The Role of Positive and Negative Emotions in Resilience Among L2 Learners: A Three Level Meta‐Analytic Review

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Second/foreign language (L2) learning is not solely a cognitive/linguistic acquisition process but includes mixed emotional experiences. Understanding how these emotional experiences relate to resilience could help our understanding of how learners navigate fluctuations in emotions when learning an L2.

A Latent Profile Analysis of Chinese EFL Students’ Speaking Self‐Efficacy: The Role of Gender in Predicting Profile Membership and the Association of Profiles With Speaking Proficiency

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Understanding learners’ English speaking self‐efficacy is essential for promoting effective oral communication in EFL contexts. However, variable‐centered research on English speaking self‐efficacy often overlooks heterogeneity among learners.

关于丢番图方程x⁴-pqy²=1（Ⅱ）

四川大学学报. 自然科学版, 1980
3.方程(1)在p≡17(mod24),q≡3(mod8)或p≡5(mod24),q≡23(mod24)或p≡5(mod24),q≡3(mod8),(p/q)=1时均无正整数解.4.当D=2p时,方程(1)除开有解p=3,x=7,y=20外,无其他的正整数解.5.方程(1)在p≡3(mod4),q≡3(mod4)时无正整数解.国外,Nagell,Ljunggren,Cohn等人有过不少工作,可参看文[4]所附文献.本文用不同于前面诸文的方法,对于D=pq的情形,得到进一步的结果 ...

What Contributes to Self‐Efficacy in Speaking Chinese as a Foreign Language: A Social Cognitive Perspective

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Grounded in social cognitive theory, this study investigated how high‐evidence factors jointly contribute to Chinese‐as‐a‐foreign‐language (CFL) speaking self‐efficacy. Data from 236 CFL learners in Beijing revealed a multifaceted pattern of associations.

换位棋问题规则的表征与解题正确率间关系的研究

, 1997
本研究通过对被试求解换位棋过程的记录与分析，重点研究了问题表征在换位棋求解过程中的作用。实验结果表明：（1）正确表征问题规则是解题的必要前提.对问题规则信息的误解和遗漏，是影响解题正确率的重要因素。其中对非隐含问题规则的错误表征也占全部错误表征的很大比率。（2）“关键结构”的发现是解决换位棋的必要条件，对问题规则的错误表征影响“关键结构”的发现.（3 ...

关于方程sum from j=0 to h（x+j）ⁿ=（x+h+1）ⁿ

四川大学学报. 自然科学版, 1978
我们曾证明6≤n≤33时,（1）无正整数解,以及其他若干结果。P.Erd?o对于x=1的情形,曾猜测（1）除开1+2=3外,无其他正整数解,L.Moser证明了这个猜测在h+2≤1010～6时成立。本文将证明:方程（1）在n是奇数时,除开已知的n=3,h=2,x=3和n=h=x=1外无其他正整数解,这个证明初等而简短。运用这个方法还可证明在2β|n,h（?）1,2(mod2β+3),β>0或n=2s,3·2s,s>1时,（1）均无正整数解。
