Based on the subsystem-attitude system in Appraisal Theory, an attempt is made to conduct a comparative analysis of attitudinal resources in English and Chinese news on MH370 accident. Meanwhile, certain attitudes or stances conveyed by the authors of these news will be revealed through some typical examples. Both quantitative and qualitative methods are adopted in the present study to make a statistical and interpretive analysis of the collected materials. It is found that both English and Chinese news contain many attitudinal resources. There are similarities and differences concerning the distribution of attitudinal resources between English and Chinese news. The findings suggest that though news is expected to be objective and factual, it may imply the authors＇ subjective attitudes to some extent. So readers should get hang of the different opinions and stances hidden behind different news reporting so as to improve abilities to appreciate and differentiate different news.展开更多

The evaluation in this Appraisal System can be further classified into explicit evaluation, which inscribes the attitude through the attitudinal vocabulary and implicit evaluation, which invokes the attitude through the use of non-core lexis. Martin （2005） pointed out that the implicit evaluation is realized by three approaches： lexical metaphor, the selection of ideational meanings, and graduation. However, the invoked attitude can be achieved by an amount of resources other than the above approaches. In this paper through the exploration of invoked attitude in the English-language China Doily, we find that the attitude is also invoked through grammatical metaphor, general noun as well as conjunction. It is of great significance to decode the journalists＇ or newspapers＇ viewpoints by exploring the implicit evaluation in the news text.展开更多

The aim of the paper is to make a systematic literature review, to map open innovation studies, and to re-conceptualize the openness according to two dimensions： degree of technology convergence and ontology of openness. In particular, we propose a classification of open innovation, based on the distinction between the originator/developer of the knowledge and the user. Users are a ubiquitous category, because they can be originators, as well as customers of the innovation itself. Therefore, we point out that there are three types of open innovation, whose degree of openness is defined according to an ontological dimension： at users’ level, at an industry level, and among different fields or industries. Firm’s structure affects the propensity to open innovation adoption; and the type of innovation itself. Finally, we identify another literature gap： the relationship between the open innovation model and grand challenge. Even if open innovation seems to be ideally connected to grand challenges and many industries actually adopt this model, there seems to emerge a gap in literature. Therefore, we propose a conceptual model for future researches.展开更多

Auxin(indole-3-acetic acid) is an important plant growth regulator and is synthesized within plant tissues through L-tryptophan(L-TRP)-dependent and-independent pathways. It has been found that plants respond to exogenously applied L-TRP due to insufficient endogenous auxin biosynthesis. The exogenous application of L-TRP is highly significant for normal plant growth and development.L-tryptophan is applied through foliar spray, seed priming, and soil application. Soil-applied L-TRP is either directly taken up by plants or metabolized to auxin by soil microbiota and then absorbed by plant roots. Similarly, foliar spray and seed priming with L-TRP stimulates auxin synthesis within plants and improves the growth and productivity of agricultural crops. Furthermore, L-TRP contains approximately 14% nitrogen(N) in its composition, which is released upon its metabolism within a plant or in the rhizosphere and plays a role in enhancing crop productivity. This review deals with assessing crop responses under the exogenous application of L-TRP in normal and stressed environments, mode of action of L-TRP, advantages of using L-TRP over other auxin precursors, and role of the simultaneous use of L-TRP and auxin-producing microbes in improving the productivity of agricultural crops. To the best of our knowledge, this is the first review reporting the importance of the use of L-TRP in agriculture.展开更多
