This paper presents data arising from a tracer study of 90 terminating Beirut upper secondary school students. Nearly all the students intended to transit to university, about half of them to science and technology programmes, and subsequently did so. Median anticipated earnings upon graduation were realistic, but a lack of information or guidance about higher education and career options was noted by a considerable proportion. The results of the study are discussed with reference to the as yet poorly elucidated dynamics of schooling with regard to attrition and transition to higher education and employment in Lebanon.  相似文献

试论“现代文化”的理论与实践   总被引：1，自引：0，他引：1  

牛汝极 《新疆师范大学学报(哲学社会科学版)》2011,(3):1-14

文章认为,现代文化是指人们适应现代化本质要求的文化,就是实现文化的现代转型并建设现代价值、形成现代认同、张扬现代精神并进而建设共同信仰的文化。现代文化的主要内核与社会主义核心价值体系和社会主义价值观体系存在着一致性和耦合性。现代社会的现代价值、现代认同、现代精神和文化的现代转型是现代文化及其建设的核心内容和主要任务。现代价值是现代文化的基础,现代认同是现代文化的支撑,现代精神是现代文化的动力,文化现代转型是现代文化建设的途径,建设现代文化的目标就是建设信仰共同体。现代文化的这四个要素相互依存,相互补充,相互作用,紧密联系,现代文化是先进文化发展过程中的一个环节。文章还提出了新疆"疆魂"的概念以及实现文化现代转型的途径。  相似文献   

康托实数集合不可数证明中的四种错误探析     

欧阳耿 《喀什师范学院学报》2011,32(6):17-21

从逻辑、无穷观、极限论和证明的思路及具体的操作过程,分析了新发现的康托在实数集合不可数证明中所存在的四种错误,得到＂由于与现有经典无穷理论体系、经典极限论和经典数量体系密切相关的数学基础理论中所存在的缺陷,康托在这类证明中无法回避这四种很严重但却很隐蔽的错误＂的明确结论.特别是其中的逻辑错误使这样的证明无意中成了一种典型的数学魔术.  相似文献   

高原-亚高原-平原过渡训练对世居高原中长跑运动员心肺功能影响的初步研究     

阳仁均  殷劲  钱钰  蒋丽 《四川体育科学》2015,34(3)

目的:初步探讨"高原-亚高原-平原"过渡训练对世居高原的中长跑运动员心肺功能的影响.方法:通过对18名甘孜州世代居住在海拔2 500m以上的中长跑运动员在高原训练后进行"高原-亚高原-平原"过渡训练,训练结束后分别在高原、亚高原、平原分别采集其与心肺功能相关的生理生化指标,对高原-亚高-平原过渡训练对世居高原的中长跑运动员心肺功能的影响进行初步研究.结果:经分析发现训练结束后测得从康定到泸定再到都江堰的最大摄氧量、血乳酸、血氧饱和度、尿蛋白均呈递增趋势,心率呈递减趋势,且除尿蛋白外各项指标均存在显著性差异(P<0.05).结论:高原-亚高原-平原过渡训练有利于提高世居高原中长跑运动员的心肺功能的适应能力.提示:高原-亚高原-平原过渡训练心肺功能的变化有利于运动员更快更好的适应从高原到平原的海拔落差,对运动员训练时运动强度的提升和成绩的提高提供运动生理学依据.  相似文献

基于翻转课堂的大学逻辑教学改革     

李章吕 《毕节学院学报》2015,(5):45-49

“逻辑教学现代化”是我国学界在1978年提出的口号,旨在改变我国逻辑研究和教学较为落后的现状。但30多年过去了,我国的大学逻辑教学却依然存在许多困境,呈现出萎缩态势“。翻转课堂”是当今国际教育改革的前沿,其教学理念和教学模式对于我国的大学逻辑教学具有重要的启示,对于解决我国大学逻辑教学所面临的困境具有重要的现实意义,也是全面实现“逻辑教学现代化”的重要工具和途径。  相似文献   

Interactions between Niche and Regime: An Analysis of Learning and Innovation Networks for Sustainable Agriculture across Europe

Abstract

Purpose: This paper aims to reveal, and contribute to an understanding of, the processes that connect learning and innovation networks in sustainable agriculture to elements of the mainstream agricultural regime. Drawing on the innovations and transition literature, the paper frames the analysis around niche-regime interaction using the notion of niche-regime compatibility.

Design/Methodology/Approach: 17 Learning and Innovation Networks for Sustainable Agriculture (LINSA) engaged in agricultural food production, non-food and rural development were analyzed. In line with the project's transdisciplinary approach data were collected in a series of participatory workshops.

Findings: Five modes of LINSA-regime interaction are distinguished based on compatibility. The level of LINSA-regime compatibility influences the extent of the diffusion of LINSA ideas and practices into the regime. However, interaction processes within these modes reveal multiple and diverse connections between LINSA and regime entities suggesting a more complex relationship exists.

Practical implications: A range of connecting processes and activities (for example, certification, exemption from regulation, facilitation of networking) can bring about effective LINSA-regime interaction and could be externally supported.

Originality/Value: Empirical evidence from 17 case studies provides valuable insights from a number of different contexts across Europe. By directing analysis of interaction at the level of LINSA (niche project), rather than at the macro level, the study offers an original perspective. It suggests that the transition to sustainable agriculture might be understood as a complex of interactive processes leading to a series of adaptive changes, rather than as regime change.  相似文献   

Modeling the developmental trajectories of rational number concept(s)     

《Learning and Instruction》2015

The present study focuses on the development of two sub-concepts necessary for a complete mathematical understanding of rational numbers, a) representations of the magnitudes of rational numbers and b) the density of rational numbers. While difficulties with rational number concepts have been seen in students' of all ages, including educated adults, little is known about the developmental trajectories of the separate sub-concepts. We measured 10- to 12-year-old students' conceptual knowledge of rational numbers at three time points over a one-year period and estimated models of their conceptual knowledge using latent variable mixture models. Knowledge of magnitude representations is necessary, but not sufficient, for knowledge of density concepts. A Latent Transition Analysis indicated that few students displayed sustained understanding of rational numbers, particularly concepts of density. Results confirm difficulties with rational number conceptual change and suggest that latent variable mixture models can be useful in documenting these processes.  相似文献
