The patterns of family formation and fertility behavior of Turkish and Moroccan women in Belgium are changing rapidly. The census data (1991) indicate a fertility decline. The reasons are changes in the nuptiality patterns, contraceptive behavior, and migratory flows. The changes are not identical in both communities. Young cohorts postpone their marriage, but this is most prominent among Moroccan women. On the other hand, young Turkish women have a clear preference for smaller families. The changes also differentiate according to migrant "generation" and level of education. The changes are not restricted to Belgium but are also observed in the countries of origin. 相似文献

AbstractThis paper aims at examining the trends, challenges and theoretical gaps in the implementation of Healthcare 4.0 (H4.0) based on a scoping review of the literature. For that, we searched journal articles in four widely known databases and screened the retrieved articles to obtain a publications’ portfolio. Our findings indicate that, despite the recency of the subject, research in H4.0 has been conducted in an interdisciplinary way with a diversified set of applications and functionalities. In terms of its implementation, H4.0 has been more commonly found in hospitals’ information flows, especially the ones related to healthcare treatments. The identified implementation trends, however, neglect a more holistic approach for H4.0, which originated three main research directions for this topic. Although identified as a trending topic in the area of healthcare operations management, literature on H4.0 may be viewed as randomly conceived, lacking academic alignment and practical orientation based on a grounded theory, which we aim at providing with the present study. 相似文献

This article addresses issues involved in the treatment of fathers who do not have custody of their children. It reviews literature on demographic trends and discusses fathers' reactions to loss of child custody. Assessment and treatment guidelines are offered so that clinical practice may become more responsive to the needs of the population. Gender concerns, particularly as they relate to transference and countertransference, are also discussed. 相似文献

Trust is a prominent determinant of effective interpersonal relationships, group process, and organizational development. However, for leaders and managers, trust building is often problematic. The aim of this article is to contribute to a growing understanding of the way in which individual managers can develop trust in organizations, particularly those defined by medium to high risk. The article presents a theoretical and empirical analysis of the nature of trust at work. Building on the results of an earlier study, use is made of the facet-theoretical approach to generate a definitional framework of trust, which focuses on the characteristics of the trusted person that contribute to the development of trust. Using items developed on the basis of a mapping sentence, hypotheses regarding the relations between the definitional framework and empirical observations were tested through smallest space analysis (SSA) of data collected from a sample of 398 bank and hospital employees. The results demonstrate strong support for the definitional system and show a clear association with results of prior research that identify perceptions of ability, integrity, fairness, and openness as key determinants of trust. The empirical structure clearly reflects the attitudinal nature of interpersonal trust at work and the items empirically distinguish distinct character-based components of trust. 相似文献

Although male sexual abuse has co-existed with female sexual abuse, the professional literature has paid minimal attention to the impact of sexual abuse of male children to their adult adaptation. This paper concentrates on the negative impact of sexual abuse on the adult male's gender identity. Examples of eight male clients' responses to sexual abuse in their adult life and the therapeutic framework utilized to work with them are discussed in the paper.This paper was originally presented at the ICAPP conference, 1993.He teaches advanced clinical practice, Human Behavior and AIDS ELECTIVE. He maintains a private practice specializing in Gay men, persons with HIV virus. 相似文献

The selection of an appropriate subset of explanatory variables to use in a linear regression model is an important aspect of a statistical analysis. Classical stepwise regression is often used with this aim but it could be invalidated by a few outlying observations. In this paper, we introduce a robust F-test and a robust stepwise regression procedure based on weighted likelihood in order to achieve robustness against the presence of outliers. The introduced methodology is asymptotically equivalent to the classical one when no contamination is present. Some examples and simulation are presented. 相似文献
