大学生孝行现状调查分析*--以安徽工程大学为例

成才必先成人,成人必先懂德,而孝为入德之门也。通过对安徽工程大学大四学生的孝心观和孝行状况调查发现,当代大学生在养亲、悦亲、敬亲三个方面态度明确,但实际行动中存在各种问题。对于大学生孝行状况的改善不仅需要学生工作者进行正确理论引导,还需要大学生自身强化行孝意识,坚持发扬和践行孝道。     

网络谣言对消费者电商平台信任的作用机理研究

根据信任的特点,将消费者电商平台信任划分为认知信任和情感信任两个维度,构建了网络谣言影响消费者电商平台信任的概念模型,提出了假设,通过实证分析对假设进行了验证。结果表明网络谣言的内容特性、交互性和传播介质正向影响认知信任,信息环境负向影响情感信任,交互性、意见领袖和传播介质正向影响情感信任,认知信任和情感信任直接制约着消费者电商平台的使用意愿。     

Yer Doin’ it Wrong: How NOT to Interact with Vendors,Publishers, or Librarians

Three librarians who have extensive experience working in libraries or for publishers, vendors, or consortia presented an informal discussion on librarian–vendor relationships. The audience was encouraged to participate. Problems were articulated; speakers and audience members contributed suggestions for better approaches or behaviors when handling difficult situations.     

Electroosmotic flow hysteresis for dissimilar ionic solutions

Electroosmotic flow (EOF) with two or more fluids is commonly encountered in various microfluidics applications. However, no investigation has hitherto been conducted to investigate the hysteretic or flow direction-dependent behavior during the displacement flow of solutions with dissimilar ionic species. In this investigation, electroosmotic displacement flow involving dissimilar ionic solutions was studied experimentally through a current monitoring method and numerically through finite element simulations. The flow hysteresis can be characterized by the turning and displacement times; turning time refers to the abrupt gradient change of current-time curve while displacement time is the time for one solution to completely displace the other solution. Both experimental and simulation results illustrate that the turning and displacement times for a particular solution pair can be directional-dependent, indicating that the flow conditions in the microchannel are not the same in the two different flow directions. The mechanics of EOF hysteresis was elucidated through the theoretical model which includes the ionic mobility of each species, a major governing parameter. Two distinct mechanics have been identified as the causes for the EOF hysteresis involving dissimilar ionic solutions: the widening/sharpening effect of interfacial region between the two solutions and the difference in ion concentration distributions (and thus average zeta potentials) in different flow directions. The outcome of this investigation contributes to the fundamental understanding of flow behavior in microfluidic systems involving solution pair with dissimilar ionic species.
