儿童问题行为的评估及其对策   总被引：1，自引：0，他引：1  

尹秀艳 《鞍山师范学院学报》2006,8(6):82-85

儿童问题行为是国内外心理学和教育工作者共同关注的热点问题,其发生率仍在逐年上升.儿童问题行为不仅影响儿童身心的健康发展,而且影响我国素质教育的进程.在教育过程中,教育者只有对儿童的各种行为表现做出合理的评估,才能够有针对性地实施教育计划.本文对儿童问题行为的评估标准、注意问题和对策等方面作了初步探讨.  相似文献   

学生伤害事故处理:一个“有条件”的《办法》   总被引：2，自引：0，他引：2  

尹力 《教育理论与实践》2003,(21)

由教育部制定的《学生伤害事故处理办法》(以下简称《办法》),已于2002年9月1日起施行。《办法》的出台,让人惊喜之余,也让人深思:1.如果《办法》的目的要保护学校的合法权益,则在具体规定上会倾向于校方的利益,如诸多“有条件的”规定,难以从根本上保护学生的合法权益;2.规定由主管的教育行政机关进行调解是不合适的;3.由学生承担举证责任显失公平;4.由学校负担的赔偿金,不应当由学校负责筹措,而应当由举办者筹措;5.《办法》属于政府部门规章,教育部作为行政机关无权规定民事诉讼中的责任。所以,《办法》在法院判案时只能作为参考,并不能作为判案依据。在当今这样一个关注人权的时代,学生伤害事故的处理是不容许讲“条件”的,是“无条件”、而不应该是“有条件”的。  相似文献   

Studies on solar flat plate collector evaporation systems for tannery effluent （soak liquor）     

SRITHAR K. MANI A 《浙江大学学报(A卷英文版)》2006,7(11):1870-1877

INTRODUCTION The tannery effluent (soak liquor) spewed out by tanneries to the surroundings has been polluting the land and water bodies in and around the tanneries and is evaporated over a period of time. The rate of evaporation over this period is small in the natural evaporative ponds and so large area is required. But land in urban and semi-urban sectors is scarce and very costly. Hence, it is required to augment the evaporation rate by adopting some suitable techniques. The rate of e…  相似文献   

废聚酯醇解产物羟值的分析方法     

郭金枝 《新乡教育学院学报》2004,17(4):125-127

采用乙酸酐 /吡啶回流法和乙酸酐 /高氯酸 /乙酸乙酯常温酰化法 ,分别测定了废聚醋醇解产物的羟值。结果表明 ,两种方法测定结果均准确可靠。乙酸酐 /吡啶回流法适用于所有的废聚酯醇解产物 ,但操作麻烦、费时。乙酸酐 /高氯酸 /乙酸乙酯常温酰化法用于深度醇解的醇解产物 ,操作简单、快捷  相似文献

我国中小企业缺乏公平竞争发展环境.入世后,中小企业将获得国民待遇,并将在大型国有企业和国外大公司竞争中坐收渔翁之利.政府应尽快给中小企业提供公平的竞争环境和多渠道的融资方式.  相似文献   

稀土族Pm和Tm基上二元合金固溶度的椭圆区分法预测     

廖树帜  张邦维  欧阳义芳 《湖南师范大学教育科学学报》1994,(2)

利用张邦维等提出的键参数函数y=(z/r_k)·[x_p-1/3(z/r?+2)]·x_p和尺寸因素x=R方法对稀土族Pm、Tm两元素基上的室温下固溶度做椭圆(x-m)~2/c~2+(y-n)~2/d~2=1预测,从该方法对23个过渡族基、18个简单元素基、13个稀土族元系基和3个锕系元素基上的二元合金固溶度的研究结果和已有的数据及与Villars的预测结果比较来看,本文的预测结果是可靠的。  相似文献

Problems of drinking water treatment along Ismailia Canal Province, Egypt     

Geriesh MH  Balke KD  El-Rayes AE 《Journal of Zhejiang University. Science. B》2008,9(3):232-242

The present drinking water purification system in Egypt Uses surface water as a raw water supply without a pre-liminary filtration process.On the other hand,chlorine gas iS added as a disinfectant agent in two steps,pre- and post.chlorination.Due to these reasons most of water treatment plants suffer low fltering effectiveness and produce the trihalomethane (THM) species as a chlorination by-product.The Ismailia Canal represents the most distal downstream of the main Nile Rivet.ThUS its water contains all the proceeded pollutants discharged into the Nile.In addition.the downstream reaches of the canal act as an agricultural drain during the closing period of the High Dam gates in January and February every year.Moreover,the wide in-dustrial zone along the upstream course of the carlal enriches the canal water with high concentrations of heavy metals.The obtained results indicate that the canal gains up to 24.06×106m3 of water from the surrounding shallow aquifer during the closing period ofthe High Dam gates,while during the rest ofthe year,the callal acts as an influent stream losing about 99.6×106m3 of its water budget.The reduction oftotaI organic carbon(TOC) and suspended particulate mattes(SPMs)should be one of the central goals of any treatment plan to avoid the disinfectants by-products.The combination of sedimentation basins.gravel pre-filtration and slow sand filtration,and underground passage with microbiological oxidation-reduction and adsorption criteria showed good removal of parasites and bacteria and complete elimination of TOC.SPM and heavy metals.Moreover,it reduces the use of disinfectants chemicals and lowers the treatment costs.However,this purification system under the arid climate prevailing in Egypt should be tested and modified prior to application.  相似文献   

Enhanced primary treatment of low-concentration municipal wastewater by means of bio-flocculant Pullulan     

YANG Kai YANG Xiao-Jun YANG Mo 《浙江大学学报(A卷英文版)》2007,8(5):719-723

Jar tests were conducted to investigate the performance of enhanced primary treatment processes for low-concentra-tion municipal wastewater from South China by using composite flocculant combined with bio-flocculants Pullulan and poly-aluminum-chloride (PAC). The optimum dosage for composite flocculant and conditions for flocculation were determined. The experimental results indicated that composite flocculant had high efficiency for removing over 95% of turbidity, over 58% of CODCr (chemical oxygen demand determined with potassium dichromate), over 91% of TP (total phosphate), and over 15% of NH3-N. Moreover, it could improve sludge settling and dehydration properties, and decrease the treatment cost.  相似文献
