This paper describes the design, execution, and results of a participatory design workshop with emergency public information officers (PIOs). During the workshop, PIOs and researchers explored ideas and designs for supporting the social media needs of PIO work. Results indicate that PIO perceptions of social media have changed as they have learned to incorporate activities of the public into th...

Two programs, containing fictitious subject matter, were employed in a study designed to compare the teaching effectiveness (as measured by posttest) of textual material presented (1) as contingencies for responses in a program, or (2) as material upon which responses were not contingent. The content of the programs was identical, and they differed only in that material whose reading was necess...

Although greeting parents by name facilitates subsequent parent-teacher communication, baseline measures revealed that 4 preschool teachers never or rarely greeted parents by name during morning check-in. To promote frequent and accurate use of parents' names by teachers, the effects of a fully automated computerized assessment and programmed instruction (CAPI) intervention were evaluated in a ...

In one simulation, an artificial neural network was trained to rate the distances between pairs of cities on the map of Alberta, given only place names as input. Distance ratings ranged from 0 (when the network rated the distance between a city and itself) to 10. The question of interest was the nature of the representations developed by the network’s six hidden units after it successfully lear...

objective: breast cancer is the second leading cause of cancer death in women. cisplatin is a traditional cancer drug commonly used in chemotherapy for killing cancer cells. modulation at the mrna levels of apoptotic related genes often correlate with the sensitivity of various types of cancer cells to chemotherapeutic agents. nanoparticulate drug delivery systems are being developed to effecti...

For generations programmed mammal aging was widely thought to be theoretically impossible. However, new evolutionary mechanics concepts have led to renewed interest in programmed aging resulting in a schism between programmed and non-programmed proponents. This article argues that this lack of consensus is damaging medical research and therefore steps should be taken to pro-actively resolve the...
