The most influential data scientists on Twitter Twitter is emerging as an important medium for determining influence in many fields. Social ranking sites like Klout and Traackr include Twitter as a heavily-weighted component of their ranking algorithms, for example. Twitter isn't representative of the members of any field, but in areas where the members primarily engage online, it can be a useful proxy. SocialFlow's Gilad Lotan has used an analysis of social networks on Twitter to rank influences in such fields, including the communities of python users and data scientists. Each circle represents a data scientists on Twitter (anyone with Data Science, Data Scientist, Machine Learning, Data Strategy or the like in their bio). The colors represent connected clusters within the social graph, detected autonomously. Purple seems to be a mix of east coast and academics, while the dark blue is the west coast data drinking crew. The analysis of the social network code was performed with Python, and the visualization was created with Gephi.

Complainers in the Office: 3 Ways to Deal With Them Do you hate it when people complain? It turns out there's a good reason: Listening to too much complaining is bad for your brain in multiple ways, according to Trevor Blake, a serial entrepreneur and author of Three Simple Steps: A Map to Success in Business and Life. In the book, he describes how neuroscientists have learned to measure brain activity when faced with various stimuli, including a long gripe session. "The brain works more like a muscle than we thought," Blake says. Even worse, being exposed to too much complaining can actually make you dumb. But if you're running a company, don't you need to hear about anything that may have gone wrong? So, how do you defend yourself and your brain from all the negativity? 1. "My father was a chain smoker," Blake confides. You should look at complaining the same way, he says. 2. Sometimes getting distance isn't an option. "Try to get the person who's complaining to take responsibility for a solution," Blake says. 3.

3 Ways To Make Everyone Around You Smarter Leaders accept and act on the paradox of power: you become more powerful when you give your own power away. Long before empowerment was written into the popular vocabulary, exemplary leaders understood how important it was for their constituents to feel strong, capable, and efficacious. Constituents who feel weak, incompetent, and insignificant will consistently underperform; they want to flee the organization and are ripe for disenchantment, even revolution. People who are not confident about their power, regardless of their organizational position or place, tend to hoard whatever shreds of influence they have. Powerless managers tend to adopt petty and dictatorial styles. Feeling powerful--feeling "able"--comes from a deep sense of being in control of your own life. Failing to do so creates dependency, and is the way of the Diminishers. Provide Choices You want people to take initiative and be self-directed. Structure Jobs to Offer Latitude Foster Accountability
