Information and communication technologies in general and the internet in particular are often praised as a means for enhancing democracy and providing new spaces for the development of an egalitarian civil society, in which all members of society can participate equally. However, there are various possibilities to monitor, manipulate and control cyberspace, of which the internet is an essential part. This paper examines the efforts of the Vietnamese government and the Vietnamese Communist Party to control cyberspace as well as the physical spaces through which the virtual world is accessed. There are attempts to control the internet in a similar fashion as the traditional print and broadcast media. Any such control is neither absolute nor without effect. Instead control is exercised in a highly flexible manner, allowing for some officially unwanted or illegal activity to occur. At the same time authorities can apply internet regulations, if it serves their political objectives as for example strengthening the Party’s official monopoly on political power. The paper traces the development of the internet as well as the regulatory environment surrounding it and analyses the inconsistent enforcement of regulations. The analysis is framed in the theoretical works of Michel Foucault and Jürgen Habermas. 相似文献
Today, online social media outlets provide new and plentiful sources of data on social networks (SNs) and location-based social networks (LBSNs), i.e., geolocated evidence of connections between individuals. While SNs have been used to show how the magnitude of social connectivity decreases with distance, there are few examples of how to include SNs as layers in a GISystem. If SNs, and thus, interpersonal relationships, could be analyzed in a geographic information system (GIS) setting, we could better model how humans socialize, share information, and form social groups within the complex geographic landscape.
Our goal is to facilitate a guide for analyzing SNs (as derived from online social media, telecommunications, surveys, etc.) within geographic space by combining the mature fields of social network analysis (SNA) and GISystems. First, we describe why modeling socialization in geographic space is essential for understanding human behavior. We then outline best practices and techniques for embedding SN nodes and edges in GISystems by introducing terms like ‘social flow’ and ‘anthrospace’, and categorizations for data and spatial aggregation types. Finally, we explore case study vignettes of SNA within GISystems from diverse regions located in Bolivia, China, Côte d’Ivoire, Singapore, the United Kingdom, and the United States, using concepts such as geolocated dyads, ego–alter relationships, node feature roles, modularity, and network transitivity. 相似文献
Internal migration rates in the United States have been steadily declining for at least twenty-five years: In 1984, 6.4 percent of the population moved between counties but by 2006—well before the most significant economic crisis since the Great Depression—annual intercounty migration rates had already declined to 4.7 percent and by 2010 to 3.5 percent. Despite the implications of the migration decline, it is poorly recognized and understood. The analysis shows that over the last thirty years, three broad trends have combined to pull migration rates dramatically lower: an increase in dual-worker couples, increased household indebtedness, and the widespread rise of information and communication technologies (ICTs). The first two are probably linked, as households have responded to decreasing real income over the last quarter-century through greater female labor force participation and maintaining current levels of consumption by borrowing ever more heavily from the equity in their homes. Thus, although this analysis shows that the decline in migration rates is not directly linked to the Great Recession, the migration decline is surely linked to the broader macroeconomic shifts that gave rise to it. With respect to the role of ICTs, it is not surprising that as ICTs have transformed nearly everything else across society, their use has affected migration rates. It is presumed that ICTs are providing new forms of mobility that are substituting for migration. 相似文献
