国企改革与医疗保险制度可持续发展的思考

随着市场经济的进一步深化和国有企业改革的推进,必将有一部分人员提前退出工作岗位,这部分人员融入基本医疗保险,将会对基本医疗保险制度的稳健运行和可持续发展产生影响。妥善解决好这部分职工的医疗保险问题,对我市构建和谐社会和实现率先发展都有积极的意义。     

Stability and electronic spectra of C76N2 isomers

INTRODUCTION The synthesis and characterization of het-erofullerenes are very challengeable research topics because of application in superconductivity, photo-electronics, organic magnetism and even nanotubes. Pradeep et al.(1991) studied the interaction between nitrogen and fullerenes and obtained nitrogen deriva-tives of C60 and C70 such as C59N2, C59N4, C59N6 and C70N2 by contact-arc vaporization of graphite in a partial N2 or NH3 atmosphere. Yu et al.(1995) syn-thesized carbon n…

Yimu San improves obstetric ability of pregnant mice by increasing serum oxytocin levels and connexin 43 expression in uterine smooth muscle

Prolonged farrowing remains one of the critical challenges in intensive pig farming. This study aims to explore the effects and mechanism of Yimu San (YMS), a Chinese veterinary medicine micro mist, on delivery ability with mouse models. Thirty-two pregnant mice were randomly divided into a control group and low-YMS, med-YMS, and high-YMS groups. The labor process time and stillbirth rate were recorded, the levels of serum oxytocin and prostaglandin E₂ (PGE₂) were measured with enzyme-linked immunosorbent assay (ELISA). Contractility measurements of the isolated uterus and the expression of connexin 43 (Cx43) in uterine smooth muscle were evaluated. The results showed that compared with the control group, the birth process time and stillbirth rate in the med-YMS and high-YMS groups were remarkably lower. The in vitro uterine contractions, levels of oxytocin, PGE₂, and Cx43 in the med-YMS and high-YMS groups were significantly higher than those in the control group. The differences of the above measurements between the low-YMS group and the control group were not obvious. It can be speculated that YMS could significantly promote labor in pregnant mice by enhancing the levels of oxytocin, Cx43, and PGE₂.

Teachers’ beliefs of behaviors,learning, and teaching related to minority students: a comparison of Han and Mongolian Chinese teachers

Teachers from mainstream and minority backgrounds teaching in the same school contexts presumably hold different beliefs of learning and teaching about minority students due to their unique prior life and ethnic experiences. Teachers in similar school environments are also assumed to share beliefs of teaching and learning about their students because of the influences of their similar school contexts despite their different prior life and ethnic experiences. This study examines the two contentious assumptions by surveying the beliefs of behavior, learning, and teaching that the mainstream Han and minority Mongolian Chinese teachers in the same school contexts hold about their Mongolian Chinese students. It found that the two groups agreed that teachers’ inadequate planning and management were the major sources of their students’ behavior problems while students’ home backgrounds, abilities, and efforts explained their learning failure or success. Both believed that students’ emotional and social problems were more important than their learning problems for them to attend to, and their expertise in helping students develop self-worth was more important than their expertise in curriculum and pedagogy. Both preferred to vary teaching standards, content, and methods to accommodate students’ differences and offer opportunities for students to discover things themselves.
