论保证期间的性质和特征     

冯永军 《南阳师范学院学报》2004,3(10):36-39

无论在我国现行立法上还是目前理论界，关于保证期间的性质一直处于在除斥期间和诉讼时效之间徘徊不定的状况，笔认为它既不是诉讼时效，也不是除斥期间，而是独立于除斥期间和诉讼时效之外的失权期间。  相似文献   

儒家人本质论及其对传统文化影响的逻辑分析     

胡志  张宗清 《重庆职业技术学院学报》2005,14(1):126-128

尽管儒家提出了几种人性论,但只有孟子把人性善的理论上升到人本质理论的高度。由于“善”的人本质理论的内在逻辑使得中国传统文化是一种“德”的文化,伦理学发达而认识论衰微,具有积极向上、追求统一和忧国忧民的内在精神,但也造成了对妇女的轻侮和以“礼”杀人的悲剧。  相似文献   

对河图与洛书的探析     

陈锦才 《人天科学研究》1997,6(4):33-35

为了加深理解元极图理论,对比分析了河图、洛书的数理结构,得出结论：河图主先天化生后天之机,洛书含后天返先天之妙,元极图全面充分地阐述了河图,洛书的内容,而且“皇极中复有皇极”揭示了河图,洛书示曾充分表征的阴阳运变的阶段性,层次性。  相似文献   

The transfer of U.S. technology abroad     

Derek L. Bosworth 《Research Policy》1980,9(4):378-388

The causes of the transfer of technology between countries is now seen as an important dimension of the diffusion of new products and processes. Despite its obvious importance, there has been little empirical research investigating the international transfer of technology, although the work of Schiffel and Kitti (Research Policy 7 (1978)) provides a useful foundation on which to build. The research reported below tests the hypothesis that the transfer of technology between countries, as measured by the movement of patented invention, is influenced by both supply side and demand side factors. The principal variables are: patenting activity in the country of origin; the size of the recepient economy; international trade in goods and services; and the operations of multinational producing enterprises. These vaiables explain most of the variation across countries in the transfer of U.S. technology abroad. The worldwide distribution of U.S. based multinational enterprises appear to play an important part in explaining U.S. technology tranfer. On the other hand, the remaining international differences in patent law do not seem to significantly affect patent flows between countries.  相似文献

The evolution of an effective pedagogy for teachers using the interactive whiteboard in mathematics and modern languages: an empirical analysis from the secondary sector     

Derek Glover  Douglas Averis  Victoria Door 《Learning, Media and Technology》2007,32(1):5-20

There has been considerable investment in the use of interactive whiteboard technology in schools in the UK. There is evidence that whilst teachers understand such technology, many do not understand the nature and implications of interactive learning. Observation and analysis of 50 video‐recorded lessons taught by ‘successful’ teachers drawn from mathematics and modern foreign language departments in secondary schools led to the classification of three types of practice representing a spectrum of increasing interactivity. The nature of this good practice was analysed together with criteria for assessing the changes being wrought by technology in approaches to learning and teaching. The investigation concluded that the use of new technology alone cannot lead to enhanced learning. Teachers also need training to develop awareness of the relationship between approaches to interactive learning and conceptual and cognitive development in subject areas.  相似文献   

Mental Calculation Methods Used By 11-Year-Olds in Different Attainment Bands: a reanalysis of data from the 1987 APU survey in the UK     

Derek Foxman  Meindert Beishuizen 《Educational Studies in Mathematics》2002,51(1-2):41-69

This paper describes thereanalysis of data obtained in 1987 on themental calculation strategies used by asample of 11-year-olds in the course of anational survey of schools in England,Wales and Northern Ireland. The mentalskills test was administered to pupils in aone-to-one situation and the reanalysismade use of classifications of mentalstrategies developed in the past decade ininternational research. These pupils werea subsample of the main sample of about 10000 who took a written test of mathematicsin the survey, 247 taking both tests. Thescores on the written test were used todistribute these pupils into three bands ofattainment in order to compare thefrequency and effectiveness of thestrategies used by pupils of differentlevels of attainment. Eight of thereanalysed questions are discussed, each ofthem involving one of the four basicarithmetic operations. Some are purelynumerical and in others the numbers are ina context. Top band pupils mostly preferredsequential strategies which leave one ofthe numbers in the calculation complete,while the Bottom band generally preferredto split complete numbers and operateseparately on the components of the numbersthus partitioned. The most popularstrategy for Middle band pupils in severalquestions was the standard algorithm usedmentally. Complete number strategies werethe most successful for pupils in all threebands. Possible implications for theNational Numeracy Strategy in Britain arediscussed. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献
