This research—a pilot study on the cognitive mediation model (CMM) in Singapore—seeks to revisit and test the applicability of an extended CMM in the context of nanotechnology by examining perceived familiarity as a separate outcome variable in addition to factual knowledge. A cross-sectional survey was administered to a nationally representative sample of 719 adult Singaporeans. Results demonstrated partial support for the hypothesized CMM. First, elaboration was positively associated with both factual knowledge and perceived familiarity, whereas interpersonal discussions about science was associated only with familiarity. Results also showed differential relationships between attention to media platforms (traditional vs. new media) and reflective integration (composed of elaborative processing and interpersonal discussion); whereas attention to science reporting in newspapers and science television programs were associated with elaboration, media attention across all platforms were associated with interpersonal discussions. Theoretical and practical implications are discussed. 相似文献

INTRODUCTION Wireless mesh networks (WMNs) are ad-hoc networks with full or partial mesh topologies, where nodes can automatically establish and maintain mesh connectivity among themselves. Such a mesh topol- ogy provides each node multiple communication paths to reach its peers. In the presence of link failures caused by, for example, node failures or interference, information can be rerouted through alternative paths to the destination. WMNs have no fixed infrastructure and are easily… 相似文献

A potential undesirable effect of multistage testing is differential speededness, which happens if some of the test takers run out of time because they receive subtests with items that are more time intensive than others. This article shows how a probabilistic response-time model can be used for estimating differences in time intensities and speed between subtests and test takers and detecting differential speededness. An empirical data set for a multistage test in the computerized CPA Exam was used to demonstrate the procedures. Although the more difficult subtests appeared to have items that were more time intensive than the easier subtests, an analysis of the residual response times did not reveal any significant differential speededness because the time limit appeared to be appropriate. In a separate analysis, within each of the subtests, we found minor but consistent patterns of residual times that are believed to be due to a warm-up effect, that is, use of more time on the initial items than they actually need. 相似文献

The living cells are arranged in a complex natural environment wherein they interact with extracellular matrix and other neighboring cells. Cell-cell interactions, especially those between distinct phenotypes, have attracted particular interest due to the significant physiological relevance they can reveal for both fundamental and applied biomedical research. To study cell-cell interactions, it is necessary to develop co-culture systems, where different cell types can be cultured within the same confined space. Although the current advancement in lab-on-a-chip technology has allowed the creation of in vitro models to mimic the complexity of in vivo environment, it is still rather challenging to create such co-culture systems for easy control of different colonies of cells. In this paper, we have demonstrated a straightforward method for the development of an on-chip co-culture system. It involves a series of steps to selectively change the surface property for discriminative cell seeding and to induce cellular interaction in a co-culture region. Bone marrow stromal cells (HS5) and a liver tumor cell line (HuH7) have been used to demonstrate this co-culture model. The cell migration and cellular interaction have been analyzed using microscopy and biochemical assays. This co-culture system could be used as a disease model to obtain biological insight of pathological progression, as well as a tool to evaluate the efficacy of different drugs for pharmaceutical studies. 相似文献
