    N° 4. — Oxydation du zinc aux hautes températures. Cinétique de l’oxydation du zinc dans une atmosphère d’oxygène et de bioxyde de carbone

    Les auteurs présentent quelques résultats au sujet de l’oxydation du zinc soumis à des températures de 370-400 °C, dans une atmosphère d’oxygène et de bioxyde de carbone à la pression normale afin de vérifier l’influence de la pression partielle de l’oxygène sur la valeur de la constante de la vitesse de réaction.Les résultats des essais effectués mènent à la conclusion qu’aux températures de 370-400 °C (pourvu que l’épaisseur du film dépasse 100 Å) et dans le domaine où la loi parabolique d’oxydation est applicable, la pression partielle de l’oxygène influe sur la vitesse d’oxydation du zinc, ce qui signifie que le modèle dû à Wagner, pour la formation des oxydes de type n, dans le processus d’oxydation de certains métaux, a besoin d’être revisé

    The rise of digital intelligence: challenges for public relations education and practices

    Purpose This research paper explores the development of four categories of skills (operational, informational, strategic and digital fluency) as dimensions of the digital intelligence. The purpose of the pilot study is to determine the consequences of these gaps on PR practices and the directions for educational adaptation.Design/methodology/approach A questionnaire was applied on a convenience sample of 98 PR students from Romania, in March 2014. The majority of students (n = 88) were of 20 to 25 years of age.Findings The results of the survey showed an approximately equal level of development for each of the four skills in the sample of PR students (with a lower degree for the information skills). The general level of development is rather good and shows that the digital literacy acquirement is a need for the specialists from older generations to communicate with younger publics.Research limitations/implications The third category of skills (strategic skills) has been coded as a set of actions - instead of being coded as a set of self-assessed abilities - which created differences in measuring.Originality/value The results showed the level of public relations students related to the development of new skills in the digital environment

    Understanding health behavior: An integrated model for social marketers

    No full text
    Many effective social marketing campaigns seek to change health-related beha-vior by utilizing various health-protective behavioral theories. In this article, we review and integrate three such theories: protection motivation theory (PMT), the extended parallel process model (EPPM), and the transtheoretical model (TTM). We highlight how EPPM and TTM can be used to refine PMT by add-ing insight into the decision-making process involved when consumers consider whether or not to follow a particular recommended health behavior. Specifically, the development of an integrated PMT model can provide insight into the char-acteristics of people more or less likely to change, what happens when persuasion fails, and what can be done to increase persuasion. Developing an integrated PMT model opens new avenues of research that have the potential to increase our understanding of behavior and assist in creating more persuasive social marketing campaigns
