  1. 1. Modelling and Inference for Spatio-Temporal Marked Point Processes

    Författare :Ottmar Cronie; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Asymptotic normality; Consistency; Cox-Ingersoll-Ross process; Diffusion process; Edge correction; Goodness-of-fit; Richards growth function; Growth-interaction process; Immigration-death process; Least squares estimation; Markov process; Maximum likelihood estimation; Open-growth; Spatio-temporal marked point process; Stationarity; Stochastic differential equation; Transition density; Asymptotic normality;

    Sammanfattning : This thesis deals with inference problems related to the growth-interaction process (GI-process). The GI-process is a continuous time spatio-temporal point process with dynamic interacting marks (closed disks), in which the immigration-death process (ID-process) controls the arrivals of new marked points as well as their potential life-times.

  3. 2. Different Aspects of Inference for Spatio-Temporal Point Processes

    Författare :Ottmar Cronie; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Asymptotic normality; Consistency; Edge correction; Immigration-death process; Least squares estimation; Maximum likelihood estimation; Spatio-temporal marked point process; Transition probability.; Consistency;

    Sammanfattning : This thesis deals with inference problems related to the Renshaw-Särkkä growth interaction model (RS-model). It is a continuous time spatio-temporal point process with time dependent interacting marks, in which the immigrationdeath process (a continuous time Markov chain) controls the arrivals of new marked points as well as their potential life-times.

  4. 3. Elevers interaktiva lärande vid problemlösning i grupp : En processtudie

    Författare :Anders Jakobsson; Pedagogik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social constructivistic theory; science; problem solving in groups; learning attitudes; greenhouse effect; cognitive and knowledge development; collaboration; socio-cultural theory.; Pedagogy and didactics; Pedagogik; didaktik; pedagogisk metodik;

    Sammanfattning : This study gives an account of a teaching situation in the eighth grade with 20 student's aged 14-15. The students have worked with a scientific problem focussed on the greenhouse effect and the earth's global warming, based on a problem solving and information seeking way of working in groups.

  5. 4. ”Mellanklass kan man kalla det” : Om tid och meningsskapande vid övergången från förskoleklass till årskurs ett

    Författare :Lina Lago; Anna-Liisa Närvänen; Karin Osvaldsson Cromdal; Ann Quennerstedt; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; School transitions; preschool class; school; childhood; time; temporality; socialization; rites of passage; priming events; educational practice; Skolövergångar; förskoleklass; skola; skolstart; barndom; tid; temporalitet; socialisation; passageriter; nyckelhändelser; pedagogiskt arbete;

    Sammanfattning : Avhandlingens syfte är att undersöka övergången från förskoleklass till årskurs ett och hur barn lär känna och skapar mening om vad skola och förskoleklass är. Detta görs genom att studera hur övergången från förskoleklass till årskurs ett markeras genom olika aktiviteter och de processer i vilka barn tillsammans med andra barn, lärare och kontext skapar mening kring övergången.

  7. 5. Dating for innovation : recognizing and creating opportunities in fluid environments through collaborative interorganizational relationships

    Författare :Cassandra Marshall; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Both practice and theory present good reason to believe that collaborative interorganizational relationships have become particularly important for innovation and new product development in industries characterized by rapid technological change and dynamic competition. Even though collaboration across organizational boundaries represents an important change in the way companies innovate and develop new products (services and processes), it appears as if the process and practical steps of such arrangements are scantly explored.
