论农村产业结构的“空间转移”

为解决农民增收问题,为适应全面建设小康社会的紧迫需要,农村产业结构必须全方位"空间转移"。作者在追述中国农村产业结构的历史状况的基础上,分析了农村产业结构"空间转移"的紧迫性、必然性和可能性,提出了培养经济增长、引进新技术、加大资本投入、加速专业化生产、加强线路建设和加强小城镇建设等对策措施。     

Older audiences in the digital media environment

Relying on Jensen and Helles’ model for studying the Internet as a cultural forum, this study aimed to explore the extent to which traditional media are displaced by innovative communication practices within the older audience of new media. The study was based on a cross-European survey of 1039 Internet users aged 60 years and up. Results indicated that older Internet users are significantly more inclined to use traditional mass media than new social media and prefer synchronous to asynchronous mass media. This audience, however, is not homogeneous, as four subsegments were identified. These groups differed in their media repertoires, sociocultural background and leisure preferences. The findings suggest that despite the increasing percentage of older Internet users, this audience tends to adhere to familiar media practices, with only a minority making intense use of new practices. With very few cross-national differences, this tendency appears to be universal, suggesting overall media use traditionalism and a second-level digital divide among the older audience.     

Where does time spent on the Internet come from? Tracing the influence of information and communications technology use on daily activities

We explore from a time-use perspective how private use of computers and the Internet [information and communications technologies (ICTs)] is transforming everyday life. Data from the Swedish 2010–2011 Time-Use Survey reflect a situation in which Internet use has spread widely and become routine for many. Using covariate analysis, we analyse differences in general time use between four groups of ICT users ranging from non-users to heavy users. The theoretical departure point is a nuanced discussion of the time-displacement concept. Results indicate that private time spent using ICTs is associated primarily with individuals’ available free time, that is, elastic relative to time for paid work (i.e. contracted time). Heavy ICT users spend more time on activities carried out alone, are more home centred, and less mobile. Heavy use is associated with somewhat less committed time spent, for example, on maintenance work or taking care of children. Regarding personal time, time for meals is negatively related to heavy use, while night-time sleep is unaffected. Concerning free time, heavy use takes time from sports and outdoor recreation, but has no effect on offline media use, entertainment and cultural activities, or reading. Heavy use does not affect time spent on social activities, for example, for social interaction with family and friends or time spent on voluntary associations. Observed differences become significant at certain thresholds of ICT-related time use, involving heavy users who spend one hour or more on computers and the Internet every day.     

Displaced and segregated: The socio-economic status of the second generation of internally displaced Palestinians in Israel

This study investigates the effects of displacement on the socio-economic status of second-generation Palestinian internally displaced persons (IDPs) in Israel. The results show that members of this group do not differ from non-displaced Palestinians in their educational or occupational attainment, but that displaced households experience higher rates of poverty and poorer housing conditions than non-displaced households. I find that the relationship between displacement and the prime indicators of social mobility—education and jobs—was weakened by three factors: extreme spatial segregation between Palestinians and Jews, the concentration of disadvantage among Palestinian IDPs within the host communities, which were Palestinian spaces, and a high level of dependence on resources concentrated in Jewish spaces among all Palestinians, not just IDPs. These three conditions, however, do not eliminate gaps in assets and land ownership between IDPs and non-displaced Palestinians, which, I argue, contribute to higher poverty rates among displaced households.

Responding to economic change in remote, rural regions: federal installations in Idaho and Washington

The federal government's massive spending on nuclear weapons materials and research generated tens of thousands of jobs and pumped billions of dollars into a small number of regions during the 1940s and 1950s. This concentration of financial and physical resources caused the almost overnight formation of small urban centers in what formerly had been remote, rural areas, and made the economies of the regions that surround the two physically largest sites at Hanford and INEEL heavily dependent on nuclear-related government funding. With the end of the Cold War and global agreement to reduce nuclear arsenals, most of these facilities have been made obsolete. More than 10,000 jobs have been recently eliminated and thousands more were lost at private companies providing support services to these facilities and the displaced workers and their families. Further reductions will likely occur within the next 7–10 years. Our research looked at how local leaders in the still largely rural regions surrounding these two Department of Energy (DOE) sites responded to these economic changes, how have the communities reacted to the likelihood that these facilities would never again be a significant economic engine for the region, and what actions are being taken to reduce the impact of significant DOE cutbacks expected in the future? The results raise critical questions regarding the long-term economic future of the two regions and whether a more aggressive multi-faceted effort is required to stave off a long-term decline.
