职业教育的本质属性与发展模式选择

进入新世纪，职业教育确立了以服务为宗旨、以就业为导向的发展思路，提出了职业教育办学思想要实现三个转变：一是从计划培养向市场驱动转变；二是从政府直接管理向宏观引导转变；三是从专业学科为本位向职业岗位和就业为本位转变。其最终目的是要求职业教育建立一条有别于普通教育的发展模式。

略论李绅诗歌中的儒道释思想

李绅的诗歌体现了唐代儒道释三家并兴对文人士子的价值取向所产生的影响,其中,儒家追求功名业绩的人生理想和价值观念在李绅一生中占主导地位,远远超出道佛二家对他的影响。积极入世、求为世用的儒家思想在他诗中主要表现为忠君、爱民和仕宦情结,李诗中偶尔流露出的退隐思想、明哲保身之道则折射出道家思想对他的影响,当他对现实感到失望甚至绝望时,也会把目光更多地转向佛教教义,从中寻求解脱,希望得到救赎。     

Gender, BMI, values, and learning in physical education: A study on Chinese middle schoolers

Students' different perceptions of task values influence their learning experience and achievement in physical education. Framed using the subjective task value construct, this study was conducted to determine the extent to which male and female Chinese middle schoolers with different body sizes differed in their perception of the task values. A second goal of the study was to identify the extent to which the task values along with gender and body size predicted students' performance on knowledge and physical skill tests. Data from a random sample of students (N = 860) from eight Chinese middle schools revealed that the boys appreciated intrinsic (p = .001) and utility values (p = 02); both boys and girls, however, equally appreciated the attainment value (p = .73). The boys performed better in physical skill tests than the girls (p = .001), whereas the girls scored higher in knowledge tests than the boys (p = .04). Regression analyses revealed that gender is the only predictor for performance on both knowledge and skill tests. Utility value and body size were predictors for skill, not for knowledge. These findings indicate that Chinese middle school boys and girls differed in valuing and achieving in physical education. The findings imply that Chinese boys need to strengthen cognitive learning and girls need to strengthen psychomotor skill development in physical education.     

论秦朝统一思想与思想统一的二律背反

公元前221年秦吞并关东六国,建立了大一统的国家。为了加强统治,秦统治者强调用法家治国,以思想上的统一巩固政治上的统一。然而,法家思想的局限和统一手段的不合理造成了秦朝社会思想文化领域内的冲突,这一冲突以法家思想和非法家思想,主要是儒家思想为主要内容,历秦朝社会之始终而存在,成为秦朝短命而亡的一个重要因素。

1016名学生PTC尝味能力基因频率的调查

目的:了解味盲基因频率和基因型频率在不同群体中的分布,从而为人种学及人类群体遗传学提供基本数据,并用于研究某些疾病。方法:本文是运用阈值法研究满、汉、回三民族人的尝味能力,并计算了味盲者和尝味者的基因频率。结果:三民族味盲基因频率分别为:满族:0.4588.汉族:0.2845 回族:0.4431。结论:满、汉、回三民族人对PTC尝味能力在统计学上存在显著差异,不同的民族有不同的基因库。     

论道德需要及其培养

一、道德需要培养的必要性长期以来,我国道德教育注重从应然层面强调人的道德责任,如人“应该”讲道德,“应该”无条件地为成就道德而舍己、牺牲、奉献、利他,这种牺牲是人的义务。但问题是,人何以需要道德?如何才能使人具有道德?道德与个人幸福是否有关?如果完全无关,人怎么可     

Allograftic bone marrow-derived mesenchymal stem cells transplanted into heart infarcted model of rabbit to renovate infarcted heart

Objective: To investigate the directed transplantation of allograftic bone marrow-derived mesenchymal stem cells (MSCs) in myocardial infarcted (MI) model rabbits. Materials and Methods: Rabbits were divided into 3 groups, heart infarcted model with MSCs transplanted treatment (MSCs group, n=12), heart infarcted model with PBS injection (control group, n=20), sham operation with PBS injection (sham group, n=l 7). MSCs labelled by BrdUrd were injected into the MI area of the MSCs group. The same volume of PBS was injected into the MI area of the control group and sham group. The mortality, LVIDd, LVIDs and LVEF Of the two groups were compared 4 weeks later. Tropomyosin inhibitory component (Tn I) and BrdUrd immunohistochemistry identified the engrafted cells 4 weeks after transplantation. Result: The mortality of the MSCs group was 16.7% (2/12), and remarkably lower than the control group's mortality [35% (7/20) (P＜0.05)].Among the animals that survived for 4 weeks, the LVIDd and LVIDs of the MSCs group after operation were 1.17±0.21 cm and 0.74±0.13 cm, and remarkably lower than those of the model group, which were 1.64±0.14 cm and 1.19±0.12 cm (P＜0.05); the LVEF of the MSCs group after operation was 63±6%, and remarkably higher than that of the model group,which was 53±6% (P＜0.05). Among the 10 cases of animals that survived for 4 weeks in the MSCs group, in 8 cases (80%),the transplanted cells survived in the non MI, MI region and its periphery, and even farther away; part of them differentiated into cardiomyocytes; in 7 cases (70%), the transplanted cells participated in the formation of blood vessel tissue in the MI region. Conclusion: Transplanted allograftic MSCs can survive and differentiate into cardiomyocytes, form the blood vessels in the MI region. MSCs transplantation could improve the heart function after MI.
