信息化条件下大学生学习方式的变革研究

我国大学学习的基本特征是自主学习为主,主要培养的是研究、创新性人才。旨在于让大学生学会学习,从而达到提高学习效果和教学质量,造就创新性人才的目的。在信息化条件下,大学生的学习方式随之发生了巨大的变革,网络学习、移动学习、微课等应运而生,如何运用合适的引导策略,营造良好的信息化学习氛围,完成自主、合作、探究学习方式的有效衔接,达到增强大学生获取知识的能力,是高校急需研究的问题之一。     

莎士比亚戏剧中的母亲形象探析

莎士比亚戏剧创作的不同时期都塑造有母亲形象。这些形象既有共性特征又有时代的形象流变。总体而言,莎士比亚戏剧作品中的母亲形象经历了由最初的共性突出到第二时期的个性突出,再到第三时期共性与个性双重模糊的变化过程,这种形象的流变打上了深刻的时代烙印。     

语言中的“反”性别歧视

语言是社会的镜子,同样也随着时代的脚步而逐步更新,它过滤了违背时代潮流的“旧语”,也推出了顺应时代潮流的“新语”。而语言性别歧视话题几经斗争和演变,也都将会在语言这面镜子中得到修正和完善。传统上人们总是片面地认为性别歧视语言主要针对女性,而忽视了对男性的语言歧视;并且,既然性别歧视语言是在历史发展中产生的,那么也必然会随着历史发展而演变。因此,该文从相反的视角,提出“反”性别歧视---一方面研究女性在语言歧视中的“反抗”,另一方面也探究女性“反过来”针对男性的歧视。     

本科生学习“数学物理方程”的阶段性影响因素分析

从调查本科二年级学生学习“数学物理方程”的状态出发,应用已修订的布鲁纳学习认知策略量表及Gjesme和Nygard成就动机量表,分析学生在学习数学物理方程课程的上中下三个学习阶段学生学习状态与心理变化,找出阶段性影响的主要因素,并对课程成绩与各策略维度相关性进行分析,发现中期是本科生学习状态的转折点,学生虽未能把握好元认知学习策略,但临近考核时具有一定的自控能力,而个人兴趣与自身的学习能力可能决定成绩的高低。

The role of technological catch up and domestic market growth in the genesis of emerging country based multinationals

The paper presents a model that evaluates how upgraded technological capabilities of emerging country based multinationals (EMNCs) and an increase in the domestic market size of large emerging countries affect value chain location choices and the competitiveness of emerging country based firms versus advanced country based ones. The model shows that, even without possessing a competitive advantage in terms of technology and/or brands, EMNCs from large or rapidly technologically advancing countries can become dominant players in the global system. The model highlights the central role of firm level technological intensity and product differentiation in determining the location of value chain activities as well as defining organisational boundaries. Empirical analysis of the location choices of the world's top multinationals from large advanced and emerging countries in 2010 supports the model's predictions.     

Is small actually big? The chaos of technological change

In this paper, we develop themes from complexity and chaos theory that help to explain the technological change process. We apply two quantifiers, correlation dimensions and Lyapunov exponents, to examine the signs and degrees of chaotic technological dynamics. To illustrate our ideas, we study the development of electronic displays from 1976 to 2010, using patent data. The results of the chaos model are matched against the profiles of patent citations. Our analysis contributes to the development of a chaotic model of technological change.     

Technological change in U.S. jet fighter aircraft

This paper quantitatively measures technological change in U.S. jet fighter aircraft from 1944 to the present day using the hedonic pricing approach. The technical and performance characteristics of jet fighters have changed dramatically between the time they were first developed at the beginning of the 1940s and the present. Parallel to this technological change there has been a sharp escalation in costs regarding the new generations of jet fighter aircraft. We estimate a measure of price for the performance and technical characteristics of these aircraft. Embodied technological change in jet fighter airframes is measured using quality-adjusted prices. Although the flyaway cost of jet fighter aircraft has soared, on average, by about 12.63% per year, the quality-adjusted aircraft cost has only risen by about 2.6% per year, a figure lower than the average observed general inflation rate for the period (around 4%). This represents an impressive average technological progress ratio of around 10% per year. A revealed preferences argument shows that the characteristic most valued by the government is stealth capability, followed by advanced avionics.     

Light emitting diodes and the lighting revolution: The emergence of a solid-state lighting industry

Emergence of new industries from evolving technologies is critical to the global economy, yet has been relatively understudied due to the paucity of available data. This study draws lessons on industry emergence, by analyzing how a solid-state lighting (SSL) industry grew out of light emitting diode (LED) technologies that evolved for half a century, with participation by tens of thousands of researchers in universities, national laboratories, and firms. Using data on publications, patents, and firms combined with business history we trace the evolution of SSL through a succession of market niches. At times a few researchers with unorthodox research approaches made breakthroughs that greatly advanced particular technology trajectories and pushed LED research in unexpected directions. A succession of LED market niches advanced the technology and provided profits to incentivize continuing research while reducing cost and improving efficacy of LEDs. Innovating firms developed a thicket of patents and captured substantial profit, but were embroiled in extensive litigation that was ultimately resolved through cross-licensing. A major new generation of lighting products is now disrupting the traditional lighting industry. Although the leading incumbent lighting firms all invested early and heavily in SSL, the industry's future leadership is uncertain.
