大学英语听力课堂中的学习策略教学

本研究首先于Anderson的认知技能获得模式和听力理解过程工作模式的理论基础上建立了一个新的基于学习者的四步策略训练模式,使得策略训练更有针对性和可操作性,即1)决定学习者的需要及选择好要教的策略,2)实施策略训练,3)评估策略训练,4)修订策略训练。这四个步骤循环贯穿于培训过程的始终。然后文章以一次为期二十周的听力策略训练证实了策略培训及以上训练模式的有效性。实验对象为本文作者所教授的两个自然班共116名福州大学工程技术学院的非英语专业的学生,两个班分别组成实验组和对照组接受为期20周的实验教学,并接受前后听力测试。数据分析则在实验教学和测试成绩的增加中寻找联系。结果证明,后测中的实验组成绩明显优于控制组,即上述理论框架指导下的听力策略培训能有效地促进学生听力水平的提高,且培训的有效性因学生听力水平的不同而不同。     

农业结构调整：世纪初中国农业的现实选择

对农业结构进行战略性调整 ,既是增加农民收入、促进农村经济发展的迫切需要 ,也是加入WTO增强我国农业国际竞争力的客观要求。为此 ,我们既要具备调整农业结构的战略思路 ,同时还要从转变政府职能、培育龙头企业、加强农业组织创新、建立农业风险保障基金等具体对策入手 ,稳妥地推进我国农业结构的调整。

Suspect Height Estimation Using the Faro Focus3D Laser Scanner

At present, very little research has been devoted to investigating the ability of laser scanning technology to accurately measure height from surveillance video. The goal of this study was to test the accuracy of one particular laser scanner to estimate suspect height from video footage. The known heights of 10 individuals were measured using an anthropometer. The individuals were then recorded on video walking along a predetermined path in a simulated crime scene environment both with and without headwear. The difference between the known heights and the estimated heights obtained from the laser scanner software were compared using a one-way t-test. The height estimates obtained from the software were not significantly different from the known heights whether individuals were wearing headwear (p = 0.186) or not (p = 0.707). Thus, laser scanning is one technique that could potentially be used by investigators to determine suspect height from video footage.     

组织双元性、创新协同与企业绩效:基于战略一致性的调节作用

技术创新与管理创新的协同机理及其对企业绩效的影响机制和作用边界存在较大研究空白。本文基于组织双元性理论和协同理论,在分析双元性技术创新和管理创新动态协同机理的基础上,实证检验了探索式和利用式技术创新与管理创新的协同效应对企业短期和长期绩效的影响以及战略一致性的调节作用。研究表明,探索式和利用式创新与管理创新的协同对企业短期和长期绩效均有显著促进作用;探索创新与管理创新的协同对企业长期绩效的贡献高于利用式创新,而利用式创新与管理创新的协同对企业短期绩效的贡献高于探索式创新;战略一致性在创新协同与企业绩效的关系中具有正向调节作用,战略一致性越高,创新协同对短期和长期绩效的促进效应越显著。     

Physical growth and ethnic inequality in New Zealand prisons, 1840–1975

The British colonization of New Zealand after 1840 was marked by an unusual concern compared to other settler colonies to incorporate the indigenous Māori population into the new society. But despite a continuing political rhetoric of protection and sovereignty, Māori have historically had lower living standards and, since the 1920s, higher rates of incarceration than European-descended New Zealanders (Pākehā). In this article, the authors examine differences between Māori and Pākehā over 130 years using prison records. Aggregate data from the Ministry of Justice shows long-term change and differences in incarceration rates. Using a data set of all extant registers of men entering New Zealand prisons, the authors show change over time in convictions and in height. The adult statures of Māori and Pākehā were similar for men born before 1900, but marked differences emerged among cohorts born during the twentieth century. By the Second World War, the gap in adult stature widened to around 3 cm, before narrowing for men born after the Second World War. Periods of divergence in stature are paralleled by divergence in fertility and indicators of family size, suggesting the possibility that increasing fertility stressed the economic situation of Māori families. The prison evidence suggests that inequalities in ‘net nutrition’ between Māori and Pākehā are long-standing but not unchanging – indeed, they increased for cohorts born in the early twentieth century. A subset of the data describing adolescents confirms that, among those born after 1945, the ethnic differential was already visible by the age of 16.
