共享经济可持续性评价：社会感知与客观绩效     

董晓松  霍依凡  赵星 《科研管理》2023,44(1):79-88

共享经济行业可持续性评价的社会感知和客观绩效不一致将造成认知错位、投资误判和政策失效等结果。本文在线挖掘2017—2019年我国主要社交媒体上29 771条文本信息，并收集行业统计数据，综合测度共享经济行业的可持续性并比较其差异。研究发现：社会公众并不认为共享经济行业具有显著的总体可持续性，而且行业实际绩效展现的可持续性与社会大众认知截然不同。进一步发现：受限于主观认知能力，社会公众认为共享经济可持续性主要来自可观察到的行业外部经济和外部生态等维度，但客观绩效表明共享经济行业内部的经济和外部的技术优势才是其可持续性的重要支撑。此外，二者评价的差异在住宿与医疗等产能共享内部过程不易被大众观察的行业中最为突出。  相似文献   

Reliably Assessing Growth with Longitudinal Diagnostic Classification Models     

Matthew J. Madison 《Educational Measurement》2019,38(2):68-78

Recent advances have enabled diagnostic classification models (DCMs) to accommodate longitudinal data. These longitudinal DCMs were developed to study how examinees change, or transition, between different attribute mastery statuses over time. This study examines using longitudinal DCMs as an approach to assessing growth and serves three purposes: (1) to define and evaluate two reliability measures to be used in the application of longitudinal DCMs; (2) through simulation, demonstrate that longitudinal DCM growth estimates have increased reliability compared to longitudinal item response theory models; and (3) through an empirical analysis, illustrate the practical and interpretive benefits of longitudinal DCMs. A discussion describes how longitudinal DCMs can be used as practical and reliable psychometric models when categorical and criterion‐referenced interpretations of growth are desired.  相似文献

The Teacher Behavior Inventory: validation of teacher behavior in an interactive lecture environment     

Siti Nurma Hanim Hadie  Asma’ Hassan  Saiful Bahri Talip  Muhamad Saiful Bahri Yusoff 《Teacher Development》2019,23(1):36-49

Students’ rating of teacher behaviors provides valuable information on teaching improvement and instructional quality. Unfortunately, there is a lack of new validated instruments for measuring teacher behaviors. The Teacher Behaviors Inventory is an old inventory that was initially developed to measure teaching behaviors as regards lecture-based instructions, which is effected through the use of low-inference items. The aim of this study was to assess its continued suitability in the present educational setting by examining its construct validity and internal consistency through the lens of one lecturer’s teaching behaviors, as rated by 527 students after six interactive lectures. The variables evaluated, as mentioned above, were achieved after an items removal process, which resulted in a 32-item version. Apart from being valid and reliable, this condensed version allows for immediate assessment of teaching behaviors after an instruction session as the rating procedure is now more straightforward and less time-consuming, and also enables a reduction in rating errors. Therefore, the 32-item format serves as a practical diagnostic feedback tool in the present educational arena, permitting a longitudinal teaching behavior assessment to enhance teachers’ professional development.  相似文献   

Spelling consistency affects reading in young Dutch readers with and without dyslexia     

Bosman AM  Vonk W  van Zwam M 《Annals of dyslexia》2006,56(2):271-300

Lexical-decision studies with experienced English and French readers have shown that visual-word identification is not only affected by pronunciation inconsistency of a word (i.e., multiple ways to pronounce a spelling body), but also by spelling inconsistency (i.e., multiple ways to spell a pronunciation rime). The aim of this study was to compare the reading behavior of young Dutch readers with dyslexia to the behavior of readers without dyslexia. All students participated in a lexical-decision task in which we presented pronunciation-consistent words and pseudowords. Half of the pronunciation-consistent stimuli were spelling consistent and the other half were spelling inconsistent. All three reader groups, that is, students with dyslexia, age-match students, and reading-match students, read spelling-consistent words faster than spelling-inconsistent words. Overall reading speed of students with dyslexia was similar to that of reading-match students, and was substantially slower than that of age-match students. The results suggest that reading in students with or without dyslexia is similarly affected by spelling inconsistency. Subtle qualitative differences emerged, however, with respect to pseudoword identification. The conclusion was that the findings were best interpreted in terms of a recurrent-feedback model.  相似文献

《德伯家的苔丝》与《圣经》的明分与暗合   总被引：1，自引：0，他引：1  

朱利娜 《涪陵师范学院学报》2007,23(2):152-156

小说中苔丝一直在寻求道德上的救赎,罪恶里的解脱,但苔丝的个性和社会的现实使悲剧成为必然;小说作者哈代本人曾经把整个故事看成是"众神的主宰对苔丝的戏弄";阿历克是造成苔丝痛苦的原因,却得到了道德上的保护,而苔丝真正爱过的安琪儿(英文Angel意为天使),却遗弃了苔丝,作者在作品中多处用重墨讽刺圣经中所宣扬的德福报应观.同时故事发展结构中却包含了"突转","发现","苦难"这三个贯穿在《圣经》福音书中的成分.于是一种复杂的双重关系将《苔丝》和《圣经》紧密的联系起来.  相似文献
