The first issue is when management accounting system was formed; the second is how to evaluate its development in subsequent decades; the third is how to evaluate the development of practice and research of management accounting in almost twenty years after Relevance Lost was published. The role of Relevance Lost in practice and theoretical research of management accounting is widely recognized, and the disagreement with it in this paper is in the specific area of the development history of management accounting. The authors of this paper believe that the development, through having its ups and downs over time, is generally speaking a continuous process, not separated by disconnected phases, leaping from one to another. Along with the progress in practice and research, researchers and practitioners are deepening their understanding about the theoretical foundation and practical development of management accounting. The history of development of management accounting is consistent with the process people gradually understand it.展开更多

He was an influential living Buddha (Renpoche) in Tibetan Buddhism and a talented and legendary historical figure. Nowadays, more and more scholars, poets and translators have devoted to the study of his works. Here we will focus on discussing the English translation of his poems and their value. We analyze texts of the Tsangyang Gyatso's Poems (Chinese-English) and seek to further study the translation principles such as "retaining truth, seeking goodness and preserving beauty". By doing this, we strive to improve the quality of translation, give consideration to the construction of the four elements such as poetic meaning, emotion, tone and intention, to enable the reader to achieve the senses and the acquisition of images, to provide more perfect translation in the "Tsangyang Gyatso Vogue", to promote the dissemination and sharing of Tibetan culture and to inject new vitality.展开更多

This was accomplished by analyzing surviving historical documents, including budgetary notes and a diary. The Kabu-ido system was a customary institution for groundwater management in a ring levee area of the Noubi Plain in Japan that consisted of three programs: restriction of groundwater pumping through a permit system, groundwater pricing and economic compensation. The system was created in the 1810s and survived for 100 years. This paper covers the Kabu-ido system from the 1810s to the 1860s, the first half of the 100-year history. Excessive groundwater pumping is not a new environmental problem. Although many case studies have investigated remedial actions, few have investigated how local residents addressed the problem before the 20th century because of a lack of documents. The Kabu-ido system is an exception in which of the procedure was documented in writing. The historical data indicate that it was a pioneering institution for groundwater management.展开更多

Changes in their area were derived from two Chinese glacier inventories; one from the 197o 1:5o,ooo scale Chinese Topographic Maps series and the other from Landsat TM/ETM+ images acquired in 2009. Analyses also included boundaries from 2000 and 2014 Landsat TM/ETM+ images. A continuing and accelerating shrinkage of glaciers occurred here from 1970 to 2014, with glacier area decreasing by 244.38±29.48 km^2 (27.4%±3.3%) or 0.62%±0.08% a^-1. While this is consistent with a changing climate, local topographic parameters, such as altitude, slope, aspect and debris cover, are also important influences. Recession is manifested by a rise in the elevation of the glacier terminus. The shrinkage of glaciers with NE, N and NW orientations exceeded that of other aspects, and glaciers with SE and S orientations experienced less shrinkage. Changes in the average positive difference of glaciation (PDG) show that the western Nyainqentanglha Range has unfavorable conditions for glacier maintenance which is being exacerbated by a warming climate since 1970.展开更多

Tree establishment at treelines requires favorable climate, suitable microsites, and viable seeds. But most researches have been addressed treeline microclimate and its effects on tree regeneration, the knowledge of seed quantity and quality and its controls on seedling recruitment were limited. We measured seed rain, soil seed bank, seed germination rate and seedling recruitment in natural forests in combination with seed transplanting manipulation to evaluate the controls of seed quantity and quality on seedling recruitment of Abies georgei var. smithii (smith fir) along altitudinal gradient, with focus on treeline ecotone in the Sygera Mountains, southeastern Tibetan Plateau. Both seed quantity and seed quality of smith fir decreased with increasing altitude and was thereby associated with decline in seed germination rate. Seed quantity and seedling recruitment were better in north-facing slope than in south slope. The treeline ecotone above 42oo m appeared as the threshold altitude to sharply decrease seed quality and seedling recruitment. The emergence and overwintering rates of transplanting seeds from 3600-38oo m also went down remarkably above 4200 m at north-facing slope. It also underpins the fact that treeline ecotone is the bottleneck of seedling recruitment. Our results suggest that seed quantity and quality are the principal limitation of treeline upward advance. This study also provides evidence to support stable treeline position in southeastern Tibetan Plateau.展开更多

