沙中精魂

从空中俯瞰，刻画在沙漠上的线条仿佛长时间暴露在阳光下的画作，轮廓已模糊难辨。飞行员在秘鲁南部纳斯卡镇以北的荒漠高原上空急转盘旋，我只能依稀辨出地面上一系列描绘精美的图形。     

孙中山与苏联

卓越的中国民主主义革命家孙中山先生是世界第一个苏维埃国家的真诚挚友。 早在19世纪末,当孙中山先生第一次前往英国期间,他就开始了解俄国的革命运动。1897年,他在伦敦一个图书馆结交了数位侨居国外的俄国民粹派革命家,其中一位是伏尔霍夫斯基。此人在俄国发表孙中山两篇文章的译文起了很大作用。孙中山在伦敦时,曾被人诱     

Marital instability in a rural population in south-west Uganda: implications for the spread of HIV-1 infection

"The aim of this study was to examine people's beliefs about the causes of marital instability in a rural population cohort in south-west Uganda. Results from a baseline survey of HIV-1 infection in the cohort of over 4,000 adults (over 12 years old) showed a twofold increase in risk of infection in divorced or separated persons when compared with those who are married. A purposive sample of 134 respondents (seventy-two males, sixty-two females) selected to represent different ages, religions and marital status were asked in semi-structured interviews to comment on the reasons for continuing marital instability in their community. The most common reasons suggested for marital instability were sexual dissatisfaction, infertility, alcoholism and mobility....HIV infection was not mentioned as a direct cause of separation, but a small independent study revealed that seven out of ten couples separated on learning of a positive HIV test result of one or both partners. Marital instability is not uncommon in this population; there is evidence that HIV infection is making the situation worse." (SUMMARY IN FRE)
