Industry 4.0 stands for 'fourth industrial revolution' and is a term referring to rapid transformations in the design, production, implementation, operation, and service of manufacturing systems, products, and components. To get the most out of Industry 4.0 technologies, organizations will have to heavily invest in building capabilities in the following dimensions: data and connectivity, analytics and intelligence, conversion to the physical world, and human-machine interaction. In this study, the human dimension of industry 4.0 has priority, by analyzing behavioral leadership theories that focus on the study of the specific behaviors of a leader (the leader behavior is the predictor of his leadership influences and is the best determinant of his leadership success). A two dimensional 4.0 leadership style matrix was developed (x-axis: innovation/technology concern; y-axis: people concern). The results of this study revealed that the developed industry 4.0 leadership style might have the dimensions of first-year students, social, technological or digital, where the 4.0 digital leader forms the highest reachable level in the 4.0 leadership matrix.

The effect of the Volkswagen emission crisis in 2015, the biggest greenwashing event in recent years, on the online consumer engagement of Facebook brand pages was investigated in France, Germany, Turkey, and the United Kingdom. These countries have been selected for the reason that Volkswagen sales and diesel-engine cars and the use of social media are quite common. For 6 years in these four countries, the likes, comments, and shares made by consumers on the Facebook brand page of Volkswagen have been examined. The monthly dataset covers January 2012 to December 2017. The obtained data were analyzed with autoregressive-moving average models. Despite a globally positive approach to green products, countries' attitudes toward greenwashing have been significantly different. The findings showed that online consumer engagement was negative in the United Kingdom and Turkey and in a positive direction in Germany, whereas there was no change in France in the fourth quarter of 2015.
