ABSTRACT

Meta-analytic evidence supports that exercise has benefits for short-term memory (STM) and long-term memory (LTM). However, only three studies with children have tested the differential effects of exercise on STM and LTM. The purpose of this study was to examine the effects of an aerobic fitness test on STM and LTM and to consider the moderating effects of grade level. Children (7–13 years of age) were randomly assigned to either perform an aerobic fitness test before (exercise prior) or after (exercise post) performing the Rey Auditory Verbal Learning Test (RAVLT) to assess memory. Memory was tested again after approximately 24 hours. There were significant differences in memory performance as a function of grade with 4^th and 6^th graders consistently outperforming 2^nd graders. For learning, Day 1 Retention, 24-hr recall, and Day 2 Retention, the exercise prior group performed better than the exercise post group. It is concluded that an aerobic fitness test performed prior to a declarative memory test benefits LTM as compared to when the aerobic fitness test is performed after the memory test.  相似文献   

Finite element modeling for analysis of cracked cylindrical pipes     

SUNG Wen-pei GO Cheer-germ SHIH Ming-hsiang 《浙江大学学报(A卷英文版)》2007,8(9):1373-1379

The characteristic properties of shell element with similar shapes are used to generate a so-called super element for the analysis of the crack problems for cylindrical pressure vessels. The formulation is processed by matrix condensation without the involvement of special treatment. This method can deal with various singularity problems and it also presents excellent results to crack problems for cylindrical shell. Especially,the knowledge of the kind of singular order is not necessary in super element generation; it is very economical in terms of computer memory and programming. This method also exhibits versatility to solve the problem of kinked crack at cylindrical shell.  相似文献

Factors related to Taiwanese adolescents' academic procrastination,time management,and perfectionism     

Shu-Shen Shih 《The Journal of educational research》2017,110(4):415-424

There is a shortage of studies that explore adolescents' academic procrastination. The author hence attempted to examine the mechanisms determining Taiwanese adolescent students' perfectionistic tendencies, time management, and academic procrastination. A total of 405 eighth-grade Taiwanese students completed a self-reported survey assessing their perceptions of classroom structure, parental expectations and criticism, perfectionistic tendencies, time management, and academic procrastination. Findings of regression analyses indicated that parental expectations and criticism were the key predictors of students' adaptive and maladaptive perfectionism. Students' perceptions of classroom structure also positively predicted their adaptive perfectionism. Moreover, results of hierarchical regressions suggested that perceived classroom structure, parental expectations and criticism, as well as adaptive perfectionism all emerged as predictors of time management. With regard to procrastination on homework and examination preparation, parental expectations and adaptive perfectionism were negative predictors, whereas parental criticism and maladaptive perfectionism were positive predictors. Also, time management negatively predicted academic procrastination.  相似文献

石铸 《中国科学院研究生院学报》1993,31(5):432-450

 The Present paper is a preliminary result of study on three genera, Dubyaea, Syncalathium and Soroseris of the tribe Lactuceae (Compositae) in China. The genus Dubyaea in China so far known consists of 14 species,  of which six are described here as new:  D. pteroponda Shih,  D.  lanceolate Shih,  D. muliensis Shih, D. panduriformis Shih, D. cymiformis Shih and D. jinyangensis Shih. In addition, one new combination, i.e.D. bhotanica (Hutch.) Shih, is made.      There are six species in the genus Syncalathium in Chinese flora, of which one species is described here as new. This is S. orbiculariforme Shih. A new combina- tion, S. pilosum (Hand.-Mazz.) Shih, is made in the paper.      The genus Soroseris comprises nine species, of which three are described here as new, S. teres Shih, S. chrysocephala Shih and S. qinghaiensis Shih. Three new combinations, i.e.S. trichocarpa (Franch.) Shih, S. hirsuta (Anth.) Shih, and S.erysimoides (Hand.-Mazz.) Shih are made in the present paper.  相似文献   

An Assessment of Environmental Literacy and Analysis of Predictors of Responsible Environmental Behaviour Held by Secondary Teachers in the Hualien Area of Taiwan     

Shih‐Jang Hsu  Robert E. Roth 《Environmental Education Research》1998,4(3):229-249

This study assessed teachers' environmental literacy and analysed predictors of teachers' responsible environmental behaviour (REB). A nine page instrument was administered by mailed questionnaire to 300 randomly selected secondary teachers in the Hualien area of Taiwan with a 52.3% effective response rate. As a result of stepwise multiple regression analyses, the most parsimonious set of predictors of REB for all teachers included: perceived knowledge of environmental action strategies (KNOW), intention to act, area of residence and perceived skill in using environmental action strategies (SKILL, total r² = 0.3867). For urban teachers, the most parsimonious set of predictors included: intention to act, SKILL, major sources of environmental information and membership in environmental organisations (total r² = 0.4711). For rural teachers, the most parsimonious set of predictors included: KNOW, intention to act and perceived knowledge of environmental problems and issues (total r² = 0.3200). Implications for programme development and instructional practice are presented. Recommendations for further research are also provided.  相似文献

Significant life experiences affect environmental action: a confirmation study in eastern Taiwan     

Shih‐Jang Hsu 《Environmental Education Research》2009,15(4):497-517

Two field studies form the basis of this article. The major purposes of Study 1 were to examine significant life experiences affecting the cultivation of environmental activists in eastern Taiwan, and to reconstruct the life paths followed by those active people who engaged in effective environmental action. 40 usable autobiographical memories were collected and content‐analysed to derive 17 significant life experiences. Based on the 17 accounts, a quantitative questionnaire of 24 items on significant life experiences variables was developed for Study 2. Four hundred and thirty valid questionnaires were analysed. Eighty two respondents with a high level of environmental action were determined to be environmental activists, and 153 with a low level of environmental action were determined to be people apathetic towards environmental protection. It was found that the significant life experiences identified in Study 1 could effectively distinguish environmentally committed people from those apathetic to environmental protection. Study 2 also found that 54.6% of the variances in environmental actions could be explained by the significant life experiences.  相似文献   

Comparing response rates in e-mail and paper surveys: A meta-analysis     

Tse-Hua Shih  Xitao Fan 《Educational Research Review》2009,4(1):26-40

This meta-analysis examined 35 study results within last 10 years that directly compared the response rates of e-mail versus mail surveys. Individual studies reported inconsistent findings concerning the response rate difference between e-mail and mail surveys, but e-mail surveys generally have lower response rate (about 20% lower on the average) than mail surveys. Two study features (population type and follow-up reminders) could account for some variation in the e-mail and mail survey response rate differences across the studies. For the studies involving college populations, the response rate difference between e-mail and mail surveys was much smaller, or even negligible, suggesting that e-mail survey is reasonably comparable with mail survey for college populations. The finding about follow-up reminder as a statistically significant study feature turns out to be somewhat an anomaly. Other study features (i.e., article type, random assignment of survey respondents into e-mail and mail survey modes, and use of incentives) did not prove to be statistically useful in accounting for the variation of response rate differences between mail and e-mail surveys. The findings here suggest that, in this age of internet technology, mail survey is still superior to e-mail survey in terms of obtaining higher response rate.  相似文献
