The Change of Perspectives on Aging Research： From Static to Dynamic

Rapid aging process will have a profound impact on China＇s social economy, and the traditional static aging research framework has been unable to adapt to the rapid aging of the opportunities and challenges. The aging perspective needs to be extended from tradition to modem, from static to dynamic. In this paper, from the static aging, the core of the research on dynamic aging is the linkage between internal and external changes of aging, and analyzes the necessity, possibility, change and transition path from static aging to dynamic aging, Research on the shift of research focus in the process of research.

Accounting Research： A Synthetic View of Epistemological Differences

In this paper, a number of basic differences in the contemporary accounting research are explored： （1） American versus European research perspectives; （2） mathematically-based versus non-mathematically-based research approaches; （3） positive versus naturalistic methodologies; （4） objectivist versus subjectivist assumptions concerning the accounting craft; and （5） functionalist versus interpretive paradigms on the accounting theory. In this paper, the accounting literature is discerned from its methodological characteristics combined with some basic metaphors of accounting （e.g., accounting as the economic goods, the political output, the social process, or the cultural product）. Facing these differences, a synthetic view is called for to recognize the unique strengths of different perspectives. It is believed that different perspectives can enrich themselves by learning from each other. The synthetic view can then enhance the overall quality of the accounting research. Facing the wide-ranging needs of the contemporary accounting research, the important strategy is to match research methods/perspectives with research questions/purposes.

Review of urban ecosystem services from 2010 to 2020:An analysis based on CiteSpace

This paper systematically combs 416 literature on urban ecosystem services (UES) in China and other countries from 2010 to 2020,and carefully interprets the abstracts of 383 effective literature.According to the classification method of the research perspectives of ecosystem services proposed by Luederitz C,the literature is divided into six categories:ecology,governance,methods / tools / guidelines,social networking,economy and planning,and Excel and CiteSpace software were used for data statistical analysis and visual processing.The research shows that:in terms of research perspectives,foreign researches are evenly distributed in six categories:ecology,governance,methods / tools / guidelines,social networking,economy and planning,while domestic research perspectives are relatively concentrated in three categories:economy,governance,methods / tools / guidelines,and the proportion of economic category is particularly significant.In terms of research contents,there are more studies on climate governance,decision-making mechanism and method innovation abroad,while there are more studies on the measurement of carbon sequestration and oxygen releasing,the evaluation of ecological security pattern and the quantitative evaluation of UES’s economic value in China,and there are less studies on institutional organization structure and policy tools,innovative methods of UES’s value evaluation,the potential role of UES on some social phenomena,the relationship between UES and residents’ behavior and perception.

German Popular Music Studies as Part of （International） Media Cultural Studies

This paper begins by explaining current developments in popular music research, mainly in connection with approaches used in international media and Cultural Studies. It then provides an overview of German-language research methods and discourses on popular music. In addition to the traditional reflections from musicology and music education, nine perspectives will be described, primarily from the media, communications, culture and social sciences. These nine contemporary perspectives are distributed along lines of thematic focus, moving beyond disciplines or fields per se. This paper will close with a list of suggestions for popular music research and education in the German cultural sphere, insisting above all on a clear connection/link, in the sense of a mixing/incorporation/integration, with （current） international discourses. Finally, the paper synthesizes German research, not only to systematize it but also to illustrate its diversity and multiperspectivity.

Appraisal of the Production-Oriented Approach： An Introduction

The production-oriented approach （POA） has been developed over a decade. It is driven by the need to improve English classroom instruction for university students in China （Wen, 2016）. It is also motivated by the aspiration to enhance the quality of foreign language education in other similar pedagogical contexts outside China. A volume of research has been done by Wen Qiufang and her research team, to formulate the theory of POA and to test its effectiveness in classroom pedagogy （e.g. Wen, 2016, 2015; Yang, 2015; Zhang, 2015）. At the moment, the POA is still at an early stage of theory building and almost all empirical research is done in the Chinese context. In order to improve the quality of this theory and to make it intelligible to the international academic community, a one-day symposium was held in Beijing Foreign Studies University on May 15, 2017. The symposium was entitled ＇The first international forum on innovative foreign language education in China： Appraisal of the POA＇. In the forum, leading experts in applied linguistics were invited to discuss the strengths and weaknesses of the POA and the directions for its future development. The symposium was the first attempt for the POA research team to discuss its latest work with international scholars. This Viewpoint section collects the responses of four experts who participated in the symposium, listed in alphabetical order. The collection of articles covers three topics related to the POA： its pedagogical application, its use for teacher training, and its research. Alister Cumming is Professor Emeritus and the former Head of the Centre for Educational Research on Languages and Literacies, University of Toronto, Canada. His article focuses primarily on POA research as an exemplary case of design-based research. Rod Ellis is Research Professor in the School of Education at Curtin University, Australia. He discusses POA in terms of pedagogy, teacher training and research, with both critiques and constructive suggestions. Paul Kei Matsuda is Professor of English and Director of Second Language Writing at Arizona State University, the writed states. He responds to POA from the perspective of an expert researcher and teacher of L2 writing. Charlene Polio is Professor and Associate Chair in the Department of Linguistics ＆ Germanic, Slavic, Asian ＆ African Languages atMichigan State University, the writed states. She conceptualises POA as a useful method to address some issues in pre-service teacher development. Overall, the articles in this section are insightful and reader-friendly. They are not only useful for the development of POA in particular, but may also be valuable to a broad range of researchers as they touch upon pertaining issues, as well as emerging topics, in the field of applied linguistics. We therefore find it necessary to make them accessible to a wide readership.
