中国菊科鸦葱属植物分类研究     

石铸 《中国科学院研究生院学报》1987,25(1):39-49

 About 22 species of the genus Scorzonera L. are so far known to occur in China. Among them, S. pamirica Shih is described as new and 3 species, S. tau-sahyz Lipsch. et Bosse, S. pubescens DC. and S. transiliensis M. Pop., are new records to China.  Four names in the literature are reduced to synonyms,and some wrong identications in Chinese botanical literature are pointed out in this work.  Some species with considerable variation in morphology, such as, S. pseudodivaricata Lipsch. and S. sinensis Lipsch. ex Krasch., are also discussed here.  相似文献

Modeling Randomness in Judging Rating Scales with a Random-Effects Rating Scale Model     

Wen-Chung Wang  Mark Wilson  Ching-Lin Shih 《Journal of Educational Measurement》2006,43(4):335-353

This study presents the random-effects rating scale model (RE-RSM) which takes into account randomness in the thresholds over persons by treating them as random-effects and adding a random variable for each threshold in the rating scale model (RSM) ( Andrich, 1978 ). The RE-RSM turns out to be a special case of the multidimensional random coefficients multinomial logit model (MRCMLM) ( Adams, Wilson, & Wang, 1997 ) so that the estimation procedures for the MRCMLM can be directly applied. The results of the simulation indicated that when the data were generated from the RSM, using the RSM and the RE-RSM to fit the data made little difference: both resulting in accurate parameter recovery. When the data were generated from the RE-RSM, using the RE-RSM to fit the data resulted in unbiased estimates, whereas using the RSM resulted in biased estimates, large fit statistics for the thresholds, and inflated test reliability. An empirical example of 10 items with four-point rating scales was illustrated in which four models were compared: the RSM, the RE-RSM, the partial credit model ( Masters, 1982 ), and the constrained random-effects partial credit model. In this real data set, the need for a random-effects formulation becomes clear.  相似文献

How Well Performance in Curriculum-based Tests Predicts that in Life-based Tests: A Study of 12th-grade Students Learning Chinese Language     

Kay Cheng Soh  Shih Yar Chia 《Asia Pacific Journal of Education》1997,17(2):77-84

A sample of 209 secondary (12th grade) students were tested for their knowledge of Chinese characters, words, and idioms as specified in a Chinese Language syllabus. The students also took comprehension tests in the form of cloze tests based on passages selected from Chinese newspapers and literary works, covering occupations, social events, sports, leisure pursuits and international news. Although performance in curriculum-based tests was satisfactory, the students were found to have difficulty comprehending life-based reading materials. Probable causes for the lack of consistency between performances in the tests using different reading materials are discussed.  相似文献

China’s popular nationalism on the internet. Report on the 2005 anti‐Japan network struggles 1     

Shih‐Diing LIU 《Inter-Asia Cultural Studies》2013,14(1):144-155

Abstract

In April 2005, waves of anti‐Japan protest swept China and South Korea. In China, hundreds of thousands of people took to the streets in more than 40 cities to protest against Japan over its irresponsible attitude toward the history of colonial rule and war crimes of 60 years ago. Despite the protest having a strong ground and its action being generally non‐violent and peaceful, it was then severely condemned by many Western critics and media as chauvinistic and irrational, and as being manipulated by the Chinese government to legitimize its rule. Against such a notion, this essay attempts to work with China’s ‘popular nationalism’ (renmin minzu zhuyi), and considers its space as an autonomous political domain that is independent of the state nationalism. The ‘cyber‐nationalism’ (wanglu minzu zhuyi), this paper argues, not only challenges the state monopoly over domestic nationalist discursive production, but also opens up new possibilities for performing common people’s ‘public discursive right’ (gonggong huayu quanli). Far from being a homogeneous unity, the online campaign is characterized by free exchange of information and lively debate over the boycott strategy.  相似文献   

Resilience strategies for new teachers in high-needs areas   总被引：1，自引：0，他引：1  

Antonio J. Castro  John Kelly  Minyi Shih 《Teaching and Teacher Education》2010

This qualitative study investigates strategies of resilience exhibited by fifteen novice teachers employed in high-needs areas, such as in urban and rural contexts and in special education. Findings indicated that teachers utilised a variety of strategies, including help-seeking, problem-solving, managing difficult relationships, and seeking rejuvenation/renewal. These strategies assisted beginning teachers in building additional resources and support; however, the burden for success and securing resources fell on teachers themselves. Furthermore, the researchers recognised that resilient teachers demonstrated agency in the process of overcoming adversity. Implications for future practice and research are discussed.  相似文献
