A total of 216 questionnaires containing 33 items were used to collect information from the respondents. Multiple regression analysis was conducted to test the research hypotheses. Results of the current study revealed that there is a significant positive impact of KM infrastructure on job satisfaction and these results are in line with the results of the previous studies mentioned in the literature, and also revealed that the dimensions of KM infrastructure that has the highest effect on job satisfaction are organizational culture followed by information technology;whereas the variable of organizational structure has not significant impact on it. Results of T-test showed that there is no significant difference in the impact of KM infrastructure towards job satisfaction in favor of gender. In addition, results of ANOVA test found that there are significant differences in the impact of KM infrastructure on job satisfaction that can be attributed to age, educational level, and personal income.展开更多

First, we find that KIBS possess good prerequisites to function as vehicles in innovation distribution, the sources of innovation and the facilitators of innovation in their client firms. Second, we further discuss KIBS as the knowledge and innovation infrastructure of society in parallel with the research, educational and other public institutions. Third, we present some research policies and agenda to promote the development of KIBS. It is regarded that much remains to be studied both in the use of KIBS and in their own activities, including integrating and networking the knowledge-intensive services into the client companies, the convergence of various services and closer connection with the client companies＇ strategy, and the national policies to connect the KIBS to the different sectors.展开更多

The bibliometric analysis summarized output, geographical, and institutional patterns, as well as research directions and hotspots in groundwater studies in China in the period of 1984-2014. A total of 1 396 groundwater-related dissertations including 1 161 master dissertations and 235 doctoral dissertations, contributed by 128 institutions distributed in 53 cities nationwide, were searched out in the database. It can be seen obviously that, the groundwater science teaching and research in China has experienced a notable growth in the past three decades especially during 2000-2014. Groundwater modeling, resource, and exploitation were the top three major subject categories; China University of Geosciences(Beijing), Jilin University and Chang’an University were the top three productive institutions together accounting for more than one third of the total dissertations and 50% of the doctoral dissertations, which further prompted the cities(Beijing, Changchun, and Xi’an) to become the top three productive cities. The dissertations generally covered all the international research topics, which indicated that hydrogeologists in China have tracked the international frontier closely during the past decades. The keywords analysis revealed that,(1) numerical modeling was still the hottest topic and PHREEQC, MODFLOW, GMS, and FEFLOW were the four most used softwares;(2) the topics related with groundwater pollution and quality developed steadily and rapidly;(3) environmental isotopes and GIS were frequently used tools for hydrogeological condition analysis, and spatial data processing respectively; and(4) the unsaturated zone as an integral part of aquifers attracted more and more attentions from hydrogeologists focus on saturated zone.展开更多
