“银元兑换券”在青海流通、使用情况述略

一九四九年七月,随着《银元及银元兑换券发行方法》的颁布,银元券被运到西宁,但直到九月初西宁解放前,国民政府中央银行西宁分行一直未能“奉令发行”。西宁分行既未“奉令发行”银元券,又元“奉拨”的银元可供兑换银元券,当时的政治,经济和军事等诸方面原因导致银元券在青海地区出现了这种特殊现象。

机能主义心理学:从芝加哥学派到哥伦比亚学派

本文比较了机能主义心理学内部芝加哥学派和哥伦比亚学派在研究倾向上的差异，认为这种差异使心理学研究从心灵主义迈向客观主义并成为一个连续的过程，而机能主义出于这个连续过程的过渡环节。其中艺加哥学派主要是在与构造主义的斗争中确立了机能主义的基本立场和原则；而哥伦比亚学派把研究的侧重点由理论探讨转向对具体问题的研究，因此在具体研究成果的获得和研究方法的拓展方面贡献显著，为日后行为主义的产生奠定了先前基础。     

试论《新民丛报》在中国近代文化史中的地位

《新民丛报》是近代中国介绍和传播资产阶级思想化的重要刊物，它在把握中国近代化发展方向，推进近代化向前发展方面作出了很多贡献。《新民丛报》虽然在启蒙宣传上还存在着不足，但它毕竟给当时封闭的中国思想界带来了许多西方资产阶级的新理论和新化，开创了中国资产阶级的新学术，做了前人和同时代人没有做或做得不够的事情，并产生了广泛的社会影响，因而在中国近代化史中占有十分重要的地位。     

当代大学生体育兴趣的研究

研究旨在系统了解当代大学生体育兴趣现状并发现存在的主要问题,为进一步深化学校体育改革提供依据.研究表明,有82%的大学生对体育活动抱有兴趣,健身、调节心理与娱乐是大学生参加体育活动的主要价值取向;场地器材短缺、体育课不能使学生获得良好的心理生理体验,是影响学生体育兴趣的主要因素.建议增加学校场地、器材设施的建设,改革体育教学,加强学生课外体育活动组织建设,培养和激发学生的体育兴趣.

How do people read the passages during a reading comprehension test? The effect of reading purpose on text processing behavior

In this study, we investigate the effect of reading purpose on students’ processing behavior during a reading comprehension test. In a repeated measures design, sixty undergraduates answered multiple-choice (MC) reading comprehension questions in a condition with no overarching goal for reading and in an alternate condition where the same students were first provided with the goal of summarizing the text before answering MC questions. Results from eye tracking analysis showed that when students read and answered questions without an overarching goal, they spent much less time reading the passages before answering the questions, more time re-reading the texts while answering the questions, and more time on parts of the text that were not necessary to answer the questions. We conclude that providing examinees without an explicit goal for reading may inadvertently encourage a “search for the answer” reading process, rather than on building a coherent mental model of text content.     

Investigation on apoptosis of neuronal cells induced by Amyloid beta-Protein

Objective: To construct a PC12 cell strain with neuronal differentiation, and observe the apoptosis and pro-liferation activity effects induced these cells by Amyloid beta-Protein (Aβ-43). Methods: 1) PC12 cells in logarithmicgrowth phase were subcultured for 24 h. After the culture fluid was changed, the cells were treated with Rat-β-NGF andcultured for 9 days. 2) Neuronal differentiation of PC12 cells in logarithmic growth phase were divided into four groups:control group (0), experimental group (1), experimental group (2) and experimental group (3). The concentrations of Aβ inthe four groups were 0 μmol/L, 1.25 μ mol/L, 2.5 μ mol/L and 5 μmol/L, respectively. The cells were harvested at 24, 48 and72 h later and stained with AnnexinV-FITC/PI after centrifugation and washing. Then flow cytometry was conducted toexamine the apoptosis percentage. 3) NGF-induced PC12 cells were selected and Aβ with different concentrations wasadded. The final concentrations of Aβ were 0 μmol/L, 1.25 μmol/L, 2.5 μmol/L and 5 μ mol/L, respectively. After the cellswere incubated in an atmosphere of 5% CO2 at 37 ℃ in an incubator for 72 h, the OD values were examined. Results: 1)Neuronal differentiated PC 12 cell lines were successfully established. 2) Flow cytometric examination indicated that Aβ(1.25, 2.5, and 5.0 μmol/L) could effectively induce apoptosis of neuronal-differented cells at the 24 h, 48 h and 72 h timepoints. 3) Aβ (0-5.00 μ mol/L) had no obvious effect on proliferation or restraining of the neuronal differentiation of thePC 12 cells after a 72 h interacting process. Conclusion: This investigation revealed successful neuronal differentiation of thePC12 cell strain. The induction of apoptosis of the neurocytes by various concentrations of Aβ was observed and the in-fluence of Aβ on induced proliferation of PC 12 cells by Rat-β-NGF was revealed. This study -05 provide basis for futureresearch on the molecular cure of AD and interdiction of AD evolution.     

信息社会下高等职业院校图书馆服务模式创新研究——以湖州职业技术学院图书馆为例

图书馆是信息资源中心,特别是高等职业院校图书馆,因其馆藏技术性、实用性强,一直在我国职业教育中发挥着举足轻重的作用。信息网络技术的迅猛发展对图书馆信息服务形成了巨大冲击。本文在分析传统图书馆服务弊端、信息化网络化对传统图书馆的冲击以及新形势对图书馆服务新要求的基础上,分析了新形势下图书馆服务的转型方式。并以湖州职业技术学院图书馆转型升级为例,总结了其该图书馆服务创新的举措,说明了其服务创新的效果,分析了仍存在的问题和完善措施,阐述了在信息化网络化的新背景下,图书馆工作人员要以读者中心、以服务为根本,通过提高自身素质、转变服务理念,才能让图书馆更好地发挥其信息资源中心的作用。
