5Learning Mandarin in Later Life:Can Old Dogs Learn New Tricks?显示文摘This case study reports on a native English speaker's learning of Mandarin as a 13th language starting at the age of67.The learner,after completing a 150-hour,3-DVD course called Fluenz Mandarin,had 70online sessions with a Chinese-language instructor from a Beijing-based University.The learning content focused mainly on pinyin,a Romanization system for the pronunciation of Standard Mandarin.The sessions contained real-life communication in Chinese based on Chinese sentences produced beforehand by the learner consistent with his life experiences and professional interests as an applied linguist.After the sessions,the instructor developed the sentences into formulated language and kept a detailed log with the learner's feedback as well.Meanwhile,the learner created electronic flashcards for words and phrases to review.The paper considers the impact of advanced age,hyperpolyglot status,and the use of a sophisticated language strategy repertoire on Mandarin learning.The paper reports on the learner's results as viewed from the vantage point of the learner and from that of his instructor as well,paying particular attention to vocabulary(e.g.,the use of measure words and the overabundance of homonyms and near homonyms),grammar(e.g.,word order),and pronunciation(e.g.,the perception and production of the four tones).ANDREW D.COHEN PING LI 2013当代外语研究2013,,12:0
6Metabolic signatures of Arabidopsis thaliana abiotic stress responses elucidate patterns in stress priming,acclimation,and recovery显示文摘Temperature,water,and light are three abiotic stress factors that have major influences on plant growth,development,and reproduction.Plants can be primed by a prior mild stress to enhance their resistance to future stress.We used an untargeted metabolomics approach to examine Arabidopsis thaliana 11-day-old seedling’s abiotic stress responses including heat(with and without priming),cold(with and without priming),water-deficit and high-light before and after a 2-day-recovery period.Analysis of the physiological phenotypes showed that seedlings with stress treatment resulted in a reduction in fresh weight,hypocotyl and root length but remained viable.Several stress responsive metabolites were identified,confirmed with reference standards,quantified,and clustered.We identified shared and specific stress signatures for cold,heat,water-deficit,and high-light treatments.Central metabolism including amino acid metabolism,sugar metabolism,glycolysis,TCA cycle,GABA shunt,glutathione metabolism,purine metabolism,and urea cycle were found to undergo changes that are fundamentally different,although some shared commonalities in response to different treatments.Large increases in cysteine abundance and decreases in reduced glutathione were observed following multiple stress treatments highlighting the importance of oxidative stress as a general phenomenon in abiotic stress.Large fold increases in low-turnover amino acids and maltose demonstrate the critical role of protein and starch autolysis in early abiotic stress responses.Yuan Xu Dana M.Freund Adrian D.Hegeman Jerry D.Cohen 2022Stress Biology2022,2,1:0
