Discrimination and memory for video films of women performing different activities was investigated in 5.5 month-old infants. In Experiment 1, infants (N = 24) were familiarized to the faces of one of three women performing one of three repetitive activities (blowing bubbles, brushing hair, and brushing teeth). Overall, results indicated discrimination and memory for the actions but not the faces after both a 1-min and a 7-week delay. Memory was demonstrated by a visual preference for the novel actions after the 1-min delay and for the familiar actions after the 7-week delay, replicating prior findings that preferences shift as a function of retention time. Experiment 2 (N = 12) demonstrated discrimination and memory for the faces when infants were presented in static poses at the 1-min delay, but not the 7-week delay. In Experiment 3 (N = 18), discrimination of the actions was replicated, but no discrimination among the objects embedded in the actions (hairbrush, bubble wand, toothbrush) was found. These findings demonstrate the attentional salience of actions over faces in dynamic events to 5.5 month-olds. They highlight the disparity between results generated from moving versus static displays in infancy research and emphasize the importance of using dynamic events as a basis for generalizing about perception and memory for events in the real world.  相似文献

In two Bachelor of Education courses, students experienced social constructivist principles for teaching Elementary Language Arts. In the first course, they were introduced to the theory upon which curricula, methods, and strategies are based. Implications for instruction were explored through discussion of readings and participation in child-centered activities, later examined from the points of view of the learner and of the theory. In the second course, the seminar group pursued advanced questions about social constructivist theories, methods, and strategies. Students kept informal written responses to readings; shared reactions, ideas, and questions; suggested readings and approaches; and summarized their understanding in final papers. Students evaluated both experiences as being exceptionally useful to their own understanding of instruction. Four pedagogical points are worth consideration. First, despite differences in their undergraduate disciplines, all students demonstrated that they could contribute to their peers' construction of knowledge or meaning making of the concepts and theories examined. Second, the sequence of the two courses seemed to be important for establishing a base of understanding and inquiry for the seminar group. Third, students used metacognitive analysis of their experiences in order to examine their own learning, to investigate learning in general, and to inquire into the use of this understanding in their teaching. Fourth, students' excitement, as expressed in their evaluations, suggests that they began to construct a notion of what a teacher can be, of the obligation that a teacher has to continuous professional development, and of the need to inquire about their own practice.  相似文献

Abstract

The aim of this study, carried out in association with beef cattle producers, was to explore the capacity of farms to adapt, from a techno-conomic point of view, to both structural changes in consumer demand for beef products and market disruptions (sudden drop in beef consumption due partly to media coverage of bovine spongiform encephalopathy [BSE] and foot-and-mouth disease in the winter 2000/2001). The aim is to help farmers and advisors to find solutions to fit farmers’ management choices with their strategic objectives. The flexibility concept was adopted in order to examine how farms reacted to the winter 2000/2001 crisis, and was based on several technical, economic and sociological surveys. A series of variables was proposed and several hypotheses were formulated regarding their impact on farm flexibility. Four types of farm strategy were identified using different combinations of the degree of importance of these variables, with technical, economic and marketing flexibilities specific to each type. The results revealed the different combinations of flexibility-types possible (technical, economic, marketing) and explain why cattle farmers reacted as they did. Analysis of farm flexibility also revealed situations where these technical, economic and marketing flexibilities were either complementary or incompatible. For traditional livestock farmers, high flexibility (technical and economic) allowed them to minimize the impact of the crisis on their systems. In other cases, low flexibility either resulted in inertia, or led farmers to react by seeking solutions outside the cattle farming system. Development groups should take into account these parameters when interacting with farmers. We propose a framework to qualify the use of information resources by farmers, relative to their flexibility.  相似文献

The Audit     
The value of the audit process to libraries is examined and questioned. Although generally accepted accounting principles (GAAP) are followed by accountants in all fields, these policies and procedures are not always relevant for serials, particularly electronic journals. Adhering to these best practices does little to achieve professed goals and desired outcomes.  相似文献

The OA Gourmand     
It is trendy to be a supporter of Open Access publication with even journal publishers finding a role in communicating research results through this mechanism. When discussing Open Access it is rare for all parties to be clear about why Open Access is endorsed. The differences between Green Open Access and Gold Open Access can lead to unclear communication when the distinctions between the two are avoided.  相似文献

Stress management for adult women students in community colleges is essential because of the enormous demands they face from family, career, and financial responsibilities. Community colleges and adult educators must help adult women students identify their major sources of stress as well as provide strategies to alleviate those stressors. An extensive review of the literature and a campus-based study found high levels of stress resulting from parenting, nancial, and health concerns. Age was also found to be an important stress factor. Recommendations for helping adult women students are discussed.  相似文献

The aim of this study was to determine whether there is an effect of time of day on the adaptation to strength training at maximal effort. Fourteen participants took part in this experiment. Their peak anaerobic power (Wingate anaerobic test) and peak knee extension torque at six angular velocities (1.05, 2.10, 3.14, 4.19, 5.24 and 6.29 rad · s -1 ) were recorded in the morning (between 07:00 and 08:00 h) and in the evening (between 17:00 and 18:00 h) just before and 2 weeks after a 6 week course of regular training. Seven of them trained only in the morning and seven only in the evening. Multivariate analysis of variance revealed a significant group 2 pre-/post-training 2 time of day interaction effect for peak torque and peak anaerobic power. Before training, in both groups, peak torque and peak anaerobic power were significantly higher in the evening than in the morning. After training, there was no significant difference in peak torque and peak anaerobic power between the morning and the evening for the morning training group. In contrast, in the evening training group, peak torque and peak anaerobic power were higher in the evening than in the morning. As a result of training, both peak torque and peak anaerobic power increased from their initial values as expected. The morning training group improved their peak anaerobic power significantly in the morning and in the evening, the absolute increase being larger in the morning than in the evening. The evening training group did not improve their peak anaerobic power in the morning, whereas it improved significantly in the evening. Although peak torque was significantly improved by training in the morning and evening in both groups, the absolute increase was greater in the morning than in the evening in the morning training group, whereas the opposite was the case for the evening training group. These results suggest that training twice a week at a specific hour increases the peak torque and the peak anaerobic power specifically at this hour and demonstrates that there is a temporal specificity to strength training.  相似文献
