从不同类型幼儿园经费收支状况看城市学前教育的发展     

张亚军  陈群 《学前教育研究》2011,(1)

不同类型幼儿园的经费收支状况表明不同类型幼儿园的办园成本不同,其中自收自支型公办园与差额拨款型公办园都因政府财政投入不足而运转困难,资金十分紧张;小区配套民办幼儿园的成本开支最大,在良性运转模式下需较高收费方能维持。生存的压力迫使前两种类型的公办园不得不在实际运作中扩大班额,举办举趣班,压缩教师工资、福利及公用开支等;而对利润的追求与对尽快回收成本的迫切希望也促使民办园在实际运作中扩大招生,尽力压缩教师待遇与公用开支。可以说在政府投入与扶持十分匮乏的情况下,无论公办园还是民办园都面临着生存的困难与无奈。为改变这种现状,政府应积极承担起发展学前教育的职责,一方面全额投入、全力办好城市公办园,使之能切实发挥示范与引领的作用,另一方面积极扶持和引导民办园良性运作和发展,将民办园纳入统一的管理体系,在对幼儿园评级分类、财政性经费投入与分配等方面使之享受与公办园同等的待遇。虽然目前城市一般已基本普及学前三年教育,但是以家长的较高经济负担为代价的,未能充分体现学前教育的普惠性质与公益性,因此未来城市学前教育的发展仍应致力于优先保证适龄幼儿学前教育的基本普及,这需要政府有相应的政策和经费保证,同时合理利用社会力量,根据居民...  相似文献   

对学前教育史研究的三种认识及其学术价值   总被引：1，自引：0，他引：1  

蒋雅俊 《学前教育研究》2011,(6)

学前教育史是学前教育学学科建设的重要组成部分,是学前教育理论发展的重要资源之一.学前教育史不仅包含对学前教育历史事件的记录,更包含对学前教育历史事件的理解与叙述,这使学前教育史必然是不断被研究者重新书写的思想史与当代史,开展学前教育史研究必然是一项富有创造性的工作.它不仅能够帮助我们深刻地理解过去,而且能够帮助我们深刻地理解现在、预见未来,更好地认识学前教育发展的客观规律,更好地把握学前教育发展的时机.  相似文献

以质粒pSC101为载体,用鸟枪法将短小芽孢杆菌A3染色体的β—内酰胺酶基因,克隆至大肠杆菌HB101。经质粒检测及酶切电泳分析证明,克隆的β—内酰胺酶基因位于2.6kb的EcoRI片段上,将此片段连接到质粒PAL32转化枯草杆菌,亦能表达并向胞外分泌β—内酰胺酶。  相似文献   

Investigation on apoptosis of neuronal cells induced by Amyloid beta-Protein     

罗本燕  徐增斌  陈智  陈峰  唐敏 《浙江大学学报(A卷英文版)》2004,5(8):989-994

Objective: To construct a PC12 cell strain with neuronal differentiation, and observe the apoptosis and pro-liferation activity effects induced these cells by Amyloid beta-Protein (Aβ-43). Methods: 1) PC12 cells in logarithmicgrowth phase were subcultured for 24 h. After the culture fluid was changed, the cells were treated with Rat-β-NGF andcultured for 9 days. 2) Neuronal differentiation of PC12 cells in logarithmic growth phase were divided into four groups:control group (0), experimental group (1), experimental group (2) and experimental group (3). The concentrations of Aβ inthe four groups were 0 μmol/L, 1.25 μ mol/L, 2.5 μ mol/L and 5 μmol/L, respectively. The cells were harvested at 24, 48 and72 h later and stained with AnnexinV-FITC/PI after centrifugation and washing. Then flow cytometry was conducted toexamine the apoptosis percentage. 3) NGF-induced PC12 cells were selected and Aβ with different concentrations wasadded. The final concentrations of Aβ were 0 μmol/L, 1.25 μmol/L, 2.5 μmol/L and 5 μ mol/L, respectively. After the cellswere incubated in an atmosphere of 5% CO2 at 37 ℃ in an incubator for 72 h, the OD values were examined. Results: 1)Neuronal differentiated PC 12 cell lines were successfully established. 2) Flow cytometric examination indicated that Aβ(1.25, 2.5, and 5.0 μmol/L) could effectively induce apoptosis of neuronal-differented cells at the 24 h, 48 h and 72 h timepoints. 3) Aβ (0-5.00 μ mol/L) had no obvious effect on proliferation or restraining of the neuronal differentiation of thePC 12 cells after a 72 h interacting process. Conclusion: This investigation revealed successful neuronal differentiation of thePC12 cell strain. The induction of apoptosis of the neurocytes by various concentrations of Aβ was observed and the in-fluence of Aβ on induced proliferation of PC 12 cells by Rat-β-NGF was revealed. This study -05 provide basis for futureresearch on the molecular cure of AD and interdiction of AD evolution.  相似文献   

Clinical analysis of minimally invasive McKeown esophagectomy in a single center by a single medical group     

Zi-yi Zhu  Xu Yong  Rao-jun Luo  Yun-zhen Wang 《Journal of Zhejiang University. Science. B》2018,19(9):718-725

Objective: McKeown esophagectomy followed by cervical and abdominal procedures has been commonly used for invasive esophageal carcinoma. This minimally-invasive operative procedure in the lateral prone position has been considered to be the most appropriate method. We describe our experiences in minimally invasive McKeown esophagectomy (MIME) for esophageal cancer. Methods: Between March 2016 and February 2018, a total of 82 patients underwent MIME by a single group in our department (a single center). All procedure, operation, oncology, and complication data were reviewed. Results: All MIME procedures were completed successfully, with no conversions to open surgery. The median operative time was 260 min, and median blood loss was 100 ml. The average number of total harvested lymph nodes was 20.1 in the chest and 13.5 in the abdomen. There were no deaths within 30 postoperative days. Twenty cases (24.4%) developed postoperative complications, including anastomotic leak in 4 (4.9%), single lateral recurrent nerve palsy in 4 (4.9%), bilateral recurrent nerve palsy in 1 (1.2%), pulmonary problems in 3 (3.7%), chyle leak in 1 (1.2%), and other complications in 7 (including pleural effusions in 4, incomplete ileus in 2, and neck incision infection in 1; 8.54%). Average postoperative hospitalization time was 12 d. Blood loss, operation time, morbidity rate, and the number of harvested lymph nodes were analyzed by evaluating learning curves in different periods. Significant differences were found in operative time (P=0.006), postoperative hospitalization days (P=0.015), total harvested lymph nodes (P=0.003), harvested thoracic lymph nodes (P=0.006), and harvested abdominal lymph nodes (P=0.022) among different periods. Conclusions: Surgical outcomes following MIME for esophageal cancer are safe and acceptable. The MIME procedure for stages I and II could be performed proficiently and reached an experience plateau after approximately 25 cases.  相似文献
