Multivariate prediction of academic performance by Hong Kong University students

Verbal intelligence, English-language skills, personality, and attitude scales were used as predictors of academic performance in 230 male and female arts students at the University of Hong Kong. A series of bivariate, multiple, and canonical correlation analyses were performed. The results showed that verbal intelligence and attitudes, excepting study orientation, were not predictive of performance. English-language skills had the most predictive value, accounting for about 10% of the variance of performance measures. Personality variables failed to predict performance when composite criterion measures (GPAs) were used; however, they proved to be of predictive value when results of individual academic subjects were used as criterion measures. The study points to the importance of using noncomposite criterion measures in prediction and of considering the cultural context of achievement.

以语音识别为基础的音乐检索系统

针对一般的语音识别算法均存在抗噪能力不好的问题,无法满足音乐检索系统的需求。针对于此,本文以抗噪能力为基础对MFCC语音识别算法进行了优化,第一步是通过F比方法加权优化了MFCC算法的特征参数,估计出各维特征分量对识别率的影响,并将其提取出来,然后采用主成分分析法对提取的特征分量进行降维处理,以降低计算复杂度,减少数据存储量,加快训练时间,最终提高识别效率。算法仿真结果表明,本文提出的基于抗噪能力优化的MFCC语音识别算法具有较好的抗噪能力,比传统MFCC算法对音乐检索的精确度更高。

水杨酸对铅胁迫下玉米幼苗生理特性的影响

以玉米种子为试验材料,采用砂培法研究了水杨酸(SA)对铅(Pb2+)胁迫下玉米种子的萌发、叶绿素含量、MDA含量、POD活性、等方面的影响。结果表明:低浓度的SA≤80mg/L时,能促进铅胁迫下玉米幼苗的生长,表现为玉米种子的发芽率增大,幼苗根长的增加,叶绿素含量增大,MDA的含量降低,POD活性升高,等。当SA浓度为60mg/L～80mg/L,Pb2+≤1mg/L时,SA对Pb2+的解毒效应最明显,当SA浓度为100mg/L,Pb2+为8mg/L时,SA与Pb2+协同迫害幼苗的生长。     

锦屏一级水电站坝基f2断层水泥灌浆施工技术

断层及层间挤压错动带采用高压水冲洗置换灌浆的方式进行处理,能够冲洗出一部分软弱介质,冲洗后的空腔再采用水泥浆液进行置换固结灌浆,相当于在断层上施加了水泥柱桩,提高了断层基础的承载力。本文介绍锦屏一级水电站大坝左岸f2断层高压冲洗水泥置换灌浆加固施工技术的成功运用。     

从艾森豪威尔到肯尼迪:美国对日政策的转变

1960年日本"安保危机"之后的困局促使美国对日政策从"占领者"心态向"平等伙伴关系"心态转变。艾森豪威尔时期的美日关系虽然得到了很大程度上的改变,但是,美国对日政策仍带有很强的"占领者"色彩。肯尼迪时期,美国适应新形势的需要,着手调整对日政策,采取了"单边"贸易自由化、美日事前协商框架等政策,开始向"平等伙伴关系"转变,试图重构美日关系。     

Multinational subsidiary knowledge protection—Do mandates and clusters matter?

International knowledge spillovers, especially through multinational companies (MNCs), have recently been a major topic of academic and management debate. However, most studies treat MNC subsidiaries as relatively passive actors. We challenge this assumption by investigating the drivers of knowledge protection intensity of MNC subsidiaries. We argue that knowledge protection intensity is determined by MNC subsidiary mandates and by opportunities and risks originating from the host region. We hypothesize that not just competence-creating but also competence-exploiting mandates increase knowledge protection intensity. In addition, technological cluster regions in the host country can be expected to provide opportunities for knowledge sourcing and MNC subsidiaries may be willing to protect knowledge less intensively to participate in cluster networks. We test our hypotheses using a dataset of 694 observations of 631 MNC subsidiaries in Germany and develop recommendations for research, managers and policy makers.
