有关“曹雪芹书箱”问题考两则

<正>一、"一拳石"不能证雪芹书箱为伪造从2009年年初开始,各家红学网络上,关于所谓曹雪芹书箱真假的问题又被很多人提起来。其中,有一个传为某专家主伪的意见引起了我的兴趣。此观点认为书箱是伪造的,核心证据是什么呢?正如红学研究者于鹏所言:问题的核心是与补天有关的"一拳石"出于富竹泉的诗句,此诗被其外孙冒充曹雪芹诗中,而号称曹雪芹书箱的箱子上偏偏有这个"一拳顽石"。     

在爱情与革命的浪漫畅想间——张闻天长篇小说《旅途》及书写策略

张闻天的长篇小说《旅途》是一部充满着精神自居感的爱情与革命的浪漫畅想曲。作者以浪漫主义的精神,确立了书写爱情与革命的新策略:即自居的精神气度凸显主人公王钧凯人格精神的独立品格,赢得爱情的自主权;以共同的叛逆性格与理想的革命诉求彰显双方内在的情感动因;以精神的共鸣升华爱情的崇高感。在环境表现上,以自负的心态化历史事实为心理事实,同构爱情与革命的精神动力。这种强烈的具有精神自居感的浪漫主义书写图式,是五四新文学反帝反封建的浪漫主义精髓的承续,它不仅开启了革命文学的先河,也创造了革命文学的新范式,为后来的革命文学创作提供了可资借鉴的蓝本。

Training and changes in fluid and crystallized intelligence

In this study, the same battery of tests was administered three times: at the beginning of the experiment, at the end of training, and 1 year after the end of training. The control group was taught in the traditional way. The experimental group was given extensive training in creative problem solving over a 3-year period. The invariant factor structure model for multimode data (R. P. McDonald, 1984, in Research methods of multimode data analysis, New York: Praeger Scientific) was fitted, with LISREL, to both groups simultaneously. At the last testing session, the experimental group performed better than the control group on a majority of variables. Fluid intellectual abilities were somewhat more affected by training in creative problem solving than were crystallized abilities.     

青少年跳水运动员生长发育状况的评估

目的：了解上海青少年跳水运动员的发育状况,探讨较为科学实用的评估方法。方法：采用X线骨龄测试、第二性征评价、神经内分泌激素检查、性腺超声检查等方法,为青少年运动员进行发育评估。结果：共20名运动员,其中50%骨龄落后于生活年龄,40%第二性征Tanner分期落后1期;对4名落后较明显的运动员进行性腺超声检查、神经内分泌激素检测和LHRH兴奋试验,其中1名运动员诊断为体质性青春期延迟。结论：上海青少年跳水运动员较多存在骨龄与第二性征落后现象,个别出现体质性青春期延迟。
