The Changing Nature of Non-formal Education in Latin America     

Thomas J. La Belle 《比较教育学》2000,36(1):21-36

This article highlights the history of innovation and creativity in non-formal education programming in Latin America since the 1920s. These include community-based programmes, literacy, fundamental education, community development, technical vocational training, extension education, consciousness raising, popular education, and community schooling. With the economic downturn in the 1980s, non-formal education became less viable as part of socio-economic development strategies owing partly to the social progress made in the region, a shift to schooling as a priority and the pulling back of governments from social service funding. Nevertheless, the 1980s saw the informal economy and social movements as emerging avenues for non-formal education programming and non-governmental agencies became the dominant vehicle for educational delivery. During the 1990s, technical education was going through privatisation and adult basic education was being criticised and overhauled. Citizenship education, a potential avenue for non-fomal education investment in the newly democratised region is identified as an area overlooked by policy makers. Similarly, the growing needs of the indigenous populations of the region and urban youth unemployment are singled out as potential areas for non-formal education programming.  相似文献   

Criterion-related validity of self-report walking time from the EPIC questionnaire in older adults

Tools for measuring walking time make use of objective and subjective methods. One subjective approach is to administer physical activity questionnaires (PAQ), mainly because they are inexpensive and easy to give to large groups. The European Prospective Investigation into Cancer and Nutrition (EPIC) study has a brief PAQ (EPIC-PAQ) and includes one question referencing walking time. The objective of this study was to assess the validity of the question about time spent walking included in the EPIC-PAQ.

The sample included 200 older adults (113 women). To assess daily walking time, participants responded to the EPIC-PAQ in an interview and wore a portable gait analysis system and physical activity monitor for 48 consecutive hours in free-living condition.

Results indicated that the mean of bias between the EPIC-PAQ and objetive measurement was ?64.6 min/day. Also, the correlation was low compared to an objective measurement (rho = 0.196) and was positively correlated with the time spent at speeds below 2.5 mph but the correlation was low (slow walking rho = 0.154 and pace walking rho = 0.163).

The EPIC-PAQ shows low correlations with the objective measurement of walking time, that suggests it may be inaccurate and affecting the estimate of the EPIC-PAQ’s PA energy expenditure in this age group.  相似文献

Consolidating properties of Regalrez 1126 and Paraloid B72 applied to wood     

Gino Mirocle Crisci  Mauro Francesco La Russa  Marco Malagodi  Silvestro Antonio Ruffolo 《Journal of Cultural Heritage》2010,11(3):304-308

This study is aimed at an assessment of the properties of two polymeric products applied to Norway spruce (Picea abies) and White poplar (Populus alba) wood species. It contributes to ongoing research experiments on the consolidating properties of two synthetic resins and their potential synergic action on wood, resulting from their different interaction with the substrate: Paraloid B72 and Regalrez 1126. Experiments were carried out on a series of samples of the two wood varieties. The consolidants were applied alone and one after the other, with one coat of Regalrez and then one of Paraloid. Porosity and variations in pore size distribution were ascertained by mercury intrusion porosimetry (MIP). Colorimetric and IR spectroscopic measurements were also taken before and after aging by solar radiation and freeze/thaw cycles, to verify the possible slowing of photodegradation of the treated wood and the consolidating resistance. Results confirm that both products penetrate the wood with a different behaviour. After double treatment with Regalrez + Paraloid, a significant advantage was observed in terms of mechanical resistance and pore size distribution, although no advantages as regards resistance to photo-oxidizing processes or colour changes were observed.  相似文献

Best performances by men and women open-water swimmers during the 'English Channel Swim' from 1900 to 2010     

E Eichenberger  B Knechtle  P Knechtle  CA Rüst  T Rosemann  R Lepers 《Journal of sports sciences》2012,30(12):1295-1301

Abstract Little research has examined ultra-endurance swimming performances. The 'English Channel Swim', where swimmers have to cover a distance of 32?km between England and France represents a unique long-distance, open-water, sea-swimming challenge, and each year swimmers from all over the world try to succeed in this challenge. The best times in minutes and the nationality of successful men and women swimmers were analysed from 1900 to 2010. A total of 1,533 swimmers (455 women and 1,078 men) from more than 40 countries have successfully completed the 'English Channel Swim'. Great Britain was the country most represented, with 38% of the total, followed by the United States with 20%. Swim speed has increased progressively for both sexes (P??0.05). The results suggest that the performance of women open-water ultra-distance swimmers may be similar to that of men. Further studies investigating anthropometrical and physiological characteristics of open-water ultra-swimmers are needed to compare men's and women's open-water ultra-swim performances.  相似文献   

Reading and writing from multiple source documents in history: Effects of strategy instruction with low to average high school writers   总被引：2，自引：0，他引：2  

Susan De La Paz  Mark K. Felton 《Contemporary educational psychology》2010

This study examined the effects of historical reasoning strategy instruction on 11th-grade students. Students learned historical inquiry strategies using 20th Century American history topics ranging from the Spanish-American war to the Gulf of Tonkin incident. In addition, students learned a pre-writing strategy for composing argumentative essays related to each historical event. Results indicate that in comparison to a control group (N = 79), essays written by students who received instruction (N = 81) were longer, were rated as having significantly greater historical accuracy, were significantly more persuasive, and claims and rebuttals within each argument became more elaborated. Importantly, students in the control group read the same primary and secondary source document sets, and received feedback on written essays on the same topics.  相似文献
