The present study investigates the effects of congruency and frequency on adjective-noun collocational processing for Chinese learners of English at two proficiency levels based on the data obtained in an online acceptability judgment *** subject pool of this research included 60 English majors studying at a university in China;30 were selected as a higher-proficiency group and 30 as a lower-proficiency group according to their Vocabulary levels Test(Schmitt et al.,2001)scores and their self-reported proficiency in *** experimental materials were programmed to E-prime 2.0 and included six types of collocations:(1)15 high-frequency congruent collocations,(2)15 low-frequency congruent collocations,(3)15 high-frequency incongruent collocations,(4)15 low-frequency incongruent collocations,(5)15 Chinese-only items,and(6)75 unrelated items for baseline *** collected response times(RTs)and accuracy rates data were statistically analyzed by the use of an ANOVA test and pairwise comparisons through SPSS 16.0 *** results revealed that:(1)the adjective-noun collocational processing of Chinese English learners is influenced by collocational frequency,congruency and l2 proficiency;(2)the processing time is affected by the interaction of congruency and frequency;and(3)the interactive effect of l2 proficiency in conjunction with congruency and frequency also influences the processing quality.

Dear Editor:Brain metastasis(BM)has long been recognized as a prognostic factor associated with poor prognosis for non-small cell lung cancer(NSClC)in the era of con-ventional chemotherapy and targeted therapy[1].In the era of immunotherapy,controversial findings have been reported regarding the prognostic significance of BM in patients with NSClC treated with programmed death-1/programmed death-ligand 1(PD-1/PD-l1)inhibitors.

Benefiting from the rapid development of environmental DNA (eDNA) technologies,sedimentary DNA (sedDNA)emerges as a promising tool for monitoring plant compositions in remote *** Tibetan Plateau (TP),renowned for its harsh environment and numerous ponds and lakes,presents a potentially demanding region for the application of sedDNA on vegetation ***,we used the g and h universal primers for the P6 loop region of the chloroplast trn l (UAA)intron to amplify plant DNA in surface sediments from 59 ponds and small lakes on the southwestern *** applicability and limitations of using plant DNA metabarcoding for modern vegetation monitoring and palaeo-vegetation reconstructions have been assessed by comparing sedDNA,pollen,and vegetation survey *** results showed that plant DNA metabarcoding recorded 186 terrestrial taxa,of which 30.1%can be identified at the species *** plant sedDNA approach can effectively disclose the dominant plant taxa (including Asteraceae,Cyperaceae and Poaceae) and significant vegetation assemblages in the vicinity of the investigated *** number of taxa and taxonomic resolution of plant sedDNA exceeded that of pollen analysis(75 taxa detected,5.3%can be identified at species level).Unlike pollen that retains a broad spectrum of regional plant signals(including Pinus and Artemisia),plant sedDNA mirrors very local plants,underscoring its utility in local vegetation monitoring and *** conclude,plant DNA metabarcoding of (small) lake sediments warrant increased attention in the future for local vegetation monitoring and reconstructions on the TP.

采用田野调查法对福建省l村游龙灯组织模式的更迭进行深度考察,提炼出一种趣缘型的民俗体育文化自组织模式,这既是民俗体育文化创造性转化和创新性发展,也是民俗体育文化中国式现代化的积极探索和生动实践。研究提出“改变组织模式,保留核心形式和核心内涵”的民俗体育文化中国式现代化发展路径,这可为具有相似资源禀赋的民俗体育文化提供一种可能的现代化路径选择。最后,从理论上揭示了这种新型组织模式的运行机制,即该组织模式在情感动员机制、合法性机制、技术整合机制和主体内生机制共同作用下生成。
