高校领导干部要做到“八慎”     

哈斯 《职大学报》2012,(3):101-103

领导干部如何树立正确的权力观,是新形势下党的建设面临的新的挑战,是有效预防腐败的前提。领导干部要做到＂八慎＂,即慎权、慎欲、慎微、慎独、慎始、慎言、慎情、慎终。只有这样才能真正为民掌好权、用好权。  相似文献   

Inducing self-rotation of cells with natural and artificial melanin in a linearly polarized alternating current electric field

The phenomenon of self-rotation observed in naturally and artificially pigmented cells under an applied linearly polarized alternating current (non-rotating) electrical field has been investigated. The repeatable and controllable rotation speeds of the cells were quantified and their dependence on dielectrophoretic parameters such as frequency, voltage, and waveform was studied. Moreover, the rotation behavior of the pigmented cells with different melanin content was compared to quantify the correlation between self-rotation and the presence of melanin. Most importantly, macrophages, which did not originally rotate in the applied non-rotating electric field, began to exhibit self-rotation that was very similar to that of the pigmented cells, after ingesting foreign particles (e.g., synthetic melanin or latex beads). We envision the discovery presented in this paper will enable the development of a rapid, non-intrusive, and automated process to obtain the electrical conductivities and permittivities of cellular membrane and cytoplasm in the near future.  相似文献   

Physical activity in the lives of Hong Kong Chinese children     

Amy S. Ha  Doune Macdonald  Bonnie O. H. Pang 《Sport, Education and Society》2013,18(3):331-346

To understand the physical activity culture in the lives of Hong Kong Chinese children and their parents, 48 young people between the ages 9 and 16 and their parents, with different socio-economic backgrounds and geographical locations, were interviewed for this study. By applying Confucianism and postcolonialism, this study aimed to investigate the meaning of physical activity in the lives of Hong Kong children and their parents. The results showed that parents value physical activity as a factor which contributes to their children's well-being and provides balance to their life. There were differences though, in this attitude, for different age groups. Junior students (aged 9–12) expressed their interest in physical activities. However, older students (12 or above) in secondary school, think or are told that academic study is the most important aspect of their life and that physical activities are not a priority. When examining parents' and children's involvement in physical activity, the barriers to the parents' involvement in their children's physical activities included lack of time and a habitual sedentary lifestyle at home.  相似文献   

History of Mathematics in Korean Mathematics Textbooks: Implication for Using Ethnomathematics in Culturally Diverse School     

Mi-Kyung Ju  Jong-Eun Moon  Ryoon-Jin Song 《International Journal of Science and Mathematics Education》2016,14(7):1321-1338

From a multicultural perspective, this research investigated to what extent Korean mathematics textbooks use history of mathematics. The results show even though educational use of history presented in Korean mathematics textbooks may provide a rich outlook, it does not encourage a fundamental change in the educational practice of school mathematics that has traditionally been entrenched in the Eurocentric narrative of mathematics. This suggests that the mathematics textbooks were not organized effectively to promote students’ understanding of diversity. Based on the results, we discuss the implications for the development of mathematics textbook from multicultural perspectives.  相似文献   

Season of birth is related to child retention rates, achievement, and rate of diagnosis of specific LD   总被引：1，自引：0，他引：1  

Martin RP  Foels P  Clanton G  Moon K 《Journal of learning disabilities》2004,37(4):307-317

A sizable literature has demonstrated that the achievement of children in early elementary school is related to their season of birth: Those born in summer typically perform less well than those born in the fall. A small literature indicates that more children diagnosed with specific learning disabilities (SLD) are born in the summer. We have begun to explore the possibility that the same processes may account for both outcomes. In order to better understand these processes, the standardized achievement levels and rates of diagnosis of SLD for children born during each season were studied in one geographical area of the State of Georgia served by 28 school districts. Standardized achievement scores in reading, mathematics, and science were reliably lower for those born in the summer. Furthermore, there was a strong relationship between season of birth and the rate at which children received a diagnosis of SLD. Summer-born children were diagnosed with SLD at a higher rate than their peers. Four hypotheses for both the lower performance in the general school population and the greater rate of SLD diagnosis among these children are discussed.  相似文献

OCCUPATIONAL/CAREER INDECISION FOR ECONOMICALLY DISADVANTAGED HIGH SCHOOL STUDENTS OF HIGH INTELLECTUAL ABILITY: A MIXED‐METHODS COGNITIVE PROCESS MODEL          下载免费PDF全文

Jae Yup Jung  Marie Young 《Psychology in the schools》2017,54(7):718-735

A mixed‐methods design was employed to identify the cognitive processes that lead to occupational/career indecision for economically disadvantaged adolescents of high intellectual ability. In the first phase, interview data collected from 26 economically disadvantaged intellectually gifted Australian adolescents were analyzed using grounded theory to develop two alternative models of cognitive processes that lead to occupational/career indecision. In the second phase, these models were quantitatively tested and refined using structural equation modeling of survey data collected from 917 economically disadvantaged intellectually gifted Australian adolescents. The finally accepted model, identified using a competing models strategy, suggested that valuing the thoughts of family on general matters is positively predictive of a desire to live up to one's potential and the experience of amotivation about the occupational decision. In turn, occupational amotivation appears to be positively associated with occupational indecision, but negatively associated with multipotentiality and a desire to fulfill one's potential.  相似文献   

Cultivating divergent thinking in mathematics through an open-ended approach     

Oh Nam Kwon  Jee Hyun Park  Jung Sook Park 《Asia Pacific Education Review》2006,7(1):51-61

The purpose of this study was to develop a program to help cultivate divergent thinking in mathematics based on open-ended problems and to investigate its effect. The participants were 398 seventh grade students attending middle schools in Seoul. A method of pre- and post-testing was used to measure mainly divergent thinking skills through open-ended problems. The results indicated that the treatment group students performed better than the comparison students overall on each component of divergent thinking skills, which includes fluency, flexibility, and originality. The developed program can be a useful resource for teachers to use in enhancing their students’ creative thinking skills. An open-ended approach in teaching mathematics suggested in this paper may provide a possible arena for exploring the prospects and possibilities of improving mathematical creativity.  相似文献   

论现代公关言语运用准则     

哈森 《内蒙古师范大学学报(哲学社会科学版)》1996,(3)

本文结合实例论述了现代公关言语及其运用准则①。＂言语＂，不同于＂语言＂，＂公关语言＂实为＂公关言语＂；现代公关言语交际和一般言语交际有密切联系，现代公关言语运用准则要接受一般言语交际原则的制约，前者是后者的具体化，也是对后者的补充；现代公关言语运用准则也适用于非公关言语交际，但二者有区别。  相似文献
