The Qing Dynasty had many challenges when ruling a majority Chinese based population. Although, initially the Manchus had control of the army and they also followed along with the Chinese's bureaucracy whereas their Mongol counterparts earlier did not. The Manchu's decision to continue the Chinese' bureaucracy was an important one as it allowed for them to be much more accepted by the Chinese population. The opium trade had severe effects in allowing the Manchu military to deal with the rebellions. However, in the 19th century, the ability not to meet modernization standards comparable to the foreign powers saw much weakness in the Manchu's military. As well, as the failure of the scholar-officials reporting much of the rebellions success due

I have found these concepts very interesting and practical. Within the last twelve months we have five new project managers join our team. All have a few years of experience under their belt, but have never held a formal leadership position.

Many times I have seen peers get jealous of someone that seems to be a natural born leader, but in this case Joe has moved into an informal leadership position with his peers. He also has been assigned to different teams and quickly become the informal leader or co-leader of each team. I believe it would be helpful to take a closer look at Joe’s cognitive skills, personality traits, and his motivation to lead. If we can determine that Joe does possess many of the skills and traits recognized in emerging leaders I am confident this knowledge will help the leadership team quickly recognize other emerging leaders that we would want to recruit into our organization.
