With permission from Childbirth Connection, the “Executive Summary” for the Listening to Mothers II survey is reprinted, here. The landmark Listening to Mothers I report, published in 2002, described the first national U.S. survey of women''s maternity experiences. It offered an unprecedented opportunity to understand attitudes, feelings, knowledge, use of obstetric practices, outcomes, and other dimensions of the maternity experience. Listening to Mothers II, a national survey of U.S. women who gave birth in 2005 that was published in 2006, continues to break new ground. Although continuing to document many core items measured in the first survey, the second survey includes much new content, exploring earlier topics in greater depth, as well as some new and timely topics.  相似文献

The present study describes a peer-tutoring program designed to utilize computerassisted instruction to help first through fourth graders who were entering a new school. Tutored girls increased their positive self-perceptions as a result of the tutoring program, whereas boys declined in positive self-perceptions, while exhibiting gains in reading scores. These findings suggest that prevention efforts need to consider the specific adaptation needs of transfer students by gender so as to insure a maximum fit between individual need and program scope.  相似文献

Optimal cognitive distance and absorptive capacity   总被引:3,自引:0,他引:3  
In this paper we test the relation between cognitive distance and innovation performance of firms engaged in technology-based alliances. The key finding is that the hypothesis of an inverted U-shaped effect of cognitive distance on innovation performance of firms is confirmed. Moreover, as expected, we found that the positive effect for firms is much higher when engaging in more radical, exploratory alliances than in more exploitative alliances. The effect of cumulative R&D turns out to be mixed. It appears to increase absorptive capacity, as expected, but there is clear evidence that it also reduces the effect of cognitive distance on novelty value, making it increasingly difficult to find additional novelty.  相似文献

This paper explores the notion of impact in the context of academic development programs and considers how it can be described and understood. We argue that impact has a range of meanings and academic development programs such as graduate certificates have a broad group of stakeholders and hence the impact is different for each group depending on how the program aims and objectives are defined and understood. In finding a way through the difficulties of evaluating impact in academic development we point to the importance of clearly conceptualizing the notion of impact, a careful identification of the assumptions underpinning any program and an understanding of who academic development will benefit and how. We suggest that impact in academic development cannot be understood without taking account of the range of possible impacts and the difficulty of attributing simple cause and effect to a complex environment.  相似文献

This article investigates when and how teams engage in team learning behaviours (TLB). More specifically, it looks into how different leadership styles facilitate TLB by influencing the social conditions that proceed them. 498 healthcare workers from 28 nursery teams filled out a questionnaire measuring the concepts leadership style, TLB, social cohesion and team psychological safety. Analysis was performed using structural equation modelling. The results of this cross-sectional study show that transformational leadership predicts TLB better then laissez-faire leadership, because transformational leadership is primarily related to team psychological safety and only secondarily to social cohesion while for laissez-faire leadership it works the other way around. Transformational leadership matters because it facilitates psychological safety in the team.  相似文献

This causal-comparative study researched the effects of dual enrollment and Huskins Bill course experience on traditional-age North Carolina community college students. The study examined course effects on academic success and graduation rate using quantitative statistical measures including parametric and nonparametric means comparisons. The study found that dual enrollment and Huskins Bill courses showed a positive effect on grade point average (GPA) and graduation rate, and this effect is evident in technical, medical, and college transfer programs. The study also showed a positive correlation between number of courses and student GPA and graduation rate. Findings in this study support continuing and expanding dual enrollment offerings as one aid for college readiness.  相似文献

The effect on drag of a Speedo Fast-skin suit compared to a conventional suit was studied in 13 subjects (6 males, 7 females) swimming at different velocities between 1.0 and 2.0 m.s-1. The active drag force was directly measured during front crawl swimming using a system of underwater push-off pads instrumented with a force transducer (MAD system). For a range of swimming speeds (1.1, 1.3, 1.5 and 1.7 m.s-1), drag values were estimated. On a group level, a statistically non-significant drag reduction effect of 2% was observed for the Fast-skin suit (p = 0.31). Therefore, the 7.5% reduction in drag claimed by the swimwear manufacturer was not corroborated.  相似文献

This empirical study investigates students' learning choices for mathematics and statistics in a blended learning environment, composed of both online and face-to-face learning components. The students (N = 730) were university freshmen with a strong diversity in prior schooling and a wide range of proficiency in quantitative subjects. In this context, we investigated the impact that individual differences in achievement emotions (enjoyment, anxiety, boredom, hopelessness) had on students' learning choices, in terms of the intensity of using the online learning mode versus the face-to-face mode. Unlike the general level of learning activities, which is only minimally influenced by achievement emotions, these emotions appear to have a moderately strong effect on a student's preference for online learning. Following this, we explored the antecedents of achievement emotions. Through the use of path-modeling, we conclude that while goal setting behavior only marginally impacts achievement emotions, effort views—a crucial component of the social-cognitive model of implicit theories of intelligence—have a substantial impact on achievement emotions.  相似文献

The Educational Forces Inventory (EFI) is a technique for assessing the constellation of forces in the teacher’s social-psychological field. Thereby, important stress points for teachers are identified and their work in the classroom is facilitated. The EFI charts the relative influence of each of 13 forces that are important factors in the educational settting. Teachers are asked to characterize each force along two dimensions: the amount of influence it exerts upon the classroom process, and the degree to which this influence is positive or negative. Several hundred teachers and teaching assistants in Follow Through classrooms throughout the country participated in a field test of the instrument, with concurrent administration of the Purdue Teacher Opinionaire (PTO), an established measure of teacher morale. The high rate of return and correct completion on the EFI indicated that it is a practical technique. In addition, the data indicated validity for the instrument in three important respects: (1) the pattern-of-importance ratings correspond to independently assessed patterns of physical and social distance; (2) the positive/negative ratings for particular forces correlated substantially with corresponding subscores of the PTO; and (3) the pattern of responses reflected aspects of internal consistency. Some ways of utilizing EFI data are discussed: how to plot and interpret two-dimensional force fields, and how to use them in program implementation, especially to facilitate the work of the teacher in the classroom.  相似文献

Peer feedback is frequently implemented with academic writing tasks in higher education. However, a quantitative synthesis is still lacking for the impact that peer feedback has on students’ writing performance. The current study conveyed two types of observations. First, regarding the impact of peer feedback on writing performance, this study synthesized the results of 24 quantitative studies reporting on higher education students’ academic writing performance after peer feedback. Engagement in peer feedback resulted in larger writing improvements compared to (no-feedback) controls (g?=?0.91 [0.41, 1.42]) and compared to self-assessment (g?=?0.33 [0.01, 0.64]). Peer feedback and teacher feedback resulted in similar writing improvements (g?=?0.46 [-0.44, 1.36]). The nature of the peer feedback significantly moderated the impact that peer feedback had on students’ writing improvement, whereas only a theoretically plausible, though non-significant moderating pattern was found for the number of peers that students engaged with. Second, this study shows that the number of well-controlled studies into the effects of peer feedback on writing is still low, indicating the need for more quantitative, methodologically sound research in this field. Findings and implications are discussed both for higher education teaching practice and future research approaches and directions.  相似文献
