Childcare arrangements are key in women’s ability to juggle motherhood and work outside the home. As such, the study of access to childcare and its use is of great policy relevance. We focus on a particular kind of informal childcare, the one provided by grandparents. Empirically, assessing the effect of grandparental childcare is not an easy task due to unobserved preferences. In light of the potential outcome framework, we interpret the biases resulting from unobserved preferences as arising from the non-compliance of mothers to the availability of grandparents and from preferences of grandparents for activities other than childcare. Using an instrumental variable approach on Italian data, we find that the effect of grandparental childcare on mothers’ labour supply is positive, statistically significant and economically relevant. The effect is stronger for less educated mothers, with young children and living in northern and central Italy. 相似文献

This is a multicenter cross-sectional study where we aimed to detect the rate of osteopenia/osteoporosis in an HIV female population (WLWHIV) by means of “heel quantitative ultrasound” (QUS) measurement. We enrolled 273 patients, mean age 48.1 years, 36% menopausal, 96% on combination antiretroviral therapy (cART). Calcaneal measure of bone mass index by QUS revealed osteopenia and osteoporosis in 76 (27.8%) and 16 (5.9%) WLWHIV. Our data underline the correlation between low QUS parameters and traditional risk factors for osteoporosis rather than with cART exposure, thus suggesting the crucial importance of detection and correction of traditional risk factors for osteoporosis in WLWHIV. 相似文献

Abstract Globalization, variation in customer expectations, and the developments connected to Information & Communication Technology are usually considered as the main drivers of changes in Operations Management (OM) strategies by firms in both manufacturing and service industries. Emerging digital technologies, such as Internet of Things or Cloud Computing, represents a novel paradigm that is rapidly affecting on several aspects of everyday-life of private and business users. This paper contributes to extant literature about the relationship between emerging digital technologies and OM, by stressing the value co-creation issue. Specifically, we investigate how emerging digital technologies affect OM through value co-creation in the maritime industry. Our study reports the case of FairWind project, an open technology marine service and graphic user interface enabling sailors to personalize their experience on board through 3rd party boat applications. The case of Fair Wind points out how emerging digital technologies contribute to OM within both organizations and, more in general, maritime industry, as well as the critical role of user’s co-creation in defining and managing on-board operations. 相似文献

This paper investigates the role of the extended parental leave in the return to work for mothers of newborn children. Exploiting
the variability in policies offered by the European countries, the paper studies the influence of statutory leave characteristics—length
of the job-protection and payments during the leave-period—on the hazard of returning to work at different ages of the child.
Results suggest that longer periods of job-protection increase the hazard of returning to work; on the other hand, providing
paid leaves increases the probability of remaining at home during the first year of life of the child. 相似文献

More educated parents are observed to have better educated children. However, previous research has found conflicting results
regarding the role of fathers and mothers: in most cases, a strong positive paternal effect was found with a negligible maternal
effect; in fewer cases, opposite results were found. In this paper, I use a sample of Norwegian twins to evaluate the impact
of sample size and sample selection on the estimates’ robustness: results concerning the effect of mother’s education are
very sensitive to the sample size, while the selection of the sample seems to be a key to reconciling previous results. 相似文献

In this paper some results on the computation of optimal designs for discriminating between nonlinear models are provided. In particular, some typical deviations of the Michaelis–Menten model are considered. A common deviation of this pharmacokinetic model consists on adding a linear term. If two linear models differ in one parameter the T-optimal design for discriminating between them is c-optimal for estimating the added linear term. This is not the case for nonlinear models. 相似文献

The Fay-Herriot area-level model for correlated response data is augmented with a between-groups-of-domains effect. Correlated-response parameters of small-area estimates no longer need the assumption of spatial contiguity. A simulation shows that area-level correlated-response observations increase the efficiency of the estimates, but do not reduce the biases. 相似文献

The present work explores whether self-objectification triggered by doing peculiar work activities would increase people’s conforming behavior. We conducted an experimental study in which participants (N = 140) were asked to perform a high objectifying activity (vs. low objectifying activity vs. baseline condition) simulating a real computer job. Afterwards, their levels of self-objectification and conforming behavior were assessed. Results revealed that participants who performed the high objectifying activity self-objectified (i.e., perceived themselves as lacking human mental states) more than the other conditions and, in turn, conformed more to the judgments of unknown similar others. Crucially, increased self-objectification mediated the effects of the high objectifying activity on enhancing conforming behavior. Theoretical and applied implications of these findings are discussed. 相似文献

Evidence suggests that the increasing life expectancy levels at birth witnessed over the past centuries are associated with a decreasing concentration of the survival times. The purpose of this work is to study the relationships that exist between longevity and concentration measures for some regression models for the evolution of survival. In particular, we study a family of survival models that can be used to capture the observed trends in longevity and concentration over time. The parametric family of log-scale-location models is shown to allow for modeling different trends of expected value and concentration of survival times. An extension towards mixture models is also described in order to take into account scenarios where a fraction of the population experiences short term survival. Some results are also presented for such framework. The use of both the log-scale-location family and the mixture model is illustrated through an application to period life tables from the Human Mortality Database. 相似文献
