论新课程改革中的教师课程角色定位

教师的“课程角色”是20世纪70年代以后逐渐在课程研究领域凸现的一个术语。教师是课程改革过程中最直接的参与者，新的课程计划成功与否，教师的素质、态度、适应和提高是一个关键因素。事实表明，一些课程计划没有取得预期结果，并不是课程计划本身的问题，而是由于教师不积极参与或不能适应的缘故。随着新一轮基础教育课程改革的不断推进，有关课程对教师挑战的研究不断出现。

Primary Mental Abilities at collective and individual levels.

Scores in ability tests administered to approximately 2,780 4th–9th graders were decomposed into district, class, and individual components. Demographic characteristics of neighborhoods, self-selection between academic and general programs, emphasis in instruction, irregularities in test administration were used to explain the variation between schools and districts. First-order factor analyses at the individual level showed the usual Primary Mental Abilities test pattern. Second-order analyses grouped the primary factors into one Power and one Speed factor. This latter structure was found also in the analyses of class means, although the processes behind the factors were likely to be different from those operating at the individual level.

Investigative study into the hydrodynamics of heap leaching processes

Three mathematical models (mixed side-pore diffusion (MSPD) and profile side-pore diffusion (PSPD) with uniform or distributed pore lengths) are derived in dimensionless form to simulate the transport of solutes through the flowing channels and the stagnant pores of an unsaturated heap. Model parameters are determined from experimental tracer residence-time distributions using the least-squares minimization approach. It is shown that the residence-time distribution curves display a long tail resulting from the very slow mass transfer (or diffusion) into the 1- to 6-cm-long stagnant pores, which take up 5 times more space than the flowing liquid. The very large coefficients of determination (R ²>0.99) confirm the validity of all models and especially that of the PSPD model with a distributed pore length. The effects of five factors (agglomeration, addition of binder, particle size, solution flow rate, and bed height) are examined. Data from experimental residence-time distributions prove that the advection time is directly proportional to the column height and inversely proportional to the flow rate. The two estimated parameters (stagnant liquid holdup and pore length) are only marginally affected by any change in crush size, agglomeration technique, or operating conditions. This, in turn, suggests that the model can predict and/or simulate the hydrodynamic behavior in taller columns and, possibly, heaps.

关于中小学办学特色研究文献述评

对于什么是学校办学特色这个问题,不同的学者有不同的理解和表述.从总体上来看,办学特色是指在发展历程中形成的比较持久稳定的发展方式和被社会公认的、独特的、优良的办学特征.办学特色能够为学校带来活力,为老百姓提供优质教育.一所学校要真正办出特色,最关键的要具备两点:一是有一个宽松的外部环境,一是要有一个有思想、有理想的教育家式的校长(或书记).同时,办学特色的形成是一个持续不断的过程,需要遵循教育规律,找寻到合适的突破点,在教学实践中逐步达成.     

Long Term Landfill Primary and Secondary Leachate Production

This study evaluated long term primary and secondary leachate production from operating landfills in the northeastern United States. The data were obtained for periods when the landfills were in use (open) and were covered (closed). During the open period of operation, primary leachate production was 64% of the precipitation that fell on the site. After landfill cell closure, the primary leachate production declined and, four years after closure, such production reached quasi-equilibrium and averaged 2% of the precipitation. For secondary leachate production during the open and closed period, such production was 1 and 0.25% of the precipitation, respectively.

Advanced Review on Extraction of Nickel from Primary and Secondary Sources

In this review, resources of nickel and status of different processes/technologies in vogue or being developed for extraction of nickel and associated metals from both primary and secondary resources are summarized. Nickel extraction from primary resources such as ores/minerals (sulfides, arsenides, silicates, and oxides) including the unconventional one viz., the polymetallic sea nodules, and various secondary resources has been examined. Though sulfide ores after concentration are generally treated by the pyro-metallurgical route, most processes for lateritic ores deal with either the acid leaching at ambient temperature and pressure, or high pressure, and a few based on the microbial treatment and owing to the extensive research on laterites, a special emphasis is put forth in this review. Prominent sources that are covered in some detail include the solid wastes like spent batteries viz., end-of-life nickel-cadmium (NiCd) and nickel metal hydride (NiMH), spent catalysts, and spent/scrap superalloys, and liquid wastes such as copper bleed stream and electroplating effluents. In particular pre-treatment of the spent nickel-based batteries, leaching of metals from the electrode materials in different lixiviants, besides separation/solvent extraction of nickel/other metals from the leach liquors, are highlighted.
