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.  相似文献

This study examined the trajectories and within-person synergies of psychological processes during the final stages of matches. A process-oriented approach was used with nine women elite fencers during an international competition. Multiple assessments of perceived control, threat and challenge appraisals, problem- and emotion-focused coping, positive and negative affects were completed after each touches using video recall method. Multilevel growth curve analyses (MGCAs) indicated that winning and losing matches were each characterised by distinct psychological processes. Specifically, perceived control, challenge appraisal, problem- and emotion-focused coping, and positive affects increased linearly and threat appraisal decreased linearly for wining matches, whereas negative affects increased linearly for losing matches. Regarding the within-person synergies of psychological processes, MGCAs indicated that (1) perceived control and challenge appraisal were significantly associated with problem- and emotion-focused coping for losing matches, the strength of these associations remaining consistent across touches; (2) problem-focused coping was significantly associated with negative affects whereas emotion-focused coping was significantly associated with positive affects for winning matches, the strength of these associations remaining consistent across touches; and (3) problem- and emotion-focused coping were significantly associated with negative affects for losing matches, the linear trajectory of negative affects accelerating at times when athletes had higher levels of emotion-focused coping. Overall, this study provided insights into transactional processes during competition.  相似文献

The aim of this study was, firstly, to explore the development of primary school children’s metacognitive knowledge from preschool to the 2nd grade and the development of their text comprehension skill from the 1st grade to the 3rd grade. Secondly, the developmental dynamics between metacognitive knowledge (MCK) and text comprehension skill (CS) across the first three school years were investigated. The longitudinal sample included 181 children who were tested three times from preschool spring to the spring term of the 3rd grade using an identical set of measurements: the Metacognitive Knowledge Test and Listening and Reading Comprehension Tests. In studying developmental change using Latent Growth Curve modelling (LGC), no uni-construct effect for the development of MCK or for text CS was found. However, a slight multi-construct cumulative development between the children’s MCK and reading CS was identified. Thus, it could be cautiously interpreted that the more the children’s MCK developed from preschool to the end of the 2nd grade, the better reading CS they showed during the first three school years.

随着交际的多元化,副语言语境的影响越来越广,副语言语境在交际或信息的传递过程中产生的作用研究也越来越被人们所重视。根据副语言语境和语言语境的比较分析,归纳总结了副语言的特性。并通过分析说明副语言的特性决定着副语言语境对语言语境的影响不但体现在影响语言语境参与者的语言构建、心理、对客观事物的判断和语体选择;还能改变交际参与者的话语态度,最终导致信息交流的成功或失败等结果。  相似文献
