Towards Lessening Learners’Aversive Emotions and Promoting Their Mental Health:Developing and Validating a Measurement of English Speaking Demotivation in the Chinese EFL Context

While a plethora of studies has been conducted to explore demotivation and its impact on mental health in second language(L2)education,scanty research focuses on demotivation in L2 speaking learning.Particularly,little research explores the measures to quantify L2 speaking demotivation.The present two-phase study attempts to develop and validate an English Speaking Demotivation Scale(ESDS).To this end,an independent sample of 207 Chinese tertiary learners of English as a Foreign Language(EFL)participated in the development phase,and another group of 188 Chinese EFL learners was recruited for the validation of the scale.Exploratory Factor Analysis(EFA)and Confirmatory Factor Analysis(CFA)were employed to determine the factor structure of the scale.The EFA results revealed a six-factor solution with Teacher-related Factors in Learning Spoken English(TFLSE),Interest and Valence in Learning Spoken English(IVLSE),Self-efficacy in Learning Spoken English(SELSE),Negative Peer Influence in Learning Spoken English(NPILSE),Undesirable Environment for Learning Spoken English(UELSE),and Negative Influence of Assessment and Learning Materials in speaking class(NIALM).In the validation phase,Confirmatory Factor Analysis(CFA)was performed to validate the internal structure of the scale.The CFA results showed that the model fits the data well.Overall,the ESDS is a robust and trustworthy psychometric tool that could be utilized to examine L2 speaking demotivation.Implications for diminishing EFL learners’demotivation,lessening their aversive emotions and promoting their mental health are also discussed.

Feasibility and simulation model of a pilot scale membrane bioreactor for wastewater treatment and reuse from Chinese traditional medicine

The lack and pollution of water resource make wastewater reuse necessary. The pilot scale long-term tests for submerged membrane bioreactor were conducted to treat the effluents of anaerobic or aerobic treatment process for the high-strength Chinese traditional medicine wastewater. This article was focused on the feasibility of the wastewater treatment and reuse at shorter hydraulic retention time （HRT） of 5.0, 3.2 and 2.13 h. MLSS growth, membrane flux, vacuum values and chemical cleaning periods were also investigated. The experimental results of treating two-phase anaerobic treatment effluent demonstrated that the CODfilt was less than 100 mg/L when the influent COD was between 500-10000 mg/L at HRT of 5.0 h, which could satisfy the normal discharged standard in China. The experimental results to treat cross flow aerobic reactor effluent demonstrated that the average value of CODfilt was 17.28 mg/L when the average value of influent COD was 192.84 mg/L at HRT of 2.13 h during 106 d, which could completely meet the normal standard for water reuse. The maximum MLSS and MLVSS reached 24000 and 14500 mg/L at HRT of 3.2 h respectively. Membrane flux had maximal resume degrees of 94.7% at vacuum value of 0.02 MPa after cleaning. Chemical cleaning periods of membrane module were 150 d. A simulation model of operational parameters was also established based on the theory of back propagation neural network and linear regression of traditional mathematical model. The simulation model showed that the optimum operational parameters were suggested as follows： HRT was 5.0 h, SRT was 100 d, the range of COD loading rate was between 10.664-20.451 kg/（m3.d）, the range of MLSS was between 7543-13694 mg/L.

Measurement invariance and latent mean differences of the Chinese version physical activity self-efficacy scale across gender and education levels

Background: Self-efficacy has been identified as an important determinant of youth's behavior change including physical activity(PA) participation. However, the dimensionality check of a PA self-efficacy scale has rarely been conducted in China. The current study aims to examine(1) the unidimensionality of a shortened Chinese version of PA self-efficacy scale(S-PASESC);(2) the measurement invariance of S-PASESC across gender and levels of education;(3) the latent factor mean difference between gender and levels of education;(4) the direct effects of self-efficacy on PA by different gender and education levels; and(5) the comparisons of the direct effects of self-efficacy on PA across gender and education levels.Methods: The participants were 5 th through 11 th grade public school students recruited from 7 cities located in different geographic regions of China. The final data include a total of 3003 participants(49.7% boys) who have completed the scales.Results: Confirmatory factor analysis(CFA) test supported the unidimensionality of S-PASESC. The S-PASESC is invariant across gender and 3 levels of education at both configural, full metric, and full scalar levels. Findings from latent mean comparisons showed that boys reported higher PA self-efficacy than girls. Students' perceived PA self-efficacy tend to decrease from elementary to high school. Finally, self-efficacy positively related to PA by groups of different gender and education levels and the relationship between self-efficacy and PA is stronger among middle school boys than girls.Conclusion: Findings suggest S-PASESC is a valid scale for measuring Chinese students' PA self-efficacy.

Estimation of Dynamic VaR in Chinese Stock Markets Based on Time Scale and Extreme Value Theory

The accuracy and time scale invariance of value-at-risk （VaR） measurement methods for different stock indices and at different confidence levels are tested. Extreme value theory （EVT） is applied to model the extreme tail of standardized residual series of daily/weekly indices losses, and parametric and nonparametric methods are used to estimate parameters of the general Pareto distribution （GPD）, and dynamic VaR for indices of three stock markets in China. The accuracy and time scale invariance of risk measurement methods through back-testing approach are also examined. Results show that not all the indices accept time scale invariance; there are some differences in accuracy between different indices at various confidence levels. The most powerful dynamic VaR estimation methods are EVT-GJR-Hill at 97.5% level for weekly loss to Shanghai stock market, and EVT-GARCH-MLE （Hill） at 99.0% level for weekly loss to Taiwan and Hong Kong stock markets, respectively.

