The effects of attitudinal versus religious similarity on the neighborhood preferences of Lebanese university students

The main purpose of the present study was to assess the relative importance of attitudinal versus religious similarity on the neighborhood preferences of Lebanese university students shortly after the 1975–1976 war in Lebanon.It was expected that neighborhood preference for a stranger would be affected by: (1) attitudinal similarity — dissimilarity on an important political issue and by (2) the number of strangers involved.The subjects were 169 Lebanese undergraduate students at the American University of Beirut (67 Christians, 96 Muslims, with six subjects not mentioning religious affiliation). In terms of political ideology, 38 subjects were conservative while 131 were liberal and, with respect to displacement during the war, 81 subjects stated that they were displaced while 88 subjects indicated that they remained in their original neighborhoods. Finally, with respect to ethnic (or national) origin, 118 subjects considered themselves as “Arabs” while 48 indicated that their origin was something “other” than Arab, with the remaining three subjects not responding to this item.The results showed that, irrespective of the background characteristics of the subjects, (1) strangers of a different religion who had the same attitudes on an important political issue were significantly more preferred as neighbors than coreligionist strangers who had opposite attitudes on the same issue, and (2) neighborhood preference was significantly greater for one than for many strangers. However, although one stranger was significantly more preferred as a neighbor than many, this preference was found to be stronger under the opposite attitude — same religion condition.

Ni_3Al合金的价电子结构

利用固体与分子经验电子理论(EET)研究了Ll2型N(i)3 Al有序晶体结构,在采用键距差方法计算时,共考虑四种共价键.根据键距差最小的原则,确定N(i)3 Al中实际的原子状态为:A:13, AlM的杂阶为为A:4.     

“数 ＋量 ＋动”结构的名词性及其生成机制

借鉴构式语法理论对“数＋量＋动”结构进行分析。在典型构式“数＋量＋名”的基础上形成的“数＋量＋x”构式,其构式义有三项内容,即1、“数＋量”对“X”进行计量;2、构式整体上是名词性的。且这种名词性不随其内部成分的变化而变化;3、X位置上的词语在该构式的层面上表现为名词性。而在语义层面上这个位置上的词语可以是名词,也可以是动词、形容词等。因此,“数＋量＋动”作为非典型构式,是典型构式“数＋量＋名”的继承和引申,其“动词”及整个结构的名词性是“数＋量＋X”这一构式赋予的,是一定认知机制制导下构式压制的结果。     

图书情报学高被引论文引用现象的实证研究

学术论文是科研活动产出和知识信息交流的主要载体,而学术论文被引用则是学术成果获得认同的主要方式之一。研究高被引论文所引用论文的分布特征,对于了解高被引论文知识基础的构成具有重要意义。本文以ISI图书情报学（Information Science & Library Science）为例,以实证研究为基础,按比例采集图书情报学领域的高被引论文数据,查询这些高被引论文的参考文献的被引频次数据,以期得到高被引论文的引证特点。研究发现,图书情报学领域的高被引论文更多地引用了高被引参考文献;随着被引频次的降低,其引用的高被引论文所占的比例也在下降。     

溶剂调控谷氨酸衍生物自组装纳米结构的研究

通过调节溶剂中水的比例来调控N,N'-二谷氨酸-3,4,9,10-苝四甲酸二酰亚胺(GP)的自组装行为.通过扫描电子显微镜(SEM)、红外和紫外等手段对组装结构进行了表征.结果表明溶剂对N,N'-二谷氨酸-3,4,9,10-苝四甲酸二酰亚胺(GP)自组装过程影响较为显著,导致形成不同组装纳米结构.这归因于水溶剂参与了分子间的组装过程,从而调节了分子间的相互作用力.     

《张生煮海》与《柳毅传》的形象特征

“在N的V下”与主句表因果时的词语表征——兼及相关情况

对"在N的V下"与主句间在表示因果关系时表现出的一些能够体现原因和结果意义的特征性词语及相关情况作了初步的考察和分析。主要结论是:(一)有时为了强调结果产生的原因,结构的上文用上"正是"一词;中心语动词前出现含有程度的形容词语或副词,这更容易使主句产生某种结果;不少情况下,结构中原因所涉及的内容是对上文相关内容的复指性的概述。(二)主句中所表示的结果意义有两种类型:一是由于某种原因而出现了某种结果;一是由于某种原因而出现了某种变化;用于体现结果意义的重要词语,主要有表被动/使动/遭受/无奈等意义的词语、结果义动词词语、各种意义的副词和程度/速度义形容词等。     

多彩太阳电池的制备及性能研究

研究了不同颜色太阳电池的制备工艺和电学性能。实验表明,随着镀膜压强的增加,减反射层的折射率缓慢增加,当压强超过1800 mTorr时,折射率的增幅变大;随着镀膜时间的增加,太阳电池的开路电压Uoc先增大后减小,当淀积时间为550 s时,Uoc达到最大值;短路电流Isc随淀积时间的变化趋势与Uoc相同,当淀积时间为650 s时,Isc达到最大。因此,对于具有装饰功能的太阳能电池组件采用并联的方式进行设计可达到最佳组件效率。
