婚姻:契约?制度?

婚姻不是一种契约而是制度.婚姻契约论是特定历史条件下资产阶级反封建斗争的手段,但在今天看来有失偏颇.我们应还其本来面目,承认婚姻是一种制度.     

欧盟快车:头等舱? 二等舱?

2007年1月1日,罗马尼亚正式加入欧盟。新年前夜,罗马尼亚举行了盛大的焰火晚会。假如把欧盟比作一列火车,那么坐在前面的是头等舱的15位客人,除去英国、丹麦和瑞典,欧元是头等舱客人手里必备的“车票”。只有经济总体运行良好,国内价格、财政、汇率、利率稳定的国家,才有资格捏着这张“车票”,挤到头等舱里。2004年5月1日欧盟第一次东扩增加的十个新成员,一直在为“升舱”而努力。     

和平协议:掌声?爆炸声?

美国当地时间10月15日至23日,以色列总理内塔尼亚胡和巴勒斯坦总统阿拉法特在美国总统克林顿和国务卿奥尔布赖特的直接参与下,在美国马里兰州怀伊种植园就以色列从约旦河西岸撤军等问题举行全封闭式的艰难谈判。会谈最终达成所谓“临时和平协议”,长期陷于僵局(长达19个月)的巴以和平进程得以重新启动。挽救《奥斯陆协议》的一次努力怀伊种植园的谈判是巴以美三方挽救《奥斯陆协议》的一次努力。众所周知,巴以1993年9月签署的《奥斯陆协议》,是有关各方和国际社会广泛承认的国际性条约。根据该协议,巴勒斯坦自治分三个阶段进     

Emergence of life——how and where? -An update based on recent ideas

Panspermic origins notwithstanding, life, assuming that it started on Earth, may have taken root as soon as it became geologically permissible. There are multiple possibilities for early biogenesis from complex inorganic/organic geochemistry at diverse geological niches. Recent theoretical calculations have revived the possibility of Earth having a rather reduced early atmosphere, and had refueled arguments for a surface origin of life. Laboratory modeling of possible prebiotic RNA polymerization has seen interesting experimental advances, although a plausible replicator-like molecule has not yet been produced. The hydrothermal origin school of thought has also seen an interesting postulation for life's early emergence and evolution—within contiguous, porous hydrothermal iron-sulfide (FeS) compartments, leading to a non-free living last universal common ancestor (LUCA). A confined LUCA evolving later into free-living archaebacteria and eubacteria could potentially reconcile some problems of molecular divergence between these two kingdoms. There are, however, many unresolved problems, and experimental evidence for such a scheme is lacking. Here, recent updates and refinements to the mainstay hypotheses for the emergence of life on Earth are reviewed and discussed.     

百货商场:向左走?向右走?

最近,很多大家电厂商纷纷撤离百货商场,因为他们有“国美”、“苏宁”等销售火爆的专业卖场。 世界连锁巨头“万客隆”日前宣布,北京第3家店将落户西北部,而“普尔斯玛特”在京第6家店于9月末开业。此外,世界闻名的日本最主要的便利店7—11可望明年亮相北京街头。风靡欧美的ShoppingMall也将进入中国市场。     

A supercritical carbon dioxide layer in the Hadean atmosphere for the origin of life?

Zhang et al.[1] reported the first direct detection of the natural supercritical CO2 (scCO2;critical point:31.1 ℃ and 72.9 atm) in a deep-sea hydrothermal syste...     

藤森:东方不亮西方亮?

前不久在日本参院选举中失利的秘鲁前总统藤森真是个不甘寂寞的人物——虽然身在大洋彼岸,被软禁在智利,却以"最后的武士"自诩,参加了

希腊脱欧:真心话?大冒险?

<正>1月26日,现年40岁的希腊左翼联盟党政治家阿莱克斯·齐普拉斯宣誓就任希腊新一任总理,成为希腊150年来最年轻的总理,以及首位公开反对紧缩措施的欧元区国家政府首脑。自从齐普拉斯在希腊议会选举中获胜,有关希腊退出欧元区的话题就成为国际社会关注的焦点之一。齐普拉斯的获胜是希腊社会各界对于国家长期陷入衰退、公共福利严重缩水的愤怒反映,但这种由于普遍的愤怒而带来的情绪性的选择,并不意味着齐普拉     

高科技企业:大好?小好?

在人们以往的印象中,垄断和高科技企业似乎并无太多关联,小而灵活的高科技企业似乎更易于在激烈的市场竞争中立稳脚跟。然而近些年来在高科技领域内日益强劲的兼并风的吹袭下,人们开始意识到问题似乎并非那么简单。以信息技术(IT)业界为例,我们来看看高科技领域内的垄断意味着什么?世纪之交,世界正处在由工业社会向信息社会转变的历史关头。在知识经济时代,科学技术的创新成     

新西兰:纯净的?糊涂的?

新西兰最近“摊上大事了”! 8月2日,新西兰最大的原料奶供应商恒天然公司称其一个工厂2012年5月生产的浓缩乳清蛋白粉检出肉毒杆菌,随后这一事件持续发酵.多个国家对新西兰乳制品下达进口禁令,新西兰货币在金融市场上也受到了打压.乳制品出口占新西兰出口总额的1/4,中国则是新西兰乳制品最大的出口市场.新西兰总理约翰·基在接受中国中央电视台采访时表示要深入调查事件的原因,追究相关责任,希望中国消费者能尽快恢复对新西兰食品安全性的信心.
