[Objective] To analyze the key factor in agricultural technology diffusion- technology support, and to explore the method to quicken the diffusion of agricultural technology. [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. [Conclusion] Using social networks for the technol- ogy support will be a powerful supplement to the system of agricultural technology diffusion. 展开更多

Ultrasonic backscatter technique has shown promise as a noninvasive cancellous bone assessment tool. A novel ultrasonic backscatter bone diagnostic (UBBD) instrument and an in vivo application for neonatal bone evaluation are introduced in this study. The UBBD provides several advantages, including noninvasiveness, non- ionizing radiation, portability, and simplicity. In this study, the backscatter signal could be measured within 5 s using the UBBD. Ultrasonic backscatter measurements were performed on 467 neonates (268 males and 199 females) at the left calcaneus. The backscatter signal was measured at a central frequency of 3.5 MHz. The delay (-/-1) and duration (7-2) of the backscatter signal of interest (SOl) were varied, and the apparent integrated backscatter (AIB), frequency slope of apparent backscatter (FSAB), zero frequency intercept of apparent backscatter (FIAB), and spectral centroid shift (SCS) were calculated. The results showed that the SOl selection had a direct influence on cancellous bone evaluation. The AIB and FIAB were positively correlated with the gestational age (|R| up to 0.45, P 〈 0.001) when -/-1 was short (〈 8 μS), while negative correlations (|R| up to 0.56, P 〈 0.001) were commonly observed for T1 〉 10 IJS. Moderate positive correlations (IRI up to 0.45, P 〈 0.001) were observed for FSAB and SCS with gestational age when 71 was long (〉 10 μs). The 7-2 mainly introduced fluctuations in the observed correlation coefficients. The moderate correlations observed with UBBD demonstrate the feasibility of using the backscatter signal to evaluate neonatal bone status. This study also proposes an explicit standard for in vivo SOl selection and neonatal cancellous bone assessment. 展开更多

With the development of Web 2.0 and the gradual maturity of online social media, social network has become an indispensable platform for people' s social interaction, information sharing and news transmission.The study of social networks has become the consensus and urgent need of the academic and industrial circles. 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

This paper takes a cursory look at the conceptual framework of what cultural imperialism entails with particular study of its socio-political consequences in contemporary Nigerian society, and a closer look at the transportation and importation of western cultural values and the implantation of same in Nigeria thereby almost completely eclipsing the hitherto African cultural conservatism of the Nigerian state. 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

The imperial examination system not only has profound influence on prose development in Tang and Song Dynasty, but also has an important influence on the whole Tang and Song Dynasty and even the later literature and cultural development. In the feudal autocratic rule, any system implemented by the state will have an important influence on all aspects of the whole society~ especially it is related with the imperial examination system of education and talents. Once it becomes a "basic national policy" , the role in social development is incalculable. This paper takes the relationship between imperial examination system and Tang and Song prose development as the breakthrough point, analyzing the influence of thesis writing of imperial examination on the prose in Tang and Song Dynasty and "Eight great men in Tang and Song Dynasty" . 展开更多

There are documented differences between the success and failure factors in the developed and developing countries with regard to the adoption and embracement of Openness in e-Government practice models. 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

Sini Power(SP) is a famed traditional Chinese formula that has long been used to treat depression. Here, we investigated the effects and possible mechanisms of SP extract on an established model of depression: chronic stressed tree shrew, which mimics the human condition of social stress. The animals were divided into 4 groups. Except for the na?ve group, the other animals were subjected to daily social defeat stress for 5 weeks, and during the last 4 weeks treated with SP extract(3.6 g/kg/d), fluoxetine(15 mg/kg/d), and vehicle, respectively. The results showed that SP extract could reverse body weight loss to a certain extent and reduce the levels of urine/serum cortisol that were initially increased by chronic social defeat. In addition, SP extract increased hippocampus norepinephrine concentrations. Our data suggested that SP extract had positive effects on the main depression symptoms in the chronic stressed tree shrew model and that it may be used to help control hypothalamic-pituitary-adrenal axis hyperactivity. 展开更多

Universal access to China's social welfare system involves a process of diffusion from localities to the whole country on the basis of social policy innovations in which intergovernmental relations play a key role as a facilitator. 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

This paper focuses on the dynamics of binary opinions {+1,-1} on online social networks consisting of heterogeneous actors. In our model, actors update their opinions under the interplay of social influence and self- affirmation, which leads to rich dynamical behaviors on online social networks. We find that the opinion leading to the consensus features an advantage of the initially weighted fraction based on actors' strength over the other, instead of the population. For the role of specific actors, the consensus converges towards the opinion that a small fraction of high-strength actors hold, and individual diversity of self-amrmation slows down the ordering process of consensus. These indicate that high-strength actors play an essential role in opinion formation with strong social influence as well as high persistence. Further investigations show that the initial fraction of high-strength actors to dominate the evolution depends on the heterogeneity of the strength distribution, and less high-strength actors are needed in the case of a smaller exponent of power-law distribution of actors' strength. Our study provides deep insights into the role of social influence and self-affirmation on opinion formation on online social networks. 展开更多

Natal dispersal, the movement of an organism from its birthplace to the site of first reproduction, is fundamental to many ecological and evolutionary processes. 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

Individual behavioral variation is ubiquitous across taxa and important to understand if we wish to fully use beha- vioral data to understand the ecology and evolution of organisms. Only recently have studies of individual variation in dispersal behavior become a focus of research. A better understanding of individual variation in dispersal behavior is likely to improve our understanding of population dynamics. In particular, the dynamics of critically small populations (endangered species) and large populations (pest species) may be driven by unique dispersal variants. Here we documented individual variation in the ballooning dispersal behavior of Western black widow spiderlings Latrodectus hesperus, an urban pest species found in superabundant in- festations throughout cities of the desert Southwest USA. We found a great deal of family-level variation in ballooning dispersal, and this variation was highly consistent (repeatable) across time. Maternal egg investment was a poor predictor of this ballooning dispersal. Instead, we show that spiderlings reared in isolation are significantly slower to disperse than spiderlings raised in a more natural setting surrounded by full siblings. Thus, our study examines a widespread but poorly understood dispersal behavior (ballooning), and suggests urban pest population dynamics are likely driven by the interaction of variation in individuals, families and social environments 展开更多
