The authors tested a series of models linking spanking and child social‐emotional outcomes using a sample of 3,870 families from the Fragile Families and Child Wellbeing study. Spanking was measured by the number of times the focal child was spanked by the mother at ages 1, 3, and 5. Internalizing and externalizing symptoms were assessed using the Child Behavior Checklist at ages 3 and 5. Child emotionality was used to index child behavior at age 1. A series of nested transactional and cascade models was tested through structural equation modeling. The final model supported transactional effects between spanking and child externalizing behaviors over child ages 1, 3, and 5. In addition, one cascade effect was found: Spanking at age 1 was related to greater externalizing behavior at age 3, which was related to greater internalizing behavior at age 5. Implications for family theory and future research are discussed.  相似文献

While numerous studies focus on the prevalence and change of different living arrangements, this study focuses on the social selectivity of living together with a partner compared to living without a partner. In the context of marriage, there is extensive empirical evidence that the tendency to enter or dissolve a union is dependent on specific conditions. However, little is known about the resulting social structures and how these change. The present study investigates this on the basis of cumulated German Microcensuses. A logistic regression model is suggested in which the age dependency of living in a partnership is considered and the change of social selectivity is examined on the basis of interaction effects with the cohort. It is shown that men with low education and low employment and income prospects have always had low odds of living in a partnership. In more recent cohorts such a pattern evolves for women as well. Changes in household production and in preferences and opportunities of mate selection are discussed as explanations.  相似文献

This feasibility study was prepared by Statistics Canada, under arrangement with the Strategic Policy Research Directorate, Human Resources and Skills Development Canada (HRSDC). It investigates issues associated with conducting surveys of abuse and neglect of older adults in community and institutional settings in Canada. A roadmap is provided for the work ahead, including options for a sampling frame, collection approaches, estimated costs, and an activity schedule.  相似文献

Problems with self-control are seen as a key cause of problem gambling behavior. Yet, self-control is rarely studied directly in gambling studies. We demonstrated that self-report and behavioral measures (derived from the strength model of self-control) show lower trait self-control in problem gamblers. In Study 1, a sample of 2,208 undergraduate students from the University of Guelph, Canada (73% female, mean age?=?19?years, SD?=?4) completed a self-report measure of self-control strength. In Study 2, a sample of 296 University of Guelph students and staff (58% female, mean age?=?19?years, SD?=?2) completed multiple behavioral measures of self-control strength. Both studies demonstrated that, compared to lower-risk gamblers, higher-risk gamblers have relative trait self-control deficits.  相似文献

The double journey (work and study) may result or aggravate health problems, including sleep disturbances, as observed in previous studies with high school students. The aim of this study is to analyze the sleep-wake cycle and perceived sleepiness of working college students during weekdays. Twenty-three healthy college male students, 21-24 years old, working during the day and attending classes in the evening, participated in this study. During five consecutive days, the students filled out daily activities logs and wore actigraphs. Mean sleeping time was lower than 6 hours per night. No significant differences were observed in the sleep-wake cycle during the weekdays. The observed lack of changes in the sleepwake cycle of these college students might occur as participants were not on a free schedule, but exposed to social constraints, as was the regular attendance to evening college and day work activities. Sleepiness worsened over the evening school hours. Those results show the burden carried by College students who perform double activities - work and study.  相似文献

In industrialized countries musculoskeletal disorders (MSD) play an import role and are often responsible for almost one third of the total sick leave. The changes in the demographic profiles, i.e. aging work forces might even worsen this situation in the future. For a highly productive and sustainable use of human resources in production systems, ergonomics offers high potentials. In the recent years the authors have developed several ergonomic risk assessment tools, especially for the use in automotive industries. These methods may be used during the planning phases in the Tech Centers as well as during the production phase at shop floor level. The tools might also be used for a standardized communication in between the Tech Center and the plants to improve the effects of "lessons learned" for the design and layout of workstations and processes and the optimization of vehicle components. This paper describes suitable risk assessment tools as well as the integration of these tools into the vehicle development process. It introduces a comprehensive management approach for the integration of ergonomics into the management of production systems.  相似文献

Coordinating care for hospitalized patients requires the use of multiple sources of information. Using a macroergonomic framework (i.e. the work system model), we conducted interviews and observations of care managers involved in care coordination across transitions of care. When information is distributed across multiple health IT applications, care managers experience a range of challenges, including organizational barriers, technology design problems, skills and knowledge issues, and task performance demands (i.e. issues related to individual information processing and management and sharing of information). These challenges can be used as a checklist to evaluate the proposed IT infrastructure that will allow the integration of multiple health IT applications and, therefore, support coordination across transitions of care.  相似文献

The relative contribution of substrate depth and vegetation type on temperature mitigation and stormwater runoff reduction was studied in an experimental green roof in North eastern Italy. Two substrate depths (120 and 200?mm) and two vegetation types (herbaceous plants and shrubs, respectively) were used, and compared to control modules with similar substrate depths but left bare of vegetation. Experimental observations showed that: a) green roofs substantially reduce thermal load over the rooftop, with significant effects of substrate depth and no apparent impact of vegetation type; b) thermal effects are strongly influenced by substrate water content; c) green roofs strongly reduce water runoff with significant substrate x vegetation effects. Our data suggest that green roof design addressed to optimization of the thermal functions should take into account adequate planning of substrate depth. Moreover, our data show that vegetated modules out-competed medium-only ones in terms of runoff reduction capacity, in accordance with some previous studies. Both shrub-vegetated and herbaceous modules intercepted and stored more than 90% rainfall during intense precipitation events, with no significant difference between the two vegetation types despite different substrate depths.  相似文献

The current studies examined the importance of domain content in the processes of identity development using two approaches—narrative and status. We examined personal narratives for identity domain content, the co‐occurrence of different contents, and the relations between content and processes, using two approaches to identity—status and narrative. Across two studies, 762 participants (average age = 19 years) and 2214 narratives, traditional ideological and interpersonal status domains were present, but so was a novel domain: existential concerns. Narrative identity processes were more frequent in narratives with multiple contents, and relations between identity statuses processes and narrative processes were modest. We discuss theoretical implications, the importance of examining content, and the utility of narrative approaches for doing so.  相似文献
