Analyzing Effective Leaders: Why Extraverts Are Not Always the Most Successful Bosses - Knowledge@Wharton
Conventional wisdom tells us that leaders are the men and women who stand up, speak out, give orders, make plans and are generally the most dominant, outgoing people in a group. But that is not always the case, according to new research on leadership and group dynamics from Wharton management professor Adam Grant and two colleagues, who challenge the assumption that the most effective leaders are extraverts.
In fact, introverted leaders can be more effective than extraverts in certain circumstances. The determining factor is who leaders are managing, according to Grant and co-authors Francesca Gino of Harvard Business School and David Hofmann of the University of North Carolina's Kenan-Flagler Business School. Their paper, forthcoming in the Academy of Management Journal, is titled "Reversing the Extraverted Leadership Advantage: The Role of Employee Proactivity."
Better, Faster, Customizable: Who Will Win the Browser Battle? - Knowledge@Wharton
In the world of web browsers, it's beginning to look a lot like the 1990s. Back then, the Internet was just starting to become an integral part of daily life and Netscape's Navigator and Microsoft's Internet Explorer vied for dominance in helping users surf the web. By the end of the decade, Microsoft emerged the winner and Netscape faded into dotcom history.
This time around, the browser battle includes an increasing number of competitors, most notably Internet Explorer, Mozilla's Firefox and Google's Chrome. But players such as Apple's Safari and newcomers like RockMelt, a start-up that promises to integrate web browsing with social networking, are banking on innovative features to stand out in a sector where users are reluctant to change -- or are unaware of myriad options beyond their browser of choice.
