基于消费者低碳偏好的供应链碳减排策略     

熊榕  梁承姬  韩婷婷 《上海海事大学学报》2019,40(4):52-60

针对一个占主导地位的零售商和两个制造商(名牌产品和普通产品制造商)组成的二级供应链,考虑制造商之间的定价顺序和低碳偏好消费者对普通产品的接受度,分别构建普通产品制造商采用或不采用减排技术情景下的收益模型,得出各情景下最优零售价格和收益。研究发现:零售商选择销售哪种产品与顾客对普通产品的接受度有关;普通产品制造商的减排策略主要取决于减排成本。在相同减排策略下,若顾客对普通产品接受度较大,制造商同时定价时产品的最优零售价小于等于不同时定价时产品的最优零售价,而同时定价时制造商的最优收益大于等于不同时定价时的最优收益,因此两个制造商应同时定价以获得更大的收益。  相似文献   

Syllable-based reading improvement: Effects on word reading and reading comprehension in Grade 2     

《Learning and Instruction》2020

This study examined the effects of a syllable-based reading intervention for German second graders who demonstrated difficulties in the recognition of written words. The intervention focused on fostering word reading via syllable segmentation. The materials consisted of the 500 most frequent syllables typically read by 6- to 8-year-old children. The aims were to practice phonological recoding, consolidate orthographic representations of syllables, and routinize the access to these representations. Compared to children randomly assigned to a wait-list group, poor readers in the treatment condition showed significant improvements in standardized measures of phonological recoding, direct word recognition, and text-based reading comprehension after the 24-session intervention. Poor readers in the treatment condition also showed greater improvements in development of word recognition compared to children with efficient word recognition skills. The results provide evidence that a syllable-based reading intervention is a promising approach to increase struggling readers’ word recognition skills, which in turn will improve their reading comprehension.  相似文献   

Closing the gap: supporting literacy through a computer-assisted-reading-intervention     

Kerry Vincent 《Support for Learning》2020,35(1):68-82

Schools in England are expected to ‘close the gap’ for a range of vulnerable pupils who are achieving below the levels seen amongst their same-aged peers. They are also highly accountable for additional funding that is provided to support this goal. The project reported here involved collating and analysing a range of data in order to evaluate the impact of a widely used computer-assisted-reading-intervention (CARI). Sixteen primary school pupils, all of whom were identified by their school as underachieving in literacy, used the CARI daily over a five-week period. The post-intervention data showed some clear gains in reading and spelling skills for all bar one of the children. The findings are discussed in relation to the wider literatures on CARIs. The research concludes that the CARI under investigation offers a useful and cost-effective adjunct to whole-class and group reading instruction and may be particularly beneficial for supporting the learning of pupils who are struggling to consolidate the knowledge and skills covered in their regular classroom reading instruction.  相似文献

朱熹读书法版本辨析及其对阅读推广的启示     

朱原谅 《图书馆杂志》2020,(4):50-56,61

掌握古代先贤的读书方法有助于提升目前阅读推广的有效性。通过文献研究法,发现流传的朱熹读书法三个版本源自黄士毅的《朱子语类》、黎靖德的《语类大全》和张洪、齐熙编辑的辅广《朱子读书法》,其内容和编辑思想各不相同。朱熹读书法中蕴含的读书于学者至为重要、读书不在多寡而在于"精"、读书须循序渐进、读书有利于崇德、作文是读书的重要目标等思想对当前阅读推广活动实践、阅读推广人和读者的素养提升都有很高的参考价值。  相似文献

融资约束、税收激励与企业研发投入——来自中国制造业上市公司的证据     

水会莉  韩庆兰 《科技管理研究》2016,(7):30-36

以中国制造业上市公司2011—2013年的数据为样本,研究融资约束与税收激励2个因素对企业研发投入的影响。研究发现,融资约束显著影响企业研发投入强度,民营企业研发投入主要依赖于债务融资,国有企业的研发投入主要取决于股权融资;税收政策对企业研发投入的激励效应主要体现在民营企业,对国有企业研发投入的促进作用不显著;税收激励效应有效缓解了融资对民营企业研发投入的影响,企业所得税税收政策较增值税更能促进民营企业的研发投入。  相似文献   

Externalizing behavior problems and interest in reading as predictors of later reading skills and educational aspirations     

《Contemporary educational psychology》2017

This study examined the developments in children’s externalizing problems and interest in reading during their first four years of school (Grades 1–4) and investigated whether this development predicted the children’s Grade 6 reading skills and educational aspirations. Data comprised (1) teachers’ ratings of externalizing problems and children’s (N = 642; 43% girls) self-ratings of their interest in reading, collected between Grades 1 and 4, and (2) measures of reading fluency and comprehension, and children’s self-reports of educational aspirations, collected at Grade 6. First, latent growth modeling showed that a higher level of externalizing problems in Grade 1 was associated with a lower concurrent interest in reading. Second, a positive association between the initial level of interest in reading and a linear change in externalizing problems indicated that children with a lower interest in reading in Grade 1 were rated by teachers as exhibiting higher levels of externalizing problems, which nonetheless declined over the course of their first four years of school more than among other children. Third, a higher initial level of externalizing problems with a linear change in these problems across Grades 1–4 was a predictor of lower subsequent educational aspirations and poorer reading comprehension in Grade 6. Analysis of the indirect effects indicated that a higher level of externalizing problems was associated with a lower concurrent interest in reading, which, in turn, was related to poorer future reading fluency and lower educational aspirations. The findings imply that problem behaviors are interlinked with academic skill development and motivation across the first six years of school.  相似文献   

Development of students’ text-picture integration and reading competence across grades 5–7 in a three-tier secondary school system: A longitudinal study     

《Contemporary educational psychology》2017

375 students from 24 randomly selected classes of a three-tier secondary school system were tested in a longitudinal study for their text-picture integration and pure reading competence as well as verbal and spatial intelligence at grades 5–7. Data were analyzed according to the integrated model of text and picture comprehension using hierarchical linear modeling techniques. Results indicate that text-picture integration comprises higher spatial cognitive demands than pure reading. School tiers differed in terms of competency levels, but also in terms of growth rates of text-picture integration competence. Differences between lower tiers and higher tiers for text-picture integration competence became smaller from grade to grade, whereas developmental trajectories of reading competence ran parallel to each other. The study reveals that the skills for the conjoint processing of text and pictures develop in a way that might help especially poorer students in lower school tiers to catch up with their mates in higher tiers as compared to the competence of pure reading. Text-picture integration seems to provide gradually better opportunities for less capable learners to compensate for previous lags in their learning.  相似文献
