Since taking office, US President Donald Trump has adopted an ＂America First＂ strategy but has yet to specify a clear S＆T innovation policy. However, Trump＇s current policies have already affected S＆T innovation and his planned budget cuts will impact US growth potentials. Compared with the US, China is steadily implementing its innovation-driven development strategy with significant improvement in S＆ T innovation that increasingly supports economic growth. To spur future economic growth, China should steadfastly follow its S＆T innovation strategy, promote the utilization of S＆T innovation results, boost its economic growth potentials and make the most of global innovation resources.展开更多

However, they have been experiencing high annual rates of loss in many parts of the world. In order to evaluate a long-term wetland conservation strategy that compromises urban development with comprehensive wetland ecosystem management, remote sensing techniques were used to analyze the changing mangrove distribution in the Zhanjiang Mangrove Forest National Nature Reserve. Between 1991 and 2000, the mangrove area within the study region declined from 2 264.9 to 2 085.9 ha consistent with an annual decrease of 0.79%. However, there was an overall 34.3% increase in mangrove coverage from 2 085.9 to 2 801.8 ha between 2000 and 2011. Major causes of forest loss include local human pressures in the form of deforestation, conversion to agriculture, and natural forces such as erosion. The recent gain in mangrove forest cover is attributed to eff ective conservation management in the nature reserve area, including intensive mangrove plantation eff orts and increased local awareness of wetland conservation.展开更多

Herein, we present a facile method for the preparation of photo-luminescent CQDs using humins as the carbon precursor for the purpose of providing a high value-added solution for this “biomass conversion process waste”. The structure of the CQDs was analyzed, and the effects of reaction temperature and time on the CQDs’ ？uorescence were investigated. The results showed that humins were effectively carbonized during the reaction. The ？uorescence intensity of humin-based CQDs initially increased with reaction temperature and time, and subsequently decreased beyond 200℃ and 4 h. Polyaromatic structures and hydrophilic groups such as O-H, C-O, -COOH and C==O groups exist in the CQDs. The humin-based CQDs have the dimension of 3~7 nm with an average size of about 5.5 nm. The highest emission intensity of blue/cyan ？uorescence light at 440 nm is achieved on the excitation with UV light at the wavelength of 330 nm.展开更多

Firstly, the process of innovation is generalized to seven stages including formation of innovation idea, investigation and evaluation, research and development, middle test, mass production, marketing and selling, after service and feedback. Secondly, the origin of risk in the process of innovation is analyzed. The purpose is to help enterprise identify risk and take countermeasure to minimize the potential loss and maximize the potential income.展开更多

An invention, a president, the occurrence of an organization, a historical lesson may directly or indirectly change accounting regulations, and even trigger an accounting revolution. We will put a variety of significant impacts on an accounting, so as to get a fundamental understanding of the close relationship between such events and accounting events, including innovation of accounting theory, and accounting practice; we adopted the ＂table-style＂ form of papers, with many self-evident and intuitive tables, we compile a series of major historical events reasonably. Only in accordance with evolution of objective environment, can we design proper accounting practice, and thus innovate and develop accounting.展开更多

Piggery was established to combine science and technology to generate innovations for anyone seeking to establish a new pig production enterprise. Results show that since 2008 to 2013, pork prices in Ghana rose rapidly between 115-120%. Also the rate of returns was higher at 43.62% compared to bank interested rate. Feed, as a percentage of total costs, were minimised from 70% to 55% with integrated lactobacillus brewer spent malt as supplement to formulated feed. The piggery project was highly successful and invested capital was recouped within two years of project take-off. Collaborating with other farms, organisations and entrepreneurs, a lot of research innovations in the area of improving feed cost, animal nutrition, waste management practices, and breeding have been generated and shared with both small and large-holder pig farmers. In all aspect of the farm management, results achieved so far especially with pork carcass quality and profit margins are encouraging which have led to the expansion of the piggery project.展开更多

Firstly, this paper analyzes the development status of equipment manufacturing industry in Shanghai, and then uses DEA to analyze the efficiency of technology innovation capability of equipment manufacturing industry in Shanghai. The results show that the equipment manufacturing industry in Shanghai has stronger overall drawing ability, and besides, the technology innovation ability of the transportation equipment manufacturing industry is weak, other equipment manufacturing sub industries have relatively strong ability of technological innovation. This paper analyzes the shortcomings of the transportation equipment manufacturing industry and gives guidance and puts forward corresponding suggestions and measures.展开更多
