The identification of relevant routines as well as the understanding of which factors affect business innovation is the main objective of this research, based on a survey applied in Portuguese companies and their experience shared in best practices guides. Conclusions highlighted 10 key innovation routines, reinforcing the idea that innovation must be supported through a systematic and sustained management process. Results also indicate that SMEs face greater difficulties in benefiting from the potential of innovation practices and collaboration may present opportunities to overcome their limited resources. Therefore, regardless of size, business activity, science and technology intensity or other factors influencing firms dynamic capabilities, innovation should be considered as a management imperative as it can influence not only the present but also the future of business success.展开更多

Innovation is not a new concept, but its perception as a process, detached from randomness, is. This understanding is what allows its management as a tool to improve results and competitiveness, and to the perpetuation of the company. The research had a qualitative approach that consisted in the content analysis of structured interviews held with 10 respondents of five different companies, using eight innovation-focused questions, adapted from the Brazilian National Quality Foundation （FNQ）. After interviews, four categories were identified： innovation understanding, innovative ambience, innovation process management, and learning during the process--the first two regarding the subjective features of innovation and the latter two the objective features. Analysis outcome has shown that companies understand the concept and importance of innovation, but still do not see it as a process, which leads them to try isolated initiatives, usually executed by instinct only. Due to the fact that innovation is not considered as a process, most practices encourage generation of ideas, instead of goals, key performance indicators （KPIs）, and learning--this latter one, only occurs informally and over time.展开更多

Although the agricultural product processing industry has become the bright point in Chinese economy development, the whole development level falls behind the developed countries. The thesis brings up that the inherent reasons that Chinese agricultural product processing industry falls behind is that Chinese agricultural product processing industry has not an integrated industrial innovation system and has not a proper innovation strategy. So this thesis deeply discusses how to construct innovation system of Chinese agricultural product processing industry and puts forward the innovation strategy in order to improve the technology innovation capability and the development level.展开更多

In the reactor, heterotrophic bacteria （including sulfate reducing bacterium and denitrifying bacteria） and autotrophic bacteria （ including Thiobacillus denitrificans） cooperated together by incubating and enriching functional bac- teria on different carriers in the anaerobic activated sludge. Synthetic wastewater with high concentrations of sulfate and nitrate was employed. The experimental resuhs showed that the removal efficiency of sulfate and nitrate was above 85% , elemental sulfur was observed while nitrate was absent in effluent. The balance of sulfur, nitrogen and electron was discussed respectively, which indicated that the integrated SDD process could be actualized. These resuhs might provide a guidance to further investigate the key factors affecting the integrated SDD process and to improve the efficiency of desulfurization and denitrification in wastewater treatment.展开更多

It draws upon a creativity process that considers three ＂dimensions＂ or ＂disciplines＂ （3D） critical for creative organizations--within discipline expertise, out of discipline knowledge, and a disciplined creative process. The paper first explores the Cobb-Douglas production function as a relevant tool for modeling the 3D creative process. The next part discusses the 3D process as a production function, which is modeled following the well-known Cobb-Douglas specification. Last, the paper offers implications for future research on disciplined creativity/innovation as a method of improving organizations＇ creative performance. The modeling shows that labor and investment can readily enter into the 3D creativity process as inputs. These two inputs are meaningful in explaining where innovation outputs come from and how they can be measured, with a reasonable theoretical decomposition. It is not true that the more capital investments in the creativity process, the better the level of innovation production, but firm＇s human resource management and expenditures should pay attention to optimal levels of capital and labor stocks, in a combination that helps reach highest possible innovation output.展开更多

According to the previous practical experience, the feasibility of the implementation of raw gangue filling mining technology in the coal-pressed area was analyzed. Through the filling gangue compaction test, the deformation under different loading stages was obtained. Further, a reasonable prediction of the deformation beyond the experimental limited loading load was made based on the experimental results. Through the deformation source analysis of the whole process of gangue filling, the key factors for controlling deformation before, during, and after filling were determined. Additionally, the proportion of deformation during different stages was quantified. Considering the protection of surface buildings, mining fullness of the working face and mining technology, the production parameters of 1209 and 1210 filling working faces were preliminarily determined. Through numerical simulation, the rationality of mining scheme was verified. Based on the practice of 1209 working face and the key factors to control the deformation of gangue filling, the mining system and process in 1210 working face were optimized. According to the measured surface rock movement, raw gangue filling mining technology can meet the requirements of surface building protection level. Especially, this paper provides a method to quantitatively calculate the equivalent mining height (EMH) of raw gangue filling and its mining deformation, which has reference significance for old mining areas.展开更多
