This study used two waves of data to investigate pathways through which adolescents' response inhibition related to later externalizing problems. A polygenic risk score indexed genetic risk for poor response inhibition. Adolescents' performance on a response inhibition task mediated the relation between adolescents' polygenic risk scores and mother's inconsistent parenting (i.e., evocative rGE), even after controlling for mothers' genetic risk (i.e., passive rGE). Mothers' inconsistent parenting subsequently prospectively predicted adolescents' externalizing problems. Adolescents' response inhibition also prospectively predicted later externalizing behaviors. These findings were subgroup‐specific, with greater risk for non‐Hispanic Caucasian boys with substance‐disordered parents. Results suggest that poor response inhibition may increase risk for adolescents' externalizing problems both directly and by evoking certain environmental conditions.  相似文献

This article examines the issue of children with a disability who are 'informally integrated' into mainstream school. Its main purpose is to reflect the views and experiences of parents, and to identify the major difficulties that arise and their suggestions for ameliorating the situation. The data is based on a series of interviews and focus groups of parents. In order to provide a balanced perspective, responses of schools to a questionnaire were also included. Teachers were asked to express their views about integrated education. These responses were then categorised. It was found that lack of resources and training predominated.  相似文献

This paper examines the expectations of very young adults (age 18) and their mothers about financial support that parents might provide under a variety of situations common in young adulthood. Using representative data from women and one of their children, we examine differences in expectations between mothers and children and model variation in these expectations. We find that a lower proportion of mothers expect to provide support than their children expect them to, with particularly large gaps between mothers and sons. Further, there are substantial differences in support priorities. Many mothers would support only a married child and others only an unmarried one; similarly, some mothers would support only an unmarried child at home, whereas many others would only support a child away. Although some of these differences reflect differences in resources, most suggest disagreements and confusion about Americans' family values.  相似文献

Research on changes in women's parenting has focused primarily on their increased likelihood of combining parenthood with paid employment, exploring the pressures that result from this "second shift" or "double burden." This article complements this approach by focusing instead on the likely reduction in the help that mothers of small children have received as declines both in fertility and the coresidence of nonnuclear adults have reduced the number of other women in the household. Using national census data for the period 1880 to 2000, we show a substantial decline in the presence and availability of other females in the household, as fewer are coresident and more of those who are coresident are employed or in school. Although all mothers experience this decline, it is most acute for mothers working for pay in nonagricultural activities.  相似文献

The authors argue that relationship marketing can readily be adopted by a small entrepreneurial business but it will need to be adapted to the entrepreneurial environment into which it is introduced. Results from initial research suggest that entrepreneurial enterprises employ relationship marketing more effectively than less entrepreneurial organisations and they derive commercial benefits such as higher growth rates and fewer customer defections. The authors argue that entrepreneurship can be learned and so less entrepreneurial firms have the potential to learn from more successful entrepreneurs. They offer some specific recommendations but they recognise that the task is not easy because the SME has to create an internal culture that is capable of both embracing relationship marketing and being alert to opportunity.  相似文献

Sustainable urban water systems are likely to be hybrids of centralized and decentralized infrastructure, managed as an integrated system in water‐sensitive cities. The technology for many of these systems is available. However, social and institutional barriers, which can be understood as deeply embedded risk perceptions, have impeded their implementation. Risk perceptions within the water sector are often unrecognized or unacknowledged, despite their role in risk management generally in informing value judgments and specifically in ranking risks to achieve management objectives. There has been very little examination of the role of these risk perceptions in advancing more sustainable water supply management through the adoption of alternative sources. To address this gap, this article presents a framework that can be used as a tool for understanding risk perceptions. The framework is built on the relational theory of risk and presents the range of human phenomena that might influence the perception of an “object at risk” in relation to a “risk object.” It has been synthesized from a critical review of theoretical, conceptual, and empirical studies of perception broadly and risk perception specifically, and interpreted in relation to water practitioners. For a water practitioner, the risk object might be an alternative water system, a component, a process, or a technology, and the object at risk could be public or environmental health, profitability, or professional reputation. This framework has two important functions: to allow practitioners to understand their own and others’ risk perceptions, which might differ, and to inform further empirical research.  相似文献

This paper considers aspects of the theory and practice of e-learning communities. To date much of the research and discussion in this area has been drawn from experiences in education where the prevalent model is best described as supported on-line learning. Propositions on the structure of the e-learning community, and on the role of the moderator, have been based largely on lessons drawn from practice in higher education. The growing importance of e-learning as a tool for informal learning and team development in business is leading to new types of e-learning communities with different objectives, different boundaries and membership, different demands on the moderator and different measures of effectiveness. Two e-learning communities are outlined and some key characteristics are presented.  相似文献

In 1999-2000 a team of professionals and researchers carried out the largest research study so far undertaken with recipients of housing adaptations in England and Wales to discover how effectively the adaptations had achieved their objectives. Amongst the findings was evidence that well-designed adaptations had beneficial, and/or preventative effects on both physical and mental health; that these benefits were long-term and that they extended beyond the disabled person to help the health of other family members. The evidence presented is linked with key themes from other research to trace in detail the pathways that lead from unadapted or badly adapted housing to mental and physical ill health. It is suggested that these themes, including the meaning of home and the concept of intrusion are vital to understanding how health gains may be achieved through adaptation, and are useful and relevant to the broader debate on links between housing and health.  相似文献
