Learning From Our Mistakes: Improvements in Spelling Lead to Gains in Reading Speed     

Gene Ouellette  Sandra Martin-Chang  Maya Rossi 《Scientific Studies of Reading》2017,21(4):350-357

The present study tested the hypothesis that underlying orthographic representations vary in completeness within the individual, which is manifested in both spelling accuracy and reading speed. Undergraduate students were trained to improve their spelling of difficult words. Word reading speed was then measured for these same words, allowing for a direct evaluation of whether improvements in spelling would bring about faster reading speeds. Results were clear: Spelling accuracy and reading speed were strongly related across and within participants. Most important, words that improved in spelling accuracy were read more rapidly at posttest than words that did not show improvement in spelling. These results provide direct evidence showing that the quality of orthographic representations, as indexed by spelling accuracy, directly relates to reading speed. This is consistent with the lexical quality hypothesis and highlights the relevance of spelling in literacy acquisition.  相似文献   

Effect of antioxidants and exercise on bone metabolism     

Maïmoun L  Simar D  Caillaud C  Peruchon E  Sultan C  Rossi M  Mariano-Goulart D 《Journal of sports sciences》2008,26(3):251-258

We examined the effects of antioxidant supplementation in association with progressive aerobic training on the bone metabolism of healthy elderly individuals. For 8 weeks, 13 participants (mean age 74 years) received vitamin C (500 mg) and vitamin E (100 mg) daily and participated in a supervised progressive aerobic training programme. After the 8 weeks, 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D concentrations were increased significantly by 42.8% (P < 0.001) and 26.8% (P < 0.01) respectively, while parathyroid hormone concentration was decreased by 17.5% (p < 0.05). Of the bone markers, only bone alkaline phosphatase decreased, by 14.6% (P < 0.05). No variation was observed for ionized calcium, insulin-like growth factor-1 or insulin-like growth factor binding protein-3. Our findings suggest that 8 weeks of combined antioxidant supplementation and aerobic training modified vitamin D metabolism and parathyroid hormone concentration. These adaptations might counterbalance the unfavourable hormonal profile frequently observed in the elderly that predisposes them to accentuated age-related bone loss.  相似文献   

Race,Ethnicity, Class and Identity: Implications for Study Abroad     

Federica Goldoni 《Journal of Language, Identity & Education》2017,16(5):328-341

This study addresses study abroad and second language acquisition. The number of U.S. students studying abroad is increasing. However, students’ cultural and linguistic immersion experiences abroad can be disconcerting, challenging their sociocultural identities, values, learning objectives, and expectations. This study employed critical race theory to explore how a Black male student’s race, ethnicity, and class affected his interactions with locals and his language and culture learning, and how his experiences had strong repercussions on his identity negotiation process. The results of this study had strong implications for this student’s full immersion and academic learning. This article concludes with considerations for study abroad programs and how they should address discrimination, racial microaggressions, and racial battle fatigue.  相似文献

Twitter Use During TV: A Full-Season Analysis of #serviziopubblico Hashtag     

Luca Rossi  Fabio Giglietto 《广播与电子媒介杂志》2016,60(2):331-346

Several recent reports pointed out how the practice of using a “second screen” while following a television program is becoming an increasingly widespread phenomenon. When the secondary device is used to read or to comment about a watched program, most of the discussion takes place on popular social media such as Facebook and Twitter. Previous research has shown that the analysis of these contents could lead to a better understanding of the behavior of networked publics and of the structure of the show itself. Nevertheless most of the existing research is focused on the content only and focused on a single episode analysis or on big media events. Leveraging this background, this article presents instead a study focused on the relationships between content and users across an entire airing season of a TV program. Through a quantitative network analysis of the tweets produced during 25 episodes of the Italian political talks show Servizio Pubblico, we identified a small loyal group of viewers. Despite the differences in quantity of content produced, the loyal viewers do not show any sign of forming a community-like structure. We also performed a qualitative analysis of the tweets produced during one specific episode and discussed the elements of the TV show that generated the higher level of engagement on Twitter.  相似文献   

Integrity in UNESCO World Heritage Sites. A comparative study for rural landscapes     

Paola Gullino  Federica Larcher 《Journal of Cultural Heritage》2013,14(5):389-395

Since 2005, Outstanding Universal Value (OUV) is the standard by which United Nations Educational Scientific and Cultural Organization (UNESCO) evaluates world cultural heritage site suitability. The sites worthy of UNESCO preservation as well as the parameters used to demonstrate OUV are diverse. Our study focused on the uniquely distinguished rural landscape sites and the OUV parameter of integrity. Integrity however, is an elusive concept for which UNESCO provides no definitional protocol, and for which the scientific community objects to a static or pure historical interpretation. Given this, our work aims to analyse the concept of integrity and how it can be used to preserve the heritage of rural landscapes. After reviewing the UNESCO approach, we focused on the international scientific debate on the meaning and application of integrity. We designed and conducted a comparative study of UNESCO rural landscapes selected from the 2011 World Heritage List. Documents describing the historical, rural, and agro-ecological features of each of the fourteen rural sites were analysed. From this, several historical and ecological parameters were chosen as “values to have” and several socio-economic and management parameters were chosen as “values to maintain” to assess the integrity of each landscape. Our results found integrity to be a value of both cultural and natural landscapes and that it is key to site identity. We demonstrated that UNESCO assigns a high value to the following parameters: historical features, traditional crops and local products, land-use and agricultural practice permanence, and the presence of architecture related to agricultural activity. Finally, we found the relationship between culture and nature to characterize best the integrity of a rural landscape, rather than nature or culture alone.  相似文献

Educational action research in Singapore: to prove or improve?     

Wah Kiat Tan  Doune Macdonald  Tony Rossi 《Asia Pacific Journal of Education》2009,29(3):357-371

The rise of educational action research amongst schools in Singapore can be attributed to the government's belief that educational research and reform can improve school performance and help Singapore keep pace with the impact of globalization. However, against a backdrop of neo-liberal educational reform where efficiency, accountability and demonstrable outcomes are valued, the underlying intent of the action research projects would seem to be inconsistent with the emancipatory intent normally associated with action research. A systematic review was conducted of 71 action research projects submitted to a local educational conference in 2006. Of concern to us is how action research has been narrowly interpreted and recruited simply as an evaluative tool with the emancipatory potential largely ignored. The paper is theoretically framed by governmentality and performativity to explore the embedded power relations that may “fabricate” the action research projects. The findings and discussions suggest a need for the government, schools and teacher-researchers to reflexively question the current expectation of action research and to be clear about its broader purpose.  相似文献   

Becoming a health and physical education (HPE) teacher: Student teacher ‘performances’ in the physical education subject department office     

Tony Rossi  Karen Sirna  Richard Tinning 《Teaching and Teacher Education》2008

This study considered how physical education teacher education students ‘perform’ their ‘selves’ within subject department offices during the practicum or ‘teaching practice’. The research was framed by a conceptual framework informed by the work of Goffman on ‘performance’ and ‘front’. The findings revealed three common performances across the whole group across all sites. These were: performance of sports talk, bodily performances, and performance of masculine repertoires. Such performances were considered to be inconsistent with the coursework ideals and principles within the teacher education programme but in step with the general ethos of most PE department offices.  相似文献
