Most types of fractures increase as bone density declines. But most of the knowledge about causes and prevention of fractures comes from studies performed in Western countries. Asian women appear to have similar or slightly lower bone density that may be a result of their smaller size. They appear to have a lower risk of hip fracture than Whites, which may be a result of their shorter hip axis. The risks of other types of fractures in Chinese women is less well defined and reasons for differences in the rates of osteoporotic fractures between China and Western countries remain to be explored. A study is underway in Beijing to describe the risks and potential causes of fractures among older women in urban China. Randomized trials in Western countries have demonstrated that calcium and vitamin D, estrogen, calcitonin,or bisphosphonates can reduce the rate of fractures. Increased intake of calcium and vitamin D may be the most effective approach to preventing fractures in China, but this should be tested in a randomized trial.展开更多

The author wrote it from the perspective of a film scholar whose interests focus on women directors and problems of cultural and gender identity in the contemporary cinema. Nevertheless, she decided to expand her research area to include works of Polish female artists who utilise the media and these means of expression that can be analysed in regard to modern film studies. She adopted the theoretical, feminist, and gender perspective, also applying the methodology of cultural studies in their broadest definition. This enables the author to situate the movies under discussion in diverse contexts and theoretical concepts. The purpose of the paper is thus not to offer a comprehensive or historical discussion of women＇s input into audiovisual arts of Central and East European Countries, but to emphasise complexity and demonstrate dynamics of their artistic creativity in Poland particularly. In her analysis, Radkiewicz considers four different research approaches： historical, theoretical （which refers to film and media studies）, artistic, and identity related ones. From this perspective, she investigates filmmakers＇ and artists＇ strategies of using the cinematic field, film conventions, and means of representations, which are the foundation of their narrative expression.展开更多
