  1. 11. Linking Programming to Representations : Understanding meaning-making in physics education through semiotic resources

    Författare :Kim Svensson; Nationellt Resurscentrum för Fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social Semiotics; Programming; Transduction; Semiotic Resources; Representations; Transductive Link; Fysicumarkivet A:2022:Svensson; Social Semiotik; Programmering; Transduction; Semiotisk Resurs; Representationer; Transductiv Länk;

    Sammanfattning : Programming is investigated with a social semiotic lens to study how programming can contribute to meaning-making in physics. The analysis focuses on how new and dynamic representations can be created with the help of programming and how programming allows students to investigate and create their own models of physical phenomena.

  3. 12. Integral representations of Herglotz-Nevanlinna functions

    Författare :Mitja Nedic; Annemarie Luger; Alexandru Aleman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integral representations; Herglotz-Nevanlinna functions; several complex variables; Mathematics; matematik;

    Sammanfattning : In this thesis, we study integral representations of Herglotz-Nevanlinna functions, that is to say holomorphic functions defined on a product of several copies of the complex upper half-plane having non-negative imaginary part. The manuscript is divided into three parts, beginning with a general introduction followed by two papers. LÄS MER

  4. 13. Ageism in the Media : Online Representations of Older People

    Författare :Wenqian Xu; Annika Taghizadeh Larsson; Lars-Christer Hydén; Andreas Motel; Alexander Peine; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ageism; Power relations; Representations of older people; Third age; Social media logic; Ålderism; Maktrelationer; Representationer av äldre; Tredje åldern; Social medialogik;

    Sammanfattning : Ageism is a social problem that has harmful effects on the wellbeing of older people and needs to be tackled. It is pervasive and evident in the media (e.g., films, television, print and social media). LÄS MER

  5. 14. Students’ meaning-making of epigenetic visual representations : An exploration within and between levels of biological organization

    Författare :Annika Thyberg; Konrad Schönborn; Niklas Gericke; Clas Olander; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biological organization levels; Genetics education; Learning progression; Meaning-making of epigenetics; Secondary school; Visual representations; Yo-yo reasoning; Biology; Biologi;

    Sammanfattning : This thesis explores lower secondary students’ meaning-making of epigenetic visual representations within and between biological organization levels. Data obtained from five focus group discussions where students indicated and reasoned about eight epigenetic visual representations were explored. LÄS MER

  7. 15. Semigroups, multisemigroups and representations

    Författare :Love Forsberg; Volodymyr Mazorchuk; Ernst Dieterich; Stuart Margolis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; representation theory; semigroups; multisemigroups; category theory; 2-categories;

    Sammanfattning : This thesis consists of four papers about the intersection between semigroup theory, category theory and representation theory. We say that a representation of a semigroup by a matrix semigroup is effective if it is injective and define the effective dimension of a semigroup S as the minimal n such that S has an effective representation by square matrices of size n.
