Based on the theory of sustainable development and the connotation of national park, this paper will discuss the signifi cance of establishing Chinese National Park System and then propose some measures. Chinese National Park System can be constructed from four levels, including policy, management, economic and social levels, and through such ways as reconstructing the national conservation system, making laws and regulations, establishing planning system, setting up independent and specialized regulatory agency, adopting way of franchising, innovating funding investment mechanisms and establishing mechanisms of public participation.展开更多

This is true for Nursing as a discipline of knowledge and a practicing profession. Nevertheless, should all science or research within a scientific field be focused on theoretical development and testing? Currently, various nursing theories exist to describe and explain the phenomena of nursing. Often, the development of nursing theory is in response to advancing ontologies and epistemologies of nursing. The advent of technology is one of these advances challenging the professional practice of nursing. How will nursing practice be made visible and realistic in the face of traditional nursing care practice? Nursing practice processes, derived from theories of nursing, provide opportunities for demonstrating practice grounded in the science of nursing. The purpose of this article is to describe the development of the emergent theory of Aesthetic Nursing Practice, focus on illuminating caring for person through the process of encountering, co-creating caring relationships, and meaningful engaging between the nurse and nursed through caring encounters occurring in caring situations. Five assumptions and a model of practice are described. As a contemporary theory of Nursing, it describes caring for persons who remain wholes and enhance their well-being.展开更多

So it seems necessary to attack the same task on the reverse, namely to measure the passibility of eatostrophe. In this paper, with a case study of Tianjin, China. we employ catastrophe theory and models to integrate Tianjin's sustainable development indicators, and then deduce the catastrophe risk index ( CRI) to present the level of catastrophic possibility in the city. Applying catastrophe theory, is a new strategy to assess sustainable development and shows great practical significance, especially for those developing regions or countries, who always give more priority to their economy and therefore have more obligation to make sure whether their social economic activities might bring forth any ecological environment catastrophe. Besides, being both qualitative and quantitative, the approach could be employed to explore not only static characteristics bat also dynamic mechanism of man-land system. Although our work is only a maiden attempt and still calls for further effort to improve it, the case study of Tianjin in this paper would assure as the great promising future to apply, catastrophe theory to sustoinable devetopment modeling,展开更多

In addition, the task was to develop a model for forecast calculations of labor productivity in the symbiosis of “man + intelligent machine”, where an intelligent machine (IM) is understood as a computer or robot equipped with elements of artificial intelligence (AI), as well as in the digital economy as a whole. In the course of the study, it was shown that in order to implement its goals the Schumpeter-Kondratiev innovation and cycle theory on forming long waves (LW) of economic development influenced by a powerful cluster of economic technologies engendered by industrial revolutions is most appropriate for a long-term forecasting of technological progress and economic growth. The Solow neoclassical model of economic growth, synchronized with LW, gives the opportunity to forecast economic dynamics of technologically advanced countries with a greater precision up to 30 years, the time which correlates with the continuation of LW. In the information and digital age, the key role among the main factors of growth (capital, labour and technological progress) is played by the latter. The authors have developed an information model which allows for forecasting technological progress basing on growth rates of endogenous technological information in economics. The main regimes of producing technological information, corresponding to the eras of information and digital economies, are given in the article, as well as the Lagrangians that engender them. The model is verified on the example of the 5<sup>th</sup> information LW for the US economy (1982-2018) and it has had highly accurate approximation for both technological progress and economic growth. A number of new results were obtained using the developed information models for forecasting technological progress. The forecasting trajectory of economic growth of developed countries (on the example of the USA) on the upward stage of the 6<sup>th</sup> LW (2018-2042), engendered by the digital technologies of the 4<sup>th</sup> Industrial Revolution is given. It is also demonstrated that the symbiosis of human and intelligent machine (IM) is the driving force in the digital economy, where man plays the leading role organizing effective and efficient mutual work. Authors suggest a mathematical model for calculating labour productivity in the digital economy, where the symbiosis of “human + IM” is widely used. The calculations carried out with the help of the model show: 1) the symbiosis of “human + IM” from the very beginning lets to realize the possibilities of increasing work performance in the economy with the help of digital technologies;2) the largest labour productivity is achieved in the symbiosis of “human + IM”, where man labour prevails, and the lowest labour productivity is seen where the largest part of the work is performed by IM;3) developed countries may achieve labour productivity of 3% per year by the mid-2020s, which has all the chances to stay up to the 2040s.展开更多

文摘The report of the 18th National Congress of the Communist Party of China (CPC) set "respecting and ensuring human rights" as an important goal of development and reform in China, thus siniciz ing the latest Marxist human rights theories and reflecting major in novations and developments made by the CPC in the field of human rights theory. I. Human Rights as a Core Idea and Important Goal of Social Development Human rights are integral to the pursuit of the core value of socialism and to the core idea of socialism with Chinese characteristics. The report of the 18th CPC National Congress summarized the new progress and experience of human rights advance ment in recent years in China by setting "respecting and ensuring hu man rights" as an important goal of China as it completes the building of a moderately prosperous society.
文摘The reasons for choosing this topic are two: 1) Vocabulary development is the primeconcern for both learners and teachers of a foreign language; 2) Personal teaching experiencehas often challenged me with the question how to develop vocabualry more effectively. Thegeneral objective of this writing is to generalize some enlightening information on the specificarea of vocabulary learning and instruction and to bring forward some ideas practical to ourteaching situation.

文摘The study draws on the prevalent theories for orchestrating cross-organizational innovation and new knowledge development processes,and proposes a new,epistemic perspective for contextualizing innovation with two management dimensions,namely,innovation complexity and innovation orchestration preconditions.Innovation complexity concerns the indeterminacy or contingency of new knowledge,or new competence,to be pursued during the course of organizational innovation.Innovation orchestration preconditions refer to the contextual innovation prerequisites that should be well meshed with one another to provide a sufficiency for innovation success.The preconditions include innovation units’structures and connectivity,behavior,and convenorship.The two dimensions describe a context map-an antithetic quad model-to imply four innovation orchestration qualities,namely,coherence,cohesiveness,congruence,and concordance.Based on the quad model,the study sets forth a measurement of the four qualities,which can assess innovation potential.To corroborate the quad model and the corresponding quality measurements,the study discursively observes a cross-sectoral innovation project.The observation results evidence the multi-finality of the four qualities for innovation success.The results reveal that it is necessary for these four qualities to be managed temporally and dynamically at different stages of innovation,and reject a fallacy that any one of these qualities is more necessary than the others.The study posits that if innovation units can be convened in accordance with the four qualities,the likelihood of innovation success will be sufficiently increased.The study finally discusses theoretical and practical implications of orchestration and convenorship.
