Summary. The pattern of absenteeism in the downsizing process of companies is a topic in focus in economics and social science. A general question is whether employees who are frequently absent are more likely to be selected to be laid off or in contrast whether employees to be dismissed are more likely to be absent for the remaining time of their working contract. We pursue an empirical and microeconomic investigation of these theses. We analyse longitudinal data that were collected in a German company over several years. We fit a semiparametric transition model based on a mixture Poisson distribution for the days of absenteeism per month. Prediction intervals are considered and the primary focus is on the period of downsizing. The data reveal clear evidence for the hypothesis that employees who are to be laid off are more frequently absent before leaving the company. Interestingly, though, no clear evidence is seen that employees being selected to leave the company are those with a bad absenteeism profile. 相似文献

In Sweden, the initial contact between help-seeking people and a social welfare office normally takes place over the telephone, with designated intake officers handling those aiming to apply for social assistance. Citizens seeking help are here sorted according to various eligibility criteria as well as according to different intake routines. The outcome of the sorting process is that some receive an appointment for a further assessment while others are sent away. This article describes and classifies the degree of selection at seven telephone intakes, discusses relations between the degrees of selection and reasons for selection and distinguishes several selection strategies. 相似文献

Minas R. Social expenditures and public administration: are local social assistance costs in Sweden a matter of organisation?Int J Soc Welfare 2010: 19: 215–224 © 2009 The Author(s), Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. This study examines the connection between organisational factors and local social assistance expenditures in Swedish municipalities. The organisation of social assistance units, particularly those for the intake of social assistance inquirers, and the possible implications for local social assistance costs are highlighted. The study is based on interview data from medium‐sized Swedish municipalities combined with register data covering the years from 1997 to 2001. The results show that socioeconomic factors have an overall dominant effect, but also that organisational factors co‐vary with local social assistance expenditures. The results show a cost‐reducing effect for special intake units: firstly, when these units are analysed together with other forms of specialisation and secondly, when staff resources are taken into account. Thus, specialised intake organisation by itself does not play a cost‐reducing role, but does so in combination with certain other factors that characterise the internal organisation of the social welfare office. 相似文献

Age at first marriage in Malawi: a Bayesian multilevel analysis using a discrete time-to-event model 总被引:4,自引:0,他引:4

Summary. The paper presents a hierarchical discrete time survival model for the analysis of the 2000 Malawi Demographic and Health Survey data to assess the determinants of transition to marriage among women in Malawi. The model explicitly accounts for the unobserved heterogeneity by using family and community random effects with cross-level correlation structure. A nonparametric technique is used to model the base-line discrete hazard dynamically. Parameters of the model are computed by using a Markov chain Monte Carlo algorithm. The results show that rising age at marriage is a combination of birth cohort and education effects, depends considerably on the family and to some extent on the community in which a woman resides and the correlation between family and community random effects is negative. These results confirm a downward trend in teenage marriage and that raising women's education levels in sub-Saharan Africa has the beneficial effect of increasing age at marriage, and by implication reducing total fertility rates. The negative correlation between family and community random effects has policy implications in that targeting communities with an intervention to increase age at first marriage may not necessarily yield reduced fertility levels in individual families. A campaign that is geared towards individual families would achieve the desired goals. Overall, the findings point to the need for the Government in Malawi to enact public policies which are geared at vastly improving women's education at higher levels. The variation in marriage rates over families poses problems in delivering the policy, since particular policies must be devised for specific groups of families to accomplish the required social and health objectives. 相似文献

This paper addresses some of the questions raised in a debate between Deaton and Paxson, 1998, Deaton and Paxson, 2003 and Gan and Vernon (2003) in the Journal of Political Economy. At issue is what, on the basis of theory, the behaviour of households should be in relation to expenditure on food, as household size increases. One argument is that expenditure on food, per capita, should increase as household size increases, but analysis of the data gives very different results. Questions arise as to whether food is a public or private good within households, how food compares to clothing and whether there can be substitution away from food, for example towards clothing.For the purposes of addressing these and related questions in the Cyprus context, a household budget survey was undertaken, in which 625 responses were obtained. The paper describes the survey and uses the results of the survey to run regressions to identify the variables that relate significantly to expenditure on food. What we add to the discussion is the analysis of the determinants of expenditure on food in Cyprus, and the categorisation of this expenditure into food at home, take-away food, food in pubs and cafes, and food in restaurants. Our results tend to support Gan and Vernon (2003); we find, for example, that clothing is more private than food. 相似文献

This study challenges the prevailing view that marital companionship promotes marital satisfaction. By following a cohort of married couples for over a decade and by incorporating several methodological improvements—such as refining the measurement of marital satisfaction, determining how much spouses enjoy doing the leisure activities they pursue together and apart, and using diary data to portray marital leisure patterns—we found that the association between companionship and satisfaction is less robust than previously believed, and that it depends on how often spouses pursue activities that reflect their own and their partner's leisure preferences. Over time, involvement in leisure liked by husbands but disliked by wives, whether as a couple or by husbands alone, is both a cause and a consequence of wives' dissatisfaction. 相似文献

Various nonparametric approaches for Bayesian spectral density estimation of stationary time series have been suggested in the literature, mostly based on the Whittle likelihood approximation. A generalization of this approximation involving a nonparametric correction of a parametric likelihood has been proposed in the literature with a proof of posterior consistency for spectral density estimation in combination with the Bernstein–Dirichlet process prior for Gaussian time series. In this article, we will extend the posterior consistency result to non-Gaussian time series by employing a general consistency theorem for dependent data and misspecified models. As a special case, posterior consistency for the spectral density under the Whittle likelihood is also extended to non-Gaussian time series. Small sample properties of this approach are illustrated with several examples of non-Gaussian time series. 相似文献

The aims of this study were (1) to analyze the sport participation in a cohort of community-dwelling elderly people in Germany and (2) to evaluate associations between sport participation, sociodemographic factors, cardiovascular risk factors, and health status. In a monitored prospective cohort study (getABI), 6,880 unselected patients ≥65 years have been followed up by 344 general practitioners beginning in 2001. As part of the 5-year follow-up telephone interview, a sample of 1,376 participants was interviewed on sport participation. The association between participation in at least one sporting activity (“sporty” yes/no) during the past week (cycling) or month (other sports) and the following parameters was analyzed by logistic regression: age, sex, immigration background, education, waist circumference, smoking, self-reported health, history of vascular events, diabetes mellitus, lipometabolic disorder, and arterial hypertension. Analysis of activities (n = 1,304; median age 76 (70–94) years; 55.1% women) showed that 27.6% of participants rode a bicycle during the previous week. During the previous month, 24.9% of participants did gymnastics or strength training, and 16.5% swam. Of all participants, 53.8% were sporty. Multivariate analysis revealed several independent factors to be associated with being sporty (p < 0.05): younger age, male sex, higher education, nonsmoking, better self-reported health, and not being diagnosed with diabetes. Immigration background, waist circumference, history of vascular events, lipometabolic disorder, and hypertension did not show a statistically significant association (p ≥ 0.05) with sport participation. Summing up, the most frequently performed sporting activities were cycling, gymnastics or strength training, and swimming. Sport participation was associated with, for example, age and sex. 相似文献
