"Without an appropriate research setting, a study cannot be qualified as a reasonable piece", this notion is manifested in the methodological polices. In this research, we attempt to examine previous studies within the scope of technology evolution and market perception in telecommunication industry through extracting research structures, methodologies, corresponding variables, and processing methods. A general process of social scientific research is adopted to analyze eighty-four selected papers; and simultaneously, the framework for doing this analysis is established, as well. In this manner, we inspect the subjects and the issues in these papers according to product types, academic domains, and divisions of technological evolution (from 1G to 4G). Then, their research designs are anatomized into the key dimensions of general research conventions. This research eventually provides an entire picture of a research scenario for mobile telecommunication industry; and apparently, this framewbrk can help scholars to establish specific tendencies for academic scenarios in future research plans. Also, we propose the main streams and emerging issues can be expected to engage in the future within both theacademic and the operational fields. 展开更多

The supply of logs for wood industries during the period 2004-2008 was 13.5-32 million cubic meters per year. Logs from plantation forest reached about 65%, which was exploited from industrial plantation forest, Perum Perhutani, as a government enterprise, community forest and estate. The changing log supply from natural forest to plantation forest implies changing of wood species, cutting cycle, log diameter and wood properties. Research concerning the utilization of fast growing species, small log diameter, lesser used species and other llignocellulosic material have been intensively done by some research institutes and universities, and were related to wood properties, wood properties enhancement, wood chemistry, bio-composite, wood engineering, and also non-timber forest products. 展开更多

As an important foundation for promoting social progress and economic development, natural resources play an important role in the sustainable development of cities. However, the increasing demand of human beings for natural resources has led to various ecological environmental problems, such as excessive population density, serious environmental pollution, the continuous decline of total natural resources and per capita resources, all of which have hindered sustainable development. Therefore, the study of natural resources and sustainable development has become the focus of many current scholars. In this paper, CiteSpace is used as an analysis tool to analyze the literature on natural resources and sustainable development over the past 20 years. First of all, this paper deeply analyzes the research status of this field in terms of academic research trends, authors and research institutions, co-occurrence of keywords, etc., and on this basis, it then deeply analyzes its evolutionary path and research hot spots in the past 20 years through keyword emergence. Finally, according to the visualization of the analysis results, the future development trends of this research field are speculated:(1) Grasp the current research focus;(2) Improve the research accuracy;(3) Enrich the theoretical system of research;and(4) Establish an interdisciplinary research system. 展开更多

American Studies, as a dynamic field of research throughout the world, has its fair share of ebb and flow. Its emergence in the US indicates the national appeal of America, and its emergence across the world corresponds to the expansion of the USA's influence and power. Vertically, it is experiencing a process of subdivision; while horizontally, it has undergone changes and variations. American Studies in the US is characterized by its focus on American culture and society. American Studies in China is more of an exoscopic type of research concerning "the Study of America," which is the research on another pohtical entity. In addition to language and economic factors, the combination of nativism and national interests determine the variation of American Studies across the globe. This article also retraces the path of development of American Studies in China since 1979, and attempts to sum up the characteristics and the weaknesses in American Studies dealt with in China. 展开更多

The progress in the science of energy utilizations will act crucial effect on the developments of energy science and technology, which will then promote social and economical developments and fulfill requirements for the national strategic objectives. For the sake of sustainable development, a harmonious blend of energy utilizations and environment considerations will become one of the vital topics in the future research area of energy science. It is suggested that clean and high-efficiency utilization of traditional or fossil energy resources, fundamental investigations on the energy and environment theory, renewable energy utilizations, and the development of nuclear energy are selected as priority research areas during the period of the Tenth Five-year Plan of China, according to the development trend of the world energy science and the research background of Chinese energy science, It is expected to promote the interdisciplinary investigations in the science of energy utilizations and provide scientific and technological supports for the development of related advanced high technologies, 展开更多
