Structuration analysis of e-government studies: A bibliometric analysis based on knowledge maps

Considering the lack of systematic reviews on e-government research, this study includes research categories, spatial structure, research paradigms and noteworthy future topics in the domain of e-government. We collect 142 keywords from 2646 papers published in the Web of Science from 2000 to 2019 as the study object. Then, we identify four research categories: (1) technology and modelling in e-government, (2) drivers of e-government development, (3) public management and (4) governmental management. From public and government perspectives, we outline the spatial structure which includes theories and practices research and conclude four research paradigms: (1) theoretical modelling and application, (2) e-government development, (3) status of public management and (4) status of governmental management. Finally, we develop a 3D spatial map to analyse noteworthy topics and explore the well-studied themes: government-to-citizen, government-to-government and government-to-business, and the under-studied themes: government-to-civil society organisations and citizens-to-citizens, which helps scholars research e-government roundly.

Dominant Frequencies

Using a combination of theoretical modelling and experiments, seiches in a reservoir are shown to become linearly unstable due to the coupling with flow under a dam that opens and closes in response to the upstream water pressure. The phenomenon is related to the mechanism commonly attributed to generate sound in musical instruments like the clarinet. Shallow water theory is used to model waves in the reservoir, and these are coupled, by an outflow condition, to a nonlinear oscillator equation for the dam opening. In general, several modes of oscillation are predicted to be unstable, and the frequency of the most unstable mode compares well with the dominant frequencies observed in the experiments. The experiments also show a systematic variation of the amplitude and spatial structure of the oscillations with the weight of the dam, reflecting the nonlinear coupling between the unstable modes of the system.

This article contributes, in the form of theoretical discussion, to the review of relevant methods for determination of city's spatial structure through the retrospective of continuity/discontinuity of understanding their spatial structure from the school of classical sociology to the sustainable development paradigm. Particularly, authors underline significance and analyze main theories and their models (social-ecology, economics, system science and geography) in the researching of spatial structure of the cities. They conclude that urban settlements spatial structure is resultant of complex dynamically-developing processes between settlements networks and systems on the one, and also between their internal components, on the other side. In their essence, cities are not statistical category, but complex and dynamical system whose structure reflects the relations between economic, social and cultural organization of life, adapted to the geographic environment.

Structure Research

Urban spatial structure is the city in a variety of material, energy and social culture accumulation in space distribution and combination of the state. It is also the core issue of urban spatial development. Author studies China's urban spatial structure research, and find that China's urban spatial structure research mainly concentrated three times: 1980’s, 1990’s and since 2000.Research emphasis of each period is different. Through the process of urban spatial structure research, author sum up that the research in China has the following features: emphasis on urban spatial structure, advancing with The Times, etc. Authors hope this article can have the implications about the future of China's urban spatial structure research.

Understanding the concepts of innovation in regional governanceThe purpose of this paper is to present the concepts of innovation in regional governance — both their theoretical foundations and empirical dimension. The concepts proposed here are rooted in the public management model, while the idea of regional governance is based on the framework of a multi-level system of making and implementing political decisions. The article analyses definitions of innovation and the process of its implementation. This, in turn, provides a research tool for examining regional governance. The authors present a definition of innovation in public management — a sphere oriented toward meeting common needs of society, as contrasted with the market-oriented private sector. They proceed to pointing out the doctrinal sources of pursuing innovation in public management: theories of democracy, civil society, knowledge, social capital and networks. Finally, they propose a three-part analytical model for examining innovation in regional governance. The study is based on a typical scientific literature review using the following research methods: analysis, synthesis and theoretical modelling.

High-resolution 21-cm line observations in a region aroundlII= 120°,b11= +15°, have revealed four types of structure in the interstellar hydrogen: a smooth background, large sheets of density 2 atoms cm-3, clouds occurring mostly in groups, and ‘Cloudlets’ of a few solar masses and a few parsecs in size; the velocity dispersion in the Cloudlets is only 1 km/sec. Strong temperature variations in the gas are in evidence.

Space Observations

The development of the physics of the solar atmosphere during the last 50 years has been greatly influenced by the increasing capability of observations made from space. Access to images and spectra of the hotter plasma in the UV, XUV and X-ray regions provided a major advance over the few coronal forbidden lines seen in the visible and enabled the cooler chromospheric and photospheric plasma to be seen in its proper perspective, as part of a total system. In this way space observations have stimulated new and important advances, not only in space but also in ground-based observations and theoretical modelling, so that today we find a well-balanced harmony between the three techniques.
