Svensklärares uppfattningar om handledning i gymnasiet
2018
Tutkimukseni tarkoituksena oli selvittää, millaisia käsityksiä lukion ruotsin kielen opettajilla on ohjauksesta. Tutkimuksessa käytettiin fenomenografista menetelmää, joka keskittyy käsitysten tutkimiseen aineistolähtöisesti. Aineisto kerättiin haastattelemalla kahdeksaa opettajaa neljästä eri lukiosta ja se analysoitiin fenomenografisen analyysimallin mukaisesti keskittyen aineistosta nousevien käsitysten moninaisuuteen haastateltavien yksilöllisten erojen ja yhtäläisyyksien sijasta. Käsityksistä muodostettiin kaksitasoinen kategoriajärjestelmä, joka koostuu viidestä kuvauskategoriasta; 1) Ohjauksen tarkoitus, 2) Edellytykset hyvälle ohjaukselle, 3) Ohjausvastuun jakautuminen lukiossa, 4) …
"Yhdessä toisten kanssa tehdessä oppii paitsi ruotsia, myös sosiaalisia taitoja ja yhdessä tekeminen tekee oppimisesta hauskaa." : gymnasisters åsikt…
2013
Tämän kvantitatiivisen tutkielman tarkoituksena on selvittää lukiolaisten suhtautumista ryhmätyöskentelyyn ruotsin kielen kursseilla. Lisäksi tutkimuksessa tarkasteltiin, mitkä asiat tekevät lukiolaisten mielestä ryhmätyöstä onnistuneen ja vastaavasti epäonnistuneen. Kolmantena tutkimuskysymyksenä tutkittiin, miten he suhtautuvat tiettyihin keskeisiin periaatteisiin ryhmätyöskentelyssä eli ryhmän heterogeeniseen koostumukseen, positiiviseen keskinäiseen riippuvuuteen, vuorovaikutukseen, yksilölliseen vastuuseen, sosiaalisiin taitoihin ja arviointiin. Tutkimusaineisto kerättiin käyttämällä elektronista kyselylomaketta. Tutkimukseen osallistui 99 informanttia kolmesta lukiosta Keski-Suomen ja…

On the Ability of Perfluorohexane Sulfonate (PFHxS) Bioaccumulation by Two
2019
PFASs (perfluoroalkyl and polyfluoroalkyl substances) are highly fluorinated, aliphatic, synthetic compounds with high thermal and chemical stability as well as unique amphiphilic properties which make them ingredients in a range of industrial processes. PFASs have attracted consideration due to their persistence, toxicity and bioaccumulation tendency in the environment. Recently, attention has begun to be addressed to shorter-chain PFASs, such as perfluorohexane sulfonate [PFHxS], apparently less toxic to and more easily eliminated from lab animals. However, short-chain PFASs represent end-products from the transformation of fluorotelomers whose biotic breakdown reactions have not been ide…
Cyberbullying and traditional bullying among Nordic adolescents and their impact on life satisfaction.
2019
Aims: The aim of this study was to investigate the prevalence of cybervictimization in the six Nordic countries and to assess its overlap with traditional bullying. A further aim was to examine potential associations between life satisfaction, on the one hand, and traditional bullying and cyberbullying on the other. Methods: Analyses were based on data from the 2013⁄2014 Health Behaviour in School-aged Children study. It included 32,210 boys and girls, aged 11, 13, and 15, living in the six Nordic countries. Results: The prevalence of cyberbullying by both pictures and by messages was around 2% in all the Nordic countries except Greenland. There it was considerably higher. The prevalence o…
Women's Emotions Towards the Mobile Phone
2012
The purpose of this study is to investigate whether women's emotions associate differently with the mobile phone depending on the type of family in which they live. James A. Russell's circumplex model of affect which explores four main emotional dimensions, excitement, distress, depression and contentment, was applied. The article is based on the female sub-sample (N = 3,704) of nationally representative survey data collected from Italy, France, the UK, Germany and Spain (N = 7,255) in 2009. The results show that it is women living in blended families who seem to associate more distress and less feelings of contentment with the mobile phone than women living in other types of family. peerRe…
Predominio de las cheapfakes en redes sociales. Complejidad técnica y funciones textuales de la desinformación desmentida en Argentina durante 2020
2022
Research on disinformation concentrates a growing interest in the design of deepfakes and the possible political, economic and social implications of their viral dissemination on social networks. However, as much or more worrying are the cheapfakes: the hoaxes created by the users themselves through the native features of their mobile devices, the rude manipulation of pre-existing files or the simple addition of text that alters the original meaning of the shared messages. The objective of this research is to analyze the degree of technological complexity of the disinformation that circulated in Argentina during 2020 throughout social networks, as well as the role that the text played in it…
Deconstructing Stereotypes Through Reading Children’s Literature as Intergenerational Play: The Case of the Stepmother
2021
One of the key roles within stepfamilies, the role of stepmother has been and still is stigmatized with an aura of wickedness, produced by folk and fairy tales as well as by the media. As a review of theoretical frameworks of children’s literature indicates, there is a shortage of methodological proposals for handling such controversial topics in literary education. Thus, the objective of this chapter is to present and test a methodology for analyzing the capacity of children’s literature to shape social understanding of such intergenerational topics. This study was based on the exploration of the picture book by Gonzalez and Alberdi entitled La novia de papa tambien me quiere (My Dad’s Gir…

Solution of universal nonrelativistic nuclear DFT equations in the Cartesian deformed harmonic-oscillator basis. (IX) HFODD (v3.06h) : a new version …
2021
We describe the new version (v3.06h) of the code HFODD that solves the universal nonrelativistic nuclear DFT Hartree-Fock or Hartree-Fock-Bogolyubov problem by using the Cartesian deformed harmonic-oscillator basis. In the new version, we implemented the following new features: (i) zero-range three- and four-body central terms, (ii) zero-range three-body gradient terms, (iii) zero-range tensor terms, (iv) zero-range isospin-breaking terms, (v) finite-range higher-order regularized terms, (vi) finite-range separable terms, (vii) zero-range two-body pairing terms, (viii) multi-quasiparticle blocking, (ix) Pfaffian overlaps, (x) particle-number and parity symmetry restoration, (xi) axializatio…
