论农村土地政策在农村人力资源开发中的作用

在对我国丰富的农村人力资源的开发过程中 ,农村土地政策始终是一个关键因素。如果党和政府制定的农村土地政策符合农村人事矛盾的发展要求 ,它就会积极促进农村人力资源的开发与利用 ;反之 ,则会阻碍甚至破坏农村人力资源的正常开发与利用。在 2 1世纪我们必须贯彻正确的农村土地政策 ,保证农村人力资源的有效开发 ,积极促进农村社会经济的健康发展。     

浅谈计算机网络在教学中的应用

随着21世纪信息化社会的到来,传统的教学模式已日益显得不适应社会的需求,而以意义建构及伙伴群体论为基础的新的教学模式,采用了现代化的网络教学手段,以学生自主学习为主,通过各种学习活动且配合适当的合作讨论及教师辅导,使学生在学习知识和技能的过程中培养能力。     

Teacher expectations in a university setting: the perspectives of teachers

ABSTRACT

This study was designed to investigate the bases of teacher expectations in higher education. The first author interviewed 20 university teachers from an English-as-a-foreign-language course, exploring their expectations for the first-year undergraduates in their classes. The grounded theory method was adopted to analyse the data that had been collected. The results showed that for this sample of 20 teachers, student characteristics were important contributing factors to their expectations in the teachers’ university settings. The factors the teachers considered important included students’ (a) prior academic achievement, (b) motivation, (c) study skills, and (d) academic discipline. Also, teacher characteristics were found to be another major source of these university teachers’ expectations, including teachers’ (a) past teaching and learning experience and (b) teaching self-efficacy. The findings suggested that the bases of teacher expectations in higher education may differ from those at the elementary or secondary school level.

试论柳词的俚俗化及其影响

柳永具有独特的经历和个性,在俗文学蓬勃兴起的文化环境中,他专力创作俗词。俚俗的柳词带有市井的色彩,这些作品浅近俚俗,适应市民的情趣、唱出了市民的心声。本文从分析柳词俚俗化的特点入手,阐释了其对俗文学产生的影响。

Comparison of the characteristics of macrophages derived from murine spleen,peritoneal cavity,and bone marrow

Macrophages have a diverse set of functions based upon their activation states. The activation states, including resting (M0) and polarizing (M1 and M2) states, of macrophages derived from the mouse bone marrow, spleen, and peritoneal cavity (BMs, SPMs, and PCMs, respectively) were compared. We evaluated the macrophage yield per mouse and compared the surface markers major histocompatibility complex (MHC) II and CD86 by flow cytometry. The relative mRNA levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, mannose receptor (MR), and Ym1 in the M0, M1, and M2 states were also compared using real-time polymerase chain reaction (PCR) analysis. Bone marrow yielded the most macrophages with the best homogeneity, but they were polarized toward the M2 phenotype. All three types of macrophages had the capacity to polarize into the M1 and M2 states, but SPMs had a stronger capacity to polarize into M1. The three types of macrophages showed no differences in their capacity to polarize into the M2 state. Therefore, the three types of macrophages have distinct characteristics regardless of their resting or polarizing states. Although bone marrow can get large amounts of homogeneous macrophages, the macrophages cannot replace tissue-derived macrophages.     

加强法制教育提高"学困生"德育水平

在加强德育的过程中，最难转变的是“学困生”。因这些“学困生”不但文化基础差，纪律差，而且德育观念也差。怎样才能较好地转化他们，提高他们的德育素质呢？几年来，我在教育实践中加强了法制教育，收到了事半功倍的效果。一、利用法制报刊上的典型案例进行法制教育，帮助他们树立新道德观念“学困生”不仅文化基础差，纪律差，往往法制观念也差。要想提高他们的道德水平，必须“三管齐下”，特别是要加强法制教育，才能标本兼治，彻底转化。１９９５年１０月下旬的一天中午，我刚接任班主任的高二（１）班有６人打了群架，其中有２人当…     

改进深度置信网络在城市用水量预测中的应用

城市用水量的准确预测可以为供水管网智能调度、异常报警提供支持,便于及时发现漏损、排查及检修,具有极大的现实意义与经济利益。针对现有用水量预测方法忽视用水量数据自身特征及不能模拟更复杂的数学运算的问题,提出一种改进深度置信网络（DBN）的用水量预测方法。对有高斯分布的连续受限玻尔兹曼机（CRBM）引入稀疏正则项,解决特征同质化现象的同时也适用于用水量数据输入。实验结果表明,在实际用水量预测中,改进DBN模型相比传统神经网络和传统DBN预测模型,预测准确率得到了较大的提高。
