In our context, being professional means being the effective teacher, which is required to develop continuously throughout the whole career. Teacher professional development, in this article, mainly the issue of teacher professional self-development is discussed. In order for that to be realized, the reflective approach is bring introduced. Here, the reflective approach is primarily based on doing Action Research that includes Rettospective technique, Observation technique, Questionnaires and Interviews and Case Study.展开更多

Mean-reversion with jumps for price forecasting is used to consider market uncertainty, while various scenarios for the reservoir properties and cost are employed to consider technical uncertainty. Monte Carlo simulation is carried out to obtain the feasible range of net present values and internal rates of return. The influence of stochastic parameters is examined through correlation coefficients. The stochastic approach yields more reliable evaluation and effectively investigates the characteristics of development. The integration of uncertainties and contractual terms results in an irregular tendency in the future cash flow and reveals that a larger reserve does not guarantee a greater profit. The reserve and the well rate affect the economic values whereas the parameters for price prediction don't. The research confirms the necessity of qualifying uncertainties for realistic decision-making at the initial stage of development.展开更多

Cities are where most people live, urbanization is a strong upward global trend, and cities bring all these problems into sharp, compelling focus. Since outcomes stem from processes and systems, we argue transformative changes depend on re-imagining the Urban Design, Urban Planning and Urban Development Practice (UD/UP/UDP) process. While there has been insufficient attention to process innovation— with technological aspects tending to dominate UD/UP/UDP work—emerging systems views of cities, and disenchantment with existing modes are enabling. We propose an empirically based integrative frame to tackle recognized conundrums, and inform an adaptive UD/UP/UDP process—from concept through design, assessment, planning, implementation, project functioning and monitoring. The frame contemplates six domains (6-D): 1) Project ethos, concept, and framing;2) sectors, topics, and issues;3) Varying spatial and temporal scales;4) Stakeholder interests, relationships and capacities;5) Knowledge types, modes and methods;and 6) Socio-technical capacities and networks. The frame, process and outcomes constitute a socio-technical enterprise (STE) approach to UD/UP/UDP work, with implications for education, training, and professional practice. We highlight the pivotal role Integrators and Universities play, and the scalability of STE knowledge/capacity networks. The case of Greater Mexico City/Central Mexico Urban Region illustrates the utility of the approach in a hyper-complex, climate-change vulnerable regional context.展开更多

Since reform and opening up in 1978, China has persisted in the central task of economic development and put development in the first place. The evolution of the concept "development is the hard truth" to "development is a task of first importance in governing the country and invigorating the Chinese nation" and to the establishment of the scientific development approach reflects the deepening and growing command of the laws governing China's economic and social development.展开更多

Up to now, low carbon agricultural development approaches are lacking of deep and systematical researches. Therefore, the paper briefly analyzed the situation and the existing problems of China's low carbon agricultural development, and then put forward the approaches to promote the low carbon agricultural development.展开更多

In contrast to the central nervous system (CNS), the adult PNS retains a remarkably high degree of intrinsic re- generation. As a consequence, transected axons and dam- aged myelin sheaths can be repaired and nerve functional- ity can be restored. This spontaneous regenerative capacity depends on (inter) actions of macrophages, neurons, and Schwann cells.展开更多

The large number of software projects not meeting their expectation in terms of functionality, cost, delivery schedule and effective project management appears to be lacking. In this paper, we present a new software fusion process model, which depicts the essential phases of a software project from initiate stage until the product is retired. Fusion is component based software process model, where each component implements a problem solving model. This approach reduces the risk associated with cost and time, as these risks will be limited to a component only and ensure the overall quality of software system by considering the changing requirements of customer, risk assessment, identification, evaluation and composition of relative concerns at each phase of development process.展开更多

This is one of the possible modern avenues to success, especially the use of the biotechnologies that are so touted by Western countries. However, the hope placed in these new technologies must not hide the long-proven fact that technology alone is not enough to solve development problems. Biotechnologies do not escape this rule. Biotechnologies can be the best and the worst things for the people of Africa. Beyond their technical contributions, we must be wary of their boomerang effects and collateral damage. A country’s development is actually more complex than simply implementing technology, and in the current global environmental context a holistic vision is necessary to ensure sustainable development. In the area of water, this integrated vision emerged on the international scene during the Dublin Conference in 1992, which consecrated the principles of Integrated Water Resources Management (IWRM). More recently, the Eco-Health concept strives to combine human health and ecosystem health while incorporating a socioeconomic dimension into the health and environmental spheres. The concern to mesh human activities better with environmental protection was materialized previously, in the 1970s already, through impact studies. After presenting this set of tools in the service of a holistic approach to the environment and development, we shall see that these approaches can inspire the players when it comes to the ways they implement biotechnologies. At the end of the day, a holistic approach to biotechnologies in Africa will be facilitated by enhanced information and communication and reliance on peasant farmers’ expertise. It will have to be rooted in broader participation of the players concerned. This integration will also concern environmental and land-owning aspects, without forgetting socio-cultural acceptance of the projects and the links with health. Ultimately, it will also mean putting the human at the heart of development by taking all the richness and particularities of African society into account.展开更多

This paper, by making a diachronic analysis on their courses of development, tries to justify the importance of adopting an economic institution suitable to the situation of a country.展开更多

Current approaches from different disciplines can be grouped into at least three levels: micro-scale, meso-scale and macro-scale. At the micro-scale, green chemistry carries out chemical activities such as chemical design and synthesis so that environmentally benign chemicals can be synthesized without using and generating hazardous substances. Green engineering, at the meso-scale, develops green industrial processes or clean technologies via pollution prevention and cleaner production, which will cause minimal damages or dangers to the environment and ecosystems when the product is manufactured and used. Industrial ecology at the industrial complex or community level seeks to optimize energy and materials use and minimize waste generation in industrial systems or communities by promoting planned materials and energy exchanges. Incorporation of ecological principles with the life cycle thinking in the chemical pathway synthesis, product design, process development, and industrial system and community planning appears to be the most promising engineering approach in achieving sustainable industrial development.展开更多
