[X-rays in the eye of the general public. A survey of 181 interviews with office personnel (author's transl)].
For a pilot study, a random sample of 181 office personnel in steel companies were interviewed about their knowledge and feelings on X-rays and other forms of ionizing radiation. The general knowledge about the beneficial and detrimental aspects of X-rays was good, with education at school and news media reports being the main sources of information (70%). In general, the news media are considered to give objective and correct reports on this matter. 85% of the interviewed held ionizing radiation to be at least somewhat dangerous. Those with higher education (college/university) were significantly more vocal on the dangerous aspects. Concerning personal fear of X-rays, 30% were at least somewhat fearful. A significant correlation was found between statements on the dangerous aspects and subjective feelings of fear (anxiety). Interestingly, there was no correlation between general fearfulness (manifest anxiety) and fear of X-rays.

[The matched-pairs differences-W-test for evaluating clinical treatment effects in matched-pair samples (author's transl)].
Starting from the U-test (see Buck 1975), for 2 independent samples of differences (e.g. pre-post differences), a corresponding test for 2 dependent samples of differences of pre- and post-measurements of 2 treatments (e.g. verum vs. placebo) is described (matched-pairs differences-W-test). Clinically relevant applications (verum vs. placebo) of the matched-pairs differences-W-test are mentioned and discussed as to their restrictions.
