作为理论的"文化唯物主义"是汤普森在探索马克思主义英国化过程中,基于自己对斯大林主义的批判反思和历史研究实践,形成的一种主要适用于自由资本主义时代的历史唯物主义学说。作为范式的"文化唯物主义"是奠基在"自下而上"的观察视角、"人民历史"观念和超越资本主义的乌托邦议程这三个支撑点上的,它具有两种基本作用:真实的经验整体的倾听和再创造;大众文化的社会功能的分析与评价。 相似文献

Saving behaviour and earnings uncertainty: Evidence from the British Household Panel Survey 总被引:1,自引:0,他引:1
Alessandra Guariglia 《Journal of population economics》2001,14(4):619-634
For the first time, this paper uses a panel data set, the British Household Panel Survey, to analyse saving behaviour in
Britain. One objective is to test the precautionary saving hypothesis, according to which households save to self-insure against
uncertainty. Our results show that in accordance with this hypothesis, various measures of uncertainty based on earnings variability
have a statistically significant effect on households' saving decisions. Moreover, in accordance with the life cycle model,
households save more if they expect their financial situation to deteriorate.

The purpose of this article is to construct a theoretical framework characterizing the interactions among economic development,
ecosystem equilibrium and possible population decline, and to discuss the population dynamics in the very long run. In our
framework, economic activities bridge population and environment. On the one hand, human beings reform the environment through
economic activities; on the other hand, economic activities decrease environmental resilience and increase the possibility
of an environmental change in a discontinuous and irreversible pattern, as described in Arrow et al. (1995). Furthermore,
a highly developed economy also causes over-specialization of human adaptation, which tends to exaggerate the impact of an
environmental change on human population size.

Since the implementation of the International Conference on Harmonization (ICH) E14 guideline in 2005, regulators have required a “thorough QTc” (TQT) study for evaluating the effects of investigational drugs on delayed cardiac repolarization as manifested by a prolonged QTc interval. However, TQT studies have increasingly been viewed unfavorably because of their low cost effectiveness. Several researchers have noted that a robust drug concentration‐QTc (conc‐QTc) modeling assessment in early phase development should, in most cases, obviate the need for a subsequent TQT study. In December 2015, ICH released an “E14 Q&As (R3)” document supporting the use of conc‐QTc modeling for regulatory decisions. In this article, we propose a simple improvement of two popular conc‐QTc assessment methods for typical first‐in‐human crossover‐like single ascending dose clinical pharmacology trials. The improvement is achieved, in part, by leveraging routinely encountered (and expected) intrasubject correlation patterns encountered in such trials. A real example involving a single ascending dose and corresponding TQT trial, along with results from a simulation study, illustrate the strong performance of the proposed method. The improved conc‐QTc assessment will further enable highly reliable go/no‐go decisions in early phase clinical development and deliver results that support subsequent TQT study waivers by regulators. 相似文献

In this article we discuss various strategies for constructing bivariate Kumaraswamy distributions. As alternatives to the Nadarajah et al. (2011) bivariate model, four different models are introduced utilizing a conditional specification approach, a conditional survival function approach, and an Arnold–Ng bivariate beta distribution construction approach. Distributional properties for such bivariate distributions are investigated. Parameter estimation strategies for the models are discussed, as are the consequences of fitting two of the models to a particular data set involving the proportion of foggy days at two different airports in Colombia. 相似文献
