihmiset osallistuvat teosten julkiseen arvottamiseen erilaisilla digitaalisilla alustoilla. Tarkastelemme tässä artikkelissa kirjallisuusarvosteluja osana alustoitunutta kulttuurituotantoa esimerkkinämme käyttäjälähtöiset kirja-arvostelut erityisesti kuvasovellus Instagramissa. Instagramiin on vakiintunut kirjallisuuskeskusteluyhteisö, jota kutsutaan maailmanlaajuisesti nimellä Bookstagram mutta jolla on myös paikallisia tai alueellisia muotoja, kuten suomalainen Kirjagram. Kysymme, miten käyttäjäarvostelijat esiintyvät niissä arvostelulle määrite…
Cross‐national validation of the Social Media Disorder‐scale : Findings from adolescents from 44 countries
2022
Background and aims There is currently no cross-national validation of a scale that measures problematic social media use (SMU). The present study investigated and compared the psychometric properties of the Social Media Disorder (SMD)-scale among young adolescents from different countries. Design Validation study. Setting and participants Data came from 222,532 adolescents from 44 countries participating in the Health Behaviour in School-aged Children (HBSC) survey (2017/2018). The HBSC survey was conducted in the European region and Canada. Participants were on average 13.5 years old (SD = 1.6) and 51.2% were girls. Measurement Problematic SMU was measured using the 9-item SMD-scale with …
Adolescent use of social media and associations with sleep patterns across 18 European and North American countries
2023
Objective Over the past decade, concurrent with increasing social media use (SMU), there has been a shift toward poorer sleep among adolescents in many countries. The purpose of this study was to examine the cross-national associations between adolescent SMU and sleep patterns, by comparing 4 different categories of SMU (nonactive, active, intense, and problematic use). Design, setting, and participants Data were from 86,542 adolescents in 18 European and North American countries that participated in the 2017/18 Health Behaviour in School-aged study. Measurements Mixed-effects linear regression models were used to examine cross-national associations between 4 SMU categories and adolescent s…
International perspectives on social media use among adolescents: Implications for mental and social well-being and substance use
2022
In the present study, we aimed to explore the relationship between intensity of social media use (SMU), problematic SMU and well-being outcomes. Four categories of SMU were developed taking into account both intensity of use and problematic SMU simultaneously: non-active; active; intense; and problematic use. Using these four categories, we assessed associations between SMU and mental and social well-being, and substance use. Data from 190,089 respondents aged 11, 13, and 15 years from 42 countries involved in the Health Behavior in School-aged Children (HBSC) study were analyzed. With a slight cross-national variance, 78% of adolescents in the sample were classified as active or intense us…
Efectos conductuales y neuroquímicos del consumo de éxtasis y cocaína en ratones adolescentes.
2009
La 3,4-metilendioximetanfetamina (MDMA), una sustancia popularmente conocida como éxtasis, es una droga ilícita consumida habitualmente por adolescentes y adultos jóvenes. Además, el policonsumo es una práctica habitual entre los usuarios de la MDMA, siendo la cocaína una de las drogas más frecuentemente asociadas a esta sustancia. El objetivo del presente trabajo fue evaluar los efectos a corto y largo plazo que se producen tras la administración de la MDMA (5, 10, o 20 mg/kg) sola o en combinación con cocaína (25 mg/kg) en ratones adolescentes. En el estudio sobre el efecto agudo, observamos que ambas drogas administradas individual o simultáneamente incrementan la actividad motora. La do…
Poison frog social behaviour under global change: potential impacts and future challenges
2022
AbstractThe current and cascading effects of global change challenges the interactions both between animal individuals (i.e. social and sexual behaviour) and the environment they inhabit. Amphibians are an ecologically diverse class with a wide range of social and sexual behaviours, making them a compelling model to understand the potential adaptations of animals faced with the effects of human-induced rapid environmental changes (HIREC). Poison frogs (Dendrobatoidea) are a particularly interesting system, as they display diverse social behaviours that are shaped by conspecific and environmental interactions, thus offering a tractable system to investigate how closely related species may re…

The role of social media in the rise of right-wing populism in Finland
2021
Right-wing populism is typically entangled with xenophobic nationalism and neo-conservatism, which often usher in racism and misogyny. In this chapter, the authors take Finland as a case study to examine the role of media technology in the rise of right-wing populism. They demonstrate the strengthening of the far-right ideology on and through social media from the beginning of 2010s. It focuses on the mediated construction of two entangled ideologies in the right-wing populist movement racism and misogyny. In early spring 2020, the debate about Turkey opening its EU border to refugees made Jussi Halla-aho eagerly participate in this discussion in the parliament and on Twitter now as the cha…
Työn hallintamahdollisuuksien ja sosiaalisen tuen suorat ja puskuroivat yhteydet työntekijän koettuun hyvinvointiin : Karasekin mallin tarkastelua su…
2014
Tutkielmassani tarkasteltiin työn hallintamahdollisuuksien ja sosiaalisen tuen suoria sekä puskuroivia yhteyksiä työntekijän koettuun hyvinvointiin, kun hyvinvoinnin mittareina olivat psyykkinen sekä somaattinen oireilu. Tutkielmassani haluttiin myös selvittää, onko sukupuolella merkitystä sille, miten työn hallintamahdollisuudet ja sosiaalinen tuki ovat yhteydessä työntekijän koettuun hyvinvointiin (sukupuoli yhteyksiä muuntavana tekijänä). Tutkielman teoreettisena näkökulmana oli Robert Kara-sekin työn vaatimusten, työn hallinnan sekä sosiaalisen tuen malli eli ns. JDCS-malli. Tämän tutki-muksen aineisto kerättiin elektronisella kyselylomakkeella vuonna 2008 Suomen Akatemian rahoitta-mass…
Conformality and $Q$-harmonicity in sub-Riemannian manifolds
2016
We prove the equivalence of several natural notions of conformal maps between sub-Riemannian manifolds. Our main contribution is in the setting of those manifolds that support a suitable regularity theory for subelliptic $p$-Laplacian operators. For such manifolds we prove a Liouville-type theorem, i.e., 1-quasiconformal maps are smooth. In particular, we prove that contact manifolds support the suitable regularity. The main new technical tools are a sub-Riemannian version of p-harmonic coordinates and a technique of propagation of regularity from horizontal layers.
