Many social scientists argue that the precarious future of post‐socialist societies is determined by cultural constraints to which the actors of transformation are exposed. In contrast to this approach, the paper focuses on those developmental obstacles which are inherent to the structure of post‐socialist societies. The analysis draws primarily on social systems theory, especially on the theory of functional differentiation. In the first part, the changing role of political actors is dealt with. The competitive nature of the democratic political process have forced the new and old political actors to adopt a pragmatic and professional attitude towards their activity. Not all of them, however, have been able to adapt to the new rules of the political game. Adaptation problems are mostly faced by those political actors who played a decisive role in the initial stages of democratization on the basis of their informal political influence. The second part of the paper focuses on the changes related to the societal functions of the democratic political system. Irrespective of the ambitions of political actors, democratic politics is inherently ‘unsuitable’ for the extensive regulation of society. A democratic political system presupposes a relatively high ability of other societal subsystems to rely on self‐regulation. The absence of this ability is an important source of systemic tensions in post‐socialist societies. These two sets of changes can be characterized as the double disenchantment of politics. Both on the systemic level and on the level of actors politics has lost many attributes of a ‘privileged’ societal activity. But the process of disenchantment can give rise to demands for a revival of the politics of ‘great deeds’.  相似文献

The interpretation of age-specific changes in hazards, relative risks, genetic parameters and other indicators of aging calculated from data on related individuals should take into account the regularities of bivariate selection. Due to such selection the hazard rate calculated for twins who have survived to a certain age may be lower than for singletons, even if marginal chances of survival for all individuals are the same. In a mixed population of relatives the proportion of pairs with closer family links increases with age, even if all marginal individual chances of survival are the same. The proportion of chronic conditions for MZ twins observed in a cross-sectional study may be different from that of DZ twins. The age-dependence of relative risks calculated in genetic-epidemiological studies of twins does not necessarily reflect changes in genetic influence on individual susceptibility to disease and death during the aging process. The age-related changes in heritability of susceptibility estimated in twin studies may have nothing to do with changes in the genetic determination of diseases with age. These issues are illustrated by empirical graphs together with the results of modeling and statistical analysis.  相似文献

Presence of growth after traumatic events was introduced to the academic community about a decade ago (Tedeschi & Calhoun, 1995). From the conventionally neglected perspective of Chinese widowers, this paper reports seventeen Chinese widowers' views on growth after conjugal loss. Findings seem to suggest that Chinese widowers would define growth as human learning, a definition probably influenced by Confucian teachings. Furthermore, contrary to claims made by Tedeschi and Calhoun (2004), it was found that growth may occur for some individuals without the presence of distress if the individuals have either a stable philosophy of life and death or optimism to buffer their distress or a sense of responsibility to suppress their distress.  相似文献

In this paper we discuss an approach to the analysis of mortality and longevity limits when survival data on related individuals with and without observed covariates are available. The approach combines the ideas of demography and survival analysis with methods of quantitative genetics and genetic epidemiology. It allows us to analyze the genetic structure of frailty in the Cox-type hazard model with random effects. We demonstrate the implementation of this strategy to survival data on Danish twins. We then evaluate the resulting lower bounds for biological limits of human longevity. Finally, we discuss the limitations of this approach and directions of further research.  相似文献

People lie on a frequent basis. However, when a victim of maltreatment lies by denying the abuse, lies can become forensically relevant. We have reviewed the relevant literature on the prevalence and memory consequences of such false denials. The way forensic interviewers proceed in the face of denying children will be shaped by their beliefs about the frequency with which truly abused children deny abuse. We discuss that estimates of the prevalence of false denials among abused children vary but that such false denials do happen. When falsely denying children eventually come forward with their experiences, a second issue lingers: how valid are maltreated children's statements after a false denial? We review the literature indicating that false denials can negatively affect memory for the investigative interview during which the lie was told. Yet, memory for the denied experience itself seems to be mostly preserved, and some research even found potential protective effects of false denials. We conclude that denials should always be handled with care in the court room, since the ground truth usually is not known, but that statements should not be dismissed based solely on previous denials.  相似文献
