  1. 1. Everyday life, crime, and fear of crime among adolescents and young adults

    Författare :Alexander Engström; Marie Torstensson Levander; Anna-Karin Ivert; Micael Björk; Anna Dåderman; Vania Ceccato; Malmö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adolescents; crime; fear of crime; lifestyle-exposure theory; offending; routine activity theory; smartphone; victimisation; youth; young adults; Kriminologi; Criminology;

    Sammanfattning : Drawing on lifestyle-routine activity theory, this dissertation explores associations between everyday life, crime, and fear of crime among adolescents and young adults. It also examines the operationalisation of the concepts of lifestyle and routine activities, and explores the use of experience methods, via a smartphone application named STUNDA, to collect data about everyday life.

  3. 2. Algorithmic Methods in Combinatorial Algebra

    Författare :Anna Torstensson; Algebra; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; algebraic geometry; field theory; Number Theory; maximal symmetry group; resultant; SAGBI basis; Orthogonal decomposition; algebra; group theory; Talteori; fältteori; algebraisk geometri; gruppteori;

    Sammanfattning : This thesis consists of a collection of articles all using and/or developing algorithmic methods for the investigation of different algebraic structures. Part A concerns orthogonal decompositions of simple Lie algebras. The main result of this part is that the symplectic Lie algebra C3 has no orthogonal decomposition of so called monomial type.

  4. 3. Situational sources of rule-breaking acts : an analytic criminology approach

    Författare :Alberto P. Chrysoulakis; Marie Torstensson Levander; Anna-Karin Ivert; Alfonso Serrano Maíllo; Malmö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adolescents; collective efficacy; crime propensity; delinquency; mechanisms; morality; peers; rule-breaking; self-control; situational action theory; time-use; unstructured socialising; Kriminologi; Criminology;

    Sammanfattning : Criminology has long been divided by mainly focusing on people’s propensities to commit crimes, on the one hand, and environmental characteristics conducive to crime, on the other. Such a division must be bridged to advance knowledge about why some people, but not others, commit rule-breaking acts in some environments but not in others. LÄS MER

  5. 4. Locating place, crime and the fear of crime : methodological and theoretical considerations

    Författare :Karl Kronkvist; Robert Svensson; Anna-Karin Ivert; Marie Torstensson Levander; Lieven Pauwels; Reka Solymosi; Malmö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Crime; criminology of place; fear of crime; micro-place; smartphone; unsafe locations; Kriminologi; Criminology;

    Sammanfattning : Much previous research on the fear of crime has focused on why some individuals, with certain characteristics, experience more or less fear of crime than others. However, there is also a growing body of research examining the role that the neighbourhood context in which individuals reside plays in shaping such feelings and perceptions. LÄS MER
