Une synthèse est faite des développements théoriques et des applications récentes en matière de relations générales liant structure et mouvement dans les populations ouvertes non stables. Bien que ces relations généralisent heureusement les équations établies par Lotka, leur utilité pratique n'est pas toujours évidente. D'abord, il ságit le plus souvent d'identités comptables qui ne fournissent pas nécessairement de meilleurs résultats que le calcul direct. Ensuite, ces techniques utilisent les taux d'accroissement des effectifs par âge, qui sont difficiles à évaluer correctement à partir de statistiques déficientes.The article presents an overview of current developments and applications in generalized stable population (or r-variable) theory. Though these general relations aptly extend Lotka's formulations, their practical advantages are not always clear. Firstly, most of these relations are tautological and do not in this case improve upon the more usual methods of calculation. Secondly, applications rely on intercensal estimation of growth rates by age, which are often biased due to defective data. 相似文献

Effect of Sociocultural Context and Parenting Style on Scholastic Achievement among Iranian Adolescents 总被引:1,自引:0,他引:1

School grades, family demographics and responses to the parental authority questionnaire were assessed in 240 eighth‐grade students in the southern, central and northern parts of Tehran, Iran's capital. The result showed that poorer families with traditional values had more authoritarian attitudes toward parenting than richer families with more modern values. In contrast to the studies conducted in East Asian societies, the current study found that authoritative parenting was the style associated with the highest academic outcome. Tests of mediation and moderation effects showed that the relation between parenting style and academic outcome was independent of sociocultural context. 相似文献

Suffering at work has become a major social phenomena. This situation has many causes: high performance enhancement, urgency seen as an obligation, pressure for results, but also fear, and the soaring of ‘the battle for places’ (la lutte des places). The psychopathological consequences of pressure at work are now well known: breakdowns, professional exhaustion, work addiction, burnout, harassment. Stress has become an ordinary tool for management. Employees cannot find a meaning to this context, nor can they identify the causes of their ill being or the reasons for the violence they endure. They confront an opaque and paradoxical power. Looking for solutions to the contradictions to which management has given rise without resolving, they become responsible for those difficulties and guilty of their own suffering. These are ‘innocent violences’ in so far as they are justified by an indisputable system of management. 相似文献

A deterministic model of BSE transmission is used to calculate the R(0) values for specific years of the BSE epidemics in the United Kingdom (UK), the Netherlands (NL), and Switzerland (CH). In all three countries, the R(0) values decreased below 1 after the introduction of a ban on feeding meat and bone meal (MBM) to ruminants around the 1990s. A variety of additional measures against BSE led to further decrease of R(0) to about 0.06 in the years around 1998. The calculated R(0) values were consistent with the observations made on the surveillance results for UK, but were partially conflicting with the surveillance results for NL and CH. There was evidence for a dependency of the BSE epidemic in NL and CH from an infection source not considered in the deterministic transmission model. Imports of MBM and feed components can be an explanation for this discrepancy, and the importance of imports for these observations is discussed. 相似文献

Starting with longitudinal data on two cohorts of women living in the Alpes-Maritimes in 1982 (a sample of 1,500 women in total) we try to establish the role of the spatial distribution of opportunities at a number of key stages in the life cycle: marriage, birth of first child, making professional use of qualifications, confrontation of a situation of professional risk and professional mobility during the years immediately following the completion of studies. The underlying hypothesis is that control of social location often depends on the control of spatial location. 相似文献

This article presents theoretical elements concerning the ‘nature versus culture’ confrontation as a particular aspect of the worldwide expansion of Western civilization. Several speculations are made concerning the philosophical foundations which have provided the base for the current political and economic mega-scenarios in the contemporary world. We turn our attention to the articulations of the concept of nature with the processes of mondialization of Western culture and with the history of universal culture. Finally, several considerations are made on the dynamics of economic processes on a world scale and projections on the impact of science and technology in the social and political frames that are taking place in the contemporary world. 相似文献

We characterize two different approaches to the idea of equality of opportunity. Roemer’s social ordering is motivated by
a concern to compensate for the effects of certain (non-responsibility) factors on outcomes. Van de gaer’s social ordering
is concerned with the equalization of the opportunity sets to which people have access. We show how different invariance axioms
open the possibility to go beyond the simple additive specification implied by both rules. This offers scope for a broader
interpretation of responsibility-sensitive egalitarianism. 相似文献

Firms mitigate uncertainty in demand and supply by carrying safety stock, planning for excess capacity and diversifying supply sources. In this study, we provide a framework to jointly optimize these three levers in a periodic review infinite horizon setting, and in particular we examine how one can reduce inventory and capacity investments through proper diversification strategies. Observing that a modified base‐stock inventory policy is optimal, we find that the capacity‐diversification problem is well behaved and characterize the optimal mix of safety stock, excess capacity and extra number of supply sources. We find that higher supply uncertainty results in higher safety stock, more excess capacity, and higher diversification. But safety stock and diversification are non‐monotonic in demand uncertainty. Our results can be extended to situations in which suppliers are heterogeneous, and can be used to develop effective heuristics. 相似文献

One of the most salient social categories conveyed by human faces and voices is gender. We investigated the developmental emergence of the ability to perceive the coherence of auditory and visual attributes of gender in 6‐ and 9‐month‐old infants. Infants viewed two side‐by‐side video clips of a man and a woman singing a nursery rhyme and heard a synchronous male or female sound track. Results showed that 6‐month‐old infants did not match the audible and visible attributes of gender, and 9‐month‐old infants matched only female faces and voices. These findings indicate that the ability to perceive the multisensory coherence of gender emerges relatively late in infancy and that it reflects the greater experience that most infants have with female faces and voices. 相似文献
