   Författare :Ulrika B. Andersson; Stefan Gustafson; Håkan Löfgren; Linda Fälth; Gunilla Sandberg; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Early reading instruction; Decoding; Forward-looking assessment; Assessment aspects; Response to intervention RTI ; Formative assessment; Teacher s professionalism; Tidig läsundervisning; Avkodning; Framåtsyftande bedömning; Bedömningsaspekter; Response to Intervention RTI ; Formativ bedömning; Lärares professionalism;

   Sammanfattning : Syfte är att bidra med kunskap om hur framåtsyftande bedömning kan användas och används av lärare som underlag för pedagogiska åtgärder i tidig läsundervisning. I avhandlingen har jag ett pragmatiskt förhållningssätt till både teorier och metoder. Avhandlingen bygger på fyra artiklar. LÄS MER

4. 3. Local Conditions for Long Cycles in Graphs

   Författare :Jonas B. Granholm; Carl Johan Casselgren; Armen Asratian; Jørgen Bang-Jensen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : A Hamilton cycle in a graph is a cycle that passes through every vertex of the graph. A graph is called Hamiltonian if it contains such a cycle. The problem of determining if a graph is Hamiltonian has been studied extensively, and there are many known sufficient conditions both for Hamiltonicity and for other, related properties. LÄS MER

5. 4. Quality in Learning in Rwandan Higher Education : Different stakeholders’ perceptions of students’ learning and employability

   Författare :Penelope B. Mbabazi; Andreas Fejes; Sofia Nyström; Lars-Owe Dahlgren; Martin Stigmar; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Students’ learning; employability; higher education; Rwanda; Studenters lärande; anställningsbarhet; högre utbildning; Rwanda;

   Sammanfattning : The aim of the thesis is to investigate quality in learning in higher education in Rwanda by focusing on students’ learning and their employability. This focus allows for an understanding of key challenges for Rwandan higher education to emerge, at a time when more and more students are enrolling. LÄS MER

7. 5. Engineered ion-bombardment as a tool in thin film deposition

   Författare :Rommel Paulo B. Viloan; Ulf Helmersson; Daniel Lundin; Rainer Hippler; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HiPIMS; Bipolar HiPIMS; Ion-bombardment; Thin film;

   Sammanfattning : Energetic-ion bombardment has become an attractive route to modify the crystal growth and deposit high quality thin films. In high-power impulse magnetron sputtering (HiPIMS) where the discharge is characterized by a significant amount of ions of the sputter-ejected atoms, energetic-ion bombardment effects could not be underestimated.
