郭沫若早期诗学与与西方文艺美学思潮（二题）          下载免费PDF全文

伍世昭 《惠州学院学报》2003,23(4):34-39

文章运用比较诗学的方法，对郭沫若早期诗学与弗洛伊德精神分析美论和柏格森生命美学的影响／接受关系进行了讨论。文章认为，郭沫若早期对这两种思潮的接受都不是照单全收的，由于时代(现实)与文化传统的制约，再加上西方不同思潮的交叉影响，这两种思潮在郭沫若那里均已发生了这样那样的改变，这种改变隐含了诗学建构的某些规律性现象。文章以郭沫若早期对上述两种思潮的接受为个案，探讨的其实是一种新型诗学何以建构的问题。  相似文献

Development of a chemically defined medium for Planctopirus limnophila to increase biomass production     

《Electronic Journal of Biotechnology》2021

BackgroundPlanctomycetes is a phylum of biofilm-forming bacteria with numerous biosynthetic gene clusters, offering a promising source of new bioactive secondary metabolites. However, the current generation of chemically defined media achieves only low biomass yields, hindering research on these species. We therefore developed a chemically defined medium for the model organism Planctopirus limnophila to increase biomass production.ResultsWe found that P. limnophila grows best with a 10 mM sodium phosphate buffer. The replacement of complex nitrogen sources with defined amino acid solutions did not inhibit growth. Screening for vitamin requirements revealed that only cyanocobalamin (B12) is needed for growth. We used response surface methodology to optimize the medium, resulting in concentrations of 10 g/L glucose, 34 mL/L Hutner’s basal salts, 23.18 mM KNO₃, 2.318 mM NH₄Cl and 0.02 mg/L cyanocobalamin. The analysis of amino acid consumption allowed us to develop a customized amino acid solution lacking six of the amino acids present in Aminoplasmal 10%. Fed-batch cultivation in a bioreactor using the optimized medium achieved a final ΔOD₆₀₀ of 46.8 ± 0.5 after 108 h, corresponding to a cell dry weight of 13.6 ± 0.7 g/L.ConclusionsThe optimized chemically defined medium allowed us to produce larger amounts of biomass more quickly than reported in earlier studies. Further research should focus on triggering P. limnophila biofilm formation to activate the gene clusters responsible for secondary metabolism.How to cite: Kruppa OC, Gerlach D, Fan R, et al.

Exploring Developmental Appropriateness of Multitouch Tables in Prekindergarten: A Video Analysis     

Jennifer Ward  Stephanie Branson  Megan D. Cross  Ilene R. Berson 《Journal of Research on Technology in Education》2016,48(3):227-238

This study explored how developmentally appropriate practices influenced the affordances of a multitouch surface in an early childhood classroom. Children, ages 4 to 5 years old, were videotaped while engaged in a storymaking application on a multitouch table. As a result of the study, we found that some challenges with the functionality undermined children's autonomous control. The researchers observed numerous instances of issues with control of the medium, including height of the table, sensitivity to multiple types of touch, and limited instructions and prompts. Implications for future research and practice are discussed.  相似文献   

Children's responses to the interactivity of storybook apps in family shared reading events involving the iPad          下载免费PDF全文

《Literacy》2017,51(1):44-52

This paper reports on some data on the effects of screen‐based interactivity on children's engagement with storybook apps during family shared book reading that were gathered in a 2‐year, small‐scale ethnographic case study in Spain. Data analysis focuses on the complex interplay between the storybook app's interactive features and the children's responses to them. Our findings show that interactive elements increase the child's autonomy, as they tend to promote the importance of the reader, positioning him or her as a collaborator, storyteller, an author or an internal character in the fiction; something that can materialise in exciting narrative strategies that can trigger powerful responses to digital literary texts in emergent readers, including playing, creating new fictions or engaging emotionally with the story. Finally, we argue that the Reader Response models that have been used over recent decades to understand children's reading experiences with storybooks need to be revised to better understand their current experiences with interactive texts.  相似文献   

Is Reading Recovery sustainable two to four years after discontinuation?     

Karen Nicholas 《Education 3-13》2013,41(6):663-672

The Reading Recovery programme has been a key early literacy intervention in many international contexts for over two decades. As a consequence, there have been numerous investigations into its efficacy for short-term gains, but only a few on long-term sustainability. This study examines the progress of 95 Year 4–6 students from seven schools in the rural hinterland of New Zealand. Standardised data were collected from students who had been successfully discontinued from Reading Recovery two to four years previously and compared them with mean performance from the same school populations. Results showed that only Year 6 students obtained the mean scores which placed them within the national average range. Our results also showed that whilst almost half of the ex-Reading Recovery students we studied, fell within the average band, 45% were classified as well below average.  相似文献   

Assessment in special schools: national early assessment procedures and pupils attending special schools in England     

Ann Lewis  Geoff Lindsay  Emma Phillips 《欧洲特需教育杂志》2013,28(2):141-153

An implicit assumption that fostering inclusion means having shared systems encompassing the needs of all children is evident in many aspects of policy development over the past decade. Reflecting this, the implementation of ‘baseline assessment’ schemes (i.e. testing at around age 5 years) is a statutory requirement on all state-maintained special and mainstream schools in England since 1998. Our argument is that the enthusiasm for commonality has obscured the need to question the value and validity of baseline assessment schemes for children with special educational needs (and possibly some others such as children having English as an additional language). We illustrate this position with reference to data from our recent study on baseline assessment in England. The study encompassed survey data from a national sample of 982 schools, of which 107 were special schools. Between them, these special schools used 42 different baseline assessment schemes. Comparisons between our mainstream and special school respondents indicated that there were similarities in the nature and perceived value of the schemes used. However, special schools were less satisfied with their schemes. We suggest that a reappraisal of the nature and purpose of baseline assessment for pupils with special educational needs warrants greater critical debate. Without this, there is a danger that a stress on commonality, veiling an inclusion orthodoxy, will ultimately be counterproductive.  相似文献   

大学自由教育的生成逻辑与实践路径探析     

张琳琳 《成都航空职业技术学院学报》2019,35(2):25-28

自由教育时常被冠以自由主义教育的标签,但其精神实质与当前我国倡导的“学生发展核心素养”教育异曲同工,应该得以澄清。自由教育在国家层面上与社会主义本质及核心价值观的全面发展一致,在社会层面上与科教强国的创新驱动一致,在个人层面上与人才培养的人文关怀一致。因此,高校应该把自由教育与人才培养相结合、把自由教育与创新教育相结合、把自由教育与个人成长相结合。  相似文献
