The concept of safety culture is characterised by complexity. On the one hand, the concept is challenging content-wise, and on the other hand, is it a multi-dimensional and cross-disciplinary research domain. In this paper, bibliometric analysis has been applied to the field of safety culture to identify fundamental influences and to obtain a structured overview of the characteristics and the developments in this research domain. In total, 1789 publications published between 1900 and 2015 related to safety culture were identified in Web of Science. The 1789 publications cover 4591 authors, 775 journals, 76 countries or territories, and 1866 institutions. Two main research areas can be distinguished in the domain of safety culture: (1) organisational safety culture and (2) health-care and patient safety culture. The latter research area stands in a dominant position in safety culture research nowadays. Key publications are from Guldenmund (2000) and Sexton et al. (2006). Furthermore, 'Safety Science' is the key journal publishing on safety culture research, and the USA, England and China are the countries that dominate the publication production. It can be concluded that there is much collaborative research in the safety culture domain as multi-authored publications make up about three quarters of all publications. Also, safety culture research is characterised by a wide variety of research themes and multidisciplinarity. Geographical inequality in the publication output is identified as. a point of concern. A movement away from technical aspects towards more human aspects could be detected as a noteworthy change in research focus.

A Li₄WO₅ ceramic with rock salt structure was prepared by the solid-state reaction method and its microwave dielectric properties was demonstrated for the first time. It could be well densified at relatively low sintering temperature (~890°C). XRD and DTA analysis revealed a phase transformation from cubic to orthorhombic occured at 700°C. Excellent microwave dielectric properties with a near-zero temperature coefficient of resonant frequency ~-2.6ppm/°C, a relative permittivity ~8.6 and a quality factor ~23,100GHz (at 11.0GHz) was obtained. Li₄WO₅ was found to be chemically compatible with silver powders when sintered at 890°C. All the results indicate that the Li₄WO₅ ceramic is a promising candidate as a base material in low temperature cofired ceramic technology.

The topic of domino effects in the process industry started to receive attention in risk analysis and safety assessment studies over the last two decades. The popularity of the topic is partly due to the occurrence of catastrophic industrial accidents involving domino effects, e.g., the LPG-induced domino effects in Mexico City in 1984, and partly due to legislation (e.g. the so-called “Seveso Directives”), mandating the owners and managers of chemical plants to take the likelihood of domino effects into account when contemplating the prevention/mitigation of major accidents. The present study aims to take advantage of state-of-the-art bibliometric analysis tools to investigate the trend, the geographical and the authorial distributions of scientific papers on domino effects published in peer-reviewed journals around the globe. The result of this study can be used to identify the most influential research institutes and authors contributing to the domain of domino effects in the chemical industry.@en
