Since the conception of sustainable development was advanced. its basic meaning has been extensively accepted. Sustainable development is a focus that all social circles pay close attention to In general, sustainable development is to satisfy the needs of contemporary era. but not to damage the requirement of later generations. It is quite evident that we should correctly handle the issues of interera retationship. In this paper, the authors have made a preliminaly approach to the inter-ere fair by calculating the coordinated degree of a city and accounting the resources' depletion. 展开更多

On the basis of scientific practice,Marx scientifically illustrated the three phases of human development,and put forward that"individual character"is the highest stage of development.He correctly revealed the man's all-round development thought and implementation approach.As a theoretical source and logical starting point,Lenin combined it with real life.On the one hand,Lenin developed Marx's people theory into a more specific"overall development of individuals"generally,and improved the practical level;on the other hand,he self-consciously implemented the thought in practice so that Marxist theory was pushed to a higher new state. 展开更多

The development, cytological characters and ultrastructure of phloem ganglion in the nodal region of Phyllostachys edulis (Carr.) H. de Lehaie, a most economically important bamboo, were investigated and the possible physiological function of this special structure was proposed. The phloem ganglion derived directly from procambium is situated at the sites where the vascular bundle forks and is present in pairs. The phloem ganglion is spindle_like in appearance and usually consists of 4 to 6 layers. Two kinds of cells in the ganglion could be distinguished. In the middle, there are two layers of filiform cells with pointed ends so that there are no normal sieve plates. Nevertheless, there are many pits on the lateral wall of the filiform cells. The other type of cells located at both ends of the spindle which possess an intermediate form between the filiform cell and the normal sieve tube. The walls of these cells towards the filiform cells are strongly convex forming a special sieve plate. Ultrastructure study showed that cells in the ganglion are connected by enriched plasmodesma. During early differentiation, the paramural body and the ingrowth of cell wall could be observed. It indicates that the cells of phloem ganglion have the character of transfer cells. The organelles in the mature cells are mainly plastids with abundant accumulation of proteins of crystalline structure. The above_mentioned results suggest that the physiological function of the phloem ganglion is closely related with substance transport. 展开更多

Various individual organs (tepal, flower bud, inflorescence branch, inflorescence, adult vegetative bud and juvenile vegetative bud) were directly regenerated respectively by callus in Dracaena fragrans cv. massangeana Hort. During the regeneration of these individual organs some regularity phenomena were observed. Firstly, the kind range of the individual organs, which are directly regenerated in vitro, is in close relationship to the differentiated stages of the organs used for explant excision during plant ontogeny. The explants excised from the epigeous organ that is differentiated at some stage (stage A) during plant ontogeny must be able to separately regenerate all of those individual epigeous organs: ones differentiated slightly later than the stage A, ones differentiated at the stage A and all ones differentiated earlier than the stage A. Secondly, within this range which kind of organ is regenerated depends on the exogenous auxin concentrations in medium. With the gradual increase of 2,4-D concentration from 0.005 mg/L to 0.5 mg/L, the kinds of regenerated organs will change by the order as follows: vegetative bud, inflorescence, inflorescence branch, flower bud, tepal. These regularities will be able to be used for inducing the direct regeneration of a given epigeous organ in angiosperms. 展开更多

Governments settle their financial obligations and pay for the public expenditures largely through finances generated from taxes.For many developing countries like Pakistan,the state authorities are still having difficulty to achieve tax compliance.Existing literature has yet to traverse individual’s tax compliance behavior on developing countries.The current study,however,explores the relationships among voluntary tax compliance behavior of individual taxpayers with selected economic,social,behavioral and institutional factors.This individual tax compliance behavior is studied through the multi-perspective lenses of the theory of attribution,equity theory,expected utility theory,and social exchange theory.Quantitative design using the survey method was employed to collect data from 435 individual taxpayers through questionnaire.For testing linkage between constructs,through mediation and moderation tests,structural equation modeling technique was used.The results suggest that tax compliance simplicity has a larger impact on tax filing than perception about Government Spending and tax morale.Furthermore,perception of fairness significantly mediates the strengths between morale,simplicity,government spending and compliance behavior. 展开更多

Introduction: The author strongly believes that there is a continuous need for personal and professional development in order to keep and improve an individual career path way. It is also imperative to provide evidence of these acquired skills and attributes. According to General medical council, it is a responsibility of every doctor to be competent and up to date. This should be achieved by regularly taking part in activities that maintain and further develop competence and performance. This in turn ensures safety and care to patients [1]. Methodology: The author has had excellent opportunities in his career to participate in diverse personal and professional development programmes. It was important to participate in these programmes to achieve career progression. He would like to share three recent activities from his curriculum vitae which resulted in his significant personal and professional development. The author also had his revalidation last year and found to be fit to practice for next 5 years till next revalidation. The author followed an agreed action plan with his supervisor to accomplish this work. Realistic goals and time frame was set with the help of supervisor. Subsequently, the author had a chance to critically analyse below mentioned three different activities, in order to explore all the achieved learning themes behind these events. The author was fortunate enough to be involved into three different personal and professional development programmes. Firstly, he managed a regional colorectal conference and attained an excellent management experience from that conference. He learnt a lot about better time management. He came to know about different management theories and models and is now able to use these theories for his future management responsibilities. Then he had a communication challenge and difficulty in theatre. He was able to resolve that issue with his strong communication skills. He developed his communication skills and assertiveness with the help of this first-hand experience and different communication models. Lastly, the author had a wonderful opportunity to demonstrate and develop his leadership and team working skills in an International Conference. He realized that leader needs to be a role model for his team and should be leaded by his example. He observed and demonstrated different roles of a leader according to needs of his team. He also learnt about different leadership theories and models. He also acquired a good understanding of a team development. Conclusion: It is extremely important for every health care individual to have personal and professional development. The author recommends that lessons learnt from the author’s experience and results can be applied in a broad generalised way to achieve development. It is crucial for us to keep a structured record of this development and provide evidence of the improvement. In short, it was an extremely useful exercise for the author that resulted in significant lifelong development in his management, communication and leadership attributes. 展开更多

