探究数字化时代对师范生信息素养的要求

本文从数字化时代发展的角度出发,指出数字化学习不仅是数字时代学习的重要方式,更是课程整合的核心,同时提高教师的信息素养是数字化学习的关键。随着信息社会的发展和中小学信息技术课的开展,对师范生的信息素养提出了更高的要求。目前师范生就业形式,信息素养状况怎样,存在哪些问题,怎样去解决这些问题提高自身的竞争力?这都是我们师范院校的学生所思考的问题。针对上述问题,本文提出了自己的观点和看法。

Patterns of growth in Chinese cities: Implications of the land lease

A special feature of China’s housing market is land use rights in the form of land leasehold contracts granted by the government. We consider an equilibrium model in which a representative developer may choose to redevelop existing centrally located housing or to develop new housing at the periphery of the city. We show that as the city grows, the land leasehold system results in the city center being developed less intensely and more land being used on the outskirts of the city when compared to a fee simple environment. Thus, cities in China are likely to be relatively more spread out, with city centers relatively older than would be the case with “fee simple” ownership. Our model suggests that excess residential land use is about 6 percent. In addition, compared with the ownership case, housing supply will grow more quickly in the near future, but more slowly later on during the transition of the Chinese economy. Parallel to the supply growth pattern, equilibrium price grows relative slowly in the near future, but more quickly later on. While we focus on residential uses, we believe our model can be applied to other land uses.     

Pioneering strategies in the digital world. Insights from the Axel Springer case

Digital technologies present some distinctive characteristics; they simultaneously enable pervasive connectivity, immediacy of interactions and wide access to data and computing power. Based on a detailed historical analysis of Axel Springer, we suggest that pioneering strategies in new markets created by the diffusion of digital technologies are negatively moderated by the fit between firms’ legacy core capabilities and those required to enter the new market. We then show that pioneering strategies in non-core legacy markets are instrumental in creating the capabilities necessary for the sustainability of first-mover advantages (FMA) in the legacy core markets. Finally, we show the role of managerial cognition as a key individual-level enabler in achieving pioneering advantages.

Could the Faustmann model have an interior minimum solution?

The growth of an even-aged stand usually follows a S-shaped pattern, implying that the growth function is convex when stand age is low and concave when stand age is high. Given such a growth function, the Faustmann model could in theory have multiple optima and hence an interior local minimum solution. To ensure that the rotation age at which the first derivative of the land expectation value equals zero is a maximum, it is often assumed that the growth function is concave in stand age. Yet there is no convincing argument for excluding the possibility of conducting the final harvest before the growth function changes to concave. We argue that under normal circumstances the Faustmann model does not have any interior minimum. It is neither necessary nor proper to assume that the growth function is concave in the vicinity of the optimal rotation age. When the interest rate is high, the optimal rotation may lie in the interval on which the growth function is convex, i.e. before volume or value growth culminates.     

A field experiment investigating age discrimination in four European labour markets

In a field experiment investigating age discrimination, pairs of men, aged 27 and 47, inquired about employment as waiters in towns across England, France, Germany and Spain. Statistically significant discrimination against the older waiter was found in all four countries, but it was considerably higher in France and Spain than in England and Germany.
