This prospective, longitudinal study showed that an intense educational program significantly improved academic performance in underserved students who were selected solely for their desire to participate in the program and their parents' willingness to support them. Mean performance in six representative components of the Woodcock-Johnson Tests of Achievement–Revised improved at a rate that substantially exceeded one year for each year in the program. During three years of attendance, performance levels increased from below to more than two years above grade level. 相似文献

This article examines the extent to which citizens of migrant origin are included within discourses of national identity in civic education curricula in England, France and Ireland. We explore how much space is given to citizens of migrant origin in discourses of national identity in civic education curricula and how they fit with central values normalized by a higher degree of recognition in schools. Although early immigration systems assumed that incorporation of migrants into the national polity would take place via socialization in education, the failure to include citizens of migrant origin in the contemporary ‘imagined community’ articulated in civic education discourses risks marginalizing some citizens which gives rise to a sovereignty gap. The disparity between legal and cultural belonging of some individuals in Western Europe presents a major challenge for education systems which are tasked with making national identity discourse resonate with a globalized citizenry. The study found that despite commonalities around the promotion of human rights and democracy, civic education curricula diverge with regard to representation of religion. Moreover, nationalistic aspects of the French model contrast with a multicultural, and recently global, approach to citizenship education in England and the promotion of European citizenship in Ireland. 相似文献

Aging education is relatively new to the university, and our understanding of the perspectives students bring to aging populations is correspondingly limited. This investigation surveys 546 students at a midsized, Midwestern university to explore students' views toward elders, toward serving elders, and toward the relevance of aging education for various other areas of study. Our results suggest generally favorable attitudes: older students and students with greater contact with aging populations were more positive than their counterparts; gender, GPA, and aging courses taken showed sporadic or no effects on various attitudes. These preliminary findings offer a baseline for future investigations. Our findings suggest that students who have more contact through friendship and volunteer experiences have more positive attitudes toward working with older adults. Additional research is needed to examine if type of gerontological instruction is associated with attitudes toward aging and aging education. 相似文献

Toward a holistic approach to communication: The effect of “pure” hemispheric reception on message acceptance 总被引:1,自引:1,他引:0
This study examined the relationship between hemispheric processing of complex messages and message acceptance. In particular the research sought to answer several questions regarding the processing and interpretation of persuasive messages and message sources. Based on the results of this research it was concluded that (1) the brain's right and left hemispheres, when isolated from one another, process information according to a particular “style,” (2) that semantic properties of language influence hemispheric processing, and (3) that message sources are perceived differently by the right and left hemispheres. Potential implications for the study of communication in terms of message style and acceptability, language intensity, perceptions of source, and perceptions of threat conclude this analysis. 相似文献

Dielectrophoresis (DEP), the phenomenon of directed motion of electrically polarizable particles in a nonuniform electric field, is promising for applications in biochemical separation and filtration. For colloidal particles in suspension, the relaxation of the ionic species in the shear layer gives rise to a frequency-dependent, bidirectional DEP force in the radio frequency range. However, quantification methods of the DEP force on individual particles with the pico-Newton resolution required for the development of theories and design of device applications are lacking. We report the use of optical tweezers as a force sensor and a lock-in phase-sensitive technique for analysis of the particle motion in an amplitude modulated DEP force. The coherent detection and sensing scheme yielded not only unprecedented sensitivity for DEP force measurements, but also provided a selectivity that clearly distinguishes the pure DEP force from all the other forces in the system, including electrophoresis, electro-osmosis, heat-induced convection, and Brownian forces, all of which can hamper accurate measurements through other existing methods. Using optical tweezers-based force transducers already developed in our laboratory, we have results that quantify the frequency-dependent DEP force and the crossover frequency of individual particles with this new experimental method. 相似文献

The ability to ensure the desired performance of the cooperative-antagonistic multi-agent networks (MANs) in the presence of communication constraints is an important task in many applications of real systems. In this paper, under the proposed event-triggered condition (ETC), different types of consensus are obtained under different network topology. We concentrates on the event-based bipartite consensus. It is shown that under the proposed ETC (i) the addressed cooperative-antagonistic network with arbitrary communication delays reaches bipartite consensus provided that the network is balanced; (ii) the network model reaches zero if the network is unbalanced. Further, to avoid the continuously verifying the triggering condition, a self-triggered algorithm is proposed for realizing the bipartite consensus of the network model. A numerical example is given to illustrate the effectiveness of the theoretical results. 相似文献
