现代汉语中“不”字独用有两种不同的性质和三种不同的作用。“不”字独用可以表示陈述和祈使两种不同性质的语气,具有修正性、回答性、阻止性三种不同的作用,但无论何种性质何种作用,“否定性”是其最根本的特征。  相似文献   

从《白氏文集》看13世纪中朝日三地文化交流     

静永健  刘维治 《南阳师范学院学报》2009,8(1)

<白氏文集>流传朝鲜半岛与日本,白诗已成为当时跨越海域的一种文学标准.同时代的高丽王朝的李奎报与日本的藤原定家都是白诗的爱好者、研究者、传播者,因地域关系、接触版本不同,即高丽王朝是中国宋朝新开版的宋刊本,日本则是八九世纪传来的手抄的唐抄本;因而便产生了不同的受容姿态与结局,值得探究.  相似文献   

Enhancing the case for Electronic Government in developing nations: A people-centric study focused in Saudi Arabia     

Marvine Hamner  Fahad Al-Qahtani 《Government Information Quarterly》2009

The pace of implementing Electronic Government (E-Gov) is rapidly increasing. However, despite high levels of investment, a broad range of applications, and various methods of access relatively low levels of various methods of access, relatively low levels of usage (and even familiarity with e-gov) are still common. For example, in Canada, long recognized as a leader in implementing e-gov, less than 27% of Canadians used E-Gov during the past 12 months and 81% of c non-users report a low level of familiarity with either federal or provincial governmental services available through e-gov (Canada, 2004). Or, consider the showcase e-gov Gyandoot project in the Dhar district in central India, whose population is estimated at 1.7 million. Even after implementing e-gov in a showcase project for the rural poor, a study by the Center for Electronic Governance, Indian Institute of Management, Ahmedabad concluded that this model of “government to citizen” service delivery has serious sustenance problems (World Bank, 2004). The research reported in this paper takes a step back and focuses on the acceptability of e-gov by individuals. It is a people-centric approach to determine the overall acceptability of e-gov to people in a developing country, Saudi Arabia. Although this research may be generalizable to other situations, the primary intention of this project is to shed light on how to approach and manage implementation projects in developing nations.  相似文献   

What do students consider useful about student ratings?     

Tanya Beran  Claudio Violato  Don Kline  Jim Frideres 《Assessment & Evaluation in Higher Education》2009,34(5):519-527

Although measures of student ratings of instruction have been developed and examined empirically, students' attitudes about the utility of these ratings have yet to be meaningfully quantified. Using survey responses from 1229 students at a major Canadian university, we developed a psychometrically sound measure of the usefulness of student ratings. A principal components analysis with oblique rotation was conducted and three factors (Instructor characteristics, Course characteristics and Instructor's relative ranking) were obtained that explained 64% of the variance in six iterations. The usefulness of these three types of ratings information differs according to several student and course characteristics. The present results provide evidence for both reliability and validity of the instrument as an indicator of the utility of teaching evaluation for students.  相似文献   

柏拉图与墨子文艺思想之比较——从“乌托邦”谈起     

李占伟  原方 《襄樊职业技术学院学报》2010,9(1):69-71

处于轴心时代的柏拉图与墨子,可以说分别是中西方“乌托邦”思想的肇始者。虽然二者处于不同的立场,但都是以功利性为出发点服务其政治目的的,也因此引发了一系列诸如“乌托邦”、“爱的颂歌”等较为相似的思想。本文试图通过两者的比较,管窥中西艺术审美与功利关系在历史纬度上的异同。  相似文献   

太阳家家门前过——山东滕州辛绪及周边村庄的一种地方性礼俗     

秦淮 《临沂师范学院学报》2010,32(5):78-83

改革开放以来,山东滕州辛绪及周边村庄加快了从传统礼俗社会向现代社会转型,形成一种地方性礼俗：喝喜酒,不收喜礼。这一礼俗的形成既有地方历史文化渊源,也是传统文化观念在新时期同经济与社会发展相结合的产物。这一礼俗一定程度上改变了传统礼俗的形式,表现出一些新的特点,引发我们对传统与现代不同文化观念更多的思考。  相似文献   

公司债券保险的保费计算方法研究     

杨姣仕  施露芳 《黄冈师范学院学报》2010,30(3):75-77

确定公司债券保险的保费计算方法是推行债券保险工作的关键,用传统的期望值原理来计算这类型保险的保费可能会造成保险公司的保费亏空问题,对此提出一种对偶效用下的保费计算原理来计算这类型的保费。与传统的保险精算模型方法比较,这种基于股东投资后公司的资产损失的保费定价方法提供了另一个有效的解决方案。  相似文献   

后稷无父遭弃说质疑     

纪晓建 《南通师范学院学报》2010,(2):94-99

由于对以中原文化为核心的华夏上古文化重土崇实的原始宗教特点辨识不清,肇始于汉代王逸的后稷生而＂无父遭弃说＂是关于后稷弃因中影响最大、从者最众的观点,它包括＂遗腹子说＂、＂荡肠正世说＂等众多派生观点。从人类文化学角度考察,后稷神话乃是始祖崇拜造成的历史神话化的最典型代表,后稷生而见弃实乃因其出生时＂体貌硕壮、生而灵异＂。《楚辞.天问》中后稷生而能＂冯弓挟矢＂神异武功记载和在巫祝文化繁盛的南土流播的后稷战神形象均为此提供了有力的证据。  相似文献