Make up for deficiencies in the economic development of market mechanisms through macro-control method. Although the market plays a fundamental role in resource allocation, in other means of regulation it plays an irreplaceable role in regulating the economy, the management of economic activities. However, by the market "invisible hand" spontaneous adjustment, there is "market failure" problem. Market self-regulation mechanisms inevitable cyclical economic fluctuations and economic crisis, the impact of a sustained and stable economic growth will lead to a waste of resources, environmental degradation is caused, but also it produces uneven regional development, causing social polarization between rich and poor, etc. Public goods such as ecological environment should be through legal means, rather than a means to implement the healthy development of the market environment. 展开更多

The crowdsourcing, as a service pattern in cloud environment, usually aims at the cross-disciplinary cooperation and creating value together with customers and becomes increasingly prevalent. Software process, as a kind of software development and management strategy, is defined as a series of activities implemented by software life cycle and provides a set of rules for various phases of the software engineering to achieve the desired objectives. With the current software development cycle getting shorter, facing more frequent needs change and fierce competition, a new resource management pattern is proposed to respond to these issues agilely by introducing the crowdsourcing service to agile software development for pushing the agility of software process. Then, a user-oriented resource scheduling method is proposed for rational use of various resources in the process and maximizing the benefits of all parties. From the experimental results, the proposed pattern and resources scheduling method reduces greatly the resource of project resource manager and increases the team resource utilization rate, which greatly improves the agility of software process and delivers software products quickly in crowdsourcing pattern. 展开更多

Background: A novel approach to modelling individual tree growth dynamics is proposed. The approach combines multiple imputation and copula sampling to produce a stochastic individual tree growth and yield projection system. Methods: The Nova Scotia, Canada permanent sample plot network is used as a case study to develop and test the modelling approach. Predictions from this model are compared to predictions from the Acadian variant of the Forest Vegetation Simulator, a widely used statistical individual tree growth and yield model. Results: Diameter and height growth rates were predicted with error rates consistent with those produced using statistical models. Mortality and ingrowth error rates were higher than those observed for diameter and height, but also were within the bounds produced by traditional approaches for predicting these rates. Ingrowth species composition was very poorly predicted. The model was capable of reproducing a wide range of stand dynamic trajectories and in some cases reproduced trajectories that the statistical model was incapable of reproducing. Conclusions: The model has potential to be used as a benchmarking tool for evaluating statistical and process models and may provide a mechanism to separate signal from noise and improve our ability to analyze and learn from large regional datasets that often have underlying flaws in sample design. 展开更多

The phenological phase, plant height, filler number, nutritional composition, yield and stem/leaf ratio of three oat (Arena sativa) varieties (lines) in winter dry land of Hunan were studied. The result shows that the three oat varieties were greatly different in plant height, nutritional composition, yield and stem/leaf ratio. Baiyan 7 had the best performance, with the plant height, tiller number and fresh yield of 101.67cm, 7.6 tiller/plant and 70.15 t/hm2 respectively ; the crude protein content of dry matter of Baiyan 7 was 32.63% ; the leaf weight per tiller of Baiyan 7 accounted for 31.6% of single tiller weight, while those of Baiyan 8 and Baiyan 2 accounted for 31.3% and 29.2%, respectively. The single tiller weight of oat could be estimated/calculated by the model/formula Y = 0.043 7X - 2.89 ( R2 = 0.913 4, P 〈 0.01 ), where Y is the single tiller weight ( g ) and X is the plant height (cm). Comprehensive analysis showed that Baiyan 7 had higher yields and stem/leaf ratio. Thus, Baiyan 7 is more suitable for planting as a winter-spring forage in the winter dry land of Hunan. 展开更多

The pursuit of economic efficiency is the major driver for the birth of contemporary Chinese civil law.Contemporary civil law scholarship has demonstrated a serious concern for efficiency from the very beginning.However,many examples suggest that the notion of economic efficiency is often diluted or replaced by factors like civil law doctrinal scholasticism,moral notions,inertial thinking of the planned economy or the will of the leader.It has not been systematically attended to or expressed in a detailed and precise way in the contemporary civil law scholarship in China,rendering some economic judgments uneconomical.In the 21 st century,it is necessary for the civil law studies to establish a clearer and more precise notion of efficiency,to conduct more direct and accurate evaluations on civil laws’incentives on people’s behaviors and their socio-economic effects,so as to reduce the cost of social interactions and promote deeper cooperation and winwin outcome among individuals. 展开更多

Recently, a great tide of English teaching reform swept across China, advocating the innovation of educational concept and teaching mode. However, the phenomenon of rigid uniformity in teaching process is still commonly seen, neglecting the individual discrepancy of students. The individual discrepancy is manifested by both the congenital heredity and the acquired disposition. Supported by the Chinese traditional theory of teaching students in accordance with their aptitude and Vygotsky's "the zone of proximal development" theory, this paper illustrates the importance of paying attention to the individual discrepancy from the perspective of students' growing background and personality. In addition, standing on the point of view of relevant authority and English teacher, the author tries to put forward some countermeasures. 展开更多
