Do downward private transfers enhance maternal labor supply? Evidence from around Europe 总被引:1,自引:1,他引:0
Using data on 2,317 mother–daughter pairs from 10 European countries, we investigate the impact of downward time and monetary
transfers on the career choices of transfer-receiving young mothers. For Europe as a whole, we find a strong positive effect
of grandchild care on the labor force participation and the degree of labor market involvement of the young mother, but no
impact of monetary transfers on either of these decisions. Both recipients and donors with better endowments are more likely
to participate in a monetary transaction, while mothers with lower level of human capital are more likely to provide time
transfers to their better endowed daughters. 相似文献

Pathways to bystander responses were examined in both generalized and bias-based bullying incidents involving immigrant-origin victims. Participants were 168 (Mage = 14.54, 57% female) adolescents of immigrant (37.5%) and nonimmigrant backgrounds, who responded to their likelihood of intervening on behalf of either an Arab or Latine victim. Models tested whether contact with immigrants and one's desires for social contact with immigrant-origin peers mediated the effects of individual (shared immigrant background, and discriminatory tendencies) and situational (inclusive peer norms) intergroup factors on active bystander responses. Findings indicated that desires for social contact reliably mediated effects across both victims; however, contact with immigrant peers was only associated with responses to Latine victims. Implications for how to promote bystander intervention are discussed. 相似文献

With globalization and increased international competition have come more flexible forms of employment and increased job insecurity. The authors address the impact of perceived job insecurity on employees' work attitudes and intentions. After reviewing relevant research on stress theory and the relationship between job insecurity and its consequences, they test two hypotheses on 942 employees in Spain, namely: first, that job insecurity relates negatively to job satisfaction and organizational commitment and positively to intention to leave; and, second, that job insecurity, economic need and employability interact in the prediction of these outcomes. 相似文献

We aimed to explore the association between age of onset of gambling problems and current psychopathological and clinical
status, personality profile and therapeutic outcome in a sample of pathological gamblers. A total of 904 consecutive pathological
gambling patients were administered several instruments about gambling behavior, psychopathology and personality. They received
a 4-month cognitive-behavioral group treatment. Information of dropouts and relapses during treatment was registered. Older
age of onset of gambling problems was associated with higher general psychopathology (SCL-90-R Paranoid Ideation, Psychoticism,
Depression; P < 0.015). Younger age of onset was related to greater severity of pathological gambling (P < 0.015), higher novelty seeking, and lower self-directedness (P < 0.015). No statistically significant association was found between age of onset and relapse and dropouts during treatment.
Age of onset of gambling problems seems to influence the clinical presentation of pathological gambling but not treatment
outcome. 相似文献

Two-tailed asymptotic inferences for a proportion 总被引:1,自引:0,他引:1
This paper evaluates 29 methods for obtaining a two-sided confidence interval for a binomial proportion (16 of which are new proposals) and comes to the conclusion that: Wilson's classic method is only optimal for a confidence of 99%, although generally it can be applied when n≥50; for a confidence of 95% or 90%, the optimal method is the one based on the arcsine transformation (when this is applied to the data incremented by 0.5), which behaves in a very similar manner to Jeffreys’ Bayesian method. A simpler option, though not so good as those just mentioned, is the classic-adjusted Wald method of Agresti and Coull. 相似文献

In this article a generalized Frank copula was selected to model the dependence between the energy on two frequency bands of the speech signal, coming from eight languages. An algorithm was developed that uses maximum likelihood to choose the best fitting copula’s parameters. Through bootstrap, the algorithm estimates the variability of the parameters for each language and also computes confidence regions by means of Voronoi tesselations. A linguistic conjecture which claims that the languages are organized in three rhythmic classes, was confirmed by the Voronoi regions. Modeling with a uniparametric Frank copula, the different degrees of dependence between the energies were quantified. 相似文献

We investigate local influence analysis in functional comparative calibration models with replicated data. A method for selecting appropriate perturbation schemes based on the expected Fisher information matrix with respect to the perturbation vector is proposed. It is shown that arbitrarily perturbing these models may result in misleading inference about the influential subjects. First-order influence measures for identifying the correct influential subjects and replicates on corrected score estimators are defined. We introduce different perturbation schemes including perturbation of subjects and replicates on the corrected likelihood function and obtain the density of the perturbed model from which the methodology is based. Particularly, three perturbation of variances schemes could be a better way to handle badly modeled subjects or replicates. Two real data sets are analyzed to illustrate the use of our local influence measures. 相似文献

In this work we derive closed form expressions for the probability density functions and moments of the quotient and product of the components of the bivariate generalized exponential distribution introduced by Kundu and Gupta (J Multivariate Anal, 100:581–593, 2009) and compute the percentage points. The derivations will be useful for practitioners of this bivariate model. We then give a real data application of the product. 相似文献

This paper suggests a new explanation for the low level of annuitization, which is valid even if one assumes perfect markets. We show that, as soon there is a positive bequest motive, sufficiently risk averse individuals should not purchase annuities. A model calibration accounting for lifetime risk aversion generates a significantly smaller willingness-to-pay for annuities than the one generated by a standard time-additive model. Moreover, the calibration predicts that riskless savings finance one third of consumption, in line with empirical findings. 相似文献
