基于企业资产重组的工业产权战略

本文针对企业资产重组的不同目标的要求,设计了五种与之对应的工业产权战略方案：“有形资产＋商标”、“有形资产＋专利”、“有形资产＋工业产权（专利、商标）”、“专利＋商标”、“（弛名）商标＋（弛名）商标”。其根本宗旨是通过具有高度柔性的无形资产（工业产权）与具有高度刚性的有形资产组合,达到优化生产要素配置、盘活企业存量资产,以实现企业资产重组的目标。     

《中文核心期刊指南》述评

The problems existent in the Chinese core journals are approached from different aspects of library and information science. The theoretical basis of bibliometrics and the methods for measuring and selecting core journals are reviewed at full length. The introduction of the models of comprehensive evaluation is a successful example of applying fuzzy mathematics method in selecting core journals. The conclusions drawn by the authors justify Bradford's Law of Scattering, Garfield's Law of Concentration and other regularities about scientific journals.

Reading Arabic texts: Effects of text type,reader type and vowelization

While much is known about Latin orthography little is known about Arabic orthography. This study investigates the effect of vowels on reading accuracy in Arabic orthography. Participants were 64 native Arabic speakers. Four kinds of written Arabic texts were administered: narrative, informative, poetic and Koranic. Three texts of each kind were presented in three reading conditions: correctly vowelized, unvowelized and wrongly vowelized. Results indicated that vowels had a significant effect on reading accuracy of poor and skilled readers in reading each of the four kinds of texts. The results are discussed in light of the concept that more cross-cultural considerations should be made in reading theory today.
