How do changes in employment uncertainty matter for fertility? Empirical studies on the impact of employment uncertainty on reproductive decision-making offer a variety of conclusions, ranging from gender and socio-economic differences in the effect of employment uncertainty on fertility intentions and behaviour, to the effect of employment on changes in fertility intentions. This article analyses the association between a change in subjective employment uncertainty and fertility intentions and behaviour by distinguishing male and female partners’ employment uncertainty, and examines the variation in these associations by education. Using a sample of men and women living in a couple from the Swiss Household Panel (SHP 2002–2011), we examine through multinomial analysis how changes in employment uncertainty and selected socio-demographic factors are related to individual childbearing decisions. Our results show strong gendered effects of changes in employment uncertainty on the revision of reproductive decisions among the highly educated population. 相似文献

In recent years, researchers have become increasingly interested in how the effects of parental separation on children’s educational attainment vary with social background. On the one hand, parents with more resources might be better able to prevent possible adverse events like separation to affect their children’s outcomes. On the other hand, children from higher social backgrounds might have more resources to lose from a parental separation. A wide range of empirical studies on the issue have come to inconsistent conclusions, with support found for both perspectives. The aim of this paper is to monitor the influence of methodological and operational choices on the different results observed across studies. We focus on aspects such as the operationalization of key variables, the measurement of inequality in absolute and relative terms and the different strategies used to address endogeneity. We study the effects of parental separation on educational attainment for a cohort of British children born in 1970 and find that conclusions change depending on whether social background is measured using the mother’s or father’s characteristics and whether relative or absolute differences between groups are considered. Results are relatively insensitive to the operationalization of dependent variables and the treatment of missing data. When using data from Understanding Society instead of the British Cohort Study, results also did not change. We reflect on how these findings can explain the contradictory results from earlier studies on the topic, and how heterogeneity in the effects of parental separation by socio-economic background should be interpreted. 相似文献

The spatial organization of 1,020 groups comprised of adolescents and young adults, observed in an ecological setting while
walking, was analyzed. Observations were made in an urban environment where walking speed could be considered. The results
showed that male dyads and triads tended to walk abreast less often than female dyads. Mixed dyads walked abreast more often
than same-sex dyads; and the males preceded the females in two-thirds of the cases. The male groups walked at a higher rate
of speed than the female groups. Walking speed was correlated to misalignment between group members when walking. The most
frequent spatial arrangement in triads was a “<” formation (as seen from above, while the walking direction was from left
to right), with the middle individual positioned slightly behind in comparison to the lateral individuals. Groups comprised
of more than three individuals tended to split themselves into single individuals, dyads, and triads. 相似文献

We deal with the ranking problem of the nodes in a directed graph. The bilateral relationships specified by a directed graph
may reflect the outcomes of a sport competition, the mutual reference structure between websites, or a group preference structure
over alternatives. We introduce a class of scoring methods for directed graphs, indexed by a single nonnegative parameter
α. This parameter reflects the internal slackening of a node within an underlying iterative process. The class of so-called
internal slackening scoring methods, denoted by λ
α
, consists of the limits of these processes. It is seen that λ0 extends the invariant scoring method, while λ
∞
extends the fair bets scoring method. Method λ1 corresponds with the existing λ-scoring method of Borm et al. (Ann Oper Res 109(1):61–75, 2002) and can be seen as a compromise between λ0 and λ
∞
. In particular, an explicit proportionality relation between λ
α
and λ1 is derived. Moreover, the internal slackening scoring methods are applied to the setting of social choice situations where
they give rise to a class of social choice correspondences that refine both the Top cycle correspondence and the Uncovered
set correspondence. 相似文献

Maximum likelihood (ML) estimation of relative risks via log-binomial regression requires a restricted parameter space. Computation via non linear programming is simple to implement and has high convergence rate. We show that the optimization problem is well posed (convex domain and convex objective) and provide a variance formula along with a methodology for obtaining standard errors and prediction intervals which account for estimates on the boundary of the parameter space. We performed simulations under several scenarios already used in the literature in order to assess the performance of ML and of two other common estimation methods. 相似文献

We design a double-or-quits game to compare the speed of learning one’s specific ability with the speed of rising confidence as the task gets increasingly difficult. We find that people on average learn to be overconfident faster than they learn their true ability and we present an intuitive-Bayesian model of confidence which integrates confidence biases and learning. Uncertainty about one’s true ability to perform a task in isolation can be responsible for large and stable confidence biases, namely limited discrimination, the hard–easy effect, the Dunning–Kruger effect, conservative learning from experience and the overprecision phenomenon (without underprecision) if subjects act as Bayesian learners who rely only on sequentially perceived performance cues and contrarian illusory signals induced by doubt. Moreover, these biases are likely to persist since the Bayesian aggregation of past information consolidates the accumulation of errors and the perception of contrarian illusory signals generates conservatism and under-reaction to events. Taken together, these two features may explain why intuitive Bayesians make systematically wrong predictions of their own performance. 相似文献

AbstractIn recent years there has been a great deal of social and legislative progress in the struggle against discrimination on grounds of sexual orientation. However, the coming out process in the workplace is still a crucial aspect in the lives of many lesbians and gays (LG). This study sets out to analyse the different strategies that Spanish LG adopt when revealing their sexual orientation at work by identifying the factors that facilitate or hinder this process. It also analyses the personal and organizational consequences of the strategies used in the coming out process. The study was carried out through in-depth interviews with 15 LG. Results show that the coming out strategies vary and are affected by different factors (e.g., characteristics of the colleagues, sector, etc.). Moreover, it confirmed that the coming out process (or its absence) can have consequences at different levels (e.g., relationships with colleagues, perception of organizational injustice, etc.). 相似文献
