新农村建设中的资源开发与环境保护——以湖北省保康县马桥镇尧治河村为例

我国新农村建设中资源开发与环境保护存在的主要问题是资源开采规模普遍较小,环保措施不到位;过度开发,不注重生态平衡;只顾初级开采,忽视深度开发、轻视加工利用,无可持继发展规划;开发产生的"三废",形成新的污染源。问题产生的根源是认识不足;缺乏有效的政策和法律体系;资源开发利用缺乏总体规划;尚未形成政府推动、市场驱动、公众行动的运行机制。应该从建立统筹城乡与区域的资源开发与环境保护管理机制;建立合理的循环经济模式;做强加工业,提高资源的循环利用率;调整农村产业结构、扩大就业、实现农民增收;加快立法进程,加大执法力度;加强宣传教育、增强农民环保意识;坚持从"九节一减"等方面来解决我国新农村建设中资源开发与环境保护问题。     

高校新办专业的控制与发展

随着社会的不断进步、社会分工的不断细化,新兴产业不断出现,高校的新办专业不断增加。加强新专业建设,提升新专业办学质量势在必行。高校在新专业建设过程中一定要正确定位,充分发挥自己的优势。新专业建设发展规划要科学,结构要合理。重点放在加强专业师资队伍建设、科研团队组建及实习基地的建设上,同时保证人、财、物的大力投入,以改善新专业办学条件。     

基于m-相依序列的学习机器相对一致收敛的界

为了研究m-相依序列下学习机器的推广性能,把基于独立同分布的结果推广到m-相依序列,建立采用ERM算法的学习机器的经验风险到它的期望风险相对一致收敛速率的界.并对m-相依序列现有的结论进行改进,得到了m-相依序列下,采用经验风险最小化算法学习机器的推广性能的界.     

新乡土社会与马克思主义大众化

自马克思主义传入中国,乡土社会中就一直进行着马克思主义大众化的历程。新时期,乡村社会出现了一系列新的特征,＂传统乡土社会＂转向＂新乡土社会＂,新乡土社会就成为了马克思主义大众化的重要场域。因此,在新的境遇下实现马克思主义大众化就必须结合新乡土社会的实际,契合新乡土社会的文化,结合时代发展的特征,发挥农村精英分子的作用。     

高职非英语专业新生英语词汇学习策略运用的研究

笔者从学生默写、作业和试卷中发现高职学生在词汇记忆和运用上存在不少问题,本文试采用问卷和采访两种方式,对高职某班非英语专业新生的英语词汇学习策略的运用进行了调查。在此基础上,本文提出了培养和提高学生词汇记忆能力和词汇运用能力的建议。     

基于工作过程的学习领域课程体系的开发与实践——以高职物流管理专业为例

基于工作过程的学习领域课程体系的开发,是高职教育内涵建设的前沿课题。本文以学习领域课程体系开发的基本理念为指导,分析当前高职物流管理专业职业岗位和培养目标;然后结合我校实际,以国际物流、金融物流方向的工作流程为主线,确定各方向的学习领域课程体系,并对物流采购管理学习领域课程开发进行实践;最后对学习领域课程的教学实施进行探讨。     

中日新数学教科书中的“勾股定理”

由于勾股定理在数学及数学教育中的特殊地位,它几乎是全世界的中学数学课程都要介绍的内容.从教科书内容的广度和深度来看,《中学数学》最难,《数学》次之,New Mathematics Counts最易;《中学数学》和New Mathematics Counts对勾股定理的发现和证明做了弱化处理;《数学》重视对勾股定理的证明,向学生展现了多元文化背景下的数学内容;3种教科书对定理的应用都很重视,都给出了一定数量的例题和习题.     

关于中共“一大”代表王尽美四个历史问题的考证

通过进一步研究发现,王尽美共接受11年学校教育,先读了4年私塾,又插班读完初等小学,接着又读了2年高等小学,接受了3年师范教育,并没有取得山东第一师范学校的中师毕业文凭,所以,王尽美是高小毕业;1923年前后,王尽美离开山东与尹宽、陈独秀没有任何关系;王尽美病故前对同事是有交待的,对此还需进一步挖掘。     

Suitability of school textbooks for 5 to 7 year old children with colour vision deficiencies

Purpose

The aim of the present study was to determine, through colorimetric analysis, whether school textbooks for children aged 5 to 7 years contained tasks requiring normal colour vision discrimination for their resolution. In addition, the performance of a group of observers with diverse colour vision deficiencies was evaluated while conducting the tasks under analysis.

Results

Textbooks of mathematics were found to include 10% of tasks which, to an observer with colour vision deficiency, would be very difficult or impossible to solve. The level of difficulty of each task was influenced by the type and degree of colour vision deficiency and by the actual ambient illumination under which it was observed.

Conclusions

Some school textbooks need to be redesigned through an alternative use of colours and textures to take into consideration colour vision deficiencies. In view of the present findings, many Spanish editorial boards have committed to undertake these changes.     

Comparing active delay and procrastination from a self-regulated learning perspective

Researchers have proposed that the act of postponing academic work may be divided into a traditional definition of procrastination, viewed as maladaptive, and adaptive forms of delay. Adaptive forms of delay may be more consistent with certain facets of self-regulated learning. The current study investigated this issue by examining whether the relations between aspects of self-regulated learning and active delay may be distinct from the relations these aspects of self-regulated learning have with procrastination. Among 206 undergraduates, procrastination was positively predicted by mastery-avoidance goals and negatively by metacognitive strategy usage, whereas active delay was negatively predicted by avoidance goals and positively by self-efficacy. Furthermore, students who reported higher levels of active delay also received better grades. These findings provide support that active delay is a distinct form of delay from procrastination that may be more positive due to its associations with some adaptive self-regulatory processes and academic achievement.
