AIMS AND OBJECTIVES: Access to health information is important for the well-being of people living in the community after spinal cord injury (SCI). In order to design appropriate information interventions, it is critical first to understand the information sources typically used. The goal of this study therefore is to identify the information-seeking practices of this group. SAMPLE AND METHODS: A sample of 207 individuals living in the community following traumatic spinal cord injury were surveyed regarding their ongoing information needs and practices for seeking information. RESULTS: The results reveal that respondents have unmet information needs, despite the fact that they typically access information through a variety of channels. SCI specialists are the most commonly used source, although they are viewed as relatively inaccessible. By contrast, the Internet (used by a relatively high proportion of respondents) is viewed as comparatively accessible, although there are some concerns about the quality of information found there. CONCLUSIONS: These survey results point to the need for an information source that is accessible and delivers high quality information. Although respondents use a variety of information sources, none meets this ideal profile. Information professionals should consider this gap in the design of information interventions. 相似文献

The current study tests the mastery hypothesis as an explanation for the affective benefits of acute exercise. Participants were 204 undergraduate women who were participating in self-selected aerobic dance classes. Following the class, participants were asked to rate their exercise performance on a 5-point, Likert-type scale. Affect questionnaires were completed prior to and at 5 and 20 min following the aerobic dance class. Results indicated an overall improvement in affect following exercise. Negative valenced subscales were unaffected by performance ratings. Both groups showed similar reductions in these states. There was, however, a significant Group x Time interaction for the positive valenced subscales. High-performance participants reported greater increase in these variables throughout recovery than did low-performance participants. These data support the mastery hypothesis as an explanation for the exercise-induced change in positive affective states. 相似文献

The relations of observed parental warmth and positive expressivity and children's effortful control and ego control with children's high versus low emotional expressivity were examined in a 2-wave study of 180 children (M age = 112.8 months). There were quadratic relations between adults' reports of children's emotional expressivity and effortful control; moderate expressivity was associated with high effortful control. Structural equation models supported the hypothesis that children's ego overcontrol (versus undercontrol) mediated the relation between parental warmth or positive expressivity and children's emotional expressivity, although parenting at the follow-up did not uniquely predict in children's expressivity after controlling for the relations in these constructs over time. The alternative hypothesis that children's ego overcontrol elicited positive parenting and expressivity also was supported. 相似文献

This paper reflects our commitments as teacher educators to develop the skills, knowledge and interests amongst ‘nearly qualified teachers’ to establish action learning as an integral part of their professional practice. We outline the development of an undergraduate unit that is endeavouring to achieve this at Edith Cowan University, Western Australia. Key principles and characteristics of action research and action learning are used as a framework for critical reflection on the unit. Attempting to provide learning experiences that adhere to these principles within the context of initial teacher education courses is identified as a challenging process. Planned developments in which we seek to enhance the extent to which teacher education can be seen to embrace and promote action research and action learning are discussed. 相似文献

The relations of regulation and emotionality to elementary school children's social functioning were examined. Teachers and peer reproted on children's social functioning; I parent and teacher rated children on various measures of regulation, resiliency, and emotionality; and a behavioural index of regulation was obtained. The effects of individual differences in attentional regulation on social status and socially appropriate behavior were mediated by resiliency, and dispositional negative emotionality moderated the positive relation between attentional control and resiliency (with this path being stronger for children high in negative emotinality). The effects of behavioural regulation were not mediated by resiliency; however, the relation of behavioral regulation to socilaly appropriate behaviour (but not social status) was moderated by negative emotionality, with effects being significant and higher for children high in negative emotionality. 相似文献

Electro-osmotic flow (EOF) pumps are attractive for fluid manipulation in microfluidic channels. Open channel EOF pumps can produce high pressures and flow rates, and are relatively easy to fabricate on-chip or integrate with other microfluidic or electrical components. An EOF pump design that is conducive to on-chip fabrication consists of multiple small channel arms feeding into a larger flow channel. We have fabricated this type of pump design using a thin film deposition process that avoids wafer bonding. We have evaluated pumps fabricated on both silicon and glass substrates. Consistent flow rate versus electric field were obtained. For the range of 40–400 V, flow rates of 0.19–2.30 μL∕min were measured. Theoretical calculations of pump efficiency were made, as well as calculations of the mechanical power generated by various pump shapes, to investigate design parameters that should improve future pumps. 相似文献
