The goal of this study is to give a comprehensive empirical account of push and pull factors, situated at various societal levels, which may influence people's early retirement. Factors in two contrasting European countries have been analysed and compared: Denmark, where the rate of early exit/retirement is relatively low, and The Netherlands, where this rate is relatively high. Our analysis, looking into possible explanations for the difference in rates, includes factors that operate at the macro or institutional level of the labour market and the social security system, at the meso level of firms and companies, and at the micro level of individual workers. In addition, we not only look into the effects of structural, objective factors, which impacts are usually analysed from an incentive perspective, but also into the effects of cultural factors, i.e. of preferences, attitudes and values. Cultural factors related to early exit have not been the object of much international comparison thus far, although their possible significance is readily acknowledged. The differences in retirement behaviour in Denmark and The Netherlands are explained by the fact that Danish workers, at all three levels, are less experiencing structural and cultural factors pushing them out of the labour market, as well as experiencing factors pulling them into retirement, compared to workers in The Netherlands.  相似文献

The authors of this article have developed six probabilistic causal models for critical risks in tunnel works. The details of the models' development and evaluation were reported in two earlier publications of this journal. Accordingly, as a remaining step, this article is focused on the investigation into the use of these models in a real case study project. The use of the models is challenging given the need to provide information on risks that usually are both project and context dependent. The latter is of particular concern in underground construction projects. Tunnel risks are the consequences of interactions between site‐ and project‐ specific factors. Large variations and uncertainties in ground conditions as well as project singularities give rise to particular risk factors with very specific impacts. These circumstances mean that existing risk information, gathered from previous projects, is extremely difficult to use in other projects. This article considers these issues and addresses the extent to which prior risk‐related knowledge, in the form of causal models, as the models developed for the investigation, can be used to provide useful risk information for the case study project. The identification and characterization of the causes and conditions that lead to failures and their interactions as well as their associated probabilistic information is assumed to be risk‐related knowledge in this article. It is shown that, irrespective of existing constraints on using information and knowledge from past experiences, construction risk‐related knowledge can be transferred and used from project to project in the form of comprehensive models based on probabilistic‐causal relationships. The article also shows that the developed models provide guidance as to the use of specific remedial measures by means of the identification of critical risk factors, and therefore they support risk management decisions. Similarly, a number of limitations of the models are discussed.  相似文献

The increased interest in customer service and the trend towards customization gives rise to new organizational forms such as the virtual organization. This paper introduces the Modular Network Design (MND) approach to complement Mowshowitz' (1997) theory of virtual organization. This theory focuses on metamanagement of the virtual organization and consists of four activities: (1) determine and analyze customer requirements, (2) track the possibilities for satisfying these requirements, (3) develop and allocate production tasks among the members of the virtual organization, and (4) assess and adjust tasks and allocation procedures. The MND approach elaborates on this theory by breaking down both the requirements and the production tasks into modular entities, and by measuring the performance of the resulting virtual network in terms of operating costs and throughput time. The major contribution of the MND approach lies in its ability to support the assessment of alternative allocations of production tasks among the members of a virtual organization, using Information and Communication Technology (ICT) as enabler. The assessment of such alternative designs is illustrated by an application of MND in the air cargo industry. The results show how the virtual organization and its members can realize significant improvements in operating costs and throughput times when applying ICT to link and reallocate their modular production tasks in response to customized orders.  相似文献

This two-wave multi-informant study examined the bidirectional associations of parental control and solicitation with adolescent disclosure and delinquency. Participants were 289 adolescents (150 females and 139 males, modal age 14) and both parents. Parental solicitation and control did not predict adolescent delinquency, but adolescents' self-reported disclosure was a negative predictor of delinquency. In addition, delinquency predicted less disclosure. Furthermore, maternal solicitation predicted disclosure and adolescent disclosure predicted parental solicitation. All relations held after controlling for leisure time spent with parents and with peers. These longitudinal findings show an overlap in the development of parental solicitation and the development of adolescent disclosure, but also show that only adolescent disclosure is negatively related to delinquency over time.  相似文献

Probabilistic sensitivity analysis (SA) allows to incorporate background knowledge on the considered input variables more easily than many other existing SA techniques. Incorporation of such knowledge is performed by constructing a joint density function over the input domain. However, it rarely happens that available knowledge directly and uniquely translates into such a density function. A naturally arising question is then to what extent the choice of density function determines the values of the considered sensitivity measures. In this paper we perform simulation studies to address this question. Our empirical analysis suggests some guidelines, but also cautions to practitioners in the field of probabilistic SA.  相似文献

There is a small but growing literature on the determinants of social capital. Most of these studies use a measure of trust to define social capital empirically. In this paper we use three different measures of social capital: the size of the individual’s social network, the extent of their social safety net and membership of unions or associations. A second contribution to the literature is that we analyze what social capital contributes to our well-being. Based on this, we calculate the compensating income variation of social capital. We find differences in social capital when we differentiate according to individual characteristics such as education, age, place of residence, household composition and health. Household income generally has a statistically significant effect. We find a significant effect of social capital on␣life␣satisfaction. Consequently, the compensating income variation of social capital is substantial. Thanks to Tijl Woortman for his research assistance.  相似文献

Adolescents' peer experiences embrace behavior, relationship quality, status, and victimization, but studies that account for multiple dimensions are rare. Using latent profile modeling and measures of peer behavior, relationship quality, peer status, and victimization assessed from 1,677 adolescents, four profiles were identified: High Quality, Low Quality, Low Quality Victimized, and Deviant Peers. Multinomial logistic regressions showed that negative parent–child relationships in preadolescence reduced the likelihood of High Quality peer relations in mid‐adolescence but only partly differentiated between the other three profiles. Moderation by gender was partly found with girls showing greater sensitivity to parent–child relationship quality with respect to peer experiences. Results underline the multifaceted nature of peer experiences, and practical and theoretical implications are discussed.  相似文献

The developmental interplay between identity and adjustment was examined in a seven‐wave longitudinal study of 428 European female college students (Mage=18.8 years) over a period of 3 years, with semi‐annual measurement waves each year. Latent Class Growth Analysis (LCGA) was used to identify developmental typologies of both identity formation (i.e., dimensions of commitment and exploration) and adjustment (i.e., depressive symptoms and self‐esteem). Four trajectory classes emerged for identity, three of which had been suggested earlier in the literature ( Josselson, 1996 ): Pathmakers, Guardians, and Searchers. The fourth trajectory class was labeled Consolidators and consisted of individuals characterized by a strong focus on strengthening their current identity commitments, at the expense of a thorough exploration of alternative options. Three trajectory classes were identified for adjustment: Optimal Adjustment, Moderate Adjustment, and Stable Maladjustment. Each of the four identity trajectory classes was associated with a specific profile of adjustment, with the Searchers showing the poorest profile and the Pathmakers and Consolidators the most positive profile. Practical implications and suggestions for future research are outlined.  相似文献
