These reasons are likely to lead to a more respected attitude of Vietnamese people toward “super-ordinates”, and a more polite and concessive attitude toward “subordinates” This attitude is witnessed frequently in Vietnamese economic corpus Vietnamese writers use many types of modalities as hedging devices (especially modal verbs) to mitigate their statements In our corpus, Vietnamese writers use more modal verbs than English writers (0.813 devices per 100 words in Vietnamese corpus compared to 0.485 devices per 100 words in English corpus) 197 (4) Cho nên, doanh nghiệp Việt nam nên tăng cường sử dụng biện pháp nhường quyền thương mại, sử dụng biện pháp nhượng quyền thương mại (VE 5) (Therefore, Vietnamese enterprises should strengthen the give-up method in trading right, and use the selling method in trading right) 198 (6) Chúng [tỷ giá giao ngay] khác hoàn toàn với chế tỷ giá “bám theo thị trường” dường thực thời gian qua (VE 12) (They [spot delivery exchange rate] are totally different from exchange rate mechanism “belong to market” as we have probably realized so far) Nên and dường in the examples above were two weak forms of obligation modal If the writers in the two examples above substituted these two modal verbs with other modal verbs (e.g phải (must); cần (need)) or omit them, the statements would become too authoritative which would likely to pose potential threat to the readers’ negative face because in these cases, subjects were clear doanh nghiệp Việt nam and These devices helped the writers show their respect to their interlocutors Two types of hedging devices having the most significant difference between the two languages are Nouns/Pronouns and Compound hedges The p-level of these hedging types are very small (P = 0.000) which is much smaller than α level (0.05) With the low P-value and high degree of F-value (26.69 for nouns/pronouns and 127.90 for compound hedges), we can reject our nullhypothesis that the mean of these types of hedges are almost the same, and our alternative hypotheses are accepted Moreover, the average levels of hedges between English and Vietnamese are also quite different On the average, there are more than compound hedges used in English texts per 100 words, while this number in Vietnamese texts is nearly hedge only The average number of Nouns/Pronouns used as hedges in English is 0.8168 hedges per 100 words, while in Vietnamese is 0.2648 (see Table 5.9 and Table 5.10 for more information.)

In example (199), non-subject structures hiểu…; có khả năng… integrated with unidentified phrase hay bất cú lúc (or at any time) assisted the writer to reduce the authority which may appear without assistance of these devices Similarly, the impersonal structure nên áp dụng…(should apply) in example (200) reduced authority of the statement because the impose obligation in the writer’s suggestion was merely a proposal, thereby tentative and left room for the writer’s audience to make their decision to follow the suggestion or not Furthermore, as mentioned above, cần, cần phải are hedges containing power inside them; therefore, Vietnamese writers often try to avoid affecting the audiences’ negative face by using non-subject structures in order not to mention to any particular person realizing actions in the statements To sum up, the investigation of more than 55,000 words corpus reveals that there is a significant difference about hedging usages between English and Vietnamese writers When analyzing the two corpuses, English and Vietnamese, we also find that not all English hedging devices can be applied to Vietnamese corpus Moreover, not only different in quantity of hedges, sometimes the purposes of using hedging devices are also different in two languages We can find the differences in the two following examples 201 (3) Do vậy, để giải vấn đề này, nên kết hợp sử dụng hạn ngạch xuất thuế xuất gạo (VE.11) (Therefore, in order to solve this problem, we should integrate using export quota into using export tax on rice.) 202 (9) We conclude by suggesting an additional propagation mechanism, vertical specialization (10a) We mean the phenomenon (10b) by which countries increasingly specialize in producing only particular stages of a good's production sequence (10c) so that a good crosses multiple borders while in process (EE 2) We was used in both examples (197) and (198) above; however, its purposes were different in the two examples In Vietnamese example, we combined with should assisted the writer to diminish the power of the suggestion The writer in this example indicated that he/she also had certain responsibility in that situation and naturally got the audience involved into what he/she was going to Meanwhile, in English example, we was used with an aim to assert the writer’s ego The writer in example (198) emphasized that what the writer and his/her colleagues (plural pronoun we) were going to conclude was the contribution of the writer to economic field In other word, by using we, the writer wanted his positive face was recognized by professional circle 184 (LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)

Besides using single hedges to achieve purposes in emphasizing, or downtoning the statements, economic writers also interlaced some linguistic devices to reenforce their statements In this point, English writers also use more devices at the same time than Vietnamese writers 185 (LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)

