区域内校际间高考成绩评价的探索与实践——以深圳部分学校2010年高考成绩为例

由于学校之间生源质量和考生规模等方面的客观差异,以升学率或者考上清华、北大的人数评判学校的高考成绩是不科学和不公平的。要在不同的学校之间进行高考成绩的比较或评价,较为科学和公平的思路与方法是将高考结果与其高一生源质量进行比较,着重从学校的“教育教学培养提升能力”来评价,主要的分析和评价指标有百分位变化指数、目标达成度、同名次段人数保持率、相近质量生源考生上线率和平均分等。     

Screening study of transition metal oxide catalysts supported on ceria-modified titania for catalytic oxidation of toluene

Six transition metal oxides were added in ceria-modified titania using a sol-gel method for catalytic oxidation of toluene. An MnOx based catalyst was found to be the most active one, with which toluene could be decomposed completely at 200 °C. The greatest Mn/Ti and molar ratio of the mobile oxygen to the total oxygen concentration, together with a large surface area and a low reduction peak-starting temperature, would result in its best activity in toluene oxidation.     

“It Lets Me Fight the Bad Guys”: An Exploration Into the Factors Predicting Enjoyment of Violent Video Games

In an exploratory survey that sampled video gamers, participants were asked to indicate why they enjoy playing their favorite video game. On the basis of ESRB ratings, we compare those whose favorite game is violent to those whose favorite game is nonviolent. Consistent with self-determination theory, the findings suggest need for autonomy and competence are important motivating factors. However, the findings also suggest fans of violent games differed from fans of nonviolent games in the degree to which arousal, liking violence, playing the vicarious hero, and playing the vicarious villain drive enjoyment. Furthermore, being able to play the hero and “fight bad guys” was a significant predictor of enjoyment of violent games. Implications for self-determination theory and theories of media enjoyment are discussed.     

武夷山脉裸子植物群落分类与分布特点

以群落学的调查方法,对福建武夷山脉13个研究地、4.86 ha样方开展实地调查。通过统计分析,结果表明:武夷山脉裸子植物群落物种组成丰富,维管植物有482种,其中蕨类植物58种、裸子植物39种、种子植物385种。分布于武夷山脉的81个裸子植物群落隶属1个植被型组,4个植被型,4个植被亚型,17个群系组,27个群系。群落的特有性比例高达86%,如南方铁杉林、黄山松林、刺柏林、南方红豆杉林、长叶榧树林等均为我国宝贵的自然资源。暖温性裸子植物群落分布在中低海拔(450 m～1 000 m),温性裸子植物群落分布在中高海拔(800 m～1 800 m);裸子植物群落的数量分布变化从南至北呈现递增趋势。

汉语与维吾尔语比喻辞格喻体来源比较--以《红楼梦》维译本为例

以汉民族为主体的儒家文化和古维吾尔族的文化有两千多年的文化交流史,无论在表层语言方面,还是深层次的对客观世界的感知、联想及把握方面,都有一些相似点。但是作为文化载体的语言必然受制于各自民族的文化特色,因此,体现在比喻辞格中,在喻体选择和喻义理解方面总有交叉的部分。本文主要以维译本《红楼梦》为参照对象,对汉、维比喻中一些常见的喻体和喻义进行梳理比较,以对汉、维设喻的共性和个性作以简要总结。     

Distributed Time Synchronization in Wireless Sensor Networks via Second-Order Consensus Algorithms

This paper proposes a distributed second-order consensus time synchronization, which incorporates the second-order consensus algorithm into wireless sensor networks. Since local clocks may have different skews and offsets, the algorithm is designed to include offset compensation and skew compensation. The local clocks are not directly modified, thus the virtual clocks are built according to the local clocks via the compensation parameters. Each node achieves a virtual consensus clock by periodically updated compensation parameters. Finally, the effectiveness of the proposed algorithm is verified through a number of simulations in a mesh network. It is proved that the proposed algorithm has the advantage of being distributed, asymptotic convergence, and robust to new node joining.     

Neuro-space mapping for modeling heterojunction bipolar transistor

A neuro-space mapping(Neuro-SM) for modeling heterojunction bipolar transistor(HBT) is presented, which can automatically modify the input signals of the given model by neural network. The novel Neuro-SM formulations for DC and small-signal simulation are proposed to obtain the mapping network. Simulation results show that the errors between Neuro-SM models and the accurate data are less than 1%, demonstrating that the accurcy of the proposed method is higher than those of the existing models.
