Abstract

In order to increase the competitiveness of Taiwan to international environment, Taiwanese Government has become aware of the importance of English in reforming English education and establishing a new language testing system in leading to more successful language learning. However, many scholars in Taiwan are dubious as to whether this reformed English education has really improved the English communicative ability of learners. The purpose of this study is, therefore, to investigate learners’ communicative competence in terms of communication strategy usage and pragmatic competence, by means of administrating a set of communicative task based activities within a computer mediated environment to provide evidence of the current learning outcomes. The administration of the set of communicative task based activities took place in August 2006. Drawing upon the framework proposed by Bachman (1990), both strategic and pragmatic competence could be identified. After data collection, the learners’ speech data was analysed based on the taxonomy of Poulisse (1993) and the findings revealed that the learners employed the re-conceptualisation strategy more frequently than the substitution strategy. A new strategy, named ‘additional strategy’, was also discovered during this study. By means of adopting the six criteria of pragmatic competence as suggested by Hudson et al. (1995) to score the learners’ responses, the results of learners’ performance were low with no distinct differences between three given speech acts. Based on the coding scheme of Blum-Kulka et al. (1989) and Beebe et al. (1990), it can be suggested that the learners were influenced by Chinese culture which resulted in inappropriate responses to the situations. Therefore, this study suggests that Taiwanese learners of English need to improve their communicative competence, particularly in terms of communication strategies and pragmatic competence. Furthermore, it can be said that it is vital to adopt a communicative task based activity into classrooms in Taiwan to increase opportunities for learners to interact with each other to improve language learning and teaching contexts.

Abstract

This study analyzes the rapid development of mobile payment in the fast-food restaurant industry and the effect it has on consumer behavior. Moreover, this work examines the influence of mobile payment users' motivation on satisfaction and the effects of motivation and satisfaction on continuance intention. A total of 547 questionnaires were collected in Shenzhen China prior to the late 2019 COVID-19 pandemic outbreak. The findings indicate that motivation and satisfaction each has a significant positive, direct effect on the continuance intention of mobile payment usage. The results show that intrinsic motivation, notably the Perceived Enjoyment factor, has a greater impact than satisfaction on continuance intention. Respondents are less satisfied with Perceived Privacy and Perceived Security but show greater satisfaction with Perceived Service Quality. Perceived Enjoyment and Perceived Service Quality can evoke the intention to continue to use mobile payment. The results of this research provide useful information for mobile payment providers and fast-food restaurant owners to further improve their services. The proposed consumer behavior framework of the continuance intention of mobile payment service usage can be used as a basis for hospitality researchers to refine research on mobile payment technology and service management.

23. Toward the development of a general chiral alpha-substituted acetate enolate synthon for aldolization. DMAP- and NEt3-promoted oxazolidinethione 'deacylation.'

Abstract

Research was conducted to prove that acetate titanium enolate obtained from thioimide efficiently effects one-step bromination-aldolization with excellent yields and exceptionally high levels of asymmetric induction in aldol additions. Results demonstrate for the first time the successful use of titanium-mediated bromination-aldolization of N-acetyloxazolidinethione to develop a general chiral alpha-substituted acetate enolate synthon. Findings highlight the unexpected reactivity and stereoselection of bromoacetate titanium enolate aldolizations which offer a practical alternative to the use of other expensive metalloids such as boron to obtain excellent yield and exceptional stereocontrol.

25. A general, highly antistereoselective aldolization method via camphor-derived boryl enolates

Abstract

A common and highly anti-stereoselective aldolization process is exhibited by the reactions of chiral boryl enolates derived from camphor. The yield rate of the reaction is high and depicts a general aldehyde characteristic whereas TiCl4 and SnCl4 catalysts increase the reactivity and diastereoselectivity of aldol bond reactions. This implied the importance of the chiral auxiliary structure in the asymmetric aldol type reactions.

Abstract

This study aimed to develop a Chinese Healthy Eating Index for School-age Children (CHEI-SC), apply it in the 2011 China Health and Nutrition Survey (CHNS) to assess dietary quality, and compared it with our former developed index named CHEI. Data of 3-day 24-hour diet recalls and household food inventory survey from 1600 school-age children in CHNS-2011 were used to develop the CHEI-SC, using the methods of standard portion size, energy-density-based approach, and least restrictive approach. The CHEI-SC included 19 components with a total score (T-score) ranging from 0 to 100. The investigated children had a median score of 49.6. Children with a higher T-score were more likely to have higher social economic status (SES), higher level of urbanisation, fewer family size, and regularly attending school. The CHEI-SC was able to assess dietary quality of Chinese school-age children, was sensitive to demographics, and more comprehensive and accurate than the CHEI. [ABSTRACT FROM AUTHOR]
