民营企业要建立契约制度     

王运浦  李彤 《绵阳师范学院学报》2005,24(6):13-15

民营企业建立契约制度，是历史发展的必然选择，是构建和谐社会的客观要求，是企业自身发展的需要。建立契约制度的前提，是建立信用体系，树立法制观念，重塑道德规范，细化规章制度。通过建立契约制度，可以实现生产要素的有效组合，使企业组织功能更好发挥，有利于建立有效的激励机制，有利于生产关系适合生产力的发展，有利于构建和谐社会。  相似文献

Triadic interaction in clinical task-based interviews with mathematics teachers     

Boris Koichu  Guershon Harel 《Educational Studies in Mathematics》2007,65(3):349-365

A clinical task-based interview can be seen as a situation where the interviewer–interviewee interaction on a task is regulated by a system of explicit and implicit norms, values, and rules. This paper describes how documenting and mapping triadic interaction among the interviewer, the interviewee, and the knowledge negotiated can be used to increase procedural replicability of the interview and accuracy of drawn conclusions about the interviewee’s thinking process. Excerpts from interviews with 25 inservice mathematics teachers working on a task to make up a problem whose solution requires division of two fractions are discussed. The excerpts illustrate the relationship between methodological decisions taken by the interviewer during the interview and the applicability of the interview output to the research questions. A divergent analysis of the interviews with these teachers, which spanned over two years and were conducted by four interviewers, is used to offer a framework for analyzing data collected in clinical task-based interviews.  相似文献   

Giving Education a Bad Name: Bookish Boys in Contemporary American School Stories     

David Aitchison 《Children‘s Literature in Education》2018,49(1):47-60

This article discusses contemporary American school stories that appear to advocate learning and literacy as a democratic good, but actually undermine democratic possibilities by teaching young readers to think of academic inquiry as a means to selfish, petty ends. Since “learning” and “literacy” are catchwords for educators dedicated to remedying neoliberal inequities, it is understandable why authors of school fiction such as Andrew Clements and Tommy Greenwald are celebrated by educators for foregrounding the exploits of bookish characters. Yet, as is shown, the narrative arcs in works such as Frindle by Clements and Charlie Joe Jackson’s Guide to Not Reading by Greenwald ultimately endorse the market consciousness, deregulation, and excessive individualism for which neoliberalism is known. Examining the ways in which these two novels intersect with ongoing debates over literacy standards, learning outcomes, and academic honesty, it is argued that the didactic-pedagogical imagination in contemporary American fiction for young people has a biased conception of student development and life preparedness, ideologically at odds with democratic curriculum provision.  相似文献   

Visualization of structured packing with laser induced fluorescence technique: Two-dimensional measurement of liquid concentration distribution     

刘伯潭  申言同  张会书  刘春江  唐忠利  袁希钢 《天津大学学报(英文版)》2016,22(5):466-472

A method of using laser induced fluorescence(LIF)technique was applied to two-dimensional measurement of the liquid concentration distribution in the 250Y structured packing sheet. The experimental structured packing sheet was made of perspex so that the laser could pass through it. The visualization of the distribution of the liquid concentration in the structured packing sheet was realized. The calibration of the thickness and liquid concentration was carried out firstly and the regression formula I=kcd was acquired, in which concentration c and the liquid film thickness d were both considered. Then the liquid feed of uniform tracer(rhodamine)concentration entered the perspex structured packing from the top under different spraying densities. The corresponding thickness of liquid film on the packing was calculated. Finally, tracer(rhodamine)with a high concentration was injected only at one fixed point of the structured packing under different spraying densities of the liquid. With the known liquid film thickness, the concentration distribution of the tracer can be calculated inside the structured packing sheet.  相似文献

Establishing a Center to Support Faculty Research     

Laura Goodwin  Elizabeth Kozleski  Rodney Muth  Lynn K. Rhodes  Kim Kennedy White 《Innovative Higher Education》2005,30(4):251-268

This article describes the establishment in fall 2002 of a School of Education Research Center designed to support faculty in increasing productivity and quality in research. Details are provided about center goals, services, staffing, space, resources, and logistics during the first year of operation. In addition, data are shared about faculty usage of the Center, the level of faculty satisfaction with center services in the first year, and initial increases in faculty productivity. The article concludes with plans for continued data collection to monitor the impact of the Center, a discussion of lessons learned at this point in the Center's development, and possibilities for the evolution of the Center. All authors are at the University of Colorado, Denver. Laura Goodwin, Ph.D., University of Colorado at Boulder, is Interim Associate Vice Chancellor for Faculty Affairs and continues to serve as a Faculty Research Associate. Elizabeth Kozleski, Ed.D., University of Northern Colorado, is the Associate Dean for Research in the School of Education. Lynn Rhodes, Ed.D., Indiana University, is the Dean of the School of Education. Rodney Muth, Ph.D., Claremont Graduate School, is a professor of Administrative Leadership and Policy Studies in the school and chaired the Research Center Advisory Board. Kim Kennedy White, M.A., University of Oregon, was the original School of Education Research Center Coordinator and was responsible for collecting most of the data included in this study.  相似文献
