More and more information system applications have been adopted in China. Telecom operators in China are applying information services and solutions to more and more sectors and areas, of which the rural area is a typical example. Firstly, the paper describes the architecture of the mobile information system which is based on telecommunication terminals and is realized through text messaging, v...

The farming community, in many parts of Australia is widely dispersed and is heavily dependant upon communication both within the community and outside. Following Department of Primary Industry initiatives, at both State and Federal level, to move to provide information to farmers via the Web rather than via a cadre of Extension officers, the expected increased penetration of the rural sector b...

Amenity migration to attractive and accessible non-metropolitan areas changes social and environmental relations with consequences for natural resource management and landscape composition and trajectories. Lifestyler oriented rural landholders are often cast as a problem for land management and extension. Managers and some researchers see them as a cause of landscape and social fragmentation a...

Land in rural China has been under a separate and closed management system for decades even after the urban land reform that started in the late 1980s. The blurred property rights over rural land have been hindering the rural welfare as surplus rural land in sub-urban areas cannot be circulated into more economic use without first being requisitioned by the state. This traditional conversion pr...

The patterns of proteins synthesized in animal and vegetal regions of Xenopus oocytes, eggs and embryos were examined by 2D gel electrophoresis. In oocytes and eggs, the only proteins synthesized asymmetrically along the animal-vegetal axis were a small number of proteins synthesized predominantly in the vegetal hemisphere. At the cleavage stage there were a total of four proteins synthesized u...

In sea urchin embryos, the animal-vegetal axis is specified during oogenesis. After fertilization, this axis is patterned to produce five distinct territories by the 60-cell stage. Territorial specification is thought to occur by a signal transduction cascade that is initiated by the large micromeres located at the vegetal pole. The molecular mechanisms that mediate the specification events alo...

Interstate highways are a permanent and increasingly important feature of America’s rural landscape. Their impact on agriculture and rural living, which is already felt, w ill be greatly intensified in the next few years. Consider some of the overall dimensions of this new highway system. Of the 41,000 miles authorized, more than 35,000 miles are classed as rural. ( 1 ) * One-third of all count...

Agricultural nutrients play a critical role in food production and human nutrition in China. Against this backdrop, agricultural extension services are essential for providing farmers with knowledge and information about nutrient management. By using a propensity score-matching (PSM) approach, this study examines the impact of agricultural extension on farmer nutrient management behavior. Surve...

Does poverty lead to stress? Despite numerous studies showing correlations between socioeconomic status and levels of the stress hormone cortisol, it remains unknown whether this relationship is causal. We used random weather shocks in Kenya to address this question. Our identi cation strategy exploits the fact that rainfall is an important input for farmers, but not for non-farmers such as urb...
