Exploring fear of crime : A quantitative study of differential experiences among minority and majority bias-crime victims

Schmidt-Kallesøe, Sofia F. M. January 2023 (has links)
This thesis addresses a significant knowledge gap in the existing literature on bias-crime, which primarily focuses on minorities while neglecting the experiences of majorities. The primary objective of this study is to shed light on bias-crimes targeting majorities and compare their impact on fear of crime with those experienced by minorities. By analysing data from a sample of 1,616 victims, this research reveals that both minority and majority bias-crime victims exhibit similar patterns in terms of fear of crime. Notably, both groups experience heightened levels of fear compared to victims of non-bias crimes, with no significant difference observed between the two. Moreover, this study identifies several factors associated with fear of crime in both minority and majority victims, including recent victimisation, intersectionality, indirect victimisation, and the presence of visibility/visual identifiers. Although this thesis initially aimed to identify differences between the two groups, it ultimately found striking similarities. The discussion section critically examines the potential role of methodological limitations in shaping these findings and offers insights into their implications. By addressing this research gap, this thesis contributes to the criminological field by offering a more comprehensive understanding of bias-crime and its impact on fear of crime among both minority and majority populations.

Nonlinear Analysis of Conventional and Microstructure Dependent Functionally Graded Beams under Thermo-mechanical Loads

Arbind, Archana 2012 August 1900 (has links)
Nonlinear finite element models of functionally graded beams with power-law variation of material, accounting for the von-Karman geometric nonlinearity and temperature dependent material properties as well as microstructure dependent length scale have been developed using the Euler-Bernoulli as well as the first-order and third- order beam theories. To capture the size effect, a modified couple stress theory with one length scale parameter is used. Such theories play crucial role in predicting accurate deflections of micro- and nano-beam structures. A general third order beam theory for microstructure dependent beam has been developed for functionally graded beams for the first time using a modified couple stress theory with the von Karman nonlinear strain. Finite element models of the three beam theories have been developed. The thermo-mechanical coupling as well as the bending-stretching coupling play significant role in the deflection response. Numerical results are presented to show the effect of nonlinearity, power-law index, microstructural length scale, and boundary conditions on the bending response of beams under thermo-mechanical loads. In general, the effect of microstructural parameter is to stiffen the beam, while shear deformation has the effect of modeling more realistically as a flexible beam.
