AbstractStrenuous physical activity has been linked to pelvic floor disorders in women. Using a novel wireless intra-vaginal pressure transducer, intra-abdominal pressure was measured during diverse activities in a laboratory. Fifty-seven women performed a prescribed protocol using the intra-vaginal pressure transducer. We calculated maximal, area under the curve and first moment of the area intra-abdominal pressure for each activity. Planned comparisons of pressure were made between levels of walking and cycling and between activities with reported high pressure in the literature. Findings indicate variability in intra-abdominal pressure amongst individuals doing the same activity, especially in activities that required regulation of effort. There were statistically significant differences in maximal pressure between levels of walking, cycling and high pressure activities. Results for area under the curve and first moment of the area were not always consistent with maximal pressure. Coughing had the highest maximal pressure, but had lower area under the curve and first moment of the area compared to most activities. Our data reflect novel findings of maximal, area under the curve and first moment of the area measures of intra-abdominal pressure, which may have clinical relevance for how physical activity relates to pelvic floor dysfunction. 相似文献

We investigated the effects of different exercise intensities on C-reactive protein (CRP), and whether changes in CRP levels correlated with blood lipid levels. Ten men exercised at 25%, 65%, and 85% of their maximum oxygen consumption rates. Participants' blood was analyzed for CRP and blood lipid levels before and after the exercise sessions. Although there was an intensity effect for postexercise high-density lipoprotein levels, there were no significant differences or correlations for postexercise CRP levels or between CRP and lipid levels across the three exercise intensities. In an acute aerobic bout model with isoenergetic expenditures, CRP was not affected by the exercise intensity. Additionally, changes in blood lipid levels might not have been connected to CRP levels for physically fit participants. 相似文献

This research identifies six online course evaluation instruments used nationally or in statewide systems. We examined the characteristics (i.e., number of standards and criteria) and coded the criteria that guide the design of online courses. We discussed the focus of the instruments and their unique features. 相似文献

The University of Florida Health Science Center Library (UF-HSCL) surveyed MEDLINE end-user activities of the faculty from the six colleges which the UF-HSCL serves. A questionnaire was developed and sent to all faculty members. The Basic SAS program was used to analyze the collected data. This survey was intended to identify the users, the reasons for faculty members not being end users, the purpose for searching MEDLINE, the information retrieval methods, the level of end-user satisfaction, and the librarian's role in information retrieval activities. Many findings from this survey were in agreement with those of the 1988 study by the National Library of Medicine. 相似文献

Word-of-mouth (WOM) is informal communication between consumers about products and services. By using text mining techniques, WOM measured for volume and valence at the movie box office in Taiwan. A simultaneous regression of a panel Granger causality test for WOM and corresponding film performance was performed. The empirical results show that dynamic causality only runs from box office to WOM volume in the short run analysis, and the causality between WOM volume and box office is bidirectional in the long run analysis. Potential customers attend movies because of WOM in the short run, but in the long run, box office forms a signal and creates WOM. In WOM valence analysis, causality runs from positive critics to the box office in the short run, and it runs from negative critics to box office in the long run. WOM providers may need to develop different strategies for encouraging WOM behavior among their users. The implication for film managers and marketers is that a reliable way to affect box office is to stimulate positive critics in the short run and negative critics in the long run. 相似文献

Science internships where students work with scientists have been suggested to have many positive impacts on students’ science learning. However, little research has been conducted to investigate the types of interactions that are beneficial for the development of science knowledge through an authentic internship experience. The purpose of this study was to illustrate the key features of dynamic interactions and activities involved in an open-inquiry-based internship programme for high school students. Drawing on cultural-historical activity theory, we aimed to describe the features of the internship activity system in terms of the moments of subject, object, tools, community, rules, division of labour, and outcome. Our analysis suggests that the activity system of the university internship has unique features that promote optimal science learning opportunities. The implications of these unique features are discussed and suggestions are made to improve K–12 science education. 相似文献

The objective of this paper is to examine the effectiveness of a creativity-fostering program in industrial engineering and management (IE&M) curriculum reform. Fostering creativity in students has become a crucial issue in industrial engineering education. In a survey of previous studies, we found few on IE&M curriculum reform. In particular, no study has dealt directly with fostering students’ creativity. In this study, we propose an IE&M curriculum reform program. The core of this program is intended to enhance students’ creative problem solving ability. Based on this concept, three required courses were developed: industrial communication, creative problem solving, and scientific research methodology. To investigate the effectiveness of this curriculum reform program, we conducted a two-year follow-up study. One hundred seventy-seven IE&M undergraduates from Yuan-Ze University participated this study, and Torrance Tests of Creative Thinking (TTCT) were used to measure changes in their creativity. The results showed that the students, after completing this reformed curriculum program, had significantly improved their creativity. 相似文献

Maternal Support Networks, Maternal Cognitions, and Young Children's Social and Cognitive Development 总被引:1,自引:0,他引:1
The relations among maternal support networks, maternal perceptions of parenting, maternal attributions for parenting situations, and children's social development, as indexed by peer acceptance, and cognitive performance, as indexed by the PPVT-R and PSI, were examined in a sample of 69 mothers and their preschool-age children. Network characteristics directly predicted cognitive performance and indirectly predicted peer acceptance through effects on maternal perceptions and attributions. Parent cognitions as mediators of network effects on children's development are discussed, addressing variation due to network dimensions, types of parent cognitions, and domain of children's development. 相似文献
