服务业就业比重与失业率的关系研究   总被引：7，自引：0，他引：7  

程永宏 《中国软科学》2005,(2):46-56

面对当前中国沉重的就业压力,流行的观点认为,发展服务业能够扩大就业,降低失业率。本文利用世界银行相关经验数据,对服务业就业比重与就业总量、失业率等方面的关系进行计量经济学分析,发现了几个重要关系：就业总量与服务业就业比重存在显著正相关;劳动力总供给和女性劳动参与率与服务业就业比重也存在显著正相关。这一发现有力地解释了普遍存在于市场经济国家的一种现象：服务业就业比重的上升尽管创造了新的就业机会,但失业率却没有因此而下降。  相似文献

Peer-Based Supplemental Instruction in STEM: Differences in Effectiveness Across Transfer and Nontransfer Undergraduates     

Rabi A. Musah  Michael Ford 《Journal of research on educational effectiveness》2017,10(3):596-618

Although there is a large body of research on the effectiveness of supplemental instruction for college undergraduates, very little of it has focused on transfer students, who often confront additional sources of stress and historically perform more poorly than their native student counterparts. In this study, we investigated the effectiveness of a peer-based supplemental instructional program in general and organic chemistry at a large state university over a six-year period, while considering differences across transfer and nontransfer students. The results suggest that the supplemental instruction improved outcomes overall but that nontransfer students benefit to a greater degree than transfer students, in the form of higher grades and pass rates, from attending supplemental instruction. The results suggest that peer-based supplemental instruction is a useful method to improve undergraduate student performance in chemistry, but more research is needed on ways to enhance the effectiveness of interventions in improving the performance of transfer undergraduate students in STEM fields.  相似文献

论练琴方法     

马兰 《海南师范大学学报(社会科学版)》2003,16(1):114-116

培养科学的，良好的练琴习惯是学生学习钢琴中应放在首位的问题，某一次练琴或某几次练琴的好坏，仅仅涉及到一次或几次的练习效果，而某种习惯的好坏则会影响整个学习进程，甚至关系到学习效果。因此，培养良好的读谱习惯，坚持科学的练琴方法是提高练琴效率的关键。  相似文献   

A reexamination of the effect of big-time football and basketball success on graduation rates and alumni giving rates   总被引：1，自引：0，他引：1  

Irvin B. Tucker   《Economics of Education Review》2004,23(6):655

To determine the impact on the academic mission, the models in this study test whether there is statistical evidence that student graduation rates or alumni giving rates are influenced by pigskin or hoop success for major universities after adjustment for key academic variables. Using a sample of big-time sports universities and models comparable to other research, the evidence presented in this article indicates that having a highly successful football team has a positive impact on both the overall graduation rate and the alumni giving rate. In contrast, a successful basketball team has no significant effect on either of these key measures of academic success.  相似文献   

A tracer study of Lebanese upper secondary school students   总被引：1，自引：0，他引：1  

Barend Vlaardingerbroek  Kamel Dallal  George Rizkallah  Jihan Rabah 《International Journal of Educational Development》2007

This paper presents data arising from a tracer study of 90 terminating Beirut upper secondary school students. Nearly all the students intended to transit to university, about half of them to science and technology programmes, and subsequently did so. Median anticipated earnings upon graduation were realistic, but a lack of information or guidance about higher education and career options was noted by a considerable proportion. The results of the study are discussed with reference to the as yet poorly elucidated dynamics of schooling with regard to attrition and transition to higher education and employment in Lebanon.  相似文献

Comparing active game-playing scores and academic performances of elementary school students     

Serhat Bahadır Kert  Meryem Köşkeroğlu Büyükimdat  Ahmet Uzun 《Education 3-13》2017,45(5):532-542

In the educational sciences, many discussions on the use of computer games occur. Most of the scientists believe that traditional computer games are time-consuming software and that game-playing activities negatively affect students’ academic performance. In this study, the accuracy of this general opinion was examined by focusing on the real game-playing scores of an elementary school students in Turkey. First, researchers selected a single-player strategy game. Second, the selected game was given to 105 fifth-grade students, who had not played it before, so that they could play it over a 30-minute period. The most successful student of the group finished the 23rd level of the game and collected 8152 points in total. In order to investigate the correlation between strategy game performance and academic performance, researchers derived the students’ average exam scores for six different courses (mathematics, physical science, science and technology, visual arts, music, and social sciences) from official documents. At the end of the study, it was found that participants’ mathematical or physical science skills were positively correlated with game success; however, a negative relationship was not exists between an individual's computer game success and academic performance.  相似文献
