试析我国学校德育实效低下的内在原因

由于受到现代社会市场经济的冲击和新科技、"教育全球化"的影响,我国德育面临着严峻的挑战,学校德育更是步履维艰.本文认为,除了上述大环境的影响外,导致我国学校德育实效低下有五大基本原因,即教育理念的偏差,致使学校德育丧失地位;理论研究的误区,致使学校德育无所适从;教育教学的分离,致使学校德育残缺不全;方法途径的单调,致使学校德育功效甚微;管理体制的分治,致使学校德育步履维艰.

Sleep restriction and degraded reaction-time performance in Figaro solo sailing races

Abstract

In solo offshore sailing races like those of the Solitaire du Figaro, sleep must be obtained in multiple short bouts to maintain competitive performance and safety. Little is known about the amount of sleep restriction experienced at sea and the effects that fatigue from sleep loss have on sailors’ performance. Therefore, we assessed sleep in sailors of yachts in the Figaro 2 Beneteau class during races and compared response times on a serial simple reaction-time test before and after races. Twelve men (professional sailors) recorded their sleep and measured their response times during one of the three single-handed races of 150, 300 and 350 nautical miles (nominally 24–50 h in duration). Total estimated sleep duration at sea indicated considerable sleep insufficiency. Response times were slower after races than before. The results suggest that professional sailors incur severe sleep loss and demonstrate marked performance impairment when competing in one- to two-day solo sailing races. Competitive performance could be improved by actively managing sleep during solo offshore sailing races.     

"翻转课堂"在《仪器分析》教学中的应用

"翻转课堂",是指课上的教学活动和课下的学习活动相交换,将学习的决定权从教师转移给学生,可以很好的克服传统教育的不足之处。文章结合"测量富硒康中硒的含量-原子荧光光谱法"具体实例讨论如何将这种教学模式运用于《仪器分析》课程教学中,用来改善学生学习的主动性,提高教学效果。

The structural study of Ghaffarieh Dome tile-workings in Maragheh Town based on laboratory studies

The history of using tiles in Persian architecture dates back to the eleventh century. In the beginning, tiles were made of bricks and mounted with plaster. Thereafter, however, tiles were replaced with mosaics to decorate buildings. The technique of applying mosaics began in the thirteenth century and reached its summit during the Ilkhanid and Timurid periods between the fourteenth to sixteenth centuries. One of the most outstanding buildings in which mosaics were widely used is Ghaffarieh Dome, a fourteenth-century building in Maragheh, Eastern Azerbaijan. The Dome is especially noteworthy for its unique mosaic workings. Therefore, a thorough examination of the mosaics used in the Dome may pave the way for closer studies of the Ilkhanid mosaics (tile-workings) in Iran. Since there is little information on the material aspects of mosaics used in the Ghaffarieh Dome, the body and glaze of the mosaics were examined through instrumental analyses. In order to interpret the results of the analyses, they were compared with existing data about similar mosaics of Islamic lands. The presence of pyroxene (aluminum diopside) in some of the mosaic bodies revealed that the firing temperature limit in the kiln was not, most likely, uniform. Two kinds of glazes, alkaline and lead-based, were used to produce black and turquoise colors.     

On the impact of early marriage on schooling outcomes in Sub-Saharan Africa and South West Asia

This paper examines the effect of age of marriage on women's schooling outcomes for 36 countries from Sub-Saharan Africa and South West Asia. We employ an instrumental variable approach to account for the endogeneity of early marriage driven by socio-economic and cultural factors. Our results show that delaying early marriage by one year is associated with an increase of half a year of education in Sub-Saharan Africa and nearly one third of a year of education in South West Asia as well as a lower likelihood of dropping out from secondary school of 5.5% in South West Asia.
