This article intends to illuminate the educational significance of the rhetorical and humanistic tradition. This tradition exerted a great influence upon Western education in the past, but its significance has been largely overlooked by the current philosophy of education. This is probably owing to the centuries-old prejudice against rhetoric and “pedantry” espoused since Plato. Against such criticism, this article intends to defend the educational value of the rhetorical and humanistic tradition by retrieving three essential features as noted by its major theorists—Protagoras (ca. 490–420 B.C.), Cicero (106–43 B.C.), and Leonardo Bruni (1370–1444). These features include public spiritedness, a broader understanding of language, and multi-perspective knowledge. Protagoras, Cicero, and Bruni (each in their own historical context) criticized the closed attitude of philosophers toward monopolizing truth and stood in favor of the public sphere where important matters could be openly discussed. Second, they criticized the philosophical understanding of language as a mirror that represents truth and presented a wider understanding of language that considers the speaker–listener relationship. Third, they developed their concept of multi-perspective knowledge, which was opposed to the philosophical knowledge directed toward a special object, as seen in the Platonic Ideas. The re-evaluation of these three features is absolutely necessary if we wish to rescue the rhetorical and humanistic tradition from the blame of parochial chauvinism. By retrieving these features, the rhetorical and humanistic tradition can help to make contemporary education more publicly open (less closed to specialists), more sensitive to the power of language, and more appropriate within the multi-cultural and multi-lingual experience of the modern world.  相似文献

The present, study was conducted to determine the level of malondialdehyde (MDA) as an index of free radial induced lipid peroxidation and antioxidant vitamins-vitamins A, vitamin C and vitamin E in 75 confirmed cases of urolithiasis. Significantly high level of MDA (p<0.001) with significantly low levels of vitamin E (p<0.001) and vitamin A (p<0.001) with no significant decrease in vitamin C (p>0.05) were observed in the plasma of urolithiasis cases as compared to normal controls. In conclusion, it appears that a role of lipid peroxidation and oxidative function exists in the pathogenesis of urolithiasis. But, the exact mechanism how this occurs remains to be elucidated.  相似文献

This paper describes the fabrication of a waveguide and the analysis of its polarization characteristics by applying light-emitting diode (LED) pumping lights to its surface. By using double tubed coaxial line (DTCL) microwave plasma chemical vapor deposition (MPCVD) equipment, an a-Si:H/SiN multilayer waveguide was fabricated whose thickness could be controlled at nanometer order. The main structural material of the waveguide sample consisted of a combination of layers of amorphous silicon hydrogen and silicon nitrate. Once the sample was ready, another major objective of the experiment was to analyze the polarization characteristics of the fabricated waveguide. The idea of the experiment was to analyze how the waveguide reacts when three types of LED (blue, yellow, and red) are radiated onto its surface. The results showed that the fabrication of the a-Si:H/SiN sample is successful. Most effective transmission results, which accord with the polarization characteristics analysis, were obtained.  相似文献

The use of diagrams in learning and communication is generally considered efficacious and an important skill to cultivate, especially among science students. At the same time, previous research has revealed many problems in student diagram use, including a lack of spontaneity in such use, but the extent to which these problems persist into the tertiary level had not been investigated. The present study examined science and engineering university students’ use of diagrams in note taking to learn information from a written passage, and in a subsequent task of constructing an explanation of that information for another person. The results showed that the students used significantly fewer diagrams in explaining compared to when they were note taking, suggesting that many students may lack awareness of the usefulness of diagrams in effectively communicating information to others. The results also revealed that the students used significantly more diagrams in taking notes from and explaining a passage with higher imageability (i.e. easier to visually imagine) compared to one with lower imageability. Educational implications of the findings are discussed.  相似文献

This study compared U.S. and Japanese grade school teachers’ perceptions of the strengths and weaknesses of children in their classrooms identified as fitting commonly used criteria for a learning disability. U.S. teachers identified 4.0 percent of their children as meeting the criteria and Japanese teachers identified 1.5 percent. The teachers then rated these children’s abilities in the areas of listening, speaking, reading/writing, reasoning, mathematics, social, and study skills. Overall, U.S. and Japanese teachers’ rating patterns were similar on 70 percent of the skills. In most areas where significant differences were found—listening, speaking, reading/writing and study skills—U.S. teachers rated higher percentages of their children as “weaker” than Japanese teachers. A noteworthy exception was the area of social skills where Japanese children received higher percentages of “weak” ratings. U.S. and Japanese teachers also differed in their perceptions of causative factors leading to their children’s learning difficulties. We discuss the findings in terms of U.S.-Japanese differences in writing systems and cultural expectations.  相似文献

This paper explores the determinants of R&D cooperation in Japanese start-ups. Using a sample from an original survey conducted in 2008, we examine the effects of founder-, firm-, and industry-specific characteristics on R&D cooperation by type of partners. Our findings indicate that founder-specific characteristics such as educational background, prior innovation output, and affiliation to academic associations are fairly important in determining R&D cooperation with academic institutes (universities and public research institutes). We also provide evidence that founders’ prior innovation output and work experience have positive and significant effects on R&D cooperation with business partners. With respect to firm-specific characteristics, it is found that firms investing more in R&D tend to engage in R&D cooperation, regardless of the type of partners. Furthermore, it is found that independent firms are less likely to cooperate in R&D with academic institutes than subsidiaries and affiliated firms.  相似文献

Economic Deprivation and Early Childhood Development   总被引:53,自引:0,他引:53  
We consider 3 questions regarding the effects of economic deprivation on child development. First, how are developmental outcomes in childhood affected by poverty and such poverty correlates as single parenthood, ethnicity, and maternal education? Second, what are the developmental consequences of the duration and timing of family economic deprivation? And, third, what is the comparative influence of economic deprivation at the family and neighborhood level? We investigate these issues with longitudinal data from the Infant Health and Development Program. We find that family income and poverty status are powerful correlates of the cognitive development and behavior of children, even after accounting for other differences—in particular family structure and maternal schooling—between low- and high-income families. While the duration of poverty matters, its timing in early childhood does not. Age-5 IQs are found to be higher in neighborhoods with greater concentrations of affluent neighbors, while the prevalence of low-income neighbors appears to increase the incidence of externalizing behavior problems.  相似文献
