Zadie Smith's most recent novel, On Beauty (2005 Smith, Z. 2005. On Beauty, London and New York: Penguin.  [Google Scholar]), declares its connection to E. M. Forster's Howards End (1910 Forster, E. M. 1910. Howards End, London: Edward Arnold.  [Google Scholar]) with its first line, while the novel's title comes from Elaine Scarry's On Beauty and Being Just (1999 Scarry, E. 1999. On Beauty and Being Just, Princeton, NJ: Princeton University Press.  [Google Scholar]). At least as important for understanding Smith's central vision are the novel's allusions to Zora Neale Hurston's Their Eyes Were Watching God (1937 Hurston, Z. N. 1987. Their Eyes Were Watching God, London: Virago Modern Classics.  [Google Scholar]) and Tell My Horse: Voodoo and Life in Haiti and Jamaica (1938 Hurston, Z. N. 1990. Tell My Horse: Voodoo and Life in Haiti and Jamaica, New York: Perennial Library.  [Google Scholar]).  相似文献

One likely mechanism in learning new skills is change in synchronous connections between distributed neural networks, which can be measured by coherence analysis of electroencephalographic patterns. This study examined coherence changes during the learning of two tasks, a word association task and a figure association task. Although learning curves were similar for both tasks, distinct patterns of coherence change were observed. Coherence tended to increase as learning progressed in the figure association task. In contrast, coherence tended to decrease in the word association task, especially within hemisphere. Word learning was coupled with negative intrahemispheric and positive interhemispheric performance–coherence relations in the gamma frequency. Unique to the figure learning task was an increase in the number of positive coherence–performance relations in both delta and theta frequencies across blocks. Results are discussed in light of ongoing efforts to identify the mechanisms that coordinate distributed brain activities during the process of learning. Further research is needed to define patterns of coherence change for different tasks, goals, and brain regions.  相似文献

Given the mixed evidence for the impact of various publicly funded initiatives that aim to foster entrepreneurial activity, this paper empirically examines the efficacy of publicly funded business advisory services in relation to entrepreneurial outcomes. Based on a sample of 228 early-stage firms, of which 101 used business advisory services focused on helping companies secure 1st rounds of financing and start generating revenues, we examine the firm-level impact such services can have on sales growth, innovation, finance and alliances. We find services are positively associated with firms’ sales growth, patents, finance and alliances. We assess statistical and economic significance, and assess robustness to controls for the non-randomness of the firm's using business advisory service program, as well as endogeneity of advisors’ hours spent with firms. Other robustness checks are also included. We find significant robustness of hours spent on sales and finance, but sensitivity of the effect of hours on patents and alliances after controlling for endogeneity.  相似文献

Purpose: The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students’ fitness knowledge and fitness achievement. Method: One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called “CrossFit Challenge” during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results: Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). Conclusions: The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA.  相似文献

Electronic performance support is an expanding area within the field of performance technology. This article reviews and classifies the literature, both conceptual and case-based, in order to assess settings for use, initiating factors for development, and general features of the various systems. Identification of each article reviewed is presented in a matrix of categories that can be used to point those interested in specific aspects of this complex topic to the most pertinent information for their own needs. A general summary of findings follows.  相似文献
