The present Vygotskian community is divided by a common language, 1 argue. By closer inspection there appears to be 2 quotation communities. The reasons for this are many, but the main reason seems to be the different reception histories of Vygosky's work in Russia and in the U. S., respectively. Concurrently, on the continent there also exist 2 different quotation communities. In one community Vygotsky's work initially was introduced through his Russian disciples; in the other community through his American adherents. This article focuses on a Vygotsky‐inspired curriculum rationale that is not yet widely known abroad. It is authored by El ‘konin and Davydov. In Russian parlance this approach is called Developmental Education. By closer inspection it turns out that there is a remarkable family resemblance between this approach and the American approach known as the Schools‐for‐Thought movement. Here both approaches are juxtaposed and critically valued. 相似文献

Becker and Barro (1988) formulated a theoretical model which identified a range of macroeconomic variables which can temporarily
or permanently affect fertility in small open economies. This article tests the Becker-Barro model with relevant data which
covers most of the 20th century for two small open economies, namely The Netherlands and New Zealand. The results show that
government subsidies for having children have a strong positive effect on fertility, while the provision of public pensions
has a strong negative effect. The degree of intergenerational altruism appears to have been declining. Moreover, there is
only weak support for the hypothesis that real interest rates positively influence fertility.

In the most advanced countries, child mortality and adult mortality under age 65 years have fallen so low that further improvement in life expectancy relies almost completely on the decline of mortality at older ages. This phenomenon is particularly pronounced among women, who are far ahead of men in survival rates. Thus, to project the future of life expectancy, this study focuses on trends in female life expectancy at ages 65 and older. Four countries are selected for this analysis: the United States, Netherlands, France, and Japan. It is particularly interesting to understand why American and Dutch trends in female old‐age mortality have been diverging from those in France and Japan for two decades. It is shown here that most of the divergence derives from the fact that decline in cardiovascular mortality is more and more offset by increases in other causes of death in the United States and the Netherlands, while the other two countries are more successful in reducing mortality from all causes at increasingly older ages. This latter phenomenon could represent a new stage of the health transition. 相似文献

The concept of strategic control as described by the authors [8] partitions the decision horizon of the firm into two segments. In the long term, information is not precise, goals are vague and constraints are unclear. The problem for the firm is, in spite of this ambiguity, to establish a development window at the beginning of this period that reflects long-run factors and can serve as a guide for short-term behaviour. In the short run, information is precise enough for conventional mathematical programming models to be used to guide attainment of the development window. This paper presents an analytic model that solves the long-run problem defined by the strategic control framework and generates the required development window. A numerical example is presented for illustrative purposes. 相似文献
