Nearly 300 matched British and Japanese participants completed an equivalent three-part questionnaire in their native language. The questionnaire covered general beliefs or conceptions about schizophrenia, causal explanations for the aetiology of schizophrenia, as well as the role of hospitals in particular, and society in general, in helping schizophrenics recover from their illness. It was predicted that the Japanese, who have more taboos about mental illness than the British, would see schizophrenics as more difficult, dangerous and "morally insane". Factor analysis of each of the three parts of the questionnaire yielded a clearly interpretable structure. The British were more concerned with the rights of schizophrenics and believed them to be less dangerous and abnormal than did the Japanese. The Japanese favoured sociological (stress) explanations more than the British for the cause of schizophrenia. Whereas the Japanese saw micro- and macro-society change as the best way to help schizophrenics, the British stressed individual care and consideration as more relevant.
Grain growth of ZnO in liquid phase sintering of ZnO–0.5 mol%Bi2O3 ceramics has been studied by increasing the doping amount of Al2O3 from 25 ppm to 200 ppm. Al2O3 was doped using an aluminum nitrate aqueous solution. When 50 ppm of Al2O3 was doped to ZnO ceramics, abnormal grain growth was observed, while 75 ppm Al2O3 retarded grain growth. Doping of Al2O3 to pure ZnO ceramics did not cause abnormal grain growth,but simply retarded grain growth . The ratio of diameters of these grain sizes sintered at 900° C: d (abnormal grain growth)/d(retarded grain growth) is 20–100. Mechanisms of abnormal grain growth and retardation are proposed as follows. When the doped amount of Al2O3 was 50 ppm, aluminum compound thin films which were formed around ZnO grains at a low temperature and retarded grain growth disappeared suddenly by diffusion into the ZnO grain and ZnO grains grew suddenly. When the doped amount of Al2O3 was 75 ppm and the aluminum compound film was thick enough, part of the film remained unchanged even when a considerable proportion of the aluminum diffused mainly into the ZnO to reach solubility, retarding grain growth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