Chapter Concluding Remarks and Implications This chapter will summarize what the study has covered and examine some implications especially pedagogical implications from the study Firstly, I will recap principal findings of the study, condense some main contributions of the study to the understanding of features in RAs in general and of hedging phenomenon in particular Then, I will consider the implication of the research for studying hedging usage and for teaching ESP Finally, I also mention to some remaining questions, as well as suggest some directions for further study 6.1 Concluding Remarks This is a corpus-based study of 55, 000 words of English and Vietnamese The study is the combination of both systematic classification of linguistic forms and pragmatic explanations of hedging devices In Vietnam, while other previous researchers only focused on a particular linguistic aspect of hedging usage, or a certain politeness phenomenon in spoken language, this study can be considered the first comprehensive study of hedging devices in written discourse The study summarizes some outstanding forms of English and Vietnamese hedging devices, important functions of hedges and some explanations about the differences between the two languages Besides providing a linguistic system of hedging devices, the study also provides pragmatics analysis which cannot be achieved through intuitive observations by dealing with hedges in certain contexts where accurate purposes of hedging users are expressed By doing this way, the study also implies that in order to fully understand a hedge, it is necessary to analyze that device in its social context The following points are some main findings of the research Hedging is a typical, indispensable, and massive communication device in economic RAs with different functions (Chapter III and IV) On the average, there is more than one hedge in every 100 words in English corpus, and nearly 0.5 hedges per 100 words in Vietnamese corpus This number is much higher when specific devices are analyzed This finding suggests that more theories of language should consider hedging devices seriously Hedging devices can be used to realize writers’ academic 186 (LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)

The English corpus and the Vietnamese corpus have many differences in frequent occurrence of each type of hedges, as well as in the quality of the writing (chapter V) The corpus analysis of this thesis indicates a restricted use of modal verbs in English corpus, but a different result is seen in Vietnamese corpus where modal verbs outweigh other types of hedging Nouns or Pronouns functioning as hedges are mostly used in the English corpus, but not frequently used in Vietnamese corpus Another significant difference between the English and Vietnamese discourses in term of hedging usage is the prominence of using more than one hedge at the same time English writers use six times this type of hedges more than Vietnamese writers (6.512 compared with 0.516 devices per 100 words) The harmony of many hedges in the same sentence increases the effect of this shielding device in English corpus Pragmatically, hedging is a versatile resource that writers intentionally use to increase interpersonal meanings (chapter III and IV) Hedging is a good way to design our opinions to maximize the expression of interpersonal emotions as well as to address the need for deference and cooperation when trying to gain agreement during negotiation Hedging not only allows writers to express whether they believe that something is true, but to show how they feel about it, and to allow the writers manage conversation for maximal interpersonal efficiency The relationship between writers and readers is increased when the writers use hedges to avoid loosing their and their audience’s politeness faces Hedges assist the writers to shield them from negative reactions from opposite ideas; therefore, they can increase ratification of claims from the audience Besides that, the writers can also encourage their readers to get involve into the decision making process by giving the audience chances to choose either following the writers’ suggestions or not By doing this way, the writers want to acknowledge the readers’ contribution into the social process of knowledge accreditation Hedging devices should be considered in a certain context (chapter III, IV) The study emphasizes the relationship between a discourse community, standards of knowledge and textual representations with the use of hedges The semantic analysis of hedging usage achieved through corpus analysis in this research may not be fully understood without combination of pragmatic constraints in determining meanings Therefore, the study 188 (LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)

The study results also contribute to the comparison between native and non-native learners for educators The framework created in the study provides basic language modal for educators to examine learner’s pragmatic comprehension of hedges in English and Vietnamese The study results also infer a suggested modal to teach non-native speakers the same context sensitivity and conventionality as native speakers in this field of use While hedges have a variety of observed uses in RAs, this does not automatically mean that similar cases of hedging might be applied in all types of RAs In other words, researchers should take into account the multifunctional nature of hedging phenomena and the possibility that hedges may differ from others in various types of RAs However, besides a wide range of conscious activities teachers design to help students understand hedges, students should practice their writing to raise their natural awareness of hedges, and see the importance of hedging in a large context They should be practiced to understand hedges as both text-based items and discourse-based strategies In teaching process, both reading and writing have to be linked in a complete text where sufficient contexts are provided to show the authors’ assumptions when using a hedge 6.3 Suggested for further study Information concerning the rhetorical features of RAs may be essential for those accommodating scientific information for public wider than the immediate scholarly community Variability of rhetorical situations and the consultant effects on different linguistic phenomena would in all likehood merit further attention in further work A further study which should be made for another function of hedges is to express rhetorical meanings Hedging device might be a signal for audience to predict the changes of the writers’ propositional content Another empirical question such as the relationship between hedging and cohesive elements of rhetorical structures, say parallelism is a topic for further study The study may also take into account of disciplinary variation by investigating effects of genders on hedging expressions Studying hedging devices in other different genres (applied linguistics, physics, and sociology) will probably another suggestion for further study 194 (LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)(LUAN.van.THAC.si).hedging.devices.in.english.and.vietnamese.economic.research.articles.(ERAs.)
