Lithium indium diselenide (LISe) is a semiconductor that holds promise for neutron imaging sensor technologies because of its high neutron absorption efficiency and its corresponding ability to discriminate between gamma rays and neutrons. However, being a semiconductor, LISe may not be sufficiently radiation hard for practical application in radiation hard environments. Therefore, a systematic evaluation of the changes in material and electronic properties of LISe after high neutron fluence exposures is investigated. Herein, the characterization methods are utilized which included UV–vis, X‐ray diffraction, radioluminescence, Raman, fourier transform infrared spectroscopy (FTIR), current–voltage, and neutron sensing. Characteristics of LISe material that appeared in the literature are identified herein along with several that are expected to appear based on theoretical analyses. The results obtained show clear changes in the material properties of LISe after neutron exposure up to a fluence of 1016 n cm−2. However, LISe is still able to sense neutrons above the background at 1016 n cm−2, suggesting that LISe may be suitable for use in neutron imaging sensors at neutron imaging facilities.

<p>Research has shown that when people see young survivors of stroke, they often misattribute the person’s symptoms to other factors (Wainwright et al., 2013). Consequently, these stroke survivors may suffer feelings of resentment towards, and from their acquaintances. They may also struggle to obtain or retain a job. This thesis examines whether these misattributions for stroke survivors’ symptoms are affected by the information people have about the stroke survivor and the rapidity of the change in their behaviours. Experiment 1 investigated if the stroke survivor’s age (72, 32 or unstated) and the level of information (no information, implied stroke or explicit stroke) for their behaviours influenced people’s attributions. Experiment 1 showed that people attributed the behavioural changes to factors other than stroke when no additional information is present, and they attributed the behaviours to stroke when stroke was explicitly described. When stroke was implied, participants rated stroke as the best explanation but only when the target person was 72. Experiment 2 manipulated the rapidity of the stroke survivor’s behavioural changes to assess the effect on attributions. Experiment 2 showed that people attributed the behaviours to stroke more if only one week had passed, and if the target person was 72, but not when he was 32. It was concluded that young stroke survivors may need to disclose their stroke in order for others to correctly attribute their behaviours, as this could improve their rehabilitation.</p>
