After the 9/11 terrorist attacks, the U.S. government initiated several national security technology adoption programs. The American public, however, has been skeptical about these initiatives and adoption of national security technologies has been mandated, rather than voluntary. We propose and test a voluntary behavioral intention formation model for the adoption of one type of new security technology: portable radiation detectors. Portable radiation detectors are an efficient way of detecting radiological and nuclear threats and could potentially prevent loss of life and damage to individuals’ health. However, their functioning requires that a critical mass of individuals use them on a daily basis. We combine the explanatory advantages of diffusion of innovation with the predictive power of two volitional behavior frameworks: the theory of reasoned action and the health belief model. A large sample survey (N = 1,482) investigated the influence of factors identified in previous diffusion of innovation research on portable radiation detector adoption intention. Results indicated that nonfinancial incentives, as opposed to financial incentives, should be emphasized in persuasive communications aimed at fostering adoption. The research provides a new integration of diffusion of innovation elements with determinants of volitional behavior from persuasion literature, and offers recommendations on effective communication about new security technologies to motivate public adoption and enhance national safety. 相似文献

Estimation for Discretely Observed Small Diffusions Based on Approximate Martingale Estimating Functions 总被引:2,自引:0,他引:2
Masayuki Uchida 《Scandinavian Journal of Statistics》2004,31(4):553-566
Abstract. We consider an asymptotically efficient estimator of the drift parameter for a multi-dimensional diffusion process with small dispersion parameter ɛ . In the situation where the sample path is observed at equidistant times k / n , k = 0, 1, …, n , we study asymptotic properties of an M -estimator derived from an approximate martingale estimating function as ɛ tends to 0 and n tends to ∞ simultaneously. 相似文献

This paper presents an approach to assessing the potential of countries to lead the global adoption of an innovation and to set a global product or process standard. It can be observed that the specific design of an innovation diffuses worldwide after it has been adopted in a single country. We suggest that there are nation-specific characteristics that increase the likelihood that a locally preferred innovation design will become successful in other countries, too. Once users in a market that has lead market characteristics have adopted a specific innovation design, the possibility increases that users in other countries subsequently adopt it as well. We present a lead market concept for the development of global innovation designs. By focusing on the design of the innovation that responds to the preferences within the lead market, a company can leverage the success experienced in the lead market for a global market launch. In order to follow a lead market strategy of new product development, it is necessary to assess the lead market potential of countries before an innovation is developed and tested in the market. We use an indicator-based methodology that approximates the lead market attributes of countries. The assessment methodology is applied to two innovation projects at the truck division of DaimlerChrysler. 相似文献

The relation of the within-season and between-season patterns of shoot growth were compared in a clonal grass with long-lived
shoots,Festuca rubra, in a mown mountain grassland. The growth rate of shoot length from spring to summer in a year was almost constant for each
shoot irrespective of spring shoot length each year. The annual shoot growth rate from spring to spring was negatively correlated
with the shoot length in the first spring. Shoots of different length and age therefore tended to converge over time to a
population of identical shoot size, suggesting an equalizing effect of growth pattern on size structure. Shoot size (shoot
length and number of leaves) influenced the fates of shoots. Larger shoots showed an increased incidence of both flowering
and formation of intravaginal daughter shoots and a decreased incidence of death in the subsequent time period. The fates
of shoots were independent of their age. Although the negatively size-dependent springto-spring annual shoot growth rate acted
to decrease shoot size variation, the remaining variation within the shoot population was still sufficient to generate different
fates of shoots. These fates were not related to the previous life history of individual shoots. There was a significantly
positive effect of the shoot size at initiation on its life expectancy. This was mainly attributable to the positively size-dependent
survival rate of shoots in the early stage (<1 year old) of shoot life history. Later on (> 1 year old), shoot size had little
effect on the survival rate of shoots. Once small young shoots have survived this early stage (< 1 year old) in life history,
they can grow vigorously, little affected by competition regardless of shoot size, and converge to a stable size structure
of shoots of similar size. Only shoot size in the early stage ( < 1 year old) of life history is important for the persistence
of a shoot population. 相似文献

农业技术扩散分析——以杨凌农业示范区为例 总被引:1,自引:0,他引:1
农业技术扩散对解决“三农”问题、城乡二元结构、城乡统筹发展和农业可持续发展起到决定作用。农业技术扩散的理论主要有框架理论、沟通理论、农户行为改变理论和技术创新扩散理论。分析杨凌农业示范区技术扩散的基础上,认为自然条件决定农业技术扩散的内容和方式;历史基础和人文条件决定技术扩散的速度和效果;政治、市场机制对农业技术扩散起到加速或减缓作用;市场化和网络化是农业技术扩散的动力机制。 相似文献
