Motivation and Knowledge Sharing through Social Media within Danish Organizations
Part 3: Creating Value through ApplicationsInternational audienceBased on an empirical quantitative study, this article investigates employee motivation in Danish companies and aims at determining which factors affect employeesâ knowledge sharing through social media in a working environment. Our findings pinpoint towards the potential social media have for enhancing internal communication, knowledge sharing and collaboration in organizations, but the adoption is low, at this point, due to mainly organizational and individual factors. Technological factors do not seem to affect employeesâ motivation for knowledge sharing as much as previous research has found, but it is the influence from the combination of individual and organizational factors, which affect the adoption of the platforms. A key finding in the study is that knowledge sharing is not a âsocial dilemmaâ as previous studies have found. The study shows a positive development in employeesâ willingness to share knowledge, because knowledge sharing is considered more beneficial than to hoard it
Antimicrobial efficacy of mixtures of silver nanoparticles and polyhydric alcohols against health-promoting bacteria
In the present study, the effectiveness of a mixture
of silver nanoparticles with polyhydric alcohols (glycerol,
erythritol, mannitol and xylitol) against six species of healthpromoting
bacteria have been examined. Synthesis of silver
nanoparticles was carried out using trisodium citrate as the reducing
and stabilizing agent. The nanoparticles were characterized by
electronic absorption, scanning electron microscopy and powder
X-ray diffraction measurements. Electronic absorption spectrum
revealed high uniform of synthesized nanoparticles. Practically no
aggregation was observed when nanoparticles were mixed with
polyhydric alcohols, suggesting weak interaction between ingredients
of the mixture. Spherical silver nanoparticles, as depicted
by scanning electron microscopy, were found to have diameters
in the range of 10 to 30 nm; mean diameter was 18 ± 4 nm. The
X-ray diffraction pattern of the prepared samples indicated the
face-centred cubic crystalline structure of the metallic silver nanoparticles.
In biological study, quite interesting protective effect of
polyalcohols on the growth inhibition of health-promoting bacteria
by silver nanoparticles was observed. The most substantial
protective effect of the tested silver nanoparticles-polyalcohol
mixtures was estimated for B. bifidum, L. paraplantarum, and L.
phamnosus species
