特殊教育教师由于其工作的特殊性,比较容易产生职业倦怠感。特殊教育教师的职业倦怠受个人因素、组织因素、交易因素和社会支持因素的综合影响,对教师自身的身心健康、学生的学业进步和社会发展产生不良影响。正念作为一种不加批判对当下进行觉察的心理品质,可以提高教师的认知灵活性、调节情绪的能力、注意力和接纳程度,从而缓解职业倦怠。特殊教育教师的正念训练可以从正念初练以觉察身心反应、情绪感知训练以接纳负面情绪、关怀与倾听训练以提升同理心三个方面展开,提高教师的正念水平并缓解职业倦怠。

Genome-wide association studies （GWASs） efficiently identify genetic loci controlling traits at a relatively high resolution. In this study, variations in major early-maturation traits, including seedling period （SP）, bud period （BP）, flower and boll period （FBP）, and growth period （GP）, of 169 upland cotton accessions were investigated, and a GWAS of early maturation was performed based on a CottonSNPSoK array. A total of 49,650 high-quality single-nucleotide polymorphisms （SNPs） were screened, and 29 significant SNPs located on chromosomes A6, A7, A8, D% D2, and D9, were repeatedly identified as associated with early-maturation traits, in at least two environments or two algorithms. Of these 29 significant SNPs, I, 12, 11, and 5 were related to SP, BP, FBP, and GP, respectively. Six peak SNPs, TM47967,TM13732, TM2o937, TM28428, TM5o283, and TM72552, exhibited phenotypic contributions of approximately lo%, which could allow them to be used for marker-assisted selection. One of these, TM72552, as well as four other SNPs, TM72554, TM72555, TM72558, and TM72559, corresponded to the quantitative trait loci previously reported. In total, 274 candidate genes were identified from the genome sequences of upland cotton and were categorized based on their functional annotations. Finally, our studies identified Gh_DoIGo34o and Gh_DoIGo34~ as potential candidate genes for improving cotton early maturity.

With the technological improvements of satellite sensors, we will acquire more information about the earth so that we have reached a new application epoch of observation on earth environmental change and cartography. But with the enhancement of spatial resolution, some questions have arisen in the application of using traditional image processing and classification methods. Aiming for such questions, we studied the application of IKONOS very high resolution image (1 m) in Xiamen City on Urban Vegetation Cover Investigation and discussed the difference between the very high resolution image and traditional low spatial resolution image at classification, information abstraction etc. It is an advantageous test for the large-scale application of very high resolution data in the future.
