Additional Sources of Interest

• While academic journals that focus on digital advancements (ex. technology or Big Data) focus more on the implications of such advancements, rather than the "human" side of its management, there are other journals that might prove of interest. Under Scimago's listing, there is a category called "Management of Technology and Innovation". While some journals have already been mentioned above, a journal based in the Netherlands called "Journal of Business Venturing" might be useful. Technovation, out of the UK, studies all aspects of technological innovation including the "technological innovator as an entrepreneur, team-member, manager or employee".
• Rigorous studies are not only conducted under the auspices of academic journals; several business-focused magazines and publishers conduct credible studies of their own.

Academic Work

• According to a study conducted by Dr. Christina Boedker in Australia for the Society for Knowledge Economics showed that when a leader could be empathetic and compassionate, then the organization was most profitable and productive. She based this on studying 5600 people across 77 organizations. She then defined compassionate leadership as "to understand people's motivators, hopes and difficulties and to create the right support mechanism to allow people to be as good as they can be". This is similar to what Google espouses in its leaders.
• An article in the Journal of Management Studies (UK-based although articles from all over the world are accepted), a study that focused on leaderships in nascent teams (as with a startup) showed that an individual's tendency to suppress emotions was negatively correlated to their emergence as leaders, while their ability to reappraise emotions correlated positively to their leadership. The article contains numerous links and citations to articles on similar topics.
