Using data from the Fragile Families and Child Wellbeing Study, we examined patterns of nonresident father involvement 1 and 3 years after a nonmarital birth (N = 893). Cluster analyses were used to determine patterns of involvement across different father behaviors. About half of fathers displayed low involvement when children were 1 and 3 years old, one fourth of fathers maintained high involvement, and equal remaining proportions increased or decreased involvement over time. Multinomial logistic analyses indicated that better relationships between parents were associated with consistently high versus low involvement. Better relationships with each others’ extended family also predicted remaining highly involved and increasing involvement over time. Parents’ romantic relationship status was closely associated with patterns of involvement.  相似文献

In initial teacher education, it is a challenge to foster the development of teaching skills proximal to classroom action. In this study, the impact of a combined practical and theoretical university-based term on preservice teachers’ professional vision is investigated by a video-based approach to supervising their knowledge acquisition and assessing their learning outcomes. Participants were N = 109 preservice teachers attending a 5-month theory practice term guided through video-based courses about effective teaching and learning. We measured their changes in professional vision using the video-based tool Observer. Our results show that preservice teachers positively change their professional vision during the theory practice term, especially if they show low entry levels at the beginning. Their notes on the observed teaching lessons illustrate these changes.  相似文献

The initial section of this article describes the frequency with which people are exposed to various forms of traumatic stressors and the limitations of linear thinking in both assessing and treating the consequences of traumatic exposure as reported by the Institute of Medicine. The middle section of the article identifies the research and theory that supports the utility of systemic thinking and action in working with traumatised systems, especially families. The final section includes an outline of a protocol for family therapists and other systems‐informed practices to help traumatised families and other systems. A critical part of the protocol is that it meets the standards of trauma‐informed practice reflected by the Green Cross Academy of Traumatology and the International Society of Traumatic Stress Studies (ISTSS) guidelines, and the six criteria for evaluating treatment approaches. These criteria include do no harm, exposure titration control, reciprocal inhibition tuning, quantity and quantity of training, fit and fidelity and evidence of effectiveness.  相似文献

A Department of Health initiative has supported the implementation of Looking After Children in over 90 per cent of local authorities in England. The process has required major organisational change and new values and attitudes towards children looked after away from home. Difficulties arise where management and monitoring systems are not available to support these wider changes and to assess the quality of practice. Nevertheless clear benefits to using the system can be identified. Pilot projects in Sweden, Canada and Australia provide an opportunity to compare experiences internationally; strong parallels are evident in some of the current issues facing child welfare.  相似文献

An environmental assessment of amine oxides has been conducted under the OECD SIDS High Production Volume (HPV) Program via the Global International Council of Chemical Associations (ICCA) Amine Oxides Consortium. Amine oxides are primarily used in conjunction with surfactants in cleaning and personal care products. Given the lack of persistence or bioaccumulation, and the low likelihood of these chemicals partitioning to soil, the focus of the environmental assessment is on the aquatic environment. In the United States, the E-FAST model is used to estimate effluent concentrations in the United States from manufacturing facilities and from municipal facilities resulting from consumer product uses. Reasonable worst-case ratios of predicted environmental concentration (PEC) to predicted no effect concentration (PNEC) range from 0.04 to 0.003, demonstrating that these chemicals are a low risk to the environment.  相似文献

Inter-firm collaboration among knowledge-intensive firms is increasing as a result of accelerating competition, falling regulatory barriers and rising customer expectations. Resource dependency theory is used to position knowledge as the key resource for the knowledge-based enterprise and to examine the suitability of alliances as a mode of knowledge acquisition and exchange, contrasted particularly with merger and acquisition. The alliance and knowledge literatures are reviewed, and particular attention is paid to the critical alliance formation stage. This stage is reviewed against a research model that posits firm performance in knowledge creation arises from a number of factors, including the motivation for an alliance, partner firm characteristics (the ability to develop and sustain valuable resources; absorptive capacity; combinative capability; experience with alliances; and appropriate design for knowledge exchange), the development of operating structures and norms, and the choice of alliance structure. The paper concludes with suggestions for future research..  相似文献