A Study on the Application of the Chinese English Competence Scale in College English Teaching

The results of the assessment of College Students'English Reading Comprehension Scale based on the Chinese EnglishCompetence Scale show that the assessment of language competence scale can diagnose English teaching and learning in HigherVocational colleges. In order to construct the scale of Chinese college students'ability to speak and act in English, we should ensurethe universality, representativeness and authority of the source of descriptive language and the accuracy, clarity, conciseness,independence and affirmation of descriptive language. Learners can also use the scale to self-evaluate and establish their ownlearning goals. At the same time, the learning time required for each stage is not the same. The learner should determine his ownlearning plan according to his own situation and the standard reference provided by the scale. Its ability grading reflects thecorrespondence between the English level of students in each scholastic school and the ability to describe the descriptors, and it istargeted and instructive for college English teaching. In order to continuously improve the learning effect of college Englishteaching.

A meta-analysis of Chinese herbal medicines for vascular dementia

OBJECTIVE： To investigate the efficacy and safety of Chinese herbal medicines in the treatment of patients with vascular dementia. DATA RETRIEVAL： We retrieved publications from Cochrane Library （2004 to July 2011）, PubMed （1966 to July 2011）, the Chinese Science and Technique Journals Database （1977 to July 2011）, the China National Knowledge Infrastructure （1979 to July 2011）, Google Scholar （July 2011）, and the Chinese Biomedical Database （1977 to July 2011） using the key words ＂Chinese medicine OR Chinese herbal medicine＂ and ＂vascular dementia OR mild cognition impair OR multi-infarct dementia OR small-vessel dementia OR strategic infarct dementia OR hypoperfusion dementia OR hemorrhagic dementia OR hereditary vascular dementia＂. SELECTION CRITERIA： Randomized controlled trials comparing Chinese herbal medicines with placebo/western medicine in the treatment of patients with vascular dementia were included. Diagnostic standards included Diagnostic and Statistical Manual of Mental Disorders-IV, and National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherche et I＇Enseignement en Neurosciences. Two participants independently conducted literature screening, quality evaluation and data extraction. The quality of each trial was assessed according to the Cochrane Reviewers＇ Handbook 5.0. MAIN OUTCOME MEASURES： Effective rate, Mini-Mental State Examination scores, Hasegawa Dementia Scale scores, and incidence of adverse reactions. RESULTS： We identified 1 143 articles discussing the effects of Chinese medicine on vascular dementia. Thirty-one of these were included in the analysis. These studies involved a total of 2 868 participants （1 605 patients took Chinese medicine decoctions （treatment group）; 1 263 patients took western medicine or placebo）. The results of our meta-analysis revealed that Chinese herbal remedies in the treatment group were more efficacious than the control intervention （relative risk （RR） = 1.27; 95% confidence interval （C/）： 1.18-1.38, P 〈 0.01）. Mini-Mental State Examination scores were higher in patients taking Chinese herbal medicines than in those in the control group （weighted mean difference （WMD） = 2.83; 95%CI： 2.55-3.12, P 〈 0.01）. Patients in the treatment group showed better disease amelioration than those in the control group （Hasegawa Dementia Scale scores; WMD = 2.41, 95%CI： 1.48-3.34, P 〈 0.01）. There were also considerably fewer adverse reactions among those in the treatment group compared with those in the control group （RR = 0.20, 95%CI： 0.08-0.47, P 〈 0.01）. CONCLUSION： Chinese herbal medicine appears to be safer and more effective than control measures in the treatment of vascular dementia. However, the included trials were generally low in quality. More well-designed, high-quality trials are needed to provide better evidence for the assessment of the efficacy and safety of Chinese medicines for vascular dementia.

Prosodic Modification of Chinese Speech Based on Sinusoidal Model

Modification on time scale and pitch scale of Chinese syllable based on sinusoidal model is presented in this paper. Firstly, the short term speech is decomposed into a sum of sinusoidal waves of different magnitudes and phases. Then vocal tract system and excitation are obtained using a homomophic technique. Lastly, the speech with desired time scale and pitch scale is obtained through the change of frequency and phase of excitation while the parameters of vocal tract system are changed accordingly. The results show that the adjustable scale of pitch and time scale is big using this algorithm and it is suitable to be used in analysis and synthesis of Chinese speech.

Intercultural Competence Development of Chinese Students After a Short-Term Study Abroad Experience

This study investigated Chinese students’ intercultural competence and linguistic growth during a six-week study abroad program. The students and their professor participated in pre- and post-tests covering written and oral language competency as well as intercultural competence. The Global Scale of English assessed student language development to determine linguistic growth and the Assessment of Intercultural Competence of Chinese College Students (AIC-CCS) was used to determine student growth of intercultural competence skills, specifically related to cultural knowledge, skills, attitudes, and awareness as a result of their experiences in a non-Western context. Results indicated that students experienced a change in the salience of intercultural knowledge themes over their period abroad, as well as improved their individual language abilities. This study provides suggestions for future programming focused on the development of Chinese student intercultural competencies during short-term study abroad experiences in Western university environments.
