学校本位教学视导模式的实证研究——以兰州市E中学为例

本研究目的在于通过对兰州市E中学施行的学校本位教学视导模式的深入观察,全方位了解学校本位教学视导模式的具体运作方式。以兰州市一所薄弱学校为研究场域,通过课堂观察的方式,全面了解学校为提高办学质量所开展的“学案分组教学法”,及进行学校本位化视导模式的具体运作状态。在兰州市E中学开展学校本位教学视导模式的过程中,学校校长与某大学教育学院课程与教学领域的教授专家参与视导过程。主要采取校长主导,专家参与的合作视导方式,对兰州市E中学初中二年级屈老师数学课进行为期一周的教学观察与记录。实施以学校为本位的合作视导方式,目的在于发现兰州市E中学进行“学案分组教学法”中的具体教学问题,通过大学与中学的合作,开展学校本位视导模式,有效促进教师的专业发展与增强教学有效性,提高学校办学质量。     

实施系统工程，实现高校思想政治工作的创新

新时期的高校思想政治工作更加复杂化，任务更加艰巨，这就要求我们因事而化、因时而进、因势而新，不断研究新情况，探索新办法，不断开创高校思想政治工作新局面。总结了信电学院的做法，实施系统工程，打组合拳，为高校思想政治工作提供了新的思路。     

审美现代性视野中的米兰·昆德拉

与卡林内斯库的审美现代性理论不同，米兰·昆德拉提出的“欧洲小说”观念，是以审美现代性对抗“资产阶级的现代性”的源头所在。米兰·昆德拉在小说理论和创作实践中展现出了对资产阶级的启蒙现代性的批判，和对审美现代性立场的坚执中产生的反省，阐述了他独特的“欧洲小说观”与审美现代性起源新说。他站在小说家的立场上，以审美现代性的态度，审视和评判现代生活，深入地考察了现代人生存中的一系列现象：媚俗，舞者，轻与重，快与慢，记忆与遗忘，革命、鸟托邦与抒情姿态，等等，犀利地揭示出其中的现代性悖谬。     

“Last Night,I Did a Striptease for My Husband”

Representations in popular media at the end of the twentieth century and the beginning of the twenty-first suggest that North American culture idealizes a kind of femininity constituted in erotic display while at the same time disavowing the parallel performance of that femininity in strip culture. This paper begins to consider why femininity is so insistently constituted on these terms, focusing in particular on women's advice media, self-help, and exercise programs of erotic dance as a domestic activity, and working to identify and understand the implications of that representation, for women who work as erotic dancers and for women who do not, with reference to the ways in which these two categories of femininity are constituted and maintained as separate categories through representation and to the effects of this separation for the labour of erotic dance and for the performance of femininity in the everyday. This paper undertakes to understand this complicated relationship and to determine what precisely is at stake in such representations, how to read them, and what they mean.     

对光速理论相关问题的辩证唯物主义审视

"奥佩拉"项目结果所显示中微子超光速现象,激发"反例验证"和"理论审视"两方面工作。本文主要用辩证唯物主义原则对"光速不变原理"相关概念含义进行审视,尝试从主客对应、概念指意、过程实现等角度揭示可能隐潜着的一些问题,并给出了一些可能性的"切削"。

Appropriate use of bright light promotes a durable adaptation to night-shifts and accelerates readjustment during recovery after a period of night-shifts

Abstract

The present study examines the stability of bright light circadian readjustment during two consecutive dim light night-work periods and circadian synchronization during the recovery after a night-shift period. A sample of 10 subjects was divided into 2 groups (control group: 6 subjects; experimental group: 4 subjects). All subjects worked during 5 days, between 23:00 and 07:00 h and then went to sleep. Subjects received 2500-3000 lux between 02:00 and 05:00 h during 5 days for the control group and 3 days for the experimental group. During recovery after the night-shift periods, three cycles of bright light were administered at two different times: 12:00-15:00 h for two of six subjects from the control group and 10:00-13:00 h for all subjects (4) of the experimental group. By the fifth cycle of night-work the maximum of urinary aMT6s excretion that occurs at 05:00 h in the baseline condition was shifted to 12:00 h for the control and experimental groups (delay in hours: 7±1.6 (control); 7±1 (experimental)). This result suggests that three cycles of bright light are sufficient to induce a significant phase delay and that this delay remained stable when night-work proceeded under dim light. The phase delay of the circadian aMT6s excretion by exposure to bright light was accompanied by an improvement of the quality of day sleep and level of cognitive and psychomotor performances for control and experimental groups. No significant difference was observed in the two groups for daytime sleep and nocturnal performance. The two bright light periods used during the three days of recovery induced a complete synchronization in five of six subjects. One subject showed a partial synchronization probably because he remained at the laboratory under dim light during the day and had few family and social contacts.     

普通话水平测试中的轻声评判

轻声是普通话水平测试中测试员评判难点之一。测试员在评判时,要把握普通话轻声词的范畴;掌握轻声读音失误类型及评判原则;根据是否具有辨义作用,区分对待“朗读”、“说话”中轻声读音错误的扣分归属。     

Psychophysical conditions and hormonal secretion in nurses on a rapidly rotating shift schedule and exposed to bright light during night work

The psychophysical conditions of 15 young female nurses, working in a rapidly-rotating shift system (2-2-2-2), modified according to some psychophysiological criteria, and exposed to short period (4 × 20 min) of bright light (2350 Lux) during their night duty, were studied in order to evaluate their adaptation to night work and to test a possible positive effect on it of bright light. Subjective evaluations of work load and psychophysical conditions, performance measures, hormonal excretion (cortisol, 6-sulphatoxymelatonin and catecholamines), oral temperature and activity-sleep logs were taken during the shiftwork cycle, comprising one morning, one afternoon and two consecutive nights under normal and bright light. The results showed that this rapidly-rotating shift system had little effect upon the normal circadian rhythms of the body. Moreover, the lengthening of the night shift to 10 h can be considered to be acceptable, provided that work load is reduced and there are sufficient rest pauses available. On the other hand, the reduction to 7 h of the length of the day shifts and delayed start of the morning shift to 07:00 h appeared to be convenient both in relation to the work load and sleep duration. Some positive effects of bright light upon psychophysical conditions and performance efficiency were noted, while hormonal excretion and body temperature did not show any effect of bright light; in particular, melatonin excretion was not suppressed appreciably by the bright light used.     

建筑摄影艺术探讨

建筑摄影的宗旨是用二维空间的照片表现出三维空间的建筑物 ,建筑摄影的确切概念应是纪实性与艺术性的统一 ,建筑摄影是用摄影传播表现建筑文化与艺术 ,是其它手法所不及的。从建筑摄影分类及透视“失真”控制谈起 ,就光的微妙变化来捕捉精彩瞬间 ;用光来表现质感 ;用光的方向、品质、色彩讲述对物体视觉的影响来说明光在建筑摄影中至关重要 ,最后从实践操作角度讨论了视点的选择
