In Situ TEM Study of the Amorphous-to-Crystalline Transition during Dielectric Breakdown in TiO Film.

Dielectric breakdown of oxides is a main limiting factor for improvement of the performance of electronic devices. Present understanding suggests that defects produced by intense voltage accumulate in the oxide to form a percolation path connecting the two electrodes and trigger the dielectric breakdown. However, reports on directly visualizing the process at nanoscale are very limited.

Development of a tool to assess beliefs about mythical causes of cancer: the Cancer Awareness Measure Mythical Causes Scale.

Objectives: We aimed to develop a reliable and valid measure to assess public beliefs in mythical causes of cancer: the Cancer Awareness Measure-MYthical Causes Scale (CAM-MYCS).

Design And Setting: Cancer myth items were generated from a literature review, social media and interviews (n=16). The CAM-MYCS was prepared by reducing items using (a) an online sample (n=527) with exploratory factor analysis and (b) cancer experts with Delhpi methodology (n=13).

Young people's beliefs about the risk of bowel cancer and its link with physical activity.

Objectives: The primary objective was to explore young people's risk appraisals of bowel cancer, including whether they had a coherent understanding of the protective effects of physical activity (PA). A secondary objective was to examine whether the illness risk representations (IRRs) framework could be used to understand beliefs underlying bowel cancer risk appraisals.

Design: Qualitative.
