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

After 60 years of study, significant achievements have been made in terms of classification schemes, genetic mechanisms, and depositional models of deep-water gravity flows. The research history of deep-water gravity flows can be divided into five stages： incipience of turbidity current theory; formation of turbidity current theory; development of deep-water gravity flow theory; improvement and perfection of deep-water gravity flow theory; and comprehensive development of deep-water gravity flow theory. Currently, three primary classification schemes based on the sediment support mechanism, the rheology and transportation process, and the integration of sediment support mechanisms, rheology, sedimentary characteristics, and flow state are commonly used.Different types of deep-water gravity flow events form different types of gravity flow deposits. Sediment slump retransportation mainly forms muddy debris flows, sandy debris flows, and surge-like turbidity currents. Resuspension of deposits by storms leads to quasi-steady hyperpycnal turbidity currents （hyperpycnal flows）. Sustainable sediment supplies mainly generate muddy debris flows, sandy debris flows, and hyperpycnal flows. Deep-water fans, which are commonly controlled by debris flows and hyperpycnal flows, are triggered by sustainable sediment supply; in contrast, deep-water slope sedimentary deposits consist mainly of debris flows that are triggered by the retransportation of sediment slumps and deep-water fine-grained sedimentary deposits are derived primarily from fine- grained hyperpycnal flows that are triggered by the resuspension of storm deposits. Harmonization of classification schemes, transformation between different types of gravity flow deposit, and monitoring and reproduction of the sedimentary processes of deep-water gravity flows as well as a source-to-sink approach to document the evolution and deposition of deep-water gravity flows are the most important research aspects for future studies of deep-water gravity flows study in the future.展开更多

In the years immediately following these key events, protected area acts and regulations were strictly applied and the role of local people in managing natural resources was neglected. However with the passage of time, and with changes in the socio-political and economic characteristics of Nepal, management regimes have shifted towards a more liberal model which recognizes more clearly the contributions of people living and working within protected areas. Recently, landscape level conservation models including the designation of multiple use areas have been utilized in the development of management plans for protected areas in Nepal. Conservation agencies have attempted to tackle challenges such as land use conflict, poaching and smuggling of wildlife parts and illegal harvesting of highly valued medicinal herbs through regulation, but these efforts are not always successful. We recommend a holistic conflict resolution approach which recognizes and resolves the different needs of all stakeholders.展开更多

Methods： PubMed, EMBASE, CBM, CNKI, VIP and Wanfang Databases were searched for papers on a range of terms relating to CFT. 41 references were finally selected for this review. Results： The development of CFT is comprised of five important periods in Chinese history. They axe as following： the infancy period represented by the idea of homogeny of medicine and food; theoretical development period represented by Inner Canon of Yellow Emperor, Shennong 1＇ Classic of Materia Medica and Treatise on Febrile and Miscellaneous Diseases; specialized volumes on CFT represented by Dietotherapy Worth a Thousand Gold; representative monographs on CFT represented by Dietetic Materia Medica and Principles of Correct Diet and the perfect period represented by integration of ancient food therapy practice and modern nutriology. Conclusion： CFT harbors a long and profound history, making great contribution to people＇s health maintenance and illness prevention. With the further development of integrative medicine, CFT may play a more important role in clinics and family health care based on integration of syndrome differentiation and disease differentiation.展开更多

According to its nation condition, China should design and build the launching project facility and device which correspond to the technology development of spacecraft and carrier rocket.
文摘Based on representative blasting engineering examples,the development history of engineering blasting in China since 1950 s was reviewed,three development phases were summarized,and the main achievements of fundamental theory,engineering practice,scientific study and industry organization of engineering blasting in each phase were introduced briefly.Finally,some suggestions about the development direction of engineering blasting in China were given.
文摘Objective： This review introduced the origin, developing course and modern application of Chinese food therapy （CFT） in traditional Chinese medicine to enrich our understanding of relevant concepts and ways. Methods： PubMed, EMBASE, CBM, CNKI, VIP and Wanfang Databases were searched for papers on a range of terms relating to CFT. 41 references were finally selected for this review. Results： The development of CFT is comprised of five important periods in Chinese history. They axe as following： the infancy period represented by the idea of homogeny of medicine and food; theoretical development period represented by Inner Canon of Yellow Emperor, Shennong 1＇ Classic of Materia Medica and Treatise on Febrile and Miscellaneous Diseases; specialized volumes on CFT represented by Dietotherapy Worth a Thousand Gold; representative monographs on CFT represented by Dietetic Materia Medica and Principles of Correct Diet and the perfect period represented by integration of ancient food therapy practice and modern nutriology. Conclusion： CFT harbors a long and profound history, making great contribution to people＇s health maintenance and illness prevention. With the further development of integrative medicine, CFT may play a more important role in clinics and family health care based on integration of syndrome differentiation and disease differentiation.
文摘Plain Language has made a great difference nowadays. As it turns out, Plain Language works effectively to express clearly, concisely and systematically. However, it is necessary for contemporary practitioners to review the origin and development of Plain Language Movement and to examine whether it has thoroughly implemented Plain Language policies in every federal document. Examining a contemporary federal document against the Guidelines for Document Designers reveals existing problems for further development.
