Its academic significance has long attracted more scholars and linguists. This paper intends to explore markedness from both formal and semantic perspectives: formal markedness, distributional markedness, and semantic markedness. These three types of markedness are accounted for in detail from their definitions to their characteristics. Then the relationship of these three types of markedness is explicated. The ultimate aim of this paper is to give an insight to markedness phenomenon not only from linguistic form or structure, but from its semantic distinctions and pragmatic use. The study also aims to help foster the greater application of Markedness Theory to other linguistic fields' study展开更多

Unmarked item, compared with marked item,is more natural, more neutral, more fundamental, and has higher using frequency and wider distribution. From the perspective of markedness theory, the study, collecting 86 English passives and 85 Chinese passives(including 35 notional passives and 50 Beisentences), contrastively analyzes the unmarkedness of English and Chinese passives from the aspects of patient animacy, emotional color, and tense through example-illustration and description. The analysis shows that the unmarkedness of English and Chinese passives has different expressions in the three aspects. Inanimate patient has stronger unmarkedness in both English and Chinese passives, for it is more frequently-used than animate patient. According to people's cognition and language using habits, the emotional color of English passives and Chinese notional passives is neutral in most cases, so the neutral emotional color is unmarked.But in Chinese Bei-sentences, negative emotional color has stronger unmarkedness. As for the tense expression, English passives have wider distributions in time span and simpler structure than Chinese passives. Thus, English passives possess stronger unmarkedness in the light of tense. According to the analysis, the study proposes feasible advice for second language acquisition and translation.展开更多

The translation of tourist materials thus weighs a lot in the economic development and cross-cultural communication. But the condition is not satisfactory, there are still existing some problems in the translation of tourist publicity materials. Therefor the readers can't receive the equal information that the original text expressed. Based on this fact,the paper attempts to analyze what pragmatic failures there are in the translation of tourist materials and to analyze how the Pragmaticmarkedness Equivalence Principle(PMEP) approach can be applied to the translation of tourist publicity materials to achieve the translation equivalence.展开更多

Few researches have combined the Markedness Theory with literature theories and even no research has been done to study the Feminism Theory from the perspective of the Markedness Theory. This paper discusses markedness theory with regard to two basic issues: Why it is ok to say"历史"in Chinese, but the equivalent in English is"history", not"*herstory". Why the meaning of"governor"and"governess"is distinctively different? No research concerning the issues from the perspective of markedness has been conducted yet. This paper gives a brief review of the studies concerning the Markedness Theory, on the basis of which the question is aroused.展开更多

However, there are only few experimental studies on it and no consensus has been achieved. When it comes to Mainland Chinese foreign language learners, hardly any relevant research on such a phenomenon has been conducted so far. This paper has analyzed a sample of materials out of Chinese Learner English Corpus, and used sentence-completion and sentence-joining tests to investigate 37 college students' behavior on four types of relative clauses, in order to explore the relationship between their avoidance and typological markedness.展开更多

This study aims to evaluate the clinical effectiveness and safety of suction tubes with markings in mechanically ventilated pediatric patients. Materials and Methods: A randomized assignment was carried out on a cohort of 52 pediatric patients who underwent mechanical ventilation in the Pediatric Intensive Care Unit at the Third Affiliated Hospital of Sun Yat-sen University, covering the period from January 2022 to December 2022. These patients were divided into two groups: an improved group (n = 26) utilizing marked suction tubes, and a regular group (n = 26) employing conventional suction tubes. The objective of our study was to evaluate the clinical effectiveness of marked suction tubes. Results: The effects of the improved group on the vital signs of children undergoing mechanical ventilation were small and statistically significant compared with the regular group (p < 0.05). Additionally, the improved group exhibited a reduced frequency of sputum suction, shorter mechanical ventilation duration, and fewer days of hospitalization in the PICU compared to the regular group during the ventilation period. Notably, the difference in the duration of PICU hospitalization was statistically significant (p < 0.05). Moreover, the incidence of adverse reactions in the improved group was notably lower, with statistically significant differences observed in airway mucous membrane damage and irritating cough when compared to the regular group (p < 0.05). Conclusion: The utilization of marked suction tubes provides clinical nurses with clear guidance for performing suctioning with ease, efficiency and safety. Consequently, advocating for the widespread implementation of marked suction tubes in clinical practice is a commendable pursuit.展开更多

A data base is constructed and designed to exam the writing of the English majors in vocational college and a special attention is paid to the pseudo passive produced in the writing. Results show that due to the fact that Chinese is a topic-prominent language while English is a subjectprominent, the learners tend to transfer the subjectless structures to English production, which is reflected in the interlanguage grammar. What is more, the English passive requires more markers while the Chinese one less, which indicates that English passive is more marked than the Chinese counterpart. As a result, it is more difficult for the L1 Chinese learners to produce a wellformed English passive. In this regard, the roles of the differences between native language and target language and language transfer both play an important role in developing the interlanguage syntactic system. Based on such results, teachers should pay special attention to the teaching of English passive.展开更多

Mark theory was first proposed by the Prague School in 1930s, which is an important principle of language analysis system. The function and meaning of markup languages are mainly pragmatic, which have procedural meaning and no conceptual meaning. Markedness phenomenon is not only the inherent characteristics of language symbols, but also the product of social life and different cultures. Due to the great difference between cultural background and social environment of Chinese and English speaker, thus there are many similarities and differences in the language, society and culture mark. The mark phenomena of English nouns are mainly related to the category of nouns and the opposite nouns. However, Chinese nouns have no strict morphological changes. In this paper, we discuss the theory of mark phenomenon and analyze a contrastive study on mark phenomena of English and Chinese Languages.展开更多

Experimentally it was found for the first time that when the intensive sediment motion occurs downstream over a gentle slope, the siltation of the riverbed is induced and the sediment particles can move upstream rapidly in the form of a retrograde sand wave, resulting in a higher water level along the river. To further study the complex mechanisms of this problem, a sediment mass model in the framework of the Smoothed Particle Hydrodynamics(SPH) method was presented to simulate the riverbed evolution, sediment particle motion, and the generation and development of dynamic hydraulic jump under the condition of sufficient sediment supply over a steep slope with varying angles. Because the sediment is not a continuous medium, the marker particle tracking approach was proposed to represent a piece of sediment with a marked sediment particle. The twophase SPH model realizes the interaction between the sediment and fluid by moving the bed boundary particles up and down, so it can reasonably treat the fluid-sediment interfaces with high CPU efficiency. The critical triggering condition of sediment motion, the propagation of the hydraulic jump and the initial siltation position were all systematically studied. The experimental and numerical results revealed the extra disastrous sediment effect in a mountainous flood. The findings will be useful references to the disaster prevention and mitigation in mountainous rivers.展开更多
