  1. 1. Interaction Between Drosophila melanogaster mbn-2 Cells and Bacteria

    Författare :Karin Johansson; Kenneth Söderhäll; Lage Cerenius; Martin Bilej; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Drosophila; innate immunity; bacteria; host - pathogen interaction; Cellbiologi; Cell biology; Cellbiologi;

    Sammanfattning : Innate immunity relies on a repertoire of germline-encoded non-rearranging pattern recognition receptors that bind to invariant microbial surface molecules. This event initiates a number of signal transduction cascades that lead to humoral and cellular defense responses like synthesis of antimicrobial peptides, phagocytosis and coagulation – mechanisms that efficiently fight infectious microorganisms and have been evolutionary conserved to exist in parallel with the antibody-based adaptive immunity found in vertebrates.

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; History teaching; historical learning; history education; intercultural competence; intercultural education; upper secondary school; object of learning; historical narrative; historieundervisning; interkulturell kompetens; historiskt lärande; interkulturell utbildning; historiemedvetande; gymnasiet; klassrumsstudie; lärandeobjekt; lärandemål; historisk berättelse; narrativ; Pedagogiskt arbete; Educational Work;

    Sammanfattning : Abstract Title: History teaching and intercultural competence This study takes as its starting point the relationship between the multicultural and globalised society and history as a school subject, and explores it theoretically as well as empirically.  Intercultural historical competence, which is the main theoretical and analytical concept of the study, is developed from theories of narrative competence and theories of intercultural competence, and is positioned in the intersection between the two.

  4. 3. Interkulturalitet och historia : Historieundervisningens teori och praktik i en mångkulturell värld

    Författare :Maria Johansson; Kenneth Nordgren; Martin Stolare; Henrik Åström Elmersjö; Karlstads universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; history education; intercultural competence; multicultural education; historical consciousness; classroom studies; case study; historial inquiry; didactic model; historieundervisning; interkulturell kompetens; mångkulturalitet; historiemedvetande; klassrumsstudier; fallstudie; frågedriven undervisning; didaktisk modell; History; Historia;

    Sammanfattning : The purpose of this thesis is to investigate interculturality in history as an idea and practice. Two overarching research questions are raised, each concerning the theoretical and practical levels: How can history, as a field of knowledge and teaching, be related to intercultural learning as a normative practice? What obstacles and opportunities for teaching and learning emerge when intercultural historical learning is the goal? This thesis comprises four published studies. LÄS MER

  5. 4. Lära historia genom källor : Undervisning och lärande av historisk källtolkning i grundskolan och gymnasieskolan

    Författare :Patrik Johansson; Kenneth Nordgren; Kristina Lanå; Ingmarie Danielsson Malmros; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; history teaching; historical enquiry; primary source analysis; source criticism; source interpretation; interpretation of historical sources; historical consciousness; intercultural historical learning; learning study; phenomenography; de estetiska; humanistiska och samhällsvetenskapliga ämnenas didaktik; Arts; Humanities and Social Science Education;

    Sammanfattning : This doctoral thesis is concerned with how students learn historical source interpretation and the design of facilitating teaching practices. Source interpretation is at the core of historians’ professional practice and, while being a key aspect of historical learning, it is sometimes misunderstood or misrepresented in history teaching.

  7. 5. Regulation of hematopoiesis in the freshwater crayfish, Pacifastacus leniusculus : role of transglutaminase

    Författare :Kingkamon Junkunlo; Irene Söderhäll; Kenneth Söderhäll; Chadanat Noonin; Mats W Johansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ast1; clotting protein; crayfish; hematopoiesis; PVF PVR; ROS; transglutaminase; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Sammanfattning : The freshwater crayfish, Pacifastacus leniusculus, has been used as a model for studying hematopoiesis or blood cell production or hematopoiesis and immunity. The work of this thesis aims to investigate the impact of factors such as ROS signaling, Ast1, and the PVF/PVR signaling pathway in controlling stem cell behavior during hematopoiesis and specifically the role of the crosslinking enzyme transglutaminase (TGase) in regulation of hematopoiesis.
