在大学英语阅读教学中引入英国英语教学专家杰里米·哈默(Jeremy Harmer)的ESA教学模式的三要素(投入-Engage、学习-Study和运用-Activate),通过它们之间顺序的不断变换,创造出多样的教学模式,有效地将传统的以教师课堂讲授为主的活动模式转变为在教师指导下以学生为主体的教学模式,并取得了很好的课堂教学效果。 相似文献

The slow and endogenous twist of economic macro-structure makes up an important evolutionary feature of capitalist economies,
and may be at the root of structural crisis. In this line, a Goodwinian growth model with increasing returns and profit-sharing
that tries to picture a simple scenario of the seventies crisis is considered. It is shown that the exhaustion of the Kaldor-Verdoorn
“productivity law” can entail, in a nonlinear framework, a “catastrophic” bifurcation from a “high” to a “low” growth path.
Slow/fast dynamical systems then allow one to formalize a multiple time-scales dynamics where the growth path is shaped by
the structural framework in which it takes place, but has also a long -un feedback. Structural change and crisis appear as
long term and endogenous outcomes. 相似文献

The westernization of Asian countries has led to the rapid expansion of Western-style fast-food restaurants, which are believed to be fueling an unprecedented rise in body mass in these countries. This study tests this belief using longitudinal data from China. Exploiting the opening of a Western-style fast-food restaurant in a particular community, we conduct a transition analysis to make a more convincing causal interpretation than the standard cross-sectional or fixed-effects approach. Considering several measures of fatness, we find no robust evidence of Western fast food having a substantial effect overall, but there is some indication of effect heterogeneity. 相似文献

The deployment of battery-powered electric bus systems within the public transportation sector plays an important role in increasing energy efficiency and abating emissions. Rising attention is given to bus systems using fast charging technology. This concept requires a comprehensive infrastructure to equip bus routes with charging stations. The combination of charging infrastructure and bus batteries needs a reliable energy supply to maintain a stable bus operation even under demanding conditions. An efficient layout of the charging infrastructure and an appropriate dimensioning of battery capacity are crucial to minimize the total cost of ownership and to enable an energetically feasible bus operation. In this work, the central issue of jointly optimizing the charging infrastructure and battery capacity is described by a capacitated set covering problem. A mixed-integer linear optimization model is developed to determine the minimum number and location of required charging stations for a bus network as well as the adequate battery capacity for each bus line. The bus energy consumption for each route segment is determined based on individual route, bus type, traffic, and other information. Different scenarios are examined in order to assess the influence of charging power, climate, and changing operating conditions. The findings reveal significant differences in terms of required infrastructure. Moreover, the results highlight a trade-off between battery capacity and charging infrastructure under different operational and infrastructure conditions. This paper addresses upcoming challenges for transport authorities during the electrification process of the bus fleets and sharpens the focus on infrastructural issues related to the fast charging concept. 相似文献
