Governments often see it as their responsibility to support cultural life and at times spend a significant amount of resources
in the pursuit of this goal. The present article analyses whether and how municipalities influence each other in this decision
to spend resources on the arts (using data on local government cultural spending in 304 Flemish municipalities in 2002). Following
‘central place theory’, the focal point of the analysis is the idea that––especially for cultural expenditures––large municipalities
(and, specifically, ‘central places’) may affect their neighbours’ behaviour differently than small municipalities. The empirical
analysis supports this idea. Indeed, we show that Flemish municipalities’ cultural spending is generally positively affected
by that in neighbouring municipalities. This pattern is, however, significantly more complex for municipalities neighbouring
the 13 largest Flemish cities.

Is syllable segmentation developmentally constrained by consonant sonority within syllable boundaries in silent reading? Evidence in French children 下载免费PDF全文
Norbert Maïonchi‐Pino Bruno de Cara Jean Écalle Annie Magnan 《Journal of Research in Reading》2015,38(3):226-248
There is agreement that French typically reading children use syllable‐sized units to segment words. Although the statistical properties of the initial syllables or the clusters within syllable boundaries seem to be crucial for syllable segmentation, little is known about the role of consonant sonority in silent reading. In two experiments that used audio‐visual and visual pseudoword recognition tasks with 300 French typically developing children, we showed a progressive increase in the use of syllable segmentation from the first through fifth years of reading instruction. The children were influenced both by an optimal ‘sonorant coda–obstruent onset’ sonority profile and by the individual position‐dependent consonant sonority within syllable boundaries. Orthographic and phonological statistical properties did not clearly modulate the response patterns. We provide innovative data to help further understand the developmental course of the use of syllable segmentation as determined by sonority. We discuss our results in the light of linguistic principles. 相似文献

Effect of physiological harvest stages on the composition of bioactive compounds in Cavendish bananas 总被引:1,自引:0,他引:1

The combined influence of maturation, ripening, and climate on the profile of bioactive compounds was studied in banana (Musa acuminata, AAA, Cavendish, cv. Grande Naine). Their bioactive compounds were determined by the Folin-Ciocalteu assay and high-performance thin layer chromatographic (HPTLC) method. The polyphenol content of bananas harvested after 400 degree days remained unchanged during ripening, while bananas harvested after 600 and 900 degree days exhibited a significant polyphenol increase. Although dopamine was the polyphenol with the highest concentration in banana peels during the green developmental stage and ripening, its kinetics differed from the total polyphenol profile. Our results showed that this matrix of choice (maturation, ripening, and climate) may allow selection of the banana (M. acuminata, AAA, Cavendish, cv. Grande Naine) status that will produce optimal concentrations of identified compounds with human health relevance. 相似文献

The African Virtual University (AVU) is attempting to address the huge and unmet demand for educational services in Africa and presents the experiences, lessons, and adjustments being made to achieve improved effectiveness and relevance. This university seeks to address these issues by harnessing the power of modern information and communications technologies (ICTs) to provide cost-effective education and training. AVU is the only institution offering technology-based distance education for the whole continent and has a first-mover advantage. The intervention of the African Virtual University will result in increased access to quality education, improve access to quality literature internationally, and enhance interaction among African academics and between them and the rest of the world. 相似文献

This paper investigates the potential of international youth football tournaments for youth development in the Global South. The tournaments under study were East Africa Cup in Tanzania, and Norway Cup in Norway. Through qualitative interviews with tournament participants, we addressed the following research question: What are the participant’s views of the potentials of Norway Cup and East Africa Cup in dealing with development issues facing youth in the Global South? Our findings demonstrate that all interviewees consider the tournaments potentially beneficial for youth development in the Global South. In the analysis, we identified four different categories, mostly representing positive outcomes of tournament participation. We argue that a functionalist neo-liberal notion of sport is visible in the data material. Thus, our findings correspond with Sport for Development and Peace (SDP) research showing how reproductions of the SDP functionalist discourse ‘continue to be leveraged through sport and sealed into the success story of SDP’. 相似文献

Providing low cost, high quality educational services to growing numbers of multilingual communities is perhaps one of the greatest challenges facing large urban school districts. In the Los Angeles urban area, adult students who wish to attend English as a Second Language (ESL) classes are presently constrained by the limitations of school resources, public transportation and growing levels of crime and street violence. Urban distance learning programmes may provide the best alternative to meet the educational needs of Limited English Proficient (LEP) adult students because it can service large numbers of students who are separated from their schools by geographical distance, safety, convenience, transportation, etc. Using perceptual mapping and conjoint analysis methodologies, this study analytically identifies and examines the design features or attribute characteristics of an ESL urban distance learning programme for LEP adults. Using focus groups as the basis to identify these attributes, perceptual mapping methods point to a market niche in developing technology‐driven, low‐cost distance learning programmes for these students. A conjoint analysis survey finds that LEP students generally favour distance learning programmes where ‘cost’, ‘effectiveness’ and ‘assessment’ are the primary attribute components. 相似文献

The blind-hole method is the most widely used approach to experimentally determine the distribution of residual stress. This paper aims to improve test accuracy of welding residual stress and conducts an experimental study on the strain release factors involved when using the blind-hole method for Q235 and Q345, two steels commonly used in building structures. The ranges of strain release factors A and B in the elastic stage, the effects of strain release factors on residual stress calculated values, and the plastic corrected strain release factors are analyzed considering of the effect of plastic deformation around the blind hole on measurement accuracy. Finally, a simplified calculation formula to determine strain release factors is proposed for use with the blind-hole method. Results show that in the elastic stage, strain release factor A for Q235 and Q345 ranges from-0.399 to-0.525 and strain release factor B from-0.791 to-0.960. Changing the strain release factors A and B shows that calculated residual tensile stress varies in relation to a decrease in both factor values. However, there is a increase in calculated residual compressive stress with a decrease in the strain release factor A value, but there is an decrease with a decrease in strain release factor B value. Calculated residual stress applied to elastic strain release factors is compared with that applied to amended plastic strain release factors for Q235 steel. The maximum deviation between calculated residual stress and test stress is reduced from 21.1 to 1.0%,and for Q345 steel from 26.5 to 1.2%. It is thus evident that the plastic correction formula proposed in this paper can be used in calculations when conducting a residual stress test. 相似文献

We present, in this article, an investigation about the potential of the relationship between formal and non-formal educational environments. Therefore it is not an empirical research, but an essay on the topic. This paper demonstrates the concept that science education and science outreach can be privileged by actions that are developed by closer relations between formal and non-formal places. Currently, non-formal environments such as museums and science and technology centres are considered potential educational resources within the reach of schools. Educators from museums have conducted studies which demonstrate a predominant model of the utilization of these institutions by teachers, which consists of illustrative visits during the exhibitions, but does not feature a collaborative relationship or partnership between schools and these institutions. In Brazil, the main examples of approaches to collaboration between these places and schools have been taking place through the initiatives of teachers or through projects developed by the educational sector, aiming to broaden the dialogue between their institutions and the school community. Another approach mechanism relates to research and extension projects developed by university researchers, sponsored by state and federal funding agencies. In this case, the universities and university museums appear as new social actors that stand in the way of the schools and the cultural environments, complicating the relationship and, at the same time, bringing new questions to the field of educational research. We believe that the discourse in this paper should bring about further discussions in the initial teacher training courses to contribute to the understanding of practices related to the extension of the field of activity of the school. 相似文献
