[Method] The technology acquisition advantage of social network was il- lustrated by summarizing the status and characteristics of agricultural technology and technology supporting types in the process of agriculture technology diffusion. [Result] The multi-layer, complex, persistence, systematization features of agricultural technol- ogy require support and help of technology from surrounding social network to ulti- mately internalize the technology.

The prediction of information communication is the core function of social network, and it is also the core content.To be specific, this paper briefly introduces the concept of social network, then summarizes the diffusion prediction models and methods from five aspects, namely, user attributes-based, information characteristics-based,user groups-based, statistic and inference-based and network topology -based models. Finally, the directions for the future research are discussed.展开更多

Clear examples of this cultural transplant are given in this work, including but not limited to the use of English language in place of the indigenous languages for communication even when there are no foreigners, smoking of cigarettes, ladies putting on trousers, abortions as a means of birth control, free premarital and extramarital sexual relationships, and homosexuality and gay practices. These which were viewed as an anathema to Nigeria＇s cultural values have supplanted the traditional conservatism of the Nigerian people. This work particularly looks at Chimamanda Adichie＇s Purple Hibiscus and distills classical cases of cultural imperialism. Adichie through the character Eugene, captures cultural imperialism as seen in the life of this vastly brainwashed ＂been-to＂ who is clearly portrayed as an imperial lackey, capitalist, and apologist. Also, the character of Rev. Father Benedict, a Briton, who often found any indigenous songs in St. Agnes Parish was quite offensive. The work also captures cultural imperialism in the ironical contempt with which the catholic devotee, Eugene, treats his own father, Papa Nnukwu, steeped in the traditional African cultural values, and Eugene viewes him as Godlessness. The essay concludes by identifying the cultural crises that cultural imperialism creates in the Nigerian state, and recommends ways of diluting and diffusing the present cultural imperialism as a solution to the myriad of socio-political crises currently experienced by the Nigerian society.展开更多

This paper posits that e-Government constitutes a critical context for social and economic development in both developed and developing countries. The paper also suggests that e-Government encompasses more than just technology, that is, attempts to highlight the social and economic implications of changes that have occurred in recent years as a result of the transparency and accountability of government and how software usage can influence digital inclusion, trust and privacy and possible strategies to eliminate the digital divide by encouraging greater public and commercial use and re-use of government information through putting govermnent data on the Web. In addition to leveraging economic development, e-Government also helps to stream line govemment services to more social based values of inclusion and citizens＇ participation, accessibility and power relationship ratios. Although e-Government is not a new phenomenon in most developed countries such as the US, UK, Japan, most of the European countries and some developing countries in Asia and Africa which have already announced their Open Government Initiatives and data portals it also leads to greater information asymmetry among citizens and government and also, institutionalization and diffusion asymmetry of the practice of the current Openness in e-Government models within developed and developing countries. Drawing on organizational decision-making research and following the explorative and grounded based research approach the findings of this research are that the information asymmetry between citizens and government and asymmetry in institutionalization and diffusion within developed and developing countries are widely attributed to socio-economic and political variations in developed and developing countries. Unless these differences are skill fully identified and accommodated as such into the development and use models, Openness in e-Government efforts would not help achieve the social and economic development goals by both developed and developing countries.展开更多

Mechanistically, individual dispersal decisions can depend on both individual phe- notype and environmental cues. In particular, many established evolutionary theories of dispersal highlight the importance of the social environment. More recent research in behavioral ecology has focused on the importance of individual behavioral pheno- types. We reviewed the literature on individual behavioral phenotypes and dispersal and suggest that how individual behavioral phenotypes interact with the immediate social environment experienced by individuals in influencing dispersal is still poorly un- derstood, despite growing interest. We found that very few studies had examined the interaction of individual behavioral pheno- types and social factors, and behavioral phenotypes related to social tendencies were less commonly measured than were beha- vioral phenotypes related to exploration or response to risk. Further, and unsurprisingly, studies on social behavioral phenotypes and dispersal behaviors during the transience stage of dispersal were underrepresented compared to the departure or settlement stages. Future studies in this area should aim to＂ a） make explicit links between behavioral traits and their proposed effects on dispersal decisions throughout multiple stages of dispersal, b） integrate more continuous dispersal variables, and c） consider the effects of the spatial distribution and phenotypes of conspecifics （i.e., the social landscape） encountered by individual dispersers展开更多

The rapid establishment of the urban subsistence allowance system in more than 200 cities throughout the country in seven years （1993-1999） serves as a case for our empirical analysis of the diffusion mechanism of social policy innovations at different levels of government. Our findings show, firstly, that in adopting a new social policy, city governments have to respond to the social desire of local citizens while keeping fiscal constraints in mind; at the same time, they are affected by administrative orders from higher-level governments and the vertical fiscal relations between governments at different levels, and are also subject to competitive pressures from other cities at the same level. Secondly, city governments＇ policy innovations offer an opportunity for higher levels of government to learn from their experience. Thirdly, central government orders exert both a direct and indirect influence upon city governments, with provincial orders acting as intermediaries. And lastly, there is a clear difference in the time lag effect of orders from the central government and those at provincial level upon city governments＇ policy adoption.展开更多
