Abstract Extract I have suggested that at a given birth order the probability of having a further pregnancy is greater when the last pregnancy had been spontaneously aborted than when it resulted in a birth.(2) Léridon,(3)in the course of a valuable paper on foetal wastage, presents data which, according to him, impugn my suggestion. I would like to question his claim. 相似文献

Functional Capacity Evaluations (FCE's) are part of practice in work injury prevention and rehabilitation, and are designed to define an individual's functional abilities or limitations in the context of safe, productive work tasks. Qualitative research methodology was used to investigate the attitudes and behaviours of health professionals in relation to FCE use. The study aimed to identify why health professionals chose a particular FCE, and to identify what factors influence health professionals' clinical judgements when providing results and recommendations for the individual being assessed. Five health professionals from the Hunter Region of New South Wales, Australia, participated in semi-structured, individual interviews using a phenomenological approach. Following inductive analysis of the data, four themes reflecting participants' attitudes and behaviours of FCE use emerged: i) referrals and expectations, including why and when the assessment is completed ii) outcomes, -- what the results aim to provide iii) workplace/practice/usage issues and iv) skills of the assessor. The results indicate the need for further research on the clinical utility of FCE's. A large scale quantitative study would allow results to be generalised to a wider community of FCE users. 相似文献

Abstract Published data are reviewed and it is concluded that about one fertilized ovum in three perishes before pregnancy is recognised. Of those surviving until pregnancy is recognized, one in four or five perish before term. So spontaneous loss accounts for about one fertilized ovum in two in a medically advanced society. 相似文献

This paper explores women's and men's work orientations in conditions of job insecurity, arguing that it is time to move beyond essentalist conceptions of work orientations and central life interests in order to understand the significance of paid work in people's lives. Data from a qualitative study are presented which show that the significance of paid work and the priority given to home and work are affected by experiences of job insecurity, changing domestic circumstances and stage in the life cycle and that this is the case for both women and men. Conversely, the significance of paid work can affect how job insecurity is experienced and its impact on individuals and their families. The assumption that men's work orientations are homogeneous and that work is their central life interest is not supported by the findings presented here and it is argued that the significance of work in men's and women's lives is more variable than has hitherto been recognized. To capture this variability it is time to move away from the acrimony of the debate over women's work orientations and notions of a central life interest which underpin it. 相似文献

Using the data from the AIDS Link to Intravenous Experiences cohort study as an example, an informative censoring model was
used to characterize the repeated hospitalization process of a group of patients. Under the informative censoring assumption,
the estimators of the baseline rate function and the regression parameters were shown to be related to a latent variable.
Hence, it becomes impractical to directly estimate the unknown quantities in the moments of the estimators for the bandwidth
selection of a smoothing estimator and the construction of confidence intervals, which are respectively based on the asymptotic
mean squared errors and the asymptotic distributions of the estimators. To overcome these difficulties, we develop a random
weighted bootstrap procedure to select appropriate bandwidths and to construct approximated confidence intervals. One can
see that our method is simple and faster to implement from a practical point of view, and is at least as accurate as other
bootstrap methods. In this article, it is shown that the proposed method is useful through the performance of a Monte Carlo
simulation. An application of our procedure is also illustrated by a recurrent event sample of intravenous drug users for
inpatient cares over time. 相似文献
