一项新的研究得出这样一个结论:以有音调语言(如汉语)为母语的音乐家与以无音调语言(如英语)为母语的音乐家相比,前者的音高辨别力会更强些,因此可以这么说:中国人比英美人更有成为音乐家的天赋!

当前的美澳同盟已经被赋予新的时代内涵。冷战期间,《澳新美同盟条约》被定义为亚太地区安全防御能力的关键因素。从历史上看,美国和澳大利亚的防务和安全合作利益促进了亚太地区联盟的网络化。如今,“印太战略”的两个关键因素是自由开放的印太政策的建立和中国的崛起。由于中国的崛起事关重大,对自由开放的印太政策的主要参与者和威胁的概念界定应该成为评估美澳在印太地区开展防务和安全合作的出发点。这一同盟网络中的国家将需要评估它们与美国和澳大利亚的安全利益,以及它们与崛起的中国的经济利益。本文据此认为,尽管美国和澳大利亚在自由开放的印太政策下的防务和安全合作前景很好,但是其他印太国家的能力和意图目前仍存在不确定性。

Journal of Forestry Research 2016年第1期27卷 91-99页

Use of legume trees can improve soil quality in degraded pastures. The aim of this study was to charac- terize C and N mineralization kinetics and estimate the potentially mineralizable C and N in soil under Mimosa caesalpiniifolia Benth. and Acacia auriculiformis A. Cunn. ex Benth. secondary forest and pasture in red-yellow latosols in southeast Brazil. We conducted a laboratory aerobic incubation experiment using a completely ran- domized design of four replicates and four types of plant cover using a modified version of the Stanford and Smith technique （1972） to study C and N mineralization potential. Potentially mineralizable N （No） ranged from 135 to 170 mg kg-1. The predominant form of mineral N for all types of plant cover was N-NO3-. M. caesalpiniifolia was the only species that had a positive influence on N min- eralization. Neither of the legumes influenced C mineral- ization in pasture or secondary forest. The model of N mineralization corresponded to a sigmoidal curve while C mineralization corresponded to an exponential curve, revealing that the N and C mineralization processes were distinct. N mineralized by M. caesalpiniifolia （216 kg ofN ha-1） was adequate to meet the N requirement for a livestock-forest system.

值得一提的是,本文是近半年来发表的对monroe ***的第三篇学术访谈。第一篇是与西班牙IE大学传播学院院长Samuel Martin-Barbero有关全球政治传播的对话,同时以西班牙语和英语刊登在该校学报上,可谓欧洲的视角;第二篇是回答香港中文大学新闻与传播学院教师的提问,由该校的丘林川教授设计实施,以英文刊登在Chinese Journal of Communication九月号上;此篇则是与中国大陆学者的对话。纵观三篇访谈或可相映成趣,从中折射出多元的视角和更为全面、立体的内容。笔者亦希望藉此展现中美学者眼中的传播、中国与世界,展现东西方不同语境所形成的在相关概念、议题上的认同与差异。

一冬日里难得的晴天,阳光在雨后微湿的空气里泛起温暖的香味。站在热气球俱乐部门口,夏里不住地在心里给自己打气,然后一咬牙推开了门。大方桌前围坐了十几个人,都因为她忽然的闯入而鸦雀无声。夏里僵直地站着,头皮微微有些发麻。久野坐在人群中间,随他们的目光看向她,夏里忽然觉得呼吸有些困难。"我叫夏里,虽然有恐高症,但真心想加入热气球社!"方桌前爆发出一阵哄笑。