In order to understand this condition more deeply, I develop the notion of "reason of opinion" to characterize the process as "prospective consensus building." This prospective consensus building should satisfy the requirements of having "history of reason" and "list of risks." The former requirement, history of reason, can be characterized by making clear when one started to form the reason of an opinion, how one formed the reason, what kind of relationship is supposed to be between the present opinion and its reason, and what kind of result is expected to come out after a decision making. The latter requirement, the list of risks, should display what kind of outcomes are supposed to come out in each alternative of the decision making. Prospective consensus building makes it possible, firstly, for the stakeholders to understand the patient's needs more deeply. For the patient, secondly, the each stakeholder would be able to become aware of his/her own sense of value and to confirm what he/she expects from the result of his/her decision-making. For all the stakeholders, thirdly, it would make it possible to decrease the amount of risks of misunderstanding and to share their expectations for their well-being. Finally, the stakeholders can reach a satisfactory consensus and find a way to the better solution.展开更多

W. Smith (AGS), the crystal structure was measured with a Bruker APEX-Ⅱ area-detector diffractometer instrument and the technology of extracting in combination hydrolysis in situ (ECHS) was compared with these of traditional methods. The crystal belongs to the monoclinic system, space group P2b with unit cell parameters: a=(8.3652±0.0006) nm, b=(24.721±0.002) nm, and c=(14.5587±0.0011) nm, α=90°, β=97.850 (4) °, γ=90 °, V=2982.51 nm3, Dc= 1.179 mg/m3, and the molecular number (Z) of elementary structures was 2. The comparisons show that the extraction rate of acankoreanogenin with ECHS methods is much higher than that of traditional methods. Then, central composite design-response surface methodology (CCD-RSM) was adopted for optimizing the extraction rate of ECHS methods. The optimized values of extraction parameters are as follows: for the for extraction process of acid hydrolysis are that extraction time 110.8 min, solvent-herb ratio 11.5 and acid content 5.25%; the best extraction process of basic hydrolysis are that extract time 120 min, solvent-herb ratio 8.7 and the alkali content 8.79%. Finally, the extracts were purified with decolorizing carbon after alkali solution and acid-isolation and purity of acankoreanogenin was 98.7%.展开更多

Chinese music covers a wide range, which includes China traditional opera, minority drama, local and regional opera, and the song and dance drama and music with the sense of the times.However, in the music history research and teaching in our country currently, because the current art education of the old system and the traditional mechanical reasons, study on the history of music lacks of effective view in the breadth and depth.Because of these reasons, there is a lack of the object of study and research methods, so in the course of study on the China music history, it has some deficiency and embarrassing phenomenon.In this paper, it takes the analysis on deletion and embarrassing situations in our country at present on the history of music, and finds out the corresponding solutions for it.展开更多

Thanks to musical analysis we are able to trace the compos technique, or assess the artistic value of given work. In addition to traditional, descriptive methods of e it ody, onal music analysis, we can observe in 20th century the development of methods based on science (mathematics, otherwise statistics). Such methodologies allow us to obtain a strict understanding of the structure of musical pieces Applying mathematical methods for musical analysis seems very reasonable in relation to the output of Frederic Chopin, due to large originality of the elements of musical pieces of this composer. Present paper was written as a result of research related to the applying of numerical method of analysis for exploring the tonal structure of Chopin's works. The author's research method enables a strict analysis of the chord's domination that can be classified under given key (range)--taking into consideration the harmonic functions. By the method of analysis we can get charts that depict whole diatonic vertical music material of the given piece. The main objective of the present study is to describe observations on the high uniqueness in the tonal construction of selected Chopin's mazurkas, especially, when compared to the miniatures of other composers of the first half of the 19th century and previously analyzed Chopin's pieces: etudes, preludes, and songs.展开更多

