How Graphic Visual Health Warnings Affect Young Smokers\u27 Thoughts of Quitting

Two-thirds of adolescent and young adult smokers become lifetime smokers, and one-half of those lifetime smokers will die from this habit. The authors examine alternative persuasive pathways to thoughts of quitting taken by adolescent and young adult smokers when exposed to graphic visual health warnings on cigarette packages. For adolescent smokers, the authors find that graphic warnings and smoking frequency affect fear, and fear influences negative health beliefs about smoking, ultimately increasing thoughts of quitting. They also find that the graphic warning and a graphic warning × smoking frequency interaction have incremental effects on quit thoughts beyond the effects of fear and negative health beliefs. Using a longitudinal design with a sample of young adult smokers, the authors find support for many of the adolescent smoker findings, particularly the incremental effects of graphicness and its interaction with smoking frequency. These similar results from diverse samples support the use of graphic visual warnings but suggest that effects are attenuated for those who smoke the most. The authors offer implications for countermarketing programs and public health policy

Investigating the socio-constructivist dimension of online interactions: the case of synchronous audio-graphic conferencing systems

This study explores the quality of interactive patterns in audio-graphic conferencing environments and learners' involvement in interaction. Supporters of this technology claim that online interactions support socio-constructivist language learning. However, the existing literature does not indicate whether the quality of interaction required for realising constructivist principles of learning can affectively be ensured in such environments. The study is based on the Open University's online audio-graphic tuition environment, Lyceum. It investigates the verbal and written interactions of adult Open University students learning French. The data is analysed by different models of analysis pertaining to different socio-constructivist and cognitive models of analysis. The results show that students use high forms of thinking to engage in a cyclical rather than a linear process of knowledge construction. However, there is no evidence that this process is supported by the audio-graphic system itself. The tutor's style and task design play a more important role in supporting the learning process

Creating visual aids with graphic organisers on an infinite canvas : the impact on the presenter

Instead of the traditional set of slides, the visual aids of a presentation can now be graphic organisers (concept maps, knowledge maps, mind maps) on an infinite canvas. Constructing graphic organisers has a beneficial impact on learning, but this topic has not been studied in the context of giving a presentation. The present study examined this issue by having 199 students prepare a presentation. The control sample created visual aids that are similar to a deck of slides with text and pictures. In the first experimental condition, graphic organisers were inserted in this deck of slides, and in the second experimental condition, visuals aids with interconnected graphic organisers were produced. There were no significant differences in self-reported self-efficacy related to giving a presentation and in motivational variables. To detect if the presentations met the principles set by the conditions, the participants’ products were coded qualitatively, but this analysis also yielded no differences in variables. Further research should therefore explore the interaction between software and presenter

Display system for imaging scientific telemetric information

A system for imaging scientific telemetric information, based on the M-6000 minicomputer and the SIGD graphic display, is described. Two dimensional graphic display of telemetric information and interaction with the computer, in analysis and processing of telemetric parameters displayed on the screen is provided. The running parameter information output method is presented. User capabilities in the analysis and processing of telemetric information imaged on the display screen and the user language are discussed and illustrated

Electron interaction in matter

Data on the scattering of 1-MeV electrons in aluminum for the case of non-normal incidence, electron-bremsstrahlung cross-sections in thin targets, and the production of bremstrahlung by electron interaction in thick targets, are presented both in tabular and graphic form. These results may interest physicists and radiologists

Distance and virtual distance: Preliminary results of a study of interaction patterns in synchronous audio graphic CMC and face-to-face tutorials in beginners’ language tutorials

This paper presents preliminary results of a larger study of interaction patterns in beginners’ language tutorials held at the Open University. The tutorials are voluntary, supplementing a distance learning course in German as a Foreign Language. Tutorials are offered in two versions: traditional face-to-face tutorials in a classroom or online tutorials held through an internet based audio-graphic conferencing system. Interaction patterns are compared between the two modes of presentation, between different tasks performed by students and between different tutors initiating the same task. Results of the completed study will be published in 2005 / 06

Bulk properties of light deformed nuclei derived from a medium-modified meson-exchange interaction

Deformed Hartree-Fock-Bogoliubov calculations for finite nuclei are carried out. As residual interaction, a Brueckner G-matrix derived from a meson-exchange potential is taken. Phenomenological medium modifications of the meson masses are introduced. The binding energies, radii, and deformation parameters of the Carbon, Oxygen, Neon, and Magnesium isotope chains are found to be in good agreement with the experimental data.Comment: 10 pages, LaTeX2e, elsart, 4 eps-figures includes with graphic
