Serial killing follows predictable pattern based on brain activity

Via Scoop.itLogicamp

Over a period of 12 years, Andrei Chikatilo murdered at least 53 people before being arrested in Rostov, Russia, in 1990. While Chikatilo’s killings, mainly of women and children, may have been senseless, a new study has found some sense in the distribution of intervals between the murders, which closely follows a power law. The researchers propose that the murder activity can be explained by a model describing neuronal firing in the brain, very similar to the model that describes the distribution of intervals between epileptic seizures.

The role of Twitter in Personal Learning Networks

Via Scoop.itLogicamp

« Abstract   This qualitative phenomenological study involving in-depth interviews with seven educators in K-12 and higher education examines the role that the microblogging service Twitter plays in the formation and development of Personal Learning Networks (PLN) among educators. A double hermeneutic data analysis shows that Twitter plays a role in the formation and development of PLNs by allowing educators to; engage in consistent and sustained dialogue with their PLN, access the collective knowledge of their PLN, amplify and promote more complex thoughts and ideas to a large audience, and expand their PLN using features unique to Twitter. This research also examines the nature of a PLN and shows that participants believe their PLN extends beyond their Twitter network to encompass both face-to-face and other ICT mediated relationships. Secondary research questions examine how Twitter differs from other social networking tools in mediating relationships within a PLN, what motivates an educator to develop a PLN, how trust is established in a PLN, what the expectations of reciprocity are within a PLN, and what is the nature of informal learning within a PLN.   http://dspace.royalroads.ca/docs/handle/10170/451″