Both own a very long history and maintain an interdependent relationship with each other. The dances accompanied by music in China' s primitive tribes and the lyric poetry in the ancient Greek times can be said to be the coexistence form of music and literature. Although music and literature have undergone a whole development process from a unified development to an independent development, there are links always maintained between the two art forms. In this paper, the coexistence and fusion between music and literature are specifically introduced from different aspects.展开更多

Current limitations to the law are mainly due to the accepted patriarchal view on law as a form of objective and rational knowledge, outside which there are only impracticable and irrational views. I investigate the case of marriage jurisprudence in the UK, as a prominent example, because it has long accepted marital rape as objectively and rationally part of a wife's duty. Even though changes have occurred which improve the marital rape jurisdiction and prejudicial disbelief concerning a woman's private life is still used in the courts to question the credibility of the victim. Over the past year, extensive efforts have been made to reform the management of rape cases. Whilst there is a need to acknowledge the seriousness of the accusation with rigorous legal principles which provide appropriate safeguards for the accused person as well as the complainant, especially bearing in mind the often "private" circumstances, with a concomitant lack of witnesses, it remains the case that the rate of attribution in attempts to secure successful prosecutions in rape case remains overwhelming. I show how a Wittgensteinian approach to law would take into consideration the shape ofgendered lives as they are experienced, and hence would not accept just one legal interpretation of marital law. The phenomenon of"seeing-as" in Wittgenstein's philosophy can support the experience of being jolted into appreciating the feminist aspect of consent in marital sexual relationships.展开更多

METHODS: We studied a total of 2242 patients diagnosed with HCC between January 1990 and July 2008, whose family history of primary liver cancer was clearly described in the medical records.positive family history of HCC and 2077 (92.6%) did not. The male to female ratio was 3.6:1, and the major causes of HCC were chronic hepatitis B virus (HBV) infection in 75.1%, chronic hepatitis C virus infection in 13.2% and alcohol in 3.1%. The median ages at diag- nosis in the positiveand negative-history groups were 52 years (range: 29-79 years) and 57 years (range: 18-89 years), respectively (P < 0.0001). Furthermore, among 1713 HCC patients with HBV infection, the number of patients under 45 years of age out of 136 patients with positive family history was 26 (19.1%), whereas those out of 1577 patients with negative family history was 197 (12.5%), suggesting that a positive family history may be associated with earlier development of HCC in the Korean population (P = 0.0028). CONCLUSION: More intensive surveillance maybe recommended to those with a positive family history of HCC for earlier diagnosis and proper management especially when HBV infection is present.展开更多

The phenomenon of"seeing-as" in Wittgenstein's philosophy can support the experience of being jolted into appreciating the feminist aspect of consent in marital sexual relationships.

文摘AIM: To evaluate the relationship between a positive family history of primary liver cancer and hepatocellular carcinoma (HCC) development in Korean HCC patients. METHODS: We studied a total of 2242 patients diagnosed with HCC between January 1990 and July 2008, whose family history of primary liver cancer was clearly described in the medical records.positive family history of HCC and 2077 (92.6%) did not. The male to female ratio was 3.6:1, and the major causes of HCC were chronic hepatitis B virus (HBV) infection in 75.1%, chronic hepatitis C virus infection in 13.2% and alcohol in 3.1%. The median ages at diag- nosis in the positiveand negative-history groups were 52 years (range: 29-79 years) and 57 years (range: 18-89 years), respectively (P < 0.0001). Furthermore, among 1713 HCC patients with HBV infection, the number of patients under 45 years of age out of 136 patients with positive family history was 26 (19.1%), whereas those out of 1577 patients with negative family history was 197 (12.5%), suggesting that a positive family history may be associated with earlier development of HCC in the Korean population (P = 0.0028). CONCLUSION: More intensive surveillance maybe recommended to those with a positive family history of HCC for earlier diagnosis and proper management especially when HBV infection is present.
