社会支持与幼儿园教师留职意向的关系:组织公平感和工作投入的序列中介效应

社会支持是幼儿园教师应对职业压力的重要心理资源。为探讨幼儿园教师社会支持与留职意向的关系以及组织公平感与工作投入在二者关系中的作用,本研究选取了宁夏回族自治区1693名幼儿园教师为研究对象,采用社会支持量表、留职意向量表、组织公平感量表和工作投入量表进行测量。结果发现幼儿园教师的留职意向总体较好;社会支持和留职意向在教龄、园所性质、园所地域上存在显著差异,其中16年及以上教龄、公立幼儿园、村镇幼儿园教师的社会支持较高,留职意向也显著较高;社会支持、组织公平感、工作投入和留职意向两两显著正相关;社会支持对留职意向有显著的正向预测作用;组织公平感和工作投入在社会支持和留职意向之间起中介作用。具体而言,社会支持通过三条路径影响幼儿园教师留职意向,一是组织公平感的单独中介作用,二是工作投入的单独中介作用,三是组织公平感和工作投入的序列中介作用。为提高幼儿园教师的留职意向,应通过学前教育立法强化制度供给,切实改善幼儿园教师的社会地位与薪资待遇;通过文化和制度建设营造公平、公开、透明的组织环境;通过在职培训支持教师加强自身心理建设,引导教师客观看待问题,形成现实合理的期待,发展积极乐观的态度,主动增加工作投入。     

职业教育改革背景下学分银行制度建设的理念、组织体系与效果研究

随着中国教育素质不断提高,职业教育保持强劲的持久力,对国家经济、社会发展作出了巨大贡献,但是也面临一种"高不成低不就"的局面.为此,从学分银行制度内涵和要素出发,采用从理念基础到实践应用的探索规律,分析国内外学分银行制度建设现状,提出构建以终身教育和学习型社会理念为学分银行持续发展的支撑基础,以建立知识密集型服务企业组织体系为学分银行内部运行的重要保障,最终实现职业教育人才市场供需为学分银行的核心效益的建设路径,旨在为探索职业教育学分银行制度建设的持续性、有序性和有效性发展提供思路.     

超薄CRT的S校正

为了对大偏转角下的超薄CRT图像S畸变进行校正,针对匀强磁场和六极场以及理想纯平和实际曲率荧光屏的情况,分别推导了进行S校正以实现匀速屏幕扫描所需的扫描电流理论形式.继而采用高阶正弦信号来逼近这一理论电流波形,以便于电路实现.优化计算后的扫描电流可以在90°直到140°的偏转角范围内以足够精度逼近理论值,谐波阶数随着角度增大而增加直至四阶.提出了一种梯形电路来实现这一方法,模拟和实验结果证实了该方法对校正S畸变的效果.     

Finite element modeling for analysis of cracked cylindrical pipes

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.

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

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.     

中国菊科菊苣族一些属的分类研究

 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.     

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

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.

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

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.
