Based on intertextuality point of view, researching and studying Dickinson's background, education, her family, as well as the society where she lived. Analyzing the Dickinson's poets and other writers' or poets' works in different contexts of classical inheritance, and philosophical thought. To break up the text of the solitary, put the text in the associative network of readers' experience, take the text as the link of the writer and the readers, and connect the inheritance, experience of the writer and the readers' reading. Use the method of intertextuality to interpret the non-meaning of the text, then to understand the significance of existence of Dickinson's works. This thesis mainly studies from the following aspects: It reveals the intertextuality of the works of Dickinson and Shakespeare, Isaac Watts and some Romantic poets from the point of classical context. By studying from the point of Transcendentalism and Existentialism, It explores the intertexutality relationship between Dickinson and Emerson, Thoreau as well as other writers. It also disserts the significance and influences of Dickinson's works through comparing and analyzing the intertextuality between Dickinson and Li Qingzhao, Xi Murong, as well as Annebaby. 展开更多

After Wang Yangming experienced the revelation of Confucian philosophy at Longchang,he disseminated his heart-mind doctrine by engaging in teaching.A great number of scholars in Guizhou followed him and formed the Qian sub-school of the heartmind philosophy,the earliest of local Yangming sub-schools in the country.roughout the Zhengde and Wanli periods of the Ming dynasty,Yangming scholars and local ocials in favor of the heart-mind philosophy worked in collaboration to collate and print six books of Wang’s works in Guizhou.Among these,A New Supplementary Edition of Master Wang Yangming’s Writings represents the most fruitful e ort by both government ocials(Wang Xing)and local scholars(Chen Wenxue and Ye Wu).As an o print block-carving edition of Wang Yangming’s collections in the early years,it is extremely treasured for its rarity of edition and historical value.e profusion of printing of Wang’s works in Guizhou re ects the wide circulation of his heart-mind doctrines in China’s southwest frontier regions,vividly mirroring the growth of Wang’s philosophy outside cultural centers as well as the complicated history of interactive in uence between Chinese marginal and central cultures. 展开更多

The Relevance Theory put forward by Sperber and Wilson not only gives rise to a new research on pragmatics, but also provides a new theoretic foundation for other disciplines. Gutt applies the theory to translation and gives a relevance-theoretic account of translation. The relevance-theoretic communicative model provides rational explanation for existence of the implicit information. The appropri ate treatment of the implicit information is consistent with readers' cognitive environment and expectation. Human communication de pends on not only the text, but also the inferential context. The adequate contextual effect is derived from the correct judgment and infer ence of the implicit information in communication. Therefore, the translator should match the original author' s intention with target text readers' expectation to make sure that they yield adequate contextual effects with appropriate processing efforts. Implicitness is one of the features of Shakespeare' s works. It is more demanding for the translators to catch and transfer to the target readers the implicit information. Zhu Shenghao and Liang Shiqiu, the two famous translators adopt different translation strategies to deal with the implicit information in the works. 展开更多

AIM To determine the prevalence of work disability in inflammatory bowel disease(IBD), and to assess risk factors associated with work disability.METHODS For this retrospective cohort study, we retrieved clinical data from the Dutch IBD Biobank on July 2014, containing electronic patient records of 3388 IBD patients treated in the eight University Medical Centers in the Netherlands. Prevalence of work disability was assessed in 2794 IBD patients and compared with the general Dutch population. Multivariate analyses were performed for work disability(sick leave, partial and full disability) and long-term full work disability(> 80% work disability for > 2 years).RESULTS Prevalence of work disability was higher in Crohn's disease(CD)(29%) and ulcerative colitis(UC)(19%) patients compared to the general Dutch population(7%). In all IBD patients, female sex, a lower education level, and extra-intestinal manifestations, were associated with work disability. In CD patients, an age > 40 years at diagnosis, disease duration > 15 years,smoking, surgical interventions, and anti-TNFα use were associated with work disability. In UC patients, an age > 55 years, and immunomodulator use were associated with work disability. In CD patients, a lower education level(OR = 1.62, 95%CI: 1.02-2.58), and in UC patients, disease complications(OR = 3.39, 95%CI: 1.09-10.58) were associated with long-term full work disability.CONCLUSION The prevalence of work disability in IBD patients is higher than in the general Dutch population. Early assessment of risk factors for work disability is necessary, as work disability is substantial among IBD patients. 展开更多

To determine the rational layout parameters of the lateral high drainage roadway(LHDR) serving for two adjacent working faces, a mechanical model of the LHDR under mining influence was established, and the overburden fissure, mining-induced stress distribution rules were analyzed. First, the development characteristics of mining-induced overburden fissure and the stress distribution law of the upper section of the working face were analyzed. Second, by analyzing the distribution law of vertical stress at different layers, the lateral distance of the LHDR was determined as 25 m. Third, by analyzing the surrounding rock deformation effect, stress distribution law, and overburden fissure distribution law of the LHDR at the heights of 20, 25, and 30 m away from the roof, the rational horizon of the LHDR was determined to be 25 m. Finally, an example of a LHDR located 25 m above the roof of the No. 2 coal seam and 25 m away from the No. 2-603 working face was presented. Results show that when the No. 2-603 coalface is being mined, the surrounding rocks lag 80 m or even further and the working face tends to be stable. The relative deformations of the roof and floor of the roadway and both of its walls were 583 and 450 mm,respectively. The reduction rate of the roadway section was 21.52%–25.32%. The section of the roadway was sufficient to extract the pressure relief gas in the overburden of the No. 2-605 working face. The average gas concentration and the pure volume at the branch pipeline were 24.8% and 22.3 m^3/min,respectively, showing that the position of high-level boreholes was reasonable. 展开更多

Energy methods and the principle of virtual work are commonly used for obtaining solutions of boundary value problems (BVPs) and initial value problems (IVPs) associated with homogeneous, isotropic and non-homogeneous, non-isotropic matter without using (or in the absence of) the mathematical models of the BVPs and the IVPs. These methods are also used for deriving mathematical models for BVPs and IVPs associated with isotropic, homogeneous as well as non-homogeneous, non-isotropic continuous matter. In energy methods when applied to IVPs, one constructs energy functional (<i>I</i>) consisting of kinetic energy, strain energy and the potential energy of loads. The first variation of this energy functional (<em>δI</em>) set to zero is a necessary condition for an extremum of <i>I</i>. In this approach one could use <i>δI</i> = 0 directly in constructing computational processes such as the finite element method or could derive Euler’s equations (differential or partial differential equations) from <i>δI</i> = 0, which is also satisfied by a solution obtained from <i>δI</i> = 0. The Euler’s equations obtained from <i>δI</i> = 0 indeed are the mathematical model associated with the energy functional <i>I</i>. In case of BVPs we follow the same approach except in this case, the energy functional <i>I</i> consists of strain energy and the potential energy of loads. In using the principle of virtual work for BVPs and the IVPs, we can also accomplish the same as described above using energy methods. In this paper we investigate consistency and validity of the mathematical models for isotropic, homogeneous and non-isotropic, non-homogeneous continuous matter for BVPs that are derived using energy functional consisting of strain energy and the potential energy of loads. Similar investigation is also presented for IVPs using energy functional consisting of kinetic energy, strain energy and the potential energy of loads. The computational approaches for BVPs and the IVPs designed using energy functional and principle of virtual work, their consistency and validity are also investigated. Classical continuum mechanics (CCM) principles <i>i.e.</i> conservation and balance laws of CCM with consistent constitutive theories and the elements of calculus of variations are employed in the investigations presented in this paper. 展开更多
